Laryngeal manifestations of gastroesophageal reflux disease (GERD) in pediatric patients: The usefulness of therapeutic (proton pump inhibitor (PPI)) trials

Abstract

Gastroesophageal reflux, common in infants, usually resolves spontaneously by 12 to 18 months. Gastroesophageal reflux disease (GERD) contributes to certain respiratory symptoms, but is reported to be due to other causal diseases, such as tracheolaryngeal anomaly, congenital esophageal hiatal hernia, and cerebral palsy, in pediatric patients. We report 4 pediatric cases with unusual laryngeal disorders, especially posterior glottic lesion, induced by gastroesophageal reflux without other causal disease. Subject 1 was a 1-year-old boy showing severe laryngeal spasm, Subject 2 a 3-year-old boy with life-threatening supraglottic stenosis, Subject 3 a 5-year-old boy whose voice had reached near aphonia with multiple laryngeal granulomatous lesions, and Subject 4 an 8-year-old boy with persistent abnormal throat sensations. Their symptoms were recalcitrant to conventional therapy. Their case histories (much belching and hiccups) and findings for the posterior glottitis, etc., suggested that symptoms might be induced by GERD, but, barium esophagography and esophagoscopy provided no conclusive proof. We could not monitor their ph because of the excessive physical and psychological stress involved. After therapeutic trials with a proton pump inhibitor (lansoprazole 10-15 mg) for 8 weeks, all had recovered almost completely without side effects.
