View clinical trials related to Insulin Resistance.
Filter by:Metabolic syndrome (MS) is a clinical entity that includes several disorders that predispose to imbalance in lipid metabolism: hypertension, insulin resistance, hypertriglyceridemia, obesity and low levels of high density lipoprotein. The SM itself has a great impact on morbidity and mortality and is also related to increased cerebrovascular risk and Diabetes Mellitus 2 (DM2). In Colombia, DM2 is one of the 10 leading causes of illness and death in people over 45 years. It is accepted that insulin resistance is a stage that precedes the onset of DM2, but there are few alternatives to reverse it or prevent its progression to diabetes. The control of insulin resistance requires increased physical activity, reduced body weight and changes in eating patterns, measures that are not easily adopted in modern Western society. There is evidence of the effect of chocolate consumption on increasing insulin sensitivity in both hypertensive diabetic patients as well as in normal individuals, apparently because of the ability of cocoa polyphenols to increase the bioavailability of nitric oxide, Formation of reactive species of oxine, optimizing carbohydrate metabolism and modulating insulin-related cellular signaling events. A prospective, double-blind, placebo-controlled, double-blind clinical trial evaluating the effect of 50 g of chocolate with 70% cocoa solids, which contributes at least 430 mg of polyphenols, is conducted for 8 weeks in The reduction of insulin resistance defined by the reduction of the HOMA-IR index. In addition, there was an increase in arterial reactivity in non-diabetic individuals with central obesity and insulin resistance. Likewise, to infer the effect of this food intervention in the modification of the total cardiometabolic risk of the participants.
This study intends to examine the effect of a commercially available nutritional supplement, Beta-hydroxy-beta-methylbutyrate(HMB) on whole-body responses to a sugar load.
The importance of Aldosterone for endothelial function and Insulin resistance observed within patients with type 2 diabetes
Physical inactivity results in reductions in glucose tolerance and less sensitivity to insulin. If this inactivity lasts long enough it can result in insulin resistance and type 2 diabetes. A high protein diet can reduce elevated glucose levels in individuals with type 2 diabetes. Thus the investigators are interested in establishing if during a period of inactivity if a diet modification can minimize the glucose changes normally observed with inactivity. The objective of this project is to determine if short-term high protein (HP) feeding protects against the changes in glucose levels normally observed with physical inactivity. The investigators will also examine measures of blood vessel function, blood lipid and blood pressure. Twelve subjects will complete two 10 day study periods of reduced physical activity and will be studied before and after each of these study periods. For their testing subjects will have the following measurements: postprandial glucose responses to a mixed meal, 24 h free living blood pressure control during acute physical inactivity, blood lipids, changes in body composition, changes in circadian rhythm using skin temperature (ibutton), measurement of aerobic capacity (VO2 max), blood vessel responsiveness (flow mediated dilation -FMD) and changes in free living glucose levels (continuous glucose monitoring system (CGMS). Subjects will complete two conditions (high protein -HP vs normal protein - NP diets) in a randomized cross-over design. In the inactive phase subjects will reduce there steps to <5,000 steps/d while consuming either a HP or NP diet. Completion of the study will take 8-10 weeks.
This proposal will test the hypothesis that chronic treatment with sildenafil with and without the use of nitric oxide substrate, L-arginine, protects against fatty acid induced impairment of endothelial function, improves insulin-stimulated microvascular recruitment, insulin sensitivity and glucose uptake in CD36 rs3211938 G-allele carriers.
Pioglitazone, a medication of thiazolidinedione group, is capable of triggering the peroxisome proliferator-activated receptors (PPAR-γ). Activation of receptor PPAR-γ regulates carbohydrate and lipid metabolism, immune and inflammatory responses in heart tissues. Our aim will to study the effect of pioglitazone on insulin resistance, the clinical course of atherosclerosis and coronary heart disease (CHD). The study will include 43 patients with coronary artery disease. Patients will be divided into the study group - 20 patients, in whom pioglitazone will be included in the combined therapy at a dose of 15 mg 1 time per day in the morning, and the control group - 23 patients receiving standard complex drug therapy over 6 months. Patients will be underwent clinical examination, ultrasound of neck vessels, study of carbohydrate and lipid metabolism. The end primary points of the study will be the onset of death due to myocardial infarction, coronary revascularization procedures (coronary artery bypass grafting (CABG) or percutaneous coronary intervention (PCI)), or hospitalization for acute coronary syndrome (ACS) or unstable angina (UA). Predefined secondary end points included carotic atherosclerotic leisure (carotic intima-media thickness, diameter of stenosis, presents of atherosclerotic plaque), systemic inflammation level (the level of C reactive protein), lipid metabolism (levels of serum total cholesterol, triglycerides, high and low density lipoproteins), level of insulin resistance ( oral glucose tolerance test, blood glucose).
This study aims to show whether the hyperglycaemic phases following a treatment with glucocorticoids, as well as blood measurements correlated to high blood glucose levels and insulin resistance, vary significantly between patients with and without gestational diabetes mellitus.
The purpose of this study is to see what effect skipping breakfast versus consuming breakfast has on cognitive performance and the hormones responsible for glucose homeostasis in lean and obese adolescent males. The subjects will be tested on their ability to maintain attention when given several tasks called continuous temporal expectancy tasks (CTET) and electrophysiological signals using electroencephalogram (EEG) will be monitored. These two study groups will be randomized to one of two orders: (A,B) or (B,A) where A = breakfast intervention and B = no breakfast. There will be a washout period of 7 days in between study visits.
Type 2 diabetes is a worldwide epidemic disease, and preventive strategies are needed to face this health problem. The goal of this clinical trial is to evaluate the effect of linagliptin + metformin vs metformin alone on physiopathological parameters, such as glucose metabolism, insulin resistance, insulin secretion and pancreatic beta cell function in patients with impaired fasting glucose plus impaired glucose tolerance, during 24 months.
The incidence of atopic dermatitis and type 2 diabetes, respectively, has increased over many years. Novel research shows an association between the two conditions. While this relationship at least in theory can be explained by lifestyle factors, there is reason to believe that other pathophysiological mechanisms are involved. Hence, our hypothesis is that patients with atopic dermatitis are insulin resistant due to their chronic inflammatory state. Insulin resistance might play an unknown part in the increased frequency of type 2 diabetes among patients with atopic dermatitis. In the present project, the investigators aim to measure insulin sensitivity by means of the 'golden standard' hyperinsulinaemic euglycaemic clamp in patients suffering from atopic dermatitis compared to a healthy control group (matched case-control study). The project is a close collaboration between The Department of Dermatology and Allergy and Center for Diabetes Research at Gentofte Hospital.
