Direct-acting antiviral (DAA) therapy carries a potential risk of inducing hepatitis B virus (HBV) reactivation. However, the HBV kinetics during and after DAA therapy in patients co-infected with hepatitis C virus (HCV) and HBV remain unknown. We retrospectively evaluated the HBV kinetics during and after sofosbuvir/ribavirin therapy in four HBV inactive carriers co-infected with HCV. HCV was eradicated in all patients. Changes in HBV-DNA levels during treatment differed among patients. The hepatitis B surface antigen (HBsAg) levels uniformly decreased (mean -0.530 logIU/mL) by the end of treatment and returned to near the baseline in all patients. Sofosbuvir/ribavirin therapy thus demonstrated a suppressive effect on HBsAg.
