Objective: To evaluate 1) the hemorrheologic and hemodynamic effects of glyceryl trinitrate in patients with non-insulin-dependent diabetes mellitus and 2) the influence of antioxidants on these effects.
Design: Case-control study.
Setting: University hospital clinic.
In order to evaluate whether the presence of a positive family history of diabetes (PFH) may have a negative impact on both glucose metabolism and cardiovascular risk factors, we studied parameters of carbohydrate metabolism (fasting and 2h-plasma glucose, HbA1c) and beta-cell function (fasting insulin and C-peptide), as well as the levels of some established cardiovascular risk factors (total cholesterol and triglycerides, HDL-cholesterol, blood pressure) in 729 subjects who were seen within the frame of a Regional Health Program in Taranto, South Italy. According to the NDDG criteria, 147 men and 235 women had normal glucose tolerance, 54 men and 66 women non-diagnostic OGTT, 65 men and 79 women impaired glucose tolerance, and 45 men and 58 women newly-diagnosed Type 2 diabetes. There was a continuous increase of PFH across the categories of glucose intolerance (p < 0.

Research Design And Methods: Two groups of 10 insulin-requiring diabetic patients, matched for duration of disease and metabolic control, received daily vitamin E supplementation of 1200 and 600 mg, respectively, for 2 mo. A third group of 10 diabetic patients, matched for duration of disease and metabolic control, served as the control group and received placebo.
