Treatment of Inflammatory Pericarditis

For acute inflammatory pericarditis, start combination therapy with aspirin or NSAIDs PLUS colchicine as first-line treatment, with gastroprotection, and reserve corticosteroids only for contraindications or treatment failure. 1

First-Line Therapy (Class I, Level A Recommendation)

The 2015 ESC Guidelines establish a clear treatment hierarchy:

Dual Anti-Inflammatory Regimen

NSAIDs or Aspirin (choose one):

  • Aspirin: 750-1000 mg every 8 hours 1
  • Ibuprofen: 600 mg every 8 hours 1
  • Duration: 1-2 weeks for uncomplicated cases, guided by symptoms and CRP normalization
  • Taper by 250-500 mg (aspirin) or 200-400 mg (ibuprofen) every 1-2 weeks 1
  • Always provide gastroprotection 1

PLUS Colchicine (mandatory adjunct):

  • Weight-adjusted dosing: 0.5 mg once daily if <70 kg OR 0.5 mg twice daily if ≥70 kg 1
  • Duration: 3 months 1
  • Tapering not mandatory, but can use 0.5 mg every other day in final weeks 1

This combination is superior to NSAIDs alone because colchicine halves the recurrence rate from 15-30% to approximately 7-15% 1.

Why This Matters for Outcomes

The evidence strongly supports avoiding corticosteroids as first-line therapy because they:

  • Promote chronic disease evolution 1
  • Increase recurrence rates (up to 50% after first recurrence if corticosteroids used) 1
  • Create drug dependence 1

Second-Line Therapy: When to Use Corticosteroids

Only consider low-dose corticosteroids when: 1

  • Contraindication to aspirin/NSAIDs (true allergy, recent GI bleeding, high bleeding risk on anticoagulation)
  • Treatment failure after adequate trial of NSAIDs + colchicine
  • Specific indications: autoimmune disease, post-pericardiotomy syndrome, pregnancy
  • Infectious cause has been excluded (especially bacterial and TB)

If corticosteroids are necessary:

  • Use low to moderate doses: prednisone 0.2-0.5 mg/kg/day (NOT 1.0 mg/kg/day) 1
  • Always combine with colchicine 1
  • Maintain initial dose until symptom resolution and CRP normalization
  • Taper extremely slowly—critical threshold is 10-15 mg/day prednisone where recurrences spike 1
  • At this threshold, decrease by only 1.0-2.5 mg every 2-6 weeks 1

Monitoring Treatment Response

Use CRP to guide therapy duration and assess response (Class IIa recommendation) 1:

  • Continue treatment until CRP normalizes
  • CRP elevation indicates inadequate treatment or recurrence
  • Don't taper medications while CRP remains elevated 1

Activity Restriction

Non-athletes: Restrict exercise until symptom resolution and normalization of CRP, ECG, and echocardiogram 1

Athletes: Minimum 3 months restriction from competitive sports after symptom onset, plus normalization of all parameters 1

Common Pitfalls to Avoid

  1. Starting corticosteroids first-line: This is explicitly NOT recommended (Class III) 1 and worsens long-term outcomes
  2. Using colchicine alone without NSAIDs: Colchicine is an adjunct, not monotherapy 1
  3. Inadequate treatment duration: Stopping NSAIDs before CRP normalizes leads to recurrence 1
  4. Rapid corticosteroid taper: If steroids are used, tapering too quickly (especially below 15 mg/day) triggers recurrences 1
  5. Omitting gastroprotection: NSAIDs at these doses require gastric protection 1

Recurrent or Refractory Cases

For patients who fail standard therapy, newer evidence supports IL-1 inhibitors (anakinra, rilonacept) for corticosteroid-dependent or colchicine-resistant recurrent pericarditis 2, 3, 4, though this represents escalation beyond initial inflammatory pericarditis management.
