Follicular tracheitis (also known as tracheal cobblestoning) is an entity that is poorly described and of unclear significance. The objective of this study was to better define follicular tracheitis and determine the association between the clinical finding of follicular tracheitis on bronchoscopy and objective evidence of gastroesophageal reflux disease.

Methods

Retrospective chart review of children with recurrent croup having undergone a rigid bronchoscopy and an investigation for gastroesophageal reflux between 2001 and 2013.

Results

117 children with recurrent croup children age 6–144 months were included in the study. Follicular tracheitis was noted on 41% of all bronchoscopies. Fifty-nine percent of all children who underwent bronchoscopy were diagnosed with gastroesophageal reflux on at least one investigation. Forty-nine of 117 children underwent a pH probe study, and 51% were found to have evidence of reflux on this study. Nine children were diagnosed with eosinophilic esophagitis. Three patients underwent a biopsy of the follicular tracheitis lesions, which revealed chronic inflammation. There was no evidence of an association between findings of follicular tracheitis and a positive test for gastroesophageal reflux (p = 0.52) or a positive pH probe study (p = 0.64). There was no association between follicular tracheitis and subglottic stenosis (p = 0.33) or an history of asthma and/or atopy (p = 0.19).

Conclusion

In children with recurrent croup, follicular tracheitis remains an unspecific finding associated with an inflammatory disorder of unknown etiology.
