title: Anticardiolipin antibodies: their presence as a marker for lupus anticoagulant in pregnancy.
abstract: A solid phase ELISA was developed to investigate the association between anticardiolipin antibodies and lupus anticoagulant in pregnancy. Twenty-seven pregnant women with a history of recurrent fetal losses or systemic lupus erythematosus (SLE) were tested for the presence of lupus anticoagulant, anticardiolipin antibodies, antinuclear antibodies (ANA) and anti-single-stranded DNA antibodies. Nineteen women with a total of 49 previous unsuccessful pregnancies were found to have lupus anticoagulant and anticardiolipin antibodies. Three women who had suffered four fetal deaths from six pregnancies had anticardiolipin antibodies without lupus anticoagulant. Cardiolipin antibodies were not detected in the remaining five patients. This assay for measuring anticardiolipin antibodies appears to provide a simple and inexpensive method of identifying women at risk of fetal death from the adverse effects of lupus anticoagulant.
