Overview

Bronchiectasis is normally diagnosed after months or years of symptoms. Patients have respiratory complications, infection, and hemoptysis. Death can be caused by cardiac and respiratory failure. Bronchiectasis shows a higher mortality with males, advanced age, poor functional status, severe disease based on radiographic findings, and evidence of hypoxemia and hypercapnia.

Natural History

  • There is often a delay between the onset of symptoms and diagnosis
  • The classic symptoms are cough, daily mucopurulent sputum production, and dyspnea
    • These symptoms are usually present for months to years
    • The symptoms are manifestations of the lung being repeatedly damaged due to any number of causes

Complications

Prognosis

  • Infected with Pseudomonas aeruginosa, severe exacerbations, and systemic inflammation are associated with disease advancement
  • Up to 10% of adults die within 5-8 years of diagnosis (majority being respiratory related)[6]
