title: [The relationship between viral load and malondialdehyde and antioxidant enzymes in patients with hepatitis C virus infection].
abstract: Oxidative stress is known to participate in the pathogenesis of HCV infection. The aim of this study was to investigate the relationship between antioxidant defence state, malondialdehyde (MDA) and viral load in patients with hepatitis C virus (HCV) infection. Fifty patients who were positive for serological and molecular markers of HCV infection, and 40 healthy volunteers as control group were included in the study. The patients were classified according to their viral loads, and the catalase, superoxide dismutase (SOD) and glutathione peroxidase (GP) activities of erythrocytes and MDA in sera of all groups were measured. These substances were detected by using the methods described by Aebi, Woolliams et al, Paglia and Valentine, Draper and Hadley, respectively. As a result, decrease in SOD and GP levels and increase in MDA and catalase levels have been detected in HCV infected patients when compared with healthy controls, and these differences were statistically significant (p<0.05, t=19.3),except for catalase. However, there were no statistically significant difference among groups classified according to viral load (p>0.05, t=1.6). Although our data in HCV infected patients demonstrate a significant decrease in antioxidant enzyme levels and a significant increase in MDA levels, a marker of oxidative stress, it could not possible to make a correlation between these differences and the viral loads of patients.
