Three-Part Question:
In [children with gastroesophageal reflux] does [treatment with a proton pump inhibitor] [decrease symptoms, increase gastric pH, and improve endoscopic findings]?
Clinical Scenario:
An 18-month-old boy with cerebral palsy is brought to your office because of "spitting up" after feeds. It has been a problem for the past several months but is progressively worsening and now occurs after every meal and even at night. He was breast fed for 12 months and has slight developmental delay. Height and head circumference are between 25-50th percentile, but weight is below 5th percentile for age. A barium swallow reveals significant gastro-oesophageal reflux to the pharynx. A gastroscopic examination with biopsy reveals moderate esophagitis without eosinophilia. You wonder if a proton pump inhibitor will be an effective treatment.

Author Commentary:
There is adequate and consistent evidence that the proton pump inhibitor omeprazole is effective in the treatment of gastroesophageal reflux in children. In the five studies that addressed clinical outcomes, all patients had improvement in their symptoms. All of the studies addressed endoscopic outcomes and all patients had improvement in their findings after treatment. Six of the seven studies included patients who had failed other treatment modalities. Four of the five studies which looked at oesophageal pH showed an increase with treatment, which is indicative of decreased acid production. In the three studies that included children with significant comordities such as oesophageal atresia, neurological impairment and cystic fibrosis, omeprazole was effective. In the four studies that had long-term follow-up the relapse rates ranged from 17% to 60%. This higher relapse rates in the studies by Kato et al and DeGiacomo et al could be attributed to the fact that there were more patients with comorbid conditions and untreated H pylori infections, respectively. Based on these results, clinicians may want to consider Hassall et al's advice that "the high degree of efficacy and safety of omeprazole defines a new standard for "optimized medical management" in children. It is our opinion that in most circumstances, a trial of the new optimized medical therapy should be considered before antireflux surgery."
Bottom Line:
When children with gastroesophageal reflux fail first line therapy, omeprazole is an effective second-line choice. It may also be effective treatment in children with comorbid conditions such as cystic fibrosis, repaired esophageal atresia, and neurological impairment.
Level of Evidence:
Level 2: Studies considered were neither 1 or 3
