AI Article Synopsis
- This study focused on whether zinc supplementation, specifically using zinc acetate hydrate, could help improve renal anemia in patients on hemodialysis with low zinc levels.
- It involved 21 patients over 6 months, measuring changes in zinc levels and erythropoietin resistance (ERI) to assess the impact of the supplementation.
- Results showed that zinc levels increased significantly, while the need for erythropoiesis-stimulating agents and ERI decreased, indicating that correcting low zinc levels may benefit renal anemia management.
Article Abstract
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 < 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; < 0.01); the ESA dose significantly decreased, from 0-12,000 IU/week (5630 ± 3351 IU/week) to 0-9000 IU/week (4428 ± 2779; = 0.04); and ERI significantly decreased, from 0.0-18.2 (8.1 ± 5.1) to 0.0-16.0 (6.3 ± 4.3; = 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.

A novel phthalocyanine-based hybrid nanofilm is for the first time successfully applied as an oxidative platform for surface enhanced Raman spectroscopy (SERS) sensing to fine-resolve Raman-inactive compounds. The hybrid is formed by self-assembly of zinc(II) 2,3,9,10,16,17,23,24-Octa[(3',5'-dicarboxy)-phenoxy]phthalocyaninate (ZnPc*) with the solid-supported monolayer of graphene oxide (GO) mediated by zinc acetate metal cluster. Atomic force microscopy, UV-vis and fluorescence spectroscopies confirm that this simple coordination motive in combination with molecular structure of ZnPc* prevents contact quenching of the light-excited triplet state through aromatic stacking with GO particles.

Objective: This study evaluated the efficacy and safety of NPC-25, zinc histidine hydrate, in patients with hypozincemia. This randomized multicenter active-controlled open-label trial aimed to verify the non-inferiority of NPC-25 to NOBELZIN™, zinc acetate dihydrate.
Methods: Participants whose serum zinc concentrations were <70 μg/dL at two points within 8 weeks before the start of treatment were randomized 1:1 into the NPC-25 (active drug) administration group and the NOBELZIN™ (control drug) administration group, using dynamic allocation.

In modern times, achieving precise drug delivery through a safe and stable carrier remains a significant challenge. In this study, we synthesized a novel ligand based on a guanazole Schiff base and subsequently developed new metal-organic framework (MOF) named UWO-1 through a reaction involving zinc acetate. At the same time, curcumin (CUR) was loaded onto the newly synthesized UWO-1.
