Apheresis therapy is used to remove pathogenic antibodies within the recipient blood during ABO-incompatible living related renal transplantation (LRRT). Factor XIII (FXIII) is a coagulating factor. Its deficiency reportedly engenders perioperative bleeding. This study compared apheresis modalities from the perspective of the FXIII level. Cases 1-3 were treated only with double-filtration plasmapheresis (DFPP) without (case 1) or with (cases 2 and 3) fresh frozen plasma (FFP) supplementation. Cases 4 and 5 were treated with simple plasma exchange (PEx) with FFP supplementation for the last session. Cases 1-3 showed a marked (case 1, 8.6%) or moderate (case 2, 26.2%; case 3, 28.4%) decrease in FXIII on the day before the procedure after the last apheresis session, although cases 4 (81.9%) and 5 (66.2%) did not. Case 1 experienced perioperative bleeding. The last session is usually performed the day before the surgical procedure. Therefore, FXIII elimination by DFPP might cause bleeding complications because of its slow recovery. The fact warrants that the last apheresis modality during the course might be PEx from the viewpoint of FXIII depletion.
