Overt immediate hemolytic transfusion reaction attributable to anti-Wra

Hemolytic transfusion reaction due to anti-IH.

BACKGROUND Anti-IH is usually a clinically insignificant antibody that may complicate a serologic workup. However, it can occasionally cause hemolysis. We report a rare case of acute hemolysis caused by anti-IH. CASE REPORT A 60-year-old man with a long history of chronic myelomonocytic leukemia and anemia, blood group A, D+ was found to have an unidentified antibody on serologic workup. He r...

Hemolytic transfusion reaction due to anti-A.

Delayed hemolytic transfusion reaction due to anti-Jk(a).

BACKGROUND Kidd antibodies are very heterogeneous and difficult to detect. They have been frequently implicated in delayed hemolytic transfusion reactions (DHTRs). CASE REPORT A 64 year old female (6 pregnancies, 2 deliveries, 4 abortions) with none red cell (RBC) transfusions in the history was admitted to hospital due to pneumonia and severe anemia. On admittance hemoglobin (Hb) level was 6...

A case of acute hemolytic transfusion reaction due to anti-Dia antibody -A case report-

Many medical institutions in Korea have recently been performing an antibody screening test as one of the essential elements of a pre-transfusion test. The Di(a) antigen is well known as one of the antigens with low incidence among Caucasians; however, it has been discovered with a relatively higher incidence among Mongoloid populations. The frequency of the Di(a) antigen among the Korean popul...

Acute hemolytic transfusion reactions due to multiple alloantibodies including anti-E, anti-c and anti-Jkb.

We report a case of two consecutive episodes of acute hemolytic transfusion reactions (HTRs) due to multiple alloantibodies in a 34-yr-old man who suffered from avascular necrosis of left femoral head. He received five units of packed red blood cells (RBCs) during surgery. Then the transfusion of packed RBCs was required nine days after the surgery because of the unexplained drop in hemoglobin ...
