Abstract

BACKGROUND
The objective of this study was to compare the impact of citrate dialysate (CD) and standard acetate dialysate (AD) in hemodialysis by central delivery system (CDS) on heparin demand, and clinical parameters.
METHODS
We retrospectively evaluated 75 patients on maintenance hemodialysis with CDS. Patients underwent hemodialysis with AD over a six-month period (AD period), followed by another six-month period using CD (CD period). Various parameters including mean heparin dosage, high sensitivity C-reactive protein (hsCRP), calcium-phosphate product (CaxP), intact parathyroid hormone (iPTH), and urea reduction ratio (URR) were collated at the end of each period.
RESULTS
Patients were 60.5 ± 14.7 years old, of whom 62.7% were male. Patients required less heparin when receiving CD (AD period: 1,129 ± 1,033 IU/session vs. CD period: 787 ± 755 IU/session, P < 0.001). After the CD period (Δ(CD)), pre-dialysis total COâ‚‚ increased to 1.21 ± 2.80 mmol/L, compared to −2.44 ± 2.96 mmol/L (P < 0.001) after the AD period (Δ(AD)). After the CD period, concentrations of iPTH (Δ(AD): 73.04 ± 216.34 pg/mL vs. Δ(CD): −106.66 ± 251.79 pg/mL, P < 0.001) and CaxP (Δ(AD): 4.32 ± 16.63 mg²/dL² vs. Δ(CD): −4.67 ± 15.27 mg²/dL², P = 0.015) decreased. While hsCRP levels decreased after the CD period (Δ(AD): 0.07 ± 4.09 mg/L vs. Δ(CD): −0.75 ± 4.56 mg/L, P = 0.705), the change was statistically insignificant. URR remained above clinical guideline of 65% after both periods (Δ(AD): 72.33 ± 6.92% vs. Δ(CD) period: 69.20 ± 4.49%, P = 0.046).
CONCLUSION
Our study confirmed that the use of CD in CDS required lower heparin doses compared to the use of AD. The use of CD also provided a more stable acid-base status.
