Active clinical trials for "Insulin Resistance"

The study is an open-label 8-week adjunctive trial of pioglitazone for the acute relief of bipolar depression comorbid with metabolic syndrome/insulin resistance. Subjects who experience a partial or full response will have the option of continuing in an acute continuation phase lasting up to 12 weeks. The extension phase will allow assessment of the safety and tolerability of pioglitazone during the acute continuation period.

This is a phase II, open label, randomized-controlled pilot study designed to study both the efficacy and safety of salsalate in decreasing endothelial cell dysfunction, systemic inflammation, and insulin resistance in HIV-infected adults. The investigators hypothesis is that salsalate will reduce inflammation and therefore endothelial cell activation and insulin resistance. The sample size will be 40, with an equal number of people being randomized to one of two groups. The first arm will be randomized to salsalate therapy. The second arm will act as a control group. The study duration will be 13 weeks.

Primary objective: To identify a biomarker or biomarker-set for the adverse metabolic effects of various doses of prednisolone treatment. Secondary objectives: To describe the PK of prednisolone and PD of a series of biomarkers. To identify biomarkers that reflect side effects of prednisolone. To elucidate part of the mechanisms by which prednisolone induces metabolic changes.

The current study is initiated in order to assess the impact of a PD solution containing L-carnitine on insulin sensitivity measured by a hyperinsulinemic euglycemic clamp.

Chronic hepatitis C (CHC) infection affects approximately 1 in 100 Canadians. Untreated, CHC has significant long-term consequences including cirrhosis, liver cancer and liver failure. CHC is intrinsically linked to both obesity and insulin resistance (IR) or "pre-diabetes", their co-existence worsens overall health outcomes. We have demonstrated that obesity (BMI ≥30kg/m2) is over twice as common amongst patients with CHC (28.8%) compared with the general Canadian population. Obesity superimposed on CHC reduces the success of antiviral treatment and promotes liver scarring (hepatic fibrosis), fatty liver (steatosis) and increases the risk of liver cancer. Both CHC and obesity contribute to IR putting these patients at risk of type 2 diabetes. IR, like obesity in CHC, reduces antiviral success rates. We have shown that diabetics are at higher risk of developing liver cancer compared with non-diabetics. It is therefore timely to address lifestyle modification to delay the onset of diabetes. We will examine the impact of a multidisciplinary lifestyle program on the insulin resistance in 52 obese "pre-diabetic" patients with current or past CHC. The 24 week program comprises an individualized nutritional and exercise plan supported by behavior modification counseling. Through gaining a better understanding of links between obesity, insulin resistance and hepatitis C infection we hope to delay the onset of diabetes and reduce the likelihood of all their untoward effects on the liver.

102 late- life adults at risk for developing type 2 diabetes mellitus, will be randomized to one of three interventions designed to improve insulin sensitivity thereby potentially preventing future progression of type 2 diabetes. The investigators predict that insulin sensitivity will improve equally following either weight loss or exercise, while there will be additive effects from combined intervention. The investigators hypothesize that weight loss will decrease intermuscular adipose tissue, intramyocellular lipid, and visceral abdominal adipose tissue.

The purpose of this study is to evaluate the impact of vitamin D3 supplementation on the insulin resistance in non-diabetic patients with chronic kidney disease (CKD) stages 3-4, vitamin D deficiency/insufficiency and elevated fasting serum insulin levels.

Whole grain intake beneficially affects body weight, body fat and glucose metabolism, and the investigators' previous work has shown that a high whole grain intake significantly reduced body fat in the abdominal region as measured by dual energy X-ray absorptiometry (DEXA) compared to a refined grain intake. Additional research is needed with regard to the mechanisms by which whole grains may affect visceral adiposity and the adipokines, which have been associated with risk for insulin resistance and type 2 diabetes. Therefore the proposed study aims to address these issues and in addition, includes exploratory work with adipocytes in cell culture to evaluate the effects of whole grains on adipocyte function. Hypothesis: There will be a greater reduction in visceral adiposity, indicators of insulin resistance (HOMA score), improvement in inflammatory status and improvement in adipokine levels after six weeks of a weight stable period and after six weeks of weight loss in subjects consuming 6-9 servings compared to 0 servings of whole grains per day.

The objective of this study is to determine the effect of 8 weeks of treatment with colesevelam HCl 3.75 g once daily with the evening meal on ß-cell function by evaluating the acute insulin response (AIRg) to an intravenous glucose load in subjects with prediabetes (impaired fasting glucose).

The aim of this study is to determine the effect of DMMET-01 on insulin sensitivity by Glucose CLAMP technique in Mexican type 2 diabetes patients, after 2 months of treatment.
