TSH, TRAb positivity associated with rebound Graves’ hyperth
For pregnant women with well-controlled Graves’ hyperthyroidism, subnormal thyroid-stimulating hormone levels and thyrotropin-receptor antibody positivity at drug withdrawal were linked to a rebound of Graves’ hyperthyroidism. A prospective study involved 63 pregnant women with well-controlled Graves’ hyperthyroidism who had stopped antithyroid drugs during early pregnancy. Researchers followed patients until the end of pregnancy and culled data on pregnancy outcomes. Data indicated that 31.7% of patients experienced a hyperthyroidism rebound.
