What is the recommended prednisone (corticosteroid) dosage for a patient with Chronic Kidney Disease (CKD) and an estimated Glomerular Filtration Rate (eGFR) of 16ml/min experiencing an acute gouty attack?

Prednisone Dosage for Acute Gout in Advanced CKD

For a patient with CKD and eGFR of 16 mL/min experiencing an acute gouty attack, use oral prednisone 0.5 mg/kg per day (or 30-35 mg/day) for 5-10 days at full dose then stop, OR for 2-5 days at full dose then taper over 7-10 days. 1

Rationale for Corticosteroids in Severe CKD

• Corticosteroids are the preferred first-line treatment for acute gout in patients with severe renal impairment (eGFR <30 mL/min). 1
• Both colchicine and NSAIDs should be avoided in severe CKD: colchicine requires significant dose reduction and carries risk of toxicity, while NSAIDs can precipitate acute kidney injury. 1, 2
• The 2024 KDIGO guidelines specifically recommend low-dose colchicine or intra-articular/oral glucocorticoids as preferable to NSAIDs for symptomatic treatment of acute gout in CKD. 1

Specific Dosing Recommendations

Standard Oral Regimen

• Prednisone 0.5 mg/kg per day (typically 30-40 mg for most adults) 1
• Alternative: Prednisolone 30-35 mg/day for 3-5 days 1
• Duration options: 1
  • 5-10 days at full dose then stop abruptly, OR
  • 2-5 days at full dose then taper over 7-10 days

Alternative Routes

• Intramuscular: Triamcinolone acetonide 60 mg as single dose, followed by oral prednisone as above 1
• Intra-articular injection: Dose varies by joint size, can be used with or without oral therapy 1

Important Considerations for Advanced CKD

• No dose adjustment of corticosteroids is required based on kidney function alone - unlike colchicine and NSAIDs, corticosteroids are not renally cleared and maintain efficacy in advanced CKD. 1
• With eGFR of 16 mL/min (CKD Stage 5), this patient is approaching kidney failure, making corticosteroids the safest anti-inflammatory option. 1
• Colchicine would require dose reduction to 0.5-0.6 mg once daily (or less) at this level of kidney function and carries significant risk of neurotoxicity and myotoxicity. 1

Combination Therapy for Severe Attacks

• For severe polyarticular gout or involvement of multiple large joints, consider combination therapy: 1
  • Oral corticosteroids plus colchicine (at reduced dose for CKD), OR
  • Intra-articular steroids plus oral corticosteroids
• The task force did not recommend combining NSAIDs with corticosteroids due to synergistic gastrointestinal toxicity concerns. 1

Clinical Pitfalls to Avoid

• Do not use NSAIDs - they are contraindicated in severe renal impairment and can worsen kidney function. 1, 2
• Avoid standard-dose colchicine - the typical acute gout loading dose (1 mg followed by 0.5 mg) is inappropriate at eGFR 16 mL/min due to accumulation and toxicity risk. 1
• Monitor for corticosteroid side effects including hyperglycemia, hypertension, and fluid retention, which may be more problematic in advanced CKD. 1
• Ensure the offending drug is discontinued and initiate or optimize urate-lowering therapy after the acute attack resolves. 1

Long-term Management Context

• After treating the acute attack, this patient should be considered for urate-lowering therapy with xanthine oxidase inhibitors (allopurinol with dose adjustment or febuxostat) to prevent recurrent attacks. 1, 3
• Prophylactic low-dose corticosteroids (<10 mg/day prednisone) may be used when initiating urate-lowering therapy, though evidence for efficacy is sparse and requires careful risk-benefit assessment in advanced CKD. 1
