BeAT1D: Benign Autoimmunity and Type 1 Diabetes
National multi-center non-interventional case-control cohort study with collection of biological samples to characterize the autoimmune T and B lymphocytes involved in the development of type 1 diabetes.
Inclusion: Type 1 diabetes: type 1 diabetes, as defined by hyperglycemia and long-term insulin therapy started within 6 months from clinical onset; and/or the presence of at least one anti-islet auto-antibody; Other forms of diabetes or autoimmune endocrinopathy: other forms of diabetes (e.g. type 2, ketosis-prone, familial, secondary, immunotherapy-induced diabetes); and/or other autoimmune endocrinopathies, isolated or multiple; No diabetes: absence of diabetes or impaired glucose tolerance; absence of tumor, infectious or immune pathologies, or other conditions related to autoimmune or metabolic alterations that may bias the variables under study; Lymphadenectomy planned in the frame of an abdominal surgery: pancreatic lymphadenectomy planned at the occasion of an abdominal surgery for the treatment of an underlying condition.
Exclusion: For all participants: ongoing pregnancy; known HIV/HCV infection; absence of social security coverage; placement under judicial protection; absence of signature of the informed study consent.
