Eosinophilic bronchitis
Eosinophilic bronchitis (pronunciation: ee-oh-sin-oh-fil-ik bron-kai-tis) is a type of chronic bronchitis characterized by an increased number of eosinophils, a type of white blood cell, in the lining of the bronchial tubes.
Etymology
The term "eosinophilic bronchitis" is derived from the Greek words "eos" meaning "dawn" and "philos" meaning "loving", referring to the eosinophil's affinity for eosin, a red dye used in staining cells for microscopic examination. "Bronchitis" comes from the Greek "bronkhos" meaning "windpipe" and "-itis" denoting inflammation.
Symptoms
The main symptoms of eosinophilic bronchitis include cough, shortness of breath, and wheezing. Unlike asthma, which it can resemble, eosinophilic bronchitis does not cause the airways to narrow (bronchoconstriction) or react to triggers (hyperresponsiveness).
Diagnosis
Diagnosis of eosinophilic bronchitis is typically made through a combination of patient history, physical examination, and laboratory tests. A key diagnostic feature is the presence of eosinophils in sputum, which can be detected through sputum induction.
Treatment
Treatment for eosinophilic bronchitis typically involves the use of corticosteroids, either inhaled or systemic, to reduce inflammation and control symptoms. Other treatments may include bronchodilators to relieve symptoms and leukotriene modifiers to reduce eosinophil activity.
