Clinical Patterns and Outcomes of Eosinophilic Esophagitis in Children and Adolescents at a Tertiary Care Center in Lebanon

BACKGROUND: Studies on the clinical presentation of eosinophilic esophagitis and its outcome in children in the Middle East and North African region are scarce. The aim of this 10-year retrospective study was to describe the common clinical manifestations, endoscopic and histological findings, and the response to medication and dietary intervention in children and adolescents with eosinophilic esophagitis. METHODS: This study was a retrospective chart review of patients aged 6 months to 18 years who attended the Pediatric Gastroenterology clinic at the American University of Beirut Medical Center between 1 January 2013 and 30 June 2023 and who were diagnosed with eosinophilic esophagitis. RESULTS: A total of 15 patients met the inclusion criteria. The median age at diagnosis was 9 years. Male patients accounted for 73% of our cohort. The most frequent presenting symptoms were dysphagia (80%) and choking (47%). The esophagus appeared normal in 33% of subjects despite histologic confirmation of disease, highlighting the importance of routine biopsies. Adherence to therapy was variable, with 73% of subjects reporting symptom improvement following initial therapy, even in cases where histology remained active. This pattern suggests that symptomatic improvement alone may not reliably reflect disease control and underscores the importance of objective monitoring through follow-up biopsy. CONCLUSIONS: The recognition of manifestations of eosinophilic esophagitis in children, early diagnosis, and strict adherence to the diet and medication are essential to prevent long-term complications. In a resource-constrained country like Lebanon, the management remains challenging in view of the burden of dietary restrictions and high cost of procedures and biologics. Socioeconomic feasibility and long-term adherence to diet and medication is as critical as pharmacologic efficacy in determining outcomes in pediatric patients.
