Increased von Willebrand factor in diabetes mellitus.
Abnormal platelet function may play a role in the genesis of vascular complications in diabetes mellitus. We measured plasma levels of ristocetin-Willebrand factor and factor VIII antigen in 75 subjects and also measured aggregation-enhancing factor in subsets. We found increased levels of ristocetin-Willebrand factor in all groups of diabetics studied, even in mild diabetics free of vascular disease. Factor VIII antigen was increased only in diabetics with vascular disease. We could not find an aggregation-enhancing factor in any group.
