title: Lipoprotein analyses in varying degrees of glucose tolerance. Comparison between non-insulin-dependent diabetic, impaired glucose tolerant, and control populations.
abstract: Atherosclerosis is the major cause of death in diabetic patients. Lipoproteins and lipids are frequently altered in non-insulin-dependent diabetes. These lipoprotein alterations are of interest because of their possible role in the origin of the accelerated atherosclerosis found in diabetes. Because of the link between lipoproteins and diabetes, serum lipids and lipoproteins were measured in 215 middle-aged patients (107 female, 108 male) with varying degrees of glucose tolerance: control subjects, subjects with impaired glucose tolerance (IGT), and patients with non-insulin-dependent diabetes mellitus (NIDDM). In male subjects, levels of fasting total triglycerides were significantly greater in those with NIDDM compared with control subjects. In female subjects, fasting total cholesterol levels were significantly greater in NIDDM compared with IGT. Both high-density lipoprotein (HDL) cholesterol and HDL2 cholesterol values were significantly lower in both sexes with NIDDM compared with control subjects. Low-density lipoprotein (LDL) cholesterol levels were elevated in the male subjects with IGT. No differences in HDL cholesterol or its subfractions were seen in both sexes with IGT compared with control subjects. Bivariate analyses showed that the reduced HDL cholesterol and HDL subfraction levels were most closely associated with both total triglycerides and weight. This study shows that reduced HDL cholesterol and HDL2 cholesterol levels occur in NIDDM, whereas persons with "impaired glucose tolerance" do not have the dramatic alterations in HDL levels.
