Filter by:Vitamin D supplementation in minority subjects with both pre-diabetes and low vitamin D levels will delay the development of diabetes.
The incretin hormone glucagon-like peptide-1 (GLP-1) has known insulinotrophic and glucagonostatic properties. However, inpatients with type 2 diabetes mellitus (T2DM)it is shown, that the beta cell sensitivity towards GLP-1 is decreased, when comparing to healthy controls. Further, these patients have decreased GLP-1 response to a meal. The aim of this study is to elucidate if the diabetic hyperglucagonemia, seen in these patients both during fasting and in a postprandial condition, is coursed by a decreased sensitivity to GLP-1 in the diabetic alpha cell. Ten T2DM patients and ten matched healthy control subjects will be examined on two separate days. Day 1: increasing GLP-1 infusions and Day 2: saline. During both days plasma glucose (PG) will be clamped at fasting level (FPG). Patients with T2DM will be submitted til a Day 3, here PG will be normalized over-night by an adjustable insulin infusion, on the following day the GLP-1 infusion of Day 1 will be repeated. The hypothesis is that these patients have decreased alpha cell sensitivity to GLP-1 as is the case with the beta cell sensitivity. This decreased sensitivity, the investigators speculate, contributes the defect suppression og glucagon and thereby to the increased PG levels seen in T2DM. Further the investigators will elucidate if this sensitivity can be increased by normalizing the diabetic PG to a normal FPG level.
An educational intervention in the General Medicine Clinic aimed at both primary care providers (PCPs) and their patients with metabolic syndrome/pre-diabetes (MetSyn/PDM). Improving PCPs ability to detect and manage MetSyn/PDM, as measured by the increased incorporation of MetSyn/PDM into PCPs care plan, and increasing patients' awareness of healthy lifestyle behaviors results in positive patient health behaviors and outcomes.
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.
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.
Hypothesis : The maximum body weight in lifetime is associated with the onset of development of type 2 diabetes.
The purpose of this study is to examine whether there is a causal relationship between insulin resistance and/or glucose intolerance in the development of a defect incretin effect.
The purpose of this study is to provide the necessary data and experience to design a larger, full scale clinical trial to determine if a certain medicine (repaglinide), which increases the amount of insulin secreted by the pancreas, can improve the nutritional status and pulmonary function of adolescents and young adults with cystic fibrosis and prediabetes by improving blood glucose control. The investigators are also trying to determine the relationship between systemic inflammatory factors and glucose impairment.
