OBJECTIVE: Physiological gestational changes are associated with alterations in thyroid function which require different biochemical interpretation from that of non-pregnant women and necessitate established pregnancy-specific reference ranges. We aimed to identify the trimester-specific ranges of thyroid markers in a healthy population of pregnant Iranian women. METHODS: In this self-sequential study, data were extracted from The Tehran Thyroid Study; a total of 314 women were tested during the 1st, 2nd and 3rd trimesters for serum levels of thyrotropin (TSH), thyroxine (T4), free thyroxine index (FT4I) and thyroid peroxidase antibody (TPOAb)...

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...

BACKGROUND: Subclinical hypothyroidism is defined as an elevated thyroid-stimulating hormone level with a normal thyroxin level without signs or symptoms of hypothyroidism. Although it is well accepted that overt hypothyroidism has a deleterious impact on pregnancy, recent studies indicate that subclinical hypothyroidism may affect maternal and fetal health. Studies suggest an association between miscarriage and preterm delivery in euthyroid women positive for anti-peroxidase antibodies and/or anti-thyroglobulin antibodies...

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...

Recent studies have demonstrated that some hormones are present in baleen powder from bowhead (Balaena mysticetus) and North Atlantic right (Eubalaena glacialis) whales. To test the potential generalizability of this technique for studies of stress and reproduction in large whales, we sought to determine whether all major classes of steroid and thyroid hormones are detectable in baleen, and whether these hormones are detectable in other mysticetes. Powdered baleen samples were recovered from single specimens of North Atlantic right, bowhead, blue (Balaenoptera [B...

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...

Congenital goitre is a known cause of hypothyroidism in newborn. Congenital goitre can be due to defective synthesis of thyroxine or administration of antithyroid drugs to the mother during pregnancy. In this case report, we report an instance of a preterm male infant with antenatally detected goitre presenting as a neck mass with congenital hypothyroidism. Hormonal replacement therapy was started immediately after birth which lead to resolution of the mass and normalisation of thyroid function.
