  1. Which one of the following statements regarding esophageal eosinophilia is correct?
    • A. Isolated esophageal eosinophilia is commonly found in gastroesophageal reflux disease (GERD), eosinophilic esophagitis (EoE), and proton-pump inhibitor-responsive esophageal eosinophilia (PPI-REE).
    • B. Esophageal eosinophilia does not occur in systemic disorders.
    • C. Esophageal eosinophilia occurs only in EoE.
    • D. The different conditions causing isolated esophageal eosinophilia can be distinguished based on the eosinophil count and other morphological features.
  2. Which one of the following statements regarding the diagnosis of EoE is correct?
    • A. EoE is seen more commonly in females.
    • B. The finding of fixed rings, longitudinal furrows, white exudates or plaques, and esophageal lacerations induced by the passage of the endoscope are pathognomonic and diagnostic of EoE.
    • C. The finding of ≥15 eosinophils in at least one microscopy high-power field on esophageal biopsy after a proton pump inhibitor (PPI) trial is consistent with the diagnosis of EoE in the appropriate clinical setting.
    • D. In addition to esophageal biopsies, biopsies of the gastric antrum and duodenum should be obtained in all patients.
  3. Which one of the following statements regarding the management of EoE is correct?
    • A. Prednisone is the first-line pharmacologic therapy for the treatment of EoE.
    • B. Esophageal dilation in EoE patients carries the same perforation rate as dilation for other benign diseases.
