[Antithyroid drug therapy in pregnancy. An indication for pregnancy interruption based on fetal indications?]. 1985

J Wisser, and R Knitza, and H Hepp

Antithyroid drugs can pass the placenta, in contrast to thyroid hormones. Therefore, their application in pregnancy carries the potential risks of teratogenic effects and foetal hypothyroidism. The actual danger to the foetus, however, is controversial. The history of a hyperthyroid patient treated with carbimazole and referred for termination of pregnancy in the 8th week of gestation gave rise to review the literature in order to elucidate the foetal risks. Data of 278 pregnant women treated with imidazole derivatives (group I) and 192 women, who received thiouracil derivatives (group II) during pregnancy, were found in the literature. The rates of foetal malformations and foetal goitre in group I were 3.6% and 3.2%, respectively. In group II the corresponding rates were 3.6% for foetal malformation and 7.8% for foetal goitre. From these figures we conclude that antithyroid therapy in pregnancy does not warrant termination of pregnancy for foetal reasons if there is meticulous control of maternal thyroid metabolism.

UI	MeSH Term	Description	Entries
D006980	Hyperthyroidism	Hypersecretion of THYROID HORMONES from the THYROID GLAND. Elevated levels of thyroid hormones increase BASAL METABOLIC RATE.	Hyperthyroid,Primary Hyperthyroidism,Hyperthyroidism, Primary,Hyperthyroids
D007037	Hypothyroidism	A syndrome that results from abnormally low secretion of THYROID HORMONES from the THYROID GLAND, leading to a decrease in BASAL METABOLIC RATE. In its most severe form, there is accumulation of MUCOPOLYSACCHARIDES in the SKIN and EDEMA, known as MYXEDEMA. It may be primary or secondary due to other pituitary disease, or hypothalamic dysfunction.
