Abstract

Objective: Response to acid suppressive therapy varies in patients with extraesophageal esophageal reflux disease (EERD). Inadequate suppression of gastric acid may contribute to the observed differences in the response to the treatment. The aim of this study was to evaluate suppression of gastric acid in EERD patients being treated with acid suppressive therapy. Methods: Charts of patients with EERD who underwent dual channel 24 h esophageal pH monitoring while receiving acid suppressive therapy between January 2002 and June 2004 were reviewed. Suppression of gastric acid was determined based on the number of acid reflux episodes, esophageal acid exposure, and acid clearance time. Results: Twenty patients (12 male, 8 female, age range: 2-19 years) were identified. Esophageal pH monitoring was within normal limits, documenting complete acid suppression in nine patients (45%). Increased numbers of acid reflux episodes were observed in seven patients. In four patients, the number of acid reflux episodes was normal in spite of incomplete acid suppression. However, other abnormal pH monitoring parameters included delayed acid clearance in three patients and increased acid exposure time in three. The majority of patients also showed alkaline reflux. Conclusion: Esophageal pH monitoring documented incomplete acid suppression in this group of infants, children, adolescents and teens with EERD. Monitoring of gastric acid suppression can be useful in guiding the follow-up of EERD patients who receive acid suppressive therapy.
