Filter by:High blood glucose levels in hospitalized patients with diabetes are associated with increased risk of medical complications and death. Improved glucose control with insulin injections may improve clinical outcome and prevent some of the hospital complications. Glargine (Lantus®) insulin injection is the most common treatment of diabetes in the hospital. Sitagliptin (Januvia®)is effective in lowering blood glucose. In a recent pilot study aiming to determine differences in glycemic control between treatment with sitagliptin (Januvia®) alone or in combination with basal insulin and basal bolus regimen in general medicine and surgery patients with type 2 diabetes (T2D). The investigators found that treatment with sitagliptin alone or in combination with basal insulin resulted in similar glycemic control compared to basal bolus regimen. The investigators will conduct a prospective RCT aimed to determine the safety and efficacy of sitagliptin therapy for in-hospital and post-discharge management of general medicine and surgical patients with T2D. A total of 280 patients with known history of diabetes will be randomized to receive sitagliptin plus basal (glargine) insulin once daily (group 1), or basal bolus regimen with glargine once daily and aspart or lispro insulin before meals (group 2). If needed, patients in the treatment groups will receive correction doses of rapid-acting insulin in the presence of hyperglycemia (BG > 140 mg/dl). The overall hypothesis is that treatment with sitagliptin in combination with basal insulin in patients with type 2 diabetes will result in a similar improvement in hospital and post-discharge glycemic control and in a lower frequency of hypoglycemic events than treatment with basal bolus insulin regimen with glargine once daily and lispro insulin before meals. Patients will be recruited at Grady Memorial Hospital, Emory University Hospital, University of Michigan, Ohio State University and Temple University
The study investigates the safety, tolerability and efficacy of a single intravenous infusion of two doses of mesenchymal precursor cells versus placebo in subjects with diabetic nephropathy and type 2 diabetes.
This is a non-inferiority study comparing omarigliptin with sitagliptin in participants with type 2 diabetes mellitus (T2DM) with inadequate glycemic control on metformin therapy. The primary hypothesis is that after 24 weeks, the mean change from baseline in hemoglobin A1c (A1C) in participants treated with omarigliptin is non-inferior to that in participants treated with sitagliptin. There will be a 2-week run-in period with placebo + metformin prior to the double-blind treatment period.
The main objective of the study is to estimate and compare the percentage of patients with abnormal glucose metabolism at 4-12 weeks postpartum between two groups: patients diagnosed with gestational diabetes before or after 24 weeks of pregnancy. Abnormal glucose metabolism is defined as type 2 diabetes, glucose intolerance or impaired fasting glucose.
Recent data suggest that the trillions of bacteria in gastrointestinal tracts (gut microbiota) can function as an environmental factor that modulates the amount of body fat. Obese individuals have an altered gut microbiota and germ-free mice are resistant to developing diet-induced obesity and have lower fasting insulin and glucose concentrations and shows an improved glucose tolerance. Administration of the probiotic bacterium Lactobacillus Gasseri SBT2055 in fermented milk for 12 weeks reduced adiposity and body weight in obese adults possibly by reducing lipid absorption and inflammatory status. However, there are no controlled studies to the investigators knowledge that address whether probiotic supplementation affects glucose metabolism. The investigators hypothesis is that supplementation of Lactobacillus reuteri DSM 17938 may improve metabolic control in type 2 diabetes patients. In addition, the investigators will explore possible mechanisms behind the antihyperglycemic action of Lactobacillus Reuteri.
Diabetes mellitus is a metabolic disease with a growing prevalence worldwide, affecting 171 million people in 2000 and an expected 366 million people in 2030 (1) and therefore diabetic nephropathy is rapidly increasing in the Western hemisphere and represents in up to 50 % the cause of end stage renal disease. Hence, early intervention is desirable to prevent any damage to the kidneys. In the early stage of diabetic nephropathy, endothelium dysfunction is a key pathogenetic process as indicated by increased leakage of albumin through the glomerular barrier (2). Hence, improvement of endothelium function is an attractive therapeutic goal of antidiabetic medication. Endothelial dysfunction, in particular basal nitric oxide activity, has been also identified as pivotal determinant of glomerular filtration rate (3). A new and promising class of antidiabetic drugs are the gliptins. Gliptins act by inhibiting the enzyme dipeptidyl peptidase-4 (DPP-4), which is responsible for the rapid inactivation of glucagon-like peptide-1 (GLP-1) - an incretin hormone of the gut (6 - 8), thereby enhancing and prolonging the effects of GLP-1. GLP-1 - member of the incretin hormones - is released into the blood after meal ingestion and stimulates the insulin secretion in a glucose dependent manner. This accounts for the marked prandial insulin response, which prevents prandial hyperglycemia. Apart from surrogate parameters like reduction of fasting and postprandial blood glucose levels or improvement of HbA1c, the effect of gliptins on micro- and macrovascular function and cardiovascular outcome has not been the primary focus of current studies. However, infusion of GLP-1, the incretin hormone affected by gliptins has been reported to ameliorate endothelial dysfunction in patients suffering from coronary artery disease (9) and it was recently shown that infusion of GLP-1 into healthy human subjects increases both normal and ACh-induced vasodilatation (10). In studies on rats with diabetes, GLP-1 infusion nearly re-established their normal vascular tone (11) and there are further data from experimental animals that indicate a beneficial effect of GLP-1 on endothelial function (12). It is of major interest whether therapy with gliptins improves endothelial function of the micro- and macrovasculature. In face of the burden that diabetic nephropathy causes, the effect of linagliptin on the renal vasculature and endothelium integrity of the renal circulation (as measured by the availability of nitric oxide), is a key stone in order to claim that linagliptin is an effective antidiabetic agents. There is a need to demonstrate that linagliptin is effective beyond its blood glucose lowering actions and improves vascular endothelium function in the kidney.
We randomize individuals with impaired glucose tolerance to one of three arms for degree of physical activity: 1. Continue with your current life style; 2. Ordinary life activities for increased physical activity; 3. Scheduled group activities for changed behavior. The overall aim is to focus on change of physical activity and to keep other life style activities more or less unchanged (diet, smoking, etc) and the effect on metabolic variables.
This is a pilot study to show that it is possible to identify the specific types of fats in blood, adipose tissue, and liver tissue. The study doctors hope to use the analysis of these fats to learn more about nonalcoholic fatty liver disease (NFLD). Nonalcoholic fatty liver disease is the accumulation of fat in the liver of people who have minimal alcohol exposure. Nonalcoholic Fatty Liver Disease is associated with obesity and insulin resistance, and predicts development of Type 2 Diabetes. The study doctors are interested in looking at the relationship between liver fat and insulin resistance.
The prevalence of diabetes in pregnancy is rising in all maternal age groups. There is increasing evidence that in-utero exposure to maternal diabetes is associated with an increased risk of obesity and type 2 diabetes in children and adults. There is an urgent need to reduce these increasing rates of obesity and diabetes in subsequent generations. The MiTy Trial (Metformin in Women with Type 2 Diabetes in Pregnancy Trial) is a CIHR-funded multi-centre, randomized controlled trial of women with type 2 diabetes in pregnancy (sample size n=500). The MiTy Trial is looking to determine the effect of the addition of metformin to a standard regimen of insulin in women with diabetes, on perinatal morbidity and mortality. The MiTy Kids Trial is a follow-up to the MiTy Trial which will determine whether treatment with metformin during pregnancy in women with type 2 diabetes will lead to a reduction in adiposity and improvement in insulin resistance in the offspring of women with diabetes at 2 years of age.
The purpose of this protocol is to measure and compare levels of the circulating protein adiponectin and adiponectin's association with insulin sensitivity in Mexican Americans and non-Latino white subjects. The investigators also aimed to examine associations between nutritional factors and adiponectin levels.
