Comparative Levels of Urinary Biomarkers of Renal Injury and Inflammation Among Patients With Diabetic Nephropathy With or Without Hyperuricemia.

Background: The association between hyperuricemia and development of progressive chronic kidney disease has received increasing attention in recent years. Recent preclinical studies have shown that non-crystalline uric acid can induce renal-specific arteriolopathy, leading to renal injury and tubulointerstitial inflammation.

Methods: We conducted a open-label cross-sectional study of 25 patients with chronic kidney disease stage III (estimated glomerular filtration rate [eGFR], 7.
