Active clinical trials for "Insulin Resistance"

Hyperinsulinemia and insulin resistance play a key role in the pathogenesis of polycystic ovary syndrome (PCOS). Insulin resistance is significantly associated with the long-term risks of metabolic syndrome and cardiovascular disease. Acupuncture with electrical stimulation has in rats with dihydrotestosterone (DHT)-induced PCOS been shown to improve insulin sensitivity. Whether these findings can be translated into women with PCOS has not been investigated. Therefore, this study aims to evaluate whether acupuncture improves insulin sensitivity, ovulation rate and quality of life in women with PCOS. Our hypothesis is that acupuncture with combined manual and low-frequency electrical stimulation of the needles improves insulin resistance, induces ovulation and improves quality of life.

Insulin resistance is a key reaction to surgery and trauma and reflects the degree of metabolic stress. With greater degree of insulin resistance the development of complications increase, in particular infectious complications. The aim of this study is to determine if robotic assisted total laparoscopic hysterectomy induces less insulin resistance compared to abdominal hysterectomy. Insulin resistance is measured by the hyperinsulinemic normoglycemic clamp method. In addition inflammatory factors and clinical recovery will be measured.

Ultra-low-dose oral E2/D will have more beneficial effects than trans-dermal HRT on lipids and insulin resistance in postmenopausal women, whilst adverse effects on coagulation will be avoided.

Growth hormone treatment improves body fat distribution but also causes insulin resistance. Scientists have recently linked insulin resistance with special stores of fat in the muscles, which can be measured by magnetic resonance imaging (MRI). The researchers hypothesize that growth hormone will paradoxically reverse the linkage between muscle fat stores and insulin resistance. To assess this association and to investigate the cause(s), the researchers will measure muscle fat stores during growth hormone treatment. Other parameters linked to insulin resistance (glucose tolerance, blood markers, and body composition) will also be assessed. This study may lead to improved strategies for monitoring growth hormone therapy.

Approximately 20 million people in the United States have some form of kidney failure. People with kidney failure have an increased chance of having low levels of high density lipid (HDL), so called "good cholesterol." Patients who are overweight or obese also have low levels of HDL. The investigators are trying to find out whether causes of low HDL are the same in people who are overweight and in patients with kidney failure so that in the future doctors can better treat low HDL cholesterol levels. People with low levels of HDL are more likely to have heart attacks and strokes and are more likely to lose kidney function. This study hope to learn more about how kidney failure causes low HDL cholesterol levels.

The aim of the study is to investigate the treatment response of metformin, Peg-IFN and ribavirin combination therapy for chronic hepatitis C virus (HCV).

In this explorative randomized clinical study, the investigators aim to study metabolic, cellular, and molecular changes that occur during weight loss in obese subjects with and without type 2 diabetes. Using novel "imiomics" (imaging technique using PET/MR bioinformatics) analyses to examine possible metabolic differences between energy restricted diet and gastric by-pass surgery on whole-body and tissue specific insulin sensitivity, glucose tolerance, metabolite and protein profiles, fatty acid metabolism, ectopic fat content, and gene expression in adipose tissue. This study aims to identify novel biomarkers and drug targets for type 2 diabetes as well as validate promising and established biomarkers in an interventional model for improved glucose metabolism.

The main pathogenesis of type 2 diabetes mellitus is insulin resistance and insufficient secretion of insulin by pancreatic beta cells. SGLT2 (sodium-glucose synergistic transporter 2) inhibitor is a kind of newly developed hypoglycemic medicine, which increases urinary glucose excretion and lowers blood glucose in an insulin-independent manner. The mechanisms of its effects on insulin resistance, insulin secretion by pancreatic beta cells and glucagon secretion by pancreatic alpha cells, are not well studied in domestic and foreign, and there is no unified conclusion. A few studies concerning SGLT2 inhibitors have observed that insulin resistance and islet beta cell secretion function can be improved by the improvement of glucotoxicity and lipotoxicity, but its effect on pancreatic alpha cell function to increase glucagon level, thereby increasing liver glucose output, may be one of the mechanisms of its side effects. In this study, patients with type 2 diabetes mellitus were treated with three domestic listed SGLT2 inhibitors (dapagliflozin, empagliflozin and canagliflozin) for one week, which were expected to improve the glucotoxicity, but excluding the effects on lipotoxicity and body weight, to observe the changes of islet beta cell and alpha cell function and insulin sensitivity. Three different SGLT2 inhibitors were used in order to make clear whether this effect is the unique effect of different structure of drugs or the similar effect of this kind of drugs.

Aim of this study to evaluate the effects of extra virgin olive oil on glycemic control ,insulin resistance and insulin secretion in patients with Type 2 diabetics.

Assessment of Gastric Bypass combined with Vertical Sleeve Gastrectomy as primary treatment for patients with severe clinical obesity. Average percentage of total weight loss and percentage excess weight loss will be computed at 6 months, one year and then annually. Comorbid conditions, quality of life measures, appetite and satiety measures and adverse events will be tracked.
