Treatment of Bronchiectasis
The treatment of bronchiectasis should target four key components: chronic bronchial infection, inflammation, impaired mucociliary clearance, and structural lung damage. 1
Airway Clearance Techniques
- All patients with chronic productive cough or difficulty expectorating sputum should be taught airway clearance techniques by a trained respiratory physiotherapist, with sessions lasting 10-30 minutes, once or twice daily 1, 2
- Techniques may include active cycle of breathing, postural drainage, manual techniques, or mechanical devices 2
- Consider intermittent positive pressure breathing or non-invasive ventilation during acute exacerbations to reduce work of breathing 1
Mucoactive Treatments
- Consider long-term mucoactive treatment for patients with difficulty expectorating sputum, poor quality of life, or failure of standard airway clearance techniques 1
- Consider humidification with sterile water or normal saline to facilitate airway clearance 1, 2
- Do not routinely use recombinant human DNase (dornase alfa) in adults with non-CF bronchiectasis 1, 2
Pulmonary Rehabilitation
- Patients with impaired exercise capacity should participate in pulmonary rehabilitation programs and take regular exercise 3, 2
- Pulmonary rehabilitation can improve exercise capacity, reduce cough symptoms, and enhance quality of life 2
- Regular exercise should be maintained after formal rehabilitation 2
Antibiotic Therapy for Exacerbations
- Treat exacerbations with 14 days of antibiotics, with selection based on previous sputum culture results 3, 2
- Obtain sputum cultures before starting antibiotics whenever possible 1, 2
- Common pathogens and recommended antibiotics include:
- Consider intravenous antibiotics for patients who are particularly unwell, have resistant organisms, or have failed to respond to oral therapy (especially with P. aeruginosa) 3
Long-term Antibiotic Therapy
- Consider long-term antibiotics for patients with ≥3 exacerbations per year 1, 2
- First-line treatments include:
- P. aeruginosa infection is associated with a three-fold increase in mortality risk, almost seven-fold increase in risk of hospital admission, and an average of one additional exacerbation per patient per year 3, 1
Anti-inflammatory Treatments
- Do not routinely offer inhaled corticosteroids unless comorbid asthma or COPD is present 1, 2
- Do not offer long-term oral corticosteroids without other indications, such as ABPA, chronic asthma, COPD, or inflammatory bowel disease 1
- For patients with allergic bronchopulmonary aspergillosis (ABPA):
Bronchodilators
- Consider bronchodilators in patients with significant breathlessness, with appropriate inhalation device selection and inhaler technique training 1
- If treatment with bronchodilators does not result in a reduction in symptoms, it should be discontinued 1
Immunizations
- Offer annual influenza immunization to all patients with bronchiectasis 1
- Offer pneumococcal vaccination to all patients with bronchiectasis 1
- Consider influenza vaccination in household contacts of patients with immune deficiency and bronchiectasis 1
Monitoring and Follow-up
- Regular monitoring of sputum pathogens before and after implementation of long-term antibiotics 2
- Monitor for drug toxicity, especially with macrolides and inhaled aminoglycosides 2
- Annual assessment by respiratory physiotherapist to optimize airway clearance regimen 2
Surgical Options
- Surgery is not recommended for adult patients with bronchiectasis except in cases of localized disease and high exacerbation frequency despite optimization of all other aspects of bronchiectasis management 1
- Video-assisted thoracoscopic surgery (VATS) is often preferred to better preserve lung function and reduce scarring compared to open surgery 1
- Consider lung transplant referral in bronchiectasis patients aged 65 years or less if the FEV1 is <30% with significant clinical instability or if there is rapid progressive respiratory deterioration despite optimal medical management 1
Pitfalls and Caveats
- Do not extrapolate treatments from cystic fibrosis bronchiectasis, as treatment responses are different 3
- Avoid recombinant human DNase (dornase alfa) as it may worsen outcomes in non-CF bronchiectasis 1, 2
- Emergency surgery in unstable patients with massive hemoptysis is associated with higher morbidity and mortality reaching 37% 1
- P. aeruginosa infection requires aggressive management due to its association with worse outcomes 3, 1
