[Antibodies to anticoagulants in rheumatic autoimmune diseases]

The systemic lupus erythematosus (SLE) and the rheumatoid arthritis (RA) as the classic autoimmune diseases exhibit a great number of autoantibodies. Some of them are anticoagulants. Besides inactivating inhibitors against single coagulation factors interfering anticoagulants are known, belonging to the group of anti-phospholipid antibodies and detected as the lupus anticoagulants or anticardiolipin antibodies. Anti-phospholipid antibodies 184 patients with SLE or RA had been checked for. An enzyme immuno assay was used for detection of the anti-cardiolipin antibodies. The relations between occurrence of the anti-cardiolipin antibodies and vascular processes as well as other immunologic parameters had been tested for clinical relevancy.
