Abstract
Objectives were to determine the efficacy of empiric treatment with esomeprazole for patients diagnosed with laryngopharyngeal reflux and to determine a treatment paradigm for this patient population. Prospective study. Patients were treated with a once-daily dose of 40 mg esomeprazole for 8 weeks. All patients completed a subjective symptom scale (rating laryngeal symptoms and esophageal symptoms) and scoring of flexible fiberoptic examination before treatment and at 4 and 8 weeks of treatment. Nonresponders (<50% reduction in symptom score) were recommended to undergo 24-hour dual-probe pH study while on a regimen of 40 mg esomeprazole once a day, to evaluate for the adequacy of acid suppression. Thirty patients completed the course of therapy. After 4 weeks of treatment, only 8 of 30 patients had significant improvement of their overall symptoms (8 of 30 improved on laryngeal score, and 11 of 18 improved on esophageal score). At 8 weeks of treatment, 19 of 30 patients had significant improvement on their overall symptoms (18 of 30 on laryngeal score, and 13 of 18 on their esophageal score). Five of seven nonresponders who agreed to be tested had positive findings on pH studies (on medication regimen) at 1 cm above the upper esophageal sphincter. Four of 10 nonresponders improved further after increasing their dosage to 40 mg twice a day. Laryngeal examination scores were statistically improved in responders after 8 weeks of treatment. Laryngopharyngeal reflux symptoms require at least 8 weeks of treatment for significant improvement in the majority of patients. Esophageal symptoms improve sooner. Nonresponders at a daily dose of 40 mg should be treated with a dosage of 40 mg twice daily, and pH study on medication reserved for nonresponders at this higher dose. Laryngeal examination scores showed mild but statistically significant improvement at 8 weeks of therapy in responders.
