Rh disease is a cause of hemolytic disease of the newborn.

• During birth, the mother may be exposed to the infant's blood, causing the development of antibodies, which may affect the health of subsequent Rh+ pregnancies
• It typically only occurs in a 2nd (or subsequent) pregnancy of Rh negative women, where the fetus' father is Rh positive, leading to a Rh+ pregnancy

• Ranges from mild to severe

• In mild cases, the fetus may have mild anemia with reticulocytosis
• In moderate/severe cases, the fetus may have more marked anemia, and erythroblastosis fetalis (hemolytic disease of the newborn)
• When very severe, it may cause hydrops fetalis, or stillbirth

• Generally preventable by Tx the mother during pregnancy, or soon after delivery, with an IM injection of anti-RhD immunoglobulin (aka anti-D)
