NEJM: Pharmacologic Treatment of Reflux in Infants?

Posted on by

JR Barzilay et al. N Engl J Med 2024;391:960-962. Medication for Gastroesophageal Reflux Disease in Infants.

A recent case vignette of a 3 month old with reflux symptoms without response to dietary changes and positioning offers two potential management options. “Option 1” author advocates for use of a PPI (which I do NOT agree with):

“If conservative measures have been performed appropriately and a pediatric gastroenterology referral has been made, I would consider a short trial of medication, in accordance with guidelines from the North American and European Societies for Pediatric Gastroenterology, Hepatology, and Nutrition.2… in my experience, many pediatric gastroenterologists would conclude, on the basis of clinical symptoms, that the infant may have reflux esophagitis and would prescribe a trial of medication before considering invasive diagnostic procedures…There is no convincing evidence to support a difference between PPIs and histamine2-receptor antagonists in controlling symptoms of reflux.3 I recommend a 4-week trial of omeprazole with continuation of the nonpharmacologic treatments. If the medication is not effective, I would consider increasing the dose before terminating the trial. A PPI should not be discontinued abruptly if it has been used for several weeks, since rebound gastric hyperactivity may occur.”

“Option 2” author argues against use of medications:

“Gastric-acid inhibitors such as PPIs are often used in infants such as this one, even though there are no published studies supporting treatment.2 Several studies have indicated that PPIs and histamine2-receptor antagonists are ineffective for treating symptoms associated with infant reflux in the absence of endoscopically proven esophagitis.2….PPIs have been associated with bacterial overgrowth, respiratory infections, viral gastrointestinal illness, drug interactions, and adverse long-term bone health. The current recommendation from the North American and European Societies for Pediatric Gastroenterology, Hepatology, and Nutrition is to use PPIs (or histamine2-receptor antagonists if PPIs are contraindicated or unavailable) only in infants who have endoscopy-proven esophagitis.4“

My take:

  1. It is a mistake to publish this vignette reinforcing the idea that using a PPI in this setting is a good medical decision. Though use of a PPI is common in infants, it is rarely beneficial
  2. The vignette missed an opportunity to emphasize that some infants with reflux symptoms have oropharyngeal dysfunction, especially in those with brief resolved unexplained events (BRUEs)
  3. “Option 1” lists several fallacies —a. most pediatric GIs would NOT conclude that this infant would have reflux esophagitis –most reflux is non-erosive (especially in infants), b. even if PPIs were effective, there is not a strong argument for a 4 week trial in this age group. If PPIs were effective, response to treatment should be much quicker, and c. in this age group, a slow wean off PPIs is unnecessary. There is no proof that there is rebound gastric hyperactivity in infants.
