Gout prevalence and management strategies among patients with moderate to advanced chronic kidney disease.

INTRODUCTION

Gout commonly coexists with chronic kidney disease (CKD), with prevalence increasing as kidney function declines. Despite its burden, data on monitoring and treatment practices in CKD are limited. This study describes the prevalence, characteristics, and management of gout in non-dialysis CKD patients.

METHODS

Cross-sectional data were analyzed from 3,524 stages 3a-5 CKD patients in the Chronic Kidney Disease Outcomes and Practice Patterns Study (CKDopps) in Brazil (n = 942) and the United States (n = 2,582) at enrollment (2013-2022). History of gout was extracted from medical records.

RESULTS

Gout prevalence was 18.7% overall-20.5% in the US and 13.9% in Brazil-higher in stages 4-5 vs. 3a-3b CKD. Allopurinol was most used (Brazil 75%; US 62%). Colchicine (13%) and febuxostat (8%) were reported in the US but rarely in Brazil. Uric acid was measured in 70% of Brazilian vs. 33% of US gout patients.

CONCLUSIONS

Gout is common in CKD, with notable cross-country differences in monitoring and treatment.
