ABSTRACT
Background: Type 1 diabetes mellitus and celiac disease share common genetic and immunological aspects and celiac disease is more common among type 1 diabetic patients. Aim: To determine the frequency of anti endomysial and anti transglutaminase antibodies among patients with type 1 diabetes. Material and Methods: Anti endomysialantibodies determined by indirect immunofluorescence an anti transglutaminase antibodies determined by ELISA were measured in 410 serum samples of patients with type 1 diabetes. Results: Seventy one samples (17 percent) had positive anti transglutaminase antibodies. Among these, 17 had also positive anti endomysial antibodies. In 11 of these 17 patients, the presence of celiac disease was confirmed. Conclusions: Among patients with type 1 diabetes mellitus, the frequency of celiac disease is three times higher than in the general population.
