PG - 315-22 LID - 10.1159/000342234 [doi] AB - BACKGROUND: Duodenogastroesophageal reflux (DGER) is considered an independent risk factor for complicated reflux disease (gastroesophageal reflux disease; GERD). However, the role of DGER in GERD patients refractory to proton pump inhibitors (PPI) remains poorly understood. METHODS: 85 patients with clinical reflux symptoms and a history of ineffective response to PPIs were enrolled in the study. Patients with elevated reflux measurement (pH and/or Bilitec measurement; n = 47) received pantoprazole 80 mg for 8 weeks. Clinical outcome was defined as response (/=3 symptoms/week). RESULTS: Of the 47 patients with elevated reflux measurement, 30 were classified as responders and 17 as nonresponders. Treatment with pantoprazole resulted in a significant reduction of acidic reflux in both PPI responders and PPI nonresponders. In contrast, DGER was only significantly reduced in the PPI responder group (22.8 +/- 22.8 vs. 6.6 +/- 10.8%; p < 0.05) but not in the PPI nonresponder group (24.5 +/- 18.6 vs. 22.2 +/- 12.7%; p > 0.05). CONCLUSIONS: The presented study firstly describes that nonresponsiveness to PPI is associated with a limited effect of PPIs on reducing DGER. Thus, persistent DGER may play a key role in mediating reflux symptoms refractory to high-dose PPIs. CI - Copyright (c) 2012 S. Karger AG, Basel.
