Active clinical trials for "Metabolic Syndrome"

The aim of the study was to analyse the independent and joint effects of the components of the metabolic syndrome (MetS) on the incidence of diabetes in people with impaired glucose tolerance (IGT) and to assess the effect of acarbose by MetS status. Double-blind placebo controlled trial, 1,368 patients, follow-up time 3.3 years. MetS by ATP III definition with fasting plasma glucose of ≥ 6.1 mmol/l as limit for impaired fasting glucose (IFG).

In obese children, low antioxidant vitamin intake and reduced antioxidant capacity are common. Weight reduction reduces subclinical inflammation in obese subjects, and, similarly, antioxidant vitamins have been shown to reduce the expression of proinflammatory cytokines. Moreover, antioxidants reduce oxidative stress which influences endothelial function and might play a crucial role in the pathogenesis of obesity-related disorders. Furthermore, overweight children and adults have a markedly increased risk for iron deficiency. The mechanism linking obesity with iron deficiency is unclear. Growing evidence suggests that the elevated inflammatory status associated with obesity increases circulating hepcidin and this contributes to iron deficiency. Weight reduction has been shown to be associated with reduced inflammation and serum hepcidin concentrations, and an improved functional iron state. Thus, reducing inflammation in obese children may improve iron metabolism and reduce their risk of iron deficiency. Therefore, positive effects on subclinical inflammation, hepcidin/iron status and metabolic risk factors in obese children during weight loss may be enhanced by supplementation with antioxidants. The aim of the present study is to investigate the effect of 4-month antioxidant supplementation on subclinical inflammation, hepcidin, iron status and components of the metabolic syndrome in overweight children undergoing an outpatient weight-loss program. Our hypotheses are: 1. During an outpatient weight loss program, antioxidant supplementation will reduce oxidative and inflammatory stress associated with obesity to a greater extent than weight loss alone. 2. This will have two effects, compared to weight loss alone: a.It will reduce circulating hepcidin concentrations, and improve iron status. b.It will improve metabolic and cardiovascular risk factors. Subjects The investigators plan to enroll 50 children who are participants in outpatient weight-loss programs in the German part of Switzerland. Enrollment will be done with the agreement and assistance of the physician supervising the weight-loss program, and the timing of the study measurements will be incorporated within the existing program schedule. It is anticipated that the baseline blood sample for this study will be obtained from the regular baseline venipuncture for the weight-loss study. Criteria for participation include age between 10 to 18 years and a BMI over the 85th percentile for age and sex. Exclusion criteria include major medical illnesses, including gastrointestinal, inflammatory, bleeding and/or endocrine disorders, a history of nephrolithiasis, unusual dietary habits (e.g. vegetarianism), major food allergies or intolerances (lactose, gluten), smoking, and use of chronic medications or vitamin/mineral antioxidant supplements. Study design The study will be a double-blind, randomized, placebo-controlled intervention trial. Children will be randomly assigned to one of two groups: antioxidant (AO) or placebo (P) supplement. If it is necessary to enroll children from different weight-loss programs, then randomization will be stratified by program. During the 4-month weight loss period, the AO group will consume oral supplements of ascorbic acid (500mg), alpha tocopherol (400 IU), and 50 µg selenium (all from Burgerstein Vitamins, Rapperswil-Jona, Switzerland) each evening with diner, whereas the P group will consume identical-appearing placebo supplements.

The purpose of this study is to investigate the metabolic effects of anti-androgens and oral contraceptive pills (OCPs), compared with placebo, in the treatment of women with PCOS. We hypothesized that controlling elevated androgen levels with either anti-androgens or OCPs would produce improvement in metabolic markers in PCOS women and would reduce their long term metabolic risk.

The purpose of this study is to test whether a supervised mixed aerobic and strength training (MAST) program is effective in improving overall physical fitness and blood flow in the brain and lowering risk factors of coronary artery disease (CAD) in women with metabolic syndrome.

Obese HIV-positive women with Metabolic Syndrome (HIV-MS) and obese HIV-negative women with Metabolic Syndrome will be studied before and after achieving moderate (6%-8%) diet-induced weight loss. The investigators hypothesize that health markers will improve in both groups but that the improvement will be blunted in the women with HIV-MS.

The aim of this randomized controlled study determine the efficacy of calorie restriction intermittent fasting diet in metabolic parameters and weight management among metabolic syndromes adults. It was done on metabolic syndrome patients, aged 18-65 years at an academic institution in Istanbul,Turkey. Subjects were divided into two groups; IER (Intermittent Energy Restriction-intervention group, calori restriction of 300-500kcal/d combined with 16:8 model Intermittent Fasting) and CER (Countinous Energy Restriction- control group continous restriction of 300-500kcal/d). Assessment was ascertained at baseline and 12 weeks. Blood samples were analyzed for lipid profile, fasting plasma glucose, ınsulin, HOMA-IR. Blood pressure and body composition were evaluated.

By 2050, the expanding world population will consume two-thirds more animal protein than it consumes today. The increase in chronic diseases associated with the generalization of these consumption patterns tend to understand the place of meat in our diets. All these elements participate to the reduction of animal proteins in favor of vegetable proteins in our food. The elderly are particularly affected by malnutrition, the prevalence of protein-energy malnutrition increasing with age and promoting the onset of morbidities. Without care, it leads to the worsening of physiological phenomena linked to aging such as loss of muscle functionality (sarcopenia) or reduction in bone density (osteoporosis) and increases the risk of falls - the main cause of dependence. However, in France, protein consumption declines significantly with age, even though requirements appear to be greater for the elderly. It is therefore a major challenge for our societies to ensure that the aging of the population and the increase in life expectancy are not synonymous with a reduction in the physical and mental capacities of individuals. Thus, it is essential to ensure that the recommendations for reducing the intake of animal proteins in favor of vegetable proteins can be applied without risk to aging populations, in particular on the human body cardiovascular risk of these populations.

This is the randomized trial to explore the effect of behavioral modification program (Tai Chi vs. self management) on adults with metabolic syndrome. The outcome variables include health behavior, metabolic syndrome indicators, quality of life.

This pilot study will investigate the enrichment type, in pancakes, most effective at improving markers of metabolic syndrome. Ready-made pancakes enriched with either docosahexaenoic acid (DHA), beta-glucan (BG) or anthocyanins (AC), alone or in combination of DHA+BG or DHA+AC, will be consumed for 4 weeks.

Subjects with hypertriglyceridemia and metabolic syndrome are being recruited and receive diet interventions with either a high-saturated fat diet or a low-fat high protein diet for 4 days (days 1-4) and a breakfast on day 5. Blood samples are collected on day 1 and day 5 to examine lipid levels and circulating monocyte phenotypes.
