%X Passenger lymphocyte syndrome (PLS) is a rare post solid organ transplantation complication, usually occurring after ABO- or Rh-mismatched transplantation. In general, PLS can lead to severe hemolytic anemia, but it is usually a self-limited disease. Most PLS cases start with a decreased hemoglobin (Hb) level and require donor type RBC transfusion as the only treatment.<BR>In our case, the allograft was given by an O-type Rh-D(+) donor and received by an A-type Rh-D(+) recipient. The PLS was developed on the post-operative day (POD) 10 with an increased indirect bilirubin (IDBIL) level as the first clinical symptom, while the Hb level did not significantly decrease. The PLS was diagnosed on POD 17 by a direct antiglobulin test (DAT) and a blood group test. The patient quickly became stable on POD 18 after a total of eight units of O-type RBC transfusion. Kidney function was uneventful in the entire PLS period.<BR>In ABO-mismatched kidney transplantation, an increased level of IDBIL should be considered as the first symptom of PLS even without an Hb decrease. The kidney function may be not affected by the PLS symptoms.
