Özet

Ischemia-reperfusion-induced (I/R) renal damage is a pathogenic process that starts with ischemia, then progresses through oxidative stress and inflammation. Tocilizumab (TCZ), a recombinant human monoclonal antibody produced against the IL-6 receptor, will be tested against renal I/R injury. TCZ is known to lower the levels of proinflammatory cytokines and oxidant mediators while raising the amounts of antioxidant molecules. Our purpose is to evaluate the biochemical and histological effects of TCZ against I/R-induced oxido-inflammatory kidney damage and dysfunction in rats. Animals were divided into 3 groups as renal I/R (RIR), I/R+ TCZ (IRT), and healthy group (HG). TCZ was administered at a dose of 8 mg/kg to the IRT group (n=6) of the animals, and distilled water as a solvent was administered intraperitoneally (ip) to the RIR (n=6) and HG (n=6) groups. Then, two hours of ischemia and six hours of reperfusion were applied to the left kidneys of IRT and RIR animals. TCZ significantly inhibited the increase in the levels of malondialdehyde (MDA), nuclear kappa B (NF-κB), tumour necrosis factor alpha (TNF-α), interleukin 1-β (IL-1β), IL-6, creatinine (Cr) and blood urea nitrogen (BUN) and decrease in total glutathione (tGSH) with I/R in renal tissue. TCZ also attenuated severe histopathological damage due to I/R in renal tissue. TCZ protected renal tissue from I/R-induced oxidative and inflammatory damage. These results indicate that TCZ may be useful in the treatment of renal I/R injury.
