Delayed hemolytic transfusion reaction by anti-E alloantibody
Journal Title: Revista Información Científica - Year 2019, Vol 98, Issue 1
Abstract
We present the case of a 47-year-old woman, blood group O Rh D positive, G4P2A2, with no transfusion history, which required surgical intervention due to bleeding uterine fibroma. The pretransfusional tests were compatible, transfusing two concentrates of red blood cells, without presenting clinical manifestations; after seven days, he presented a haemolytic crisis, with abrupt fall in hematological parameters, cutaneous-mucosal pallor and icterus. The immunohematological studies were positive; the patient's blood sample was incompatible with a son, husband and the transfused red blood cells. Six months later, an anti-E alloantibody (128 dilutions) was identified in the patient. It is concluded that the patient was alloimmunized during her pregnancies with an anti-E antibody, where the blood transfusion was the antigenic stimulus causing the late hemolytic transfusion reaction.
