Active clinical trials for "Diabetes Mellitus, Type 1"

Eight adolescent and young adult subjects with type 1 diabetes, age 16-24 years, will be recruited for this study on the basis of informed consent. Participants will be invited to attend the Wellcome Trust Clinical Research Facility at Addenbrooke's Hospital, Cambridge, on two occasions. On each occasion participants will arrive at the unit at 9am having controlled their diabetes with short acting insulin for 24 hours and they will remain in the unit until 8am the next morning. During the day, between 9am and 6pm participants will remain fasting and their blood glucose levels will be controlled by intravenous insulin, the dose being determined by 15-30 minute blood glucose estimations. At 1800hr on visit 1 the subjects will be asked to ingest an evening meal enriched by a cold isotope glucose tracer (non radioactive). The variable insulin infusion will be adjusted to allow for the meal in order to achieve good glycaemic control after the meal until 0200hr. From then until 0800hr in the morning the study team will again adjust the infusion rates to maintain normal glycemia until the participants are ready to go home on their normal insulin regimen. On the second visit the protocol will be identical until 1800hr when instead of giving the meal variable amounts of glucose will be infused to ensure the glucose levels are identical to those observed on visit 1. After 0200hr the study will be effectively finished but the study team will continue to vary the insulin infusion to keep blood glucose levels normal until the subjects can go home on their normal insulin regime at 8am. In order to achieve sufficient information to make all the calculations needed other cold isotope glucose tracers will be infused during the study period. These safe non radioactive isotope tracers will enable us to assess glucose being produced by the body, its distribution and utilization. Throughout both study periods the subjects will be monitored very closely by a Clinical Research Fellow, assisted by a Research Nurse, in order to avoid any risk of low blood glucose levels.

The study seeks to evaluate a novel treatment approach for performing continuous real-time glucose sensing and insulin delivery at the same subcutaneous tissue site.

Using radial artery tonometry to study arterial stiffness, the plan is to study a cohort of 65 children with Type I diabetes mellitus. This prospective, crossover study will help determine if there is an acute increase in arterial stiffness in children with Type I diabetes mellitus who do not give extra insulin to cover a meal. This will give more support to show why it is so critical to bolus every time they eat and to bolus on time to decrease cardiovascular consequences of poorly controlled diabetes. The hypothesis is that giving insulin before a meal compared to not giving insulin before a meal will be associated with lower arterial stiffness in children with type I diabetes.

The purpose of this study is to compare a needle-free treatment of hypoglycemia with nasal glucagon (study drug) to a marketed glucagon administered by the intramuscular (IM) route, in participants with type 1 diabetes mellitus (T1DM).

This study aimed to evaluate the levels of interleukin 18 and tumor necrosis factor-alpha (TNF-α) in gingival crevicular fluid (GCF) of children with type 1 diabetes mellitus and gingivitis.

With an increased incidence of pediatric type 1 diabetes (T1D) and a decrease in age at diagnosis, children are exposed to complications such as renal impairment at a very young age. The current biomarker used to diagnose renal impairment is microalbuminuria, but it's a late marker. Early screening is a major issue to reduce T1D consequences. Early glomerular hyperfiltration (GHF) could participate in the development and progression of nephropathy. Hyperfiltration has also been associated with a systemic endothelial dysfunction and with changes in arterial stiffness, suggesting, at least to a certain extent, a state of generalized vascular dysfunction. Diabetes is responsible for very early neurovascular dysfunctions, detectable with techniques to evaluate cutaneous neurovascular interaction. Those should help bringing to light very early microcirculation impairment, particularly precocious endothelial dysfunction (ED). No study about correlation between GHF and ED is currently available. The hypothesis assessed is those of a strong correlation between ED and GHF in children and adolescent with a story of T1D for at least 10 years. This pilot study should allow assessing ED's and GHF's proportions in our population, in order to conduct a larger study to prove, in a prospective way, the prognostic value of ED in the apparition of nephropathy, taking into count other factors such as diabetes duration or stability. This measure could be included in the global evaluation of microangiopathy risk in children and then take action to prevent negative outcomes. The second aspect of this study is the assessment of other functions and metabolisms possibly impaired in T1D: osseous microarchitecture, vitamin D status and precocious evaluation of macro angiopathy through intima media thickness measurement. Long term diabetes in children is associated with shorter and leaner bones, despite a correct mineralization, a reduced bone density and a fracture risk increased six fold. Bone status in the population will be evaluated through the study of bones microarchitecture via HR-pQCT (High Resolution peripheral Quantitative Computed Tomography) on both tibia and radius, dual-energy X-ray absorptiometry (DXA), and bone turn over biochemical markers. Results on bone microarchitecture in a preexisting cohort of healthy children and adolescents will be used to compare results.

Fiasp® is a meal-time insulin that has been available in Sweden since June 2017. This study will investigate the effectiveness of Fiasp® in treating Type 1 Diabetes Mellitus. The study will be based on blood sugar measurements that the participants have uploaded to the Diasend® database and on existing data in their electronic medical records. The study does not require any additional visits to the study doctor.

The current study aims to assess clinical outcomes in adults with type 1 diabetes (T1D) who have switched from traditional multiple daily injection (MDI) therapy to continuous subcutaneous insulin infusion (CSII) therapy with the Omnipod insulin system.

This project will assess self-efficacy levels(SE) ,resiliency and attachment style of adolescent with type 1 diabetes and their caregivers.SE and attachment style of patients and parents will be compared with each other as well as correlated with diabetes management as assessed by A1C and self inventory scale.

Patient participation in decision making about their care promotes patient satisfaction and confidence. Further more, allowing patients to see letters written about them enables trust, encourages patients to be involved in decision making process and allow patient understanding. Little is known about how young people value these letters in the same way. Only one brief questionnaire study focused on adolescent views and found that young people wished to receive consultation summaries. This research aims explore the views of adolescent patients related to consultation summaries that they receive following a doctor's appointment. The investigator will use patients attending a specialist diabetes clinic as our cohort and conduct a qualitative study using focus groups.
