Study Notes

Bronchiectasis

  • Bronchiectasis is a chronic, obstructive, suppurative airway disease
  • Characterized by abnormal and irreversible enlargement of the airways
  • Airways are damaged due to destruction of the airway architecture
  • Bronchi and bronchioles normally narrow as they go deeper
  • In bronchiectasis, they maintain the same caliber or dilate as they go distally.

Objectives

  • Define bronchiectasis
  • Detail causes of bronchiectasis
  • Identify clinical features of bronchiectasis
  • Diagnose bronchiectasis
  • Treat bronchiectasis

Causes

  • Infection-Related:
    • Tuberculosis (most common)
    • Nontuberculous mycobacteria
    • Pneumonia (especially recurrent)
    • Whooping cough
    • Measles
  • Airway Obstruction:
    • Tumor
    • Enlarged hilar lymph nodes
    • Foreign body
  • Immunodeficiency:
    • Common variable immunodeficiency
    • Primary hypogammaglobulinaemia
    • HIV
  • Hypersensitivity:
    • Allergic bronchopulmonary aspergillosis
  • Autoimmune Disorders:
    • Rheumatoid arthritis
    • Sjogren's syndrome
    • Inflammatory bowel disease
  • Mucociliary Dysfunction:
    • Cystic fibrosis
    • Primary ciliary dyskinesia
    • Kartagener syndrome
    • Primary hypogammaglobulinaemia

Clinical Picture

  • Symptoms:
    • Chronic, daily, persistent cough
    • Copious (over 100 ml/day) and continuously purulent sputum
    • Pleuritic pain (when infection involves the pleura or with segmental collapse due to retained secretions)
    • Dyspnea
  • Other Symptoms:
    • Haemoptysis (streaks or larger volumes, sometimes requiring bronchial artery embolisation)
    • Infective exacerbation (increased sputum, fever, malaise, anorexia)
    • Halitosis (bad breath, commonly with purulent sputum)
    • General debility (difficulty maintaining weight, anorexia, exertional breathlessness)

Signs

  • Clubbing of fingers
  • Coarse inspiratory and expiratory crepitation (changes after coughing, caused by air passing through mucus-filled bronchi)
  • Wheezing (in advanced cases, caused by scarring and overlying bronchial breathing)

Investigations

  • CXR: May show mild bronchiectasis (not always apparent), ring shadows/tramlines (thick airways), or honey-comb appearance (late).

  • Bronchoscopy: Detect site of haemoptysis and underlying cause

  • PFT (pulmonary function test): Obstructive pattern with incomplete reversibility (similar to COPD)

  • High-resolution chest CT scan: Used to diagnose bronchiectasis.

    • Diagnostic criteria include airway diameter greater than accompanying vessel, lack of distal airway tapering, and presence of bronchial wall thickening or cysts

  • Sputum culture: Reveals organisms such as Pseudomonas aeruginosa, Staphylococcus aureus, fungi (aspergillus), and non-tuberculous mycobacteria

  • Sputum microbiology: Including atypical organisms (acid-fast bacilli and Aspergillus)

  • Immunoglobulin levels: Checked if ciliary dysfunction is suspected

  • Nasal FeNO sampling: Screening test for ciliary dysfunction, followed by nasal brush biopsy (if FeNO abnormal) and genetic testing

  • Connective tissue disease and immune function evaluation: Including immunoglobulin levels

  • Even with advanced evaluation, more than half of bronchiectasis cases are idiopathic (unknown cause).

Treatment

  • Treatment focuses on clearing the airway, treating infections, and preventing exacerbations
  • Physiotherapy (postural drainage): 5-10 minutes, once or twice daily, to empty secretions
  • Bronchodilators: For obstruction
  • Antibiotics: For infections (Haemophilus influenzae, Pseudomonas aeruginosa, Klebsiella spp., Streptococcus pneumoniae are common)
  • Mucolytics: For thick sputum
  • Surgery: Considered if unilateral and confined to a lobe.
  • Vaccines: Influenza and pneumococcal vaccines; smoking cessation advised
  • Treatment of underlying cause: May not improve current symptoms, but might prevent future progression

Complications

  • Respiratory failure
  • Recurrent infection
  • Pulmonary hypertension (cor pulmonale)
  • Pneumothorax
  • Brain abscess
  • Amyloidosis (AA type, resulting in nephrotic syndrome)
