Abstract
Abstract
Seventeen patients with idiopathic autoimmune thrombocytopenic purpura were studied in order to establish whether the amount of platelet-bound antibody influenced the rate and site at which these platelets were destroyed. Platelet-bound antibody was measured by a quantitative antiglobulin consumption technique, and platelet survival and sites of sequestration were determined by the use of 51Cr-labeled platelets and surface radioactivity measurements. A correlation significant at the 5% level was observed between the amount of platelet-bound antibody and the rate of platelet destruction. A highly significant correlation (p less than 0.001) existed between antiplatelet antibody and spleen: liver surface radioactivity ratios, demonstrating that greater amounts of antibody bound to platelets result increasingly in their destruction within the liver.
