The 6 month study includes 300 participants that are randomized to an immediate treatment group or a delayed intervention group. The primary outcomes include changes in HbA1c and patient reported outcomes and experience measures. Qualitative interviews with various stakeholders will explore issues relating to successful implementation.
Type 2 diabetes is the predominant type of diabetes. Because a quiet evolution, it is difficult to have a rapid diagnose. A better knowledge about pathophysiological mechanisms at the origin of type 2 diabetes and about its complications could make it possible to improve the prevention and the treatment of this disease. Research team developped a new research axis : the microbiota of the intestinal mucosa. They proved a translocation process of intestinal bacteria from the intestinal mucosa to different tissue of the organism implicated in glucose homeostasis. This mechanism is involved in the type 2 diabetes development. A clinical study (MICIMAB) of predictive biomarkers of diabetes and obesity is ongoing. In parallel, the same team explored the role of intestinal immunity modifications in the bacteria translocation from the gut to the blood circulation. They already have some results on animal model but not yet in human. In animal model, a solid reduction of lymphocytes T CD4 Th17 in the intestinal wall is responsable of the translocation of intestinal bacteria and in the induction of a metabolic inflammation wich promotes insulin resistance, abdominal obesity development and type 2 diabetes. The aim of this study is to explore this hypothesis in human to have therapeutic solution later.
Lean tissue intracellular triglycerides (ICTG) accretion is an important marker of lean tissue lipotoxicity that significantly contributes to the development of type 2 diabetes (T2D). The mechanisms leading to excess exposure of lean tissues to fatty acids involve metabolic dysfunctions of adipose tissues and lean tissues themselves. Understanding the role of white and brown adipose tissue in this metabolic dysfunction is particularly important in predicting, preventing and treating T2D and many of its associated cardiovascular complications. A recent breakthrough has been the demonstration that the acute oral administration of a β3 adrenergic agonist, mirabegron (200 mg), significantly increases BAT glucose uptake in healthy individuals. This suggests that mirabegron could be used as a pharmacological tool to selectively activate BAT metabolism as part of the mechanistic studies on BAT. It also suggests that mirabegron could be used pharmacologically for chronic activation of BAT in clinical trials to treat obesity and T2D. However, there are some outstanding issues regarding the use of mirabegron to activate BAT. First, there has been no direct comparison of the effect of acute cold vs. mirabegron on BAT metabolism. Second, there has been no demonstration of the effect of mirabegron on BAT oxidative metabolism since glucose uptake is only a surrogate of BAT energy expenditure. Third, acute administration of mirabegron led to significant increases in blood pressure and cardiac work, suggesting that it may also enhance energy expenditure in other organs in addition to BAT, thus confounding the role of BAT in energy homeostasis. Therefore, much remains to be known about the effect of mirabegron on BAT and cardiac energy metabolism before this drug can be used as a selective activator of BAT oxidative metabolism. The purpose of this study is to directly compare BAT oxidative metabolism under cold vs. β3-adrenergic agonist stimulation in lean healthy individuals. The investigator hypothesizes that the acute oral administration of a lower dose of mirabegron (50 mg) will result in an increase in BAT oxidative metabolism and whole-body energy expenditure, to a similar extent as cold exposure, without influencing the cardiovascular responses previously seen with the higher dose (200 mg).
This is a randomized controlled study in type 2 diabetic patients who are presently uncontrolled on at least 2 injections of insulin daily with an A1C >7.5 % and <10%. Patients need to be stabilized on their MDI for 1 week then randomized to either SBGM or FreeStyle Libre for 10 weeks.
The purpose of this study is to use a randomized, double-blind, placebo controlled study design to comprehensively investigate the impact of 8-weeks of dietary nitrate supplementation on skeletal muscle blood flow, mitochondrial function, and exercise capacity in patients with type 2 diabetes (T2D).
The continuously increasing prevalence of cardiovascular diseases, type-2 diabetes, and COPD is a major health problem in developed countries and is mainly caused by an unhealthy lifestyle. Most important lifestyle related causes of morbidity and mortality are smoking, obesity and physical inactivity, and increasing rates of obesity and physical inactivity in combination with smoking will lead to an increase in the number of patients with lifestyle related diseases in the coming decades. There is, therefore, an urgent need to identify and establish strategies and to implement interventions, allowing for the identification and management of citizens at increased risk of disease. Two recent systematic reviews of general practice based health checks suggest that people at increased risk of a chronic disease may benefit from a targeted approach to health checks. Targeted or selective preventive actions are a generally accepted and well integrated part of the health care system (e.g. treatment of hypertension and hyperlipidemia). However, selective prevention is challenged in terms of how to identify citizens at increased risk of disease in the general population in order to start the indicated preventive actions. The aim of the present pilot study is to test the acceptability, feasibility and short-term effect of a selective preventive program that systematically helps citizens evaluate individual risk of lifestyle related disease and offers targeted and coordinated preventive services in the primary health care sector. The intervention comprises four elements: 1) Systematic collection of information on lifestyle risk factors using questionnaire 2) Risk estimation and stratification into risk groups based on questionnaire data and information from the electronic patient record (EPR) using validated risk estimation models, 3) An individual electronic health profile with personalized advise on lifestyle change and 4) targeted preventive services at the general practitioner (GP) or the municipality for citizens at risk of lifestyle disease and citizens with risk behavior, respectively. The intervention is supported by a patient-centered health information system that facilitates informed patient action and integrates general practice and municipality health care providers.
Patients with type 2 diabetes have many complications in different organs. These complications are extremely frequent and severe: cardiovascular and renal disease, visual impairment, and, more recently, complications affecting bone such as fractures. Conventional methods for the evaluation of fracture risk are based on the Bone Mineral Density (BMD) or FRAX (algorithm for the prediction of osteoporotic fracture risk) are not sufficient in the context of diabetes. Several metaanalyses have shown that, paradoxically, a higher BMD in patients with type 2 diabetes compared to patients not suffering from this disease, independently of body mass index (BMI). The paradoxal increase in fracture risk, despite a high BMD has led to the hypothesis that diabetes induces a modification of the quality and not the quantity of bone. However, there is a lack of data as to bone quality in patients with type 2 diabetes as studies of bone biopsies from patients with type 2 diabetes are extremely rare. The objective of the study is to compare bone quality in patients with type 2 diabetes to that in patients who do not suffer from type 2 diabetes: evaluation of vertebral fractures by osteodensitometry, measurement of Trabecular Bone Score (TBS), and analysis of bone quality in biopsies (advanced glycation end products (AGE), contents of bone matrix and analysis of mineralization). The results will then be correlated with blood/urinary markers with the objective to determine one/several non-invasive biomarkers for bone status in diabetic patients.
To assess the effect of sodium-glucose cotransporter 2 (SGLT-2) inhibitors on blood pressure and urinary angiotensinogen. This is a cross over study design, where 40 subjects will receive Dapagliflozin for 6 weeks followed by placebo for 6 weeks, or placebo for 6 weeks followed by Dapagliflozin for 6 weeks. In addition there will be an arm of 10 subjects who will receive sulfonylurea in an open label as a comparative to the cross over subjects to assess if the effect of Dapagliflozin may also be in part due to improved glycemic control.
In normal physiology, glucagon from pancreatic alpha cells plays an important role in maintaining glucose homeostasis via its regulatory effect on hepatic glucose production. Patients with type 2 diabetes exhibit elevated plasma glucagon levels in the fasting state, and in response to ingestion of glucose or a mixed meal.glucagon, glucagon concentrations fail to decrease appropriately and may even increase. This diabetic hyperglucagonaemia may therefore contribute importantly to the hyperglycaemia of the patients. Several glucose-lowering treatment modalities have been shown to affect glucagon levels in patients with type 2 diabetes, but the role of glucagon in the glucose-lowering effects of these treatment modalities has been difficult to discern. By using a glucagon receptor antagonist (GRA) the investigators will exploit glucagon receptor antagonism to delineate the role of glucagon during treatment with sodium-glucose co-transporter 2 (SGLT2) inhibitors and dipeptidyl peptidase 4 (DPP-4) inhibitors, which have been shown to increase and decrease plasma glucagon levels, respectively.
