[Celiac disease and other immunomediated diseases coexistance and influence of clinical course. Case report].

Celiac disease (gluten enteropathy) is chronic immunomediated disorder of gastrointestinal tract in genetically predisposed patients. We present the case of 46 years old man, with already diagnosed several autoimmune disorders, such as: diabetes mellitus LADA type, Graves-Basedow disease and vitiligo. Despite treatment of the above diseases, diarrhea and persistent abdominal pain was observed. Diagnosis of gluten enteropathy based on serology and histological evaluation of biopsies from distal part of duodenum enabled us to introduce gluten free diet, which contributed to attenuation of symptoms and better control of glucose serum levels. We think, that celiac disease should be taken into the consideration in differential diagnosis of chronic diarrhea and persistent abdominal pain, especially in patients with coexisting autoimmune diseases.
