Active clinical trials for "Hepatitis A"

MaHeVi is a multicenter, cross-sectional, population-based study which will include 2500 adults in the health care centers / missions located on the 2 sides of the Maroni River. All major inhabitants of the river border between French Guiana and Suriname may participate, after an extensive communication campaign.The main objective is to estimate the prevalence and status of infection with hepatitis B (HBV), hepatitis C (HCV), D (VHD) and HIV in the general adult population of the Maroni River, border between French Guiana and Suriname. After signing the informed consent and pre-test counseling, capillary blood will be collected on blotting paper. Participants will be interviewed on infection risk factors. Positivity for HBsAg, total anti-HBcAb, anti-HCV Ab, total anti-HDV Ab(for HBsAg positive) and HIV p24 Ag or anti-HIV Ab (confirmed by molecular biology for hepatitis and Western Blot for HIV) will inform respectively on the HBV, HCV, HDV and HIV infection status.

The effective control of nucleos(t)ide analogues for patients infected with hepatitis B has significantly curbed the horizontal transmission of hepatitis B. However, the vertical transmission remains a serious threat to public health for directly increasing the burden of hepatitis B worldwide with the transmission rate up to 80 to 90% among high HBV DNA level if untreated. Currently, the effective prevention of mother-to-child transmission is credited to the implement of HBV vaccination and hepatitis B virus immunoglobin. To leave nobody behind, a growing body of evidence has been yielded to support the use of nucleos(t)ide analogues in the mothers during the late pregnancy. However, the clinical practice can be more complex. Therefore, investigators aim to assess the effectiveness of maternal antiviral therapy and different infants immunoprophylaxis strategy in the prevention of chronic hepatitis infection among children whose mothers were infected with chronic hepatitis B infection in the real world setting.

The investigators assessed non-organ-specific antibodies before and 24 weeks after the end of therapy with direct-acting antivirals, in order to better clarify the clinical relevance of these antibodies in terms of treatment response and prognostic value. To achieve this goal patients with hepatitis C virus related advanced liver disease, with detectable circulating autoantibodies on at least two determinations before treatment, were enrolled.

The project will evaluate cost and treatment outcomes of a simplified hepatitis C virus (HCV) testing, treatment and care model integrated with HIV testing and treatment among key affected populations including people who inject drugs (PWID) in Myanmar.

Primary objective: 1. To estimate the effectiveness of treatment with FDC of Zepatier with or without ribavirin in Israeli patients with CHC and advanced fibrosis in real life setting. Secondary objective: 1. To estimate the safety and tolerability of treatment with FDC of Zepatier with or without ribavirin in real life setting in Israeli patients with CHC and advanced disease. Hypotheses: Effectiveness and tolerability of treatment with FDC of Zepatier with or without ribavirin in Israeli patients with CHC and advanced fibrosis will be similar to that demonstrated in phase 3 clinical trials.

Progression of liver fibrosis in patients with hemoglobinopathies is strongly related to the severity of iron overload and the presence of chronic hepatitis C virus (HCV) infection. Effective iron chelation therapy and HCV infection eradication are efficacy to prevent liver complications. EASL and AASLD guidelines recommend interferon-free regimens for the treatment of HCV infection in patients with hemoglobinopathies. However, data regarding the use of direct-acting antiviral drugs (DAAs) in this patient population are very few This large, observational study evaluated the safety and efficacy of standard therapy with DAAs in a large Italian cohort of with hemoglobinopathies, chronic HCV infection and advanced liver fibrosis.

Post-marketing surveillance study to evaluate the real world safety and effectiveness of Maviret (Glecaprevir/Pibrentasvir) administered under a normal, routine treatment practice by Korean patients with Chronic Hepatitis C Genotypes 1 to 6

This study aims to evaluate the immunologic response to the two hepatitis B virus (HBV) vaccination booster strategies in previously vaccinated HIV-infected adults at Maharaj Nakorn Chiang Mai Hospital.

Background: Treatment of some diseases can suppress the immune system. This can cause other conditions to reactivate. Recent cases have shown that hepatitis B virus (HBV) reactivates in people who had already recovered from it during treatment for chronic hepatitis C (CHC). Their treatment was direct-acting antiviral (DAA) agents. Researchers want to see how common this reactivation is. They want to learn what the effects are. They will study data that have already been collected. Objectives: To study HBV reactivation in people with CHC and resolved HBV infection who are being treated with interferon-free DAA-based therapy. Eligibility: Data were collected from adults 18 and older in studies that were done in 2012 and 2016. Design: Researchers will screen the records from the previous studies. They will identify participants who had HBV infection before they got DAA-based treatment. Researchers will take data from those records. This will include data on: Age, sex, race, and ethnicity Treatment and disease status Lab results Researchers will test stored samples. They will test samples that were taken before, during, and after treatment. They will check if HBV was reactivated. They will also check if other clinical outcomes occurred.

The aim of this study was to evaluate the current prevalence and risk factors of hepatitis B virus (HBV) infection in a multi-ethnic neighbourhood situated in Middle Limburg, Belgium. Additionally, the investigators will determine linkage of care in hepatitis B surface antigen (HBsAg) positive subjects.
