Celiac disease associated with autoimmune hepatitis and autoimmune hyperthyroidism

Although celiac disease (CD) may occur in patients with other immune-mediated disorders, its coexistence with multiple autoimmune diseases is not frequently described. We report the case of a 23-year-old woman referred to our centre because of jaundice and diarrhoea, who was diagnosed with CD in childhood. She complied with a gluten-free diet until puberty. Laboratory tests and liver biopsy were performed to establish the diagnosis of autoimmune hepatitis. Her thyroid- specific peroxides levels and thyroid gland function tests were altered as well, indicating the presence of an autoimmune disorder of the thyroid gland. Immunosuppressive treatment led to normalization of transaminases levels and bilirubin. In conclusion, other autoimmune diseases should be ruled out in patients with CD.
