hypothyroidism guidelines

Hypothyroidism is a relatively common finding during pregnancy. This may be due either to the presence of existing thyroid disease and/or to the increased demands that pregnancy places the thyroid gland to provide thyroid hormones for the mother and the developing fetus. There is no doubt that overt hypothyroidism is associated strongly with adverse pregnancy outcomes, including miscarriage. Meta-analyses show that thyroid hormone replacement with levothyroxine (LT4) reduces the risk of adverse pregnancy outcomes in the setting of overt hypothyroidism...

Hypothyroidism is characterized by thyroid hormone deficiency and has adverse effects on both pregnancy and fetal health. Chat Generative Pre-trained Transformer (ChatGPT) is a large language model trained with a very large database from many sources. Our study was aimed to evaluate the reliability and readability of ChatGPT-4 answers about hypothyroidism in pregnancy. A total of 19 questions were created in line with the recommendations in the latest guideline of the American Thyroid Association (ATA) on hypothyroidism in pregnancy and were asked to ChatGPT-4...

There is controversy regarding whether to treat subtle abnormalities of thyroid function in infertile female patients. This guideline document reviews the risks and benefits of treating subclinical hypothyroidism in female patients with a history of infertility and miscarriage, as well as obstetric and neonatal outcomes in this population.

Lipid disorders are common in several endocrine conditions. Diabetes mellitus, hypothyroidism and Cushing's syndrome are the common endocrine disorders with dyslipidemia. Dyslipidemia has a significant impact on endocrine and metabolic health and the risk of atherosclerotic cardiovascular disease. In most cases of dyslipidemia, the suspicion of endocrine diseases must be based on clinical symptoms and signs. Optimal management of the dyslipidemia requires treatment of the underlying endocrine condition. Lipid lowering therapy is a useful adjunct or a requirement in many cases...

OBJECTIVE: To investigate general practitioners' course of action after detection of elevated thyroid stimulating hormone (TSH) levels regarding repeat testing, direct levothyroxine replacement, or neither. METHODS: We conducted a retrospective study of adults without prior evidence of thyroid disease and with a first detection of elevated TSH levels from January 1, 2015, to December 31, 2020, using data from electronic medical records of a Swiss primary care database...

Background Thyroid hormone replacement (THR) in athyreotic patients post-thyroidectomy due to thyroid cancer might seem like a straightforward clinical issue to address. To investigate the impact of THR on enhancing thyroid-stimulating hormone (TSH) levels, we conducted a clinical audit, tailoring the dosage based on patient weight and aligning with the standards outlined by the National Institute for Health and Care Excellence and the American Thyroid Association guidelines. Methodology This retrospective and prospective audit analyzed outpatient clinic records for hormone replacement therapy (HRT) post-total thyroidectomy...

A 7-year-old boy with a history of pleuropulmonary blastoma after resection 6 years prior and germline DICER1 mutation was being monitored by physicians at a multidisciplinary genetic predisposition clinic. He demonstrated no evidence of recurrent pleuropulmonary blastoma, and his renal US, chest radiographic, and ocular screening examination results remained normal. Per age-directed screening guidelines, he underwent thyroid US. He had no signs or symptoms of hyper- or hypothyroidism. Physical examination was notable for the absence of thyromegaly or palpable nodule...

BACKGROUND: Cronkhite-Canada syndrome (CCS) is a rare sporadic polyposis syndrome that presents with gastrointestinal and ectodermal symptoms in addition to nutritional deficiencies. CCS combined with hypothyroidism is an even rarer condition, with no standard treatment guidelines. CASE SUMMARY: The present study described 2 patients with CCS: A 67-year-old woman with concomitant hypothyroidism and 68-year-old man treated with endoscopic mucosal resection (EMR)...

Relapsing polychondritis (RP) is a rare autoimmune condition that involves the recurrent inflammation of cartilage throughout the body, with a predilection for auricular and nasal cartilage. Given its rarity and diverse clinical presentations, RP is frequently misdiagnosed or left untreated, which can lead to significant morbidity and mortality. When it is correctly diagnosed, there are no standardized guidelines on the treatment of RP to date. Management of this disease requires a multidisciplinary approach, and about 30% of patients with RP have other autoimmune disorders, further complicating the approach to targeted treatment...

INTRODUCTION: Current guidelines recommendations for the initial dose of prednisolone (PSL) in the treatment of subacute thyroiditis (SAT) are based on low-quality studies. We designed a randomized controlled trial (RCT) to compare the efficacy and safety of using a low initial dose of PSL with a standard initial dose of PSL in SAT patients. PATIENTS AND METHODS: This open-label RCT was conducted at five hospitals in China from June 2019 to January 2022. SAT patients with moderate-to-severe pain or a poor response to non-steroidal anti-inflammatory drugs (NSAIDs) were randomly assigned in a 1:1 ratio to the experimental and control groups...

Introduction There is considerable evidence to suggest the role of thyroid hormone in acute coronary syndrome (ACS), but less is known about its prognostic role in heart failure (HF). We aimed to assess the role of global longitudinal strain (GLS) in patients hospitalized with HF and underlying subclinical hypothyroidism (SCHS). Methods A retrospective analysis of 161 subjects was conducted by dichotomizing them into HF with preserved ejection fraction (HFpEF) and HF with reduced ejection fraction (HFrEF) subgroups...

BACKGROUND: Gestational hypothyroidism has been shown to be associated with adverse pregnancy outcomes as well as adverse outcomes for the child. Thyroid hormones concentrations change in gestation, especially within the first trimester, so the results of thyroid function test often are outside non-pregnant reference ranges. The objective of this study was to establish the first trimester reference ranges for thyroid stimulating hormone (TSH) and free thyroxine (FT4) for pregnant women in Barcelona (Spain)...

Olfactory neuroblastomas, or esthesioneuroblastomas, are rare and aggressive malignant tumors that typically arise from the olfactory neuroepithelium in the upper nasal cavity. In rare instances, they can be ectopic originating from areas outside the upper nasal cavity such as the sellar region. These tumors, also known as primary sellar neuroblastomas, may be mistaken for pituitary macroadenomas. We present a rare case of a primary sellar neuroblastoma in a 30-year-old woman with a prior diagnosis of presumed prolactinoma, status post transsphenoidal resection, with residual visual deficits, who presented with worsening vision and headaches...

The onset of pregnancy places additional stress of the thyroid gland, which must produce additional thyroid hormones to support the developing foetus. Hypothyroidism, including subclinical hypothyroidism (SCH), may appear de novo at this time, or existing thyroid disease may become more severe. Accordingly, SCH is a relatively common complication of up to about 3% of pregnancies, with higher rates in some areas. There is strong evidence from systematic reviews and meta-analyses that uncontrolled SCH is associated with an increased risk of adverse pregnancy outcomes, including miscarriage, preeclampsia, and gestational diabetes...

AIMS AND OBJECTIVES: Oncological surgery of the upper aerodigestive tract is a complex procedure and often includes neck dissection and flap reconstruction. It can be complicated by severe surgical site infection (SSI) leading to flap necrosis, delayed wound healing, and increasing mortality and morbidity. The purpose of this study is to perform a systematic descriptive analysis and to evaluate the effect of our adapted antibiotic regimen strategy on postoperative outcomes. MATERIALS AND METHODS: A prospective cohort analysis of 47 patients undergoing major clean-contaminated head and neck surgery was conducted at the Cervicomaxillofacial Surgery Department (Saint-Pierre Hospital), between 2019 and 2022...

BACKGROUND: Free T4 (FT4) determination is one of the most commonly performed biochemical tests in endocrinology. Treatment of thyroid dysfunctions is adjusted based on the severity of symptoms and biochemical test results. For Graves' hyperthyroidism, clinical guidelines recommend using FT4 as a (rough) guide to dose antithyroid drugs, together with other clinical information. It is well known that different platforms and methods give different FT4 results; however, large non-linear method differences at high FT4 concentrations are less well recognized...

Guidelines for screening and management of congenital hypothyroidism in neonates have been recently updated by the American Academy of Pediatrics (AAP). This article compares new AAP guideline with the Indian Society for Pediatric and Adolescent Endocrinology (ISPAE) Guidelines, 2018 and lists the changes in screening, diagnosis, and management of congenital hypothyroidism suggested in the new guidelines, along with clinical utilization in the Indian scenario.

BACKGROUND: Although subclinical hypothyroidism (SCH) is related to abnormalities in left ventricular diastolic function, the use of levothyroxine as a regular treatment remains debatable. This meta-analysis aimed to determine whether thyroid hormone replacement therapy affects cardiac diastolic function in patients with SCH as measured by echocardiography. METHODS: This meta-analysis included a search of the EMBASE, PubMed, Web of Science, and Cochrane Library databases from their inception to May 18, 2023, for studies analyzing cardiac morphology and functional changes in patients with SCH before and after thyroid hormone replacement...

Diabetes mellitus (DM) and thyroid dysfunction are two disorders that are closely related. This systematic review aimed to investigate the effect of levothyroxine supplementation on diabetic nephropathy in type 2 diabetic patients with co-existing thyroid dysfunction. We explored medical databases such as PubMed, Medline, Multidisciplinary Digital Publishing Institute (MDPI), and Cochrane Library for relevant medical literature. The papers were screened, and 12 research papers involving 10,371 patients were identified after applying eligibility criteria and quality assessment using Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines...

Levothyroxine (LT) is the synthetic form of thyroxine (T4), a thyroid hormone analog used to treat hypothyroidism. LT overdose rarely results in severely poor outcomes. General guidelines for treating exogenous thyrotoxicosis depend on the severity of symptoms. There is no standardized protocol; however, drug discontinuation, beta-blockers (specifically propranolol), and cholestyramine effectively manage overdose when needed, with most cases resolving independently without medical intervention.  Here, we present the case of a 26-year-old female with a history of supraventricular tachycardia, anxiety, depression, and Hashimoto thyroiditis who was accidentally overprescribed LT (300 mcg for one and a half months) that resulted in symptoms of lethargy, tremors, body temperature dysregulation, orthostatic hypotension, and diarrhea...
