Abstract
Cisplatin (Cis) is a platinum-based antineoplastic drug used in various types of cancers. This drug can induce nephrotoxicity as a cause of acute kidney injury (AKI) by inducing oxidative stress and inflammation. Empagliflozin (Empa) is a newly developed inhibitor of sodium-glucose cotransporter-2 (SGLT2) approved as an antidiabetic medication for patients with type 2 diabetes mellitus. In addition to its blood glucose-lowering effect, Empa has been shown to exert anti-inflammatory and anti-oxidant properties. The current study aimed to investigate the protective effects of Empa on Cis-induced nephrotoxicity in rats. Male Wistar albino rats were divided into five groups, each of six rats: Sham group (received vehicle for 7 days), Control group (received vehicle for 7 days and Cis injection on day 2), Cis + Empa10 (received 10mg/kg Empa for 7 days and Cis injection on day 2), Cis + Empa30 (received 30mg/kg Empa for 7 days and Cis injection on day 2) and, Empa 30 (received 30mg/kg Empa for 7 days). One day after the last injection in each group, rats were weighed and then sacrificed to analyze the hematological, biochemical, and histological parameters. Cis markedly increased levels of inflammatory parameters such as renal tumor necrosis factor-alpha (TNF-α), interleukin (IL)-1β, and myeloperoxidase (MPO) activity. Notably, malondialdehyde (MDA), blood urea nitrogen (BUN), and creatinine levels were enhanced after Cis administration. Also, the chemotherapeutic agent significantly reduced antioxidant indicators such as renal catalase (CAT), glutathione peroxidase (GpX), and superoxide dismutase (SOD). Furthermore, histopathological examinations also revealed severe renal damage following Cis treatment which was improved by Empa administration. Empa treatment at both doses (10 mg/kg and 30 mg/kg) reversed Cis-induced changes in all the above renal parameters. In conclusion, Empa has protective effects on Cis-induced nephrotoxicity by inhibition of oxidative stress and inflammation.
