The relation between obesity, abdominal fat deposit and the angiotensin-converting enzyme gene I/D polymorphism and its association with coronary hea…
2004
To analyse the relation between overweight, obesity and fat distribution with I/D polymorphism of the angiotensin-converting enzyme (ACE) gene and its association with coronary heart disease (CHD). Cross-sectional, case–control study. A total of 185 cases (141 males) who had suffered at least one episode of CHD and 182 controls (127 males). Body mass index, waist circumference, blood pressure, plasma total cholesterol, triglycerides, HDL cholestrol and fasting glucose were measured with standard methods, genotyping the I/D polymorphism of ACE gene. Obesity and abdominal fat deposit are associated with CHD in women, but not independently. We have found an association between obesity and abdo…
Serum lipid responses to phytosterol-enriched milk in a moderate hypercholesterolemic population is not affected by apolipoprotein E polymorphism or …
2011
Background/Objectives: The importance of both low-density lipoprotein cholesterol (LDLc) size and the apolipoprotein E (Apo E) in the atherogenic process is known, but there is little information with regard to the effect of phytosterols (PS) on these parameters. The aim of this study was to evaluate the influence of PS on lipid profile and LDLc size according to Apo E genotype. Subjects/Methods: This was a randomized parallel trial employing 75 mild-hypercholesterolemic subjects and consisting of two 3-month intervention phases. After 3 months of receiving a standard healthy diet, subjects were divided into two intervention groups: a diet group (n = 34) and a diet+PS group (n = 41) that re…

Comparability of two different polyacrylamide gel electrophoresis methods for the classification of LDL pattern type
2011
Abstract Background The measurement of small dense low-density lipoprotein (sdLDL) particles is relevant when assessing cardiovascular risk. However, there is as yet no referenced method for the determination of LDL subfractions or a standardized comparison of the methods currently available. Therefore, the aim of this study was to compare the pattern of LDL particles measured by polyacrylamide tube gel electrophoresis (PTGE) and polyacrylamide gradient gel electrophoresis (PGGE) and to correlate the results with triglyceride concentration. Materials and methods Serum samples were collected from 177 patients. Lipid profile and LDL particle size were assessed using PTGE and PGGE. Results Pea…
Levels of C3 in patients with severe, morbid and extreme obesity: its relationship to insulin resistance and different cardiovascular risk factors.
2007
Increased C3 has been related to body mass index (BMI) and insulin resistance, although there are not sufficient studies in subjects with morbid obesity. The purpose of this study was to evaluate the levels of C3 as a function of the BMI in subjects of both sexes, with severe, morbid and extreme obesity, and their possible relationship to insulin resistance or associated diseases such as diabetes, hypertension and dyslipidemia.The study included a total of 316 patients (110 men and 206 women) with severe obesity (17.1%), morbid obesity (54.4%) and extreme obesity (28.4%), with an average BMI of 46.70+/-7.37 kg/m2.The glucose and insulin levels were determined baseline, and 2 h after a 75 g …
Effects of phytosterol ester-enriched low-fat milk on serum lipoprotein profile in mildly hypercholesterolaemic patients are not related to dietary c…
2010
Phytosterols (PS) are recommended to reduce LDL-cholesterol. However, the influence of cholesterol and fat intake on the lipid-lowering effect of PS in mildly hypercholesterolaemia is unclear. Thus, the aim of the present study was to evaluate whether the efficacy of PS is related to the composition of saturated fat and dietary cholesterol intake. Additionally, serum carotenoid content was analysed to evaluate to what extent it was undermined by PS. This was a 3-month randomised, parallel trial with a three-arm design. Patients were divided into three groups: healthy diet (n 24), healthy diet + PS (n 31) and free diet + PS (n 29), receiving 2 g/d of PS. Healthy and free diets were character…
Evaluation of cardiovascular risk and oxidative stress parameters in hypercholesterolemic subjects on a standard healthy diet including low-fat milk …
2010
A healthy diet and plant sterols (PS) are recommended for reducing low-density lipoprotein (LDL) cholesterol and, subsequently, the risk of premature cardiovascular disease PS mediate a decrease in fat-soluble vitamin concentration, which can lead to a general impairment of antioxidative defenses and an increase in oxidative stress. Thus, we evaluated the effects of a healthy diet, including PS-enriched low-fat milk, on cardiovascular risk and oxidative stress parameters in hypercholesterolemic subjects. This was a randomized parallel trial employing 40 subjects and consisting of two 3-month intervention phases. After 3 months on a standard healthy diet, subjects were divided into two inter…
Metabolic disorders and inflammation are associated with familial combined hyperlipemia
2019
Background: Familial Combined Hyperlipidemia (FCH) is related to different metabolic disorders. The objective of this study was to evaluate the presence of alterations of hydrocarbonated metabolism and lipid profile together with inflammatory and adhesion molecules in subjects with FCH compared to controls. Methods: 75 HFC patients and 75 healthy individuals were studied. Glucose, insulin, HOMA-IR index and lipid parameters, in addition to anti-oxidized LDL antibodies (Anti ox-LDL), small and dense LDL (sdLDL) and HDL subfractions, proinflammatory cytokines and adhesion molecules were measured. Results: FCH patients showed higher levels of hydrocarbonated metabolism parameters, total choles…
Low intestinal cholesterol absorption is associated with a reduced efficacy of phytosterol esters as hypolipemic agents in patients with metabolic sy…
2010
Summary Background & aims Phytosterols (PS) lower LDLc, but their effect on metabolic syndrome (MetS) remains unknown. We evaluated whether low-fat milk enriched with PS improves cardiovascular risk factors in these patients. Methods A randomised parallel trial employing 24 moderate-hypercholesterolaemic MetS patients and consisting of two 3-month intervention phases. After a 3-month healthy diet, patients were divided into two intervention groups: diet (n = 10) and diet + PS (n = 14) (2 g/day). A control group of 24 moderate-hypercholesterolaemic patients without MetS (matched in age and BMI) underwent the same procedure. Results Neither dietary intervention nor enrichment of PS induced an…
