[Hashimoto's disease with pregnancy].

That normal pregnancy, PIH and Hashimoto's were all closely related with human immunology has been reported by many authors. Six pregnant women with Hasimoto's were studied. Among them four were complicated with PIH, and one with postpartum transient hypothyroidism. MCHA and TGHA were slightly decreased in 2 cases during pregnancy and one congenital hypothyroidism happened among 6 neonates. Our data indicates that pregnancy and Hashimoto's can affect each other.
