High Rate of Passenger Lymphocyte Syndrome after ABO Minor Incompatible Lung Transplantation.

Passenger lymphocyte syndrome (PLS) may complicate minor ABO mismatched lung transplantation (LuTX) via donor-derived red cell antibody-induced hemolysis. To ascertain the incidence and specificity of PLS-relevant antibodies among the study population as well as the dynamics of hemolysis parameters and the transfusion requirement of patients with or without PLS. In this cohort study, 1,011 patients who received LuTX between January 2010 and June 2019 were studied retrospectively.
