title: The role of antiphospholipid antibodies in stroke.
abstract: Antiphospholipid antibodies may be found in about 10% of all subjects with acute stroke but probably are present in as many as 50% of young persons with stroke and perhaps even in high prevalence in persons who have coexisting rheumatologic diseases such as SLE. In these latter groups, the association may be as high as 50%. Probably the best related syndrome is Sneddon's syndrome, which has a high prediction to dementia. Furthermore, vascular dementia may be a prominent feature of the aPL syndrome in subjects under age 55. The cause and mechanism by which aPL are related to stroke remain unknown. Likewise, there is a dearth of information about prognosis, morbidity, and stroke recurrence in subjects who have these immunoglobulin markers. Thus therapy remains very problematic, but current strategies include the use of antiaggregate therapy, warfarin, and limited implementation with prednisone and plasmaphoresis. Data that demonstrate clear cut benefit of any of these therapies are lacking. Ultimately, unraveling these crucial problems concerning the aPL syndrome may provide great insight into certain stroke mechanisms.
