Filter by:This study is being done to determine if pioglitazone (Actos) is helpful to patients with type 2 diabetes and could possibly prevent harmful consequences of cardiovascular disease in diabetic patients.
Trial of new insulin injection pen called Pre-filled Pen B by type 2 diabetics in take home situations. Patients must use insulin lispro injection [rDNA origin] Low Mix twice daily during the trial.
Incretin hormones (GIP and GLP-1) stimulate insulin release in a glucose dependant manner, hence are necessary for maintenance of normal glucose tolerance. Both GIP and GLP-1 are degraded and inactivated by DPP-4. LAF 237 is an inhibitor of DPP-4 that has been shown to increase meal-stimulated levels of intact GLP-1 in animals and patients with T2DM.. The purpose of the current study is to explore the acute effects of LAF237 on the rate of appearance and disappearance of glucose in type 2 diabetics. Secondary objectives include the effect on FPG, insulin secretion rates, glucagon and FFA levels, and rate of glucose entry from the GI tract.
This is an open label, observational study designed to collect data that characterize the use of SYMLIN following the introduction of the medication into the marketplace. Health care providers and subjects selected for study participation are intended to be representative of those providers prescribing, and subjects receiving, SYMLIN therapy.
In this study, the effect of miglitol on daily plasma glucose will be evaluated in type 2 diabetic patients treated with insulin.
The purpose of this study is evaluate the clinical efficacy and safety of Miglitol in patients with Type2 Diabetes Mellitus with treated insulin.
The purpose of this study is to examine the effects of treating insulin resistance on memory and attention, brain glucose utilization, and proteins in spinal fluid.
Obesity is a multinational epidemic. There is evidence that despite educational measures and increased public awareness, the number of obese individuals continues to increase. Of the numerous obesity-related comorbidities, type 2 diabetes remains one of the most significant in terms of mortality and health care costs. Gastric Bypass Surgery (GBS) not only offers an effective form of therapy for morbid obesity, but also amelioration of type 2 diabetes mellitus. The normalization of glucose levels in GBS patients occurs within days after surgery and has been shown in surgical literature to be independent of the weight loss after surgery. The proximal gut, the site of release of certain incretins, may play a role in glucose homeostasis in obese individuals with type 2 diabetes mellitus. One such incretin is GIP, which when released into the circulation during the immediate postprandial period, accentuates the insulin response to a glucose meal. It is hypothesized that overactivity of this enteroinsular axis in obese individuals produces cell resistance to insulin and subsequent type 2 diabetes mellitus. A previous study reported elevated fasting GIP levels, as well as an exaggerated GIP response to a glucose meal, in obese subjects, which was significantly reduced months after GBS following weight loss. This pilot study of obese patients scheduled for GBS will compare the serum levels of certain peptides, including GIP, following a glucose meal before and after GBS, before weight loss has occured. In order to reproduce the preoperative state, and therefore to demonstrate the physiologic change, a small group of subjects who undergo open surgery will undergo the same measurements after surgery, but using a model in which the meal traverses the stomach, duodenum and jejunum with the aid of a gastrostomy tube.
Phase I, 6 weeks: Intensive weight loss 42 obese subjects with type 2 diabetes mellitus or impaired fasting glucose (FBS greater than 100 mg/dl) and a patient at the Nutrition and Weight Management Center at Boston Medical Center will be randomized to receive either an MCT-based or LCT-based liquid diet for a 6 week period (Phase I) to establish compliance followed by a second 6 week period (Phase II). These diets will be isocaloric (1083 kcal/day) and identical except for the quality of the fat. The intervention will be double blinded. The MCT diet will consist of 5 liquid meals using a commercial product plus 34 grams MCT oil (Life Enhancement Products, Inc. Petaluna, CA; 8.3 kcal/gm) added per day to the HMR shakes. The LCT diet will utilize 5 HMR shakes plus 31.5 grams LCT oil (corn oil; 9 kcal/gm) per day. Patients in both groups will be given a list of supplemental foods that are suitable for the study. They may choose to eat up to an additional 400 kcal per day from this list and will be asked to add these to their food records for monitoring of their caloric intake. A dietitian will instruct subjects at a baseline visit on behavior modification and a moderate physical activity program. Baseline testing includes the following: Body composition by DEXA (Hologic); Subcutaneous abdominal adipose tissue biopsy; blood work. Subjects who do not lose 5% of their baseline weight by the end of Phase I will be withdrawn from the study. If subjects do not lose 5% in Phase I, they will be considered inappropriate for a liquid diet, and therefore for the study, and will be discontinued from the study. Phase II, 6 weeks: Continued weight loss program during phase II, subjects will be maintained on the same diet, supplements and exercise program. Once patients enter Phase II, all baseline lab measurements will be repeated. Needle biopsies of subcutaneous abdominal adipose tissue will be obtained at the beginning and at at the end of Phase II. Finger-stick blood glucose levels will be checked weekly. At the end of Phase II, and of the study, fasting blood work will be obtained. At the end of Phase II, the following procedures will be performed: Subcutaneous abdominal adipose tissue biopsy (total = 3). Body composition by DEXA (Hologic) (total = 2).
Abnormalities in peripheral glucose regulation and type 2 diabetes can occur more commonly in individuals with schizophrenia than in healthy subjects or in other psychiatric conditions. Antipsychotic treatment may contribute significantly to abnormalities in glucose regulation. Hyperglycemia can contribute to long-term cardiovascular disease risk that may already be increased in patients with schizophrenia due to higher rates of smoking, sedentary life style, obesity and under-treated hypertension and dyslipidemia. This project will characterize the effects on glucose control of the two most commonly prescribed newer antipsychotic medications, risperidone and olanzapine, in patients with schizophrenia. This proposal specifically hypothesizes that olanzapine treatment will be associated with decreases in insulin sensitivity (SI), without effects on insulin secretion. Treatment-related effects on glucose effectiveness (SG) will be explored.
