Filter by:North American blacks tend to have low blood levels of vitamin D because pigmentation blocks vitamin D production in the skin. They also have higher rates of developing type 2 diabetes and higher rates of complications from the disease compared with whites. Although there is compelling evidence that adequate vitamin D may reduce the risk for type 2 diabetes in whites, recent evidence from a national survey demonstrated an association of vitamin D with diabetes in whites but not in blacks. However, the central hypothesis of this study is that providing enough supplemental vitamin D to blacks (raising their blood levels higher than that of most participants in the survey) will improve blood measures related to diabetes risk. The proposed study is a 12-week randomized, double-blind, placebo-controlled experiment designed to examine the effect of vitamin D supplementation (100 μg/d ) on insulin secretion, insulin sensitivity and glucose control in pre-diabetic black men and women aged 40 and older.
The objectives of this feasibility study are to evaluate the safety and functionality of the TANTALUS System with TANTALUS II IPG, to assess the effect of GCM signal application on trends of HbA1c, blood glucose and body weight changes.
In type 2 diabetic patients, abnormality in secretion or action of incretin(GLP-1, GIP) is observed. Although controversy still exists, the secretion of GLP-1 is thought to be reduced by 20-30% while GIP secretion is normal or slightly elevated, in type 2 diabetic patients. Various parameters such as the duration of diabetes, the amount of meal and their constitution, gastric bypass surgery, and some antidiabetic drugs affect the secretion of incretin. However, the secretion of GLP-1 and GIP in glucotoxic condition and whether they recover after improvement of glycemic status is not known. The investigators aim to study the effect of intensive insulin treatment in uncontrolled diabetic patients.
This study evaluates exenatide, sitagliptin, and glimepiride for the treatment of high blood sugar in patients with impaired fasting glucose or early type 2 diabetes. The purpose of this study is to determine if exenatide and sitagliptin increase the amount of insulin made by the pancreas compared to glimepiride. It is hypothesized that exenatide or sitagliptin will sustain or increase the amount of insulin made by the pancreas in comparison to glimepiride.
The purpose of this study is to assess safety and tolerablility of AZD1656 after multiple repeated oral doses in patients with type 2 diabetes on top of metformin.
The purpose of this study is to determine the effects of pioglitazone, once daily (QD), on heart functioning before, during and after stent implantation.
Saxagliptin is a new investigational medication being developed for treatment of type 2 diabetes. This Phase I study is designed to assess the pharmacokinetics of saxagliptin and its pharmacologically active metabolite, BMS-510849, following single and multiple oral doses of 5 mg saxagliptin in healthy Chinese subjects.
The purpose of this study is to assess safety and tolerability of AZD1656 after multiple repeated oral doses in patients with type 2 diabetes on top of insulin.
The aim of this trial was to compare postprandial metabolic response to glucose load in healthy overweight and type 2 diabetic subjects, by using glycemia, insulinemia, lipid profile, nutrient oxidation follow-up. Stable isotopes of glucose were used to assess postprandial total,exogenous and endogenous glucose kinetics.
This study will compare the efficacy and safety of exenatide versus placebo in adults whose diabetes is not fully controlled by insulin glargine with or without metformin and/or pioglitazone.
