Clinical Significance
The anti-phospholipid syndrome (APS) is a disorder of recurrent vascular thrombosis associated with persistently positive anticardiolipin (aCL) or lupus anticoagulant tests. In patients with APS, anticardiolipin antibodies bind a variety of charged phospholipids, including phosphatidylethanolimine, as well as they do cardiolipin. Lupus patients also have high titers of autoantibodies to various phospholipids, including phosphatidylethanolimine.

Presentations of the syndrome include thrombosis of deep veins of the legs, as well as renal, hepatic, inferior vena cava or sagittal veins. Occlusion of the arterial circulation may be manifested as stroke, ischemic retinopathy, myocardial or bowel infarction, or peripheral gangrene. Thrombosis can occur in veins or arteries of any size. Recurrent pregnancy loss also appears to be the result of thrombosis within the placental vasculature.

Anti-phospholipid antibody tests are supplemental tests and should not be used alone for diagnostic purposes. Diagnosis of anti-phospholipid syndrome must be made in conjunction with other clinical indications.
