[The immunological diagnosis of chronic viral hepatitis].
Chronic viral diseases of the liver are associated with changes in immune reactions mediated by T and B lymphocytes and dependent in severity on etiological factor (virus of hepatitis B, delta, C, their combination), the disease stage (hepatitis, cirrhosis), the process activity, kind of immune correction. HBsAg, viral hepatitis B marker, was detected in 21.2% of 1400 cases with chronic active hepatitis and liver cirrhosis. 32% of HbsAg-seropositive patients had antibodies to delta-antigen. Antibodies to HBsAg, HCV were found in 27.7 and 14.9% of the above patients. Chronic viral diseases of the liver with persistence of HBV, HDV and HCV markers are characterized by a complex of immune disorders, including a moderate rise in peripheral blood of IgM, IgG, IgA, IgE, Ig kappa, lambda, immune complexes, cryoglobulins, autoantibodies to subcellular structures as well as changes in regulatory (suppressor, helper) and effector (lymphokine-producing) functions of T lymphocytes, inhibition of phagocytosing capacity. The above shifts in immune status, clinical and biochemical activity of the disease are more pronounced in chronic active hepatitis with HCV markers compared to BHV. Of maximal intensity they were in combined viral infection HBV+HDV or HBV+HCV.
