    Notes: Abstract A 48-year-old male patient was admitted with acquired immunodeficiency syndrome (stage III, Centers for Disease Control 1993) and viremic hepatitis B. Blood CD4 count was 15/μl. Discontinuation of prednisolone, previously prescribed by the patient's family practitioner because of elevated liver enzymes, resulted in severe hepatitis (alanine aminotransferase 〉 300U/1). Administration of interferon-α, (9 × 106U s.c. 3 × weekly) was initiated. Serum markers of viral replication disappeared, and aminotransferase levels returned to normal within a few weeks. The patient's serum was found negative for HBsAg after 3 months. Immunohistochemical analysis of liver biopsies before and during interferon therapy showed disappearance of all hepatitis B virus antigens and a marked reduction in inflammatory activity. Hepatitis B virus seroconversion remained stable until the patient died from the syndrome 2 years later. This case shows that in spite of severe HIV-associated immune deficiency with CD4 counts constantly below 100/μl, interferon-α can lead to sustained serological and histological improvement of viremic hepatitis B. Previous administration and discontinuation of cortisone may have helped to reach this effect.

    Notes: Summary Hepatitis B virus and the human immunodeficiency virus are similarly transmitted. Individuals with preexisting HIV infection have a higher chance to become HBsAg carriers than do anti-HIV negative persons. Cytotoxic T cells with specificity for HBcAg, that are under the control of HBcAg-specific helper T cells, are responsible for liver injury. There is good evidence that HIV infection lowers inflammatory activity, is associated with milder liver histology, high levels of viral replication and low seroconversion rates. In addition interferon alpha therapy is less effective in anti-HIV positive subjects. The immune response against HBsAg is helper T-cell dependent and vaccination against hepatitis B is of low effectiveness. In addition, vaccination against hepatitis B may activate the HIV disease and is, therefore, presently not to be recommended.
