Proximal oesophageal pH-metry in children with respiratory symptoms
Insights
Gastro-oesophageal reflux in children does not explain respiratory symptoms. Twenty-four-hour pH monitoring showed no significant differences in proximal acid exposure between children with and without respiratory issues.
Area of Science:
- Pediatric Gastroenterology
- Respiratory Medicine
- Diagnostic Technology
Background:
- Gastro-oesophageal reflux (GER) is common in infants and can present with diverse symptoms.
- The association between GER and respiratory symptoms in children remains a subject of investigation.
- Accurate diagnostic methods are crucial for understanding the pathophysiology of GER-related symptoms.
Purpose of the Study:
- To investigate the relationship between gastro-oesophageal reflux patterns and respiratory symptoms in pediatric patients.
- To determine if specific reflux parameters measured by dual-site 24-hour oesophageal pH recording correlate with respiratory symptoms.
Main Methods:
- Dual-site 24-hour oesophageal pH monitoring was performed on two groups of children: one with vomiting and/or respiratory symptoms (n=26, mean age 16.3 months) and another with vomiting and/or regurgitation (n=28, mean age 10.5 months).
- Analysis focused on comparing distal and proximal oesophageal acid exposure and other pH-metry variables between groups.
Main Results:
- Thirty-nine children were diagnosed with gastro-oesophageal reflux.
- In all children with GER, distal oesophageal acid exposure was significantly longer than proximal exposure (p < 0.01).
- Proximal pH electrode data showed no significant differences between children with and without respiratory symptoms for any studied variable.
Conclusions:
- The study found no specific gastro-oesophageal reflux pattern, identified via 24-hour pH-metry, that accounts for respiratory symptoms in children with documented GER.
- These findings suggest that respiratory symptoms in children with GER may not be solely explained by the reflux pattern itself.
Abstract:
Twenty-six children (mean age: 16.3 months) with vomiting and/or respiratory symptoms and 28 children (mean age 10.5 months) with vomiting and/or regurgitation underwent dual-site 24-hour oesophageal pH recording. Thirty-nine children had gastro-oesophageal reflux and in all of them, irrespective of respiratory symptoms, distal oesophageal acid exposure was significantly (p < 0.01) longer than proximal exposure. Furthermore, data from the proximal pH electrode were not significantly different between children with and without respiratory symptoms for any of the variables studied. In conclusion, no single features of reflux pattern, as determined by 24-hours pH-metry, account for respiratory symptoms in children with documented gastro-oesophageal reflux.
