Management of COPD Exacerbation with Fever and Purulent Sputum
This patient requires both oral corticosteroids and antibiotic therapy, with amoxicillin or tetracycline as first-line antibiotic choices. 1, 2
Antibiotic Selection
Amoxicillin or tetracycline are the recommended first-line antibiotics for this patient. 3, 1 The presence of three cardinal symptoms—increased dyspnea (evidenced by requiring albuterol 5 times daily), increased sputum volume (3 weeks of productive cough), and purulent sputum with fever/chills—clearly indicates bacterial infection requiring antibiotic therapy. 3, 2
First-Line Options:
- Amoxicillin (preferred unless previously used with poor response) 3, 1
- Tetracycline derivatives (alternative first-line choice) 3
- Duration: 5-7 days 1, 2
Second-Line Options (if first-line fails):
The most common pathogens in COPD exacerbations are Streptococcus pneumoniae, Haemophilus influenzae, and Moraxella catarrhalis. 3 Common, inexpensive antibiotics are usually adequate; newest brands are rarely appropriate. 3
Oral Corticosteroid Indication
Yes, this patient should receive oral corticosteroids. 3, 1, 2 Despite being on Trelegy (which contains an inhaled corticosteroid), the patient demonstrates airflow obstruction that has failed to respond adequately to increased bronchodilator use (requiring albuterol 5 times daily). 3
Dosing:
- Prednisolone 30-40 mg orally daily for 5 days 1, 2
- Alternatively, 100 mg hydrocortisone IV if oral route not possible 3, 1
- Do not continue beyond 5-7 days 1, 2
The 2017 ERS/ATS guidelines provide a conditional recommendation for oral corticosteroids in outpatients with COPD exacerbations, as they improve lung function, oxygenation, and shorten recovery time. 3, 1 Oral administration is equally effective as intravenous therapy. 4, 1
Bronchodilator Optimization
Continue and optimize short-acting bronchodilator therapy. 1, 2 The patient is already using albuterol frequently (5 times daily), indicating severe bronchospasm.
- Nebulized salbutamol 2.5-5 mg every 4-6 hours (or more frequently if needed) 3, 1
- Consider adding ipratropium bromide 0.25-0.5 mg for severe exacerbations or poor response to beta-agonist alone 3, 1, 2
- Nebulizers should be driven by compressed air (not oxygen) if hypercapnia is present 3
Critical Assessment Points
Immediate Evaluation Needed:
- Arterial blood gas analysis to assess for respiratory failure (pH <7.26 predicts poor prognosis) 1, 2
- Chest radiograph to exclude pneumonia, pneumothorax, or other complications 1
- Oxygen saturation monitoring (target 88-92% in COPD patients) 2
Red Flags Requiring Hospitalization:
- Use of accessory respiratory muscles 2
- Inability to speak in full sentences 2
- Cyanosis or hemodynamic instability 2
- pH <7.26 or persistent hypoxemia despite oxygen 1, 2
- Failure to respond to initial outpatient management 3
Common Pitfalls to Avoid
Do not use oxygen >28% FiO2 or >2 L/min via nasal cannula until arterial blood gases are known in elderly COPD patients, as this can precipitate respiratory acidosis. 1, 2 The fever and chills in this patient raise concern for possible pneumonia, which would require chest radiography to differentiate from simple COPD exacerbation. 3
Do not continue oral corticosteroids beyond 5-7 days unless specifically indicated, as maintenance therapy is associated with worse mortality and skeletal muscle myopathy. 5, 1 The patient is already on inhaled corticosteroids via Trelegy, which should be continued. 6, 7
Ensure sputum culture is obtained if purulent sputum is present, particularly if the patient fails to respond to first-line antibiotics. 1 This helps guide second-line therapy if needed, especially given increasing resistance patterns. 3
