[Complement level in serum from patients with chronic hepatitis].

Abstract

In persons with chronic active hepatitis (35) and chronic persistent hepatitis (23) the CH 50 values, Clq, Cls, C4, C3, C5, and C9 as well as Cl Inh and C3A levels have been determined. The concentration changes of complement (C) were not conditioned by the existence in serum HBs. The degree of changes in values of C in all patients is in determinate relation with the levels of bilirubin, transaminases and immunoglobulins (G, M, A). The degree of determinate changes of C depends on the severity of clinical picture. The degree of Cl Inh elevation is in correlation with intensity of complement activation. The noticed dissociated values of subcomplements Clq and Cls suggest the presence of immune complexes which could influence the HBsAg detection.
