Active clinical trials for "Diabetes Mellitus, Type 1"

Determine the incidence of hypoglycemia during / after sexual intercourse among young adults with type 1 diabetes using continuous -type sugar meter IPRO for a week.

The first purpose of this study is to is to compare metabolic control of type 1 diabetes among children under the age of 7 years who use an insulin pump and a real-time (RT) glucose sensor, and children who use only insulin pump; the investigators will also determine dietary habits, their knowledge of type 1 diabetes management and emotional aspects of experiencing illness in the family, in both groups of children.

Type 1 diabetes results from the autoimmune destruction of the insulin-producing beta cells of the islets of Langerhans of the pancreas. Initially, diabetes is usually clinically silent with immune cells invading the pancreatic islets, a process termed insulitis, which eventually leads to loss of beta cells in the islets. If enough beta cells are destroyed, the body can not make enough insulin to maintain blood sugars in the normal range and clinical diabetes develops. The purpose of this study is to assess the ability of magnetic resonance imaging with ferumoxytol to detect changes in the pancreas associated with the insulitis of type 1 diabetes.

Diabetes Mellitus type 1 is characterized by an absolute insulin deficiency caused by T-cell-mediated autoimmune destruction of pancreatic β-cells . It is the predominant form of diabetes mellitus during childhood and adolescence. Hyperglycemia is a major cause of vascular and neuropathic complications that are seen in patients with diabetes mellitus type 1.

This study aims to describe the prevalence of additional autoimmune diseases and their specific antibodies at type 1 diabetes (T1D) diagnosis, and their incidence rate during follow-up, for children and adolescents. It also aims to describe the characteristics of the pediatric cohort followed since 2014 for type 1 diabetes by one of France's centers of reference for paediatric diabetes.

The main objective of this study is the objective evaluation of disease related sleep fragmentation in subjects with type 1 diabetes.

Personalized medicine methods in the management of type 1 diabetes

The purpose of this study is to assess the glycemic response to cycling road races (using continuous glucose monitoring ) in elite athletes with type 1 diabetes and non-diabetic controls. The investigators will also assess the relationship between power/work during cycling (using a power meter) and the subject's glucose profile.

Comparison of noninvasive glucose measurement performance versus standard invasive reference measurements.

It is well established that CD8 and CD4 T cells reactive against defined islet antigens are associated with initiation and progression of Type 1 Diabetes (T1D). In previous work, we have demonstrated that it is possible to redirect T cells against pathogenic T cells via chimeric peptide/MHC/CD3-zeta receptors in a peptide-specific manner and to prevent, or inhibit diabetes in NOD mice. In this study we intend to extend this approach to T cells of T1D patients. Working hypothesis: Beta cell-reactive CD8 T cells of human T1D patients can be immuno-targeted by their own gene-modified cytotoxic T lymphocytes (CTLs). Aims: Our major aim is to demonstrate, in a set of ex-vivo experiments, such immunotargeting with T cells derived from T1D patients at the Ziv Medical Center. To this end we will stimulate and expand autoreactive CD8 cells in blood samples of T1D patients and target them, ex-vivo, with genetically-reprogrammed CTLs which are present in the same blood samples.
