Overview

Introduction and Aims: This study examined whether zinc supplementation with zinc acetate hydrate improved renal anemia with hypozincemia in patients undergoing hemodialysis. Methods: The study participants included 21 patients undergoing hemodialysis who presented with a serum zinc level < 60 mg/dL and who were administered zinc acetate hydrate at 50 mg (reduced to 25 mg, as appropriate) for 6 months. Patients with a hemorrhagic lesion, acute-phase disease (pneumonia or cardiac failure), or hematologic disease and those whose treatment was switched from peritoneal dialysis to hemodialysis were excluded. The changes in the erythropoietin resistance index (ERI) before and after zinc acetate hydrate administration were examined. ERI was defined as the dose (IU) of erythropoiesis-stimulating agent (ESA)/week/body weight (kg)/hemoglobin content (g/dL). The differences between the two groups were analyzed using the Wilcoxon signed rank sum test, and p < 0.05 was considered statistically significant. Results: The study participants included 19 men and 2 women aged 41–95 years (mean ± standard deviation (SD): 67.1 ± 13.6). The changes in the values of parameters measured before and after zinc acetate hydrate administration were as follows: Blood Hb did not change significantly, from 10.0–13.6 g/dL (11.5 ± 1.0 g/dL) to 10.2–12.4 g/dL (11.4 ± 0.7 g/dL); serum zinc concentration significantly increased, from 33.0–59.0 mg/dL μg/dL (52.4 ± 7.6 mg/dL μg/dL) to 57.0–124.0 mg/dL μg/dL (84.1 ± 16.3 mg/dL μg/dL; p < 0.01); the ESA dose significantly decreased, from 0–12,000 IU/week (5630 ± 3351 IU/week) to 0–9000 IU/week (4428 ± 2779; p = 0.04); and ERI significantly decreased, from 0.0–18.2 (8.1 ± 5.1) to 0.0–16.0 (6.3 ± 4.3; p = 0.04). Conclusions: Zinc supplementation increased the serum zinc concentration and significantly reduced the ESA dose and ERI, suggesting that a correction of hypozincemia contributes to lessening renal anemia in these patients.
