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.
