Active clinical trials for "Metabolic Syndrome"

An abdominal distribution of fat is associated with the greatest heart disease risk, because commonly, several risk factors of metabolic origin cluster in these individuals. When this occurs the condition is called the 'metabolic syndrome'. Increased activity of the sympathetic nervous system resulting in enhanced release of the stress hormone 'noradrenaline', may be one mechanism by which adverse cardiovascular and metabolic sequela of the metabolic syndrome might be mediated. Impaired insulin action may be one factor contributing to increased noradrenaline release. The aim of this Study is to determine whether treatment with a drug called pioglitazone which is known to improve insulin action, results in reduced sympathetic nervous system activity and stress hormone release when compared to treatment with a dummy drug (placebo).

A huge body of scientific evidence has suggested that xanthohumol (XAN) consumption, a polyphenol present in beer, has a positive effect on energy metabolism. This compound is known for its antioxidant, anti-inflammatory and anti-cancer properties which confer potential to be used as a food supplement. Nevertheless, XAN lipophilic properties prevent the extensive use of this molecule as a functional food compound. The company TA-XAN S.A.M. (Wiesbaden, Germany) has patented a method to overcome this solubility problem. So, the main aim of this study is to evaluate the effects of XAN consumption on metabolic syndrome progression in individuals recently diagnosed.

To study the effects of Hesperidin supplement in patients with metabolic syndrome, 50 patients will be randomly allocated to control group or 2 capsules Hesperidin for 12 weeks; both groups will be advised to adherence the investigators' diet and exercise program too. At the first and the end of the intervention, metabolic factors will be assessed and compared between groups.

The aim of study is to assess the angioprotective effects of antihypertensive combination therapy with perindopril 10 mg and moxonidine 0.4-0.6 mg in patients with arterial hypertension, metabolic syndrome, and obesity, who had Pulse Wave Velocity (PWV) > 10 m/s on the previously administered two-component combination antihypertensive therapy. Open-label non-comparative prospective study for 24 week for each patient.

Several crosssectional and prospective studies have shown that metabolic syndrome and its related components are associated with both prevalent and incident CKD . Although the mechanisms for these cardiovascular benefits of Metformin and vildagliptin remain unclear, they extend well beyond glycemic lowering, and therefore are probably best considered diverse "cardiometabolic" pharmaceuticals rather than simply type 2 diabetes drugs. Metformin and vildagliptin have known vasculoprotective actions, but the value of these drugs on drug-naïve diabetic patients during 24 week use warrants investigation. The investigator's purpose was to observe their effects on weight control, Cardiometabolic Risk Factors, Metabolic Syndrome risk, and diabetic nephrooathy Progression.

With current antiretroviral therapy, people living with HIV reach virological suppression faster, which in turn leads to a higher life expectancy. Nevertheless, this improved survival rate is not free of other comorbidities, such as metabolic syndrome, characterized by a decrease in glucose tolerance and an increase in insulin resistance. Berberine is an alkaloid that has proven beneficial effects on both glucose tolerance and insulin resistance, but has not been tested in people living with HIV under virological suppression. We hypothesize that berberine will improve inflammatory markers and metabolic profile in this population without significant interactions nor adverse effects.

The aim of this project is to study the relationship between obstructive sleep apnea (OSA) and metabolic syndrome (MS) in a population of obese patients who are candidates for bariatric surgery. The investigators will study the influence of OSA through hypoxia and sleep fragmentation on different proinflammatory adipokines and cytokines, on metabolic syndrome and on insulin resistance, as well as how these respond to treatment with continuous positive airway pressure (CPAP). In the first part of the study (part A) the investigators will perform an observational study of cases and controls. Based on the diagnostic polysomnography the patients will be divided into two groups depending on their apnea-hypopnea index (AHI): OSA (AHI >= 15/h) and non-OSA (AHI <15/h). The results will be analyzed depending on the presence or not of OSA. In the second part of the study (part B), the patients with severe OSA (AHI ≥ 30/h) will be randomized into two groups: one group will receive CPAP + diet treatment and the other group will only receive diet treatment. After 3 months of treatment (CPAP + diet vs. diet), the investigators will analyze the overall effect on metabolic syndrome and the effect on its individual components, as well as the above-mentioned inflammatory pathways and insulin sensitivity, between the 2 groups. This will be carried out through a randomized controlled study in which the investigators will compare the effect of CPAP with the effect of conservative treatment.

Background: Several studies have suggested that clozapine has the greatest propensity of all available atypical antipsychotics to induce weight gain and metabolic dysregulation. So it is necessary to conduct some interventions to prevent or treat metabolic dysregulation induced by clozapine. Metformin has been reported to achieve weight loss in several groups of patients characterized by insulin resistance. Several studies evaluated the effects of metformin on antipsychotics-induced weight gain and study period lasted from 8 to 16 weeks. Long-term metformin use had more robust effect on metabolic dysregulation and body weight in non-psychiatric field. Goals: The study goals are two-fold. The first goal is to estimate the prevalence of metabolic dysregulation among clozapine-treated schizophrenic patients in Taiwan. The second goal is to assess the reversal effect of metformin on metabolic disturbance among clozapine-treated schizophrenic patients in a 24-week double-blind, placebo-control trial. The investigators will use metformin 1500 mg/d or placebo in the second phase trial. Methods: This study will be divided into two phases. The first phase is to estimate the prevalence of metabolic disturbances among clozapine-treated patients. The second will be a randomized, double-blind, and placebo-controlled study of adjunctive metformin for non-DM clozapine-treated patients. The clozapine dosage was maintained unchanged during the study period. The eligible patients will be randomly assigned to either metformin or identical placebo pills. Metformin will be titrated to 1500 mg/day in 4 weeks. Patients' blood pressure (BP), waist circumference, body weight, fasting plasma glucose (FPG), triglyceride (TG), high-density lipoprotein cholesterol (HDL), insulin, and leptin will be measured at 2, 4, 8, 16, and 24 weeks after the start of metformin. In a 3-year period, the investigators estimate to recruit 150 clozapine-treated patients in the first phase and 75 fulfill the second phase criteria. The investigators estimate 60 patients complete the second phase intervention (staying in second phase at least 4 weeks). From this study, the investigators would like to know the prevalence of metabolic dysregulation among clozapine-treated schizophrenic patients and to know the effect of metformin on metabolic profile among non-DM clozapine treated patients.

The purpose of this study is to identify salivary biomarkers for monitoring cardiometabolic risk in children. The study hypothesis is that a combination of salivary biomarkers will predict the presence of risk factors including impaired fasting glucose, hypertension and dyslipidemia and will reflect changes in these risk factors over time.

The human adipose and muscle -tissue produce and release a number of bioactive proteins which contributes to the chronic low grade of inflammatory status which is associated with obesity and plays an important role in the pathogenesis of type 2 diabetes and cardiovascular diseases. Study 1: Our aim is to investigate if exercise has independent and additive effects in combination with diet-induced weight loss on circulating levels of inflammatory markers and mRNA levels in subcutaneous adipose tissue (SAT) and skeletal muscle tissue (SM. Study 2: Our aim is to investigate whether gender and weight status plays a role in the metabolic response during two hours of acute exercise
