Active clinical trials for "Insulin Resistance"

Individuals with pre-diabetes or diabetes would benefit from low impact methods that would improve their insulin sensitivity and aid in maintaining glucose homeostasis. Physical activity helps the body decrease its insulin resistance and burn excess sugar. Many diabetics also suffer from obesity and specific forms or durations of physical exercise may not be viable options for these individuals. Determining whether short bursts of moderate exercise improve blood glucose levels in healthy humans may identify a further method for diabetics to improve their glucose homeostasis. The aim of this study is to determine the most effective moderate exercise that can be completed in 3 minutes and its effectiveness on improving glucose handling, in response to a single day of standardized high-fat and high-carbohydrate feeding in comparison to periods of prolonged sitting.

The objective of this study is to investigate the effect ofRutin and Vitamin C combination in comparison with vitamin C alone on the oxidative and antioxidative status , insulin resistance and lipid profile in type 2 diabetic patients.

Probiotics have beneficial effect on obesity related disorders in animal models. Despite a large number of animal data, randomized placebo-controlled trials (RCT) concluded that probiotics have a moderate effect on glycemic control-related parameters. However, effect of probiotics on insulin resistance are inconsistent. In this double-blind single center RCT, effect of alive multistrain probiotic vs. placebo on insulin resistance in type 2 diabetes patient will be assessed.

This randomized, controlled trial aims to elucidate the mechanisms by which a plant-based dietary intervention causes weight loss. Using a low-fat, plant-based diet for 16 weeks, along with an untreated control for comparison, the study will measure changes in body weight, body composition, intramyocellular and/or intrahepatocellular lipid, and changes in association to body weight.

The purpose of this study is to evaluate the effects of semaglutide on intra-hepatic triglyceride (IHTG) content in people living with HIV (PLWH), central adiposity, insulin resistance or pre-diabetes, and hepatic steatosis.

Diabetes mellitus type 2 (T2D) is characterized by insulin resistance of liver and skeletal muscle, which is at least partly due to impaired muscle mitochondrial function. Long-term HBO therapy, as applied for treating the diabetic foot syndrome, has been shown to improve blood glucose concentrations. To study the underlying mechanisms, we want to examin the short-term effect of HBO treatment on insulin sensitivity and mitochondrial oxidative capacity and production of reactive oxygen species (ROS) in a randomized, double blinded, placebo-controlled cross-over trial.

The obesity epidemic calls for new therapeutic opportunities to prevent and treat obesity and its comorbidities amongst which are insulin resistance and cardiovascular diseases. Recent evidence suggests that tissue oxygenation plays an important role in cardiometabolic health. Remarkably, individuals residing at high altitude (hypobaric hypoxia) are less prone to develop type 2 diabetes mellitus as compared to individuals living at sea-level (normobaric normoxia). Furthermore, there is evidence to suggest that normobaric hypoxia exposure may improve glucose homeostasis and insulin sensitivity in both rodents and humans. The level of physical activity is an important determinant of insulin sensitivity and glucose homeostasis. It is well established that performing physical activity improves glucose uptake in the short term, and glycemic control in the long term. Interestingly, recent studies have demonstrated that an acute bout of exercise under hypoxic conditions (inhalation of air containing less oxygen) may lead to a more pronounced improvement in plasma glucose concentrations and/or insulin sensitivity as compared to normoxic exercise. However, the effects of repeated hypoxic exercise bouts on glucose profile throughout the day (i.e. 24h continuous glucose monitoring) remain elusive. In the present randomized, placebo-controlled, single-blind, cross-over study study, the investigators will investigate the effects of exercise under mild normobaric hypoxic conditions (FiO2, 15%) for 4 consecutive days (2 x 30-min cycling session at 50% WMAX) on postprandial substrate metabolism and 24h-glucose level in overweight/obese subjects with impaired glucose tolerance. The investigators hypothesize that 4 consecutive days of exposure to mild hypoxia while performing moderate intensity exercise improves glucose homeostasis in overweight and obese individuals with impaired glucose homeostasis.

Probiotics are defined as live microorganisms that, when administered in adequate amounts, confer a health benefit on the host. Omega-3 fatty acids belong to the family of polyunsaturated fatty acids. They are known to exert a strong positive influence on metabolism and inflammation. The data from animal studies suggested that both probiotics and omega-3 can affect body weight, influence on glucose and fat metabolism, improve insulin sensitivity and reduce chronic systemic inflammation. In respect to experimental data, the current study aim was to provide double-blind single center RCT, for study the efficacy of co-administration of probiotic with omega-3 vs. placebo in type 2 diabetes patient

To compare the effect of insulin sensitizing drugs (metformin and rosiglitazone) over glucose homeostasis (GH) in no diabetic metabolic syndrome individuals. A randomized blinded clinical trial did in patients with metabolic syndrome (n=30), without diabetes. Prior to detailed information and signature of informed consent by patients were done three treatment groups by randomized technique; a) Placebo, b) Metformin (850 mg/day), c) Rosiglitazone (4 mg/day), treatment was administered for 8 weeks. GH was measured before and after treatment using oral glucose tolerance test (OGTT), and IR-index (Homeostatic Model). Determination was performed on weight, size, body mass index, plicometry, blood pressure, fasting glucose levels, triglycerides, HDL-cholesterol and insulin.

There is currently no reliable, diagnostic tests of insulin resistance other than the hyperinsulinemic euglycemic clamp which, due to its constraints and cost, is reserved for research. The insulin-Regulated aminopeptidase (IRAP) protein is a direct marker of insulin-dependent glucose cell capture and thus it blood concentration seems to be a good diagnostic test of insulin resistance. The purpose of this study is to assess a plasma essay of IRAP protein for evaluation of insulin resistance during an oral glucose tolerance test (OGTT).
