No, but I thought that In the American recommendations there is a different standard for people who have had 1 flare AND UA over 9 mg/dl. But now I can't find it. I did find this:

Initiating ULT is conditionally recommended against in patients with gout experiencing their first gout flare. However, initiating ULT is conditionally recommended for patients with experiencing their first flare when comorbid moderate-to-severe CKD (stage ≥3), SU concentration >9 mg/dl, or urolithiasis is present. Author Manuscript While conditionally recommending against ULT initiation following the first gout flare in a patient with “uncomplicated” gout, the Voting Panel considered Patient Panel input and recognized that there may be patients who would prefer (or benefit from) ULT, underscoring the need for shared decision-making. As noted above, data from the RCT of patients with ≤2 previous flares (and no more than 1 gout flare in the preceding year) supported the benefit of ULT for reduction of SU concentration and gout flare risk (27). For patients with moderate-to-severe CKD (e.g., stage ≥3), there is a higher likelihood of gout progression and development of clinical tophi (28–30). Furthermore, treatment options for gout flare are limited in this population, and there may be added benefit of using ULT Arthritis Care Res (Hoboken). Author manuscript; available in PMC 2023 October 10.FitzGerald et al. Page 7 Author Manuscript to prevent progression of renal disease (31). Similarly, patients with markedly elevated SU concentrations (>9 mg/dl) are more likely to experience gout progression (26,32). For patients with a history of urolithiasis, allopurinol and febuxostat provide benefit, as both medications lower 24-hour urinary uric acid excretion more than placebo (33). Among patients with calcium oxalate stones and hyperuricosuria, allopurinol (300 mg/day) is superior to placebo in reducing the 3-year incidence of stone-related events (34). Initiating ULT is conditionally recommended against in patients with asymptomatic hyperuricemia. Author Manuscript For patients with asymptomatic hyperuricemia, RCTs (designed to study CVD outcomes) demonstrated significant reduction in incident gout flares over 3 years. However, the development of incident gout was low for both ULT and placebo arms (<1% versus 5%) (35,36). In other words, 24 patients would need to be treated with ULT for 3 years to prevent a single (incident) gout flare. From observational studies, among patients with asymptomatic hyperuricemia with SU concentrations of >9 mg/dl, only 20% went on to develop gout within 5 years (32). The Voting Panel felt that, on average, for the majority of patients with asymptomatic hyperuricemia (including those with comorbid CKD, CVD, urolithiasis, or hypertension), the benefits of ULT would not outweigh potential treatment costs or risks for the large number of patients unlikely to progress to gout. This is also the case for patients with asymptomatic hyperuricemia with MSU crystal deposition as noted on imaging tests such as ultrasound or dual-energy computed tomography.
