BACKGROUND: The antiviral effect of HBV in different nucleos (t) ide analogues is still not well known. This study was conducted to compare the effectiveness of lamivudine (LMV), adefovir dipivoxil (ADV), telbivudine (LdT), and entecavir (ETV) monotherapy in chronic HBeAg-negative hepatitis B patients with medium load of HBV DNA.
MATERIAL AND METHODS: The effective data of 207 patients treated by LMV (n=43), ADV (n=57), LdT (n=54) or ETV (n=53) were collected and analyzed during 144-week follow-up by retrospective analysis.
RESULTS: Serum HBV DNA levels were significantly lower in the ETV group 1.91±0.45 log10 IU/ml) than in the LdT group (2.09±0.62 log10 IU/ml), ADV group (2.26±0.73 log10 IU/ml), and LMV group (2.08±0.75 log10 IU/ml) at 12 weeks (P=0.0464). HBV DNA levels were maintained at lower levels in the ETV group compared to other 3 groups during follow-up (48 weeks, P<0.001; 96 weeks, P<0.001). Multivariate Cox regression analysis showed that LMV (P=0.001), ADV, (P<0.001), and LdT (P<0.001) were all negative predictors of HBV DNA-negative time, but ETV was not. Viral breakthrough occurred in 34.8% (15/43) of patients in the LMV group; 5.26% (3/57) in the ADV group, 7.4.0% (4/54) in the LdT group, and 0% (0/53) in the ETV group at the end of follow-up. No significant differences were found in mean ALT levels (all P>0.05) or in cumulative normalization rates (P=0.473).
CONCLUSIONS: ETV was more potent and faster for viral response and lower viral breakthrough in medium load of HBV DNA when compared to LMV, ADV, or LdT monotherapy in HBeAg-negative CHB.
