Introduction: The relationship between eosinophilic esophagitis (EoE) and gastroesofageal reflux disease (GERD) has not been fully elucidated, as well as the mechanisms of response to proton pump inhibitor (PPI) therapy. Comprehensive assessment of reflux by impedance-pH monitoring could clarify these issues

Aims & Methods: A prospective multicenter study comparing EoE and GERD patients with healthy controls was carried out. Patients were evaluated off - and on- PPI; impedance-pH appraisal included chemical clearance, assessed with post-reflux swallow-induced peristaltic wave (PSPW) index, and mucosal integrity measured with mean nocturnal baseline impedance (MNBI) in the distal and mid esophagus

Results: Sixty consecutive EoE patients entered the study, and were compared to 60 age- and sex-matched healthy controls and to 60 typical GERD cases. Number of total and acid refluxes were higher while PSPW index and distal MNBI were signifi cantly lower in EoE than in healthy controls. On therapy, all reflux parameters and MNBI improved in the 40 PPI-responsive EoE cases but PSPW index was the only variable independently associated with PPI responsiveness (OR 1.143, 95% CI 1.049-1.247, P=0.002). In PPI-refractory patients, number of total refluxes and PSPW index were not modifi ed by therapy. Distal MNBI improved much more in PPI-responsive than in PPI-refractory cases. Off -PPI, MNBI values in mid and distal esophagus were comparably low in PPI-refractory but not in PPI-responsive EoE

Conclusion: Reflux plays a role in the pathogenesis of EoE, more relevant in PPI-responsive cases. PPIs mainly act by improving chemical clearance, i.e. by an anti-reflux action, thus supporting their long-term prescription in PPI-responsive EoE
