Amphotericin B-induced nephrotoxicity: characterization of blood and urinary biochemistry and renal morphology in mice
2009
This study was conducted to characterize blood and urinary biochemistry, and renal morphology, after single or 1-week repeated dosing of mice with the polyene macrolide antibiotic, amphotericin B (AMB). AMB was intravenously administered to mice at 2 or 4 mg/kg for the single-dose experiment or once daily at 1 or 2 mg/kg for 1 week for the repeated-dose experiment. The most prominent histopathological findings included necrosis of the tubular epithelial cells in the thick ascending limb of Henle’s loop in the renal outer medulla at a single dose of 2 or 4 mg/kg, and the severity of the lesion was dose-dependent. Blood chemistry and urinalysis revealed several changes suggestive of renal dysfunction such as reduction of plasma filtration ability (increases in plasma creatinine and blood urea nitrogen, a decrease in creatinine clearance) and polyuria accompanied with dehydration (decrease in renal water reabsorption, increases in plasma total protein and albumin) at a dose of 4 mg/kg in the single-dose expe...
