Metabolic control affects plasma lipid and apolipoprotein levels in women, but not in men, with IDDM.
In order to evaluate if in insulin-dependent diabetes lipid and apolipoprotein levels are differently affected by metabolic control in men and women, we measured the concentrations of fasting plasma glucose, mean plasma glucose, glycosylated hemoglobin, total cholesterol, HDL-cholesterol, LDL-cholesterol, triglycerides, and apolipoproteins A and B in 94 sex matched patients. Diabetic men and women were strictly comparable as far as age, relative body weight and metabolic control were concerned. In women, total and LDL cholesterol, triglycerides and apolipoprotein A correlated positively with HbA1 but not with fasting and mean plasma glucose. In men, no correlation between metabolic control and lipid and apolipoprotein levels was found. We conclude that, in diabetic women, the degree of metabolic control may affect the concentrations of plasma lipids, thus explaining, at least in part, the increased risk for coronary atherosclerosis in these patients.
