Dyslipidemia is an important modifi able risk factor for cardiovascular and metabolic diseases, which are responsible for a large number of mortality and disability cases around the globe. Different strategies have been used within the treatment of dyslipidemia, including lifestyle modifi cations, pharmacologic therapy, as well as functional foods and nutraceuticals. Functional foods have been used worldwide since ancient times, particularly, the prehispanic civilizations utilized several as medicinal foods. In the current pandemic of dyslipidemia as well as the nutritional transition, particularly in Latin America, the use of native functional foods represents an attractive target for the treatment and/ or prevention of these conditions. In this mini-review, evidence regarding different functional foods such as cacao, amaranth, chia, nopal, spirulina, as well as their nutraceutical compounds, including fl avonoids, omega-3 PUFAs, fi ber, prebiotics, lovastatin, c-phycocyanin, among others, and their mechanism of action are presented and discussed. Although such foods certainly are considered as attractive potential agents to target dyslipidemia thus decrease the associated cardiometabolic risk, we conclude that for most of the presented functional foods there is currently not enough evidence to support its recommendation and every-day use.

Diabetes and dyslipidemia are commonly associated modifiable risk factors for cardiovascular diseases. Majority of patients with diabetes also suffer from dyslipidemia (diabetic dyslipidemia). Diabetic dyslipidemia is more atherogenic as it is commonly associated with high triglyceride (TG) levels, high proportion of small dense low-density lipoprotein cholesterol and low high-density lipoprotein cholesterol (HDL-C) level (atherogenic dyslipidemia). Currently used pharmacotherapies for the management of diabetes and dyslipidemia like thiazolidinediones (PPAR-γ agonist; for insulin resistance) and fibrates (PPAR-α agonist; for hypertriglyceridemia) have many limitations and side effects. Saroglitazar , a dual PPAR-α/γ agonists, is an emerging therapeutic option with its dual benefit on glycemic and lipid parameters. This paper reviews the clinical development of saroglitazar for the management of diabetic dyslipidemia. The efficacy and safety profile of saroglitazar is reviewed in context to currently available therapy like pioglitazone for diabetes and fibrates for hypertriglyceridemia. In addition, this paper also reviews the association between diabetes and dyslipidemia and the role of TG in reducing cardiovascular events. Saroglitazar, a dual PPAR-α/γ agonist, is a potential therapeutic option for the management of diabetic dyslipidemia. It has dual benefit of significant improvement in glycemic parameters (glycated hemoglobin and fasting blood glucose) and significant improvement in dyslipidemia (TGs, apolipoprotein B, non-HDL-C). The results of Phase III clinical trials indicate that saroglitazar is devoid of conventional side effects of fibrates and pioglitazone. Future clinical trials of saroglitazar will further establish its place in the management of diabetes, dyslipidemia and associated cardiovascular risk.

The relationship between dyslipidemia and hearing is unclear. This study was conducted to investigate whether elevated serum lipid levels impact auditory function in humans and in guinea pigs. In the human study, a cross-sectional study of 40 volunteers with dyslipidemia was conducted. Pure tone thresholds, distortion product otoacoustic emissions, and lipid profiles were analyzed. When controlled for patient age and sex, we found that elevated triglycerides were associated with reduced hearing. In the guinea pig study, a prospective study of animals fed a high-fat diet for 14 weeks was conducted. Although the high-fat diet led to a dramatic elevation in the average weight and total cholesterol in all animals (from 61 to 589 mg/dl), there were no meaningful changes in distortion product otoacoustic emission magnitudes. These results suggest that whereas chronic dyslipidemia associated with elevated triglycerides may reduce auditory function, short-term dietary changes may not. PMID:16868509

Dyslipidemia is a major risk factor of cardiovascular disease. The aim of this study was to investigate the changing trends in the prevalence and management status of dyslipidemia among Korean adults. The prevalence of dyslipidemia and the rates of awareness, treatment, and control of dyslipidemia were investigated in adults aged ≥20 years from the Korea National Health and Nutrition Surveys (KNHANES) 1998 to 2010. The updated National Cholesterol Education Program criteria was used, which define dyslipidemia as having one or more of the following lipid abnormalities: hypercholesterolemia (total cholesterol ≥240 mg/dL or diagnosis of dyslipidemia or use of lipid-lowering drugs), hypertriglyceridemia (≥150 mg/dL), hyper-low density lipoprotein (LDL) cholesterolemia (≥160 mg/dL or diagnosis of dyslipidemia or use of lipid-lowering drugs), and hypo-high density lipoprotein (HDL)-cholesterolemia (<40 mg/dL in men and <50 mg/dL in women). The number of participants was 6,921, 4,894, 5,312, 2,733, 6,295, 6,900, and 5,738 in KNHANES 1998, 2001, 2005, 2007, 2008, 2009, and 2010, respectively. Age-standardized prevalence rates of dyslipidemia were 54.0%, 65.8%, 66.5%, 60.6%, 58.7%, 58.9%, and 59.0% in 1998, 2001, 2005, 2007, 2008, 2009, and 2010, respectively. Hypertriglyceridemia and hypo-HDL-cholesterolemia were the two most frequent lipid abnormalities. The overall prevalence of hypercholesterolemia and hyper-LDL-cholesterolemia increased by 1.36- and 1.35-fold in 2010 compared with 2007, respectively. Awareness, treatment, and control rates of dyslipidemia improved over the period of surveys in both sexes. In 2010, about 30% of dyslipidemic patients who received lipid-lowering treatment reached target levels. Although the management status of dyslipidemia has improved during recent years, effective strategy is required for achieving better prevention, treatment, and control of dyslipidemia.

Genetic dyslipidemias contribute to the prevalence of ischemic heart disease. The field of genetic dyslipidemias and their influence on atherosclerotic heart disease is rapidly developing and accumulating increasing evidence. The purpose of this review is to describe the current state of knowledge in regard to inherited atherogenic dyslipidemias. The disorders of familial hypercholesterolemia (FH) and elevated lipoprotein(a) will be detailed. Genetic technology has made rapid advancements, leading to new discoveries in inherited atherogenic dyslipidemias, which will be explored in this review, as well as a description of possible future developments. Increasing attention has come upon the genetic disorders of familial hypercholesterolemia and elevated lipoprotein(a). This review includes new knowledge of these disorders including description of these disorders, their method of diagnosis, their prevalence, their genetic underpinnings, and their effect on the development of cardiovascular disease. In addition, it discusses major advances in genetic technology, including the completion of the human genome sequence, next-generation sequencing, and genome-wide association studies. Also discussed are rare variant studies with specific genetic mechanisms involved in inherited dyslipidemias, such as in the proprotein convertase subtilisin/kexin type 9 (PCSK9) enzyme. The field of genetics of dyslipidemia and cardiovascular disease is rapidly growing, which will result in a bright future of novel mechanisms of action and new therapeutics.

Despite achieving targets for low-density lipoprotein (LDL) cholesterol, blood pressure, and glycemia in accordance with current standards of care, patients with dyslipidemia remain at high residual risk of vascular events. Atherogenic dyslipidemia, characterized by elevated triglycerides and low levels of high-density lipoprotein (HDL) cholesterol, often with elevated apolipoprotein B and non-HDL cholesterol, is common in patients with established cardiovascular disease (CVD), type 2 diabetes mellitus, or metabolic syndrome and contributes to both macrovascular and microvascular residual risk. However, atherogenic dyslipidemia is largely underdiagnosed and undertreated in clinical practice. The Residual Risk Reduction Initiative (R3i) was established to address this highly relevant clinical issue. The aims of this position paper are (1) to highlight evidence that atherogenic dyslipidemia is associated with residual macrovascular and microvascular risk in patients at high risk for CVD, despite current standards of care for dyslipidemia and diabetes; and (2) to recommend therapeutic intervention for reducing this residual vascular risk supported by evidence and expert consensus. Lifestyle modification with nutrition and exercise is an important, effective, and underutilized first step in reducing residual vascular risk. Therapeutic intervention aimed at achievement of all lipid targets is also often required. Combination lipid-modifying therapy, with the addition of niacin, a fibrate, or omega-3 fatty acids to statin therapy, increases the probability of achieving all lipid goals. Outcomes studies are in progress to evaluate whether these combination treatment strategies translate to a clinical benefit greater than that achieved with statins alone. The R3i highlights the need to address with lifestyle and/or pharmacotherapy the high level of residual risk of CVD events and microvascular complications among patients with dyslipidemia receiving therapy for high levels

Natriuretic peptides have been associated with dyslipidemia. As a physiological activator of natriuretic peptides, corin might also be associated with dyslipidemia. However, this association has not yet been studied in Chinese populations. Serum soluble corin and blood lipid profiles were determined for 2496 participants aged above 30y. A logistic regression model was applied to evaluate the association between serum soluble corin and dyslipidemia. Serum soluble corin was significantly increased in participants with dyslipidemia in both men (P<0.001) and women (P<0.001). After controlling for the confounding factors, OR of dyslipidemia positively increased with increasing levels of serum soluble corin in men (P for trend=0.011) and women (P for trend=0.043). Participants with a high corin level were more likely to have dyslipidemia than those with a low corin level in men (OR, 95% CI: 1.45, 1.07-1.97) and women (OR, 95% CI: 1.33, 1.04-1.70). Serum soluble corin was significantly and positively associated with dyslipidemia. Our findings suggested that serum soluble corin may be a marker or risk factor for dyslipidemia.

Among traditional atherosclerotic risk factors, dyslipidemia is believed to decisively affect the long-term prognosis of lupus patients, not only with regard to cardiovascular events but also by influencing other manifestations, such as lupus nephritis. The aim of this study was to review the epidemiology, pathogenesis, evidence for its impact on atherosclerosis manifestations and management of dyslipidemia in lupus patients. English-restricted MEDLINE database search (Medical Subject Headings: lupus or systemic lupus erythematosus and dyslipidemia or hyperlipidemia). The prevalence of dyslipidemia in systemic lupus erythematosus (SLE) ranges from 36% at diagnosis to 60% or even higher after 3 years, depending on definition. Multiple pathogenetic mechanisms are implicated, including antibodies against lipoprotein lipase and cytokines affecting the balance between pro- and anti-atherogenic lipoproteins. Dyslipidemia has a clear impact on clinical cardiovascular disease and surrogate markers for subclinical atherosclerosis. Moreover, it negatively affects end-organ damage (kidneys and brain). Treatment with statins yielded contradictory results as per minimizing cardiovascular risk. Dyslipidemia is a significant comorbidity of lupus patients with multiple negative effects in the long term. Its treatment represents a modifiable risk factor; prompt and adequate treatment can minimize unnecessary burden in lupus patients, thus reducing hospitalizations and their overall morbidity and mortality.

Polygenic influences on dyslipidemias.

PubMed

Dron, Jacqueline S; Hegele, Robert A

2018-04-01

Rare large-effect genetic variants underlie monogenic dyslipidemias, whereas common small-effect genetic variants - single nucleotide polymorphisms (SNPs) - have modest influences on lipid traits. Over the past decade, these small-effect SNPs have been shown to cumulatively exert consistent effects on lipid phenotypes under a polygenic framework, which is the focus of this review. Several groups have reported polygenic risk scores assembled from lipid-associated SNPs, and have applied them to their respective phenotypes. For lipid traits in the normal population distribution, polygenic effects quantified by a score that integrates several common polymorphisms account for about 20-30% of genetic variation. Among individuals at the extremes of the distribution, that is, those with clinical dyslipidemia, the polygenic component includes both rare variants with large effects and common polymorphisms: depending on the trait, 20-50% of susceptibility can be accounted for by this assortment of genetic variants. Accounting for polygenic effects increases the numbers of dyslipidemic individuals who can be explained genetically, but a substantial proportion of susceptibility remains unexplained. Whether documenting the polygenic basis of dyslipidemia will affect outcomes in clinical trials or prospective observational studies remains to be determined.

Dyslipidemia, a strong predictor of cardiovascular diseases, is prevalent among Korean adults, but little is known about the associations between overall lipid profiles and dietary factors. We identified dyslipidemia patterns among lipid indicators and examined dietary factors associated with dyslipidemia patterns in Korean adults. Subjects in this cross-sectional study were recruited from the Family Medicine Division or the Health Examination Center of the general hospital in Seoul between 2010 and 2012. Measurements of biochemical and dietary variables repeated three times were collected from a total of 138 subjects at 3- to 4-month intervals when the subjects visited the hospital. Dietary intake data were obtained using 24-h recalls. In order to estimate typical values for biochemical and dietary variables, the averages of repeated measures for each subject were calculated. To identify dyslipidemia patterns, factor analysis was used based on total cholesterol (TC), low-density lipoprotein cholesterol (LDLC), triglycerides (TG), and high-density lipoprotein cholesterol (HDLC). Two dyslipidemia patterns, (1) TC & LDLC and (2) TG & HDLC, were identified. Dietary fat and cholesterol intakes were positively associated with the TC & LDLC pattern score, but not associated with the TG & HDLC pattern score. The TG & HDLC pattern was significantly associated with low intakes of calcium, potassium, milk and dairy products. Two dyslipidemia patterns were associated with dietary factors in Korean adults. Further studies should investigate specific dietary recommendations according to lipid profiles in the prevention and management of dyslipidemia in Korea.

We have learned that low-density lipoprotein (LDL) cholesterol is the cause of atherosclerosis from various aspects, including a single case with familial hypercholesterolemia, other cases with different types of Mendelian dyslipidemias, large-scale randomized controlled trials using LDL cholesterol lowering therapies, and Mendelian randomization studies using common as well as rare variants associated with LDL cholesterol levels. There is no doubt that determinations of genotypes in lipid-associated genes have contributed not only to the genetic diagnosis for Mendelian dyslipidemias but also to the discoveries of novel therapeutic targets. Furthermore, recent studies have shown that such genetic information could provide useful clues for the risk prediction as well as risk stratification in general and in particular population. We provide the current understanding of genetic analyses relating to plasma lipids and coronary artery disease. PMID:28250266

Atherogenic dyslipidemia is an important risk factor for cardiovascular disease. We aim to determine atherogenic dyslipidemia prevalence in primary care patients at moderate-very high cardiovascular risk and its associated cardiovascular risk perception in Spain. This cross-sectional study included 1137 primary care patients. Patients had previous cardiovascular disease, diabetes mellitus, SCORE risk ≥ 3, severe hypertension or dyslipidemia. Atherogenic dyslipidemia was defined as low HDL-C (<40 mg/dL [males], <50 mg/dL [females]) and elevated triglycerides (≥ 150 mg/dL). A visual analog scale was used to define a perceived cardiovascular disease risk score. Mean age was 63.9 ± 9.7 years (64.6% males). The mean BMI was 29.1 ± 4.3 kg/m(2), and mean waist circumference 104.2 ± 12.7 cm (males), and 97.2 ± 14.0 cm (females). 29.4% were smokers, 76.4% had hypertension, 48.0% were diabetics, 24.7% had previous myocardial infarction, and 17.8% peripheral arterial disease. European guidelines classified 83.6% at very high cardiovascular risk. Recommended HDL-C levels were achieved by 50.1% of patients and 37.3% had triglycerides in the reference range. Target LDL-C was achieved by 8.8%. The overall atherogenic dyslipidemia prevalence was 27.1% (34.1% in diabetics). This prevalence in patients achieving target LDL-C was 21.4%. Cardiovascular risk perceived by patients was 4.3/10, while primary care physicians scored 5.7/10. When LDL-C levels are controlled, atherogenic dyslipidemia is more prevalent in those patients at highest cardiovascular risk and with diabetes. This highlights the importance of intervention strategies to prevent the residual vascular risk in this population. Both patients and physicians underestimated cardiovascular risk.

To analyze associations of sedentary behavior and physical activity with dyslipidemia among residents in Wuhai city. Data about social demographic characteristics, life style, health status and other covariate required for analysis in this study was obtained from a cross-sectional study on a total of 11 497 18-79 years old residents in Wuhai City by questionnaire, body mea-surement and laboratory examination. In this study, sedentary behavior and physical activity were evaluated using international physical activity questionnaire long version (IPAQ). IPAQ is widely used all over the world, and its reliability and validity have been tested in Chinese population. 2016 Chinese Guideline for the Management of Dyslipidemia in Adults was used to define dyslipidemia in this study. According to IPAQ scoring protocol, 124 participants were excluded as a result of reporting more than 960 min of physical activity per day. 50.58% of 11 373 participants included in the analysis reported more than 4 hours of sedentary behavior per day in this study, thus 49.42% participants reported no more than 4 hours of sedentary behavior per day; the proportions of these 11 373 participants who reached Low level physical activity, Moderate level physical activity and high level physical activity were 23.43%, 37.29% and 39.28% respectively; and the detection ratios of new cases and prevalent cases of dyslipidemia in Wuhai City were 20.46% and 16.13% respectively. After controlling for confounders in this study, we found out that sedentary behavior increased the risk of new cases of dyslipidemia in women (OR=1.17, 95% CI: 1.00-1.36), and increased the risk of prevalent cases of dyslipidemia in both men (OR=1.21, 95% CI: 1.02-1.44) and women (OR=1.24, 95% CI: 1.04-1.48); as for association of physical activity with dyslipidemia, association was found between high level physical activity and prevalent cases of dyslipidemia in men in this study (OR=0.78, 95% CI: 0.62-0.98), suggested that high

The increasing prevalence of dyslipidemia has become a worldwide public health problem, and the prevalence varies widely according to socioeconomic, cultural and ethnic characteristics. Chongqing has experienced rapid economic development and is now the economic center of Southwestern China. There are scant data on serum lipid profile of residents in Chongqing, the largest municipality directly under the Central Government in China. We conducted a cross-sectional study in a representative sample of 5375 residents of Chongqing, aged ≥18 years, and estimated the prevalence of dyslipidemia and its associated risk factors. According to the National Cholesterol Education Program-Adult Treatment Panel III criteria, the age-standardized prevalence of dyslipidemia was 35.5% (34.4% among men and 37.6% among women). Among the 2009 patients with dyslipidemia, 44.2% had isolated hypertriglyceridemia, 14.7% had isolated hypercholesterolemia, 13.2% had mixed hyperlipidemia, and 28.0% had isolated low high-density lipoprotein cholesterol. The peak prevalence of dyslipidemia in men was between 30 and 39 years (48.2%), and then declined gradually; in women, the prevalence of dyslipidemia increased with age, with the peak prevalence occurring after age 60 (46.3%). Multivariable logistic regression analysis revealed that dyslipidemia was associated with age, education level, physical activity, obesity and central obesity for both men and women. In conclusion, the results indicated dyslipidemia, particularly hypertriglyceridemia and low high-density lipoprotein cholesterol, are very common in Chongqing. To prevent dyslipidemia, it is essential to conduct appropriate intervention programs aimed at risk factor reduction and implement routine screening programs for blood lipid levels in Chongqing, China.

Dyslipidemia may occur in younger adults (defined as persons aged 21 to 39 years) and is an important risk factor for cardiovascular disease. Screening might identify younger adults with asymptomatic dyslipidemia who may benefit from lipid-lowering therapies. To update the 2008 U.S. Preventive Services Task Force review on dyslipidemia screening in younger adults. The Cochrane Central Register of Controlled Trials, the Cochrane Database of Systematic Reviews, and MEDLINE through May 2016, and reference lists. Randomized, controlled trials; cohort studies; and case-control studies on screening for or treatment of asymptomatic dyslipidemia in adults aged 21 to 39 years. The plan was for 1 investigator to abstract data and a second to check their accuracy, and for 2 investigators to independently assess study quality; however, no studies met the inclusion criteria. No study evaluated the effects of lipid screening versus no screening, treatment versus no treatment, or delayed versus earlier treatment on clinical outcomes in younger adults. In addition, no study evaluated the diagnostic yield of alternative screening strategies (such as targeted screening of persons with a family history of hyperlipidemia vs. general screening) in younger adults. No direct relevant evidence. Direct evidence on the benefits and harms of screening for or treatment of dyslipidemia in younger adults remains unavailable. Estimating the potential effects of screening for dyslipidemia in this population requires extrapolation from studies performed in older adults. Agency for Healthcare Research and Quality.

Down Syndrome (DS) shows an increased risk of chronic diseases, associated to higher morbidity and mortality for cardiovascular disease. Some studies have shown a worse lipid profile in children with DS, however, until now there is no recommendation for screening for dyslipidemia in these subjects. To describe the frequency of dyslipidemia in a population of Chilean children and adolescents with DS. Retrospective study, including patients with DS, aged 2 to 18 years, who participated in a special health care program for people with DS in Health Net UC CHRISTUS, between 2007 and 2015. Patients who had a lipid profile between their routine laboratory tests were included. Clinical characteristics, relevant comorbidities, malformations, medications, nutritional status and pubertal development were obtained from medical records. Diagnosis of dyslipidemia was considered according to the criteria of the NHLBI 2011. The medical records of 218 children with DS were revised, 58,3% had some type of dyslipidemia. The most frequent single dyslipidemias were low HDL Chol (15,1%) and hypertriglyceridemia (12,8%). Atherogenic dyslipidemia (low HDL plus hypertriglyceridemia) was the most frequent combined dyslipidemia (13,3%). The occurrence of atherogenic dyslipidemia was not associated with overnutrition and obesity. A high frequency of dyslipidemia was found in Chilean children and adolescents with DS. Our results make us suggest that lipid profile should be performed early in all patients with DS, independent of the presence of risk factors for dyslipidemia.

Atherogenic dyslipidemia, which is characterized by increased triglyceride levels and reduced HDL cholesterol levels, is underestimated and undertreated in clinical practice. We assessed its prevalence and the achievement of therapeutic objectives for HDL cholesterol and triglyceride levels in patients treated at lipid and vascular risk units in Spain. This was an observational, longitudinal, retrospective, multicenter study performed in 14 autonomous Spanish communities that consecutively included 1828 patients aged ≥18 years who were referred for dyslipidemia and vascular risk to 43 lipid clinics accredited by the Spanish Society of Arteriosclerosis. We collected information from the medical records corresponding to 2 visits conducted during 2010 and 2011-12, respectively. Of the 1649 patients who had a lipid profile in the first visit (90.2%), 295 (17.9%) had atherogenic dyslipidemia. The factors associated with atherogenic dyslipidemia were excess weight/obesity, not taking hypolipidemic drugs (statins and/or fibrates), diabetes, myocardial infarction and previous heart failure. Of the 273 (92.5%) patients with atherogenic dyslipidemia that had a lipid profile in the last visit, 44 (16.1%) achieved the therapeutic objectives for HDL cholesterol and triglyceride levels. The predictors of therapeutic success were normal weight and normoglycemia. One of every 6 patients treated in lipid and vascular risk units had atherogenic dyslipidemia. The degree to which the therapeutic goals for HDL cholesterol and triglyceride levels were achieved in these patients was very low. Copyright © 2014 Elsevier España, S.L.U. All rights reserved.

Dyslipidemia: Obese or Not Obese-That Is Not the Question.

Purpose of review: It is becoming increasingly clear that some obese individuals do not develop dyslipidemia and instead remain healthy, while some normal weight individuals become dyslipidemic and unhealthy. The present review examines the similarities and differences between healthy and unhealthy individuals with and without obesity and discusses putative underlying mechanisms of dyslipidemia. The presence of dyslipidemia and compromised metabolic health in both lean and obese individuals suggests that the obese phenotype per se does not represent a main independent risk factor for the development of dyslipidemia and that dyslipidemia, rather than obesity, may be the driver of metabolic diseases. Notably, adipose tissue dysfunction and ectopic lipid deposition, in particular in the liver, seems a common trait of unhealthy individuals.

Timely detection and characterization of this condition help clinicians estimate future risk of cardiovascular disease and take appropriate preventive measures. The aim of this study was to determine the prevalence, pattern and predictors of dyslipidemia in a cohort of Nepalese patients with type 2 diabetes. We found mixed dyslipidemia as the most prevalent (88.1%) and isolated dyslipidemia (10.1%) as the least prevalent forms of dyslipidemia in our patients. The most prevalent form of single dyslipidemia was high LDL-C (73.8%) and combined dyslipidemia was high TG, high LDL-C and low HDL-C (44.7%). Prevalence of all single and mixed dyslipidemia was higher in patients with poor glycemic control and hypertension. The glycemic status of patients correlated with their fasting serum lipid profile. Dyslipidemia was associated mainly with male gender, poor glycemic control and hypertension. Atherogenic dyslipidemia is associated mainly with male gender, poor glycemic control and hypertension. It is highly prevalent in Nepalese patients with type 2 diabetes. Urgent lifestyle modification, sustained glycemic control and aggressive lipid lowering treatment plans are necessary to minimize the future risk of cardiovascular disease in this population.

Cadmium is a widespread environmental and occupational pollutant that accumulates in human body with a biological half-life exceeding 10 years. Cadmium exposure has been demonstrated to increase rates of cardiovascular diseases. Whether occupational cadmium exposure is associated with the increase in the prevalence of dyslipidemia and hence contributes to the risk of cardiovascular diseases is still equivocal. To test the hypothesis that exposure to cadmium is related to the prevalence of dyslipidemia, we examined the associations between blood cadmium concentration and the prevalence of dyslipidemia in workers occupationally exposed to cadmium in China. A cross-sectional survey on demographic data, blood cadmium level and lipid profile in cadmium exposed workers from seven cadmium smelting factories in central and southwestern China was conducted. We measured blood cadmium concentration and lipid components of 1489 cadmium exposed workers. The prevalence of dyslipidemia was compared across blood cadmium quartiles. Associations between the blood cadmium concentrations and the prevalence of dyslipidemia were assessed using confounder adjusted linear and logistic regressions. The blood cadmium concentration was 3.61±0.84µg/L ( mean ±SD). The prevalence of dyslipidemia in this occupational population was 66.3%. Mean blood cadmium concentration of workers with dyslipedemia was significantly higher than that of workers without dyslipidemia (p <0.01). The prevalence of dyslipidemia increased dose-dependently with elevations in blood cadmium concentrations (p for trend <0.001). Elevated levels of blood cadmium were associated with BMI, education attainment, income, smoking status and duration of exposure (all p <0.01). Furthermore, the profile of blood lipid was obviously changed in this occupational population. The prevalence of high TC, high TG, Low HDL-C and high LDL-C rose with increases in blood cadmium levels dose-dependently (p for trend <0.001). The odds ratios

The renin-angiotensin system (RAS) is an important therapeutic target in the treatment of hypertension. Obesity has emerged as a primary contributor to essential hypertension in the United States and clusters with other metabolic disorders (hyperglycemia, hypertension, high triglycerides, low HDL cholesterol) defined within the metabolic syndrome. In addition to hypertension, RAS blockade may also serve as an effective treatment strategy to control impaired glucose and insulin tolerance and dyslipidemias in patients with the metabolic syndrome. Hyperglycemia, insulin resistance, and/or specific cholesterol metabolites have been demonstrated to activate components required for the synthesis [angiotensinogen, renin, angiotensin-converting enzyme (ACE)], degradation (ACE2), or responsiveness (angiotensin II type 1 receptors, Mas receptors) to angiotensin peptides in cell types (e.g., pancreatic islet cells, adipocytes, macrophages) that mediate specific disorders of the metabolic syndrome. An activated local RAS in these cell types may contribute to dysregulated function by promoting oxidative stress, apoptosis, and inflammation. This review will discuss data demonstrating the regulation of components of the RAS by cholesterol and its metabolites, glucose, and/or insulin in cell types implicated in disorders of the metabolic syndrome. In addition, we discuss data supporting a role for an activated local RAS in dyslipidemias and glucose intolerance/insulin resistance and the development of hypertension in the metabolic syndrome. Identification of an activated RAS as a common thread contributing to several disorders of the metabolic syndrome makes the use of angiotensin receptor blockers and ACE inhibitors an intriguing and novel option for multisymptom treatment.

Rašlová, Katarína

Diabetes mellitus is a group of metabolic diseases that are characterized by hyperglycemia resulting from defects in insulin secretion, insulin action, or both. The cause of premature death among patients with diabetes predominantly involves cardiovascular diseases. The risk of death from cardiovascular complications is so high that diabetes mellitus is considered a risk equivalent to a manifest atherosclerotic disease. High cardiovascular risk is also determined by dyslipidemia which is present in a large number of patients with diabetes. The review is devoted to the pathogenesis of dyslipidemia in type 1 and type 2 diabetes with an emphasis on atherogenic dyslipidemia. It describes the strategy of therapeutic procedures and their effect on cardiovascular morbidity and mortality.Key words: atherogenic dyslipidemia - fibrates - statins - type 2 diabetes mellitus.

Patients infected with HIV are at high risk for dyslipidemia, insulin resistance and cardiovascular disease. Therapies to reverse these risks are complex, sometimes controversial, and not uniformly effective. Pathophysiology of the lipid abnormalities in HIV is discussed, including the causes of alterations in triglycerides, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol and insulin resistance. We discuss the therapy of dyslipidemia in HIV using a combination of available clinical evidence and expert opinion based on extensive clinical experience, with discussions of lifestyle intervention and diet, conventional pharmacotherapy with lipid-lowering medications including statins, fibrates, niacin and thiazolidinediones for dyslipidemia, and newer therapeutic approaches including omega fatty acids, acipimox, growth hormone and leptin. A detailed understanding of the pathophysiology and rational or evidence-based approach to therapy of lipid abnormalities in patients infected with HIV. Treatment of dyslipidemia in patients with HIV is challenging and complicated by the risk of drug interactions. Appropriate therapy requires a sound understanding of pathophysiology and the principles of pharmacological and nonpharmacological therapeutic interventions. An evidence-based approach that combines lifestyle changes and drugs that are both safe and effective, singly and in combination, is described.

Toenail mercury and dyslipidemia: Interaction with selenium.

2017-01-01

Although compelling evidences from in vivo and in vitro studies exist, limited studies have examined the association between chronic mercury exposure and dyslipidemia. Particularly, data are sparse regarding the influence of selenium on this association of mercury with dyslipidemia in humans. The purpose of the current study was to examine the associations of toenail mercury with dyslipidemia and its components, and to examine whether selenium in toenails modifies these associations. We performed cross-sectional analyses using baseline data from a cohort in the Yeungnam area in South Korea, including 232 men and 269 women. Toenail mercury and selenium concentrations were quantified using neutron activation analysis, and fasting serum lipid measurements were obtained through the medical examination. Odds ratios of the prevalent hypercholesterolemia, hyper-LDL-cholesterolemia, hypo-HDL-cholesterolemia, hypertriglyceridemia, and dyslipidemia in correlation with mercury levels were calculated using multivariable logistic regression. The mean levels of toenail mercury were 0.47μg/g for men and 0.34μg/g for women. After adjustment for multiple confounding variables, participants in the highest tertile of toenail mercury levels had 4.08 (95% CI 1.09-15.32, p for trend=0.02) times higher risk of hyper-LDL-cholesterolemia, and 2.24 (95% CI 1.15-4.37, p for trend=0.004) times higher risk of dyslipidemia than those in the lowest tertile. Selenium is a significant effect-modifier for these associations; the highest tertile of toenail mercury were significantly associated with a higher risk of hypercholesterolemia (OR 5.25, 95% CI 1.04-26.38) and dyslipidemia (OR 2.98, 95% CI 1.16-7.66) compared to the lowest tertile at toenail selenium levels ≤0.685μg/g, while these associations became weak and non-significant, showing OR 0.98 and 95% CI 0.25-3.80 for hypercholesterolemia and OR 1.99 and 95% CI 0.73-5.45 for dyslipidemia at toenail selenium levels >0.685μg/g.

To evaluate current approaches and explore emerging research related to dyslipidemia management. MEDLINE (2004-April 2012) was searched for randomized controlled trials using the terms dyslipidemia and lipid-lowering therapy or statin (>1000 hits). Separate searches (MEDLINE, Google) identified meta-analyses (2010-2011), disease prevalence statistics, and current consensus guidelines (2004-July 2011). Additional references were identified from the publications reviewed. English-language articles on large multicenter trials were evaluated. National Cholesterol Education Program Adult Treatment Panel III guidelines for the reduction of cardiovascular risk recommend the attainment of specific low-density lipoprotein cholesterol (LDL-C) and non-high-density lipoprotein cholesterol (non-HDL-C) target values, based on an individual's 10-year risk of coronary heart disease or global risk. For most patients unable to achieve recommended lipid level goals with therapeutic lifestyle changes, statins are the first option for treatment. Results of large, well-controlled clinical trials have demonstrated that statins are effective in primary and secondary prevention of cardiovascular disease in diverse populations, including patients with diabetes and the elderly, and that intensive statin therapy provides more effective lipid goal attainment and significantly greater risk reduction in patients with coronary artery disease. Statin therapy is generally well tolerated but may increase the risk of myopathy. Statin use has been associated with increases in hepatic transaminases and an increased risk of diabetes, although the absolute risk of diabetes is low compared with the risk reduction benefit. Combination therapy including a statin may be appropriate for certain populations, but the risk reduction benefits of combination therapy remain unclear. Ezetimibe is an important treatment option for patients with hypercholesterolemia who do not tolerate intensive statin therapy

The new dyslipidemia guidelines: what is the debate?

Dyslipidemia is a major risk factor for the development of atherosclerotic disease. Therefore, lifestyle interventions and pharmacological approaches to decrease cholesterol are widely used in cardiovascular disease prevention. The introduction and widespread use of 3-hydroxy-3 methylglutaryl coenzyme A inhibitors (statins) for individuals at risk of atherosclerotic disease has been an important advance in cardiovascular care. There can be no doubt that better control of dyslipidemia, even in subjects whose low-density lipoprotein cholesterol level is not particularly high, has reduced overall event rates. On a background of lifestyle interventions, statins are routinely used to decrease risk along with aspirin and interventions to control hypertension and diabetes. More than other risk factors, the approach to the identification and treatment of dyslipidemia has been heterogeneous and widely debated. The recent release of the 2013 American College of Cardiology/American Heart Association dyslipidemia guidelines has reignited the controversy over the best approach for risk stratification and treatment. In this article we review the importance of statin therapy for global cardiovascular risk reduction, compare the Canadian Cardiovascular Society dyslipidemia guidelines with other standards, and discuss the points of debate. Despite the seeming variety of recommendations, their common link is a systematic approach to risk stratification and treatment, which will continue to benefit our patients at risk.

Obesity and Dyslipidemia in South Asians

PubMed Central

Misra, Anoop; Shrivastava, Usha

2013-01-01

Obesity and dyslipidemia are emerging as major public health challenges in South Asian countries. The prevalence of obesity is more in urban areas than rural, and women are more affected than men. Further, obesity in childhood and adolescents is rising rapidly. Obesity in South Asians has characteristic features: high prevalence of abdominal obesity, with more intra-abdominal and truncal subcutaneous adiposity than white Caucasians. In addition, there is greater accumulation of fat at “ectopic” sites, namely the liver and skeletal muscles. All these features lead to higher magnitude of insulin resistance, and its concomitant metabolic disorders (the metabolic syndrome) including atherogenic dyslipidemia. Because of the occurrence of type 2 diabetes, dyslipidemia and other cardiovascular morbidities at a lower range of body mass index (BMI) and waist circumference (WC), it is proposed that cut-offs for both measures of obesity should be lower (BMI 23–24.9 kg/m2 for overweight and ≥25 kg/m2 for obesity, WC ≥80 cm for women and ≥90 cm for men for abdominal obesity) for South Asians, and a consensus guideline for these revised measures has been developed for Asian Indians. Increasing obesity and dyslipidemia in South Asians is primarily driven by nutrition, lifestyle and demographic transitions, increasingly faulty diets and physical inactivity, in the background of genetic predisposition. Dietary guidelines for prevention of obesity and diabetes, and physical activity guidelines for Asian Indians are now available. Intervention programs with emphasis on improving knowledge, attitude and practices regarding healthy nutrition, physical activity and stress management need to be implemented. Evidence for successful intervention program for prevention of childhood obesity and for prevention of diabetes is available for Asian Indians, and could be applied to all South Asian countries with similar cultural and lifestyle profiles. Finally, more research on

Large epidemiologic studies support the role of dyslipidemia in preeclampsia; however, the etiology of preeclampsia or whether dyslipidemia plays a causal role remains unclear. We examined the association between the genetic predisposition to dyslipidemia and risk of preeclampsia using validated genetic markers of dyslipidemia. Preeclampsia cases (n = 164) and normotensive controls (n = 110) were selected from live birth certificates to nulliparous Iowa women during the period August 2002 to May 2005. Disease status was verified by medical chart review. Genetic predisposition to dyslipidemia was estimated by 4 genetic risk scores (GRS) (total cholesterol (TC), LDL cholesterol (LDL-C), HDL cholesterol (HDL-C), and triglycerides) on the basis of established loci for blood lipids. Logistic regression analyses were used to evaluate the relationships between each of the 4 genotype scores and preeclampsia. Replication analyses were performed in an independent, US population of preeclampsia cases (n = 516) and controls (n = 1,097) of European ancestry. The GRS related to higher levels of TC, LDL-C, and triglycerides demonstrated no association with the risk of preeclampsia in either the Iowa or replication population. The GRS related to lower HDL-C was marginally associated with an increased risk for preeclampsia (odds ratio (OR) = 1.03, 95% confidence interval (CI) = 0.99-1.07; P = 0.10). In the independent replication population, the association with the HDL-C GRS was also marginally significant (OR = 1.03, 95% CI: 1.00-1.06; P = 0.04). Our data suggest a potential effect between the genetic predisposition to dyslipidemic levels of HDL-C and an increased risk of preeclampsia, and, as such, suggest that dyslipidemia may be a component along the causal pathway to preeclampsia. © American Journal of Hypertension, Ltd 2014.

To assess the attitude of primary care (PCPs) and specialized care (SCPs) physicians towards the general set of patients with dyslipidemia, particularly those with cardiovascular risk factors. Observational, descriptive, multi-center study based on a survey. Different healthcare regions in Spain. 1,402 PCPs, and 596 SCPs. Physician's profile, routine practices in the management of patients with dyslipidemia. 84.3% took the global cardiovascular risk into account when prescribing the treatment. Target LDL-C concentration in patients without cardiovascular risk factors was <130mg/dL and <160mg/dL for 51.9% and 29.0% of physicians, respectively. In smokers and patients with hypertension or diabetes, the LDL target was <100mg/dL for 49-55% of physicians, whereas in patients with cardiovascular complication, ischemic cardiopathy or stroke, target LDL-C was <70mg/dL in 71-88% of them. First-line treatment for patients without cardiovascular risk factors was atorvastatin (66%), whereas in patients with diabetes, kidney disease or metabolic syndrome, most physicians (80-89%) used pitavastatin. SCPs showed a greater trend than PCPs to establish a LDL-C target of <70mg/dL in patients with previous stroke (77.5% vs 66.8%) or coronary disease (92.1% vs 80.6%) (P<.0001), as well as to prescribe a combined treatment in patients not achieving the target LDL-C concentrations (58.1% vs 50.2%, P=.0013). Although CVR assessment is generally accepted, there is broad disagreement in defining the objectives of LDL-C. Most often than PCPs, the SCPs consider more ambitious targets for LDL-C and the association of lipid-lowering drugs. Copyright © 2017 Elsevier España, S.L.U. All rights reserved.

Objective Higher selenium level has been hypothesized to have the potential to reduce the risk of cardiovascular diseases including dyslipidemia. However, results from previous studies are inconsistent. This study aims to determine the association between selenium level and dyslipidemia in elderly Chinese with relatively low selenium status. Methods A cross-sectional study of 1859 participants aged 65 or older from four rural counties in China was conducted. Serum total cholesterol (TC), triglycerides (TG), high density lipoprotein-cholesterol (HDLC) and low-density lipoprotein-cholesterol (LDLC), nail selenium concentration and APOE genotype were measured in all subjects. The four types of dyslipidemia were defined as >5.17mmol/L for High-TC, >1.69 mmol/L for High-TG, >3.36 mmol/L for High-LDLC, and <1.04 mmol/L for Low-HDLC according to Chinese Guidelines on Prevention and Treatment of Dyslipidemia in Adults. Logistic models adjusting for age, gender, APOE genotype, body mass index, alcohol consumption, smoking, physical activity, medication use for cardiovascular diseases were used to examine the relationship between selenium levels and the risk of dyslipidemia. Results Mean nail selenium concentration was 0.465μg/gin this sample. Rates for High-TC, High-LDLC, High-TG, Low-HDLC were 18.13%, 13.23%, 12.21% and 32.76% respectively. Results from logistic models indicated that higher selenium levels were significantly associated with higher risk of High-TC, High-LDLC and lower risk of Low-HDLC adjusting for covariates (p < 0.0001). Compared with the lowest selenium quartile group, participants in selenium quartile groups 2, 3 and 4 had significantly higher rates of High-TC, High-LDLC, High-TG, and lower rate of Low-HDLC adjusting for covariates. No significant association was observed between selenium level and the risk of High-TG. APOEε4 carriers had higher rates of High-TC and High-LDLC. There was no interaction between selenium level and APOE with the rates of

Dyslipidemias are a key cardiovascular risk factor, and are increased since early childhood. The objective of this study was to describe the prevalence, characteristics of dyslipidemias and associated factors in a population of Chilean children. Cross-sectional study done in school-age children from Santiago, Chile (2009-2011). Parents answered questions about family medical history and children answered questions about physical activity. Anthropometry was performed and in a blood sample (12 hours fast) lipid profile, glycemia and insulinemia were measured. We recruited 2900 euglycemic children, 11.4 ± 0.97 years old, 52% girls. According to BMI, 22.5% were overweight and 15,3% had obesity. Considering recommended cut-off points for lipids, 69.3% were in acceptable range, 19.2% at risk and 11.5% at high cardiovascular risk. In total, 32% of the population had any clinical form of dyslipidemia: Isolated hypertriglyceridemia (9.4%), low HDL-C (7.6%), isolated hypercholesterolemia (4.9%), atherogenic dyslipidemia (6.24%) and mixed dyslipidemia (3.9%). Except for isolated hypercholesterolemia, dyslipidemias were more frequent in girls (globally 36.2% vs. 27.4%, p<0.0001). Low HDL-C was associated with sedentary lifestyle. In multiple logistic regression analysis, nutritional status was the most important associated factor, with less influence of age, sex, central obesity, insulin resistance and history of parental cardiovascular risk factors. In this population of Chilean school-age children, we found a high prevalence of dyslipidemia, and the principal determinant was weight excess. Copyright AULA MEDICA EDICIONES 2014.

Childhood-onset obesity is associated with increased mortality and morbidity related to cardiovascular diseases (CVD) during adulthood. Dyslipidemia has a fundamental role in the pathogenesis of CVD. This study aimed to evaluate the prevalence of dyslipidemia and related factors among obese children and adolescents. Obese patients aged between 2 and 18 years were included in the study. Serum concentrations of total cholesterol (TC), triglyceride (TG), low-density lipoprotein (LDL-C), high-density lipoprotein (HDL-C), fasting glucose levels, insulin, thyroid-stimulating hormone (TSH), free thyroxine (fT4), alanine aminotransferase (ALT), aspartate aminotransferase (AST), and liver ultrasound findings were evaluated retrospectively. Among 823 obese patients, 353 (42.9%) met the dyslipidemia criteria: 21.7% had hypertriglyceridemia, 19.7% had low levels of HDL-C, 18.6% had hypercholesterolemia, and 13.7% had high levels of LDL-C. Older age and/or high body mass index (BMI) were related to increased prevalence of dyslipidemia. Hepatosteatosis was more common among dyslipidemic patients. The frequency of insulin resistance (IR) and of higher levels of ALT and TSH were also detected in dyslipidemic patients. Patients with both dyslipidemia and grade 2-3 hepatosteatosis had higher levels of ALT, AST and TSH and lower levels of fT4. Prevalence of dyslipidemia is high in obese children, and hypertriglyceridemia is in the foreground. Higher levels of IR and more apparent abnormal liver function test results are observed in the context of dyslipidemia and hepatosteatosis coexistence. Metabolic and hormonal alterations related with thyroid functions may also be associated with dyslipidemia and hepatosteatosis in obese patients.

Dyslipidemia has significantly contributed to the increase of death and morbidity rates related to cardiovascular diseases. Clinical nutrition service provided by dietitians has been reported to have a positive effect on relief of medical symptoms or reducing the further medical costs. However, there is a lack of researches to identify key competencies and job standard for clinical dietitians to care patients with dyslipidemia. Therefore, the purpose of this study was to analyze the job components of clinical dietitian and develop the standard for professional practice to provide effective nutrition management for dyslipidemia patients. The current status of clinical nutrition therapy for dyslipidemia patients in hospitals with 300 or more beds was studied. After duty tasks and task elements of nutrition care process for dyslipidemia clinical dietitians were developed by developing a curriculum (DACUM) analysis method. The developed job standards were pretested in order to evaluate job performance, difficulty, and job standards. As a result, the job standard included four jobs, 18 tasks, and 53 task elements, and specific job description includes 73 basic services and 26 recommended services. When clinical dietitians managing dyslipidemia patients performed their practice according to this job standard for 30 patients the job performance rate was 68.3%. Therefore, the job standards of clinical dietitians for clinical nutrition service for dyslipidemia patients proposed in this study can be effectively used by hospitals.

The aim of the study was to determine the prevalence of dyslipidemia among primary care patients with hypertension and diabetes in Jamaica and the proportion of patients who achieve recommended targets. An audit of 500 dockets of adult patients with chronic disease attending public primary care clinics in Jamaica was conducted between October and December 2013. Data were collected on patient characteristics including medical history, medications, anthropometry, and lipid profiles (since January 1, 2011). Lipid targets were based on the Ministry of Health 2007 management guidelines. Stepwise multivariable logistic regression analysis was performed to determine the predictors of achieving lipid targets. Four hundred and thirty-seven patient records had a lipid profile done and 90% of these had at least one abnormal lipid value. 15.3% of the patients achieved the low density lipoprotein cholesterol (LDL-C) target, 63.2% high density lipoprotein cholesterol (HDL-C), 85.1% triglycerides and 57.4% the total cholesterol target. Statins were prescribed for 49% and these patients were less likely to achieve LDL-C (OR = 0.57; 95% CI: 0.33-0.97; p = 0.04) or total cholesterol (OR = 0.21; 95% CI: 0.13-0.33; p < 0.001) targets. Patients over 80 years were more likely to achieve the LDL-C target (OR = 3.21; 95% CI: 1.64-6.28; p = 0.002) than those less than 50 years old. More men than women achieved total cholesterol targets (OR = 2.2; 95% CI: 1.4-3.6; p = 0.001). Dyslipidemia is widespread among primary care patients with hypertension and diabetes. The proportion of patients who achieve the respective lipid targets must be documented and routinely monitored and appropriate medication and lifestyle changes implemented to improve this.

Dyslipidemia and its therapeutic challenges in renal transplantation.

Cardiovascular disease is the leading cause of mortality in kidney transplant recipients. Dyslipidemia is a common finding after renal transplantation and a significant risk factor in the development of coronary heart disease. Although a causal relationship with cardiovascular mortality has not been proven in the transplant population, it is reasonable to extrapolate data from the general population and aggressively treat posttransplant dyslipidemia. Statins are considered the agents of choice, though their use may be complicated by drug misadventures. Pravastatin, fluvastatin and pitavastatin are considered to be the safest statins to use in this population; however, given their low-potency, a high-potency statin, such as atorvastatin, may be necessary in patients with significant dyslipidemia. In this article, we discuss the etiology of and treatment strategies for dyslipidemia in renal transplant recipients based on a literature review of potential therapeutic adverse effects and benefits in this population. We will also evaluate the reasons for and consequences of the latest Food and Drug Administration (FDA) warnings regarding the use of simvastatin. © Copyright 2012 The American Society of Transplantation and the American Society of Transplant Surgeons.

Although atherogenic dyslipidemia is a recognized cardiovascular risk factor, it is often underassessed and thus undertreated and poorly controlled in clinical practice. The objective of this study was to reach a multidisciplinary consensus for the establishment of a set of clinical recommendations on atherogenic dyslipidemia to optimize its prevention, early detection, diagnostic evaluation, therapeutic approach, and follow-up. After a review of the scientific evidence, a scientific committee formulated 87 recommendations related to atherogenic dyslipidemia, which were grouped into 5 subject areas: general concepts (10 items), impact and epidemiology (4 items), cardiovascular risk (32 items), detection and diagnosis (19 items), and treatment (22 items). A 2-round modified Delphi method was conducted to compare the opinions of a panel of 65 specialists in cardiology (23%), endocrinology (24.6%), family medicine (27.7%), and internal medicine (24.6%) on these issues. After the first round, the panel reached consensus on 65 of the 87 items discussed, and agreed on 76 items by the end of the second round. Insufficient consensus was reached on 3 items related to the detection and diagnosis of atherogenic dyslipidemia and 3 items related to the therapeutic goals to be achieved in these patients. The external assessment conducted by experts on atherogenic dyslipidemia showed a high level of professional agreement with the proposed clinical recommendations. These recommendations represent a useful tool for improving the clinical management of patients with atherogenic dyslipidemia. A detailed analysis of the current scientific evidence is required for those statements that eluded consensus. Copyright © 2013 Sociedad Española de Cardiología. Published by Elsevier Espana.

The distinction between a monogenic dyslipidemia and a polygenic/environmental dyslipidemia is important for the cardiovascular risk assessment, counseling, and treatment of these patients. The present work aims to perform the cardiovascular risk assessment of dyslipidemic children to identify useful biomarkers for clinical criteria improvement in clinical settings. Main cardiovascular risk factors were analyzed in a cohort of 237 unrelated children with clinical diagnosis of familial hypercholesterolemia (FH). About 40% carried at least two cardiovascular risk factors and 37.6% had FH, presenting mutations in LDLR and APOB. FH children showed significant elevated atherogenic markers and lower concentration of antiatherogenic particles. Children without a molecular diagnosis of FH had higher levels of TGs, apoC2, apoC3, and higher frequency of BMI and overweight/obesity, suggesting that environmental factors can be the underlying cause of their hypercholesterolem≥ia. An apoB/apoA1 ratio ≥0.68 was identified as the best biomarker (area under the curve = 0.835) to differentiate FH from other dyslipidemias. The inclusion in clinical criteria of a higher cut-off point for LDL cholesterol or an apoB/apoA1 ratio ≥0.68 optimized the criteria sensitivity and specificity. The correct identification, at an early age, of all children at-risk is of great importance so that specific interventions can be implemented. apoB/apoA1 can improve the identification of FH patients.

Dyslipidemia is a commonly encountered clinical condition and is an important determinant of cardiovascular disease. Although secondary factors play a role in clinical expression, dyslipidemias have a strong genetic component. Familial hypercholesterolemia is usually due to loss-of-function mutations in LDLR, the gene coding for low density lipoprotein receptor and genes encoding for proteins that interact with the receptor: APOB, PCSK9 and LDLRAP1. Monogenic hypertriglyceridemia is the result of mutations in genes that regulate the metabolism of triglyceride rich lipoproteins (eg LPL, APOC2, APOA5, LMF1, GPIHBP1). Conversely familial hypobetalipoproteinemia is caused by inactivation of the PCSK9 gene which increases the number of LDL receptors and decreases plasma cholesterol. Mutations in the genes APOB, and ANGPTL3 and ANGPTL4 (that encode angiopoietin-like proteins which inhibit lipoprotein lipase activity) can further cause low levels of apoB containing lipoproteins. Abetalipoproteinemia and chylomicron retention disease are due to mutations in the microsomal transfer protein and Sar1b-GTPase genes, which affect the secretion of apoB containing lipoproteins. Dysbetalipoproteinemia stems from dysfunctional apoE and is characterized by the accumulation of remnants of chylomicrons and very low density lipoproteins. ApoE deficiency can cause a similar phenotype or rarely mutations in apoE can be associated with lipoprotein glomerulopathy. Low HDL can result from mutations in a number of genes regulating HDL production or catabolism; apoAI, lecithin: cholesterol acyltransferase and the ATP-binding cassette transporter ABCA1. Patients with cholesteryl ester transfer protein deficiency have markedly increased HDL cholesterol. Both common and rare genetic variants contribute to susceptibility to dyslipidemias. In contrast to rare familial syndromes, in most patients, dyslipidemias have a complex genetic etiology consisting of multiple genetic variants as established

Frequency of Testing for Dyslipidemia: An Evidence-Based Analysis

PubMed Central

2014-01-01

Background Dyslipidemias include high levels of total cholesterol, low-density lipoprotein (LDL) cholesterol, and triglycerides and low levels of high-density lipoprotein (HDL) cholesterol. Dyslipidemia is a risk factor for cardiovascular disease, which is a major contributor to mortality in Canada. Approximately 23% of the 2009/11 Canadian Health Measures Survey (CHMS) participants had a high level of LDL cholesterol, with prevalence increasing with age, and approximately 15% had a total cholesterol to HDL ratio above the threshold. Objectives To evaluate the frequency of lipid testing in adults not diagnosed with dyslipidemia and in adults on treatment for dyslipidemia. Research Methods A systematic review of the literature set out to identify randomized controlled trials (RCTs), systematic reviews, health technology assessments (HTAs), and observational studies published between January 1, 2000, and November 29, 2012, that evaluated the frequency of testing for dyslipidemia in the 2 populations. Results Two observational studies assessed the frequency of lipid testing, 1 in individuals not on lipid-lowering medications and 1 in treated individuals. Both studies were based on previously collected data intended for a different objective and, therefore, no conclusions could be reached about the frequency of testing at intervals other than the ones used in the original studies. Given this limitation and generalizability issues, the quality of evidence was considered very low. No evidence for the frequency of lipid testing was identified in the 2 HTAs included. Canadian and international guidelines recommend testing for dyslipidemia in individuals at an increased risk for cardiovascular disease. The frequency of testing recommended is based on expert consensus. Conclusions Conclusions on the frequency of lipid testing could not be made based on the 2 observational studies. Current guidelines recommend lipid testing in adults with increased cardiovascular risk, with

The cardiovascular risk factors are clearly increasing in developing countries. Among these factors, dyslipidemia is often found, this due to the change in behavioral and dietary habits (OMS, 2006). Dyslipidemia is a "primary or secondary pathological changes in serum lipids". It is a chronic and metabolic abnormality, characterized by persistently elevated TG, LDL-c, and a decrease in HDL (Attias et al., 2013-2014). The objective of this study is to determine the prevalence of dyslipidemia, and give the lipid profile of the population in Gueoul. We performed a comprehensive observational study, cross-sectional descriptive on Senegalese aged 35 or over, living in Gueoul for at least 6 months. Lipid profile (total cholesterol, triglycerides, HDL-cholesterol, LDL-cholesterol) was systematically after 12hours of fasting. Dyslipidemia was found in 61.3 % of cases with 50 % pure hypercholesterolemia (n=705). Only 20 subjects (2.3 %) knew they had dyslipidemia. The detection rate was 59.8 % (n=844). The type most represented was hypoHDLemia (45.6 %) followed by hyperLDLemia (28.8 %). Triglycerides were increased in only 2.8 % of cases. The prevalence of dyslipidemia is very high in our regions. It is often associated with female gender, hypertension, diabetes, and obesity. Its main causes are physical inactivity, change in lifestyle and eating habits. It is often misunderstood and its management is limited in most cases to low-calorie diet. Copyright © 2015 Elsevier Masson SAS. All rights reserved.

Background Ferritin is associated with various cardiometabolic risk factors such as dyslipidemia, hypertension, obesity, and insulin resistance in adults. We aimed to study the association between serum ferritin levels and dyslipidemia in adolescents, because dyslipidemia is considered an important modifiable cardiovascular risk factor in the young. Methods We analyzed 1,879 subjects (1,026 boys and 853 girls) from the 2009–2010 Korean National Health and Nutrition Examination Survey IV. Subjects were categorized into quartiles according to their lipid parameters, which were classified according to age and gender. Those in the highest quartile groups for total cholesterol, low-density lipoprotein cholesterol (LDL-C), and triglyceride concentrations were diagnosed as having dyslipidemia. Those in the lowest quartile for high-density lipoprotein cholesterol (HDL-C) values were diagnosed with abnormal levels. Results In boys, total cholesterol, LDL-C, and triglyceride concentrations were significantly correlated with serum ferritin levels. In both boys and girls, serum ferritin levels were negatively associated with HDL-C values, even after adjusting for all covariates. Furthermore, there was no significant correlation between serum ferritin levels and total cholesterol, LDL, and triglyceride concentrations in girls. Conclusion Serum ferritin levels were significantly associated with major dyslipidemia parameters, more prominently in boys than in girls, and this association represents a cardiometabolic risk factor.

To analyze the prevalence, awareness, treatment, control and epidemiological characteristics of dyslipidemia in Chinese adults. In this cross-sectional study, we adopted a multi-stage, stratified sampling method to obtain representative samples of the general population aged >18 years from different urban and rural regions in China. All subjects completed a lifestyle and medical history questionnaire and were examined for risk factors. Dyslipidemia was defined according to criteria of the 2007 Chinese Guidelines on Prevention and Treatment of Dyslipidemia in Adults. Continuous variables were compared using variance analysis. Multivariate logistic regression analysis was performed to explore the risk factors of dyslipidemia. The prevalence of dyslipidemia was 34.0% overall, and 35.1%, and 26.3% in urban and rural areas, respectively. The prevalence of dyslipidemia was significantly higher in men than women (41.9% vs 32.5%; P < 0.001). Rates of awareness, treatment, and control were 31.0%, 19.5%, and 8.9%, respectively. Increasing age (OR = 1.012; 95% CI:1.010, 1.014), male sex (OR = 1.411; 95% CI:1.318, 1.510), obesity (OR = 1.424; 95% CI:1.345, 1.507), cardiovascular disease (OR = 1.343; 95% CI:1.125, 1.603), diabetes (OR = 1.955; 95% CI:1.751, 2.182), hypertension (OR = 1.481; 95% CI:1.391, 1.577) and hyperuricemia (OR = 2.223; 95% CI:2.060, 2.399) were independent risk factors of dyslipidemia. The prevalence of dyslipidemia among Chinese adults was high but awareness, treatment, and control of dyslipidemia were low. Urban high income earners and rural medium income earners show higher prevalence. Low income earners in urban and rural population have the worst awareness treatment, and control rate. There is an increased need for closely monitoring and controlling high risk factors in the populations including postmenopausal women, unhealthy lifestyle peoples and patients with chronic non-communicable diseases.

The prevalence of cardiovascular disease has been increasing worldwide. As a common pathogenic risk factor, dyslipidemia played a great role in the incidence and progress of these diseases. We investigated to achieve accurate and up-to-date information on the prevalence of dyslipidemia and its associations with other lipid-related diseases in rural North China. Using a complex, multistage, probability sampling design, we conducted a large-scale cross-sectional study of 8528 rural participants aged over 18 years in Shandong Province. Prevalence and characteristics of dyslipidemia were demonstrated. The odds ratios between dyslipidemia types and lipid-related diseases were further analyzed by logistic regression. Among the overall population, 45.8 % suffered from dyslipidemia. The prevalence of lipid abnormality (including high and very high levels) was 18.6, 12.7, 9.8 and 12.7 % for total cholesterol (TC), high-density lipoprotein (HDL), and low-density lipoprotein (LDL) cholesterol and triglycerides (TG), respectively. Among all participants with dyslipidemia, 23.9 % were aware, only 11.5 % were treated, 10.0 % were controlled. For subjects with dyslipidemia, the risk for non-alcoholic fatty liver disease (NAFLD) was highest with a 3.3-fold over that of non-dyslipidmia (OR = 3.30, P < 0.001); followed by hyperuricemia and diabetes mellitus (DM), while with 2-fold increase (OR = 1.99, P < 0.001; OR = 1.92, P < 0.001); with only 1.5-fold risk for atherosclerosis (AS) (OR = 1.47, P < 0.001). The presence of high cholesterol was mainly associated with AS, while abnormal TG was correlated with NAFLD and DM. Dyslipidemia has become a serious public health issue in rural North China. The rapid increase of high TC and incremental risk of high TG may contribute to the epidemic of AS, NAFLD and DM. It is imperative to develop individualized prevention and treatment guidelines according to dyslipidemia phenotypes.

Background The prevalence of dyslipidemia in multiple regions of Venezuela is unknown. The Venezuelan Metabolic Syndrome, Obesity and Lifestyle Study (VEMSOLS) was undertaken to evaluate cardiometabolic risk factors in Venezuela. Objective To determine the prevalence of dyslipidemia in five populations from three regions of Venezuela. Methods During the years 2006 to 2010, 1320 subjects aged 20 years or older were selected by multistage stratified random sampling from all households in five municipalities from 3 regions of Venezuela: Lara State (Western region), Merida State (Andean region), and Capital District (Capital region). Anthropometric measurements and biochemical analysis were obtained from each participant. Dyslipidemia was defined according to the NCEP/ATPIII definitions. Results Mean age was 44.8 ± 0.39 years and 68.5% were females. The prevalence of lipids abnormalities related to the metabolic syndrome (low HDL-c [58.6%; 95% CI 54.9 - 62.1] and elevated triglycerides [39.7%; 36.1 - 43.2]) were the most prevalent lipid alterations, followed by atherogenic dyslipidemia (25.9%; 22.7 - 29.1), elevated LDL-c (23.3%; 20.2 - 26.4), hypercholesterolemia (22.2%; 19.2 - 25.2), and mix dyslipidemia (8.9%; 6.8 - 11.0). Dyslipidemia was more prevalent with increasing body mass index. Conclusion Dyslipidemias are prevalent cardiometabolic risk factors in Venezuela. Among these, a higher prevalence of low HDL is a condition also consistently reported in Latin America. PMID:29538522

People with type 2 diabetes mellitus have a 2 to 4 times higher risk of developing cardiovascular diseases when compared to general population of similar age and sex. This risk remains after adjustment of other traditional cardiovascular risk factors. The dyslipidemia associated with type 2 diabetes mellitus is present in up to 60% of people with diabetes and contributes greatly to increased cardiovascular, morbidity and mortality risk in these patients. Diabetic dyslipidemia is a disorder of lipid metabolism characterized by an excess of triglycerides, a decrease in HDL-cholesterol and altered lipoprotein composition, consisting mainly in an excess of small, dense LDL particles. Multiple clinical trials have demonstrated the benefits of drug treatment of dyslipidemia (mainly statins) to prevent cardiovascular events and mortality in people with diabetes, both in primary and secondary prevention. This consensus document, developed by general practitioners, members of the Diabetes Group of the Spanish Society of Primary Care Physicians (SEMERGEN), aims to assist in the management of patients with diabetes and dyslipidemia in accordance with the most recent recommendations.

Dyslipidemia is a known risk factor for cardiovascular disease and is a leading cause of mortality in developed and developing countries. This study was aimed to determine the prevalence of dyslipidemia and its risk factors in an urban group of Iranian adult population. In this study, based on the criteria set by the National Cholesterol Education Program, the prevalence of dyslipidemia was evaluated in a population of 4737 people aged 45-69 years who participated in the second phase of an ophthalmology cohort study in Shahroud. Dyslipidemia prevalence was determined by age, sex, and risk factors of the disease; the findings were tested by using simple and multiple logistic regression. The prevalence of dyslipidemia was 66.5% (CI 95%: 64.4-68.6) in males, 61.3% (CI 95%: 59.5-63.2) in females, and 63.4% (CI 95%: 62.0-64.9%) in both sexes. The prevalence of hypertriglyceridemia, hypercholesterolemia, low HDL-C, and high LDL-C, respectively, was 28.8%, 13.4%, 42.3%, and 13.4%, respectively. In multivariate logistic regression model, increase of age (for females), abdominal obesity, overweight and obesity, hypertension, and diabetes were associated with an increased odd of dyslipidemia. The prevalence of dyslipidemia in middle-aged urban population in Iran is high, and with increasing age there is an increased risk of dyslipidemia. Hence, considering the growing trend of aging in Iran, there is need for taking special measures to deal with dyslipidemia as a health priority. Furthermore, the need for planning in order to reduce the risk of dyslipidemia and prevent its complications is greater than ever. Copyright © 2016 Diabetes India. Published by Elsevier Ltd.

We determined the prevalence of dyslipidemia in a Japanese cohort of renal allograft recipients and investigated clinical and genetic characteristics associated with having the disease. In total, 126 patients that received renal allograft transplants between February 2002 and August 2011 were studied, of which 44 recipients (34.9%) were diagnosed with dyslipidemia at 1 year after transplantation. Three clinical factors were associated with a risk of having dyslipidemia: a higher prevalence of disease observed among female than male patients (P = 0.021) and treatment with high mycophenolate mofetil (P = 0.012) and prednisolone (P = 0.023) doses per body weight at 28 days after transplantation. The genetic association between dyslipidemia and 60 previously described genetic polymorphisms in 38 putative disease-associated genes was analyzed. The frequency of dyslipidemia was significantly higher in patients with the glucocorticoid receptor (NR3C1) Bcl1 G allele than in those with the CC genotype (P = 0.001). A multivariate analysis revealed that the NR3C1 Bcl1 G allele was a significant risk factor for the prevalence of dyslipidemia (odds ratio = 4.6; 95% confidence interval = 1.8-12.2). These findings may aid in predicting a patient's risk of developing dyslipidemia.

The objective of the study was to determine the frequency and characteristics of dyslipidemia in patients with HIV in highly active antiretroviral therapy (HAART) in a Peruvian public hospital. A cross-sectional study was carried out in patients with complete lipid profile after receiving at least six months of HAART. Dyslipidemia was defined according to the criteria of the NCEP-ATP III. We reviewed 2 975 clinical histories, and included 538 (18.1%) in the analysis. The frequency of dyslipidemia was 74.7%. HAART regimens which include protease inhibitors (PI) (odds ratio [OR]: 1.22; confidence interval at 95% [CI 95%]: 1.11-1.33) and to be older than 40 years (OR: 1.17; CI 95%: 1.05-1.28) were associated with dyslipidemia, adjusted by viral load, CD4 lymphocyte level and gender. In conclusion, dyslipidemia was very common in our sample and was mainly associated with the use of PI. It is necessary to promote the dyslipidemia control as part of the comprehensive care of the patient with HIV.

Antisense therapy and emerging applications for the management of dyslipidemia.

Toth, Peter P

2011-01-01

Because a significant percentage of patients who require high-dose statin therapy for dyslipidemia experience treatment-related muscle symptoms and an inconsistent clinical response, alternative or adjunctive approaches to the management of dyslipidemia are needed. One alternative approach, antisense therapy, may offer an effective and well-tolerated option for patients not satisfactorily responsive to or intolerant to standard pharmacologic dyslipidemia therapies. This review provides an overview of antisense technology and its potential role in the management of dyslipidemia. Source material was obtained primarily from the published literature identified through a search of the PubMed database. Antisense technology is an evolving approach to therapy that has gone through a series of refinements to enhance molecular stability, potency, and tolerability. Mipomersen is an antisense molecule capable of producing clinically meaningful reductions in low-density lipoprotein cholesterol in patients with severe familial hypercholesterolemia. Further long-term clinical studies are required to more clearly quantify its impact on risk for cardiovascular events and establish whether it increases risk for hepatosteatosis. Antisense therapy represents a potentially effective and well-tolerated emerging treatment modality for numerous diseases. In the treatment of hypercholesterolemia, the antisense therapy mipomersen may provide a possible treatment option for patients with treatment-resistant dyslipidemia.

Dyslipidemia is a major risk factor for cardiovascular complications in people with diabetes. Lowering low-density lipoprotein cholesterol (LDL-C) levels is effective in the primary and secondary prevention of diabetic vascular complications. However, LDL-C levels do not reflect all aspects of diabetic dyslipidemia, which is characterized by hypertriglyceridemia and low high-density lipoprotein cholesterol (HDL-C). Statins, nicotinic acid, and fibrates play a role in treating diabetic dyslipidemia. Atherosclerosis is a major disorder of the blood vessel wall in patients with diabetes. A number of antihyperlipidemic agents may be beneficial and exhibit effects at the actual site of vascular disease and not only on plasma lipoprotein concentrations. Several novel therapeutic compounds are currently being developed. These include additional therapeutics for LDL-C, triglycerides, HDL-C, and modulators of inflammation that can be used as possible synergic agents for the treatment of atherosclerosis and irregularities in plasma lipoprotein concentrations.

No previous studies have evaluated the association between dyslipidemia, alcohol drinking, and diabetes in an Inner Mongolian population. We aimed to evaluate the co-effects of drinking and dyslipidemia on diabetes incidence in this population. The present study was based on 1880 participants from a population-based prospective cohort study among Inner Mongolians living in China. Participants were classified into four subgroups according to their drinking status and dyslipidemia. Multivariate logistic regression analysis and receiver operating characteristic (ROC) curves were used to evaluate the association between alcohol drinking, dyslipidemia, and diabetes. During the follow-up period, 203 participants were found to have developed diabetes. The multivariable-adjusted odds ratios (95% confidence interval) for the incidence of non-dyslipidemia/drinkers, dyslipidemia/non-drinkers, and dyslipidemia/drinkers in diabetic patients were 1.40 (0.82-2.37), 1.73 (1.17-2.55), and 2.31 (1.38-3.87), respectively, when compared with non-dyslipidemia/non-drinkers. The area under the ROC curve for a model containing dyslipidemia and drinking status along with conventional factors (AUC=0.746) was significantly (P=0.003) larger than the one containing only conventional factors (AUC=0.711). The present study showed that dyslipidemia was an independent risk factor for diabetes, and that drinkers with dyslipidemia had the highest risk of diabetes in the Mongolian population. These findings suggest that dyslipidemia and drinking status may be valuable in predicting diabetes incidence. Copyright © 2016 The Editorial Board of Biomedical and Environmental Sciences.

Studies indicate that dyslipidemia is undertreated. Numerous systematic reviews have shown that, even when therapeutic targets set by clinical practice guidelines have not been met, treatment remains unchanged despite the availability of alternatives approaches. The result is increased morbidity and mortality. Our aims were to investigate this phenomenon, known as therapeutic inertia, in patients with dyslipidemia and ischemic heart disease, and to determine its possible causes. national, multicenter, observational study of data obtained from physicians by questionnaire and from the clinical records of patients with ischemic heart disease. Main variable: therapeutic inertia during a consultation, defined as treatment remaining the same despite a change being indicated (e.g. low-density lipoprotein cholesterol >100 mg/dl or >70 mg/dl in diabetics). Covariates: physician, patient and consultation characteristics. multivariate logistic regression analysis of factors associated with therapeutic inertia during a consultation. Overall, 43% of consultations involved therapeutic inertia, and an association with coronary risk factors, including diabetes, did not result in a change in treatment. Therapeutic inertia occurred more frequently when there was a long time between the diagnosis and treatment of dyslipidemia and that of ischemic heart disease. Undertreatment was particularly common in women despite a greater overall risk. The more experienced physicians treated younger patients more appropriately. Clinical practice was improved by educational sessions at conferences. Therapeutic inertia was common in patients with chronic ischemic heart disease and dyslipidemia, irrespective of overall cardiovascular risk. Factors associated with the patient, disease and physician had an influence.

To investigate whether there is an association between job stress, lipid profile and dyslipidemia diagnosis. This study used a questionnaire to evaluate job stress and lifestyle variables in 91,593 workers undergoing periodic checkups. Serum lipid levels were measured in all cases. The prevalence of job stress was 8.7% (95% CI, 8.5-8.8%). In bivariate analyses, job stress was significantly associated with previous dyslipidemia diagnosis (p < 0.001), lipid-lowering therapy (p < 0.001), and altered total-cholesterol (p = 0.001), HDL-cholesterol (p < 0.001) and LDL-cholesterol levels (p = 0.025). After adjusting for potential confounding variables, job stress was still associated with current dyslipidemia diagnosis (OR = 1.10; 95% CI, 1.04-1.17), high LDL-cholesterol (OR = 1.14; 95% CI, 1.05-1.23), low HDL-cholesterol (OR 1.08; 95% CI, 1.01-1.15), high total cholesterol/HDL-cholesterol ratio (OR 1.13; 95% CI, 1.05-1.23) and high LDL-cholesterol/HDL-cholesterol ratio (OR 1.11; 95% CI, 1.04-1.19). These results support the hypothesis of an association between job stress and lipid disturbances.

Clustered regularly interspaced short palindromic repeat (CRISPR)/CRISPR-associated 9 (Cas9) has recently emerged as a top genome editing technology and has afforded investigators the ability to more easily study a number of diseases. This review discusses CRISPR/Cas9's advantages and limitations and highlights a few recent reports on genome editing applications for alleviating dyslipidemia through disruption of proprotein convertase subtilisin/kexin type 9 (PCSK9). Targeting of mouse Pcsk9 using CRISPR/Cas9 technology has yielded promising results for lowering total cholesterol levels, and several recent findings are highlighted in this review. Reported on-target mutagenesis efficiency is as high as 90% with a subsequent 40% reduction of blood cholesterol levels in mice, highlighting the potential for use as a therapeutic in human patients. The ability to characterize and treat diseases is becoming easier with the recent advances in genome editing technologies. In this review, we discuss how genome editing strategies can be of use for potential therapeutic applications.

Tinnitus is a sense of sound perception in absence of an external source which can affect life quality. Different conditions may lead to tinnitus including metabolic disorders such as dyslipidemia. The aim of this study was to investigate the prevalence of dyslipidemia among Iranian patients with idiopathic tinnitus. This was a cross-sectional study in which prevalence of dyslipidemia in fasting state and its subclasses were assessed in 1043 tinnitus patients aged 12-90 years who referred to Rasool Akram Hospital, Tehran, Iran, 2006-2009. Data was summarized by SPSS software version 17 and one sample t-test and Chi-Square test were applied to analyze the results. P less than 0.05 were considered significant. The most prevalent type of dyslipidemia was hypercholesterolemia with the frequency of 14.4% followed by low HDL-C with the frequency of 12.8%. Mean of total cholesterol, HDL-C, LDL-C and triglyceride levels in all patients were not greater than general population. Based on the results of the present study, there might be no need to check the serum lipid profile in tinnitus patients. We recommend further studies to assess both fasting and postprandial serum lipid profile in patients with idiopathic tinnitus. Simultaneous investigation of their dietary intake is also suggested.

Diabetic retinopathy (DR) is one of the major microvascular complications of diabetes. In developed countries, it is the most common cause of preventable blindness in diabetic adults. Dyslipidemia, a major systemic disorder, is one of the most important risk factors for cardiovascular disease. Patients with diabetes have an increased risk of suffering from dyslipidemia concurrently. The aim of this article is to review the association between diabetic retinopathy (DR) and traditional/nontraditional lipid markers, possible mechanisms involving lipid metabolism and diabetic retinopathy, and the effect of lipid-lowering therapies on diabetic retinopathy. For traditional lipid markers, evidence is available that total cholesterol and low-density lipoprotein cholesterol are associated with the presence of hard exudates in patients with DR. The study of nontraditional lipid markers is advancing only in recently years. The severity of DR is inversely associated with apolipoprotein A1 (ApoA1), whereas ApoB and the ApoB-to-ApoA1 ratio are positively associated with DR. The role of lipid-lowering medication is to work as adjunctive therapy for better control of diabetes-related complications including DR. PMID:24380088

Dyslipidemia is an abnormal amount of lipids and/or lipoproteins in the blood. It is a major risk factor of coronary heart disease and atherosclerosis. This study investigated two single nucleotide polymorphisms (SNPs) in the apolipoprotein E receptor 2 (ApoER2) gene in association with risk of dyslipidemia in the Thai patients. Four hundred blood samples including dyslipidemia patient (200) and unrelated normal control (200) were included in this study. Serum lipids were examined. DNAs were extracted and genotyped by using polymerase chain reaction (PCR) followed by high-resolution melting (HRM) analysis. The differences in genotype distribution between patient and normal control were assessed by Chi-square test of the SPSS software version 11.5. The data analysis revealed that two SNPs (rs3737984 and rs2297660) in ApoER2 gene had significant association with dyslipidemia. The rs3 737984 showed significant association at p-value = 0.001, in which A alleles informed the decreased risk of dyslipidemia [odds ratio and 95% CI of A allele, 0.42 (0.28-0.65)]. In contrast, the rs2297660 exhibited strongest association with an increase risk ofdyslipidemia [p-value = 0.001, odds ratio and 95% CI for theA allele was 2.38 (1.49-3.80)]. The rs2297660 may be used as biomarker for the risk of dyslipidemia in Thai ethnic.

To assess the prevalence of dyslipidemia and lipodystrophy in Indian children receiving non-nucleoside reverse transcriptase inhibitor (NNRTI) based highly active antiretroviral therapy (HAART) and to determine the associated risk factors for the same. The present cross-sectional study was conducted at a Pediatric Clinic of a tertiary care teaching center in India, from May 2011 through December 2012. HIV infected children aged 5-15 y were enrolled if they did not have any severe disease or hospital admission within last 3 mo or receive any medications known to affect the lipid profile. Eighty-one children were on highly active antiretroviral therapy (HAART) for at least 6 mo and 16 were receiving no antiretroviral therapy (ART). Participants' sociodemographic, nutritional, clinical, and laboratory data were recorded in addition to anthropometry and evidence of lipodystrophy. Fasting lipid profile, apolipoprotein A1 and B levels were done for all the children. Among the children on highly active antiretroviral therapy (HAART), 38.3 % had dyslipidemia and 80.2 % had lipodystrophy, while 25 % antiretroviral therapy (ART) naïve HIV infected children had dyslipidemia. No clinically significant risk factors could be identified that increased the risk of dyslipidemia or lipodystrophy in children on highly active antiretroviral therapy (HAART). There is a high prevalence of dyslipidemia and lipodystrophy in Indian children with HIV infection with an imminent need to establish facilities for testing and treatment of these children for metabolic abnormalities.

Cardiovascular disease is the leading cause of death and disability worldwide. Therefore, as part of the Dyslipidemia International Study (DYSIS), we have analyzed the prevalence of lipid abnormalities and risk factors for dyslipidemia in statin-treated patients in Lebanon and Jordan. This cross-sectional, multicenter study enrolled 617 patients at 13 hospitals in Lebanon and Jordan. Patients were at least 45 years old and had been treated with statins for at least 3 months. Multivariate logistic regression analysis was used to determine patient characteristics contributing to dyslipidemia during statin therapy. Our findings indicated that 55.9% of statin-treated patients (mean age 60.3 years, 47% female) in Lebanon and Jordan did not achieve goal levels for low-density lipoprotein cholesterol which were dependent on Systematic Coronary Risk Evaluation (SCORE) risk, and 70% of patients (76% men and 63.3% of women) were at very high cardiovascular risk. Low-density lipoprotein cholesterol goals were not achieved in 67.2% of those with very high cardiovascular risk. The most commonly prescribed statin was atorvastatin (44.6%), followed by simvastatin (27.7%), rosuvastatin (21.2%), fluvastatin (3.3%), pravastatin (3%), and lovastatin (0.2%). Approximately half of the population was treated with a statin dose potency of 4, equaling 40 mg of simvastatin. In Lebanon and Jordan, the strongest independent associations with low-density lipoprotein cholesterol not at goal were current smoking (odds ratio [OR] 1.96; 95% confidence [CI] 1.25-3.08), diabetes mellitus (OR 2.53; 95% CI 1.70-3.77), and ischemic heart disease (OR 2.26; 95% CI 1.45-3.53), while alcohol consumption was associated with reduced risk (OR 0.12; 95% CI 0.03-0.57). We observed that many patients in Lebanon and Jordan experienced persistent dyslipidemia during statin treatment, supporting the notion that novel lipid-lowering strategies need to be developed. Also, social programs aimed at combating the

Obesity is associated with development of diverse diseases, including cardiovascular diseases and dyslipidemia. MiRNA-22 (miR-22) is a critical regulator of cardiac function and targets genes involved in metabolic processes. Previously, we generated miR-22 null mice and we showed that loss of miR-22 blunted cardiac hypertrophy induced by mechanohormornal stress. In the present study, we examined the role of miR-22 in the cardiac and metabolic alterations promoted by high-fat (HF) diet. We found that loss of miR-22 attenuated the gain of fat mass and prevented dyslipidemia induced by HF diet, although the body weight gain, or glucose intolerance and insulin resistance did not seem to be affected. Mechanistically, loss of miR-22 attenuated the increased expression of genes involved in lipogenesis and inflammation mediated by HF diet. Similarly, we found that miR-22 mediates metabolic alterations and inflammation induced by obesity in the liver. However, loss of miR-22 did not appear to alter HF diet induced cardiac hypertrophy or fibrosis in the heart. Our study therefore establishes miR-22 as an important regulator of dyslipidemia and suggests it may serve as a potential candidate in the treatment of dyslipidemia associated with obesity. © 2017 The Author(s).

Cardiovascular disease is the most common cause of morbidity and mortality in patients with diabetes and the major source of cost in the care of diabetes. Treatment of dyslipidemia with cholesterol-lowering medications has been shown to decrease cardiovascular events. However, available guidelines for the treatment of dyslipidemia often contain significant differences in their recommendations. Lipid guidelines from National Cholesterol Education Program Adult Treatment Panel III, American Association of Clinical Endocrinologists, American Diabetes Association and American Heart Association/American College of Cardiology were reviewed. In addition a literature review was performed using PubMed to research diabetic peculiarities to the topic of lipids. Summarized within this article are the aforementioned, commonly-used guidelines as they relate to diabetes, as well as information regarding the diabetic phenotype of dislipidemia and the association between statins and new-onset diabetes. While the multitude of guidelines and the differences between them may contribute to confusion for practitioners, they are best viewed as tools to help tailor appropriate treatment plans for individual patients.

Although several studies suggest a possible link between dyslipidemia and atopy, literature findings are still unclear. The aim of the study was to investigate the relationship between dyslipidemia and atopy in a pediatric population affected by dyslipidemia or dyslipidemia/atopic predisposition. Children with dyslipidemia, dyslipidemia and atopy as well as healthy children were recruited. Serum total IgE, IL-10, IL-17, and IL-23 levels as well as fasting lipid values (total cholesterol, LDL, HDL and triglycerides) were performed on all enrolled children. The present study evaluated 23 patients affected by dyslipidemia, 26 patients affected by atopy and dyslipidemia and, 22healthy children. Serum total IgE levels significantly related also with serum cholesterol levels: positively with total cholesterol (p<0.05), LDL (p<0.05), and tryglicerides (p<0.001), but negatively with HDL (p<0.05). Serum levels of IL-10 were lower in children with atopy and dyslipidemia than patients with dyslipidemia (p<0.001). Serum IL-10 levels significantly related also with serum cholesterol levels: negatively with total cholesterol (p<0.001), LDL (p<0.05), and triglycerides (p<0.05), but positively with HDL (p<0.05). Serum IL-17 and IL-23 levels showed the same trend. They were significantly higher in children with atopy and dyslipidemia than patients with dyslipidemia (p<0.001). In particular, serum IL-17 and IL-23 values positively correlated with serum total IgE levels (p<0.05); serum total cholesterol levels (p<0.001); serum LDL levels (p<0.001); serum triglycerides levels (p<0.05). Although not statistically significant, an inverse correlation has been noted between serum IL-17, IL-23 and HDL levels. These findings support the notion that dyslipidemia and atopic predisposition share the same immune pathways as well as they offer new insights in the complex crosstalk between hyperlipidemia and atopy.

The purpose of this review is to discuss dyslipidemia in the various common clinical conditions including hypertension, diabetes mellitus, and metabolic syndrome and review the current therapeutic strategy in these settings. Dyslipidemias are common in patients with hypertension, diabetes mellitus, and metabolic syndrome. Epidemiologic studies have shown a strong correlation between serum lipid levels and risk of atherosclerotic cardiovascular disease. Multifactorial intervention strategies aimed at controlling lipids, blood pressure, and blood glucose simultaneously achieve maximal reductions in cardiovascular risk. Dyslipidemia and metabolic abnormalities are strongly associated with atherosclerosis and worse cardiovascular outcomes. While pharmacotherapy with statins has been proven to be beneficial for dyslipidemia, lifestyle modification emphasizing weight loss and regular exercise is an essential component of the interventional strategy. The common thread underlying atherosclerosis and metabolic abnormalities is endothelial dysfunction. Improved understanding of the role of endothelium in health and disease can potentially lead to novel therapies that may preempt development of atherosclerosis and its complications.

The use of medications for the treatment of dyslipidemia is relevant in the control of cardiovascular disease. This article aims to analyze the prevalence, the use and the participation of the public sector in the supply of medication for adults aged 40 years and above using pharmacotherapy for dyslipidemia control living in a city in the southern region of Brazil. A cross-sectional, population-based study was conducted. Household interviews were staged with 1180 individuals aged over 40 living in Cambé, State of Paraná, of which 967 took laboratory examinations. The prevalence of dyslipidemia was 69.2%, of which 16.1% were taking medication. Among individuals undergoing treatment for dyslipidemia, 22.2% had adequate test results. Lipid-lowering medication used were simvastatin (81.5%) and bezafibrate (6.5%), mainly obtained by direct payment to private pharmacies and drug stores (52.2%) and NHS services (33.6%). A high prevalence of dyslipidemias was observed in population terms, together with a low level of dyslipidemia control and low participation of the public sector regarding the supply of medication compared to acquisition through direct payment for medication in private pharmacies. These results suggest a limited range of public policy for control of dyslipidemia.

In non-dialysis chronic kidney disease (CKD) patients with dyslipidemia, statin therapy is recommended to prevent cardiovascular complications. Dyslipidemia has been also shown to be an independent risk factor for the progression of CKD. However, it is still unclear whether statin therapy exerts an inhibitory effect on renal deterioration in CKD patients with dyslipidemia. The purpose of the present study was to examine possible therapeutic effects of statin add-on therapy on renal function as well as parameters of lipid and glucose metabolism, arterial stiffness and oxidative stress, in comparison to diet therapy, in CKD patients with dyslipidemia. This study was a randomized, open-label, and parallel-group trial consisted of a 12-months treatment period in non-dialysis CKD patients with alubuminuria and dyslipidemia. Twenty eight patients were randomly assigned either to receive diet counseling alone (diet therapy group) or diet counseling plus pitavastatin (diet-plus-statin therapy group), to achieve the LDL-cholesterol (LDL-C) target of <100 mg/dl. The statin treatment by pitavastatin was well tolerated in all of the patients without any significant adverse events and the average dose of pitavastatin was 1.0 ± 0.0 mg daily after treatment. After the 12-months treatment period, LDL-C was significantly lower in the diet-plus-statin therapy group compared with the diet therapy group (diet vs diet-plus-statin: LDL-C, 126 ± 5 vs 83 ± 4 mg/dL, P < 0.001). On the other hand, the diet-plus-statin therapy did not significantly reduce albuminuria or delay the decline in eGFR compared with the diet therapy, and there was no relationship between the change in LDL-C and the change in eGFR or albuminuria. However, diet therapy as well as diet-plus-statin therapy exerted similar lowering effects on the pentosidine levels (diet therapy group, baseline vs 12 months: 40 ± 4 vs 24 ± 3 ng/mL, P = 0.001; diet-plus-statin therapy, 46 ± 7 vs 34�

Aim. This study aimed to analyze blood lipid levels, temporal trend, and age distribution of dyslipidemia in civil aviators in China. Methods. The 305 Chinese aviators were selected randomly and followed up from 2006 to 2011. Their total cholesterol (TC), triglyceride (TG), high-density lipoprotein cholesterol (HDL-C), and low-density lipoprotein cholesterol (LDL-C) levels were evaluated annually. Mean values for each parameter by year were compared using a linear mixed-effects model. The temporal trend of borderline high, high, and low status for each index and of overall borderline high, hyperlipidemia, and dyslipidemia by year was tested using a generalized linear mixed model. Results. The aviators' TC (F = 4.33, P < 0.01), HDL-C (F = 23.25, P < 0.01), and LDL-C (F = 6.13, P < 0.01) values differed across years. The prevalence of dyslipidemia (F = 5.53, P < 0.01), borderline high (F = 6.52, P < 0.01), and hyperlipidemia (F = 3.90, P < 0.01) also differed across years. The prevalence rates for hyperlipidemia and dyslipidemia were the highest in the 41–50-year-old and 31–40-year-old groups. Conclusions. Civil aviators in China were in high dyslipidemia and borderline high level and presented with dyslipidemia younger than other Chinese populations. PMID:24693285

Across the globe, human immunodeficiency virus (HIV) infection is a healthcare problem. Dyslipidemia, a cardiovascular risk factor, is known to occur with the progression of HIV infection. The factors which influence dyslipidemia in HIV subjects have not been completely identified. The aim of this study was to evaluate serum lipids and identify the factors which might influence dyslipidemia in treatment-naïve HIV subjects in Owerri, Nigeria. This was a cross-sectional study of treatment-naïve HIV subjects. Anthropometric and demographic data were collected. Serum LDL serum cholesterol, serum high density lipoprotein cholesterol, serum triglyceride, spot urine creatinine, spot urine osmolality, spot urine protein, serum creatinine, 24-hour urine protein, 24-hour urine osmolality, 24-hour urine creatinine, creatinine clearance and hemoglobin were conducted. The variables were compared between those who have dyslipidemia and those who have no dyslipidemia. The mean age of the subjects was 39 ± 11 years. Females constituted 72.0% and males 28.0%. Elevated serum LDL was present in 17.6%, elevated serum total cholesterol in 11.4%, elevated serum triglyceride in 9.9% and low serum HDL in 34.4% of the subjects. There was significant association between dyslipidemia and CD4 cells count, as well as anemia. There was no significant association between dyslipidemia and urine protein, urine creatinine, urine osmolality, creatinine clearance, as well as 24-hour urine volume. The prevalence of dyslipidemia was high in the study subjects. Abnormal CD4 cells count and anemia were common in treatment-naïve HIV subjects who have dyslipidemia.

Low cardiorespiratory fitness has been established as a risk factor for cardiovascular-related morbidity. However, research about the impact of fitness on lipid abnormalities, including atherogenic dyslipidemia, has produced mixed results. The purpose of this investigation is to examine the influence of baseline fitness and changes in fitness on the development of atherogenic dyslipidemia. All participants completed at least 3 comprehensive medical examinations performed by a physician that included a maximal treadmill test between 1976 and 2006 at the Cooper Clinic in Dallas, Texas. Atherogenic dyslipidemia was defined as a triad of lipid abnormalities: low high-density-lipoprotein cholesterol ([HDL-C] <40 mg/dL), high triglycerides ([TGs] ≥200 mg/dL), and high low-density-lipoprotein cholesterol ([LDL-C] ≥160 mg/dL). A total of 193 participants developed atherogenic dyslipidemia during an average of 8.85 years of follow-up. High baseline fitness was protective against the development of atherogenic dyslipidemia in comparison with those with low fitness (odds ratio [OR] 0.57; 95% confidence interval [CI], 0.37-0.89); however, this relationship became nonsignificant after controlling for baseline HDL-C, LDL-C, and TG levels. Participants who maintained fitness over time had lower odds of developing atherogenic dyslipidemia than those with a reduction in fitness (OR 0.56; 95% CI, 0.34-0.91) after adjusting for baseline confounders and changes in known risk factors. High fitness at baseline and maintenance of fitness over time are protective against the development of atherogenic dyslipidemia. Copyright © 2016 Elsevier Inc. All rights reserved.

Medications not intended for treatment of dyslipidemias and with a variable effect on lipids.

PubMed

Whayne, Thomas F; Mukherjee, Debabrata

2014-01-01

Many therapeutically active medications have significant side effects, some of which can compromise the intended therapeutic goal. The development of plasma lipid abnormalities or a dyslipidemia as the result of a medication intended for an unrelated effect has been reported. Human immunodeficiency virus (HIV) infection can cause dyslipidemia as can the medications used to treat this infection. Such dyslipidemia can be a significant problem made more relevant by the already increased risk of cardiovascular (CV) disease faced by these patients. Some hypoglycemic medications used to treat diabetes can also be associated with dyslipidemia, most notably rosiglitazone. Antihypertensive medications are intended to decrease CV risk but are not free of dyslipidemia problems with thiazides able to cause hypertriglyceridemia and older beta-blockers without an alpha-blocking effect associated with moderate plasma lipid abnormalities and altered glucose metabolism. Estrogen administered orally can be associated with a severe hypertriglyceridemia. Currently-used antipsychotic medications have a significant association with hypertriglyceridemia. Clinicians must be aware of the dyslipidemias caused by these medications and know how to manage them, even treating a secondary dyslipidemia with another medication as in the case of HIV infection rather than trying to switch treatment of the infection in many cases. Mention is also made of lipid lowering effects of medications intended for other purposes (e.g. angiotensin receptor blockers and orlistat).

Dyslipidemia increases the frequency and severity of micro and macrovascular complications of type 1 diabetes (T1D). The present study aims to determine the prevalence of dyslipidemia and its association with clinical and laboratory findings in diabetic children and adolescents. The study included 202 children and adolescents with T1D. Demographic data and laboratory findings were obtained from patients files. Dyslipidemia prevalence was found to be 26.2%. Hypercholesterolemia (15.8%) and hyperglyceridemia (12.9%) were most common findings. Age, body mass index (BMI), hemoglobin A1c (A1C) and poor metabolic control were significantly higher in cases with dyslipidemia. Smoking rate was 14.1% in the pubertal group. Poor metabolic control and dyslipidemia was found higher among smokers (p<0.05). Blood lipid levels should be monitored regularly and nutrition education should be repeated periodically to prevent and control dyslipidemia in patients with T1D. Smoking-related risks should be a part of patient education in the pubertal period.

In Lebanon and Jordan, the strongest independent associations with low-density lipoprotein cholesterol not at goal were current smoking (odds ratio [OR] 1.96; 95% confidence [CI] 1.25–3.08), diabetes mellitus (OR 2.53; 95% CI 1.70–3.77), and ischemic heart disease (OR 2.26; 95% CI 1.45–3.53), while alcohol consumption was associated with reduced risk (OR 0.12; 95% CI 0.03–0.57). Conclusion We observed that many patients in Lebanon and Jordan experienced persistent dyslipidemia during statin treatment, supporting the notion that novel lipid-lowering strategies need to be developed.

Current study was designed to investigate the effects of obstructive sleep apnea (OSA) combined dyslipidemia on the prevalence of atherosclerotic cardiovascular diseases (ASCVD). This was a cross-sectional study and subjects with documented dyslipidemia and without previous diagnosis of OSA were enrolled. Polysomnography was applied to evaluate apnea-hypopnea index (AHI). Based on AHI value, subjects were classified into four groups: without OSA, mild, moderate and severe OSA groups. Clinical characteristics and laboratory examination data were recorded. Relationship between AHI event and lipid profiles was analyzed, and logistic regression analysis was used to evaluate the effects of OSA combined dyslipidemia on ASCVD prevalence. Totally 248 subjects with dyslipidemia were enrolled. Compared to the other 3 groups, subjects with severe OSA were older, male predominant and had higher smoking rate. In addition, subjects with severe OSA had higher body mass index, waist-hip ratio, blood pressure, and higher rates of overweight and obesity. Serum levels of fasting plasma glucose, glycated hemoglobin, LDL-C and CRP were all significantly higher. ASCVD prevalence was considerably higher in subjects with severe OSA. AHI event in the severe OSA group was up to 35.4 ± 5.1 events per hour which was significantly higher than the other groups (P < 0.05 for trend). Pearson correlation analysis showed that only LDL-C was positively correlated with AHI events (r = 0.685, P < 0.05). Logistic regression analysis revealed that in unadjusted model, compared to dyslipidemia plus no-OSA group (reference group), OSA enhanced ASCVD risk in subjects with dyslipidemia, regardless of OSA severity. After extensively adjusted for confounding variables, the odds of dyslipidemia plus mild-OSA was reduced to insignificance. While the effects of moderate- and severe-OSA on promoting ASCVD risk in subjects with dyslipidemia remained significant, with severe-OSA most prominent (odds ratio: 1

Emerging data point the crosstalk between dyslipidemia and renin-angiotensin system (RAS). Advanced dyslipidemia is described to induce RAS activation in the vasculature. However, the interplay between early dyslipidemia and the RAS remains unexplored. Knowing that hamsters and humans have a similar lipid profile, we investigated the effects of early and advanced dyslipidemia on angiotensin II-induced contraction. Cumulative concentration-response curves for angiotensin II (1.0pmol/l to 1.0µmol/l) were obtained in the hamster thoracic aorta. We also investigated the modulatory action of NAD(P)H oxidase on angiotensin II-induced contraction using ML171 (Nox-1 inhibitor, 0.5µmol/l) and VAS2870 (Nox-4 inhibitor, 5µmol/l). Early dyslipidemia was detected in hamsters treated with a cholesterol-rich diet for 15 days. Early dyslipidemia decreased the contraction induced by angiotensin II and the concentration of Nox-4-derived hydrogen peroxide. Advanced dyslipidemia, observed in hamsters treated with cholesterol-rich diet for 30 days, restored the contractile response induced by angiotensin II by compensatory mechanism that involves Nox-4-mediated oxidative stress. The hyporresponsiveness to angiotensin II may be an auto-inhibitory regulation of the angiotensinergic function during early dyslipidemia in an attempt to reduce the effects of the upregulation of the vascular RAS during the advanced stages of atherogenesis. The recovery of vascular angiotensin II functionality during the advanced phases of dyslipidemia is the result of the upregulation of redox-pro-inflammatory pathway that might be most likely involved in atherogenesis progression rather than in the recovery of vascular function. Taken together, our findings show the early phase of dyslipidemia may be the most favorable moment for effective atheroprotective therapeutic interventions. Copyright © 2016 Elsevier B.V.

Aim The aim of this study was to estimate the prevalence, awareness, treatment, and control of dyslipidemia in Xinjiang, China. Method Stratified sampling method was used to select a representative sample of the general population including Chinese Han, Uygur, and Kazak in this geographic area. Seven cities were chosen. Based on the government records of registered residences, one participant was randomly selected from each household. The eligibility criterion for the study was ≥ 35 years of age. Results A total of 14,618 participants (5,757 Han, 4,767 Uygur, and 4,094 Kazak), were randomly selected from 26 villages in 7 cities. The prevalence of dyslipidemia was 52.72% in the all participants. The prevalence of dyslipidemia was higher in Han than that in the other two ethnic (58.58% in Han, 48.27% in Uygur, and 49.60% in Kazak, P < 0.000). The prevalence of dyslipidemia was higher in men than that in women (56.4% vs. 49.3%, P < 0.000). Among the participants with dyslipidemia, the proportion of those who aware, treat, control of dyslipidemia were 53.67%, 22.51%, 17.09% in Han, 42.19%, 27.78%, 16.20% in Uygur, 37.02%, 21.11%, 17.77% in Kazak. Conclusion Dyslipidemia is highly prevalent in Xinjiang. The proportion of participants with dyslipidemia who were aware, treated, and controlled is unacceptably low. These results underscore the urgent need to develop national strategies to improve the prevention, detection, and treatment of dyslipidemia in Xinjiang. PMID:24393232

Dyslipidemia in HIV-infected patients is unique and pathophysiologically associated with host factors, HIV itself and the use of antiretroviral therapy (ART). The use of nuclear magnetic resonance spectroscopy (NMR) provides additional data to conventional lipid measurements concerning the number of lipoprotein subclasses and particle sizes. To investigate the ability of lipoprotein profile, we used a circulating metabolomic approach in a cohort of 103 ART-naive HIV-infected patients, who were initiating non-nucleoside analogue transcriptase inhibitor (NNRTI)-based ART, and we subsequently followed up these patients for 36 months. Univariate and multivariate analyses were performed to evaluate the predictive power of NMR spectroscopy. VLDL-metabolism (including VLDL lipid concentrations, sizes, and particle numbers), total triglycerides and lactate levels resulted in good classifiers of dyslipidemia (AUC 0.903). Total particles/HDL-P ratio was significantly higher in ART-associated dyslipidemia compared to ART-normolipidemia (p = 0.001). Large VLDL-Ps were positively associated with both LDL-triglycerides (ρ 0.682, p < 0.001) and lactate concentrations (ρ 0.416, p < 0.001), the last one a marker of mitochondrial low oxidative capacity. Our data suggest that circulating metabolites have better predictive values for HIV/ART-related dyslipidemia onset than do the biochemical markers associated with conventional lipid measurements. NMR identifies changes in VLDL-P, lactate and LDL-TG as potential clinical markers of baseline HIV-dyslipidemia predisposition. Differences in circulating metabolomics, especially differences in particle size, are indicators of important derangements of mitochondrial function that are linked to ART-related dyslipidemia.

It has been shown that obesity is associated with increased rates of dyslipidemia. The present work revisits the association between plasma lipid levels and classical indicators of obesity including body mass index (BMI). The significance of various anthropometric/metabolic variables in clinical assessment of type and severity of dyslipidemia was also determined. Recently described body indices, a body shape index (ABSI) and body roundness index (BRI), were also assessed in this context. For the present cross-sectional analytical study, the participants (n = 275) were recruited from the patients visiting different health camps. Participants were anthropometrically measured and interviewed, and their fasting intravenous blood was collected. Plasma lipid levels were accordingly determined. The values for different anthropometric parameters are significantly different between dyslipidemic and non-dyslipidemic participants. Receiver operating characteristics curve analyses revealed that all the tested variables gave the highest area under the curve (AUC) values for predicting hypertriglyceridemia in comparison to other plasma lipid abnormalities. BRI gave slightly higher AUC values in predicting different forms of dyslipidemia in comparison to BMI, whereas ABSI gave very low values. Several anthropometric/metabolic indices display increased predictive capabilities for detecting hypertriglyceridemia in comparison to any other form of plasma lipid disorders. The capacity of BRI to predict dyslipidemia was comparable but not superior to the classical indicators of obesity, whereas ABSI could not detect dyslipidemia.

Drug-related problems in type 2 diabetes mellitus patients with dyslipidemia

2013-01-01

Background Drug-Related Problems (DRPs) commonly occur among type 2 diabetes mellitus (T2DM) patients. However, few studies have been performed on T2DM patients with dyslipidemia. This purpose of this study was to assess drug-related problems (DRPs) and factors associated with its occurrence. Methods The retrospective study involved 208 T2DM in-patients and out-patients with dyslipidemia, and was conducted at a tertiary hospital in Malaysia from January 2009 to December 2011. The identification and assessment of DRPs were based on the Pharmaceutical Care Network Europe (PCNE) tool version 5.01. The potentially inappropriate medication use in older adults was assessed based on the American Geriatrics Society updated Beers Criteria. Results A total of 406 DRPs were identified. Among these patients, 91.8% had at least one DRP, averaging 1.94 ± 1.10 problems per patient. The majority of T2DM patients with dyslipidemia (91.8%) had at least one DRP. The most frequent types of DRP were potential drug-drug interaction (18.0%), drug not taken or administered (14.3%) and insufficient awareness of health and diseases (11.8%). Anti-hypertensive, lipid-modifying and anti-diabetic agents were the drug classes that were most likely to be associated with DRPs. Male gender, renal impairment, polypharmacy and poor lipid control were factors that were significantly associated with DRP in diabetic dyslipidemia patients. Conclusion Early identification of DRPs and factors associated with them are essential to prevent and resolve DRPs in T2DM patients with dyslipidemia. PMID:24341672

To analyze the predictive capacity of anthropometric indicators and their cut-off values for dyslipidemia screening in children and adolescents. This was a cross-sectional study involving 1139 children and adolescents, of both sexes, aged 6-18 years. Body weight, height, waist circumference, subscapular, and triceps skinfold thickness were measured. The body mass index and waist-to-height ratio were calculated. Children and adolescents exhibiting at least one of the following lipid alterations were defined as having dyslipidemia: elevated total cholesterol, low high-density lipoprotein, elevated low-density lipoprotein, and high triglyceride concentration. A receiver operating characteristic curve was constructed and the area under the curve, sensitivity, and specificity was calculated for the parameters analyzed. The prevalence of dyslipidemia was 62.1%. The waist-to-height ratio, waist circumference, subscapular, body mass index, and triceps skinfold thickness, in this order, presented the largest number of significant accuracies, ranging from 0.59 to 0.78. The associations of the anthropometric indicators with dyslipidemia were stronger among adolescents than among children. Significant differences between accuracies of the anthropometric indicators were only observed by the end of adolescence; the accuracy of waist-to-height ratio was higher than that of subscapular (p=0.048) for females, and the accuracy of waist circumference was higher than that of subscapular (p=0.029) and body mass index (p=0.012) for males. In general, the cut-off values of the anthropometric predictors of dyslipidemia increased with age, except for waist-to-height ratio. Sensitivity and specificity varied substantially between anthropometric indicators, ranging from 75.6 to 53.5 and from 75.0 to 50.0, respectively. The anthropometric indicators studied had little utility as screening tools for dyslipidemia, especially in children. Copyright © 2015 Sociedade Brasileira de Pediatria

Background . Dyslipidemia and diabetes are two of the most well established risk factors for the development of cardiovascular disease (CVD). Both of them usually activate a complex range of pathogenic pathways leading to organ damage. Here we hypothesized that dyslipidemia and diabetes could affect osteoprotegerin (OPG) and TNF-related apoptosis-inducing ligand (TRAIL) expression in the vessels and the heart. Materials and Methods . Gene and protein expression of OPG, TRAIL, and OPG/TRAIL ratio were quantified in the aorta and the hearts of control mice, dyslipidemic mice, and diabetic mice. Results . Diabetes significantly increased OPG and the OPG/TRAIL ratio expression in the aorta, while dyslipidemia was the major determinant of the changes observed in the heart, where it significantly increased OPG and reduced TRAIL expression, thus increasing cardiac OPG/TRAIL ratio. Conclusions . This work shows that both dyslipidemia and diabetes affect OPG/TRAIL ratio in the cardiovascular system. This could contribute to the changes in circulating OPG/TRAIL which are observed in patients with diabetes and CVD. Most importantly, these changes could mediate/contribute to atherosclerosis development and cardiac remodeling.

To evaluate low-density lipoprotein-cholesterol (LDLc) achieved in patients with genetic dyslipidemia treated during one year in Lipid and Vascular Risk Units (LVRU) of the Spanish Society of Arteriosclerosis (SSA). Observational, longitudinal, retrospective, multicenter national study that included consecutive patients of both sexes over 18 years of age referred due to dyslipidemia to LVRU of the SSA. Information was collected from medical records corresponding to two visits in the lipid unit. A total of 527 patients (mean age 48 years, 60.0% men) diagnosed with genetic dyslipidemia (241 with heterozygous familial hypercholesterolemia, and 286 with familial combined hyperlipidemia) were included. The mean follow-up was 12.9 months. In the last visit, 94% were taking statins, one third combined with ezetimibe, although only 41% were taking a high-intensity hypolipidemic treatment. Overall, 28.5% of patients attained an LDLc level<100 mg/dL, 35.8% decreased their LDLc by >50%, and 53.8% achieved one of the two. Predictors of target LDLc levels in the multivariate analysis were age, smoking habit and the presence of vascular disease. Over half of the patients with genetic dyslipidemia followed up by LVRU of SSA achieve LDLc objectives after one year of follow-up. The use of high-intensity hypolipidemic treatment could improve these results. Copyright © 2014 Sociedad Española de Arteriosclerosis. Published by Elsevier España. All rights reserved.

In China, even though the prevalence of dyslipidemia among adults increased yearly and dyslipidemia being an important risk factor for cardiovascular diseases among the Chinese population, however, the awareness, treatment and control of dyslipidemia are at low levels, and only limited studies on the influence factors associated with the awareness, treatment and control dyslipidemia in China have been carried out. The analysis was based on a representative sample of 7138 adult subjects aged 18~79 years recruited from a cross-sectional study of chronic disease and risk factors among adults in the Jilin province in 2012. Chi-square test was used to compare the rates of dyslipidemia awareness, treatment and control between different characteristics of participants. Multiple logistic regression analyses were performed separately for each group to explore the associations between participants' characteristics and dyslipidemia awareness, treatment and control. Among participants with dyslipidemia, 11.6% were aware of the diagnosis, 8.4% were receiving treatment, and 34.8% had dyslipidemia controlled. Increase in age and BMI ≥ 24 kg/m2 were by far the strongest risk factors associated with better awareness and treatment of dyslipidemia. Retirees were more likely to be aware of their dyslipidemia condition (OR=1.255; 95% CI: 1.046, 1.506) and to be receiving treatment (OR=1.367; 95% CI: 1.114, 1.676) than manual workers. A family history of dyslipidemia increased the likelihood of awareness (OR=3.620; 95% CI: 2.816, 4.653) and treatment (OR=3.298; 95% CI: 2.488, 4.371) of dyslipidemia.

Diabetic dyslipidemia has specifics that differ from dyslipidemia in patients without diabetes, which contributes to accelerated atherosclerosis equally as dysglycemia. The aim of this study was to deduce the interdependence of diabetic dyslipidemia and cardiovascular diseases (CVD), therapeutic strategies and the risk of diabetes development with statin therapy. We conducted a literature review of English articles through PubMed, PubMed Central and Cochrane, on the role of diabetic dyslipidemia in atherosclerosis, the antilipemic treatment with statins, and the role of statin therapy in newly developed diabetes, by using key words: atherosclerosis, diabetes mellitus, diabetic dyslipidemia, CVD, statins, nicotinic acid, fibrates, PCSK9 inhibitors. hyperglycemia and dyslipidemia cannot be treated separately in patients with diabetes. It seems that dyslipidemia plays one of the key roles in the development of atherosclerosis. High levels of TG, decreased levels of HDL-C and increased levels of small dense LDL- C particles in the systemic circulation are the most specific attributes of diabetic dyslipidemia, all of which originate from an inflated flux of free fatty acids occurring due to the preceding resistance to insulin, and exacerbated by elevated levels of inflammatory adipokines. Statins are a fundamental treatment for diabetic dyslipidemia, both for dyslipidemia and for CVD prevention. The use of statin treatment with high intensity is endorsed for all diabetes-and-CVD patients, while a moderate - intensity treatment can be applied to patients with diabetes, having additional risk factors for CVD. Statins alone are thought to possess a small, although of statistical significance, risk of incident diabetes, outweighed by their benefits. As important as hyperglycemia and glycoregulation are in CVD development in patients with diabetes, diabetic dyslipidemia plays an even more important role. Statins remain the cornerstone of antilipemic treatment in diabetic

Venous and arterial thrombosis, despite being historically considered as distinct conditions, share certain risk factors. Dyslipidemia is a clinical condition with a relatively high prevalence in the population and has been associated with an increased thrombotic risk. Lipids and lipoproteins modulate the expression and/or function of thrombotic, fibrinolytic and rheological factors. We have developed a descriptive, retrospective, comparative, cross-sectional study including a group of 313 patients with venous thromboembolism (VTE). We collected basic demographic data, cardiovascular risk factors and thrombotic complications. All patients were subjected to a lipid profile study with determination of total cholesterol, high density lipoprotein cholesterol (cHDL), low density lipoprotein cholesterol (cLDL) and triglycerides. The multivariable analysis showed that dyslipidemia was a risk factor for VTE (odds ratio [OR] 3.87, 95% confidence interval [95% CI] 2.72-5.56; P<.0001). Of a total of 313 patients included in the study, 31% (n=97) had a recurrent thrombotic event and 23% (n=72) developed post-thrombotic syndrome. cHDL levels below 35 mg/dl and cLDL levels higher than 180 mg/dl represented risk factors for the development of recurrent thrombosis, OR 3.12 (95% CI 1.35-7.74; P=.008) and OR 2.35 (95% CI 1.24-4.45; P=.008), respectively, and post-thrombotic syndrome, OR 3.44 (95% CI 1.43-8.83; P=.005) and OR 2.35 (95% CI 1.24-4.45; P=.008). Our study confirmed the association between dyslipidemia and VTE and showed a risk of thrombosis nearly 4 times higher in individuals with this disease. In addition, alterations in the lipid profile were also related to a higher prevalence of thrombotic complications, recurrence and post-thrombotic syndrome. Copyright © 2013 Elsevier España, S.L.

Abstract Little is known about the epidemiological features of dyslipidemia among antiretroviral-naive HIV-infected individuals in China. We used a cross-sectional study design to estimate the prevalence of dyslipidemia in this population, and to identify risk factors associated with the presence of dyslipidemia. One thousand five hundred and eighteen antiretroviral-naive HIV-infected individuals and 347 HIV-negative subjects in China were enrolled during 2009 to 2010. Demographics and medical histories were recorded. After an overnight fast, serum samples were collected to measure lipid levels. Factors associated with the presence of dyslipidemia were analyzed by logistic regression. Mean total cholesterol (TC), low-density lipoprotein cholesterol (LDL), high-density lipoprotein cholesterol (HDL) levels were lower in HIV-positive than HIV-negative subjects, but mean triglyceride (TG) was higher in HIV-positive subjects. The overall prevalence of dyslipidemia in HIV-positive and HIV-negative groups did not differ (75.6% vs. 73.7%, P = 0.580). However, the prevalence of high TC (8.4% vs. 28.2%, P < 0.001) and high LDL (8.5% vs. 62.6%, P < 0.001) was lower in HIV-positive than HIV-negative subjects, and the prevalence of high TG (33.9% vs. 17.0%, P < 0.001) and low HDL (59.6% vs. 11.2%, P < 0.001) was higher in HIV-positive than HIV-negative subjects. Logistic analysis showed that HIV positivity was significantly associated with both an increased risk of high TG and low HDL and a decreased risk of high TC and high LDL. The mean levels of TC, of LDL and of HDL showed an increasing trend with increasing CD4 count in HIV-positive subjects. Multivariable logistic regression found that lower CD4 count was significantly associated with both an increased risk of high TG and low HDL and a decreased risk of high TC in HIV-positive subjects. Among antiretroviral-naive HIV-infected Chinese adults, there was a high prevalence of dyslipidemia characterized by

To explore the relationship between the polymorphisms and haplotypes in the CETP gene and dyslipidemia among Xinjiang Kazak and Uygur residents. A population status survey was performed from 2010 to 2011 in Kashgar Xinjiang Uygur and Kazak residents, stratified cluster sampling method was used to select Uygur, Kazak residents with abnormal blood lipid values (n=367 and 345, respectively) as the dyslipidemia groups, and to select residents with normal lipid values as control group from the same area (n=374 and 390, respectively). SNaPshot technology was applied to detect the DNA of CETP gene rs3764261, rs1800775, rs708272 and rs5882 loci in all selected residents, and linkage disequilibrium analysis and haplotype construction were performed. (1) In Uygur residents, the dyslipidemia risk of rs708272 CT (OR=0.64, 95%CI 0.46-0.91, P=0.01) and TT genotype (OR=0.60, 95%CI 0.40-0.91, P=0.02) was significantly lower than CC genotype. Dyslipidemia risk of rs3764261 GT (OR=0.55, 95%CI 0.40-0.74, P=0.00) and TT genotype (OR=0.47, 95%CI 0.28-0.78, P<0.01) was significantly lower than GG genetype. Dyslipidemia risk of the rs1800775 CC genotype was higher than AA genotype (OR=1.79, 95%CI 1.17-2.74, P=0.01). There was no statistical significance in CETP gene of the 4 genotype and allele frequency between the dyslipidemia and normal lipid groups in Kazak residents (all P>0.05). (2) In Uighur residents with dyslipidemia, HDL-C level was significantly higher in rs708272 TT genotype carriers than in CC and CT genotypes (all P<0.05) and in rs3764261 TT genotype carriers than in GG genotype carriers (P=0.008), while was significantly lower in rs1800775 CC genotype carriers with AA genotype carriers (P=0.008). (3) Linkage disequilibrium analysis showed that there was strong linkage disequilibrium between rs3764261 and rs708272 (D'=0.869, r(2)=0.869), rs1800775 and rs708272 (D'=0.845, r(2)=0.446) in Uighur residents, and there was strong linkage disequilibrium between rs3764261 and rs

Cardiovascular disease (CVD) remains the leading cause of morbidity and mortality for patients with type 2 diabetes, despite recent significant advances in management strategies to lessen CVD risk factors. A major cause is the atherogenic dyslipidemia, which consists of elevated plasma concentrations of both fasting and postprandial triglyceride-rich lipoproteins (TRLs), small dense low-density lipoprotein (LDL) and low high-density lipoprotein (HDL) cholesterol. The different components of diabetic dyslipidemia are not isolated abnormalities but closely linked to each other metabolically. The underlying disturbances are hepatic overproduction and delayed clearance of TRLs. Recent results have unequivocally shown that triglyceride-rich lipoproteins and their remnants are atherogenic. To develop novel strategies for the prevention and treatment of dyslipidaemia, it is essential to understand the pathophysiology of dyslipoproteinaemia in humans. Here, we review recent advances in our understanding of the pathophysiology of diabetic dyslipidemia. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

We developed a common feature pharmacophore model using known antiadipogenic compounds (CFPMA). We identified rohitukine, a reported chromone anticancer alkaloid as a potential hit through in silico mapping of the in-house natural product library on CFPMA. Studies were designed to assess the antiadipogenic potential of rohitukine. Rohitukine was isolated from Dysoxylum binacteriferum Hook. to ⬧95% purity. As predicted by CFPMA, rohitukine was indeed found to be an antiadipogenic molecule. Rohitukine inhibited lipid accumulation and adipogenic differentiation in a concentration- and exposure-time-dependent manner in 3T3-L1 and C3H10T1/2 cells. Rohitukine downregulated expression of PPARγ, CCAAT/enhancer binding protein α, adipocyte protein 2 (aP2), FAS, and glucose transporter 4. It also suppressed mRNA expression of LPL, sterol-regulatory element binding protein (SREBP) 1c, FAS, and aP2, the downstream targets of PPARγ. Rohitukine arrests cells in S phase during mitotic clonal expansion. Rohitukine was bioavailable, and 25.7% of orally administered compound reached systemic circulation. We evaluated the effect of rohitukine on dyslipidemia induced by high-fat diet in the hamster model. Rohitukine increased hepatic expression of liver X receptor α and decreased expression of SREBP-2 and associated targets. Rohitukine decreased hepatic and gonadal lipid accumulation and ameliorated dyslipidemia significantly. In summary, our strategy to identify a novel antiadipogenic molecule using CFPMA successfully resulted in identification of rohitukine, which confirmed antiadipogenic activity and also exhibited in vivo antidyslipidemic activity.

Dyslipidemia is one of the major risk factors for atherosclerosis and the main cause of death in the developing and developed countries. In this cohort study, the incidence of dyslipidemia and its components have been studied among individuals over 20 years old in Ahvaz, southwest of Iran. The Phase 1 of this study was conducted on the prevalence of Metabolic syndrome and its related factors by Diabetes Research Center in 2009. The target population included individuals over 20 years old who were selected using cluster sampling in Ahvaz health centers. In the second phase of the study, 5 years later in 2014, subjects were again recalled by health centers. Questionnaires, anthropometric indices and measurements were repeated similar to Phase 1. The blood sample was taken from everyone after 12h of fasting and then the factors (Chol, TG, HDL) were measured. The cumulative incidence of dyslipidemia obtained 60.7% (males 56.7% and females 64.8%). lipid profile {HDL, Triglycerides and Cholesterol had changes in their means(a significant reduction in the mean about 10, 22.25 and 13 units respectively) between baseline and 5 years later. Waist circumference here associated with incidence of high LDL and high chol, also sex and High LDL 'educational level and daily consumption of vegetables were associated with incidence of low HDL and dyslipidemia respectively. Age, educational level and daily intake of fruits and vegetables were effective variables on incidence of dyslipidemia. According to various studies, LDL and HDL levels in different regions of Iran, seems to be influenced by factors such as climate, nutrition and activity levels. Copyright © 2017 Diabetes India.

Our latest study reported the grim status of hypertension in rural China with the prevalence of hypertension reached 51.1%. However, we lack the latest data about the prevalence and epidemiological features of dyslipidemia among hypertensive residents in rural China. A cross-sectional survey was conducted from July 2012 to August 2013 through a cluster multistage sampling to a resident group of 4048 individuals (2152 men, 2896 women) with hypertension, age ≥ 35 years, in the rural Northeast China. Serum lipids level were proposed by National Cholesterol Education Program Adult Treatment Panel III. Of the hypertension residents without antihypertension treatment, 34.5% had borderline high total cholesterol, 19.2% had high total cholesterol, 11.4% had low high-density lipoprotein cholesterol and 37.4% had high non HDL-C. The population with borderline high, high, and very high low-density lipoprotein cholesterol was 20.9, 6.7 and 2.3%, respectively. In addition, 14.3% had borderline high triglycerides, 17.4% had high TG and 2.4% had very high TG. The awareness rate of dyslipidemia among the study population was 5.9%. After adjusting for independent variables, fasting plasma glucose, body mass index, Han nationality, current drinking and smoking, higher annual income and classification of blood pressure were risk factors for dyslipidemia while moderate physical activity was protective factor for dyslipidemia. On the contrary, gender and current drinking decrease the risk of HDL-C. The prevalence of dyslipidemia was dramatically high and dyslipidemia screening was in-need in all diagnosed hypertensive individuals.

Objective: The purpose of this study was to investigate the prevalence and risk factors of dyslipidemia in a rural population of Henan Province, China. Methods: A total of 20 194 participants aged ≥18 years were selected randomly by cluster sampling from two townships(towns)in Henan Province from July to August 2007 and July to August 2008. Investigations included questionnaires, anthropometric measurements, fasting plasma glucose, and lipid profile examination at baseline. A total of 16 155 participants were followed up from July to August 2013 and July to October 2014. Overall, 13 869 participants were included in the study, after excluding 2 286 participants with incomplete dyslipidemia follow-up data. Distributions of the characteristics of dyslipidemia were determined, and prevalence was standardized by age according to data of the 2010 Sixth National Population Census. Risk factors for dyslipidemia were analyzed using a logistic regression model after adjusting for sex, age, education level, marital status, and income status. Results: The prevalence of dyslipidemia was 53.72%(7 450/13 869)for residents aged ≥22 years living in rural areas of Henan Province(59.32%(3 069/5 174)for men and 50.39%(4 381/8 695)for women). The adjusted prevalence of dyslipidemia was 50.50%(59.27% for men and 45.53% for women). The prevalence of hypercholesterolemia, hypertriglyceridemia, low HDL-C, and high LDL-C was 4.34%(602/13 868), 20.42%(2 826/13 837), 42.75%(5 927/13 865), and 3.14%(420/13 375), respectively, and the adjusted prevalence was 2.44%, 18.84%, 41.42%, and 1.86%, respectively. Logistic regression analyses showed that alcohol consumption( OR =1.27, 95% CI : 1.05-1.53), family history of hyperlipidemia( OR =1.29, 95% CI : 1.17-1.43), overweight( OR =1.40, 95% CI : 1.22-1.61), obesity( OR = 1.65, 95% CI : 1.39- 1.96), abnormal waist circumference( OR =1.22, 95% CI : 1.04- 1.43), and abnormal waist-height ratio( OR =1.21, 95% CI : 1.01-1.45)were significant

Current preventive and treatment guidelines for type 2 diabetes have failed to decrease the incidence of comorbidities, such as dyslipidemia and ultimately heart disease. The goal of this review is to describe the physiological and metabolic lipid alterations that develop in patients with type 2 diabetes mellitus. Questions addressed include the differences in lipid and lipoprotein metabolism that characterize the dyslipidemia of insulin resistance and type 2 diabetes mellitus. We also examine the relevance of the new AHA/ADA treatment guidelines to dyslipidemic individuals. In this review, we provide an update on the pathophysiology of diabetic dyslipidemia, including the role of several apolipoproteins such as apoC-III. We also point to new studies and new agents for the treatment of individuals with type 2 diabetes mellitus who need lipid therapies. Type 2 diabetes mellitus causes cardiovascular disease via several pathways, including dyslipidemia characterized by increased plasma levels of apoB-lipoproteins and triglycerides, and low plasma concentrations of HDL cholesterol. Treatments to normalize the dyslipidemia and reduce the risk for cardiovascular events include the following: lifestyle and medication, particularly statins, and if necessary, ezetimibe, to significantly lower LDL cholesterol. Other treatments, more focused on triglycerides and HDL cholesterol, are less well supported by randomized clinical trials and should be used on an individual basis. Newer agents, particularly the PCSK9 inhibitors, show a great promise for even greater lowering of LDL cholesterol, but we await the results of ongoing clinical trials.

Almost 80% of strokes are ischaemic and stroke is the third most common cause of death in developed countries, . The treatment of stroke still limited, the best approach to reduce mortality and morbidity is primary prevention through modification of acquired risk factors. Hypertension and dyslipidemia are one of the major risk factor for stroke while homocysteine is a less well-documented risk factor. The purpose of this study was to know the correlation between homocysteine and dyslipidemia in ischaemic stroke patients with and without hypertension. This study is a cross sectional study; the sample were taken consecutively. All sample matched with inclusion and exclusion criteria, demography data and blood sample were taken. Demography data was analyzed using descriptive statistic, to analyze the relation, we used Chi-Square test. p value <0,05 was significant. Of the 100 patients, were divided into two groups, with hypertension, and without hypertension, hyperhomocysteinemia was found in 62 patients (59 patients had mild hyperhomocysteinemia, three patients had moderate hyperhomocysteinemia) and dyslipidemia was found in 60 patients. There is a significant relation between homocysteine and dyslipidemia in ischaemic stroke patients with hypertension, p value = 0,009. A significant correlation between homocysteine and dyslipidemia might be because both of them have an important role in the acceleration of the atherosclerotic formation by activation platelet and thrombus, but we still need further study to get more explanation about the relation.

In essential hypertension, the comorbidity of dyslipidemia is very common. In addition to hypertension, dyslipidemia is linked to cardiovascular disease, stroke and decline in renal function. Unlike other angiotensin receptor blockers, Losartan has been claimed to have unique pleiotropic property and thereby decreasing the risk of future cardiovascular complications. The present study was done to assess on the pleiotropic effect of losartan in newly diagnosed hypertensive patients with dyslipidemia. Fifty four hypertensive patients with dyslipidemia who fulfilled the eligible criteria and were willing to give informed consent were included in the study after getting Institutional Ethical Committee (IEC) approval. All the study participants were given tab. Losartan 50mg once daily for four weeks. At the end of 1st, 2nd, 3rd and 4th week, blood pressure control and compliance were monitored. At the end of 4th week all the baseline laboratory parameters like renal function test, liver function test, lipid prolife and random blood sugar were performed. The EQ-5D questionnaires were completed at two points during the study: at the patient's initial visit before enrollment in the study and after 4 weeks of Losartan therapy. Appropriate statistical methods were used to analyse the results.The primary endpoint was reduction in blood pressure and improvement in lipid profile and improvement in quality of life score from baseline after 4 weeks of losartan therapy. Four patients were withdrawn due to non-compliance and totally 50 patients completed the study. The mean systolic blood pressure was reduced from 154.54 mm Hg to 138.16 mm Hg with p<0.0001 and the mean diastolic blood pressure was reduced from 91.56 mm Hg to 82.44 mm Hg with p<0.0001. There was a significant reduction in the mean total cholesterol from 189.52 to 180.46 mg/dl, mean LDL from 110.50 to 101.32 mg/dl and mean triglygeride from 135.68 to 127.70 mg/dl with p<0.0001.

To evaluate vitamin D status in middle-aged subjects in Beijing and explore the correlation between serum 25-hydroxyvitamin D[25(OH)D] levels and dyslipidemia. A total of 448 individuals over 40 years old were enrolled in the cross-sectional survey. The general information, blood biochemical and lipid profiles and serum 25(OH)D levels were collected. The subjects were either divided into two groups (the dyslipidemia group and the non-dyslipidemia group) based on the lipid levels, or four groups according to quartiles of 25(OH)D levels. The association between 25(OH)D levels and dyslipidemia risk was analyzed by a logistic regression analysis. A total of 234 cases were in dyslipidemia group, which accounted for 52.23% of the subjects. The serum 25(OH)D levels were significantly lower in the dyslipidemia group than in the non-dyslipidemia group both in men and in women (all P<0.05). The median serum 25(OH)D level in the total subjects was 15.7 (12.2, 20.1)μg/L with 91.1% subjects of serum 25(OH)D level<30 μg/L. The proportion of subjects with dyslipidemia (high TC, high TG, high LDL-C, or low HDL-C) increased with the decrease of 25(OH)D level quartiles (P<0.05). After adjustment of confounding factors, the logistic regression analysis showed that subjects in the lowest 25(OH) D quartile group had 143% higher risks for dyslipidemia than those in the highest quartile group. These findings indicate that 25(OH)D insufficiency is highly prevalent among middle-aged individuals and it may be associated with the risk of dyslipidemia.

Dyslipidemia is an important independent modifiable risk factor for cardiovascular disease. The aim of this study was to explore the current prevalence, awareness, treatment and control of dyslipidemia and its associated influence factors in northeast China. In this population-based cross-sectional study, we adopted a multi-stage, stratified sampling method to obtain a representative sample of 4052 permanent residents aged 40 years and over from different urban and rural regions in Dehui City of Jilin Province. All subjects completed a questionnaire and were examined for risk factors. Continuous data were presented as means ± standard deviations (SD) and compared using the Student's t-test. Categorical variables were presented as proportions and compared using the Rao-Scott-χ 2 test in different subgroups. The associated influence factors for the prevalence, awareness, treatment and control of dyslipidemia were evaluated through multivariate logistic regression. The prevalence of dyslipidemia was 62.1% overall, with 33.5, 43.9, 0.6, and 8.8% for high total cholesterol, triglyceride, low-density lipoprotein cholesterol, and low high-density lipoprotein cholesterol, respectively. Among those with dyslipidemia, the proportion of subjects who were aware, treated, and controlled was 14.4, 33.9, and 19.9%, respectively. Overweight or obesity (OR = 2.156; 95% CI: 1.863, 2.533), hypertension (OR = 1.643; 95% CI: 1.425, 1.893), or diabetes mellitus (OR = 2.173; 95% CI: 1.661, 2.844) increased the prevalence of dyslipidemia, also these participants were more likely to be aware of their condition, however, this did not increase the likelihood of treatment and control. Living in urban areas and higher education level also increased the awareness of dyslipidemia. Personal history of coronary heart disease was the strongest influence factors associated with better awareness, treatment and control of dyslipidemia. Overweight or obesity (OR = 0.404; 95% CI

Atherogenic dyslipidemia is frequently observed in persons with a greater amount of visceral adipose tissue (VAT). However, it is still uncertain whether VAT is independently associated with the future development of atherogenic dyslipidemia. The aim of this study was to determine whether baseline and changes in VAT and subcutaneous adipose tissue (SAT) are associated with future development of atherogenic dyslipidemia independent of baseline lipid levels and standard anthropometric indices. Community-based prospective cohort study with 5 years of follow-up. A total of 452 Japanese Americans (240 men, 212 women), aged 34-75 years were assessed at baseline and after 5 years of follow-up. Abdominal fat areas were measured by computed tomography. Atherogenic dyslipidemia was defined as one or more abnormalities in high-density lipoprotein (HDL) cholesterol, triglycerides, or non-HDL cholesterol levels. Baseline VAT and change in VAT over 5 years were independently associated with log-transformed HDL cholesterol, log-transformed triglyceride, and non-HDL cholesterol after 5 years (standardized β = -0.126, 0.277, and 0.066 for baseline VAT, respectively, and -0.095, 0.223, and 0.090 for change in VAT, respectively). However, baseline and change in SAT were not associated with any future atherogenic lipid level. In multivariate logistic regression analysis, incremental change in VAT (odds ratio [95% confidence interval], 1.73 [1.20-2.48]; P = .003), triglycerides (4.01 [1.72-9.33]; P = .001), HDL cholesterol (0.32 [0.18-0.58]; P < .001), and non-HDL cholesterol (7.58 [4.43-12.95]; P < .001) were significantly associated with the future development of atherogenic dyslipidemia independent of age, sex, diastolic blood pressure, homeostasis model assessment insulin resistance, body mass index (BMI), change in BMI, SAT, and baseline atherogenic lipid levels. Baseline and change in VAT were independent predictors for future development of atherogenic dyslipidemia. However

Treatment of dyslipidemia is a major burden for public health. Thyroid hormone regulates lipid metabolism by binding the thyroid hormone receptor (TR), but the use of thyroid hormone to treat dyslipidemia is not indicated due to its deleterious effects on heart, bone, and muscle. Thyroid hormone analogs have been conceived to selectively activate TR in the liver, thus reducing potential side-effects. The authors searched the PubMed database to review TR and the action of thyromimetics in vitro and in animal models. Then, all double-blind, placebo controlled trials that analyzed the use of thyroid hormone analog for the treatment of dyslipidemia in humans were included. Finally, the ongoing research on the use of TR agonists was searched, searching the US National Institutes of Health Registry and the WHO International Clinical Trial Registry Platform (ICTRP). Thyromimetics were tested in humans for the treatment of dyslipidemia, as a single therapeutic agent or as an add-on therapy to the traditional lipid-lowering drugs. In most trials, thyromimetics lowered total cholesterol, low-density lipoprotein cholesterol, and triglycerides, but their use has been associated with adverse side-effects, both in pre-clinical studies and in humans. The use of thyromimetics for the treatment of dyslipidemia is not presently recommended. Future possible clinical applications might include their use to promote weight reduction. Thyromimetics might also represent an interesting alternative, both for the treatment of non-alcoholic steatohepatitis, and type 2 diabetes due to their positive effects on insulin sensitivity. Finally, additional experimental and clinical studies are needed for a better comprehension of the effect(s) of a long-term therapy.

Previous studies reporting that statin increases coronary artery calcium (CAC) were conducted exclusively on patients with statin as a prevention, regardless of the presence or absence of dyslipidemia. The impact of sex on CAC has not been fully evaluated. We aimed to determine the association of dyslipidemia and sex with CAC using 320-row multi-detector computed tomography (MDCT).Of the 356 consecutive patients who underwent coronary MDCT, 251 patients were enrolled, after excluding those with prior stenting and/or coronary bypass grafting or images showing motion artifacts. The primary outcome measures were the percent calcium volume (PCV) and percent atheroma volume (PAV) per coronary vessel.Multivariable analyses indicated that PCV was significantly higher in dyslipidemia patients without statins than in the subjects without dyslipidemia [partial regression coefficient (PRC): 2.59, 95% confidence interval (CI): 0.83 to 4.34, P = 0.004]. In contrast, PCV was similar in dyslipidemia patients taking statins and those without dyslipidemia (PRC: -1.09, 95% CI: -2.82 to 0.65, P = 0.22). There was no significant difference in PCV between men and women, although women exhibited a significantly lower PAV (PRC: -2.87, 95% CI: -4.54 to -1.20, P = 0.001).In low-risk patients, these results could be translated into hypotheses, which should be tested in future prospective studies. Furthermore, there was no significant difference in CAC between men and women, but women had lower PAV than men.

The objective of this study was to determine the proportion of Greek patients referred to outpatient clinics for dyslipidemia who achieved the low-density lipoprotein cholesterol (LDL-C) goal defined by the National Cholesterol Education Program Adult Treatment Panel III (NCEP-ATP III) guidelines, using lifestyle changes, lipid-lowering drug treatment (LLDT), or both. Adult patients with dyslipidemia, who had been receiving a hypolipidemic diet and/or LLDT for at least 3 months were assessed in a multicenter study performed at 66 sites across Greece. Patients were followed up for an additional 3-month treatment period. Lipid levels were recorded at baseline and at the end of the study. The primary endpoint was the proportion of patients achieving their individual LDL-C target at the end of the study, according to their coronary heart disease (CHD) risk status or its equivalents, as defined by the NCEP-ATP III guidelines. Multivariate logistic models were used to identify determinants of undertreatment. The study included 2,660 adults (20-75 years) from 7 regions of Greece. Of the evaluable sample (n = 2,211; men 51%; mean age 62 +/-9 years) 81% were receiving LLDT (96% with statins and 3% with fibrates), 44% had a history of CHD, 61% arterial hypertension, 36% diabetes, and 26% a family history of premature CHD. Overall, 6% were at low CHD risk, 30% at medium CHD risk, and 63% at high CHD risk. At the end of the study, 26% of all patients and 30% of those receiving LLDT achieved the NCEP-specified LDL-C target levels. The percentage of patients at LDL-C goal according to CHD risk status was: low risk 67% (95% CI = 59-75), medium risk 29% (95% CI = 26-33), and high risk 20% (95% CI = 18-22). Statins proved to be more effective than fibrates (p <0.0001). Atorvastatin-treated subjects (n = 1,222, mean dose 19 mg/day) attained the LDL-C target (31% of the cases) at a higher rate than those receiving other LLDT (n = 574, 26% at target, p <0.01) or not receiving drug

Evaluation and Management of Dyslipidemia in Patients with HIV Infection

OBJECTIVE Persons with HIV infection develop metabolic abnormalities related to their antiretroviral therapy and HIV infection itself. The objective of this study was to summarize the emerging evidence for the incidence, etiology, health risks, and treatment of dyslipidemias in HIV disease. DESIGN Systematic review of original research with quantitative synthesis. MAIN RESULTS Dyslipidemia is common in persons with HIV infection on highly active antiretroviral therapy (HAART), but methodologic differences between studies preclude precise estimates of prevalence and incidence. The typical pattern includes elevated total cholesterol, low-density lipoprotein cholesterol, and triglycerides, which may be markedly elevated. The dyslipidemia may be associated with lipodystrophy, insulin resistance, and, rarely, frank diabetes mellitus. Exposure to protease inhibitors (PIs) is associated with this entire range of metabolic abnormalities. PI-naïve patients on nucleoside reverse transcriptase inhibitors (NRTIs) may develop lipodystrophy, insulin resistance, hypercholesterolemia, and possibly modest elevations in triglycerides but not severe hypertriglyceridemia, which appears to be linked to PIs alone. Most studies have not found an association between CD4 lymphocyte count or HIV viral load and lipid abnormalities. The pathogenesis is incompletely understood and appears to be multifactorial. There are insufficient data to definitively support an increased coronary heart disease risk in patients with HIV-related dyslipidemia. However, some of the same metabolic abnormalities remain firmly established risk factors in other populations. Patients on HAART with severe hypertriglyceridemia may develop pancreatitis or other manifestations of the chylomicronemia syndrome. Some of the metabolic derangements (particularly hypertriglyceridemia) may improve upon replacing a PI with a non-nucleoside reverse transcriptase inhibitor. The limited experience suggests that fibrates

Update on the clinical utility of fenofibrate in mixed dyslipidemias: mechanisms of action and rational prescribing

PubMed Central

Farnier, Michel

2008-01-01

Mixed dyslipidemia is a common lipid disorder characterized by the presence of an atherogenic lipoprotein phenotype due to abnormalities in various atherogenic and anti-atherogenic lipoproteins. Despite the link between the decrease of LDL-cholesterol by statin treatment and the prevention of cardiovascular disease, a high residual risk is observed in statin trials. This residual risk is partly explained by lipoprotein abnormalities other than LDL. Fenofibrate exerts a favorable effect on the atherogenic lipid profile of mixed dyslipidemia and can effectively reduce cardiovascular disease in patients with mixed dyslipidemia. Fenofibrate may offer important treatment alternatives as a second-line therapy in several circumstances: in combination with a statin for patients with mixed dyslipidemias not at goals on statin mono-therapy; in monotherapy for patients intolerant or with contraindication to statin therapy; and in combination with other drugs (ezetimibe, colesevelam) for patients with mixed dyslipidemias, known intolerance, or contraindication to statin and not at goals on fenofibrate monotherapy. However, the role of fenofibrate-statin therapy and of other therapies involving fenofibrate in cardiovascular risk reduction strategies remains to be established. PMID:19183747

The association between atherogenic dyslipidemia and stroke recurrence remains unclear, and may be influenced by different subtypes of ischemic stroke. We aimed to investigate whether atherogenic dyslipidemia contributed to stroke recurrence in ischemic stroke patients and in those with certain subtypes of ischemic stroke. We conducted a prospective hospital-based study enrolling patients with acute ischemic stroke. Atherogenic dyslipidemia was defined as high-density lipoprotein cholesterol <40 mg/dl and triglycerides ≥200 mg/dl. Ischemic stroke subtypes were classified according to the Trial of Org 10172 in Acute Stroke Treatment criteria. The patients were followed up at 3, 6, 12 and 24 months after stroke onset. The association between atherogenic dyslipidemia and stroke recurrence was analyzed by using multivariable Cox regression model. In the 510 ischemic stroke patients, 64 patients (12·5%) had atherogenic dyslipidemia, and 66 patients (12·9%) experienced stroke recurrence events within 24 months. Kaplan-Meier analysis revealed that stroke recurrence rate was significantly higher in patients with atherogenic dyslipidemia than those without in all the stroke patients (20·3% vs. 11·9%; P = 0·048), and more evident in those of large-artery atherosclerosis subtype (31·0% vs. 14·1%; P = 0·014), but not in the other subtypes. Multivariable Cox regression analysis revealed that atherogenic dyslipidemia was associated with higher stroke recurrence risk among stroke patients of large-artery atherosclerosis subtype (hazard ratio, 2·79; 95% confidence interval, 1·24-6·28), but not significant in all the stroke patients (hazard ratio, 1·69; 95% confidence interval, 0·85-3·37). Atherogenic dyslipidemia is associated with higher risk of stroke recurrence in ischemic stroke patients. Such association might be more pronounced in large-artery atherosclerosis subtype and needs further investigation to establish such relationship. © 2015 World

Dyslipidemia is a very common metabolic abnormality in women with polycystic ovary syndrome (PCOS). Insulin resistance is a key pathophysiology of PCOS, thus dyslipidemia in women with PCOS may be consistent with those found in an insulin resistant state. In recent meta-analysis, triglycerides and low-density lipoprotein (LDL) cholesterol levels were 26 mg/dL and 12 mg/dL higher, and high-density lipoprotein cholesterol concentration was 6 mg/dL lower in women with PCOS than those of controls. Alterations in LDL quality also have been reported in women with PCOS: women with PCOS have an increased proportion of atherogenic small dense LDL or decreased mean LDL particle size. However, in a recent Korean study, non-obese Korean women with PCOS had no significant quantitative or qualitative changes in LDL cholesterol profile. Lipoprotein (a) has been identified as an independent risk factor for coronary heart disease, and its elevation in PCOS patients has been consistently reported in diverse studies including non-obese Korean population. Some studies have investigated apolipoprotein (Apo) A-I and ApoC-I levels in women with PCOS and levels of ApoA-I, which has cardio-protective effects, were significantly lower in women with PCOS than those of controls. ApoC-I is known to increase the postprandial serum lipid level that is common in coronary artery disease patients, and one study reported that such an elevation may be the earliest variation of lipid abnormality in women with PCOS. In conclusion, women with PCOS should receive a complete lipid test, and lifestyle modification, including diet and exercise, is the first line therapy for all women with PCOS and is particularly important for those with dyslipidemia.

Improvement of dyslipidemia is an important benefit of bariatric surgery. The benefits of laparoscopic sleeve gastrectomy (LSG) among dyslipidemia are still a matter of debate. We conducted a retrospective descriptive study between 2010 and 2013. Obese patients undergoing LSG, with recorded dyslipidemia at admission and a follow-up for at least 1 year, were included for analysis. Demographic characteristics, medication in use, and a complete lipid profile were collected before surgery. After surgery, weight was controlled at 1, 3, 6, and 12 months. Lipid profile was re-evaluated 1 year after surgery. Patients were divided according to weight loss into two groups: (A) adequate weight loss and (B) inadequate weight loss. Lipid profile evolution was then compared between groups. One hundred seven patients met the inclusion criteria. Pre-op mean BMI was 45.13 ± 7.5 kg/m 2 . One year after LSG, mean BMI was 30.6 ± 7.1 kg/m 2 with a change in BMI of 11.5 ± 6.6 kg/m 2 , a %TWL of 26.9 ± 13.5%, and a %EWL of 60.3 ± 36.6%. Hypercholesterolemia and hypertriglyceridemia remission was achieved in 45 and 86% of the patients and improved in another 19 and 4% respectively. Seventy-four percent improved HDL levels. LDL levels improved in 39% and remitted in 37%. Medication was discontinued in 43.7%. HDL increase and LDL, TG, and non-HDL-C decrease were significantly greater in group A. LSG produces an improvement in lipid profile, with a significant increase in HDL and a decrease in LDL, triglycerides, and non-HDL-C.

To study the prevalence of dyslipidemia and metabolic syndrome risk factors in overweight/ obese children and adolescents. The study included 139 healthy white Argentinean children/adolescents (aged 8-14 years) who were overweight (n = 30) or obese (n = 109), based on BMI z score according to WHO, 2007. Children were referred to the Nutrition Clinic, San Martin University Hospital, Buenos Aires, Argentina for evaluation and treatment. Dyslipidemia was considered when one or more serum lipids (mg/dL) were out of range: total cholesterol ≥ 200, high-density lipoprotein (HDL-C) ≤ 40, triglycerides (TG) > 110, low-density lipoprotein (LDL-C) > 130 or non-HDL-C > 145 and fasting blood glucose (FBG) > 110. Additional metabolic syndrome risk factors included: increased waist circumference (WC, ≥ 90th percentile) and high blood pressure (> 90th percentile). A history of low birth weight (< 2.5 kg) and a family history of: dyslipidemia (FHDL), premature acute myocardial infarction (FHPAMI) and/or type 2 diabetes mellitus (FHT2DM) were also assessed. The prevalence of dyslipidemia among overweight and obese children was 50.4% and its pattern was: hypertriglyceridemia 31.9%, low HDL-C 29.7%, high non-HDL-C 15.8%, hypercholesterolemia 11.9%, and elevated LDL-C 10.7%. The dyslipidemia was more often detected among those with increased WC (55.4%), FHDL (51.1%), and FHT2DM (48%); prevalence was lower in those with FHPAMI (18.7%) and low birth weight (4.3%). Most children presented a variety of metabolic syndrome risk factors; only 25.8% did not have any such alterations identified. BMI z score showed a positive association with TG and negative with HDL-C. Overweight and obesity increased the odds ratios of metabolic syndrome risk factors, hypertriglyceridemia and low HDL-C. Overweight/obese children were prone to have dyslipidemia and metabolic syndrome. Excess body weight is an important harbinger of health that requires the assessment of multiple parameters to discern

Dyslipidemia is one of the major complications of obesity; vitamin D deficiency and insulin resistance are attending metabolic complications in dyslipidemic obese children. Objective. To determine if vitamin D deficiency and insulin resistance are risk factors for dyslipidemia in obese children. This study was conducted in the Department of Pediatrics at Bagcilar Training and Research Hospital in Istanbul, Turkey between 2014 and 2015. Obese patients whose age range was 8-14 were included in the study. The serum triglyceride, total cholesterol, low-density lipoprotein cholesterol, highdensity lipoprotein cholesterol, fasting glucose, insulin, alanine aminotransferase, vitamin D levels were measured; a liver ultrasonography was performed. Homeostatic model assessment (HOMA-IR), was used to calculate insulin resistance. 108 obese children were included; 39 (36.11%) had dyslipidemia. The average fasting blood glucose (88.74 ± 7.58 vs. 95.31 ± 6.82; p= 0.0001), insulin level (14.71 ± 12.44 vs. 24.39 ± 15.02; p= 0.0001) and alanine aminotransferase level (23.45 ± 11.18 vs. 30.4 ± 18.95; p= 0.018) were significantly higher in the children with dyslipidemia. In the dyslipidemic obese children, the average hepatosteatosis rate and HOMA-IR level were higher; 28 (71.9%) had hepatosteatosis, 37 (94.87%) had insulin resistance; the vitamin D levels were <20 ng/ml in 69.3%. Vitamin D deficiency was significantly more common (p= 0.033). The multivariate regression analysis confirmed that the increase in the HOMA-IR level (p= 0.015) and the low vitamin D level (p= 0.04) were important risk factors for dyslipidemia. Obese children in our region exhibit low vitamin D and increased HOMA-IR levels, which are efficient risk factors of dyslipidemia.

Introduction. Dyslipidemia like other chronic degenerative diseases is pandemic in Latin America and around the world. A lot of patients asking for body contouring surgery can be sick without knowing it. Objective. Observe the lipid profile of patients with dyslipidemia, before and three months after an abdominoplasty. Methods. Patients candidate to an abdominoplasty without morbid obesity were followed before and three months after the surgery. We compared the lipid profile, glucose, insulin, and HOMA (cardiovascular risk marker) before and three months after the surgery. We used Student's t test to compare the results. A P value less than 0.05 was considered as significant. Results. Twenty-six patients were observed before and after the surgery. At the third month, we found only statistical differences in LDL and triglyceride values (P 0.04 and P 0.03). The rest of metabolic values did not reach statistical significance. Conclusion. In this group of patients with dyslipidemia, at the third month, only LDL and triglyceride values reached statistical significances. There is no significant change in glucose, insulin, HOMA, cholesterol, VLDL, or HDL. PMID:23956856

Dyslipidemia, Hypertension and Diabetes Metaflammation. A Unique Mechanism for 3 Risk Factors.

PubMed

Morales-Villegas, E

2014-07-01

The main current threat to the human race is the correlation and synergy between two determining triumvirates of atherosclerosis, cardiovascular disease and death. The first triumvirate is constituted by obesity, metaflammation and insulin resistance; the second triumvirate is constituted by atherogenic dyslipidemia, hypertension and type 2 diabetes mellitus. The etiopathogenic driving force for both triumvirates is the global epidemic of obesity. Metaflammation and insulin resistance are associated with obesity; in turn, insulin resistance determines a high risk for the development of atherogenic dyslipidemia, hypertension and type 2 diabetes mellitus, the three of them being factors responsible for vascular endothelial injury and substrates involved in the genesis of atherosclerosis, cardiovascular disease and death. The present chapter will address both triumvirates. Firstly, the current concepts of obesity, metaflammation and insulin resistance will be reviewed; emphasizing the second (metaflammation) for being a concept that has revolutionized and integrated our understanding of the harmful effects of obesity. Secondly, the impact of insulin resistance in the regulation of intermediary metabolism and endothelial function will be addressed; this will facilitate the understanding of the inextricable link between atherogenic dyslipidemia, hypertension and type 2 diabetes mellitus. Thus, this chapter aims to present to the clinician the best knowledge to link epidemics of obesity and cardiovascular death, through the sequence of metaflammation, insulin resistance and cardiovascular risk factors (mixed dyslipidemia, hypertension and type 2 diabetes mellitus).

The aim of this study was to assess the levels of serum lipid and awareness, treatment, and control of dyslipidemia in type 2 diabetes mellitus (T2DM) patients from top-ranked endocrinology clinics in large cities of China. A cross-sectional study in a representative sample of 4807 Chinese adults 40 to 75 years of age was conducted during 2010 to 2011 at 20 endocrinology clinics in top-ranked hospitals covering most of the major cities of China. Serum lipid levels were measured, and treatment of dyslipidemia was recorded and assessed. In the present study, the prevalence of dyslipidemia was 67.1% in T2DM subjects. Among those with dyslipidemia, the proportion of awareness and treatment was 68.7% and 55.9%. Among participants with lipid-lowering therapy, 686 subjects achieved the low-density lipoprotein cholesterol (LDL-C) control less than 2.60 mmol/L, with the rate being 39.4%. In those patients with previous cardiovascular disease, the percentage of participants who achieved LDL-C goal (1.80 mmol/L) was 15.3%. The prevalence of dyslipidemia is high, and the awareness, treatment, and control of dyslipidemia are relatively low in Chinese T2DM patients. This calls for the awareness and intervention of dyslipidemia in these patients. Copyright © 2016 National Lipid Association. Published by Elsevier Inc. All rights reserved.

To understand the proportion of dyslipidemia in systemic lupus erythematosus (SLE) patients and the influencing factors of dyslipidemia. AN observational, cross-sectional study was conducted on new and longstanding SLE patients who had been diagnosed based on ARA criteria 1982 with 1997 revision. They had been hospitalized and treated at Department of Internal Medicine, Cipto Mangunkusumo National Central General Hospital and the other private Hospitals in Jakarta, i.e. Kramat Hospital in July - November 2003. The sample was selected by non probability sampling method with consecutive sampling technique. Every participant underwent history taking, physical and laboratory examination. There were 77 patients satisfying the inclusion criteria. The proportion of dyslipidemia in this study was 75.3%. By confidence interval of 95%, the dyslipidemia in SLE patient was 65.3% - 84.6%. The distribution of lipid profile in sample population were 43% with total cholesterol > or = 200 mg/dL, 26% with HDL cholesterol level < 40 mg/dL, 26.4% with LDL cholesterol level > or = 130 mg/dl and 44.2% with triglycerides serum level > or = 150 mg/dL. The characteristics of influencing factors in dyslipidemia prevalence for sample population consisted of 24.7% with renal involvement, 53.2% with > or = 3 years illness periods, 26% had received > or = 30 mg/day prednisone, 94.8% had not received chloroquines, and 58.4% had illness activity of Mex-SLEDAI > or = 2. By bivariate analysis, we found that illness period < 3 years tends to affect dyslipidemia with OR value of 12.04 (CI 95%, 2.54-57.05, p = 0.001). After conducting multivariate analysis by backward methods, it appears that only one significant influencing factor of dyslipidemia prevalence in SLE patient i.e. Illness period od < 3 years with OR value 12.04 (CI 95% 2.54 - 57.05, p = 0.001). Illness period of 3 years is represent a significant correlative factor for dyslipedemia prevalence. Prednisone > or = 30 mg/dL is the

Endogenous nitric oxide (NO) is beneficial for inhibiting Rho-associated kinase 2 (ROCK2) expression. However, the effect of exogenous NO on ROCK2 expression is less investigated. Rabbits with dyslipidemia were produced and randomly assigned into untreated, atorvastatin, nitroglycerin and combined groups (n=10 in each group). Medication therapy was lasted for 2 weeks. Parameters of interest including lipid profiles, liver enzyme, C-reactive protein (CRP), malondialdehyde (MDA), NO level and ROCK2 level were assessed at baseline, 2 weeks of dyslipidemia establishment and 2 weeks of medication treatment. No significant difference in parameters was found between groups at baseline. With 2 weeks of dyslipidemia establishment, as compared to baseline, serum levels of lipid profiles, CRP and MDA were profoundly elevated. In addition, reduced NO generation and enhanced ROCK2 expression were also observed. With 2 weeks of medication therapy, lipid profiles, systemic inflammation (reflected as serum CRP level) and oxidation (reflected as serum MDA level) were improved in the atorvastatin and combined groups but not in the nitroglycerin group (P<0.05). Furthermore, increased NO production in accompany with reduced ROCK2 expression were observed in both the atorvastatin and nitroglycerin groups, and these benefits were further enhanced by combined therapy (P<0.05). No liver enzymes elevation was observed after 2 weeks of medication therapy. Nitroglycerin-derived exogenous NO could effectively inhibit ROCK2 expression in rabbits with dyslipidemia which is independent of lipid-modification, and these efficacies could be enhanced by statins therapy. © Georg Thieme Verlag KG Stuttgart · New York.

Iodine is an essential component of the thyroid hormone which plays crucial roles in healthy thyroid function and lipid metabolism. However, the association between iodine status and dyslipidemia has not been well established at a population level. We aimed to test the hypothesis that the odds of dyslipidemia including elevated total cholesterol, triglycerides, low-density lipoprotein (LDL) cholesterol and apolipoprotein B, and lowered high-density lipoprotein (HDL) cholesterol and HDL/LDL ratio are associated with urinary iodine concentration (UIC) in a population perspective. Data of 2495 US adults (≥20 years) in the National Health and Nutrition Examination Survey 2007-2012 were used in this study. Two subgroups (i.e., UIC below vs. above the 10th percentile) were compared of dyslipidemia as defined based on NCEP ATP III guidelines. The differences between the groups were tested statistically by chi-square test, simple linear regressions, and multiple logistic regressions. Serum lipid concentrations differed significantly between two iodine status groups when sociodemographic and lifestyle covariates were controlled (all, p < 0.05). Those with the lowest decile of UIC were more likely to be at risk for elevated total cholesterol (>200 mg/dL) (adjusted odds ratio (AOR) = 1.51, 95% confidence interval (CI): 1.03-2.23) and elevated LDL cholesterol (>130 mg/dL) (AOR = 1.58, 95% CI: 1.11-2.23) and lowered HDL/LDL ratio (<0.4) (AOR = 1.66, 95% CI: 1.18-2.33), compared to those with UIC above the 10th percentile. In US adults, low UIC was associated with increased odds for dyslipidemia. Findings of the present cross-sectional study with spot urine samples highlight the significant association between UIC and serum lipids at population level, but do not substantiate a causal relationship. Further investigations are warranted to elucidate the causal relationship among iodine intakes, iodine status, and serum lipid profiles.

Elevated free thyroxine (FT4) levels may play a protective role in development of dyslipidemia. However, few prospective studies have been performed to definite the effects of thyroid hormones on the improvement of dyslipidemia and its components. Thus, this study aims to clarify the association between thyroid hormones within normal range and reversal of dyslipidemia in the absence of intervention.A prospective analysis including 134 adult males was performed between 2010 and 2014. Anthropometric parameters, thyroid function, and lipid profile were measured at baseline and during follow-up. Logistic regression and receiver operating characteristic (ROC) analysis were conducted to identify the variables in forecasting the reversal of dyslipidemia and its components.During 4.5-year follow-up, 36.6% (49/134) patients resolved their dyslipidemia status without drug intervention. Compared with the continuous dyslipidemia group, subjects in reversal group had elevated FT4 and high-density lipoprotein cholesterol (HDL-C) levels, as well as decreased total cholesterol (TC), triglycerides (TG), and low-density lipoprotein cholesterol (LDL-C) levels at baseline. Furthermore, baseline FT4 is negatively associated with the change percentages of TG (r = -0.286, P = .001), while positively associated with HDL-C (r = 0.227, P = .008). However, no correlation of lipid profile change percentages with FT3 and TSH were observed. Furthermore, the improving effects of baseline FT4 on dyslipidemia, high TG, and low HDL-C status were still observed after multivariable adjustment. In ROC analysis, areas under curve (AUCs) for FT4 in predicting the reversal of dyslipidemia, high TG, and low HDL-C were 0.666, 0.643, and 0.702, respectively (P = .001 for dyslipidemia, .018 for high TG, and .001 for low HDL-C).Higher FT4 value within normal range may ameliorate the dyslipidemia, especially high TG and low HDL-C status, in males without drug intervention. This suggests

To explore the awareness, treatment and control rates of dyslipidemia among Chinese adults aged over 18 in 2010, and to analyze the prevalent features. 97 409 subjects aged over 18 were recruited from 162 monitoring sites around 31 provinces in China mainland in 2010, applying multi-stage stratified cluster random sampling method. Information about subjects' history of dyslipidemia, treatment and control were collected by face-to-face interview; and each subject's fasting venous blood was drawn in the morning before having food, to test total cholesterol (TC), triglyceride (TG), high density lipoprotein-cholesterol (HDL-C) and low density lipoprotein-cholesterol (LDL-C). In total, 51 818 cases of dyslipidemia ever or now, including 2235 subjects who once suffered from dyslipidemia but had their blood lipid controlled to normal, were screened out. And the awareness, treatment and control rates were calculated by complex weighting. The awareness rate of dyslipidemia among Chinese adults was 10.93%, while the stratified rates were 6.00%, 16.75% and 18.74% in the groups of subjects aged 18 - 44, 45 - 59 and over 60 years old, respectively (χ² = 1293.02, P < 0.01); 10.32% and 11.71% among males and females, respectively (χ² = 18.67, P < 0.01); 16.59% and 8.17% in groups from urban and rural areas, respectively (χ² = 618.38, P < 0.01); and 12.22%, 11.75% and 8.26% in groups from eastern, central and western China, respectively (χ² = 117.04, P < 0.01). The treatment rate of dyslipidemia was 6.84% among Chinese adults, while the stratified rates were 3.55%, 10.73% and 12.05% in the groups of subjects aged 18 - 44, 45 - 59 and over 60 years old, respectively (χ² = 858.72, P < 0.01); 6.37% and 7.43% among males and females, respectively (χ² = 16.69, P < 0.01); 10.17% and 5.21% in groups from urban and rural areas, respectively (χ² = 327.51, P < 0.01); and 7.33%, 7.52% and 5.41% in groups from eastern, central and western China, respectively (χ² = 50.71, P < 0

Cardiovascular disease (CVD) is the leading cause of death and one of the most important causes of morbidity in Western societies. Dyslipidemia is an important risk factor for CVD and effective treatment significantly reduces cardiovascular risk. To evaluate the prevalence and type of persistent lipid abnormalities in patients treated with statins. The Dyslipidemia International Study (DYSIS) was a multicenter, epidemiologic cross-sectional study conducted in 12 European countries and Canada. Patients > or = 45 years old, treated with statins for at least three months during the enrolment period from April 2008 to February 2009, were sequentially enrolled. This study presents the results for the Portuguese population. In Portugal, 916 patients were recruited in 125 centers; mean age was 64.1 +/- 9.9 years and 47.1% were women. Most patients (66.7%) presented high cardiovascular risk. The most frequently used statin was simvastatin (55.9%; dose 21.3 +/- 6.2 mg/day) and only 15.3% of the patients were simultaneously taking other lipid-lowering agents. In most patients, LDL (62.9%; n = 883) and total cholesterol (68%; n = 883) were not at the target levels recommended by the European Society of Cardiology (ESC). It was also found that 22% of patients presented lower HDL values than those recommended and that 39% presented high triglyceride levels. LDL outside the target range was the most common abnormality, both when assessed separately and when combined with low HDL and high triglycerides. The number of patients with lipid abnormalities was very significant, especially for LDL, considering that all were under statin therapy.

It is well known that hyperlipidemia is often present in patient with impaired glucose tolerance, obesity and/or hypertension. All of these are risk factors for coronary artery disease (CAD). The coexistence of these risk factors markedly increase the likelihood of CAD. Recently, it has been reported that the impaired glucose tolerance and insulin resistence are associated with the increased proinsulin, which is linked to the risk of CAD. We review that the impaired glucose tolerance is an important factor causing dyslipidemia. The characteristic of dyslipidemia associated with the impaired glucose tolerance include hypertriglyceridemia, high level of VLDL and low level of HDL cholesterol. They also associate with accumulation of remnant lipoproteins and appearance of small dense LDL. In addition, we pointed out that the increased number of risk factors is associated with elevated insulin and proinsulin level.

Dyslipidemia is considered as an important modifiable risk factor for cardiovascular disease (CVD). The link between childhood dyslipidemia and occurrence of atherosclerosis and its sequels in adulthood are well-documented. This study aimed to systematically review the prevalence of dyslipidemia among Iranian children and adolescents. An electronic search was conducted on studies published from January 1990 to January 2014. The main international electronic data sources were PubMed and the NLM Gateway (for MEDLINE), Institute of Scientific Information (ISI), and SCOPUS. For Persian databases, we used domestic databases with systematic search capability including IranMedex, Irandoc, and Scientific Information Database (SID). We included all available population-based studies and national surveys conducted in the pediatric age group (aged <21 years). In this review, 1772 articles were identified (PubMed: 1464; Scopus: 11; ISI: 58; SID: 90; IranMedex: 149; Irandoc: 57). During three refine steps and after removing of duplicates, 182 articles related to the study domain were selected. After quality assessment, 46 studies were selected for text appraisal, of which 26 qualified articles were evaluated at the final step. The prevalence range of hypercholesterolemia, hypertriglyceridemia, elevated low-density lipoprotein cholesterol, and low high-density lipoprotein cholesterol (HDL-C) were 3-48%, 3-50%, 5-20% and 5-88%, respectively. Low HDL-C and hypertriglyceridemia were the most prevalent lipid disorders in this group of population. Dyslipidemia is a common health problem among Iranian children and adolescents. Few data were available in preschool children. This finding provides useful information for health policy makers to implement action-oriented interventions for prevention and early control of this important CVD risk factor.

The study aims to determine whether dyslipidemia patients living in less affluent neighborhood are at a higher risk of mortality compared to those living in more affluent neighborhoods. A population-based cohort study was conducted using a stratified representative sampling from the National Health Insurance claim data from 2002 to 2013. The target subjects comprise patients newly diagnosed with dyslipidemia receiving medication. We performed a survival analysis using the Cox proportional hazard model. Of 11,946 patients with dyslipidemia, 1053 (8.8%) subjects died during the follow-up period. Of the dyslipidemia patients earning a middle-class income, the adjusted HR in less affluent neighborhoods was higher than that in the more affluent neighborhoods compared to the reference category of high individual SES in more affluent neighborhoods (less affluent; hazard ratio (HR) = 1.64, 95% confidence interval (CI): 1.35-1.99 vs. more affluent; HR = 1.48, 95% CI: 1.20-1.81, respectively). We obtained consistent results in patients with lower income, wherein the adjusted HR in less affluent neighborhoods was higher than that in more affluent neighborhoods (less affluent; HR = 1.52, 95% CI: 1.16-1.97 vs. more affluent; HR = 1.41, 95% CI: 1.04-1.92, respectively). Living in a less affluent neighborhood contributes to higher mortality among dyslipidemia patients. The individual- and neighborhood-level variables cumulatively affect individuals such that the most at-risk individuals include those having both individual- and neighborhood-level risk factors. These findings raise important clinical and public health concerns and indicate that neighborhood SES approaches should be essentially considered in health-care policies similar to individual SES.

Oxidative stress is increased in metabolic syndrome and type 2 diabetes mellitus (T2DM) and this appears to underlie the development of cardiovascular disease, T2DM and diabetic complications. Increased oxidative stress appears to be a deleterious factor leading to insulin resistance, dyslipidemia, β-cell dysfunction, impaired glucose tolerance and ultimately leading to T2DM. Chronic oxidative stress, hyperglycemia and dyslipidemia are particularly dangerous for β-cells from lowest levels of antioxidant, have high oxidative energy requirements, decrease the gene expression of key β-cell genes and induce cell death. If β-cell functioning is impaired, it results in an under production of insulin, impairs glucose stimulated insulin secretion, fasting hyperglycemia and eventually the development of T2DM.

[Consensus for pharmacologic treatment of atherogenic dyslipidemia with statin-fenofibrate combined therapy].

PubMed

2016-01-01

LDLc levels are associated with increase of cardiovascular risk, and statins are currently used for their control. Nevertheless, a despite of LDLc levels at goal, a residual risk is persistent, commonly associated with persistent lipids modifications (high triglycerides and low HDLc). So, it is necessary to evaluate triglycerides and HDL to assessment cardiovascular risk. Clinical data are consistent with efficacy and safety of combination therapy with statin and other lipid lowering drugs, for instance fenofibrate. Patients with hipertriglyceridemia and low HDLc are the group with most potential improve. In that patients with atherogenic dyslipidemia, the target for therapeutic objectives related with non-HDL-cholesterol is a priority, because non-HDL-cholesterol is considered as a more accuracy measure to assessment cardiovascular risk.

Mulberry leaf is well known for its several biological effects. The purpose of this study was to evaluate the hypolipidemic effect of mulberry leaf in non-diabetic patients with mild dyslipidemia. A within-subjects research design was conducted at the out-patient clinic in Thailand. Twenty-three patients who met the NCEP ATP III criteria guideline for dyslipidemia and failed a 4 week diet therapy were enrolled and assigned to receive three tablets of 280 mg mulberry leaf tablet three times a day before meals for a period of 12 weeks. Routine blood analyses including lipid parameters and liver function tests were performed every 4 weeks. At 4 and 8 weeks of mulberry leaf tablet therapy, triglyceride was significantly decreased by 10.2% (p < 0.05) and 12.5% (p < 0.05), respectively, from baseline. At the end of the study, total cholesterol, triglyceride and LDL were significantly decreased by 4.9% (p < 0.05), 14.1% (p < 0.05) and 5.6% (p < 0.05), respectively, from baseline, whereas HDL was significantly increased by 19.7% (p < 0.05). Even though some patients experienced side effects such as mild diarrhea (26%), dizziness (8.7%) or constipation and bloating (4.3%), mulberry leaf tablet therapy is still capable and safe in reducing cholesterol levels and enhancing HDL in patients with mild dyslipidemia.

Childhood dyslipidemia is a critical factor of lifelong health. Therefore, screening and controlling dyslipidemia from childhood is a practical healthy strategy. However, few studies have examined the performance of anthropometric predictors of dyslipidemia in Chinese children, let alone the potential gender and urban-rural disparity. Thus, we evaluated anthropometric indices predicting dyslipidemia by genders and living areas in Chinese children. Data were from a health and nutrition survey conducted in seven urban areas and two rural areas in China between 2011 and 2012. The serum lipid levels of the participants were compared between genders and living areas. The body mass index z-score (BMI z-score), waist-hip ratio (WHR), waist-height ratio (WHtR), and mid-upper arm height ratio (MaHtR) were used as predictors. The receiver operating characteristic (ROC) analysis was performed to investigate the ability of anthropometric indices predicting dyslipidemia. A total of 773 participants (average age = 9.3 ± 1.7 y) were included. The prevalence of dyslipidemia was 10.9%. Anthropometric indices were all significantly related to blood lipid profiles in boys after adjustment for age. The areas under the ROC curves (ACUs) were significantly larger than 0.5 in boys (ranged between 0.66-0.73), and were larger in rural boys (ranged between 0.68 and 0.94). MaHtR and WHR were associated with the highest specificity (93.8%) and highest sensitivity (100%), respectively. Using anthropometric indices, screening for dyslipidemia may be more appropriate in boys than in girls in China, especially in rural boys. The BMI z-score, WHR, WHtR, and MaHtR were all significantly associated with dyslipidemia in boys; using WHR and MaHtR as indicators achieved the highest sensitivity and specificity, respectively.

Diabetic dyslipidemia is one of the leading causes of coronary artery disease (CAD) death. Genetic and environmental factors play an important role in the development of type 2 diabetes mellitus (T2DM) and dyslipidemia. The present study was aimed to investigate the association of ACE (rs4646994), FABP2 (rs1799883), MTHFR (rs1801133) and FTO (rs9939609) genes polymorphism in T2DM with dyslipidemia. Totally, 559 subjects including 221 T2DM cases with dyslipidemia, 158 T2DM without dyslipidemia and 180 controls were enrolled. ACE genes polymorphism was evaluated by polymerase chain reaction (PCR), while MTHFR , FABP2 , FTO genes polymorphisms were evaluated by PCR and restriction fragment length polymorphism (RFLP). Significant association of ACE and MTHFR genes polymorphisms were found in both group of cases [T2DM with dyslipidemia (P<0.001, and P=0.008, respectively) and T2DM without dyslipidemia (P=0.003, and P=0.010, respectively)] while FABP2 and FTO genes polymorphisms were significantly associated with T2DM without dyslipidemia (P=0.038, and P= 0.019, respectively). This study concludes that ACE , FABP2 , FTO and MTHFR genes are associated with T2DM. Additionally, it also seems that ACE and MTHFR genes might be further associated with the development of dyslipidemia in T2DM cases.

This review summarizes the main provisions of the new, issued in 2016, recommendations of the European Society of Cardiology and Atherosclerosis Society in cooperation with the European Association on Cardiovascular Prevention and Rehabilitation on Cardiovascular disease prevention and Management of dyslipidemia. In these recommendations, the following trends can be traced distinctly: priority in primary prevention is given to non-drug methods of influence; targets of hypolipidemic therapy are identified not only for low density lipoprotein (LDL) cholesterol (CH), but also for non-high density lipoprotein (HDL) CH, especially in cases of concomitant hypertriglyceridemia. In the field of therapy, in which statins remain the main tool of correction of hyperlipidemia, it is recommended to more widely resort to the use of combination therapy, especially in cases of familial hypercholesterolemia or intolerance to statins; introduction of a new class of drugs- inhibitors of proprotein convertase subtilisin/kexin type 9 makes it possible to further reduce the level of LDLCH, lipoprotein(a) more than 60%. Regarding the wider application of these drugs there are issues related to the relatively limited experience of their use and the lack of data on long-term results and the incidence of side effects. Much attention is paid to more active correction of dyslipidemia in elderly patients, patients with chronic renal failure, diabetes, and several other diseases. The emergence of new European recommendations will undoubtedly serve as a stimulus to the revision of the Russian recommendations, which remain unchanged from 2012.

Diabetic dyslipidemia contributes to an increased risk of cardiovascular disease. Hence, its treatment is necessary to reduce cardiovascular events. Honey reduces hyperglycemia and dyslipidemia. The reproducibility of these beneficial effects and their generalization to honey samples of other geographical parts of the world remain controversial. Currently, data are limited and findings are inconclusive especially with evidence showing honey increased glycosylated hemoglobin in diabetic patients. It was hypothesized that this deteriorating effect might be due to administered high doses. This study investigated if Nigerian honey could ameliorate hyperglycemia and hyperlipidemia. It also evaluated if high doses of honey could worsen glucose and lipid abnormalities. Honey (1.0, 2.0 or 3.0 g/kg) was administered to diabetic rats for three weeks. Honey (1.0 or 2.0 g/kg) significantly (p < 0.05) increased high density lipoprotein (HDL) cholesterol while it significantly (p < 0.05) reduced hyperglycemia, triglycerides (TGs), very low density lipoprotein (VLDL) cholesterol, non-HDL cholesterol, coronary risk index (CRI) and cardiovascular risk index (CVRI). In contrast, honey (3.0 g/kg) significantly (p < 0.05) reduced TGs and VLDL cholesterol. This study confirms the reproducibility of glucose lowering and hypolipidemic effects of honey using Nigerian honey. However, none of the doses deteriorated hyperglycemia and dyslipidemia.

Estrogen has an impact on the type of lipoproteins and the blood lipid levels, thus protecting the cardiovascular system. Postmenopausal breast cancer patients suffer a significant decrease in estrogen levels due to both physiological changes and the use of drugs, and thus have a higher risk of atherosclerotic cardiovascular diseases. Therefore, strict lipid management is required for postmenopausal breast cancer patients receiving endocrine therapy. However, no guidelines have been developed in terms of lipid management and intervention for postmenopausal breast cancer patients. The Chinese expert group of multidisciplinary management of dyslipidemia in breast cancer patients with endocrine therapy, after deep investigation into the management of dyslipidemia in postmenopausal patients with early-stage breast cancer, has developed the China Expert Consensus on Dyslipidemia Management in Postmenopausal Patients with Early-stage Breast Cancer. The Consensus clearly defines the goals and measures of interventions for dyslipidemia, hoping to effectively reduce the risk of atherosclerotic cardiovascular disease in postmenopausal breast cancer patients and further improve the long-term survival of the patients.

Dyslipidemia is recognized as a major cause of cardiovascular disease. A number of evidence-based guidelines recommend conventional synthetic drugs as standard therapy for dyslipidemia in clinical practice. However, antihyperlipidemic drugs have some serious side effects. Naturally derived dietary supplements are becoming attractive as an alternative strategy because of their high efficacy and safety, as supported by numerous data. Moreover, they could be considered an initial treatment for dyslipidemia. The aims of this literature review were to demonstrate the efficacy, safety, and clinical implications of dietary supplements for treating dyslipidemia. We reviewed the literature, including data from in vitro, in vivo, and human studies, and clinical guideline recommendations. We classified dietary supplements by their proposed mechanisms of action on lipid metabolism and also collected daily dosage recommendations, interactions with concurrent drugs and/or foods, dosage forms, and examples of commercially available products. Various types of naturally derived dietary supplements exhibit lipid-improving properties. Efficacy and safety are acceptable; however, their use in clinical practice will require further well-designed investigations and the support of scientific data.

To determine the prevalence of dyslipidemia in students from the primary and middle schools and the influential factors, and to provide evidence for the prevention and control of dyslipidemia and relevant chronic diseases in primary and middle schools. 
 Methods: A total of 2 028 students aged 7 to 17 from the primary and middle schools in Changsha were selected by stratified random cluster sampling. The contents of the study included questionnaire survey, physical measurement and blood tests for fasting blood triglyceride (TG), total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), and high-density lipoprotein cholesterol (HDL-C) levels. Non-high-density lipoprotein cholesterol (non-HDL-C) level was calculated by TC level minus HDL-C level. Chi-square test and non-conditional logistic regression model were used to analyze the factors that contributed to dyslipidemia.
 Results: The dyslipidemia rate was 18.6%, and the abnormal rates of TG, TC, LDL-C, non-HDL-C and HDL-C were 6.8%, 5.6%, 2.3%, 4.2% and 8.6%, respectively. By chi-square test, the dyslipidemia rate in students with different ages, home locations, BMI groups, central obesity, time on watching TV or playing computer per day, and daily sleep time was statistically significant. Non-conditional logistic regression analysis showed that home location for the city (OR=1.332), overweight (OR=1.548), obesity (OR=2.201), central obesity (OR=1.695), watching TV or playing computer for more than 2 hours per day (OR=1.357), daily sleep time longer than 11 hours (OR=2.518) were the risk factors for dyslipidemia in students from the primary and middle schools. 
 Conclusion: Nearly 1/5 primary and middle school students show dyslipidemia, which is associated with obesity and other bad behaviors.

The scale and variables linked to bariatric surgery's effect on dyslipidemia have not been conclusive. To compare the effect of Roux-en-Y gastric bypass (RYGB), sleeve gastrectomy (SG), and adjustable gastric banding (LAGB) on dyslipidemia SETTING: National bariatric surgery registry. Plasma lipids and associated variables were compared at baseline and 1 year (12±4 mo) after surgery for registry patients with dyslipidemia enrolled from June 2013 to August 2014. The greatest mean total-cholesterol (TC) reduction was observed post-RYGB, 226.7±26.4 to 181.3±30.9 mg/dL (19.9%, n = 208), followed by post-SG, 227.9±24.4 to 206.7±34.2 mg/dL (8.9%, n = 1515; P<.001). Normal TC levels of below 200 mg/dL were achieved by 76% post-RYGB patients compared with 43.5% post-SG patients (odds ratio [OR] = 6.24, 95% confidence interval [CI]: 3.69-10.53) and 25.6% post-LABG patients (OR = 9.66, 95% CI: 4.11-22.67; P<.01). Although equivalent patterns were observed for low-density-lipoprotein cholesterol (LDL), the levels of high-density-lipoprotein cholesterol (HDL) were most improved post-SG, reaching normal levels in 58.1% of SG male patients versus 39.5% of RYGB male patients (OR = 1.56, 95% CI: 1.04-2.35), (P = .02). The lowering of triglyceride levels by approximately 75% was comparable after SG and RYGB procedures. The type of surgery was the strongest independent predictor for all lipid level improvements or remissions. Male sex was an independent predictor for LDL normalization only (OR = 1.88, 95% CI: 1.24-2.85). Excess weight loss offered no meaningful prediction for lipid improvement (OR = 1.01-1.03). Particular types of bariatric surgeries had different effects on dyslipidemia, independent of weight loss. Overall, the RYGB achieved the biggest reduction in plasma lipids (TC and LDL), although SG did affect HDL. Our results could aid in the decision-making process regarding the most appropriate procedure for patients with dyslipidemia. Copyright © 2017 American

The relevance of serum apolipoprotein E (apoE) levels to two hypertriglyceridemic dyslipidemias has not been clarified. We explored, in a cross-sectional (and short-term prospective) evaluation, the independent relationship of serum apoE to the atherogenic dyslipidemia, hypertriglyceridemia with elevated apoB (HtgB) and to apoA-I dysfunctionality, previously shown in Turkish adults to be independent of apoE genotype. Serum apoE concentrations were measured by immunonephelometry in 1,127 middle-aged adults. In multivariable regression analysis, apoE concentrations showed log-linear associations with apoB and apoA-I levels, waist circumference, independent of C-reactive protein (CRP), homeostatic model assessment (HOMA) index and other confounders. The likelihood of atherogenic dyslipidemia and of HtgB roughly tripled per 1-SD increment in apoE concentrations, additively to apoE genotype, HOMA, apoA-I, CRP concentrations and waist circumference; yet apoA-I, protective against atherogenic dyslipidemia, appeared to promote HtgB, a finding consistent with apoA-I dysfunctionality in this setting. Each 1-SD increment in the apoE level was moreover, associated in both genders with MetS (at OR 1.5), after adjustment for sex, age, apoB, apoA-I and CRP, or for apoE genotypes. Circulating apoE predicted in both genders age-adjusted prevalent and incident coronary heart disease (CHD), independent of apoE genotype and CRP (OR 1.32 [95 % CI 1.11; 1.58]). To conclude, in a general population prone to MetS, elevated apoE concentrations are strongly linked to HtgB and atherogenic dyslipidemia, irrespective of apoE genotype, are associated with MetS and CHD. Excess apoE reflects pro-inflammatory state and likely autoimmune activation.

Few studies have examined the longitudinal associations of fitness or changes in fitness on the risk of developing dyslipidemias. This study examined the associations of (1) baseline fitness with 25-year dyslipidemia incidence and (2) 20-year fitness change on dyslipidemia development in middle age in the Coronary Artery Risk Development in Young Adults Study (CARDIA). Multivariable Cox proportional hazards regression models were used to test the association of baseline fitness (1985-1986) with dyslipidemia incidence over 25 years (2010-2011) in CARDIA (N=4,898). Modified Poisson regression models were used to examine the association of 20-year change in fitness with dyslipidemia incidence between Years 20 and 25 (n=2,487). Data were analyzed in June 2014 and February 2015. In adjusted models, the risk of incident low high-density lipoprotein cholesterol (HDL-C); high triglycerides; and high low-density lipoprotein cholesterol (LDL-C) was significantly lower, by 9%, 16%, and 14%, respectively, for each 2.0-minute increase in baseline treadmill endurance. After additional adjustment for baseline trait level, the associations remained significant for incident high triglycerides and high LDL-C in the total population and for incident high triglycerides in both men and women. In race-stratified models, these associations appeared to be limited to whites. In adjusted models, change in fitness did not predict 5-year incidence of dyslipidemias, whereas baseline fitness significantly predicted 5-year incidence of high triglycerides. Our findings demonstrate the importance of cardiorespiratory fitness in young adulthood as a risk factor for developing dyslipidemias, particularly high triglycerides, during the transition to middle age.

Dyslipidemia is a major risk factor for cardiovascular disease. Prevalence patterns and determinants of dyslipidemia in Sri Lanka are unkown. We aimed to determine the prevalence and correlates of dyslipidemia among Sri Lankan adults. A nationally representative sample was recruited by multistage random cluster sampling in Sri Lanka Diabetes and Cardiovascular Study, a cross-sectional study. Data collected by an interviewer-administered questionnaire, physical examination, anthropometric measurements lipid analysis from take 12-hour fasting blood samples were used. Among 4451 participants 60.5% were women and mean age was 46 years. Mean (standard deviation) total cholesterol (TC), high-density lipoprotein cholesterol (HDLC), low-density lipoprotein cholesterol (LDLC), triglycerides (TGs), and TC/HDLC levels were 206.7 mg/dL (±43.5), 46.8 mg/dL (±10.6), 135.5 mg/dL (±37.6), 121.7 mg/dL (±66.8), and 4.6 (±1.1), respectively. Women had higher mean TC, HDLC, LDLC, and TG values compared to men across all age groups. Mean TC, LDLC, and TGs increased with age in both genders; 77.4% of participants had some form of dyslipidemia. Low HDLC was the commonest type (49.6%) of dyslipidemia. Increasing age, female sex, living in urban sector, high body mass index, central obesity, diabetes, hypertension, insufficient physical activity, and smoking were associated with having some form of dyslipidemia. Three in four Sri Lankan adults have some form of dyslipidemia. Physical inactivity, obesity, hypertension, and diabetes are the leading modifiable risk factors.

Dyslipidemia, a well-known risk factor for cardiovascular disease, is common in patients with kidney disease. Recent studies discerned that dyslipidemias play a critical role in renal damage progression in renal diseases, but the association between dyslipidemias and chronic kidney disease (CKD) in the general population remains unknown. Thus, we assessed whether the growing prevalence of dyslipidemia could increase the risk of CKD. A total of 4779 middle-aged and elderly participants participated in this study. Dyslipidemias were defined by the 2007 Guidelines in Chinese Adults. Incident CKD was defined as albuminuria and/or reduced estimated glomerular filtration rate (eGFR, < 60 ml×min(-1)×1.73 m(-2)). Regression analysis was used to evaluate the association between dyslipidemia and albuminuria/reduced eGFR. Participants with hypercholesterolemia exhibited a greater prevalence of albuminuria and reduced eGFR (10.0% vs. 6.1%, P = 0.001; 4.0% vs. 2.4%, P = 0.028, respectively). Both hypercholesterolemia and low high density lipoprotein cholesterol (HDL-C) were independently associated with albuminuria (odds ratio (OR) 1.49; 95% confidence interval (CI) 1.08 - 2.07 and OR 1.53; 95%CI 1.13 - 2.09, respectively). The multivariable adjusted OR of reduced eGFR in participants with hypercholesterolemia was 1.65 (95%CI 1.03 - 2.65). As the number of dyslipidemia components increased, so did the OR of CKD: 0.87 (95%CI 0.65 - 1.15), 1.29 (95%CI, 0.83 - 2.01), and 7.87 (95%CI, 3.75 - 16.50) for albuminuria, and 0.38 (95%CI 0.21 - 0.69), 1.92 (95%CI 1.14 - 3.25), and 5.85 (95%CI 2.36 - 14.51) for reduced eGFR, respectively. Our findings indicate that dyslipidemias increase the risk of CKD in the middle-aged and elderly Chinese population. Hypercholesterolemia plays an important role in reducing total eGFR. Both low HDL-C and hypercholesterolemia are associated with an increased risk for albuminuria.

Dyslipidemias are defined as changes in lipid metabolism that have abnormal concentrations of lipids or lipoproteins in the bloodstream. Chronic increase in triglyceride and low-density lipoprotein (LDL-c) levels are known as risk factors for the atherogenesis process as well as other cardiovascular diseases (CVDs). The magnitude of the problems caused by dyslipidemias impels research by new agents that act in the prevention and control. Thus, products from the Amazonian biodiversity, such as Euterpe oleracea oil (OFEO), rich in unsaturated fatty acids (UFAs), constitutes a study source for the treatment of alterations in lipid metabolism. The present study aims to investigate the effect of OFEO treatment in rats with Triton-induced dyslipidemia (Tyloxapol WR1339). The physicochemical and chromatographic results confirmed the chemical composition of OFEO with a predominance of UFAs (67.83%), with Oleic acid being the majority (54.32%). At Triton-induced dyslipidemia, the animals treated with OFEO and Simvastatin showed a significant reduction in total cholesterol levels, with values ​​of 121.7±29.5 (p<0.01) and 96.6±17.6mg/dL (p<0.001), respectively. OFEO also significantly reduced LDL-c levels (p<0.01) and triglycerides (p<0.001). OFEO and Simvastatin improved the lipid profile by significantly increasing (p<0.05) the high-density lipoprotein (HDL) values. Therefore, it is concluded that the OFEO treatment used in the conditions of this study had a beneficial effect on dyslipidemia, acting as antihypercholesterolemic and antihypertriglyceridemic, thus possibly contributing as a preventive agent for CVDs.

To explore the prevalence and ethnic differences of osteosarcopenic obesity (OSO) and dyslipidemia and their relationship among Maonan, Mulam, Hmong, and Yao minorities in China. A total of 2315 Maonan, Mulam, Hmong, and Yao women aged 20-95 from Guangxi were included in this study. Questionnaire survey was carried out and their blood lipids were tested. Body compositions were measured by bioelectrical impedance analysis, and T-score was assessed by ultrasonic examination, respectively. Our study showed ethnic-specific prevalence of OSO. In older women, the incidence rates of OSO in Mulam were 4.9, 12.6, and 11.5% in Maonan, Mulam, and Hmong ethnicity, respectively. In younger group, the incidence rates of OSO were 0.4, 0.4, and 0.6%, respectively. However, there is no prevalence of OSO in Yao women in two groups. The prevalence of dyslipidemia in younger women was 22.86, 29.89, 43.35, and 80.00% in group numbering one, two, and three, respectively. In older women, it was 29.13, 39.02, 41.37, and 52.38%, respectively. Based on logistic regression analysis, after controlling for covariates, dyslipidemia in younger group was positively associated with a higher number of adverse body composition, especially for OSO (OR = 12.53, 95%CI 1.34-116.99). Compared with normal women, OSO women in older group were also more likely to have dyslipidemia (OR = 6.75, 95%CI 3.19-14.31). OSO may be a risk factor for dyslipidemia in the ethnic groups. Thus, efforts to promote healthy aging should be focused on preventing obesity and maintaining bone health and muscle mass.

A high percentage of type 2 diabetes mellitus (T2D) patients are also affected by dyslipidemia and chronic periodontitis (CP), but no studies have determined the gene expression in patients that are simultaneously affected by all three diseases. We investigated the systemic expression of immune-related genes in T2D, dyslipidemia, and CP patients. One hundred and fifty patients were separated into five groups containing 30 individuals each: (G1) poorly controlled T2D with dyslipidemia and CP; (G2) well-controlled T2D with dyslipidemia and CP; (G3) normoglycemic individuals with dyslipidemia and CP; (G4) healthy individuals with CP; (G5) systemic and periodontally healthy individuals. Blood analyses of lipid and glycemic profiles were carried out. The expression of genes, including IL10, JAK1, STAT3, SOCS3, IP10, ICAM1, IFNA, IFNG, STAT1, and IRF1, was investigated by RT-qPCR. Patients with dyslipidemia demonstrated statistically higher expression of the IL10 and IFNA genes, while IFNG, IP10, IRF1, JAK1, and STAT3 were lower in comparison with nondyslipidemic patients. Anti-inflammatory genes, such as IL10 , positively correlated with parameters of glucose, lipid, and periodontal profiles, while proinflammatory genes, such as IFNG , were negatively correlated with these parameters. We conclude that dyslipidemia appears to be the primary disease that is associated with gene expression of immune-related genes, while parameters of T2D and CP were correlated with the expression of these important immune genes.

To find the cure of world's one of the leading morbid and mortal disorders; diabetes mellitus and its most prevalent complication, 'diabetic-dyslipidemia', is one of the leading health challenges of 21st century. The use of phytomedicine is a glimmer of hope in this scenario. Studies of current decade have shown that methanolic extracts of Zingiber officinale and Curcuma longa have highly effective therapeutic potentials against the aforesaid disorders, however, which of the extracts has more potential is still unclear. Furthermore, synergistic effect of the extracts has never been studied. Forty-eight Albino adult rats of either sex were randomly divided into eight groups. A-D groups were containing healthy rats while E-H groups were of induced diabetic-dyslipidemic rats. For forty-two days, rats of each group were given either distilled water or Zingiber officinale methanolic extract (ZOME) or Curcuma longa methanolic extract (CLME) or ZOME+CLME therapies at dose rate of 300mg/100 mL dist. H 2 O/kg body wt/day. FPG and lipid profiles were estimated before and after the trial, and were statistically analyzed by one-way ANOVA along with Post-hoc Tukey's multiple comparison tests. Although, ZOME and CLME significantly (P<0.05) lowered fasting plasma glucose (FPG) levels and controlled lipid profiles in diabetic-dyslipidemic rats; yet, synergistic therapy of both extracts (ZOME+CLME) most significantly (P<0.05) controlled all parameters of diabetic-dyslipidemia (78.00±1.06mg/dL FPG, 62.00±0.58mg/dL TG, 66.50±0.76mg/dL cholesterol, 32.00±0.36mg/dL HDL, 22.43±0.64 mg/dL LDL, and 12.40±0.12mg/dL VLDL). Our findings may be useful to formulate new medicines having multiple potentials to control diabetes mellitus, dyslipidemia, and diabetic-dyslipidemia.

This study aimed to present the current information on the genetic background of dyslipidemias and provide insights into the complex pathophysiological role of several plasma lipids/lipoproteins in the pathogenesis of atherosclerotic cardiovascular disease. Furthermore, we aim to summarize established therapies and describe the scientific rationale for the development of novel therapeutic strategies. Evidence from genetic studies suggests that besides lowering low-density lipoprotein cholesterol, pharmacological reduction of triglyceride-rich lipoproteins, or lipoprotein(a) will reduce risk for coronary heart disease. Dyslipidemia, in particular hypercholesterolemia, is a common clinical condition and represents an important determinant of atherosclerotic vascular disease. Treatment decisions are currently guided by the causative lipid phenotype and the presence of other risk factors suggesting a very high cardiovascular risk. Therefore, the identification of lipid disorders and the optimal combination of therapeutic strategies provide an outstanding opportunity for reducing the onset and burden of cardiovascular disease.

Objective: To understand the prevalence of dyslipidemia and normal blood lipids level in Uygur diabetes patients in Kashgar prefecture in southern area of Xinjiang. Methods: A total of 5 078 local residents aged ≥18 years (42.56 % were men) selected through cluster random sampling in Kashgar were surveyed by means of questionnaire survey, physical examination and laboratory test, and 521 diabetes patients were screened. Results: The overall prevalence of dyslipidemia in diabetes patients was 59.50 % (310/521) with adjusted rate as 49.39 % . Age ≥65 years, overweight, obesity and abdominal obesity increased the risk for dyslipidemia by 0.771 times (95 % CI : 1.015-3.088), 1.132 times (95 % CI : 1.290-3.523), 1.688 times (95 % CI : 1.573-4.592) and 0.801 times (95 % CI : 1.028-3.155) respectively. Compared with males, female was a protective factor for dyslipidemia ( OR =0.507, 95 %CI : 0.334-0.769). The overall normal rate of blood lipids level including total cholesterol (TC), triglycerides (TG), high-density lipoprotein cholesterol (HDL-C) and low-density lipoprotein cholesterol (LDL-C) for type 2 diabetes patients was 11.13 % . Female, higher BMI and abdominal obesity were the factors influencing the overall normal blood lipids level. The normal rate of LDL-C level decreased with increase of age, BMI and waist circumferences (trend test χ (2)=18.049, P <0.001; trend test χ (2)=10.582, P =0.001; χ (2)=19.081, P <0.001), but increased with educational level (trend test χ (2)=9.764, P =0.002). Conclusion: The prevalence of dyslipidemia in Uygur diabetes patients in Kashgar was high, however, the overall normal rate of blood lipid level was relatively low. Obesity was the most important risk factor for dyslipidemia in this area. More attention should be paid to dyslipidemia prevention in women.

Overweight is one of the major public health problems in Brazil; it is associated with dyslipidemia, which is an important risk factor for cardiovascular diseases. To evaluate the lipid profile of residents of the municipality of São Paulo, state of São Paulo, according to the nutritional status. Data from the population-based cross-sectional study ISA-Capital 2008 on a sample of residents of São Paulo were used. Participants were categorized into groups according to body mass index and age range. The levels of total cholesterol, HDL-cholesterol, LDL-cholesterol, triglycerides, and non-HDL cholesterol were measured. The association between lipid profile, nutricional status, and waist circumference was investigated. The data were processed using the survey mode of the Stata 11.0 software. The prevalence of any type of dyslipidemia in the population was 59.74%, with low HDL-cholesterol dyslipidemia being the most common type. Not overweight individuals had higher mean levels of HDL-cholesterol and lower levels of LDL-cholesterol, total cholesterol, triglycerides, and non-HDL cholesterol when compared with the overweight group. The rate of inadequacy of these variables was higher in the overweight individuals, regardless of the age group, to the exception of LDL-cholesterol in the adults and elderly. A higher prevalence of isolated hypertriglyceridemia was observed in individuals with higher waist circumference among the adults and the total population. The results indicate an association between dyslipidemia and overweight in the population of the city of São Paulo. The most prevalent dyslipidemia in this population was low HDL-cholesterol.

Background Exome sequencing is a promising tool for gene mapping in Mendelian disorders. We utilized this technique in an attempt to identify novel genes underlying monogenic dyslipidemias. Methods and Results We performed exome sequencing on 213 selected family members from 41 kindreds with suspected Mendelian inheritance of extreme levels of low-density lipoprotein (LDL) cholesterol (after candidate gene sequencing excluded known genetic causes for high LDL cholesterol families) or high-density lipoprotein (HDL) cholesterol. We used standard analytic approaches to identify candidate variants and also assigned a polygenic score to each individual in order to account for their burden of common genetic variants known to influence lipid levels. In nine families, we identified likely pathogenic variants in known lipid genes (ABCA1, APOB, APOE, LDLR, LIPA, and PCSK9); however, we were unable to identify obvious genetic etiologies in the remaining 32 families despite follow-up analyses. We identified three factors that limited novel gene discovery: (1) imperfect sequencing coverage across the exome hid potentially causal variants; (2) large numbers of shared rare alleles within families obfuscated causal variant identification; and (3) individuals from 15% of families carried a significant burden of common lipid-related alleles, suggesting complex inheritance can masquerade as monogenic disease. Conclusions We identified the genetic basis of disease in nine of 41 families; however, none of these represented novel gene discoveries. Our results highlight the promise and limitations of exome sequencing as a discovery technique in suspected monogenic dyslipidemias. Considering the confounders identified may inform the design of future exome sequencing studies. PMID:25632026

Psoriasis is a chronic inflammatory disease of multifactorial etiology, with participation of genetic, autoimmune and environmental factors. Recent studies have demonstrated the role of inflammatory cells and mediators in the pathogenesis of psoriasis, which is now defined as a systemic and autoimmune inflammatory disease that may be associated with other diseases of inflammatory nature. To evaluate the occurrence of obesity and dyslipidemia in patients with psoriasis treated at a dermatology clinic in Manaus. We performed a prospective descriptive study to assess the prevalence of obesity and dyslipidemia in patients with psoriasis. Besides the recommended dermatological care, a physical examination was performed to measure weight, height and waist circumference. We included 72 patients, 44 (61.1%) female and 28 (38.9%) male, with a mean age of 51.0 years ± 15.9 years. As for body mass index (BMI), 16 (22.2%) were overweight and 20 (27.8%) were obese. In the analysis of waist circumference in relation to gender, we found that 79.5% of women surveyed had central obesity, a percentage statistically higher than that observed among men (42.9%) at the 5% level of significance (p = 0.001). Regarding the diagnosis of dyslipidemia, 29 (65.9%) females and 22 (78.6%) males showed alterations in lipid profile. The occurrence of dyslipidemia and obesity in patients with psoriasis can affect life quality and expectancy, increasing the risk of systemic and metabolic diseases, which makes periodic investigation of these comorbidities in patients with psoriasis mandatory.

Background and Objectives: The increasing frequency of cardiovascular disease (CVD) rests on the presence of major cardiovascular risk factors including dyslipidemia. This dyslipidemia is also a target for the prevention and treatment of many cardiovascular diseases. Hence, identification of individuals at risk of CVD is needed for early identification and prevention. The study was carried out to evaluate dyslipidemia using the lipid ratios and indices instead of just the conventional lipid profile. Methodology: It was a cross-sectional study with 699 participants recruited from semi-urban communities in Nigeria. Anthropometric indices, blood pressure, and fasting lipid profiles were determined. Abnormalities in lipid indices and lipid ratios with atherogenic index were also determined. SPSS software version 17.0 were used for analysis, P < 0.05 was considered statistically significant. Results: There were 699 participants with a mean age of 64.45 ± 15.53 years. Elevated total cholesterol, high low-density lipoprotein-cholesterol, elevated triglyceride, and low high-density lipoprotein were seen in 5.3%, 19.3%, 4.4%, and 76.3% of the participants, respectively. The Castelli's risk index-I (CRI-I) predicted the highest prevalence of predisposition to cardiovascular risk (47.8%) with females being at significantly higher risk (55.2% vs. 29.3%, P < 0.001). Atherogenic coefficient, CRI-II, CHOLIndex, atherogenic index of plasma (AIP) predicted a cardiovascular risk prevalence of 22.5%, 15.9%, 11.2%, and 11.0%, respectively, with no significant difference in between the sexes. Conclusions: Serum lipid ratios and AIP may be used in addition to lipid parameters in clinical practice to assess cardiovascular risks even when lipid profiles are apparently normal. AIP was more gender specific amidst the lipid ratios. PMID:27853034

Dyslipidemia is common in women with polycystic ovary syndrome (PCOS) irrespective of age. Our aim was to investigate soluble tumor necrosis factor like weak inducer of apoptosis (sTWEAK), a cardiovascular risk marker in PCOS, and to determine if it is associated with dyslipidemia in youth. A prospective-observational study was carried out including 35 PCOS patients and 35 healthy controls. Serum sTWEAK levels were measured using commercially available kits. Multiple logistic regression analysis was then performed to verify the statistically significant differences in the possible predictors of dyslipidemia. Serum sTWEAK levels and the percentage of women with dyslipidemia were significantly higher in the PCOS group (p = 0.024 and p < 0.001, respectively). Participants were further divided into 2 subgroups based on the presence of dyslipidemia. The percentage of women with PCOS was significantly higher in the dyslipidemic group when compared with controls; 70.7 vs. 20.7%, respectively (p < 0.001). Multiple logistic regression analysis revealed that both the presence of PCOS (OR 7.924, 95% CI 2.117-29.657, p = 0.002) and increased levels of sTWEAK (>693 pg/ml; OR 3.810, 95% CI 1.075-13.501, p = 0.038) were independently associated with dyslipidemia. Increased levels of both sTWEAK and PCOS were found to be independently associated with dyslipidemia in youth. © 2016 S. Karger AG, Basel.

Treatment Strategy for Dyslipidemia in Cardiovascular Disease Prevention: Focus on Old and New Drugs

2018-01-01

Prevention and treatment of dyslipidemia should be considered as an integral part of individual cardiovascular prevention interventions, which should be addressed primarily to those at higher risk who benefit most. To date, statins remain the first-choice therapy, as they have been shown to reduce the risk of major vascular events by lowering low-density lipoprotein cholesterol (LDL-C). However, due to adherence to statin therapy or statin resistance, many patients do not reach LDL-C target levels. Ezetimibe, fibrates, and nicotinic acid represent the second-choice drugs to be used in combination with statins if lipid targets cannot be reached. In addition, anti-PCSK9 drugs (evolocumab and alirocumab) provide an effective solution for patients with familial hypercholesterolemia (FH) and statin intolerance at very high cardiovascular risk. Recently, studies demonstrated the effects of two novel lipid-lowering agents (lomitapide and mipomersen) for the management of homozygous FH by decreasing LDL-C values and reducing cardiovascular events. However, the costs for these new therapies made the cost–effectiveness debate more complicated. PMID:29361723

Dyslipidemia represents a major health issue in psychiatry. We determined whether weighted polygenic risk scores (wPRSs) combining multiple single-nucleotide polymorphisms (SNPs) associated with lipid levels in the general population are associated with lipid levels [high-density lipoprotein (HDL), low-density lipoprotein (LDL), total cholesterol (TC), and triglycerides] and/or dyslipidemia in patients receiving weight gain-inducing psychotropic drugs. We also determined whether genetics improve the predictive power of dyslipidemia. The influence of wPRS on lipid levels was firstly assessed in a discovery psychiatric sample (n=332) and was then tested for replication in an independent psychiatric sample (n=140). The contribution of genetic markers to predict dyslipidemia was evaluated in the combined psychiatric sample. wPRSs were significantly associated with the four lipid traits in the discovery (P≤0.02) and in the replication sample (P≤0.03). Patients whose wPRS was higher than the median wPRS had significantly higher LDL, TC, and triglyceride levels (0.20, 0.32 and 0.26 mmol/l, respectively; P≤0.004) and significantly lower HDL levels (0.13 mmol/l; P<0.0001) compared with others. Adding wPRS to clinical data significantly improved dyslipidemia prediction of HDL (P=0.03) and a trend for improvement was observed for the prediction of TC dyslipidemia (P=0.08). Population-based wPRSs have thus significant effects on lipid levels in the psychiatric population. As genetics improved the predictive power of dyslipidemia development, only 24 patients need to be genotyped to prevent the development of one case of HDL hypocholesterolemia. If confirmed by further prospective investigations, the present results could be used for individualizing psychotropic treatment.

Dyslipidemia has been considered as a major risk factor for coronary heart disease. Alternative medicine has a significant role in treatment of dyslipidemia. There are controversial findings regarding the effects of sour tea on dyslipidemia. The aim of this study was to evaluate the impact of aqueous extract of dried calyx of sour tea on polygenic dyslipidemia. This clinical trial was done on 43 adults (30-60 years old) with polygenic dyslipidemia that were randomly assigned to the intervention and control groups. The control group was trained in lifestyle modifications at baseline. The intervention group was trained for lifestyle modifications at baseline and received two cups of sour tea daily, and both groups were followed up for 12 weeks. Lipid profile was evaluated at baseline, and six and 12 weeks following the intervention. In addition, dietary and physical activity assessed at baseline for twelve weeks. Mean concentration of total cholesterol, HDL-C and LDL-C significantly decreased by up to 9.46%, 8.33%, and 9.80%, respectively, after 12 weeks in the intervention group in comparison to their baseline values. However, LDL-C/HDL-C ratio significantly increased by up to 3.15%, following 12 weeks in the control group in comparison to their baseline values. This study showed no difference in lipid profiles between the two groups, except for HDL-C concentrations. sour tea may have significant positive effects on lipid profile of polygenic dyslipidemia subjects and these effect might be attributed to its anthocyanins and inflation factor content. Therefore, sour tea intake with recommended dietary patterns and physical activity can be useful in regulation of lipid profile in patients with polygenic dyslipidemia.

While heavier weight is known to increase the incidence of dyslipidemia, limited data are available on the relationship between weight gain and its development. A total of 2647 males were categorized into the following four groups according to the difference between their self-reported weight at 20 years of age and their measured weight in 1994-95: a loss of ≥5% (decrease), loss of <5% or gain of <5% (no change), gain of ≥5 to <15% (increase) and gain of ≥15% (sizable increase). They were followed up until their 2002-03 health examination. Using the 'no change' group as reference, the multivariable-adjusted odds ratio (adjusted for age, body mass index at 20 years of age, physical activity, smoking and alcohol intake) and 95% confidence interval (95% CI) for the incidence of dyslipidemia were determined using logistic regression models. A total of 1342 participants developed dyslipidemia during the follow-up period. The 'increase' and 'sizable increase' groups had odds ratios for the incidence of dyslipidemia of 1.97 (95% CI, 1.59-2.45) and 2.68 (2.15-3.34), respectively, demonstrating that there was a significant dose-response association between weight gain since 20 years of age and the incidence of dyslipidemia (P < 0.001 for trend). These results suggest that dyslipidemia could be prevented by avoiding weight gain in adulthood. © The Author 2015. Published by Oxford University Press on behalf of Faculty of Public Health.

The beneficial effect of statins for cardiovascular disease (CVD) prevention has been well established. However, the effectiveness among different phenotypes of dyslipidemia has not been confirmed. We evaluated the effect of pravastatin on the incidence of CVD in relation to the phenotype of dyslipidemia. The MEGA Study evaluated the effect of low-dose pravastatin on primary prevention of CVD in 7832 Japanese patients, who were randomized to diet alone or diet plus pravastatin and followed for more than 5 years. These patients were classified into phenotype IIa (n=5589) and IIb (n=2041) based on the electrophoretic pattern for this post hoc analysis. In the diet group there was no significant difference in the incidence of coronary heart disease (CHD), stroke, CVD, and total mortality between the two phenotypes. Phenotype IIb patients, compared to phenotype IIa, had lower levels of high-density lipoprotein cholesterol (HDL-C) and a significantly higher incidence of CVD in relation to a low HDL-C level (<47.5mg/dL; p=0.02). Furthermore, pravastatin decreased the relative risk for each major endpoint in both type IIa and type IIb dyslipidemia. Significant risk reductions were observed for CHD by 38% (p=0.04) and CVD by 31% (p=0.02) in type IIa dyslipidemia but not in phenotype IIb. Pravastatin therapy provided significant risk reductions for CHD and CVD in patients with phenotype IIa dyslipidemia, but not in those with phenotype IIb dyslipidemia.

Objective To examine the role of hypertension, hyperglycemia and dyslipidemia in potentially accounting for obesity-related brain vulnerability in the form of altered cerebral neurochemistry. Design and Methods Sixty-four adults, ages 40 to 60 years, underwent a health screen and proton magnetic resonance spectroscopy (1H MRS) of occipitoparietal grey matter to measure N-acetyl aspartate (NAA), choline (Cho), myo-inositol (mI) and glutamate (Glu) relative to creatine (Cr). The causal steps approach and non-parametric bootstrapping were utilized to assess if fasting glucose, mean arterial pressure or peripheral lipid/lipoprotein levels mediate the relationship between body mass index (BMI) and cerebral neurochemistry. Results Higher BMI was significantly related to higher mI/Cr, independent of age and sex. BMI was also significantly related to two of the proposed mediators, triglyceride and HDL-cholesterol, which were also independently related to increased mI/Cr. Finally, the relationship between BMI and mI/Cr, was significantly attenuated after inclusion of triglyceride and HDL-cholesterol into the model, one at a time, indicating statistical mediation. Conclusions Higher triglyceride and lower HDL levels statistically account for the association between BMI and myo-inositol, pointing towards a potentially critical role for dyslipidemia in the development of cerebral neurochemical alterations in obesity.

A high fat calorie diet is advocated for patients with cystic fibrosis (CF) however the lipid profiles of individuals with CF, including those with CF-related diabetes (CFRD), are not well studied. We conducted a retrospective review of adult CF patients attending St Michael's Hospital between January 2005 and December 2007. 334 patients (77% pancreatic insufficient (PI)) were included in the study. Mean HDL cholesterol was significantly lower in males (p<0.0001) with 44% of males having HDL cholesterol <38.7mg/dL(1mmol/L). Pancreatic sufficient patients were more likely than PI subjects to have total cholesterol >201mg/dL(5.2mmol/L) (p<0.01). 5% of subjects had triglyceride concentrations >195mg/dL(2.2mmol/L). Diabetes was diagnosed in 23% of subjects. Lipid profiles were similar between diabetics and non-diabetics. Total cholesterol and triglycerides both increased with increasing age and increasing BMI (p<0.01). Dyslipidemia occurs in CF patients however no differences in lipid profiles were seen between those with diabetes and those without. Fasting lipids should be monitored in CF patients, particularly those with PS, older age, and high BMI. As survival in CF increases, the prevalence of dyslipidemia may increase resulting in clinically important complications.

In 2011, an expert National Institutes of Health panel published the "Integrated Guidelines for CV Health and Risk Reduction in Children and Adolescents," which recommended screening all children aged 9 to 11 years for dyslipidemia. It is unknown if this guideline is being followed. We surveyed members of the Utah chapter of the American Academy of Pediatrics to determine whether they performed universal lipid screening at well-child visits (WCV) on their patients at 9,10, or 11 years and how comfortable they were with evaluating and/or managing children with dyslipidemia. Of the 118 respondents who practiced primary care, only 18 (15%) screened all children at WCV; 86 (73%) tested "some," most commonly children who were obese or had a positive family history. 18% were unfamiliar with the guidelines; 28% were familiar with the guidelines but felt they were "inappropriate;" 98 (84%) of the respondents said they were "very or somewhat comfortable" evaluating children with dyslipidemia.

What are the relationships between apolipoprotein (apo) A-I and apoB concentrations, the apoB/apoA-I ratio and the prevalences of dyslipidemia and metabolic syndrome (MS) in south-west Chinese women with polycystic ovary syndrome (PCOS). There is a relatively high incidence of dyslipidemia and MS in south-west Chinese women with PCOS, especially in patients without hyperandrogenism. Patients with dyslipidemia are more obese, and have a more adverse glucose and lipid metabolic profile and higher apoB levels and apoB/apoA-I ratio. The increased apoB levels and apoB/A1 ratio and the MS are strongly associated with PCOS, suggesting that there is an increased risk of cardiovascular diseases in these patients. Dyslipidemia and MS have been widely studied in women with PCOS, but to date no data from south-west Chinese subjects have been available. The apoB/apoA-I ratio has been reported to be strongly associated with MS and insulin resistance (IR) and to be a reliable parameter that reflects lipid disturbances and the potential to develop atherosclerosis, but its relationship with PCOS is unclear. DESIGN This case-control study included 406 patients with PCOS and 342 control women between 17 and 40 years of age from a population in south-west China during 2006-2011. The diagnosis of PCOS was based on the revised 2003 Rotterdam criteria. The control group, consisting of women with infertility due to a Fallopian obstruction or the husband's infertility, women undergoing a pre-pregnancy check and healthy volunteers, was recruited from the same hospital during the same period. All women were not taking any medication known to affect carbohydrate or lipid or hormone metabolism for at least 3 months prior to the study, and were studied during the follicular phase of their menstrual cycle. MS was assessed by the National Cholesterol Education Program-Adult treatment Panel (NCEP-ATP) III criteria modified for Asian populations. Dyslipidemia was defined by one or more of the

BACKGROUND Psoriasis is a chronic inflammatory disease of multifactorial etiology, with participation of genetic, autoimmune and environmental factors. Recent studies have demonstrated the role of inflammatory cells and mediators in the pathogenesis of psoriasis, which is now defined as a systemic and autoimmune inflammatory disease that may be associated with other diseases of inflammatory nature. OBJECTIVES To evaluate the occurrence of obesity and dyslipidemia in patients with psoriasis treated at a dermatology clinic in Manaus. METHODS We performed a prospective descriptive study to assess the prevalence of obesity and dyslipidemia in patients with psoriasis. Besides the recommended dermatological care, a physical examination was performed to measure weight, height and waist circumference. RESULTS We included 72 patients, 44 (61.1%) female and 28 (38.9%) male, with a mean age of 51.0 years ± 15.9 years. As for body mass index (BMI), 16 (22.2%) were overweight and 20 (27.8%) were obese. In the analysis of waist circumference in relation to gender, we found that 79.5% of women surveyed had central obesity, a percentage statistically higher than that observed among men (42.9%) at the 5% level of significance (p = 0.001). Regarding the diagnosis of dyslipidemia, 29 (65.9%) females and 22 (78.6%) males showed alterations in lipid profile. CONCLUSIONS The occurrence of dyslipidemia and obesity in patients with psoriasis can affect life quality and expectancy, increasing the risk of systemic and metabolic diseases, which makes periodic investigation of these comorbidities in patients with psoriasis mandatory.

Dyslipidemia is a major modifiable risk factor for cardiovascular disease. We examined whether the addition of novel single-nucleotide polymorphisms for blood lipid levels enhances the prediction of adult dyslipidemia in comparison to childhood lipid measures. Two thousand four hundred and twenty-two participants of the Cardiovascular Risk in Young Finns Study who had participated in 2 surveys held during childhood (in 1980 when aged 3-18 years and in 1986) and at least once in a follow-up study in adulthood (2001, 2007, and 2011) were included. We examined whether inclusion of a lipid-specific weighted genetic risk score based on 58 single-nucleotide polymorphisms for low-density lipoprotein cholesterol, 71 single-nucleotide polymorphisms for high-density lipoprotein cholesterol, and 40 single-nucleotide polymorphisms for triglycerides improved the prediction of adult dyslipidemia compared with clinical childhood risk factors. Adjusting for age, sex, body mass index, physical activity, and smoking in childhood, childhood lipid levels, and weighted genetic risk scores were associated with an increased risk of adult dyslipidemia for all lipids. Risk assessment based on 2 childhood lipid measures and the lipid-specific weighted genetic risk scores improved the accuracy of predicting adult dyslipidemia compared with the approach using only childhood lipid measures for low-density lipoprotein cholesterol (area under the receiver-operating characteristic curve 0.806 versus 0.811; P =0.01) and triglycerides (area under the receiver-operating characteristic curve 0.740 versus area under the receiver-operating characteristic curve 0.758; P <0.01). The overall net reclassification improvement and integrated discrimination improvement were significant for all outcomes. The inclusion of weighted genetic risk scores to lipid-screening programs in childhood could modestly improve the identification of those at highest risk of dyslipidemia in adulthood. © 2017 American Heart

The prevalence of dyslipidemia is rising alarmingly in elderly Han Chinese male patients with type 2 diabetes mellitus (T2DM). The genetic factors that contribute to the development of diabetic dyslipidemia remain incompletely identified. This study was conducted to assess the association between vitamin D receptor (VDR) polymorphisms and development of dyslipidemia in the Han elderly male population with T2DM in North China. A total of 242 T2DM patients with dyslipidemia (DH group, n=108) or without dyslipidemia (DO group, n=134) and 100 controls were genotyped for ApaI, TaqI and FokI single nucleotide polymorphisms (SNPs) of the VDR gene using polymerase chain reaction-restriction fragment length polymorphism and sequencing. The frequency and distribution of the SNPs were compared between cases and controls. The distribution of genotypes of VDR-FokI was significantly different between the control and DM group ( P =0.033), as well as between the control and DH subgroup ( P =0.011) but not DO subgroup ( P =0.111). The frequency of C allele and CC genotype of FokI was significantly higher in the DH patients than in the controls ( P =0.015 and P =0.003, respectively). Logistic regression analysis in a dominant model homozygous for the C allele of the FokI SNP showed that CC genotype was associated with DH patients (OR =1.797, 95% CI: 1.077-2.999, P =0.025). Significant associations of the ApaI and TaqI SNPs with either DO or DH subjects were not observed. These findings suggest that CC genotype of VDR-FokI is a risk factor for T2DM patients with dyslipidemia in elderly males in North China.

Fructose, insulin resistance, and metabolic dyslipidemia

Obesity and type 2 diabetes are occurring at epidemic rates in the United States and many parts of the world. The "obesity epidemic" appears to have emerged largely from changes in our diet and reduced physical activity. An important but not well-appreciated dietary change has been the substantial increase in the amount of dietary fructose consumption from high intake of sucrose and high fructose corn syrup, a common sweetener used in the food industry. A high flux of fructose to the liver, the main organ capable of metabolizing this simple carbohydrate, perturbs glucose metabolism and glucose uptake pathways, and leads to a significantly enhanced rate of de novo lipogenesis and triglyceride (TG) synthesis, driven by the high flux of glycerol and acyl portions of TG molecules from fructose catabolism. These metabolic disturbances appear to underlie the induction of insulin resistance commonly observed with high fructose feeding in both humans and animal models. Fructose-induced insulin resistant states are commonly characterized by a profound metabolic dyslipidemia, which appears to result from hepatic and intestinal overproduction of atherogenic lipoprotein particles. Thus, emerging evidence from recent epidemiological and biochemical studies clearly suggests that the high dietary intake of fructose has rapidly become an important causative factor in the development of the metabolic syndrome. There is an urgent need for increased public awareness of the risks associated with high fructose consumption and greater efforts should be made to curb the supplementation of packaged foods with high fructose additives. The present review will discuss the trends in fructose consumption, the metabolic consequences of increased fructose intake, and the molecular mechanisms leading to fructose-induced lipogenesis, insulin resistance and metabolic dyslipidemia.

Dyslipidemias represent a spectrum of lipid disorders that are important risk factors for cardiovascular disease. In addition, elevated triglycerides are known to be associated with pancreatitis. Though less clear, it is possible that dyslipidemias may also contribute to risk for venous thromboembolism (VTE). Ethinyl estradiol and progestogen, contained within combined hormonal contraception, are known to impact lipid metabolism. To evaluate from the literature whether use of combined hormonal contraception (CHC), including combined oral contraception (COC) pills, transdermal patch, vaginal ring or injectables, modifies the relative risk of acute myocardial infarction (MI), stroke, VTE or pancreatitis among women with known dyslipidemias and to determine if existing lipid abnormalities worsen with CHC use. PubMed and the Cochrane Library databases were searched for all articles in all languages published between inception and September 2014 relevant to dyslipidemia, CHC use and serious adverse events (MI, stroke, VTE or pancreatitis). The quality of each individual study was assessed using the system for grading evidence developed by the United States Preventive Services Task Force. From 306 articles identified by our search strategy, 3 articles met inclusion criteria. In a poor-quality case-control study, women with hypercholesterolemia but no COC use had an increased risk of MI (adjusted odds ratio [adj OR] 3.3, 95% confidence interval [CI] 1.6-6.8), as did women who used COCs but did not have hypercholesterolemia (adj OR 2.0, 95% CI 1.4-2.8), compared with non-COC users without hypercholesterolemia; women with both COC use and hypercholesterolemia had an adjusted OR of 24.7 (95% CI 5.6-108.5) compared with women with neither risk factor. A poor-quality cohort study examined COC users and reported that women with dyslipidemia had increased risk for VTE [crude risk ratio (RR) 1.39, 95% CI 1.04-1.85] and transient ischemic attacks or cerebrovascular accidents (CVAs

Insulin resistance plays a central role in the development of the metabolic syndrome, but how it relates to cardiovascular disease remains controversial. Liver insulin receptor knockout (LIRKO) mice have pure hepatic insulin resistance. On a chow diet, LIRKO mice have a proatherogenic lipoprotein profile with reduced HDL cholesterol and VLDL particles that are markedly enriched in cholesterol. This is due to increased secretion and decreased clearance of apoB-containing lipoproteins, coupled with decreased triglyceride secretion secondary to increased expression of PGC-1β, which promotes VLDL secretion, but decreased expression of SREBP-1c, SREBP-2 and their targets, the lipogenic enzymes and the LDL receptor. Within twelve weeks on an atherogenic diet, LIRKO mice show marked hypercholesterolemia, and 100% of LIRKO mice, but 0% of controls, develop severe atherosclerosis. Thus, insulin resistance at the level of the liver is sufficient to produce the dyslipidemia and increased risk of atherosclerosis associated with the metabolic syndrome. PMID:18249172

Cholesterol efflux capacities (CECs) are negatively associated with cardiovascular disease risk, irrespective of plasma high-density lipoprotein (HDL) cholesterol levels. Whether interventions targeting lifestyle improve HDL-CECs is unknown. Our objective was to determine whether improving dietary quality and increasing physical activity levels improves HDL-CECs in abdominally obese men with dyslipidemia. Our study sample included men (488.5 years) with an elevated waist circumference ({greater than or equal to}90 cm) associated with dyslipidemia (triglycerides {greater than or equal to}1.69 and/or HDL cholesterol <1.03 mmol/l); 113 men completed a 1-year intervention, consisting of a healthy eating and physical activity/exercise program and 32 were included in a control group. An oral lipid tolerance test (OLTT) was performed in a subsample of 28 men who completed the intervention and blood was collected every 2 hours during 8 hours. HDL-CECs were measured using 3 H cholesterol labeled J774 macrophages and HepG2 hepatocytes. The lifestyle modification program led to an overall improvement in the cardiometabolic risk profile, increases in J774-HDL-CEC by 14.1% (+0.881.09%, p<0.0001), HepG2-HDL-CEC by 3.4% (+0.170.75%, p=0.01), HDL-C and apolipoprotein A-1 levels (13.5%, p<0.0001 and 14.9%, p<0.0001, respectively). J774-HDL-CECs and HepG2-HDL-CECs did not change in the control group. The best predictor for changes in HDL-CEC was Apo A1 level. The lifestyle modification program also improved HDL-CECs response in postprandial lipemia during an OLTT. HDL-CEC did not change during the OLTT. Our results suggest that increasing physical activity levels and improving diet quality can have a positive impact on both HDL quantity and quality in abdominally obese men with dyslipidemia.

Sedentary overweight or obese adult (age<60 years) women, allocated in type 2 diabetes mellitus (T2DM, n =13), dyslipidemia alone (DYS, n =12), dyslipidemia associated with hyperglycaemia (DYSHG, N=12), or healthy control (CON, n =10) groups, had their lipid, glucose, blood pressure, endurance performance, and anthropometry variables assessed before and after 16 weeks of a thrice-weekly high-intensity interval training (HIIT) program. Triglycerides reduced significantly ( P <0.05) in all groups, and high-density lipoprotein increased ( P <0.01) in T2DM, DYS and DYSHG; however, low-density lipoprotein reduced ( P <0.05) only in DYSHG, and total cholesterol reduced ( P <0.01) only in DYS and DYSHG. Fasting glucose reduced ( P <0.05) significantly in T2DM, DYS and DYSHG, but with higher decreases in T2DM and DYSHG. Blood pressure, endurance performance and body composition improved ( P <0.05) in all groups. The HIIT program was effective for restoring lipid profile of DYS and DYSHG, and fasting glucose of DYSHG to levels similar to those of CON, with a weekly time commitment 25% to 56% lower than the minimum recommended in current exercise guidelines. These findings suggest that HIIT may be a time-efficient intervention for counteracting dyslipidemia. © Georg Thieme Verlag KG Stuttgart · New York.

Abnormal serum lipid levels significantly increase the risk for cardiovascular disease. Furthermore, abnormal compositions of cholesterol in glandular secretions have been hypothesized as an etiology for meibomian gland dysfunction, yet this relationship has not been well studied in clinical settings. The primary purpose of this study was to determine if there is an association between dyslipidemia and meibomian gland dysfunction (MGD). The secondary purpose was to identify the factors, if any, that play a role in this association. A case-control study was performed between October 2013 and February 2015 which recruited 109 patients with MGD and 115 control patients without MGD. All participants were of Indian descent and had no history of dyslipidemia. Basic demographic information was collected as well as fasting levels of serum glucose, creatinine, triglycerides, total cholesterol, low-density lipoprotein (LDL), and high-density lipoprotein (HDL). To calculate differences between groups, Z test or Student t test were used. A stepwise logistic regression model was used to calculate the estimates of odds ratios (ORs), where MGD was the dependent variable, making the independent variables consist of sex, age, body mass index (BMI), triglycerides ≥150 mg/dL, total cholesterol ≥200 mg/dL, LDL ≥130 mg/dL, or HDL ≤40 mg/dL, serum glucose, and serum creatinine. Dyslipidemia, defined by either a fasting total cholesterol level of ≥ 200 mg/dL, triglycerides ≥150 mg/dL, LDL ≥130 mg/dL, or HDL ≤40 mg/dL, was detected in 70 cases (64 %) and 21 controls (18 %), P < 0.001. Mean levels of triglycerides, total cholesterol, LDL, and HDL were 98.5 ± 42.1, 203.1 ± 13.2, 126.1 ± 10.2, and 53.3 ± 4.2 mg/dL, respectively, in cases and 82.3 ± 36.5, 156.6 ± 14.5, 92.2 ± 12.4, 45.8 ± 2.6 mg/dL, respectively, in controls. All differences were statistically significant (P < 0.05). MGD was significantly associated with age >65�

It has been suggested that serum branched-chain amino acids (BCAAs) are associated with the incident, progression and prognostic of type 2 diabetes. However, the role of BCAAs in metabolic dyslipidemia (raised triglycerides (TG) and reduced high-density lipoprotein cholesterol (HDL-C)) remains poorly understood. This study aims to investigate 1) the association of serum BCAAs with total cholesterol (TC), TG, HDL-C and low-density lipoprotein cholesterol (LDL-C) and 2) the association between serum BCAAs levels and risk of metabolic dyslipidemia in a community population with different glucose homeostasis. Demographics data and blood samples were collected from 2251 Chinese subjects from the Huaian Diabetes Protective Program (HADPP) study. After exclusion for cardiovascular disease (CVD), serious hepatic or nephritic diseases and others, 1320 subjects remained for analysis (789 subjects with hemoglobin A1c (HbA1c) > 5.7, 521 with HbA1c ≤ 5.7). Serum BCAAs level was measured by liquid chromatography-tandem mass spectrometry (LC MS/MS). The association of BCAAs with lipids or with the risk of metabolic dyslipidemia was analyzed. Elevated serum BCAAs (both total and individual BCAA) were positively associated with TG and inversely associated with HDL-C in the whole population. These correlations were still significant even after adjustment for confounding factors (r = 0.165, p < 0.001 for TG; and r = -0.126, p < 0.001 for HDL-C). For reduced HDL-C, we found higher odds risk (OR) of Valine (Val) in high HbA1c group than in the low one (OR = 1.055, p < 0.001 vs OR = 1.032, p = 0.059). Compared with that in the first quartile, the multivariable-adjusted OR (95 % CI) of the 4(th) quartile of serum total BCAAs level for reduced HDL-C was 3.689 (2.325, 5.854) in high HbA1c group and 2.329 (1.284, 4.227) in low group, for raised TG was 3.305 (2.120, 5.152) and 2.972 (1.706, 5.176), and for metabolic dyslipidemia was 3.703 (2.261, 6

HIV-1 infected individuals have an increased cardiovascular risk which is partially mediated by dyslipidemia. Single nucleotide polymorphisms in multiple genes involved in lipid transport and metabolism are presumed to modulate the risk of dyslipidemia in response to antiretroviral therapy. The contribution to dyslipidemia of 20 selected single nucleotide polymorphisms of 13 genes reported in the literature to be associated with plasma lipid levels (ABCA1, ADRB2, APOA5, APOC3, APOE, CETP, LIPC, LIPG, LPL, MDR1, MTP, SCARB1, and TNF) was assessed by longitudinally modeling more than 4400 plasma lipid determinations in 438 antiretroviral therapy-treated participants during a median period of 4.8 years. An exploratory genetic score was tested that takes into account the cumulative contribution of multiple gene variants to plasma lipids. Variants of ABCA1, APOA5, APOC3, APOE, and CETP contributed to plasma triglyceride levels, particularly in the setting of ritonavir-containing antiretroviral therapy. Variants of APOA5 and CETP contributed to high-density lipoprotein-cholesterol levels. Variants of CETP and LIPG contributed to non-high-density lipoprotein-cholesterol levels, a finding not reported previously. Sustained hypertriglyceridemia and low high-density lipoprotein-cholesterol during the study period was significantly associated with the genetic score. Single nucleotide polymorphisms of ABCA1, APOA5, APOC3, APOE, and CETP contribute to plasma triglyceride and high-density lipoprotein-cholesterol levels during antiretroviral therapy exposure. Genetic profiling may contribute to the identification of patients at risk for antiretroviral therapy-related dyslipidemia.

Low-density lipoprotein cholesterol (LDL-C) is a major contributor to cardiovascular disease. In the Dyslipidemia International Study II (DYSIS II), we determined LDL-C target value attainment, use of lipid-lowering therapy (LLT), and cardiovascular outcomes in patients with stable coronary heart disease (CHD) and those suffering from an acute coronary syndrome (ACS). DYSIS II included patients from 18 countries. Patients with either stable CHD or an ACS were enrolled if they were ≥18 years old and had a full lipid profile available. Data were collected at a physician visit (CHD cohort) or at hospital admission and 120 days later (ACS cohort). A total of 10,661 patients were enrolled, 6794 with stable CHD and 3867 with an ACS. Mean LDL-C levels were low at 88 mg/dl and 108 mg/dl for the CHD and ACS cohorts respectively, with only 29.4% and 18.9% displaying a level below 70 mg/dl. LLT was utilized by 93.8% of the CHD cohort, with a mean daily statin dosage of 25 ± 18 mg. The proportion of the ACS cohort treated with LLT rose from 65.2% at admission to 95.6% at follow-up. LLT-treated patients, who were female, obese, or current smokers, were less likely to achieve an LDL-C level of <70 mg/dl, while those with type 2 diabetes, chronic kidney disease, or those taking a higher statin dosage were more likely. Few of these very high-risk patients achieved the LDL-C target, indicating huge potential for improving cardiovascular outcome by use of more intensive LLT. Copyright © 2017.

Fibrates are an essential part of modern anti-dyslipidemic arsenal: spotlight on atherogenic dyslipidemia and residual risk reduction.

Currently the world faces epidemic of several closely related conditions: obesity, metabolic syndrome and type 2 diabetes (T2DM). The lipid profile of these patients and those with metabolic syndrome is characterized by the concurrent presence of qualitative as well as quantitative lipoprotein abnormalities: low levels of HDL, increased triglycerides, and prevalence of LDL particles that are smaller and denser than normal. This lipid phenotype has been defined as atherogenic dyslipidemia. Overwhelming evidences demonstrate that all components of the atherogenic dyslipidemia are important risk-factors for cardiovascular diseases. Optimal reduction of cardiovascular risk through comprehensive management of atherogenic dyslipidemias basically depends of the presence of efficacious lipid-modulating agents (beyond statin-based reduction of LDL-C). The most important class of medications which can be effectively used nowadays to combat atherogenic dyslipidemias is the fibrates. From a clinical point of view, in all available 5 randomized control trials beneficial effects of major fibrates (gemfibrozil, fenofibrate, bezafibrate) were clearly demonstrated and were highly significant in patients with atherogenic dyslipidemia. In these circumstances, the main determinant of the overall results of the trial is mainly dependent of the number of the included appropriate patients with atherogenic dyslipidemia. In a meta-analysis of dyslipidemic subgroups totaling 4726 patients a significant 35% relative risk reduction in cardiovascular events was observed compared with a non significant 6% reduction in those without dyslipidemia. However, different fibrates may have a somewhat different spectrum of effects. Currently only fenofibrate was investigated and proved to be effective in reducing microvascular complications of diabetes. Bezafibrate reduced the severity of intermittent claudication. Cardinal differences between bezafibrate and other fibrates are related to the effects on

This lipid phenotype has been defined as atherogenic dyslipidemia. Overwhelming evidences demonstrate that all components of the atherogenic dyslipidemia are important risk-factors for cardiovascular diseases. Optimal reduction of cardiovascular risk through comprehensive management of atherogenic dyslipidemias basically depends of the presence of efficacious lipid-modulating agents (beyond statin-based reduction of LDL-C). The most important class of medications which can be effectively used nowadays to combat atherogenic dyslipidemias is the fibrates. From a clinical point of view, in all available 5 randomized control trials beneficial effects of major fibrates (gemfibrozil, fenofibrate, bezafibrate) were clearly demonstrated and were highly significant in patients with atherogenic dyslipidemia. In these circumstances, the main determinant of the overall results of the trial is mainly dependent of the number of the included appropriate patients with atherogenic dyslipidemia. In a meta-analysis of dyslipidemic subgroups totaling 4726 patients a significant 35% relative risk reduction in cardiovascular events was observed compared with a non significant 6% reduction in those without dyslipidemia. However, different fibrates may have a somewhat different spectrum of effects. Currently only fenofibrate was investigated and proved to be effective in reducing microvascular complications of diabetes. Bezafibrate reduced the severity of intermittent claudication. Cardinal differences between bezafibrate and other fibrates are related to the effects on

Proprotein convertase subtilisin/kexin type-9 (PCSK9) is a secreted zymogen expressed primarily in the liver. PCSK9 circulates in plasma, binds to cell surface low-density lipoprotein (LDL) receptors, is internalized, and then targets the receptors to lysosomal degradation. Studies of naturally occurring PCSK9 gene variants that caused extreme plasma LDL cholesterol (LDL-C) deviations and altered atherosclerosis risk unleashed a torrent of biological and pharmacological research. Rapid progress in understanding the physiological regulation of PCSK9 was soon translated into commercially available biological inhibitors of PCSK9 that reduced LDL-C levels and likely also cardiovascular outcomes. Here we review the swift evolution of PCSK9 from novel gene to drug target, to animal and human testing, and finally to outcome trials and clinical applications. In addition, we explore how the genetics-guided path to PCSK9 inhibitor development exemplifies a new paradigm in pharmacology. Finally, we consider some potential challenges as PCSK9 inhibition becomes established in the clinic.

We determined the alleles of ten single nucleotide poly-morphisms (SNPs) in the APOA5/A4/C3/A1 gene cluster and in APOB in Han Chinese from Xinjiang Shihezi, China using MALDI-TOF mass spectrometry, and explored the correlation between these SNPs and dyslipidemia through a case-control study design with 250 pa-tients and 250 normal controls. All SNPs except for APOA5 rs2072560 conformed to Hardy-Weinberg equilibrium (all P > 0.05). APOA5 rs651821, APOA4 rs5104, APOC3 rs734104, and APOC3 rs5128 geno-type and allele frequencies were significantly different between groups (all P < 0.01). For rs651821, the risks of dyslipidemia for the CC or CC+CT genotypes were 9.917 or 1.859 times that of TT, and the risk of the C vs T allele was 2.027. For rs5104, the AG, GG, or AG+GG risks were 1.797, 1.861, and 1.809 times AA, and the G vs A risk was 1.427. For rs734104, the CT, CC, or CC+CT risks were 1.851, 2.570, and 1.958 times TT, and the C vs T risk was 1.610. For rs5128, the GC or CC+GC risks were 1.738 or 1.749 times GG, and the C vs G risk was 1.477. Compared with the wild-type haplotype TATG, the risks of dyslipidemia with CGCC, TGCC, or CATG haplotypes (odds ratios = 2.434, 1.503, and 2.740, respectively) were significantly higher. Our results suggested that these four SNPs were significantly associated with dyslipidemia in Xinjiang Shihezi Han Chinese, and might serve as risk factors for dyslipidemia. Individuals carrying the CGCC, TGCC, or CATG haplotypes were prone to dyslipidemia.

Strategies for the effective management of cardiovascular risk factors in patients with the metabolic syndrome (MS) or type 2 diabetes mellitus (T2DM) are essential to help reduce cardiovascular morbidity and mortality. Treatment strategies should be multi-factorial and include the promotion of therapeutic lifestyle changes, as well as pharmacologic therapies to treat individual risk factors according to current guidelines. In an accompanying article, the importance of atherogenic dyslipidemia as a risk factor for the development of cardiovascular disease in patients with the MS or T2DM was highlighted. Current treatment options for managing this characteristic form of atherogenic dyslipidemia are limited and tend to be only moderately effective. The focus of this review is the current pharmacotherapies available for the management of atherogenic dyslipidemia in patients with the MS or T2DM, highlighting the rationale for combining available treatments. Novel strategies currently in clinical development are also discussed. PMID:19751468

To evaluate the efficacy of liraglutide with pioglitazone for prevention of dexamethasone induced hepatic steatosis, dyslipidemia and hyperglycemia in Albino rats. There were four groups of six rats each. First group received dexamethasone alone in a dose of 8 mg/kg intraperitoneally for 6 days to induce metabolic changes and considered as dexamethasone control. Second group received liraglutide 1.8 mg/kg subcutaneously 6 days before dexamethasone and 6 days during dexamethasone administration. Third group received pioglitazone 45 mg/kg orally 6 days before dexamethasone and 6 days during dexamethasone administration. Fourth group did not receive any medication and was considered as normal control. Fasting blood sugar, lipid profile, blood sugar 2 h after glucose load were measured. Liver weight, liver volume, and histopathological analysis were done. Dexamethasone caused hepatomegaly, dyslipidemia, and hyperglycemia. Both pioglitazone and liraglutide significantly reduced hepatomegaly, dyslipidemia and hyperglycemia (P < 0.01). Reduction of blood sugar levels after glucose load was significant with pioglitazone when compared with liraglutide (P < 0.01). Liraglutide has comparable efficacy to pioglitazone in prevention of dexamethasone induced hepatomegaly, dyslipidemia and fasting hyperglycemia.

To investigate whether atherogenic dyslipidemia, a dyslipidemic profile combining elevated triglycerides and low high-density lipoprotein (HDL) cholesterol, is predictive of risk of silent myocardial ischemia (SMI) or angiographic coronary artery disease (CAD) in asymptomatic patients with type 2 diabetes. Cohort study in 1080 asymptomatic patients with type 2 diabetes with a normal resting electrocardiogram, at least one additional cardiovascular risk factor and low density lipoprotein (LDL) cholesterol <3.35 mmol/L. Patients initially underwent screening for SMI by stress myocardial scintigraphy. Patients with SMI underwent coronary angiography. Overall, 60 (5.5 %) patients had atherogenic dyslipidemia (triglycerides ≥2.26 mmol/L and HDL cholesterol ≤0.88 mmol/L). In multivariate analyses taking into account the parameters associated in univariate analyses with SMI and then CAD, atherogenic dyslipidemia was associated with SMI (odds ratio 1.8[1.0-3.3]), as were male gender (OR 2.1[1.5-2.9]), BMI (OR 0.97[0.94-0.997]), retinopathy (OR 1.4[1.1-1.9]), peripheral occlusive arterial disease (POAD: OR 2.5[1.6-3.8]) and mean blood pressure (OR 1.01[1.00-1.03]); atherogenic dyslipidemia was associated with CAD (OR 4.0[1.7-9.2]), as were male gender (OR 3.0[1.6-5.6]), BMI (OR 0.94[0.90-0.995]), retinopathy (OR 1.7[1.0-2.9], POAD (OR 4.0[2.1-7.4]) and mean blood pressure (OR 1.03[1.01-1.05]). In the subgroup of 584 patients with LDL cholesterol <2.6 mmol/L, atherogenic dyslipidemia was also associated with CAD (OR 3.6[1.5-9.0]). Atherogenic dyslipidemia was associated with an increased risk of SMI and silent CAD in patients with type 2 diabetes and LDL cholesterol levels <3.35 mmol/L. Specific management of atherogenic dyslipidemia might help reducing the high residual burden of cardiovascular disease.

The risk factors for ischemic heart disease (IHD) or cerebrovascular accident (CVA) in elderly diabetic individuals with type IIb dyslipidemia are not fully known. Therefore, we investigated the relationship between lipid levels and IHD and CVA in diabetic individuals with type IIb dyslipidemia. The Japan Cholesterol and Diabetes Mellitus Study is a prospective cohort study of 4014 type 2 diabetic patients (1936 women; age 67.4 ± 9.5 years). The primary end-points were the onset of IHD or CVA. Lipid and glucose levels, and other factors were investigated in relation to the occurrence of IHD or CVA. A total of 462 participants were included in the group of patients with type IIb dyslipidemia. The 462 diabetic participants with type IIb dyslipidemia were divided into those who were aged <65 years, 65-74 years and >75 years (n=168, 190 and 104, respectively). High-density lipoprotein cholesterol (HDL-C) and low-density lipoprotein cholesterol/HDL-C were significantly associated with the risk of cardiovascular events in diabetic individuals with type IIb dyslipidemia who were aged <65 years, and HDL-C and diastolic blood pressure was significantly associated with cardiovascular events in patients aged 65-74 years. Non-HDL-C was not significantly associated with the risk of cardiovascular events. Multiple regression analysis showed that lower HDL-C was significantly associated with the risk of cardiovascular events in diabetic individuals with type IIb dyslipidemia who were aged <65 years and 65-74 years. Lower HDL-C was an important risk factor for cardiovascular events in diabetic individuals with type IIb dyslipidemia who were aged <75 years. © 2013 Japan Geriatrics Society.

Low levels of food security are associated with dyslipidemia and chronic disease in adults, particularly in women. There is a gap in knowledge about the relationship between food security among youth and dyslipidemia and chronic disease. We investigated the relationship between food security status and dyslipidemia among low-income adolescents. We analyzed data from adolescents aged 12 to 18 years (N = 1,072) from households with incomes at or below 200% of the federal poverty level from the National Health and Nutrition Examination Survey (NHANES) 2003-2010. We used logistic regression to examine the relationship between household food security status and the odds of having abnormalities with fasting total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), serum triglycerides (TGs), high-density lipoprotein cholesterol (HDL-C), TG/HDL-C ratio, and apolipoprotein B (Apo B). Models included age, sex, race/ethnicity, smoking status, partnered status in the household, and maternal education, with additional adjustment for adiposity. Household food security status was not associated with elevated TC or LDL-C. Adolescents with marginal food security were more likely than food-secure peers to have elevated TGs (odds ratio [OR] = 1.86; 95% confidence interval [CI], 1.14-3.05), TG/HDL-C ratio (OR = 1.74; 95% CI, 1.11-2.82), and Apo B (OR = 1.98; 95% CI, 1.17-3.36). Female adolescents with marginal food security had greater odds than male adolescents of having low HDL-C (OR = 2.69; 95% CI, 1.14-6.37). No elevated odds of dyslipidemia were found for adolescents with low or very low food security. Adjustment for adiposity did not attenuate estimates. In this nationally representative sample, low-income adolescents living in households with marginal food security had increased odds of having a pattern consistent with atherogenic dyslipidemia, which represents a cardiometabolic burden above their risk from adiposity alone.

Obstructive sleep apnea (OSA) is independently associated with dyslipidemia. Previous studies have demonstrated that sleep fragmentation can impair lipid metabolism. The present study aimed to identify whether sleep fragmentation is independently associated with dyslipidemia, in a large-scale, clinic-based consecutive OSA sample. This cross-sectional study was conducted among 2,686 patients who underwent polysomnography (PSG) for suspicion of OSA from January 2008 to January 2013 at the sleep laboratory. Multivariate regression analyses were performed to evaluate the independent associations between the microarousal index (MAI) and lipid profiles adjusting for potential confounders, including metabolic syndrome components and nocturnal intermittent hypoxia. The adjusted odds ratios (ORs) for various types of dyslipidemia according to MAI quartiles, as determined by logistic regression were also evaluated. MAI was found positively associated with low-density lipoprotein cholesterol (LDL-c) but not with total cholesterol (TC), triglyceride (TG) or high-density lipoprotein cholesterol (HDL-c). Furthermore, the adjusted ORs (95% confidence interval) for hyper-LDL cholesterolemia increased across MAI quartiles, as follows: 1 (reference), 1.3 (1.1-1.7), 1.6 (1.2-2.0), and 1.6 (1.2-2.1) (p = 0.001, linear trend). Sleep fragmentation in OSA is independently associated with hyper-LDL cholesterolemia, which may predispose patients with OSA to a higher risk of cardiovascular disease.

The association between adiposity measures and dyslipidemia has seldom been assessed in a multipopulational setting. 27 populations from Europe, Australia, New Zealand and Canada (WHO MONICA project) using health surveys conducted between 1990 and 1997 in adults aged 35-64 years (n = 40,480). Dyslipidemia was defined as the total/HDL cholesterol ratio >6 (men) and >5 (women). Overall prevalence of dyslipidemia was 25% in men and 23% in women. Logistic regression showed that dyslipidemia was strongly associated with body mass index (BMI) in men and with waist circumference (WC) in women, after adjusting for region, age and smoking. Among normal-weight men and women (BMI<25 kg/m(2)), an increase in the odds for being dyslipidemic was observed between lowest and highest WC quartiles (OR = 3.6, p < 0.001). Among obese men (BMI ≥ 30), the corresponding increase was smaller (OR = 1.2, p = 0.036). A similar weakening was observed among women. Classification tree analysis was performed to assign subjects into classes of risk for dyslipidemia. BMI thresholds (25.4 and 29.2 kg/m(2)) in men and WC thresholds (81.7 and 92.6 cm) in women came out at first stages. High WC (>84.8 cm) in normal-weight men, menopause in women and regular smoking further defined subgroups at increased risk. standard categories of BMI and WC, or their combinations, do not lead to optimal risk stratification for dyslipidemia in middle-age adults. Sex-specific adaptations are necessary, in particular by taking into account abdominal obesity in normal-weight men, post-menopausal age in women and regular smoking in both sexes.

Dietary carbohydrates have been associated with dyslipidemia, a lipid profile known to increase cardiovascular disease risk. Added sugars (caloric sweeteners used as ingredients in processed or prepared foods) are an increasing and potentially modifiable component in the US diet. No known studies have examined the association between the consumption of added sugars and lipid measures. To assess the association between consumption of added sugars and blood lipid levels in US adults. Cross-sectional study among US adults (n = 6113) from the National Health and Nutrition Examination Survey (NHANES) 1999-2006. Respondents were grouped by intake of added sugars using limits specified in dietary recommendations (< 5% [reference group], 5%-<10%, 10%-<17.5%, 17.5%-<25%, and > or = 25% of total calories). Linear regression was used to estimate adjusted mean lipid levels. Logistic regression was used to determine adjusted odds ratios of dyslipidemia. Interactions between added sugars and sex were evaluated. Adjusted mean high-density lipoprotein cholesterol (HDL-C), geometric mean triglycerides, and mean low-density lipoprotein cholesterol (LDL-C) levels and adjusted odds ratios of dyslipidemia, including low HDL-C levels (< 40 mg/dL for men; < 50 mg/dL for women), high triglyceride levels (> or = 150 mg/dL), high LDL-C levels (> or = 130 mg/dL), or high ratio of triglycerides to HDL-C (> 3.8). Results were weighted to be representative of the US population. A mean of 15.8% of consumed calories was from added sugars. Among participants consuming less than 5%, 5% to less than 17.5%, 17.5% to less than 25%, and 25% or greater of total energy as added sugars, adjusted mean HDL-C levels were, respectively, 58.7, 57.5, 53.7, 51.0, and 47.7 mg/dL (P < .001 for linear trend), geometric mean triglyceride levels were 105, 102, 111, 113, and 114 mg/dL (P < .001 for linear trend), and LDL-C levels modified by sex were 116, 115, 118, 121, and 123 mg/dL among women (P = .047 for linear

Dyslipidemia in PCOS.

PubMed

Wild, Robert A

2012-03-10

Life-long apolipoprotein lipid metabolic dysfunction in women with PCOS exaggerates the risk for cardiovascular disease (CVD) with aging. The dysfunction has involved insulin resistance (IR), which occurs in most women with PCOS. Women with PCOS have androgen excess, IR, variable amounts of estrogen exposure, and many environmental factors, all of which can influence lipid metabolism. On average, women with PCOS were higher triglyceride [26.39 95% CI (17.24, 35.54)], lower HDL-cholesterol [6.41 95% CI (3.69, 9.14)], and higher non HDL cholesterol levels [18.82 95% CI (15.53, 22.11)] than their non-PCOS counterparts. They have higher ApoCIII/ApoCII ratios and higher ApoCI even if they are not obese. ApoC1 elevation in women with PCOS needs to be further evaluated as a marker of dysfunction and potential CVD risk. ApoB measurements track with non-HDL cholesterol as a surrogate for increased atherogenic circulating small LDL particles. Elevated triglycerides and waist circumference predict CVD risk and women with PCOS often have these phenotypes. Diet and exercise interventions followed by selective lipid lowering medications are encouraged to normalize the dyslipidemia. Copyright © 2012 Elsevier Inc. All rights reserved.

To explore the associations between the Chinese famine exposure in early life and the dyslipidemia in adulthood. We selected 2752 participants from the baseline survey of China Health and Retirement Longitudinal Study (CHARLS) 2011-2012 to evaluate the associations of early life the Chinese famine exposure with risk of dyslipidemia in adulthood. Dyslipidemia was defined as TC (Total Cholesterol): HDL-C (High-Density Lipoprotein Cholesterol) ratio ≥ 5.0 or use cholesterol lowering drugs. Famine exposure cohorts were categorized by birthdates of participants. Binary logistics regression model was used to examine the associations of early-life famine exposure with the risk of dyslipidemia. The dyslipidemia prevalence of the non-exposed cohort, fetal stage-, infant stage-, and preschool stage-exposed cohorts in adulthood was 15.7%, 23.1%, 22.0%, and 18.6%, respectively. Early-life exposure to the Chinese famine significantly increased LDL cholesterol concentrations in adulthood after adjusted for age. The risks of dyslipidemia in fetal (OR = 1.58; 95% CI: 1.23-2.03; P < 0.001) and infant (OR = 1.52; 95% CI: 1.15-2.00; P = 0.003) stage-exposed cohorts were significantly higher than the non-exposed cohort after adjusted for gender and current family economic status. Following gender stratification, we found that fetal (OR = 1.80; 95% CI: 1.26-2.57; P = 0.001), infant (OR = 1.75; 95% CI: 1.17-2.62; P = 0.006), and preschool (OR = 1.63; 95% CI: 1.10-2.42; P = 0.015) -stage exposure to severe famine aggravated the risk of dyslipidemia in female adults. However, the similar association was not observed for male adults. Early-life exposure to severe Chinese famine could link with the higher dyslipidemia risk in female adulthood, but not in male adulthood. This gender-specific effect might be associated with the hypothesis that parents in China prefer boys to girls traditionally or survivors' bias.

Microbial translocation has been suggested to be a driver of immune activation and inflammation. It is hypothesized that microbial translocation may be related to dyslipidemia, insulin resistance, and the risk of coronary heart disease in HIV-infected individuals. Cross-sectional study of 60 HIV-infected patients on combination antiretroviral therapy with viral suppression >2 years and 31 healthy age-matched controls. Lipopolysaccharide (LPS) was analyzed by limulus amebocyte lysate colorimetric assay. Lipids, including cholesterol, low-density lipoprotein (LDL), and triglycerides, were measured. Glucose metabolism was determined using an oral glucose tolerance test. Body composition was determined using whole-body dual-energy x-ray absorptiometry scans and magnetic resonance imaging. The Framingham risk score was used to assess risk of cardiovascular disease and myocardial infarction. HIV-infected patients had higher level of LPS compared with controls (64 pg/mL vs. 50 pg/mL, P = 0.002). Likewise, HIV-infected patients had higher triglycerides, LDL, and fasting insulin as well as evidence of lower insulin sensitivity compared with controls. Among HIV-infected patients, high LPS was associated with a higher level of triglycerides and LDL and with lower insulin sensitivity. Importantly, among HIV-infected patients, high LPS was associated with a higher Framingham risk score. HIV-infected patients with suppressed viral replication had increased level of microbial translocation as measured by LPS. LPS was associated with cardiometabolic risk factors and increased Framingham risk score. Hence, the gastrointestinal mucosal barrier may be a potential therapeutic target to prevent dyslipidemia and future cardiovascular complications in HIV infection.

Despite the continuous improvement of the quality of lipid lowering therapy the achievement of target values is still not satisfactory, mainly in the very high cardiovascular risk category patients, where the goal of low density lipoprotein cholesterol (LDL-C) is 1.80 mmol/l. The trends in lipid lowering treatment of 17420 patients from different studies conducted between 2004 and 2010 were compared to that of 1626 patients of MULTI GAP (MULTI Goal Attainment Problem) 2011 treated by general practitioners (GPs) and specialists. In MULTI GAP 2011 the mean LDL-C level ± SD) of patients treated by GPs was found to be 2.87 ±1.01 mmol/l, the target value of 2.50 was achieved by 40% of them, in the specialists' patients the mean LDL-C level proved to be 2.77 ±1.10 mmol/l and the achievement rate was 45%. In the 2.50 mmol/l achievement rate of GPs' patients a satisfactory improvement was observed in the studied years, but the 1.80 mmol/l LDL-C goal in 2011 was attained only in 11% of very high risk cases. There was a linear correlation between the patient compliance estimated by the physicians and the LDL-C achievement rate. As the number of very high risk category patients has been increased according to the new European dyslipidemia guidelines, growing attention needs to be placed on attainment of the 1.80 mmol/l LDL-C level. Based on the results of the MULTI GAP studies, improving patients' adherence and the continuous training of physicians are necessary.

Atherogenic dyslipidemia is associated with poor cardiovascular outcomes, yet markers of this condition are often ignored in clinical practice. Here, we address a clear evidence gap by assessing the prevalence and treatment of two markers of atherogenic dyslipidemia: elevated triglyceride levels and low levels of high-density lipoprotein cholesterol. This cross-sectional observational study assessed the prevalence of two atherogenic dyslipidemia markers, high triglyceride levels and low high-density lipoprotein cholesterol levels, in the study population from the European Study on Cardiovascular Risk Prevention and Management in Usual Daily Practice (EURIKA; N = 7641; of whom 51.6% were female and 95.6% were White/Caucasian). The EURIKA population included European patients, aged at least 50 years with at least one cardiovascular risk factor but no history of cardiovascular disease. Over 20% of patients from the EURIKA population have either triglyceride or high-density lipoprotein cholesterol levels characteristic of atherogenic dyslipidemia. Furthermore, the proportions of patients with one of these markers were higher in subpopulations with type 2 diabetes mellitus or those already calculated to be at high risk of cardiovascular disease. Approximately 55% of the EURIKA population who have markers of atherogenic dyslipidemia are not receiving lipid-lowering therapy. A considerable proportion of patients with at least one major cardiovascular risk factor in the primary cardiovascular disease prevention setting have markers of atherogenic dyslipidemia. The majority of these patients are not receiving optimal treatment, as specified in international guidelines, and thus their risk of developing cardiovascular disease is possibly underestimated. The present study is registered with ClinicalTrials.gov (ID: NCT00882336).

Adipocyte Triglyceride Turnover Is Independently Associated With Atherogenic Dyslipidemia

Background Inappropriate storage of fatty acids as triglycerides in adipocytes and their removal from adipocytes through lipolysis and subsequent oxidation may cause the atherogenic dyslipidemia phenotype of elevated apolipoprotein B levels and subsequent hypertriglyceridemia. We tested whether turnover of triglycerides in fat cells was related to dyslipidemia. Methods and Results The age of triglycerides (reflecting removal) and triglyceride storage in adipocytes was determined under free living conditions by measuring incorporation of atmospheric 14C into these lipids within the adipocytes in 47 women and 26 men with a large interindividual variability in body mass index. Because limited 14C data were available, triglyceride age was also determined in 97 men and 233 women by using an algorithm based on adipocyte lipolysis, body fat content, waist‐to‐hip ratio, and insulin sensitivity. This cohort consisted of nonobese subjects since obesity per se is related to all components in the algorithm. Triglyceride turnover (age and storage) was compared with plasma levels of apolipoproteins and lipids. Plasma levels of apolipoprotein B and triglycerides were positively related to triglyceride age in adipocytes, when measured directly using radiocarbon analyses (r=0.45 to 0.47; P<0.0001). This effect was independent of subject age, waist circumference measures, and insulin sensitivity (partial r=0.29 to 0.45; P from 0.03 to <0.0001). Triglyceride storage showed no independent correlation (partial r=0.02 to 0.11; P=0.42 to 0.91). Algorithm‐based values for adipocyte removal of triglycerides were positively associated with plasma triglycerides and apolipoprotein B (r=0.44 to 0.45; P<0.0001) and (also positively) with the inflammation status of adipose tissue (r=0.39 to 0.47; P<0.05). These correlations were statistically independent of subject age and observed in men and women as well as in lean and overweight subjects when subgroups were examined separately

Lipid metabolism disorders (dyslipidemia) are causes of male infertility, but little is known about their impact on male gametes when considering post-testicular maturation events, given that studies concentrate most often on endocrine dysfunctions and testicular consequences. In this study, three-month-old wild-type ( wt ) and Liver-X-Receptors knock out ( Lxrα;β - / - ) males were fed four weeks with a control or a lipid-enriched diet containing 1.25% cholesterol (high cholesterol diet (HCD)). The HCD triggered a dyslipidemia leading to sperm post-testicular alterations and infertility. Sperm lipids were analyzed by LC-MS and those from Lxrα;β - / - males fed the HCD showed higher chol/PL and PC/PE ratios compared to wt -HCD ( P  < 0.05) and lower oxysterol contents compared to wt ( P  < 0.05) or Lxrα;β - / - ( P  < 0.05). These modifications impaired membrane-associated events triggering the tyrosine phosphorylation normally occurring during the capacitation process, as shown by phosphotyrosine Western blots. Using flow cytometry, we showed that a smaller subpopulation of spermatozoa from Lxrα;β - / - -HCD males could raise their membrane fluidity during capacitation ( P  < 0.05 vs wt or wt-HCD ) as well as their intracellular calcium concentration ( P  < 0.05 vs Lxrα;β - / - and P  < 0.001 vs wt ). The accumulation of the major sperm calcium efflux pump (PMCA4) was decreased in Lxrα;β - / - males fed the HCD ( P  < 0.05 vs Lxrα;β - / - and P  < 0.001 vs wt ). This study is the first showing an impact of dyslipidemia on post-testicular sperm maturation with consequences on the capacitation signaling cascade. It may lead to the identification of fertility prognostic markers in this pathophysiological situation, which could help clinicians to better understand male infertilities which are thus far classified as idiopathic. © 2017 Society for Reproduction and Fertility.

The 2013 American College of Cardiology/American Heart Association guidelines on cholesterol management placed greater emphasis on statin therapy given the well-established benefits in primary and secondary prevention of cardiovascular disease. Residual risk may remain after statin initiation, in part because of triglyceride-rich lipoprotein cholesterol. Several large trials have failed to show benefit with non-statin cholesterol-lowering medications in the reduction of cardiovascular events. Yet, subgroup analyses showed a benefit in those with hypertriglyceridemia and lower high-density lipoprotein cholesterol level, a high-risk pattern of dyslipidemia. This review discusses the benefits of omega-3 carboxylic acids, a recently approved formulation of omega-3 fatty acid with enhanced bioavailability, in the treatment of dyslipidemia both as monotherapy and combination therapy with a statin.

To explore the rules of TCM syndrome in patients with dyslipidemia and its relation with C-reactive protein (CRP), homocysteine (Hcy), carotid ultrasonic picture, blood lipids and blood viscosity. From 152 recruited patients symptoms and physical signs (including figures of tongue and pulse) were selected and analyzed in grading and quantifying by factor analysis. At the same time, blood lipids, CRP, Hcy, carotid ultrasonic picture and blood viscosity were detected to conduct a canonical correlation analysis for exploring the relationship between different TCM syndromes and their corresponding physical and/or chemical indexes. Five types of TCM syndrome obtained by factor analysis were syndrome of Shen-yin deficiency (I), Pi-qi deficiency (II), turbid-phlegm impediment (III), blood stasis (IV), and phlegm-blood block (V). By canonical correlation analysis, they were characterized with: Type I, high levels of CRP and blood viscosity; Type II, high level of very low-density lipoprotein cholesterol (VLDL-C); Type III, high level of total cholesterol (TC) and low level of high-density lipoprotein cholesterol (HDL-C); and Type V, high level of Hcy. The five syndrome types frequently found in patients with dyslipidemia are syndrome of Shen-yin deficiency, Pi-qi deficiency, turbid-phlegm impediment, blood stasis, and phlegm-blood block. Different syndrome has its own correlation with some corresponding physical and/or chemical laboratory indexes, the issue provides new evidences for the objectification of TCM syndromes in patients with dyslipidemia.

Dyslipidemia is a major risk factor for cardiovascular disease (CVD), which is the leading cause of morbidity and mortality in type 2 diabetes (T2DM). Statins have played a crucial role in its management, but residual risk remains since many patients cannot achieve their desired low-density lipoprotein cholesterol (LDL-C) level and up to 20% of patients are statin-intolerant, experiencing adverse events perceived to be caused by statins, most commonly muscle symptoms. Recently, great advances have been made in nonstatin treatment with ezetimibe, a cholesterol absorption inhibitor, and proprotein convertase subtilisin/kexin type 9 (PCSK9) monoclonal antibodies (mAbs), all showing a proven benefit with an excellent safety profile in cardiovascular outcome trials. This review summarizes the key aspects and the evolving role of these agents in the management of dyslipidemia in patients with T2DM, along with a brief introduction of novel drugs currently in development.

Lipids are essential components of cell membranes, contributing to cell fuel, myelin formation, subcellular organelle function, and steroid hormone synthesis. Children with chronic kidney disease (CKD) and end-stage renal disease (ESRD) exhibit various co-morbidities, including dyslipidemia. The prevalence of dyslipidemias in children with CKD and ESRD is high, being present in 39-65% of patients. Elevated lipid levels in children without renal disease are a risk factor for cardiovascular disease (CVD), while the risk for CVD in pediatric CKD/ESRD is unclear. The pathogenesis of dyslipidemia in CKD features various factors, including increased levels of triglycerides, triglyceride-rich lipoproteins, apolipoprotein C3 (ApoC-III), decreased levels of cholesterylester transfer protein and high-density lipoproteins, and aberrations in serum very low-density and intermediate-density lipoproteins. If initial risk assessment indicates that a child with advanced CKD has 2 or more co-morbidities for CVD, first-line treatment should consist of non-pharmacologic management such as therapeutic lifestyle changes and dietary counseling. Pharmacologic treatment of dyslipidemia may reduce the incidence of CVD in children with CKD/ESRD, but randomized trials are lacking. Statins are the only class of lipid-lowering drugs currently approved by the U.S. Food and Drug Administration (FDA) for use in the pediatric population. FDA-approved pediatric labeling for these drugs is based on results from placebo-controlled trial results, showing 30-50% reductions in baseline low-density lipoprotein cholesterol. Although statins are generally well tolerated in adults, a spectrum of adverse events has been reported with their use in both the clinical trial and post-marketing settings.

Objective To explore whether red yeast rice is a safe and effective alternative approach for dyslipidemia. Methods Pubmed, the Cochrane Library, EBSCO host, Chinese VIP Information (VIP), China National Knowledge Infrastructure (CNKI), Wanfang Databases were searched for appropriate articles. Randomized trials of RYR (not including Xuezhikang and Zhibituo) and placebo as control in patients with dyslipidemia were considered. Two authors read all papers and independently extracted all relevant information. The primary outcomes were serum total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), triglyceride (TG), and high-density lipoprotein cholesterol (HDL-C). The secondary outcomes were increased levels of alanine transaminase, aspartate aminotransferase, creatine kinase, creatinine and fasting blood glucose. Results A total of 13 randomized, placebo-controlled trials containing 804 participants were analyzed. Red yeast rice exhibited significant lowering effects on serum TC [WMD = −0.97 (95% CI: −1.13, −0.80) mmol/L, P<0.001], TG [WMD = −0.23 (95% CI: −0.31, −0.14) mmol/L, P<0.001], and LDL-C [WMD = −0.87 (95% CI: −1.03, −0.71) mmol/L, P<0.001] but no significant increasing effect on HDL-C [WMD = 0.08 (95% CI: −0.02, 0.19) mmol/L, P = 0.11] compared with placebo. No serious side effects were reported in all trials. Conclusions The meta-analysis suggests that red yeast rice is an effective and relatively safe approach for dyslipidemia. However, further long-term, rigorously designed randomized controlled trials are still warranted before red yeast rice could be recommended to patients with dyslipidemia, especially as an alternative to statins.

Dyslipidemia and obesity have been observed in persons with severe anxiety or depression, and in tricyclic antidepressant (TCA) users. This likely contributes to the higher risk of cardiovascular disease (CVD) in anxiety and depressive disorders. We aimed to elucidate whether biological stress systems or lifestyle factors underlie these associations. If so, they may be useful targets for CVD prevention and intervention. Within 2850 Netherlands Study of Depression and Anxiety (NESDA) participants, we evaluated the explaining impact of biological stress systems (i.e., the hypothalamic-pituitary-adrenal [HPA] axis, autonomic nervous system [ANS] and inflammation) and lifestyle factors (i.e., tobacco and alcohol use, and physical activity) on adverse associations of anxiety and depression severity and TCA use with high and low-density lipoprotein cholesterol, triglycerides, body mass index and waist circumference. Through linear regression analyses, percentual change (%Δ) in β was determined and considered significant when %Δ>10. The inflammatory marker C-reactive protein had the most consistent impact (explaining 14-53% of the associations of anxiety and depression severity and TCA use with lipid and obesity levels), followed by tobacco use (explaining 34-43% of the associations with lipids). The ANS mediated all associations with TCA use (explaining 32-61%). The HPA axis measures did not explain any of the associations. Increased dyslipidemia and (abdominal) obesity risk in patients with more severe anxiety disorders and depression may be partly explained by chronic low-grade inflammation and smoking. TCAs may increase metabolic risk through enhanced sympathetic and decreased parasympathetic ANS activity. That the HPA axis had no impact in our sample may reflect the possibility that the HPA axis only plays a role in acute stress situations rather than under basal conditions.

We have described preliminary results of platelet larger cell ratio (P-LCR) analysis, provided by an automated hematology analyzer in patients with hypercholesterolemia and/or hypertriglyceremia. P-LCR values were significantly higher in patients (n = 41) than in control normal group (n = 20) (P < 0.0001). Larger platelets are more reactive and contribute to vasooclusive events in patients with dyslipidemia. P-LCR may be used as an indicator of risk factor for thromboembolic ischemic events.

To promote the concept of POCT and to investigate dyslipidemia in Guangzhou, China, we performed a study examining blood lipids assessed by POCT and reported factors associated with dyslipidemia. This multicenter, cross-sectional study enrolled outpatients from 9 Guangzhou hospitals from May through September 2013. After informed consent was obtained, the following information was collected: age; gender; the presence of diabetes mellitus, obesity, and hypertension as well as current use of cigarettes or alcohol. Patients were asked to fast for 8h before the blood examination performed on a POCT device, the CardioChek PA. Of 4012 patients enrolled (1544 males, 2468 females; mean age 60.35±9.41 years), 1993 (49.7%) patients had dyslipidemia, but only 101 (5.1%) took statins. The multivariate tests of associations between demographic variables, comorbidities, and the risk of having dyslipidemia found that the significant predictors of dyslipidemia were male gender, age ≥60 years, being a current smoker or alcohol drinker, and hypertension. Most dyslipidemia patients in Guangzhou remain untreated. POCT in China is feasible, and its widespread use might improve dyslipidemia awareness, treatment and control.

Cardiovascular diseases (CVDs) are the leading cause of morbidity/mortality worldwide. Dyslipidemia is a major risk factor for premature atherosclerosis and CVD. Lowering low-density-lipoprotein cholesterol (LDL-C) levels is well established as an intervention for the reduction of CVDs. Statins are the first-line drugs for treatment of dyslipidemia, but they do not address all CVD risk. Development of novel therapies is ongoing and includes the following: (i) reduction of LDL-C concentrations using antibodies to proprotein convertase subtilisin/kexin-9, antisense oligonucleotide inhibitors of apolipoprotein B production, microsomal transfer protein (MTP) inhibitors, and acyl-coenzyme A cholesterol acyl transferase inhibitors; (ii) reduction in levels of triglyceride-rich lipoproteins with ω-3 fatty acids, MTP inhibitors, and diacylglycerol acyl transferase-1 inhibitors; and (iii) increase of high-density-lipoprotein (HDL) cholesterol levels, HDL particle numbers, and/or HDL functionality using cholesteryl ester transfer protein inhibitors, HDL-derived agents, apolipoprotein AI mimetic peptides, and microRNAs. Large prospective outcome trials of several of these emerging therapies are under way, and thrilling progress in the field of lipid management is anticipated.

Leukocyte cell-derived chemotaxin 2 (LECT2) is a hepatokine linking obesity to skeletal muscle insulin resistance. Although previous studies reported that obesity was associated with high levels of circulating LECT2 in human, the associations of detailed body fat distribution with LECT2 levels have not been examined. Furthermore, although animal study suggested that exercise decreased circulating LECT2 levels, it remains unknown whether physical fitness is associated with LECT2 levels in human. We therefore examined the relationship of plasma LECT2 levels with various adiposity indices and cardiorespiratory fitness (CRF) in middle-aged and elderly Japanese men. Furthermore, we examined the relationship of LECT2 levels with the presence of metabolic syndrome, hypertension, insulin resistance and dyslipidemia to determine the clinical significance of measuring circulating LECT2. This was a cross-sectional study of 143 Japanese men (age: 30-79 years). Participants' plasma LECT2 levels were measured by an enzyme-linked immunosorbent assay. To assess their abdominal fat distributions, visceral fat area (VFA) and subcutaneous fat area (SFA) were measured using magnetic resonance imaging. CRF was assessed by measuring peak oxygen uptake ([Formula: see text]). All adiposity indices measured in this study were positively correlated with plasma LECT2 levels, while [Formula: see text] was negatively correlated with LECT2 levels after adjustment for age. The correlations, except for VFA were no longer significant with further adjustment for VFA. Stepwise multiple linear regression analysis revealed that VFA was the strongest predictor of plasma LECT2 levels. Plasma LECT2 levels differed based on the presence of metabolic syndrome and dyslipidemia, but not hypertension and insulin resistance. Logistic regression analyses revealed that plasma LECT2 levels were significantly associated with dyslipidemia independently of VFA; VFA was not significantly associated with dyslipidemia

Introduction Low levels of food security are associated with dyslipidemia and chronic disease in adults, particularly in women. There is a gap in knowledge about the relationship between food security among youth and dyslipidemia and chronic disease. We investigated the relationship between food security status and dyslipidemia among low-income adolescents. Methods We analyzed data from adolescents aged 12 to 18 years (N = 1,072) from households with incomes at or below 200% of the federal poverty level from the National Health and Nutrition Examination Survey (NHANES) 2003–2010. We used logistic regression to examine the relationship between household food security status and the odds of having abnormalities with fasting total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), serum triglycerides (TGs), high-density lipoprotein cholesterol (HDL-C), TG/HDL-C ratio, and apolipoprotein B (Apo B). Models included age, sex, race/ethnicity, smoking status, partnered status in the household, and maternal education, with additional adjustment for adiposity. Results Household food security status was not associated with elevated TC or LDL-C. Adolescents with marginal food security were more likely than food-secure peers to have elevated TGs (odds ratio [OR] = 1.86; 95% confidence interval [CI], 1.14–3.05), TG/HDL-C ratio (OR = 1.74; 95% CI, 1.11–2.82), and Apo B (OR = 1.98; 95% CI, 1.17–3.36). Female adolescents with marginal food security had greater odds than male adolescents of having low HDL-C (OR = 2.69; 95% CI, 1.14–6.37). No elevated odds of dyslipidemia were found for adolescents with low or very low food security. Adjustment for adiposity did not attenuate estimates. Conclusion In this nationally representative sample, low-income adolescents living in households with marginal food security had increased odds of having a pattern consistent with atherogenic dyslipidemia, which represents a cardiometabolic burden above their risk from adiposity

Dyslipidemias have been shown to bear a close association with an increased risk of cardiovascular diseases, atherosclerosis in particular. As efforts are being made to find alternative therapies and ways to prevent disease, there is a corresponding rise in public interest in food and/or active food components that contribute to an improved lipid profile and, thus, to better health. Besides supplying the basic nutrients necessary for well-being, some foods add further physiologic benefits. In fact, specific foods and bioactive components could be beneficial in controlling dyslipidemias. From a review of the literature on foods and bioactive compounds, their recommended quantities, and expected effects, we found that the following nutrients and food components could positively impact the lipid profile: monounsaturated and polyunsaturated fatty acids, soluble fiber, vegetable proteins, phytosterols, and polyphenols. Therefore, incorporating these components into the regular diets of individuals is justified, because they contribute additional positive effects. This suggests that they also be recommended in clinical practice. PMID:26567195

Geographical and environmental features such as urbanization and altitude may influence individual's lipid profiles because of the diversity of human-environment interactions including lifestyles. To characterize the association between altitude and urbanization and lipid profile among Peruvian adults aged ≥35 years. Cross-sectional analysis of the CRONICAS Cohort Study. The outcomes of interest were 6 dyslipidemia traits: hypertriglyceridemia, high low-density lipoprotein cholesterol, low high-density lipoprotein cholesterol (HDL-c), nonisolated low HDL-c, isolated low HDL-c, and high non-HDL-c. The exposures of interest were urbanization level (highly urban, urban, semi-urban, and rural) and altitude (high altitude vs sea level). Prevalence ratios (PRs) and 95% confidence intervals (95% CIs) were calculated using Poisson regression models with robust variance adjusting for potential confounders. Data from 3037 individuals, 48.5% males, mean age of 55.6 (standard deviation ±12.7) years, were analyzed. The most common dyslipidemia pattern was high non-HDL-c with a prevalence of 88.0% (95% CI: 84.9%-90.7%) in the rural area and 96.0% (95% CI: 94.5%-97.1%) in the semi-urban area. Relative to the highly urban area, living in rural areas was associated with a lower prevalence of hypertriglyceridemia (PR = 0.75; 95% CI: 0.56-0.99) and high non-HDL-c (PR = 0.96; 95% CI: 0.93-0.99), whereas living in semi-urban areas was associated with higher prevalence high low-density lipoprotein cholesterol (PR = 1.37; 95% CI: 1.11-1.67). Compared with sea level areas, high-altitude areas had lower prevalence of high non-HDL-c (PR = 0.97; 95% CI: 0.95-0.99). Urbanization but not altitude was associated to several dyslipidemia traits, with the exception of high non-HDL-c in high altitude settings. Copyright © 2017 National Lipid Association.

Given the characteristic atherogenic dyslipidemia of south Indian population and crucial role of APOA1, APOC3, APOA4 and APOA5 genes clustered in 11q23.3 chromosomal region in regulating lipoprotein metabolism and cholesterol homeostasis, a large number of recently identified variants are to be explored for their role in regulating the serum lipid parameters among south Indians. Using fluidigm SNP genotyping platform, a prioritized set of 96 SNPs of the 11q23.3 chromosomal region were genotyped on 516 individuals from Hyderabad, India, and its vicinity and aged >45 years. The linear regression analysis of the individual lipid traits viz., TC, LDLC, HDLC, VLDL and TG with each of the 78 SNPs that confirm to HWE and with minor allele frequency > 1%, suggests 23 of those to be significantly associated (p ≤ 0.05) with at least one of these quantitative traits. Most importantly, the variant rs632153 is involved in elevating TC, LDLC, TG and VLDLs and probably playing a crucial role in the manifestation of dyslipidemia. Additionally, another three SNPs rs633389, rs2187126 and rs1263163 are found risk conferring to dyslipidemia by elevating LDLC and TC levels in the present population. Further, the ROC (receiver operating curve) analysis for the risk scores and dyslipidemia status yielded a significant area under curve (AUC) = 0.675, suggesting high discriminative power of the risk variants towards the condition. The interaction analysis suggests rs10488699-rs2187126 pair of the BUD13 gene to confer significant risk (Interaction odds ratio = 14.38, P = 7.17 × 10 5 ) towards dyslipidemia by elevating the TC levels (β = 37.13, p = 6.614 × 10 5 ). On the other hand, the interaction between variants of APOA1 gene and BUD13 and/or ZPR1 regulatory genes at this region are associated with elevated TG and VLDL. The variants at 11q23.3 chromosomal region seem to determine the quantitative lipid traits and in turn dyslipidemia in the population of Hyderabad

OBJECTIVE It has recently been highlighted that proinflammatory (M1) macrophages predominate over anti-inflammatory (M2) macrophages in obesity, thereby contributing to obesity-induced adipose inflammation and insulin resistance. A recent clinical trial revealed that highly purified eicosapentaenoic acid (EPA) reduces the incidence of major coronary events. In this study, we examined the effect of EPA on M1/M2-like phenotypes of peripheral blood monocytes in obese dyslipidemic patients. RESEARCH DESIGN AND METHODS Peripheral blood monocytes were prepared from 26 obese patients without and 90 obese patients with dyslipidemia. Of the latter 90 obese patients with dyslipidemia, 82 patients were treated with or without EPA treatment (1.8 g daily) for 3 months. RESULTS Monocytes in obese patients with dyslipidemia showed a significantly lower expression of interleukin-10 (IL-10), an M2 marker, than those without dyslipidemia. EPA significantly increased serum IL-10 and EPA levels, the EPA/arachidonic acid (AA) ratio, and monocyte IL-10 expression and decreased the pulse wave velocity (PWV), an index of arterial stiffness, compared with the control group. After EPA treatment, the serum EPA/AA ratio was significantly correlated with monocyte IL-10 expression. Only increases in monocyte IL-10 expression and serum adiponectin were independent determinants of a decreased PWV by EPA. Furthermore, EPA significantly increased the expression and secretion of IL-10 in human monocytic THP-1 cells through a peroxisome proliferator–activated receptor (PPAR)γ-dependent pathway. CONCLUSIONS This study is the first to show that EPA increases the monocyte IL-10 expression in parallel with decrease of arterial stiffness, which may contribute to the antiatherogenic effect of EPA in obese dyslipidemic patients.

Little is known about sex gap in the management and outcomes of dyslipidemia among diabetics in the Arabian Gulf. The aim if this study was to determine sex differences in the management and outcomes of dyslipidemia in diabetic patients in the Arabian Gulf. This study was derived from the Centralized Pan-Middle-East Survey on the management of hypercholesterolemia. Patients recruited were aged ≥18 years on lipid lowering drugs for ≥3 months (stable medication for ≥6 weeks). Outcomes were based on the joint Consensus Statement of the American Diabetes Association and American College of Cardiology Foundation. Analyses were performed using univariate and multivariate logistic regression techniques. The mean age of the cohort (n = 3336) was 57 ± 11 years and 45% (n = 1486) were females. Females were less likely to be on rosuvastatin (7.6% vs 12%; P < 0.001), atorvastatin (41% vs 46%; P = 0.005) and combination hypolipidemic therapy (5.6% vs 2.8%; P < 0.001) but more likely to be on simvastatin (51% vs 39%; P < 0.001) than males. Females, especially those with very high atherosclerotic cardiovascular disease (ASCVD) risk status, were also less likely to achieve LDL-cholesterol [adjusted odds ratio (aOR), 0.58; 95% confidence interval (CI): 0.40-0.86; P = 0.006], non-HDL-cholesterol [aOR, 0.68; 95% CI: 0.46-0.99; P = 0.048] and apolipoprotein B [aOR, 0.64; 95% CI: 0.44-0.92; P = 0.016] lipid targets. Diabetic women were less likely to be on optimal hypolipemic therapy and consequently less likely to attain lipid goals compared to men. This shows a sex gap on dyslipidemia treatment in the region. Diabetic women with very high ASCVD risk status need to be aggressively treated to lower their risk of cardiovascular events.

Obesity and diabetes are contributed to cardiovascular disease risk. The current study was performed to evaluate the association of central and general obesity and cardio-metabolic risk factors, including dyslipidemia and hypertension in T2DM patients. This was a cross-sectional study in T2DM adults. Body mass index (BMI) was used to identify general obesity and waist circumference (WC) was measured to define abdominal obesity (based on ATP III). Biochemical analyses, and anthropometric and blood pressure measurements were done for all participants. Participants with central obesity showed significantly higher systolic (132.5mmHg vs. 125.4mmHg, p=0.024) and diastolic blood pressures (84.9mmHg vs. 80mmHg, p=0.007) than participants without obesity. Dyslipidemia was more prevalent in all participants either by BMI (98.3% vs. 97%, 95% CI: 0.18-17.53) or by WC (97.2% vs. 98%, 95% CI: 0.07-7.19). Abdominal adiposity in diabetic subjects showed significant reverse association with high level of physical activity (OR=0.22, 95% CI: 0.06-0.85). Hypertriglyceridemia rate was increased with both central (OR=2.11; p=0.040) and general obesity (OR=2.68; p=0.021). After adjustment for energy intake and age, females had higher risk of general (OR=4.57, 95% CI=1.88-11.11) and central obesity (OR=7.93, 95% CI=3.48-18.08). Females were more susceptible to obesity. Hypertension was associated with both obesity measures. Dyslipidemia, except for hypertriglyceridemia, was correlated to neither abdominal nor general obesity. Copyright © 2016 Diabetes India.

Dyslipidemia is a primary driver for chronic cardiovascular conditions and there is no comprehensive literature about its management in South Africa. The objective of this study was to assess the prevalence, awareness, treatment, and control of dyslipidemia in rural South Africa and how they are impacted by different behaviors and non-modifiable factors. To fulfill this objective we recruited for this cohort study adults aged ≥40 years residing in the Agincourt sub-district of Mpumalanga Province. Data collection included socioeconomic and clinical data, anthropometric measures, blood pressure (BP), HIV-status, point-of-care glucose and lipid levels. Framingham CVD Risk Score was ascribed to patients based upon categories for 10 year cardiovascular risk of low (<3%), moderate (≥3% and <15%), high (≥15% and <30%), and very high (≥30%).LDL cholesterol control by risk category was defined according to South African Guidelines. Multivariable logistic regression models were built to identify factors that were significantly associated with dyslipidemia and awareness of dyslipidemia From 5,059 respondents a total of 4247 subjects (83.9%) had their cholesterol levels measured and were included in our analysis. Overall, 67.3% (2860) of these met criteria for dyslipidemia, only 30 (1.05%) were aware of their condition, and only 21 subjects (0.73%) were on treatment. The majority have abnormalities in triglycerides (59.3%). As cardiovascular risk increased the rates of lipid control according to LDL level dropped. Multivariate logistic regression analyses showed that being overweight was predictive of dyslipidemia (OR 1.76; 95%CI 1.51-2.05, p<0.001) and dyslipidemia awareness (OR 2.58; 95%CI 1.19-5.58; p = 0.017). In conclusion, the very low awareness and treatment of dyslipidemia in this cohort indicate a greater need for systematic screening and education within the population and demonstrate that there are multiple opportunities to allay this burden.

Plasma levels of proprotein convertase subtilisin/kexin type 9 (PCSK9), apolipoprotein C-III (apoC3) and small dense low density lipoprotein cholesterol (sdLDL-C), have been recently recognized as circulating atherosclerosis-related lipid measurements. We aimed to elucidate their associations with current dyslipidemias, and identify their levels at increased risk to dyslipidemia. A total of 1,605 consecutive, non-treated patients undergoing diagnostic/interventional coronary angiography were examined. Plasma PCSK9 and apoC3 levels were determined using a validated ELISA assay, and sdLDL-C was measured by the Lipoprint LDL System. Plasma levels of PCSK9, apoC3, and sdLDL-C were associated with the current dyslipidemias classification (all p<0.001). PCSK9 significantly conferred prediction of both hypercholesterolemia and combined hyperlipidemia at a level of 235 ng/ml; apoC3 levels for hypertriglyceridemia, hypercholesterolemia and combined hyperlipidemia were 80.0, 71.5, and 86.4 μg/ml, respectively; and sdLDL-C for hypertriglyceridemia, hypercholesterolemia, combined hyperlipidemia and hypo high density lipoprotein (HDL) cholesterolemia 3.5, 2.5, 4.5, and 2.5 mg/dl, respectively (all p<0.001 for area under the receiver-operating characteristic curve). In a polytomous logistic model comparing increasing LDL-C categories, the interactions with high PCSK9, apoC3, and sdLDL-C elevated gradually. Similarly, apoC3 and sdLDL-C showed elevated interaction with increased triglyceride categories, and only sdLDL-C showed interaction with decreased HDL cholesterol (HDL-C) categories. Furthermore, discordances of PCSK9, apoC3, and sdLDL-C with current dyslipidemias were observed. PCSK9, apoC3, and sdLDL-C showed significant interactions with current dyslipidemias, and were predictive in the screening. The substantial discordances with current dyslipidemias might provide novel view in lipid management and further cardiovascular benefit.

To assess the prevalence of atherogenic dyslipidemia in hypertensive patients and its relationship with risk profile and blood pressure control. The study included 24 351 hypertensive patients from the Spanish Ambulatory Blood Pressure Monitoring Registry. Atherogenic dyslipidemia was defined as the presence of hypertriglyceridemia (> 150mg/dL) and low levels of high-density lipoprotein cholesterol (< 40mg/dL in men and < 46mg/dL in women). Blood pressure control was assessed by office and ambulatory monitoring. Atherogenic dyslipidemia was present in 2705 patients (11.1%). Of these, 30% had hypertriglyceridemia and 21.7% had low levels of high-density lipoprotein cholesterol. Compared with patients without these risk factors, the former group were more often male (60% vs 52%), younger (57 years vs 59 years), had other risk factors and organ damage (microalbuminuria, reduced estimated glomerular filtration rate, and left ventricular hypertrophy), worse office, diurnal, and nocturnal blood pressure values (odds ratio 1.09, 1.06, and 1.10, respectively), and the lowest nocturnal blood pressure reduction (odds ratio=1.07), despite the greater use of antihypertensive drugs. Atherogenic dyslipidemia is present in more than 10% of hypertensive patients and is associated with other risk factors, organ damage, and poorer blood pressure control. Greater therapeutic effort is needed to reduce overall risk in these patients. Copyright © 2014 Sociedad Española de Cardiología. Published by Elsevier España, S.L.U. All rights reserved.

Background The current challenge in managing people living with human immunodeficiency virus (PLWHIV) includes the identification and monitoring for comorbid health risks associated with HIV and its treatment and longer survival. Dyslipidemia, diabetes mellitus and metabolic syndrome are increasingly seen in PLWHIV. Objective In this narrative review, we aimed to summarize the current knowledge about diabetes, dyslipidemia and metabolic syndrome in PLWHIV in Africa and also to discuss the challenges that patients as well as health authorities in Africa may face. Methods PubMed and Google scholar published-English literatures concerning earlier mentioned entities regardless of time limit were critically reviewed. Results The prevalence of metabolic disorders in HIV population in Africa was estimated to range from 2.1% to 26.5% for diabetes and 20.2% to 43.5% for pre-diabetes, 13% to 58% for metabolic syndrome and 13% to 70% for dyslipidemia. Conclusion The management of metabolic disorders and cardiovascular disease risks related to HIV is complex especially in Africa due to healthcare resources, but our experience suggests that metabolic clinic is beneficial to patients and staff and should be an important part of HIV services especially as the older HIV population is increasing. In this context, cardiovascular risk assessment of HIV-infected patients will become an important component of care in developing countries in Africa and strategies are needed to deal with progressive increase in the epidemic of type 2 diabetes, dyslipidemia and metabolic syndrome.

In 1995, the South Korean government made nutrition labeling compulsory, which has positively impacted patients with certain chronic diseases, such as dyslipidemia. We investigated the association between nutrition labeling-based awareness and the risk of dyslipidemia among individuals not yet diagnosed. Our study used data from the fifth Korea National Health and Nutrition Examination Surveys administered during 2010-2014 (n = 17,687). We performed multiple or logistic regression analysis to examine the association between nutritional analysis and various outcome variables. Approximately 70 % of the respondents (n = 11,513) were familiar with nutrition labeling, of which 20 % (n = 3172) decided what food to buy based on that information. This awareness yielded mostly positive results on outcome indicators, such as triglyceride and high-density lipoprotein cholesterol levels. In general, individuals who used nutritional labels to make decisions regarding food purchases had a lower risk of dyslipidemia than individuals who did not (OR: 0.806, 95 % CI: 0.709-0.917). Utilizing nutrition labels for making food choices correlated with a lower risk of dyslipidemia in certain subgroups. Based on our findings, we recommend that health policymakers and medical professionals consider promoting nutrition labeling as an alternative method for managing certain chronic diseases in South Korean patients.

The Basic Health Research of the Ministry of Health Indonesia in 2008 reported that the single most important cause of death was stroke, in both urban and rural populations. The risk factors underlying the cause of death are associated with hypertension, obesity and dyslipidemia. The purpose of this study was to determine the mean intake of trans fatty acids and its relation to dyslipidemia in a sample of Indonesian adults. A cross-sectional study was conducted on a total of 180 adult male and female respondents aged 35-60 years living in rural and urban areas of Depok city, West Java. Dietary intake was assessed by means of 24-hour recall and semi-quantitative FFQ. The mean intake of trans fatty acids was 0.48% of total calories (urban 0.40% and rural 0.55%). The prevalence of dyslipidemia in the rural and urban subjects were 61.1% and 66.7%, respectively. There was a statistically significant relationship between trans fatty acids intake and hypercholesterolemia and hypertriglyceridemia. The intake of trans fatty acid among the Indonesian adults studied was half the recommended level. The high prevalence of dyslipidemia found indicates the need for intervention to reduce the rising incidence of cardiovascular diseases in Indonesia.

Familial combined hyperlipidemia (FCH) is a complex and common familial dyslipidemia characterized by elevated total cholesterol and/or triglyceride levels with over five-fold risk of coronary heart disease. The genetic architecture and contribution of rare Mendelian and common variants to FCH susceptibility is unknown. In 53 Finnish FCH families, we genotyped and imputed nine million variants in 715 family members with DNA available. We studied the enrichment of variants previously implicated with monogenic dyslipidemias and/or lipid levels in the general population by comparing allele frequencies between the FCH families and population samples. We also constructed weighted polygenic scores using 212 lipid-associated SNPs and estimated the relative contributions of Mendelian variants and polygenic scores to the risk of FCH in the families. We identified, across the whole allele frequency spectrum, an enrichment of variants known to elevate, and a deficiency of variants known to lower LDL-C and/or TG levels among both probands and affected FCH individuals. The score based on TG associated SNPs was particularly high among affected individuals compared to non-affected family members. Out of 234 affected FCH individuals across the families, seven (3%) carried Mendelian variants and 83 (35%) showed high accumulation of either known LDL-C or TG elevating variants by having either polygenic score over the 90th percentile in the population. The positive predictive value of high score was much higher for affected FCH individuals than for similar sporadic cases in the population. FCH is highly polygenic, supporting the hypothesis that variants across the whole allele frequency spectrum contribute to this complex familial trait. Polygenic SNP panels improve identification of individuals affected with FCH, but their clinical utility remains to be defined. PMID:27227539

Dyslipidemia is the primary risk factor for arthrosclerosis. It is the most common chronic disease among the multiethnic Asian population in Singapore. Local national health survey has shown ethnic variability in achieving control of dyslipidemia. This study aimed to determine the proportion of patients in primary care, who achieved their low-density lipoprotein (LDL)-cholesterol treatment goals, stratified by the local major ethnic groups. It also evaluated the factors that affected their dyslipidemia control, including diet, exercise and medication usage. Research assistants administered questionnaires on adult patients with physician-diagnosed dyslipidemia to determine their views on diet, exercise, and medications in this cross-sectional study in 2 local primary care clinics. Their lipid profiles were retrieved from their laboratory reports in their electronic health records. Chi-square and Fisher exact tests were used for the categorical demographics and questionnaire variables, (P < .05: statistically significant). Logistic regression was performed using these significant variables to determine the adjusted odds of the ethnic groups. A total of 1093 eligible patients completed the questionnaires. The proportion of Chinese, Malay, and Indian patients who achieved LDL-cholesterol goals was 78.3%, 67.9%, and 68.5%, respectively. Among those who self-reported taking their favorite cholesterol-rich food occasionally when their cholesterol became controlled, 35.8% Indians failed to achieve treatment goals, compared to 20.1% Chinese and 30.9% Malay patients. Regular medication adherence was associated with 81.8% Chinese, 69.0% Malay, and 69.7% Indian reaching treatment goals. More Chinese met LDL-cholesterol treatment goals compared to Malays and Indians. Lipid-lowering medications enabled but smoking hindered their achievement of these treatment goals.

Non-communicable diseases are a public health problem in México. Coronary heart disease and diabetes mellitus are the first and second cause of death in the country, followed by thrombotic cerebrovascular events. Cardiovascular diseases are the leading cause of death; one primary risk factor is hypercholesterolemia. The detection and treatment of lipid abnormalities is the key to the prevention and management of chronic non-communicable diseases. Two nationally representative surveys have shown that lipid abnormalities are the most common risk factors in Mexican adults. The purpose of this guide is to provide a basis for identifying dyslipidemia in a timely manner, and to systematize the criteria for diagnosis and treatment in the first and second level of care.

This study investigated the prevalence of atherogenic dyslipidemia (AD) in Chinese outpatients whose low-density lipoprotein cholesterol (LDL-C) levels reached the goals with statin monotherapy and evaluated the characteristics of these patients. An analysis of the Dyslipidemia International Survey-China study that was carried out at 122 hospitals in China. Among patients reaching their LDL-C goals, the presence of AD was defined as triglyceride levels ≥1.7mmol/L and/or low levels of high-density lipoprotein cholesterol (men: <1.0mmol/L; women: <1.3mmol/L). 22,039 patients receiving statin monotherapy were analyzed. According to the American National Cholesterol Education Program Adult Treatment Panel III, 13,088 patients reached LDL-C goals, and 7134 patients of them had AD. Age, male gender, BMI, sedentary lifestyle, diabetes mellitus, ischemic cerebrovascular disease, serum uric acid levels, and fasting plasma glucose (all P<0.05) were independently associated with AD. Based on the Chinese guideline for the management of dyslipidemia, 13,551 patients reached LDL-C goals, and 7719 patients of them had AD. Age, male gender, BMI, sedentary lifestyle, coronary heart disease, serum uric acid levels, and fasting plasma glucose (all P<0.05) were independently associated with AD. The intensity of statin therapy did not affect the prevalence of AD. There was a high prevalence of AD in Chinese patients with optimal statin treatment. Some risk factors associated with AD were identified, but these factors were slightly different according to two criteria/guidelines. The intensity of statin therapy did not reduce the prevalence of AD. A combination lipid therapy may be more suitable for Chinese patients. Copyright © 2017 Elsevier Ireland Ltd.

A comprehensive review was performed to investigate the effect of route of administration on medication adherence and persistence in rheumatoid arthritis (RA) and to compare adherence/persistence with oral medications between RA and a non-painful disease (dyslipidemia). Comprehensive database searches were performed to identify studies investigating medication adherence and/or persistence in adults with RA receiving conventional synthetic or biologic agents. Similar searches were performed for studies of patients with dyslipidemia receiving statins. Studies had to be published after 1998 in English and involve ≥6 months' follow up. Adherence and persistence were compared between the different routes of drug administration in RA, and between the two diseases for oral medications. A total of 35 and 28 papers underwent data extraction for RA and dyslipidemia, respectively. Within the constraints of the analysis, adherence and persistence rates appeared broadly similar for the different routes of drug administration in RA. Adherence to oral medications was also broadly similar across the two diseases, but persistence was lower in dyslipidemia. Poor adherence has clinical consequences in both diseases: greater disease activity and risk of flare in RA, and increased serum cholesterol levels and risk of heart and cerebrovascular disease in dyslipidemia. Over 1-3 years, poor adherence to biologic RA medications led to increased resource use and medical costs but lower total direct costs due to reduced biologic drug costs. Conversely, poor adherence to dyslipidemia medications resulted in increased total direct costs. In both diseases, adherence improved with patient education/support. The route of drug administration and the symptomatic (pain) nature of the disease do not appear to be dominant factors for drug adherence or persistence in RA. The wide range of adherence and persistence values and definitions across studies made comparisons between drug formulations and

Accumulating researches reported that particulate matter (PM2.5) is a risk factor for developing various diseases, including metabolic syndrome. Recently, inactive rhomboid protein 2 (iRhom2) was considered as a necessary modulator for shedding of tumor necrosis factor-α (TNF-α) in immune cells. TNF-α, a major pro-inflammatory cytokine, was linked to various pathogenesis of diseases, including dyslipidemia. Here, wild type (WT) and iRhom2-knockout (iRhom2 -/- ) mice were used to investigate the effects of iRhom2 on PM2.5-induced hepatic dyslipidemia. The hepatic histology, inflammatory response, glucose tolerance, serum parameters and gene expressions were analyzed. We found that long-term inhalation of PM2.5 resulted in hepatic steatosis. And a significant up-regulation of iRhom2 in liver tissues was observed, accompanied with elevated TNF-α, TNF-α converting enzyme (TACE), TNFα receptor (TNFR)2 and various inflammatory cytokines expressions. Additionally, PM2.5 treatment caused TG and TC accumulation in serum and liver, probably attributed to changes of genes modulating lipid metabolism. Intriguingly, hepatic injury and dyslipidemia were attenuated by iRhom2 -/- in mice with PM2.5 challenge. In vitro, iRhom2-knockdwon reduced TNF-α expressions and its associated inflammatory cytokines in Kupffer cells, implying that liver-resident macrophages played an important role in regulating hepatic inflammation and lipid metabolism in cells treated with PM2.5. The findings indicated that long-term PM2.5 exposure caused hepatic steatosis and dyslipidemia through triggering inflammation, which was, at least partly, dependent on iRhom2/TNF-α pathway in liver-resident macrophages.

We investigated the individual and joint effects of hypertension, smoking, dyslipidemia, and obesity and angiotensin-converting enzyme (ACE) DD genotype on albuminuria in Taiwanese type 2 diabetic patients. ACE genotypes were determined in 519 (287 men and 232 women) patients aged 58.5 (SD: 9.0) years. Among them, 240 had albuminuria (urinary albumin-to-creatinine ratio > or =30 microg/mg). Logistic regression was used to evaluate the individual and joint effects of risk factors and DD classified by two-by-four table. The adjusted odds ratios were significant for hypertension, smoking and obesity but not for DD and dyslipidemia in models evaluating individual effects. However, while analyzing the joint effects of DD and hypertension, smoking, dyslipidemia and obesity, the respective adjusted odds ratios were 3.253 (1.261-8.391), 3.016 (1.086-8.376), 2.385 (1.010-5.630) and 2.508 (1.117-5.631). Hypertension, smoking, dyslipidemia and obesity jointly play an important role with DD genotype in mediating albuminuria. 2010 The Canadian Society of Clinical Chemists. Published by Elsevier Inc.

Polymorphisms in apolipoprotein A5 gene (APOA5) have been associated with higher triglyceride levels in many populations. The aim of the study was to determine the allelic and genotypic distribution of the APOA5 -1131T>C polymorphism and to identify the association of the genetic variant and the risk for dyslipidemia. We genotyped 109 dyslipidemic subjects and 107 controls. The total cholesterol, triglycerides and HDL-c were determined enzymatically. Comparison of means among groups was calculated by ANOVA. Significant differences among groups were evaluated by Student-Newman-Keuls test. The minor allele C was more frequent in dyslipidemic subjects than controls (p=0.019) and confers an increased individual risk for dyslipidemia (OR=1.726, CI 95%=1.095-2.721). The genotype analysis by gender showed that this allele was more frequent in dyslipidemic males (p=0.037; OR=2.050, CI 95%=1.042-4.023). When participants were analyzed according to genotypes TT and TC/CC, C-carriers presented higher cholesterol and triglycerides levels than TT homozygous (p=0.046 and 0.049, respectively). The allele C confers higher total cholesterol and triglycerides levels in dyslipidemic adults. The APOA5 -1131T>C polymorphism is associated with dyslipidemia in male subjects.

Background Clinical inertia has been defined as mistakes by the physician in starting or intensifying treatment when indicated. Inertia, therefore, can affect other stages in the healthcare process, like diagnosis. The diagnosis of dyslipidemia requires ≥2 high lipid values, but inappropriate behavior in the diagnosis of dyslipidemia has only previously been analyzed using just total cholesterol (TC). Objectives To determine clinical inertia in the dyslipidemia diagnosis using both TC and high-density lipoprotein cholesterol (HDL-c) and its associated factors. Design Cross-sectional. Setting All health center visits in the second half of 2010 in the Valencian Community (Spain). Patients 11,386 nondyslipidemic individuals aged ≥20 years with ≥2 lipid determinations. Measurement Variables Gender, atrial fibrillation, hypertension, diabetes, cardiovascular disease, age, and ESCARVAL training course. Lipid groups: normal (TC<5.17 mmol/L and normal HDL-c [≥1.03 mmol/L in men and ≥1.29 mmol/L in women], TC inertia (TC≥5.17 mmol/L and normal HDL-c), HDL-c inertia (TC<5.17 mmol/L and low HDL-c), and combined inertia (TC≥5.17 mmol/L and low HDL-c). Results TC inertia: 38.0% (95% CI: 37.2–38.9%); HDL-c inertia: 17.7% (95% CI: 17.0–18.4%); and combined inertia: 9.6% (95% CI: 9.1–10.2%). The profile associated with TC inertia was: female, no cardiovascular risk factors, no cardiovascular disease, middle or advanced age; for HDL-c inertia: female, cardiovascular risk factors and cardiovascular disease; and for combined inertia: female, hypertension and middle age. Limitations Cross-sectional study, under-reporting, no analysis of some cardiovascular risk factors or other lipid parameters. Conclusions A more proactive attitude should be adopted, focusing on the full diagnosis of dyslipidemia in clinical practice. Special emphasis should be placed on patients with low HDL-c levels and an increased cardiovascular risk. PMID:24626597

Retrospective cohort study. The study was conducted using a nationally representative sample of 1 million National Health Insurance enrollees. Newly diagnosed patients with OA (N=13,545). One-to-one propensity score matching was used to match patients who received PT within the first year of OA diagnosis (PT group; n=3403) with an equal number of patients with OA who did not receive PT (non-PT group). Not applicable. The 4-year cumulative risk of comorbidities including coronary artery disease (CAD), diabetes mellitus, dyslipidemia, osteoporosis, gastrointestinal tract ulcer, and renal failure was estimated. A Cox proportional hazards regression analysis was performed to identify the dose-response relation between the PT dosage and the risk of OA-related comorbidities. A total of 3403 patients (25.1%) received PT within the first year of OA diagnosis. The PT group had a significantly lower 4-year cumulative risk of dyslipidemia (P=.05) and a potentially lower 4-year cumulative risk of CAD (P=.09). After adjusting for other potential confounders, the Cox proportional hazards regression analysis showed that patients with OA who received a high PT dosage had a low risk of CAD and dyslipidemia. Patients with OA who received PT had a lower risk of OA-related comorbidities such as dyslipidemia or CAD. Copyright © 2016 American Congress of Rehabilitation Medicine. Published by Elsevier Inc.

Cholesteryl ester transfer protein (CETP) is involved in diabetic dyslipidemia. We aim to test the hypothesis that CETP might be of importance in mediating dyslipidemia-related susceptibility to cognitive deficits in diabetic patients. We recruited 190 type 2 diabetic patients and divided them into two groups according to the Montreal Cognitive Assessment (MoCA) score. The association between CETP and cognitive decline was analyzed with logistic regression and stratification. There were 110 diabetic patients with mild cognition impairment (MCI) and 80 healthy cognition subjects as controls. Dyslipidemia is more common among diabetic patients with MCI; they had a significant increase of serum CETP concentrations, which was negatively correlated with MoCA (r = -0.638; p < 0.001). Negative correlations were also found between the serum CETP concentration with the Auditory Verbal Learning Test (r = -0.266; p = 0.008), indicating memory deficit. Logistic regression analysis revealed that CETP concentration was an independent factor of diabetic MCI (p < 0.001). Further stratification study showed that high serum levels of CETP was an independent risk factor of MCI in diabetic patients with a low density lipoproteins level ≥2.59 mmol/L, or high density lipoproteins level ≤1.0 mmol/L for men and ≤1.3 mmol/L for women, or TG level ≥1.7 mmol/L, after adjusting for age, sex, education, and glucose control (all ps < 0.05). CETP was intimately involved in dyslipidemia-related susceptibility to cognitive decline, especially memory function in type 2 diabetic patients.

Diabetic nephropathy is a leading cause of end-stage kidney disease in the world. Although various types of treatment for diabetes, hypertension and dyslipidemia have improved prognosis and quality of life in patients with diabetic nephropathy, there still exist some diabetic patients with severe proteinuria showing poor prognosis. This clinical trial, LICENSE, aims to confirm the impact of LDL apheresis on proteinuria exhibiting hyporesponsiveness to treatment. This ongoing trial is a multicenter, prospective study of diabetic patients with severe proteinuria. The objective is to examine the impact of LDL apheresis on proteinuria in patients with diabetic nephropathy. The other subject is to investigate safety of LDL apheresis in these patients. The subjects consist of diabetic patients with serum creatinine (Cr) levels below 2 mg/dL who present severe proteinuria above 3 g/g Cr or 3 g/day and LDL cholesterol above 120 mg/dL. The target number of registered patients will be 35 patients. Urinary protein excretion and renal function will be observed for 24 weeks after the treatment of LDL apheresis. This study will determine the effectiveness and safety of LDL apheresis for diabetic nephropathy patients with severe proteinuria and dyslipidemia.

Recently, aging has been shown to be associated with sarcopenic obesity (SO), of which decreased muscle mass and increased fat mass are features. Sarcopenia and obesity alone are known to be associated with abnormal lipid metabolism. However, it remains unclear whether SO has greater adverse effects on dyslipidemia than on sarcopenia or obesity alone. We aimed to investigate the association between SO and dyslipidemia in elderly Koreans. This study was based on data collected during the 2008-2010 Korea National Health and Nutrition Examination Survey. We included 1,466 men and 2,017 women aged 65 years and over. Sarcopenia was indicated in participants with height- or weight-adjusted appendicular skeletal muscle that was 1 standard deviation below the sex-specific mean for the young reference group, and obesity was defined as a body mass index ≥ 25 kg/m(2). Dyslipidemia was defined according to the National Cholesterol Education Program-Adult Treatment Panel III. After adjusting for confounding factors, the SO group had a higher risk for dyslipidemia [odds ratio (OR) 2.82 (95 % confidence interval 1.76-4.51)] than the obese group [2.12 (1.11-4.07)] and sarcopenic group [1.46 (1.01-2.11)] (p < 0.001) only in men. Furthermore, the SO group in men had the highest OR for hypercholesterolemia, hypertriglyceridemia, hypo-high-density lipoprotein cholesterolemia, hyper-low-density lipoprotein cholesterolemia, and a high ratio of triglyceride to high-density lipoprotein cholesterol even after further adjustments. In Korean elderly men, SO was associated with an increased risk for dyslipidemia compared with sarcopenia or obesity alone.

Squalene synthase inhibition: a novel target for the management of dyslipidemia.

A new class of compounds, known as squalene synthase inhibitors, has recently reached phase III clinical trials and may provide another therapeutic option for clinicians to improve risk management of low-density lipoprotein cholesterol (LDL-C). The clinical need for another LDL-C-lowering therapy is evident by the inability to achieve an LDL-C target of less than 70 mg/dL in the majority of very high-risk patients on statin monotherapy. Human clinical trial data with TAK-475, a novel and potent inhibitor of squalene synthase, have not yet been published.

Background Lopinavir/ritonavir (LPV/r) is widely used in Cambodia with high efficacy but scarce data exist on long-term metabolic toxicity. Methods We carried out a cross-sectional and retrospective study evaluating metabolic disorders and cardiovascular risk in Cambodian patients on LPV/r-based antiretroviral therapy (ART) for > 1 year followed in Calmette Hospital, Phnom Penh. Data collected included cardiovascular risk factors, fasting blood lipids and glucose, and retrospective collection of bioclinical data. We estimated the 10-year risks of coronary heart disease with the Framingham, Ramathibodi-Electricity Generating Authority of Thailand (Rama-EGAT), and the Data Collection on Adverse Effects of Anti-HIV Drugs (D:A:D) risk equations. We identified patients with LDL above targets defined by the French expert group on HIV and by the HIV Medicine Association of the Infectious Disease Society of America and the Adult AIDS Clinical Trials Group (IDSA-AACTG). Results Of 115 patients enrolled—mean age 40.9 years, 69.2% male, mean time on LPV/r 3.8 years—40 (34.8%) had hypercholesterolemia (> 2.40 g/L), and 69 (60.0%) had low HDL cholesterol (< 0.40 g/L). Twelve (10.5%), 28 (24%) and 9 (7.7%) patients had a 10-year risk of coronary heart disease ≥ 10% according to the Framingham, D:A:D, and Rama-EGAT score, respectively. Fifty one (44.4%) and 36 (31.3%) patients had not reached their LDL target according to IDSA-AACTG and French recommendations, respectively. Conclusion Prevalence of dyslipidemia was high in this cohort of HIV-infected Cambodian patients on LPV/r. Roughly one third had high LDL levels requiring specific intervention. PMID:27579612

To determine the influence of dyslipidemia in control of blood pressure in patients with type 2 Diabetes. To test the hypothesis that, blood pressure and lipid levels are not sufficiently controlled in patients with type 2 Diabetes, in the western region of the Republic of Macedonia. Abnormalities of lipid and lipoprotein levels in the serum (dyslipidemia) are recognized as major modifiable cardiovascular disease risk factors and have been identified as independent risk factors for essential hypertension, giving rise to the term dyslipidemic hypertension. While patient-related data from primary care that demonstrate an under-treatment of blood pressure and dyslipidemia in type 2 Diabetics are vastly available in clinical practice, results from population-based studies are scarce. The study was conducted on outpatients in Primary Health Care Clinics in 8 cities on the western region of the Republic of Macedonia. Prospectively the tests were performed on 600 (45.6% women and 54.4% men) participants with a mean age of 62 ± 5.8. Study participants were selected among primary care patients, who were actively on therapy for diabetes mellitus and hypertension during the period of March 2013 - March 2014. Patients' demographic characteristics, clinical laboratory and drug usage data were obtained. The patients were classified according to the BP control, into 2 groups. A total of 600 patients, of which 45.6% female and 54.3% male, completed the survey and had data for a 1-year medical record review. It was observed that a high percentage, 65.3% of patients, did not have controlled blood pressure despite the ongoing medical treatment, according to evidence and current guidelines in a cohort of hypertensive diabetics.

Previous investigations have shown that inflammation induces changes in lipid and lipoprotein metabolism, and increased expression of angiopoietin-like protein 3 (ANGPTL3) contributes to the development of dyslipidemia. Here we investigated whether there is a correlation between increased ANGPTL3 expression and dyslipidemia in mastitis mice. Thirty mice were divided into two groups: control group and Staphylococcus aureus (S. aureus)-induced mastitis mice group. Changes in the levels of blood lipids [total cholesterol (TC), triglyceride (TG), low-density lipoprotein cholesterol (LDL-C) and high-density lipoprotein cholesterol (HDL-C)]; activity of myeloperoxidase (MPO); concentrations of plasma inflammation biomarkers [interferon-γ (IFNγ), tumor necrosis factor α (TNFα), and interleukin-1α (IL-1α)]; concentration of plasma ANGPTL3 protein; lipoprotein lipase (LPL) activities in postheparin plasma; expressions of hepatic N-acetylgalactosaminyltransferase 2 (GALNT2), hepatic ANGPTL3 and adipose LPL were determined. The major results indicated specific pathological mammary tissue changes, elevated MPO activity, reduced GALNT2 mRNA expression, elevated ANGPTL3 mRNA and protein expression and reduced LPL mRNA and protein expression. In plasma samples the S.aureus infused mice displayed elevated ANGPTL3 protein concentration, TG, TC and LDL-C levels, and reduced postheparin LPL activities and HDL-C level. The data suggests that ANGPTL3 is part of the machinery causing dyslipidemia majorily via LPL inhibition in mastitis mice. Copyright © 2017 Elsevier Inc. All rights reserved.

Lecithin cholesterol acyltransferase (LCAT) plays a pivotal role in HDL metabolism but its influence on atherosclerosis remains controversial for decades both in animal and clinical studies. Because lack of cholesteryl ester transfer protein (CETP) is a major difference between murine and humans in lipoprotein metabolism, we aimed to create a novel Syrian Golden hamster model deficient in LCAT activity, which expresses endogenous CETP, to explore its metabolic features and particularly the influence of LCAT on the development of atherosclerosis. CRISPR/CAS9 gene editing system was employed to generate mutant LCAT hamsters. The characteristics of lipid metabolism and the development of atherosclerosis in the mutant hamsters were investigated using various conventional methods in comparison with wild type control animals. Hamsters lacking LCAT activity exhibited pro-atherogenic dyslipidemia as diminished high density lipoprotein (HDL) and ApoAI, hypertriglyceridemia, Chylomicron/VLDL accumulation and significantly increased ApoB100/48. Mechanistic study for hypertriglyceridemia revealed impaired LPL-mediated lipolysis and increased very low density lipoprotein (VLDL) secretion, with upregulation of hepatic genes involved in lipid synthesis and transport. The pro-atherogenic dyslipidemia in mutant hamsters was exacerbated after high fat diet feeding, ultimately leading to near a 3- and 5-fold increase in atherosclerotic lesions by aortic en face and sinus lesion quantitation, respectively. Our findings demonstrate that LCAT deficiency in hamsters develops pro-atherogenic dyslipidemia and promotes atherosclerotic lesion formation. Published by Elsevier Inc.

Studies have highlighted the association between insulin resistance (IR) and several cardiovascular (CV) risk factors, including hypertension (HTN), obesity, dyslipidemia (i.e. high triglyceride and low HDL-cholesterol) and glucose intolerance, in a cluster known as the metabolic syndrome (MS). There are few data on the frequency of the MS and dyslipidemia in developing countries, and none in South America. To estimate the prevalence of the MS and its components in Zulia State, Venezuela, and to establish associated demographic and clinical factors, we evaluated 3108 Hispanic men and women aged 20 years or older from a cross-sectional survey of a random representative sample from each health district in Zulia State, Venezuela (1999-2001). Prevalence of the MS and dyslipidemia was defined according to the National Cholesterol Education Program (NCEP)/Adult Treatment Panel III (ATP III) criteria. The age-adjusted prevalence of MS and dyslipidemia was 31.2% and 24.1%, respectively, with higher rates in men than in women. Prevalence rates increased with age and with the degree of obesity. MS prevalence was lower in Amerindian (17.%) compared to Black (27.2%), White (33.3%) and Mixed (37.4%) men, but no differences were found among women. Overall, low HDL-cholesterol (65.3%), abdominal obesity (42.9%) and HTN (38.1%) were the most frequent MS components. After adjusting for age, sex and race groups, family history of diabetes, obesity and HTN were associated with the MS. Sedentary lifestyle also increased the risk of MS, event after adjusting for the same covariates, obesity and the degree of IR. These results suggest that MS is found in approximately one-third of the Venezuelan adult population in Zulia State, with higher prevalence in men related to the presence of dyslipidemia. Lifestyle interventions in MS subjects are needed in Venezuela to halt the burden of CV disease and diabetes.

Objectives: The present study was designed to evaluate the effect of aqueous extract of Trigonella foenum-graecum(AqE-TFG) seeds on monosodium glutamate (MSG)-induced dyslipidemia and oxidative stress in Wistar rats. Materials and Methods: Neonatal Wistar rats were treated subcutaneously with MSG (4 g/kg b.w.) from day 2 to 14 after birth, on alternate days. After attaining six-weeks of age, MSG-treated rats were administered with AqE-TFG (0.5 and 1 g/kg b.w., orally) or orlistat (10 mg/kg b.w., orally) for 28 days, respectively. Serum chemistry and relevant enzymes in hepato-cardiac tissues were assessed on day 29. Results: AqE-TFG produced significant reduction in serum total cholesterol (TC), triglycerides (TGs), lactate dehydrogenase (LDH), aspartate amino transferase (AST), alanine amino transferase (ALT), hepatic and cardiac lipid peroxides (MDA) levels and elevation in serum high density lipoprotein cholesterol (HDL-C), hepatic and cardiac antioxidant enzymes [glutathione (GSH), and superoxide dismutase (SOD) and catalase (CAT)] levels. Conclusion: Results were comparable with orlistat, a standard anti-obesity drug, and provide clear evidence that the AqE-TFG treatment offered significant protection against MSG-induced dyslipidemia and oxidative stress, and may play an important role in amelioration of the free radical generated consequences like dyslipidemia and atherosclerosis.

We evaluated the effects of grape consumption on inflammation and oxidation in the presence or absence of dyslipidemias in metabolic syndrome (MetS). Men with MetS (n = 24), 11 with high triglycerides and low HDL and 13 with no dyslipidemia were recruited and randomly allocated to consume daily either 46 g of lyophilized grape powder (GRAPE), equivalent to 252 g fresh grapes, or placebo with an identical macronutrient composition and caloric value as GRAPE for four weeks. After a three-week washout, participants followed the alternate treatment. We measured changes between placebo and GRAPE periods in inflammatory and oxidative stress markers both in circulation and in gene expression. Changes in plasma adiponectin (p < 0.05), interleukin (IL)-10 (p < 0.005) and in mRNA expression of the inducible isoform of nitric oxide synthase (iNOS) (p < 0.25) were increased in the GRAPE compared to the placebo period only in those individuals without dyslipidemia. Additionally, plasma IL-10 was negatively correlated with NOX2 expression, a marker of oxidative stress (r = −0.55, p < 0.01), while iNOS expression was positively correlated with the expression of superoxide dismutase 2 (r = 0.642, p < 0.01), a key anti-oxidative enzyme. Grape consumption displayed anti-oxidative and increased anti-inflammatory markers in the absence of the inflammatory milieu associated with dyslipidemias. PMID:23222963

Previous studies have shown that both severe mental disorders (schizophrenia and bipolar disorder) and atopic diseases were associated with an increased risk of metabolic syndrome. However, the role of atopy/the predisposition for allergies in the development of metabolic syndrome is still unknown among those with severe mental disorders. Using the Taiwan National Health Insurance Research Database, 5826 patients with schizophrenia or bipolar disorder (1908 with a predisposition for allergies and 3918 without) were enrolled between 1998 and 2008. Those who developed hypertension, dyslipidemia, and/or diabetes mellitus were identified during the follow-up to the end of 2011. A predisposition for allergies increased the risk of developing hypertension (HR: 1.67), dyslipidemia (HR: 1.82), and diabetes mellitus (HR: 1.37) in later life among those with severe mental disorders. A dose-dependent relationship was noted between having more atopic comorbidities and a greater likelihood of hypertension (1 atopic disease: HR: 1.60; ≧ 2 atopic comorbidities: HR: 1.87), dyslipidemia (HR: 1.73; HR: 2.12), and diabetes mellitus (HR: 1.26; HR: 1.69). A predisposition for allergies was an independent risk factor for hypertension, dyslipidemia, and diabetes mellitus among patients with schizophrenia or bipolar disorder. Further studies would be required to elucidate the underlying pathophysiology among atopy, schizophrenia, bipolar disorder, and metabolic syndrome. Copyright © 2014 Elsevier B.V.

Involvement of toll-like receptor 2 and 4 in association between dyslipidemia and osteoclast differentiation in apolipoprotein E deficient rat periodontium

PubMed Central

2013-01-01

Background Dyslipidemia increases circulating levels of oxidized low-density lipoprotein (OxLDL) and this may induce alveolar bone loss through toll-like receptor (TLR) 2 and 4. The purpose of this study was to investigate the effects of dyslipidemia on osteoclast differentiation associated with TLR2 and TLR4 in periodontal tissues using a rat dyslipidemia (apolipoprotein E deficient) model. Methods Levels of plasma OxLDL, and the cholesterol and phospholipid profiles in plasma lipoproteins were compared between apolipoprotein E-deficient rats (16-week-old males) and wild-type (control) rats. In the periodontal tissue, we evaluated the changes in TLR2, TLR4, receptor activator of nuclear factor kappa B ligand (RANKL) and tartrate resistant acid phosphatase (TRAP) expression. Results Apolipoprotein E-deficient rats showed higher plasma levels of OxLDL than control rats (p<0.05), with higher plasma levels of total cholesterol (p<0.05) and LDL-cholesterol (p<0.05) and lower plasma levels of high-density lipoprotein cholesterol (p<0.05). Their periodontal tissue also exhibited a higher ratio of RANKL-positive cells and a higher number of TRAP-positive osteoclasts than control rats (p<0.05). Furthermore, periodontal gene expression of TLR2, TLR4 and RANKL was higher in apolipoprotein E-deficient rats than in control rats (p<0.05). Conclusion These findings underscore the important role for TLR2 and TLR4 in mediating the osteoclast differentiation on alveolar bone response to dyslipidemia. PMID:23295061

Cardiovascular disease (CVD) is the major cause of morbidity and mortality worldwide. Anacetrapib may be a new treatment option that has a cardiovascular benefit for the management of dyslipidemia. The aim of our current study was to perform a systematic review and meta-analysis of all randomized controlled trials (RCTs) assessing the effect and safety of anacetrapib in the treatment of dyslipidemia. We systematically searched PubMed, Embase, and Cochrane Library database from their inception to 5 October 2017, with the terms: 'anacetrapib' and 'placebo'. From 287 initial citations, 10 studies including 34781 patients with dyslipidemia were included in the final systematic review and meta-analysis. Pooled results showed that anacetrapib significantly increased high density lipoprotein cholesterol (HDL-C) [weighted mean differences (WMD) 53.07, 95% confidence interval (95% CI) 46.79 to 59.36] and apolipoprotein AI (ApoAI) (WMD 53.44, 95% CI 45.72 to 61.16). Our study also showed that anacetrapib significantly reduced low density lipoprotein cholesterol (LDL-C) (WMD -32.99; 95% CI -37.13 to -28.86), Non-HDL-C (WMD -39.19; 95% CI -52.22 to -26.16), triglycerides (TG) (WMD -9.97; 95% CI -10.54 to -9.41), apolipoprotein B (ApoB) (WMD -22.55; 95% CI -28.56 to -16.54) and lipoprotein a [LP(a)] (WMD -13.35; 95% CI -18.31 to -8.39). Our results demonstrated that there was no significant difference in all the following adverse events between the anacetrapib group and placebo group: [hepato-toxicity (OR 0.90, 95% CI: 0.75 to 1.07); musculoskeletal injury (OR 1.01, 95% CI: 0.88 to 1.15); drug-related adverse event (OR 1.00, 95% CI: 0.96 to 1.05); drug-related withdrawn (OR 1.01, 95% CI: 0.95 to 1.08)]. Although further studies are needed, our findings clearly offer support to the use of anacetrapib in the clinical management of patients with dyslipidemia.

Dyslipidemia is reported in 27 - 43% of children and adolescents with overweight/obesity and tracks into adulthood, increasing the risk of cardiovascular morbidity. Cut-off values for fasting plasma lipid concentrations are typically set at fixed levels throughout childhood. The objective of this cross-sectional study was to generate fasting plasma lipid references for a Danish/North-European White population-based cohort of children and adolescents, and investigate the prevalence of dyslipidemia in this cohort as well as in a cohort with overweight/obesity. A population-based cohort of 2141 (1275 girls) children and adolescents aged 6 - 19 (median 11.5) years was recruited from 11 municipalities in Denmark. Additionally, a cohort of children and adolescents of 1421 (774 girls) with overweight/obesity aged 6 - 19 years (median 11.8) was recruited for the study. Height, weight, and fasting plasma lipid concentrations were measured on all participants. Smoothed reference curves and percentiles were generated using the Generalized Additive Models for Location Scale and Shape package in the statistical software R. In the population-based cohort, plasma concentrations of total cholesterol (TC) (P < 0.05), low-density lipoprotein cholesterol (LDL) (P < 0.005), and high-density lipoprotein cholesterol (HDL) (P < 0.005) were higher in the youngest compared to the oldest tertile. Fasting plasma levels of triglycerides (TG) (P < 0.005) increased with age in both sexes. In boys, non-HDL was lower in the oldest compared to the youngest tertile (P < 0.0005). Concentrations of TC, LDL, non-HDL, and TG were higher (P < 0.05), and HDL lower (P < 0.05) in the cohort with overweight/obesity in both sexes and for all ages except for TC in the youngest girls. The overall prevalence of dyslipidemia was 6.4% in the population-based cohort and 28.0% in the cohort with overweight/obesity.

Blood concentrations of total cholesterol, cholesterol of very high density lipoproteins (alpha-cholesterol), triglycerides, beta-lipoproteins and 11-hydroxycorticosteroids were studied in 560 patients with rectal, colon, lung, ovarian, breast and endometrial cancer as well as in 238 controls. Patients with breast and rectal cancer were examined before and repeatedly after operation (every 6-12 months within 4-5 years). The blood concentration of total cholesterol was found to be elevated in breast cancer patients and controls with fibroadenomatosis and decreased in females with ovarian cancer and males with lung cancer. The level of blood alpha-cholesterol was decreased in males with all tumor localizations under study and in females with ovarian and rectal cancer. The concentration of triglycerides was increased in women patients only. Three possible causes of dyslipidemia in cancer patients are discussed: its development before tumor manifestation, the effect of tumor on the metabolic status of the host and the role of emotional stress in the increase of triglycerides level in the blood of primary cancer patients.

The observed reduction in macrovascular outcomes in the United Kingdom Progressive Diabetes Study (UKPDS) trial in patients with type 2 diabetes mellitus (DM), treated intensively with insulin or sulfonylureas, was of borderline significance (p = 0.052). This may be because of the role of factors other than glycemic control in the etiology of macrovascular disease. The UKPDS and other studies have suggested that lipid parameters are potent predictors of adverse outcomes in patients with type 2 DM. In patients with DM, dyslipidemia is characterized by elevated serum triglycerides and low high density lipoprotein-cholesterol (HDL-C) with normal total serum cholesterol levels and usually accompanied by an elevation of atherogenic, small, dense low density lipoprotein-cholesterol (LDL-C) particles. Dyslipidemia is only partly corrected by dietary and lifestyle modifications and pharmacological glycemic control in patients with DM. Several guidelines, including those published by the New Zealand Heart Foundation, suggest that lipid-modifying therapies are appropriate in patients considered to be at high or very high risk of a cardiac event. This includes patients with established vascular disease. Some recent studies suggest that patients with type 2 DM have risk comparable to patients without DM, but have experienced previous myocardial infarction (MI). Subgroup analysis of trials including the Scandinavian Simvastatin Survival Study (4S) and Cholesterol and Recurrent Events (CARE), which included patients with DM, have shown a significant reduction in adverse outcomes, although many patients with DM and dyslipidemia were excluded. Of lipid-lowering drugs, fibric acid derivatives are probably the most appropriate for patients with DM and dyslipidemia and their role is being evaluated in large, long-term outcome studies such as Fenofibrate Intervention and Event Lowering in Diabetes (FIELD).

Purpose to compare cut off points corrected for age and gender (COOP) with fixed cut off points (FCOP) for fasting plasma insulin and Homeostatic model assessment-insulin resistance (HOMA-IR) for the diagnosis of IR in obese children and adolescents and their correlation with dyslipidemia. Methods A multicenter, cross-sectional study including 383 subjects aged 7 to 18 years, evaluating fasting blood glucose, plasma insulin, and lipid profile. Subjects with high insulin levels and/or HOMA-IR were considered as having IR, based on two defining criteria: FCOP or CCOP. The frequency of metabolic abnormalities, the presence of IR, and the presence of dyslipidemia in relation to FCOP or CCOP were analyzed using Fisher and Mann-Whitney exact tests. Results Using HOMA-IR, IR was diagnosed in 155 (40.5%) and 215 (56.1%) patients and, using fasting insulin, 150 (39.2%) and 221 (57.7%), respectively applying FCOP and CCOP. The use of CCOP resulted in lower insulin and HOMA-IR values than FCOP. Dyslipidemia was not related to FCOP or CCOP. Blood glucose remained within normal limits in all patients with IR. There was no difference in the frequency of IR identified by plasma insulin or HOMA-IR, both for FCOP and CCOP. Conclusion The CCOP of plasma insulin or of HOMA-IR detected more cases of IR as compared to the FCOP, but were not associated with the frequency of dyslipidemia. As blood glucose has almost no fluctuation in this age group, even in the presence of IR, fasting plasma insulin detected the same cases of IR that would be detected by HOMA-IR. PMID:29383306

Despite the importance of identifying and screening dyslipidemia to prevent coronary artery diseases CAD(Coronary Artery Disease), little information is available on dyslipidemia in our large area. So the present study aimed to assess the management status of lipid abnormalities and its association with other CAD risk factors in an urban population of southeast of Iran. This cross-sectional study was a part of the Kerman coronary artery disease risk factor study KERCADRS (Kerman coronary artery disease risk study) as a population-based, epidemiological research among 5900 individuals aged 15 to 75 years who were residents of Kerman city, the largest city in Southeast of Iran. Lipid profile was assessed using enzymatic laboratory methods. In total, 5558 persons from 5899 participants were assessed in whom 45.1 % were male and 54.9 % female. Overall 20.9 % had borderline level of cholesterol (200-239 mg/dl) and 8.7 % suffered from hypercholesterolemia (≥240 mg/dl). The prevalence of undiagnosed dyslipidemia (UDL) was 16.8 % and of diagnosed dyslipidemia (DDL) was 13.2 % that both UDL and DDL were more prevalent in women. Also, UDL was more revealed in third and fourth age decades. Advanced age, anxiety, obesity (BMI ≥30 Kg/m 2 ), and family history of dyslipidemia predicted dyslipidemia in study population. The overall prevalence of UDL was higher than of DDL, and was significantly influenced by advanced age, anxiety, obesity, and family history of dyslipidemia. The data showed that our health care management system should improve its strategies to reduce the burden of this important CAD risk factor.

Dyslipidemia and dementia: current epidemiology, genetic evidence and mechanisms behind the associations

The role of cholesterol in the etiology of Alzheimer’s disease (AD) is still controversial. Some studies aiming to explore the association between lipids and/or lipid lowering treatment and AD indicate a harmful effect of dyslipidemia and a beneficial effect of statin therapy on AD risk. The findings are supported by genetic linkage and association studies that have clearly identified several genes involved in cholesterol metabolism or transport as AD susceptibility genes, including Apolipoprotein E (APOE), Apolipoprotein J (APOJ, CLU) and the sortilin-related receptor (SORL1). Functional cell biology studies support a critical involvement of lipid raft cholesterol in the modulation of AbetaPP processing by β- and γ-secretase resulting in altered Aβ production. Contradictory evidence comes from epidemiological studies showing no or controversial association between dyslipidemia and AD risk, cell biology studies suggesting that there is little exchange between circulating and brain cholesterol, that increased membrane cholesterol is protective by inhibiting loss of membrane integrity through amyloid cytotoxicity, and that cellular cholesterol inhibits co-localization of BACE1 and AbetaPP in non-raft membrane domains and thereby increasing generation of plasmin, an Aβ-degrading enzyme. The aim of this review is to summarize the findings of epidemiologic and cell biologic studies aiming to elucidate the role of cholesterol in AD etiology. PMID:21965313

Cardiovascular diseases and dyslipidemia represent a major health issue in psychiatry. Many psychotropic drugs can induce a rapid and substantial increase of blood lipid levels. This study aimed to determine the potential predictive power of an early change of blood lipid levels during psychotropic treatment on long-term change and on dyslipidemia development. Data were obtained from a prospective study including 181 psychiatric patients with metabolic parameters monitored during the first year of treatment and with adherence ascertained. Blood lipid levels (ie, total cholesterol [TC], low-density lipoprotein cholesterol [LDL-C], high-density lipoprotein cholesterol [HDL-C], non-high-density lipoprotein cholesterol [non-HDL-C], and fasting triglycerides [TGs]) were measured at baseline and after 1, 3, and/or 12 months of treatment. Receiver-operating characteristic analyses indicated that early (ie, after 1 month of psychotropic treatment) increases (≥5%) for TC, LDL-C, TG, and non-HDL-C and decrease (≥5%) for HDL-C were the best predictors for clinically relevant modifications of blood lipid levels after 3 months of treatment (≥30% TC, ≥40% LDL-C, ≥45% TG, ≥55% non-HDL-C increase, and ≥20% HDL-C decrease; sensitivity 70%-100%, specificity 53%-72%). Predictive powers of these models were confirmed by fitting longitudinal multivariate models in the same cohort (P ≤ .03) as well as in a replication cohort (n = 79; P ≤ .003). Survival models showed significantly higher incidences of new onset dyslipidemia (TC, LDL-C, and non-HDL-C hypercholesterolemia, HDL-C hypocholesterolemia, and hypertriglyceridemia) for patients with early changes of blood lipid levels compared to others (P ≤ .01). Early modifications of blood lipid levels following prescription of psychotropic drugs inducing dyslipidemia should therefore raise questions on clinical strategies to control long-term dyslipidemia.

Introduction: Newfoundland and Labrador (NL) has the highest prevalence of cardiovascular disease (CVD) in Canada. Dyslipidemia is a risk factor for CVD. This study compares the prevalence of dyslipidemia in the NL population with the rest of Canada. Methods: A cross-sectional study, using data from the Canadian Primary Care Sentinel Surveillance Network (CPCSSN), was undertaken. The study population included adults, excluding pregnant women, aged 20 years and older. Canadian guidelines were used for classifying dyslipidemia. Univariate and multivariate analyses were conducted to compare the lipid levels and prevalence of dyslipidemia between NL and the rest of Canada. Results: About 128,825 individuals (NL: 7,772; rest of Canada: 121,053) were identified with a mean age of 59 years (55% females). Mean levels of total cholesterol (4.96 vs. 4.93, p = 0.03), low-density lipoprotein (LDL) (3.00 vs. 2.90 mmol/L, p < 0.0001), triglyceride (1.47 vs. 1.41 mmol/L, p < 0.0001), and high-density lipoprotein (HDL) (1.29 vs. 1.39 mmol/L, p < 0.0001) were significantly different in NL compared to the rest of Canada. Dyslipidemias of LDL (29 vs. 25% p < 0.0001), HDL (38 vs. 27%, p < 0.0001), and triglyceride (29 vs. 26%, p < 0.0001) were significantly more common in NL. After adjustment for confounding variables, NL inhabitants were more likely to have dyslipidemia of total cholesterol (OR: 1.16, 95% CI: 1.10–1.23, p < 0.0001), HDL (OR: 1.52, 95% CI: 1.44–1.60, p < 0.0001), LDL (OR: 1.38, 95% CI: 1.30–1.46, p < 0.0001), and ratio (OR: 1.53, 95% CI: 1.42–1.60, p < 0.0001). Conclusion: The NL population has a significantly higher rate of dyslipidemia compared to the rest of Canada, and the mean levels of all lipid components are worse in NL. Distinct cultural and genetic features of the NL population may explain this, accounting for a higher rate of CVD in NL. PMID:26664873

Studies to explore the relationship between self-reported snoring and dyslipidemia, especially high total cholesterol (TC) and high low-density lipoprotein cholesterol (LDL-C), in the general population are still lacking. Our study was designed to examine whether self-reported snoring is significantly associated with dyslipidemia and ascertain the effects of different snoring intensities on dyslipidemia. There were 10,139 participants in our study. After adjustment for all confounding factors, self-reported snoring (OR = 1.207; p = 0.003), moderate (OR = 1.229; p = 0.015), strong (OR = 1.222; p = 0.033), and very strong (OR = 1.467; p = 0.012) snoring intensity, but not low (OR = 1.110; p = 0.224) snoring intensity, were significantly associated with dyslipidemia among adults with BMI (body mass index) ≥ 25 kg/m². In addition, self-reported snoring was significantly associated with high TC (OR = 1.167; p = 0.048) and high LDL-C (OR = 1.228; p = 0.044), rather than low HDL-C (OR = 1.171; p = 0.057) and high triglyceride (TG) (OR = 1.110; p = 0.141). In conclusion, adults with BMI ≥ 25 kg/m² and who experience snoring, especially moderate, strong, and very strong intensity levels of snoring, should be on the alert regarding the possibility of dyslipidemia, especially high LDL-C and high TC.

Multifactorial dyslipidemia, characterized by elevated total cholesterol (TC) or low-density lipoprotein cholesterol (LDL-C), is associated with dyslipidemia and markers of atherosclerosis in young adulthood. Screening for dyslipidemia in childhood could delay or reduce cardiovascular events in adulthood. To systematically review the evidence on benefits and harms of screening adolescents and children for multifactorial dyslipidemia for the US Preventive Services Task Force (USPSTF). MEDLINE, Cochrane Central Register of Controlled Trials, and PubMed were searched for studies published between January 1, 2005, and June 2, 2015; studies included in a previous USPSTF evidence report and reference lists of relevant studies and ongoing trials were also searched. Surveillance was conducted through April 9, 2016. Fair- and good-quality studies in English with participants 0 to 20 years of age. Two investigators independently reviewed abstracts and full-text articles and extracted data into evidence tables. Results were qualitatively summarized. Outcomes included dyslipidemia (TC≥200 mg/dL or LDL-C≥130 mg/dL) and atherosclerosis in childhood; myocardial infarction and ischemic stroke in adulthood; diagnostic yield (number of confirmed cases per children screened); and harms of screening or treatment. Simulated diagnostic yield was calculated as initial screening yield × positive predictive value from a study with confirmatory testing. Screening of children for multifactorial dyslipidemia has not been evaluated in randomized clinical trials. Based on 1 observational study (n = 6500) and nationally representative prevalence estimates, the simulated diagnostic yield of screening for elevated TC varies between 4.8% and 12.3% (higher in obese children [12.3%] and at the ages when TC naturally peaks-7.2% at age 9-11 years and 7.2% at age 16-19 years). One good-quality randomized clinical trial (n = 663) found a modest effect of intensive dietary counseling for

The incidence and the magnitude of lipodystrophy and dyslipidemia in HIV-treated people reported in previous studies are very variable. Several predisposing factors have been identified, but there are few data on genetic factors. To search for a correlation between APOC3 polymorphisms and lipid disorders and lipodystrophy in HIV patients under d4T and protease inhibitors (PI)-containing HAART, we designed a monocenter, cross-sectional study in a University Hospital in Southern France during the period 2001-2004. Forty patients under HAART were included, with d4T for > or = 2 years and PI for > or = 1 year. We determined body mass composition by DXA, lipoprotein markers, and the -455/-482 apo C3 genotypes. Carriers of APOC3 variant alleles (-455 1/-482 1) displayed higher levels of triglycerides (3.72 vs. 2.57 mmol/liter), apo C3 (45.3 vs. 34.5 mg/liter), and apo E (130.2 vs. 66.5 mg/liter) and a lower fat mass (13.9 vs. 19.7%) than patients with nonvariant alleles (-455 0/-482 0). APOC3 polymorphisms might be associated with both dyslipidemia and lipoatrophy in HAART-treated patients.

Antiretroviral drugs increase biosynthesis and reduce hepatic clearance of serum cholesterol. It is thus important to evaluate the impact of antiretroviral treatment on serum lipoprotein levels and the risk of dyslipidemia. We searched EMBASE and PubMed for articles comparing lipid profiles between HIV-infected adult patients naïve and exposed to antiretroviral therapy (ART). Eligible studies were pooled by performing random-effects meta-analyses of mean serum lipoprotein levels and prevalence estimates of dyslipidemias. 51 observational studies comprising 37,110 patients were included in the meta-analyses. ART-exposed patients had significantly higher concentrations of total cholesterol (45 studies, mean difference [MD]=29.4mg/dL, 95% confidence interval [CI] 26.5 to 32.4, I(2)=82.2%), low density lipoprotein-cholesterol (37 studies, MD=14.9mg/dL, 95% CI 11.2 to 18.5, I(2)=86.1%), and triglycerides (43 studies, MD=46.8mg/dL, 95% CI 37.8 to 55.8, I(2)=97.1%), compared with ART-naïve patients. The risks of hypercholesterolemia (25 studies, pooled odds ratio [OR] 3.8, 95% CI 3.1 to 4.7, I(2)=60.0%) and hypertriglyceridemia (21 studies, OR 2.2, 95% CI 1.7 to 2.9, I(2)=81.7%) were also significantly higher among ART-exposed patients, compared with ART-naïve patients. Antiretroviral therapy is significantly associated with increase in serum lipid levels and increased risk of dyslipidemia. Whether or not these associations are causal should be investigated by future studies. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

The precursors of atherogenic dyslipidemia (AD) are not well defined. Therefore, we investigated 62 non-obese, non-diabetic AD and 221 normolipemic children. Anthropometric parameters, blood pressure and biochemical measures were obtained in index children, their parents and all available siblings. The heritability (h(2)) of anthropometric and biochemical traits was estimated by SOLAR. Rare and common variants in APOA1 and LPL genes were screened by re-sequencing. Compared to normolipemic, AD children showed increased body mass index, waist circumference, plasma glucose, insulin, ApoB, HOMA-IR, hs-CRP and lower adiponectin (p<0.001 for all). Metabolic syndrome was present in 40% of AD while absent in controls. All traits (except adiponectin and hs-CRP) showed a strong familial aggregation, with plasma glucose having the highest heritability (89%). Overall, 4 LPL loss-of-function mutations were detected (p.Asp9Asn, p.Ser45Asn, p.Asn291Ser, p.Leu365Val) and their cumulative prevalence was higher in AD than in control children (0.073 vs. 0.026; P=0.038). The LPL p.S447* gain-of-function mutation, resulted to be less frequent in AD than in control children (0.064 vs. 0.126; P=0.082). No variant in the APOA1 gene was found. Our data indicate that AD is a rather common dyslipidemia in childhood; it associates with metabolic abnormalities typical of insulin resistant state and shows a strong familial aggregation. LPL variants may contribute to the development of AD phenotype.

The aim of this study was to explore the potency of salacca vinegar made from various Indonesian salacca fruit extracts as therapeutic agent for hyperglycemia and dyslipidemia for STZ-induced diabetic rats. The rats were grouped into untreated rats, STZ-induced diabetic rats without treatment, and STZ-induced diabetic rats treated with Pondoh salacca vinegar, Swaru salacca vinegar, Gula Pasir salacca vinegar, Madu salacca vinegar, or Madura salacca vinegar. Parameter observed included blood glucose, total cholesterol (TC), high density lipoprotein (HDL), low density lipoprotein (LDL), triglyceride (TG), malondialdehyde (MDA), superoxide dismutase (SOD), and pancreas histopathology of the samples. The results demonstrated that all salacca vinegars were capable of reducing blood sugar (from 25.1 to 62%) and reducing LDL (from 9.5 to 14.8 mg/dL), TG (from 58.3 to 69.5 mg/dL), MDA (from 1.1 to 2.2 mg/dL), and TC (from 56.3 to 70.5 mg/dL) as well as increasing HDL blood sugar of STZ-induced diabetic Wistar rats (from 52.3 to 60 mg/dL). Various salacca vinegars were also capable of regenerating pancreatic cells. Nevertheless, the ability of Swaru salacca vinegar to manage hyperglycemia and dyslipidemia appeared to be superior to other salacca vinegars. Swaru salacca vinegar is a potential therapeutic agent to manage hyperglycemia and dyslipidemia of STZ-induced diabetic rats. PMID:28424779

Chronic kidney disease (CKD) has been defined as a coronary artery disease risk equivalent. Therefore, the current guideline has been recommended for CKD patients to reach and maintain a low-density lipoprotein-cholesterol (LDL-C) goal of less than 100 mg/dL. However, the data regarding the achievement of LDL-C goal in these patients is lacking. This study was conducted to evaluate the types of dyslipidemia affecting patients with CKD stages 3 and 4 and to determine whether these patients achieved LDL-C goal. We performed a retrospective chart review of patients with CKD stage 3 or 4 and dyslipidemia who were followed-up at Siriraj Hospital between October 2011 and September 2012. In total, 150 patients with CKD stage 3 or 4 and dyslipidemia were recruited. The mean age was 72±10 years, and the body mass index was 25.6±4 kg/m(2); 60% had CKD stage 3 with an estimated glomerular filtration rate of 34±12 mL/min/1.73 m(2), and 54% had type 2 diabetes. The percentage of patients with hypercholesterolemia was 78%, hypertriglyceridemia 54%, and low high-density lipoprotein-C 36%. Of these, 52% had mixed hyperlipidemia. Statin treatment was prescribed to 87% of the patients, of which only 31.3% achieved the LDL-C goal according to the National Cholesterol Education Program and the European Society of Cardiology/European Atherosclerosis Society recommendations. Patients who did not achieve the LDL-C goal had a higher cholesterol level at diagnosis and higher prevalence of type 2 diabetes and stroke than those who achieved it. Two-thirds of CKD patients with hyperlipidemia had mixed hyperlipidemia. Despite the high frequency of statin treatment, only one-third of patients with CKD achieved the LDL-C goal. Thus, a developmental plan for the management of dyslipidemia in patients with CKD should be implemented to increase their achievement of the LDL-C goal.

Dyslipidemias are common in HIV-infected children, especially if treated with protease inhibitors, but there are few data on how to treat dyslipidemias in this population. We estimated the dyslipidemia prevalence and its association with treatment, diet and physical exercise in children on antiretroviral treatment at the El Salvador reference center for pediatric HIV care (CENID). Information was gathered regarding socio-demographic characteristics, treatment, diet and physical activity of 173 children aged 5-18 years and receiving antiretroviral therapy. Triglycerides, total cholesterol, low-density lipoprotein (LDL-C), high-density lipoprotein (HDL-C), viral load and CD4 T-lymphocytes were measured. Abnormal concentrations were defined as triglycerides ≥130 mg/dL in 10- to 18-year olds and ≥100 mg/dL in <10-year olds; total cholesterol ≥200 mg/dL; LDL-C ≥130 mg/dL and HDL-C ≤35 mg/dL. We adjusted 4 different multivariate models to assess the independent association of each type of dyslipidemia with protease inhibitors, diet and physical exercise. Of the 173 children, 83 (48%) had hypertriglyceridemia and 25 (14.5%) hypercholesterolemia. High LDL-C concentrations were observed in 17 children (9.8%) and low HDL-C in 38 (22%). Treatment with protease inhibitors was significantly associated with hypertriglyceridemia [prevalence ratio (PR) 2.8; 95% confidence interval (CI): 2.0-3.8] and hypercholesterolemia (PR 9.0; 95% CI: 3.6-22.2). Higher adherence to a "high fat/sugar diet" was associated with hypercholesterolemia (PR 1.6; 95% CI: 1.1-2.3) and high LDL-C (PR 1.7; 95% CI: 1.0-2.9). Compared with those exercising <3 times/week, children exercising ≥7 times were less likely to have low HDL-C (PR = 0.4; 95% CI: 0.2-0.7). These results suggest that a healthy diet and exercise habits can contribute to controlling some aspects of the lipid profile in this population.

Combined dyslipidemia in childhood.

PubMed

Kavey, Rae-Ellen W

2015-01-01

Combined dyslipidemia (CD) is now the predominant dyslipidemic pattern in childhood, characterized by moderate-to-severe elevation in triglycerides and non-high-density lipoprotein cholesterol (non-HDL-C), minimal elevation in low-density lipoprotein cholesterol (LDL-C), and reduced HDL-C. Nuclear magnetic resonance spectroscopy shows that the CD pattern is represented at the lipid subpopulation level as an increase in small, dense LDL and in overall LDL particle number plus a reduction in total HDL-C and large HDL particles, a highly atherogenic pattern. In youth, CD occurs almost exclusively with obesity and is highly prevalent, seen in more than 40% of obese adolescents. CD in childhood predicts pathologic evidence of atherosclerosis and vascular dysfunction in adolescence and young adulthood, and early clinical cardiovascular events in adult life. There is a tight connection between CD, visceral adiposity, insulin resistance, nonalcoholic fatty liver disease, and the metabolic syndrome, suggesting an integrated pathophysiological response to excessive weight gain. Weight loss, changes in dietary composition, and increases in physical activity have all been shown to improve CD significantly in children and adolescents in short-term studies. Most importantly, even small amounts of weight loss are associated with significant decreases in triglyceride levels and increases in HDL-C levels with improvement in lipid subpopulations. Diet change focused on limitation of simple carbohydrate intake with specific elimination of all sugar-sweetened beverages is very effective. Evidence-based recommendations for initiating diet and activity change are provided. Rarely, drug therapy is needed, and the evidence for drug treatment of CD in childhood is reviewed.

The prevalence of dyslipidemia and overweight is significantly higher in aircrews than that in general population. The purpose of the study was to examine the distribution of APOE gene polymorphism and the influence of which as well as occupational environment on dyslipidemia and overweight in Chinese civil aircrews. APOE gene polymorphism was investigated using PCR-RFLP, plasma lipid parameters were measured by standard enzymatic kits and personal information of the aircrews was collected through questionnaires. The allele frequencies among aircrews were ε2: 17.0%, ε3: 80.9%, and ε4: 2.1%, APOE gene polymorphism was associated with significant differences in TC and LDL-C. E2 individuals had the lowest TC and LDL-C concentrations, and E4 participants had the highest levels (p<0.001). In addition, the TC and LDL-C concentrations, as well as BMI rose with the increasing cumulative flying hours (p<0.05). The further logistic regression analysis showed the significant associations of BMI and dyslipidemia (p<0.0001, OR=2.093), cumulative flight time and overweight (p<0.0001, OR=1.560). The distribution of APOE alleles among aircrews was provided for the first time, which is not fully identical with that among general population. These data also suggested the cumulative flight time influenced dyslipidemia and overweight as an environmental contributor. Copyright © 2012 Elsevier B.V. All rights reserved.

Previous studies have shown that circulating adipokines may play an important role in the pathogenesis of some obesity related chronic disease such as dyslipidemia and type2 diabetes mellitus. The aim of the present study was to investigate the association between vaspin, omentin-1 and retinol binding protein-4 levels with metabolic dyslipidemia (MD) criteria in obese and non-obese individuals. The study was conducted on 170 obese and 81 non-obese individuals. After collecting the blood samples, serum levels metabolic parameters as well as three circulating adipokines and body composition were measured. No significant difference was noted regarding the mean serum levels of omentin-1 and vaspin between the obese and non-obese groups, while, serum level of RBP4 was significantly higher in the non-obese group. We found the 0.22 increased risk of MD in obese individuals with higher RBP4 concentration. After the adjustment for confounding factors, this association was still significant. No significant association was noted between MD and its components relative risks with omentin-1 and vaspin levels. Our study demonstrated that circulating RBP4 was significantly higher in the obese individuals which may increase the risk of MD in them. Further researches are needed to address this association.

The association of food insecurity with dyslipidemia has not been firmly established. The main objective of this study was to assess whether food insecurity was associated with dyslipidemia. A population-based sample of 1,663 adults from the 2008-2011 Survey of the Health of Wisconsin was used. Food insecurity was defined as an affirmative response to either of the questions: (1) "In the last 12months, have you been concerned about having enough food for you or your family?" (2) "In the last 12months, have your food choices been limited because there wasn't enough money?" High total cholesterol was defined as total cholesterol (TC) >240mg/dL or taking prescribed lipid-lowering medication. Low high-density lipoprotein cholesterol (HDL-C) was defined as <40mg/dL in men and <50mg/dL in women. Food insecurity was not associated with high TC either among men or women. Food insecurity was associated with a higher likelihood of low HDL-C among women (adjusted odds ratio [AOR]: 2.31 {95% confidence interval [CI]: 1.42, 3.76}), but not among men. Obesity appears to be a partial mediator of the association among women (P from the Sobel test=0.01). These findings suggest that food insecurity may contribute to an increased risk of low HDL-C in women. Copyright © 2015 Elsevier Inc. All rights reserved.

Dyslipidemia is caused by disturbances in lipid metabolism that lead to chronic elevations of serum lipids, especially low-density lipoprotein (LDL)-cholesterol and triglycerides, increasing the risk of metabolic syndrome, obesity, diabetes, atherogenic processes, and cardiovascular diseases. The oil from the fruits of Euterpe oleracea (OFEO) is rich in unsaturated fatty acids with potential for treating alterations in lipid metabolism. In this study, we aimed to investigate the effect of OFEO on hyperlipidemia induced by Cocos nucifera L. saturated fat (GSC) in Wistar rats. Chromatographic profile showed that unsaturated fatty acids account for 66.08% in OFEO, predominately oleic acid (54.30%), and saturated fatty acids (palmitic acid 31.6%) account for 33.92%. GSC-induced dyslipidemia resulted in an increase in total cholesterol, LDL-cholesterol, triglycerides, glucose, and liver and abdominal fat, as well as atherogenic processes in the thoracic aorta. OFEO treatment did not reduce hypertriglyceridemia, but did reduce total cholesterol and LDL-cholesterol, thus contributing to the antiatherogenic action of OFEO. OFEO treatment inhibited the formation of atheromatous plaques in the vascular endothelium of the treated rats, as well as those who were treated with simvastatin. The results obtained suggest that OFEO has an antiatherogenic effect in a rat model of dyslipidemia.

The Japan Atherosclerosis Society (JAS) has recommended serum lipid management goals (SLMGs) based on the coronary heart disease (CHD) risk classification included in its 2007 guidelines for the diagnosis and prevention of atherosclerotic cardiovascular disease in the Japanese population (JAS GL 2007). The Japan Society of Ningen Dock created a database of subjects receiving annual health examinations at 21 institutes nationwide. Using this database, we evaluated the efficacy of current treatment for patients with dyslipidemia by identifying risk factors for CHD development, based on the JAS recommendations. This multicenter, retrospective study was conducted using data obtained from 21 institutions across Japan. 17,991 adults taking dyslipidemia medications were enrolled. The JAS GL 2007 was used for evaluation. Since the guideline indicated separate goals (secondary prevention for subjects with a prior history of CHD and primary prevention for those with other CHD risk factors), we evaluated the percentages of goals met. The serum low-density lipoprotein cholesterol (LDL-C) levels were calculated using the Friedewald formula. The LDL-C level was measured using a direct homogeneous assay if the triglycerides (TG) level was 400 mg/dL or higher. The achievement rates of the SLMGs were as follows: LDL-C, 72.3%; high-density lipoprotein cholesterol (HDL-C), 94.6%; and TG, 69.7%. Our results regarding Japanese patients receiving dyslipidemia treatment for CHD prevention identified insufficient reductions in the levels of LDL-C and TG in those at high risk for CHD and suggest the need for more aggressive lipid-lowering therapy.

In the present study, we examined retinal vascular oxygen saturation in patients with retinal vein occlusion (RVO), high blood pressure (HBP) and dyslipidemia, before and during intravitreal vascular endothelial growth factor (VEGF) injection (ranibizumab). We retrospectively reviewed the medical records of six patients with visual acuity (VA) reduced by macular edema (ME) secondary to RVO with HBP and dyslipidemia, who underwent intravitreal anti-VEGF injection between October 2014 and February 2015 in the department of ophthalmology of François-Quesnay Hospital at Mantes-la-Jolie (France). The main inclusion criterion was the presence of RVO with ME and decreased VA. The primary endpoint was improvement of retinal venous oxygen saturation in patients with RVO before and 3 months after intravitreal ranibizumab injection. Secondary outcomes were improvement of retinal arterial oxygen saturation, improvement of best-corrected visual acuity (BCVA) on the Early Treatment Diabetic Retinopathy Study (ETDRS) scale, regression of ME measured by the central macular thickness (CMT) in nm and studying the correlation between blood pressure (BP) and retinal venous oxygen saturation before and after ranibizumab. Six eyes of six patients were included. Before treatment, the mean (standard deviation [SD]) of the retinal venous saturation (%) was 38.1±14.2. Three months after the injections, the mean (SD) of the retinal venous saturation (%) increased statistically significantly 49.2±11 (P=0.03). In this study, retinal venous oxygen saturation in patients with RVO, HBP and dyslipidemia was partially normalized during intravitreal ranibizumab treatment. Copyright © 2016 Elsevier Masson SAS.

Recent epidemiological evidences indicate close association between inorganic arsenic exposure via drinking water and cardiovascular diseases. However, the exact mechanism of this arsenic-mediated increase in cardiovascular risk factors remains enigmatic. In order to investigate the effects of inorganic arsenic exposure on lipid metabolism, male albino rats were exposed to 50, 100 and 150 ppm arsenic as sodium arsenite and 100, 150 and 200 ppm arsenic as sodium arsenate respectively in their drinking water for 12 weeks. Dyslipidemia induced by the two arsenicals exhibited different patterns. Hypocholesterolemia characterised the effect of arsenite at all the doses, but arsenate induced hypercholesterolemia at the 150 ppm As dose. Hypertriglyceridemia was the hallmark of arsenate effect whereas plasma free fatty acids (FFAs) was increased by the two arsenicals. Reverse cholesterol transport was inhibited by the two arsenicals as evidenced by decreased HDL cholesterol concentrations whereas hepatic cholesterol was increased by arsenite (100 ppm As), but decreased by arsenite (150 ppm As) and arsenate (100 ppm As) respectively. Brain cholesterol and triglyceride were decreased by the two arsenicals; arsenate decreased the renal content of cholesterol, but increased renal content of triglyceride. Arsenite, on the other hand, increased the renal contents of the two lipids. The two arsenicals induced phospholipidosis in the spleen. Arsenite (150 ppm As) and arsenate (100 ppm As) inhibited hepatic HMG CoA reductase. At other doses of the two arsenicals, hepatic activity of the enzyme was up-regulated. The two arsenicals however up-regulated the activity of the brain enzyme. We observed positive associations between tissue arsenic levels and plasma FFA and negative associations between tissue arsenic levels and HDL cholesterol. Our findings indicate that even though sub-chronic exposure to arsenite and arsenate through drinking water produced different patterns of

The clinical inertia in the screening and treatment of patients at high or very high cardiovascular risk leads to the failure to achieve LDLc targets in this population. The aim of the DIANA study was to determine the opinion of doctors about the screening for dyslipidaemia, the usual practice, and the differences between Primary Care physicians and other specialties. A questionnaire, using the modified Delphi method, included four blocks on dyslipidemic patients with impaired glucose metabolism. Of the 497 participating experts, 58% were Primary Care physicians. There was agreement on the need for dyslipidemia screening in patients with diabetes, ischaemic heart disease or hypertension, although to a lesser extent among Primary Care physicians. Greater significant differences were found in situations such as pre-diabetes or family history of premature cardiovascular disease (86.2% and 88.6% in Primary Care physicians versus 96.1% and 97.6% in other specialties, respectively). There was no agreement on the need for screening in the presence of xanthomas, xanthelasmas or corneal arcus in people under the age of 45 years, with statistically significant differences in the latter. Dyslipidaemia screening is mainly performed on patients with cardiovascular disease or any major cardiovascular risk factor, and cutaneous lesions of familial hypercholesterolaemia are underestimated. The need for accurate screening and treatment of dyslipidemia in subjects at high cardiovascular risk must be stressed. Copyright © 2016 Sociedad Española de Médicos de Atención Primaria (SEMERGEN).

Increasing studies have shown that dyslipidemia and inflammatory responses play important roles in the progression of microvascular diabetic complications. Esculin (ES), a coumarin derivative, was extracted from Fraxinus rhynchophylla. The present study was to evaluate the potential effects of ES on lipid metabolism, inflammation responses and renal damage in streptozotocin (STZ)-induced experimental diabetic rats and explore the possible mechanism. Diabetic rat model was established by administration high-glucose-fat diet and intraperitoneal injection of STZ 45 mg/kg. ES was administrated to diabetic rats intragastrically at 10, 30 and 90 mg/kg for 10 weeks respectively. The levels of triglycerides (TG), total cholesterol (T-CHO), low density lipoproteins (LDL), and high-density-cholesterol (HDL-C) in serum were measured. IL-1, IL-6, ICAM-1, NO, NAGL, and AGEs level in serum were detected by ELISA assay. The accumulation of AGEs in kidney tissue was examined by immunohistochemistry assay. The results showed that ES could decrease TG, T-CHO, LDL levels in serum of diabetic rats in a dose dependent manner. ES also decreased IL-1, IL-6, ICAM-1, NO and NGAL levels in serum of diabetic rats in a dose dependent manner. Furthermore, ES at 30 and 90 mg/kg significantly decreased AGEs level in serum and alleviated AGEs accumulation in renal in diabetic rats. Our findings indicate that ES could improve dyslipidemia, inflammation responses, renal damage in STZ-induced diabetic rats and the possible mechanism might be associated with the inhibition of AGEs formation.

Even with improvements in lifestyle interventions, better control of cardiovascular (CV) risk factors, and improvements in CV outcomes, cardiovascular disease (CVD) remains the leading cause of morbidity and mortality in Portugal and Europe. Atherogenic dyslipidemias, particularly hypercholesterolemia, have a crucial causal role in the development of atherosclerotic CVD. The clinical approach to a patient with dyslipidemia requires an accurate diagnosis, based on harmonized and standardized lipid and lipoprotein laboratory assessments. Results and reports of these tests, together with assessment of total CV risk and the respective therapeutic targets, will help ensure that clinical guidelines and good clinical practices are followed, increasing the reliability of screening for lipid disorders, producing more accurate diagnoses and CV risk stratification, and improving CV prevention. To this end, this consensus aims to provide clinicians with practical guidance for the harmonization and standardization of laboratory lipid tests, focusing on the most recent dyslipidemia management guidelines.

In Spain, where cardiovascular disease (CVD) is the leading cause of death, hypercholesterolemia, one of the most prevalent risk factors in adults, is poorly controlled. Dyslipidemia should not be approached in isolation, but in the context of overall cardiovascular risk (CVR). Measurement of CVR facilitates decision making, but should not be the only tool nor should it take the place of clinical judgment, given the limitations of the available calculation methods. This document, prepared by the Interdisciplinary Spanish Committee on Cardiovascular Prevention, at the proposal of the Spanish Society of Arteriosclerosis, reviews the cardiovascular prevention activities of the regional health authorities, scientific societies and medical professionals. An initiation of a national strategy on cardiovascular prevention is proposed based on lifestyle modification (healthy diet, physical activity and smoking cessation) through actions in different settings. At the population level, regulation of food advertising, elimination of trans fats and reduction of added sugar are feasible and cost-effective interventions to help control dyslipidemias and reduce CVR. In the health setting, it is proposed to facilitate the application of guidelines, improve training for medical professionals, and include CVR assessment among the quality indicators. Scientific societies should collaborate with the health authorities and contribute to the generation and transmission of knowledge. Finally, it is in the hands of professionals to apply the concept of CVR, promote healthy lifestyles, and make efficient use of available pharmacological treatments.

Background African Americans (AA) have lower triglycerides (TG) and higher high density lipoprotein-cholesterol (HDL-C) than other ethnic groups yet they also have higher risk for developing diabetes mellitus despite the strong relationship of dyslipidemia with insulin resistance. No studies directly compare adolescents and adults with regard to relationships amongst dyslipidemia, C-reactive protein (hsCRP), and insulin resistance. Here we compare AA adolescents to adults with regard to the relationships of adiposity-related lipid risk markers (TG/HDL ratio and non HDL-C) with body mass index (BMI), waist circumference (WC), homeostasis model of insulin resistance (HOMA), and hsCRP. Methods Two cohorts of healthy AA were recruited from the same urban community. Participants in each cohort were stratified by TG/HDL ratio (based on adult tertiles) and non-HDL-C levels. BMI, WC, HOMA and hsCRP were compared in adolescents and adults in the low, middle and high lipid strata. Results Prevalence of TG/HDL ratio greater than 2.028 (high group) was 16% (44/283) in adolescents and 33% (161/484) in adults; prevalence of non HDL-C above 145 and 160 respectively was 8% (22/283) in adolescents and 12% (60/484) in adults. HsCRP values were lower and HOMA values were higher in adolescents (both p < 0.01). As both TG/HDL ratio and non HDL-C strata increased, BMI, WC, HOMA, and hsCRP increased in both adolescents and adults. In the high TG/HDL and non HDL-C groups, BMI and WC were similar in adolescents vs. adults (BMI 34 kg/m2 vs 32 kg/m2; WC 101 cm vs 101 cm). After adjusting for non-HDL-C and other covariates, a 2-fold increase in TG/HDL was associated with increases of 10.4% in hsCRP (95% CI: 1.1% – 20.5%) and 24.2% in HOMA (95% CI: 16.4% – 32.6%). Non-HDL-C was not significant in models having TG/HDL. Conclusions Elevated TG/HDL ratio is associated with similar inflammation and metabolic risk relationships in adolescent and adult African-Americans. PMID:26073396

We report the development of a new combinatorial approach that allows for peptide-mediated selective tissue targeting of nuclear hormone pharmacology while eliminating adverse effects in other tissues. Specifically, we report the development of a glucagon-like peptide-1 (GLP-1)-estrogen conjugate that has superior sex-independent efficacy over either of the individual hormones alone to correct obesity, hyperglycemia and dyslipidemia in mice. The therapeutic benefits are driven by pleiotropic dual hormone action to improve energy, glucose and lipid metabolism, as shown by loss-of-function models and genetic action profiling. Notably, the peptide-based targeting strategy also prevents hallmark side effects of estrogen in male and female mice, such as reproductive endocrine toxicity and oncogenicity. Collectively, selective activation of estrogen receptors in GLP-1–targeted tissues produces unprecedented efficacy to enhance the metabolic benefits of GLP-1 agonism. This example of targeting the metabolic syndrome represents the discovery of a new class of therapeutics that enables synergistic co-agonism through peptide-based selective delivery of small molecules. Although our observations with the GLP-1–estrogen conjugate justify translational studies for diabetes and obesity, the multitude of other possible combinations of peptides and small molecules may offer equal promise for other diseases.

Guidelines from the National Cholesterol Education Program (NCEP), ACC/AHA, and NLA; recent clinical trials involving non-statin therapies. Not applicable. At the authors' discretion, preference was given to references focusing on guidelines and recent clinical trials involving dyslipidemia management. In late 2013, the ACC/AHA released guidelines on the treatment of blood cholesterol to reduce risk for atherosclerotic cardiovascular disease (ASCVD) in adults. Reflecting contemporary evidence-based literature, low-density lipoprotein cholesterol (LDL-C) and non-high-density lipoprotein cholesterol (non-HDL-C) numeric treatment goals were eliminated, and a new method of risk assessment (the Pooled Cohort Equations) was recommended. The guidelines emphasized lipid lowering in 4 patient populations proven to benefit from statin therapy, recommending moderate to high-intensity statin dosing, with no additional drug therapies and limited ongoing monitoring. Clinical controversies ignited by these guidelines led to the publication of recommendations by the NLA in 2014 and 2015. Part 1 of the NLA recommendations incorporated parts of both the ATP III guidelines and the 2013 ACC/AHA guidelines along with updated original recommendations. These recommendations provided numeric LDL-C, non-HDL-C, and apolipoprotein B treatment goals and potential additional ASCVD risk factors, with stepwise risk assessment based on traditional cardiac risk factors and multiple assessment tools. In addition to statins, the 2014 NLA recommendations highlighted the benefit of additional or alternative lipid-lowering therapies. Part 2 of the NLA recommendations expanded the guidance for treatment of special populations and prioritized ezetimibe as a

To evaluate the prevalence of hyperglycemia and dyslipidemia in the population of Isabela, Galápagos, Ecuador, across gender and age (above or below 50). In this population-based retrospective cross-sectional study among individuals in Isabela, Galápagos, Ecuador, demographic and metabolic factors were evaluated based on World Health Organization (WHO) Global Guidelines. The population overall exceeded the WHO guidelines for cardiovascular health. As to be expected, there was significance in the trend of increasing dyslipidemia and hyperglycemia with age except postprandial glucose. In those individuals below the age of 50, 8.0%, 49% and 26% had hyperglycemia, hypercholesterolemia and hypertriglyceridemia, respectively. However, in those above 50, they measured 24%, 68% and 36% respectively, showing a significant increase. Hyperglycemia and dyslipidemia appear to be prevalent in Isabela, Galápagos, Ecuador and this pilot study supports further research into metabolic syndrome and diabetes. Such data may help in healthcare planning and screening to ensure not only timely diagnosis, but prevention. The limitations of this data illustrate modalities that data collection can be improved, such as having a linked clinical history to the data itself and better patient follow up for such entities as post prandial glucose, for example. However, this pilot study presents a starting point for future directions of research, such as ascertaining prevalence of diabetes type II, metabolic syndrome and cardiovascular disease.

Since the last publication of the recommendations for the management and treatment of dyslipidemia, new clinical trial data have emerged that support a more vigorous approach to lipid lowering in specific patient groups. The decision was made to update the lipid guidelines in collaboration with the Canadian Cardiovascular Society. A systematic electronic search of medical literature for original research consisting of blinded, randomized controlled trials was performed. Meta-analyses of studies of the efficacy and safety of lipid-lowering therapies, and of the predictive value of established and emerging risk factors were also reviewed. All recommendations are evidence-based, and have been reviewed in detail by primary and secondary review panels. Major changes include a lower low-density lipoprotein cholesterol (LDL-C) treatment target (lower than 2.0 mmol/L) for high-risk patients, a slightly higher intervention point for the initiation of drug therapy in most low-risk individuals (LDL-C of 5.0 mmol/L or a total cholesterol to high-density lipoprotein cholesterol ratio of 6.0) and recommendations regarding additional investigations of potential use in the further evaluation of coronary artery disease risk in subjects in the moderate-risk category.

To study the relationship between resting heart rate and blood lipid level. A total of 9 415 subjects aged ⋝ 40 years were included in the present study. Their resting heart rate was monitored and their serum levels of triglyceride (TG), total cholesterol (TC), low density lipoprotein cholesterol (LDL-C) and high density lipoprotein cholesterol (HDL-C) were measured to define dyslipidemia according to the 2007 Chinese Guidelines on Prevention and Treatment of Dyslipidemia in Adults. The subjects were divided into group A with their resting heart rate <70 beats/min, group B with their resting heart rate =70-79 beats/min, group C with their resting heart rate =80-89 beats/min, and group D with their resting heart rate ⋝ 90 beats/min. High TG, TC, and LDL-C were presented across the resting heart rate (Ptrend <0.01). Multiple logistic regression analysis revealed that the risk of high TG and TC was higher in subjects with their resting heart rate ⋝ 90 beats/min than in those with their resting heart rate <70 beats/min (OR=1.42; 95% CI: 1.16-1.74 and OR=1.33; 95% CI: 1.09-1.64, respectively).

Similar trends were existed in the prevalence of hypercholesteremia, hypertriglyceridemia, high LDL-c and low HDL-c (all P<0.05). Among the Uighur groups, IFG group had higher dyslipidemia rate than that of euglycemia group (74%). However, there was no such difference in the Han groups. Logistic regression analysis revealed that risk factors associated with LDL-c were age, total cholesterol and 2 h postprandial blood glucose for the Uighur IFG patients. However, gender and total cholesterol were risk factors for Han IFG patients. Uighur IFG patients had higher incidence of dyslipidemia than that of Han IFG patients. For Uyghur IFG patients, closing follow-up of total cholesterol and 2 h postprandial blood glucose were necessary. As to the Han IFG patients, we should pay more attention to male and total cholesterol in order to lower LDL-c levels. So, appropriately preventive and therapeutic measures should be chosen based on the characteristics of abnormal lipid profiles in different nationality.

Dyslipidemia is a risk factor for the progression of chronic kidney disease (CKD). While conventional lipid lowering therapy provides a benefit to CKD management, the effect of statins on eGFR remains unclear. A prospective, multi-center, open-labeled, randomized trial. Total of 349 CKD patients with hyperlipidemia were randomized into 2 groups, and followed for 2 years. Group A included patients who were treated with atorvastatin. Group C were treated with conventional lipid lowering drugs other than statin. Primary endpoint was changes in eGFR. Secondary endpoints included changes in urinary albumin excretion, serum LDL-C, serum triglyceride, cardio-vascular events and all-cause mortality. As the primary endpoint, eGFR decreased by 2.3 ml/min/1.73 m 2 in Group A and by 2.6 ml/min/1.73 m 2 in Group C, indicating that there was no difference in change of eGFR between the two groups. As secondary endpoints, atorvastatin succeeded to reduce serum LDL-C level significantly and rapidly, but conventional therapy did not. In fact, mean LDL-C level did not reach the target level of 100 mg/dl in Group C. Serum triglyceride was lowered only by atorvastatin, but not conventional drugs. The number of cardiovascular events and all-cause mortality did not differ between in two groups. The ASUCA (Assessment of Clinical Usefulness in CKD Patients with Atorvastatin) trial demonstrated that atorvastatin failed to exhibit reno-protections compared to conventional therapy in Japanese patients with dyslipidemia and CKD. It would be due in part to the ability of atorvastatin to more potently reduce serum LDL and triglycerides compared to conventional therapy.

Patients with dyslipidemia are often treated with statins to reduce lipids and hence cardiovascular risk, but treatment response is variable, partly due to genetic factors. We studied the influence of 6 gene variants (APOE c.526C > T (APOE2), APOE c.388T > C (APOE4), SLCO1B1 c.521T > C, CYP3A4 c.-392G > A, HMGCR c.1564-106A > G, and LPA c.3947 + 467T > C) on statin efficacy assessing 2 indicators: the percent reduction in total cholesterol (TC) and non-HDL cholesterol (non-HDL), as well as the achievement of therapeutic goals. The study was performed in a group of patients (n = 100) without previous pharmacological treatment. Multiple regression models were used to calculate the percentage of explanation in response variability added by every variant to a basal model constructed with significant nongenetic control variables. The most influential variant was HMGCR c.1564-106A > G (rs3846662), and carriers showed a significantly lower reduction in TC and non-HDL. This variant is related to an alternative splicing involving exon 13, which is also regulated by lipid concentrations in patients without the variant. Concerning therapeutic goals, HMGCR c.1564-106A > G hindered the achievement of TC targets on patients. The HMGCR c.1564-106A > G variant was associated with less statin efficacy to decrease cholesterol. © 2018 Wiley Periodicals, Inc.

The aim of the present study was to examine the association between peripheral differential leukocyte counts and dyslipidemia in a Chinese hypertensive population. A total of 10,866 patients with hypertension were enrolled for a comprehensive assessment of cardiovascular risk factors using data from the China Stroke Primary Prevention Trial. Plasma lipid levels and total leukocyte, neutrophil, and lymphocyte counts were determined according to standard methods. Peripheral differential leukocyte counts were consistently and positively associated with serum total cholesterol (TC), LDL cholesterol (LDL-C), and TG levels (all P < 0.001 for trend), while inversely associated with HDL cholesterol levels (P < 0.05 for trend). In subsequent analyses where serum lipids were dichotomized (dyslipidemia/normolipidemia), we found that patients in the highest quartile of total leukocyte count (≥7.6 × 10 9 cells/l) had 1.64 times the risk of high TG [95% confidence interval (CI): 1.46, 1.85], 1.34 times the risk of high TC (95% CI: 1.20, 1.50), and 1.24 times the risk of high LDL-C (95% CI: 1.12, 1.39) compared with their counterparts in the lowest quartile of total leukocyte count. Similar patterns were also observed with neutrophils and lymphocytes. In summary, these findings indicate that elevated differential leukocyte counts are directly associated with serum lipid levels and increased odds of dyslipidemia.

Treatment with statin may be beneficial for patients with chronic kidney disease (CKD). However, the debate over the clinical importance of statin in patients with predialysis advanced CKD remains unresolved. The objective of the article was to evaluate the effect of statin on mortality, cerebrovascular, and renal outcomes in patients with predialysis advanced CKD and dyslipidemia. Data on predialysis advanced CKD patients were retrieved from the National Health Insurance Research Database based on the guidelines for prescribing regular erythropoietin-stimulating agent in CKD patients. Patients with dyslipidemia were further selected and divided into 2 groups by their statin use after the prescribed erythropoietin-stimulating agent. All-cause mortality and cerebrovascular and renal outcomes were analyzed after propensity score matching. There were 2016 and 14,412 patients in the statin and nonstatin groups. Their average follow-up periods were 3.7 and 3.0 years, respectively. After 1:2 propensity score matching, the annual all-cause mortality rate was higher in the nonstatin than in the statin group (143.99 vs 109.50 per 1000 person-years; P < .001; hazard ratio: 0.73; 95% confidence interval: 0.68-080). The annual risk of ischemic stroke (P = .186) and intracranial hemorrhage (P = .322) were not significantly different between the 2 groups. The nonstatin group had a higher risk of dialysis than the statin group (1269.45 vs 1095.00 per 1000 person-years; P = .002). Adverse events were not significant between the 2 groups. Statins may reduce the all-cause mortality and reduced the risk of dialysis in patients with predialysis advanced CKD and dyslipidemia. However, statins have no impact on ischemic-hemorrhage stroke.

Individuals with dyslipidemia often develop type 2 diabetes, and diabetic patients often have dyslipidemia. It remains to be determined whether there are genetic connections between the 2 disorders. A female F2 cohort, generated from BALB/cJ (BALB) and SM/J (SM) Apoe-deficient (Apoe(-/-)) strains, was started on a Western diet at 6 weeks of age and maintained on the diet for 12 weeks. Fasting plasma glucose and lipid levels were measured before and after 12 weeks of Western diet. 144 genetic markers across the entire genome were used for quantitative trait locus (QTL) analysis. One significant QTL on chromosome 9, named Bglu17 [26.4 cM, logarithm of odds ratio (LOD): 5.4], and 3 suggestive QTLs were identified for fasting glucose levels. The suggestive QTL near the proximal end of chromosome 9 (2.4 cM, LOD: 3.12) was replicated at both time points and named Bglu16. Bglu17 coincided with a significant QTL for HDL (high-density lipoprotein) and a suggestive QTL for non-HDL cholesterol levels. Plasma glucose levels were inversely correlated with HDL but positively correlated with non-HDL cholesterol levels in F2 mice on either chow or Western diet. A significant correlation between fasting glucose and triglyceride levels was also observed on the Western diet. Haplotype analysis revealed that "lipid genes" Sik3, Apoa1, and Apoc3 were probable candidates for Bglu17. We have identified multiple QTLs for fasting glucose and lipid levels. The colocalization of QTLs for both phenotypes and the sharing of potential candidate genes demonstrate genetic connections between dyslipidemia and type 2 diabetes.

Obesity-related insulin resistance is associated with fatty liver, dyslipidemia, and low plasma adiponectin. Insulin resistance due to insulin receptor (INSR) dysfunction is associated with none of these, but when due to dysfunction of the downstream kinase AKT2 phenocopies obesity-related insulin resistance. We report 5 patients with SHORT syndrome and C-terminal mutations in PIK3R1, encoding the p85α/p55α/p50α subunits of PI3K, which act between INSR and AKT in insulin signaling. Four of 5 patients had extreme insulin resistance without dyslipidemia or hepatic steatosis. In 3 of these 4, plasma adiponectin was preserved, as in insulin receptor dysfunction. The fourth patient and her healthy mother had low plasma adiponectin associated with a potentially novel mutation, p.Asp231Ala, in adiponectin itself. Cells studied from one patient with the p.Tyr657X PIK3R1 mutation expressed abundant truncated PIK3R1 products and showed severely reduced insulin-stimulated association of mutant but not WT p85α with IRS1, but normal downstream signaling. In 3T3-L1 preadipocytes, mutant p85α overexpression attenuated insulin-induced AKT phosphorylation and adipocyte differentiation. Thus, PIK3R1 C-terminal mutations impair insulin signaling only in some cellular contexts and produce a subphenotype of insulin resistance resembling INSR dysfunction but unlike AKT2 dysfunction, implicating PI3K in the pathogenesis of key components of the metabolic syndrome.

The risk of death due to heart disease and stroke is up to four times higher in individuals with diabetes compared to individuals without diabetes. Most guidelines that address treatment of dyslipidemia in patients with diabetes consider diabetes a cardiovascular disease (CVD) “risk equivalent” and recommend intensive treatment of dyslipidemia for the purpose of CVD prevention. Statins (3-hydroxy 3-methylglutaryl coenzyme A reductase [HMG-CoA reductase] inhibitors) are first-line agents in achieving lipid goals as an adjunct to diet and exercise and should be used in most patients. In addition to lipid management and blood pressure control, glycemic control is a basic component in the management of diabetes. Glycemic control is achieved by combining diabetes self-management education, diet and exercise, and, where required, antihyperglycemic agents (OHAs). Persistence and adherence to therapy are critical in achieving recommended treatment goals. However, overall compliance with concomitantly prescribed OHAs and statins is low in patients with type 2 diabetes. Fixed-dose combination (FDC) therapies have been shown to improve adherence by reducing pill burden, the complexity of treatment regimen, and, potentially, cost. Based on the available evidence regarding the pharmacokinetics and the efficacy and safety profiles of each component drug, the sitagliptin/simvastatin FDC may provide a rational and well-tolerated approach to achieving better adherence to multiple-drug therapy and improved lipid lowering and glycemic control, with consequent reduction in cardiovascular risk, diabetic microvascular disease, and mortality in diabetic patients for whom treatment with both compounds is appropriate.

Dyslipidemia is a risk factor for the pathogenesis of Alzheimer's disease. Although, atorvastatin is a well-accepted lipid-lowering agent, the benefits of atorvastatin treatment through an anti-inflammatory mechanism are still unclear. The present study was designed to examine changes in inflammatory markers following administration of atorvastatin in dyslipidemic patients with a parental history of Alzheimer's disease. Dyslipidemic adults with a parental history of Alzheimer's disease were administered either 40 mg of atorvastatin or placebo for 18 months. Before and after the study, lpid levels, blood pressure, body weight and body mass index, and the inflammatory markers hs-Creactive protein, serum monocyte chemoattractant protien-1, interleukin-1β, interleukin-6, and tumor necrosis factor-α were tested. Baseline levels of lipids, body mass index, hs-Creactive protein, monocyte chemoattractant protien-1, interleukin- 1β, interleukin-6 and tumor necrosis factor-α did not show any difference between the two groups. However, after 18 months of atorvastatin treatment, all inflammatory markers significantly decreased in association with a reduction of lipid profiles, body mass index, bodyweight, and blood pressure, compared with those patients treated with placebo. Administration of atorvastatin corrected dyslipidemia in association with a reduction in inflammatory markers. Our results suggest that the therapeutic benefits of atorvastatin possibly involve an anti-inflammatory pathway.

Aims To investigate associations between novel human cytochrome P450 (CYP450) combinatory (multigene) and substrate-specific drug metabolism indices, and elements of metabolic syndrome, such as low density lipoprotein cholesterol (LDLc), high density lipoprotein cholesterol (HDLc), triglycerides and BMI, using physiogenomic analysis. Methods CYP2C9, CYP2C19 and CYP2D6 genotypes and clinical data were obtained for 150 consecutive, consenting hospital admissions with a diagnosis of major depressive disorder and who were treated with psychotropic medications. Data analysis compared clinical measures of LDLc, HDLc, triglyceride and BMI with novel combinatory and substrate-specific CYP450 drug metabolism indices. Results We found that a greater metabolic reserve index score is related to lower LDLc and higher HDLc, and that a greater metabolic alteration index score corresponds with higher LDLc and lower HLDc values. We also discovered that the sertraline drug-specific indices correlated with cholesterol and triglyceride values. Conclusions Overall, we demonstrated how a multigene approach to CYP450 genotype analysis yields more accurate and significant results than single-gene analyses. Ranking the individual with respect to the population represents a potential tool for assessing risk of dyslipidemia in major depressive disorder patients who are being treated with psychotropics. In addition, the drug-specific indices appear useful for modeling a variable of potential relevance to an individual’s risk of drug-related dyslipidemia. PMID:21861666

The lamin A/C (LMNA) gene encodes lamins A and C, which have an important role in nuclear cohesion and chromatin organization. Mutations in this gene usually lead to the so-called laminopathies, the primary cardiac manifestations of which are dilated cardiomyopathy and intracardiac conduction defects. Some mutations, associated with lipodystrophy but not cardiomyopathy, have been linked to metabolic abnormalities such as diabetes and severe dyslipidemia. Herein we describe a new phenotype associated with a mutation in exon 11 of the LMNA gene: hypertrophic cardiomyopathy, atrioventricular block, severe dyslipidemia and diabetes. A 64-year-old woman with hypertrophic cardiomyopathy and a point mutation in exon 11 of the LMNA gene (c.1718C>T, Ser573Leu) presented with severe symptomatic ventricular hypertrophy and left ventricular outflow tract obstruction. She underwent septal alcohol ablation, followed by Morrow myectomy. The patient was also diagnosed with severe dyslipidemia, diabetes and obesity, and fulfilled diagnostic criteria for metabolic syndrome. No other characteristics of LMNA mutation-related phenotypes were identified. The development of type III atrioventricular block with no apparent cause, and mildly depressed systolic function, prompted referral for cardiac resynchronization therapy. In conclusion, the association between LMNA mutations and different phenotypes is complex and not fully understood, and can present with a broad spectrum of severity.

Yang, Chunyan; Li, Qianrong; Li, Yong

2014-01-01

Nuclear receptors (NRs) are important pharmaceutical targets because they are key regulators of many metabolic and inflammatory diseases, including diabetes, dyslipidemia, cirrhosis, and fibrosis. As ligands play a pivotal role in modulating nuclear receptor activity, the discovery of novel ligands for nuclear receptors represents an interesting and promising therapeutic approach. The search for novel NR agonists and antagonists with enhanced selectivities prompted the exploration of the extraordinary chemical diversity associated with natural products. Recent studies involving nuclear receptors have disclosed a number of natural products as nuclear receptor ligands, serving to re-emphasize the translational possibilities of natural products in drug discovery. In this review, the natural ligands of nuclear receptors will be described with an emphasis on their mechanisms of action and their therapeutic potentials, as well as on strategies to determine potential marine natural products as nuclear receptor modulators.

Statins are extensively used to treat dyslipidemia, but, because of their low tolerability profile, they are discontinued in a significant proportion of patients. Ezetimibe and nutraceuticals have been introduced as alternative therapies and have proved to be effective and well tolerated. A single-blind, single-center, randomized, prospective, and parallel group trial comparing a combination of nutraceuticals (red yeast rice, policosanol, berberine, folic acid, coenzyme Q10 and astaxanthin), called Armolipid Plus, and ezetimibe for 3 months in terms of efficacy and tolerability. Patients who did not achieve their therapeutic target (low-density lipoprotein cholesterol <100 mg/dl) could add the alternative treatment on top of randomized treatment for another 12 months: 100 patients who are dyslipidemic with ischemic heart disease treated with percutaneous coronary intervention were enrolled (ezetimibe n = 50, nutraceutical n = 50). Efficacy (lipid profile) and tolerability (adverse events, transaminases, and creatine kinase) were assessed after 3 and 12 months. After 3 months, 14 patients in the nutraceutical group achieved their therapeutic target, whereas none of the patients in the ezetimibe group did. At 1-year follow-up, 58 patients (72.5%) of the combined therapy group (n = 86) and 14 (100%) of the nutraceutical group reached the therapeutic goal. No patients experienced important undesirable effects. In conclusion, nutraceuticals alone or in combination with ezetimibe are well tolerated and improve the lipid profile in statin-intolerant patients with coronary heart disease. Further studies are needed to assess long-term effects of nutraceuticals on mortality. Copyright © 2015 Elsevier Inc. All rights reserved.

Both the metabolic syndrome (MS) and type 2 diabetes mellitus (T2DM) confer an increased risk of coronary heart disease and cardiovascular disease (CVD). As MS and T2DM become more prevalent, there will be an associated rise in the number of individuals with or at risk for CVD and its related disorders. One major underlying cause of CVD in patients with MS or T2DM is a characteristic form of atherogenic dyslipidemia. This article reviews the evidence that demonstrates that individuals with MS or T2DM are at increased risk for CVD and highlights atherogenic dyslipidemia as an important risk factor for the development of CVD in these individuals. In an accompanying article, current pharmacotherapies available for the management of atherogenic dyslipidemia in individuals with MS or T2DM are discussed. PMID:19614799

Aim of this review is to focus the attention on people living with HIV infection at risk of developing a cardiovascular event. What is or what would be the most suitable antiretroviral therapy? Which statin or fibrate to reduce the risk? How to influence behavior and lifestyles? Prevention of cardiovascular disease (CVD) risk remains the first and essential step in a medical intervention on these patients. The lifestyle modification, including smoking cessation, increased physical activity, weight reduction, and the education on healthy dietary practices are the main instruments. Statins are the cornerstone for the treatment of hypercholesterolemia. They have been shown to slow the progression or promote regression of coronary plaque, and could also exert an anti-inflammatory and immunomodulatory effect. However the current guidelines for the use of these drugs in general population are dissimilar, with important differences between American and European ones. The debate between American and European guidelines is still open and, also considering the independent risk factor represented by HIV, specific guidelines are warranted. Ezetimibe reduces the intestinal absorption of cholesterol. It is effective alone or in combination with rosuvastatin. It does not modify plasmatic concentrations of antiretrovirals. A number of experimental new classes of drugs for the treatment of hypercholesterolemia are being studied. Fibrates represent the first choice for treatment of hypertriglyceridemia, however, the renal toxicity of fibrates and statins should be considered. Omega 3 fatty acids have a good safety profile, but their efficacy is limited. Another concern is the high dose needed. Other drugs are acipimox and tesamorelin. Current antiretroviral therapies are less toxic and more effective than regimens used in the early years. Lipodistrophy and dyslipidemia are the main causes of long-term toxicities. Not all antiretrovirals have similar toxicities. Protease Inhibitors

Dyslipidemia occurs in approximately 70% of all liver transplant (LT) recipients, and no prior control studies have demonstrated any dietary intervention to change it. To analyze the effects of a dietary intervention on the lipid profile of dyslipidemic LT recipients. All LT recipients with dyslipidemia on clinical follow-up were enrolled. Anthropometric evaluation, food history, body composition (bioimpedance) and assessment of basal metabolism through indirect calorimetry were performed. Patients met with a dietitian and an individualized diet based on estimate of basal metabolism and consisting of 25% of the total energy value in total fat and <200 mg/day of cholesterol was prescribed. Total cholesterol (TC), HDL-cholesterol (HDL), LDL-cholesterol (LDL), triglycerides (TG) and anthropometric measures were measured at baseline and six months after intervention. Fifty-thee out of 56 patients concluded follow-up; age was 59±10 years; 29 were men (51.8%). The analysis pre- and post-intervention were, respectively: TC 238.9±30 and 165.1±35, p<0.001; LDL 154±33 and 90±29, p<0.001; and TG 168 (IQR=51-200) and 137 (IQR=94-177), p=<0.001. They were all modified at six months following intervention. At baseline, none of the patients had normal TC, and only 12 (22.7%) had optimal/near optimal LDL. Following dietary intervention, 45 patients (84.9%) reached normal TC and 50 (94.4%) had optimal/near optimal LDL. HDL and anthropometric measures were not modified. Dietary counseling with prescription of individualized diet based on estimate of basal metabolism through indirect calorimetry was able to manage dyslipidemia in most LT recipients; so, all dyslipidemic LT recipients must be enrolled on a dietary program.

Previous studies demonstrated independent contributions of plasma free amino acids (PFAAs) and high uric acid (UA) concentrations to increased risks of lifestyle-related diseases (LSRDs), but the important associations between these factors and LSRDs remain unknown. We quantified PFAAs and UA amongst Japanese subjects without LSRDs (no-LSRD, n = 2805), and with diabetes mellitus (DM, n = 415), dyslipidemia (n = 3207), hypertension (n = 2736) and metabolic syndrome (MetS, n = 717). The concentrations of most amino acids differed significantly between the subjects with and without hyperuricemia (HU) and also between the no-LSRD and LSRD groups (p < 0.05 to 0.001). After adjustment, the logistic regression analyses revealed that lysine in DM, alanine, proline and tyrosine in dyslipidemia, histidine, lysine and ornithine in hypertension, and lysine and tyrosine in MetS demonstrated significant positive associations with HU among the patients with LSRDs only (p < 0.05 to 0.005). By contrast, arginine, asparagine and threonine showed significant inverse associations with HU in the no-LSRD group only (p < 0.05 to 0.01). For the first time, we provide evidence for distinct patterns of association between PFAAs and HU in LSRDs, and postulate the possibility of interplay between PFAAs and UA in their pathophysiology.

Conflict of interest: none declared. Objective We aimed to evaluate the effects of Hibiscus sabdariffa (HS) calices on controlling dyslipidemia in obese adolescents. Methodology In this triple blind randomized placebo-controlled clinical trial which was registered in the Iranian registry for clinical trials (IRCT201109122306N2), 90 obese adolescents aged 12-18 years with documented dyslipidemia were randomly assigned in two groups of cases who received 2 grams of fine powdered calices of Hibiscus sabdariffa per day for one month and controls who received placebo powder with the same dietary and physical activity recommendations and duration of exposure. Full lipid profile and fasting blood sugar measured before and after the trial. Data were analyzed using multivariate general linear model. Findings Overall, 72 participants (mean age of 14.21±1.6, 35 boys) completed the trial. The two arms of the study (cases and controls) were not statistically different in terms of age, gender, weight, body mass index (BMI) and lipid profile before the trial. Serum total cholesterol, low density lipoprotein cholesterol and serum triglyceride showed a significant decrease in cases group but high density lipoprotein cholesterol level was not changed significantly. Conclusion It is concluded that Hibiscus sabdariffa calyces powder may have significant positive effects on lipid profile of adolescents which maybe attributed to its polyphenolic and antioxidant content. Further studies are needed on dose-response and formulation optimization. PMID:24082826

The effect of Hibiscus sabdariffa calyx extract was evaluated in high-fructose-induced metabolic syndrome rats. Insulin resistance, hyperglycemia, dyslipidemia and oxidative rout were induced in rats using high-fructose diet. High-fructose diet-fed rats were administered 100 and 200 mg kg(-1) body weight of H. sabdariffa extract for 3 weeks, starting from week 7 of high-fructose diet treatment. High-fructose diet significantly (P < 0.05) increased the serum levels of blood glucose, insulin, total cholesterol (TC), triacylglycerol (TAG), low-density lipoprotein cholesterol (LDLc) and very-low-density lipoprotein cholesterol (VLDLc), with a concomitant reduction in high-density lipoprotein cholesterol (HDLc). These alterations were significantly ameliorated by the extract. High-fructose diet-mediated decreases in the activities of superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GSH-Px), glutathione reductase (GSH-red) and glucose 6-phosphate dehydrogenase (Glc 6-PD) were significantly (P < 0.05) attenuated. Altered levels of reduced glutathione (GSH) and glutathione disulfide (GSSG) were significantly (P < 0.05) restored to normal. High-fructose diet-mediated increases in the concentrations of malondialdehyde, conjugated dienes, lipid hydroperoxides, protein carbonyl and percentage fragmented DNA were significantly (P < 0.05) lowered by the Hibiscus extract. Overall, aqueous extract of H. sabdariffa palliates insulin resistance, hyperglycemia, dyslipidemia and oxidative rout in high-fructose-induced metabolic syndrome rats. © 2015 Society of Chemical Industry.

Since Korean mistletoe (Viscum album) has been used for alleviating metabolic diseases, it may also prevent the impairment of energy, glucose, lipid, and bone metabolisms in an estrogen-deficient animal model. We determined that long-term consumption of Korean mistletoe water extract (KME) can alleviate menopausal symptoms such as hot flush, increased abdominal fat mass, dyslipidemia, hyperglycemia, and decreased bone mineral density in ovariectomized (OVX) rats fed a high-fat diet, and explored the mechanisms of the effects. OVX rats were divided into four groups and fed high-fat diets supplemented with either 0.6% dextrin (control), 0.2% lyophilized KME + 0.4% dextrin (KME-L), or 0.6% lyophilized KME (KME-H). Sham rats were fed with the high-fat diets with 0.6% dextrin as a normal-control without estrogen deficiency. After eight weeks, OVX rats exhibited impaired energy, glucose and lipid metabolism, and decreased uterine and bone masses. KME-L did not alleviate energy dysfunction. However, KME-H lowered serum levels of total-, LDL-cholesterol, and triglycerides and elevated serum HDL-cholesterol levels in OVX rats with dyslipidemia, to similar levels as normal-control rats. Furthermore, KME-H improved HOMA-IR, an indicator of insulin resistance, in OVX rats. Surprisingly, KME-H fed rats had greater lean mass in the abdomen and leg without differences in fat mass but neither dosage of KME altered bone mineral density in the lumbar spine and femur. The increased lean mass was related to greater phosphorylation of mTOR and eukaryotic translation initiation factor 4E-binding protein 1 (4E-BP1) in the quadriceps muscles. Hepatic triglyceride contents were lowered with KME-H in OVX rats by increasing carnitine palmitoyltransferase-1 (CPT-1) expression and decreasing fatty acid synthase (FAS) and sterol regulatory element-binding protein-1c (SREBP-1c) expression. In conclusion, KME may be useful for preventing some menopausal symptoms such as hot flushes, dyslipidemia

[CYP7A1 gene polymorphism and the characteristics of dyslipidemias in patients with nonalcoholic fatty liver disease concurrent with hypothyroidism].

To investigate the association of the polymorphic variants -204A > C (rs 3808607) in the CYP7A1 gene with the development of dyslipidemias in healthy individuals, in patients with non-alcoholic fatty liver disease (NAFLD) and in those with NAFLD concurrent with hypothyroidism. DNA samples and lipidograms were examined in 180 patients, including 60 healthy individuals (Group 1), 60 patients with hypothyroidism concurrent with NAFLD (Group 2), and 60 patients with NAFLD (Group 3). All the patients underwent ultrasound examination of the thyroid gland and abdominal cavity organs; FibroMax scores were calculated. All the study groups most frequently showed a homozygous AA genotype (86.6% of cases in Group 1, 80% in Group 2, and 83.3% in Group 3). The development of NAFLD in CC genotype carriers is characterized by the most pronounced changes in lipid metabolism (atherogenic index (AI), 7.32 in Group 3) compared to the genotypes AA (AI, 4.56 in Group 2 and 1.73 in Group 1) and CC (AI, 6.43 in Group 2 and 2.52 in Group 1) in functional insufficiency of thyroid hormones and relative normal conditions. The analysis of the relationship of polymorphic variants CYP7A1 rs 38088607 to lipid metabolic disturbances in the study groups showed that the significantly higher levels of atherogenic cholesterol fractions were determined in the CC genotype compared to AA genotype carriers and they did not depend on the presence of NAFLD and hypothyroidism. The findings make it possible to consider the AA homozygous genotype of variant mutation CYP7A1 rs 38088607 as protective against dyslipidemia. However, in functional insufficiency of thyroid hormones, the level of triglycerides is significantly higher in both genotypes, which suggests that hypothyroidism plays an essential role in the development of dyslipidemia and NAFLD.

We shall open our overview of issues related to obesity and hyperlipoproteinemia (HLP) or dyslipidemia with a notoriously known truth (that some are still reluctant to accept): HLP/DLP is not obesity. It is certainly not possible to put an equal sign between subcutaneous fat and the level of plasma lipids and lipoproteins. On the other hand, it is obvious that there is a number of connecting links between HLP/DLP and obesity. These associations on one side and differences on the other are the focus of this review paper. (1) HLP/DLP as well as obesity represent a group of high incidence metabolic diseases (gradually evolving from epidemic to pandemic) that affect several tens of percent of inhabitants. (2) Both HLP/DLP and obesity often occur concurrently, often as a result of unhealthy lifestyle. However, genetic factors are also been studies and it is possible that mutual predispositions for the development of both diseases will be identified. At present, it is only possible to conclude that obesity worsens lipid metabolism in genetically-determined HLP. (3) Both these metabolic diseases represent a risk factor for other pathologies, cardiovascular diseases are the most important common complication of both conditions (central type of obesity only). Concurrent presence of HDL/DLP and obesity is often linked to other diagnoses, such as type 2 diabetes mellitus (DM2T), hypertension, pro-coagulation or pro-inflammatory states; all as part of so called metabolic syndrome. (4) Patients with metabolic syndrome and, mainly, central obesity usually have typical dyslipidemia with reduced HDL-cholesterol (HDL-C) and sometimes hypertriglyceridaemia. Current treatment of HDL/DLP aims to first impact on the primary aim, i.e. LDL-cholesterol (LDL-C), and than influence HDL-C. (5) It seems that the therapeutic efforts in HLP/DLP and obesity will go in the same direction. I will skip the trivial (and difficult to accept by patients) dietary changes. Pharmacotherapy, however

Klinefelter's syndrome (KS) is a genetic syndrome that presents with hypogonadism and is associated with metabolic syndrome. Patients demonstrating hypogonadism show a greater prevalence of metabolic syndrome due to changes in body composition. We aimed to determine the association between KS and dyslipidemia. The KS group comprised 55 patients who visited the infertility clinic for an infertility evaluation and were confirmed as having a diagnosis of KS. The control group comprised 120 patients who visited the clinic for health screening. Patient characteristics were compared between the two groups with respect to height, weight, body mass index (BMI), testosterone, total cholesterol, high-density lipoprotein (HDL) cholesterol, low-density lipoprotein (LDL) cholesterol, and triglyceride (TG) levels. Height and weight were significantly greater in patients belonging to the KS group, but no statistically significant difference was found with respect to the BMI. Testosterone levels in patients belonging to the KS group were significantly lower compared to the control group (2.4 ± 2.6 vs. 5.2 ± 1.8 ng/mL, P < 0.001). Compared to the control group, TG levels in patients belonging to the KS group were increased (134.9 ± 127.8 vs. 187.9 ± 192.1 mg/dL, P = 0.004) and HDL cholesterol was significantly decreased (51.2 ± 22.0 vs. 44.0 ± 9.5 mg/dL, P = 0.009). LDL cholesterol and total cholesterol were not significantly different between the two groups (P = 0.076 and P = 0.256, respectively). Significant differences were noted between patients belonging to the KS group and normal control group with respect to elevated TG and decreased HDL cholesterol levels. © 2017 The Korean Academy of Medical Sciences.

Dyslipidemia and genetic polymorphisms are associated with increased risk for developing cardiovascular diseases, and watermelon appears to have the potential to improve hyperlipidemia due to the presence of nutrients such as arginine and citrulline. To test the hypolipidemic effect of watermelon extract (Citrullus lanatus) and the influence of the methylenetetrahydrofolate reductase genotype (MTHFR C677T) on supplementation response. This is an experimental clinical phase II randomized and double-blind study. Forty-three subjects with dyslipidemia were randomly divided into 2 groups: experimental (n = 22) and control (n = 21) groups. The subjects were supplemented daily for 42 days with 6 g of watermelon extract or a mixture of carbohydrates (sucrose/glucose/fructose). The use of watermelon extract reduced plasma total cholesterol (p < 0.05) and low-density lipoprotein (p < 0.01) without modifying triglycerides, high-density lipoprotein, and very low-density lipoprotein values. Only carriers of the T allele (MTHFR C677T) showed decreasing concentrations of low-density lipoprotein (p < 0.01). No changes in anthropometric parameters analyzed were observed. This is the first study to demonstrate the beneficial effect of the consumption of watermelon extract in reducing plasma levels of lipids in humans. The MTHFR C677T polymorphism did not affect the plasma lipid concentration but made individuals more responsive to treatment with watermelon. The consumption of this functional food represents an alternative therapy in the combined treatment of patients with dyslipidemia, promoting health and minimizing the development of risk factors for cardiovascular diseases.

To examine cardiovascular disease risk factors and risk clusters in Swedish persons with traumatic wheelchair-dependent paraplegia. Prospective examination. A total of 135 individuals aged 18-79 years with chronic (>or= 1 year) post-traumatic paraplegia. Cardiovascular disease risk factors; dyslipidemia, impaired fasting glucose, hypertension, overweight, smoking, and medication usage for dyslipidemia, hypertension, and diabetes mellitus, were analyzed according to authoritative guidelines. Stepwise regression tested the effects of age, gender, and injury characteristics on cardiovascular disease risks. High-prevalence risk factors were dyslipidemia (83.1%), hypertension (39.3%), and overweight (42.2%) with pervasive clustering of these risks. Being older was related to increased cardiovascular disease risk, except for dyslipidemia. Hypertension was more common in low-level paraplegia. Prevalence of impaired fasting glucose was lower than previously reported after paraplegia. A high percentage of persons being prescribed drug treatment for dyslipidemia and hypertension failed to reach authoritative targets for cardiovascular disease risk reduction. Swedish persons with paraplegia are at high risk for dyslipidemia, hypertension, and overweight. Impaired fasting glucose was not as common as reported in some previous studies. Pharmacotherapy for dyslipidemia and hypertension often failed to achieve recommended targets. Population-based screening and therapeutic countermeasures to these cardiovascular disease risks are indicated.

The relationship between muscle strength and cardiometabolic risk factors in youth, and the potential influence of vitamin D status on this relationship, is not well understood. This study examined associations between muscle strength and dyslipidemia, serum 25-hydroxyvitamin D [25(OH)D], and weight status in diverse schoolchildren. Measures of hand-grip strength (standardized for sex and body weight), anthropometrics (height and weight converted to BMI z-score [BMIz]), sociodemographics, and fasting blood concentrations of plasma HDL-C and triglycerides and serum 25(OH)D were collected from 350 4th-8th grade schoolchildren (11.2 ± 1.3 y, 49.4% female, 56.3% non-white/Caucasian). Logistic regression was used to measure associations between standardized tertiles of grip strength and blood lipids, 25(OH)D, and weight status along with associations between 25(OH)D and dyslipidemia and weight status. Children with higher grip strength had lower odds of overweight/obesity (OR: 0.03, 95% CI: 0.01-0.06, in the highest tertile of grip strength vs. lowest, p for trend< 0.0001), borderline/low HDL-C (OR: 0.28, 95% CI: 0.16-0.50, p for trend< 0.0001), and borderline/high triglycerides (OR: 0.48, 95% CI: 0.25-0.92, p for trend< 0.05), adjusting for covariates. Associations between blood lipids and grip strength became non-significant after further adjustment for BMIz. No association was observed between grip strength and 25(OH)D, nor between 25(OH)D and borderline/low HDL-C or weight status; however, vitamin D sufficiency was associated with lower odds of borderline/high triglycerides compared with vitamin D deficiency (OR: 0.26, 95% CI: 0.09-0.74, p for trend< 0.05) before BMIz adjustment. Among racially/ethnically diverse children, muscle strength was associated with lower dyslipidemia. Longitudinal studies are needed to explore whether changes in muscle strength impact this relationship in children, independent of weight status. This study was registered at www

The non-pharmacological approach to cholesterol control in patients with hyperlipidemia is based on the promotion of a healthy diet and physical activity. Thus, to help patients change their habits, it is essential to identify the most effective approach. Many efforts have been devoted to explain changes in or adherence to specific health behaviors. Such efforts have resulted in the development of theories that have been applied in prevention campaigns, and that include brief advice and counseling services. Within this context, Motivational Interviewing has proven to be effective in changing health behaviors in specific cases. However, more robust evidence is needed on the effectiveness of Motivational Interviewing in treating chronic pathologies -such as dyslipidemia- in patients assisted by general practitioners. This article describes a protocol to assess the effectiveness of MI as compared with general practice (brief advice), with the aim of improving lipid level control in patients with dyslipidemia assisted by a general practitioner. An open, two-arm parallel, multicentre, cluster, controlled, randomized, clinical trial will be performed. A total of 48-50 general practitioners from 35 public primary care centers in Spain will be randomized and will recruit 436 patients with dyslipidemia. They will perform an intervention based either on Motivational Interviewing or on the usual brief advice. After an initial assessment, follow-ups will be performed at 2, 4, 8 and 12 months. Primary outcomes are lipid levels (total cholesterol, HDL cholesterol, LDL cholesterol, triglycerides) and cardiovascular risk. The study will assess the degree of dietary and physical activity improvement, weight loss in overweight patients, and adherence to treatment guidelines.

Dyslipidemia in chronic kidney disease: are statins still indicated in reduction cardiovascular risk in patients on dialysis treatment?

Chronic kidney disease (CKD) is an increasingly health disease all around the world with a high burden of mortality and cardiovascular (CV) morbidity rate. Even when renal replacement therapy is reached, more than half patients die, mainly for CV causes due either to uremia-related cardiovascular risk factors (such as anemia, hyperhomocysteinemia, mineral bone disease-CKD with hyperparathyroidism, oxidative stress, hypoalbuminemia, chronic inflammation, prothrombotic factors) or to traditional ones (age, male gender, diabetes, obesity, hypertension, smoking, insulin levels, family history, dyslipidemia). Among the latter causes dyslipidemia represents one of the major, potentially correctable risk factor. Statins have demonstrated to effectively and safely reduce cholesterol levels in CKD patients. Here we will examine the effects of statins on CV risk factors in CKD patients and particularly in patients on dialysis treatment, in the light of the unfavorable results of the large trials 4D and AURORA, recently published, underlining the role of malnutrition/inflammation as confounding factor. Probably it will be that only with a real prevention, starting statins even in the early stages of CKD, as indicated by post hoc analysis of large trials, that we will reach results in reducing the mortality rate in CKD patients. In the meanwhile, all the other remediable CV risk factors have to be at the same time corrected. © 2010 Blackwell Publishing Ltd.

The Alcohol Use Disorders Identification Test (AUDIT) questionnaire is a simple and useful method for the early detection of hazardous and harmful drinking. In this study, we examined the association between alcohol drinking pattern and dyslipidemia in Korean adults. This cross-sectional study included 14,308 participants who took part in the 2010-2012 Korean National Health and Nutrition Examination Survey. We categorized alcohol drinking patterns into three groups. We classified dyslipidemia into hypercholesterolemia, hypertriglyceridemia, hypo-HDL-cholesterolemia, hyper-LDL-cholesterolemia, and hyper-non-HDL-cholesterolemia. Of those who participated, 25.1% of men and 4.8% of women were high-risk drinkers. Compared with the low-risk group, Odd Ratios for hypercholesterolemia and hypertriglyceridemia in the high-risk group were 1.198 (1.001-1.434) and 1.979 (1.622-2.413) for men. Odd Ratios for hypo-HDL-cholesterolemia in the high-risk group was 0.351 (0.279-0.441) in men and 0.413 (0.291-0.586) in women. Compared with the low-risk participants, the high-risk group was associated with higher prevalence and increased risk for hyper-LDL-cholesterolemia in both sexes (1.541 [1.467-1.913] for men and 1.631 [1.034-2.575] for women). High-risk drinking was associated with higher risk for hypertriglyceridemia and hyper-LDL-cholesterolemia in both sexes and hypercholesterolemia in men but lower risk for hypo-HDL-cholesterolemia in both sexes.

We aimed to examine the cross-sectional associations of plasma total homocysteine (tHcy) concentrations and methylenetetrahydrofolate reductase ( MTHFR) C677T genotype with dyslipidemia. A total of 231 patients with mild-to-moderate essential hypertension were enrolled from the Huoqiu and Yuexi communities in Anhui Province, China. Plasma tHcy levels were measured by high-performance liquid chromatography. Genotyping was performed by TaqMan allelic discrimination technique. Compared with MTHFR 677 CC + CT genotype carriers, TT genotype carriers had higher odds of hypercholesterolemia (adjusted odds ratio [OR] [95% confidence interval (CI)]: 2.7 [1.4-5.2]; P = .004) and higher odds of abnormal low-density lipoprotein cholesterol (adjusted OR [95% CI]: 2.3 [1.1-4.8]; P = .030). The individuals with the TT genotype had higher concentrations of log(tHcy) than those with the 677 CC + CT genotype (adjusted β [standard error]: .2 [0.03]; P < .001). Patients with tHcy ≥ 10 μmol/L had significantly higher odds of hypercholesterolemia (adjusted OR [95% CI]: 2.4 [1.2-4.7]; P = .010). Furthermore, patients with both the TT genotype and the tHcy ≥ 10 μmol/L had the highest odds of hypercholesterolemia (adjusted OR [95% CI]: 4.1 [1.8-9.4]; P = .001) and low-density lipoprotein cholesterol (adjusted OR [95% CI]: 2.4 [1.0-6.0]; P = .064). This study suggests that both tHcy and the MTHFR C677T gene polymorphism may be important determinants of the incidence of dyslipidemia in Chinese patients with essential hypertension. Further studies are needed to confirm the role of tHcy and the MTHFR C677T mutation in the development of dyslipidemia in a larger sample.

Nuclear receptor coactivator-3 (NCOA3) is involved in various physiological processes. Emerging evidence from previous studies using animal models suggests that the NCOA3 gene (NCOA3) plays a critical role in lipid metabolism as well as adipogenesis and obesity. The present study aims to investigate the association between NCOA3 SNPs and dyslipidemia in the Chinese Han population. Five hundred and twenty-nine (529) Chinese Han subjects were recruited. Four tag SNPs (rs2425955G > T, rs6066394T > C, rs10485463C > G, and rs6094753G > A) in NCOA3, selected from the HapMap website, were genotyped using MALDI-TOF mass spectrometry. Data analysis was performed using SPSS 16.0, SNPStats and haploview 4.2. Four SNPs (rs2425955, rs6066394, rs10485463, and rs6094753) were associated with triglyceride levels. Except for SNP rs10485463, genotype distributions and allele frequencies of the other three NCOA3 SNPs (rs2425955, rs6066394, and rs6094753) were significantly different between hypertriglyceridemia subjects and normal group. Significant differences were also observed in allele frequencies and genotype distributions of SNP rs10485463 between low-HDL cholesterolemia subjects and normal group. Carriers of rs2425955 T allele had a lower risk of hypertriglyceridemia compared to GG genotype. Similar results were observed from rs6094753. Subjects with rs6066394 CT genotype had a lower risk of hypertriglyceridemia than those with the TT genotype; however, CC and TT genotypes showed no significant difference in the risk of hypertriglyceridemia. Similar results were found in the association between rs6066394 and hypercholesterolemia. The variant alleles of rs2425955, rs6066394 and rs6094753 were associated with a lower risk of hypertriglyceridemia compared with the wild-type alleles. The G allele of rs10485463 was associated with an increased risk of low-HDL cholesterolemia. In the log-additive model the association between rs2425955 and hypertriglyceridemia remained significant

We studied the effect of dyslipidemia induced by poloxamer 407 (300 mg/kg twice a week for 30 days) on cellular composition of the spleen and splenocyte lysosomes in mice. Changes in blood lipid profile included elevated concentrations of total cholesterol, aterogenic LDL, and triglycerides most pronounced in 24 h after the last poloxamer 407 injection; gradual normalization of lipid profile was observed in 4 days (except triglycerides) and 10 days. The most pronounced changes in the spleen (increase in organ weight and number of cells, inhibition in apoptosis, and reduced accumulation of vital dye acridine orange in lysosomes) were detected on day 4; on day 10, the indices returned to normal. Cathepsin D activity in the spleen also increased at these terms. The relationship between changes in the cellular composition of the spleen and dynamics of serum lipid profile in mice in dyslipidemia caused by repeated administrations of relatively low doses of poloxamer 407 is discussed.

Background Coronary heart disease is increasing in urban Indian subjects and lipid abnormalities are important risk factors. To determine secular trends in prevalence of various lipid abnormalities we performed studies in an urban Indian population. Methods Successive epidemiological Jaipur Heart Watch (JHW) studies were performed in Western India in urban locations. The studies evaluated adults ≥ 20 years for multiple coronary risk factors using standardized methodology (JHW-1, 1993–94, n = 2212; JHW-2, 1999–2001, n = 1123; JHW-3, 2002–03, n = 458, and JHW-4 2004–2005, n = 1127). For the present analyses data of subjects 20–59 years (n = 4136, men 2341, women 1795) have been included. In successive studies, fasting measurements for cholesterol lipoproteins (total cholesterol, LDL cholesterol, HDL cholesterol) and triglycerides were performed in 193, 454, 179 and 252 men (n = 1078) and 83, 472, 195, 248 women (n = 998) respectively (total 2076). Age-group specific levels of various cholesterol lipoproteins, triglycerides and their ratios were determined. Prevalence of various dyslipidemias (total cholesterol ≥ 200 mg/dl, LDL cholesterol ≥ 130 mg/dl, non-HDL cholesterol ≥ 160 mg/dl, triglycerides ≥ 150 mg/dl, low HDL cholesterol <40 mg/dl, high cholesterol remnants ≥ 25 mg/dl, and high total:HDL cholesterol ratio ≥ 5.0, and ≥ 4.0 were also determined. Significance of secular trends in prevalence of dyslipidemias was determined using linear-curve estimation regression. Association of changing trends in prevalence of dyslipidemias with trends in educational status, obesity and truncal obesity (high waist:hip ratio) were determined using two-line regression analysis. Results Mean levels of various lipoproteins increased sharply from JHW-1 to JHW-2 and then gradually in JHW-3 and JHW-4. Age-adjusted mean values (mg/dl) in JHW-1, JHW-2, JHW-3 and JHW-4 studies respectively showed a significant increase in total cholesterol (174.9 ± 45, 196.0 �

Treatment targets in the management of dyslipidemias: which targets in whom?

The public health approach to prevention of atherosclerotic cardiovascular disease (ASCVD) continues to hold great potential for prevention. This approach includes diets low in saturated fats and cholesterol, maintaining desirable body weight, regular physical activity, and absence of cigarette smoking. But drug therapy is becoming more widely used. Statins have been available for treatment of elevated serum cholesterol for a quarter of a century. They have proven efficacious for reducing risk for atherosclerotic cardiovascular disease (ASCVD). They carry little toxicity, and now that some derivatives are generic, they are inexpensive. Statins have become standard of care for patients with established ASCVD. To achieve further reduction in ASCVD events through cholesterol lowering will require new combinations with older agents and development of new drugs. The future of secondary prevention lies in testing of old and new "add-on" agents. Indications for statin use in primary prevention is less clear-cut. But clinical-trial experience with statins point to enormous potential for reducing ASCVD in the population. At the same time, there are dangers of overuse and turning society into a "drug culture". To abandon the benefits of healthy lifestyles for excessive drug intervention would be unfortunate.

We previously identified rs6929846 of the butyrophilin, subfamily 2, member A1 gene (BTN2A1) as a susceptibility locus for myocardial infarction in Japanese individuals by a genome-wide association study. The aim of the present study was to examine the relation of the rs6929846 polymorphism of BTN2A1 to dyslipidemia in Japanese and Korean populations, given that dyslipidemia is an important risk factor for myocardial infarction. A total of 10,953 individuals from three independent subject panels were examined. The relations of the rs6929846 polymorphism of BTN2A1 to serum concentrations of triglycerides, high-density lipoprotein (HDL)-cholesterol and low-density lipoprotein (LDL)-cholesterol were examined in each subject panel. The C→T polymorphism (rs6929846) of BTN2A1 was significantly associated with serum concentrations of triglycerides in Japanese subject panels A (P=0.0004) and B (P=0.0010), and in the Korean population (P=0.0095), with the minor T allele being related to an increased serum concentration of triglycerides. The rs6929846 was associated with serum concentrations of HDL-cholesterol in Japanese subject panels A (P=0.0047) and B (P=0.0015), with the T allele being related to a decreased serum concentration of HDL-cholesterol, but not in the Korean population. This polymorphism was associated with the serum concentration of LDL-cholesterol only in Japanese subject panel B (P=0.0059), with the T allele being related to an increased serum concentration of LDL-cholesterol. The results suggest that BTN2A1 may be a susceptibility gene for hypertriglyceridemia in East Asian populations and for low serum HDL-cholesterol in the Japanese population. PMID:22977569

Background: Dyslipidemia is a disorder of lipoprotein metabolism, including lipoprotein overproduction or deficiency and it can be understood in the parlance of the closest conditions in Ayurveda, viz. Kapha Medo Margavarana (dyslipidemia), Atisthaulya (obesity) or Meda Roga and Prameha. Asanadi Ghanavati (AG) is a modified presentation of Asanadi Gana drugs referred in Ashtanga Hridaya and Gomutra Haritaki (GH) is described in Charaka Samhita under Shotha Chikitsa and Ashtanga Hridaya in Arsha Chikitsa. Aim: To evaluate and compare the clinical effect of AG and GH in Kapha Medo Margavarana. Materials and Methods: Patients with the high lipid profile were selected and randomly divided into two groups. In Group A (n = 30), patients were administered with tablet of AG 1 g (500 mg each) thrice a day for 8 weeks and in Group B (n = 30), tablet of GH in similar dose and duration. Effect of therapy was assessed by body circumference, Body Mass Index (BMI), cardinal symptoms like Anga-Gaurava, Bharavriddhi, etc., and lipid profile parameters. Result: AG decreased the serum cholesterol by 7.12%, Serum Triglyceride (S. TG) by 7.72%, Serum Low Density Lipoprotein (S. LDL) by 11.68%, Serum Very Low Density Lipoprotein (S. VLDL) by 7.73%, and had increased Serum High Density Lipoprotein (S. HDL) by 9.52%, with moderate improvement in 14.81% and mild improvement in 70.37% of patients. The GH decreased the serum cholesterol by 6.31%, S. TG by 9.61%, S. LDL by 12.55%, serum VLDL by 8.99%, and increased S. HDL by 10.52% with moderate improvement in 3.70%, and mild improvement in 74.07% patients. Conclusion: AG and GH are suggested to be used in Kleda Bahul Samprapti Janya Vyadhi and Ama Bahul Samprapti Janya Vyadhi respectively. PMID:25558160

New Drugs for Treating Dyslipidemia: Beyond Statins

PubMed Central

Ahn, Chang Ho

2015-01-01

Statins have been shown to be very effective and safe in numerous randomized clinical trials, and became the implacable first-line treatment against atherogenic dyslipidemia. However, even with optimal statin treatment, 60% to 80% of residual cardiovascular risk still exists. The patients with familial hypercholesterolemia which results in extremely high level of low density lipoprotein cholesterol (LDL-C) level and the patients who are intolerant or unresponsive to statins are the other hurdles of statin treatment. Recently, new classes of lipid-lowering drugs have been developed and some of them are available for the clinical practice. The pro-protein convertase subtilisin/kexintype 9 (PCSK9) inhibitor increases the expression of low density lipoprotein (LDL) receptor in hepatocytes by enhancing LDL receptor recycling. The microsomal triglyceride transport protein (MTP) inhibitor and antisense oligonucleotide against apolipoprotein B (ApoB) reduce the ApoB containing lipoprotein by blocking the hepatic very low density lipoprotein synthesis pathway. The apolipoprotein A1 (ApoA1) mimetics pursuing the beneficial effect of high density lipoprotein cholesterol and can reverse the course of atherosclerosis. ApoA1 mimetics had many controversial clinical data and need more validation in humans. The PCSK9 inhibitor recently showed promising results of significant LDL-C lowering in familial hypercholesterolemia (FH) patients from the long-term phase III trials. The MTP inhibitor and antisesnse oligonucleotide against ApoB were approved for the treatment of homozygous FH but still needs more consolidated evidences about hepatic safety such as hepatosteatosis. We would discuss the benefits and concerns of these new lipid-lowering drugs anticipating additional benefits beyond statin treatment. PMID:25922802

The prevalence of diabetes, dyslipidemias, and high blood pressure is increasing worldwide especially in low and middle income countries. World Health Organization has emphasized the importance of the assessment of the magnitude of the specific disease in each country. We determined the prevalence and determinant factors of high blood pressure, hyperglycemia, dyslipidemias and metabolic syndrome in Ethiopia. A community based survey was conducted from -April to June 2015 using WHO NCD STEPS instrument version 3.1. 2008. Multistage stratified systemic random sampling was used to select representative samples from 9 regions of the country. A total of 10,260 people aged 15-69 years participated in the study. Blood pressure (BP) was measured for 9788 individuals. A total of 9141 people underwent metabolic screening. The prevalence of raised blood pressure (SBP ≥140 and/or DBP ≥ 90 mmHg) was 15.8% (16.3% in females and 15.5% in males). The prevalence of diabetes mellitus (FBS ≥ 126 mg /dl) including those on medication was 3.2% (3.5% males and 3.0% females). The prevalence of impaired fasting glucose was 9.1% with ADA criteria and 3.8% with WHO criteria. Hypercholesterolemia was found in 5.2%, hypertriglyceridemia in 21.0%, high LDL cholesterol occurred in 14.1% and low HDL cholesterol occurred in 68.7%. The prevalence of metabolic syndrome using IDF definition was 4.8% (8.6% in females and vs. 1.8% in males). Advanced age, urban residence, lack of physical exercise, raised waist circumference, raised waist hip ratio, overweight or obesity, and total blood cholesterol were significantly associated with raised blood pressure (BP) and diabetes mellitus. Increased waist- hip ratio was an independent predictor of raised blood pressure, hyperglycemia and raised total cholesterol. Our study showed significantly high prevalence of raised blood pressure, hyperglycemia and dyslipidemia in Ethiopia. Community based interventions are recommended to control these risk factors.

An increased risk for Alzheimer's disease is associated with dyslipidemia and insulin resistance. A separate literature shows the genetic risk for developing Alzheimer's disease is strongly correlated to the presence of the E4 isoform of the apolipoprotein E carrier protein. Understanding how apolipoprotein E carrier protein, lipids, amyloid β peptides, glucose, central nervous system insulin, and peripheral insulin interact with one another in Alzheimer's disease is an area of increasing interest. Here, we will review the evidence relating apolipoprotein E carrier protein, lipids, and insulin action to Alzheimer's disease and Aβ peptides and then propose mechanisms as to how these factors might interact with one another to impair cognition and promote Alzheimer's disease.

To observe and compare the effects of grain-bean package, dietary fiber (DF) extracted from grain-bean package, and DF from grain corn on the blood lipids and fatty acid synthase (FAS) activity in high-fat, high-cholesterol feeding induced dyslipidemia rats, and observe its effects on regulation of sterol regulatory element protein-1c (SREBP-1c) mRNA expression in rat liver. Consolidation 50 SD rats of clean grade feeding adaptation for one week, randomly assigned into normal control group, hyperlipidemia model group, grain-bean package group, grain-bean package DF group and grain corn group. Feed with corresponding diets for 8 weeks, and measure the total cholesterol (TC), triglyceridaemia (TG), high density lipoprotein cholesterol (HDL-C), fasting blood glucose (FBG), FAS, SREBP-1c mRNA of all groups. Compared with control group, TC, TG, FBG levels of hyperlipidemia model group were significantly increased (P < 0.05). Compared with model group, TC, TG, FBG levels of grain-bean package group, grain-bean package DF group were significantly decreased, HDL-C levels significantly increased, and activity of FAS, regulation of SREBP-1c were significantly decreased (P < 0.05). The Grain-bean package dietary fiber can improve blood lipids levels of dyslipidemia rats, and decrease FAS activity and SREBP-1c mRNA expression.

Ursolic acid (UA) is a pentacyclic triterpenoid compound that naturally occurs in fruits, leaves and flowers of medicinal herbs. This study investigated the dose-response efficacy of UA (0.01 and 0.05%) on glucose metabolism, the polyol pathway and dyslipidemia in streptozotocin/nicotinamide-induced diabetic mice. Supplement with both UA doses reduced fasting blood glucose and plasma triglyceride levels in non-obese type 2 diabetic mice. High-dose UA significantly lowered plasma free fatty acid, total cholesterol and VLDL-cholesterol levels compared with the diabetic control mice, while LDL-cholesterol levels were reduced with both doses. UA supplement effectively decreased hepatic glucose-6-phosphatase activity and increased glucokinase activity, the glucokinase/glucose-6-phosphatase ratio, GLUT2 mRNA levels and glycogen content compared with the diabetic control mice. UA supplement attenuated hyperglycemia-induced renal hypertrophy and histological changes. Renal aldose reductase activity was higher, whereas sorbitol dehydrogenase activity was lower in the diabetic control group than in the non-diabetic group. However, UA supplement reversed the biochemical changes in polyol pathway to normal values. These results demonstrated that low-dose UA had preventive potency for diabetic renal complications, which could be mediated by changes in hepatic glucose metabolism and the renal polyol pathway. High-dose UA was more effective anti-dyslipidemia therapy in non-obese type 2 diabetic mice.

OBJECTIVE Cardiovascular disease (CVD) is the leading cause of death for women in the United States and is largely preventable. The American Heart Association has recently released evidence-based guidelines for the prevention of CVD in women; these include gender-specific recommendations for the management of dyslipidemia. This article reviews these recommendations and the evidence supporting them. DESIGN This was a qualitative review of a systematic literature search related to lipid guidelines for women and discussion of rationale and evidence for new clinical recommendations. MAIN RESULTS Lifestyle modifications are the cornerstone of lipid management. Substantial evidence from randomized clinical trials supports the use of low-density lipoprotein cholesterol–lowering therapy (primarily statins) in all high-risk women and the use of niacin or fibrates when high-density lipoprotein cholesterol is low or non-high-density lipoprotein cholesterol is elevated. Fewer data are available for women at lower or intermediate risk. CONCLUSIONS Encouragement of lifestyle modification and appropriate use of lipid-altering therapy will have a substantial impact on reducing the burden of cardiovascular disease in women.

A decade has passed since metabolic syndrome (MetS) was documented to be highly prevalent in the kingdom of Saudi Arabia. No follow-up epidemiologic study was done. This study aims to fill this gap. In this cross-sectional, observational study, a total of 2850 randomly selected Saudi adults aged 18–55 years were recruited. Subjects' information was generated from a database of more than 10,000 Saudi citizens from the existing Biomarkers Screening in Riyadh Program (RIYADH Cohort), Saudi Arabia. Anthropometrics included body mass index (BMI), blood pressure, as well as waist and hip circumferences. Fasting blood glucose and lipid profile were determined using routine laboratory procedures. The definition of ATP-III (NHANES III) was used for the diagnosis of the full MetS. The overall prevalence of complete MetS was 35.3% [Confidence-Interval (CI) 33.5–37.01]. Age-adjusted prevalence according to the European standard population is 37.0%. Low HDL-cholesterol was the most prevalent of all MetS risk factors, affecting 88.6% (CI 87.5–89.7) and hypertriglyceridemia the second most prevalent, affecting 34% (CI 32.3–35.7) of the subjects. The prevalence of the full MetS decreased from previous estimates but remains high, while dyslipidemia remains extremely high, affecting almost 90% of middle-aged Arabs. Screening for dyslipidemia among Saudi adults is warranted, especially among those most at risk. Scientific inquiry into the molecular causes of these manifestations should be pursued as a first step in the discovery of etiologic therapies. PMID:20730053

A total of 712 patients with dyslipidemia and 764 control subjects of CETP gene polymorphism at rs12149545, rs3764261, rs1800775, rs711752, rs708272, rs289714, rs5882, and rs1801706 loci were studied by the Snapshot method, linkage disequilibrium analysis and haplotype construction. The results are as follows: (1) the minor allele of eight loci of frequencies in the two groups were different from other results of similar studies in other countries; (2) In the linear regression analysis, the HDL-C levels of rs708272 TT, rs1800775 AA, rs289714 CC and rs711752 AA genotypes were significantly higher than those of other genotypes, however, the rs3764261 GG and rs12149545 GG genotypes were significantly lower than those of other genotypes in the two ethnic groups. The HDL-C levels of the rs12149545 GG genotype were lower than those of other genotypes; (3) in the control group, the rs708272 CT genotype of TG levels were lower than in the CC genotype, the T genotype of LDL-C levels were lower than in the CC genotype, and the HDL-C levels were higher than in the CT genotype; the rs1800775 AC genotype of TG levels were higher than in the AA genotype, the rs711752 AG genotype of TG levels were lower than in the GG genotype, the AA genotype LDL-C levels were lower than in the GG genotype, and the HDL-C levels were higher than in the AG genotype; the rs1800775 AC genotype of TG levels were higher than in the AA genotype. In the dyslipidemia group, the rs708272 TT genotype of TC and LDL-C levels were higher than in the CT genotype and the rs3764261 TT genotype of TC levels were higher than in the GG genotype. The rs711752 AA genotype of TC and LDL-C levels were higher than in the AG genotype, and the rs12149545 AA genotype of TC and LDL-C levels were higher than in the GG genotype; (4) perfect Linkage

Objective To determine levels of cholesterol lipoproteins and prevalence of dyslipidemias in urban Asian Indians. Methods Population based 6123 subjects (men 3388) were evaluated. Mean±1SD of various cholesterol lipoproteins (total, HDL, LDL and non-HDL cholesterol) and triglycerides were reported. Subjects were classified according to US National Cholesterol Education Program. Results Age-adjusted levels in men and women were cholesterol total 178.4 ± 39 and 184.6 ± 39, HDL 44.9 ± 11 and 51.1 ± 11, LDL 102.5 ± 33 and 106.2 ± 33, total:HDL 4.15 ± 1.2 and 3.79 ± 1.0 and triglycerides 162.5 ± 83 and 143.7 ± 83 mg/dl. Age-adjusted prevalence (%) in men and women, respectively were, total cholesterol ≥200 mg/dl 25.1 and 24.9, LDL cholesterol ≥130 mg/dl 16.3 and 15.1 and ≥100 mg/dl 49.5 and 49.7, HDL cholesterol <40/<50 mg/dl 33.6 and 52.8, total:HDL cholesterol ≥4.5 29.4 and 16.8, and triglycerides ≥150 mg/dl 42.1 and 32.9%. Cholesterol level was significantly greater in subjects with better socioeconomic status, body mass index and waist circumference while triglycerides were more among those with high socioeconomic status, fat intake, body mass index and waist circumference (p < 0.05). Hypercholesterolemia awareness (15.6%), treatment (7.2%) and control (4.1%) were low. Conclusions Mean cholesterol and LDL cholesterol are low and triglycerides were high in urban Asian Indians. Most prevalent dyslipidemias are borderline high LDL, low HDL and high triglycerides. Subjects with high socioeconomic status, high fat intake and greater adiposity have higher total and LDL cholesterol and triglyceride and lower HDL cholesterol. PMID:24973832

Human exposure to organic pollutants (some of them also called endocrine disruptors) can be associated with adverse metabolic health outcomes including type 2 diabetes. The goal of this study was to compare the urine levels of bisphenol A and phthalate metabolites in subgroups of patients with metabolic syndrome composed of patients with and without three important components of metabolic syndrome (hypertension, dyslipidemia and diabetes). We have investigated 24 hr urine samples of 168 patients with metabolic syndrome from the Metabolic Outpatient Department of General University Hospital in Prague. Using standard metabolic syndrome criteria, we classified patients as dyslipidemic (n=87), hypertensive (n=96), and type 2 diabetic (n=58). Bisphenol A and 15 metabolites of phthalates were evaluated in relation to creatinine excretion. Samples were analysed with enzymatic cleavage of glucuronide using ultra-high-performance liquid chromatography-electrospray ionization tandem mass spectrometry in one laboratory with external quality control. Four metabolites, mono-n-butyl phthalate, mono-(2-ethyl-5-hydroxyhexyl) phthalate, mono-(2-ethyl-5-oxohexyl) phthalate, and mono-(2-ethyl-5-carboxypentyl) phthalate showed significantly higher levels in diabetic compared to non-diabetic patients (p<0.001, p=0.002, p=0.002, and p=0.005, respectively). The differences remained significant after adjustment to hypertension, dyslipidemia, age, and BMI. No difference was found between either the hypertensive and non-hypertensive or dyslipidemic and non-dyslipidemic patients. There was no significant relation of bisphenol A level to diabetes, hypertension, dyslipidemia, age, and BMI. Urine levels of four phthalate metabolites were significantly higher in type 2 diabetics independently on specified predictors. Phthalate levels can be in relation to beta cell dysfunction in type 2 diabetic patients but this study is not able to show if the relation is causal. Copyright© by the National

Maternal nutrition modulates fetal metabolic programming and development later. Maternal dyslipidemia effects on oxidative stress (OS) in offsprings and its modulation by dietary fatty acids over generations remains to be elucidated. The objective of present study was to assess the long-term (three generations) effect of omega-3 fatty acids on OS under dyslipidemia. Weanling female Wistar rats were fed with control diet (7% lard), high fat diet (35% lard, HFL), high fat with fish oil (21% fish oil + 14% lard, HFF), high fat with canola oil (21% canola oil + 14% lard, HFC) and high fat with sunflower oil (21% sunflower oil + 14% lard, HFS). Following 60 days feeding, the female rats were mated with sexually matured males (fed normal chow diet) and continued with the above diet regimen during pregnancy and lactation. The pups after lactation were continued with their maternal diet for 60 days and subjected to mating and feeding trial as above for two generations. Serum lipid profiles, OS markers (lipid peroxidation, nitric oxide release and protein carbonyl) and antioxidant defence enzymes (catalase, SOD, glutathione peroxidase and glutathione transferase) were assessed in serum, liver and uterus of rats fed on experimental and control diets for three generations. Feeding HFL diet increased blood lipids, OS and lowered the antioxidant enzymes activity in serum, liver and uterus (p < 0.05). The reduction in the antioxidant enzymes in HFL group were higher in third followed by second generation compared to first generation (p < 0.05). Omega-3 fatty acids prevented the dyslipidemia induced loss of antioxidant enzyme activities in serum, liver and uterus. Our data show for the first time that offsprings born to dyslipidemic mothers' exhibit diminished enzymatic antioxidant defence and its progressive reduction in future generation, and dietary omega-3 fatty acids restore the enzymatic antioxidant defence in offsprings and suppress the markers of OS.

Obesity and type 2 diabetes mellitus (T2DM) are occurring at epidemic-like rates, and these epidemics appear to have emerged largely from changes in daily diet. In the present study, we compared effects of high-fat diet (HFD) and fructose-rich diet (FRD) in WBN/Kob-Lepr fa (WBKDF) rats that spontaneously develop obesity, dyslipidemia and T2DM. After a 4-week feeding of each diet, WBKDF-HFD and WBKDF-FRD rats exhibited aggravated obesity and dyslipidemia compared with WBKDF rats fed standard diet (STD). In contrast, hyperglycemia developed in WBKDF-STD rats was significantly inhibited in WBKDF-FRD rats, but not in WBKDF-HFD rats. The present study demonstrated that the 4-week feeding of HFD and FRD caused diet-induced obesity with a distinct phenotype in the glucose metabolism in WBKDF rats.

The publication of the 2013 American College of Cardiology/American Heart Association guidelines on the treatment of high blood cholesterol has had a strong impact due to the paradigm shift in its recommendations. The Spanish Interdisciplinary Committee for Cardiovascular Disease Prevention and the Spanish Society of Cardiology reviewed this guideline and compared it with current European guidelines on cardiovascular prevention and dyslipidemia management. The most striking aspect of the American guideline is the elimination of the low-density lipoprotein cholesterol treat-to-target strategy and the adoption of a risk reduction strategy in 4 major statin benefit groups. In patients with established cardiovascular disease, both guidelines recommend a similar therapeutic strategy (high-dose potent statins). However, in primary prevention, the application of the American guidelines would substantially increase the number of persons, particularly older people, receiving statin therapy. The elimination of the cholesterol treat-to-target strategy, so strongly rooted in the scientific community, could have a negative impact on clinical practice, create a certain amount of confusion and uncertainty among professionals, and decrease follow-up and patient adherence. Thus, this article reaffirms the recommendations of the European guidelines. Although both guidelines have positive aspects, doubt remains regarding the concerns outlined above. In addition to using risk charts based on the native population, the messages of the European guideline are more appropriate to the Spanish setting and avoid the possible risk of overtreatment with statins in primary prevention.

Background There is a physiologic elevation of total cholesterol (TC) and triglycerides (TG) during pregnancy. Some authors define dyslipidemia (DLP) in pregnant women when TC, LDL and TG concentrations are above the 95th percentile (p95%) and HDL concentration is below the 5th percentile (P5%) for gestational age (GA). Objective To compare the prevalence of DLP in pregnant women using percentiles criteria with the V Brazilian Guidelines on Dyslipidemia and the association with maternal and fetal outcomes. Results Pregnant women with high-risk conditions, aged 18-50 years, and at least one lipid profile during pregnancy was classified as the presence of DLP by two diagnostic criteria. Clinical and laboratorial data of mothers and newborns were evaluated. Conclusion 433 pregnant women aged 32.9 ± 6.5 years were studied. Most (54.6%) had lipid profile collected during third trimester. The prevalence of any lipid abnormalities according to the criteria of the National Guidelines was 83.8%: TC ≥ 200 mg/dL was found in 49.9%; LDL ≥ 160 mg/dL, in 14.3%, HDL ≤ 50 mg/dL in 44.4% and TG ≥ 150 mg/dL in 65.3%. Any changes of lipid according to percentiles criteria was found in 19.6%: elevation above the P95% for TC was found in 0.7%; for LDL, 1.7%; for TG 6.4% and HDL lower than the P5% in 13%. The frequency of comorbidity: hypertension, diabetes, smoking, obesity and preeclampsia was similar among pregnant women when DLP was compared by both criteria. Conclusion The prevalence of DLP during pregnancy varies significantly depending on the criteria used, however none demonstrated superiority in association with comorbidities. PMID:28591252

Update on marine omega-3 fatty acids: management of dyslipidemia and current omega-3 treatment options.

PubMed

Weintraub, Howard

2013-10-01

Low-density lipoprotein cholesterol (LDL-C) is currently the primary target in the management of dyslipidemia, and statins are first-line pharmacologic interventions. Adjunct therapy such as niacins, fibrates, bile acid sequestrants, or cholesterol absorption inhibitors may be considered to help reduce cardiovascular risk. This review discusses the need for alternative adjunct treatment options and the potential place for omega-3 fatty acids as such. The cardiovascular benefits of fish consumption are attributed to the omega-3 fatty acids eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), and a variety of omega-3 fatty acid products are available with varied amounts of EPA and DHA. The product types include prescription drugs, food supplements, and medical foods sourced from fish, krill, algal and plant oils or purified from these oils. Two prescription omega-3 fatty acids are currently available, omega-3 fatty acid ethyl esters (contains both EPA and DHA ethyl esters), and icosapent ethyl (IPE; contains high-purity EPA ethyl ester). A pharmaceutical containing free fatty acid forms of omega-3 is currently in development. Omega-3 fatty acid formulations containing EPA and DHA have been shown to increase LDL-C levels while IPE has been shown to lower triglyceride levels without raising LDL-C levels, alone or in combination with statin therapy. In addition, recent studies have not been able to demonstrate reduced cardiovascular risk following treatment with fibrates, niacins, cholesterol absorption inhibitors, or omega-3 fatty acid formulations containing both EPA and DHA in statin-treated patients; thus, there remains a need for further cardiovascular outcomes studies for adjunct therapy.

Correlation between non-alcoholic fatty liver disease (NAFLD) and dyslipidemia in type 2 diabetes.

PubMed

Krishan, Saini

2016-01-01

Non-alcoholic fatty liver means the presence of hepatosteatosis without significant alcohol consumption; it is strongly associated with obesity and metabolic disorder like type 2 diabetes and dyslipideamia. NASH may progress to advanced stages of hepatic fibrosis and cirrhosis. Increased body mass index and viral genotype contribute to steatosis in chronic hepatitis. The sonographic features of NAFLD include the presence of bright hepatic echotexture deep attenuation, and vascular blurring either singly or in combination. Dyslipidemia in patients with NAFLD is atherogenic in nature and it is characterized by increased levels of serum triglycerides and decreased levels of HDL cholesterol. Statins are potent lipid-lowering agents which decrease LDL cholesterol by 20-60%, decrease triglycerides by 10-33% and increase HDL cholesterol by 5-10% for the patients with NAFLD.

Some anthropometric measurements show a greater capacity than others to identify the presence of cardiovascular risk factors. This study estimated the magnitude of the association of different anthropometric indicators of obesity with hypertension, dyslipidemia, and prediabetes (altered fasting plasma glucose and/or glycosylated hemoglobin). Cross-sectional analysis of information collected from 2022 participants in the PREDAPS study (baseline phase). General obesity was defined as body mass index ≥ 30kg/m 2 and abdominal obesity was defined with 2 criteria: a) waist circumference (WC) ≥ 102cm in men/WC ≥ 88cm in women, and b) waist-height ratio (WHtR) ≥ 0.55. The magnitude of the association was estimated by logistic regression. Hypertension showed the strongest association with general obesity in women (OR, 3.01; 95%CI, 2.24-4.04) and with abdominal obesity based on the WHtR criterion in men (OR, 3.65; 95%CI, 2.66-5.01). Hypertriglyceridemia and low levels of high-density lipoprotein cholesterol showed the strongest association with abdominal obesity based on the WHtR criterion in women (OR, 2.49; 95%CI, 1.68-3.67 and OR, 2.70; 95%CI, 1.89-3.86) and with general obesity in men (OR, 2.06; 95%CI, 1.56-2.73 and OR, 1.68; 95%CI, 1.21-2.33). Prediabetes showed the strongest association with abdominal obesity based on the WHtR criterion in women (OR, 2.48; 95%CI, 1.85-3.33) and with abdominal obesity based on the WC criterion in men (OR, 2.33; 95%CI, 1.75-3.08). Abdominal obesity indicators showed the strongest association with the presence of prediabetes. The association of anthropometric indicators with hypertension and dyslipidemia showed heterogeneous results. Copyright © 2017 Sociedad Española de Cardiología. Published by Elsevier España, S.L.U.

Atherogenic dyslipidemia (AD), characterized by high plasma triglycerides and low HDL particles, is considered one of the main effectors of vascular damage associated with obesity, metabolic syndrome (MS) and type 2 diabetes. Adipocyte fatty acid-binding protein (FABP4) plasma concentrations have been linked to metabolic alterations that are associated with adiposity. The aim of the present study was to prospectively analyze the predictive value of baseline FABP4 plasma concentrations for the development of AD. In the frame of the PREDIMED study, a multicenter dietary interventional trial, we prospectively measured the baseline plasma FABP4 levels and AD incidence over a six-year follow-up period (median 4 [IQR, 3-5 years]) in 578 volunteers who visited their general practitioners because of their cardiovascular risk factors. During follow-up, 103 participants developed AD. Baseline plasma FABP4 levels were associated with new onset AD over the follow-up period (OR 1.03 [95% IC: 1.00-1.05], p=0.020). This increased risk was observed in women but not in men. Among women, those in the highest tertile of FABP4 had a 2.54-fold increased relative risk of developing AD compared to the lowest tertile (HR 2.54 [95% CI, 1.31-4.93], p for trend=0.008). Elevated plasma FABP4 concentrations should be considered as a potential marker of metabolic derangement, which may predict the development of AD in women. Copyright © 2012 Elsevier Ireland Ltd.

The use of monosodium glutamate (MSG) as a flavor enhancer spans more than 100 y and there are many studies indicating the safety of general use of MSG. Recently, however, Collison et al. (2010) reported a two-generation study with a low dose of MSG that caused abdominal obesity, insulin resistance and dyslipidemia in mice. Due to public health concerns over metabolic syndrome, their report merits careful analysis. The present study attempted to repeat the Collison et al. findings. Groups of male or female C57BL/6J mice were fed a control diet or one supplemented with high-fructose corn syrup (HFCS) at a level of 20%. Drinking water control was provided or treatment groups were given 0.064% MSG solution (w/v). Diets and MSG administration continued throughout mating and during gestation and lactation periods. To further investigate the effects of ingestion of MSG, the offspring were continued on the same dosing conditions until they reached 32 wk of age. MSG administration in mice fed a normal or a HFCS diet throughout gestation and for 32 wk after birth, did not affect growth, girth size, abdominal fat weight or body composition. This study reports that MSG did not trigger insulin resistance, dyslipidemia or hepatic steatosis, regardless of the diet, not reproducing the results of the above-mentioned study (Collison et al., 2010).

Background Body mass index (BMI), waist circumference (WC), and waist-to-hip ratio (WHR) are used in screening and predicting obesity in adults. However, the best identifier of metabolic complications in children with obesity remains unclear. This study evaluated lipid profile distribution and investigated the best anthropometric parameter in association with lipid disorders in children with obesity. Methods A total of 2243 school children aged 7–17 years were enrolled in Guangzhou, China, in 2014. The anthropometric indices and lipid profiles were measured. Dyslipidemia was defined according to the US Guidelines for Cardiovascular Health and Risk Reduction in Children and Adolescents. The association between anthropometry (BMI, WC, and WHR) and lipid profile values was examined using chi-square analysis and discriminant function analysis. Information about demography, physical activity, and dietary intake was provided by the participant children and their parents. Results Children aged 10–14 and 15–17 years old generally had higher triglyceride values but lower median concentration of total cholesterol, high-density lipoprotein cholesterol, and low-density lipoprotein cholesterol compared with children aged 7–9 years old (all P < 0.001). These lipid parameters fluctuated in children aged 10–14 years old. The combination of age groups, BMI, WC and WHR achieved 65.1% accuracy in determining dyslipidemic disorders. BMI correctly identified 77% of the total dyslipidemic disorders in obese children, which was higher than that by WHR (70.8%) (P< 0.05). Conclusion The distribution of lipid profiles in Chinese children differed between younger and older age groups, and the tendency of these lipid levels remarkably fluctuated during 10 to 14 years old. BMI had better practical utility in identifying dyslipidemia among school-aged children with obesity compared with other anthropometric measures. PMID:26963377

The publication of the 2013 American College of Cardiology/American Heart Association guidelines on the treatment of high blood cholesterol has had a strong impact due to the paradigm shift in its recommendations. The Spanish Interdisciplinary Committee for Cardiovascular Disease Prevention and the Spanish Society of Cardiology reviewed this guideline and compared it with current European guidelines on cardiovascular prevention and dyslipidemia management. The most striking aspect of the American guideline is the elimination of the low-density lipoprotein cholesterol treat-to-target strategy and the adoption of a risk reduction strategy in 4 major statin benefit groups. In patients with established cardiovascular disease, both guidelines recommend a similar therapeutic strategy (high-dose potent statins). However, in primary prevention, the application of the American guidelines would substantially increase the number of persons, particularly older people, receiving statin therapy. The elimination of the cholesterol treat-to-target strategy, so strongly rooted in the scientific community, could have a negative impact on clinical practice, create a certain amount of confusion and uncertainty among professionals, and decrease follow-up and patient adherence. Thus, this article reaffirms the recommendations of the European guidelines. Although both guidelines have positive aspects, doubt remains regarding the concerns outlined above. In addition to using risk charts based on the native population, the messages of the European guideline are more appropriate to the Spanish setting and avoid the possible risk of overtreatment with statins in primary prevention.

To assess the prevalence of lipid abnormalities, with special emphasis on atherogenic dyslipidemia and its relationship with chronic complications in patients with type 1 diabetes mellitus (T1DM). Cross-sectional study including all patients aged 18 and over, diagnosed of T1DM attending the outpatient clinic at Hospital del Mar and Hospital de Granollers, in Barcelona, during 2008. Of the 291 enrolled patients, 17.2 and 7.9% had high density lipoproteins (HDL) cholesterol<40 mg/dL (men) or<50mg/dL (women) and triglycerides>150 mg/dL, respectively. Hypoalphalipoproteinemic patients had a higher prevalence of peripheral neuropathy (28 vs. 7.1%, P<.001), macroalbuminuria (14 vs. 2.5%, P<.001) and higher concentrations of triglycerides (107.5 [55.8] vs. 82.7 [36] mg/dL, P<.0001) compared with those with normal/high HDL cholesterol levels. Hypertriglyceridemia was associated with increasing age (43.6 [11.2] vs. 37.6 [11.8] yr, P<.02), higher prevalence of hypertension (47.8 vs. 22.8%, P<.008), metabolic syndrome (82.6 vs. 22%, P<.001) and microangiopathic complications, lower insulin sensitivity (6.75 [2.1] vs. 8.54 [2.6] mg/Kg(-1)/min(-1), P<.004) compared with the normotriglyceridemic group. One in 5 patients with T1DM has hypoalphalipoproteinemia or hypertriglyceridemia and these conditions are associated with 3 fold-increase microangiopathy. Thus, in these patients glycemic and blood pressure but also lipid profile control must be optimum. Copyright © 2013 Elsevier España, S.L. All rights reserved.

The main dietary sources of trans fatty acids are partially hydrogenated vegetable oils (PHVO), and products derived from polyunsaturated fatty acid biohydrogenation (PUFA-BHP) in ruminants. Trans fatty acid intake has historically been associated with negative effects on health, generating an anti-trans fat campaign to reduce their consumption. The profiles and effects on health of PHVO and PUFA-BHP can, however, be quite different. Dairy products naturally enriched with vaccenic and rumenic acids have many purported health benefits, but the putative benefits of beef fat naturally enriched with PUFA-BHP have not been investigated. The objective of the present experiment was to determine the effects of beef peri-renal fat (PRF) with differing enrichments of PUFA-BHP on lipid and insulin metabolism in a rodent model of dyslipidemia and insulin resistance (JCR:LA-cp rat). The results showed that 6 weeks of diet supplementation with beef PRF naturally enriched due to flaxseed (FS-PRF) or sunflower-seed (SS-PRF) feeding to cattle significantly improved plasma fasting insulin levels and insulin sensitivity, postprandial insulin levels (only in the FS-PRF) without altering dyslipidemia. Moreover, FS-PRF but not SS-PRF attenuated adipose tissue accumulation. Therefore, enhancing levels of PUFA-BHP in beef PRF with FS feeding may be a useful approach to maximize the health-conferring value of beef-derived fats.

Obesity can cause or worsen asthma. Compared with common asthma, obese asthma is difficult to control. Statins are effective serum cholesterol-lowering agents in clinical practice, and they also have anti-inflammatory properties, which in theory are potentially beneficial in asthma. Many studies have shown that simvastatin has good therapeutic effect in animal models of asthma. However, the therapeutic effect and action mechanism of simvastatin for obese asthma remain unclear. Leptin, a satiety hormone, is in positive correlation with total body fat mass and may also play a significant role in the pathogenesis of asthma. In this study, we use the method of high-fat diet and ovalbumin (OVA) sensitization and challenge to establish the mouse model of obesity and asthma, and find that obese asthmatic mice has higher levels of glucose, lipid and leptin in serum, and neutrophil percentage in bronchoalveolar lavage fluid (BALF), and more severe airway inflammation and structural changes in lung tissues than non-obese asthmatic mice, and respond poorly to dexamethasone treatment, which indicates that obese asthma might belong to steroid-resistant (SR) asthma. Simvastatin treatment reduces the levels of glucose, lipid, leptin and neutrophil percentage, and improves airway inflammation and remodeling, which can be as a potential therapeutic target used in the treatment of obese asthma in humans. Correlation analysis shows that there is positive correlation between neutrophil percentage and serum leptin/cholesterol level, which indicates that the therapeutic efficacy of simvastatin on obese asthma might be associated with improving dyslipidemia and decreasing leptin level.

It is still unclear whether carbohydrate consumption is associated with cardiovascular disease (CVD) risk. Genetic susceptibility might modify the associations between dietary intakes and disease risk. The aim was to examine the association between the consumption of carbohydrate-rich foods (vegetables, fruits and berries, juice, potatoes, whole grains, refined grains, cookies and cakes, sugar and sweets, and sugar-sweetened beverages) and the risk of incident ischemic CVD (iCVD; coronary events and ischemic stroke), and whether these associations differ depending on genetic susceptibility to dyslipidemia. Among 26,445 individuals (44-74 years; 62% females) from the Malmö Diet and Cancer Study cohort, 2,921 experienced an iCVD event during a mean follow-up time of 14 years. At baseline, dietary data were collected using a modified diet history method, and clinical risk factors were measured in 4,535 subjects. We combined 80 validated genetic variants associated with triglycerides and HDL-C or LDL-C, into genetic risk scores and examined the interactions between dietary intakes and genetic risk scores on the incidence of iCVD. Subjects in the highest intake quintile for whole grains had a 13% (95% CI: 3-23%; p-trend: 0.002) lower risk for iCVD compared to the lowest quintile. A higher consumption of foods rich in added sugar (sugar and sweets, and sugar-sweetened beverages) had a significant cross-sectional association with higher triglyceride concentrations and lower HDL-C concentrations. A stronger positive association between a high consumption of sugar and sweets on iCVD risk was observed among those with low genetic risk score for triglycerides (p-interaction=0.05). In this prospective cohort study that examined food sources of carbohydrates, individuals with a high consumption of whole grains had a decreased risk of iCVD. No convincing evidence of an interaction between genetic susceptibility for dyslipidemia, measured as genetic risk scores of dyslipidemia

Background: Beyond nutritional values are the pharmacological potentials of cassava comparative with other staple carbohydrate plant-based foods such as wheat. The knowledge of applicability to diabetes and its cardiovascular complications management seems not just limited but unacknowledged. As a preliminary study, a community’s knowledge of pharmacological value of cassava is investigated. Methods: Descriptive observational study using questionnaire-based “cross-sectional” survey was conducted. 136 Participants completed the survey and 101 respondents were selected for evaluation. Open-ended questions were used qualitatively to generate experience and view cassava values for diabetes and dyslipidemia. While categorical (yes or no) questions were used quantitatively to generate numerical results for diabetes, critical reanalysis of a report data was performed, especially comparing carbohydrate/fiber and fat/fiber ratios of cassava with wheat in view of dyslipidemia. Result: On the positive side, 42% of the participants believe that cassava has medicinal values. This includes 6% (among the 42) who believes that the plant is useful in treating diabetes and 24% who do not know it may be useful in diabetes management. Critical review showed that cassava may contribute up to sixteen times more fiber and four times less digestible sugar, as well as carbohydrate/fiber and fat/fiber ratios being 14 and 55 times less than wheat. Conclusion: There is evidence that relative to wheat flour meal, for instance, cassava contributes less fat and much more fiber. Since fat is pro-obesity, which in turn is pro-diabetic/metabolic syndrome; and fiber is anti-dyslipidemic; cassava has pharmacological values to be appreciated over some carbohydrate plant-based foods.

Background. Dyslipidemia has been well-known as a common metabolic disorder contributing to cardiovascular disease. The aim of this study was to evaluate the effect of the Pinus koraiensis needle extracts (PKE) on the blood cholesterol and oxidative stress. Method. We conducted a 12-week randomized, double-blinded controlled trial to examine the effect of PKE on blood lipid profiles in adults with borderline dyslipidemia. Thirty-three eligible persons were recruited and randomly assigned into PKE (n = 20) and placebo groups (n = 13). Serum lipids including total cholesterol, low-density lipoprotein- (LDL-) cholesterol, high-density lipoprotein- (HDL-) cholesterol, very low-density lipoprotein- (VLDL-) cholesterol, and triglyceride were measured before and after trial. Serum insulin, glucose, and antioxidant indicators were also analyzed before and after trial and anthropometry and blood pressure were measured every 4 weeks. Results. After 12 weeks, PKE statically significant decreases in systolic blood pressure (p < 0.05) and waist circumference (p < 0.05) were observed. Also, VLDL-cholesterol significantly decreased (from 24.4 ± 10.0 mg/dL at baseline to 18.4 ± 4.1 mg/dL after 12 weeks) (p < 0.05) and superoxide dismutase (SOD) increased (6.12 ± 0.41 U/mL to 9.06 ± 0.62 U/mL) (p < 0.01) in PKE group. However, after adjustment with WC, VLDL-cholesterol was not significant between groups (p = 0.095) and while SOD remained significant between groups (p = 0.013). Conclusion. The results show that PKE was effective in improving the superoxide dismutase in the individuals with borderline dyslipidemia. PMID:27610187

The MightyMedic (Multidisciplinary International Group for Hemapheresis TherapY and MEtabolic DIsturbances Contrast) Working Group has been founded in 2013. The leading idea was to establish an international network of interdisciplinary nature aimed at working to cross national borders research projects, clinical trials, educational initiatives (meetings, workshops, summer schools) in the field of metabolic diseases, namely hyperlipidemias, and diabetes, preventive cardiology, and atherosclerosis. Therapeutic apheresis, its indications and techniques, is a parallel field of investigation. The first on-line survey of the Group has been completed in the first half of 2014. The survey included # 24 Centers in Italy, Germany, Greece, UK, Sweden, Japan and USA. Relevant data have been collected on current practice in diagnosis, therapy and follow-up of dyslipidemias. 240 subjects with hyperlipidemia and treated with lipoprotein apheresis have been reported in the survey, but a large percentage of patients (35%) who could benefit from this therapeutic option are still treated by conventional drug approach. Genetic molecular diagnosis is performed in only 33% of patients while Lipoprotein(a) (Lp(a)) is included in cardiovascular disease risk assessment in 71% of participating Centers. New detailed investigations and prospective multicenter studies are needed to evaluate changes induced by the impact of updated indications and strategies, as well as new treatment options, targeting standardization of therapeutic and diagnostic approaches.

ABSTRACT OBJECTIVE To determine the distribution of total cholesterol, LDL cholesterol, HDL cholesterol, and triglycerides in Brazilian adolescents, as well as the prevalence of altered levels of such parameters. METHODS Data from the Study of Cardiovascular Risks in Adolescents (ERICA) were used. This is a country-wide, school-based cross-sectional study that evaluated 12 to 17-year old adolescents living in cities with over 100,000 inhabitants. The average and distribution of plasma levels of total cholesterol, LDL cholesterol, HDL cholesterol, and triglycerides were evaluated. Dyslipidemia was determined by levels of total cholesterol ≥ 170 mg/dl, LDL cholesterol ≥ 130 mg/dl, HDL cholesterol < 45 mg/dL, or triglycerides ≥ 130 mg/dl. The data were analyzed by gender, age, and regions in Brazil. RESULTS We evaluated 38,069 adolescents – 59.9% of females, and 54.2% between 15 and 17 years. The average values found were: total cholesterol = 148.1 mg/dl (95%CI 147.1-149.1), HDL cholesterol = 47.3 mg/dl (95%CI 46.7-47.9), LDL cholesterol = 85.3 mg/dl (95%CI 84.5-86.1), and triglycerides = 77.8 mg/dl (95%CI 76.5-79.2). The female adolescents had higher average levels of total cholesterol, LDL cholesterol, and HDL cholesterol, without differences in the levels of triglycerides. We did not observe any significant differences between the average values among 12 to 14 and 15- to 17-year old adolescents. The most prevalent lipid alterations were low HDL cholesterol (46.8% [95%CI 44.8-48.9]), hypercholesterolemia (20.1% [95%CI 19.0-21.3]), and hypertriglyceridemia (7.8% [95%CI 7.1-8.6]). High LDL cholesterol was found in 3.5% (95%CI 3.2-4.0) of the adolescents. Prevalence of low HDL cholesterol was higher in Brazil’s North and Northeast regions. CONCLUSIONS A significant proportion of Brazilian adolescents has alterations in their plasma lipids. The high prevalence of low HDL cholesterol and hypertriglyceridemia, especially in Brazil’s North and Northeast regions

Objective: To describe the various risk factors and identify the characteristics of ischemic stroke in diabetic patients. Method: A retrospective study carried out at King Fahd Hospital of the University in Al-Khobar, kingdom of Saudi Arabia from February 2010 to December 2015. Statistical analysis was performed by the Statistical Package for the Social Sciences (version 22.0, SPSS Inc, Chicago, IL, USA). Results: One hundred and twenty-seven diabetic patients with ischemic stroke were compared with 127 non-diabetics. Mean age was 61±13.6 (mean±SD) years for diabetics and 60±16.6 years for non-diabetics. There were 68.5% male in the diabetic group and 62.2% in the non-diabetic group. Small vessel occlusion was the most common subtype (41.7%) in diabetics and stroke of undetermined etiology (32%) in non-diabetics. Dyslipidemia was significantly more prevalent in diabetics as compared with non-diabetics. Conclusion: Our study found significant differences in characteristics of ischemic stroke in diabetics compared with non-diabetics with dyslipidemia, microangiopathy, and lacunar infarction being more frequent. Further epidemiological studies are required to understand the characteristics of strokes in diabetics. PMID:28064326

In this paper, the researchers collected visceral adipose tissue from the Uygur population, which were divided into two groups: the normal control group (NC, n = 50, 18.0 kg/m2 ≤ BMI ≤ 23.9 kg/m2) and the obese group (OB, n = 45, BMI ≥ 28 kg/m2), and then use real-time PCR to detect the mRNA expression level of key genes involved in inflammation signaling pathway. The findings suggest that, in obese status, the lower expression level of A2bAR, KLF4, and KLF15 of visceral adipose tissue may correlate with obese-dyslipidemia induced inflammation in Uygur population.

Dyslipidemia is a major risk factor for cardiovascular events. The prognostic importance of lipoproteins in patients with atrial fibrillation is not well understood. We aimed to explore the association between apolipoprotein A1 (ApoA1) and B (ApoB) and cardiovascular events in patients with atrial fibrillation receiving oral anticoagulation. Using data from the ARISTOTLE (Apixaban for Reduction in Stroke and Other Thromboembolic Events in Atrial Fibrillation) trial, ApoA1 and ApoB plasma levels were measured at baseline in 14 884 atrial fibrillation patients. Median length of follow-up was 1.9 years. Relationships between continuous levels of ApoA1 and ApoB and clinical outcomes were evaluated using Cox models adjusted for cardiovascular risk factors, medication including statins, and cardiovascular biomarkers. A composite ischemic outcome (ischemic stroke, systemic embolism, myocardial infarction, and cardiovascular death) was used as the primary end point. Median (25th, 75th) ApoA1 and ApoB levels were 1.10 (0.93, 1.30) and 0.70 g/L (0.55, 0.85), respectively. In adjusted analyses, higher levels of ApoA1 were independently associated with a lower risk of the composite ischemic outcome (hazard ratio, 0.81; P <0.0001). Similar results were observed for the individual components of the composite outcome. ApoB was not significantly associated with the composite ischemic outcome ( P =0.8240). Neither apolipoprotein was significantly associated with major bleeding. There was no interaction between lipoproteins and randomized treatment for the primary outcome (both P values ≥0.2448). In patients with atrial fibrillation on oral anticoagulation, higher levels of ApoA1 were independently associated with lower risk of ischemic cardiovascular outcomes. Investigating therapies targeting dyslipidemia may thus be useful to improve cardiovascular outcomes in patients with atrial fibrillation. URL: http://www.clinicaltrials.gov.

Low-density lipoprotein cholesterol (LDL-C) is the primary target of lipid-lowering therapy in people at risk for cardiovascular diseases. Mipomersen inhibits apolipoprotein B-100 (apoB) synthesis and causes reduction in LDL-C by reducing apoB. We aimed to perform a meta-analysis of all published randomized controlled trials comparing safety and efficacy of mipomersen with placebo in adults with dyslipidemia. We searched PUBMED, CENTRAL, and EMBASE from inception through March 2014 and used random-effects model to compute the effect size. We identified 8 randomized controlled trials (n = 462). Mipomersen compared with placebo significantly reduced LDL-C by 32.37% (95% confidence interval, 25.55-39.18; P < .00001), total cholesterol by 24.18% (18.54-29.83; P < .00001), very low-density lipoprotein cholesterol by 21.59% (9.16-34.02; P = .0007), non-high-density lipoprotein cholesterol (HDL-C) by 30.83% (23.92-37.74; P < .00001), and triglycerides by 36.26% (22-50.54; P < .00001). It also significantly reduced apoB, lipoprotein(a), and apolipoprotein A1. However, mipomersen did not significantly change HDL-C levels. In safety analysis, mipomersen compared with placebo increased the risks of injection-site reaction (risk ratio, 2.05; 95% confidence interval, 1.39-3.04; P = .0003), flu-like symptoms (1.63; 1.22-2.17; P = .0008), alanine aminotransferase ≥3X upper limit of normal (4.44; 1.67-11.86; P = .003), and hepatic steatosis (3.85, 1.39-10.67; P = .01). The risks of alanine aminotransferase ≥10X upper limit of normal did not reach statistical significance (1.57; 0.32-7.6, P = .58). Mipomersen resulted in a significant improvement in lipid parameters except for HDL-C and increased the risks of injection-site reactions, flu-like symptoms, and hepatic steatosis compared with placebo.

Guidelines propose additional therapy to statin to treat elevated triglycerides (TG) and low high-density lipoprotein cholesterol (HDLC) in dyslipidemic patients. We evaluated the effects of new fixed-dose combinations (FDC) of fenofibrate/simvastatin on plasma lipids versus simvastatin or fenofibrate monotherapies. Subjects with mixed dyslipidemia at high or very high cardiovascular risk on stable statin therapy for at least 3 months were included in a randomized, double-blind, active-control, parallel-group study. Patients were treated with FDC fenofibrate/simvastatin 145/20 mg or 145/40 mg, simvastatin 20 mg or 40 mg, or fenofibrate 145 mg for 12 weeks. Plasma lipids, C-reactive protein, and cystatin C were measured before and after treatments. Differences in % changes were compared between FDC fenofibrate/simvastatin and monotherapies. Significant differences between FDC fenofibrate/simvastatin and simvastatin monotherapies were observed for the % change of TG (LS mean difference [two-sided 95% CI]: -32.2% [-38.6%, -25.8%], P < 0.001) and HDL-C (7.5% [4.7%, 10.2%], P < 0.001). A significant difference between the FDC fenofibrate/simvastatin and fenofibrate was observed for LDLC % changes (-34.7% [-40.8%, -28.5%], P < 0.001). Significant differences between FDC fenofibrate/simvastatin and their respective monotherapies were also observed for Apo B and non-HDLC % changes. The FDC were well tolerated with a similar safety profile compared with monotherapies. FDC fenofibrate/simvastatin are effective and well-tolerated therapies to improve the TG and HDLC profile in high-risk patients with mixed dyslipidemia. © 2015 John Wiley & Sons Ltd.

Remnants are partially hydrolyzed, triglyceride-rich lipoproteins that are implicated in atherosclerosis. We assessed the adequacy of pitavastatin 4 mg and pravastatin 40 mg in reducing atherogenic lipid parameters beyond LDL-C, in particular remnant lipoprotein cholesterol (RLP-C). From the Phase IV, multicenter, randomized, double-blind PREVAIL US (A Study of Pitavastatin 4 mg Vs. Pravastatin 40 mg in Patients With Primary Hyperlipidemia or Mixed Dyslipidemia) trial, we examined lipoprotein cholesterol subfractions using Vertical Auto Profile testing and apolipoproteins B and A-I at baseline and 12 weeks. Participants with primary hyperlipidemia or mixed dyslipidemia had LDL-C levels of 130 to 220 mg/dL and triglyceride levels ≤ 400 mg/dL. In this post hoc analysis, changes in lipid parameters were compared by using ANCOVA. Lipoprotein subfraction data were available in 312 patients (pitavastatin, n = 157; pravastatin, n = 155). Pitavastatin promoted a greater reduction in RLP-C than pravastatin (-13.6 [8.7] vs -9.3 [9.5] mg/dL). Furthermore, the pitavastatin group reported greater reductions in both components of RLP-C (both, P < 0.001): intermediate-density lipoprotein cholesterol (-9.5 [6.3] vs -6.4 [6.6] mg/dL) and very low-density lipoprotein cholesterol subfraction 3 (-4.1 [3.5] vs -2.9 [3.8] mg/dL). There were also greater reductions in the major ratios of risk (apolipoprotein B/apolipoprotein A-I and total cholesterol/HDL-C) (both, P < 0.001). There were no significant changes in HDL-C, its subfractions, or natural log lipoprotein(a)-cholesterol. The mean age was 58.8 ± 8.9 years in the pitavastatin group and 57.0 ± 10.2 years in the pravastatin group. Compared with pravastatin 40 mg daily, pitavastatin 4 mg provided superior reductions in atherogenic lipid parameters beyond LDL-C, including RLP-C. Future studies are needed investigate the clinical implications of lowering directly measured RLP-C as the principal target. ClinicalTrials.gov identifier

The guidelines of the American College of Cardiology/American Heart Association and the British National Institute for Health and Clinical Excellence on the management and treatment of dyslipidemia recommend significant changes, such as the abolition of therapeutic targets and the use of new risk tables. This study aimed to evaluate the impact of the use of these new guidelines compared with the application of European guidelines. Observational study conducted among Spanish workers. We included all workers registered with the Sociedad de Prevención de Ibermutuamur in 2011 whose cardiovascular risk could be evaluated. Cardiovascular risk was calculated for each worker using the Systematic Coronary Risk Evaluation cardiovascular risk tables for low-risk countries, as well as the tables recommended by the American and British guidelines. A total of 258,676 workers were included (68.2% men; mean age, 39.3 years). High risk was found in 3.74% of the population according to the Systematic Coronary Risk Evaluation tables and in 6.85% and 20.83% according to the British and American tables, respectively. Treatment would be needed in 20 558 workers according to the American guidelines and in 13,222 according to the British guidelines, but in only 2612 according to the European guidelines. By following the American guidelines, the cost of statins would increase by a factor of 8. The new recommendations would result in identifying more high-risk patients and in treating a larger fraction of the population with lipid-lowering drugs than with the European recommendations, which would result in increased costs.

While heart rate reduction (HRR) is a target for the management of patients with heart disease, contradictory results were reported using ivabradine, which selectively inhibits the pacemaker I f current, vs. β-blockers like metoprolol. This study aimed at testing whether similar HRR with ivabradine vs. metoprolol differentially modulates cardiac energy substrate metabolism, a factor determinant for cardiac function, in a mouse model of dyslipidemia (hApoB +/+ ;LDLR -/- ). Following a longitudinal study design, we used 3- and 6-mo-old mice, untreated or treated for 3 mo with ivabradine or metoprolol. Cardiac function was evaluated in vivo and ex vivo in working hearts perfused with 13 C-labeled substrates to assess substrate fluxes through energy metabolic pathways. Compared with 3-mo-old, 6-mo-old dyslipidemic mice had similar cardiac hemodynamics in vivo but impaired (P < 0.001) contractile function (aortic flow: -45%; cardiac output: -34%; stroke volume: -35%) and glycolysis (-24%) ex vivo. Despite inducing a similar 10% HRR, ivabradine-treated hearts displayed significantly higher stroke volume values and glycolysis vs. their metoprolol-treated counterparts ex vivo, values for the ivabradine group being often not significantly different from 3-mo-old mice. Further analyses highlighted additional significant cardiac alterations with disease progression, namely in the total tissue level of proteins modified by O-linked N-acetylglucosamine (O-GlcNAc), whose formation is governed by glucose metabolism via the hexosamine biosynthetic pathway, which showed a similar pattern with ivabradine vs. metoprolol treatment. Collectively, our results emphasize the implication of alterations in cardiac glucose metabolism and signaling linked to disease progression in our mouse model. Despite similar HRR, ivabradine, but not metoprolol, preserved cardiac function and glucose metabolism during disease progression. Copyright © 2016 the American Physiological Society.

Gut microbiome dysbiosis plays a profound role in the pathogenesis of obesity and tributyltin (TBT) has been found as an environmental obesogen. However, whether TBT could disturb gut microbiome and the relationship between obesity induced by TBT exposure and alteration in gut microbiota are still unknown. In order to assess the association between them, mice were exposed to TBTCl (50 μg kg -1 ) once every three days from postnatal days (PNDs) 24 to 54. The results demonstrated that TBT exposure resulted in increased body weight gain, lager visceral fat accumulation and dyslipidemia in male mice on PND 84. Correspondingly, 16S rRNA gene sequencing revealed that TBT treatment decreased gut microbial species and perturbed the microbiome composition in mice. Furthermore, Pearson's corelation coefficient analysis showed a significantly negative correlation between the body weight and the alpha diversity of gut microbiome. These results suggested that TBT exposure could induce gut microbiome dysbiosis in mice, which might contribute to the obesity pathogenesis. Copyright © 2018 Elsevier B.V. All rights reserved.

Therapeutic Potential of Moringa oleifera Leaves in Chronic Hyperglycemia and Dyslipidemia: A Review

Moringa oleifera (M. oleifera) is an angiosperm plant, native of the Indian subcontinent, where its various parts have been utilized throughout history as food and medicine. It is now cultivated in all tropical and sub-tropical regions of the world. The nutritional, prophylactic, and therapeutic virtues of this plant are being extolled on the Internet. Dietary consumption of its part is therein promoted as a strategy of personal health preservation and self-medication in various diseases. The enthusiasm for the health benefits of M. oleifera is in dire contrast with the scarcity of strong experimental and clinical evidence supporting them. Fortunately, the chasm is slowly being filled. In this article, I review current scientific data on the corrective potential of M. oleifera leaves in chronic hyperglycemia and dyslipidemia, as symptoms of diabetes and cardiovascular disease (CVD) risk. Reported studies in experimental animals and humans, although limited in number and variable in design, seem concordant in their support for this potential. However, before M. oleifera leaf formulations can be recommended as medication in the prevention or treatment of diabetes and CVD, it is necessary that the scientific basis of their efficacy, the therapeutic modalities of their administration and their possible side effects be more rigorously determined.

Cardiovascular diseases are the most common cause of death in the world, atherosclerosis being its main underlying disease. Information about the role of B cells during atherosclerotic process is scarce, but both proatherogenic and atheroprotective properties have been described in the immunopathology of this disease. Frequency and phenotype of B cell subpopulations were studied in wild type and apolipoprotein-E-deficient (apoE−/−) mice fed or not with high-fat diet (HFD), by flow cytometry. Here, we provide the information about the materials, methods, analysis and additional information related to our study published in Atherosclerosis (DOI: 10.1016/j.atherosclerosis.2015.12.022, article reference: ATH14410) [1]. The data contained in this article shows and supports that mice with advanced atherosclerosis have a variety of alterations in frequency and phenotype of B cell subsets, most of which associated with dyslipidemia.

The purpose of this study was to compare the physical activity and caloric intake trends of lipid-lowering drug users with those of non-users among Korean adults with dyslipidemia. This study was a repeated cross-sectional study with a nationally representative sample of 2,635 Korean adults with dyslipidemia based on the 2010-2013 Korea National Health and Nutrition Examination Survey. Physical activity was assessed using the International Physical Activity Questionnaire, and caloric intake was estimated through 24-hour dietary recall. All statistical analyses were conducted using IBM SPSS ver. 21.0 (IBM Co., Armonk, NY, USA). The changes in physical activity and caloric intake were investigated for lipid-lowering drug users and non-users using generalized linear models. The proportion of lipid-lowering drug users in the 2010-2013 survey population increased from 3.5% to 5.0% (P<0.001). Among adults of dyslipidemia, total of 1,562 participants (56.6%) reported taking lipid-lowering drugs, and 1,073 (43.4%) reported not taking lipid-lowering drugs. Drug users were more likely to be older and less educated and to have a diagnosis of diabetes, higher body mass index, and lower low density lipoprotein cholesterol level. Physical activity trends were tested separately for the lipid-lowering drug users and non-users, and a significant decrease was found among the drug users during the study period. Physical activity among the drug users in 2013 was 38% lower (1,357.3±382.7 metabolic equivalent [MET]; P for trend=0.002) than in 2010 (2,201.4±442.6 MET). In contrast, there was no statistically significant difference between drug users and non-users in the trend of caloric intake during the same period. Physical activity significantly decreased among lipid-lowering drug users between 2010 and 2013, which was not observed among non-users. The importance of physical activity may need to be re-emphasized for lipid-lowering drug users.

The process of atherosclerosis begins at early ages and is closely related to plasma lipid levels, specifically, an increase in low density lipoprotein (LDL), very low density lipoprotein (VLDL), and a decrease in high density lipoprotein (HDL). To determine if high birth weight, or macrosomia, is of predictive value for dyslipidemia in school children. A descriptive study with a case control design was conducted on two groups of children; one group of 140 children with a history of macrosomia, and another group of 100 children with normal weight at birth, born between January 1992 and December 1995. The aim was the early identification of atherosclerotic risk factors in school children with high weight at birth. Anthropometric variables and lipid profile were studied (cholesterol, HDL-cholesterol, LDL-cholesterol, VLDL-cholesterol, and triglycerides). There were significant differences between the mean weights of the two groups. There were no significant statistical differences between the two groups in the cholesterol levels (93.57% normal and 6.43% abnormal in the study group, and 90.00% normal and 10.00% abnormal in the control group), or in the values of HDL cholesterol. LDL cholesterol was abnormal in more children in the control group, and abnormal values of triglycerides were observed in 14.00% of cases in the study group 0.00% in the control group. High birth weight is not a predictive factor for hypercholesterolemia or HDL and LDL-cholesterol esters, but is positive for triglycerides in our study.

The aim of the study was to explore the effects of n-3 polyunsaturated fatty acids (PUFA) supplementation in physiological doses on oxidative stress (OS) and dyslipidemia in patients on hemodialysis (HD). Randomized, double-blind, controlled, experimental trial. A total of 88 HD patients ≥18 years old and on HD for at least 6 months. A total of 43 patients received 1.28 g/day of n-3 PUFA, and 45 other patients received soybean oil for 12 weeks. Both oil supplements were vitamin E standardized. Routine tests, lipid profile, advanced oxidation protein products, isoprostanes, vitamins C and E, total antioxidant capacity, serum fatty acids, and adverse effects were evaluated. Supplementation was not able to alter lipid or OS profiles. There was an increase in the serum n-3 PUFA levels (eicosapentaenoic acid: +116%; docosahexaenoic acid: +100%) and an improvement in the n-6/n-3 ratio (-49%) in the supplemented group. Associations between n-3 PUFA and improvement in isoprostane and advanced oxidation protein product and HDL were observed. Treatment was well tolerated. Although the n-3 PUFA supplementation was associated with lower concentrations of isoprostane and advanced oxidation protein product and higher HDL levels, it was not sufficient for the improvement of highly prevalent risk factors, such as OS and dyslipidemia in HD patients.

The pill burden of patients with hypertension and dyslipidemia can result in poor medication compliance. This study aimed to evaluate the efficacy and safety of fixed-dose combination (FDC) therapy with olmesartan medoxomil (40 mg) and rosuvastatin (20 mg) in Korean patients with mild to moderate hypertension and dyslipidemia. This multicenter, randomized, double-blind, factorial-design study included patients aged ≥20 years with mild to moderate essential hypertension and dyslipidemia. Patients were randomly assigned to receive FDC therapy (40 mg olmesartan medoxomil, 20 mg rosuvastatin), 40 mg olmesartan medoxomil, 20 mg rosuvastatin, or a placebo. The percentage change from baseline in low-density lipoprotein cholesterol levels was compared between FDC therapy and olmesartan medoxomil, and the change from baseline in diastolic blood pressure was compared between FDC therapy and rosuvastatin 8 weeks after treatment. A total of 162 patients were included. The least square mean percentage change (standard error) from baseline in low-density lipoprotein cholesterol levels 8 weeks after treatment was significantly greater in the FDC than in the olmesartan medoxomil group (−52.3% [2.8%] vs −0.6% [3.5%], P<0.0001), and the difference was −51.7% (4.1%) (95% confidence interval: −59.8% to −43.6%). The least square mean change (standard error) from baseline in diastolic blood pressure 8 weeks after treatment was significantly greater in the FDC group than in the rosuvastatin group (−10.4 [1.2] mmHg vs 0.1 [1.6] mmHg, P<0.0001), and the difference was −10.5 (1.8) mmHg (95% confidence interval: −14.1 to −6.9 mmHg). There were 50 adverse events in 41 patients (22.7%) and eight adverse drug reactions in five patients (2.8%). The study found that FDC therapy with olmesartan medoxomil and rosuvastatin is an effective, safe treatment for patients with hypertension and dyslipidemia.

Obesity is currently considered a serious public health issue due to its strong impact on health, economy, and quality of life. It is considered a chronic low-grade inflammation state and is directly involved in the genesis of metabolic disturbances, such as insulin resistance and dyslipidemia, which are well-known risk factors for cardiovascular disease. Furthermore, there is evidence that genetic variation that predisposes to inflammation and metabolic disturbances could interact with environmental factors, such as diet, modulating individual susceptibility to developing these conditions. This paper aims to review the possible interactions between diet and single-nucleotide polymorphisms (SNPs) in genes implicated on the inflammatory response, lipoprotein metabolism, and oxidative status. Therefore, the impact of genetic variants of the peroxisome proliferator-activated receptor-(PPAR-)gamma, tumor necrosis factor-(TNF-)alpha, interleukin (IL)-1, IL-6, apolipoprotein (Apo) A1, Apo A2, Apo A5, Apo E, glutathione peroxidases 1, 2, and 4, and selenoprotein P exposed to variations on diet composition is described.

We explored the effects of atorvastatin on BMD and biochemical markers of bone metabolism in a 1-year, prospective, randomized controlled study. 64 male patients with osteopenia and mild dyslipidemia (mean age 80.1±6.6 years) were randomized to a 1-year atorvastatin treatment or control. BMD of hip and lumbar spine was measured with dual-energy X-ray absorptionmetry (DXA). Bone metabolic markers including resorption markers β-c-terminal telopeptide of type I collagen (CTx), formative markers osteocalcin (OC), 25-hydroxyvitamin D (25(OH)D) were measured with electrochemiluminescence immunoassay (ECLIA). Other bone metabolism markers including intact parathyroid hormone (iPTH) and testosterone were measured with chemiluminescence enzyme immunoassay (CLEIA). Levels of serum lipid and biochemical parameters were measured with automatic biochemical analyzer. All the parameters were recorded at baseline, and at 6 and 12 months, respectively. Compared with the control group, the atorvastatin treatment group showed significant reduction of triglyceride (TG, P<0.01) and low-density lipoprotein cholesterol (LDL-C, P<0.01). At 12 month, total hip BMD in atorvastatin group was significantly higher (P<0.01) compared with the control group, while there were no similar effect on femoral neck or lumbar spine between the two groups (P=0.48 and 0.53 respectively). Meanwhile, CTx significantly reduced in atorvastatin treatment group (P<0.001) compared with baseline. Our findings suggest that in elderly male patients with osteopenia and mild dyslipidemia, therapeutic doses of atorvastatin were associated with positive effects on BMD, probably mediated by suppressed bone resorption.

Literature has confirmed the pathogenic role of cadmium (Cd) and its exposure in the induction of dyslipidemia implicated in the development and increasing incidence of cardiovascular diseases. The current study explored whether polyphenolics isolated from virgin coconut oil (VCO) prevent Cd-induced dyslipidemia and investigate the underlying mechanism of action, in rats. Rats were pretreated with VCO polyphenols (10, 20 and 50 mg/kg body weight; orally) 2 weeks prior to concurrent Cd administration (5 mg/kg) for 5 weeks. Subsequently, serum concentrations of lipid and lipoprotein cholesterol and cardiovascular risk ratios were determined. Hepatic activities of superoxide dismutase (SOD) and catalase (CAT) as well as reduced glutathione (GSH) and malondialdehyde (MDA) contents were analyzed. Sub-chronic Cd administration significantly increased the serum levels of total cholesterol, triglycerides, low density lipoprotein cholesterol and very low density lipoprotein cholesterol while markedly reduced high density lipoprotein cholesterol. Hepatic activities of SOD and CAT as well as GSH content were suppressed by Cd, whereas MDA level was obviously increased. The co-administration of VCO polyphenol with Cd remarkably restored lipid profile and cardiovascular risk ratios and stabilized antioxidant defense systems comparable to control group. This is the first study presenting that polyphenols isolated from VCO prevent Cd-induced lipid abnormalities and cardiovascular risk ratios by improving antioxidant defense systems.

In contrast to current guidelines in Western countries, moderate reduction of low-density lipoprotein cholesterol (LDL-C) is recommended for Japanese patients with atherosclerotic cardiovascular disease and dyslipidemia even in secondary prevention. HIJ-PROPER (Heart Institute of Japan-PRoper level of lipid lOwering with Pitavastatin and Ezetimibe in acute coRonary syndrome) is a prospective, randomized, open-label, blinded endpoint multicenter trial designed to assess whether closely controlled LDL-C lowering with a standard statin dose plus ezetimibe, targeting LDL-C of <70mg/dL, would reduce cardiovascular events more than standard statin monotherapy targeting LDL-C of <100mg/dL as per the Japan Atherosclerotic Society guideline in patients with acute coronary syndrome (ACS) and dyslipidemia. We recruited patients with ACS and dyslipidemia who had undergone coronary angiography. Participants are randomly allocated to either intensive LDL-C lowering treatment (target LDL-C of <70mg/dL; pitavastatin plus ezetimibe) or standard LDL-C lowering treatment (target LDL-C of 90-100mg/dL; pitavastatin monotherapy). The primary endpoint is a composite of total death, non-fatal myocardial infarction (MI), non-fatal stroke, unstable angina, and any ischemia-driven revascularization. Patients will be followed for a minimum of 3 years. Between January 2010 and April 2013, 1734 patients were enrolled from 19 hospitals in Japan with a mean age of 65.6 years; 75.5% were men and 83.3% were statin-naïve. The qualifying ACS was an acute MI in 61.5%. This study is expected to report its findings in August 2016. HIJ-PROPER will determine whether targeting LDL-C of <70mg/dL with pitavastatin plus ezetimibe can improve cardiovascular outcomes in Japanese patients with ACS and dyslipidemia in comparison to targeting LDL-C of 90-100mg/dL with standard pitavastatin monotherapy.

To evaluate the influence of the interaction between endothelial nitric oxide synthase gene (NOS3) polymorphisms at positions -786T>C, Glu298Asp and intron 4b/a, and cardiorespiratory fitness on plasma nitrite/nitrate levels, blood pressure, lipid profile, and prevalence of cardiometabolic disorders. Ninety-two volunteers were genotyped for NOS3 polymorphisms at positions (-786T>C and Glu298Asp) and (intron 4b/a) and divided according to the genotype: non-polymorphic (NP) and polymorphic (P). After that, they were subdivided according to the cardiorespiratory fitness associated with genotype: high (HNP and HP) and low (LNP and LP). The subjects with polymorphism for the interactions at positions Glu298Asp + intron 4b/a, and Glu298Asp+-786T>C showed the highest values in total cholesterol, as well as dyslipidemia. Our findings show that NOS3 gene polymorphisms at positions -786T>C, Glu298Asp, and intron 4b/a exert negative effects on the lipid profile compared with those who do not carry polymorphisms.

Evening administration of the conventional immediate-release (IR) formulation of simvastatin is recommended because of its short half-life (1.9 hours). In a healthy population, morning administration of a controlled-release (CR) formulation of simvastatin was shown to have equivalent lipid-lowering efficacy and a safety profile similar to that of evening doses of IR simvastatin. The present study aimed to verify noninferiority and to compare the safety of morning administration of CR simvastatin with that of evening administration of IR simvastatin in patients with chronic kidney disease (CKD) who have dyslipidemia. The present study was a prospective, multicenter, double-blind, Phase IV trial with an active comparator. We randomly assigned 122 patients with CKD and dyslipidemia to 1 of 2 drug administration groups: morning administration of CR simvastatin 20 mg (test group) and evening administration of IR simvastatin 20 mg (control group). After 8 weeks, the treatment outcomes and adverse effects of the 2 treatments were compared. The mean (SD) percentage of change in serum LDL-C at the end of treatment was -35.1% (15.7%) for the test group and -35.6% (14.6%) for the control group. The difference between the 2 groups was not significant (P = 0.858). The 95% CI of the difference in the percentage of change of LDL-C between the test and control groups was -6.0 to 5.0. There was no difference in the percentage of change of total cholesterol (-24.3% [12.5%] vs -26.5% [12.0%], P = 0.317), triglyceride (-10.6% [35.1%] vs -12.4% [33.2%], P = 0.575) and HDL-C (10.2% [20.7%] vs 4.5% [11.4%], P = 0.064). Treatment-related adverse events were similar in both groups (10 events in the test group vs 8 events in the control group, P = 0.691). The efficacy of morning administration of CR simvastatin was noninferior to evening administration of IR simvastatin in patients with CKD. Furthermore, the safety profile analysis showed no significant difference between the 2 treatments

Morus nigra has been used popularly for several proposes, including diabetic. In an attempt to support medicinal value, the acute hypoglycemic, hypolipidemic, and antioxidant effects of the ethanolic extract of Morus nigra (EEMn 200 or 400 mg/kg b.w.) were evaluated in normal and alloxan-induced diabetic treated for 14 days. Serum biochemical and antioxidant analysis were performed at the end of experiment. Oral glucose tolerance test was performed at 10th and 15th days. Chromatographic analysis by HPLC-DAD of EEMn was performed. Insulin was used as positive control to glycemic metabolism as well as fenofibrate to lipid metabolism. EEMn (400 mg/kg/day) reduced fasting and postprandial glycaemia, improved oral glucose tolerance, and reduced lipolysis and proteolysis in diabetic rats. EEMn decreased the blood levels of total cholesterol and increased HDL level when compared to the diabetic control rats. At higher levels, EEMn reduced triglycerides and VLDL levels in diabetic rats. Also, EEMn reduced malondialdehyde and increased the reduced glutathione levels in liver of diabetic rats. Chromatographic analysis identified the presence of the flavonoids rutin, isoquercetin, and kaempferitrin. Acute EEMn treatment reduced hyperglycemia, improved oral glucose tolerance, and minimized dyslipidemia and oxidative stress leading to a reduction in atherogenic index in alloxan-induced diabetic rats.

Computational models of complex systems, such as signaling networks and biological systems, can be used to explain the behavior of such systems under various conditions. The large number of integrated processes and variables, and the nonlinearities inherent in the fundamental processes, make it difficult for scientists unassisted by computer simulations to effectively predict the consequences of a particular intervention. For this reason, computer simulation has become an important tool for generating hypotheses about the behavior of these systems that can then be tested in the laboratory and clinic. A dynamic data-driven application simulation (DDDAS) was designed by Biospherics to model complex metabolic disease pathways by testing potential binary therapies in simulations at various combinations of two points in the pathways. Since DDDAS chooses the most effective pair-wise combinations, this data-driven system allows for the implementation of real-time data to model or predict a measurement or event. By incorporating data dynamically rather than statically, the predictions and measurements become more reliable. Dyslipidemia, a common precursor to atherosclerosis, can be manifested by high triglycerides, increased apolipoprotein (Apo) B, high levels of LDL, and low levels of HDL. SPX106 and D-tagatose is a combination drug therapy composed of a carbohydrate (D-tagatose) and SPX106. D-tagatose has been studied for the treatment of diabetes for several years, and has the ability to lower blood insulin levels and to decrease glycogen formation. SPX106 is a natural substance that accelerates lipid catabolism and inhibits dyslipidemia. In apolipoprotein E knockout mice (ApoE−/−), this drug combination has been shown to significantly lower both the amount of atherosclerosis and blood cholesterol levels. This study used 26 male ApoE−/− mice (n=13 in each group, control and treated). The control group received the normal “Western” diet (Harlan TD88137) and

Lymphocytes, the cellular effectors of adaptive immunity, are involved in the chronic inflammatory process known as atherosclerosis. Proatherogenic and atheroprotective properties have been ascribed to B cells. However, information regarding the role of B cells during atherosclerosis is scarce. Both the frequency and the phenotype of B cell subpopulations were studied by flow cytometry in wild type and apolipoprotein-E-deficient (apoE(-/-)) mice fed a high-fat (HFD) or control diet. Whereas the proportion of follicular cells was decreased, transitional 1-like cells were increased in mice with advanced atherosclerotic lesions (apoE(-/-) HFD). B cells in atherosclerotic mice were more activated, indicated by their higher surface expression of CD80, CD86, CD40 and CD95 and increased serum IgG1 levels. In the aorta, a decreased frequency of B cells was observed in mice with advanced atherosclerosis. Low expression of CD19 was observed on B cells from the spleen, aorta and lymph nodes of apoE(-/-) HFD mice. This alteration correlated with serum levels of IgG1 and cholesterol. A reduction in CD19 expression was induced in splenic cells from young apoE(-/-) mice cultured with lipemic serum. These results show that mice with advanced atherosclerosis display a variety of alterations in the frequency and phenotype of B lymphocytes, most of which are associated with dyslipidemia.

To investigate the mechanism implicated in the effect of an insoluble fiber (obtained from carob pod) rich in polyphenols (IFCP) in lipid metabolism in the liver. Male New Zealand rabbits were fed with the following diets for 8 weeks: control diet (CT group), dyslipidemic diet supplemented with 0.5% cholesterol + 14% coconut oil (DL group) and dyslipidemic diet containing 0.5% cholesterol + 14% coconut oil plus 3% IFCP (DL + IFCP group). Dyslipidemic diet with IFCP was able to reduce development of mixed dyslipidemia, liver relative weight and collagen I protein expression compared to DL rabbits. Analyses of the main enzymes implicated in cholesterol and triglycerides metabolism revealed that IFCP increased hepatic concentration of 3-hydroxy-3-methylglutaryl-CoA reductase (HMG-CoA reductase) and cytochrome P450, family 7, subfamily a, polypeptide 1C (CYP7A1) (82.34, 114.42%, respectively) as well as protein expression of LDL receptor (42.48%) in DL rabbits. Importantly, IFCP also increased hepatic lipase (HL) levels (91.43%) and decreased glycerol phosphate acyltransferase (GPAT) and sterol regulatory element-binding protein 1C (SREBP1c) liver expression levels (20.38 and 41.20%, respectively). Finally, sirtuin 1 (SIRT1) and peroxisome proliferator-activated receptor gamma coactivator-1alpha (PGC-1α) hepatic expression increased in DL + IFCP group compared with DL (159.81 and 48.00%, respectively). These findings show that IFCP is able to abrogate the deleterious effects of hepatic dyslipidemia by modulating SIRT1 and PGC-1α pathways.

Obesity is considered to be a low-grade chronic inflammatory process, which is associated with cardiovascular and metabolic diseases. An integral evaluation of the effects of ferulic acid on biomarkers of glucose dysregulation, dyslipidemia, inflammation, and antioxidant potential induced by a high-fat diet (HFD) in rats was carried out. Three groups of male Wistar rats (six per group) consumed a basal diet (BD), which was supplemented with either lard at 310 g/kg (HFD) or lard and ferulic acid at 2 g/kg (HFD + FA), ad libitum for eight weeks. Body weight gain, hyperplasia, and hypertrophy in abdominal fat tissues were higher in the HFD group than in the HFD+FA group. The rats fed a HFD + FA significantly inhibited the increase in plasma lipids and glucose, compared with the HFD group. Biomarkers associated with inflammation were found at higher concentrations in the serum of rats fed a HFD than the HFD + FA group. Plasma antioxidant levels were lower in HFD rats compared to rats fed the HFD + FA. These results suggest that ferulic acid improves the obesogenic status induced by HFD, and we elucidated the integral effects of ferulic acid on a biological system. PMID:28661434

Cardiovascular disease (CVD) is the leading cause of morbidity and mortality in the United States. Recently published cholesterol treatment guidelines emphasize the use of statins as the preferred treatment strategy for both primary and secondary prevention of CVD. However, the optimal treatment strategy for patients who cannot tolerate statin therapy or those who need additional lipid-lowering therapy is unclear in light of recent evidence that demonstrates a lack of improved cardiovascular outcomes with combination therapy. The purpose of this review is to summarize and interpret evidence that evaluates nonstatin drug classes in reducing cardiovascular outcomes, to provide recommendations for use of nonstatin therapies in clinical practice, and to review emerging nonstatin therapies for management of dyslipidemia. Relevant articles were identified through searches of PubMed, International Pharmaceutical Abstracts, and the Cochrane Database of Systematic Reviews by using the terms niacin, omega-3 fatty acids (FAs), clofibrate, fibrate, fenofibrate, fenofibric acid, gemfibrozil, cholestyramine, colestipol, colesevelam, ezetimibe, proprotein convertase subtilisin/kexin 9 (PCSK9), cholesteryl ester transfer protein (CETP), and cardiovascular outcomes. Only English language, human clinical trials, meta-analyses, and systematic reviews were included. Additional references were identified from citations of published articles. Niacin may reduce cardiovascular events as monotherapy; however, recent trials in combination with statins have failed to show a benefit. Trials with omega-3 FAs have failed to demonstrate significant reductions in cardiovascular outcomes. Fibrates may improve cardiovascular outcomes as monotherapy; however, trials in combination with statins have failed to show a benefit, except in those with elevated triglycerides (>200 mg/dL) or low HDL-C (<40 mg/dL). There is a lack of data that evaluates bile acid sequestrant in combination with statin therapy

A well-balanced diet is the first-line treatment in hyperlipidemia. The objective was to study the association between serum phytosterols and dietary patterns to use them as surrogate markers of dietary compliance in primary dyslipidemias. 288 patients with primary hyperlipidemias (192 autosomal dominant hypercholesterolemia (ADH) and 96 familial combined hyperlipidemia (FCHL)) were included. Principal factor analysis identified 2 major dietary patterns using a 137-item food frequency questionnaire. "Vegetable & Fruits pattern" was characterized by higher intake of fruits, green beans, nuts, tomatoes, roasted or boiled potatoes, lettuce and chard and lower of processed baked goods, pizza and beer. "Western pattern" was positively characterized by hamburgers, pasta, sunflower oil, rice, chickpeas, whole milk, veal, red beans and negatively with white fish. Serum non-cholesterol sterols were determined by HPLC-MS/MS. Plant sterols to-total cholesterol (TC) levels were lower with a higher adherence to a "Vegetable & Fruits pattern" (P = 0.009), mainly in ADH subjects (R(2) = 0.019). Their concentration was greater with higher compliance to "Western pattern" especially in FCHL (P = 0.014). Higher levels of synthesis markers-to-TC with a greater adherence to "Vegetable & Fruits pattern" were found (P = 0.001) (R(2) = 0.033 and R(2) = 0.109 in ADH and FCHL respectively). In subjects with primary dislipidemia, dietary patterns associate with serum absorption and synthesis markers, but no with lipid concentrations. The influence of diet on non-cholesterol sterols levels is not powerful enough to use them as subrogate markers.

Objective The objective of this study was to assess the mean intima-media thickening of carotid arteries of elderly subjects, and its relationship with age, anthropometric measurements, high systolic blood pressure and dyslipidemia. Methods In this investigation, 129 subjects were enrolled between 1995 and 1998, age ranging from 29 to 94 years. They were assigned to one of 4 groups, including 2 control groups (group I, of healthy younger subjects; group II of healthy elderly subjects). Groups III and IV included those who presented with isolated systolic hypertension (ISH), and ISH and dyslipidemia, respectively. All subjects were submitted to a medical interview, lab tests with measurement of cholesterol levels, electrocardiogram, and carotid ultrasound. The ultrasound included measurement of the intima-media thickening (IMT) of the carotid arteries, the right carotid artery (RCA) and left carotid artery (LCA), and assessment of the presence of plaques. Blood fat and glucose were measured by a standard method. The results were compared among the groups through statistical tests. The tests employed were: Chi-Square, Pearson’s and Likelihood Ratio, Student’s t, Mann-Whitney; ANOVA followed by Tukey’s test, Kruskal-Wallis nonparametric test, and test for multiple comparisons and Odds Ratio determination (OR). Results In this investigation, a positive association was observed between aging and IMT. In relation to systolic hypertension, a significant association was observed with IMT (IMT-RCA p = 0.0034; IMT-LCA p = 0.0196; IMT-RLCA p = 0.0299), and with the presence of plaques (PlaqueR p = 0.0110; PlaqueL p = 0.0294; PlaqueRL p = 0.0040). Conclusion This investigation evidenced the important role of aging in IMT, and of systolic hypertension in the IMT and presence of plaque. However, further studies are needed for a better understanding of the actual role of risk factors in aging. PMID:18982922

We did not find any paper that assessed clinical inertia in obese patients. Therefore, no paper has compared the clinical inertia rates between morbidly and nonmorbidly obese patients. A cross-sectional observational study was carried out. We analysed 8687 obese patients ⩾40 years of age who attended their health-care center for a checkup as part of a preventive program. The outcome was morbid obesity. Secondary variables were as follows: failure in the management of high blood pressure (HBP), high blood cholesterol (HBC) and high fasting blood glucose (HFBG); gender; personal history of hypertension, dyslipidemia, diabetes, smoking and cardiovascular disease; and age (years). We analysed the association between failures and morbid obesity by calculating the adjusted odds ratio (OR). Of 8687 obese patients, 421 had morbid obesity (4.8%, 95% confidence interval (CI): 4.4-5.3%). The prevalence rates for failures were as follows: HBP, 34.7%; HBC, 35.2%; and HFBG, 12.4%. Associated factors with morbid obesity related with failures were as follows: failure in the management of HBP (OR=1.42, 95% CI: 1.15-1.74, P=0.001); failure in the management of HBC (OR=0.73, 95% CI: 0.58-0.91, P=0.004); and failure in the management of HFBG (OR=2.24, 95% CI: 1.66-3.03, P<0.001). Morbidly obese patients faced worse management for HBP and HFBG, and better management for HBC. It would be interesting to integrate alarm systems to avoid this problem.

Background Dyslipidemia and lipotoxicity-induced insulin resistance, inflammation and oxidative stress are the key pathogeneses of renal damage in type 2 diabetes. Increasing evidence shows that whole-body low dose radiation (LDR) plays a critical role in attenuating insulin resistance, inflammation and oxidative stress. Objective The aims of the present study were to investigate whether LDR can prevent type 2 diabetes-induced renal damage and the underlying mechanisms. Methods Mice were fed with a high-fat diet (HFD, 40% of calories from fat) for 12 weeks to induce obesity followed by a single intraperitoneal injection of streptozotocin (STZ, 50 mg/kg) to develop a type 2 diabetic mouse model. The mice were exposed to LDR at different doses (25, 50 and 75 mGy) for 4 or 8 weeks along with HFD treatment. At each time-point, the kidney weight, renal function, blood glucose level and insulin resistance were examined. The pathological changes, renal lipid profiles, inflammation, oxidative stress and fibrosis were also measured. Results HFD/STZ-induced type 2 diabetic mice exhibited severe pathological changes in the kidney and renal dysfunction. Exposure of the mice to LDR for 4 weeks, especially at 50 and 75 mGy, significantly improved lipid profiles, insulin sensitivity and protein kinase B activation, meanwhile, attenuated inflammation and oxidative stress in the diabetic kidney. The LDR-induced anti-oxidative effect was associated with up-regulation of renal nuclear factor E2-related factor-2 (Nrf-2) expression and function. However, the above beneficial effects were weakened once LDR treatment was extended to 8 weeks. Conclusion These results suggest that LDR exposure significantly prevented type 2 diabetes-induced kidney injury characterized by renal dysfunction and pathological changes. The protective mechanisms of LDR are complicated but may be mainly attributed to the attenuation of dyslipidemia and the subsequent lipotoxicity-induced insulin resistance

Background We assessed whether 234 established dyslipidemia-associated loci modify the effects of metformin treatment and lifestyle intervention (vs. placebo control) on lipid and lipid sub-fraction levels in the Diabetes Prevention Program (DPP) randomized controlled trial. Methods and Results We tested gene-treatment interactions in relation to baseline adjusted follow-up blood lipid concentrations (high and low density lipoprotein cholesterol [HDL-C, LDL-C], total cholesterol, triglycerides) and lipoprotein sub-fraction particle concentrations and size in 2,993 participants with pre-diabetes. Of the previously reported SNP associations, 32.5% replicated at P<0.05 with baseline lipid traits. Trait-specific genetic risk scores (GRS) were robustly associated (3×10−4>P>1.1×10−16) with their respective baseline traits for all but two traits. Lifestyle modified the effect of the GRS for large HDL particle numbers, such that each risk allele of the GRSHDL-large was associated with lower concentrations of large HDL particles at follow-up in the lifestyle arm (β=−0.11 μmol/l per GRS risk allele; 95%CI −0.188, −0.033; P=5×10−3; Pinteraction=1×10−3 for lifestyle vs. placebo), but not in the metformin or placebo arms (P>0.05). In the lifestyle arm, participants with high genetic risk had more favorable or similar trait levels at 1-yr compared to participants at lower genetic risk at baseline for 17 of the 20 traits. Conclusions Improvements in large HDL particle concentrations conferred by lifestyle may be diminished by genetic factors. Lifestyle intervention, however, was successful in offsetting unfavorable genetic loading for most lipid traits. PMID:27784733

The aim of this study was to investigate the capacity of chiglitazar to improve insulin resistance and dyslipidemia in monosodium L-glutamate (MSG) obese rats and to determine whether its lipid-lowering effect is mediated through its activation of PPARα. Chiglitazar is a PPARα/γ dual agonist. The compound improved impaired insulin and glucose tolerance; decreased plasma insulin level and increased the insulin sensitivity index and decreased HOMA index. Euglycemic hyperinsulinemic clamp studies showed chiglitazar increased the glucose infusion rate in MSG obese rats. Chiglitazar inhibited alanine gluconeogenesis, lowered the hepatic glycogen level in MSG obese rats. Like rosiglitazone, chiglitazar promoted the differentiation of adipocytes and decreased the maximal diameter of adipocytes. In addition, chiglitazar decreased the fibrosis and lipid accumulation in the islets and increased the size of islets. Chiglitazar reduced plasma triglyceride, total cholesterol (TCHO), nonesterified fatty acids (NEFA) and low density lipoprotein-cholesterol levels; lowered hepatic triglyceride and TCHO contents; decreased muscular NEFA level. Unlike rosiglitazone, chiglitazar showed significant increase of mRNA expression of PPARα, CPT1, BIFEZ, ACO and CYP4A10 in the liver of MSG obese rats. These data suggest that PPARα/γ coagonist, such as chiglitazar, affect lipid homeostasis with different mechanisms from rosiglitazone, chiglitazar may have better effects on lipid homeostasis in diabetic patients than selective PPARγ agonists.

Health disparities in total joint replacement have been documented based on gender and ethnicity in multiple countries. Absent are studies exploring the meaning of the procedures among diverse women, which is necessary to fully understand the impact of the disparity. Drawing on ethnographic data from a life course exploration of disablement among Mexican American women with mobility impairments, one woman’s reasons for forgoing a joint replacement are considered. It is suggested that inequalities in disablement cannot be understood without considering the mulitple cultural conflicts and loyalties that push and pull women in multiple directions. PMID:21767094

This paper addresses non-contact monitoring of physiological signals induced by respiration and heartbeat. To detect the tiny physiological movements of the chest or other parts of the torso, a Mulitple-Input Multiple-Output (MIMO) radar is used. The spatially distributed transmitters and receivers are able to detect the chest surface movements of one or multiple persons in a room. Due to several bistatic measurements at the same time a robust detection and measuring of the breathing and heartbeat rate is possible. Using an appropriate geometrical configuration of the sensors even a localization of the person is feasible.

The use of daily phone calls was 44.7%. Most had never used a computer (78.2%), email (84%) or the Internet (84%). Many have never sent (80.6%) or received (69.9%) a text message. 70% had at some time forgotten to take their medicine. 72.8% would like to be reminded to take their medication and 67.9% had a family member who could help them with access to ICT. Despite the low use of ICT in this population, there is willingness and expectation from the patients to participate in programs that implement them.

The role of the G protein-coupled estrogen receptor (GPER/GPR30), particularly in males, in these pathologies remains unclear. We therefore sought to determine whether loss of GPER contributes to aspects of metabolic syndrome in male mice. Although 6-month-old male and female GPER knockout (KO) mice displayed increased body weight compared with wild-type littermates, only female GPER KO mice exhibited glucose intolerance at this age. Weight gain in male GPER KO mice was associated with increases in both visceral and sc fat. GPER KO mice, however, exhibited no differences in food intake or locomotor activity. One-year-old male GPER KO mice displayed an abnormal lipid profile with higher cholesterol and triglyceride levels. Fasting blood glucose levels remained normal, whereas insulin levels were elevated. Although insulin resistance was evident in GPER KO male mice from 6 months onward, glucose intolerance was pronounced only at 18 months of age. Furthermore, by 2 years of age, a proinflammatory phenotype was evident, with increases in the proinflammatory and immunomodulatory cytokines IL-1β, IL-6, IL-12, TNFα, monocyte chemotactic protein-1, interferon γ-induced protein 10, and monokine induced by interferon gamma and a concomitant decrease in the adipose-specific cytokine adiponectin. In conclusion, our study demonstrates for the first time that in male mice, GPER regulates metabolic parameters associated with obesity and diabetes. PMID:23970785

The pathways to increased cardiovascular risk in bipolar disorder include health behaviors, psychosocial stress and long-term medication exposure. However, the evidence that the association between cardiovascular risk factors and bipolar disorder remains significant after controlling for these co-factors suggests that additional important risk factors have yet to be identified. Our hypothesis is that disturbances in the sleep-wake cycle are an important and under-recognized pathway through which affective disorders lead to increased cardiovascular risk. In patients with bipolar disorder type 1 in clinical remission, we: 1) explored whether sleep disturbance predicted the endorsement of NCEP ATP-III criteria for dyslipidemia, independent of other lifestyle factors and 2) tested the association between low HDL (NCEP-ATP III) and sleep duration measured with actigraphy over an eight-day period. Median sleep duration is significantly associated with low HDL. The risk of having low HDL increases by 1.23 with every 30 minutes of reduced sleep time. Since sleep patterns in patients with bipolar disorder are variable and irregular, it is possible that other sleep characteristics, not present during the span of our study, or the variability itself may be what drives the increased cardiovascular risk. Sleep characteristics of patients with bipolar disorder in clinical remission are associated with cardiovascular risk. More specifically, sleep duration was associated with low HDL. Clinicians should pay special attention to sleep hygiene in treating individuals with bipolar disorder, even when they are in clinical remission. Copyright © 2012 Elsevier B.V. All rights reserved.

Type 2 diabetes mellitus (T2DM) is often associated with mixed dyslipidaemia, where non-high-density lipoprotein cholesterol (non-HDL-C) levels may more closely align with cardiovascular risk than low-density lipoprotein cholesterol (LDL-C). We describe the design and rationale of the ODYSSEY DM-DYSLIPIDEMIA study that assesses the efficacy and safety of alirocumab, a proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitor, versus lipid-lowering usual care in individuals with T2DM and mixed dyslipidaemia at high cardiovascular risk with non-HDL-C inadequately controlled despite maximally tolerated statin therapy. For the first time, atherogenic cholesterol-lowering with a PCSK9 inhibitor will be assessed with non-HDL-C as the primary endpoint with usual care as the comparator. DM-DYSLIPIDEMIA is a Phase 3b/4, randomised, open-label, parallel group, multinational study that planned to enrol 420 individuals. Main inclusion criteria were T2DM and mixed dyslipidaemia (non-HDL-C ≥100 mg/dl [≥2.59 mmol/l], and triglycerides ≥150 and <500 mg/dl [≥1.70 and <5.65 mmol/l]) with documented atherosclerotic cardiovascular disease or ≥1 additional cardiovascular risk factor. Participants were randomised (2:1) to alirocumab 75 mg every 2 weeks (Q2W) or lipid-lowering usual care on top of maximally tolerated statin (or no statin if intolerant). If randomised to usual care, investigators were able to add their pre-specified choice of one of the following to the patient's current statin regimen: ezetimibe, fenofibrate, omega-3 fatty acids or nicotinic acid, in accordance with local standard-of-care. Alirocumab-treated individuals with non-HDL-C ≥100 mg/dl at week 8 will undergo a blinded dose increase to 150 mg Q2W at week 12. The primary efficacy endpoint is non-HDL-C change from baseline to week 24 with alirocumab versus usual care; other lipid levels (including LDL-C), glycaemia-related measures, safety and tolerability will also be assessed

Lysosomal acid lipase deficiency (LAL-D) is still a little recognized genetic disease with significant morbidity and mortality in children and adults. This document provides guidance on when to suspect LAL-D and how to diagnose it. It is recommended to add lysosomal acid lipase deficiency to the List of differential diagnoses of sepsis, oncological diseases, storage diseases, persistent diarrhea, chronic malnutrition, and hemophagocytic lymphohistiocytosis. It should also be considered in young patients with dyslipidemia and atherosclerosis as well as diseases associated with fatty liver and/or hepatomegaly. LAL-D should be suspected in patients with hepatomegaly, hyperlipidemia and /or elevated transaminases found during routine checks or testing for other conditions, and in patients with cryptogenic cirrhosis. At present, there is the option of a specific enzyme replacement treatment. Sociedad Argentina de Pediatría.

Prevention or amelioration the prevalence of atherosclerosis has been an effective strategy in the management of cardiovascular diseases. The aim of the study was to scrutinize the effect of Clematichinenoside (AR) on dyslipidemia-induced atherosclerosis and explore its capability on expression of Peroxisome proliferator-activated receptor-α (PPAR-alpha), apolipoprotein A-I (APOA1) and A-II (APOA2), and suppression of apolipoprotein C-III (APOC3) genes and proteins. In the present study, we investigated atherosclerosis effect of AR using a combination of high-fat diet and balloon injury model in rabbits. The levels of biochemical indicators were evaluated in plasma, liver and HepG2 cells using immunoassay technology. In order to expose the underlying mechanism, we evaluated the regulation of PPAR-alpha, APOA1, APOA2 and APOC3 expressions by AR, and we further evaluated the interactions between them after transfection with shRNA (shPPAR-alpha) and, the action of PPAR-alpha in HepG2 cells. We could find that AR markedly promoted the PPAR-alpha transfer from cytoplasm to nucleus which resulted in the alteration of APOA1, APOA2 and APOC3 expressions in HepG2 cells. Moreover, AR significantly reduced total cholesterol, triglycerides and low-density lipoprotein cholesterol (LDL-C) levels, and elevated high-density lipoprotein cholesterol (HDL-C) level, which play an important role in dyslipidemia-induced atherosclerosis. In conclusion, AR ameliorated atherosclerosis via the regulation of hepatic lipid metabolism, and AR also contributed to the activation of PPAR-alpha, APOA1, APOA2 and APOC3. Therefore, AR could be a potential therapeutic agent in the treatment of atherosclerosis. Copyright © 2015 Elsevier B.V. All rights reserved.

ED is closely associated with its comorbidities (hypertension, dyslipidemia and lower urinary tract symptoms (LUTS)). Therefore, several drugs have been prescribed simultaneously with PDE5 inhibitors. If a specific medication for ED comorbidities has enhancing effects on PDE5 inhibitors, it offers alternative combination therapy in nonresponders to monotherapy with PDE5 inhibitors and allows clinicians to treat ED and its comorbidities simultaneously. To establish theoretical basis of choosing an appropriate medication for ED and concomitant disease, we examined the effects combining a PDE5 inhibitor with representative drugs for hypertension, dyslipidemia and LUTS on relaxing the corpus cavernosum of rabbits using the organ-bath technique. The effect of mirodenafil on relaxing phenylephrine-induced cavernosal contractions was significantly enhanced by the presence of 10(-4) M losartan, 10(-6) M nifedipine, 10(-6) M amlodipine, 10(-7) M doxazosin and 10(-9) M tamsulosin (P<0.05). The maximum relaxation effects were 47.2±3.8%, 57.6±2.6%, 64.0±3.7%, 76.1±5.7% and 71.7±5.4%, respectively. Enalapril and simvastatin had no enhancing effects. The relaxation induced by sodium nitroprusside alone (39.0±4.0%) was significantly enhanced in the presence of the 10(-4) M losartan (66.0±6.0%, P<0.05). Tetraethylammonium (1 mM) significantly inhibited the enhancement effects of tamsulosin and doxazosin on mirodenafil-induced relaxation (doxazosin: 76.1±5.7% vs 45.3±2.3%; tamsulosin: 71.7±5.4% vs 48.1±3.5%). On the basis of these findings, losartan seemed to induce synergistic effects through an interaction with nitric oxide. In addition, K(+) channel activation could be one of the mechanisms for the synergistic effect of combining mirodenafil with doxazosin or tamsulosin. We believe that the combination of a PDE5 inhibitor with losartan, nifedipine, amlodipine, doxazosin or tamsulosin could be a pharmacologic strategy for simultaneously treating ED and

The leadership of the National Lipid Association convened an Expert Panel to develop a consensus set of recommendations for patient-centered management of dyslipidemia in clinical medicine. An Executive Summary of those recommendations was previously published. This document provides support for the recommendations outlined in the Executive Summary. The major conclusions include (1) an elevated level of cholesterol carried by circulating apolipoprotein B-containing lipoproteins (non-high-density lipoprotein cholesterol and low-density lipoprotein cholesterol [LDL-C], termed atherogenic cholesterol) is a root cause of atherosclerosis, the key underlying process contributing to most clinical atherosclerotic cardiovascular disease (ASCVD) events; (2) reducing elevated levels of atherogenic cholesterol will lower ASCVD risk in proportion to the extent that atherogenic cholesterol is reduced. This benefit is presumed to result from atherogenic cholesterol lowering through multiple modalities, including lifestyle and drug therapies; (3) the intensity of risk-reduction therapy should generally be adjusted to the patient's absolute risk for an ASCVD event; (4) atherosclerosis is a process that often begins early in life and progresses for decades before resulting a clinical ASCVD event. Therefore, both intermediate-term and long-term or lifetime risk should be considered when assessing the potential benefits and hazards of risk-reduction therapies; (5) for patients in whom lipid-lowering drug therapy is indicated, statin treatment is the primary modality for reducing ASCVD risk; (6) nonlipid ASCVD risk factors should also be managed appropriately, particularly high blood pressure, cigarette smoking, and diabetes mellitus; and (7) the measurement and monitoring of atherogenic cholesterol levels remain an important part of a comprehensive ASCVD prevention strategy.

From Evolution to Revolution: miRNAs as Pharmacological Targets for Modulating Cholesterol Efflux and Reverse Cholesterol Transport

PubMed Central

Dávalos, Alberto; Fernández-Hernando, Carlos

2013-01-01

There has been strong evolutionary pressure to ensure that an animal cell maintain levels of cholesterol within tight limits for normal function. Imbalances in cellular cholesterol levels are a major player in the development of different pathologies associated to dietary excess. Although epidemiological studies indicate that elevated levels of high-density lipoprotein (HDL)-cholesterol reduce the risk of cardiovascular disease, recent genetic evidence and pharmacological therapies to raise HDL levels do not support their beneficial effects. Cholesterol efflux as the first and probably the most important step in reverse cholesterol transport is an important biological process relevant to HDL function. Small non-coding RNAs (microRNAs), post-transcriptional control different aspects of cellular cholesterol homeostasis including cholesterol efflux. miRNA families miR-33, miR-758, miR-10b, miR-26 and miR-106b directly modulates cholesterol efflux by targeting the ATP-binding cassette transporter A1 (ABCA1). Pre-clinical studies with anti-miR therapies to inhibit some of these miRNAs have increased cellular cholesterol efflux, reverse cholesterol transport and reduce pathologies associated to dyslipidemia. Although miRNAs as therapy have benefits from existing antisense technology, different obstacles need to be solved before we incorporate such research into clinical care. Here we focus on the clinical potential of miRNAs as therapeutic target to increase cholesterol efflux and reverse cholesterol transport as a new alternative to ameliorate cholesterol-related pathologies.

Usually both hypothyroidism and hyperthyroidism are related to the cardiovascular and cerebrovascular disease development. The relationship between subclinical hypothyroidism has been widely investigated but the findings remain controversial. The aim of the present study was to evaluate the lipid profile in patients with subclinical hypothyroidism (SHypo) in comparison to controls and to determine the association of SHypo and dyslipidemia in attempt to find importance of small dense low-density lipoprotein cholesterol (sdLDL-C) in atherosclerosis. In this study we included 100 women, aged 30 to 70 years that were divided into subgroups according to their age. According to the values of levels of thyroid hormones they were divided into euthyroid (control) group (n = 64) and (newly discovered) subclinical hypothyroidism (SHypo) group (n = 36). A high-sensitivity C-reactive protein (hs-CRP) and lipid profile, including small dense low-density lipoprotein cholesterol (sdLDL-C) were determined. Body weight and height were measured and BMI calculated. History of the current illness, medication, alcohol consumption and cigarettes smoking were noted. Changed lipid profile as well as elevated triglycerides and sdLDL-C were observed in the group with subclinical hypothyroidism compared to the control group. It is important to determine serum lipid levels, especially serum sdLDL-C levels at an early stage of subclinical hypothyroidism, since they represent atherogenic LDL particles and are better indicators for dyslipidaemia in subclinical hypothyroidism and the development of atherosclerosis with potential complications such as cardiovascular and cerebrovascular diseases.

Adipocyte dysfunction, obesity and associated metabolic disorders are of prime healthcare concern worldwide. Among available medications, natural products and inspired molecules hold 40% space in clinically prescribed medicines. In queue, this study overcomes the drawback of curcumin's low bioavailability with potent anti-adipogenic and anti-dyslipidemic activity. To evaluate the role of CDPP on adipocyte differentiation, 3T3-L1 adipocytes were used as an in-vitro model. Flow cytometry was performed for cell cycle analysis. Syrian golden hamsters were used to study pharmacokinetic profile and dyslipidemic activity exhibited by CDPP. CDPP was found to be a potent inhibitor of adipogenesis in-vitro. It blocked mitotic clonal expansion by causing cell cycle arrest. CDPP showed marked improvement in gastrointestinal stability and bioavailability in-vivo as compared to curcumin. Administration of CDPP (100mg/kg) significantly improved HFD induced dyslipidemic profile in hamsters and activated reverse cholesterol transport machinery. CDPP could be used as a potential drug candidate against adipogenesis and dyslipidemia with enhanced gastrointestinal stability and bioavailability. Copyright © 2017 Elsevier Inc.

Dyslipidemia is a major public health problem, and therefore, it is important to develop dietary strategies to diminish the prevalence of this disorder. It was recently reported that diet may play an important role in triggering insulin resistance by interacting with genetic variants at the CAPN10 gene locus in patients with metabolic syndrome. Nonetheless, it remains unknown whether genetic variants of genes involved in the development of type 2 diabetes are associated with variations in high-density lipoprotein cholesterol (HDL-C). The study used a single-center, prospective, cohort design. Here, we assessed the effect of four variants of the CAPN10 gene on HDL-C levels in response to a soy protein and soluble fiber dietary portfolio in subjects with dyslipidemia. In 31 Mexican dyslipidemic individuals, we analyzed four CAPN10 gene variants (rs5030952, rs2975762, rs3792267, and rs2975760) associated with type 2 diabetes. Subjects with the GG genotype of the rs2975762 variant of the CAPN10 gene were better responders to dietary intervention, showing increased HDL-C concentrations from the first month of treatment. HDL-C concentrations in participants with the wild type genotype increased by 17.0%, whereas the HDL-C concentration in subjects with the variant genotypes increased by only 3.22% (p = 0.03); the low-density lipoprotein cholesterol levels of GG carriers tended to decrease (-12.6%). These results indicate that Mexican dyslipidemic carriers of the rs2975762-GG genotype are better responders to this dietary intervention. Copyright AULA MEDICA EDICIONES 2014.

D-limonene is a major constituent in citrus essential oil, which is used in various foods as a flavoring agent. Recently, d-limonene has been reported to alleviate fatty liver induced by a high-fat diet. Here we determined the preventive and therapeutic effects of d-limonene on metabolic disorders in mice with high-fat diet-induced obesity. In the preventive treatment, d-limonene decreased the size of white and brown adipocytes, lowered serum triglyceride (TG) and fasting blood glucose levels, and prevented liver lipid accumulations in high-fat diet-fed C57BL/6 mice. In the therapeutic treatment, d-limonene reduced serum TG, low-density lipoprotein cholesterol (LDL-c) and fasting blood glucose levels and glucose tolerance, and increased serum high-density lipoprotein cholesterol (HDL-c) in obese mice. Using a reporter assay and gene expression analysis, we found that d-limonene activated peroxisome proliferator-activated receptor (PPAR)-α signaling, and inhibited liver X receptor (LXR)-β signaling. Our data suggest that the intake of d-limonene may benefit patients with dyslipidemia and hyperglycemia and is a potential dietary supplement for preventing and ameliorating metabolic disorders. © 2013 Elsevier B.V.

Diabetes is associated with high risk of cardiovascular (CV) events, particularly in patients with dyslipidemia and diabetic complications. We investigated the incidence of CV events with intensive or standard lipid-lowering therapy in patients with hypercholesterolemia, diabetic retinopathy, and no history of coronary artery disease (treat-to-target approach). In this multicenter, prospective, randomized, open-label, blinded end point study, eligible patients were randomly assigned (1:1) to intensive statin therapy targeting LDL cholesterol (LDL-C) <70 mg/dL ( n = 2,518) or standard statin therapy targeting LDL-C 100-120 mg/dL ( n = 2,524). Mean follow-up was 37 ± 13 months. LDL-C at 36 months was 76.5 ± 21.6 mg/dL in the intensive group and 104.1 ± 22.1 mg/dL in the standard group ( P < 0.001). The primary end point events occurred in 129 intensive group patients and 153 standard group patients (hazard ratio [HR] 0.84 [95% CI 0.67-1.07]; P = 0.15). The relationship between the LDL-C difference in the two groups and the event reduction rate was consistent with primary prevention studies in patients with diabetes. Exploratory findings showed significantly fewer cerebral events in the intensive group (HR 0.52 [95% CI 0.31-0.88]; P = 0.01). Safety did not differ significantly between the two groups. We found no significant decrease in CV events or CV-associated deaths with intensive therapy, possibly because our between-group difference of LDL-C was lower than expected (27.7 mg/dL at 36 months of treatment). The potential benefit of achieving LDL-C <70 mg/dL in a treat-to-target strategy in high-risk patients deserves further investigation. © 2018 by the American Diabetes Association.

The medicinal value of Morinda citrifolia L. (commonly known as Noni) has been explored in ancient folk remedies with a wide range of therapeutic utility, including antibacterial, antiviral, antifungal, antitumour, analgesic, hypotensive, anti-inflammatory and immune enhancing effects. The present study was designed to evaluate the effects of Noni fruit juice on serum lipid profile in high fat diet induced murine model of dyslipidemia. Hyperlipidemia was induced by feeding a cholesterol rich high fat diet for 45 days in wistar albino rats of either sex (n=8). Noni fruit juice administered at 50mg/kg/day and 100mg/kg/day, per oral, was compared with the standard drug Atorvastatin (10mg/kg/day, oral) fed for the latter 30 days. The blood samples were then sent for complete blood lipid profile, after 30 days of treatment. The data presented as mean ± SEM was analyzed using one-way ANOVA followed by Tukey's post-hoc test. The p <0.05 was considered as statistically significant. The Noni fruit juice treated group showed a significant decrease in the total cholesterol, triglycerides and very low density lipoprotein - Cholesterol at both the doses when compared to the disease control (p<0.05). However, the decrease in the TC (102.75±9.79 mg/dL) and LDL-C (47.87±7.47 mg/dL) levels observed with the noni fruit juice at the 50mg/kg dose employed, failed to show a statistical significance when compared to atorvastatin. The present study provides evidence for the hypolipidemic activity of Noni fruit juice in high fat diet induced hyperlipidemia in rats.

We evaluated the metabolic effects and tolerability of GFT505, a novel dual peroxisome proliferator-activated receptor α/δ agonist, in abdominally obese patients with either combined dyslipidemia or prediabetes. The S1 study was conducted in 94 patients with combined dyslipidemia while the S2 study was conducted in 47 patients with prediabetes. Participants were randomly assigned in a double-blind manner to GFT505 at 80 mg/day or placebo for 28 (S1) or 35 (S2) days. Primary efficacy end points were changes from baseline at week 4 in both fasting plasma triglycerides and HDL cholesterol in the S1 group and 2-h glucose upon oral glucose tolerance test in the S2 group. In comparison with placebo, GFT505 significantly reduced fasting plasma triglycerides (S1: least squares means -16.7% [95% one-sided CI -∞ to -5.3], P = 0.005; S2: -24.8% [-∞ to -10.5], P = 0.0003) and increased HDL cholesterol (S1: 7.8% [3.0 to ∞], P = 0.004; S2: 9.3% [1.7 to ∞], P = 0.009) in both studies, whereas LDL cholesterol only decreased in S2 (-11.0% [ -∞ to -3.5], P = 0.002). In S2, GFT505 did not reduce 2-h glucose (-0.52 mmol/L [-∞ to 0.61], P = 0.18) but led to a significant decrease of homeostasis model assessment of insulin resistance (-31.4% [-∞ to 12.5], P = 0.001), fasting plasma glucose (-0.37 mmol/L [-∞ to -0.10], P = 0.01) and fructosamine (-3.6% [-∞ to -0.20], P = 0.02). GFT505 also reduced γ glutamyl transferase levels in both studies (S1: -19.9% [-∞ to -12.8], P < 0.0001; S2: -15.1% [-∞ to -1.1], P = 0.004). No specific adverse safety signals were reported during the studies. GFT505 may be considered a new drug candidate for the treatment of lipid and glucose disorders associated with the metabolic syndrome.

Methylated arginine analogues: their potential role in atherosclerosis and cognition using the poloxamer-407-induced mouse model of dyslipidemia.

An experimental mouse model of dyslipidemia and atherosclerosis was utilized to study the generation of methylarginines in vivo, as well as any potential behavioral changes in mice associated with the production of excess methylarginines. Following 14 weeks of poloxamer 407 treatment, mice developed atherosclerosis and the plasma concentrations of monomethylarginine and asymmetric dimethylarginine were found to be significantly greater than corresponding concentrations in control mice. This finding may have contributed to the development of aortic atherosclerotic lesions in poloxamer-treated mice by interfering with nitric oxide availability and, hence, normal function of vascular endothelium. Poloxamer-407-treated mice also showed a significant decrease in locomotor and exploratory activity, together with signs of emotional stress and anxiety relative to controls. Passive avoidance testing to assess learning and memory provided suggestive evidence that poloxamer-treated mice could potentially be characterized as having undergone a disruption in the process of forgetting about an aversive event, specifically, a foot shock, when compared with control mice. Thus, it is also suggested that the increase in both plasma monomethylarginine and asymmetric dimethylarginine in poloxamer-407-treated mice may somehow influence learning and memory, because endothelial dysfunction caused by reduced nitric oxide availability has been hypothesized to negatively influence cognitive function.

Previous studies have shown that multiple features of atherogenic dyslipidemia are improved by replacement of dietary carbohydrate with mixed sources of protein and that these lipid and lipoprotein changes are independent of dietary saturated fat content. Because epidemiological evidence suggests that red meat intake may adversely affect cardiovascular disease risk, we tested the effects of replacing dietary carbohydrate with beef protein in the context of high- vs. low-saturated fat intake in 40 healthy men. After a 3-wk baseline diet [50% daily energy (E) as carbohydrate, 13% E as protein, 15% E as saturated fat], participants consumed for 3 wk each in a randomized crossover design two high-beef diets in which protein replaced carbohydrate (31% E as carbohydrate, 31% E as protein, with 10% E as beef protein). The high-beef diets differed in saturated fat content (8% E vs. 15% E with exchange of saturated for monounsaturated fat). Two-week washout periods were included following the baseline diet period and between the randomized diets periods. Plasma TG concentrations were reduced after the 2 lower carbohydrate dietary periods relative to after the baseline diet period and these reductions were independent of saturated fat intake. Plasma total, LDL, and non-HDL cholesterol as well as apoB concentrations were lower after the low-carbohydrate, low-saturated fat diet period than after the low-carbohydrate, high-saturated fat diet period. Given our previous observations with mixed protein diets, the present findings raise the possibility that dietary protein source may modify the effects of saturated fat on atherogenic lipoproteins.

Objective Recent studies suggested that secreted protein acidic and rich in cysteine (SPARC), a novel adipokine, is a key player in the pathology of obesity and type 2 diabetes. We aimed to determine whether concentrations of SPARC were altered in patients with gestational diabetes mellitus (GDM) compared to normal glucose tolerance (NGT) controls and to investigate the relationships between SPARC and metabolic parameters in pregnant women. Design/Methods Cross-sectional study of 120 pregnant women with GDM and 60 controls with NGT, in a university hospital setting. Plasma levels of SPARC, adiponectin, fibroblast growth factor 21 (FGF21), insulin and proinsulin were determined by ELISA. Results GDM women had higher SPARC and lower adiponectin than NGT subjects; no difference was found in FGF21. SPARC levels were the lowest in subjects in the third tertile of insulin sensitivity index (ISIOGTT) and correlated positively with pre-pregnant BMI, insulin and 3 h glucose during 100-g OGTT, HOMA-IR, fasting proinsulin, hsCRP and white blood cells count, and negatively with ISIOGTT, when adjusting for gestational age. Triglyceride (TG), Apolipoprotein A1, apolipoprotein B and lipoprotein (a) correlated with SPARC in partial Pearson correlation. Correlations between SPARC with adiponectin, systolic blood pressure and TG were marginally significant in partial Spearman correlation analysis. In multivariate regression analysis, SPARC was an independent negative indicator of ISIOGTT. Conclusions SPARC levels are correlated significantly with inflammation and may also be correlated with dyslipidemia and represent an independent determinant of insulin resistance in late pregnancy, indicating a potential role of SPARC in the pathophysiology of GDM.

To assess the effectiveness of low-dose salmon oil for the treatment of highly active antiretroviral therapy (HAART)-induced dyslipidemia in HIV-infected patients. Randomized, open-label, parallel and crossover, multicenter study. Patients received 1 g salmon oil tid for 24 weeks (SO-24) or no additional treatment for 12 weeks and salmon oil for weeks 12 to 24 (CT-SO). The primary outcome measure was the change in triglyceride (TG) levels. Fifty-eight patients completed the study (26 in SO-24; 32 in CT-SO). After 12 weeks, the SO-24 group experienced a mean TG reduction of 1.1 mmol/L, compared to an increase of 0.3 mmol/L for the CT-SO group (p = .040). When CT-SO patients were crossed over to salmon oil treatment, mean TG decreased by 0.7 mmol/L (p = .052). Concomitant use of fibrates, statins, or both were reported by 16 (27.6%), 10 (17.2%), and 8 (13.8%), respectively. Multivariate analysis showed that salmon oil produced a significant decrease in TG levels independent of other lipid-lowering medications (p = .022). There were 26 predominately mild treatment-emergent (antiretroviral or salmon oil) nonserious adverse events reported by 22 (33.3%) patients. Low-dose salmon oil (3 g/day) is effective and well-tolerated in reducing TG levels in HIV-infected patients receiving HAART.

Targeted Inactivation of GPR26 Leads to Hyperphagia and Adiposity by Activating AMPK in the Hypothalamus

G-protein coupled receptor 26 (GPR26) is a brain-specific orphan GPCR with high expression in the brain region that controls satiety. Depletion of GPR26 has been shown to increase fat storage in C. elegans, whereas GPR26 deficiency in the hypothalamus is associated with high genetic susceptibility to the onset of obesity in mice. However, the metabolic function of GPR26 in mammals remains elusive. Herein, we investigated a role of GPR26 in regulating energy homeostasis by generating mice with targeted deletion of the GPR26 gene. We show that GPR26 deficiency causes hyperphagia and hypometabolism, leading to early onset of diet-induced obesity. Accordingly, GPR26 deficiency also caused metabolic complications commonly associated with obesity, including glucose intolerance, hyperinsulinemia, and dyslipidemia. Moreover, consistent with hyperphagia in GPR26 null mice, GPR26 deficiency significantly increased hypothalamic activity of AMPK, a key signaling event that stimulates appetite. In further support of a regulatory role of GPR26 in satiety, GPR26 knockout mice also demonstrate hypersensitivity to treatment of rimonabant, an endocannabinoid receptor-1 antagonist commonly used to treat obesity by suppressing appetite in humans. Together, these findings identified a key role of GPR26 as a central regulator of energy homeostasis though modulation of hypothalamic AMPK activation. PMID:22815809

Hyperlipoproteinemia (HLP) and dyslipidemia (DLP) are of course mainly perceived as diseases of common incidence and are typically seen as the greatest risk factors (RF) in the context of the pandemic of cardiovascular diseases. This is certainly true and HLP or DLP overall affect tens of percents of adults. However we cannot overlook the fact that disorders (mostly congenital) of lipid metabolism exist which, though not formally defined as such, amply satisfy the conditions for classification as rare diseases. Our account only includes a brief overview of the rare HLPs based on the dominant disorder of lipid metabolism, i.e. we shall mention the rare primary forms of hypercholesterolemia, primary forms of hypertriglyceridemia and the rare primary combined forms of HLP. In recent years an amazing progress has been reached relating to these diseases, in particular in the area of exact identification of the genetic defect and the mechanism of defect formation, however each of these diseases would require a separate article, though outside the field of clinical internal medicine. Therefore we shall discuss homozygous familial hypercholesterolemia (FH) in greater depth, partially also the "severe" form of heterozygous FH and in the following part the lipoprotein lipase deficiency; that means, diseases which present an extreme and even fatal risk for their carriers at a young age, but on the other hand, new therapeutic possibilities are offered within their treatment. An internist then should be alert to the suspicion that the described diseases may be involved, know about their main symptoms, where to refer the patient and how to treat them. Also dysbetalipoproteinemia (or type III HLP) will be briefly mentioned. Homozygous FH occurs with the frequency of 1 : 1 000 000 (maybe even more frequently, 1 : 160 000), it is characterized by severe isolated hypercholesterolemia (overall cholesterol typically equal to 15 mmol/l or more), xanthomatosis and first of all by

OBJECTIVE We evaluated the metabolic effects and tolerability of GFT505, a novel dual peroxisome proliferator–activated receptor α/δ agonist, in abdominally obese patients with either combined dyslipidemia or prediabetes. RESEARCH DESIGN AND METHODS The S1 study was conducted in 94 patients with combined dyslipidemia while the S2 study was conducted in 47 patients with prediabetes. Participants were randomly assigned in a double-blind manner to GFT505 at 80 mg/day or placebo for 28 (S1) or 35 (S2) days. Primary efficacy end points were changes from baseline at week 4 in both fasting plasma triglycerides and HDL cholesterol in the S1 group and 2-h glucose upon oral glucose tolerance test in the S2 group. RESULTS In comparison with placebo, GFT505 significantly reduced fasting plasma triglycerides (S1: least squares means −16.7% [95% one-sided CI −∞ to −5.3], P = 0.005; S2: −24.8% [−∞ to −10.5], P = 0.0003) and increased HDL cholesterol (S1: 7.8% [3.0 to ∞], P = 0.004; S2: 9.3% [1.7 to ∞], P = 0.009) in both studies, whereas LDL cholesterol only decreased in S2 (−11.0% [ −∞ to −3.5], P = 0.002). In S2, GFT505 did not reduce 2-h glucose (−0.52 mmol/L [−∞ to 0.61], P = 0.18) but led to a significant decrease of homeostasis model assessment of insulin resistance (−31.4% [−∞ to 12.5], P = 0.001), fasting plasma glucose (−0.37 mmol/L [−∞ to −0.10], P = 0.01) and fructosamine (−3.6% [−∞ to −0.20], P = 0.02). GFT505 also reduced γ glutamyl transferase levels in both studies (S1: −19.9% [−∞ to −12.8], P < 0.0001; S2: −15.1% [−∞ to −1.1], P = 0.004). No specific adverse safety signals were reported during the studies. CONCLUSIONS GFT505 may be considered a new drug candidate for the treatment of lipid and glucose disorders associated with the metabolic syndrome. PMID:21816979

Compelling evidence supports the effectiveness of the reduction of total and LDL cholesterol (TC and LDL-C) in primarily preventing cardiovascular events, within the framework of life-long prevention programs mainly consisting in lifestyle changes. Pharmacological treatment should be introduced when lifestyle changes, including use of nutraceuticals, have failed. ESC/EAS guidelines list a number of nutraceutical compounds and functional foods which have been individually studied in randomized, controlled clinical trials (RCTs). To date only a proprietary formulation of three naturally occurring substances with putative complementary lipid-lowering properties - red yeast rice, policosanol and berberine - combined with folic acid, astaxanthin, and coenzyme Q10 (Armolipid Plus ® ) has been extensively investigated in several RCTs, 7 of which were placebo-controlled, 2 were ezetimibe comparators and 4 were "real life" studies comparing diet and Armolipid Plus to diet alone. The trials included mostly patients with mild to moderate dyslipidemia, treated for 6-48 weeks. The trials also included special populations and patients in whom statins were contraindicated or who could not tolerate them. Armolipid Plus has proved to be able to achieve significant reductions in TC (11-21%) and in LDL-C (15-31%) levels, which is equivalent to expectations from low dose statins. In patients intolerant to statins, who do not achieve their therapeutic target with ezetimibe, Armolipid Plus can achieve a further 10% improvement in TC and LDL-C. The safety and tolerability of Armolipid Plus were excellent, thought likely due to the intentional combination of low doses of its active ingredients: low enough not to be associated with untoward effects, but high enough to exert therapeutic effects in combination with other complementary substances. Consequently, in the event of intolerance to statins, Armolipid Plus offers an effective alternative, which is devoid of the safety risks

Individually, diabetes mellitus, hypertension, and dyslipidemia have been shown to increase the risk of cardiovascular disease. While traditional management of Type 2 diabetes has focused mainly on glycemic control, robust evidence supports the integration of hypertension and dyslipidemia management to reduce the risk of cardiovascular disease. The primary objective of this study was to assess the level of control of blood glucose, blood pressure, and blood lipids (3Bs) among patients with type 2 diabetes. An additional objective was to investigate the impact of hospital type, physician specialty, treatment pattern, and patient profile on clinical outcomes. This was a cross-sectional, multicenter observational study. A nationally representative sample of outpatients with established type 2 diabetes were enrolled at hospitals representative of geographic regions, tiers, and physician specialties in China. Main clinical measurements were the levels of glycosylated hemoglobin (HbA1c), blood pressure, and total serum cholesterol in reference to target goals. A total of 25,817 adults with type 2 diabetes (mean age 62.6 years, 47% male) were enrolled at 104 hospitals. Seventy-two percent reported comorbid hypertension, dyslipidemia, or both. Patients with concurrent type 2 diabetes, hypertension, and dyslipidemia were 6 times more likely to report a prior history of cardiovascular disease compared with those with type 2 diabetes alone. The mean HbA1c level was 7.6%. While 47.7%, 28.4%, and 36.1% of patients achieved the individual target goals for control of blood glucose (HbA1c <7%), blood pressure (systolic blood pressure <130 mm Hg, diastolic blood pressure <80 mm Hg), and blood lipids (total cholesterol <4.5 mmol/L), respectively, only 5.6% achieved all 3 target goals. Lower body mass index (<24 kg/m(2)), no active smoking or drinking, higher education, and diabetes duration <5 years were independent predictors of better cardiovascular disease risk control

Chronic kidney disease (CKD) is a world-wide health concern associated with a significantly higher cardiovascular morbidity and mortality. One of the principal cardiovascular risk factors is the lipid profile. CKD patients have a more frequent and progressive atheromatous disease that cannot be explained by the classical lipid parameters used in the daily clinical practice. Areas covered: The current review summarizes prevailing knowledge on the role of lipids in atheromathosis in CKD patients, including an overview of lipoprotein metabolism highlighting the CKD-induced alterations. Moreover, to obtain information beyond traditional lipid parameters, new state-of-the-art technologies such as lipoprotein subfraction profiling and lipidomics are also reviewed. Finally, we analyse the potential of new lipoprotein subclasses as therapeutic targets in CKD. Expert opinion: The CKD-induced lipid profile has specific features distinct from the general population. Besides quantitative alterations, renal patients have a plethora of qualitative lipid alterations that cannot be detected by routine determinations and are responsible for the excess of cardiovascular risk. New parameters, such as lipoprotein particle number and size, together with new biomarkers obtained by lipidomics will personalize the management of these patients. Therefore, nephrologists need to be aware of new insights into lipoprotein metabolism to improve cardiovascular risk assessment.

Metabolic syndrome, dyslipidemia, hypertension and type 2 diabetes in youth: from diagnosis to treatment

PubMed Central

2010-01-01

Overweight and obesity in youth is a worldwide public health problem. Overweight and obesity in childhood and adolescents have a substantial effect upon many systems, resulting in clinical conditions such as metabolic syndrome, early atherosclerosis, dyslipidemia, hypertension and type 2 diabetes (T2D). Obesity and the type of body fat distribution are still the core aspects of insulin resistance and seem to be the physiopathologic links common to metabolic syndrome, cardiovascular disease and T2D. The earlier the appearance of the clustering of risk factors and the higher the time of exposure, the greater will be the chance of developing coronary disease with a more severe endpoint. The age when the event may occur seems to be related to the presence and aggregation of risk factors throughout life. The treatment in this age-group is non pharmacological and aims at promoting changes in lifestyle. However, pharmacological treatments are indicated in special situations. The major goals in dietary treatments are not only limited to weight loss, but also to an improvement in the quality of life. Modification of risk factors associated to comorbidities, personal satisfaction of the child or adolescent and trying to establish healthy life habits from an early age are also important. There is a continuous debate on the best possible exercise to do, for children or adolescents, in order to lose weight. The prescription of physical activity to children and adolescents requires extensive integrated work among multidisciplinary teams, patients and their families, in order to reach therapeutic success. The most important conclusion drawn from this symposium was that if the growing prevalence of overweight and obesity continues at this pace, the result will be a population of children and adolescents with metabolic syndrome. This would lead to high mortality rates in young adults, changing the current increasing trend of worldwide longevity. Government actions and a better

Childhood obesity is a major health problem with serious long-term metabolic consequences. CD36 is important for the development of obesity-related complications among adults. We aimed to investigate circulating sCD36 during weight loss in childhood obesity and its associations with insulin resistance, dyslipidemia, hepatic fat accumulation and low-grade inflammation. The impact of a 10-week weight loss camp for obese children (N=113) on plasma sCD36 and further after a 12-month follow-up (N=68) was investigated. Clinical and biochemical data were collected, and sCD36 was measured by an in-house assay. Liver fat was estimated by ultrasonography and insulin resistance by the homeostasis model assessment (HOMA-IR). Along with marked weight loss, sCD36 was reduced by 21% (P=0.0013) following lifestyle intervention, and individual sCD36 reductions were significantly associated with the corresponding decreases in HOMA-IR, triglycerides and total cholesterol. The largest sCD36 decrease occurred among children who reduced HOMA-IR and liver fat. After 12 months of follow-up, sCD36 was increased (P=0.014) and the metabolic improvements were largely lost. Weight-loss-induced sCD36 reduction, coincident with improved insulin resistance, circulating lipids and hepatic fat accumulation, proposes that sCD36 may be an early marker of long-term health risk associated with obesity-related complications.

Fatty acid binding protein-4 (FABP4) and FABP5 are two closely related FA binding proteins expressed primarily in adipose tissue and/or macrophages. The small-molecule FABP4 inhibitor BMS309403 was previously reported to improve insulin sensitivity in leptin-deficient Lepob/Lepob (ob/ob) mice. However, this compound was not extensively characterized in the more physiologically relevant animal model of mice with diet-induced obesity (DIO). Here, we report the discovery and characterization of a novel series of FABP4/5 dual inhibitors represented by Compounds 1–3. Compared with BMS309403, the compounds had significant in vitro potency toward both FABP4 and FABP5. In cell-based assays, Compounds 2 and 3 were more potent than BMS309403 to inhibit lipolysis in 3T3-L1 adipocytes and in primary human adipocytes. They also inhibited MCP-1 release from THP-1 macrophages as well as from primary human macrophages. When chronically administered to DIO mice, BMS309403 and Compound 3 reduced plasma triglyceride and free FA levels. Compound 3 reduced plasma free FAs at a lower dose level than BMS309403. However, no significant change was observed in insulin, glucose, or glucose tolerance. Our results indicate that the FABP4/5 inhibitors ameliorate dyslipidemia but not insulin resistance in DIO mice.

Individuals working in information technology (IT) industries suffer from high work stress, possibly causing adverse impacts on their health. However, studies of cardiovascular risk factors among these workers are lacking. The aims of this study were to evaluate the estimated risk for coronary heart disease (CHD) and prevalence of dyslipidemia among IT workers. A total of 941 employees from 11 IT companies were enrolled and the anthropometrics and serum lipid profiles were measured. The 10-year risk for CHD was calculated based on the Framingham risk score. Compared with lipid profiles in a representative sample (n=6589), IT workers had a significantly higher prevalence of obesity, hypercholesterolemia, low level of HDL-C, and high level of LDL-C in each age group. Their overall estimated 10-year risk for CHD was higher than the average risk of an age- and gender-matched population (2.91% vs. 2.79%, p=0.027). Working for more than 10h/day was associated with a higher estimated CHD risk (3.62% vs. 2.54%, p<0.01). A higher prevalence of hyperlipidemia was noted among IT workers. Their estimated 10-year CHD risk was also higher than average. More aggressive interventions to reduce the risk of CHD in this population are needed. Copyright © 2010 Elsevier B.V.

Primary biliary cirrhosis (PBC) is frequently associated with hypercholesterolemia and with an increased cardiovascular morbidity and mortality. Statins lower serum cholesterol levels and may thus improve the cardiovascular risk in PBC patients. The aim of our study was to prospectively examine the efficacy of low-dose atorvastatin on cholestasis as well as cardiovascular risk markers such as dyslipidemia and vascular function in patients with PBC. Nineteen patients with early-stage (biopsy proven and AMA positive) PBC and low-density lipoprotein cholesterol (LDL-C) above 130mg/dL were included in this single-center study and treated with atorvastatin 10mg per day for one year. Concentrations of total cholesterol, LDL-C, LDL triglycerides, oxLDL, IgG and sVCAM-1 decreased significantly after 48 weeks of atorvastatin treatment. Flow-mediated dilation (FMD) of the brachial artery as an indicator of vascular function significantly increased, while carotid artery intima-media thickness and vascular wall stiffness did not progress under treatment. No statistical differences in liver enzymes were observed except a transient increase of alkaline phosphatase. Treatment with low-dose atorvastatin is safe in early-stage PBC, effectively reduces total cholesterol, LDL-C, LDL triglycerides, oxLDL and sVCAM-1 and improves vascular function as reflected by FMD, without affecting cholestasis progression. Therefore, statin therapy should be considered in PBC patients with additional risk factors for cardiovascular disease.

Hunteria umbellata is used in the management and treatment of diabetes and obesity in Nigeria. This study evaluates the effect of aqueous seed extract of Hunteria umbellata on insulin resistance, dyslipidemia, inflammation and oxidative stress in high-fructose diet-induced metabolic syndrome MATERIALS AND METHODS: Rats were randomized into seven groups (A-G). Control (group A) and group C rats received control diet for nine weeks while rats in groups B, D - G were placed on high-fructose diet for 9 weeks. In addition to the diets, groups C - F rats orally received 400, 100, 200 and 400mg/kg body weight aqueous seed extract of Hunteria umbellata for 3 weeks starting from 6th - 9th week. High-fructose diet (when compared to control rats) mediated a significant (p<0.05) increase in body weight, body mass index and abdominal circumference. Similarly, levels of blood glucose, insulin, leptin, adiponectin and insulin resistance were increased. It also caused a significant increase in the levels of cholesterol, triglycerides, low-density lipoprotein cholesterol, very low-density lipoprotein cholesterol, atherogenic index, cardiac index and coronary artery index while high-density lipoprotein cholesterol was decreased significantly. Levels of proinflammatory factor, tumour necrosis factor-α, interleukin-6 and 8 were also increased by the high fructose diet. Moreover, it mediated decrease in activities of superoxide dismutase, catalase, glutathione peroxidase, glutathione reductase, glucose 6-phosphate dehydrogenase and level of glutathione reduced. Conversely, levels of malondialdehyde, conjugated dienes, lipid hydroperoxides, protein carbonyl and fragmented DNA were elevated. Aqueous seed extract of Hunteria umbellata significantly ameliorated the high fructose diet-mediated alterations. From this study, it is concluded that aqueous seed extract of Hunteria umbellata possesses hypoglycemic, hypolipidemic and antioxidants abilities as evident from its capability to

There is a physiologic elevation of total cholesterol (TC) and triglycerides (TG) during pregnancy. Some authors define dyslipidemia (DLP) in pregnant women when TC, LDL and TG concentrations are above the 95th percentile (p95%) and HDL concentration is below the 5th percentile (P5%) for gestational age (GA). To compare the prevalence of DLP in pregnant women using percentiles criteria with the V Brazilian Guidelines on Dyslipidemia and the association with maternal and fetal outcomes. Pregnant women with high-risk conditions, aged 18-50 years, and at least one lipid profile during pregnancy was classified as the presence of DLP by two diagnostic criteria. Clinical and laboratorial data of mothers and newborns were evaluated. 433 pregnant women aged 32.9 ± 6.5 years were studied. Most (54.6%) had lipid profile collected during third trimester. The prevalence of any lipid abnormalities according to the criteria of the National Guidelines was 83.8%: TC ≥ 200 mg/dL was found in 49.9%; LDL ≥ 160 mg/dL, in 14.3%, HDL ≤ 50 mg/dL in 44.4% and TG ≥ 150 mg/dL in 65.3%. Any changes of lipid according to percentiles criteria was found in 19.6%: elevation above the P95% for TC was found in 0.7%; for LDL, 1.7%; for TG 6.4% and HDL lower than the P5% in 13%. The frequency of comorbidity: hypertension, diabetes, smoking, obesity and preeclampsia was similar among pregnant women when DLP was compared by both criteria. The prevalence of DLP during pregnancy varies significantly depending on the criteria used, however none demonstrated superiority in association with comorbidities. Durante a gestação ocorrem, fisiologicamente, elevações do colesterol total (CT) e triglicerídios (TG). Alguns autores definem dislipidemia (DLP) gestacional quando as concentrações de CT, LDL e TG são superiores ao percentil 95 (P95%) e de HDL, inferiores ao percentil 5 (P5%) para a idade gestacional.

A PC based system has been developed for the analysis of gamma-ray spectra and for the complete reduction of data from INAA experiments, including software to average the results from mulitple lines and multiple countings and to produce a final report of analysis. Graphics algorithms may be called for the analysis of complex spectral features, to compare the data from alternate photopeaks and to evaluate detector performance during a given counting cycle. A database of results for control samples can be used to prepare quality control charts to evaluate long term precision and to search for systemic variations in data on reference samples as a function of time. The entire software library can be accessed through a user-friendly menu interface with internal help.

Evaluation critique of state of the art dyslipidemia management in general and with a special emphasis on the Indian population.

Classically, there have been three well established major cardiovascular risk factors, hypercholesterolemia, hypertension and tobacco abuse. With accumulating clinical evidence, diabetes can now be added as a fourth major risk factor. Much interest in various other risk factors and possible causative factors has been generated, but it should be remembered that of all these, low density lipoproteins (LDL) remains the gold standard for evaluating risk. The common perception is that only caucasians in the western world have significant cardiovascular (CV) risk. However, much clinical information to the contrary has accumulated and now it is realized that many other ethnic groups also have significant CV disease, such as in India, especially in the urban population. Dyslipidemias of specific lipoproteins and their treatment is an important part of understanding and managing CV disease and risk. Various plasma factors such as homocysteine and lipoprotein (a) [(a)] have been considered to have definite associations with CV disease, but any treatment benefit remains in doubt. In addition, inflammatory risk factors are considered to be of significant clinical interest, especially high sensitivity C-Reactive protein (hsCRP). Where do these factors fit into routine clinical practice still awaits clarification. Only two of these inflammatory risk (Lp-factors can be tested commercially on a routine clinical basis and these are hsCRP and Lipoprotein-associated Phospholipase A2 Lp-PLA2). Their clinical utillity is not established and acceptance is limited: some third party health coverage organizations refuse to pay for such analyses. In the past, women have been looked upon as not having significant CV disease. More recently, evidence suggests that women may have more CV disease than men, and that physicians may have failed to realize this and act accordingly. The true situation is that women have less CV disease than men prior to menopause and then they slowly catch up

Plasma free amino acid (PFAA) profile is highlighted in its association with visceral obesity and hyperinsulinemia, and future diabetes. Indeed PFAA profiling potentially can evaluate individuals’ future risks of developing lifestyle-related diseases, in addition to diabetes. However, few studies have been performed especially in Asian populations, about the optimal combination of PFAAs for evaluating health risks. We quantified PFAA levels in 3,701 Japanese subjects, and determined visceral fat area (VFA) and two-hour post-challenge insulin (Ins120 min) values in 865 and 1,160 subjects, respectively. Then, models between PFAA levels and the VFA or Ins120 min values were constructed by multiple linear regression analysis with variable selection. Finally, a cohort study of 2,984 subjects to examine capabilities of the obtained models for predicting four-year risk of developing new-onset lifestyle-related diseases was conducted. The correlation coefficients of the obtained PFAA models against VFA or Ins120 min were higher than single PFAA level. Our models work well for future risk prediction. Even after adjusting for commonly accepted multiple risk factors, these models can predict future development of diabetes, metabolic syndrome, and dyslipidemia. PFAA profiles confer independent and differing contributions to increasing the lifestyle-related disease risks in addition to the currently known factors in a general Japanese population.

We investigated whether intensive glycemic control, combination therapy for dyslipidemia, and intensive blood-pressure control would limit the progression of diabetic retinopathy in persons with type 2 diabetes. Previous data suggest that these systemic factors may be important in the development and progression of diabetic retinopathy. In a randomized trial, we enrolled 10,251 participants with type 2 diabetes who were at high risk for cardiovascular disease to receive either intensive or standard treatment for glycemia (target glycated hemoglobin level, <6.0% or 7.0 to 7.9%, respectively) and also for dyslipidemia (160 mg daily of fenofibrate plus simvastatin or placebo plus simvastatin) or for systolic blood-pressure control (target, <120 or <140 mm Hg). A subgroup of 2856 participants was evaluated for the effects of these interventions at 4 years on the progression of diabetic retinopathy by 3 or more steps on the Early Treatment Diabetic Retinopathy Study Severity Scale (as assessed from seven-field stereoscopic fundus photographs, with 17 possible steps and a higher number of steps indicating greater severity) or the development of diabetic retinopathy necessitating laser photocoagulation or vitrectomy. At 4 years, the rates of progression of diabetic retinopathy were 7.3% with intensive glycemia treatment, versus 10.4% with standard therapy (adjusted odds ratio, 0.67; 95% confidence interval [CI], 0.51 to 0.87; P=0.003); 6.5% with fenofibrate for intensive dyslipidemia therapy, versus 10.2% with placebo (adjusted odds ratio, 0.60; 95% CI, 0.42 to 0.87; P=0.006); and 10.4% with intensive blood-pressure therapy, versus 8.8% with standard therapy (adjusted odds ratio, 1.23; 95% CI, 0.84 to 1.79; P=0.29). Intensive glycemic control and intensive combination treatment of dyslipidemia, but not intensive blood-pressure control, reduced the rate of progression of diabetic retinopathy.

Recently, the association of plasma free amino acid (PFAA) profile and lifestyle-related diseases has been reported. However, few studies have been reported in large Asian populations, about the usefulness of PFAAs for evaluating disease risks. We examined the ability of PFAA profiles to evaluate lifestyle-related diseases in so far the largest Asian population. We examined plasma concentrations of 19 amino acids in 8589 Japanese subjects, and determined the association with variables associated with obesity, blood glucose, lipid, and blood pressure. We also evaluated the PFAA indexes that reflect visceral fat obesity and insulin resistance. The contribution of single PFAA level and relevant PFAA indexes was also examined in the risk assessment of lifestyle-related diseases. Of the 19 amino acids, branched-chain amino acids and aromatic amino acids showed association with obesity and lipid variables. The PFAA index related to visceral fat obesity showed relatively higher correlation with variables than that of any PFAA. In the evaluation of lifestyle-related disease risks, the odds ratios of the PFAA index related to visceral fat obesity or insulin resistance with the diseases were higher than most of those of individual amino acid levels even after adjusting for potential confounding factors. The association pattern of the indexes and PFAA with each lifestyle-related disease was distinct. We confirmed the usefulness of PFAA profiles and indexes as markers for evaluating the risks of lifestyle-related diseases, including diabetes mellitus, metabolic syndrome, dyslipidemia, and hypertension in a large Asian population.

Despite clear guideline recommendations, there is a growing body of evidence that there is suboptimal use of lipid-lowering treatment in Canadians. To assess the prevalence and types of persistent lipid abnormalities in Canadian patients receiving statin therapy. The present cross-sectional study recruited 2436 outpatients 45 years of age or older who were treated with statins by 232 physicians from 10 provinces; all underwent clinical examination and had their latest fasting lipid values while on statin therapy recorded. The median patient age was 66 years (interquartile range [IQR] 58 to 74 years), 60% were men and 80% were in the high 10-year risk category. The median low-density lipoprotein cholesterol level was 2.0 mmol/L (IQR 1.6 mmol/L to 2.5 mmol/L) and the median total cholesterol/high-density lipoprotein cholesterol ratio was 3.4 mmol/L (IQR 2.8 mmol/L to 4.1 mmol/L). However, based on the 2006 Canadian Cardiovascular Society recommendations, 37% of all patients did not have a low-density lipoprotein cholesterol level at goal or intervention target level, including 45% of high-risk category patients. The majority of patients received atorvastatin (50%) or rosuvastatin (37%) but primarily at low-to-medium doses, and a minority (14%) received additional lipid-modifying therapies. The present observational study highlights the need for more intensive treatment of lipid abnormalities, particularly among high-risk patients. Recognizing several important limitations related to the observational nature of the study, the findings suggest the possibility that, in addition to optimizing adherence, there remains an important need to titrate current statin therapy to higher doses and potentially use a combination of lipid-modifying treatments (once the statin dose has been truly maximized) to further bridge the gap between evidence-based medicine and current Canadian practice.

Dyslipidemia is common in nephrotic children and persistent lipid abnormalities are risk factor of late vascular complications. The aim of the study was evaluation of efficacy and safety of 12-months simvastatin therapy in nephrotic children with lipid profile abnormalities present despite clinical remission lasting for at least 8 weeks, including ultrasonographic assessment of carotid and femoral arteries. Overall 52 children (40 steroid-dependent and 12 steroid-resistant) were initially introduced to the study and 29 of them were treated with simvastatin. Normalisation of lipid profile was achieved in 19/29 (65.5%) and improvement in 9/29 (31%). Significant reduction in total cholesterol (p < 0.00001), LDL-C (p < 0.000003), VLDL- (p < 0.0123), oxy-LDL-C fractions (p < 0.0002) and triglycerides (TG) (p < 0.0005) serum concentration was achieved in non-proteinuric patients. Analysis of the intima-media thickness (IMT) of the common carotid (c) and superficial femoral (f) arteries values revealed positive correlation between baseline cIMT and VLDL-C (p = 0.038) and TG concentration (p = 0.008), as well as positive correlation between fIMT and baseline creatinine (p = 0.04) and LDL-C serum concentration (p = 0.032) after simvastatine treatment. Number of children with significant vessels pathology (Z-score > 2.0) was small. Increased cIMT was seen at baseline in 4 patients and in 5 after simvastatin treatment, however average and Z-score values in children under simvastatin treatment have decreased. Increased fIMT values were seen at baseline in 2 and in one case after simvastatin treatment. Tolerance of simvastation was very good in all cases but one. Simvastatin therapy was effective and safe in nephrotic non-proteinuric children with abnormal lipid profile. Fair estimation of impact of the 12-months simvastatin therapy on vascular status was not available due to limited number of children with significantly increased IMT at baseline.

One of the tissues or organs affected by diabetes is the nervous system, predominantly the peripheral system (peripheral polyneuropathy and/or painful peripheral neuropathy) but also the central system with impaired learning, memory and mental flexibility. The aim of this study was to test the hypothesis that the pre-diabetic or diabetic condition caused by a high-fat diet (HFD) can damage both the peripheral and central nervous systems. Groups of C57BL6 and Swiss Webster mice were fed a diet containing 60% fat for 8 months and compared to control and streptozotocin (STZ)-induced diabetic groups that were fed a standard diet containing 10% fat. Aspects of peripheral nerve function (conduction velocity, thermal sensitivity) and central nervous system function (learning ability, memory) were measured at assorted times during the study. Both strains of mice on HFD developed impaired glucose tolerance, indicative of insulin resistance, but only the C57BL6 mice showed statistically significant hyperglycemia. STZ-diabetic C57BL6 mice developed learning deficits in the Barnes maze after 8 weeks of diabetes, whereas neither C57BL6 nor Swiss Webster mice fed a HFD showed signs of defects at that time point. By 6 months on HFD, Swiss Webster mice developed learning and memory deficits in the Barnes maze test, whereas their peripheral nervous system remained normal. In contrast, C57BL6 mice fed the HFD developed peripheral nerve dysfunction, as indicated by nerve conduction slowing and thermal hyperalgesia, but showed normal learning and memory functions. Our data indicate that STZ-induced diabetes or a HFD can damage both peripheral and central nervous systems, but learning deficits develop more rapidly in insulin-deficient than in insulin-resistant conditions and only in Swiss Webster mice. In addition to insulin impairment, dyslipidemia or adiponectinemia might determine the neuropathy phenotype. © 2014. Published by The Company of Biologists Ltd.

Cardiovascular disease is the leading cause of morbidity and mortality in the United States and therapies aimed at lipid modification are important for the reduction of cardiovascular risk. There have been many exciting advances in lipid management over the recent years. This review discusses these recent advances as well as the direction of future studies. Several recent clinical trials support low-density lipoprotein cholesterol (LDL-c) reduction beyond maximal statin therapy for improved cardiovascular outcomes. Ezetimibe reduced LDL-c beyond maximal statin therapy and was associated with improved cardiovascular outcomes for high-risk populations. Further LDL-c reduction may also be achieved with proprotein convertase subtilisin/kexin type-9 (PCSK9) inhibition and a recent trial, Further Cardiovascular Outcomes Research with PCSK9 Inhibition in Subjects with Elevated Risk (FOURIER), was the first to show reduction in cardiovascular events for evolocumab. Additional outcome studies of monoclonal antibody and RNA-targeted PCSK9 inhibitors are underway. Quantitative high-density lipoprotein cholesterol (HDL-c) improvements have failed to have clinical impact to date; most recently, cholesteryl ester transfer protein inhibitors and apolipoprotein infusions have demonstrated disappointing results. There are still ongoing trials in both of these areas, but some newer therapies are focusing on HDL functionality and not just the absolute HDL-c levels. There are several ongoing studies in triglyceride reduction including fatty acid therapy, inhibition of apolipoprotein C-3 or ANGTPL3 and peroxisome proliferator-activated receptor-α agonists. Lipid management continues to evolve and these advances have the potential to change clinical practice in the coming years.

Koji is made from grains fermented with Aspergillus oryzae and is essential for the production of many traditional Japanese foods. Many previous studies have shown that koji contributes to the improvement of dyslipidemia. However, little is known regarding the underlying mechanism of this effect. Furthermore, the compound contributing to the activation of lipid metabolism is unknown. We demonstrated that rice koji extract (RKE) induces the mRNA expression of peroxisome proliferator-activated receptor alpha (PPARα) target genes, which promotes lipid metabolism in murine hepatocytes. This effect was not observed in PPARα-KO hepatocytes. We also demonstrated that RKE contained linolenic acid (LIA), oleic acid (OA), and hydroxyoctadecadienoic acids (HODEs), which activate PPARα, using LC-MS analysis. Our findings suggest that RKE, containing LIA, OA, and HODEs, could be valuable in improving dyslipidemia via PPARα activation.

The impact of host genetic factors on the incidence of dyslipidemia in antiretroviral-naive HIV patients starting antiretroviral therapy (ART) is not clear. We assessed the role of single nucleotide polymorphisms (SNPs) identified from previous genome-wide association studies adjusting for the contribution of nongenetic factors. We assessed 192 SNPs in an HIV cohort who started ART (1997-2008) including a protease inhibitor or a nonnucleoside reverse transcriptase inhibitor (NNRTI). Patients had fasting plasma lipids, total cholesterol (T-Chol), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C) and triglycerides measured prior to their ART initiation and after 1 year. A logistic regression model was constructed and multiple test was corrected using 10% false discovery rate (FDR). Haplotypes and gene interactions were analysed. A total of 727 individuals were successfully genotyped (n = 381_PI-group; n = 346_NNRTI-group). Age and hepatitis C virus (HCV) coinfection were associated with increases and decreases in T-Chol and LDL-C (P < 0.01), respectively. Protease inhibitor containing ART showed an unfavourable association with T-Chol (P < 0.01) and triglycerides (P = 7.4E-4) and NNRTI-containing ART was favourably associated with HDL-C (P < 0.01). Moreover, SNPs in apolipoprotein B (APOB) were associated with an increase of LDL-C [rs10495712 (P = 3.18E-4); rs754524 (P = 1.26E-3)]. Six SNPs in three genes showed an association with a favourable effect on HDL-C levels when ART included NNRTI: ABCA1 (rs4149313, P = 2.97E-4), LIPC (rs1800588, P = 2.13E-3; rs473224, P = 3.06E-4; rs261336, P = 2.23E-3) and CETP (rs173539, P = 2.96E-3; rs3764261, P = 1.52E-3). After 10% FDR correction for multiple testing, one and six SNPs displayed significant associations with LDL-C and HDL-C, respectively. In HIV-infected patients staring ART, one SNP in APOB was associated with an increase

Subclinical hypothyroidism (SH) is defined as an elevated serum thyroid-stimulating hormone (TSH) level with free thyroxine (fT4) level in the normal range. There are very few studies in the literature reporting on the effect of SH on lipid metabolism and carotid intima-media thickness (CIMT) in children. The study included 38 children diagnosed with SH and a control group comprising 38 healthy, euthyroid children. SH was diagnosed based on an elevated TSH level (4.2-20 mIU/L) and normal fT4 level measured in two morning fasting blood samples obtained at an interval of 2 to 6 weeks. Blood samples were collected by venipuncture in the morning after an overnight fast. The patient group included 38 children (16 male, 22 female) with SH and the control group -38 healthy, euthyroid children (20 male, 18 female). Mean age was 8.1±3.6 (range, 3.5-15) years in the patient group and 8.9±2.4 (range, 4.5-15) years in the control group. In the patient group, total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), TC/high-density lipoprotein cholesterol (HDL-C), and LDL-C/HDL-C were higher compared to the control group (p=0.049, p=0.014, p=0.002, and 0.003, respectively). In the patient group, CIMT was also significantly higher compared to the control group (p=0.001). The patient group was further divided into two subgroups based on their serum TSH level: (I) patients with mildly elevated TSH (TSH=4.2±10 mIU/L) (n=33) and (II) patients with high TSH (TSH≥10 mIU/L) (n=5). However, no significant difference was found between the patients with mild and severe SH with regard to TC, LDL-C, HDL-C, triglyceride level and CIMT levels (p=0.635, p=0.424, p=0.310, p=0.342, and 0.610, respectively). Subclinical hypothyroidism leads to increased dyslipidemia (increased TC and LDL) and increased CIMT, which leads to increased risk of cardiovascular disease. Further studies are needed to substantiate these findings in children with SH.

The aim of this study was to carry out a review of margins that should be used for the delineation of target volumes in lung cancer, with a focus on margins from gross tumour volume (GTV) to clinical target volume (CTV) and internal target volume (ITV) delineation. Our review was based on a PubMed literature search with, as a cornerstone, the 2010 European Organisation for Research and Treatment of Cancer (EORTC) recommandations by De Ruysscher et al. The keywords used for the search were: radiotherapy, lung cancer, clinical target volume, internal target volume. The relevant information was categorized under the following headings: gross tumour volume definition (GTV), CTV-GTV margin (first tumoural CTV then nodal CTV definition), in field versus elective nodal irradiation, metabolic imaging role through the input of the PET scanner for tumour target volume and limitations of PET-CT imaging for nodal target volume definition, postoperative radiotherapy target volume definition, delineation of target volumes after induction chemotherapy; then the internal target volume is specified as well as tumoural mobility for lung cancer and respiratory gating techniques. Finally, a chapter is dedicated to planning target volume definition and another to small cell lung cancer. For each heading, the most relevant and recent clinical trials and publications are mentioned. Copyright © 2013. Published by Elsevier SAS.

Comparative cardiovascular risk factor care across North America is unknown. We aimed to determine current performance in Canada and the United States (US). A systematic review was conducted of Medline and EMBASE (to June 1, 2014). Eligible studies reported on screening, awareness, treatment, or control rates for hypertension, dyslipidemia, diabetes, and smoking. Categorical performance 'ratings' on the basis of the most successful US health plans were used to classify rates as suboptimal (< 50%), below target (50%-70%), above target (70%-90%), or optimal (> 90%). A total of 127 studies reporting on 10,510,324 individuals across North America were included. Hypertension awareness (84.3%) and treatment (82.0%) rates in Canada and the US (82.7% and 75.6%, respectively) were above target, whereas control in both nations was below target (68.1% vs 51.8%, respectively). Canadian awareness, treatment, and control rates for dyslipidemia (42.7%, 40.9%, and 41.5%, respectively) were suboptimal, and American indicators were generally below target (61.5%, 43.0%, and 63.6%, respectively). Canada and the US showed diabetes awareness (88.2% vs 86.8%) and treatment rates (82.3% vs 82.5%) above target. However, glucose control was suboptimal in Canada (35.3%), and below target in the US (58.8%). There was a modest decline in absolute smoking prevalence rates in Canada from 1999 to 2013 (25.2% to 14.6%). Screening for tobacco use (72.2%) and counselling rates (73.8%) in the US were above target. Substantial variation exists in cardiovascular risk factor care across North America. Standardized reporting, dissemination of practice guidelines, and setting explicit goal-directed targets for performance might facilitate improvement.

The objective of this study was to assess the proportion of patients with type 2 diabetes mellitus (T2DM) attaining individual and combined targets of low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), triglycerides (TG), non-HDL-C, and apolipoprotein B (ApoB) after treatment with rosuvastatin (R) + fenofibric acid (FA) compared with corresponding-dose R monotherapy. This post hoc analysis evaluated data from the T2DM subset of patients with mixed dyslipidemia (LDL-C ≥130 mg/dL, HDL-C <40/50 mg/dL in men/women, and TG ≥150 mg/dL) from 2 randomized studies. Patients included in the analysis (N = 456) were treated with R (5, 10, or 20 mg), FA 135 mg, or R (5, 10, or 20 mg) + FA 135 mg for 12 weeks. Attainment of LDL-C <100 mg/dL, HDL-C >40/50 mg/dL in men/women, TG <150 mg/dL, non-HDL-C <130 mg/dL, ApoB <90 mg/dL, and the combined targets of these parameters was assessed. Treatment with R + FA resulted in a significantly higher proportion of patients achieving optimal levels of HDL-C (46.8% vs. 20.8%, P = 0.009 for R 10 mg + FA), TG (60.0% vs. 34.0%, P = 0.02 for R 10 mg + FA; 54.0% vs. 26.4%, P = 0.005 for R 20 mg + FA), non-HDL-C (55.1% vs. 36.4%, P = 0.04 for R 5 mg + FA), ApoB (58.0% vs. 36.4%, P = 0.02 for R 5 mg + FA); and the combined targets of LDL-C, HDL-C, and TG (28.3% vs. 8.3%, P = 0.02 for R 10 mg + FA) and all 5 parameters (26.1% vs. 8.3%, P = 0.03 for R 10 mg + FA) than corresponding-dose R monotherapies. A significantly greater proportion of T2DM patients achieved individual and combined lipid targets when treated with the combination of R + FA than corresponding-dose R monotherapies.

The aim of this study was to assess the prevalence of atherogenic dyslipidemia (AD) and the lipid triad (LT) in the working population in Spain, their associated variables and how far they are linked to cardiovascular risk (CVR). Observational cross-sectional study of 70,609 workers (71.5% male (M), 28.5% female (F), mean age 39.2 ± 10), who attended medical checkups and agreed to participate. Plasma samples were analysed in a central laboratory. AD definition used was: triglycerides ≥150 mg/dl and HDL cholesterol <40 mg/dl (M)/<50 mg/dl (F) and LT when LDL cholesterol > 160 mg/dl is further added. Univariate comparisons in the absence and presence of AD and LT and the probability of AD according to different parameters and their possible association with CVR were assessed. CVR was stratified following the European SCORE model for low risk-population. 5.7% (95% CI 4.7-6.9) of the working population have AD and 1.1% (95% CI 1.0-1.2) LT. In univariate analysis, workers with AD and LT had a higher prevalence of obesity, hypertension, smoking and diabetes than those who had not (p < 0.001). In multivariate analysis, BMI, sex, age 40-49, diabetes, tobacco, uric acid, LDL or blood pressure significantly influenced the risk of AD. AD was significantly associated with CVR after adjusting for alcohol and obesity. However, most of the AD subjects (91.8%) were classified as low risk. About 6% of the working population in Spain meets AD criteria. Assuming that these subjects have increased CVR, AD allows to identify additional 5% of subjects with increased CVR to that one the SCORE model detects, helping to improve cardiovascular risk stratification.

The relationship between thyroid function and lipid profile has been documented in T2DM and healthy subjects. The aim of the current study was to assess the association between thyroid hormone parameters and dyslipidemia in T2DM and non-diabetic study participants. In this comparative cross-sectional study, 214 type 2 diabetic and 214 non-diabetic study participants were enrolled. Clinical and anthropometric data were collected from all study participants. After overnight fasting, 10ml of whole blood samples were drawn for the measurement of serum TSH, free thyroxine (fT4), free triiodothyronine (fT3), serum reactive C-protein levels, as well as for lipid profile test and glucose. The burden of hypothyroidism and subclinical hypothyroidism among T2DM study participants were 73 (17.05%) and 13 (3.04%) respectively. Comparatively, T2DM study participants had significantly higher serum lipid level than non-diabetics. Stratified by TSH, hypothyroid T2DM study participants had increased lipid level than euthyroid subjects. T2DM serum TSH have shown a positive significant correlation with all lipid profile parameters except HDL-C. In the final model (multivariate linear regression), diabetics serum TSH significantly and positively associated with TG and BMI. Diabetic serum fT3 and fT4 negatively associated with body mass index. In addition, diabetics serum fT3 negatively and serum fT4 positively associated with TC and HDL-C respectively. T2DM study subjects had significantly higher lipid level than nondiabetic and We identified that TSH was positively associated with serum TG and BMI among T2DM study participants.

The aim of this study was to test the hypothesis that patients with atherosclerotic cardiovascular (CV) disease optimally treated on a statin but with residual atherogenic dyslipidemia (low high-density lipoprotein cholesterol [HDL-C] and high triglycerides) will benefit from addition of niacin with fewer CV events compared with placebo. Statin monotherapy trials have found 25%-35% CV risk reduction relative to placebo, leaving significant residual risk. Patients with atherogenic dyslipidemia have substantially increased CV risk. Participants were men and women with established CV disease and atherogenic dyslipidemia. Lipid entry criteria varied by gender and statin dose at screening. All participants received simvastatin (or simvastatin plus ezetimibe) at a dose sufficient to maintain low-density lipoprotein cholesterol (LDL-C) 40-80 mg/dL (1.03-2.07 mmol/L). Participants were randomized to extended-release niacin or matching placebo. The primary end point was time to occurrence of the first of the following: coronary heart disease death, nonfatal myocardial infarction, ischemic stroke, hospitalization for acute coronary syndrome, or symptom-driven coronary or cerebral revascularization. This event-driven trial will have 85% power to show a 25% reduction in primary event frequency after 850 patients have experienced a primary outcome event. AIM-HIGH completed enrollment in April 2010. Follow-up is expected to continue through 2012. AIM-HIGH was designed to determine whether treating residual dyslipidemia with niacin further reduces cardiovascular events in patients with CV disease on a statin at target levels of low-density lipoprotein cholesterol.

Atherogenic mixed dyslipidemia associates with oxidative stress and defective HDL antioxidative function in metabolic syndrome (MetS). The impact of statin treatment on the capacity of HDL to inactivate LDL-derived, redox-active phospholipid hydroperoxides (PCOOHs) in MetS is indeterminate. Insulin-resistant, hypertriglyceridemic, hypertensive, obese males were treated with pitavastatin (4 mg/day) for 180 days, resulting in marked reduction in plasma TGs (−41%) and LDL-cholesterol (−38%), with minor effects on HDL-cholesterol and apoAI. Native plasma LDL (baseline vs. 180 days) was oxidized by aqueous free radicals under mild conditions in vitro either alone or in the presence of the corresponding pre- or poststatin HDL2 or HDL3 at authentic plasma mass ratios. Lipidomic analyses revealed that statin treatment i) reduced the content of oxidizable polyunsaturated phosphatidylcholine (PUPC) species containing DHA and linoleic acid in LDL; ii) preferentially increased the content of PUPC species containing arachidonic acid (AA) in small, dense HDL3; iii) induced significant elevation in the content of phosphatidylcholine and phosphatidylethanolamine (PE) plasmalogens containing AA and DHA in HDL3; and iv) induced formation of HDL3 particles with increased capacity to inactivate PCOOH with formation of redox-inactive phospholipid hydroxide. Statin action attenuated LDL oxidability Concomitantly, the capacity of HDL3 to inactivate redox-active PCOOH was enhanced relative to HDL2, consistent with preferential enrichment of PE plasmalogens and PUPC in HDL3.

Patients with type IIb, or mixed, dyslipidemia have high levels of low-density lipoprotein cholesterol (LDL-C) with predominance of small dense LDL particles, high levels of triglycerides (TG), and low levels of high-density lipoprotein cholesterol (HDL-C). Fenofibrate significantly reduces TG and, more moderately, LDL-C, increases HDL-C and produces a shift from small to large LDL particle size; the main effect of ezetimibe is a reduction in LDL-C levels. Combined treatment with fenofibrate and ezetimibe may correct all the abnormalities of type IIb dyslipidemia. To assess the efficacy and safety of coadministration of fenofibrate (NanoCrystal(R)) and ezetimibe in patients with type IIb dyslipidemia and the metabolic syndrome compared with administration of fenofibrate and ezetimibe alone (ClinicalTrials.gov Identifier: NCT00349284; Study ID: CLF178P 04 01). This was a prospective, randomized, double-blind, three-parallel arm, multicenter, comparative study. Sixty ambulatory patients (mean age 56 years; 50% women, 50% men) were treated in each group. For inclusion in the study, patients were required to have LDL-C >or=4.13 mmol/L (>or=160 mg/dL), TG >or=1.71 mmol/L and or=150 mg/dL and

Rett syndrome (RTT; OMIM 312750), a progressive neurological disorder, is caused by mutations in methyl-CpG-binding protein 2 (MECP2; OMIM 300005), a ubiquitously expressed factor. A genetic suppressor screen designed to identify therapeutic targets surprisingly revealed that downregulation of the cholesterol biosynthesis pathway improves neurological phenotypes in Mecp2 mutant mice. Here, we show that MeCP2 plays a direct role in regulating lipid metabolism. Mecp2 deletion in mice results in a host of severe metabolic defects caused by lipid accumulation, including insulin resistance, fatty liver, perturbed energy utilization, and adipose inflammation by macrophage infiltration. We show that MeCP2 regulates lipid homeostasis by anchoring the repressor complex containing NCoR1 and HDAC3 to its lipogenesis targets in hepatocytes. Consistently, we find that liver targeted deletion of Mecp2 causes fatty liver disease and dyslipidemia similar to HDAC3 liver-specific deletion. These findings position MeCP2 as a novel component in metabolic homeostasis. Rett syndrome patients also show signs of peripheral dyslipidemia; thus, together these data suggest that RTT should be classified as a neurological disorder with systemic metabolic components. We previously showed that treatment of Mecp2 mice with statin drugs alleviated motor symptoms and improved health and longevity. Lipid metabolism is a highly treatable target; therefore, our results shed light on new metabolic pathways for treatment of Rett syndrome. PMID:27288453

Obesity and Its Metabolic Complications: The Role of Adipokines and the Relationship between Obesity, Inflammation, Insulin Resistance, Dyslipidemia and Nonalcoholic Fatty Liver Disease

Accumulating evidence indicates that obesity is closely associated with an increased risk of metabolic diseases such as insulin resistance, type 2 diabetes, dyslipidemia and nonalcoholic fatty liver disease. Obesity results from an imbalance between food intake and energy expenditure, which leads to an excessive accumulation of adipose tissue. Adipose tissue is now recognized not only as a main site of storage of excess energy derived from food intake but also as an endocrine organ. The expansion of adipose tissue produces a number of bioactive substances, known as adipocytokines or adipokines, which trigger chronic low-grade inflammation and interact with a range of processes in many different organs. Although the precise mechanisms are still unclear, dysregulated production or secretion of these adipokines caused by excess adipose tissue and adipose tissue dysfunction can contribute to the development of obesity-related metabolic diseases. In this review, we focus on the role of several adipokines associated with obesity and the potential impact on obesity-related metabolic diseases. Multiple lines evidence provides valuable insights into the roles of adipokines in the development of obesity and its metabolic complications. Further research is still required to fully understand the mechanisms underlying the metabolic actions of a few newly identified adipokines. PMID:24733068

To assess the role of Helicobacter pylori infection and interleukin 6 polymorphism -174 (rs1800795) in dyslipidemia. Case-control study comparing serum lipids between H. pylori positive and negative patients and controlling for IL-6 -174 polymorphism, age, sex and smoking. 3 hospitals performing outpatient endoscopies in the city of Oulu, Finland. 199 adult patients with dyspepsia symptoms fulfilling Rome criteria originating from ethnically Finnish population. Patients with an immunosuppressive disorder or malignant disease, treated H. pylori infection, immunosuppressive or anticoagulant medication, previous gastric surgery or ongoing antibiotic treatment were excluded. Association of H. pylori infection and serum lipid concentrations in the whole group or in genotype-based subgroups. The associations between peptic ulcer, gastric mucosal inflammation and serum lipid concentrations were assessed as secondary outcomes. The median high-density lipoprotein (HDL) serum concentration was significantly lower in the H. pylori positive group (0.81 mmol/L) than in the negative group (0.95 mmol/L; p<0.001). In the genotype subgroup analyses, a similar association between H. pylori infection and HDL serum levels was seen within the IL-6 -174 CC genotype group (HDL 0.72 vs 1.06 mmol/L, respectively; p<0.001), but no significant associations were seen in the GC or GG genotype groups. Additionally, patients with peptic ulcer demonstrated lower HDL levels (0.75 mmol/L) than H. pylori positive patients without ulcer (0.86 mmol/L; p=0.010). H. pylori infection associated significantly with low serum levels of HDL in the IL-6 -174 CC genotype patients but not in the other genotypes. This suggests that the association between H. pylori infection and serum HDL could be transmitted through IL-6. We suggest that the role of IL-6 genotype should also be studied in relation to other associations between gastrointestinal microbiome and cardiovascular risk factors. Published by the BMJ

Endogenous ω-3 Polyunsaturated Fatty Acid Production Confers Resistance to Obesity, Dyslipidemia, and Diabetes in Mice

Despite the well-documented health benefits of ω-3 polyunsaturated fatty acids (PUFAs), their use in clinical management of hyperglycemia and obesity has shown little success. To better define the mechanisms of ω-3 PUFAs in regulating energy balance and insulin sensitivity, we deployed a transgenic mouse model capable of endogenously producing ω-3 PUFAs while reducing ω-6 PUFAs owing to the expression of a Caenorhabditis elegans fat-1 gene encoding an ω-3 fatty acid desaturase. When challenged with high-fat diets, fat-1 mice strongly resisted obesity, diabetes, hypercholesterolemia, and hepatic steatosis. Endogenous elevation of ω-3 PUFAs and reduction of ω-6 PUFAs did not alter the amount of food intake but led to increased energy expenditure in the fat-1 mice. The requirements for the levels of ω-3 PUFAs as well as the ω-6/ω-3 ratios in controlling blood glucose and obesity are much more stringent than those in lipid metabolism. These metabolic phenotypes were accompanied by attenuation of the inflammatory state because tissue levels of prostaglandin E2, leukotriene B4, monocyte chemoattractant protein-1, and TNF-α were significantly decreased. TNF-α–induced nuclear factor-κB signaling was almost completely abolished. Consistent with the reduction in chronic inflammation and a significant increase in peroxisome proliferator–activated receptor-γ activity in the fat-1 liver tissue, hepatic insulin signaling was sharply elevated. The activities of prolipogenic regulators, such as liver X receptor, stearoyl-CoA desaturase-1, and sterol regulatory element binding protein-1 were sharply decreased, whereas the activity of peroxisome proliferator–activated receptor-α, a nuclear receptor that facilitates lipid β-oxidation, was markedly increased. Thus, endogenous conversion of ω-6 to ω-3 PUFAs via fat-1 strongly protects against obesity, diabetes, inflammation, and dyslipidemia and may represent a novel therapeutic modality to treat these prevalent

The peroxisome proliferator-activated receptor (PPAR)-α and -γ agonists, fibrates and glitazones, are effective treatments for dyslipidemia and type 2 diabetes mellitus, respectively, but exhibit class-related, as well as compound-specific safety characteristics. This article reviews the profiles of PPAR-α, PPAR-γ, and dual PPAR-α/γ agonists with regard to class-related and compound-specific efficacy and adverse effects. We explore how learnings from first-generation drugs are being applied to develop safer PPAR-targeted therapies. The finding that rosiglitazone may increase risk for cardiovascular events has led to regulatory guidelines requiring demonstration of cardiovascular safety in appropriate outcome trials for new type 2 diabetes mellitus drugs. The emerging data on the possibly increased risk of bladder cancer with pioglitazone may prompt the need for post-approval safety studies for new drugs. Since PPAR-α and -γ affect key cardiometabolic risk factors (diabetic dyslipidemia, insulin resistance, hyperglycemia, and inflammation) in a complementary fashion, combining their benefits has emerged as a particularly attractive option. New PPAR-targeted therapies that balance the relative potency and/or activity toward PPAR-α and -γ have shown promise in retaining efficacy while reducing potential side effects.

Genetics of Lipid and Lipoprotein Disorders and Traits.

Plasma lipids, namely cholesterol and triglyceride, and lipoproteins, such as low-density lipoprotein (LDL) and high-density lipoprotein, serve numerous physiological roles. Perturbed levels of these traits underlie monogenic dyslipidemias, a diverse group of multisystem disorders. We are on the verge of having a relatively complete picture of the human dyslipidemias and their components. Recent advances in genetics of plasma lipids and lipoproteins include the following: (1) expanding the range of genes causing monogenic dyslipidemias, particularly elevated LDL cholesterol; (2) appreciating the role of polygenic effects in such traits as familial hypercholesterolemia and combined hyperlipidemia; (3) accumulating a list of common variants that determine plasma lipids and lipoproteins; (4) applying exome sequencing to identify collections of rare variants determining plasma lipids and lipoproteins that via Mendelian randomization have also implicated gene products such as NPC1L1 , APOC3 , LDLR , APOA5 , and ANGPTL4 as causal for atherosclerotic cardiovascular disease; and (5) using naturally occurring genetic variation to identify new drug targets, including inhibitors of apolipoprotein (apo) C-III, apo(a), ANGPTL3, and ANGPTL4. Here, we compile this disparate range of data linking human genetic variation to plasma lipids and lipoproteins, providing a "one stop shop" for the interested reader.

Background: Evidence from controlled trials encourages the intake of dietary pulses (beans, chickpeas, lentils and peas) as a method of improving dyslipidemia, but heart health guidelines have stopped short of ascribing specific benefits to this type of intervention or have graded the beneficial evidence as low. We conducted a systematic review and meta-analysis of randomized controlled trials (RCTs) to assess the effect of dietary pulse intake on established therapeutic lipid targets for cardiovascular risk reduction. Methods: We searched electronic databases and bibliographies of selected trials for relevant articles published through Feb. 5, 2014. We included RCTs of at least 3 weeks’ duration that compared a diet emphasizing dietary pulse intake with an isocaloric diet that did not include dietary pulses. The lipid targets investigated were low-density lipoprotein (LDL) cholesterol, apolipoprotein B and non–high-density lipoprotein (non-HDL) cholesterol. We pooled data using a random-effects model. Results: We identified 26 RCTs (n = 1037) that satisfied the inclusion criteria. Diets emphasizing dietary pulse intake at a median dose of 130 g/d (about 1 serving daily) significantly lowered LDL cholesterol levels compared with the control diets (mean difference −0.17 mmol/L, 95% confidence interval −0.25 to −0.09 mmol/L). Treatment effects on apolipoprotein B and non-HDL cholesterol were not observed. Interpretation: Our findings suggest that dietary pulse intake significantly reduces LDL cholesterol levels. Trials of longer duration and higher quality are needed to verify these results. Trial registration: ClinicalTrials.gov, no. NCT01594567. PMID:24710915

Hepatic AMP Kinase as a Potential Target for Treating Nonalcoholic Fatty Liver Disease: Evidence from Studies of Natural Products.

2018-01-01

Nonalcoholic fatty liver disease (NAFLD), the most common chronic liver disease, is the leading cause of cryptogenic cirrhosis and has consistently been implicated in related metabolic disorders, such as dyslipidemia and type 2 diabetes (T2D). However, the pathogenesis of NAFLD remains to be elucidated, and no established therapeutic regimens for treating NAFLD exist. Adenosine monophosphate (AMP)-activated protein kinase (AMPK), the main cellular energy sensor, has been implicated as a key regulator of hepatic lipid and glucose metabolism. Recently, emerging evidence indicates that many plant-derived natural products are capable of ameliorating NAFLD by targeting AMPK. The published literature in PubMed relating to this topic was searched through June 2016. Significant advances have been made with respect to understanding the protective effects of plant-derived natural products against NAFLD. A variety of natural products, including alkaloids (berberine, demethyleneberberine, nicotine, caffeine, etc.), polyphenols (resveratrol, puerarin, curcumin, caffeic acid, etc.) and other compounds (β- caryophyllene, gastrodin, compound K, betulinic acid, etc.), have demonstrated promising results in preclinical studies. Mechanistic studies of these compounds have focused on their activation of AMPK and its downstream effectors involved in lipid metabolism. The findings of this review confirm that plant-derived natural products capable of activating the AMPK signaling pathway are potential therapeutic agents for NAFLD.

Allium ampeloprasum (AA) is a medicinal plant which is used in Iranian traditional medicine to treat or prevent different diseases. The aim of this study is to investigate the effect of AA extract on oxidative stress and dyslipidemia in diabetic rats induced by alloxan. In this experimental study, 60 male Wistar rats weighing 200-250gr were randomly divided to five groups of 12 each including healthy control (group I), diabetic control (group II), metformin-treated diabetic positive control (group III) and two groups treated with doses 400 (group IV) and 800 (groupV) mg/kg/BW of AA extracts. Diabetes mellitus was experimentally induced by injection of two doses of alloxan-120 and 65mg/kg-within two consecutive days. Alloxan-induced diabetes caused significant increase in serum glucose, triglyceride (TG), total cholesterol (TC), low density lipoprotein (LDL), very low density lipoprotein (VLDL) and high density lipoprotein (HDL) levels in group II (p<0.05). Furthermore, serum malondialdehyde (MDA) levels increased significantly and liver catalase activity decreased significantly in the 2nd group compared to 1st control; respectively p=0.0001 and p=0.009. In the group IV has seen a significant decrease in serum TG (p=0.01), TC (p=0.0001), VLDL (p=0.01), and MDA (p=0.0001) levels and significant increase in the liver and kidney catalase activities of the rats compared to the group II; respectively p=0.0001 and p=0.0001. In Conclusion our results highlight potentially relevant health beneficial effects of AA extract which exerts hypoglycemic, hypolipidemic, and anti-oxidative stress effects in rats with alloxan-induced diabetes. Therefore, it may be considered as useful dietary supplements in diabetic patients. Copyright © 2016 Elsevier Masson SAS. All rights reserved.

The recently observed association between the APOC3-related rs10892151 polymorphism and serum triglyceride levels has prompted us the possibility to explore whether this genetic variant may play a major role in human immunodeficiency virus (HIV)/antiretroviral therapy-induced dyslipidemia. We determined the rs10892151 genotype distribution and serum apolipoprotein (apo) C-III concentration in a group of HIV-infected patients (n = 208) and in a group of age and sex-matched healthy volunteers (n = 200). Circulating lipid and lipoprotein levels were followed for 12 months after antiretroviral treatment initiation in the HIV-infected group. There were no significant variations in the frequency of the A allele between the healthy and HIV-infected groups (7.5 vs. 8.6%, respectively; p = 0.7); additionally, the A allele was not related to serum apo C-III concentration. However, among patients receiving protease inhibitor (PI) treatment, carriers of the A allele had significantly increased serum triglyceride (5.76 ± 2.54 mmol/L) and total cholesterol (6.63 ± 2.85 mmol/L) concentrations together with depressed levels of HDL-cholesterol (0.75 ± 0.3 mmol/L) when compared with patients not carrying the allele (2.43 ± 1.32, 5.2 ± 2.17 and 1.24 ± 0.4 mmol/L, respectively) at the end of the study. This effect was only evident for HDL-cholesterol concentration when patients were treated with non-nucleoside reverse transcriptase inhibitors (1.05 ± 0.4 vs. 1.28 ± 0.4 mmol/L). The A allelic variant of the rs10892151 polymorphism is not associated with serum apo C-III concentration, but predisposes HIV-infected patients to less favorable lipid profile, particularly in those patients treated with PIs.

Garlic oil nanoemulsion was formulated using ultrasonic emulsification and the optimized garlic oil nanoemulsion ratio (1:2) of oil: surfactant showed spherical, with tiny droplet size 24.9 ± 1.11 nm. It was observed that the prepared nanoemulsion has the zeta potential of -42.63 ± 1.58 mV and a low polydispersity index of 0.2 ± 0.09 with excellent stability. The formulation was subjected to in vivo acute and sub-acute toxicity. In acute toxicity study, single oral administration of 18.63 ml of garlic oil nanoemulsion/kg resulted in immediate mortality. However, garlic oil nanoemulsion (0.46 ml/kg) and tween 80 (0.5 ml/kg) administered rats did not exhibit any toxicity and showed no changes in hematological and histological parameters. Further, both preventive and curative studies of garlic oil nanoemulsion were evaluated in high-fat diet fed dyslipidemic Wistar rats. Garlic oil nanoemulsion administered groups showed a significant effect in reducing the levels of lipid profiles (p < 0.001) compared to atorvastatin and garlic oil. Evaluation of lipid deposits in hepatic tissues was analyzed by Oil Red O staining, which revealed that garlic oil nanoemulsion administered rats markedly reduced the fat depots. Our findings suggest that garlic oil nano-emulsified form reduced toxicity and improved efficacy in preventing and treating dyslipidemia. Copyright © 2017 Elsevier Ltd. All rights reserved.

Comprehensive management of diabetes should include management of its comorbid conditions, especially cardiovascular complications, which are the leading cause of morbidity and mortality among patients with diabetes. Dyslipidemia is a comorbid condition of diabetes and a risk factor for cardiovascular complications. Therefore, lipid level management is a key of managing patients with diabetes successfully. However, it is not clear that how well dyslipidemia is managed in patients with diabetes in local Chinese health-care communities. This study aimed to assess how well low-density lipoprotein cholesterol (LDL-C) was managed in Nanjing community hospitals, China. We reviewed clinical records of 7364 diabetic patients who were treated in eleven community hospitals in Nanjing from October 2005 to October 2014. Information regarding LDL-C level, cardiovascular risk factors, and use of lipid-lowering agents were collected. In patients without history of cardiovascular disease (CVD), 92.1% had one or more CVD risk factors, and the most common CVD risk factor was dyslipidemia. The overall average LDL-C level was 2.80 ± 0.88 mmol/L, which was 2.62 ± 0.90 mmol/L and 2.82 ± 0.87 mmol/L in patients with and without CVD history respectively. Only 38% of all patients met the target goal and 37.3% of patients who took lipid-lowering agents met target goal. Overall, 24.5% of all patients were on lipid-lowering medication, and 36.3% of patients with a CVD history and 20.9% of patients without CVD history took statins for LDL-C management. The mean statin dosage was 13.9 ± 8.9 mg. Only a small portion of patients achieved target LDL-C level, and the rate of using statins to control LDL-C was low. Managing LDL-C with statins in patients with diabetes should be promoted, especially in patients without a CVD history and with one or more CVD risk factors.

Recent evidences have suggested the beneficial cardiovascular effects of some plants belonging to the genus Allium. The present study is an attempt to investigate the effects of hydroalcoholic extract of Allium elburzense bulb on dexamethasone-induced dyslipidemia in rats. Total phenolic content of A. elburzense bulb hydroalcoholic extract was determined using Folin-Ciocalteu method. Thirty-six male Wistar albino rats in 6 groups were studied. Group 1 (dyslipidemic control) received dexamethasone (10 mg/kg/day, s.c.) for 7 days, groups 2-4 (treated) received dexamethasone and simultaneously treated orally with 100, 200, or 400 mg/kg of A. elburzense extract, group 5 (normal control) received a single daily injection of normal saline (1 mL/kg, s.c.) and the vehicle orally, and group 6 (reference) received dexamethasone and atorvastatin (40 mg/kg) orally. At the end of experiment, blood glucose, lipid profile, and malondialdehyde (MDA) levels were assessed in serum samples. Livers were processed for histopathological examination. Total phenolic content of A. elburzense extract was estimated to be 33.52 ± 1.3% mg gallic acid equivalent/g of the dried plant extract. The plant extract significantly reduced serum blood glucose, triglyceride, total cholesterol, low-density lipoprotein-cholesterol, and MDA levels and increased the high density lipoprotein-cholesterol level and also improved liver steatosis compared to the dyslipidemic control group. These results suggest the hydroalcoholic extract of A. elburzense bulb has anti-dyslipidemic, anti-hyperglycemic, and antioxidant effects on rats receiving high doses of dexamethasone. PMID:29387108

It is widely known that salt is an accelerating factor for the progression of metabolic syndrome and causes cardiovascular diseases, most likely due to its pro-oxidant properties. We hypothesized that excessive salt intake also facilitates the development of nonalcoholic steatohepatitis (NASH), which is frequently associated with metabolic syndrome. We examined the exacerbating effect of high-salt diet on high-fat diet-induced liver injury in a susceptible model to oxidative stress, apoE knockout and lectin-like oxidized low-density lipoprotein receptor-1 (LOX-1) transgenic mice. High-salt diet led to NASH in high-fat diet-fed LOX-1 transgenic/apoE knockout mice without affecting high-fat diet-induced dyslipidemia or hepatic triglyceride accumulation. Additionally, a high-salt and high-fat diet stimulated oxidative stress production and inflammatory reaction to a greater extent than did a high-fat diet in the liver of LOX-1 transgenic/apoE knockout mice. We demonstrated that high-salt diet exacerbated NASH in high-fat diet-fed LOX-1 transgenic /apoE knockout mice and that this effect was associated with the stimulation of oxidative and inflammatory processes; this is the first study to suggest the important role of excessive salt intake in the development of NASH.

Design of ligand-targeted nanoparticles for enhanced cancer targeting

Stefanick, Jared F.

Ligand-targeted nanoparticles are increasingly used as drug delivery vehicles for cancer therapy, yet have not consistently produced successful clinical outcomes. Although these inconsistencies may arise from differences in disease models and target receptors, nanoparticle design parameters can significantly influence therapeutic efficacy. By employing a multifaceted synthetic strategy to prepare peptide-targeted nanoparticles with high purity, reproducibility, and precisely controlled stoichiometry of functionalities, this work evaluates the roles of polyethylene glycol (PEG) coating, ethylene glycol (EG) peptide-linker length, peptide hydrophilicity, peptide density, and nanoparticle size on tumor targeting in a systematic manner. These parameters were analyzed in multiple disease models by targeting human epidermal growth factor receptor 2 (HER2) in breast cancer and very late antigen-4 (VLA-4) in multiple myeloma to demonstrate the widespread applicability of this approach. By increasing the hydrophilicity of the targeting peptide sequence and simultaneously optimizing the EG peptide-linker length, the in vitro cellular uptake of targeted liposomes was significantly enhanced. Specifically, including a short oligolysine chain adjacent to the targeting peptide sequence effectively increased cellular uptake ~80-fold using an EG6 peptide-linker compared to ~10-fold using an EG45 linker. In vivo, targeted liposomes prepared in a traditional manner lacking the oligolysine chain demonstrated similar biodistribution and tumor uptake to non-targeted liposomes. However, by including the oligolysine chain, targeted liposomes using an EG45 linker significantly improved tumor uptake ~8-fold over non-targeted liposomes, while the use of an EG6 linker decreased tumor accumulation and uptake, owing to differences in cellular uptake kinetics, clearance mechanisms, and binding site barrier effects. To further improve tumor targeting and enhance the selectivity of targeted

There are at least two good reasons for the on-going interest in drug–target interactions: first, drug-effects can only be fully understood by considering a complex network of interactions to multiple targets (so-called off-target effects) including metabolic and signaling pathways; second, it is crucial to consider drug-target-pathway relations for the identification of novel targets for drug development. To address this on-going need, we have developed a web-based data warehouse named SuperTarget, which integrates drug-related information associated with medical indications, adverse drug effects, drug metabolism, pathways and Gene Ontology (GO) terms for target proteins. At present, the updated database contains >6000 target proteins, which are annotated with >330 000 relations to 196 000 compounds (including approved drugs); the vast majority of interactions include binding affinities and pointers to the respective literature sources. The user interface provides tools for drug screening and target similarity inclusion. A query interface enables the user to pose complex queries, for example, to find drugs that target a certain pathway, interacting drugs that are metabolized by the same cytochrome P450 or drugs that target proteins within a certain affinity range. SuperTarget is available at http://bioinformatics.charite.de/supertarget. PMID:22067455

Attentional Control via Parallel Target-Templates in Dual-Target Search

Simultaneous search for two targets has been shown to be slower and less accurate than independent searches for the same two targets. Recent research suggests this ‘dual-target cost’ may be attributable to a limit in the number of target-templates than can guide search at any one time. The current study investigated this possibility by comparing behavioural responses during single- and dual-target searches for targets defined by their orientation. The results revealed an increase in reaction times for dual- compared to single-target searches that was largely independent of the number of items in the display. Response accuracy also decreased on dual- compared to single-target searches: dual-target accuracy was higher than predicted by a model restricting search guidance to a single target-template and lower than predicted by a model simulating two independent single-target searches. These results are consistent with a parallel model of dual-target search in which attentional control is exerted by more than one target-template at a time. The requirement to maintain two target-templates simultaneously, however, appears to impose a reduction in the specificity of the memory representation that guides search for each target.

Lipid-lowering therapy: who can benefit?

Cardiovascular disease (CVD) is the leading cause of death in the US. Despite the decline in CVD-associated mortality rates in recent years, coronary heart disease (CHD) still causes one in every six deaths in this country. Because most CHD risk factors are modifiable (eg, smoking, hypertension, obesity, onset of type 2 diabetes, and dyslipidemia), cardiovascular risk can be reduced by timely and appropriate interventions, such as smoking cessation, diet and lifestyle changes, and lipid-modifying therapy. Dyslipidemia, manifested by elevated low-density lipoprotein cholesterol (LDL-C), is central to the development and progression of atherosclerosis, which can be silent for decades before triggering a first major cardiovascular event. Consequently, dyslipidemia has become a primary target of intervention in strategies for the prevention of cardiovascular events. The guidelines of the Adult Treatment Panel (ATP) III, updated in 2004, recommend therapeutic lifestyle changes and the use of lipid-lowering medications, such as statins, to achieve specific LDL-C goals based on a person's global cardiovascular risk. For high-risk individuals, such as patients with CHD and diabetic patients without CHD, an LDL-C target of < 100 mg/dL is recommended, and statin therapy should be considered to help patients achieve this goal. If correctly dosed in appropriate patients, currently approved statins are generally safe and provide significant cardiovascular benefits in diverse populations, including women, the elderly, and patients with diabetes. A recent primary prevention trial also showed that statins benefit individuals traditionally not considered at high risk of CHD, such as those with no hyperlipidemia but elevated C-reactive protein. Additional evidence suggests that statins may halt or slow atherosclerotic disease progression. Recent evidence confirms the pivotal role of statins in primary and secondary prevention.
