BACKGROUND: Eosinophilic oesophagitis is an inflammatory condition characterized by a dense eosinophilic infiltrate. The migration of eosinophils into the oesophagus is influenced by cytokines such as IL-5, IL-13 and eotaxin-3. The aim of this study was to evaluate changes in the cytokine expression profiles (IL-5, IL-13 and eotaxin-3/CCL26) in children after topical steroid treatment. METHODS: a prospective case-control study was performed in 23 paediatric patients (age 5-16 years) with a histological diagnosis of eosinophilic oesophagitis. Histological evaluation and cytokine levels assay (IL-5, IL-13 and eotaxin-3/CCL26) in the proximal and distal oesophagus were performed before, and after 8 weeks of topical budesonide. Data were compared with a matched healthy control group. RESULTS: quantitative expression levels of IL-5, IL-13 and eotaxin-3 were significantly higher in the eosinophilic oesophagitis group both compared to healthy subjects (p<0.0001). A significant reduction of the eosinophil infiltrate as well as of IL-5, IL-13 and eotaxin-3 mucosal profiles was observed after steroid treatment both at the proximal and distal oesophagus (p<0.0001). CONCLUSIONS: IL-5, IL-13 and eotaxin-3/CCL26 are significantly over-expressed in the oesophageal epithelium of children with eosinophilic oesophagitis. Topical steroid treatment (inhaled and swallowed budesonide) can induce clinical response with partial mucosal remission. Copyright © 2014 Editrice Gastroenterologica Italiana S.r.l.

The migration of eosinophils into the oesophagus is influenced by cytokines such as IL-5, IL-13 and eotaxin-3. The aim of this study was to evaluate changes in the cytokine expression profiles (IL-5, IL-13 and eotaxin-3/CCL26) in children after topical steroid treatment. METHODS: a prospective case-control study was performed in 23 paediatric patients (age 5-16 years) with a histological diagnosis of eosinophilic oesophagitis. Histological evaluation and cytokine levels assay (IL-5, IL-13 and eotaxin-3/CCL26) in the proximal and distal oesophagus were performed before, and after 8 weeks of topical budesonide. Data were compared with a matched healthy control group. RESULTS: quantitative expression levels of IL-5, IL-13 and eotaxin-3 were significantly higher in the eosinophilic oesophagitis group both compared to healthy subjects (p<0.0001). A significant reduction of the eosinophil infiltrate as well as of IL-5, IL-13 and eotaxin-3 mucosal profiles was observed after steroid treatment both at the proximal and distal oesophagus (p<0.0001).
