A 64-year-old smoker with COPD presents with increased sputum volume, purulence, and breathlessness. Along with bronchodilators and systemic steroids, what antibiotic strategy is recommended?
Answer and explanation
Correct answer: C. Empiric targeted antibiotic therapy
- Step 1: Anthonisen criteria classify acute COPD exacerbations by increased dyspnea, increased sputum volume, and increased sputum purulence.
- Step 2: When sputum purulence is present with other cardinal symptoms, empiric antibiotic therapy targeting common pathogens like Haemophilus influenzae and Streptococcus pneumoniae significantly reduces clinical failure.
Answer
Empiric targeted antibiotic therapy.
Why not the others: Withholding antibiotics in severe exacerbations with purulent sputum is associated with increased treatment failure and mortality. Nebulized colistin is reserved for cystic fibrosis or multidrug-resistant gram-negative bronchiectasis. Voriconazole is indicated for invasive aspergillosis, not typical bacterial COPD exacerbations.
