If chronic cough persists despite following these measures, nonasthmatic eosinophilic bronchitis
should be considered.
The report contains new sections on topics such as nonasthmatic eosinophilic bronchitis
, acute bronchitis, nonbronchiectatic suppurative airway diseases, environmental occupational causes of cough, tuberculosis and other infections, uncommon causes of cough, unexplained cough, and potential future therapies.
Eosinophilic bronchitis can be diagnosed by documenting sputum eosinophiia.
Both groups improved with inhaled corticosteroids, indicating treatment of eosinophilic bronchitis is worthwhile.
Eosinophilic bronchitis is often benign and self-limiting, but one reason for recognizing and treating the disorder is its possible role as a precursor to asthma or chronic obstructive pulmonary disease.
