Abstract:
Objective To investigate the correlation factors associated with therapeutic failure in chronic hepatitis B (CHB) patients who were treated with lamivudine.Methods Clinical data of 224 CHB patients treated with lamivudine were analyzed retrospectively, cases were divided into failure group and success group according to their therapeutic efficacy, the age, sex, pre-treatment levels of ALT and HBV DNA, HBV DNA negative after 24 weeks treatment, Rule medication, HBeAg and HBV YMDD variations of the two groups were compared.Results There were 96 failure cases and 128 success cases who were treated with lamivudine.Compared with success group, pre-treatment levels of ALT, HBV DNA negative rate after 24 weeks treatment, negative rate and Serological conversion rate of HBeAg-positive patients in treatment were lower (P<0.01) , pre-treatment levels of HBV DNA, HBV YMDD mutation rate and irregulardrug use were higher in failure group (P<0.01) .There were no different in age and sex between the two groups (P﹥0.05) .Conclusion Baseline level of ALT and HBV DNA, HBV DNA negative after 24 weeks treatment, Rule medication, HBV YMDD variations and HBeAg change after the treatment can influence the therapeutic efficacy of lamivudine for patients with CHB.
