SAT0421 LONG-TERM URATE-LOWERING THERAPY: IS IT ‘ALL LIFELONG’ NECESSARY?

Background: It has been published that 13% of gout patients remain in a situation of normouricemia after the suspension of urate-lowering therapy (ULT) and, consequently, would not require lifelong treatment. Prospective and specialized follow-up in a tertiary care centre may have favored these positive outcomes, which have not been replicated afterwards. Objectives: To assess the percentage of patients diagnosed with gout, previously followed in Rheumatology consultations, in situation of normouricemia once ULT is suspended. Methods: A transverse study of patients with gout included in an inception cohort and followed in a tertiary care centre. Selected patients were no longer followed by specialized attention. Data, including active prescription of ULT, time since suspension of ULT (if applicable), last serum uric acid (sUA) levels and time for that determination, were procured by electronic history. General data of patients and follow-up were obtained from the database of such cohort. Results: One hundred and forty-two (27.4%) out of 518 patients, with available data accessed by electronic history, lacked prescription of ULT, with an average time since its interruption of 65 months (58, 28-120) and sUA average levels of 7.2±1.7 mg/dl. Nevertheless, 19.2% of these patients showed sUA levels Considering a higher target level of uric acid in the long run and taking into account that these patients had already received treatment for an average mean of 50 months, either in patients with active ULT prescription or patients without it (p=0.35), 41.7% of patients without ULT showed sUA levels Patients without ULT, showing sUA levels 6mg/dl during follow-up (p Conclusion: Between 20% and 40% of patients without a prescription of ULT, previously followed by Rheumatology, showed sUA levels Patients with sUA levels below target during follow-up show a higher rate of sUA levels in target once ULT is suspended.
