Hydrops foetalis in 3 infants of a mother with acquired chronic pure red cell aplasia: transitory red cell aplasia in 1 of the infants.
A young woman with acquired chronic pure red cell aplasia (PRCA) gave birth to 3 infants with foetal hydrops. The 1st infant died shortly after birth, while the 2nd was stillborn with severe anaemia. Both had signs of increased erythropoiesis at autopsy. The 3rd infant was saved by foetal intrauterine red cell transfusions into the hepatic part of the umbilical vein. This infant had red cell aplasia lasting for about 3 months after birth, but then recovered. We believe that antibodies to red cell progenitors in the bone marrow were transferred transplacentally from mother to foetus, giving rise to severe affection of these infants. To the best of our knowledge this has not been reported previously in PRCA.
