Popis: Although the importance of reactive oxygen species (ROS) in the pathogenesis of various diseases is stressed, clinical significance of the markers reflecting DNA oxidation such as 8-hydroxy-2'-deoxyguanosine (8-OHdG) remains to be clarified.To examine clinical usefulness of 8-OHdG in healthy individuals in comparison with liver disease patients, urinary excretion of 8-OHdG was measured in 336 healthy individuals and 110 patients with liver disease.In healthy persons, the 8-OHdG excretion was increased in an age-dependent manner. It was positively correlated with cigarettes smoked a day and negatively correlated with body mass index (BMI) (P0.05, each). Age, smoking and BMI were independent predictors of urinary 8-OHdG excretion (P0.01, P0.01 and P0.05, respectively). In liver disease, the excretion of 8-OHdG was not changed, as compared with healthy individuals. However, the liver disease patients under the age of 40 had higher values of 8-OHdG than healthy persons. In addition, the urinary excretion of 8-OHdG was higher in patients with hepatitis C virus (HCV) infection than those with hepatitis B virus (HBV) infection.The results of the present study suggest that measurement of urinary 8-OHdG excretion is useful in assessing DNA oxidation caused by aging, smoking, body composition and liver disease.
