High-dose IgG treatment for neonatal alloimmune thrombocytopenia

Abstract
Twelve children with neonatal alloimmune thrombocytopenia (NAT) due to Zwa incompatibility were treated with intravenous IgG (IVIG). Total doses ranged between 1 and 9 g. Ten out of 12 infants had a favorable response. It is concluded that IVIG can serve as an emergency treatment in NAT if material (or compatible) platelets are not available.
