These guidelines provide clinically useful points to guide the management of ASC in children. Taken together, the recommendations offer a standardized protocol that allows effective monitoring of disease progress and timely treatment escalation when needed.

Collagenous gastritis is a rare condition in children. A small proportion of children develop features of the "'adult" phenotype at a very young age. Patients with collagenous gastritis require long-term follow-up and monitoring of their disease. Further randomized clinical trials are needed to establish an effective therapeutic strategy.

This study suggests that follow-up using two serological tests in children with CD on a GFD may obviate the need for repeat mucosal biopsy in the majority of patients. A standardized dietary questionnaire may be useful in identifying patients who require further evaluation.
