BACKGROUND Hemodialysis patients are common to have renal anemia in the nephrology practice. For the renal anemia, the high-dose iron from the intravenous route is an important treatment option. We can understand the treatment effects and cardiovascular events of high-dose intravenous iron reviewing the randomized clinical trials. METHODS We compared the high-dose and low-dose iron treatments to find if the high-dose intravenous iron can influence the hematological parameters more significantly than the low-dose iron. The cardiovascular events were also analyzed for the high-dose iron treatment. Six studies with a total of 2422 renal anemia patients under hemodialysis were enrolled. We focused the outcomes of hemoglobin, transferrin saturation percentage, ferritin, erythropoietin dose, and cardiovascular events. RESULTS The high-dose intravenous iron might be associated with a greater number of ferritin, transferrin saturation percentage, and hemoglobin. In addition, the erythropoietin dose was less needed to maintain the ideal hemoglobin range in the high-dose intravenous iron group. CONCLUSIONS In current meta-analysis, the high-dose intravenous iron might show the superior effects on the ferritin, transferrin saturation percentage, and hemoglobin levels and needed dose of erythropoietin when compared to low-dose iron treatment.
