Abstract

ObjectiveGout is associated with a higher risk of fracture; however, findings on the associations of hyperuricemia and urate‐lowering therapy (ULT) with the risk of fracture have been inconsistent. We examined whether lowering serum urate (SU) levels with ULT to a target level (i.e., <360 μmoles/liter) reduces the risk of fracture among individuals with gout.MethodsWe emulated analyses of a hypothetical target trial using a “cloning, censoring, and weighting” approach to examine the association between lowering SU with ULT to the target levels and the risk of fracture using data from The Health Improvement Network, a UK primary care database. Individuals with gout who were age 40 years or older and for whom ULT was initiated were included in the study.ResultsAmong 28,554 people with gout, the 5‐year risk of hip fracture was 0.5% for the “achieving the target SU level” arm and 0.8% for the “not achieving the target SU level” arm. The risk difference and hazard ratio for the “achieving the target SU level” arm was –0.3% (95% confidence interval [95% CI] –0.5%, –0.1%) and 0.66 (95% CI 0.46, 0.93), respectively, compared with the “not achieving the target SU level” arm. Similar results were observed when the associations between lowering SU level with ULT to the target levels and the risk of composite fracture, major osteoporotic fracture, vertebral fracture, and nonvertebral fracture were assessed.ConclusionIn this population‐based study, lowering the SU level with ULT to the guideline‐based target level was associated with a lower risk of incident fracture in people with gout.image
