Peribronchial Inflammation: Causes, Symptoms & Treatment
Peribronchial inflammation (also peribronchitis) refers to inflammation of the connective tissue and mucosa surrounding the bronchi (medium-sized airways). It is a descriptive term, not a specific disease.
Causes
- Respiratory infections (bronchitis, pneumonia)
- Allergic reactions (pollen, dust mites, pet dander)
- Environmental irritants (smoke, pollutants, chemicals)
- Autoimmune disorders (asthma, sarcoidosis)
- Chronic respiratory diseases (COPD, bronchiectasis)
Symptoms
- Persistent cough (dry or productive)
- Wheezing (especially on exhalation)
- Shortness of breath on exertion
- Chest tightness or discomfort
- Increased mucus production
Diagnosis
Clinical history, physical exam (auscultation), imaging (CXR, CT), and pulmonary function tests.
Treatment
Target the underlying cause: bronchodilators, inhaled corticosteroids, antibiotics (if infection), allergen avoidance, and in severe cases, supplemental oxygen.
