Filter by:SMART T1D is a research study that offers interactive diabetes education for teens with type 1 diabetes in peer groups led by diabetes nurse educators. Participants in the study will be randomly assigned to either receive three of the group sessions in addition to their routine clinic care or to receive their usual diabetes clinic care.
The overarching goals of this study are to determine whether tubular dysfunction (elevated urine sodium, bicarbonate and amino acids) and injury (elevated kidney injury molecule 1 [KIM-1], neutrophil gelatinase-associated lipocalin [NGAL] and matrix metallopeptidase 9 [MMP9]) exist in diabetic ketoacidosis (age 3-18), whether it is reversible and whether it is related to uricosuria and copeptin. The investigators propose to study a cohort of youth (ages 3-18, n=40) with T1D who have serum and urine collection at DKA diagnosis and 3-month follow-up.
A frequent complication in the management of diabetic ketoacidosis (DKA) in children with type 1 diabetes is rebound hyperglycemia (blood glucose over 180 mg/dL) which increases the risk of re-developing DKA and can lengthen the hospital stay. The investigators want to study whether giving the long-acting insulin glargine (Lantus®) early in DKA management (versus after complete resolution of the DKA) helps prevent rebound hyperglycemia and makes the transition to insulin injections easier. Participants will also have the option to wear a continuous glucose monitor (CGM) during the study to help us understand blood glucose control during and after DKA.
The suggested clinical trial is part of the KidsAP project funded by the European Commission's Horizon 2020 Framework Programme. The project evaluates the use of the Artificial Pancreas (or closed loop systems) in very young children with type 1 diabetes (T1D) aged 1 to 7 years. The suggested trial is a feasibility study to pilot the setup of a large-scale outcome trial and to address the specific needs of this population. The results of the pilot trial will feed into the design of the outcome study. In this study the investigators will compare closed loop insulin delivery using standard strength insulin to closed loop use with diluted insulin in very young children with T1D. Diluted insulin is a standard treatment approach for children with low insulin requirements. The investigators hypothesize that diluted insulin will lead to more stable glucose levels by reducing inaccuracies accentuated by delivery of minute amounts of insulin (frequently less than 0.1U/h [1μl/h with standard strength insulin] in small children compared to 1U/h in adults). These inaccuracies may result from pump plunger micro-jumps, tissues pressure build-up, and infusion set kinking. This study builds on previous and on-going studies of closed loop systems that have been performed in Cambridge in children and adolescents with T1D in clinical research facilities and in the home setting. The study adopts an open-label, multi-centre, multinational, randomised, two-period crossover design contrasting closed loop glucose control using diluted insulin and closed loop using standard insulin strength under free-living home conditions. The two intervention periods will last 3 weeks each with a 1 to 4 weeks washout period in between. The order of the two interventions will be random. A total of up to 30 young children aged 1 to 7 years with T1D on insulin pump therapy will be recruited through outpatient diabetes clinics at participating clinical centres to allow for 24 completed subjects available for assessment in each of the study arms. Prior to the use of study devices, participants and parents/guardians will receive appropriate training by the research team on the safe use of the study pump and continuous glucose monitoring system, and the hybrid closed loop insulin delivery system. Carers at nursery or school may also receive training by the study team if required. During the intervention periods, subjects and parents/guardians will use the closed loop system for 21 days under free-living conditions in their home and nursery/school environment without remote monitoring or supervision by research staff. The primary outcome is time spent in target range between 3.9 and 10.0 mmol/l as recorded by CGM. Secondary outcomes are the time spent with glucose levels above and below target, as recorded by CGM, and other CGM-based metrics. Safety evaluation comprises the tabulation of severe hypoglycaemic episodes.
This is a randomized, active- and placebo-controlled, double-blind trial of MK-5160 in participants with Type 1 diabetes mellitus (T1DM) and Type 2 diabetes mellitus (T2DM). This is a two-part trial, with three panels per part. T1DM (Part 1) and T2DM (Part 2) participants will be given daily fixed doses of MK-5160 in three predefined, increasing doses in each panel, or glargine (active comparator). The primary hypothesis of the trial is that at a dose with sufficient safety, the mean steady-state maximum level of glucose infusion rate (GIRmax) after MK-5160 administration in both T1DM and T2DM participants is between 1.5 and 4.5 mg/kg/min.
The purpose of this pilot study is to establish that closed-loop insulin delivery with a target enchanted model predictive control (eMPC)/Health Monitoring System (HMS) algorithms with a trust index of the predicted glucose value is safe and effective, to analyze and learn to improve upon the accuracy of the predicted glucose values, and to collect efficacy data to inform a future larger study.
People with type 1 diabetes often find exercise very difficult to manage, because of the high risk for low blood glucose levels. This can occur very quickly once exercise starts and presents many risks for subjects, such as severe symptoms, confusion, passing out, seizures, and even coma or death in very severe cases. Preventing low blood glucose levels during and after exercise is important because physical exercise is a key component of managing diabetes. It is often hard to correctly adjust insulin infusion rates or doses before exercise as the relationship between exercise and changes in glucose levels in those who have type 1 diabetes is still not fully understood. Therefore, the investigators propose this study to further our understanding in this area. This study is designed to help separate the effects of insulin from those of muscle work (non-insulin effects) on the changes in blood glucose levels during aerobic exercise. The main hypothesis is that the non-insulin effects occur quickly during exercise and account for the rapid change in blood glucose levels once aerobic exercise begins. These effects can be separated from the slower changes in insulin sensitivity that occur because of exercise, and which account for reduced insulin demand even after exercise has stopped. The investigators will investigate the effects of both moderate and intense aerobic exercise at different levels of insulin in the body to help separate the insulin and non-insulin effects. The investigators wish to recruit 26 subjects to take part in this study. Subjects will be randomly divided into two groups, with 13 in each group. Group 1 will undergo moderate aerobic exercise, while group 2 will undergo intense aerobic exercise. Each subject will repeat the exercise study three times on three separate days at least 2 weeks apart, while having insulin infused at a low, a medium, and a high rate. Subjects will have an IV line placed in each arm, one for drawing blood relatively frequently during the study, and another for infusion of insulin, glucose, and a special glucose tracer (non-radioactive). Each study lasts about 9 hours. Information from this study will be used to help develop a mathematical model of how glucose changes during exercise in type 1 diabetes. Such a model of type 1 diabetes and exercise will be very useful for adjusting insulin doses in patients who use multiple daily injections of insulin, and can help to guide an automated insulin delivery system, such as the artificial pancreas.
This is a study to assess the effectiveness of CGM (Continuous Glucose Monitor), enhanced by a diabetes management platform (DMP), collectively called enhanced CGM (eCGM), in the care of older patients with T1D. The DMP includes an automated data transfer from CGM, insulin-delivery devices, and activity tracker to a clinical decision support system (CDS) that provides dosing adjustment recommendations based on that data to the healthcare team. In addition, the DMP includes on-demand education for patients and caregivers, and an interface for communication between providers, patients, and their caregivers.
Islet Transplantation is a procedure used in people with difficult to control Type 1 Diabetes. Insulin producing cells (islets) are isolated from a deceased donor pancreas. After the cells are carefully isolated from the donor pancreas, the islets are transplanted into the recipient's liver. These transplanted islets may produce insulin. One of the challenges with islet transplant is the death of some of the transplanted islets due to inflammation, oxidative stress and exposure to diabetogenic immunosuppressive agents associated with islet functional impairment and graft loss, especially linked to the use of calcineurin inhibitors, including tacrolimus (Tac). Antiaging glycopeptide (PKX-001) is a small, stable, synthetic replica of antifreeze proteins (AFPs), which naturally occur in Arctic and Antarctic fish and have been shown protecting cells against harmful conditions. PKX-001 is a new drug that has been shown in lab studies to help islet cells survive isolation and keep them healthy and functioning. Most importantly, animal studies have shown that islets treated with PKX-001 were protected from the immunosuppressant (Tac) toxicity and retained their function in animals receiving islet transplant. This study will involve up to 10 participants from the islet transplant waiting list at the Clinical Islet Transplant Program. All participants will receive islets treated with the medication PKX-001. PKX-001 will be used only in the islet preservation process, and will not be given to participants as medication. The purpose of this study is to confirm the safety of transplantation of PKX-001 treated islets and to evaluate the cytoprotective capacity of PKX-001 in islet transplantation, especially its capacity to protect against Tac induced graft dysfunction.
Due to early diagnosis (<20yrs of age) of Type 1 Diabetes, patients face longer duration of disease and greater glycemic exposure which makes them more vulnerable towards chronic complications. The aim of this study is to investigate the prevalence and incidence of micro and macro-vascular, pulmonary complications and patterns of growth failure in approximately 500 Type 1 Diabetes patients enrolled at Diabetes Unit, King Edward Memorial Hospital Research Centre. Then follow up of 100 participants who are above 15 years of age at baseline will be done after 2 years to document incidence and progression of complications. This will contribute in assessing the public health burden of complications of Type 1 Diabetes. Factors associated with prevalence of complications will be investigated. This risk factor analysis could aid in further modifying current prevention and treatment recommendations of these complications. Results of this study could modify current clinical practice.
