Active clinical trials for "Diabetes Mellitus, Type 1"

The purpose of this study is to assess the safety and tolerability of allogeneic mesenchymal stem / stromal cell therapy in individuals with chronic kidney disease.

Low Carbohydrate Diet (LCD) (< 130 g of carbohydrate per day) and ketogenic diet (< 50 g of carbohydrate per day) are popular among patients with type 1 diabetes (T1D). In most cases, LCD allow a better glycemic control and a important decrease of insulin requirements that cannot, however, be the sole result of low carbohydrate intake. However, due to the increase production of ketone bodies and the decrease of the insulin/glucagon rate, this diet is not without risk in T1D patients and some of them develop ketoacidosis. Type 1 diabetes is a autoimmune disease defined by the destruction of the pancreatic beta cells by the effector T cells, in condition of low regulatory T cells (Tregs). Indeed, some nutrients could regulate the plasticity and the function of Tregs, and be involved in the control of some autoimmune diseases in animals models thanks to a direct effect on immune cells of the digestive tract or an indirect effect by microbiota modulation. The study hypothesises that LCD may be able to restore residual insulin secretion in some patients by modulating immunity. The metabolic mechanisms leading to the effects described in patients with T1D patients under LCD have not been studied : in particular, there is no data on the evolution of the residual insulin secretion and no immunological parameter has been studied on these patients.

This study is evaluate the superior efficacy of a Continuous Glucose Monitor (CGM)-based advisory system in Type 1 Diabetes Mellitus (T1DM), as compared to Sensor Augmented Mode (SAM) therapy, and with characterizing the impact of psycho-behavioral factors on system performance, which will enable system individualization and lead to automated adaptation of advice delivery to optimize glycemic control and reduce the system's psychological impact.

This study proposes to examine the impact of time of day (morning versus afternoon) on the variability of blood glucose responses to high resistance exercise in a single group of patients with type 1 diabetes. Participants will be asked to wear a continuous glucose monitor during the 3 weeks of testing. During the six exercise sessions (three in the morning while fasted and three in the afternoon), participants will complete the same resistance exercise protocol.

Adolescents with Type 1 Diabetes (age 13-18 years, T1D duration >6 months managed on insulin) and poor glycemic control will wear a blinded CGM to obtain baseline data. After assuring adherence to CGM wear, participants will receive a non-blinded CGM and will share their blood glucose levels with the study team. Clinical personnel will remotely monitor patients in real-time for 3 months and communicate regularly over secure text messaging with participants and their parents. Following active remote monitoring, the participants will wear a non-blinded CGM for 3 months. Primary outcome assessment will be the change in HbA1c after 3 months of real-time remote continuous glucose monitoring.

The hypotheses to be tested in this application is: GLP-1 will acutely protect arterial endothelial function and reduce pro-atherothrombotic and pro-coagulant effects of repeated hypoglycemia in T1DM.

The transfer of young people with type 1 diabetes (T1D) to adult care occurs during a critical period of life, while many young people with T1D have unsatisfactory glycemic control. The preparation to take over responsibility for their health and self-care as well as increasing their participation in care are important aspects for strengthening people's own ability, an important component of person-centered care. STEPSTONES-DIAB aims to evaluate the effectiveness of a person-centred transition program for adolescents with T1D to empower them to become active partners in their care. The study is conducted at two hospitals in Stockholm, Sweden where 140 patients will be randomized to either a structured, person-centered transition program over a 2.5 -year period or to usual care. Outcome measures is empowerment, participation and responsibility in care, health status, glycemic control as well as the participants' experiences of care during transfer.

The scientific goal of this study is to examine the effects of a ketogenic diet on hypoglycemia tolerance and brain function in people with type 1 diabetes mellitus (T1D) and to clarify the mechanistic role of ketones in this process. Glycemic management of T1D is typified by alternating periods of hyper- and hypo-glycemia. Because brain metabolism under usual conditions depends on glucose, acute hypoglycemia leads to immediate complications including impaired cognitive function and a counter-regulatory hormone response. Recurrent hypoglycemia is associated with functional and structural changes in the brain and contributes to the cognitive decline observed in individuals with diabetes. The state of nutritional ketosis (as it occurs during fasting or when following a ketogenic [very low carbohydrate] diet) may protect against these acute and chronic complications. As the body relies on fat metabolism, ketone bodies build up and provide an alternative fuel for the brain. Studies during hypoglycemia have shown better cognitive function and less hypoglycemia symptoms in the setting of nutritional ketosis or with ketone administration. This physiological benefit may have special relevance for people with T1D who experience hypoglycemia frequently. To date, no mechanistic studies have examined brain effects of nutritional ketosis in T1D; nor have any trials explored the potential relevance of this for diabetes care.

The investigators want to study the impact CGM (continuous glucose monitoring) has on patients glycemic control as determined by time in range (TIR 70-180 mg/dL) in the Diabetic Kidney Transplant population.

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).
