title: Diagnosis and management of patients with the antiphospholipid syndrome.
abstract: The antiphospholipid syndrome is an autoimmune disorder characterized by venous or arterial thrombosis, recurrent pregnancy loss, and thrombocytopenia combined with laboratory tests that indicate the presence of antibodies against phospholipid-binding proteins. The antibodies are directed against a complex of phospholipid with a protein such as beta 2-glycoprotein I (beta 2-GPI) or prothrombin and are detected by means of phospholipid-dependent coagulation assays (known as assays for lupus anticoagulants) and by ELISAs that contain beta 2-GPI and a phospholipid (e.g., cardiolipin). The antiphospholipid syndrome can be associated with other connective tissue disorders such as systemic lupus erythematosus or may be the only manifestation of an autoimmune disorder. Management of patients with this disorder usually includes anticoagulation, which has been found to reduce the rate of recurrence of venous and arterial thrombosis as well as the rate of fetal loss.
