Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
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.
