[Correspondence] Coeliac disease and dermatitis herpetiformis – Authors’ reply

We appreciate the comments by Giacomo Caio and colleagues and François Rodrigues and colleagues. The topics of potential coeliac disease and dermatitis herpetiformis were omitted from our Seminar1 for reasons related to length and scope. We agree with the principles regarding the management of potential coeliac disease, as outlined by Caio and colleagues, but would like to add two points. First, when assessing a patient who appears to have potential coeliac disease, distinguishing this condition from coeliac disease, in which the diagnosis was missed because of inadequate sampling of the duodenum in relation to the number of specimens submitted,2 exclusion of the duodenal bulb3 or misinterpretation of subtle signs of villus atrophy by a patho-logist is important.
