Streptokinase-induced platelet aggregation. Prevalence and mechanism.

Abstract

These data demonstrate that SK-induced platelet aggregation is initiated by the binding of anti-SK antibodies to the SK-plasminogen complex located on the platelet surface. SK-induced platelet activation may limit the therapeutic effectiveness of the drug, and in view of the high prevalence of aggregation in a normal population, prospective evaluation of the effects of platelet aggregation during treatment with SK is warranted.
