Eosinophilic bronchitis

Eosinophilic bronchitis is a type of chronic bronchitis characterized by an increased number of eosinophils, a type of white blood cell, in the lining of the airways of the lungs. This condition is not associated with asthma, although the symptoms are similar.

Symptoms

The main symptoms of eosinophilic bronchitis include:

• Cough
• Shortness of breath
• Wheezing
• Chest tightness

These symptoms are similar to those of asthma, but unlike asthma, eosinophilic bronchitis does not cause the airways to narrow (bronchospasm).

Causes

The exact cause of eosinophilic bronchitis is unknown. However, it is thought to be related to an abnormal immune response to inhaled substances, such as dust mites or pollen.

Diagnosis

Eosinophilic bronchitis is diagnosed based on the symptoms, a physical examination, and the results of tests, including:

• Spirometry
• Peak flow meter
• Bronchoscopy
• Sputum induction

Treatment

Treatment for eosinophilic bronchitis typically involves:

• Inhaled corticosteroids
• Leukotriene modifiers
• Long-acting beta agonists
