Clinical Significance
Cardiolipin antibodies (CA) are seen in a subgroup of patients with autoimmune disorders, particularly Systemic Lupus Erythematosus (SLE), who are at risk for vascular thrombosis, thrombocytopenia, cerebral infarct and/or recurrent spontaneous abortion. Elevations of CA associated with increased risk have also been seen in idiopathic thrombocytopenic purpura, rheumatoid and psoriatic arthritis, and primary Sjögren's syndrome.
