Interest in citrate-based dialysate (Cit-D) is growing due to its benefits, including anticoagulation and dialysis efficacy. However, research on safety and efficiency of Cit-D in high-volume hemodiafiltration (HDF) central concentrate delivery system (CCDS) is scarce. This study aimed to investigate the safety and efficacy of Cit-D when switching from acetate-based dialysate (Acet-D) in high-volume HDF CCDS. This is a retrospective analysis of 28 patients who underwent post-dilution online HDF CCDS, who switched from Acet-D to Cit-D. The study period was divided into 3 periods for analysis: 12 weeks using Acet-D (AD period), the first 12 weeks using Cit-D (CD-1 period), and the second 12 weeks using Cit-D (CD-2 period). We collected the laboratory, dialysis, and safety parameters in each period from electrical medical records. After switching from Acet-D to Cit-D, heparin dosage decreased by 17%, whereas the incidence of complications did not increase. Kt/V and urea reduction ratio increased by 4.6% and 2.1%, respectively. Pre-dialysis beta-microglobulin concentration decreased after using Cit-D. The corrected calcium levels decreased in the CD-1 period compared to the AD period, but in CD-2, they subsequently increased to levels similar to those observed during the AD period. Symptomatic hypocalcemia did not occur, and there was no significant difference in the incidence of hyperparathyroidism. Endotoxin levels and the bacterial culture of ultrapure dialysate were unremarkable throughout all periods. These results might suggest that Cit-D could potentially offer advantages over Acet-D, such as reducing the heparin dose and increasing dialysis efficiency, in patients undergoing high-volume HDF using CCDS.
