Eosinophilic bronchitis, a cough associated with sputum eosinophilia, can be an occupational airway disease. Monitoring induced sputum is crucial for diagnosing this condition, which may mimic asthma.

Area of Science:

  • Occupational Medicine
  • Pulmonology
  • Allergy and Immunology

Background:

  • Eosinophilic bronchitis is a condition characterized by cough and sputum eosinophilia.
  • Unlike asthma, it typically lacks variable airflow obstruction and airway hyperresponsiveness.
  • Occupational exposures are increasingly recognized as potential triggers.

Purpose of the Study:

  • To highlight eosinophilic bronchitis as a distinct occupational airway disease.
  • To emphasize its diagnostic features and potential work-related causes.
  • To discuss its relationship with occupational asthma.

Main Methods:

  • Review of current literature on occupational eosinophilic bronchitis.
  • Analysis of diagnostic criteria, including sputum analysis and lung function tests.

  • Discussion of potential occupational allergens and sensitizers.

    • Main Results:

    • Eosinophilic bronchitis can develop due to occupational exposures to allergens like natural rubber latex and mushroom spores.
    • The condition presents with corticosteroid-responsive cough and sputum eosinophilia.
    • The progression of eosinophilic bronchitis to occupational asthma remains uncertain.

    Conclusions:

    • Eosinophilic bronchitis should be considered an occupational airway disease.
    • Induced sputum examination is recommended for objective monitoring.
    • Lung function monitoring during and after work exposure is advised for diagnosis.
