Association of serum lipids and lipoproteins with plasma C-peptide concentration in non-insulin-dependent diabetic and non-diabetic subjects.
Serum lipids and lipoproteins were studied in 149 non-insulin-dependent diabetic subjects treated with diet or oral drugs (75 men, 74 women) and in 101 nondiabetic control subjects (49 men, 52 women) in relation to endogenous insulin secretion capacity measured by plasma C-peptide response to intravenous glucagon. Serum HDL- and HDL2-cholesterol concentrations were lower and VLDL-cholesterol and total and VLDL-triglyceride concentrations higher in subjects with high C-peptide response (above the median) than in subjects with low C-peptide response (lower or equal to median) both in diabetic and control subjects of both sexes. Adjustment for the effect of obesity abolished these differences in serum lipids and lipoproteins in diabetic subjects but not in control subjects. This may indicate that obesity has stronger influence on serum lipids in diabetic subjects than in nondiabetic subjects.
