Graves' disease is the most frequent cause of hyperthyroidism in iodine-sufficient geographical areas and is characterized by the presence in patients' serum of autoantibodies directed against the thyrotropin receptor (TRAb) that cause overproduction and release of thyroid hormones. Clinical presentation results from both hyperthyroidism and underlying autoimmunity. The diagnosis is based on characteristic clinical features and biochemical abnormalities. If serum thyrotropin (TSH) is low, serum free thyroxine (FT4) and free triiodothyronine (FT3) concentrations should be measured to distinguish between subclinical (with normal circulating thyroid hormones) and overt hyperthyroidism (with increased circulating thyroid hormones)...

This study aimed to investigate the consequences of maternal exposure to iodine excess (IE; 0.6 mg NaI/L) throughout pregnancy and lactation on the hypothalamus-pituitary-thyroid axis of the male offspring in adulthood. Maternal IE exposure increased hypothalamic Trh mRNA expression and pituitary Tsh expression and secretion in the adult male offspring. Moreover, the IE-exposed offspring rats presented reduced thyroid hormones levels, morphological alterations in the thyroid follicles, increased thyroid oxidative stress and decreased expression of thyroid differentiation markers (Tshr, Nis, Tg, Tpo, Mct8) and thyroid transcription factors (Nkx2...

Thyroid diseases may adversely affect the conception, maintain pregnancy. They increase the risk of complications in pregnancy and may have a negative effect on the fetus. Therefore it is necessary to capture thyroid diseases in the population of pregnant women, in the early stage of pregnancy. In Slovakia, since 2009, the Expert Guideline of the Ministry of Health of the Slovak Republic for the diagnosis and treatment of autoimmune thyroid diseases in women during pregnancy has been in force. In our patient cohort, we monitored 666 pregnant patients, the timeliness of screening, thyroid parameters, the number of pregnancies and their complications, the need for levothyroxine treatment...

Background: The hydatidiform mole (HM) is a precancerous placenta considered as a gestational trophoblastic disease (GTD). It may convert to more invasive forms of gestational trophoblastic neoplasia (GTN), endangering women’s health by more severe complications. Most GTN cases originate from HM, which is associated with uterine bleeding, preeclampsia and thyroid problems. Its etiology has not been adequately explored, but some risk factors have been reported. The aim of the present study was to assess any relationships between molar pregnancy and factors including mothers’ and husbands’ occupations...

Thyroid hormones are essential for an adequate growth and development of the foetus. In addition to the classical association between maternal hypothyroidism and neurological impairment in the progeny, other adverse reproductive events have been associated with maternal thyroid dysfunction including infertility, miscarriage and preterm delivery. Although all scientific societies endorse the treatment of overt hypothyroidism; the management and/or treatment of subclinical hypothyroidism, hypothyroxinemia or antithyroid antibody-positive women should be considered with caution...

Thyroid dysfunction is the commonest endocrine disorder in pregnancy apart from diabetes. Thyroid hormones are essential for fetal brain development in the embryonic phase. Maternal thyroid dysfunction during pregnancy may have significant adverse maternal and fetal outcomes such as preterm delivery, preeclampsia, miscarriage and low birth weight. In this review we discuss the effect of thyroid disease on pregnancy and the current evidence on the management of different thyroid conditions in pregnancy and postpartum to improve fetal and neonatal outcomes, with special reference to existing guidelines on the topic which we dissect, critique and compare with each other...

Thyroid autoimmunity (TAI) appears to play a crucial role in female infertility, recurrent pregnancy loss and IVF failure. Thyroid autoantibodies against thyroid peroxidase and thyroglobulin have been shown to represent an independent risk factor for infertility and miscarriage. Moreover, thyroxin hormone administration reduces the risk of obstetrical complications in TAI positive women. The aim of our present study was to investigate the immunological background of female infertility and recurrent pregnancy loss in euthyroid and subclinical hypothyroid women with TAI focusing on innate immunity...

Women submitted to ART treatments represent a select subgroup of individuals. Several studies have described the relationship between TAI and pregnancy outcomes as a result of ART, with contradictory results. The purpose of this systematic review was to determine the association between TAI and the risk of miscarriage in pregnancies resulting from ART. MEDLINE via PubMed, LILACS and Embase were searched for studies published in peer-reviewed journals from 1999 to 2017. The studies were summarized using the fixed effects model and the Peto's method to calculate RR in order to flesh out the association between TAI and spontaneous abortion...
