Management of Gout
Gout management requires a dual approach: aggressive early treatment of acute flares with colchicine, NSAIDs, or corticosteroids, combined with lifelong urate-lowering therapy targeting serum uric acid <6 mg/dL for patients with recurrent attacks, tophi, or chronic kidney disease. 1, 2
Acute Gout Flare Management
Treat acute flares as early as possible—ideally within 12-24 hours of symptom onset—as timing is the most critical determinant of therapeutic success. 2, 3
First-Line Treatment Options (Choose One or Combine):
Colchicine: Loading dose of 1 mg followed by 0.5 mg one hour later (total 1.5 mg on day 1), then 0.5 mg daily. Most effective when started within 12 hours of symptom onset. 2, 1
NSAIDs: Use full anti-inflammatory doses with proton pump inhibitor gastroprotection when appropriate. The specific NSAID chosen matters less than early initiation. 2, 3
Corticosteroids: Oral prednisolone 30-35 mg/day for 3-5 days, or intra-articular injection for monoarticular disease. Particularly useful when NSAIDs or colchicine are contraindicated. 2, 1
Non-Pharmacologic Measures:
- Topical ice application and rest of the inflamed joint provide adjunctive benefit. 3
Indications for Urate-Lowering Therapy (ULT)
Initiate lifelong ULT for any patient with: 1, 2
- Tophus or tophi (by clinical exam or imaging)
- Frequent attacks (≥2 per year)
- Chronic kidney disease stage 2 or worse
- Past urolithiasis
- Radiographic damage attributable to gout
- Chronic gouty arthritis
Consider ULT from first presentation of disease according to EULAR guidelines. 1
Urate-Lowering Therapy: Treat-to-Target Approach
The target serum uric acid is <6 mg/dL (360 μmol/L), maintained lifelong. For severe gout with tophi, target <5 mg/dL (300 μmol/L) to improve disease signs and symptoms. 1, 2
First-Line ULT:
Allopurinol is the preferred first-line agent, including for patients with moderate-to-severe chronic kidney disease (stage ≥3). 1, 2, 4
- Starting dose: 100 mg daily 4, 2
- Titration: Increase by 100 mg every 2-4 weeks (or weekly per FDA label) until target serum urate is achieved 4, 1
- Typical maintenance dose: 200-300 mg/day for mild gout; 400-600 mg/day for moderately severe tophaceous gout 4
- Maximum dose: 800 mg/day in divided doses 4
- Renal dosing adjustments: 4
- CrCl 10-20 mL/min: 200 mg daily maximum
- CrCl <10 mL/min: 100 mg daily maximum
- CrCl <3 mL/min: extend interval between doses
Important caveat: Consider HLA-B*5801 testing before initiating allopurinol in high-risk populations (Koreans with stage 3 or worse CKD; Han Chinese and Thai irrespective of renal function) to prevent severe hypersensitivity reactions. 1
Second-Line and Alternative ULT Options:
If serum urate target cannot be achieved with appropriately dosed allopurinol: 1
Febuxostat: Can be substituted for allopurinol in cases of drug intolerance or after failure of upward dose titration. Should not be used in combination with allopurinol. 1
Uricosuric agents: 1
- Probenecid: First choice among uricosurics for monotherapy, but not recommended if CrCl <50 mL/min
- Contraindications for uricosurics: History of urolithiasis, elevated urinary uric acid indicating overproduction
- Monitoring: Measure urinary uric acid before initiation and continue monitoring during therapy
- Risk mitigation: Consider urine alkalinization (e.g., potassium citrate) with urine pH monitoring, plus increased fluid intake (≥2 liters daily urinary output) to prevent urolithiasis
Combination therapy: Add a uricosuric agent (probenecid, fenofibrate, or losartan) to a xanthine oxidase inhibitor, or vice versa. 1
Refractory Gout:
Pegloticase is appropriate for patients with severe gout disease burden and refractoriness to, or intolerance of, conventional and appropriately dosed ULT. It is not recommended as first-line therapy. 1
- Discontinue all oral ULT agents during pegloticase therapy to avoid masking loss of efficacy and increased risk of infusion reactions. 1
Flare Prophylaxis During ULT Initiation
Mandatory prophylaxis for at least 3-6 months when initiating or adjusting ULT to prevent mobilization flares. 2, 5
Prophylaxis Options:
Colchicine 0.5-1 mg daily: First choice for prophylaxis 2, 5
- Reduce to 0.5 mg daily or every other day if CrCl 30-50 mL/min 2
Low-dose NSAIDs: Alternative if colchicine is contraindicated or not tolerated 5
Low-dose corticosteroids: Alternative option 2
Continue prophylaxis until: 1
- Serum urate has been normalized
- Patient has been free from acute gouty attacks for several months
- All palpable tophi and chronic gouty arthritis symptoms have resolved
Lifestyle and Dietary Modifications
Comprehensive lifestyle counseling reduces both hyperuricemia and mortality. 2, 5
Dietary Recommendations:
- Alcohol (especially beer and spirits)
- Sugar-sweetened drinks and high-fructose corn syrup
- Excessive red meat and organ meats
- Shellfish and seafood
- Low-fat or nonfat dairy products
- Vegetables
- Regular exercise
- Weight loss if obese
- Cherry or cherry juice extract (may reduce attack frequency) 6
- Vitamin C supplementation (may lower serum uric acid) 6
Medication Adjustments:
Substitute diuretics if possible, as they promote hyperuricemia. 1, 5
Consider switching to medications with uricosuric properties: 1, 2
- Losartan (modest uricosuric effects) for hypertension
- Calcium channel blockers for hypertension
- Fenofibrate (has uricosuric properties) for hyperlipidemia
Patient Education
Patient education is the single most important intervention, increasing adherence to ULT to 92% at 12 months. 5
Core knowledge points to convey: 5, 6
- Gout is a chronic disease requiring lifelong management
- Hyperuricemia causes crystal deposition leading to attacks and joint damage
- ULT prevents future attacks and dissolves existing crystals
- Patients should self-medicate acute flares at first warning symptoms
- Do not discontinue ULT during acute flares
Common Pitfalls to Avoid
Critical errors that compromise outcomes: 2
- Delaying treatment beyond 24 hours of acute flare symptom onset
- Discontinuing ULT during acute flares (continue ULT and add anti-inflammatory therapy)
- Inadequate prophylaxis duration when initiating ULT (must continue ≥3-6 months)
- Using high-dose colchicine regimens (outdated; use low-dose protocol)
- Insufficient allopurinol dosing (must titrate to achieve target serum urate, not stop at arbitrary dose)
- Failing to monitor serum urate levels to confirm target achievement
- Treating asymptomatic hyperuricemia (not indicated per FDA label and guidelines) 4, 5
Comorbidity Screening and Management
Systematic screening for cardiovascular comorbidities is mandatory for all gout patients, as these interventions reduce both hyperuricemia and mortality. 2, 5
Screen for: 5
- Renal impairment
- Coronary heart disease
- Hypertension
- Obesity
- Metabolic syndrome
- Type 2 diabetes
Long-Term Management Strategy
After achieving target serum urate and resolution of all symptoms: 1
- Continue all measures (including pharmacologic ULT) needed to maintain serum urate <6 mg/dL indefinitely
- Regularly monitor serum urate levels
- Monitor for ULT side effects
- Maintain lifestyle modifications
Referral to specialist should be considered for: 1
- Unclear etiology of hyperuricemia
- Refractory signs or symptoms of gout
- Difficulty reaching target serum urate, particularly with renal impairment
- Multiple or serious adverse events from pharmacologic ULT
