Certain strains of Escherichia coli producing verotoxin have been isolated in the stools of patients with the haemolytic uraemic syndrome. A platelet aggregating activity has been found in normal plasma after incubation with verotoxin at 37 degrees C for 24 h. This activity, unlike neuraminidase, has an effect that is independent of changing factor VIII related antigen, but requires the IIA and...

Patients affected by Glanzmann's thrombasthenia often require blood and platelet transfusions due to bleeding. They may develop antibodies against platelet antigens and become refractory to platelet transfusions. In this study we present our approach to platelet transfusion in a thrombasthenic patient with platelet antibodies directed against gpIIb/IIIa. We found that platelets from two HPA1b/b...
