Abstract:
Objective To investigate the efficacy of Telbivudine as sequential therapy for HBeAg positive CHB patients with pegylated IFNα-2a (PEG-IFNα-2a)treatment failure.Methods After a 48-week pegylated IFNα-2a therapy,102 HBeAg positive CHB patients,whose HBeAg expression was positive and HBV DNA load was Detectable,were enrolled.These patients were randomly divided into two groups.Group A,included 52 patients,were treated with Telbivudine as a sequential therapy after a 3 months or longer wash-out period.Group B,included 49 patients,were treated with Telbivudine as a sequential therapy without wash-out period.The rate of ALT normalization,HBeAg seroconversion,the negative rate of HBV DNA and the level of creatine kinase in the two groups were observed and compared,respectively.Results HBeAg seroconversion of Group A at 3,6,12 months was 7.69％,15.3％,21.1％,respectively.HBeAg seroconversion undetectable of Group B at 3,6,12 months was 22.4％,32.6％,38.8％,respectively.Furthermore,there was statistically significant difference in HBeAg seroconversion between the two groups (P ＜ 0.05).However,there were not statistical difference in the rate of ALT normalization,the negative rate of HBV DNA and the level of creatine kinase between the two groups at 3,6,12 months.Conclusion Telbivudine,which was used as a sequential therapy without wash-out period for HBeAg positive CHB patients after PEG-IFNα-2a treatment failure,was secure.Moreover,HBeAg seroconversion of patients treated with Telbivudine as a sequential therapy without wash-out period was higher than those with wash-out period.
