Diagnosis and treatment of bronchiectasis, clinical review

Bronchiectasis is a common disease in clinical practice and has non-specific airway symptoms. Non-cystic fibrosis bronchiectasis is usually caused by airway infection, but other etiology should be ruled out. Because stasis of secretions in airway will lead to chronic colonization of bacteria, enhancing airway clearance is important to therapy. Besides, antibiotics therapy for bacteria colonization is also important. This clinical review focuses on various etiologies, diagnostic testing, microbiology, and management of patients with non-cystic fibrosis bronchiectasis.
