Renal transplantation (RT), has been considered the best therapeutic option for end stage renal disease (ESRD). Objective. To determine the effect of RT on the evolution of oxidative DNA status. Methods. Prospective cohort ( receptors of RT); genotoxic damage, 8-hydroxy-2′-deoxyguanosine (8-OHdG), and DNA repair enzyme, human 8-oxoguanine-DNA-N- glycosylase-1 (hOGG1); and antioxidants, superoxide dismutase (SOD) and glutathione peroxidase (GPx), were evaluated. Results. Before RT, 8-OHdG were significantly elevated ( versus 4.73 ± 0.34 ng/mL) compared to healthy controls (), with normalization after 6 months of  ng/mL (). The same phenomenon was observed with hOGG1 enzyme before RT with 2.14 ± 0.36 ng/mL () and decreased significantly at the end of the study to 1.20 ng/mL () but was higher than controls, 0.51 ± 0.07 ng/mL (). Antioxidant SOD was elevated at 24.09 ± 1.6 IU/mL versus healthy controls () before RT; however, 6 months after RT it decreased significantly to 16.9 ± 1.6 IU/mL (), without achieving the levels of healthy controls (). The GPx, before RT, was significantly diminished with 24.09 ± 1.6 IU/mL versus healthy controls (39.0 ± 1.58) (), while, in the final results, levels increased significantly to 30.38 ± 3.16 IU/mL (). Discussion. Patients with ESRD have important oxidative damage before RT. The RT significantly reduces oxidative damage and partially regulates the antioxidant enzymes (SOD and GPx).
