Active clinical trials for "Glucose Intolerance"

This work aimed to evaluate the acute effect of a black bean protein hydrolysate (BPH) on glucose levels in adults with normal glucose tolerance (NGT) and prediabetes. Twenty peptides were identified in BPH, and a followed in silico predictive digestion showed a release of several short-chain peptides with potential hypoglycemic potential. A double-blind, placebo-controlled, randomized clinical trial was conducted on 28 adults with NGT or prediabetes. After consent, participants were randomized into two groups, placebo or the corresponding 5 g BPH treatment. An oral glucose tolerance test (OGTT) (75 g glucose) was used to measure glucose tolerance before treatment. A second OGTT was used to evaluate the acute effect of the BPH, and blood samples were collected at 0, 60, 120, and 150 min, and blood glucose levels were measured.

The effects of strawberry and sea buckthorn on postprandial glycaemia and insulinemia as well as on metabolic profiles were examined in overweight or obese male subjects. The study was conducted as a randomised, controlled, single-blinded, 3-way crossover study. Eighteen subjects were studied in three 2 h meal tests followed by a subsequent ad libitum meal. Test meals contained either sea buckthorn, strawberry or no berries and added sucrose to match with respect to sucrose content. Blood samples were collected at baseline and several times postprandially. Subjective appetite sensations were recorded at baseline and every 15-20 min until 140 min and a subsequent ad libitum intake was recorded. Urine samples were also collected at baseline and at several time intervals until 24 hours. Blood and urine were subjected to metabolic profiling to investigate potential biomarkers of berry intake.

This study is a randomized intervention that will test two different approaches reflecting diverse levels of both intensity and cost, to achieving risk reduction of T2D. This will help address a critical question in the translation of primary prevention research into the public health: how much intensity (and thus cost) is required to achieve an effective outcome? In addition, the proposed study will address a critical need in diabetes prevention that has not received sufficient scholarly attention: the prevention of T2D in children. No studies of diabetes prevention similar in scope to the DPP have been performed in school-aged children; however, reducing childhood obesity is widely accepted as the primary pathway to decreasing the growing prevalence of T2D in the pediatric population.

Hypothesis. To determine the effect of metformin on the concentrations of resistin and other insulin resistance or inflammatory markers (C-reactive protein, cytokines, body weight, HbA1c, among others) in minors with glucose intolerance. Children with glucose intolerance are given either metformin or placebo for 12 consecutive weeks. High sensitivity C-reactive protein, TNF-alpha, IL-6, IL1-beta, resistin, leptin, adiponectin, glucose, insulin, HbA1c, lipid profile and transaminases are measured at the beginning and at the end of the period. Statistical analysis: t Student test; Friedman and Kruskal Wallis test are used. Variables are adjusted for: sex, age, baseline BMI and percentage weight change.

The purpose of this study is to determine the impact of consuming cocoa on blood glucose levels, glucose metabolism, and other markers of pre-diabetes in overweight and/or obese individuals. Our hypothesis is that consumption of cocoa improves insulin sensitivity and glucose metabolism in subjects at risk for developing type-2 diabetes.

The reasons for the epidemics of diabetes and prediabetes, and why individuals from certain populations suffer at higher rates are not well known. In the Pathobiology and Reversibility of Prediabetes in a Biracial Cohort (PROP-ABC) study, nearly 400 African Americans and Caucasians whose parents have type 2 diabetes will undergo repeated testing to determine what factors lead to the occurrence of prediabetes, and whether race still plays a major role in a setting where everyone being studied has one or both parents with diabetes. The PROP-ABC Study also will test the hypothesis that the ability of intensive lifestyle intervention to reverse prediabetes and return people's metabolism back to normal is dependent on how long people have had prediabetes.

The number of people diagnosed with Type 2 diabetes (T2DM) is increasing rapidly and about 2.9 million people in the UK currently have diabetes. There is increasing evidence suggesting that prolonged sedentary time may actually increase the risk of diabetes and other chronic diseases. Importantly, adults can meet public health guidelines on physical activity (150 minutes of moderate activity per week), but if they still sit for prolonged periods, their metabolic health is compromised. Going from sitting to standing and carrying out light-intensity activities (such as casual walking) may reduce diabetes risk. However, no one has investigated the effect of standing and walking on markers of cardio-metabolic markers in individuals with a high risk of T2DM. Therefore, the aim is to find out whether reducing the amount of time people spend sitting and replacing it with standing and light intensity activity (walking) reduces glucose, insulin and triglyceride levels, therefore reducing the risk of diabetes.

The rise in the prevalence of type 2 diabetes is related to recent lifestyle changes leading to a rise in obesity. Obesity is a risk factor for Impaired Glucose Tolerance (IGT) and diabetes. A type of fibre - fermentable carbohydrate - may help prevent diabetes in individuals with IGT by reducing appetite and food intake, and improving insulin sensitivity. Although fermentable carbohydrate is not absorbed in the small intestine it is full fermented by the colonic bacteria. The fermentation of this carbohydrate produces short chain fatty acids which act on specific G protein coupled receptors (GPR41/43) in the intestine to release GLP-1 and PYY. GLP-1 and PYY are hormones which act on appetite centres in the brain to decrease appetite. GLP-1 incretin effects and possible effect of the beta cell will increase insulin sensitivity. Short chain fatty acids also suppress the release of free fatty acids from adipocytes. Lower levels of free fatty acids in insulin resistant subject's leads to improved insulin sensitivity. This body of work will examine the effect of fermentable carbohydrate on appetite, weight loss, blood glucose control which will give an indication of the possibility of fermentable carbohydrate to prevent type 2 diabetes in this at-risk group.

Objective of this study is to determine the safety and efficacy of administration of herbal supplements (Salacia leaf extract, Salacia root extract and Sesame seed extract) for 6 weeks in the management of prediabetes and mild to moderate hyperlipidemia.

The primary aim of this study is to evaluate the effect of exenatide on daily glycemic excursions obtained by continuous glucose monitoring system (CGMS). The CGMS summary parameters that we are most interested in include: The percent of glucose values above 140 mg/dl and/or AUC of glucose values above 140 mg/dl AUC of glucose values over 100 mg/dl during three days Maximal meal-related glucose excursions Three-day mean glucose (including low readings - below 100 mg/dl) Secondary Study Endpoints: Secondary endpoints will include: glucose tolerance status as assessed by OGTT Vascular function scores as assessed by PAT, FMD and step test. Biochemical markers of vascular health, including inflammatory markers, markers of oxidative stress and microalbuminuria. Changes in BMI
