Summary
Haemostatic parameters were assessed before insulin induced hypoglycaemia and 0, 1 and 2 fu after discontinuation of insulin infusion in 7 non-diabetics, aged 28 (22-31) years (mean and range), and 8 juvenile diabetics, aged 3L (27-35) years, with a mean duration of diabetes of 4 years. The patients were normoglycaemic for at least L0 hr before the study.
Platelet aggregation in vitro was induced by lower adenosine diphosphate (ADP) concentrations in the diabetics than in the controls before hypoglycaemia and 0 and 60 min after insulin infusion. Platelet counts decreased significantly in the diabetics after hypoglycaemia, whereas no changes were seen in the control group. The activated partial thromboplastin time (APTT) was reduced in both groups and significantly lower in the diabetics than in the controls 120 min after insulin infusion.
Fibrinogen and factor VIII R: Ag increased after insulin infusion; highest values were seen in the diabetics. The euglobulin clot lysis time (ELT) was reduced in both groups during insulin infusion; L20 min after end of insulin infusion ELT was significantly longer in the diabetics than in the control group.
