About this study
Do patients with eosinophilic esophagitis have baseline increased esophageal mucosal impedance? And will treatment that reverses esophageal eosinophilia in patients, correct abnormalities in mucosal impedance?
Participant eligibility includes age, gender, type and stage of disease, and previous treatments or health concerns. Guidelines differ from study to study, and identify who can or cannot participate. If you need assistance understanding the eligibility criteria, please contact the study team.
See eligibility criteria
- Adults ages 18-90 undergoing clinically indicated upper endoscopy
- Patients with EoE, defined as dysphagia with histologic finding of greater than or equal to 15 eosinophils per high powered field on esophageal biopsy despite at least 6 weeks of twice daily proton pump inhibitor therapy
- Patients undergoing clinically indicated upper endoscopy for indications other than dysphagia or GERD with normal appearing esophageal mucosa.
- Medical conditions such as severe heart or lung disease that preclude safe performance of endoscopy
- Patients with conditions known to be associated with esophageal eosinophilia, including Crohn’s disease, Churg-Strauss, achalasia, and hypereosinophilic syndrome
