Antiphospholipid antibodies have been associated with a clinical syndrome consisting thrombosis and recurrent, unexplained fetal loss.


The literature pertaining to stroke associated with antiphospholipid antibodies, with emphasis on stroke in young adults, was reviewed.


Antiphospholipid antibodies are an independent risk factor for stroke in young adults in five of six studies. Multiple antiphospholipid specificities or the Lupus Anticoagulant were tested in addition to anticardiolipin antibody in these studies. In the single study that found no increased risk for stroke, only anticardiolipin antibody was tested. Only one of these studies evaluated for risk of recurrent stroke in young adults with antiphospholipid antibodies and found it to be increased. No treatment trials have been conducted in young adults with antiphospholipid antibodies and stroke. In the single treatment trial comparing aspirin and low-INR producing doses of warfarin to prevent recurrent stroke, both were found to be equally effective.


Antiphospholipid antibodies, particularly Lupus Anticoagulant, is an independent risk factor for first and possibly recurrent ischemic stroke in young adults. The best therapeutic strategy for preventing antiphospholipid antibody-associated recurrent stroke is not clear.
