Background/Aims: The aim of this study was to compare the serial sequence changes of precore and core promoter regions in hepatitis B e antigen (HBeAg)-positive chronic hepatitis B (CHB) patients with and without HBeAg clearance in lamivudine treatment. Methods: Precore and core promoter genes of the hepatitis B virus (HBV) were sequenced from five serial serum samples of 74 HBeAg-positive CHB patients received lamivudine for 9-12 months (34 complete responders and 40 non-responders). Conclusions: T1762/A1764 mutation (not A1896) played an important role in lamivudine-induced HBeAg clearance. Moreover, T1773, C1802, G1803, T1846, A1850, and C1858 mutations might have significant correlation with HBeAg nonseroconversion. (c) 2005 European Association for the Study of the Liver.
