Thyroid Hormone Treatment among Pregnant Women with Subclinical Hypothyroidism: U.S. National Assessment

Mayo Clinic researchers conducted a study to estimate the effectiveness and safety of thyroid hormone treatment among pregnant women with subclinical hypothyroidism. Among 5,405 pregnant women with subclinical hypothyroidism, 843 with a mean pre-treatment TSH concentration were treated with thyroid hormone and 4,562 with a mean baseline TSH concentration were not treated. Pregnancy loss was significantly less common among treated women than among untreated women. Compared with the untreated group, treated women had lower adjusted odds of pregnancy loss but higher odds of preterm delivery, gestational diabetes, and pre-eclampsia; other pregnancy related adverse outcomes were similar between the two groups. Based on the results, thyroid hormone treatment was associated with decreased risk of pregnancy loss among women with subclinical hypothyroidism, especially those with pre-treatment TSH concentrations. However, the increased risk of other pregnancy related adverse outcomes calls for additional studies evaluating the safety of thyroid hormone treatment in this patient population. The study was published in BMJ.
