Objectives: Carbon tetrachloride (CCl4), employed in various industrial fields, can cause acute damage in renal tissues. This study investigated the therapeutic effect of the TNF-alpha inhibitor Infliximab on TGF-beta and apoptosis caused by acute kidney image induced by CCl4.
Methods: Twenty-four male Sprague-Dawley rats were assigned into control, CCl4, and CCl4+ Infliximab groups. The control group received an isotonic saline solution, and the CCl4 group 2 mL/kg CCl4 intraperitoneally (i.p). The CC(l)4+ Infliximab group was given 7 mg/kg Infliximab 24 hours after administration of 2 mL/kg CCl4. Kidney tissues were removed at the end of the experiment and subjected to histopathological and biochemical analysis.
Results: The application of CCl4 led to tubular necrosis, inflammation, vascular congestion, and increased Serum BUN and creatinine values. An increase in caspase-3 activity also occurred in the CCl4 group. However, Infliximab exhibited an ameliorating effect on kidney injury by causing a decrease in the number of apoptotic cells. Tissue ADA and TGF-beta values of the CCL4 group were significantly higher than the values of the control group (p = .001, p < .001 respectively) and CCL4+ Inf group (p = .004, p = .015, respectively).
Conclusions: This study shows that Infliximab ameliorates nephrotoxicity by reducing lipid peroxidation, oxidative stress, and apoptosis in acute kidney damage developing in association with CCI4 administration. These findings are promising in terms of the ameliorating role of TNF-alpha inhibitors in acute kidney injury.
