Active clinical trials for "Insulin Resistance"

The purpose of this study is to investigate the effects of a combined training programme on insulin resistance, exercise tolerance, muscle strength, body composition and cardiac function in chronic heart failure patients. It is assumed that the above mentioned clinical parameters will improve due to physical exercise.

The aim of the study is to evaluate the effect of metformin on myocardial function, insulin resistance and selected metabolic markers in patients with type 2 diabetes and heart failure (HF+DM+) in a cross-over, randomized, placebo controlled trial. Hypothesis: Metformin treatment in HF+DM+ group will lead to better myocardial function and load tolerance in comparison to placebo. The degree of improvement will be linked to selected metabolic parameters.

Renal sympathetic nerves contribute to development of hypertension. Sympathetic overactivity also induces insulin resistance and it could therefore be assumed that a renal denervation might improve insulin sensitivity. Studies have shown that glucose metabolism is improved in patients with treatment resistant essential hypertension both 1 and 3 months after renal denervation compared to a control group with treatment resistant essential hypertension. Fasting glucose, insulin and C-peptide decreased significantly as did insulin resistance assessed by HOMA-IR. The investigators wish to investigate the effect of renal denervation on insulin sensitivity using the gold standard - the hyperinsulinemic euglycemic clamp and to investigate the degree of insulin resistance in muscle, liver and adipose tissue.

The purpose of this study is to evaluate the effect of exercise on Insulin Resistance (IR) in subjects who do not routinely exercise and who are at risk of developing diabetes (prediabetes). It is estimated that approximately 30-90 people will participate in this study at three study sites in the United States and United Kingdom.

The role of individual leukocyte populations in type 2 diabetes (T2D) and immunometabolism in general represent important gaps in knowledge to better understand the etiopathogenesis of T2D. Emerging evidence indicates that certain leukocyte populations serve as an important nexus of T2D-associated inflammation. This novel and innovative clinical trial will test the efficacy of a leukocyte-selective anti-inflammatory small drug as adjunctive therapy in improving insulin sensitivity in obese, insulin-resistant type 2 diabetic subjects. This trial also offers a first-in-kind opportunity to better understand the role of specific leukocyte populations in type 2 diabetes. The drug's clinical profile suggests that it will be well-tolerated with few, if any, side effects, and the existence of simple methods that can indirectly measure its activity in vivo

The importance of vitamin D (VitD) in the prevention and treatment of human health conditions has gained increased attention in recent years. As a result, medical providers of all categories are screening clinical VitD status frequently, yet become challenged with how to best advise patients regarding repletion of VitD status, i.e. which form of VitD replacement is most effective. It has been recognized that to achieve significant effects - serum concentrations >30ng/ml (75 nmol/ml) - it is necessary, as well as safe, to recommend substantially higher doses than were previously thought sufficient. These higher doses can be easily achieved orally. This clinical trial aims to compare absorption of three available forms of this fat-soluble vitamin, due to the potential differences in absorption of different preparations. High-quality powdered, chewable and lipid-emulsified VitD are readily available as supplements, yet these have not been systematically compared. This three-arm, randomized clinical trial will compare the difference in serum 25-hydroxycholecalciferol (25-OH)D concentration between the three arms at baseline and after random administration of one of the three VitD preparations for 12-weeks at a dosage of 10,000 IU VitD per day. The investigators hypothesize that the three forms of vitD will result in an equivalent increase in serum 25OHD.

Objectives: The investigators examined whether rosiglitazone, a thiazolidinedione (TZD), is beneficial for pre-diabetes mellitus (DM) adults with documented coronary artery disease (CAD). Background: Microvascular and macrovascular complications are common in type 2 DM. There is no evidence about the effects of TZDs, synthetic peroxisome proliferator-activated receptor (PPAR)-γ activators (insulin sensitizers and adipose transcriptional regulation and anti-inflammatory process activators) on pre-DM patients with documented CAD.

The purpose of this study is to evaluate efficacy of phlebotomy on insulin sensitivity as evaluated by euglycemic-hyperinsulinic clamp in insulin resistance-associated hepatic iron overload patients.

This study compared traditional concept of preoperative fasting before elective open colon surgery and preoperative treatment with carbohydrate oral drink in intention to improve postoperative stress response to surgical procedure. Hypothesis was: preoperative oral carbohydrate drink reduces postoperative insulin resistance, improves insulin sensitivity, reduces postoperative inflammatory response in terms of the value of Glasgow Prognostic Score (GPS) and IL-6, improves postoperative patient's subjective well-being and surgical clinical outcome.

Amla has demonstrated promising effects in the treatment of obesity, dyslipidemia, hypertension, insulin secretion, among others. The above mentioned findings show that Amla has an excellent potential for the prevention and treatment of metabolic syndrome.
