    Abstract:
    BACKGROUND: Adalimumab (ADA) is a potent inhibitor of tumor necrosis factor (TNF-α). ADA treatment suppresses proinflammatory cytokines, leading to a decrease or inhibition of the inflammatory process. OBJECTIVES: The aim of this study was to investigate the possible protective effects of ADA on oxidative stress and cellular damage on rat kidney tissue after ischemia/reperfusion (I/R). MATERIAL AND METHODS: A total of 30 male Wistar albino rats were divided into three groups: control, I/R, and I/R plus ADA (I/R + ADA); each group comprised 10 animals. The control group underwent laparotomy without I/R injury. After undergoing laparotomy, I/R groups underwent two hours of infrarenal abdominal aortic cross ligation, which was followed by two hours of reperfusion. ADA (50 mg/kg) was administered as a single dose, intraperitoneally, to the I/R + ADA group, 5 days before I/R. RESULTS: The I/R group's TNF-α (1150.9 ± 145.6 pg/mg protein), IL-1β (287.0 ± 32.4 pg/mg protein) and IL-6 (1085.6 ± 56.7 pg/mg protein) levels were significantly higher than those of the control (916.1 ± 88.7 pg/mg protein, p = 0.003; 187.5 ± 37.2 pg/mg protein, p < 0.001; 881.4 ± 57.1 pg/mg protein, p < 0.001, respectively) and I/R + ADA groups (864.2 ± 169.4 pg/mg protein, p = 0.003; 241.4 ± 33.4 pg/mg protein, p = 0.010; 987.7 ± 66.5 pg/mg protein, p = 0.004, respectively). To date, a few histopathological changes have been reported regarding renal I/R injury in rats due to ADA treatment whereas I/R caused severe histopathological injury to kidney tissue. CONCLUSIONS: ADA treatment significantly attenuated the severity of kidney I/R injury, inhibiting I/R-induced oxidative stress and renal damage. Because of its anti-inflammatory and antioxidant effects, ADA pretreatment may have protective effects on experimental kidney injury.
