Cisplatin is a chemotherapeutic agent inducing liver and kidney damage. In this study, we intended to investigate the impact of kefir beverage, an essential probiotic and functional food, on liver and kidney damage induced by cisplatin. Wistar albino rats were divided into four groups: Control, Cisplatin (single dose of 7 mg/kg, intraperitoneal), Kefir (2 ml/d, 7 d, oral gavage), and Cisplatin+Kefir (CK). At the end of day 7, animals were euthanized. Blood, kidney, and liver tissue samples were collected. For both tissues, biochemically ALT, AST, Urea, Creatine; histomorphologically, hematoxylin-eosin, Masson's Trichrome, and immunohistochemical staining of caspase-3, a marker of apoptosis, were performed. Serum urea and creatinine levels of the Cisplatin group were significantly higher than the Control group (p<0.05). In the CK group, kefir consumption decreased urea and creatinin levels approached to Control and Kefir groups. Cisplatin resulted in higher ALT and AST activities, indicating hepatocellular damage, compared to the Control group (p<0.05). Kefir consumption decreased ALT activities approached to both the Control and Kefir group. Histomorphological observations were in agreement biochemical results. In liver and kidney tissues, structural damage was observed with an increase in collagen fibers in the Cisplatin group, and Caspase-3 activity was immunohistochemically higher than in the other groups. In the CK group, collagen fiber increase, structural damage, and Caspase-3 activities were less than in the Cisplatin group. Kefir consumption alleviated liver and kidney damage. However, more research is required to understand such effect of kefir better.
