    Abstract:
    The main problem of children with HBeAg positive hepatitis B and associated hepatitis D is progression to liver cirrhosis with decompensation of liver function and need for liver replacement therapy within 15-20 years after infection. To determine whether interferon-alpha (IFN-alpha) therapy has a positive effect on HBV replication and inflammatory activity, we evaluated clinical and serological data of 8 children treated with IFN-alpha and 6 historic control patients without treatment. 4 of the nontreated patients seroconverted from HBeAg to anti-HBe between 7 to 17 years after initial diagnosis and showed decreased inflammatory activity in the liver. In the treatment group, the rate of seroconversion to anti-HBe (3 early, 2 late seroconverters) corresponded well to former trial results obtained in patients exclusively infected by HBV. Serum aminotransferase levels decreased or normalized in seroconverted children. In chronic HBV infection with associated hepatitis D (HDV) infection--compared to the spontaneous course of the disease--IFN-alpha therapy reduced inflammatory activity by earlier seroconversion to anti-HBe in responding patients. Moreover, viral replication and infectivity of hepatitis B was markedly reduced, but no effect on replication of HDV could be documented. Although long-term effects cannot be exactly estimated, at present IFN-alpha remains the only available treatment for HBeAg and anti-HDV positive children and seems to be of benefit for responding patients.
