Neonatal alloimmune thrombocytopenia (NAITP, NAIT, NATP or NAT) is a disease that affects babies in which the platelet count is decreased because the mother's immune system attacks her fetus' or newborn's platelets. A low platelet count increases the risk of bleeding in the fetus and newborn.
These antibodies cause neonatal alloimmune thrombocytopenia, post-transfusion purpura, and some cases of platelet transfusion refractoriness to infusion of donor platelets. [ 1 ] Overview
Therefore, ITP is a significant cause of fetal and neonatal immune thrombocytopenia. Approximately 10% of newborns affected by ITP will have platelet counts <50,000/uL and 1% to 2% will have a risk of intracerebral hemorrhage, comparable to that of infants with neonatal alloimmune thrombocytopenia (NAIT). [64] [65]
Thrombocytopenia affects a few newborns, and its prevalence in neonatal intensive care units is high. Normally, it is mild and resolves without consequences. Most cases affect preterm birth infants and result from placental insufficiency and/or fetal hypoxia.
CAMT is diagnosed by a bone marrow biopsy and is often initially suspected to be fetal and neonatal alloimmune thrombocytopenia. [3] Two types of Congenital amegakaryocytic thrombocytopenia have been identified with type I being more severe. [1] Treatment is mostly supportive, consisting of multiple platelet transfusions.

Hemolytic disease of the newborn, also known as hemolytic disease of the fetus and newborn, HDN, HDFN, or erythroblastosis fetalis, [1] [2] is an alloimmune condition that develops in a fetus at or around birth, when the IgG molecules (one of the five main types of antibodies) produced by the mother pass through the placenta.
