Cisplatin (CDDP) is a potent nephrotoxin, and nephrotoxicity is its most important dose-limiting toxicity. In this study, we aimed to investigate the role of recombinant human erythropoietin (rhEPO) in the protection of cisplatin-induced nephrotoxicity and compare its efficacy with the cell-protective agent amifostine. All experiments were conducted on female Wistar albino rats. Animals were randomly assigned to four groups, each including six rats. Group A received only CDDP, group B received CDDP plus rhEPO, group C received CDDP plus amifostine, and group D received only rhEPO. At the end of 7 wk, hemoglobin (Hgb), hematocrite (Htc), blood urea nitrogen (BUN), and creatinine (Cr) levels were determined and kidneys of the rats were removed. The weights of the kidneys were measured and sent for histopathological examination. Proximal tubules from four areas of the kidney (outer cortex, inner cortex, the medullary ray, and outer stripe of outer medulla [OSOM]) were evaluated. There were statistically significant differences among the groups in terms of tubular scores, including overall renal tubular score, cortex, inner cortex, OSOM, and medullary ray tubular scores, and Hie levels. Group A rats had the worse tubular scores in all categories when compared to group D rats. When the results of groups B and C were compared, there were no differences in terms of BUN, Cr levels, and tubular scores, but the Hie level was significantly higher in group B. Group B rats had better overall and OSOM tubular scores when compared to group A. Group C also had better overall and OSOM tubular scores compared to group A. The present study showed for the first time that rhEPO plays an important role in the prevention of cisplatin-induced nephrotoxicity and it is as effective as amifostine.
