Insights

Gastro-oesophageal reflux (GOR) is unlikely to cause irritability in infants younger than 3 months. Pathological GOR, defined by pH monitoring, was more common in older infants and always accompanied by vomiting.

Area of Science:

  • Pediatrics
  • Gastroenterology
  • Infant Health

Background:

  • Gastro-oesophageal reflux (GOR) is a potential cause of excessive crying and irritability in infants.
  • Identifying clinical predictors for pathological GOR is crucial for accurate diagnosis and management.

Purpose of the Study:

  • To evaluate the role of GOR in infant irritability.
  • To define clinical predictors of pathological GOR in infants.

Main Methods:

  • Retrospective review of 70 consecutively admitted infants with irritability and presumptive GOR.
  • Prolonged oesophageal pH monitoring was used to assess reflux.
  • Pathological GOR was defined as fractional reflux time >= 10%.

Main Results:

  • Pathological GOR was significantly less common in infants under 3 months (4.2%) compared to older infants (21.7%).
  • All infants with pathological GOR experienced frequent vomiting; 'silent' reflux was not observed.
  • Poor weight gain, feeding refusal, backarching, and sleep disturbance were not significantly associated with pathological GOR.

Conclusions:

  • Pathological GOR is an unlikely cause of irritability in infants under 3 months of age.
  • Clinical symptoms like vomiting are key indicators of pathological GOR, not subtle signs.
