Prenatal high-dose immunoglobulin treatment for neonatal hemochromatosis: a case report and review of the literature.

Neonatal hemochromatosis is a difficult disorder to cure, and it has a high rate of recurrence. High-dose immunoglobulin treatment is very effective as prenatal treatment for recurrent neonatal hemochromatosis. A 34-year-old pregnant Japanese woman underwent high-dose immunoglobulin treatment for recurrent neonatal hemochromatosis. High-dose non-specific intravenous immunoglobulin (1 g/kg bodyweight) was administered to the mother intravenously every week from 18 until 36 gestational weeks. A male infant was delivered at 37 weeks of gestation, and his condition was favorable, including hepatic function. The use of γ-globulin for neonatal hemochromatosis appears adequately validated by experience.
