Active clinical trials for "Diabetes Mellitus, Type 1"

A brief, nurse-led educational intervention using motivational interviewing substantially improved general and disease-specific self-management skills in youth with type 1 diabetes.

There is clear evidence that regular exercise improves wellbeing and reduces the risk of diabetes related complications in people with type 1 diabetes. However, many people with type 1 diabetes do not exercise regularly. The primary reason for this is fear of hypoglycaemia and loss of glycaemic control associated with exercise. This loss of glycaemic control is associated with traditional moderate intensity continous aerobic exercise advocated in the guidelines for exercise in people with type 1 diabetes. Recent work (unpublished) from our lab suggests high intensity interval training (HIT) may reduce the risk of hypoglycaemia in people with type 1 diabetes, however stronger evidence is needed before firm conclusions can be drawn. Therefore, the aim of this study is to determine the effects of HIT on glycaemic control in people with type 1 diabetes compared to no exercise and traditional moderate intensity continous exercise. 24 people with type 1 diabetes will be recruited to complete a randomised counterbalanced cross over study comparing 3x 2-week interventions periods. During these intervention periods participant will maintain their habitual lifestyle but complete either no exercise (control), traditional moderate intensity continous exercise or high intensity interval training. Throughout the intervention periods participants glycaemic control will be monitored using a flash glucose monitor.

Type 1 diabetes is an autoimmune disease that requires daily treatment with insulin. The use of subcutaneous pumps for continuous insulin delivery has been an important advance for diabetic patients. The evolution of technologies through the miniaturization of insulin pumps and the advent of continuous glucose sensors has made it possible to understand the development of the artificial pancreas. Several teams are working on the development of an artificial pancreas with considerable progress in closed-loop insulin delivery, particularly during the night. The Laboratory of Digital Sciences of Nantes has developed a new bio-mathematical model describing the glucose-insulin dynamics, closer to the physiological reality of patients with type 1 diabetes. This model allows firstly to identify the parameters of flexible insulin therapy (basal rate, insulin sensitivity, carbohydrate ratios). The objective of this study is to test the relevance of this bio-mathematical model to help the physician identify the parameters of flexible insulin therapy (basal rate, insulin sensitivity, carbohydrate ratios).

Adolescence is a period of intense physiological, psychological and social change. It can be a challenging period for young people with Type 1 diabetes and is associated with worsening blood sugar control and care disengagement. The investigators have co-designed with young people a psychologically modelled educational programme - Youth Empowerment Skills (YES), which aims to facilitate a positive adaption to living with diabetes while improving knowledge and self-management behaviours. Integrated programme components include social and peer-based learning, immersive simulations, and an outreach youth worker. The aim of this study is to test the feasibility of the YES programme (acceptance, implementability, recruitment and completion), and estimate its efficacy in relation to metabolic and psychosocial outcomes. The investigators will recruit young people with Type 1 diabetes and conduct a feasibility randomised controlled trial (waiting-list design) with integrated process evaluation. Sixty young people will be randomised to either YES intervention or waiting-list control and evaluate outcomes at 6-months; at this point the waiting list participants will be offered the YES intervention with further follow-up at 12 months.

Patients with type 1 diabetes are recommended to perform at least 150 minutes of accumulated physical activity each week, however fear of hypoglycaemia is a well-known barrier to exercise in these patients. Previous experimental studies have almost exclusively focused on investigating cardiovascular effects of hypoglycaemia under resting conditions, however other underlying circumstances prior to or during a hypoglycaemic event, (e.g. exercise) are rarely discussed in the literature but might, nevertheless, be of significant clinical importance. In this study, the investigators aim to investigate the QT interval dynamics and prothrombotic factors during exercise-related hypoglycaemia in comparison with hypoglycaemia under resting conditions, in patients with type 1 diabetes. Fifteen patients with type 1 diabetes will be recruited for a crossover study including two test days, a combined euglycaemic- hypoglycaemic clamp combined with an exercise session and an euglycaemic- hypoglycaemic clamp during bed rest, respectively. Furthermore, the participants will be schedueled for a 24-hours followup visit after each test day for the purpose of investigating prolonged prothrombotic effects of hypoglycaemia. Patients will be randomised 1:1 to start with the combined exercise-clamp or the resting-clamp. The two test days will be separated by at least 4 weeks to minimise carry-over effects. A group of fifteen healthy individuals with normal glucose tolerance matched for age, gender and body mass index, will be recruited for a single blood test aiming to compare baseline coagulation status with patients with type 1 diabetes.

The main objective of this clinical trial is to study the metabolic effects of intravenous infusion of the ketone body, 3-hydroxybutyrate (3-OHB), in patients with type 1 diabetes and healthy control subjects. Moreover, the investigators plan to examine regulatory mechanisms of 3-OHB that may be related to diabetic ketoacidosis. The hypotheses are: 3-OHB related inhibition of lipolysis is impaired in patients with type 1 diabetes. Intravenous infusion of 3-OHB affects signaling pathways involved in the metabolic regulation in patients with type 1 diabetes and healthy controls. 3-OHB infusion improves cardiac function in patients with type 1 diabetes and healthy controls. The effects of 3-OHB will be investigated by isotopic tracers examinations, fat and muscle biopsies and blood samples. To evaluate effects on cardiac function echocardiography will be performed.

Type 1 Diabetes (T1DM) is a common chronic illness in children which presents difficult and often stressful management concerns for parents. As children approach adolescence, this burden increases with the desire for independence and self-management. No tool exists that addresses in a user friendly, easy to access and socio-culturally appropriate way, the psychosocial needs of parents as they move through this transition. This program targets the parents to help them at the very point where this transition is occurring.

A single-arm, multi-center, clinical study to assess the safety profile of the Tandem t:slim X2 with Control-IQ system in children with T1D aged 2-6 years old under free living condition

This study is examining whether the Klue app is effective in detecting missed or late meal boluses in patients with Type 1 diabetes. The app is programmed onto an Apple Watch and will detect potential missed boluses from hand motion. It will send text alerts to the user asking if they have bolused. This is a pilot study and will assess whether there is a change in the number of missed meal boluses in the two weeks prior to each visit. If the findings are significant, this software can be integrated in future closed-loop algorithms for automatic insulin delivery.

Feasibility study, comparing experimental treatment (DBLHU closed-loop system) with reference treatment (Low Glucose Predictive Suspend system) in 7 patients going through a series of N-of-1 trials. Each N-of-1 trial consists in a prospectively planned, multiple crossover study in a single individual. Two blocks of two periods of four weeks each (closed loop or open loop) will be conducted. Within each block, the sequence closed loop-open loop or open loop-close loop is randomized. Outcomes will be analyzed on the third and fourth weeks of period. A remote monitoring system managed by specialized nurse on behalf of diabetologist, is provided in closed-loop session. An extension period of 48 weeks with the DBLHU System (closed-loop condition) will be performed at the end of the crossover study phase in real life conditions (without remote monitoring).
