چکیده

Background: natalizumab is a monoclonal antibody used to treat multiple sclerosis. this study sought to determine whether the protective action of natalizumab involved a reduction in oxidative damage. methods: twenty-two multiple sclerosis patients fulfilling the revised mcdonald criteria were assigned to treatment with 300 mg natalizumab intravenously once monthly (infusion every 4 weeks) in accordance with spanish guidelines. carbonylated proteins,8-hydroxy-2'-deoxyguanosine,total glutathione,reduced glutathione,superoxide dismutase,glutathione peroxidase,and myeloperoxidase levels were measured at baseline and after 14 months' treatment,and the antioxidant gap was calculated. results: natalizumab prompted a drop in oxidative-damage biomarker levels,together with a reduction both in myeloperoxidase levels and in the myeloperoxidase/neutrophil granulocyte ratio. interestingly,natalizumab induced nuclear translocation of nrf2 and a fall in serum vascular cell adhesion molecule-1 levels. conclusion: these findings suggest that natalizumab has a beneficial effect on oxidative damage found in ms patients. copyright © 2013 by institute of pharmacology polish academy of sciences.
