Active clinical trials for "Hepatitis A"

The investigators aim to determine the prevalence of hepatitis C in the adult children of female baby boomers. During the years baby boomers were becoming pregnant, hepatitis C testing was either not available or was not standard of care. Because of this, participants' children may be unaware of participants' risk of hepatitis C.

Objectives: The general objective of the present project is to gain a better understanding of disease outcome in cACLD patients treated with the new oral DAA. In particular, the project will focus on: - To evaluate the long term prognosis of patients with compensated advanced chronic liver disease (cACLD) who achieve sustained virological response (SVR) after the new oral direct-acting antiviral agents (DAA), and determine clinical and elastographic basal and follow-up parameters to identify low and high risk groups of developing liver-related decompensation. Methods: Prospective cohort study in patients with cACLD in whom basal and annual clinical features and liver stiffness measurements (LSM) will be performed, and survival free of liver-related events will be analyzed.

Hepatitis B virus (HBV) infection remains difficult to eradicate with about 240 million people living with HBV chronic infection. HBsAg clearance, correlated with a good clinical prognosis, is difficult to achieve even with antiviral treatments (3-14 %). HBV envelope proteins are essential for entry into hepatocyte and are targeted by the immune system. Molecular characteristics of HBV envelope proteins may favour better viral fitness at the entry step into hepatocytes and/or HBV escape from host immunity. Here we investigated whether variability of HBV envelope proteins can contribute to the differential responses to anti-HBV treatment in patients with HBsAg clearance or persistence.

Initially, HCV Informatics (C-IT) will be used to filter the EMR data of the one million people who receive care at Mount Sinai and identify candidates for HCV testing (baby boomers, patients with HIV infection) and candidates for HCV treatment (patients with positive test results for HCV RNA and no record of treatment).once treatment candidates have been identified through this proactive approach, their providers will be directly notified. HCV champions and patient navigators will be used to further lower barriers to the delivery of HCV care. They will be co-located at non-hepatology care sites and will help deliver open-label HCV treatment as part of standard medical care to 500 HIV/HCV co-infected patients and 200 patients with type 2 diabetes.

In this cohort study, patients with chronic hepatitis B who prior participated in TB1211IFN study and received at least 39 doses of peginterferon alfa will be enrolled. HBsAg/anti-HBs level, HBeAg/anti-HBe level, Serum HBV DNA load and alanine transaminase level will be test every year from the second year to the fifth year after the ending of peginterferon alfa treatment, and long-term benefit of interferon treatment will be evaluated.

This observational study will assess predictors of early on-treatment and sustained virological response in treatment-naïve patients with chronic hepatitis C initiated on treatment with Pegasys (peginterferon alfa-2a) or peginterferon alfa-2b and ribavirin. Data will be collected during the treatment period (24 or 48 weeks) and 12 and 24 weeks after the end of treatment. Target sample size is <2000.

The purpose of this study is to investigate the differences of genotypes of hepatitis B and hepatitis C in Taiwan.

Chronic hepatitis C (CHC) is among the commonest chronic infectious disease in Australia with >200,000 exposed persons. Amongst non-infectious chronic conditions- Type 2 diabetes, obesity and heart disease are extremely common. This study will examine the relationship between insulin resistance, fat deposition in the liver, muscle and abdomen, and liver injury due to CHC

This study has the aim of describing viral mutation profiles in patients diagnosed with chronic hepatitis B receiving antihepadnaviral therapy.

The response to vaccination for hepatitis is reduced in patients with HIV infection. The hypothesis of the study is that adjuvant interleukin-2 administered subcutaneously at the time of vaccination improves the response rate.
