Clinical Characteristics, Endoscopic Findings, and Treatment Outcomes in Lymphocytic Esophagitis Compared With Eosinophilic Esophagitis

Lymphocytic esophagitis (LyE) and eosinophilic esophagitis (EoE) are immune-mediated esophageal diseases. Clinical characteristics, endoscopic findings, and treatment outcomes of LyE were compared with EoE. Methods: This was an international retrospective study on adults enrolled at 3 centers in Europe. We recorded clinical characteristics and endoscopy findings at baseline and symptoms, histology, and endoscopy outcomes after treatment of patients with LyE and EoE. Results: Demographics, clinical presentation, comorbidities, and endoscopy findings were largely different in 35 patients with LyE compared with 59 patients with EoE. Proton pump inhibitor response was generally lower in LyE. Discussion: LyE is clinically different from EoE, but differences in treatment response need further investigation.
