Postprandial serum triglyceride concentrations have recently been identified as a major, independent risk factor for future cardiovascular events. As a result, postprandial hyperlipidemia has emerged as a potential therapeutic target. The purpose of this study was two-fold. Firstly, to describe and characterize a standardized model of postprandial hyperlipidemia in multiple rodent species; and secondly, apply these rodent models to the evaluation of a novel class of pharmacologic agent; acyl CoA:diacylglycerol acyltransferase (DGAT) 1 inhibitors. Serum triglycerides were measured before and for 4h after oral administration of a standardized volume of corn oil, to fasted C57BL/6, ob/ob, apoE(-/-) and CD-1 mice; Sprague-Dawley and JCR/LA-cp rats; and normolipidemic and hyperlipidemic hamsters. Intragastric administration of corn oil increased serum triglycerides in all animals evaluated, however the magnitude and time-course of the postprandial triglyceride excursion varied. The potent and selective DGAT-1 inhibitor A-922500 (0.03, 0.3 and 3 mg/kg, p.o.), dose-dependently attenuated the maximal postprandial rise in serum triglyceride concentrations in all species tested. At the highest dose of DGAT-1 inhibitor, the postprandial triglyceride response was abolished. This study provides a comprehensive characterization of the time-course of postprandial hyperlipidemia in rodents. In addition, the ability of DGAT-1 inhibitors to attenuate postprandial hyperlipidemia in multiple rodent models, including those that feature insulin resistance, is documented. Exaggerated postprandial hyperlipidemia is inherent to insulin-resistant states in humans and contributes to the substantially elevated cardiovascular risk observed in these patients. Therefore, by attenuating postprandial hyperlipidemia, DGAT-1 inhibition may represent a novel therapeutic approach to reduce cardiovascular risk. Copyright 2010 Elsevier B.V. All rights reserved.

Multiple genetic loci associated with lipid levels have been identified predominantly in Europeans, and the issue of to what extent these genetic loci can predict blood lipid levels increases over time and the incidence of future hyperlipidemia remains largely unknown. We conducted a meta-analysis of genome-wide association studies of lipid levels in 8344 subjects followed by replication studies including 14 739 additional individuals. We replicated 17 previously reported loci. We also newly identified 3 Chinese-specific variants in previous regions (HLA-C, LIPG, and LDLR) with genome-wide significance. Almost all the variants contributed to lipid levels change and incident hyperlipidemia >8.1-year follow-up among 6428 individuals of a prospective cohort study. The strongest associations for lipid levels change were detected at LPL, TRIB1, APOA1-C3-A4-A5, LIPC, CETP, and LDLR (P range from 4.84×10(-4) to 4.62×10(-18)), whereas LPL, TRIB1, ABCA1, APOA1-C3-A4-A5, CETP, and APOE displayed significant strongest associations for incident hyperlipidemia (P range from 1.20×10(-3) to 4.67×10(-16)). The 4 lipids genetic risk scores were independently associated with linear increases in their corresponding lipid levels and risk of incident hyperlipidemia. A C-statistics analysis showed significant improvement in the prediction of incident hyperlipidemia on top of traditional risk factors including the baseline lipid levels. These findings identified some evidence for allelic heterogeneity in Chinese when compared with Europeans in relation to lipid associations. The individual variants and those cumulative effects were independent risk factors for lipids increase and incident hyperlipidemia. © 2015 American Heart Association, Inc.

OBJECTIVE: Community health centers (HCs) provide care for millions of medically underserved Americans with disproportionate burdens of hypertension and hyperlipidemia. For both conditions, treatment guidelines recently became more stringent and quality improvement (QI) efforts have intensified. We assessed hypertension and hyperlipidemia management in HCs during this time of guideline revision and increased QI efforts. DESIGN: Cross-sectional chart review. SETTING AND PARTICIPANTS: Eleven Midwestern HCs for 2000 and 9 for 2002 provided audit data from 2,976 randomly chosen patients with hypertension and/or hyperlipidemia. MEASUREMENT: Joint National Committee on Prevention, Detection, Evaluation and Treatment of High Blood Pressure (JNC VI/VII) and National Cholesterol Education Program Adult Treatment Panel (NCEP-ATP III) guidelines were used to assess management of these conditions. RESULTS: Hypertension (2000, N=808; 2002, N=692) and hyperlipidemia (2000, N=774; 2002, N=702) outcomes improved for specific clinical subgroups. Hypertensive patients with 1 or more cardiovascular risk factors demonstrated significant improvement (34% vs. 45% controlled at <140/90 mm Hg, p=0.02). Hypertension control for persons with diabetes, renal failure and heart failure increased (16% vs. 28% controlled at <130/85 mm Hg, p=0.006). LDL control increased significantly for patients with 2 or more risk factors (39% vs. 58% controlled at <130 mg/dl, p=0.008). Other clinical subgroups showed trends toward better control, although there was insufficient power to detect significant differences for these groups. CONCLUSION: Hypertension and hyperlipidemia outcomes improved for some risk groups; however, ongoing QI is necessary.

Vascular endothelial growth facto receptor-tyrosine kinase inhibitors (VEGFR-TKIs) are widely used for metastatic renal cell carcinoma (mRCC). The aim of this study was to investigate the association between the response to VEGFR-TKIs and hyperlipidemia and hypothyroidism. Clinical data on 155 patients with mRCC treated with VEGFR-TKIs at the Cancer Hospital of Chinese Academy of Medical Sciences from 2006 to 2014 were retrospectively analyzed. All patients received first-line TKI therapy. Survival analysis was performed with a significance level of 0.05 using a Kaplan-Meier curve. The χ(2) test was used for the intergroup comparison. The Cox regression model was used for the analysis of multiple factors affecting survival. The median survival for the whole group (n = 155) was 36.2 months. A total of 57 patients (36.8 percent) developed hypothyroidism and 85 patients (54.9 percent) experienced hyperlipidemia. The response rate (RR) and median progression-free survival (mPFS) for patients with normal thyroid function were 32.7 percent and 9.1 months, respectively, 54.5 percent and 13.7 months with grade I hypothyroidism, 70.8 percent and 23.8 months with grade II hypothyroidism (P values of 0.001 and 0.017, respectively). The RR and mPFS for patients with normal blood lipids were 23.9 percent and 8.0 months, respectively, 54.0 percent and 12.9 months with grade I hyperlipidemia, 60.7 percent and 14.0 months with grade II hyperlipidemia, and 100.0 percent and 22.2 months with grade III hyperlipidemia. Significant differences in the RR and mPFS were seen between groups (the P values were 0.000 and 0.005, respectively). Hypothyroidism or hyperlipidemia may be effective predictive factors for response to treatment with VEGFR-TKIs in mRCC patients. Large-sample studies are warranted to further prove these results. © 2016 John Wiley & Sons Australia, Ltd.

To evaluate the anti-hyperlipidemic activity of lemongrass oil against in dexamethasone induced hyperlipidemia in rats. Administration of dexamethasone was given at 10 mg/kg, sc. to the adult rats for 8 d induces hyperlipidemia characterized by marked increase in serum cholesterol and triglyceride levels along with increase in atherogenic index. Lemongrass oil (100 and 200 mg/kg, po.) treatment has showed significant inhibition against dexamethasone hyperlipidemia by maintaining the serum levels of cholesterol, triglycerides and atherogenic index near to the normal levels and the antihyperlipidemic effect of the lemongross oil was comparable with atorvastatin 10 mg/kg, po. The possible mechanism may be associated with decrease in lecithin cholesterol acetyl transferase (LCAT) activity. These results suggested that Lemon gross oil possess significant anti-hyperlipidemic activity. Copyright © 2011 Hainan Medical College. Published by Elsevier B.V. All rights reserved.

Coronary heart disease (CHD) is prevalent and often related to an unhealthy diet and hyperlipidemia. The diagnosis of hyperlipidemia should be carefully made, using more than one measurement in the manner described. An assessment of risks allows one to decide whom to treat. Patients with CHD should be treated aggressively but it is less clear how aggressive to be with patients without CHD. Diet and exercise recommendations are appropriate for almost all patients. For those for whom the benefit is greater than the potential risks, statins are first-line drug therapy and they appear to have beneficial effects aside from their lipid-lowering properties.

Objective Hyperlipidemia guidelines do not currently identify inflammatory arthritis (IA) as a cardiovascular disease (CVD) risk factor. We compared hyperlipidemia treatment of individuals with and without IA (rheumatoid arthritis, psoriatic arthritis, or ankylosing spondylitis) in a large national cohort. Methods Participants from the REasons for Geographic And Racial Differences in Stroke (REGARDS) study were classified as having IA (without diabetes or hypertension); diabetes (but no IA); hypertension (but no diabetes or IA); or no IA, diabetes, or hypertension. Multivariable logistic regression models examined the odds of medical treatment among those with hyperlipidemia. Results Thirty-nine participants had IA, 5423 had diabetes, 7534 had hypertension, and 5288 had no diabetes, hypertension, or IA. The fully adjusted odds of treatment were similar between participants with IA and those without IA, hypertension, or diabetes. Participants with diabetes and no IA and participants with hypertension and no IA were twice as likely to be treated for hyperlipidemia as those without IA, diabetes, or hypertension. Conclusion Despite their higher CVD risk, patients with IA were as likely to be treated for hyperlipidemia as those without diabetes, hypertension, or IA. Lipid guidelines should identify IA as a CVD risk factor to improve CVD risk optimization in IA.

Oral retinoids are commonly prescribed for many dermatological conditions and may induce hyperlipidemia. We document the case of a 35-year-old man taking acitretin for congenital lamellar ichthyosis associated with a homozygous deleterious mutation in NIPAL4 who developed retinoid-induced hyperlipidemia that responded dramatically to a whole-food plant-based (WFPB) diet. On presentation, his diet consisted of chicken, fish, low fat meats and dairy, grains, and some fruits and vegetables. He then adopted a WFPB diet without making changes to his medications. His serum lipid levels dropped and his exercise capacity improved. Five months later, after discontinuing the plant-based diet and returning to his baseline diet, his hyperlipidemia returned and persisted despite adjustments to his medications. After a year and a half, the patient again adopted a plant-based diet and his lipid levels fell sharply again. A WFPB diet helped improve and control serum lipid levels in a patient with retinoid-induced hyperlipidemia. Future interventions should focus on ways to help patients successfully adopt and maintain a WFPB diet, as increased adherence to a healthy lifestyle is associated with greater health benefits.

To determine the role of atorvastatin in management of tinnitus in patients with hyperlipidemia. Quasi-experimental study. ENT Department, Combined Military Hospital, Rawalpindi, from July 2011 to August 2012. Ninety eight patients of tinnitus with sensorineural hearing loss having hyperlipidemia were included in the study. Their pre-therapy serum cholesterols were measured, and tinnitus scores were recorded on a 'Tinnitus handicap questionnaire'. They were administered tablet atorvastatin 40 mg once daily with low fat diet for 8 months. After 8 months of therapy, patients were purposefully divided into responsive and unresponsive group depending on serum cholesterol levels. Post therapy serum cholesterol levels and tinnitus scores were also recorded after 8 months and compared with pre-therapy records. Serum cholesterol came to within normal limits in 51 (52%) patients (responsive group), while it remained high in 47 (48%) patients (unresponsive group). Improvement in tinnitus score in the responsive group was seen in 36 (70.5%) patients and in 2 (4.2%) patients of the unresponsive group. Improvement in tinnitus scores was compared in the two groups using Fisher's exact test and were found to be statistically better in the responsive group (p < 0.001). Tinnitus, in patients having hyperlipidemia, can be successfully dealt with by treating hyperlipidemia with lipid lowering agent atorvastatin.

Bezafibrate (BZF) is effective in the treatment of hypertriglyceridemia in human patients, but there are no data on its use in dogs. To assess the safety of BZF in hyperlipidemic dogs and its efficacy in decreasing serum triglyceride (TG) and cholesterol (CHO) concentrations. Forty-six dogs, 26 females and 20 males, mean (±SD) age of 9 (±3) years, with TG ≥150 mg/dL (33 dogs also were hypercholesterolemic [>300 mg/dL]). Prospective, uncontrolled clinical trial. Dogs were treated with bezafibrate once daily, using 200 mg tablets at a dosage of 4-10 mg/kg (depending on body weight). Serum TG and CHO concentrations and alanine aminotransferase (ALT) and creatine kinase (CK) activity before and after 30 days of treatment were compared. Sixteen dogs (34.8%) had primary hyperlipidemia, and 30 dogs (65.2%) had secondary hyperlipidemia (including spontaneous hyperadrenocorticism [41.3%, n = 19/46], chronic treatment with glucocorticoids [10.8%, n = 5/46], and hypothyroidism [15.2%, n = 7/46]). After 30 days, serum TG concentration normalized (<150 mg/dL) in 42 dogs (91.3%) and CHO concentration normalized (<270 mg/dL) in 22 of 33 dogs (66.7%). There was no difference in baseline TG concentration between the primary and secondary hyperlipidemia subgroups, but the decrease in TG concentration after treatment was greater in the primary hyperlipidemia subgroup. No adverse effects were observed, but ALT activity decreased significantly after 30 days of treatment. Over 30 days, BZF was safe and effective in treatment of primary and secondary hyperlipidemia in dogs. Copyright © 2017 The Authors.

Hypertension and hyperlipidemia represent two major risk factors for atherosclerotic cardiovascular disease. Mobile health or mHealth is defined as the use of mobile phone and wireless technologies to support the achievement of health objectives. Management of hypertension, and to some extent hyperlipidemia, has often employed mHealth interventions given lower cost and greater patient engagement compared to traditional methods. These interventions include the use of text messaging, wireless devices, and mobile phone applications. This review considers recent studies evaluating the effectiveness of mHealth interventions in the management of hypertension and hyperlipidemia. Numerous studies have evaluated the role of mHealth interventions in the management of hypertension, while very few have evaluated their role in hyperlipidemia. Text messaging has been used most frequently. However, the trend is shifting towards the use of mobile phone applications and wireless devices. Interventions in developing countries have been modified for greater applicability to local settings. mHealth interventions were found to be frequently effective. However, studies comparing the relative efficacy of various mHealth strategies are scarce. Long-term cardiovascular outcomes data and analyses relating to cost effectiveness are also lacking. mHealth interventions may be effective in improving hypertension management. More studies are needed to evaluate the role of mHealth strategies in hyperlipidemia management, particularly in identifying high-risk individuals and improving medication adherence. Studies assessing the long-term impact of these interventions, comparing different interventions and analyzing their relative cost effectiveness, are also needed. Following recently published guidelines on reporting results of mHealth interventions will provide a more meaningful context for interpreting these promising early studies.

Hyperlipidemia is one of the major risk factors for atherosclerosis and ischemic heart disease. Chromium (Cr) mineral is playing a crucial role in glucose and lipid homeostasis. The aim of this study was to evaluate the protective effects of combined chromium picolinate (CrPic) and atorvastatin treatment against hyperlipidemia-induced cardiac injury. Seventy-five male albino rats were divided into five groups (15 rats each). Hyperlipidemia was induced by intraperitoneal injection of a single dose of Triton X-100 (300 mg/kg body weight (b.w) (group ІІ). Treatment of hyperlipidemic rats was induced by daily administration of CrPic at a dose of 200 μg/kg b.w/day (group ІІІ), atorvastatin at a dose of 10 mg/kg/day (group IV), and combined treatment with both (group V) by gavage for 7 days. At the end of experiment, serum and heart tissues were obtained. Hyperlipidemia was confirmed by histopathology of heart tissues, marked serum dyslipidemia, increased atherogenic indices, and values of ischemia-modified albumin. In addition to increased values of proprotein convertase subtilisin/kexin type 9, activity of 3-hydroxy-3-methylglutaryl coenzyme A reductase enzyme and high relative expression levels of pentraxin-3 were observed. However, paraoxonase-1 activity was markedly decreased in the hyperlipidemic group. Significant improvement in all assessed parameters was observed in the rat group treated with both CrPic and atorvastatin. It can be concluded that combined CrPic and atorvastatin treatments had synergistic cardioprotective effects against hyperlipidemia which may be through modulating atherosclerosis as well as cardiac and aortic damage and/or activation of anti-inflammatory and anti-oxidant pathways, thus reversing endothelial dysfunction.

Hyperlipidemia, obesity, hypertension, and diabetes are the most important risk factors for cardiovascular diseases. The aim of this systematic review article is to introduce the medicinal plants that exert significant clinical effects on hypertension, hyperlipidemia, obesity, and diabetes. In this review article, the international research databases including MEDLINE, Google scholar, EBSCO, Academic Search, Web of Science, SciVerse, Scopus (SCOPUS), EBSCO, Academic Search, Cochrane, Central Register of Controlled Trials (CENTRAL) and a Chinese database (China Network Knowledge Infrastructure [CNKI]) were searched using the key words hyperlipidemia, hypertension, diabetes, herbal, obesity, and phytomedicine, matched by MESH, from their respective inceptions up to March, 2016. The plants that were effective on one, two, three, or all of four diseases were determined. The doses, side effects, the most important pharmaceutically effective compounds, the used organs, and important points regarding usage were separately recorded. Also known clinically significant interactions were presented. 1023 articles were found to be about medicinal plants and hypertension, 1912 articles about medicinal plants and hyperlipidemia, 810 articles about medicinal plants and obesity, 1174 articles about medicinal plants and diabetes. Of 144 plants included in the analysis, 83 were found to be effective on hyperlipidemia, 100 on hypertension, 66 on obesity, and 72 on diabetes. 43 plants were found to be effective on two diseases, 14 on three diseases, and 34 on all four diseases. Three plants (Tomato, Cranberry and Pomegranate), in food and therapeutic doses, were found to be used to treat cardiovascular diseases especially in pre-eclampsia and hyperlipidemia in pregnancy. Regarding the findings of this study, we can argue that the medicinal plants, other than monotherapy, can be used as poly-therapy, to treat cardiovascular diseases.

To explore the effect of Linguizhugan decoction on hyperlipidemia rats with caloric restriction. The hyperlipidemia model of rat was induced by high fat diet for 8 weeks. After the model was established, 26 rats were randomly divided into 4 groups: the control group (n = 6), the model group (n = 6), the intermittent fasting (IF) group (n = 8), and the IF and herbal medicine (IFH) group (n = 6). IF group was applied intermittent fasting every other day. The IFH group was given Linguizhugan decoction every day and intermittent fasting every other day. Blood samples were taken at the end of 16 weeks, and serum ghrelin and lipid was tested. Serum ghrelin in the IF group significantly increased (P < 0.01). Serum ghrelin in IFH group was lower than the IF group (P < 0.05), but higher than the model group (P < 0.01). Linguizhugan decoction may play a part in regulation of energy and appetite in hyperlipidemia rats with IF.

Hyperlipidemia, hyperlipemia, and hepatic lipidosis in American miniature horses: 23 cases (1990-1994).

The medical records of 23 American Miniature Horses with hyperlipidemia, hyperlipemia, or hepatic lipidosis were reviewed. The most common clinical signs were anorexia and lethargy. The mean duration of clinical signs was 2.4 days. A primary disease was identified in 19 cases. Enterocolitis was the most common primary disease (n = 10). Intentional feed restriction, as part of treatment for colic, resulted in hyperlipemia in 2 horses and hyperlipidemia in 1. Four horses had primary hyperlipemia, 3 of which had signs of hepatoencephalopathy secondary to hepatic lipidosis. Dextrose, heparin, and insulin were the most common treatments. The overall survival was 61% (14/23). All horses with peak serum triglyceride concentrations > 1,200 mg/dl died or were euthanatized, whereas all but 1 with peak serum triglyceride concentrations < 1,200 mg/dl survived. These findings suggest that when American Miniature Horses, like other ponies and donkeys, are in a negative energy balance, they can rapidly develop hyperlipidemia or hyperlipemia. Early detection and treatment may improve survival.

Vitale, Christina L; Olby, Natasha J

Hypothyroidism has been associated with a variety of neurologic signs, but the mechanism for this association is not completely understood. Hypothyroidism also is associated with hyperlipidemia that predisposes to atherosclerosis, increased blood viscosity, and thromboembolic events. The objective is to characterize neurologic signs potentially associated with hyperlipidemia and atherosclerosis in canine hypothyroidism. This study used dogs referred to North Carolina State University Veterinary Teaching Hospital for evaluation of neurologic signs. A retrospective study was conducted in which medical records of dogs with neurologic signs and a diagnosis of hypothyroidism and hyperlipidemia were reviewed. Details of the history, presenting signs, results of routine blood tests, thyroid tests, cerebrospinal fluid (CSF) analysis and diagnostic imaging, and response to therapy were compiled. Three Labrador Retrievers and one Labrador Retriever cross fit the inclusion criteria. All dogs were hypothyroid and severely hyperlipidemic. Neurologic signs included tetraparesis, central and peripheral vestibular signs, facial paralysis, and paraparesis. Two dogs had an acute history and rapid resolution of signs consistent with an infarct, the presence of which was confirmed in 1 of the dogs by magnetic resonance imaging. Two dogs had chronic histories of cranial neuropathies and paraparesis. One of these dogs had evidence of iliac thrombosis and atherosclerosis on ultrasound examination. All dogs improved with thyroid hormone supplementation. Labrador Retrievers may be predisposed to the development of severe hyperlipidemia in association with hypothyroidism. One possible consequence of severe hyperlipidemia is the development of neurologic signs due to atherosclerosis and thromboembolic events.

Decrease of blood lipids induced by Shan-Zha (fruit of Crataegus pinnatifida) is mainly related to an increase of PPARα in liver of mice fed high-fat diet.

Hyperlipidemia is an important risk factor for cardiovascular diseases. Agents for the treatment of hyperlipidemia are well-developed in the clinic while PPARα is a target for lipid-lowering agents. Shan-Zha (Crataegus pinnatifida) is a traditional Chinese medicine used to increase digestion. Also, Shan-Zha fruit extract showed merit to improve obesity and hyperlipidemia in hamsters; however, the mechanism remained obscure. In the present study, hypertriglycemia and hypercholesterolemia were induced by high fat diet in C57BL/6 J male mice. Then, they were orally administered with Shan-Zha fruit extract at an effective dose of 250 mg/kg for 7 days. The liver was removed to estimate the expressions of PPARα and β-oxidation-related enzyme. Oral intake of Shan-Zha extract significantly improved hyperlipidemia in high fat diet-fed mice with an increase of PPARα expression in liver. Also, expression of PPARα-regulated β-oxidation-related enzymes was raised in liver by Shan-Zha extract. However, adipose tissue and others were not modified by this treatment of Shan-Zha fruit extract. Thus, Shan-Zha can increase the expression of PPARα to facilitate β-oxidation-related enzymes in liver for lipid degradation and blood lipid decrement. Also, this is the first report showing Shan-Zha fruit extract can influence liver to lower hyperlipidemia prior to the action in adipose tissue. Georg Thieme Verlag KG Stuttgart · New York.

Starchy foods are the main sources of carbohydrates; however, there is limited information on their metabolic impact. Therefore, we assessed the association between carbohydrates from starchy foods (Carb-S) intakes and the metabolic disorders of metabolic syndrome (MetS) and hyperlipidemia. In this study, 4,154 participants from Northern China were followed up for 4.2 years. Carb-S included rice, refined wheat, tubers, and their products. Multivariable regression models were used to calculate risk ratios (RRs) for MetS and hyperlipidemia from Carb-S, total carbohydrates, and carbohydrates from other food sources (Carb-O). Receiver operating characteristic analysis was used to determine a Carb-S cut-off value. High total carbohydrate intake was associated with increased risks of MetS (RR: 2.24, 95% CI: 1.00–5.03) and hyperlipidemia (RR: 3.05, 95% CI: 1.25–7.45), compared with the first quartile. High Carb-S intake (fourth quartile) was significantly associated with MetS (RR: 1.48, 95% CI: 1.01–2.69) and hyperlipidemia (RR: 1.73, 95% CI: 1.05–3.35). No associations with Carb-O were observed. Visceral adiposity, triglyceride levels, and high-density lipoprotein cholesterol significantly contributed to the metabolic disorders. The Carb-S cut-off value was 220 g. Both high total carbohydrate and Carb-S intakes were associated with hyperlipidemia and MetS; Carb-S appears to contribute more to these disorders. PMID:26581652

Background Hyperlipidemia animal models have been established, but complete gene expression profiles of the transition from normal lipid levels have not been obtained. Miniature pigs are useful model animals for gene expression studies on dietary-induced hyperlipidemia because they have a similar anatomy and digestive physiology to humans, and blood samples can be obtained from them repeatedly. Methodology Two typical dietary treatments were used for dietary-induced hyperlipidemia models, by using specific pathogen-free (SPF) Clawn miniature pigs. One was a high-fat and high-cholesterol diet (HFCD) and the other was a high-fat, high-cholesterol, and high-sucrose diet (HFCSD). Microarray analyses were conducted from whole blood samples during the dietary period and from white blood cells at the end of the dietary period to evaluate the transition of expression profiles of the two dietary models. Principal Findings Variations in whole blood gene expression intensity within the HFCD or the HFCSD group were in the same range as the controls provide with normal diet at all periods. This indicates uniformity of dietary-induced hyperlipidemia for our dietary protocols. Gene ontology- (GO) based functional analyses revealed that characteristics of the common changes between HFCD and HFCSD were involved in inflammatory responses and reproduction. The correlation coefficient between whole blood and white blood cell expression profiles at 27 weeks with the HFCSD diet was significantly lower than that of the control and HFCD diet groups. This may be due to the effects of RNA originating from the tissues and/or organs. Conclusions No statistically significant differences in fasting plasma lipids and glucose levels between the HFCD and HFCSD groups were observed. However, blood RNA analyses revealed different characteristics corresponding to the dietary protocols. In this study, whole blood RNA analyses proved to be a useful tool to evaluate transitions in dietary-induced hyperlipidemia gene expression profiles in miniature pigs. PMID:22662175

To examine the prevalence of hyperlipidemia and its related factors in adults in rural Yuhuan, China. A cross-sectional study was carried out as a baseline study of Rural Yuhuan Health Population Cohort in all communities in Yuhuan County, Zhejiang Province, China. A total of 118,571 subjects aged 35 years old or above participated in this study. The trained health/medical workers collected the general information, health conditions and so on by the face-to-face interview. Totally, 5 ml blood samples were taken. Hyperlipidemia was defined as blood triglyceride > or = 1.70 mmol/L and/or total cholesterols > or = 5.18 mmol/L. SPSS 16.0 was used for statistical analysis. Data of the fifth China population census 2000 was used as the standard population. Among 118,571 eligible subjects, the averages of blood triglyceride and total cholesterols were (1.71 +/- 14.42) mmol/L and (5.48 +/- 40.25 ) mmol/L, respectively, and there was a statistical difference in gender on blood triglyceride (t = 4.163, P < 0.001) but not on blood total cholesterols. The crude prevalences of hyperchol-esterolemia, hypertriglyceridemia, both hypercholesterolemia and hypertriglyceridemia, and hyperlipidemia were 38.4%, 24.2%, 13.2% and 49.3% and the age-standardized prevalence were 36.6%, 23.8%, 12.7% and 47.7% based on 2000 China national population, respectively. These prevalences were higher in male than in female significantly and varied statistically over different age groups from the lowest group of 35-39 years old to highest group of 55-59 years old or 60-64 years old. A non-conditional binary logistic model showed that age, male, farmer, education levels, smoking, alcohol consumption and body mass index were significantly related to hyperlipidemia. Hyperlipidemia, especial hypercholesterolemia, was common in adults aged 35 years old or above living in rural China.

Accumulating evidence implicates gut microbiota as promising targets for the treatment of type 2 diabetes mellitus (T2DM). With a randomized clinical trial, we tested the hypothesis that alteration of gut microbiota may be involved in the alleviation of T2DM with hyperlipidemia by metformin and a specifically designed herbal formula (AMC). Four hundred fifty patients with T2DM and hyperlipidemia were randomly assigned to either the metformin- or AMC-treated group. After 12 weeks of treatment, 100 patients were randomly selected from each group and assessed for clinical improvement. The effects of the two drugs on the intestinal microbiota were evaluated by analyzing the V3 and V4 regions of the 16S rRNA gene by Illumina sequencing and multivariate statistical methods. Both metformin and AMC significantly alleviated hyperglycemia and hyperlipidemia and shifted gut microbiota structure in diabetic patients. They significantly increased a coabundant group represented by Blautia spp., which significantly correlated with the improvements in glucose and lipid homeostasis. However, AMC showed better efficacies in improving homeostasis model assessment of insulin resistance (HOMA-IR) and plasma triglyceride and also exerted a larger effect on gut microbiota. Furthermore, only AMC increased the coabundant group represented by Faecalibacterium spp., which was previously reported to be associated with the alleviation of T2DM in a randomized clinical trial. Metformin and the Chinese herbal formula may ameliorate type 2 diabetes with hyperlipidemia via enriching beneficial bacteria, such as Blautia and Faecalibacterium spp. IMPORTANCE Metabolic diseases such as T2DM and obesity have become a worldwide public health threat. Accumulating evidence indicates that gut microbiota can causatively arouse metabolic diseases, and thus the gut microbiota serves as a promising target for disease control. In this study, we evaluated the role of gut microbiota during improvements in hyperglycemia and hyperlipidemia by two drugs: metformin and a specifically designed Chinese herbal formula (AMC) for diabetic patients with hyperlipidemia. Both drugs significantly ameliorated blood glucose and lipid levels and shifted the gut microbiota. Blautia spp. were identified as being associated with improvements in glucose and lipid homeostasis for both drugs. AMC exerted larger effects on the gut microbiota together with better efficacies in improving HOMA-IR and plasma triglyceride levels, which were associated with the enrichment of Faecalibacterium spp. In brief, these data suggest that gut microbiota might be involved in the alleviation of diabetes with hyperlipidemia by metformin and the AMC herbal formula.

To assess the results of a single eye bank preparing a high volume of Descemet membrane endothelial keratoplasty (DMEK) tissues using multiple technicians to provide an overview of the experience and to identify possible risk factors for DMEK preparation failure. Cross-sectional study. setting: Lions VisionGift and Wilmer Eye Institute at Johns Hopkins Hospital. All 563 corneal tissues processed by technicians at Lions VisionGift for DMEK between October 2011 and May 2014 inclusive. Tissues were divided into 2 groups: DMEK preparation success and DMEK preparation failure. We compared donor characteristics, including past medical history. The overall tissue preparation failure rate was 5.2%. Univariate analysis showed diabetes mellitus (P = .000028) and its duration (P = .023), hypertension (P = .021), and hyperlipidemia or obesity (P = .0004) were more common in the failure group. Multivariate analysis showed diabetes mellitus (P = .0001) and hyperlipidemia or obesity (P = .0142) were more common in the failure group. Elimination of tissues from donors either with diabetes or with hyperlipidemia or obesity reduced the failure rate from 5.2% to 2.2%. Trends toward lower failure rates occurring with increased technician experience also were found. Our work showed that tissues from donors with diabetes mellitus (especially with longer disease duration) and hyperlipidemia or obesity were associated with higher failure rates in DMEK preparation. Elimination of tissues from donors either with diabetes mellitus or with hyperlipidemia or obesity reduced the failure rate. In addition, our data may provide useful initial guidelines and benchmark values for eye banks seeking to establish and maintain DMEK programs. Copyright © 2015 Elsevier Inc. All rights reserved.

Although hyperlipidemia is a well known adverse event of atypical antipsychotic (AAP) medication, there are few studies that have quantitatively compared the risks of various AAPs. Our aim was to comparatively evaluate the risk of hyperlipidemia associated with the use of AAPs approved in Japan through a consecutive epidemiological study. We conducted a sequence symmetry analysis (SSA) using health insurance claims data to analyze the following nine AAPs approved for use in Japan: risperidone, paliperidone, perospirone hydrochloride hydrate, blonanserin, clozapine, olanzapine, quetiapine fumarate, aripiprazole, and zotepine. Exposed cases were identified from drug dispensing records as those who had been administered both AAPs and antihyperlipidemic drugs. The adjusted sequence ratio (ASR) and 95 % confidence interval (CI) for each individual AAP and for all AAPs were calculated while controlling for time trends in dispensing patterns. Olanzapine was significantly associated with increased hyperlipidemia occurrence (ASR 1.56; 95 % CI 1.25-1.95). The ASRs obtained for risperidone (1.01; 95 % CI 0.80-1.27), perospirone hydrochloride hydrate (0.93; 95 % CI 0.63-1.39), blonanserin (0.83; 95 % CI 0.52-1.33), quetiapine fumarate (0.93; 95 % CI 0.73-1.18), and aripiprazole (1.02; 95 % CI 0.82-1.26) were approximately 1.0. Unstable estimates (wide CIs) were obtained for paliperidone and zotepine due to the small sample sizes. Among the AAPs used in Japan, only olanzapine was found to have an elevated risk of hyperlipidemia. In contrast, risperidone, perospirone hydrochloride hydrate, blonanserin, quetiapine fumarate, and aripiprazole had relatively low risks.

Hyperlipidemia has been implicated in atherosclerosis which is the leading cause of death among world population and resulting from lipid metabolic changes is a major cause of atherosclerosis. Bambusae Caulis in Taeniam belongs to Bambusaceae is the stem of Phyllostachys nigra (Lodd.) Munro var. henonis (Bean) Stapf of Phyllostachys bambusoides Siebold et Zuccarini, the perennial evergreen tree. The green middle layer of stem is dried in string-shape I shadow after the bark had been removed. In this study, the effects of middle layer of PN, PB, PP, and BCT on rat with hyperlipidemia, induced by Triton WR-1339 and high cholesterol diet were investigated. We measured plasma levels of triglyceride, total cholesterol, low-density lipoprotein (LDL)-cholesterol, and high-density lipoprotein (HDL)-cholesterol as measure of its hyperlipidemic effects. As a result, all of the Bambusae Caulis in Taeniam was reduced total cholesterol, LDL. Inhibition rate on LDL-oxidation, hACAT-1, and hACAT-2 was increased dose-dependently. Therefore all of the Bambusae Caulis in Taeniam is a good candidate for the treatment on Triton WR-1339 and high cholesterol diet-induced blood circulatory disorders, obesity, and hyperlipidemia.

It has been demonstrated that mangiferin can ameliorate hypertriglyceridemia by modulating the expression levels of genes involved in lipid metabolism in animal experiments, but its effects on the serum metabolic fingerprinting of hyperlipidemia animal models have not been reported. Thus, a NMR-based metabolomics approach was conducted to explore the effects of mangiferin on hyperlipidemia hamsters and to gain a better understanding of the involved metabolic pathways. Hamsters fed with a high-fat diet were orally administered with mangiferin 150 mg per kg BW once a day for 8 weeks. Serum samples were analysed by 1 H NMR, and multivariate statistical analysis was applied to the data to identify potential biomarkers. In total, 20 discriminating metabolites were identified. It turned out that mangiferin administration can partly reverse the metabolism disorders induced by a high-fat diet and exerted a good anti-hypertriglyceridemia effect. Mangiferin ameliorated hyperlipidemia by intervening in some major metabolic pathways, involving glycolysis, the TCA cycle, synthesis of ketone bodies, and BCAAs as well as choline and lipid metabolism. These findings provided new essential information on the effects of mangiferin and demonstrated the great potential of this nutrimetabolomics approach.

Alcohol-induced hyperlipidemia is positively correlated with cardiovascular diseases. Several herbal extracts have been reported to protect the cardiac injury and suppress the hyperlipidemia. However, the effect of ginger extracts on alcohol-induced hyperlipidemia and associated myocardial damage remains unclear. This study investigated the cardio-protective properties of ginger ethanolic extract (Gt) against alcohol-induced myocardial damage, and further distinguished the association between hyperlipidemia and occurrence of myocardial damage in rats. Twenty four Wistar male albino rats (250 ± 20 g) were divided into four groups including, Normal control (NC) (0.9% NaCl), Ginger treated (Gt) (200 mg/Kg b.w.), Alcohol treated (At) (20% of 6g/kg b.w. alcohol), and Alcohol along with Ginger treatment (At+Gt). In this study, lipid profiles such as fatty acids, triglycerides, total cholesterol, phospholipids, low density lipoprotein and high density lipoproteins, and cardiac biomarkers, including LDH, AST, CK-MB, cTn-T and cTn-I were examined in rats. Furthermore, histopathological studies were also conducted. We found that alcohol-induced myocardial damage was associated with increased lipid profile except high density lipoprotein in alcohol treated (20%, 6g/kg b.w.) rats compared with control. Ginger treatment significantly reduced the alcohol-induced lipid profiles except high density lipoproteins. Furthermore, elevated cardiac biomarkers activity with alcohol intoxication was substantially suppressed by ginger treatment. In addition, ginger treatment for 7-weeks significantly minimized the alcohol-induced myocardial damage. Our results concluded that ginger could protect alcohol-induced myocardial damage by suppression of hyperlipidemia and cardiac biomarkers. Ginger extract could alleviate the myocardial injury partially due to the suppression of circulating FFAs and TG levels.Increased circulating cholesterol, LDL and phospholipids with alcohol intake were substantially suppressed by ginger treatmentAlcohol, induced an increase in cardiac damage biomarkers, CK-MB, cTn-T and cTn-I were remarkably suppressed by ginger treatmentPerformed histopathological studies by transmission electron microscopy and light microscopy shows additional convincing evidence on ginger cardio-protective effects. The drastic changes were rehabilitated in cardiac tissue by ginger treatment may be it acts as a good antioxidant and possessing hypolipidemic activity.Collectively, our findings confirm hypothesis that ginger has cardio protective potential through suppression of hyperlipidemia, preserving the tissue damage bio markers, cardiac biomarkers in plasma and preservation of histoarchitecture of myocytes.

Family physicians have the potential to make a major impact on reducing the burden of cardiovascular disease through the optimal assessment and management of hyperlipidemia. We were interested in assessing the knowledge, beliefs, and self-reported practice patterns of a representative sample of family physicians regarding the assessment and management of hyperlipidemia 2 years after the release of the evidence-based National Cholesterol Education Program (NCEP) Adult Treatment Panel (ATP) III guidelines. A 33-item survey was mailed to a random sample (N = 1200) of members of the American Academy of Family Physicians in April of 2004, with 2 follow-up mailings to nonresponders. Physicians were queried about sociodemographic characteristics, their knowledge, attitudes, and self-reported practice patterns regarding the assessment and management of hyperlipidemia. Four case scenarios also were presented. Response rate was 58%. Over 90% of surveyed family physicians screened adults for hyperlipidemia as part of a cardiovascular disease prevention strategy. Most (89%) did this screening by themselves without the support of office staff, and 36% reported routine use of a flow sheet. Most had heard of the ATP III guidelines (85%), but only 13% had read them carefully. Only 17% of respondents used a coronary heart disease (CHD) risk calculator usually or always. Over 90% of those responding reported using low-density lipoprotein (LDL) as the treatment goal but only 76% reported using non-high-density lipoprotein (HDL) cholesterol as a secondary goal of therapy. We found a large variability in knowledge, beliefs, and practice patterns among practicing family physicians. We found general agreement on universal screening of adults for hyperlipidemia as part of cardiovascular disease prevention strategy and use of LDL cholesterol as a treatment goal. Many other aspects of the NCEP ATP III guidelines, such as use of a systematic, multidisciplinary approach, using non-HDL cholesterol as a secondary goal, routinely using a CHD risk calculator for risk assessment to guide cholesterol management, have not yet penetrated into self-reported clinical practice.

The silkworm is the larva or caterpillar of the domesticated silkmoth, Bombyx mori and being a primary producer of silk is an economically important insect. These days the silk is emerging as a resource for solving a broad range of biological problems. The silk (Abresham) is popularly known as Abresham muqriz (muqriz means cut) in Unani medicine. Its cocoons are extensively used as an ingredient of various Unani formulations like Khameer-E- Abresham Sada, Khameere Abresham Hakeem Arshad Wala, Khameere Abresham Ood Mastagi Wala etc. and are used to treat many cardiac and nervous disorders. The hypolipidemic activity of this drug, along with Nepata Hindostana (Badranjboya) and Terminalia Arjuna (Arjan) has been documented. But action of extract of Bombyx mori cocoons as a single drug is not documented. That's why; it was decided to study its effect on hyperlipidemia and atherosclerosis. The Male New Zealand White rabbits all of 1.5kgs were selected for the study. After stabilization period (2 weeks) the rabbits were divided into 3 groups (Group I - Control, Group II Lesion Control and Group III treated with extract of Bombyx mori silk cocoon). Hyperlipidemia and atherosclerosis were induced with 1% cholesterol diet. After induction of hyperlipidemia and atherosclerosis for twelve weeks, Group III rabbits were treated with Bombyx mori for 6 weeks (45 days). A significant decrease in hyperlipidemia was seen within 4 weeks of treatment. Histopathologically, the atherosclerotic plaques showed reduction in size. The third group showed a significant increase in the body weight and also an increase in the HDL cholesterol levels. The study concludes that extract of Bombyx mori cocoons has a significant effect on hypercholesterolemia and atherosclerosis probably because of its antioxidant and hypolipidemic effect.

Children with primary hyperlipidemia are prone to develop premature atherosclerosis, possibly associated with increased oxidative stress. Nutritional therapy is the primary strategy in the treatment of hyperlipidemia and associated conditions. Dietary interventions with bioactive-rich foods, such as nuts, may contribute to the modulation of both lipid profile and the oxidative/antioxidant status. Our study aimed to assess the impact of a dietary intervention with hazelnuts on selected oxidative stress markers in children and adolescents with primary hyperlipidemia. A single-blind, 8-week, randomized, controlled, three-arm, parallel-group study was performed. Children and adolescents diagnosed with primary hyperlipidemia (n=60) received dietary guidelines and were randomized into three groups: group 1 received hazelnuts with skin (HZN+S), and group 2 hazelnuts without skin (HZN-S), at equivalent doses (15-30 g/day, based on body weight); group 3 (controls) received only dietary recommendations (no nuts). At baseline and after 8 weeks, plasma oxidized low-density lipoprotein (ox-LDL) concentrations, oxidative levels of DNA damage in PBMCs and potential correlation with changes in serum lipids were examined. A reduction of endogenous DNA damage by 18.9%±51.3% (P=.002) and 23.1%±47.9% (P=.007) was observed after HZN+S and HZN-S, respectively. Oxidatively induced DNA strand breaks decreased by 16.0%±38.2% (P=.02) following HZN+S treatment. Ox-LDL levels did not change after HZN+S intervention but positively correlated with total cholesterol and LDL cholesterol. A short-term hazelnut intervention improves cell DNA protection and resistance against oxidative stress but not ox-LDL in hyperlipidemic pediatric patients.

Objective The aim of this study is to evaluate the relationship between periodontitis and hyperlipidemia risks through Meta-analysis. Methods Two researchers conducted an electronic search on PubMed, Cochrane Library, Embase, CBM, CNKI, Wanfang and VIP databases established until July 2016 for observational studies on the association between periodontitis and hyperlipidemia. The language used was limited to Chinese and English. After data extraction and quality evaluation of included trials, Meta-analysis was conducted using the RevMan 5.3 software. The GRADE 3.6 software was used to evaluate the quality level of the evidence. Results Six case-control studies and one cohort study were included. The results of Meta-analysis showed that serum triglyceride (TG) in patients with periodontitis was significantly higher than that of the periodontal health group (MD=50.50, 95% confidence interval=39.57-61.42, P<0.000 01), as well as serum total cholesterol (TC) (MD=17.54, 95% confidence interval=10.91-24.18, P<0.000 01). Furthermore, the risks of TG and TC in the serum of patients with chronic periodontitis were 4.73 times (OR=4.73, 95% confidence interval=2.74-8.17, P<0.000 01) and 3.62 times (OR=3.62, 95% confidence interval=2.18-6.03, P<0.000 01) of that of periodontal healthy patients. No significant difference was observed between the group with high-density lipoprotein cholesterol (HDL-C) and that with low density lipoprotein cholesterol (LDL-C). Conclusion Current evidence indicates that a correlation exists between chronic periodontitis and hyperlipidemia, and chronic periodontitis is an independent risk factor for hyperlipidemia, especially for TC and TG in serum.

Racial/ethnic differences in shared decision making about cardiovascular risk-reduction therapy could affect health disparities. To investigate whether patient race/ethnicity is associated with experiences discussing cardiovascular risk-reduction therapy with health care providers. National sample of US adults identified by random-digit dialing. Cross-sectional survey conducted in November 2006 to May 2007. Among participants in the National Survey of Medical Decisions (DECISIONS), a nationally representative sample of English-speaking US adults aged 40 and older, the authors analyzed respondents who reported discussing hyperlipidemia or hypertension medications with a health care provider in the previous 2 years. In multivariate linear and logistic regressions adjusting for age, gender, income, insurance status, perceived health, and current therapy, they assessed the relation between race/ethnicity (black/Hispanic v. white) and decision making: knowledge, discussion of pros and cons of therapy, discussion of patient preference, who made the final decision, preferred involvement, and confidence in the decision. Of respondents who discussed high cholesterol (N = 738) or hypertension (N = 745) medications, 88% were white, 9% black, and 4% Hispanic. Minorities had lower knowledge scores than whites for hyperlipidemia (42% v. 52%, difference -10% [95% confidence interval (CI): 15, -5], P < 0.001), but not for hypertension. For hyperlipidemia, minorities were more likely than whites to report that the health care provider made the final decision for treatment (31.7% v. 12.3% whites, difference 19.4% [95% CI: 6.9, 33.1%], P < 0.01); this was not true for hypertension. Possible limitations include the small percentage of minorities in the sample and potential recall bias. Minorities considering hyperlipidemia therapy may be less informed about and less involved in the final decision-making process.

Background: Hawthorn (Crataegus pinnatifida) is a Chinese medicinal plant traditionally used in the treatment of hyperlipidemia. Recently, studies indicated free radical scavenging was one of the major pathways to alleviate hyperlipidemia. Moreover, hawthorn fruit is a rich source of phenols, which quench free radical and attenuate hyperlipidemia. However, the phenols vary with processing methods, especially solvent type. Objective: Our aim was to compare hypolipidemic and antioxidant effects of aqueous and ethanol extracts of hawthorn fruit in hyperlipidemia rats. Materials and Methods: After a 4-week treatment of high-fat emulsion, lipid profile levels and antioxidant levels of two extracts were determined using commercial analysis. Total phenols content in the extract of hawthorn fruit was determined colorimetrically by the Folin–Ciocalteu method. Results: Both ethanol and aqueous extracts of hawthorn fruit possessed hypolipidemic and antioxidant activities. Simultaneously, stronger activities were observed in ethanol extract. Besides, total phenols content in ethanol extract from the same quality of hawthorn fruit was 3.9 times more than that in aqueous extract. Conclusion: The obvious difference of hypolipidemic and antioxidant effects between ethanol extract and aqueous extract of hawthorn fruit was probably due to the presence of total phenols content, under the influence of extraction solvent. SUMMARY Ethanol extract of hawthorn fruit exhibited more favorable hypolipidemic and antioxidant effects than aqueous extract. The higher effects could be due to the higher content of total phenols that varies with extraction solvent.

Obesity and hyperlipidemia are critical risk factors for atherosclerosis. Because ablation of NG2 proteoglycan in mice leads to hyperlipidemia and obesity, we investigated the impact of NG2 ablation on atherosclerosis in apoE null mice. Immunostaining indicates that NG2 expression in plaque, primarily by synthetic smooth muscle cells, increases during atherogenesis. NG2 ablation unexpectedly results in decreased (30%) plaque development, despite aggravated obesity and hyperlipidemia. Mechanistic studies reveal that NG2-positive plaque synthetic smooth muscle cells in culture can sequester low-density lipoprotein to enhance foam-cell formation, processes in which NG2 itself plays direct roles. In agreement with these observations, low-density lipoprotein retention and lipid accumulation in the NG2/ApoE knockout aorta is 30% less than that seen in the control aorta. These results indicate that synthetic smooth muscle cell-dependent low-density lipoprotein retention and foam cell formation outweigh obesity and hyperlipidemia in promoting mouse atherogenesis. Our study sheds new light on the role of synthetic smooth muscle cells during atherogenesis. Blocking plaque NG2 or altering synthetic smooth muscle cells function may be promising therapeutic strategies for atherosclerosis. © 2015 American Heart Association, Inc.

Olive oil is the primary source of fat in the Mediterranean diet, which is associated with a significant improvement in health status, as measured by reduced mortality from several chronic diseases. The current pandemic of obesity, metabolic syndrome, and type 2 diabetes is intimately associated with an atherogenic dyslipidemic phenotype. The core components of the dyslipidemia of the metabolic syndrome, which most likely initiate atherosclerosis, are the "lipid triad" consisting of high plasma triglycerides, low levels of high-density lipoproteins, and a preponderance of small, dense low-density lipoproteins at fasting. However, postprandial (non-fasting) TGs (postprandial hyperlipidemia) are also recognized as an important component for atherosclerosis. Herein, the purpose of this review was to provide an update on the effects and mechanisms related to olive oil on postprandial hyperlipidemia and its implications for the onset and progression of atherosclerosis and metabolic syndrome.

Perceptions of illness affect cardiovascular disease (CVD) self-management. This study explores knowledge, attitudes, and beliefs regarding hypertension and hyperlipidemia management among 34 African-American men with hypertension and/or hyperlipidemia, age 40-65, living in the Southeastern United States. In-person focus groups were conducted using semi-structured interview questions informed by the Health Belief Model (HBM). Participants had a high level of knowledge about hypertension self-management, but less about cholesterol self-management. Perceived severity of both conditions was acknowledged, though participants perceived hypertension as more severe. Barriers to self-management included medication side effects and unhealthy dietary patterns. Facilitators included social support, positive healthcare experiences, and the value placed on family. Cultural implications highlighted the importance of food in daily life and social settings. Participants expressed how notions of masculinity affected self-management-noting the impact of feelings of vulnerability and perceived lack of control stemming from diagnosis and treatment expectations. The findings highlight gaps in knowledge of hyperlipidemia versus hypertension, and the impact of cultural context and perceptions on engagement in self-management behaviors. Public health practitioners and healthcare providers serving African-American men should address cultural factors and notions of masculinity which can hinder effective disease management among this population.

Previous studies have shown that fermentations can enhance the bioactivity and absorption rate of soybean products. Fermented soybean products can alleviate hyperlipidemia and decrease risks of atherosclerosis and cardiovascular diseases. This study aimed to investigate the effects and mechanisms of soymilk fermented by Lactococcus acidophilus on blood lipids and antioxidant enzyme activities of rats fed with a high fat diet. Sixty rats were randomly assigned to six groups: normal control group (NC), high-fat control group (HFC), positive control group (cholestyramine, PC), Lactococcus acidophilus group (LA), soymilk group (SM), and fermented soymilk group (FSM), respectively. The NC group was fed with a basic diet, while the other groups were fed with a high-fat diet. After the experimental period (6 W), rats were sacrificed by decapitation. Blood and liver were collected to measure the concentrations of lipids and antioxidant enzyme activities. Results demonstrated that fermented soymilk could regulate lipid levels, restore HDL-c and TG to normal levels, and lower the concentrations of LDL-c than hypolipidemic drugs in hyperlipidemia rats. More importantly, fermented soymilk caused significant reduction in arteriosclerosis index and coronary risk index. Fermented soymilk also improved antioxidant capacities of hyperlipidemia rats. The increase of aglycone isoflavones in fermented soymilk could explain the above phenomena. In conclusion, soymilk fermented by Lactococcus acidophilus reduced risks of arteriosclerosis and coronary heart disease by regulating lipid levels and improving the antioxidant capacities of hyperlipidemia rats.

Our previous studies have shown that mangiferin decreased serum triglycerides and free fatty acids (FFAs) by increasing FFAs oxidation in both animal and cell experiments. This study sought to evaluate the effects of mangiferin on serum lipid profiles in overweight patients with hyperlipidemia. Overweight patients with hyperlipidemia (serum triglyceride ≥ 1.70 mmol/L, and total cholesterol ≥ 5.2 mmol/L) were included in this double-blind randomized controlled trial. Participants were randomly allocated to groups, either receiving mangiferin (150 mg/day) or identical placebo for 12 weeks. The lipid profile and serum levels of mangiferin, glucose, L-carnitine, β-hydroxybutyrate, and acetoacetate were determined at baseline and 12 weeks. A total of 97 participants completed the trial. Compared with the placebo control, mangiferin supplementation significantly decreased the serum levels of triglycerides and FFAs, and insulin resistance index. Mangiferin supplementation also significantly increased the serum levels of mangiferin, high-density lipoprotein cholesterol, L-carnitine, β-hydroxybutyrate, and acetoacetate, and increased lipoprotein lipase activity. However, there were no differences in the serum levels of total cholesterol, low-density lipoprotein cholesterol, serum glucose, and insulin between groups. Mangiferin supplementation could improve serum lipid profiles by reducing serum triglycerides and FFAs in overweight patients with hyperlipidemia, partly due to the promotion of FFAs oxidation.

Aim: To evaluate the lipid-regulating effects of extract from Ginkgo biloba leaves (EGB) using pharmacological methods and metabonomic profiling in a rat model of diet-induced hyperlipidemia. Methods: EGB was orally administered at a dose level of 40 mg/kg in both the EGB-prevention and -treatment groups. All rat samples obtained were examined for known and potential biomarkers and enzyme activity using commercial assay kits and GC/MS-based metabonomic profiling coupled with principal component analysis (PCA). Results: The data obtained from the assay kits indicated that EGB reduced total cholesterol and low density lipoprotein cholesterol levels and increased high density lipoprotein cholesterol levels in rat plasma obtained from both the EGB-prevention and –treatment groups compared with those of the diet-induced hyperlipidemia group. EGB also increased the activities of lipoprotein lipase and hepatic lipase and excretion of fecal bile acid in rats from the EGB-prevention and–treatment groups. Using GC/MS-based metabonomic analysis, more than 40 endogenous metabolites were identified in rat plasma. PCA of rat plasma samples obtained using GC/MS produced a distinctive separation of the four treatment groups and sampling points within each group. Metabolic changes during hyperlipidemia formation and improvement resulting from EGB treatment were definitively monitored with PCA score plots. Furthermore, elevated levels of sorbitol, tyrosine, glutamine and glucose, and decreased levels of citric acid, galactose, palmitic acid, arachidonic acid, acetic acid, cholesterol, butyrate, creatinine, linoleate, ornithine and proline, were observed in the plasma of rats treated with EGB. Conclusion: EGB exerts multi-directional lipid-lowering effects on the rat metabonome, including limitation of the absorption of cholesterol, inactivation of HMGCoA and favorable regulation of profiles of essential polyunsaturated fatty acid (EFA). Further experiments are warranted to explore the mechanisms of action underlying the lipid-regulating effects of EGB against hyperlipidemia. PMID:19960012

Diet of high lipids cause hyperlipidemia, which marked by an increase of total cholesterols, triglycerides, LDL-C, and decreasing of HDL-C. Hyperlipidemia lead the occurrence of atherosclerosis, one of factors that trigger cardiovascular disease, as hypertention; coronary heart and stroke. Parijoto (M. speciosa) is endemic plants in Asia with a distribution center in Malaysia, Indonesia and Philippines. Parijoto contain phytochemical components such as flavonoids, saponins and kardenolin. Flavonoid potensial as an antioxidants and can improve the hyperlipidemia condition. This study was aimed to determine lipid profiles and atherogenic index of hyperlipidemic Wistar rats (R. norvegicus Berkenhout, 1769) which given the methanolic extract of Parijoto (M. speciosa). The research was done with pre and post test randomized control group design. Rats were given a mixture of duck yolk and reused cooking oil (1:1) orally as much as 1% of body weight (BW) for 30 days. After hyperlipidemia achieved, rats were divided into 5 group: normal rats, hyperlipidemic rats, hyperlipidemic rats were given the methanolic extract of Parijoto (M. speciosa) 500 mg/kg, 1000 mg/kg, and 1500 mg/kg BW. Blood samples were collected when rats in hyperlipidemia conditions and after treatment with the methanolic extract of Parijoto (M. speciosa) for 30 days. The data of total cholesterol, HDL-Cholesterol, LDL-Cholesterol level, and atherogenic index were analyzed using ANOVA followed by Tukey test at 5% significance level. The result showed that giving of methanolic extract of Parijoto (M. speciosa) in hyperlipidemic rats reduced the total cholesterol, LDL-Cholesterol levels, and increased of HDL-cholesterol levels significantly (p<0.01), so atherogenic index reduced significantly too (p<0.01). Total cholesterol and LDL-Cholesterol levels were positively correlated with the atherogenic index, whereas HDL-cholesterol levels were negatively correlated with the atherogenic index.

Clinicopathologic and histopathologic evidence of both endoperoxidation with hyperprostaglandinemia and hyperlipidemia in a 5-week-old infant with a hemophagocytic syndrome is reported. Institution of histiocytolytic (VP-16) and cyclo-oxygenase inhibitor (indomethacin) therapies returned the prostaglandin levels and lipid profile to a nearly normal state coincidental with clinical recovery. It appears that by reducing the cell mass of histiocytes and controlling the over-production of prostaglandins, some types of hemophagocytic syndrome can be reversed.

To determine rates of diabetes, hypertension, and hyperlipidemia in Cambodian refugees, and to assess the proportion whose conditions are satisfactorily managed in comparison to the general population. Self-report and laboratory/physical health assessment data obtained from a household probability sample of U.S.-residing Cambodian refugees (N = 331) in 2010-2011 were compared to a probability sample of the adult U.S. population (N = 6,360) from the 2009-2010 National Health and Nutrition Examination Survey. Prevalence of diabetes, hypertension and hyperlipidemia in Cambodian refugees greatly exceeded rates found in the age- and gender-adjusted U.S. Cambodian refugees with diagnosed hypertension or hyperlipidemia were less likely than their counterparts in the general U.S. population to have blood pressure and total cholesterol within recommended levels. Increased attention should be paid to prevention and management of diabetes and cardiovascular disease risk factors in the Cambodian refugee community. Research is needed to determine whether this pattern extends to other refugee groups.

Familial combined hyperlipidemia (FCH) is a frequent disorder associated with premature coronary artery disease. It is transmitted in an autosomal dominant manner, although there is not a unique gene involved. The diagnosis is performed using clinical criteria, and variability in lipid phenotype and family history of hyperlipidemia are necessaries. Frequently, the disorder is associated with type2 diabetes mellitus, arterial hypertension and central obesity. Patients with FCH are considered as high cardiovascular risk and the lipid target is an LDL-cholesterol <100mg/dL, and <70mg/dL if cardiovascular disease or type 2 diabetes are present. Patients with FCH require lipid lowering treatment using potent statins and sometimes, combined lipid-lowering treatment. Identification and management of other cardiovascular risk factors as type 2 diabetes and hypertension are fundamental to reduce cardiovascular disease burden. This document gives recommendations for the diagnosis and global treatment of patients with FCH directed to specialists and general practitioners. Copyright © 2014 Elsevier España, S.L.U.

Introduction Statins, particularly rosuvastatin, have recently become relevant in the setting of venous thrombosis. The objective of this study was to study the non-lipid lowering effects of rosuvastatin in venous thrombosis in mice with hyperlipidemia. Materials and Methods An inferior vena cava ligation model of venous thrombosis in mice was utilized. Saline or 5mg/kg of rosuvastatin was administered by gavage 48hs previous thrombosis. Blood, the inferior vena cava, thrombus, and liver were harvested 3, 6 hours, and 2 days post-thrombosis. Thrombus weight, inflammatory markers, and plasminogen activator inhibitor-1 expression and plasma levels were measured and neutrophil migration to the IVC was assessed. Results Rosuvastatin significantly decreased thrombus weight, plasminogen activator inhibitor-1 expression and plasma levels, expression of molecules related to the interleukin-6 pathway, and neutrophil migration into the vein wall. Conclusions This work supports the beneficial effects of rosuvastatin on venous thrombosis in mice with hyperlipidemia due to its non-lipid lowering effects. PMID:23276528

Pedunculoside (PE) is a novel triterpene saponin extracted from the dried barks of Ilex rotunda Thunb. The present study aims to explore lipid-lowering effects of PE on hyperlipidemia rat induced by high-fat diet. The rats were fed with the high-fat diet and subjected to intragastric administration of PE at doses of 30, 15, or 5 mg/kg daily for 7 weeks. The results demonstrated that treatment with PE for 7-week dramatically decreased serum total cholesterol (TC) and low-density lipoprotein cholesterol (LDL-C) and reduced liver TC in hyperlipidemia rat induced by high-fat diet. Furthermore, the results also showed that PE modulated the expression of enzymes involved in lipid metabolism including peroxisome proliferator-activated receptor α (PPAR-α), sterol regulatory element-binding protein 1 (SREBP-1), fatty acid synthase (FAS) and stearoyl CoA desaturase-1 (SCD-1) mRNA in liver. Besides, PE-treated group decreased weights and diameters of epididymal adipose hyperlipidemia rat. Mechanism study demonstrated that PE regulated PPAR-γ, CCAAT/Enhancer-binding Protein α (C/EBPα)、and SREBP-1 expression as well as inhibited phosphorylation of AMPK in MDI (methylisobutylxanthine, dexamethasone, insulin) induced-3T3L1 cells. Molecular Docking confirmed interaction between PE with proteins involving PPAR-γ, C/EBPα and SREBP-1. In summary, these findings may support that PE is a novel lipid-lowering drug candidate.

This review focuses on the efficacy and safety of effective herbal medicines in the management of hyperlipidemia in human. PubMed, Scopus, Google Scholar, Web of Science, and IranMedex databases were searched up to 11th May 2010. The search terms were "hyperlipidemia" and ("herbal medicine" or "medicine traditional", "extract plant") without narrowing or limiting search elements. All of the human studies on the effects of herbs with the key outcome of change in lipid profiles were included. Fifty three relevant clinical trials were reviewed for efficacy of plants. This study showed significant decrease in total cholesterol and LDL cholesterol after treatment with Daming capsule (DMC), chunghyul-dan, Glycyrrhiza glabra, garlic powder (Allicor), black tea, green tea, soy drink enriched with plant sterols, licorice, Satureja khuzestanica, Monascus purpureus Went rice, Fenugreek, Commiphora mukul (guggul), Achillea wilhelmsii C.

The aim of our study was to outline the prevalence of hyperlipidemia in patients who had high-frequency hearing loss and tinnitus due to noise exposure. We investigated the role of a low-cholesterol diet and antihyperlipidemic therapy to alleviate the severity of tinnitus and possibly promote hearing gain after therapy in patients with acoustic trauma. Forty-two hyperlipidemic patients with subjective tinnitus and hearing loss due to noise exposure were enrolled for the study. We placed patients on a low-cholesterol diet or antihyperlipidemic therapy and followed them for up to 24 months; then we designated two groups as either "unresponsive" (n = 22; no response to either of the therapies and still experiencing hyperlipidemia) or "responsive" (n = 20; lower cholesterol or triglyceride levels). We then compared tinnitus scores and hearing levels in the two groups. The difference between tinnitus scores in the unresponsive and responsive groups and the change in tinnitus scores before and after therapy in the responsive group were significant. When we compared self-rated tinnitus severity results in two groups after therapy, we found the difference was significant (p < .05). The difference between average air-conduction thresholds at high frequencies after the treatment in the two groups was also significant. The incidence of hyperlipidemia is high among patients with noise-induced hearing loss, and significant improvement by way of lowered tinnitus intensity and higher frequencies in average hearing thresholds can be achieved after lowering the serum lipid level.

We present a 5 years 8 months old girl with severe hyperlipidemia (high total cholesterol, and low density lipoprotein values, and also, ectopic fat pericardial deposit). She was treated with diet and cholestyramine, without diagnosis of her disease etiology. Growth detention, weight loss, retarded bone age and clinical signs of hypometabolism were recorded. Thyroid profile confirms hypothyroidism diagnosis. Based on positive anti-thyroid antibodies and clearly reduced thyroid volume, a diagnosis of autoimmune atrophic thyroiditis was made, a very unusual pathology in early infancy. Linear growth was affected by late diagnosis.

Despite widespread statin therapy, 91% of cardiac transplant patients have hyperlipidemia within 5 years from cardiac transplantation. The implications of this are profound, particularly given that coronary allograft vasculopathy is a leading cause of death. Unfortunately the solution is not easy, with problems of toleration at higher statin doses and a lack of good quality evidence for second line agents. We review the literature and discuss some of the key issues transplant physicians are faced with when considering alternatives to statin therapy. © 2012 Blackwell Publishing Ltd.

Asparaginase-associated concurrence of hyperlipidemia, hyperglobulinemia, and thrombocytosis is a rare complication requiring aggressive lipoprotein apheresis, but no one of currently available lipoprotein apheresis methods can simultaneously resolve the 3 abnormalities. Herein, we reported a construction of double-filtration plasmapheresis (DFPP) using a combination of centrifugal/membranous plasma separation techniques to successfully treat a patient with hyperlipidemia, hyperglobulinemia, and thrombocytosis. A male presented with severe hyperlipidemia, hyperglobulinemia, and thrombocytosis during asparaginase treatment for NK/T-cell lymphoblastic lymphoma and was scheduled to receive lipoprotein apheresis. To simultaneously remove lipoproteins, immunoglobulin, and deplete platelets from blood, a centrifuge/membrane hybrid DFPP was constructed as following steps: plasma and part of platelets were separated first from whole blood by centrifugal technique and then divided by a fraction plasma separator into 2 parts: platelets and plasma components with large size, which were discarded; and those containing albumin, which were returned to blood with a supplement of extrinsic albumin solution. DFPP lasted 240 minutes uneventfully, processing 5450-mL plasma. The concentrations of plasma components before DFPP were as follows: triglycerides 38.22 mmol/L, total cholesterols 22.98 mmol/L, immunoglobulin A (IgA) 15.7 g/L, IgG 12.7 g/L, and IgM 14.3 g/L; whereas after treatment were 5.69 mmol/L, 2.38 mmol/L, 2.5 g/L, 7.7 g/L, and 0.4 g/L, respectively. The respective reduction ratio was 85.1%, 89.6%, 83.9%, 39.4%, and 96.9%. Platelet count decreased by 40.4% (from 612 × 10(9)/L to 365 × 10(9)/L). Centrifuge/membrane hybrid DFPP can simultaneously remove lipoproteins, immunoglobulin, and deplete platelets, with a success in treatment of asparaginase treatment-induced hyperlipidemia, hyperglobulinemia, and thrombocytosis, and may be useful for patients requiring DFPP but with particular situations.

Systemic iron homeostasis is strictly governed in mammals; however, disordered iron metabolism (such as excess iron burden) is recognized as a risk factor for various types of diseases including AS (Atherosclerosis). The hepcidin-ferroportin axis plays the key role in regulation of iron homeostasis and modulation of this signaling could be a potential therapeutic strategy in the treatment of these diseases. TMP (Tetramethylpyrazine) has been reported to have therapeutical effect on AS. Here, we aimed to investigate the effect of iron overload under hyperlipidemia condition on the endothelial injury, inflammation and oxidative stress by employing FPN1 Tek-cre mouse model with or without TMP intervention. Subjects for this study were 80 FPN1 Tek-cre mice and 40 C57BL/6 mice and we randomly divided them into six groups: Group N: C57BL/6 mice with normal diet, Group M: C57BL/6 mice with high-fat diet, Group FN: FPN1 Tek-cre mice with normal diet, Group FNT: FPN1 Tek-cre mice with normal diet and TMP injection, Group FM: FPN1 Tek-cre mice with high-fat diet, Group FMT: FPN1 Tek-cre mice with high-fat diet and TMP injection. After seven days of treatment, blood samples were obtained to detect the levels of blood lipids, Hepcidin, NO, ET-1, ROS, MDA, SOD, IL-1, IL-6 and TNF-α respectively. The liver and aorta were used for testing the lipid deposition by using hematoxylin and eosin(HE). Hyperlipidemia could cause iron overload in the aorta and increased serum hepcidin level, particularly in FPN1 Tek-cre mice, and can be reversed by TMP intervention. Knockout of Fpn1 induced increase of serum hepcidin, exacerbated endothelial dysfunction, oxidative stress and inflammatory response, particularly under hyperlipidemia condition. TMP intervention attenuated these processes. Our study signifies the potential application of certain natural compounds to ameliorating iron disorders induced by hyperlipidemia and protecting on endothelial function through modulation of hepcidin-ferroportin signaling. © 2018 The Author(s).

Osteoporosis is linked to reduced bone mineral density (BMD) as a major risk factor for fragility fractures. Recent studies indicated an association between BMD and abnormally elevated lipid levels in blood as common indicators for hyperlipidemia. In this study, we assessed the protective effect of paeoniflorin, a phytochemical compound with multiple pharmacological activities, against hyperlipidemia-induced osteoporosis in rats fed a high-carbohydrate, high-fat diet (HCHF). The special diet-fed rats were subjected to an 8-week treatment with either paeoniflorin (20 mg/kg, daily) or vehicle. The control group received a normal diet during the entire study. At study conclusion, serum markers of lipid metabolism and bone turnover were measured. Bone strength was assessed by biomechanical testing, and femurs were scanned using micro-computed tomography to analyze trabecular and cortical bone structure. Interestingly, paeoniflorin controlled the serum lipid profile by significantly decreasing HCHF-induced high levels of total cholesterol, triglyceride, and low-density lipoprotein cholesterol. Paeoniflorin significantly improved trabecular and cortical parameters as well as femur length and width that were negatively affected by HCHF diet. Biomechanical strength testing showed that femurs of HCHF diet-fed rats endured significantly lower force but higher displacement and strain than those of control rats, whereas paeoniflorin reversed the negative effects. Moreover, paeoniflorin rescued osteoblast differentiation and cell spreading activities along with bone turnover markers. In conclusion, HCHF-induced hyperlipidemia caused adverse effects on the bone that were rescued by paeoniflorin treatment. Copyright © 2018 Elsevier Inc. All rights reserved.

Introduction Hypertension and hyperlipidemia are major cardiovascular disease risk factors. To modify them, patients often need to adopt healthier lifestyles and adhere to prescribed medications. However, patients’ adherence to recommended treatments has been suboptimal. Reducing out-of-pocket costs (ROPC) to patients may improve medication adherence and consequently improve health outcomes. This Community Guide systematic review examined the effectiveness of ROPC for medications prescribed for patients with hypertension and hyperlipidemia. Methods We assessed effectiveness and economics of ROPC for medications to treat hypertension, hyperlipidemia, or both. Per Community Guide review methods, reviewers identified, evaluated, and summarized available evidence published from January 1980 through July 2015. Results Eighteen studies were included in the analysis. ROPC interventions resulted in increased medication adherence for patients taking blood pressure and cholesterol medications by a median of 3.0 percentage points; proportion achieving 80% adherence to medication increased by 5.1 percentage points. Blood pressure and cholesterol outcomes also improved. Nine studies were included in the economic review, with a median intervention cost of $172 per person per year and a median change in health care cost of −$127 per person per year. Conclusion ROPC for medications to treat hypertension and hyperlipidemia is effective in increasing medication adherence, and, thus, improving blood pressure and cholesterol outcomes. Most ROPC interventions are implemented in combination with evidence-based health care interventions such as team-based care with medication counseling. An overall conclusion about the economics of the intervention could not be reached with the small body of inconsistent cost-benefit evidence. PMID:26605708

Physicians in Taiwan work in stressful workplaces and have heavy workloads, both of which may contribute to the occurrence of a stroke. However, it is not clear whether they have a higher risk of stroke. Therefore, we conducted a population-based cohort study to compare the risks of stroke between physicians and the general population and among subgroups of physicians in Taiwan. In the National Health Insurance Research Database of Taiwan, we identified 28,062 physicians and selected 84,186 age- and sex-matched nonmedical staff beneficiaries as the references. Using conditional logistic regression, we compared the prevalence of stroke between physicians and references. In addition, we made comparisons among subgroup of physicians defined by age, sex, comorbidity, specialty, and the level of hospital. During the study period, physicians had higher prevalence rates of hypertension (23.6% vs. 19.1%), hyperlipidemia (21.4% vs. 12.9%), and coronary artery disease (CAD) (6.4% vs. 5.7%) than the referent group, but they had a lower risk of stroke with an odds ratio of 0.61 (95% confidence interval = 0.55, 0.66) after adjusting for hypertension, diabetes, hyperlipidemia, CAD, and active worker. Among physicians, the risks were higher in those who were older or had hypertension, diabetes, hyperlipidemia, or CAD. Despite having higher prevalence rates of hypertension, hyperlipidemia, and CAD and working in stressful workplaces with heavy workloads, our study suggests that physicians in Taiwan have a lower risk of stroke compared with the general population. These results may indicate the benefits of higher awareness and more knowledge of diseases.

Minor ST-T changes are frequently observed on the electrocardiogram (ECG), but the risk of stroke associated with such changes is unclear.Methods and Results:In 10,642 subjects from the Japanese general population, we evaluated minor and major ST-T changes (major ST depression ≥0.1 mV) on ECGs obtained at annual health examinations. At baseline, minor ST-T changes were found in 10.7% of the subjects and 0.5% had major ST-T changes. Minor ST-T changes were associated with older age, female gender, higher systolic blood pressure, presence of hyperlipidemia, and use of antihypertensive medication. There were 375 stroke events during the follow-up period (128.7±28.1 months). In all subjects, minor ST-T changes (HR, 2.10; 95% CI: 1.57-2.81) and major ST-T changes (HR, 8.64; 95% CI: 4.44-16.82) were associated with an increased risk of stroke, but the stroke risk associated with minor ST-T changes had borderline significance after adjustment for conventional risk factors (P=0.055). In subgroup analysis, the risk of stroke was significantly associated with minor ST-T changes in subjects who had hyperlipidemia (HR, 1.75; 95% CI: 1.15-2.67) compared to those without hyperlipidemia (HR, 1.01; 95% CI: 0.64-1.59; P for interaction=0.016), even after adjustment for ECG-diagnosed left ventricular hypertrophy. Minor ST-T changes were particularly associated with a higher risk of stroke in subjects with hyperlipidemia and this association was independent of electrocardiographic left ventricular hypertrophy.

Traditional Chinese medicine (TCM) has definitely clinical effect in treating hyperlipidemia, but the action mechanism still need to be explored. Based on consulting Chinese Pharmacopoeia (2010), all the lipid-lowering Chinese patent medicines were analyzed by associated rules data mining method to explore high frequency herb pairs. The top three couplet medicines with high support degree were Puerariae Lobatae Radix-Crataegi Fructus, Salviae Miltiorrhizae Radix et Rhizoma-Crataegi Fructus, and Polygoni Multiflori Radix-Crataegi Fructus. The 20 main ingredients were selected from the herb pairs and docked with 3 key hyperlipidemia targets, namely 3-hydroxy-3-methylglutaryl coenzyme A reductase (HMG-CoA reductase), peroxisome proliferator activated receptor-α (PPAR-α ) and niemann-pick C1 like 1 (NPC1L1) to further discuss the molecular mechanism of the high frequency herb pairs, by using the docking program, LibDock. To construct evaluation rules for the ingredients of herb pairs, the root-mean-square deviation (RMSD) value between computed and initial complexes was first calculated to validate the fitness of LibDock models. Then, the key residues were also confirmed by analyzing the interactions of those 3 proteins and corresponding marketed drugs. The docking results showed that hyperin, puerarin, salvianolic acid A and polydatin can interact with two targets, and the other five compounds may be potent for at least one of the three targets. In this study, the multi-target effect of high frequency herb pairs for lipid-lowering was discussed on the molecular level, which can help further researching new multi-target anti-hyperlipidemia drug.

Noncommunicable disease (NCD) has become the leading cause of mortality and disease burden worldwide. A cross-sectional survey was carried out to investigate the prevalence of NCDs and risk factor control on dietary behaviors and dietary intake in China, Japan, and Korea. There were significant differences among the three countries on the prevalence of hypertension (24.5% in China, 17.6% in Korea, and 15.2% in Japan), diabetes (8.9% in China, 5.7% in Korea, and 4.8% in Japan), hyperlipidemia (13.1% in China, 9.2% in Korea, and 6.9% in Japan), and angina pectoris (3.6% in China, 1.7% in Korea, and 1.5% in Japan). The prevalence rate of hypertension, diabetes, hyperlipidemia, and angina pectoris was highest in China and lowest in Japan. However, 82.2%, 48.4%, and 64.4% of Chinese, Koreans, and Japanese presented good dietary behavior, respectively. Multivariable logistic regression analysis found that sex, age, and marital status were predictors of good dietary behavior. In addition, in comparison with subjects without hypertension, diabetes, or hyperlipidemia, subjects with hypertension, diabetes, or hyperlipidemia significantly improved their dietary behaviors and controlled their intake of salt, sugar, and oil. The prevalence of NCDs and trends in major modifiable risk factor control in China, Korea, and Japan remain troubling. Public efforts to introduce healthy lifestyle changes and systematic NCDs prevention programs are necessary to reduce the epidemic of NCDs in these three Asian countries.

The purpose of this randomized, double-blind, placebo-controlled, parallel comparison study was to evaluate the lipid-lowering effect of orally administrated nattokinase and nattokinase combined with red yeast rice (RYR) extract on blood lipids in patients with hyperlipidemia. A total of 47 patients with hyperlipidemia were assigned to one of three groups: 1. nattokinase-mono formula (50 mg/capsule), 2. combined formula of nattokinase with RYR (300 mg of extract/capsule) and 3. placebo. Subjects received a twice daily dose of two capsules for six months. The mono formula showed no effects on blood lipids until month six, while the combined formula ameliorated all of measured lipids starting from month one. In the combined group significant decreases were found with regard to: triglycerides (TG) by 15%, total cholesterol (TC) by 25%, low-density lipoprotein cholesterol (LDL-C) by 41%, TC/high-density lipoprotein cholesterol (HDL-C) ratio by 29.5%, and increases in HDL-C by 7.5%. These changes were sustained until the end of study. After controlling for baseline levels, only the combined group, but not mono group, showed a significant difference (p<0.0001) in TC, LDL-C and TC/HDL-C ratio when compared with the placebo group. In summary, this study provides long-term efficacy of nattokinase supplementation and shows that the combined formula has relatively more potent effects than the mono formula on lowering of blood lipids, suggesting that combined nattokinase with RYR will be a better neutraceutical for patients with hyperlipidemia than nattokinase alone.

A case report of cholestatic jaundice in a 25 year old woman, who had had jaundice at age 4 years, and had taken Stediril (a combined oral contraceptive) for 1 month, implicates either the pill or a possibly hereditary hyperlipidemia. The jaundice developed in 2 weeks with vomiting, epigastric pain, anorexia, then discolored urine and feces, and intense pruritus. On hospitalization the patient had moderate bilirubinemia (56 mg/1), low alkaline phosphatase (13 U.K.) and slightly high serum glutamate pyruvate transaminase (270 U.W.). There were elevated serum cholesterol (3 gm/1), triglycerides (2.05 gm/1), total lipids (10.6 gm/1), and a definitely increased pre-beta lipoprotein, suggesting hyperlipidemia type IV (Frederickson classification). Liver biopsy showed fibrosis of the portal spaces lymphocytic infiltration, canalicular and intrahepatocytic thrombi. On laparoscopy the liver had a regular lower border, normal volume color and surface. Albumin, prothrombin and flocculation tests were normal. The patient's jaundice lasted about 1 month, then liver function slowly improved, although pruritus remained intense. Probably this jaundice was due to oral contraceptives, in a patient predisposed either by jaundice in childhood or endogenous hyperlipidemia.

Familial combined hyperlipidemia (FCH) is a frequent disorder associated with premature coronary artery disease. It is transmitted in an autosomal dominant manner, although there is not a unique gene involved. The diagnosis is performed using clinical criteria, and variability in lipid phenotype and family history of hyperlipidemia are necessaries. Frequently, the disorder is associated with type2 diabetes mellitus, arterial hypertension and central obesity. Patients with FCH are considered as high cardiovascular risk and the lipid target is an LDL-cholesterol <100mg/dL, and <70mg/dL if cardiovascular disease or type 2 diabetes are present. Patients with FCH require lipid lowering treatment using potent statins and sometimes, combined lipid-lowering treatment. Identification and management of other cardiovascular risk factors as type 2 diabetes and hypertension are fundamental to reduce cardiovascular disease burden. This document gives recommendations for the diagnosis and global treatment of patients with FCH directed to specialists and general practitioners.

Alcoholics usually suffer from malnutrition and are especially deficient in micronutrients like vitamin C, selenium and Zn. In the present study, combined effects of selenium and ascorbic acid on alcohol-induced hyperlipidemia were studied in guinea pigs. Four groups of male guinea pigs were maintained for 45 days as follows: control (1 mg ascorbate (AA)/100 g body mass/day), ethanol (900 mg ethanol/100 g body mass + 1 mg AA/100 g body mass/day), selenium+ascorbic acid [(25 mg AA + 0.05 mg Se)/100 g body mass/day], ethanol+selenium+ascorbic acid [(25 mg AA + 0.05 mg Se + 900 mg ethanol)/100 g body mass/day]. Co-administration of selenium and ascorbic acid along with alcohol reduced the concentration of all lipids, as also evidenced from the decreased activities of hydroxymethylglutaryl-CoA reductase and enhanced activities of plasma lecithin cholesterol acyl transferase and lipoprotein lipase. Concentrations of bile acids were increased. We conclude that the supplementation of Se and ascorbic acid reduced alcohol induced hyperlipidemia, by decreased synthesis and increased catabolism.

Many older adults experience hyperlipidemia and hypertension, but there is little information about whether medical nutrition therapy (MNT) or therapeutic meals have independent or joint beneficial effects on older adults with these diagnoses. To assess the cost-effectiveness of MNT and therapeutic meals for older adults with hyperlipidemia and/or hypertension. A 1-year prospective four-arm controlled randomized community-based clinical trial. Participants were people ages 60 years or older residing in community settings who were medically diagnosed with either hypertension or hyperlipidemia. They were recruited through a number of venues beginning in May 2003. The 321 eligible individuals were assigned to one of four arms: (a) a literature control group, (b) a therapeutic meal group that received seven diagnosis-appropriate therapeutic meals a week, (c) an MNT group, and (d) an MNT-plus-therapeutic meal group. The outcome measure was quality-adjusted life-years (QALYs). Costs included both intervention and medical costs. Estimations of separate models of costs and QALYs facilitated the construction of incremental cost-effectiveness ratios. Net benefit analysis produced the probability that each intervention was cost-effective given different values for society's willingness to pay for a QALY. Therapeutic meals are cost-effective. Using the net benefit approach and a willingness to pay of $109,000 per QALY, the probability that the therapeutic meal delivery program is cost-effective is 95% and for MNT the probability is 90%. However, the combination of MNT and therapeutic meals did not have an independent significant effect on QALYs. Results inform the debate about extending Medicare funding for MNT to individuals with hypertension and hyperlipidemia. Future research should include more individuals who are not currently receiving medications for these diseases. Copyright © 2010 American Dietetic Association. Published by Elsevier Inc.

To improve bone strength prediction beyond limitations of assessment founded solely on the bone mineral component, we investigated the effect of hyperlipidemia, present in more than 40% of osteoporotic patients, on multiscale structure of murine bone. Our overarching purpose is to estimate bone strength accurately, to facilitate mitigating fracture morbidity and mortality in patients. Because (i) orientation of collagen type I affects, independently of degree of mineralization, cortical bone׳s micro-structural strength; and, (ii) hyperlipidemia affects collagen orientation and μCT volumetric tissue mineral density (vTMD) in murine cortical bone, we have constructed the first multiscale finite element (mFE), mouse-specific femoral model to study the effect of collagen orientation and vTMD on strength in Ldlr(-/-), a mouse model of hyperlipidemia, and its control wild type, on either high fat diet or normal diet. Each µCT scan-based mFE model included either element-specific elastic orthotropic properties calculated from collagen orientation and vTMD (collagen-density model) by experimentally validated formulation, or usual element-specific elastic isotropic material properties dependent on vTMD-only (density-only model). We found that collagen orientation, assessed by circularly polarized light and confocal microscopies, and vTMD, differed among groups and that microindentation results strongly correlate with elastic modulus of collagen-density models (r(2)=0.85, p=10(-5)). Collagen-density models yielded (1) larger strains, and therefore lower strength, in simulations of 3-point bending and physiological loading; and (2) higher correlation between mFE-predicted strength and 3-point bending experimental strength, than density-only models. This novel method supports ongoing translational research to achieve the as yet elusive goal of accurate bone strength prediction. Copyright © 2014 Elsevier Ltd. All rights reserved.

Standard approaches for large scale phenotypic screens using electronic health record (EHR) data apply thresholds, such as ≥2 diagnosis codes, to define subjects as having a phenotype. However, the variation in the accuracy of diagnosis codes can impair the power of such screens. Our objective was to develop and evaluate an approach which converts diagnosis codes into a probability of a phenotype (PheProb). We hypothesized that this alternate approach for defining phenotypes would improve power for genetic association studies. The PheProb approach employs unsupervised clustering to separate patients into 2 groups based on diagnosis codes. Subjects are assigned a probability of having the phenotype based on the number of diagnosis codes. This approach was developed using simulated EHR data and tested in a real world EHR cohort. In the latter, we tested the association between low density lipoprotein cholesterol (LDL-C) genetic risk alleles known for association with hyperlipidemia and hyperlipidemia codes (ICD-9 272.x). PheProb and thresholding approaches were compared. Among n = 1462 subjects in the real world EHR cohort, the threshold-based p-values for association between the genetic risk score (GRS) and hyperlipidemia were 0.126 (≥1 code), 0.123 (≥2 codes), and 0.142 (≥3 codes). The PheProb approach produced the expected significant association between the GRS and hyperlipidemia: p = .001. PheProb improves statistical power for association studies relative to standard thresholding approaches by leveraging information about the phenotype in the billing code counts. The PheProb approach has direct applications where efficient approaches are required, such as in Phenome-Wide Association Studies.

Type 2 diabetes is characterized by hyperlipidemia, hyperinsulinemia, and insulin resistance. The aim of this study was to investigate whether acute hyperlipidemia-induced insulin resistance in the presence of hyperinsulinemia was due to defective insulin signaling. Hyperinsulinemia (approximately 300 mU/l) with hyperlipidemia or glycerol (control) was produced in cannulated male Wistar rats for 0.5, 1 h, 3 h, or 5 h. The glucose infusion rate required to maintain euglycemia was significantly reduced by 3 h with lipid infusion and was further reduced after 5 h of infusion, with no difference in plasma insulin levels, indicating development of insulin resistance. Consistent with this finding, in vivo skeletal muscle glucose uptake (31%, P < 0.05) and glycogen synthesis rate (38%, P < 0.02) were significantly reduced after 5 h compared with 3 h of lipid infusion. Despite the development of insulin resistance, there was no difference in the phosphorylation state of multiple insulin-signaling intermediates or muscle diacylglyceride and ceramide content over the same time course. However, there was an increase in cumulative exposure to long-chain acyl-CoA (70%) with lipid infusion. Interestingly, although muscle pyruvate dehydrogenase kinase 4 protein content was decreased in hyperinsulinemic glycerol-infused rats, this decrease was blunted in muscle from hyperinsulinemic lipid-infused rats. Decreased pyruvate dehydrogenase complex activity was also observed in lipid- and insulin-infused animals (43%). Overall, these results suggest that acute reductions in muscle glucose metabolism in rats with hyperlipidemia and hyperinsulinemia are more likely a result of substrate competition than a significant early defect in insulin action or signaling.

Background Patients with schizophrenia have significantly shorter life expectancy than the general population, and a problem they commonly face is an unhealthy lifestyle, which can lead to obesity and metabolic syndrome. There is a very clear need to determine the prevalence of obesity, hypertension, hyperlipidemia, and diabetes mellitus which are components of metabolic syndrome in patients with schizophrenia, but there has been a paucity of large-scale studies examining this situation in Japan. The aim of our study was to address this need. Setting & Participants We conducted a large-scale investigation of the prevalence of obesity, hypertension, hyperlipidemia, and diabetes mellitus using a questionnaire in 520 outpatient facilities and 247 inpatient facilities of the Japan Psychiatric Hospitals Association between January 2012 and July 2013. There were 7,655 outpatients and 15,461 inpatients with schizophrenia. Results The outpatients had significantly higher prevalence of obesity, hypertension, hypertriglyceridemia, hyper-LDL cholesterolemia, and diabetes mellitus than the inpatients. The prevalence of hypo-HDL cholesterolemia was higher in inpatients than outpatients. Age-specific analysis showed the prevalence of obesity, hypertension, hypertriglyceridemia, hyper-LDL cholesterolemia, and diabetes mellitus among outpatients to be 2- to 3-fold higher than among inpatients. In individuals aged ≥60 years, the prevalence of obesity and DM among outpatients was about 3-fold higher than among inpatients. Conclusion Japanese outpatients with schizophrenia were more likely to have physical risk such as obesity, hypertension, hyperlipidemia, and diabetes mellitus than inpatients. The physical risk to patients with schizophrenia may be affected by environmental parameters, such as type of care. The physical risk to Japanese patients with schizophrenia demands greater attention. PMID:27855222

Hepatocellular carcinoma is the most common primary liver malignancy, commonly a sequelae of hepatitis C infection, but can complicate cirrhosis of any cause. Whether metabolic syndrome and its components, type II diabetes, hypertension, and hyperlipidemia increase the risk of hepatocellular carcinoma independent of cirrhosis is unknown. A retrospective cohort study was conducted using the MarketScan insurance claims database from 2008-2012. Individuals with hepatocellular carcinoma aged 19-64 years and age and sex-matched controls were included. Multivariate analysis of hepatocellular carcinoma risk factors was performed. Hepatitis C (odds ratio [OR] 2.102) was the largest risk factor for hepatocellular carcinoma. Other independent risk factors were type II diabetes (OR 1.353) and hypertension (OR 1.229). Hyperlipidemia was protective against hepatocellular carcinoma (OR 0.885). The largest risk increase occurred with hypertension with type II diabetes and hepatitis C (OR 4.580), although hypertension and type II diabetes without hepatitis C still incurred additional risk (OR 3.399). Type II diabetes and hyperlipidemia had a similar risk if hepatitis C was present (OR 2.319) or not (OR 2.395). Metformin (OR 0.706) and cholesterol medications (OR 0.645) were protective in diabetics. Insulin (OR 1.640) increased the risk of hepatocellular carcinoma compared with the general type II diabetes population. In the absence of cirrhosis, type II diabetes and hypertension were independent risk factors for hepatocellular carcinoma. Hyperlipidemia and medical management of type II diabetes with metformin and cholesterol medication appeared to reduce the incidence of hepatocellular carcinoma. In contrast, insulin was associated with a higher risk of hepatocellular carcinoma. Copyright © 2017 Elsevier Inc. All rights reserved.

Patients with schizophrenia have significantly shorter life expectancy than the general population, and a problem they commonly face is an unhealthy lifestyle, which can lead to obesity and metabolic syndrome. There is a very clear need to determine the prevalence of obesity, hypertension, hyperlipidemia, and diabetes mellitus which are components of metabolic syndrome in patients with schizophrenia, but there has been a paucity of large-scale studies examining this situation in Japan. The aim of our study was to address this need. We conducted a large-scale investigation of the prevalence of obesity, hypertension, hyperlipidemia, and diabetes mellitus using a questionnaire in 520 outpatient facilities and 247 inpatient facilities of the Japan Psychiatric Hospitals Association between January 2012 and July 2013. There were 7,655 outpatients and 15,461 inpatients with schizophrenia. The outpatients had significantly higher prevalence of obesity, hypertension, hypertriglyceridemia, hyper-LDL cholesterolemia, and diabetes mellitus than the inpatients. The prevalence of hypo-HDL cholesterolemia was higher in inpatients than outpatients. Age-specific analysis showed the prevalence of obesity, hypertension, hypertriglyceridemia, hyper-LDL cholesterolemia, and diabetes mellitus among outpatients to be 2- to 3-fold higher than among inpatients. In individuals aged ≥60 years, the prevalence of obesity and DM among outpatients was about 3-fold higher than among inpatients. Japanese outpatients with schizophrenia were more likely to have physical risk such as obesity, hypertension, hyperlipidemia, and diabetes mellitus than inpatients. The physical risk to patients with schizophrenia may be affected by environmental parameters, such as type of care. The physical risk to Japanese patients with schizophrenia demands greater attention.

Coronary artery calcification (CAC) is a specific indicator of and a sensitive marker for the atherosclerotic disease process. However, calcium scoring may miss noncalcified plaques with clinical importance. The present study aimed to identify the presence and extent of coronary plaques in computed tomography coronary angiography (CTCA) in patients with a zero CAC score and the secondary endpoint was to evaluate the association between coronary risk factors and the presence of noncalcified plaques. In a retrospective descriptive-analytic study, a total of 2000 consecutive patients who undergone CTCA between September 2012 and September 2014 at Alzahra Hospital in Isfahan, Iran were analyzed. Three hundred and eighty-five patients with a zero calcium score were included in the study. The demographic information and coronary artery disease (CAD), risk factors including diabetes mellitus (DM), hypertension, hyperlipidemia, smoking, and family history of CAD, were obtained from the questionnaire. Furthermore, the presence of plaques and extent of stenosis were evaluated in patients with zero CAC score. Of the 385 patients with a zero calcium score, 16 (4.2%) had atherosclerotic plaques. Among them, 6 (1.6%) had significant (>50%) coronary stenosis, and 10 (2.6%) had no significant (<50%) coronary stenosis. Hyperlipidemia, DM, and smoking were significantly associated with obstructive CAD. Furthermore, in patients with zero calcium score, DM, hyperlipidemia, and smoking had odds ratios of 5.9, 14, and 32.5 for the development of coronary artery plaques, respectively. Although, CAC scoring is a noninvasive and valuable method to evaluate CAD; but zero CAC score does not absolutely exclude the CAD, especially in the presence of risk factors such as diabetes, hyperlipidemia, and smoking.

Should pediatric patients with hyperlipidemia receive drug therapy?

Bhatnagar, Deepak

Hyperlipidemia is now established as a major risk factor for causation of coronary heart disease (CHD) in adults; however, there is much debate on the level of coronary risk at which lipid-lowering drugs should be used. These issues of possible harm or lack of benefit from long-term use of lipid-lowering therapy, and cost effectiveness, are also pertinent in the pediatric setting. Evidence from several countries indicates that children have an increasing prevalence of obesity, hyperlipidemia and type 2 diabetes mellitus. Children who have high serum lipids 'track' these increased levels into adulthood. In some countries there is a trend to screen children for hypercholesterolemia. Family history itself is a poor discriminator in determining which children need to be screened and treated. Estimation of apolipoprotein B and/or apolipoprotein E genotype can improve prediction. Measuring high density lipoprotein cholesterol also helps, but obesity appears to be the best marker for screening children at high risk. These considerations should not cloud the need for case finding and treatment of children with genetic disorders. Low fat diets have been shown to be well tolerated and effective in children; however, there are no major long-term studies demonstrating harm or benefit in those on lipid-lowering drugs. Nevertheless, concerns regarding the psychological effect and the theoretical metabolic effects of long-term lipid lowering remain. Lipid-lowering drugs should be generally restricted to children with genetic disorders of lipid metabolism. Children with diabetes mellitus, hypertension or nonlipid-related inherited disorders leading to premature CHD in adults should be treated with diet, and with lipid-lowering drugs when they reach adulthood. Children with secondary hyperlipidemia should be assessed individually. A number of drugs and nutriceuticals are available for use in children, but only a few drugs are licensed for use in children.

Chronic ethanol exposure causes hyperlipidemia. The present study was designed to investigate the impact of ascorbic acid supplementation on ethanol induced hyperlipidemia in testis and to compare it with that of abstinence from taking alcohol. Thirty-six male guinea pigs were divided into two groups and were maintained for 90 days as follows (1) control (C) (2) ethanol treated group (E) (4 g/kg body wt/day). Ethanol was administered for 90 days and on 90th day, alanine amino transaminase (ALT), aspartate amino transaminase (AST) and γ-glutamyltransferase (GGT) in serum was assayed. The animals in the ethanol group were further divided into an ascorbic acid supplemented group (25 mg/100 g body wt/day) (E+AA) and an ethanol abstention group (EAG) and those in the control group were divided into a control group and a control+ascorbic acid group (C+AA). There was significant increase in levels of testicular cholesterol, free fatty acid, phospholipids and triglycerides in the ethanol group. There was also a significant increase in the activity of HMG CoA reductase and decrease in activity of testicular glucose-6-phosphate dehydrogenase (G6PDH) and malic enzyme in ethanol-ingested animals that further led to decreased levels of serum testosterone. Alcohol administration also enhanced the activity of testicular alcohol dehydrogenase (ADH). Ascorbic acid supplementation and abstention altered all these parameters induced by chronic alcohol administration. Histological studies were also in line with the above results. Ascorbic acid was able to reinstate the cholesterol homeostasis in testis which could have further restored the testicular steroidogenesis. The present study demonstrated that ascorbic acid is effective in reducing the hyperlipidemia induced by chronic alcohol administration and produced a better recovery than abstention.

The medicinal plants Artemisia iwayomogi and Curcuma longa radix are both used to treat hyperlipidemia in traditional Korean and Chinese medicine. To evaluate the anti-hyperlipidemic effects of the 30% ethanol extracts of A. iwayomogi (AI), C. longa (CL), and the mixture of A. iwayomogi and C. longa (ACE), using a high-fat diet-induced hyperlipidemia model. Six of seven groups of C57BL/6N male mice (i.e., not including the naïve group) were fed a high-fat diet freely for 10 weeks. Of these six groups, five (i.e., not including the control group) were administered a high-fat diet supplemented with AI (100mg/kg), CL (100mg/kg), ACE (50 or 100mg/kg), or Lipitor (20mg/kg). Serum lipid profiles, obesity-related markers, hepatic steatosis, hepatic gene expression, and oxidative stress markers were analyzed. AI, CL, and ACE were associated with significant effects on serum lipid profiles (total cholesterol [TC] and triglyceride), body, liver and peritoneal adipose tissue weights, hepatic lipid accumulation, and oxidative stress biomarkers. ACE at 100mg/kg was associated with significantly greater improvements in serum TC and triglyceride, hepatic triglyceride, epididymal adipocyte size, and oxidative stress biomarkers, compared with AI and CL. AI, CL and ACE normalized lipid synthesis-associated gene expression (peroxisome proliferator-activated receptor gamma, fatty acid synthase, sterol regulatory element-binding transcription factor-1c, and peroxisome proliferator-activated receptor alpha). ACE exhibits anti-hyperlipidemia properties and is associated with partially synergistic effects compared with AI or CL alone. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

To forecast adult patient outcomes in the management of hyperlipidemia using adult National Health and Examination Survey III (NHANES III) population statistics and National Cholesterol Education Program (NCEP) guidelines for goals of therapy. Review of the hyperlipidemia drug therapy English-language medical literature with emphasis on randomized controlled trials of more than 6 weeks' duration published in the last 7 years, product package inserts, US Food and Drug Administration submission information, and NHANES III population statistics. Data were extracted from studies of lipid-lowering therapy to modify low-density lipoprotein (LDL) levels for primary and secondary prevention of coronary heart disease. The data that were evaluated included sample size, study design, therapeutic intervention, length of study, percentage change in LDL levels, and patient demographics. Cumulative frequency curves of the LDL distribution among the US adult population were constructed. The mean efficacy of drug therapy from qualified studies was used to extrapolate the percentage of the population expected to respond to the intervention and to forecast the patient outcome. A useful tool for clinicians was constructed to approximate the percentage of patients, based on risk stratification, who would reach NCEP target goal after a given pharmacotherapeutic intervention to decrease LDL levels.

Cocoa powder is rich in flavonoids, which have many beneficial effects on human health, including antioxidative and anti-inflammatory effects. The aim of our study was to investigate whether the intake of cocoa powder has any influence on hyperlipidemia and atherosclerosis and examine the underlying molecular mechanisms. We fed apoE knockout mice a Western diet supplemented with either 0.2% (low group) or 2% (high group) cocoa powder for 12 weeks. The groups fed dietary cocoa powder showed a significant reduction in both plasma cholesterol levels and aortic atherosclerosis compared to the control group. Analysis of mRNA profiling of aortic atherosclerotic lesions revealed that the expression of several genes related to apoptosis, lipid metabolism, and inflammation was significantly reduced, while the antiapoptotic gene Bcl2 was significantly increased in the cocoa powder group compared to the control. RT-PCR analysis along with Western blotting revealed that a diet containing cocoa powder inhibited the expression of hepatic endoplasmic reticulum stress. These data suggest that cocoa powder intake improves hyperlipidemia and atherosclerosis, and such beneficial effects are possibly mediated through the suppression of hepatic endoplasmic reticulum stress.

Abstract Migration inhibitory factor (MIF) has been shown to be critical in the pathology of early artherosclerosis; this article aim to investigate the plasma levels of MIF in hypertension plus hyperlipidemia patients. A total of 39 hypertension plus hyperlipidemia patients without any previous treatment were enrolled (HTN-HLP). Twenty-five healthy subjects were enrolled as the healthy control group (HEALTHY). Plasma MIF was measured by ELISA; laboratory and clinical characteristics were analyzed. HUVECs were treated with pooled plasma from HTN-HLP and HEALTHY groups, and the protein levels of adhesion molecules VCAM-1 and ICAM-1 were determined by ELISA. We found that plasma MIF was significantly elevated in the HTN-HLP group. Serum NO and eNOS levels were significantly lower; serum ET-1 (endothelin) levels were significantly higher in the HTN-HLP group. Furthermore, blood pressure, baPWV (brachial–ankle pulse wave velocity), and serum ET-1 level were significantly positively; serum NO and eNOS levels were negatively correlated with plasma MIF levels. Plasma from HTN-HLP significantly stimulated VCAM-1 and ICAM-1 protein expression on the surface of HUVECs. Plasma MIF was elevated in HTN-HLP patients and correlates with impaired endothelial function. PMID:27787379

Hyperlipidemia, characterized by the abnormal blood lipid profiles, is one of the dominant factors of many chronic diseases such as diabetes, obesity, and cardiovascular diseases (CVD). For the low cost, effectiveness, and fewer side effects, the popularity of using traditional Chinese medicine (TCM) to handle hyperlipidemia is increasing and its role in health care has been recognized by the public at large. Despite the importance of TCM herbs and formulations, there is no comprehensive review summarizing their scientific findings on handling hyperlipidemia. This review summarizes the recent experimental and clinical results of nine representative single Chinese herbs and seven classic TCM formulae that could improve lipid profiles so as to help understand and compare their underlying mechanisms. Most of single herbs and formulae demonstrated the improvement of hyperlipidemic conditions with multiple and diverse mechanisms of actions similar to conventional Western drugs in spite of their mild side effects. Due to increasing popularity of TCM, more extensive, well-designed preclinical and clinical trials on the potential synergistic and adverse side effects of herb-drug interactions as well as their mechanisms are warranted. Hyperlipidemic patients should be warned about the potential risks of herb-drug interactions, particularly those taking anticoagulants and antiplatelet drugs. PMID:25110708

ABSTRACT The antioxidant function of edible flowers have attracted increasing interest. However, information is lacking on the impact of edible flowers on oxidative injury including hypoxia-re-oxygenation and hyperlipidemia. The antioxidant activities of aqueous extracts from 12 Chinese edible flowers were assessed in four different antioxidant models, including total antioxidant capacity (TAC), oxygen radical absorbance capacity (ORAC), scavenging hydroxyl radical capacity (SHRC) and scavenging superoxide anion radical capacity (SSARC). Subsequently, the potential antioxidant effects on rat cardiac microvascular endothelial cells (rCMEC) treated with hypoxia-re-oxygenation and hyperlipidemia rats induced by high-fat diet were also evaluated. The highest TAC, ORAC, SHRC and SSARC were Lonicera japonica Thunb., Rosa rugosa Thunb., Chrysanthemum indicum L. and Rosa rugosa Thunb., respectively. Most aqueous extracts of edible flowers exhibited good antioxidant effects on injury of rCMEC induced by hypoxia-re-oxygenation. In addition, the aqueous extracts of Lonicera japonica Thunb., Carthamus tinctorius L., Magnolia officinalis Rehd. et Wils., Rosmarinus officinalis L. and Chrysanthemum morifolium Ramat. could suppress the build-up of oxidative stress by increasing serum superoxide dismutase, glutathion peroxidase, and reducing malonaldehyde concentration in hyperlipidemia rats. These findings provided scientific support for screening edible flowers as natural antioxidants and preventative treatments for oxidative stress-related diseases. PMID:28326000

Citrus bergamia Risso et Poiteau ("Bergamot") originated from the Mediterranean ecoregion (southern Italy, Calabria). Bergamot essential oil (BEO) is used in perfumes, cosmetics, and for stress reduction. Juice from C. bergamia has been used for hyperlipidemia. We evaluated literature published on C. bergamia clinical applications. Clinical trials on C. bergamia not combined with other substances, published in English, were searched. We selected ten articles, six describing BEO effects on stress, three reporting effects of polyphenolic fraction of C. bergamia juice in hyperlipidemia and the last describing BEO effects in chronic psoriasis. Clinical studies were analyzed following Consolidated Standards of Reporting Trials for herbal therapy. Studies were conducted on small sample sizes and not have high quality level. Analysis indicates that BEO aromatherapy could be safe and useful to reduce stress symptoms. One study suggests its potential supportive role in ultraviolet B therapy against psoriasis. Supplementation with polyphenols from bergamot juice reduces plasma lipids and improves lipoprotein profile in moderate hyperlipidemia. Effectiveness and safety of C. bergamia cannot be definitively drawn because of publication bias and low quality level of the majority of studies. Further large-scale trials with rigorous design are required to define the role of C. bergamia in clinical practice. Copyright © 2016 John Wiley & Sons, Ltd. Copyright © 2016 John Wiley & Sons, Ltd.

Dietary fructose but not starch is responsible for hyperlipidemia associated with copper deficiency in rats: effect of high-fat diet.

PubMed

Fields, M; Lewis, C G

1999-02-01

To test the hypothesis that copper deficiency in rats may be hyperlipidemic only when the diets consumed contain nutrients which contribute to blood lipids such as fructose and high fat. Weanling male Sprague Dawley rats were fed diets which contained either starch or fructose as their sole carbohydrate source. The diets were either inadequate (0.6 microg Cu/g) or adequate (6.0 microg Cu/g) in copper and contained either high (300 g/kg) or low (60 g/kg) fat. At the end of the 4th week the rats were killed. Livers were analyzed for copper content. Plasma was analyzed for cholesterol and triglyceride concentrations. High-fat diet did not increase blood lipids in rats fed a copper-deficient diet containing starch. In contrast, the combination of high-fat diet with fructose increased blood triglycerides and fructose with copper deficiency resulted in a significant increases in blood cholesterol. Hyperlipidemia of copper deficiency in rats is dependent on synergistic effects between dietary fructose and copper deficiency and fructose and amount of dietary fat. Hyperlipidemia does not develop if starch is the main source of dietary carbohydrate in a copper-deficient diet even if a high-fat diet is fed.

Phthalate exposure was reported to be associated with diabetes mellitus (DM) and cardiovascular disease (CVD). Yet, reported associations and the potential sex differences are inconsistent. We conducted a cross-sectional study involving 2330 participants in the Fall of 2012. Urinary metabolites of 10 phthalates were measured. The status of having DM and CVD-related outcomes were self-reported. In the overall study population, the logistic regression analyses showed that the urinary levels of mono-2-ethyl-5-oxohexyphthalate (MEOHP), mono-2-ethyl-5-hydroxyhexylphthalate(MEHHP) and mono-2-ethyl-5-carboxypentylphthalate (MECPP) were positively associated with DM. Higher urinary levels of monomethyl phthalate (MMP) and mono-2-carboxymethyl-hexyl phthalate (MCMHP) were associated with increased odds of hyperlipidemia, while mono-2-ethylhexylphthalate (MEHP) was significantly inverse-associated with hyperlipidemia. We did not observe significant associations for other CVD-related outcomes with phthalate metabolites. When stratifying by sex, MEHHP, MEOHP, MECPP, MCMHP and the micromolar sums of the oxidative metabolites of DEHP (ΣDEHP ox ) were all significantly related to DM in males, but not in females. No significant sex differences were found in CVD-related outcomes, except the sporadic associations between phthalates and hyperlipidemia. These findings highlight the importance of investigating the sex-specific relationship between phthalates exposure and DM.

Metabolic syndrome is one of the most important health issues worldwide. Obesity causes insulin resistance, hyperlipidemia, diabetes, and various diseases throughout the body. The liver phenotype, which is called nonalcoholic steatohepatitis (NASH), frequently progresses to hepatocellular carcinoma. We recently established a new animal model, Tsumura-Suzuki obese diabetic (TSOD) mice, which spontaneously exhibit obesity, diabetes, hyperlipidemia, and NASH with liver nodules. We examined the effects of coffee intake on various conditions of the metabolic syndrome using TSOD mice. The daily volume of coffee administered was limited so that it reflected the appropriate quantities consumed in humans. To clarify the effects of the specific components, animals were divided into two coffee-intake groups that included with and without caffeine. Coffee intake did not significantly affect obesity and hyperlipidemia in TSOD mice. In contrast, coffee intake caused various degrees of improvement in the pancreatic beta cell damage and steatohepatitis with liver carcinogenesis. Most of the effects were believed to be caused by a synergistic effect of caffeine with other components such as polyphenols. However, the antifibrotic effects of coffee appeared to be due to the polyphenols rather than the caffeine. A daily habit of drinking coffee could possibly play a role in the prevention of metabolic syndrome.

Melissa officinalis is a perennial herb from the Lamiaceae family which has shown to have modulating effects on serum lipid profile. The aim of the current study is to explore the effects of M. officinalis supplementation on serum biochemical parameters of patients with borderline hyperlipidemia. 58 hyperlipidemic patients were allocated randomly to 2 groups: first group received capsules containing 1000mg M. officinalis leaf powder (MO group), and the second group received placebo capsules (P group) 3 times per day for 2 months. Fasting blood glucose (FBG), HDL, LDL, Triglyceride, Creatinine and liver function enzymes including AST and ALT were evaluated before and after study. The mean of LDL in MO group significantly decreased compared with P group after the supplementation (P=0.02). Although the level of Cholesterol, FBG, HDL, Triglyceride, Creatinine and ALT did not show significant difference between two groups after 2 months (P≥0.05), the level of AST exhibited a significant difference between two groups (P=0.009). Our findings demonstrated that M. officinalis supplementation as a rich source of antioxidants and bioactive compounds can be effective in remission of LDL and AST levels in patients with borderline hyperlipidemia.

Chrysin (5,7-dihydroxyflavone) is a flavonoid, natural component of traditional medicinal herbs, present in honey, propolis and many plant extracts. The objective of this study was to investigate the hypolipidemic properties of chrysin on Triton WR-1339-induced hyperlipidemia in female C57BL/6 mice. Triton WR-1339 was administered intraperitoneally (400 mg/kg) to overnight-fasted mice to develop acute hyperlipidemia. Chrysin was administered orally (10 mg/kg) 30 min before Triton WR-1339. At 24 h after Triton WR-1339 injection, blood samples were collected to measure plasma lipid levels. The hepatic thiobarbituric acid reactive substances (TBARS), carbonyl content, non-protein sulfhydryl (NPSH) and ascorbic acid (AA) levels, as well as catalase (CAT) and superoxide dismutase (SOD) activity were recorded. Chrysin administration significantly decreased total cholesterol levels. In addition, it partially decreased non-high density lipoprotein-cholesterol and triglycerides levels in plasma of hyperlipidaemic mice. In addition chrysin administration prevented the increase on TBARS levels and prevented the decrease in SOD activity induced by Triton WR-1339. These findings indicated that chrysin was able to decrease plasma lipids concentration and that its antioxidant properties was, at least in part, involved in the hypolipidaemic action of chrysin.

To study the protective effects of Tianji soft capsule (TJSC) on blood lipids, internal antioxidant system and vascular endothelial system in hyperlipidemia rats. Seventy two healthy male rats were divided into six groups. The rats in control group were administered with ordinary diet. The rats in model group were fed with high cholesterol/lipid diet to induce hyperlipidemia. The rats in TJSC and CoQ10 groups were fed with high cholesterol/lipid diet, and treated with TJSC at different doses of 83 (low-dose group, L), 250 (middle-dose group, M), 750 (high-dose group, H) mg/kg, and CoQ10 at the dose of 83 mg/kg, respectively. All animals were put to death after four weeks, effects on lipid level; antioxidant system and endothelial system were evaluated through detection of total cholesterol (TC), triglyceride (TG), very low density lipoprotein (VLDL), atherogenic index (AI), malondidehyde (MDA) and plasma endothelin (ET), HDL/TC ratio, activities of superoxide dismutase (SOD) and nitric oxide (NO). Compared with model group, serum TC, TG, VLDL, AI, MDA and ET reduced and the HDL/TC ratio increased, meanwhile activities of SOD and NO were enhanced. TJSC can regulate the lipid metabolism, enhance antioxidant system and protect the vascular endothelia system in hyperlipiemic rats.

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

We evaluated the effects of cinnamon polyphenol extract on hepatic transcription factors expressions including SREBP-1c and LXR- α in rats fed high fat diet (HFD). Twenty-eight Wistar rats were allocated into four groups: (i) normal control: animals fed with normal chow; (ii) cinnamon: animals supplemented with cinnamon polyphenol; (iii) HFD: animals fed a high-fat diet; and (iv) HFD + cinnamon: animals fed a high-fat diet and treated with cinnamon polyphenol. Obesity was linked to hyperglycemia, hyperlipidemia, and oxidative stress as imitated by elevated serum glucose, lipid profile, and serum and liver malondialdehyde (MDA) concentrations. Cinnamon polyphenol decreased body weight, visceral fat, liver weight and serum glucose and insulin concentrations, liver antioxidant enzymes, and lipid profile ( P < 0.05) and reduced serum and liver MDA concentration compared to HFD rats ( P < 0.05). Cinnamon polyphenol also suppressed the hepatic SREBP-1c, LXR- α , ACLY, FAS, and NF- κ B p65 expressions and enhanced the PPAR- α , IRS-1, Nrf2, and HO-1 expressions in the HFD rat livers ( P < 0.05). In conclusion, cinnamon polyphenol reduces the hyperlipidemia, inflammation, and oxidative stress through activating transcription factors and antioxidative defense signaling pathway in HFD rat liver.

Twenty-eight Wistar rats were allocated into four groups: (i) normal control: animals fed with normal chow; (ii) cinnamon: animals supplemented with cinnamon polyphenol; (iii) HFD: animals fed a high-fat diet; and (iv) HFD + cinnamon: animals fed a high-fat diet and treated with cinnamon polyphenol. Obesity was linked to hyperglycemia, hyperlipidemia, and oxidative stress as imitated by elevated serum glucose, lipid profile, and serum and liver malondialdehyde (MDA) concentrations. Cinnamon polyphenol decreased body weight, visceral fat, liver weight and serum glucose and insulin concentrations, liver antioxidant enzymes, and lipid profile (P < 0.05) and reduced serum and liver MDA concentration compared to HFD rats (P < 0.05). Cinnamon polyphenol also suppressed the hepatic SREBP-1c, LXR-α, ACLY, FAS, and NF-κB p65 expressions and enhanced the PPAR-α, IRS-1, Nrf2, and HO-1 expressions in the HFD rat livers (P < 0.05). In conclusion, cinnamon polyphenol reduces the hyperlipidemia, inflammation, and oxidative stress through activating transcription factors and antioxidative defense signaling pathway in HFD rat liver.

Hyperlipidemia is a major independent risk factor for atherosclerosis. Seeking natural compounds in medicinal plants capable of reducing blood fat and studying their mechanisms of action has been the focus of research in recent years. The aim of the present study was to analyze the mechanisms of apigenin in regulating cholesterol metabolism and protecting blood vessels, and to provide a theoretical basis for the clinical application of apigenin. The mouse model of hyperlipidemia was established to verify the efficacy of apigenin in improving hyperlipidemia and to observe the mechanism of action of apigenin in reducing cholesterol content. In vitro cell experiments were conducted to evaluate the role of apigenin in mediating reverse cholesterol transport. Additionally, H2O2-injured human umbilical venous endothelial cells (EA.hy926 cells) were used for further study on the roles of apigenin in resisting oxidization and protecting vascular endothelial cells. Apigenin significantly regulated blood fat, reduced animal weight, and reduced total cholesterol (P=0.024), triglyceride (P=0.031) and low-density lipoprotein cholesterol (P=0.014) in the serum of the high-fat diet mice. Apigenin improved the blood lipid metabolism of the hyper-lipidemia model mice. Body weight and serum cholesterol content increased abnormally (P=0.003) as a consequence of high-fat diet. Apigenin increased the activity of superoxide dismutase in EA.hy926 cells (P=0.043) and increased the amount of nitric oxide secreted by the cells (P=0.038). Apigenin also inhibited the proliferation of vascular smooth muscle cells in a dose-dependent manner (P=0.036). In conclusion, apigenin can regulate cholesterol metabolism in vivo and plays a role in reducing the level of blood fat by promoting cholesterol absorption and conversion, and accelerating reverse cholesterol transport. Apigenin also has a role in resisting oxidization and protecting blood vessels. PMID:28565758

Both postprandial hyperlipidemia and hyperinsulinemia have been thought to play an important role in the development of atherosclerosis, and to be a potent risk factor for cardiovascular event. To examine effects of glycemic state on postprandial hyperlipidemia and hyperinsulinemia in patients with coronary artery disease (CAD), a total of 112 consecutive male pati ents with angiographically confirmed CAD were loaded with a high-fat and high-glucose test meal. CAD patients were divided into three groups as "non-diabetic", "prediabetic", and "diabetic" CAD groups. The serum triglyceride (TG) and remnant-like particle cholesterol (RLP-C) levels at the 6th hour in diabetic CAD group showed significantly higher than non-diabetic CAD group, and the incremental area under the curves (iAUCs) of these levels in diabetic CAD group were significantly greater than non-diabetic CAD group (TG, P = 0.0194; RLP-C, P = 0.0219). There were no significant differences in the iAUCs of TG or RLP-C between prediabetic and non-diabetic CAD group. The AUCs of plasma insulin levels or insulin resistance index (IRI): (AUCs of insulin) × (AUCs of glucose) as the insulin resistance marker were greater in diabetic CAD group than non-diabetic CAD group (insulin, P = 0.0373; IRI, P = 0.0228). The AUCs of serum TG or RLP-C levels showed a correlation with the AUCs of plasma insulin (AUC-TG, r = 0.5437, P < 0.0001; AUC-RLP-C, r = 0.6847, P < 0.0001), and they correlated well with the insulin resistance index (AUC-TG, r = 0.7724, P < 0.0001; AUC-RLP-C, r = 0.7645, P < 0.0001). We found that the insulin resistance showed a close relationship with postprandial hyperlipidemia in CAD patients. Diabetic, but not prediabetic state, may be a risk for postprandial impaired lipid metabolism in CAD patients.

To evaluate the efficacy and safety of using Jiangzhi Tongluo Soft Capsule (JTSC) combined with Atorvastatin Calcium Tablet (ACT) or ACT alone in treatment of combined hyperlipidemia. A randomized, double blinded, parallel control, and multi-center clinical research design was adopted. Totally 138 combined hyperlipidemia patients were randomly assigned to the combined treatment group (A) and the atorvastatin treatment group (B) by random digit table, 69 in each group. All patients took ACT 20 mg per day. Patients in the A group took JTSC 100 mg each time, 3 times per day. Those in the B group took JTSC simulated agent, 100 mg each time, 3 times per day. The treatment period for all was 8 weeks. Serum levels of triglyceride (TG), total cholesterol (TC), low density lipoprotein cholesterol (LDL-C), and high density lipoprotein cholesterol (HDL-C) were observed before treatment, at week 4 and 8 after treatment; and safety was assessed as well. At week 4 and 8 after treatment serum TG decreased by 26.69% and 33.29% respectively in the A group (both P < 0.01), while it was decreased by 25.7% and 22.98% respectively in the B group (both P < 0.01). At week 8 decreased serum TG was obviously higher in the A group than in the B group (P < 0.05). Compared with before treatment, serum levels of LDL-C and TC levels decreased significantly in the two groups (all P < 0.01). There was no statistical difference in the drop-out value and the drop-out rate of serum LDL-C and TC levels (P > 0.05). At week 8 the serum HDL-C level showed an increasing tendency in the two groups. No obvious increase in peptase or creatase occurred in the two groups after treatment. JTSC combined with ACT could lower the serum TG level of combined hyperlipidemia patients with safety.

Due to the development of antiretroviral therapy (ART), HIV/AIDS is now regarded as a treatable chronic disease. Chinese herbal medicine (CHM) is a type of complementary and alternative medicine (CAM) that has been widely applied in the healthcare system in Taiwan. The aim of this study was to investigate the frequency of use and patterns of prescription for the CHM-based treatment of HIV-infected patients and to assess the long-term effects of CHM on hyperlipidemia and cardiovascular disease events in these patients. We identified 21,846 HIV-infected patients (ICD-9-CM: 042-044, 079, and V08 codes). Of these, 1083 and 2166 patients who used CHM and were non-users, respectively, were matched for age, gender, and ART use before CHM. The chi-squared test, Cox proportional hazard model, Kaplan-Meier method, and the log-rank test were used for comparisons between these two groups. CHM users had a lower risk of hyperlipidemia compared with non-users after adjusting for comorbidities by using a multivariate Cox proportional hazard model (P = 0.0011; HR: 0.66, 95% CI: 0.52-0.85). In addition, the CHM users had a lower risk of cardiovascular disease compared with non-users after adjusting for comorbidities (P = 0.0004; HR: 0.67, 95% CI: 0.53-0.83). The 10-year cumulative incidences of hyperlipidemia and cardiovascular disease were lower in the CHM group (P < 0.0001 for both, log rank test). Among the 12 most commonly used CHMs in these patients, Jia-Wei-Xiao-Yao-San (JWXYS) (46.1%), Ge-Gen-Tang (GGT) (40.6%), and Yin-Qiao-San (YQS) (38.0%) were the most common herbal formulas used. Huang-Qin (HQin) (44.6%), Yan-Hu-Suo (YHS) (40.5%), and Jie-Geng (JG) (39.5%) were the most commonly used single herbs. A CHM network analysis showed that JG was the core CHM in one cluster, and BM, MXSGT, and HQin were important CHMs in that cluster. In the other cluster, YHS was the core CHM, and SYGCT and JWXYS were important CHMs. CHM as adjunctive therapy may reduce hyperlipidemia and the risk for cardiovascular disease in HIV-infected patients. The list of the comprehensive herbal medicines that the patients used might be useful in further scientific investigations or therapeutic interventions for preventing atherosclerosis among HIV-infected patients.

Orozco, Pilar

Epidemiological studies have reported that women with osteoporosis present an increased risk of cardiovascular events and that lipid lowering therapy (statins) could be associated with a decreased risk of fracture. We investigated whether women with atherogenic lipid profile have lower lumbar and femoral bone mineral density (BMD) and higher prevalence of osteopenia than those with normal lipid levels. The study included 52 overweight early postmenopausal women, with no history of hormone replacement therapy, or any current or past pathology or treatment that could alter bone or lipid metabolism. Atherogenic lipid profile or hyperlipidemia was defined as hypercholesterolemia (> or = 240 mg/dl) or high low-density lipoprotein cholesterol (high-LDLc > or = 160 mg/dl) or high lipoprotein (a) [high-Lp (a) > or =25 mg/dl], and low-BMD as t-score <-1 SD at lumbar o femoral site. The results show that women with hyperlipidemia had lower mean-adjusted BMD (mean+/-SEM) at lumbar (0.865+/-0.020 vs. 0.958+/-0.028 g/cm2, p = 0.007) and femoral neck (0.712+/-0.015 vs. 0.796+/-0.021, p = 0.004 g/cm2) than those with normal lipid levels. Hypercholesterolemia group had higher prevalence of low-BMD at lumbar spine (82.6% vs. 55.2%, p = 0.04, OR: 3.8; 95% CI: 1.04-14.2) and femoral neck (65.2% vs. 37.9%, p = 0.05, OR: 3.1; 95% CI: 0.98-9.6). The high-LDLc group had also higher prevalence low-BMD at femoral neck (75% vs. 39%, p = 0.01, OR: 4.7; 95% CI: 1.26-17.5), and the high-Lp (a) group at lumbar spine (87% vs. 51.7% p = 0.007, OR: 6.2; 95% CI: 1.5-25.6). Women with hyperlipidemia had higher prevalence of low BMD at lumbar spine (81.8% vs. 42.1%, p = 0.003, OR: 6.2; 95% CI: 1.7-22) and femoral neck (60.6% vs. 31.6%, p = 0.04, OR: 3.3; 95% CI: 1.01-11.0). In conclusion, early postmenopausal women with atherogenic lipid profile, defined as cholesterol > or =240 mg/dl or LDLc > or = 160 mg/dl or Lp(a) > or = 25 mg/dl have lower lumbar and femoral BMD and have an increased risk of osteopenia than those with normal lipid profile, suggesting that hyperlipidemia could be associated with osteoporosis and bone status should be evaluated in women with hyperlipidemia.

AIM: To investigate the prevalence of fatty liver discovered upon physical examination of Chinese patients and determine the associated clinical characteristics. METHODS: A total of 3433 consecutive patients who received physical examinations at the Huangpu Division of the First Affiliated Hospital at Sun Yat-sen University in Guangzhou, China from June 2010 to December 2010 were retrospectively enrolled in the study. Results of biochemical tests, abdominal ultrasound, electrocardiography, and chest X-ray were collected. The diagnosis of fatty liver was made if a patient met any two of the three following ultrasonic criteria: (1) liver and kidney echo discrepancy and presence of an increased liver echogenicity (bright); (2) unclear intrahepatic duct structure; and (3) liver far field echo decay. RESULTS: The study population consisted of 2201 males and 1232 females, with a mean age of 37.4 ± 12.8 years. When all 3433 patients were considered, the overall prevalence of hyperlipidemia was 38.1%, of fatty liver was 26.0%, of increased alanine aminotransferase (ALT) and/or aspartate aminotransferase (AST) levels was 11.9%, of gallstone was 11.4%, of hyperglycemia was 7.3%, of hypertension was 7.1%, and of hyperuricemia was 6.2%. Of the 2605 patients who completed the abdominal ultrasonography exam, 677 (26.0%) were diagnosed with fatty liver and the prevalence was higher in males (32.5% vs females: 15.3%, P < 0.001). The overall prevalence of fatty liver increased with age, with the peak prevalence (39.5%) found in the 60 to 70-year-old age group. Among patients between the ages of 18 to 50-year-old, the prevalence of fatty liver was significantly higher in males (20.2% vs females: 8.7%, P < 0.001); the difference in prevalence between the two sexes in patients > 50-year-old did not reach statistical significance. Only 430 of the patients diagnosed with fatty liver had complete information; among those, increased ALT and/or AST levels were detected in only 30%, with all disturbances being mild or moderate. In these 430 patients, the overall prevalence of hypertriglyceridemia was 31.4%, of mixed type hyperlipidemia was 20.9%, of hypercholesterolemia was 12.3%, of hyperglycemia was 17.6%, of hypertension was 16.0%, of hyperuricemia was 15.3%, and of gallstone was 14.4%. Again, the prevalences of hypertriglyceridemia and hyperuricemia were higher in males (hypertriglyceridemia, 36.0% vs females: 12.0%, P < 0.05; hyperuricemia, 17.3% vs females: 7.2%, P < 0.05); in contrast, however, the prevalences of mixed type hyperlipidemia and hypercholesterolemia was higher in females (mixed type hyperlipidemia, 18.7% vs females: 30.1%, P < 0.05, hypercholesterolemia, 9.5% vs females: 24.1%, P < 0.05). Finally, comparison of the fatty liver group to the non-fatty liver group showed that prevalences of hyperlipidemia, hyperglycemia, hypertension, and hyperuricemia were higher in the former (all P < 0.01). CONCLUSION: A high prevalence of fatty liver is detected upon physical examination in Guangzhou, and the primary associated clinical findings are hyperlipidemia, hyperglycemia, hypertension, and hyperuricemia.

Modifying Risk Factors in the Management of Erectile Dysfunction: A Review

PubMed Central

DeLay, Kenneth J; Haney, Nora

2016-01-01

Erectile dysfunction (ED) is prevalent among men and its presence is often an indicator of systemic disease. Risk factors for ED include cardiovascular disease, hypertension, diabetes mellitus (DM), tobacco use, hyperlipidemia, hypogonadism, lower urinary tract symptoms, metabolic syndrome, and depression. Addressing the modifiable risk factors frequently improves a patient's overall health and increases lifespan. The literature suggests that smoking cessation, treatment of hyperlipidemia, and increasing physical activity will improve erectile function in many patients. How the treatment of DM, depression, and hypogonadism impacts erectile function is less clear. Clinicians need to be aware that certain antihypertensive agents can adversely impact erectile function. The treatment of men with ED needs to address the underlying risk factors to ameliorate the disease process. PMID:27574592

The main objective of this study was to investigate the ameliorative effects of aspirin eugenol ester (AEE) in hyperlipidemic rat. After five-week oral administration of AEE in high fat diet (HFD)-induced hyperlipidemic rats, the impact of AEE on plasma and urine metabonomics was investigated to explore the underlying mechanism by UPLC-Q-TOF/MS analysis. Blood lipid levels and histopathological changes of liver, stomach and duodenum were also evaluated after AEE treatment. Without obvious gastrointestinal (GI) side effects, AEE significantly relieved fatty degeneration of liver and reduced triglyceride (TG), low density lipoprotein (LDL) and total cholesterol (TCH) (P<0.01). Clear separations of metabolic profiles were observed among control, model and AEE groups by using principal component analysis (PCA) and orthogonal partial least-squares-discriminate analysis (OPLS-DA). 16 endogenous metabolites in plasma and 18 endogenous metabolites in urine involved in glycerophospholipid metabolism, fatty acid metabolism, fatty acid beta-oxidation, amino acid metabolism, TCA cycle, sphingolipid metabolism, gut microflora and pyrimidine metabolism were considered as potential biomarkers of hyperlipidemia and be regulated by AEE administration. It might be concluded that AEE was a promising drug candidate for hyperlipidemia treatment. These findings could contribute to the understanding of action mechanisms of AEE and provide evidence for further studies. Copyright © 2017 Elsevier Inc. All rights reserved.

Squalene synthase (SQS), a key downstream enzyme involved in the cholesterol biosynthetic pathway, plays an important role in treating hyperlipidemia. Compared to statins, SQS inhibitors have shown a very significant lipid-lowering effect and do not cause myotoxicity. Thus, the paper aims to discover potential SQS inhibitors from Traditional Chinese Medicine (TCM) by the combination of molecular modeling methods and biological assays. In this study, cynarin was selected as a potential SQS inhibitor candidate compound based on its pharmacophoric properties, molecular docking studies and molecular dynamics (MD) simulations. Cynarin could form hydrophobic interactions with PHE54, LEU211, LEU183 and PRO292, which are regarded as important interactions for the SQS inhibitors. In addition, the lipid-lowering effect of cynarin was tested in sodium oleate-induced HepG2 cells by decreasing the lipidemic parameter triglyceride (TG) level by 22.50%. Finally. cynarin was reversely screened against other anti-hyperlipidemia targets which existed in HepG2 cells and cynarin was unable to map with the pharmacophore of these targets, which indicated that the lipid-lowering effects of cynarin might be due to the inhibition of SQS. This study discovered cynarin is a potential SQS inhibitor from TCM, which could be further clinically explored for the treatment of hyperlipidemia.

Sedentary behavior is considered an independent cause of cardio-metabolic diseases, regardless of physical activity level and obesity. Few studies have reported the association between leisure sedentary time and cardio-vascular diseases in terms of occupation. We performed a cross-sectional study using data from the Korean Community Health Survey (KCHS) for 240,086 participants assessed in 2011 and 2013. Occupation was categorized into four groups: farmer or fisherman, laborer, and soldier (Group I); service worker, salesperson, technician, mechanic, production worker, and engineer (Group II); manager, expert, specialist, and clerk (Group III); and unemployed (Group IV). Leisure sedentary time was divided into five groups: 0 h, 1 h, 2 h, 3 h, and 4+ h. The association between leisure sedentary time on weekdays and hypertension/diabetes mellitus/hyperlipidemia for different occupations was analyzed using simple and multiple logistic regression analyses with complex sampling. In Groups I, II and III, no length of sedentary time was associated with hypertension, and only 3 h or 4+ h of sedentary time was associated with diabetes mellitus and hyperlipidemia. Group IV showed a significant association with hypertension and diabetes mellitus for the 2 h, 3 h, and 4+ h sedentary times. The unemployed are more susceptible than other occupation groups to cardio-metabolic diseases when leisure time is sedentary.

Chronic hyperlipemia increases the incidence of vascular endothelial dysfunction and can even induce cardiovascular disease. Sea buckthorn contains a host of bioactives such as flavonoids and polyphenols that can prevent the development of cardiovascular disease. The current study isolated active ingredients, polyphenols, from sea buckthorn berries (SVP) and orally administered SVP at a dose of 7-28 mg/kg. This treatment significantly reduced serum lipids, it enhanced the activity of antioxidant enzymes, and it decreased the level of serum TNF-α and IL-6. SVP also alleviate vascular impairment by decreasing the expression of eNOS, ICAM-1, and LOX-1 mRNA and proteins in aortas of rats with hyperlipidemia. Based on these findings, SVP has antioxidant action and it protects endothelium.

Hyperlipidemia (HLP) is the No.1 risk factor for patients with atherosclerosis (AS) and is directly related to the occurrence of coronary artery disease (CAD) and cerebrovascular disease. Therefore, prevention and treatment of AS is of great importance and of practical significance in controlling the incidence and mortality of CAD. With its peculiar syndrome-dependent therapy, traditional Chinese medicine (TCM) has accumulated abundant practical experiences in this field and good clinical effects have been achieved. Chinese herbal medicine, with its particularly unique advantages and high potentials yet to be tapped, displays its huge strength in HLP prevention and treatment. The progress of studies concerning prevention and treatment of HLP by Chinese herbal medicines, in the form of monomers or compound recipes, is reviewed in this paper.

To assist in the long-term health management of residents and evaluate health impacts after the Tokyo Electric Power Company's Fukushima Daiichi Nuclear Power Plant accident in Fukushima Prefecture, the Fukushima prefectural government decided to conduct the Fukushima Health Management Survey. This report describes the results for residents aged 16 years or older who received the health check examinations and evaluates the data obtained from 2011 and 2012. The target group consisted of residents aged 16 years or older who had lived in the evacuation zone. The health check examinations were performed on receipt of an application for a health check examination from any of the residents. The examinations, including measurements of height, weight, abdominal circumference/body mass index (BMI), blood pressure, biochemical laboratory findings, and peripheral blood findings, were performed as required. 1) A total of 56,399 (30.9%) and 47,009 (25.4%) residents aged 16 years or older received health checks in 2011 and 2012, respectively. 2) In both years, a number of male and female residents in the 16-39 year age group were found to suffer obesity, hyperlipidemia, hyperuricemia, or liver dysfunction, and the prevalence of obesity and hyperlipidemia among residents increased with age. Furthermore, the proportion of residents with hypertension, glucose metabolic abnormalities or renal dysfunction was higher in those aged 40 years or older. 3) The frequencies of obesity, hypertension and hyperlipidemia among residents in 2012 were lower than those in 2011. However, the prevalence of liver dysfunction, hyperuricemia, glucose metabolic abnormalities and renal dysfunction among residents was higher in 2012 than in 2011. These results suggested the number of residents who had lived in the evacuation zone with obesity, hyperlipidemia, hyperuricemia, liver dysfunction, hypertension, glucose metabolic abnormalities, or renal dysfunction increased with age in all age groups. Therefore, we think that it is necessary to continue with health check examinations for these residents in order to ameliorate lifestyle-related disease.

Hyperlipidemia is a risk factor for initiation and progression of diabetic nephropathy but the metabolic pathways altered in the diabetic kidney in a context of hyperlipidemia remain incompletely described. Assuming that changes in urine composition reflect the alteration of renal metabolism and function, we analyzed the urine metabolite composition of diabetic (streptozotocin-treatment) and control (non diabetic) ApoE−/− mice fed a high cholesterol diet using targeted quantitative metabolomics.

After adjustment to urine creatinine, the abundance of 52 urine metabolites was significantly different in diabetic mice compared to control.

Hyperlipidemia is one of the famous disorders that can lead to atherosclerosis. Garlic has been considered as one of the blood lipids lowering agents for ages, and various studies have been carried out, some of them confirmed this effect of garlic and some did not. The aim of this study was to evaluate the effect of raw garlic consumption on human blood biochemical factors in hyperlipidemic individuals. This clinical trial was conducted on 30 volunteer individuals with blood cholesterol higher than 245 mg/dl. Fasting blood samples were collected for biochemical tests. The volunteers consumed 5 g raw garlic twice a day for 42 days. Second fasting blood samples were collected and the individuals did not use any kind of garlic for next 42 days. After that, the third fasting blood samples were collected and the biochemical factors were measured. After 42 days of garlic consumption the mean of blood total cholesterol (p<0.001) triglycerides (p<0.01) and FBS (p<0.01) were reduced significantly, but HDL-C was increased (p<0.001) significantly. Following 42 days of no garlic consumption total cholesterol (p<0.001), triglycerides and FBS (p<0.05) were significantly increased and HDL-C (p<0.01) decreased. Garlic consumption alone can decrease serum lipids, but it cannot be used as the main therapeutic agent for hyperlipidemia. Garlic can be used in mild hyperlipidemia or when the patients cannot tolerate the chemical drugs.

Recently, many reports have shown that Averrhoa carambola L. (Oxalidaceae) juice (EACJ) could reduce blood glucose in humans. However, its mechanisms have not been well explored; therefore, our study aimed to investigate the beneficial effects of EACJ on hyperglycemia, hyperlipidemia and renal injury in streptozotocin (STZ)-induced diabetic mice. Those mice were injected with STZ via the tail vein (120 mg/kg body weight) and were identified as diabetic mice when the level of blood glucose was ≥ 11.1 mmol/L. Those mice were intragastriced gavage with saline, EACJ (25, 50, 100 g/kg body weight/d) and metformin (320 mg/kg body weight/d) for 21 days. The fasting blood glucose (FBG), free fatty acids (FFA), total cholesterol (TC), triglycerides (TG), Scr (CREA) and blood urea nitrogen (BUN) were significantly decreased, while the sorbitol dehydrogenase (SDH), Cyclic Adenosine monophosphate (cAMP), malondialdehyde (MDA), superoxide dismutase (SOD), and insulin were elevated. Diabetes-dependent alterations in the kidney, such as glomerular hypertrophy, thicken and tubular basement membrane, were improved after 21 days of EACJ treatment. Hyperglycemia, renal formation and the expressions of related proteins such as connective tissue growth factor (CTGF) and transforming growth factor beta 1 (TGF-β1) were markedly decreased by EACJ. These results indicate that EACJ treatment decrease hyperglycemia, hyperlipidemia and inhibit the progression of diabetic nephropathy (DN), which may be linked to regulating several pharmacological targets for treating or preventing DN.

Inflammation and endothelial dysfunction is implicated in the atherosclerosis initiation and progression in the setting of hyperlipidemia. Colchicine is a potent anti-inflammatory agent and whether colchicine combined with atorvastatin has synergistic effects on inflammation amelioration and endothelial function improvement is unknown. Hyperlipidemic rat model was produced by high-fat and high-cholesterol diet for 6 weeks. Rats with normal diet were served as shame group. In hyperlipidemic group, normal saline, atorvastatin (10 mg/kg body weight/day), colchicines (0.5 mg/kg body weight/day), or atorvastatin combined with colchicines (same dosages) were prescribed for 2 weeks. Serum levels of lipid profile, C-reactive protein (CRP), liver enzyme, lipoprotein associated phospholipase A2 (Lp-PLA2) and nitric oxide (NO) production were serially assessed. Before the beginning of the study, all laboratory variables were comparable among each group. After 6 weeks of hyperlipidemic model production, serum levels of cholesterols, CRP and Lp-PLA2 were significantly increased when compared to sham group, whereas NO production was reduced. With 2 weeks of colchicine therapy, serum levels of CRP and Lp-PLA2 were decreased and NO production was enhanced in the colchicine group in a lipid-lowering independent manner. Added colchicine into atorvastatin therapy further improved NO production and decreased CRP and Lp-PLA2 levels, indicating a potential synergism of colchicine and atorvastatin. Colchicine combined with atorvastatin may have stronger protective effects on improving endothelial function and ameliorating inflammation in rats with hyperlipidemia.

Hyperlipidemia is a known cause of coronary vascular diseases, which is a major cause of death in many parts of the world. Targeting several pathways that lead to increase in lipid profiles is of great potential to control diseases. 1H-indole-2-carboxamide derivatives were tested for their hypolipidemic activity at the molecular level in comparison with bezafibrate. The gene expression profiles of lipoprotein signaling and cholesterol metabolism and fatty acid metabolism PCR arrays were determined in rats with acute hyperlipidemia induced by Triton WR1339. Lipid profiles of serum from treated rats showed significant hypolipidemic effect by the compounds. Several genes of potential interest were reported to be overexpressed by Triton WR1339 including Apoc3, Apob, Hmgcs2, Apoa1, Apoe, Apof, acsl1, and Decr1. Most of the overexpressed genes were downregulated by N-(3-Benzoylphenyl)-1H-Indole-2-Carboxamide with significant decreases in Apoc3, Apob, Acaa2, Acsl1, and Slc247a5 gene expression levels. N-(4-Benzoylphenyl)-1H-Indole-2-Carboxamide and bezafibrate did not significantly affect the gene expression levels which were increased with acute hyperlipidemia induced by Triton WR1339. In conclusion, gene expression profiling identified the possible mechanism in which Triton WR1339 induces its acute hyperlipidemic effect which was reversed by the use of N-(3-Benzoylphenyl)-1H-Indole-2-Carboxamide.

Vitamin A status regulates obesity development, hyperlipidemia, and hepatic lipogenic gene expression in Zucker fatty (ZF) rats. The development of hyperlipidemia in acne patients treated with retinoic acid (RA) has been attributed to the induction of apolipoprotein C-III expression. To understand the role of retinoids in the development of hyperlipidemia in ZF rats, the expression levels of several selected RA-responsive genes in the liver and isolated hepatocytes from Zucker lean (ZL) and ZF rats were compared using real-time PCR. The Rarb and Srebp-1c mRNA levels are higher in the liver and isolated hepatocytes from ZF than ZL rats. The Apoc3 mRNA level is only higher in the isolated hepatocytes from ZF than ZL rats. To determine whether dynamic RA production acutely regulates Apoc3 expression, its mRNA levels in response to retinoid treatments or adenovirus-mediated overexpression of hepatocyte nuclear factor 4 alpha (HNF4α) and chicken ovalbumin upstream-transcription factor II (COUP-TFII) were analyzed. Retinoid treatments for 2-6 h did not induce the expression of Apoc3 mRNA. The overexpression of HNF4α or COUP-TFII induced or inhibited Apoc3 expression, respectively. We conclude that short-term retinoid treatments could not induce Apoc3 mRNA expression, which is regulated by HNF4α and COUP-TFII in hepatocytes.

Background: Normalization of hyperglycemia, hyperlipidemia, and oxidative stress is an important objective in preventing diabetes-induced cardiac dysfunction. Objective: This study was undertaken to examine the effects of gallic acid in myocardial dysfunctions associated with type-1 diabetes. Materials and Methods: Diabetes was induced by single intravenous injection of streptozotocin (STZ, 50 mg/kg i.v.). Gallic acid was administered daily at three different doses (100, 50, and 25 mg/kg p.o.) for 8 weeks at the end of which blood samples were collected and analyzed for various biochemical parameters. Results: Injection of STZ produced significant loss of body weight (BW), polyphagia, polydypsia, hyperglycemia, hypoinsulinemia, hyperlipidemia, hypertension, bradycardia, and myocardial functional alterations. Treatment with gallic acid significantly lowered fasting glucose, the AUCglucose level in a dose-dependent manner; however, the insulin level was not increased significantly at same the dose and prevented loss of BW, polyphagia, and polydypsia in diabetic rats. It also prevented STZ-induced hyperlipidemia, hypertension, bradycardia, structural alterations in cardiac tissue such as increase in force of contraction, left ventricular weight to body weight ratio, collagen content, protein content, serum lactate dehydrogenase, and creatinine kinase levels in a dose-dependent manner. Further, treatment also produced reduction in lipid peroxidation and increase in antioxidant parameters in heart of diabetic rats. Conclusion: The results of this study suggest that gallic acid to be beneficial for the treatment of myocardial damage associated with type-1 diabetes. PMID:22224046

Pontine infarction induced by injury of the perforating branch of the basilar artery after blunt head impact: case report.

PubMed

A 77-year-old male pedestrian was hit by a car. On admission, he had disturbance of consciousness and left hemiplegia. Computed tomography (CT) indicated only left frontal subcutaneous hematoma and minor hemorrhage in the left frontal lobe, suggesting axonal injury. CT on hospital day 2 revealed a low density area in the right paramedian pons, but CT angiography showed no dissection or occlusion of the vertebrobasilar artery. The diagnosis was pontine infarction resulting from shearing force injury to the paramedian branch of the basilar artery. He was transferred to another hospital for rehabilitation without improvement of symptoms on hospital day 51. Paramedian pontine infarction tends to occur in patients with risk factors for arteriosclerosis, including hypertension, diabetes mellitus, hyperlipidemia, or smoking. The present elderly patient had hypertension and hyperlipidemia, so arteriosclerosis in the paramedian branch may have contributed to his susceptibility to such injury.

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.

Obstructive sleep apnea, a syndrome leading to recurrent intermittent hypoxia (IH), has been associated previously with hypercholesterolemia, independent of underlying obesity. We examined the effects of experimentally induced IH on serum lipid levels and pathways of lipid metabolism in the absence and presence of obesity. Lean C57BL/6J mice and leptin-deficient obese C57BL/6J-Lep(ob) mice were exposed to IH for five days to determine changes in serum lipid profile, liver lipid content, and expression of key hepatic genes of lipid metabolism. In lean mice, exposure to IH increased fasting serum levels of total cholesterol, high-density lipoprotein (HDL) cholesterol, phospholipids (PLs), and triglycerides (TGs), as well as liver TG content. These changes were not observed in obese mice, which had hyperlipidemia and fatty liver at baseline. In lean mice, IH increased sterol regulatory element binding protein 1 (SREBP-1) levels in the liver, increased mRNA and protein levels of stearoyl-coenzyme A desaturase 1 (SCD-1), an important gene of TG and PL biosynthesis controlled by SREBP-1, and increased monounsaturated fatty acid content in serum, which indicated augmented SCD-1 activity. In addition, in lean mice, IH decreased protein levels of scavenger receptor B1, regulating uptake of cholesterol esters and HDL by the liver. We conclude that exposure to IH for five days increases serum cholesterol and PL levels, upregulates pathways of TG and PL biosynthesis, and inhibits pathways of cholesterol uptake in the liver in the lean state but does not exacerbate the pre-existing hyperlipidemia and metabolic disturbances in leptin-deficient obesity.

To assess the association between hyperuricemia and different neuropsychiatric manifestations and stroke risk factors in systematic lupus erythematosus (SLE) patients. This study was conducted on 204 SLE patients who were admitted to a tertiary referral center. A standardized questionnaire was completed for all the participants and the medical records were reviewed regarding the occurrence of arterial or venous thrombotic events, stroke, seizure, depression, headache, psychosis, and peripheral neuropathy. In addition blood samples were drawn to obtain serum uric acid, triglyceride (TG), high-density lipoprotein (HDL) cholesterol, low-density lipoprotein (LDL) cholesterol, and total cholesterol levels. Hyperuricemia (serum uric acid ≥ 6mg/dl for women and ≥ 7mg/dl for men) was detected in 16.1% of SLE patients and was significantly associated with the occurrence of stroke (OR, 2.38; 95%CI, 1.2-7.24), and peripheral neuropathy (OR, 3.49; 95% CI, 1.52-12.23), independent of hypertension and hyperlipidemia. Hyperuricemia was also significantly associated with hypertension (OR, 7.76; 95% CI, 2.72-15.76), hyperlipidemia (OR, 5.05; 95% CI, 1.59-11.32), and history of arterial thrombosis (OR, 4.95; 95% CI, 1.98-15.34), independent of age and body mass index. Hyperuricemia in SLE patients is independently associated with the occurrence of stroke and peripheral neuropathy. It is also independently associated with hypertension, hyperlipidemia, and history of arterial thrombosis, which are the major stroke and myocardial infarction risk factors in SLE patients.

To investigate the possible involvement of betel-quid chewing in adipocyte dysfunction, we determined the effects of arecoline, a major alkaloid in areca nuts, on adipogenic differentiation (adipogenesis), lipolysis, and glucose uptake by fat cells. Using mouse 3T3-L1 preadipocytes, we showed that arecoline inhibited adipogenesis as determined by oil droplet formation and adipogenic marker gene expression. The effects of arecoline on lipolysis of differentiated 3T3-L1 adipocytes were determined by the glycerol release assay, indicating that arecoline induced lipolysis in an adenylyl cyclase-dependent manner. The diabetogenic effects of arecoline on differentiated 3T3-L1 adipocytes were evaluated by the glucose uptake assay, revealing thatmore » {>=} 300 {mu}M arecoline significantly attenuated insulin-induced glucose uptake; however, no marked effect on basal glucose uptake was detected. Moreover, using 94 subjects that were randomly selected from a health check-up, we determined the association of betel-quid chewing with hyperlipidemia and its related risk factors. Hyperlipidemia frequency and serum triglyceride levels of betel-quid chewers were significantly higher than those of non-betel-quid chewers. In this study, we demonstrated that arecoline inhibits adipogenic differentiation, induces adenylyl cyclase-dependent lipolysis, and interferes with insulin-induced glucose uptake. Arecoline-induced fat cell dysfunction may lead to hyperlipidemia and hyperglycemia/insulin-resistance. These findings provide the first in vitro evidence of betel-quid chewing modulation of adipose cell metabolism that could contribute to the explanation of the association of this habit with metabolic syndrome disorders.« less

Awareness and management of chronic disease, insurance status, and health professional shortage areas in the REasons for Geographic And Racial Differences in Stroke (REGARDS): a cross-sectional study

PubMed Central

2012-01-01

Background Limited financial and geographic access to primary care can adversely influence chronic disease outcomes. We examined variation in awareness, treatment, and control of hypertension, diabetes, and hyperlipidemia according to both geographic and financial access to care. Methods We analyzed data on 17,458 participants in the REasons for Geographic And Racial Differences in Stroke (REGARDS) study with either hypertension, hyperlipidemia, or diabetes and living in either complete Health Professional Shortage Area (HPSA) counties or non-HPSA counties in the U.S. All analyses were stratified by insurance status and adjusted for sociodemographics and health behaviors. Results 2,261 residents lived in HPSA counties and 15,197 in non-HPSA counties. Among the uninsured, HPSA residents had higher awareness of both hypertension (adjusted OR 2.30, 95% CI 1.08, 4.89) and hyperlipidemia (adjusted OR 1.50, 95% CI 1.01, 2.22) compared to non-HPSA residents. Also among the uninsured, HPSA residents with hypertension had lower blood pressure control (adjusted OR 0.45, 95% CI 0.29, 0.71) compared with non-HPSA residents. Similar differences in awareness and control according to HPSA residence were absent among the insured. Conclusions Despite similar or higher awareness of some chronic diseases, uninsured HPSA residents may achieve control of hypertension at lower rates compared to uninsured non-HPSA residents. Federal allocations in HPSAs should target improved quality of care as well as increasing the number of available physicians. PMID:22818296

Hepatic LDL receptor (LDLR) and proprotein convertase subtilisin/kexin type 9 (PCSK9) regulate the clearance of plasma LDL-cholesterol (LDL-C): LDLR promotes it, and PCSK9 opposes it. These proteins also express in pancreatic β cells. Using cultured hepatocytes, we previously showed that the plant flavonoid quercetin-3-glucoside (Q3G) inhibits PCSK9 secretion, stimulated LDLR expression, and enhanced LDL-C uptake. Here, we examine whether Q3G supplementation could reverse the hyperlipidemia and hyperinsulinemia of mice fed a high-cholesterol diet, and how it affects hepatic and pancreatic LDLR and PCSK9 expression. For 12 weeks, mice are fed a low- (0%) or high- (1%) cholesterol diet (LCD or HCD), supplemented or not with Q3G at 0.05 or 0.1% (w/w). Tissue LDLR and PCSK9 is analyzed by immunoblotting, plasma PCSK9 and insulin by ELISA, and plasma cholesterol and glucose by colorimetry. In LCD-fed mice, Q3G has no effect. In HCD-fed mice, it attenuates the increase in plasma cholesterol and insulin, accentuates the decrease in plasma PCSK9, and increases hepatic and pancreatic LDLR and PCSK9. In cultured pancreatic β cells, however, it stimulates PCSK9 secretion. In mice, dietary Q3G could counter HCD-induced hyperlipidemia and hyperinsulinemia, in part by oppositely modulating hepatic and pancreatic PCSK9 secretion. © 2018 WILEY-VCH Verlag GmbH & Co.

Tomato is a globally famous food and contains several phytonutrients including lycopene, β-carotene, anthocyanin, and flavonoids. The increased temperature used to produce tomato juice, ketchup, tomato paste and canned tomato enhances the bioactive composition. We aimed to verify the beneficial effects of processed tomato juice from Kagome Ltd. (KOT) on hypolipidemic action in hamsters with hyperlipidemia induced by a 0.2% cholesterol and 10% lard diet (i.e., high-cholesterol diet (HCD)). Male Golden Syrian hamsters were randomly divided into two groups for treatment: normal (n = 8), standard diet (control); and experimental (n = 32), HCD. The 32 hamsters were further divided into four groups (n = 8 per group) to receive vehicle or KOT by oral gavage at 2787, 5573, or 13,934 mg/kg/day for six weeks, designated the HCD-1X, -2X and -5X groups, respectively. The efficacy and safety of KOT supplementation was evaluated by lipid profiles of serum, liver and feces and by clinical biochemistry and histopathology. HCD significantly increased serum levels of total cholesterol (TC), triacylglycerol (TG), high-density lipoprotein cholesterol (HDL-C), and low-density lipoprotein cholesterol (LDL-C), LDL-C/HDL-C ratio, hepatic and fetal TC and TG levels, and degree of fatty liver as compared with controls. KOT supplementation dose-dependently decreased serum TC, TG, LDL-C levels, LDL-C/HDL-C ratio, hepatic TC and TG levels, and fecal TG level. Our study provides experiment-based evidence to support that KOT may be useful in treating or preventing the onset of hyperlipidemia. PMID:26694461

Physicians in Taiwan have a heavy workload and a stressful workplace, both of which may contribute to cardiovascular disease. However, the risk of acute myocardial infarction (AMI) in physicians is not clear. This population-based cohort study used Taiwan's National Health Insurance Research Database. We identified 28,062 physicians as the case group and randomly selected 84,186 nonmedical staff patients as the control group. We used a conditional logistic regression to compare the AMI risk between physicians and controls. Subgroup analyses of physician specialty, age, gender, comorbidities, area, and hospital level were also done. Physicians have a higher prevalence of HTN (23.59% versus 19.06%, P < 0.0001) and hyperlipidemia (21.36% versus 12.93%, P < 0.0001) but a lower risk of AMI than did the controls (adjusted odds ratio (AOR): 0.57; 95% confidence interval (CI): 0.46-0.72) after adjusting for DM, HTN, hyperlipidemia, and area. Between medical specialty, age, and area subgroups, differences in the risk for having an AMI were nonsignificant. Medical center physicians had a lower risk (AOR: 0.42; 95% CI: 0.20-0.85) than did local clinic physicians. Taiwan's physicians had higher prevalences of HTN and hyperlipidemia, but a lower risk of AMI than did the general population. Medical center physicians had a lower risk than did local clinic physicians. Physicians are not necessary healthier than the general public, but physicians, especially in medical centers, have a greater awareness of disease and greater access to medical care, which permits timely treatment and may prevent critical conditions such as AMI induced by delayed treatment.

Employer-sponsored health risk assessments (HRA) may include laboratory tests to provide evidence of disease and disease risks for common medical conditions. We evaluated the ability of HRA-laboratory testing to provide new disease-risk information to participants. We performed a cross-sectional analysis of HRA-laboratory results for participating adult employees and their eligible spouses or their domestic partners, focusing on three common health conditions: hyperlipidemia, diabetes mellitus, and chronic kidney disease. HRA with laboratory results of 52,270 first-time participants were analyzed. Nearly all participants had access to health insurance coverage. Twenty-four percent (12,392) self-reported one or more of these medical conditions: 21.1% (11,017) self-identified as having hyperlipidemia, 4.7% (2,479) self-identified as having diabetes, and 0.7% (352) self-identified as having chronic kidney disease. Overall, 36% (n = 18,540) of participants had laboratory evidence of at least one medical condition newly identified: 30.7% (16,032) had laboratory evidence of hyperlipidemia identified, 1.9% (984) had laboratory evidence of diabetes identified, and 5.5% (2,866) had laboratory evidence of chronic kidney disease identified. Of all participants with evidence of hyperlipidemia 59% (16,030 of 27,047), were newly identified through the HRA. Among those with evidence of diabetes 28% (984 of 3,463) were newly identified. The highest rate of newly identified disease risk was for chronic kidney disease: 89% (2,866 of 3,218) of participants with evidence of this condition had not self-reported it. Men (39%) were more likely than women (33%) to have at least one newly identified condition (p<0.0001). Among men, lower levels of educational achievement were associated with modestly higher rates of newly identified disease risk (p<0.0001); the association with educational achievement among women was unclear. Even among the youngest age range (20 to 29 year olds), nearly 1 in 4 participants (24%) had a newly identified risk for disease. These results support the important role of employer-sponsored laboratory testing as an integral element of HRA for identifying evidence of previously undiagnosed common medical conditions in individuals of all working age ranges, regardless of educational level and gender.

The combined application of statins that inhibit HMG-CoA reductase and fibrates that activate PPAR-α can produce a better lipid-lowering effect than the simple application, but with stronger adverse reactions at the same time. In the treatment of hyperlipidemia, the combined administration of TCMs and HMG-CoA reductase inhibitor in treating hyperlipidemia shows stable efficacy and less adverse reactions, and provides a new option for the combined application of drugs. In this article, the pharmacophore technology was used to search chemical components of TCMs, trace their source herbs, and determine the potential common TCMs that could activate PPAR-α. Because there is no hyperlipidemia-related medication reference in modern TCM classics, to ensure the high safety and efficacy of all selected TCMs, we selected TCMs that are proved to be combined with statins in the World Traditional/Natural Medicine Patent Database, analyzed corresponding drugs in pharmacophore results based on that, and finally obtained common TCMs that can be applied in PPAR-α and combined with statins. Specifically, the pharmacophore model was based on eight receptor-ligand complexes of PPAR-α. The Receptor-Ligand Pharmacophore Generation module in the DS program was used to build the model, optimize with the Screen Library module, and get the best sub-pharmacophore, which consisted of two hydrogen bond acceptor, three hydrophobic groups and 19 excluded volumes, with the identification effectiveness index value N of 2. 82 and the comprehensive evaluation index CAI value of 1. 84. The model was used to screen the TCMD database, hit 5,235 kinds of chemical components and 1 193 natural animals and plants, and finally determine 62 TCMs. Through patent retrieval, we found 38 TCMs; After comparing with the virtual screening results, we finally got seven TCMs.

Little is known about the health-related quality of life (HRQoL) and work-related stress and its risk factors among white-collar businessmen and management workers that migrate to high-income developing countries. A structural questionnaire survey was administered to 156 white-collar Taiwanese management personnel of representative companies of their industries in Taiwan, who were assigned long-term job positions in China. Questionnaire content included demographics and medical history, self-reported physical and mental conditions, personal lifestyle and behavior, Beck Depression Inventory, and information on HRQoL. White-collar migrant workers reported a high prevalence of alcohol consumption (72.4%) and perceived work-related stress (62.2%), and a lower prevalence of regular exercise (12.2%). Workers with higher levels of perceived work-related stress reported more alcohol consumption, a history of hyperlipidemia, and a higher prevalence of self-reported neck pain, poor sleep, and mild/moderate/severe depression. In our primary multivariate risk model to determine lifestyle and work-related stress variables and HRQoL, perceived work-related stress and a feeling of depression negatively impacted both the Physical Component Summary (PCS) and Mental Component Summary (MCS) scores of the SF-36 health survey. Hyperlipidemia and self-reported neck pain were associated with significantly lower PCS scores, whereas cardiovascular disease, gastric ulcer, and poor sleep were associated with statistically lower MCS scores. White-collar migrant workers are generally younger with high socioeconomic status. Perceived work-related stress and a feeling of depression indirectly affect HRQoL. Hyperlipidemia, self-reported neck pain, cardiovascular disease, gastric ulcer, and poor sleep also had a significant negative impact on HRQoL.

Although ethnic or cultural differences affect prevalence of cardiovascular risk factors, limited information is available about the age- and gender-stratified prevalence of the risk factors in Asian stroke population. We assessed gender- and age-stratified prevalences of major risk factors in Korean stroke patients, and assumed that the gender differences are attenuated by adjustment with lifestyle factors. Using the nationwide hospital-based stroke registry, we identified 9417 ischemic stroke patients admitted between April 2008 and January 2011. Prevalence of hypertension, diabetes, hyperlipidemia, atrial fibrillation, prior stroke, and coronary heart disease was assessed in both genders by age groups. We analyzed gender differences of the prevalence among the age groups by calculating prevalence ratio, and further explored the influence of lifestyle factors on the gender difference in multivariable analyses. Hypertension and hyperlipidemia were more common in men until middle age, but after that more common in women, whereas diabetes was more common in women after 65 years of age. Atrial fibrillation increased steadily with age in both genders but was more common in women through all age groups. Prior stroke and coronary heart disease showed inconsistent gender differences. Gender differences in hypertension and diabetes among the age groups were attenuated by adjustment with accompanying risk factors including lifestyle factors. Korean women with stroke had more hypertension and hyperlipidemia after middle age, more diabetes after 65 years, and more atrial fibrillation throughout all ages. Strategies to control risk factors in women at risk for stroke are eagerly needed. © 2013 The Authors. International Journal of Stroke © 2013 World Stroke Organization.

Racial/ethnic minority patients are more likely to report experiences with discrimination in the healthcare setting, potentially leading to reduced access to appropriate care; however, few studies evaluate reports of discrimination with objectively measured quality of care indicators. To evaluate whether patient-reported racial/ethnic discrimination by healthcare providers was associated with evidence of poorer quality care measured by medication intensification. Baseline data from the Diabetes Study of Northern California (DISTANCE), a random, race-stratified sample from the Kaiser Permanente Diabetes Registry from 2005-2006, including both survey and medical record data. Self-reported healthcare provider discrimination (from survey data) and medication intensification (from electronic prescription records) for poorly controlled diabetes patients (A1c ≥9.0%; systolic BP ≥140 mmHg or diastolic BP ≥90 mmHg; low-density lipoprotein (LDL) ≥130 mg/dl). Of 10,409 eligible patients, 21% had hyperglycemia, 14% had hyperlipidemia, and 32% had hypertension. Of those with hyperglycemia, 59% had their medications intensified, along with 40% with hyperlipidemia, 33% with hypertension, and 47% in poor control of any risk factor. In adjusted log-binomial GEE models, discrimination was not associated with medication intensification [RR = 0.96 (95% CI: 0.74, 1.24) for hyperglycemia, RR = 1.23 (95% CI: 0.93, 1.63) for hyperlipidemia, RR = 1.06 (95% CI: 0.69, 1.61) for hypertension, and RR = 1.08 (95% CI: 0.88, 1.33) for the composite cohort]. We found no evidence that patient-reported healthcare discrimination was associated with less medication intensification. While not associated with this technical aspect of care, discrimination could still be associated with other aspects of care (e.g., patient-centeredness, communication).

The influence of various statins on low-density-lipoprotein (LDL)-particle phenotype has been reportedly trivial or moderate. We assessed the effect of rosuvastatin (the newest statin available) on the LDL subfraction profile in patients with primary hyperlipidemia. One hundred and twenty patients with primary hyperlipidemia without evidence of cardiovascular disease were randomized to therapeutic lifestyle modification ('control' group, N=60) or therapeutic lifestyle modification plus rosuvastatin 20 mg/day (N=60). Laboratory evaluation was performed at baseline and 12 weeks post-treatment. LDL subfraction analysis was carried out electrophoretically using of high-resolution 3% polyacrylamide gel tubes and the Lipoprint LDL System. Rosuvastatin induced a redistribution of LDL-cholesterol from small-dense LDL particles to large-buoyant ones and increased the mean LDL particle size. This beneficial effect was observed only in patients with baseline triglyceride levels >or=150 mg/dl (mean LDL particle size 255+/-7 A vs 260+/-5 A, P<0.01), whereas the LDL subfraction profile was not altered in those with triglyceride levels <150 mg/dl. Stepwise multivariate linear regression analysis revealed that baseline triglyceride levels (R(2)=0.29, P=0.001) followed by baseline insulin resistance as assessed by the HOmeostasis Model Assessment (HOMA) (R(2)=0.25, P=0.001) were independently associated with the rosuvastatin-induced increase in the mean LDL particle size. In conclusion, rosuvastatin at 20 mg/day favorably modified the relative distribution of LDL-cholesterol distribution on LDL subfractions as well as on the mean LDL particle size in patients treated for primary dyslipidemia. Baseline triglyceride levels as well as baseline HOMA-index were found to be the major predictors of this beneficial action of rosuvastatin.

Background Tinnitus is a common condition in adults; however, the pathophysiology of tinnitus remains unclear, and no large population-based study has assessed the associated risk factors. The aim of this study was to analyze the prevalence and associated risk factors of tinnitus. Methods We conducted a cross-sectional study using data from the Korea National Health and Nutrition Examination Survey, with 19,290 participants ranging in age from 20 to 98 years old, between 2009 and 2012. We investigated the prevalence of tinnitus using a questionnaire and analyzed various possible factors associated with tinnitus using simple and multiple logistic regression analysis with complex sampling. Results The prevalence of tinnitus was 20.7%, and the rates of tinnitus associated with no discomfort, moderate annoyance, and severe annoyance were 69.2%, 27.9%, and 3.0%, respectively. The prevalence of tinnitus and the rates of annoying tinnitus increased with age. The adjusted odds ratio (AOR) of tinnitus was higher for females, those with a smoking history, those reporting less sleep (≤ 6 h), those with more stress, those in smaller households, those with a history of hyperlipidemia osteoarthritis, rheumatoid arthritis, asthma, depression, thyroid disease, an abnormal tympanic membrane, unilateral hearing loss, bilateral hearing loss, noise exposure from earphones, noise exposure at the workplace, noise exposure outside the workplace, and brief noise exposure. Additionally, unemployed individuals and soldiers had higher AORs for tinnitus. The AOR of annoying tinnitus increased with age, stress, history of hyperlipidemia, unilateral hearing loss, and bilateral hearing loss. Conclusions Tinnitus is very common in the general population and is associated with gender, smoking, stress, sleep, hearing loss, hyperlipidemia, osteoarthritis, rheumatoid arthritis, asthma, depression, and thyroid disease history.

Influence of diadenosine tetraphosphate (Ap4A) on lipid metabolism.

PubMed

Rüsing, D; Verspohl, E J

2004-01-01

Diadenosine polyphosphates (Ap(x)A) are physiologically released and may be partly involved in the pathogenesis of diabetes mellitus. Ap(4)A (diadenosine tetraphosphate) leads to an increase in blood glucose while it decreases insulin levels in plasma. A possible link between Ap(x)A and diabetes mellitus-associated diseases such as insulin resistance and hyperlipidemia (plasma free fatty acids, cholesterol and its biosynthesis, triacylglycerols) has not been investigated yet. Parameters such as free fatty acid and cholesterol content in blood were determined enzymically. The biosynthesis of cholesterol and triacylglycerols was determined in HepG2 cells using the radioactive precursor [(14)C]-acetate and by using gas chromatography. Plasma free fatty acids were significantly decreased 5 and 10 min after an Ap(4)A bolus (0.75 mg kg(-1) b.w.) given to rats. Plasma cholesterol was reduced 5 and 60 min after Ap(4)A administration. LPDS (lipoprotein-deficient serum)-stimulated cholesterol biosynthesis in HepG2 cells was significantly reduced after 1 h incubation with Ap(4)A. Triacylglycerol (TAG) biosynthesis in HepG2 cells was not significantly influenced by Ap(4)A; there was just a tendency for a concentration-dependent decrease in TAG levels. In conclusion Ap(4)A as a diabetogenetic compound is not likely to be responsible for the development of insulin resistance or of hyperlipidemia. Parameters such as free fatty acids, cholesterol and triacylglycerols are not elevated by Ap(4)A, but are even decreased. Ap(4)A seems to be involved in the development of diabetes mellitus by increasing blood glucose and decreasing plasma insulin as shown earlier, but not in diabetes mellitus-associated diseases such as insulin resistance or hyperlipidemia.

This cohort study used data from all patients, aged≥30, registered in 140 primary care practices (n=524,952) in London to estimate the risk of developing diabetes, hypertension, hyperlipidemia, tobacco consumption, obesity, and physical inactivity, between 2005 and 2015, for patients with a previous diagnosis of schizophrenia, depression, anxiety, bipolar or personality disorder. The role of antidepressants, antipsychotics and social deprivation in these associations was also investigated. The age at detection of cardiovascular risk factor was compared between patients with and without psychiatric disorders. Variables, for exposures and outcomes, defined from general practitioners records, were analysed using multivariate regression. Patients with psychiatric disorders had an increased risk for cardiovascular risk factors, especially diabetes, with hazard ratios: 2.42 (2.20-2.67) to 1.31 (1.25-1.37), hyperlipidemia, with hazard ratios: 1.78 (1.60-1.97) to 1.25 (1.23-1.28), and obesity. Antidepressants, antipsychotics and social deprivation did not change these associations, except for smoking and physical inactivity. Antidepressants were associated with higher risk of diabetes, hypertension and hyperlipidemia. Antipsychotics were associated with a higher risk of diabetes. Antidepressants and antipsychotics were associated with lower risk of other risk factors. Patients with psychiatric conditions have later detection of cardiovascular risk factors. The interpretation of these results should acknowledge the lower rates of detection of risk factors in mentally ill patients. Cardiovascular risk factors require special clinical attention among patients with psychiatric disorders. Further research could study the effect of antidepressants and antipsychotics on cardiovascular risk factors. Copyright © 2016 Elsevier Masson SAS. All rights reserved.

Introduction Despite definite recognition of major atherosclerotic risk factors, the relationship between the pattern of coronary artery disease and these risk factors is unknown. Aim The aim of this study was to identify the relationship between some of the major atherosclerotic risk factors and the number and pattern of coronary artery disease in patients with coronary artery disease who presented to Farshchian Heart University Hospital, Hamadan, Iran. Materials and Methods In this descriptive cross-sectional study, we investigated some of the major atherosclerotic risk factors and their relationships with the type of coronary artery disease in terms of number and location of disease. A total of 1100 patients were enrolled with coronary artery disease confirmed by selective coronary angiography from 2010-2014. A p-value<0.05 was considered statistically significant. Results A total of 1100 patients enrolled in this study. The patient population consisted of 743 (67.5%) males and 357 (32.5%) females. A meaningful relationship existed between ageing, diabetes mellitus, hypertension and 3-Vessel Disease (3VD, p<0.001) as well as between hyperlipidemia and Single Vessel Disease (SVD, p<0.001). Patients diagnosed with diabetes mellitus, hypertension, and hyperlipidemia showed greater potential to develop coronary artery disease at the proximal section of the coronary arteries. Conclusion Based on the relationship between some of the major risk factors and the pattern of coronary artery disease in the current study, prospective studies should investigate other risk factors. We recommend that a plan should be developed to reduce adjustable risk factors such as diabetes mellitus, hypertension and hyperlipidemia in order to decrease coronary artery disease. PMID:28969179

A large proportion of human T cells are autoreactive to group 1 CD1 proteins, which include CD1a, CD1b, and CD1c. However, the physiological role of the CD1 proteins remains poorly defined. Here, we have generated a double-transgenic mouse model that expresses human CD1b and CD1c molecules (hCD1Tg) as well as a CD1b-autoreactive TCR (HJ1Tg) in the ApoE-deficient background (hCD1Tg HJ1Tg Apoe–/– mice) to determine the role of CD1-autoreactive T cells in hyperlipidemia-associated inflammatory diseases. We found that hCD1Tg HJ1Tg Apoe–/– mice spontaneously developed psoriasiform skin inflammation characterized by T cell and neutrophil infiltration and a Th17-biased cytokine response. Anti–IL-17A treatment ameliorated skin inflammation in vivo. Additionally, phospholipids and cholesterol preferentially accumulated in diseased skin and these autoantigens directly activated CD1b-autoreactive HJ1 T cells. Furthermore, hyperlipidemic serum enhanced IL-6 secretion by CD1b+ DCs and increased IL-17A production by HJ1 T cells. In psoriatic patients, the frequency of CD1b-autoreactive T cells was increased compared with that in healthy controls. Thus, this study has demonstrated the pathogenic role of CD1b-autoreactive T cells under hyperlipidemic conditions in a mouse model of spontaneous skin inflammation. As a large proportion of psoriatic patients are dyslipidemic, this finding is of clinical significance and indicates that self-lipid–reactive T cells might serve as a possible link between hyperlipidemia and psoriasis.

To evaluate the long-term remission rates of type 2 diabetes mellitus and associated comorbidities after gastric bypass surgery in a complete cohort, in a real-life clinic setting. A retrospective study of all consecutive patients with type 2 diabetes mellitus who underwent gastric bypass at a Veterans Affairs Medical Center from 2003 to 2010. The main outcome was remission of type 2 diabetes mellitus defined as HbA1c <6.5% (49 mmol/mol) without diabetic medication usage. Secondary outcomes were remission of hypertension and hyperlipidemia, weight loss, and long-term complications four years post-gastric bypass. Eighty-four patients with type 2 diabetes mellitus underwent gastric bypass. Four-year follow-up data were available for 92% (77/84) of patients. The patients (73% male; mean age 54 years) had a mean body mass index of 49 kg/m 2  ± 8.3. Hypertension and hyperlipidemia prevalence were 92% and 85%, respectively. The mean total body weight decrease over four years was 35 kg ± 21. Remission of type 2 diabetes mellitus occurred in 15% at 6 months and 49% four years after surgery. Diabetes remission was more likely (OR 3.2; 95% confidence interval 1.2-9.7) in patients not using insulin at baseline. Remission rates were 12% (9/74) for hypertension and 16% (11/68) for hyperlipidemia. Long-term surgical complications included reoperation (11%), incisional hernia (10%) and anastomotic ulcer (10%). Forty-four percent of patients had one or more nutritional complications. The metabolic effects of gastric bypass are significant and durable for at least four years, even in a predominantly male cohort and real-life clinical setting. Published by Elsevier B.V.

Modified Lingguizhugan Decoction (MLD) came from famous Chinese medicine Linggui Zhugan Decoction. The MLD is used for the treatment of metabolic syndrome in the clinical setting. Our study focuses on the comprehensive treatment of MLD incorporated with dietary restriction and exercise in a rat model of the metabolic syndrome (MS). Rats were divided into five groups: control group (Cont), high-fat diet group (HFD), high-fat diet incorporated with dietary restriction group (HFD-DR), exercise incorporated with dietary restriction group (HFD-DR-Ex) and MLD incorporated with dietary restriction and exercise group (HFD-DR-Ex-MLD). Treatments were conducted for 1 week after feeding high-fat diet for 12 weeks. The effects of treatments on high fat diet-induced obesity, hyperglycemia, hyperlipidemia, hypertension, hepatic injury and insulin resistance in rats of MS were examined. In addition, the tumor necrosis factor-α (TNF-α), leptin and protein kinase B (PKB) in rats serum and liver were also examined by enzyme-linked immunosorbent assay (ELISA). After a week's intervention by dietary restriction, dietary restriction incorporated with exercise or MLD, compared with HFD rats, the relative weight of liver and fat, levels of triglyceride, total cholesterol, low-density lipoprotein, free fatty acid, aspartate aminotransferase, glutamic-pyruvic transaminase and alkaline phosphatase, insulin, were significantly decreased (p < 0.05 or 0.01). This treatment also inhibited abnormal increases of TNF-α, leptin and PKB in serum and liver. MLD incorporated with dietary restriction and exercise treatment exhibit effects in alleviating high-fat diet-induced obesity, hyperglycemia, hyperlipidemia, hypertension, hepatic injury and insulin resistance, which are possibly due to the down-regulation of TNF-α, leptin and PKB.

The objective of this study is to develop an experimental model of hyperlipidemia and insulin resistance (IR), markers of coronary heart disease (CHD) using high fat and high sugar (HFHS) diet and to evaluate the efficacy of the model using atorvastatin, a known antihyperlipidemic drug, pioglitazone, a known insulin sensitizer, and Tinospora cordifolia (Tc), an antidiabetic plant. Following Institutional Animal Ethics Committee permission, the study was conducted in male Wistar rats (200-270 g). The model was developed using a high fat (vanaspati ghee: coconut oil, 3:1) oral diet along with 25% fructose (high sugar) added in drinking water over a period of 6 weeks. Atorvastatin (2.1 mg/kg/day), pioglitazone (2.7 mg/kg/day) and Tc (200 mg/kg/day) were administered 3 weeks after initiation of HFHS diet and continued for another 3 weeks. Parameters assessed were weight, lipid profile, fasting blood glucose, insulin, and gastric emptying. Serum malondialdehyde (MDA) and catalase were assessed as markers of oxidative stress. Administration of HFHS diet demonstrated a significant increase in blood glucose, insulin, total and low density lipoprotein cholesterol and triglycerides with a decrease in high density lipoprotein cholesterol. Treatment with test drugs decreased blood sugar, insulin, lipid parameters, increased gastric emptying rate, decreased MDA levels, and catalase activity when compared to HFHS diet group, confirming the efficacy of the model. Atherogenic index of all the test drugs (0.48, 0.57, and 0.53) was significantly lower as compared to HFHS diet group (1.107). This study confirms the development of a diet based cost-effective and time efficient experimental model, which can be used to study two important markers of cardiovascular disease that is, hyperlipidemia and IR and to explore the efficacy of new molecules in CHD.

Salacia oblonga root improves postprandial hyperlipidemia and hepatic steatosis in Zucker diabetic fatty rats: Activation of PPAR-{alpha}

Hsun-Wei Huang, Tom; Peng Gang; Qian Li, George

Salacia oblonga (SO) root is an Ayurvedic medicine with anti-diabetic and anti-obese properties. Peroxisome proliferator-activated receptor (PPAR)-{alpha}, a nuclear receptor, plays an important role in maintaining the homeostasis of lipid metabolism. Here, we demonstrate that chronic oral administration of the water extract from the root of SO to Zucker diabetic fatty (ZDF) rats, a genetic model of type 2 diabetes and obesity, lowered plasma triglyceride and total cholesterol (TC) levels, increased plasma high-density lipoprotein levels and reduced the liver contents of triglyceride, non-esterified fatty acids (NEFA) and the ratio of fatty droplets to total tissue. By contrast, the extract hadmore » no effect on plasma triglyceride and TC levels in fasted ZDF rats. After olive oil administration to ZDF the extract also inhibited the increase in plasma triglyceride levels. These results suggest that SO extract improves postprandial hyperlipidemia and hepatic steatosis in ZDF rats. Additionally, SO treatment enhanced hepatic expression of PPAR-{alpha} mRNA and protein, and carnitine palmitoyltransferase-1 and acyl-CoA oxidase mRNAs in ZDF rats. In vitro, SO extract and its main component mangiferin activated PPAR-{alpha} luciferase activity in human embryonic kidney 293 cells and lipoprotein lipase mRNA expression and enzyme activity in THP-1 differentiated macrophages; these effects were completely suppressed by a selective PPAR-{alpha} antagonist MK-886. The findings from both in vivo and in vitro suggest that SO extract functions as a PPAR-{alpha} activator, providing a potential mechanism for improvement of postprandial hyperlipidemia and hepatic steatosis in diabetes and obesity.« less

Aim: We investigated the safety and efficacy of a long-term combination therapy with fenofibrate and ezetimibe in Japanese patients with combined hyperlipidemia, in comparison with fenofibrate or ezetimibe alone. Methods: The study was a three-arm parallel-group, open-label randomized trial. Eligible patients were assigned to a combination therapy with fenofibrate (200 mg/day in capsule form or 160 mg/day in tablet form) and ezetimibe (10 mg/day), the fenofibrate monotherapy, or the ezetimibe monotherapy, which lasted for 52 weeks. The changes in serum low-density lipoprotein (LDL) cholesterol and triglycerides were the primary outcomes. Results: A total of 236 patients were assigned to one of the three treatments, and the number of patients included in the final analysis was 107 in the combination therapy, 52 in the fenofibrate monotherapy, and 51 in the ezetimibe monotherapy. Mean ± SD changes in LDL cholesterol were −24.2% ± 14.7% with combination therapy, −16.0% ± 16.0% with fenofibrate alone, and −17.4% ± 10.1% with ezetimibe alone. The combination therapy resulted in a significantly greater reduction in LDL cholesterol as compared with each monotherapy (p < 0.01 for each). The corresponding values for triglycerides were −40.0% ± 29.5%, −40.1% ± 28.7%, and −3.4% ± 32.6%, respectively. Fenofibrate use was associated with some changes in laboratory measurements, but there was no differential adverse effect between the combination therapy and fenofibrate monotherapy. Conclusion: The combination therapy with fenofibrate and ezetimibe substantially reduces concentrations of LDL cholesterol and triglycerides and is safe in a long-term treatment in Japanese patients with combined hyperlipidemia.

2013-01-01

In this study, ethanolic extracts from Hericium erinaceum cultivated with Artemisia capillaris (HEAC) were assessed for their ability to lower the cholesterol levels of male Sprague-Dawley rats fed a high-fat diet. Rats were randomly subdivided into seven test groups. Each group contained eight rats fed a high-fat diet during a growth period lasting 4 wk. Supplementation with the extracts was performed once a day for 2 wk after the high-fat diet. The control group (rats fed a high-fat diet) showed a high efficiency ratio (feed efficiency ratio) value compared to the normal group. Biochemical parameters, including total cholesterol (TC), low-density lipoprotein-cholesterol (LDL-c), and triglyceride (TG) levels dramatically increased in the control group compared to the normal group. High-density lipoprotein-cholesterol (HDL-c) content in the control group was also significantly lower relative to the normal group. Two positive control groups, treated with simvastatin and atorvastatin, had lowered TC, LDL-c, and TG levels, and increased HDL-c content compared to the control group. Treatment with the tested extracts, including HEAC, ethanolic extracts from Hericium erinaceum, and ethanolic extracts from Artemisia capillaris reduced TC, LDL-c, and TG levels and elevated HDL-c content in the hyperlipidemia rats. The atherogenic index and cardiac risk factor values for the HEAC-treated group were 0.95 and 1.95, respectively. Simvastatin- and atorvastatin-treated groups showed atherogenic index values of 1.56 and 1.69, respectively, and cardiac risk factor values of 2.56 and 2.69, respectively. These results show HEAC possesses an ability to cure hyperlipidemia in rats and may serve as an effective natural medicine for treating hyperlipidemia in humans. PMID:23874132

Lipoprotein Profile Modifications during Gestation: A Current Approach to Cardiovascular risk surrogate markers and Maternal-fetal Unit Complications.

PubMed

Santos, Ana Paula Caires Dos; Couto, Ricardo David

2018-05-16

Several changes occur in lipid metabolism during gestation due to hormonal and metabolic changes, which are essential to satisfy the nutritional demands of the maternal-fetal unit development. The gestation shows two distinct periods that begin with fat accumulation, mainly in maternal adipose tissue, and the late phase, characterized by accelerated catabolism, with the increase of fatty acids in the circulation that causes hyperlipidemia, especially the one characterized as hypertriglyceridemia. Maternal hyperlipidemia may be associated with the development of maternal-fetal complications (preterm birth, preeclampsia, vascular complications) and the development of long-term cardiovascular disease. The cardiovascular risk may not only be related to lipoproteins cholesterol content, but also to the number and functionality of circulating lipoprotein particles. This review reports the major changes that occur in lipoprotein metabolism during pregnancy and that are associated with the development of dyslipidemias, lipoprotein atherogenic phenotype, and maternal-fetal unit complications.

Baghshomali, Sanam; Bushnell, Cheryl

2014-09-01

Stroke is a major cause of death and disability in adults worldwide. Prevention focused on modifiable risk factors, such as hypertension and hyperlipidemia, has shown them to be of significant importance in decreasing the risk of stroke. Multiple studies have brought to light the differences between men and women with regards to stroke and these risk factors. Women have a higher prevalence of stroke, mortality and disability and it has been shown that preventive and treatment options are not as comprehensive for women. Hence, it is of great necessity to evaluate and summarize the differences in gender and stroke risk factors in order to target disparities and optimize prevention, especially because women have a higher lifetime risk of stroke. The purpose of this review is to summarize sex differences in the prevalence of hypertension and hyperlipidemia. In addition, we will review the sex differences in stroke prevention effectiveness and adherence to blood pressure and cholesterol medications, and suggest future directions for research to reduce the burden of stroke in women.

This pilot project aimed to improve depression symptoms and quality-of-life measures for individuals in a worksite disease management program. Two hundred forty-three individuals were invited to participate, out of which 69 enrolled. The participants had a history of diabetes, hypertension, or hyperlipidemia, and demonstrated depression using the Patient Health Questionnaire-9 (PHQ-9). The project consisted of counseling sessions provided every 2 to 4 weeks by a family nurse practitioner. PHQ-9 scores and those of an instrument that measures quality of life, the Veteran's Rand-12 (VR-12), were compared pre-intervention and post-intervention to evaluate the effectiveness of the project. PHQ-9 and VR-12 Mental Health Component (MHC) scores improved significantly after 3 months of nurse practitioner-led individual counseling sessions. This project demonstrated that depression screening and therapeutic management, facilitated by a nurse practitioner, can improve depression and perceived quality of life in individuals with hypertension, hyperlipidemia, or type 2 diabetes. © 2015 The Author(s).

Effect of Instant Cooked Giant Embryonic Rice on Body Fat Weight and Plasma Lipid Profile in High Fat-Fed Mice

2014-01-01

The comparative effects of instant cooked rice made from giant embryo mutant or ordinary normal rice on body weight and lipid profile in high fat-fed mice were investigated. The animals were given experimental diets for seven weeks: normal control (NC), high fat (HF), and HF supplemented with instant normal white (HF-NW), normal brown (HF-NB), giant embryonic white (HF-GW), or giant embryonic brown (HF-GB) rice. The HF group showed markedly higher body weight, body fat, plasma and hepatic triglyceride and cholesterol concentrations, and atherogenic index relative to NC group. However, instant rice supplementation counteracted this high fat-induced hyperlipidemia through regulation of lipogenesis and adipokine production. The GB rice exhibited greater hypolipidemic and body fat-lowering effects than the GW or NB rice. These findings illustrate that the giant embryo mutant may be useful as functional biomaterial for the development of instant rice with strong preventive action against high fat diet-induced hyperlipidemia and obesity.

Familial combined hyperlidemia (FCH) is a common metabolic disorder characterized by: (a) increase in cholesterolemia and/or triglyceridemia in at least two members of the same family, (b) intra-individual and intrafamilial variability of the lipid phenotype, and (c) increased risk of premature coronary heart disease (CHD). FCH is very frequent and is one of the most common genetic hyperlipidemias in the general population (prevalence estimated: 0.5%–2.0%), being the most frequent in patients affected by CHD (10%) and among acute myocardial infarction survivors aged less than 60 (11.3%). This percentage increases to 40% when all the myocardial infarction survivors are considered without age limits. However, because of the peculiar variability of laboratory parameters, and because of the frequent overlapping with the features of metabolic syndrome, this serious disease is often not recognized and treated. The aim of this review is to define the main characteristics of the disease in order to simplify its detection and early treatment by all physicians by mean of practical guidelines. PMID:18200807

The case of a 7-year-old boy with virus-associated hemophagocytic syndrome (VAHS) and serologically proven parvovirus B-19 infection is described. The patient with VAHS presented with fever, hepatosplenomegaly, pancytopenia, and hyperlipidemia type IV. After induction therapy with VP-16 and prednisone, partial remission was achieved. Despite maintenance therapy, reinductions, and the addition of cyclosporine A for 3 months, several relapses occurred. The therapy was stopped because of life-threatening complications (Klebsiella sepsis, neutropenic enterocolitis, and stercoral peritonitis). The complications were treated successfully. The patient status was stabilized after splenectomy. However, hepatomegaly progressed slowly and the hyperlipidemia endured. Ten months after the diagnosis leukocytosis with absolute T lymphocytosis appeared. Reactivation of VAHS was suspected and intravenous immunoglobin and then antilymphocyte immunoglobulin ALG therapy were started. The resultant decrease in leukocytosis was prompt, but lymphopenia did not occur. Virostatic treatment with foscarnet was introduced based on human herpesvirus-6 seroconversion. Twenty-six months after the diagnosis, the patient is well, without any sign of VAHS or lymphoproliferation.

The aim of the present study was to evaluate the correlation between calcified carotid atheromas (CCA) detected on digital panoramic radiographs and underlying systemic diseases. Panoramic radiographs and underlying systemic diseases of retained mandibular denture implants in 265 patients (56 males, 209 females) aged over 50 years were retrospectively evaluated at the Dental Unit of Prasat Neurological Institute, Bangkok, Thailand. The mean age of the patients was 71 ± 7.1 years. The prevalence of CCA was 38.49%. The major underlying systemic diseases were hypertension, hyperlipidemia, diabetes mellitus, and cardiovascular diseases (CVD), respectively. No relationship was found among these four systemic diseases in detecting CCA on panoramic radiographs. Similar findings were also observed in patients with only one systemic disease versus in combination with other diseases. The presence of CCA on dental panoramic radiographs was not found to be related to the presence of underlying systemic diseases, including hypertension, hyperlipidemia, diabetes mellitus, and CVD. © 2014 Wiley Publishing Asia Pty Ltd.

Hydrosol beverages in Persian nutrition culture and ethnomedicine are the side products of essential oil industry that are used as delicious drinks or safe remedies. To investigate indications and chemical composition of hydrosol beverages for hyperlipidemia and cardiovascular conditions, Fars province was selected as the field of study. Ethnomedical data were gathered by questionnaires. The constituents of hydrosols were extracted with liquid/liquid extraction and analyzed by gas chromatography–mass spectrometry. Statistical analysis were used to cluster their constituents and find the relevance of their composition. A literature survey was also performed on plants used to prepare them. Thymol was the major or second major component of these beverages, except for wormwood and olive leaf hydrosols.

Anthocyanins are the main compounds in Nitraria tangutorun Bobr. The enrichment and purification of anthocyanins on macroporous resins were investigated. Regarding anthocyanin purification, static adsorption and desorption were studied. The optimal experimental conditions were the following: resin type: X-5; static adsorption time: 6h; desorption solution: ethanol-water-HCl (80:19:1, V/V/V; pH 1); desorption time: 40min. Furthermore, the in vitro and in vivo biological activities of the anthocyanins were evaluated. The anthocyanins showed ideal scavenging effects on free radicals in vitro, especially on 1,1-diphenyl-2-picrylhydrazyl (DPPH) and hydroxyl free radical (OH). In the animal experiment, blood lipid metabolism of hyperlipidemia rats was regulated by anthocyanin contents. The superoxide dismutase (SOD) activity and the total antioxidant capacity (TAC) of hyperlipidemia rats were also improved by anthocyanins. These results showed that anthocyanins from N. tangutorun Bobr. fruits had potential biological activities in vivo as well as in vitro. Copyright © 2015. Published by Elsevier Ltd.

Prior studies of the Medicare Part D coverage gap are limited in generalizability and scope. To determine the effect of the coverage gap on drugs used for asymptomatic (antihypertensive and lipid-lowering drugs) and symptomatic (pain relievers, acid suppressants, and antidepressants) conditions in elderly patients with hypertension and hyperlipidemia. Quasi-experimental study using pre-post design and contemporaneous control group. Medicare claims files from 2005 and 2006 for 5% random sample of Medicare beneficiaries. Part D plan enrollees with hypertension or hyperlipidemia aged 65 years or older who had no coverage, generic-only coverage, or both brand-name and generic coverage during the gap in 2006. Patients who were fully eligible for the low-income subsidy served as the control group. Monthly 30-day supply prescriptions available, medication adherence, and continuous medication gaps of 30 days or more for antihypertensive or lipid-lowering drugs; monthly 30-day supply prescriptions available for pain relievers, acid suppressants, or antidepressants before and after coverage gap entry. Patients with no gap coverage had a decrease in monthly antihypertensive and lipid-lowering drug prescriptions during the coverage gap. Nonadherence also increased in this group (antihypertensives: odds ratio [OR], 1.60 [95% CI, 1.50 to 1.71]; lipid-lowering drugs: OR, 1.59 [CI, 1.50 to 1.68]). The proportion of patients with no gap coverage who had continuous medication gaps in lipid-lowering medication use and antihypertensive use increased by an absolute 7.3% (OR, 1.38 [CI, 1.29 to 1.46]) and 3.2% (OR, 1.35 [CI, 1.25 to 1.45]), respectively, because of the coverage gap. Decreases in use were smaller for pain relievers and antidepressants and larger for acid suppressants in patients with no gap coverage. Patients with generic-only coverage had decreased use of cardiovascular medications but no change in use of drugs for symptomatic conditions. No measures changed in the brand-name and generic coverage groups. Results of sensitivity analyses were consistent with the main findings. Because this study was nonrandomized, unobserved differences may still exist between study groups. The Part D coverage gap was associated with decreased use of medications for hypertension and hyperlipidemia in patients with no gap coverage and generic-only gap coverage. The proposed phasing out of the gap by 2020 will benefit such patients; however, use of low-value medications may also increase. Penn-Pfizer Alliance and American Heart Association.

Berberine, extracted from Coptis Root and Phellodendron Chinese, has been frequently used for the adjuvant treatment of type 2 diabetes mellitus, hyperlipidemia, and hypertension in China. Safety and efficacy studies in terms of evidence-based medical practice have become more prevalent in application to Chinese Herbal Medicine. It is necessary to assess the efficacy and safety of berberine in the treatment of type 2 diabetes mellitus, hyperlipidemia and hypertension by conducting a systematic review and meta-analysis of available clinical data. We searched the English databases PubMed, ScienceDirect, Cochrane library, EMbase, etc., and Chinese databases including China biomedical literature database (CBM), Chinese Technology Journal Full-text Database, Chinese journal full text database (CNKI), and Wanfang digital periodical full text database. Relevant studies were selected based on the inclusion and exclusion criteria. Meta-analysis was performed with RevMan5.0 software after data extraction and the quality of studies assessment. Twenty-seven randomized controlled clinical trials were included with 2569 patients. There are seven subgroups in our meta-analysis: berberine versus placebo or berberine with intensive lifestyle intervention versus intensive lifestyle intervention alone; berberine combined with oral hypoglycemic versus hypoglycemic alone; berberine versus oral hypoglycemic; berberine combined with oral lipid lowering drugs versus lipid lowering drugs alone; berberine versus oral lipid lowering drugs; berberine combined with oral hypotensor versus hypotensive medications; berberine versus oral hypotensive medications. In the treatment of type 2 diabetes mellitus, we found that berberine with lifestyle intervention tended to lower the level of FPG, PPG and HbA1c than lifestyle intervention alone or placebo; the same as berberine combined with oral hypoglycaemics to the same hypoglycaemics; but there was no statistical significance between berberine and oral hypoglycaemics. As for the treatment of hyperlipidemia, berberine with lifestyle intervention was better than lifestyle intervention, berberine with oral lipid lowering drugs was better than lipid lowering drugs alone in reducing the level of TC and LDL-C, and raising the level of HDL-C. In the comparative study between berberine and oral lipid lowering drugs, there was no statistical significance in reducing the level of TC and LDL-C, but berberine shows better effect in lowering the level of TG and raising the level of HDL-C. In the treatment of hypertension, berberine with lifestyle intervention tended to lower the level of blood pressure more than the lifestyle intervention alone or placebo did; The same occurred when berberine combined with oral hypotensor was compared to the same hypotensor. Notably, no serious adverse reaction was reported in the 27 experiments. This study indicates that berberine has comparable therapeutic effect on type 2 DM, hyperlipidemia and hypertension with no serious side effect. Considering the relatively low cost compared with other first-line medicine and treatment, berberine might be a good alternative for low socioeconomic status patients to treat type 2 DM, hyperlipidemia, hypertension over long time period. Due to overall limited quality of the included studies, the therapeutic benefit of berberine can be substantiated to a limited degree. Better methodological quality, large controlled trials using standardized preparation are expected to further quantify the therapeutic effect of berberine. Copyright © 2014 Elsevier Ireland Ltd.

Antidotal activity of Averrhoa carambola (Star fruit) on fluoride induced toxicity in rats

PubMed Central

Vasant, Rupal A.

2014-01-01

Consumption of fluoride leads to several physiological disturbances in carbohydrate, lipid and antioxidant metabolisms. Averrhoa carambola L. fruit (Star fruit) is a commonly consumed fruit in tropical countries and is an ingredient in folklore medicines. As the fruits have high polyphenolic and antioxidant contents, the present study was undertaken to investigate the potential of star fruit as a dietary supplement in attenuating the fluoride induced hyperglycemia, hypercholesterolemia and oxidative stress in laboratory rats. A four-week exposure to fluoride caused sustained hyperglycemia, hyperlipidemia and oxidative stress and, when the diet was supplemented with star fruit powder, carbohydrate, lipid and antioxidant profiles were restored significantly. It is surmised that the antihyperglycemic, antihypercholesterolemic and antioxidant activities of star fruit in fluoride exposed rats could be due to the presence of polyphenols, flavonoids, saponins, phytosterols, ascorbic acid and fibers in the fruit, which are all well known regulators of carbohydrate, lipid and antioxidant metabolisms. These findings suggest that star fruit can be used as a dietary supplement in fluoride endemic regions to contain fluoride induced hyperglycemia, hyperlipidemia and oxidative stress. PMID:26109886

The results of ergometric examination of 316 patients with chronic coronary insufficiency and various types of hyperlipoproteinemia have shown a clear diminution of physical working capacity in patients with hyperlipidemia as compared to patients with hyperlipidemia as compared to patients in whom the lipid content is within normal values. Working capacity was most diminished in IIa and particularly IIb types of hyperlipoproteinemia; in type IV physical working capacity was not reduced. The effect of hyperlipoproteinemia is most significant in the mildest degree of coronary insufficiency, but reduces or vanishes completely with increasing severity of the disease. An inverse relationship has been established between the value of physical working capacity and the level of cholesterol and beta-lipoproteins and a direct relationship in regard to NEFA concentration. Ergometry in patients with type II hyperlipoproteinemia showed that as compared to patients with normolipemia and type IV hyperlipoproteinemia an equal degree in the severity of the disease, the frequency and marked character of changes on the ECG increase; this evidences a more marked transitory myocardial ischemia.

We sought to evaluate the associations between frequency of daily laughter with heart disease and stroke among community-dwelling older Japanese women and men. We analyzed cross-sectional data in 20 934 individuals (10 206 men and 10 728 women) aged 65 years or older, who participated in the Japan Gerontological Evaluation Study in 2013. In the mail-in survey, participants provided information on daily frequency of laughter, as well as body mass index, demographic and lifestyle factors, and diagnoses of cardiovascular disease, hyperlipidemia, hypertension, and depression. Even after adjustment for hyperlipidemia, hypertension, depression, body mass index, and other risk factors, the prevalence of heart diseases among those who never or almost never laughed was 1.21 (95% CI, -1.03-1.41) times higher than those who reported laughing every day. The adjusted prevalence ratio for stroke was 1.60 (95% CI, 1.24-2.06). Daily frequency of laughter is associated with lower prevalence of cardiovascular diseases. The association could not be explained by confounding factors, such as depressive symptoms.

3-Monochloropropane-1,2-diol (3-MCPD) esters have been detected in many foods, which have become a new safety issue worldwide. In the study, we investigated the effect of four 3-MCPD diesters (palmitate diester: CDP; stearate diester: CDS; oleate diester: CDO; linoleate diester: CDL) on lipid metabolism in C57BL/6J mice. The results showed that CDP, CDS, CDO and CDL significantly increased the serum TC, LDL-C levels and liver TG, TC levels at dose of 16.5μmol/kg/day. These results indicated that 3-MCPD diesters could potentially cause hyperlipidemia in C57BL/6J mice. Moreover, oil red O staining confirmed fat accumulation in liver induced by 3-MCPD diesters. Our work will provide more information for safety evaluation of 3-MCPD diesters. However, whether free 3-MCPD or free fatty acids or combined action compensates for the hyperlipidemia effects should be elucidated in the future. Copyright © 2015 Elsevier B.V. All rights reserved.

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.

Sangsawang, Tamon; Sriwijitkamol, Apiradee

2015-01-01

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.

The efficacy of evolocumab in the management of hyperlipidemia: a systematic review

Background: Hyperlipidemia or dyslipidemia has been a concern for a long time, with various guidelines emphasizing the importance of managing the lipid profile to prevent cardiac incidences. Although statins have been found to be highly effective, resistance and intolerability to side effects will continue to be a stumbling block for certain patients. Proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors tackle lipid profile via a novel mechanism and therefore provide an additional effective option for managing lipid profile. The overarching aim of this systematic review was to evaluate the efficacy of evolocumab among various populations with hypercholesterolemia. Methods: A comprehensive search was conducted in ProQuest Health & Medical Complete, Google Scholar, ScienceDirect, and PubMed to identify potential records; then titles, abstracts, and full texts were screened using the inclusion criteria to filter out irrelevant studies. Data extraction and quality assessment were undertaken using standardized tools and the results were narratively synthesized and presented in tables. Results: Eight studies were included in this systematic review after screening 1191 records. All studies demonstrated a statistically significant reduction in low-density lipoprotein cholesterol (LDL-C) values in the groups that received evolocumab compared with the comparator groups (p < 0.05). The decline in LDL-C levels from baseline in the majority of studies ranged from 40% to 80%, whether used alone or in combination with other agents. Also, high-density lipoprotein cholesterol, lipoprotein (a) and apolipoprotein B were improved with the use of evolocumab. Conclusions: This study helped to collate evidence from studies that tested the effectiveness of evolocumab in the management of hyperlipidemia. Evolocumab seems to be highly effective in reducing LDL-C and other lipid parameters. Hence, it provides an excellent alternative for patients with refractory disease or patients who develop intolerable side effects, therefore helping to overcome the stumbling block to achieving optimal lipid management.

Spleen removal may be recommended during organ transplantation in ABO-incompatible recipients as well as for hypoperfusion of the grafted liver, besides conventional surgical indications, but elevation of serum lipids has been observed in certain contexts. Aiming to analyze the influence of two dietary regimens on lipid profile, an experimental study was conducted. Male Wistar rats (n = 86, 333.0 +/- 32.2 g) were divided in four groups: group 1: controls; group 2: sham operation; group 3: total splenectomy; group 4: subtotal splenectomy with upper pole preservation; subgroups A (cholesterol reducing chow) and B (cholesterol-rich mixture) were established, and diet was given during 90 days. Total cholesterol (Tchol), high-density lipoprotein (HDL), low-density lipoprotein (LDL), very-low-density lipoprotein (VLDL), and triglycerides were documented. After total splenectomy, hyperlipidemia ensued with cholesterol-reducing chow. Tchol, LDL, VLDL, triglycerides, and HDL changed from 56.4 +/- 9.2, 24.6 +/- 4.7, 9.7 +/- 2.2, 48.6 +/- 11.1, and 22.4 +/- 4.3 mg/dL to 66.9 +/- 11.4, 29.9 +/- 5.9, 10.9 +/- 2.3, 54.3 +/- 11.4, and 26.1 +/- 5.1 mg/dL, respectively. Upper pole preservation inhibited abnormalities of Tchol, HDL, VLDL, and triglycerides, and LDL decreased (23.6 +/- 4.9 vs. 22.1 +/- 5.1, P = 0.002). Higher concentrations were triggered by splenectomy and cholesterol-enriched diet (Tchol 59.4 +/- 10.1 vs. 83.9 +/- 14.3 mg/dL, P = 0.000), and upper-pole preservation diminished without abolishing hyperlipidemia (Tchol 55.9 +/- 10.0 vs. 62.3 +/- 7.8, P = 0.002). After splenectomy, hyperlipidemia occurred with both diets. Preservation of the upper pole tended to correct dyslipidemia in modality A and to attenuate it in subgroup B. (c) 2008 Wiley-Liss, Inc.

Previous studies have examined an association between the siesta habit and hypertension, as well as coronary heart disease. However, the relationship between a siesta and the risk of rupture of an intracranial aneurysm (IA) has not yet been established. We aimed to investigate the effects of a siesta on the risk of rupture of IAs. We prospectively enrolled consecutive patients diagnosed with IAs at our hospital between January 2016 and December 2016. Univariate and multivariate logistic regression analysis were performed to identify independent risk factors associated with IA rupture. We studied 581 consecutive patients with 514 unruptured and 120 ruptured aneurysms. Univariate analysis demonstrated that hypertension, hyperlipidemia, diabetes mellitus, cigarette smoking, location, size, as well as shape and aspect ratio were associated with the risk of rupture of IAs. Multivariate analysis identified hypertension [odds ratio (OR) 1.68, 95% confidence interval (CI) 1.03-2.73], hyperlipidemia (OR 0.25, 95% CI 0.08-0.72), current cigarette smoking ≥20 cigarettes/day (d) (OR 3.48, 95% CI 1.63-7.47), siesta (siesta time <1 h, OR 0.49, 95% CI 0.24-0.98 and siesta time ≥1 h, OR 0.32, 95% CI 0.19-0.57), location of largest aneurysm on the anterior communicating and internal carotid-posterior communicating artery (PCOM) (anterior communicating artery OR 16.27, 95% CI 7.40-35.79 and PCOM OR 11.21, 95% CI 5.15-24.43), and size of aneurysm ≥7 mm (OR 2.19, 95% CI 1.21-3.97) as independent strong risk factors associated with risk of aneurysm rupture. In the present study, we found that a habitual siesta is a new predictive factor to assess the risk of rupture of an IA. We found the siesta habit may reduce the risk of aneurysm rupture. We also found that hypertension, hyperlipidemia, cigarette smoking, location, and size of aneurysm were associated with the risk of rupture of IAs.

Validation of the diabetes, hypertension and hyperlipidemia (DHL) knowledge instrument in Malaysia

PubMed Central

2012-01-01

Background Patient's knowledge on diabetes, hypertension and hyperlipidaemia and its medications can be used as one of the outcome measures to assess the effectiveness of educational intervention. To date, no such instrument has been validated in Malaysia. Therefore, the aim of this study was to evaluate the validity and reliability of the Diabetes, Hypertension and Hyperlipidemia (DHL) knowledge instrument for assessing the knowledge of patients with type 2 diabetes in Malaysia. Methods A 28-item instrument which comprised of 5 domains: diabetes, hypertension, hyperlipidemia, medications and general issues was designed and tested. One point was given for every correct answer, whilst zero was given for incorrect answers. Scores ranged from 0 to 28, which were then converted into percentage. This was administered to 77 patients with type 2 diabetes in a tertiary hospital, who were on medication(s) for diabetes and who could understand English (patient group), and to 40 pharmacists (professional group). The DHL knowledge instrument was administered again to the patient group after one month. Excluded were patients less than 18 years old. Results Flesch reading ease was 60, which is satisfactory, while the mean difficulty factor(SD) was 0.74(0.21), indicating that DHL knowledge instrument was moderately easy. Internal consistency of the instrument was good, with Cronbach's α = 0.791. The test-retest scores showed no significant difference for 26 out of the 28 items, indicating that the questionnaire has achieved stable reliability. The overall mean(SD) knowledge scores was significantly different between the patient and professional groups [74.35(14.88) versus 93.84(6.47), p < 0.001]. This means that the DHL knowledge instrument could differentiate the knowledge levels of participants. The DHL knowledge instrument shows similar psychometric properties as other validated questionnaires. Conclusions The DHL knowledge instrument shows good promise to be adopted as an instrument for assessing diabetic patients' knowledge concerning their disease conditions and medications in Malaysia.

Little is known about isolated diastolic hypertension (IDH) among different ethnicity groups. We aimed to investigate the prevalence and risk factors for IDH among the major ethnicity population i.e. Han, Uygur and Kazakh in Xinjiang, northwestern part of China. In total, 14,618 adult participants (7,799 males, 6,819 females) were recruited from the Cardiovascular Risk Survey conducted during 2007 and 2010. Blood pressure, body mass index and standard lipid profile and fasting glucose level from plasma were measured. The overall prevalence of IDH was 10.8% in the Han, 4.5% in the Uygur and 8.7% in the Kazakh populations. When stratified by gender, IDH prevalence was 9.8% in men and 6.8% in women (P<0.001). The prevalence of IDH also varied significantly with age and it was highest in those aged 35-44 yrs old (9.7%) and lowest in those over 75 yrs old (4.1%, P<0.001). Multivariate logistic regression analysis showed that overweight (OR = 1.179, 95%CI: 1.015-1.369) or obesity (OR = 1.202, 95%CI: 1.015-1.424), smoking (OR = 1.362, 95%CI: 1.156-1.604) and high total cholesterol (TC) hyperlipidemia (OR = 1.237, 95%CI: 1.074-1.423) were significantly associated with a higher prevalence of IDH. Identified risk factors for IDH differed among ethnicity groups with male gender, young age (35-44 yrs old), more coffee or tea consumption and high TC hyperlipidemia in the Han; smoking and often coffee or tea consumption in the Uygur and male gender and overweight or obesity in the Kazakh populations. IDH prevalence in the Han population is higher than that in the Uygur and Kazak populations in Xinjiang, northwestern part of China. Male gender, middle age, overweight or obesity, smoking and high TC hyperlipidemia appear to be relevant risk factors of IDH in adults. Different ethnicity background had different sets of risk factors for IDH.

We sought to evaluate the effect of cardiorespiratory fitness (CRF) in predicting mortality, myocardial infarction (MI), and revascularization in patients with hyperlipidemia after stratification by gender and statin therapy. This retrospective cohort study included 33,204 patients with hyperlipidemia (57 ± 12 years old, 56% men, 25% black) who underwent physician-referred treadmill stress testing at the Henry Ford Health System from 1991 to 2009. Patients were stratified by gender, baseline statin therapy, and estimated metabolic equivalents from stress testing. We computed hazard ratios using Cox regression models after adjusting for demographics, cardiac risk factors, comorbidities, pertinent medications, interaction terms, and indication for stress testing. There were 4,851 deaths, 1,962 MIs, and 2,686 revascularizations over a median follow-up of 10.3 years. In men and women not on statin therapy and men and women on statin therapy, each 1-metabolic equivalent increment in CRF was associated with hazard ratios of 0.86 (95% CI 0.85-0.88), 0.83 (95% CI 0.81-0.85), 0.85 (95% CI 0.83-0.87), and 0.84 (95% CI 0.81-0.87) for mortality; 0.93 (95% CI 0.90-0.96), 0.87 (95% CI 0.83-0.91), 0.89 (95% CI 0.86-0.92), and 0.90 (95% CI 0.86-0.95) for MI; and 0.91 (95% CI 0.88-0.93), 0.87 (95% CI 0.83-0.91), 0.89 (95% CI 0.87-0.92), and 0.90 (95% CI 0.86-0.94) for revascularization, respectively. No significant interactions were observed between CRF and statin therapy (P > .23). Higher CRF attenuated risk for mortality, MI, and revascularization independent of gender and statin therapy in patients with hyperlipidemia. These results reinforce the prognostic value of CRF and support greater promotion of CRF in this patient population. Copyright © 2015 Elsevier Inc. All rights reserved.

Efficacy and tolerability of adding coenzyme A 400 U/d capsule to stable statin therapy for the treatment of patients with mixed dyslipidemia: an 8-week, multicenter, double-Blind, randomized, placebo-controlled study

PubMed Central

2014-01-01

Background Patients with mixed hyperlipidemia usually are in need of combination therapy to achieve low-density lipoprotein cholesterol (LDL-C) and triglyceride (TG) target values for reduction of cardiovascular risk. This study investigated the efficacy and safety of adding a new hypolipidemic agent, coenzyme A (CoA) to stable statin therapy in patients with mixed hyperlipidemia. Methods In this multi-center, 8-week, double-blind study, adults who had received ≥8 weeks of stable statin therapy and had hypertriglyceridemia (TG level at 2.3-6.5 mmol/L) were randomized to receive CoA 400 U/d or placebo plus stable dosage of statin. Efficacy was assessed by the changes in the levels and patterns of lipoproteins. Tolerability was assessed by the incidence and severity of adverse events (AEs). Results A total of 304 patients with mixed hyperlipidemia were randomized to receive CoA 400 U/d plus statin or placebo plus statin (n = 152, each group). After treatment for 8 weeks, the mean percent change in TG was significantly greater with CoA plus statin compared with placebo plus statin (-25.9% vs -4.9%, respectively; p = 0.0003). CoA plus statin was associated with significant reductions in TC (-9.1% vs -3.1%; p = 0.0033), LDL-C (-9.9% vs 0.1%; p = 0.003), and non- high-density lipoprotein cholesterol (-13.5% vs -5.7%; p = 0.0039). There was no significant difference in the frequency of AEs between groups. No serious AEs were considered treatment related. Conclusions In these adult patients with persistent hypertriglyceridemia, CoA plus statin therapy improved TG and other lipoprotein parameters to a greater extent than statin alone and has no obviously adverse effect.

Overweight and obese individuals have increased health risks. Clinical reminders positively affect health outcomes in diabetes and osteoporosis, but the effect of automated prompts on weight loss in obesity has not been studied. Our objective was to determine whether an automatic prompt for the clinician to recommend lifestyle changes to patients with a body mass index (BMI) >25 kg/m(2) led to greater weight loss over a 3- to 6-month interval compared with the absence of a clinical reminder. We conducted a retrospective analysis of electronic medical records of obese adult patients with a BMI >25 kg/m(2) who were seen in 2009 and 2010, before and after implementation of an automated printed clinical reminder, respectively. We evaluated 1600 patients in each of the control and intervention groups. The primary outcome was the mean change in BMI between the control and intervention groups. Multiple linear regression was used to assess the effect of the clinical reminder on the change in BMI while adjusting for baseline BMI and potential confounding factors. The reduction in BMI (mean ± standard deviation) in the group with the clinical reminder (-0.084 ± 1.56 kg/m(2)) was not significantly greater than the control group (-0.053 ± 1.49 kg/m(2); P = .56). A regression model incorporating the clinical reminder, age, baseline BMI, obesity diagnosis, diabetes, and hyperlipidemia found that baseline BMI (P < .001), obesity diagnosis (P < .001), age (P = .001), and hyperlipidemia diagnosis (P = .02) were significant predictors of weight loss, but the clinical reminder was not (P = .78). There was a significant interaction between the clinical reminder and baseline BMI (P = .005), as the prompt increased weight loss more in those with lower baseline BMI. Automated clinical reminders alone do not improve weight loss in overweight and obese patients. Physician diagnoses of obesity or hyperlipidemia were associated with weight loss, suggesting that formally noting these diagnoses contributes to successful weight loss.

Objectives: The objective of this study is to develop an experimental model of hyperlipidemia and insulin resistance (IR), markers of coronary heart disease (CHD) using high fat and high sugar (HFHS) diet and to evaluate the efficacy of the model using atorvastatin, a known antihyperlipidemic drug, pioglitazone, a known insulin sensitizer, and Tinospora cordifolia (Tc), an antidiabetic plant. Materials and Methods: Following Institutional Animal Ethics Committee permission, the study was conducted in male Wistar rats (200-270 g). The model was developed using a high fat (vanaspati ghee: coconut oil, 3:1) oral diet along with 25% fructose (high sugar) added in drinking water over a period of 6 weeks. Atorvastatin (2.1 mg/kg/day), pioglitazone (2.7 mg/kg/day) and Tc (200 mg/kg/day) were administered 3 weeks after initiation of HFHS diet and continued for another 3 weeks. Parameters assessed were weight, lipid profile, fasting blood glucose, insulin, and gastric emptying. Serum malondialdehyde (MDA) and catalase were assessed as markers of oxidative stress. Results: Administration of HFHS diet demonstrated a significant increase in blood glucose, insulin, total and low density lipoprotein cholesterol and triglycerides with a decrease in high density lipoprotein cholesterol. Treatment with test drugs decreased blood sugar, insulin, lipid parameters, increased gastric emptying rate, decreased MDA levels, and catalase activity when compared to HFHS diet group, confirming the efficacy of the model. Atherogenic index of all the test drugs (0.48, 0.57, and 0.53) was significantly lower as compared to HFHS diet group (1.107). Conclusion: This study confirms the development of a diet based cost-effective and time efficient experimental model, which can be used to study two important markers of cardiovascular disease that is, hyperlipidemia and IR and to explore the efficacy of new molecules in CHD.

Little is known about the burden of rheumatoid arthritis (RA) in South Africa. The aim of this study was to establish the prevalence of RA and coexisting chronic disease list (CDL) conditions in the private health sector of South Africa. A retrospective, cross-sectional analysis was performed on medicine claims data from 1 January 2014 to 31 December 2014 to establish the prevalence of RA. The cohort of RA patients was then divided into those with and those without CDL conditions, to determine the number and type of CDL conditions per patient, stratified by age group and gender. A total 4352 (0.5%) patients had RA, of whom 69.3% (3016) presented with CDL conditions. Patients had a median age of 61.31 years (3.38; 98.51), and 74.8% were female. Patients with CDL conditions were older than those patients without (p < 0.001; Cohen's d = 0.674). Gender had no influence on the presence of CDL conditions (p = 0.456). Men had relatively higher odds for hyperlipidemia (OR 1.83; CI 1.33-2.51; p < 0.001) and lower odds for asthma (OR 0.83; CI 0.48-1.42; p = 0.490) than women. In combination with hyperlipidemia, the odds for asthma were reversed and strongly increased (OR 6.74; CI 2.07-21.93; p = 0.002). The odds for men having concomitant hyperlipidemia, hypertension, type 2 diabetes mellitus and hypothyroidism were insignificant and low (OR 0.40; CI 0.16-1.02; p = 0.055); however, in the absence of hypothyroidism, the odds increased to 3.26 (CI 2.25-4.71; p < 0.001). Hypothyroidism was an important discriminating factor for comorbidity in men with RA. This study may contribute to the body of evidence about the burden of RA and coexisting chronic conditions in South Africa.

The genetic component of dyslipidemia has been studied in adults but little in older population. It is remains unknown regarding influence and interaction of APOA5 gene single nucleotide polymorphism (SNP) and habitual aerobic exercise (HAE) on changes of blood lipids and lipoprotein phenotypes in older Chinese adults. Four-hundred-twenty-three old Chinese individuals with HAE were divided into hyperlipidemia and normal groups. We genotyped polymorphic loci using matrix assisted laser desorption ionization time of flight mass spectrometry detection technology (MALDI-TOF). HAE level was assessed by International Physical Activity Questionnaire (IPAQ) scale. For three genotypes of rs662799 site, the AG + GG gene carriers presented higher risk of hyperlipidemia compared to the AA carriers, with the ratio of 1.676 (P = .018, 95% CI: 1.092-2.571) for the AG and 1.812 (P = .002, 95% CI: 1.247-2.632) for the GG, respectively. The rs662799 G allele was significantly associated with lower HDL-C but higher TG levels. In relation to different HAE levels, less interaction was observed between the AA carriers and different HAE levels on corresponding lipids changes. The AG + GG carriers with higher HAE levels had significantly lower TG responses compared to those with lower HAE levels (1.45 ± 0.74 mmol/L vs. 1.86 ± 1.15 mmol/L). Excess risk for low HDL-C and hyperlipidemia was associated with rs662799 genotype alleles of APOA5 SNPs in older Chinese adults. Interaction of gene-HAE and HAE levels may induce different responses of blood lipids and lipoprotein phenotypes. HAE levels have less influence on TG changes in the AA carriers; however, high HAE levels appeared to greatly impact TG responses in the AG + GG carriers. Copyright © 2018.

To determine the effectiveness of an instant haw beverage in regulating lipid disturbance, enhancing antioxidant enzyme activity and immune function. Data was collected from 60 hyperlipidemic subjects. In this crossover design, each subject randomly received either the instant haw beverage (100 ml corresponding to 3 g of haw powder or 30 g of fresh haw fruit plus the carrier-guar gum plus some starch) or placebo (guar gum 1.5 g plus some starch as the carrier of the beverage) twice daily. Each supplementation lasted 31 days with a 28-day washout period between treatments. The instant haw beverage significantly reduced total serum cholesterol (9.6%), triglyceride (12.1%), LDLC (18%) while significantly increased SOD activities (7.5%). The placebo was shown to have positive results in some of the lipid profiles, though the effects of the instant haw beverage demonstrated greater significance. Serum triglyceride levels were significantly decreased and SOD activity significantly increased only as subjects were supplemented with the instant haw beverage while no significant changes were seen with placebo. Supplementation with the instant haw beverage positively affects blood lipid profile, antioxidant status and immune function in individuals with hyperlipidemia.

Despite increases in obesity and related diseases in developing nations, initial refugee clinical visits do not address these issues. We explored the development of obesity and related diseases in a longitudinal prospective cohort of African refugees resettling in northeastern US. Using state Department of Health data, refugees were linked to a health system. Body mass index, diabetes, hypertension, and hyperlipidemia status were extracted from charts. US regional controls from NAMCS/NHAMCS data were matched by age, sex, race, and visit year. African refugee BMI increased after resettlement at 1 (1.7 ± 2.9, p < 0.0001) and 5 years (3.1 ± 3.7, p < 0.0001), a different trend than matched regional controls (p = 0.01). Refugees had increased rates of diabetes (1.0 vs. 10.8 %, p < 0.0001), hypertension (16.7 vs. 21.6 %, p < 0.0001) and hyperlipidemia (3.9 vs. 10.8 %, p < 0.0001) at 5 years not observed in regional controls. Our findings emphasize the need for interventions during resettlement to prevent development of obesity and related disease in this vulnerable population.

Objective This study sought to examine the effect of ziprasidone on olanzapine or clozapine associated medical morbidity such as insulin resistance, diabetes mellitus and impaired fasting glucose, obesity and hyperlipidemia in patients with schizophrenia or schizoaffective disorder. Method This was a six-week, open label trial of ziprasidone 160 mg/day added to a stable dose of olanzapine or clozapine in twenty-one schizophrenia or schizoaffective patients with diabetes mellitus, impaired fasting glucose, or insulin resistance. Results Ten olanzapine-treated subjects and eleven clozapine-treated subjects were enrolled in the study. There were no significant differences between the two groups at baseline for age, gender, education, ethnicity, BMI, cholesterol levels, or fasting glucose. At week six, there were no significant changes in weight, BMI, cholesterol levels, or fasting glucose. There was no significant difference in psychotic, negative or depressive symptoms. QTc significantly increased at week 2 but not at week 6. Conclusions The addition of 160 mg/day of ziprasidone was well tolerate but did not produce significant improvement in fasting glucose, insulin resistance, hyperlipidemia or lead to weight loss in olanzapine- or clozapine-treated subjects with schizophrenia or schizoaffective disorder.

We describe a patient with hypothyroidism displaying "dropped head" syndrome. A 50-year-old man visited our clinic because he was unable to hold his head in the natural position. He had weakness and hypertrophy of the neck extensor muscles. Tendon reflexes were diminished or absent in all limbs. Mounding phenomena were observed in the bilateral upper extremities. Blood biochemical analysis revealed hypothyroidism, hyperlipidemia, and elevated levels of muscle-derived enzymes. Magnetic resonance imaging (MRI) of the neck demonstrated swelling and hyperintensity of the neck extensor muscles on T2-weighted images. The result of biopsy of the right biceps brachii muscle suggested mild atrophy of type 2 fibers. The diameters of the muscle fibers exhibited mild variation. No inflammatory changes were observed. We diagnosed hin as having "dropped head" syndrome due to hypothyroidism. Administration of thyroid hormone agent gradually improved his condition, and he became able to hold his head in the natural position. Levels of muscle-derived enzymes normalized and his hyperlipidemia remitted. Neck MRI also revealed improvement. Our findings suggest that hypothyroidism should be considered in the differential diagnosis of "dropped head" syndrome, although only a few cases like ours have been reported.

Obesity is related to hyperlipidemia and risk of cardiovascular disease. Health benefits of vegetarian diets have well-documented in the Western countries where both obesity and hyperlipidemia were prevalent. We studied the association between BMI and various lipid/lipoprotein measures, as well as between BMI and predicted coronary heart disease probability in lean, low risk populations in Southern China. The study included 170 Buddhist monks (vegetarians) and 126 omnivore men. Interaction between BMI and vegetarian status was tested in the multivariable regression analysis adjusting for age, education, smoking, alcohol drinking, and physical activity. Compared with omnivores, vegetarians had significantly lower mean BMI, blood pressures, total cholesterol, low density lipoprotein cholesterol, high density lipoprotein cholesterol, total cholesterol to high density lipoprotein ratio, triglycerides, apolipoprotein B and A-I, as well as lower predicted probability of coronary heart disease. Higher BMI was associated with unfavorable lipid/lipoprotein profile and predicted probability of coronary heart disease in both vegetarians and omnivores. However, the associations were significantly diminished in Buddhist vegetarians. Vegetarian diets not only lower BMI, but also attenuate the BMI-related increases of atherogenic lipid/ lipoprotein and the probability of coronary heart disease.

Diabetic encephalopathy is one of the severe complications in patients with diabetes mellitus. Findings indicate that saffron extract has antioxidant properties but its underlying beneficial effects on diabetic encephalopathy were unclear. In the present study, the protective activities of saffron were evaluated in diabetic encephalopathy. Saffron at 40 and 80 mg/kg significantly increased body weight and serum TNF-α and decreased blood glucose levels, glycosylated serum proteins, and serum advanced glycation endproducts (AGEs) levels. Furthermore, significant increase in HDL and decrease (P < 0.05) in cholesterol, triglyceride, and LDL were observed after 28 days of treatment. At the end of experiments, the hippocampus tissue was used for determination of glutathione content (GSH), superoxide dismutase (SOD), and catalase (CAT) activities. Furthermore, saffron significantly increased GSH, SOD, and CAT but remarkably decreased cognitive deficit, serum TNF-α, and induced nitric oxide synthase (iNOS) activity in hippocampus tissue. Our findings indicated that saffron extract may reduce hyperglycemia and hyperlipidemia risk and also reduce the oxidative stress in diabetic encephalopathy rats. This study suggested that saffron extract might be a promising candidate for the improvement of chemically induced diabetes and its complications. PMID:25114929

Accumulation of unsaturated lipids in monocytes during early phase pyrogen tolerance.

This paper presents data that inspired a new explanation for the mechanism of early phase endotoxin tolerance. Rabbits injected intravenously with LPS from Salmonella abortus developed a two-phase fever (6 h) and monophasic hyperlipidemia of very low density lipoproteins (two consecutive days). If during these days rabbits were injected with the same dose of LPS at 24-h intervals, the second phase of fever disappeared, i.e. early phase pyrogenic tolerance was obtained. This was correlated with a decrease of lipoprotein hyperlipidemia (measured 1.5 h after LPS injection) and an accumulation of lipids rich in double bonds in monocytes (measured 3.5 h after LPS injection). Results showed that the degree of unsaturation of acyl chains (AC) in monocytes (AC/DB, DB=double bonds) is negatively correlated (r=-0.72) with fever response (fever index). The authors maintain that a gradual increase in monocyte membrane fluidity is an adaptation to repeated exposure of monocytes to lipid A and is responsible for the progressive desensitization of monocytes to endotoxin. It is suggested that disorders of this mechanism lead to an accumulation of abnormal quantities of saturated lipids and cholesterol within macrophages, which, as foam cells, are the starting point for atherosclerosis pathology.

The prevalence of obesity is high in older adults. Alcalase potato protein hydrolysate (APPH), a nutraceutical food, might have greater benefits and be more economical than hypolipidemic drugs. In this study, serum lipid profiles and heart protective effects were evaluated in high fat diet (HFD) induced hyperlipidemia in aging rats treated with APPH (15, 45 and 75 mg/kg/day) and probucol (500 mg/kg/day). APPH treatments reduced serum triacylglycerol (TG), total cholesterol (TC), and low density lipoprotein (LDL) levels to the normal levels expressed in the control group. Additionally, the IGF1R-PI3K-Akt survival pathway was reactivated, and Fas-FADD (Fas-associated death domain) induced apoptosis was inhibited by APPH treatments (15 and 45 mg/kg/day) in HFD aging rat hearts. APPH (75 mg/kg/day) rather than probucol (500 mg/kg/day) treatment could reduce serum lipids without affecting HDL expression. The heart protective effect of APPH in aging rats with hyperlipidemia was through lowering serum lipids and enhancing the activation of the compensatory IGF1R-PI3K-Akt survival pathway.

Super morbid obesity (body mass index [BMI] > 50 kg/m 2 ) is associated with significant comorbidities and is disparagingly prevalent among the black population. There is paucity of data regarding bariatric surgery outcomes among super morbid obese (SMO) blacks. Our aim is to evaluate the reduction in weight and resolution of comorbidities after bariatric surgery among SMO black patients at an urban academic institution. A retrospective review of SMO black patients who underwent bariatric surgery from August 2008 to June 2013 at Howard University Hospital. Outcomes of interest include weight loss, improvement or resolution of hypertension, type 2 diabetes, and hyperlipidemia at 12 months. Eighty-seven patients met our inclusion criteria. Mean preoperative weight and BMI were 347.2 lbs and 56.8 kg/m 2 , respectively. At 12 months, mean weight and BMI were 245.3 lbs and 40.1 kg/m 2 , respectively. There was also significant improvement or resolution of hypertension, type 2 diabetes, and hyperlipidemia. Bariatric surgery may result in significant weight loss and improvement or resolution of comorbidities in SMO black patients. Copyright © 2016. Published by Elsevier Inc.

Dyslipidemia is a component of the metabolic syndrome, an established risk factor for atherosclerotic cardiovascular disease, and is also observed in various autoimmune and chronic inflammatory conditions. However, there are limited opportunities to study the impact of acquired dyslipidemia on cardiovascular and immune pathology. We designed a model system that allows for the conversion to a state of acute hyperlipidemia in adult life, so that the consequences of such a transition could be observed, through conditionally deleting APOE (apolipoprotein E) in the adult mouse. The transition to hypercholesterolemia was accompanied by adaptive immune responses, including the expansion of T lymphocyte helper cell 1, T follicular helper cell, and T regulatory subsets and the formation of germinal centers. Unlike steady-state Apoe -deficientmice, abrupt loss of APOE induced rapid production of antibodies recognizing rheumatoid disease autoantigens. Genetic ablation of the germinal center reduced both autoimmunity and atherosclerosis, indicating that the immune response that follows loss of APOE is independent of atherosclerosis but nevertheless promotes plaque development. Our findings suggest that immune activation in response to hyperlipidemia could contribute to a wide range of inflammatory autoimmune diseases, including atherosclerosis. © 2018 American Heart Association, Inc.

The present study was designed to investigate the effects of hyperlipidemia on the cerebral lipids, vessels and neurons of rats, and to provide experimental evidence for subsequent intervention. One hundred adult SD rats, half of which were male and half of which were female, were randomly divided into five groups on the basis of serum total cholesterol (TC) levels. Four groups were fed a hypercholesterolemic diet (rat chow supplemented with 4% cholesterol, 1% cholic acid and 0.5% thiouracil - this is also called a CCT diet) for periods of 1 week, 2 weeks, 3 weeks and 4 weeks, respectively. A control group was included. The levels of serum lipids, cerebral lipids, free fatty acids (FFA), interleukin-6 (IL-6), interleukin-1 (IL-1), tumor necrosis factor alpha (TNF-α), vascular endothelial growth factor (VEGF), oxidized low density lipoprotein (ox-LDL), A-beta precursor proteins (APP), amyloid beta (Aβ), glial fibrillary acidic protein (GFAP) and tight junction protein Claudin-5 were measured after the experiment. The pathologic changes and apoptosis of the rat brains were evaluated. Compared with the control group, after 1 week of a CCT diet, the levels of serum total cholesterol (TC), triglycerides (TG), low density lipoprotein cholesterol (LDL-C) and brain triglycerides had increased by 2.40, 1.29 and 1.75 and 0.3 times, respectively. The serum high density lipoprotein cholesterol (HDL-C) had decreased by 0.74 times (P < 0.05) and the expression of IL-1, TNF-α and GFAP in the brains had increased (P < 0.05). In the second week, the expression of FFA and APP in the brains, and the amount of apoptotic neurons, had increased (P < 0.05). In the third week, the levels of VEGF, Ox-LDL and Aβ had increased, and the expression of Claudin-5 had decreased in the brains (P < 0.05). In the fourth week, the levels of TC, LDL-C and the amount of apoptotic neurons had increased (P < 0.05). The correlation analysis showed a positive correlation among FFA, TNF-α, VEGF, ox-LDL, Aβ, GFAP and neuronal apoptosis in the rat brains, and they all were negatively correlated with Claudin-5 (P < 0.05). Hyperlipidemia may activate astrocytes by means of high levels of TG that will have direct toxic effects on the cerebral vessels and neurons by causing the secretion of TNF-α and IL-1 in the brains of rats. In the metabolic procession, brain tissue was shown to generate FFA that aggravated the biosynthesis of ox-LDL. With the extension of the duration of hyperlipidemia, high levels of cerebral TC and LDL-C were shown to aggravate the deposition of Aβ, induce the secretion of VEGF, reduce the expression of tight junction protein Claudin-5 and change the permeability of blood-brain barriers to factors that could damage cerebral vessels and neurons.

Objective: The burden of chronic disease has been continuously increasing in China since the early 1980s. Besides the worsening of risk factors, the change in diagnostic criteria is very likely an important explanation for the increase in the prevalence of hypertension, hyperlipidemia and diabetes mellitus, three commonest, major chronic conditions that can lead to major vascular events and deaths. This study aims to estimate the contribution of changes in diagnostic criteria to the increase in the prevalence of the three conditions in China. Methods: The data from two representative nation-wide surveys in China in 2002 and 2009, with 145 254 and 8 813 adults included respectively, were used to estimate the prevalence rate of the three conditions and the proportion attributable to the change in diagnostic criteria around year 2000. The new and old cutoff values for hypertension, hyperlipidemia, and hyperglycemia were 140/90 and 160/95 mmHg (1 mmHg=0.133 kPa), 5.7 and 6.2 mmol/L, and 7.0 and 7.8 mmol/L, respectively. The prevalence was standardized according to the distribution of age, sex and rural-urban residence of the 2000 national census of the country so as to compare between the old and new diagnostic criteria and project the situation for the entire country. Results: The standardized prevalence of hypertension, hyperlipidemia, and diabetes mellitus for the entire Chinese adult population in 2002 was 8.21%, 1.71% and 1.43% according to the immediate previous diagnostic criteria, and 19.18%, 3.53% and 2.66% according to the new criteria. In 2009, the prevalence was 11.89%, 9.34% and 4.29% according to the old criteria, and 24.78%, 18.36% and 6.55% according to the new criteria. The total cumulative prevalence of the three conditions was increased by 124% in 2002 and 95% in 2009 as a result of change in diagnostic criteria. Put it differently, the change in diagnostic criteria increased the number of the three conditions from 2002 to 2009 by approximately 359 million and could increase the annual drug costs by some 271 billion RMB if all the conditions are treated. The drug costs alone of treating all the three conditions could consume 56% of the total health budget of the Government in 2010. Conclusion: About half of the number of the three conditions is a result of the change in diagnostic criteria. These criteria were adopted from western populations, which are designed to meet the population need and suit healthcare resources available in these countries. It is important for China to consider the resources available and needs and values of the population in addition to the benefits, harms and costs of treatment in determining the cutoff values for defining these conditions for drug interventions.

The aims of this study were to evaluate the effect of poloxamer 407 administration on atherogenic serum lipoprotein fractions and subfractions associated with cholesterol, triglycerides and phospholipids, as well as the onset of early atherosclerosis, in mice. Mice were administered either sterile saline or poloxamer 407 (to induce a dose-controlled hyperlipidemia) for 1 month and then sacrificed at 1, 4 and 10 days after the last dose of poloxamer 407. Systolic and diastolic blood pressure, the activity of a cysteine protease (cathepsin B) in cardiac and liver tissue, and histological/morphological examination of heart and liver specimens was performed for each group of mice at each time point. Lastly, small angle X-ray scattering was utilized to analyze the lipoprotein fractions and subfractions associated with cholesterol, triglycerides and phospholipids for both groups of mice at each time point. Statistical analysis was performed using one-way, analysis-of-variance with post hoc analysis to determine significantly different mean values, while correlation analysis employed the Spearman test. Poloxamer 407-treated mice revealed significant hyperlipidemia, moderately elevated blood pressure, general lipidosis in liver cells, increased cysteine protease activity in heart tissue, and contractile-type changes in cardiomyocytes. Similar to humans, the onset of atherosclerosis in poloxamer 407-treated mice was characterized by a steady increase in serum low-density, intermediate-density and very-low-density lipoprotein fractions, as well as very-low-density lipoprotein subfractions. We would propose that the sustained elevation of serum atherogenic lipoprotein fractions and subfractions induced by the administration of poloxamer 407 to mice resulted in the morphological changes we observed in both heart and liver cells, which are suggested to precede atherosclerosis, since this is a well-established mouse model of atherosclerosis. Since most of the cellular, biochemical and physiological changes documented in the present study using poloxamer 407-treated mice are related to the symptoms of early atherosclerosis in humans, it is suggested that the poloxamer 407-induced mouse model of hyperlipidemia and atherosclerosis might prove beneficial as an experimental animal model with which to evaluate the pathological features observed in early-stage atherosclerosis.

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: NCT01256476.

Atomic bomb (A-bomb) radiation is associated with cardiovascular disease (CVD) and metabolic CVD risk factors. Chronic kidney disease (CKD) is also known to be a risk factor for CVD and little is known whether CKD is associated with A-bomb radiation. To examine whether CKD is associated with CVD risk factors or with A-bomb radiation in A-bomb survivors, we classified renal dysfunction in 1,040 A-bomb survivors who were examined in 2004-2007 as normal [n = 121; estimated glomerular filtration rate (eGFR) ≥ 90 ml/min/1.73 m(2)]; mild (n = 686; eGFR 60-89 ml/min/1.73 m(2)); moderate (n = 217; eGFR 30-59 ml/min/1.73 m(2)); or severe (n = 16; eGFR <30 ml/min/1.73 m(2)). Also, we diagnosed subjects in the moderate and severe renal dysfunction groups as having CKD (n = 233; eGFR <59 ml/min/1.73 m(2)). After adjusting for age, gender, and smoking and drinking habits, we looked for an association between renal dysfunction and hypertension, diabetes mellitus (DM), hyperlipidemia, and metabolic syndrome (MetS), and between renal dysfunction and A-bomb radiation. Hypertension [odds ratio (OR), 1.57; 95% confidence interval (CI), 1.12-2.20, P = 0.009]; DM (OR, 1.79; 95% CI, 1.23-2.61, P = 0.002); hyperlipidemia (OR, 1.55; 95% CI, 1.12-2.14, P = 0.008); and MetS (OR, 1.86; 95% CI, 1.32-2.63, P < 0.001) were associated with CKD (moderate/severe renal dysfunction), and hyperlipidemia and MetS were also associated with mild renal dysfunction. CKD (OR/Gy, 1.29; 95% CI, 1.01-1.63, P = 0.038) and severe renal dysfunction (OR/Gy, 3.19; 95% CI, 1.63-6.25, P < 0.001) were significantly associated with radiation dose. CKD associated with radiation may have played a role in the development of CVD among A-bomb survivors.

Hyperlipidemia is a major risk factor for coronary heart disease. Hyperlipidemia increases the incidence of myocardial ischemia and cardiac events. This study evaluated the potential hypolipidemic and antioxidant action of the aqueous extract from the uneaten pulp of the fruit from Cordia dichotoma ("CDNP extract"). In vivo studies were performed for 10 weeks on dietary hyperlipidemic and healthy Wistar albino rat models that received two dose levels of the CDNP extract (0.50 and 1.00 g/kg body weight). Serum lipid profiles were determined for the experimental animals. Dietary hyperlipidemic rats were characterized by an elevated lipid profile compared to the healthy control, i.e., increased levels of serum total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), very low density lipoprotein cholesterol (VLDL-C), and triglycerides (TG), although the level of high-density lipoprotein (HDL-C) was reduced. Levels of antioxidant enzymes, i.e., glutathione reductase (GR), glutathione peroxidase (GPx), glutathione-S-transferase (GST), superoxide dismutase (SOD), and catalase (CAT), were significantly higher in the dietary hyperlipidemic rats than in the normal healthy ones, while the level of malondialdehyde (MDA) was significantly lower. Force-feeding hyperlipidemic Wistar albino rats with the CDNP extract at two doses decreased TC, LDL-C, VLDL-C, and TG to normal levels. The risk ratio, which was as high as 870 % for the hyperlipidemic rats was decreased by the treatment to levels close to that calculated for the healthy control rats. Levels of high-density lipoprotein cholesterol (HDL-C) were very low in the hyperlipidemic Wistar albino rats but increased significantly when CDNP extract was adminstered, attaining similar HDL-C levels to those of healthy control rats. Treatment with the CDNP extract also improved the levels of antioxidant enzymes (GR, GST, GPx, SOD, and CAT) in hyperlipidemic Wistar albino rats. Thus, the CDNP extract improves the lipid metabolism of healthy and hyperlipidemic Wistar albino rats and can be employed in the management of dietary hyperlipidemia.

Previous studies have suggested that for clinical purposes, subjects with fasting triglycerides (TGs) between 89-180 mg/dl (1-2 mmol/l) would benefit from postprandial TGs testing. To determine the postprandial TG response in 2 independent studies and validate who should benefit diagnostically from an oral-fat tolerance test (OFTT) in clinical practice. A population of 1002 patients with coronary heart disease (CHD) from the CORDIOPREV clinical trial and 1115 white US subjects from the GOLDN study underwent OFTTs. Subjects were classified into 3 groups according to fasting cut points of TGs to predict the usefulness of OFTT: (1) TG < 89 mg/dl (<1 mmol/l); (2) TG, 89-180 mg/dl (1-2 mmol/l); and (3) TG > 180 mg/dl (>2 mmol/l). Postprandial TG concentration at any point > 220 mg/dl (>2.5 mmol/l) has been pre-established as an undesirable postprandial response. Of the total, 49% patients with CHD and 42% from the general population showed an undesirable response after the OFTT. The prevalence of undesirable postprandial TG in the CORDIOPREV clinical trial was 12.8, 50.3, and 89.7%, in group 1, 2, and 3, respectively (P < .001) and 11.2, 58.1, and 97.5% in group 1, 2, and 3, respectively (P < .001) in the GOLDN study. These two studies validate the predictive values reported in a previous consensus. Moreover, the findings of the CORDIOPREV and GOLDN studies show that an OFTT is useful to identify postprandial hyperlipidemia in subjects with fasting TG between 1-2 mmol/l (89-180 mg/dL), because approximately half of them have hidden postprandial hyperlipidemia, which may influence treatment. An OFTT does not provide additional information regarding postprandial hyperlipidemia in subjects with low TG (<1 mmol/l, <89 mg/dL) or increased TG (>2 mmol/l, >180 mg/dl).

To observe the clinical effect and efficacy of Xiaozhi Capsule (XZC), a Chinese medicine preparation for tonifying Gan-Shen, invigorating Pi to dissipate dampness (TGSIPDD) on total cholesterol (TC), triglyceride (TG), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), and endothelin (ET) in treating patients with hyperlipidemia. Totally 120 primary hyperlipidemia patients were randomly assigned to the treatment group (80 cases) and the control group (40 cases). Those in the treatment group took XZC, while those in the control group took Xuezhikang Capsule (XZKC). The serum TC, TG, HDL-C, LDL-C, and ET were detected and evaluated after 8 weeks of treatment. In the treatment group TC was reduced by 25.60%, TG by 33.70%, LDL-C by 32.90%, and ET by 11.02%, while HDL-C was elevated by 24.20%. In the control group, TC was reduced by 24.80%, TG by 33.50%, LDL-C by 31.30%, and ET by 12.05%, while HDL-C was elevated by 20.90%. There was statistical difference in the two groups when compared with before treatment (P < 0.01). But there was no statistical difference in the aforesaid indices between the two groups after treatment (P > 0.05). The integrals for main symptoms after treatment obviously decreased in the two groups, showing statistical difference when compared with before treatment in the same group (P < 0.01). But there was no statistical difference in the aforesaid indices between the two groups (P > 0.05). After 8 weeks of treatment, symptoms such as vertigo, heavy sensation of head, palpitation, chest distress, dry mouth and thirsty were obviously improved after treatment. There was statistical difference in the improvement of tinnitus after treatment in the treatment group (P < 0.01). The total effective rate was 86.25% in the treatment group and 82.50% in the control group, showing no statistical difference (P > 0.05). XZC showed certain effects on each blood lipid index and ET of hyperlipidemia patients. It had better improvement of clinical symptoms with reliable efficacy.

To investigate behavioral changes in a rat hyperlipidemia model induced by high lipid feed combined with depression by Chronic Unpredictable Mild Stress (CUMS). A total of 40 rats were randomly divided into control (CON), control feed for 9 weeks followed by CUMS for 4 weeks (CON + CUMS), high fat diet (HFD) and high lipid feed for 9 weeks followed by CUMS for 4 weeks (HFD + CUMS) (n = 10 each). Open-field test was individually measured at baseline, week 9 and week 13. (1) Serum lipids: total cholesterol [(2.67 ± 0.04) mmol/L, (2.68 ± 0.02) mmol/L] and low density lipoprotein [(1.08 ± 0.03) mmol/L, (1.06 ± 0.01) mmol/L] of HFD and HFD + CUMS were both significantly higher than those of CON and CON + CUMS [(1.78 ± 0.12) mmol/L, (0.79 ± 0.04) mmol/L; (1.76 ± 0.09) mmol/L, (0.76 ± 0.06) mmol/L, all P < 0.01]. (2) Open-field test: at week 13, compared to CON rats, CON + CUMS rats exhibited enhanced locomotor activity during the first minute, reduced activity in the center squares and rearing, and increased the number of grooming and defecation (all P < 0.05). In comparison to the CON rats, a decrease in total squares in 5 min, central squares and peripheral squares was observed in HFD rats at week 13 (all P < 0.05). However, compared with HFD, CON, CON + CUMS rats, when high lipid feed for 9 weeks combined with depression, significant decrease activities in total squares in 5 min, central squares and peripheral squares were observed in HFD + CUMS rats at week 13. Besides these, the number of rearing was reduced, however, locomotor activity during the first minute and the number of grooming and defecation was significantly increased (all P < 0.001). Under uncontrolled hyperlipidemia, severe depressive symptoms will present more early once exposure to a series of chronic stressors followed by significant autonomic nervous dysfunctional symptoms.

Hyperlipidemia may lead to endothelial injury, due to its effects on homocysteine and vascular endothelial growth factor in the serum, and the mRNA expression levels of peroxisome proliferator-activated receptor-γ (PPARγ), and caspase-3 and -8 in the vascular wall. In order to prevent and mitigate the high-fat state that results from endothelial injury, this study examined the effect of folic acid (FA) and vitamin B12 (VB12) on the expression of PPARγ and caspase-3 and -8 mRNA in the abdominal aortas of rats with hyperlipidemia. Sixty 4-week-old healthy male Sprague Dawley rats were randomly divided into five groups (each n=12): the normal control (NC), high-fat diet (HL), FA, VB12 and FA+VB12 groups. Following one week of adaptive feeding, the FA, VB12 and FA+VB12 groups were subject to the intraperitoneal injection of FA (0.5 mg/day), VB12 (0.05 mg/day) and FA+VB12 (0.5 mg/day and 0.05 mg/day), respectively, while fed a high-fat diet. The rats in the NC group were injected intraperitoneally with 0.9% NaCl solution (0.5 ml/day) and fed a normal diet, whereas those in the HL group were fed a high-fat diet only. A reverse transcription-polymerase chain reaction (RT-PCR) assay demonstrated that at the end of week 12, the FA treatment had effectively increased the PPARγ mRNA level, while reducing the caspase-3 and -8 mRNA levels, compared with the high-fat diet treatment (P<0.05). The effect of FA on the expression of PPARγ and caspase-3 and -8 was enhanced when used in combination with VB12 (P<0.05). These results revealed that the application of FA, alone or in combination with VB12, improves and mitigates the high-fat state that results from endothelial injury. PMID:23935743

Abstract To investigate the risk of nonarteritic anterior ischemic optic neuropathy (NAION) following end-stage renal disease (ESRD). A retrospective, nationwide, matched cohort study. ESRD patients identified by the International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) code 585. The study cohort included 93,804 ESRD patients registered with the Taiwan National Health Insurance Research Database between January 2000 and December 2009. An age- and sex-matched control group comprised 93,804 patients (case:control = 1:1) selected from the Taiwan Longitudinal Health Insurance Database 2000. Information for each patient was collected from the index date until December 2011. The incidence and risk of NAION were compared between the ESRD and control groups. The adjusted hazard ratio (HR) for NAION after adjustment for potential confounders was obtained by a Cox proportional hazard regression analysis. A Kaplan–Meier analysis was used to calculate the cumulative incidence rate of NAION. The incidence of NAION following ESRD. In total, 133 ESRD patients (0.14%) and 51 controls (0.05%) had NAION (P < 0.001) during the follow-up period, leading to a significantly elevated risk of NAION in the ESRD patients compared with the controls (incidence rate ratio = 3.14, 95% confidence interval [CI] = 2.11–4.67). After adjustment for potential confounders including diabetes mellitus, hypertension, hypotension, hyperlipidemia, and 2-way interaction terms between any 2 factors, ESRD patients were 3.12 times more likely to develop NAION than non-ESRD patients in the full cohort (adjusted HR = 3.12, 95% CI = 2.10–4.64). Additionally, patients with hypertension and hyperlipidemia showed higher incidence rates of NAION in the ESRD group compared with the controls: 2.31 (95% CI = 1.40–3.82) for hypertension and 2.72 (95% CI = 1.14–6.50) for hyperlipidemia. ESRD increased the risk of NAION, which is an interdisciplinary emergency. Close collaboration between nephrologists and ophthalmologists is important in NAION management following ESRD to prevent fellow eye involvement. PMID:27015205

Toward a human-centered hyperlipidemia management system: the interaction between internal and external information on relational data search.

PubMed

Gong, Yang; Zhang, Jiajie

2011-04-01

In a distributed information search task, data representation and cognitive distribution jointly affect user search performance in terms of response time and accuracy. Guided by UFuRT (User, Function, Representation, Task), a human-centered framework, we proposed a search model and task taxonomy. The model defines its application in the context of healthcare setting. The taxonomy clarifies the legitimate operations for each type of search task of relational data. We then developed experimental prototypes of hyperlipidemia data displays. Based on the displays, we tested the search tasks performance through two experiments. The experiments are of a within-subject design with a random sample of 24 participants. The results support our hypotheses and validate the prediction of the model and task taxonomy. In this study, representation dimensions, data scales, and search task types are the main factors in determining search efficiency and effectiveness. Specifically, the more external representations provided on the interface the better search task performance of users. The results also suggest the ideal search performance occurs when the question type and its corresponding data scale representation match. The implications of the study lie in contributing to the effective design of search interface for relational data, especially laboratory results, which could be more effectively designed in electronic medical records.

This study aimed to investigate the impairment of pancreatic endocrine function and the associated risk factors after acute pancreatitis (AP). Fifty-nine patients were subjected to tests of pancreatic function after an attack of pancreatitis. The mean time after the event was 3.5 years. Pancreatic endocrine function was evaluated by fasting blood glucose (FBG), glycosylated hemoglobin, fasting blood insulin, and C-peptide. Homeostasis model assessment was used to evaluate insulin resistance and islet β-cell function. Pancreatic exocrine function was evaluated by fecal elastase 1. Factors that could influence endocrine function were also investigated. Nineteen patients (32%) were found to have elevated FBG, whereas 5 (8%) had abnormal glycosylated hemoglobin levels. The levels of FBG, fasting blood insulin, and C-peptide were higher in patients than in controls (P < 0.01). The islet β-cell function of patients was lower than that of controls (P < 0.01), whereas insulin resistance index was higher among patients (P < 0.01). Obesity, hyperlipidemia, and diabetes-related symptoms were found to be associated with endocrine insufficiency. Pancreatic exocrine functional impairment was found at the same time. Endocrine functional impairment with insulin resistance was found in patients after AP. Obesity, hyperlipidemia, and diabetes-related symptoms increased the likelihood of developing functional impairment after AP.

This study aimed to investigate the effectiveness of monotherapy aspirin and warfarin for stroke prevention in low-risk atrial fibrillation (AF) by using a population-based cohort study in Taiwan. A newly diagnosed low-risk AF patient cohort were identified by using National Health Insurance Research Database (NHIRD) in Taiwan in 2008. The study cohort was observed with a follow-up of 2 years to examine the onset of ischemic stroke (IS) (to 2010). The longitudinal data were analyzed by using generalized estimation equations (GEE). A total of 8,065 newly-diagnosed low-risk AF patients were identified in 2008. 7.4% were prescribed with aspirin and 4.6% were prescribed with warfarin. The GEE results showed that low-risk AF patients with hypertension who received warfarin were associated with a statistically significant 58.4% reduction of IS risk (OR = 0.416, p = 0.024, 95% CI 0.194-0.891). Additionally, low-risk AF patients with hyperlipidemia who received warfarin were associated with a 69.3% reduction of IS risk (OR = 0.307, p = 0.044, 95% CI 0.097-0.969). Warfarin is suggested to be prescribed in preventing ischemic stroke for low-stroke-risk atrial fibrillation patients with hypertension and hyperlipidemia.

Metabolic syndrome is associated with several disorders, including hypertension, diabetes, hyperlipidemia as well as cardiovascular diseases and stroke. Plant-derived polyphenols, compounds found in numerous plant species, play an important role as potential treatments for components of metabolic syndrome. Studies have provided evidence for protective effects of various polyphenol-rich foods against metabolic syndrome. Fruits, vegetables, cereals, nuts, and berries are rich in polyphenolic compounds. Grapes (Vitis vinifera), especially grape seeds, stand out as rich sources of polyphenol potent antioxidants and have been reported helpful for inhibiting the risk factors involved in the metabolic syndrome such as hyperlipidemia, hyperglycemia, and hypertension. There are also many studies about gastroprotective, hepatoprotective, and anti-obesity effects of grape polyphenolic compounds especially proanthocyanidins in the literature. The present study investigates the protective effects of grape seeds in metabolic syndrome. The results of this study show that grape polyphenols have significant effects on the level of blood glucose, lipid profile, blood pressure, as well as beneficial activities in liver and heart with various mechanisms. In addition, the pharmacokinetics of grape polyphenols is discussed. More detailed mechanistic investigations and phytochemical studies for finding the exact bioactive component(s) and molecular signaling pathways are suggested.

To investigate the effect of ganoderma lucidum polysaccharides on blood lipid and lipoperoxidation from the experimental hyperlipidemic rats. 50 rats were randomly divided into normal group, hyperlipidemia control group, experimental group 1, 2 and 3 in which the rats were treated with ganoderma lucidum polysaccharides at dosages of 200 mg x kg(-1) and 400 mg x kg(-1) and 800 mg x kg(-1) respectively. Apart from the rats in control group, all the rats in other groups were fed with high fat forage for 30 days. The blood was collected from the tails of rats for measuring the serum TC, TG, HDL-C, LDL-C, GSH-Px, SOD and LPO. Ganoderma lucidum polysaccharides could significantly decrease the serum contents of TC, TG, LDL-c in the experimental hyperlipidemic rats (P < 0.01), and markedly increase the level of serum HDL-C (P < 0.05), Mean Level of blood LPO in the experimental groups treated by ganoderma lacidum polysaccharides at different dosages were much lower than that in hyper lipidema group, and the GSH-Px and SOD activities of blood in the group of ganoderma were much higher than those in hyperlipidema group. Ganoderma can regulate lipid metabolism, enhance the antioxidation and reduce the lipid peroxidation in the rats with hyperlipidemia.

Effect of a high-fat meal on absorption and disposition of lipophilic compounds: the importance of degree of association with triglyceride-rich lipoproteins.

PubMed

Gershkovich, Pavel; Hoffman, Amnon

2007-09-01

Following a high-fat meal, triglyceride-rich lipoproteins (TRL) are assembled in the gut and absorbed via the lymph into the blood circulation, producing a temporal hyperlipidemia. The purpose of this study is to verify the hypothesis that this transient acute postprandial hyperlipidemia affects the pharmacokinetics of lipophilic drugs on both absorption and disposition levels by the same underlying mechanism, namely the association of active lipophilic compounds with TRL in the plasma (disposition) or within the enterocyte (lymphatic transport). This concept was assessed in rats using two model compounds, DDT with high affinity to chylomicrons and diazepam which does not bind to chylomicrons. Oral administration of peanut oil significantly increased the AUC of plasma DDT concentrations following its IV bolus administration in comparison to a water treated group. On the other hand, the AUC of diazepam following IV bolus administration was the same in oil and water treated rats. While DDT is known to have significant lymphatic bioavailability, diazepam has negligible intestinal lymphatic transport (0.014+/-0.004% of a given dose). In conclusion, lipophilic molecules that bind extensively to TRL will be prone to both intestinal lymphatic transport and to post-absorptive changes in disposition (decrease in clearance and volume of distribution) following a high-fat meal.

Protective effects of Spirulina maxima on hyperlipidemia and oxidative-stress induced by lead acetate in the liver and kidney

PubMed Central

2010-01-01

Background Oxidative damage has been proposed as a possible mechanism involved in lead toxicity, specially affecting the liver and kidney. Previous studies have shown the antioxidant effect of Spirulina maxima in several experimental models of oxidative stress. The current study was carried out to evaluate the antioxidant activity of Spirulina maxima against lead acetate-induced hyperlipidemia and oxidative damage in the liver and kidney of male rats. Control animals were fed on a standard diet and did not receive lead acetate (Control group). Experimental animals were fed on a standard laboratory diet with or without Spirulina maxima 5% in the standard laboratory diet and treated with three doses of lead acetate (25 mg each/weekly, intraperitoneal injection) (lead acetate with Spirulina, and lead acetate without Spirulina groups). Results The results showed that Spirulina maxima prevented the lead acetate-induced significant changes on plasma and liver lipid levels and on the antioxidant status of the liver and kidney. On the other hand, Spirulina maxima succeeded to improve the biochemical parameters of the liver and kidney towards the normal values of the Control group. Conclusions It was concluded that Spirulina maxima has protective effects on lead acetate-induced damage, and that the effects are associated with the antioxidant effect of Spirulina. PMID:20353607

Ichnocarpus frutescens (L.) R.Br. (Apocynaceae) is used to treat diabetes and hyperlipidemia in folk medicine. The crude methanol extract and fractions of I. frutescens were investigated for antihyperlipidemic effect. Fresh leaves of I. frutescens were extracted with methanol and fractionated with hexane, benzene, ethyl acetate, acetone, and methanol. The active acetone fraction was subfractionated, which resulted in active fraction 3. The antihyperlipidemic effects of the methanol extract and fractions of I. frutescens were studied in triton WR-1339-induced and high-fat diet (HFD) obese animals. Further, lipid absorption and excretion were studied. The methanol extract significantly reduced total cholesterol (TC) by 29.63% and triglyceride (Tg) by 51.10% at 400 mg/kg in triton WR-1339-induced animals and significantly reduced TC (27.81%) and Tg (37.03%) at 400 mg/kg in HFD animals. Fraction 3 showed significant reduction in TC (25.03%) and Tg (58.05%) at 200 mg/kg. Feeding of HFD consisting 3% of fraction 3 increased feces weight and Tg level in mice. Fraction 3, showed significant decrease in plasma Tg level at the second hour, after oral administration of the lipid emulsion to rats. The observed properties apparently validate the folk medicinal use of this plant in amelioration of hyperlipidemia.

Although many artificial sweeteners (AS) have safety issues, the AS have been widely used in industry. To determine the physiologic effect of AS in the presence of hyperlipidemia, zebrafish were fed aspartame or saccharin with a high-cholesterol diet (HCD). After 12 days, 30% of zebrafish, which consumed aspartame and HCD, died with exhibiting swimming defects. The aspartame group had 65% survivability, while the control and saccharin groups had 100% survivability. Under HCD, the saccharin-fed groups had the highest increase in the serum cholesterol level (599 mg/dL). Aspartame-fed group showed a remarkable increase in serum glucose (up to 125 mg/dL), which was 58% greater than the increase in the HCD alone group. The saccharin and HCD groups had the highest cholesteryl ester transfer protein (CETP) activity (52% CE-transfer), while the HCD alone group had 42% CE-transfer. Histologic analysis revealed that the aspartame and HCD groups showed more infiltration of inflammatory cells in the brain and liver sections. Conclusively, under presence of hyperlipidemia, aspartame-fed zebrafish exhibited acute swimming defects with an increase in brain inflammation. Saccharin-fed zebrafish had an increased atherogenic serum lipid profile with elevation of CETP activity. Copyright © 2011 Elsevier Ltd. All rights reserved.

Combination therapy for treatment or prevention of atherosclerosis: Focus on the lipid-RAAS interaction☆

Large clinical trials demonstrate that control of blood pressure or hyperlipidemia reduces risk for cardiovascular events by ~30%. Factors that may further reduce remaining risk are not definitively established. One potential target is atherosclerosis, a crucial feature in the pathogenesis of cardiovascular diseases whose development is determined by multiple mechanism including complex interactions between endothelial dysfunction and insulin resistance. Reciprocal relationships between endothelial dysfunction and insulin resistance as well as cross-talk between hyperlipidemia and the rennin–angiotensin–aldosterone system may contribute to development of atherosclerosis. Therefore, one appealing strategy for prevention or treatment of atherosclerosis may be to simultaneously address several risk factors with combination therapies that target multiple pathogenic mechanisms. Combination therapy with statins, peroxisome proliferators-activated receptor agonists, and rennin–angiotensin–aldosterone system blockers demonstrate additive beneficial effects on endothelial dysfunction and insulin resistance when compared with monotherapies in patients with cardiovascular risk factors. Additive beneficial effects of combined therapy are mediated by both distinct and interrelated mechanisms, consistent with both pre-clinical and clinical investigations. Thus, combination therapy may be an important concept in developing more effective strategies to treat and prevent atherosclerosis, coronary heart disease, and co-morbid metabolic disorders characterized by endothelial dysfunction and insulin resistance.

We hypothesized that estradiol treatment would improve vascular dysfunction commonly associated with obesity, hyperlipidemia, and insulin resistance. A sham operation or 17beta-estradiol pellet implantation was performed in male lean and obese Zucker rats. Maximal vasoconstriction (VC) to phenylephrine (PE) and potassium chloride was exaggerated in control obese rats compared with lean rats, but estradiol significantly attenuated VC in the obese rats. Estradiol reduced the PE EC50 in all groups. This effect was cyclooxygenase independent, because preincubation with indomethacin reduced VC response to PE similarly in a subset of control and estrogen-treated lean rats. Endothelium-independent vasodilation (VD) to sodium nitroprusside was similar among groups, but endothelium-dependent VD to ACh was significantly impaired in obese compared with lean rats. Estradiol improved VD in lean and obese rats by decreasing EC50 but impaired function by decreasing maximal VD. The shift in EC50 corresponded to an upregulation in nitric oxide synthase III protein expression in the aorta of the estrogen-treated obese rats. In summary, estrogen treatment improves vascular function in male insulin-resistant, obese rats, partially via an upregulation of nitric oxide synthase III protein expression. These effects are counteracted by adverse factors, such as hyperlipidemia and, potentially, a release of an endothelium-derived contractile agent.

Low-density lipoprotein (LDL) is non-atherogenic, while oxidized LDL (ox-LDL) is critical to atherosclerosis. N-acetylcysteine (NAC) has anti-atherosclerotic effect with largely unknown mechanisms. The present study aimed to determine if NAC could attenuate in vivo LDL oxidation and inhibit atherosclerosis. A single dose of human native LDL was injected intravenously into male C57BL/6 mice with and without NAC treatment. Serum human ox-LDL was detected 30 min after injection, reached the peak in 3 hours, and became undetectable in 12 hours. NAC treatment significantly reduced serum ox-LDL level without detectable serum ox-LDL 6 hours after LDL injection. No difference in ox-LDL clearance was observed in NAC-treated animals. NAC treatment also significantly decreased serum ox-LDL level in patients with coronary artery diseases and hyperlipidemia without effect on LDL level. Intracellular and extracellular reactive oxidative species (ROS) production was significantly increased in the animals treated with native LDL, or ox-LDL and in hyperlipidemic LDL receptor knockout (LDLR−/−) mice that was effectively prevented with NAC treatment. NAC also significantly reduced atherosclerotic plaque formation in hyperlipidemic LDLR−/− mice. NAC attenuated in vivo oxidation of native LDL and ROS formation from ox-LDL associated with decreased atherosclerotic plaque formation in hyperlipidemia. PMID:26536834

Periodontal and cardiovascular diseases share some common underlying mechanisms. Hyperlipidemia is a major risk factor for cardiovascular diseases. This study sought to assess the association of hyperlipidemia and statin consumption with periodontal status. This cross-sectional study was conducted on 150 participants including 50 individuals with normal lipid profile (group C), 50 hyperlipidemic patients without drug therapy (group N), and 50 hyperlipidemic patients on drug therapy for a minimum of 3 months (group S). Periodontal parameters including plaque index (PI), clinical attachment level (CAL), bleeding on probing (BOP), and pocket depth (PD) were measured for all teeth except for the third molars. Serum levels of total cholesterol (TC), HDL, LDL, and triglycerides (TGs) were measured. The mean values of CAL and PD were significantly higher in the two hyperlipidemic groups compared with the C group (P < 0.005). Also, CAL and PD had significant associations with serum levels of TGs, LDL, and TC (P < 0.0001); PI in the group S was significantly lower than that in the other groups (P < 0.005). Hyperlipidemic patients showed higher values of periodontal parameters compared with the statin-treated and control groups. Lower PI in the group S may indicate the anti-inflammatory effect of statin. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

A hyperlipidemic rat model was used to examine the therapeutic effect of Sempervivum tectorum plant extract on the metabolic alterations of Al, As, B, Ba, Cd, Hg, Ni, Pb, and Ti in the liver and bile. Hyperlipidemia was produced by lipogenic diet and alcohol and verified by morphological investigation of the liver with the aid of light and an electron microscope. Element concentration in the liver and bile were determined by inductively coupled plasma optical emission spectrometry (ICP-OES). The concentration values in the liver higher than the detection limit (Al, Ba, Ni, Ti) were unambiguous. Significant differences were found for the four groups at p < 0.05 level (ANOVA). A significant difference was observed between Al and B concentration in the bile fluids of the 4 groups (p < 0.05). The excretion of Al and Ti into the bile fluid increased significantly (p < 0.05). Following the administration of S. tectorum extract to rats with hyperlipidemia, the excretion of Al, B and Ba increased, whereas the excretion of Ti decreased significantly (p < 0.05). The favorable action of the extract (protecting the liver in hyperlipidemic rats) was verified by morphological studies, and its detoxicating property was shown by the elimination of Al, Ba, Ni, and Ti from the liver.

Male albino Wistar rats were fed with atherogenic diet (4% cholesterol, 1% cholic acid, and 0.5% 2-thiouracil) daily for 30 days and treated with VA (40 mg/kg body weight) daily for a period of 30 days. Rats fed with atherogenic diet showed significant (P < 0.05) elevation in the level of plasma lipids, systolic and diastolic blood pressure, oxidative stress markers (thiobarbituric acid reactive substances, lipid peroxides) and significant (P < 0.05) reduction in the activities of enzymatic (superoxide dismutase, catalase, glutathione peroxidase) and non-enzymatic (vitamin C, vitamin E, and reduced glutathione) antioxidants in erythrocytes, plasma, and tissues (liver, kidney, and aorta). Oral administration of VA (40 mg/kg body weight) for 30 days to atherogenic diet fed rats markedly attenuates systolic, diastolic blood pressure and lipid peroxidation products. Further, VA treatment significantly improved enzymatic and non-enzymatic antioxidants levels and showed beneficial effects on lipid profile in atherogenic diet rats. All the above alterations were supported by histopathological observations. These results indicate that oral administration of VA ameliorates atherogenic diet-induced hyperlipidemia in rats by its free radical scavenging; improving the antioxidants and lipid lowering properties.

Chronic inflammation is known to be a risk for many cancers, including pancreatic cancer. Heavy alcohol drinking and cigarette smoking are major causes of pancreatitis, and epidemiological studies have shown that smoking and chronic pancreatitis are risk factors for pancreatic cancer. Meanwhile, inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2) are elevated in pancreatitis and pancreatic cancer tissues in humans and in animal models. Selective inhibitors of iNOS and COX-2 suppress pancreatic cancer development in a chemical carcinogenesis model of hamsters treated with N-nitrosobis(2-oxopropyl)amine (BOP). In addition, hyperlipidemia, obesity, and type II diabetes are also suggested to be associated with chronic inflammation in the pancreas and involved in pancreatic cancer development. We have shown that a high-fat diet increased pancreatic cancer development in BOP-treated hamsters, along with aggravation of hyperlipidemia, severe fatty infiltration, and increased expression of adipokines and inflammatory factors in the pancreas. Of note, fatty pancreas has been observed in obese and/or diabetic cases in humans. Preventive effects of anti-hyperlipidemic/anti-diabetic agents on pancreatic cancer have also been shown in humans and animals. Taking this evidence into consideration, modulation of inflammatory factors by anti-inflammatory agents will provide useful data for prevention of pancreatic cancer.

To estimate prevalence and incidence of cardiovascular (CV) risk factors of hypertension, diabetes mellitus, hyperlipidemia, and obesity in patients with rheumatoid arthritis (RA), psoriasis, or psoriatic arthritis (PsA). Patients with RA, psoriasis, or PsA were identified based on medical and pharmacy claims from the MarketScan claims databases from January 1, 2002 through December 31, 2014. Primary outcomes included age- and sex-standardized prevalence of CV risk factors during the 12 months preceding diagnosis date and incidence rates per 1,000 patient-years, with 95% confidence intervals (95% CIs) during followup. Prevalence for RA, psoriasis, and PsA cohorts for hypertension was 18.6% (95% CI 18.3-18.8), 16.6% (95% CI 16.3-17.0), and 19.9% (95% CI 19.4-20.4), respectively; for diabetes mellitus 6.2% (95% CI 6.1-6.4), 6.3% (95% CI 6.0-6.5), and 7.8% (95% CI 7.4-8.2); for hyperlipidemia 9.9% (95% CI 9.7-10.1), 10.4% (95% CI 10.2-10.7), and 11.6% (95% CI 11.2-12.0); and for obesity 4.4% (95% CI 4.2-4.6), 3.8% (95% CI 3.5-4.0), and 6.0% (95% CI 5.6-6.5). Incidence rates per 1,000 patient-years during followup for RA, psoriasis, and PsA cohorts, respectively, for hypertension were 74.0 (95% CI 72.5-75.5), 68.2 (95% CI 65.9-70.4), and 79.8 (95% CI 76.3-83.3); for diabetes mellitus 10.6 (95% CI 10.1-11.1), 13.0 (95% CI 12.1-13.8), and 14.7 (95% CI 13.5-16.0); for hyperlipidemia 40.3 (95% CI 39.4-41.3), 47.1 (95% CI 45.4-48.7), and 52.0 (95% CI 49.6-54.3); and for obesity 24.4 (95% CI 23.4-25.4), 26.4 (95% CI 25.0-27.8), and 32.9 (95% CI 30.6-35.2). Patients with RA, psoriasis, and PsA have high prevalence and incidence of CV risk factors, suggesting the need for risk factor monitoring of these patients. © 2016, American College of Rheumatology.

Background Self-reported short and/or long sleep duration have been associated with adverse cardiometabolic health outcomes in laboratory and epidemiologic studies, but interpretation of such data has been limited by methodological issues. Methods Adult respondents of the 2007-2008 US National Health and Nutrition Examination Survey (NHANES) were examined in a cross-sectional analysis (N=5,649). Self-reported sleep duration was categorized as very short (<5hrs), short (5-6hrs), normal (7-8hrs) or long (≥9hrs). Obesity, diabetes, hypertension, and hyperlipidemia were assessed by self-reported history and objectively. Statistical analyses included univariate comparisons across sleep duration categories for all variables. Binary logistic regression analyses, cardiometabolic factor as outcome and with sleep duration category as predictor, were assessed with and without covariates. Observed relationships were further assessed for dependence on race/ethnicity. Results In adjusted analyses, very short sleep was associated with self-reported hypertension (OR=2.02, 95%CI[1.45, 2.81], p<0.0001), self-reported hyperlipidemia (OR=1.96, 95%CI[1.43, 2.69], p<0.0001), objective hyperlipidemia (OR=1.41, 95%CI[1.04, 1.91], p=0.03), self-reported diabetes (OR=1.76, 95%CI[1.13, 2.74], p=0.01), and objective obesity (OR=1.53, 95%CI[1.13, 2.06], p=0.005). Regarding short sleep (5-6hrs), in adjusted analyses, elevated risk was seen for self-reported hypertension (OR=1.22, 95%CI[1.02, 1.45], p=0.03) self-reported obesity (OR=1.21, 95%CI[1.03, 1.43], p=0.02) and objective obesity (OR=1.17, 95%CI[1.00, 1.38], p<0.05). Regarding long sleep (≥9hrs), no elevated risk was found for any outcomes. Interactions with Race/Ethnicity were significant for all outcomes; race/ethnicity differences in patterns of risk varied by outcome studied. In particular, the relationship between very short sleep and obesity was strongest among Blacks/African-Americans and the relationship between short sleep and hypertension is strongest among non-Hispanic Whites, Blacks/African-Americans, and non-Mexican Hispanics/Latinos. Conclusions Short sleep duration is associated with self-reported and objectively-determined adverse cardiometabolic outcomes, even after adjustment for many covariates. Also, these patterns of risk depend on race/ethnicity. PMID:24333222

Type 2 diabetes (T2D) is the most common form of diabetes in humans and is closely associated with dyslipidemia and obesity that magnifies the mortality and morbidity related to T2D. The genetic contribution to human T2D and related metabolic disorders is evident, and mostly follows polygenic inheritance. The TALLYHO/JngJ (TH) mice are a polygenic model for T2D characterized by obesity, hyperinsulinemia, impaired glucose uptake and tolerance, hyperlipidemia, and hyperglycemia. In order to determine the genetic factors that contribute to these T2D related characteristics in TH mice, we interbred TH mice with C57BL/6J (B6) mice. The parental, F1, and F2 mice were phenotyped at 8, 12, 16, 20, and 24 weeks of age for 4-hour fasting plasma triglyceride, cholesterol, insulin, and glucose levels and body, fat pad and carcass weights. The F2 mice were genotyped genome-wide and used for quantitative trait locus (QTL) mapping. We also applied a genetical genomic approach using a subset of the F2 mice to seek candidate genes underlying the QTLs. Major QTLs were detected on chromosomes (Chrs) 1, 11, 4, and 8 for hypertriglyceridemia, 1 and 3 for hypercholesterolemia, 4 for hyperglycemia, 11 and 1 for body weight, 1 for fat pad weight, and 11 and 14 for carcass weight. Most alleles, except for Chr 3 and 14 QTLs, increased phenotypic values when contributed by the TH strain. Fourteen pairs of interacting loci were detected, none of which overlapped the major QTLs. The QTL interval linked to hypercholesterolemia and hypertriglyceridemia on distal Chr 1 contains Apoa2 gene. Sequencing analysis revealed polymorphisms of Apoa2 in TH mice, suggesting Apoa2 as the candidate gene for the hyperlipidemia QTL. Gene expression analysis added novel information and aided in selection of candidates underlying the QTLs. We identified several genetic loci that affect the quantitative variations of plasma lipid and glucose levels and obesity traits in a TH × B6 intercross. Polymorphisms in Apoa2 gene are suggested to be responsible for the Chr 1 QTL linked to hypercholesterolemia and hypertriglyceridemia. Further, genetical genomic analysis led to potential candidate genes for the QTLs.

Abstract The aim of the study is to assess the effects of celecoxib and sulfasalazine on the risk of coronary artery disease (CAD) in patients with ankylosing spondylitis (AS). Using the claims data of Taiwan National Health Insurance (NHI) database, a nationally representative data that contain the medical records of 23 million Taiwan residents, we randomly selected 1 million cohort from the database, and then we enrolled only patients who were newly diagnosed with AS (n = 4829) between year 2001 and 2010, excluding patients who had CAD (ICD-9- CM codes: 410–414) before the diagnosis of AS (n = 4112). According to propensity score matched 1:2 on age, gender, AS duration, Charlson comorbidity index, hypertension, and hyperlipidemia, 236 and 472 patients were included in the case (AS with CAD) and control (AS without CAD) groups, respectively. We used the WHO defined daily dose (DDD) as a tool to assess the dosage of sulfasalazine and celecoxib exposure. Conditional logistic regression was used to estimate the crude and adjusted odds ratios (ORs) and 95% confidence interval (CI) for the risk of CAD associated with use of sulfasalazine and celecoxib. Among 4112 AS patients, 8.4% (346/4112) developed CAD. CAD in AS patients were positively associated with age of 35 to 65, Charlson comorbidities index (CCI), hypertension, and hyperlipidemia. There was no gender difference between case and control groups. After adjustment for age, gender, CCI, hypertension, and hyperlipidemia, sulfasalazine users with an average daily dose ≥ 0.5 DDD (0.5 gm/day) had negative association with CAD events as compared to sulfasalazine nonusers (OR 0.63; 95% CI, 0.40–0.99, P < 0.05). NSAIDs, including celecoxib, etoricoxib, but no naproxen and diclofenac were negatively associated with CAD. Celecoxib users, with an average daily dose > 1.5 DDD, were negatively associated with CAD events, compared to celecoxib nonusers (OR 0.34; 95% CI, 0.13–0.89; P < 0.05). In this 10-year population-based case-control study, 8.4% of AS patients developed CAD. Sulfasalazine usage at an average dose of ≥ 0.5 gm/day demonstrated negative association with CAD events in patients with AS. PMID:27603385

DASH Eating Plan: An Eating Pattern for Diabetes Management

PubMed Central

2017-01-01

IN BRIEF The DASH (Dietary Approaches to Stop Hypertension) eating plan is an acceptable eating pattern for people who have diabetes. In addition to promoting blood pressure control, this eating pattern has been shown to improve insulin resistance, hyperlipidemia, and even overweight/obesity. This balanced approach promotes consumption of a variety of foods (whole grains, fat-free or low-fat dairy products, fruits, vegetables, poultry, fish, and nuts) and is appropriate for the entire family.

Lack of concordance between medications listed in the medical record and taken by the patient contributes to poor outcomes. We sought to determine whether patients who received health coaching by medical assistants improved their medication concordance and adherence. This was a nonblinded, randomized, controlled, pragmatic intervention trial. English- or Spanish-speaking patients, age 18 to 75 years, with poorly controlled type 2 diabetes, hypertension, and/or hyperlipidemia were enrolled from 2 urban safety net clinics and randomized to receive 12 months of health coaching versus usual care. Outcomes included concordance between medications documented in the medical record and those reported by the patient and adherence based on the patient-reported number of days (of the last 7) on which patient took all prescribed medications. The proportion of medications completely concordant increased in the coached group versus the usual care group (difference in change, 10%; P = .05). The proportion of medications listed in the chart but not taken significantly decreased in the coached group compared with the usual care group (difference in change, 17%; P = .013). The mean number of adherent days increased in the coached but not in the usual care group (difference in change, 1.08; P < .001). Health coaching by medical assistants significantly increases medication concordance and adherence. © Copyright 2015 by the American Board of Family Medicine.

To determine the prevalence of hyperlipidemia among Saudis of both genders in rural and urban communities. Selected Saudis in the age group of 30-70 years were studied over a 5-year period between 1995 and 2000 in Saudi Arabia. Data were obtained from history, physical examination, and analysis of fasting plasma lipids. The data were analyzed to classify individuals with hypercholesterolemia (HC) (total cholesterol > or =5.2 mmol/l), and hypertriglyceridemia (HT) (total triglycerides > or =1.69 mmol/l). Logistic regression analysis was performed to provide a risk assessment model and correlation with other coronary artery disease (CAD) risk factors. The number of study samples included in the final analysis was 16,819. The prevalence of HC was 54% with mean cholesterol level of 5.4+/-1.52 mmol/l. Prevalence of HC among males was 54.9% and 53.2% for females, while 53.4% among urban Saudis and 55.3% for rural Saudis. Hypertriglycemia prevalence was 40.3% with mean triglycerides level of 1.8+/-1.29 mmol/l. Males had statistically significant higher HT prevalence of 47.6% compared to 33.7% in females (p<0.0001). Hyperlipedimia is reaching higher prevalence rates in KSA. This finding may suggest that CAD will soon be a major health problem. Reduction in obesity by adopting healthier eating habits, and increasing physical activity are of considerable importance to our community.

The aim of this study was to enhance the dissolution profile of the combination of glipizide and atorvastatin used for simultaneous treatment of hyperglycemia and hyperlipidemia. The strategy to formulate coamorphous glipizide-atorvastatin binary mixture was explored to achieve enhancement in dissolution. The coamorphous glipizide-atorvastatin mixtures (1:1, 1:2 and 2:1) were prepared by cryomilling and characterized with respect to their dissolution profiles, preformulation parameters and physical stability. Amorphization was found to be possible by cryomilling at various tried ratios of the two drugs. The data obtained from glass transition temperatures and from Raman spectroscopy point toward practically no interaction between the two drugs. The dissolution studies revealed the highest enhancement in dissolution profiles of cryomilled coamorphous mixtures containing GPZ:ATV in ratios 1:1 (B-5) and 2:1 (B-7). These two mixtures were, therefore, subjected to studies for the evaluation of precompression parameters in order to find their amenability to satisfactory compression into tablet dosage form. The selected formulation was found to be stable when subjected to accelerated stability testing at 40°. C/75% RH for six months as per ICH guidelines. Based on all these studies, it was concluded that GPZ:ATV (1:1) combination may be able to provide an effective therapy for the comorbidities of hyperglycemia and hyperlipidemia.

Hyperlipidemia can lead to atherosclerosis by lipoprotein deposition inside the vessel wall and oxidative stress induction that leads to the formation of atherosclerotic plaque. Oxidized low-density lipoprotein particles (Ox-LDL) have a key role in the pathogenesis of atherosclerosis. The lipid-lowering properties and antioxidants of the grape seed can be beneficial in atherosclerosis prevention. We conducted a randomized double-blind placebo-controlled crossover clinical trial. Fifty-two mildly hyperlipidemic individuals were divided into two groups that received either 200 mg/day of the red grape seed extract (RGSE) or placebo for 8 weeks. After an 8-week washout period, the groups were crossed over for another 8 weeks. Lipid profiles and Ox-LDL were measured at the beginning and the end of each phase. RGSE consumption reduced total cholesterol (-10.68±26.76 mg/dL, P=.015), LDL cholesterol (-9.66±23.92 mg/dL, P=.014), and Ox-LDL (-5.47±12.12 mg/dL, P=.008). While triglyceride and very low-density lipoprotein cholesterol were decreased and high-density lipoprotein cholesterol was increased by RGSE, the changes were not statistically significant. RGSE consumption decreases Ox-LDL and has beneficial effects on lipid profile-consequently decreasing the risk of atherosclerosis and cardiovascular disorders-in mild hyperlipidemic individuals.

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.

Macrophages that contain abundant intracytoplasmic lipid are called 'foam cells'. In four canine globes submitted to the Comparative Ocular Pathology Laboratory of Wisconsin (COPLOW), foam cells formed a solid intraocular mass. The purpose of this study was to describe the histopathologic findings in these cases. The electronic COPLOW database (1993-2006) was searched for the diagnosis of 'foam cell tumor'. Clinical history, gross pathology and histopathology (5-micron sections, hematoxylin and eosin and Alcian blue periodic acid Schiff) were reviewed in all cases. Cases were included if the globe was grossly filled by a solid mass and if all intraocular structures were effaced by lipid-laden foam cell macrophages admixed with birefringent, Alcian blue-positive crystals oriented in stellate patterns. All three patients (four globes) satisfying the selection criteria were Miniature Schnauzers. In all cases the clinical history included diabetes mellitus, hyperlipidemia and chronic bilateral uveitis that was interpreted to be lens-induced. All globes were enucleated because of glaucoma. The term solid intraocular xanthogranuloma was used to describe these cases because the intraocular contents were effaced by a solid mass of foam cells and birefringent crystals. The cases in this report suggest that diabetic Miniature Schnauzers with hyperlipidemia are at risk for lipid and macrophage-rich uveitis, which may in some cases form a solid inflammatory intraocular mass, precipitate glaucoma, and lead to enucleation.

Anti-aggregatory effect of boswellic acid in high-fat fed rats: involvement of redox and inflammatory cascades

PubMed Central

2016-01-01

Introduction A high-fat diet is one of the main dietary factors promoting platelet aggregation. The present study was conducted to elucidate the involvement of boswellic acid (BA) on the platelet hyperaggregability in HFD-fed rats. As platelet hyperaggregability in HFD rats is closely linked to inflammation and enhanced free radical production, the present study was extended to evaluate the anti-inflammatory and anti-oxidative effect of BA on HFD-promoted platelet aggregation. Material and methods Rats were assigned to normal, HFD-fed, aspirin-treated (30 mg/kg), and BA-treated (250 and 500 mg/kg) groups. Results Boswellic acid administration in a high dose was effective in attenuating the severity of hyperlipidemia and platelet aggregation, indicated by lower collagen/epinephrine-induced platelet aggregation, as evidenced by the significant increase (p < 0.05) in the circulating platelet count and reduction in the number of thrombi in the lungs. Moreover, it attenuated the oxidative stress and the intensity of inflammatory mediators associated with platelet hyperaggregability, as evidenced by the inhibitory effects on interlukin-1β, COX-2 and tumor necrosis factor-α, indicating that the antiplatelet activity of BA is likely a consequence of controlling oxidative stress and inflammation. Conclusions The present data suggest that BA shows a promising anti-aggregatory effect by attenuating the enhanced hyperlipidemia, oxidative stress and inflammation associated with HFD.

Atherosclerosis is both a chronic inflammatory disease and a lipid metabolism disorder. C/EBPβ is well documented for its role in the development of hematopoietic cells and integration of lipid metabolism. However, C/EBPβ's role in atherosclerotic progression has not been examined. We assessed the impact of hematopoietic CEBPβ deletion in ApoE(-/-) mice on hyperlipidemia, inflammatory responses and lesion formation in the aorta. ApoE(-/-) mice were reconstituted with bone marrow cells derived from either WT or C/EBPβ(-/-) mice and placed on low fat or high fat/high cholesterol diet for 11 weeks. Hematopoietic C/EBPβ deletion in ApoE(-/-) mice reduced blood and hepatic lipids and gene expression of hepatic stearoyl CoA desaturase 1 and fatty acid synthase while expression of ATP binding cassette transporter G1, cholesterol 7-alpha-hydroxylase, and liver X receptor alpha genes were significantly increased. ApoE(-/-) mice reconstituted with C/EBPβ(-/-) bone marrow cells also significantly reduced blood cytokine levels and reduced lesion area in aortic sinuses compared with ApoE(-/-) mice reconstituted with WT bone marrow cells. Silencing of C/EBPβ in RAW264.7 macrophage cells prevented oxLDL-mediated foam cell formation and inflammatory cytokine secretion in conditioned medium. C/EBPβ in hematopoietic cells is crucial to regulate diet-induced inflammation, hyperlipidemia and atherosclerosis development. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

Alcohol is an important basic factor in health management at the workplace. The fact is, however, when alcohol is pervasive in a worker's daily life, effective measures are very difficult to carry out. We examined an intervention program based on serum y -GTP (IU/l) measurements at physical examination. Subjects were clients of the Keio Counseling Center in2005 (male, 5568: female, 1725). Among nondrinkers, gamma-GTP values were under 50 in 83% of men and 93% of women. Relative risk of lifestyle-related diseases (obesity, hypertension, hyperlipidemia, hyperuricemia, hyperglycemia and fatty liver) among male drinkers increased dramatically when gamma-GTP exceeded 50,with a further gradual increase for gamma-GTP over 100. Moreover, relative risk of over two concurrent diseases among obesity, hypertension, hyperlipidemia and hyperglycemia increased when gamma-GTP exceeded 25 and greatly increased beyond 50. While the findings suggest 25 or less as an ideal gamma-GTP values, a workplace program might more practically regard values over 50 as a threshold for management measures and values over 100 as indicating enforced management. At the workplace, management of other diseases including lifestyle-related diseases, alcoholism per se, and mental health issues needs to be carried out in a balanced, coordinated manner. Cooperation of related medical institutions and effective alcohol treatment program, and efforts to enlist the understanding and trust of all workers are needed.

The lipid profile of familial combined hyperlipidemia (FCHL) shares some characteristics with atherogenic dyslipidemia seen in diabetes, metabolic syndrome, and obesity. Adipocyte fatty acid-binding protein 4 (FABP4) appears to be a determinant of atherogenic dyslipidemia. We examined relationships between FABP4 plasma concentrations, dyslipidemia, and metabolic variables in patients with FCHL. We studied 273 unrelated FCHL patients and 118 control subjects. FABP4 was higher in FCHL than controls, with mean levels of 21.8 (10.1) μg/l and 19.2 (9.2) μg/l, respectively (adjusted P= 0.012). In FCHL, FABP4 correlated to body mass index (BMI), waist circumference, insulin levels, and homeostasis model assessment (HOMA) index (all P< 0.05), but not to lipid levels, whereas in obese patients, FABP4 correlated to triglyceride levels (r = 0.303, P= 0.014) and very low density lipoprotein size (r = 0.502, P = 0.001), as determined by nuclear magnetic resonance. Associations of FABP4 with BMI and waist circumference, but not with insulin levels, persisted in this subgroup. Plasma FABP4 does not influence the lipid phenotype of FCHL. In a small subgroup of obese FCHL, FABP4 levels were associated with triglyceride-rich lipoproteins independent of insulin resistance. These results support a hyperlipidemic mechanism of FCHL different from similar metabolic conditions where fat mass is strongly related to FABP4 and hypertriglyceridemia. PMID:20388924

This study aimed to ascertain the optimal range of red clover dry extracts (RC) and dried pomegranate concentrate powder (PCP) to induce anti-climacteric effects. Thus, the dose ranges showing protective effect of mixed formulae consisting of RC and PCP were examined in ovariectomized mice. At 28 days after bilateral ovariectomy (OVX), mixed herbal compositions (RC:PCP = 1:1, 1:2, 1:4, 1:8, 2:1, 4:1, and 8:1) were administered orally, at 120 mg/kg once daily for 84 days. We evaluated that RC and PCP mixture attenuate OVX-caused obesity, hyperlipidemia, hepatic steatosis, and osteoporosis. Compared to OVX-induced control mice, body weight and abdominal fat weight in OVX-induced mice were significantly decreased, concomitantly with increase of uterus weight by RC:PCP mixture. Additionally, significant increases in serum estradiol levels were observed in all RC:PCP-treated mice. RC:PCP mixture also showed protective effect against OVX-induced hyperlipidemia, hepatic steatosis. Total body and femur mean bone mineral density (BMD), osteocalcin, bALP contents were effectively increased by RC:PCP mixture. Taken together, RC:PCP mixture (2:1, 1:1, and 4:1) has remarkable protective effects against the changes induced by OVX. In particular, RC:PCP mixture (2:1) shows the strongest effect and may be considered as a potential protective agent against climacteric symptoms.

To assess the association between cardiovascular risk factors and extent of noncalcified- (NCAP), mixed- (MCAP), and calcified coronary atherosclerotic plaque (CAP). In this cross-sectional study, we included consecutive subjects who presented with chest pain but had no history of coronary artery disease (CAD) and did not develop acute coronary syndrome. Contrast-enhanced 64-slice coronary MDCT was performed to determine the presence of NCAP, MCAP, and CAP for each coronary segment. Among 195 patients (91 women, mean age: 54.6+/-12.0) exclusively NCAP was detected in 11 patients (5.6%). The extent of NCAP decreased and the extent of MCAP and CAP increased with age (P=0.06, P=0.02, and P=0.13, respectively). Hyperlipidemia and family history of CAD were associated with the extent of NCAP after adjusting for other risk factors (P=0.02 and P=0.04, respectively) or for the extent of MCAP and CAP (P=0.02 and P=0.05, respectively). Our data suggest that only a small proportion of individuals have exclusively NCAP and indicate that the relation of NCAP and CAP changes with age. Among individual risk factors, hyperlipidemia and family history of CAD may be associated with the extent of NCAP. Larger observational trials are necessary to confirm our findings.

Senescence-accelerated mouse prone 6 (SAMP6) is a model of senile osteoporosis. From 10 to 22 wk of age, SAMP6 mice were heavier than age-matched AKR/J and SAMR1 mice. Body mass indices of 10- and 25-wk-old SAMP6 mice were higher than those of age-matched AKR/J and SAMR1 mice, indicating obesity in the SAMP6 animals. We compared the blood biochemical values among SAMP6, SAMR1, and AKR/J mice to assess whether the SAMP6 strain has abnormal obesity-related parameters. Plasma glucose, triglyceride, insulin, and leptin levels were higher in 10-wk-old SAMP6 mice than in age-matched SAMR1 and AKR/J mice, whereas plasma glucagon and adiponectin levels in 25-wk-old SAMP6 were lower compared with those in age-matched SAMR1 and AKR/J. Total cholesterol levels in SAMR1 and SAMP6 mice at 10 and 25 wk of age were higher than those in AKR/J mice. Hepatic lipid levels were higher in 10- and 25-wk-old SAMP6 mice compared with age-matched AKR/J and SAMR1 animals. These results indicate that SAMP6 mice exhibit obesity and hyperlipidemia, suggesting that the SAMP6 strain is a potential tool for the study of hyperlipidemia. PMID:19887026

Abstract Background: Hypertension, hyperlipidemia, and diabetes are significant, but often preventable, contributors to cardiovascular disease (CVD) risk. Medication and behavioral nonadherence are significant barriers to successful hypertension, hyperlidemia, and diabetes management. Our objective was to describe the theoretical framework underlying a tailored behavioral and educational pharmacist-administered intervention for achieving CVD risk reduction. Materials and Methods: Adults with poorly controlled hypertension and/or hyperlipidemia were enrolled from three outpatient primary care clinics associated with the Durham Veterans Affairs Medical Center (Durham, NC). Participants were randomly assigned to receive a pharmacist-administered, tailored, 1-year telephone-based intervention or usual care. The goal of the study was to reduce the risk for CVD through a theory-driven intervention to increase medication adherence and improve health behaviors. Results: Enrollment began in November 2011 and is ongoing. The target sample size is 500 patients. Conclusions: The Cardiovascular Intervention Improvement Telemedicine Study (CITIES) intervention has been designed with a strong theoretical underpinning. The theoretical foundation and intervention are designed to encourage patients with multiple comorbidities and poorly controlled CVD risk factors to engage in home-based monitoring and tailored telephone-based interventions. Evidence suggests that clinical pharmacist-administered telephone-based interventions may be efficiently integrated into primary care for patients with poorly controlled CVD risk factors.

We examined the hypolipidemic effect of propolis in a mouse obesity model induced by a high fat-diet. C57BL/6N mice were fed a high-fat diet ad libitum and given propolis extract intragastrically at 0 mg/kg (control), 5 mg/kg or 50 mg/kg twice daily for 10 d. Compared with mice in the control group, mice in the propolis extract-administrated groups displayed a reduction in all of the following parameters: body weight gain, weight of visceral adipose tissue, liver and serum triglycerides, cholesterol, and non-esterified fatty acids. Real-time polymerase chain reaction analysis of the liver showed down-regulation of mRNA expression associated with fatty acid biosynthesis, including fatty acid synthase, acetyl-CoA carboxylase alpha, and sterol regulatory element binding protein in the propolis-administrated mice. Subsequently, obese C57BL/6N mice that had been administered a high-fat diet were given propolis extract at 0 mg/kg (control), 2.5 mg/kg or 25 mg/kg for 4 weeks. The propolis extract treated mice showed a decrease in weight gain, a reduction of serum non-esterified fatty acids, and lipid accumulation in the liver. These results suggest that propolis extract prevented and mitigated high-fat diet-induced hyperlipidemia by down-regulating the expression of genes associated with lipid metabolism.

Sleeve gastrectomy (LSG) is now the predominant bariatric surgery performed, yet there is limited long-term data comparing important outcomes between LSG and Roux-en-Y gastric bypass (RYGB). This study compares weight loss and impact on comorbidities of the two procedures. We retrospectively evaluated weight, blood pressure, hemoglobin A1c, cholesterol, and medication use for hypertension, diabetes, and hyperlipidemia at 1-4 years post-operatively in 380 patients who underwent RYGB and 334 patients who underwent LSG at the University of Michigan from January 2008 to November 2013. Follow-up rates from 714 patients initially were 657 (92%), 556 (78%), 507 (71%), and 498 (70%) at 1-4 years post-operatively. Baseline characteristics were similar except for higher weight and BMI in LSG. There was greater weight loss with RYGB vs. LSG at all points. Hemoglobin A1c and total cholesterol improved more in RYGB vs. LSG at 4 years. There was greater remission of hypertension and discontinuation of all medications for hypertension and diabetes with RYGB at 4 years. Weight loss, reduction in medications for hypertension and diabetes, improvements in markers of diabetes and hyperlipidemia, and remission rates of hypertension were superior with RYGB vs. LSG 4 years post-operatively. Choice of bariatric procedures should be tailored to surgical risk, comorbidities, and weight loss goals.

Obesity, generally linked to hyperlipidemia, has been occurring of late with distressing alarm and has now become a global phenomenon casting a huge economic burden on the health care system of countries around the world. The present study investigated the effects of gingerol over 30 days on the changes in HFD-induced obese rats in marker enzymes of lipid metabolism such as fatty-acid synthase (FAS), Acetyl CoA Carboxylase (ACC), Carnitine Palmitoyl Transferase-1(CPT-1), HMG co-A Reductase (HMGR), Lecithin Choline Acyl Transferase (LCAT) and Lipoprotein Lipase (LPL) and inflammatory markers (TNF-α and IL-6). The rats were treated orally with gingerol (75 mg kg(-1)) once daily for 30 days with a lorcaserin-treated group (10 mg kg(-1)) included for comparison. Changes in body weight, glucose, insulin resistance and expressions of lipid marker enzymes and inflammatory markers in tissues were observed in experimental rats. The administration of gingerol resulted in a significant reduction in body weight gain, glucose and insulin levels, and insulin resistance, which altered the activity, expressions of lipid marker enzymes and inflammatory markers. It showed that gingerol had significantly altered these parameters when compared with HFD control rats. This study confirms that gingerol prevents HFD-induced hyperlipidemia by modulating the expression of enzymes important to cholesterol metabolism. Copyright © 2015 Elsevier Ireland Ltd.

Objectives: To examine the associations between sleep duration and a variety of demographic and clinical variables in a sample of Saudi adults. Methods: A cross-sectional study among 2,095 participants was conducted at King Abdulaziz Medical City, Riyadh, Kingdom of Saudi Arabia, between May and October 2014. A questionnaire was administered to collect data related to clinical health outcomes and demographic characteristics. Participants were asked to report their average sleep duration per night in hours. Results: One-third (33.8%) reported short sleep duration of less than 7 hours/night. Short sleep duration was more prevalent in females (37.3% versus 31.4%, p=0.004). The most common medical problems reported were obesity with body mass index of >30 Kg/m2 (39.1%), hypertension (33.9%), diabetes mellitus (20.8%), depression (4.3%), asthma (17.3%), COPD (6.6%), and hyperlipidemia (2.7%). Diabetes mellitus was associated with long sleep of more than 9 hours/night (25.4%, p=0.011) and hypertension (54.2%, p=0.001). The linear regression model tend to reduce their sleep duration by roughly 22 minutes in female gender, 66 minutes in participants with hyperlipidemia, and 70 minutes in participants with poor sleep quality. Conclusions: Short sleep duration per night was prevalent, it affects one in every 3 Saudi adults. Long sleep duration of more than 9 hours was associated with increased comorbid conditions.

Morinda citrifolia, has been reported to posses different biological activities and almost all parts of this have been studied phytochemically. However there are few studies on the seeds of fruit. The objective of present study was investigated the effect to Noni Seed Oil (NSO) on serum lipid levels in normolipidemic and hyperlipidemic induced mice. We find that administration of noni oil causes a reduction in total cholesterol and triglycerides levels in both models. However hypolipidemic effect is higher when hyperlipidemia is presented.

High levels of reactive oxygen species in the body and hyperlipidemia are key factors for the development of cardiovascular diseases such as atherosclerosis. The present study investigated the antioxidant and hypolipidemic activity of hydroethanolic extract of Curatella americana L. leaves (ExC). The antioxidant activity of ExC was assessed by 2,2-diphenyl-1-picrylhydrazyl free radical (DPPH) scavenging capacity and protection against hemolysis induced by 2,2'-azobis(2-amidinopropane) dihydrochloride (AAPH), followed by quantification of malondialdehyde (MDA). Wistar rats with hyperlipidemia induced by high-fructose diet (60%) were treated for 60 days with water, simvastatin (30 mg·Kg(-1)), ciprofibrate (2 mg·Kg(-1)), and ExC (200 mg·Kg(-1)). ExC revealed IC50 of 6.0 ± 0.5 μg·mL(-1), an intermediary value among positive controls used in the assay of DPPH scavenging capacity. At all concentrations (50 to 125 μg·mL(-1)) and times (60 to 240 min) evaluated, ExC protected erythrocytes against AAPH-induced hemolysis, which was confirmed by lower MDA levels. In vivo tests showed a reduction of 34 and 45%, respectively, in serum concentration of cholesterol and triglycerides in hyperlipidemic rats treated with ExC, a similar effect compared to the reference drugs, simvastatin and ciprofibrate, respectively. Together, the results showed the antioxidant activity of ExC and its ability to improve the serum lipid profile in hyperlipidemic rats.

Prevention, Detection and Management of Coronary Artery Disease in Minority Females.

Bullock-Palmer, Renée P

2015-11-05

Heart disease is the leading cause of death for women living in the United States; this disease claims more female lives than all cancers combined. Additionally, according to the Centers of Disease Control data between the years 1979 and 2006, while cardiac-related mortality among men decreased significantly, only a modest decline was found among women. This disparity is greatest among minority females including Blacks and Hispanics who have an even greater prevalence of CVD and its risk factors. There are several risk factors for coronary artery disease (CAD). Modifiable risk factors include: tobacco smoking, hypertension, diabetes, hyperlipidemia, obesity and physical inactivity. The prevention of CAD is grounded in decreasing or removing these modifiable risk factors. Accurately diagnosing CAD is dependent on an accurate assessment of the patient's pre-test probability to determine the best diagnostic approach to pursue. The patient's functional status, resting EKG and cardiac risk factors also assist in determining the best non-invasive cardiac test to pursue. The goals and mainstay in the management of minority females with stable CAD includes surveillance for CAD symptoms, management of hypertension, diabetes mellitus and hyperlipidemia, as well as encouraging healthy habits. Heart disease remains the leading cause of death in minority females. Providers must be diligent to aggressively decrease patients' cardiovascular risk and, when patients do present with cardiovascular symptoms, providers must be aggressive in accurately diagnosing and treating these patients to decrease cardiac morbidity and mortality.

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.

Hyperlipidemia is an important factor to induce metabolic syndrome such as obesity, diabetes and cardiovascular diseases. Recently, some antihyperlipidemic agents from herbal medicines have been in the spotlight in the medical science field. Thus, the present study evaluated the antihyperlipidemic activities of the essential oil from the leaves of Pinus koraiensis SIEB (EOPK) that has been used as a folk remedy for heart disease. The reverse transcription polymerase chain reaction (RT-PCR) revealed that EOPK up-regulated low density lipoprotein receptor (LDLR) at the mRNA level as well as negatively suppressed the expression of sterol regulatory element-binding protein (SREBP)-1c, SREBP-2, 3-hydroxy-3-methyl-glutaryl-CoA reductase (HMGCR), fatty acid synthase (FAS) and glycerol-3-phosphate acyltransferase (GPAT) involved in lipid metabolism in HepG2 cells. Also, western blotting showed that EOPK activated LDLR and attenuated the expression of FAS at the protein level in the cells. Consistently, EOPK significantly inhibited the level of human acylcoenzyme A: cholesterol acyltransferase (hACAT)1 and 2 and reduced the low-density lipoprotein (LDL) oxidation activity. Furthermore, chromatography-mass spectrometry (GC-MS) analysis showed that EOPK, an essential oil mixture, contained camphene (21.11%), d-limonene (21.01%), α-pinene (16.74%) and borneol (11.52%). Overall, the findings suggest that EOPK can be a potent pharmaceutical agent for the prevention and treatment of hyperlipidemia. Copyright © 2012 John Wiley & Sons, Ltd.

Spontaneous hyperlipidemia in rats causes glomerular disease. Idiopathic hypertriglyceridemia (HTG) is prevalent in Miniature schnauzers, but its relationship with proteinuria is unknown. Decreased activity of major lipid metabolism enzymes, lipoprotein lipase (LPL) and hepatic lipase (HL), may play a role in the cyclic relationship between hyperlipidemia and proteinuria. These enzymes have also not been previously investigated in Miniature shnauzers. The aims of this study were to determine the relationship between HTG and proteinuria in Miniature schnauzers and to measure LPL and HL activities in a subset of dogs. Fifty-seven Miniature schnauzers were recruited (34 with and 23 without HTG). Fasting serum triglyceride concentrations and urine protein-to-creatinine ratios (UPC) were measured in all dogs, and LPL and HL activities were determined in 17 dogs (8 with and 9 without HTG). There was a strong positive correlation between triglyceride concentration and UPC (r = 0.77–0.83, P < 0.001). Proteinuria (UPC ≥ 0.5) was present in 60% of dogs with HTG and absent from all dogs without HTG (P < 0.001). Proteinuric dogs were not azotemic or hypoalbuminemic. Dogs with HTG had a 65% reduction in LPL activity relative to dogs without HTG (P < 0.001); HL activity did not differ. Proteinuria occurs with HTG in Miniature schnauzers and could be due to lipid-induced glomerular injury. Reduced LPL activity may contribute to the severity of HTG, but further assay validation is required. PMID:27256031

Familial combined hyperlipidemia (FCH) is a polygenic and multifactorial disease characterized by a variable phenotype showing increased levels of triglycerides and/or cholesterol. The aim of this study was to identify single nucleotides (SNPs) in lipid-related genes associated with FCH. Twenty SNPs in lipid-related genes were studied in 142 control subjects and 165 FCH patients after excluding patients with mutations in the LDLR gene and patients with the E2/E2 genotype of APOE. In particular, we studied the 9996G > A (rs2073658) and 11235C > T (rs3737787) variants in the Upstream Stimulatory Factor 1 gene (USF1), and the -1131T > C (rs662799) and S19W (rs3135506) variants in the Apolipoprotein A-V gene (APOA5). We found that the frequencies of these variants differed between patients and controls and that are associated with different lipid profiles. At multivariate logistic regression SNP S19W in APOA5 remained significantly associated with FCH independently of age, sex, BMI, cholesterol and triglycerides. Our results show that the USF1 and APOA5 polymorphisms are associated with FCH and that the S19W SNP in the APOA5 gene is associated to the disease independently of total cholesterol, triglycerides and BMI. However, more extensive studies including other SNPs such as rs2516839 in USF1, are required. Copyright © 2014 Elsevier Ltd. All rights reserved.

Refeeding syndrome in a patient with advanced kidney failure due to nephronophthisis.

Refeeding syndrome (RS) is a serious and potentially fatal disorder. It is caused by a shift of fluids, sodium, potassium, magnesium and phosphorus as well changes in the metabolism of glucose, protein, fat and vitamins following the refeeding of malnourished patients, whether enterally or parenterally. RS has rarely been reported in patients with advanced kidney disease probably due to the pre-existing hyperphosphatemia, hypermagnesemia and hyperkalemia in these patients. In the following report, we present a patient with nephronophthisis type 1 deletion syndrome in whom her main previous nutrition was limited to simply rehydration to avoid renal replacement therapy. On presentation, she was cachectic and dehydrated with advanced kidney failure. She was treated with medical nephrectomy using non-steroidal anti-inflammatory drugs and then placed on maintenance hemodialysis. Percutaneous endoscopic gastrostomy was used for her initial feeding. Care was exercised during her early refeeding with regard to correction of fluids and essential electrolytes, viz. potassium, phosphorus and magnesium, as well as multivitamins to avoid the cardiovascular and neurological complications of RS. However, the changes in the gut, pancreas and liver as well as her hyperlipidemia were a clear obstacle. Fortunately, the ileus and pancreatitis she developed on refeeding improved dramatically with a decrease of the feeding dose to half; however, the liver abnormalities and hyperlipidemia were severe and slow to recover. These improved after addition of ursodeoxycholic acid and permitted successful increase of the dose of feeding subsequently.

This study investigates the mechanism of cyclosporine A (CsA)-mediated nephrotoxicity by examining the hypothesis that CsA toxicity is mediated through its effect on the kidney drug metabolizing enzymes in a hyperlipemic rabbit model. Twenty-four female New Zealand white rabbits divided into four groups. Group 1 received regular diet. Group 2 received 1% cholesterol diet. Group 3 received CsA (25 mg/kg, orally once daily) and group 4 received 1% cholesterol diet and CsA (25 mg/kg, orally once daily). Cytochrome P450 2E1 (CYP2E1) activity in kidney microsomes was assessed by measuring p-nitrophenol hydroxylase activity. Generation of reactive oxygen species (ROS) was assessed by measuring malondialdehyde (MDA) and the protein carbonyl. Effect of CsA and hyperlipidemia on the antioxidant proteins were also assessed using standard techniques. CsA but not the high-cholesterol diet induced significant elevation in MDA, protein carbonyl and CYP2E1 activities in the kidney. The addition of cholesterol to CsA normalized ROS markers without affecting the CsA-enhanced CYP2E1 activity. Alone, CsA caused characteristic tubular injury, whereas the addition of high-cholesterol diet to CsA nearly abolished the tubular damage. CsA-enhanced rabbit kidney ROS and CYP2E1 activities. Hyperlipidemia attenuates CsA tubular injury, most probably due to normalization of renal ROS, but not CYP2E1 activity.

Vertigo, tinnitus, and hearing loss are common complaints among populations of industrial countries, especially in persons older than 40 years. Numerous agents are known to incite vertigo, tinnitus, and hearing loss, among them hyperinsulinemia, diabetes mellitus, and hyperlipidemia. In this study, we proposed to assess the occurrence of hyperinsulinemia, diabetes mellitus, and hyperlipidemia in patients suffering from vertigo, tinnitus, or hearing loss of unknown origin. Results of various tests in 48 patients were compared to those in 31 control subjects. Assessments of body mass index, blood pressure, and laryngological, audiometric, and electronystagmographic parameters were performed in all study participants. An oral glucose tolerance test was used to evaluate insulin levels, and lipoprotein phenotyping served to determine cholesterol, triglyceride, and lipoprotein levels. Patients were found to be significantly more overweight (on the basis of body mass index) than were the control subjects. Hypertension was more common among patients than controls, but the difference was significant only between the men in the two groups. Disturbances of glucose metabolism were found in 27.1% of patients but in only 9.7% of controls. Diabetes mellitus was not present in any controls but was identified in four patients. Hyperinsulinemia was almost twice as common in patients as in controls. Only the occurrence of hyperlipoproteinemia seemed not to differ between patients and control subjects. We conclude that such disturbances of glucose metabolism as diabetes mellitus and hyperinsulinemia may be responsible for inner ear diseases, whereas the role of disturbances of lipid metabolism remains vague.

Botryosphaeran, a water-soluble exopolysaccharide of the β-(1 → 3;1 → 6)-D-glucan type that has been isolated from the culture medium of Botryosphaeria rhodina MAMB-05 grown in submerged fermentation using glucose as the sole carbon source, was previously demonstrated to be non-genotoxic in peripheral blood and bone marrow, and exhibited strong anticlastogenic activity. In the present study, the effects of botryosphaeran were investigated in streptozotocin-induced diabetic rats as well as in high-fat diet-fed hyperlipidemic Wistar rats. The plasma glucose level was reduced by 52% in the diabetic group of rats after administration of 12 mg botryosphaeran/kg body weight of the rats (b.w.)/day by gavage over 15 days. A reduction in the median ration intake was accompanied by an increase in the median body weight gain, as well as the efficiency of food conversion. These results demonstrate that botryosphaeran has protective effects by reducing the symptoms of cachexia in Diabetes mellitus. Botryosphaeran administered by gavage at a concentration of 12 mg botryosphaeran/kg b.w./day over 15 days also reduced the plasma levels of total cholesterol and low density lipoprotein-cholesterol by 18% and 27%, respectively, in hyperlipidemic rats. Based on these findings, we conclude that botryosphaeran possesses hypoglycemic and hypocholesterolemic properties in conditions of diabetes mellitus and hyperlipidemia, respectively, and may be used as an oral anti-diabetic agent.

Chronic obstructive pulmonary disease (COPD) is often associated with co-morbidities. Metabolic disorders like hyperlipidemia and diabetes occur also in underweight COPD patients, although the mechanism is uncertain. Subcutaneous adipose tissue (SAT) plays an important role in energy homeostasis, since restricted capacity to increase fat cell number with increase in fat cell size occurring instead, is associated with lipotoxicity and metabolic disorders. The aim of this study is to show the protective role of SAT for the metabolic disorders in pulmonary emphysema of a murine model. We found ectopic fat accumulation and impaired glucose homeostasis with wasting of SAT in a murine model of elastase-induced pulmonary emphysema (EIE mice) reared on a high-fat diet. ONO-AE1-259, a selective E-prostanoid (EP) 2 receptor agonist, improved angiogenesis and subsequently adipogenesis, and finally improved ectopic fat accumulation and glucose homeostasis with restoration of the capacity for storage of surplus energy in SAT. These results suggest that metabolic disorders like hyperlipidemia and diabetes occured in underweight COPD is partially due to the less capacity for storage of surplus energy in SAT, though the precise mechanism is uncertained. Our data pave the way for the development of therapeutic interventions for metabolic disorders in emphysema patients, e.g., use of pro-angiogenic agents targeting the capacity for storage of surplus energy in the subcutaneous adipose tissue.

Postprandial hyperlipidemia (lipemia) is a risk factor for atherosclerosis. However, mouse models of postprandial hyperlipidemia have not been reported. Here, we report that ddY mice display marked postprandial hypertriglyceridemia in response to dietary fat. In ddY mice, the fasting serum total triacylglyceride (TG) concentration was 134 mg/dl, which increased to 571 mg/dl after an intragastric safflower oil load (0.4 ml/mouse). In C57BL/6J mice, these concentrations were 57 and 106 mg/dl, respectively. By lipoprotein analysis, ddY mice showed increases in chylomicron- and VLDL-sized TG fractions (remnants and VLDL) after fat load. In C57BL/6J mice, post-heparin plasma LPL activity after fat load was increased 4.8-fold relative to fasting. However, in ddY mice, the increase of LPL activity after fat load was very small (1.2-fold) and not significant. High fat feeding for 10 weeks led to obesity in ddY mice. A difference in LPL amino acid composition between C57BL/6J and ddY mice was detected but was deemed unlikely to cause hypertriglyceridemia because hypertriglyceridemia was not evident in other strains harboring the ddY-type LPL sequence. These findings indicate that postprandial hypertriglyceridemia in ddY mice is induced by decreased LPL activity after fat load and is associated with obesity induced by a high-fat diet.

[Incremental effect and mechanism of cyclosporine on blood concentration of statins and statin package insert information in Japan].

Cyclosporine is an indispensable immunosuppressant used in organ transplant patients, who frequently manifest hyperlipidemia. Statins, which are cholesterol-lowering agents, are often combined with cyclosporine in the treatment of hyperlipidemia of organ transplant patients. Since cyclosporine is a substrate and inhibitor of CYP3A4, researchers suspect that the immunosuppressant inhibits CYP3A4-mediated metabolism of statins, leading to an increase in statin plasma concentration and infrequently resulting in rhabdomyolysis. However, a number of clinical trials have shown cyclosporine to increase the plasma concentration of all developed statins, including those not metabolized by CYP3A4. Furthemore, recent mechanistic studies have shown organic anion transporting peptides (OATP) C to mediate the uptake of some statins and cyclosporine has been shown to inhibit the uptake via OATP-C in cultured cells. Therefore, the inhibition of hepatic uptake of statins is considered to be one of the mechanisms by which cyclosporine incrementally increases statin blood concentration. However, most current Japanese package inserts of statins give no information on change in pharmacokinetic parameters such as AUC and Cmax in the combined medication with cyclosporine. Furthermore, in the Japanese package inserts, it is either stated that cyclosporine inhibits CYP3A4-mediated metabolism or no comment is made on the mechanism. The package insert should properly provide available quantitative information on the change of pharmacokinetic parameters and the probable mechanism of action.

According to the principles of traditional Chinese medicine, medicinal and edible herbs exhibit holistic effects through their actions on multiple target organs. Four herbs, Puerariae radix, Lycium barbarum, Crataegus pinnatifida, and Polygonati rhizoma, were selected and combined to create a new herbal formula (PLCP). The protective effects of both the aqueous extract (AE) and ethanol extract (EE) of PLCP against insulin resistance (IR) and non-alcoholic fatty liver disease (NAFLD) were evaluated in both high fat and high fructose diet-fed mice. Active fractions and constituents were screened in HepG2 cells with IR or an over-accumulation of triglycerides, and were further identified by high-performance liquid chromatography/electrospray ionization/mass spectrometry. The results indicate that the AE did not improve (p > 0.05) glucose tolerance after three weeks, whereas EE showed a promising effect throughout the experiment. Medium and high doses of EE were found to reduce fasting blood glucose at week 9 by 21.1% and 24.4%, respectively. In addition, their efficacies for alleviating IR were comparable with that of metformin. Compared with AE, EE effectively improved hyperlipidemia, antioxidant status, and NAFLD. In contrast, metformin did not alleviate hyperlipidemia (p > 0.05) or NAFLD in the mice model. Results from the cell-based study indicate that the protective effects of EE were possibly due to the actions from puerarin, 3'-methoxypuerarin, daidzin, daidzein, and ononin.

Hypertriglyceridemia

Brahm, Amanda; Hegele, Robert A.

Hypertriglyceridemia (HTG) is commonly encountered in lipid and cardiology clinics. Severe HTG warrants treatment because of the associated increased risk of acute pancreatitis. However, the need to treat, and the correct treatment approach for patients with mild to moderate HTG are issues for ongoing evaluation. In the past, it was felt that triglyceride does not directly contribute to development of atherosclerotic plaques. However, this view is evolving, especially for triglyceride-related fractions and variables measured in the non-fasting state. Our understanding of the etiology, genetics and classification of HTG states is also evolving. Previously, HTG was considered to be a dominant disorder associated with variation within a single gene. The old nomenclature includes the term “familial” in the names of several hyperlipoproteinemia (HLP) phenotypes that included HTG as part of their profile, including combined hyperlipidemia (HLP type 2B), dysbetalipoproteinemia (HLP type 3), simple HTG (HLP type 4) and mixed hyperlipidemia (HLP type 5). This old thinking has given way to the idea that genetic susceptibility to HTG results from cumulative effects of multiple genetic variants acting in concert. HTG most is often a “polygenic” or “multigenic” trait. However, a few rare autosomal recessive forms of severe HTG have been defined. Treatment depends on the overall clinical context, including severity of HTG, concomitant presence of other lipid disturbances, and the patient's global risk of cardiovascular disease. Therapeutic strategies include dietary counselling, lifestyle management, control of secondary factors, use of omega-3 preparations and selective use of pharmaceutical agents. PMID:23525082

Life expectancy after pediatric renal transplantation remains lower than that of the normal population largely due to cardiovascular morbidity and mortality. Hyperlipidemia is a potentially modifiable risk factor for cardiovascular morbidity. Retrospective chart review of all available pediatric renal transplant patients (26) in a single center with assessment of anthropometry, renal function, steroid, calcineurin or mTOR inhibitor exposure and Ω3 FA supplementation. Eighteen transplant recipients without Ω3 FA supplementation served as control. Nutrition and supplement surveys were conducted with standardized questionnaires. Fasting cholesterol values were compared using the latest value prior to start of Ω3 FA and at last follow-up. Eight patients (five receiving mTOR inhibitor) started Ω3 FA supplementation at a mean dose of 29.2 ± 12 mg of EPA/kg and 16.1 ± 7.4 mg DHA/kg body weight. Median duration of treatment was 2.5 yr (range 0.8-5.9 yr) and their total fasting cholesterol at last follow-up dropped significantly from 5.08 ± 0.97 (control group 3.77 ± 0.81, p = 0.0084) to 4.17 ± 0.54 mm (p = 0.0158). High-density lipoprotein cholesterol increased not significantly from 1.74 ± 0.49 to 2.02 ± 0.93 mm. No patient had increased bleeding. Supplementation of omega-3 FAs may reduce hyperlipidaemia after pediatric renal transplantation. © 2012 John Wiley & Sons A/S.

A high-cholesterol diet stimulates alveolar bone resorption, which may be induced via tissue oxidative damage. Vitamin C reduces tissue oxidative damage by neutralizing free radicals and scavenging hydroxyl radicals, and its antioxidant effect may offer the clinical benefit of preventing alveolar bone resorption in cases of hyperlipidemia. We examined whether vitamin C could suppress alveolar bone resorption in rats fed a high-cholesterol diet. In this 12-week study, rats were divided into four groups: a control group (fed a regular diet) and three experimental groups (fed a high-cholesterol diet supplemented with 0, 1, or 2 g/l vitamin C). Vitamin C was provided by adding it to the drinking water. The bone mineral density of the alveolar bone was analyzed by microcomputerized tomography. As an index of tissue oxidative damage, the 8-hydroxydeoxyguanosine level in the periodontal tissue was determined using a competitive enzyme-linked immunosorbent assay. Hyperlipidemia, induced by a high-cholesterol diet, decreased rat alveolar bone density and increased the number of tartrate-resistant acid phosphatase-positive osteoclasts. The expression of 8-hydroxydeoxyguanosine was upregulated in the periodontal tissues. Intake of vitamin C reduced the effect of a high-cholesterol diet on alveolar bone density and osteoclast differentiation and decreased periodontal 8-hydroxydeoxyguanosine expression. In the rat model, vitamin C suppressed alveolar bone resorption, induced by high dietary cholesterol, by decreasing the oxidative damage of periodontal tissue.

Advances in stem cell therapy for the lower urinary tract.

Lower urinary tract diseases are emotionally and financially burdensome to the individual and society. Current treatments are ineffective or symptomatic. Conversely, stem cells (SCs) are regenerative and may offer long-term solutions. Among the different types of SCs, bone marrow SCs (BMSCs) and skeletal muscle-derived SCs (SkMSCs) have received the most attention in pre-clinical and clinical trial studies concerning the lower urinary tract. In particular, clinical trials with SkMSCs for stress urinary incontinence have demonstrated impressive efficacy. However, both SkMSCs and BMSCs are difficult to obtain in quantity and therefore neither is optimal for the eventual implementation of SC therapy. On the other hand, adipose tissue-derived SCs (ADSCs) can be easily and abundantly obtained from "discarded" adipose tissue. Moreover, in several head-on comparison studies, ADSCs have demonstrated equal or superior therapeutic potential compared to BMSCs. Therefore, across several different medical disciplines, including urology, ADSC research is gaining wide attention. For the regeneration of bladder tissues, possible differentiation of ADSCs into bladder smooth muscle and epithelial cells has been demonstrated. For the treatment of bladder diseases, specifically hyperlipidemia and associated overactive bladder, ADSCs have also demonstrated efficacy. For the treatment of urethral sphincter dysfunction associated with birth trauma and hormonal deficiency, ADSC therapy was also beneficial. Finally, ADSCs were able to restore erectile function in various types of erectile dysfunction (ED), including those associated with diabetes, hyperlipidemia, and nerve injuries. Thus, ADSCs have demonstrated remarkable therapeutic potentials for the lower urinary tract.

In previous study, the anti-diabetic effect of Cinnamomi Cassiae extract (Cinnamon bark: Lauraceae) in a type II diabetic animal model (C57BIKsj db/db) has been reported. To explore their mechanism of action, in present study, the effect of cinnamon extract on anti-hyperglycemia and anti-hyperlipidemia was evaluated by measuring the blood glucose levels, serum insulin, and adiponectin levels, serum and hepatic lipids, PPARalpha mRNA expression in liver and PPARgamma mRNA expression in adipose tissue, respectively. Male C57BIKs db/db mice were divided into a diabetic group and cinnamon extract treated group and examined for a period of 12 weeks (200 mg/kg, p.o). The fasting blood glucose and postprandial 2 h blood glucose levels in the cinnamon treated group were significantly lower than those in the control group (p < 0.01), whereas the serum insulin and adiponectin levels were significantly higher in the cinnamon treated group than in the control group (p < 0.05). The serum lipids and hepatic lipids were improved in the cinnamon administered group. Also the PPARalpha mRNA (liver) and PPARgamma mRNA (adipose tissue) expression levels were increased significantly in the cinnamon treated group (p < 0.05). Our results suggest that cinnamon extract significantly increases insulin sensitivity, reduces serum, and hepatic lipids, and improves hyperglycemia and hyperlipidemia possibly by regulating the PPAR-medicated glucose and lipid metabolism.

Psoriasis, a chronic inflammatory disease associated with an accelerated risk of myocardial infarction, provides an ideal human model to study inflammatory atherogenesis in vivo. We hypothesized that the increased cardiovascular risk observed in psoriasis would be partially attributable to an elevated subclinical coronary artery disease burden composed of noncalcified plaques with high-risk features. However, inadequate efforts have been made to directly measure coronary artery disease in this vulnerable population. As such, we sought to compare total coronary plaque burden and noncalcified coronary plaque burden (NCB) and high-risk plaque (HRP) prevalence between patients with psoriasis (n=105), patients with hyperlipidemia eligible for statin therapy under National Cholesterol Education Program-Adult Treatment Panel III guidelines (n=100) who were ≈10 years older, and healthy volunteers without psoriasis (n=25). Patients underwent coronary computed-tomography angiography for total coronary plaque burden and NCB quantification and HRP identification, defined as low attenuation (<30 hounsfield units), positive remodeling (>1.10), and spotty calcification. A consecutive sample of the first 50 patients with psoriasis was scanned again 1 year after therapy. Despite being younger and at lower traditional risk than patients with hyperlipidemia, patients with psoriasis had increased NCB (mean±SD: 1.18±0.33 versus 1.11±0.32, P =0.02) and similar HRP prevalence ( P =0.58). Furthermore, compared to healthy volunteers, patients with psoriasis had increased total coronary plaque burden (1.22±0.31 versus 1.04±0.22, P =0.001), NCB (1.18±0.33 versus 1.03±0.21, P =0.004), and HRP prevalence beyond traditional risk (odds ratio, 6.0; 95% confidence interval, 1.1-31.7; P =0.03). Last, among patients with psoriasis followed for 1 year, improvement in psoriasis severity was associated with improvement in total coronary plaque burden (β=0.45, 0.23-0.67; P <0.001) and NCB (β=0.53, 0.32-0.74; P <0.001) beyond traditional risk factors. Patients with psoriasis had greater NCB and increased HRP prevalence than healthy volunteers. In addition, patients with psoriasis had elevated NCB and equivalent HRP prevalence as older patients with hyperlipidemia. Last, modulation of target organ inflammation (eg, skin) was associated with an improvement in NCB at 1 year, suggesting that control of remote sites of inflammation may translate into reduced coronary artery disease risk. © 2017 American Heart Association, Inc.

Physicians must be competent in several different kinds of communication skills in order to implement shared decision making; however, these skills are not part of routine medical student education, nor are they formally taught during residency training. We developed a 1- and 2-hour workshop curriculum for internal medicine residents to promote shared decision making in treatment decisions for four common chronic conditions: diabetes, depression, hypertension, and hyperlipidemia. The workshops included a written case exercise, a short didactic presentation on shared decision-making concepts and strategies for risk communication, and two role-playing exercises focused on decision making for depression and hyperlipidemia treatment. We delivered the workshop as a required component of the resident curriculum in ambulatory medicine. To evaluate the impact of the workshop, we used written course evaluations, tracked the use of the newly introduced Decision Worksheets, and asked preceptors to perform direct observation of treatment decision conversations. Residents were involved in the development of the workshop and helped identify key content, suggested framing for difficult topics, and confirmed the need for the skills workshop. One hundred thirty internal medicine and medicine-pediatrics residents attended 8 workshops over a 4-month period. In written cases completed before the workshop, the majority of residents indicated that they would discuss medications, but few mentioned other treatment options or documented patients' goals and preferences in a sample encounter note with a patient with new depression symptoms. Overall, most participants (89.7%) rated the workshop as excellent or very good, and 93.5% said that they would change their practice based on what they learned. Decision Worksheets addressing diabetes, depression, hyperlipidemia, and hypertension were available on a primary care-focused intranet site and were downloaded almost 1,200 times in the first 8 months following the workshops. Preceptors were able to observe only one consult during which one of the four topics was discussed. Internal medicine residents had considerable gaps in shared decision-making skills as measured in a baseline written exercise. Residents provided valuable contributions to the development of a Decision Worksheet to be used at the point of care. Participants rated the skills workshop highly, though interns rated the exercise more useful than PGY-2 and PGY-3 residents did. The Decision Worksheets were accessed often following the sessions; however, observing the Decision Worksheets in use in real time was a challenge in the resident-faculty clinic. Additional studies are warranted to examine whether the workshop was successful in increasing residents' ability to implement skills in practice.

The authors report a case of severe hypertriglyceridemia (148.5 mmol/l) in a 27-year-old woman admitted for coma of unknown origin. Initial investigations revealed ketoacidosis, pancreatitis and noncardiogenic pulmonary edema. The diabetes was unknown. Ketoacidosis was rapidly controlled. The hypertriglyceridemia was corrected by one course of plasma exchange (4,400 ml) during which the patient returned to consciousness. The patient recovered without any sequelae. Only 2 similar cases, treated by plasma exchange, have been reported in the literature until now.

A healthy diet plays a key role in the prevention and management of cardiovascular diseases. Dark chocolate in particular has been shown to improve endothelial functions and lipid profile and to have cardiovascular protective effects via an inhibitory action on platelet functions. Recently, several studies have demonstrated the beneficial effects of chocolate, primarily on hypertension and other conditions such as coronary artery disease and hyperlipidemia. The present review provides a summary of the ingredients, bioavailability and cardiovascular protective effects of chocolate / cocoa and the published effects of chocolate on a number of cardiovascular diseases.

Regular exercise is an effective nonpharmacologic therapy for stress, sleep disorders, depression, and anxiety, as well as such chronic conditions of aging as hypertension, obesity, diabetes mellitus, coronary artery disease, hyperlipidemia, and constipation. Pre-exercise office assessment of cardiac risk, possible limitations, and contraindications is advised. A balanced fitness training program includes activities to increase flexibility, strength, and cardiovascular endurance. The most effective exercise prescription begins with a type of aerobic activity the patient enjoys. A prescribed schedule of stepwise increments in frequency, duration, and intensity gradually leads to a maintenance level of fitness.

A 7-month intervention was undertaken to determine the impact of education and coaching on lifestyle choices and lipid values among employees with hyperlipidemia. Four classes over 2 months at the worksite during work time and two telephone interventions were provided with pre, mid, and post data collection. Total cholesterol and low-density lipoprotein values improved during the intervention. Positive lifestyle changes were made involving exercise and diet. Appropriate physician visits and continuous health care increased. Lipid-based interventions at the worksite can elicit positive changes in lifestyle, appropriate health care use, and improved lipid values.

Mimosa pudica Lin., known as chue Mue, is a stout straggling prostrate shrubby plant, with spinous stipules and globose pinkish flower heads, and grows as weed in almost all parts of the country. It is traditionally used for its various properties and hence in the present study, chloroform extract of Mimosa pudica leaves has been screened for its hypolipidemic activity. Hypolipidemic activity is screened by inducing hyperlipidemia with the help of atherogenic diet in wistar albino rats and serum levels of various biochemical parameters such as total cholesterol, triglycerides, LDL, VLDL and HDL cholesterol were determined. Atherogenic index shows the measure of the athero-genic potential of the drugs. Chloroform extract showed significant (p < 0.05) hypolipidemic effect by lowering the serum levels of biochemical parameters such as significant reduction in the level of serum cholesterol, triglyceride, LDL, VLDL and increase in HDL level which was similar to the standard drug Atorvastatin. Chloroform extract exhibited significant atherogenic index and percentage protection against hyperlipidemia. These biochemical observations were in turn confirmed by histopathological examinations of aorta, liver and kidney sections and are comparable with the standard hypolipidemic drug Atorvastatin. Preliminary phytochemical analysis revealed the presence of phytoconstituents such as steroids, flavonoids, glycosides, alkaloids, phenolic compounds which is further confirmed by the thin layer chromatography, High Performance Thin Layer Chromatography (HPTLC). The overall experimental results suggests that the biologically active phytoconstituents such as flavonoids, glycosides alkaloids present in the chloroform extract of Mimosa pudica, may be responsible for the significant hypolipidemic activity and the results justify the use of Mimosa pudica as a significant hypolipidemic agent.

The objectives of this observational study were to determine the prevalence of the most common comorbidities in women and men with epilepsy and to demonstrate the relationship of these comorbidities to health plan paid costs. Data for 6621 members with epilepsy (52% women, 48% men) from eight commercial health plans were analyzed. The presence of comorbidities in people with epilepsy was identified by searching health insurance claims for 29 prespecified comorbidity-specific diagnosis codes. More women (50%) than men (43%) with epilepsy had one or more of the 29 comorbidities (p<0.05). The top 10 comorbidities for women and their relative prevalences were psychiatric diagnosis (16%), hypertension (12%), asthma (11%), hyperlipidemia (11%), headache (7%), diabetes (6%), urinary tract infection (5%), hypothyroidism (5%), anemia (5%), and migraine (4%). For men, the top 10 comorbidities and their relative prevalences were psychiatric diagnosis (15%), hyperlipidemia (12%), hypertension (12%), asthma (8%), diabetes (5%), headache (4%), cancer (4%), coronary artery disease (3%), anemia (3%), and gastroesophageal reflux disease (3%). Seven of the top 10 comorbidities were common to both women and men. Psychiatric diagnosis was the only comorbidity among the top five comorbidities for all age groups. The presence of one comorbidity approximately tripled the health-care cost for that member compared with the cost for members who had no comorbidities. Additional comorbidities generally further increased costs. The increase in health-care cost per member per month ($) with increase in number of comorbidities was greater for men than for women (p<0.05). Copyright © 2014 Elsevier Inc. All rights reserved.

HIV-infected individuals have an increased risk of avascular bone necrosis (AVN). Antiretroviral therapy (ART) and particularly protease inhibitors (PI) have been implicated as a risk factor. We aimed to study the associations of ART with the occurrence of AVN among Swiss HIV Cohort Study participants (SHCS). We used incidence density sampling to perform a case control study within the Swiss HIV Cohort Study (SHCS) comparing prospectively collected AVN cases and controls by conditional logistic regression analysis. To evaluate the effect of ART, multivariable models were adjusted for HIV transmission risk group, age, alcohol consumption, use of corticosteroids, CD4 nadir, maximum viral load, and pancreatitis. We compared 74 AVN cases and 145 controls. Associations with AVN were shown for heterosexual HIV acquisition (odds ratio [OR], 3.4; 95% confidence interval [CI], 1.1-10), alcohol consumption (OR, 2.7; 95% CI, 1.3-5.7), and hyperlipidemia (OR, 3.6; 95% CI, 1.4-9.6). After adding ART substances to the multivariable base model, there was evidence of an association for treatment with tenofovir (TDF) >1 year (OR, 4.4; 95% CI, 1.4-14) with AVN. Neither exposure to specific frequently prescribed ART combinations or ART drug classes nor cumulative ART exposure showed any associations with AVN. In the HIV-infected population, a combination of risk factors such as heterosexual HIV acquisition, moderate to severe alcohol intake, and hyperlipidemia seem to contribute to AVN. ART does not seem to be a relevant risk factor for AVN. The association of prolonged TDF exposure with AVN needs to be confirmed.

Patients' beliefs about the cause of cardiac disease (perceived risk factors) as part of the global psychological presentation are influenced by patients' health knowledge. Hence, the present study aimed to assess the relationship between actual and perceived risk factors, identification of underestimated risk factors, and indication of underestimation of every risk factor. In this cross-sectional study, data of 313 coronary artery bypass graft (CABG) patients admitted to one hospital in the west of Iran were collected through a demographic interview, actual risk factors' checklist, open single item of perceived risk factors, and a life stressful events scale. Data were analyzed by means of Spearman's correlation coefficients and one-sample Z-test for proportions. Although there are significant relations between actual and perceived risk factors related to hypertension, family history, diabetes, smoking, and substance abuse (P < 0.05), there is no relation between the actual and perceived risk factors, and patients underestimate the role of actual risk factors in disease (P < 0.001). The patients underestimated the role of aging (98.8%), substance abuse (95.2%), overweight and obesity (94.9%), hyperlipidemia (93.1%), family history (90.3%), and hypertension (90%) more than diabetes (86.1%), smoking (72.5%), and stress (54.7%). Cardiac patients seem to underestimate the role of aging, substance abuse, obesity and overweight, hyperlipidemia, family history, and hypertension more than other actual risk factors. Therefore, these factors should be highlighted to patients to help them to (i) increase the awareness of actual risk factors and (ii) promote an appropriate lifestyle after CABG surgery.

Concurrent peer review visits are structured office visits conducted by clinician peers of the primary care clinician that are specifically designed to reduce competing demands, clinical inertia, and bias. We assessed whether a single concurrent peer review visit reduced clinical inertia and improved control of hypertension, hyperlipidemia, and diabetes control among underserved patients. We conducted a randomized encouragement trial to evaluate concurrent peer review visits with a community health center. Seven hundred twenty-seven patients with hypertension, hyperlipidemia, and/or diabetes who were not at goal for systolic blood pressure (SBP), low-density lipoprotein cholesterol (LDL-C), and/or glycated hemoglobin (A1c) were randomly assigned to an invitation to participate in a concurrent peer review visit or to usual care. We compared change in these measures using mixed models and rates of therapeutic intensification during concurrent peer review visits with control visits. One hundred seventy-one patients completed a concurrent peer review visit. SBP improved significantly (p < .01) more among those completing concurrent peer review visits than among those who failed to respond to a concurrent peer review invitation or those randomized to usual care. There were no differences seen for changes in LDL-C or A1c. Concurrent peer review visits were associated with statistically significant greater clinician intensification of blood pressure (p < .001), lipid (p < .001), and diabetes (p < .005) treatment than either for control visits for patients in either the nonresponse group or usual care group. Concurrent peer review visits represent a promising strategy for improving blood pressure control and improving therapeutic intensification in community health centers.

Elastin is a major arterial structural protein, and elastin-derived peptides are related to arterial change. We previously reported on a novel assay developed using aortic elastin peptides; however, its clinical implications remain unclear. In this study, we assessed whether anti-elastin antibody titers reflect the risk of coronary artery disease (CAD) or its characteristics. We included 174 CAD patients and 171 age- and sex-matched controls. Anti-elastin antibody titers were quantified by enzyme-linked immunosorbent assay. Parameters of arterial stiffness, including the augmentation index (AI) and heart-to-femoral pulse wave velocity (hfPWV), were measured non-invasively. The clinical and angiographic characteristics of CAD patients were also evaluated. Associations between anti-elastin levels and vascular characteristics were examined by linear regression analysis. The median blood level of anti-elastin was significantly lower in the CAD group than in the controls [197 arbitrary unit (a.u.) vs. 63 a.u., p<0.001]. Levels of anti-elastin were significantly lower in men and in subjects with hypertension, diabetes mellitus, hyperlipidemia, or high hfPWV. Nevertheless, anti-elastin levels were not dependent on atherothrombotic events or the angiographic severity of CAD. In a multivariate analysis, male sex (β=-0.38, p<0.001), diabetes mellitus (β=-0.62, p<0.001), hyperlipidemia (β=-0.29, p<0.001), and AI (β=-0.006, p=0.02) were ultimately identified as determinants of anti-elastin levels. Lower levels of anti-elastin are related to CAD. The association between antibody titers and CAD is linked to arterial stiffness rather than the advancement of atherosclerosis.

The impact of a pharmacist-physician collaborative care model on patient outcomes and health services utilization is described. Six hospitals from the Carilion Clinic health system in southwest Virginia, along with 22 patient-centered medical home (PCMH) practices affiliated with Carilion Clinic, participated in this project. Eligibility criteria included documented diagnosis of 2 or more of the 7 targeted chronic conditions (congestive heart failure, hypertension, hyperlipidemia, diabetes mellitus, asthma, chronic obstructive pulmonary disease, and depression), prescriptions for 4 or more medications, and having a primary care physician in the Carilion Clinic health system. A total of 2,480 evaluable patients were included in both the collaborative care group and the usual care group. The primary clinical outcomes measured were the absolute change in values associated with diabetes mellitus, hypertension, and hyperlipidemia management from baseline within and between the collaborative care and usual care groups. Significant improvements ( p < 0.01) in glycosylated hemoglobin, blood pressure, low-density-lipoprotein cholesterol, and total cholesterol were observed in the collaborative care group compared with the usual care group. Hospitalizations declined significantly in the collaborative care group (23.4%), yielding an estimated cost savings of $2,619 per patient. The return on investment (net savings divided by program cost) was 504%. Inclusion of clinical pharmacists in this physician-pharmacist collaborative care-based PCMH model was associated with significant improvements in patients' medication-related clinical health outcomes and a reduction in hospitalizations.

The present study aimed to investigate the prevalence of central obesity among adults with normal BMI and its association with metabolic diseases in Jilin Province, China. A population-based cross-sectional study was conducted in 2012 in Jilin Province of China. Information was collected by face to face interview. Descriptive data analysis and 95% confidence intervals (CI) of prevalence/frequency were conducted. Log-binomial regression analyses were used to find the independent factors associated with central obesity and to explore the adjusted association between central obesity and metabolic diseases among adults with normal BMI. Among the adult residents with normal BMI in Jilin Province, 55.6% of participants with central obesity self-assessed as normal weight and 27.0% thought their body weight were above normal. 12.7% of central obesity people took methods to lose weight, while 85.3% didn't. Female, older people and non-manual worker had higher risk to be central obesity among adults with normal BMI. Hypertension, diabetes and hyperlipidemia were significantly associated with central obesity among adults with normal BMI, the PRs were 1.337 (1.224-1.461), 1.323 (1.193-1.456) and 1.261 (1.152-1.381) separately when adjusted for gender, age and BMI. Hypertension, diabetes and hyperlipidemia were significantly associated with central obesity among adults with normal BMI in Jilin Province, China. The low rates of awareness and control of central obesity among adults with normal BMI should be improved by government and health department.

In this study, we examined the effects of apple polyphenols (APs) on hyperlipidemia, atherosclerosis, hepatic steatosis and endothelial function and investigated the potential mechanisms. ApoE(-/-) mice were fed a western-type diet and orally treated with APs (100 mg/kg) or atorvastatin (10 mg/kg) for 12 weeks. Hyperlipidemia and atherosclerosis in the aortic sinuses and, and hepatic lipidosis were measured. The treatment with APs or atorvastatin induced a remarkable reduction in the atherosclerotic lesions and hepatic steatosis and decreased the levels of low-density lipoprotein, triglyceride, CCL-2 and VCAM-1 levels in the plasma. Conversely, the APs significantly increased the plasma levels of high-density lipoprotein (HDL) cholesterol and markedly up-regulated the glutathione peroxidase (GPx), catalase (CAT) and superoxide dismutase (SOD) levels in liver tissues. Moreover, the APs treatment modulated lipid metabolism by up-regulating the transcription of associated hepatic genes including PPARα, while down-regulating the transcription of SCAP and its downstream genes associated with lipid synthesis in the liver. Histological assessment showed that the APs treatment also reduced the macrophage infiltration in the aortic root plaque and the inflammatory cells infiltrations to the liver tissues. Moreover, we confirmed that the APs treatment greatly reduced the ox-LDL-induced endothelial dysfunction and monocyte adhesion to rat aortic endothelial cells (RAECs). Mechanistically, the APs treatment suppressed the ROS/MAPK/NF-κB signaling pathway, and consequently, reduced CCL-2, ICAM-1 and VCAM-1 expression. Our results suggest that the APs are a beneficial nutritional supplement for the attenuation of atherosclerosis.

The aim of this study is to evaluate the relationship between abdominal subcutaneous fat thickness measured by ultrasonography (US) and serum lipid profile and liver transaminases in obese children. One hundred and sixty-six children diagnosed with obesity from May 2001 to December 2013 were included in this study. Data on serum lipid profile and liver transaminases were collected from clinical records. Abdominal subcutaneous fat thickness and grade of hepatic steatosis were evaluated by US. Of the 166 children, 107 were diagnosed with hepatic steatosis by US, 46 with grade I, 56 with grade II, and five children with grade III. According to the grade of hepatic steasosis, the average values of midline abdominal subcutaneous fat thickness and right flank abdominal subcutaneous fat thickness measured 2.9±0.8 cm and 1.9±0.7 cm in the normal group, 3.3±0.8 cm and 2.0±0.7 cm in grade I, 3.8±0.8 cm and 2.3±0.8 cm in grade II, and 4.1±0.8 cm and 2.8±1.4 cm in grade III, respectively. Abdominal subcutaneous fat thickness correlated with grade of hepatic steatosis (p<0.01). In addition, abdominal subcutaneous fat thickness correlated with concentration of serum lipids and liver transaminases in the age group of 12-14 years (p<0.01). Abdominal subcutaneous fat thickness measured by US can be used as a reliable predictor of possible hyperlipidemia and steatohepatitis in children, especially during the adolescent stage.

Our aim was to assess the possible impact of a deterioration of renal function (DRF) not fulfilling the criteria for acute kidney injury after percutaneous coronary intervention (PCI) on outcome in patients with ST-elevation myocardial infarction (STEMI) on 30-day and long-term outcomes. Data is lacking on the influence of DRF after PCI on outcome in patients with STEMI. The present study is an analysis of 2572 STEMI patients who underwent PCI. The group with DRF (1022 patients) and the group without DRF (1550 patients) were compared. Thirty-day and long-term all-cause mortality were observed. Data was analyzed using descriptive statistics. Similar mortality was observed in both groups at day 30 (4.2% patients with DRF died vs 3.2% without DRF; ns) but more patients had died in the DRF group (18.9% patients with DRF vs 14.0% without DRF; P = 0.001) by the end of the observation period. After adjustments, DRF did not independently predict long-term mortality. Age more than 70 years, bleeding, hyperlipidemia, renal dysfunction on admission, anemia on admission, diabetes, PCI of LAD, the use of more than 200 mL contrast, but not DRF after PCI, were identified as independent prognostic factors for increased long-term mortality. Renal dysfunction, bleeding, contrast >200 mL, hyperlipidemia, age >70 years, anemia, and PCI LAD predicted DRF. DRF identified patients at increased risk of higher long-term mortality but was not independently associated with mortality. © 2017, Wiley Periodicals, Inc.

Background We compared cardiovascular (CV) risk factors (CVRFs) of community-based participatory research (CBPR) participants with the community population to better understand how CBPR participants relate to the population as a whole. Methods GoodNEWS participants in 20 African-American churches in Dallas, Texas were compared with age/sex-matched African-Americans in the Dallas Heart Study (DHS), a probability-based sample of Dallas County residents. DHS characteristics were sample-weight adjusted to represent the Dallas County population. Results Despite having more education (college education: 75 versus 51%, P< 0.0001), GoodNEWS participants were more obese (mean body mass index: 34 versus 31 kg/m2, P< 0.001) and had more diabetes (23 versus 12%, P< 0.001) and hyperlipidemia (53 versus 14%, P< 0.001) compared with African-Americans in Dallas County. GoodNEWS participants had higher rates of treatment and control of most CVRFs (treated hyperlipidemia: 95 versus 64%, P< 0.001; controlled diabetes: 95 versus 21%, P< 0.001; controlled hypertension: 70 versus 52%, P= 0.003), were more physically active (233 versus 177 metabolic equivalent units-min/week, P< 0.0001) and less likely to smoke (10 versus 30%, P< 0.001). Conclusions Compared with African-Americans in Dallas County, CBPR participants in church congregations were more educated, physically active and had more treatment and control of most CVRFs. Surprisingly, this motivated population had a greater obesity burden, identifying them as a prime target for CBPR-focused obesity treatment. PMID:22811446

Paleolithic nutrition improves plasma lipid concentrations of hypercholesterolemic adults to a greater extent than traditional heart-healthy dietary recommendations.

Pastore, Robert L; Brooks, Judith T; Carbone, John W

Recent research suggests that traditional grain-based heart-healthy diet recommendations, which replace dietary saturated fat with carbohydrate and reduce total fat intake, may result in unfavorable plasma lipid ratios, with reduced high-density lipoprotein (HDL) and an elevation of low-density lipoprotein (LDL) and triacylglycerols (TG). The current study tested the hypothesis that a grain-free Paleolithic diet would induce weight loss and improve plasma total cholesterol, HDL, LDL, and TG concentrations in nondiabetic adults with hyperlipidemia to a greater extent than a grain-based heart-healthy diet, based on the recommendations of the American Heart Association. Twenty volunteers (10 male and 10 female) aged 40 to 62 years were selected based on diagnosis of hypercholesterolemia. Volunteers were not taking any cholesterol-lowering medications and adhered to a traditional heart-healthy diet for 4 months, followed by a Paleolithic diet for 4 months. Regression analysis was used to determine whether change in body weight contributed to observed changes in plasma lipid concentrations. Differences in dietary intakes and plasma lipid measures were assessed using repeated-measures analysis of variance. Four months of Paleolithic nutrition significantly lowered (P < .001) mean total cholesterol, LDL, and TG and increased (P < .001) HDL, independent of changes in body weight, relative to both baseline and the traditional heart-healthy diet. Paleolithic nutrition offers promising potential for nutritional management of hyperlipidemia in adults whose lipid profiles have not improved after following more traditional heart-healthy dietary recommendations.

Serum Lipoproteins Are Critical for Pulmonary Innate Defense against Staphylococcus aureus Quorum Sensing.

Hyperlipidemia has been extensively studied in the context of atherosclerosis, whereas the potential health consequences of the opposite extreme, hypolipidemia, remain largely uninvestigated. Circulating lipoproteins are essential carriers of insoluble lipid molecules and are increasingly recognized as innate immune effectors. Importantly, severe hypolipidemia, which may occur with trauma or critical illness, is clinically associated with bacterial pneumonia. To test the hypothesis that circulating lipoproteins are essential for optimal host innate defense in the lung, we used lipoprotein-deficient mice and a mouse model of Staphylococcus aureus pneumonia in which invasive infection requires virulence factor expression controlled by the accessory gene regulator (agr) operon. Activation of agr and subsequent virulence factor expression is inhibited by apolipoprotein B, the structural protein of low-density lipoprotein, which binds and sequesters the secreted agr-signaling peptide (AIP). In this article, we report that lipoprotein deficiency impairs early pulmonary innate defense against S. aureus quorum-sensing-dependent pathogenesis. Specifically, apolipoprotein B levels in the lung early postinfection are significantly reduced with lipoprotein deficiency, coinciding with impaired host control of S. aureus agr-signaling and increased agr-dependent morbidity (weight loss) and inflammation. Given that lipoproteins also inhibit LTA- and LPS-mediated inflammation, these results suggest that hypolipidemia may broadly impact posttrauma pneumonia susceptibility to both Gram-positive and -negative pathogens. Together with previous reports demonstrating that hyperlipidemia also impairs lung innate defense, these results suggest that maintenance of normal serum lipoprotein levels is necessary for optimal host innate defense in the lung.

Preclinical Research Rhizoma Coptidis (RC), the root of Coptis chinensis Franch, a species in the genus Coptis (family Ranunculaceae), has been commonly prescribed for the treatment of diabetes in Chinese traditional herbal medicine applications. The present study is focused on the assessment of the antihyperglycemia and antidiabetic hyperlipidemia effect of five protoberberine alkaloids, berberine (BBR), coptisine (COP), palmatine (PAL), epiberberine (EPI), and jatrorrhizine (JAT), separated from R. Coptidis in hepatocellular carcinoma HepG2 cells and diabetic KK-Ay mice. Protoberberine alkaloids are effective in modulating hyperglycemia and hyperlipidemia. After adding BBR and COP to culture medium, glucose consumption of HepG2 cells was increased. In KK-Ay mice assays, suppressed fasting blood glucose level and ameliorated glucose tolerance were observed after BBR/COP administration. After treated with berberine and coptisine, in the same dose of 5 µg/mL, the glucose consumption of HepG2 cells were promoted and, respectively, reached 96.1% and 17.6%. Body weight, food consumption, water intake, and urinary output of KK-Ay mice were reduced after treated with EPI. Serum total cholesterol and triglyceride of mice were decreased after treated with palmatine and jatrorrhizine. Serum high-density lipoprotein cholesterol of mice was increased after palmatine, jatrorrhizine, and berberine administrated. Moreover, hepatomegaly was attenuated in JTR-treated mice. Suggested that these protoberberine alkaloids from R. Coptidis have potential curative effect for diabetes.

Perturbations in hepatic lipid and very-low-density lipoprotein (VLDL) metabolism are involved in the pathogenesis of obesity and hepatic insulin resistance. The objective of this study is to delineate the mechanism of subdiaphragmatic vagotomy in preventing obesity, hyperlipidemia, and insulin resistance. By subjecting the complete subdiaphragmatic vagotomized mice to various nutritional conditions and investigating hepatic de novo lipogenesis pathway, we found that complete disruption of subdiaphragmatic vagal signaling resulted in a significant decrease of circulating VLDL-triglyceride compared with the mice obtained sham procedure. Vagotomy further prevented overproduction of VLDL-triglyceride induced by an acute fat load and a high-fat diet-induced obesity, hyperlipidemia, hepatic steatosis, and glucose intolerance. Mechanistic studies revealed that plasma glucagon-like peptide-1 was significantly raised in the vagotomized mice, which was associated with significant reductions in mRNA and protein expression of SREBP-1c (sterol regulatory element-binding protein 1c), SCD-1 (stearoyl-CoA desaturase-1), and FASN (fatty acid synthase), as well as enhanced hepatic insulin sensitivity. In vitro, treating mouse primary hepatocytes with a glucagon-like peptide-1 receptor agonist, exendin-4, for 48 hours inhibited free fatty acid, palmitic acid treatment induced de novo lipid synthesis, and VLDL secretion from hepatocytes. Elevation of glucagon-like peptide-1 in vagotomized mice may prevent VLDL overproduction and insulin resistance induced by high-fat diet. These novel findings, for the first time, delineate an intrinsic gut-liver regulatory circuit that is mediated by glucagon-like peptide-1 in regulating hepatic energy metabolism. © 2017 American Heart Association, Inc.

The toll-like receptor 4 (TLR4)-myeloid differentiation factor 88 (MyD88)-dependent signaling pathway plays a role in the initiation and progression of coronary artery disease (CAD). We investigated SNP-SNP interactions between the TLR4 and MyD88 genes in CAD susceptibility and assessed whether the effects of such interactions were modified by confounding risk factors (hyperglycemia, hyperlipidemia and Helicobacter pylori (H. pylori) infection). Participants with CAD (n = 424) and controls (n = 424) without CAD were enrolled. Polymerase chain restriction-restriction fragment length polymorphism was performed on genomic DNA to detect polymorphisms in TLR4 (rs10116253, rs10983755, and rs11536889) and MyD88 (rs7744). H. pylori infections were evaluated by enzyme-linked immunosorbent assays, and the cardiovascular risk factors for each subject were evaluated clinically. The significant interaction between TLR4 rs11536889 and MyD88 rs7744 was associated with an increased CAD risk (p value for interaction = 0.024). In conditions of hyperglycemia, the interaction effect was strengthened between TLR4 rs11536889 and MyD88 rs7744 (p value for interaction = 0.004). In hyperlipidemic participants, the interaction strength was also enhanced for TLR4 rs11536889 and MyD88 rs7744 (p value for interaction = 0.006). Thus, the novel interaction between TLR4 rs11536889 and MyD88 rs7744 was related with an increased risk of CAD, that could be strengthened by the presence of hyperglycemia or hyperlipidemia.

Linum usitatissimum L. (Linaceae), commonly known as flaxseed, is a good source of dietary fiber and lignans. Earlier we reported cardioprotective, antihyperlipidemic, and in vitro antioxidant activity of flax lignan concentrate (FLC) obtained from flaxseed. To isolate secoisolariciresinol diglucoside (SDG) from FLC and to evaluate the antihyperlipidemic activity of SDG in poloxamer-407 (P-407)-induced hyperlipidaemic mice. FLC was subjected to column chromatography and further subjected to preparative HPTLC to isolate SDG. The chemical structure of the isolated compound was elucidated by UV, IR, (1)H NMR, (13)C NMR, DEPT, COSY, HSQC, HMBC, ROESY, MS, and specific optical rotation was recorded. Further, we have investigated the antihyperlipidaemic effect of SDG (20 mg/kg) in P-407-induced hyperlipidaemic rats. Hyperlipidaemia was induced by intraperitoneal administration of P-407 (30% w/v). Serum lipid parameters such as total cholesterol (TC), triglycerides (TG), and high-density lipoprotein cholesterol (HDL-C) levels were measured. The structure and stereochemistry of the isolated compound were confirmed on the basis of 1D and 2D spectral data and characterized as SDG. Finally, isolated pure SDG was screened using a P-407-induced mice model for its antihyperlipidemic action using serum lipid parameters. The isolated SDG (20 mg/kg) significantly reduced serum cholesterol, triglyceride (p < 0.001), very low-density lipoprotein (p < 0.05), and non-significantly increased HDL-C. Finally, it was concluded unequivocally that SDG showed antihyperlipidaemic effects in P-407-induced hyperlipidaemic mice. Isolated pure SDG confirms that SDG is beneficial in the prevention of experimental hyperlipidemia in laboratory animals.

Abstract Obesity is causally linked to a number of comorbidities, including cardiovascular disease, diabetes, renal dysfunction, and cancer. Obesity has also been linked to pulmonary disorders, including pulmonary arterial hypertension (PAH). It was long believed that obesity-related PAH was the result of hypoventilation and hypoxia due to the increased mechanical load of excess body fat. However, in recent years it has been proposed that the metabolic and inflammatory disturbances of obesity may also play a role in the development of PAH. To determine whether PAH develops in obese rats in the absence of hypoxia, we assessed pulmonary hemodynamics and pulmonary artery (PA) structure in the diet-resistant/diet-induced obesity (DR/DIO) and Zucker lean/fatty rat models. We found that high-fat feeding (DR/DIO) or overfeeding (Zucker) elicited PA remodeling, neomuscularization of distal arterioles, and elevated PA pressure, accompanied by right ventricular (RV) hypertrophy. PA thickening and distal neomuscularization were also observed in DIO rats on a low-fat diet. No evidence of hypoventilation or chronic hypoxia was detected in either model, nor was there a correlation between blood glucose or insulin levels and PAH. However, circulating inflammatory cytokine levels were increased with high-fat feeding or calorie overload, and hyperlipidemia and oxidant damage in the PA wall correlated with PAH in the DR/DIO model. We conclude that hyperlipidemia and peripheral inflammation correlate with the development of PAH in obese subjects. Obesity-related inflammation may predispose to PAH even in the absence of hypoxia.

To compare the prevalence of cardiovascular disease (CVD) and major CVD risk factors among rheumatoid arthritis (RA) patients enrolled in a large US and multinational registry. We compared CVD and CVD risk factor prevalence from 11 countries enrolled in the CORRONA US and CORRONA International registries; patients from the 10 ex-US participating countries were grouped by region (Eastern Europe, Latin America, and India). Unadjusted summary data were presented for demographics and disease characteristics; comparisons for prevalence of CVD risk factors and CVD were age/gender standardized to the age/gender distribution of the US enrolled patients. Overall, 25,987 patients were included in this analysis. Compared to patients from the ex-US regions, US participants had longer disease duration and lower disease activity, yet were more likely to receive a biologic agent. Additionally, CORRONA US participants had the highest body mass index (BMI). Enrolled patients in India had the lowest BMI, were more rarely smokers, and had a low prevalence of hyperlipidemia, hypertension, and prior CVD compared to the US and other ex-US regions. Participants from Eastern Europe had a higher prevalence of hypertension and hyperlipidemia and highest prevalence of all manifestations of CVD. Differences in the prevalence of both CVD and major CVD risk factors were observed across the four regions investigated. Observed differences may be influenced by variations in both non-modifiable/modifiable characteristics of patient populations, and may contribute to heterogeneity on the observed safety of investigational and approved therapies in studies involving RA patients from different origins.

Non-alcoholic fatty liver disease (NAFLD) is the most common liver disease in the United States. Binge eating disorder (BED) is the most common form of eating disorder. NAFLD and BED have similar risk factors, including obesity, insulin resistance, and metabolic syndrome. The aim of our study was to examine prevalence of BED in NAFLD patients. We administered the Binge Eating Scale (BES), a questionnaire validated to screen for BED, to NAFLD patients at our Fatty Liver Center. Demographics were retrieved retrospectively from our electronic medical record. Of the total 95 NAFLD patients screened, 22 (23.1%) had binge eating tendencies; 6 of the 22 (6.3%) scored 27 or more points, suggestive of severe binge eating. Patient demographics included 59 females and 36 males (14 females and 8 males positive for BED). Liver disease severity and of metabolic syndrome presence were similar in both groups: 45 patients had steatosis, 25 steatohepatitis, and 24 cirrhosis, of which 10 steatosis, 5 steatohepatitis, and 7 cirrhosis patients screened positive for BED. Of the NAFLD patients with BED, 50.0% had insulin resistance, 68.2% hypertension, and 50.0% hyperlipidemia, whereas among non-BED NAFLD patients 58.9% had insulin resistance, 63.0% hypertension, and 67.1% hyperlipidemia. This pilot study suggests that BED may have a higher prevalence among NAFLD patients than in the general population. Based on these preliminary results, further study into the prevalence of BED is recommended. More data is need to identify effects of BED on the progression of NAFLD and role of BED treatment.

Elevated concentration of any or all types of lipids in the plasma including hypertriglyceridemia and hypercholesterolemia leads to atherosclerotic cardiovascular disease. Effective medication needs multiple drug therapy as recommended cholesterol and triglyceride levels are difficult to achieve by monotherapy and frequently require the use of more than one lipid-lowering medication. Gemfibrozil lowers plasma triglyceride-rich lipoproteins mainly VLDL and increases HDL. It is associated with short plasma half-life (1.5h) and GIT distress on long term use. In a study it was found that ethanolamine decreases serum cholesterol, especially VLDL cholesterol and LDL cholesterol in rats fed an HF/HC diet. In the present work, we thought of exploring the effect of co-drug of gemfibrozil with ethanolamine (GE-I) as a potential combination therapy for the management of mixed hyperlipidemia. Synthesis of GE-I was effected by CDI coupling. Structure was confirmed spectrally. Interestingly kinetic studies revealed that GE-I resisted chemical and enzymatic hydrolysis. In tritoninduced hyperlipidemia, significant lowering of serum lipid levels was observed. The hallmark of GEI was its profound effect on HDL level which was raised above the normal level by 15%. Docking study also supported modulatory effect of GE-I (docking score -7.012) on PPAR-α which was comparable to docking score of gemfibrozil (-9.432). These preliminary observations prompt us to consider GE-I as a novel, serendipitous, hybrid anti-hyperlipidemic new chemical entity which needs be studied extensively to prove it as an HDL enhancing anti-hyperlipidemic agent.

The effect of coffee on cardiovascular diseases is still controversial. It is known that the process of decaffeination may influence the chemical constitution and, therefore, the biological effects of coffee. This study thus evaluated the effects of decaffeination on the levels of total phenols and chlorogenic acids in Coffea arabica L. samples, as well as the effects of ingesting both integral and decaffeinated coffee on the lipid profile and hemostatic and hematological parameters in normal and hyperlipidemic rats. Samples of integral and decaffeinated lyophilized coffee (Coffea arabica L., planted in Brazil) were used for chemical analysis (total phenols, chlorogenic acid and caffeine contents). For the bioassays, coffee beverages were prepared with non-lyophilized samples (10% w/v) and were filtered and administered to animals by gavage (7.2 mL/kg/day) over 30 days. On the 31st day after beginning the treatment with coffee beverages, hyperlipidemia was induced to the animals by administering Triton WR-1339 (300 mg/kg body weight). On day 32, blood was taken to determine the lipid profile, platelet aggregation, prothrombin time, partially activated thromboplastin time and hemogram. The contents of both phenolic compounds and chlorogenic acid in the integral coffee beverage were significantly lower than those in the decaffeinated coffee beverage. The animals treated with Triton WR-1339 presented a mixed hyperlipidemia. Although the decaffeination process caused a relative increase in total phenols and chlorogenic acids, the coffee drinks were unable to change the lipid profile or the hemostatic and hematological parameters in the studied animals.

To report outcomes following ligation and bypass (LGB) surgery for popliteal artery aneurysm (PAA) and study factors influencing patient and graft survival. A retrospective review of patients undergoing LGB surgery for PAA between September 1999 and August 2012 at a tertiary referral vascular unit was performed. Primary graft patency (PGP), primary-assisted graft patency (PAGP), and secondary graft patency (SGP) rates were calculated using survival analyses. Patient, graft aneurysm-free survival (GAFS), aneurysm reperfusion-free survival (ARFS), and amputation-free survival (AFS) rates were also calculated. Log-rank testing and Cox proportional hazards modeling were used to perform univariate and multivariate analysis of influencing factors, respectively. Eighty-four LGB repairs in 69 patients (mean age 71.3 years, 68 males) were available for study. The 5-year PGP, PAGP, SGP, and patient survival rates were 58.1%, 84.4%, 85.2%, and 81.1%, respectively. On multivariate analysis, the principal determinants of PGP were urgency of operation ( P = .009) and smoking status ( P = .019). The principal determinants of PAGP were hyperlipidemia status ( P = .048) and of SGP were hyperlipidemia ( P = .042) and cerebrovascular disease (CVD) status ( P = .045). The principal determinants of patient survival were previous myocardial infarction ( P = .004) and CVD ( P = .001). The 5-year GAFS, ARFS, and AFS rates were 87.9%, 91.6%, and 96.1%, respectively. This study has shown that traditional cardiovascular risk factors, such as a smoking and ischemic heart disease, are the most important predictors of early graft failure and patient death following LGB surgery for PAA.

In Taiwan, the prevalence of hyperlipidemia increased due to lifestyle and dietary habit changes. Low density lipoprotein cholesterol (LDL-C) and non-high density lipoprotein cholesterol (non-HDL-C) are all significant predicting factors of coronary artery disease in Taiwan. We recognized that lipid control is especially important in patients with existed atherosclerotic cardiovascular diseases (ASCVD), including coronary artery disease (CAD), ischemic stroke and peripheral arterial disease (PAD). Because the risk of ASCVD is high in patients with diabetes mellitus (DM), chronic kidney disease (CKD) and familial hypercholesterolemia (FH), lipid control is also necessary in these patients. Lifestyle modification is the first step to control lipid. Weight reduction, regular physical exercise and limitation of alcohol intake all reduce triglyceride (TG) levels. Lipid-lowering drugs include HMG-CoA reductase inhibitors (statins), cholesterol absorption inhibitors (ezetimibe), proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors, nicotinic acids (niacin), fibric acids derivatives (fibrates), and long-chain omega-3 fatty acids. Statin is usually the first line therapy. Combination therapy with statin and other lipid-lowering agents may be considered in some clinical settings. For patients with acute coronary syndrome (ACS) and stable CAD, LDL-C < 70 mg/dL is the major target. A lower target of LDL-C <55 mg/dL can be considered in ACS patients with DM. After treating LDL-C to target, non-HDL-C can be considered as a secondary target for patients with TG ≥ 200 mg/dL. The suggested non-HDL-C target is < 100 mg/dL in ACS and CAD patients. For patients with ischemic stroke or transient ischemic attack presumed to be of atherosclerotic origin, statin therapy is beneficial and LDL-C < 100 mg/dL is the suggested target. For patients with symptomatic carotid stenosis or intracranial arterial stenosis, in addition to antiplatelets and blood pressure control, LDL-C should be lowered to < 100 mg/dL. Statin is necessary for DM patients with CV disease and the LDL-C target is < 70 mg/dL. For diabetic patients who are ≥ 40 years of age, or who are < 40 years of age but have additional CV risk factors, the LDL-C target should be < 100 mg/dL. After achieving LDL-C target, combination of other lipid-lowering agents with statin is reasonable to attain TG < 150 mg/dL and HDL-C >40 in men and >50 mg/dL in women in DM. LDL-C increased CV risk in patients with CKD. In adults with glomerular filtration rate (GFR) < 60 mL/min/1.73m 2 without chronic dialysis (CKD stage 3-5), statin therapy should be initiated if LDL-C ≥ 100 mg/dL. Ezetimibe can be added to statin to consolidate the CV protection in CKD patients. Mutations in LDL receptor, apolipoprotein B and PCSK9 genes are the common causes of FH. Diagnosis of FH usually depends on family history, clinical history of premature CAD, physical findings of xanthoma or corneal arcus and high levels of LDL-C. In addition to conventional lipid lowering therapies, adjunctive treatment with mipomersen, lomitapide, or PCSK9 inhibitors become necessary to further reduce LDL-C in patients with FH. Overall, these recommendations are to help the health care professionals in Taiwan to treat hyperlipidemia with current scientific evidences. We hope the prescription rate of lipid lowering drugs and control rate of hyperlipidemia in high risk patients could be increased by implementation of the clinical guidelines. The major purpose is to improve clinical outcomes of these high risk patients through the control of hyperlipidemia. Copyright © 2016. Published by Elsevier B.V.

By virtue of insulin resistance being the common etiology for polycystic ovary syndrome (PCOS) and metabolic syndrome, the cardiometabolic risks of these two syndromes are shared. The usual concerns of a PCOS patient are cosmetic or reproductive. However, there are more serious concerns past the reproductive age. Early treatment of insulin resistance, hypertension and hyperlipidemia reduces the long-term risk. This review highlights the unhealthy association of metabolic syndrome with PCOS and emphasizes the importance of early diagnosis, patient education and long-term follow-up beyond the reproductive age into menopause to prevent the long-term serious co-morbidities.

Gemfibrozil is long known for its ability to reduce the level of triglycerides in the blood circulation and to decrease the risk of hyperlipidemia. However, a number of recent studies reveal that apart from its lipid-lowering effects, gemfibrozil can also regulate many other signaling pathways responsible for inflammation, switching of T-helper cells, cell-to-cell contact, migration, and oxidative stress. In this review, we have made an honest attempt to analyze various biological activities of gemfibrozil and associated mechanisms that may help to consider this drug for different human disorders as primary or adjunct therapy.

2003-12-01

HIV infection is associated with a number of metabolic abnormalities, including lipodystrophy, a difficult-to-define disorder whose characteristics include hyperlipidemia, insulin resistance, and fat redistribution. Current data suggest that lipodystrophy is caused by multiple factors. Dual-nucleoside reverse transcriptase inhibitor therapy combined with protease inhibitor therapy has been shown to increase the risk of metabolic abnormalities, but susceptibility independent of drug effects has also been shown. While many of the treatments for the broad range of signs and symptoms of lipodystrophy bring about improvements in patient status, none have been demonstrated to bring about a return to baseline levels.

The effectiveness of Hibiscus sabdariffa L. (HS) in the treatment of risk factors associated with cardiovascular disease is assessed in this review by taking a comprehensive approach to interpreting the randomized clinical trial (RCT) results in the context of the available ethnomedical, phytochemical, pharmacological, and safety and toxicity information. HS decoctions and infusions of calyxes, and on occasion leaves, are used in at least 10 countries worldwide in the treatment of hypertension and hyperlipidemia with no reported adverse events or side effects. HS extracts have a low degree of toxicity with a LD50 ranging from 2,000 to over 5,000mg/kg/day. There is no evidence of hepatic or renal toxicity as the result of HS extract consumption, except for possible adverse hepatic effects at high doses. There is evidence that HS acts as a diuretic, however in most cases the extract did not significantly influence electrolyte levels. Animal studies have consistently shown that consumption of HS extract reduces blood pressure in a dose dependent manner. In RCTs, the daily consumption of a tea or extract produced from HS calyxes significantly lowered systolic blood pressure (SBP) and diastolic blood pressure (DBP) in adults with pre to moderate essential hypertension and type 2 diabetes. In addition, HS tea was as effective at lowering blood pressure as the commonly used blood pressure medication Captropril, but less effective than Lisinopril. Total cholesterol, low-density lipoprotein cholesterol (LDL-C), and triglycerides were lowered in the majority of normolipidemic, hyperlipidemic, and diabetic animal models, whereas high-density lipoprotein cholesterol (HDL-C) was generally not affected by the consumption of HS extract. Over half of the RCTs showed that daily consumption of HS tea or extracts had favorable influence on lipid profiles including reduced total cholesterol, LDL-C, triglycerides, as well as increased HDL-C. Anthocyanins found in abundance in HS calyxes are generally considered the phytochemicals responsible for the antihypertensive and hypocholesterolemic effects, however evidence has also been provided for the role of polyphenols and hibiscus acid. A number of potential mechanisms have been proposed to explain the hypotensive and anticholesterol effects, but the most common explanation is the antioxidant effects of the anthocyanins inhibition of LDL-C oxidation, which impedes atherosclerosis, an important cardiovascular risk factor. This comprehensive body of evidence suggests that extracts of HS are promising as a treatment of hypertension and hyperlipidemia, however more high quality animal and human studies informed by actual therapeutic practices are needed to provide recommendations for use that have the potential for widespread public health benefit.

Modern clinical usually use estrogen replacement therapy and with long time application with lots of side effect appear. Traditional Chinese medicine has more secure and effective methords,using warming Yang drugs and methods. And the previous study proves the Chinese medicine Astragali Complanati Semen water extraction has a good role in regulation of blood lipids. Because of the liver is the most important organ on regulating metabolism, therefore this study aimed to evaluate the effects of total flavonoids in Astragali Complanati Semen(TFS)on liverlipid level and ERα expressionon liver in hyperlipidemia rats with kidney-Yang deficiency pattern to explore the substance basis and mechanism of Astragali Complanati Semen in regulate lipid effect and clarify traditional Chinese medicine advantages and features. This experiment uses hyperlipidemia rats with kidney-Yang deficiency pattern with bilateral ovariectomized and fed with high fat diet for 6 weeks. And rats of sham operation group and model group rats were intragastrilly(ig) with saline, estrogen group were intragastrilly with estrogen(0.2 mg·kg⁻¹). And three TFS group were intragastrilly with TFS at dose 28.5, 57, 114 mg·kg⁻¹ for 8 weeks. At the same time, TC, TG, LDL-C,HDL-C liver weight, liver index, uterine weight, uterine index, serum estrogen level, FSH levels and liver pathology, liver estrogen receptor expression were detected, weighting and calculating their organ index. The experimental results compared with the model group, TFS 114 mg·kg⁻¹ decreased the level of liver TG ( P <0.05), TC ( P <0.001) and LDL-C ( P <0.001) and increased the level of HDL-C ( P <0.05). Compared with the model group, estrogen group increased the level of blood serum ( P <0.001) and decreased the level of FSH ( P <0.001). In addition, compared with sham operation group,model group decreased the protein expression of ERα（ P <0.01）. Compared with the model group, estrogen group increased the protein expression of ERα significantly（ P <0.001）.TFS mid-dose group and TFS high-dose group is increased the protein expression of ERα（ P <0.01, P <0.001）.In a conclusion,Flavonoids is the main active ingredient of Astragali Complanati Semen. The mechanism of it maybe is enhancing the estrogen receptor sensitivity or the number of estrogen receptors, amplifying the signal after the receptor conduction, which could result in lipid-lowering effect.

Analysis of the prevalence of and factors associated with overactive bladder in adult Korean women

PubMed Central

2017-01-01

Background Overactive bladder (OAB) is one of the most prevalent lower urinary tract conditions and has been suggested to be related to various factors. We assessed the prevalence of and factors associated with OAB in women based on a large cross-sectional, population-based study of adult Korean women. Methods The Korean community health survey (KCHS) of 2012 was reviewed, and 107,950 female participants aged 19 to 107 years were identified for inclusion in this study. The overactive bladder symptom score (OABSS) was used to define and classify OAB as mild, moderate, or severe. Numerous variables, including marital status; physical activity; education and income levels; type of occupation; body mass index (BMI); smoking; alcohol; sleep time; and medical history of hypertension, diabetes mellitus, hyperlipidemia, or cerebral stroke, were evaluated. The correlation of these variables with the prevalence of OAB was analyzed using simple and multiple logistic regression analyses with complex sampling. Results The results showed that 5.2% of adult women experienced OAB. Multiple regression analyses showed a significant correlation between the following variables and OAB: older age (adjusted odds ratio [AOR] = 1.44, 95% confidence interval [CI] = 1.39–1.50, P < 0.001 as 10 years older); married status (AOR = 0.83, 95%CI = 0.70–0.96, P = 0.016); lower level of income (AOR = 1.50, 95%CI = 1.34–1.68, P < 0.001); high BMI (AOR = 1.33, 95%CI = 1.23–1.44, P < 0.001); smoking (AOR = 1.24, 95%CI = 1.04–1.47, P < 0.001); long sleep time (AOR = 1.95, 95%CI = 1.69–2.26); and medical history of hypertension (AOR = 1.11, 95%CI = 1.03–1.21, P = 0.011), diabetes mellitus (AOR = 1.38, 95%CI = 1.25–1.53, P < 0.001), hyperlipidemia (AOR = 1.27, 95%CI = 1.16–1.39, P < 0.001), and cerebral stroke (AOR = 2.04, 95%CI = 1.73–2.41, P < 0.001). The level of stress showed a dose-dependent association with OAB (AOR [95%CI] = 3.28 [2.81–3.83] > 2.11 [1.91–2.33] >1.28 [1.16–1.41] for severe > moderate > some stress, respectively, P < 0.001). Conclusion The prevalence of OAB was approximately 5.2% among adult Korean women. Older age; high BMI; stress level; sleep duration; levels of income and education; marital status; smoking; and medical history of hypertension, diabetes mellitus, hyperlipidemia, and cerebral stroke were significantly related to OAB in women.

The effectiveness of Hibiscus sabdariffa L. (HS) in the treatment of risk factors associated with cardiovascular disease is assessed in this review by taking a comprehensive approach to interpreting the randomized clinical trial (RCT) results in the context of the available ethnomedical, phytochemical, pharmacological, and safety and toxicity information. HS decoctions and infusions of calyxes, and on occasion leaves, are used in at least 10 countries worldwide in the treatment of hypertension and hyperlipidemia with no reported adverse events or side effects. HS extracts have a low degree of toxicity with a LD50 ranging from 2,000 to over 5,000 mg/kg/day. There is no evidence of hepatic or renal toxicity as the result of HS extract consumption, except for possible adverse hepatic effects at high doses. There is evidence that HS acts as a diuretic, however in most cases the extract did not significantly influence electrolyte levels. Animal studies have consistently shown that consumption of HS extract reduces blood pressure in a dose dependent manner. In RCTs, the daily consumption of a tea or extract produced from HS calyxes significantly lowered systolic blood pressure (SBP) and diastolic blood pressure (DBP) in adults with pre to moderate essential hypertension and type 2 diabetes. In addition, HS tea was as effective at lowering blood pressure as the commonly used blood pressure medication Captropril, but less effective than Lisinopril. Total cholesterol, low-density lipoprotein cholesterol (LDL-C), and triglycerides were lowered in the majority of normolipidemic, hypolipidemic, and diabetic animal models, whereas high-density lipoprotein cholesterol (HDL-C) was generally not affected by the consumption of HS extract. Over half of the RCTs showed that daily consumption of HS tea or extracts had favorable influence on lipid profiles including reduced total cholesterol, LDL-C, triglycerides, as well as increased HDL-C. Anthocyanins found in abundance in HS calyxes are generally considered the phytochemicals responsible for the antihypertensive and hypocholesterolemic effects, however evidence has also been provided for the role of polyphenols and hibiscus acid. A number of potential mechanisms have been proposed to explain the hypotensive and anticholesterol effects, but the most common explanation is the antioxidant effects of the anthocyanins inhibition of LDL-C oxidation, which impedes atherosclerosis, an important cardiovascular risk factor. This comprehensive body of evidence suggests that extracts of HS are promising as a treatment of hypertension and hyperlipidemia, however more high quality animal and human studies informed by actual therapeutic practices are needed to provide recommendations for use that have the potential for widespread public health benefit.

We previously demonstrated that plasminogen activator inhibitor-1 (PAI-1), an inhibitor of fibrinolysis, is involved in type 1 diabetic bone loss in female mice. PAI-1 is well known as an adipogenic factor induced by obesity. We therefore examined the effects of PAI-1 deficiency on bone and glucose and lipid metabolism in high-fat and high-sucrose diet (HF/HSD)-induced obese female mice. Female wild-type (WT) and PAI-1-deficient mice were fed with HF/HSD or normal diet for 20 weeks from 10 weeks of age. HF/HSD increased the levels of plasma PAI-1 in WT mice. PAI-1 deficiency suppressed the levels of blood glucose, plasma insulin, and total cholesterol elevated by obesity. Moreover, PAI-1 deficiency improved glucose intolerance and insulin resistance induced by obesity. Bone mineral density (BMD) at trabecular bone as well as the levels of osterix, alkaline phosphatase, and receptor activator of nuclear factor κB ligand mRNA in tibia were decreased by HF/HSD in WT mice, and those changes by HF/HSD were not affected by PAI-1 deficiency. HF/HSD increased the levels of plasma TNF-α in both WT and PAI-1-deficient mice, and the levels of plasma TNF-α were negatively correlated with trabecular BMD in tibia of female mice. In conclusion, we revealed that PAI-1 deficiency does not affect the trabecular bone loss induced by obesity despite the amelioration of insulin resistance and hyperlipidemia in female mice. Our data suggest that the changes of BMD and bone metabolism by obesity might be independent of PAI-1 as well as glucose and lipid metabolism.

Cost sharing is widely used to encourage therapeutic substitution. This study aimed to examine the impact of increases in patient cost-sharing differentials for brand name and generic drugs on statin utilization on entry into the Medicare Part D coverage gap. Using 5% Medicare Chronic Condition Warehouse files from 2006, this quasi-experimental study examined patients with hyperlipidemia who filled prescriptions for atorvastatin or rosuvastatin between January and March 2006. Propensity score matching and difference-in-difference regressions were used to compare changes in statin utilization for the study group (patients who were not eligible for low-income subsidies [non-LIS] and had generic-only gap coverage) to those of a control group (LIS patients who faced the same cost sharing before and during the Part D coverage gap). In the final sample, 801 patients in the study group were matched to 801 patients in the control group. We found that, compared to the control group, the study group had a larger decline in any monthly brand-name statin use (-0.24 30-day fills, P<0.001). This was only partially offset by increased monthly generic statin use (+0.06 30-day fill, P<0.001), with an overall drop in any monthly statin use (-0.18 30-day fills, P<0.001). Overall adherence with statins declined (OR 0.81, P<0.001), and statin discontinuation increased (OR 1.62, P<0.001) in the study group as compared to the control group. Increases in cost-sharing differentials for brand name and generic drugs on coverage gap entry were associated with discontinuation of statins in Medicare Part D patients with hyperlipidemia. © 2016 The Authors.

Abstract Background HIV-infected individuals have an increased risk of avascular bone necrosis (AVN). Antiretroviral therapy (ART) and particularly protease inhibitors (PI) have been implicated as a risk factor. We aimed to study the associations of ART with the occurrence of AVN among Swiss HIV Cohort Study participants (SHCS). Methods We used incidence density sampling to perform a case control study within the Swiss HIV Cohort Study (SHCS) comparing prospectively collected AVN cases and controls by conditional logistic regression analysis. To evaluate the effect of ART, multivariable models were adjusted for HIV transmission risk group, age, alcohol consumption, use of corticosteroids, CD4 nadir, maximum viral load, and pancreatitis. Results We compared 74 AVN cases and 145 controls. Associations with AVN were shown for heterosexual HIV acquisition (odds ratio [OR], 3.4; 95% confidence interval [CI], 1.1–10), alcohol consumption (OR, 2.7; 95% CI, 1.3–5.7), and hyperlipidemia (OR, 3.6; 95% CI, 1.4–9.6). After adding ART substances to the multivariable base model, there was evidence of an association for treatment with tenofovir (TDF) >1 year (OR, 4.4; 95% CI, 1.4–14) with AVN. Neither exposure to specific frequently prescribed ART combinations or ART drug classes nor cumulative ART exposure showed any associations with AVN. Conclusions In the HIV-infected population, a combination of risk factors such as heterosexual HIV acquisition, moderate to severe alcohol intake, and hyperlipidemia seem to contribute to AVN. ART does not seem to be a relevant risk factor for AVN. The association of prolonged TDF exposure with AVN needs to be confirmed. PMID:29026869

Approximately 1 in 5 hospitalized COPD patients are readmitted within 30 days of discharge. CHF coexists in more than 20% of patients with COPD, and is associated with early readmission for COPD. Reducing 30-day hospital readmissions for COPD is of intense current interest. A retrospective chart review was performed to identify patients discharged with COPD exacerbation and HFrEF. The primary objective was to evaluate if discharge medication prescribing following guidelines for both COPD and HFrEF correlates with reduced 30-day readmission rates. The study included 281 admissions with 39.1% prescribed appropriate discharge medications for both COPD and HFrEF; 30-day readmission rate was 24.5% for these patients compared to 31.1% that were not prescribed appropriate medications (p = 0.24). Beta blockers, ACE inhibitors or ARBS, and aldosterone antagonists were under-prescribed, but this did not significantly associate with increased readmission (p = 0.51, p = 0.23 or 0.99, and p = 0.18, respectively). Those prescribed hydralazine or nitrates were more likely to readmit (both p = 0.01). Diabetes and hyperlipidemia were associated with increased readmission (p = 0.01 and 0.05). This study did not show a significant difference in 30-day readmission rate based on appropriate discharge medications for both COPD and HFrEF. The comorbidities diabetes and hyperlipidemia and prescription of hydralazine or nitrates were significantly associated with increased readmission rate. Larger patient populations may be needed to assess if guideline based discharge medication prescribing is associated with reduced 30-day readmissions for COPD. Copyright © 2016 Elsevier Ltd.

Lipoprotein (a) [Lp(a)] is an independent risk factor for cardiovascular disease. There are currently limited therapeutic options to lower Lp(a) levels. L-Carnitine has been reported to reduce Lp(a) levels. The aim of this study was to compare the effect of L-carnitine/simvastatin co-administration with that of simvastatin monotherapy on Lp(a) levels in subjects with mixed hyperlipidemia and elevated Lp(a) concentration. Subjects with levels of low-density lipoprotein cholesterol (LDL-C) >160 mg/dL, triacylglycerol (TAG) >150 mg/dL and Lp(a) >20 mg/dL were included in this study. Subjects were randomly allocated to receive L-carnitine 2 g/day plus simvastatin 20 mg/day (N = 29) or placebo plus simvastatin 20 mg/day (N = 29) for a total of 12 weeks. Lp(a) was significantly reduced in the L-carnitine/simvastatin group [-19.4%, from 52 (20-171) to 42 (15-102) mg/dL; p = 0.01], but not in the placebo/simvastatin group [-6.7%, from 56 (26-108) to 52 (27-93) mg/dL, p = NS versus baseline and p = 0.016 for the comparison between groups]. Similar significant reductions in total cholesterol, LDL-C, apolipoprotein (apo) B and TAG were observed in both groups. Co-administration of L-carnitine with simvastatin was associated with a significant, albeit modest, reduction in Lp(a) compared with simvastatin monotherapy in subjects with mixed hyperlipidemia and elevated baseline Lp(a) levels.

Lipid-lowering therapy (LLT) is suboptimally used in patients with hyperlipidemia in the 2 highest statin benefit groups (SBGs), as categorized by the American College of Cardiology and the American Heart Association. This study estimated the social value of reducing low-density lipoprotein cholesterol (LDL-C) levels by 50% for patients in SBGs 1 and 2 who have been treated with standard LLT but have not reached LDL-C goal, as well as the potential value of PCSK9 inhibitors for patients in these groups. Simulation model. We used National Health and Nutrition Examination Surveys (NHANES) and US Census data to project the population of SBGs 1 and 2 in the time period 2015 to 2035. We used insurance claims data to estimate incidence rates of major adverse cardiac events (MACEs), and NHANES with National Vital Statistics data to estimate cardiovascular disease mortality rates. Using established associations between LDL-C and MACE risk, we estimated the value of reducing LDL-C levels by 50%. We incorporated results from a meta-analysis to estimate the value of PSCK9 inhibitors. Among those treated with LLT with LDL-C > 70 mg/dL in SBGs 1 and 2, the cumulative value of reducing LDL-C levels by 50% would be $2.9 trillion from 2015 to 2035, resulting primarily from 1.6 million deaths averted. The cumulative value of PCSK9 inhibitors would range from $3.4 trillion to $5.1 trillion (1.9-2.8 million deaths averted), or $12,000 to $17,000 per patient-year of treatment. Lowering LDL-C in high-risk patients with hyperlipidemia has enormous potential social value. For patients in these high-risk groups, PCSK9 inhibitors may have considerable net value depending on the final prices payers ultimately select.

Body mass index (BMI) and lifestyle-related physical illnesses have been implicated in the pathology of depression. We aimed to investigate the association of depression wih BMI classification (i.e., underweight, normal, overweight, and obese), metabolic disease, and lifestyle using a web-based survey in a large cohort. Participants were 1000 individuals who have had depression (mean age: 41.4 ± 12.3 years, 501 men) and 10,876 population-based controls (45.1 ± 13.6 years, 5691 men). The six-item Kessler scale (K6) test was used as a psychological distress scale. Compared to in the controls, obesity and hyperlipidemia were more common and frequency of a snack or night meal consumption was higher, whereas frequencies of breakfast consumption and vigorous and moderate physical activities were lower in the patients. K6 test scores were higher for underweight or obese people compared to normal or overweight people. A logistic regression analysis showed that the K6 test cut-off score was positively associated with being underweight, hyperlipidemia, and the frequency of a snack or night meal consumption, whereas it was negatively associated with the frequency of breakfast consumption in the patients. Logistic regression analyses showed that self-reported depression was positively associated with metabolic diseases and the frequency of a snack or night meal consumption, whereas it was negatively associated with the frequency of breakfast consumption. The observed associations of depression with BMI classification, metabolic disease, and lifestyle suggest that lifestyle and related physical conditions are involved in at least a portion of depressive disorders.

Electronic decision-support tools may help to improve management of hyperlipidemia and other chronic diseases. This study examined the impact of lipid management tools integrated into an electronic medical record (EMR) in primary care practices. This randomized controlled trial was conducted in a national network of physicians who use an outpatient EMR. Adult primary care physicians were randomized by office to receive an electronic form that was embedded in the EMR. The form contained prompts regarding suboptimal care based on Adult Treatment Panel-III (ATP-III) guidelines, as well as reporting tools to identify patients outside of office visits whose lipid management was suboptimal. All active patients, ages 20-79 years, whose physicians participated in the study, were categorized as high, moderate, or low cardiovascular risk, and the proportion who were tested for hyperlipidemia, at lipid goal, and on lipid-lowering medications if not at goal were measured according to ATP-III guidelines. A total of 105 physicians from 25 offices and 64,150 patients were included in the study. Outcomes improved for most measures from before to 1 year after the intervention (November 1, 2005 to October 31, 2006). However, after controlling for confounding variables and for clustering in multilevel modeling, only up-to-date lipid testing for high-risk patients was statistically better in the intervention group as compared to the control group (adjusted odds ratio 15.0, P < 0.05). This study showed few differences in quality of lipid management after implementing an EMR-based disease management intervention in primary care settings. Future studies may need to examine more comprehensive interventions that include office staff in a team approach to care.

Purpose Elastin is a major arterial structural protein, and elastin-derived peptides are related to arterial change. We previously reported on a novel assay developed using aortic elastin peptides; however, its clinical implications remain unclear. In this study, we assessed whether anti-elastin antibody titers reflect the risk of coronary artery disease (CAD) or its characteristics. Materials and Methods We included 174 CAD patients and 171 age- and sex-matched controls. Anti-elastin antibody titers were quantified by enzyme-linked immunosorbent assay. Parameters of arterial stiffness, including the augmentation index (AI) and heart-to-femoral pulse wave velocity (hfPWV), were measured non-invasively. The clinical and angiographic characteristics of CAD patients were also evaluated. Associations between anti-elastin levels and vascular characteristics were examined by linear regression analysis. Results The median blood level of anti-elastin was significantly lower in the CAD group than in the controls [197 arbitrary unit (a.u.) vs. 63 a.u., p<0.001]. Levels of anti-elastin were significantly lower in men and in subjects with hypertension, diabetes mellitus, hyperlipidemia, or high hfPWV. Nevertheless, anti-elastin levels were not dependent on atherothrombotic events or the angiographic severity of CAD. In a multivariate analysis, male sex (β=-0.38, p<0.001), diabetes mellitus (β=-0.62, p<0.001), hyperlipidemia (β=-0.29, p<0.001), and AI (β=-0.006, p=0.02) were ultimately identified as determinants of anti-elastin levels. Conclusion Lower levels of anti-elastin are related to CAD. The association between antibody titers and CAD is linked to arterial stiffness rather than the advancement of atherosclerosis.

Almond consumption is associated with ameliorations in obesity, hyperlipidemia, hypertension, and hyperglycemia. The hypothesis of this 12-week randomized, crossover, controlled feeding trial was that almond consumption would ameliorate inflammation and oxidative stress in Chinese patients with type 2 diabetes mellitus (T2DM) (9 M, 11 F; 58 years; BMI: 26 kg/m²) with mild hyperlipidemia. After a 2-week run-in period, the patients were assigned to either a control NCEP step II diet (control diet) or almond diet for 4 weeks with a 2-week washout period between alternative diets. Almonds approximately at 56 g/day were added to the control diet to replace 20 % of total daily calorie intake. As compared to the control diet, the almond diet decreased IL-6 by a median 10.3 % (95 % confidence intervals 5.2, 12.6 %), CRP by a median 10.3 % (-24.1, 40.5), and TNF-α by a median 15.7 % (-0.3, 29.9). The almond diet also decreased plasma protein carbonyl by a median 28.2 % (4.7, 38.2) as compared to the C diet but did not alter plasma malondialdehyde. The A diet enhanced the resistance of LDL against Cu²⁺-induced oxidation by a median 16.3 % (7.4, 44.3) as compared to the C diet. Serum intercellular adhesion molecule-1 and vascular adhesion molecule-1 were not changed by both diets. Our results suggested that incorporation of almonds into a healthy diet could ameliorate inflammation and oxidative stress in patients with T2DM.

Dietary fiber can reduce insulin resistance, body weight, and hyperlipidemia depending on fiber type, water solubility, and viscosity. PolyGlycopleX® (PGX®) is a natural, novel water soluble, non-starch polysaccharide complex that with water forms a highly viscous gel compared to other naturally occurring dietary fiber. We determined the effect of dietary PGX® vs. cellulose and inulin on the early development of insulin resistance, body weight, hyperlipidemia, and glycemia-induced tissue damage in young Zucker diabetic rats (ZDFs) in fasted and non-fasted states. ZDFs (5 weeks old) were fed a diet containing 5% (wgt/wgt) cellulose, inulin, or PGX® for 8 weeks. Body weight, lipids, insulin, and glucose levels were determined throughout the study and homeostasis model assessment (HOMA) was used to measure insulin sensitivity throughout the study in fasted animals. At study termination, insulin sensitivity (oral glucose tolerance test, OGTT) and kidney, liver, and pancreatic histopathology were determined. Body weight and food intake were significantly reduced by PGX® vs. inulin and cellulose. Serum insulin in fasted and non-fasted states was significantly reduced by PGX® as was non-fasted blood glucose. Insulin resistance, measured as a HOMA score, was significantly reduced by PGX® in weeks 5 through 8 as well as terminal OGTT scores in fed and fasted states. Serum total cholesterol was also significantly reduced by PGX®. PGX® significantly reduced histological kidney and hepatic damage in addition to reduced hepatic steatosis and cholestasis. A greater mass of pancreatic β-cells was found in the PGX® group. PGX® therefore may be a useful dietary additive in the control of the development of the early development of the metabolic syndrome.

Purpose: To study the preventive and therapeutic Hypolipidemic effect of different coconut oil extracts of Vyosakatvivaradi formulation. Method: High fat diet was fed for 21 days to induce Hyperlipidemia. 110 weanling wistar rats randomly divided in to Eleven groups, four in treatment, four in preventive group, two control and one standarad group. Four test drugs – 1. VCO (virgin coconut oil) + HERBS, 2. TCO (Traditional coconut oil) + HERBS, 3. CCO (Commercial coconut oil) + HERBS, 4. TCO + Coconut Milk + HERBS were administered at the dose rate of 0.06ml tid orally for 28 days in treatment group and 28 days in preventive group from the day one of experiment and the results were compared with Simvastatin 10 mg. All the animals were anesthetized using anesthetic ether and pooled blood samples from each group were collected on day Zero, day 21st and on termination day i.e. day 28th after start of actual treatment. Result: Animals in all groups did not reveal any change in their behavior or visible adverse reaction throughout the experimental period. Statistically significant reduction in mean triglyceride values in test drug -4 animals revealed preventive. Statistically significant reduction in the mean cholesterol level (mg/dl) was observed in test drug -4 animals. Statistically significant increase in the mean HDL level 5% level of significance was observed in preventive dose of test drug 3. Microscopic observations of liver, kidney and aorta revealed no significant change. Conclusion: The medicated oil “CCO + HERBS” and TCO + Coconut Milk + HERBS” showed encouraging therapeutic and preventive effects on hyperlipidemia. However, the oil “TCO + Coconut Milk + HERBS” is observed to be better than the oil CCO + HERBS. Though the oils “VCO + HERBS” and “TCO + HERBS” exhibited moderate hypolipidemic action.

To examine socioeconomic inequalities in the prevalence of chronic diseases in Serbia, using the data from 2006 national health survey. A stratified sample of 7673 households was selected and 14522 household members older than 20 years were interviewed (response rate 80.5%). Wealth index was used as a measure of socioeconomic status. Standardized morbidity prevalence ratios were computed using the poorest category as reference. Odds ratios for the prevalence of the selected chronic diseases and their 95% confidence intervals were calculated by multivariate logistic analysis adjusted for age, education, smoking status, and body mass index. Hypertension was the most prevalent disease in all socioeconomic categories; standardized morbidity prevalence ratios were higher in richer men (151.3 in the richest) and lower in richer women (86.1 in the richest). Rheumatism/arthritis was the second most prevalent disease in both sexes, with the highest prevalence in the poorest group; the pattern remained the same after standardization (standardized morbidity prevalence ratio in the richest: 86.4 in men and 74.0 in women). The prevalence of hyperlipidemia was associated with wealth index in both men and women and was highest in the richest group; the pattern remained the same after standardization (standardized morbidity prevalence ratio in the richest: 275.9 in men and 138.4 in women). Logistic regression models showed that higher wealth index was associated with higher prevalence of hypertension, hyperlipidemia, and allergy, while lower wealth index was associated with higher prevalence of rheumatism/arthritis. There were considerable socioeconomic inequalities in the prevalence of chronic diseases in Serbia. These results indicate an opportunity to reduce inequalities and show a need for further investigation on the determinants of chronic diseases.

To compare the clinical features, management, and in-hospital outcomes of patients with ST elevation myocardial infarction (STEMI) and non-ST elevation acute coronary syndrome (NSTEACS), in the Western Region of Saudi Arabia. A total of 71 patients were enrolled in a longitudinal study at a tertiary hospital without cardiac catheterization facility. These data were collected from Saudi Project for Assessment of Coronary Events registry. Twenty-three patients with STEMI were compared to 48 patients with NSTEACS. Mean age for STEMI was younger, 57.4±13.7 years compared to 63.2±13.9 years respectively (p=0.19). Forty-four percent arrived at the hospital by ambulance. History of hypertension and hyperlipidemia were more frequent in NSTEACS (p=0.05), while both groups showed no difference in diabetes mellitus, 17% vs 22% and smoking, 30% vs 17%. In-hospital medications were: Aspirin (100%) both groups, Clopidogrel (91% vs 100%) (p=0.03). There was more aggressive use of beta-blockers (74% vs 95%) (p=0.01) and statins (87% vs 100%) (p=0.01) in NSTEACS. In-hospital outcomes showed one recurrent myocardial infarction and one death in NSTEACS group (2%). Other outcome in the two groups showed recurrent ischemia (13% vs 29%) (p=0.14) and cardiogenic shock (9% vs 2%) (p=0.17). No stroke or major bleeding was reported in both groups. NSTEACS patients in western province of KSA present at an older age are mostly males and have higher prevalence of hypertension and hyperlipidemia compared with STEMI patients. It is therefore important to identify patients with high-risk profile and put implement measures to reduce these factors. Copyright © 2015 Cardiological Society of India. Published by Elsevier B.V.

We assessed the ability of LDL from 30 type 1 diabetic patients (18 men, 12 women), 65 type 2 diabetic patients (35 men, 30 women), and 35 controls (19 men, 16 women) to generate peroxides. The men and women in the diabetic groups were studied separately and matched for age, body mass index, duration of diabetes, glycohemoglobin, and conventional lipid characteristics according to the presence or absence of hyperlipidemia. The ability of LDL to form peroxides was assessed by measuring the thiobarbituric acid-reactive substances corrected for LDL-cholesterol [ratio of malondialdehyde (MDA) to LDL-cholesterol]. LDL particle size was expressed as the ratio of LDL-cholesterol to apolipoprotein B (LDL-cholesterol/apoB). The MDA/LDL-cholesterol ratio was higher in type 1 and type 2 diabetic patients with hyperlipidemia than in controls. The MDA/LDL-cholesterol ratio was also higher in type 2 normolipidemic women than in controls (P <0.01). The LDL-cholesterol/apoB ratio was lower in type 2 diabetic women than in type 2 diabetic men (P <0.05). The MDA/LDL-cholesterol ratio was negatively correlated with the LDL-cholesterol/apoB ratio (r = -0.78, P <0.001) in hyperlipidemic type 1 (not type 2) diabetic patients. In normolipidemic type 2 diabetic patients, the MDA/LDL-cholesterol ratio was also negatively correlated with the LDL-cholesterol/apoB ratio (r = -0.75, P <0.001) because of the highly significant negative correlation in type 2 diabetic women (r = -0.89, P <0.01). LDL from well-controlled type 2 diabetic women is smaller and more prone to form peroxides. This could explain why diabetic women are at greater risk of cardiovascular disease.

The aim of this study is to compare the non-lipid effects of rosuvastatin-fenofibrate combination therapy with rosuvastatin monotherapy in high-risk Asian patients with mixed hyperlipidemia. A total of 236 patients were initially screened. After six weeks of diet and life style changes, 180 of these patients were randomly assigned to receive one of two regimens: rosuvastatin 10 mg plus fenofibrate 160 mg or rosuvastatin 10 mg. The primary outcome variables were the incidences of muscle or liver enzyme elevation. The patients were followed for 24 weeks during drug treatment and for an additional four weeks after drug discontinuation. The rates of the primary outcome variables were similar between the two groups (2.8% and 3.9% in the combination and the rosuvastatin groups, respectively, p=1.00). The combination group had more, but not significantly, common treatment-related adverse events (AEs) (13.3% and 5.6%, respectively) and drug discontinuation due to AEs (10.0% and 3.3%, respectively) than the rosouvastatin group. Combination therapy was associated with higher elevations in homocysteine, blood urea nitrogen, and serum creatinine, whereas elevation in alanine aminotransferase was greater in the rosuvastatin group. Leukocyte count and hemoglobin level decreased to a greater extent in the combination group. The combination group showed greater reductions in TG and elevation in HDL-cholesterol. In our study population, the rosuvastatin-fenofibrate combination resulted in comparable incidences of myo- or hepatotoxicity as rosuvastatin monotherapy. However, this combination may need to be used with caution in individuals with underlying pathologies such as renal dysfunction (NCT01414803). Copyright © 2012 Elsevier Ireland Ltd.

To provide an evidence-based assessment of metabolic syndrome, hypertension, and hyperlipidemia in first-degree relatives of women with polycystic ovary syndrome (PCOS). Systematic review and meta-analysis. Not applicable. Mothers, fathers, sisters, and brothers of women with and without PCOS. An electronic-based search with the use of PubMed from 1960 to June 2015 and cross-checked references of relevant articles. Metabolic syndrome, hypertension and dyslipidemia, and surrogate markers, including systolic blood pressure (BP), diastolic BP, total cholesterol, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, and triglycerides. Fourteen of 3,346 studies were included in the meta-analysis. Prevalence of the following was significantly increased in relatives of women with PCOS: metabolic syndrome (risk ratio [RR] 1.78 [95% confidence interval 1.37, 2.30] in mothers, 1.43 [1.12, 1.81] in fathers, and 1.50 [1.12, 2.00] in sisters), hypertension (RR 1.93 [1.58, 2.35] in fathers, 2.92 [1.92, 4.45] in sisters), and dyslipidemia (RR 3.86 [2.54, 5.85] in brothers and 1.29 [1.11, 1.50] in fathers). Moreover, systolic BP (mothers, sisters, and brothers), total cholesterol (mothers and sisters), low-density lipoprotein cholesterol (sisters), and triglycerides (mothers and sisters) were significantly higher in first-degree relatives of PCOS probands than in controls. Our results show evidence of clustering for metabolic syndrome, hypertension, and dyslipidemia in mothers, fathers, sisters, and brothers of women with PCOS. PROSPERO 2016 CRD42016048557.

Leukocyte activation has been associated with vascular complications in type 2 diabetes mellitus (T2DM). Hyperglycemia may be involved in this leukocyte activation. Our aim was to investigate the role of elevated glucose concentrations on leukocyte activation in patients with a wide range of insulin sensitivity. Leukocyte activation was determined after ingestion of 75 gram glucose in subjects with T2DM, familial combined hyperlipidemia (FCH) and healthy controls. Leukocyte activation markers were measured by flow cytometry. Postprandial changes were calculated as the area under the curve (AUC), and the incremental area under the curve corrected for baseline values (dAUC). 51 Subjects (20 T2DM, 17 FCH and 14 controls) were included. Fasting neutrophil CD66b expression and CD66b-AUC were respectively 36% and 39% higher in T2DM patients than in controls (p=0.004 and p=0.003). Fasting neutrophil CD66b expression correlated positively with glucose-AUC (Spearman's rho 0.481, p<0.001) and HbA1c (rho 0.433, p=0.002). Although fasting monocyte CD11b expression was not significantly different between subjects, monocyte CD11b-AUC was 26% higher in T2DM than in controls (p=0.006). Similar trends were observed for FCH patients. Monocyte CD11b-dAUC correlated positively with glucose-AUC (rho 0.322, p=0.022) and HbA1c (rho 0.319, p=0.023). These data suggest that both acute and chronic hyperglycemia, associated with insulin resistance as seen in T2DM and FCH, are involved in the increased fasting and postprandial leukocyte activation observed in these conditions.

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.

Individuals infected with human immunodeficiency virus (HIV) are at increased risk for cardiovascular disease (CVD) events compared with uninfected persons. However, little is known about HIV provider practices regarding aspirin (ASA) for primary prevention of CVD. A cross-sectional study was conducted among patients attending the University of Alabama at Birmingham 1917 HIV Clinic during 2010 to determine the proportion receiving ASA for primary prevention of CVD and identify factors associated with ASA prescription. Ten-year risk for CVD events was calculated for men aged 45-79 and women aged 55-79. The 2009 US Preventive Services Task Force (USPSTF) guidelines were used to determine those qualifying for primary CVD prevention. Among 397 patients who qualified to receive ASA (mean age, 52.2 years, 94% male, 36% African American), only 66 (17%) were prescribed ASA. In multivariable logistic regression analysis, diabetes mellitus (odds ratio [OR], 2.60; 95% confidence interval [CI], 1.28-5.27), hyperlipidemia (OR, 3.42; 95% CI, 1.55-7.56), and current smoking (OR, 1.87; 95% CI, 1.03-3.41) were significantly associated with ASA prescription. Odds of ASA prescription more than doubled for each additional CVD-related comorbidity present among hypertension, diabetes, hyperlipidemia, and smoking (OR, 2.13, 95% CI, 1.51-2.99). In this HIV-infected cohort, fewer than 1 in 5 patients in need received ASA for primary CVD prevention. Escalating likelihood of ASA prescription with increasing CVD-related comorbidity count suggests that providers may be influenced more by co-occurrence of these diagnoses than by USPSTF guidelines. In the absence of HIV-specific guidelines, interventions to improve HIV provider awareness of and adherence to existing general population guidelines on CVD risk reduction are needed.

This study aimed to understand the impact of garlic on improving blood lipids using a meta-analysis. A literature search of the PubMed, EMBASE, and Cochrane Library databases was performed using keywords such as "garlic" and "hypercholesterolemia," and the deadline "July 14 (th), 2017." After extracting relevant details, each selected literature was evaluated for quality according to the quality evaluation criteria of bias risk recommended by Cochrane Collaboration recommendations and heterogeneity tests were performed. Standardized mean difference (SMD) and 95% confidence interval (CI) were evaluated using R 3.12 software. The publication bias was assessed using Egger method. A total of 14 eligible papers published from 1981 to 2016 were included. The quality of the literatures was of moderate to high qualities. The values of TC (SMD = -1.26, 95% CI, -1.86 to -0.66), low-density lipoprotein (LDL) (SMD = -1.07, 95% CI, -1.67 to -0.47), and high-density lipoprotein (HDL) (SMD = 0.50, 95% CI, 0.06-0.94) after taking garlic in the experimental group and the control group have statistical significance, while there was no significant difference of TG in the 2 groups (SMD = -0.16, 95% CI, -0.87-0.55). However, the result of HDL was reversed when removed some of the literatures. No significant publication bias among the eligible studies with values of TC (P = .0625), LDL (P = .0770), HDL (P = .2293), and TG (P = .3436). Garlic can reduce the level of TC and LDL instead of HDL and TG, indicating the ability of anti-hyperlipidemia.

To analyze psoriasis risk in type 2 diabetes mellitus (T2DM) patients treated in German primary care practices. The study included 87,964 T2DM patients aged 40 years or over who received their initial diabetes diagnosis between 2004 and 2013. Patients were excluded if they had been diagnosed with psoriasis prior to diabetes diagnosis or if the observation period prior to the index date was less than 365 days. After applying these exclusion criteria, 72,148 T2DM patients were included. A total of 72,148 non-diabetic controls were matched (1:1) to T2DM cases based on age, gender, type of health insurance (private or statutory), number of medical visits, and index date. The primary outcome was the diagnosis of psoriasis. Skin infections, dermatitis/eczema, hyperlipidemia, and medications associated with psoriasis (beta blockers, angiotensin-converting enzyme (ACE) inhibitors, lithium, antimalarials, nonsteroidal anti-inflammatory drugs, and benzodiazepines) were included as potential confounders. The mean age was 68.7 years (SD=12.7 years) and 48.6% of subjects were men. Hyperlipidemia, dermatitis/eczema, and skin infections were more frequent in T2DM patients than in controls. Beta blockers, ACE inhibitors, and nonsteroidal anti-inflammatory drugs were also more commonly used in people with T2DM than in controls. A total of 3.4% of T2DM patients and 2.8% of matched controls developed psoriasis within ten years of follow-up (p-value <0.001). T2DM patients were at a higher risk of developing psoriasis than controls (HR=1.18, 95% CI: 1.08-1.29). T2DM was positively associated with psoriasis in patients treated in German primary care practices. Copyright © 2016 Primary Care Diabetes Europe. Published by Elsevier Ltd. All rights reserved.

To examine the prevalence and predictors of foot disease, self-care and clinical monitoring in adults with type 2 diabetes in Alberta, Canada. Baseline data from a prospective cohort of adults with type 2 diabetes were used. Assessment of foot disease included self-reported peripheral neuropathy, peripheral vasculopathy, foot or leg ulcer/infection or gangrene/amputation. Foot self-care was assessed using the Summary of Diabetes Self-Care Activities, and clinical monitoring using patients' reports of having feet checked for lesions or sensory loss. The mean age of respondents (N=2040) was 64 (SD 10.7) years; 45% were female, and 91% were Caucasian. Peripheral neuropathy was reported by 18% of the respondents, peripheral vasculopathy by 28%, ulcer/infection by 6% and gangrene/amputation by 1.4%. Only 14% of respondents performed foot self-care behaviours ≥6 days per week, and only 41% and 34% had their feet clinically checked for lesions or sensory loss, respectively. Predictors of foot disease included longer duration of diabetes, smoking, depressive symptoms, low self-efficacy and a history of cardiovascular diseases. Predictors of good self-care included older age, female sex, longer duration of diabetes and no report of hyperlipidemia. Predictors of clinical monitoring included female sex, current smoking, residing in urban areas, longer duration of diabetes, and histories of heart disease or hyperlipidemia. Peripheral neuropathy and vasculopathy were the most common reported foot problems in this population. Foot self-care is generally infrequent, and clinical monitoring is performed for less than half of these patients, with significant variations by patient demographics and clinical presentation.

Premature coronary artery disease (PCAD) seems to increase, particularly in developing countries. Given the lack of such studies in the country, this study examines the prevalence, associated cardiovascular risk factors, and coronary angiographic profile of the disease in Iraq. Data was collected from a total of 445 adult patients undergoing coronary angiography at Duhok Heart Center, Kurdistan in a period between March and September 2014. Patients were divided into PCAD (male <45 years and female < 55 years) and mature coronary artery disease (MCAD). The prevalence of the angiographically documented PCAD was 31 %. The PCAD had higher rates of hyperlipidemia (p = 0.04), positive family history of coronary artery disease (p = 0.002), type A lesions (p = 0.02), single vessel disease (p = 0.01) and medical treatment (p = 0.01) than the MCAD. Logistic regression model indicated that male sex (OR 3.38, C.I 1.96-7.22), smoking (OR 2.08, C.I 1.05-4.12), hypertension (OR 1.58, C.I 1.25-2.03), hyperlipidemia (OR 1.89, C.I 1.17-2.42) and positive family history of coronary artery disease (OR 2.62, C.I 1.38-9.54) were associated with the PCAD. Sensitivity analysis showed highest specificity (94.2 %) and positive predictive value (96.5 %) in patients with coronary stenosis >70 % compared to lesser obstruction. Premature coronary artery disease is alarming  in the country. Cardiovascular risk factors are clustered among them. But the angiographic profile and therapeutic options of PCAD are close to those reported from previous studies.

Potential use of cholesterol lipoprotein profile to confirm obesity status in dogs.

A common sign of obesity, in dogs, is hyperlipidemia, which is characterized by hypercholesterolemia and/or hypertriglycemia. Hyperlipidemia can be caused by a quantitative increase in circulating lipoproteins (LP) or by a higher lipid concentration in the various LP classes. In this study, we sought to determine whether aberrations occur with cholesterol lipoprotein profile, especially with sub HDL-cholesterol fraction % in obese dogs. Using clinically healthy and disease free (no overt signs) body condition score classified obese dogs, of all ages, we attempted to determine the influence of age, gender and obesity status on cholesterol lipoprotein profiling. Overall, no aberration in pattern was observed in obese dogs <8 years of age. However, in older obese animals (≥8 years of age), the general aberration pattern to cholesterol lipoprotein observed was that a significant decrease in HDL2 and 3 fraction % occurs with a concomitant increase in either HDL1-Cho or VLDL and LDL -Cho fraction % depending on gender. Linear regression analysis indicated that obesity status appears to significantly affect total cholesterol, HDL2 and 3-Cho, VLDL and LDL-Cho levels (P=0.02, 0.046, and 0.045, respectively), whereas it is borderline with HDL1-Cho (P=0.062). On the other hand, age significantly influenced TG, Total cholesterol, and HDL1-Cho levels (P=0.009, 0.006, and 0.002, respectively), while gender influenced VLDL and LDL-Cho (P=0.024) level. Therefore, aberrations in cholesterol lipoprotein profile pattern might be of potential use to assess and diagnose obesity status, in conjunction with BCS, especially of older overweight animals which might be considered borderline obese. © Springer Science+Business Media B.V. 2011

2010-10-01

To examine variation in outpatient prescription use and spending for hyperlipidemia and diabetes mellitus in the Veterans Affairs Healthcare System (VA) and its association with quality measures for these conditions. Cross-sectional. We compared outpatient prescription use, spending, and quality of care across 135 VA medical centers (VAMCs) in fiscal year 2008, including 2.3 million patients dispensed lipid-lowering medications and 981,031 patients dispensed diabetes medications. At each facility, we calculated VAMC-level cost per patient for these medications, the proportion of patients taking brand-name drugs, and Healthcare Effectiveness Data and Information Set (HEDIS) scores for hyperlipidemia (low-density lipoprotein cholesterol level <100 mg/dL) and for diabetes (glycosylated hemoglobin level >9% or not measured). The median cost per patient for lipid-lowering agents in fiscal year 2008 was $49.60 and varied from $39.68 in the least expensive quartile of VAMCs to $69.57 in the most expensive quartile (P < .001). For diabetes agents, the median cost per patient was $158.34 and varied from $123.34 in the least expensive quartile to $198.31 in the most expensive quartile (P < .001). The proportion of patients dispensed brand-name oral drugs among these classes in the most expensive quartile of VAMCs was twice that in the least expensive quartile (P < .001). There was no correlation between VAMC-level prescription spending and performance on HEDIS measures for lipid-lowering drugs (r = 0.12 and r = 0.07) or for diabetes agents (r = -0.10). Despite the existence of a closely managed formulary, significant variation in prescription spending and use of brand-name drugs exists in the VA. Although we could not explicitly risk-adjust, there appears to be no relationship between prescription spending and quality of care.

Purpose Danshen is the dried root extract of the plant Salvia Miltiorrhiza and it is used as traditional Chinese medicinal herbal product to prevent and treat atherosclerosis. However, its efficacy has not been thoroughly investigated. This study evaluates the effect of Danshen on hyperlipidemia and hypertension, two well known risk factors for the development of atherosclerosis. Methods This was a randomized, placebo-controlled, double-blind crossover study performed at a tertiary referral center. Participants were recruited by newspaper advertisement and randomized to treatment with Danshen (water-extract of the Salvia Miltiorrhiza root) or placebo for 4 consecutive weeks. There was a wash out period of 4 weeks. Of the 20 analysed participants, 11 received placebo first. Inclusion criteria were: age 40-70 years, hyperlipidemia and hypertension. At the end of each treatment period, plasma lipids were determined (primary outcome), 24 hours ambulant blood pressure measurement (ABPM) was performed, and vasodilator endothelial function was assessed in the forearm. Results LDL cholesterol levels were 3.82±0.14 mmol/l after Danshen and 3.52±0.16 mmol/l after placebo treatment (mean±SE; p<0.05 for treatment effect corrected for baseline). Danshen treatment had no effect on blood pressure (ABPM 138/84 after Danshen and 136/87 after placebo treatment). These results were further substantiated by the observation that Danshen had neither an effect on endothelial function nor on markers of inflammation, oxidative stress, glucose metabolism, hemostasis and blood viscosity. Conclusion Four weeks of treatment with Danshen (water-extract) slightly increased LDL-cholesterol without affecting a wide variety of other risk markers. These observations do not support the use of Danshen to prevent or treat atherosclerosis. Trial Registration ClinicalTrials.gov NCT01563770 PMID:26192328

Aripiprazole-Induced Hyperlipidemia: An Update.

PubMed

Tarraf, Caroline; Naja, Wadih J

2016-08-25

To review the literature on the metabolic side effects of aripiprazole. Three cases of aripiprazole-induced hypertriglyceridemia are also presented. A search was conducted of English-language articles and abstracts (meta-analyses, randomized controlled trials, clinical trials, naturalistic open-label trials, reviews, and case reports) published up to August 31, 2014, in electronic databases (PubMed, MEDLINE). Free-text and MeSH search keywords included aripiprazole, cholesterol, triglyceride, lipid profile, hyperlipidemia, and hypercholesterolemia and their differing terminations and combinations. The search was supplemented by a manual review of reference lists from the identified publications. Pediatric studies were excluded. Twenty-two articles were found and 3 aspects of the metabolic side effects of aripiprazole were reviewed: (1) the prevalence of the metabolic syndrome in mentally ill patients prior to any antipsychotic use to highlight the initial predisposition of this group of patients to develop the metabolic syndrome, (2) the prevalence of metabolic changes depending on the choice of antipsychotic (aripiprazole compared to other antipsychotics), and (3) metabolic changes reported after switching from an antipsychotic to aripiprazole. Patients with mental disorders are at high risk for developing dyslipidemia, diabetes, and the full criteria of the metabolic syndrome. Antipsychotic use exacerbates this risk, thus increasing the mortality in this population. Nevertheless, it seems that the risk for these side effects varies with each antipsychotic. Although by and large the literature supports the supposition that aripiprazole causes less metabolic effects than other antipsychotics, we report 3 cases of serious aripiprazole-related dyslipidemia in young subjects. On the basis of these 3 cases, aripiprazole can cause hypertriglyceridemia. Triglyceride levels should be carefully monitored in patients with mental disorders taking aripiprazole. © Copyright 2016 Physicians Postgraduate Press, Inc.

Context Recently, adenosine triphosphate (ATP) was occasionally found to decrease the triglyceride (TG) levels in several hyperlipidemic patients in our clinical practice. Objective The study investigates the anti-hyperlipidemic effects of ATP in a high-fat fed rabbit model and hyperlipidemic patients. Materials and methods Twenty-four rabbits were randomly divided into three groups of eight animals each as follows: normal diet, high-fat diet and high-fat diet + ATP group. ATP supplementation (40 mg/day) was started at the 20th day and lasted for 10 days. Serum concentrations of total cholesterol (TC), TG, LDL-C, HDL-C were measured on the 20th day and 30th day. Heart, liver and aorta were subjected histopathological examination. Twenty outpatients diagnosed primary hyperlipidemia took ATP at a dose of 60 mg twice a day for 1 week. Results Feeding rabbits with a high-fat diet resulted in a significant elevation of lipid parameters including TC, TG, LDL-C, VLDL-C compared to the normal diet group (p < 0.01). ATP treatment significantly decreased serum TG level (p < 0.01), whilst other parameters remained statistically unaltered. Meanwhile, ATP significantly reduced the thickness of fat layer in cardiac epicardium (p < 0.05) and pathological gradation of ballooning degeneration in hepatocytes (p < 0.05). After taking ATP for 1 week, hyperlipidemia patients exhibited a significant decrease of TG (p < 0.01), but other lipid parameters had no significant change. Discussion and conclusion The study indicates that ATP selectively decreases serum TG levels in high-fat diet rabbits and hyperlipidemic patients. Therefore, ATP supplementation may provide an effective approach to control TG level.

Elevated serum iron level is linked with an increased risk of diabetes and atherosclerosis. However, the pathological mechanism by which iron affects serum lipoprotein levels is unknown. To elucidate the mechanism, a high dose of ferrous ion was applied (final 60 µM, 120 µM) to human serum lipoproteins, macrophages, and human dermal fibroblast (HDF) cells. Iron-treated lipoproteins showed loss of antioxidant ability along with protein degradation and multimerization, especially co-treatment with fructose (final 10 mM). In the presence of fructose, HDF cells showed 3.5-fold more severe cellular senescence, as compared to the control, dependent on the dosage of fructose. In macrophages, phagocytosis of acetylated low-density lipoprotein (acLDL) was more accelerated by ferrous ion, occurring at a rate that was up to 1.8-fold higher, than acLDL alone. After 24 weeks supplementation with 0.05% and 0.1% ferrous ion in the diet (wt/wt), serum total cholesterol (TC) level was elevated 3.7- and 2.1-fold, respectively, under normal diet (ND). Serum triglyceride (TG) was elevated 1.4- and 1.7-fold, respectively, under ND upon 0.05% and 0.1% ferrous ion supplementation. Serum glucose level was elevated 2.4- and 1.2-fold under ND and high cholesterol diet (HCD), respectively. However, body weight was decreased by the Fe 2+ consumption. Iron consumption caused severe reduction of embryo laying and reproduction ability, especially in female zebrafish via impairment of follicular development. In conclusion, ferrous ion treatment caused more pro-atherogenic, and pro-senescence processes in human macrophages and dermal cells. High consumption of iron exacerbated hyperlipidemia and hyperglycemia as well as induced fatty liver changes and sterility along with reduction of female fertility.

Hyperlipidemia (HL) has been identified as a risk factor for rotator cuff tear, but no studies have evaluated its effects on healing. The purpose of this study was to evaluate the effect of HL and statin use on rotator cuff healing after arthroscopic repair. This was a retrospective review of 85 patients (86 shoulders) who underwent arthroscopic rotator cuff repair with postoperative ultrasound evaluation. Ultrasound findings were graded no retear, partial-thickness retear (PT), or full-thickness retear (FT). Average age was 62.1 years (45.3-74.3 years). On ultrasound evaluation, 65 shoulders (75.5%) had no retear, 14 (16.3%) had PT, and 7 (8.1%) had FT. There was no significant difference in retear rate by age, technique, or tissue quality. There were 33 patients (38.8%) who had the diagnosis of HL, and all were taking a statin medication. Compared with patients without HL, patients with HL had significantly higher rates of FT (18.1% vs. 1.9%; P < .001) and PT (27.2% vs. 9.4%; P < .001). The total retear rate (PT and FT) for HL patients was significantly higher at 45.5% (15/33) compared with the patients without HL at 11.3% (6/53), with an odds ratio of 6.5 (P < .001). There was no difference in retear rate by dosage or type of statin mediation. After arthroscopic rotator cuff repair, HL was a risk factor for retear. Further investigation is warranted on this topic, and these results may help in managing expectations after surgery. Copyright © 2017 Journal of Shoulder and Elbow Surgery Board of Trustees.

High plasma cholesterol levels are a major risk factor for atherosclerosis. Plasma cholesterol can be reduced by inhibiting lipoprotein production; however, this is associated with steatosis. Previously we showed that lentivirally mediated hepatic expression of microRNA-30c (miR-30c) reduced hyperlipidemia and atherosclerosis in mice without causing hepatosteatosis. Because viral therapy would be formidable, we examined whether a miR-30c mimic can be used to mitigate hyperlipidemia and atherosclerosis without inducing steatosis. Delivery of a miR-30c mimic to the liver diminished diet-induced hypercholesterolemia in C57BL/6J mice. Reductions in plasma cholesterol levels were significantly correlated with increases in hepatic miR-30c levels. Long term dose escalation studies showed that miR-30c mimic caused sustained reductions in plasma cholesterol with no obvious side effects. Furthermore, miR-30c mimic significantly reduced hypercholesterolemia and atherosclerosis in Apoe−/− mice. Mechanistic studies showed that miR-30c mimic had no effect on LDL clearance but reduced lipoprotein production by down-regulating microsomal triglyceride transfer protein expression. MiR-30c had no effect on fatty acid oxidation but reduced lipid synthesis. Additionally, whole transcriptome analysis revealed that miR-30c mimic significantly down-regulated hepatic lipid synthesis pathways. Therefore, miR-30c lowers plasma cholesterol and mitigates atherosclerosis by reducing microsomal triglyceride transfer protein expression and lipoprotein production and avoids steatosis by diminishing lipid syntheses. It mitigates atherosclerosis most likely by reducing lipoprotein production and plasma cholesterol. These findings establish that increasing hepatic miR-30c levels is a viable treatment option for reducing hypercholesterolemia and atherosclerosis. PMID:27365390

Food insecurity refers to the inability to afford enough food for an active, healthy life. Numerous studies have shown associations between food insecurity and adverse health outcomes among children. Studies of the health effects of food insecurity among adults are more limited and generally focus on the association between food insecurity and self-reported disease. We therefore examined the association between food insecurity and clinical evidence of diet-sensitive chronic disease, including hypertension, hyperlipidemia, and diabetes. Our population-based sample included 5094 poor adults aged 18-65 y participating in the NHANES (1999-2004 waves). We estimated the association between food insecurity (assessed by the Food Security Survey Module) and self-reported or laboratory/examination evidence of diet-sensitive chronic disease using Poisson regression. We adjusted the models to account for differences in age, gender, race, educational attainment, and income. Food insecurity was associated with self-reported hypertension [adjusted relative risk (ARR) 1.20; 95% CI, 1.04-1.38] and hyperlipidemia (ARR 1.30; 95% CI, 1.09-1.55), but not diabetes (ARR 1.19; 95% CI, 0.89-1.58). Food insecurity was associated with laboratory or examination evidence of hypertension (ARR 1.21; 95% CI, 1.04-1.41) and diabetes (ARR 1.48; 95% CI, 0.94-2.32). The association with laboratory evidence of diabetes did not reach significance in the fully adjusted model unless we used a stricter definition of food insecurity (ARR 2.42; 95% CI, 1.44-4.08). These data show that food insecurity is associated with cardiovascular risk factors. Health policy discussions should focus increased attention on ability to afford high-quality foods for adults with or at risk for chronic disease.

Both statins and higher serum cholesterol have been reported to reduce to risk of Parkinson Disease (PD). Given the importance of adjusting for cholesterol levels when evaluating the effect of statins, we assessed whether the protective effect of statins would remain when adjustment for cholesterol is performed. We conducted a systematic review of epidemiologic studies that reported quantitative estimates of the association between statins and incident PD and were published through February 2016. Random-effects meta-analysis was used to assess the effect of statins on PD separately among the studies that adjusted for either cholesterol or hyperlipidemia and studies that did not. Ten eligible studies that evaluated the use of statins and incident PD were identified. Among the six studies that did not adjust for cholesterol, a protective effect of statins was observed (relative risk 0.75; 95% confidence intervals (CI) 0.60 to 0.92). Excluding studies with possible bias because of reverse causation or stratifying on study design did not affect the results. No protective effect was observed among the four studies that adjusted for either cholesterol of hyperlipidemia (relative risk 0.91; 95%CI 0.68 to 1.22). The effect estimate for studies that adjusted for cholesterol was 1.04 (95%CI 0.68 to 1.59) when a study with immortal time bias was excluded. The apparent protective effect of statins on risk of PD is at least partially explained by confounding by statin indication. Immortal time bias and healthy user effects also could have contributed to biased results. Copyright © 2016 John Wiley & Sons, Ltd. Copyright © 2016 John Wiley & Sons, Ltd.

Cholesterol oversynthesis markers define familial combined hyperlipidemia versus other genetic hypercholesterolemias independently of body weight.

Primary hypercholesterolemia of genetic origin, negative for mutations in LDLR, APOB, PCSK9 and APOE genes (non-FH GH), and familial combined hyperlipidemia (FCHL) are polygenic genetic diseases that occur with hypercholesterolemia, and both share a very high cardiovascular risk. In order to better characterize the metabolic abnormalities associated with these primary hypercholesterolemias, we used noncholesterol sterols, as markers of cholesterol metabolism, to determine their potential differences. Hepatic cholesterol synthesis markers (desmosterol and lanosterol) and intestinal cholesterol absorption markers (sitosterol and campesterol) were determined in non-FH GH (n=200), FCHL (n=100) and genetically defined heterozygous familial hypercholesterolemia subjects (FH) (n=100) and in normolipidemic controls (n=100). FCHL subjects had lower cholesterol absorption and higher cholesterol synthesis than non-FH GH, FH and controls (P<.001). When noncholesterol sterols were adjusted by body mass index (BMI), FCHL subjects had higher cholesterol synthesis than non-FG GH, FH and controls (P<.001). An increase in BMI was accompanied by increased cholesterol synthesis and decreased cholesterol absorption in non-FH GH, FH and controls. However, this association between BMI and cholesterol synthesis was not observed in FCHL. Non-high-density-lipoprotein cholesterol showed a positive correlation with cholesterol synthesis markers similar to that of BMI in non-FH GH, FH and normolipemic controls, but there was no correlation in FCHL. These results suggest that FCHL and non-FH GH have different mechanisms of production. Cholesterol synthesis and absorption are dependent of BMI in non-FH GH, but cholesterol synthesis is increased as a pathogenic mechanism in FCHL independently of age, gender, APOE and BMI.

This study aimed to compare midterm and long-term weight loss and resolution of co-morbidity with laparoscopic Roux-en-Y gastric bypass (LRYGB) and laparoscopic sleeve gastrectomy (LSG). LRYGB and LSG are the most common procedures performed in bariatric surgery. However, their weight loss efficacy in the midterm and long-term has not been well compared. A meta-analysis was performed by systematically identifying comparative studies conducted until the end of June 2016 that investigated weight loss outcome and resolution of co-morbidities (type 2 diabetes mellitus, hypertension, hyperlipidemia, hypertriglyceridemia, and obstructive sleep apnea) with LRYGB and LSG in the midterm (3-5 years) and long term (≥5 years). The primary endpoint was weight loss after LRYGB versus LSG. The secondary endpoint was resolution of co-morbidities after these procedures. Fourteen studies comprising 5264 patients were eligible. Follow-up ranged from 36 months to 75.8±8.4 months. The pooled result for weight loss outcomes did not show any significant difference in midterm weight loss (standardized mean difference = -0.03; 95% confidence interval (CI), -0.38-.33; P = .88) but a significant difference in the long-term weight loss outcome favoring LRYGB (standardized mean difference = .17; 95% CI, .05-.28; P= .005). The pooled results demonstrated no significant difference for resolution of type 2 diabetes mellitus, hypertension, hyperlipidemia, and hypertriglyceridemia. Despite the insignificant difference between LRYGB and LSG in midterm weight loss, LRYGB produced better weight loss in the long-term. There was no significant difference between the 2 procedures for co-morbidity resolution. Copyright © 2017 American Society for Bariatric Surgery. Published by Elsevier Inc. All rights reserved.

[Exercise for prevention of osteoporosis and other lifestyle-related diseases].

The prevalence of lifestyle-related diseases including hypertension, dyslipidemia (hyperlipidemia) and diabetes increases with aging, and all these conditions are risk factors of arteriosclerotic diseases such as cerebrovascular event (stroke) and myocardial infarction. The term "metabolic domino" has been used to describe the collective concept of the development and progression of these lifestyle-related diseases, the sequence of events, and the progression process of complications. Like the first tile of a domino toppling game, undesirable lifestyle such as overeating and underexercising first triggers obesity, and is followed in succession by onset of an insulin resistance state (underlied by a genetic background indigenous to Japanese) , hypertension, hyperlipidemia, and further postprandial hyperglycemia (the pre-diabetic state) , the so-called metabolic syndrome, at around the same time. On the other hand, apart from the other lifestyle-related diseases, the prevalence of osteoporosis also increases rapidly accompanying aging. Osteoporosis is known to be strongly related to disorders due to the metabolic domino such as arteriosclerosis and vascular calcification, and a new disease category called "osteo-vascular interaction" has attracted attention recently. Regarding "osteo-vascular interaction" , a close relation between bone density loss or osteoporotic changes and vascular lesion-associated lifestyle-related diseases such as hypertension, dyslipidemia and diabetes has been reported. Therefore, as a common preventive factor for bone mass loss or osteoporosis and lifestyle-related diseases including hypertension, dyslipidemia and diabetes (osteo-vascular interaction) , exercise has been recognized anew as an important non-pharmaceutical therapy that should take top priority. This article overviews the evidence of exercise therapy for the prevention of osteoporosis and other lifestyle-related diseases, from the viewpoint of health promotion, especially of the skeletal system (motor system) .

To determine the percentage of physicians who reported counseling patients on diet/nutrition, exercise, weight reduction, or smoking cessation during their office visits when responding to the 2002 National Ambulatory Medical Care Survey (NAMCS). We sought to establish whether patients are receiving adequate counseling from physicians on the basis of this nationwide survey. Retrospective database analysis. United States. Data included 184,668,007 physician visits for patients diagnosed with type 2 diabetes, hyperlipidemia, hypertension, or obesity; 140,362,102 physician visits for patients in which insulin/oral antidiabetics, antihyperlipidemia drugs, angiotensin-converting enzyme inhibitors, thiazide diuretics, or weight loss drugs were prescribed; and 82,317,640 physician visits for patients who smoked or used tobacco. Not applicable. Frequency of responses for counseling/education/therapy about diet/nutrition, exercise, weight reduction, and tobacco use/exposure. For patients with type 2 diabetes, hyperlipidemia, or hypertension, or patients receiving a drug in one of the drug classes that may indicate the presence of these diseases, patients did not receive any type of diet or exercise counseling during more than one half of all visits. Visits by patients who were diagnosed as obese were most likely to receive any type of counseling (80.2%). Of visits for patients who used tobacco, 78.6% did not include any counseling about smoking cessation. Patients are insufficiently counseled and educated about the need for lifestyle changes that can affect their risks for common chronic diseases. As accessible and ideally positioned health care providers, pharmacists could potentially affect the rising epidemic of obesity and other lifestyle-related diseases by filling this void.

Prosopis cineraria (L.) Druce (Leguminosae) (syn. Prosopis spicigera L.) has antidiabetic and antioxidant potential. Earlier we reported its hypolipidemic activity obtained from ethanol extract (ET-PCF). Object of this work was to isolate ferulic acid (FA) from ET-PCF and evaluate hypolipidemic activity against high-fat diet (HFD)-induced hyperlipidemic laboratory rats. ET-PCF was subjected to flash column chromatography to isolate FA. The chemical structure of the isolated compound was elucidated by UV, IR, 1H NMR,13C NMR and LC-MS. Further, the antihyperlipidemic effect of FA (10, 20 and 40 mg/kg, p.o.) in HFD-induced hyperlipidemic rats was investigated. Hyperlipidemia was induced in male Sprague-Dawley rats by feeding with HFD for 60 days. Lipid parameters such as total cholesterol (TC), Low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C) and triglycerides (TG) levels were measured in serum and hepatic tissue. Hepatic oxido-nitrosative stress (SOD, GSH, MDA and NO) were also determined. Histological evaluation of liver tissue was carried out. The structure of the isolated compound was characterized based on spectral data and confirmed as FA. HFD induced an alteration in serum, and hepatic lipid profile (triglyceride, cholesterol, HDL, and LDL) was significantly restored (p < 0.001) by administration of FA (20 and 40 mg/kg, p.o.). The elevated level of oxido-nitrosative stress in liver was significantly reduced (p < 0.001) by FA (20 and 40 mg/kg, p.o.). Histological aberration induced in the liver after HFD ingestion were restored by FA administration. Ferulic acid isolated from ET-PCF showed hypolipidemic effects in HFD-induced hyperlipidemic rats via modulation of elevated oxido-nitrosative stress. PMID:28096790

Background: Hawthorn (Crataegus pinnatifida) fruit has enjoyed a great popularity as a pleasant-tasting food associated with hypolipidemic and antioxidant effects. Objective: Our aim was to screen the effective fraction of hawthorn fruit in the treatment of hyperlipidemia rats. Materials and Methods: In this study, ethanol extract of hawthorn fruit (Fr.1) and four fractionated extracts (Fr.2, Fr.3, Fr.4, and Fr.5) were compared to total phenol content evaluated using Folin–Ciocalteu method, and hypolipidemic and antioxidant effects were assessed in hyperlipidemic rats. Results: Total phenol content of Fr.4 was higher than other fractions by at least 2 fold. Furthermore, this fraction possessed the strongest hypolipidemic and antioxidant effects in hyperlipidemic rats. On this basis, 15 phenolic compounds and four organic acids in Fr.4 were positively or tentatively identified using ultra-performance liquid chromatography coupled with quadropole time-of-flight mass spectrometry. In addition, 5-O-caffeoyl quinic acid butyl ester was first reported in hawthorn fruit. Conclusion: Phenol-rich fraction in hawthorn fruit exhibited satisfactory hypolipidemic and antioxidant effects, and this could be exploited for further promotion of functional foods.

Dietary intake of whole grains reduces the incidence of chronic diseases such as obesity, diabetes, cardiovascular disease, and cancer. In an earlier study, we showed that Panicum miliaceum L. extract (PME) exhibited the highest anti-lipogenic activity in 3T3-L1 cells among extracts of nine different cereal grains tested. In this study, we hypothesized that PME in the diet would lead to weight loss and augmentation of hyperlipidemia by regulating fatty acid metabolism. PME was fed to ob/ob mice at 0%, 0.5%, or 1% (w/w) for 4 weeks. After the experimental period, body weight changes, blood serum and lipid profiles, hepatic fatty acid metabolism-related gene expression, and white adipose tissue (WAT) fatty acid composition were determined. We found that the 1% PME diet, but not the 0.5%, effectively decreased body weight, liver weight, and blood triglyceride and total cholesterol levels (P < 0.05) compared to obese ob/ob mice on a normal diet. Hepatic lipogenic-related gene (PPARα, L-FABP, FAS, and SCD1) expression decreased, whereas lipolysis-related gene (CPT1) expression increased in animals fed the 1% PME diet (P < 0.05). Long chain fatty acid content and the ratio of C18:1/C18:0 fatty acids decreased significantly in adipose tissue of animals fed the 1% PME diet (P < 0.05). Serum inflammatory mediators also decreased significantly in animals fed the 1% PME diet compared to those of the ob/ob control group (P < 0.05). These results suggest that PME is useful in the chemoprevention or treatment of obesity and obesity-related disorders. PMID:22259675

Cardiometabolic risk (CMR) factors including hypertension, overweight/obesity, diabetes mellitus, and hyperlipidemia are high among United States ethnic minorities, and the immigrant population continues to burgeon. Hypothesizing that acculturation (length of residence) would be associated with a higher prevalence of CMR factors, the authors analyzed data on 54, 984 US immigrants in the 2010-2014 National Health Interview Surveys. The main predictor was length of residence. The outcomes were hypertension, overweight/obesity, diabetes mellitus, and hyperlipidemia. The authors used multivariable logistic regression to examine the association between length of US residence and these CMR factors.The mean (SE) age of the patients was 43 (0.12) years and half were women. Participants residing in the United States for ≥10 years were more likely to have health insurance than those with <10 years of residence (70% versus 54%, P<0.001). After adjusting for region of birth, poverty income ratio, age, and sex, immigrants residing in the United States for ≥10 years were more likely to be overweight/obese (odds ratio [OR], 1.19; 95% CI, 1.10-1.29), diabetic (OR, 1.43; 95% CI, 1.17-1.73), and hypertensive (OR, 1.18; 95% CI, 1.05-1.32) than those residing in the United States for <10 years. In an ethnically diverse sample of US immigrants, acculturation was associated with CMR factors. Culturally tailored public health strategies should be developed in US immigrant populations to reduce CMR. © 2016 The Authors.

Cerebrovascular disease is a leading cause of morbidity and mortality worldwide, which is influenced by genetic and environmental factors. The aim of the present study was to examine the association between single-nucleotide polymorphisms (SNPs) in Notch3 exons 3-6 and lacunar infarction by comparing SNPs between control subjects and those with lacunar infarction. A single-center case-control study was conducted to investigate the association between Notch3 SNPs and risk of stroke. A total of 140 patients were included in the study, 30 of whom had no infarction (control) and 110 had lacunar infarction. Lacunar patients were divided into the 'pure lacunar' and 'lacunar + leukoarasis' groups based on brain imaging. All the patients were of Chinese Han ethnicity, and the male to female ratio was 84:56. Patient clinical histories included hypertension, diabetes mellitus (DM), hyperlipidemia, and heart disease were recorded. The Notch3 sequence was obtained from the National Centser for Biotechnology Information database. Notch3 was amplified by polymerase chain reaction from whole blood samples, and exons 3-6 were sequenced to identify SNPs. The result showed that there was no significant difference in the prevalence of hypertension, DM, hyperlipidemia, and heart disease between the control and lacunar infarction patients. Notabley, the age of the lacunar + leukoarasis patients was significantly higher than that of the control and pure lacunar patients (P<0.05). Eight SNPs were detected at low frequencies, and only rs3815388 and rs1043994 exhibited slightly higher frequencies. A χ 2 test indicated that Notch3 SNPs, particularly rs1043994, were associated with lacunar infarction (P<0.05). In conclusion, the result of the present study have shown that Notch3 SNPs, particularly rs1043994, are associated with lacunar infarction.

Heart failure (HF) is a serious complication of acute coronary syndromes (ACS), and is associated with high in-hospital mortality and poor long-term survival. The aims of this study were to describe the clinical characteristics, management and in-hospital outcomes of coronary syndrome (ACS) patients with HF in the United Arab Emirates. The study was selected from the Gulf Registry of Acute Coronary Events (Gulf RACE), a prospective multi-national, multicenter registry of patients hospitalized with ACS in six Middle East countries. The present analysis was focused on participants admitted to various hospitals in the UAE with a diagnosis of ACS in 2007 and were analyzed in terms of HF (Killip class II/III and IV) on admission. Of 1691 patients (mean age: 52.6 ± 11.7 years; 210 Females, 1481 Males) with ACS, 356 (21%) had an admission diagnosis of HF (Killip class II/III and IV). HF patients were less frequently males (19.2% vs. 34.3%; P < 0.001). HF was more frequently associated with hypertension (64.3% vs. 43.9%; P < 0.001), hyperlipidemia (49.4% vs. 31.8%; P < 0.001) and diabetes mellitus (DM) (51.1% vs. 36.2%; P < 0.001). HF was significantly associated with in-hospital mortality (OR = 11.821; 95% CI: 5.385-25.948; P < 0.001). In multivariate logistic regression, age, hyperlipidemia, heart rate and DM were associated with higher in-hospital HF. HF is observed in about 1 in 5 patients with ACS in the UAE and is associated with a significant increase in in-hospital mortality and other adverse outcomes.

Behavioral indicators characterizing specific features of the pathological process of alimentary-dependent diseases were studied using in vivo model of alimentary hyperlipidemia in rats and mice. Rats and mice of the control groups received balanced semisynthetic diet for 63 days; animals of the experimental groups received a diet with high fat content (30% dry weight), balanced or high-fat diet with fructose solution instead of water, balanced cholesterol-enriched diet (0.5% dry weight), or balanced cholesterol-enriched diet with fructose solution. During the experiment, the mass of food, consumed by the animals, was monitored daily. Muscle tone was assessed by the front paw grip strength on days 33 and 54 of the experiment. Anxiety was tested in the elevated plus maze on days 36 and 57. Behavior and memory were assessed by conditioned passive avoidance reflex on days 39, 40, and 61. A significant increase in muscle tone was revealed on day 54 in rats fed with a balanced diet with fructose, and in mice, that received a similar diet, supplemented with fructose and cholesterol. Anxiety in the second test (day 57) was significantly decreased in rats fed high-fat diet and increased in mice fed high fat diet and high fat diet with fructose. In the second test, additional amount of cholesterol in the diet was the factor that significantly improved both short-term and long-term memory in both species. In mice, in contrast to rats, addition of fructose, including combination with high-fat diet, significantly worsened short-term and long-term memory. Thus, dietary factors, contributing to alimentary dyslipidemia development in rats and mice, can significantly affect the indices of neuromotor activity, anxiety level and cognitive functions, and the nature and direction of these changes are largely species-specific.

Background Paeoniflorin is a monoterpene glycoside extracted from the roots of Paeonia lactiflora and is used in Chinese herbal medicine to treat hyperlipidemia. The aim of this study was to evaluate the effects of an enriched extract of paeoniflorin on cholesterol levels, hemodynamics, and oxidative stress in a hyperlipidemic rat model. Material/Methods Male Sprague-Dawley rats were fed high-cholesterol diets and treated with three different doses of paeoniflorin for 12 weeks. The effects of paeoniflorin treatment were assessed on cholesterol levels, cholesterol metabolism, red blood cell vascular flow using hemorheology, antioxidant enzymes, and expression of the rate-limiting enzyme in the mevalonate pathway, 3-hydroxy-3-methylglutharyl-coenzyme A reductase (HMG-CoAR). Rat liver histology and immunohistochemical analysis were performed to evaluate the expression of nuclear factor erythroid 2–related factor 2 (Nrf2), cytochrome P450 7A1 (CYP7A1), and peroxisome proliferator-activated receptors (PPAR)-α. Protein expression HMG-CoAR, low-density lipoprotein receptor (LDLR), PPAR-α and CYP7A1 was measured by Western blotting. Antioxidant activity in rat liver was determined by measuring superoxide dismutase (SOD) and malondialdehyde (MDA). Results Serum and hepatic cholesterol, hepatic steatosis and the products of cholesterol metabolism were reduced by paeoniflorin treatment, which also reduced the activity of HMG-CoAR and upregulated the expression of LDLR, PPAR-α, and CYP7A1 expression, increased SOD, decreased MDA, and upregulated Nrf2 expression. Conclusions The findings of this study in a rat model of hyperlipidemia have shown that paeoniflorin regulates hepatic cholesterol synthesis and metabolism and may also protect the liver from oxidative stress.

Recent studies suggested that green tea has the potential to protect against diet-induced obesity. The presence of caffeine within green tea has caused limitations. Cocoa tea (Camellia ptilophylla) is a naturally decaffeinated tea plant. To determine whether cocoa tea supplementation results in an improvement in high-fat diet-induced obesity, hyperlipidemia and hepatic steatosis, and whether such effects would be comparable to those of green tea extract, we studied six groups (n = 10) of C57BL/6 mice that were fed with (1) normal chow (N); (2) high-fat diet (21% butterfat + 0.15% cholesterol, wt/wt) (HF); (3) a high-fat diet supplemented with 2% green tea extract (HFLG); (4) a high-fat diet supplemented with 4% green tea extract (HFHG); (5) a high-fat diet supplemented with 2% cocoa tea extract (HFLC); and (6) a high-fat diet supplemented with 4% cocoa tea extract (HFHC). From the results, 2% and 4% dietary cocoa tea supplementation caused a dose-dependent decrease in (a) body weight, (b) fat pad mass, (c) liver weight, (d) total liver lipid, (e) liver triglyceride and cholesterol, and (f) plasma lipids (triglyceride and cholesterol). These data indicate that dietary cocoa tea, being naturally decaffeinated, has a beneficial effect on high-fat diet-induced obesity, hepatomegaly, hepatic steatosis, and elevated plasma lipid levels in mice, which are comparable to green tea. The present findings have provided the proof of concept that dietary cocoa tea might be of therapeutic value and could therefore provide a safer and cost effective option for patients with diet-induced metabolic syndrome.

Dietary fiber can reduce insulin resistance, body weight, and hyperlipidemia depending on fiber type, water solubility, and viscosity. PolyGlycopleX(®) (PGX(®)) is a natural, novel water soluble, non-starch polysaccharide complex that with water forms a highly viscous gel compared to other naturally occurring dietary fiber. We determined the effect of dietary PGX(®) vs. cellulose and inulin on the early development of insulin resistance, body weight, hyperlipidemia, and glycemia-induced tissue damage in young Zucker diabetic rats (ZDFs) in fasted and non-fasted states. ZDFs (5 weeks old) were fed a diet containing 5% (wgt/wgt) cellulose, inulin, or PGX(®) for 8 weeks. Body weight, lipids, insulin, and glucose levels were determined throughout the study and homeostasis model assessment (HOMA) was used to measure insulin sensitivity throughout the study in fasted animals. At study termination, insulin sensitivity (oral glucose tolerance test, OGTT) and kidney, liver, and pancreatic histopathology were determined. Body weight and food intake were significantly reduced by PGX(®) vs. inulin and cellulose. Serum insulin in fasted and non-fasted states was significantly reduced by PGX(®) as was non-fasted blood glucose. Insulin resistance, measured as a HOMA score, was significantly reduced by PGX(®) in weeks 5 through 8 as well as terminal OGTT scores in fed and fasted states. Serum total cholesterol was also significantly reduced by PGX(®). PGX(®) significantly reduced histological kidney and hepatic damage in addition to reduced hepatic steatosis and cholestasis. A greater mass of pancreatic β-cells was found in the PGX(®) group. PGX(®) therefore may be a useful dietary additive in the control of the development of the early development of the metabolic syndrome.

Dyslipidemia is abnormalities of lipid and lipoprotein metabolism. Most dyslipidemias are hyperlipidemias; that is an abnormally high level of lipids and/or lipoproteins in the blood. Lipid and lipoprotein abnormalities are common in the general population, and are regarded as a modifiable risk factor for cardiovascular disease due to their influence on atherosclerosis. Primary dyslipidemia is usually due to genetic causes, while secondary dyslipidemia arises due to other underlying causes such as diabetes mellitus. Thus, dyslipidemia is an important factor in the development of atherosclerosis and cardiovascular diseases therefore, it is important to diagnose it in time. This review focuses on the modern methods of diagnosis of dyslipidemia.

Esterification of sterols, fatty acids and other alcohols into biologically inert forms conserves lipid resources for many cellular functions. Paradoxically, the accumulation of neutral lipids such as cholesteryl ester or triglyceride, is linked to several major disease pathologies. In a remarkable example of genetic expansion, there are at least eleven acyltransferase reactions that lead to neutral lipid production. In this review, we speculate that the complexity and apparent redundancy of neutral lipid synthesis may actually hasten rather than impede the development of novel, isoform-specific, therapeutic interventions for acne, type 2 diabetes, obesity, hyperlipidemia, fatty liver disease, and atherosclerosis.

This article examines the progression of bariatric surgery since its creation more than 60 years ago with a focus on the effect of surgery on weight loss, comorbidity reduction, and safety. The success has been remarkable. It is possible to cure severe obesity, type 2 diabetes, and hyperlipidemia in addition to the many other manifestations of the metabolic syndrome with remarkable safety. Equally important are the opportunities for research afforded by the surgery and its outcomes. Until better treatments become available, bariatric surgery is the therapy of choice for patients with morbid obesity for weight control and comorbidity improvement. Copyright © 2016 Elsevier Inc.

Niacin is a form of vitamin B3 which is used for the medical treatment of hyperlipidemia and niacin deficiency. However, within the last few years, it is being advertised on the Internet as a quick way to detoxify the human body in an attempt to evade urine drug tests. This claim is without any medical or scientific evidence and as a result, many cases have been reported where young adults have ended up with niacin toxicity. In this case report, we discuss a rare presentation of niacin toxicity and the effects Internet has had on the healthcare being practised by both the physicians and the patients themselves.

Lycopene is a kind of carotenoid, with a strong capacity of antioxidation and regulating the bloodlipid. There has been some evidence that lycopene has protective effects on the central nervous system, but few studies have rigorously explored the role of neurotransmitters in it. Therefore, the present study was designed to investigate the effects of several neurotransmitters as lycopene exerts anti-injury effects induced by hyperlipidemia. Eighty adult SD rats, half male and half female, were randomly divided into eight groups on the basis of serum total cholesterol (TC) levels and body weight. There was a control group containing rats fed a standard laboratory rodent chow diet (CD); a hypercholesterolemic diet (rat chow supplemented with 4% cholesterol, 1% cholic acid and 0.5% thiouracil - this is also called a CCT diet) group; a positive group (CCT + F) fed CCT, supplemented with 10 mg·kg·bw - 1 ·d - 1 fluvastatin sodium by gastric perfusion; and lycopene groups at five dose levels (CCT + LYCO) fed with CCT and supplied lycopene at doses of 5, 25, 45, 65, and 85 mg·kg·bw - 1 ·d - 1 . The levels of TC, triglyceride (TG), low-density lipoprotein cholesterol (LDL-C), high density lipoprotein cholesterol (HDL-C), interleukin-1 (IL-1), tumor necrosis factor alpha (TNF-α), oxidized low density lipoprotein (ox-LDL), low-density lipoprotein receptor (LDLR), nerve growth factor (NGF), glutamic acid (Glu), Gamma aminobutyric acid (GABA), dopamine (DA), 5-hydroxytryptamine (5-HT), N-methyl-D-aspartate (NMDA1R), GABA A , 5-HT 1 , D 1 , and apoptosis-related proteins Caspase3, bax, and bcl-2 were measured after the experiment. Nissl staining was adopted to observe the morphological changes in neurons. At the end of the experiment, the levels of TC, TG, LDL-C, IL-1, TNF-α, and ox-LDL in the serum and brain as well as the content of Glu, DA, NMDA, and D 1 in the brain of rats in the CCT group were higher than those in the control group (P<0.05); the levels of LDLR, NGF, GABA, 5-HT, GABA A , 5-HT 1 , and neuron quantities in the hippocampal CA1 and CA3 areas were lower than those in the control group (P<0.05). Compared to the CCT group, levels of TC, TG, LDL-C, IL-1, TNF-α, and ox-LDL in the serum and brain, as well as the content of Glu, DA and the expression of pro-apoptotic Caspase3 in the brain decreased in the rats with lycopene (25 mg to 85 mg) added to the diet (P<0.05); the levels of LDLR, NGF, GABA, 5-HT, GABA A , and 5-HT 1 as well as the expression of anti-apoptotic bcl-2 and the neuron quantity in hippocampal CA1 and CA3 areas increased (P<0.05); further, the hippocampal cells were closely arranged. Lycopene dose was negatively correlated with the levels of TC, TG, and LDL-C in the serum and brain as well as levels of IL-1, TNF-α, ox-LDL, Glu/GABA, NMDA1R, and Caspase3 (P<0.05); it was positively correlated with the levels of LDLR, NGF, 5-HT, 5-HT 1 , GABA A , bcl-2, and the neuron quantity in hippocampal CA1 and CA3 areas (P<0.05). Lycopene exerts anti-injury effects in the brain as-induced by hyperlipidemia. It can inhibit the elevation of serum TC, TG, and LDL-C in rats with hyperlipidemia while indirectly affecting the levels of TC, TG, and LDL-C in the brain, leading to a reduction in ox-LDL, IL-1, and TNF-α in the brain. This inhibits the release of Glu, which weakens nerve toxicity and downregulates pro-apoptotic Caspase3. Lycopene also plays an anti-injury role by promoting the release of the inhibitory neurotransmitter GABA and 5-HT, which enhances the protective effect, and by upregulating the anti-apoptotic bcl-2.

Cardiovascular and metabolic risks associated with PCOS.

PubMed

Cobin, Rhoda H

2013-04-01

Polycystic ovary syndrome, the most common endocrine disorder of reproductive age women, is often associated with insulin resistance and associated disorders. The frequency of type 2 diabetes, hyperlipidemia, cardiac risk markers, structural vascular disease, and clinical disease events are increased in this population of women. PCOS, however, represents a broad spectrum of clinical presentations, as defined by different criteria proposed in Europe and the United States. The role of insulin resistance and hence the risk of cardiometabolic disorders may in part be determined by the definition of PCOS used. Epidemiologic studies and clinical trials support the need to identify women with PCOS to determine their risk of cardiometabolic disorders to prevent and/or treat their serious consequences.

Other Risks/Possible Benefits of Obesity.

Obesity is not a cosmetic or social issue; it is an animal health issue. The metabolic effects of obesity on insulin resistance and development of hyperlipidemia and the mechanical stress excess weight places on the musculoskeletal system are well established in the literature. Additional health risks from obesity, such as fatty accumulation in the liver, intestinal bacterial dysbiosis, and changes to renal architecture, are less well understood, but have been demonstrated to occur clinically in obese animals and may lead to deleterious long-term health effects. Keeping dogs and cats lean lowers their risk for development of certain diseases and leads to a longer and better quality of life. Copyright © 2016 Elsevier Inc. All rights reserved.

Overwork, stroke, and karoshi-death from overwork.

Ke, Der-Shin

2012-06-01

Karoshi, death from over-work, is usually the extreme result of acute cardiovascular events including stroke. Among 203 karoshi cases received worker compensation in Japan, sixty percent died of stroke. Karoshi is a term for social medicine originated form Japan. Literature reviews on karoshi found that long overtime at work, on duty in holidays, attending a new job with no family members around, and working at night shift are risk factors. Work stress increases secretion of catecholamines (epinephrine and norepinephrine) and cortisol which is associated with progression of atherosclerosis and increased risk of cardiovascular diseases and stroke. To avoid long working hours, stress management and treatment of hypertension, diabetes, and hyperlipidemia are key issues in preventing karoshi caused by stroke.

Initial insufficiency of the antioxidant system, disturbances of the platelet-vascular hemostasis, hyperlipidemia and dyslipoproteinemia enhanced. Preoperative changes due to stress reaction affected the course of early intraoperative period. It is necessary to apply individual schemes of stress-limiting preoperative preparation in IHD patients.

The use of statins may have unnatural effects. A 54-year-old woman was admitted to the hospital with an incidental finding of hypercalcemia (10.8 mg/dL). There was no disease other than hyperlipidemia, and the patient had been on a course of atorvastatin calcium 10 mg for 1.5 years. A workup investigation to diagnose the cause of hypercalcemia was completed. The investigation did not reveal any pathological diseases that may have caused the hypercalcemia. The hypercalcemia resolved after atorvastatin-calcium was stopped, and the patient developed hypercalcemia shortly after the initiation of the atorvastatin calcium. Here, we report a clinical case of recurrent hypercalcemia possibly induced by atorvastatin calcium administration.

A case of erythema multiforme associated with gemfibrozil monotherapy. A 46-year-old man with hyperlipidemia was treated with 600 mg gemfibrozil twice a day. On the fifth day of treatment, skin lesions consistent with erythema multiforme appeared. With the discontinuation of the treatment and start of a topical steroid treatment, the lesions recovered after 4 weeks. After 6 months, when gemfibrozil therapy was restarted, lesions reappeared on the fourth day of therapy. Lesions recovered again following the previous treatment strategies after 4 weeks. An objective casualty assessment suggests that erythema multiforme was probably related to gemfibrozil monotherapy. Patients starting gemfibrozil therapy should be warned about the occurrence of erythema multiforme in addition to previous reported and established side effects.

Significant survival prolongation in HIV-infected patients due to effective antiretroviral therapy is connected with increasing prevalence of chronic non-infective diseases in this population, among them chronic kidney disease. The pathogenesis of kidney disease in the setting of HIV includes conditions specific for HIV infection: direct effect of the virus, stage of immunodeficiency and drug toxicity. Chronic comorbidities, such as diabetes mellitus, hypertension, and hyperlipidemia, are additional significant risk factors of kidney disease. In HIV-infected individuals some distinct features of these conditions are observed, which are partly related to the virus and antiretroviral therapy. The article summarizes the effect of comorbidities on kidney function in HIV-infected persons.

Persea americana, commonly known as avocado, is traditionally consumed fruit which possesses body fat lowering capacity. Adiponectin plays an important role in regulating obesity. In this study, the effect of hydro-alcoholic fruit extract of P. americana (HAEPA) on the level of blood lipids, glutathione, lipid peroxidation products, adiponectin and peroxisome proliferator activated receptor (PPAR)-γ expressions was investigated in rats fed a high-fat diet (HFD). Male Sprague Dawley rats were divided into four groups: groups 1 and 2 were fed normal rat chow (5% fat) and groups 3 and 4 were fed HFD (23% fat) for a period of 14 weeks. In addition, groups 2 and 4 rats were administered orally with 100 mg/kg body weight of HAEPA from third week. After 14 weeks, rats were sacrificed, and serum/plasma levels of total cholesterol, phospholipids, triglyceride, high-density lipoprotein (HDL), low-density lipoprotein (LDL) and adiponectin were determined. The mRNA expression of adiponectin, PPAR-γ and protein expression of PPAR-γ were also evaluated. The body mass index (BMI), total fat pad mass and adiposity index were significantly decreased in HAEPA co-administered rats than in HFD-fed rats. The levels of LDL and lipid peroxides were significantly higher in HFD group than in HFD+HAEPA group. Levels of reduced glutathione, adiponectin, mRNA expression of adiponectin, PPAR-γ and protein expression of PPAR-γ were found to be increased in HFD+HAEPA group than in HFD group. The hypolipidemic effect of HAEPA is also evidenced by the histological observations in liver, heart and adipose tissue. The results indicate that HAEPA exhibits hypolipidemic activity probably by increasing the mRNA expression of adiponectin and PPAR-γ, which reduce the risk of hyperlipidemia and obesity.

Our study aimed to explore associations between metabolic control, oxidative stress and coenzyme Q10 (CoQ10) in relation to diabetes complications in a representative population of type 2 diabetes. A geographic cohort of 156 subjects was recruited. Serum concentrations of CoQ10 and vitamin E were measured by HPLC. ROS was determined by free oxygen radicals testing (FORT). Glutaredoxin (Grx) activity, oxidized LDL cholesterol (oxLDLc), high sensitive CRP (hsCRP), HbA1c, urine albumin, serum creatinine, serum cystatin C, and plasma lipids were assayed with routine laboratory protocols. Serum CoQ10 was higher than in nondiabetics. HbA1c, fP-glucose, hyperlipidemia, inflammation (hsCRP), and increased BMI were associated with signs of oxidative stress as increased levels of FORT, Grx activity and/or increased levels of oxLDLc Oxidative stress was found to be strongly correlated with prevalence of cardiovascular disease (CVD) and peripheral sensory neuropathy (PSN). In both gender groups there were positive correlations between CoQ10 and oxLDLc, and between BMI and the ratio CoQ10/chol. Grx activity was inversely correlated to oxLDLc and CoQ10. Women with CVD and PSN had higher waist index, oxLDLc, and FORT levels compared to men but lower CoQ10 levels. Men had worse kidney function and lower vitamin E. Multiple regression analysis showed increased levels of CoQ10 to be significantly correlated with increased levels of cholesterol, triglycerides, vitamin E, fB-glucose and BMI. Hyperlipidemia, hyperglycemia and inflammation were associated with oxidative stress, which was correlated to the prevalence of diabetes complications. CoQ10 was increased in response to oxidative stress. There were gender differences in the risk factors associated with diabetes complications. Copyright © 2015 Elsevier Inc. All rights reserved.

Background Central to the pathology of coronary heart disease is the accumulation of lipids, cholesterol and triglycerides, within the intima of arterial blood vessels. The search for drugs to treat dislipidemia, remains a major pharmaceutical focus. In this study, we evaluated the hypolipidemic properties of the essential oil from Chios mastic gum (MGO). Methodology/Principal Findings The hypolipidemic effect of MGO was investigated in naïve as well as in rats susceptible to detergent-induced hyperlipidemia. Serum cholesterol and triglycerides were determined using commercial kits. HMG-CoA (3-hydroxy-3-methylglutaryl coenzyme A) reductase activity was measured in HepG2 cell extracts using a radioactive assay; cellular cholesterol and cholesterol esters were assessed using gas chromatography. MGO administration into naïve rats resulted in a dose-dependent reduction in the constitutive synthesis of serum cholesterol and triglycerides. In hyperlipidemic rats, MGO treatment had also a strong hypolipidemic effect. By testing various components of MGO, we show for the first time that the hypolipidemic action is associated with camphene. Administration of camphene at a dose of 30 µg/gr of body weight in hyperlipidemic rats resulted in a 54.5% reduction of total cholesterol (p<0.001), 54% of Low Density Lipoprotein (LDL)-cholesterol (p<0.001) and 34.5% of triglycerides (p<0.001). Treatment of HepG2 cells with camphene led to a decrease in cellular cholesterol content to the same extend as mevinolin, a known HMG-CoA reductase inhibitor. The hypolipidemic action of camphene is independent of HMG-CoA reductase activity, suggesting that its hypocholesterolemic and hypotriglyceridemic effects are associated with a mechanism of action different than that of statins. Conclusions Given the critical role that the control of hyperlipidemia plays in cardiovascular disease, the results of our study provide insights into the use of camphene as an alternative lipid lowering agent and merits further evaluation.

Patients with mutations in the proprotein convertase subtilisin/kexin type 9 (PCSK9) gene have hypercholesterolemia and are at high risk of adverse cardiovascular events. We aimed to stably express the pathological human D374Y gain-of-function mutant form of PCSK9 (PCSK9(DY)) in adult wild-type mice to generate a hyperlipidemic and proatherogenic animal model, achieved with a single systemic injection with adeno-associated virus (AAV). We constructed an AAV-based vector to support targeted transfer of the PCSK9(DY) gene to liver. After injection with 3.5×10(10) viral particles, mice in the C57BL/6J, 129/SvPasCrlf, or FVB/NCrl backgrounds developed long-term hyperlipidemia with a strong increase in serum low-density lipoprotein. Macroscopic and histological analysis showed atherosclerotic lesions in the aortas of AAV-PCSK9(DY) mice fed a high-fat-diet. Advanced lesions in these high-fat-diet-fed mice also showed evidence of macrophage infiltration and fibrous cap formation. Hepatic AAV-PCSK9(DY) infection did not result in liver damage or signs of immunologic response. We further tested the use of AAV-PCSK9(DY) to study potential genetic interaction with the ApoE gene. Histological analysis of ApoE(-/-) AAV-PCSK9(DY) mice showed a synergistic response to ApoE deficiency, with aortic lesions twice as extensive in ApoE(-/-) AAV-PCSK9(DY)-transexpressing mice as in ApoE(-/-) AAV-Luc controls without altering serum cholesterol levels. Single intravenous AAV-PCSK9(DY) injection is a fast, easy, and cost-effective approach, resulting in rapid and long-term sustained hyperlipidemia and atherosclerosis. We demonstrate as a proof of concept the synergy between PCSK9(DY) gain-of-function and ApoE deficiency. This methodology could allow testing of the genetic interaction of several mutations without the need for complex and time-consuming backcrosses. © 2014 American Heart Association, Inc.

The patterns and determinants of saxagliptin use among patients with type 2 diabetes mellitus (T2DM) are unknown in real-world settings. We compared the characteristics of T2DM patients who were new initiators of saxagliptin to those who were new initiators of non-dipeptidyl peptidase-4 (DPP-4) inhibitor oral anti-diabetic drugs (OADs) and identified factors associated with saxagliptin use. We conducted a cross-sectional study within the Clinical Practice Research Datalink (CPRD), The Health Improvement Network (THIN), US Medicare, and the HealthCore Integrated Research Database (HIRD(SM)) across the first 36 months of saxagliptin availability (29 months for US Medicare). Patients were included if they were: 1) ≥18 years old, 2) newly prescribed saxagliptin or a non-DPP-4 inhibitor OAD, and 3) enrolled in their respective database for 180 days. For each saxagliptin initiator, we randomly selected up to ten non-DPP-4 inhibitor OAD initiators matched on age, sex, and geographic region. Conditional logistic regression was used to identify determinants of saxagliptin use. We identified 64,079 saxagliptin initiators (CPRD: 1,962; THIN: 2,084; US Medicare: 51,976; HIRD(SM): 8,057) and 610,660 non-DPP-4 inhibitor OAD initiators (CPRD: 19,484; THIN: 19,936; US Medicare: 493,432; HIRD(SM): 77,808). Across all four data sources, prior OAD use, hypertension, and hyperlipidemia were associated with saxagliptin use. Saxagliptin initiation was also associated with hemoglobin A1c results >8% within the UK data sources, and a greater number of hemoglobin A1c measurements in the US data sources. In these UK and US data sources, initiation of saxagliptin was associated with prior poor glycemic control, prior OAD use, and diagnoses of hypertension and hyperlipidemia.

Renin-angiotensin system and adenosine monophosphate-activated protein kinase signaling pathway both play important roles in carcinogenesis, but the interplay of renin-angiotensin system and adenosine monophosphate-activated protein kinase in carcinogenesis is not clear. In this study, we researched the interaction of renin-angiotensin system and adenosine monophosphate-activated protein kinase in renal carcinogenesis of uninephrectomized rats. A total of 96 rats were stratified into four groups: sham, uninephrectomized, and uninephrectomized treated with angiotensin-converting enzyme inhibitor or angiotensin receptor blocker. Renal adenosine monophosphate-activated protein kinase and its downstream molecule acetyl coenzyme A carboxylase were detected by immunohistochemistry and western blot at 10 months after uninephrectomy. Meanwhile, we examined renal carcinogenesis by histological transformation and expressions of Ki67 and mutant p53. During the study, fasting lipid profiles were detected dynamically at 3, 6, 8, and 10 months. The results indicated that adenosine monophosphate-activated protein kinase expression in uninephrectomized rats showed 36.8% reduction by immunohistochemistry and 89.73% reduction by western blot. Inversely, acetyl coenzyme A carboxylase expression increased 83.3% and 19.07% in parallel to hyperlipidemia at 6, 8, and 10 months. The histopathology of carcinogenesis in remnant kidneys was manifested by atypical proliferation and carcinoma in situ, as well as increased expressions of Ki67 and mutant p53. Intervention with angiotensin-converting enzyme inhibitor or angiotensin receptor blocker significantly prevented the inhibition of adenosine monophosphate-activated protein kinase signaling pathway and renal carcinogenesis in uninephrectomized rats. In conclusion, the novel findings suggest that uninephrectomy-induced disturbance in adenosine monophosphate-activated protein kinase signaling pathway resulted in hyperlipidemia and carcinogenesis in tubular epithelial cells, which may be largely attenuated by renin-angiotensin system blockade, implying the interaction of renin-angiotensin system and adenosine monophosphate-activated protein kinase signaling pathway in renal carcinogenesis of uninephrectomized rats.

Low testosterone levels (low T) increase the cardiovascular (CV) risk of men with erectile dysfunction (ED). T levels associated with a higher CV risk are unknown. To determine the prevalence of CV risk factors associated with low T as defined by European Guidelines and their contribution to low T, overall and at different ages. Multicenter, cross-sectional, observational study conducted in Spain among men with ED aged ≥ 18 years visiting Urology/Andrology offices for sexual dysfunction. Anthropometric, clinical, and laboratory data, including total T (TT) values, were collected for 1,278 men. Risk factors were assessed in men with TT ≤ 8, 8-12, and ≥ 12 nmol/L, and two-group comparisons were made. Bivariate and multivariate logistic regression analyses were performed to calculate odds ratios for low T after adjusting for possible confounding factors. Mean age (standard deviation) was 58.0 (9.2) years. Age and prevalence of CV risk factors was similar in men with TT ≤ 8 nmol/L or 8-12 nmol/L and significantly higher than in men with TT >12 nmol/L. Low T was therefore considered as TT ≤ 12 nmol/L, with a prevalence of 33.3%. Obesity, hypertension, hyperlipidemia, and severe ED were the variables most strongly associated with low T: obesity in middle-aged men; hyperlipidemia, and hypertension in older men. Severe ED was a risk factor in both groups. Hypolipidemic therapy had the greater effect in young men. Multivariate analysis showed that severe ED and obesity were the strongest predictors of low T. T levels associated with increased CV risk could go as high as 12 nmol/L in men with ED, with distribution of risk factors showing differences according to age. Obesity and severe ED are the best predictors of low T-related CV risk. © 2014 International Society for Sexual Medicine.

Statins are the most commonly prescribed drugs to reduce cardiometabolic risk. Besides the well-known efficacy of such compounds in both preventing and treating cardiometabolic disorders, some patients experience statin-induced side effects. We hypothesize that the use of natural bergamot-derived polyphenols may allow patients undergoing statin treatment to reduce effective doses while achieving target lipid values. The aim of the present study is to investigate the occurrence of an enhanced effect of bergamot-derived polyphenolic fraction (BPF) on rosuvastatin-induced hypolipidemic and vasoprotective response in patients with mixed hyperlipidemia. A prospective, open-label, parallel group, placebo-controlled study on 77 patients with elevated serum LDL-C and triglycerides was designed. Patients were randomly assigned to a control group receiving placebo (n=15), two groups receiving orally administered rosuvastatin (10 and 20mg/daily for 30 days; n=16 for each group), a group receiving BPF alone orally (1000 mg/daily for 30 days; n=15) and a group receiving BPF (1000 mg/daily given orally) plus rosuvastatin (10mg/daily for 30 days; n=15). Both doses of rosuvastatin and BPF reduced total cholesterol, LDL-C, the LDL-C/HDL-C ratio and urinary mevalonate in hyperlipidemic patients, compared to control group. The cholesterol lowering effect was accompanied by reductions of malondialdehyde, oxyLDL receptor LOX-1 and phosphoPKB, which are all biomarkers of oxidative vascular damage, in peripheral polymorphonuclear cells. Addition of BPF to rosuvastatin significantly enhanced rosuvastatin-induced effect on serum lipemic profile compared to rosuvastatin alone. This lipid-lowering effect was associated with significant reductions of biomarkers used for detecting oxidative vascular damage, suggesting a multi-action enhanced potential for BPF in patients on statin therapy. © 2013.

The mixture of Hongqu and gypenosides (HG) is composed of Fermentum Rubrum (Hongqu, in Chinese) and total saponins of Gynostemma pentaphyllum (Thunb.) Makino (Jiaogulan, in Chinese) in a 3.6:1 weight ratio. Both Hongqu and Jiaogulan are considered valuable traditional Chinese medicines (TCMs); they have been commonly used in China for the treatment of hyperlipidemia and related diseases for centuries. The aim of the current study was assess the anti-atherosclerotic effect of HG. Sixty-four Wistar rats were randomly divided into eight groups: normal, model, positive control (simvastatin, 1 mg/kg), Hongqu-treated (72 mg/kg), gypenoside (total saponin)-treated (20 mg/kg), and three doses HG-treated (50, 100, and 200 mg/kg). All of the rats were fed a basal diet. Additionally, the model group rats were intragastrically administered a high-fat emulsion and intraperitoneally injected with vitamin D 3 . The serum lipid profiles, oxidative stress, inflammatory cytokine, and hepatic antioxidant levels were then determined. Furthermore, the liver histopathology and arterial tissue were analyzed, and the expression of hyperlipidemia- and atherosclerosis (AS)-related genes was measured using reverse transcription-polymerase chain reaction. The AS rat model was established after 80 days. Compared to the model group, the HG-treated groups showed an obvious improvement in the serum lipid profiles, oxidative stress, and inflammatory cytokine levels, and showed markedly increased hepatic total antioxidant capacity. Moreover, the expression of genes related to lipid synthesis and inflammation reduced and that of the genes related to lipid oxidation increased in the liver and arterial tissue, which also reflected an improved health condition. the anti-atherosclerotic effects of HG were superior to those of simvastatin, Hongqu, and the gypenosides. Therefore, HG may be a useful anti-atherosclerotic TCM preparation. Copyright © 2017. Published by Elsevier Taiwan LLC.

Previous studies have shown that inactivation of the group 1B phospholipase A2 (Pla2g1b) suppresses diet-induced obesity, hyperglycemia, insulin resistance, and hyperlipidemia in C57BL/6 mice. A possible influence of Pla2g1b inactivation on atherosclerosis has not been addressed previously. The current study utilized LDL receptor-deficient (Ldlr(-/-)) mice with plasma lipid levels and distribution similar to hyperlipidemic human subjects as a preclinical animal model to test the effectiveness of Pla2g1b inactivation on atherosclerosis. The Pla2g1b(+/+)Ldlr(-/-) and Pla2g1b(-/-)Ldlr(-/-) mice were fed a low fat chow diet or a hypercaloric diet with 58.5 kcal% fat and 25 kcal% sucrose for 10 weeks. Minimal differences were observed between Pla2g1b(+/+)Ldlr(-/-) and Pla2g1b(-/-)Ldlr(-/-) mice when the animals were maintained on the low fat chow diet. However, when the animals were maintained on the hypercaloric diet, the Pla2g1(+/+)Ldlr(-/-) mice showed the expected body weight gain but the Pla2g1b(-/-)Ldlr(-/-) mice were resistant to diet-induced body weight gain. The Pla2g1b(-/-)Ldlr(-/-) mice also displayed lower fasting glucose, insulin, and plasma lipid levels compared to the Pla2g1b(+/+)Ldlr(-/-) mice, which displayed robust hyperglycemia, hyperinsulinemia, and hyperlipidemia in response to the hypercaloric diet. Importantly, atherosclerotic lesions in the aortic roots were also reduced 7-fold in the Pla2g1b(-/-)Ldlr(-/-) mice. The effectiveness of Pla2g1b inactivation to suppress diet-induced body weight gain and reduce diabetes and atherosclerosis in LDL receptor-deficient mice suggests that pharmacological inhibition of Pla2g1b may be a viable strategy to decrease diet-induced obesity and the risk of diabetes and atherosclerosis in humans.

We aimed to examine the effect of increased physician awareness on the rate and determinants of influenza and pneumococcal vaccinations in diabetic patients. Diabetic patients (n = 5682, mean [SD] age: 57.3 [11.6] years, 57% female) were enrolled by 44 physicians between Sept 2010 and Jan 2011. The physicians were initially questioned regarding vaccination practices, and then, they attended a training program. During the last five years, the physicians recommended influenza and pneumococcal vaccinations to 87.9% and 83.4% of the patients, respectively; however; only 27% of the patients received the influenza and 9.8% received the pneumococcal vaccines. One year after the training, the vaccination rates increased to 63.3% and 40.7%, respectively. The logistic regression models revealed that variables which increased the likelihood of having been vaccinated against influenza were: longer duration of diabetes, presence of hyperlipidemia and more use of concomitant medications whereas more use of anti-hyperglycemic medications was associated with increased odds of vaccination. On the other hand, older age, longer duration of diabetes and presence of a cardiovascular disease were variables which decreased the likelihood of having been vaccinated against pneumococcal disease during the past five years. However, during the study period, variables which decreased the odds of having been vaccinated included: older age and anti-hyperglycemic medications for influenza, and presence of hyperlipidemia and a family history of hypertension for pneumococcal disease. While variables which increased the likelihood of vaccination in the same period were: increased number of co-morbidities for influenza, and family history of diabetes for pneumococcal disease. We conclude that increased awareness of physicians may help improve vaccination rates against influenza and pneumococcal disease. However, diabetic patients with more severe health conditions are less likely to having been vaccinated. More structural/systematic vaccination programs are needed to increase the vaccination rates in patients with diabetes.

Insulin therapy and oral antidiabetic agents/drugs used in the treatment of diabetes mellitus have not sufficiently proven to control hyperlipidemia, which is commonly associated with the diabetes mellitus. Again the hopes that traditional medicine and natural plants seem to trigger researchers in this area is yet to be discovered. This research was designed to compare the biochemical effects of some medicinal plants in alloxan-induced diabetic male Wistar rats using named plants that are best at lowering blood glucose and hyperlipidemia and ameliorating other complications of diabetes mellitus by methods of combined therapy. The results obtained showed 82% decrease in blood glucose concentration after the 10th hour to the fortieth hour. There was significant increase P < 0.05 in the superoxide dismutase activity of the test group administered 100 mg/kg of A. Occidentale. There was no significant difference P > 0.05 recorded in the glutathione peroxidase activity of E. globulus (100 mg/kg) when compared to the test groups of P. guajava (250 mg/kg) and X. aethiopica (250 mg/kg). Catalase activity showed significant increase P < 0.05 in the catalase activity, compared to test groups. While at P > 0.05, there was no significant difference seen between test group and treated groups. Meanwhile, degree of significance was observed in other parameters analysed. The biochemical analysis conducted in this study showed positive result, attesting to facts from previous works. Though these individual plants extracts exhibited significant increase in amelorating diabetes complication and blood glucose control compared to glibenclamide, a synthetic antidiabetic drug. Greater performance was observed in the synergy groups. Therefore, a poly/combined formulation of these plants extracts yielded significant result as well as resolving some other complications associated with diabetics.

BSN723T Prevents Atherosclerosis and Weight Gain in ApoE Knockout Mice Fed a Western Diet.

This study tests the hypothesis that BSN723T can prevent the development of hyperlipidemia and atherosclerosis in ApoE -/- knockout mice fed a Western (high fat, high cholesterol, and high sucrose) diet. BSN723T is a combination drug therapy consisting of D-tagatose and dihydromyricetin (BSN723). D-tagatose has an antihyperglycemic effect in animal and human studies and shows promise as a treatment for type 2 diabetes and obesity. Many claims regarding BSN723's pharmacological activities have been made including anti-cancer, anti-diabetic, anti-hypertensive, anti-inflammatory, and anti-atherosclerotic effects. To our knowledge this is the first study that combines D-tagatose and BSN723 for the treatment of hyperlipidemia and the prevention of atherosclerosis. ApoE-deficient mice were randomized into five groups with equivalent mean body weights. The mice were given the following diets for 8 weeks: Group 1 - Standard diet; Group 2 - Western diet; Group 3 - Western diet formulated with D-tagatose; Group 4 - Western diet formulated with BSN723; Group 5 - Western diet formulated with BSN723T. Mice were measured for weight gain, tissue and organ weights, total serum cholesterol and triglycerides and formation of atherosclerosis. The addition of D-tagatose, either alone or in combination with BSN723, prevented the increase in adipose tissue and weight gain brought on by the Western diet. Both D-tagatose and BSN723 alone reduced total cholesterol and the formation of atherosclerosis in the aorta compared to mice on the Western diet. Addition of BSN723 to D-tagatose (BSN723T) did not increase efficacy in prevention of increases in cholesterol or atherosclerosis compared to D-tagatose alone. Addition of either D-tagatose or BSN723 alone to a Western diet prevented weight gain, increases in total serum cholesterol and triglycerides, and the formation of atherosclerosis. However, there was no additive or synergistic effect on the measured parameters with the combination BSN723T treatment.

Background. Individuals infected with human immunodeficiency virus (HIV) are at increased risk for cardiovascular disease (CVD) events compared with uninfected persons. However, little is known about HIV provider practices regarding aspirin (ASA) for primary prevention of CVD. Methods. A cross-sectional study was conducted among patients attending the University of Alabama at Birmingham 1917 HIV Clinic during 2010 to determine the proportion receiving ASA for primary prevention of CVD and identify factors associated with ASA prescription. Ten-year risk for CVD events was calculated for men aged 45–79 and women aged 55–79. The 2009 US Preventive Services Task Force (USPSTF) guidelines were used to determine those qualifying for primary CVD prevention. Results. Among 397 patients who qualified to receive ASA (mean age, 52.2 years, 94% male, 36% African American), only 66 (17%) were prescribed ASA. In multivariable logistic regression analysis, diabetes mellitus (odds ratio [OR], 2.60; 95% confidence interval [CI], 1.28–5.27), hyperlipidemia (OR, 3.42; 95% CI, 1.55–7.56), and current smoking (OR, 1.87; 95% CI, 1.03–3.41) were significantly associated with ASA prescription. Odds of ASA prescription more than doubled for each additional CVD-related comorbidity present among hypertension, diabetes, hyperlipidemia, and smoking (OR, 2.13, 95% CI, 1.51–2.99). Conclusions. In this HIV-infected cohort, fewer than 1 in 5 patients in need received ASA for primary CVD prevention. Escalating likelihood of ASA prescription with increasing CVD-related comorbidity count suggests that providers may be influenced more by co-occurrence of these diagnoses than by USPSTF guidelines. In the absence of HIV-specific guidelines, interventions to improve HIV provider awareness of and adherence to existing general population guidelines on CVD risk reduction are needed. PMID:22942209

Thrombolytic therapy is recommended for patients with acute ST-segment elevation myocardial infarction (STEMI) who cannot undergo primary percutaneous coronary intervention within the first 120 min. The aim of this study wasz to demonstrate the value of CHA₂DS₂-VASc and CHA₂DS₂-VASc-HS scores in predicting failed reperfusion in STEMI patients treated with thrombolytic therapy. A total of 537 consecutive patients were enrolled in the study; 139 had failed thrombolysis while the remaining 398 fulfilled the criteria for successful thrombolysis. Thrombolysis failure was defined with the lack of symptom relief, < 50% ST resolution-related electrocardiography within 90 min from initiation of the thrombolytic therapy, presence of hemodynamic or electrical instability or in-hospital mortality. CHA₂DS₂-VASc and CHA₂DS₂-VASc-HS scores, which incorporate hyperlipidemia, smoking, switches between female and male gender, were previously shown to be markers of the severity of coronary artery disease (CAD). History of hypertension, diabetes mellitus, hyperlipidemia, heart failure, smoking, and CAD were significantly common in failed reperfusion patients (for all; p < 0.05). For prediction of failed reperfusion, the cut-off value of CHA₂DS₂-VASc score was ≥ 2 with a sensitivity of 80.90% and a specificity of 41.01% (area under curve [AUC] 0.660; 95% confidence interval [CI] 0.618-0.700; p < 0.001) and the cut-off value of CHA₂DS₂-VASc-HS score was ≥ 3 with a sensitivity of 76.13% and a specificity of 67.63% (AUC 0.764; 95% CI 0.725-0.799; p < 0.001). The CHA₂DS₂-VASc-HS score was found to be statistically and significantly better than CHA₂DS₂-VASc score to predict failed reperfusion (p < 0.001). The findings suggest that the CHA₂DS₂-VASc and especially CHA₂DS₂-VASc-HS scores could be considered as predictors of risk of failed reperfusion in STEMI patients.

Serum sialic acid levels are positively correlated with coronary artery disease and inflammation. Although sialic acid is a non-specific marker, it is considered sensitive likely due to its influence in sialylation of glycoprotein structures all over the body. We hypothesized that dietary supplementation with N-acetylneuraminic acid (Neu5Ac), a type of sialic acid, will have profound effects on high fat diet- (HFD-) induced inflammation and oxidative stress in view of the widespread incorporation of sialic acid into glycoprotein structures in the body. HFD-fed rats with or without simvastatin or Neu5Ac (50 and 400 mg/kg/day) were followed up for 12 weeks. Lipid profiles, and markers of inflammation (C-reactive protein, interleukin-6, and tumor necrosis factor alpha), insulin resistance (serum insulin and adiponectin, oral glucose tolerance test and homeostatic model of insulin resistance) and oxidative stress (total antioxidant status and thiobarbituric acid reactive species) in the serum and liver were determined, while mRNA levels of hepatic antioxidant and inflammation genes were also quantified. Serum levels of alanine transaminase, aspartate transaminase, alkaline phosphatase, urea, creatinine and uric acid were also assessed. HFD feeding caused hyperlipidemia and insulin resistance, and worsened liver and kidney functions. HFD feeding also potentiated inflammation and oxidative stress, partly through modulation of hepatic gene expression, while Neu5Ac especially at higher doses and simvastatin attenuated HFD-induced changes, although Neu5Ac showed better outcomes. Based on the present results, we surmised that Neu5Ac can prevent HFD-induced inflammation and oxidative stress, and may in fact be useful in the prevention of hyperlipidemia-associated inflammation and oxidative stress. However, the translational implications of these findings can only be determined after long-term effects are established. Hence, the use of Neu5Ac on obesity-related diseases requires additional attention.

Combined hyperlipidemia (CHL) is a common disorder of lipidmetabolism that leads to an increased risk of cardiovascular disease. Thelipid profile of CHL is characterised by high levels of atherogeniclipoproteins and low levels of high-density-lipoprotein-cholesterol.Apolipoprotein (APO) A5 is a newly discovered gene involved in lipidmetabolism located within 30kbp of the APOA1/C3/A4 gene cluster. Previousstudies have indicated that sequence variants in this cluster areassociated with increased plasma lipid levels. To establish whethervariation at the APOA5 gene contributes to the transmission of CHL, weperformed linkage and linkage disequilibrium (LD) tests on a large cohortof families (n=128) with familial CHL (FCHL). The linkage datamore » producedevidence for linkage of the APOA1/C3/A4/A5 genomic interval to FCHL (NPL= 1.7, P = 0.042). The LD studies substantiated these data. Twoindependent rare alleles, APOA5c.56G and APOC3c.386G of this gene clusterwere over-transmitted in FCHL (P = 0.004 and 0.007, respectively), andthis was associated with a reduced transmission of the most commonAPOA1/C3/A4/A5 haplotype (frequency 0.4425) to affected subjects (P =0.013). The APOA5c.56G allele was associated with increased plasmatriglyceride levels in FCHL probands, whereas the second, andindependent, APOC3c.386G allele was associated with increased plasmatriglyceride levels in FCHL pedigree founders. Thus, this allele (or anallele in LD) may mark a quantitative trait associated with FCHL, as wellas representing a disease susceptibility locus for the condition. Thisstudy establishes that sequence variation in the APOA1/C3/A4/A5 genecluster contributes to the transmission of FCHL in a substantialproportion of affected families, and that these sequence variants mayalso contribute to the lipid abnormalities of the metabolic syndrome,which is present in up to 40 percent of persons with cardiovasculardisease.« less

Beneficial effects of cytokine induced hyperlipidemia.

Infection, inflammation and trauma induce marked changes in the plasma levels of a wide variety of proteins (acute phase response), and these changes are mediated by cytokines. The acute phase response is thought to be beneficial to the host. The host's response to injury also results in dramatic alterations in lipid metabolism and circulating lipoprotein levels which are mediated by cytokines. A large number of cytokines including TNF, the interleukins, and the interferons increase serum triglyceride levels. This rapid increase (1-2 h) is predominantly due to an increase in hepatic VLDL secretion while the late increase may be due to a variety of factors including increased hepatic production of VLDL or delayed clearance secondary to a decrease in lipoprotein lipase activity and/or apolipoprotein E levels on VLDL. In animals other than primates, cytokines also increase serum cholesterol levels, most likely by increasing hepatic cholesterol. Cytokines increase hepatic cholesterol synthesis by stimulating HMG CoA reductase gene expression and decrease hepatic cholesterol catabolism by inhibiting cholesterol 7 alpha-hydroxylase, the key enzyme in bile acid synthesis. Injury and/or cytokines also decrease HDL cholesterol levels and induce alterations in the composition of HDL. The content of SAA and apolipoprotein J increase, apolipoprotein A1 may decrease, and the cholesterol ester content decreases while free cholesterol increases. Additionally, key proteins involved in HDL metabolism are altered by cytokines; LCAT activity, hepatic lipase activity, and CETP levels decrease. These changes in lipid and lipoprotein metabolism may be beneficial in a number of ways including: lipoproteins competing with viruses for cellular receptors, apolipoproteins neutralizing viruses, lipoproteins binding and targeting parasites for destruction, apolipoproteins lysing parasites, redistribution of nutrients to cells involved in the immune response and/or tissue repair, and lipoproteins binding toxic agents and neutralizing their harmful effects. Thus, cytokines induce marked changes in lipid metabolism that lead to hyperlipidemia which represents part of the innate immune response and may be beneficial to the host.

Healthcare systems spend considerable proportions of their budgets on pharmaceutical treatment of hypertension, hyperlipidemia, and diabetes mellitus. From data on almost all residents of Austria, a country with mandatory health insurance and universal health coverage, we estimated potential cost savings by substituting prescribed medicines with the cheapest medicines that were of the same chemical substance and strength, and available during the same time. Data from 8.3 million persons (98.5 % of the total Austrian insured population) from 2009-2012 were analyzed. Real prescription costs for antihypertensive, lipid-lowering, and hypoglycemic medicines achievable by same-substance, same-strength drug substitution were computed for each active ingredient, and per gender and 1-year age category of patients. In 2012, health insurance providers spent 231.3 million, 77.8 million, and 91.9 million for antihypertensive, lipid-lowering, and diabetes medications, of which 52.2 million (22.6 %), 15.9 million (20.5 %), and 4.1 million (4.5 %), respectively, could have been saved by same-substance drug substitution. Highest potential savings were calculated for amlodipine (8.0 million, 65.4 %), simvastatin (12.2 million, 59.3 %), and metformin (2.4 million, 54.6 %), respectively. Higher savings for men than for women resulted from differing prescribed cumulative dosages and proportions of patients with co-payment waiver. Potential cost savings in antihypertensive and lipid-lowering drugs increased from 2009-2012. Our study highlights the cost-savings potential from arguably the most acceptable of interventions, simply switching to the cheapest available same-substance, same-strength product. In 2012, this strategy could have reduced costs for antihypertensive, lipid-lowering, and hypoglycemic treatment by up to 18.0 %.

Hyperlipidemia and increased degree of oxidative stress are among the important risk factors for Atherosclerosis in renal transplant recipients (RTR). The Medical treatment of hyperlipidemia in RTR because of drugs side effects has been problematic, therefore alternative methods such as using of Garlic as an effective material in cholesterol lowering and inhibition of LDL Oxidation has been noted. For evaluation of garlic effect on RTR, 50 renal transplant patients with stable renal function were selected and divided into 2 groups. They took one clove of garlic (1 gr) by chewing or swallowing for two months, after one month wash-out period, they took garlic by the other route. Results indicated that although lipid profile, BUN, Cr, serum levels of cyclosporine and diastolic blood pressure did not change, Systolic blood pressure decreased from 138.2 to 132.8 mmHg (p=0.001) and Malondialdehyde (MDA) decreased from 2.4 to 1.7 nmol/ml (p=0.009) by swallowing route, Cholesterol decreased from 205.1 to 195.3 mg/dl (p=0.03), triglyceride decreased from 195.7 to 174.8 mg/dl (p=0.008), MDA decreased from 2.5 to 1.6 nmol/ml (p=0.001), systolic blood pressure decreased from 137.5 to 129.8 mmHg (p=0.001), diastolic blood pressure decreased from 84.6 to 77.6 mmHg (p=0.001) and Cr decreased from 1.51 to 1.44 mg/dl (p=0.03) by chewing route too. However HDL, LDL and cyclosporine serum levels had no significant differences by both of swallowing and chewing routes. We conclude that undamaged garlic (swallowed) had no lowering effect on lipid level of serum. But Crushed garlic (chewed) reduces cholesterol, triglyceride, MDA and blood pressure. Additionally creatinine reduced without notable decrease in cyclosporine serum levels may be due to cyclosporine nephrotoxicity ameliorating effect of garlic.

To assess the associations between vascular and metabolic comorbidities and the prevalence of open-angle glaucoma (OAG) with low-teen and high-teen intraocular pressure (IOP) in Korea. Cross-sectional data from the Korean National Health and Nutrition Examination Survey from 2008 to 2012 were analysed. Participants diagnosed with OAG with normal IOP were further classified into low-teen IOP (IOP ≤ 15 mmHg) and high-teen IOP (15 mmHg < IOP ≤ 21 mmHg) groups. Using multiple logistic regression analyses, the associations between vascular and metabolic comorbidities and the prevalence of glaucoma were investigated for the low- and high-teen IOP groups. The prevalences of hypertension, hyperlipidemia, ischaemic heart disease, stroke and metabolic syndrome were significantly higher among subjects with low-teen OAG compared with normal subjects, while only the prevalences of hypertension and stroke were higher among subjects with high-teen OAG compared with normal subjects. In multivariate logistic regression models adjusted for confounding factors, low-teen OAG was significantly associated with hypertension (OR, 1.68; 95% CI, 1.30-2.18), hyperlipidemia (OR, 1.49; 95% CI, 1.07-2.08), ischaemic heart disease (OR, 1.83; 95% CI, 1.07-3.11), stroke (OR, 1.91; 95% CI, 1.12-3.25) and metabolic syndrome (OR, 1.46; 95% CI, 1.12-1.90). High-teen OAG was only associated with stroke (OR, 2.58; 95% CI, 1.20-5.53). Various vascular and metabolic comorbidities were significantly associated with low-teen OAG, but not with high-teen OAG. These data support the hypothesis that vascular factors play a more significant role in the pathogenesis of OAG with low-teen baseline IOP. © 2017 Acta Ophthalmologica Scandinavica Foundation.

Dietary supplements provide a novel population based health approach for treating hyperlipidemias. Red yeast rice is known to have lipid lowering effects. Combination of red yeast rice with various oils is taken by different population around the world. In this present work, we aimed to compare the effects of red yeast rice with different oil (coconut, rice bran and sunflower oil) supplementations on lipid levels and oxidative stress in rats fed on hypercholesterolemic diet. A Randomized controlled study was conducted on 28 male Sprague Dawley rats. It included 4 arms-Control arm (hypercholesterolemic diet), Test arm A (hypercholesterolemic diet +Red yeast rice + Rice bran oil), arm B (hypercholesterolemic diet +Red yeast rice + Coconut oil) and arm C (hypercholesterolemic diet +Red yeast rice + Sunflower oil). At the end of one month, serum cholesterol, triglycerides, MDA and paraoxonase was measured. The mean values of analytes between the different groups were compared using student 't-' test. The rats fed with red yeast rice and rice bran oil combination showed significantly lower levels of serum cholesterol, triglycerides and MDA when compared to the controls. The serum paraoxonase levels were significantly higher in this group when compared to the controls. The rats fed with red yeast rice and coconut oil combination showed significantly lower serum cholesterol and MDA levels when compared to the controls. The mean triglyceride and paraoxonase levels did not show any statistically significant difference from the controls. The rats on red yeast rice and sunflower oil combination did not show any statistically significant difference in the lipid levels and oxidative stress parameters. The food combination which had best outcome in preventing the development of hyperlipidemia and oxidative stress in rats fed with hypercholesterolemic diet was red yeast rice and rice bran oil. Combining red yeast rice with coconut oil and sunflower oil gave suboptimal benefits.

ISIS 301012 gene therapy for hypercholesterolemia: sense, antisense, or nonsense?

Ito, Matthew K

2007-10-01

To present an overview of antisense technology and to review and assess available literature on the chemistry, pharmacology, pharmacokinetics, drug interactions, preclinical and clinical studies, dosing, and adverse events of ISIS 301012 in the treatment of hyperlipidemia. PubMed database searches were conducted from 1966 to May 2007 using the search terms ISIS 301012, antisense, oligonucleotide, hypercholesterolemia, hyperlipidemia, and apolipoprotein B. Bibliographies of relevant review articles and information from the manufacturer were reviewed for additional references. Available English-language literature, including abstracts, preclinical, and clinical trials, review articles, and scientific presentations were examined. Apolipoprotein B is an important structural protein on the surface of atherogenic lipoproteins such as remnant very-low-density lipoprotein and low-density lipoprotein and facilitates the clearance of these particles from the circulation by binding to the low-density lipoprotein receptor. Overproduction of apolipoprotein B or reduced receptor-mediated clearance of lipoproteins leads to elevated serum cholesterol levels and premature atherosclerosis. ISIS 301012 is an antisense oligonucleotide that inhibits apolipoprotein B production by binding directly to and reducing the expression of apolipoprotein B messenger RNA. In a clinical trial, ISIS 301012 50-400 mg administered weekly via subcutaneous injection for 4 weeks reduced apolipoprotein B by 14.3-47.4% and low-density lipoprotein cholesterol by 5.9-40% at 55 days. The most frequent adverse event was injection-site erythema that resolved spontaneously. Studies are ongoing to further define the safety, efficacy, and pharmacokinetics of ISIS 301012 as add-on therapy in patients with heterozygous and homozygous familial hypercholesterolemia. No pharmacokinetic interactions have been demonstrated with ezetimibe and simvastatin. ISIS 301012 is the first agent to enter clinical trials utilizing an antisense mechanism for reducing the production of apolipoprotein B. Further studies are needed to verify its safety, efficacy, and position of therapy in the dyslipidemic patient.

To observe the effect of combining red yeast rice and Lactobacillus casei (L. casei) in lowering cholesterol in patients with primary hyperlipidemia, the later has also been shown to remove cholesterol in in vitro studies. A double-blind clinical trial was conducted to evaluate the cholesterol-lowering effect of the combination of red yeast rice and L. casei. Sixty patients with primary hyperlipidemia were recruited and randomized equally to either the treatment group (red yeast rice + L. casei) or the control group (red yeast rice + placebo). One red yeast rice capsule and two L. casei capsules were taken twice a day. The treatment lasted for 8 weeks, with an extended follow-up period of 4 weeks. The primary endpoint was a difference of serum low-density lipoprotein cholesterol (LDL-C) level at week 8. At week 8, the LDL-C serum level in both groups was lower than that at baseline, with a decrease of 33.85±26.66 mg/dL in the treatment group and 38.11±30.90 mg/dL in the control group; however, there was no statistical difference between the two groups (P>0.05). The total cholesterol was also lower than the baseline in both groups, yet without a statistical difference between the two groups. The only statistically signifificant difference between the two groups was the average diastolic pressure at week 12, which dropped by 2.67 mm Hg in the treatment group and increased by 4.43 mm Hg in the placebo group (P<0.05). The antihypertensive activity may be associated with L. casei. Red yeast rice can signifificantly reduce LDL-C, total cholesterol and triglyceride. The combination of red yeast rice and L. casei did not have an additional effect on lipid profifiles.

Xuezhikang capsule (XZK) is a traditional Chinese medicine that contains lovastatin (Lv) for hyperlipidemia treatment, although it has fewer side effects than Lv. However, the pharmacokinetic mechanisms contributing to its distinct efficacy and low side effects are unclear. Mice were fed a high-fat diet (HFD) for 6 weeks to induce hyperlipidemia. We first conducted the pharmacokinetic studies in HFD mice following oral administration of Lv (10 mg/kg, i.g.) and found that HFD remarkably decreased the active form of Lv (the lovastatin acid, LvA) exposure in the circulation system, especially in the targeting organ liver, with a declined conversion from Lv to LvA, whereas the Lv (responsible for myotoxicity) exposure in muscle markedly increased. Then we compared the pharmacokinetic profiles of Lv in HFD mice after the oral administration of XZK (1200 mg/kg, i.g.) or an equivalent dose of Lv (10 mg/kg, i.g.). A higher exposure of LvA and lower exposure of Lv were observed after XZK administration, suggesting a pharmacokinetic interaction of some ingredients in XZK. Further studies revealed that HFD promoted the inflammation and inhibited carboxylesterase (CES) activities in the intestine and the liver, thus contributing to the lower transformation of Lv into LvA. In contrast, XZK inhibited the inflammation and upregulated CES in the intestine and the liver. Finally, we evaluated the effects of monacolins and phytosterols, the fractional extracts of isoflavones, on inflammatory LS174T or HepG2 cells, which showed that isoflavones inhibited inflammation, upregulated CES, and markedly enhanced the conversion of Lv into LvA. For the first time, we provide evidence that isoflavones and Lv in XZK act in concert to enhance the efficacy and reduce the side effects of Lv.

The impact of Greece's economic crisis on healthcare is of great concern. The aim of the present study was to assess the impact of economic crisis on the prevention of cerebral ischemic events. Retrospective analysis of patients with ischemic stroke (IS) or transient ischemic attack (TIA) admitted to a tertiary neurological department in northwestern Greece during the period 2008-2014. Using 2011 as the transitional year IS/TIA patients were dichotomized according to their admission date in two subgroups: the "before economic crisis" subgroup and the "after economic crisis" subgroup. Logistic regression analyses were performed to identify predictor variables of statin/antihypertensive pretreatment. Patients admitted after the economic crisis outbreak (mean age: 57.6 ± 13.5 years) were found to have lower waist periphery measurements (p = 0.001), lower incidence of diabetes (p = 0.028), hyperlipidemia (p = 0.002) and metabolic syndrome(p < 0.001), at stroke onset with lower rates of antilipidemic treatment prescription prior to stroke onset compared to those patients with cerebral ischemia that were hospitalized before the financial crisis (mean age: 59.6 ± 11.1 years). However, between the two subgroups were no significant differences in the rates of untreated patients with hyperlipidemia (p = 0.189) and/or hypertension (p = 0.313). Even though statin pretreatment prior to stroke onset was found to be reduced during economic crisis compared to the period before the crisis, (OR = 0.58, 95%CI: 0.34-0.95, p = 0.032), this association did not retain statistical significance in the multivariate logistic regression analysis (OR = 1.69, 95%CI = 0.83-3.42, p = 0.143). Our study supports that at present financial crisis has not significantly affected the prevention of cerebrovascular events in the citizens of a provincial city area. Data from other regions and time-periods are needed for the final verdict. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

Rice has many health-beneficial components for ameliorating obesity, diabetes, and dyslipidemia. However, the effect of cooked rice as a useful carbohydrate source has not been investigated yet; so we hypothesized that cooked rice may have hypolipidemic effects. In the present study, we investigated the effect of cooked rice on hyperlipidemia and on the expression of hepatic genes involved in lipid metabolism. Golden Syrian hamsters were divided into 2 groups and fed a high-fat (15%, wt/wt)/cholesterol (0.5%, wt/wt) diet supplemented with either corn starch (HFD, 54.5% wt/wt) or cooked rice (HFD-CR, 54.5% wt/wt) as the main carbohydrate source for 8 weeks. In the HFD-CR group, the triglyceride and total cholesterol levels in the serum and liver were decreased, and the total lipid, total cholesterol, and bile acid levels in the feces were increased, compared with the HFD group. In the cooked-rice group, the messenger RNA and protein levels of 3-hydroxy-3-methylglutaryl CoA reductase were significantly downregulated; and the messenger RNA and protein levels of the low-density lipoprotein receptor and cholesterol-7α-hydroxylase were upregulated. Furthermore, the expressions of lipogenic genes such as sterol response element binding protein-1, fatty acid synthase, acetyl CoA carboxylase, and stearoyl CoA desaturase-1 were downregulated, whereas the β-oxidation related genes (carnitine palmitoyl transferase-1, acyl CoA oxidase, and peroxisome proliferator-activated receptor α) were upregulated, in the cooked-rice group. Our results suggest that the hypolipidemic effect of cooked rice is partially mediated by the regulation of hepatic genes involved in lipid metabolism, which results in the suppression of cholesterol and fatty acid synthesis and the enhancement of cholesterol excretion and fatty acid β-oxidation.

This study was performed to effects of garlic and lemon juice mixture on lipid profile and some cardiovascular risk factors in people 30-60 years old with moderate hyperlipidemia. In a parallel-designed randomized controlled clinical trial, a total of 112 hyperlipidemic patients 30-60 years, were recruited from Isfahan Cardiovascular Research Center. People were selected and randomly divided into four groups. Control blood samples were taken and height, weight, and blood pressure were recorded. (1) Received 20 g of garlic daily, plus 1 tablespoon lemon juice, (2) received 20 g garlic daily, (3) received 1 tablespoon of lemon juice daily, and (4) did not receive garlic or lemon juice. A study technician was done the random allocations using a random numbers table. All participants presented 3 days of dietary records and 3 days of physical activity records during 8 weeks. Blood samples were obtained at study baseline and after 8 weeks of intervention. Results showed a significant decrease in total cholesterol (changes from baseline: 40.8 ± 6.1, P < 0.001), low-density lipoprotein-cholesterol (29.8 ± 2.6, P < 0.001), and fibrinogen (111.4 ± 16.1, P < 0.001) in the Group 1, in comparison with other groups. A greater reduction in systolic and diastolic blood pressure was observed in Group 1 compared with the Groups 3 and 4 (37 ± 10, P = 0.01) (24 ± 1, P = 0.02); respectively. Furthermore, a great reduction in body mass index was observed in the mixed group compared with the lemon juice and control groups (1.6 ± 0.1, P = 0.04). Administration of garlic plus lemon juice resulted in an improvement in lipid levels, fibrinogen and blood pressure of patients with hyperlipidemia.

Cardiac catheterization showed the absence of left coronary system; the entire coronary system originated from the right aortic sinus as a common trunk which then gave off the right coronary artery and the left main coronary artery. Cardiac catheterization demonstrated also another rare coronary anomaly: dual left anterior descending artery. Patient underwent percutaneous coronary intervention and subsequent multidetector computed tomography angiography confirmed the above angiography findings. Patient was subsequently discharged home on double antiplatelet therapy with aspirin and clopidogrel and has been asymptomatic since then. PMID:27293909

Cardiovascular disease (CVD) is the leading cause of death in developed regions and a worldwide health concern. Multiple external causes of CVD are well known, including obesity, diabetes, hyperlipidemia, age, and sedentary behavior. Air pollution has been linked with the development of CVD for decades, though the mechanistic characterization remains unknown. In this comprehensive review, we detail the background and epidemiology of the effects of air pollution and other environmental modulators on the heart, including both short- and long-term consequences. Then, we provide the experimental data and current hypotheses of how pollution is able to cause the CVD, and how exposure to pollutants is exacerbated in sensitive states. Published 2017.

Acharan sulfate (AS) is a glycosaminoglycan (GAG) prepared from the giant African snail, Achatina fulica. In this study, some biological activities of AS were evaluated on the basis of structural similarities to heparin/heparan sulfate and the biological functions of GAGs. We demonstrated that it exhibited strong immunostimulating activities as measured by carbon clearance test in mice and in vivo phagocytosis. It also exhibited a significant hypoglycemic activity in epinephrine (EP)-induced hyperglycemia as well as antifatigue effects by weight-loaded forced swimming test. And it showed hypolipidemic activities in cholesterol-rich mixture induced hyperlipidemia in rats. The above results indicate that AS has diverse biological activities and suggest therapeutically important target molecules.

Applications of Two-Dimensional Electrophoresis Technology to the Study of Atherosclerosis

Atherosclerosis is a multifactorial disease in which hypertension, diabetes, hyperlipidemia and other risk factors are thought to play a role. However, the molecular processes underlying plaque formation and progression are not yet completely known. In the last years some researchers applied proteomics technologies for the comprehension of biochemical pathways of atherogenesis and to search new cardiovascular biomarkers to be utilized either as early diagnostic traits or as targets for new drug therapies. Due to its intrinsic complexity, the problem has been approached by different strategies, all of which have some limitations. In this review, we summarize the most common critical experimental variables in two-dimensional electrophoresis-based techniques and recent data obtained by applying proteomic approaches in the study of atherosclerosis.

Pregnant women are more prone to ketosis due to the relative insulin resistance, accelerated lipolysis and increased free fatty acids. We report a pregnant woman with hyperlipidemia, who experienced severe metabolic acidosis after a short period of starvation. Based on her clinical symptoms, exclusion diagnosis and therapeutic diagnosis, her condition was diagnosed as starvation ketoacidosis. An emergency caesarean section under general anesthesia was implemented 2 hours after her admission. The metabolic acidosis was treated with fluid resuscitation using compound sodium lactate, bicarbonate, and 5% dextrose together with insulin 6U. Both mother and baby were discharged clinically well. Starvation ketoacidosis may happen in special patient who was in pregnancy and with severe hypertriglyceridemia, after just one day fasting and vomiting.

Ces1g/Es-x deficiency in mice results in weight gain, insulin resistance, fatty liver and hyperlipidemia through upregulation of de novo lipogenesis and oversecretion of triacylglycerol (TG)-rich lipoproteins. Here, we show that restoration of Ces1g/Es-x expression only in the liver significantly reduced hepatic TG concentration accompanied by decreased size of lipid droplets, reduced secretion of very low-density lipoproteins and improved insulin-mediated signal transduction in the liver. Collectively, these results demonstrate that hepatic Ces1g/Es-x plays a critical role in limiting hepatic steatosis, very low-density lipoprotein assembly and in augmenting insulin sensitivity.

A medical diagnostic method and instrumentation system for analyzing noncovalently bonded agglomerated biological particles is described. The method and system comprises: a method of preparation for the biological particles; an electrospray generator; an alpha particle radiation source; a differential mobility analyzer; a particle counter; and data acquisition and analysis means. The medical device is useful for the assessment of human diseases, such as cardiac disease risk and hyperlipidemia, by rapid quantitative analysis of lipoprotein fraction densities. Initially, purification procedures are described to reduce an initial blood sample to an analytical input to the instrument. The measured sizes from the analytical sample are correlated with densities, resulting in a spectrum of lipoprotein densities. The lipoprotein density distribution can then be used to characterize cardiac and other lipid-related health risks.

Lovastatin is an effective drug for treatment of hyperlipidemia. This study aimed to clone lovastatin biosynthesis regulatory gene lovE and analyze the structure and function of its encoding protein. According to the lovastatin synthase gene sequence from genebank, primers were designed to amplify and clone the lovastatin biosynthesis regulatory gene lovE from Aspergillus terrus genomic DNA. Bioinformatic analysis of lovE and its encoding animo acid sequence was performed through internet resources and software like DNAMAN. Target fragment lovE, almost 1500 bp in length, was amplified from Aspergillus terrus genomic DNA and the secondary and three-dimensional structures of LovE protein were predicted. In the lovastatin biosynthesis process lovE is a regulatory gene and LovE protein is a GAL4-like transcriptional factor.

Bullous lichen planus (BLP) is a rare variant of lichen planus, characterized by the development of vesicular and bullous lesions, of skin, nails, hair and/or mucosa. We present a case of 63-year-old woman with BLP, unresponsive to previous therapies with topical corticosteroids, topical calcipotriol, antihistamines and oral cyclosporine (4 mg/kg/day for 4 months). She was already receiving treatment for arterial hypertension, hyperlipidemia, atrial fibrillation and uncontrolled diabetes mellitus. Acitretin was administered for 5 months with complete remission of BLP lesions and no major side effects. This is probably the first reported case of BLP treated with acitretin monotherapy. In this case acitretin was an efficacious and well-tolerated therapeutic option for BLP.

Metabolic Syndrome consists in a group of metabolic changes, being the most important problem insulin resistence. Other important components of this syndrome are abdominal obesity, hypertension and hyperlipidemia /hypercholestrolemia. It was demonstrated that psychiatric patients have a greater risk to develop metabolic syndrome with a prevalence of 41%. Prevalence of this syndrome in psychiatric male patients is 138% higher than in general population and in female patients 251% higher. Some of the factors that can explain this increase of metabolic risk in psychiatric patients are psychiatric drugs. We preformed a systematic review of literature published until June, 2007, by means of MEDLINE. Studies reviewed include clinical cases, reviews, analytic and observational studies. We selected 72 articles. Authors pretend to understand the mechanisms, by which, different psychiatric drugs can influence metabolic syndrome, and strategies for prevention of this situation.

Recently, the use of plant-derived medicines is increasing interest in the prevention and treatment of a variety of disorders including metabolic syndromes. Metabolic syndrome is one of the major risk factors for cardiovascular diseases (CVDs) and incidence of mortality worldwide. Scientific evidence suggests that Andrographis paniculata and its derived components, especially andrographolide (AGL) and its analogs/derivatives have a broad spectrum of biological activities. This review aims to sketch the activity of AGL and its analogs/derivatives against the components of metabolic syndromes such as diabetes, hyperlipidemia, hypertension, and obesity. Additionally, AGL activity against CVDs is also summarized. The finding suggests that AGL and its analogs/derivatives have a potential role in the management of metabolic syndrome; however, more studies should be conducted to evaluate their effectiveness.

Hyperglycemia, hyperlipidemia and impaired insulin signaling during the development of diabetes can cause diabetic complications, such as diabetic neuropathy, resulting in significant morbidity and mortality. Although various therapeutics are available for the treatment of diabetic neuropathy, no absolute cure exists, and additional research is necessary to comprehensively understand the underlying pathophysiological pathways. A number of studies have demonstrated the potential health benefits of bioactive compounds, i.e., flavonoids and vitamins, which may be effective as supplementary treatments for diabetes and its complications. In this review, we highlight the most recent reports about the mechanisms of action of bioactive compounds (flavonoids and vitamins) possessing potential neuroprotective properties in diabetic conditions. Additional clinical studies are required to determine the appropriate dose and duration of bioactive compound supplementation for neuroprotection in diabetic patients. PMID:27483315

To evaluate modifications on lipid profile, fibrinogen and platelet aggregation induced by etofibrate. Twenty-one adult patients were studied. They all had primary hyperlipidemia and had already been on the AHA step I diet and placebo. Etofibrate (500mg/day) was administered for 60 days in the active phase, when lipid parameters, fibrinogen and platelet aggregation were measured. The % significant reductions were: total cholesterol (-9.50%), LDL-cholesterol (-7.88%), triglycerides (-19.07%), total cholesterol/HDL-cholesterol(-11.90%), LDL-cholesterol/HDL-cholesterol (-10.20%), fibrinogen (-12.79%), platelet aggregation with adrenaline (-24.02%), with ADP 1 mumol (-30.13%), and ADP 3 mumol (-24.51%). The beneficial effects of etofibrate were observed not only on the lipid profile but also on the thrombogenic parameters measured by fibrinogen and platelet aggregation.

The Achilles tendon xanthoma is a rare disease and has a high association with primary hyperlipidemia. An early diagnosis is essential to start treatment and change the disease course. Imaging exams can enhance diagnosis. This study reports the case of a 60-year-old man having painless nodules on his elbows and Achilles tendons without typical gout crisis, followed in the microcrystalline disease clinic of Unifesp for diagnostic workup. Laboratory tests obtained showed dyslipidemia. The ultrasound (US) showed a diffuse Achilles tendon thickening with hypoechoic areas. Magnetic resonance imaging (MRI) showed a diffuse tendon thickening with intermediate signal areas, and a reticulate pattern within. Imaging studies showed relevant aspects to diagnose a xanthoma, thus helping in the differential diagnosis. Copyright © 2014 Elsevier Editora Ltda. All rights reserved.

Breastfeeding has many health benefits, both in the short term and the longer term, to infants and their mothers. There is an increasing number of studies that report on associations between breastfeeding and long-term protection against chronic disease. Recent research evidence is reviewed in this study, building on previous authoritative reviews. The recent World Health Organization reviews of the short- and long-term benefits of breastfeeding concluded that there was strong evidence for many public health benefits of breastfeeding. Cognitive development is improved by breastfeeding, and infants who are breastfed and mothers who breastfeed have lower rates of obesity. Other chronic diseases that are reduced by breastfeeding include diabetes (both type 1 and type 2), obesity, hypertension, cardiovascular disease, hyperlipidemia, and some types of cancer. © 2015 APJPH.

2016-01-01

Human ischemic stroke is very complex and no single preclinical model can comprise all the variables known to contribute to stroke injury and recovery. Hypertension, diabetes and hyperlipidemia are leading comorbidities in stroke patients. The use of predominantly young adult and healthy animals in experimental stroke research has created a barrier for translation of findings to patients. As such, more and more disease models are being incorporated into the research design. This review highlights the major strengths and weaknesses of the most commonly used animal models of these conditions in preclinical stroke research. The goal is to provide guidance in choosing, reporting and executing appropriate disease models that will be subjected to different models of stroke injury. PMID:27026092

Antihyperlipidemic therapies targeting PCSK9.

Weinreich, Michael; Frishman, William H

2014-01-01

Hyperlipidemia is a major cause of cardiovascular disease despite the availability of first-line cholesterol-lowering agents such as statins. A new therapeutic approach to lowering low-density lipoprotein-cholesterol (LDL-C) acts by blocking LDL-receptor degradation by serum proprotein convertase subtilisin kexin 9 (PCSK9). Human monoclonal antibodies that target PCSK9 and its interaction with the LDL receptor are now in clinical trials (REGN727/SAR23653, AMG145, and RN316). These agents are administered by either subcutaneous or intravenous routes, and have been shown to have major LDL-C and apolipoprotein B effects when combined with statins. A phase III clinical trial program evaluating clinical endpoints is now in progress. Other PCSK9-targeted approaches are in early stages of investigation, including natural inhibitors of PCSK9, RNA interference, and antisense inhibitors.

To observe the effect of Chinese medicine therapy combined with psychological intervention (combined therapy) on the clinical symptoms and levels of blood lipids and sex hormones of patients of peri-menopausal syndrome complicated with hyperlipidemia. With the use of a randomizing digital table method, 185 patients that fit the registration standard were randomly assigned to three groups. The 59 cases in Group A were treated with two Chinese patents, Kunbao Pill and Modified Xiaoyao Pill; the 63 in Group B received psychological intervention alone; and the 63 in Group C were treated with both (the combined therapy), with the treatment course for all six months. The items of observation included: (1) scoring by SCL-90 on eight factors and seven symptoms; (2) scoring on Chinese medicine symptoms by Kupermann scale, including anxiety and bad temper, scorching sense action with sweating, dizziness, tinnitus, soreness and weakness of the loin and knees, palpitation, insomnia, lassitude, weakness, and hyposexuality; (3) blood contents of total cholesterol (TC), triglyceride (TG), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), apoprotein AI (ApoAI) and B (ApoB); (4) levels of sex hormones, including estradiol (E(2)), progesterone (P), pituitary prolactin (PRL), follicular stimulating hormone (FSH), and), luteinzing hormone (LH) in some randomly selected patients; (5) adverse reaction; and (6) one-year follow-up study on long-term effect. A total of 21 patients (6, 8, and 7 cases in Groups A, B, and C, respectively) dropped out; the drop-out rate was insignificant among groups. (1) The markedly effective rates in Group A, B, and C were 26.42% (14/53), 18.18% (10/55), and 53.57% (30/56), respectively, and the total effective rates in them were 64.15% (34/53), 50.91% (28/55), and 87.50% (49/56), respectively, suggesting the therapeutic efficacy in Group C was significantly better than that in Groups A and B (P<0.01). (2) SCL-90 scoring showed that the total scores decreased significantly after treatment in Group C (P<0.01), but remained unchanged in Groups A and B (P>0.05). (3) Scoring on Chinese medicine symptoms showed the same results as shown by SCL-90 scoring in terms of total scores and individual symptoms, except that menstrual disorder and amenorrhea were unchanged in all three groups (P>0.05). (4) Levels of HDL-C, ApoAI, and E(2) increased and those of TG, TC, LDL-C, ApoB, FSH, and LH decreased after treatment in Group C, reaching near normal levels; similar trends of blood lipids were shown in Group A, but the level of sex hormones was unchanged. In Group B all the above-mentioned indices were unchanged (P>0.05). (5) A one-year follow-up study showed the markedly effective rate and the total effective rate in Group C were higher than those in the other two groups respectively (P<0.01). (6) No adverse reaction was found. Chinese medicine therapy combined with psychological intervention could not only improve the nervous symptoms, but also regulate the blood levels of lipids and sex hormones in patients of peri-menopausal syndrome complicated with hyperlipidemia.

We aimed to present our experience with carotid angioplasty and stenting (CAS) and to document how the technique evolved over the last decade (1997-2007). A retrospective study of 333 patients (259 men; median age, 69 years) who underwent 336 CAS procedures. Of these, 118 (35%) patients were symptomatic and 164 (49%) lesions involved the left carotid bifurcation. The first 163 patients received a balloon-expandable stent, whereas the remaining 173 received a self-expandable one. Cerebral protection devices were used in the last 84 (25%) procedures. Access was via the femoral artery in all but six cases, in which direct puncture ofmore » the common carotid was necessary. The left common carotid originated from the innominate artery in 18 cases (5%). Conversion to open endarterectomy was necessary in two patients due to inability to remove the filter. Perioperative neurological events included stroke in 6 patients (1.8%), transient ischemic attack in 15 (4.5%), and hyperperfusion syndrome in 10 (3.0%). Three patients died during the first 30 days. As a result, the mortality and the combined stroke/death rate were 0.9 and 2.4%, respectively, with no differences between symptomatic and asymptomatic patients. Bradycardia was noted in 48 patients (14%), and hypotension in 45 (13%). Univariate analysis identified hypertension (P = 0.03), hyperlipidemia (P = 0.02), and current or ex-smoking (P = 0.02) as significant risk factors for death/stroke. On multivariate analysis using logistic regression, only hyperlipidemia [odds ratio (OR), 53.90; 95% confidence interval (CI), 4.19-693.47; P = 0.002] and current or ex-smoking (OR, 63.84; 95% CI,: 4.80-848.68; P = 0.001) remained statistically significant. In conclusion, CAS can be performed safely and effectively, with acceptable mortality, stroke/death, and cardiovascular complication rates. Although technological advances (stent design, cerebral protection devices), perioperative pharmacological management, and increasing experience are all clinically significant factors influencing the short-term results, none appeared to be statistically significant in this patient sample.« less

Objective To examine the potential effect of a tax on palm oil on hyperlipidemia and on mortality due to cardiovascular disease in India. Design Economic-epidemiologic model. Modeling methods A microsimulation model of mortality due to myocardial infarction and stroke among Indian populations was constructed, incorporating nationally representative data on systolic blood pressure, total cholesterol, tobacco smoking, diabetes, and cardiovascular event history, and stratified by age, sex, and urban/rural residence. Household expenditure data were used to estimate the change in consumption of palm oil following changes in oil price and the potential substitution of alternative oils that might occur after imposition of a tax. A 20% excise tax on palm oil purchases was simulated over the period 2014-23. Main outcome measures The model was used to project future mortality due to myocardial infarction and stroke, as well as the potential effect of a tax on food insecurity, accounting for the effect of increased food prices. Results A 20% tax on palm oil purchases would be expected to avert approximately 363 000 (95% confidence interval 247 000 to 479 000) deaths from myocardial infarctions and strokes over the period 2014-23 in India (1.3% reduction in cardiovascular deaths) if people do not substitute other oils for reduced palm oil consumption. Given estimates of substitution of palm oil with other oils following a 20% price increase for palm oil, the beneficial effects of increased polyunsaturated fat consumption would be expected to enhance the projected reduction in deaths to as much as 421 000 (256 000 to 586 000). The tax would be expected to benefit men more than women and urban populations more than rural populations, given differential consumption and cardiovascular risk. In a scenario incorporating the effect of taxation on overall food expenditures, the tax may increase food insecurity by <1%, resulting in 16 000 (95% confidence interval 12 000 to 22 000) deaths. Conclusions Curtailing palm oil intake through taxation may modestly reduce hyperlipidemia and cardiovascular mortality, but with potential distributional consequences differentially benefiting male and urban populations, as well as affecting food security.

To assist in the long-term health management of residents and evaluate the health impacts after the Tokyo Electric Power Company's Fukushima Daiichi Nuclear Power Plant accident in Fukushima Prefecture, the Fukushima prefectural government decided to implement the Fukushima Health Management Survey. This report describes the results for residents aged 15 years or younger who received health checks and evaluates the data obtained from 2011 and 2012. The target group consisted of residents aged 15 years or younger who had lived in the evacuation zone. The health checks were performed on receipt of an application from any of the residents. The checks, which included the measurements of height, weight, blood pressure, biochemical laboratory findings, and peripheral blood findings, were performed as required. 1) A total of 17,934 (64.5%) and 11,780 (43.5%) residents aged 15 years or younger received health checks in 2011 and 2012, respectively. 2) In both years, a number of male and female residents in the 7-15 year age group were found to suffer from obesity, hyperlipidemia, hyperuricemia, or liver dysfunction. Furthermore, pediatric aged 15 years or younger were commonly observed to suffer from hypertension or glucose metabolic abnormalities. 3) A comparison of data from 2012 and 2011 demonstrated that both males and females frequently showed increased body height and decreased body weight in 2012. The prevalence of hypertension, glucose metabolic abnormalities, or high γ-GTP values in males and females in the 7-15 year age group in 2012 was lower than that in 2011. However, the prevalence of hyperuricemia among residents in the 7-15 year age group was higher in 2012 than in 2011. These results suggested that some residents aged 15 years or under who had lived in the evacuation zone had developed obesity, hyperlipidemia, hyperuricemia, liver dysfunction, hypertension, or glucose metabolic abnormalities. Therefore, we think that it is necessary to continue the health checks for these residents in order to ameliorate these lifestyle-related diseases.

AIM: To evaluate the effects of ursodeoxycholic acid (UDCA) and/or low-calorie diet (LCD) on a rat model of nonalcoholic steatohepatitis (NASH). METHODS: Fifty-five Sprague-Dawley rats were divided into five groups. The control group (n = 9) was fed with standard rat diet for 12 wk, NASH group (n = 10) was fed with high-fat diet consisted of normal diet, 10% lard oil and 2% cholesterol for 12 wk, UDCA group (n = 10) was fed with high-fat diet supplemented with UDCA at a dose of 25 mg/(kg·d) in drinking water for 12 wk, LCD group (n = 10) was fed with high-fat diet for 10 wk and then LCD for 2 wk, and UDCA+LCD group (n = 15) was fed with high-fat diet for 10 wk, followed by LCD+UDCA for 2 wk. At the end of the experiment, body weight, serum biochemical index, and hepatopathologic changes were examined. RESULTS: Compared with the control group, rats in the NASH group had significantly increased body weight, liver weight, and serum lipid and aminotransferase levels. All rats in the NASH group developed steatohepatitis, as determined by their liver histology. Compared with the NASH group, there were no significant changes in body weight, liver weight, blood biochemical index, the degree of hepatic steatosis, and histological activity index (HAI) score in the UDCA group; however, body and liver weights were significantly decreased, and the degree of steatosis was markedly improved in rats of both the LCD group and the UDCA+LCD group, but significant improvement with regard to serum lipid variables and hepatic inflammatory changes were seen only in rats of the UDCA+LCD group, and not in the LCD group. CONCLUSION: LCD might play a role in the treatment of obesity and hepatic steatosis in rats, but it exerts no significant effect on both serum lipid disorders and hepatic inflammatory changes. UDCA may enhance the therapeutic effects of LCD on steatohepatitis accompanied by obesity and hyperl-ipidemia. However, UDCA alone is not effective in the prevention of steatohepatitis induced by high-fat diet. PMID:15818751

To explore the longitudinal effect of metabolic syndrome (MetS) and its components on the development of non-alcoholic fatty liver disease (NAFLD) and to evaluate the significance of MetS and its components as early markers of NAFLD risk in a northern urban Han Chinese population. A total of 15,791 cohort members without NAFLD at baseline were included in the current study between 2005 and 2011. The baseline characteristics of the cohort were compared by MetS status at baseline and NAFLD status after follow-up. Cox proportional hazards models were used to estimate the unadjusted or adjusted hazard ratios (HRs) for development of NAFLD among individuals with MetS compared with individuals without MetS at baseline. During 51,652 person-years of follow-up, 3913 (24.78%) new cases of NAFLD occurred between 2005 and 2011. In the unadjusted model, the HR (95% confidence interval [CI]) for NAFLD was 2.51 (2.30, 2.73). After adjusting for gender, age, diet, smoking status, and regular exercise, the HR was 1.94 (1.78, 2.13). Gender differences were observed, with adjusted HRs (95% CIs) of 1.89 (1.71, 2.09) and 1.72 (1.43, 2.07) among males and females, respectively. Compared with individuals without MetS components, the HRs were 1.92 (1.76, 2.09), 2.64 (2.40, 2.90) and 3.51 (3.15, 3.91) for individuals with one, two, or three or more MetS components, respectively. Moreover, participants with obesity or hyperlipidemia had a higher risk of NAFLD than patients with hypertension or hyperglycemia, with HRs of 2.03 (1.83, 2.25) for obesity, 1.94 (1.72, 2.19) for hyperlipidemia, and 3.01 (2.68, 3.37) for these factors in combination. The present study indicates that MetS and its components independently predict the risk of NAFLD in a northern urban Han Chinese population and suggests that people with MetS or its component should initiate lifestyle changes to prevent the development of NAFLD.

Cyclosporine A and palmitic acid treatment synergistically induce cytotoxicity in HepG2 cells

DOE Office of Scientific and Technical Information (OSTI.GOV)

Luo, Yi, E-mail: yi.luo@pfizer.com; Rana, Payal; Will, Yvonne

Immunosuppressant cyclosporine A (CsA) treatment can cause severe side effects. Patients taking immunosuppressant after organ transplantation often display hyperlipidemia and obesity. Elevated levels of free fatty acids have been linked to the etiology of metabolic syndromes, nonalcoholic fatty liver and steatohepatitis. The contribution of free fatty acids to CsA-induced toxicity is not known. In this study we explored the effect of palmitic acid on CsA-induced toxicity in HepG2 cells. CsA by itself at therapeutic exposure levels did not induce detectible cytotoxicity in HepG2 cells. Co-treatment of palmitic acid and CsA resulted in a dose dependent increase in cytotoxicity, suggesting thatmore » fatty acid could sensitize cells to CsA-induced cytotoxicity at the therapeutic doses of CsA. A synergized induction of caspase-3/7 activity was also observed, indicating that apoptosis may contribute to the cytotoxicity. We demonstrated that CsA reduced cellular oxygen consumption which was further exacerbated by palmitic acid, implicating that impaired mitochondrial respiration might be an underlying mechanism for the enhanced toxicity. Inhibition of c-Jun N-terminal kinase (JNK) attenuated palmitic acid and CsA induced toxicity, suggesting that JNK activation plays an important role in mediating the enhanced palmitic acid/CsA-induced toxicity. Our data suggest that elevated FFA levels, especially saturated FFA such as palmitic acid, may be predisposing factors for CsA toxicity, and patients with underlying diseases that would elevate free fatty acids may be susceptible to CsA-induced toxicity. Furthermore, hyperlipidemia/obesity resulting from immunosuppressive therapy may aggravate CsA-induced toxicity and worsen the outcome in transplant patients. -- Highlights: ► Palmitic acid and cyclosporine (CsA) synergistically increased cytotoxicity. ► The impairment of mitochondrial functions may contribute to the enhanced toxicity. ► Inhibition of JNK activity attenuated palmitate/ CsA induced toxicity. ► Palmitate sensitizes cells to the toxicity induced by CsA at therapeutic exposure. ► Elevated free fatty acids may predispose the patients to CsA-induced toxicity.« less

Burden of non-communicable diseases (NCDs) is increasing rapidly in most of the developing countries including China, even in rural areas. Dearth of representative data called for an investigation to estimate the burden and identify the correlates of NCDs in rural China. A cross-sectional study was conducted involving a representative sample of 6003 consenting randomly selected rural residents aged 15 years or more, from 36 villages of Shijiazhuang in Hebei province of China between July 2010 and June 2011. Information on demographics and behavior were collected, body mass index (BMI) and blood pressure were measured and blood samples were tested to diagnose diabetes and hyperlipidemia. Majority participants were aged < 30 year, married and educated up to junior/senior high school level. Mean age for the 6003 participants was 37.4 ± 14.8. About 55.7% had BMI of 18.6-24.9. In past 12 months: 19.8% smoked daily, 41.6% were exposed to passive smoking, 28.5% drank alcohol, 10.4% skipped breakfasts frequently, 82.8% did never exercise and 25.3% had psychological disturbances. 51.1% were hypertensive, 6.7% were diabetic and 9.2% had hyperlipidemia. Based on self-reports, cardiovascular diseases (4.5%), cerebrovascular diseases (2.3%), cancers (0.2%), chronic obstructive pulmonary diseases (2%), orthopedic problems (12.1%) and gastrointestinal NCDs (7.8%) were identified among the participants, while proportion of subjects with one, two and three or more NCDs were 43%, 14.4% and 5.5% respectively. Higher odds of having more NCDs were associated with higher BMI (Kg/M(2)), family history of NCDs, daily and past history of smoking and drinking, passive smoking, lack of exercise, skipping breakfast and psychological disturbances. Despite limitations associated with cross-sectional design and self-reporting, observation in this large sample of rural residents could develop important insights regarding high burden of NCDs in this population. Based on the identified correlates, targeted intervention strategies seem to be required urgently to control NCDs in rural China.

The primary management of peptic ulcers is medical treatment. Persistent exacerbation of a peptic ulcer may lead to complications (perforation and/or bleeding). There has been a trend toward the use of a less invasive surgical simple suture, simple local suture or non-operative (endoscopic/angiography) hemostasis rather than acid-reducing vagotomy (i.e., vagus nerve severance) for treating complicated peptic ulcers. Other studies have shown the relationship between high vagus nerve activity and survival in cancer patients via reduced levels of inflammation, indicating the essential role of the vagus nerve. We were interested in the role of the vagus nerve and attempted to assess the long-term systemic effects after vagus nerve severance. Complicated peptic ulcer patients who underwent truncal vagotomy may represent an appropriate study population for investigating the association between vagus nerve severance and long-term effects. Therefore, we assessed the risks of subsequent ischemic stroke using different treatment methods in complicated peptic ulcer patients who underwent simple suture/hemostasis or truncal vagotomy/pyloroplasty. We selected 299,742 peptic ulcer patients without a history of stroke and Helicobacter pylori infection and an additional 299,742 matched controls without ulcer, stroke, and Helicobacter pylori infection from the National Health Insurance database. The controls were frequency matched for age, gender, Charlson comorbidity index (CCI) score, hypertension, hyperlipidemia history, and index year. Then, we measured the incidence of overall ischemic stroke in the two cohorts. The hazard ratio (HR) and the 95% confidence intervals (CIs) were estimated by Cox proportional hazard regression. Compared to the controls, peptic ulcer patients had a 1.86-fold higher risk of ischemic stroke. There were similar results in gender, age, CCI, hypertension, and hyperlipidemia stratified analyses. In complicated peptic ulcer patients, those who received truncal vagotomy and pyloroplasty had a lower risk of ischemic stroke than patients who received simple suture/hemostasis (HR = 0.70, 95% CI = 0.60-0.81). Our findings suggest that patients with peptic ulcers have an elevated risk of subsequent ischemic stroke. Moreover, there were associations between vagotomy and a decreased risk of subsequent ischemic stroke in complicated peptic ulcer patients.

Objective This study tests the hypothesis that BSN723T can prevent the development of hyperlipidemia and atherosclerosis in ApoE-/- knockout mice fed a Western (high fat, high cholesterol, and high sucrose) diet. BSN723T is a combination drug therapy consisting of D-tagatose and dihydromyricetin (BSN723). Background D-tagatose has an antihyperglycemic effect in animal and human studies and shows promise as a treatment for type 2 diabetes and obesity. Many claims regarding BSN723's pharmacological activities have been made including anti-cancer, anti-diabetic, anti-hypertensive, anti-inflammatory, and anti-atherosclerotic effects. To our knowledge this is the first study that combines D-tagatose and BSN723 for the treatment of hyperlipidemia and the prevention of atherosclerosis. Methods ApoE-deficient mice were randomized into five groups with equivalent mean body weights. The mice were given the following diets for 8 weeks: Group 1 - Standard diet; Group 2 - Western diet; Group 3 - Western diet formulated with D-tagatose; Group 4 - Western diet formulated with BSN723; Group 5 - Western diet formulated with BSN723T. Mice were measured for weight gain, tissue and organ weights, total serum cholesterol and triglycerides and formation of atherosclerosis. Results The addition of D-tagatose, either alone or in combination with BSN723, prevented the increase in adipose tissue and weight gain brought on by the Western diet. Both D-tagatose and BSN723 alone reduced total cholesterol and the formation of atherosclerosis in the aorta compared to mice on the Western diet. Addition of BSN723 to D-tagatose (BSN723T) did not increase efficacy in prevention of increases in cholesterol or atherosclerosis compared to D-tagatose alone. Conclusion Addition of either D-tagatose or BSN723 alone to a Western diet prevented weight gain, increases in total serum cholesterol and triglycerides, and the formation of atherosclerosis. However, there was no additive or synergistic effect on the measured parameters with the combination BSN723T treatment. PMID:27683620
