Clinical Brief: Etiologic Evaluation and First-Line Treatment of Bronchiectasis

Main Discussion Topics

• Etiologic evaluation is important, though many cases remain idiopathic.
• Treatment follows both “one-size-fits-all” baseline approaches and targeted interventions based on identified causes.
• First-line treatments focus on airway clearance, hydration, and infection management.

Key Points for Physicians

• Universal approaches include:
  • Airway clearance techniques
  • Physical exercise/pulmonary rehabilitation
  • Regular clinical follow-up
  • Nutritional counseling
  • Vaccinations
• Etiologic evaluation may identify treatable traits:
  • CFTR mutations (potential for modulators)
  • Low IgG (consider supplementation)
  • Aspiration/reflux (specific management)
  • Sinus disease (targeted treatment)
• Personalize approaches based on the patient’s specific presentation and underlying etiology.

Notable Insights

In approximately 40% to 50% of cases, etiologic evaluation can identify host susceptibility factors that allow for targeted interventions beyond general management.

Clinical Significance

Combining universal bronchiectasis management approaches with etiology-specific interventions creates a more effective personalized treatment strategy.
