    Abstract:
    A randomized controlled study of one course of vidarabin was carried out in 30 patients with HBs Ag, HBe Ag, DNAp, positive chronic active hepatitis: 15 patients were treated with vidarabin given intravenously (15 mg/kg/day for 7 days then 7.5 mg/kg/day for 14 days); the other 15 patients received a placebo for 21 days. During treatment, DNA polymerase activity fell dramatically in 13 treated patients and in no controls (p less than 0.001). Six months after inclusion, ALT normalization was observed in 40 p. 100 of the treated patients and 6 p. 100 of the controls (p less than 0.05), a decrease in inflammatory activity on liver biopsies was observed in 70 p. 100 of the treated patients and 20 p. 100 of the controls (p less than 0.05), a permanent lost of DNA polymerase and of HBe Ag occurred in 33 p. 100 and 13 p. 100 of the treated patients and 20 p. 100 and 7 p. 100 of the controls, respectively. In addition, a second course of vidarabin was administered to the 12 patients who were still HBe Ag positive 6 months after the first course. During the next 6 months, 8 patients lost DNA polymerase and 4 lost HBe Ag. Altogether, the final score of durable inhibition of HBV replication was 11/15 (73 p. 100) within one year. The above results demonstrate that one course of vidarabin can significantly improve ALT and liver inflammatory activity but the effect upon HBV replication is only transient. A second course does however increase efficacy on HBV replication without additional side effects.
