Full Form of HDN
What is HDN?
Hemolytic Disease of the Newborn (HDN) is a blood disorder in newborns caused by maternal-fetal blood group incompatibility, most commonly Rh or ABO. When a mother lacks the Rh factor and carries an Rh-positive baby, her immune system may produce antibodies that cross the placenta and destroy fetal red blood cells. This leads to hemolysis, causing anemia, jaundice, and potentially kernicterus. In India, HDN remains a significant cause of neonatal morbidity, especially in areas with limited access to prenatal Rh screening. Diagnosis is confirmed by a positive direct Coombs test and elevated bilirubin levels. Management includes phototherapy for mild cases, intravenous immunoglobulin to reduce hemolysis, and exchange transfusion in severe cases. Prevention through Rh immunoglobulin administration to Rh-negative mothers after delivery has dramatically reduced incidence. HDN is a key topic in MBBS, NEET PG, and AIIMS exams, often tested for its pathophysiology and management. Timely intervention in Indian hospitals has improved outcomes, but awareness among healthcare providers remains crucial. The condition is also known as erythroblastosis fetalis. With proper antenatal care, most cases are now preventable.
