Filter by:This is a pilot, interventional clinical trial to assess the effectiveness and safety of artificial pancreas (AP) using the ARG algorithm closed-loop system in a monitored 3-day period outpatient study. Once the safety of the device has been validated in the open-loop first 3-day period (continuous subcutaneous insulin infusion (CSII) plus continuous glucose monitoring (CGM)) the investigators will move the study to the second 3-day closed-loop period, without carbohydrate (CHO) counting.
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.
This study will examine the effects a Glucagon Receptor Antagonist (GRA), has on Insulin Sensitivity, Cardiovascular risks (CVD), and Ketone body formation in participants with Type 1 diabetes. The participants will complete blood tests, tests to measure energy expenditure, CVD risks, and insulin resistance. These tests will be performed prior to start of treatment and again after 12-weeks of treatment with the GRA (called REMD-477).
Type 1 diabetes (T1D) results from the killing of insulin-producing pancreatic beta cells by cells of the immune system. The study aims to slow the progressive, immune-mediated loss of insulin-producing beta cells that occurs after clinical presentation. The investigators have identified a pathway that is important for immune cells to kill beta cells, and a drug that will block this pathway and prevent beta cell death. This drug, baricitinib, is already in clinical use for rheumatoid arthritis, and is currently in clinical trials for other diseases, including childhood autoimmune diseases. It is hypothesized that baricitinib treatment for 48 weeks will preserve beta cell function in children and young adults with recently-diagnosed T1D. The trial aims to recruit 83 participants aged 10-30 years who have been recently diagnosed with T1D. Two thirds of the participants will be randomly assigned to receive baricitinib, one third will receive placebo. The trial will test if baricitinib can slow the progressive loss of insulin-producing beta cells in these patients. The primary objective is to determine if baricitinib can reduce the loss of meal-stimulated plasma C-peptide, a measure of beta-cell function. Maintaining endogenous insulin in recent-onset T1D improves glucose control and may lead to long-term improvements in glucose and lower rates of serious diabetes complications and death.
An artificial pancreas (AP) is a control system for automatic insulin delivery. Our group has implemented a fading memory proportional derivative controller (FMPD) for use within an AP control system which has been evaluated in clinical studies. However, the long action of insulin (90 minutes for peak action) makes it challenging to control insulin with a classical proportional derivative system. The study described within this protocol is designed to test the effectiveness of a new model-predictive control (MPC) AP that modulates insulin delivery based on estimated activity level. The potential benefit of this type of AP is that it handles exercise not as a discrete event, but it automatically adjusts insulin delivery based on estimated activity level calculated at every 5 minute cycle. This type of algorithm may significantly improve glucose control over our FMPD AP, which is designed only to detect exercise when activity level goes above a threshold for a specific duration of 45 minutes.
The objective of this study was to evaluate a virtual diabetes clinic model, for adults with either type 1 diabetes or type 2 diabetes, that supports integration of CGM into diabetes self-management and use of decision support technology.
The aim of the study is to evaluate the efficacy, safety and feasibility of outpatient-utilization of low-dose dasiglucagon administered via a multi-dose reusable pen injector in preventing and treating mild hypoglycemia in insulin pump-treated people with type 1 diabetes.
The aims of this study are to investigate the short term effects of MUFA alone vs. MUFA plus Polyphenols contained in the extra-virgin olive oil (EVOO) on the postprandial glycemic response in patients with type 1 diabetes and to explore the possible mechanisms through which MUFA alone or MUFA plus Polyphenols contained in EVOO could influence postprandial glycaemia.The intervention will be preceded by two-weeks run-in period during which participants will consume an usual olive oil, fill-in a 7-day dietary food record and practice continuous blood glucose monitoring (CGM) in order to optimize basal insulin infusion values and the insulin-to-glycemic load ratio.The study will be conducted according to a randomized cross-over design. The participants will consume, in random order at a distance of one week from each other, a meal-test seasoned with extra virgin olive oil rich in polyphenols (EVOO + POLY) or a meal-test seasoned with olive oil poor in polyphenols (OO-POLY). Upon fasting and during the 6 hours following the meal, patients will undergo to: 1. Venous blood drawing samples for the evaluation of gastrointestinal hormones, markers of systemic inflammation and oxidative stress. 2. Breath test with 13C-octanoic acid, for the study of gastric emptying. During the experimental period the participants will undergo to continuous glucose monitoring wearing sensors 7 days/week. The results of this study will allow optimizing insulin therapy based on the macronutrient composition of the meal in patients with type 1 diabetes mellitus treated with insulin pump. This will improve glycemic control and quality of life of these patients and reduce the risk of developing chronic diabetes complications.
Observational cross-sectional multicenter study about clinical efficacy of insulin pumps in type 1 diabetes mellitus patients.
Recently, there has been an increased interest in limiting carbohydrates (CHO) intakes for improving long-term health. Low CHO (<30% energy from CHO) and very low CHO high fat (VLCHF; 10% CHO, 75% Lipid) diets are being advocated among people living with diabetes given their almost immediate favorable impact on post-prandial blood glucose levels and on hemoglobin A1c that have been reported by users. Adoption of these diets are met with reluctance by healthcare professionals due to the lack of information on their safety. Concerns include the impact on hypoglycemia frequency and glucagon response to hypoglycemia, diabetic ketoacidosis, lipid profile, liver function insulin dose adjustments when adopting them in the context of type 1 diabetes (T1D). Through a series of interviews, people with diabetes following a VLCHF reported that the lack of support from HCPs often leads to hiding the fact that they have adopted a VLCHF diet. This is an important source of concern that can lead to additional safety issues. The goal is to fill an important knowledge gap about the effectiveness, benefits and risks of low CHO and VLCHF diets for people with T1D. The primary objective is to compare the percentage of TIR of adults with T1D following a low-CHO diet or a VLCHF diet versus a control diet for 12 weeks. The secondary objectives are (1) to evaluate efficacy of glucagon in correcting hypoglycemia in the context of restricted carbohydrates intakes; (2) to evaluate changes in HbA1c at 12 weeks and glucose fluctuations and % of time in hypoglycemia at 6 weeks and 12 weeks of control diet, low-CHO diet or VLCHF diet; (3) to compare key cardiometabolic risk factors (body composition, blood lipids, blood pressure and liver inflammatory markers and function) at 6 weeks and 12 weeks of control diet, low-CHO diet or VLCHF diet; (4) to evaluate the effect of restrictive CHO diets (low-CHO and VLCHF) on the composition of the intestinal microbiota (optional).
