The nonstructural 5A (NS5A) protein is a target for drug development against hepatitis C virus (HCV). Interestingly, the NS5A inhibitor daclatasvir (BMS-790052) caused a decrease in serum HCV RNA levels by about two orders of magnitude within 6 h of administration. However, NS5A has no known enzymatic functions, making it difficult to understand(More)
BACKGROUND AND AIMS Recent studies have shown an association between obstructive sleep apnea (OSA) and elevated liver enzymes in patients with nonalcoholic fatty liver disease (NAFLD). The aim of the current study was to compare biochemical and histologic findings in patients with NAFLD as a function of OSA status. METHODS Subjects consisted of 85(More)
BACKGROUND Interventions that minimize hepatic ischemia/reperfusion injury (IRI) can expand the donor organ pool. Thymoglobulin (TG) induction therapy has been shown to ameliorate delayed graft function and possibly decrease IRI in cadaver renal transplants recipients. This controlled randomized trial was designated to assess the ability of TG to protect(More)
Health-related stigma is a cause of stress, alienation and discrimination that can serve as a barrier to prevention and care for infectious diseases such as HIV. Hepatitis B virus (HBV)-related stigma is common in Asian immigrants, but has not been formally evaluated. The aim of this study was to develop and validate the first HBV stigma instrument and to(More)
BACKGROUND & AIMS Mild to moderate hepatic iron loading is common in patients with chronic hepatitis C. We sought to determine whether mutations in the hemochromatosis gene, HFE, are associated with iron overload and acceleration of disease progression in hepatitis C patients. METHODS A total of 316 patients with chronic hepatitis C were studied: 198(More)
CONTEXT Hepatocellular carcinoma (HCC) is recognized as a complication of cirrhosis related to nonalcoholic fatty liver disease (NAFLD). Diabetes and the metabolic syndrome are also associated with HCC. However, it is not clear whether NAFLD predisposes patients to HCC in the absence of cirrhosis. OBJECTIVE To seek evidence that HCC can develop in NAFLD(More)
GOALS The aim of this study is to evaluate the prevalence and the clinical and histologic correlates of autoantibodies in patients with nonalcoholic steatohepatitis (NASH). BACKGROUND Antinuclear antibodies (ANA) and anti-smooth muscle antibodies (ASMA) have been identified in patients with NASH. The significance of autoantibodies in NASH is uncertain. (More)
BACKGROUND & AIMS The pathogenesis of chronic hepatitis C is poorly understood. This study examines the ability of hepatitis C virus (HCV) to infect, replicate in, and produce progeny virus from perihepatic lymph nodes in vivo. METHODS Lymph node (LN) biopsy specimens were taken from 20 patients with HCV genotype 1 infection and end-stage liver disease(More)
Nonalcoholic fatty liver disease (NAFLD) is highly prevalent and can result in nonalcoholic steatohepatitis (NASH) and progressive liver disease including cirrhosis and hepatocellular carcinoma. A growing body of literature implicates the peroxisome proliferators-activated receptors (PPARs) in the pathogenesis and treatment of NAFLD. These nuclear hormone(More)
The association of human leukocyte antigen (HLA) genes with the outcome of hepatitis C virus (HCV) infection may be modified by ethnic and geographical differences. HLA-A, -C, -DRB1 and -DQB1 genotyping were performed in a Midwestern American cohort of 105 HCV infected subjects among which 49 cleared HCV infection and 56 had persistent viral infection. A(More)
