This study reports the use of heparin as an alternative anticoagulant for immunoadsorption (IA) in the preparation of ABO blood group-incompatible living donor kidney transplantation (ABOi LDKT). Results showed that IA with heparin was safe and effective, with no major bleeding or significant complications observed. Graft function, graft survival, and overall survival did not significantly differ from standard anticoagulation or ABO compatible recipients.
Introduction: Immunoadsorption (IA) of isohemagglutinins is an often-crucial procedure in preparation of major ABO blood group-incompatible living donor kidney transplantation (ABOi LDKT). Standard citrate-based anticoagulation during the procedure has potential disadvantages for distinct patient groups. In this study, we report our experience with an alternative anticoagulation scheme using heparin during IA for selected patients. Methods: We conducted a retrospective analysis of all patients who underwent IA with heparin anticoagulation between February 2013 and December 2019 at our institution with focus on the safety and efficacy of the adapted procedure. For further validation, we compared graft function, graft survival, and overall survival with those of all recipients of living donor kidney transplants with or without pretransplant desensitizing apheresis for ABO antibodies at our institution during the same period. Results: In thirteen consecutive patients prepared for ABOi LDKT with IA with heparin anticoagulation, no major bleeding or other significant complications were observed. All patients achieved sufficient isohemagglutinin titer reduction to proceed to transplant surgery. Graft function, graft survival, and overall survival did not significantly differ from patients treated with standard anticoagulation for IA or ABO compatible recipients of living donor kidneys. Conclusion: IA with heparin in preparation of ABOi LDKT is safe and feasible for selected patients after internal validation.
