Abstract

Neonatal Alloimmune Thrombocytopenia (NAIT), a complication of maternal alloimmunization against fetal platelets, is the result of immune destruction of platelets due to maternal antibodies in the early period. The cause of thrombocytopenia here is by antibodies developed against human platelet antigens frequently inherited from the mother. The clinical manifestations of NAIT extend from asymptomatic to severe bleeding. Platelet suspension can be used in the setting of severe thrombocytopenia or life-threatening bleeding. High-dose intravenous immunoglobulin (IVIG) therapy is another treatment option.

A case who had no clinical finding except diffuse ecchymoses after traumatic delivery, but was considered to have NAIT due to severe thrombocytopenia and was successfully treated with platelet suspension and IVIG is presented.
