Thyroid function among women with gestational trophoblastic diseases. A cross-sectional study

Abstract: BACKGROUND: Gestational trophoblastic diseases (GTDs) are treatable rare tumors with wide distribution. The estimated incidence of GTDs varies dramatically between different regions globally. In early pregnancy, there may be high human chorionic gonadotropin (HCG) concentrations, normal or slightly increased free T4 (fT4) and subnormal thyroid-stimulating hormone (TSH), causing hyperthyroidism ranging from subclinical to severe. Beta-HCG causes thyrotoxicosis through thyroid stimulation in patients with tropho… Show more

“…The women's clinical state was not assessed in this study, which solely looked at biochemical hyperthyroidism. 12 The discovery of greater incidence of biochemical hyperthyroidism in CM supports the findings of the previously mentioned 2015 US study. 20 Several research have investigated GTD hyperthyroidism's pathophysiology.…”

“…According to previous several studies, hyperthyroidism is one of complications of GTN. In this study, 8 (5%) GTN patients had hyperthyroidism and this was attributed to the molecular similarity of hCG with Thyroid-Stimulating Hormone (TSH), causing crossreactivity with the TSH receptor and leading to the stimulation of the thyroid gland [12,13].…”

“…The difference between hyperthyroidism in whole moles and partial moles illustrates how hyperthyroidism in GTD can be missed in the absence of routine biochemical screening. In a Turkish cross-sectional study [17], thyroid function was evaluated in women with GTD, and outcomes in PM and CM were compared. When compared to women with a pathologically confirmed diagnosis of PM, women with CM had greater total T4 (mean 17.04 vs 2.04), higher free T4 (mean 2.15 vs 1.64), and lower TSH (mean 0.28 vs 0.91).…”
