FORWARD In March 2001, the National Institutes of Health issued the following warning: "The number of Web sites offering health-related resources grows every day. Many sites provide valuable information, while others may have information that is unreliable or misleading."1 Furthermore, because of the rapid increase in Internet-based information, many hours can be wasted searching, selecting, and printing. Since only the smallest fraction of information dealing with hepatitis B is indexed in search engines, such as www.google.com or others, a non-systematic approach to Internet research can be not only time consuming, but also incomplete. This book was created for medical professionals, students, and members of the general public who want to know as much as possible about hepatitis B, using the most advanced research tools available and spending the least amount of time doing so. In addition to offering a structured and comprehensive bibliography, the pages that follow will tell you where and how to find reliable information covering virtually all topics related to hepatitis B, from the essentials to the most advanced areas of research. Public, academic, government, and peer-reviewed research studies are emphasized. Various abstracts are reproduced to give you some of the latest official information available to date on hepatitis B. Abundant guidance is given on how to obtain free-of-charge primary research results via the Internet. While this book focuses on the field of medicine, when some sources provide access to non-medical information relating to hepatitis B, these are noted in the text. E-book and electronic versions of this book are fully interactive with each of the Internet sites mentioned (clicking on a hyperlink automatically opens your browser to the site indicated). If you are using the hard copy version of this book, you can access a cited Web site by typing the provided Web address directly into your Internet browser. You may find it useful to refer to synonyms or related terms when accessing these Internet databases. NOTE: At the time of publication, the Web addresses were functional. However, some links may fail due to URL address changes, which is a common occurrence on the Internet. For readers unfamiliar with the Internet, detailed instructions are offered on how to access electronic resources. For readers unfamiliar with medical terminology, a comprehensive glossary is provided. For readers without access to Internet resources, a directory of medical libraries, that have or can locate references cited here, is given. We hope these resources will prove useful to the widest possible audience seeking information on hepatitis B. The Editors

CHAPTER 1. STUDIES ON HEPATITIS B Overview In this chapter, we will show you how to locate peer-reviewed references and studies on hepatitis B.

The Combined Health Information Database The Combined Health Information Database summarizes studies across numerous federal agencies. To limit your investigation to research studies and hepatitis B, you will need to use the advanced search options. First, go to http://chid.nih.gov/index.html. From there, select the “Detailed Search” option (or go directly to that page with the following hyperlink: http://chid.nih.gov/detail/detail.html). The trick in extracting studies is found in the drop boxes at the bottom of the search page where “You may refine your search by.” Select the dates and language you prefer, and the format option “Journal Article.” At the top of the search form, select the number of records you would like to see (we recommend 100) and check the box to display “whole records.” We recommend that you type “hepatitis B” (or synonyms) into the “For these words:” box. Consider using the option “anywhere in record” to make your search as broad as possible. If you want to limit the search to only a particular field, such as the title of the journal, then select this option in the “Search in these fields” drop box. The following is what you can expect from this type of search: •

Website: www.blackwell-science.com. Summary: Acute and chronic infections with hepatitis B virus (HBV) are a major public health problem in Australia and New Zealand. This article reviews the treatment of chronic hepatitis B in these countries. Although both countries have a low prevalence of the population with chronic HBV (less than 2 percent) infection, both have certain population groups with a high prevalence of the disease. In Australia, the highest rates

are found among Aborigines and Torres Strait Islanders (approximately 10 to 25 percent) and immigrants from Southeast Asia and the Pacific Islands (5 to 15 percent). In New Zealand the cases of chronic HBV infection vary among groups: Chinese (10 percent), Maori (5.43 percent), Pacific Islanders (4.4 percent) and Europeans (0.43 percent). In New Zealand, a universal vaccination program was introduced, with hepatitis B vaccine being incorporated into the national childhood vaccination schedule in 1988. In both New Zealand and Australia, pregnant women are screened and HBV vaccine is administered to children of chronically infected mothers. Seronegative household members of families containing a member found to be acutely or chronically infected with HBV are vaccinated. Interferon therapy has been available since the late 1980s and is fully subsidized. Lamivudine has been prescribe preliver and postliver transplant as part of an international compassionate use program. Interferon, usually without steroid priming, has been the standard therapy, with trials showing a 41 percent response rate. 26 references. •

Hepatitis B Vaccine Recommended for All Children Source: FDA Consumer. 25(5): 2-3. June 1991. Summary: All children should be vaccinated against hepatitis B, according to the Immunization Practices Advisory Committee of the U.S. Public Health Service. Immunization experts made this recommendation in February 1991, after strategies to vaccinate adults at high risk for hepatitis B failed to achieve sufficient coverage. This brief article reviews the reasons behind this decision and the potential benefits of universal immunization. 2 references. (AA-M).

Summary: An estimated 200,000 to 300,000 people in the US become infected each year with the hepatitis B virus, and 150,000 become infected with the hepatitis C virus. Identification of the modes of transmission is of primary importance in efforts to curtail the spread of these infections. This article reviews the risk factors, both common and rare, that have been identified to date. The authors note that, in individual cases, knowledge of risk factors for transmission helps physicians to identify and counsel patients at risk, to identify those whose history indicates the possibility of infection, and, for those who are seropositive, to determine how and when infection occurred, which may have implications for prognosis and treatment. Topics include sexual contact, household and other social contacts, risks of HBV transmission in institutional settings, the maternal-fetal interface, blood and blood product transfusions, hemodialysis, transplantation associated risk, physicians as a risk to their patients, transmission from medical devices, occupational risk factors, social and recreational transmission, intravenous drug abuse, cosmetic transmission (ear piercing, tattooing, barber shop shaving, manicurists), the risk factor associated with certain sports, and insect-borne infection. 2 figures. 4 tables. 28 references.

Summary: Because of exposure to blood-borne pathogens and potentially infectious materials, athletic training is an allied health care profession with an increased risk of exposure to hepatitis B virus (HBV). This article considers the prevention of HBV in athletic training. Topics include the pathogenesis and epidemiology of HBV; signs and symptoms; transmission; and preventive measures, including immunization, protective equipment, housekeeping, and sharps. The authors stress the importance of information dissemination about prevention of HBV in the athletic training setting to all athletic training staff and students, through in-service training sessions, symposia, and lectures. 1 table. 11 references.

Management of Patients with Chronic Hepatitis B Source: Journal of Gastroenterology and Hepatology. 17(4): 406-408. April 2002. Contact: Available from Blackwell Science. 54 University Street, Carlton South 3053, Victoria, Australia. +61393470300. Fax +61393475001. E-mail: [email protected]. Website: www.blackwell-science.com. Summary: Better understanding of hepatitis B virus (HBV) replication and the natural history and immunopathogenesis of chronic hepatitis B, together with the introduction of effective agents with different mechanisms of action, are the basis for better therapeutic strategies against chronic hepatitis B. This article brings readers up to date on the current management of patients with chronic hepatitis B. Among currently available drugs, alpha interferon therapy gives a response rate of 30 to 40 percent, compared with 10 to 20 percent in matched controls, but patients with lower alanine aminotransferase (ALT), higher HBV-DNA, and immunosuppressed patients have a poorer response, and alpha interference can be dangerous in patients with cirrhosis (liver scarring). The author also reports on the use of thymosin alpha 1, lamivudine, and other drugs still in preliminary trials (adefovir dipivoxil, entecavir, emtricitabine, clevudine). The author concludes that further development of new drugs and new strategies, such as combination or sequential therapy, may help to better achieve the goals of treatment for chronic hepatitis B in the future. 1 table. 10 references.

Prophylactic Lamivudine Prevents Hepatitis B Reactivation in Chemotherapy Patients Source: Alimentary Pharmacology and Therapeutics. 16(11): 1939-1944. November 2002. Contact: Available from Alimentary Pharmacology and Therapeutics. Blackwell Science Ltd., Osney Mead, Oxford OX2 OEL, UK. +44(0)1865 206206. Fax +44(0)1865 721205. Email: [email protected]. Website: www.blackwell-science.com. Summary: Chronic hepatitis B virus (HBV) carriers receiving chemotherapy develop a high hepatitis B virus reactivation rate (38 to 53 percent) with a high mortality (37 to 60 percent). Few studies have characterized the efficacy of lamivudine in the treatment of chemotherapy-induced HBV reactivation. This article reports on a study undertaken to determine whether lamivudine prophylaxis reduces chemotherapy-induced HBV reactivation and mortality. The medical records of all hepatitis B surface antigenpositive patients with malignancy treated with chemotherapy since 1995 at the National University Hospital of Singapore were identified and divided into those who received lamivudine prophylaxis before chemotherapy (P, n = 16) and those who did not (NP, n = 19). The baseline characteristics of the two groups were similar. Seven of the 19 patients in the NP group and none of the 16 patients in the P group developed HBV reactivation (36.8 percent versus 0 percent). Six of the seven patients in the NP group who developed reactivation received lamivudine at that time, but five died (mortality, 71.4 percent),

whilst no patient in the P group died from reactivation. The authors conclude that prophylactic lamivudine appears to prevent hepatitis B virus reactivation and its associated mortality in patients treated with chemotherapy. 3 tables. 11 references. •

Adding to the Hepatitis B Virus Treatment Arsenal: Glucosidase Inhibitor Derivatives (editorial) Source: Hepatology. 33(6): 1544-1546. June 2001. Contact: Available from W.B. Saunders Company. 6277 Sea Harbor Drive, Orlando, FL 19106-3399. (800) 654-2452 or (407) 345-4000. Summary: Chronic hepatitis B virus (HBV) infection is a major cause of cirrhosis (scarring) and hepatocellular carcinoma (liver cancer) in the United States and worldwide. Eradication of the infection and prevention of complications of chronic infection are the dual goals of treatment. This editorial comments on an accompanying article which reports on the use of alfa glucosidase inhibitor derivatives in the drug therapy for HBV infections. The agents under consideration (N nonyl DNJ and N nonyl DGJ) appear to have a mechanism of action that is unique and potentially complementary to that of nucleoside analogues. As new agents for treatment of HBV infection become available for clinical use, combination treatment of chronic HBV infection can be anticipated. The editorial stresses that designing the optimal combination therapy for HBV will need to take into account drug potency, mechanism of drug uptake and activation, sites of drug action, effect on cccDNA, and specific viral mutations arising with prolonged therapy. The author concludes that it remains to be seen whether these imino sugars (N nonyl DNJ and N nonyl DGJ) will join the growing list of anti HBV drugs. However, if the present results can be reproduced in animal studies and clinical trials (with humans), this novel class of agents may be a welcome addition to the arsenal of anti HBV drugs. 1 figure. 1 table. 13 references.

Hepatitis B and C: Looking Beyond Traditional Therapy Source: Digestive Health and Nutrition. p. 23-25. November-December 2000. Contact: Available from American Gastroenterological Association. 7910 Woodmont Avenue, 7th Floor, Bethesda, MD 20814. (877) DHN-4YOU or (301) 654-2055, ext. 650. Email: [email protected]. Summary: For years, both hepatitis B and C have been treated mainly with one drug, interferon, that can cause a host of side effects and helps less than 50 percent of the people who take it. This article describes research into new drugs that indicates that many people with hepatitis C who do not respond to interferon alone may respond when it is combined with other drugs, and that some drugs may even take the place of interferon entirely for the treatment of hepatitis B. The author briefly reviews the different types of hepatitis, then notes the symptoms of hepatitis B and C, how they are transmitted, and prevention strategies. The author then focuses on interferon therapy. Interferon is a natural substance produced by the body to protect itself against infection, but, when infected with hepatitis, the body may not make enough interferon to fight the disease effectively. Injections of artificial interferon help stimulate the immune system to fight hepatitis. The author then describes the use of Rebetron (the trade name for a drug that combines interferon and ribavirin). Alone, ribavirin does not have much antiviral action, however, when taken with interferon, ribavirin boosts sustained response rates in hepatitis C patients to 40 percent. There are considerable side effects, so each patient must be cared for on an individualized plan. The article also describes the use of a modified form of interferon (pegylated interferon) which is expected to be approved by

the Food and Drug Administration (FDA) in 2001 for treatment of hepatitis C (and perhaps later for hepatitis B). Another drug discussed is lamivudine, used to stop hepatitis B virus from reproducing. A final section discusses the role of some of these drugs in helping patients wait longer for a liver transplant. One sidebar reviews the impact of hepatitis on the liver and why it is so important to treat the disease when possible. •

New Treatment Strategies in Hepatitis B and C: Natural History of Chronic Hepatitis B and C Source: Journal of Gastroenterology and Hepatology. 14(Supplement): S1-S5. May 1999. Contact: Available from Blackwell Science. 54 University Street, Carlton South 3053, Victoria, Australia. +61393470300. Fax +61393475001. E-mail: [email protected]. Website: www.blackwell-science.com. Summary: Hepatitis B virus (HBV) affects more than 300 million individuals worldwide, and in the United States approximately 1.25 million individuals are chronic carriers of HBV. This article reviews the natural history of chronic hepatitis B and C. The risk of becoming a chronic hepatitis B virus surface antigen carrier is dependent upon the mode of acquisition of infection as well as the age of the individual at the time of infection. For those individuals with high levels of virus replication, chronic active hepatitis (CAV) with progression to cirrhosis, liver failure and hepatocellular carcinoma (HCC, liver cancer) is common. Liver transplantation is an excellent treatment option for patients with end stage liver disease from HBV. Patients with chronic HBV infection should be screened periodically for hepatoma, although screening strategies have not been proven to prolong survival. Newer antiviral agents for the treatment of HBV are potent inhibitors of HBV DNA and their long term effect on the natural history of HBV is yet to be proven. The natural history of hepatitis C virus (HCV) infection is less well defined than that of chronic HBV. Certain patients who are chronic carriers of HCV may never develop extensive fibrosis, whereas others will progress to CAV with cirrhosis, HCC, and end stage liver disease. Factors that influence the progression of HCV are those related to the host, including the age at acquisition of infection, gender, and immune status; the disease process is accelerated in patients who consume regular amounts of alcohol. Hepatocellular carcinoma develops frequently in patients with HCV infection and its overall incidence is increasing due to this chronic viral disease. Patients with HCV cirrhosis should be screened regularly for hepatoma and liver transplantation is an effective treatment option for those with end stage disease. The author concludes that the impact of antiviral therapy on the natural history of HCV is still to be determined and should be the focus of large clinical trials. 4 tables. 30 references.

percent of the infants of hepatitis B e antigen (HBeAg) seropositive mothers become hepatitis B surface antigen (HBsAg) carriers. Children chronically infected are mostly asymptomatic. Although liver damage is usually mild during childhood, severe liver disease, including cirrhosis and hepatocellular carcinoma, may develop insidiously for 2 to 7 years. Spontaneous HBeAg seroconversion occurs gradually as the age of the child increases. Viral replication is reduced during this process, which is usually preceded by an elevation of aminotransferases. In a long term followup study, the annual HBeAg seroconversion rate was 4 to 5 percent in children older than 3 years of age and less than 2 percent in children under 3 years. The annual seroconversion rate was very low (0.56 percent). Age at infection, maternal HBeAg and HBeAg status, host immune status, and possibly the HBV strain are the main factors determining the course of HBV infection in children. 22 references. •

Website: www.blackwell-science.com. Summary: Hepatitis B virus (HBV) infection is a major health burden in the Asia-Pacific region. This article addresses the treatment of chronic hepatitis B, focusing on case selection and duration of therapy. The author stresses that proper assessment and judicial introduction of therapy can suppress replication of HBV and resolve liver inflammation, thereby preventing the silent progression of chronic liver disease to end stage cirrhosis (liver scarring). The author discusses interferon (IFN) monotherapy, injection based therapies, lamivudine, administration and dosage, patient response, drug resistant mutations, the end point of treatment, combination therapy, herbal medicines, and patient indications for different drug therapies. The author concludes that preliminary data from IFN and lamivudine combination therapy show some promise, but there are conflicting results.

Occult Hepatitis B Virus Infection in Patients with Chronic Hepatitis C Liver Disease Source: New England Journal of Medicine. 341(1): 22-26. July 1, 1999. Summary: Hepatitis B virus (HBV) infections in patients who lack detectable hepatitis B surface antigen (HBsAg) are called occult infections. Although such infections have been identified in patients with chronic hepatitis C liver disease, their prevalence and clinical significance are not known. This article reports on a study that searched for HBV DNA in liver and serum samples from 200 HBsAg negative patients with hepatitis C virus (HCV) liver disease (147 with chronic hepatitis, 48 with cirrhosis, and 5 with minimal histologic changes). Of the patients, 100 had detectable antibodies to the HBV core antigen; 100 were negative for all HBV markers. Some patients (n = 83) were treated with interferon alfa. The study also included 50 patients with liver disease who were negative both for HBsAg and for HCV markers. Sixty six of the 200 patients with chronic hepatitis C liver disease (33 percent) had HBV sequences, as did 7 of the 50 patients with liver disease unrelated to hepatitis C. Among the 66 patients, 46 were anti HBc positive and 20 were negative for all HBV markers. Twenty two of these 66 patients (33 percent) had cirrhosis, as compared with 26 of the 134 patients with hepatitis C infection but no HBV sequences (19 percent). HBV sequences were detected in 26 of the 55 patients in whom interferon therapy was ineffective and 7 of the 28 patients in whom interferon therapy was effective.

Hepatic Failure and Lactic Acidosis Due to Fialuridine (FIAU), an Investigational Nucleoside Analogue for Chronic Hepatitis B Source: New England Journal of Medicine. 333(17): 1099-1105. October 26, 1995. Summary: In this article, the authors describe severe and unexpected multisystem toxicity that occurred during a study of the antiviral nucleoside analogue fialuridine (FIAU) as therapy for chronic hepatitis B virus infection. Fifteen patients with chronic hepatitis B were randomly assigned to receive fialuridine at a dose of either 0.10 or 0.25 mg per kilogram of body weight per day for 24 weeks. They were monitored every 1 to 2 weeks by means of a physical examination, blood tests, and testing for hepatitis B virus markers. During the 13th week, lactic acidosis and liver failure suddenly developed in 1 patient. The study was terminated on an emergency basis, and all treatment with fialuridine was discontinued. Seven patients were found to have severe hepatotoxicity, with progressive lactic acidosis, worsening jaundice, and deteriorating hepatic synthetic function, despite the discontinuation of fialuridine. Of these seven patients, five died and two survived after liver transplantation. The authors conclude that the toxic reaction was probably caused by widespread mitochondrial damage and may occur infrequently with other nucleoside analogues. 5 figures. 1 table. 43 references.

Summary: In this article, the authors report on the result of a study aimed at assessing the variability of assumptions upon which economic models for the introduction of vaccination against hepatitis B are based. They discuss the conclusions reached and define a minimum set of methodological standards upon which future economic studies on vaccines should be based. The literature review identified 116 published and unpublished works by Medline literature searches, consulting private databases, and corresponding with all authors and researchers active in the economic evaluation of vaccines. All works were assessed, but only the 90 studies that were original economic analyses are reviewed. The authors found profound variability on main parameters of the efficiency equation, including disease incidence, costing methods, use of marginal theory, discounting and study timespan, sensitivity analysis, and reporting methods.

Hampering Hepatitis B Transmission Through Neonatal Therapy Source: National Medical Association News. May-June 1992. p. 3. Summary: In this interview article, Dr. Neil S. Silverman explains his views on hampering hepatitis B transmission through neonatal therapy. He proposes drug screening as a marker for increased risk of HBsAg positivity and empiric initiation of hepatitis B immune globulin (HBIG) prophylaxis for infants born to unregistered women with positive results of urine drug screening whose infants' HBsAg results are unavailable within 12 hours of delivery. In this interview, Dr. Silverman discusses the relationship between hepatitis B prevalence and the unregistered prenatal population; the incidence of hepatitis B in the population of women that use drugs; problems with legalities of a drug screening policy; specific advantages of prenatal testing; risks involved with immunoglobulin administration; statistics on the proposed numbers of hepatitis B cases that could be prevented annually; morbidity for children who become hepatitis carriers; the likelihood of a plan for hepatitis B prophylaxis being implemented; and problems created by the ongoing and increasing substance abuse situation.

Summary: Infection with hepatitis B virus (HBV) leads to a wide spectrum of liver injury. Fulminant hepatitis B is a rare disease, but carries a high mortality. This brief article reports on a nosocomial outbreak of five cases of fulminant hepatitis B that occurred in Israel. Investigations by the author suggest that the five patients with fulminant hepatitis were infected by the same virus derived from a common source while a subclinical case was infected by another HBV strain at the same time. This study points to a role for naturally occurring viral mutations in the emergence of HBV viral strains capable of producing more severe liver injury.

Contact: Available from Journals Subscriptions Department, Harcourt Brace and Company Ltd. High Street, Foots Cray, Sidcup, Kent DA14 5HP UK. Telephone +181 300 3322. Summary: Infections by hepatitis B virus (HBV) continue to be a major source of chronic liver disease, despite the great advancements in our understanding of HBV infections and the widespread availability of an effective vaccine. Once a patient has become chronically infected with HBV, the currently available therapies are not particularly effective, and there is a high risk that infection will proceed to cirrhosis and hepatocellular carcinoma. This article evaluates the potential of a novel therapy: the application of modified forms of hepatitis delta virus (HDV) as part of an antiviral strategy for individuals with chronic hepatitis B virus infections. 3 figures. 31 references.

Clinical Trial of Lamivudine in Children with Chronic Hepatitis B Source: New England Journal of Medicine. NEJM. 346(22): 1706-1713. May 30, 2002. Summary: Lamivudine therapy is effective for chronic hepatitis B virus (HBV) infection in adults. This article reports on a study that evaluated the efficacy and tolerability of lamivudine as a treatment for chronic infection with HBV in children. Of the 403 children screened, 191 were randomly assigned to receive lamivudine and 97 to receive placebo. The rate of virologic response at week 52 was higher among children who received lamivudine than among those who received placebo (23 percent versus 13 percent). Lamivudine therapy was well tolerated and was also associated with higher rates of seroconversion from hepatitis B e antigen (HBeAg) to hepatitis B e antibody, normalization of alanine aminotransferase levels, and suppression of HBV DNA. 2 figures. 4 tables. 20 references.

Review: Hepatitis B and Liver Transplantation Source: Journal of Gastroenterology and Hepatology. 13(3): 217-223. March 1997. Contact: Available from Blackwell Science Pty Ltd. P.O.

Summary: Liver transplantation in hepatitis B virus (HBV) infected patients is very commonly followed by recurrence of infection in the transplanted liver. This review article focuses on new strategies for the prevention and treatment of disease recurrence after transplantation. Most recipients with HBV recurrence will develop chronic hepatitis that follows a more aggressive course than is seen in nonimmunocompromised subjects; this frequently results in graft failure. The presence of hepatitis B e antigen or significant levels of HBV-DNA in the serum is highly predictive of recurrence and this has led to the view that patients, whose serum is positive for these conventional markers of replication, should be excluded from transplantation. The key to improving the results of transplantation in patients with HBV infection lies in the development of effective strategies to prevent reinfection. High dose anti-HBs immunoglobulin is effective in patients who are coinfected with hepatitis D, those transplanted for fulminant hepatitis, and cirrhotic patients who have very low levels of viral replication prior to transplantation. Unfortunately, immunoprophylaxis does not seem to influence the outcome in those patients with higher levels of replication. There are several new orally active nucleoside analogues that are potent inhibitors of hepatitis B replication that may be effective for both the prevention and treatment of recurrent disease. The most promising are lamivudine and famciclovir. Both agents have been extensively evaluated in animal models of HBV and have been shown to rapidly suppress viral replication. The author concludes that the initial experience with these agents in liver transplant recipients has been promising and a number of studies are currently under way to determine whether these drugs, used alone or in combination with immunoprophylaxis, are able to prevent recurrence in those patients at highest risk of posttransplant HBV recurrence. 1 table. 59 references.

Website: www.blackwell-science.com. Summary: Non-response to interferon (IFN) monotherapy is a major therapeutic problem in the management of chronic hepatitis B virus (HBV) infection. This article reports on a study in which the effectiveness of combination therapy to enhance the immunomodulatory effect of IFN by combining GMCSF (granulocyte-macrophage colony stimulating factor) or decreasing viral load by adding an antiviral agent such as lamivudine was evaluated prospectively. The study included 24 patients with chronic hepatitis B who were non-responders to previous IFN therapy were randomized to receive an IFN and GMCSF (group A, n = 10) or IFN and lamivudine (group B, n = 14) combination for 6 months. All patients successfully completed both the treatment schedules. At the end of treatment, there was a significant decrease in mean ALT levels. The HBV-DNA and HBeAg loss was seen in six of 10 (60 percent) patients in group ! and seven of 15 (50 percent) patients in group B. During follow up, two of six patients (33 percent) in group A and three of seven (43 percent) patients in group B relapsed with HBV-DNA and HBeAg positivity, which meant an overall sustained response of 40 percent and 28 percent respectively. None of the factors such as HBV viral load, ALT levels or liver histology could predict the non-response to combination therapy or occurrence of relapse. The authors conclude that larger studies using such combination therapies would be helpful in improving treatment strategies for chronic hepatitis B. 4 tables. 34 references. •

Saunders Company. 6277 Sea Harbor Drive, Orlando, FL 19106-3399. (800) 654-2452 or (407) 345-4000. Summary: Occult (hidden) hepatitis B virus (HBV) infection has been reported in 30 to 50 percent of patients with acute liver failure (ALF) in small case series. This article reports on a study undertaken to determine the prevalence of occult HBV infection in a large series of ALF patients in the United States and the prevalence of precore and core promoter variants in patients with ALF caused by hepatitis B. Sera (blood products) from patients in the US ALF study and liver, when available, were tested using nested polymerase chain reaction (PCR) with primers in the HBV S and precore regions. PCR positive samples were sequenced. Sera and or liver from 139 patients (39 males, 100 females; mean age 42 years) were studied between January 1998 and December 1999. Twelve patients were diagnosed with hepatitis B, one with hepatitis B, C, and D coinfection, and 22 had indeterminate etiology (cause). HBV DNA was detected in the sera of 9 patients (6 percent); all 9 had ALF caused by hepatitis B. HBV genotypes A, B, C, and D were present in 4, 3, 1, and 1 patients, respectively. Seven of these 9 patients had precore or core promoter variants. Liver from 19 patients were examined. HBV DNA was detected in the liver of 3 patients with ALF caused by hepatitis B, but in none of the remaining 16 patients with non B ALF. Contrary to earlier reports, occult HBV infection was not present in this large series of ALF patients in the United States. 1 appendix. 3 tables. 34 references.

Website: www.blackwell-science.com. Summary: Of the estimated 50 million new cases of hepatitis B virus (HBV) infection diagnosed annually, 5 to 10 percent of adults and up to 90 percent of infants will become chronically infected. Of those who become chronically infected, 75 percent are in Asia where hepatitis B is the leading cause of chronic hepatitis (liver infection), cirrhosis (liver scarring), and hepatocellular carcinoma (liver cancer). This article offers detailed statistics on chronic HBV infection in Asian countries, including Indonesia, the Phillipines, Thailand, China, Taiwan, and Malaysia. In the highly endemic countries in Asia (places where HBV is found on a routine basis in the population), the majority of infections are contracted postnatally or perinatally (during birth). Three phases of chronic HBV infection are recognized: phase 1 patients are HBeAg positive with high levels of virus in the serum (blood) and minimal hepatic (liver) inflammation; phase 2 patients have intermittent or continuous hepatitis of varying degrees of severity; phase 3 is the inactive phase during which viral concentrations are low and there is minimal inflammatory activity in the liver. In general, patients who clear HBeAg have a better prognosis than patients who remain HBeAg positive for prolonged periods of time. The outcome after anti HBe seroconversion depends on the degree of preexisting liver damage and any subsequent HBV reactivation. Without preexisting cirrhosis, there may be only slight fibrosis or mild chronic hepatitis, but with preexisting cirrhosis, further complications may happen. The annual incidence of hepatic decompensation (reduction in liver function) in HBV related cirrhosis varies from 2 to 10 percent and in these patients, the 5 year survival rate drops dramatically to 14 to 35 percent. The annual risk of developing HCC (liver cancer) in patients with cirrhosis varies between 1 and 6 percent. Chronic hepatitis B is not a static disease and the natural history of the disease is affected by both viral and host factors. The prognosis is poor with decompensated cirrhosis and effective treatment options are limited. The authors conclude that prevention of HBV infection through vaccination is still therefore the best strategy for decreasing the incidence of hepatitis B associated cirrhosis and HCC. 1 table. 32 references. •

Hepatitis B Virus Infection Without Immunological Markers After Open-Heart Surgery Source: Lancet. 345(8946): 355-357. February 11, 1995. Summary: Posttransfusion hepatitis is still an important problem, despite the screening of blood donors for hepatitis B virus (HBV) and hepatitis C virus infections. This article reports on a study in which the researchers assessed whether HBV DNA might be detected by PCR in prospectively collected serum samples of patients with unexplained posttransfusion hepatitis but no immunological HBV markers. They found HBV DNA in 4 (20 percent) of 20 patients with unexplained posttransfusion hepatitis and in 5 patients with mildly increased aminotransferases. The clinical course of these HBV infections was usually mild and self-limiting. The researchers conclude that low-titre, immunologically negative HBV infections do exist and might represent a significant cause of post-transfusion hepatitis.

Summary: Reported rates of acute hepatitis B are high in many former Soviet Union republics and modes of transmission are not well defined. This article reports on two case control studies that were undertaken in Moldova to identify risk factors for acute hepatitis B in people aged 2 to 15 years (children) and older than 15 years (adults). Serologically confirmed acute hepatitis B cases occurring between January 1994 and August 1995 were matched on age, sex, and district of residence to three potential control groups who were tested for hepatitis B markers to exclude the immune. In multivariate analysis, compared with the 175 controls, the 70 adult cases (mean age 25 years, 66 percent male) were more likely to report receiving injections in the 6 months before illness during a dental visit, a hospital visit, or a visit to the polyclinic. Among children, receiving injections during a hospital visit was the only exposure reported significantly more often by the 19 cases (mean age 8 years, 68 percent male) compared with the 81 controls. These results, along with reported unsafe injection practices in Moldova, suggest that injections are a major source of hepatitis B virus transmission and highlight the importance of proper infection control procedures in preventing transmission of blood borne infections. 3 tables. 25 references. •

Summary: Since the publication of the last extensive review of hepatitis vaccines, use of inactivated hepatitis A vaccines has been extended to high-risk regions of the United States and specific patient groups, such as those with chronic liver disease, and use of the recombinant hepatitis B vaccines has been recommended for older adolescents. In addition, a combination hepatitis A and B vaccine, recently approved for licensure by the U.S. Food and Drug Administration (FDA), should increase convenience and compliance, reduce the costs of vaccination, and provide prolonged and dual protection for those at risk for hepatitis. This article considers these advances and their use for immunoprophylaxis. The author also briefly comments that although commercially available vaccines for hepatitis C, D, and E remain a distant goal, advances in vaccine and adjuvant technology, including immunization with DNA-based vaccines, hold promise for the future. 5 tables. 85 references.

polio vaccine, 1 dose of measles containing vaccine, and 3 doses of Haemophilus influenzae type b vaccine). The study included an analysis of data from the 1998 National Immunization Survey, a random digit dialing telephone survey (n = 34,480 complete interviews) of parents of children aged 19 to 35 months from 50 states and 28 selected urban areas in the United States that included a provider record check mail survey. Overall, 86.9 percent of children 19 to 35 months of age in 1998 received 3 or more doses of hepatitis B vaccine, and 79.9 percent completed the 4:3:1:3 vaccine series. Analysis indicated that, compared with children who received the first hepatitis B vaccine dose within 7 days of birth, odds ratios for not completing the 3 dose hepatitis B vaccine series increased as the time from birth increased. The authors hypothesize that the significant association between age at administration of the first dose of hepatitis B vaccine and completion of the 3 dose series may reflect clinician concerns about parental resistance to multiple injections during a single visit. The authors conclude that administration of the first dose of hepatitis B vaccine at birth is associated with increased likelihood of completion of the hepatitis B vaccination series. Because of this and other advantages, providers should strongly consider a hepatitis B vaccination schedule that initiates vaccination at birth. 1 figure. 2 tables. 23 references. •

Website: www.blackwell-science.com. Summary: The clinical outcomes of adult acquired acute infection of hepatitis C virus (HCV) and hepatitis B virus (HBV) are quite different. This article reports on a comparison of clinical, biochemical, virologic, and pathologic pictures in 22 adults patients with acute hepatitis C and 16 adult patients with acute hepatitis B. Liver biopsies were performed within 3 months of acute onset of the illness in each of these patients. The results showed that a significantly younger age; a higher ratio of the clinical symptoms of jaundice, nausea, vomiting, and poor appetite; a higher mean serum (blood) level of alanine transaminase; aspartate transaminase, and total bilirubin were present in patients with acute hepatitis B, compared to those with acute hepatitis C. There was a significantly higher degree of periportal inflammation and total necroinflammatory activity in the acute hepatitis B patients. Fifteen (68.2 percent) of the 22 patients with acute hepatitis C had detectable serum HCV RNA, but only two (14.3 percent) of the 14 tested patients with acute hepatitis B had detectable serum HCV DNA, detected by using the branched DNA signal amplification assay. Eighteen (82 percent) of the 22 acute hepatitis C patients and none of the 16 acute hepatitis B patients progressed into a chronic hepatitis stage. 3 tables. 35 references.

Summary: The development of hepatitis vaccines in the 1980s has substantially decreased dental workers' risk of acquiring hepatitis B virus (HBV). This article reports on hepatitis B immunization and postimmunization serology, focusing on dental workers in Canada. A recent survey of dentists in Canada showed that more than 90

percent had completed an immunization series and an additional 3 percent had natural immunity. However, rates of immunization among dental assistants and hygienists was found to be much lower. The author discusses the vaccines themselves, the antibody levels required for protection, postimmunization testing for immunity, and the potential need for booster doses of hepatitis B vaccine. The author concludes that all nonimmune dental health care workers should receive immunization with recombinant hepatitis B vaccine. Postimmunization serology should be performed to ensure seroconversion and guide further immunization and postexposure prophylaxis. Following seroconversion, booster doses of vaccine are not required. 10 references. •

Saunders Company. 6277 Sea Harbor Drive, Orlando, FL 19106-3399. (800) 654-2452 or (407) 345-4000. Summary: The impact of hepatitis B (HBV) and C (HCV) on patient survival after kidney transplantation is controversial. This article reports on a study undertaken to assess the independent prognostic values of hepatitis B surface antigen (HBsAg) and anti-HCV in a large renal transplant population. The study also compared infected and noninfected patients matched for factors possibly associated with graft and patient survival and assessed the prognostic value of biopsy proven cirrhosis. A total of 834 transplanted patients were included: 128 with positive HBsAg (group I), 216 with positive anti-HCV (group II), and 490 without serological markers of HBV and HCV (group III). Fifteen percent of patients were HBsAg positive, and 29 percent were antiHCV positive. Ten year survival of group I (55 percent) and group II (65 percent) were significantly lower than survival of group III (80 percent). At 10 years, among all 834 patients, 4 variables had independent prognostic values in patient survival: age at transplantation, year of transplantation, biopsy proven cirrhosis, and presence of HCV antibodies. In the case control study, comparison of infected patients with their matched controls showed that age at transplantation and anti-HCV were independent prognostic factors. HCV, biopsy proven cirrhosis, and age are independent prognostic factors of 10 year survival in patients with kidney grafts. The authors conclude that a routine liver histological analysis in infected patients would improve selection of patients for renal transplantation. 4 figures. 5 tables. 34 references. (AA-M).

Benefit-Cost Analysis of Hepatitis B Vaccine Programs for Occupationally Exposed Workers Source: Journal of Occupational Medicine. 33(6): 691-698. June 1991. Summary: The Occupational Safety and Health Administration proposed a vaccination program for workers exposed to the hepatitis B virus 12 or more times per year. This article reports on a benefit-cost analysis of the proposed regulation and an expanded rule that covers all at-risk workers, regardless of the number of exposures. The authors estimated the dollar benefit of the program using two methods. The first estimates the avoided cost of medical care, prophylaxis, and lost productivity at $124 million annually. The second approach includes the value of avoided pain and suffering from hepatitis B, thus increasing the total dollar benefit to $679 million. Although both methods indicate benefits are greater than program costs, the valuation of avoided pain and suffering substantially increases net benefits. Furthermore, providing the vaccine to all exposed workers is cost-effective if one or more cases of hepatitis B are avoided per 6500 workers annually. 1 figure. 7 tables. 12 references. (AA).

Journals Subscriptions Department, High Street, Foots Cray, Sidcup, Kent DA14 5HP UK. Telephone +181 300 3322. Summary: The World Health Organization estimates that about 350 million chronic carriers of hepatitis B exist worldwide; many carriers develop cirrhosis (liver scarring) or hepatocellular carcinoma (HCC, liver cancer) over the course of their lives. Although infection poses a substantial public health burden in many parts of the world, the magnitude of this burden is often unclear (because available information is not readily accessible). This report summarizes the available information from multiple sources for two geographic regions: Eastern Europe and the Middle East. To estimate the hepatitis B burden in the two regions, the authors collated existing information from published literature, organizations with health care data, the Internet, and the Global Burden of

Hepatitis B

Disease and Injury Series. Published literature provided the most extensive information about the occurrence of hepatitis B infection and was more available for Middle Eastern countries than for Eastern European countries. In both regions, most countries with prevalence data had an intermediate or high prevalence of carriers, but there was considerable heterogeneity within regions. Population subgroups within countries had different prevalences. Compared with the Middle East, relatively few Eastern European countries had infant immunization programs. The availability of information varies from country to country across the regions, and data comparisons are problematic. The low frequency of infant immunization programs in Eastern Europe constitutes an important missed opportunity for an effective public health intervention. Information about hepatitis B prevalence in population subgroups could be especially useful for identifying people who have the greatest need for intervention. 1 appendix. 2 figures. 4 tables. 69 references. •

HIV and Hepatitis B Infection and Risk Behavior in Young Gay and Bisexual Men Source: Public Health Reports; Vol. 112, March/April 1997. Contact: Boston University School of Public Health, Department of Epidemiology and Biostatistics, 80 East Concord St, Boston, MA, 02118, (617) 638-7718. Summary: This article describes a study conducted to estimate the prevalence of, and identify risks for, HIV type I (HIV-I) and hepatitis B virus (HBV) infections and unprotected anal intercourse among young homosexual and bisexual men. The authors performed a cross-sectional analysis of data from a prospective cohort of 508 gay and bisexual men aged 18-24. HIV-I seroprevalence was 2.4 percent with five of 390 college students and seven of 117 non-students infected. HIV-I infection was associated with having a history of a sexually transmitted disease (STD) other than HIV-I or hepatitis B. The prevalence of hepatitis B markers in unvaccinated men was 12.9 percent. This was significantly associated with Asian ethnicity, off-campus residence, and a history of an STD other than HIV-I or HBV. It was inversely associated with recent non-intravenous drug use. Eighteen percent of the participants reported having had sex with women during the previous 12 months, and 26.4 percent reported a history of unprotected anal intercourse during the previous 6 months. Men who reported unprotected anal intercourse were more likely to have a steady partner, to have met their partners in anonymous settings, and to be identified as probably alcohol-dependent. Although prevalence of HIV-I infection among young homosexual and bisexual men in Boston was relatively low, the high rates of unprotected anal intercourse suggest a potential for future HIV-I and HBV transmission. Interventions should focus on young men with histories of sexually transmitted diseases, alcohol abuse, and depression.

Family Physician Acceptance of Universal Hepatitis B Immunization of Infants Source: Journal of Family Practice. 36(2): 153-157. February 1993. Summary: This article describes a study that assessed the effectiveness of the Centers for Disease Control's (CDC) dissemination of a new immunization recommendation to family physicians; the effect of the new recommendation on clinical practice; and the degree to which noneconomic barriers may affect adoption of universal hepatitis B immunization. A random sample of 300 family physicians in North Carolina was surveyed by mail; a response rate of 78 percent was obtained. Overall, 48 percent of family physicians were aware of the new hepatitis B vaccine recommendation; however, only 17 percent agreed that it was warranted for all newborns in their practice. The authors conclude that the CDC does not have an effective mechanism for disseminating information to all physicians who care for children. Additionally, practical concerns of physicians and their patients regarding multiple injections and other practice-relevant issues must be considered when formulating new immunization recommendations. 4 tables. 6 references.

Hepatitis B Infection and Liver Transplantation Source: Canadian Journal of Gastroenterology. 11(5): 462-468. July-August 1997. Contact: Available from Pulsus Group, Inc. 2902 South Sheridan Way, Oakville, Ontario, Canada L6J 7L6. Summary: This article discusses liver transplantation in patients with hepatitis B. Patients with chronic hepatitis B virus (HBV) infection have historically high rates of allograft reinfection from extrahepatic (outside the liver) reservoirs of HBV, with worse long term outcome compared with that of transplant recipients without HBV infection. As a result, chronic HBV infection has been considered a contraindication for transplantation. However, prophylaxis against HBV recurrence, in the form of passive immunization with high dose hepatitis B hyperimmunoglobulin and the antiviral agent lamivudine, has recently been demonstrated to decrease the risk of reinfection. The author summarizes past experience and current status of HBV infection and transplantation, with emphasis on the issues surrounding prophylaxis. The author concludes that with appropriate prophylaxis, liver transplantation can be a viable proposition for patients with HBV infection. The main obstacles to high dose HBIG prophylaxis are the continued availability of the product, practicality of administration, and the cost and long term duration of treatment. 2 tables. 60 references.

Hepatitis B Virus Source: Scientific American. 264(4): 116-123. April 1991. Summary: This article discusses the hepatitis B virus (HBV) which causes liver diseases and a common form of cancer. During the past decade, evolving understanding of the molecular biology of HBV has found medical applications, particularly for preventing the infection. Mass vaccinations with the recombinant vaccine, the first vaccine for human use ever developed by recombinant DNA technology, will go far in controlling hepatitis B. The authors stress that such a campaign of vaccination would prevent not only the acute liver illness but also the associated cancer. This article emphasizes the epidemiology of hepatitis, the genetic structure and activity of HBV, and genetic engineering techniques used to develop a medical response to HBV. 6 figures. 5 references.

Treatment of Chronic Hepatitis B and Hepatitis C with Interferon Alfa-2b Source: American Family Physician. 54(5): 1598-1602. October 1996. Summary: This article discusses the treatment of chronic hepatitis B and hepatitis C with interferon alfa-2b. Interferon alfa-2b is the only agent currently approved by the U.S. Food and Drug Administration for the treatment of chronic hepatitis B and C. The authors note that initial enthusiasm for this therapy has waned with the realization that response rates are low and relapses are common. Recent studies, however, provide evidence of improved response rates with higher doses of interferon alfa-2b. Improved response is also being obtained with the use of interferon alfa-2b in combination with iron reduction therapy consisting of repeated phlebotomies. The research has enabled the identification of predictors of an increased likelihood of response to interferon alfa2b therapy. The application of these predictors to patient selection may improve the cost-benefit ratio for this treatment. Research data have documented a significant reduction in the cost of health care and an increased life expectancy with interferon alfa2b therapy in patients who have chronic hepatitis C, particularly young patients without fibrosis. A patient care algorithm for the management of chronic hepatitis C with interferon alfa-2b is provided. 1 figure. 22 references. (AA-M).

Summary: This article highlights four aspects of the natural history of chronic hepatitis B virus (HBV) infection that require clarification: the differences between Caucasians and Asians with chronic HBV infection; the relationship between HBeAg seroconversion and the onset of cirrhosis (liver scarring), the role of precore and core promoter mutations, and when patients develop hepatocellular carcinoma (HCC, or liver cancer) and other complications of cirrhosis. In chronic HBV infection acquired during adulthood, which is the type mostly seen in the Caucasian population, there is biochemical and histologic regression after HBeAg seroconversion, and the risk of death from hepatitis B related causes is low. In chronic HBV infection acquired during birth or early childhood, which is the type most commonly seen in the Asian population, there is a prolonged phases of immunotolerance. The immune clearance phase is characterized by multiple acute exacerbations preceded by elevations in serum HBV DNA levels, HBeAg concentration and HBeAg/anti HBe immune complexes. Of these patients, 2.4 percent may develop hepatic (liver) decompensation during the stage of HBeAg seroconversion. The development of cirrhosis occurs more frequently in patients with episodes of decompensation and with repeated severe acute exacerbations. However, progression to cirrhosis can be relatively silent and can occur even in children. After HBeAg seroconversion, precore and core promotor mutations occur frequently in the Asian population. However, there is little correlation between the occurrence of these mutations and alanine aminotransferase elevation in patients who are positive for anti HBe. Although cirrhosis develops during the process of HBeAg seroconversion, 68 percent of the complications of cirrhosis and of hepatocellular carcinoma occur after HBeAg seroconversion. These complications may still occur even after HBsAg seroclearance. 21 references. •

Nonresponders to Hepatitis B Vaccine Source: Postgraduate Medicine. 107(3): 97-98. March 2000. Contact: Available from McGraw-Hill, Inc. 1221 Avenue of the Americas, New York, NY 10020. (612) 832-7869. Summary: This article is one in a series of professional consultation clinical questions to which the author responds. In this article, the questioner notes that routine testing showed a health care worker in the clinic who was nonreactive for HbsAb (antibody to the hepatitis B surface antigen) after receiving the triple dose vaccine. The questioner asks for recommendations in handling this situation, both in regular daily settings and after a high risk exposure. The author replies by stating that treatment of health care workers who do not respond to hepatitis B vaccine is an important issue, because hepatitis B is the major infectious hazard among these personnel. Between 5 and 32 percent of people receiving the vaccine are nonresponders. The Centers for Disease Control (CDC) recommends that persons who do not respond to the initial vaccine series complete a second three dose series and get tested again. Current hepatitis B vaccines contain only recombinant HBsAg. However, a third generation hepatitis B vaccine is being reviewed for licensure that also contains proteins derived from the virus envelope. The author notes that this vaccine may offer an alternative for persons who do not respond to current vaccines. Some persons remain nonresponders, even to this new vaccine, suggesting that hepatitis B vaccine response may have a genetic basis. 1 reference.

Contact: Available from McGraw-Hill, Inc. 1221 Avenue of the Americas, New York, NY 10020. (612) 832-7869. Summary: This article is the third in a four article symposium that provides a practical approach to the diagnosis and management of common hepatic disorders encountered by primary care physicians. In this article, the author discusses current therapies for chronic hepatitis B and C and provides insight into future medications. Antiviral therapy in chronic hepatitis can completely eradicate the virus and induce remission of liver disease. To achieve such benefits, however, therapy should be initiated before decompensated liver disease ensues; at that point, liver transplantation is the only available option. The author describes indications for and contraindications to antiviral therapy in chronic hepatitis. For chronic HBV infection, interferon alfa2b requires only a 4 month course. However, it has adverse effects and contraindications and does not produce a universal response. Another option for HBV infection is lamivudine, which is administered orally and causes few side effects. However, relapse may occur when treatment is discontinued, and mutant virus may emerge. For chronic HCV infection, interferon alfa2a, interferon alfa2b, consensus interferon, and interferon combined with ribavirin have been used. The combination alternative is emerging as the method of choice in patients who do not have contraindications to oral ribavirin. Adverse effects are common and durability of response varies according to HCV RNA level and genotype. 5 tables. 21 references. •

Summary: This article reports on a project undertaken to determine the prevalence of hepatitis B markers and the compliance to hepatitis B vaccination at University Hospital of Santa Maria, Lisbon. The program was begun in 1989 for all hospital personnel and students of the medical school. The screening included 2,360 health care workers and 1,153 students: 57 percent of hospital personnel and 41 percent of medical students appeared for vaccination. The prevalence of hepatitis B markers was 16.8 percent for hospital personnel and 5.5 percent for students; 0.95 percent of the hospital personnel

and 0.3 percent of students were chronic carriers. The departments with the highest prevalence were the Biochemical Laboratory (7 out of 11 people, or 64 percent), Surgery (13 out of 31 people, 42 percent), Pulmonary (9 out of 23 people, 39 percent), Emergency (7 out of 24 people, 29 percent), Hematology Laboratory (7 out of 24 people, 29 percent), and Orthopedics (10 out of 35 people, 29 percent). The prevalence was higher in students in the last 3 years of medical school than those in the first 3 years (12.2 percent versus 7.2 percent, respectively). Adverse affects from vaccination occurred in 14.5 percent, with local pain the most frequent in 8.6 percent. The serologic efficacy was 95 percent. A nonresponse was observed in male workers: 13 percent compared with 5 percent for women. Older employees also showed higher nonresponse. The authors conclude that hepatitis B vaccination is safe and effective. This study shows the need for a more aggressive approach to the vaccination of health care workers because a significant percentage of them are not protected. 5 figures. 1 table. 32 references.

Prevalence of HIV, Hepatitis B, and Hepatitis C in People with Severe Mental Illness Source: American Journal of Public Health. 91(1): 31-37. January 2001.

Summary: This article reports on a study that assessed seroprevalence (as determined by blood test) of HIV, hepatitis B virus (HBV), and hepatitis C virus (HCV) among individuals with severe mental illness. Participants in the study (n = 913) were patients undergoing inpatient or outpatient treatment in Connecticut, Maryland, New Hampshire, or North Carolina. The prevalence of HIV infection in this sample (3.1 percent) was approximately 8 times that estimated in the United States population, but lower than rates reported in previous studies of people with severe mental illness. Prevalence rates of HBV (23.4 percent) and HCV (19.6 percent) were approximately 5 and 11 times the overall estimated population rates for these infections, respectively. Although routes of transmission were not ascertained in this study, the high rates of substance use disorder, particularly injection drug use among women, are likely to contribute to increased risk. The authors conclude that elevated rates of all three infections were found in this population. Of particular concern are the high rates of HCV infection, which are frequently undetected. Individuals with HCV infection commonly fail to receive appropriate treatment to limit liver damage and unknowingly may be a source of infection to others. Greater efforts at prevention, screening, and treatment for HIV, HBV, and HCV are important. There is a lack of information and concern about HCV on the part of both providers and patients with severe mental illness. For example, a great majority of clients in this study who were infected with HIV were aware of their condition, but most of those with HCV were not. Previous experience with this population suggests that a cornerstone of successful intervention will be integrated dual diagnosis in the context of intensive case management. 3 tables. 35 references.

infant hepatitis B vaccination. A questionnaire was mailed to 264 physicians providing obstetric services in San Francisco; of these, 113 were confirmed to be providing prenatal care and 76 obstetric providers returned completed questionnaires. Among these respondents, 79 percent believed that hepatitis B vaccine should be administered to all infants at birth, and 92 percent believed that it is feasible to educate all expectant mothers about infant hepatitis B vaccination. However, only 53 percent of respondents provided such education to all their pregnant patients. Only 23 percent provided education about other routine childhood immunizations. The authors conclude that obstetric providers in San Francisco are willing to educate pregnant patients about hepatitis B vaccination but are not always doing so. Providing education in a consistent manner may improve infant hepatitis B vaccination rates and may increase coverage with other childhood vaccines. 3 tables. 18 references. (AA-M). •

Hepatitis B Carriage Explains the Excess Rate of Hepatocellular Carcinoma for Maori, Pacific Island and Asian People Compared to Europeans in New Zealand Source: International Journal of Epidemiology. 28(2): 204-210.

Summary: This article reports on a study undertaken to determine the prevalence of hepatitis B surface antigen (HBsAg) carriers among cases of hepatocellular carcinoma (HCC), and the population attributable risk of HBsAg carriage for HCC, by ethnicity in New Zealand. The authors reviewed the hospital notes of HCC cases registered with the New Zealand Cancer Registry for the years 1987 to 1994. The HBsAg status was determined for 193 cases of HCC. The HBsAg carrier prevalence for non Europeans with HCC was markedly higher than that for Europeans (76.7 percent for Maori, 80.0 percent for Pacific Island people, and 88.5 percent for Asians, compared to 6.0 percent for Europeans). In addition to the effect of ethnicity, HCC cases younger than 60 years were more likely to be HBsAg carriers than those older than 60. The estimated population attributable risk of HBsAg for HCC, within each ethnic group, was only marginally less than the HBsAg prevalence due to the high relative risk of HBsAg carriage for HCC. The standardized incidence rate ratios of HCC for Maori, Pacific Island people, and Asians compared to Europeans were 9.6, 20.4, and 22.3, respectively. HCC attributable to HBsAg carriage explained 79 percent, 83 percent, and 92 percent of the excess standardized rate for Maori, Pacific Islanders, and Asians, respectively. The authors conclude that their data predict that 75 to 90 percent of the cases of HCC that will occur in the target population (subpopulations of New Zealand) will occur among HBsAg carriers and are therefore potentially detectable by ongoing screening. 5 tables. 28 references.

Summary: This article reviews a study conducted to determine the prevalence in arrestees of syphilis, hepatitis B virus (HBV), and HIV infection by demographic and behavioral characteristics, and to evaluate the costs associated with universal screening for these sexually transmitted diseases compared with a theoretical targeted screening program. Three hundred and nineteen arrestees were screened for syphilis, HBV, and anonymously for HIV infection. The prevalence of syphilis was 2.5 percent; hepatitis B surface antigen prevalence was 1.6 percent; the prevalence of past or present HBV infection was 21.9 percent; and the prevalence of HIV infection was 1.6 percent. Targeted screening for sexually transmitted diseases was found to be more costeffective.

PRICE: $47. ISBN: 0824305450. Summary: This article reviews current treatment strategies for chronic hepatitis B and hepatitis C, two types of liver inflammation caused by the hepatitis virus. For chronic hepatitis B, treatment with a 4 month course of interferon alfa-2b can achieve hepatitis B e antigen seroconversion, normalization of aminotransferase levels, reduced hepatic inflammation, and possibly reduced progression to cirrhosis (liver scarring), and improvement in survival in 20 to 30 percent of patients. Similar results can be achieved with a 12 month course of lamivudine, with response rates increasing to 40 to 65 percent after 3 years of therapy. Interferon can also be used in early cirrhotic patients, and lamivudine can be used in people with advanced cirrhosis and in immunosuppressed

Hepatitis B

patients. Combination interferon and lamivudine therapy does not confer additional benefits. For chronic hepatitis C, the combination of interferon alfa-2b and ribavirin in the treatment of choice, offering superior sustained response rates (40 percent) compared with interferon alone (15 percent). Therapy should be administered for 12 months to patients with genotype 1 virus but for only 6 months to patients with genotypes 2 and 3. Patients experiencing relapse after 6 months of interferon monotherapy can be re-treated with interferon and ribavirin or high-dose interferon, with 45 to 56 percent sustained response rates. However, relatively few patients who are prior nonresponders to interferon monotherapy will have sustained response to further interferon-based treatments, including combination therapy with ribavirin. Successful therapy not only leads to the eradication of viral RNA but also may delay progression to cirrhosis and hepatocellular carcinoma (HCC, liver cancer). Interferon combined with polyethylene glycol (PEG) shows promise as an improved formulation of interferon with yet higher sustained response rates. 1 figure. 6 tables. 99 references. •

(205) 945-1840. Summary: This article reviews the current methods of diagnosis and treatment of hepatitis B virus (HBV) infection. Physicians are now able to accurately diagnose acute and chronic hepatitis infection, though the understanding of viral quantitation and its impact on disease course and treatment response is evolving. The author notes that hepatitis B must now be considered a preventable disease, since acute infection can be effectively prevented by either passive or active immunization. However, when acute infection does occur, it evolves into chronic hepatitis or a chronic infectious carrier state in a variable proportion of cases, depending on the age and underlying immune competence of the patient. Chronic infection can be treated, though the effectiveness of available antiviral and immunomodulatory agents is less than complete. Finally, the author notes that variants of the HBV are being recognized and coinfection with the defective viroid known as hepatitis D has been described. 5 figures. 15 references. (AAM).

Summary: This article reviews the current status of hepatitis B immunization programs as well as future issues concerning hepatitis B immunization in Asian countries. The literature was identified via in house and MEDLINE (1980 to 1999) searches and references cited in published articles. Results showed that chronic hepatitis B infection is responsible for 75 to 90 percent of primary hepatocellular carcinoma (liver cancer), one of the 10 most common cancers worldwide. Hepatitis B and its chronic sequelae can potentially be eradicated through vaccines that have been shown to be 95 to 99 percent effective in preventing development of the disease or the carrier state in immunized infants. Approximately 75 percent of the world's hepatitis B carriers live in Asian countries wherein wide variations in immunization strategies exist. Vaccination

programs in hyperendemic Asian countries have elicited decreases in the incidence of acute and chronic infections as well as a decrease in chronic carriers in the unvaccinated population. Decreases in the incidence of hepatocellular carcinoma have been recorded in Taiwan and Singapore after at least 10 years of universal hepatitis B immunization programs. The authors conclude that, in Asian countries currently without nationwide hepatitis B programs, utilization of the existing vaccination infrastructure (for administration of other World Health Organization vaccines) will provide the most economical and efficient means of administration of the hepatitis B vaccine. 3 tables. 40 references. •

(800) 432-4570. Summary: This article reviews the current thinking regarding the transmission, pathogenesis, diagnosis, prevention, and treatment of hepatitis B virus (HBV). In geographic areas such as the United States, with a low prevalence of HBV infection, sexual contact is the most common mode of transmission of the virus. The illegal use of injection drugs, particularly among those who share unsterilized needles, accounts for 23 percent of cases of HBV transmission in the United States. Health care workers are a recognized HBV risk group because of their exposure to needles, syringes, and other objects contaminated with blood, bodily fluids, or other secretions from infected individuals. The host immune response appears to be more important than viral factors in the pathogenesis of HBV infection. The serologic hallmark of chronic HBV infection is the presence of hepatitis B surface antigen (HBsAg) for a period of more than 6 months. Immunocompromised adults and those who are infected with HBV in early childhood are at 50 percent risk of developing chronic infection. Measures that reduce the risk of exposure to HBV include sexual behavior changes and need exchange programs for injection drug users. Vaccination is now recommended for high risk groups and for all children. The authors discuss treatment options, including postexposure prophylaxis, lamivudine therapy, and other strategies, notably immunomodulator and antiviral drugs. One sidebar briefly reviews the epidemiology of HBV worldwide. 1 figure. 4 tables. 13 references.

Characteristics of and Current Treatment Options for Hepatitis B and Hepatitis C Source: Journal of the Canadian Dental Association. 66(10): 537. November 2000. Contact: Available from Canadian Dental Association. 1815 Alta Vista Drive, Ottowa, ON K1G 3Y6. (613) 523-1770. E-mail: [email protected]. Website: www.cda-adc.ca. Summary: This brief article reviews the characteristics of and current treatment options for hepatitis B and hepatitis C, focusing on the risks to health care workers, including dental professionals. The author provides information about the natural history, therapeutic choices, and future directions of therapy for these two forms of hepatitis. Not all patients who test positive for hepatitis B surface antigen (HbsAg) require antiviral therapy; many people have circulating HBsAg without evidence of significant hepatitis. These people are chronic carriers and account for the majority of hepatitis B cases. Treatment options include alpha interferon or oral lamivudine; however, conversion to negative status is achieved in only approximately 20 percent of cases with either therapy. Hepatitis C is a common condition affecting approximately 2 percent of Canadians; of patients with chronic hepatitis C, approximately 20 percent experience serious liver complications. These complications can include cirrhosis, need for liver transplantation, hepatocellular carcinoma (liver cancer), or death. Standard treatment for hepatitis C is alpha interferon and ribavirin; sustained remission occurs in approximately 40 percent of cases. The article concludes with the website for the Canadian Association for the Study of the Liver (www.lhsc.on.ca/casl/summ.htm ).

Hepatitis B e Antigen: The Dangerous Endgame of Hepatitis B. (editorial) Source: New England Journal of Medicine. NEJM. 347(3): 208-210. July 18, 2002. Summary: This editorial familiarizes readers with the complication of hepatitis B that results in the hepatitis B e antigen (HBeAg). Shortly after the discovery of hepatitis B virus (HBV), the striking epidemiological association between HBV infection and liver cancer (hepatocellular carcinoma) was noted. Subsequent research demonstrated that the risk of liver cancer was increased by a factor of 10 among men who were positive for HBsAg (hepatitis B surface antigen) alone and by a factor of 60 among those who were positive for both HBsAg and HBeAg. Older age, the presence of antibodies against hepatitis C virus, cigarette smoking, and use of alcohol were also identified as independent risk factors for the development of liver cancer. The author explores the evidence for the role of HBeAg and notes that although this proposed role of HBeAg may contribute to the development of liver cancer, it is most likely that its role as a marker of active virus replication is associated with the increased risk in cancer. The author also briefly considers the pathogenesis of HBV-associated liver cancer, the role of environmental hepatotoxins (liver toxins), and the strategies used to fight HBV (vaccination and drug therapy). 1 figure. 16 references.

Public's Health Unprotected: Reversing a Decade of Underutilization of Hepatitis B Vaccine (editorial) Source: JAMA. Journal of the American Medical Association. 274(15): 1242-1243. October 18, 1995. Summary: This editorial highlights and praises the progress that has been made in hepatitis B vaccination in the United States, while examining why it takes so long to apply safe, effective, and low-cost preventive modalities to improve public health. The author first reviews a success story in which, in an extremely high incidence area, HBV transmission has all but been eliminated. The author then discusses the findings of two other articles from this issue of the journal that also document advances in this area. The remainder of the editorial focuses on the length of time required to institute an aggressive vaccination program and how leaders in the biomedical, public health, and political arenas must become more cognizant of the need for vaccination programs. The author concludes with a challenge to physicians to help eliminate hepatitis B. 15 references.

Is Hepatitis A More Severe in Patients with Chronic Hepatitis B and Other Chronic Liver Diseases? Source: American Journal of Gastroenterology. 90(2): 201-205. February 1995. Summary: This review article analyzes published literature on the clinical course and outcome of acute hepatitis A in patients with chronic hepatitis B virus (HBV) infection and other chronic liver diseases, to determine if hepatitis A is more severe in these patients. The author reviews epidemics and large case series; small case series and case reports; and hepatitis A in other chronic liver diseases. The author concludes that the

data seem to suggest that acute hepatitis A superimposed on chronic HBV infection is associated with higher peak laboratory abnormalities, more severe disease, including fulminant hepatic failure, and a higher case fatality rate. These conclusions, however, are not supported by all case series or case reports. 1 table. 17 references. (AA-M). •

Website: www.blackwell-science.com. Summary: This review article discusses hepatitis B virus (HBV) infection, a major global health concern and the most common cause of chronic liver disease worldwide. The natural history and clinical outcomes of chronic HBV infection are determined by the viral replication cycle and the host immune responses. Treatment of chronic hepatitis B is directed at interrupting the natural history of suppressing HBV replication before development of any significant irreversible liver cell damage. Two major classes of antiviral therapeutic agents that have been approved for treatment of chronic hepatitis B are immunomodulating agents (i.e., interferon) and the nucleoside analogs (i.e., lamivudine). A major problem of antiviral treatment is the emergence of drug resistance. Many new immunomodulatory therapies and antiviral agents are in various stages of clinical development and have shown some promise. Among newer HBV antivirals, adefovir dipivoxil, entecavir, emtricitabine, DAPD, and clevudine appear to be at least as potent as lamivudine in suppressing HBV replication. The author hypothesizes that combinations of an immunomodulatory agent and nucleoside analog may improve the therapeutic efficacy and reduce the emergence of drug resistance. Nevertheless, combinations of interferon and lamivudine therapies do not confer such additional benefits. The next challenge for HBV treatment is to use antivirals in combination or cyclical therapy to minimize the emergence of drug resistance and increase efficacy, particularly to achieve sustainable post treatment suppression of HBV. 4 tables. 147 references.

Website: www.blackwell-science.com. Summary: This review article focuses on hepatitis B virus (HBV) infection, a global health problem. The clinical outcome of chronic HBV infection depends on the frequency and severity of hepatitis flares in the immune clearance phase. Currently, four subtypes and seven genotypes of HBV are identified and most have specific geographic distributions. The impact of HBV genotypes on the clinical outcome of chronic HBV infection has been partially clarified. The author provides numerous examples from Taiwan, Japan and China. The author concludes that pathogenic (how the disease develops) and therapeutic differences do exist among HBV genotypes, and determining the genotype in patients with chronic HBV infection would help gain further information for etiologic (causative), clinical, virologic, and anthropologic investigations. 1 figure. 2 tables. 61 references.

Treatment of Chronic Hepatitis B Virus Infection in Special Groups of Patients: Decompensated Cirrhosis, Immunosuppressed and Paediatric Patients Source: Journal of Gastroenterology and Hepatology. 15(Supplement): E71-E78. May 2000. Contact: Available from Blackwell Science. 54 University Street, Carlton South 3053, Victoria, Australia. +61393470300. Fax +61393475001. E-mail: [email protected]. Website: www.blackwell-science.com. Summary: Treatment of special groups of patients (i.e., patients with decompensated cirrhosis, immunocompromised patients, and children) is challenging and requires different treatment strategies. This article explores the management of chronic hepatitis B in these special populations. Patients with decompensated liver disease have a poor prognosis and are difficult to treat. Chances of survival for this group are limited without liver transplantation. Interferon alpha (IFN alpha) is presently the recommended treatment for patients with clinically stable chronic hepatitis B. The aim of treatment is to permanently suppress or eliminate HBV infection and thereby induce remission of liver disease. The author notes that there is increasing interest in the use of nucleoside analogues in the treatment of decompensated liver disease and those going

for liver transplantation. The author discusses the use of thymosin alpha 1 and lamivudine as treatment options. Chronic hepatitis B is common in immunosuppressed patients, including antiHIV positive patients, patients with chronic renal failure, and patients undergoing organ transplantation. Unfortunately, their response to IFN therapy is poor, mostly because of high level viraemia (levels of virus in the blood) and depressed cell mediated immunity. The prevalence of hepatitis B in Asian children is probably similar to that in adults. Infection acquired early in life may not progress to liver disease until later in childhood or early adulthood. However, both cirrhosis and liver cancer (hepatocellular carcinoma, or HCC) have been documented in children. It is therefore important to consider effective therapy for children with chronic HBV infection and to monitor these children closely for HCC. 64 references.

Federally Funded Research on Hepatitis B The U.S. Government supports a variety of research studies relating to hepatitis B. These studies are tracked by the Office of Extramural Research at the National Institutes of Health.2 CRISP (Computerized Retrieval of Information on Scientific Projects) is a searchable database of federally funded biomedical research projects conducted at universities, hospitals, and other institutions. Search the CRISP Web site at http://crisp.cit.nih.gov/crisp/crisp_query.generate_screen. You will have the option to perform targeted searches by various criteria, including geography, date, and topics related to hepatitis B. For most of the studies, the agencies reporting into CRISP provide summaries or abstracts. As opposed to clinical trial research using patients, many federally funded studies use animals or simulated models to explore hepatitis B. The following is typical of the type of information found when searching the CRISP database for hepatitis B: •

Project Title: A RANDOMIZED TRIAL OF VACCINE ADHERENCE IN YOUNG IDU Principal Investigator & Institution: Lum, Paula J.; Medicine; University of California San Francisco 500 Parnassus Ave San Francisco, Ca 94122 Timing: Fiscal Year 2003; Project Start 30-SEP-2003; Project End 30-JUN-2007 Summary: (provided by applicant): We propose a study to examine strategies to deliver a promising preventive HIV vaccine candidate-employing a surrogate hepatitis B vaccine-to a cohort of high-risk young injection drug users (IDU) and young male IDU that have sex with men (MSM-IDU). We will screen 750 IDU aged 29 or less in San Francisco and over sample MSM-IDU, who have very high rates of HIV seroconversion. We expect that about 50% of those screened will meet eligibility criteria for prospective study and of those, that 80% will enroll. We will follow this cohort of 300 individuals for one year, administering a combined hepatitis A virus (HAV) inactivated and hepatitis B virus (HBV) recombinant vaccine (Twinrix() to study medical management and implementation issues, including: (1) adherence to multi-dose immunization schedules, (2) novel methods to minimize losses to follow-up, and (3) physiologic and behavioral

factors that may alter vaccine effectiveness. The primary purpose of the study is to efficiently compare interventions to improve vaccine series adherence. In particular, we propose a randomized trial using a factorial design to compare the effects of clinical setting (syringe exchange program vs. immunization clinic) and outreach worker support (outreach vs. none) in enhancing adherence to a multiple dose immunization schedule. We have three secondary objectives. The first focuses on transience, one of the major causes of attrition in cohort studies of often-homeless IDU and other disenfranchised populations. For subjects who leave San Francisco during the study period, we will use novel technology to map their travel and achieve immunizations remotely. Secondly, we will compare vaccine effectiveness between HCV-infected and uninfected young IDU. We will measure protective antibody levels after immunizations. Finally, given the potential for reduced vaccine effectiveness in the setting of continued high-risk behavior, we will measure changes in behavior and vaccine attitudes. By testing strategies for delivering a multi-dose schedule of hepatitis vaccine and developing models for improving future HIV vaccine adherence and effectiveness, we can advance HIV vaccine development for young adult high-risk injection drug users.

Project Title: ADJUVANTED DNA VACCINE FOR IMMUNOTHERAPY HIV INFECTION Principal Investigator & Institution: Haynes, Joel R.; Powderject Vaccines, Inc. 585 Science Dr Madison, Wi 53711 Timing: Fiscal Year 2001; Project Start 30-SEP-2001; Project End 31-MAR-2004 Summary: The goal of this program is the optimization and evaluation of an adjuvanted therapeutic DNA vaccine strategy for AIDS using the rhesus monkey/SIV model system. In addition, a graduated clinical evaluation approach is planned to introduce this technology into the clinic in a stepwise manner. The DNA vaccine to be employed will encode the full length gag, pol, and env products of SIV as well as a series of defined CTL epitopes fused to an immunogenic carrier protein. The novelty of our approach centers on the inclusion of an adjuvant vector encoding the A and B subunits of cholera toxin (CT) or the E. coli heat labile enterotoxin (LT) to augment antigenspecific Th1 immunity and systemic and mucosal CTL responses. The adjuvanted DNA vaccine will be formulated onto microscopic gold particles and delivered to the skin as a therapeutic vaccine using a clinical "gene gun" device. Elucidation of the mechanism of adjuvant action will be assisted by the analysis of chemokine involvement and the activation and trafficking of dendritic cells. Justification of the proposed approach is based on three important findings from our laboratories: 1, Human clinical evaluation of a "gene gun"-based DNA vaccine for hepatitis B resulted in the induction of vigorous antigen-specific, Th1 and cytotoxic cellular immune responses in humans, confirming the clinical effectiveness of this means of DNA vaccine delivery. 2, The induction of SIVspecific CTL responses via gene gun-based DNA vaccination in the rhesus/SIV model provides measurable protection from challenge with pathogenic SIVdeltaB670. 3, The formulation of DNA vaccines with vectors encoding eith4r CT or LT results in marked and surprising enhancements of Th1 and CTL responses without any evidence of local or systemic toxicity in small and large animals. Clinical development of the adjuvanted DNA vaccine approach will take place in a graduated manner involving initial evaluation of a single HIV therapeutic DNA vaccine vector in a small phase I/II trial. A second clinical trial attempting to establish clinical proof of concept of the adjuvanted DNA vaccine approach will follow. The later trial will include the addition of a vector encoding CT or LT.

Project Title: ADULT AIDS CLINICAL TRIALS UNIT Principal Investigator & Institution: Goldman, Mitchell; Medicine; Indiana Univ-Purdue Univ at Indianapolis 620 Union Drive, Room 618 Indianapolis, in 462025167 Timing: Fiscal Year 2002; Project Start 01-JAN-2000; Project End 31-DEC-2004 Summary: (adapted from application's abstract): The Indiana University proposes to build upon the following in the renewal application: (1) scientific and administrative contributions. The Indiana ACTU ranks among the top 20 percent of ACTUs scientifically; (2) cost efficient accrual into AACTG trials. Indiana ranked third in cost weighed accrual; and (3) recruitment of women and minorities. The ACTU ranked second in recruitment of African- Americans and third in women. The long-term objectives of this site are to: expand scientific and administrative contributions through recruitment of additional investigators; increase accrual potential for women and minorities by expansion of the Wishard Hospital subunit; and increase the patient base by establishing a subunit at Community Hospital of Indianapolis. The first specific aim of the Indiana University ACTU is to contribute scientifically through submission of concept proposals and memberships on AACTG protocol teams and committees. Currently, Indiana investigators hold 32 positions on protocol teams. Concepts are proposed for: (a) salvage therapy for efavirenz failures; (b) evolution of anal dysplasia and the role of HPV in patients on HAART; (c) the role of gp 120 in HIV induced apoptosis of neurological cells in pathogenesis of dementia; (d) the role of GM-CSF and CD4 ligand on immunity to H. Capsulatum and HIV-1; (e) use of in vitro assays for drug interactions with protease inhibitors; and (f) the role of intestinal metabolism and bioavailability of antiretroviral drugs. The second specific aim is to expand the patient base, including women and minorities, though increased support for subunits at Wishard Hospital and Community Hospital. The work proposed in this application will be implemented through conduct of clinical trials as a member the AACTG, using an infrastructure that has been refined during 12 years as an ACTU.

Project Title: AFB1 AND P53 CARCINOGENESIS IN HBSAG TRANSGENIC MICE Principal Investigator & Institution: Sell, Stewart; Professor; Pathology and Lab Medicine; Albany Medical College of Union Univ Union University Albany, Ny 12208 Timing: Fiscal Year 2001; Project Start 15-DEC-1998; Project End 30-NOV-2002 Summary: The interaction and mechanisms of the major risk factors for human hepatocellular carcinoma (HCC) will be analyzed in an animal model. World- wide HCC is arguable the tumor that causes the highest cancer mortality. HCCs occurring in high-risk areas of the world are associated with hepatitis B(HBV) infection and aflatoxin (AFB1) exposure, and these tumors have a high frequency of mutations in the tumor suppressor gene p53 at codon 249 (p53ser249). In specific Aim 1, the effect of expression of p53, HBV injury and AFB1 exposure on development of pre-neoplastic lesions and HCC development will be studied using F1s of p53 null mice X HBsAg transgenic lineage 50-4 mice. In specific aim 2, the effect of p53 mutation will be determined using a newly established mutant p53ser246 (equivalent to human p53ser249) mouse lineage. In specific aim 3 the mechanisms for effects of loss on p53, p53 mutation and AFB1 exposure on hepatocyte proliferation during carcinogenesis will be examined by analysis of specific cell cycle events and expression or reactivity to liver growth factors.

Project Title: ANTIGEN SPECIFIC MODULATION OF T CELL RESPONSES Principal Investigator & Institution: Schneck, Jonathan P.; Associate Professor; Pathology; Johns Hopkins University 3400 N Charles St Baltimore, Md 21218 Timing: Fiscal Year 2001; Project Start 01-JUN-1999; Project End 31-MAY-2004 Summary: Using Ig as a molecular scaffold, we have developed a general approach to making soluble divalent analogs of MHC class I and II molecules (MHC-I/Ig and MHCII/Ig). The divalent nature of these molecules effectively increased the affinity of these analogs for their cognate ligands, antigen specific T cells. Peptide loaded divalent high affinity MHC analogs (pepMHC/Ig) can be used to directly visualize antigen specific T cells by flow cytometry. The goals of the current application are to selectively modulate and monitor antigen-specific T cell responses in murine models using pepMHC/Ig complexes. Our first specific aim will focus on defining the mechanism of in vitro CTL modulation by pepMHC-I/Ig complexes. We will determine if pepMHC/Ig complexes inhibit 2C CTL by competitive inhibition, induction of anergy, or induction of apoptosis. The second specific aim will analyze the effects of pepMHC-I/Ig complexes on T cells in vivo using two model systems: peptide- specific 2C CTL and a Hepatitis B specific CTL, 6C2. The influence of pepMHC-I/Ig on both trafficking and modulation of CTL responses in vivo will be defined. Initial experiments will be aimed at optimizing platform development for homogeneously loading MHC-I/Ig complexes with the peptides of interest. Trafficking studies on 2C CTL will be studied using B6 animals injected with P815 tumor cells and suppression will be studied in a 2C-mediated model of diabetes. We will analyze the effects of HepBLd/Ig on Hepatitis B specific CTL by characterizing the ability of HepBLd/Ig complexes to: bind to HepB specific CTL, inhibit HepB specific CTL mediated lysis of target cells in vitro, and modulate hepatocellular necrosis in HBsAg transgenic mice injected with 6C2, HepB specific CTL in vivo. Should the direct modulation of specific CTL in vivo prove ineffective, the ability of pepMHC-I/Ig coupled to a fungal toxin, ricin, to specifically kill T cells in vitro and in vivo will be analyzed. To analyze the ability of pepMHC/Ig complexes to selectively regulate class II-restricted immune responses, we will study the ability of pepMHC-II/Ig compounds to modulate class II-restricted, immune responses. The model system to be analyzed will be the effects of MCCI-Ek/Ig on cytochrome-specific immune responses. Analysis of the effects of soluble divalent class II MHC molecules will reveal several interesting and unique features about regulation of class II-restricted immune responses. The first part of this specific aim we will analayze modulation of in vitro immune responses by MHC-II/Ig complexes and also address the ability of soluble divalent analogs of peptide antagonists complexed to the I-Ek/Ig molecule to modulate in vitro immune responses. In the second part of this specific aim we will study the ability of MHC-II/Ig complexes to modulate in vivo immune responses. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen

Hepatitis B

Timing: Fiscal Year 2001; Project Start 30-SEP-2001; Project End 31-AUG-2003 Summary: (provided by applicant): The global magnitude of hepatitis B viral (HBV) infection warrants development of efficient treatment strategies to combat the virus. These treatment protocols will also aid in minimizing the protracted long-term effects of HBV infection namely cirrhosis and hepatocellular carcinoma. The short-term benefits of the currently available treatment protocols are greatly offset by the emergence of the resistant phenotype in the case of Lamivudine therapy and adverse side effects in the case of alpha-interferon. As a consequence of this, the goal of maintaining low viral loads cannot be achieved. The generation of a panel of potent antivirals against HBV would be a valuable addition to existing treatments. Novel combinations of anti-HBV drugs would greatly minimize the chances of development of resistance and provide sustained reduction in viral loads. A number of 2'-fluoro-2',3'-unsaturated D- and Lnucleosides (2'-F-D4N) showed potent anti-HBV activity with no appreciable toxicity in a number of cell lines. These compounds also demonstrated anti-HIV activity in vitro. In the proposed Phase I study, these compounds will be further characterized with respect to their anti-HBV activity in combination treatments, mechanisms of action, mitochondrial toxicity, and efficacy of inhibition of HBV viral polymerase. Crossresistance of these active nucleosides against the Lamivudine-resistant mutants will be determined. Pharmacokinetics of molecules with antiviral activity and no appreciable cellular and mitochondrial toxicity will be conducted. At the conclusion of the Phase I study, it should be possible to identify one or two best candidate molecules for detailed studies in animal models, preclinical studies and further development. Detailed studies for phase II studies which will include in vivo efficacy and sub chronic toxicology of the compounds. PROPOSED COMMERCIAL APPLICATION: There is an urgent need for therapies for the treatment and management of HBV worldwide. Limited success of the Lamivudine monotherapy and development of clinical resistance to Lamivudine have made the researchers as well as clinicians aware of the fact that alternate modalities of treatment have to be in place to tackle HBV infections successfully. Novel anti-HBV agents, hence, would have a much broader market as new combinations of drugs can be formulated. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen •

Project Title: CLIN. & HISTOLOGIC SPECTRUM OF HCV LIVER DISEASE IN IDU Principal Investigator & Institution: Edlin, Brian R.; Associate Professor of Medicine and Publ; Family and Community Medicine; University of California San Francisco 500 Parnassus Ave San Francisco, Ca 94122 Timing: Fiscal Year 2001; Project Start 30-SEP-1999; Project End 31-AUG-2002 Summary: Injection drug users (IDUs) have the highest hepatitis C (HCV) infection rates of any risk group in the United States; fully 70-96 percent of IDUs have been infected. Natural history studies of transfusion recipients have suggested that HCV infection represents a slowly progressive disease culminating in cirrhosis and liver cancer after decades. But while active IDUs represent the largest single group of persons infected with HCV, there are no studies to date describing the prevalence and severity of HCVrelated liver disease among street-recruited, actively injecting IDUs. Because most IDUs acquired HCV when they began injecting decades ago, many are at imminent risk for life-threatening complications. We propose a cross-sectional study of 1000 active, streetrecruited IDUs who test positive for HCV antibody in the Urban Health Study's ongoing program of HIV and hepatitis testing in inner-city neighborhoods in San Francisco. Indepth epidemiological, clinical and laboratory evaluations of HCV-positive participants will be conducted to assess signs, symptoms, and correlates of liver disease. A subset of

200 HCV-positive participants will undergo liver biopsies. Specifically, this study aims to: 1) to describe the clinical and laboratory spectrum of HCV-related liver disease among 1000 active, street-recruited IDUs in San Francisco, 2) to determine the correlates of advanced liver disease among active IDUs, including demographic factors, injection and other behaviors, comorbidities, and viral markers. Advanced liver disease will be defined as Child-Pugh score B or greater, 3) to describe the histologic spectrum of HCVrelated liver disease in a subset of 200 active IDUs who will undergo liver biopsy, and 4) to determine the correlates of progressive liver disease among the 200 IDUs who undergo biopsy. Progressive liver disease will be defined as fibrosis stage 3 or 4 on liver biopsy. In addition, contact information will be collected so that this cross-sectional study can serve as a baseline for future cohorts to examine the incidence of clinical and histological disease in this cohort.

Project Title: CLINICAL AND CELLULAR EFFECTS OF INTERFERON ALFA 1 Principal Investigator & Institution: Borden, Ernest C.; Director; Cleveland Clinic Foundation 9500 Euclid Ave Cleveland, Oh 44195 Timing: Fiscal Year 2001; Project Start 01-JUL-2001; Project End 30-JUN-2006 Summary: Using a preparation that was in limited supply, we previously assessed Interferon-alpha 1 (IFN-alpha 1) clinically in a randomized, double blind comparison to IFN-alpha 2. The frequency of side effects was much less with IFN-alpha1 (p less than 0,01). Yet effects of IFN-alpha 1 on granulocyte counts, NK cell cytotoxicity, and an ISG were comparable to IFN-alpha2. These findings suggest that IFN-alpha 1 might be given with better tolerance and or higher doses than IFN-alpha 2. Recombinant DNA produced IFN-alpha 1 has now come available in adequate supply through a collaboration with the Ministry of Public Health in Shanghai. In randomized, multicenter clinical trials in China, IFN-alpha 1 has proven effective for chronic hepatitis B and C. Data from China also suggests IFN-alpha 1 is better tolerated than IFN-alpha 2. IFN-alpha 1, together with IFN-alpha 2, is a predominant IFN-alpha species generally characteristic of an IFN. However, IFN-alpha 1 has differing receptor binding affinities and differing cross species antiviral activity differences in the transcription factor complexes activated in response to IFN-alpha 1 as compared to IFN-alpha 2. In addition to expected IFN antiproliferative and gene stimulatory (ISG) effects, we have also identified an increase in STAT1 protein expression and induction of apoptosis in myeloma cells by IFN-alpha 1. Studies of IFN-alpha have been designed with the following goals: a) confirm good clinical tolerance and define the dose response characteristics of ISG induction in patients, b) compare the signal transducing and gene modulatory activity to those of IFN-alpha 2 by oligonucleotide gene array and assessment of transcription activating factors, c) study apoptosis and gene induction in myeloma and renal carcinoma to confirm clinical antitumor activity. Since expanded clinical use of IFN- alpha 2 has increasingly been limited by side effects, IFN-alpha 1 may be particularly important in extending clinical leads provided by LFN-alpha 2. Finally, results will further confirm the postulate that antiviral specific activity in vitro does not predict for other biological and clinical effects of IFN. In addition, if the pattern of novel gene induction and cellular effects are expanded, IFN-alpha 1 could have a broader spectrum of responsive clinical tumor types.

Project Title: CLINICAL TRIAL OF SHORT COURSE VS. INH FOR LTBI IN JAIL Principal Investigator & Institution: White, Mary C.; Community Health Systems; University of California San Francisco 500 Parnassus Ave San Francisco, Ca 94122 Timing: Fiscal Year 2003; Project Start 30-SEP-2003; Project End 31-MAR-2007 Summary: (provided by applicant): Tuberculosis (TB) in incarcerated populations is a serious problem, due to the large proportion of inmates who are at high risk of having latent tuberculosis infection (LTBI) and developing active disease. Completion of treatment of LTBI has not been successful in jails, mainly because inmates are frequently released before finishing a 6-9 month course of standard therapy with daily isoniazid (INH), and because they have low rates of completing therapy in the community. Effective treatment of LTBI is complicated by length of therapy and toxicity of the drugs used against L TBI. Short-course therapies for LTBI may address this problem but they have not been studied adequately to answer questions about side effects, completion rates, and overall cost. We propose a two arm, open label randomized trial to test the effects of a short-course therapy for LTBI in jailed inmates; rifampin given daily for 4 months as compared to INH given twice weekly for 9 months. A sample of 972 consented and enrolled participants will be administered directly observed therapy (DOT) in jail. The study protocol includes links to the TB Clinic for post-release DOT, and close clinical and laboratory monitoring throughout the course of therapy. Participants will be followed, in jail and after release, for one year after enrollment, to measure three outcomes: toxicity, adherence, and cost-effectiveness. Toxicity leading to stopping drug will be analyzed by study group, and other predictors will be examined, such as age, alcohol use and hepatitis B and C. Adherence, measured by completion of therapy, will be compared by study group, and other predictors will be examined, including sociodemographic variables, intent to adhere, and stability of housing. Costeffectiveness will be compared by study group and will be calculated using direct costs of administering and monitoring care and costs of re-starting care in this population with a high rate of re-arrest, measured against the cost of prevented cases of TB. Short course regimens are promising in the inmate population to treat LTBI and eliminate risk of progression to active disease. This study will answer questions about the safety of rifampin compared directly to INH. Analysis of completion of therapy and costeffectiveness of this regimen will provide important information for policy change in the way L TBI is managed in jail.

with immediate applications to cost- effective screening in internationally adopted (IA) children. Two complementary studies are proposed that address the clinical and costeffectiveness of hepatitis B virus (HBV) and tuberculosis (TB) screening in IA children. These studies are based on the hypothesis that focused, rational screening can provide a cost-effective means for improving the long-term health outcomes of immigrant children and is consonant with public health imperatives. Each study involves primary collection of new data that address important gaps regarding the prevalence and risk factors for infectious diseases in IA children, and the utility of markers (skin tests and immunization history) to predict infection, disease or protective immunity. This will provide new information regarding the infectious disease burden, and its expression, in the growing group of IA children in the US. These new data also will provide estimates necessary for cost-effectiveness analyses that will be developed to assess the utility of alternative approaches for immunization and TB screening. The proposal addresses important knowledge gaps about the health of children immigrating to the US from resource-poor environments and may provide important new data for rational and costeffective screening in IA children. The cohort of children developed in this proposal may be followed in future research designed to answer challenging questions with respect to the long-term impact of early screening and preventive TB therapy. Finally, the proposal will provide a key training opportunity to foster the candidate s career development as an epidemiologist with a commitment to patient oriented research.

Project Title: COUPLES HIV INTERVENTION RANDOMIZED CONTROLLED TRIAL Principal Investigator & Institution: Mcmahon, James M.; National Development & Res Institutes Research Institutes, Inc. New York, Ny 10010 Timing: Fiscal Year 2003; Project Start 26-SEP-2003; Project End 30-JUN-2007 Summary: The broad, long-term objective of the proposed research is to establish primary preventive interventions to reduce human immunodeficiency virus (HIV) risk behavior among drug-using minority women. Recent studies indicate that high rates of sexual risk behavior occur within drug-using minority women's primary heterosexual relationships. Based on an integrated theory of HIV risk behavior, it is predicted that a) interventions administered to couples rather than to women only, and b) interventions that focus on relationship dynamics in the context of HIV risk, will result in a reduction of sexual risk behavior among drug-using women and their primary partners. This fouryear study will employ a randomized controlled trial (RCT) 3-group design to test the efficacy of HIV intervention modality (couples versus women-only) and intervention content (relationship-focused versus standard HIV counseling and testing) on crack, cocaine and heroine (injected and noninjected) using women's sexual risk with primary partners. A total of 390 women drug-users and their partners will be recruited from the streets of East Harlem, New York City. Participants will be randomly assigned to one of three HIV intervention conditions: a) couples, relationship-focused; b) women-only, relationship-focused; or, c) women-only standard HIV-CT (control). All subjects will be administered baseline, 3-month, and 9-month follow-up assessments using a combination of computerassisted personal interview (CAPI) and computer-assisted self interview (CASI) techniques. In addition to sociodemographic characteristics, the interview will measure drug-use patterns, HIV risk behavior, and dyadic- and individual-level variables operationalized to test specific hypotheses of women's HIV risk behavior and behavior change. In addition to testing the effectiveness of the experimental interventions, data analyses will determine the theory-driven psychosocial

mechanisms that act to mediate and moderate any observed association between intervention treatment and subsequent risk reduction. Incremental cost-effectiveness analyses will also be performed. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen •

Project Title: DIETARY FACTORS IN THE ETIOLOGY OF CANCER IN SHANGHAI Principal Investigator & Institution: Ross, Ronald K.; Professor; Preventive Medicine; University of Southern California 2250 Alcazar Street, Csc-219 Los Angeles, Ca 90033 Timing: Fiscal Year 2001; Project Start 01-APR-1987; Project End 30-JUN-2002 Summary: (Adapted from the Applicant's Abstract): We are requesting continued support for an ongoing cohort study of 18,244 men, ages 45-64, living in a geographically defined area of metropolitan Shanghai, Peoples Republic of China. All cohort members have completed detailed diet and medical histories and have blood and urine samples. Questionnaires have been edited and computerized and blood and urine samples have been processed, aliquoted, and continuously stored at both -20_C and 70_C. The cohort was fully established in 1989. Follow-up of the cohort is proceeding through cancer registration by the population-based Shanghai Cancer Registry, by routine ascertainment of death certificates, and by annual recontact of all cohort members. As of March 1994, 606 have developed cancer and 989 have died. The leading cancers include lung, stomach, liver, and colorectal cancers, while stroke is the number one cause of death. Major accomplishments achieved through this cohort to date include: (1) the first direct evidence linking aflatoxin ingestion to human hepatocellular carcinoma (HCC); (2) strong evidence of synergy between aflatoxin biomarkers and chronic infection with hepatitis B virus in establishing risk of HCC; (3) failure to find an association between H. pylori serology and stomach cancer risk; (4) the absence of an inverse association between antioxidants and fatal stroke; and (5) the first comprehensive and systematic evaluations of smoking-related cancer incidence and mortality in China. We propose to continue to follow this cohort for an additional five years. We will continue to evaluate risk factors for major health outcomes in the cohort, building on previous observations and continuing to exploit the serum and urine banks available for biomarker studies. Although we did not collect buffy coats for genetic studies on cohort members, we have demonstrated that the stored serum samples contain sufficient cells for conducting selected PCR-based genetic studies. Among the scientific goals for the next five years are: (1) to continue to evaluate the aflatoxin/HCC association and to assess the impact of sequence variations in genes involved in aflatoxin metabolism (GSTM1 and EPHX) in modifying risk; (2) to continue to assess the role of H. pylori in gastric cancer etiology in Shanghai, and to assess the possible protective effect of tea polyphenols on risk; and (3) to better understand the complex interrelationships among carotenoids, smoking, and lung cancer and to assess the possible risk modifying impact of genes involved in metabolism of smoking-related carcinogens.

Summary: (provided by applicant):Millions of Americans are infected by the hepatitis B virus (HBV)-many of whom have no reason to believe they are infected. There is a need to track down America's millions of HBV victims-as well as a corresponding need for innovative technology to test blood for HBV. HBV is clearly a national medical priority. The overall goal of this project is to further develop and then integrate core sensor and enzyme immunoassay technologies into a novel technique for the rapid and accurate measurement of HBV levels in blood. We are targeting diagnostic (detection) applications as well as quantitative measurement needs (to monitor viral levels and treatment efficacy). The feasibility of our approach was clearly demonstrated during Phase I. The Phase II goal is to demonstrate/validate/optimize the integration of a unique electrochemical measurement method with proprietary electrochemical enzyme immunoassay architecture to produce a new diagnostic/monitoring capability for "real time," cost-effective HBV assessment in an outpatient setting. The product we envision is a disposable HBV test strip that can be read by an inexpensive, small (hand-held) instrument. It would represent a key development in medical diagnostics that would address major domestic and international market needs for low-cost HBV screening and monitoring.

Project Title: ENHANCED T AND B CELL RESPONSES VIA RECOMBINANT PROTEINS Principal Investigator & Institution: Gosselin, Edmund; Assistant Member; Alld Health Education Programs; Albany Medical College of Union Univ Union University Albany, Ny 12208 Timing: Fiscal Year 2001; Project Start 01-AUG-2000; Project End 31-JUL-2004 Summary: (Adapted from Applicant's Abstract) A safe and successful vaccine against HIV will likely require the simultaneous priming of both cellular and humoral immune responses, and will preferentially involve the use of recombinant proteins. Targeting immunogens to Fc gamma receptor type I (FcgRI) on antigen presenting cells (APC) significantly enhances T cell activation in vitro, and antibody production in vivo. In addition, it can also lead to simultaneous priming of both cytotoxic and helper T cell responses. Furthermore, by combining the administration of antigen with cytokines, T cell activation can be further enhanced, and T cell subset development modulated. It has also been demonstrated that targeting antigen (Ag) to FcgRI on APC can eliminate the need for traditional adjuvant, easing difficulties associated with vaccine preparation and distribution. Therefore, developing a strategy which facilitates antigen targeting to APC, and the use of cytokines in vaccines, is likely to have a significant impact on current vaccine technology, in particular as it applies to HIV. We propose to utilize molecular techniques, and FcgRI-specific constructs, to create and test the ability of a prototype two component (modular) immune targeting system to stimulate enhanced humoral, CD4 helper T cell, and CD8 cytotoxic T cell responses in vitro and in vivo. Components will consist of a humanized divalent FcgRI-specific biotin-binding targeting element, and biotinylated functional elements including Hepatitis B Ag, gp120 Ag, and IL-2. The ability of the two component immunogens to modulate human CD4 and CD8 T cell responses in vitro, and murine B cell, CD4 T cell, and CD8 T cell responses in vivo, will be examined. In the latter instance, transgenic mice that express human FcgRI will be immunized with two component immunogens. Following immunization, CD4 and CD8 T cell responses, as well as the generation of Ag-specific antibody will be measured. These studies will provide a novel and safe approach for simultaneously priming humoral and cellular responses in vivo using recombinant proteins. This approach will

Project Title: ETIOLOGY AND PREVENTION OF BLOOD BORNE VIRUSES IN IDUS Principal Investigator & Institution: Hagan, Holly C.; Deputy Director; National Development & Res Institutes Research Institutes, Inc. New York, Ny 10010 Timing: Fiscal Year 2001; Project Start 30-SEP-2001; Project End 31-MAR-2007 Summary: (provided by applicant): The etiology and prevention of blood-borne viral infections in injection drug users (IDUs) have not been fully characterized, and many questions remain regarding which injection practices may result in I infection. Viral hepatitis infections in IDUs are among the most frequently occurring 81ood-bornel l infections in humans; in low HIV-prevalence settings, morbidity and mortality in IDUs attributable to l hepatitis virus infections may exceed that for HIV. Hepatitis C virus (HCV) is highly prevalent in IDU- populations, and is more efficiently transmitted l abouty injection than HIV. Because sexual HCV transmission is relatively rare, it may serve as a highly sensitive biologic marker of direct percutaneous exposure to these infections in drug injectors, and may contribute to understanding the mechanism of transmission of other infections via injection practices. The long-term goal of our research is to advance knowledge of the epidemiology, etiology and-prevention of HIV and hepatitis infections in IDUs. We propose studies that will make new contributions toward our long-term goal: Aim 1. Examine the extent to which HCV prevention education at the Seattle needle exchange program has reduced the risk of HCV infection. Aim 2. Measure the risk of HCV seroconversion associated with specific injection risk behaviors, and calculate the risk of HCV attributable to these practices in the IDUpopulation. Aim 3. Compare reporting of socially-undesirable or stigmatized injection and sexual risk behavior collected by A-CASI to interviewer-administered data collection methods. Aim 4. Assess the feasibility and disease control benefits of HBV and HCV partner notification for IDUs. Aim 5. Study whether changes in hepatitis C reporting laws are associated with increased reporting in IDUs. The significance of this research is its potential contribution to our understanding of the etiology of these l infections, and examines many practical questions related to the effectiveness of public health surveillance and prevention programs.

Principal Investigator & Institution: Behrns, Kevin E.; Associate Professor of Surgery; Surgery; University of North Carolina Chapel Hill Office of Sponsored Research Chapel Hill, Nc 27599 Timing: Fiscal Year 2002; Project Start 01-SEP-2002; Project End 31-AUG-2004 Summary: (provided by applicant): Hepatocytes are unique parenchymal cells that divide and regenerate the liver in response to major injury. This regenerative capacity, however, leads to disordered hepatocyte growth in the chronically injured, cirrhotic liver. Hepatocytes in the cirrhotic liver respond differently to growth control signals. Most hepatocellular carcinomas arise in a cirrhotic liver, providing evidence that cirrhotic hepatocytes have altered growth control behavior. Cirrhosis is a major worldwide health problem that is expected to increase in prevalence because of

Studies

43

increasing alcohol abuse and dissemination of the hepatitis B and C viruses, all major causes of cirrhosis. In an earlier proposal (K08), we hypothesized that cirrhotic hepatocytes would be less sensitive to apoptosis. Indeed, studies confirmed that cirrhotic hepatocytes are less responsive to multiple apoptotic agents including tumor necrosis factor a (TNFalpha), transforming growth factor beta (TGFbeta), and ultraviolet-C irradiation (UV-C). The resistance to TGFbeta-induced apoptosis is of special interest because this cytokine is a known inhibitor of hepatocyte growth, and it is present in high concentrations in the cirrhotic liver. The mechanisms by which TGFR induces hepatocyte apoptosis are not well known, but our studies in primary normal mouse hepatocytes suggest that this occurs through a caspase-8 dependent mechanism that requires the generation of reactive oxygen species, depolarization of the mitochondria with cytochrome c release, and caspase-3 activation. This is the first demonstration of caspase-8 dependence. The mechanisms that inhibit this pathway in cirrhotic hepatocytes are unknown, but may involve other TGFR-activated pathways such as the Smad signaling pathway. We hypothesize that the Smad signaling pathway is necessary for hepatocyte apoptosis, and that defects in this pathway are present in cirrhotic hepatocytes. Alterations in the Smad signaling pathway may alter pro- or antiapoptotic factors that govern the cellular balance between survival and death. In this proposal, we aim to determine if the Smad signal transduction pathway is necessary for TGFbeta-induced hepatocyte apoptosis. In addition, because cirrhotic hepatocytes exhibit resistance to apoptosis that may be due to changes in expression of pro-and antiapoptotic factors, we hypothesize that normal and cirrhotic hepatocytes differ in their gene expression profiles. We propose to identify and characterize differences in gene expression profiles between normal and cirrhotic hepatocytes in response to apoptotic stimuli. Examination of these hypotheses will allow our laboratory to growth both in depth and in breadth, because we will use new microarray technology provided within the UNC Genomics Core and Microarray Facility. We will continue to seek counsel from our K08 mentors (Drs. David Brenner and Lola Reid) and use liberally the UNC Center for Gastrointestinal Biology and Disease for core facilities such as the Molecular Imaging Core.

Project Title: HBV DIPSTICK FOR RESOURCE-LIMITED BLOOD BANKS Principal Investigator & Institution: Lee, Helen H.; Diagnostics for the Real World, Ltd 50 Mounds Rd, Unit 512 San Mateo, Ca 94402 Timing: Fiscal Year 2002; Project Start 16-SEP-2002; Project End 31-AUG-2003 Summary: (provided by applicant): According to WHO statistics on blood safety, 80 percent of the world's population has access to 20 percent of the world's safe blood supply. However, more than 20 percent (13,000,000 units) of the world blood supply is not tested for the three major transfusion-transmissible infections: HIV, HBV and HCV. Transfusion of unsafe blood accounts for 8-16 million hepatitis B virus infections. If inexpensive, rapid, improved dipsticks with sensitivity comparable to EIA were developed for blood screening, it would greatly improve the safety of the blood supply in developing countries.The overall aim of the project is to develop a HBsAg dipstick assay with high sensitivity, designated as the reflex diagnostic. The test can be used in developed countries under circumstances where an immediate result is required. For the developing countries, we propose that this test be integrated into a triplex test (HBV, HIV & HCV) and used as the initial step of pre-donation screening in high prevalence countries. The associated second step is to use the HBsAg reflex diagnostic test in order to identify the agent responsible for the positive Triplex test result.The specific aims of Phase I are to optimize the reagents in order to produce a prototype with sub-nanogram sensitivity and to evaluate the assay in 50 HBV-positive samples.

Project Title: HBV INDUCED LIVER PATHOGENESIS Principal Investigator & Institution: Siddiqui, Aleem A.; Professor; Microbiology; University of Colorado Hlth Sciences Ctr P.O. Box 6508, Grants and Contracts Aurora, Co 800450508 Timing: Fiscal Year 2001; Project Start 01-APR-1996; Project End 31-MAR-2006 Summary: (provided by applicant): Hepatitis B virus infections are one of the leading causes of chronic hepatitis. Infection results in a broad range of clinical symptoms from mild, nonapparent disease to fulminant hepatitis to hepatocellular carcinoma. Due to lack of in vitro infection system for HBV, the events of infectious processes are poorly understood. HBV encodes a regulatory protein termed HBx. While many functions have been attributed to HBx, a clear picture of how this protein participates in establishing infectious process has not emerged. In this competing renewal grant application, the focus of our study will be on the detailed characterization of HBx s association with mitochondria and exploring the functional consequences of that association. First, we propose to identify the mitochondrial targeting domain within HBx protein. Using those mutants, which fail to associate with mitochondria, further characterization of various possible functions of HBx within mitochondria will be investigated. These include, the ability of HBx via its interaction with the outer membrane channel VDAC to alter

Alteration of these functions will be correlated with induction of gene expression via NF-kB, AP-1, NF-AT and STAT-3 transcription factors. The results of these studies will delineate the molecular mechanisms in the induction of HBV-induced liver disease pathogenesis including hepatocellular carcinoma.

Project Title: HBV PREVENTION FOR HOMELESS AT-RISK FOR HBV/HCV/HIV Principal Investigator & Institution: Nyamathi, Adeline M.; Professor and Associate Dean; None; University of California Los Angeles 10920 Wilshire Blvd., Suite 1200 Los Angeles, Ca 90024 Timing: Fiscal Year 2003; Project Start 01-AUG-2003; Project End 30-JUN-2008 Summary: (provided by applicant): Nationwide, homeless populations are at risk for HIV infection due to disproportionate use of injection drugs, unprotected sexual activity, prostitution and victimization. Infection with the Hepatitis B Virus (HBV) and the Hepatitis C Virus (HCV) is high among homeless adults as they share risk factors with HIV. Hepatitis A Virus (HAV) is also high among populations vulnerable to HBV, HCV, and HIV as modes of transmission for HAV overlap with those of HBV, HCV, and HIV. Thus, education and screening programs for HAV, HBV, HCV, and HW, combined with vaccination programs for HAV and HBV, can significantly decrease Hepatitisrelated morbidity and mortality. However, homeless persons, many of whom may be contending with drug and alcohol abuse and unemployment, and live in a disorganized world with little access to health and social services, are often non-compliant. In this prospective two group quasi-experimental design, we will evaluate with approximately 1000 sheltered men and women in the Skid Row area of Los Angeles, the effectiveness of a theoretically-based HAV/HBV vaccination intervention focused primarily on completion of the combined Twinrix HAV/HBV vaccination series and secondarily on risk reduction of HAV, HBV, HCV, and HIV. We will also collect data on the relative cost of each of these programs in terms of completion of HAV/HBV vaccination, the cost effectiveness of improving vaccination completion, the cost per sero-protected case, and the cost per infection prevented. Once determined eligible, participants will be randomized by shelter into one of two programs: a Nurse Case Managed Plus Incentive and Tracking (NCMIT) program and a Standard Plus Incentive and Tracking (SIT) program. The proposed study is innovative in that the comparison of the SIT and NCMIT programs will allow us to look at the effect of a standard intervention combining brief education, incentives and tracking with that of a similar intervention that also includes nurse case management on completion of the HAV/HBV vaccination. Participants in the two programs will receive the 3-series vaccination by trained research nurses at the study clinic over six months, along with either the NCMIT, or the SIT program. All participants will be assessed at baseline and six- and twelve-month followup using a battery of psychosocial, behavioral, health and physical status, as well as HAV, HBV, HCV, and HIV sero-status measurements. This proposed study supports the National Drug Abuse Research Initiative as it is focused on assessing the effectiveness of intervention programs promoting the prevention of medical consequences of HAB, HBV, HCV, and HIV in homeless and drug abusing populations.

Project Title: HBV, HCV, CMV & HHV-8 IN HIV POSITIVE WOMEN IN THAILAND Principal Investigator & Institution: Lallemant, Marc J.; Immunology/Infections Diseases; Harvard University (Sch of Public Hlth) Public Health Campus Boston, Ma 02460 Timing: Fiscal Year 2001; Project Start 01-SEP-2000; Project End 31-JUL-2003 Summary: (adapted from abstract) The Harvard School of Public Health's Perinatal HIV Prevention Trial, Thailand study (PHPT) and Thailand's recently established National Data Center for AIDS Vaccine Development (NDCAVD) at Mahidol University's Institute for Population and Social Research have combined efforts to strengthen Thailand's research capacity in the areas of data management and statistics within the context of clinical trials. The specific aims of this proposal are to investigate the epidemiology of four viral infections -- Hepatitis B (HBV), Hepatitis C (HCV), Cytomegalovirus (CMV), and Human Herpes Virus-8 (HHV-8) -- in relation to HIV among a large representative sample of pregnant Thai women. These viruses were chosen for their public health importance or their theoretical/known associations with HIV. This study plans to: 1) determine the seroprevalence of each infection and associated risk factors in HIV+ and HIV- pregnant women; 2) determine the rates of transmission of these viruses and risk factors for transmission in HIV+ women who are not breast feeding; 3) explore the relationship of perinatal HIV transmission to these other viruses; and 4) determine whether co-infection by these viruses are prognostic risk factors for progression of HIV disease in mothers and children. The sera from 35,000 women screened for HIV within the PHPT are available for testing. All HIV-positive women, as well as a randomly selected group of HIV-negative (stratified by urban/rural residence and age), will be screened for these four viruses. All infants born to coinfected (HIV and another virus) mothers will also be tested for the corresponding virus. Sociodemographic and behavioral data from all women, the HIV status of the infants and progression data from HIV-infected children are available from the PHPT. NDCAVD will perform all necessary data management and collaborate in the analysis and interpretation. As a retrospective substudy, this project will provide appropriate training for NDCAVD researchers in the data management of clinical trials, as well as answer some important questions regarding the association of these viruses with HIV and perinatal transmission.

Project Title: HCV GENOMIC VARIABILITY IN HIV INFECTED HEMOPHILIACS Principal Investigator & Institution: Sherman, Kenneth E.; Associate Professor; Internal Medicine; University of Cincinnati 2624 Clifton Ave Cincinnati, Oh 45221 Timing: Fiscal Year 2001; Project Start 01-JUN-2001; Project End 31-MAY-2005 Summary: Hemophiliacs with symptomatic disease are multiply exposed to blood products including factor concentrates to correct the Internet clotting factor deficiencies. Prior to routine use of heat inactivation and screening of donor blood for specific viral pathogens, hemophilia patients were routinely exposed to, and infected with, viruses such as hepatitis B (HBV), hepatitis C (HCV) and human immunodeficiency virus (HIV). Cohort studies in hemophiliacs suggest several clinically and scientifically important findings that warrant further detailed investigation including; a) Liver disease progression may be altered in hemophiliacs infected with HCV with more rapid progression to liver failure and death; b) The source of infection from large pools of concentrate that were potentially infected by multiple discreet donors leads to a high

risks of mixed infection represented by both genotype and quasi species heterogeneity; c) The HIV coinfected hemophiliacs may have different clinical outcomes and an altered immune response may facilitate our understanding of the underlying process of mutant virus selection, and the associated clinical outcomes. The overall goals of this proposal include the study and characterization of the genomic RNA of HCV in infected hemophilic patients with and without confection with HIV. In the retrospective Phase 1, we utilize the NCI Multi center Hemophiliac Cohort Study serum bank database to study the relationship between progression to decompensated liver disease and quasi species variability in the viral envelope hyper variable and core domain. Heteroduplex analysis will be used to rapidly screen samples from index patients and matched controls using samples longitudinally collected over a 10 year or longer period of time. Peptides will be produced from unique quasi species and these peptides will be evaluated for their function as CTL epitomes. Phase 2 involves the initiation and performance of a clinical intervention trial designed to determine variable kinetic response rates to PEG-interferon+ribavirin between hemophiliacs with HCV alone vs HCV/HIV coinfected subjects. Quasi species populations will be modified/cloned, sequencing will be performed to generate families of closely related core peptides that will be studied for their ability to bind and stimulate an immune response. Treatment nonresponders will be followed in a prospective cohort study for up to 3 additional years so that the evolution of the virus, and its associated immune response in this group can be evaluated.

Project Title: HCV IN ALCOHOLICS Principal Investigator & Institution: Wands, Jack R.; Professor of Medicine; Rhode Island Hospital (Providence, Ri) Providence, Ri 02903 Timing: Fiscal Year 2003; Project Start 01-DEC-1993; Project End 30-JUN-2007 Summary: (provided by applicant): Chronic hepatitis C (HCV) infections are common in alcoholics with or without liver disease contributing to significant morbidity and mortality. The reasons for high rates of persistent viral hepatitis infection are unknown but may partially relate to the effects of alcohol on the humoral and cellular immune response to viral structural and nonstructural proteins. We established an animal model system of HCV specific antibody stimulation, CD4+ proliferative response, and CD8+ CTL activity in the context of genetic immunization to test this hypothesis. We plan to do the following: Specific Aim #1 - Further establish the differential effects of ethanol on the immune response(s) to HCV structural and nonstructural proteins in the context of genetic immunization with respect to: a. Assess variations in CD4+ T cell proliferative activity particularly against HCV core, NS3, NS3 helicase, NS4, NS5A and NS5B proteins. b. Evaluate Th1 and Th2 responses to determine if ethanol consumption shifts the immune response from the Th1 to Th2 phenotype. c. Characterize CD8+ CTL precursor frequency and function including possible differential effects of ethanol at the epitope level. d. Examine CTL activity in vivo against HCV derived peptides using an animal model of tumor growth. e. Determine the duration and reversibility of ethanol effects on CD4+ and CD8+ T-cell responses by crossover feeding studies with an isocaloric control diet. Specific Aim #2 - Develop approaches to augment and/or amplify humoral and cellular immune responses generated by DNA immunization in the setting of chronic ethanol administration, a. Explore whether systemic administration (murine and human IFN-a2, or pegylated IFN- a2) is more effective than local administration of cytokine expression construct (IL-2, GM-CSF, IL-12) at the site of gene delivery with respect to augmentation of the humoral and cellular immune

response(s) to HCV structural/nonstructural proteins. b. Determine the value of coimmunization with CpG motifs as an enhancer of the host B and T cell immune responses. c. Employ chimeric constructs to assess their possible role as a stimulant of virus specific B and T cell activities. Thus, principle long term goals of this application are to develop: a clinical DNA vaccine approach, effective alone or in combination with other antiviral agents (IFN-2a, etc.), to enhance the host immune response in an attempt to eradicate persistent viral infection from the liver in alcoholics; and obtain a clearer understanding of ethanol's effects on the immune response to HCV structural and nonstructural proteins in an experimental animal model system thereby generating principles applicable to chronic alcoholics Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen •

Project Title: HEPATITIS B AND C AMONG HOMELESS ADULTS Principal Investigator & Institution: Gelberg, Lillian; Family Medicine; University of California Los Angeles 10920 Wilshire Blvd., Suite 1200 Los Angeles, Ca 90024 Timing: Fiscal Year 2001; Project Start 01-JUL-2001; Project End 31-MAY-2004 Summary: Applicant's Abstract Persons infected with the hepatitis B virus (HBV) or hepatitis C virus (HCV) are at high risk for serious long-term health problems, and they are potentially infectious to others. Because of the seriousness of these infections, the NIH has developed a national agenda for preventing the spread and consequences of HBV and HCV. This agenda includes early detection, treatment, and prevention efforts for high-risk and infected persons. Homelessness has reached crisis proportions in the US today. Recent research by our team and others suggests that homeless adults in urban areas are a group at particularly high risk for HBV and HCV infections due to high rates of risky drug use and risky sexual behaviors. Despite the apparent high risk, however, there is only limited research on viral hepatitis in this group. We propose to conduct epidemiologic and health services research regarding HBV and HCV in a population-based sample of 500 homeless adults. We will recruit a probability sample of homeless adults with oversampling of injection drug users from 30 shelters and meal programs in the Skid Row area of Los Angeles. Respondents will undergo a two-hour interview (including the Diagnostic Interview Schedule-DIS-IV) and blood draw for hepatitis serology. We will estimate the prevalence of HBV and HCV and identify risk factors for each. We will evaluate whether homeless adults with histories of injection and non-injection drug use, risky sex, serious alcohol or mental disorders, or chronic homelessness have an elevated risk for these infections. We will also conduct health services research in which we will describe the respondents' past history of HBV/HCV testing, awareness of infection status, medical care for HBV and HCV, and willingness to return for HBV/HCV test results. Further, we will identify utilization of medical and non-medical settings to identify sites for future screening, treatment, and prevention efforts. We will provide hepatitis B immunization to those that test negative for hepatitis B. We will bridge the gap between research and prevention by using the Theory of Planned Behavior to understand protective behaviors used by homeless adults to avoid exposure to infectious diseases.

Summary: (provided by applicant): The proposal describes a series of experiments designed to target and track antigen following oral delivery via edible transgenic plants. The overall objective is to enhance both systemic and mucosal immune responses to orally delivered antigen. During the previous grant period we have demonstrated that mice fed potatoes expressing HBsAg make both primary and secondary antibodies responses in serum and anti-HBs IgA responses in mucosal secretions. We have provided transmission electron microscopic evidence that the transgenic potato cells harbored unusual membrane-bound bodies that contained circular structures that are approximately 17 nm in diameter. These structures are very similar to the virus-like particles (VLP) found in the serum samples of HBV infected patients and the distended ER vesicles are similar to those produced in yeast expressing HBsAg. These images provide the first ever evidence that in transgenic plants antigen is refined within vesicular structures. We also performed a successful double-blind placebo controlled Phase 1 trial to evaluate the safety and immunogenicity of the edible plant vaccine. None of the volunteers who ate nontransgenic potatoes showed changes in anti-HBs antibody titer. However, after volunteers ate transgenic potatoes, serum antibody titers increased in 62% who ate three doses and 53% who ate two doses of transgenic potatoes. Buffering of the stomach pH was not performed nor was any mucosal adjuvant used. This trial firmly establishes that oral vaccination via edible plant vaccines is possible for a non-enteric antigen such as HBsAg. Taken together, these data form a very solid foundation for the studies proposed in this application. In the current application we propose four specific aims designed (1) to improve the expression of HBsAg in transgenic plants, (2) target antigen to M cells in the gut, (3) to track the immune response elicited and (4) to potentiate the immune response to orally administered antigen by use of nontoxic mucosal adjuvants. We have provided significant new preliminary data and we believe that these provide strong documentation of the likelihood of continued success.

Project Title: HEPATITIS B VIRUS E ANTIGEN EXPRESSION Principal Investigator & Institution: Tong, Shuping; Rhode Island Hospital (Providence, Ri) Providence, Ri 02903 Timing: Fiscal Year 2003; Project Start 01-APR-2003; Project End 31-MAR-2005 Summary: (provided by applicant): Hepatitis B virus (HBV) infects nearly 1/10th of the world population and causes severe liver diseases including cancer. The e antigen (HBeAg) is a secreted soluble protein that promotes immune tolerance during perinatal infection and buffers immunity against HBcAg. The corresponding anti-HBe immune response plays a critical role in the clearance of HBV infection. Therefore, following seroconversion from HBeAg antigenemia to anti-HBe, HBV escape mutants with reduced or no HBeAg production often replace wild-type HBV genomes. The core promoter mutants have various nucleotide changes around positions 1750 -1770 of the HBV genome, and the most common mutations at 1762 and 1764 are known to reduce HBeAg expression at the transcriptional level. The precore mutants have nonsense or frameshift mutations in the HBeAg coding sequence and terminate HBeAg expression at the translational level. Considering the critical importance of HBeAg and anti-HBe in shaping the outcome of HBV infection, we wish to uncover novel regulatory mechanisms for HBeAg expression. In this regard, perinatally infected South African patients seroconvert from HBeAg to anti-HBe at a much accelerated pace than similarly infected Asian patients. Interestingly, the South African HBV variants often harbor two or three point mutations near the precore initiation codon. We plan to verify whether

50

Hepatitis B

the mutations cause leaky scanning to reduce HbeAg translation. Second, HBeAg maturation requires double proteolytic cleavage events in the secretory pathway. The first cleavage occurs in endoplasmic reticulum to remove the N-terminal signal peptide of 19 residues. A Val to Phe missense mutation at residue 17 is frequently detected in HBV genomes isolated from seroconverted patients. Since an aromatic residue at the -3 position of cleavage site is forbidden, we will test whether this mutation impairs HBeAg cleavage and secretion. Third, we recently identified several naturally occurring core promoter mutants with wild-type level of HBeAg production. Based on the results of preliminary mapping experiments, we will determine whether the number and position of core promoter mutations influence the level of HBeAg expression, and whether missense mutations in the HBeAg coding sequence also regulate HBeAg level. This study promises to verify and identify novel mechanisms regulating HBeAg expression, which has a major impact on the outcome of HBV infection.

Project Title: HEPATITIS DELTA VIRUS REPLICATION AND PATHOGENESIS Principal Investigator & Institution: Lazinski, David W.; Assistant Professor; Molecular Biol & Microbiology; Tufts University Boston Boston, Ma 02111 Timing: Fiscal Year 2001; Project Start 01-JAN-1997; Project End 31-DEC-2002 Summary: The principal investigator is interested in the mechanisms by which human pathogenic viruses replicate and establish chronic infections. For the past five years, such interests have been directed toward studies of the replication of hepatitis delta virus (HDV). This subviral human pathogen establishes acute and chronic infections of the liver and uses a helper, hepatitis B virus (HBV), to provide envelope proteins needed for virus assembly. The 25 million carriers worldwide who are chronically infected with HDV suffer a greater incidence of active hepatitis, liver cirrhosis and hepatocellular carcinoma than do those infected with the helper virus alone. The mechanisms responsible for such HDV-associated pathogenicity remain poorly understood and there are currently no effective treatments for HDV-infected individuals. A more detailed understanding of the molecular details involved in HDV replication will be essential if such antiviral therapies are to be developed. In addition to its clinical importance, HDV is also of scientific significance. Unlike all other infectious agents of animals, HDV contains a circular, single-stranded RNA genome that encodes ribozymes. These ribozymes self-cleave multimeric replication intermediates into unitlength species and the resulting termini are joined in a ligation reaction to generate the monomeric circular species. HDV also expresses a protein, the delta antigen, that binds viral RNA to form a ribonucleoprotein (RNP) complex. Like the RNA processing reactions, both the assembly of this RNP and its subsequent incorporation into HBV envelope particles represent essential steps in the viral life cycle that are logical targets for antiviral intervention. Both biochemical and genetic methods will be used in an effort to otter understand the process by which the delta antigen specifically identifies and assembles on its target RNA. Additional experiments are proposed to determine the domain within the helper virus envelope protein responsible for RNP packaging. This will be accomplished by making hybrids with a relative of HBV, duck hepatitis B virus, which is unable to package the HDV RNP. Such experiments may also enable the development of a new animal model useful for the study of HDV pathogenesis. Finally, the principal investigator has previously established a role for host-specific factors in the processing of HDV RNA. To better understand their role in both HDV and host RNA maturation, these factors will be cloned and biochemically characterized. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen

Project Title: HEPATITIS VIRUS, ALCOHOL EXPOSURE AND OXIDATIVE STRESS Principal Investigator & Institution: Hassan, Manal M.; Gastrointestinal Med Oncology; University of Texas Md Anderson Can Ctr Cancer Center Houston, Tx 77030 Timing: Fiscal Year 2001; Project Start 30-SEP-2001; Project End 31-AUG-2003 Summary: (provided by applicant) Hepatitis C virus (HCV) infection and alcohol abuse are the 2 major risk factors for hepatocellular carcinoma (HCC) in this country. The higher prevalence of HCV infection in the general population has resulted in a significant increase of the incidence of HCC in the United States. Although both HCV and alcohol can independently induce liver disease, exposure to both agents may accelerate the course of liver pathology and/or lead to more severe injury. The mechanism underlying the synergistic effect of HCV and alcohol intake is not well understood. One hypothesis is that both HCV and alcohol intake may contribute to chronic hepatitis, cirrhosis and subsequent liver cancer through enhanced oxidative stress. It is known that alcohol could induce oxidative stress and lipid peroxidation. Interestingly, a recent study has reported that HCV encodes a selenium (Se)-dependent antioxidant enzyme, glutathione peroxidase, GPx, and GPx may have a regulatory role in HCV replication. The virus-induced overexpression of GPx may lead to a decreased level of Se in the host due to the competition of HCV for Se. In fact, patients with HCV have been shown to have a significant decline in their serum Se. On the other hand, the hepatotoxicity of ethanol and its associated malnutrition will further reduce the cellular Se level. This additive decline in the Se level will make the cell more susceptible to reactive oxygen species (ROS). Previous studies have shown an association between oxidative DNA damage and either alcohol exposure or chronic viral infection. It seems that chronic HCV infection may lead to an increased ROS, overexpression of GPx and reduced serum level of Se. When the Se-GPx level is low, the virus will be more provoked for replication, leading to a higher viral load in the infected cell. Eighty newlydiagnosed HCC patients will be recruited from University of Texas MD Anderson Cancer Center (UTMDACC). The current project will explore the effect of dietary selenium intake and its interaction with HCV and alcohol intake in HCC in a casecontrol study. Eighty healthy individuals (first control group), matched with cases by age, sex and ethnicity, will be recruited from the patients non-blood relatives and friends from UTMDACC. To have a control group with comparable prevalence of HCV infection, 80 patients with liver cirrhosis, who have no evidence of HCC (second control group), will be recruited from Baylor College of Medicine. Information on alcohol intake, dietary Se intake and other risk factors will be collected by a questionnaire. The frequency and profile of hepatitis B virus (HBV) and HCV infection will be determined by measuring serum HBsAg, anti-HBC, anti-HCV, and HCV-RNA. Oxidative stress will be evaluated by measuring the levels of serum Se, GPx activity, lipid peroxides, and 8hydroxy-deoxyguanosine (8-OH-dG), a marker of oxidative DNA damage. The expression of GPx and the level of 8-OH-dG will also be measured in tissue samples from cirrhotic and HCC patients. Serum Se, GPx activity, lipid peroxides and oxidative DNA damage will be measured in relation to HCV and alcohol intake history. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen

Hepatitis B

Timing: Fiscal Year 2001; Project Start 25-SEP-1999; Project End 31-AUG-2003 Summary: Hepatitis C virus (HCV) infection is common in young injection drug users in San Francisco even though most use sterile syringes. HIV infection is relatively uncommon, and may be contained by the use of sterile equipment. We propose an epidemiological and ethnographic study to investigate this anomaly, and to study HIV and hepatitis infections in young injectors. First, we will examine HIV infection crosssectionally in 1200 injectors aged 29 and under. We will explore risk factors for prevalent HIV infection in this needle exchange-using population. Second, we will carry out a prospective cohort study of HCV seroconversion. The principal aim of the proposed research is to estimate the seroconversion rate for HCV in the young injector population and to determine the reasons for seroconversion. In particular, we will examine the sharing of drug doses and of injection equipment other than syringes as the main reason for ongoing HCV transmission. We will accrue a cohort of 300 HCV seronegative injectors from among the 1200 persons screened and will follow them for one year. We will record HCV seroconversion prospectively. We will also identify individuals with early HCV infection, using a viral RNA amplification technology. Third, we will carry out a randomized controlled trial of a method to improve vaccination against hepatitis B virus (HBV) in young injectors. We will randomize eligible cohort members to either an accelerated vaccine schedule, which may be effective in achieving rapid immunity in young IDUs, or the standard schedule, and will study the development of immunity. Fourth, because little is known about detailed injection and sharing practices among young injectors, we will complement the epidemiological studies with an ethnographic investigation of the injecting practices of street-based youth in their natural context. We will examine how the moral economy of mutual dependency in a street-based youth culture promotes frequent paraphernalia sharing among network members, but direct needle sharing between running partners. We will explore aspects of the cultural, economic and social-status determinants of risktaking that may explain the differential HCV and HIV infection rates.

Project Title: HIV DISEASE OUTCOMES IN DRUG USERS IN CLINICAL PRACTICE Principal Investigator & Institution: Moore, Richard D.; Professor; Medicine; Johns Hopkins University 3400 N Charles St Baltimore, Md 21218 Timing: Fiscal Year 2003; Project Start 30-SEP-2003; Project End 30-JUN-2008 Summary: (provided by applicant): In 1998, we were awarded an RO-1 (DA11602) from NIDA to conduct a longitudinal study in HIV-infected persons who have a history of illicit drug use (DU). The major aims of that study were to develop a longitudinal cohort of HIV-infected patients in medical care in order to characterize utilization of the new highly active antiretroviral drug therapies (HAART), and assess the effect of these therapies on HIV disease progression in DUs. We established a comprehensive longitudinal clinic-based cohort of over 4600 HIV infected persons; half of who have a history of DU. Our research suggests that DUs have not received the same level of benefit from HAART as non-DUs. Prior to HAART, there was little difference between DUs and non-DUs in HIV progression. Our research has shown that active DU is a barrier to receiving and adhering to HAART, and achieving effective viral and immunologic improvement on HAART. We hypothesize that the early differences that have emerged between DUs and non-DUs will substantially widen over the next 5 years as HIV resistance to current drugs increases, toxicity limits the use of therapy, and viral hepatitis along with other medical consequences of DU further increase the burden of

morbidity. Because of HAART, HIV is now a chronic illness, and DUs have numerous barriers to stable, chronic disease management. We are optimally situated to assess the core factors that impede successful HIV management as the HAART era matures over the next 5 years, and are submitting a new proposal for a competitive continuing RO-I. We propose the following aims, consistent with our overarching goal of improving the outcomes of HIV infection in DUs: 1) Evaluate virologic, immunologic and clinical HIV disease progression for up to 10 years, 2) Assess the impact of viral hepatitis coinfection, 3) Assess other medical consequences of DU including bacterial infection and STDs, 4) Assess adverse effects of HIV therapy. We offer a productive resource to address our aims that is unique in scope and size, cost-efficient in conducting research, highly relevant to the HIV epidemic as it effects DUs, and fully operational from our prior R01.

Project Title: HIV RISK BEHAVIORS AMONG URBAN NOMAD DRUG INJECTORS Principal Investigator & Institution: Des Jarlais, Don; Director of Research; National Development & Res Institutes Research Institutes, Inc. New York, Ny 10010 Timing: Fiscal Year 2001; Project Start 05-SEP-2000; Project End 31-JUL-2004 Summary: The global diffusion of HIV, hepatitis B and hepatitis C among injecting drug users (IDUs) shows both that they engage in substantial travel and that research is needed on their travel patterns. Previous research makes it clear that IDUs travel regionally, nationally, and internationally, but has not adequately described travel patterns nor the factors that influence IDUs' HIV risk behavior when they travel. Through our street-based research with IDUs in New York City, we have developed considerable familiarity with a large group of highly mobile, young IDUs, self-defined as "urban nomads", who travel frequently and widely throughout the U.S. These urban nomads are often homeless, but are conceptually and behaviorally distinct from "locally homeless" drug injectors who are not geographically mobile. The specific aims include both methodological and substantive objectives: (Aim 1) Analytically describe a large sample (n = 800) of "urban nomad" young IDUs, including their demographics, drug use histories, travel histories, HIV risk behaviors and serostatus. Identify factors associated with (a) HIV risk behaviors and (b) frequency of intercity travel. (Aim 2) Identify patterns of drug use and HIV risk behavior during travel by urban nomad IDUs, including numbers of "person-trips" (a trip by a person to another metropolitan area), the geographic distribution of person- trips where HIV risk behaviors do and do not occur, and factors that differentiate person-trips with and without HIV risk behavior. Aims 1 and 2 will be achieved through interviews with 600 urban nomad IDUs recruited in New York City and 200 urban nomad IDUs recruited at collaborating research sites across the country. (Aim 3) Implement and assess a long-distance telephone follow-up interview system for collecting data from urban nomad IDUs in their travels. Subjects will be intensively prepared to maintain telephone contact with researchers. Longdistance telephone interviewing will be supplemented by referrals to local research studies for HIV counseling and testing, by referrals to syringe exchange programs, and by e-mail and web site communication. (Aim 4) Determine potential biases in loss to follow-up in using these techniques. Estimated biases can then be used to adjust estimates of continuing drug use and risk behaviors. Aims 3 and 4 will be achieved through a cohort study of 300 subjects recruited in New York. Drug use and HIV risk behavior among IDUs are often viewed as local phenomena, with drug practices, risk behaviors and HIV epidemics occurring within defined geographic areas. The proposed research will provide data and research technologies for a complementary perspective

In Phase II an intervention that includes comprehensive testing, counseling, medical deferral, and practical strategies to overcome barriers to follow up care will be designed and pilot tested. During Phase III, the intervention will be evaluated against the standard of care of offering HIV testing done through a randomized controlled trial. Three hundred and forty-four participants will be randomized to receive either the comprehensive testing and facilitated referral intervention which will offer testing for HIV, hepatitis B and C, and the STDs gonorrhea and chlamydia (and trichomonas for women only) or standard of care HIV testing alone and referral for further hepatitis and STD testing. Primary endpoints will be the number of tests performed, the number of test results received, and the degree of follow up medical care obtained for the two groups.

Project Title: HOMELESS YOUTH: STREET CULTURE/SOCIAL NETWORKS/HIVRISK Principal Investigator & Institution: Auerswald, Colette L.; Pediatrics; University of California San Francisco 500 Parnassus Ave San Francisco, Ca 94122 Timing: Fiscal Year 2001; Project Start 11-JUN-2001; Project End 31-DEC-2005 Summary: (Adapted from applicant's description): Rates of risky behaviors in homeless youths are persistently high, resulting in high rates of morbidity, including seropositivity for HIV and Hepatitis B and C. Interventions based on risk-reduction in this population have had limited effectiveness. Recent research emphasizes that removal from the street should be a primary focus of HIV risk-reduction for homeless youths. Studies of risky behaviors in non-homeless youths and in at-risk adults strongly suggest that a better understanding of the relationships within which risk behaviors take place and of the meaning of the risky behaviors to the actors will lead to more effective interventions. The applicant is a pediatrician and specialist in adolescent medicine who has expertise in the ethnographic study of marginalized youths and experience in quantitative behavioral studies of risky behavior in adolescents. The candidate's career objective is to improve the health of marginalized youths, including homeless youths, through multidisciplinary research on the behavioral determinants of the health- related behaviors and barriers to care in this population. In the training phase of the award the applicant will have four primary development objectives: a) to develop further skills in patient-oriented qualitative research, b) to learn to follow longitudinal cohorts of hardto-reach populations, c) to gain additional expertise in the integration of qualitative and quantitative methodologies in the study of adolescent health-related behavior, and d) to learn to analyze social network data in the study of risky behavior. She will pursue her objectives through mentored research experiences. These will be complemented by

focused course work offered by the K-30 funded Advanced Training in Clinical Research program at the University of California, San Francisco. The objective of the research phase of the award will be to conduct a joint ethnographic-epidemiologicalsocial network study to test the findings of her preliminary research. These findings, based on a street-based ethnographic study of youths, suggest that youths pass through stages of a life cycle of homelessness, each of which is characterized by different levels of acculturation to the street and different compositions of their social networks. By demonstrating in a large street-based longitudinal sample that youths in each stage differ according to acculturation and social networks and that these differences are correlated with rates of risky behaviors, we may have a powerful tool for designing interventions. An approach to intervention based on an understanding of these stages has practical implications, including new screening tools, the designing of stage- based services, and the development of intensive programs for the youths who are most susceptible to removal from the street. An understanding of how social network connections promote and prevent risky behaviors would also have significant implications for the designing of interventions with this population.

Project Title: HOST AND VIRAL GENETIC VARIABILITY IN HBV CARRIERS Principal Investigator & Institution: Evans, Alison A.; Assistant Member; Fox Chase Cancer Center Philadelphia, Pa 19111 Timing: Fiscal Year 2001; Project Start 01-JUN-2001; Project End 31-MAY-2006 Summary: Chronic carriers of hepatitis B virus (HBV) are at increased risk for hepatocellular carcinoma (HCC). Worldwide, however, the risk of HCC and other adverse outcomes varies substantially both between and within populations of HBV carriers. The reasons for these differences in the natural history of infection are not known. Our analysis of cohort studies in three endemic populations have suggested that the long term maintenance of high-titer viremia (i.e., equal to or > 1 pg/ml) is an important predictor of HCC. The mechanism behind the maintenance of viremia is, however, not well understood although it is clear that the host immune response plays a key role. In this application, we focus on molecular variants of the virus itself and polymorphisms of human immunoregulatory genes as potential predictive or explanatory factors in maintenance of viremia. We will draw upon established prospective cohorts of chronic HBV carriers in China, West Africa, and AsianAmericans. Our preliminary data support a relationship between deletions in the C ORF of HBV and clearance of active viral replication. In the proposed project we will test this hypothesis and extend our studies of molecular variation of HBV by application of novel statistical methods to sequence data. We will also test the hypothesis that maintenance of HBV viremia is associated with polymorphisms of the vitamin D receptor (VDR) and tumor necrosis factor alpha (TNFalpha) promoter. Allele frequencies for polymorphisms of lesser-studied immunomodulatory genes in our cohorts will be estimated in order to develop hypotheses about their relationship to maintenance of viremia in HBV carriers.

Hepatitis B

Timing: Fiscal Year 2001; Project Start 04-FEB-2000; Project End 31-JAN-2005 Summary: Our long-term goal is to understand the pathobiology of viral hepatitis. Hepatitis B virus (HBV) is the 4th most common infectious agent in humans worldwide. Chronic infection with HBV is tightly associated with the development of liver cancer. The mechanism of how HBV chronic infection is established and its pathogenesis remains to be fully explored. Recently, there has been increasing evidence that HBV chronicity may be influenced by the presence of genetic variants that evolve in patients as liver disease progresses. Since the invention of polymerase chain reaction technology, many HBV sequence variants have been reported. However, a common frustration in the research of HBV variants is that the majority of these reported sequence variants has no known functional significance and does not exhibit a strong phenotype distinctively different from the wild type virus. The most frequent missense mutation found in the HBV core antigen occurs at codon 97 in chronic carriers worldwide (in 83 percent hepatoma patients). Our recent functional characterization of this mutant uncovered a novel and strong phenotype, dubbed an "immature secretion" phenotype. Unlike wild type HBV, the secreted Dane particles of codon 97 mutants contain predominantly the immature form (lower molecular weight) of the HBV DNA genome. In this application, we propose 1) to extend our observation of the "immature secretion" phenomenon from tissue culture to patients and animal models. We also attempt to extend the "immature secretion" phenotype to other viral subtypes prevalent in different geographic locations. 2) to investigate the mechanism of "immature secretion" by both genetic and biochemical approaches. One of the several hypotheses to be tested is that "immature secretion" could be caused by hyper-efficient interactions between wild type envelope and mutant core proteins. 3) Finally, we will compare the infectivity of the highly frequent codon 97 mutants and wild type HBV via in vitro infection assays. Successful completion of this work will help understand the fundamental rules governing HBV morphogenesis and virion secretion, in addition to the important implications for chronic viral hepatitis as well as many other chronic progressive viral diseases.

Project Title: IMMUNE REGULATION OF CNS VIRAL RECRUDESCENCE Principal Investigator & Institution: Bergmann, Cornelia C.; Associate Professor; Neurology; University of Southern California 2250 Alcazar Street, Csc-219 Los Angeles, Ca 90033 Timing: Fiscal Year 2002; Project Start 15-MAY-2001; Project End 31-MAR-2006 Summary: (provided by applicant): A variety of human viruses, including herpes viruses, hepatitis B virus and HIV, produce acute infections followed by persistence or recrudescence. However, the mechanism(s) regulating persistence and recrudescence depend on a balance between viral replication and the host immune response. Viral tropism and antigenic load provide additional determinants in this complex scheme. This proposal examines the contribution of cell mediated and humoral immunity in controlling recrudescence of a neurotropic virus following initial clearance. Infection of immunocompetent mice induces an acute encephalomyelitis, followed by persistence without infectious virus. During acute infection cell mediated immunity, predominantly the CD8+ T cells, are crucial in controlling virus replication within the central nervous system (CNS). However, in the absence of B cells, these effector functions do not suffice to suppress virus to undetectable levels, thereby allowing virus reactivation. Importantly, transfer of anti-viral antibody (Ab) prevents virus reactivation, implicating a crucial role for Ab and/or B cells in controlling persistence. However, analysis of virus specific T cells using class I tetramet technology revealed that the percentage of virus

Studies

specific CD8+ T cells in the CNS is reduced compared to immunocompetent mice. In addition, there is no increase in virus specific T cells during reactivation. These data suggested that CD8+ T cells may be functionally impaired or exhausted due to increased antigen load. This proposal distinguishes between the requirement(s) for potent CD8+ T cell function vs Ab in controlling virus reactivation in a persistently infected host. The contribution of both neutralizing and non neutralizing Ab, Fc receptor (FcR) activity and complement are examined by Ab transfers and using mice deficient in FeR. These experiments will determine the mechanism of Ab mediated prevention of virus reactivation in an Ab deficient milieu. The possibility that the absence of Ab and/or B cells results in defective CD8+ T cell priming, ultimately leading to exhaustion during recrudescence is tested by functional and phenotypic analysis of CD8+ T cells during priming and recrudescence. Intervention via transfer of protective Ab or CD8+ T cells activated in vitro will determine if functionally impaired CD8+ T cells can be overcome. These experiments may have direct implications for therapeutic interventions during persistent viral infections. Finally, virus reactivation will be tested in an Ab deficient mouse with a normal B cell compartment. These experiments will distinguish between the possibilities of an Ab independent effect of B cells and a CD8+ T cell defect related to the absence of B cells. This proposal will provide insight into the immunological regulation of both virus recrudescence and the CNS as a target organ. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen •

Project Title: INITIATION OF HEPATITIS B VIRUS REPLICATION Principal Investigator & Institution: Mclachlan, Alan; Scripps Research Institute Tpc7 La Jolla, Ca 92037 Timing: Fiscal Year 2003; Project Start 15-JUL-2003; Project End 30-JUN-2005 Summary: (provided by applicant): Hepatitis B virus (HBV) infection is a worldwide health problem. It is estimated that there are 200 to 500 million HBV chronic carriers in the world for whom, to date, there is no reliable treatment. HBV causes both acute and chronic liver disease and the estimated relative risk of primary hepatocellular carcinoma (PHC) in chronic HBV carriers is approximately 100 times greater than in uninfected individuals. Therefore, effective treatments for chronic HBV infection are required. In these studies, the mechanism(s) regulating the initial steps in the synthesis of hepatitis B virus (HBV) DNA will be investigated. HBV DNA synthesis is initiated by binding of the viral polymerase to a stem-loop structure, epsilon, located at the 5'-end of the HBV pregenomic RNA. Initially, the first three nucleotides of HBV minus-strand DNA are synthesized utilizing the amino-terminal domain of the polymerase as a primer and the bulge region of epsilon as a template. The HBV polymerase with the covalently attached trinucleotide sequence is subsequently translocated to the DR1 sequence at the 3'-end of the pregenomic RNA. HBV minus-strand DNA synthesis then proceeds by the reverse transcription of the pregenomic RNA. The mechanism(s) regulating the translocation step are unknown. Recently, a regulatory sequence element, phi, located immediately upstream of the DR1 sequence at the 3'-end of the pregnomic RNA that is important for efficient viral replication and is complementary to the 5'-half of epsilon was identified. This finding suggests that the translocation of the minus-strand primer from epsilon to DR1 might be mediated by a conformational change in the pregenomic RNA that brings the primer into proximity with the DR1 sequence at the 3'-end of the pregenomic RNA. The conservation of the complementarity between epsilon and phi in the woodchuck hepatitis virus (WHV) and the duck hepatitis B virus (DHBV) genomes also supports this contention. Therefore, the role of the complementarity between epsilon and phi in regulating HBV replication will be examined directly by mutational analysis of these

sequence elements. This approach is aimed at identifying possible targets for therapeutic intervention in chronic HBV infection. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen •

Project Title: INNOVATIVE FORMULATION

VACCINE

Principal Investigator & Institution: Kitchell, J P.; Director, Biodegradable Implants; Biotek, Inc. 21-C Olympia Ave Woburn, Ma 01801 Timing: Fiscal Year 2002; Project Start 01-AUG-2002; Project End 31-JAN-2004 Summary: (provided by applicant): Hepatitis B (HBV) is a serious viral disease that can result in acute massive hepatic necrosis, chronic active hepatitis, and cirrhosis of the liver. HBV vaccines are commercially available and HBV vaccination is now recommended for all infants, adolescents, health workers and others who may be exposed to the virus through their work. Three HBV vaccine injections are required to generate protective immunity. Compliance depends on completing three visits to the healthcare provider. Incomplete vaccination is common and often attributed to scheduling difficulties. The vaccination success rate could be improved if only one dose were needed for full protection. There have been many attempts to address the need for single dose formulations for vaccines. Kitchell and Crooker (1997) studied the physicochemical properties of alum, the adjuvant used in the approved HBV vaccine, and they made an important observation about the hydration behavior of this material. Their discovery led to a simple and elegant method of formulating alum-adjuvanted hepatitis A vaccine as a single-dose injection giving multiple delayed pulses. This innovative approach to reformulation is also appropriate for the HBV vaccine. BIOTEK believes that it has gained further insight into the techniques needed to prepare a single dose HBV vaccine which provides three discrete pulses of vaccine exposure. The formulation will utilize the established HBV vaccine antigen and adjuvant, and a FDA approved biodegradable polymeric excipient. The specific aims of the Phase I project are to prepare and test in vivo both one month and four month delayed pulse formulations. PROPOSED COMMERCIAL APPLICATIONS: The technology, first directed at an improved hepatitis B vaccine formulation, could be transferred to hepatitis A vaccine and to the childhood DPT vaccination series. One important application in the future may be with an AIDS vaccine, where relaible single-dose protection for high risk populations may be especially important.

Principal Investigator & Institution: Rosenberg, Stanley D.; Professor; Psychiatry; Dartmouth College 11 Rope Ferry Rd. #6210 Hanover, Nh 03755 Timing: Fiscal Year 2001; Project Start 01-SEP-2000; Project End 31-AUG-2003 Summary: (adapted from the applicant's abstract): People with severe mental illness (SMI), and particularly those dually diagnosed with comorbid substance use disorder (SUD), are at extremely elevated risk for several serious blood-borne infections, including HIV, Hepatitis B and Hepatitis C. One third of dually diagnosed clients in many mental health service settings are likely to have one of these infections, and the rate of co-infection is very high. However, the field lacks effective and feasible models for responding to this problem, and neither infected nor high-risk clients receive services that meet authoritative standards. Indeed, infected clients may be the least

59

likely of all people with SMI to receive adequate medical care. By and large, mental health providers are not well informed regarding these issues, and do not systematically provide the necessary interventions to help clients understand and cope with these risks and diseases. Providers do, however, express interest and willingness to respond by increasing staff education and by adding services for their high-risk clients. To date, no such innovation has been reported in any state mental health system, even in those states with known high rates of seroprevalence. Barriers to dissemination and provision of best practices have been identified, and include providers' underestimation of the problem in clients they serve, and confusion about how to best respond to information about clients' risk and infection status. To implement and sustain best practices interventions for this vulnerable group of clients, integrated procedures to change the knowledge, attitudes, training resources and practices of community mental health providers are required. Procedures for dealing with blood-borne pathogens should be structured to be a standard part of multidisciplinary team treatment. They should include a very basic set of evidence based practices for HIV, Hepatitis B and Hepatitis C, including screening, diagnosis, counseling, risk reduction, immunization, linkage with appropriate medical providers, and support for clients through treatment. We propose, in this Exploratory/ Developmental Grant application (R21), to develop an easily disseminated intervention, packaged as a "toolkit" and supported by implementation assistance, to enhance the knowledge, attitudes and practices of typical community mental health providers so that they will achieve sustainable, best practices standards for their infected and at-risk clients.

Project Title: INTERNATIONAL CONFERENCE ON HEPATITIS B VIRUSES Principal Investigator & Institution: Slagle, Betty L.; Assistant Professor; Molecular Virology & Microbiol; Baylor College of Medicine 1 Baylor Plaza Houston, Tx 77030 Timing: Fiscal Year 2001; Project Start 01-JUL-2001; Project End 30-JUN-2002 Summary: (provided by applicant): Infection with Hepatitis B virus (HBV) is still a serious public health problem, with an estimated 300 million chronic carriers worldwide. In recent years, substantial progress has been made in establishing the molecular basis of individual steps in the replication of the virus, revealing its unique status among retroelements. However, immense experimental difficulties, including the lack of appropriate in vivo and experimental, infection systems, have hampered a similarly detailed analysis of the early steps of infection. The limitations have further hindered the fundamental understanding the complex interplay between virus and host and its effects on pathogenicity. This conference is distinct from clinically oriented meetings, and is intended to gather scientists studying different aspects of HBV and related animal model viruses, for joint discussion of the latest conceptual and technical advances. The meeting is organized by Drs. Betty Slagle and Michael Roggendorf, who are assisted by a panel of expert HBV scientists acting as chairpersons for 12 lecture and 2 poster sessions. In addition, it is planned to have a workshop on controversial issues. Session topics will include: transcription; replication; structural proteins and receptors; regulatory proteins; hepatocellular carcinoma; HBV variants and hepatitis delta virus; and persistence, pathogenesis, and immunology. Each session will comprise 4-8 talks, selected from submitted abstracts that are peer-reviewed by the session chairpersons. In the tradition of previous meetings of this series, in addition to the attendance and presentations by senior investigators, graduate students and postdoctoral fellows will be particularly encouraged to participate in the lecture and poster sessions. HBV research is

Project Title: INTERNATIONAL CONFERENCE ON THE HEPATITIS B VIRUSES Principal Investigator & Institution: Tavis, John E.; Molecular Microbiol and Immun; St. Louis University St. Louis, Mo 63110 Timing: Fiscal Year 2003; Project Start 01-AUG-2003; Project End 31-JUL-2004 Summary: (provided by applicant): The 350 million chronic carriers of Hepati tis B Virus (HBV) worldwide are at risk of hepatitis, cirrhosis, and hepatocellular carcinoma. A recombinant subunit vaccine is available, but it has a 5-10% failure rate, and there is no widely effective therapy for HBV infection. The development of effective therapies could be advanced more rapidly by a better understanding of the mechanisms of pathogenesis, the immune response, and function of the proteins involved in HBV replication. This conference will gather about 200 scientists who study different aspects of HBV, animal hepadnaviruses, and Hepatitis Delta Virus for discussions of the latest conceptual and technical advances. This meeting has been held annually since 1985, and is the only basic science HBV and HDV meeting of its kind. The primary goal of this application is to raise funds to support travel grants for junior scientists. The 2003 HBV Meeting will be organized by Drs. Antonio Bertoletti and John Tavis. The meeting will be modeled on the successful traditions of this series: intimate interactions through small size, presentation of work-in-progress, and a focus on training younger scientists. The meeting will have 9 oral sessions, two poster sessions, a keynote speaker, and one workshop. The oral session will be: New Models & Viral Entry, RNA & DNA Synthesis, Assembly, Morphogenesis & Trafficking, Regulatory Proteins and Variants, Immune Responses, Pathogenesis, Hepatitis Delta Virus, Hepatocellular Carcinoma & Oncogenesis, and Antivirals & Immunomodulation. Involvement of women and minorities in leadership positions will be emphasized. Each session will have approximately 7 talks selected through peer-review by the organizers of submitted abstracts. Posters for each topic will be presented in the poster sessions. A theme of the meeting will be to compare and contrast HBV with Hepatitis C Virus (HCV), the other most medically important hepatitis virus. The keynote speaker, Dr. Raft Bartenschlager, will contrast the molecular biology of HCB with that of HBV. The workshop will compare HBV and HCV immunology and pathogenesis. This conference will advance HBV research by introducing ideas from the HCV field, promoting constructive interactions between researchers, encouraging exchange of unpublished data and key reagents, and educating graduate students and post-doctoral trainees.

Project Title: INTERVENTIONS TO INCREASE HBV VACCINATION IN STD CLINICS Principal Investigator & Institution: Zimet, Gregory D.; Associate Professor; Pediatrics; Indiana Univ-Purdue Univ at Indianapolis 620 Union Drive, Room 618 Indianapolis, in 462025167 Timing: Fiscal Year 2002; Project Start 05-SEP-2002; Project End 31-AUG-2007 Summary: (provided by applicant): The objective of this study is to evaluate interventions to increase acceptance of, and follow through with, hepatitis B virus (HBV) immunization among patients attending sexually transmitted disease (STD) clinics in Chicago, IL and Indianapolis, IN. This research will have implications for the

61

design of interventions that may increase HBV vaccine uptake in at-risk groups. The interventions may also be applicable to other STD vaccines as they become available. The first specific aim is to assess the effect of message framing on vaccine acceptance. Prospect theory will be used to guide the development of the message-framing interventions. This theory suggests that positively framed messages (i.e., benefits of getting vaccine) are more effective than negatively framed messages (i.e., dangers of not getting vaccine) in stimulating preventive health behaviors. Research on Prospect Theory and engagement in health behaviors suggests also that the effects may be moderated by other attitudinal factors, including perceived risk of the behavior and degree of involvement in the message. The second aim is to evaluate the effect of provider-based interventions. Prior research suggests that recommendations by health providers are very important in patients' decisions regarding acceptance of healthcare procedures. The third aim is to examine the effect of the interventions on follow-through with the second and third recommended vaccination. During Year 1 of the proposed plan, the message framing interventions will be developed and pilot tested and healthcare providers in Chicago and Indianapolis will be trained in the provider-based interventions. During Years 1-5, 3,344 patients (18 years and older) will be recruited and followed from Chicago and Indianapolis STD clinics during routine medical visits. An audio computer-assisted self-interview (A-CASI) will cover demographics, risk behaviors, and perceived risk associated with vaccination. Subjects then will be randomized to receive a gain-framed, loss-framed, or information only message regarding HBV immunization (also delivered by A-CASI). Upon completion of the message-framing intervention, subjects will be complete additional attitude questions via A-CASI, then will be randomly assigned to one of two provider intervention conditions: 1. vaccine-offered or 2. vaccine-recommended. For both conditions free HBV immunization will be provided by a nurse practitioner. Debriefing interviews will be carried out. Subsequently, postcard reminders will be sent and phone call reminders made for follow-up appointments for those receiving the first and second doses of vaccine. Outcome measures of interest include: (1) acceptance vs. rejection; (2) compliance with two doses vs. one dose only; and (3) completion of immunization vs. two doses only. The relationships of the interventions, socio-demographics, attitudes and behaviors to the outcome measures will be assessed with multiple logistic regression (MLR) and path analysis via structural equation modeling.

Project Title: JOHNS HOPKINS ADULT AIDS CLINICAL TRIALS UNIT Principal Investigator & Institution: Flexner, Charles W.; Associate Professor; Medicine; Johns Hopkins University 3400 N Charles St Baltimore, Md 21218 Timing: Fiscal Year 2001; Project Start 01-JAN-2000; Project End 31-DEC-2004 Summary: (adapted from applicant's abstract): Johns Hopkins University has had an ACTU since its inception in 1986. The Unit is administratively within the Division of Infectious Diseases as a component of the Johns Hopkins HIV Care Program, but it is configured to make maximum use of relevant institutional resources with investigators from multiple departments and divisions including Pharmacology, Neurology, Ophthalmology, Gynecology, Pathology and Internal Medicine. The Hopkins ACTU has provided leadership to the ACTG scientific agenda and has provided HIV clinical trials to Baltimore, a city that ranks ninth among metropolitan areas in AIDS rates. The performance record for the last grant cycle shows average enrollment, data performance and a rank of No. 3 in scientific contributions. Assets of this ACTU include leadership and scientific expertise in virology (B. Jackson), immunology (H. Lederman, T. Quinn, R.

Bollinger), quality of life assessment (A. Wu), neurology (J. McArthur), pharmacology (C. Flexner), CMV retinitis (D. Jabs), and mycobacteriology (R. Chaisson). This unit has a subunit in the prison system, has developed an ACTG study of tuberculosis in Haiti and has high enrollment of injection drug users and African-Americans. This application proposes to continue a scientific portfolio that has depth and diversity to support the ACTG scientific agenda and a clinical trials program that includes good data performance and the enrollment of high priority participants. All current investigators will continue in their present roles as will the three advanced technology laboratories. Three new investigators, Dr. R. Siliciano (latent reservoirs of HIV), Dr. Richard Moore (HIV outcomes, cost and cost effectiveness), and Dr. David Thomas (hepatitis C coinfection) will be added. Preference will be given to protocols that reflect emphasis areas of the Hopkins ACTU, especially pharmacology, neurology, immunology, mycobacteriology, hepatitis C, long-term outcomes (quality of life and cost analyses) and simplified ART regimens (to better serve the patients). There will be emphasis on enhanced enrollment with a new peer recruiter and a new subunit to increase the catchment area. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen •

Project Title: LIVER CANCER CONTROL AMONG NORTH AMERICAN CHINESE Principal Investigator & Institution: Taylor, Victoria C.; Fred Hutchinson Cancer Research Center Box 19024, 1100 Fairview Ave N Seattle, Wa 98109 Timing: Fiscal Year 2003; Project Start 25-JUL-2003; Project End 30-JUN-2007 Summary: (provided by applicant): Little is known about the disease prevention behavior of Chinese in North America, and few studies have addressed cancer control in this group. However, Chinese American men and women are four times more likely to be diagnosed with liver cancer than their non-Latino White counterparts. This excess risk is attributable to high rates of hepatitis B virus (HBV) infection combined with low levels of hepatitis B vaccination coverage. The goal of this research is to increase the proportion of less acculturated Chinese adults who have been tested for HBV (and, therefore, either have been vaccinated, are screened for liver cancer, or know they are immune to the disease). Objectives are to: obtain qualitative and quantitative information about the liver cancer prevention behavior of Chinese Americans and Canadians; develop a culturally and linguistically appropriate outreach intervention targeting hepatitis B and liver cancer among Chinese; and conduct a randomized controlled trial to evaluate the effectiveness, feasibility, and acceptability of the intervention program. To increase the generalizability of our findings, the research will be conducted in two cities: Seattle, Washington and Vancouver, British Columbia. The project will emphasize community involvement. PRECEDE and qualitative methods (i.e., forty in-depth interviews and eight focus groups) will be used to develop a quantitative survey instrument as well as intervention components. Six hundred Chinese men and women aged 18-64 who have not been serologically tested for HBV will be identified from a community-based survey of 1,200 individuals, and randomized to intervention or control status. Individuals in the experimental group will receive an outreach worker intervention (which will include a home visit and follow-up telephone call, tailored counseling and logistic assistance, and the use of audiovisual and print materials). Outcome evaluation will be based on data from a follow-up survey as well as medical record verification. If effective, our outreach intervention could be used by health care facilities and community organizations serving less acculturated Chinese in North America.

Project Title: LIVER-TARGETED PRODRUGS FOR THE TREATMENT OF HEPATITIS B Principal Investigator & Institution: Van Poelje, Paul D.; Metabasis Therapeutics, Inc. 9390 Towne Centre Dr, Ste 200 San Diego, Ca 921213026 Timing: Fiscal Year 2001; Project Start 01-AUG-2001; Project End 31-JUL-2002 Summary: (provided by applicant): The synthesis and characterization of novel prodrugs of the antiviral nucleosides acyclovir, penciclovir, and lamivudine are proposed with the purpose of identifying an agent with improved efficacy in the treatment of hepatitis B. The proposed prodrugs are designed to target the nucleosides selectively to the liver in their monophosphate form, and to enhance significantly the formation of the corresponding nucleoside triphosphates (NTP's), which are potent inhibitors of hepatitis B virus (HBV) polymerase. Enhanced hepatic NTP formation is likely to confer more rapid and complete suppression of HBV replication, and consequently to prevent the emergence of drug resistance, a major problem with current therapies. Studies are planned that will address (a) prodrug activation by a liver-specific enzyme (b) prodrug activation and phosphorylation in isolated hepatocytes and (c) prodrug pharmacokinetics and hepatic NTP generation in the rat. A key indicator for the success of the prodrug approach and its therapeutic potential is the temporal profile of hepatic NTP levels in vivo relative to parent nucleoside. A favorable profile will provide the impetus for additional studies envisaged for phase II of the proposal: the assessment of efficacy in animal models of HBV and the toxicological evaluations necessary to support clinical development.

Project Title: MEASLES VIRUSES WITH ADDED VACCINE SPECIFICITIES Principal Investigator & Institution: Cattaneo, Roberto; Professor of Biochemistry & Molecular Bi; Mayo Clinic Rochester 200 1St St Sw Rochester, Mn 55905 Timing: Fiscal Year 2004; Project Start 01-DEC-2003; Project End 30-NOV-2007 Summary: (provided by applicant): The live attenuated measles vaccine has an outstanding efficiency and safety record and induces enduring immunity. We hypothesize that a currently used measles virus (MV) vaccine strain is an ideal platform for the development of pediatric vaccines eliciting immunity against other pathogens. We will test two propositions of this hypothesis: first that vectored MVs can protect against infection with another pathogen. Second, that they can elicit a strong immune response against other human pathogens whilst maintaining vaccine function against measles. To test the first proposition we will complete the production of a panel of vectored MV with the potential of inducing strong humoral and/or cellular immune responses to a mouse pathogen. We will take advantage of the detailed knowledge of the determinants of the immune response against the Daniels strain of the picornavirus Theiler. Proteins or peptides of this virus will be expressed in MV vectors with different scopes: induction of high neutralizing antibody titers, of specific cytotoxic T lymphocytes, or of both. The quality and strength of the immune response and the efficiency of protection against challenge with Theiler virus will then be measured in genetically modified mice permissive for MV infection. The correlates of vaccine efficiency will be established. To test the second proposition we will produce recombinant MVs with the potential of eliciting strong and sustained immune responses against two human pathogens for which an inexpensive vaccine requiring a single immunization is highly desirable. Recombinant MV expressing the surface antigen of

64

Hepatitis B

the hepatitis B virus at different levels will be used to define the expression strategy most effective in inducing a strong humoral immune response. Recombinant MV expressing different proteins and CTL-inducing peptides of the hepatitis C virus will also be produced, and the strength of the induced humoral and cellular immune responses measured. Those viruses inducing the strongest immune response against hepatitis B and hepatitis C virus components in genetically modified mice will be inoculated into juvenile macaques. Their efficacy in protecting these primates against wild type measles infection and in inducing an immune response against the additional pathogen will be measured.

Project Title: MECHANISMS OF CHRONIC HEPATITIS B INFECTION Principal Investigator & Institution: Milich, David R.; President; Vaccine Research Institute of San Diego San Diego, Ca 92109 Timing: Fiscal Year 2001; Project Start 01-MAY-1984; Project End 31-MAR-2006 Summary: (Adapted from applicant's abstract): The hepatitis B virus (HBV) is a major cause of infectious liver disease throughout the world. There are 1.2 million carriers of HBV in the U.S. and approximately 300 million worldwide. Neonatal HBV infection is rarely cleared and as many as 90 percent of perinatally infected children become chronically infected. Therefore, in addition to worldwide vaccine programs to prevent new infections, methods for treating HBV chronic carriers will be necessary to eradicate this disease. This application is focused on understanding the mechanisms responsible for inducing and maintaining chronic HBV infection, and specifically the role of HBV nucleoprotein antigens, the nucleocapsid (HBcAg) and the secreted non-particulate HBeAg. The specific aims are addressed through the use of HBc/HBeAg-expressing and HBV replicating transgenic (Tg) mice, the eight recently developed HBc/HBeAg-specific T cell receptor (TCR)-Tg lineages and various combinations of "double and triple-Tg" hybrids. The specific aims are: (1) production and characterization of TCR-Tg lineages; (2) development of models to explore the relationship between chronicity and perinatal infection; (3) examine the potential of the secreted HBeAg to elicit and maintain immune tolerance and promote chronicity; (4) explore mechanisms that allow HBc/HBeAgspecific CD4+ T cells to escape tolerance induction and co-exist with viral antigens; (5) examine mechanisms by which residual (i.e., non-tolerized) HBc/HBeAg-specific CD4+ T cells cause liver injury; and (6) use the models of liver injury to screen HBc/HbeAgspecific immunotherapies potentially useful in the treatment of chronic infection. It is anticipated that the results of these studies will have diagnostic, therapeutic, and vaccine applications and will provide a better understanding of basic immune mechanisms responsible for viral persistence and clearance in chronic HBV infection.

A critical early step in viral replication is the assembly of a ribonucleoprotein (RNP) complex comprised of the viral reverse transcriptase (RT) and

Studies

65

pgRNA, which triggers both the assembly of nucleocapsids, the site of viral DNA synthesis, and the initiation of reverse transcription, which is primed by RT itself (the protein priming reaction). Through a complex multi- step reverse transcription pathway, the pgRNA is subsequently converted, within the context of the nucleocapsids, into the characteristic, relaxed circular DNA genome which can then exit the cell. The broad, long term objective of this proposal is to elucidate the molecular mechanisms of hepadnavirus replication, focusing on the virus-cell interactions critical for viral assembly and replication. The first specific aim is to identify host factors required for the interaction between RT and pgRNA and for protein priming. A combined approach based on physical association with RT, pgRNA and viral particles and biochemical fractionation and reconstitution will be used for this purpose, taking advantage of an established cell-free system that can recapitulate these early events in viral replication. The second aim is to elucidate the determinants on both RT and pgRNA responsible for specific RNA-protein interaction. Optimal conditions for RTbinding and crosslinking will be sought. The RT and contact sites in the RNP complex will then be identified through protein and RNA sequence analyses. This will, in turn, guide further mutagenesis studies to elucidate the specific requirements of RT and pgRNA for RNP formation. The third aim is to determine the requirements for individual steps of the viral reverse transcription pathway, using a recently developed synchronized viral replication system. Nucleocapsids from every stage of reverse transcription will be isolated to determine their structural changes, which accompany, and may be required for, the progression of viral DNA synthesis. Furthermore, specific host factors required for the different steps of reverse transcription will be identified by (1) carrying out viral DNA synthesis with the isolated nucleocapsids under cell-free reconstitution conditions and (2) treating virus-producing cells, at different stages of reverse transcription, with agents that target candidate host factors. The accomplishment of these goals should reveal novel cellular, as well as viral, targets for developing effective antivirals which is urgently needed for the treatment of over 300 million patients worldwide infected with the hepatitis B virus, who are at great risk of developing hepatic failure and hepatocellular carcinoma. In addition, studies on how host factors facilitate viral replication will also provide important insights into the normal cellular functions of these factors.

lymphocyte activity, lymphocyte proliferation and advanced flow cytometry, and defining and validating immunologic markers as surrogate markers independent of CD4 and HIV RNA. Finally, this unit has contributed to the Pharmacology Committee with the evaluation of targeted- concentration control studies and the correlation of drug exposure with treatment response and failure parameters. The Miami ACTU will actively participate in HIV Disease RAC efforts and provide expertise to address study treatment strategies for initial therapy, treatment options for virologic failure and utilization of phenotypic and genotypic assessments to direct subsequent therapy and treatment intensification. The Miami ACTU will also bring expertise in the areas of hepatitis B and C pathogenesis and treatment, metabolic complications of HIV-1 protease inhibitor pathogenesis and treatment, HIV dementia pathogenesis and treatment and peripheral neuropathy pain assessment, Kaposi sarcoma (KS) pathogenesis, intensive immunologic monitoring and definition, and validation of immunologic determinants of treatment response. The Miami ACTU plans to enroll 100 subjects per year across AACTG studies and 70 patients into AACTG substudies, including but limited to Compartmental, Virology, Viral Dynamics, Pharmaceuticals, Metabolic, Neurologic, Women's Health and Adherence and Outcomes substudies. With a support system in place for the long-term follow-up of patients, the Miami ACTU anticipates to enroll approximately 80 patients into the ALLRT study (ACTG 5001) over a 2-year period.

Project Title: MODELING VIRAL AND T LYMPHOCYTE DYNAMICS Principal Investigator & Institution: Perelson, Alan S.; Staff Member; None; University of Calif-Los Alamos Nat Lab Ms G758 Los Alamos, Nm 87545 Timing: Fiscal Year 2001; Project Start 19-APR-1991; Project End 31-MAR-2005 Summary: Mathematical modeling combined with experiment has led to increased understanding of the processes that underlie HIV-1 infection in humans and the development of improved therapies. Nevertheless HIV has not been eradicated from infected individuals and various reservoirs including latently-infected cells, virus trapped on folliculary dendritic cells (FDC), and virus in semen have been identified. This application proposes to continue the development of more realistic models of HIV infection with particular emphasis on events that occur in lymphoid tissue. The applicants propose to develop models that explicitly take into consideration infection in blood and tissue, the role of FDC, and possible incomplete penetrance of drugs into various cell populations and tissues. The primary health-related effects of HIV infection are consequences of CD4+ T cell depletion. Nevertheless, the population dynamics of T cells in vivo are poorly characterized. It is proposed to develop theory and analyze data from in vivo labeling studies that will help characterize the rates of proliferation and death of T cells in uninfected, HIV-infected, and HIV-infected individuals under potent antiretroviral treatment. Infection by hepatitis C virus (HCV) and hepatitis B virus (HBV) continue to cause liver failure and hepatocellular carcinoma in many infected individuals. Antiviral therapy for these agents lags behind developments in HIV. The applicants propose to use the modeling and analysis tools that they have developed for HIV to increase understanding of the in vivo kinetics of HCV and HBV infection and the effects of antiviral therapy. In addition to gaining basic understanding, this approach aims to put information into a practical setting, and the applicants hope to interact with clinical groups in the design and evaluation of new treatment protocols.

Project Title: MODULATION OF OXIDATIVE DAMAGE BY TEA POLYPHENOLS Principal Investigator & Institution: Wang, Jia-Sheng; None; Texas Tech University Health Scis Center Health Sciences Center Lubbock, Tx 79430 Timing: Fiscal Year 2001; Project Start 30-SEP-2001; Project End 31-AUG-2003 Summary: (provided by applicant) The primary objective of this research project is to study the modulating effects of green tea polyphenols on reducing hepatocarcinogeninduced oxidative damages in high-risk human populations. Oxidative damage induced by reactive oxygen species in vivo plays important roles in human hepatocarcinogenesis primarily caused by chronic infection of hepatitis B/C viruses and exposure to dietary aflatoxins. The level of 8-hydroxy-2'- deoxyguanosine, a biomarker for oxidative DNA damage, increases in hepatitis B virus surface antigen positive and aflatoxin-exposed humans and in aflatoxin- treated animals. Dietary antioxidants are important components of cancer modulating agents, which have been proven to effectively target carcinogen biomarkers, including oxidative damages, in high-risk human populations. Among various identified dietary associated antioxidants, green tea and its polyphenols have been shown to be safe and highly effective in inhibition of a variety of carcinogeninduced oxidative damages, mutagenesis, and tumorigenesis in in vitro bioassays and in vivo animal models. The general hypothesis underlying this proposal is that green tea polyphenols have a protective effect against oxidative stress or damage induced by aflatoxin and hepatitis B/C viruses through the mechanisms of modulating aflatoxin metabolism and oxidated DNA damage. The specific aims include: (1) to determine antioxidative role of green tea polyphenols in inhibition of the level of 8-hydroxy-2'deoxyguanosine in urine samples collected from an intervention study of 120 participants who are double positive for hepatitis B virus surface antigen and aflatoxinalbumin adducts, and (2) to determine the modulating effect of green tea polyphenols on excretion of carcinogen detoxifying product, aflatoxin Bl-mercapturic acid in urine samples collected from the study participants. The results of this proposed study will help to understand the mechanisms of antioxidative role of tea polyphenols in modulating human hepatocarcinogenesis caused by hepatitis B/C viruses and aflatoxins.

Project Title: MOLECULAR BIOLOGY OF THE HEPATITIS B TYPE VIRUSES Principal Investigator & Institution: Ganem, Don E.; Professor & Howard Hughes Investigator; Microbiology and Immunology; University of California San Francisco 500 Parnassus Ave San Francisco, Ca 94122 Timing: Fiscal Year 2001; Project Start 01-SEP-1982; Project End 31-MAR-2003 Summary: Hepatitis B virus (HBV) and hepatitis D virus (HDV) are important causes of acute and chronic hepatitis in humans. Although much is known about the replication of these viruses, less is known about how replication causes disease. Evidence suggests that, in HBV infection, host immune responses trigger liver injury and affect viral replication. This application proposes studies to further examine the nature of these immune responses and to determine if similar responses can occur in HDV infection; the ability of such responses to affect HDV RNA replication will also be examined. In addition, detailed studies of the mechanisms of HDV RNA replication will be conducted, with emphasis on the involvement of host factors in this important reaction.

Principal Investigator & Institution: London, W. Thomas.; Senior Member; Fox Chase Cancer Center Philadelphia, Pa 19111 Timing: Fiscal Year 2001; Project Start 15-DEC-1988; Project End 31-JAN-2004 Summary: Worldwide, hepatocellular carcinoma (HCC) is the third most common cause of cancer deaths in men and the seventh most common in women. About 80% of the cases of HCC are associated with chronic infection with hepatitis B virus (HBV), but chronic carriers of HBV differ widely in their risk of HCC. Prospective studies of 60,984 men in Haimen City, China and 19,469 men in Senegal, west Africa, undertaken during the current funding period, revealed a 14-fold greater death rate from HCC among the Haimen than the Senegalese cohort. The age-adjusted prevalence of chronic HBV infection is about 20% in both cohorts. Exposure to aflatoxin, a postulated major risk factor for HCC, does not distinguish these two populations; Senegalese men were universally and heavily exposed. The prevalence of viremia (HBV DNA in serum) among HBV carriers throughout adult life is much higher among the Chinese than the Senegalese population and may be related to the mechanism by which chronic HV infection induces HCC. The mechanism, however, is still unknown. Therefore, the purpose of this program project is to understand the inter- relationships of HBV and other viral infections, environmental factors, genetic events and gene-environment interactions to the etiology and pathogenesis of (HCC). The Specific Aims are: 1) To compare variations in viral, genetic, and environmental factors associated with development of HCC to variations in risk of HCC observed in 3 cohort studies in China, Senegal, and Philadelphia. 2) To understand the cellular and molecular changes in the liver induced by chronic molecular genetic changes in tumor cells associated with HCC. 4) To identify genetic factors and gene- environment interactions associated with susceptibility to HCC. A multi- disciplinary team of scientists from China, Senegal, and the Fox Chase Cancer Center will address these Aims in three Projects (Molecular Epidemiology of HBV and HCC in Three Populations, Genetic Epidemiology of HCC, and Pathobiology of Acute and Chronic Hepadnavirus Infections) supported by three Core facilities (Population Resources, Laboratory Services, Administration). The ultimate goal of this research is to develop strategies for reducing the global burden of HCC. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen •

Principal Investigator & Institution: Kensler, Thomas W.; Professor; Environmental Health Sciences; Johns Hopkins University 3400 N Charles St Baltimore, Md 21218 Timing: Fiscal Year 2001; Project Start 01-SEP-1985; Project End 31-JAN-2004 Summary: Cancer prevention involving reduction or elimination of human exposure to environmental carcinogens may not always be possible. Inhibition of the development of cancer by the administration of anticarcinogenic age may offer a practical alternative for reducing human cancer burden. However, the successful utilization of chemopreventive interventions will require solid mechanistic understanding of the action(s) of these agents. The proposed studies will continue to investigate the modes of protection afforded by oltipraz and other 1,2-dithiole-3-thiones on aflatoxin (AFB1) hepatocarcinogenesis in the rat. Oltipraz is an effective and potent inhibitor of experimental carcinogenesis induced by many agents in many tissues. Oltipraz is

currently being evaluated in Phase I and II clinical chemoprevention trials. This project will continue the development and evaluation of dithiolethiones more active than oltipraz on a) inhibition of AFB1-induced tumorigenesis in rats; b) altered AFB- DNA adduct formation; and c) induction of carcinogen detoxication ("phase 2") enzymes. Using a large series of analogs synthesized previously, the structure-activity relationships for inhibition of cytochrome P450 activation of AFB1 metabolism will also be determined. Using molecular genetic approaches, the identification and characterization of genes induced by dithiolethiones in rat liver will be continued together with elucidation of the role(s) of these gene products in protection against aflatoxin toxicity and carcinogenicity. Several novel inducible genes recently identified may protect against inflammation and oxidative stress. Finally, the chemopreventive actions and efficacy of oltipraz will be evaluated in a unique experimental model, the tree shrew, in which infection with human hepatitis B virus and exposure to AFB1 synergistically enhance the incidence of liver cancer, as occurs in humans. Collectively, these multifaceted, integrated studies will more fully define the chemical, molecular, biochemical and biological mechanisms of action of this versatile class of chemoprotective agents. The long-term goal of this project is to facilitate the most efficient and effective use dithiolethiones as protective agents in human populations exposed to environmental toxicants.

Principal Investigator & Institution: Neuwald, Paul D.; Acrometrix Corporation 1440 4Th St Berkeley, Ca 94710 Timing: Fiscal Year 2001; Project Start 15-JUN-2001; Project End 30-NOV-2001 Summary: (Applicant's Abstract): Nucleic acid testing procedures for genotyping of viral pathogens provide results that are utilized in the diagnosis and treatment of diseases such as hepatitis and AIDS. Medical products that directly measure these genetic variants currently utilize internal standards developed by the test manufacturers. The need exists for third party genotyping standards that offer common units of measure and provide testing laboratories with independent methods for ensuring accuracy, reproducibility and consistency in their test procedures. During Phase I, clinical specimens representing the major genotypes of hepatitis B virus (HBV genotypes A - F) and hepatitis C virus (HCV genotypes 1 - 6) will be obtained for calibration against World Health Organization International Standards for these virus nucleic acids, and evaluated for use as potential genotype standards using a variety of commercially available genotyping systems. During Phase II of this project, these materials will be further developed into viral and molecular (cloned DNA or RNA transcripts) standards for HBV and HCV genotyping. The HBV product will be further expanded to include standards for antiviral drug resistance mutations in this virus. All viral and molecular standards will be made commercially available during Phase Ill. PROPOSED COMMERCIAL APPLICATION: This research will lead to the development and commercialization of viral and molecular standards for HBV and HCV genotyping, including HBV drug resistance mutations. Such standardization, currently being implemented for viral load testing, is sorely needed for genotype testing, will facilitate the acceptance of common units of measure for assessing viral genotypes, and will help ensure that genotyping results obtained from multiple laboratories using a variety of test systems throughout the world are accurate,

Project Title: MUTATIONS IN HUMAN P53 SEQUENCES OF A P53 KNOCK-IN MOUSE Principal Investigator & Institution: Hollstein, Monica C.; German Cancer Research Center Im Neuenheimer Feld 280 Heidelberg, Timing: Fiscal Year 2001; Project Start 15-JUL-1999; Project End 30-JUN-2002 Summary: The long-term objectives of this proposal are to test a humanized genetargeted p53 tumor suppressor gene knock-in mouse as an experimental tool for molecular epidemiology, chemoprevention, and cancer therapy studies. This new model is designed to reflect and predict more faithfully than the currently used mouse models, human in vivo mutagenesis, carcinogenesis and responses to therapeutic drugs that target p53 protein. The specific aims are 1) to induce tumor mutations in human p53 sequences of knock-in mice exposed to human carcinogens, and compare them to human tumor p53 mutation spectra; 2) to test whether a p53 hotspot mutation common in aflatoxin-associated human liver cancers occurs in liver tumors of aflatoxin B1exposed, hepatitis B virus-transgenic/human p53 knock-in mice; 3) to generate mouse strains that harbor a mutant human p53 sequence identical to one of the inherited p53 mutations of cancer-prone Li-Fraumeni families. These p53 mutant mouse strains provide a new animal model, with an allelic configuration that parallels the human situation, for testing chemotherapeutic agents and chemopreventive dietary factors; 4) to replace mouse regulatory sequences with human elements, and determine how this alters p53 expression; these data may be useful in developing next generation p53 knock-in mouse strains. The research plan involves: 1) Construction of gene-targeting plasmids; 2) Generation of gene-targeted mouse strains in which exons 5-9 of the endogenous mouse p53 gene have been replaced by the corresponding human segment; 3) Treatment of p53 knock-in strains with human carcinogens; 4) Analysis of tumors and normal tissues for p53 mutations, and alterations in p53 message and protein. The methods to be used are: (a) Standard cloning procedures for plasmid construction; (b) gene-targeted technology with ES cells, and knock-in/knock-out strategies; (c) mouse breeding and treatment with carcinogens; (d) DNA sequencing, PCR and RT-PCR amplification; (e) immunohistochemistry; (f) mutation analysis by DGGE and allelespecific PCR. New pharmaceuticals designed to regenerate tumor suppressor functions of a mutated p53 in humans can be tested in vivo in these humanized" mice because they have a core domain identical to the human p53 protein rather than the mouse p53 protein.

Project Title: NEW HEPATITIS B SMALL MOLECULE INHIBITORS Principal Investigator & Institution: Mehta, Anand S.; Associate Professor; Synergy Pharmaceuticals, Inc. 2 Executive Dr, Ste 450 Somerset, Nj 08873 Timing: Fiscal Year 2001; Project Start 01-SEP-2001; Project End 31-AUG-2003 Summary: (provided by applicant): The over-all goal of this "fast track" proposal is to develop a new class of orally available compounds for the treatment of chronic human hepatitis B virus (HBV) infection through a "proof of principle" Phase I/IIa Human clinical trial. With our colleagues, we have shown that alkylated imino sugars, called "alkovirs," are novel and effective in preventing HBV replication in tissue culture

systems under conditions where there is no detectable cyto-toxicity. The alkovirs are previously undescribed synthetic (hence completely characterized) small molecules. Unlike the glucosidase inhibitors, (another class of imino sugars that we have been studying) alkovirs do not inhibit glucosidases, making them distinct and conferring certain advantages. Moreover, although alkovirs inhibit HBV replication, they do not target the viral polymerase, as do most nucleoside analogues. Thus, alkovirs should be effective against lamivudine "resistant" HBV mutants. The objectives of this "fast track" proposal are intended to be straightforward and defined by clear milestones: In phase I, the Alkovir(s) with the most potent anti-HBV activity against wild type virus and lamivudine resistant virus will be selected and tested for in vivo toxicity and pharmacokinetics in a rat model. In Phase II, the efficacy and toxicity of the candidate Alkovir(s) selected in Phase I will be evaluated in the woodchuck model of chronic hepatitis virus infection both as monotherapy and in combination with 3TC-lamivudine. Other work, to be performed in parallel with this study, will explore the precise mechanism of action of alkovirs and possibility that (a) they are effective against other viruses and (b) are a class of compounds to which mutant viruses do not frequently emerge. Accomplishment of these Aims will permit the introduction of alkovirs for human clinical trials. Given the need to find complements to nucleoside analogues, the introduction of new anti-hepatitis B virus agents as described here is extremely important.

Project Title: NONINJECTED HEROIN USE, HIV AND TRANSITIONS TO INJECTION Principal Investigator & Institution: Ouellet, Lawrence J.; Epidemiology and Biostatistics; University of Illinois at Chicago 1737 West Polk Street Chicago, Il 60612 Timing: Fiscal Year 2001; Project Start 20-SEP-2000; Project End 31-AUG-2005 Summary: (adapted from the applicant's abstract): Growing cohorts of young noninjecting heroin users (NIHU) are making choices regarding drug injection that promise to shape the AIDS epidemic in Chicago and other U.S. cites for years to come. Despite the potential impact of NIHU on future AIDS trends, published research on this group in the U.S. is scarce and little is known about their transitions into injection. To help fill this void, we propose a five-year, longitudinal study of NIHU in Chicago that has three major aims: (1) measure the incidence of transitions by NIHU into drug injection and identify factors predicting this event; (2) measure the incidence and prevalence of HIV, hepatitis C, and hepatitis B infections among NIHU and identify factors associated with infection, and (3) explore the link between heroin use and risky sexual practices. The proposed study is grounded conceptually in social epidemiology, which models disease patterns as the product of interactions between an agent, host, and environment. The study will use a multi-method research design that combines a prospective epidemiologic survey, biologic testing, and qualitative interviewing. This design will enable causal analyses of the impact of independent variables on the outcomes of interest. The sample will consist of 1000 NIHU 16-30 years old recruited through respondent-driven sampling from areas across Chicago and its suburbs. Variable categories thought likely to predict major outcomes of interest are changing conditions in the properties and availability of heroin (agent/drug), individual characteristics (host/set), and the social settings within which drug use occurs (environment/setting). The goal of this study is to better understand current drug use patterns and HIV risk practices, particularly transitions to injection, among NIHU. We anticipate our findings being used to develop intervention strategies aimed at preventing drug injection and

other HIV related behaviors among NIHU. To increase the scope and generalizability of findings, elements of the proposed study, including the survey questionnaire, have been designed for comparison with an ongoing NIDA-funded, prospective study of NIHU in New York City.

Project Title: NONINJECTING HEROIN USERS, NEW INJECTORS AND HIV RISK Principal Investigator & Institution: Neaigus, Alan; National Development & Res Institutes Research Institutes, Inc. New York, Ny 10010 Timing: Fiscal Year 2001; Project Start 01-JUL-1995; Project End 31-MAR-2003 Summary: Non-injecting heroin use is widespread in New York City and in many other cities. Non-injecting heroin users (NIUs) are at high risk of becoming injecting drug users (IDUs). Increases in the number of new IDUs can lead to many new infections with HIV, hepatitis B (HBV) and hepatitis C (HCV). This study will continue the "HIV Risk and Transitions from Non- Injecting Heroin Use" (NIU) cohort study of approximately 600 NIUs. It will follow the NIU cohort and a cohort of new IDUs, to determine: (1) the incidence and time-trends in transitions to injecting; (2) behavioral and network risks for transitions to injecting and other drug use outcomes; (3) separately, for new IDUs and for NIUs, the incidence and time-trends in HIV, HBV and HCV seroconversions; (4) among NIUs, sexual and other non- injecting risk behaviors and networks predicting HIV, HBV and HCV seroconversion; (5) among new IDUs, drug injecting and sexual risk behaviors and risk networks predicting HIV, HBV and HCV seroconversion; (6) time-trends in the prevalence of drug and sexual risk behaviors and risk networks, and factors predicting these trends; and (7) the impact of changes in the quality and availability of heroin, and in other community factors, on modes of drug administration and other drug and sexual risk behaviors and risk networks. The sample will include: NIUs from the parent study; new IDUs recruited from a supplemental study of network risks for HIV, HBV and HCV infection; and NIUs and new IDUs recruited during the study continuation. Participants will be interviewed and tested for HIV, HBV, and HCV. Ethnography will be used to study the impact of drug markets. Analyses of risk factors for transitions to injecting and seroconversions will explore the "network facilitation" hypothesis by examining the extent to which network characteristics, in interaction with risk behaviors, facilitate transitions to injecting or the cessation of heroin use and other drug use outcomes, and seroconversions. This approach will advance our knowledge of the interaction between network processes and risk behaviors, and can be used to develop interventions to change both risk behaviors and risk networks, and to prevent transitions to injecting and the risk of HIV, HBV and HCV infection.

73

infectious entity of potentially large medical significance. Occult hepatitis B has been associated with advanced liver fibrosis, coinfection with hepatitis C, IFN alpha resistance in treatment of hepatitis C, and hepatocellular carcinoma. The overall aim of Dr. Torbenson's proposal is to assess the prevalence and clinical significance of occult hepatitis B in high risk patient population of injection drug users. This study utilizes the unique resources of a pre-existing longitudinal collection of sera and liver tissue from the mentor's ongoing research, allowing assessment of the prevalence of occult hepatitis B over time and estimation of the rate of fibrosis progression in these individuals. The first aim examines the overall prevalence of occult hepatitis B and investigates the impact of Human Immunodeficiency Virus status on the presence of occult hepatitis B. The second aim assess the clinical significance of occult hepatitis B by correlating the presence of occult hepatitis B with the amount of inflammation and fibrosis on liver biopsy. The rate of fibrosis progression will be investigated by comparing the amount of fibrosis on initial liver biopsy to that on follow-up biopsies. In addition, aim 2 will examine the role of occult hepatitis B in HIV progression. The third aim focuses on potential mechanisms of occult hepatitis B and seeks to identify relevant hepatitis B gene mutations. As a final element of this aim, carefully selected (based on known involvement in typical hepatitis B viral infection) signaling pathways will be investigated by analysis of mRNA and protein expression to investigate host-viral interactions.

Project Title: PATHOGENESIS OF GROUND GLASS CELLS IN HEPATITIS B Principal Investigator & Institution: Yen, T.S. Benedict.; Professor; Northern California Institute Res & Educ San Francisco, Ca 941211545 Timing: Fiscal Year 2001; Project Start 05-MAR-1992; Project End 31-MAR-2006 Summary: (Adapted from the Investigator's abstract): Hepatitis B virus (HBV) causes chronic hepatitis, cirrhosis, and hepatocellular carcinoma (HCC), and is especially common among minorities such as African Americans and Asian Americans. The mechanism by which HBV causes HCC is unclear, but it is likely that HCC results from both specific viral factors and non-specific mutagenesis due to constant cell turnover. One candidate viral factor is the large surface protein, since expression of this protein in transgenic mice results in HCC. We have recently shown that large surface protein can activate cellular genes at the transcriptional level, apparently by forming non-secretable particles in the endoplasmic reticulum (ER) and activating ER stress. Further preliminary data indicate that large surface protein causes cell death, probably by apoptosis. Since hepatocytes containing large surface protein particles within the ER ("ground glass cells") are seen in the livers of people with chronic hepatitis B, our results point to a specific mechanism whereby HBV may cause HCC. However, the reason for ground glass cell formation in infected livers is still unclear. For the next cycle of this project, we propose to study events both up-stream and down-stream of the formation of ground glass cells. First, we wish to validate our hypothesis that mutations in the viral genome can lead to ground glass cells, and determine if two common naturally occurring viral mutants can cause ground glass cells and HCC in transgenic mice. Second, we will clone out HBV genomes from human ground glass cells, and look for additional mutations that may be responsible for ground glass cell formation. Third, we will determine how large surface protein causes cell death, and whether it is by apoptosis. We will also determine if there is increased apoptosis of ground glass cells in transgenic mice, and look for activation of apoptotic pathways in human livers with

Project Title: PATHOGENESIS OF LIVER DISEASE IN HEPATITIS Principal Investigator & Institution: Chisari, Francis V.; Professor & Head; Scripps Research Institute Tpc7 La Jolla, Ca 92037 Timing: Fiscal Year 2001; Project Start 01-JUL-1983; Project End 30-JUN-2003 Summary: (adapted from the investigator's abstract) During the current funding interval Dr. Chisari established the technology required to detect, quantitative and characterize the cytotoxic T lymphocyte (CTL) response to the hepatitis B and C viruses. Using this technology he defined the salient features of the host-virus relationship during the acute and chronic phases of these infections and, in the process, established the rationale and identified the immunological targets for antigen-specific immunotherapy of chronic hepatitis. Despite these advances, the very early aspects of the host-virus relationship during HBV and HCV infection are completely unexplored because, for practical and ethical reasons, it is extremely difficult to access the incubation period in infected patients. Nonetheless, these early host-virus interactions are likely to be key determinants of the outcome of these infections. In the next funding interval, he will examine the virological, immunological and pathological features of the host-virus relationship from the moment of HBV and HCV infection until their final outcome in experimentally infected chimpanzees. As in humans, almost all adult onset HBV infections in chimps are self limited, while only half of chimp HCV infections are self limited and the rest become persistent. Thus, he will compare and contrast the early intrahepatic T cell responses to HBV and HCV to test the hypothesis that the outcome of these infections is determined by the kinetics, vigor, diversity and cytokine profiles of the intrahepatic T cell response and the ability of the virus to spread and to evade immune recognition during the early incubation period of each infection. Thanks to the close relatedness of chimps and humans, most of the reagents and techniques required to define the intrahepatic antigen specific T cell response to these viruses are already available. The information forthcoming from these studies will, for the first time, define the virological and immunological features of early HBV and HCV infection and determine the extent to which they influence viral clearance and disease pathogenesis in these diseases.

Project Title: PSYCHOLOGICAL STRESS AND IMMUNE RESPONSE TO VACCINATION Principal Investigator & Institution: Marsland, Anna L.; Pathology; University of Pittsburgh at Pittsburgh 350 Thackeray Hall Pittsburgh, Pa 15260 Timing: Fiscal Year 2003; Project Start 01-SEP-2003; Project End 31-MAY-2008 Summary: (provided by applicant): It is widely proposed that the influence of stress on immune function is the primary biological pathway linking stress to increased infectious disease susceptibility. However, the literature is missing empirical evidence for this pathway, in part because of a failure to focus on immune measures that are relevant for the development of host resistance. The broad objective of the proposed study is to identify pathways linking psychological stress to in vivo immune processes that are clinically relevant for the development and maintenance of resistance to infectious disease. For this purpose, a hepatitis B vaccination model is employed. This model

permits the systematic exploration of behavioral and biological pathways linking stress to ability to mount and maintain primary and secondary antibody responses following exposure to a novel antigen. It also allows the exploration of the role that individual differences in the magnitude of biological responses to stress play in vulnerability to stress-immune relationship. In this regard, it has been demonstrated that individuals vary consistently in the magnitude of their cortisol and immune responses to acute stress, conceivably rending them more or less able to mount an antibody response to vaccination. One hundred and eight-two healthy males and females aged 40-60 years will be recruited to participate in the proposed longitudinal research, which includes a laboratory based physiological reactivity phase, a prospective surveillance phase and a follow-up period. In the reactivity phase, participant's immune and cortisol responses to an acute laboratory stressor will be measured to determine individual differences in the magnitude of immunologic reactivity to stress. During this phase, participants will also complete self-report measures of recent life stress and trait negative affect. In the surveillance phase, participants will be administered the three does of hepatitis B vaccine by standard protocol. They will also complete daily stress diaries for the seven days surrounding each dose of vaccine to assess levels of acute stress. Saliva samples for the assessment of cortisol levels will be collected at the time of each vaccination. Antibody responses will be measured at the time of the second and third does of vaccine and, during the follow-up period, 6 and 12 months following completion of the vaccination series.

Project Title: RECOMBINANT ATTENUATED SALMONELLA VACCINES FOR HUMANS Principal Investigator & Institution: Curtiss, Roy Iii.; Professor; Biology; Washington University Lindell and Skinker Blvd St. Louis, Mo 63130 Timing: Fiscal Year 2003; Project Start 01-JUL-2003; Project End 31-DEC-2007 Summary: (provided by applicant): Of the 18.9 million annual deaths (1997) due to infectious diseases, about 7.5 million, in addition to significant morbidity, are the result of infections by Salmonella typhi, S. paratyphi A, hepatitis B virus (HBV), Plasmodium falciparum, Streptococcus pneumoniae and Mycobacterium tuberculosis. In the belief that improving health, nutrition and economic well-being (the later dependant on the first two) provides the best means to enhance the quality of life globally and thus reduces conditions that result in warlike and terrorist behavior, we propose a vaccine development program based on our recent technical developments in using recombinant attenuated Salmonella vaccines. Our objectives include: (a) to design, construct and evaluate an attenuated derivative of S. paratyphi A that will serve as an antigen delivery vector by exhibiting regulated delayed lysis within effector lymphoid tissues in the immunized individual to release hepatitis B virus (HBV) core particles encoding (i) HBV pre $1, pre $2 and T-cell epitopes as a preventative/therapeutic vaccine against HBV and (ii) P. falciparum circumsporozoite epitopes as a vaccine against malaria; (b) to construct and evaluate the contribution of strain background and the RpoS* phenotype on immunogenicity of a recombinant antigen expressed by attenuated S. typhi vaccine strains; and (c) to design, construct and evaluate recombinant attenuated S. typhi vaccines to express and deliver protective antigens specified by genetic information from (i) S. pneumoniae to prevent pneumococcal disease caused by strains with diverse capsular serotypes and (ii) M. tuberculosis as a preventative/therapeutic vaccine. The S. paratyphi A and S. typhi recombinant vaccines should also provide immunity to infection by S. paratyphi A and S. typhL We will also

Project Title: RECURRENT HEPATITIS B AFTER LIVER TRANSPLANTATION Principal Investigator & Institution: Lok, Anna S.; Professor; Internal Medicine; University of Michigan at Ann Arbor 3003 South State, Room 1040 Ann Arbor, Mi 481091274 Timing: Fiscal Year 2001; Project Start 01-JUN-2001; Project End 31-MAY-2008 Summary: Hepatitis B accounts for approximately 5000 deaths/yr in the United States. Early results with orthotopic liver transplantation (OLT) for hepatitis B were poor with recurrence rates of >80% and 2-year mortality rates of 50%. Recent studies found that continuous high dose IV hepatitis B immune globulin (HBIG) can decrease the rate of reinfection to <20%. However, high dose HBIG is very expensive ($30,000-$50,000/yr) and the efficacy is low in patients with replicative infection pre-OLT. Pilot studies showed that lamivudine (LAM, an oral nucleoside analog which costs $1,200-$1,500 per yr) can decrease the rate of recurrent hepatitis B to <30% during the first post-OLT year but the long-term efficacy is limited by drug resistant mutants. Three pilot studies reported that combination therapy of HBIG and LAM is more effective than either agent alone with recurrence rates <5%, but it is not clear how long HBIG needs to be administered. Given the high costs and the inconvenience of life-long HBIG therapy, there is a need for a prospective, randomized controlled trial to determine if prophylaxis with LAM and short-term HBIG is as effective as LAM and long-term HBIG in the prevention of recurrent hepatitis B post-OLT. The use of antiviral agents with potential activity against LAM resistant HBV mutants, such as adefovir dipivoxil, also needs to be evaluated. The specific aims of our study are: (1) To compare the safety, efficacy and cost-effectiveness of combination therapy with LAM and a 6-month course of HBIG with LAM and a 3-yr course of HBIG in the prevention of recurrent hepatitis B postOLT. (2) To identify the epidemiological, clinical and virological factors that are associated with recurrent hepatitis B post-OLT. (3) To determine the safety and efficacy of adefovir dipivoxil in the suppression of HBV replication in patients who have developed LAM resistant HBV mutants and to compare the rate of recurrent hepatitis B post-OLT in patients with and without LAM resistant mutants prior to transplant. This is a prospective, randomized, multi-center clinical trial involving 20 liver transplant centers in N. America, to be conducted under an investigator IND 59,167. 290 patients with hepatitis B who are listed for OLT as UNOS status 1 or 2 will be enrolled. Open label LAM will be administered to decrease virus load pre-OLT. Patients will be randomized after OLT to Group I: LAM and 3 yr-course of HBIG or Group II: LAM and 6-month course of HBIG. Patients who develop LAM resistant mutants pre- or postOLT will additionally receive adefovir dipivoxil. The primary end-point of this trial is the rate of recurrent hepatitis B during the first 3 yr post-OLT. This trial will provide definitive answers whether combination therapy with LAM and a 6-mon course of HBIG is as efficacious and more cost-effective than LAM and a 3-yr course of HBIG in the prevention of recurrent hepatitis B post-OLT. In addition, crucial data will be generated on the efficacy of pre-OLT LAM in virus clearance, incidence and outcome of silent allograft infection, clinical outcome of patients with LAM resistant HBV mutants, and management of patients with LAM resistant mutants.

Project Title: REGULATION OF HBV REPLICATION BY OTHER HUMAN PATHOGENS Principal Investigator & Institution: Guidotti, Luca G.; Associate Professor; Scripps Research Institute Tpc7 La Jolla, Ca 92037 Timing: Fiscal Year 2001; Project Start 01-JAN-1997; Project End 31-DEC-2001 Summary: The hepatitis B virus (HBV) causes acute and chronic necroinflammatory liver disease and hepatocellular carcinoma. Over 300 million people worldwide are persistently infected by HBV, representing an enormous reservoir for horizontal and vertical spread of this virus to others. The long term objective of this application is to understand the host- virus interactions responsible for HBV persistence with the ultimate hope that this knowledge will lead to the development of new therapeutic strategies to terminate persistent infection and its attendant costs and complications. Using transgenic mice that replicate HBV at high levels in the liver as recipients of HBVspecific CTL and hepatotropic viruses such as lymphocytic choriomeningitis virus (LCMV), we have shown that HBV replication is abolished by these agents, noncytopathically, as a result of the intrahepatic induction of interferon alpha, interferon gamma and tumor necrosis factor alpha (type 1 cytokines). We now propose to examine the antiviral regulatory networks that are activated in the LCMV-infected liver in order to identify the ligand-receptor interactions that trigger the hepatocyte to suppress HBV gene expression and replication in vivo. Since the intrahepatic macrophage (Kupffer cell) is an important and well placed source of potentially active antiviral mediators in this system, we will determine whether physiological and pharmacological activation of the Kupffer cell is sufficient to clear HBV from the hepatocyte in vivo. if successful, these studies would establish the concept that inducible cellular crosstalk can control viral infection, perhaps leading to the development of an entirely new area of viral immunotherapeutics. Finally, in view of our findings it is possible that HBV persistence might be favored by inflammatory responses dominated by type 2 cytokines (eg interleukins 4, 5 and 10). To explore this hypothesis, we will determine whether intrahepatic type 2 inflammatory responses initiated by schistosomal and leishmanial infection are able to clear HBV from the liver of these animals. The results of these experiments will not only provide insight into the basic immunological processes that may determine HBV persistence, but additionally they may also shed light on the basis for the more aggressive liver disease that occurs in millions of patients with chronic HBV infection who are superinfected by these parasites in developing countries throughout the world.

Project Title: REGULATION OF TBP BY HBV X ON TRANSFORMATION Principal Investigator & Institution: Johnson, Deborah L.; Associate Professor; Molecular Pharm & Toxicology; University of Southern California 2250 Alcazar Street, Csc-219 Los Angeles, Ca 90033 Timing: Fiscal Year 2001; Project Start 10-MAY-1997; Project End 31-JAN-2005 Summary: (Adapted from the investigator's abstract) The Hepatitis B virus (HBV) is a common infectious agent. The HBV protein product, X, has shown to be essential for viral replication, and it is strongly implicated in the development of hepatocellular carcinoma in chronically infected HBV patients, yet its role in these events is not wellunderstood. Our previous work has comprehensively defined the mechanism for how X transactivated RNA polymerase I and III promoters. We made the interesting discovery that X induces the promoters by activating the Ras signal transduction pathway which

78

Hepatitis B

then increases the cellular levels of the central transcription factor, TATA-binding protein (TBP). Increases in cellular TBP augment RNA pol I and III transcription and differentially regulate RNA pol II promoters. Our research plan will clearly delineate how X, an oncogenic Ras, increase cellular TBP levels. The proposed aims will rigorously investigate each event in the TBP gene expression process that gives rise to the final TBP product. By examining the individual contribution of each process, and how it differs when either X or oncegenic Ras is expressed in cells, we will obtain a good quantitative picture of how this X- and oncogenic Ras-mediated increase in TBP occurs. We have promising new data indicating that a key step leading to the increase in TBP is due to an increase in TBP promoter activity. Therefore, a major focus of the proposed studies will be to examine how the TBP promoter is regulated by X and by oncogenic Ras. We will comprehensively define the X-mediated signaling events downstream of Ras to the promoter that modulate TBP promoter activity. Since X has been shown to transform cells, and Ras is strongly oncegenic, we will also determine how alterations in the cellular levels of TBP can affect the transformation potential of cells. Focus formation, growth in soft agar, and mouse tumorigenesis assays will be used to assess whether directly overexpressing TBP can enhance transforming activity or whether down-regulating its production in cells can prevent Ras-induced transformation. Using mutant TBP proteins that are specifically defective in RNA pol II or pol III transcription, we will define specific changes in cellular gene expression occurring in TBPoverexpressing cells that contribute to transformation. These studies promise to make unique and important new contributions to our understanding of the function of the HBV X protein and oncegenic Ras, the regulation of TBP, and their consequences on cellular gene activity that leads to cellular transformation.

Project Title: REPLICATION AND PATHOGENESIS OF HEPATITIS B VIRUS Principal Investigator & Institution: Ou, Jing-Hsiung J.; Professor; Molecular Microbiol and Immun; University of Southern California 2250 Alcazar Street, Csc-219 Los Angeles, Ca 90033 Timing: Fiscal Year 2001; Project Start 10-APR-1998; Project End 31-JAN-2002 Summary: Dr. Ou proposes to study three aspects of the HBV pathogenesis and its replication cycle: core protein phosphorylation, C gene transcription controls, and the role of the X gene in replication. Aim 1 will evaluate the model that core protein phosphorylation blocks virus assembly. Virions will be analyzed for phosphorylation; virus infection will be reconstituted with core proteins mutated to block phosphorylation at specific residues. Viral regulation, packaging efficiency, and virion production will be analyzed. Aim 2 deals with transcriptional regulation of the core gene, which actually encodes both precore and core proteins by initiating from two different transcription start sites. The study will focus on a critical regulatory site that binds COUP, HNF4, PPAR-RXR, and when mutated, HNF1. Preliminary studies have also characterized an upstream negative regulatory element (NRE) that binds RFX1/MDBP1 and MIBP1. The NRE will be further analyzed in Aim 3. Finally, Aim 4 will evaluate whether the X protein activates cell cycle-dependent genes to support HBV regulation. For these studies, a transgenic mouse will be constructed to incorporate a functional HBV genome, but with a defective X gene. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen

Project Title: ROLE OF GLYCINE DECARBOXYLASE IN HEPADNAVIRAL INFECTION Principal Investigator & Institution: Li, Jisu; Assistant Professor; Rhode Island Hospital (Providence, Ri) Providence, Ri 02903 Timing: Fiscal Year 2002; Project Start 01-APR-2002; Project End 31-MAR-2004 Summary: Hepatitis B virus is a major cause of liver cirrhosis and hepatocellular carcinoma (HCC). A better understanding of the viral life cycle may provide targets for the intervention of HBV infection, thus reducing the risk of HBV-related HCC. However, the early stages of the viral life cycle and viral-host interactions that contribute to viral infection and pathogenicity are poorly understood. This 421 exploratory proposal focuses on studies on a hepadna virus interacting protein, p120/glycine decarboxylase. We have previous found that p120 is a binding partner of an avian hepatitis B virus envelope protein. It is expressed only in the virus infectable tissues and its expression level is directly correlated with the cellular susceptibility to virus infection. It is expressed only in the virus infectable tissues and its expression level is directly correlated with the cellular susceptibility to virus infection. Moreover, viral mutants with an ablated p120-binding site showed reduced infectivity despite wild-type replication capacity. These findings suggest that p120 is associated with the early stage of the viral life cycle. Therefore, we plan to further establish its role in the viral life cycle by genetic approaches. Specific Aim #1 will determine if inhibition of p120 expression or function in well-differentiated duck hepatocytes will reduce susceptibility to viral infection. Specific Aim #2 will examine whether reconstitution of p120 in dedifferentiated duck hepatocytes will restore productive viral infection. In addition, we will determine if p120 is defective in Muscovy ducks, a duck species resistant to hepadnavirus. We will also explore the possibility to restore viral infection by p120 derived from a susceptible Pekin ducks. These studies will provide further information on virus-cell interactions and may lead to development of novel anti-viral strategies for prevention of HBV induced liver cancer.

Project Title: ROLE OF HBX PROTEIN IN HBV REPLICATION Principal Investigator & Institution: Schneider, Robert J.; Professor; Biochemistry; New York University School of Medicine 550 1St Ave New York, Ny 10016 Timing: Fiscal Year 2001; Project Start 01-APR-1992; Project End 31-MAR-2006 Summary: (provided by applicant): The long term objectives of this proposal are to understand the roles of the hepatitis B virus (HBV) HBx gene in viral infection. Please note that the title of this grant has been changed from "Transcription and Transformation by Hepatitis B Virus HBx Protein," to" Role of HBx protein in HBV replication" to reflect the progression of our studies on HBx. AIM 1: Molecular mechanism for human hepatitis B virus (HBV) HBx protein action. HBx activates cytoplasmic signal transduction pathways. HBx activation of the Pyk2-Src tyrosine kinase signalling pathway represents an important activity for viral replication in hepatocytic cell lines. Studies are outlined to understand the molecular mechanism for HBx activation of Pyk2-Src signal transduction, since it is tightly linked to HBx stimulation of viral replication. In addition, HBx appears to possess nuclear functions that may stimulate viral transcription. Studies will also investigate the mechanism by which HBx functions in viral transcription, including a possible role in the nucleus, and its impact on viral replication. AIM 2: Role of HBx protein in HBVreplication. Studies are proposed to determine the molecular basis for HBx activation of HBV reverse

Hepatitis B

transcription and DNA replication. Model systems have been developed for delivery of hepadnavirus genomes to differentiated hepatocytic cell lines and rodent primary hepatocytes in culture, that permit viral replication in an HBx-dependent manner. Studies will investigate the role of HBx in viral replication in a biologically relevant system, focusing on HBx induction of HBV core protein phosphorylation, control of the cell cycle, and induction of nucleotide metabolism. HBx-dependent HBV replication will also be studied in primary hepatocytes prepared from mice that are deficient in genes that impact on HBV replication, including knockouts of Src and Pyk2 kinases, to better understand their importance for viral replication.

Project Title: SELF CLEAVING RNA AND TRANS ACTING RIBOZYMES Principal Investigator & Institution: Been, Michael D.; Professor; Biochemistry; Duke University Durham, Nc 27706 Timing: Fiscal Year 2001; Project Start 30-SEP-1992; Project End 31-AUG-2002 Summary: The objective of the proposed research is to understand the structure, mechanism, and biological role of self-processing RNA (ribozymes). The ribozymes being studied are self-cleaving sequence associated with the genomic and antigenomic RNA of hepatitis delta virus (HDV). HDV is a human pathogen but is always found in association with hepatitis B virus. The combination leads to serious liver damage with a higher fatality rate that in patients infected only with hepatitis B virus. Thus, in populations where hepatitis B is endemic, HDV can be a serious health threat. It can either be co-transmitted with hepatitis B causing the acute form of the disease or it can infect hepatitis B carriers; the later tends to be more serious. The ribozyme activity is thought to be essential to the replication of the RNA genome of this virus. A greater understanding of the ribozyme structure, cleavage mechanism, and role in replication could lead to a method to block viral replication. In addition because the self-cleaving RNA from HDV is the first clear example of a self-cleaving RNA that functions naturally in human cells; an understanding those features that are unique to this RNA may facilitate the design of ribozymes to be used in therapeutics. The specific aims of the proposal are: (1) To generate and refine a three dimensional model for the HDV ribozyme and utilize the models to evaluate biochemical and genetic data on the ribozyme structure and mechanism. Molecular modeling programs, some of which are designed Specifically for RNA, will be used to generate models that are consistent with constraints on the structure established experimentally. Data gathered from physical methods will also be used, and towards this end methods for making large quantities of circular RNA will be used to produce RNA for crystallography. (2) To test and refine the structure through biochemical and genetic approaches. Methods include chemical protection, substitution interference, in vitro mutagenesis and in vitro selection. (3) To define the mechanism and requirements of the reaction. A complete kinetic scheme for the trans-reaction will developed and the stereochemistry of the reaction will defined. (4) To characterize and define cis-acting sequences that interfere with cleavage activity and may limit ribozyme cleavage to the nascent transcript. As part of this study templates for making concatameric RNA sequences that mimic replication of the RNA from a circular template will be developed.

Timing: Fiscal Year 2001; Project Start 01-JAN-1999; Project End 31-MAR-2002 Summary: This study is in response to the program announcement, Health Risk Reduction: Community-Based Strategies, and is an essential step in developing culturally relevant interventions to promote positive sexual health practices and outcomes among homeless adolescents. The specific aims are to 1) describe the sexual health practices, including prevalence and incidence of STD testing, diagnosis, and treatment as well as the prevalence and incidence of immunizations for hepatitis B, of homeless adolescents; 2) examine the relationships among variables in the conceptual model of sexual health practices: sociodemographics, sexual history, culture of homelessness, cognitive perceptual factors, behavioral factors, and individual sexual health practices of homeless adolescents; 3) determine the indirect effects of sociodemographics, sexual history, and culture of homelessness, and the direct effects of cognitive perceptual factors and behavioral factors on individual sexual health practices of homeless adolescents; and 4) explore with homeless adolescents the feasibility of developing culturally relevant interventions to promote positive sexual practices in this population through (a) focus groups that explore their perceptions of factors that are culturally relevant, and (b) comparing characteristics of those subjects who remain connected to the project site for periods of 3, 6, 9, and 12 months and characteristics of those who leave the area during these time intervals. A convenience sample of 460 homeless youth will be surveyed to describe their sexual health practices and to examine relationships among theoretical variables through structural equation modeling. A subsample of 40 homeless youth will participate in focus groups to provide their perspectives on community-based interventions to reduce the risk of sexually transmitted diseases (STDs) that would be culturally relevant and feasible for them. The expected outcomes of the study are the refinement of a theoretical model of sexual health practices that will provide a framework for interventions to reduce the prevalence and incidence of STDs in vulnerable homeless adolescents.

Dr. Cohan has just completed a two-year fellowship in Reproductive Infectious Disease and her Masters in Public Health. She proposes to build on her research skills by learning ethnographic techniques and advanced biostatistical methods, with the ultimate goal of becoming an independent clinical researcher. Dr. Cohan proposes to conduct a multi-level study to identify individual-level psychological factors and population-level network characteristics associated with risk of prevalent HIV-1, sexually transmitted infections (STIs), and hepatitis B (HBV) and C (HCV) among female sex workers in San Francisco. The study combines qualitative and quantitive methods, including ethnography, a cross-sectional survey using venue-based probability sampling, and social network analysis, to describe the sociopolitical, environmental, and psychological forces that underlie sexual and drug-using behavior among sex workers. She proposes three specific aims: (1) to characterize sexual and drug-using behavior and prevalence of HIV, STIs, HBV, and HCV, and to examine

82

Hepatitis B

psychological risk factors associated with these infections among female sex workers in San Francisco; (2) to characterize social capital among networks of female sex workers in San Francisco; and (3) to investigate whether diminished social capital is associated with increased risk of prevalent HIV, STI and hepatitis among these networks. With these data, Dr. Cohan intends to develop and evaluate culturally-appropriate, communitydriven prevention interventions for sex workers. Dr. Cohan has assembled a multidisciplinary team spanning the fields of epidemiology, psychology, and medical anthropology to ensure success of this project.

Project Title: STRUCTURE/FUNCTION STUDIES OF S100 PROTEINS AND P53 Principal Investigator & Institution: Weber, David J.; Associate Professor; Biochem and Molecular Biology; University of Maryland Balt Prof School Baltimore, Md 21201 Timing: Fiscal Year 2003; Project Start 01-FEB-1999; Project End 31-JAN-2007 Summary: (provided by applicant): During the last 3 years, (i) high yields (>30 mg purified protein/liter media) of S 100B, S 100A 1, S 100A3, CAN19, mtsl, p53, p53(324393), p53(303-393), p53(303-367), hepatitis B viral protein X (HBVX), SUMO-1, Cterminal fragment of myosin IIA(1900-1961), and the HMG A box of the high mobility group protein- 1 (HMG-1) were prepared in minimal media as necessary for isotopic labeling (2H, 13C, 15N, etc). (ii) We determined the solution structures of apo-S 100B, apo-S 100A 1, calcium-bound S 100B, and calcium-bound S 100B in a complex with the negative regulatory domain of p53 (residues 367-388). (iii) We showed that dimeric S 100B is the physiologically relevant oligomerization state of S 100B, and that S 100B inhibits protein kinase C (PKC) phosphorylation of p53. (iv) We developed cellularbased assays for p53 and showed that p53 function is inhibited in tumor cell lines as a result of the calcium-dependent p53-S 100B interaction. This interaction includes both the oligomerization and negative regulatory domains at the C-terminus of p53. We plan to continue characterizing the calcium-dependent interaction of S 100B with the tumor suppressor protein p53. The effects that p53 phosphorylation, acetylation, and sumoylation have on S 100B binding will be examined. The binding of zinc to S 100B and heterodimer formation (i.e. S 100A 1/S 100B, CaN 19/S 100B and mts 1/S 100B etc.) will also be characterized. These data are necessary to determine whether covalent modifications of p53 and/or other S100B binding events affect S100B-p53 complex formation and function We will also determine the 3D structure of calcium-bound S100B complexed with a larger construct of p53 that includes both the oligomerization and the C-terminal regulatory domains of p53 (residues 324-393; Kd=24nM). Heteronuclear relaxation measurements for backbone and sidechain resonances are planned for all of the structures that we solve (or have solved) in order to clarify how calcium and p53 binding affects the dynamics of S100B (and p53). These dynamic data will be used in a search for small molecule inhibitors of the S 100B-p53 interaction. Lastly, the 3D solution structures of other proteins that bind the C-terminus of p53 will be examined including the metastasis protein 1 (mts 1), S100A3, the CaN 19 tumor suppressor, the hepatitis B viral protein (HBVX), the p53 binding domain of BLM, and the A box ofHMG-1. It will be interesting to determine whether these or other p53-binding proteins enhance and/or compete with the S 100B-p53 interaction.

Project Title: TARGETED GENE DELIVERY AND EXPRESSION IN HEPATOCYTES Principal Investigator & Institution: Wu, George Y.; Chief, Div of Gastroenterology; Medicine; University of Connecticut Sch of Med/Dnt Bb20, Mc 2806 Farmington, Ct 060302806 Timing: Fiscal Year 2001; Project Start 01-JAN-1990; Project End 31-JAN-2006 Summary: (Adapted from the Applicant's Abstract): In the previous grant period, we developed a multicomponent DNA carrier that, through the incorporation of endosomolytic peptides, is capable of releasing targeted nucleic acids directly to the cytoplasm of hepatocytes. Using multicomponent carriers, the efficiency of delivery of nucleic acids into cells was increased by 3 orders of magnitude, and the amount of DNA introduced into the nuclei in animals was increased 1 to 2 orders of magnitude compared to the originally described system. Recently, we have developed new approaches to enhance integration of targeted genes in cell culture resulting in persistent transgene expression. The objective of the current project is to take advantage of these advances to evaluate a novel therapeutic strategy against hepatitis B viral infection: transfection-mediated therapeutic selection. The hypothesis is: integrative transfection of antiviral genes will result in continuous inhibition of HBV gene expression, and block production of viral antigens. Under the pressure of host cellmediated immune response against cells bearing HBV antigens, there will be a selective survival advantage to transfected cells and their progeny. The antiviral agents are proposed to be generated from genes whose products are directed against unique features of the HBV life cycle, blocking translation, and replication. These areas distinguish viral processes from those of the mammalian host in order to achieve efficacy without toxicity. Candidates will be screened using stable HBV expression models in cell culture first to identify optimal constructs. Agents will be targeted to liver by complexation with multicomponent carriers, and also by genetic engineering into chimeric adeno-associated viral vectors all with integration enhancement capability. After optimization and comparison in an HBV cell culture model system, antiviral agents will be used to test the therapeutic approach in an animal model of HBV infection. Agents will be prepared against analogous sequences in the Woodchuck Hepatitis Virus (WHV), a homologous hepadna virus. Efficacy of long-term inhibition of HBV gene expression and replication, and evidence of selective survival advantage of cells bearing integrated antiviral genes will be determined over the time course, and optimal agents compared.

Project Title: TRANSCRIPTION ACTIVATION BY HIV, TAT, HTLV TAX & HBV PX Principal Investigator & Institution: Green, Michael R.; Professor; Molecular Medicine; Univ of Massachusetts Med Sch Worcester Office of Research Funding Worcester, Ma 01655 Timing: Fiscal Year 2001; Project Start 01-SEP-1990; Project End 31-AUG-2005 Summary: (from investigator's abstract): This is a competitive renewal application. The previous grant was for studying how the trancriptional regulatory proteins of three pathogenic viruses activate transcription, specifically, the Tat protein of human immunodeficiency virus type 1 (HIV-1), the Tax protein of human T-cell leukemia virus type 1 (HTLV-1), and the pX protein of hepatitis B virus (HBV). In this application, the applicant seeks to understand in greater detail the mechanism of action of these viral regulatory proteins and their role in viral replication and human disease. The rationale

84

Hepatitis B

for the proposal relies heavily on two relatively new technologies. First, the chromatin immunoprecipitation (ChIP) assay, which allows for the detection of specific proteins that are physically associated with DNA in living cells. Second, the genome-wide expression analysis using high density DNA microarrays, which enables the analysis of transcription profiles of a large array of human genes. The specific aims are: (1) To understand in greater detail how HIV-1 Tat stimulates transcription in vitro and in vivo. The investigator has identified a Tat cofactor, Tat-SF1, and has shown that it is a general transcription elongation factor. A second elongation factor has been implicated, AIEF, and remains to be identified. Tat-SF1 and AIEF and the mechanisms of Tat activation in vivo will be investigated further. (2) To study how HTLV-1 Tax and HBV pX regulates DNA binding of cellular bZIP proteins. The investigator has shown that Tax and pX dramatically increase the DNA binding activity and alter the target selectivity of a wide variety of cellular proteins that possess a basic region-leucine zipper (bZIP) DNA binding domain, through promotion of dimerization. Experiments are proposed to undersstand the basis of altered DNA binding specificity, the cellular proteins involved, and details of the DNA-protein interactions. (3) To analyze how HTLV-1 Tax and HBV pX activate transcription in vivo and transform cells. To test the prediction of different models of how these proteins activate transcription, to identify cellular proteins involved in the activation, and to identify cellular genes activated that may contribute to disease. (4) To understand the mechanism of BEF action. The investigator has identified a nuclear protein BEF (for bZIP-enhancing factor) which is required for bZIP prtoein functions, work synergistically with Tax and pX. However, BEF works by a different mechanism, as a molecular chaperone. Experiments are proposed to further study the mechanism of BEF action.

Project Title: TRANSIENT GLUCOSYLATION OF GLYCOPROTEINS Principal Investigator & Institution: Parodi, Armando J.; Instituto De Investigaciones Bioquimicas Bioquimicas Fundacion Campomar Buenos Aires, Timing: Fiscal Year 2001; Project Start 15-AUG-1990; Project End 31-MAY-2003 Summary: Protein glycosylation is initiated in the endoplasmic reticulum (ER) by transfer of an oligosaccharide (Glc3Man9GlcNAc2) to nascent polypeptide chains. Processing of the oligosaccharide by glucosidases I and II yields unglucosylated oligosaccharides that are reglucosylated by the UDP-Glc:glycoprotein glucosyltransferase (GT) only if the protein moieties of glycoproteins are not properly folded, as GT behaves as a sensor of glycoprotein conformations. Interaction of monoglucosylated glycoproteins (created by partialdeglucosylation of the transferred compound or by GT-mediated reglucosylation) with ER lectins (calnexin and calreticulin) facilitates acquisition of the proper tertiary structures and prevents secretion of not yet properly folded species. Folding facilitation mediated by the interaction of monoglucosylated glycoproteins and ER lectins is necessary for production of infective viral particles (vesicular stomatitis virus, HIV, hepatitis B virus) and also for the viability of yeasts when under severe ER stress conditions. The long term objective of the proposal is to gain thorough information of the structural features leading to the monoglucosylated glycoprotein-lectin interaction as this knowledge will undoubtedly provide useful information for understanding and/or preventing production of the etiological agents of several diseases. Within this long term objective, the Specific Aims of the proposed research are: a) to define the structural elements exclusively exposed in misfolded glycoproteins whose recognition is required for GTmediated glucosylation; b) to define GT domains responsible for substrate donor (UDP-

Studies

85

Glc), and substrate acceptor (N-oligosaccharide) recognition and for the exclusive glucosylation of misfolded species and c) to study the possibility that folding facilitation mediated by the interaction of cruzipain, a cysteine proteinase from the protozoan parasite Trypanosoma cruzi and ER lectins could be absolutely necessary for parasite infectivity. T. cruzi is the causative agent of a disease endemic in Latin America (Chagas's disease) that affects about 16 million people. Cruzipain has been identified as one of the T. cruzi virulence factors and has been found to be the only glycoprotein interacting with ER lectins in the protozoon.

Project Title: VIRAL INDUCED HCC?

ANTIGEN

GLYCOSYLATION--MARKER

FOR

HBV

Principal Investigator & Institution: Block, Timothy M.; Professor and Director; Biochem & Molecular Pharmacol; Thomas Jefferson University Office of Research Administration Philadelphia, Pa 191075587 Timing: Fiscal Year 2002; Project Start 01-APR-2002; Project End 31-MAR-2004 Summary: (provided by applicant): In this exploratory program we propose to test the hypothesis that oligosaccharides associated with serum proteins can accurately serve as biomarkers. Oligosaccharide profiles of hepatitis B surface antigens (HBsAg), purified from patient sera of different clinical populations, will be generated using novel HPLC sequencing technology that can reproducibly quantitate greater than 0.1 percent of an individual oligosaccharide in a glycan pool. Our sample population will consist of patients at risk for, or diagnosed with, hepatocellular carcinoma (HCC). The data generated will allow HBsAg oligosaccharides to be compared between different patient populations and the potential diagnostic value to be assessed. Alteration in the oligosaccharides associated with glycoproteins is one of the many molecular changes that accompany malignant transformations. In the case of HCC, an increase in fucosylation of secreted liver proteins is a common alteration. This increase in fucosylation has been postulated as a marker for HCC, however, the proteins of interest that show this alteration are typically found in low abundance (e.g. alpha fetoprotein). Our hypothesis is that, in cases where infection with hepatitis B virus (HBV) leads to the development of HCC, the viral glycoproteins (present up to mg/ml concentration) themselves may display aberrant oligosaccharides that could serve as early detection markers for HCC. Infection with HBV is the major etiology of HCC and, although HCC is a less common cancer in the USA, recent studies have shown that the incidence of HCC is rising both in the USA and worldwide. In addition, HCC is one of the most aggressive malignancies with prognosis being poor due to the late diagnosis. With the paucity of organ donors for liver transplantation and the small number of treatable patients (due to, in part, late diagnosis), early diagnosis will allow intervention at an earlier stage. We expect that this pilot study will firstly generate preliminary data to support the stated hypothesis; secondly, the study will allow the feasibility of a larger study to be determined, and thirdly, the parameters required to design a larger study to determine the value of oligosaccharide structures as potential markers of disease status will be obtained.

Hepatitis B

Timing: Fiscal Year 2001; Project Start 06-MAY-1994; Project End 31-MAR-2004 Summary: Defining the complex mechanisms of viral oncogenesis requires a broad understanding in at least three areas of research: molecular and cellular biology, immunology, and virology. It is the goal of the proposed training program to provide graduate students and postdoctoral fellows a challenging and enriched scientific environment in which both formal and informal training within these three broad, but interrelated areas can occur. The breadth of the scientific interests of the training faculty create a blend of research areas, many of which incorporate virus systems to dissect the molecular events that occur within the normal versus the cancer cell. The specific research programs include (a) molecular and cellular biology-regulation of cell growth and gene expression, oncogenes, signal transduction, and mechanisms of neoplastic transformation; (b) immunology-expression, oncogenes, signal transduction, and mechanisms of neoplastic transformation; (b) immunology; and (c) virology-molecular studies of virus replication, assembly, oncogenesis, pathogenesis, latency, and gene regulation using adeno, cytomegalo, hepatitis B, herpes simplex, papilloma, papova, and retroviruses. The trainers associated with the proposed training grant have their primary academic appointments within the Department of Microbiology and Immunology. However, each of the trainers is associated with multiple interdisciplinary graduate programs which cross departmental and college boundaries. Graduate students eligible for appointment on the training grant may be associated with one of several graduate programs including Chemical Biology, Cell and Molecular Biology, Genetics, Microbiology and Immunology, Molecular Medicine, and Neurosciences. The potential of the trainers to recruit students from such a variety of programs helps to insure that a significant pool of highly qualified students will be available for appointment to the training grant. The training program for graduate students and postdoctoral fellows includes a dynamic research environment that has excellent research and core support facilities and faculty research laboratories with productive and well funded research programs. The research and training environment is further enhanced by numerous interactions among the various laboratories as well as journal clubs, student seminars, and visiting scientist seminar programs. Finally, the research areas of emphasis within the training program provide a broad foundation on which a creative student and postdoctoral fellow can base a productive career in research in the area of citruses and cancer.

Project Title: VITAMIN A THERAPY IN PRETERM INFANTS: VACCINE RESPONSE Principal Investigator & Institution: Ballow, Mark; Professor of Pediatrics; Pediatrics; State University of New York at Buffalo Suite 211 Ub Commons Amherst, Ny 14228 Timing: Fiscal Year 2001; Project Start 15-SEP-1999; Project End 31-AUG-2003 Summary: The role of vitamin A as an immune modulatory factor has been the focus of many studies both in animals and man. Epidemiologic studies emphasize that vitamin A is essential for supporting the immune system against infection. Despite many therapeutic improvements in recent years, infection still remains a major problem in very low birth weight (VLBW) pre-term infants. Pre-term infants have lower plasma vitamin A (retinol) levels and limited hepatic reserves compared to full term infants. Vitamin A deficiency may lead to increased susceptibility to infection in pre-term infants. Hepatitis B immunization in the neonatal period offers an excellent opportunity to determine what effects vitamin A supplementation has in pre-term infants on their antibody immune response to this vaccine. VLBW pre-term infants less than 1500g (less

than 32 weeks gestation) will be randomized into two treatment groups: vitamin A supplemented and placebo (saline). The vitamin A treatment group will receive 2000 IU of retinyl palmitate by intramuscular injection starting on postnatal day 2 and thereafter on alternate days for 28 days. Plasma vitamin A levels will be closely monitored for toxicity. Plasma immunoglobulins and antibodies to HbsAg and tetanus toxoid will be quantified by ELISA after the second and third doses of hepatitis B vaccine. These results will be correlated with changes in CD4+ T-cell subsets as defined by their cytokine secretion profile and the proportion of naive (CD45RA) to memory (CD45R0) T-cells as analyzed by flow cytometry. Acceleration in the maturation of T-cells (naive to memory), and augmentation in the proportion of intracellular cytokine producing Tcells will provide a mechanism for the enhancement in the humoral immune responses to hepatitis B vaccine by vitamin A supplementation. Finally, the type and number of infections in the NICU and to 9 months of age will be recorded to determine if vitamin A supplementation affects the incidence and severity of infection in early infancy. Vitamin A supplementation may be useful in pre-term infants in augmenting B-cell immune responses to infectious agents and in their response to vaccines. These factors could lead to decreased morbidity and mortality of pre-term infants during early postnatal life. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen •

Project Title: WOMEN DRUG USERS, THEIR MALE PARTNERS AND HIV RISK Principal Investigator & Institution: Tortu, Stephanie A.; Associate Professor; National Development & Res Institutes Research Institutes, Inc. New York, Ny 10010 Timing: Fiscal Year 2001; Project Start 15-DEC-1999; Project End 30-NOV-2003 Summary: In the US, the number of women drug users diagnosed with AIDS continues to increase, and levels of sexual risk behaviors remain high. Theoretical and empirical work has indicated that drug using women's relationships with male sex partners are focal points of risky sexual behavior and drug use. To inform HIV prevention efforts, there is a need to explore women's relationship with their main sexual partners, and determine how relationship factors affect HIV risk. Drug using women (primarily African-American and Puerto Rican) will be recruited from the streets of East Harlem. Those who report use of crack/cocaine, injected drugs, of 360 couples (n=720) will complete structured interviews. In addition to demographic and socioeconomic characteristics, drug use, and HIV risk behaviors, the interview will measure: 1) dyadic factors (e.g., characteristics of the relationship, drug use patterns, interpersonal processes); 2) individual attributes (e.g., history of physical/sexual abuse, psychological functioning, HIV serostatus); and 3) situation specific variables in most recent sex events. HIV, hepatitis B, and Hepatitis C testing and counseling will be offered. Multivariate statistical techniques will be used to determine the effects of dyadic factors, individual attributes, and their interaction on HIV risk behaviors. The prevalence of HIV, HBV, and HCV infections will be assessed, as will the couples will be compared in terms of drug use patterns, interpersonal processes, relationship satisfaction, and partner support. Results of this project will be used to develop interventions targeted at drug using couples to reduce HIV risk behaviors and assist those who are living with HIV.

With PubMed Central, NCBI is taking the lead in preservation and maintenance of open access to electronic literature, just as NLM has done for decades with printed biomedical literature. PubMed Central aims to become a world-class library of the digital age. 5 The value of PubMed Central, in addition to its role as an archive, lies in the availability of data from diverse sources stored in a common format in a single repository. Many journals already have online publishing operations, and there is a growing tendency to publish material online only, to the exclusion of print.

The National Library of Medicine: PubMed One of the quickest and most comprehensive ways to find academic studies in both English and other languages is to use PubMed, maintained by the National Library of Medicine.6 The advantage of PubMed over previously mentioned sources is that it covers a greater number of domestic and foreign references. It is also free to use. If the publisher has a Web site that offers full text of its journals, PubMed will provide links to that site, as well as to sites offering other related data. User registration, a subscription fee, or some other type of fee may be required to access the full text of articles in some journals.

6 PubMed was developed by the National Center for Biotechnology Information (NCBI) at the National Library of Medicine (NLM) at the National Institutes of Health (NIH). The PubMed database was developed in conjunction with publishers of biomedical literature as a search tool for accessing literature citations and linking to full-text journal articles at Web sites of participating publishers. Publishers that participate in PubMed supply NLM with their citations electronically prior to or at the time of publication.

CHAPTER 2. NUTRITION AND HEPATITIS B Overview In this chapter, we will show you how to find studies dedicated specifically to nutrition and hepatitis B.

Finding Nutrition Studies on Hepatitis B The National Institutes of Health’s Office of Dietary Supplements (ODS) offers a searchable bibliographic database called the IBIDS (International Bibliographic Information on Dietary Supplements; National Institutes of Health, Building 31, Room 1B29, 31 Center Drive, MSC 2086, Bethesda, Maryland 20892-2086, Tel: 301-435-2920, Fax: 301-480-1845, E-mail: [email protected]). The IBIDS contains over 460,000 scientific citations and summaries about dietary supplements and nutrition as well as references to published international, scientific literature on dietary supplements such as vitamins, minerals, and botanicals.7 The IBIDS includes references and citations to both human and animal research studies. As a service of the ODS, access to the IBIDS database is available free of charge at the following Web address: http://ods.od.nih.gov/databases/ibids.html. After entering the search area, you have three choices: (1) IBIDS Consumer Database, (2) Full IBIDS Database, or (3) Peer Reviewed Citations Only. Now that you have selected a database, click on the “Advanced” tab. An advanced search allows you to retrieve up to 100 fully explained references in a comprehensive format. Type “hepatitis B” (or synonyms) into the search box, and click “Go.” To narrow the search, you can also select the “Title” field.

7 Adapted from http://ods.od.nih.gov. IBIDS is produced by the Office of Dietary Supplements (ODS) at the National Institutes of Health to assist the public, healthcare providers, educators, and researchers in locating credible, scientific information on dietary supplements. IBIDS was developed and will be maintained through an interagency partnership with the Food and Nutrition Information Center of the National Agricultural Library, U.S. Department of Agriculture.

CHAPTER 5. CLINICAL TRIALS AND HEPATITIS B Overview In this chapter, we will show you how to keep informed of the latest clinical trials concerning hepatitis B.

Recent Trials on Hepatitis B The following is a list of recent trials dedicated to hepatitis B.8 Further information on a trial is available at the Web site indicated. •

A Comparison Study of the Efficacy of Adefovir and Tenofovir for the Treatment of Lamivudine-Resistant Hepatitis B Virus Condition(s): HIV Infections; Hepatitis B Study Status: This study is currently recruiting patients. Sponsor(s): National Institute of Allergy and Infectious Diseases (NIAID) Purpose - Excerpt: The purpose of this study is to find out if adding adefovir dipivoxil (ADV) or tenofovir disoproxil fumarate (TDF) with lamivudine (3TC) has an effect on hepatitis B virus (HBV) infection, and to study the tolerability and safety of the drugs. HBV infection that lasts for a long time is an important cause of death, occurrence of disease, and a source of potential new infections around the world. Treatment with nucleoside analogue drugs such as 3TC can help inhibit HBV, but these drugs cannot always control the infection for a long period of time. Failure of 3TC to suppress HBV is particularly common in people who are also being treated for human immunodeficiency virus (HIV). To help people whose HBV infections cannot be controlled with 3TC, researchers need to identify and study other anti-HBV drugs. Both ADV and TDF are drugs that can inhibit HBV. This study will compare the combination of ADV and 3TC with the combination of TDF and 3TC to determine which drug combination is most effective in people who are infected with both HBV and HIV. Phase(s): Phase II Study Type: Interventional

Frequency of Parenteral and Non-Parenteral Exposures to Blood Among Healthcare Workers at the Clinical Center, NIH and at Seven Academic Hospitals in Japan Condition(s): Hepatitis B; Hepatitis C; HIV Infection Study Status: This study is currently recruiting patients. Sponsor(s): Warren G Magnuson Clinical Center (CC) Purpose - Excerpt: Following guidelines issued by the Centers for Disease Control, the Clinical Center implemented a Universal Precautions policy in November 1987 in an attempt to reduce healthcare workers' risks for occupational exposures to bloodborne pathogens. All hospital personnel whose jobs entailed potential exposure to patients' blood and body substances were required to attend a training session and complete a written examination. Based on data from surveys conducted before and twelve months after training in Universal Precautions, the frequency of cutaneous exposure to blood decreased by 50% in temporal association with implementation of Universal Precautions. Staff at the Clinical Center are required to take a refresher course in Universal Precautions annually. The prevalence of bloodborne infections is high in Japan; however, Universal Precautions are not widely practiced in Japan. This study is designed: 1) to evaluate and compare nurses' knowledge of the epidemiology, pathogenesis, occupational risks, and appropriate prevention strategies for managing patients infected with bloodborne pathogens in the healthcare setting in seven university hospitals in Japan and at the Clinical Center of the National Institutes of Health in the US; 2) to compare self-reported levels of compliance with existing infection control recommendations designed to limit risk for exposure to bloodborne pathogens in all four institutions; 3) to compare self-reported frequencies of cutaneous exposures to blood at the four hospitals in the study; and 4) to evaluate the effect of educational intervention on nurses perceived compliance with recommendations and on the frequency of self-reported exposures to blood.

Lamivudine and Adefovir to Treat Chronic Hepatitis B Condition(s): HBV; Hepatitis B; Hepatitis; Liver Study Status: This study is currently recruiting patients. Sponsor(s): National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) Purpose - Excerpt: This study will evaluate the safety and effectiveness of lamivudine plus adefovir versus adefovir alone to treat chronic hepatitis B infection. The Food and Drug Administration has approved lamivudine for the treatment of hepatitis B. However, the drug is not effective in all patients, and many of those in whom it initially works develop resistance after 1 to 3 years. Adefovir is an experimental drug that inhibits replication of the hepatitis B virus (HBV). Adefovir used alone may be adequate to provide sustained suppression of the virus and improvement in liver disease. However combining two anti-viral agents may be superior to using one alone, similar to the strategy employed for the treatment of AIDS. This study will test whether the combination of lamivudine and adefovir is better than adefovir alone for the treatment of chronic hepatitis B. Patients 18 years of age and older, who have been infected with HBV for at least 6 months, may be eligible for this study. Candidates may not have received lamivudine treatment in the past 6 months or prior treatment with adefovir and must not be taking other anti-viral treatments for their hepatitis. They will have a blood test to confirm HBV infection. Participants will be admitted to the NIH Clinical Center for 2 to 3 days for a medical evaluation, including a history and physical examination, blood and urine tests, 24-hour urine collection, chest X-ray, electrocardiogram (EKG), abdominal ultrasound and a liver biopsy if one has not been done within the last year. This procedure involves obtaining a small sample of liver tissue through a needle placed in the liver. One to 2 weeks after the evaluation, patients will be randomized to begin taking 100 milligrams/day of lamivudine and 10 mg/day of adefovir, both in pill form or 10 mg of adefovir alone. Therapy will continue for at least 12 months. Follow-up clinic visits will be scheduled weekly for the first month, then every 4 to 8 weeks for the rest of the treatment period. The visits will involve a history and physical examination and blood tests. At the end of 1 year, patients will be evaluated in the Clinical Center with the same tests done at the beginning of the study. Patients who have not improved with treatment will stop taking the treatment and will be evaluated in the clinic once every 4 weeks for another 6 months. Patients who show an improvement in their liver injury may continue taking lamivudine and adefovir or adefovir alone for 4 more years, as long as they continue to improve with the medication. Progress will be evaluated with blood tests for HBV levels and liver enzymes. If the test results show no continued improvement or are negative for hepatitis B antigens, therapy will be stopped. Patients who continue treatment for 5 years will be readmitted at year 4 to the Clinical Center for another medical evaluation and liver biopsy to assess the effects of treatment at that time. After the 5 years all patients will stop therapy at and be followed with regular clinic visits for at least 6 months.

Prevention of Recurrent Hepatitis B after Liver Transplantation Condition(s): Hepatitis B; Cirrhosis; Acute Liver Failure; Hepatocellular Carcinoma Study Status: This study is currently recruiting patients.

Clinical Trials 213

Sponsor(s): National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) Purpose - Excerpt: Hepatitis B accounts for approximately 5000 deaths per year in the United States. Liver transplantation offers the only hope for patients who develop endstage liver disease. Early results of liver transplantation for hepatitis B were poor with recurrence rate of 80% and 1-year survival of only 50%. Recent studies found that preventive therapy using hepatitis B immune globulin (HBIG) or antiviral medications such as lamivudine can reduce the recurrence rate to roughly 30% with accompanying improvement in survival. However, HBIG when given as intravenous infusion in high doses is very expensive, while long-term use of lamivudine is associated with drug resistance. Some studies found that preventive therapy using both HBIG and lamivudine may decrease recurrence rate to less than 10% but the dose and duration of HBIG needed when used in combination with lamivudine is not clear. Adefovir, a new antiviral medication, is effective against lamivudine resistant hepatitis B but its role in liver transplantation is uncertain because of the risk of kidney damage. Many studies showed that the risk of recurrent hepatitis B is related to the viral load before transplant. Thus, it may be possible to tailor the preventive therapy according to the risk. The aim of this study is to establish the most cost-effective preventive therapy for recurrent hepatitis B after liver transplantation.

Adefovir Dipivoxil to Treat Hepatitis B in HIV-Infected Patients Condition(s): Hepatitis B; HIV Infection Study Status: This study is no longer recruiting patients. Sponsor(s): National Institute of Allergy and Infectious Diseases (NIAID) Purpose - Excerpt: This study will evaluate the safety and effectiveness of adding the experimental drug adefovir dipivoxil to lamivudine for treating hepatitis B virus (HBV) infection in HIV-infected patients with liver cirrhosis. Adefovir inhibits HBV by interfering with replication of the virus's genetic material. In some people, the drug has been active against strains of HBV that are resistant to lamivudine; it may also have some activity against HIV. HIV-infected patients 21 years of age and older with chronic hepatitis B infection and liver cirrhosis who have received lamivudine treatment for at least 1 year may be eligible for this 48-week study. Candidates will be screened with a complete medical history, blood tests and a 24-hour urine collection. Blood tests include HLA typing (a test of genetic markers on white blood cells that permit specialized immunology studies). Within 4 weeks, candidates who appear eligible for the study will have a physical examination and medical history, an abdominal ultrasound (imaging test using sound waves) to check for cancer of the liver, chest X-ray and electrocardiogram (EKG). Blood and urine tests will also be done, and women who can become pregnant will have a pregnancy test. Patients who meet the study criteria and decide to participate will then start treatment with one 10-mg adefovir pill per day by mouth. In addition, patients will continue to take all other medications prescribed by their doctor. Follow-up clinic visits will be scheduled as follows: - Days 1, 3, 5, 7, 10 and 21 - Blood will be drawn for specialized immunology tests and to measure blood levels of HIV and HBV. - Weeks 2, 4, 8, 12, 16, 20, 24, 28, 32, 36, 40, 44 - Blood and urine (single

216 Hepatitis B

sample) tests will be done to determine the side effects of adefovir and its effect on the HBV infection. - Week 48 or early termination (end of study) - Blood tests (including tests for hepatitis C and D), abdominal ultrasound and a 24-hour urine collection to evaluate kidney function will be done. - Monthly visits beyond week 48 - Based on the HBV response to treatment and the availability of the drug from the sponsor, patients may be offered to extend their treatment with adefovir. Those who continue will have monthly follow-up visits for blood and urine (single sample) tests.

Lamivudine and Adefovir to Treat Chronic Hepatitis B Infection in People With and Without HIV Infection Condition(s): HIV Infections; Chronic Hepatitis B Study Status: This study is no longer recruiting patients. Sponsor(s): National Institute of Allergy and Infectious Diseases (NIAID) Purpose - Excerpt: This study will evaluate the safety and effectiveness of adefovir plus lamivudine for chronic hepatitis B infection in people with and without HIV infection. Lamuvidine, an FDA-approved treatment for hepatitis B infection, also works against HIV. In some patients, the hepatitis B virus (HBV) continues to reproduce despite lamivudine treatment. Adefovir is an experimental drug that inhibits HBV replication and may work against some strains of the virus that have become resistant to lamivudine. Patients 21 years of age or older with active hepatitis B infection despite treatment with lamivudine for at least 1 year may be eligible for this 48-week study. Patients both with or without HIV infection may participate. Candidates will be screened with a medical history, blood and urine tests, liver ultrasound exam, electrocardiogram (EKG) and chest X-ray. Participants will have a physical examination, review of their medical history, blood tests, and a 24-hour urine collection. They will be admitted to the hospital for a liver biopsy to determine if they can receive the study drug. For this procedure, the patient is given a sedative for relaxation. The skin over the biopsy is numbed with an anesthetic and the biopsy needle is passed rapidly into and out of the liver to collect a tissue specimen. Patients are monitored in the hospital

overnight for possible complications. After discharge, they return home and begin taking the study medications. Patients will be randomized to two treatment groups. One group will take 10 milligrams/day of adefovir by mouth, and the other will take a placebo-a lookalike pill with no active ingredient. Both groups will also take 150 mg lamivudine by mouth and L-carnitine pills or liquid. Patients with HIV infection will continue to take antiretroviral therapy as well. Patients will be followed in the clinic at study weeks 2, 4, 8, 12, 16, 20, 24, 28, 32, 36, 40 and 44 for blood and urine tests to determine the safety of the drug and to evaluate the response to treatment. On week 48, a repeat 24-hour urine test and repeat liver biopsy will be done. At the end of the 48 weeks, patients may continue to receive adefovir for another 48 weeks and possibly longer. All those who participate in this extension phase will receive active adefovir, regardless of whether they had previously taken adefovir or placebo. All patients will have the option to enroll in a separate study to examine the levels of HBV (and levels of HIV in HIV-infected patients) in the blood immediately after starting treatment and to determine if these initial levels can predict later outcome. This involves seven additional visits, for which participants will be compensated. At these visits, blood will be drawn on study days 0 (before starting drug treatment), 1, 3, 5, 7, 10 and 21 for HIV and HBV viral loads and specialized immunology tests.

Chronic

Hepatitis

D;

Glomerulonephritis;

Study Status: This study is no longer recruiting patients. Sponsor(s): National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) Purpose - Excerpt: Chronic hepatitis B is a disease of the liver caused by the hepatitis B virus. It affects nearly 1 million Americans. Approximately 25% of patients with chronic hepatitis B will develop liver cirrhosis and 5% of patients will develop liver cancer. Presently, two medications have been shown effective in the treatment of hepatitis B: lamivudine and alpha interferon. Alpha interferon (an antiviral drug that acts through the immune system) is given by injection once daily or three times a week for four to six months. Lamivudine (also known as 3-thiacytidine: 3TC) is an antiviral medication given as a pill once a day for twelve months. These treatments have been known to provide long-term improvement in one third of patients receiving them. In previous research, the drug lamivudine was shown to stop the growth of the hepatitis B virus and to lead marked decreases in the levels of hepatitis B virus and to improvements in the disease in 50 to 70% of patients. However, once lamivudine therapy was discontinued the virus returned to levels noted before the therapy began. In those studies lamivudine was given for 3 to 12 months then discontinued. This study will investigate the safety and effectiveness of long-term therapy with lamivudine. This study will select 60 patients diagnosed with hepatitis B. After a thorough medical examination and liver biopsy, subjects will be given lamivudine. The drug will be taken by mouth in tablet form (100 mg) once a day for up to 5 years. Subjects will undergo regular check-ups and after 1 year of therapy be admitted to the Clinical Center for another medical examination and liver biopsy to assess progress. Patients who have benefitted from the

218 Hepatitis B

therapy will continue taking the medication for up to 5 years. A third liver biopsy will be done during the last year of treatment. The effectiveness of lamivudine will be determined by whether levels of hepatitis B virus decrease in the blood, whether liver enzymes improve, and whether inflammation and scarring decreases in the liver biopsies.

The Tolerance of HIV-Infected Patients with Herpes Group Virus Infections to Oral Doses of FIAU Condition(s): Herpes Simplex; HIV Infections; Hepatitis B Study Status: This study is completed. Sponsor(s): National Institute of Allergy and Infectious Diseases (NIAID); Oclassen Pharmaceuticals Purpose - Excerpt: To determine the tolerance of HIV-infected patients to TID oral doses of FIAU syrup at 4 different dose levels. To determine the peak and trough blood levels of FIAU and its metabolites during two weeks of oral dosing with FIAU. The pyrimidine nucleoside analog FIAC and its primary deaminated uracil metabolite FIAU are highly and specifically active compounds in vitro against several herpes group viruses, particularly herpes simplex virus (HSV) types 1 and 2, varicella zoster (VZV), and cytomegalovirus (CMV), as well as hepatitis B virus (HBV). Since FIAU is the primary metabolite of FIAC and the administration of FIAU simplifies the metabolism of FIAC, it is anticipated from clinical studies of FIAC that FIAU will be tolerated at least as well as FIAC. A single-dose, pharmacokinetic (blood level) study showed that FIAC, when taken orally, is readily absorbed into the bloodstream, and most of it is converted to FIAU. Daily oral doses are expected to provide concentrations of FIAU exceeding the in vitro minimum inhibitory concentration for nearly all the herpes group viruses.

CHAPTER 6. PATENTS ON HEPATITIS B Overview Patents can be physical innovations (e.g. chemicals, pharmaceuticals, medical equipment) or processes (e.g. treatments or diagnostic procedures). The United States Patent and Trademark Office defines a patent as a grant of a property right to the inventor, issued by the Patent and Trademark Office.9 Patents, therefore, are intellectual property. For the United States, the term of a new patent is 20 years from the date when the patent application was filed. If the inventor wishes to receive economic benefits, it is likely that the invention will become commercially available within 20 years of the initial filing. It is important to understand, therefore, that an inventor’s patent does not indicate that a product or service is or will be commercially available. The patent implies only that the inventor has “the right to exclude others from making, using, offering for sale, or selling” the invention in the United States. While this relates to U.S. patents, similar rules govern foreign patents. In this chapter, we show you how to locate information on patents and their inventors. If you find a patent that is particularly interesting to you, contact the inventor or the assignee for further information. IMPORTANT NOTE: When following the search strategy described below, you may discover non-medical patents that use the generic term “hepatitis B” (or a synonym) in their titles. To accurately reflect the results that you might find while conducting research on hepatitis B, we have not necessarily excluded non-medical patents in this bibliography.

Patents on Hepatitis B By performing a patent search focusing on hepatitis B, you can obtain information such as the title of the invention, the names of the inventor(s), the assignee(s) or the company that owns or controls the patent, a short abstract that summarizes the patent, and a few excerpts from the description of the patent. The abstract of a patent tends to be more technical in nature, while the description is often written for the public. Full patent descriptions contain much more information than is presented here (e.g. claims, references, figures, diagrams, etc.). We will tell you how to obtain this information later in the chapter. The following is an 9Adapted

Adenovirus vector with multiple expression cassettes Inventor(s): Wang; Danher (Mt. Pleasant, SC) Assignee(s): GenPhar, Inc. (Mt. Pleasant, SC) Patent Number: 6,544,780 Date filed: June 2, 2000 Abstract: Genetic vaccines and methods are provided for enhancing the immunity of a host such as a human to one or more pathogens. In one embodiment, a recombinant benign virus is provided as the genetic vaccine. The recombinant virus comprises: an antigen sequence heterologous to the recombinant virus that encodes a viral antigen from a pathogenic virus, expression of the viral antigen eliciting an immune response directed against the viral antigen and cells expressing the viral antigen in a host upon infection of the host by the recombinant virus; and an immuno-stimulator sequence heterologous to the recombinant virus that encodes an immuno-stimulator whose expression in the host enhances the immunogenicity of the viral antigen. The recombinant virus is replication-incompetent and does not causes a malignancy naturally associated with the pathogenic virus in the host. The genetic vaccines can be used for immunizing a host against a wide variety of pathogens, such as HIV, Ebola virus, hepatitis B virus, hepatitis C virus, influenza virus, pathogenic bacteria and parasites.

Patents 225

Excerpt(s): This invention relates to vaccines for stimulating immune responses in human and other hosts, and, in particular, relates to recombinant viruses that express heterologous antigens of pathogenic viruses, such as Ebola, HIV, hepatitis, and influenza viruses. Current techniques for developing vaccines are largely based on the concept of using denatured virus or purified viral proteins made from bacteria. These types of vaccines may be effective for only a limited number of infectious agents, and the protection rates are limited. For viruses that contain membrane (envelope) glycoproteins (GPs), including the Ebola virus and the HIV virus, use of denatured virus or purified viral proteins often does not work satisfactorily. There may be several reasons for this. First, the GPs of these viruses are sensitive to the denaturing procedures so that the epitopes of the proteins are altered by the denaturing process. Second, the sugar moieties of the GPs are important antigenic determinants for neutralizing antibodies. In comparison, proteins made in bacteria are not properly glycosylated and can fold into somewhat different structures that can have antigenecities different from those of the natural viral proteins. Further, many vaccines that are based on attenuated or denatured virus provide a weak immune response to poorly immunogenic antigens. In addition, the vaccine preparations frequently offer only limited protection, not lifelong immunity as desired. Web site: http://www.delphion.com/details?pn=US06544780__ •

Antibodies and other binding molecules specific for hepatitis B viral antigens Inventor(s): Paulij; Wilhelmina Petronella (Schijndel, NL), Van Kessel-Koens; Marjolijn Jacqueline (St. Oederode, NL) Assignee(s): Akzo Nobel N.V. (NL) Patent Number: 6,541,198 Date filed: January 13, 2000 Abstract: The present invention relates to antibodies and other binding molecules specific for hepatitis B viral antigens (HBV), peptides comprising epitopes recognized by such molecules, and cell lines capable of producing antibodies. The invention is further concerned with the use of such molecules in diagnosis of HBV. The invention further relates to a method for the diagnosis of hepatitis B, the method comprising contacting the sample suspected to contain hepatitis B particles or antigens with a specific binding molecule according to the invention. The invention further relates to an assay kit for the detection of a hepatitis B particle or antigen, the kit comprising a specific binding molecule of the invention and means for detecting whether the specific binding molecule is bound to a hepatitis B particle or antigen. Excerpt(s): The present invention relates to antibodies land other binding molecules specific for hepatitis B viral antigens (HBV), peptides comprising epitopes recognised by such molecules, and cell lines capable of producing antibodies. The invention is further concerned with the use of such molecules in diagnosis of hepatitis B virus (HBV). The virus that causes hepatitis B or serum hepatitis appears to infect only man and chimpanzees. Hepatitis B virus (HBV) infection in humans is widespread. The hepatitis infection is transmitted by three general mechanisms: (1) by parenteral inoculation of infected blood or body fluids, either in large amounts as in blood transfusions or in minute amounts as through an accidental skin prick; (2) by close family or sexual contact; and (3) by some mothers, who infected during pregnancy, transmit the virus to their new-born children. Under natural conditions, HBV is not highly contagious. Transmission by inhalation occurs rarely, if ever.

Antisense ogligonucleotides against Hepatitis B viral replication Inventor(s): Gerin; John L. (Bethesda, MD), Korba; Brent E. (Laurel, MD) Assignee(s): Georgetown University (Washington, DC) Patent Number: 6,503,533 Date filed: November 25, 1998 Abstract: Antisense oligonucleotides that hybridize to segments of the pres1, S, C, and.epsilon. regions of the hepatitis B virus (HBV) RNA pregenome inhibit replication of the virus. Pharmaceutical compositions which contain these oligonucleotides as the active ingredients are effective against HBV infection. Excerpt(s): The present invention was made utilizing funds from contracts NO1-AI72623 and NO1-AI-45179 between the National Institute for Allergy and Infectious Diseases and Georgetown University. The present invention relates to compositions for the treatment of Hepatitis B virus (HBV) infection. In particular, the invention relates to antisense oligonucleotides and their use to inhibit HBV replication. Hepatitis B virus, a member of the Hepadnaviridae family, is a blood-borne, hepatotropic pathogen which infects large numbers of people annually. In 1987 there were approximately 25,000 newly reported cases of disease attributable to HBV infection in the US. It is estimated that 60-70% of HBV infections lead to subclinical (asymptomatic) disease, and it is therefore probable that the actual number of new HBV infections each year is much higher. Of those infected with HBV, 90% make a full recovery, but 2-10% of infected patients develop chronic, persistent HBV infection. It is estimated that 1 million people in the US and 300 million people worldwide are chronically infected with HBV. In parts of Asia and Africa it is thought that between 5 and 20% of the population are chronically infected with HBV. Web site: http://www.delphion.com/details?pn=US06503533__

The present invention is also concerned with pharmaceutical compositions containing said combinations and their

Patents 227

use in the treatment of HBV infections including infections with HBV mutants bearing resistance to nucleoside and/or non-nucleoside inhibitors of the replication of the hepatitis B virus. Hepatitis B is a viral disease transmitted orally or parentally by contaminated material such as blood or blood products, contaminated needles, sexually, and vertically from infected or carrier mothers to their off-spring. In those areas of the world where the disease is common, vertical transmission at an early age results in a high proportion of infected individuals becoming chronic carriers of hepatitis B. An estimated 350 million people world-wide are chronically infected with hepatitis B and as many as 150 million may die from liver disease in the absence of intervention. Currently, the only established approach to treatment of hepatitis B is repeated injections of interferon, which may be associated with unpleasant side effects, and produces a long lasting response in only one third or less of those treated. Interferon is an immune modulator designed to boost the disease fighting ability of the immune system. Web site: http://www.delphion.com/details?pn=US06432966__ •

228 Hepatitis B

preventing and/or treating viral infections such as hepatitis B, influenza A and B, and HIV which employ robustaflavone or derivatives thereof alone or in combination with at least one antiviral agent such as 3TC. Viruses, an important etiologic agent in infectious disease in humans and other mammals, are a diverse group of infectious agents that differ greatly in size, shape, chemical composition, host range, and effects on hosts. After several decades of study, only a limited number of antiviral agents are available for the treatment and/or prevention of diseases caused by viruses such as hepatitis B, influenza A and B and HIV. Because of their toxic effects on a host, many antiviral agents are limited to topical applications. Accordingly, there is a need for safe and effective antiviral agents with a wide-spectrum of anti-viral activity with reduced toxicity to the host. Since the identification of the human immunodeficiency virus (HIV) as the causative agent of AIDS,.sup.36,46 the search for safe and effective treatments for HIV infection has become a major focus for drug discovery groups around the world. Investigations into the molecular processes of HIV have identified a number of macromolecular targets for drug design, such as HIV-1 reverse transcriptase (HIV-RT), protease and integrase enzymes, and regulatory proteins (e.g., TAT and REV). Other targets are enzymes which aid in virus attachment and fusion. HIV-RT is an essential enzyme in the life cycle of HIV, which catalyzes the transcription of HIV-encoded single-stranded RNA into double-stranded DNA. Furthermore, the RNA-dependent DNA polymerase function of HIV-RT does not have an analogous process in mammalian metabolism, and thus is a suitable target for a chemotherapeutic agent.

Combination therapy method for treating chronic hepatitis B Inventor(s): Horwitz; David L. (Hillsborough, CA) Assignee(s): SciClone Pharmaceuticals, Inc. (San Mateo, CA) Patent Number: 6,495,521 Date filed: January 17, 2001 Abstract: The present invention is aimed at augmenting the success rate of using thymosin in treatment of chronic hepatitis B, by employing a combination therapy using thymosin with antiviral agents which are effective in inhibiting DNA synthesis or DNA polymerase during replication of the hepatitis B virus. Excerpt(s): The instant invention relates to a method for treating chronic hepatitis B infections. More specifically, the instant invention relates to a method for treating chronic hepatitis B infections using both thymosin and an antiviral drug. Hepatitis B is the most prevalent form of hepatitis and is the second most common infectious disease worldwide. Worldwide estimates of those chronically infected with hepatitis B virus (HBV) are in excess of 300,000,000. The disease is caused by the hepatitis B virus, a DNA virus. The virus is transmitted through blood transfusions, contaminated needles, sexual contact and vertical transmission from mother to child. Moreover, a significant number of people are infected by unknown means. Carriers of the virus can exhibit various forms of disease, one of which is chronic hepatitis B. Approximately 50% of the carriers show chronic inflammatory changes in the liver and, of these, about 50% have histopathologic changes, which are termed "chronic active hepatitis", that may lead to fibrosis and ultimately to cirrhosis and progressive liver failure. Carriers without chronic inflammatory changes may also develop chronic active hepatitis. Liver cancer develops in about 10 to 30% of hepatitis B carriers. It has been estimated that

Excerpt(s): This application is a 371 of International Application PCT/EP99/01406, filed Mar. 4, 1999, which claims priority from GB 9805105.5, filed Mar. 9, 1998 and GB 9813561.9, filed Jun. 23, 1998. This invention relates to novel vaccine formulations, methods for preparing them and their use in therapy. In particular the present invention relates to combination vaccines for administration to adolescents. Genital herpes is estimated to occur in about 5 million people in the U.S.A. alone with 500,000 clinical cases recorded every year (primary and recurrent infection). Primary infection typically occurs after puberty and is characterised by the localised appearance of painful skin lesions, which persist for a period of between 2 to 3 weeks. Within the following six months after primary infection 50% of patients will experience a recurrence of the disease. About 25% of patients may experience between 10-15 recurrent episodes of the disease each year. In immunocompromised patients the incidence of high frequency recurrence is statistically higher than in the normal patient population. Web site: http://www.delphion.com/details?pn=US06451320__

Expression of immunogenic hepatitis B surface antigens in transgenic plants Inventor(s): Arntzen; Charles Joel (Ithaca, NY), Mason; Hugh S. (Ithaca, NY), Richter; Elizabeth (Ithaca, NY), Thanavala; Yasmin (Williamsville, NY) Assignee(s): Boyce Thompson Institute for Plant Research (Ithaca, NY) Patent Number: 6,551,820 Date filed: December 23, 1999 Abstract: Plant expression vectors comprising at least two expression cassettes are provided which function to reduce transcriptional silencing of polynucleotide expression. Further, novel plant expression vectors for expression of immunogenic polypeptides, including HBsAg, are provided. The plant expression vectors can be used to produce immunogenic polypeptides, including HBsAg, in edible plant tissues. The

230 Hepatitis B

edible plant tissues can be used to elicit an immune response in humans and animals when the plant tissues are consumed. Excerpt(s): The present invention relates to oral vaccines, particularly those provided by edible plants. The invention employs genetic engineering techniques to produce transgenic plants capable of expressing immunogenic polypeptides, including hepatitis B antigen (HBsAg) in quantities sufficient to elicit an immune response in a human or animal that consumes all or a part of the plant. A vaccine for hepatitis B was the first "new generation" recombinant vaccine licensed by the FDA for human use. The immunogenic subunit in this formulation is produced by expressing the gene encoding HBsAg in recombinant yeast; the protein is purified from the genetically engineered yeast and is used for parenteral delivery. In the developed world, the recombinant vaccine has displaced the use of an earlier vaccine derived from the plasma of infected individuals. Both plasma-derived and rHBsAg vaccines are shown to be reasonably safe and effective in high-risk adult populations and newborn infants. However, the cost of the rHBsAg vaccine prevents its extensive availability in developing countries. The envelope of the hepatitis B virus (HBV) contains three size classes of proteins that share carboxy-terminal sequences. These proteins, called hepatitis B surface antigens (HBsAgs), include large (L, containing a pre-S.sub.2 domain), medium (M.sub.1 containing a pre-S.sub.1 domain), and small (S, containing only the S domain) size classes. All three proteins are found in infectious virions (often referred to as Dane particles) recovered as 42 nm spheres from the serum of infected patients. Serum samples also contain empty spherical particles averaging 22 nm, which contain primarily S class proteins. Mammalian cell lines transfected exclusively with DNA encoding the S protein release 20 nm empty spheres similar to those from infected cells. Moreover, yeast cells transformed with the same gene form analogous spheres, which are found to be equally immunogenic as the 22 nm spheres from infected cells. The yeast-derived material forms the active constituents of the currently available commercial vaccines ENGERIX (SKB) and RECOMBIVAX (Merck).

Glucamine compounds for treating hepatitis virus infections Inventor(s): Bryant; Martin L. (Carlisle, MA), Mueller; Richard A. (Glencoe, IL), Partis; Richard A. (Evanston, IL) Assignee(s): G.D. Searle & Co. (Chicago, IL) Patent Number: 6,515,028 Date filed: February 14, 2000 Abstract: N-Substituted glucamine compounds of Formula I are effective in treatment of hepatitis infections, including hepatitis B and hepatitis C. In treating hepatitis infections, the compounds of Formula I may be used alone, or in combination with another antiviral agents selected from among nucleosides, nucleotides, immunomodulators, immunostimulants or various combinations of such other agents. Excerpt(s): The present invention relates to methods and compositions for treating hepatitis virus infections, especially hepatitis B virus infections, in mammals, especially humans. The methods comprise administering glucamine compounds in combination with nucleoside antiviral agents, nucleotide antiviral agents, mixtures thereof, or immunomodulating/immunostimulating agents. Such combinations of anti-hepatitis viral agents show unexpected efficacy in inhibiting replication and secretion of hepatitis

viruses in cells of mammals infected with these viruses. Over half the biologically important proteins are glycosylated and that glycosylation may vary with disease. Based upon this information, the use of drugs to control of glycosylation patterns, glycoforms, changes or rates of change will have a a biochemical effect and may provide a beneficial therapeutic result. Control of glycolipid and glycoprotein sugar patterns as well as their synthesis and degradation leads to basic physiological effects on mammals including humans, agricultural animals and pets. Possibly, this is through influences on, for example, N-linked glycans, O-linked glycans, glucosoaminoglycans, glycosphingolipids, glycophospholipids, lectins, immuneoglobulin molecules, antibodies, glycoproteins and their biochemical intermediates or conversion products. Modification of glycosalation site occupancy influences receptor and enzyme binding site specificity, selectivity, capacity, protein folding, enzyme activity, kinetics and energetics. Glycosidase and glycosyltransferase systems are two biochemical mechanisms that are suggested to affect such systems (Dwek, Raymond A., Glycobiology: Toward Understanding the Function of Sugars, Chemical Reviews, 96, 683-720(1996). Iminosugars are anti-viral drugs that can induce the inhibition of viral interactions with and within mammalian cells such as attachment to cells, penetration of cells, maturation within cells and release from cells. The mechanism involved may be glucosidase inhibition, glycosyl transferase inhibition or others as discussed above. Web site: http://www.delphion.com/details?pn=US06515028__ •

Hepatitis B surface antigen vaccine Inventor(s): Thoma; Hans A. (Munchen, DE) Assignee(s): Medeva Holdings B.V. (Amsterdam, NL) Patent Number: 6,589,530 Date filed: June 7, 1995 Abstract: HBV surface antigen particles, prepared by recombinant DNA technology are described, said particles being composed of epitopes from the group of surface peptides and/or core peptide of non-A, non-B hepatitis virus, hepatitis A virus, or hepatitis virus B. Respective particles are especially characterized by a composition of different epitopes selected from pre-S and S peptides. There are also described DNA-sequences, plasmids, and cell lines coding for respective HBV surface antigen particles as well as a new vaccine containing the same. Excerpt(s): The invention relates to Hepatitis B surface antigen ("HBs antigen" or "HBsAG") particles which are composed of polypeptides prepared by recombinant DNA processes, DNA sequences coding for these polypeptides and cell lines for the expression of the same. The present invention relates especially to new particles having increased immunogenicity. Advances in vaccine production techniques have made it possible to synthesize polypeptides corresponding to the HBs antigen in bacteria, yeast and mammalian cells. Transcription of eukaryotic genes in bacteria and yeast, however, adversely affects the efficaciousness of these polypeptides as antigens due to several drawbacks concerning the glycosilation and secretion of the polypeptides and composition of the particle formed therefrom. For example, in the case of the Hepatitis B virus, the polypeptide antigens produced in vivo are heavily glycosilated (Gerlich, 1984: J. Virol.: 52 (2), 396). In prokaryotes, glycosilation is not an essential process so that polypeptides produced by genetically engineered bacteria are either not glycosilated or are incompletely glycosilated. In either case, polypeptides corresponding to HBsAg, when expressed in bacteria, do not raise antibodies which will see HBsAg sufficiently

232 Hepatitis B

well for an effective vaccine. Although yeast as a eukaryotic host is capable of more complete glycosilation, polypeptides corresponding to HbsAg expressed in yeast share the same deficiency as in the case of bacterial expression.

Hepatitis vaccines containing 3-0-deacylated monophoshoryl lipid A Inventor(s): Garcon-Johnson; Nathalie Marie-Josephe Claude (Wavre, BE), Hauser; Pierre (Chaumont-Gistoux, BE), Thiriart; Clothilde (Brussels, BE), Voet; Pierre (Izel, BE) Assignee(s): SmithKline Beecham Biologicals (s.a.) (Rixensart, BE) Patent Number: 6,620,414 Date filed: August 21, 2001 Abstract: A vaccine formulation for the treatment or prophylaxis of hepatitis, especially hepatitis B, infections is provided comprising the hepatitis antigen and a suitable carrier such as alum in combination with 3-O-deacylated monophosphoryl lipid A. Combination vaccines including the vaccine formulation are also described. Excerpt(s): The present invention relates to novel vaccine formulations, methods for preparing them and to their use in therapy. In particular the present invention relates to novel formulations for treating Hepatitis infections and to combination vaccine formulations including a Hepatitis vaccine component. Viral hepatitis, caused by the A, B, C, D, and E hepatitis viruses, is a very common viral illness. Via the B and C viruses, in particular, it is also responsible for many cases of liver cancer. Thus the development of effective vaccines is critical and, despite notable successes, is still an on-going task. A review on modern hepatitis vaccines, including a number of key references, may be found in the Lancet, May 12th 1990 at page 1142 ff (Prof A. L. W. F. Eddleston).

In vitro activity assay for human hepatitis B virus (HBV) DNA polymerase, and its use for screening for inhibitors of HBV DNA polymerase Inventor(s): Chen; Wei Ning (Singapore, SG), Leong; Ai Lin (Singapore, SG), Lim; Gek Keow (Singapore, SG), Oon; Chong Jin (Singapore, SG) Assignee(s): Government of the Republic of Singapore (Singapore, SG) Patent Number: 6,593,082 Date filed: June 18, 2001 Abstract: The present invention provides an in vitro activity assay for human hepatitis B virus (HBV) DNA polymerase, which comprises using, as the 5' oligonucleotide in PCR amplification of HBV DNA polymerase from a sample, an oligonucleotide into which has been incorporated the SP6 viral polymerase promoter, directly transcribing and translating the PCR products in the presence of a radio-labelled agent and measuring the priming of the HBV DNA polymerase. The present invention also provides the use of such an assay to assay activity of various serum samples, to screen for inhibitors of the HBV DNA polymerase and to test and/or screen potential anti-HBV drugs for their ability to inhibit DNA priming activity of human HBV DNA polymerase. Excerpt(s): Polymerases are enzymes of fundamental importance to living organisms. They are responsible for the synthesis of nucleic acids and their transformation into other nucleic acids necessary for the synthesis of proteins. Polymerases are, therefore, found in all types of cells including the causative DNA virus for hepatitis B virus (HBV). Although such active vaccination programme has resulted in a decrease of HBV infection in the population, an increasing number of mutations located within the `a` epitope have been emerging. These vaccine-induced HBV mutants are of concern, as they are capable of escaping the currently available immuno-based diagnostic system and able to replicate independently. The fact that mutations on the `a` epitope of HBsAg give rise to amino acid substitutions in the overlapping HBV DNA polymerase, particularly by their location within the reverse transcriptase domain, may imply that these vaccine-induced mutants have altered reverse transcriptase activity, a key factor for the viral replication.

Method for immunization against hepatitis B Inventor(s): Mancini; Maryline (Paris, FR), Michel; Marie-Louise (Paris, FR) Assignee(s): Institut de la Sante et de la Recherche Medicale (Paris, FR), Institut Pasteur (Paris, FR) Patent Number: 6,429,201 Date filed: May 12, 2000 Abstract: Nucleotide vector composition containing such vector and vaccine for immunization against hepatitis. Nucleotide vector comprising at least one gene or one complementary DNA coding for at least a portion of a virus, and a promoter providing for the expression of such gene in muscle cells. The gene may be the S gene of the hepatitis B virus. A nucleotide vector composition when administered to even chronic HBV carriers is capable of breaking T cell tolerance to the surface antigens of hepatitis B virus. A vaccine preparation containing said bare DNA is injected into the host previously treated with a substance capable of inducing a coagulating necrosis of the muscle fibers. Excerpt(s): The present invention relates to compositions for inducing protective antibodies against hepatitis. It also relates to a vector comprising a nucleotide sequence coding for at least a portion of a virus protein, which is capable of being expressed in muscle cells. In addition, the invention relates to compositions capable of inducing a T cell response in chronic HBV carriers. Hepatitis B is a widespread and serious international health problem. In addition to causing acute hepatitis and liver damage, the hepatitis B virus (HBV) can cause cirrhosis and hepatocellular carcinoma (Davis, Hum. Molec. Genet. 2:1847-1851 (1993)). The HBV is a 42-nm particle (Dane particle)

Patents 235

consisting of a lipoprotein envelope enclosing a core protein (capsid) and the viral genome, which contains only four genes (S, C, P, X). The major (or small) envelope protein, which includes the surface antigen of HBV (HBsAG) is encoded by the S gene and is organized into dimers of one glycosylated and one unglycosylated polypeptide (Petersen, J. Biol. Chem. 256:6975-6983 (1981)). Present in smaller amounts are the middle and large envelope proteins, which are encoded by the pre-S2 and S or pre-S1, pre-S2 and S genes, respectively. The predominant form of HBsAg secreted by infected cells is not the Dane particle, however, but 22-nm particles or filaments, which are empty viral envelopes composed solely or predominantly of major (small) envelope protein and sometimes small amounts of middle and large proteins (Maupas, Lancet 1:1367-1370 (1976)). The 22-nm particles are seen to persist in the plasma of chronic carriers (Davis, 1993). Web site: http://www.delphion.com/details?pn=US06429201__ •

Mutant human hepatitis B viral strain and uses thereof Inventor(s): Chen; Wei Ning (Singapore, SG), Lim; Gek Keow (Singapore, SG), Oon; Chong Jin (Singapore, SG), Zhao; Yi (Singapore, SG) Assignee(s): Government of Republic of Singapore (Singapore, SG) Patent Number: 6,558,675 Date filed: April 30, 2001 Abstract: An isolated strain of Hepatitis B virus designated Human Hepatitis B Virus Surface Antigen-`S`-133 Oon Strain (Methionine to Threonine) of Cell. Also, an isolated nucleic acid encoding a polypeptide which is a mutant major surface antigen of a strain of hepatitis B virus, such polypeptide having an amino acid sequence which differs

236 Hepatitis B

from the amino acid sequence of a major surface antigen of a wild type hepatitis B virus in that the amino acid at position number 133 of such polypeptide is a threonine rather than methionine. Excerpt(s): Throughout this application, various references are referred to within parentheses. Disclosures of these publications in their entireties are hereby incorporated by reference into this application to more fully describe the state of the art to which this invention pertains. The present invention concerns the human hepatitis B virus genome, isolated from hepatocellular carcinoma (HCC), and with a mutation at amino acid residue 133 (Methionine to Threonine) within the major surface antigen, its nucleotide sequence, the deduced amino acid sequence of the four major proteins, antigen, antibody, detection systems, development of effective vaccines, and antiviral agents. One of the major causes of chronic liver diseases is hepatitis B viral infection. First discovered in 1963 as a human virus that is transmitted parenterally, chronic hepatitis B viral infection has been most commonly implicated in serological undefined pathogenesis of HCC. Despite the fact that hepatitis B virus does not display features of a complete viral oncogene, its involvement in the development of HCC can be attributed to various aspects of its interaction with host hepatocyte cells. These include the promiscuous transcriptional activity of the smallest viral protein, X, which enhances the expression level of many cellular target genes including proto-oncogenes. On the other hand, integrated viral DNA in the host chromosomes is regularly found in HCC patients. There is also evidence for an active role in the development of HCC by the major surface antigen. This protein has served as the main detection marker for carriers of hepatitis B virus. The most antigenic epitope is a highly conserved region spanning 23 amino acid residues and located from amino acid position 124 to 147 of the major surface antigen. This small region designated as the group specific determinant "a" is found in all subtypes and isolates of hepatitis B viral genomes. Its antigenic properties seem due to its proposed double loop structure, to which the vaccine-induced neutralizing antibody binds. Web site: http://www.delphion.com/details?pn=US06558675__ •

Nucleosides with anti-hepatitis B virus activity Inventor(s): Gosselin; Gilles (Montpellier, FR), Imbach; Jean-Louis (Montpellier, FR), Schinazi; Raymond F. (Decatur, GA), Sommadossi; Jean-Pierre (Birmingham, AL) Assignee(s): Emory University (Atlanta, GA), University of Alabama Research Foundation, Inc. (Birmingham, AL) Patent Number: 6,525,033 Date filed: November 22, 1999 Abstract: A method for treating HBV infections via administration of 2', 3' dideoxynucleoside compounds. Excerpt(s): This invention is in the area of methods for the treatment of hepatitis B virus (also referred to as "HBV") that includes administering an effective amount of one or more of the active compounds disclosed herein, or a pharmaceutically acceptable derivative or prodrug of one of these compounds. Hepatitis B virus has reached epidemic levels worldwide. After a two to six month incubation period in which the host is unaware of the infection, HBV infection can lead to acute hepatitis and liver damage, that causes abdominal pain, jaundice, and elevated blood levels of certain enzymes. HBV can cause fulminant hepatitis, a rapidly progressive, often fatal form of

Patents 237

the disease in which massive sections of the liver are destroyed. Patients typically recover from acute viral hepatitis. In some patients, however, high levels of viral antigen persist in the blood for an extended, or indefinite, period, causing a chronic infection. Chronic infections can lead to chronic persistent hepatitis. Patients infected with chronic persistent HBV are most common in developing countries. By mid-1991, there were approximately 225 million chronic carriers of HBV in Asia alone, and worldwide, almost 300 million carriers. Chronic persistent hepatitis can cause fatigue, cirrhosis of the liver, and hepatocellular carcinoma, a primary liver cancer. In western industrialized countries, high risk groups for HBV infection include those in contact with HBV carriers or their blood samples. The epidemiology of HBV is in fact very similar to that of acquired immunodeficiency syndrome, which accounts for why HBV infection is common among patients with AIDS or HIV-associated infections. However, HBV is more contagious than HIV. Web site: http://www.delphion.com/details?pn=US06525033__ •

Peptides for inducing cytotoxic T lymphocyte responses to hepatitus B virus Inventor(s): Chisari; Francis V. (Del Mar, CA), Ferrari; Carlo (Parma, IT), Missael; Gabriele (Parma, IT), Penna; Amalia (Parma, IT) Assignee(s): The Scripps Research Institute (La Jolla, CA) Patent Number: 6,607,727 Date filed: May 20, 1996 Abstract: Peptides are used to define epitopes that stimulate HLA-restricted cytotoxic T lymphocyte activity against hepatitis B virus antigens. The peptides are derived from regions of HBV polymerase, and are particularly useful in treating or preventing HBV

238 Hepatitis B

infection, including methods for stimulating the immune response of chronically infected individuals to respond to HBV antigens. Excerpt(s): Cytotoxic T lymphocytes (CTLs) play an essential role in fighting cells infected with viruses, intracellular bacteria and parasites, and tumor cells. They do so by direct cytotoxicity and by providing specific and nonspecific help to other immunocytes such as macrophages, B cells, and other T cells. Infected cells or tumor cells process antigen through intracellular events involving proteases. The processed antigen is presented on the cellular surface in the form of peptides bound to HLA class I molecules to T cell receptors on CTLs. MHC class I molecules can also bind exogenous peptides and present them to CTLs without intracellular processing. At the present time it is difficult to accurately predict from the sequence of an antigenic protein how the protein will be processed and which peptide portions will bind HLA class I molecules and be presented to CTLs. Binding motifs have been predicted for some HLA class I molecules based on sequence analysis of peptides eluted from these molecules (Falk et al., Nature 351:290 (1991)). Further, of the peptides that are processed and do bind to HLA class I, which ones will contain CTL-recognizable epitopes is not yet predictable. Hepatitis B Virus ("HBV") is a non-lytic virus which has currently infected approximately 250 million people worldwide. HBV infection in adults typically leads to an acute disease in the majority of cases, and to a chronic disease state in a minority of patients. This ratio of acute to chronic is reversed when the infection occurs close to the time of birth. There is an increased incidence of hepatocellular carcinoma in chronic HBV infection. A small percentage of individuals who are infected with HBV in adulthood develop fulminant hepatitis associated with a strong immune response with high lethality.

Excerpt(s): The present invention relates to pharmaceutical compositions for the treatment of hepatitis B virus (HBV) infection. In a study reported by Neurath, et al. [A. Neurath, et al., J. Exp. Med., Vol. 175, pp. 461-469 (1992)] hIL-6 was shown to bind the pS1 (aa 21-47) segment of the HBV envelope.

Pharmaceutical formulation useful for the treatment of hepatitis B, hepatitis C and other viral infections of the liver and a process for its preparation Inventor(s): Thyagarajan; Sadras Panchatcharam (Chennai, IN) Assignee(s): University of Madras (Chennai, IN) Patent Number: 6,589,570 Date filed: December 12, 2000 Abstract: The invention disclosed in this application relates to a pharmaceutical formulation prepared from the biotyped variety of the medicinal plant, Phyllanthus amarus which is useful for the treatment of Hepatitis B (both acute and chronic), Hepatitis C (both acute and chronic) and other related viral infections of the liver with antihepatotoxic and liver cell regenerating potentials and immunomodulating properties. The invention confirms, that when pars of the biotyped variety of the medicinal plant, Phyllanthus amarus are extraceted separately with a polar solvent alone, polar solvent and water in specific ratios and water alone and when such extracts are mixed together, the resultant formulation has all the essential antiviral and biological properties, while the individual polar or aqueous extracts alone does not possess one or more of these properties. The present invention also relates to a process for the preparation of the above said new pharmaceutical formulation with biological and chemical standardisation protocols. Excerpt(s): This invention relates to a pharmaceutical formulation useful for the treatment of Hepatitis B and Hepatitis C and other viral infections of liver. This invention particularly relates to a pharmaceutical formulation useful for the treatment of acute and chronic Hepatitis B & C virus infections prepared from the Indian biotyped medicinal plant, Phyllanthus amarus. This invention also relates to a process for the preparation of the pharmaceutical formulation useful for the treatment of acute and chronic Hepatitis B and Hepatitis C and other viral infections of the liver from the medicinal plant Phyllanthus amarus. It is needless to stress the need for a s drug that would keep the liver functioning at its optimum or the one that would be selectively active against the currently known etiological agents of acute and chronic viral diseases of the liver. This is important because the disease of the liver throw the entire human body out of gear. The exciting alphabet of viral Hepatitis includes a wide range of totally unrelated often highly unusual pathogenic human viruses like Hepatitis A virus (HAV), Hepatitis B virus (HSV), Hepatitis C virus (HCV), Hepatitis D virus (HDV), Hepatits E virus (HEV) etc. Of the viruses it has been clearly established that HBV, HCV and HDV are the ones that are associated with the development of chronic persistent/active hepatitis, cirrhosis of the liver and even hepatocellular carcinoma besides being associated with fulminant hepatitis and sub acute hepatic failure. The natural disease course in HBV is being summarized to understand the need for the

240 Hepatitis B

effective management and treatment of Hepatitis B in a country. For normal adults with low viral production and an early immune response, the disease course is self limiting and usually asymptomatic (60-80% of all HBV infections). Individuals who replicate the virus in larger quantities, with a relatively late immune response have a self-limiting symptomatic acute hepatitis. Irrespective of whether initially symptomatic or asymptomatic, the infection becomes chronic in 5-10% of the individuals, 20-30% of them developing clinical sequelae such as chronic hepatitis, cirrhosis or hepatoma within years or decades. In neonates, however, the immune defence is still lacking (induction of tolerance), so that infected individuals do not develop acute hepatitis, but more of them become chronic camers (80-90%). Such carriers also progress frequently to chronic clinical sequelae faster. Between these two extremes are immunocompromised individuals, such as intravenous drug users, haemodialysis patients or transplant recipients, who are more likely to become chronic carriers than are healthy adults (1060%).

Polynucleotide decoys that inhibit MHC-II expression and uses thereof Inventor(s): Garovoy; Marvin R. (San Anselmo, CA), Hunt; C. Anthony (San Francisco, CA), Lim; Carol (San Francisco, CA) Assignee(s): The Regents of the University of California (Oakland, CA) Patent Number: 6,410,721 Date filed: January 5, 1999 Abstract: The invention is directed to a newly discovered class of polynucleotide decoys that is capable of competitively inhibiting the binding of transcription factors to the Xbox sequence. This binding is necessary for the expression of MHC-II genes. The invention is also directed to methods of preparing these polynucleotide decoys, and methods of use thereof. In particular, we have identified a class of polynucleotide decoys that mimic the X-Box of MHC-II and competitively bind the MHC-II transcription factor RF-X, resulting in the modulation of MHC-II antigen expression. Thus, the invention can be used to inhibit the expression of HLA molecules on the surface of donor cells or organs, in order to render them invisible to the host's immune system, or in methods of treating an individual with an autoimmune disease characterized by dysfunctional expression of an MHC class II antigen. Further, because of the role of RF-X in the expression of several viral proteins, the polynucleotide decoys of the invention can be used in methods of treating an individual infected with hepatitis B virus, or cytomegalovirus. Excerpt(s): This invention relates to nucleotide therapeutics, transplantation and immunology. More specifically, it relates to a newly discovered class of polynucleotide decoy molecules and methods for making cells and organs that are less likely to be rejected when transplanted into a recipient host using these polynucleotide decoys, which are capable of binding to a specific gene regulatory factor and reducing the expression of MHC class II transplantation antigens. Among gene products that relate to transplantation antigens are the products of the Human Leukocyte Antigen (HLA) complex, also known as the major histocompatibility complex (MHC), located on the short arm of chromosome 6. The HLA antigens are divided into two classes depending on their structure. The genetic loci denoted HLA-A -B, and -C code for the HLA Class I antigens, and HLA-DP, -DQ and -DR code for the HLA Class II antigens. Regulation of HLA class II antigen expression occurs in part through a series of promoter regions such

Recombinant VP2 parvoviral pseudo-particles encoding CTL or T-helper cell epitopes Inventor(s): Casal; Ignacio (Madrid, ES), Leclerc; Claude (Paris, FR), Lo-Man; Richard (Paris, FR), Rueda; Paloma (Madrid, ES), Sarraseca; Javier (Madrid, ES), Sedlik; Christine (Argenteuil, FR) Assignee(s): Immunologia Y Genetica Aplicada S.A. (Madrid, ES), Institut Pasteur (Paris, FR) Patent Number: 6,458,362 Date filed: August 30, 1996 Abstract: Attempts to generate modified viral pseudo-particles that are capable of stably incorporating heterologous antigenic determinants has encountered a number of difficulties including inhibition of pseudo-particle formation following epitope insertion and failure of the epitope to retain its native configuration. The present invention is directed toward recombinant viral pseudo-particles of the family Parvoviridae that stably encode heterologous epitopes. Hybrid virus-like particles (VLP) were prepared by self-assembly of a modified porcine parvovirus (PPV) VP2 capsid protein carrying a CD8.sup.+ or CD4.sup.+ T cell epitope in the amino terminus. Immunization of mice with hybrid pseudo-particles carrying a lymphocytic choriomeningitis virus (LCMV) nucleoprotein CTL epitope, without adjuvant, induced strong cytotoxic T lymphocyte (CTL) responses against both peptide-coated- or virus-infected-target cells.

242 Hepatitis B

Immunization of mice with hybrid pseudo-particles carrying a hepatitis B virus (HBV) T helper cell epitope, without adjuvant, induced strong T helper lymphocyte responses against the reporter epitope. These recombinant viral pseudo-particles are easily produced by the baculovirus expression system and, therefore, represent a promising and safe strategy to induce strong CTL and T-helper cell responses for the elimination of virus-infected cells. Excerpt(s): The present invention relates to recombinant viral pseudo-particles of a virus of the Parvoviridae family or of a related virus, useful in particular for inducing cytotoxic CD8.sup.+ T lymphocyte (CTL) and CD4.sup.+ helper T lymphocyte responses in vivo at a high level. Another object is the use of these pseudo-particles for the production of antitumoral vaccines or drugs. It also covers compositions comprising said pseudo-particles in a physiologically acceptable excipient and/or diluent. Web site: http://www.delphion.com/details?pn=US06458362__ •

Sequences and methods for detection of hepatitis B virus Inventor(s): Berger; Dolores M. (Baltimore, MD), Fort; Thomas L. (Finksburg, MD), Hellyer; Tobin J. (Owings Mills, MD), Nussbaumer; William A. (Timonium, MD) Assignee(s): Becton, Dickinson and Company (Franklin Lakes, NJ) Patent Number: 6,583,279 Date filed: January 26, 2001 Abstract: Primers and probes derived from the HBV DNA polymerase gene which facilitate detection and/or quantification of all presently known genotypes of HBV. Disclosed sequences may be used in a variety of primer and probe constructs for detection of HBV nucleic acids. Excerpt(s): The present invention relates to materials and methods for detection of Hepatitis B viral nucleic acids, in particular to probes and primers for detection of Hepatitis B in hybridization and amplification assays. Hepatitis B virus (HBV) is a partially double-stranded DNA virus which uses a unique replication mechanism incorporating an intermediate reverse transcription step. It is a major causative agent of chronic hepatitis and has been implicated in liver cirrhosis and hepatocellular carcinoma. Accurate identification and quantitation of HBV DNA is important not only for detecting HBV infection but also for monitoring the efficacy of antiviral treatments. A simple assay for HBV DNA using branched-DNA (bDNA) probes has been used for quantitation but was found to be insufficiently sensitive to monitor serum virus levels in patients undergoing antiviral treatment. More recently, HBV DNA has been detected and quantitated in more sensitive PCR assays, using both the Amplicor.TM. HBV Monitor test and the TaqMan.TM. technology for real-time detection. The present invention provides probes and primers for detection of HBV nucleic acids which may provide a more rapid and sensitive means for detecting HBV than immunological and culture-based methods. Further the probes and primers of the invention may allow more reliable detection of naturally occurring variants of HBV, as they are based on an analysis of conserved regions of the HBV DNA polymerase gene.

Single-stranded antibody against hepatitis B virus core protein, gene thereof, and therapeutic agent for hepatitis B containing these Inventor(s): Hayashi; Norio (Kawanishi, JP), Tohdoh; Naoki (Kobe, JP), Yamamoto; Hiroko (Higashiosaka, JP), Yamamoto; Masato (Hoover, AL) Assignee(s): Sumitomo Pharmaceuticals Company, Limited (Osaka-fu, JP) Patent Number: 6,562,599 Date filed: April 27, 2000 Abstract: A DNA characterized by coding for a single-stranded antibody capable of binding to a hepatitis B virus core protein: a single-stranded antibody coding for the DNA: a therapeutic agent for hepatitis B comprising the single-stranded antibody as the active ingredient; and a gene therapeutic agent containing the DNA as the active ingredient. Excerpt(s): The present invention relates to single-chain antibodies against hepatitis B virus core protein, genes thereof, and therapeutic agents for hepatitis B using the same. In particular, the present invention relates to single-chain antibodies characterized in that they inhibit DNA synthesis of hepatitis B virus by binding to the core protein of said virus, DNAs encoding said single-chain antibodies, vectors comprising said DNAs, transformants transformed with said vectors, a process for producing said single-chain antibodies, and therapeutic agents for hepatitis B using such single-chain antibodies or genes thereof. In Japan, hepatitis B virus (hereinafter sometimes abbreviated as HBV) accounts for a large part of the etiology of chronic hepatitis, as well as hepatitis C virus. Although the proportion of the virus carriers tends to decrease as a result of the recent preventive treatment by vaccination, there still exists a substantial number of patients with chronic hepatitis B, and medical treatments for this disease is quite important in terms of prophylaxis of primary hepatic cancer. As medical treatments for patients with chronic hepatitis B, those treatments that aim to exclude the virus by eliciting the host immunity, such as the interferon therapy, the steroid withdrawal therapy, and the propagermanium therapy, or the antiviral agent therapies (adenine arabinoside monophosphate, hereinafter sometimes abbreviated as ara-AMP), Lamivudine) are now being used. In the interferon therapy, however, a long-term clinical improvement cannot be observed, although a transient decrease in amount of serological markers of viral activities occurs. Likewise, although ara-AMP has been used with some effect, it is hard to say that the results are satisfactory at present. A treatment in which interferon and ara-AMP are combined and alternately administered exhibits neurotoxicity, and therefore has problems in its use. Furthermore, fulminant hepatitis B, which is one of the forms of acute hepatitis B, is a disease causing a high lethality, and there exist no effective therapeutic agents for this disease presently. Thus, although there is a strong need for developing an anti-hepatitis B virus therapy based on a different mechanism from those of conventional methods, no useful therapies have not yet been developed.

Steroid/thyroid hormone receptor-related gene which is inappropriately expressed in human hepatocellular carcinoma and which is a retinoic acid receptor Inventor(s): de The; Hugues Blaudin (Paris, FR), Dejean; Anne (Paris, FR), Marchio; Agnes (Paris, FR), Tiollais; Pierre (Paris, FR) Assignee(s): Institut Pasteur (Paris, FR) Patent Number: 6,531,585 Date filed: February 1, 1991 Abstract: A previously isolated hepatitis B virus (HBV) integration in a 147 bp cellular DNA fragment linked to hepatocellular carcinoma (HCC) was used as a probe to clone the corresponding complementary DNA from a human liver cDNA library. Nucleotide sequence analysis revealed that the overall structure of the cellular gene, which has been named hap, is similar to that of the DNA-binding hormone receptors. Six out of seven hepatoma and hepatoma-derived cell-lines express a 2.5 kb hap mRNA species which is undetectable in normal adult and fetal livers, but present in all nonhepactic tissues analyzed. Low stringency hybridization experiments revealed the existence of hap related genes in the human genome. The cloned DNA sequence is useful in the preparation of pure hap protein and as a probe in the detection and isolation of complementary DNA and RNA sequences. The hap protein is a retinoic acid (RA) receptor identified as RAR-.beta. Excerpt(s): This invention relates to nucleotide sequences, polypeptides encoded by the nucleotide sequences, and to their use in diagnostic and pharmaceutical applications. Primary hepatocellular carcinoma (HCC) represents the most common cancer, especially in young men, in many parts of the world (as in China and in much of Asia and Africa) (reviewed in Tiollais, et al., 1985). Its etiology was investigated mostly by epidemiological studies, which revealed that, beyond some minor potential agents such as aflatoxin and sex steroids, hormones, Hepatitis B virus (HBV) chronic infection could account for a large fraction of liver cancers (Beasley and Hwang, 1984). Liganddependent transcriptional activators, such as steroid or thyroid hormone receptors, have recently been cloned allowing rapid progress in the understanding of their mechanism of action. Nevertheless, there exists a need in the art for the identification of transcripts that may encode for activational elements, such as nuclear surface receptors, that may play a role in hepatocellular carcinoma. Such findings would aid in identifying corresponding transcripts in susceptible individuals. In addition, identification of transcripts could aid in elucidating the mechanisms by which HCC occurs.

Abstract: A method and composition for the treatment of HIV infection, HBV infection, or abnormal cellular proliferation in humans and other host animals is disclosed that includes the administration of an effective amount of a 1,3-oxaselenolane nucleoside or a pharmaceutically acceptable salt thereof, optionally in a pharmaceutically acceptable carrier. Excerpt(s): This invention is in the area of synthetic nucleosides, and is specifically directed to 1,3-oxaselenolane nucleosides and their pharmaceutical uses, compositions, and method of preparation. In 1981, acquired immune deficiency syndrome (AIDS) was identified as a disease that severely compromises the human immune system, and that almost without exception led to death. In 1983, the etiological cause of AIDS was determined to be the human immunodeficiency virus (HIV). In 1985, it was reported that the synthetic nucleoside 3'-azido-3'-deoxythymidine (AZT) inhibits the replication of human immunodeficiency virus. Since then, a number of other synthetic nucleosides, including 2',3'-dideoxyinosine (DDI), 2',3'-dideoxycytidine (DDC), 2',3'-dideoxy-2',3'didehydrothymidine (D4T), and (1S,4R)-4-[2-amino-6-cyclopropyl-amino)-9H-purin-9yl]-2-cyclopentene-1-me thanol succinate ("159U89"), have been proven to be effective against HIV. In general, after cellular phosphorylation to the 5'-triphosphate by cellular kinases, these synthetic nucleosides are incorporated into a growing strand of viral DNA, causing chain termination due to the absence of the 3'-hydroxyl group. They can also or alternatively inhibit the viral enzyme reverse transcriptase or DNA polymerase. Web site: http://www.delphion.com/details?pn=US06590107__ •

Synthetic peptides that bind to the hepatitis B virus core and e antigens Inventor(s): Sallberg; Matti (Alvsjo, SE) Assignee(s): Tripep AB (Huddinge, SE) Patent Number: 6,417,324 Date filed: April 21, 2000 Abstract: The present invention relates generally to the field of virology. More particularly, the invention relates to the discovery that peptides, which bind to the Hepatitis B virus (HBV) core and e antigens, can be used to inhibit HBV infection. Embodiments concern "binding partners", which include peptides, peptidomimetics, and chemicals that resemble these molecules that interact with HBV core and e antigens, biological complexes having HBV core and e antigens joined to said binding partners, methods of identifying such binding partners, pharmaceuticals having binding partners, and methods of treatments and prevention of HBV infection. Excerpt(s): The present invention relates generally to the field of virology. More particularly, the invention relates to the discovery that peptides that bind to the hepatitis B virus (HBV) core and e antigens can be used to inhibit HBV infection. Of the many viral causes of human hepatitis, few are of greater global importance than hepatitis B virus (HBV). Approximately 300 million people worldwide are chronically infected and some of these chronically infected individuals develop severe pathologic consequences including chronic hepatic insufficiency, cirrhosis, and hepatocellular carcinoma (HCC). (See Fields Virology, third ed., edited by Fields et al., LipponcottRaven Publishers, Philidelphia 1996 pp. 2703 and Lee et al., Cancer, 72:2564-7 (1993)). Primary infection may be asymptomatic (e.g, in chronically infected individuals) or may result in varying degrees of acute liver injury. (Milich et al., Springer Seminars in Immunopathology, 17:149-66 (1995)). The invention described herein concerns the

246 Hepatitis B

identification and manufacture of molecules that interact with HBcAg and/or HBeAg and thereby inhibit HBV infection or modulate a host immune system response or both. Molecules that interact with HBcAg and/or HBeAg, also referred to as "binding partners", are designed from fragments of antibodies and other proteins that interact with HBcAg and/or HBeAg. Accordingly, an amino acid sequence corresponding to the binding domains of monoclonal or polyclonal antibodies or proteins that bind HBcAg and/or HBeAg is used as a template for the design of synthetic molecules, including but not limited to, peptides, derivative or modified peptides, peptidomimetics, and chemicals. A preferred binding partner, for example, is a molecule called a "specificity exchanger", which comprises a first domain that interacts with HBcAg and/or HBeAg and a second domain that has an epitope for a high titer antibody, preferably an epitope on a pathogen or a toxin. The binding partners described herein can be manufactured by conventional techniques in peptide chemistry and/or organic chemistry. Web site: http://www.delphion.com/details?pn=US06417324__ •

Therapeutic nucleoside compound Inventor(s): Daluge; Susan Mary (Durham, NC) Assignee(s): SmithKline Beecham Corporation (Philadelphia, PA) Patent Number: 6,630,477 Date filed: October 12, 2001 Abstract: The present invention relates to (1R,4S)-4-(6-amino-9H-purin-9-yl)-2cyclopentene-1-methanol and its use in medical therapy for the treatment of hepatitis B infection. Excerpt(s): The present invention relates to (1R,4S)-4-(6-amino-9H-purin-9-yl)-2cyclopentene-1-methanol and its use in medical therapy. Hepatitis B virus (HBV) is a small DNA containing virus which infects humans. It is a member of the class of closely related viruses known as the hepadnaviruses, each member of which selectively infects either mammalian or avian hosts, such as the woodchuck and the duck. Recent insights into the mechanism of replication of the hepadnavirus genome indicate the importance of reverse transcription of an RNA intermediate, suggesting that the reverse transcriptase is a logical chemotherapeutic target. HBV is a viral pathogen of major worldwide importance. The virus is etiologically associated with primary hepatocellular carcinoma and is thought to cause 80% of the world's liver cancer. Clinical effects of infection with HBV range from headache, fever, malaise, nausea, vomiting, anorexia and abdominal pains. Replication of the virus is usually controlled by the immune response, with a course of recovery lasting weeks or months in humans, but infection may be more severe leading to persistent chronic liver disease outlined above. U.S. Pat. No. 4,916,224 discloses dideoxycarbocyclic nucleosides and their use in the treatment of HIV. Wang et al.

Topical immunomodulating compositions for treatment of aids, Hepatitis B & C, other infectious diseases, and cancer Inventor(s): Kaplan; Leonard L. (One Minuteman Ct., East Brunswick, NJ 08316), Levis; William R. (17 Weaver St., Staten Island, NY 10312) Assignee(s): none reported Patent Number: 6,455,586 Date filed: December 13, 1999 Abstract: Topical drug compositions, containing contact sensitizing agents as the active components of the subject patent compositions, can provide a pharmacological action that induces a delayed hypersensitization reaction resulting in stimulation of cell mediated immunity when applied to the skin. The preferred composition contains, but is not limited to, Diphenylcyclpropenone as a preferred embodiment of the class of contact sensitizing drugs applied to the skin in an optimally prepared pharmaceutical formulation with controlled absorption properties to reach the peripheral circulation resulting in increases in CD4+ helper T cells of benefit to immunocompromised patients. Excerpt(s): Contact sensitizers such as dinitrochlorobenzene (DNCB) have been reported to raise CD4+ helper T cell counts and reduce viral load in HIV positive patients (1,2). The DNCB was applied to the skin in 10% concentration dissolved in the volatile solvent acetone which resulted in unreliable and unpredictable contact sensitization reactions. Biologically, increases in CD+ helper T cell counts are accompanied by variable decreases in HIV retroviral replication as measured by human immunovirus ribonucleic acid (RNA) levels in dendritic cells that are the primary antigen presenting cells of the human immune system. It is the dendritic cells and microphages that are infected during the initial phases of human immunovirus growth in AIDS patients. Optimally formulated contact sensitizers when topically applied, can induce TH-1 type immunity by releasing cytokines including Interleukin 2,valuable in treating hepatitis B&C, and forms of cancer as well as AIDS. On the other hand, the medical use of the preferred contact sensitizer diphenylcyclopropenone has been limited primarily to the treatment of alopecia areata as disclosed in referenced U.S. Pat. No. 4,985,464 wherein the volatile solvent acetone with unreliable absorption properties was used as the formulation vehicle. Other contact sensitizers referenced in the literature (3) are, but not limited to, squaric acid dibutylester, urishiol, oxazolone, dinitrofluorobenzene, and paraphenylenediamine. In all referenced cases, the volatile solvent acetone with unreliable absorption characteristics was used as the drug delivery system for the contact sensitizers. Accordingly, there is a need for a more reliable stabilized composition in which the contact sensitizers are soluble and will be reliably and predictably absorbed through the skin to reach the aforementioned dendritic cells of the dermis. This invention provides compositions for the topical application of contact sensitizers in a unique topical pharmaceutical emulsion drug delivery system to reliably penetrate the epidermis of immunocompromised human patients in order to stimulate the release of CD4+ helper T cells and induce TH-1 type immunity by releasing cytokines including Interleukin 2, valuable in treating AIDS, Hepatitis B&C, other viral infectious diseases, and Cancer. The compositions contain controlled amounts of diphenyl-cyclopropenone, dinitrochlorobenzene, dinitrofluorobenzene, squaric acid dibutylester, urishiol, oxazolone, paraphenylene-diamine or other medically useful contact sensitizers emulfified in a non-toxic drug delivery system formula consisting of pharmaceutically acceptable non-volatile, non-ionic surfactants and pharmaceutically acceptable emollients at optimized levels wherein the contact sensitizer(s) are reliably absorbed through the epidermis to reach the dendritic cells in the dermis during the

248 Hepatitis B

early stages of viral infections in immunocompromised patients. A preferred embodiment of the invention includes diphenylcyclopropenone as the contact sensitizer uniquely formulated in a microemulsified drug delivery sytem consisting of the nonionic surfactant polyoxyethylene 20 sorbitan momooleate and the emollients isopropyl myristate and/or isopropyl palmitate. The immunmodulating compositions of this invention treat viral infections embodied by AIDS, Hepatitis B&C, other viral infectious diseases and certain types of cancer wherein the the patient's immune system is attacked by the disease. The active ingredients in these compositions are those that are classified pharmacologically as contact sensitizers such as dinitrochlorobenzene, dinitrofluorobenzene, diphenylcyclopropenone, oxazolone, paraphenylenediamine, squaric acid dibutylester, urushiol and the like that are generally recognized as pharmacologically active contact sensitizers. Topically applied, contact sensitizers have been shown to raise the CD4+ helper T cell counts and variably reduce viral load in HIV positive patients when applied as a concentrated solutions in Acetone as the vehicle (1,2,3).

Use of an amphipathic compound for providing an adjuvant to a subunit vaccine Inventor(s): Brunel; Florence (Genay, FR), Darbouret; Anne (Saint Maurice sur Dargoire, FR), Ronco; Jorge (La Mulatiere, FR) Assignee(s): Aventis Pasteur S.A. (FR) Patent Number: 6,472,159 Date filed: April 16, 2001 Abstract: The present invention provides a method of inducing an immune response to a subunit antigen in a non-responding subject by administering to the subject a composition comprising the subunit antigen and an amphipathic compound. A preferred antigen is a hepatitis B antigen, and a preferred amphipathic compound is DC-chol. Excerpt(s): The invention relates to the field of vaccine adjuvants. In particular, the invention relates to the use of an amphipathic compound for the manufacture of a vaccine composition intended for nonresponding subjects. It is known that, when a population of individuals is vaccinated against a disease, a number of them do not "respond" to the vaccination, that is to say that their immune system does not appear to react to the antigen administered. This problem is substantial to a greater or lesser degree depending on the diseases and the populations involved, but vaccine manufacturers are still trying to reduce, for each of the vaccines which they make available to doctors, the number of subjects likely to be "nonresponders". This problem is considered particularly for vaccines comprising purified antigens such as subunit vaccines produced by genetic engineering and in particular the hepatitis vaccine; however, while a number of amphipathic compounds, and in particular 3-.beta.-[N(N',N'-dimethylaminoethane)carbamoyl]cholesterol, commonly called DC-chol, are known which make it possible to increase the immune response in subjects who are already "responders", and are therefore considered to be good vaccine adjuvants, it is more difficult to find means of overcoming the problem of nonresponders, all the more so since all the reasons why an individual is a nonresponder have not yet been clearly identified. The research studies carried out in this field have shown that it was not possible to extrapolate the results obtained with adjuvants capable of increasing the immune response in "responding" subjects to the "nonresponding" subjects, given that

Patents 249

some good adjuvants in responding subjects are found to have no effect in nonresponding subjects. The aim of the invention is therefore to provide an improved vaccine as regards the level of seroconversion which it makes possible to obtain. For that, the invention proposes the use of an amphipathic compound for the preparation of a vaccine composition comprising at least one subunit antigen intended to be administered to target populations comprising individuals who are "nonresponders" to said antigen.

The 6methylnicotinamide derivatives of the present invention exhibit their inhibitory activity against the proliferation of human immunodeficiency virus (HIV) as well as hepatitis B virus (HBV) and Hepatitis C virus (HCV), such that they can be used for hepatitis B, hepatitis C and acquired immune deficiency syndrome (AIDS). Excerpt(s): R.sub.3 is 5-indazole or 6-indazole. Hepatitis B virus (HBV; referred as "HBV" hereinafter) causes acute or chronic hepatitis, which may progress to liver cirrhosis and liver cancer. It is estimated that three hundred million people are infected with HBV in the world (Tiollais & Buendia, Sci. Am., 264, 48, 1991). There has been much research about the molecular biological characteristics of HBV and their relationship to liver diseases in order to find ways to prevent and treat hepatitis B. Various vaccines and diagnostic drugs have been developed and much effort is being channeled into research to find treatment for hepatitis B. HBV genome consists of genes for polymerase (P), surface protein (pre-S1, pre-S2 and S), core protein (pre-C and C), and X protein. Of these proteins expressed from HBV genes, polymerase, surface protein, and core protein are structural proteins and X protein has a regulatory function.

Excerpt(s): This invention relates to arabinogalactans. In particular, this invention relates to an acid-modified arabinogalactan protein composition, having an arabinose:galactose ratio of less than 3.5:1 or less than 80% of the arabinose:galactose ratio of the arabinogalactan protein component of the composition prior to acid modification, prepared from Astragalus membranaceus, especially from the roots of Astragalus membranaceus. Huang-qi, Radix Astragali, is the dried root of Astragalus membranaceus Bge. var. mongholicus (Bge.) Hsiao or A. membranaceus (Fisch.) Bge. (Fabaceae). Huang-qi is a very old and well known drug in traditional Chinese medicine. It is officially listed in the Chinese Pharmacopoeia and used mainly as a tonic and for treatment of nephritis and diabetes. It is commonly used as a decoction or "tea" alone or with other plants in the traditional medicines Shi-ka-ron (a combination with herbs Lithosperium erythrorhizon and Ligusticum wallachii) and Ren-shen-yang-rongtang (a combination of twelve herbs including Radix Astragali) [The section entitled "Astragalus membranaceus (Fisch.) Bge.", Section 26, pages 191-197, of "Chinese Drugs of Plant Origin", W. Tang and G. Eisenbrand, eds., Springer Verlag, Berlin, 1992]. Huang-qi decoctions, and solutions prepared from the alcohol-precipitated decoction, have also been administered by injection, and are reported to give improvement in the symptoms of gastric and duodenal ulcers and increase the white blood cell count in chronic leukopenia [The section entitled "Huangqi", pages 1041-1046, of "Pharmacology and Applications of Chinese Materia Medica", H.-M. Chang and P. P.-H. But, eds., World Scientific Publishing Co., Singapore, 1987]. Huang-qi decoctions, purified low molecular weight fractions (e.g. 25,000-35,000 MW), and decoctions of herb mixtures containing huang-qi, have also shown activity in restoring the immune system in local xenogeneic graft-versus-host reaction [D.-T.

The invention further comprises pharmaceutical compositions comprising such compounds as well as methods of treating mammals, particularly humans, infected with HBV and other viral infections. Excerpt(s): The present invention is in the field of anti-viral agents, particularly antiviral L-nucleosides, and more particularly anti-viral 7-deaza L-nucleosides. Nucleoside and nucleotide analogs have long been studied as potential antiviral compounds. A number of D-nuceloside analogs are presently used as antiviral agents, including HIV reverse transcriptase inhibitors (such as AZT, ddI, ddC, and d4T). Similarly, purine Dnucleoside analogs have also been explored in search of immunomodulators. Guanosine analogs having substituents at the 7- and/or 8-positions, for example, have been shown to stimulate the immune system (for a review, see Weigle, W. O., CRC Crit Rev. Immunol. 7:285,1987; Lin et al., J. Med. Chem. 28:1194, 1985; Reitz et al., J. Med. Chem. 37:3561, 1994; Michael et al., J. Med. Chem. 36:3431,1993). 7-Deazaguanosine and analogs have been shown to exhibit antiviral activity in mice against a variety of RNA viruses, even though the compound lacks antiviral properties in cell culture. 3Deazaguanine nucleosides and nucleotides have also demonstrated significant broad spectrum antiviral activity against certain DNA and RNA viruses (Revanker et al., J. Med. Chem. 27:1389,1984). Certain 7- and 9-deazaguanine L-nucleosides exhibit the ability to protect mice against lethal challenge of Semliki Forest virus (Girgis et al., J. Med. Chem. 33:2750, 1990) (see also WO 98/16184, which discloses purine L-nuceloside analogs as antiviral agents). Web site: http://appft1.uspto.gov/netahtml/PTO/search-bool.html

Antiviral agent for drug-resistant virus Inventor(s): Kamiya, Naohiro; (Kawasaki-shi, JP), Omata, Masao; (Funabashi-shi, JP), Yuasa, Satoshi; (Kawasaki-shi, JP) Correspondence: Greenblum & Bernstein, P.L.C.; 1941 Roland Clarke Place; Reston; VA; 20191; US Patent Application Number: 20030109498 Date filed: October 29, 2001 Abstract: 2-amino-6-arylthiopurinephosphonate used in the antiviral agent of the present invention has no toxicity such as bone marrow cell growth inhibition or mutagenicity, and has a high antiviral activity, oral absorbency and safety. Furthermore, the compound of the present invention is effective for a mutant virus which is known to exhibit resistance to the conventional antiviral agents. Therefore, the present invention can provide a useful antiviral agent which leads to the establishment of a method for treating hepatitis B, which is a medically important object. Excerpt(s): The present invention relates to a method for treating a YMDD mutant virus disease which shows a drug-resistance against lamivudine ((-)-.beta.-L-2',3'-dideoxy-3'thiacytidine, which is referred to as 3TC) which is a conventional antiviral agent. More specifically, the present invention relates to a method for treating a virus disease which comprises administering a phosphonate nucleotide compound having the abovementioned antiviral activity, or a salt thereof, or a hydrate thereof or a solvate thereof. Among virus diseases, especially human immunodeficiency virus (HIV) infection (i.e., acquired immune deficiency syndrome (AIDS)) and hepatitis B virus (HBV) infection (i.e., hepatitis B) are considered to be a medically crucial problem because of the high absolute number of patients presented in the world. For the purpose of treating these diseases, various agents having an antiviral activity has been actively developed. Among such agents, lamivudine was developed as the first antiviral agent which inhibits the replication of both HIV and HBV, and it has already been approved as an agent for HIV infection in large number of countries. Lamivudine has recently been approved also for HBV infection in some countries, and there are many reports that lamivudine has clinically been used. The greatest problem regarding the treatment of HBV infection with lamivudine discussed in these reports is that an emergence of drugresistant viruses increases after the long term administration of lamivudine. It is known that these drug-resistant viruses, as is in the case of HIV, have the mutation of methionine residue in an amino acid sequence, tyrosine-methionine-aspartic acidaspartic acid (YMDD) motif located in an active center of a viral DNA polymerase. In the case of HIV, there has been reported a result of the X-ray crystallographic analysis of a YMDD mutant polymerase (Sarafianos, S. G. et al., Proc. Natl. Acad. Sci., USA 96, 10027-10032 (1999)). This result suggests a possibility that the substitution of methionine by isoleucine or valine interferes the binding of lamivudine triphosphate to an active center and a possibility of cross-resistance to other nucleoside derivatives having.beta.L-ring occurs. On the other hand, in the case of HBV, the single substitution of leucine by methionine (L528M) on the B domain of HBV polymerase identified by the clinical trial of Famciclovir (2-[2-(2-amino-9H-purin-9-yl)ethyl]-1,3-pro- panediol diacetate) against HBV infection shows a resistance to Famciclovir (Seigneres, B., et al., J. Infect. Dis., 181, 1221-1233 (2000)). It is suggested, however, that since a YMDD mutant HBV also having a L528M mutation acquires a higher ability to replicate viral DNA than HBV having a single YMDD mutation, and emerges as a cross drug-resistant HBV (Ono, S. K., et al., J. Clin. Invest., 107, 449-455 (2001)). Summarizing several reports, the emergence rate of a YMDD mutant virus in hepatitis B patients is 17 to 46% after the continuous

Patents 253

use of lamivudine for 1 year, and 65 to 75% after the use of lamivudine for 3 to 4 years (Ono, S. K., et al., J. Clin. Invest., 107, 449-455 (2001)). The emergence of a drug-resistant mutant virus reduces the efficacy of the agent. As a result, even if the administration of the agent is continued, proliferation of the virus occurs, resulting in the recurrence of hepatitis B. If the administration of the agent is stopped at this moment, a wild type of HBV having a higher replication ability than drug-resistant mutant virus proliferates again, resulting in the fear of the occurrence of fulminate hepatitis in some cases. However, since it is only lamivudine that has been approved as an antiviral agent against HBV, there is a therapeutic contradiction in that the patients is administered with lamivudine, even if lamivudine is ineffective, and this contradiction would cause some hesitation in administrating the agent to a new hepatitis B patient. The present inventors have already found that some of phosphonate nucloetide compounds show a high oral absorbency (EP632048), and have obtained an antiviral agent having anti-HBV activity without toxicity such as bone marrow cell growth inhibition or mutagenicity by changing the base portion of those compounds to a specific structure (EP785208). These compounds having a several ten-fold activity as compared with lamivudine, have been developed as novel agents for treating hepatitis B.

The variant HBVs are delivered to cells using a baculovirus vector. The same agents generally have a particular effect or absence of effect on a reference HBV. The altered sensitivity is in relation to the effects of the agent on one or more stages of infection, replication, assembly or release of virus or virus-like particles including any intermediary steps during the processes of viral infection, replication, assembly and/or release. The identification of variant HBVs with altered sensitivities to anti-HBV agents provides a means of monitoring cross resistance, or the development of new therapeutics effective against variant HBVs with altered sensitivities to other anti-HBV agents, as well as monitoring therapeutic protocols which may then need to be modified to ensure the appropriate anti-HBV agent is administered or that the appropriate therapeutic protocol is instituted. The present invention further provides variant HBVs detected by the assay of the present invention and to components thereof as well as recombinant, chemical analogue, homologue and derivative forms of such components.

Excerpt(s): This invention relates to the construction of chimaeric hepadnavirus core antigen proteins. Hepatitis B virus is a hepadnavirus virus with a partly double stranded genome of 3200 nucleotides. The viral DNA is surrounded by the viral coded core antigen (HBcAg) which is enclosed by the similarly coded surface antigen (Robinson, Ann. Rev. Microbiol. 31, 357-377, 1977). Removal of the surface antigen by mild detergent treatment leaves a core particle 27 nm in diameter composed of HBcAg and the viral DNA. HBcAg has been expressed in microbial cells as the native polypeptide and as a derivative fused to the terminal eight residues of betagalactosidase (see Murray et al, EMBO J. 3, 645-650, 1984 for refs). When synthesized in E. coli the core protein self assembles into 27 nm particles which can be visualized under the electron microscope (Cohen and Richmond, Nature, 296, 677-678, 1982) and which are immunogenic in laboratory animals (Stahl et al, Proc. Natl. Acad. Sci. USA 79, 16061610, 1982). The amino acid sequence of the core antigen shows a region towards the carboxy terminus which is homologous with that found in protamines (DNA binding proteins). By inference, it has been suggested that this part of the molecule interacts with DNA during assembly of core particles (Pasek et al, Nature, 282, 575-579, 1979).

This application claims priority to U.S. provisional patent application No. 60/106,664, filed on Nov. 2, 1998. HBV is second only to tobacco as a cause of human cancer. The mechanism by which HBV induces cancer is unknown, although it is postulated that it may directly trigger tumor development, or indirectly trigger tumor development through chronic inflammation, cirrhosis, and cell regeneration associated with the infection. Hepatitis B virus has reached epidemic levels worldwide. After a two to three month incubation period in which the host is unaware of the infection, HBV infection can lead to acute hepatitis and liver damage, that causes abdominal pain, jaundice, and elevated blood levels of certain enzymes. HBV can cause fulminant hepatitis, a rapidly progressive, often fatal form of the disease in which massive sections of the liver are destroyed.

In particular the present invention relates to combination vaccines for administration to adolescents. HSV-2 is the primary etiological agent of herpes genitalis. HSV-2 and HSV-1 (the causative agent of herpes labialis) are characterised by their ability to induce both acute diseases and to establish a latent infection, primarily in neuronal ganglia cells. Genital herpes is estimated to occur in about 5 million people in the U.S.A. alone with 500,000 clinical cases recorded every year (primary and recurrent infection). Primary infection typically occurs after puberty and is characterised by the localised appearance of painful skin lesions, which persist for a period of between 2 to 3 weeks. Within the following six months after primary infection 50% of patients will experience a recurrence of the disease. About 25% of

Compositions, including pharmaceutical compositions, of CTL-inducing peptide and an adjuvant or a lipidated peptide which induces a helper T cell (HTL) response stimulate the antigen specific CTL response. Among the viral antigens to which the CTL responses are effectively induced in humans are those of hepatitis B. The CTL response may be optimized by a regimen of two or more booster administrations. Cocktails of two or more CTL inducing peptides are employed to optimize epitope and/or MHC class I restricted coverage. Excerpt(s): The present application is a continuation of U.S. application Ser. No. 08/197,484, filed Feb. 16, 1994 which is a continuation-in-part of U.S. application Ser. No. 07/935,811, filed Aug. 26, 1992, which is a continuation-in-part of U.S. application Ser.

No. 07/749,568, filed Aug. 26, 1991 and now abandoned, each of which is incorporated herein by reference. Cytotoxic T lymphocytes ("CTL") represent an important component of an animal's immune response against a variety of pathogens and cancers. CTL which have been specifically activated against a particular antigen are capable of killing the cell that contains or expresses the antigen. CTL are particularly important in providing an effective immune response against intracellular pathogens, such as a wide variety of viruses, and some bacteria and parasites. CTL responses are also believed to be capable of contributing to anti-tumor responses in afflicted or susceptible individuals. The receptors on the surface of the CTL cannot recognize a foreign antigen directly, however. The CTL express an.alpha.-.beta.heterodimeric T cell receptor which is capable of recognizing foreign antigen fragments bound to major histocompatibility complex (MHC) class I molecules on the surface of the effected (e.g., infected) cells. CTL also express the non-polymorphic CD8 antigen. This cell surface protein interacts with the third domain of the class I molecule on the antigen presenting cells and plays a role in both stabilizing the interaction between the CTL and the antigen presenting cell and in CTL activation (Salter et al., Nature 345:41-46 (1990)).

The invention relates to new compositions and medical uses, such as anti-infectious pharmacology. The invention also relates to the development of new therapeutic agents based on active metabolites of peptides, nucleosides and nucleotides that are intended to be used for treatment and prevention of infectious diseases such as viral hepatitis B and C, AIDS and herpes. The function of pleiotropic cytokine, IL-12 can be a factor for host immune response regulation. By regulating the Th1/Th2 balance, IL-12 modulates macrophage functions, especially for liver resident macrophages (Kuppfer's cells). For chronic hepatitis C or B, IL-12 activates cytokine release in the Th1 cells, inhibiting corresponding Th2 function. Chronic forms and an unfavorable courses of viral hepatitis are accompanied with a decreased IL-12 content. (Schlaak, J. F. et al., J. Med. Virol. 1998, 56: 112-117.) Thus, T-cell immunity relating to the course and outcome of HBV and HCV infections and successful treatment is dependent on endogenous production of appropriate cytokines capable of responding to an antigen stimulus. The host immune response and production of these cytokines, which are in competition with the generation of new "quasi-species", both can determine the capability for modulating the targeting and intensity of the host immune response.

258 Hepatitis B

Abstract: Diketoacids of Formula A are useful as inhibitors of viral polymerases. In particular hepatitis C virus RNA dependent RNA polymerase (HCV RdRp), hepatitis B virus polymerase (HBV pol) and reverse transcriptase of human immunodeficiency virus (HIV RT): 1The group R may be broadly chosen and is an organic moiety which contains 2 to 24 carbon atoms and includes an optionally cyclic or heterocyclic group in which the atom directly bonded to the adjacent carbonyl in the diketoacid is part of the ring structure. Excerpt(s): The present invention relates to compounds useful as enzyme inhibitors, in particular as inhibitors of enzymes involved in the transfer of phosphoryl groups and, especially as inhibitors of polymerases. The invention further relates to pharmaceutical compositions containing such compounds, and to their use in the treatment of viral infections. Polymerases are the enzymes which catalyse the formation of phosphodiester bonds in RNA and DNA. They play an essential role in viral replication and, therefore, are an important target in the fight against viral diseases such as human immunodeficiency virus (HIV), hepatitis, and poliomyelitis. U.S. Pat. No. 5,475,109 describes dioxobutanoic acids substituted with piperidine or similar N-substituted saturated cycloalkyls as inhibitors of the cap-dependent endonuclease of influenza virus.

In treating hepatitis infections, the compounds of Formula I may be used alone, or in combination with another antiviral agent selected from among nucleosides, nucleotides, immunomodulators, immunostimulants or various combinations of such other agents. Excerpt(s): The present invention relates to methods and compositions for treating hepatitis virus infections, especially hepatitis B virus infections, in mammals, especially humans. The methods comprise administering glucamine compounds in combination with nucleoside antiviral agents, nucleotide antiviral agents, mixtures thereof, or immunomodulating/-immunostimulating agents. Such combinations of anti-hepatitis viral agents show unexpected efficacy in inhibiting replication and secretion of hepatitis viruses in cells of mammals infected with these viruses. Over half the biologically important proteins are glycosylated and that glycosylation may vary with disease. Based upon this information, the use of drugs to control of glycosylation patterns, glycoforms, changes or rates of change will have a a biochemical effect and may provide a beneficial therapeutic result. Control of glycolipid and glycoprotein sugar patterns as well as their synthesis and degradation leads to basic physiological effects on mammals including humans, agricultural animals and pets. Possibly, this is through influences on, for example, N-linked glycans, O-linked glycans, glucosoaminoglycans, glycosphingolipids, glycophospholipids, lectins, immuneoglobulin molecules,

Patents 259

antibodies, glycoproteins and their biochemical intermediates or conversion products. Modification of glycosalation site occupancy influences receptor and enzyme binding site specificity, selectivity, capacity, protein folding, enzyme activity, kinetics and energetics. Glycosidase and glycosyltransferase systems are two biochemical mechanisms that are suggested to affect such systems (Dwek, Raymond A., Glycobiology: Toward Understanding the Function of Sugars, Chemical Reviews, 96, 683-720(1996). Iminosugars are anti-viral drugs that can induce the inhibition of viral interactions with and within mammalian cells such as attachment to cells, penetration of cells, maturation within cells and release from cells. The mechanism involved may be glucosidase inhibition, glycosyl transferase inhibition or others as discussed above. Web site: http://appft1.uspto.gov/netahtml/PTO/search-bool.html •

HBV core antigen particles with multiple immunogenic components attached via peptide ligands Inventor(s): Murray, Kenneth; (Edinburgh, GB) Correspondence: Fish & Neave; 1251 Avenue OF The Americas; 50th Floor; New York; NY; 10020-1105; US Patent Application Number: 20030198649 Date filed: May 29, 2003 Abstract: This invention relates to hepatitis B virus ("HBV") core antigen particles that are characterized by multiple immunogen specificities. More particularly, the invention relates to HBV core antigen particles comprising immunogens, epitopes, or other related structures, crosslinked thereto by ligands which are HBV capsid-binding peptides that selectively bind to HBV core protein. Such particles may be used as delivery systems for a diverse range of immunogenic epitopes, including the HBV capsid-binding peptides, which advantageously also inhibit and interfere with HBV viral assembly by blocking the interaction between HBV core protein and HBV surface proteins. Mixtures of different immunogens and/or capsid-binding peptide ligands may be crosslinked to the same HBV core particle. Such resulting multicomponent or multivalent HBV core particles may be advantageously used in therapeutic and prophylactic vaccines and compositions, as well as in diagnostic compositions and methods using them. Excerpt(s): The front-line of clinical immunotherapeutic regimens includes patient immunizations against infectious pathogens and other health-threatening agents. Despite the plethora of immunization agents, inoculations may afford, at best, partial immunity, requiring frequent re-immunizations. Such is the case for various conventional monovalent or polyvalent vaccines. And even among such vaccines, the number of single agent inoculants capable of eliciting immunity against a variety of immunogens is limited. Furthermore, antigenic variation among pathogens may limit the efficacy of conventional vaccines. Due to such obstacles, efforts have focused on methodologies for enhancing the immune system response to given immunogens. To that end, immunogenic conjugates have been produced by linking immunogens to hepatitis B virus ("HBV") core particles (also referred to as nucleocapsids or nucleocapsid shells), in efforts to enhance the immunogenicity of the linked immunogen, through the operation of T cell dependent and T cell independent determinants of HBV core antigen. See, for example, U.S. Pat. No. 4,818,527 and R. Ulrich et al., "Core Particles of Hepatitis B Virus as Carrier for Foreign Epitopes", Adv. Virus. Res., 50, pp. 141-82 (1998). Enhanced immunogenicity of epitopes of interest has also been approached via hybrid viral particle-forming proteins, comprising at least a

portion of a naturally occurring viral particle forming protein, for example HBV surface antigen, and one or more epitopic sites of interest. See U.S. Pat. No. 5,965,140. As evident from such efforts, proteins of HBV have been used as platforms for presenting immunogens of interest to the immune system.

The present invention further relates to the use of these genes and their translation products to establish experimental models for HBV infection, whether in cell culture or in animals. The present invention further relates to the use of these genes and their translation products for therapeutic purposes. The present invention further relates to the use of these genes and their translation products to screen for additional binding protein interactions. The present invention further relates to the use of these genes and their translation products to prepare specific detectors of these proteins, including, but not limited to, antibodies, phage-display libraries, specific PCR primers, lectins, DNA probes, RNA probes, and non-antibody proteins for diagnostic and therapeutic purposes. Hepatitis B virus (HBV) is an enveloped RNA virus that infects human liver and replicates via reverse-transcription of the pregenomic RNA. Infected patients develop acute hepatitis, which is often selflimiting, but may develop into chronic hepatitis with high risk of liver cirrhosis and primary liver carcinoma in roughly 10% of all cases. The World Health Organization estimates that there will be 400 million carriers Worldwide in year 2000. Effective vaccines exist, but anti viral drugs with good and long term efficacy are not available.

Little is known about how HBV infects liver cells and the HBV cellular receptor(s) remain unknown. Many proteins have been identified which bind to the viral envelope associated proteins, HBsAg, or related proteins, but none are considered genuine HBV receptors (reviewed in De et al., 1997 and in references cited therein). Some of these binding proteins are found in serum and some in hepatocytes. None of these molecules have been convincingly tied to infectivity, disqualifying them as genuine HBV receptors. These molecules are of three types, S binding proteins, preS2 binding proteins, and preS1 binding proteins. A brief summary of the characteristics of the three groups is provided herein.

Humanized antibody to surface antigen s of hepatitis b virus and a preparing method thereof Inventor(s): Hong, Hyo-Jeong; (Taejeon-si, KR), Kim, Keun-Soo; (Kyunggi-do, KR) Correspondence: Gates & Cooper Llp; Howard Hughes Center; 6701 Center Drive West, Suite 1050; Los Angeles; CA; 90045; US Patent Application Number: 20030096403 Date filed: June 3, 2002 Abstract: The present invention relates to the humanized antibodies to surface antigen S of hepatitis B virus and a preparing method thereof. Particularly, it relates to the humanized antibodies which comprise heavy and light chains having amino acid sequences originated from human antibodies at the HCDR1, HCDR2, HCDR3 and LCDR1, LCDR2, LCDR3 of their variable regions, expression vectors containing each of the heavy and light chain genes of the humanized antibody and transformant which can produce humanized antibody by transfection with heavy and light chain expression vectors and a preparing method thereof. A humanized antibody of the present invention is more humanized than that of the previous arts. So, it minimizes the probability of immune response in humans and has good antigen binding capacity, making it a excellent candidate for prevention and treatment of the hepatitis B virus infection. Excerpt(s): Hepatitis B virus (HBV) invades into human body and causes chronic and acute hepatitis. If the condition grows worse, it can be a pathogen causing cirrhosis and cancer of the liver. It is estimated that up to three hundred millions patients in the world are infected with HBV (Tiollais & Buendia, Sci. Am., 264, 48, 1991). The envelope of HBV is composed of 3 types of proteins. Specifically, it is composed of major protein comprising S antigen, middle protein comprising S antigen and pre-S2 antigen, and large protein comprising S antigen, pre-S2 antigen and pre-S1 antigen (Neurath, A. R. and Kent, S. B. H., Adv. Vir. Res., 34: 65-142, 1988). All of the above-mentioned HBV surface antigen proteins can induce antibodies which neutralize HBV. Among them, S antigen takes part of about 80% of the total envelop protein and has neutralizing epitope called "Common a" which is commonly present in all of HBV subtypes. When infected with HBV, for example, in cases of new-born babies born from HBV positive mother or medical institution employees exposed to HBV or recipients undergoing liver transplantation from patient having HBV-related liver diseases, HB immune globulin (HBIG) has been used to prevent the HBV infection (Beasley et al., Lancet, 2, 1099, 1983; Todo et al., Hepatol., 13, 619, 1991). However, since the currently used HBIG is prepared from human plasma, it has the disadvantages that the specificity against antigen is low and the probability of contamination is relatively high. Moreover, human blood has to be continuously supplied. Web site: http://appft1.uspto.gov/netahtml/PTO/search-bool.html

Abstract: Hepatitis B virus capture oligonucleotides, primers and probes derived from conserved regions of the hepatitis B virus genome are disclosed. Also disclosed are nucleic acid-based assays using the capture oligonucleotides, primers and probes. Excerpt(s): This application is related to provisional patent applications serial No. 60/328,492 filed Oct. 9, 2001, serial No. 60/368,823 filed Mar. 29, 2002, and serial No. 60/393,561 filed Jul. 2, 2002, from which priority is claimed under 35 USC.sctn.119(e)(1) and which applications are incorporated herein by reference in their entireties. The present invention pertains generally to viral diagnostics. In particular, the invention relates to nucleic acid-based assays for accurately diagnosing hepatitis B infection. Hepatitis B virus (HBV) is a member of a group of small DNA-containing viruses that cause persistent noncytopathic infections of the liver. HBV infection in humans can cause severe jaundice, liver degeneration and death. HBV enters predominantly by the parenteral route, has a characteristic incubation period of 60 to 160 days, and may persist in the blood for years in chronic carriers. It is estimated that about 6 to 7% of the human population is infected, with the level of infection being as high as 20% of the population in certain regions of Southeast Asia and sub-Sahara Africa.

Method and device for the rapid clinical diagnosis of hepatitis B virus (HBV) infection in biological samples Inventor(s): Kondiboyina, Venkata Ramana; (Mumbai, IN), Sharma, Vijay; (Mumbai, IN) Correspondence: Lackenbach Siegel; One Chase Road; Scarsdale; NY; 10583; US Patent Application Number: 20030157478 Date filed: January 3, 2002 Abstract: There is provided a method and kit for rapid clinical diagnosis of HBV in which the amplimers are transcripts of a pre-core or envelop region gene of HBV. The amplicons are hybridized to a specific oligonucleotide probe, which allows the amplicons to be detected. Excerpt(s): The present invention relates to methods and devices for the diagnosis of infections. In particular, the present invention relates to methods and kits for detection of Hepatitis B Virus Viremia (HBV). Hepatitis B virus (HBV) is an enveloped hepatotropic DNA virus. Acute and chronic HBV infection causes significant liver diseases and it is estimated that more than 300 million individuals world wide are chronically infected with HBV. The HBV genome is unique in the world of viruses due to its compact nature, use of overlapping reading frames, and dependence on a reversetranscriptional step, though the virion contains primarily DNA. The human hepatitis B virus is a member of the Hepadna Viridae family which includes duck hepatitis virus (DHBV), Ground squirrel hepatitis virus (GSHV), snow goose hepatitis B virus (sgHBV), woodchuck hepatitis virus (WHV) and wooly monkey hepatitis virus. Furthermore, persistent viral infection leads to chronic active hepatitis, liver cirrhosis and the development of hepatocellular carcinoma. It has recently been appreciated that individuals who recover from HBV infection have a broad based cellular immune response to HBV structural proteins. Indeed, cytotoxic lymphocyte activity (CTL) may be critical for promoting viral clearance from the liver and CTL activity has been detected many years after resolution of acute infection. The presence of CTL activity may be due to persistence of low level HBV infection in the liver that can be identified only by molecular techniques such as PCR. Thus, the concept has arisen that even if individuals serologically recover from HBV infection, the virus, in most instances is never completely irradicated from the liver. Hepatitis B is of great medical importance because Hepatocellular carcinomas(HCC), one of the most common cancers afflicting humans, is primarily caused by chronic HBV infection. In the last few decades, the correlation between HBV and the development of HCC has been well established. However, the mechanism by which HBV transforms hepatocytes remains elusive. It is noticed that before HBV can transform a cell, the virus first infects it. However, the mechanism through which HBV enters hepatocyte has not been resolved despite further understanding of the viral protein involved. Much more research is needed before it is fully understood by the scientist and the spread of this infectious agent is controlled. Web site: http://appft1.uspto.gov/netahtml/PTO/search-bool.html

Method and kit for detecting hepatitis B virus Inventor(s): Lee, Tzong Hae; (San Francisco, CA) Correspondence: Stevens, Davis, Miller & Mosher, L.L.P.; 1615 L Street, N.W., Suite 850; P.O. Box 34387; Washington; DC; 20036; US Patent Application Number: 20030215790 Date filed: May 20, 2002 Abstract: A method for detecting Hepatitis B virus (HBV) in a sample includes the steps of (a) adding to the sample a thermostable polymerase, appropriate nucleoside triphosphates, a nucleic-acid-binding fluorescent entity, and a pair of primers substantially complementary to a target nucleic acid having the sequence shown in SEQ ID NO:1 or the complement of the target nucleic acid; (b) thermally cycling the sample between at least a denaturation temperature and an elongation temperature; (c) illuminating the sample with a selected wavelength of light that is absorbed by the fluorescent entity during the thermally cycling step; (d) determining the amount of fluorescence generated by the fluorescent entity; and (e) detecting the presence of the target nucleic acid by analyzing the amount of luminescence determined after at least one amplification cycle. The invention further provides kits for detection of HBV in samples. Excerpt(s): This invention relates to a method for detecting or quantifying Hepatitis B virus (HBV) in a sample. The disease known as hepatitis B is caused by the infectious Hepatitis B virus (HBV). It has been estimated by the World Health Organization (WHO) that HBV have infected over two billion people worldwide. This makes HBV one of the most common human pathogens. Approximately 500 million are chronic carriers. Hepatocellular carcinomas (HCC), one of the most common cancers afflicting humans, is primarily caused by chronic HBV infection. Transmission of HBV is primarily through blood and/or sexual contact, though other methods of transmission have been suggested. Before HBV can transform a cell, the virus must first infect it. However, the mechanism through which HBV enters hepatocytes has not been resolved despite further understanding of the viral proteins involved. Vaccines are available against HBV, but they may not be 100% effective against all variants of HBV. Furthermore, there is no cure for individuals already infected. Much more research is needed before we fully understand and control the spread of HBV. Currently, a sensitive, specific and rapid assay to detect HBV DNA is not available. Traditional PCR methods have been utilized in humans to measure viral load for diagnosis of hepatitis B. However, traditional PCR methods do not allow accurate quantitation as the product is monitored beyond the exponential phase of PCR reaction and require laborious postPCR processing. Moreover, methods such as southern blot analysis are not sensitive or quantitative enough to reliably monitor decrease in viral reduction during antiviral therapy. Accordingly, there exists a need in the art for a rapid and sensitive method for detecting or quantifying HBV in a sample. Web site: http://appft1.uspto.gov/netahtml/PTO/search-bool.html

Box 8097; Emeryville; CA; 94662; US Patent Application Number: 20030162167 Date filed: July 25, 1996 Abstract: A family of cDNA sequences derived from hepatitis C virus (HCV) are provided. These sequences encode antigens which react immunologically with antibodies present in individuals with non-A non-B hepatitis (NANBH), but which are absent from individuals infected with hepatitis A virus, or hepatitis B virus, and also are absent in control individuals. The HCV cDNA sequences lack substantial homology to the sequences of hepatitis delta virus (HDV) and HBV. A comparison of the sequences of amino acids encoded in the HCV cDNA with the sequences of Flaviviruses indicates that HCV may be related to the Flaviviruses.The HCV cDNA sequences and the polypeptides encoded therein are useful as reagents for the detection and therapy of HCV. The reagents provided in the invention are also useful for the isolation of NANBH agent(s), for the propagation of these agents in tissue culture, and for the screening of antiviral agents for HCV.

In a preferred embodiment, the nucleoside is L-FMAU, or a pharmaceutically acceptable salt or prodrug thereof. Excerpt(s): This application claims priority to U.S. Ser. No. 60/193,135, filed on Mar. 29, 2000. This invention is in the area of methods and compositions for the treatment of a host infected with hepatitis delta virus (also referred to as "HDV") that includes

administering an effective amount of a compound, in particular a nucleoside or nucleoside analog, that substantially reduces the level of hepatitis B surface antigen. In one nonlimiting embodiment, the nucleoside analog is 2'-fluoro-5-methyl-.beta.-Larabinof- uranosyl-uridine (also referred to as "L-FMAU") or a pharmaceutically acceptable salt or prodrug thereof. Type D hepatitis, the most severe form of viral hepatitis, is caused by infection with hepatitis D (delta) virus (HDV), a sub-viral satellite of hepatitis B virus (HBV) (Smedile, A., et al. (1994) Prog Liver Dis 12, 157-75). Compared with other agents of viral hepatitis, acute HDV infection is more often associated with fulminant hepatitis, a rapidly progressive, often fatal form of the disease in which massive amounts of the liver are destroyed. Chronic type D hepatitis is typically characterized by necroinflammatory lesions, similar to chronic HBV infection, but is more severe, and frequently progresses rapidly to cirrhosis and liver failure, accounting for the disproportionate association of chronic HDV infection with terminal liver disease (Smedile, A., et al. (1994) Prog Liver Dis 12, 157-75; Rizzetto, M., et al. (1983) Ann Intern Med 98, 437-41). Although HDV infection affects fewer individuals than HBV alone, the resulting acute or chronic liver failure is a common indication for liver transplantation in Europe as well as North America (Smedile, A. & Rizzetto, M. (1992) Int J Clin Lab Res 22, 211-215; Wright, T. L. & Pereira, B. (1995) Liver Transplant Surgery 1, 30-42). Chronic disease affects 15 million persons worldwide, about 70,000 of whom are in the U.S. The Centers for Disease Control estimates 1,000 deaths annually in the U.S. due to HDV infection (Alter, M. J. & Hadler, S. C. (1993) Prog Clin Biol Res 382, 243-50; Alter, M. J. & Mast, E. E. (1994) Gastroenterol Clin North Am 23, 437-55). Web site: http://appft1.uspto.gov/netahtml/PTO/search-bool.html •

Methods and reagents for the inhibition of hepatitis B virus replication Inventor(s): McSwiggen, James; (Boulder, CO), Morrissey, David; (Boulder, CO) Correspondence: Mcdonnell Boehnen Hulbert & Berghoff; 300 South Wacker Drive; Suite 3200; Chicago; IL; 60606; US Patent Application Number: 20030148985 Date filed: December 5, 2002 Abstract: The present invention relates to nucleic acid molecules that modulate Hepatitis B virus (HBV) gene expression and HBV replication, and methods thereof. Specifically, the present invention relates to nucleic acid decoy molecules and aptamers that bind to HBV reverse transcriptase and/or HBV reverse transcriptase primer sequences and methods for their use alone or in combination with other therapies. The present invention also relates to nucleic acid molecules that specifically bind the Enhancer I region of HBV DNA and methods for their use. Excerpt(s): The present invention concerns compounds, compositions, and methods for the study, diagnosis, and treatment of degenerative and disease states related to hepatitis B virus (HBV) infection, replication and gene expression. Specifically, the invention relates to nucleic acid molecules used to modulate expression of HBV. The following is a discussion of studies relating to hepatitis B virus (HBV). The discussion is not meant to be complete and is provided only for understanding of the invention that follows. The summary is not an admission that any of the work described below is prior art to the claimed invention. Chronic hepatitis B is caused by an enveloped virus, commonly known as the hepatitis B virus or HBV. HBV is transmitted via infected blood or other body fluids, especially saliva and semen, during delivery, sexual activity, or sharing of needles contaminated by infected blood. Individuals may be "carriers" and

Patents 269

transmit the infection to others without ever having experienced symptoms of the disease. Persons at highest risk are those with multiple sex partners, those with a history of sexually transmitted diseases, parenteral drug users, infants born to infected mothers, "close" contacts or sexual partners of infected persons, and healthcare personnel or other service employees who have contact with blood. Transmission is also possible via tattooing, ear or body piercing, and acupuncture; the virus is also stable on razors, toothbrushes, baby bottles, eating utensils, and some hospital equipment such as respirators, scopes and instruments. There is no evidence that HBsAg positive food handlers pose a health risk in an occupational setting, nor should they be excluded from work. Hepatitis B has never been documented as being a food-borne disease. The average incubation period is 60 to 90 days, with a range of 45 to 180; the number of days appears to be related to the amount of virus to which the person was exposed. However, determining the length of incubation is difficult, since onset of symptoms is insidious. Approximately 50% of patients develop symptoms of acute hepatitis that last from 1 to 4 weeks. Two percent or less of these individuals develop fulminant hepatitis resulting in liver failure and death. Web site: http://appft1.uspto.gov/netahtml/PTO/search-bool.html •

O. Box 1539; King OF Prussia; PA; 19406-0939; US Patent Application Number: 20030180316 Date filed: March 26, 2003 Abstract: A multi-valent vaccine composition is described comprising a conjugate of the capsular polysaccharide of H. influenzae b not adsorbed onto an aluminium adjuvant salt, and two or more further bacterial polysaccharides. A multi-valent vaccine composition is also described comprising a whole-cell pertussis component, tetanus toxoid, diphtheria toxoid, Hepatitis B surface antigen, a conjugate of the capsular polysaccharide of H. influenzae b, and a conjugate of a capsular polysaccharide of N. meningitidis type A or C (or both). Furthermore, a multi-valent vaccine composition is described comprising a whole-cell pertussis component, tetanus toxoid, diphtheria toxoid, and a low dose of a conjugate of the capsular polysaccharide of H. influenzae b. Excerpt(s): The present invention relates to new combination vaccine formulations. Combination vaccines (which provide protection against multiple pathogens) are very desirable in order to minimise the number of immunisations required to confer protection against multiple pathogens, to lower administration costs, and to increase acceptance and coverage rates. The well-documented phenomenon of antigenic competition (or interference) complicates the development of multi-component vaccines. Antigenic interference refers to the observation that administering multiple antigens often results in a diminished response to certain antigens relative to the immune response observed when such antigens are administered individually. Combination vaccines are known which can prevent Bordetella pertussis, Clostridium tetani, Corynebacterium diphtheriae, and optionally Hepatitis B virus and/or Haemophilus influenzae type b (see, for instance, WO 93/24148 and WO 97/00697). The present invention concerns the manufacture of the most ambitious multi-valent vaccines to date, the administration of which can prevent or treat infection by Bordetella pertussis, Clostridium tetani, Corynebacterium diphtheriae, Hepatitis B virus, Haemophilus influenzae and N. meningitidis, and preferably also Hepatitis A virus and/or Polio virus, wherein the components of the vaccine do not significantly interfere with the immunological performance of any one component of the vaccine.

Abstract: The invention concerns an isolated mHBV having the following characteristics: (i) a genome with partly double-strand circular DNA, (ii) the genome including the PreS, S, C, P and X genes, (iii) the Pre-S genes coding for surface antigens, the S gene coding for a HBsAg envelope protein, the C gene coding for a HBeAg protein and aHBcAg protein, the P gene coding for a DNA reverse polymerase/transcriptase enzyme and the X gene coding for a HBxAg protein. The invention is characterised in that the gene S comprises a DNA nucleotide sequence referenced SEQ ID NO 1 and the Pre-S gene comprises a nucleotide sequence referenced SED ID NO 3. The invention also concerns DNA molecule, RNA molecule, modified surface proteins and their uses in particular for diagnostic, therapeutic and vaccine purposes. Excerpt(s): Five types of viral hepatitis--hepatitis A, B, C, D, E--are now quite well known. In each case the virus invades the liver and provokes an inflammatory state with destruction of the hepatic cells. Hepatitis B is caused by a virus, the human hepatitis B virus (HBV). The HBV virus was discovered by Blumberg et al.: A "new" antigen in leukemia sera, JAMA 191: 541, (1965). The virus is transmitted in the blood, by sexual contact or by perinatal transmission. In most cases infection by HBV does not lead to any symptoms and is responsible for asymptomatic acute hepatitis. Acute hepatitis is characterized by digestive disorders, abdominal pains, coloration of the urine and abnormal, discoloured faeces, asthenia and jaundice. Acute hepatitis can develop into a fulminant form with rapid liver necrosis. Web site: http://appft1.uspto.gov/netahtml/PTO/search-bool.html •

Non-viral vesicle vector for cardiac specific gene delivery Inventor(s): Chien, Kenneth; (La Jolla, CA), Hoshijima, Masahiko; (La Jolla, CA) Correspondence: Brown, Martin, Haller & Mcclain Llp; 1660 Union Street; San Diego; CA; 92101-2926; US Patent Application Number: 20030166593 Date filed: April 30, 2002 Abstract: The invention is a non-viral vesicle vector for the delivery of nucleic acid to various cardiac cell types. The vesicle vector contains the hepatitis B envelope protein wherein at least part of the liver targeting sequence is deleted and replaced with a specific cardiac cell targeting sequence. The targeting sequence may be derived from viruses that have the natural tropism desired (e.g. adenovirus type 5 knob protein for cardiomyocyte delivery) or mammalian sequences (e.g. endothelin-1 for vascular endothelial cell delivery). The vesicle vector contains an expression construct for the expression of therapeutic genes in cardiac tissues. Excerpt(s): This application claims the benefit of priority of U.S. provisional application Serial No. 60/287,423 filed Apr. 30, 2001 which is incorporated herein by reference in its entirety. A sequence listing is submitted herewith under 35 C.F.R.sctn.1.821 and is incorporated herein by reference. The utility of gene delivery vectors for gene therapy is limited by the nonselective nature in which the vectors, either non-viral or viral, interact with the cell surface, resulting in transduction of numerous cell types in addition to the target cells. Much effort has been devoted to understand the mechanisms of viral targeting to different cell types. The information derived from these studies is now being exploited to select viruses that have the desired natural tropism or to modify viral targeting signals to redirect viruses to the cell type of choice.

Novel hepatitis B virus Inventor(s): Zheng, Jian; (Raritan, NJ) Correspondence: Audley A. Ciamporcero JR.; Johnson & Johnson; One Johnson & Johnson Plaza; New Brunswick; NJ; 08933-7003; US Patent Application Number: 20030165816 Date filed: March 30, 2001 Abstract: We isolated and characterized a new surface mutant of the hepatitis B virus surface antigen (HBsAg). The mutant was isolated from a symptomatic patient with Down's syndrome who was found to be persistently positive for both for HBsAg and anti-HBs Antibody (Ab) with an equally long-lasting anti-HB core (c) IgM Ab Excerpt(s): Hepatitis B virus (HBV), a small double stranded DNA virus, can cause a wide spectrum of clinical presentations: asymptomatic carrier state, acute self-limited hepatitis, fulminant hepatitis, and chronic liver diseases including chronic hepatitis, liver cirrhosis, and hepatocellular carcinoma. It has a circular genome of 3182 to 3221 base pairs (bp). Four major subtypes have been identified and can be differentiated by antibodies that recognize the different epitopes on the HBV surface. The HBsAg particles carry the common determinant, "a", as well as d or y and w or r subtype determinants, and are classified into the four major subtypes, i.e., adw, adr, ayw and ayr. Rare sera contain HBsAg particles with all four-subtype determinants (adywr). The antigenic determinants for the main HBV subtypes: adw, adr, ayw and ayr lie in the surface or "S" polypeptide. Two amino acid residues in particular, encoded by the S gene at codon positions 122 and 160, have been postulated to determine the different antigenic subtypes. While, the preC regions have frequently been reported to have mutations rendering HBe Ag negative. The virus has a high rate of mutation relative to other DNA viruses due to its mode of replication by reverse transcriptase of its pregenomic RNA. The importance of a novel mutant can be reflected in vaccine escape and HBsAg detection failure, implicating a public health problem. We have identified and characterized a new surface mutant of HBV. The mutant was isolated from a symptomatic patient with Down's syndrome who was found to be persistently positive for both for HBsAg and anti-HBs Antibody (Ab) with an equally long-lasting anti-HB core (c) IgM Ab. With a panel of six monoclonal antibodies (mAb(s)) to HBsAg, we evaluated the mutation influence on the major epitope of the "a" determinant antigenicity. A sample was taken from a 43-year-old white male patient with Down's syndrome who presented with jaundice to the American University of Beirut Medical Center in March 1999. The patient had no history of immunization to HBV, no transmissible risk factor including blood transfusion, IV drugs, homosexuality, family HBV infection or hemodialysis. During investigation, he was found to have elevated liver function tests (LFT): ALT 450 IU/L (range 10-35 IU/L), AST 250 IU/L (range 10-40 IU/L), gamma-GT 383 IU/L (range 10-50 IU/L), Bilirubin was 3.8/2.6 mg/dL (total/direct) (range, total: 0.1-1.2 IU/L and direct: 0.0-0.2 IU/L). More significantly, we noted incongruity in the HBV blood tests. The HBV markers test results using enzyme immunoassay (EIA) methodology were as follows: HBs Ag positive (>2/0.051), anti-HBs Ab positive (0.417/0.206), anti-HBc IgM Ab low positive (0.371/0.208), anti-HBc IgG Ab strong positive (>2/0.412), HBe Ag negative and anti-HBe Ab positive (0.197/0.830, a competitive assay). Both the anti-hepatitis A Ab and the anti-hepatitis C Ab were negative. Due to the discrepancy in the HBV markers, molecular methods were used to confirm the HBV antigen.

Nucleotide sequence analysis revealed that the overall structure of the cellular gene, which has been named hap, is similar to that of the DNA-binding hormone receptors. Six out of seven hepatoma and hepatoma-derived cell-lines express a 2.5 kb hap mRNA species which is undetectable in normal adult and fetal livers, but present in all non-hepatic tissues analyzed. Low stringency hybridization experiments revealed the existence of hap related genes in the human genome. The cloned DNA sequence is useful in the preparation of pure hap protein and as a probe in the detection and isolation of complementary DNA and RNA sequences. The hap protein is a retinoic acid (RA) receptor identified as RAR-.beta. Excerpt(s): This application is a continuation-in-part of application Ser.

274 Hepatitis B

Abstract: The invention provides compounds capable of treating against hepatitis infections, particularly hepatitis B viral infections. Compounds of the invention are nucleic acid-based and preferably comprise 2, 3, 4, 5 or 6 nucleoside units. Excerpt(s): This application claims the benefit of U.S. provisional application no. 601291,471, filed May 16, 2001. The present invention relates to nucleic-acid based compounds. Compounds of the invention are useful for a variety of therapeutic applications, including treatment against hepatitis B virus. Hepatitis B virus (HBV) is a compact, enveloped DNA virus belonging to the Hepadnavirus family. The virus is a major cause of chronic liver disease and hepatocellular carcinoma worldwide (Hoofnagle (1990) N. Eng. J Med., 323:337-339). HBV is associated with acute and chronic hepatitis and hepatocellular carcinoma and may be a cofactor in the development of acquired immune deficiency syndrome (Dinestag et al. in Harrison's Principles of Internal Medicine, 13th Ed. (Isselbacher et al. eds.) McGrw-Hill, NY, N.Y. (1993) pp. 1458-1483). At least 400 million people are currently infected with HBV. Web site: http://appft1.uspto.gov/netahtml/PTO/search-bool.html •

In particular, substantially purified oligonucleotide primers and probes are described that can be used for qualitatively and quantitatively detecting HBV nucleic acid in a test sample by amplification methods. The present invention also provides primers and probes for generating and detecting control nucleic acid sequences that provide a convenient method for assessing internal quality control of the HBV assay. Excerpt(s): The present invention relates generally to compositions and methods for detecting hepatitis B viral nucleic acids in a test sample. The following discussion of the background of the invention is merely provided to aid the reader in understanding the invention and is not admitted to describe or constitute prior art to the present invention. One of the major causes of hepatitis are specific hepatitis viruses. There are at least six different viruses responsible for various types of hepatitis. Among them, hepatitis B virus (HBV) is the most thoroughly characterized and complex etiologic agent. The infective Dane particle consists of a viral core plus an outer surface coat. The core contains circular double-stranded DNA and DNA polymerase, and it replicated within the nuclei of infected hepatocytes. Surface coat is added in the cytoplasm and is produced in great excess; it can be detected in serum by immunologic means as hepatitis B surface antigen (HBsAg).

Oral DNA composition for hepatitis B virus chronic infection Inventor(s): Ng, Mun-Hon; (Bagulo Villa, HK), Yuen, Kwok-Yung; (Baguio Villa, HK), Zheng, Bo-Jian; (Pokfulam Garden, HK) Correspondence: Sughrue Mion, Pllc; Suite 800; 2100 Pennsylvania AVE., N.W.; Washington; DC; 20037-3213; US Patent Application Number: 20030162741 Date filed: February 28, 2003 Abstract: The present invention provides an oral DNA composition for improving an impaired immunity associated with chronic infection of hepatitis B virus (HBV) and for suppressing transgene expression for a protrated period of time comprising an attenuated strain of bacterial cells which preferentially target phagocytic cells of the intestinal mucosa, and which serve as a vehicle for a plasmid vector carrying one or more genes or complementary DNA coding for at least a portion of a hepatitis B viral protein or peptide. Given orally, the DNA composition causes a transient and selflimiting infection of the intestinal tract through autolysis of the bacterial cells and release of the plasmid after gaining entry into infected host cells. A promotor contained within the plasmid allows for expression of the HBV gene(s) in the eurokaryotic environment, the viral products of which help to booster a cell-mediated immunity to clear the infection and reverse a state of immune tolerance characteristic of HBV chronic infection. Excerpt(s): The present invention relates to an oral DNA composition (ODV) for ameliorating an impaired immunity in individuals who are chronically infected with hepatitis B virus (HBV). The oral DNA composition serves to booster immunity against HBV, improve the immune deficits associated with the disease and clear the infection. The World Health Organization (WHO) estimated that there are 350 million people world wide, who are chronically infected with the hepatitis B virus (HBV) [1]. These individuals have a high risk of developing liver cirrhosis and liver cancer. In addition, being the only significant reservoir for HBV, these individuals also pose as a significant public health hazard. None of the treatments presently available for chronic HBV infection can clear the virus from these individuals and are only moderately effective in reducing virus replication [2-5]. The idea that HBV infection may be cleared through immune intervention is based on findings that acute self-limited HBV infection evokes vigorous, polyclonal T helper cell (Th) and cytotoxic T lymphocyte (CTL) responses against viral capsid and envelope antigens, leading to the clearance of the virus from the body. On the other hand, chronic HBV infection is associated with weak Th responses of a restricted spectrum of antiviral specificity and usually undetectable virus-specific CTL activity [6]. These findings suggested that an intact cell mediated immunity is the chief determinant of virus clearance and provided the rational basis for immune intervention of chronic HBV infection with the view to booster cell mediated immunity (CMI) against the virus in order to clear the infection [7]. The contention was further supported by findings from bone marrow transplantation showing that adoptive transfer of bone marrow cells from donors, who had acquired intact immunity against the virus from natural infection, can improve the immune deficits of the chronically infected recipients and thereby clear the infection [8].

Peptides for inducing cytotoxic T lymphocyte responses to hepatitis B virus Inventor(s): Chisari, Francis V.; (Del Mar, CA) Correspondence: Townsend And Townsend And Crew, Llp; Two Embarcadero Center; Eighth Floor; San Francisco; CA; 94111-3834; US Patent Application Number: 20030171538 Date filed: February 5, 2003 Abstract: Peptides are used to define epitopes that stimulate HLA-restricted cytotoxic T lymphocyte activity against hepatitis B virus antigens. The peptides are derived from regions of HBV polymerase, and are particularly useful in treating or preventing HBV infection, including methods for stimulating the immune response of chronically infected individuals to respond to HBV antigens. Excerpt(s): The present application is a continuation-in-part application of U.S. Ser. No. 08/100,870, filed Aug. 2, 1993, which is a continuation-in-part of U.S. Ser. No. 07/935,898, which is a continuation-in-part of U.S. Ser. No. 07/749,540, the disclosures of which are incorporated herein by reference. Cytotoxic T lymphocytes (CTLs) play an essential role in fighting cells infected with viruses, intracellular bacteria and parasites, and tumor cells. They do so by direct cytotoxicity and by providing specific and nonspecific help to other immunocytes such as macrophages, B cells, and other T cells. Infected cells or tumor cells process antigen through intracellular events involving proteases. The processed antigen is presented on the cellular surface in the form of peptides bound to HLA class I molecules to T cell receptors on CTLs. MHC class I molecules can also bind exogenous peptides and present them to CTLs without intracellular processing. At the present time it is difficult to accurately predict from the sequence of an antigenic protein how the protein will be processed and which peptide portions will bind HLA class I molecules and be presented to CTLs. Binding motifs have been predicted for some HLA class I molecules based on sequence analysis of peptides eluted from these molecules (Falk et al., Nature 351:290 (1991)). Further, of the peptides that are processed and do bind to HLA class I, which ones will contain CTLrecognizable epitopes is not yet predictable.

A method of making the improved rHBsAg is also provided. The improved HBsAg is used to provide vaccines with lower amounts of active ingredient, vaccines with higher immunogenicity and combination vaccines which produce and protective immunization against infection by hepatitis B virus and other infectious agents. Excerpt(s): The invention relates to recombinant hepatitis B surface antigen (rHBsAg), prophylactic and therapeutic vaccines containing HBsAg and methods of preparing HBsAg and vaccines. Over the past two decades, recombinant hepatitis B surface antigen expressed as the S form in yeast cells (rHBsAg) has superseded plasma-derived antigen as a vaccine against hepatitis B infection (Valenzuela et al., 1982; McAleer et al., 1984). In the plasma of infected animals, the surface antigen protein assembles into 22 nm particles comprising lipids and HBsAg. However, the assembly of the yeast produced rHBsAg into these virus-like particles has remained poorly understood. It has been established that reduction of the disulfide bonds in HBsAg abolishes or greatly decreases both its antigenic and immunogenic properties (Reviewed by Tiollais et al., 1981, Guesser et al., 1988; Mishiro et al., 1980; Chen et al, 1996; Hauser, et al 1988). For example, eleven out of the total 14 cysteine residues are conserved among three different type of S protein of Hepatitis B viruses, namely, HBsAg of human, woodchuck, and ground squirrel viruses. However, these three types of S protein share only medium to low overall sequence homology among (Stirk et al, 1992). Interestingly, all 8 cysteine residues in the"a" determinant loop (62 aa between predicted Helix B and Helix C) are fully conserved. This indicates that disulfide bonds may have an important role in maintaining the structural integrity of the antigenic determinants or epitopes (Stirk et al., 1992).

The vaccine comprises an immunogenic amount of chimeric, carboxy-terminal truncated hepatitis B virus nucleocapsid (core) protein (HBc) that is engineered for both enhanced stability of self-assembled particles and the substantial absence of nucleic acid binding by those particles. The chimeric protein molecule can include one or more immunogenic epitopes peptide-bonded to one or more of the N-terminus, the immunogenic loop or the Cterminus of HBc. The enhanced stability of self-assembled particles is obtained by the presence of at least one heterologous cysteine residue near one or both of the aminoterminus and carboxy-terminus of the chimer molecule.

Use of recombinant hepatitis B core particles to develop vaccines against infectious pathogens and malignancies Inventor(s): Birkett, Ashley J.; (Escondido, CA), Zavala, Fidel; (New York, NY) Correspondence: Darby & Darby P.C.; P. O. Box 5257; New York; NY; 10150-5257; US Patent Application Number: 20030185854 Date filed: February 7, 2003 Abstract: The present invention relates to methods and compositions for augmenting CD8+ T cell responses to an antigen in a mammal, comprising the use of recombinant hepatitis B core particles (rHEP) to present said antigen. The invention further relates to a method of boosting the rHEP particle-induced CD8+ T cell responses using secondary immunization with a recombinant vaccinia virus expressing the same antigen (rVAC). The methods and compositions of the present invention can be useful for prophylaxis and treatment of various infectious and neoplastic diseases. Excerpt(s): The successful elimination of pathogens, neoplastic cells, or self-reactive immune mechanisms following prophylactic or therapeutic immunization depends to a large extent on the ability of the host's immune system to become activated in response to the immunization and mount an effective response, preferably with minimal injury to healthy tissue. The rational design of vaccines initially involves identification of immunological correlates of protection--the immune effector mechanism(s) responsible for protection against disease--and the subsequent selection of an antigen that is able to elicit the desired adaptive response. Once this appropriate antigen has been identified, it is essential to deliver it effectively to the host's immune system. New vaccines are presently under development and in testing for the control of various infectious and neoplastic diseases. In contrast to older vaccines which were typically based on liveattenuated or non-replicating inactivated pathogens, modern vaccines are composed of synthetic, recombinant, or highly purified subunit antigens (e.g., recombinant or synthetic polypeptides, nucleic acids, or recombinant bacterial or viral vectors capable of inducing antibodies as well as T cell responses [see, e.g., Liljeqvist and Sthal, J. Biotech, 73:1-33, 1999]). Subunit vaccines are designed to include only the antigens required for protective immunization and are believed to be safer than whole-inactivated or liveattenuated vaccines. However, the purity of the subunit antigens and the absence of the

self-adjuvanting immunomodulatory components associated with attenuated or killed vaccines often result in weaker immunogenicity. Web site: http://appft1.uspto.gov/netahtml/PTO/search-bool.html •

Use of substituted-1,5-dideoxy-1,5-imino-D-glucitol compounds for treating hepatitis virus infections Inventor(s): Bryant, Martin L.; (Carlisle, MA), Mueller, Richard A.; (Glencoe, IL), Partis, Richard A.; (Evanston, IL) Correspondence: Senniger Powers Leavitt And Roedel; One Metropolitan Square; 16th Floor; ST Louis; MO; 63102; US Patent Application Number: 20030220299 Date filed: January 14, 2003 Abstract: N-Substituted-1,5-dideoxy-1,5-imino-D-glucitol compounds of Formula I are effective in treatment of hepatitis infections, including hepatitis B and hepatitis C. In treating hepatitis infections, the compounds of Formula I may be used alone, or in combination with another antiviral agent selected from among nucleosides, nucleotides, immunomodulators, immunostimulants or various combinations of such other agents. Excerpt(s): The present invention relates to methods and compositions for treating hepatitis virus infections, especially hepatitis virus infections, particularly hepatitis B and hepatitis C, in mammals, especially humans. The methods comprise administering substituted-1,5-dideoxy-1,5-imino-D-glucitol compounds alone or in combination with nucleoside antiviral agents, nucleotide antiviral agents, mixtures thereof, or, alternatively, in combination with immunomodulating/-immunostimulating agents. Administration of substituted-1,5-dideoxy-1,5-imino-D-glucitol compounds in combination with both a nucleoside and/or nucleotide type antiviral agent and an immunomodulating/immunostimulating agent or agents is also contemplated. Combinations of anti-hepatitis viral agents show unexpected efficacy in inhibiting replication and secretion of hepatitis viruses in cells of mammals infected with these viruses. Over half the biologically important proteins are glycosylated and that glycosylation may vary with disease. Based upon this information, the use of drugs to control glycosylation patterns, glycoforms, changes or rates of change will have a biochemical effect, and may provide a beneficial therapeutic result. Control of glycolipid and glycoprotein sugar patterns as well as their synthesis and degradation leads to basic physiological effects on mammals including humans, agricultural animals and pets. Possibly, this is through influences on, for example, N-linked glycans, O-linked glycans, glucosoaminoglycans, glycosphingolipids, glycophospholipids, lectins, immuneoglobulin molecules, antibodies, glycoproteins and their biochemical intermediates or conversion products. Modification of glycosalation site occupancy influences receptor and enzyme binding site specificity, selectivity, capacity, protein folding, enzyme activity, kinetics and energetics. Glycosidase and glycosyltransferase systems are two biochemical mechanisms that are suggested to affect such systems (Dwek, Raymond A., Glycobiology: Toward Understanding the Function of Sugars, Chemical Reviews, 96, 683-720 (1996). Other hepatitis viruses significant as agents of human disease include Hepatitis A, Hepatitis B, Hepatitis C, Hepatitis Delta, Hepatitis E, Hepatitis F, and Hepatitis G (Coates, J. A. V., et.al., Exp. Opin. Ther. Patents (1995) 5(8):747-756). Hepatitis C infection is also on the increase and effective treatments are needed. In addition, there are animal hepatitis viruses that are species-specific, but

serves as excellent models for the human disease. These include, for example, those infecting ducks, woodchucks, cattle and mice. Web site: http://appft1.uspto.gov/netahtml/PTO/search-bool.html •

This invention relates to parenteral and oral-intestinal vaccines against diseases caused by enteropathogenic organisms using antigens encapsulated within biodegradable-biocompatible microspheres (matrix). Most infectious agents have their first contact with the host at a mucosal surface; therefore, mucosal protective immune mechanisms are of primary importance in preventing these agents from colonizing or penetrating the mucosal surface. Numerous studies have demonstrated that a protective mucosal immune response can best be initiated by introduction of the antigen at the mucosal surface, and parenteral immunization is not an effective method to induce mucosal immunity. Antigen taken up by the gut-associated lymphoid tissue (GALT), primarily by the Peyer's patches in mice, stimulates T helper cell (TH) to assist in IgA B cell responses or stimulates T suppressor cells (Ts) to mediate the unresponsiveness of oral tolerance. Particulate antigen appears to shift the response towards the (TH) whereas soluble antigens favor a response by the

282 Hepatitis B

(Ts). Although studies have demonstrated that oral immunization does induce an intestinal mucosal immune response, large doses of antigen are usually required to achieve sufficient local concentrations in the Peyer's patches. Unprotected protein antigens may be degraded or may complex with secretory IgA in the intestinal luman. Web site: http://appft1.uspto.gov/netahtml/PTO/search-bool.html

PRICE: Contact publisher for price. Summary: Hepatitis B virus (HBV) infection, together with hepatitis C and alcohol abuse, is among the leading causes of cirrhosis and hepatocellular carcinoma (HCC) worldwide. This chapter on the diagnosis and treatment of hepatitis B is from a book that emphasizes the approaches of evidence based medicine in gastroenterology (the study of the gastrointestinal tract and gastrointestinal diseases) and hepatology (the study of the liver and liver diseases). The natural history of chronic hepatitis is variable according to phenotypic and ethnic background, and is also influenced by viral coinfections and toxic cofactors. At least 20 percent of patients develop clinically significant liver disease in the long term. Presence of markers of HBV replication and of continuing liver necroinflammation predict an adverse outcome. Interferon therapy results in stable clearance of HBeAg in 25 percent of all patients chronically infected by type HBV, but only rarely results in HBsAg clearance. Interferon therapy results in stable clearance of HBV DNA in 25 percent of all patients chronically infected by HBe minus HBV. Lamivudine is effective in clearing HBV DNA and normalizing ALT during therapy in 65 percent of patients, but its long term effectiveness is unknown. The authors conclude that there is no acceptable evidence for a protective effect of interferon therapy against the development of hepatocellular carcinoma (HCC) in HBV related cirrhosis. 4 figures. 2 tables. 150 references. •

ISBN: 0824705823. Summary: Liver enzyme abnormalities are very common in patients infected with the human immunodeficiency virus (HIV). Chronic viral hepatitis B and C are among the leading etiological factors associated with hepatocellular (liver) injury. Improved treatments for HIV utilizing highly active antiretroviral therapy (HAART) with multidrug regimens has resulted in increased life expectancy. This change has affect the course and natural history of hepatitis B and C and increased the importance of liver disease in HIV infected patients. This chapter on HIV patients coinfected with hepatitis B and C is from a monograph on the management of chronic viral hepatitis (liver inflammation), bringing the advances of clinical and basic research into the doctor's office. This chapter uses a brief clinical case presentation in order to address the real life intricacies of managing patients who present with viral hepatitis. The case patient is a 40 year old white man with HIV and hepatitis B virus (HBV); his hepatitis B flared in the setting of immune reconstitution. Adding or substituting lamivudine 100 milligrams per day back into the regimen was effective in suppressing HBV replication, and the patient showed dramatic clinical improvement over the next 8 weeks, returning to baseline liver function. The authors note that before HAART, early HIV associated mortality and significant immunosuppression were associated with minimal to mild consequences of hepatitis viral infections in these patients. Immune reconstitution of HIV infected patients with HAART has changed the course of disease outcomes. There is now a critical need to understand the natural history and the value of treatment intervention for hepatitis viruses. 1 figure. 2 tables. 51 references.

ISBN: 0824705823. Summary: This chapter on future treatment options for hepatitis B is from a monograph on the management of chronic viral hepatitis (liver inflammation), bringing the advances of clinical and basic research into the doctor's office. This chapter uses a brief clinical case presentation in order to address the real life intricacies of managing patients who present with viral hepatitis. The case patient is a 39 year old white man who was referred in consultation seeking a second opinion regarding his well known history (10 years) of chronic hepatitis B. The authors use this case to consider the role of long term therapeutic agents, the indications for lamivudine therapy, new antivirals that may be in the research stages, and strategies to improve the host immune response and thus obtain an immunological clearance of the hepatitis B virus (HBV). The authors conclude that although significant advances have been made in the treatment of chronic hepatitis B, there is still a high proportion of these patients in whom a sustained eradication of the viral infection cannot be achieved with either interferons or lamivudine monotherapy. However, combination therapy has been shown to improve the success rate in chronic hepatitis C and HIV; the authors speculate that it may also be helpful in the treatment of chronic hepatitis B patients. The preliminary experience with combination therapy of interferons and lamivudine has been frustrating. A wide range of novel antiviral approaches such as cytokine therapy, vaccine adjuvant, DNA vaccines, antisense therapy, and other forms of gene therapy are currently under investigation. 3 figures. 1 table. 72 references.

ISBN: 0824705823. Summary: This chapter on hepatitis B virology is from a monograph on the management of chronic viral hepatitis (liver inflammation), bringing the advances of clinical and basic research into the doctor's office. Three brief clinical case presentations address the real life intricacies of managing patients who present with viral hepatitis. The authors focus on wild type hepatitis B viruses (HBV) and HBV variants. Case 1 presented with acute hepatitis, as evidenced by the presence of HBsAg and IgM antiHBc. The authors comment on the need for prophylaxis for this patient's wife. Case 2 had perinatally (during birth) acquired HBV infection with exacerbation of chronic hepatitis B. This patient may benefit from antiviral therapy if the exacerbation does not result in sustained HBeAg seroconversion. Because of his family history of hepatocellular carcinoma (HCC, liver cancer), surveillance for HCC is recommended. Case 3 most likely was infected with a precore variant, as evidenced by the detection of HBV DNA despite the presence of anti HBe. 6 figures. 1 table. 85 references.

Summary: This chapter on screening for hepatitis B virus (HBV) infection is from a guide to clinical preventive services published by the U.S. Preventive Services Task Force. Screening with hepatitis B surface antigen (HBsAg) to detect active (acute or chronic) HBV infection is recommended for all pregnant women at their first prenatal visit. The test may be repeated in the third trimester in women who are initially HBsAg negative but are at increased risk of HBV infection during pregnancy. Routine screening of the general population is not recommended. Certain persons at high risk may be screened to assess eligibility for vaccination. The chapter discusses the accuracy of screening tests, the effectiveness of early detection, and the recommendations of other groups. The chapter concludes with a summary of recommended clinical interventions. 56 references. (AA-M).

clinical and basic research into the doctor's office. This chapter uses a brief clinical case presentation in order to address the real life intricacies of managing patients who present with viral hepatitis. The case patient is a 25 year old Asian American man who presented for evaluation of recently discovered hepatitis B surface antigenemia. The patient has a significant family history of liver disease with his father having had a diagnosis of hepatocellular carcinoma (liver cancer) and chronic hepatitis B. Because the patient had persistent replication with HBeAg and HBV DNA present at follow up 3 months later, treatment was advised. The role of interferon and lamivudine were discussed and he elected to receive therapy with lamivudine. The patient had rapid normalization of liver chemistries with clearance of serum HBV DNA within 12 weeks of start of the therapy. The authors note that the treatment options for chronic HBV have broadened considerably with the advent of lamivudine, the first of undoubtedly many newer agents for therapy. There is still, however, an important role for interferon therapy in well selected patients, particularly as its successful use clearly leads to loss of HBsAg. Factors to weigh in choosing an initial agent include the patient's likely tolerance of interferon side effects and predictors of successful response, notably low pretherapy HBV DNA and elevated ALT levels. The absence of severe side effects with lamivudine makes compliance easy, although by not using interferon therapy, the patient may at least theoretically be deprived of a chance of subsequent HBsAg clearance. 2 figures. 2 tables. 72 references. •

ISBN: 0824705823. Summary: This chapter on the treatment of hepatitis B in transplant recipients is from a monograph on the management of chronic viral hepatitis (liver inflammation), bringing the advances of clinical and basic research into the doctor's office. Three clinical case presentations address the real life intricacies of managing patients who present with viral hepatitis. Originally, a high rate of graft infection and early graft failure, as well as frequent patient death, led to skepticism about the use of orthotopic liver transplantation (OLT) for chronic HBV infection. Marked improvements in long term survival have resulted from the use of low dose immunosuppressive therapy and administration of indefinite hepatitis B immune globulin. The goals of treatment of HBV infection include decreasing viral load, lessening infectivity, decreasing the level of hepatic inflammation, preventing or slowing the development of cirrhosis (liver scarring) and liver failure, delaying time to liver transplantation, and prevention of liver cancer. Lamivudine alone or in combination with hepatitis B immune globulin (HBIG) has been shown to be effective in the long term management of recipients of liver transplants. The combination of lamivudine and HBIG is probably the best current therapy, since lamivudine monotherapy, especially in the setting of immunosuppression, has a very high mutation rate leading to resistance and active viral replication in more than 40 percent of patients after 2 years of therapy posttransplantation. Patients with severe recurrent HBV infection, including fibrosing cholestatic hepatitis (FCH), can undergo liver retransplantation but costs are extremely high and long term survival is inferior to that of patients undergoing a first liver transplantation. 2 figures. 3 tables. 165 references.

availability of immunization, and risk factors for hepatitis A and C. The program then goes into more depth on hepatitis B, interviewing patients and health care providers. One young woman (age 26) who contracted hepatitis B at birth, describes her experiences with the disease and the psychosocial impact it has had on her life. The program discusses occupational risk factors, transmission, the geographic incidence and prevalence of hepatitis B, its typical course, and the problems associated with the development of chronic active hepatitis. A brief section describes the use of liver transplantation as the final option for end stage liver failure caused by hepatitis. The program then focuses on immunization programs, including those designed to vaccinate babies at birth, infants (during routine immunization), and adolescents. There is also some discussion about the difficulties of instituting successful vaccination programs for some high risk groups, including intravenous (IV) drug users and people with multiple sexual partners. •

Summary: This videotape program educates viewers about hepatitis B and its potential impact. The first part of the program, presented in the Cambodian language, features a narrator who introduces Dr. Hie-Won Hann, a physician helping Asian families fighting hepatitis B. The program shows Dr. Hann interviewing a pregnant Cambodian woman; a second scenario features Dr. Hann and the woman's family, who have all come in to learn more about hepatitis B. Topics covered include the complications of hepatitis B (acute disease, liver cancer), chronic infection with hepatitis B, how to protect a baby from getting hepatitis B, testing family members, protecting uninfected family members, treating the chronic carrier, how the disease is transmitted (perinatal, sexual transmission, and close familial contact, i.e., sharing toothbrushes, razors, etc.), why the disease is common among Asian people, and the importance of achieving widespread vaccination. The videorecording comes with an English and a Cambodian copy of the script. The second part of the tape, presented in English, features Dr. Haing S. Ngor introducing the history of Indo-Chinese people in the U.S. and stressing the important place that family serves in these cultures. The remainder of the tape is the same as the Cambodian language part, but in English.

Drug-Induced Rheumatic Syndromes Source: Bulletin on the Rheumatic Diseases. 51(4): 1-4. 2002. Contact: Available from Arthritis Foundation. 1330 West Peachtree Street, Atlanta, GA 30309. (800) 268-6942 or (404) 872-7100. Fax (404) 872-9559. Website: www.arthritis.org. Summary: This newsletter provides health professionals with information on drug induced rheumatic syndromes. Categories of drug induced rheumatic diseases are drug induced lupus (DIL), drug induced myopathy/myositis (DIM), and drug induced vasculitis (DIV). Although more than 100 drugs have been implicated in DIL, the drugs most studied have been procainamide and hydralazine. However, these drugs are not commonly prescribed today, and the illness they produce is often different from those

308 Hepatitis B

recently implicated in DIL. Minocycline is a treatment used for acne and rheumatoid arthritis that has caused immune and autoimmune phenomena. Several of the new recombinant biologics have been implicated in DIL, including interferon alpha, interferon gamma, and antitumor necrosis factor therapies. It is not possible to predict who will develop DIL, so patients with idiopathic lupus should be allowed to take potentially lupus inducing drugs but with careful monitoring. Drugs associated with the development of DIV include hematopoietic growth factors such as G-CSF and GM-CSF; vaccines for hepatitis B, influenza, and others; and leukotriene inhibitors. The article concludes that the number of drugs that are capable of inducing rheumatic syndromes is growing. Elements in the assessment of a possible association between exposure and the development of a rheumatic disorder include temporal association, lack of likely alternative explanations, rechallenge, and biological plausibility. 1 table and 23 references.

Hepatitis B in Asia Source: Asian Pacific Gastroenterology News. Issue 4: 12-13. June 2000. Contact: Available from Blackwell Science Asia. 54 University Street, Carlton, Victoria 3053, Australia. 61 3 9347 0300. Fax 61 3 9347 5001. E-mail: [email protected]. Summary: Five to 20 percent of the population of Asia and Africa are chronically infected with hepatitis B virus (HBV). This article reviews the main issues related to hepatitis B in Asia, including the evaluation and treatment of infected but asymptomatic subjects, the so-called HBV carriers; the continued horizontal spread of HBV infection, emergence of HBV mutants, and implementation of vaccination programs. The author contends that the term 'carrier' should therefore be deleted from the terminology of hepatitis B and should be replaced by 'chronic hepatitis B virus infection.' Evaluation of a subject with chronic HBV infection should include a reliable ALT (repeated three times), an HbeAg test, and if needed, an HBV DNA ultrasound and liver biopsy. The prevalence of HBV and hepatitis C (HCV) in chronic liver disease has been reported to be approximately 15 percent in the Asian region. In several countries in Asia, vaccination against HBV has been successfully included in the EPI program. This has led to a substantial reduction in the chronic HBV infection in the pediatric population. 1 table. 6 references.

Summary: Hepatitis B vaccines provide protection against serious and life threatening liver diseases, including cancer of the liver. This article reviews the safety and efficacy of hepatitis B vaccine. The author notes that recent news items have questioned the safety of hepatitis B vaccines and suggested associations between the vaccine and multiple sclerosis (MS) and other autoimmune disorders. The author emphasizes that these news reports have not included the results of expert panels who have carefully reviewed the data and found no scientific evidence of a causal relationship between hepatitis B vaccine and MS and other disorders. The author describes this review process and refers readers to numerous vaccine safety resources (telephone numbers and websites). The author stresses that parents should not be misled by the occasional inflammatory reports in the press. Hepatitis B vaccines are very safe and effective and should continue to be given to all children as part of their routine vaccination schedule. •

Be As Sure As You Can Be!: Give Babies Hepatitis B Vaccine at Birth Source: Needle Tips and the Hepatitis B Coalition News. 10(1): 3. Spring-Summer 2000. Contact: Available from Hepatitis B Coalition. Immunization Action Coalition, 1573 Selby Avenue, Suite 229, St. Paul, MN 55104. (612) 647-9009. Fax (612) 647-9131. E-mail: [email protected]. Website: www.winternet.com. Summary: In the past year, the successful strategy of initiating hepatitis B immunization at birth has been interrupted by concerns regarding thimerosal, the commonly used vaccine preservative. This article briefly reviews the concerns with thimerosal, then notes that vaccine manufacturers now have sufficient supplies of preservative free hepatitis B vaccine to meet the vaccination needs of all children in the United States. Advisory groups have recommended that routine newborn vaccination policies be reintroduced in hospitals where they were discontinued. In addition, both advisory groups (the Centers for Disease Control and Prevention, or CDC, and the American Academy of Pediatrics, AAP) have emphasized that hepatitis B vaccination should not be delayed for infants born to HBsAg negative mothers as was recommended by the AAP in July 1999. The article lists and discusses five reasons that infant vaccine is critical: prevention of perinatal hepatitis B virus (HBV) infection; hepatitis B vaccination at birth provides a safety net; infants and children are exposed to HBV even though their mothers are HBsAg negative; infant immunization is part of the nation's strategy to eliminate HBV transmission; and the birth dose of hepatitis B vaccine increases completion of the three dose series and other childhood vaccines. 1 reference.

Website: www.winternet.com. Summary: These guidelines can be used to help a hospital establish standing orders for preventing perinatal hepatitis B virus (HBV) transmission in the labor and delivery and nursery units. The guidelines stress that procedures must already be in place to review the hepatitis B surface antigen (HBsAg) test results of all pregnant women at the time of

310 Hepatitis B

hospital admission and to give immunoprophylaxis within 12 hours after birth to infants of HBsAg-positive mothers and infants of mothers who do not have documentation of HBsAg test results in their charts. Administration of hepatitis B (HepB) vaccine at birth to all infants is recommended by CDC's Advisory Committee on Immunization Practices, the American Academy of Pediatrics, the American Academy of Family Physicians, and the American College of Obstetricians and Gynecologists.

CHAPTER 10. RESEARCHING MEDICATIONS Overview While a number of hard copy or CD-ROM resources are available for researching medications, a more flexible method is to use Internet-based databases. Broadly speaking, there are two sources of information on approved medications: public sources and private sources. We will emphasize free-to-use public sources.

U.S. Pharmacopeia Because of historical investments by various organizations and the emergence of the Internet, it has become rather simple to learn about the medications recommended for hepatitis B. One such source is the United States Pharmacopeia. In 1820, eleven physicians met in Washington, D.C. to establish the first compendium of standard drugs for the United States. They called this compendium the U.S. Pharmacopeia (USP). Today, the USP is a nonprofit organization consisting of 800 volunteer scientists, eleven elected officials, and 400 representatives of state associations and colleges of medicine and pharmacy. The USP is located in Rockville, Maryland, and its home page is located at http://www.usp.org/. The USP currently provides standards for over 3,700 medications. The resulting USP DI® Advice for the Patient® can be accessed through the National Library of Medicine of the National Institutes of Health. The database is partially derived from lists of federally approved medications in the Food and Drug Administration’s (FDA) Drug Approvals database, located at http://www.fda.gov/cder/da/da.htm. While the FDA database is rather large and difficult to navigate, the Phamacopeia is both user-friendly and free to use. It covers more than 9,000 prescription and over-the-counter medications. To access this database, simply type the following hyperlink into your Web browser: http://www.nlm.nih.gov/medlineplus/druginformation.html. To view examples of a given medication (brand names, category, description, preparation, proper use, precautions, side effects, etc.), simply follow the hyperlinks indicated within the United States Pharmacopeia (USP). Below, we have compiled a list of medications associated with hepatitis B. If you would like more information on a particular medication, the provided hyperlinks will direct you to ample documentation (e.g. typical dosage, side effects, drug-interaction risks, etc.). The

Mosby’s Drug Consult™ Mosby’s Drug Consult™ database (also available on CD-ROM and book format) covers 45,000 drug products including generics and international brands. It provides prescribing information, drug interactions, and patient information. Subscription information is available at the following hyperlink: http://www.mosbysdrugconsult.com/. PDRhealth The PDRhealth database is a free-to-use, drug information search engine that has been written for the public in layman’s terms. It contains FDA-approved drug information adapted from the Physicians’ Desk Reference (PDR) database. PDRhealth can be searched by brand name, generic name, or indication. It features multiple drug interactions reports. Search PDRhealth at http://www.pdrhealth.com/drug_info/index.html. Other Web Sites Drugs.com (www.drugs.com) reproduces the information in the Pharmacopeia as well as commercial information. You may also want to consider the Web site of the Medical Letter, Inc. (http://www.medletter.com/) which allows users to download articles on various drugs and therapeutics for a nominal fee.

Researching Orphan Drugs Although the list of orphan drugs is revised on a daily basis, you can quickly research orphan drugs that might be applicable to hepatitis B by using the database managed by the National Organization for Rare Disorders, Inc. (NORD), at http://www.rarediseases.org/. Scroll down the page, and on the left toolbar, click on “Orphan Drug Designation Database.” On this page (http://www.rarediseases.org/search/noddsearch.html), type “hepatitis B” (or synonyms) into the search box, and click “Submit Query.” When you receive your results, note that not all of the drugs may be relevant, as some may have been withdrawn from orphan status. Write down or print out the name of each drug and the relevant contact information. From there, visit the Pharmacopeia Web site and type the name of each orphan drug into the search box at http://www.nlm.nih.gov/medlineplus/druginformation.html. You may need to contact the sponsor or NORD for further information. NORD conducts “early access programs for investigational new drugs (IND) under the Food and Drug Administration’s (FDA’s) approval ‘Treatment INDs’ programs which allow for a limited number of individuals to receive investigational drugs before FDA marketing approval.” If the orphan product about which you are seeking information is approved for marketing, information on side effects can be found on the product’s label. If the product is not approved, you may need to contact the sponsor. The following is a list of orphan drugs currently listed in the NORD Orphan Drug Designation Database for hepatitis B: •

Recommendations for Preventing Transmission of Human Immunodeficiency Virus and Hepatitis B Virus to Patients During Exposure - Prone Invasive Procedures Contact: CDC National Prevention Information Network, PO Box 6003, Rockville, MD, 20849-6003, (800) 458-5231, http://www.cdcnpin.org. Summary: This report contains recommendations from the Centers for Disease Control and Prevention (CDC) on preventing transmission of HIV and the Hepatitis B virus to patients during invasive procedures. It advises health care workers to follow universal precautions, which require that blood and body fluids of all patients be handled as if they contain bloodborne pathogens. For the protection of patients, equipment and devices that enter sterile areas of the body should be sterilized before being used on each patient; equipment and devices that touch intact mucous membrane should be sterilized when possible or undergo high-level disinfection; and equipment and devices that do not touch the patient or that touch only intact skin need cleaning with a detergent. The report looks into incidence of the transmission of Hepatitis B virus and HIV during invasive procedures. It concludes with recommendations, which say that all health care workers should adhere to universal precautions; currently available data provide no basis for recommendations to restrict the practice of health care workers infected with either virus who perform invasive procedures but not exposure-prone ones. The recommendations also say that exposure-prone procedures should be identified by medical, surgical, and dental organizations and institutions; heath care workers who perform such procedures should know their HIV-antibody status and their Hepatitis B status; and infected workers should not perform exposure-prone procedures unless they have been advised by an expert review panel on when they may continue to perform such procedures. Mandatory testing is not recommended, and health care workers whose practices are modified because of infection status should be provided other opportunities to continue with appropriate patient-care activities. Patients who have had exposure-prone procedures performed by infected workers should be notified on a case-by-case basis.

The databases available are listed in the drop box next to “Search.” Enter “hepatitis B” (or synonyms) into the search box and click “Go.” Jablonski’s Multiple Congenital Anomaly/Mental Retardation (MCA/MR) Syndromes Database24 This online resource has been developed to facilitate the identification and differentiation of syndromic entities. Special attention is given to the type of information that is usually limited or completely omitted in existing reference sources due to space limitations of the printed form. At http://www.nlm.nih.gov/mesh/jablonski/syndrome_toc/toc_a.html, you can search across syndromes using an alphabetical index. Search by keywords at http://www.nlm.nih.gov/mesh/jablonski/syndrome_db.html. The Genome Database25 Established at Johns Hopkins University in Baltimore, Maryland in 1990, the Genome Database (GDB) is the official central repository for genomic mapping data resulting from the Human Genome Initiative. In the spring of 1999, the Bioinformatics Supercomputing Centre (BiSC) at the Hospital for Sick Children in Toronto, Ontario assumed the management of GDB. The Human Genome Initiative is a worldwide research effort focusing on structural analysis of human DNA to determine the location and sequence of the estimated 100,000 human genes. In support of this project, GDB stores and curates data generated by researchers worldwide who are engaged in the mapping effort of the Human Genome Project (HGP). GDB’s mission is to provide scientists with an encyclopedia of the human genome which is continually revised and updated to reflect the current state of scientific knowledge. Although GDB has historically focused on gene mapping, its focus will broaden as the Genome Project moves from mapping to sequence, and finally, to functional analysis. 24

APPENDIX B. PATIENT RESOURCES Overview Official agencies, as well as federally funded institutions supported by national grants, frequently publish a variety of guidelines written with the patient in mind. These are typically called “Fact Sheets” or “Guidelines.” They can take the form of a brochure, information kit, pamphlet, or flyer. Often they are only a few pages in length. Since new guidelines on hepatitis B can appear at any moment and be published by a number of sources, the best approach to finding guidelines is to systematically scan the Internet-based services that post them.

Patient Guideline Sources The remainder of this chapter directs you to sources which either publish or can help you find additional guidelines on topics related to hepatitis B. Due to space limitations, these sources are listed in a concise manner. Do not hesitate to consult the following sources by either using the Internet hyperlink provided, or, in cases where the contact information is provided, contacting the publisher or author directly. The National Institutes of Health The NIH gateway to patients is located at http://health.nih.gov/. From this site, you can search across various sources and institutes, a number of which are summarized below. Topic Pages: MEDLINEplus The National Library of Medicine has created a vast and patient-oriented healthcare information portal called MEDLINEplus. Within this Internet-based system are “health topic pages” which list links to available materials relevant to hepatitis B. To access this system, log on to http://www.nlm.nih.gov/medlineplus/healthtopics.html. From there you can either search using the alphabetical index or browse by broad topic areas. Recently, MEDLINEplus listed the following when searched for “hepatitis B”:

(215) 489-4900 Fax: (215) 489-4920 Email: [email protected]. Website: www.hepb.org. PRICE: Full-text available online at no charge. Summary: Hepatitis B (a type of liver inflammation caused by a virus) is the world's most common, serious liver infection. Hepatitis B is caused by the hepatitis B virus (HBV), which can be transmitted through blood, sex, shared needles, and from an infected mother to her newborn during delivery. HBV is spreading because many chronic hepatitis B carriers are not aware that they have the virus and unknowingly pass it on to those who are in close contact with them. This brochure reviews the basics of hepatitis B and its prevention. The brochure discusses who is most at risk for contracting the virus, HBV infection in children and infants, the role of vaccination against HBV, and the work of the Hepatitis B Foundation (WWW.hepb.org). The brochure concludes with a tear-off form with which readers can contribute to the Hepatitis B Foundation and request additional information; a brief description of the goals and activities of the Foundation is also provided. 3 figures.

Fax (973) 256-3214. E-mail: [email protected]. Website: www.liverfoundation.org. PRICE: $0.50 for single copy; bulk orders available; plus shipping and handling. Summary: Hepatitis B virus (HBV) infection is a serious liver infection caused by a virus and spread by contact with infected body fluids. One way that the virus is transmitted is during birth when virus in the blood and vaginal fluids of the mother readily expose the baby to the disease. This fact sheet explores strategies that can break the cycle of hepatitis B transmission from mothers to their newborns. The fact sheet covers the problem of hepatitis B, groups at high risk for hepatitis B, recommended hepatitis B screening, the risks to babies born of carrier mothers, the use of hepatitis B immune globulin and hepatitis B vaccine, the estimated number of hepatitis B carriers in pregnant women in the United States, the long term risks associated with hepatitis B (including increased liver cancer risk), and vaccine availability. The fact sheet concludes with the contact information for the American Liver Foundation, a nonprofit, national voluntary health organization (www.liverfoundation.org). •

PRICE: Single copy free for patients; available to health professionals through local sales representatives. Summary: Hepatitis is an inflammation of the liver caused by a virus, drugs, or other factors. This fact sheet reviews basic information about hepatitis B virus (HBV) and hepatitis C virus (HCV). There are at present six types of viral hepatitis: A, B, C, D, E, and G. They differ in how they are transmitted as well as how long and how severely they affect the patient. Hepatitis A and E, milder forms, are spread through contaminated foods or water, while hepatitis B, C, and D (more serious forms) are spread through contact with human blood or by sexual activity. Hepatitis B and C have the greatest potential for long term liver damage. There is a vaccine to prevent hepatitis B, but not hepatitis C. Many people have few or no symptoms with HBV and HCV; blood tests may discover the infection. Liver function tests can then be performed to measure the severity of infection. Both hepatitis B and C are very common and can be either acute (short term, less than 6 months) or chronic (long term, more than 6 months) infections. The fact sheet stresses the important, varied roles of the liver, noting that a liver damaged by hepatitis cannot handle all these tasks very well. Hepatitis C can lead to permanent liver damage that may require a liver transplant. Almost one third of all liver transplants in the United States are needed because the patient had chronic hepatitis C. The fact sheet concludes by briefly reviewing prevention strategies for hepatitis B and C: never share needles or personal items that can hold blood (toothbrushes, razors), make sure that any tattooing or body piercing is done with sterile instruments, avoid multiple sex partners, and practice safer sex (use a latex condom). The fact sheet concludes with two toll free telephone hotlines where readers can get additional information: 800-GO-LIVER (465-4837) and 888-4HEP-ABC (443-7222).

Every Week Thousands of Sexually Active People Are Infected With Hepatitis B Contact: Immunization Action Coalition, 1573 Selby Ave Ste 234, St Paul, MN, 55104, (651) 647-9009, http://www.immunize.org. Summary: This brochure, written for the general public, discusses the hepatitis B virus (HBV). Hepatitis B is a sexually transmitted liver disease, caused by HBV, which is much easier to contract than the human immunodeficiency virus (HIV)/acquired immune deficiency syndrome (AIDS) and can cause severe liver disease, scarring, and liver cancer. A quiz is supplied in the brochure for individuals to use to assess their risks for HBV. HBV can be spread through unprotected vaginal or anal sex, needle-sharing for injection drugs use, contact with open sores, and prolonged exposure to an individual with HBV. It can also be contracted through body piercing or tattooing with unsterile equipment, the sharing of personal products that may contain blood such as toothbrushes or razors, and human bites. Individuals can protect themselves from HBV through vaccination and by practicing safer sex. The symptoms of hepatitis B include loss of appetite, nausea, fever, dark-colored urine, jaundice, fatigue, joint pain, and a bloated and tender belly. Most people who get HBV will fully recover; however, a small percentage will carry the infection in their bodies for life. The only way for individuals to know if they have been infected with HBV is to get tested. The HBV vaccine will not protect individuals from the hepatitis A vaccine (HAV) or the hepatitis C virus (HCV). The HBV vaccine may be available at no charge through clinics or health departments.

the possibilities of liver cirrhosis and primary hepatocellular carcinoma (HCC, or liver cancer); the liver damage caused by HBV; the need for ongoing patient followup, even when test batteries indicate a lower infection rate; management of patients who are chronically infected with HBV; and the treatment modalities. Approximately 40 percent of suitable patients with chronic HBV with significant liver damage and ongoing viral replication benefit from treatment with interferon. Those who are most likely to respond to treatment for HBV are those who have evidence of liver damage and low HBV DNA levels. Because interferon may have significant risks and side effects associated with its use, treatment should be carried out by a gastroenterologist or hepatologist with experience in the antiviral treatment of chronic hepatitis. 1 table.

Summary: This fact sheet, for individuals with the hepatitis B virus (HBV), provides information about self-care and protecting others from HBV. Individuals with HBV should see their doctors at least once a year for a liver evaluation. It is recommended that HBV carriers discuss with their doctors if they are eligible for the medication, interferon alfa-2b, and get periodic tests to detect evidence of liver cancer. Individuals should talk with their physicians about the medications they are taking, should tell them if they are pregnant, and should avoid alcoholic beverages. If persons with HBV have advanced beyond being 'healthy carriers,' they should get an influenza and a hepatitis A virus (HAV) vaccine and should not eat raw oysters. HBV carriers can help to protect others from this disease by informing their sex partners and health care workers of their infection, making sure all household members see a physician, covering all cuts and sores with bandages, disposing of personal items that may contain blood, washing their hands after touching blood or body fluids, and cleaning up blood spills. To protect others from infection, individuals with HBV should not share personal products that may contain blood, share food that has been in their mouths, share needles or syringes, or donate blood or organs.

Summary: This pamphlet informs the readers about the hepatitis B virus (HBV). HBV is a viral disease that affects the liver, and is transmitted through unprotected sex, needle sharing among injection drugs users (IDUs), the use of contaminated needles or other paraphernalia for piercings or tattoos, needle stick injuries, or the use of a toothbrush or razor of an infected person. Symptoms of HBV include fatigue, nausea, fever, loss of appetite, stomach pain, diarrhea, dark yellow urine, light-colored stools, and yellowing of the eyes and skin. Some individuals do not experience symptoms. HBV can be diagnosed by testing one's blood or through a liver biopsy. Treatment may involve a drug called interferon or long-term outcomes may include the need for surgery (i.e., a liver transplant). Readers can protect themselves against HBV by getting a vaccination, practicing safer sex with a condom, avoiding sharing drug needles with others, observing universal precautions if working in health or safety setting, avoiding sharing toothbrushes and razors, and insisting that clean needles and other paraphernalia are used when receiving a tattoo.

Prevent Hepatitis B: Get Vaccinated Summary: This pamphlet promotes prevention of hepatitis B virus (HBV) infection by getting vaccinated. The pamphlet explains the symptoms of HBV infection, the seriousness of the disease, the truth and myths about transmission, and various ways of preventing infection. It advises persons practicing high-risk behaviors, as well as everyone under nineteen years of age, to get vaccinated against HBV. Each year, thousands of people of all ages get hepatitis B and about 5,000 die of chronic (life-long) liver problems caused by HBV infection. HBV is spread by contact with the blood of an infected person or by having sex with an infected person, and a woman who has hepatitis B can spread the virus to her baby during birth. HBV is not spread through sneezing or coughing, kissing or hugging, the sharing of eating utensils, glasses, breast feeding, food or water, or casual contact. Only a blood test can tell for sure if an individual is infected with HBV. To prevent HBV infection, individuals should get vaccinated, practice "safer" sex, not share anything that might have blood on it, think about the health risks associated with getting a tattoo or body piercing, and follow standard precautions when working in healthcare settings. Most individuals do not need to get their blood tested after getting the vaccine. Individuals who should get a blood test one to two months after completing the vaccination series include those whose sex partner has chronic hepatitis B, whose immune system is not working well, or whose job exposes them to human blood.

In addition, the pamphlet identifies ways people can protect themselves from the virus, including abstaining from sex, practicing safer sex, stopping injection drug use, avoiding sharing or reusing needles if continuing injection drug use, and avoiding sharing personal items. •

Chronic Hepatitis B and Chronic Hepatitis C Source: American Family Physician. 54(5): 1603-1605. October 1996. Summary: This patient education fact sheet describes chronic hepatitis B and chronic hepatitis C, similar kinds of liver infection that are caused by viruses. Written in a question and answer format, the fact sheet describes how a person can contract hepatitis B or hepatitis C, the symptoms of each disease in both the acute and chronic phases, the difference between acute hepatitis and chronic hepatitis, diagnostic tests used to confirm chronic hepatitis, treatment options (notably interferon alpha-2b), the side effects of interferon alpha-2b, and the prevention of hepatitis B or hepatitis C. The best way to prevent hepatitis B or hepatitis C is to avoid practices that increase the risk of getting infected. The risk of getting infected is increased by sharing needles and having sex with multiple partners. A vaccine is available for hepatitis B. This vaccine is recommended for people at high risk of contracting hepatitis B, including health care workers, all children, drug users, people who get tattoos or body piercing, prostitutes, and homosexuals with multiple sex partners. No vaccine is available for hepatitis C.

What I Need to Know About Hepatitis B Source: National Institute of Diabetes and Digestive and Kidney Diseases, National Institutes of Health http://www.healthfinder.gov/scripts/recordpass.asp?RecordType=0&RecordID=2299 The NIH Search Utility

The NIH search utility allows you to search for documents on over 100 selected Web sites that comprise the NIH-WEB-SPACE. Each of these servers is “crawled” and indexed on an ongoing basis. Your search will produce a list of various documents, all of which will relate in some way to hepatitis B. The drawbacks of this approach are that the information is not organized by theme and that the references are often a mix of information for professionals and patients. Nevertheless, a large number of the listed Web sites provide useful background information. We can only recommend this route, therefore, for relatively rare or specific disorders, or when using highly targeted searches. To use the NIH search utility, visit the following Web page: http://search.nih.gov/index.html. PEDBASE Similar to NORD, PEDBASE covers relatively rare disorders, limited mainly to pediatric conditions. PEDBASE was designed by Dr. Alan Gandy. To access the database, which is more oriented to researchers than patients, you can view the current list of health topics covered at the following Web site: http://www.icondata.com/health/pedbase/pedlynx.htm. Additional Web Sources A number of Web sites are available to the public that often link to government sites. These can also point you in the direction of essential information.

APPENDIX C. FINDING MEDICAL LIBRARIES Overview In this Appendix, we show you how to quickly find a medical library in your area.

Preparation Your local public library and medical libraries have interlibrary loan programs with the National Library of Medicine (NLM), one of the largest medical collections in the world. According to the NLM, most of the literature in the general and historical collections of the National Library of Medicine is available on interlibrary loan to any library. If you would like to access NLM medical literature, then visit a library in your area that can request the publications for you.26

Finding a Local Medical Library The quickest method to locate medical libraries is to use the Internet-based directory published by the National Network of Libraries of Medicine (NN/LM). This network includes 4626 members and affiliates that provide many services to librarians, health professionals, and the public. To find a library in your area, simply visit http://nnlm.gov/members/adv.html or call 1-800-338-7657.

Medical Libraries in the U.S. and Canada In addition to the NN/LM, the National Library of Medicine (NLM) lists a number of libraries with reference facilities that are open to the public. The following is the NLM’s list and includes hyperlinks to each library’s Web site. These Web pages can provide information on hours of operation and other restrictions. The list below is a small sample of

Dictionary 387

Complement: A term originally used to refer to the heat-labile factor in serum that causes immune cytolysis, the lysis of antibody-coated cells, and now referring to the entire functionally related system comprising at least 20 distinct serum proteins that is the effector not only of immune cytolysis but also of other biologic functions. Complement activation occurs by two different sequences, the classic and alternative pathways. The proteins of the classic pathway are termed 'components of complement' and are designated by the symbols C1 through C9. C1 is a calcium-dependent complex of three distinct proteins C1q, C1r and C1s. The proteins of the alternative pathway (collectively referred to as the properdin system) and complement regulatory proteins are known by semisystematic or trivial names. Fragments resulting from proteolytic cleavage of complement proteins are designated with lower-case letter suffixes, e.g., C3a. Inactivated fragments may be designated with the suffix 'i', e.g. C3bi. Activated components or complexes with biological activity are designated by a bar over the symbol e.g. C1 or C4b,2a. The classic pathway is activated by the binding of C1 to classic pathway activators, primarily antigen-antibody complexes containing IgM, IgG1, IgG3; C1q binds to a single IgM molecule or two adjacent IgG molecules. The alternative pathway can be activated by IgA immune complexes and also by nonimmunologic materials including bacterial endotoxins, microbial polysaccharides, and cell walls. Activation of the classic pathway triggers an enzymatic cascade involving C1, C4, C2 and C3; activation of the alternative pathway triggers a cascade involving C3 and factors B, D and P. Both result in the cleavage of C5 and the formation of the membrane attack complex. Complement activation also results in the formation of many biologically active complement fragments that act as anaphylatoxins, opsonins, or chemotactic factors.
