Abstract
Background and aims: Seroclearance or seroconversion of hepatitis B surface antigen (HBsAg) is generally considered as the clinical endpoint. The purpose of the present meta-analysis was to evaluate pegylated interferon alpha (PEG-IFNα) with or without lamivudine (LAM) or adefovir (ADV) combination treatment in HBsAg seroclearance or seroconversion with CHB. Methods: Randomized controlled trials of adults with CHB prior to May 30th 2015, with 48-52 weeks of PEG-IFNα and LAM or ADV combination therapy or monotherapy, were included. Review Manager Software 5.2.0 was used for meta-analysis. Results: No statistical difference was noticed in HBsAg seroclearance (9.9% vs 7.1%, OR = 1.47, 95% CI 0.75, 2.90; p = 0.26) or observed in HBsAg seroconversion (4.2% vs 3.7%, OR = 1.17, 95% CI 0.57, 2.37; p = 0.67) between PEG-IFNα + LAM and PEG-IFNα + placebo for 24-26 weeks follow-up after treatment on hepatitis B e antigen (HBeAg)-positive CHB. Statistical difference was not showed in HBsAg disappearance (10.5% vs 6.4%, OR = 1.68, 95% CI 0.75, 3.76; p = 0.21) but was demonstrated in HBsAg seroconversion (6.3% vs 0%, OR = 7.22, 95% CI 1.23, 42.40; p = 0.03) between PEG-IFNα + ADV and PEG-IFNα for 48-52 weeks treatment on HBeAg-positive CHB By systematical evaluation, there were no differences in HBsAg disappearance and seroconversion between PEG-IFNα + placebo and PEG-IFNα + LAM for 48-52 weeks treatment on HBeAg-positive CHB. There were no differences in HBsAg disappearance and seroconversion between PEG-IFNα + placebo and PEG-IFNα + LAM during 24 weeks to 3 years follow-up after treatment on HBeAg-negative CHB by systematical evaluation. Conclusion: The combination between PEG-IFNα and LAM or ADV was not superior to monotherapy of PEG-IFNα in terms of HBsAg seroclearance or seroconversion
