Boceprevir-based triple therapy to rescue HCV genotype 1/HBV dually infected patients refractory to peginterferon plus ribavirin combination therapy in Taiwan.

BACKGROUND/PURPOSE: The role of directly-acting antivirals (DAA)-containing regimens in the treatment of patients dually-infected with hepatitis C virus (HCV) and hepatitis B virus (HBV) remains unclear. The pilot study aimed to explore the safety and efficacy of a protease inhibitor, boceprevir, in combination with peginterferon/ribavirin for HCV genotype 1 (HCV-1)/HBV dually-infected patients refractory to prior peginterferon/ribavirin. METHODS: Twelve peginterferon-experienced patients dually-infected with HCV-1/HBV were assigned to receive boceprevir 800 mg, twice a day, plus peginterferon-α 2b 1.5 µg/kg/week and ribavirin 800-1400 mg/day for 36 or 48 weeks. The primary endpoint was HCV sustained virological response (SVR, HCV RNA undetectable 24 weeks after end-of-treatment). RESULTS: Five patients terminated treatment early due to adverse events (one at week 4, one at week 46), virological failures (one non-response and one breakthrough), and patient request (n = 1). Eight patients achieved HCV SVR (66.7% in full-analysis set and 72.7% in modified intention-to-treat population). The HCV SVR rate was 71.4% (5/7) in prior relapsers, 60.0% (3/5) in prior null responder; 75% in non-cirrhotic and 50% in cirrhotic patients. All four patients of prior non-cirrhotic relapsers received 36-week regimen and achieved HCV SVR. There was no HBV-related hepatic flare. All patients experienced at least one adverse event. Two had serious adverse events. CONCLUSION: Boceprevir plus peginterferon/ribavirin is effective in the treatment of HCV-1/HBV dually infected patients' refractory to prior peginterferon/ribavirin combination therapy.

Health literacy and risk of viral hepatitis among Chinese school children.

INTRODUCTION: Poor literacy is associated with hepatitis morbidity and mortality. Adolescents are especially at risk of hepatitis C. This study investigated viral hepatitis literacy, risk, and influencing factors among Chinese middle and high school students. METHODOLOGY: A supervised self-administered survey was conducted with school children from six schools in Shantou, China. Data on demographics, health literacy, and risk of viral hepatitis were analyzed. RESULTS: A total of 1732 students (from three middle and three high schools) participated in the study. Their major information resources were the internet (39.5%, 685/1732), television (28.8%, 498/1732), family (27.7%, 479/1732), and school (21.2%, 368/1732). The mean literacy score on the manifestations and risk factors of hepatitis was 3.4 ± 2.2 and 4.0 ± 2.3 (out of 8), respectively. Multiple linear regression models showed being female and in high school, having parents with higher education levels, and school or clinicians as an information resource were independent positive predictors, whereas poor awareness of risk factors was a negative predictor for health literacy. CONCLUSIONS: We report the risk of hepatitis among Chinese middle and high school students due to limited literacy and poor attitudes towards health-risk behaviors. Health education in school is recommended for preventable health risks among Chinese adolescents.
