Filter by:An experimental mechanistic study. The overall objective is to gain new knowledge about mechanisms involved in adaptation to recurrent hypoglycaemia in diabetes by investigating patients with type 1 diabetes and healthy controls. The knowledge to be obtained may feed into experimental hypoglycaemic clamp studies to further elucidate the effect of the adaptations during acute hypoglycaemia. Ultimately, it may lead to intervention studies aiming at the maintenance of functional capability during hypoglycaemia in patients with type 1 diabetes to reduce their risk of severe hypoglycaemia.
This is an observational study, in which newborn infants from the general population are screened at birth for HLA-conferred susceptibility to type 1 diabetes and celiac disease. The participants carrying genetic susceptibility to type 1 diabetes (approximately 9.5%) will be analyzed for diabetes-associated autoantibodies at the age of 1, 2 and 3 years, while those predisposed to celiac disease (about 14%) will be screened for tissue transglutaminase antibodies at the age of 1 and 3 years. The intention is to screen annually 10,400 newborn infants for a period of 3 years. About 988 infants are each year identified as a child at risk for type 1 diabetes, and it is expected that around 80% of the families with such a child are willing to join the autoantibody screening. Approximately 1456 infants are each year recognized as a child at risk for celiac disease, and again the expectation is that 80% of the families will join the antibody screening program.
Open single armed study to investigate safety and feasibility of administrating autologous T regulatory cells at the time of allogenic islet transplantation.
This study will be conducted on human subjects and is observational, prospective and uncontrolled, defined as a category 3 according to the Jardé Law (RIPH3). It is a national and multicentric study. Enrolled patients are Type 1 Diabetes (T1D) patients who receive the DBLG1 System (CE marked medical device) to be treated. Patients have their regular visits with their own clinician. No change from their usual care must and will be done, including trainings and treatment. At the end of the study, patients will keep their system for their usual care and will continue having usual follow-up visits with their clinician. Data related to their glycemia, complications and quality of life will be collected for 1 year from the beginning of their treatment. A comparison with data collected during the 2 weeks of run-in period, prior to the activation of loop mode, is planned. In case the run-in phase lasts longer than 2 weeks, data collected from the two last weeks only will be kept for analysis and comparison. The study is completed when all patients have their "end of study" file completed in the electronic Case Report Form (eCRF).
The investigators aim to further the understanding of environmental factors that underlie the development of Type 1 diabetes (T1D) and the post-onset disease trajectory. Dysbiosis, defined as alterations in intestinal microbiota composition and function, has been hypothesized to increase the risk of developing T1D in those with genetic susceptibility. Dysbiosis may result from modern dietary habits, such as broad consumption of the highly processed Western Diet, or by widespread use of antibiotics. Here, the investigators propose to examine the impact of dysbiosis on the endogenous innate inflammatory state that potentiates T1D progression. The investigators hypothesize that probiotic-induced alterations in the intestinal microbiota may favorably alter the post-onset disease state.
The goal of DIATAG study is the identification of biomarkers of T1D evolution in a pediatric cohort.
An open label, parallel single centre trial of Wharton's Jelly derived allogenic mesenchymal stromal cells repeated treatment to preserve endogenous insulin production in adult patients diagnosed with type 1 diabetes
The scientific basis for dietary recommendations in type 1 diabetes is almost lacking, with the current recommendations being based on type 2 diabetes studies. Therefore the overall purpose of this study is to improve the current evidence for dietary recommendations to people with type 1 diabetes. Study aim: To compare how a strictly low carbohydrate diet, a moderately low carbohydrate diet and a traditional diabetes diet (with higher amounts of carbohydrates) affect insulin requirements and metabolic control in individuals with type 1 diabetes. Carbohydrate intake is 50-60% of the total energy intake in the traditional diabetes diet, 30-40% in the moderately low carbohydrate diet and 15-20% in the strictly low carbohydrate diet with a minimum of 50 g carbohydrates/day. A diet with less than 50 g carbohydrates/day is usually called very low carbohydrate diet or ketogenic and will not be tested in this study. Those who wish to participate and meet the inclusion criteria (and none of the exclusion criteria) will be randomized to one of the three diets. The duration of the intervention is 6 months after which the participants will be able to choose their own diet for another 6 months. The main study visits are at baseline (screening and study start), 3, 6, 9, and 12 months. Shorter visits will be at 3 and 6 weeks. The participants will meet with a study nurse, dietitian and doctor. They will attend two carbohydrate counting courses before the start of the intervention in order to be able to match their insulin to the amount carbohydrates they eat. Participants will receive written materials about their diets with menus and recipes for better adherence to the diet. The primary endpoint is the change in insulin requirements within and between groups (for secondary endpoints please see relevant section). For assessing the different endpoints the participants will provide blood, urine and feces samples for lab analyses as well as register their insulin use, blood glucose, diet, physical activity and any blood ketones or hypoglycemia electronically or in written forms. Continuous/flash glucose monitoring (CGM/FGM) will be also used. Dietary assessment and adherence will be based on 3-4 day food diaries before every scheduled study visit.
The investigators will conduct a randomized controlled trial (RCT) to examine group education visits as an innovative and potentially cost-effective approach to transition care delivery, that can be easily integrated into usual diabetes care. Among emerging adults with type 1 diabetes (T1D), the investigators aim to assess the effect of group education visits integrated into pediatric care, compared with usual care on Hemoglobin A1c (HbA1c), adverse outcomes and psychosocial measures after the transfer to adult care. The investigators will conduct a multi-site, parallel group, blinded (outcome assessors, data analysts), superiority Randomized Controlled Trial (RCT) of adolescents with T1D (17 years of age) followed at one of the two university teaching hospital-based pediatric diabetes clinics in Montreal. Interventions will occur over 12-months. Follow-up will be to 24 months from enrollment.
Can a type 1 diabetic adult avoid low glucoses and regain hypoglycemia awareness using a hybrid closed loop insulin delivery system? Involvement is 22 months (13 visits) and includes a 4-week Screening Phase and an 18-month Intervention Phase. Participants will undergo 3 Hyperinsulinemic Clamps done at: Baseline (before starting the device and after completing the screening), 6 months (after using the device 6 months), and after using the device for 18 months. This metabolic testing will allow us to measure improvement in hypoglycemia awareness.
