Neonatal thrombocytopenia related to maternal idiopathic thrombocytopenic purpura (ITP) is reportedly uncommon but may have severe complications. The present report reviews records of 15 infants born to mothers with ITP during a 10‐year period, and the incidence of neonatal thrombocytopenia and the risk of hematological complications is examined. Severe thrombocytopenia (platelets < 50 000/μL) was seen in three infants despite successful therapy with high‐dose gamma globulin prior to delivery, which elevated maternal platelet counts. Although the platelet counts of these three infants fell to < 10 000/μL, none had severe complications. Moreover, no infants required treatment such as adrenocorticosteroids, platelets transfusion, or high doses of gamma globulin. No maternal markers predicted the degree of neonatal thrombocytopenia. The risk of complications arising from neonatal thrombocytopenia is low, but careful observation is required for the thrombocytopenic newborn of ITP mothers even when the infant has no bleeding complications at delivery.
