The mechanism underlying the prolonged activated partial thromboplastin time (APTT) seen in some pediatric patients with acquired immunodeficiency syndrome (AIDS) and opportunistic infections was studied. A circulating inhibitor of coagulation was demonstrated in three patients. The inhibitor appears to be an immunoglobulin that interferes with some of the phospolipid-dependent coagulation reactions of the intrinsic pathway. This "AIDS anticoagulant" does not predispose the patient to clinical bleeding despite its ability to cause a marked prolongation of the APTT. As such, careful laboratory diagnosis of the cause of abnormal coagulation test results is necessary for children with AIDS.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
