ABSTRACT
Fetal and neonatal alloimmune thrombocytopenia (FNAIT) is a rare, life-threatening condition causing significant thrombocytopenia and bleeding with the risk of developing intracerebral hemorrhage (ICH). It results from maternal immunizations against fetal platelet antigens. Here, we report a case of a pregnant patient at 30 weeks gestation who presented to the hospital with a low platelet count of 90 th/mm3 and was found to have anti-human platelet antigen (HPA) 1a, 2b antibodies. She was treated with a weekly infusion of IV immunoglobulins. However, her condition was complicated by the development of hemolysis, elevated liver enzymes, and low platelets (HELLP) syndrome, which was treated promptly with a platelet transfusion and intravenous magnesium. Even though the child had severe thrombocytopenia and its associated complications, there were no signs of post-delivery thrombocytopenia or any other adverse effects. This case report highlights the importance of the antenatal management of the FNAIT to prevent severe fetal complications, such as ICH.
