Idiopathic thrombocytopenic purpura (ITP) during pregnancy may cause serious bleeding in the mother and fetus. Therapy with high-dose intravenous immunoglobulins has caused an immediate and predictable rise in platelet count in both adults and children with chronic or acute ITP. We report our experience in managing a woman near term in pregnancy. The patient demonstrated a rapid increase in platelet count, delivered without excessive bleeding and had a normal child with normal platelet count. Intravenous immunoglobulins may offer a new and safe way to control maternal and fetal platelet counts during pregnancy, delivery and neonatal period.
