Perioperative Fresh Red Blood Cell Transfusion May Negatively Affect Recipient Survival After Liver Transplantation.

Conference Paper

OBJECTIVE: The aim of this study is to evaluate the association between fresh red blood cell (RBC) transfusion and recipient survival after liver transplantation. BACKGROUND: Fresh RBC products contain many viable leukocytes. Allogeneic leukocytes are responsible for adverse transfusion reactions in the immunocompromised host. METHODS: Among 343 liver transplant recipients who underwent perioperative RBC transfusion, 91 of 226 who did not receive fresh RBCs were matched with 91 of 117 who received fresh RBCs with 1:1 matching ratio using the propensity score based on the amount of transfused blood products and others. Survival analysis was performed using the Cox model. RESULTS: All transfused 3230 RBCs were leukoreduced and irradiated. Before matching, recipients in fresh RBC group received 3 U (2-6 U) of fresh RBCs. After a median follow-up of 60 months, 60 of 343 recipients (17.5%) died. Survival probability at 1/2/5 years after transplantation was 94.7%/92.0%/85.8% for nonfresh RBC group and 82.9%/76.0%/72.0% for fresh RBC group [death hazard ratio (HR) = 2.37 (1.43-3.94), P = 0.001]. In multivariable analysis, fresh RBC transfusion was significantly associated with increased death risk [HR = 2.33 (1.35-4.01), P = 0.002]. After matching, recipients in fresh RBC group received 3 U (2-5 U) of fresh RBCs. After a median follow-up of 56 months, 35 of 182 recipients (19.2%) died. Survival probability at 1/2/5 years was 95.6%/93.2%/86.0% for nonfresh RBC group and 85.7%/78.0%/73.0% for fresh RBC group [HR = 2.23 (1.43-3.94), P = 0.028]. Multivariable analysis confirmed a significance of fresh RBC transfusion [HR = 3.20 (1.51-6.78), P = 0.002]. CONCLUSION: Our findings suggest a potential negative impact of fresh RBC transfusion on the survival of patients undergoing liver transplantation.
