Summary

The previous studies assessing prevalence of coeliac disease in patients with Crohn’s disease have produced conflicting results. Moreover, anti-tissue transglutaminase antibodies which are implemented in the diagnostic scheme of coeliac disease seem to have limited value for the diagnosis in Crohn’s disease patients. So, we would like to share with the readers our experience of the study in 104 Crohn’s disease patients, who were tested for anti-tissue transglutaminase antibodies, anti-tTG, anti-deamidated gliadin peptides antibodies, anti-DGP and anti-endomysium antibodies, EMA. We think that coeliac disease occurs among Polish patients with Crohn’s disease with comparable prevalence to the general population. Moreover, anti-tTG, anti-DGP and EMA seem to be equally valuable for coeliac disease screening in patients with Crohn’s disease.
