Mc. Dooren et Cp. Engelfriet, PROTECTION AGAINST RH D-HEMOLYTIC DISEASE OF THE NEWBORN BY A DIMINISHED TRANSPORT OF MATERNAL IGG TO THE FETUS, Vox sanguinis, 65(1), 1993, pp. 59-61
IgG present in the circulation of newborn infants is predominantly of
maternal origin. In cases of severe Rh D alloimmunization, the materna
l anti-D antibodies may lead to Rh D-haemolytic disease of the newborn
. However, an impaired placental transport of maternal IgG could be as
sociated with the protection of the fetus/newborn against haemolytic d
isease as shown in this case report.
