Automated Fully Closed-Loop Insulin Delivery in Type 1 Diabetes With Ultra-Rapid Lispro (ACOLYTE...
Diabetes MellitusType 1The main objective of the study is to determine whether fully closed-loop insulin delivery using ultra-rapid acting insulin lispro will improve glucose control compared to standard lispro under conditions mimicking missed meal bolus. Ultra-rapid acting lispro (Lyumjev) is a novel formulation of insulin lispro in which two additional excipients (citrate and trepostinil) have been added, resulting in accelerated initial absorption and more than double the glucose lowering effect in the first 30 minutes after subcutaneous administration using insulin pump. To date, no randomised controlled trial involving fully closed-loop in type 1 diabetes has been performed to evaluate the benefit of Lyumjev over standard lispro. This is an open-label, single-centre, two-period, randomised, crossover study. The study involves two 12-hour in-patient stays at the clinical research facility during which glucose levels will be controlled by the Cambridge closed-loop system with either Lyumjev or standard lispro. Up to 26 adults with type 1 diabetes treated with insulin pump will be recruited at Manchester Royal Infirmary, aiming for 19 completed participants. During the study days, closed-loop will automatically modulate insulin infusion rate based on real-time glucose sensor measurements. Participants will receive standardised meals with no meal bolus for the lunch time meal during each study day. Primary outcome is the time spent in sensor glucose range (3.9-10.0mmol/l) between 11:00 - 17:00 hrs. Secondary outcomes are the time spent with glucose levels above and below target, and other sensor-based metrics. Safety evaluation comprises assessment of the frequency of hypo and hyperglycaemic episodes.
Stimulated Glucagon as a Biomarker of Hypoglycemic Risk in Type 1 Diabetes
Type 1 DiabetesHypoglycemiaType 1 diabetes (T1D) results from destruction of insulin producing beta cells by the body's own immune system (autoimmunity) causing an individual to lose the ability to make enough insulin to control their blood sugar levels and need to have insulin injections to lower blood glucose levels. Whilst high blood sugar level is a problem for people with Type 1 diabetes, taking insulin medication to lower sugar levels, delayed meals and exercise can all result in dangerously low blood sugar levels (hypoglycaemia). The biological causes of hypoglycaemia, and ways to prevent it are poorly understood. In non-diabetic individuals, a hormone called glucagon is secreted naturally to raise blood glucose levels but it is unclear why glucagon secretion is impaired during hypoglycaemia in individuals with T1D. The aim of this prospective observational study is to test the relationship between a glucagon stimulation test and risk of hypoglycaemia in T1D. It is hoped this research will establish whether this relationship could be used as a blood test and be a clinically useful biomarker of hypoglycaemia risk and, therefore, directly inform clinical care of people with T1D, particularly those with highest risk of hypoglycaemia. Participants will be asked to complete: a Mixed Meal Tolerance Test (MMTT) at Visit 1 or 2 an Arginine Stimulation Test (AST) at Visit 1 or 2 a Light MMTT or repeat AST at Visit 3 (approx 6-7 months of Visit 1) continuous glucose monitoring (CGM) and self-reported time spent in hypoglycaemia will be undertaken for 2 weeks following Visits 1 and 3.
Evaluation of CloudCare in the Treatment of Type 1 Diabetes
Type 1 DiabetesCloudCare is an eHealth application to help health care professionals (HCP) in the management/treatment of type 1 diabetes. The application will automatically check all uploaded glucose parameters from patients glucose monitoring devices and present all these data in a categorized way (using a so called dashboard) to the HCP. In this way the HCP has a direct overview of the condition of her/his patients, and can determine which data request direct action towards the patient and which data do not. It is expected that this system improves outcome and patient experience. In this study this expectation will be studied by measuring the effect of CloudCare on patients' treatment satisfaction, glucose control, HCP satisfaction and the impact on costs.
Slow Digestible Carbohydrates and Exercise in Adolescents With Type 1 Diabetes
Type 1 DiabetesHypoglycemiaIn this within-subject cross-over study, the investigators hypothesize that corn-starch based supplements taken prior to exercise will decrease the risk of delayed hypoglycemia in adolescents with T1D, improve performance during exercise, and decrease glycemic variability during exercise.
Real-life Data From Diabetic Patients on Closed-loop Pumps
Type 1 DiabetesTo evaluate, in real life, the effect of closed-loop devices on the improvement of glycemic control in diabetic patients managed in the endocrinology departments of secondary care hospitals.
Type I Diabetes and Non-surgical Periodontal Treatment
Type 1 DiabetesPeriodontitis5 moreCurrent evidence suggests a bidirectional association between periodontitis and diabetes. Periodontal therapy improves short term HbA1c levels and is safe to perform. Most studies are focused on type 2 Diabetes. Literature about the correlation between periodontitis and type 1 diabetes is scarce, since no randomized clinical trials have been performed. The objective of the present clinical investigation is to evaluate the effects of nonsurgical treatment of periodontal disease on glycemic variability in patients with type 1 diabetes (T1DM). The hypothesis is that nonsurgical periodontal therapy affects glycemic variability in terms of time spent in hyperglycemia.
Lipoprotein Kinetics in T1D
Type 1 DiabetesThe purpose of this research study is to understand how type 1 diabetes (T1D) increases the risk for cardiovascular diseases (heart attack and stroke). To this end, the investigators will compare apolipoprotein and triglyceride kinetics in people wtih T1D and healthy control participants.
Semaglutide GLP1 Agonists With Degludec Basal-bolus Insulin in Early Type 1 Diabetes to Basal-bolus...
Type 1 Diabetestype 1 diabetes is an autoimmune disease and still, some unknown mechanisms are undiscovered millions of children and adults suffer from this type which need basal-bolus insulin as the classical regimen, and basal-bolus insulin is the best type of treatment is similar to the physiological pattern, so our target and may studies before how to preserve the residual beta cells or postpone the complete destruction or extend the honeymoon stage to improve quality of life, the most challenge at type 1 diabetes is diabetic ketoacidosis which affect the quality of life and risk of death so at our clinical trials using the combination of basal insulin-like degludec as its action extend to 72 hours and has high flexibility and less hypoglycemic events and has an affinity to 99% to albumin so may be considered the most type of insulin is similar to human physiological insulin as 50% of insulin pass through portal circulation so no insulin until now it is mimic the normal physiological insulin but IDeg is the nearest to normal until now, Objective: To compare the efficacy and safety of basal-bolus insulin degludec and semaglutide with regular standard of care versus basal-bolus insulin with regular standard of care in early type 1 diabetic patients. In our study, the investigators will compare 2 groups of early type 1 patients in the age group 18 years to 35 years Protocol and Methodology for a Randomized Controlled Trial of Basal-Bolus Insulin Degludec and Semaglutide with Regular Standard of Care Versus Basal-Bolus Insulin with Regular Standard of Care in Early Type 1 Diabetic Patients Study Design: Randomized, controlled, open-label trial Setting: Outpatient diabetes clinics Participants: Early type 1 diabetic patients (aged 18-35 years) who have been diagnosed with type 1 diabetes for less than 2 years and have a hemoglobin A1c (HbA1c) of 7.0-11%. the tests will be done pre- and post : Anti GAD 65 and anti IA2 HA1C Serum C peptide fasting insulin serum zinc
Dual-hormone Artificial Pancreas Versus Single-hormone Under Exercise and a Meal Challenge
Type 1 DiabetesThe present clinical trial aims to examine alternative strategies for preventing/mitigating hypoglycemic events among adults with type 1 diabetes utilizing a highly personalized control system. This system offers two configurable options: a single-hormone configuration with automatic rescue carbohydrate recommendations (sHC) and a dual-hormone configuration with subcutaneously administered glucagon boluses (dHmG). The main question addressed in this study focuses on determining whether the dHmG outperforms the sHC in terms of minimizing the time spent below the target range and number of hypoglycemic events. Each participant will undergo two 12-hour controlled inpatient studies, including each an unannounced 30-min aerobic exercise session and a meal challenge. The order of these studies, comparing the dHmG to the sHC, will be randomized.
Bone Health in Youth With Type 1 Diabetes
Type 1 DiabetesOsteoporosisThis is an observational study of children and young adults ages 6-20 years with type 1 diabetes and age- and race-matched controls. The investigators will be examining blood and urine hormone levels as well as measures of bone density including DXA and high-resolution peripheral quantitiative computed tomography. The investigators will also be collecting data regarding physical activity via use of wearable accelerometers. The investigators hypothesize that youth with type 1 diabetes will have slower bone accrual and impaired bone microarchitectural integrity compared with non-diabetic controls, and that bones of individuals with type 1 diabetes will not respond as well to physical activity. The investigators hypothesize that poor bone accrual will be associated with sub-optimal glucose control as well as lower levels of insulin-like growth factor 1.
