title: HBsAg positive secondary autoimmune active chronic hepatitis. Immunogenetic aspects.
abstract: Observations were made in a group of 120 patients with active chronic hepatitis (ACH), using demonstration of HBsAg presence, structural study of the peripheral blood mononuclear cell population by means of scanning electron microscopy (SEM) and typing of HLA-A, B and C antigens. From the whole group 22 patients were proved to have an autoimmune form of ACH secondary to infection with hepatitis B virus (HBV). The authors consider that the diagnostic value of the ratio between B and T lymphocytes (studied by SEM) is relative but the demonstration of an increased percentage of monocytomacrophage cells and the presence of "killing phenomenon" clearly reflect a more severe hepatic inflammation. A higher incidence of the HLA-Bw35-Cw4 was observed particularly in the HBsAg positive forms of ACH and in the HBsAg positive secondary autoimmune forms. The authors discuss the utility of these observations when the opportunity of corticotherapy has to be established.
