{Abstract}: Colistin, a multidrug-resistant gram-negative bacterial infection medication, has been associated with renal impairment and failure. Trans-sodium crocetinate (TSC), a saffron-derived chemical recognized for its antioxidant and nephroprotective properties, was studied in this study to determine its potential to alleviate the nephrotoxic effects of colistin. Forty-two male Wistar rats were randomly classified into seven groups (n = 6): (1) control (normal saline, 12 days, i.p.), (2) colistin (22 mg/kg, 7 days, i.p.), (3-5) colistin + TSC (25, 50, and 100 mg/kg, 12 days, i.p., starting from 5 days before colistin), (6) TSC (100 mg/kg, 12 days, i.p.), (7) colistin + vitamin E (100 IU/kg, 12 days, i.p). On day 13, the rats were euthanized and the serum content of creatinine, BUN, Na+, and K+, as well as oxidative stress (GSH, MDA, SOD, CAT), inflammatory (IL-1β), apoptotic (Bax, Bcl-2, caspase-3, 8, 9), and autophagy (Beclin-1, LC3) markers, NGAL, and histopathological changes in the kidney were measured. Colistin significantly increased serum creatinine, BUN, MDA, IL-1β, caspase-3,8,9, Bax, Beclin-1, LC3, and NGAL levels in kidney tissue. It also caused inflammation, focal necrosis of tubular epithelial cells, protein cast, and acute tubular necrosis. Furthermore, colistin decreased SOD, CAT, GSH, and Bcl-2 levels. TSC and vitamin E administration along with colistin restored most of the alterations induced by colistin. Overall, it could be concluded that colistin induces oxidative stress, inflammation, autophagy, and apoptosis, which can cause kidney injury. However, TSC can also be used as a therapeutic agent to reduce injuries caused by colistin.
