Abstract

Aim: To evaluate treatment patterns and clinical factors affecting gout flare in South Korea. Methods: We retrospectively examined data from 401 patients seen at nine rheumatology multicenter clinics, under urate lowering therapy (ULT) more than 6 months after stopping prophylactic medication. Demographic data, clinical and laboratory features were collected at the initiation of ULT, upon stopping prophylaxis, and 6 months after. Results: The mean age was 52.2 years and mean disease duration was 25.0 months. The male-to-female count was 387 : 14. The most common ULT starting agent was allopurinol 83.8%. Colchicine (62.3%) was the most commonly prescribed prophylactic agent. During ULT, 134 of the 401 patients (33.4%) experienced at least one gouty attack in the period from stopping prophylaxis to 6 months later. The duration of prophylaxis was different between those with serum uric acid levels below 6 mg/dL and those over 6 mg/dL (P = 0.001). Of the 179 patients (44.6%) who attained target serum uric acid (SUA) levels (6 mg/dL) at the end of prophylaxis, those taking < 6 months of prophylaxis suffered more frequent flares than those taking it ≥ 6 months (42.9% vs. 26.3%, P = 0.041). The time interval to the first attack after stopping prophylaxis was shorter in the < 6 months group than the ≥ 6 months group (13.5 weeks vs. 22.5 weeks, P = 0.007). Conclusions: Prophylaxis more than 6 months from initiation of ULT, and achieving target SUA (< 6 mg/dL) at the time of stopping prophylaxis is associated with fewer gout flares during ULT.
