Comparative Study of Real-Life Management Strategies in Gout: Data From Two Protocolized Gout Clinics.

Area of Science:

• Rheumatology
• Clinical Medicine
• Pharmacoeconomics

Background:

• Gout management aims to reduce flares and serum uric acid (UA) levels.
• Different treatment strategies exist, including strict UA targets and patient-centered approaches.
• Comparing the efficacy and safety of these strategies is crucial for optimizing patient care.

Purpose of the Study:

• To compare the outcomes of two gout clinics employing distinct treatment strategies: a strict serum UA target versus a patient-centered (PC) approach.
• To evaluate the proportion of patients achieving target serum UA levels and remaining flare-free.
• To assess treatment intensification and adverse events associated with each strategy.

Main Methods:

• A comparative study included newly diagnosed gout patients with a 9-15 month follow-up.
• One clinic used a strict serum UA (≤0.30 mmoles/liter) strategy with early uricosuric addition.
• The other clinic employed a PC strategy based on shared decision-making regarding UA levels and patient satisfaction.

Main Results:

• The strict UA strategy group (83%) showed a non-significantly higher proportion of patients reaching serum UA ≤0.36 mmoles/liter compared to the PC group (74%) (P=0.10).
• Flare-free rates were also non-significantly higher in the UA strategy group (46%) versus the PC group (36%) (P=0.15).
• The UA strategy involved significantly more allopurinol monotherapy (60% vs 73%; P=0.05) and treatment intensification, with no difference in adverse events (20% vs 23%; P=0.55).

Conclusions:

• A strict serum UA target strategy for gout management resulted in a non-significantly higher proportion of patients achieving target UA levels and remaining flare-free.
• This was achieved with significantly more treatment intensification, suggesting a trade-off between target achievement and therapeutic escalation.
• The study highlights the potential role of sample size in determining statistical significance and warrants further investigation into optimal gout treatment paradigms.
