Prevalence of atopic comorbidities in eosinophilic esophagitis: A case-control study of 449 patients

To the Editor: Eosinophilic esophagitis (EoE) is a chronic, immune-mediated esophageal disease characterized by symptoms of esophageal dysfunction in combination with evidence of eosinophil-predominant esophageal inflammation.1 EoE has been closely linked with a personal and family history of atopic disorders, including asthma, eczema, rhinitis, and food allergies. However, the prevalence of atopic disease in patients with EoE varies widely between studies, as estimates have mostly been based on small cohorts.
