Introduction
Newborns with type O blood have a certain chance of developing jaundice, but they are not particularly prone to it. ABO hemolytic disease commonly occurs when the mother is blood type O and the newborn is type A or B. Therefore, newborns with type O blood generally do not easily develop jaundice. However, they may still develop jaundice due to infections such as cytomegalovirus or Epstein-Barr virus, or due to congenital biliary atresia.
Newborns with blood type O may have a certain probability of developing jaundice, but they are not particularly prone to it.
Clinically, in cases of ABO hemolytic disease, during pregnancy or delivery, varying amounts of fetal red blood cells may enter the maternal circulation. If the mother's blood type is incompatible with that of the fetus and the mother lacks the antigens present on the fetal red blood cells, she may produce corresponding antibodies. These antibodies can cross the placenta and cause hemolysis in the fetus. This condition is most commonly seen when the mother is blood type O and the newborn is blood type A or B, potentially leading to hemolytic jaundice. Therefore, newborns with blood type O are generally less likely to develop jaundice. However, type O newborns may still develop infectious jaundice due to liver damage caused by infections such as cytomegalovirus (CMV) or Epstein-Barr virus (EBV). Additionally, conditions like congenital biliary atresia, which prevent timely excretion of bilirubin, can also lead to jaundice.
If a newborn develops jaundice with high bilirubin levels, prompt phototherapy with blue light is necessary to reduce bilirubin and prevent kernicterus.
