Study Notes

Overview of Hemolytic Disease of the Fetus and Newborn (HDFN)

  • Also known as erythroblastosis fetalis, HDFN involves maternal antibodies attacking fetal or newborn red blood cells (RBCs).
  • Main classifications: Rh hemolytic disease and ABO hemolytic disease, each requiring different management strategies.

Rh Hemolytic Disease

  • Interaction: Occurs when an Rh-negative mother is pregnant with an Rh-positive fetus.
  • Mechanism:
    • First Pregnancy: Maternal exposure to Rh-positive fetal blood during delivery leads to the formation of anti-D IgG antibodies.
    • Subsequent Pregnancies: Anti-D IgG crosses the placenta, attacking Rh-positive fetal RBCs, resulting in hemolysis.
  • Presentation:
    • Hydrops Fetalis: Severe condition with fluid buildup in the fetus; potentially life-threatening.
    • Jaundice: Appears shortly after birth due to high bilirubin levels.
    • Kernicterus: Brain damage resulting from high bilirubin concentrations.
  • Treatment/Prevention:
    • Prevention: Administer anti-D IgG (Rho(D) immune globulin) to Rh-negative mothers during the third trimester and within 72 hours postpartum for Rh-positive fetuses.
    • Treatment: Phototherapy for jaundice management; severe cases may require intrauterine transfusions or exchange transfusions.

ABO Hemolytic Disease

  • Interaction: Primarily occurs when a type O mother has a fetus with type A or B blood.
  • Mechanism: Mothers may have pre-existing anti-A and/or anti-B IgG antibodies that can cross the placenta, attacking fetal RBCs.
  • Presentation:
    • Mild Jaundice: Typically appears within the first 24 hours post-birth; less severe than Rh hemolytic disease.
    • Can occur in firstborn babies, differentiating it from Rh hemolytic disease.
  • Treatment/Prevention:
    • Prevention: No specific preventive measures exist; management focuses on treating affected newborns.
    • Treatment: Phototherapy for bilirubin level management; exchange transfusions may be necessary in severe cases.

Key Differences

  • Rh hemolytic disease is more manageable and preventable with appropriate care, while ABO hemolytic disease is often less predictable and typically less severe.
