Although many cases are mild, NAIT is a significant cause of morbidity and mortality in newborns and is the most common cause of intracranial haemorrhage in full-term infants. Neonatal alloimmune thrombocytopenia (NAIT) In NAIT, the platelet equivalent of haemolytic dis-ease of the newborn, thrombocytopenia results from transplacental passage of maternal antibodies to fetal platelets expressing paternal human plate-let antigens (HPA) that the mother lacks.
