[Antiphospholipid syndrome].

Antibodies against phospholipids in serum, lupus anticoagulant and anticardiolipin antibodies, are strongly associated with venous and arterial thrombosis. A syndrome characterized by these symptoms and the autoantibodies, the antiphospholipid syndrome, is found mostly in patients with systemic lupus erythematosus or related autoimmune disease, but is also found primary without a systemic disease.
