The objective of this proposal is to provide quantitative dose-response data for effects of GLP-1 on myocardial glucose uptake in healthy control subjects and obese type 2 diabetic subjects, in support of the design of later studies evaluating therapeutic applications of GLP-1 to heart disease. Aim 1: To measure the effects of GLP-1 infusion on myocardial fuel selection in lean healthy humans under fasting (fatty acid-dominant) conditions. Four groups of 10 lean healthy subjects will be studied during infusions of 0 (saline control), 0.5, 1.5, and 4.0 pmol/kg/min GLP-1 (one study per subject). Cardiac metabolism will be measured using PET, using a dual-tracer approach which allows measurement of myocardial glucose uptake (the primary endpoint) along with total oxidation rate and myocardial perfusion (secondary endpoints). In concert with measures of circulating metabolites and regulatory hormones, the investigators will produce the most comprehensive assessment of actions of GLP-1 on myocardial metabolism in humans to date. Effects of each dose will be compared to the saline control, plus the investigators will combine all data and use nonlinear curve-fitting to derive sensitivity (ED50) and maximal responses for GLP-1 effects on myocardial glucose uptake. Aim 2: To measure the effects of GLP-1 infusion on myocardial fuel selection in obese type 2 diabetic humans under fasting (fatty acid-dominant) conditions Four groups of 10 obese type 2 diabetic subjects will be studied during infusions of 0, 0.5, 1.5, and 4.0 pmol/kg/min GLP-1 as under Aim 1. Analyses will be parallel to those described under Aim 1. Results from Aims 1 and 2 will be combined to allow direct comparison of the dose-response between nondiabetic control and type 2 diabetic subjects. No literature has been published to inform dose selection in the design of clinical trials of GLP-1 for modulation of heart fuel selection. With our expertise and experience in PET measurement of heart metabolism in diabetes, the investigators are uniquely positioned to fill this gap in knowledge. These studies are a necessary preamble to further evaluation of the potential for GLP-1 based treatments in heart disease.
The purpose of this study is to validate a predictive model of diabetic retinopathy progression in patients with diabetes mellitus type 2 patients to clinically significant macular edema (CSME) needing treatment either photocoagulation or intravitreal injections (ITV) using non-invasive techniques.
The purpose of this study is to demonstrate that combined vildagliptin-metformin therapy is associated with clinically significant reductions in biological markers of inflammation, pro-thrombogenicity, and atherosclerosis as compared to metformin mono-therapy in a population of diabetic patients with coronary artery disease who undergo cardiac rehabilitation. The pre-specified established biological markers of inflammation, pro-thrombogenicity, and atherosclerosis will include: interleukin-6 (IL-6 - primary biological marker), hs-CRP, platelet reactivity testing, MMP-9, Interleukin 1 beta (IL-1 beta) and adiponectin levels.
Double-blind, randomized, multicenter, multinational (South Korea and India), parallel group study The study was divided into three parts: part 1 was a screening period started with an initial 2 weeks of exercise/diet program; part 2 was a double-blind treatment period during which eligible patients were randomized to Sitagliptin 100 mg qd (once daily), LC15-0444 25 mg bid (twice daily), or LC15-0444 50 mg qd groups and received the assigned treatment for 24 weeks; part 3 was for those patients who completed part 1 & 2 and consented to receive another 28 weeks of treatment with LC15-0444 50 mg qd. Screening tests were performed on the patients who had given the written informed consent. After 2-week exercise/diet program according to the generally recognized guideline, eligible patients were assigned one of three treatment groups with 1:1:1 ratio. During the total of 24-week treatment period of part 2, each patient visited the study site at Week 6, 12, 18, and 24. Completing double-blind treatment for 24 weeks, each patient was asked to provide consent to participate in the part 3 of the study where all the patients were to receive LC15-0444 50 mg once daily. During 28-week treatment period of the part 3, each patient visited the study
Double-blind, randomized, multicenter, multinational (South Korea and India), parallel group study The study was divided into three parts: part 1 was started with an initial 2 weeks of exercise/diet program followed by another 2 weeks of single-blind placebo run-in period; part 2 was a double-blind treatment period during which eligible patients were randomized to LC15-0444 50mg or placebo groups and received the assigned treatment for 24 weeks; part 3 was for those patients who completed part 1 & 2 and consented to receive another 28 weeks of treatment with LC15-0444 50mg. Screening tests were performed on the patients who had given the written informed consent. After 2-week exercise/diet program according to the generally recognized guideline, patients took placebo for another 2 weeks while continuing exercise/diet program. When the 2-week placebo run-in period was completed, eligible patients were assigned either to placebo or 50 mg of LC15-0444 with 1:1 ratio. During the total of 24- week treatment period of part 2 after randomization, each patient visited the investigational site at Week 6, 12, 18, and 24. Completing treatment with placebo or LC15-0444 50mg for 24 weeks after randomization, each patient was asked to provide consent to participate in the part 3 of the study where all the patients were to receive LC15-0444 50mg regardless of the treatment received during the part 2 of the study. During 28-week treatment period of the part 3, each patient visited the investigational site at Week 30, 38, 46, and 52. Total study period from screening was 56 weeks per each patient.
Statins are commonly prescribed to lower cardiovascular risk in primary and secondary prevention. Despite their well known efficacy, statin withdrawal is a common event. Even a short term statin withdrawal can have dramatic consequences on atherosclerotic plaque stability, owing to a rebound in cholesterol levels and inflammation. The effects of a short term statin withdrawal on endothelial progenitor cells (EPC) and monocyte/macrophage polarization is unknown. In this study, the investigators will explore the effects of a 5-day statin withdrawal on EPC and monocyte/macrophage polarization, together with other inflammatory biomarkers in type 2 diabetic patients. The investigators hypothesize that statin withdrawal determines a reduction in EPC levels and an inflammatory cell polarization. Patients will be randomized to continue their habitual statin regimen or to withdraw statin. At baseline and 5 days later, blood samples will be collected for experimental measures.
Besides their potential action in the treatment of type 2 diabetes mellitus (T2DM), GLP-1 analogues decrease satiety and food intake leading to a significant weight loss in patients. However, little is known about their effects on food hedonic sensations and taste perception. The aim of this study is to investigate the impact of Liraglutide on the liking and wanting components of the food reward system, taste sensitivity and sensory specific satiety in type 2 diabetes mellitus (T2DM) patients. According to the review of literature in animal models, it is expected that Liraglutide will modify food preference and gustative perception in humans. Thirty T2DM patients will be studied before and after 3 months of treatment with Liraglutide (1.2 mg/day). Same tests will be carried out on two consecutive days before and after the treatment administration. Olfactory liking, recalled liking and wanting for several food items will be assessed. Sensory specific satiety will be measured as well as detection thresholds for salty, sweet and bitter tastes. Subjects will also answer questionnaires on hunger, pleasure in eating, and food intake.
Background: Little is known about the efficacy of intensive lifestyle therapy (i.e. increased physical activity and dietary changes) for the management of glycemia and cardiometabolic risk factors in children and adolescents with type 2 diabetes (T2DM). Our hypothesis is that education regarding healthy lifestyle changes will significantly reduce blood sugars in youth with T2DM that do not require insulin therapy. Our secondary hypothesis is that the intensive lifestyle therapy will cause quick and sustained reductions in health risk measured by body mass index (BMI), blood pressure, waist circumference, LDL cholesterol, serum triglycerides and apolipoprotein B.
