Direct oral anticoagulant agents attenuate temporary aortic occlusion-induced renal oxidative and inflammatory responses in rats

Background: This study aims to investigate the effects of different direct oral anticoagulants on experimental renal injury induced by temporary infrarenal aortic occlusion. Methods: A total of 35 male Wistar rats (250 to 350 g) were randomly allocated to any of the five groups: sham, ischemia-reperfusion, rivaroxaban, dabigatran, and apixaban groups. Sham group underwent median laparotomy. Ischemia-reperfusion group was given saline gavage for one week. Animals in the other groups received rivaroxaban (3 mg/kg), dabigatran (15 mg/kg), or apixaban (10 mg/kg) daily once for one week via oral gavage. The infrarenal abdominal aorta was clamped for 60 min, and reperfusion was maintained for 120 min in the ischemia-reperfusion, rivaroxaban, dabigatran, and apixaban groups. At the end of reperfusion, kidneys were harvested for biochemical and histopathological analysis. Results: Renal total antioxidant capacity was reduced, and total oxidant status, interleukin-1 beta, and tumor necrosis factor-alpha were elevated in the ischemia-reperfusion group, compared to the sham group (p
