[Secondary immunopathology in patients with an acute streptococcal infection].

The authors studied the activity of complement, nonspecific adaptive reactions of the body, the presence of antibodies to cross-reacting antigens of Streptococcus, the concentration of circulating immune complexes, some cellular characteristics of the immunogram in patients with different forms of streptococcal infection. The changes revealed allow a conclusion about the presence of autoimmune processes, most pronounced in chronic and recurrent forms of diseases. In the formation of streptococcal infection relapses, of the role is pathology of the complement system in combination with disorders in other components of nonspecific anti-infection resistance.
