[Autoimmune diseases in type 1 diabetes].

According to literature about 30 % of the patients with type 1 diabetes develop further autoimmune diseases. Thyroid dysfunction represents with 15‒30 % the most common disorder, followed by gastritis with 5‒10 %, celiac disease with 4‒9 % and vitiligo with 2‒10 %. Addison's disease seems to be less prevalent. Diagnostic procedures in the course of the comprehensive care for diabetic patients should therefore include screening for further autoimmune diseases.
