Active clinical trials for "Diabetes Mellitus, Type 2"

The investigators would like to conduct a randomized clinical trial to compare the efficacy of diabetes treatment between different gastric bypass procedures involving type 2 diabetics patients with BMI from 27.5 to 35 kg/m2

The aim of this study is to examine the effects of concentrated pomegranate juice on serum lipid profile and some inflammatory factors in patients with type 2 diabetes. Forty patients aged between 25-60 years old from both sexes are recruited. Patients consume 50gr/day concentrated pomegranate juice for 4 weeks. Anthropometric and blood pressure measurements, 3-days food-record questionnaire ,physical activity and fasting blood samples were collected at the beginning and at the end of the study. Fasting blood sugar, lipid profile, TNF- a, IL-6,hs -CRP and adiponectin levels are measured. LDL are calculated by formula. The participants are asked not to change their regular diet, medicine and activity during the study.

This is an open multicentre, randomized study to compare two treatment arms. One arm called "intensification of multiple injections" in which the patient will receive one supplementary injection of LEVEMIR®: that is to say 5 injections per day, and an arm called "continuous insulin infusion" via an external pump with APIDRA®. In the pump arm: a favorable effect in terms of improved insulin sensitivity, improved metabolic equilibrium, a decrease in the area under the baseline and prandial hyperglycemia curve noted during the continuous glycemia recording; an improvement in quality of life compared with treatment using multiple injections.

The use of dipeptidyl-peptidase 4 (DPP-4) inhibitors and glucagon like peptide 1 (GLP1) analogues for the treatment of diabetic mellitus (DM) type 2 is growing (1,2). Currently, some of these agents have been approved in combination with insulin. The potential for combined use with insulin has garnered increasing attention due to reduce side effects associated with insulin therapy and improve glycemic control. Some investigators reported that GLP-1 analogue combined with insulin reduces HbA1c and weight with low risk of hypoglycemia and high treatment satisfaction (3). However, their duration of treatment was short time with less than a mean of 3.0 years and the alterations of chronic diabetic complications by combination with incretin-based and insulin therapies are not known. We evaluated the long effects of adding incretin-based therapy (DPP-4 inhibitors or GLP-1 analogues) to insulin therapy on glycated hemoglobin (HbA1c) as glycemic control, body mass index (BMI), blood pressure (BP), insulin dosage, frequency of hypoglycemia, and chronic diabetic complications for 5 years-treatments.

Diabetes Mellitus (DM) can be regarded as one of the "epidemics" of the western world. DM contributes to severe morbidity and mortality due to damage in the target organs (neuropathy, vasculopathy, nephropathy, retinopathy). It affects the quality of life of the patients because of increased rate of blindness, IHD, stroke, end stage renal failure, hemodialysis and lower limb amputations (LLA).The Diabetic Foot (DF) is defined as destruction or infection of tissue/s in the foot of diabetic patients due to neurological damage and / or different levels of Peripheral Vascular Disease (PVD). Diabetic foot complications are the most common cause of lower extremity amputations in the industrialized world. The lifetime occurence of Diabetic Foot Ulcers (DFU) is 20% in diabetic patients. Between 15% - 25% of the foot ulcers will lead to lower limb amputations. It has been shown that Mesenchymal Stem Cells (MSCs) could be an effective therapy for many diseases including acute respiratory distress syndrome, spinal cord injury, liver injury and critical limb ischemia. Stem cells can be obtained from either the patient (autologous) or non-related healthy donors (allogeneic). The purpose of this study is to determine the safety and efficacy of cultured Bone Marrow Mesenchymal Stromal Cells (BM-MSCs) from allogeneic donors for treatment of chronic leg wounds of diabetic patients.

Type 2 diabetes mellitus (T2DM) results from early phase insulin secretory defect and insulin resistance. Studies have shown that most of the populations in which insulin resistance is considered to be the primary pathogenetic cause of diabetes, have a higher degree of obesity than those of primary insulin defect. Meanwhile, defective early insulin secretion plays a predominant role in the non-obese subtype of T2DM which includes majority of Japanese patients. Sitagliptin is a dipeptidyl peptidase-4 (DPP-IV) inhibitor as indicated for the treatment of T2DM. Sitagliptin increases plasma concentrations of active glucagon-like peptide-1 (GLP-1) and active glucose-dependent insulinotropic peptide (GIP) two- to three-fold in patients with T2DM. The effect of sitagliptin on GLP-1 results in lower fasting and postprandial glucose concentrations through increases in glucose dependent insulin release and suppression of inappropriate glucagon secretion. Namely, several mechanistic studies using standardized meal showed that sitagliptin improved glucose control with decreased glucagon levels and increased insulin concentration in obese or overweight T2DM patients with BMI > 25 kg/m2. However, how sitagliptin affects islet function, including glucagon secretion in non-obese patients with low insulin secretion are not known. Therefore, the investigators will examine the effect of sitagliptin on glycemic control and the mechanism involved using a standardized test meal in non-obese Japanese patients with T2DM whose BMI levels are < 25 kg/m2.

Exercise is considered a way to benefit the health of unhealthy and healthy individuals. This is confirmed by different scientific researches, in which people who participated improve their health. The present study will be conducted to test the hypothesis that vildagliptin associated with metformin may have more impact in improving glucose variability after a sub-maximal exercise test, as compared to glibenclamide. Our general aim will be to evaluate glucose variability after the submaximal exercise test under the treatment with vildagliptin or glibenclamide. The specific aims of this study are to evaluate the oxidative stress, endothelial function, metabolic and cardiovascular responses to exercise under the treatment with vildagliptin or glibenclamide. All these responses are important in patients with Diabetes Mellitus type II. Allied to the patient's routine treatment (metformin), they will receive orally a second drug, to take in 12 weeks. The patients will be raffled to take one of the two drugs that act on glycemia, that are called vildagliptin (50 mg of this drug twice a day) and glibenclamide (5 mg once a day during the first week and later you will increase to 5 mg twice a day). The metformin drug will continue be used. Patients who meet the eligible criteria for the study will first make the test of the maximum effort, to determination of peak oxygen consumption (VO2peak) and ventilatory thresholds. Forty eight hours after this test, patients will be allowed to do the pre-drugs protocol that will be given in three consecutive days as explained below. Day 1: Begin a 24-hour urinary collection, perform vascular doppler ultrasound to evaluate endothelial function and then the glucose sensor will be inserted subcutaneously (begin continuous glucose monitoring system - CGMS evaluation); Day 2: End the 24-hour urinary collection, submit to the submaximal test (blood collection at baseline, 15 and 30 min of the session, and 60 min after recovery). On the same day, the patients will begin 24h ambulatory blood pressure monitoring (24h-ABPM). Day 3: Removal of the glucose sensor; end of the 24h ABPM, randomization. This same protocol, except the randomization will be repeated at the end of the 12 week treatment.

The purpose of this study is to determine the effects of non surgical periodontal treatment on glycemic control in type II diabetics.

QUDOS is a cross-sectional population study aiming to answer key questions about diabetes and its complications in Qatar as well as identify factors associated with the development and progression of diabetes complications.
