Filter by:This study will enroll patients ages 18 and over who have a diagnosis of diabetes, are undergoing an elective surgery under general anesthesia and 1) are taking a GLP-1 receptor agonist medication, or 2) not taking a GLP-1 receptor agonist medication. The patients will have a gastric ultrasound prior to surgery to measure any retained gastric contents. The primary goal is to assess the effect of subcutaneous injectable GLP-1 agonists on preoperative gastric volume in fasted, diabetic surgical patients.
Glucagon-like peptide-1 (GLP-1), produced mainly in enteroendocrine cells, participates in energy homeostasis and glucose metabolism by regulating islet hormone secretion, gastrointestinal motility, and food intake, making GLP-1 agonist a treatment for diabetes and obesity. Pre-clinical and clinical studies have demonstrated that GLP-1 also has cardio-protection effects. GLP-1 agonists is able to improve markers of cardiac function, reduce myocardial infarct size and post-myocardial infarction remodeling in experimental myocardial infarction. And GLP-1 infusion improved left ventricular function and increases myocardial salvage in patients with acute myocardial infarction (AMI). The investigators' previous study found that GLP-1 analogues attenuated ischemia-reperfusion induced apoptosis of stem- and myocardial microvascular endothelial cells, and liraglutide (a GLP-1 analog) usage during hospital stay can prevent no-reflow and improve heart function in AMI. Therefore, the investigators carried out a cohort study to evaluate the association between plasma GLP-1 and in-hospital complications in patients with ST-segment elevation myocardial infarction.
Cigarette smoking is the leading preventable cause of premature death worldwide. However smoking is a very difficult addiction to break whereby main reasons for not quitting or relapsing after cessation are the nicotine withdrawal syndrome and post-cessational weight gain. GLP-1 analogues are well known to stimulate insulin secretion and to reduce energy intake and therefore body weight. Recent findings from animal and human studies suggest a role of GLP-1 in the pathophysiology of addiction. The putative role of GLP-1 analogues in nicotine reward regulation combined with its weight reducing effects might be of major interest in view of novel pharmacotherapeutic options for smoking cessation. - Substudy "fMRI": This substudy is to evaluate effects of Dulaglutide treatment on functional neuronal changes in smokers who want to quit smoking. - Substudy "Energy": This substudy is to investigate the effect of Dulaglutide (Trulicity®) on REE and further parameters associated with energy metabolism (bodycomposition, haemodynamic parameters and catecholamine action) in a subset of patients recruited for the main trial.
GLP-1(9-36) amide and (9-37), which was previously thought to be the inactive metabolite of GLP-1, also exerts cardioprotective effects. Direct administration of GLP-1(9-36) during reperfusion reduced ischaemic damage in isolated hearts and increased cGMP release, vasodilatation and coronary flow in AMI mouse model, one may speculate that total GLP-1 level may associate with adverse cardiovascular events in AMI patients, the hypothesis is therefore tested in this study.
Based on preclinical and small-sized studies in non-diabetic individuals, incretin-based therapies, i.e. glucagon-like peptide (GLP)-1 receptor agonists and dipeptidyl peptidase-4 inhibitors, may hold promise in preventing the onset and progression of diabetic kidney disease. However, the potential renoprotective effects of these agents, that are believed to be effectuated "beyond glucose control", have not been sufficiently detailed in human diabetes. Therefore, the present study aims to explore the mechanistic and clinical effects of GLP-1 receptor agonists on renal physiology and biomarkers in patients with type 2 diabetes. Forty patients with insulin-treated type 2 diabetes will undergo an eight week intervention with lixisenatide or insulin glulisine in order to assess changes in the outcome parameters.
Diabetes and high blood pressure are risk factors for developing heart disease. An increase in the number of diabetes patients is expected. This increases the number of patients with heart disease, and since the vast majority with diabetes die from heart disease, it is extremely important to investigate how these diseases can be prevented and treated. Studies in animals have shown that intestinal hormone glucagon-like peptide-1 (GLP-1) can expand blood vessels, thus lowering blood pressure, but it is not known whether the effects is found in humans, which we will investigate. Studies have also shown that GLP-1 lowers blood sugar, but it is unclear whether this is solely due to increased insulin production, weight loss associated with GLP-1 intake or GLP-1 has an effect on the muscles which increases the uptake of sugar. We investigate whether GLP-1 enhances the absorption of sugar in the leg. The investigators also examines whether these effects are greater in people with diabetes then in healthy.
The purpose of this study in humans is to define the effects of the endogenous hormone GLP-1 on gastroduodenal motility and on endocrine pancreatic secretion by using the specific GLP-1 receptor antagonist exendin(9-39). To elucidate possible cholinergic pathways, we combined exendin(9-39) with the muscarinergic antagonist atropine.
