Higher doses of antioxidant vitamins C and E have been proved to be effective against cisplatin-induced nephrotoxicity in animals. However, the possible effective equivalent dose in human was found to be higher than that of the upper tolerable intake level (UL) for these vitamins. Hence, the current study was aimed to evaluate the protective effect of co-supplementation of single and multi doses of vitamins C and E against cisplatin-induced acute renal failure in mice. Single dose of vitamin C (500 mg/kg), vitamin E (500 mg/kg), and vitamin C plus vitamin E (250 mg/kg each) were administered orally 1 h prior to cisplatin (12 mg/kg, i.p) injection, whereas in a multidose study they were administered I h prior, and 24 and 48 h after the cisplatin injection. Serum urea and creatinine levels were estimated 72 h after the injection of cisplatin. Renal concentrations of glutathione (GSH) and malondialdehyde (MDA) were also determined. Co-supplementation of vitamins significantly protected the cisplatin-induced increased levels of serum urea, creatinine, renal MDA, and the declined renal GSH level. Administration of single and multi doses of vitamin C plus E (250 mg/kg each) rendered significant nephroprotection. Therefore, accounting for the rare side effect from high intake of vitamins C and E observation of this study indicates that a multidose combination therapy of these vitamins at their lower doses can be effective in protecting the cisplatin-induced renal damage. The protection is partially mediated through the antioxidant effect of the vitamins. (C) 2008 Elsevier GmbH. All rights reserved.
