摘要
Frequent gout attacks in the initial introduction of urate-lowering therapy (ULT) are significant causes of poor drug adherence and ULT discontinuation. Initial low-dose urate-lowering drugs may be effective in reducing gout flares, however, robust evidence is sparse. The aim of this study was therefore to assess the association of initial dose urate-lowering drugs with gout flares in adult males with gout during the initial introduction of ULT.This cohort study obtained data on consecutive gout patients from a single-center gout cohort study from August 2017 to October 2020. A standard questionnaire was applied to collect demographic and clinical information, and biochemical parameters were tested on the same day. The primary end point was to estimate the association of initial dose febuxostat with gout flares, using cox hazard models with inverse probability of treatment weighting (IPTW).A total of 582 gout patients were included in this study. During 6-week follow-up, 71 (12.2%) patients suffered gout flares. In the main analysis using cox hazard models with IPTW, compared with colchicine prophylaxis, initial low-dose febuxostat alone had no statistical significance with the increased risk of gout flares [hazard ratio (HR), 1.26; 95% CI, 0.58-2.72], while initial high-dose febuxostat was associated with an increased risk of gout flares (HR, 3.08; 95% CI, 1.34-7.07).This observational study demonstrated that initial low-dose febuxostat was equally effective in preventing gout flares as colchicine prophylaxis, while initial high-dose febuxostat alone was associated with an increased risk of gout flares.
