INTRODUCTION:: A multicenter study with a limited sample size found that absence of esophagitis, presence of functional digestive disorders, and overweight were associated with proton pump inhibitors (PPI) failure. AIM:: To assess clinical and reflux patterns associated with PPI-responsiveness. MATERIALS AND METHODS:: Patients with typical gastroesophageal reflux disease (GORD) symptoms had 24 hours pH-impedance monitoring off therapy. Responders had 25 kg/m) and the presence of esophagitis (P=0.019 and 0.043, respectively). CONCLUSIONS:: We confirm that no reflux pattern demonstrated by 24 hours pH-impedance monitoring is associated to PPI response in GORD patients. Presence of esophagitis in the whole population and overweight in patients with pathologic GORD, but not dyspepsia, are strongly associated with PPI-responsiveness.
