Background: Iron support is an important component of treatment of anemia in hemodialysis (HD) patients. However, there are concerns about endovenous (EV) iron therapy that may cause endothelial dysfunction (ED) by increasing oxidative stress (OS) and lead to cardiovascular events. In this study, we aimed to evaluate the effects of high and repeated doses of EV iron sucrose on endothelial functions in acute and subacute phases. Methods: We included 15 HD patients to our study. There were 16 patients with iron deficiency but normal kidney functions in control group. We also evaluated endothelium-dependent vasodilatation (EDV) and nitroglycerin-induced vasodilatation (NIV) from the brachial artery by ultrasonography at the beginning of the study, and then 200 mg EV iron sucrose was given initially to both groups for 1 h in 250 cc 0.9% saline and 4 h after the end of the infusion (acute phase) sonographic vasodilatation parameters were measured from brachial artery. These measurements and laboratory tests were repeated 1 week after the end of a total 1000 mg EV iron sucrose replacement (200 mg/week). Results: There was a statistically significant increase in hemoglobin and ferritin levels after the EV iron sucrose therapy in both control and patient groups. EDV values in the HD group were significantly lower than that in the control group before therapy (6.25% vs. 10.53%, p < 0.05). EV iron sucrose therapy did not alter EDV and NIV values at the 4th hour and 6th week in both control and patient groups. Conclusion: According to our study, compared with the control group with normal kidney functions, HD patients had impaired endothelial functions. However, in HD patients, high and repeated doses of EV iron sucrose do not have deleterious effects on endothelial functions at acute and subacute phases and can be used safely in that patient group.
