Background and Aims:Monotheray with early generation nucleos(t)ide analogues followed with add-on remedy according to virological response at week 24 or 48 may improve treatment efficacy. This study compared the virological response profiles of patients with chronic hepatitis B (CHB) treated with de-novo combination LAM+ADV or lamivudine or adefovir optimal therapy at week 48.
Methods: Treatment-naïve chronic hepatitis B patients were recruited, then were split into 3 groups: 1) LAM+ADV, treated with LAM plus ADV for 104 weeks; 2) LAM optimal group, treated with LAM for 48 weeks, then ADV was added to those with poor virological response or virus breakthrough for the subsequent 56 weeks. 3) ADV optimal group, treated with ADV for 48 weeks, then LAM was added to those with poor virological response or virus breakthrough for the subsequent 56 weeks. Poor virological response was defined as a decrease in serum HBV DNA of〈2 log10 copies/mL at week 48 when compared with that at baseline. Virological breakthrough was defined as an increase in serum HBV DNA by 〉1 log above nadir. HBV DNA undetected rate defined as the proportion of patients with HBV DNA of <500 copies/ml. HBV virological response, serological response and ALT were monitored at treatment week 12, 24, 48,104.Results: After 104 weeks, 174 cases were analyzed. The rate of undectected HBV-DNA, HBeAg seroconversion and the deline of serum HBeAg leves was obviously increase in LAM+ADV group(P〈0.05). The deline of serum HBeAg of LAM+ADV group was significant higher than LAM and ADV group at week 48(P〈0.05). The LAM+ADV group had no viral breakthrough, but LAM group appeared 12 ,ADV group appeared 1 in total after 104 weeks.
Conclusions: When compared with LAM or ADV optimal therapy at week 48, de-novo LAM plus ADV combination therapy in CHB patients has a more favorable virological response, serological response and a lower viral breakthrough rate at week 104.
