Filter by:24 children (12 African-American, Hispanic, or American Indian, 12 Caucasian) previously diagnosed with type 1 diabetes mellitus will participate in this pilot study to evaluate the presence of hepatic and peripheral insulin resistance. The investigators will use this pilot information to test the hypothesis that insulin resistance occurs in some children with type 1 DM, is secondary to underlying risk factors, and is responsible for increased insulin needs. Methods will include a "step-up" hyperinsulinemic euglycemic clamp and infusion of the stable isotope 6,6-[2H2]-glucose. Patient and parent interviews will be conducted to gather information about nutritional intake, ethnicity, family history, and socioeconomic status. The investigators will also measure inflammatory cytokines and free fatty acids to determine whether they are associated with differences in insulin resistance among type 1 diabetes mellitus patients.
The hypothesis is that GHRP-3 will exert beneficial effects on endothelial function and insulin resistance in older men and women via hormonal (GH, IGF-I, IGFBP-3,-1, insulin) and non-hormonal actions (anti-inflammatory).
The primary aim of this study is to evaluate the effect of exenatide on daily glycemic excursions obtained by continuous glucose monitoring system (CGMS). The CGMS summary parameters that we are most interested in include: - The percent of glucose values above 140 mg/dl and/or AUC of glucose values above 140 mg/dl - AUC of glucose values over 100 mg/dl during three days - Maximal meal-related glucose excursions - Three-day mean glucose (including low readings - below 100 mg/dl) Secondary Study Endpoints: Secondary endpoints will include: - glucose tolerance status as assessed by OGTT - Vascular function scores as assessed by PAT, FMD and step test. - Biochemical markers of vascular health, including inflammatory markers, markers of oxidative stress and microalbuminuria. - Changes in BMI
The purpose of this study is to perform a randomized, controlled clinical trial to investigate if the phosphate binder sevelamer can improve insulin resistance and glucose handling in patients receiving maintenance hemodialysis.
The primary objective of this study is to examine the effects of four months of pioglitazone vs. metformin treatment on HDL cholesterol, triglycerides, blood pressure, insulin resistance, endothelial function, arterial stiffness, adipokines, oxidative stress, and blood biomarkers of endothelial activation in obese insulin resistant children. 30 obese children with elevated fasting insulin levels will be randomly assigned to pioglitazone or metformin for 16 weeks. Change in clinical variables over the 16-week study period will be compared between groups.
The current study is initiated in order to assess the impact of a PD solution containing L-carnitine on insulin sensitivity evaluated by measuring insulin requirement.
Major burn injury causes significant insulin resistance on glucose and protein metabolism that persists for up to 6 months after the acute injury This project proposes to answer the following questions: 1. Will fenofibrate given to burn patients with insulin resistance restore their insulin sensitivity? 2. What is the relationship between mitochondrial dysfunction in muscle tissue as the causative mechanism of burn related insulin resistance? 3. To what extent will the restored insulin sensitivity affect glucose and protein metabolism in muscle, regenerating wounds and the liver, i.e. ameliorate burn related hyperglycemia and protein catabolism?
Normoglycemia is important for the outcome of surgical and medical conditions. Insulin infusions have been studied to achieve normoglycemia during these circumstances and have proved to be useful. Insulin given by subcutaneous injections has longer duration compared to intravenous given insulin which makes it more difficult to control. The hypothesis behind the trial is the concept that insulin infusion is more effective in reaching normoglycemia in diabetic subjects during foot ulcer infection and surgical wound infection. - The study evaluates a target controlled insulin infusion or conventional therapy as antidiabetic treatment during foot ulcer infection and surgical wound infection. - Secondary efficacy parameter will be hospital stay, laboratories for inflammation and oxidative stress.
The purpose of this study is to investigate the effects of chronic elevated levels of Prolactin on metabolism and insulin sensitivity by studying patients with hyperprolactinemia before and after treatment.
Sirtuin activators may prove useful in treating age-related diseases and extending lifespan in humans. Resveratrol (RSV), a polyphenol found in red wine, has been shown in vitro to enhance SIRT1 activity. RSV is associated with some of the beneficial effects of red wine or the "French Paradox". Recently RSV has been associated with increasing lifespan in mice on a high calorie diet and improved metabolic profile and activity levels. The effect of this small molecule in humans is unknown. Preclinical observations suggest that RSV is safe and has enormous potential in the treatment of obesity and insulin resistance in humans. This pilot study will examine the effect of RSV on improving the metabolic profile of adults with insulin resistance. Specifically, this randomized double blind placebo controlled study will examine the effects of 4 weeks of supplementation with RSV 5.0 grams daily, compared to placebo control (PC) on the metabolic profile of 36 men and women over the age of 50 with insulin resistance (IR) consuming a typical western diet consisting of at least 40% calories from fat.
