    Abstract:
    Anti-D prophylaxis should be proposed to all RhD negative non-sensitized pregnant women, after delivering an information concerning both Rhesus disease and anti-D immunoglobulins. This information must be delivered as a written document and the patient's oral consent is required before administration of the anti-D immunoglobulins. Anti-D immunoglobulins currently used in France for prophylaxis are extracted from plasma of hyperimmunized paid donors. Even if all the conditions of viral safety are fulfilled in the preparation of anti-D immunoglobulins, they remain blood derived products. As such, prescription of anti-D immunoglobulins should follow legal rules concerning tracability and information. Refusal of rhesus prophylaxis can occur but should be transcribed and motivated in the patient's chart. Administration of anti-D immunoglobulins is usually well tolerated. Reactions to hemolysis of fetal Rhesus positive red cells can occur but remain rare and linked to important foeto-maternal hemorrhage. They can be easily prevented or treated by anti-inflammatory drugs. Patients can be vaccinated against rubella in the post-partum period even though they will receive a concomitant prophylaxis with Rh immunoglobulin. Persistence of passive anti-D in maternal circulation after injection lasts several weeks or months and could have various consequences. In the mother: it can interfere with diagnosis of active anti-D immunization. In most cases, it may be possible to differentiate passive and immune anti-D. When reliable information concerning date and dosage of antenatal anti-D prophylaxis are available. In the newborn: anti-D immunoglobulins can pass through the placenta and enter the fetal circulation, coat the D positive fetal red cells and give positive DAT. Positive DAT is reported in 5 to 15% of the newborns following rhesus prophylaxis in the third trimester but with no report of anemia or jaundice. In absence of ABO incompatibility, no additional investigation is needed in these newborns.
