Active clinical trials for "Insulin Resistance"

Muscle strength helps determine a person's quality of life and functional independence. Patients with rheumatoid arthritis often suffer from muscle weakness and a pre-diabetic condition called insulin resistance. By doing this study, the investigators hope to learn why patients with rheumatoid arthritis (RA) suffer from muscle weakness.

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.

The purpose of this study is to determine insulin sensitivity in individuals that are lean normal glucose tolerant subjects after consumption of a normal low fat diet and after a high fat diet and to explore the effects of high fat consumption on the intestinal microbiome, and metabolic endotoxemia.( Aim 1 of the protocol, a separate record is available for Aim 2)

Vitamin D deficiency is extremely common in obese youth. In our obese population followed in the Endocrinology clinic at Children's Medical Center Dallas, vitamin D levels were inversely correlated with a measure of insulin resistance. We propose to show that correction of vitamin D levels in obese children and adolescents improves their insulin sensitivity. Obese youth presenting to the Center for Obesity and its Consequences on Health (COACH) clinic will be randomized to receive either the most recent Institute of Medicine (IOM) recommendations of minimum D3 dose of 600 IU/day (1), or receive higher doses of D3 such that the blood levels of vitamin D will be brought to a target level in either the low part or high part of the normal range. The goal is to determine if correction of vitamin D deficiency will improve insulin sensitivity in this group. Secondary goals include determining whether correction of vitamin D deficiency in obese adolescents and children results in less weight gain, and determining the amount of D3 required to correct vitamin D levels in this population. Our specific hypotheses are as follows: Hypothesis #1 Obese youth treated with Vitamin D3 who achieve low-normal 25-hydroxyvitamin D3 (OHD) levels (30-50 ng/mL) or high-normal 25-OHD levels (60-80 ng/mL) will have improved insulin resistance, as measured by Homeostatic Model Assessment of Insulin Resistance (HOMA-IR), compared to those individuals with deficient 25-OHD levels (< 30 ng/mL). Hypothesis #2 Subjects with a higher BMI will have higher Vitamin D dose requirements than current IOM recommendations of 600 IU/day and will take a longer period of time to reach target 25-OHD levels. Hypothesis #3 Subjects with normal 25-OHD levels will demonstrate less weight gain compared to subjects on the control arm.

The purpose of this study is to learn more about how U500 regular insulin can be effectively be used to treat type 2 diabetes. Most insulin treated patients with type 2 diabetes take U100 insulin, but if they require large doses (such as >150 units a day) they may experience pain at this site of injection and the absorption of the insulin is unpredictable, thereby leading to poor glucose control. To overcome these problems, doctors sometimes switch to a more concentrated form of insulin called U500 insulin. U500 is five times as concentrated as U100 insulin and therefore delivers an equivalent dose of insulin in much lesser volume. However, how to best use U-500 insulin is not certain. The investigators are not really sure how long a given dose is effective in patients who require large doses (>150 units of U100 insulin), so are not sure of how often the drug should be administered. In this study, the investigators will determine how effective two different doses of U-500 regular insulin (100 U and 200 U) are in lowering blood sugar and how long these two doses last. This information will help doctors develop better treatment plans for patients with type 2 diabetes.

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

Obesity is a chronic disease of multifactorial etiology that develops from the interaction of the influence of nutritive , metabolic , cellular and molecular psychological factors. Tadalafil is Is a drug inhibiting the enzyme phosphodiesterase-5 (PDE-5), responsible for inactivating the vasodilator nitric oxide. USING paragraph was mainly treat erectile dysfunction, and recently approved for the treatment of pulmonary hypertension , it is innovative because of its longer life means, provides efficacy after 36 hours and the highest selectivity. The aim of this study is to evaluate the effect of tadalafil on insulin sensitivity and insulin secretion in obese men. The investigators hypothesis is that the administration of tadalafil improve the insulin sensitivity and insulin secretion in obese men.

The investigators designed this randomized double blind (patients/ assessor) clinical trial to compare the therapeutic effects of Metformin monotherapy with Metformin and acupuncture combined therapy on weight loss and insulin sensitivity among overweight/obese type 2 diabetes mellitus (T2DM) patients. We compared the inflammatory markers, lipid profiles, and adipokines in overweight/obese T2DM patients receiving the combined therapy to those receiving the Metformin monotherapy, to understand whether acupuncture plus Metformin is a better approach then Metformin only on treating diabetes.

In this study, consecutive patients with cryptogenic cirrhosis (NASH-related cirrhosis), coming to ILBS (Institute of Liver & Biliary Sciences) OPD (Out patient Department) or getting admitted in the ward will be enrolled on fulfillment of inclusion/exclusion criteria and consent of the patient. These patients will be randomised to either metformin arm or conventional treatment arm. After enrollment these subjects will be monitored every three monthly for total of 12 months or till the primary endpoint is achieved. At the end of the study, outcome will be measured appropriately.

HMG co-A reductase inhibitors, commonly called statins, are an effective treatment for dyslipidemia and atherosclerotic heart disease with proven mortality benefit. While the lipid-lowering effects of statins are well-known, other metabolic effects, including effects on glucose tolerance and ectopic fat distribution, are less completely understood. Recent studies have shown that some statins may increase the risk of diabetes. Further, research has suggested that statins may have some benefit in nonalcoholic fatty liver disease (NAFLD), a condition associated with obesity that includes increased fat in the liver (steatosis) and, in some cases, inflammation and hepatocellular damage (steatohepatitis). Pitavastatin, approved by the United States Food and Drug Administration (FDA) in 2009, is the most recent statin to enter the market. Unlike most statins, pitavastatin is not primarily metabolized through cytochrome P450 (CYP450), and thus has reduced potential for interactions with other medications that are metabolized by CYP450. Previous studies have suggested that pitavastatin may be neutral to glucose homeostasis and may improve hepatic lipid. Neither of these effects has been proven definitively, however, and the current proposal aims to characterize in detail the effects of pitavastatin on glucose homeostasis, hepatic steatosis, and steatohepatitis.
