[Systemic lupus erythematosus].

Systemic lupus erythematosus (SLE) is a multisystemic inflammatory rheumatic disease of unknown etiology. It is understood that immune complexes have dominant role in the pathogenesis of the disease with vasculitis being the basis of many clinical manifestations. SLE is considered to be the autoimmune disease because of many autoantibodies, some of them with the known pathogenetic role. Characteristic features of the disease are skin manifestations, arthritis, serositis as well as various tissue and organ lesions, particularly that of the kidney and nervous system. On the basis of disease activity and organ involvement the decision on the institution of immunosuppressive therapy is made.
