Active clinical trials for "Diabetes Mellitus, Type 1"

This study is conducted in Asia. The aim of this observational study is to evaluate current status of diabetes management, control, and complications in diabetic subjects in Asia.

The purpose of this study is to develop and validate a survey instrument to be used by persons with type 1 diabetes aged 12 and older to screen for an eating disorder.

This study is an expansion of a previous study done to determine how thinking skills relate to hypoglycemia (low blood sugar) and certain regions of the brain in children and adolescents. In this study, the investigators are testing thinking skills and measuring brain activity in adolescents with and without type 1 diabetes mellitus.

This trial is conducted in Europe. The aim of this observational study is to evaluate the glycaemic control in patients with type 1 or 2 diabetes using NovoMix® 30 or Levemir® under normal clinical practice conditions.

Type 1 diabetes is a condition that is caused in part by an abnormality of the immune system which occurs when T cells, which are part of the immune system, damage the insulin secreting cells (islet cells) in the pancreas. Although it is known that T cells are important mediators of the disease, progress in the development of reliable T cell assays has been modest. The purpose of this study is to learn which T cell assays are most reliable and reproducible so that the investigators can improve their understanding about how type 1 diabetes occurs.

Over 50% of obese African-Americans (AA) presenting with newly diagnosed, severe hyperglycemia and/or unprovoked diabetic ketoacidosis (DKA) display clinical, metabolic, and immunogenetic features of type 2 diabetes. Prior studies indicate that these patients a) have markedly decreased insulin secretion and impaired insulin action at presentation, b) absent or low prevalence of beta-cell autoantibodies and c) are able to discontinue aggressive insulin therapy in ~70% of cases within 3 months of follow-up. These patients have been referred to as having ketosis-prone type 2 diabetes (KPDM). Most patients with KPDM, however, experience a hyperglycemic relapse within a year of insulin discontinuation. Consequently, patients with "KPDM" are an ideal model to follow throughout their clinical course. The specific aims of this proposal are to 1) identify clinical, metabolic, and immunogenetic markers that alone, or in combination, are predictive of short- and long-term near-normoglycemic remission and 2) determine whether pioglitazone or sitagliptin therapy will delay an insulin-deficient relapse once insulin is discontinued. The Principal Investigator hypothesizes that measures of beta-cell function at presentation, alone or in combination with measures of insulin sensitivity, will correlate with the ability of a patient to achieve and remain in near-normoglycemic remission. She also hypothesizes that intervention compared to placebo will preserve beta-cell function, improve insulin sensitivity, and prevent an insulin-deficient relapse. This prospective, cohort study with a RCT arm would better characterize the natural history of KPDM, facilitate the direction of long-term therapy, and likely decrease the recurrence of DKA which is associated with increased mortality and morbidity.

The purpose of this study is to determine whether magnetic resonance imaging (MRI) with ferumoxtran-10 can be used to detect changes in the pancreas associated with autoimmune diabetes.

Islets of Langerhans intended for clinical transplantation are labelled with a radioactive tracer. The tracer is retained in viable cells of the transplant. At infusion (transplantation) of the islets into the portal vein the tracer can be followed for two hours with positron emission tomography (PET). Imaging and calculations can give estimates of the proportion of surveying islets and the rate of early destruction. Also the distribution of the islets into the liver can be viewed.

Introduction : Cesarean rate varies from 45% to 73% in the literature in patient with diabetes type 1. Having a prior C-section is the most important risk factor. The aim of this study was to identify risk factor of cesarean in this population. Methods: This study is an observational, retrospective and single-center study from the hospital of Montpellier. All the pregnancies, planned or not, with subcutaneous insulin infusion or multiple daily injections of insulin, in patients with diabetes type 1 between 2009 and 2015, after 24 weeks of gestation were included. All the data were retrospectively collected by the principal investigator with computer and paper files.

The investigators hypothesise that patients with type 1 diabetes have clinically relevant, but often unrecognised, episodes of arrhythmias linked to episodes of hypoglycaemia and/or clinically significant fluctuations in plasma glucose.
