Effect of Febuxostat on the Endothelial Dysfunction in Hemodialysis Patients: A Randomized, Placebo-Controlled, Double-Blinded Study.

Abstract

BACKGROUND Endothelial dysfunction is an important risk factor for cardiovascular diseases to occur in end-stage renal disease patients. Febuxostat, being a novel xanthine oxidase inhibitor, is apparently having a beneficial role in improving the endothelial dysfunction; however, data among hemodialysis patients are still limited. METHODS A prospective, placebo-controlled, block-randomized, double-blinded study was carried out to evaluate the effect of oral febuxostat on the endothelial dysfunction in hemodialysis patients. Fifty-seven eligible hemodialysis patients were randomly assigned to either the drug group (40 mg thrice weekly) or the placebo group. Serum Asymmetric dimethylarginine (ADMA), Serum uric acid (UA), and serum high sensitivity C-reactive protein (hsCRP) were measured at baseline and at the end of a 2-month study. Serum alanine aminotransferase (ALT), serum aspartate aminotransferase (AST), and the occurrence of pancytopenia were tested as safety parameters at baseline and at the end of study. RESULTS Serum UA significantly decreased from 7.5 ± 0.8 to 5.1 ± 1.2 mg/dL in the febuxostat group, while it did not change significantly in the placebo group. Treatment with febuxostat resulted in a significant decrease in the serum ADMA level from 1.027 ± 0.116 to 0.944 ± 0.104 µmol/L and the serum hsCRP level from 12.5 ± 1.65 to 12.1 ± 1.70 mg/L. Testing of serum ALT, serum AST, and pancytopenia revealed no significant difference in both groups. CONCLUSION Febuxostat appears to improve hyperuricemia and endothelial dysfunction and ameliorate inflammation in hemodialysis patients with no safety concerns.
