Comparison of Citrate and Heparin Anticoagulation During Postdilution Hemodiafiltration

Sponsor: University Medical Centre Ljubljana

Summary

This randomized crossover clinical trial will compare regional citrate anticoagulation (RCA) and standard heparin anticoagulation (HA) during postdilution hemodiafiltration (HDF) in chronic dialysis patients with end-stage kidney disease. The primary aim of the study is to evaluate biocompatibility during HDF by measuring markers of complement activation (C3a), platelet activation (PF4), and coagulation activation (thrombin-antithrombin complex, TAT). Secondary aims include comparison of solute removal efficiency, including beta-2 microglobulin, phosphate, and urea removal, as well as assessment of citrate, calcium, and magnesium kinetics during citrate anticoagulation. Twenty adult chronic dialysis patients will undergo two study HDF procedures in randomized order: one procedure using heparin anticoagulation and one procedure using regional citrate anticoagulation with a one-week interval between procedures. The study aims to improve understanding of the effects of anticoagulation methods on hemodiafiltration biocompatibility and dialysis efficiency and may contribute to optimization of citrate anticoagulation protocols in chronic hemodiafiltration patients.
