Management of COPD Exacerbations with Corticosteroids
A short course (5-7 days) of systemic corticosteroids should be given to all COPD patients experiencing an exacerbation, alongside tiotropium and salbutamol, regardless of fever status, but with careful monitoring in diabetic patients. 1
Corticosteroid Therapy Recommendations
Duration and Dosing
- Use a 5-day course of systemic glucocorticoids for COPD exacerbations, as this is as effective as longer courses (14 days) 1, 2
- Recommended dosing: 40mg prednisone daily for 5 days 1, 2
- Limit total exposure to ≤200mg prednisone equivalents for the entire exacerbation course 1
Benefits of Short-Course Steroids
- Short-course steroids (5 days) have been shown to be non-inferior to conventional longer courses (14 days) in preventing reexacerbations within 6 months 2
- Short courses significantly reduce cumulative steroid exposure (379mg vs 793mg) without compromising efficacy 2
- Cochrane review confirms that 5-day courses are likely sufficient for treating COPD exacerbations 3
Clinical Outcomes
- Systemic corticosteroids improve airflow, decrease treatment failure rates, and reduce risk of relapse 4
- They can prevent hospitalization for subsequent exacerbations in the first 30 days following the initial exacerbation 5
- No evidence supports using systemic corticosteroids beyond the first 30 days to prevent future exacerbations 5
Bronchodilator Therapy
Combine corticosteroids with short-acting bronchodilators:
Tiotropium has been used concomitantly with short-acting bronchodilators and steroids without increased adverse reactions 6
Special Considerations for Diabetic Patients
- Monitor blood glucose levels closely in diabetic patients, as systemic corticosteroids can cause hyperglycemia 1
- Short-course therapy (5 days) minimizes the risk of significant hyperglycemia compared to longer courses 2
- The benefits of treating the exacerbation with systemic corticosteroids generally outweigh the risks of short-term hyperglycemia 5
Potential Adverse Effects
- Short-term adverse effects include hyperglycemia, weight gain, and insomnia 5
- Long-term risks (which are minimized with short courses) include:
- Osteoporosis
- Increased infection risk
- Muscle weakness
- Adrenal suppression
- Skin thinning and bruising 1
Follow-up and Monitoring
- Schedule follow-up within 1-2 weeks to assess response to treatment 1
- Consider chest radiograph if symptoms persist 1
- Review medication technique and provide education on exacerbation prevention 1
- Monitor for decline in FEV1 >50 mL/year, which may indicate need for more aggressive therapy 1
Common Pitfalls to Avoid
- Avoid unnecessarily long courses of steroids (>7 days), as they increase adverse effects without additional clinical benefit 3, 2
- Don't withhold steroids in COPD exacerbations, as they are a standard of care for patients with exacerbations severe enough to seek medical care 4
- Tapering of short-course systemic corticosteroids is generally unnecessary, as the risk for HPA-axis suppression is negligible with short courses 7
- Don't continue systemic corticosteroids beyond the acute exacerbation period, as long-term use has no evidence of benefit for preventing future exacerbations 5
