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.

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.

FAQ

  • Q: What is the risk of acquiring certain viral infections?
  • A: Hepatitis B: 1:300,000 transfused units; hepatitis C: 1:1,800,000 transfused units; HIV: 1:2,300,000 transfused units
  • Q: What is the risk of developing bacterial sepsis?
  • A: 1:1,000,000 red cell units; 1:13,000 to 100,000 platelet units
  • 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.
