Aim. In this study, we aimed to investigate the effects of febuxostat, a novel
inhibitor of xanthine oxidase (XO), on renal damage in streptozotocin- (STZ-)
induced diabetic rats. Methods. Diabetes was induced by the intraperitoneal
injection of STZ in male Sprague-Dawley rats. Sham-injected rats served as
controls. The control and diabetic rats were treated with and without febuxostat
for 8 weeks, respectively. Fasting blood and 24-h urine samples were collected
every 4 weeks. Rat livers were extracted for detecting gene expression, content,
and bioactivity of XO. Results. Diabetic rats showed significantly increased
serum uric acid (SUA), serum creatinine (SCr), and urea nitrogen (BUN) levels.
Daily urinary albumin (UAE), uric acid (UUA), and creatinine (UCr) excretion were
also significantly increased in these rats. In diabetic rats, at week 8,
febuxostat decreased SUA by 18.9%, while UAA was increased by 52.0%. However, UCr
and urinary urea nitrogen (UUN) levels remained unchanged, while SCr and BUN
levels decreased by >30% in these rats. Although hepatic gene expression,
content, and activity of XO increased significantly in diabetic rats, febuxostat
only slightly decreased its content. Conclusions. Febuxostat significantly
attenuated renal damage in STZ-induced diabetic rats in addition to exerting
hypouricemic effect.
