Active clinical trials for "Diabetes Mellitus, Type 1"

The aim of the study is to research psychosocial and socioeconomic factors among families that might affect glycemic control in children and adolescent with type 1 diabetes mellitus. These factors might be: living conditions, structure of the family, socioeconomic status, divorces and parent's own glycemic control status (if parent's type 1 diabetes mellitus is present in the family).

Type 1 Diabetes Mellitus (T1DM) is a well-studied autoimmune disease resulting in insulin deficiency due to selective β-cell destruction. Epigenetics is a novel field of biology studying the inherited changes in deoxyribonucleic acid (DNA) expression which cannot be attributed to base sequence alteration. A relatively limited number of studies are published until now concerning T1DM in children and adolescents addressing epigenetics changes in DNA expression. The purpose of the present study is to analyze the methylation status of DNA within the promoter region of specific susceptibility genes such as Protein tyrosine phosphatase, non-receptor type 22 (PTPN-22), Insulin (INS) and Human leukocyte antigen G (HLA-G) genes.

The accuracy of the sensors (Dexcom G5 vs FreeStyle Libre Flash glucose monitoring) will be evaluated by simultaneous wearing of the 2 sensors during 2 weeks. During these 2 weeks the patients will do at least four capillary blood glucose measurements to compare with the sensor results. Patient satisfaction will be evaluated using a questionnaire that will be completed after the Dexcom G5 sensor has been worn for 1 month. The data recorded by the FreeStyle Libre Flash glucose monitoring system (average glucose,% above target, % within target, % under target, amount of hypoglycemia) in the month prior to the 2 weeks of double sensor wear will be compared to the same data recorded by the Dexcom G5 mobile CGM system during the first month of use.

Successful transition to an adult diabetes clinic is an essential part of both clinical and psychosocial care for emerging adults with type 1 diabetes (T1D). Pediatric patients are generally very well supported by their parents, significant others, and multidisciplinary clinical care teams, however, these support networks tend to change once patients reach adulthood and are required to transition to a more independent clinical care model with their adult care providers. This change can often be an overwhelming adjustment with a potential impact on patient's clinical and psychosocial outcomes. As part of the proposed mixed methods study, in Phase 1, the investigators will develop online questionnaires for primary stakeholders in the transition process to improve understanding of their needs, expectations, and experiences around transition. Based on findings from Phase 1, up to 30 individuals from each of the six groups will be interviewed to discuss their responses and better understand their needs around the transition process (Phase 2). Subsequently, findings from the qualitative analyses of the semi-structured interviews will inform the preparation of recommendations that may help facilitate a successful transition for the various stakeholder groups (Phase 3).

This case control study aims to determine whether spontaneous coronary artery dissection (SCAD) is associated with autoimmune diseases and to update the incidence of SCAD in a population-based cohort.

The incidence of type 1 diabetes is increasing worldwide and in France, including among young children. Type 1 diabetes has consequences for integration in community, especially on the management of hypoglycemia and hyperglycemia, mealtimes, participation in sporting activities and school trips. This works' purpose is to describe obstacles and difficulties to the integration in community before primary school (day care center, childminder, and nursery school) of a complete sample of children with type 1 diabetes followed in the Diabetology Department of Lyon Pediatric Hospital, at the start of the school year 2018-2019. The investigating team will carry out a descriptive study, using different questionnaires addressed to the professionals (nursery school directors, day care nursery directors, childminders, school doctors, pediatricians and doctors of child and maternal protection centers) and to the parents of children with type 1 diabetes. These different questionnaires will help to take into account different points of view, in order to identify all the obstacles to integration of children with type 1 diabetes in community. Through this work, secondary information actions through training and/or information leaflets will be carried out in order to facilitate the reception of these children in the community.

Despite the valuable information derived from older studies evaluating type 1 diabetes, the diabetes research community has, in large part, overlooked potential contributions of baseline abnormalities in β cell function to T1D development. Newer studies focusing on higher risk individuals often exclude family members without evidence of positive islet autoantibodies. New technologies to assay alternative biomarkers of β cell stress and death remain incompletely explored in both Ab negative and Ab positive family members of T1D patients. Specifically, modern biomarkers of β cell dysfunction have not been rigorously tested in combination with metabolic testing to fully understand their association with insulin secretion. The investigator's working hypothesis is that individuals at genetic risk for T1D exhibit baseline β cell dysfunction, even before development of detectable islet autoimmunity (seropositivity for islet Abs).

The present study is part of an overarching study being conducted in Denmark at Steno Diabetes Center Copenhagen (SDCC) and Nordsjællands Hospital Hillerød (NOH), Steno Tech, that aims to develop and ultimately, in a randomized controlled trial (RCT), test approaches that can assist people with type 1 diabetes in obtaining optimal outcomes using CSII. Through a large-scale, questionnaire-based online survey enriched with data from national registers, this sub-study contributes to this overarching aim by exploring the importance of individual differences across a wide range of factors, including demographic, socioeconomic, health status, psychosocial and preference structures, for optimal use of CSII in people with type 1 diabetes.

The benefits of Therapeutic Patient Education (TPE) have long been proven, but its implementation remains insufficient. It is only accessible to a part of the population and is too often limited to the acquisition of knowledge. TPE consists of supporting the patient in making decisions about his or her health, managing his or her life with the disease and treatment through the acquisition or maintenance of skills. Simulation is a pedagogical method of creating fictional or reconstructed environments in order to develop skills, know-how and abilities for which direct instruction is impossible for ethical, economic or technical reasons. To date, it is recommended for the development of caregiver skills, and has been the subject of two studies among family caregivers. It seems likely that simulation will add value to the methods currently used in TPE. To our knowledge, no studies have been conducted on simulation-based TPE (S-TPE) with patients. A consensus conference, which is a rigorous method of comparing the opinions of experts in TPE, simulation, patient experts and caregivers, was held in order to determine the learning that could be developed through simulation and the conditions of use. However, since the patient is a specific type of learner, we hypothesize that there may be some additional conditions for the use of S-TPE. And the value of this approach remains to be demonstrated. Since the use of S-TPE has never been studied with patients, a feasibility test would make it possible to evaluate, in the context of care, the possibility of its use and its acceptance by both patients and caregivers. This is necessary before considering a multicenter trial that demonstrates an interest in developing patient skills. It was decided to carry out this study in patients with diabetes, a condition for which TPE is a precursor. Caregivers will be able to objectify the advantages and limitations of using S-TPE.
