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 cirrhosis 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 cirrhosis, 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 cirrhosis, 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 cirrhosis. 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 cirrhosis, 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 cirrhosis. The Editors

CHAPTER 1. STUDIES ON CIRRHOSIS Overview In this chapter, we will show you how to locate peer-reviewed references and studies on cirrhosis.
The Combined Health Information Database The Combined Health Information Database summarizes studies across numerous federal agencies. To limit your investigation to research studies and cirrhosis, 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 “cirrhosis” (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: •
Relationship of Acute Transfusion-Associated Hepatitis to the Development of Cirrhosis in the Presence of Alcohol Abuse Source: Annals of Internal Medicine. 134(2): 120-124. January 16, 2001. Contact: Available from American College of Physicians. American Society of Internal Medicine. 190 North Independence Mall West, Philadelphia, PA 19106-1572. Website: www.acponline.org. Summary: Although concomitant (occurring at the same time) alcoholism is widely believed to enhance liver disease progression in persons with hepatitis C virus (HCV) infection, this relationship has not been well quantified. This article reports on a study undertaken to quantify the relationship of transfusion associated HCV infection and history of heavy alcohol abuse to the development of cirrhosis (liver scarring). The
4
Cirrhosis
retrospective cohort study featured extensive followup of 1,030 patients in prospective investigations of transfusion associated viral hepatitis conducted in the United States between 1968 and 1980. Development of cirrhosis and history of heavy alcohol abuse were determined from review of interviews with patients or their proxies, medical records, death certificates, and autopsy and biopsy reports. The absolute risk for cirrhosis was 17 percent among patients with transfusion associated HCV; 3.2 percent among patients with transfusion associated nonA, nonB, nonC hepatitis; and 2.8 percent among controls. A history of heavy alcohol abuse was associated with a fourfold increased risk for cirrhosis. Hepatitis C virus infection plus a history of heavy alcohol abuse led to a substantial increase in risk for cirrhosis, compared with controls without such a history. The authors stress that this finding emphasizes the need to counsel such patients about their drinking habits. 2 tables. 19 references. •
Risk Factors for Primary Biliary Cirrhosis in a Cohort of Patients from the United States Source: Hepatology. 33(1): 16-21. January 2001. Contact: Available from W.B. Saunders Company. 6277 Sea Harbor Drive, Orlando, FL 19106-3399. (800) 654-2452 or (407) 345-4000. Summary: Although the etiology (cause) of primary biliary cirrhosis (PBC) remains unknown, environmental factors may act to trigger the disease in genetically susceptible hosts. This article reports on a study undertaken to assess specific risk factors. In the study, the authors conducted a survey using standardized NHANES questions to 241 PBC patients in the United States, 261 of their siblings, and 141 friends without PBC. The overall response rate was 199 of 241 (83 percent) among PBC cases, 171 of 261 (67 percent) among siblings, and 141 of 225 (62.7 percent) among friend controls. The female to male ratio among cases in this sample was approximately 10 to 1, the mean age was 53 years, and 97 percent were Caucasian. Other autoimmune diseases reported most frequently by PBC cases included Sjogren's syndrome (17.4 percent) and Raynaud's syndrome (12.5 percent). Approximately 6 percent of cases reported at least one family member with PBC. Adjusted odds ratios (OR) were elevated for cases compared with friends for other autoimmune diseases, smoking, tonsillectomy, and vaginal or urinary tract infection (UTI) in females only. Similarly elevated ORs were observed for these risk factors when cases were compared with their siblings. The higher rate of UTI among cases is particularly interesting in light of previous data, and raises the possibility of an infectious etiology for PBC and of molecular mimicry as an etiologic mechanism. The significance of smoking supports the findings of previous studies and raises the issue of the influence of smoking on the immune system. 5 tables. 34 references.

Hepatitis C, Cryoglobulinemia, and Cirrhosis: A Meta-Analysis Source: Hepatology. 36(4 Part 1): 978-985. October 2002. Contact: Available from W.B. Saunders Company. 6277 Sea Harbor Drive, Orlando, FL 19106-3399. (800) 654-2452 or (407) 345-4000. Summary: Approximately 40 percent of patients with chronic hepatitis C virus (HCV) infection develop detectable serum cryoglobulins or cryoprecipitates (CP), although most do not show clinical or physical signs of syndromic cryoglobulinemia. Although association of HCV with the extrahepatic (outside the liver) complications of cryoglobulinemia is widely recognized, the relationship of cryoglobulinemia with liver disease is unclear. This article reports on a study of the relationship between CP and cirrhosis that also determined whether the development of CP is a true covariate for
Studies

progressive liver disease or a confounding variable that impacts cirrhosis because of patient age, duration of disease, or differences in gender. The authors performed a metaanalysis of 19 studies published between 1994 and 2001. The incidence of cirrhosis (liver scarring) was compared in patients with and without CP after adjustments for accepted risk factors for progressive liver disease, including age, gender, and estimated duration of disease (EDD). A total of 2,323 patients with chronic HCV were identified, with 1,022 (44 percent) having detectable CP. Cirrhosis was present in 40 percent of patients with CP but only 17 percent of patients with CP. After adjusted for age, gender, and EDD, the combined odds ratio for incidence of cirrhosis in patients CP positive versus CP negative was 4.87, indicating a highly significant association between cirrhosis and cryoglobulinemia. The authors conclude that cryoglobulins may be a useful prognostic indicator for increased risk of cirrhosis with chronic hepatitis C. 1 figure. 4 tables. 44 references. •
Minimizing Ascites: Complication of Cirrhosis Signals Clinical Deterioration Source: Postgraduate Medicine. 109(2): 91-96, 101-103. February 2001. Contact: Available from McGraw-Hill, Inc. 1221 Avenue of the Americas, New York, NY 10020. (612) 832-7869. Summary: Ascites, the pathologic accumulation of fluid in the peritoneal cavity, is a common and serious complication of cirrhosis (scarring) of the liver. The development of ascites is associated with a grave prognosis: 50 percent of patients die within 2 years of diagnosis. This article describes strategies to minimize ascites and its sequelae. Proper management with a combination of dietary, medical, and surgical approaches is essential to prolong life and improve its quality. Patients with ascites are at risk for ascitic fluid infections and neurohormonal dysregulation that can lead to hepatorenal syndrome. Early recognition of these complications allows therapeutic interventions that minimize further clinical deterioration in already chronically ill patients. Treatment goals include symptoms relief, correction of underlying pathophysiologic abnormalities (i.e., renal sodium retention, sinusoidal portal hypertension), prevention and treatment of complications of ascites, and improvement of outcome. Treatment options range from bed rest to orthotopic liver transplantation, and can include dietary sodium restriction, diuretic therapy, large volume paracentesis (removal of 5 liters or more of ascitic fluid during a single session), peritoneovenous shunt (to return ascitic fluid directly from the peritoneal cavity to the systemic circulation), transjugular intrahepatic portasystemic shunt (TIPS), and liver transplantation. Potential complications of ascites include refractory ascites, hepatorenal syndrome, and spontaneous bacterial peritonitis. 3 tables. 17 references.

Summary: Helicobacter pylori associated peptic ulcer is a frequent complication in patients with cirrhosis (scarring of the liver) and its morbidity rate (associated illness or disease complications) is high. In spite of this, diagnostic methods for H. pylori infection have not been fully evaluated in these patients. This article reports on a study undertaken to evaluate H. pylori diagnostic methods in patients with liver cirrhosis (n =

Cirrhosis
101). Results showed that 62 patients were positive for H. pylori and 35 were negative for H. pylori infection; four were indeterminate. The sensitivity and specificity were 90.4 percent and 100 percent, respectively, for antral histology; 100 percent and 100 percent for gastric body histology; 90.4 percent and 100 percent for antral immunohistochemistry; 96.2 percent and 96.7 percent for body immunochemistry; 85.7 percent and 97 percent for rapid urease test; 83.6 percent and 55.9 percent for serology; 96.4 percent and 97.1 percent for 13C urea breath test; and 75.4 percent and 94.1 percent for fecal antigen. The authors conclude that the most reliable tests for H. pylori infection in cirrhosis patients were the 13C urea breath test and gastric body histology. 1 figure. 4 tables. 28 references. •
Hepatorenal Syndrome in Cirrhosis: Pathogenesis and Treatment Source: Gastroenterology. 122(6): 1658-1676. 2002. Contact: Available from W.B. Saunders Company. 6277 Sea Harbor Drive, Orlando, FL 32887-4800. (800) 654-2452. Website: www.gastrojournal.org. Summary: Hepatorenal syndrome (HRS) is a major complication in cirrhosis (liver scarring), with an annual incidence in patients with ascites (fluid accumulation) of approximately 8 percent. HRS develops at the latest phase of the disease and, although initially considered not to have an impact on the patient's prognosis (patients would die with and not by the kidney failure), there is now evidence that HRS is an important determinant in survival. This article reviews the publications on HRS, highlighting those aspects of HRS that are important to understand the pathogenesis (development of the disease) and the rational basis of the modern therapy of this syndrome. The most characteristic feature of HRS is a functional renal (kidney) failure caused by an intense renal vasoconstriction, the syndrome is also a more generalized process affecting the heart, brain, and the splanchnic organs (the internal organs). Long term administration of IV albumin and vasoconstrictors or the correction of portal hypertension with a TIPS (transjugular intrahepatic portacaval shunt) are effective treatments of HRS, improve the survival rate, and may serve as a bridge to liver transplantation, which is the treatment of choice in these patients. 11 figures. 2 tables. 187 references.

Optimal Timing of Liver Transplantation for Primary Bilary Cirrhosis Source: Hepatology. 28(1): 33-38. July 1998. Contact: Available from W.B. Saunders Company. 6277 Sea Harbor Drive, Orlando, FL 19106-3399. (800) 654-2452 or (407) 345-4000. Summary: In 1989, the authors of this article reported on the efficacy of liver transplantation in primary biliary sclerosis (PBC) by demonstrating that patient survival following transplantation was significantly better than without transplantation as predicted by a mathematical survival model. In this article, the same authors report on a study undertaken to determine an optimal time to perform liver transplantation. A total of 143 patients with PBC undergoing liver transplantation were followed prospectively. Disease severity was measured immediately before transplantation by a summary score (risk score) that is used in the Mayo natural history model and includes age, bilirubin, albumin, prothrombin time, and presence or absence of edema. The influence of disease severity immediately pretransplantation on resource utilization for liver transplantation was assessed. Compared with the 1989 report, liver transplantation in this group was performed at an earlier stage (e.g., median risk score of 7.5 versus 8.3 in the earlier study). Following transplantation, patient survival probabilities at 1, 2, and 5 years were 93 percent, 90 percent, and 88 percent, respectively. The risk of death following
Studies
7
transplantation remained low until reaching a risk score of 7.8. By contrast, risk scores in excess of 7.8 were associated with a progressively higher mortality rate. Resource utilization measured by the number of days in the intensive care unit and hospital and the requirement for intraoperative blood transfusions was significantly greater in recipients who had higher risk scores before transplantation. The authors conclude that the optimal timing for liver transplantation in patients with PBC, as determined by survival and resource utilization, appears to be at a risk score of about 7.8. 4 figures. 3 tables. 17 references.

Long-Term Management of Cirrhosis: Appropriate Supportive Care Is both Critical and Difficult Source: Postgraduate Medicine. 109(3): 101-118. March 2001. Contact: Available from McGraw-Hill, Inc. 1221 Avenue of the Americas, New York, NY 10020. (612) 832-7869. Summary: In the United States, about 26,000 of the 3 million people who have chronic liver disease die each year because of hepatic cirrhosis (liver scarring). Liver transplantation offers the best hope of survival for many of these patients, but the number of patients awaiting transplant far exceeds the number of organs available. This article (the last in a four part series on cirrhosis) offers a guide for primary care physicians who are caring for patients with chronic liver disease. The focus is on strategies to slow the course of liver disease and improve both the quality and length of life for these patients. The authors stress that early consultation with a liver transplant center can be helpful. The transplant hepatologist (liver specialist) and surgeon can help with triage decisions, guide workup, provide advice about patient care, optimize the timing of transplantation, offer specialized diagnostic and therapeutic options, and help the treating physician stay up to date on the continuous changes in this complex field. The authors offer a ten-point program for the comprehensive management of the patient with cirrhosis. The authors conclude that it is often the skill and diligence of the primary care physician in diagnosing liver disease, identifying and treating correctable causes, optimizing the patient's health and nutrition, and anticipating and preventing catastrophic complications that determine whether the patient lives or dies. Appended to the article is a lengthy list of resources on cirrhosis, including organizations, web sites, and publications, separated by those designed for physicians and those specifically for patients. 1 figure. 3 tables. 27 references.

Management of Primary Biliary Cirrhosis Source: Hepatology. 31(4): 1005-1013. April 2000. Contact: Available from W.B. Saunders Company. 6277 Sea Harbor Drive, Orlando, FL 19106-3399. (800) 654-2452 or (407) 345-4000. Summary: Primary biliary cirrhosis (PBC) is a presumed autoimmune disease of the liver, which predominantly affects women once over the age of 20 years. Most cases are diagnosed when asymptomatic (60 percent). This article offers guidelines to assist physicians in the recognition, diagnosis, and management of patients with PBC. The antimitochondrial antibody is present in serum (blood) in most, but not all, patients with PBC. The disease generally progresses slowly, but survival is less than an age and gender matched general population. The symptomatic patients may have fatigue, generalized pruritis (itching), portal hypertension (high blood pressure), osteoporosis, skin xanthomata (yellowish nodules), fat soluble vitamin deficiencies, and or recurrent asymptomatic urinary tract infections (UTI). Many non liver autoimmune diseases are
8
Cirrhosis
found in association with PBC and may prompt initial presentation. To date, immunosuppressive therapy has not been shown to prolong survival in PBC. The use of urodeoxycholic acid (UDCA) can delay the time to liver transplantation or death (typically given in a dose of 13 to 15 mg per kg daily). This therapy also causes a significant improvement of all the biochemical markers of cholestasis but has no beneficial effects on any of the symptoms or associated disorders. Treatment with UDCA does not obviate the need for liver transplantation. Therapies to prevent complications arising from malabsorption, portal hypertension, and or osteoporosis are required as well. Good control of pruritus can be achieved in most patients. PBC is diagnosed with increasing frequency, but the agent(s) responsible for this slowly progressive destruction of the bile ducts remains elusive and hence a specific therapy remains unavailable. 3 figures. 1 table. 105 references. •
Epidemiology and Natural History of Primary Biliary Cirrhosis in a U.S. Community Source: Gastroenterology. 119(6): 1631-1636. December 2000. Contact: Available from W.B. Saunders Company. 6277 Sea Harbor Drive, Orlando, FL 19106-3399. (800) 654-2452 or (407) 345-4000. Summary: Primary biliary cirrhosis is a chronic, cholestatic disorder characterized by progressive inflammation and destruction of the small bile ducts. The epidemiology of primary biliary cirrhosis (PBC) has not been studied systematically in the United States. In this article, the authors report the incidence (new cases) and prevalence (existing cases) of this condition in the general population. The authors also examine the validity of the Mayo natural history model for PBC among these unselected patients from the community. The cases were identified from the Rochester Epidemiology Project, which entails a computerized index of diagnoses from the health care encounters of residents of Olmsted County, Minnesota. The authors estimated the incidence and prevalence of PBC in this population and compared the actual survival of patients with PBC in the community with the survival predicted for PBC patients by the Mayo natural history model. The age adjusted (to 1990 U.S. whites) incidence of PBC per 100,000 person years was 4.5 for women, 0.7 for men, and 2.7 overall. The age and sex adjusted prevalence per 100,000 persons was 65.4 for women, 12.1 for men, and 40.2 overall. The authors conclude that the Mayo natural history model accurately predicted the actual survival of these patients. These results indicate that the incidence and prevalence in this country are among the highest reported. Outcomes among these unselected patients from a community population further validated the Mayo natural history model of PBC. 2 figures. 2 tables. 38 references.

(800) 654-2452 or (407) 345-4000. Summary: Sleep disturbance is a classic sign of hepatic encephalopathy, but there are limited data regarding its prevalence in patients who have liver cirrhosis without overt hepatic encephalopathy. This article reports on a study that assessed the characteristics of sleep in cirrhosis using a sleep questionnaire (n = 44) and actigraphy (n = 20). The results were compared with those of subjects with chronic renal failure and those of healthy controls. Presence of subclinical hepatic encephalopathy, chronotypology profile, and each individual's affective state were also analyzed. The questionnaire indicated that an elevated number of patients with cirrhosis (47.7 percent) and patients

with chronic renal failure (38.6 percent) complained of unsatisfactory sleep compared with healthy controls (4.5 percent). Actigraphy corroborated the deterioration of sleep parameters in cirrhotic patients with unsatisfactory sleep. The actigraph is a sensor that translates physical motion to a numeric representation. The sleep disturbance in cirrhosis was not associated with clinical parameters nor with cognitive impairment. Cirrhotic subjects and patients with chronic renal failure with unsatisfactory sleep showed higher scores for depression and anxiety, raising the possibility that the effects of chronic disease may underlie the pathogenesis of sleep disturbance. However, in contrast to chronic renal failure, unsatisfactory sleep in cirrhosis was associated with delayed bedtime, delayed wake-up time, and evening chronotypology. The authors conclude that sleep disturbance is frequent in patients with cirrhosis without hepatic encephalopathy and may be related to abnormalities of the circadian timekeeping system. 3 figures. 4 tables. 40 references.

Hepatic Encephalopathy: Metabolic Consequence of Cirrhosis Often is Reversible Source: Postgraduate Medicine. 109(2): 52-54, 57-60, 63-65, 69-70. February 2001. Contact: Available from McGraw-Hill, Inc. 1221 Avenue of the Americas, New York, NY 10020. (612) 832-7869. Summary: This article discusses hepatic encephalopathy, a condition characterized by neuropsychiatric manifestations ranging from a slightly altered mental status to coma, and neuromuscular symptoms may be present. This complication of chronic or acute liver disease is a result of the failure of the liver to detoxify toxins originating in the intestine. The pathogenesis (how it occurs) probably is multifactorial, although the predominant causative agent appears to be ammonia. About 30 percent of patients with cirrhosis (scarring of the liver) die in hepatic coma. The molecular basis of neurotoxicity of ammonia or other agents implicated in the condition is poorly understood. Therapy includes timely recognition and correction of precipitating factors. Once the condition is manifested, standard therapy is acute administration of lactulose, a disaccharide that is undigested in the small intestine. The beneficial action of lactulose is not fully understood. The use of oral antibiotics and BCAAs (branched chain amino acids) is of some benefit in patients who do not respond to lactulose. Limitation of protein in the diet may be useful for short periods but is not recommended for long term use because of potential worsening of already poor nutrition. The ultimate therapy for hepatic encephalopathy is orthotopic liver transplantation. Future research will likely focus on the correction of alterations in neurotransmission. 2 figures. 4 tables. 20 references.

High Prevalence of Celiac Sprue Among Patients with Primary Biliary Cirrhosis Source: Journal of Clinical Gastroenterology. 25(1): 328-329. July 1997. Contact: Available from Lippincott-Raven Publishers. P.O. Box 1550, Hagerstown, MD 21741. (800) 638-3030 or (301) 714-2300. Summary: This article explores the high prevalence of celiac sprue among patients with primary biliary cirrhosis (PBC). The authors note that, although coexisting PBC and celiac sprue have been described, celiac is sufficiently common in western Europe for chance to explain isolated cases. The authors screened their patients with PBC for celiac sprue by serum testing, with confirmation by duodenal biopsy. Of 57 patients, 6 (11 percent) tested positive. Four of these agreed to have a biopsy taken, and all had villous atrophy, yielding a minimum prevalence of 1 in 14 (7 percent). Apart from anemia in one patient, none of the four had symptoms or routine laboratory abnormalities suggestive of celiac sprue. None had improvement in liver biochemical tests after 12 to

24 months on gluten-free diets, despite the disappearance of the immune marker. The authors conclude that celiac sprue is common among patients with PBC and they should be routinely screened for this condition. Symptoms wrongly attributed to PBC may respond to gluten exclusion, and both conditions are potent risk factors for osteoporosis. 20 references. (AA-M). •

[email protected]. Summary: This article offers an update on primary biliary cirrhosis (PBC), a chronic inflammatory condition of the liver characterized by generalized pruritis (itching), enlargement and hardening of the liver, fatigue, weight loss, and diarrhea with pale, bulky stools. The diagnosis of PBC is most often made in the asymptomatic phase, sometimes before the development of abnormal liver biochemistry. The antimitochondrial antibody remains the predominant hallmark. The etiology (cause) of PBC remains elusive; studies suggest that the interlobular bile duct destruction is immune based, and associated autoimmune diseases are common. There are no markers that predict outcome in asymptomatic patients, whose chance of survival is less than that of age and sex matched populations, but much better than the median survival of eight years in patients with symptomatic PBC. Symptoms common in this disease include fatigue, pruritis, and xanthelasma (soft yellow spots or plaque occurring on the eyelids), as well as complications of portal hypertension (high blood pressure) and osteoporosis. Treatment includes symptomatic and preventive measures, as well as specific therapeutic measures. Immunosuppressive therapy has yielded disappointing results in the long term management of PBC, and the only therapy shown to improve survival in the hydrophobic dihydroxy bile acid, urosdeoxycholic acid. Treatment at a dose of 13 to 15 milligrams per kilogram of body weight per day is optimal, given in separate doses or as a single dose at least 4 hours from giving the oral anion exchange resin cholestyramine, which may be used to control pruritis. However, liver transplantation remains the only cure for this disease. Recurrence after transplantation takes place but is rarely symptomatic and does not deter from the benefits of transplantation. 55 references.

Treatment of Patients with Hepatitis C and Cirrhosis Source: Hepatology. 36(5 Supplemental 1): S185-S194. November 2002. Contact: Available from W.B. Saunders Company. 6277 Sea Harbor Drive, Orlando, FL 19106-3399. (800) 654-2452 or (407) 345-4000. Summary: This article offers guidelines for the treatment of patients with hepatitis C and cirrhosis (scarring of the liver). The author notes that determining recommendations for this patient population is difficult. Few prospective studies have focused on the treatment of patients with advanced disease, and response rates appear to be lower and serious side effects more frequent in patients with cirrhosis. In patients with compensated cirrhosis, combination therapy with interferon alfa and ribavirin results in a sustained virological response (SVR) in 33 to 41 percent of patients. Responses to combination therapy are not significantly higher using peginterferon alfa 1a or 2b, compared with standard interferon. In using peginterferon in combination therapy, the benefits of once weekly dosing need to be weighed against the higher risks of cytopenias and greater costs with the pegylated formulations. Combination therapy results in some

degree of histological improvement even in patients who are virological nonresponders. These findings provide the scientific basis for ongoing studies of maintenance therapy with peginterferon to prevent complications of cirrhosis in nonresponders patients with hepatitis C. Recommendations for the management of decompensated cirrhosis and of recurrent hepatitis C after liver transplantation are difficult because of limitations of data, most of which are derived from uncontrolled case series. Combination therapy is poorly tolerated in both groups and rates of response are low. Thus, while the medical need is great, treatment of patients with decompensated cirrhosis or with recurrent hepatitis C after transplantation should be undertaken cautiously and only within the confines of prospective clinical trials. 2 figures. 1 table. 16 references. •

AJN, P.O. Box 50480, Boulder, CO 80322-0480. (800) 627-0484 or (303) 604-1464. Summary: This article provides nurses with an overview of primary biliary cirrhosis (PBC), a slowly progressive chronic liver disease that causes inflammatory destruction of the bile ducts, bile acid buildup, cirrhosis, and ultimately liver failure. The etiology of PBC is unknown, but it is suspected to be an autoimmune disorder. Many patients with PBC are asymptomatic; intense pruritis (itching) is commonly the presenting symptom. Patients may also report painful joints or bones, indigestion or nausea, persistent abdominal ache in the upper right quadrant, and fluid retention. Dark urine, pale stools, easy bruising or bleeding, esophageal varices, increased skin pigmentation, and jaundice mark late stage disease. Diagnosis is confirmed by liver biopsy. Treatment with ursodeoxycholic acid may slow progression of the disease; other interventions focus on increasing quality of life and delaying the need for liver transplant. The author concludes by reviewing patient education strategies for patients with PBC. 1 figure.

Summary: This article reports on a study that assessed the effects of chronic hepatitis C virus (HCV) infection, in the absence of cirrhosis (liver scarring), on patients quality of life (QOL). Assessment was done by using the short form 36 (SF36) symptomatology questionnaire. Patients with chronic hepatitis C were polysymptomatic (had many symptoms) and had significant reductions in their SF36 scores for all of the modalities tested. By contrast, patients with chronic hepatitis B virus (HBV) infection showed a reduction in the SF36 scores that assessed mental function, but no decrease in the scores that measured physical symptoms, indicating that the symptoms associated with chronic HCV infection are qualitatively different from those associated with chronic HBV. Patients with chronic HCV infection who had used intravenous drugs in the past had the greatest impairment in QOL scores, but the reduction was found even in patients who had never used drugs. The reduction in QOL could not be attributed to the degree of liver inflammation or to the way the infection was acquired. The authors conclude that chronic infection with HCV per se gives rise to physical symptoms that reduce the QOL of those who have it. 2 figures. 1 table. 13 references. (AA-M). •

[email protected]. Website: www.blackwell-science.com. Summary: This article reports on a study undertaken to investigate the prevalence and clinical significance of hepatitis C virus (HCV) infection and its relationship with the development of hepatocellular carcinoma (HCC, liver cancer). In the study, 162 consecutive alcoholic Korean patients with cirrhosis were studied. Alcohol intake and parenteral risk factors were investigated by interview using a questionnaire. All patients had consumed at least 80 grams of alcohol per day for at least the past 5 years. Patients were categorized into 3 groups: anti HCV or HBsAg (group A); cases with HBsAg only (group B), and cases with anti HCV only (group C). Anti-HCV was present in 17 cases (10.5 percent) and HBsAg was present in 47 cases (29 percent). No patient had both antiHCV and HBsAg. Group C subjects were the oldest, but the duration of drinking in this group was similar to that of group A. There was no significant difference in the daily alcohol intake among the three groups of patients. Previous surgical operations and tattooing were more frequent in group C. Only one patient in group C was an intravenous drug user. The combined rate of HCC was significantly higher in groups B and C than in group A (34 percent, 23.5 percent, and 6.1 percent, respectively). Laboratory data showed a higher platelet count, higher albumin level, lower bilirubin lever. and lower aspartate amino transferase or alanine aminotransferase ratio in group C patients than in the other two groups. The authors conclude that hepatitis C virus infection is frequent in alcoholic patients with cirrhosis in Korea. Hepatitis C virus, as well as hepatitis B virus, infection may have a synergistic effect on the development of HCC in alcoholic patients. 1 figure. 3 tables. 28 references.

Summary: This article reviews type 1 hepatorenal syndrome (HRS), a severe complication of end-stage cirrhosis (liver scarring). Type 1 HRS is an acute functional renal failure (i.e. glomerular hypofiltration) with no other explanation than the presence of the circulatory and neurohumoral alterations associated with severe chronic liver disease. Plasma volume expansion does not improve renal (kidney) function. In contrast, administration of the vasopressin analog terlipressin, a splanchnic and systemic vasoconstrictor, may improve renal function and be used while awaiting liver transplantation. 3 figures. 3 tables. 63 references. •
Higher Dose and Longer Duration of Interferon Alpha-2a Reduced the Incidence of Cirrhosis in Chronic Hepatitis C (commentary) Source: ACP Journal Club. 130(2): 37. March-April 1999. Contact: Available from American College of Physicians-American Society of Internal Medicine (ACP-ASIM). 190 North Independence Mall West, Philadelphia, PA 191061572. Summary: This brief article offers a summary of a recent research study, with an accompanying commentary. The study was undertaken to measure whether an increased dose and longer duration of interferon alfa 1a (INF) therapy is more effective in patients with chronic hepatitis C than standard doses for preventing the development of cirrhosis. The study comprised 244 patients (mean age 37 years, 64 percent men) with confirmed hepatitis C. Of these, 124 patients were allocated to the reinforced regimen, and 120 to the standard regimen. Patients in the reinforced group had a higher rate of maintaining normal levels of alanine transaminase (ALT), undetectable HCV levels, and a lower incidence of cirrhosis than patients in the standard group. Patients in the reinforced group also had higher rates of flulike syndrome (68 percent versus 54 percent), nausea or vomiting (60 percent versus 38 percent), and weight loss (96 percent versus 81 percent), but not thyroiditis, suicide attempts, or irritability. In the commentary, the author notes that the lower frequency of cirrhosis in the reinforced therapy group is curious and that lack of the standard 12 month duration of treatment for the control group makes interpretation of the results difficult. As expected, most patients in the reinforced group experienced more side effects than controls, but only a few withdrew from the study, generally confirming the high motivation of these patients to pursue treatment for this recalcitrant disease. 1 table. 2 references.

Treatment of Primary Biliary Cirrhosis: Review Source: Journal of Gastroenterology and Hepatology. 11(7): 605-609. July 1996. Summary: This review article covers the treatment of primary biliary cirrhosis (PBC), a slowly progressive chronic cholestatic disease of the liver thought to be caused by immune destruction of the interlobular bile ducts. Therapeutic regimens should aim to control symptoms, prevent complications, and control disease progression. Preventative therapy includes regular screening for thyroid dysfunction and replacement therapy when necessary, and administration of the fat soluble vitamins A, D, and K for hyperbilirubinemia. Esophageal varices may develop early in the course of PBC; nonselective beta blocker therapy should be used as prophylaxis against variceal hemorrhage. The only specific therapy shown to benefit patients with PBC is ursodeoxycholic acid (UDCA). Treatment with UDCA delays disease progression, but does not result in a cure. Currently, liver transplantation is the only definitive treatment available for end stage disease. 29 references. (AA-M).

Ursodeoxycholic Acid in Primary Biliary Cirrhosis: A Review Source: Practical Gastroenterology. 19(2): 23, 24, 26. February 1995. Summary: This review article explores the use of ursodeoxycholic acid (UDCA) in the treatment of primary biliary cirrhosis (PBC). The author reviews the experimental evidence that points to several possible mechanisms for the beneficial action of this agent, including displacement of more toxic endogenous bile acids, immunomodulation, and induction of choleresis producing increased excretion of toxic compounds. The author notes that several biochemical markers have been evaluated for their potential usefulness in assessing prognosis and response to therapy, but none has yet been shown to be clearly reliable. Trial results suggest that UDCA is not effective in late-stage disease and may even induce hepatic decompensation; therefore, early diagnosis and intervention are crucial. 13 references. (AA-M).

[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.

concerns. This article reports on a study undertaken to determine the cost effectiveness of UDCA in PBC. The authors compared the costs and outcomes of managing PBC in patients with and without UDCA. From two previously published trials, the effectiveness of UDCA was determined by comparing the annual reduction in the development of ascites, varices, variceal bleeding, encephalopathy, liver transplantation, and death between the treatment groups. Average annual costs for each of these events were estimated from the literature and from institutional data. Approximately twice as many major events occurred in the placebo group as in the UDCA group. The relative risk of liver transplantation and of development of esophageal varices was significantly higher in the placebo group than in the UDCA group. There were no significant increases in the of ascites, variceal bleeding, encephalopathy, or death between the two groups. On the basis of the estimated annual cost of managing these events and the annual cost of UDCA ($2,500), there was an annual cost savings per patient of $1,372. Compared with the placebo group, patients receiving UDCA had a lower incidence of major complications and lower medical care costs. 6 figures. 5 tables. 21 references. (AAM).

temporarily depleted of CD8+ T cells prior to challenge with HCV. This experimental approach will address the following aims: 1) To assess how HCV replication and liver pathology is altered by depletion of CD8+ T cells prior to infection, 2) To study the evolution of the CD4+ T cell response to acute HCV infection during the absence and recovery of the CD8+ T cell compartment, and 3) To determine if eliminating the selective pressure mediated by CDS+ T cells alters the evolution of class I and class II MHC restricted HCV epitopes. Results from the experiments proposed in this research plan should contribute to our understanding of HCV pathogenesis by providing a detailed temporal analysis of the kinetics of viral replication and liver pathology during the absence and recovery of the CDS+ T cell compartment following HCV infection. These studies will also provide important new information as to the relative importance of CD8+ and CD4+ T cell responses in the control of HCV infection while determining if a correlation exists between the emergence of antigen specific T cells, the evolution of escape mutations, and the kinetics of virus replication in vivo.

The long-term objective for the proposed research is the discovery of effective and safe anti-fibrotic agents for treating liver fibrosis and thereby decreasing the risk of cirrhosis in individuals with liver disease. Activation and trans-differentiation of the hepatic stellate cell (HSC) into the collagen-forming myofibroblast are key events involved in liver fibrosis. We, and others, have shown that stimulation of adenosine receptors on other matrix forming cells leads to inhibition of activation, proliferation, and synthesis of connective tissue proteins. We propose that inhibition/ reversal of HSC activation in fibrosis can be achieved through stimulation of adenosine receptors on HSCs. The research plan includes the use of various subtype specific adenosine receptor agonists, antagonists, and agents that modulate adenosine metabolism and biosynthesis. Using these biological tools and other molecular probes, all available at Metabasis Therapeutics, rat HSCs will be studied in order to confirm the presence of adenosine receptors and probe their function. After identification of the subtype, the concept will be tested using an in-vivo model of fibrosis. PROPOSED COMMERCIAL APPLICATIONS: Given the worldwide increase in liver disease resulting in hepatic fibrosis/ cirrhosis, and the current lack of proven therapies, the medical need and potential market for a therapeutic to treat hepatic fibrosis are large. The research in this proposal will provide the scientific and commercial foundation to support the development of a novel small- molecule therapeutic for the treatment of hepatic fibrosis/cirrhosis.

Summary: (provided by applicant):Over the past decade a growing shortage of donated organs has greatly increased the number of patients who have developed complications of end-stage cirrhosis including hepatocellular carcinoma (HCC) and the mortality for patients awaiting liver transplantation (LT). Living donor liver transplantation (LDLT) was conceived as a way to increase the availability of donated organs and was initiated in infants and children more than a decade ago. Controlled trials demonstrated the safety and efficacy of this procedure. Recently, LDLT has been adapted for the adult. Since then patients, their families and the transplant community have embraced this procedure despite reports of donor morbidity, mortality and early reports that recipients may have increased post-operative complications and reduced survival compared to CADLT. The specific aims of the LDLT cohort study is to define the short and long term risks of morbidity and mortality for the adult donor and to determine the efficacy of this procedure for the adult recipient compared to patients undergoing LT with a cadaveric liver (CADLT). Individuals interested in becoming living donors will be asked to participate in this study. Those who are selected and undergo the surgical procedure will be followed at periodic intervals to define the long term morbidity and mortality of the procedure. Individuals not selected as living donors will be matched to the actual donors 2:1 by age, race and gender and also followed prospectively as a donor control group. Individuals being evaluated for LT will be asked if they would be interested in undergoing LDLT. Those patients who identify an acceptable donor and undergo LDLT will be followed prospectively at periodic intervals to define the short and long term morbidity and mortality associated with this procedure. Those patients who are unable to identify a living donor will be matched to an actual LDLT recipient 2:1 by age, race, gender, disease etiology and severity of liver disease (MELD score). These patients will act as the recipient control group and will and be followed prospectively before and after they undergo CADLT. Ancillary studies accompanying the main trial will specifically evaluate the ability of LDLT to improve the long term outcome of patients with HCC and to evaluate the effects of donation and LDLT on hepatic histology.

Project Title: ALCOHOL AND HIV PROTEASE INHIBITORS INTERACTIONS Principal Investigator & Institution: Feierman, Dennis E.; Anesthesiology; Mount Sinai School of Medicine of Nyu of New York University New York, Ny 10029 Timing: Fiscal Year 2002; Project Start 30-SEP-2002; Project End 31-AUG-2004 Summary: (provided by applicant): There is great interest and possible concern in the use of ethanol by HIV infected patients. Ethanol has been shown to induce cytochrome P450 (CYP) 3A, an isoform responsible for the metabolism of HIV PIs (HIV-PIs). The goal of this proposal is to evaluate the effects of ethanol consumption on the pharmacokinetics, specifically AUC and Cmax, of orally administered HIV-protease inhibitors. Two specific objectives are derived from this goal and are addressed in this application that will utilize two rodent models of ethanol consumption and its interaction on drug disposition.S.A.I: To characterize the pharmacokinetics of orally administered HIV protease inhibitors in rats fed the Leiber-DeCarli ethanol-containing diet, and pair fed and ad-lib controls. This model was chosen since it has been shown that ethanol can induce CYP3A without significant liver pathology and may be analogous to early alcohol disease. S.A.II: To characterize the pharmacokinetics of orally administered HIV protease inhibitors in rats fed ethanol and liquid diet via the intragastric tube feeding method. This model of ethanol consumption was chosen since it has been shown to be a better inducer of CYP3A and also cause substantial liver pathology.1) Characterize and compare the pharmacokinetics of select HIV protease

inhibitors (HIV-PI) such as saquinavir and indinavir after their oral administration in these models (and controls) chronically fed ethanol. We will also ascertain the effects of pretreatment with triacetyloleandomycin (TAO), a specific inhibitor of CYP3A, on the pharmacokinetics of rally administered saquinavir and indinavir.2) Characterize and compare the pharmacokinetics of saquinavir and indinavir after oral co-administration with ethanol in these models.3) Validate the induction of CYP3A activity, content and specific inhibition of CYP3A by TAO in liver and small bowel in these rats. Since paraglycoprotein (pgp) can affect the bioavailability of HIV protease inhibitors we will also characterize the effects of chronic ethanol on pgp content.The success of antiretroviral medication therapies for the treatment of HIV-disease is now well documented. These benefits are only tenable when therapeutic levels of the antiviral treatments are maintained. Understanding drug interactions and induction of HIV-PI metabolism remains a critical goal for those individuals receiving treatment. Many individuals taking these medications also consume ethanol, acutely and chronically. Because of the importance of CYP3A4 with respect to HIV-PI drug metabolism, and its induction by ethanol, the interactions of HIV-PI and ethanol are of clinical importance and are the major focus of this proposal.

Project Title: ALCOHOL AS A MODULATOR OF PREFIBROTIC LIVER INJURY Principal Investigator & Institution: Clemens, Mark G.; Professor and Chair; Biology; University of North Carolina Charlotte Office of Research Services Charlotte, Nc 282230001 Timing: Fiscal Year 2001; Project Start 01-AUG-2001; Project End 31-JUL-2003 Summary: Alcohol is implicated as the etiologic agent in greater than 50% of deaths due to liver cirrhosis, a growing national health concern. It is widely accepted that ethanolinduced oxidative injury can result in inflammation, steatohepatitis, hepatocellular carcinoma and fibrosis. However, it is unknown why only a subpopulation of alcoholic liver disease patients present with end stage liver cirrhosis. Likewise, factors contributing to increased obesity-related susceptibility to the deleterious effects of ethanol are poorly understood. This NIAAA R03 has as its primary focus to achieve a basic understanding of whether differences in the severity of alcoholic liver disease can be explained, in part, by alcoholinduced acceleration of preexisting liver injury. This proposal builds on our recent observation that combined hyperlipidemic mice that overexpress apolipoprotein C-I maintained on a chow diet develop prefibrotic liver injury. The hypothesis that will be tested is that alcohol can exacerbate preexisting liver injury initiated by chronic hyperlipidemia. In this study, normolipidemic and hyperlipidemic mice fed alcohol or a control diet will be evaluated for changes in plasma lipids and lipoproteins. Intravital microscopy will be used to monitor liver microcirculation, tissue damage and collagen deposition. Tissue evaluation will indicate the metabolic health and extent of liver injury. This study is of immediate interest because while hyperlipidemia is pandemic in the US, the observation that chronic hyperlipidemia can result in liver injury was previously unappreciated. With our recent observation that chronic hyperlipidemia can result in liver injury we will determine whether alcohol can accelerate the development of liver disease in a spontaneous liver injury model where the damage is initiated by preexisting hyperlipidemia.

Project Title: ALCOHOL IN MEXICAN-ORIGIN GROUPS: US AND MEXICAN SURVEYS Principal Investigator & Institution: Greenfield, Thomas K.; Center Director and Senior Scientist; Public Health Institute 555 12Th St, 10Th Fl Oakland, Ca 94607 Timing: Fiscal Year 2002; Project Start 01-AUG-2002; Project End 31-JUL-2005 Summary: (provided by applicant): Based on the 2000 census, over 32.8 million Hispanics in the US represent 12% of the county's total population. People of Mexican origin constitute the largest, fastest growing subgroup. They are now two-thirds of all US Hispanics, and this subgroup has grown 53% since 1990. Numerous indicators show that such alcohol-related problems as alcohol dependence and such adverse social and health consequences as cirrhosis disproportionately affect Mexican Americans- health disparities that NIAAA is committed to addressing. This research will conduct a secondary analysis of three datasets, two drawn from existing Alcohol Research Group US National Alcohol Surveys (NASs), each including large Hispanic oversamples, and the 1998 Mexican National Survey of Addictions (ENA) conducted by our collaborators at the National Institute of Psychiatry, Mexico City. Questionnaires for the ENA (n = approximately 5,712) used NAS alcohol items and scales, so assuring considerable comparability. The US surveys were conducted in 1995 (N9) as face-to-face interviews (n = 4,925; 1,589 Hispanics; 964 of Mexican descent), and in 2000 (N10+Supplement) as telephone surveys (n = 8,980; 1,132 Hispanics; est. 679 of Mexican descent) of adults 18 or older. Following preliminary analyses, we plan to pool the Mexican-descent NAS samples, limiting age range to 18-65 (pooled n = 1,542) for comparison with the ENA. Specific Aims include (1) comparing and contrasting the prevalence, predictors and correlates of heavy drinking, alcohol use disorders (AUD), and other alcohol-related problems among men and women of Mexican descent living in the two countries (US and Mexico); (2) analyzing and comparing the comorbidity of AUD and drug abuse, and AUD and depression, among these groups; (3) investigating the risk curves between key parameters of drinking pattern (volume and frequency of heavy drinking) and AUD and a range of alcohol-related health and social harms in the two Mexican- origin populations, considering the role of demographic mediators such as gender, age and (for the US) acculturation; and (4) exploring the association of alcohol treatment in relation to AUD and other alcohol-related problems, health harms, drug abuse, and depression among Mexican Americans in the US. This research accords with the NIAAA strategic action plan for addressing health disparities: using a rigorous study design, it aims to provide critically needed knowledge in detail about drinking patterns and alcohol-related consequences of a key ethnic minority population-Mexican descent Hispanic individuals-known to be at risk for alcohol dependence and other health harms from drinking. Results will inform provision of culturally appropriate health services and prevention program planning. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen

Project Title: ALCOHOL REDUCTION IN MEDICAL ILLNESSES:HCV AS PROTOTYPE Principal Investigator & Institution: Dawson, Neal V.; Medicine; Case Western Reserve University 10900 Euclid Ave Cleveland, Oh 44106 Timing: Fiscal Year 2002; Project Start 30-SEP-2002; Project End 31-AUG-2007 Summary: (provided by applicant): Alcohol use is discouraged or contraindicated for patients with a variety of medical illnesses. For many diseases directly caused by alcohol, the use of alcohol may be associated with recurrent symptoms shortly after its
20
Cirrhosis
consumption, e.g., pancreatitis or gastritis, and the prohibition against alcohol is straightforward. However, for many chronic diseases, the use of alcohol is not associated with any short-term symptoms or sequelae. The course of these chronic diseases (or their treatments) among non-abusing/nondependent patients can be adversely affected by even moderate alcohol use, e.g., chronic hepatitis, (nonalcoholic) cirrhosis, severe diabetes, or the use of the 'blood thinner', warfarin. Chronic Hepatitis C virus (HCV) infection is a prototypical example of a disease in which alcohol use tends to cause no symptoms. Even moderate chronic alcohol use can be associated with an increased likelihood of cirrhosis and liver cancer. HCV infection rates and prognosis are related to alcohol use in multiple ways. Alcohol use during HCV treatment is associated with a decreased likelihood of viral clearance. Long-term alcohol use may increase the proliferation of HCV and the associated liver damage even with moderate alcohol consumption. Greatly reducing or eliminating alcohol use may importantly enhance the prognoses of patients, even if they are not candidates for specific HCV treatments. Despite having diagnoses that warrant abstinence from alcohol, many patients continue to drink alcohol. Little is known about why patients continue to consume alcohol in the face of diagnoses that warrant a reduction in use or abstinence. The current study is designed to determine factors that lead to continuing alcohol intake among alcohol nonabusing/nondependent patients who are advised to stop drinking by health care providers. In Phase 1, focus groups (patients and providers) will be used to discover issues that may be associated with continued drinking. In Phase 2, questionnaire items will be developed based on the data gleaned from Phase 1. The potential pool of items will be administered to 10 patients per item and factor analyzed. In Phase 3, the items retained from the pool of potential items will be used to create a questionnaire that will be tested for its ability to predict alcohol reduction or cessation. Since alcohol use is common in the U.S. and since most patients who currently have HCV are not candidates for treatment, abstinence from alcohol use represents a major opportunity to prevent a decline in the health and quality of life of patients with HCV and similar diseases.

Project Title: ALCOHOL/CELLULAR IMMUNITY IN HCV AND HIV INFECTION Principal Investigator & Institution: Chang, Kyong-Mi M.; Assistant Professor; Medicine; University of Pennsylvania 3451 Walnut Street Philadelphia, Pa 19104 Timing: Fiscal Year 2001; Project Start 28-SEP-2000; Project End 31-JUL-2005 Summary: Up to 3% of the world population is infected with hepatitis C virus (HCV), a hepatotropic RNA virus that causes acute and chronic hepatitis as well as cirrhosis and hepatocellular carcinoma. HCV infection results in chronicity in most cases (85%) despite detectable antiviral immune response, and recent studies suggest that virusspecific T cells play an important role in the outcome of HCV infection. Interestingly, HCV infection is up to 7 fold more prevalent in alcoholic individuals than in the general population, and chronic alcohol use in HCV-infected patients is associated with accelerated liver disease progression and development of liver cancer. While alcohol is known to suppress cellular immune response, little is known about the effect of alcohol on HCV-specific T cell response in HCV-infected patients. Therefore, the primary aim of this application is to determine if chronic alcohol use results in a pathogenetic HCVspecific T cell response that promotes further liver damage than virus control. In addition, we will determine the extent to which this may be reversed upon alcohol cessation. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen

Project Title: ALCOHOLISM & LUNG INJURY--CIRRHOSIS & GLUTATHIONE DEF Principal Investigator & Institution: Moss, Marc Marc.; Assistant Professor; Internal Medicine; Emory University 1784 North Decatur Road Atlanta, Ga 30322 Timing: Fiscal Year 2001; Project Start 01-SEP-2000; Project End 31-AUG-2003 Summary: The acute respiratory distress syndrome (ARDS) is a severe form of acute edematous lung injury that afflicts approximately 150,000 individuals per year in the United States. Despite three decades of research concerning ARDS, there are presently no effective therapies and the mortality from this syndrome remains unacceptably high at 40-60 percent. The ability of the lung to neutralize the harmful effects of oxygen radicals has been postulated to be a critical step in preventing the development and decreasing the severity of ARDS. Initially, we hypothesized that the presence of preexisting co-morbid conditions, which independently reduce the anti-oxidant capacity of the lung, will result in an increased incidence and severity of ARDS in critically ill patients. We have previously reported that chronic alcohol abuse, without hepatic dysfunction, decreases pulmonary glutathione concentrations and alters surfactant function in both animals and humans, and increases the incidence and severity of ARDS in critically ill patients. Based on the profound effects of chronic hepatic dysfunction on systemic glutathione homeostasis, we hypothesize that cirrhosis secondary to chronic alcohol abuse will lead to a dramatic reduction in pulmonary glutathione reserve with subsequent impairment of surfactant function, thereby markedly increasing the risk of critically ill cirrhotic patients to develop ARDS. In this first part of this proposal, we will determine lung lavage glutathione concentrations and surfactant properties in control subjects and patients with clinically stable cirrhosis. In the second part of the proposal, we will examine how cirrhosis alters the pulmonary response to sepsis. Finally, we will further explore the epidemiological association between cirrhosis and ARDS using a large national database. The results of these studies will create a strong foundation of evidence supporting the potential use of glutathione replacement therapy to decrease lung injury in patients with cirrhosis secondary to alcohol abuse.

Project Title: ALCOHOLISM:ALTERED ALVEOLAR MATRIX AND ACUTE LUNG INJURY Principal Investigator & Institution: Brown, Lou Ann S.; Professor; Pediatrics; Emory University 1784 North Decatur Road Atlanta, Ga 30322 Timing: Fiscal Year 2001; Project Start 30-SEP-2000; Project End 31-JUL-2004 Summary: (Adapted from Applicant's Abstract): Acute Respiratory Distress Syndrome (ARDS) is a common and severe form of acute lung injury that is associated with mortality of approximately 50 percent. A prospective study of 351 critically ill patients recently identified a history of chronic alcohol abuse with an increased incidence and severity of ARDS, regardless of the at-risk diagnosis. This observation identifies chronic alcohol abuse as the first reported comorbid variable that significantly increases the patient's risk of developing ARDS. Glutathione (GSH) is an essential component of the pulmonary antioxidant system and decreased GSH in the epithelial lining fluid has been associated with ARDS. Studies in the investigator's laboratory demonstrated that alcoholic adults without cirrhosis have and 80 percent decrease in GSH in the epithelial lining fluid, possibly due to decreased GSH availability from plasma. In a rat model of chronic ethanol ingestion, decreased GSH in the epithelial lining fluid and alveolar type II cells was associated with increased susceptibility to sepis-mediated acute lung injury.
22
Cirrhosis
The mechanisms by which ethanol-induced GSH depletion increases susceptibility to acute lung injury is the focus of this application. One hallmark of ARDS is altered alveolar matrix homeostasis as characterized by excessive alveolar matrix deposition and matrix turnover. Studies in the investigator's laboratory have demonstrated that in the rat model, ethanol-induced GSH depletion was associated with alveolar type II cells that produce an altered, unstable extracellular matrix that was unable to support type II cell functions. When sepsis was superimposed on ethanol ingestion, the lavage fluid had greater gelatinase activity. Prevention of many of these altered parameters with GSH precursors indicates the central role of GSH depletion in the process. This lead to the following hypothesis: chronic ethanol ingestion predisposes to acute lung injury by decreasing alveolar GSH which subsequently alters the homeostasis of the alveolar epithelial extracellular matrix. In the first three aims, the investigators will use the rat model of chronic ethanol ingestion to determine if ethanol predisposes to acute lung injury via altered matrix homeostasis (Aim1), if sepsis potentiates the ethanol-induced effects on matrix homeostasis (Aim 2) and if GSH availability mediates these effects on matrix homeostasis (Aim3).

Project Title: ANTIVIRAL & ANTIFIBROTIC LIVER THERAPY OF HCV+ DRINKERS Principal Investigator & Institution: Lieber, Charles S.; Professor of Medicine & Pathology; None; Mount Sinai School of Medicine of Nyu of New York University New York, Ny 10029 Timing: Fiscal Year 2001; Project Start 01-SEP-2000; Project End 31-MAY-2005 Summary: We plan to evaluate a combined antiviral, antifibrotic and antioxidant treatment in the progression of liver disease of heretofore excluded patients with hepatitis C namely alcohol drinkers. Abstainers or alcohol consumers will be given state- of-the-art antiviral treatment (pegylated interferon + ribavirin) for 24-48 weeks. Another innovative aspect of this proposal is the supplemention with an anti-fibrotic agent, namely polyenylphosphatidylcholine (PPC) extracted from soybeans, or placebo, administered for 3 years (concomitantly with the antiviral treatment and thereafter). Current therapy neglects the fact that what causes the major medical symptoms and eventually the demise of the patient is liver fibrosis, resulting cirrhosis and associated complications, including hepatocellular carcinoma. If the fibrotic process could be stopped or even prevented, the hepatitis C virus would lose much of its impact on health. Available anti-fibrotic agents are too toxic to be used in patients, except for one, namely PPC, which has been shown in various experimental models to have striking anti-fibrotic actions, and which was found recently to be beneficial in HCV+ patients in terms of their circulating levels of transaminases. Fibrosis was not assessed, but documentation of the effects of PPC on fibrosis in HCV+ patients is being proposed here. It is noteworthy that PPC was discovered to have also significant anti- oxidant effects. This may be important in HCV+ patients since various studies have now indicated that HCV is associated with an oxidative stress. Another innovative aspect is the inclusion of drinkers who thus far were excluded from standard antiviral treatment, mainly because of concerns about exacerbation of mental disorders, reliability and compliance. However, the latter objection has now been overcome by the availability of pegylated interferon which can be administered once a week by the therapist in a controlled fashion. For both PPC and ribavirin, compliance will be monitored by incorporation of markers, such as riboflavin, that can be measured in the urine. Spot checks of blood levels of dilinoleoylphosphatidylcholine (DLPC, the main

phosphatidylcholine species of PPC) will also be performed. Accordingly, support is requested for a a double-blind, randomized placebo controlled study to assess the efficacy of this novel approach for the treatment of liver disease in HCV+ alcohol consumers or abstainers. Funds are requested for special laboratory tests, study nurses, travel to meetings, patient monitoring expenses and a core office.

Project Title: AQUAPORIN-2 EXCRETION IN DISORDERS OF WATER BALANCE Principal Investigator & Institution: Cadnapaphornchai, Melissa A.; Pediatrics; University of Colorado Hlth Sciences Ctr P.O. Box 6508, Grants and Contracts Aurora, Co 800450508 Timing: Fiscal Year 2001; Project Start 30-SEP-2000; Project End 31-JUL-2005 Summary: (adapted from the application) Normal water metabolism is essential to body fluid homeostasis. The major determinants of normal water balance include arginine vasopressin (AVP), renal function, and thirst. Recent investigations have described the cloning and characterization of the water channel aquaporin-2 (AQP-2), which is located in the principal cell of the kidney collecting duct. Under the influence of AVP, AQP-2 inserts into the apical membrane, allowing reabsorption of water to occur. Studies in animals and humans suggest that alterations in the regulation and expression of AQP-2 in certain physiologic and pathologic states may contribute to such complications as hyponatremia, hypoosmolality, and edema. During exocytic shuttling of AQP-2 to the apical collecting duct membrane, a small percentage of AQP-2 is lost in the urine. Measurement of this urinary AQP-2 protein can be reliably performed by radioimmunoassay; this test represents a novel tool for evaluation of AVP action in the collecting duct of the human kidney in health and disease. In these studies, we will examine urinary AQP-2 excretion in patients during pregnancy and the menstrual cycle, and in patients with congestive heart failure, cirrhosis, nephrotic syndrome, and acquired nephrogenic diabetes insipidus due to lithium therapy or autosomal dominant polycystic kidney disease. An interpretation of the relationship between urinary AQP-2, serum and urine osmolality, and plasma AVP will provide insight into the control of body fluid homeostasis. The role of the vasopressin V2 receptor antagonist, CIPC-41061, in the treatment of volume overload, edema, and hyponatremia will be explored. A comprehensive understanding of AQP-2 regulation in humans will lead to unique and more direct interventions in the therapy of disordered water metabolism.

Project Title: AUTOANTIGEN ARRAYS TO SELECT VACCINES FOR MODEL OF PBC Principal Investigator & Institution: Utz, Paul J.; Medicine; Stanford University Stanford, Ca 94305 Timing: Fiscal Year 2002; Project Start 23-SEP-2002; Project End 31-MAY-2004 Summary: (provided by applicant): The broad, long-term objective of this proposal is to use autoantibody profiling to guide the selection of DNA tolerizing vaccines for the treatment of an animal model of primary biliary cirrhosis (PBC) called experimental autoimmune cholangitis (EAC). We will test the hypothesis that large-scale, parallel detection of autoantibody profiles can be used to explore epitope spreading, the role played by a subset of inflammatory cytokines in the initiation and propagation of autoimmunity, and ultimately in selection of antigen-specific tolerizing therapies. We will use biochemical, immunological, and molecular biological techniques to validate
24
Cirrhosis
and extend our ongoing protein array platform in exploring three specific aims in this proposal: (i.) to construct a PBC autoantigen microarray suitable for the identification of human and murine autoantibodies. This array will be used to identify dominant B cell epitopes in the EAC model, and to determine the precise ordering of epitope spreading in EAC. (ii.) to determine whether interleukin-4 (IL-4) and interferon-gamma (IFNy) are required for the development of EAC. An imbalance between Thl and Th2 lymphocytes is thought to play an important role in some autoimmune diseases, and IL-4 and IFN3' represent critical cytokines in the pathogenesis of autoimmunity. (iii.) to employ DNA vaccination to prevent and treat EAC using cDNAs encoding autoantigens identified using protein microarrays developed in the first aim. The results of this proposal will determine the long-term usefulness of the newly described EAC animal model of PBC. Successful treatment of EAC using plasmids encoding prominent autoantigens may herald an era of customized, antigen- or tissue- specific tolerizing therapy in humans.

Project Title: AUTOIMMUNITY CENTERS OF EXCELLENCE Principal Investigator & Institution: Chess, Leonard; Professor; Medicine; Columbia University Health Sciences New York, Ny 10032 Timing: Fiscal Year 2003; Project Start 28-SEP-1999; Project End 31-MAR-2008 Summary: (provided by applicant): The overall goals of this ACE renewal application will be to further develop our interdisciplinary basic and clinical research program at Columbia primarily focused on the evaluation of novel therapeutic approaches to human autoimmune diseases including systemic lupus erythematosus (SLE), rheumatoid and psoriatic arthritis (RA), multiple sclerosis (MS), type I diabetes mellitus (TIDM), biliary cirrhosis and scleroderma. In each of these diseases, there are ongoing basic and clinical research programs involving pathophysiologic and/or clinical immunotherapeutic studies. We hypothesize that there are four principal events involved in the immunopathogenesis of these diseases: (1) predisposing genes establish a T-cell repertoire capable of recognizing self peptides intrinsic to the autoimmune process; (2) previously tolerant autoreactive T-cell clones are activated, expand to change the T cell repertoire to reflect autoreactive effector T cells and migrate to sites of inflammation; (3) regulatory mechanisms, including cytokines and CD4+ and CD8+ regulatory T cells fail and (4) pathogenic autoantibodies and T cells effect tissue injury. We predict that reducing the clonal expansion and migration of relevant autoreactive T cells by blockade of TCR signaling with agents like anti-CD3 or interruption of the signaling and migration of autoreactive memory T cells with agents like anti-VLA-1 could down-modulate disease activity. We propose to test these hypotheses during the natural history of disease and during specific immune intervention. In this ACE renewal, we plan to continue ongoing studies of anti-CD3 therapy of TIDM, initiate trials of biliary cirrhosis employing Mycophenolate Mofetil and continue pre-clinical assessment of the VLA-1 pathway as a prelude to clinical trials with anti-VLA-1 moAbs anticipated to begin in 2004. During these studies, we will: (1) identify by PCR based CDR3 length techniques and TCR sequencing, autoantigen-driven expansions in the CD4 and CD8 cz_ TCR repertoire; (2) Identify changes in the T cell functional response to autoantigens and (3) directly study the regulatory interactions of TH1, TH2 as well as CD4+ and CD8+ T cells in controlling the TCR repertoire. In select patients, we will directly study cells at the site of inflammation (CNS, skin, kidney, joints) using HVS immortalization techniques as well as by laser capture technology for repertoire and microarray analysis of activated genes. In addition, we plan new basic studies of the

Project Title: BACULOVIRUS MEDIATED GENE DELIVERY OF HEPATITIS C VIRUS Principal Investigator & Institution: Isom, Harriet C.; Distinguished Professor; Microbiology and Immunology; Pennsylvania State Univ Hershey Med Ctr 500 University Dr Hershey, Pa 17033 Timing: Fiscal Year 2001; Project Start 01-SEP-2000; Project End 31-AUG-2003 Summary: (Applicant abstract): Chronic hepatitis C virus (HCV) infection is associated with the development of cirrhosis, an elevated risk of hepatocellular carcinoma and is currently responsible for almost 30 percent of end-stage liver disease in need of transplantation in the United States. At present, no means of prevention of HCV infection exists and treatments are unsatisfactory. HCV is highly species-specific. Only humans and a few high primates are susceptible. The only animal model for HCV vaccine or antiviral research is the endangered chimpanzee. One of the major reasons that vaccine development and antiviral therapy are lacking for HCV stems from the fact that there are no satisfactory small animal or in vitro model systems for studying HCV replication. The applicant has recently reported a novel in vitro system for delivering a replication competent HBV to cells of hepatic origin by using an HBV recombinant baculovirus. In HBV baculovirus infected HepG2 cells, HBV transcripts, intracellular and secreted HBV antigens are produced and replication occurs as evidenced by the presence of high levels of intracellular replicative intermediates and protected HBV DNA in the medium. Covalently closed circular DNA is present indicating that, in this system, HBV core particles are capable of delivering newly synthesized HBV genomes back into the nucleus of infected cells. She has also demonstrated that the HBV recombinant baculovirus system can be used to monitor the effects of an antiviral on multiple aspects of the HBV life cycle include formation of newly synthesized CCC DNA as well as the effects on preexisting CCC DNA. Based on the success with generation and usage of the HBV recombinant baculovirus system, she will test in this proposal the following hypothesis: An HCV recombinant baculovirus can be generated which is replication competent in human hepatic cells in culture and can be used to study molecular aspects of HCV replication and effects of specific anitivirals on HCV replication. The Specific Aims are: 1. To generate recombinant baculoviruses that contain all or part of the HCV cDNA under the control of mammalian promoters. 2. To test the ability of HCV-recombinant baculoviruses to express HCV gene products and replicate HCV in human cells of hepatic origin. 3. To use recombinant HCV baculovirus to evaluate the direct effect of interferon treatment on evolution of quasispecies during HCV replication in cells of hepatic origin.

Project Title: BASES OF CIRRHOSIS IN ALCOHOLIC LIVER DISEASE Principal Investigator & Institution: Zern, Mark A.; Director, Div.

Hepatic fibrogenes caused by
26
Cirrhosis
alcohol abuse or other etiologies is a complex process that involves a balance between liver cell proliferation and cell death, as well as the increased deposition and modeling of extracellular matrix (ECM) proteins. Our recent studies provide evidence for the significance of one factor, tissue transglutaminase (tTG), in many of these interactions. This ubiquitous enzyme has characteristics that may induce either apoptosis or cell proliferation, and it appears to contribute to the fibrotic process in a number of ways. This proposal is an attempt to elucidate the mechanisms by which tTG affects the process of hepatic mitogenesis or apoptosis, especially as it pertains to ethanol administration. Specific Aims: 1) To determine the pathways and functional significance of alpha-1 adrenergic signaling in hepatocytes; 2) To investigate the downstream effects of alpha-1 adrenergic signaling on hepatocyte mitogenesis; and 3) To delineate the mechanisms by which tTGase cross-linking activity inhibits proliferation and enhances apoptosis in hepatocytes. These studies will entail determining whether phenylephrineinduced hepatocyte mitogenesis acts through alpha-1B adrenergic receptor binding coupled to the tTGase G-protein subunit, Galphah, whether this activates the MAPK pathway, and by what mechanism this activation may be occurring. In addition, the mechanism by which tTGase cross-linking activity may affect upstream events in the apoptosis cascade will also be explored. Health Relatedness: It is hoped that by better understanding the molecular mechanisms by which ethanol affects fibrogenesis, hepatic mitogenesis, and apoptosis, more effective and rational therapeutic intervention may be developed.

Project Title: BILIARY SECRETORY PATHWAYS IN CYSTIC FIBROSIS Principal Investigator & Institution: Cho, Won K.; Medicine; Indiana Univ-Purdue Univ at Indianapolis 620 Union Drive, Room 618 Indianapolis, in 462025167 Timing: Fiscal Year 2001; Project Start 01-MAY-1999; Project End 31-DEC-2003 Summary: Cystic fibrosis (CF) is the most common lethal inherited diseases in white population. As CF patients live longer, liver disease has become the second leading cause of death. The development of CF disease is believed to result from the secretory defects in the bile ducts leading to the obstructions of bile ductules by tenacious bile secretions, thereby secreting in focal periportal biliary fibrosis/cirrhosis. This explanation in addition to the recent finding that CFTR is only expressed on bile duct cells, but not on hepatocytes, suggest that studying biliary secretion is crucial to understanding the pathophysiology and developing therapeutic strategies for CF liver. A novel polarized isolated bile duct unit (IBDU) prepared from rat liver has demonstrated to be an ideal tool to study bile ductular secretion but the lack of CF rat model limited its use in CF studies. By applying these isolation methods, recently, IBDUs have been isolated from normal and CF mice. Therefore, the aims of this research are to further characterize bile duct cells (BDC) and IBDU from normal and CF knockout mice, to characterize ion transporters in BDC, and to study the actions and mechanisms of various secretagogues including neuroendocrine peptides in biliary secretion in order to find ways to activate alternative, cAMP-independent biliary secretory pathways in CF mice. Preliminary experiments to isolate IBDU from normal mouse yielded intact polarized functional IBDU that responds to secretin, vasoactive intestinal peptide, and DBcAMP-IBMX. Similar IBDUs were also isolated from CF mice but need further characterization. Quantitative videomicroscopy will be used to screen potential secretagogues to stimulate biliary secretion in normal and CF mice and to characterize their underlying ion transporters by using ion substitutions and inhibitor studies. These ion transporters will be further studied by BCECF dual ratio methods for measuring pH,

micropuncture, and patch clamping techniques. Signal transduction systems involved in their action will be studied by monitoring changes in the concentrations of secondary messengers. Understanding transport systems and their underlying mechanisms of biliary secretion in normal and CF mice will help to formulate therapeutic approaches to overcome the CFTR defect. This project, in turn, will provide the candidate with an excellent opportunity to broaden and develop research and cognitive skills to become independent researcher, as well as help to successfully compete for future research grants.

Principal Investigator & Institution: Bornstein, Paul; Professor; Biochemistry; University of Washington Seattle, Wa 98195 Timing: Fiscal Year 2001; Project Start 01-FEB-1975; Project End 31-JAN-2005 Summary: The transcriptional regulation of the genes encoding the two type I collagen chains, alpha1(I) and alpha2(I), is one of special interest because these genes are expressed at widely different levels that correlate with the tissue specificity of collagen synthesis, and with development and maturation of the organism. Furthermore, the genes for alpha1(I) and alpha2(I) are responsive to cues generated by injury and repair, and by a variety of cytokines, hormones, and pharmacological agents. Finally, the expression of type I collagen genes is disturbed in orders such as pulmonary fibrosis and cirrhosis, and in diseases such as scleroderma. Although post-transcriptional mechanisms undoubtedly play an important role in regulating collagen synthesis, there is good evidence that transcriptional control represents the major means by which this regulation is achieved. A major goal of this grant is to determine how this astonishingly intricate pattern of expression is established and maintained, and how it is altered during development, in response to injury, and in disease. Current studies of gene regulation generally involve the evaluation of mutations in chimeric regulatory/reporter genes in transfection and transgenic experiments. While these approaches represent necessary preliminary steps, it is our contention that definitive results can best be achieved by testing such mutations in the context of the endogenous gene. Gene targeting techniques will therefore be used to create mutations in putative regulatory regions of the Collal gene in mice, and mutant mice will be evaluated for expression of the altered allele and for phenotypic changes. In particular, the proposed experiments will test the hypothesis that modular elements in the Collal gene direct the synthesis of type I collagen selectively to tissues such as skin and bone. It is anticipated that some of the mutations created in mice will generate useful models for human disorders of these tissues, specifically some of the Ehlers-Danlos syndromes and osteoporosis.

failure to develop an animal model simulating transfusional siderosis. Consequently, we have developed a system of cultured rat cardiomyocytes in which iron-loading with non-transferrin iron results in structural and functional abnormalities analogous with hemosiderotic myocardiopathy. In the present proposal we wish to test the hypothesis that (a) depletion of the chelatable cellular labile iron pool may permit recovery of heart cell function, documented by reversal of the iron-induced abnormalities in contractility and rhythmicity, increased lipid peroxidation, loss of sarcolemmal thiolic proteins, increased lysosomal fragility and abnormal mitochondrial respiratory function (b) that hexadentate chelators offer a predictable protective effect whereas tridentate and bidentate chelators (such as L1) may cause internal iron redistribution and a paradoxical enhancement of the harmful Fenton reaction and; (c) that lipophilic chelators are more efficient in penetrating heart cells allowing reversal of existing damage whereas hydrophilic chelators may have superior ability to prevent iron-induced damage. Hypertransfused rats with selective radioiron probes of hepatocellular and reticuloendothelial iron stores will be used to define the pools of iron available for in vivo mobilization. The ability of ascorbate to enhance chelating efficiency and of alphatocopherol to prevent peroxidative damage will be explored in both experimental systems. The proposed studies represent an essential link between the pharmacologic chemistry and potential clinical application of new iron chelators by allowing insight into their mechanism of action and cardioprotective effect, providing vital informal for the development of new strategies for the management of iron overload in thalassemic patients.

Project Title: CD36 AND HEPATIC STELLATE CELL ACTIVATION Principal Investigator & Institution: Devilliers, Willem Js.; Medicine; University of Kentucky 109 Kinkead Hall Lexington, Ky 40506 Timing: Fiscal Year 2001; Project Start 01-AUG-2000; Project End 31-JUL-2003 Summary: The central hypothesis to be examined in this R21 proposal is that the class B scavenger receptor, CD36, plays an important role in hepatic stellate cell activation and hepatic fibrogenesis through the alcohol-induced generation of lipid peroxidation products and activation of the nuclear transcription factor, peroxisome proliferatoractivated receptor gamma (PPAR-G). The major difficulty in devising specific therapies for alcoholic liver disease has been our limited understanding concerning the mechanisms underlying the progressive nature of the liver injury and fibrosis in this disease process. The class B scavenger receptor CD36 binds oxidized LDL (OxLDL) and is critical in macrophage foam cell formation and lipid flux. Oxidized cholesterol esters and lipid peroxidation products have been shown to act as ligands for PPAR-G in cells. The expression of CD36, which takes up oxidized cholesterol esters from OxLDL, is positively regulated by PPAR-G, thereby establishing a positive feedback control loop through which oxidized LDL induces greater CD36 expression which in turn leads to increased OxLDL accumulation in cells. The CD36-thrombospondin complex is required on the cell surface for the formation of activated transforming growth factor-beta (TGFb). We present preliminary data that PPAR-G agonists similarly increases CD36 expression and function in hepatic stellate cells, linking alcohol-induced generation of lipid peroxidation products and hepatic fibrosis. It is well documented in experimental models of alcoholic liver disease that addition of polyunsaturated fatty acids to the diet enhances liver injury and fibrosis. It is our working hypothesis that the CD36 scavenger receptor is upregulated in alcoholic liver disease and is critical for stellate cell activation and fibrogenesis. We therefore propose basic studies in vitro and in animal models of

liver fibrosis that address the specific role of CD36 class B scavenger receptors in hepatic stellate cell activation. We believe the proposed research is likely to generate data that will lead to a regular research project grant. The specific aims of this R21 Experimental/Developmental Proposal are: Aim 1: To determine the extent to which PPARG activation and CD36 expression regulate stellate cell activation. Stellate cell activation will be measured by Collagen expression and secretion of activated TGF-B. Aim 2: To document that stellate cells from spontaneously hypertensive rats deficient in CD36 are resistant to activation and fibrogenesis. Moreover, we will determine whether the over expression of CD36 in these CD36-deficient stellate using an adenoviral vector will reconstitute their ability to become activated in response to lipid peroxidation products. Aim 3: To determine the influence of hepatic stellate cell CD36 expression on the development of hepatic fibrosis in rodent models. We will determine whether spontaneously hypertensive rats and CD36-deficient mice are resistant to the development of hepatic fibrosis.

Project Title: CHRONIC HEPATITIS C: MOLECULAR & CELLULAR MARKERS Principal Investigator & Institution: Farrell, Geoffrey C.; University of Sydney Main Quadrangle, Bld A14 Sydney, 2006 Timing: Fiscal Year 2001; Project Start 30-SEP-1999; Project End 31-AUG-2004 Summary: Only a minority of HCV-infected individuals have progressive forms of chronic hepatitis that will result in cirrhosis in 20 to 30 years. This project is concerned with the biological basis of disease progression in chronic hepatitis C. We have noted that, to date, viral factors and the systemic immune response to HCV are poorly correlated with disease progression. The key pathobiological process that determines progression of liver disease in chronic hepatitis C is fibrogenesis, with hepatocyte cell death and proliferation playing lesser roles. In the present proposal, these processes are conceptualized as responses to hepatic inflammation and oxidative stress causing activation of hepatic stellate cells and liver cell injury. Thus our overall objective is to characterize how interactions between HCV, the hepatic inflammatory response and liver cells promote fibrogenesis and disease progression in chronic hepatitis C. In particular, we will test the hypothesis that, in the early stages of chronic HCV infection, an intrahepatic "molecular map" can be created to identify subsets of individuals who will develop progression of liver disease. We will then seek to identify patterns of hepatic gene expression that correlate with the pathogenesis of fibrosis, hepatocyte death and proliferation. A particular focus will be on the identification of genes not previously known to be associated with individual susceptibility to HCV. A unique feature of these studies is that they will be performed on serial liver biopsy samples obtained at 3 to 5 year intervals from 200 patients with mild to moderate chronic hepatitis C who will be followed prospectively and monitored by quantitative liver functional assessments. The Specific Aims are: 1) To establish the relationship between cytokine mediators of the hepatic inflammatory response, macrophage activation and the presence of oxidative stress in the liver, and to compare these with characteristics of the HCV infection in hepatocytes and other cell types; 2) To determine whether expression of these cytokines and/or oxidative stress correlate with the activity of hepatic fibrogenesis, using both cross-sectional and prospective longitudinal approaches. 3) To identify hepatic genes previously not known to be associated with a progressive course for hepatitis C. The findings may allow those individuals most at risk of progressive liver disease from HCV to be identified at a time when they are most likely to respond to antiviral therapy. It will also allow the design of adjunctive

Project Title: CIRRHOSIS AND ITS COMPLICATIONS Principal Investigator & Institution: Garcia-Tsao, Guadalupe; Professor; Internal Medicine; Yale University 47 College Street, Suite 203 New Haven, Ct 065208047 Timing: Fiscal Year 2001; Project Start 01-SEP-1999; Project End 31-AUG-2004 Summary: The candidate, Dr. Guadalupe Garcia-Tsao, is Associate Professor in the Department of Internal Medicine at the Yale University School of Medicine. She has devoted her career to patient-oriented research (POR) in the area of cirrhosis and in complications. She has been involved in a wide range of POR, from descriptive studies to multicenter randomized clinical trials. Her studies in the area of varices, variceal hemorrhage, ascites and spontaneous bacterial peritonitis have made significant contributions to the management of patients with cirrhosis, the sixth leading cause of death in the United States in individuals between the ages of 25 and 65, the productive years of life. She is recognized as a clinical research in the area of portal hypertension as attested by invitations to chair abstract selection committees and to serve as session moderator at important scientific meetings, as well as invitations to write editorials, review articles and to become panel member at international consensus panels. Ascites is one of the main complications of cirrhosis and portal hypertension and Dr. GarciaTsao's short tem goals are to focus on this complication. One of these goals is to implement a randomized trial comparing the transjugular intrahepatic porto-systemic shunt with serial large-volume paracenteses in the treatment of patients with refractory ascites. This multicenter trial, partially funded by a VA Merit Review, will analyze not only differences in efficacy but also differences in quality of life and cost, and the results can potentially change current standards of care for patients with cirrhosis. R. GarciaTsao's long-term career goals are to continue to perform POR focused on prophylactic therapy and identification of prognostic factors in chronic liver disease as well as furthering her training in health services research. Dr. Garcia-Tsao has devoted a great deal of effort toward mentoring beginning clinical investigators in POR, especially in her capacity as co-Director of the Liver Center's Clinical Core. Yale University is one of the major teaching and research institutions of the United States and as such has wellestablished research and educational resources that will continue to be utilized by the candidate. The proposed award will allow her to carry out her research and mentoring objectives successful so that she can continue to make significant contributions in the field of cirrhosis and its complications.

Project Title: COGNITIVE MECHANISMS OF ALCOHOL ABUSE Principal Investigator & Institution: Fillmore, Mark T.; Assistant Professor; Psychology; University of Kentucky 109 Kinkead Hall Lexington, Ky 40506 Timing: Fiscal Year 2001; Project Start 01-SEP-2001; Project End 31-MAY-2004 Summary: (provided by applicant): Excessive alcohol use during a drinking episode (i.e., a binge) contributes to many adverse health and social consequences. Binge drinkers are more likely to drive while intoxicated and to suffer blackouts and hangover. A continued pattern of binge drinking poses immediate health risks (e.g., alcohol poisoning, acute alcoholic hepatitis), and long-term consequences, such as alcohol dependence and liver cirrhosis. Given that even mild doses of alcohol impair

cognitive processes that control behavior, it is important to understand how such disturbances also can reduce control over alcohol intake once a drinking episode has begun. The proposed project aims to determine how the inability to curtail alcohol consumption during a drinking episode is linked to alcohol-induced impairment of cognitive processes involved in the self-control and regulation of behavior. The research will examine acute alcohol impairment of cognitive functions in young non-dependent drinkers. The project combines measures of alcohol effects on cognitive inhibitory processes with traditional abuse liability indices based on subjective rewarding effects of the drug and its ability to reinforce self-administration. Studies will determine the degree to which alcohol abuse potential is influenced by two mechanisms of drug action: 1) reward-enhancing effects (i.e., elevation of an approach "go" mechanism); and 2) impairment of cognitive inhibitory processes (i.e., suppression of an avoidance "stop" mechanism). Multiple strategies will test the role of acute cognitive impairment in the abuse liability of alcohol. A drug-reinforcement model will test the degree to which preload alcohol doses "prime" subsequent drug self-administration by impairing inhibitory control processes that regulate behavior. The research also will test an indirect alcohol antagonist drug. caffeine, and an approved medication for alcohol abuse, naltrexone, for their ability to reduce alcohol self-administration by blocking its impairing effects on inhibitory control. The research has several long-term objectives. The findings will provide an understanding of how drinkers' susceptibility to alcohol's acute cognitive-impairing effects can pose an early-onset risk factor for later alcohol dependence by promoting a continued pattern of abusive binge drinking. The research strategies also will provide methods for testing the role of cognitive mechanisms in the treatment efficacy of existing pharmacotherapies. such as naltrexone, as well as some investigational medications that might operate via cognitive mechanisms (e.g., acamprosate). Finally, the proposed experiments will provide initial methods and protocols for studying alcohol use in combination with other drugs of abuse that also disrupt cognitive functions, such as cocaine, for which binge use is also a common pattern of drug-taking.

Project Title: CONNECTIVE TISSUE GROWTH FACTOR IN HEPATIC FIBROSIS Principal Investigator & Institution: Brigstock, David R.; Children's Research Institute 700 Children's Dr Columbus, Oh 43205 Timing: Fiscal Year 2001; Project Start 01-SEP-2001; Project End 31-MAY-2006 Summary: The broad long-term objectives are to establish the role of connective tissue growth factor (CTGF) in causing fibrotic disease. CTGF is a highly pro-fibrogenic molecule which is over- expressed in all fibrotic lesions examined to date. It is transcriptionally activated by transforming growth factor-beta (TGF-beta) and mediates many of the matrix-inducing properties that have previously been attributed to TGFbeta. The studies described in this proposal focus on the role of CTGF in liver fibrosis, including that related to alcohol abuse. Preliminary data show that CTGF is overexpressed in fibrotic livers and is produced by hepatic stellate cells (HSCs), the principal fibrogenic cell type, both in response to TGF-beta and as a function of activation. HSCs show enhanced adhesion and levels of alpha smooth muscle actin in response to CTGF. In addition, ethanol and its fibrogenic metabolite, acetaldehyde, stimulate CTGF transcription in fibroblasts. Our hypothesis is that local up-regulation of CTGF in the liver drives the fibrogenic response, including that initiated by alcohol. Our Specific Aims are (1) To determine mechanisms of CTGF regulation in HSCs, including the role played by TGF-beta and acetaldehyde (which stimulate HSCs and CTGF production) as

well as retinoic acid and TNF-alpha (which inhibit HSC function and CTGF production); (2) To determine the effects of CTGF on HSC function by examining HSC DNA synthesis, division, matrix metabolism, vitamin A content, and adhesion in HSCs treated with or over-expressing various mass forms (1OkDa, 16-20kDa, 38kDa) of CTGF which occur naturally in vivo and which are a product of HSCs maintained in vitro, and to determine the role of CTGF-stimulated kinases in these processes; and (3) To produce recombinant adeno-associated viruses for the delivery of the CTGF gene into the liver in vivo to directly establish the ability of 10 kDa and 38kDa CTGF to stimulate liver fibrosis. These studies will define the fibrogenic properties of CTGF in terms of its regulation, biological properties, signaling mechanisms and protein structure. In addition, these studies will help establish whether CTGF is a therapeutic target for treating fibrosis, which is a contributing factor in 45 percent of deaths in the USA.

Project Title: CONTROL OF CAMP-MEDIATED GLUCAGON RESPONSE BY BILE ACIDS Principal Investigator & Institution: Bouscarel, Bernard E.; Associate Research Professor; Medicine; George Washington University 2121 I St Nw Washington, Dc 20052 Timing: Fiscal Year 2001; Project Start 01-SEP-2001; Project End 31-JUL-2006 Summary: Cholestatic liver disease with cirrhosis in particular, is the 9th leading cause of death in the USA. Prognosis is poor, with a generally irreversible condition marked by progressive destruction of liver cells. Around 50 percent of patients with liver disease and 80 percent of cirrhotic patients display glucose intolerance associated with decreased gluconeogenic response to glucagon. Regulation of helpatocellular metabolism by glucagon is in part through increased cAMP synthesis. The central hypothesis is that certain bile acids alter the glucagon receptor-stimulatory G protein (Gs) coupling through a phosphorylation/dephosphorylation mechanism and that these alterations are responsible for attenuation and delayed recovery of glucagon responsiveness in cholestasis. We have shown that bile acids inhibit hepatic glucagoninduced cAMP synthesis at physiologic concentrations. The effect was at the level of receptor-Gs coupling, most likely through phosphorylation, and was mediated by a calcium-dependent PKC. We have reported that hepatic glucagon-mediated cAMP production was attenuated in cholestasis in hamster induced by ligation of the common bile duct (BDL). Bile acids were either without or with reduced effects after BDL suggesting that the site of cAMP synthesis cascade altered in cholestasis is the same as that altered by bile acids. Specific aims will test the hypotheses: 1)that short-term incubation of hepatocytes with bile acids leads to decreased glucagon receptor-Gs coupling through a phosphorylation/dephosphorylation mechanism involving PKC; 2)that alteration of both glucagon receptor-Gs coupling and receptor dephosphorylation are responsible for the respective attenuation and delayed recovery of glucagon responsiveness in cholestasis. In HEK293 clones expressing glucagon receptor, and in hepatocytes from BDL hamsters we will study the respective effect of physiologic/pathophysiologic bile acid concentrations and cholestasis on receptor/Gs coupling and phosphorylation using a multifaceted approach designed to determine the protein phosphorylation target. We will study the role of protein phosphatases on the time course of glucagon response recovery in cholestasis. Knowledge gained from these studies will have bearing on both diagnosis and treatment of cholestatic hepatobiliary disorders. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen

Project Title: DETERMINANTS OF HEPATITIS C & E MORBIDITY IN EGYPT Principal Investigator & Institution: Strickland, George T.; Epidemiology and Prev Medicine; University of Maryland Balt Prof School Baltimore, Md 21201 Timing: Fiscal Year 2003; Project Start 15-SEP-2000; Project End 31-AUG-2005 Summary: By using new molecular virological techniques, Non-A Non-B hepatitis patients have now been categorized into those infected with hepatitis C virus (HCV), a parenterally transmitted flavivirus, and hepatitis E virus (HEV), a fecal-oral transmitted "hepatitis E-like virus." WHO estimates that 170 million are infected with HCV, the most common cause of chronic viral hepatitis (CVH), post-necrotic cirrhosis of the liver and hepatocellular carcinoma (HCC). HEV is primarily transmitted in developing countries where it is the most common cause of acute viral hepatitis (AVH) and fulminating hepatitis, particularly in pregnant women. We and others have documented that the highest prevalence of HCV, and also possibly HEV, in the world occurs in Egypt. We have established a Network of Egyptians and Americans who are studying viral hepatitis and its cost to the country. In this ICIDR proposal, we will extend the work of this Network to include investigations of: (1) the effect that the host genome has on chronicity and cirrhosis following HCV infection (Project 1); (2) the host, viral, and environmental determinants of HCC and (because HCV is lymphotrophic as well as hepatotrophic) non-Hodgkins lymphoma (NHL, Project 2); and the epidemiology and complications of HEV (Project 3). Projects 1 & 2 will have case-control studies. The former will compare: (a) chronic carriers of HCV RNA vs. subjects who clear infection and (b) those with HCV who develop cirrhosis vs. those that show no signs of disease; while the latter compares HCC or NHL cases vs. age- and gender-matched controls. Projects 1-3 will have prospective cohort studies of 10,000 inhabitants of two villages with prevalence of anti-HCV of 9% and 24% and anti-HCV of 51 and 70%, respectively. Their goals will be to determine incidence of, and risk determinants for cirrhosis (Project 1), HCC and NHL (Project 2), and HEV infection and disease (Project 3). A cohort of pregnant women and children will be studied to assess HEV morbidity in pregnancy and exposures and disease in infancy. Domestic animals and peri-domestic rodents will be studied to determine whether HEV has a zoonotic component in Egypt. Viral genotypes, host class I and II alleles and candidate genes, e.g., chemokine receptors and HDL, a possible HCV receptor, and environmental exposures and their impact on host genes (p53 genetic fingerprinting) will be assayed. Because the scientific, administrative, logistic and laboratory network is in place and both HCV and HEV have such a high prevalence in Egypt, these investigations have a high probability of early success. Explanations for these very important questions can be obtained at a fraction of the cost and time as they could be found elsewhere, and the results should lead to the development of better interventions to prevent the two most important causes of liver disease in the world.

We hypothesize nondiabetic homozygotes for mutations in HFE will exhibit a defect in insulin secretion

as iron overload develops. This notion is supported by preliminary data obtained in HFE mutant mice. The insulin deficiency will progress to type 2 diabetes only if insulin resistance also occurs, either from cirrhosis or inheritance of type 2 diabetes genes. Insulin resistance from cirrhosis is hypothesized to result from excess carbohydrate delivery to peripheral tissues, resulting in excess hexosamine generation, an established cause of insulin resistance. Our specific aims are to: 1. Determine the prevalence of impaired glucose intolerance (IGT) and diabetes in clinically unselected individuals with hemochromatosis by oral glucose tolerance criteria. 2. Determine if a defect in insulin secretion exists in nondiabetic homozygotes with or without iron overload. This will be accomplished using the frequently sampled intravenous glucose tolerance test (FSIVGTT) with insulin levels. Reversibility of the defect will be examined after subjects have undergone phlebotomy. The hypothesis will be verified in studies of isolated islets from mice carrying disrupted or mutant HFE genes. 3. Using animal models, determine if diabetes in hemochromatosis results only when insulin resistance is superimposed on an iron- mediated defect in insulin secretion. 4. Determine the sequence and relative contributions of insulin resistance and hepatic glucose production (HGP) in the evolution of diabetes in human hemochromatosis. Insulin resistance and HGP will be quantified by the hyperinsulinemic euglycemic clamp and stable isotope techniques in subjects with hemochromatosis who have normal or IGT, with or without hepatic involvement.

Project Title: EFFECT OF CIRRHOSIS AND SHUNTS ON DRUG DISPOSITION Principal Investigator & Institution: Gorski, J. Christopher.; Associate Professor of Medicine; Medicine; Indiana Univ-Purdue Univ at Indianapolis 620 Union Drive, Room 618 Indianapolis, in 462025167 Timing: Fiscal Year 2002; Project Start 15-AUG-2002; Project End 31-JUL-2007 Summary: (provided by applicant): It is well established that hepatic cirrhosis results in reduced clearance of drugs that are highly metabolized and an enhanced sensitivity to the pharmacological and adverse actions of drugs. Chronic alcohol consumption and hepatitis C are the two most common causes of cirrhosis in the United States with an incidence of 3.1 per 1000 people. The development of portal hypertension is the primary mechanism behind several major complications of cirrhosis such as bleeding from gastroesophageal varices, hepatic encephalopathy, and ascites. Transjugular intrahepatic portosystemic shunts (TIPS) and other surgical shunts are performed to manage these complications of portal hypertension. We have demonstrated that in addition to a reduction in hepatic clearance, cirrhotic patients with TIPS experience an increase in intestinal availability of midazolam, a selective cytochrome P450 3A (CYP3A) substrate. This increased bioavailability primarily reflects a functional lack of intestinal wall firstpass metabolism relative to cirrhotics without TIPS and healthy volunteers. The mechanism for this lack of intestinal wall metabolism is unknown. We propose to characterize the mechanism and consequences of this loss of intestinal wall CYP3A activity in cirrhotics with TIPS by directly examining the CYP3A protein and mRNA levels, intestinal permeability, and in vivo hepatic and intestinal CYP3A activity before, immediately after, and I month after TIPS placement. Cirrhotic patients with TIPS, and potentially other types of portosystemic shunts, are expected to be at risk for excessive pharmacological effects or suffer from an increased incidence of adverse reactions following CYP3A substrate administration. We will examine the susceptibility of these individuals to adverse drug reactions and drug-drug interaction by examining the ability of erythromycin to prolong the QT interval and clarithromycin to inhibit

metabolism of buspirone, a CYP3A substrate. Finally, the expression of other enzymes such as UDP-glucuronosyltransferases (UGTs), sulfotransferases (SULTs) and pglycoprotein may also be altered in cirrhosis. We will characterize the changes in these enzymes using the partial clearance of acetaminophen to glucuronide (UGT) and sulfate (SULT) conjugates and the disposition of fexofenadine in cirrhotics with and without TIPS and healthy volunteers.

Project Title: EFFECT OF HEPATOTOXINS & ADOMET ON LIVER GENE EXPRESSION Principal Investigator & Institution: Kruger, Warren D.; Member; Fox Chase Cancer Center Philadelphia, Pa 19111 Timing: Fiscal Year 2002; Project Start 30-SEP-2002; Project End 31-AUG-2004 Summary: (provided by applicant): Chronic liver disease such as cirrhosis, hepatitis, fibrosis, and fatty liver, is associated with reduced levels of S-Adenosylmethionine (AdoMet) in the liver. AdoMct affects a variety of metabolic pathways including methylation, anti-oxidant defense and polyamine production. Evidence from a variety of model systems suggest that dietary supplementation with AdoMet can attenuate liver damage and improve liver function. Despite these intriguing observations, little is known about the effect of AdoMet supplementation at the molecular level. In this R21 exploratory proposal we will examine the effects of AdoMet supplementation at the level of gene expression on a global scale using a rodent model. We will test the hypothesis that hepatotoxins, such as alcohol, have discreet effects on gene expression and that AdoMet supplementation can reverse at least some of these effects. Our experimental approach will use Wistar rats that are assigned to one of six groups: untreated AdoMet treated, alcohol treated, alcohol+AdoMet treated, CCI_ treated, and CC14+AdoMet treated. Using DNA microarrays we will compare global gene expression patterns in each of these groups and determine what! genes and biological pathways are affected by various hepatotoxins and AdoMet supplementation. In addition, we will measure various AdoMet metabolites in the liver to determine the effect of these treatments on AdoMet metabolism. From these studies we will determine how liver hepatotoxins and AdoMet affect gene expression profiles. This information should be informative as to what types of biological pathways are perturbed by these treatments. This knowledge will be useful in understanding the molecular changes that characterized liver disease and the molecular basis for clinical improvement with AdoMet in liver disease. This work may also be useful in the identification of biological pathways affected in chronic liver disease that are not affected by AdoMet supplementation, which may represent other correctable targets in chronic liver disease.

However, little is known about the mechanism of the AC effects. One feature of the activated Collagen producing HSC is the loss of

retinoid storage. Our study, based on the hypothesis that the loss of retinoic acid (RA) plays a role in alcoholic cirrhosis, has indicated that a) RA inhibits the basal activity of a2(I) Collagen promoter and represses the AC induced activation of the promoter in transdifferentiated HSC; b) RA induces the expression of RA receptor b (RARb) while AC decreases RARb land retinoid X receptor alpa (RXR a) in HSC; c) the RA effect on a2(I) Collagen promoter does not occurs at the RA response element (RARE) site we studied. RAR and RXR are known to function as heterodimers. RXR can also act independently of RAR. We hypothesize that RXR a is an equally essential part of the regulation of a 2(I) collagen promoter by RA, and that the cis-acting element(s) in the promoter may preferentially interact with RXR in the RA-RAR/RXR regulatory mechanism. Our Specific Aims are to: 1) examine the regulatory role of RXR in CC2(l) Collagen expression in HSC and the influence of RA and AC on RXR expression in HSC; 2) determine whether RAR and/or RXR bind to the rat a2(I) Collagen promoter and characterize the nature of the binding; and 3) identify other possible trans-acting factor(s), such as the cofactors of nuclear retinoid receptors), SP-1 and AP-2, in the R-A regulatory pathway on a2(I) Collagen expression specifically in HSC. We hope that this project will extend our understanding of the mechanism(s) for the activation of type I Collagen expression in liver fibrogenesis and ultimately lead to potential treatment and prevention of cirrhosis. This project is the continuation of ongoing studies the candidate has performed under the mentorship of Dr. Esteban Mezey who has made ma or contributions in the field of alcoholic liver pathogenesis. It is an essential part of the structured career development plan, to extend Dr. Wang's knowledge and to further develop her skills, leading to an independent academic career.

Project Title: ENDOTHELIN AND LIVER CIRRHOSIS Principal Investigator & Institution: Gandhi, Chandrashekhar R.; Research Assistant Professor of Surgery; Surgery; University of Pittsburgh at Pittsburgh 350 Thackeray Hall Pittsburgh, Pa 15260 Timing: Fiscal Year 2001; Project Start 25-SEP-1998; Project End 31-AUG-2003 Summary: The current pharmacologic and surgical therapies for portal hypertension a notoriously frustrating, often fatal, clinical complication of liver cirrhosis, have limited success due to the lack of clear understanding of its pathophysiology. Our work strongly indicates a major role of endothelin-1 (ET-1), a powerful vasoconstrictor, mitogen and fibrogen, in these pathologies. We observed progressive increases in hepatic ET-1 and its receptors during carbon tetrachloride (CC14)-induced cirrhosis in rats, and in cirrhotic humans. We demonstrated that a ET-1 receptor antagonist TAK-044 ameliorates portal hypertension and hepatic injury in CC14-treated rats. Further, we have shown that ET-1 stimulates the synthesis of a potent fibrogenic agent transforming growth factor-beta1, and exerts contractile and fibrogenic effects in perisinusoidal stellate cells. Stellate cells, the physiologic regulators of hepatic architecture and vascular tone, proliferate and transform into highly contractile and excessively fibrogenic myofibroblasts during liver cirrhosis. ET-1 also stimulates synthesis of a potent hepatic vasoconstrictor and systemic vasodilator platelet-activating factor (PAF) in Kupffer cells. PAF has been suggested to play a major role in hemodynamic abnormalities associated with cirrhosis. These observations indicate that interactions between ET-1, stellate cells and Kupffer cells are the major mechanism in the pathogenesis and complications of liver cirrhosis. Therefore, we propose to distinguish precise sites of changes in ET-1 and its receptors during the development of CC14induced cirrhosis using the techniques of immunohistochemistry, in situ hybridization

37
and cell fractionation. We will also delineate the mechanisms of (1) the elevated ET-1 levels during the development of cirrhosis; (2) the actions of ET-1 in causing structural and functional changes in stellate cells; and (3) the interactions between ET-1 and Kupffer cells with specific focus on PAF synthesis. Finally, we propose to evaluate the therapeutic potential of ET-1 receptor antagonists by administering them to rats (a) during the entire period of CC14 treatment; (b) from the time of transition between fibrosis and cirrhosis; and (c) after the development of cirrhosis to ascertain amelioration or reversal of the pathologic process. Thus, in addition to the determination of the molecular mechanisms of the role of ET-1 in liver cirrhosis, this investigation will provide valuable information for the development of appropriate therapeutic strategies for liver cirrhosis and its complications.

Project Title: ENZYMATIC DIFFERENCES AMONG HEPATITIS C VIRUS GENOTYPES Principal Investigator & Institution: Frick, David N.; Biochem and Molecular Biology; New York Medical College Valhalla, Ny 10595 Timing: Fiscal Year 2003; Project Start 15-FEB-2003; Project End 31-JAN-2008 Summary: (provided by applicant): Almost one in every fifty-five Americans have been exposed to the Hepatitis C Virus (HCV), but most are unaware of their infection because the virus causes few acute symptoms. If left untreated, the majority of HCV infections lead to chronic active hepatitis that eventually progresses to cirrhosis, cancer, or liver failure. Current therapies involving the drugs interferon and ribavirin are costly and produce debilitating side effects, frequently worse than the symptoms produced by HCV itself. Newer treatments are, however, quite effective against certain viral genotypes. This proposal will examine the HCV proteins most directly involved in viral replication, the NS3 Helicase and NS5B polymerase, as putative targets for the drug ribavirin and as targets for new antiviral agents. In addition to its established role as a modulator of the immune system, ribavirin has been proposed to eliminate viruses as a mutagen or through direct effects on viral replicative proteins. One popular hypothesis states that ribavirin's enhancement of the already high HCV mutation rate leads to a catastrophe of errors and subsequent virus elimination. Here, ribavirin effects will be examined in vitro, in enzyme assays, and in vivo, using a novel HCV replicon that should allow the assessment of replication fidelity. To attempt to relate ribavirin effects to genotype-specific drug response, all experiments will be repeated with the three most common American HCV genotypes, two that normally do not respond to therapy (la and lb) and one that frequently responds to therapy (2a). The polymerase and helicase proteins from each genotype will also be characterized to define conserved and divergent properties. A rigorous biochemical approach will be used to define enzyme differences because sequence data alone does not accurately predict protein structure or function. Preliminary data show that different genotypes encode enzymes with markedly different properties, hampering current rational drug design efforts. Structure-based site-directed mutagenesis will be used to determine the genetic basis for HCV enzyme variability. The biological consequences (i.e. replication rate, fidelity, protein expression) of HCV genetic variation will then be analyzed in a replicon system. The delineation of genetic variations responsible for certain phenotypes might allow the prediction of patient response to current or future HCV therapies, and the clear identification of conserved HCV enzyme properties will aid future HCV drug development.

Project Title: EPIDEMIOLOGY OF PRIMARY BILIARY CIRRHOSIS Principal Investigator & Institution: Gershwin, M. Eric.; Professor of Medicine; Internal Medicine; University of California Davis Sponsored Programs, 118 Everson Hall Davis, Ca 95616 Timing: Fiscal Year 2001; Project Start 01-SEP-2000; Project End 31-AUG-2005 Summary: Primary biliary cirrhosis (PBC) is an enigmatic autoimmune disease characterized by female predominance, high titer anti- mitochondrial antibodies (AMA), small bile duct destruction, and liver failure. Our group was the first to clone and identify the mitochondrial antigens, a family of phylogenetically conserved 2- oxo acid dehydrogenase proteins recognized by T and B cells in PBC. In addition, recent data has provided us with the basis for the following working hypotheses. We submit that PBC is most likely the result of an inappropriate or malcontrolled response to an environmental (either chemical or biological) insult. The initiating insult in PBC could be either a urinary tract infection (UTI) or an exposure to halogen containing chemicals. In the case of UTI's, there are high degrees of homology between the mitochondrial proteins present in micro-organisms that characteristically cause UTI's and their eukaryotic (i.e. human) analogs. Alternatively, the liver-based metabolism of halogenated hydrocarbons as xenobiotics generates activated halogen containing intermediates that react to form halogen modified proteins. In both, UTIs and halogenated chemical exposures, the introduction of these foreign proteins may initiate an immunological response that results in the immune system inappropriately targeting self proteins. These insults, which appear to be necessary but are not sufficient to elicit an autoimune response, given their widespread occurrence, needs to occur in conjunction with other disease associated contributory factors (i.e. genetic background) to produce PBC. We propose to take advantage of our strengths, including a nationwide network of PBC researchers, to accomplish this goal. We will collect and analyze data on demographics (race/ethnicity, socio-economic status, place of birth), medical history, reproductive history (parity, birth outcomes/complications, fertility problems, oral contraceptive use), menstrual history (age at menarche, age at menopause, average cycle length, cycle regularity) and lifestyle factors (smoking, physical activity, occupation and occupational exposures) using a questionnaire that we have tested in a preliminary study of 201 patients and 171 unaffected siblings. The project data will be collected from a sample of 2000 cases from 17 medical centers around the country and an equal number of matched (on age, gender and residence) random-digit dialed controls. The proposed study would be the first comprehensive epidemiologic study of PBC to be conducted in the United States, and directed at testing our thesis in the hope of improving our understanding of this serious disease and potentially identifying preventive measures.

It affects men and women equally, and impacts on all races and socio- economical levels. Portal hypertension is the main complication of cirrhosis, regardless of etiology.

portal pressure and have been shown to prevent the first variceal hemorrhage in patients with cirrhosis and varices. Early portal hypotensive therapy, before the patients develop varices, would be beneficial not only because it may prevent or delay the formation of varices (and variceal hemorrhage) but because it may prevent or delay the development of other complications of portal hypertension, such a ascites. This ongoing multi-center, prospective, randomized, placebo-controlled, double-blind trial was designed with the primary aim of investigating if early therapy with timolol, a nonselective beta-adrenergic blocker, can prevent or delay the development of varices in patients with cirrhosis and portal hypertension. Secondary aims will examine whether timolol prevents or delays other complications of portal hypertension such as ascites and porto-systemic encephalopathy, as well as liver transplantation or death. Patients with cirrhosis, without varices on endoscopy and with portal hypertension (portal pressure greater than 6 mmHg) are included in the study. This grant application was funded in April of 1993 and patient randomization began in August of 1993. Patient accrual took longer than originally estimated, however it is now certain that the number of 190 patients required for the study will have been randomized by the end of the current funding period (March 1998), since at the writing of this proposal 158 patients had already been randomized. In calculating sample size, we assumed a rate of development of varices of 50 percent at 4 years in the control arm, to be reduced to 30 percent in the timolol arm. So far our observed rates for development of varices are consistent with our planned estimates. However, we have now estimated that a minimum follow-up of 4 years (after last patient is recruited) is necessary to ensure high statistical power (80 percent at the 2-sided 0.05 level). The trial is highly significant for the promise it holds for the treatment of cirrhosis of all etiologies and for an understanding of the natural history of the disease. The four centers involved are widely renown for their studies in this area and have collaborated productively in the past, including the only published double-blind trial of propranolol in the prevention of first variceal hemorrhage in patients with cirrhosis and varices.

While this principle is applicable in all organs affected by ethanol, the response in different tissues can vary widely. Thus, a study of the metabolism associated with ethanol can be focused on different responses in different organs. The studies encompassed in this application for a Senior Scientist award are directed toward the effects of ethanol on metabolic systems in liver and brain. With regard to the liver studies, the major goal is to relate alterations in metabolism to development of alcoholic liver disease. Included are studies of the effects of ethanol on 1) the integrity of the mitochondrial oxidative phosphorylation system and 2) the synthesis of ATP via the glycolytic pathway. Experiments are included to examine how ethanol-elicited alterations in the above mechanisms affect the structural and functional integrity of the hepatocyte. The interplay between oxidative stress and cellular energy state in the ethanol- related loss of hepatocyte viability will also be evaluated. The metabolic studies in the brain, which are a new area for me, are focused on establishing alterations in

glucose and neurotransmitter metabolism that accompany the behavioral changes occurring when an individual self-administers ethanol. The synthetic pathways for the amino acid and biogenic amine neurotransmitters will be investigated in a rodent selfadministration model. The purpose for the Senior Scientist application is to obtain enough research time to allow me to add the neurotransmitter metabolism study while I maintain current effort on my liver-ethanol program.

Project Title: FUNCTION AND REGULATION OF CGMP GATED RENAL K+ CHANNELS Principal Investigator & Institution: Desir, Gary V.; Professor of Medicine; Internal Medicine; Yale University 47 College Street, Suite 203 New Haven, Ct 065208047 Timing: Fiscal Year 2001; Project Start 01-APR-1994; Project End 31-MAR-2002 Summary: (Adapted from the Applicant's Abstract): The kidney is the main organ involved in the long term regulation of total body potassium. Disorders of potassium balance occur frequently in patients who have hypertension, congestive heart failure, cirrhosis of the liver and renal dysfunction. Hypokalemia causes significant cardiovascular morbidity and mortality in patients treated with diuretics. Furthermore, abnormal regulation of K channels may play a role in the pathogenesis of hypertension. This laboratory is focused on the study of renal potassium channels. This work has let to the discovery of several novel K channel genes. One of these genes encode a cGMPactivated, K-selective channel (KCNA 10a) which is expressed in kidney, heart, muscle and blood vessels. KCNA10a has kinetic properties similar to those of the nitric oxide sensitive K channels detected in pulmonary artery smooth muscle cells. The work now proposed is an extension of the original proposal. The investigative team has recently succeeded in optimizing KCNA10a current expression in Xenopus oocytes and are now able to study its kinetic properties of the single channel level in detail. They will then determine if it is a hetero-multimeric protein and if its expression levels and/or kinetic properties are modulated by any of the live previously cloned a subunits. They will investigate the regulation of KCNA10a by cGMP and ask whether cGMP activates by binding to the cGMP-binding domain and/or via protein phosphorylation. Finally, a panel of high affinity polyclonal antibodies specific for the KCNA10a protein will be developed in order to examine its tissue distribution and membrane localization. The intent is that studies already carried out and those that are proposed in the current application will provide insight into the mechanisms by which K balance is maintained and should, therefore, have direct clinical applications. It is also hoped that the discovery of new molecular structures will expand the existing physiological framework of potassium homeostasis and will lead to the development of new therapeutic agents.

that the HCV major envelope glycoprotein E2 interacts with the cell surface molecule CD81, which may serve as a virus receptor. CD81 is expressed on many different human cell types, including B lymphocytes, where it is known to associate with other molecules including CD19, MHC Class II antigen, lymphocytes, where it is known to associate with other molecules including CD19, MHC Class II antigen, and the C3 receptor. CD81 participates in several functional activities of B cells, including aggregation, adhesion, and antigen- receptor-mediated activation. B cell abnormalities have been associated with chronic HCV infection, including polyclonal activation with or without cryoglobulinemia, several other dyscrasias, and some rare lymphomas. In addition, the propensity for delayed seroconversion during acute HCV infection and the emergence of antibody-escape mutants during the chronic phase of disease raises the question of whether fundamental disturbances in normal B cell function occur as a consequence of either their infection with virus or chronic exposed to E2 glycoproteins on circulating virus. Although it has not been established that antibody responses to HCV are important correlates of protein against persistent infection, defective B cell function and impaired humoral immunity could contribute to inefficient clearance of virus in some cases, particular if other factors such as cytotoxic T cell responses are weak. We propose to investigate the hypothesis that interaction of E2 with CD81 on the plasma membrane of B lymphocytes and/or within intracellular compartments, leads to alterations in the properties of this multi-functional ell surface protein that in turn compartments, leads to alterations in the properties of this multi-functional cell surface protein that in turn affect the capacity of B ell s to respond normally to viral antigens. Such alterations could include higher thresholds for activation, reduced antigen presenting capacity and/or defective complement regulation. Using model systems, and clinical specimens of HCVinfected individuals, we specifically will: 1) Investigate whether chronic infection with HCV is associated with disturbances in B cell function, such as reduced level of CD81 expression, impaired responsiveness to antigen, and other in vitro measures of activation; 2) Determiner whether exogenous E2 interacts with CD81 on B cell lines and whether such interaction leads to alterations in CD81-associated events; 3) Determine whether E2 interacts with CD81 during intracellular synthesis and processing in B cells, and whether there are functional consequences for cell surface CD81 expression and function.

Project Title: GENE EXPRESSION IN THE HUMAN ALCOHOLIC BRAIN Principal Investigator & Institution: Harris, Robert A.; Professor of Pharmacology; Neurobiology; University of Texas Austin 101 E. 27Th/Po Box 7726 Austin, Tx 78712 Timing: Fiscal Year 2001; Project Start 01-AUG-2000; Project End 31-MAY-2005 Summary: (Adapted from the Investigator's Abstract) The overall goal of this project is to identify genes which are differentially expressed in alcoholics as compared to nonalcoholics. This will be accomplished by collecting autopsy material from individuals extensively characterized for drinking history, other pathologies, drug and tobacco use, brain histology, and genotype. In addition to the existing Australian Brain Bank, one of the most extensive for alcoholic cases available in the world, emphasis will be placed on collecting additional cases with specific attributes, such as abstinent alcoholics. Gene expression will be measured in frontal and motor cortex by microarrays that simultaneously measure levels of up 7000 expressed genes from a single sample of brain RNA. Our preliminary results demonstrate the feasibility of these approaches and suggest changes in gene expression consistent with published studies as well as changes in novel genes. About 30 genes of particular merit and interest will be selected for

detailed analysis with a particular emphasis on correlating changes in mRNA expression to protein expression. Gene expression in the alcoholic brain may be changed due to predisposing factors (susceptibility genes), as a consequence of chronic ethanol exposure (alcohol responsive genes) or as a consequence of alcoholic neuropathology, other pathology (e.g., cirrhosis) or co-morbidity (e.g., tobacco use). We propose that careful case selection for analysis of gene expression will allow us to distinguish among (at least some of) these possibilities.

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 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

Project Title: HCV & ALCOHOL-- EPIDEMIOLOGY & HOST-VIRUS CORRELATES Principal Investigator & Institution: Peters, Marion G.; Professor; Medicine; University of California San Francisco 500 Parnassus Ave San Francisco, Ca 94122 Timing: Fiscal Year 2001; Project Start 30-SEP-2000; Project End 31-JUL-2005 Summary: Alcohol and hepatitis C virus (HCV) infection are recognized as independent causes of chronic liver disease and cirrhosis. Further, significant alcohol ingestion, defined variably as >30 gnvday (women) or >50-60 grnlday (men) has been associated with more severe histological disease, including cirrhosis and hepatocellular carcinoma and an accelerated rate of disease progression in patients with chronic HCV infection. The effect of more limited alcohol intake or non-daily drinking patterns on the progression of HCV disease are not known. In this study, we will establish a prospective cohort of at least 550 HCV-infected patients who drink varying amounts of alcohol at study entry. Total lifetime alcohol intake, patterns of alcohol ingestion, and periods of abstinence will be ascertained using validated questionnaires (Skinner, 1979; Russell, 1991) at study entry and annually for four years. Additional data collected at study entry include demographic, epidemiological and dietary history (including duration of HCV infection, mode of acquisition, use of iron supplements). A comprehensive evaluation of HCV RNA including viral titer in serum, liver and peripheral blood mononuclear cells (PBMCs), and baseline quasispecies complexity, will be obtained. Subjects with an alcohol intake of >30 gm/day (females) or >60 gm/day (males) will be counseled to completely abstain. A subset of 150 subjects drinking <15 gm/day (females) or <30 gm/day (males) of alcohol will be randomized to abstinence or no change in alcohol intake (control group). Annually we will readminister an alcohol questionnaire (12-month quantity/frequency questionnaire, National Alcohol Survey) and perform tests for ferritin, transfenin saturation, and serum aminotransferase activity. HCV viral quasispecies variability (assessed by heteroduplex mobility assay) HCV RNA quantitation and cytokine profiles will be compared in different tissue sources (serum, PBMCs and liver). Liver biopsies will be obtained at baseline and at the end of 4 years follow-up to assess severity and progression of liver disease. This study will determine 1) the quantity and pattern of alcohol intake associated with progression of HCV liver disease; 2) whether abstinence from alcohol among "moderate" or "light" drinkers reduces the rate of HCV disease progression; and 3) the host (including proinflammatory or profibrotic host genes which may be activated in the presence of alcohol) and viral factors (including quasispecies heterogeneity which may be altered by alcohol ingestion) which underlie the enhanced rate of disease progression in HCVinfected patients using alcohol.

A significant proportion of patients have a rapid recurrence of hepatitis that leads to graft loss and mortality. The dynamic nature
44
Cirrhosis
of HCV populations could underlie its biology, including immune evasion and persistence. We propose to study the transmission and evolution of HCV quasispecies 65 liver transplantation recipients. Aim 1: Is there a selection of viral variants within quasispecies at the time of transmission? We hypothesize that not all viral variants present in infectious blood are able to establish infection in a susceptible host. Therefore, we will compare the composition of viral quasispecies in all 65 transplant recipients using single-strand conformation polymorphism (SSCP), cloning and sequencing to evaluate changes that correlate with the clinical course. This analysis will be conducted in the highly variable E2 and conserved 5' untranslated (5'UTR) regions. Aim 2: How does the HCV quasispecies distribution evolve over time in the natural course of infection and does it have a prognostic value with respect to outcome? We hypothesize that in OLT recipients infected with HCV, the quasispecies composition evolves in the E2 and 5'UTR regions and these changes correlate with the clinical outcome. Therefore, we will analyze quasispecies complexity, divergence and genetic drift longitudinally using SSCP and heteroduplex mobility assays in all 65 infected recipients. We will correlate quasispecies behavior with clinical outcome of the infection. Aim 3: What is the biological basis of selective transmission and evolution of quasispecies in the E2 and 5'UTR regions? We hypothesize that the selection and evolution of variants within the 5'UTR quasispecies is related to differences in viral fitness associated to its competence to direct translation. We will clone representative 5'UTR fragments into bicistronic dual luciferase reporter plasmid and we will measure and compare their translation efficiency in vitro. We hypothesize that E2 region quasispecies variants bound by antibodies are less efficient in establishing infection in the graft. Furthermore, we postulate that new viral variants appearing during the infection represent mutants which escape immune detection. We will separate viral variants bound in immunocomplexes from "free" virus and compare the variants using SSCP, cloning and sequencing.

Liver injury may be caused by an interaction of the virus with the host immune response leading to inflammation and fibrosis in the liver. We plan to examine the mechanism of HCV induced liver injury in three distinct groups of patients: 1) those with chronic HCV infection and evidence of moderate to severe necroinflammatory disease, who are at average risk of progression to cirrhosis; 2) those with persisting viremia but normal or minimally elevated transaminases and normal or mildly inflamed liver biopsies, who are at low risk of progression to cirrhosis; and 3) patients with chronic HCV liver disease and active daily alcohol use (greater than 50 gm/day), who are at the highest risk of progression of liver disease. Specifically, we propose to evaluate the role of intrahepatic viral load on immune response and liver injury by measuring liver derived CTL response and cytokine production and correlating the immune response to the degree of liver injury. The response in the liver will be compared with that seen in the periphery to determine whether there is compartmentalization of immune responses and whether peripheral immune response

can correlate with the injury and immune response seen in the liver. The role of antiviral therapy and alcohol on these responses will also be studied.

Recently an HLA Class 1 gene, HLA-H was implicated in the etiology of this disease. Over 80 percent of hemochromatosis patients are homozygous for a C282Y mutation. Compound heterozygotes for C282Y and H62D appear to have an increased incidence of the disease. Sixty-thousand adults undergoing health care screening in the KaiserPermanente system will be screened, determining serum iron, iron binding capacity, ferritin, and mutations in HLA-H. Patients classified as having hemochromatosis will be phlebotomized to remove excess iron and to measure iron stores. This will establish the relationship between genotype, age, sex and clinical state, and size of iron stores, and provide data that can be used to guide programs screening for hemochromatosis. The hypotheses that heterozygotes are more susceptible to cardiovascular disease and other disorders and that they are benefited by being less susceptible to iron deficiency anemia will be tested using the extensive Kaiser-Permanente database. Hemochromatosis mutations, other than those known, will be sought. The HLA-H gene product may function like other HLA class 1 genes, binding peptides and associating with proteins such as beta2 microglobulin, calreticulin, transporter associated with antigen processing (TAP) and tapascin. Alternatively, it may function as a signaling molecule, like the Fc receptor. Determining how the HLA-H gene product functions should provide insight into its role in maintaining iron homeostasis. This will be done by using immunoprecipitating HLA-H containing complexes, determining HLA-H Fc receptor signaling properties and measuring the binding of peptides and other small molecules by HLA-H.

These patients display a variety of neuropsychological deficits as well as clinical and serum ammonia abnormalities. Subclinical hepatic Encephalopathy (SHE) is a subtler accompaniment of cirrhosis that is associated with neuropsychological abnormalities without significant neurologic findings such as asterixis. Although neuropsychological tests are the current standard
46
Cirrhosis
for diagnosing SHE, the results are non-specific and reveal little about the underlying neurochemical processes. Cerebral Magnetic Resonance Spectroscopic (MRS) metabolic alterations and MRI signal abnormalities in the basal ganglia reveal a relationship between neuropsychological functioning and biochemical abnormalities found in patients with SHE. This study will involve collaboration among hematologists, radiologists, psychiatrists, MR physicists and neuropsychologists. We will identify a total of 60 liver failure patietns who have SHE and compare them to 60 healthy control subjects. These patients and healthy controls will undergo clinical assessment by hepatologists and neuropsychiatric evaluation by psychiatrists. Subsequently, they will undergo a comprehensive series of neuropsychological tests to characterize the nature of their neurocognitive deficits. Following these tests, all subjects will undergo MR Imaging and Spectroscopic (MRI/MRS) examinations. We aim to use 1H MRS to meare and compare absolute cerebral metabolite levels of myo-inositol, choline, and glutamine/glutamate in the frontal lobe, parietal lobe and basal ganglia of a matched group of SHE patients and healthy controls. The resulting MRS and MRI data will be quantitatively analyzed and correlated with the results of neuropsychological testing and clinical examination. Multivariate methods and correlational analysis will be used to test hypotheses regarding differences between SHE patients and controls. We hypothesize that myo-inositol will be decreased, glutamine/glutamate will be increased and choline will be decreased in patietns with SHE. We propose that these underlying biochemical abnormalities will be correlated with clinical, neuropsychiatric and neuropsychological aspects of SHE. If these relationships are found, they will provide an improved biochemical understanding of the underlined aspects of SHE as characterized y clinical and neuropsychological testing. This enhanced understanding of pathophysiology will improve our ability to diagnose and treat this condition, resulting in improved patient outcomes.

Project Title: HEPATIC STELLATE CELL ACTIVATION INDUCED BY HCV Principal Investigator & Institution: Brenner, David A.; Professor; Medicine; Columbia University Health Sciences New York, Ny 10032 Timing: Fiscal Year 2003; Project Start 30-SEP-2003; Project End 31-AUG-2008 Summary: (provided by applicant): Hepatitis C virus (HCV) infection is the main cause of chronic liver diseases in the US. Current antiviral treatments only cure the infection in half of the patients. The remaining patients often develop progressive hepatic fibrosis, leading to cirrhosis and hepatocellular carcinoma. These patients are sensitive to the hepatotoxic effects of alcohol, since moderate alcohol consumption accelerates fibrosis progression. Unfortunately, there are no effective antifibrotic treatments for patients with chronic liver diseases. The overall goal of this project is to define the mechanisms by which HCV leads to liver fibrosis and to identify potential targets of therapy. We will also investigate the mechanisms by which alcohol consumption aggravates the effects of HCV. We will use recently developed tools to express the HCV in the mouse liver and in liver cells and a well-characterized model of alcohol-induced liver injury. This proposal is based on several underlying hypotheses: 1) HCV directly interacts with hepatic stellate cells (HSCs), the main fibrogenic cell type, to induce liver fibrosis; 2) Fibrogenic products from hepatocytes expressing the HCV replicon induce fibrogenic actions in HSCs; 3) Alcohol administration induces the development of liver fibrosis in transgenic mice expressing the whole HCV genome; and 4) HSCs isolated from patients with HCV induced liver cirrhosis show phenotypical and functional features of activated HSCs and non-parenchymal liver cells are infected by HCV in patients. The specific aims to be

addressed in this project are: 1) To determine whether HCV proteins induce fibrogenic actions in primary cultured HSCs; 2) To determine whether hepatocytes and lymphocytes expressing the HCV induce fibrogenic actions in HSCs; 3) To investigate the mechanisms by which alcohol consumption aggravates HCV-induced liver fibrosis; and 4) To investigate the phenotypical and functional features of HSCs isolated from patients with HCV-induced liver cirrhosis and whether non-parenchymal liver cells are infected by HCV in patients. The experimental design will use primary cultures of HSCs, cultured cells expressing the HCV genomic replicon, and transgenic mice expressing the whole HCV genome in the liver. By combining in vivo and in vitro studies, our goal is to discover new insights into the molecular pathogenesis of HCVinduced liver fibrosis.

Project Title: HEPATITIS C PATHOGENESIS & THE HUMAN GENOME Principal Investigator & Institution: Thomas, David D.; Professor; Medicine; Johns Hopkins University 3400 N Charles St Baltimore, Md 21218 Timing: Fiscal Year 2001; Project Start 30-SEP-1999; Project End 31-AUG-2004 Summary: Neither viral nor environmental factors explain the heterogeneous outcome of hepatitis C virus (HCV) infection. This and research on other chronic viral illnesses suggest host genomic polymorphisms are important. In the past, host-viral interaction has been difficult to investigate because of the complexity of both HCV pathogenesis and the human genome. However, the biology of HCV is unfolding and major technologic advances now make large-scale genotyping feasible. In this investigation, these new molecular tools are used to test the hypothesis that HCV pathogenesis, and in particular viral clearance and cirrhosis is influenced by the host genome. To accomplish this research, a DNA library will be constructed from subjects in four large HCVinfected cohorts, including 565 who have cleared viremia, 256 with cirrhosis, and more than one thousand with persistent viremia but no detectable cirrhosis. Polymorphisms in human leukocyte antigen alleles and putative pathogenic genes will be characterized and distortions in their frequency evaluated according to outcome. The molecular basis for observed associations will be further assessed coupling information on genetic linkage and HCV biology. Possible confounding factors (such as alcohol ingestion, HIV infection, or HCV genotype with cirrhosis) also will be examined using existing, detailed clinical databases. Success is anticipated at modest expense since experienced researchers will be using existing molecular tools to investigate large established cohorts.

Project Title: HEPATITIS C VIRAL QUASISPECIES WITHIN THE LIVER Principal Investigator & Institution: Di Bisceglie, Adrian M.; Professor of Internal Medicine; Internal Medicine; St. Louis University St. Louis, Mo 63110 Timing: Fiscal Year 2001; Project Start 30-SEP-1999; Project End 31-AUG-2004 Summary: This application proposes to examine the biological significance of liverspecific hepatitis C viral (HCV) quasispecies variants. HCV is a positive single-stranded blood-borne RNA virus which infects humans and may cause chronic liver injury including hepatitis, cirrhosis and hepatocellular carcinoma through chronic infection. The liver is the major site of replication of HCV although HCV RNA is also found in the blood of infected individuals. The genome of HCV varies considerably in nucleotide sequence from isolate to isolate, allowing HCV to be divided into genotypes and
48
Cirrhosis
subtypes. However, multiple isolates from a single infected individual may also have considerable variability in nucleotide and amino acid sequence, particularly within the hypervariable region (HVR1) of the envelope gene. HRV1 is a sequence of approximately 27 amino acids at the likely N terminus of the HCV E2 glycoprotein. Variations in HRV1 provide markers for identification and tracing of HCV quasispecies variants. Quasispecies arise because of the high error frequency associated with viral RNA replication and immune pressure appears to be a factor in their selection. Preliminary experiments conducted by the applicants have shown that a greater number of HCV quasispecies variants are found within the liver compared to serum, even allowing for differences in viral load and that some liver-specific variants appear to be present. The applicants hypothesize that an excess of HCV quasispecies variants are continually being produced by errors in replication of HCV RNA within hepatocytes, some of which are cleared from serum by neutralizing antibodies, leaving behind in the circulation those variants which have escaped immune clearance. The significance of these differences will be examined through cloning and sequencing quasispecies variants present in both serum and liver. Changes in HCV quasispecies over time will be sought by comparing nucleotide sequence in HRV1 region before and after liver transplantation. The presence of possible neutralizing antibodies in serum directed against liver-specific quasispecies variants will be sought by enzyme-linked immunoassays based on peptides synthesized according to nucleotide sequences of the various cloned quasispecies. In addition, immunoreactivity to the whole of the E1 and E2 proteins cloned and expressed in mammalian cells will be determined. Differences in presence, titer and reactivity of antibodies against quasispecies will be compared to determine whether neutralizing antibodies account for clearance of some quasispecies from serum but not liver. These studies have great potential significance for understanding of viral clearance, development of persistent infection and for the development of a vaccine against HCV.

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
Studies
49
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 •
Project Title: HGF AND HEPATOCYTES IN NEOPLASIA AND LIVER FAILURE Principal Investigator & Institution: Michalopoulos, George K.; Professor and Chairman; Pathology; University of Pittsburgh at Pittsburgh 350 Thackeray Hall Pittsburgh, Pa 15260 Timing: Fiscal Year 2001; Project Start 15-AUG-1981; Project End 31-MAY-2002 Summary: In this renewal application we designed experiments aimed to capitalize on two major advances which occurred during the last funding period; 1. HGF biology: Hepatocyte Growth Factor (HGF) is now fully cloned and sequenced, in part from work funded by this grant in its earlier periods. Its receptor (encoded by the proto-oncogene c-met) is now well characterized. Activation of HGF by urokinase is now well documented. 2. In its new location in the university of Pittsburgh the lab has now access to hepatic tissue from the largest liver transplantation program in the world. Approximately 450 cases of liver at end stages of disease is available annually. The lab has now access to an existing collection of frozen tissue and paraffin blocks from hundreds of well defined stages of human hepatic disease. It also has access to all the new livers resected from transplantation cases. The project is now focusing on utilizing the new knowledge on HGF biology and the access of human liver tissues to focus on two lethal forms of human liver disease where growth disregulation leads to death: A. Hepatocellular Carcinoma (HCC). This is the most frequent cancer in the world. HGF is mitogenic and motogenic in normal human hepatocytes but is only motogenic and sometimes mitoinhibitory in human hepatocellular carcinomas. We will examine the role of HGF as a mitogen, motogen and mitoinhibitor in the evolution of human hepatocellular carcinoma from its earliest stages (atypical adenomatous hyperplasia, (AAH) seen as solitary nodules in cirrhosis), to its most advanced widely invasive forms. The role of HGF activation by urokinase in the evolution of this disease will be also examined. The potential mitoinhibitory effects of HGF on HCC, if properly

Cirrhosis
documented understood, may have a therapeutic potential in this disease. B. Fulminant liver Failure (FHF): In this condition, hepatocyte regeneration ceases, stem cell compartment (ductular hepatocytes) becomes activated, solitary clonal growths of hepatocytes (pseudoadenomas) grow to a hugh size. HGF levels in the plasma are extremely high. We will investigate; a. the role of HGF as a mitogen, motogen and morphogen in the evolution of new cell populations in this disease; b. the role of high doses of HGF in the inhibition of hepatocyte regeneration (leading to death of the patient); c. the effect of high doses of HGF in the activation of the stem cell compartment in the human liver.

Project Title: IDENTIFICATION OF HEPATITIS C VIRUS BINDING PROTEINS Principal Investigator & Institution: Gale, Michael J.; Assistant Professor; Microbiology; University of Texas Sw Med Ctr/Dallas Dallas, Tx 753909105 Timing: Fiscal Year 2003; Project Start 01-APR-2003; Project End 31-MAR-2005 Summary: (provided by applicant): Hepatitis C virus (HCV) is a hepatotropic RNA virus that infects more than 200 million people worldwide. HCV is transmitted via percutaneous exposure to contaminated blood or blood products. Acute exposure to HCV most often leads to chronic infection characterized by persistent virus replication, hepatitis and the development of fibrosis and cirrhosis. The molecular basis for the hepatotropism of HCV has not been defined, in part, because of the lack of a suitable culture system by which to propagate native HCV infection. HCV binding and entry into the host cell is thought to occur through specific interactions of the HCV surface glycoproteins, E1 and E2, with surface proteins expressed on the target cell. We have adapted and developed new strategies by which to identify candidate HCV receptor proteins, and by which to assess the role of each candidate receptor in mediating the processes of virus binding and entry that direct HCV infection. We will utilize these novel strategies to investigate the hypothesis that HCV tropism is mediated by E1 and/or E2 glycoprotein interactions with liver-specific cell surface receptor proteins. In Aim 1 of this proposal we will utilize a cell-based expression/binding assay system to screen a liver-specific cDNA library for candidate cellular receptors that bind to one or both HCV glycoproteins. Aim 2 will employ a novel HCV-pseudotyped virus system to assess the role of each candidate receptor protein in supporting HCV binding and entry into the host cell. This pilot project will identify cellular HCV-binding proteins that direct viral tropism and that participate in the processes of HCV binding and entry. The proposed studies will provide novel insights into the HCV infectious cycle, and will establish a foundation for future work aimed at understanding the virus-cell interactions that confer HCV tropism and infection.

Project Title: IDENTIFYING DETERMINANTS OF HCV TROPISM Principal Investigator & Institution: Dragic, Tatjana; Assistant Professor; Microbiology and Immunology; Yeshiva University 500 W 185Th St New York, Ny 10033 Timing: Fiscal Year 2003; Project Start 30-SEP-2003; Project End 31-MAR-2008 Summary: (provided by applicant): It is estimated that 170 million people worldwide are infected with the Hepatitis C virus (HCV) and are at risk of developing chronic hepatitis or cirrhosis, the latter often leading to hepatocellular carcinoma. There is currently no vaccine and licensed therapies are associated with modest efficacies and significant toxicities. Despite the urgency of this worldwide public health problem, our

51
basic understanding of HCV replication and pathogenesis remains poor due to a lack of key experimental models. For example, difficulties in culturing the virus in vitro and expressing native, fusogenic envelope glycoproteins have greatly limited studies of HCV tropism and entry. These are critical aspects of viral biology because the host range and pathogenesis of enveloped virus infection is largely determined by the selective interaction of viral envelope glycoproteins with cell-surface receptors. A major goal in HCV research is to understand how HCV targets the liver and by what mechanism it enters host cells. Recently, a major breakthrough in the field has been the development of retroviruses pseudotyped with HCV envelope glycoproteins that specifically mediate infection of primary hepatocytes, as well as certain other human cells. We will use this new experimental system to study HCV entry into target cells. Alterations in naturally occurring HCV envelope glycoproteins may predicate differences in receptor usage and target cell tropism in vivo. To investigate the range of HCV cellular tropism, pseudotypes incorporating envelope glycoproteins from clinical HCV isolates will be tested for their ability to enter relevant primary cells and cell lines. A functional cDNA cloning approach will be used to identify cell-surface receptors that specifically mediate HCV entry into different target cells. However, these receptors may be ubiquitously expressed and HCV targeting to different cell types may be determined by another mechanism. We recently demonstrated that L-SIGN and DC-SIGN are specific HCVcapture receptors and we will explore whether they mediate infection of target cells in trans, thereby determining HCV tropism. The major objective of our work is to identify the basic protein interactions that mediate HCV tropism, which will serve as a foundation for detailed structure/function analyses of HCV receptors and envelope glycoproteins.

Project Title: IMMUNE RESPONSES AND ACHOHOLIC LIVER DISEASE Principal Investigator & Institution: Jerrells, Thomas R.; Professor; Pathology and Microbiology; University of Nebraska Medical Center Omaha, Ne 681987835 Timing: Fiscal Year 2001; Project Start 01-APR-1999; Project End 31-MAR-2003 Summary: (Adapted from the Investigator's Abstract) Alcoholic liver disease (ALD) is a serious consequence of alcohol abuse and results in a great deal of morbidity and mortality in the United States. The mechanisms that lead to ALD are poorly understood, and it is not known what factors are involved in the susceptibility for the development of ALD. The prevailing opinion is that some factor initiates an inflammatory response in the liver that is uncontrolled and ultimately results in the characteristic fibrosis associated with this process. Data from this laboratory have shown that a condition that resembles the sequence of events in ALD can be initiated in ethanol (ETOH)-fed C57Bl/6 mice after activation of T-lymphocytes by specific antigen or concanavalin A. These activation stimuli induce steatosis and hepatitis only in ETOH-fed mice, which ultimately result in liver damage evidenced by elevated serum levels of ALT and AST. These data support our suggestion that at least one factor involved in initiation and development of ALD is a specific immune response in the liver. To test this hypothesis we propose to use these murine models of ALD and a model of viral hepatitis to define the mechanisms responsible for this immune - mediated liver damage. It is our specific hypothesis that initiation of the inflammatory process is the result of specific T cellmediated killing, either through direct cellular cytotoxicity or through the production of cytotoxic cytokines of the infected hepatocyte. Further, we hypothesize that corticosteroid production associated with ETOH consumption has a twofold effect in this system. First, the immune response is suppressed by corticosteroids to inhibit the
52
Cirrhosis
ability to control the replication of the infectious agents, results in more inflammation. Second, corticosteroids sensitizes hepatocytes to enhance destruction of these cells by either direct T-cell-mediated lysis or lysis mediated by inflammatory cytokines such as tumor necrosis factor. The proposed research will also define the specific cells that initiate or mediate liver damage as well as the role of the inflammatory response and inflammatory cytokines in these models of experimental ALD.

Project Title: IMMUNOGENICITY OF HEPATITIS C VIRUS (HCV) LIKE PARTICLES Principal Investigator & Institution: Barber, Glen N.; Associate Professor; Microbiology and Immunology; University of Miami Box 248293 Coral Gables, Fl 33124 Timing: Fiscal Year 2003; Project Start 01-AUG-2003; Project End 31-JAN-2008 Summary: (provided by applicant): Hepatitis C virus [HCV], a member of the Flaviviridae, is a major cause of chronic hepatitis, liver cirrhosis and hepatocellular carcinoma. Acute infection with HCV is associated with persistent viral replication in approximately 80-90% of cases, with an estimated 200 million people infected worldwide. Presently, the only effective therapy against HCV infection is type I interferon [IFN] currently in combination with the nucleoside analogue ribavirin. However, response rates vary from 5% to 50%, depending on race and gender, thus leaving many infected individuals untreatable. Presently, there is no vaccine for HCV and therefore a collective need to develop preventive strategies as well as new therapies. The search for effective vaccines is hampered, however, by the inability to grow candidate HCV vaccine preparations in vitro and by the prevalence of numerous HCV quasispecies that have evolved due to the virus lacking a proof reading mechanism while replicating. Since HCV cannot be efficiently manufactured for vaccine assessment, we have synthesized, in mammalian cells, highly immunogenic, non-infectious HCVlike particles comprised of the core, E1 and E2 products of HCV. This was achieved by cloning the core/El/E2 genomic region of HCV into the relatively simple, nonpathogenic negative-stranded virus, vesicular stomatitis virus (VSV). Following infection of tissue cultured mammalian cells with VSV/HCV recombinant viruses, high levels of authentic core/El/E2 HCV proteins were generated that autoassembled into HCV-virus-like particles (VLPs). Importantly, our preliminary data further indicates that VSV/HCV induced cell-mediated and humoral activity to all the structural proteins in immunized mice. Thus, our HCV expression system may have the capacity to generate effective, multivalent immune respones to a variety of HCV encoded proteins. Given this data, we aim to analyze the potency of the rVSVs system that expresses HCV gene products or purified HCV-like particles themselves, in vaccine studies designed to further evaluate whether robust cell-mediated and humoral responses can be safely and effectively obtained to multiple HCV epitopes.

hemophiliacs, both HIV(+) and HIV(-). Approximately 826 HCV-infected hemophiliacs from 10 U.S. hemophilia treatment centers will be available for study. This group is unique in that patients are well characterized, closely followed, the time of HCV infection is known, HCV infection duration is greater than 20 years, and the incidence of liver disease progression is increasing. The specific objectives of this study include: (1) a cross-sectional cohort study in which hemophiliacs with HCV infection, both HIV(+) and HIV(-), are enrolled and undergo transjugular liver biopsy to determine the prevalence of cirrhosis and fibrosis progression rate. (2) a cross-sectional study comparing HCV-infected patients, both HIV- and HIV+, to determine clinical, life-style, and laboratory, e.g. biochemical, serologic, molecular biologic, and immunologic characteristics associated with development of cirrhosis and stage of fibrosis progression. (3) a cytokine study, comparing cytokine mRNA levels, interleukin-6 (IL-6), interleukin-10 (IL-10), and transforming growth factor-beta (TGF-beta 1 and TGF-beta 2) in liver tissue, cytokine immunoassay levels in plasma, and cytokine expression genotypes with liver histopathologic score and with fibrosis progression rate in prospectively-biopsied hemophiliacs.

HEPATIC
STELLATE
CELL
Principal Investigator & Institution: Luxon, Bruce A.; Associate Professor; Internal Medicine; St. Louis University St. Louis, Mo 63110 Timing: Fiscal Year 2003; Project Start 01-JUN-2003; Project End 31-MAR-2007 Summary: (provided by applicant): This proposal has the long term goal to elucidate the role that integrins have in hepatic stellate cell activation and hepatic fibrosis. Hepatic stellate cells are responsible for producing most of the extracellular matrix components ("scar" tissue) found in a wide variety of hepatic diseases. Stellate cells in normal liver are "quiescent" (non-scar forming) but undergo a process called "activation" in which they begin to proliferate and synthesize fibrous tissue leading to cirrhosis. Integrins are receptors located on the cell surface of stellate cells that allow the stellate cells to interact with the hepatic extracellular matrix. Specific extracellular matrix proteins are known to bind to the integrins and cause multiple signals to be sent to the stellate cell, inducing them to activate. The hypothesis to be tested in this series of experiments is that integrins (especially the fibronectin receptor alpha-5 beta-1) modulate and perpetuate the activation of hepatic stellate cells through their interaction with the extracellular matrix. To test this hypothesis, the following specific aims will be completed:1). Determine the mechanisms by which stellate cells control the expression of active integrin receptors on their cell surface. 2). Determine the mechanisms of integrin signaling during activation of stellate cells. 3). Determine if interrupting integrin signaling can block the perpetuation step of stellate cell-mediated fibrogenesis. These studies are designed to unravel the molecular mechanisms involved in integrinmediated activation of stellate cells. Understanding the complex array of integrin interactions, modulations, and signaling events may elucidate potential mechanisms that can be therapeutically targeted to stop the fibrogenesis that occurs in chronic liver disease.

Timing: Fiscal Year 2001; Project Start 01-NOV-1990; Project End 31-MAY-2005 Summary: Role of Lipid Peroxidation in ALD: The long-term goal is to determine the pathogenesis of alcoholic liver disease (ALD). Specific Aims are: 1) To determine the role played by 26s proteasome peptidase inhibition in the protein retention in hepatocytes in experimental ALD in the rat and mouse. 2) To determine the role played by the 20s proteasome peptidase inhibition in the removal of oxidized proteins in hepatocytes in experimental ALD. 3) To determine at the individual liver cell level, using in situ assessment of the phosphorylation-ubiquitin- proteasome pathway, whether the proteasome function is damages in ALD. The studies will focus on correlations made between histopathology, immunohistochemistry and biochemical measurements made on the livers of rats and mouse fed ethanol intragastrically for 2-4 months when significant alterations of liver histology has developed. The basic concept to be tested is that oxidative stress and free radical induced injury initiates a change in protein turnover in the liver cell which shifts the balance between protein synthesis and protein elimination in the liver cell where the net result is protein retention and cell enlargement. Mice deficient in or over expressing CYP2E1 will be studies using the intragastric ethanol feeding model in order to better access the role of CYP2E1 in the pathogenesis of liver cell protein retention in experimental ALD. The mechanism which accounts for the up regulation of CYP2E1 and other proteins retained in the liver cytosol will be identified. In this way the pathogenesis o liver cell enlargement will be determined and the role that this phenomenon plays in ALD will be defined.

Project Title: LIVER CENTER Principal Investigator & Institution: Bissell, Dwight M.; Professor; Medicine; University of California San Francisco 500 Parnassus Ave San Francisco, Ca 94122 Timing: Fiscal Year 2001; Project Start 01-JUL-1985; Project End 31-MAY-2002 Summary: The liver plays a central and complex role in health, being responsible for synthesis of key molecules, maintenance of metabolic balance, and detoxification processes. Liver diseases are among the leading causes of death in the United States and their investigation spans basic science and clinical medicine. At the University of California, San Francisco, the liver is a major focus of study among scientists in fifteen Departments and two Schools (Medicine and Pharmacy) and is represented on three major campuses of the University (Moffitt-Long Hospital, San Francisco General Hospital, and the Veterans Affairs Medical Center). With the recent incorporation of Mt. Zion Medical Center among the UCSF campuses, it is anticipated that Center programs will eventually include investigators at that site as well. The Liver Center was established in 1975, assuming its current Core Center format in 1980, for the purposes of melding individual research programs into a consortium and of fostering interdisciplinary research through support of core facilities, funds for new initiatives, enrichment activities (including visiting scientists and mini-sabbatical programs), and the highly successful annual retreat. Center Core Facilities, among them Animals, Molecular Biology, Liver Cell Culture, Liver Perfusion, Microscopy, Biostatistics, and Mass Spectrometry, have provided important services to Center investigators during the present funding period. New research directions have emerged, and current areas of emphasis include basic and clinical studies in cell biology, drug metabolism and toxicity, hepatic fibrosis and cirrhosis, immunology and transplantation, metabolism, transport, bile secretion, and viral hepatitis. The research base has grown substantially, reflecting the favorable influences of several factors, including strong institutional commitment, continued successful operation of the liver transplantation program, and

increasing interdisciplinary collaboration. Goals for the next funding period include further expansion of the use of molecular and genetic experimental approaches and the facilitation of clinical research, including the study of human materials. To this end, proposed major changes in core facilities include expansion of the Molecular Biology Core Facility, and establishment of a new Clinical and Biostatistics Core Facility. Dr. D.M. Bissell, currently a Center Associate Director, will assume the role of Co-Director. The Center enjoys the ongoing support of the leadership at UCSF, where it continues to be recognized for major contributions to digestive diseases research and serves as a national resource in providing rare animals or reagents and training in specialized techniques. It is anticipated that, during the next five years, the Center will facilitate increasing clinical and laboratory application of molecular approaches to address specific issues in human liver biology and disease, including studies of the pathogenesis of tumors and non-neoplastic disorders, development of diagnostic methods and reagents, and innovations in medical and surgical treatment.

Project Title: MEDIATORS OF PULMONARY VASODILATATION IN LIVER DISEASE Principal Investigator & Institution: Fallon, Michael B.; Associate Professor; Medicine; University of Alabama at Birmingham Uab Station Birmingham, Al 35294 Timing: Fiscal Year 2001; Project Start 01-SEP-2000; Project End 31-AUG-2004 Summary: Endothelial dysfunction underlies the vascular abnormalities of chronic liver disease and is characterized by changes in the levels and activity of endothelial nitric oxide synthase. How these changes occur and why there is variability in the vascular beds involved is incompletely characterized. The hepatopulmonary syndrome is one important vascular complication of liver disease where 15-20 percent of patients with cirrhosis develop pulmonary microvascular dilatation leading to hypoxemia. No effective medical therapies are available. Experimental biliary cirrhosis reproduces the pulmonary vascular and gas exchange abnormalities of human hepatopulmonary syndrome in association with an increase in pulmonary microvascular endothelial nitric oxide levels and activity. Pre-hepatic portal hypertension alone does not cause pulmonary vascular or endothelial nitric oxide synthase alterations, implying that mediators released during hepatic injury may trigger endothelial alterations in the lung. Hepatic and plasma endothelin-1 levels rise and correlate directly with the degree of intrapulmonary vasodilatation in experimental biliary cirrhosis and preliminary studies reveal that chronic low level endothelin-1 infusion in pre-hepatic portal hypertensive animals results in selective pulmonary microvascular dilatation. Although classically recognized as a vasoconstrictor, circulating endothelin-1 stimulates endothelial cell endothelial nitric oxide synthase activity and can cause vasodilatation. Our hypothesis is that endothelin-1, released into the circulation during liver injury, preferentially activates pulmonary vascular endothelial nitric oxide synthase and triggers pulmonary microvascular dilatation. To test this hypothesis our specific aims will 1) define the effects of chronic endothelin-1 infusion on the development of intrapulmonary vasodilatation and endothelial nitric oxide synthase expression and activity in normal, pre- hepatic portal hypertensive and biliary cirrhotic animals in vivo 2) assess the effects of exogenous emdothelin-1 on endothelial nitric oxide synthase expression and activity in isolated pulmonary vascular segments and endothelial cells from normal, pre-hepatic portal hypertensive and biliary cirrhotic animals and 3) directly measure the effects of exogenous endothelin-1 on pulmonary microvascular reactivity in normal, pre-hepatic portal hypertensive and biliary cirrhotic animals. Our long-term goal is to use an

understanding of endothelial dysfunction in hepatopulmonary syndrome to develop specific medical therapies and as a paradigm for understanding the pathogenesis of other vascular complications of liver disease. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen •
Project Title: MITOCHONDRIAL GSH /SAM IN ALCOHOL INDUCED LIVER DAMAGE Principal Investigator & Institution: Fernandez-Checa, Jose C.; Fundacio Clinic C/Villarroel 170 Barcelona, Timing: Fiscal Year 2002; Project Start 30-SEP-2002; Project End 31-AUG-2005 Summary: (provided by applicant): Since we first discovered in 1987 the depletion of mitochondrial GSH (mGSH) status by chronic ethanol intake, considerable progress has been made regarding the molecular mechanism(s) of the defect and its functional impact in alcohol-induced liver damage (ALD). In addition to the altered regulation of mGSH by alcohol, S-adenosyl-L-methionine (SAM) depletion has been also reported and is thought to contribute to the progression of the disease. GSH and SAM may exhibit parallel features as both are found in mitochondria due to specific transport mechanisms. Thus, the present proposal will look at the specific regulation of mitochondrial SAM (mSAM) pool by alcohol and the temporal and functional relationship between mGSH and mSAM by alcohol. 1. - SAM levels and transport in rat liver mitochondria from alcohol-fed rats. Most studies have reported the status of total SAM levels in hepatocellular extracts in patients and experimental models of ALD. We wilt examine the status of mSAM levels and its mitoehondrial transport in chronic alcohol-fed rats. 2. Temporal and functional relationship between mitochondrial GSH and SAM depletion by alcohol: Role of Kupffer cells and liver steatosis. We will examine if mGSH depletion by alcohol precedes or follows that of SAM (total and mSAM) in mitochondria from alcohol fed rats and its relationship with pathology. The role of Kupffer cell activation and liver steatosis on alcohol-mediated mGSH and total SAM (cytosol and mSAM) depletion will be evaluated in alcohol-fed rats and in a model of non-alcohol: hepatic steatosis. 3. Mechanism whereby SAM feeding normalizes the alcohol-altered mitoehondrial membrane fluidity and mGSH transport. Increasing evidence indicate a critical role of cholesterol/phospholipid molar ratio in the regulation of mitochondrial membrane mieroviseosity and mGSH transport, in addition to these changes, we wilt examine the regulation and trafficking of cholesterol into mitoehondria, as well as the fatty acid composition of individual lipids of mitochondrial lipid classes from chronic alcohol-fed rats with or without SAM supplementation. 4. Regulation of MAT1A by glycosphingolipids and sphingomyelinases. TNF and shortchain ceramide have been reported to downregulate the expression of MAT1A. Since sphingomyelinases (SMases) are known to mediate some of the effects of TNF, we will examine the role of individual neutral or acidic SMase, in the regulation of MATIA in primary cultured rat hepatocytes and HepG2 cells exposed to exogenous neutral (NSMase) or acid (ASMase) SMases. In addition, we will assess the role of TNF on MATIA expression in ASMase knockout mice. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen

Timing: Fiscal Year 2001; Project Start 01-APR-1999; Project End 31-MAR-2003 Summary: Alcohol-induced liver cirrhosis is one of the major causes of death worldwide. Strong evidence has established that acetaldehyde, ethanol's first metabolite, is fibrogenic per e and enhances type I collagen production by hepatic stellate cells. Despite major efforts by several laboratories, relatively little is known pertaining the molecular events underlying this stimulatory effect. Thus, it is our long-term goal to integrate cellular and molecular events into a unified picture that explains how acetaldehyde stimulates type I collagen gene transcription in the liver. The specific aims of this proposal: 1) To characterize the cis-regulatory elements and trans-acting factors, active in hepatic stellate cells of human origin, mediating acetaldehyde-induced human alpha2(I) collagen gene up-regulation; 2) To elucidate key molecular mechanisms by which acetaldehyde modulates the activity and/or binding of the transcription factors that interact with the acetaldehyde- responsive element of the human alpha2(I) collagen gene; and 3) To determine whether acetaldehyde stimulates human alpha2(I) collagen gene expression directly, or through an autocrine loop involving enhanced production and/or activation of transforming growth factor-beta in human hepatic stellate cells. A better characterization of the molecular events underlying enhanced COL1A2 gene expression in hepatic stellate cells, will enhance our understanding of the pathophysiology of ethanol- induced liver fibrosis, and will allow in the near future, to develop new therapies aimed at counteracting the devastating effects of this disease.

Project Title: MULTICENTERED RANDOMIZED TRIAL OF HIGH-DOSE URSO IN PSC Principal Investigator & Institution: Lindor, Keith D.; Professor and Director; Mayo Clinic Rochester 200 1St St Sw Rochester, Mn 55905 Timing: Fiscal Year 2001; Project Start 01-SEP-2001; Project End 31-AUG-2006 Summary: (provided by applicant): Primary sclerosing cholangitis (PSC) is a progressive chronic cholestatic liver disease of unknown etiology that is commonly associated with chronic colitis. PSC, a common liver disease among adults, usually leads to advanced liver disease and liver failure, and as such, is an important indication for liver transplantation. Unfortunately, no effective medical therapy currently exists for PSC. The group of investigators has a longstanding track record of clinical trials in chronic cholestatic liver disease, particularly in primary sclerosing cholangitis. Recently we have generated promising results from a pilot study using high doses of ursodeoxycholic acid in the treatment of PSC. Lower doses of ursodeoxycholic acid in patients with PSC led to biochemical improvement but did not affect other clinically important endpoints in a previous study. Our pilot data is supported by data from another group showing in a small, randomized trial that high dose ursodeoxycholic acid led to biochemical, histologic, and cholangiographic improvement compared to placebo at two years. In this submission, we propose a large-scale multi-center placebo-controlled randomized trial with a minimum follow-up of four years for 150 patients with primary sclerosing cholangitis. Primary endpoints of the study will include histologic progression to cirrhosis, development of esophageal or gastric varices, need for liver transplantation, and survival. Secondary endpoints will include measurements of the effects of urosodeoxycholic acid (28-30 mg/kd/d) on liver biochemistries, histologic stage, cholangiographic features, Mayo risk score, and quality of life, using validated questionnaires. This study will be the largest ever conducted in PSC and the follow-up will be the most extensive. This will provide an invaluable resource for studying the natural history of this disease and as part of this study we will also collect serum, cells

for extraction of DNA, bile, and tissue from the liver and colon as a resource for future studies. The multi-centered nature of this trial will allow recruitment of patients into this study from a diverse patient population, representative of the gender and racial distribution of this disease. Chances of successful completion of this study are enhanced by the large PSC patient population that the participating centers currently manage, recognition of these sites as referral centers for new patients with PSC, as well as a longstanding track record in clinical trials in cholestatic liver disease.

Project Title: NATURAL HISTORY OF HEPATITIS C INFECTION IN HIV DISEASE Principal Investigator & Institution: Horsburgh, Charles Robert.; Boston Medical Center Gambro Bldg, 2Nd Fl, 660 Harrison Ave, Ste a Boston, Ma 02118 Timing: Fiscal Year 2002; Project Start 30-SEP-1999; Project End 31-AUG-2004 Summary: Each year more than 20 percent of the 3.5 million Americans infected with hepatitis C progress to cirrhosis and ten to fifteen thousand develop end-stage liver disease. Because hepatitis C and HIV disease share common modes of transmission, coinfection occurs in 8-10 percent of all HIV-infected individuals overall and is present in over 70 percent of those with parenteral risk factors. There are few data available on the natural history of HIV and HCV co-infection in specific risk groups, as most previous studies have not assessed the impact of confounding variables such as alcohol use, continuing substance abuse, malnutrition, duration of HCV infection, and degree of HIV-related immune suppression. Moreover, current data regarding the impact of HIV on HCV infection are changing rapidly due to the widespread use of highly active antiretroviral therapy (HAART). New cases of HIV and HCV are expected to continue to occur in substance abusers, since HIV infection is increasing rapidly in inner-city populations. The purpose of this study is to examine the natural history of HIV and HCV co-infection in a large inner city cohort who are predominately minority and have a history of polysubstance abuse. We will compare three groups: 1) HIV and HCV infected, 2) HCV infected alone, and 3) HIV infected alone. Epidemiologic studies will be conducted to explore the risk factors associated with HCV progression, morbidity, and mortality, using both standard clinical parameters and novel surrogate markers of liver fibrosis. Additional targeted substudies will examine the important clinical question of whether therapy of either the HCV or HIV disease alters progression of liver disease. Finally, immunologic studies aimed at increasing our understanding of the pathogenesis of liver injury and why it may be accelerated in HIV disease will be performed. The central hypothesis of this proposal is that alterations in immune function associated with HIV infection are the main determinant of poorer hepatitis C outcomes. The specific aims of this grant are: 1) to identify the variable(s) that impact the progression of HCV infection in HIV-infected individuals; 2) to determine the effect of HAART on HCV in dually infected persons; and 3) to define the immunologic variables that predict more rapidly progressive liver disease. These studies are expected to improve our understanding of the natural history and pathogenesis of HCV in immunosuppressed hosts. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen

Timing: Fiscal Year 2001; Project Start 30-SEP-1999; Project End 31-AUG-2004 Summary: (adapted from the application) Hepatitis C virus (HCV) infection and its complications are emerging as an extraordinarily important public health problem worldwide. Hepatocellular carcinoma (HCC) is now a firmly established and largely incurable complication of chronic HCV, and its prevalence in this country will continue to grow as a large cohort of patients infected decades ago comes to clinical attention. While most cases appear to arise in the setting of chronic inflammation, cirrhosis, and regeneration, the pathogenesis of HCV-related HCC remains unknown. It becomes apparent that a fundamental understanding of the mechanisms of HCV-related hepatocarcinogenesis is essential to effectively address this major sequel to chronic infection. Animal models of HCV-related hepatocarcinogenesis have been difficult to construct, in great part because of the obstacles to creation of a model permissive for infection. Transgenic mouse models permit the opportunity to examine the effects of selective expression of viral proteins. A recent report has suggested that transgenic mice expressing the HCV core protein alone develop HCC. We have created a transgenic mouse model that successfully expresses HCV core as well as the two envelope glycoproteins; however, these animals do not develop liver disease. The basis for these observed differences is unknown. We propose to explore the contributions of three major arms -to HCV-related HCC: (1) viral protein expression; (2) host genetic predisposition; and (3) the host immune response. To accomplish this, we will use novel transgenic mouse models to explore the direct contribution of both HCV structural to explore the mechanistic differences between our model and the core model. We will also cross our transgenic HCV structural protein mice with a recently developed mutant tumor suppressor gene mouse model that spontaneously develops HCC in a large portion of aging animals. This cross will allow us to "read out" the contribution of viral protein expression to HCC development (by increased frequency or acceleration of HCC formation), as well as to determine whether HCV-induced HCC requires a host genetic predisposition- Finally, we will create a novel, inducible transgenic model that expresses the full length HCV polyprotein to explore the contribution of activation of the host immune system to HCV-related hepatocarcinogenesis. Together, these models will help provide insights into the factors responsible for this devastating complication of chronic HCV infection.

Principal Investigator & Institution: Groopman, Jerome E.; Chief; Beth Israel Deaconess Medical Center St 1005 Boston, Ma 02215 Timing: Fiscal Year 2001; Project Start 30-SEP-2001; Project End 31-AUG-2006 Summary: (provided by applicant) The primary objective of this proposal is to examine how the hepatitis C virus (HCV) and the human immunodeficiency virus (HIV) envelope proteins may act collaboratively to trigger signaling events that contribute to hepatocyte inflammation and apoptosis. Coinfection with HIV and HCV confers a poor prognosis, with progressive hepatic dysfunction that often results in cirrhosis and death. Both intravenous drug users and hemophiliacs have a high incidence of coinfection and face this grim outcome. Why do coinfected hosts have such high rates of progressive liver disease? The pathogenesis of HCV-related hepatitis is believed to be due, in part, to immune-mediated inflammation as well as the effects of direct infection of hepatocytes. Our preliminary data suggest a novel third potential mechanism for hepatic inflammation and apoptosis. We observed in both HepG2 cells and primary
60
Cirrhosis
hepatocytes that treatment with the HCV envelope protein E2, in conjunction with HIV gpl20, induced the inflammatory chemokine interleukin-8 (IL-8) and triggered apoptosis. These functional outcomes occurred at nanomolar concentrations of E2 and gp 120 that correspond to the Kd's for the cognate ligands binding to their respective receptors, CDS1 and CXCR4, and were associated with activation of specific signaling molecules, including the Src family Lyn kinase, RAFTK/Pyk2, Erkl/2 and p38 MAP kinases, and Fas-ligand. These data indicate that proinflammatory and apoptotic events may occur due to dual exposure to HCV and HIV envelope proteins via an "innocent bystander" mechanism. This proposal seeks to characterize the molecular mechanisms of IL-8 induction and the program of apoptosis caused by HCV E2 and HIV gpl20. A focused experimental approach is presented to delineate signaling events that originate at specific cell surface receptors, are transduced through intermediate signaling molecules, and converge on transcriptional activators of the MAP kinase family. Elucidating how these HCV and HIV envelope proteins may interact with hepatocytes could not only further our understanding of the pathogenesis of disease in coinfected hosts but also lead to targeted therapeutic strategies to improve the currently poor prognosis of such individuals.

Project Title: PATHOGENESIS OF LIVER DISEASE IN HEPATITIS Principal Investigator & Institution: Chisari, Francis V.; Professor & Head; Scripps Research Institute 10550 N Torrey Pines Rd La Jolla, Ca 920371000 Timing: Fiscal Year 2003; Project Start 01-JUL-1983; Project End 31-DEC-2007 Summary: (provided by applicant): The hepatitis B virus (HBV) is a non-cytopathic, hepatotropic DNA virus that causes acute and chronic hepatitis and kills a million people each year from cirrhosis of the liver and hepatocellular carcinoma. Understanding the mechanisms responsible for viral clearance, persistence and disease pathogenesis during HBV infection is, thus, scientifically and medically important. We have previously shown that the immune response plays a key role in the outcome of HBV infection in humans; and we have used transgenic mice to identify immunological mechanisms that are probably responsible for viral clearance and liver disease. In the current funding interval, we used acutely infected chimpanzees in order to study the early host-virus interactions that occur at the site of infection and likely determine its outcome but, for practical and ethical reasons, aren't accessible in man. Those results indicate that the course and duration of HBV infection are clearly related to the kinetics and extent of viral spread, and to the kinetics, magnitude, quality and cytokine profile of the intrahepatic T cell response. In the next funding interval we will determine which of these factors actually decide the outcome of HBV infection by selectively regulating viral spread, the cellular immune response, inflammatory cytokines, and expression of a putatively immunosuppressive HBV protein in acutely infected chimpanzees. The results of these experiments should establish the basis for viral clearance, persistence and disease pathogenesis in acute and chronic HBV infection, and thereby identify new therapeutic strategies to, hopefully, cure this deadly disease.

Studies
61
Timing: Fiscal Year 2001; Project Start 01-JUN-1998; Project End 31-MAY-2003 Summary: APPLICANT'S ABSTRACT: Alcoholic Cirrhosis is the most common reason for liver failure and the largest diagnostic category receiving liver transplantation. However, factors that shape policy, treatment choices, candidate selection, and public options are strongest against this group. Without guidance from rigorous research data, the future for alcohol cirrhotics pursuing transplantation is uncertain. To date, no studies of outcome in alcoholic cirrhotics have used alcohol research measures or models, as proposed herein. In the transplant literature there is a lack of consistency in relapse definitions, timing or methods of follow-up, or use of post-transplant factors to predict alcohol use. This proposed research will expand the primary aim of alcohol research which is to identify and explain the factors that shape alcohol use and its consequences in various populations. To investigate outcome in alcoholic cirrhotics undergoing liver transplantation, expertise in psychiatry, medicine, transplantation, and alcoholism is needed. The applicant, an M.D. board certified in psychiatry, has the basic requisite skills to embark on this line of research. Through five years of clinical work evaluating, treating, and following alcoholic cirrhotic patients pursuing transplantation the applicant has developed a high degree of clinical acumen as well as the necessary connections to one of the largest liver transplant teams in the U.S. This Mentored Clinical Scientist Development Award will allow the applicant the opportunity to consolidate clinical skills in conjunction with a structured educational program and mentored research. During the award period, the candidate will conduct a prospective longitudinal study of alcohol use following liver transplantation, while investigating pre-transplant and post-transplant factors hypothesized to influence return to drinking. This research experience will be complemented by career development activities supervised by pioneering researchers in addictions, transplantation, and psychiatric research. The proposed plan is designed to develop the candidate's expertise in: 1) longitudinal study design and analysis; 2) alcohol relapse identification and monitoring; 3) conceptual and analytic modeling of relapse factors; and 4) post-transplant alcohol use outcome, and will give her the necessary skills to become an independent academic researcher in addictions and transplantation research.

Project Title: PROSTAGLANDIN THERAPY FOR ALCOHOLIC HEPATITIS Principal Investigator & Institution: Hill, Daniell B.; Associate Professor of Medicine; Medicine; University of Kentucky 109 Kinkead Hall Lexington, Ky 40506 Timing: Fiscal Year 2001; Project Start 01-MAR-2000; Project End 31-OCT-2001 Summary: Alcoholic liver disease (ALD) is an important health problem. There is increasing evidence that many of the clinical manifestations and, at least, part of the liver injury in ALD are mediated by cytokines such as tumor necrosis factor (TNF), interleukin-6 (IL-6) and interleukin-8 (IL-8). Regulation of these cytokines has become a focal point for therapeutic intervention in many diseases including ALD. Nuclear factor kappa B (NFkappaB) is a transcription factor for these cytokines. NFkappaB is activated by reactive oxygen intermediates and endotoxin. We postulate that chronic alcohol abuse causes increased gut permeability and endotoxemia, depletion of many nutrient antioxidants, inadequate macrophage prostaglandin concentrations, generation of reactive oxygen intermediates, activation of NFkappaB, increased TNF production, increased IL-8 production with neutrophil infiltration, mitochondrial dysfunction with mitochondrial GSH depletion, increased susceptibility to hepatic TNF cytotoxicity, and liver injury. The overall goals of my laboratory are to further characterize cytokine mediated nutritional/metabolic events and mechanisms of cytokine induced liver

injury, with the ultimate goal being the development of effective "anticytokine" therapy for ALD. The "anticytokine" therapy to be studied in this proposal is the prostaglandin E1 analogue misoprostol. We postulated that misoprostol will both inhibit cytokine production and improve gut permeability. The specific objectives of this proposal are: 1. Determine the dose of misoprostol that most effectively decreases ex vivo cytokine production when given orally for a 14 day period to normal volunteers. 2. Determine that the optimal dose of misoprostol that effectively decreases ex vivo cytokine production in normal volunteers also effectively decreases ex vivo cytokine production in patients with stable alcoholic cirrhosis and is well tolerated by them when given orally over a 14 day period. 3.A. Determined whether misoprostol treatment of patients with acute alcoholic hepatitis is well tolerated and effective in decreasing gut permeability, endotoxemia, plasma cytokine levels, ex vivo cytokine production and lipid peroxidation. 3.B. Determine the relationship between plasma cytokine levels and putative cytokine mediated clinical manifestations of alcoholic liver disease includings: measures of liver injury/function, neutrophilia/acute phase reactants, fever/metabolic rate and appetite/nutritional parameters.

Project Title: PROSTANOIDS AND LIVER MICROCIRCULATION IN STRESSES Principal Investigator & Institution: Zhang, Jian X.; Biology; University of North Carolina Charlotte Office of Research Services Charlotte, Nc 282230001 Timing: Fiscal Year 2003; Project Start 01-JUN-2003; Project End 31-MAR-2006 Summary: (provided by applicant): Endotoxemia is a common but severe complication of cirrhosis frequently causing liver injury and even organ failure. The mechanism underlying the increased susceptibility of the cirrhotic liver to endotoxemia in the sequential stresses, however, is not completely understood. Studies have shown a hepatic upregulation of constrictor endothelin (ET) and a decreased release of vasodilator nitric oxide (NO) in the cirrhotic liver. Our preliminary studies have shown that in cirrhosis, constrictor prostanoids are released in response to ET, and the action of the prostanoids is modulated by NO. We also showed that endotoxemia as a secondary stress caused an additional upregulation in already increased ET gene expression in the cirrhotic rat liver, but endotoxin-induced expression of inducible nitric oxide synthase was blunted by the preexisting cirrhosis. We therefore hypothesize that liver cirrhosis as a pre-existing condition primes the hepatic microcirculation for predisposition to an imbalance between constrictor and dilator influences by sensitizing the ET/constrictor prostanoids pathway and decreasing production of NO. We further hypothesize that endotoxemia as a secondary stress further activates the pathway leading to dysregulation of the hepatic microcirculation and ultimately hepatocellular injury. To test these hypotheses, three specific aims are proposed: 1) determine whether cirrhosis as a pre-existing condition primes the hepatic microcirculation for predisposition of an imbalance between constrictor and dilator influences by sensitizing the ET-mediated release of vasoconstrictor prostanoids; 2) determine whether endotoxemia as a secondary stress enhances the pressor response mediated by the release of vasoconstrictor prostanoids in response to ET; 3) determine whether an overwhelming increase in ET accompanied by the sensitization of ET-induced release of prostanoids and an attenuated expression in iNOS following the sequential stresses result in an imbalanced regulation of vasoconstriction and vasodilation and dysregulation of the hepatic microcirculation. This proposal not only will allow us to evaluate the role of constrictor prostanoids in regulation of hepatic microcirculation in cirrhosis and endotoxin-induced sequential stresses, but also will provide invaluable information on

Project Title: PROTEOMICS AND BIOMARKERS FOR HEPATOCELLULAR CANCER Principal Investigator & Institution: Afdhal, Nezam H.; Associate Professor of Medicine; Beth Israel Deaconess Medical Center St 1005 Boston, Ma 02215 Timing: Fiscal Year 2003; Project Start 25-SEP-2003; Project End 31-AUG-2005 Summary: (provided by applicant): Hepatitis C (HCV) is the commonest cause of chronic hepatitis, cirrhosis and hepatocellular carcinoma (HCC) in the United States. HCC occurs primarily in patients with advanced fibrosis and cirrhosis from HCV. Current screening techniques involve the use of serum alfafetoprotein and liver imaging with ultrasound performed in high risk patients on a 3 to 6 monthly basis. Early detection can improve outcomes with liver transplantation and perhaps non-surgical therapies. However screening is not very effective and many patients present with large tumors or multifocal HCC with a median survival of only 6 months. There is a definite clinical need for better non-invasive biomarkers for HCC which can lead to early detection and treatment. The specific aims of this exploratory R21 proposal are to utilize a proteomic approach to identify novel biomarkers for HCC and then evaluate these biomarkers in a cohort of patients with HCV at high risk for HCC. The initial step will be identification of a matching group of patients with a high risk of HCC and those who have developed HCC during the prospective COPILOT study. The COPILOT study provides a large cohort of patients with HCV and cirrhosis who are randomized to treatment with either low dose PEGylated interferon alfa 2b or colchicine and are followed for 4 years with rigorous clinical screening for HCC. The study is in year 2 and the incidence of HCC is approximately 5%. Serum from these patients prior to and after the development of HCC is stored and will be utilized for proteomic studies. Tissue from normal liver and HCC is available from these patients who have undergone liver transplant. A control disease serum bank from patients with HCC unrelated to HCV is also available at BIDMC. The serum and tissue will be examined by proteomics for identification of novel biomarkers using SELDI-TOF mass spectrometry. Careful clinical characterization and matching will assist in the bioinformatic approach necessary to identify candidate biomarkers. Novel proteins and peptide biomarkers will be sequenced and identified and an ELISA will be developed for any promising candidate biomarkers. The candidate biomarker ELISA will then be validated in the large HCV serum bank at BIDMC of patients with all stages of HCV and those in the COPILOT trial. These studies may lead to identification of more specific and sensitive biomarkers for HCC in HCV which can then be validated further in prospective clinical trials.

Project Title: REGULATION OF PULMONARY VASCULAR TONE DURING CIRRHOSIS Principal Investigator & Institution: Carter, Ethan P.; Associate Professor; Medicine; University of Colorado Hlth Sciences Ctr P.O. Box 6508, Grants and Contracts Aurora, Co 800450508 Timing: Fiscal Year 2001; Project Start 01-AUG-2001; Project End 31-JUL-2005 Summary: The cellular mechanisms governing the regulation of pulmonary vascular tone are complex and incompletely understood, particularly during pathphysiological

Cirrhosis
conditions. One such pathophysiological condition is hepatopulmonary syndrome. Hepatopulmonary syndrome is a clinical triad of advanced liver disease (usually cirrhosis), pulmonary gas exchange abnormalities (i.e. shunting) leading to severe systemic arterial hypoxemia, and widespread pulmonary vasodilations in the absence of intrinsic cardiopulmonary disease. This syndrome occurs in 15 - 30 percent of cirrhotic individuals and vastly complicates their treatment. Nitric oxide (NO) has been postulated to be central to the development of hepatopulmonary syndrome. An animal model of hepatopulmonary syndrome recently has been developed in rats that has proven useful for investigating to pathogenesis of hepatopulmonary syndrome. These animals have intrapulmonary shunting and hypoxemia. The mechanisms linking NO to the development of hepatopulmonary syndrome have not been defined. This proposal investigates the underlying mechanisms of hepatopulmonary syndrome using a comprehensive approach of in vivo and in vitro experimental strategies. We provide preliminary data demonstrating that in addition to elevated NO and eNOS, expression in lung of the vasocontrictor endothelin (ET-1) is decreased in cirrhotic rats. Evidence is also provided showing that vascular smooth muscle potassium channels are activated during cirrhosis. These are the first data ever, providing a mechanism for the pulmonary vasodilation and blunted hypoxic pressor response during cirrhosis. Additional data is shown demonstrating that during cirrhosis the stress response gene heme oxygenase-1 (HO-1) is significantly upregulated in lung and liver and decreased in kidney. HO-1 enzymatic activity liberates CO, a known vasodilator that can act via cGMP-dependent and -independent pathways. Therefore, it is possible that the tissuespecific regulation of the HO-1/CO axis contributes to the pulmonary vasodilation and renal vasoconstriction during cirrhosis. Finally, to investigate the role of NO in alterations to ET-1, potassium channels, and HO-1, cirrhotic rats were chronically treated with a NO inhibitor. This treatment resulted in a complete reversal of the cirrhotic associated changes to gene expression. Taken together, our data suggest that during cirrhosis, NO is central to the development of hepatopulmonary syndrome acting not only as a vasodilator but also as a regulator of gene expression of ET-1, potassium channels, and HO-1. We will test the hypotheses that: (1) chronic NO elevation during cirrhosis renders the pulmonary circulation unresponsive to hypoxia via direct vasodilatory actions and indirect modifications to gene expression; (2) factors released by the cirrhotic liver regulate pulmonary vascular tone; (3) HO-1 derived CO contributes to the pulmonary vasodilation during cirrhosis. This project will not only define the cellular basis for hepatopulmonary syndrome, but will also contribute to our understanding of how pulmonary vascular tone is controlled at the most basic level.

activation leading to alcohol-induced hepatic fibrosis. The overall goal of the research proposal is to identify the metabolic pathways of retinyl ester metabolism in hepatic stellate cells when they become activated to form myofibroblast-like cells. Hepatic stellate cells are the main reservoir of Vitamin A in liver. When animals are chronically exposed to alcohol or other hepatotoxins, the stellate cells become activated and transform into myofibroblast-like cells. These transformed cells are the sites of collagen synthesis and extracellular matrix formation in alcohol-induced hepatic fibrosis. One of the earliest events in stellate cell activation is the hydrolysis in retinyl palmitate esters. Multiple retinyl ester hydrolase and retinol dehydrogenase activities have been reported in human, rabbit and rat liver. However, the specific enzymes and genes involved in retinyl ester metabolism during the activation of hepatic stellate cells have not been identified. The specific aims are to develop methods to prepare stellate cells from rat, rabbit and/or human liver to identify the isoenzymes of retinyl ester hydrolases and retinol dehydrogenases present during stellate cell activation. The enzyme activation will be measured in cells. The catalytic and molecular properties of the retinyl palmitate hydrolases and retinol dehydrogenases will be characterized. The studies should provide new information on the role of retinoid metabolism in alcohol-induced liver disease. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen •
Project Title: RETROVIRAL ETIOLOGY OF PRIMARY BILIARY CIRRHOSIS Principal Investigator & Institution: Mason, Andrew L.; Associate Professor; Ochsner Clinic Foundation 1514 Jefferson Hwy New Orleans, La 70121 Timing: Fiscal Year 2001; Project Start 30-SEP-1997; Project End 31-DEC-2002 Summary: Primary biliary cirrhosis (PBC) is an idiopathic multisystem autoimmune disorder that primarily effects women. Patients with PBC have a pluriglandular syndrome resulting in cirrhosis and sicca syndrome, and a demonstrable autoimmune response to specific mitochondrial oxo-acid dehydrogenase E2 proteins. PBC patients are also prone to develop other autoimmune diseases such as Sjogren's syndrome, thyroiditis, and systemic lupus erythematosus. These autoimmune disorders have all been linked to rettroviral infection as by Western blot studies 30 to 35 percent of patients have indeterminate serum reactivity to HIV proteins and 85 to 05 percent have serum reactivity to human intracisternal A type particle (HIAP-I) which was isolated from salivary glands of patients with Sjogren's syndrome and also visualized by electron microscopy. Likewise, 15 percent of PBC patients have been reported to have false positive HIV ELISA reactivity and in preliminary studies, retrovirus particles have been observed by electron microscopy in the biliary epithelial cells of PBC patients but not controls. Using representational difference analysis, we have isolated and cloned novel retroviral nucleic acid sequences from the liver of a PBC patients. These clones have been used to screen a cDNA library made from bilary epithelium cells isolated from three transplant recipients with PBC. We have now identified more than ten qunique cDNA clones with sequence homology to HIV, SIV, HTLV-1, and IAP as well as the E2 mitochondrial autoantigens. To date, our RTPCR studies have revealed that all the RDA and 3 of 3 novel clones tested to data are not unique to PBC patients, suggesting that they may be derived from endogenous retroviruses. Also, we have conducted Western blot studies which reveal that approximately 74 percent of PBC patients sera have indeterminate reactivity to HIAP proteins and 35 percent of patients react to HIV p24 gag, compared to less than 5 percent of liver disease controls. This suggests that the putative PBC retrovirus shares antigenic determinants with HIV-I and HIAP-I but is a separate virus. In order to further characterize the agent associated with PBC, we plan to

identify specific retroviral proteins and nucleic sequences with the ultimate goal of investigating the role this virus plays in the eitology of PBC. Our specific aims are to (1) Clone full length PBC retrovirus from hepatic tissue and PBC cDNA libraries; (2) Isolate the PBC retrovirus in lymphoblastoid and hepatic cell lines by co-culture with infected hepatic tissue; (3) Assess the prevalence of retroviral infection in PBC patients and controls by nucleic acid hybridization techniques and western blot experiments of recombinant or purified viral proteins.

Project Title: ROLE OF CD40-CD40 LIGAND IN PRIMARY BILIARY CIRRHOSIS Principal Investigator & Institution: Mayo, Marlyn J.; Internal Medicine; University of Texas Sw Med Ctr/Dallas Dallas, Tx 753909105 Timing: Fiscal Year 2001; Project Start 15-MAY-2000; Project End 31-MAR-2003 Summary: (adapted from the application) Primary biliary cirrhosis is a chronic autoimmune liver disease characterized by inflammatory destruction of small and medium sized intrahepatic bile ducts, leading to cholestasis, then fibrosis, cirrhosis, and its complications. Although the etiology is unknown, T cells that surround the bile ductules are the likely mediators of bile duct destruction. Other cell types within the portal infiltrate, including macrophages and B cells, probably contribute to this autoimmune process. However, the manner in which these cells communicate and collaborate to cause bile duct lesions is not understood. The hypothesis of this proposed project is that T cells orchestrate the immune attack on cholangiocytes via signaling to other cells in the liver through CD40 ligand. Specifically, expression of CD40 ligand by activated T cells in the liver stimulates B cells to increase production of immunoglobulins; activates macrophages to produce IL-12, which leads to a shift of T helper cells to the Th1 phenotype and subsequent IL-2 and IFN-gamma production; and induces cholangiocytes to undergo apoptosis at an increased rate. This hypothesis will be tested by a correlative analysis of the level of expression of CD40 ligand in the liver of PBC patients with the potential consequences of CD40-CD40 ligand interaction; such as upregulation of immunoglobulin and cytokine production, and apoptosis of cholangiocytes. Expression of CD40 and CD40 ligand will be localized in the liver with immunohistochernistry. These patient-oriented studies will be supplemented by in vitro experiments designed to study CD40-ligand induced apoptosis in cholangiocytes. These studies will provide insight into the role of T cells in the pathogenesis of PBC and provide information useful in developing new treatment modalities.

Project Title: SMAD3 AS AN INHIBITOR OF ATHEROGENESIS Principal Investigator & Institution: Jain, Mukesh K.; Brigham and Women's Hospital 75 Francis Street Boston, Ma 02115 Timing: Fiscal Year 2001; Project Start 30-SEP-2001; Project End 31-JUL-2005 Summary: (provided by applicant): Recent studies have highlighted the importance of inflammation as a contributor to the pathogenesis of a number of chronic disease states such as rheumatoid arthritis, cirrhosis, glomerulosclerosis, inflammatory bowel disease and atherosclerosis. The infiltration of monocytes/macrophages is a characteristic feature seen in chronic inflammatory disease states. Indeed, experimental, clinical, and pathologic studies have established an essential role for the monocyte in the development of atherosclerotic lesions. As such, identification of mechanism(s) regulating monocyte/macrophage activation are of considerable interest. Transforming

growth factor beta (TGFb1) is a potent inhibitor of inflammation and immune cell activation. Definitive evidence for this role is derived from the fact that mice deficient in this factor succumb to a systemic inflammatory wasting syndrome. TGFb1 is expressed in human atherosclerotic lesions and its levels correlate inversely with the severity of clinical disease. The mechanism(s) by which TGFb1 is able to inhibit immune cells remains poorly understood. Recently, a family of proteins termed Smads have been identified as effectors of TGFb1 signaling. We hypothesized that members of this family may regulate TGFb1?s inhibitory effects on monocytes. Indeed, we found that one of these factors, termed Smad3, was able to recapitulate the inhibitory properties of TGFb1 with respect to monocyte/macrophage activation. These studies also suggest that inhibition occurs through a novel mechanism involving competition for rate-limiting quantities of critical cellular regulatory factors (co-activator competition). Thus, the goals of this study are to define the role of Smad3 in monocyte biology. First, we will dissect the molecular mechanisms governing Smad3 mediated inhibition in macrophages. Second, we will overexpress Smad3 in macrophages and assess effects on specific effector functions such as elaboration of cytokines, matrix degrading enzymes and lipid uptake. Third, we will assess the effect of Smad3 deficiency on the development of atherosclerosis in mice. Collectively, these studies should provide insight into the role of Smad3 in mononuclear cell biology both in vitro and in vivo. Furthermore, these results may serve as the basis of novel strategies to limit mononuclear cell activation and inflammation in a number of human disease states, including atherosclerosis.

Project Title: STRUCTURAL ANALYSIS OF THE HEPATITIS C CORE PROTEIN Principal Investigator & Institution: Allaire, Marc; Brookhaven Science AssocBrookhaven Lab Brookhaven National Lab Upton, Ny 11973 Timing: Fiscal Year 2003; Project Start 30-SEP-2003; Project End 31-JAN-2006 Summary: (provided by applicant): Hepatitis C virus (HCV) infection is recognized as a worldwide health problem affecting over 170 million individuals. In the United States, over 4 million peoples have been infected and 12,000 deaths yearly are due to hepatitis C. HCV is the most common reason for liver transplantation and accounts for one-third of hepatocellular carcinoma. Prevention of the HCV infection is impeded by the lack of protective vaccines and current therapies against HCV are unsatisfactory. There is clearly an urgent need for the development of new drugs. The molecular mechanisms of viral replication and viral assembly of HCV are poorly understood. It has been shown recently that nucleocapsid-like particles of HCV can be assembled from the HCV core protein that are identical to the HCV nucleocapsid from sera of infected patients. The aim of this proposal is to characterize the HCV core and capsid using macromolecular crystallography and to characterize the packaging signal on the viral RNA. The HCV core protein is the viral subunit of the HCV capsid. It appeared in the last few years that this protein is also very important for the pathogenesis of the disease by inducing cancer, cirrhosis and inflammation of the liver tissue. The resolution of the threedimensional structure of this protein and the capsid will not only help us to characterize the protein-protein interactions between the proteins subunits, the interaction between the subunits and the nucleic acid but also to resolve the surface of the capsid that interacts with several host factors responsible for different aspects of the pathogenesis of the disease. Altogether, the determination of the structure of the capsid will facilitate the development of research programs that aim to inhibit the assembly of the virus, a novel and very promising target for drug development.

Project Title: STUDIES OF THE NATURAL HISTORY OF HEPATITIS C IN LIVER Principal Investigator & Institution: Carithers, Robert L.; Director of Hepatology Section; Medicine; University of Washington Seattle, Wa 98195 Timing: Fiscal Year 2001; Project Start 30-SEP-1999; Project End 31-AUG-2003 Summary: Chronic hepatitis C virus infection has emerged as the most important form of viral hepatitis in the United States. Although the disease often remains indolent for many years, approximately 20 percent of patients with chronic hepatitis C progress to cirrhosis within 20 years. As a consequence, liver failure from chronic hepatitis C has become the leading indication for liver transplantation both in the United States and Europe. Despite remarkable progress in our understanding of many aspects of this disease, the mechanism of hepatocellular injury in patients with chronic hepatitis C is not well understood. Unfortunately, neither efficient cell culture systems nor animal models are available to study the pathogenesis of the liver disease. Given these limitations, we have systematically examined the evolution of liver injury in patients with recurrent hepatitis C after liver transplantation. By correlating the degree of injury to the transplanted organ with detailed analyses of viral replication we hope to provide insights into the pathogenesis of liver cell injury in these chronically infected patients. This proposal is designed to examine the hypothesis that differing patterns of mutation in the genomic sequence of HCV RNA have a profound influence on the severity of liver injury in patients with recurrent hepatitis C after liver transplantation. Our Specific Aim 1 is to prospectively determine the relationship between evolution of HCV quasispecies and hepatocellular injury in patients with recurrent hepatitis C. In Specific Aim 2 we plan to intensively investigate the clonal evolution of quasispecies and to determine the tissue origin of these viral strains both in patients with severe recurrent hepatitis C and in those with mild hepatocellular injury after liver transplantation. We plan to test the hypothesis that the primary site of quasispecies replication is critical to the development of hepatocellular injury. We propose that emergence of nonpathogenic strains of virus after liver transplantation result from continuous extrahepatic replication of HCV, whereas pathogenic strains of HCV originate from intrahepatic replication of the virus. In Specific Aim 3 we plan to assess in impact of HCV genotype, circulating levels of virus, and evolution of HCV quasispecies on the long term evolution of histologic injury in the transplanted liver. By carefully correlating the evolution of the virus with the degree of hepatocellular injury experienced by patients who develop recurrent hepatitis C after liver transplantation, we hope to provide insights into to the pathogenesis of this important liver disease. From these detailed analyses we also hope to isolate pathogenic strains of virus which can later be tested in cell culture systems. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen

cure for PBC. The most common symptoms associated with PBC are fatigue and pruritus. More than 90% of patients with PBC are women. The average age of diagnosis is about 50 years. Asymptomatic patients have a four-fold increase in mortality when compared to the U.S.A. population matched for age and the median survival from the onset of symptoms is 7.5 to 9 years. PBC is considered a model autoimmune disease; it is associated with hypergammaglobulinemia, autoantibodies, defects of immune regulation, and an increased incidence of other autoimmune conditions (thyroiditis, Sjogren's syndrome, scleroderma). The liver injury is characterized by a rich inflammatory infiltrate composed of CD4+ and CD8+ cells, cytokines, adhesion molecules and other immunologic mediators. The consequence of CNSDC is biliary cirrhosis and liver failure. The only treatment approved to treat PBC is ursodeoxycholic acid (UDCA), which appears to delay the time to liver transplantation but does not cure for the disease. Thus, the need for the provision of effective and safe treatments for PBC is clear. Patients with PBC may benefit from treatment with an appropriate immunosuppressive drug. Mycophenolate mofetil meets the criteria of a superior immunosuppressive agent. In this proposal we are going to explore immune mediators of PBC including T cells and adhesion molecules in patients with PBC and the effect of treatment with MMF in combination with UDCA on these factors in patients who are participants in a clinical trial.

Project Title: THE CNS AND CIRRHOSIS:PSYCHOBIOLOGICAL APPROACHES Principal Investigator & Institution: Stewart, Charmaine; Medicine; University of Pennsylvania 3451 Walnut Street Philadelphia, Pa 19104 Timing: Fiscal Year 2002; Project Start 01-SEP-2002; Project End 31-DEC-2002 Summary: (provided by applicant): Hepatic encephalopathy (HE) is one of the most common manifestations of decompensated cirrhosis. Approximately 70% of patients with cirrhosis also have subacute hepatic encephalopathy (SHE), as demonstrated on neuropsychological testing. The use of transjugular intrahepatic portosystemic shunts (TIPS), which acts as a side-to-side shunt, has become common to manage complications of cirrhosis. However, TIPS are associated with adverse effects, including worsening of existing HE or the precipitation of overt HE and liver failure. Liver transplantation has become the ideal management for patients who have decompensated liver disease. The principal hypothesis of this proposal is that changes of HE and SHE can be determined by neuropsychological testing and changes in cerebral blood flow (CBF). The Specific Aims are the following: (1) Determine the changes in cognitive function in patients with cirrhosis; (2) Identify changes in CBF and neurotransmitter activity, as assessed by central benzodiazepine receptor binding and serotonin transporter binding after TIPS insertion; (3) Identify changes in CBF and neurotransmitter activity, as assessed by central benzodiazepine receptor binding and serotonin transporter binding after liver transplantation; and (4) Correlate the neuropsychological changes with cognitive function and central benzodiazepine receptor binding and serotonin transporter binding. These Specific Aims will be pursued in 60 subjects: group I will be 20 cirrhotics who will undergo TIPS; group II will be 20 cirrhotic patients who are scheduled to undergo liver transplantation; and group III will be 20 age and sex matched cirrhotic controls. All groups will be studied with a battery of neuropsychological tests and stimulated CBF, using 1502 labeled water, while half of groups I and II will be tested with 11C flumazenil PET or (11C)(+)McN5652 positron emission tomography (PET), in order to determine central benzodiazepine receptor binding and serotonin transporter binding, respectively, before and one month after undergoing TIPS or liver

transplantation. The control group will be studied with 11C flumazenil PET or (11C)(+)McN5652 PET at baseline and 1 month, thereafter. In aggregate, these studies will provide a platform to elucidate cognitive and biological mechanisms underlying hepatic encephalopathy with the ultimate goal of enhancing diagnosis and management. Additionally, the proposed studies will be guided by a team of mentors and sponsors and supplemented by a didactic curriculum, all to lay the foundation for eventual independent clinical investigator status.

Project Title: THE ROLE OF LEPTIN IN LIVER FIBROGENESIS Principal Investigator & Institution: Anania, Frank A.; Assistant Professor; Medicine; University of Maryland Balt Prof School Baltimore, Md 21201 Timing: Fiscal Year 2003; Project Start 01-JUN-2003; Project End 31-MAR-2007 Summary: (provided by applicant): Non-alcoholic steatohepatitis or non-alcoholic fatty liver (NAFL) is a growing clinical problem that may account for a newly recognized etiology for cryptogenic cirrhosis. Leptin, a 16-kilodalton protein resulting from the transcription of the obese gene, is a hormone associated with weight and satiety control. NAFL, along with obesity, type II diabetes mellitus, and hyperlipidemia, are conditions characterized by high circulating concentrations of the hormone leptin. The overall goal of this proposal is to demonstrate the biological consequences of leptin as a novel mediator of liver fibrosis, the precursor to cirrhosis. Preliminary data indicate leptin has profibrogenic activity in the principal collagen producing cells of the liver, hepatic stellate cells (HSCs). In vivo data indicate that leptin is also required for liver fibrosis induced by carbon tetrachloride (CCl4) in lean, but not obese, mice. The preliminary data and the current proposal meet the long-term objectives of this laboratory: to understand basic mechanisms underlying chronic liver fibrosis. In this proposal, it is hypothesized that leptin is a profibrogenic cytokine in activated hepatic stellate cells and increases (2(I) collagen expression by phosphorylated signal transduction and activator of transcription (pSTAT) enhancing AP-1 binding to the alpha2(I) collagen promoter. Three aims are outlined to test this hypothesis. First to (a) further characterize leptin as a novel profibrogenic cytokine by examining genes responsible for increased extracellular matrix (ECM) production in fibrotic liver; and (b) to elucidate the specific signal transduction pathway(s) responsible for the effect of leptin on (2(I) collagen expression in HSCs. Second to (a) characterize leptin-associated alpha2(I) collagen mRNA stabilization; to (b) identify specific cis-acting elements along the human alpha2(I) collagen promoter affected by leptin signaling that are responsible for increased collagen gene expression by employing deletion mutant and site-directed mutagenesis; and (c) to identify, by DNase I protection analysis and electrophoretic mobility shift assay, specific transcription factors associated with leptin altered collagen gene expression. Third, to exploit rodent animal models of obesity, and their lean littermates, to determine the mechanisms by which leptin may be required for liver fibrosis in wildtype mice exposed to CC14 but not in identically treated db/db or ob/ob mice; and whether leptin is required in a common bile duct ligation (CBDL) injury model using fa/fa, or Zucker Diabetic Fatty (ZDF) rats and their lean littermates.

71
Timing: Fiscal Year 2001; Project Start 01-APR-1993; Project End 31-MAR-2004 Summary: The major thrust of this randomized, double-blinded clinical trial is to determine whether treatment of patients with Primary Biliary Cirrhosis (PBC) with Ursodiol (Ursodeoxycholic Acid-UDCA) plus methotrexate (MTX) is more effective than treatment with UDCA alone. PBC is a chronic cholestatic liver disease, predominantly of women, in which interlobular and septal bile ducts undergo inflammation and destruction. Once initiated, the disease persists and progresses at varying rates. Neither the initiating nor perpetuating mechanisms are well understood. Current concepts of pathogenesis include (1) destruction of bile ducts is maintained and perhaps initiated by autoimmune mechanisms; (2) hydrophobic bile acids which accumulate in serum and liver cause functional and cytotoxic liver injury; (3) cytokines and lymphokines released at sites of inflammation may contribute to cell damage and fibrosis. A considerable body of evidence indicates that UDCA when fed orally leads to improvement in liver tests, in pruritus and in liver histology. There exist differences in opinion as to whether development of complications of liver disease, liver transplantation or transplant-free survival is affected. UDCA a relatively non-toxic bile acid, when administered orally, alters the composition of the bile acid pool in factor of its enrichment with UDCA and appears to protect against the cytotoxic effects of endogenous bile acids that accumulate as a result of bile duct destruction. MTX is being shown to improve liver tests, symptoms and liver histology in a small number of precirrhotic patients with PBC. The mechanism of action is unknown but felt to be related to antiinflammatoryimmunosuppressive effects of MTX. The current trial explores whether MTX improves the therapeutic effects of UDCA in PBC. Patients with PBC whose serum bilirubin is less than 3 mg percent, who have been on UDCA for at least 6 months, and who satisfy a series of inclusion and exclusion criteria are stratified into 2 groups on the basis of liver histologic stage (Ludwig classification), i.e. early (Stages I or II) versus late (Stages III or IV). They are then randomized to receive either methotrexate or its placebo as a second drug while continuing to receive UDCA. The relative value of the two treatment arms is assessed by comparing their effects on symptoms, results of laboratory tests, development of complications of liver disease, histologic changes in liver, liver transplantation, and on transplant-free survival. The safety of each therapeutic regimen is also being determined. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen •

FOR
Principal Investigator & Institution: Fox, Ira J.; Professor; Surgery; University of Nebraska Medical Center Omaha, Ne 681987835 Timing: Fiscal Year 2003; Project Start 01-JUL-2003; Project End 31-DEC-2006 Summary: (provided by applicant): The vast majority of patients awaiting organ transplantation have end-stage chronic liver disease secondary to cirrhosis. Hepatocyte transplantation has several important advantages over organ transplantation and was recently shown to prolong the survival and improve the physiologic abnormalities associated with cirrhosis and end-stage liver disease in rodents. The number of human livers available for hepatocyte isolation and later transplantation, however, is limited. One possible solution to the human donor availability issue is transplantation of hepatocytes from pigs. Two major concerns regarding the use of porcine hepatocytes in man relate to the degree to which xenogeneic hepatocytes can restore normal liver physiology to patients with liver dysfunction and the immunological response to liver cells or their products. Preliminary studies indicate that immunosuppression may not be

needed to improve the survival or function of allogeneic rat or pig hepatocytes transplanted in cirrhotic rats. However, specific antibody and cellular immune responses to pig hepatocytes vary by species and the specific physiologic compatibility and function of pig liver proteins in man is unknown. We now propose to extend our observations in a primate model that will serve as a prelude to clinical application. The aims of this proposal are: 1) To test the degree to which porcine hepatocyte transplantation can improve liver function in cirrhotic non-human primates; 2) To examine whether pig hepatocytes are susceptible to rejection mediated by anti-swine antibodies and test whether the primate immune response to porcine hepatocytes is significantly different in cirrhotic versus non-cirrhotic recipients; and 3) To determine whether porcine hepatocyte transplantation leads to systemic complications that include a) immune complex formation, b) activation of the coagulation/complement system and c) immune sensitization that may preclude later allotransplantation.

CHAPTER 2. NUTRITION AND CIRRHOSIS Overview In this chapter, we will show you how to find studies dedicated specifically to nutrition and cirrhosis.
Finding Nutrition Studies on Cirrhosis 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 “cirrhosis” (or synonyms) into the search box, and click “Go.” To narrow the search, you can also select the “Title” field.

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 3. ALTERNATIVE MEDICINE AND CIRRHOSIS Overview In this chapter, we will begin by introducing you to official information sources on complementary and alternative medicine (CAM) relating to cirrhosis. At the conclusion of this chapter, we will provide additional sources.
The Combined Health Information Database The Combined Health Information Database (CHID) is a bibliographic database produced by health-related agencies of the U.S. federal government (mostly from the National Institutes of Health) that can offer concise information for a targeted search. The CHID database is updated four times a year at the end of January, April, July, and October. Check the titles, summaries, and availability of CAM-related information by using the “Simple Search” option at the following Web site: http://chid.nih.gov/simple/simple.html. In the drop box at the top, select “Complementary and Alternative Medicine.” Then type “cirrhosis” (or synonyms) in the second search box. We recommend that you select 100 “documents per page” and to check the “whole records” options. The following was extracted using this technique: •
Milk Thistle: Effects on Liver Disease and Cirrhosis and Clinical Adverse Effects Source: Gaithersburg, MD: National Center for Complementary and Alternative Medicine. 2000. 12 p. Contact: Available from National Center for Complementary and Alternative Medicine Clearinghouse. P.O. Box 7923, Gaithersburg, MD 20898. (888) 644-6226; INTERNATIONAL PHONE: (301) 519-3153; TTY: (866) 464-3615; FAX: (866) 464-3616; EMAIL:
[email protected]. PRICE: Free. Publication Number: D029. Summary: This evidence report details a systematic review summarizing clinical studies of milk thistle in humans. The report addresses two areas: (1) the effects of milk thistle on liver disease of alcohol, viral, toxin, cholestatic, and primary malignancy etiologies, and (2) the clinical adverse effects associated with milk thistle ingestion or contact. It addresses ten questions regarding whether milk thistle supplements (when compared with no supplement, placebo, other oral supplements, or drugs): (1) alter the physiologic
134 Cirrhosis
markers of liver function, or (2) reduce mortality or morbidity, or improve the quality of life in adults with alcohol-related, toxin-induced, or drug-induced liver disease, viral hepatitis, cholestasis, or primary hepatic malignancy. One question addresses the constituents of commonly available milk thistle preparations, and three questions address the common and uncommon symptomatic adverse effects of milk thistle. The report explains the methodology, followed by a summary of its findings, including mechanisms of action, preparations of milk thistle, benefit of milk thistle for liver disease, and adverse effects. It summarizes conclusions and discusses areas for future research. The addendum includes evidence-based practice centers, topics, available evidence reports, and contact information.
National Center for Complementary and Alternative Medicine The National Center for Complementary and Alternative Medicine (NCCAM) of the National Institutes of Health (http://nccam.nih.gov/) has created a link to the National Library of Medicine’s databases to facilitate research for articles that specifically relate to cirrhosis and complementary medicine. To search the database, go to the following Web site: http://www.nlm.nih.gov/nccam/camonpubmed.html. Select “CAM on PubMed.” Enter “cirrhosis” (or synonyms) into the search box. Click “Go.” The following references provide information on particular aspects of complementary and alternative medicine that are related to cirrhosis: •

Recent Trials on Cirrhosis The following is a list of recent trials dedicated to cirrhosis.8 Further information on a trial is available at the Web site indicated. •
Gabapentin to treat itch in patients with liver disease Condition(s): Liver Disease; Cholestasis; Cirrhosis; Pruritus; Itching Study Status: This study is currently recruiting patients. Sponsor(s): National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) Purpose - Excerpt: In this study, the effect of the medication gabapentin to treat itching secondary to liver disease is being studied. There are some funds to cover travel expenses for patients who are not from New York. Gabapentin is approved to treat seizures in human beings. In this study, patients with liver disease who meet inclusion criteria are admitted to the research hospital of the New York Presbyterian Hospital to record scratching behavior by the use of a machine designed for that purpose. Blood work will be obtained. After completion of recording, patients are assigned by chance to receive active medication or placebo (a capsule that does not contain active medication). The patients will come to the outpatient office of the research hospital 2 weeks into the study for an interview and blood work. After 4 weeks, patients are readmitted to the hospital to record scratching behavior. After data are collected, the code is broken, if patient had been on inactive drug, active drug will be supplied as per protocol for 4 weeks. Blood work will be obtained. If patient had been randomized to active medication, the study will provide one week supply of drug. After that, the referring physician, with whom the study was previously discussed, could prescribe the medication as it is available. Phase(s): Phase III

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. 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
Clinical Trials 155
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.

Role of nitric oxide in cirrhosis: relationship with systemic hemodynamics, renal function, vasoactive systems and endotoxemia Condition(s): Cirrhosis; Liver Cirrhosis Study Status: This study is currently recruiting patients. Sponsor(s): National Center for Research Resources (NCRR) Purpose - Excerpt: This study is to determine whether a compound, nitric oxide, made within the body, is the factor responsible for the changes in blood pressure and renal (kidney) functions that may occur during the course of cirrhosis. Patients with cirrhosis (liver scarring which causes poor liver function) will be eligible to participate. A group of healthy subjects will also be studied to compare the effects of the treatment to patients with cirrhosis and to confirm safety. A total number of 30 patients with cirrhosis and 10 healthy subjects will be enrolled in the study.

Thymosin Plus PEG-Interferon in Hepatitis C Patients with Cirrhosis Who Did Not Respond to Interferon or Interferon Plus Ribavirin Condition(s): Hepatitis C; Hepatitis C, Chronic Study Status: This study is currently recruiting patients. Sponsor(s): SciClone Pharmaceuticals Purpose - Excerpt: Chronic hepatitis C infection is one of the leading causes of chronic liver disease in the United States. Approximately one-third of patients with hepatitis C infection develop cirrhosis of the liver, which can lead to liver failure or liver cancer. The current treatment for hepatitis C infection in previously untreated patients is successful in only about half of patients. There is no established therapy for non-responders. This is a randomized, double-blinded, multicenter trial to determine the effectiveness of thymosin alpha 1 (thymalfasin) 1.6 mg twice weekly plus PEGinterferon alfa-2a 180
156 Cirrhosis
ug/wk compared to placebo plus PEGinterferon alfa-2a in adults with chronic hepatitis C with early cirrhosis or progression to cirrhosis who are non-responders to previous treatment with interferon or interferon plus ribavirin. The definition of non-response requires a positive HCV RNA test at the end of a course of at least 12 weeks of therapy. Patients will receive treatment for 12 months, and will be followed-up for a further 6 months after the end of therapy Phase(s): Phase III Study Type: Interventional Contact(s): see Web site below Web Site: http://clinicaltrials.gov/ct/show/NCT00039962 •

Long Term Interferon for Patients Who Did Not Clear Hepatitis C Virus with Standard Treatment Condition(s): Chronic Hepatitis C; Cirrhosis, Liver; Fibrosis, Liver; Hepatic Cirrhosis Study Status: This study is no longer recruiting patients. Sponsor(s): National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK); National Institute of Allergy and Infectious Diseases (NIAID); National Center on Minority Health and Health Disparities (NCMHD); National Cancer Institute (NCI); Hoffmann-La Roche Purpose - Excerpt: The HALT-C Trial is a National Institute of Diabetes and Digestive and Kidney Diseases sponsored, randomized clinical trial of long-term use of Peginterferon alfa-2a (pegylated interferon) in patients who failed to respond to prior interferon treatment. All patients who enter the trial will be treated for 6 months with Peginterferon alfa-2a and Ribavirin. Patients who respond to this 6 month treatment will continue to be treated for an additional 6 months. Patients who do not respond to this treatment will be eligible for the long-term maintenance phase of this study where patients will be randomly selected to be treated with Peginterferon alfa-2a or to discontinue treatment for 3.5 years. Patients in both arms of this study will be followed closely with quarterly study visits. The combination of peginterferon plus ribavirin has recently been approved by the FDA for treatment of chronic HCV. Patients who remain HCV-RNA positive after being treated for at least 6 months with peginterferon and ribavirin outside of this study may be eligible to directly enter the randomized portion of the HALT-C Trial. The HALT-C study is designed to determine if continuing interferon long-term over several years will suppress Hepatitis C virus, prevent progression to cirrhosis, prevent liver cancer and reduce the need for liver transplantation.

Prevention of Esophageal Varices by Beta-Adrenergic Blockers Condition(s): Esophageal and Gastric Varices; Liver Cirrhosis; Portal Hypertension Study Status: This study is completed. Sponsor(s): National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) Purpose - Excerpt: The purpose of this study is to learn whether timolol is useful in preventing or delaying the appearance of gastroesophageal varices, a complication that may develop in the future as a consequence of liver disease. Cirrhosis causes an increased resistance of blood flowing through the liver. This leads to an increased pressure in the portal vein (the vein that takes blood to your liver). High portal pressure is responsible for the appearance of complications of chronic liver disease such as varices and variceal bleeding (bleeding from veins in your esophagus). Timolol belongs to a group of medications called beta-blockers. Beta-blockers decrease high portal pressure and previous studies have shown that beta-blocker pills are useful in preventing bleeding from varices in patients who already have varices. A more desirable effect would be if these pills could prevent not only bleeding from varices but the appearance of varices (and therefore of bleeding).

CHAPTER 6. PATENTS ON CIRRHOSIS 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 “cirrhosis” (or a synonym) in their titles. To accurately reflect the results that you might find while conducting research on cirrhosis, we have not necessarily excluded non-medical patents in this bibliography.
Patents on Cirrhosis By performing a patent search focusing on cirrhosis, 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

Cardiovascular uses of cannabinoid compounds Inventor(s): Ellis; Earl F. (Midlothian, VA), Kunos; George (Bethesda, MD), Sanyal; Aron (Mechanicsville, VA), Varga; Karoly (Richmond, VA), Wagner; Jens (Richmond, VA) Assignee(s): Virginia Commonwealth University (Richmond, VA) Patent Number: 5,939,429 Date filed: September 29, 1998 Abstract: Hemorrhagic shock and in other conditions associated with excessive vasoconstriction, such as hypertension, peripheral vascular disease, cirrhosis of the liver, or certain forms of angina pectoris can be treated by using agonists of CB1 receptors as well as other cannabinoid receptors. In addition, it has been determined that in septic shock and cirrhosis of the liver when hypotension is due to activation of macrophages by bacterial endotoxin, the use of a drug that selectively blocks CB1 receptors or other cannabinoid receptors may be of therapeutic value by preventing or attenuating the endotoxin-induced hypotension. Excerpt(s): The invention relates to the cardiovascular effects of cannabinoid compounds, i.e. naturally occurring as well as synthetic substances that bind with high affinity to cannabinoid receptors in the brain and in peripheral tissues of mammals, including man. Naturally occurring cannabinoids may be divided into two categories, plant-derived and endogenous. Plant-derived cannabinoids are known to elicit dramatic psychobehavioral effects, exemplified by the well-known.DELTA.sup.9 tetrahydrocannabinol (THC), the psychotropic principle in marijuana. They are also known to have complex cardiovascular effects, a prominent component of which is hypotension (Vollmer et al. J. Pharm. Pharmacol. 1974, 26:186-198) Endogenous cannabinoids (endocannabinoids) are a class of lipid-like molecules that share receptor binding sites with plant-derived cannabinoids and mimic many of their neurobehavioral effects (Mechoulam et al. Adv. Exp. Bio. Med. 1996, 402:95-101.) Two endocannabinoids have been characterized in some detail: arachidonyl ethanolamide (anandamide) (Devane et al. Science 1992, 258:1946-1949; Felder et al. Proc. Natl. Acad. Sci. USA. 1993, 90:7656-7660) and 2-arachidonyl glyceride (2-AG) (Mechoulam et al. Biochem. Pharmacol 1995, 50:83-90). Like plant-derived cannabinoids, both anandamine and 2-AG are capable of eliciting hypotension (Varga et al. FASEB J. 1998, 12:1035-1044; Varga et al. Eur. J. Pharmacol. 1995, 278:279-283; Stein et al. Br. J. Pharmacol. 1996, 119:107-114; Varga et al. Hypertension 1996, 28:682-688; Lake et al. Hypertension 1997, 29:1204-1210; Calignano et al. Eur. J. Pharmacol. 1997, 337: R1-R2). In addition, various cannabinoid compounds have been produced synthetically. Cannabanoids exert their effects by binding to specific receptors located in the cell membrane. To date, two types of highaffinity cannabinoid receptors have been identified by molecular cloning: 1) CB1 receptors, present mostly in brain (Devane et al. Mol. Pharmacol. 1988, 34:605-613; Matsuda et al. Nature 1990, 346:561-564) but also in some peripheral tissues (Shire et al. J. Biol. Chem. 1995, 270:3726-3731; Ishac et al. Br. J. Pharmacol. 1996, 118:2023-2028), and 2) CB2 receptors, present on macrophages in the spleen (Munro et al. Nature 1993, 365:61-65). Web site: http://www.delphion.com/details?pn=US05939429__

Composition for the control of wound scar production Inventor(s): Lee; Raphael C. (Chicago, IL) Assignee(s): Massachusetts Institute of Technology (Cambridge, MA) Patent Number: 5,902,609 Date filed: October 25, 1996 Abstract: This invention pertains to a composition for controlling wound scar production containing a calcium antagonist and a protein synthesis inhibitor. The method can be used to minimize wound scars, such as hypertrophic wound healing disorders keloids and burn scar contractures in humans or other mammals, particularly those individually prone to excesssive scarring Calcium antagonist treatment can also be used to control diseases associated with excessive scarring. such as cirrhosis of the liver, constructive pericarditis Dupuytren's disease of the hand, plantar fibrosis of the foot, and various other fibromatoses. Excerpt(s): The ability to heal by forming scars is essential for mammalian systems to survive wounding after injury. Normally, wound healing is a continuous process extending over a one-to-two-year period The process can be conceptually divided into three fundamentally distinct stages. The first stage is an intensely degradative phase called the inflammatory stage It occurs immediately after injury and provides a leans to remove the damaged tissues and foreign matter from the wound. Two-to-three days later, as fibroblasts from the surrounding tissue move into the wound, the repairing process enters its second stage, the proliferation and matrix synthesis stage. The fibroblasts in the wound proliferate and actively produce macromolecular such as collagen and proteoglycans, which are secreted into the extracellular matrix. The newlysynthesized collagen fibrils are cross-linked by lysyl oxidase and provide structural integrity to the wound. During this stage, fibroblasts also contract the intact collagen in order to reduce the surface area of the wound. This second stage lasts about three weeks. In the final, remodeling stage, the previous randomly-organized collagen fibril is aligned in the direction of mechanical tension and becomes more organized so that the mechanical strength of the wound area can be increased. The repair process is accomplished when the chemical and physical barrier functions of the skin are restored. Normal wound healing follows a well-regulated course. However, imbalances may cause abnormal scars to form. For example if the biosynthetic phase continues longer than necessary or degradation of collagen decreases, hypertrophic scars may form. These scars cause problems ranging from aesthetic deformity to severe limitation of motion. Hypertrophic scars more frequently occur among children and adolescents, suggesting that growth factors may influence the development of this type of scar. Hypertrophic scars are especially common in patients who have burns or wounds that heal by secondary intention. Another type of excess scar is the keloid. In this disorder, the cells appear to lace sensitivity to normal feedback signals. They are larger than hypertrophic scars and grow in an unregulated way, tending to invade normal tissue surrounding the wound. They rarely disappear spontaneously and often recur after surgical excision. The management of these scars remains a major unsolved clinical problem.

Diagnostic kit Inventor(s): Hirose; Masao (Aichi, JP), Komai; Koichiro (Hyogo, JP), Mori; Masaki (Aichi, JP), Saito; Koichi (Hyogo, JP) Assignee(s): Sumitomo Chemical Company, Limited (Osaka, JP) Patent Number: 5,985,542 Date filed: May 20, 1997 Abstract: The present invention provides:a diagnostic kit for liver diseases such as hepatitis C and alcoholic cirrhosis to be applied to a human serum sample, which contains an antibody capable of recognizing a human cytochrome P450; anda process for determining the concentration of a cytochrome P450 in a human serum for diagnosis of hepatitis C and alcoholic cirrhosis. Excerpt(s): The present invention relates to a diagnostic kit for hepatitis C and alcoholic cirrhosis. Activities of enzymes such as GOT (glutamic-oxaloacetic transaminase), GPT (glutamic-pyruvic transaminase),.gamma.-GTP (.gamma.-glutamyl transpeptidase) and the like have been measured as biological markers of human liver complaints with certain kits for diagnosis. These enzyme activities, however, were not always satisfactory to specify a disease, since they did not distinguish liver diseases, such as viral hepatitides hepatitis A, hepatitis B, non-A non-B hepatitise, alcohol-induced hepatic injury and drug-induced hepatic injury.

Galenic preparation for prevention and treatment of hepatocarcinoma Inventor(s): Lee; Jung Sik (Seoul, KR) Assignee(s): Sam Chun Dang Pharm Co., Ltd. (Seoul, KR) Patent Number: 6,074,648 Date filed: August 7, 1998 Excerpt(s): The present invention relates to a galenic preparation for prevention and treatment of hepatocarcinoma. More specifically, the present invention relates to a galenic preparation which comprises an injectable composition having a good preventive and therapeutic effect particularly against viral hepatitis B and containing 4 kinds of main natural drugs, i.e., Hedyotidis herba, Curcumae longae rhizoma, Polygoni cuspidati radix and Sophorae tonlkinesis radix; and an oral composition having a preventive and therapeutic effect against fatty liver and hepatic cirrhosis and containing 10 kinds of natural drugs, i.e., Hedyotidis herba, Paridis rhizoma, Polygoni cuspidati radix, Sophorae tonkinesis radix, Gentianae scabrae radix, Rhei rhizoma, Forsythiae fructus, Paeoniae radix rubra, Curcumae longae rhizoma and Acori graminei rhizoma, and which can effectively prevent the development of hepatic diseases including hepatitis, fatty liver and hepatic cirrhosis into hepatocarcinoma and treat hepatocarcinoma by combined administration of two kinds of the compositions. The etiology of hepatocarcinoma have not yet been clearly established. However, hepatocarcinoma is statistically characterized by the fact that the incidence rate is higher in men, rather than in women, who are in their forties to sixties, and it may be accompanied by hepatic cirrhosis in approximately 80% and by hepatitis C in 10%. Such characteristics are consistent with the fact that the areas in which hepatocarcinoma is predominant, such as Far east and East South Asia including Korea, Southern Europe, Africa, etc. also has a high frequency of hepatitis B virus carrier. In these areas, it may be found that hepatocarcinoma attacks in the group of one family. Further, chronic hepatic disorders including hepatic cirrhosis, chronic hepatitis, etc. have a relatively high tendency to develop hepatocarcinoma, regardless of hepatitis B and C. In addition, it has been known that the frequency to develop hepatocarcinoma from chronic hepatitis and hepatic cirrhosis may be increased 6-8 times by alcohol intake or smoking. In many cases, hepatocarcinoma shows its unique symptoms only after it is considerably aggravated. Hepatocarcinoma shows various symptoms which include, generalized ones, such as systemic malais, anorexia, etc., hypertrophy of liver at right epigastrium and formation of mass in liver, and further a general deteriorated symptoms of hepatic cirrhosis such as ascites, jaundice, spleen hypertrophy, etc. Web site: http://www.delphion.com/details?pn=US06074648__

Human cardiac/brain tolloid-like protein Inventor(s): Arleth; Anthony J (Hatfield, PA), Elshourbagy; Nabil A. (West Chester, PA), Li; Xiaotong (Devon, PA), Willette; Robert N (Pottstown, PA) Assignee(s): SmithKline Beecham Corporation (Philadelphia, PA) Patent Number: 6,008,017 Date filed: December 16, 1997 Abstract: HC/BTLP polypeptides and polynucleotides and methods for producing such polypeptides by recombinant techniques are disclosed. Also disclosed are methods for utilizing hC/BTLP polypeptides and polynucleotides in the design of protocols for the treatment of restenosis, atherosclerosis, congestive heart failure (CHF), chronic obstructive pulmonary disease (COPD), benign prostatic hypertrophy (BPH), nephritis, fibrosis, glomerulonephritis, gliosis, cirrhosis and anomalies of wound healing, such as keloids among others, and diagnostic assays for such conditions. Excerpt(s): This invention relates to newly identified polynucleotides, polypeptides encoded by them and to the use of such polynucleotides and polypeptides, and to their production. More particularly, the polynucleotides and polypeptides of the present invention relate to the astacin protein family, hereinafter referred to as human cardiac/brain tolloid-like protein (hC/BTLP). The invention also relates to inhibiting or activating the action of such polynucleotides and polypeptides. The hC/BTLP gene appears to possess all of the important protein domains present in the bone morphogenetic protein (BMP)-1/procollagen C-proteinase (PCP) protein. Members of the astacin family of metalloproteinases, such as BMP-1, have previously been linked to cell differentiation and pattern formation during development through a proposed role in the activation of latent growth factors of the TGF-.beta. superfamily. In addition, recent findings indicate that BMP-1 is identical to PCP, which is a metalloproteinase involved in the synthesis of matrix collagen. This observation suggests that a functional link may exist between astacin metalloproteinases, growth factors and cell differentiation and pattern formation during development, as well as fibrotic processes characterized by the accumulation of matrix collagen. Nucleotide and amino acid sequence homologues suggest that hC/BTLP, like BMP-1, possesses PCP activity. PCP activity is one of the essential enzymatic steps required for the extracellular production of insoluble collagen fibrils from soluble procollagen. However, mouse mammalian tolloid-like protein is the most closely related homologue of hC/BTIP. Mouse mammalian tolloid-like protein and BMP-1 are distinct gene products with differential tissue distribution. Based on cross-species comparisons, the regulation and distribution of hC/BTIP would be expected to be distinct from BMP-1. Indeed, mouse mammalian tolloid-like protein exhibits a unique tissue distribution when compared to BMP-1. Thus, the selective inhibition of matrix collagen accumulation is important in highly localized fibrotic disorders, e.g., gliosis associated with neurotrauma and ventricular fibrosis associated with congestive heart failure. This indicates that the astacin protein family has an established, proven history as therapeutic targets. Web site: http://www.delphion.com/details?pn=US06008017__

Identification of a novel retrovirus associated with primary biliary cirrhosis and autoimmune disorders Inventor(s): Mason; Andrew L. (New Orleans, LA), Neuberger; James (Worcester, GB), Xu; Lizhe (Metairie, LA) Assignee(s): Alton Ochsner Medical Foundation (New Orleans, LA) Patent Number: 6,468,737 Date filed: June 1, 2000 Abstract: The present invention relates, first, to the discovery, identification, and characterization of novel nucleic acid molecules, that are associated with PBC, Sjogren's syndrome, scleroderma, SLE, autoimmune thyroiditis and various other connective tissue disorders. The novel nucleotide sequences of the present invention are retroviral in origin and are indicative of a PBC retrovirus which bears a strong correlation with PBC. The present invention is based, in part, on the Applicant's data which is the first evidence to suggest that PBC patient's tissue may harbor a transmissible agent. The association of a retroviral infectious agent with PBC was first demonstrated by Applicants in vitro by co-culture of periportal lymph nodes derived from patients at time of transplantation and healthy biliary epithelium cells. The Applicant's discoveries as described herein, report the characterization of PBC-associated infectious agent as retroviral as demonstrated by electron microscopy and immunoblot reactivity. In addition, Applicants have characterized novel nucleotide sequences which are associated with the PBC-associated retrovirus. Excerpt(s): The present invention relates first, to the identification of a novel human retrovirus and the novel nucleotide sequences encoding a retroviral long terminal repeat and reverse transcriptase nucleotides associated with the existence of primary biliary cirrhosis (PBC), and other immune disorders such as Sjogren's syndrome, scleroderma, systemic lupus erythematosus (SLE), autoimmune thyroiditis and various other connective tissue disorders, in addition to lymphoma and breast cancer. The present invention further relates to methods for using the PBC retroviral nucleotides for the detection of PBC, Sjogren's syndrome, scleroderma, SLE, autoimmune thyroiditis and various other connective tissue disorders in patient samples. The present invention also relates to methods for using and targeting the PBC retroviral long terminal repeat and reverse transcriptase nucleotides in gene therapy protocols for the treatment of PBC, Sjogren's syndrome, scleroderma, SLE, autoimmune thyroiditis and various other connective tissue disorders in patients in need of such treatment. The present invention also relates to methods of treating or inhibiting PBC retroviral infection with antiviral agents, such as cytokines, inhibitors of reverse transcriptase, inhibitors of viral capping, and inhibitors of viral protease. The present invention further relates to diagnostic protocols and kits for the detection of PBC, Sjogren's syndrome, scleroderma, SLE, autoimmune thyroiditis and various other connective tissue disorders in tissue samples. Primary biliary cirrhosis (PBC) is a progressive pluriglandular disease affecting the liver, pancreas, salivary and lachrymal glands (Neuberger, 1997, Lancet 850:875-79; Epstein et al., 1980, Lancet 1:1166-68). The hepatic disease is characterized by a florid bile duct lesion with lymphocytic infiltration and granulomatous destruction of 30 to 80.mu.m sized interlobular bile ducts (Rubin et al., 1965, Am. J. Pathol. 46:387-407). There is no curative therapy, apart from liver transplantation, and patients usually develop cirrhosis (Neuberger et al., 1997, Lancet 250:875-879). It is estimated to account for approximately 2% of patients dying from cirrhosis in Europe and 10% of patients that requiring orthotopic liver transplantation in North America (Neuberger et al., 1997, Lancet 250:875-879). The autoimmune phenomena associated with PBC have been well
170 Cirrhosis
characterized. Over 95% of PBC patients have antibodies that bind and inhibit the dihydrolipoamide acetyltransferase enzymatic function of the E2 subunit of the pyruvate dehydrogenase complex (PDC) (Gershwin et al., 1992, Molecular biology of the 2-oxo-acid dehydrogenase complexes and anti-microbial antibodies. Philadelphia W. B. Saunders) These AMA have a higher affinity to the dehydrogenase E2 enzymes of mammals as compared to invertebrates and react to the E2 sub-units of other highly conserved inner membrane mitochondrial proteins of the oxoglutarate dehydrogenase complex, and branched chain 2-oxoacid dehydrogenase complex, and also the E1.alpha. and E1.beta. sub-units of PDC. For patients with liver disease, reactivity to the E2 mitochondrial enzymes is specific to PBC but these AMA have been observed in individuals with Sjogren's syndrome and SLE as well (Van-de-Water et al., 1989, New Eng. J. Med. 320: 1377-80). The reason why PBC patients have an antigen driven immune response to human PDC-E2 may be partially explained by the findings of immunohistochemical studies. Using monoclonal and combinatorial AMA, PDC-E2 or antigens resembling PDC-E2 have been observed on the surface of cultured PBC biliary epithelium cells (Joplin et al., 1992, Lancet 339: 93-94), biliary epithelium and lymph node macrophages in PBC patient's tissues (Joplin et al., 1991, Hepatology 14: 442-447, Van-de-Water et al., 1993, J. Clin. Invest. 91: 2654-64), and salivary glands of patients with PBC and Sjogrens syndrome (Tsuneyama et al., 1994, Hepatology 20: 893-898). In essence, the tissues affected by the pluriglandular disease process are the same as those with the abnormal distribution of PDC-E2 antigens on epithelial cell surface.

Liver fat accumulation inhibitory composition, food additive for liver fat accumulation, inhibition, and method of inhibiting liver fat accumulation Inventor(s): Imada; Takuma (Saga, JP), Masaki; Kyosuke (Sendai, JP), Noda; Tsuneyuki (Kurume, JP), Shimizu; Seiichi (Otsu, JP), Toba; Masamichi (Tosu, JP) Assignee(s): Otsuka Pharmaceutical Co., Ltd. (Tokyo, JP) Patent Number: 6,468,556 Date filed: March 3, 2000 Abstract: A method of inhibiting liver fat accumulation which comprises administering a conjugated linoleic acid homolog to a mammal or making the mammal ingest it; and a liver fat accumulation inhibitory composition characterized by containing an effective amount of a conjugated linoleic acid homolog together with a support for medicinal preparations or foods. The administration or ingestion of CLA inhibits the total lipid content and the triglyceride content in the liver from increasing, and hence can effectively prevent diseases attributable to fatty liver, such as chronic hepatitis and hepatic cirrhosis. Excerpt(s): The present invention relates to a novel liver fat accumulation inhibitory composition, a food additive for liver fat accumulation inhibition, and a method of inhibiting liver fat accumulation. It has been considered that fatty liver, which is a disease wherein fat is excessively accumulated in the liver (hepatocytes), is caused by supernutrition, hyperingestion of alcohol, diabetes and side effects due to administration of pharmaceuticals, and can cause severe diseases such as chronic hepatitis and hepatic cirrhosis. It is an important subject to treat and prevent fatty liver; however, there have not been accomplished any other safe and effective method for treatment and prevention thereof than control of nutrition to be fed, and there have scarcely been made any development of drugs (pharmaceuticals) for treatment and
Patents 171
prevention. Fatty liver refers to a state where lipid, particularly neutral fat, is accumulated in hepatocytes to the degree exceeding a physiologically permissible range, but a morphological/biochemical clear definition for a quantitative standard of fat deposition has still to be made. In general, fatty liver refers to a case where a remarkable morphological change in accumulation of neutral fat is recognized in hepatocytes over a range of a third of all lobuli and any other remarkable morphological abnormality can not be recognized. From a biochemical point of view, a standard for judgment of fatty liver is that the weight of neutral fat is about 10% (100 mg/g wet weight) or more of the wet weight of hepatic tissue.

Method for measuring cholinesterase and method for distinguishing between liver cirrhosis and hepatitis Inventor(s): Hada; Toshikazu (Ikoma, JP), Kondo; Masahide (Zama, JP), Yasukawa; Kiyoshi (Sagamihara, JP) Assignee(s): Tosoh Corporation (Yamaguchi-Ken, JP) Patent Number: 6,333,162 Date filed: April 17, 1996 Abstract: The object of the present invention is to provide method for discriminating between liver cirrhosis and chronic hepatitis by serodiagnosis using a simple enzyme immunoassay method without performing histopathological examinations by biopsy and so forth.The present invention discloses an enzyme immunoassay method for cholinesterase using monoclonal antibody, a method for detecting Aleuria aurantia lectin-reactive cholinesterase using monoclonal antibody and Aleuria aurantia lectin, and a method for discriminating between liver cirrhosis and chronic hepatitis on the basis of those results. Excerpt(s): The present invention relates to a method for measuring total cholinesterase in, for example, serum; a method for measuring Aleuria aurantia lectin-reactive cholinesterase in, for example, serum; and an in vitro diagnostic method for distinguishing liver cirrhosis, liver carcinoma and hepatitis using those methods. Two types of cholinesterase exist in the body that differ in terms of enzymological properties, physiological function and distribution in the body. Namely, the first is acetylcholinesterase (E.C.3.1.1.7), which specifically breaks down acetylcholine, exists in a large amount in erythrocytes, neural tissue, muscle and so forth, and is distributed in relation to these physiological functions. The other is cholinesterase (also referred to as pseudocholinesterase or butylcholinesterase) (E.C.3.1.1.8), which acts on cholines, such as benzoylcholine and butylcholine, exists in a large amount in the serum and liver, is produced in the liver, and the physiological action of which is considered to most likely be involved with the neuromuscular system. At present, the cholinesterase that is frequently measured in clinical laboratory examinations is cholinesterase in serum (pseudocholinesterase or butylcholinesterase). This enzyme is a glycoprotein having a molecular weight of approximately 340,000 and is composed of four identical subunits. Each subunit is composed of 574 amino acids and has nine asparagine-coupled carbohydrate chains. Clinically, a decrease in its activity, as determined by measuring this enzyme, has significance in terms of determining the degree of functional impairment the liver parenchyma in liver disease, and particularly chronic liver parenchymal disorders such as liver cirrhosis and chronic hepatitis. Since serum cholinesterase is produced in liver parenchymal cells, its decrease indicates a chronic
172 Cirrhosis
functional decrease of liver cells. In addition, acute decreases in cholinesterase activity are observed in cases of poisoning by organic phosphorous-based agricultural chemicals, measurement of the activity of this enzyme is indispensable in these cases. In addition, increases in the activity of this enzyme are observed prominently in nephrotic syndromes. Web site: http://www.delphion.com/details?pn=US06333162__ •
Method for preventing or arresting liver damage in humans Inventor(s): Oren; Ran (2600 Netherland Ave., Riverdale, NY 10463) Assignee(s): none reported Patent Number: 6,143,752 Date filed: July 31, 1998 Abstract: The invention provides methods for treating liver disease by inducing a hypothyroid state using (i) drugs, e.g., PTU, methimazole, lithium or carbimazole; (ii) surgery; or, (iii) radiation, e.g.,.sup.127 I or.sup.131 I. The liver diseases that can be treated using the methods of the invention include: infectious hepatitis, such as (i) viral hepatitis resulting from infection with hepatitis A, D, C, D, E, or G; or (ii) parasitic hepatitis resulting from infection with Schistosoma mansoni, Schistosoma hematobium or Schistosoma japonicum; or (iii) autoimmune disease, e.g., (a) autoimmune hepatitis or (b) primary biliary cirrhosis. Excerpt(s): This invention is directed to methods for preventing, attenuating, retarding or arresting liver damage caused by infection or autoimmune-mediated diseases. The liver is the target of attack for a wide range of diseases. These diseases include infectious, autoimmune, as well as non-infectious processes such as chemicals. Examples of infectious diseases include: (i) viral hepatitis, e.g., hepatitis A, B, C, D, E, and G and (ii) parasitic hepatitis, e.g., Schistosoma mansoni, Schistosoma hematobium, and Schistosoma japonicum. (Harrison's Principles of Internal Medicine, Fauci et al. eds., 1998, pgs 1660-1725). Examples of noninfectious diseases affecting the liver, include autoimmune diseases, such as, (i) autoimmune hepatitis and (ii) primary biliary cirrhosis. (Harrison's Principles of Internal Medicine, Fauci et al. eds., 1998, pgs 17011709). Regardless of whether the attack on the liver is infectious, autoimmune or noninfectious, the liver responds to injury by pouring inflammatory cells into the site of attack. The types of inflammatory cells entering the site of attack consist primarily of macrophages and neutrophils. After entry into the site of injury, the cells release various inflammatory cytokines, such as tumor necrosis factor (TNF). These cytokines mediate the local inflammatory response by inducing local changes, for example, proliferation of fibroblasts or vasodilation. If left untreated, repeated, chronic damage to the liver from infection, autoimmune disease or any other noninfectious processes causes scarring or fibrosis. This is a direct consequence of local proliferation of fibroblasts. (Kaplowitz, Biliary Diseases, pg. 139, Williams & Wilkins, 1992). In the case of the liver, the endstage of fibrosis is cirrhosis. Pathologically, cirrhosis is defined as extensive fibrosis in the liver in association with the formation of regenerative nodules. Cirrhosis is the final common pathway for many, if not all, types of chronic liver damage and is typically progressive. (Kaplowitz, Biliary Diseases, pg. 140, Williams & Wilkins, (1992).

Non-malignant disease treatment with Ras antagonists Inventor(s): Brownstein; Michael (Rockville, MD), Bruck; Rafael (Rishon Le-Zion, IL), Chapman; Joab (Kiryat Ono, IL), Karussis; Dimitrius (Jerusalem, IL), Kloog; Yoel (Herzliya, IL), Reif; Shimon (Karney Shomron, IL) Assignee(s): Ramot University Authority for Applied Research and Industrial Development (IL) Patent Number: 6,462,086 Date filed: June 19, 2000 Abstract: Disclosed is a method for inhibiting Ras-induced or mediated proliferation of cells associated with a non-malignant disease, disorder or pathological condition. The method entails administering to a patient a Ras antagonist in an amount effective to inhibit the proliferation. The invention is particularly applicable to diseases characterized by a proliferation of T-cells such as autoimmune disease, e.g., type 1 diabetes, lupus and multiple sclerosis, and pathological states such as graft rejection induced by the presentation of a foreign antigen such as a graft in response to a disease condition (e.g., kidney failure). Other non-malignant diseases characterized by proliferations of cells include cirrhosis of the liver and restenosis. Preferred Ras antagonists are S-trans-trans farnesylthiosalicylic acid (FTS) and structurally related compounds (or analogs) thereof.
174 Cirrhosis
Excerpt(s): The present invention relates to the inhibition of the onset of or the treatment of non-malignant diseases, and particularly diseases having pathologies involving Rasinduced proliferation of cells. Autoimmune diseases include disorders involving dysfunction of the immune system, which mediates tissue damage. Any organ may be affected by such processes through precipitation of immune complexes, cellular immunity, or inappropriate generation or action of immuno-hormones such as cytokines. Epidemiologically, autoimmune diseases are significant because of the numbers of patients that they affect and the serious morbidity and mortality that they cause. Common chronic systemic diseases in this group include diabetes mellitus, thyroid disease, rheumatoid arthritis, systemic lupus erythematosus (SLE), primary antiphospholipid syndrome (APS), and a variety of diseases that affect the central nervous system. Neurological autoimmune diseases include disorders specific to the nervous system such as myasthenia gravis, Lambert Eaton myasthenic syndrome, Guillain-Barre syndrome, polymyositis, and multiple sclerosis. In addition, there are neurological complications of the systemic autoimmune diseases. Factors predisposing to autoimmune diseases include genetic predisposition and environmental agents such as certain infections and pharmaceutical products. Such factors result in pathological activation of the immune response in susceptible individuals, which is generally controlled by T lymphocytes (T cells). The activation T cells and B subtypes, involves a complex interaction of cell surface receptors resulting in equally complex signal transduction pathways which eventually affect gene regulation. Full activation of lymphocytes requires parallel stimulation of several signal transduction pathways. See Ohtsuka, et al., Biochim. Biophys. Acta. 1310:223-232 (1996). Although there is growing understanding about the function of T cells in the immune response, this knowledge has not explained the basis of most autoimmune diseases. There are still questions to be resolved such as how tolerance to self in normal individuals is maintained; how tolerance is broken in autoimmunity; and which autoantigens trigger the immune system to produce specific diseases. A recent review by V. Taneja and C. S. David (J. Clin. Invest. 101:921-926 (1998)) provides an overview of important issues in this field and emphasized how the generation of transgenic mice expressing functional HLA molecules is important for understanding the function of certain molecules in the induction of autoimmune disease, as well as circumvention of the xenogenic barrier. Regardless of the mechanisms involved in induction of autoimmune disease or the rejection of grafts, the common pathway for these events includes activation of a relatively small number of T lymphocytes.

Nucleic acids encoding proteins for early liver development Inventor(s): Mishra; Lopa (6910 Oakridge Ave., Bethesda, MD 20815) Assignee(s): none reported Patent Number: 5,955,594 Date filed: April 30, 1997 Abstract: Early developing stage-specific liver proteins and the genes coding for them that have been isolated and sequenced are provided, and these genes and proteins can be utilized to diagnose and/or treat a wide variety of liver disorders and other ailments. Included in the proteins identified and isolated in the present invention are the proteins known as elf 1-3, liyor-1 (145), pk, protein 106, and praja-1, along with the nucleic acid sequences coding for these and other proteins. Since the early developing liver proteins
Patents 175
of the invention arise during embryogenesis when the liver and other organs are in transition from an undifferentiated state to a differentiated one, these proteins are involved in tissue differentiation and thus can be utilized in methods of diagnosing and treating a variety of liver diseases and other disorders including those relating to oncogenesis and tissue repair. Accordingly, the isolated early developing liver proteins in accordance with the present invention should have implications for diagnosis and treatment of a range of diseases from end stage cirrhosis to hepatocellular carcinoma and many other disease conditions. Excerpt(s): This invention relates to proteins isolated during early liver development and the genes coding for them, and to methods for their use in diagnosing and treating liver disease and other disorders. In the United States and other countries, end stage liver disease due to infection, genetic defects or alcoholic consumption is a major cause of widespread morbidity and mortality, causing great potential hardship and economic loss to millions of people throughout the world. In addition, numerous other diseases, including biliary problems and blood disorders, are associated with disruptions in the many functions carried out by the liver, including iron transport, hepatocyte formation and hematopoiesis. In general, severe problems associated with a breakdown of liver function are practically untreatable, and require a liver transplant as the only cure. However, in light of the great disparity between the number of patients needing liver transplants and the number of donors, thousands upon thousands of people are denied this operation, and transplantation is at the present time not a practical approach to the problem. At the same time, the precise nature of liver development and the role of early developing liver proteins has not been well understood. To date, no growth factors specific to the liver have been identified or isolated, and the precise molecular mechanisms behind hepatocyte (liver cell) formation remain to be elucidated. There thus has been a long felt need to identify and understand the changes in gene regulation and expression in the developing liver, including the determination as to which genes are switched on and off as a hepatocyte forms and a liver develops. Accordingly, isolating and identifying the genes and proteins which play critical roles in early liver development would be beneficial in understanding the effect of gene regulation and expression in the differentiating liver, and in diagnosing and treating many diseases states involving the liver and liver functions.

The invention also relates to the use of particular vitamins, amino acids, trace elements and ubiquinone for the preparation of a medicament suitable for the treatment of such liver disorders. Primary biliary cirrhosis is a chronic cholestatic liver disease with an autoimmune aetiology which results in the destruction of the bile ducts in the liver. The disease is progressive in nature, with a significant proportion of affected patients going on to develop cirrhosis with all its sequelae. Females are more commonly affected, with approximately 90% of all cases of PBC occurring in females. This disease has been diagnosed in patients as young a 23 years and as old as 72. The majority of cases are diagnosed in the 40-60 age group. Web site: http://www.delphion.com/details?pn=US06136859__ •
Polynucleotide encoding human serpin Inventor(s): Holloway; James L. (Seattle, WA) Assignee(s): ZymoGenetics, Inc. (Seattle, WA) Patent Number: 6,524,822 Date filed: November 20, 2000 Abstract: Members of the serine protease family play a role in carefully controlled processes, such as blood coagulation, fibrinolysis, complement activation, fertilization, and hormone production. The enzymatic activity of the serine proteases is regulated in part by serpins, serine protease inhibitors. Serpin dysfunction is associated with various disorders, including emphysema, blood clotting disorders, cirrhosis, Alzheimer disease, and Parkinson disease. Zserp11 is a new member of the serine protease inhibitor family. Excerpt(s): The present invention relates generally to a new gene that encodes an enzyme inhibitor. In particular, the present invention relates to a novel serpin, designated "Zserp11," and to nucleic acid molecules encoding Zserp11. Endogenous proteolytic enzymes provide a variety of useful functions, including the degradation of invading organisms, antigen-antibody complexes, and certain tissue proteins that are no longer necessary. The serine proteases comprise a large family of enzymes that use an activated serine residue in the substrate-binding site to catalytically hydrolyze peptide bonds. Typically, this serine residue can be identified by the irreversible reaction of its side chain hydroxyl group with diisopropylfluorophosphate. Serine proteases participate in carefully controlled processes, such as blood coagulation, fibrinolysis, complement activation, fertilization, and hormone production. Normally, serine proteases catalyze limited proteolysis, in that only one or two specific peptide bonds of the protein substrate are cleaved. Under denaturing conditions, serine proteases can hydrolyze multiple peptide bonds, resulting in the digestion of peptides, proteins, and even autolysis. Several diseases are thought to result from the lack of regulation of serine protease activity, including emphysema, arthritis, cancer metastasis, and thrombosis.

Therapeutic agent for primary biliary cirrhosis Inventor(s): Nishiguchi; Shuhei (Osaka, JP), Sounaka; Ichirou (Kawasaki, JP) Assignee(s): Ajinomoto Co., Inc. (Tokyo, JP), The City of Osaka (Osaka, JP) Patent Number: 6,339,104 Date filed: October 16, 2000 Abstract: Disclosed is a therapeutic agent for primary biliary cirrhosis, which contains L-alanine or a pharmaceutically acceptable salt thereof as the active ingredient. The effect of this therapeutic agent is to reduce serum total bilirubin and transaminase value, thereby effectively curing primary biliary cirrhosis. This therapeutic agent can be chronically administrated for a long period of time and exhibits an effect superior to that obtained in ordinary medical therapy. Excerpt(s): The present invention relates to a therapeutic agent for primary biliary cirrhosis. Primary biliary cirrhosis is a liver disease of unknown etiology of middleaged women, which slowly advances and has, as a background, immunologic abnormality and chief complaints of fatigue, pruritus, jaundice, etc. Primary biliary cirrhosis is an intractable disease different from other diseases in both pathology and method of treatment. Concretely, alcohol-induced liver disease is caused by the intake of alcoholic drinks, and abstinence from alcoholic drinks is the primary selective treatment. The action of alanine contained in "antagonistic composition alcohol-induced hepatopathy" which will be described below is to accelerate the alcohol catabolism. Hepatitis, which is not induced by alcoholic drinks, is caused by virus of type A, B or C or by the intake of a large amount of a medicine or the intake of the medicine for a long period of time. For the treatment of hepatitis of such a type, interferon therapy is employed or strong Neo-Minophagen C is used for the treatment. The action of alanine contained in "therapeutic agents for hepatitis" which will be cited below is to inhibit the increase of transaminase by improving the mitochondria function. When these alcoholinduced hepatopathy and hepatitis become chronic, they develop into liver cirrhosis. As for the therapy for liver cirrhosis, only symptomatic therapy for hepatic encephalopathy, hypoalbuminemia and hemorrhage of digestive tracts is possible. However, no therapeutic method for curing liver cirrhosis itself or for inhibiting the advance thereof was developed and, as for alanine, its therapeutic effect on liver cirrhosis is unknown yet. On the other hand, primary biliary cirrhosis is a liver cirrhosis caused by cholestasis of unknown origin. After the outbreak of the disease, its progress is relatively slow. However, in many of the cases where the symptoms have already been shown, the disease reaches liver cirrhosis in 4 years and the patients die of hepatic insufficiency in about 5 years on average. Patients with primary biliary cirrhosis are thus not convalescing satisfactorily. Although ursodeoxycholic acid is used as the first selective medicine in the treatment of primary biliary cirrhosis, the therapeutic effect thereof is weakened as the conditions of the patients advance. In those advanced stages of diseases, cases in which the symptoms became more serious by the administration of ursodeoxycholic acid were reported. Further, because this disease surely progresses into hepatic insufficiency, patients having the terminal symptoms are obliged to rely on liver transplantation. However, the transplantation has problems such as insufficiency of the organs. Under these circumstances, the development of a medical drug therapy capable of controlling the symptoms and delaying the advance of the disease is demanded. Although it was known to use alanine alone or in combination with other amino acids for preparing a composition for treating patients suffering from alcohol-induced disorders [Japanese Patent Unexamined Published Application (hereinafter referred to as "J. P. KOKAI" No. Sho 63-54320), a composition for treating

Treatment of disease states Inventor(s): Gurney; Harry C. (Conifer, CO), McMichael; John (Delanson, NY) Assignee(s): Milkhaus Laboratory, Inc. (Delanson, NY) Patent Number: 6,303,127 Date filed: August 11, 1998 Abstract: The invention presents methods for the treatment of symptoms associated with diseases states including cardiomyopathy, Parkinson's Disease and degenerative liver disease including cirrhosis comprising treatment with an effective amount of a composition comprising beta-amyloid, streptolysin O, and growth hormone. Excerpt(s): This invention relates generally to methods and materials for the treatment and amelioration of the symptoms associated with cardiomyopathy in non-human animals, Parkinson's Disease, and degenerative liver disease including cirrhosis. Cardiomyopathy is a disease of the heart muscle. This form of heart disease is often distinctive, both in general symptoms and in patterns of blood flow, to allow a diagnosis to be made. Increasing recognition of this disease, along with improved diagnostic techniques, has shown that cardiomyopathy is a major cause of morbidity and mortality. In some areas of the world it may account for as many as 30 percent of all deaths due to heart disease. Cardiomyopathy can result from a variety of structural or functional abnormalities of the ventricular myocardium. A large number of cardiomyopathies are apparently not related to an infectious process and are not well understood. Some are congenital and may cause enlargement of the heart. Metabolic diseases associated with endocrine disorders may also cause cardiomyopathies. Infections, such as acute rheumatic fever and several viral infections, may cause a number of types of myocarditis. Myocarditis may also occur as a manifestation of a generalized hypersensitivity reaction, allergic or immunologic. The heart may also be affected by any of a considerable number of collagen diseases. Collagen is the principal connective tissue protein, and collagen diseases are diseases of the connective tissues. They include diseases primarily of the joints, skin, and systemic disease.

Abstract: A composition for treating hepatic fibrosis and a method of using and manufacturing the composition are provided. The composition includes a quinazolinone derivative, preferably Halofuginone. Excerpt(s): The present invention relates to the treatment of hepatic cirrhosis and, in particular, to the treatment of hepatic cirrhosis with quinazolinone derivatives such as Halofuginone. Hepatic cirrhosis has a number of causes, including hepatic fibrosis caused by chronic alcoholism, malnutrition, hemochromatosis, passive congestion, hypercholesterolemia, exposure to hepatotoxic chemical substances, exposure to drugs, immune reactions, genetically determined sensitivities to certain substances as seen with copper in Wilson's disease and infections such as viral hepatitis, syphilis and various parasitic infections including, but not limited to, Schistosomiasis mansoni and S. japonica. For reasons given in greater detail below, the disease is currently incurable and frequently fatal. The pathogenesis of hepatic cirrhosis progresses in a number of stages. First, an enlarged liver is seen with various fatty changes. Next, overt fibrosis is evident with a concomitant decrease in liver function. Finally, atrophy of the liver begins, with a corresponding reduction in the size and functionality of the liver. Necrosis of the liver can be seen at any stage, but is particularly pronounced by late stage cirrhosis. Microscopically, a complete disruption of the normal architecture of the liver is evident.

Excerpt(s): Endothelial NO synthase (eNOS, NOS-III) belongs to a group of three isoenzymes which produce nitric oxide (NO) by oxidation of arginine. Endothelially released NO is of central importance in a number of key cardiovascular mechanisms. It has a vasodilating effect and inhibits the aggregation of platelets, the adhesion of leukocytes to the endothelium and the proliferation of intimal smooth muscle cells. Endothelial NO synthase is subject to physiological and pathophysiological regulation both at the transcriptional and at the post-transcriptional level. Enzyme already present in the endothelium may undergo calcium-dependent and calcium-independent activation through phosphorylation of specific amino acids, but also by direct interactions with specific proteins. Stimulators of this, usually transient, NO release are, extracellular arginine, 17.beta.-estrogen and the mechanical stimulus exerted on the luminal surface of the endothelium by the blood flow (shear stress). The latter additionally leads to regulation of eNOS at the transcriptional level. Thus, for example, Sessa et al. (Circ. Research 74 (1994) 349-353) were able by means of exercise training and the increase in shear stress associated therewith to obtain a marked increase in ecNOS. Whether regulation at the post-transcriptional level is relevant in vivo, is not unambiguously proved. Thus, for example, administration of a high arginine dose is followed by only a transient improvement in the endothelium-dependent vasorelaxation in patients with coronary heart disease.

Composition and method for treating nonalcoholic steatohepatitis Inventor(s): Fan, David; (Newport Beach, CA), Hsia, Houn Simon; (Irvine, CA) Correspondence: Lyon & Lyon Llp; Suite 4700; 633 West Fifth Street; Los Angeles; CA; 90071-2066; US Patent Application Number: 20010000028 Date filed: November 29, 2000 Abstract: Nonalcoholic steatohepatitis (NASH) is a disease of the liver characterized by inflammation and damage to the liver cells. Typically, steatohepatitis involves inflammation of the liver related to fat accumulation, and mimics alcoholic hepatitis but is observed in patients who seldom or never consume alcohol. Nonalcoholic steatohepatitis can lead to serious liver damage, and ultimately cirrhosis. The present invention provides methods and compositions useful for the treatment or alleviation of nonalcoholic steatohepatitis and the pharmaceutical formulations for their administration to a human. Specifically, compositions comprised of lecithin, antioxidants and vitamin B complex are administered parenterally, most preferably by oral administration. Specific therapeutic formulations include admixtures of these compounds and specific dosage formulations include daily oral administrations of these compounds in tablet or powder forms. Excerpt(s): 1. This is a divisional of co-pending application Ser. No. 09/205,082, filed on Dec. 4, 1998. The priority of the prior application is expressly claimed, and the disclosure of each of this prior application is hereby incorporated by reference in its entirety. 2. The present invention generally relates to dietary supplements containing lecithin, antioxidants and/or a vitamin B complex to treat liver disease. A preferred embodiment is a composition and the use thereof of a dietary supplement comprising lecithin, at least one antioxidant, and a vitamin B complex administered orally to treat or alleviate nonalcoholic steatohepatitis. 3. The liver is the largest organ in the human body, located in the superior portion of the right upper abdomen. This organ is highly complex and specialized and performs many crucial biochemical functions. The liver is critically involved in the removal of toxins from the body and in the manufacture of proteins including energy storage and blood clotting factors. The liver is also involved in storing minerals, vitamins and glucose in the form of glycogen, which is metabolized in large quantities to provide energy. The liver also plays a role in red blood cell metabolism and the break-down of certain metabolic byproducts in the blood stream. Web site: http://appft1.uspto.gov/netahtml/PTO/search-bool.html

Compounds for inhibition of ceramide-mediated signal transduction Inventor(s): Carson, Dennis A.; (Del Mar, CA), Cottam, Howard; (Fallbrook, CA) Correspondence: Schwegman, Lundberg, Woessner & Kluth, P.A.; P.O. Box 2938; Minneapolis; MN; 55402; US Patent Application Number: 20020165202 Date filed: September 13, 2001

Abstract: Novel, heterocyclic compounds having at least one ring nitrogen, disclosed side chains and, in some embodiments, an oxygen ortho to the ring nitrogen inhibit inflammatory responses associated with TNF-.alpha. and fibroblast proliferation in vivo and in vitro. The compounds of the invention neither appreciably inhibit the activity of cAMP phosphodiesterase nor the hydrolysis of phosphatidic acid, and are neither cytotoxic nor cytostatic. Preferred compounds of the invention are esters. Methods for the use of the novel compounds to inhibit ceramide-mediated intracellular responses in stimuli in vivo (particularly TN-.alpha.) are also described. The methods are expected to be of use in reducing inflammatory responses (for example, after angioplasty), in limiting fibrosis (for example, of the liver in cirrhosis), in inhibiting cell senescence, cell apoptosis and UV induced cutaneous immune suppression. Compounds having enhanced water solubility are also described. Excerpt(s): This application is a continuation-in-part of U.S. patent application Ser. No. 08/367,102, filed Dec. 29, 1994 and a continuation-in-part of U.S. patent application Ser. No. 08/482,551, filed Jun. 7, 1995. The invention relates to compounds effective in modulating cellular responses stimulated by ceramide-mediated signal transduction, in particular in response to stimulus by the cytokine tumor necrosis factor.alpha. (TNF.alpha.). More specifically, it relates to compounds which inhibit the development of conditions associated with cell stimulus through the ceramide-mediated signal transduction pathway. The sphingomyelin pathway is a cellular signal transduction pathway that is believed to be involved in mediating cellular responses to several cytokines (including TNF-.alpha. and IL-I.beta.) and growth factors (e.g., platelet derived growth factor and fibroblast growth factor) (see, e.g., Dressier, et al., Science, 259:1715-1718, 1992; and, Jacobs and Kester, Amer.J.Physiol., 265: 740-747, 1993). It is believed that interaction of such molecules with cell surface receptors triggers activation of a plasma membrane sphingomyelinase. Sphingomyelinase in turn catalyzes the hydrolysis of sphingomyelin to deramide and phosphocholine. Ceramide is believed to act as a second messenger through activation of a proline-directed, serine/threonine kinase (ceramide-activated protein kinase or "CaPK"). Ceramide also interacts with MAP kinase and protein kinase C zeta (see, e.g., Rivas, et al., Blood, 83:2191-2197, 1993) and with a serine/threonine protein phosphatase (see, Hannun, et al., TIBS, 20:73-77, 1995).

R.sup.1 and R.sup.2 may be joined together to form a cycloalkyl ring, n is an integer having the value 0 or 1, provided that when n is 0, Y stands for the oxygen or sulphur atom or for the sulphonyl (--SO.sub.2--) radical, or an ester, amide or salt thereof. Excerpt(s): This invention relates to fibrotic diseases. There are many fibrotic diseases in the human. These are sometimes referred to as chronic connective tissue diseases, and include degradative and proliferative conditions. They include, for example, deterioration of the joints in arthritis, deformation of vessel walls in artherosclerosis, accelerated cardiovascular problems associated with diabetes, lung fibrosis and cirrhosis of the liver. These fibrotic diseases are generally considered and studied as separate and different problems However, it is possible that common pathways exist in all these fibrotic diseases Indeed, corticosteriods are used in the treatment of many of these diseases to relieve symptoms and prevent associated tissue destruction and scarring; however, the use of corticosteroids is associated with dose and treatment duration side-effects which limit the usefulness of this type of compound. Some fibrotic diseases are particularly distressing, such as, for example, those involving deterioration of cartilage and bone in the joint. Amelioration of such diseases is a particularly difficult target for the pharmaceutical industry. These conditions are often accompanied by distressing levels of pain and gradual impairment of structural body function and movement. An added difficulty in attempting to find a satisfactory cure or improvement is that joint disease appears to be largely species specific. Therefore, research into joint disease in man is made more difficult in that animal models may not be appropriate. Web site: http://appft1.uspto.gov/netahtml/PTO/search-bool.html •
Epoxy-steroidal aldosterone antagonist and calcium channel blocker combination therapy for treatment of congestive heart failure Inventor(s): Schuh, Joseph R.; (St. Louis, MO) Correspondence: Pharmacia Corporation; Corporate Patent Law Department; Mail Zone O4e; 800 North Lindbergh BLVD.; ST.

Myocardial
184 Cirrhosis
(or cardiac) failure, whether a consequence of a previous myocardial infarction, heart disease associated with hypertension, or primary cardiomyopathy, is a major health problem of worldwide proportions. The incidence of symptomatic heart failure has risen steadily over the past several decades. In clinical terms, decompensated cardiac failure consists of a constellation of signs and symptoms that arises from congested organs and hypoperfused tissues to form the congestive heart failure (CHF) syndrome. Congestion is caused largely by increased venous pressure and by inadequate sodium (Na.sup.+) excretion, relative to dietary Na.sup.+ intake, and is importantly related to circulating levels of aldosterone (ALDO). An abnormal retention of Na.sup.+ occurs via tubular epithelial cells throughout the nephron, including the later portion of the distal tubule and cortical collecting ducts, where ALDO receptor sites are present.

Human FGF-21 gene and gene expression products Inventor(s): Itoh, Nobuyuki; (Kyoto, JP), Kavanaugh, W. Michael; (Mill Valley, CA) Correspondence: Seed Intellectual Property Law Group Pllc; 701 Fifth Ave; Suite 6300; Seattle; WA; 98104-7092; US Patent Application Number: 20020164713 Date filed: January 29, 2002 Abstract: This invention relates to human fibroblast growth factor (hFGF-21), and to variants thereof and to polynucleotides encoding FGF-21. The invention also relates to diagnostic and therapeutic agents related to the polynucleotides and proteins, including probes and antibodies, and to methods of treating liver disease such as cirrhosis and cancer, methods of treating conditions related to thymic function, and methods of treating conditions of the testis. The invention also relates to mouse fibroblast growth factor (mFGF-21), and to variants thereof and polynucleotides encoding mFGF-21. Excerpt(s): This application claims priority from U.S. Provisional Patent Application No. 60/166,540 filed Nov. 18, 1999 and U.S. Provisional Patent Application No. 60/203,633 filed May 11, 2000, which are incorporated by reference herein in their entirety. The present invention relates to nucleic acid sequences encoding a member of the fibroblast growth factor (FGF) family, and to polypeptides encoded by the nucleic acid sequence. The prototypic fibroblast growth factors (FGFs), FGF-1 and FGF-2, were originally isolated from brain and pituitary as mitogens for fibroblasts. However, FGF-1 and FGF-2 are widely expressed in developing and adult tissues, and are polypeptides with multiple biological activities including angiogenesis, mitogenesis, cellular differentiation and repair of tissue injury (Baird, A. et al., Cancer Cells 3:239-243 (1991); Burgess, W. H. et al., Annu. Rev. Biochem. 58:575-606 (1989). According to the published literature, the FGF family now consists of at least nineteen members, FGF-1 to FGF-19. FGF-3 was identified to be a common target for activation by the mouse mammary tumor virus (Dickson et al., Ann. N.Y. Acad. Sci. 638:18-26 (1991); FGF-4 to FGF-6 were identified as oncogene products (Yoshida et al., Ann. NY Acad. Sci. 638:27-37 (1991); Goldfarb et al., Ann. NY Acad. Sci 638:38-52 (1991); Coulier et al., Ann. NY Acad. Sci. 638:53-61 (1991)). FGF-10 was identified from rat lung by homology-based polymerase chain reaction (PCR) (Yamasaki et al., J. Biol. Chem. 271:15918-15921 (1996)). FGF-11 to FGF-14 (FGF homologous factors (FHFs) 1 to 4) were identified from human retina by a combination of random cDNA sequencing, data base searches and homology-based PCR (Smallwood et al., Proc. Natl. Acad. Sci. USA 93:9850-9857 (1996)). FGF-15 was identified as a downstream target of a chimeric homeodomain oncoprotein (McWhirter et al., Development 124:3221-3232 (1997)). FGF-16, FGF-17, and FGF-18 were identified from rat heart and embryos by homology-based PCR, respectively (Miyake et al., Biochem. Biophys. Res. Commun. 243:148-152 (1998); Hoshikawa et al., Biochem. Biophys. Res. Commun. 244:187-191 (1998); Ohbayashi et al., J. Biol. Chem. 273:18161-18164 (1998)). Recently, FGF-19 was identified from human fetal brain by data base search (Nishimura et al., Biochim. Biophys. Acta 1444:148-151 (1999)). They have a conserved.about.120amino acid residue core with.about.30 to 60% amino acid identity. These FGFs also appear to play important roles in both developing and adult tissues. Thus, there is a need in the art for additional FGF molecules having functions and activities that differ from the known FGFs and for FGF molecules specifically expressed in tissues implicated in human disease.

Immunomodulator Inventor(s): Hamuro, Junji; (Kawasaki-shi, JP), Murata, Yukie; (Kawasaki-shi, JP) Correspondence: Oblon, Spivak, Mcclelland, Maier & Neustadt, P.C.; 1940 Duke Street; Alexandria; VA; 22314; US Patent Application Number: 20030203006 Date filed: April 3, 2003 Abstract: An immunomodulator is provided which is capable of oral intake for improvement, treatment and prevention of human immunological diseases and which is used to treat, improve and prevent human immunological diseases, especially, autoimmune diseases and allergic diseases such as hepatic cirrhosis, hepatitis, diabetes, inflammatory bowel diseases, chronic rheumatoid arthritis, asthma and cutaneous atopy, allergic diseases and cancers by a new method that can control the redox state of macrophages or monocytes, and can be incorporated into a drug, a food, a nutrient, and an infusion. The contents of oxidative glutathione and reductive glutathione in macrophages are monitored, and the ratio of oxidative glutathione and reductive glutathione is examined, whereby macrophages are classified into oxidative macrophages and reductive macrophages having different functions. The degree of progression of various autoimmune diseases is analyzed from this standpoint. On the basis of the results, an immunomodulator capable of oral intake which contains a substance having an activity of changing a content of reductive glutathione in macrophages to solve the above-mentioned problem and which is intended to treat, improve and prevent human immune diseases is provided. Excerpt(s): The present invention relates to a novel immunomodulator. More specifically, the present invention relates to an immunomodulator capable of oral intake which has a novel suppressive function of macrophages (hereinafter sometimes abbreviated as "M.PHI.") or monocytes. The immunomodulator may be used for treatment, improvement and prevention of human autoimmune diseases such as hepatic cirrhosis, hepatitis, diabetes, inflammatory bowel diseases, chronic rheumatoid arthritis, asthma and cutaneous atopy, allergic diseases and cancers. The present invention also relates to a drug, a food, a nutrient and an infusion containing the immunomodulator. As used herein, the term "immune system" refers to one's bodily system for defending itself from exogenous infection by virus, bacteria or the like, or from invasion the body with transformed cells (tumor cells and the like) formed by transformation of autologous cells. However, the immune system occasionally behaves abnormally, i.e., it functions excessively and acts to reject autologous components. On the other hand, the immune system sometimes functions deficiently, resulting in an immunocompromised state. Diseases revealing these abnormal responses are generally called immunological diseases. Examples thereof include diverse diseases, such as, for example, acute or chronic inflammatory diseases such as atopic cutaneous inflammatory diseases, pollinosis, asthma and sarcoidosis; autoimmune diseases such as allergic diseases, chronic rheumatoid arthritis, diabetes, SLE and chronic fatigue syndrome; hepatitis, hepatic cirrhosis, inflammatory bowel diseases (IBD) such as ulcerative colitis and Crohn's disease; and cancer cachexia. These immunological diseases originate from complex pathological causes. Systemic immunodeficiency and functional deficiency originate from pathological inflammation accompanied by cell proliferation, differentiation or cell necrosis through local production of cytokines or inflammatory mediators. As cells that participate in immunity, T lymphocytes and B lymphocytes are well known, exhibiting a wide variety of functions as cells playing roles in cellular immunity and humoral immunity respectively. Meanwhile, macrophages and
Patents 187
monocytes are cells that intimately participate in both cellular immunity and humoral immunity, and they intimately participate in rejection of non-self foreign bodies, for example, immunological diseases such as allergy and rheumatism, cancers and bacterial infection.

Lectins as anti-fibrotic agents Inventor(s): Cantor, Jerome Owen; (Brooklyn, NY), Shteyngart, Bronislava; (Brooklyn, NY) Correspondence: Jerome O. Cantor, MD; 242 92nd Street; Brooklyn; NY; 11209; US Patent Application Number: 20030216300 Date filed: May 12, 2003 Abstract: The subject invention is directed to the treatment of tissue fibrosis by administration of an effective amount of lectin. Fibrosis herein refers to the accumulation of extracellular matrix constituents that occurs following trauma, inflammation, tissue repair, immunological reactions, cellular hyperplasia, and neoplasia. Examples of tissue fibrosis include, but are not limited to, pulmonary fibrosis, cirrhosis of the liver, skin scars and keloids, adhesions, fibromatosis, atherosclerosis, and amyloidosis. The treatment is intended for a variety of mammals, including humans. Excerpt(s): Lectins bind to carbohydrate moieties, e.g. acetylglucosamine, that are ubiquitous in the mammalian extracellular matrix. This suggests the possibility that lectins may be used to coat the matrix and limit further binding of collagen, elastin, and other connective tissue components to carbohydrate groups. The aggregation of large amounts of matrix constituents, as occurs in fibrosis, may therefore be subject to limitation by the introduction of lectins. This hypothesis was tested in our laboratory. Elastic fiber matrix prepared from cultured rat lung mesothelial cells (1,2) was first treated with tomato lectin (lycopersicon esculentum), then covered with hyaluronan (HA), which normally protects the matrix from degradation by elastases. It was found that lectin treatment abolished the protective effect of HA and facilitated breakdown of the elastic fiber matrix by elastase. Since the binding of HA to the elastic fibers is analogous to fibrosis in that it involves deposition of new matrix material (HA) over existing matrix, the addition of lectin may provide a means of counteracting this process and preventing the formation of scar tissue.

Novel long-term three-dimensional tissue culture system Inventor(s): Bowen, William C.

Disclosed are methods and compositions for ex vivo culturing of hepatocytes and
188 Cirrhosis
nonparenchymal cells on a matrix coated with a molecule that promotes cell adhesion, proliferation or survival, in the presence of growth factors, resulting in a long-term culture of proliferating hepatocytes that retain hepatic function. The co-culturing method results in the formation of matrix/hepatic cell clusters that may be mixed with a second structured or scaffold matrix that provides a three-dimensional structural support to form structures analogous to liver tissue counterparts. The hepatic cell culture system can be used to form bio-artificial livers through which a subjects blood is perfused. Alternatively, the novel hepatic cell culture system may be implanted into the body of a recipient host having a hepatic disorder. Such hepatic disorders, include, for example, cirrhosis of the liver, induced hepatitis, chronic hepatitis, primary sclerosing cholangitis and alpha.sub.1 antitrypsin deficiency. The present invention is based on the discovery that mixed cultures of proliferating hepatocytes and nonparenchymal cells, grown on a collagen-coated matrix in medium containing hepatocyte growth factor (HGF) and epidermal growth factor (EGF), maintain their capacity to proliferate while retaining hepatic functions. Further, it was discovered that addition of corticosteroids to the media resulted in phenotypic maturation of hepatocytes. One of the major functions of the liver is to break down harmful substances absorbed from the intestine or manufactured elsewhere in the body, followed by their excretion as harmless byproducts into the bile or blood. Abnormalities of liver function caused by insult to and/or death or malfunction of the cells in the liver can lead to a variety of different hepatic disorders including cirrhosis of the liver or hepatitis. Treatment of such disorders may include whole liver transplants, although this treatment is limited by organ availability, surgical complications, and immunologically-mediated graft rejection normally associated with liver transplantation.

Excerpt(s): This application claims priority from U.S. Ser. No. 60/243,817, filed Oct. 27, 2000. This invention relates to novel substituted benzimidazol-2-ones. More particularly, the compounds of the present invention modulate the binding of the peptide hormone vasopressin and neuropeptide Y to their respective receptors and are therefore useful for
Patents 189
treating conditions involving increased vascular resistance, cardiac insufficiency, and disorders of energy metabolism. Vasopressin is a nonapeptide hormone that is secreted primarily from the posterior pituitary gland. The hormone effects its actions through the vascular V-1 and renal V-2 receptor subtypes. The functions of vasopressin include contraction of uterine, bladder, and smooth muscle; stimulation of glycogen breakdown in the liver; induction of platelet aggregation; release of corticotropin from the anterior pituitary and stimulation of renal water reabsorption. As a neurotransmitter within the central nervous system (CNS), vasopressin can affect aggressive behavior, sexual behavior, the stress response, social behavior and memory. The V-1a receptor mediates central nervous system effects, contraction of smooth muscle and hepatic glycogenolytic effects of vasopressin, while the V-1b receptor mediates anterior pituitary effects of vasopressin. The V-2 receptor, presumably found only in the kidney, effects the antidiuretic actions of vasopressin via stimulation of adenylate cyclase.

Prevention of liver cancer by administration of simvastatin Inventor(s): Weinberg, Assa; (Los Angeles, CA) Correspondence: Dave B. Koo, ESQ.; Squire, Sanders & Dempsey L.L.P.; 801 S. Figueroa Street, 14th Floor; Los Angeles; CA; 90017-5554; US Patent Application Number: 20020151583 Date filed: April 11, 2001 Abstract: A method for preventing liver cancer is disclosed. In one embodiment, the method comprises administrating an effective amount of simvastatin to patients showing elevated alphafetoprotein levels. In another embodiment, the method comprises administrating simvastatin to patients upon detection of a liver condition, i.e viral Hepatitis B, Hepatitis C and liver cirrhosis. Excerpt(s): In spite of substantial advances in the understanding of the mechanism of oncogenesis (transformation of a normal cell into a malignant one), a method to prevent and reverse such oncogenic process has not been put into practice. Many environmental, dietary and genetic factors play a significant role in the formation of a malignant tumor, but no drug is known to prevent the formation of a malignant tumor. In many cases, patients affected with a malignant tumor are deemed to be terminal. Cancer of the liver or hepatocellular carcinoma is a particular case in point. It is an aggressive and rapidly spreading disease. Even with the combined use of the four classic treatment modalities, surgery, radiation, chemotherapy and immunotherapy--little has been changed to alter the grim prospect. The only methods capable of eradicating liver cancer at the present time are partial resection of the liver in the case where the malignancy is localized or complete extirpation of the malignant liver and a replacement by transplantation. In liver transplantation cases, the cost of the procedure is substantial, followed by a lifelong administration of anti-rejection drugs, and medical follow-up involving doctor visits, blood tests, and imaging studies. Patients with advanced liver diseases, and in particular, patients with viral hepatitis B and C are known to be at a high risk of developing liver cancer. In the United States, there are 70,000 new hepatitis B cases and more than 250,000 newly diagnosed hepatitis C cases each year. Around the world and especially in Southeast Asia and China, Hepatitis B and C are at epidemic proportion without a cure in sight. The case is particularly serious as the Hepatitis virus can be transmitted during delivery to the newborn baby. This was demonstrated in recent studies from Taiwan in which 40% of babies born to Hepatitis B or C carrier mothers

were found to be positive for the same, a few days after delivery or a month later. In the same token hepatocellular carcinoma is at epidemic proportions in this region and represents a major public health issue for these countries. Web site: http://appft1.uspto.gov/netahtml/PTO/search-bool.html •
Prophylactic and therapeutic use of oltipraz as an antifibrotic and anticirrhotic agent in the liver and pharmaceutical composition containing oltipraz Inventor(s): Kang, Keon-Wok; (Seoul, KR), Kim, Sang-Geon; (Seoul, KR) Correspondence: Cantor Colburn, Llp; 55 Griffin Road South; Bloomfield; CT; 06002 Patent Application Number: 20030191137 Date filed: October 2, 2002 Abstract: The present invention provides a prophylactic and therapeutic use of 5-(2pyrazinyl)-4-methyl-1,2-dithiol-3-thione (oltipraz) as an antifibrotic and anticirrhotic agent in the liver and a pharmaceutical composition containing oltipraz for treating and preventing hepatic fibrosis and cirrhosis.Oltipraz of the invention can be used as a medicine optionally with other drugs for treating and preventing hepatic fibrosis and cirrhosis and shows an inhibiting effect of hepatic fibrosis at a relatively low dosage. Formulations using an optimal dose of oltipraz, which is provided by the invention, have a surprisingly good effect on the treatment and prevention of hepatic fibrosis and cirrhosis and are safe drugs that have a low toxicity on the human body. Excerpt(s): The present invention relates to a prophylactic and therapeutic use of 5-(2pyrazinyl)-4-methyl-1,2-dithiol-3-thione (oltipraz) as an antifibrotic and anticirrhotic agent in the liver and to a pharmaceutical composition comprising oltipraz as an active ingredient. The liver plays a key role in the metabolism of xenobiotics and in the metabolism of endogenous substances and is an important organ with consistent enzymatic reactions and energy metabolism. Among the many chronic diseases in Korea, hepatitis, cirrhosis, and liver cancer are the most widespread and life threatening next to cardiovascular diseases. As Korea has a relatively large population of drinkers of alcoholic beverages when compared to developed countries, and as liver damage due to binge drinking is fairly high, a lot of attention has been given to the treatment of liver diseases. Often chronic liver damage resulting from viral infection or alcohol consumption causes cirrhosis or liver cancer. In consideration of the physiological characteristics and importance of the liver, and in view of the importance of treating and preventing liver disease, demand is high for the ultimate development of therapeutic and preventive drugs against liver damage. Various substances, including several synthetic compounds and galenical preparations, show hepatoprotective functions both in vitro and in vivo. Although it has been known that silymarin and betaine have liver protective effects as a result of the action mechanism of cytokine inhibition and an increase in the level of glutathione, a curative effect would be hard to expect because of its low effectiveness. Because no appropriate curative agents against liver disease are currently available, said agents are frequently used for clinical trials. Malotilate and its derivatives, the indication of which is the treatment of liver fibrosis, protect the liver from toxic chemicals and the possible action mechanism includes the induction of phase II conjugating enzymes and the inhibition of cytochrome P450s. However, the compounds non-selectively inhibit several cytochrome P450s and show only preventive effects. Web site: http://appft1.uspto.gov/netahtml/PTO/search-bool.html

Dawes; Myers, Dawes & Andras Llp; Ste 1150; 19900 Macarthur Blvd; Irvine; CA; 92612; US Patent Application Number: 20030116705 Date filed: October 30, 2002 Abstract: A high-pressure hollow cathode ionizer is combined with an ion-mobilityspectrometer (IMS) for the detection of trace amounts of organic compounds in gas. The ionizer uses H.sub.30+, ions which do not react with air to ionize the organic compounds and the organic compounds are soft ionized. The ionized organic compounds are detected in the IMS at levels of parts per billion and identified using calibrated reference tables. Applications include but are not limited to the fields of: (1) medicine as a breath analyzer for detection of lung cancer, diabetes, liver cirrhosis, (2) law enforcement in drug interdiction and explosives detection, (3) food monitoring and control, (4) environmental monitoring and (5) space applications Excerpt(s): The present application is related to U.S. Provisional Patent Application serial No. 60/334,437, filed on Nov. 30, 2001, which is incorporated herein by reference and to which priority is claimed pursuant to 35 USC 119. The invention relates to the field of ionizers combined with ion-mobility spectrometers (IMS) for the detection of trace amounts of organic compounds in gas and methods of using the same. Miniature mass spectrometry is a powerful in-situ tool for identifying a wide variety of chemical compounds. For applications that cover many disciplines such as planetary exploration, residual gas analysis, and environmental applications, there is a need for an in-situ analytical separation device or chemical sensor which is rugged, light weight, low power, small, fast, and requires minute quantities of sample for analysis. These requirements are also applicable for the detection of certain organics in the medical sciences (analyzing human breath to detect compounds associated with certain deadly diseases such as lung cancer and cirrhosis of the liver), for a chemical sensor for use on the battlefield (chemical warfare agents), law enforcement (drug interdiction and explosives detection), and food monitoring and control.

Recombinant adenoviral vectors and their utility in the treatment of various types of fibrosis: hepatic, renal, pulmonary, as well as hypertrophic scars Inventor(s): Aguilar Cordova, Estuardo; (Col. Prado Coapa, MX), Armendariz Borunda, Juan; (Prado Coapa, MX) Correspondence: Pennie & Edmonds Llp; 1667 K Street NW; Suite 1000; Washington; DC; 20006 Patent Application Number: 20030003077 Date filed: March 18, 2002 Abstract: The use of gene therapy for the treatment of different kinds of fibrosis in human beings is disclosed. The purpose is the use of "therapeutic2 genes specifically directed to target organs to revert and/or prevent the development of the fibrosis process.The potential application of gene therapy to patients with fibrosis and/or
192 Cirrhosis
cirrhosis will depend to a large extent on the successful delivery of genes which encode for therapeutic proteins to livers with severe fibrosis and that these genes which encode for proteins human MMP-8 active and latent, MMP-1, MMP-2, MMP-9 and MMP-13; human uPA wild type and/or modified (or its truncated version), the truncated receptor for TGF-.beta. type II and Smad-7 can be directed by adenovirus and/or other recombinant vectors that cannot transduce (infect) others organs. The recombinant adenoviruses (AdR) are vectors highly efficient for the transduction of therapeutic genes to diverse target cells. We have proved that they can carry genes to cirrhotic livers.The delivery of therapeutic genes through such adenoviral vectors and other recombinant vectors could also be performed using cationic and anionic liposomes (DOTMA).Therefore, we propose the use of this patent to be applied in the same manner to:Renal fibrosisPulmonary fibrosisHypertrophic and keloid scars (skin fibrosis), andOther kinds of fibrosis. Excerpt(s): The present invention relates to the creation of RECOMBINANT ADENOVIRAL vectors bearing exogenous genes that encode for therapeutic proteins useful in the treatment of HEPATIC cirrhosis and generalized FIBROSIS, such as renal FIBROSIS, pulmonary FIBROSIS, HYPERTROPHIC scars and keloid of the skin, and/or in other target organs susceptible to suffer from it. It also relates to a mechanism of tissue-specific recognition of the affected cells by means of delivery of therapeutic genes to cirrhotic organs. Moreover, the invention provides an effective way for the treatment of fibrosis through the employment of recombinant adenoviral vectors which are claimed here, as well as the process to prepare these vectors, the pharmaceutical composition that contains them, and their therapeutic uses in the treatment of several fibrosis, which has great commercial expectancy in the pharmaceutical industry and also presents an important alternative as gene therapy for the treatment of chronicdegenerative diseases characterized by fibrosis, with great therapeutic application in the field of Medicine. Hepatic cirrhosis is a disease resulting from hepatic chronic damage. Damage might be toxic (chronic ingestion of alcohol), infectious (viral hepatitis, mainly by hepatitis B and/or C virus), immunological, (primary biliary cirrhosis), by biliary obstruction, (secondary biliary cirrhosis), metabolic (Wilson's disease). All forms of cirrhosis have characteristics in common: synthesis and excessive deposition of proteins of extracellular matrix (ECM), mainly collagen I and to a lesser extent collagens IV and III), and consequently the formation of nodules of hepatocytes, abnormal vascularization and portal hypertension (Antoni P P, Ishak K G, Nayak Nc, Poulsen H E, Sheuer P J, Sobin L H. These physiopathological processes lead to an alteration in the blood supply and in consequence in the nutrition of hepatic cells. Regardless of the ethiological agent and morphologic differences, all forms of cirrhosis have as a common end, hepatic failure causing the patient's death.

Treatment of acute and chronic liver disease Inventor(s): Grofte, Thorbjorn; (Viby J., DK), Vilstrup, Hendrik; (Risskov, DK) Correspondence: Browdy And Neimark, P.L.L.C.; 624 Ninth Street, N.W.; Washington; DC; 20001; US Patent Application Number: 20020028764 Date filed: August 14, 2001 Abstract: The present invention relates to IGF-1 treatment of an individual, such as e.g. a human being, suffering from an acute or chronic liver disease including hepatic cirrhosis. Acute and chronic liver disease according to the invention are characterized by low circulating IGF-1 and IGFBP3 levels. According to one preferred embodiment of the present invention, IGF-1 is administrered to a human being subcutaneously, preferably in the thigh or the abdominal skin, and preferably in two daily doses of about 50 microgram/kg twice a day. The present invention demonstrates that this dosis regime is able to restore normal IGF-1 levels in patients with liver cirrhosis, and the dose is well-tolerated by the patients. Excerpt(s): The invention relates to a method for treatment of acute and chronic liver disease in an individual. The treatment involves administration of insulin growth-like factor 1 (IGF-1) to an individual in need thereof. The liver disease may occur in combination with other diseases such as e.g. diabetes mellitus. Growth factors are growth promoting peptides that stimulate a wide variety of biological responses in a defined population of target cells. A variety of growth factors have been identified, including transforming growth factor beta (TGF-.beta.), epidermal growth factor (EGF),
194 Cirrhosis
platelet-derived growth factor (PDGF), fibroblast growth factor (FGF), and insulin-like growth factor 1 (IGF-1). IGF-1 is a naturally occurring growth promoting peptide and shares considerable structural and functional homology with insulin and is synthesized in the liver. It consist of 70 amino acids in a single poly-peptide chain with homology to pro-insulin and has a molecular weight of approximately 7.5 kilodaltons (kD).

Treatment with small peptides to effect antifibrotic activity Inventor(s): Clagett, James; (Snohomish, WA) Correspondence: Edwards & Angell, Llp; P.O. Box 9169; Boston; MA; 02209; US Patent Application Number: 20020072499 Date filed: September 21, 2001 Abstract: Methods for treating treating fibrosis in a mammal are described. An antifibrotic effective amount of a peptide having the formula f-Met-Leu-X where X is selected from the group consisting of Tyr, Tyr-Phe, Phe-Phe and Phe-Tyr is administered to the mammal. The fibrosis may be due to pathological changes resulting, e.g., from pulmonary fibrosis, atherosclerosis, cirrhosis, glomerulosclerosis, chronic pancreatitus, coronary artery disease (such as caused by infection by bacterium Chlamydia pneumoniae), trauma or surgical procedures. Examples of surgical procedures that cause fibrosis are post-operative fibrosis peri-neurally in the dura or nerve roots following spinal surgery, tenolysis of injured or repaired tendons with adhesions, neurolysis of damaged or repaired peripheral nerves with adhesions, postoperative adhesions from gynecologic and abdominal surgeries, reparative surgery of the vas deferens or fallopian tubes for reversal of male or female sterilization, and surgical repair of other tubular structures such as urethra, intestine or esophagus. Excerpt(s): This invention claims priority of provisional application Ser. No. 60/125,514 filed Mar. 22, 1999 which is a Continuation of PCT/US00/07411 filed Mar. 20, 2000. This invention relates to methods for treating mammals with small peptides to effect antifibrotic activity and thereby inhibit, prevent or even reverse fibrolysis in the mammal. More particularly, such treatment of mammals exhibiting fibrous lesions in arterial or airway lumens provides lumen remodeling as demonstrated by reduction in fibrosis. Endothelial dysfunction that results from the injury leads to compensatory responses that alter the normal homeostatic properties of the endothelium. Thus, the different forms of injury increase the adhesiveness of the endothelium with respect to leukocytes or platelets, as well as its permeability. The injury also induces the endothelium to have procoagulant instead of anticoagulant properties and to form vasoactive molecules, cytokines, and growth factors.

Summary: This monograph reprints papers from a conference held in November 1997 in Chicago, Illinois, on the clinical features (symptoms), pathogenesis, and treatment of primary biliary cirrhosis (PBC). PBC is generally considered to be an autoimmune disease and one that occurs in patients who are genetically predisposed to the disease. The part played by mitochondrial antibodies (AMA) in pathogenesis of PBC remains controversial. Alternatively, the disease may have an infectious etiology (cause). Therapy can be directed against any of these injurious processes. Drug therapy, notably combinations of drugs, can be used. Fibrosis (scarring) of the bile ducts occurs in PBC
198 Cirrhosis
and is responsible for the end picture of cirrhosis (liver scarring). Complications such as ascites (fluid accumulation) and portal hypertension (high blood pressure) need to be treated; other complications can include bone thinning and pruritus (itching). Liver (hepatic) transplantation performed before the terminal stages of PBC offers a five year survival exceeding 85 percent. There is evidence of recurrence in the graft. The monograph includes 20 chapters covering the natural history and demography of PBC, the immune basis for PBC, isolation and cloning of antimitochondrial antibodies, determining pathogenesis, molecular considerations of PBC, animal models of PBC, fibrogenesis in PBC, natural history models, portal hypertension in patients with PBC, osteoporosis, managing fatigue in the patients with PBC, pruritus associated with cholestasis (suppression of the flow of bile), immunosuppressant agents, methotrexate and colchicine in the treatment of PBC, corticosteroids in PBC, ursodeoxycholic acid treatment of PBC, ursodiol and combination therapy, transplantation, and new clinical trials in PBC. Each chapter concludes with references and a subject index concludes the monograph.

[email protected]. Website: www.blackwell-science.com. PRICE: $275.00. ISBN: 0632055421. Summary: Cirrhosis (liver scarring) is an end stage of chronic diffuse liver disease. Cirrhosis is characterized by alteration of the normal liver architecture into structurally abnormal nodules of liver cells, surrounded by fibrosis (scar tissue). This chapter on cirrhosis is from a textbook that familiarizes the reader with various imaging modalities, the information they provide, and the merits of each, in order to facilitate the combined use of different imaging techniques in the diagnosis and management of hepatobiliary (liver and bile tract) diseases. Diseases that cause cirrhosis include alcoholic liver disease, chronic viral hepatitis, biliary obstruction, heart failure, metabolic disorders such as copper overload (Wilson's disease), and many others, but alcohol and hepatitis virus are by far the most common etiology. Clinical manifestations including wasting, ascites (fluid accumulation) and edema, splenomegaly (enlarged spleen), esophageal varices (enlarged veins or arteries in the esophagus), and encephalopathy (involvement of the brain tissue). The disease is progressive if it in not treated or if the offending agent

is not removed, and for advanced cirrhosis, transplantation is the only cure. Most patients with uncomplicated cirrhosis die of variceal bleeding or hepatic (liver) failure. The author discusses epidemiology, pathophysiology, viral cirrhosis, clinical features, ascites and hepatic lymph, hepatic hydrothorax, portal-systemic encephalopathy, imaging features in cirrhosis, prognosis, and less common types of cirrhosis. 51 figures. 64 references. •

Summary: During the natural course of cirrhosis (scarring of the liver), a progressive impairment in kidney function occurs and the kidneys are no longer able to maintain the extracellular fluid volume within normal limits. As the disease progresses, a vasoconstriction of the renal circulation usually develops, which causes renal hypoperfusion and reduced glomerular filtration rate (GFR) and, eventually, renal failure (the so-called hepatorenal syndrome). This chapter on clinical disorders of renal (kidney) function in cirrhosis with ascites is from a textbook on ascites and renal dysfunction in liver disease. The authors describe the functional kidney abnormalities of cirrhosis. The authors emphasize the description of clinical aspects of these abnormalities. A general description of the pathogenetic factors contributing to kidney dysfunction is also included. Topics include sodium (salt) retention, water retention, and renal vasoconstriction and hepatorenal syndrome. The last section of the chapter describes other less common abnormalities of kidney function that may also be found in cirrhosis, including acute tubular necrosis (ATN), glomerular abnormalities, renal tubular acidosis (RTA), and drug-induced kidney failure. 8 figures. 4 tables. 187 references.

Summary: Primary biliary cirrhosis (PBC) is an inflammatory disease of the interlobular and septal bile ducts of the liver; the disease is thought to be immune-mediated. Granulomatous destruction of these bile ducts leads to duct deficiency and hence, persistent cholestasis (stoppage of the flow of bile). Progressive fibrosis and eventual cirrhosis develop and liver failure is a terminal event unless intervention with a liver transplant occurs. This chapter on the diagnosis and treatment of PBC 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 author of this chapter notes that PBC may be diagnosed in several situations. Most commonly (60 percent of the time), PBC is

diagnosed in a patient without symptoms, but with anicteric cholestatic biochemical tests, with a positive serological test for AMA (antimitochondrial antibodies), and with a diagnostic or confirmatory biopsy. Symptoms typical of PBC, such as fatigue, do not correlate with the severity of disease. However, the degree of hyperbilirubinemia has been shown to correlate extremely well with survival. Treatment with ursodeoxycholic acid (UDCA) is not curative. It may delay the progression of disease in some patients, but the evidence for this benefit is not clear. Several small trials of UDCA in combination with methotrexate, colchicine, and prednisolone have been conducted, but no study has been large enough to adequately assess the effectiveness of these drugs. Prognostic research indicates that liver transplantation leads to a marked survival benefit in patients with PBC. Currently, transplantation remains the only curative therapy for this disease. 1 table. 91 references. •

Summary: This chapter on hepatic cirrhosis (scarring of the liver) is from a textbook that presents a comprehensive and up-to-date account of diseases of the liver and biliary system. Cirrhosis is defined anatomically as a diffuse process with fibrosis and nodule formation. The chapter covers classification of cirrhosis, clinical cirrhosis, compensated cirrhosis, decompensated cirrhosis, prognosis, and treatment strategies. In cirrhosis, directed biopsies, using ultrasound or CT and a Trucut needle, are particularly helpful in obtaining adequate samples and avoiding other viscera, especially the gallbladder. The prognosis is determined by the extent of hepatocellular failure. Jaundice, spontaneous bruising, and ascites resistant to treatment are grave signs. Treatment options include nutrition, anti-fibrotic drugs, and surgery, although the latter is high risk and carries a high mortality in patients with cirrhosis. 14 figures. 4 tables. 84 references.

hepatitis virus, noting that all forms cause liver inflammation and cirrhosis and can cause symptoms like the flu, dark urine, or jaundice (yellowing of the skin). The narrators review the way each type is transmitted, the symptoms, the treatment and side effects, the prognostic factors, the availability of immunization, and the risk factors. The program goes into more depth on hepatitis A, interviewing patients and health care providers. Topics discussed are risk groups, including children in day care and people living in institutions or in crowded housing units; transmission; the geography of recent U.S. outbreaks; the symptoms of the disease; and treatment options, which are available only for the symptoms, since there is no treatment against the virus itself. The program notes that about 1 percent of people with hepatitis A develop fulminant hepatitis, which may need to be treated with liver transplantation. Another section reminds viewers of the risks of international travel and the importance of pretravel immunization. The program concludes with information about the American Liver Foundation (888-4437222) and a brief interview with Thelma King Theil, the chair of the Hepatitis Foundation International. •

Summary: This videotape offers a segment of ABC's Nightline program that explores the epidemic of hepatitis C virus (HCV) infection in the United States. In this program, ABC News anchor Forrest Sawyer investigates the virus with Dr. Miriam Alter, epidemiologist at the Centers for Disease Control and Prevention; Dr. Jerome Groopman, professor at Harvard Medical School; and Andi Thomas, founder of the advocacy group Hep-C ALERT. Together they examine topics including risk factors associated with the disease, improvements in blood screening, the results of targeted looks back at past blood recipients, and the need for additional funding to increase research. Hepatitis C is characterized as a definite health epidemic: 15 percent of the people who get infected successfully fight it off; in 80 percent of those infected, the disease becomes chronic; and in 5 percent of those infected, HCV results in liver cirrhosis (scar tissue), which can then lead to cancer and death. It is virtually impossible to predict who will be in which category. The disease is spread predominantly through needle sharing, sexual contact, and blood transfusions occurring prior to the 1990's. The disease has been called the silent epidemic because it was only identified 10 years ago and the infection remains symptomless for decades. The three panelists interviewed share their information and differences of opinions on the wisdom of getting tested for HCV, the magnitude of the public health problem of the disease, the need for targeted

PRICE: $10.00; plus shipping and handling. Summary: This videotape program reviews the physiology of the liver, and describes different types of liver disease, focusing on hepatitis. Narrated by Debbie Delgado-Vega, a liver transplant recipient and advocate and educator in the field, the program first summarizes the functions of the liver. The liver stores vitamins and minerals, makes bsoleilwelile to help digestion, detoxifies chemicals, stores energy, removes poisons and pollutants that may be ingested from the air, makes clotting factors, and defends against germs that cause disease. The program then lists the types of liver disease, including liver disorders in children, alcohol related liver disease, liver cancer, cirrhosis (scarring), and viral hepatitis (inflammation of the liver due to viral infection). The program discusses hepatitis in depth, explaining the differences between acute disease (less than 6 months in duration) and chronic disease; the numbers of people in the United States with hepatitis B (1.2 million) and hepatitis C (4.8 million); the complications of chronic hepatitis that can lead to cirrhosis (inflammation, scarring and nodules); symptoms, notably fatigue; how hepatitis B and C are transmitted in blood and other body fluids; other risk factors, including the use of intranasal cocaine, intravenous drugs, tattoos or body piercing, pre 1992 blood transfusion, unprotected sex, and having served time in jail; treatment options, including interferons and ribavirin; and why it is important to get tested and treated, even if there are no apparent symptoms. The narrator stresses that more Latinos die from liver disease than any other minority group and chronic liver disease is the third leading cause of death among Latinos. The conclusion of the program shows clips and materials from educational programs and public health and advocacy activities conducted by LOLA (Latino Organization for Liver Awareness). The program is narrated in English, with some clips at the end in Spanish.

Summary: This videotape program, narrated by Sandra Brandley, the Executive Director of the Alpha 1 National Association, reminds physicians of the symptoms and differential diagnosis of alpha 1 antitrypsin deficiency (A1AD or Alpha 1). The program features Dr. James Stoller, who describes the typical underdiagnosis of A1AD which is typical: the mean time until diagnosis is 7 years (from onset of symptoms) and the mean number of doctors consulted before diagnosis is 3.5. Alpha 1 is a relatively common genetic disorder that affects infants, children, and adults. It is the most common metabolic disorder that causes liver disease in infants and children; the disorder also causes cirrhosis and cancer of the liver in adults. Symptoms of A1AD deficiency in children include prolonged obstructive jaundice, low birth weight, mildly elevated liver enzymes, cholestasis, enlarged liver, abnormal bleeding, feeding difficulties, poor growth (or failure to thrive), and ascites (abnormal accumulation of fluids). In adults, the spectrum of liver disease associated with A1AD deficiency varies from mild to severe. Symptoms include chronic active hepatitis, cryptogenic cirrhosis (liver scarring of unknown cause), portal hypertension (high blood pressure in the portal vein of the liver), and hepatocellular carcinoma (liver cancer). A rare but telling symptom is panniculitis, a chronic inflammation of subcutaneous fat featuring ulcerated skin lesions on the torso. Dr. Stoller reminds viewers of the indications for A1AD screening: premature onset of moderate to severe chronic obstructive pulmonary disease (COPD) before age 50; predominant basilar emphysema; chronic bronchitis with airflow obstruction in a nonsmoker; bronchiectasis (irreversible dilation and destruction of the bronchial walls) without clear risk factors; development of unremitting asthma; family history of A1AD; cirrhosis without apparent risk factors; and family history of panniculitis. The program includes a chart of laboratory values and the risk of development of A1AD, and a series of interviews with patients about the interplay of early diagnosis and good quality of life. The program concludes with the contact information for the Alpha 1 National Association (800-521-3025). •

PRICE: $17.95 for members; $25.00 for nonmembers, plus shipping and handling. Summary: Viral hepatitis remains the most common cause of liver disease worldwide and infection with the hepatitis C virus (HCV) has become a serious health problem in the United States. This continuing education program assists family physicians in this new challenge of the identification and diagnosis of patients at greatest risk of HCV infection. While there is, as yet, no known cure for HCV, early medical intervention and lifestyle changes can significantly improve the prognosis. Infection with HCV can lead to chronic hepatitis, cirrhosis (liver scarring), and hepatocellular carcinoma (HCC, liver cancer). Unlike hepatitis A and B, there is no vaccination available to prevent hepatitis C, nor are there any preexposure or postexposure prophylaxis (prevention) options. This program reviews the epidemiology of HCV, identification of patients at risk, diagnosis, HCV related liver disease, and management approaches, including interferon monotherapy, combination therapy, side effects, contraindications, and ongoing medical monitoring. The program includes a video tape and a study guide; the latter includes references and a patient education handout, as well as a posttest with which viewers can qualify for continuing education credit. 6 figures. 13 tables. 31 references.

212 Cirrhosis
Summary: This sound recording covers a workshop on fear of the unknown, especially as it relates to Acquired immunodeficiency syndrome (AIDS). The moderator opens the session with a discussion of Hepatitis B. He says that 25,000 cases are reported to the Centers for Disease Control and Prevention (CDC) each year, primarily among young adults, but it is estimated that 300,000 persons become infected each year. Approximately 4,000 deaths each year result from cirrhosis of the liver following Hepatitis B infection, and 800 deaths each year from liver cancer. He says that Hepatitis B among health-care workers is decreasing since recombinant vaccines were developed, but the infection among Intravenous drug users (IVDU's) continues to rise. Next, Dr. Hassib Aoun, a former holder of a fellowship in cardiology at Johns Hopkins Hospital, describes his experiences following his infection with Human immunodeficiency virus (HIV) after a laboratory accident in 1983. A capillary tube of blood that he was planning to test shattered and cut his finger. Three years later, he developed AIDS. Although the original accident was documented, and the patient's blood was later tested for AIDS, (there were no antibody tests in 1983) the hospital accepted no responsibility for his illness and provided no compensation or insurance coverage. He says he still believes that health-care workers should never deny care to AIDS patients, but if they are expected to risk their lives providing this care, they should be protected economically with appropriate insurance. Dr. Jeff Hackman, Assistant Professor of Psychiatry and Behavioral Medicine at George Washington University Medical Center, then discusses a project to train health-care workers in the medical and mental health aspects of AIDS. A battery of attitude questionnaires given to second-year medical students revealed that 75 per cent were worried about contracting AIDS, and 80 per cent felt that in the future, AIDS would prove to be more infectious than it is considered today. Fifty percent of the medical students believed that they could contract AIDS from the routine care of an AIDS patient. They also said that their families were more frightened and less supportive of AIDS patients than the medical students themselves.

Search Engines Medical news is also available in the news sections of commercial Internet search engines. See the health news page at Yahoo (http://dir.yahoo.com/Health/News_and_Media/), or you can use this Web site’s general news search page at http://news.yahoo.com/. Type in “cirrhosis” (or synonyms). If you know the name of a company that is relevant to cirrhosis, you can go to any stock trading Web site (such as http://www.etrade.com/) and search for the company name there. News items across various news sources are reported on indicated hyperlinks. Google offers a similar service at http://news.google.com/. BBC Covering news from a more European perspective, the British Broadcasting Corporation (BBC) allows the public free access to their news archive located at http://www.bbc.co.uk/. Search by “cirrhosis” (or synonyms).
Newsletter Articles Use the Combined Health Information Database, and limit your search criteria to “newsletter articles.” Again, you will need to use the “Detailed Search” option. Go directly to the following hyperlink: http://chid.nih.gov/detail/detail.html. Go to the bottom of the search page where “You may refine your search by.” Select the dates and language that you prefer. For the format option, select “Newsletter Article.” Type “cirrhosis” (or synonyms) into the “For these words:” box. You should check back periodically with this database as it is updated every three months. The following is a typical result when searching for newsletter articles on cirrhosis: •
More Iron Overload Screening Recommended Source: Tufts University Health and Nutrition Letter. 18(11):7. January 2001.
218 Cirrhosis
Contact: 10 High Street, Suite 706, Boston, MA 02110.
[email protected]. www.healthletter.tufts.edu. Summary: Iron overload, or hemochromatosis, is the most common genetic disorder in the United States, affecting about 5 people per 1,000. Hemochromatosis affects primarily Caucasians of northern European descent. Researchers at the University of Utah School of Medicine say that not enough men and women are screened for the disorder. Complications arise because the body absorbs too much iron from foods due to defective metabolism. The excess iron deposits itself in body tissues, causing everything from cirrhosis of the liver to arthritis to diabetes to congestive heart failure. Once the disorder is diagnosed, people have to go for bloodletting a few times a year in order to avoid the complications because much of the excess iron is stored in the red blood cells. The University of Utah research team believes that all Caucasians should undergo screening at least once in young adulthood. Screening involves a blood test that measures transferrin saturation, which is a marker for iron status. •
Sjogren's Syndrome and the Gastrointestinal Tract Source: Moisture Seekers Newsletter. 17(2): 1, 4-5. March 1999. Contact: Available from Sjogren's Syndrome Foundation, Inc. 8120 Woodmont Avenue, Suite 530, Bethesda, MD 20814-1437. (301) 718-0300 or (800) 475-6473. Fax (301) 718-0322. Website: www.sjogrens.org. Summary: This article on Sjogren's syndrome (SS) and the gastrointestinal tract is from a patient education newsletter for people with SS. The author outlines the areas where the gastroenterologist may play a role in caring for the person with SS, such as dealing with swallowing difficulties, dyspepsia (indigestion), diarrhea, and jaundice (usually due to primary biliary cirrhosis, or scarring). Difficulty in swallowing is usually due to the lack of saliva associated with SS, but occasionally it may be due to a blockage (postcricoid web) or a weakness of the muscle contractions involved in swallowing. In addition, those patients with SS are vulnerable to acid reflux, which causes heartburn symptoms. Children with SS are prone to achalasia, a type of muscle problem involving the lower esophageal sphincter. Dyspepsia (indigestion) is relatively common in patients with SS, as is inflammation of the stomach (gastritis). The author briefly discusses the role of the bacterium Helicobacter pylori in gastritis. There are at least two diseases associated with SS and diarrhea: chronic pancreatitis and celiac disease (gluten intolerance). The author notes that the link between SS and gastroenterological conditions is often via abnormal autoantibodies.

Summary: This newsletter article provides health professionals with information on the adverse effects of methotrexate, which is one of the most effective drugs available for treating psoriasis. The main adverse effect is hepatoxicity, as confirmed by various studies. Patients who are alcoholic, obese, or diabetic are at greater risk of developing cirrhosis of the liver when treated with methotrexate. Other side effects include bone marrow suppression, gastrointestinal and pulmonary toxicity, phototoxicity, and malignancy. Methotrexate also poses risks for conception and pregnancy, with miscarriages and birth defects occurring if it is taken during pregnancy. In addition, it may temporarily affect male fertility. 10 tables.

[email protected]. Summary: When people learn they have hepatitis C, their initial reaction is often disbelief and confusion. Many of those carrying this silent and sometimes deadly bloodborne virus feel perfectly healthy and learn of their infection only after donating blood or having routine blood tests. This newsletter article reports on a recent effort by the Centers for Disease Control and Prevention (CDC) to improve people's awareness by launching a hepatitis C public information campaign. People who are not now infected with HCV are not likely to get it unless they use IV drugs. Improved blood screening has made the risk of contracting HCV from a transfusion exceedingly low. However, most people who have HCV don't realize they're carrying the virus, which can lurk in the liver for decades before symptoms appear. It is important for people to know they have HCV so they can avoid alcohol (which accelerates liver damage), undergo frequent blood tests to monitor their liver function, and consider treatments with antiviral drugs that can reduce or eliminate the virus in some people. The majority of carriers remain fairly healthy, but at least 20 to 30 percent eventually develop cirrhosis (scarring of the liver caused by prolonged inflammation). Several blood tests can determine if a person has been infected with HCV. The author describes these tests and then briefly outlines the treatment options for HCV. One sidebar offers the contact information (telephone numbers and websites) for three resource organizations. 2 references.
Academic Periodicals covering Cirrhosis Numerous periodicals are currently indexed within the National Library of Medicine’s PubMed database that are known to publish articles relating to cirrhosis.

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 cirrhosis. 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 cirrhosis. 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

Commercial Databases In addition to the medications listed in the USP above, a number of commercial sites are available by subscription to physicians and their institutions. Or, you may be able to access these sources from your local medical library.
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/.
Researching Medications
223
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 cirrhosis 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 “cirrhosis” (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 cirrhosis: •
Ursodiol (trade name: URSO) http://www.rarediseases.org/nord/search/nodd_full?code=256
•
Ursodiol (trade name: Actigall) http://www.rarediseases.org/nord/search/nodd_full?code=262
If you have any questions about a medical treatment, the FDA may have an office near you. Look for their number in the blue pages of the phone book. You can also contact the FDA through its toll-free number, 1-888-INFO-FDA (1-888-463-6332), or on the World Wide Web at www.fda.gov.

Hepatitis C Update: Recommendations from the NIH and CDC Source: JAAPA. Journal of the American Academy of Physician Assistants. 11(12): 35-37. December 1998. Contact: Available from Medical Economics. 5 Paragon Drive, Montvale, NJ 07645. (800) 432-4570. Fax (201) 573-4956. Summary: In March 1997, the National Institutes of Health (NIH) conducted a consensus development conference on the management of hepatitis C virus (HCV) infection. In July 1998, the Centers for Disease Control and Prevention (CDC) held a consultants meeting on HCV, from which it developed recommendations for the prevention and control of HCV infection and related chronic disease. This article reviews these two sets of recommendations, summarizing and comparing the guidelines in the areas of screening, counseling, monitoring, and treatment. The CDC recommends screening persons at low risk of HCV infection with the enzyme immunoassay (EIA) HCV antibody test, which has a sensitivity of greater than 97 percent. If indicated, the recombinant immunoblot assay is used as a confirmation test. The NIH, on the other hand, recommends measurement of HCV RNA with the polymerase chain reaction, if indicated, as a confirmatory test of a positive EIA. The CDC recommends that people who test positive for HCV should be counseled about being evaluated for their disease and possibly being treated. They should be instructed about reducing the risk of transmitting the virus to another person and refraining from donating blood or other body tissues. The CDC recommends vaccination against hepatitis A in a person who has chronic HCV infection; the NIH recommends vaccination against hepatitis A and B. Liver biopsy remains the gold standard for assessing disease activity, including progression to fibrosis and cirrhosis. Treatment is recommended when findings on liver biopsy include periportal or bridging fibrosis and a moderate degree of inflammation and necrosis. Patients who have had one or more episodes of decompensated cirrhosis (ascites, variceal bleedings, or encephalopathy) should be referred to a center that performs liver transplantation. 1 figure. 3 references.

Summary: In this article, the authors present the proceedings of two panels on chronic hepatitis of the World Congresses of Gastroenterology (WCPG) working party. The authors hope that the suggested terms, definitions, and codes can: be used by clinicians and laboratory physicians as they jointly care for patients; keep the language in hepatology contemporary; and help to create data that lend themselves to improved computerized coding and retrieval in the interest of patient service and research. After a discussion of background and objectives, the authors present definitions, synonyms, and clinical, laboratory, and histological findings for the following conditions: autoimmune hepatitis; chronic hepatitis B; chronic hepatitis D; chronic hepatitis C; chronic drug hepatitis; primary biliary cirrhosis; primary sclerosing cholangitis; Wilson's disease of the liver; and alpha-1-antitrypsin deficiency. One brief section discusses the grading and staging of chronic hepatitis. 2 tables. 28 references. •

[email protected]. 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.

Summary: This report is designed to bring clinicians, allied health care workers, and patients up to date on hepatitis C virus (HCV), including epidemiology, natural history, diagnosis, pathogenesis, and treatment. After an analysis of peer reviewed articles, over 40 researchers, clinicians, primary care physicians, government health administrators, industry representatives, and patients with viral hepatitis were interviewed for this report. Eleven chapters cover epidemiology, modes of transmission, and risk factors; pathogenesis, viral dynamics, and immunologic response; natural history, clinical manifestations, and prognostic indicators of disease progression and survival of HCV infection; diagnostic considerations; the use of interferon to treat HCV infection; the mechanism of HCV resistance to interferon; experimental treatments and new areas of research; hepatitis and HIV coinfection; current opinions and controversies in HCV infection; research and policy recommendations; and clinician's response. The natural history chapter reminds readers that not all patients with HCV inexorably deteriorate to end stage liver disease, liver transplantation, or death. The diagnosis of HCV is often complex with multiple tests and the confusion of liver biopsy evaluation. The role of HCV in response to HIV therapy is largely unknown. Approximately only half of HCV patients respond to current therapies, but the report considers whether perhaps only half may actually need therapy in the long term. Unfortunately, clinicians cannot determine which patients will progress to fibrosis and end stage liver disease and so most patients are treated, especially if they have some scarring without cirrhosis. Interferon remains the mainstay of therapy, with pegylated IFNs providing new advances. Each chapter includes illustrations and a list of references.

Coffee Break: Tutorials for Biologists21 Coffee Break is a general healthcare site that takes a scientific view of the news and covers recent breakthroughs in biology that may one day assist physicians in developing treatments. Here you will find a collection of short reports on recent biological discoveries. Each report incorporates interactive tutorials that demonstrate how bioinformatics tools are used as a part of the research process. Currently, all Coffee Breaks are written by NCBI staff.22 Each report is about 400 words and is usually based on a discovery reported in one or more articles from recently published, peer-reviewed literature.23 This site has new articles every few weeks, so it can be considered an online magazine of sorts. It is intended for general background information. You can access the Coffee Break Web site at the following hyperlink: http://www.ncbi.nlm.nih.gov/Coffeebreak/.
Other Commercial Databases In addition to resources maintained by official agencies, other databases exist that are commercial ventures addressing medical professionals. Here are some examples that may interest you: •

The Genome Database26 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. To access the GDB, simply go to the following hyperlink: http://www.gdb.org/. Search “All Biological Data” by “Keyword.” Type “cirrhosis” (or synonyms) into the search box, and review the results. If more than one word is used in the search box, then separate each one with the word “and” or “or” (using “or” might be useful when using synonyms).

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 cirrhosis 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 cirrhosis. 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 cirrhosis. 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 “cirrhosis”:

PRICE: Single copy free to patient. Summary: The liver weighs about three pounds and is the largest organ in the body. When chronic diseases cause the liver to become permanently injured and scarred, the condition is called cirrhosis. This brochure outlines cirrhosis, noting that the scar tissue that forms in cirrhosis harms the structure of the liver, blocking the flow of blood through the organ. The loss of normal liver tissue slows the processing of nutrients, hormones, drugs, and toxins by the liver. Also slowed is production of proteins and other substances made by the liver. The brochure reviews the major causes of cirrhosis, the symptoms of the condition, diagnostic tests used to confirm and monitor cirrhosis, treatment options, and complications of cirrhosis and how they are treated.

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 cirrhosis. 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.

Members discuss medical information, pain management, medications, and research; ask questions; and vent anger and fears. The PBCers was formed in 1996. Current membership is more than 2,400 worldwide.
Finding Associations There are several Internet directories that provide lists of medical associations with information on or resources relating to cirrhosis. By consulting all of associations listed in this chapter, you will have nearly exhausted all sources for patient associations concerned with cirrhosis. The National Health Information Center (NHIC) The National Health Information Center (NHIC) offers a free referral service to help people find organizations that provide information about cirrhosis. For more information, see the
246 Cirrhosis
NHIC’s Web site at http://www.health.gov/NHIC/ or contact an information specialist by calling 1-800-336-4797. Directory of Health Organizations The Directory of Health Organizations, provided by the National Library of Medicine Specialized Information Services, is a comprehensive source of information on associations. The Directory of Health Organizations database can be accessed via the Internet at http://www.sis.nlm.nih.gov/Dir/DirMain.html. It is composed of two parts: DIRLINE and Health Hotlines. The DIRLINE database comprises some 10,000 records of organizations, research centers, and government institutes and associations that primarily focus on health and biomedicine. To access DIRLINE directly, go to the following Web site: http://dirline.nlm.nih.gov/. Simply type in “cirrhosis” (or a synonym), and you will receive information on all relevant organizations listed in the database. Health Hotlines directs you to toll-free numbers to over 300 organizations. You can access this database directly at http://www.sis.nlm.nih.gov/hotlines/. On this page, you are given the option to search by keyword or by browsing the subject list. When you have received your search results, click on the name of the organization for its description and contact information. The Combined Health Information Database Another comprehensive source of information on healthcare associations is the Combined Health Information Database. Using the “Detailed Search” option, you will need to limit your search to “Organizations” and “cirrhosis”. Type the following hyperlink into your Web browser: http://chid.nih.gov/detail/detail.html. To find associations, use the drop boxes at the bottom of the search page where “You may refine your search by.” For publication date, select “All Years.” Then, select your preferred language and the format option “Organization Resource Sheet.” Type “cirrhosis” (or synonyms) into the “For these words:” box. You should check back periodically with this database since it is updated every three months. The National Organization for Rare Disorders, Inc. The National Organization for Rare Disorders, Inc. has prepared a Web site that provides, at no charge, lists of associations organized by health topic. You can access this database at the following Web site: http://www.rarediseases.org/search/orgsearch.html. Type “cirrhosis” (or a synonym) into the search box, and click “Submit Query.”

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.27
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

[NIH] 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
Dictionary 281
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.
