Abstract Background: Stroke is the second cause of death and disability in the world, and oxidative stress which could be considered as a prognostic factor in patients for prevention, follow up and determination of stroke’s severity has a conceivable role in neural damage. Objectives: The aim of our study was to explain the association between oxidant/antioxidant imbalance as a prognostic factor in patients with stroke. Patients and Methods: Pro-oxidant-antioxidant balance (PAB), advanced oxidized protein products (AOPP) and protein carbonyl were measured in patients with ischemic stroke and hemorrhagic stroke as well as healthy group. Sera were collected from 18 is- chemic and 23 hemorrhagic stroke patients, and 34 healthy volunteers. The PAB assay, routine biochemical parameters, lipid proﬁle and total protein concentration were assessed in patients and healthy group. Results: The level of AOPP (P < 0.007), protein carbonyl (P < 0.001) and PAB (P < 0.01) were signiﬁcantly higher in stroke patients than the healthy group. Conclusions: There are increased level of protein carbonyl, AOPP and PAB in patients with stroke. Measuring these factors may be beneﬁcial as prognostic factors in treatment and follow up of the patients with both hemorrhagic and ischemic strokes. More investigations withmore cases and longer follow up are needed to approve that these factors play an important role in prognosis of stroke.
