ABSTRACT

BACKGROUND: Intravenous (IV) iron supplementation is widely used in hemodialysis (HD) patients to treat their periodic losses. However, the ideal dose and frequency is unknown. The goal of the study is to see if a 20 mg dose of iron IV at the end of each session of HD as iron maintenance is better than the iron prior therapy. We analyze the erythropoiesis activity (EA) and functional iron (FI) after four weeks of treatment. METHODS: In 36 patients, we measure reticulocyte count and content of hemoglobin reticulocyte (CHr) as EA and FI markers, respectively, before and after the treatment. Before the study, 23 patients received another different therapy with IV iron as maintenance therapy. RESULTS: Reticulocyte count: 49.7 ± 23.8 × 10(3) before and 47.2 ± 17.2 × 10(3) after the treatment (p= 0.51). The CHr: 34.8 ± 3.7 pg and 34.4 ± 3.5 pg, respectively, (p= 0.35), showing an excellent correlation with the other FI markers (serum iron r = 0.6; p = 0.001; saturation transferrin r = 0.49; p = 0.004); that is not shown with the serum ferritin (r = 0.23; p = 0.192) or the hepcidin levels (r = 0.22; p = 0.251). There was not a correlation between the C-Reactive Protein, reticulocyte count, and CHr. The 13 patients who did not receive the iron prior to the study showed high FI levels, but not an increased of the serum ferritin or the serum hepcidin levels. CONCLUSIONS: The administration of a small quantity of iron at the end of every HD session keeps the EA and the FI levels and allows reducing the iron overload administered and/or decreasing the iron stores markers in some patients.
