TrialNet Pathway to Prevention of T1D

Diabetes MellitusType 1

Rationale: The accrual of data from the laboratory and from epidemiologic and prevention trials has improved the understanding of the etiology and pathogenesis of type 1 diabetes mellitus (T1DM). Genetic and immunologic factors play a key role in the development of T1DM, and characterization of the early metabolic abnormalities in T1DM is steadily increasing. However, information regarding the natural history of T1DM remains incomplete. The TrialNet Natural History Study of the Development of T1DM (Pathway to Prevention Study) has been designed to clarify this picture, and in so doing, will contribute to the development and implementation of studies aimed at prevention of and early treatment in T1DM. Purpose: TrialNet is an international network dedicated to the study, prevention, and early treatment of type 1 diabetes. TrialNet sites are located throughout the United States, Canada, Finland, United Kingdom, Italy, Germany, Sweden, Australia, and New Zealand. TrialNet is dedicated to testing new approaches to the prevention of and early intervention for type 1 diabetes. The goal of the TrialNet Natural History Study of the Development of Type 1 Diabetes is to enhance our understanding of the demographic, immunologic, and metabolic characteristics of individuals at risk for developing type 1 diabetes. The Natural History Study will screen relatives of people with type 1 diabetes to identify those at risk for developing the disease. Relatives of people with type 1 diabetes have about a 5% percent chance of being positive for the antibodies associated with diabetes. TrialNet will identify adults and children at risk for developing diabetes by testing for the presence of these antibodies in the blood. A positive antibody test is an early indication that damage to insulin-secreting cells may have begun. If this test is positive, additional testing will be offered to determine the likelihood that a person may develop diabetes. Individuals with antibodies will be offered the opportunity for further testing to determine their risk of developing diabetes over the next 5 years and to receive close monitoring for the development of diabetes.

Metabolic Phenotypes and Heterogeneity in Disease Burden Risk in Type 1 Diabetes

Diabetes Mellitus

This study focuses on individuals with type 1 diabetes (T1D) and seeks to comprehensively study and understand several aspects of T1D including: susceptibility to hypoglycemia (low blood sugar) and improvement in hypoglycemia risk using of advanced diabetes technologies, such as continuous glucose monitoring (CGM); the differences among individuals with T1D in the risk of chronic complications, and minimize the psychosocial impact of T1D.

Kidney Alone Versus Islet-After-Kidney in Type 1 Diabetic Kidney Transplant Recipient.

type1diabetesRenal Failure1 more

Islet transplantation is associated with a benefit on glycaemic control compared to optimized insulin therapy in recent clinical trials. However, there is a lack of evidence concerning the long-term impact of islet transplantation on type 1 diabetic kidney transplant recipients' prognosis. The objective of the study is to assess the impact of islet transplantation in patients with type 1 diabetes and a kidney transplantation on the risk of graft failure. Every type 1 diabetic recipient transplanted with a kidney in France between 2000 and 2017 is included. Patients transplanted with pancreatic islets are compared to controls treated with insulin alone according to a matching method based on time-dependent propensity scores which allow to ensure patients comparability at the time of islet transplantation. Time-dependent propensity scores are built according to variables associated with both the probabilities of being transplanted with islets and the outcome of interest. These variables are assessed by a direct acyclic graph. The primary outcome consists in death-uncensored graft survival, defined by death or return to dialysis. Secondary outcomes include the risk of death, or the risk of death-censored graft survival.

Type 1 Diabetes Prediction and Prevention (DIPP) Study

Type 1 Diabetes Mellitus

The Type 1 Diabetes Prediction and Prevention (DIPP) Study in Finland is a population-based long-term clinical follow-up study established since 1994 in three university hospitals in Finland to understand the pathogenesis of type 1 diabetes (T1D), predict the disease, and find preventive treatment.

Prevalence, Incidence and Characteristics of NAFLD/NASH in Type 1 Diabetes Mellitus

NAFLDType 1 Diabetes1 more

Nonalcoholic fatty liver disease (NAFLD) is a condition characterized by intrahepatic fat accumulation. It is closely related to insulin resistance. To date, it remains unclear whether NAFLD is common in patients with type 1 diabetes or if NAFLD translates into an increased health burden in this population. Screening for NAFLD is challenging due to the limitations of non-invasive diagnostic tools. Liver biopsy remains the gold standard but is not suited for routine screening or clinical studies. Therefore, there is a great demand for accurate non-invasive screening tools that can not only diagnose but also stage NAFLD. This study aims to generate a large cohort of thoroughly characterized type 1 diabetes patients screened for NAFLD using multiple non-invasive tools including MRI, ultrasound, controlled attenuation parameter, and score panels. We aim to generate a biobank to promote a research collaboration network in the field of non-invasive diagnosis of NAFLD. A secondary endpoint is to investigate the potential correlation between the presence of NAFLD and the occurrence of micro-or macrovascular complications in patients with diabetes.

Sexual Dimorphism in Cardiovascular Autonomic Neuropathy in Patients With Type 1 Diabetes

type1diabetes

Sex might interact with cardioautonomic neuropathy (CAN) in the development of macrovascular disease in patients with type 1 diabetes (T1D). The regulation of the autonomic system shows sexual dimorphism, and may contribute to the cardiovascular risk overload in women with T1D. The aims of this project are: A.1) Determining the prevalence of CAN and subclinical atherosclerosis in a large cohort of consecutive patients with T1D as a function of sex (cross-sectional study). A.2.) Addressing the progression of CAN and subclinical atherosclerosis in patients with T1D as a function of sex (longitudinal prospective study). A.3.) Investigating the influence of sex steroids and circulating biomarkers in the development and progression of CAN and subclinical atherosclerosis. Research designs: A cross-sectional design/prevalence screening study determining the prevalence of CAN as a function of sex in 320 consecutive individuals with DM1. A longitudinal prospective study: the cohort of prevalence screening study will be prospectively followed, and the assessment of cardiovascular autonomic function and subclinical atherosclerosis will be repeated over time.
