The outcome analysis of 10 pregnancies at risk for neonatal alloimmune thrombocytopenia (NAIT) is presented. An experimental protocol of cordocentesis and maternal administration of intravenous immunoglobulin (IVIG) is compared to a control group of older untreated affected siblings. The outcome in pregnancies treated with IVIG shows improved fetal platelet count in 70% and no intraventricular hemorrhage. We conclude that maternal administration of IVIG appears to improve clinical outcome in fetuses at risk for NAIT.
