Clinical Trial Summary

This study aims to describe the prevalence of additional autoimmune diseases and their specific antibodies at type 1 diabetes (T1D) diagnosis, and their incidence rate during follow-up, for children and adolescents. It also aims to describe the characteristics of the pediatric cohort followed since 2014 for type 1 diabetes by one of France's centers of reference for paediatric diabetes.
