Hemolytic transfusion reaction attributable to anti-Dia  

In situations when a patient's antibody detection test is negative, many institutions have moved from an indirect antiglobulin test (IAT) crossmatch to an electronic crossmatch system. Here we report a case of an acute hemolytic transfusion reaction attributable to anti-Dia in a patient with a negative antibody detection test. A 22-year-old female patient with a diagnosis of β thalassemia and sickle cell anemia commenced a routine exchange transfusion of 5 units of red blood cells

Acute hemolytic transfusion reaction attributed to anti-Ata

Anti-Ata is a rare alloantibody that can be clinically significant. We report a case of a woman who, after emergency-released uncrossmatched red blood cell transfusion, experienced an acute hemolytic transfusion reaction attributed to anti-Ata. The case presented herein highlights the importance of recognizing that anti-Ata may indeed cause acute hemolytic reactions.

Acute hemolytic transfusion reaction secondary to anti-Fy3

A hemolytic transfusion reaction due to anti-Fy3 is reported in an African American patient with no history of sickle cell disease. This 82-year-old African American woman received two units of RBCs for anemia (Hb 7g/dL) on admission for a left hip fracture. On hospital Day 7, the patient underwent left hip endoprosthesis surgery; she received two units of RBCs on the second postoperative day due to Hb of 6.1g/dL. Her urine was dark during surgery and postoperatively. Her posttransfusion plasma

An unusual case of an acute hemolytic transfusion reaction caused by an autoanti-I

In general, naturally occurring cold autoagglutinins react optimally at low temperatures. We describe a young child who experienced an acute hemolytic transfusion reaction by an unusual autoanti-I. The IgM autoanti-I was detected at 4°C (titer 256) and also reacted at 30°C. This case highlights the potential hazard of transfusing units of blood immediately upon removal from the blood refrigerator, especially into neonates and children of small stature.

Overt immediate hemolytic transfusion reaction attributable to anti-Wra

Wra is a low-prevalence antigen.  Anti-Wra is a relatively common antibody present in approximately 1 in 100 healthy blood donors.  Anti-Wra is reported to cause different degrees of hemolysis in transfusion and in HDN, ranging from benign to severe.  This report describes an acute overt hemolytic transfusion reaction in a patient whose serum contained anti-Wra and who received a Wr(a+) RBC component.

Fatal hemolytic transfusion reaction due to anti-Ku in a Knull patient

A fatal transfusion reaction due to anti-Ku in a Knull (Ko) patient is reported. The patient was transfused with 34 units of incompatible RBCs during 44 days of hospitalization. Apart from the first transfusion, all subsequent transfusions failed to raise the patient’s Hb. No serum antibody was identified until he was transferred to another hospital for dialysis. A compatibility test demonstrated a weak antibody and autocontrol reacting at room temperature by a manual polybrene method

The most common scenario involves a group A recipient receiving a platelet unit obtained via apheresis from a group O donor who has a high anti-A titer.2 As seen in the

These findings are consistent with a delayed hemolytic transfusion reaction (DHTR), mediated by anti-Joa, occurring 2 weeks after the first RBC transfusion.

Further testing confirmed that the patient's febrile response to transfusion was consistent with a nonhemolytic transfusion reaction and was unrelated to the drug-induced, pseudo ABO problem.

Severe intravascular hemolysis due to autoantibodies stimulated by blood transfusion

Autoantibodies may cause severe hemolytic anemia, but only rarely are they the cause of a hemolytic transfusion reaction due to the destruction of transfused allogeneic blood. In two patients, autoantibody was detected shortly after blood transfusion. The first case was a D-negative patient who produced an autoanti-Ce and subsequently developed hemoglobinuria and hyperbilirubinemia. The second case was a patient who developed an autoanti-Wrb that caused severe hemolysis that resulted in death.

–). For E+ patients with anti-e-like, R2R2 RBCs can be used; the alleles that result in e+var phenotypes are often associated with a D variant, however; therefore, stimulation of anti-D is a risk if a D variant has not been excluded (especially important in women of childbearing potential). Anti-CW is a relatively common antibody but has not been reported to cause a transfusion reaction, and IAT-compatible blood may be selected (approximately 97% of donors are CW–). Anti-CW has been implicated in HDFN

A method for obtaining autologous reticulocytes in ethylenediaminetetraacetic acid (EDTA) whole blood samples containing both autologous and transfused cells uses a microhematocrit centrifuge. The less dense reticulocytes harvested from the top 5 mm of microhematocrit tubes can be used to determine the patient’s phenotype or assess whether a transfusion reaction is taking place.
