Histopathologic Variability in Children With Eosinophilic Esophagitis

Abstract

Significant histologic variability exists among biopsy specimens from pediatric patients with EoE. Using the criterion of>15 eos/HPF, three biopsy specimens achieved a diagnosis of EoE in 97% of patients. Histopathologic changes consistent with EoE can persist following proton pump inhibitor therapy in patients with EoE and gastroesophageal reflux disease when the latter is defined by increased distal esophageal acid exposure.
