[Neonatal hyperthyroidism caused by TSH receptor antibodies in maternal autoimmune hyperthyroidism].
Between July 1993 and December 1994 five term infants of mothers with Graves' disease were hospitalised at the Frühgeburtenstation of the Univ.-Frauenklinik Graz. Four Mothers had elevated TSH-receptor-antibody (TRAb)--levels during pregnancy, one had normalised TRAb-titers. In one case hyperthyroidism was first diagnosed during pregnancy. Three newborns had elevated TRAb-titers; in one of them thyrotoxicosis was diagnosed clinically and biochemically at the second day of life, one newborn had mild hyperthyroidism with tachycardia at the end of the first week of life and one newborn was asymptomatic by immediately initiated therapy. The two other newborns had normal thyroid hormone and antibody levels and no symptoms or signs of hyperthyroidism. The cases are reported and discussed in detail and our overall approach to diagnosis and treatment of neonatal hyperthyroidism in case of maternal Graves' disease will be given.
