Abstract: Objective The aim of this study was to investigate the safety and clinical efficacy of double filtration plasmapheresis (DFPP) in ABO-incompatible kidney transplantation (ABOi-KT). Methods 80 patients with renal failure were encountered in our hospital between January 2020 and December 2021, all received ABOi-KT, and underwent DFPP in 62 cases, and underwent plasma exchange (PE) in 18 cases for removal of blood type antibodies before KT. Serum A/B IgM and IgG antibodies were determined by column agglutination technology (CAT). Result In DFPP group, serum antibody titers of all blood types decreased significantly after removal, except for serum IgM anti-B antibody; in the PE group, only serum IgG anti-A showed remarkably decreased; there was no significant difference as respect to overall removal of serum antibodies between the two methods; there were no removal-related adverse reactions in the perioperative period in either group; three patients (4.8%) in the DFPP group experienced dysfunctions of the transplanted kidney, and four patients (6.4%) died. Conclusion DFPP exhibits efficacious and safe for removal blood type antibodies before ABOi-KT, which warrants further clinical investigation.
