Abstract:

Fetal or neonatal alloimmune thrombocytopenia (NAIT) is the most common cause of severe thrombocytopenia in an otherwise healthy newborn. It occurs in approximately 1 in 1000 live births. NAIT is analogous to Rhesus (Rh) alloimmunization in pathophysiology. It is caused by the placental transfer of maternal alloantibodies against fetal platelet antigens inherited from the father. The transplacental transfer of maternal alloantibodies against fetal platelet antigens leads to the destruction of fetal antigen-positive platelets. Presentation of NAIT varies from an incidentally detected mild thrombocytopenia in a well newborn to life threatening in-utero or postnatal intracranial hemorrhage (ICH). Unlike Rh alloimmunization, it may present unexpectedly in a first pregnancy in 40-60% of cases. It has often been observed to be more severe in subsequent pregnancies. As such it is important that the diagnosis of NAIT be considered in the work up of all cases of neonatal thrombocytopenia in order to determine the risk to future pregnancies and corresponding management plans. In this talk the pathogenesis, and incidence of NAIT as well as the current antenatal and postnatal management of this condition will be discussed.
