Abstract High-density lipoprotein (HDL) subclasses have different antiatherogenic potentials and functional properties. This work presents our findings and discussions on their metabolic implications on apolipoprotein (apo) C-III together with other apolipoprotein levels and HDL subclass distribution profile. Apolipoprotein A-I contents of plasma HDL subclasses were quantitated by 2-dimensional gel electrophoresis coupled with immunodetection in 511 subjects. Concentrations of triglycerides and ...
Triglyceride-rich lipoprotein (TGRL) lipolysis products provide a pro-inflammatory stimulus that can alter endothelial barrier function. To probe the mechanism of this lipolysis-induced event, we evaluated the pro-inflammatory potential of lipid classes derived from human postprandial TGRL by lipoprotein lipase (LpL). Incubation of TGRL with LpL for 30 min increased the saturated and unsaturated FFA content of the incubation solutions significantly. Furthermore, concentrations of the hydroxylate...
Abstract Preβ1-HDL, a putative discoid-shaped high-density lipoprotein (HDL) is known to participate in the retrieval of cholesterol from peripheral tissues. In this study, to clarify potential sources of this lipoprotein, we conducted heparin injection on four Japanese volunteer men and found that serum triglyceride (TG) level decreased in parallel with the increase in serum nonesterified fatty acids and plasma lipoprotein lipase (LPL) protein mass after heparin injection. Plasma preβ1-HDL show...
Background: High-density lipoprotein (HDL) cholesterol levels are inversely related to risk for coronary artery disease (CAD). Because HDL particles are heterogeneous in size and composition, they may be differentially associated with other cardiovascular risk factors and with cardiovascular risk. Objective: To study the independent relationships of HDL size and particle concentration to risk for future CAD. Design: Nested case-control study within the EPIC (European Prospective Investigation in...
Abstract Objective To investigate the risk factors of insulin resistance (IR) and the role of IR and metabolic syndrome in the pathogenesis of chronic allograft nephropathy (CAN). Methods One hundred and twenty-seven kidney transplant recipients with normal renal function and no proteinuria at the 6th month after transplantation, and without the experience of acute rejection, calcinurine intoxication and severe infection, were involved in the study. Their primary disease of ESRF was chronic glom...
Background. Patients with diabetes have been reported to have greater dyslipidemia after kidney transplant (KTX). Because postKTX management of diabetes has changed markedly since those reports, we hypothesized that lipids can be controlled as well in diabetic as in nondiabetic recipients. Methods. We compared lipid levels up to 2 years after KTX ( n= 192) between diabetic and nondiabetic recipients. The cohort was subdivided into nondiabetic (nonDM-K; n=123), type 2 (DM2-K; n=33), or type 1 dia...

The concurrence of visceral obesity, insulin resistance and dyslipidaemia comprises the concept of the metabolic syndrome. The metabolic syndrome is an escalating problem in developed and developing societies that tracks with the obesity epidemic. Dyslipidaemia in the metabolic syndrome is potently atherogenic and, hence, is a major risk factor for CVD (cardiovascular disease) in these subjects. It is globally characterized by hypertriglyceridaemia, near normal LDL (low-density lipoprotein)-chol...
Abstract Background To analyze the relationship between plasma apoB100 concentrations, apoB100/apoA-I ratio and the alteration of HDL subclasses distribution. Methods The apoA-I contents of plasma HDL subclasses were quantitated by 2-dimensional gel electrophoresis coupled with immunodetection in 506 subjects. Results The subjects in the highest tertile of apoB100 groups had significantly higher small-sized preβ1–HDL, however lower large-sized HDL2a, HDL2b than the subjects in the lowest tertile...

Summary Background: Hypertriglyceridaemia, commonly found in subjects with obesity and type 2 diabetes mellitus, is associated with increased risk of coronary heart disease (CHD). Apolipoprotein C-III (apoC-III) plays an important role in regulating the metabolism of triglyceride-rich lipoproteins (TRLs) and may provide a new approach to assessing hypertriglyceridaemia. Aims: We review the role of apoC-III in regulating TRL metabolism and address the potential importance of apoC-III in clinical ...

Background Dyslipidemia is common in kidney transplant (KT) recipients. We analyzed the ratio of triglyceride to high-density lipoprotein cholesterol (TG/HDL-C) in KT recipients to identify risk factors for major cardiovascular events (MACE).
Abstract Dates are delicious fruits with a sweet taste and a fleshy consistency. Dates also have various bioactive components which have effects on different types of diseases. The objective of this study was to determine the effects of date vinegar made from date pulp and pits on the serum lipid profile and inflammatory biomarkers of mildly hypercholesterolemic adults. Seventy-six subjects with mildly raised total cholesterol and LDL cholesterol were enrolled. Participants ingested 30 mL of eit...

Background Immunosuppressive medications often cause posttransplant hyperlipidemia. The effects of cyclosporine (CsA) and tacrolimus (Tac) on lipid profile is well-known; however, there are very few studies related to the effect of these immunosuppressants on fatty acids (FA) of phosholipids fraction (PL) in renal transplant recipients (RTR). We sought to analyze the FA profile in PL fraction of RTR treated with Tac or CsA. Methods The study included 65 renal transplant patients on CsA (n = 24, ...
Background Since chronic apical periodontitis (CAP) appears to be a risk factor for coronary heart disease, the aim of the study was to determine the relationship between the size of CAP lesion and inflammatory markers (hsCRP, IL-6, TNF-α), as well as lipids and lipoproteins (LpPLA2, apoAI, apoB level) in blood serum of patients with CAP.

Patients with kidney diseases continue to experience significant cardiovascular disease (CVD) morbidity and mortality. Although there are many important risk factors playing a role in the pathogenesis of CVD in chronic kidney disease (CKD) patients, dyslipidemia (elevated triglycerides, elevated oxidized low-density lipoprotein and low/dysfunctional low high-density) represents one of the modifiable risk factors. Renal failure patients have unique lipid abnormalities which not only have complex ...
High-density lipoprotein cholesterol (HDL-C) and apolipoprotein A-I (apoA-I) levels are inversely associated with adverse cardiovascular outcomes. Associations between these HDL-C–related measurements and coronary plaque progression have not been studied. We performed a retrospective analysis of 2,566 statin-treated patients with angiographic coronary artery disease who underwent serial evaluation of atheroma burden with intravascular ultrasound. Relations between achieved levels of HDL-related ...

Background: HDL size and composition vary among individuals and may be associated with cardiovascular disease and diabetes. We investigated the theoretical relationship between HDL size and composition using an updated version of the spherical model of lipoprotein structure proposed by Shen et al. ( Proc Natl Acad Sci U S A 1997;74:837–41.) and compared its predictions with experimental data from the Women's Health Study (WHS). Methods: The Shen model was updated to predict the relationship betw...
