Abstract
The high incidence of cardiovascular morbidity and mortality in non-insulin-dependent diabetes mellitus with albuminuria cannot be fully explained by the presence of standard cardiovascular risk factors. We assessed some pathogenic factors of diabetic vascular atherosclerotic damage in 72 non-insulin-dependent diabetes mellitus patients controlled by diet alone and 60 healthy controls. Our study aim was to assess the early onset of these alterations and to correlate them with the presence of microalbuminuria. We determined their incidence in two carefully selected groups of diabetic patients without clinical signs of cardiovascular risk and complications, where diet alone achieved glycometabolic balance. Microalbuminuric patients had an alterated oxide-reductive balance and elevated values of plasminogen activator inhibitor, tissue plasminogen activator, von Willebrand factor, endothelin-1 and betathromboglobulin compared with the normoalbuminuric diabetics and controls. Our findings support the hypothesis that a state of endothelial dysfunction characterized by altered oxide-reductive balance, modified hemostasis and changes in the endothelial barrier properties occurs much earlier in non-insulin-dependent diabetic patient especially in diabetics with microalbuminuria. In addition, alterations in the oxide-reductive balance, and hemostasis occur early and may be an underlying cause of microangiopathic complications in microalbuminuric diabetics.
