Active clinical trials for "Insulin Resistance"

This is a Phase 3b/4, prospective, open-label, randomized, multicenter study of peginterferon alfa-2b plus ribavirin in participants with chronic hepatitis C, genotype 1. The study consists of two parts: (1) a noninterventional arm (HOMA IR <= 2) and (2) an interventional arm (HOMA IR > 2), where HOMA IR is the insulin resistance index for the participants calculated by fasting insulin (uU/mL) x [fasting glucose (mmol/L)/22.5]. Participants in the noninterventional arm are treated according to the European labeling and response rates are evaluated at Month 1 (optional), 3, 6, 12, and follow up. Participants in the interventional arm are treated with PEG-Intron 1.5 ug/kg (subcutaneous) once weekly plus weight-based REBETOL 800-1400 mg (oral capsules) daily for a variable period depending on their response at Week 12: (1) HCV-RNA positive with < 2-log drop in viral load, treatment will be discontinued; (2) HCV-RNA positive with >= 2-log drop in viral load; participants will be randomized (1:1) to Group A (stop treatment at Week 48) or Group B (stop treatment at Week 72); and (3) HCV-RNA negative, treatment will be changed to be according to the European labeling and response rates will be evaluated at Month 6, 12, and follow up. All participants will go on with their treatment after Week 12 until the results of the HCV polymerase chain reaction (PCR) are available (maximum of 4 weeks).

Double-blind, randomized placebo-controlled study in type 2 diabetes and dyslipidemic patients.Patients will be randomized to one of four treatment arms for 16 weeks: placebo, fenofibrate, metformin, or metformin and fenofibrate combination.

The investigators are studying the pathophysiologic links between obesity, insulin resistance (IR), adipose tissue infection, and post-acute sequelae of COVID-19 (PASC). This study looks at whether adipose (fat) tissue contributes to PASC by driving chronic inflammation or by serving as a reservoir for SARS-CoV-2 persistence. The results will not only determine whether obesity and IR are risk factors for PASC, but will also define fundamental biology that sets the stage for the investigation of novel or existing therapies that target the causal pathways identified.

The proposed study is designed to test the hypothesis that in human obesity, the balance of pro- and anti-inflammatory T cells in fat tissue is in fact related to macrophage phenotype and insulin resistance, and how it is related. This study is needed to confirm whether conclusions based on studies of visceral adipose tissue in mice are indeed applicable to humans. We also want to determine the relationship between insulin resistance/hyperinsulinemia and ability to lose weight in obese individuals.

Glucocorticoids are known to cause an increase in insulin resistance, leading to hyperglycemia, in both diabetic and non-diabetic patients. In both the inpatient and outpatient setting, steroids are used for their anti-inflammatory property to treat a variety of conditions. There is a paucity of information regarding the best way to treat steroid-induced hyperglycemia. In this study we will compare (1) the addition of NPH insulin, an intermediate-acting insulin, given at the time of steroid administration to the patient's standard basal/bolus insulin to (2) modification of the standard basal-bolus insulin regimen which will consist primarily increasing the prandial doses at lunch and supper in order to determine which regimen is superior for glycemic control.

Assessing sleep and circadian health in severely obese adolescents undergoing bariatric surgery and examine relation to health outcomes including insulin sensitivity and percent weight loss to date at 1-year and evaluate the impact of sleep extension on health outcomes in this population.

Renal denervation has recently shown to improve glucose metabolism and insulin sensitivity in addition to reducing blood pressure. The mechanisms are however unclear. The investigators hypothesize that renal denervation alters adipose tissue function by reduced sympathetic outflow, measured by fat biopsies and markers of inflammation and insulin sensitivity. 15 clinical patients undergoing renal denervation are recruited to the study investigating anthropometry, peripheral blood samples, body composition, heart rate variability and subcutaneous fat biopsies at baseline and 6 months after renal denervation.

A number of studies have shown that short duration, high intensity interval training can improve health-related outcomes, such as insulin sensitivity and cardiorespiratory fitness. However, these often use specialized equipment, such as cycle ergometers, which makes it difficult to roll these interventions out for wide-scale use in the general population. This study aims evaluate the effects of a high intensity shuttle running intervention on insulin sensitivity, fitness and related cardiometabolic risk factors in men who are currently inactive. Participants will be randomized into intervention (4 weeks of shuttle running) and control groups. We hypothesize that the shuttle running programme will result in improved insulin sensitivity, fitness and increased fat oxidation at rest compared with the control group.

The goal of this study is to evaluate the efficacy of metformin on insulin sensitivity and vascular endothelial function with respect to gut microbiota and metabolome in women with established insulin resistance and its tolerance after 12 weeks of probiotic therapy. The hypothesis is probiotic therapy in women with established insulin resistance undergoing metformin treatment increases the drug's efficacy to improve insulin sensitivity and intestinal endothelial function, and reduces gastrointestinal side effects. Study participants will be randomly assigned to 2 groups, taking a probiotic (GS) or a placebo (GP). The randomization scheme will be computer-generated using permuted blocks of block size 4.

Policystic ovary syndrome is the most common endocrinopthy during reproductive period. One of the factors implicated in the pathogenesis is insulin resistance. Asprosin, which is secreted from white adipose tissue is a new candidate for insulin resistance. Myoinositol is known to reduce insulin resistance in PCOS patients. The effect of myoinsitol on serum asprosin levels is unknown yet. This study aimed to evaluate the effect of myoinositol on serum asprosin levels in PCOS patients.
