Eosinophilic oesophagitis and coeliac disease: Is there an association?

Abstract

Aim: To report a series of 17 children affected by eosinophilic oesophagitis. Six of them also received a diagnosis of coeliac disease. Methods: Seventeen children with history of dyspeptic symptoms were investigated. Results: Six patients (M/F:2/4; mean age ± s.d.: 5.6 ± 1.3 years, range: 4-7 years; Group A) affected by eosinophilic oesophagitis also received a diagnosis of coeliac disease. The other 11 children (M/F:10/1, mean age ± s.d.:7.5 ± 2.3 years, range: 4-10 years, Group B) were affected solely by eosinophilic oesophagitis. All children underwent a change in dietary regimen. Group A received a gluten-free diet. Group B attempted dietary restriction based on the allergy testing results. After 6 months follow-up, all patients in Group A showed a complete disappearance of symptoms and three of them, who underwent upper gastrointestinal endoscopy, showed histologic remission. Patients from Group B had moderate clinical improvement and in seven of them (64%) a repeated upper gastrointestinal endoscopy showed a statistically significant reduction in eosinophilic infiltration. Conclusions: This is the first reported group of patients with an association between coeliac disease and eosinophilic oesophagitis. To date, it is not possible to exclude that in a subgroup of children with coeliac disease the oesophageal eosinophilic infiltration could be caused by coeliac disease itself. © 2007 The Authors.
