Background/aims: Eosinophilic esophagitis is a rare allergic disease of the esophagus with no published data in Turkish children. Methods: This is an observational study of children diagnosed as eosinophilic esophagitis in our hospital between February 2009 and January 2011. We retrospectively analyzed the clinical features, allergic work-up, endoscopic and histological findings, and response to treatment. Results: We followed seven patients in this period with a histopathologic diagnosis of eosinophilic esophagitis. The mean age at diagnosis was 5.05 +/- 2.97 years (range: 1-9 years), and four of them were male. The most frequent symptom was gastroesophageal reflux disease-like symptoms (vomiting, regurgitation, and heartburn) (42.9%). Peripheral eosinophilia and high serum total IgE levels were found in four patients (57.2%). Sensitization to food (71.4%) was more frequent than that of aeroallergens (28.6%). Endoscopic findings suggestive of eosinophilic esophagitis were present in four patients (57.2%). Comorbid allergic disease was present in five patients (71.4%). All patients were treated by elimination diet (85.7%) and/or inhaled corticosteroid treatment (71.4%). The mean follow-up period was 12.4 +/- 6.1 months (range: 6-24 months). All but one patient showed complete clinical response to their treatment. No significant side effect was observed during the follow-up period. Conclusions: Eosinophilic esophagitis is a rare gastrointestinal allergic disorder frequently comorbid with other allergic diseases and with different manifestations and response profiles to treatment modalities.
