Active clinical trials for "Metabolic Syndrome"

A diagnosis of gestational diabetes mellitus (GDM)has significant implications for the future health of the mother. GDM is often the culmination of years of unrecognized and unmodified diabetes risk factors that lead to overt and occult clinical manifestations during pregnancy. Systematic reviews of older studies conclude that 35-60% women with gestational diabetes will develop type 2 diabetes (DM2) at rates much greater than control groups who did not have glucose intolerance during pregnancy. Liraglutide may potentially delay disease progression in GDM considering the beta -(ß-)cell function improvement in DM2 and ß-cell mass shown to increase in animal models. This study will examine if the addition of liraglutide to metformin therapy is more effective than metformin alone in improving insulin sensitivity and normalizing insulin secretion in at-risk overweight/obese women with prior GDM.

Obesity and metabolic syndrome are linked by inflammation. Gut flora seems to play an important role in the development of inflammation and metabolic syndrome in obesity. Modulation of gut flora by probiotics has been shown in animal studies to positively influence inflammation and metabolic disturbances. Lactobacillus casei Shirota is able to decrease metabolic endotoxemia by altering gut flora composition and gut permeability which leads to an improvement in neutrophil function and insulin resistance in obesity. The aim of the current study is to investigate the effect of Lactobacillus casei Shirota supplementation over 12 weeks on neutrophil function (phagocytosis, oxidative burst and TLR expression) in patients with metabolic syndrome. Furthermore the investigators aim to investigate the effect of Lactobacillus casei Shirota supplementation over 12 weeks on glucose tolerance, insulin resistance, inflammation, gut flora composition, gut permeability, and endotoxemia in metabolic syndrome

Pulses have the potential to be positioned as a food for body weight and metabolic control based on their composition, effects on rate of digestion and absorption of fat and carbohydrates, and effects on satiety. However, the role of individual pulses incorporated into a mixed meal on regulation of food intake, satiety and glycaemic control remains unclear. Therefore, the objective of our study was to determine the effects of ad libitum consumption of pulse meals (treatments) on food intake at an ad libitum pulse meal, food intake at an ad libitum pizza meal at four hours, subjective appetite and blood glucose.

This randomized pilot clinical trial studies atorvastatin calcium in preventing metabolic syndrome in patients with prostate cancer receiving long-term androgen-deprivation therapy. Atorvastatin calcium may help prevent or reduce metabolic syndrome caused by long-term androgen-deprivation therapy

Traditionally, obesity is considered an indirect cause of heart disease. Obese individuals typically present with a number of traditional Framingham risk factors (hypertension, dyslipidemia, and type 2 diabetes), predisposing them to heart attacks and subsequent heart failure. However, an emerging body of basic research revisits a hypothesis that fat is a direct cardiotoxin. Under healthy conditions, most triglyceride is stored in fatty tissue (adipocytes) while the amount of triglyceride stored in non-adipocyte tissues (such as the pancreas, the liver, skeletal muscle, and heart) is minimal and very tightly regulated. When this regulation is disrupted, intracellular triglyceride accumulates excessively in these organs ("steatosis") and has been implicated in activating adverse pathways which culminate in irreversible cell death ("lipotoxicity"), leading to several well-recognized clinical syndromes. These include non-alcoholic steatohepatitis (NASH), pancreatic beta-cell failure in type 2 diabetes, and dilated cardiomyopathy. It has been recently observed that angiotensin II receptor blockers (ARBs) in addition to lowering blood pressure improve insulin sensitivity and decrease the risk for type 2 diabetes. This study will test the above theory in two study groups: Valsartan vs. Hydrochlorothiazide. We hypothesize that in obese humans with elevated myocardial triglycerides, blockade of the renin-angiotensin system (Valsartan group) will reduce myocardial fat with improvement of insulin sensitivity and heart function.

SYSDIET (Systems biology in controlled dietary interventions and cohort studies) is one of the three centres in the NCoE Food, Nutrition and Health, 2007-2011. It consists of 12 partners from five Nordic countries working on multidisciplinary fields of science related to nutritional biology. The main objective of SYSDIET is to reveal mechanisms by which Nordic foods and diets could be modified to promote health and prevent insulin resistance, type 2 diabetes and cardiovascular diseases, all of which being connected to metabolic syndrome. Furthermore, the aim is to build up a Nordic platform for cohort studies and carefully conducted multi-centre dietary intervention studies, where novel nutritional systems biology tools can be applied besides human studies also in animal and cell culture studies. In order to achieve the main objective a Nordic multi-centre randomized controlled human intervention study is being conducted in 2009-2010 in 6-8 centres of SYSDIET consortium. Health of the Nordic populations has substantially improved during the last 30 years. This is due e.g. to marked decline in cardiovascular morbidity and mortality. However, during the last 10-20 years increasing obesity and sedentary lifestyle have resulted in an increase of metabolic syndrome and type 2 diabetes. Having this background, the aim of the SYSDIET consortium is to carry out a controlled, randomized dietary intervention study in persons with features of metabolic syndrome to find out the effects of a healthy Nordic food on major abnormalities in metabolic syndrome. Altogether 167 persons aged 30 to 65 years were recruited from 6-8 centers (40-60 subjects/center) of the SYSDIET cohort. The main inclusion criterion is BMI 27-38 kg/m2. The subjects should also have at least two other IDF criteria for metabolic syndrome. Recruited persons will start the study by following their conventional diet for one month as a run-in period. After that subjects will be randomly assigned into Experimental- or Control-diet-group for 6 months. Experimental diet is rich in whole grain products, berries, fruits, vegetables and fish, and its fat intake is modified according to current Nordic recommendations. Control diet is based on the current information of the mean dietary intake and food consumption. The diets will be realized according to eating habits in each Nordic country.

Recent population studies have shown that the glycemic index (GI) of food products is positively associated with the risk of developing type 2 diabetes and cardiovascular disease (CVD). In the pathogenesis of type 2 diabetes and CVD, inflammatory processes play a pivotal role. In a previous intervention study (11 weeks), however, we found no effects of lower-GI vs. higher-GI diets on fasting inflammatory markers in subjects with increased risk of developing the metabolic syndrome. People, however, spent most of their time in the postprandial period. Therefore, there is a need to study the postprandial effects of low-GI vs. high-GI diets. In addition, it needs to be emphasized the GI is derived from studies in lean subjects, while especially overweight and obese people suffer from metabolic aberrations related to the development of type 2 diabetes and CVD. AIM: To investigate in obese subjects the postprandial effects of a low-GI vs. high-GI food product on metabolic risk markers. A second research objective is to compare these effects with those in lean subjects.

The purpose of this study is to determine how a decline in physical activity acutely leads to a decrease in insulin sensitivity in skeletal muscle. The hypothesis is that the loss of insulin sensitivity following physical inactivity is caused by a rapid reduction in skeletal muscle mitochondrial oxidative capacity.

The purpose of this study is to determine if a low fructose intake could have an impact on weight loss, uric acid levels and the components of the metabolic syndrome (glucose, cholesterol, triglycerides, insulin resistance, high blood pressure).

An educational intervention in the General Medicine Clinic aimed at both primary care providers (PCPs) and their patients with metabolic syndrome/pre-diabetes (MetSyn/PDM). Improving PCPs ability to detect and manage MetSyn/PDM, as measured by the increased incorporation of MetSyn/PDM into PCPs care plan, and increasing patients' awareness of healthy lifestyle behaviors results in positive patient health behaviors and outcomes.
