Abstract:
OBJECTIVETo investigate the levels of HBsAg in predicting the efficacy of peglated interferon-alpha 2a combined with adefovir dipivoxil (ADV), in HBeAg-positive chronic hepatitis B patients.
METHODSThis trial enrolled 62 HBeAg-positive chronic hepatitis B patients with detectable HBsAg for at least 6 months prior to screening, serum HBV DNA levels of at least 100 000 IU/ml. The efficacy assessment: viral suppression below 100 IU/ml. The patients with HBV DNA < or = 100 IU/ml after 24 weeks therapy were divided into group A, in which monotherapy continued; While the rest were divided into group B, in which ADV was combined until week 48. In group B, at the end-of-treatment, the patients with HBV DNA < or = 100 IU/ml were divided into group B1, the rest were divided into group B2.
RESULTSThere was no significant difference on the baseline characteristics of patients between B1 and B2. There was significant difference on the levels of HBsAg at 12-week and 24-week between B1 and B2; while there was no significant difference on the levels of HBeAg.
CONCLUSIONSThe levels of HBsAg at 12-week and 24-week would be predictors to evaluate the efficacy of combined therapy in HBeAg-positive chronic hepatitis B patients.
