Background Regional citrate anticoagulation (RCA) is being used increasingly in continuous renal replacement therapy (CRRT) as a safer alternative to heparin. However, complex metabolic control to avoid side effects have generated discrepancies about its introduction into everyday practice. We aimed to compare both anticoagulation techniques in terms of efficacy, safety and feasibility. Methods Observational retrospective study performed in 3 specialized ICUs in patients receiving CVVHDF with RCA between January 2013 and May 2016. Heparin-treated patients matched by age, sex and disease severity treated in the preceding year were selected as historic controls. Filter lifetime, number of filters used, haemorrhagic complications and metabolic complications were recorded. Results 54 patients (27 treated with RCA and 27 with heparin) were included in the study. Filter lifetimes in the first 72 hours were 55.1 ± 21.8 hours in the RCA group compared to 38.8 ± 24.8 hours in the heparin group, (p = 0.004). In addition, the number of filters used in the first 72 hours was significantly higher in the heparin group (2.4 ± 1.3 vs. 1.5 ± 0.7; p = 0.004). There was a trend toward a lower incidence of bleeding in the RCA group, with a significantly lower red blood cell transfusion rate (p = 0.027) in the citrate group. No clinically significant metabolic disturbances were observed in the RCA group. Regarding outcomes, there were no significant differences between groups. Conclusions These results suggest that the implementation of CVVHDF with RCA using concentrated citrate solutions prolongs filter lifetime, achieves a longer effective hemodiafiltration time and is a safe and feasible method.

Introduction: Regional citrate anticoagulation (RCA) is the recommended anticoagulation modality for continuous renal replacement therapy (CRRT). RCA was associated with a low rate of complications in randomized controlled trials. However, little is known about the type and rate of complications in real life. We sought to describe complications associated with RCA in comparison with those associated with heparin anticoagulation. Methods: In our institution, RCA has been the default anticoagulation modality for CRRT in all patients without contraindications since 2013. We have retrospectively reviewed all consecutive patients who received CRRT between January and December 2016 in our institution. For each CRRT session, we have assessed circuit duration, administered dose, as well as therapy-associated complications. Those parameters were compared according to whether the circuit was run in continuous veno-venous hemodialysis (CVVHD) mode with RCA or continuous veno-venous hemofiltration (CVVH) mode with heparin anticoagulation. Results: We analyzed 691 CRRT sessions in 121 patients. Of those 400 (57.9%) were performed in CVVHD-RCA mode and 291 (42.1%) in CVVH-Heparin Mode. Compared with ­CVVH-Heparin mode, CVVHD-RCA mode was associated with a longer circuit lifespan (median duration 54.9 interquartile range [IQR 44.6] vs. 15.3 h [IQR 22.4], p < 0.0001). It was associated with a higher rate of metabolic acidosis 77 (20.2%) vs. 18 (7.2%), (p < 0.0001), alkalosis 186 (48.7%) vs. 43 (17.1%), (p= 0.0001), and hypocalcemia 96 (25.07%) vs. 26 events (10.79%), p < 0.0001. However, the majority of these alterations were of benign or moderate severity. Only one possible citrate intoxication was observed. Conclusions: CVVHD-RCA was associated with a much longer circuit life but an increased rate of minor metabolic complications, in particular acid-base derangements. Some of these complications might have been prevented by therapy adaptation. Medical and nursing staff education is of major importance in the implementation of an RCA protocol.

Immobilization and prolonged bed rest are harmful to the skeleton, which suffers increased resorption, and contribute to reducing survival rates among patients in critical care units. We report a patient who presented hypercalcemia 10 days after continuous venovenous hemofiltration has ended. Investigative tests showed an increase of serum C-terminal telopeptide of type I collagen (CTx), with suppressed parathormone and calcitriol. Denosumab was administered with a significant response, decreasing ionized calcium and CTx levels. The calcium infusion rate during dialysis procedures, used for citrate anticoagulation compensation, has progressively decreased, suggesting that endogenous calcium was taking part in the citrate chelation. In this report, we highlight the challenges in early diagnosis of immobilization-induced hypercalcemia among patients who are on continuous renal replacement therapy undergoing citrate anticoagulation.
