title: TSH-receptor antibodies in mothers with Graves' disease and outcome in their offspring.
abstract: Blood was taken from 56 selected newborn babies whose mothers had Graves' disease, to assess the relation between their thyroid function and the presence of thyrotropin (TSH) binding inhibitor immunoglobulins (TBII) and thyroid stimulating antibodies (TSAb) in maternal serum. All the mothers of the thyrotoxic babies had both these TSH receptor antibodies in their serum. However, most of the mothers whose thyroid function had been well controlled in pregnancy gave birth to normal babies. 15 babies had a transient syndrome of low serum thyroxine (T4) and free T4 with normal TSH and this tended to be associated with TSH receptor antibodies in maternal serum (TBII 9/15, TSAb 4/15). 2 infants had transient hyperthyroxinaemia without hyperthyroidism and both their mothers showed strong TSAb activity without TBII activity.
