HAEMOSTASEOLOGICAL CHANGES IN DIABETIC CHILDREN (HUMAN INSULIN VERSUS PORCINE INSULIN
Changes of haemostaseological parameters are involved in pathogenesis of diabetic angiopathy. However it is not yet clear whether they are cause or consequence of the endothelial damage. We investigated coagulation parameters in 84 children with type I diabetes mellitus without clinical signs of vascular disease.Compared to the control group no significant changes could be seen in fibrinogen, plasminogen, protein C, α 1 antichymotrypsin, β-thrombo-globulin and ristocetin - induced aggregation.Additionally we could observe significant differences in patients treated with human insulin to those treated with porcine insulin. Spontaneous platelet aggregation (PAT III) and factor VIII C correlated to the duration of diabetes. Also to the mean metabolic equilibrium (HBA1) correlations could be found. Spontaneous platelet aggregation seems to be a useful parameter to assess the onset of atherosclerotic diseases in diabetic children. High values of von Willebrand factor may indicate reversible and/or irreversible damage of vascular endothelium.
