[Lupus and thrombophilia : Antiphospholipid syndrome].

Even early on thromboembolic events were observed in patients with systemic lupus erythematosus (SLE) until the antiphospholipid syndrome (APS) was described in the 1980s as an independent disorder. The APS is a systemic autoimmune disease often overlapping with SLE in which antiphospholipid autoantibodies, including lupus anticoagulant, can cause a hypercoagulation state, which clinically by definition is manifested as arterial and venous occlusions or pregnancy complications. The pathophysiology has not yet been entirely delineated and the clinical spectrum of associated concomitant manifestations is large. As the mortality is increased with SLE and simultaneous APS, focused diagnostics and risk assessment are indispensable. According to the recently published recommendations of the European League Against Rheumatism the therapeutic strategy comprises individualized secondary prevention of thromboembolic complications by means of anticoagulation (with unaltered importance of vitamin K antagonists) and thrombocyte aggregation inhibition, usually lifelong. Statins and antimalarial drugs are recommended for vascular protection while immunosuppressive treatment has not so far been sufficiently proven for APS but remains the subject of current research.
