CONTEXT: Thyroid hormones may interfere with regulation of lipid and carbohydrate metabolism as well as with severity of nonalcoholic fatty liver disease (NAFLD), however results are still debated. OBJECTIVES: Retrospective evaluation of clinical and metabolic correlations between hypothyroidism and NAFLD was the target. METHODS: Clinical, biochemical and histological investigation of 103 NAFLD patients exhibiting drug-treated hypothyroidism was conducted. RESULTS: Steatosis was present in 32.0% of the population and nonalcoholic steatohepatitis in 68.0%. Females were the majority in both groups, with age of 50.0 ± 1.5 and 56.0 ± 1.1 years, respectively. Hypothyroidism was not rare (15.5%), and multivariate analysis confirmed positive correlation with this disease for insulin (r = 0.213, P = 0.03), glucose homeostasis index "HOMA" (r = 0.221, P = 0.02), aspartate aminotransferase (r = 0.234, P = 0.01) and triglycerides above 150 mg/dL (r = 0.233, P = 0.01). No association between hypothyroidism and steatohepatitis could be established. CONCLUSION: A link could be identified between hypothyroidism and markers of glucose and lipid homeostasis, but not with severity of NAFLD. The lack of correlation with liver biopsy requires further studies.; CONTEXTO: Os hormônios tireoidianos podem interferir na regulação do metabolismo de lipídios e carboidratos e também na gravidade da doença hepática gordurosa não-alcoólica (DHGNA)...

Introdução: O hipotireoidismo congênito possui prevalência de 1/4000 crianças nascidas vivas e pode ser causado por disgenesia tireoideana (80% dos casos) ou por defeitos de síntese hormonal (20% restantes). A disormonogênese tem sido associada a mutações nos genes: tireoglobulina, simportador sódio/iodo, tireoperoxidase, dual oxidase 2, e pendrina. A tireoglobulina é uma glicoproteína de 660KDa e funciona como matriz para a síntese dos hormônios tireoideanos. Até o momento 38 mutações inativantes, associadas a bócio e hipotireoidismo, foram identificadas no gene da tireoglobulina. Objetivos: Este estudo visou caracterizar mutações no gene da tireoglobulina em 13 pacientes brasileiros com bócio e hipotireoidismo congênito e verificar o efeito funcional da mutação A2215D identificada neste estudo. Casuística e Métodos: Foram estudados 13 pacientes com hipotireoidismo congênito por possível defeito de síntese de tireoglobulina. Foi utilizado DNA de sangue periférico de todos os pacientes e amostra de tecido da paciente portadora da mutação A2215D. Os métodos utilizados foram: amplificação e sequenciamento dos 48 exons e das junções exon/intron, transfecção de células de mamífero com plasmídeos contendo o cDNA da tireoglobulina mutada e não mutada...

Congenital hypothyroidism affects about 1:3000-1:4000 infants. Screening programs now permit early recognition and treatment, thus avoiding the disastrous consequences of thyroid hormone deficiency on brain development. In about 85%, congenital hypothyroidism is associated with developmental defects referred to as thyroid dysgenesis. They include thyroid (hemi)agenesis, ectopic tissue and thyroid hypoplasia. Thyroid dysgenesis is usually sporadic; in only 2% it occurs in a familial fashion. It can be caused by mutations in transcription factors that are essential for the development and function of thyroid follicular cells. Thyroid hypoplasia can also result from resistance to TSH at the level of the thyrocytes. Defects in the steps required for thyroid hormone synthesis within thyroid follicular cells are referred to as dyshormonogenesis and account for about 10-15% of congenital hypothyroidism. In contrast to thyroid dysgenesis, affected patients typically present with goitrous enlargement of the thyroid. The defects leading to dyshormonogenesis typically display a recessive mode of inheritance. Careful clinical, biochemical and molecular analyses of patients with syndromic and non-syndromic forms of thyroid dysgenesis and dyshormonogenesis have significantly enhanced our understanding of the wide spectrum of pathogenetic mechanisms underlying congenital hypothyroidism and provide unique insights into the (patho)physiology of thyroid development and hormone synthesis.

INTRODUCTION: Hypothyroidism has long been known for its effects on different organ systems, leading to hypometabolism. However, subclinical hypothyroidism, its most prevalent form, has been recently related to cardiovascular risk and also to maternal-fetal complications in pregnant women. OBJECTIVES: In these clinical practice guidelines, several aspects of this field have been discussed with the clear objectives of helping physicians treat patients with hypothyroidism, and of sharing some of our Latin American-based clinical experience. MATERIALS AND METHODS: The Latin American Thyroid Society commissioned a Task Force on Hypothyroidism to develop evidence-based clinical guidelines on hypothyroidism. A systematic review of the available literature, focused on the primary databases of MedLine/PubMed and Lilacs/SciELO was performed. Filters to assess methodological quality were applied to select the best quality studies. The strength of recommendation on a scale from A-D was based on the Oxford Centre for Evidence--based Medicine, Levels of Evidence 2009, allowing an unbiased opinion devoid of subjective viewpoints. The areas of interest for the studies comprised diagnosis, screening, treatment and a special section for hypothyroidism in pregnancy. RESULTS: Several questions based on diagnosis...

Objective To determine how endocrinologists in Latin America deal with clinical case scenarios related to hypothyroidism and pregnancy. Materials and methods In January 2013, we sent an electronic questionnaire on current practice relating to management of hypothyroidism in pregnancy to 856 members of the Latin American Thyroid Society (LATS) who manage pregnant patients with thyroid disease. Subsequently, we have analyzed responses from physician members. Results Two hundred and ninety-three responders represent clinicians from 13 countries. All were directly involved in the management of maternal hypothyroidism and 90.7% were endocrinologists. The recommendation of a starting dose of L-thyoxine for a woman diagnosed with overt hypothyroidism in pregnancy, preconception management of euthyroid women with known thyroid autoimmunity and approach related to ovarian hyperstimulation in women with thyroid peroxidase antibodies were widely variable. For women with known hypothyroidism, 34.6% of responders would increase L-thyroxine dose by 30-50% as soon as pregnancy is confirmed. With regard to screening...

There has been few reports on electroneuromyography (ENMG) changes in hypothyroidism. The objectives of the present study were to investigate the frequency of ENMG abnormalities in hypothyroidism and correlate them with neurological signs and symptoms and muscle enzyme levels; and to compare latency, amplitude and nerve conduction velocity from selected nerves with controls. Sixteen patients suffering from primary hypothyroidism were submitted to ENMG before treatment. ENMG abnormalities were found in 87.5% of the patients; 46.6% had myopathy and 43.7% had carpal tunnel syndrome. There was no case of polyneuropathy. A clear-cut clinical, laboratorial and ENMG correlation was observed in patients with myopathy and carpal tunnel syndrome. The patients showed a significant tendency of nerve conduction slowness as compared with controls. The findings are in accordance with the well-known nerve and muscle damage in hypothyroidism.

OBJECTIVE: The treatment of the chronic hepatitis C (HCV) with α-interferon is associated with thyroid dysfunction (TD). The aim of this study was to evaluate thyroid function outcome among patients with chronic HCV under treatment with conventional interferon (IFN) or peguilated interferon (PEG-IFN) in association with ribavirin. PATIENTS AND METHODS: We studied 293 patients with chronic HCV, submitted to drug therapy for 24 or 48 weeks. Initially, we evaluated FT4, TSH, TPOAb, TgAb, and continued to monitor FT4 and TSH every three months during therapy and six months thereafter. RESULTS: At baseline, TD prevalence was 6.82% (n = 20); 6.14% hypothyroidism; 0.68% hyperthyroidism. TPOAb was present in 5.46% of euthyroid patients. Out of 273 euthyroid patients at baseline, 19% developed TD: 17.2% hypothyroidism; 1.8% hyperthyroidism; 5.1% destructive thyroiditis (DT). 90% of TPOAb-positive patients at baseline developed hypothyroidism vs 14.5% of TPOAb-negative patients (p < 0.001). On average, TD occurred after 25.8 ± 15.5 weeks of treatment. 87.2% of patients who developed hypothyroidism did so during the first therapeutic cycle (p = 0.004; OR = 3.52; 95% CI = 1.36-9.65). Patients infected with genotype 1 virus were 2.13 times more likely to develop hypothyroidism (p = 0.036; 95% CI = 1.04-4.38). Hypothyroid and DT patients presented higher TSH levels before-treatment than patients who had remained euthyroid (p < 0.001; p = 0.002...

BACKGROUND: Previous studies have suggested an association between subclinical hypothyroidism and coronary artery disease that could be related to changes in serum lipids or endothelial dysfunction. METHODS: Thirty-two female subclinical hypothyroidism patients were randomly assigned to 12 months of L-thyroxine replacement or no treatment. Endothelial function was measured by the flow-mediated vasodilatation of the brachial artery, as well as mean carotid artery intima-media thickness, and lipid profiles were studied at baseline and after 12 months of follow-up. RESULTS: The mean ( ± SD) serum thyroid-stimulating hormone levels in the L-thyroxine replacement and control groups were 6.09±1.32 and 6.27 ± 1.39 μUI/ml, respectively. No relationship between carotid artery intima-media thickness or brachial flow-mediated vasodilatation and free T4 and serum thyroid-stimulating hormone was found. The median L-T4 dose was 44.23 ± 18.13 μg/day. After 12 months, there was a significant decrease in the flow-mediated vasodilatation in the subclinical hypothyroidism control group (before: 17.33 ± 7.88 to after: 13.1 ±4.75%, p =0.03), but there were no significant differences in flow-mediated vasodilatation in the L-thyroxine treated group (before: 16.81 ± 7.0 to after: 18.52 ± 7.44%...

Objective Our objective in this study was to determine the relationship between irisin hormone, which has a similar effect with thyroid hormones on adipose tissue and the metabolism, and the thyroid functions and the obesity secondary to thyroid disease. Subjects and methods Seventy-four patients were included in the study, of the patients, 37 were newly diagnosed with Hashimoto’s thyroiditis related hypothyroidism but not started on a treatment yet, and the remaining 37 were healthy volunteers without a known disease. Serum thyroid stimulating hormone (TSH), free thyroxin (fT4), anti-thyroglobulin and anti-thyroid peroxidase were measured and thyroid ultrasonography was performed in both groups. Serum irisin levels were measured using the commercially available ELISA kit. The hypothyroidism group had higher levels of irisin compared to the control group (2.77 ng/mL vs. 2.15 ng/mL respectively; p = 0.017). Results The hypothyroidism group had higher median levels of irisin in the obese patients than those in the control group (3.10 ng/mL vs. 2.10 ng/mL respectively; p = 0.013). Irisin level was negatively correlated with age in the whole population and patients with hypothyroidism (r = -0.255, p = 0.028; r = -0.346, p = 0.036 respectively). Irisin level was positively correlated with TSH (r = 0.247...

Mutations in the NK2 homeobox 1 gene (NKX2-1) cause a rare syndrome known as choreoathetosis, congenital hypothyroidism, and neonatal respiratory distress syndrome (OMIM 610978). Here we present the first reported patient with this condition caused by a 14q13.3 deletion which is adjacent to but does not interrupt NKX2-1, and review the literature on this condition. The infant presented at 23 months with a history of developmental delay, hyperkinesia, recurrent respiratory infections, neonatal respiratory distress, and hypothyroidism. Choreiform movements and delayed motor milestones were first noted at 6-8 months of age. TSH levels had been consistently elevated from 8 months of age. The clinical presentation was suggestive of an NKX2-1 mutation. Sequencing of all exons and splice site junctions of NKX2-1 was performed but was normal. Array CGH was then performed and a 3.29 Mb interstitial deletion at 14q13.1-q13.3 was detected. The distal region of loss of the deletion disrupted the surfactant associated 3 (SFTA3) gene but did disrupt NKX2-1. Findings were confirmed on high resolution SNP array and multiplex semiquanitative PCR. NKX2-1 encodes transcriptional factors involved in the developmental pathways for thyroid, lung, and brain. We hypothesize that the region centromeric to NKX2-1 is important for the normal functioning of this gene and when interrupted produces a phenotype that is typical of the choreoathetosis...

AbstractObjective:To establish benchmarks and study some sonographic characteristics of the thyroid gland in a group of euthyroid children aged up to 5 years as compared with age-matched children with congenital hypothyroidism.Materials and Methods:Thirty-six children (17 female and 19 male) aged between 2 months and 5 years were divided into two groups – 23 euthyroid children and 13 children with congenital hypothyroidism – and were called to undergo ultrasonography.Results:In the group of euthyroid children (n = 23), mean total volume of the thyroid gland was 1.12 mL (minimum, 0.39 mL; maximum, 2.72 mL); a homogeneous gland was found in 17 children (73.91%) and 6 children (26.08%) had a heterogeneous gland. In the group of children with congenital hypothyroidism (n = 13), mean total volume of the thyroid gland was 2.73 mL (minimum, 0.20 mL; maximum, 11.00 mL). As regards thyroid location, 3 patients (23.07%) had ectopic thyroid, and 10 (69.23%) had topic thyroid, and out of the latter, 5 had a homogeneous gland (50%) and 5, a heterogeneous gland (50%). In the group with congenital hypothyroidism, 6 (46.15%) children had etiological diagnosis of dyshormoniogenesis, 3 (23.07%), of ectopic thyroid, and 4 (30.76%), of thyroid hypoplasia.Conclusion:Thyroid ultrasonography is a noninvasive imaging method...

BACKGROUND Over the last decade there has been enhanced awareness of the appreciable morbidity of thyroid dysfunction, particularly thyroid deficiency. Since treating clinical and subclinical hypothyroidism may reduce adverse obstetric outcomes, it is crucial to identify which interventions are safe and effective. OBJECTIVES To identify interventions used in the management of hypothyroidism and subclinical hypothyroidism pre-pregnancy or during pregnancy and to ascertain the impact of these interventions on important maternal, fetal, neonatal and childhood outcomes. SEARCH METHODS We searched the Cochrane Pregnancy and Childbirth Group’s Trials Register (31 March 2013). SELECTION CRITERIA Randomised controlled trials (RCTs) and quasi-randomised controlled trials that compared a pharmacological intervention for hypothyroidism and subclinical hypothyroidism pre-pregnancy or during pregnancy with another intervention or placebo. DATA COLLECTION AND ANALYSIS Two review authors assessed trial eligibility and quality and extracted the data. MAIN RESULTS We included four RCTs of moderate risk of bias involving 362 women. In one trial of 115 women, levothyroxine therapy to treat pregnant euthyroid (normal thyroid function) women with thyroid peroxidase antibodies was not shown to reduce pre-eclampsia significantly (risk ratio (RR) 0.61; 95% confidence interval (CI) 0.11 to 3.48) but did significantly reduce preterm birth by 72% (RR 0.28; 95% CI 0.10 to 0.80). Two trials of 30 and 48 hypothyroid women respectively compared levothyroxine doses...

TEMA: o hipotireoidismo congênito é uma alteração metabólica que traz conseqüência graves para indivíduos não tratados e mesmo as crianças que realizam o tratamento podem apresentar distúrbios do desenvolvimento. O Programa Nacional de Triagem Neonatal, instituído pelo Ministério da Saúde, prevê o acompanhamento longitudinal de indivíduos com equipe multidisciplinar. Entretanto, a Fonoaudiologia não é incluída nesta equipe. Deste modo, considerando a ocorrência de distúrbios da comunicação nestes indivíduos, realizou-se levantamento bibliográfico nas bases de dados Lilacs, MedLine e PubMed, no período de 1987 a 2007, referente às alterações em habilidades do desenvolvimento decorrentes do hipotireoidismo congênito. OBJETIVO: verificar, na literatura científica, presença de alterações do desenvolvimento em indivíduos com hipotireoidismo congênito e refletir sobre a importância da atuação fonoaudiológica, em conjunto com equipe multidisciplinar especializada, no acompanhamento dos mesmos. CONCLUSÃO: a literatura relata alterações nas habilidades do desenvolvimento (motoras, cognitivas, lingüísticas e de autocuidados) e destaca que crianças com hipotireoidismo congênito são de risco para alterações no desenvolvimento lingüístico e...

A tireoide é uma glândula endócrina responsável pela produção de hormônios e sua função é sintetizar os hormônios tireoidianos essenciais para o desenvolvimento e crescimento de diversos órgãos e sistemas em humanos, desde a vida intra-uterina até o segundo ano de vida. A diminuição na produção ou ausência de hormônios tireoidianos leva à patologia denominada hipotireoidismo e quando essa alteração está presente desde o nascimento, denomina-se hipotireoidismo congênito. Nesses casos, a literatura aponta que crianças com hipotireoidismo congênito podem apresentar, entre várias alterações, dificuldades nas habilidades motoras finas e no desenvolvimento da linguagem. O objetivo geral do estudo foi avaliar as habilidades motoras finas e da função expressiva da linguagem de crianças com hipotireoidismo congênito, e investigar se há associação entre habilidades motoras finas e função expressiva da linguagem. Trata-se de um estudo prospectivo de uma coorte de crianças com hipotireoidismo congênito, diagnosticadas e acompanhadas em um serviço de referência em triagem neonatal de um hospital público e de crianças sem essa disfunção. A triagem foi realizada por meio das Escalas Bayley de Desenvolvimento Infantil III...

OBJECTIVE: To evaluate the prevalence of psychiatric disorders and symptoms in patients with subclinical hypothyroidism. METHOD: Ninety-four outpatients with at least two elevated serum thyrotrophin levels (> 4 µU/ml) and normal FT4, and 43 euthyroid outpatients, both groups from HUCFF-UFRJ, were evaluated. Psychiatric diagnosis was based on the Structured Clinical Interview Diagnostic for the DSM-IV axis I (SCID-I/DSM-IV), the psychopathological symptoms on Hamilton anxiety and depression scales, and the Beck Inventory. RESULTS: Our data showed an increased prevalence of psychiatric disorders in the subclinical hypothyroidism patients when compared to the euthyroid group (45.7% vs 25.6%; p = 0.025), mood disorders being the most frequent. The prevalence of depressive symptoms based on Beck's Scale among subclinical hypothyroidism patients was about 2.3 times higher than among euthyroid ones (45.6% vs 20.9%, p = 0.006). Anxiety symptoms were also more frequent among subclinical hypothyroidism patients (87.0% vs 60.5%, p < 0.001), mainly clinical anxiety (44.6% vs 23.3%; p = 0.001). CONCLUSION: Our results showed a significant association of subclinical hypothyroidism with psychiatric disorders and an increased frequency of subsyndromic depression and anxiety symptoms in subclinical hypothyroidism in relation to the euthyroid group.

Artículo de publicación ISI; Introduction: Hypothyroidism has long been known for its effects on different organ systems, leading to hypometabolism. However, subclinical hypothyroidism, its most prevalent form, has been recently related to cardiovascular risk and also to maternal-fetal complications in pregnant women. Objectives: In these clinical practice guidelines, several aspects of this field have been discussed with the clear objectives of helping physicians treat patients with hypothyroidism, and of sharing some of our Latin American-based clinical experience. Materials and methods: The Latin American Thyroid Society commissioned a Task Force on Hypothyroidism to develop evidence-based clinical guidelines on hypothyroidism. A systematic review of the available literature, focused on the primary databases of MedLine/PubMed and Lilacs/SciELO was performed. Filters to assess methodological quality were applied to select the best quality studies. The strength of recommendation on a scale from A-D was based on the Oxford Centre for Evidence- -based Medicine, Levels of Evidence 2009, allowing an unbiased opinion devoid of subjective viewpoints. The areas of interest for the studies comprised diagnosis, screening, treatment and a special section for hypothyroidism in pregnancy. Results: Several questions based on diagnosis...

BACKGROUND: Previous studies have suggested an association between subclinical hypothyroidism and coronary artery disease that could be related to changes in serum lipids or endothelial dysfunction. METHODS: Thirty-two female subclinical hypothyroidism patients were randomly assigned to 12 months of L-thyroxine replacement or no treatment. Endothelial function was measured by the flow-mediated vasodilatation of the brachial artery, as well as mean carotid artery intima-media thickness, and lipid profiles were studied at baseline and after 12 months of follow-up. RESULTS: The mean ( ± SD) serum thyroid-stimulating hormone levels in the L-thyroxine replacement and control groups were 6.09±1.32 and 6.27 ± 1.39 μUI/ml, respectively. No relationship between carotid artery intima-media thickness or brachial flow-mediated vasodilatation and free T4 and serum thyroid-stimulating hormone was found. The median L-T4 dose was 44.23 ± 18.13 μg/day. After 12 months, there was a significant decrease in the flow-mediated vasodilatation in the subclinical hypothyroidism control group (before: 17.33 ± 7.88 to after: 13.1 ±4.75%, p =0.03), but there were no significant differences in flow-mediated vasodilatation in the L-thyroxine treated group (before: 16.81 ± 7.0 to after: 18.52 ± 7.44%...
