Active clinical trials for "Diabetes Mellitus, Type 1"

An observational study to collect data on the efficacy, safety, usability, and quality of life/psychosocial effects of the Loop DIY automated insulin delivery system.

Individuals with type 1 diabetes (T1D) are at greater risk of fracture than non-diabetic subjects. Although the mechanisms underlying bone fragility in T1D are not completely understood, insulin deficiency seems to play a key role. To date, no information is available on the effect of diabetes remission after pancreatic transplantation alone (PTA) on the risk of fractures in T1D individuals with preserved kidney function. The overall objective of this retrospective cohort study is to evaluate the effect of T1D remission after PTA on fracture risk. The primary endpoint will be the difference in fracture incidence (any fracture) between the PTA group and the control group. For the PTA group, the incidence of fractures after transplantation will be considered. Data from patients who underwent PTA at IRCCS San Raffaele Hospital from January 2, 2005 to December 31, 2017 will be compared with age-, gender- and disease duration-matched controls from the pool of outpatients with T1D attending the Endocrinology Unit at the same Institution. Anthropometric, anamnestic, laboratory data and data on the history of fractures and past/current therapies will be collected. With this study, for the first time we will be able to obtain information on the effects of diabetes remission on the risk of fracture. We expect that the remission of diabetes will result in a beneficial effect on the fracture risk.

The investigators aim to further the understanding of environmental factors that may underlie variations in body composition seen in youth with Type 1 diabetes (T1D). Non-caloric artificial sweeteners, broadly consumed in many individuals with T1D, are a modifiable dietary factor that may be associated with negative health outcomes, particularly those relevant to the future risk of diabetes-related complications. Investigators will measure body composition (the amount of fat and muscle in the body and where the fat is stored) using a bioelectrical impedance analysis machine and DEXA scanner. Blood will be drawn for the following labs: HbA1c, lipid panel, comprehensive metabolic panel and leptin. Participants will also answer questions about their diets and consumption of artificial sweeteners.

The main purpose of this study is to compare LY900014 to insulin lispro (Humalog) in participants with type 1 diabetes who are using an insulin pump and have high blood sugar after eating. For each participant, the study will last about two to nine weeks.

Hypoglycaemia or low blood glucose, and its fear are major barriers to achieving optimal glucose control. New technology, such as continuous glucose monitors (CGM), help to better identify hypoglycaemia and develop strategies to avoid it. These devices measure glucose in the skin, rather than in the blood, and provide information not only on how low glucose is, but also for how long. Recent studies showed that over half of episodes of low glucose with these systems are not recognised by people with diabetes, and even people without diabetes have sensor values that are below the current thresholds for hypoglycaemia [ low blood glucose] that we measure with traditional monitors. In this study, the investigators will evaluate the impact of symptomatic as well as asymptomatic episodes of low sensor glucose on a variety of clinical, patient-related and health economic outcomes such as mood, quality of sleep and productivity. The investigators will test different levels and durations of low sensor glucose to identify the one that best matches episodes that are symptomatic to best define hypoglycaemia using these systems. The investigators will also look at factors that influence this such as sleep or activity as well as diabetes management behaviours (such as insulin dosing, carb counting, etc). At the end of this study, the investigators will be able to provide a better definition of clinically relevant low sensor glucose readings that will help inform clinical as well as academic interpretation of CGM data.

In normal physiology insulin is secreted by beta cells into the portal vein. There have been a number of purported benefits among long-term intraperitoneal insulin users. In the present study we will inject ultra-rapid acting insulin into the upper and lower peritoneum under ultrasound guidance and compare it to subcutaneous injection. We will measure glucose, insulin and glucagon following these injections, to assess for benefits in counter-regulatory hormone production and insulin pharmacokinetics.

The "CoDiaM study" examines how diabetes management and outcomes are changing during the COVID-19 pandemic and whether these changes are influenced by socio-demographic factors, health literacy, self-efficacy and perceived social support.

Observational cross-sectional multicenter study about clinical efficacy of insulin pumps in type 1 diabetes mellitus patients.

The aim of this study is to demonstrate the efficacy of an algorithm to anticipate the post prandial glycemic profile in type I diabetic patient.

This is a single-centre, mixed-methods, prospective study in pediatric patients with T1D initiating Control-IQ technology on the Tandem t-slim X2 insulin pump. Primary Objective: To determine pediatric T1D patients' and their parents' perceptions of the impact of Control-IQ on their psychosocial functioning and quality of life.
