title: High-dose intravenous gammaglobulin for neonatal alloimmune thrombocytopenia in twins.
abstract: We report the successful treatment of neonatal alloimmune thrombocytopenia with repeated infusions of high-dose immunoglobulin G (400 mg/kg/d for 5 days) in twins. Platelet counts increased within 3 days from less than 20 x 10(9)/l to more than 70 x 10(9)/l. The first twin survived without neurological or other sequelae. The second twin had probably developed intracranial hemorrhage (ICH) in utero. This infant developed long-term neurological sequelae with blindness, cerebral palsy and infantile spasms. Implications of the therapeutic approach and prevention of severe complications in pregnancies with known risk for neonatal alloimmune thrombocytopenia are discussed.
