Prevalence of HCV in HIV-negative MSM
Hepatitis C Virus InfectionThis study measures the prevalence of undiagnosed hepatitis C virus (HCV) infection in HIV-negative men-who-have-sex-with-men (MSM) visiting the sexual health clinics of public health services (in dutch: gemeentelijke gezondheidsdienst, GGD), in order to evaluate if systematic screening for HCV of HIV-negative MSM attending sexual health clinics in the Netherlands is needed.
Autoantibodies and Direct-acting Antivirals
Viral Hepatitis CTherapy Adverse EffectThe 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.
Simplified Antiviral Treatment Strategy for Hepatitis C in Myanmar
Hepatitis CHepatitis B1 moreThe 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.
Real World Experience of Chronic Hepatitis C (CHC) Treatment in Israel
Hepatitis CPrimary 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.
Hepatitis C Virus Infection in Patients With Hemoglobinopathies
Hepatitis CChronic1 moreProgression 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.
Direct Acting Antiviral-Post Authorization Safety Study
Hepatitis CHepatocellular CarcinomaThis is an independent optional sub-study parallel to TARGET-HCC (NCT02954094). The purpose of Direct-Acting Antiviral-Post Authorization Safety Study (DAA-PASS) is to investigate the impact of exposure to direct-acting antivirals (DAAs) on early recurrence of hepatocellular carcinoma (HCC) in hepatitis C virus (HCV)-infected patients following successful HCC treatment interventions.

Hepatitis B Reactivation During Treatment With Direct-Acting Antiviral Agents for Chronic Hepatitis...
Hepatitis BBackground: 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.
APPROACH Study: Quality of Life and Outcomes Assessment in Participants With Chronic Hepatitis C...
Hepatitis CChronicThis multi-center, observational study will examine the clinical use and outcomes of pegylated interferon (PEG-IFN) alfa-2a and ribavirin combination (PEGASYS RBV) in participants with chronic hepatitis C (CHC). Study visits will be scheduled for baseline, 12, 24 and 48 weeks after baseline. An additional follow-up visit at week 72 will be required for participants with an HCV genotype other than 2 or 3. Quality of life data will be collected at baseline, and at each follow-up visit.
