Active clinical trials for "Hepatitis A"

The main objective of this study is to assess the interest (linkage to care) of the Cepheid GeneXpert HCV VL Fingerstick test in Brussels among drug users or former users in contact with the Réseau Hépatite C Bruxelles organization through different partners of this network.

The aim of our study is to validate the non-invasive model which was constructed by our previous study for evaluating liver fibrosis or cirrhosis caused by hepatitis B virus in mainland China and to find a therapeutic regimen to reverse liver fibrosis and cirrhosis.

The purpose of this open-label, non-randomized, single-arm, multicentre observational study is to investigate the influence of the cumulative dose (total administered dose/ planned dose) of ribavirin on the sustained virologic response (SVR) in participants who have been receiving combination therapy with pegylated interferon alfa-2a (Pegasys) and ribavirin (Copegus).

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.

The CTSI-PLACE Study is a study for men and women with HIV/hepatitis C co-infection or HIV only. The study looks at the impact of having hepatitis C virus in addition to HIV on risk for cardiovascular disease. Participants will undergo non-invasive assessment of cardiovascular disease risk through measurements of endothelial function and blood biomarkers at baseline and 1 year (or 4 weeks and 24 weeks after end of HCV treatment for those that undergo HCV treatment during study follow-up).

Hepatitis B virus (HBV) infection is a challenging health problem. According to the World Health Organization, an estimated 240 million individuals (3.7%) suffered from chronic HBV infection worldwide. After acute hepatitis B virus (HBV) infection, the disappearance of hepatitis B surface antigen (HBsAg) had generally been believed to signify viral elimination. However, it now becomes clear that those subjects may have occult HBV infection which is defined as the presence of HBV DNA in the liver in the absence of HBsAg in the serum. Occult HBV infection usually accompanies antibody against hepatitis B core antigen (anti-HBc) and/or antibody against HBsAg (anti-HBs), but some cases might not have these serological markers (seronegative occult HBV infection) .

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.

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.

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.

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.
