title: Plasma beta-thromboglobulin concentration at rest and after physical exercise in complicated and uncomplicated diabetes mellitus.
abstract: Plasma beta-thromboglobulin concentration was measured in ten uncomplicated insulin-dependent diabetic subjects, in ten insulin-dependent patients with retinopathy and in ten age- and sex-matched healthy controls, both at rest and after cycloergometric exercise to exhaustion. Resting plasma beta-thromboglobulin was similar in the two patient groups and significantly higher than the control group. After exercising, plasma beta-thromboglobulin rose significantly only in the control group. Platelet hyperactivity is therefore present even in uncomplicated diabetes mellitus and is not influenced by the presence of complications. A chronic overstimulation of platelets could be responsible for the high basal plasma beta-thromboglobulin concentration in diabetes mellitus and for its abnormal behaviour after physical exercise.
