Effects of maturation and gastric acidity on gastroesophageal reflux in infants
Insights
Prematurity and gastric acidity in infants significantly correlate with gastroesophageal reflux (GER). However, historical symptoms showed little relation to the measured amount of GER in this study.
Area of Science:
- Pediatrics
- Gastroenterology
- Neonatology
Background:
- Gastroesophageal reflux (GER) is common in infants.
- Accurate measurement of GER is crucial for diagnosis and management.
- Factors influencing GER severity require further investigation.
Purpose of the Study:
- To investigate the correlation between prematurity, postcibal gastric acidity, and historical symptoms with the amount of GER in infants.
- To utilize prolonged esophageal and intragastric pH monitoring for objective GER assessment.
Main Methods:
- Prospective study of 42 infants referred for GER over 16 months.
- Utilized prolonged intraesophageal pH monitoring for all infants.
- Performed intragastric pH monitoring in 18 infants after a formula meal.
Main Results:
- A significant positive correlation was found between prematurity and the amount of GER.
- Postcibal gastric acidity also showed a significant correlation with the observed GER.
- Historical symptoms had minimal correlation with GER measured by intraesophageal pH monitoring.
Conclusions:
- Prematurity and post-meal gastric acidity are key factors associated with GER severity in infants.
- Objective pH monitoring provides a more reliable assessment of GER than historical symptoms alone.
- Findings support the importance of considering infant's gestational age and gastric environment in GER evaluation.
Abstract:
Using prolonged esophageal pH monitoring, we examined 42 infants referred for gastroesophageal reflux (GER) over a 16-month interval. Eighteen of these infants were also examined with intragastric pH monitoring following a standard formula meal. We found that prematurity and postcibal gastric acidity were significantly correlated with the amount of GER observed. Historical symptoms appeared to have little correlation with the amount of GER as measured by prolonged intraesophageal pH monitoring.
