[PMID: 34312083 DOI: 10.1016/j.jacl.2021.06.005] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/15/2020] [Revised: 05/14/2021] [Accepted: 06/26/2021] [Indexed: 12/23/2022]
Abstract
BACKGROUND The association between non-high-density lipoprotein cholesterol (non-HDL-C) and mortality in patients undergoing peritoneal dialysis (PD) is unclear. OBJECTIVE The aim of this study was to evaluate the association of non-HDL-C with cardiovascular (CV) and all-cause mortality in PD patients. METHODS We conducted a prospective cohort study. A total of 1,616 incident PD patients from a single PD center in South China were followed for a median of 47.6 months. The independent association of non-HDL-C with CV and all-cause mortality was evaluated by a Cox regression analysis. RESULTS During the follow-up period, 508 (31.4%) patients died, of which 249 (49.0%) were due to CV events. Atherosclerotic CV mortality accounted for 59.8% of CV mortality. In multivariable models, for 1-SD increase in non-HDL-C level, the hazard ratios (HRs) for CV and all-cause mortality were 1.52 [95% confidence interval (CI), 1.32-1.75; P < 0.001)] and 1.24 (95% CI, 1.12-1.39; P < 0.001), respectively. Furthermore, non-HDL-C was positively associated with atherosclerotic CV mortality (HR, 1.29; 95% CI, 1.09-1.52; P = 0.004) but not associated with nonatherosclerotic CV mortality (HR, 0.79; 95% CI, 0.59-1.05; P = 0.108). The quartile analyses showed a similar pattern to the continuous variable analyses of non-HDL-C levels for CV and all-cause mortality but did not demonstrate statistical significance for atherosclerotic or nonatherosclerotic CV mortality. CONCLUSION An elevated non-HDL-C level was independently associated with an increased risk of CV mortality, especially atherosclerotic CV mortality, and all-cause mortality in incident PD patients.

Abstract
BACKGROUND Low-density lipoprotein (LDL) is atherogenic and LDL particles are reduced in diameter in the presence of insulin resistance, forming small, dense LDL. This study was conducted to assess the relationship between commonly used lipid indices and LDL particle size and furthermore to clarify the best surrogate lipid markers that could conveniently be used to estimate LDL particle size in children. METHODS We determined LDL particle diameter by gradient gel electrophoresis in 1578 children aged 10-12 years. At the fasting state, the relationships between measured LDL particle size and lipid variables [total cholesterol (TC), triglycerides (TG), LDL-cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), atherogenic index [(TC-HDL-C)/HDL-C, TG/HDL-C, LDL-C/HDL-C, and LDL-C/apolipoprotein B (Apo B) and non-HDL-C (TC-HDL-C)] were analyzed. RESULTS The LDL particle diameter was 26.64 (mean) ± 0.48 (SD) nm in boys (n = 820) and 26.66 ± 0.49 nm in girls (n = 758); there was not a statistically significant difference. There were statistically significant correlations between LDL particle size and TG or HDL-C concentrations (r = 0.28∼0.37), but the correlations with LDL-C and ApoB were very weak. The combined lipid measures, such as atherogenic index, TC/HDL-C, TG/HDL-C, and LDL-C/HDL-C showed moderate correlations (r = 0.33∼0.38) with LDL particle size; however, the correlation of non-HDL-C with LDL particle size was weak (r = 0.18∼0.19). Simple HDL-C measure appeared to be of comparable value to combined lipid measures. CONCLUSIONS Our data indicate that various lipid indices are not superior to HDL-C levels alone as a clinical tool for estimating LDL particle size. Non-HDL-C was less valuable in this aspect.

J Ren Nutr 2011; 22:251-257.

Abstract
INTRODUCTION Non-high-density lipoprotein cholesterol (non-HDL-c) may be a better indicator of atherogenicity in the hemodialysis population. PURPOSE To investigate the correlation of non-HDL-c with anthropometric measurements associated to cardiovascular risk, such as body mass index, waist circumference, waist-to-height ratio, waist-to-height(2) ratio, and waist-to-hip circumference ratio. METHODS We evaluated anthropometric markers and lipids in 86 hemodialysis patients, and the correlation between them was investigated. RESULTS Non-HDL-c had a positive correlation with body mass index (r = 0.273; P = .01), waist circumference (r = 0.375; P = .000), waist-to-height ratio (r = 0.333; P = .002), waist-to-height(2) ratio (r = 0.270; P = .012), and waist-to-hip circumference ratio (r = 0.356; P = .001). CONCLUSIONS This study detected a positive and significant correlation between non-HDL-c, but not low-density lipoprotein cholesterol, and the anthropometric cardiovascular risk indexes. We could suggest that non-HDL-c can be used as a cardiovascular risk factor indicator among dialysis patients.

Abstract
The National Cholesterol Education Programme Adult Treatment Panel III accepted the predominance of small dense low-density lipoprotein (sdLDL) as an emerging cardiovascular disease (CVD) risk factor. Most studies suggest that measuring low-density lipoprotein (LDL) particle size, sdLDL cholesterol content and LDL particle number provides additional assessment of CVD risk. Therapeutic modulation of small LDL size, number and distribution may decrease CVD risk; however, no definitive causal relationship is established, probably due to the close association between sdLDL and triglycerides and other risk factors (e.g., high-density lipoprotein, insulin resistance and diabetes). This review addresses the formation and measurement of sdLDL, as well as the relationship between sdLDL particles and CVD. The effect of hypolipidaemic (statins, fibrates and ezetimibe) and hypoglycaemic (glitazones) agents on LDL size and distribution is also discussed.

Abstract
Patients undergoing chronic renal replacement therapy have a high incidence of dyslipidemia. In general, there are increased concentrations of triglyceride-rich apolipoprotein B-containing particles. These elevations lead to increased levels of non-high-density lipoprotein (HDL) levels. This pattern is further modified by the method of dialysis (peritoneal versus hemodialysis) and comorbidities such as diabetes. End-stage renal disease patients also demonstrate increased levels of lipoprotein(a) (Lp(a)) and oxidized low-density lipoprotein (LDL)both of which are highly atherogenic. This review focuses on the pathogenesis of these lipid abnormalities and their role in the atherosclerotic process.

Abstract
Cardiac disease is the leading cause of death in patients having end-stage renal disease (ESRD). Patients with ESRD have a higher risk for developing coronary artery disease (CAD) than one would estimate from the presence of traditional risk factors such as hypertension, diabetes, hyperlipidemia, and cigarette smoking. Patients with milder forms of renal dysfunction who do not require dialysis also appear to have an increased risk for CAD. ESRD is associated with anemia, hyperhomocystinemia, increased calcium-phosphate product, hypoalbuminemia, increased troponin, increased markers of inflammation, increased oxidant stress, and decreased nitric oxide activity, factors that could contribute to increased CAD risk. Patients with ESRD require aggressive management of traditional risk factors for CAD, which include hypertension, hyperlipidemia, hyperhomocystinemia, and hypercoagulability. Milder forms of renal dysfunction could also be predictors of occult CAD and should be screened for in assessing cardiac risk in asymptomatic individuals.
