Oxidative stress possibly helps to promote the progression and complication of chronic renal failure (CRF). Hemodialysis (HD) may aggravate oxidative stress. In addition long time of treatment may intensify the oxidative stress. Thus, the aim of this study was to evaluate the effect of prolonged HD treatment under parameters of the oxidative stress. Methods: Plasmatic thiobarbituric acid reactive substances (TBARS), plasmatic malondialdehyde (MDA), blood delta-aminolevulinate dehydratase (ALA-D) activity, ALA-D reactivation index, and erythrocytic reduced glutathione (GSH) were measured into two different groups of HD patients: recent treatment (n = 36; HD duration: 17.7 +/- 1.71 months), and long time of treatment (n = 26; HD duration: 82.2 +/- 6.32 months), and in a control group (n = 40). Results: Plasmatic TBARS and MDA levels were both elevated in HD patients. However, only MDA levels had positive correlation with time of HD treatment. Blood ALA-D activity was decreased in HD patients. The ALA-D reactivation index showed increase in HD patients, and it had correlation with the time of HD treatment. Erythrocytic GSH levels were increased in HD patients. Conclusions: Our results indicated that MDA levels and ALA-D reactivation index may be the better biomarkers to evaluate chronic oxidative stress in comparison with others markers analyzed in this study.
