[Serological markers of viral infections and various indicators of immunity in patients with hemophilia].

The authors have studied the incidence rate for markers of viruses of AIDS (HIV), hepatitis B (HBV) and cytomegalia (CMV), as well as certain parameters of antiinfectious defense in hemophilia patients. A high incidence rate of HBV and CMV markers was established in the investigated patients, and among them no seropositive subjects, by antibodies to HIV, were detected. In the presence of a low incidence rate of chronic HBsAg-carriership in this category of patients, a significant number of immune subjects was observed, that correlated with a relative stability of such immunity parameters as concentration of serum immunoglobulin G and the level of circulating immune complexes.
