Abstract: Objective To investigate the clinical efficacy of pegylated interferon α-2a(Peg-IFNα-2a) combined with adefovir (ADV) in treatment of patients with HBeAg-positive chronic hepatitis B(CHB). Methods Randomized controlled trials (RCT) involving peg-IFNα-2a combined with adefovir in treatment of patients with HBeAg-positive CHB,were searched from Pubmed,Wanfang Database,Chongqing VIP database,CNKI database,etc,from January,2004 to January,2014,of which the quality were underwent rigorous assessment and data were analyzed by Stata/SE software(version 12). Results 7 allegeable RCT (a total of 529 cases) were included. There were 261 patients receiving peg-IFNα-2a combined with ADV and 268 receiving peg-IFNα-2a alone. Systematic evaluation showed that HBV DNA negative rate in combinational therapy-treated patients with CHB at the end of week 48 was significantly higher as compared to patients receiving interferon alone[OR=1.20,95% CI=(1.01,1.43)];the HBeAg seroconversion rate at 48 w in patients receiving combinational therapy was also significantly higher than that in the controls[OR=1.24,95% CI=(1.02,1.52)];a significant bias of results was found for serum ALT normalization rate [bias_p=0.012,bias_95 CI=(1.442998,6.467852)]. Conclusions Peg-IFNα-2a combined with ADV significantly improves HBV DNA negative and HBeAg seroconversion rate in patients with HBeAg-positive CHB.
