Filter by:The purpose of this study is to determine the safety and efficacy of AR9281, a novel s-EH enzyme inhibitor, in improving glucose metabolism and blood pressure in patients with impaired glucose tolerance and mild to moderate hypertension.
The main purpose of this study is to determine whether treatment with acarbose attenuates post-prandial glycemic excursions in non-diabetic/pre-diabetic obese children as determined by continuous glucose monitoring systems (CGMS). To this effect the current pilot study involves a 6 week intervention with acarbose given to all subjects with either impaired glucose tolerance or an area under the curve of >130 mg/dl during the screening oral glucose tolerance test. Three consecutive days of CGMS are then compared to before and during the intervention. The secondary objective addressed in this protocol is the collection of baseline measures of endothelial function in obese and lean children. Even though the duration of acarbose treatment may be too short to demonstrate a vascular effect, the pre and post intervention data would serve as preliminary data for anticipated future studies that assess the vascular effect of reduced post-prandial blood glucose levels.
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
Pioglitazone, a drug used in treatment of type 2 diabetes has been shown to improve insulin sensitivity in skeletal muscle, liver, and fat cells. Despite the beneficial effects of pioglitazone to improve insulin sensitivity and reduce cardiovascular disease in high risk type 2 diabetic patients, weight gain has been a limiting factor. Exenatide, another agent used for treatment of T2DM, improves glycemic control and promotes moderate weight loss. In this proposal we will examine the effect of combination therapy with pioglitazone plus exenatide on body weight, fat topography, beta cell function, glycemic control, and plasma lipid levels in subjects with type 2 diabetes mellitus compared to treatment with each drug separately. Assessment of beta cell function will be performed by measuring the maximal insulin secretory capacity using a maximal hyperglycemic stimulus combined with an intravenous arginine stimulus.
The purpose of this study is to examine changes in sugar metabolism that may occur in subjects who have previously had part of their pancreas removed due to a benign lesion.
The purpose of this study is to determine whether acarbose therapy can reduce cardiovascular-related morbidity and mortality in patients with impaired glucose tolerance (IGT) who have established coronary heart disease (CHD) or acute coronary syndrome (ACS). A secondary objective of the study is to determine if acarbose therapy can prevent or delay transition to type 2 diabetes mellitus (T2DM) in this patient population.
Subjects with impaired glucose tolerance will be randomized to either rosiglitazone or placebo for a 18 month period. The study will look at baseline, 12 month and 18 month data for exercise tolerance, coronary artery calcification and diabetes indicators.
The purpose of this study is to determine whether therapeutic intervention on impaired glucose tolerance in patients with coronary heart disease can decrease the incidence of new onset DM.
There is increasing evidence that inflammation plays a role in progression and destabilization of atherosclerotic plaque. FDG-PET can visualize activated metabolic activity of inflammatory cells. It is possible that FDG-PET can detect atherosclerotic plaque inflammation and that FDG-PET can monitor the effect of pioglitazone on plaque inflammation.
The prevalence of type 2 diabetes is increasing, which for most societies has considerable consequences not only regarding health but also economy. Type 2 diabetes develops through a "prediabetic" stage with impaired glucose tolerance. Intervention at this stage with change in lifestyle or with medication may prevent such progression. There are indications that vitamin D is of importance in glucose metabolism, and that supplementation with vitamin D may increase both insulin secretion and insulin sensitivity. Accordingly, supplementation with vitamin D may improve glucose tolerance and potentially prevent the development of type 2 diabetes in subjects at risk. However, this has so far not been demonstrated in a prospective, randomised clinical study. In the present study we will therefore include 600 subjects with impaired glucose tolerance (or impaired fasting glucose) detected in the Tromso study 2007/2008 and randomize to supplementation with vitamin D 20.000IU per week or placebo for 5 years. A glucose tolerance test will be performed each year, and development of type 2 diabetes will be the main endpoint.
