An editorial published in the journal Transfusion, discusses the potential for developing anti-human platelet antigen (HPA)-1a prophylactic methods to prevent fetal and neonatal alloimmune thrombocytopenia (FNAIT), which occurs in 86 out of every 100,000 live births. Recent work in mouse models suggests that it may be possible to develop a prophylactic antibody for use in susceptible patients to remove or destroy fetal platelets in the maternal circulation. This method would be similar to the current use of anti-D prophylaxis for preventing hemolytic disease of the fetus and newborn.
