HEMOLYSIS DUE TO THE SIMULTANEOUS OCCURRENCE OF PASSENGER LYMPHOCYTE SYNDROME AND A DELAYED HEMOLYTIC TRANSFUSION REACTION IN A LIVER-TRANSPLANT PATIENT

Hemolysis due to donor-derived antibodies produced by ''passenger'' B lymphocytes, called passenger lymphocyte syndrome, has been described in ABO-unmatched solid organ and bone marrow transplant recipients. De layed hemolytic transfusion reactions occur within a similar time fram e and have similar clinical and serologic findings. To our knowledge, we report the first case of hemolysis due to the simultaneous occurren ce of passenger lymphocyte syndrome (donor-derived anti-A) and a delay ed hemolytic transfusion reaction (recipient-produced anti-E) in a liv er transplant patient.
