Active clinical trials for "Diabetes Mellitus, Type 1"

This observational study aims at finding out if individual with autoimmunity exhibit increased numbers of B cells that express two types (instead of one type) of antibodies, and if B cells of individuals genetically susceptible to autoimmunity display defects in the biological process of tolerance, which removes B cells that participate in autoimmunity.

The Fr1da study aims to assess whether early staging of type 1 diabetes (1) is feasible at a population-based level, (2) prevents severe metabolic decompensation observed at the clinical manifestation of type 1 diabetes and (3) reduces psychological distress through preventive teaching and care.

Dysbiosis is associated with an increased risk of preeclampsia during pregnancy. The microbiome differs between those with and without type 1 diabetes and the cause of type 1 diabetes has been associated with dysbiosis. Increased knowledge of the microbiome and its variation, depending on the state of health during pregnancies complicated with type 1 diabetes, could in the future lead to preventive care and treatments during these pregnancies.

Nonalcoholic fatty liver disease (NAFLD) has been extensively studied in the context of type 2 diabetes mellitus (T2D) due to its higher prevalence and its association with obesity and syndrome metabolic, a well-established risk factor for NAFLD. Although several studies have reported the accumulation of liver fat in patients with type 1 diabetes mellitus (T1D), the prevalence, etiology, and the consequences of NAFLD in patients with T1D are poorly characterized, requiring more studies in this field. In addition, liver involvement at the metabolic level in patients with T1D raises the differential diagnosis between NAFLD and glycogen hepatopathy (GH), a rare complication associated with the poorly metabolic control of diabetes and probably underdiagnosed, since the ultrasound pattern is the same than the NAFLD. The investigators have designed a cross-sectional observational study with the objective of describing the prevalence of metabolic liver diseases (NAFLD and GH) in the population of patients with T1D in the healthcare area of Hospital del Mar and Hospital de Vilafranca, as well as studying the relationship of these pathologies with the degree of metabolic control, the presence of metabolic syndrome and the presence of micro and macrovascular complications.

The T1D Exchange Registry is a research study, conducted over time, for individuals with type 1 diabetes and their supporters. Participants volunteer to provide their data for research (for example, by answering questions in annual surveys). Once enrolled, Registry participants have the opportunity to sign up for other studies on various topics related to type 1 diabetes. To participate, you will be asked to: Read and sign an online informed consent form Take a survey describing specific demographic and type 1 diabetes management information Update your information annually Periodically opt in for additional research opportunities (if you choose), i.e. taking new surveys or uploading health device data

Since February 2019 the first hybrid closed-loop insulin pump, the Medtronic MiniMed 670G system, has been offered to people with type 1 diabetes in Belgium. Despite previous studies, the impact of these new kinds of insulin pumps on glycemic control and patient-reported outcomes (PROMs) is still unclear. Therefore, this study will evaluate the impact of the Medtronic MiniMed 670G, Medtronic MiniMed 780G and Tandem Control-IQ systems on glycemic control and PROMs in people living with type 1 diabetes under real-life conditions. In a multicenter real-world observational study, 350 adults and 100 children with type 1 diabetes who are treated with each of these systems in one of 17 Belgian centers, will be followed for a period of 24 months. The primary endpoint is the evolution of time spent in range (defined as a sensor glucose value between 70 and 180 mg/dL) from before start to 12 months after start of hybrid closed-loop therapy. Since not much is known about the impact of hybrid closed-loop on partners of adults living with type 1 diabetes, an optional substudy (INRANGE-PARTNER) will be performed investigating the quality of life in partners of adults of type 1 diabetes using hybrid closed-loop therapy. More specifically, the substudy will compare the quality of life of partners of type 1 diabetes patients both before and after implementation of hybrid closed-loop therapy.

The purpose of this research study is to find out how bones are affected in children and adolescents with type 1 diabetes (T1D) as compared to children and adolescents without type 1 diabetes.

Type 1 diabetes (T1D) is characterized by absolute insulin deficiency. Although the discovery and application of exogenous insulin has prolonged the lifespan of T1D patients, the chronic diabetic complications caused by long-term poor glycemic control will still reduce patients' quality of life and the overall life expectancy. According to the studies focused on long-term T1D, part of the patients with long disease duration showed resistance to microvascular complications, and several protective factors have been identified. The prevalence of T1D in China is extremely low compared to that in the western world, and little is known about the characteristics of patients with long-term T1D in China. Therefore, this study is designed to collect variable clinical and laboratory features of patients with long-term T1D, explore the risk and protective factors for the development of microvascular complications, and provide reference for the prediction and prevention of these complications.

Observational study about usefulness of intermittently scanned continuous glucose monitoring (isCGM) in the diagnosis of maturity-onset of the young (MODY) patients.

The main goal of the study is to describe the sublingual microcirculation of children with type 1 diabetes mellitus (T1D) with stable and satisfactory treatment of the disease and to compare it with previously measured parameters of healthy children, NCT05324228.
