The effect of different doses and types of intravenous iron on oxidative stress and inflammation in hemodialysis patients

Background: Although intravenous iron (IVI) is thought to have potential inflammatory and atherogenic effects, there are not enough studies comparing these effects in chronic hemodialysis (HD) patients. In this study, different doses and types of IVI were examined for effects on inflammation and oxidative stress. Methods: Chronic HD patients (n=101) were grouped into those not receiving IVI (group 1, n=29), those getting intermittent iron sucrose (group 2, n=25), those receiving intermittent iron dextran (group 3, n=24) and those getting a once monthly total dose of iron dextran (group 4, n=23). Malondialdehyde (MDA), advanced oxidation protein product (AOPP), C-reactive protein (CRP) and TNF-alpha levels were measured on days 0, 2, 7 and 28. Results: Groups were similar regarding age, sex, hemoglobin, iron indices and total amount of IVI given monthly. Although MDA levels at days 7 and 28, AOPP levels at days 0 and 28, CRP levels at day 28 and TNF-alpha level at day 7 were higher than at other days, there were no significant differences between the IVI groups on statistical analysis. Conclusion: The different types and doses (intermittent or once monthly total dose) of IVI treatments are well tolerated without negative effects on the markers of lipid and protein oxidation and inflammatory indices in chronic HD patients.
