Abstract

BACKGROUND/AIMS: Eosinophilic esophagitis (EoE) is a chronic, immune/antigen-mediated esophageal disease, with eosinophilic infiltration limited to the esophagus. A minority of EoE patients respond well to proton pump inhibitor (PPI) therapy alone, and that condition is labelled PPI-responsive esophageal eosinophilia (PPI-REE). The prevalence of PPI-REE among EoE cases is unknown. We aimed to identify clinical manifestations of PPI-REE, and the proportion of PPI-REE among all EoE cases.

METHODS: We reviewed pathology of the 4,075 patients who underwent esophageal biopsy at an institution from March 2003 to July 2015. EoE was diagnosed based on esophageal symptoms and eosinophilic infiltration limited to the esophagus, with ≥15 eosinophils per high-power field. We collected endoscopic and pathologic findings, and clinical features for these patients.

RESULTS: Thirteen (0.3%) patients were diagnosed with EoE. Clinical manifestations were dysphagia (30.8%), foreign body sensation (23.1%), regurgitation (23.1%), cough (15.4%), heartburn (15.4%), nausea (7.7%), dyspepsia (7.7%). The endoscopic findings noted were polypoid lesion (23.1%), whitish plaque or exudate (23.1%), linear furrow (7.7%), concentric ring (7.7%), nodularity (7.7%), erosion (7.7%), and normal (30.8%). Of these patients, five had a favorable course with PPI as monotherapy.

CONCLUSIONS: The proportion of EoE among all patients undergoing endoscopic biopsy was 0.3%. Of those, PPI-REE comprised 38%. Most of the endoscopic findings were atypical or normal when compared to the typical findings in EoE. In conclusion, patients who present with symptoms related to esophageal dysfunction need esophageal biopsy, regardless of the endoscopic findings. Moreover, patients diagnosed with EoE need to be treated first with PPI alone.
