Background and rationale: HDL cholesterol is one of the 5 major groups of lipoproteins cholesterol, which enable lipids like cholesterol and TG to be transported within the water based blood stream. In healthy persons, about thirty percent of blood cholesterol is carried by HDL cholesterol. HDL-C is a potent predictor of coronary heart disease. Genetic as well as environmental factors including lifestyle factors play a role as determinants of its level in the blood. To examine the effects of certain lifestyle factors on serum level of high density lipoprotein cholesterol in young adult people HDL cholesterol seems to protect against CVD which increases the risk for heart disease.Subjects and methods: Three hundred and twenty five young adult subjects of both sexes aged 18-45 years asymptomatic for cardiovascular diseases were interviewed according to special questionnaire including information on lifestyle habits. Physical examination was done, height, body weight, and blood pressure measurements were performed. Blood analysis to determine the blood level of high density lipoprotein cholesterol was done after 12 hours fasting.Results and conclusion: Smoking and obesity were the most significant risk factors associated with a decreased level of high density lipoprotein cholesterol. The level of HDL-C was 50.5±11.5 mg/dl in smokers compared with 57.7±12.5 mg/dl in nonsmokers. Its level was 48.5 ±8.5 mg/dl in obese individuals compared to 57.5±11.7mg/dl in normal body weight subjects. Physical activity was not significantly associated with low level of HDL-C analysis, but it was found to be significantly associated with its level by the multiple regression analysis. High-density lipoprotein cholesterol level was a function of many factors, some of them were lifestyle related such as smoking, physical activity, and obesity. Therefore, efforts to encourage more physical activity, quitting smoking, consuming low fat diet, and keeping ideal body weight are recommended.Bangladesh Journal of Medical Science Vol.16(2) 2017 p.289-294

Over the years, the relationship between high-density lipoprotein (HDL) and atherosclerosis, initially highlighted by the Framingham study, has been revealed to be extremely complex, due to the multiple HDL functions involved in atheroprotection. Among them, HDL cholesterol efflux capacity (CEC), the ability of HDL to promote cell cholesterol efflux from cells, has emerged as a better predictor of cardiovascular (CV) risk compared to merely plasma HDL-cholesterol (HDL-C) levels. HDL CEC is impaired in many genetic and pathological conditions associated to high CV risk such as dyslipidemia, chronic kidney disease, diabetes, inflammatory and autoimmune diseases, endocrine disorders, etc. The present review describes the current knowledge on HDL CEC modifications in these conditions, focusing on the most recent human studies and on genetic and pathophysiologic aspects. In addition, the most relevant strategies possibly modulating HDL CEC, including lifestyle modifications, as well as nutraceutical and pharmacological interventions, will be discussed. The objective of this review is to help understanding whether, from the current evidence, HDL CEC may be considered as a valid biomarker of CV risk and a potential pharmacological target for novel therapeutic approaches.

Objective: Elevated uric acid (UA) and low levels of high-density lipoprotein (HDL) cholesterol are associated with cardiovascular events and mortality. Erectile dysfunction (ED) has been considered an early marker of cardiovascular disease (CVD). Therefore, this study aimed to investigate the uric acid/ HDL ratio (UHR) as a nowel marker in patients with ED. Materials and Methods: The study included 147 patients with a mean age of 50 years (range 32-76 years). Retrospective analyses were performed on the patients who were admitted to urology outpatient clinics. The laboratory parameter results were retrieved from the hospital medical records, and the UHR value was calculated. Patients were categorized into three groups according to the International Index of Erectile Function (IIEF) score. UHR was compared between groups, and its predictive value was evaluated using regression analysis and ROC curve analysis. Results: Age was found to be significantly different in all three groups (Groups 1-2, p=0.001; Groups 1-3, p=0.000; Groups 2-3, p=0.001). It was observed that the degree of ED increased with age. The values of UA and HDL were similar in all groups (p>0.05). In contrast, the UHR value was statistically significantly higher 0.15 (0.083-0.288, p =0.047) in the moderate-severe ED (Group 3). ROC curve analyses revealed that UHR predicted severe ED (IIEF 5-11) with 42.9% sensitivity and 87.3% specificity (AUC:0.66, CI 95% 0.538-0.781, p=0.019). Conclusion: UHR may serve as a severe ED indicator in patients admitted to the cardiology outpatient clinic since it has a significant association with a low IIEF score.

Background: Dyslipidemia, a genetic and multifactorial disorder of lipoprotein metabolism, is defined by elevations in levels of total cholesterol, low-density lipoprotein cholesterol (LDL-C), non-high-density lipoprotein cholesterol (non–HDL-C), triglyceride, or some combination thereof, as well as lower levels of high-density lipoprotein (HDL) cholesterol. Objectives: This study aimed to investigate the prevalence and predictors of dyslipidemia in children and adolescents in the Yazd Greater Area, Yazd, Iran. Methods: This cross-sectional study was conducted as a part of the national project implemented in Yazd Greater Area, Yazd, Iran. The sampling was performed using a multi-stage cluster sampling method on three age groups of girls and boys (6-9, 10-14, and 15-18 years old). Out of the total 1,035 children and adolescents who participated in this study, only 784 participants remained in the study until the end. Data collection was performed using lifestyle questionnaires including Kiddie-SADS-Present and Lifetime Version. Results: The prevalence of high triglyceride was estimated at 1.4% and 4.2% in 6-9 and 10-18 years old children and adolescents, respectively. The prevalence of high cholesterol, LDL, and HDL was 3.2%, 3.2%, and 25.6%, respectively. The prevalence of dyslipidemia in the total population of children and adolescents in terms of demographic variables was 64.6% and 57.3% in boys and girls, respectively (P=0.038). Gender and increase in body mass index were significantly associated with dyslipidemia with OR=1.35; 95% CI: 1.01-1.81 and OR=13.781; 95% CI: 3.78- 46.43, respectively. However, after adjustment for other factors, only an increase in BMI was significantly associated with dyslipidemia (OR=16.08; 95% CI: 4.49-57.59). Conclusions: Overweight and obese adolescents had a higher concentration of serum blood triglycerides, compared to other adolescents. Weight control, lifestyle modification, and diet are three ways to reduce lipid disorders in adolescents.

Objective: Acute coronary syndrome is frequently complicated by rhythm disturbances, yet any association between high-density lipoprotein (HDL) cholesterol levels and arrhythmias in the setting of non-ST-segment elevation myocardial infarction (non-STEMI) is uncertain. The goal of this study was to evaluate any association between HDL-cholesterol levels and arrhythmias in the setting of non-STEMI. Methods: Retrospective data from Phoenix Veterans Affair Medical Center records were utilized for our study. A total of 6881 patients were found who presented during 2000 to 2003 with non-STEMI with available fasting lipid panels collected within the first 24 hours of admission. Patients were followed for the development of rhythm disturbances up to 6 years after initial presentation, with a mean follow up of 1269 days. Results: We found that high triglycerides/HDL and low-density lipid/HDL ratios were predictive of arrhythmias. However, low HDL levels had strongest association with highest odds ratio (OR) for development of arrhythmias (for HDL <31 mg/dL, OR = 3.72, 95% confidence interval [CI] = 2.55-5.44, P < .05) in patients with diabetes and (for HDL < 31 mg/dL, OR = 3.69, 95% CI = 2.85-4.71, P < .05) in patients without diabetes. Using multivariate analysis adjusting for comorbidities, low HDL level remained independently associated with arrhythmias. Conclusions: Patients with low HDL levels during hospitalization with non-STEMI have a greater risk of developing cardiac rhythm disturbances independent of other risk factors. These data suggest a possible protective role of HDL in preventing arrhythmias in the setting of acute coronary syndrome.

BACKGROUND: Few studies have examined prospectively the relationship between baseline high-density lipoprotein (HDL) cholesterol and longevity. OBJECTIVES: We sought to examine whether higher HDL levels were associated with lower risk of all-cause, cardiovascular (CVD), and non-CVD mortality prior to age 90 in the Physicians’ Health Study (PHS). METHODS: We considered a baseline cohort of 1351 PHS participants who provided bloods between 1997 and 2001 and were old enough to reach age 90 by March 4, 2009. Included subjects had complete baseline data on HDL and total cholesterol; lifestyle factors including smoking, exercise, alcohol consumption, and BMI; and comorbidities including hypertension, diabetes mellitus, congestive heart failure, cancer, and stroke. We used Cox proportional hazards to determine the HRs and 95% CIs for all-cause, CVD, and non-CVD mortality prior to age 90, adjusting for baseline age, co-morbidities, and non-HDL cholesterol. RESULTS: At baseline, the cohort had a mean (SD) age of 81.9 (2.9) years and a mean (SD) HDL cholesterol of 44.8(16.5) mg/dL. After a mean follow-up of 6.8 years (maximum 12.3 years), 501 (37.1%) of men died prior to age 90. In multi-variable adjusted analyses, men in the highest HDL-C quartile (≥54.1 mg/dL) had a 28% lower risk (HR 0.72, 95% CI 0.55-0.95) of all-cause mortality prior to age 90 compared to men in the lowest HDL-C quartile (<32.8 mg/dL). From the lowest to highest HDL quartile, age-adjusted HR(95%CI) for CVD mortality prior to age 90 were 0.66 (0.44-0.99), 0.58 (0.38-0.90), and 0.53 (0.34-0.82) (p for trend 0.004). There was no significant association between baseline HDL cholesterol and non-CVD death. CONCLUSION: In a cohort of older male physicians with long-term follow-up, baseline HDL cholesterol was inversely associated with the risk of dying prior to age 90, largely explained by an inverse association between HDL and CVD mortality.

Abstract We evaluated the performance of two homogeneous assays for quantifying HDL cholesterol (HDL-C) and compared them with the phosphotungstic acid (PTA)/MgCl2 assay. Both homogeneous HDL-C assays were precise, having a within-run CV of &lt;1.20% and a between-run CV of &lt;4.07%. The HDL-C values (y) measured by the two homogeneous methods correlated well with those by the PTA/MgCl2 method (x): y = 1.00x + 64.98 mg/L, r = 0.987, Sy|x = 27.99 mg/L (n = 152) for the polyethylene glycol-modified enzymes/α-cyclodextrin sulfate (PEGME) assay (Kyowa), and y = 0.84x + 106.51 mg/L, r = 0.984, Sy|x = 26.10 mg/L (n = 152) for the polyanion–polymer/detergent (PPD) assay (Daiichi). The specificity of the PEGME method seemed better than that of the PPD method, as the PPD method was markedly interfered with by supplemental LDL-C. Addition of 20 g/L triglycerides produced a negative error of ∼18% in both homogeneous assays. Bilirubin and hemoglobin had little influence on the PEGME method; hemoglobin had little effect on the PPD method. Bilirubin, however, markedly decreased the readings by the PPD method. We found the PEGME assay superior to the PPD assay for routine HDL-C testing, because the PPD assay is relatively inaccurate and not specific.
