Active clinical trials for "Diabetes Mellitus"

The objective of the study is to evaluate the differences in the retinal microcirculation measured by OCT-Angiography in patients with type 1 diabetes between the diagnosis of the disease and after 3 months of insulin treatment.

The purpose of the trial is to discover and predict the development of GDM of pregnant women in their first trimester.

Osteopenia and osteoporosis, particularly related to insulinopenia, are common in type 1 diabetes and increase the risk of fractures. Musculoskeletal disorders of the upper limb are a common complication of type 1 diabetes. However, there is no official recommendation for screening for musculoskeletal disorders in France.

The aim of the prospective observational DISTEMI-Study in people with and without Diabetes mellitus (DI) after new onset of ST-Segment Elevation Myocardial Infarction (STEMI) aged 18-80 years at inclusion into the study is to characterize in detail the clinical, metabolical, immunological and vascular phenotype, investigate the interplay between myocardial remodelling and the metabolic phenotype, monitor the progression of the disease and compare the phenotype of STEMI people with diabetes mellitus to people with prediabetes and glucose tolerant people.

The overall aim of this project is to understand the independent roles of maternal factors, intrauterine exposures, genetic factors, and postnatal environment on the development of obesity and youth-onset type 2 diabetes (T2D) in childhood.

Continuous monitoring of glucose with a FreeStyle Libre pro sensor in diabetic and dialysis patients

Oral zinc supplementation in patients with diabetes mellitus can improve glycemic control. However, there is reluctance to recommend zinc supplements to these patients because there is no evidence that the zinc-dependent improvement in glycemic control offers protections from the cardiovascular morbidities associated with diabetes mellitus, especially myocardial infarction and thrombotic stroke. The investigators are conducting a randomized, double blind, cross over study to test the hypothesis that oral zinc supplementation will block the enhanced cardiovascular, cerebrovascular, and platelet reactivity that lead to myocardial infarction and stroke in research participants with diabetes mellitus.

The aim of this study is to describe the metabolic changes during pregnancy in women with type 2 diabetes or gestational diabetes in order to detect the pathophysiological mechanisms behind severe insulin resistance during pregnancy as well as the short- and long term consequences for mother and child. Included pathophysiological mechanisms potentially associated with severe insulin resistance are: Maternal hormonal, inflammatory and metabolic markers in the blood, as well as the level, content and bioactivity of exosomes and genetic variants associated with overweight and diabetes. In addition to the analysis on maternal blood, the same analysis will be performed on umbilical cord blood in order to determine the correlation between markers associated with insulin sensitivity in maternal and umbilical blood. Furthermore, fetal metabolic changes influence on fetal growth and development will be evaluated. Postpartum, the breast milk will also be examined for metabolic active substances that could influence the newborns growth and metabolism. Investigating one potential short-term consequence of diabetes during pregnancy, the association between insulin resistance and structural and functional changes in the placenta will be examined as well as the consequences of such changes on fetal growth and development. Investigating one potential long-term consequence of diabetes during pregnancy, the association between treatment with high doses of insulin during pregnancy and the future risk of developing cardiovascular diseases and heart failure will be examined.

Hypothesis: Type 2 diabetes mellitus is associated with pancreatic fibrosis that can be evaluated by minimally invasive imaging techniques. That fibrosis is associated with alteration of exocrine pancreatic function, defined as a reduced secretion of pancreatic enzymes and the development of nutritional deficiencies. To test that hypothesis, a prospective, observational, cross-sectional, comparative, case-control study has been designed. Pancreatic fibrosis will be evaluated by endoscopic ultrasound and quantitative elastography in cases (type-2 diabetes) and age-gender-matched controls without diabetes. Pancreatic function will be explored by fecal elastase test and nutritional evaluation. Calculated sample size is 94 patients (47 cases and 47 controls). Study period is 2 years.

This is a prospective observational study aimed at testing the existence of an association between frailty, inflammatory status, and degree of platelet activation and reactivity in elderly subjects with type 2 diabetes or coronary artery disease or Alzheimer's disease.
