Exploring a predictive model for screening eosinophilic esophagitis in children with dysphagia.

Eosinophilic esophagitis (EoE) is frequently associated with dysphagia and requires esophagoscopy with biopsies for diagnosis, as no reliable diagnostic biomarkers currently exist. While inflammatory indices derived from complete blood counts have been investigated in esophageal dysfunction, their role in screening for EoE remains unexplored. This study evaluates the utility of different predictive models for screening EoE through a diagnostic study of patients <15 years old undergoing esophagoscopy for suspected EoE in a pediatric hospital between 2015 and 2022 (Reg. 3318-0000206).
