Objectives

Narrative objectives1

The aim of the study is to retrospectively evaluate the effect of serum uric acid level on eGFR in patients with hyperuricemia treated with topiroxostat for at least 24 months between January 1, 2015 and April 30, 2021.

Assessment

Primary outcomes

Patients will be divided into 2 groups: Low group (patients with a mean uric acid level of 6 mg/dl or less for 6 months or longer at 12 months or later) and High group (those other than the above). The change in eGFR from baseline to the final evaluation at 24 months will be compared.

Key secondary outcomes

(1)Uric acid level
1)Change from baseline to 24 months(by GFR category*)

(2)Serum creatinine level
1)Change from baseline to 24 months
2)Doubling rate from baseline to 24 months(by uric acid level*)

(3)eGFR
1)Change from baseline to 24 months
2)Change from baseline to 24 months(by GFR category)
3)30% reduction rate from baseline to 24 months(by uric acid level)

*By GFR category: GFR category at baseline(G3a, G3b, G4, G5)
*By uric acid level: The uric acid value at baseline is divided into 6 groups(<6.0,6.0-6.9,7.0-7.9,8.0-8.9,9.0-9.9,>10).

Other

Other related information

1)It is suggested that hyperuricemia is related to Chronic Kidney Disease(CKD)and there is a possibility for hyperuricemia to be its risk factor.
2)The evidence is insufficient to prove the possibility for antihyperuricemic to prevent CKD onset and its progression.
3)The effect of control of serum uric acid level by prolonged antihyperuricemic administration on renal function is not also clarified.
4)This study aims to evaluate the relationship between control of serum uric acid level by prolonged administration of topiroxostat as antihyperuricemic and renal function(eGFR) via collecting data of hyperuricemia patients with CKD retrospectively.
