We studied the subclasses of plasma lipoproteins in normolipidemic, glucose-tolerant male relatives of noninsulin dependent diabetic patients (NIDDM), who represented either the lowest (n = 14) or the highest (n = 18) quintiles of fasting plasma insulin. The higher plasma triglyceride level in the high insulin group (1.61 mmol/l vs. 0.87 mmol/l, P < 0.001) was due to multiple differences in triglyceride-rich lipoproteins. The concentrations of larger VLDL1, smaller VLDL2 particles, and IDL particles were 3.8-fold, 2.5-fold, and 1.5-fold higher, respectively, in the high insulin group than in the low insulin group (P < 0.01 or less). In addition, hyperinsulinemic subjects had VLDL1, VLDL2, and IDL particles enriched in lipids and poor in protein. The lower plasma HDL cholesterol level in the high insulin group (1.20 mmol/l vs. 1.44 mmol/l, P < 0.01) compared to the low insulin group was a consequence of a 27% reduction of HDL2a concentration (P < 0.05) and a significantly reduced percentage of cholesterol in HDL3a, HDL3b, and HDL3c subclasses. On the other hand, the percentages of triglycerides in HDL2b, HDL2a, HDL3a, and HDL3b subclasses were 76%, 79%, 61%, and 50% higher, respectively, in the high insulin group than in the low insulin group (P < 0.01 or less). In the combined group, the concentration of VLDL1 and VLDL2 correlated positively with the concentrations of LDL2 and LDL3 and negatively with HDL2b and HDL2a subclasses (P < 0.05 or less). In conclusion, normolipidemic, glucose-tolerant but hyperinsulinemic relatives of NIDDM patients have qualitatively similar lipoprotein abnormalities as NIDDM patients. These abnormalities are not observed in insulin-sensitive relatives, suggesting that they develop in concert with insulin resistance.
