Analysis of risk factors for susceptibility of frequent gout attacks: A case-control study of 579 patients with primary gout

Objective To analyze the risk factors of frequent gout flare, and to evaluate its susceptibility to identify patients with≥2 acute attacks per year. Methods A total of 579 of cases gout patients with no history of taking urate lowering treatment (ULT) in recent 12 months were enrolled. The patients were divided into frequent group (gout episodes≥twice per year) and non-frequent group(gout attacks2, which can predict the frequent flare, and start ULT as earlier as possible. Patients with joints involved at initial diagnosis>2 are at greater risk of frequent gout flare. Key words: Gout; Flare; Frequency; Risk factors; ROC curve
