    Abstract:
    OBJECTIVES: To investigate the efficacy of by combining a 12-week course of lamivudine in those HBeAg-positive hepatitis B patients receiving peginterferon alfa-2a (peg-IFN alpha-2a) therapy. METHODS: A total of 58 patients initiated a 52-week course of peginterferon alfa-2a were enrolled and divided into 3 groups. The patients with HBV DNA undetectable or HBeAg negative at week 12 were divided into group A, in this group treatment continued to week 52 with peg-IFN alpha-2a alone; The rest patients were divided into group B1 and B2, in group B1, lamivudine was combined at a course of 12 weeks, while in group B2 treatment continued to week 52 with peg-IFN alpha-2a alone. Clinical responses were assessed at week 52. RESULTS: 8 out of 58 patients achieved undetectable HBV DNA or HBeAg loss at week 12 and divide into group A. In this group the HBV DNA loss rate, HBeAg seroconversion rate, HBsAg loss rate and ALT normalization rate were 100% (8/8), 75% (6/8), 0% (0/8) and 100% (8/8) respectively at the end of treatment. In this group the HBV DNA loss rate, HBeAg seroconversion rate, HBsAg loss rate and ALT normalization rate were 100% (8/8), 75% (6/8), 0% (0/8) and 100%(8/8) respectively at the end of treatment. The rest 50 patients without early response to peg-IFN alpha-2a at week 12 were divided into group B1 (24 patients enrolled) and B2 (26 patients). At the end of treatment, the HBV DNA loss rate, HBeAg seroconversion rate, HBsAg loss rate and ALT normalization rate in Group B1 were 50% (12/24), 38% (9/24), 4% (1/24) and 63% (15/24) respectively, and 31% (8/26), 27% (7/26), 0% (0/26) and 35% (9/26) respectively in group B2. CONCLUSION: Those patients with early responses to peg-IFN alpha-2a therapy can achieve high clinical responses at the end of 52-week treatment. The combining therapy of lamivudine for a course of 12-weeks can improve the clinical responses for the patients without early responses to peg-IFN alpha-2a.
