Bronchiectasis Flashcards
Epidemiology of bronchiectasis ?
Females
most diagnoses over 70
Pathophys of bronchiectasis ?
occurs after airway damage
damage = persistent bacterial colonisation = chronic inflammation
permanent dilation of bronchi and mucus plugging = reduced bacterial clearance
What is yellow nail syndrome?
Yellow finger nails
bronchiectasis
lymphedema
What could cause damage to airway that could cause bronchiectasis?
Idiopathic (no apparent cause)
Pneumonia
Whooping cough (pertussis)
Tuberculosis
Alpha-1-antitrypsin deficiency
Connective tissue disorders (e.g., rheumatoid arthritis)
Cystic fibrosis
Yellow nail syndrome
Presentation of bronchiectasis?
Productive and persistent cough (mucus)
Dyspnoea
chest pain
haemoptysis
recurrent chest infections
weight loss
Signs of bronchiectasis on examination?
Sputum pot by the bedside
Oxygen therapy (if needed)
Weight loss (cachexia)
Finger clubbing
Signs of cor pulmonale (e.g., raised JVP and peripheral oedema)
Scattered crackles throughout the chest that change or clear with coughing
Scattered wheezes and squeaks
Investigation of bronchiectasis?
aim to find underlying cause
Sputum culture
CXR
HRCT
What common organisms found in sputum for bronchiectasis?
Haemophilus influenza
Pseudomonas aeruginosa
What is often found on CXR for bronchiectasis?
Tram-track opacities (parallel markings of a side-view of the dilated airway)
Ring shadows (dilated airways seen end-on)
Management of bronchiectasis?
Vaccines (e.g., pneumococcal and influenza)
Respiratory physiotherapy to help clear sputum
Pulmonary rehabilitation
Long-term antibiotics (e.g., azithromycin) for frequent exacerbations (e.g., 3 or more per year)
Inhaled colistin for Pseudomonas aeruginosa colonisation
Long-acting bronchodilators may be considered for breathlessness
Long-term oxygen therapy in patients with reduced oxygen saturation
Surgical lung resection may be considered for specific areas of disease
Lung transplant is an option for end-stage disease
Management for infective exacaerbations?
Sputum culture (before abx)
Extended courses of antibiotics, usually 7–14 days
Ciprofloxacin is the usual choice for exacerbations caused by Pseudomonas aeruginosa
What abx to use for infective exaccerbation of bronchiectasis of Pseudomonas aeruginosa
ciprofloxacin
