What is the recommended dose of glucocorticoids (e.g. prednisone) for a patient with a gout flare and impaired renal function (Chronic Kidney Disease, CKD stage 5)?

Glucocorticoid Dosing for Gout Flare in CKD Stage 5

For patients with gout flare and CKD stage 5, oral prednisone at a dose of 30-35 mg/day for 3-5 days is the recommended glucocorticoid regimen. 1

First-Line Treatment Options for Gout Flare in CKD Stage 5

• Oral corticosteroids are the preferred first-line treatment for gout flares in patients with severe renal impairment (CKD stage 5) as both colchicine and NSAIDs should be avoided in this population 1
• The recommended dose is 30-35 mg/day of equivalent prednisolone for 3-5 days 1
• Alternative administration options include:
  • Full dose for 5-10 days then stop, OR
  • Full dose for 2-5 days followed by a taper over 7-10 days 1
  • Intra-articular corticosteroid injection (dose varies by joint size) 1
  • Intramuscular triamcinolone acetonide 60 mg (with or without oral prednisone) 1

Rationale for Glucocorticoids in CKD Stage 5

• Colchicine should be avoided in patients with severe renal impairment (GFR <30 mL/min) due to increased risk of toxicity and decreased clearance 1
• NSAIDs are contraindicated in severe renal impairment as they can exacerbate or cause acute kidney injury 2
• Glucocorticoids have been shown to be as effective as NSAIDs for treating gout flares in randomized controlled trials 3
• A double-blind randomized equivalence trial found prednisolone (35 mg/day for 5 days) equivalent to naproxen for treating gout flares 1, 3

Special Considerations in CKD Stage 5

• Monitor for potential exacerbation of comorbidities commonly seen in CKD patients, such as diabetes and hypertension 4
• For patients with frequent flares and contraindications to colchicine, NSAIDs, and corticosteroids, IL-1 blockers may be considered, though current infection is a contraindication 1
• Most clinical trials exclude patients with severe CKD, limiting the evidence base for this population 5
• Early treatment of gout flares leads to better effectiveness, so the "pill in the pocket" approach is recommended for fully informed patients 1

Common Pitfalls to Avoid

• Avoid colchicine in severe renal impairment due to increased risk of neurotoxicity and muscular toxicity 1, 2
• Do not use NSAIDs in CKD stage 5 patients as they can worsen kidney function 2
• Don't delay treatment of acute gout flares; treat as early as possible for best results 1
• Consider long-term urate-lowering therapy (ULT) for patients with recurrent flares, with appropriate dose adjustments for renal function 1

Prophylaxis Considerations

• For patients starting urate-lowering therapy (ULT), prophylaxis against flares is recommended for the first 6 months 1
• In patients with CKD stage 5, low-dose prednisone (<10 mg/day) can be considered for prophylaxis when colchicine and NSAIDs are contraindicated 1
