Abnormal coagulation profiles were identified in ten patients with the acquired immunodeficiency syndrome (AIDS) associated with opportunistic infections and malignancies. Activated partial thromboplastin times were elevated in all patients; three of seven had elevated prothrombin times. All patients had lupus-type anticoagulants characterized by rapid prolongations of the partial thromboplastin time in mixing studies, prolonged dilute thromboplastin inhibition assays, and increased Russell viper venom clotting times. Ivy bleeding times were prolonged in three patients with defective platelet aggregation. The lupus anticoagulant was isolated from the sera of healthy heterosexual men and from patients with AIDS with and without the lupus anticoagulant, and in the presence and absence of opportunistic infections. Both polyclonal IgM and IgGλ from plasma with lupus anticoagulant interfered with clotting studies and platelet aggregation. The inhibitors usually accompanied active opportunistic infections and tended to disappear with successful resolution of infection.
