Insights
Persistent wheezing in infants may indicate primary tracheomalacia, not just cystic fibrosis-related lung disease. Early diagnosis via bronchoscopy avoids unnecessary treatments and investigations.
Area of Science:
- Pediatric Pulmonology
- Respiratory Medicine
- Medical Diagnostics
Background:
- Persistent infant wheezing can mimic or complicate cystic fibrosis-related lung disease.
- Poor response to bronchodilators warrants investigation into alternative etiologies.
Purpose of the Study:
- To identify primary tracheomalacia as a cause of persistent, bronchodilator-unresponsive wheezing in infants.
- To highlight the importance of early diagnosis to guide appropriate management.
Main Methods:
- Case series describing 3 infants with persistent wheezing.
- Diagnosis confirmed using flexible bronchoscopy during spontaneous respiration.
Main Results:
- All 3 infants were diagnosed with primary tracheomalacia.
- This condition presented as persistent wheezing unresponsive to bronchodilators.
Conclusions:
- Primary tracheomalacia should be considered in infants with persistent wheezing.
- Early recognition via bronchoscopy can prevent unnecessary investigations and corticosteroid use.
Abstract:
Persistent wheezing, poorly responsive to bronchodilator therapy, raises concerns about the progression of cystic fibrosis-related lung disease. We describe 3 infants with such symptoms who were observed to have primary tracheomalacia. The diagnoses were made using flexible bronchoscopy during spontaneous respiration. Early recognition of this etiology can limit unnecessary investigation and the overuse of empirical treatments such as oral and inhaled corticosteroids.

CF is primarily caused by a genetic mutation in a chromosome 7 gene coding for the cystic fibrosis transmembrane conductance regulator (CFTR) protein. The most common gene mutation leading to CF is the ΔF508 mutation, but...
