Management and Treatment of Gout
Acute Gout Flare Treatment
For acute gout attacks, initiate treatment immediately with colchicine, NSAIDs, or oral corticosteroids—all three are equally effective first-line options, and the choice depends on patient comorbidities and contraindications rather than efficacy differences. 1, 2, 3
First-Line Agent Selection
Colchicine is most effective when started within 12 hours of symptom onset, using low-dose regimen: 1.2 mg (two 0.6 mg tablets) at first sign, followed by 0.6 mg one hour later, with maximum 1.8 mg in first 24 hours 1, 2, 3
- Low-dose colchicine has similar efficacy to high-dose but significantly fewer adverse effects 3
- Critical contraindication: Avoid in severe renal impairment (CrCl <30 mL/min) or patients on strong CYP3A4/P-glycoprotein inhibitors (clarithromycin, ritonavir, ketoconazole) due to risk of fatal toxicity 3, 4
NSAIDs at full anti-inflammatory doses are equally effective, with no clinically significant differences between agents 2, 3
Oral corticosteroids (prednisone or prednisolone 30-35 mg daily for 3-5 days) are the safest option for patients with renal impairment, cardiovascular disease, or gastrointestinal contraindications to NSAIDs 2, 3
- Particularly effective for polyarticular flares with systemic inflammation 3
Special Situations
Monoarticular or oligoarticular flares (1-2 large joints): Intra-articular corticosteroid injection is highly effective and preferred 3
Patients unable to take oral medications: Use parenteral glucocorticoids (intramuscular or intravenous) over IL-1 inhibitors 3
Severe polyarticular attacks: Combination therapy with full doses of two agents (e.g., colchicine + NSAIDs, oral corticosteroids + colchicine, or intra-articular steroids with any other modality) is appropriate 1
IL-1 inhibitors (canakinumab 150 mg subcutaneously): Reserved only for patients with contraindications to all first-line agents and frequent flares; absolute contraindication if active infection present 3
Urate-Lowering Therapy (ULT)
Indications for Initiating ULT
- Tophaceous gout (any tophi on physical exam)
- Radiographic damage due to gout
- Frequent gout flares (≥2 attacks per year)
- Chronic kidney disease stage ≥2
- History of urolithiasis
Consider early initiation if: 2
- Young age (<40 years) with very high serum urate (>8 mg/dL)
- First attack with significant comorbidities
Do not initiate after first attack or in patients with infrequent attacks (<2 per year without tophi or joint damage) 2
First-Line ULT: Allopurinol
Allopurinol is the preferred first-line urate-lowering therapy for all patients, including those with moderate-to-severe chronic kidney disease (stage ≥3). 1, 2
- Starting dose: ≤100 mg/day (lower in CKD: 50 mg/day if CrCl 10-20 mL/min; 50-100 mg/day if CrCl 30-50 mL/min) 1, 4
- Titration: Increase by 50-100 mg every 2-4 weeks based on serum urate levels 1, 2
- Target serum urate: <6 mg/dL (360 μmol/L) for all patients; consider <5 mg/dL (300 μmol/L) for patients with tophi to facilitate faster resolution 1
Alternative ULT Agents
Febuxostat: Second-line xanthine oxidase inhibitor; start at <40 mg/day and titrate to achieve target 1
- Can be used without dose adjustment in mild-to-moderate renal impairment 1
Uricosuric agents (probenecid, benzbromarone): Consider for patients who cannot tolerate xanthine oxidase inhibitors 1
- Contraindicated in patients with urolithiasis or uric acid overproduction 5
Pegloticase (uricase): Reserved only for severe refractory gout where all other therapies have failed or are contraindicated 1
Critical ULT Management Principles
Continue ULT without interruption during acute flares—stopping therapy worsens the flare and complicates long-term management. 2, 3
ULT can be started during an acute flare; there is no need to wait for flare resolution. 2, 3
Anti-Inflammatory Prophylaxis During ULT Initiation
When initiating or uptitrating ULT, concomitant anti-inflammatory prophylaxis is mandatory for minimum 3-6 months to prevent treatment-induced flares. 1, 2
Prophylaxis Agent Selection
First-line: Low-dose colchicine 0.5-0.6 mg once or twice daily 1, 3
- Dose adjustment required in renal impairment: 0.3 mg daily if CrCl <50 mL/min; 0.3 mg twice weekly if on dialysis 4
Second-line: Low-dose NSAIDs (e.g., naproxen 250 mg twice daily) with PPI if indicated 1
Third-line: Low-dose prednisone or prednisolone (<10 mg/day) if colchicine and NSAIDs contraindicated, not tolerated, or ineffective 1
Duration of Prophylaxis
Continue prophylaxis for the greater of: 1
- Minimum 6 months, OR
- 3 months after achieving target serum urate in patients without tophi, OR
- 6 months after achieving target serum urate in patients with history of tophi
Extend prophylaxis beyond 6 months if gout attacks continue to occur. 2, 3
Lifestyle Modifications
All patients should receive education on lifestyle modifications: 1, 2
- Weight loss if overweight or obese
- Avoid alcohol, especially beer and spirits
- Eliminate sugar-sweetened beverages and foods high in fructose
- Reduce excessive consumption of red meat and seafood
- Promote low-fat dairy products
- Regular exercise
Monitoring and Follow-Up
- Serum urate levels: Monitor regularly during ULT titration (every 2-4 weeks initially, then every 6 months once at target) 1, 2
- Frequency of gout attacks: Track to assess treatment effectiveness 1
- Renal function and cardiovascular risk factors: Assess at baseline and monitor periodically 1, 2
- Tophi size: Document and monitor for resolution 1
Critical Pitfalls to Avoid
- Delaying treatment of acute flare: Early initiation is the single most important determinant of success, not which agent is chosen 3, 5
- Using colchicine with CYP3A4/P-gp inhibitors or in severe renal impairment: Can result in fatal toxicity 3, 4
- Stopping ULT during acute flare: Worsens the flare and complicates management 2, 3
- Starting allopurinol at high doses: Increases risk of hypersensitivity reactions and precipitates flares 1
- Failing to provide prophylaxis when initiating ULT: Results in treatment-induced flares and poor adherence 1, 2
- Not treating to target serum urate: Subtherapeutic dosing leads to continued flares and disease progression 1
