Fibrinolytic Activity, Autonomic Neuropathy, and Circulation in Diabetes Mellitus

Abstract

In diabetes mellitus the vascular endothelium often produces and releases abnormally low amounts of plasminogen activator, leading to an impaired fibrinolytic system, which might be of importance for the development of angiopathy. In this study tests of autonomic neuropathy (AN) were performed on diabetics without autonomic symptoms. It was discovered that diabetics without AN had a significantly lower mean fibrinolytic response to stimulation than nondiabetic controls, whereas this reduction was not found in those with AN. The suggestion that asymptomatic AN might induce a normalization of the impaired fibrinolytic system in diabetes, and thus have a modifying effect on the rate of development of angiopathy, requires further study to be properly evaluated.
