title: Lipoprotein abnormalities in insulin-dependent diabetes mellitus.
abstract: Despite the increased risk of atherosclerosis in diabetes mellitus, levels of serum cholesterol, triglycerides, low-density-lipoprotein (LDL) cholesterol, and high-density-lipoprotein (HDL) cholesterol were similar in 57 men with insulin-dependent diabetes mellitus (IDDM) and 81 non-diabetic controls. However, substantially lower serum levels of apolipoprotein B, the principal apolipoprotein of LDL, and a concomitant increase in the cholesterol-loading of apolipoprotein B were found in IDDM. The likely changes in LDL density and particle size resulting from this compositional abnormality might lead to accelerated atherogenesis analogous to that seen in type III hyperlipoproteinaemia. In addition, there was an increase in the concentration of cholesterol in the smaller, denser, HDL3 subfraction of serum HDL in IDDM.
