Observational study finds low eosinophilic esophagitis prevalence in adults with reflux symptoms, indicating predictors such as allergy history and PPI nonresponsiveness.
Key Points
Eosinophilic esophagitis was diagnosed in only 4 out of 350 screened patients, indicating a low prevalence.
Allergy history was found in 75% of eosinophilic esophagitis patients, significantly higher than non-EoE subjects.
The method used included esophagogastroduodenoscopy and targeted biopsies to assess eosinophil levels.
Recognizing predictors like elevated eosinophils and PPI nonresponse may enhance diagnosis in clinical settings.
