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
