Extensive structural damage within the kidney must be present before serum creatinine increases. However, a subclinical phase of chronic kidney disease (CKD) usually goes undetected. Here we tested whether experimental subclinical CKD would modify functional and damage biomarker profiles of acute kidney injury (AKI). Subclinical CKD was induced in rats by adenine or aristolochic acid models but without increasing serum creatinine. After prolonged recovery (three to six weeks), AKI was induced with a subnephrotoxic dose of cisplatin. Urinary levels of kidney injury molecule-1 (KIM-1), cytochrome C, monocyte chemotactic protein-1 (MCP-1), clusterin, and interleukin-18 increased during CKD indu..View full abstract
