The first histopathological evidence of trimetazidine for the prevention of contrast-induced nephropathy

Abstract

Aim: We aimed to investigate the prophylactic effects of trimetazidine (TMZ) against contrast-induced nephropathy (CIN) in rat kidneys. Methods and results: 28 Wistar rats were divided into 4 groups of 7 rats each (control (C), contrast media (CM) TMZ, trimetazidin + contrast media groups (TMZ + CM). The administration of TMZ solution was done on d2, d3 and d4. Fifth day, contrast media was administered at a single dose. On d6 scarification was performed. The oxidant/antioxidant parameters were measured and histopathological scores were performed in kidney tissues. Most of the histopathological scores were significantly higher in the CM group as compared to other groups. Moreover, the scores of the TMZ + CM and C groups were not statistically different. CM group, had significantly higher levels of MDA compared to the C and CM + TMZ groups (562.82 ± 38.15 vs. 419.15 ± 49.01 and 507.34 ± 14.16 01 nmol/mg protein respectively) (p < 0.001). CM group had significantly lower levels of SOD as compared to C, CM + TMZ and TMZ groups (p < 0.05). Conclusion: To the best of our knowledge, this study for the first time, histopathologically demonstrated the effectiveness of TMZ for the prevention of CIN.
