[Immunological disorders in different clinical variants of rheumatoid arthritis].

The authors present the current data on the disorders of immune functions in patients suffering from rheumatoid arthritis (RA). Provide evidence for the pathogenetic heterogeneity of the known clinical patterns of RA, mainly seronegative and seropositive varieties, with special reference to the differences in the lowering of the activity of nonspecific T suppressors, to the influence of the factor of necrosis of alpha-tumor and alpha- and beta-interferons on B lymphocyte proliferation, and to the effects of synovial exudate from seropositive and seronegative patients. Demonstrate the results of integral estimation of the disorders of several characteristics of the immune system in RA patients with the use of the image recognition program. It is concluded that the clinical polymorphism of RA is specified by the pathogenetic heterogeneity of the disease based on varieties of combined normal and altered functions of different components of the immune system.
