Small dense LDL concentration is closely associated with serum apolipoprotein B, comparisons of non-LDL cholesterol or LDL cholesterol

Small dense low-density lipoprotein (sd LDL) is more atherogenic than large buoyant (lb) LDL, which is relatively high in particle number (as estimated by apolipoprotein [apo] B) and poor in cholesterol (C) content. Because recent epidemiological studies have shown that serum apo B is a stronger predictor of the risk of coronary heart disease (CHD) than LDL-C, we assumed that this strong predictive power of apo B for CHD is attributable to a close association with sd LDL concentration. On the other hand, non-HDL-C has been proposed as an integrated CHD risk marker containing all atherogenic apo B-containing lipoproteins. We examined which apo B or non-HDL-C is superior marker in reflecting sd-LDL particles. Eighty-one subjects with dyslipidemia were studied. Sd LDL (density, 1.044 approximately .063g/ml) and large buoyant LDL (density, 1.019 approximately 1.044g/ml) were separated by the ultracentrifugation method and LDL size was measured by gradient gel electrophoresis. LDL-C, non-HDL-C, and apo B were highly associated with each other(r=0.78 approximately 0.87), and all were associated with C, apo B, and TG in sd-LDL. However, multivariate regression analysis revealed that only apo B was constantly and independently associated with sd-LDL concentrations. Mean LDL diameter was negatively associated with apo B but not with non-HDL-C. These results suggest that apo B is superior to non-HDL-C in reflecting a potent atherogenic lipoprotein, sd-LDL, which may explain a potent predictive power of apo B for CHD.

Metabolic syndrome and small dense LDL-cholesterol

Recently, small dense low-density lipoprotein (sd-LDL) has been highlighted as a new risk factor for CHD. Sd-LDL is also closely associated with insulin resistance and hypertriglyceridemia, suggesting a high prevalence of these atherogenic particles in metabolic syndrome. It has been proposed that increased triglyceride (TG) production in the liver due to insulin resistance preferentially produces TG-rich very-low density lipoproteins (VLDL1), which finally generate sd-LDL particles. Sd-LDL is usually measured by electrophoresis or ultracentrifugation, but these methods are too laborious for general clinical use. Recently, we established a simple method for the quantification of sd-LDL-cholesterol (C) using heparin-magnesium precipitation with a filter, which selectively detects cholesterol in the denser LDL fraction with a density(d) =1.044-1.063g/ml. Patients with coronary heart disease (CHD) had substantially increased sd LDL-C levels, while their LDL-C levels were comparable to those of controls. Sd-LDL-C levels were positively correlated with TG, LDL C, and apolipoprotein B, and were inversely with HDL-C. Sd-LDL-C levels were also correlated positively with waist circumference, blood pressure, and insulin resistance index, and negatively with adiponectin level. Patients with type 2 diabetes and metabolic syndrome had substantially increased sd-LDL-C level. These results suggest that measurement of sdLDL-C is useful to evaluate overall atherogenic risks associated with metabolic syndrome and may be applicable to routine clinical examination.

The relationship of cholesterol (CHO) and triglycerides (TG) in VLDL,LDL, and VLDL subfractions by agarose gel electrophoresis,using CHO and TG dual staining (AG-CHO,TG staining)

The measurement of CHO and TG concentrations in three lipoprotein subfractions (VLDL, LDL, and HDL) are useful to estimate qualitative change of lipoproteins. This method, CHO and TG dual staining using agarose gel electrophoresis (AG-CHO, TG staining), is conventional and the results correlated highly with ultracentrifugation. Using this method, we measured CHO and TG concentrations of VLDL, LDL, and HDL subfractions in 244 patients after an overnight fast. All cases were stratified to 4 groups, normolipidemia (LDL-CHO < 160 mg/dl, sTG < 150 mg/dl, n = 111), type IIa(n = 34), IIb(n = 39), and IV(n = 36), according to hyperlipidemia types. Furthermore, normolipidemia with low HDL cases (HDL-CHO < 45 mg/dl, n = 24) distinguished from HDL-CHO > or = 45 mg/dl, normolipidemia cases(n = 111). Between serum TCHO and LDL-CHO, serum TG and VLDL-CHO, TG showed positive correlation(n = 0.895, 0.971), particularly serum TG and VLDL-TG showed strong positive in all lipidemia types. However, serum TG and VLDL-CHO was strongly positive in type IIb and IV(r = 0.825, 0.823), but weakly positive in type IIa(r = 0.459). HDL-CHO showed no correlation with sTCHO and sTG. The correlation of CHO and TG with each subfraction was strongly positive in VLDL(r = 0.910), weakly positive(r = 0.49) in LDL, and showed the no correlation in HDL in all cases. These correlation varied in lipidemia types, IIb and IV were strongly positive(r = 0.886, 0.838) in VLDL subfraction, but nomolipidemia cases(r = 0.555) showed significant weaker correlation(p < 0.0001). In the LDL subfraction, IIb and IV showed no correlation(r = 0.009, 0.163) between CHO and TG. The CHO/TG ratio of three subfractions were widely distributed, and type IIb and IV distributed to lower range than normolipidemia and/or type IIa lipidemia in three subfractions. From these results, dual measurement of LDL-CHO and LDL-TG are useful to estimate qualitative change in the LDL subfraction. For instance, in high LDL-CHO or LDL-TG with low CHO/TG cases, we could suspect the presence of IDL-rich particles in the LDL subfraction or small particle LDL cases. HDL-CHO and CHO/TG show positive(r = 0.714), HDL-CHO and VLDL-TG, VLDL-CHO showed weakly negative correlations(r = 0.500, 0.487), showing that high HDL-CHO level cases tended to have a CHO rich, and low VLDL-TG concentration. These results indicated that qualitative change in lipoproteins could be clarified by measurement of the TG concentration, in addition to CHO concentrations in three subfractions. We conclude that AG-CHO, TG staining method is useful for diagnosis and monitoring of dyslipidemia.
