Anticardiolipin antibodies (aCL) are associated with thrombotic phenomena including cerebral ischemia in young adults. Although aCL are directed to a neoepitope formed by phospholipid and beta2-glycoprotein I (beta2-GPI), immunoassays based on cardiolipin as target antigen are widely used. We previously demonstrated that 47% of aCL-negative systemic lupus erythematosus (SLE) patients had antiphospholipid antibodies (aPL) to epitopes other than cardiolipin, and we found an association between aPL to noncardiolipin antigens and thrombosis. We now assess the prevalence and clinical significance of noncardiolipin aPL in young adults with cerebrovascular disease of undetermined etiology.
