[Clinical and immune hematologic problems in prenatal prevention of Rhesus sensitization].
Various studies have provided impressive evidence of the efficacy of antenatally administered anti-D in the prevention of rhesus (D) alloimmunisation in rhesus-negative women. However, possible clinical and immunohaematological problems associated with this prophylactic therapy have received little attention. We describe perinatal and immunohaematological problems, which occurred in four cases after antenatal rhesus prophylaxis. Classical immunohaematological techniques were employed, to detect and specify irregular red cell antibodies. It was found, that the antenatal administration of anti-D could mask sensitization to other red cell antigens or the production of maternal immune anti-D antibodies later in pregnancy. A further problem encountered was that of neonates with a positive direct Coombs' test (the uncertainty in the individual case being, whether this is a result of the antenatal administration of anti-D) and marked hyperbilirubinaemia. Antenatal immunoprophylaxis for rhesus disease can give rise to immunohaematological and clinical findings, of which the interpretation is extremely difficult and requires intensive cooperation between the obstetrician, neonatologist, and haematologist/clinical biochemist.
