Popis: Introduction and Objectives: Some studies suggest chronic HCV infection diminishes responses to the anti-HBV vaccine. We evaluated the efficacy of double versus standard dose HBV vaccination among HCV patients without cirrhosis. Patients and Methods: 141 adults with untreated chronic HCV were randomized to HBV vaccination with double dose (40μg) or standard dose (20μg) at 0, 1 and 6 months; 70 healthy HCV-negative patients given standard dose served as controls. Vaccine response was defined by anti-HBs ≥10 mIU/mL. Results: 128 patients (60 double, 68 standard doses) completed the study. Patients were of median age 52 years, 61% female, 60% fibrosis
