Abstract:
Objective:To explore the prevalence of passenger lymphocyte syndrome(PLS) after liver transplantation, minimize the result bias caused by previous multicenter confounding factors, make up for the lack of statistical analysis of PLS and provide reference for a diagnosis and treatment of PLS after liver transplantation.Methods:We reviewed liver transplants performed in our center from 2018 to 2019, searching for cases with minor ABO incompatibility or bidirectional ABO incompatibility. Diagnostic criteria for PLS: laboratory confirmation included biochemical identifiers of hemolysis, positivity of the direct antiglobul in test(DAT), donor attributed anti-recipient antibody in recipient's sera, and exclusion of other causes of decreased HGB(i.e. postoperative infection, acute rejection & surgical blood loss). A total of 666 liver transplants were performed. Among 52 patients with minor ABO incompatibility or bidirectional ABO incompatibility, 10 cases developed PLS(19.23%)and 42 cases did not(80.77%). Statistical comparisons between patients with and without PLS were performed using the chi-square test and Fisher's exact test.Results:There were no statistically significant differences in PLS group subjects in terms of sex, age, blood group, type of incompatibility, type of immunosuppressants and postoperative outcome. There was statistically significant correlation between postoperative blood transfusion and PLS( P< 0.05), and donor blood group B cohort demonstrated a higher risk of PLS than donor blood group A and O cohorts( P< 0.05). Conclusions:PLS is one of the causes for postoperative anemia in liver transplantation, and donor blood group B graft is a risk factor for PLS.
