Abstract

Objective:

This study aimed to investigate pepsin as a marker of extra-oesophageal reflux disease by examining its presence in tracheal aspirates and correlating it with macroscopic changes on laryngobronchoscopy, along with the results of standard tests for gastro-oesophageal reflux disease and clinical features.

Methods:

A retrospective review was undertaken of a cohort of 188 paediatric patients who underwent laryngobronchoscopy at a tertiary children's hospital and for whom pepsin assay results of tracheal aspirates were available. An association analysis was performed.

Results:

The mean patient age was 3.99 (3.40–4.58) years, with a male preponderance (55 per cent). Positive changes on laryngobronchoscopy were significantly associated with positive tracheal pepsin findings (p < 0.0001) but not with positive standard gastro-oesophageal reflux disease investigations. A positive pepsin assay was significantly associated with a history of recurrent croup (p = 0.0385) and a diagnosis of cystic fibrosis (p = 0.0232).

Conclusion:

Macroscopic changes on laryngobronchoscopy were significantly associated with positive tracheal pepsin findings in this paediatric population, suggesting that extra-oesophageal reflux disease may be a contributing aetiology.
