Additional Autoimmune Diseases With Type 1 Diabetes in Pediatrics at Diabetes Diagnosis and During Follow-up

Conditions
Autoimmune Diseases
Type 1 Diabetes
Hashimoto Disease
Celiac Disease
Vitiligo
Graves Disease
Addison Disease
Registration Number
NCT04789993
Lead Sponsor
Central Hospital, Nancy, France
Brief 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.
