AZNAR BARBERO, Sonia et al. Citrate- versus acetate- based dialysate in patients in high-efficiency online hemodiafiltration: parameters to be studied. Enferm Nefrol [online]. 2014, vol.17, n.3, pp.192-197. ISSN 2255-3517.  http://dx.doi.org/10.4321/S2254-28842014000300005.

Introduction: Liquid dialysate with acetate (LDA) reported less biocompatible, generating oxidative stress and inflammation. Perceived benefits include its anti-inflammatory citrate buffer effect and antioxidant properties, anticoagulant power, chelating ionized calcium, and improves tolerance to the session. Objective: To compare nutritional and inflammatory parameters, dialysis efficiency, acid-base status, tolerance and calcium balance in on-line hemodiafiltration (OLHDF) using citrate dialysate (LDC) versus LDA. Methods: Prospective cross OLHDF population in 24 weeks. Begins 35 patients (33 finish), with 57.4 years, 55% male, 54.1 months of permanence. 79% carriers arteriovenous fistula. 2376 sessions are analyzed. The study has two phases. Variables: albumin, CRP, Beta 2 microglobulin (B2MCG), phase angle (PA), body cell mass (BCM), Kt, reinfusion volume, PTTA, hemostasis time, state cameras and dialyzer, pH, bicarbonate, calcium ion, sessions with hypotension and cramps. Statistical analysis SPSS 13.0. Hypothesis testing using T-Student and Wilcoxon W for quantitative variables. Chi-squared qualitative. Statistical significance p <0.05. Results: Significant differences (p <0.001) in albumin, CRP, and B2MCG. BCM (p = 0.001), AF (p = 0.002) and Kt (p <0.001) higher with LDC. Lower post-dialysis bicarbonate (p <0.001) with LDC. Calcium ion pre and post-dialysis (p = 0.007 and p <0.001 respectively) with lower LDC. Conclusion: Dialysis citrate shown in our series more biocompatible and less inflammation, improves nutritional parameters and analytical impedance and increases efficiency dialysis. Reduces post-dialysis bicarbonate. Both pre-and post-dialysis ionized calcium is lower, remaining stable.
