Graft-versus-host antibody reaction causing a delayed hemolytic anemia after blood transfusion [letter]

Graft-versus-host antibody reaction causing a delayed hemolytic anemia after blood transfusion.

Delayed hemolytic transfusion reaction presenting as a painful crisis in a patient with sickle cell anemia.

CONTEXT Patients with sickle cell anemia (SCA) are frequently transfused with red blood cells (RBC). Recently we reported that the calculated risk of RBC alloimmunization per transfussed unit in Brazilian patients with SCA is 1.15%. We describe a delayed hemolytic transfusion reaction (DHTR) presenting as a painful crisis in a patient with SCA. CASE REPORT A 35-year-old Brazilian female with ...

Cerebrovascular accident during a delayed hemolytic transfusion reaction in a patient with sickle cell anemia.

A 28-year-old woman with sickle cell anemia suffered a left hemispheric cerebrovascular accident associated with severe right-sided weakness during a delayed hemolytic transfusion reaction owing to anti-rh' (C) and anti-S. The anti-rh' (C) had been identified four years earlier at a different hospital but neither the patient, her family, nor any member of the staff of the hospital where she was...

Erythropoiesis after exchange transfusion in hemolytic anemia.

I HE CONTROL of red cell productiomi is undoubtedly geared toward maintaining the red cell mass at a functionally optimal size. Since the primary function of the red cell mass is to transport oxygen to the tissues, it is generally assumed that the control is triggered by the tissue tension of oxygen. Recent studies indicate that the oxygen tension in one target area, the kidney, is inversely pr...

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...
