Abstract

Plasma lipoprotein concentration, composition, and size were evaluated in two common familial forms of hypertriglyceridemia and compared with those in normal subjects. The very low density lipoproteins (VLDL) were triglyceride-enriched in familial hypertriglyceridemia (triglyceride/apoprotein B ratio: 25.7 +/- 8.9) as compared to normal (9.6 +/- 12.2, P < 0.001) or familial combined hyperlipidemia (9.7 +/- 3.3, P < 0.001). The diameter of VLDL was larger in familial hypertriglyceridemia (3.27 +/- 0.28 pm) than in familial combined hyperlipidemia (2.87 +/- 0.16 pm, P < 0.02). Although in familial hypertriglyceridemia VLDL tended to be larger, and in familial combined hyperlipidemia VLDL tended to be smaller than normal (3.08 +/- 0.48 pm), neither of these differences were significant. While VLDL was normally distributed in the control population, the size was skewed to larger particles in familial hypertriglyceridemia with fewer small particles (P < 0.05) and skewed to smaller particles in familial combined hyperlipidemia with fewer large particles (P < 0.05). VLDL was reciprocally related to low density lipoproteins (LDL) in familial combined hyperlipidemia (r = -0.80 to -0.87) suggesting that the concentrations of these indivi...Continue Reading

ApoE, Lipids & Cholesterol

Serum cholesterol, triglycerides, apolipoprotein B (APOB)-containing lipoproteins (very low-density lipoprotein (VLDL), immediate-density lipoprotein (IDL), and low-density lipoprotein (LDL), lipoprotein A (LPA)) and the total cholesterol/high-density lipoprotein (HDL) cholesterol ratio are all connected in diseases.
