Transfusion Reaction
Basics
Description
- Any acute or subacute adverse reaction that develops as a consequence of the administration of blood components
- Types include the following:
- Acute reactions: hemolytic, febrile, allergic, anaphylactic, septic, transfusion-related acute lung injury (TRALI), transfusion-associated circulatory overload (TACO)
- Delayed reactions: delayed hemolytic, transfusion-associated graft-versus-host disease (TA-GVHD)
- Late complications of transfusion: infection, alloimmunization, iron overload
Epidemiology
- 1% of pediatric blood product recipients develop some type of transfusion reaction.
- Transfusion associated with death in 1 in 200,000 to 420,000 transfused units
Pathophysiology
- Acute hemolytic transfusion reaction
- Antigen–antibody interaction leads to complement activation on the surface of the transfused RBCs, resulting in acute intravascular hemolysis and vasomotor instability.
- Usually ABO blood group incompatibility
- Most commonly due to medical error
- Febrile nonhemolytic transfusion reaction (FNHTR)
- Cytokines released by leukocytes in the product
- 40% of patients with one febrile reaction will have a subsequent one.
- Urticarial (allergic)
- IgE-mediated
- Recipient allergic response to donor plasma proteins or other constituents of plasma
- Sporadic and donor dependent
- Anaphylactic
- Overwhelming acute allergic reaction; can be mediated by anti-IgA formed by a recipient who is IgA deficient and receives blood products containing IgA
- Bacterial sepsis
- Intravascular infusion of viable bacteria and endotoxins leads to fever, chills, and/or acute septic shock.
- Contaminated blood product; most commonly a platelet product near the end of shelf life
- Delayed hemolytic transfusion reaction (DHTR)
- Previously transfused patients who are sensitized to a minor blood group antigen, especially Jka or Jkb (Kidd antigen), develop an anamnestic response on reexposure.
- Antibody is below detectable levels in antibody screen and crossmatch; after transfusion, titers rise (usually within 2 to 10 days) and extravascular hemolysis occurs.
- TRALI
- Antileukocyte antibodies or neutrophil-activating factors in transfused product interact with recipient neutrophils, causing leukocyte aggregates that deposit in the lung.
- Multiparous female donors with HLA sensitization often are implicated.
- TACO
- Circulatory overload leading to heart failure
- Administration of an excessive volume of a blood product or infusion at an excessive rate
- TA-GVHD
- Patients with inherited or acquired T-cell immunodeficiency can develop TA-GVHD from transfused immunocompetent T cells.
- Can also occur if the donor and recipient are related and share HLA types

Diagnostic Tests and Interpretation
Initial Tests
- Acute hemolytic
- Direct Coombs test: positive
- CBC: anemia
- Urinalysis: hemoglobinuria
- Prothrombin time (PT), partial thromboplastin time (PTT), fibrinogen, fibrin split products: disseminated intravascular coagulation (DIC)
- FNHTR
- Direct Coombs test: negative or no change from pretransfusion
- Immediate Gram stain of the product
- Blood culture of the patient and product
- All results should be negative; a diagnosis of exclusion
- Urticarial
- No specific testing
- Anaphylactic
- IgA level in recipient. If undetectable, test for anti-IgA antibody (of the IgE class).
- Bacterial sepsis
- Immediate Gram stain and blood culture of the transfused product: result positive for bacteria
- DHTR
- CBC: anemia
- Bilirubin: elevated
- Indirect Coombs test (antibody screen): positive
- Direct Coombs test: positive (mixed field) if done early
- TRALI
- Leukocyte antibody testing in the implicated donor(s)
- Chest radiograph: increased pulmonary vascular markings or infiltrates for hypervolemia (TACO) and TRALI
Treatment
General Measures
- Acute hemolytic
- Stop transfusion immediately.
- Supportive care with hydration, pressors, and diuretics to maintain circulation and urine output
- FNHTR
- Stop transfusion.
- Antipyretics (acetaminophen)
- Demerol for severe chills and rigors
- May resume transfusion if patient is stable and acute hemolytic transfusion reaction and bacterial sepsis are ruled out
- Urticarial
- Stop transfusion.
- Antihistamine (diphenhydramine)
- Steroids or epinephrine in severe reactions
- Transfusion may be resumed if mild reaction.
- Anaphylactic
- Epinephrine
- IV fluids, pressors
- Respiratory support
- Bacterial sepsis
- Stop transfusion.
- Fluids if hypotensive
- Antibiotics to eradicate Staphylococcus and Gram negatives including Yersinia species
- DHTR
- Depends on degree of hemolysis; if profound, management as acute hemolytic reaction. If mild, no therapy may be needed.
- TRALI
- Supportive care; usually resolves in 12 to 24 hours
- TACO: diuretics (furosemide)
- TA-GVHD: no treatment; almost always fatal
- General prevention
- Acute hemolytic
- Proper labeling of blood specimens and products and adherence to procedures for correct identification of product and recipient will eliminate most acute hemolytic transfusion reactions.
- FNHTR
- Administration of leukodepleted blood products, especially for long-term transfused patients who have a high incidence of febrile transfusion reactions
- No evidence to support premedication with acetaminophen or diphenhydramine to prevent FNHTR
- Urticarial
- Administration of washed erythrocyte products (in patients with repeated or severe allergic reactions)
- No conclusive evidence to support premedication with antihistamines
- Anaphylactic
- If due to anti-IgA in an IgA-deficient recipient, provision of IgA-deficient products may be possible.
- Bacterial sepsis
- Sterile technique in blood collection, storage, and administration; inspection of product before transfusion
- Bacterial screening of platelet products before they are transfused
- DHTR
- Appropriately performed antibody screen and crossmatch as pretransfusion testing
- Check blood bank records for previous antibodies.
- TRALI
- Deferral of donors is implicated in proven TRALI cases.
- TACO
- Administer appropriate volumes (typically 10 to 15 mL/kg) at appropriate rate, usually over 3 to 4 hours unless hypovolemic or actively bleeding.
- Patients with chronic anemia are euvolemic and should be transfused with smaller volumes over longer time periods.
- TA-GVHD
- Patients at risk (immunocompromised, neonates) must receive irradiated blood products.
- Acute hemolytic
Ongoing Care
Complications
- Posttransfusion hepatitis: caused by hepatitis B or C viruses, others
- AIDS: caused by HIV
- Cytomegalovirus (CMV)
- Symptomatic infection in patients with inherited or acquired immunodeficiency states, premature neonates
- These individuals should receive CMV-safe products.
- Other transfusion-transmissible infections
- Epstein-Barr virus, syphilis, malaria, toxoplasmosis, human T-cell lymphotropic virus I (HTLV-I), Chagas disease, babesiosis, filariasis, West Nile virus, parvovirus B19
- Alloimmunization
- Formation of antibodies to erythrocyte, platelet, and HLA antigens can develop in some multiply transfused patients; may cause delays in pretransfusion testing, febrile transfusion reactions, DHTR, and platelet transfusion refractoriness
- HLA alloimmunization may also affect eligibility and organ procurement for solid organ transplantation.
- Iron overload
- Long-term transfusion recipients will accumulate iron as a by-product of erythrocyte breakdown.
- An iron-chelating drug will enhance its excretion.

- Q: Is directed donor blood safer?
- A: No. There is no evidence that the infection risk is lower, and some studies suggest that the infection risk may be higher.
