What is the best management approach for a patient with recurrent pain and swelling in the left foot and a history of hyperuricemia?

Management of Recurrent Gout with Hyperuricemia

This patient requires immediate treatment of the acute attack followed by long-term urate-lowering therapy with allopurinol, starting at 100 mg daily and titrating upward every 2-5 weeks to achieve serum uric acid <6 mg/dL, along with prophylactic anti-inflammatory medication for at least 8 weeks (preferably 6 months) when initiating urate-lowering therapy. 1

Acute Attack Management

Do not stop any established urate-lowering therapy during the acute attack - this is a critical error that worsens outcomes. 1

For immediate symptom relief, initiate treatment within 24 hours using one of these first-line options: 2, 1

• Low-dose colchicine (0.5-0.6 mg two to three times daily) - equally effective as high-dose regimens but with significantly fewer gastrointestinal adverse events 2, 1
• NSAIDs at full anti-inflammatory doses - the specific NSAID chosen matters less than how quickly treatment is initiated 2
• Corticosteroids (oral, intravenous, or intra-articular) - particularly appropriate when NSAIDs or colchicine are contraindicated, with a favorable safety profile 2, 1

COX-2 inhibitors cause fewer total adverse events (38% vs 60%) and fewer withdrawals (3% vs 8%) compared to traditional NSAIDs, making them preferable when available. 2

Long-Term Urate-Lowering Therapy

The fundamental goal is reducing serum uric acid below 6 mg/dL to prevent future attacks, dissolve existing crystal deposits, and prevent tophi formation. 1

Allopurinol as First-Line Therapy

Start allopurinol at 100 mg daily, then titrate upward every 2-5 weeks based on serum uric acid monitoring until the target of <6 mg/dL is achieved. 1, 3

• The dose can and should be raised above 300 mg daily, even in patients with renal impairment, provided there is adequate patient education and monitoring for toxicity 1
• With creatinine clearance 10-20 mL/min, use 200 mg daily; with clearance <10 mL/min, do not exceed 100 mg daily 3
• Febuxostat is the appropriate substitute only in cases of allopurinol intolerance, adverse events, or failure of dose titration - not as initial therapy 1

Critical Prophylaxis Requirement

All patients starting urate-lowering therapy require prophylactic anti-inflammatory medication to prevent acute flares during the initial treatment period. 2, 1

• Use low-dose colchicine (0.5-0.6 mg once or twice daily) or low-dose NSAIDs 2, 1
• Continue prophylaxis for more than 8 weeks - the rate of acute gout flares approximately doubles when prophylaxis is discontinued after only 8 weeks 2
• Optimal duration is 6 months - trials continuing prophylaxis for 6 months showed no increase in acute flares 2

Monitoring Strategy

Monitor serum uric acid levels every 2-5 weeks during dose titration to ensure levels remain below 6 mg/dL. 1

Non-Pharmacologic Management

Patient education and lifestyle modifications are core aspects of management and should be implemented alongside pharmacologic therapy: 2

• Weight loss if obese 2
• Reduced alcohol consumption, especially beer 2
• Dietary modifications (though evidence for specific dietary interventions on clinical outcomes is insufficient) 2
• Address associated comorbidities: hyperlipidemia, hypertension, hyperglycemia, obesity 2

Common Pitfalls to Avoid

Stopping urate-lowering therapy during an acute attack - this worsens outcomes and should never be done. 1

Inadequate prophylaxis duration - stopping anti-inflammatory prophylaxis before 8 weeks (ideally 6 months) doubles the risk of acute flares. 2

Underdosing allopurinol - many providers hesitate to exceed 300 mg daily, but higher doses are often necessary and safe with appropriate monitoring. 1

Delaying treatment beyond 24 hours - early initiation is the most important determinant of therapeutic success for acute attacks. 2, 4

Using high-dose colchicine - low doses are equally effective with significantly fewer adverse effects. 2, 1
