Filter by:Whereas physical activity clearly results in improvements in glycemic control in type 2 diabetes, in individuals with type 1 diabetes (T1DM) the impact of exercise on blood sugar control is more complex. In type 1 diabetes T1DM the inability to reduce exogenous insulin levels during exercise is a key factor that contributes to an increased risk of exercise-induced hypoglycemia. Since rapid adaptation of insulin dosage may be especially difficult in patients on a multiple daily injection regimen, alternative strategies are required to improve exercise-associated glucose stability. There is increasing evidence that the combination of steady state continuous low to moderate intensity exercise with short bursts of high intensity exertion (eg in the form of sprints) is an effective, well tolerated, novel strategy to prevent exercise-related hypoglycemia. A further promising option to stabilize blood sugar levels during and after exercise may be the ingestion of fructose in addition to glucose in form of a sport drink.
The purpose of this study is to assess the safety, pharmacokinetics, and pharmacodynamics of MK-1293 compared with a basal insulin (EU-Lantus™) in participants with Type 1 Diabetes. The primary hypotheses are that the duration of action, pharmacodynamic profile, and pharmacokinetic profile of MK-1293 and the comparator basal insulin are similar.
The purpose of this study is to compare the safety and efficacy of MK-1293 to Lantus™ in participants with T1DM. The primary hypothesis is that after 24 weeks, the mean change in hemoglobin A1c (A1C) from baseline is non-inferior in participants treated with MK-1293 compared with participants treated with Lantus™.
This project aims to evaluate the efficacy of autologous mesenchymal stem cell treatment to preserve insulin production and beta-cell mass in recently diagnosed patients with type 1 diabetes mellitus. The hypothesis to be tested is that an increased number of circulating mesenchymal stem cells will provide immune modulatory properties, and thereby stop the immune process in islets causing progressive beta-cell death.
This study will assess the safety and efficacy of secukinumab on the preservation of pancreatic beta cells in patients with newly-diagnosed type 1 diabetes mellitus.
Primary objective is to investigate the feasibility and stability of determining the endogenous glucose production during a hypoglycaemic clamp in type 1 diabetes mellitus subjects by a stable tracer to tracee ratio with an enrichment of 4% and a variation below +/-30%. Population: twenty type 1 diabetic subjects Study design: Single-center, open, non- randomized, pilot-study
Background: Type 2 diabetes mellitus is a main risk factor for cardiovascular disease and heart failure, in part due to diabetic cardiomyopathy. However, the association between intracellular lipid accumulation and (myocardial) functional impairment is likely more complex than originally imagined. Recent studies suggest that not fat per se, but the content of saturated or unsaturated fatty acids might predict the development of cardiac steatosis and myocardial dysfunction. In addition skeletal muscle and hepatic glycogen metabolism is impaired in patients with diabetes mellitus. Data from animal experiments suggest a relevant role of myocardial glycogen stores in ischemic preconditioning. Due to methodological limitations so far data on myocardial glycogen stores and myocardial lipid composition in humans are missing. Hypothesis: In addition to total ectopic lipid deposition in the myocardium, myocardial lipid composition, i.e. the relative abundance of saturated and unsaturated fatty acids, and impaired myocardial glycogen metabolism may play an important role in the development cardiac lipotoxicity leading to diabetic cardiomyopathy. Pancreatic endocrine function and myocardial morphology and function is altered in patients with heterozygote inactivating mutations of the CaSR-gene / FHH. Aims: - Metabolic virtual biopsy of the myocardium for identification of specific patterns of intracellular lipid composition and myocardial glycogen metabolism as possible critical determinants of metabolic cardiomyopathy - Characterization of the metabolic interplay between the myocardium, skeletal muscle, liver and adipose tissues in different stages of development of type 2 diabetes compared to patients with calcium sensing receptor mutation Methods: - 1H/13C and 31P magnetic resonance spectroscopy and imaging for measurements of myocardial, skeletal and liver lipid and glycogen content, abdominal adipose tissue distribution and composition, ATP synthesis and myocardial functional parameters - Mixed meal tolerance tests to trace the postprandial partitioning of substrates between insulin sensitive tissues (myocardium, skeletal muscle, liver, adipose tissue). - Hyperinsulinemic-hyperglycemic glucose clamp (HHC) with enrichment of the infused glucose with the stable isotope [1-13C]glucose to trace the incorporation of circulating glucose into myocardial glycogen in healthy insulin sensitive volunteers, prediabetic insulin resistant volunteers with impaired glucose tolerance, healthy subjects, patients suffering from type 2 diabetes mellitus, patients suffering from type 1 diabetes and patients with heterozygote mutation in calcium sensing receptor.
The endothelium is the lining of the blood vessels that helps prevent damage to the vessels. The endothelium does not function as well as it should in adolescents with type 1 diabetes. This causes future diabetes complications. Adolescents with diabetes also have abnormalities of the cells that repair the endothelium. These abnormalities may be due to damage caused by intermittent hyperglycemia. This studied is designed to study whether low dose, combined Vitamin C and E supplementation improves endothelial function and repair in adolescents with type 1 diabetes.
The purpose of this study is to use an Advisory/Automated Adaptive (AAA) Control system for insulin delivery in adults with Type 1 Diabetes (T1DM) in an outpatient setting to evaluate the system's ability to significantly improve blood glucose levels. This protocol represents a culmination of prior clinical trials in development of this AAA control system and benefits from the synthesis of those components.
