title: Apolipoprotein-E2 and hyperlipoproteinemia in noninsulin-dependent diabetes mellitus.
abstract: The association of apolipoprotein-E2 (apoE2) with hyperlipoproteinemia (HLP) was investigated in 23 noninsulin-dependent diabetes mellitus patients with apoE2 and 24 nondiabetic controls with apoE2. The frequency of HLP was significantly higher in diabetic subjects with apoE2 (73.9%) than in nondiabetic controls (37.5%). HLP in nondiabetic subjects with apoE2 included only type IV (n = 9), whereas HLP in diabetic subjects with apoE2 included type IIb (n = 1), type III (n = 7), and type IV (n = 9). Diabetic patients with apoE2 were characterized by increased levels of plasma triglyceride, total cholesterol (chol), very low density lipoprotein (VLDL)-chol, and apoE and an increased VLDL-chol/VLDL-triglyceride ratio, i.e. the accumulation of remnants. In addition, fasting plasma glucose and hemoglobin-A1 levels were significantly higher in hyperlipoproteinemic diabetic patients with apoE2 than in normolipidemic diabetic patients with apoE2. It is concluded that diabetes (poor metabolic control) predisposes apoE2 (epsilon 2)-carrying subjects to HLP (particularly type III) and that apoE2 may be one factor linking diabetes with HLP and cardiovascular disease.
