ABSTRACT
OBJECTIVES:
To evaluate the efficacy and safety of famciclovir on the decreasing levels of serum HBV-DNA and ALT and HBeAg/antiHBe seroconversion in chronic hepatitis B patients irresponsive to 3 months treatment with alpha interferon.METHODS:
Two hundred and nineteen patients with chronic HBV infection, defined as positive HBsAg, HBeAg and HBV DNA, were enrolled and randomly half-and- half put into famciclovir and placebo groups. The two groups received either famciclovir 500 mg tid or a placebo treatment for 24 weeks, and then were followed-up for another 24 weeks with no treatment.RESULTS:
At the end of 24 weeks, the log value of HBV DNA dropped from 6.54+/-1.26 to 5.70+/-2.03 in the famciclovirt group and were elevated from 6.30+/-1.32 to 6.51+/-1.65 in the placebo group (P < 0.01). The rate of cases with persistence HBV DNA dropped 2 log of quantity in the famciclovir group and was 28.28% (28/99); it was 9.47% (9/95) in the placebo group (P < 0.01). Those with persistence negative HBV DNA was 28.28% (28/99) in the flamciclovir treated group and 14.74% (14/95) in the placebo group (P < 0.05). Those persistently being HBeAg negative were 7.69% (7/91) in the famciclovir treated group and 3.33% (3/90) in the placebo group (P > 0.05). The HBeAg/antiHBe seroconversion was 4.40% (4/91) in the famciclovir group and 2.22% (2/90) in the placebo group (P > 0.05). The percentage of cases with normal of ALT level was 15.15% in the famciclovir group and 6.35% in the placebo group (P < 0.05).CONCLUSION:
Famciclovir is effective in inhibiting HBV DNA replication and in decreasing serum ALT levels. The rate of HBeAg/antiHBe seroconversion in the famciclovir treated group was similar to that of the placebo group. Famciclovir was well tolerated without severe adverse effects during our treatment.
