Objectives

Narrative objectives1

Xanthine oxidase inhibitors are widely used for patients with hyperuricemia and chronic kidney disease (CKD); however, their renoprotective effects remain controversial. Meanwhile, there is currently a paucity of reports regarding the effects of uricosuric agents on renal function in this patient population. The purpose of this study is to investigate the impact on renal function of switching from a xanthine oxidase inhibitor to a uricosuric agent in patients with hyperuricemia and CKD.

Assessment

Primary outcomes

Patients were switched from the xanthine oxidase inhibitor febuxostat to the selective urate reabsorption inhibitor dotinurad. We compared renal function parameters (serum creatinine, cystatin C, and eGFR), serum uric acid levels, urinary protein, and the fractional excretion of uric acid (FEUA) between baseline (pre-switch) and three months after the switch.
