Effect of pantoprazole in patients with chronic laryngitis and pharyngitis related to gastroesophageal reflux disease: clinical, proximal, and distal pH monitoring results.
Few studies had evaluated the results of proton pump inhibitors on distal and proximal pH recording using a dual-channel probe. The aim of this study was to determine the clinical and pH-metric effect of treatment with pantoprazole 80 mg for 8 weeks in patients with ear, nose, and throat (ENT) manifestations of gastroesophageal reflux disease associated with pathological proximal acid exposure. We conducted a prospective open study. Patients included had to have chronic pharyngitis or laryngitis, and a pathological gastroesophagopharyngeal reflux. All patients received treatment with pantoprazole 80 mg daily for 8 weeks. One week after the end treatment, patients had a second ENT examination and a 24-hour pH monitoring using dual-channel probe. We included 33 patients (11 men, 22 women). A pathological distal acid reflux was found in 30 patients (91%). After treatment, the improvement of ENT symptoms was found in 51.5% of patients. Normalization of 24-hour proximal esophageal pH monitoring was observed in 22 patients (66%). After treatment, the overall distal acid exposure, the number of distal reflux events, and the number of reflux during more than 5 minutes were significantly decreased (respectively: 19.4% vs 7.2% [P < 0.0001], 62.7 vs 28.4 [P < 0.0001], and 10.4 vs 3.9 [P < 0.0001] ). Similarly, in proximal level, the same parameters were significantly decreased after treatment (respectively: 6.8% vs 1.6% [P < 0.0001], 32.6 vs 8.1 [P < 0.0001], and 3.4 vs 0.6 [P= 0.005] ). Treatment with pantoprazole reduced the frequency and severity of gastroesophagopharyngeal acid reflux in patients with chronic pharyngitis and laryngitis.
