We describe the case of an African woman who was diagnosed with ketosis-prone diabetes with diabetes-associated autoantibodies, after being admitted for diabetic ketoacidosis (DKA) precipitated by her first presentation of systemic lupus erythematosus (SLE). She had a seven-year history of recurrent gestational diabetes (GDM) not requiring insulin therapy, with return to normoglycaemia after each pregnancy. This might have suggested that she had now developed type 2 diabetes (T2D). However, the diagnosis of SLE prompted testing for an autoimmune aetiology for the diabetes, and she was found to have a very high titre of GAD antibodies...

Limited studies have consistently shown an association of phthalates exposure with thyroid hormones (THs) in pregnant women. However, it remains unknown on which specific phthalates can affect THs and whether any effects could differ by gestational age. In the present study, we investigated associations between serum concentrations of phthalate monoesters [monoethyl phthalate (MEP), mono-(n + iso)-butyl phthalate (MBP) and mono(2-ethylhexyl) phthalate (MEHP)] and THs [thyroid-stimulating hormone (TSH), total thyroxine (TT4) and free thyroxine (FT4)] in Chinese pregnant women...

Pregnancy and postpartum are periods of high susceptibility to major depression (MD) and other mood disorders. The peripartum period is also a time of considerable changes in the levels of hormones, including cortisol, thyroid-stimulating hormone (TSH), prolactin, gonadotropins, and gonadal steroids. To investigate the relationship between mood and hormonal changes during and after pregnancy, we reviewed published reports of hormonal measures during this time frame, searched via PubMed and Web of Science. Studies were included if women in the antepartum or postpartum periods were clinically diagnosed with MD, and if there were repeated measures of cortisol, TSH, or prolactin...

A clinical association between thyroid dysfunction and pregnancy complications has been extensively reported, however the molecular mechanisms through which TH might regulate key-events of pregnancy have not been elucidated yet. In this respect, we performed in vivo studies in MMI- induced hypothyroid pregnant mice, evaluating the effect of hypothyroidism on the number of implantation sites, developing embryos/resorptions and pups per litter, at 4.5, 10.5, 18.5 days post coitum (dpc) and at birth. We also studied the expression of major molecules involved in implantation and placentation, such as the proteases ISPs, MMPs, TIMPs and Notch pathway related genes...

BACKGROUND: Management guidelines about the thyroid disease in pregnancy are silent about the postpartum course of new onset subclinical hypothyroidism (SCH). Hence, we analyzed the 2 years outcome of SCH diagnosed during pregnancy. MATERIALS AND METHODS: We conducted this retrospective study using the medical records of patients with new onset SCH during pregnancy between 2010 and 2013 (n = 718). Patients who stopped their levothyroxine after delivery with a 2-year follow-up record were included...

OBJECTIVES/HYPOTHESIS: Thyroid cancer, with 6% to 10% of cancer diagnoses, is one of the most common malignancies during pregnancy. Its treatment poses a risk for the pregnancy, as the thyroid gland plays a crucial role in the evolution of pregnancy. The aim of this study is to evaluate treatment of primary well-differentiated thyroid carcinoma during pregnancy and fetal and maternal outcomes. STUDY DESIGN: This is an international cohort study. METHODS: Primary thyroid cancer patients were identified from the database of the International Network on Cancer, Infertility, and Pregnancy registration study...

BACKGROUND: Untreated and subclinical hypothyroidism (SCH) has been associated with adverse pregnancy complications such as increased risk of miscarriage, hypertension, preeclampsia, and preterm delivery. However, in Sweden, screening for thyroid dysfunction during pregnancy is only recommended for women with a high risk of thyroid disease. Therefore, the aim of this study was to determine the incidence of clinical and SCH in women in the first trimester of pregnancy. MATERIALS AND METHODS: In this prospective study, 1298 pregnant women were divided into three groups: one unselected general screening group (n = 611), one low-risk group comprising women without risk factors for thyroid disorder (n = 511), and one high-risk group comprising women with an inheritance or suspicion of thyroid disease or undergoing treatment for thyroid disease (n = 88)...

Exposure to triclosan (TCS), an antibacterial agent, during pregnancy is associated with hypothyroxinemia and decreases in placental glucose transporter expression and activity. The objective of this study was to investigate the influence of TCS on glucose homeostasis and insulin sensitivity in gestational mice (G-mice) and nongestational female mice (Ng-mice) as a control. Herein, we show that the exposure of G-mice to TCS (8 mg/kg) from gestational day (GD) 5 to GD17 significantly increased their levels of fasting plasma glucose and serum insulin, and insulin content in pancreatic β-cells with reduced HOMA-β index and increased HOMA-IR index...

Thyroid hormones play a pivotal role in somatic growth, metabolic regulation and neurodevelopment. There is growing evidence regarding adverse obstetric and perinatal consequences of maternal thyroid hypofunction during early stages of pregnancy. These include: early pregnancy loss, preterm delivery and lower intelligence quotient (IQ) in children. Different clinical guidelines have been published by scientific societies for the management of thyroid diseases during pregnancy and levothyroxine (LT4) has become a therapeutic agent increasingly prescribed by obstetricians...

OBJECTIVES: Selenium (Se) deficiency is related to an increased risk of preterm labor, miscarriage, preeclampsia, gestational diabetes, and other obstetric complications. As the Se status declines during pregnancy, we hypothesized that the decline may be exacerbated in women with autoimmune thyroid disease (AITD). MATERIAL AND METHODS: Pregnant women (n=74; 30 [23-38] years) were consecutively recruited from the district of Warsaw, Poland, and divided into healthy subjects (HS, n=45), and women with a diagnosis of AITD (AITD, n=29)...

This study assessed all fractures occurring in pregnancy at a tertiary referral centre over a 17-year period. Most fractures were due to minimal trauma, and those involving the ankle were the most common. Women tended to fracture during their second and third trimesters and most required surgical intervention during pregnancy. PURPOSE: To characterise fractures in pregnancy over a 17-year period at a tertiary referral health service. METHODS: Medical records at the Monash Health in Australia were examined from 2000-2016 for fractures in pregnancy using the birthing outcome system database and the tenth revision of the International Statistical Classification of Diseases and Related Health Problems coding...

Smoking is the most widespread substance dependence in the world. Nicotine and some other components of the cigarette smoke cause various endocrine imbalances, and have negative effects on pituitary, thyroid, adrenal, testicular and ovarian functions. Here, we examined studies that describe the influence of smoking and smoking cessation on the male and female reproductive systems. We also focused on studies providing an account of differences in cessation success rates between men and women. In men, the most common effects associated with smoking are erectile dysfunction and decreasing spermiogram quality...

Neonatal Graves' disease presenting as conjugated hyperbilirubinemia is a diagnostic challenge because the differential includes a gamut of liver and systemic diseases. We present a unique case of neonatal Graves' disease in a premature infant with conjugated hyperbilirubinemia born to a mother with hypothyroidism during pregnancy and remote history of Graves' disease. Infant was treated with a combination of methimazole, propranolol, and potassium iodide for 4 weeks. Thyroid function improved after 8 weeks of treatment with full recovery of thyroid function, disappearance of thyroid-stimulating antibodies, and resolution of failure to thrive and conjugated hyperbilirubinemia...

Triclosan and triclocarban (TCs) are broad-spectrum microbicides found in household and personal wash products. We sought to determine whether TC exposure from wash products or urinary triclosan level modified thyroid function during pregnancy or anthropometric measurements at birth. A randomized intervention of wash products with or without TCs, including toothpaste, enrolled pregnant women from 20 weeks' gestation. Urinary triclosan, TSH, T4 and T3 were assessed at enrollment, 36weeks' gestation and/or post-delivery; anthropometric measures at birth were ascertained from medical records...

Context: High homocysteine concentrations are associated with maternal pregnancy complications and low birth weight, jaundice and cerebrovascular accidents in neonates. Thyroid hormone may interfere with homocysteine metabolism via stimulation of vitamin B12- and folate-dependent processes and via effects on enzymes of the re-methylation pathway. Objective: Investigating the associations of maternal and neonatal thyroid function with homocysteine during pregnancy and after delivery, respectively...

Context: Resistance to thyroid hormone beta (RTHβ) is an autosomal dominant disorder characterized by reduced sensitivity of target tissues to thyroid hormones (TH). Individuals with RTHβ have high TH levels usually due to mutations in the TH receptor beta (THRB) gene. The management of RTHβ during pregnancy is challenging as wild-type (WT) fetuses born to RTHβ mothers have low birth weight and suppressed postnatal TSH, due to intrauterine exposure to excess TH. Objective: To determine birth weight and postnatal TSH of WT fetuses carried by mothers with RTHβ whose fT4 levels were maintained below 20% the upper limit of normal (ULN)...
