[Changes in the levels of soluble HLA antigens and their light chains (beta 2 microglobulin) in rheumatoid arthritis and systemic lupus erythematosus].
An increase in the level of soluble HLA-A and B antigens in the blood serum of patients with rheumatoid arthritis and systemic lupus erythematosus was observed using IKO-1 monoclonal antibodies and polyspecific alloantisera. This increase was accompanied by the elevation of the concentration of beta 2-microglobulin (the light chain of the molecules of HLA-antigens of the 1st class). A degree of the concentration of soluble HLA-antigens and beta 2-microglobulin depended on a degree of disease activity, a variant of a clinical course and the presence of visceral involvement.
