Pregnant women with gestational trophoblastic disease have an increased likelihood to develop hyperthyroidism secondary to increased secretion of human chorionic gonadotropin. Most of these cases of hyperthyroidism remain undiagnosed and may present as a thyrotoxic crisis during the perioperative period. Pregnant patients with gestational trophoblastic disease should be always evaluated for hyperthyroidism, and in cases of severe hyperthyroidism, antithyroid treatment should be initiated before evacuation of the mole...

Iodine is an important micronutrient required for nutrition. Excess iodine has adverse effects on thyroid, but there is not enough information regarding its effect on salivary glands. In addition to food and iodized salt, skin disinfectants and maternal nutritional supplements contain iodide, so its intake could be excessive during pregnancy, lactation, and infancy. The aim of this work was to evaluate the effect of excess iodide ingestion on salivary glands during mating, gestation, lactation, and postweaning period in mouse...

REVIEW
Simone De Leo, Elizabeth N Pearce
Understanding of changes in thyroid function and the consequences of thyroid disease during pregnancy has rapidly grown in the past two decades, and revised American Thyroid Association guidelines on this topic were published in 2017. This Review explores the association between thyroid autoimmunity and complications during and after pregnancy. Thyroid autoimmunity refers to the presence of antibodies to thyroperoxidase or thyroglobulin, or thyroid-stimulating hormone receptor antibodies (TRAbs), or a combination of these, and is present in up to 18% of pregnant women...

INTRODUCTION: Thyroid hormone is known to play important role during embryo implantation, however mechanisms underlying its actions in uterus during peri-implantation period has not been fully identified. In this study, we hypothesized that thyroid hormone could affect expression of proteins related to its function, where these could explain mechanisms for its action in uterus during this period. METHODS: Female rats, once rendered hypothyroid via oral administration of methimazole (0...

OBJECTIVE: In the recently revised guidelines on the management of thyroid dysfunction during pregnancy, treatment with thyroid hormone (LT4) is not recommended in women without thyroid autoimmunity (TAI) and TSH levels in the range 2.5-4.0 mIU/L, and in a recent study in that particular group of pregnant women, more complications were observed when a treatment with LT4 was given. The objective of the study was therefore to investigate whether variation in thyroid function within the normal (non-pregnant) range in women free of thyroid disease was associated with altered pregnancy outcomes? DESIGN: Cross-sectional data analysis of 1321 pregnant women nested within an ongoing prospective collection of pregnant women's data in a single centre in Brussels, Belgium...

R G Ahmed
Exposure to polychlorinated biphenyls (PCBs) is related to several endocrine disorders. This study examined the effect of maternal exposure of 3,3',4,4',5-pentachlorobiphenyl (PCB 126) on the fetoplacental unit and fetal thyroid-cytokine axis during the pregnancy. Pregnant albino rats received PCB 126 (20 or 40μg/kgb.wt.) by oral gavage from gestation day (GD) 1 to 20. Potential effects of PCB 126 were evaluated by following the histopathological changes in the placenta by Haematoxylin and Eosin (H&E) stain and measuring the maternofetal thyroid axis (ELIZA), maternofetal body weight, and fetal growth markers (ELIZA), and cytokines (ELIZA) at embryonic day (ED) 20...

PURPOSE: The purpose of this study is to examine the association between maternal asthma and pregnancy, delivery and neonatal outcomes. MATERIALS AND METHODS: We carried out a retrospective cohort study using the Health Care Cost and Utilization Project-Nationwide Inpatient Sample (HCUP-NIS) database from 2003 to 2011. Among women who delivered during this time period, we compared pregnancy, delivery, and neonatal outcomes in asthmatics versus non-asthmatics. Multivariate logistic regression was used to estimate adjusted odds ratios and 95% confidence intervals...

OBJECTIVE: The correct diagnosis of hypothyroidism during pregnancy requires knowledge of the local trimester-specific thyrotropin (TSH) reference ranges. When these are not available, the guidelines recommend upper limits of 2.5, 3.0, and 3.0μU/ml for the 1(st), 2(nd), and 3(rd) trimesters, respectively. The aim is to establish the reference range for our local population. MATERIAL AND METHODS: A population-based observational study was performed on healthy pregnant women from 11 healthcare centres in the province of Huelva...

BACKGROUND: Triclosan, an antimicrobial agent used in some consumer products, reduces endogenous thyroid hormone concentrations in rodents. Despite ubiquitous triclosan exposure and the importance of thyroid hormones for normal fetal development, few human studies have examined the impact of triclosan exposure on maternal, neonatal, or child thyroid hormones. METHODS: In the HOME Study, a prospective cohort from Cincinnati, OH, we measured urinary triclosan concentrations up to three times in pregnant women between 16weeks and delivery, and up to three times in children between age 1-3years...

Context: Neonatal hyperthyroidism was first described in 1912 and in 1964 was shown to be linked to transplacental passage of maternal antibodies. Few multicenter studies have described the perinatal factors leading to fetal and neonatal dysthyroidism. Objective: To show how fetal dysthyroidism (FD) and neonatal dysthyroidism (ND) can be predicted from perinatal variables, in particular, the levels of anti-thyrotropin receptor antibodies (TRAbs) circulating in the mother and child...
