We report the case of a full-term (gestational age: 39 weeks) female newborn of a mother affected by immunothrombocytopenic purpura, treated with a high total dose (2 g/kg) of intravenous IgG, administered over a 3-day period starting 3 days before delivery. Infant platelet count at birth was 20,000/mm3 and she showed a great number of petechiae on the first day of life. After a random donor platelet transfusion and treatment with intravenous high-dose IgG (400 mg/kg for 5 days), platelet count began to increase. We conclude that exogenous IgG, even at high concentrations, apparently does not significantly cross the placenta, despite adequate maternal blood levels.

Abstract
We report the case of a full-term (gestational age: 39 weeks) female newborn of a mother affected by immunothrombocytopenic purpura, treated with a high total dose (2 g/kg) of intravenous IgG, administered over a 3-day period starting 3 days before delivery. Infant platelet count at birth was 20,000/mm3 and she showed a great number of petechiae on the first day of life. After a random donor platelet transfusion and treatment with intravenous high-dose IgG (400 mg/kg for 5 days), platelet count began to increase. We conclude that exogenous IgG, even at high concentrations, apparently does not significantly cross the placenta, despite adequate maternal blood levels.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
