Answer

Investigate the possible etiology of a patient's bronchiectasis. Specifically, allergic bronchopulmonary aspergillosis, atypical mycobacterial infections, immunodeficiency states, and autoimmune diseases are causes of bronchiectasis that may be treated effectively once diagnosed.

Cystic fibrosis (CF), Young syndrome, primary ciliary dyskinesia, and alpha1-antitrypsin (AAT) deficiency require aggressive treatment, as well as genetic counseling for patients and their families. Likewise, congenital abnormalities should be identified as such for the patient and their family.

Foreign body obstruction needs to be excluded as an etiology in all patients.
