Bronchiectasis: the 'other' obstructive lung disease.

Bronchiectasis belongs to the family of chronic obstructive lung diseases, even though it is much less common than asthma, chronic bronchitis, or emphysema. Clinical features of these entities overlap significantly. The triad of chronic cough, sputum production, and hemoptysis always should bring bronchiectasis to mind as a possible cause. Chronic airway inflammation leads to bronchial dilation and destruction, resulting in recurrent sputum overproduction and pneumonitis. Once the diagnosis is confirmed, any potential predisposing conditions should be aggressively sought. The relapsing nature of bronchiectasis can be controlled with antibiotics, chest physiotherapy, inhaled bronchodilators, proper hydration, and good nutrition. In rare circumstances, surgical resection or bilateral lung transplantation may be the only option available for improving quality of life. Prognosis is generally good but varies with the underlying syndrome.
