Is prednisolone (corticosteroid) used to treat Chronic Obstructive Pulmonary Disease (COPD) exacerbations, similar to its use in asthma?

Systemic Corticosteroids for COPD Exacerbations

Yes, prednisolone (or other systemic corticosteroids) should be given for COPD exacerbations, similar to asthma, using 30-40 mg of oral prednisone daily for 5 days. 1, 2

Standard Treatment Protocol

The oral route is strongly preferred over intravenous administration for COPD exacerbations, as it provides equivalent clinical outcomes with fewer adverse effects and lower healthcare costs. 1, 3 A large observational study of 80,000 non-ICU patients demonstrated that intravenous corticosteroids were associated with longer hospital stays and higher costs without clear evidence of benefit. 1, 2

Dosing Recommendations

• First-line therapy: Oral prednisolone 30-40 mg once daily for 5 days 1, 2, 4
• If oral route not possible: Intravenous hydrocortisone 100 mg (equivalent to oral prednisolone 30 mg) 3, 2
• Maximum duration: 5-7 days to minimize adverse effects while maintaining efficacy 1, 3

The 5-day course is as effective as 10-14 day courses for improving lung function and symptoms while minimizing adverse effects. 1, 2 No tapering is required for courses up to 2 weeks, and corticosteroids can be stopped abruptly from full dosage. 2

Clinical Benefits

Systemic corticosteroids in COPD exacerbations provide multiple benefits:

• Shorten recovery time and improve lung function (FEV1) 1, 2
• Improve oxygenation and reduce bronchial mucosa edema 1
• Reduce treatment failure rates with odds ratio of 0.01 compared to placebo 1, 2
• Prevent hospitalization for subsequent exacerbations in the first 30 days (hazard ratio 0.78) 1, 2
• Reduce risk of early relapse and shorten length of hospital stay 1

When to Use Corticosteroids in Community Settings

The British Thoracic Society guidelines specify that oral corticosteroids should be used in the community when: 5

• The patient is already on maintenance oral corticosteroids 5
• There is a previously documented response to oral corticosteroids 5
• Airflow obstruction fails to respond to increased bronchodilator dose 5
• This is the first presentation of airflow obstruction 5

However, more recent guidelines recommend systemic corticosteroids for all patients with COPD exacerbations severe enough to seek emergent medical care, as they reduce treatment failure by over 50%. 3

Blood Eosinophil-Guided Therapy

Patients with blood eosinophil count ≥2% show significantly better response to oral corticosteroids, with treatment failure rates of only 11% versus 66% with placebo. 1, 2 However, the American Thoracic Society/European Respiratory Society guidelines recommend treatment for all COPD exacerbations regardless of eosinophil levels. 1

A 2024 randomized controlled trial (STARR2) demonstrated that blood eosinophil-directed prednisolone therapy was non-inferior to standard care and can safely reduce systemic glucocorticoid use in clinical practice. 6 Similarly, the 2019 CORTICO-COP trial showed that eosinophil-guided therapy reduced the median duration of systemic corticosteroid therapy from 5 days to 2 days without compromising outcomes. 7

If blood eosinophil count is available and <2%, consider whether the patient truly needs corticosteroids, but do not withhold treatment in patients with severe exacerbations. 1, 2

Critical Pitfalls to Avoid

• Never extend treatment beyond 5-7 days, as longer courses increase adverse effects without additional benefit and are associated with increased rates of pneumonia-associated hospitalization and mortality. 1, 2
• Do not use intravenous corticosteroids routinely when the patient can tolerate oral medications. 1, 3
• Never use systemic corticosteroids for chronic maintenance therapy to prevent exacerbations beyond the first 30 days, as no evidence supports this and risks outweigh benefits. 1, 2
• Do not continue corticosteroids long-term after an acute exacerbation unless specifically indicated. 5, 3

Adverse Effects to Monitor

Short-term corticosteroid use is associated with: 1, 2

• Hyperglycemia (odds ratio 2.79) - particularly important in diabetic patients 1, 2
• Weight gain and fluid retention 1, 2
• Insomnia and mood changes 1, 2

A 2007 randomized controlled trial comparing oral versus IV prednisolone found no differences in treatment failure, length of hospital stay, or clinical outcomes, confirming that oral administration is equally effective. 8

Post-Treatment Maintenance

After completing oral prednisolone for the acute exacerbation, initiate or optimize maintenance therapy with inhaled corticosteroid/long-acting β-agonist combination or inhaled long-acting anticholinergic monotherapy to prevent future exacerbations. 1, 3 This maintains the improved lung function achieved during acute treatment and reduces relapse risk. 2
