Active clinical trials for "Metabolic Syndrome"

The purpose of this study is to investigate the safety and tolerability of MB12066 after a single or multiple oral dose and to investigate the pharmacokinetic characteristics of MB12066 after a single or multiple oral dose.

The investigators performed a 12-week, randomized, double-blind, placebo-controlled crossover human trial to evaluate the efficacy and safety of chungkookjang on improvement of metabolic syndrome. The investigators measured decrement of body fat parameters, including Body Fat Mass, Percent Body Fat, Fat Free Mass, Weight and BMI(body mass index), and monitored their blood pressure.

The study aims are to test whether the use of promotoras significantly impacts the health attitudes, health seeking behaviors, and patient confidence in self-managing health of rural Hispanic adults who have been diagnosed with metabolic syndrome. Specifically, the study is designed to address four areas of inquiry: 1) identification of patient attitudes involving: a) trust in medical providers and in the health care system, b) procedural fairness in treatment, c) provider and patient communication patterns, d) potential cultural bias in treatment, and e) healthy lifestyle behavior adoption/maintenance, 2) selected clinical indicators of metabolic syndrome (blood pressure, height/weight/BMI, blood glucose, hemoglobin A1c, and cholesterol), 3) the cultural competence of medical providers from the perspective of both the provider and the patient, and 4) patient self-management confidence scores.

The objective of this study is to address the anti-thrombotic effects of tocotrienols supplementation via modulation of platelet activation, thrombotic markers, inflammatory markers and endothelial function. It is hypothesized that 2 weeks supplementation of tocotrienols will be able to suppress platelet aggregation in subjects with metabolic syndrome.

The traditional risk factors for obesity are inappropriate diet, lack of exercise and genetic factors. However, recent observations have involved gut microbiota profiles as having an additional influence. In this case, there exists the possibility to modulate this through diet. Research has shown that the gut microbiota of both obese humans and mouse models of obesity is altered towards less beneficial one compared to lean counterparts. This raises the possibility of modulating the gut microbiota as a novel strategy in tackling the epidemic of obesity and diabetes sweeping the developed world. In addition, a more direct effect of high-fat induced disruption of the intestinal microbiota has also been seen with a murine model. Elevated circulating levels of lipopolysaccharide (LPS) a major building block and antigen of Gram-negative bacteria, was shown to generate a low grade chronic inflammation, termed metabolic endotoxemia, which then onsets insulin resistance. High-fat diets were shown to disrupt the Gram-negative intestinal populations of these animals, liberating LPS. The effects of prebiotics on the microbiota or metabolic syndrome (combination of disorders that increase the risk of developing cardiovascular disease and diabetes) in overweight adults have not been investigated thus far. The investigators therefore propose to investigate the effect of galactooligosaccharide (GOS) on the faecal microbiota and metabolic syndrome risk factors in overweight adults in a double-blind, randomised, placebo controlled, cross-over trial.

The purpose of this study is to determine the effects of mineralocorticoid receptor (MR) antagonism and renin inhibition on glucose metabolism in humans.

Dehydrated fruit and vegetable concentrates provide an accessible form of phytonutrient supplementation that may offer cardioprotective effects. This study assessed the effects of encapsulated fruit and vegetable juice powder concentrates on endothelial function and cardiac risk markers in subjects in a randomized, double blind, placebo controlled crossover clinical trial with three treatment arms.

The aim of this study is to explore if a 8-weeks dietary intervention with polyphenols and omega 3 fatty acids (alone or combined) may be effective on postprandial lipids metabolism and other cardiovascular risk factors in people at high cardiovascular risk.

The purpose of this study is to compare the effects of the antioxidant "resveratrol" to a diet intervention (Calorie Restriction) to determine how each of them affects the following: gene expression profile, cholesterol (lipids), how well the hormone insulin works to control your blood sugar, and other blood and tissue markers of metabolic and cardiovascular health. Resveratrol is found in grape skin, wine, peanuts, and mulberries and is thought to have health benefits such as improving fat metabolism, insulin action, and possibly extending lifespan. Resvida™ is the name for the dietary supplement containing the natural antioxidant "resveratrol". Resvida™ will be supplied by DSM Nutritional Products, Ltd. Resvida™ is considered a dietary supplement, and therefore it is not an approved drug by the Food and Drug Administration (FDA). It is regulated like a food. The U.S. Food and Drug Administration does not strictly regulate herbs and dietary supplements. The makers of Resvida™ make no claim that this supplement is meant to treat any ailment. Calorie restriction (CR) is a low calorie diet (about 30% fewer calories than the American Dietetic Association (ADA) recommends). Calorie restriction has also been linked to health benefits (enhanced cardiovascular and metabolic health) and an extended lifespan. This study is designed to compare the health benefits of both resveratrol and CR and to determine if resveratrol mimics some of the health benefits shown with CR.

Rationale: The prevalence of the metabolic syndrome is strongly increasing in developed countries. The role of the small intestine seems important in the development of the metabolic syndrome. Although it is known that a high-fat Western-style of diet has deleterious effects on (post-prandial) lipidemia and glucose homeostases, effects of such a diet on the small intestine is not known. To elucidate the role of the small intestine on the early development of the metabolic syndrome, the effects of a high-fat (HF) and a low-fat (LF) diet will be examined on gene expression in the small intestine and early biomarkers in blood of healthy subjects. Objective: The objective of this study is to compare in healthy subjects the effects of a HF diet (40 En% fat) with those of a LF diet (20 En% fat) on early biomarkers and parameters of metabolic stress in blood and on expression of genes in the small intestine. Additional research objectives are: To compare the diet-induced changes in transcriptome profile of the small intestine with more easily accessible peripheral blood mononuclear cells (PBMC) To establish effects of HF and LF diet on basal gut permeability and after a chenodeoxycholic acid (CDCA) load (second hit). Study design: Randomised crossover design. The duration of the experimental periods (HF and LF diet) will be 28 days, separated by a wash out period of at least 3 weeks. At day 21 of each intervention period a postprandial test will be performed and duodenum biopsies will be taken. At day 25 and 28 of each intervention period, respectively, basal gut permeability and gut permeability after a CDCA load will be determined with a sugar recovery test. Study population: Ten healthy men in the age of 18-60 years, without a history of any gastrointestinal disorders or complaints. Intervention: Subjects will consume in random order: a HF diet (40 En% fat, 45 En% carbohydrates and 15 En% proteins) a LF diet (20 En% fat, 65 En% carbohydrates and 15 En% proteins) Primary study parameters/endpoints: Potential early biomarkers of the metabolic syndrome in blood and gene expression profiles in the small intestine. Secondary study parameters/endpoints: Parameters of the metabolic syndrome in blood, gene expression profiles in PBMC and gut permeability.
