Healing of Erosive Esophagitis and Improvement of Symptoms of Gastroesophageal Reflux Disease After Esomeprazole Treatment in Children 12 to 36 Months Old.

Abstract

The aim of the study was to evaluate erosive esophagitis healing and symptom improvement with once-daily esomeprazole in children ages 12 to 36 months with endoscopically or histologically proven gastroesophageal reflux disease (GERD). Data from children ages 12 to 36 months were included in a post-hoc analysis of an 8-week, multicenter, randomized, and double-blind by dose strata study of patients ages 1 to 11 years with endoscopically or histologically confirmed GERD. Children were randomized to receive esomeprazole 5 or 10 mg once daily. Patients underwent endoscopy and, if required, mucosal biopsy at baseline. Patients who had erosive esophagitis (graded using the Los Angeles classification system) at baseline underwent a follow-up endoscopy at final study visit to assess healing of erosive esophagitis. Investigators scored severity of GERD symptoms at baseline and every 2 weeks using the Physician Global Assessment. Thirty-one of 109 primary study patients ages 12 to 36 months were included in the post hoc analysis. At baseline, 15 patients (48.4%) had erosive esophagitis, underwent follow-up endoscopy, and were healed after 8 weeks of esomeprazole treatment. Of the 19 patients with moderate-to-severe baseline Physician Global Assessment symptom scores, 84.2% had lower scores by the final visit. Following esomeprazole treatment, GERD symptoms were significantly improved from baseline to final visit (P ≤ 0.0018). Esomeprazole 5 or 10 mg may be used to successfully treat erosive esophagitis and symptoms of GERD in children as young as 1 year. Moreover, although not yet validated in pediatric patients, the Los Angeles classification system was useful in grading erosive esophagitis in children ages 12 to 36 months.
