[Treatment of Graves' disease is moving towards precision medicine]. / Behandling av Graves sjukdom.

This is the first national guideline in hyperthyroidism to harmonise and update clinical practice according to what is evidence based and direct care from patients' needs. We present 4 articles in Läkartidningen of different views of the guideline, including family care perspectives, patient care perspectives and perspectives on ophthalmology. This article concerns treatment of Graves' disease and includes endocrinological, surgical and oncological perspectives on what is established practice, but also news in the national guideline that remain to be fully implemented in Sweden in the years to come. News are precision medicine using the GREAT score, preoperative calcium/D vitamin treatment, individualized levothyroxine treatment after thyroid surgery, uniformed levothyroxine replacement strategy, access to national patient information and national guidelines on radiation protection and treatment schemes for radioactive iodine. A national guideline is the creation of many persons' views, including patient representatives, and the recommendations have undergone a thorough national review process from stakeholders. It is a guideline with future perspectives for an improved care.

GRADE-ADOLOPMENT of hyperthyroidism treatment guidelines for a Pakistani context.

INTRODUCTION: The prevalence of hyperthyroidism in Pakistan is 2.9%, which is two times higher than in the United States. Most high-quality hyperthyroidism clinical practice guidelines (CPGs) used internationally originate from high-income countries in the West. Local CPGs in Pakistan are not backed by transparent methodologies. We aimed to produce comprehensive, high-quality CPGs for the management of hyperthyroidism in Pakistan. METHODS: We employed the GRADE-ADOLOPMENT approach utilizing the 2016 American Thyroid Association Guidelines for Diagnosis and Management of Hyperthyroidism and Other Causes of Thyrotoxicosis as the source CPG. Recommendations from the source guideline were either adopted as is, excluded, or adapted according to our local context. RESULTS: The source guideline included a total of 124 recommendations, out of which 71 were adopted and 49 were excluded. 4 recommendations were carried forward for adaptation via the ETD process, with modifications being made to 2 of these. The first addressed the need for liver function tests (LFTs) amongst patients experiencing symptoms of hepatotoxicity while being treated with anti-thyroid drugs (ATDs). The second pertained to thyroid status testing post-treatment by radioactive iodine (RAI) therapy for Graves' Disease (GD). Both adaptations centered around the judicious use of laboratory investigations to reduce costs of hyperthyroidism management. CONCLUSION: Our newly developed hyperthyroidism CPGs for Pakistan contain two context-specific modifications that prioritize patients' finances during the course of hyperthyroidism management and to limit the overuse of laboratory testing in a resource-constrained setting. Future research must investigate the cost-effectiveness and risk-benefit ratio of these modified recommendations.

An unusual evolution of thyroid function after therapeutic plasma exchange in Graves' disease with cholestatic jaundice: A case report.

RATIONALE: Methimazole (MMI) is the first-line agent in the treatment of hyperthyroidism. However, rare but severe cholestatic jaundice may occur. Therapeutic plasma exchange (TPE) may provide an alternative treatment for such patients and they received thyroidectomy/radioactive iodine ablation or continued oral anti hyperthyroidism medication immediately after TPE session in the reported literatures. The case reported here is, to our knowledge, the first to describe the long interval between anti hyperthyroidism therapy and TPE in such patients. PATIENT CONCERNS: A 49-year-old Chinese woman had developed worsening jaundice 3 weeks after receiving methimazole (20 mg/day) for the treatment of hyperthyroidism secondary to Graves' disease (GD). Additionally, she had a 2-year history of type 2 diabetes. DIAGNOSIS: Hyperthyroidism secondary to GD, MMI-induced severe cholestatic jaundice and type 2 diabetes. INTERVENTIONS: Methimazole was discontinued and the patient received 3 times of TPE, about 3-month glucocorticoid treatment, insulin administration accordingly and other conventional liver-protecting therapy. OUTCOMES: Her thyroid function was stabilized with small dose of thyroxine substitution and euthyroid status persisted after thyroxine discontinuation until hyperthyroidism recurred 7 months later while her cholestatic jaundice was eventually recovered by about 3-month glucocorticoid therapy. LESSONS: Due to the complex interplay between liver function and thyroid hormones, there may be unusual changes of thyroid function in GD patients with severe liver injury after TPE. By this case, we want to highlight the importance of a closely following up of thyroid function in order to deliver appropriate health suggestions for patients.

Hyperthyroidism.

Thyrotoxicosis causes a variety of symptoms and adverse health outcomes. Hyperthyroidism refers to increased thyroid hormone synthesis and secretion, most commonly from Graves' disease or toxic nodular goitre, whereas thyroiditis (typically autoimmune, viral, or drug induced) causes thyrotoxicosis without hyperthyroidism. The diagnosis is based on suppressed serum concentrations of thyroid-stimulating hormone (TSH), accompanied by free thyroxine and total or free tri-iodothyronine concentrations, which are raised (overt hyperthyroidism) or within range (subclinical hyperthyroidism). The underlying cause is determined by clinical assessment, detection of TSH-receptor antibodies and, if necessary, radionuclide thyroid scintigraphy. Treatment options for hyperthyroidism include antithyroid drugs, radioactive iodine, and thyroidectomy, whereas thyroiditis is managed symptomatically or with glucocorticoid therapy. In Graves' disease, first-line treatment is a 12-18-month course of antithyroid drugs, whereas for goitre, radioactive iodine or surgery are preferred for toxic nodules or goitres. Evidence also supports long-term treatment with antithyroid drugs as an option for patients with Graves' disease and toxic nodular goitre.

Hyperthyroidism: A Review.

Importance: Overt hyperthyroidism, defined as suppressed thyrotropin (previously thyroid-stimulating hormone) and high concentration of triiodothyronine (T3) and/or free thyroxine (FT4), affects approximately 0.2% to 1.4% of people worldwide. Subclinical hyperthyroidism, defined as low concentrations of thyrotropin and normal concentrations of T3 and FT4, affects approximately 0.7% to 1.4% of people worldwide. Untreated hyperthyroidism can cause cardiac arrhythmias, heart failure, osteoporosis, and adverse pregnancy outcomes. It may lead to unintentional weight loss and is associated with increased mortality. Observations: The most common cause of hyperthyroidism is Graves disease, with a global prevalence of 2% in women and 0.5% in men. Other causes of hyperthyroidism and thyrotoxicosis include toxic nodules and the thyrotoxic phase of thyroiditis. Common symptoms of thyrotoxicosis include anxiety, insomnia, palpitations, unintentional weight loss, diarrhea, and heat intolerance. Patients with Graves disease may have a diffusely enlarged thyroid gland, stare, or exophthalmos on examination. Patients with toxic nodules (ie, in which thyroid nodules develop autonomous function) may have symptoms from local compression of structures in the neck by the thyroid gland, such as dysphagia, orthopnea, or voice changes. Etiology can typically be established based on clinical presentation, thyroid function tests, and thyrotropin-receptor antibody status. Thyroid scintigraphy is recommended if thyroid nodules are present or the etiology is unclear. Thyrotoxicosis from thyroiditis may be observed if symptomatic or treated with supportive care. Treatment options for overt hyperthyroidism from autonomous thyroid nodules or Graves disease include antithyroid drugs, radioactive iodine ablation, and surgery. Treatment for subclinical hyperthyroidism is recommended for patients at highest risk of osteoporosis and cardiovascular disease, such as those older than 65 years or with persistent serum thyrotropin level less than 0.1 mIU/L. Conclusions and Relevance: Hyperthyroidism affects 2.5% of adults worldwide and is associated with osteoporosis, heart disease, and increased mortality. First-line treatments are antithyroid drugs, thyroid surgery, and radioactive iodine treatment. Treatment choices should be individualized and patient centered.

The management of pediatric Graves' disease.

PURPOSE OF REVIEW: Graves' disease (GD) constitutes a significant proportion of thyroid disorders seen during childhood. Several specialties may be closely involved in the management of pediatric patients with GD and emerging research in each field contributes to variations in the approach over time. Here we review the recent literature on the management of the disease, with the hope that this can be a valuable resource for treating specialists who need to be continuously updated on new data obtained in relevant fields. RECENT FINDINGS: Genetic, postinfectious and environmental factors may play a role in the immunological pathophysiology of GD. Research performed during the COVID-19 pandemic supports that viral-induced immune dysregulation may be a possible trigger for the disease. The various current treatment options all have positive and negative factors to consider. Antithyroidal drug therapy (ATD) is generally recommended as the initial treatment, although remission rates are only 20-30% at 2 years and 75% at 9 years. Unfortunately, about half of patients will relapse within 1 year of discontinuing therapy. Radioactive iodine therapy (RAI) is an effective treatment option and can be considered in certain pediatric patients. There continues to be no definitive evidence that the doses used for GD lead to a higher risk of cancer. Surgical treatment via thyroidectomy is effective and safe when performed by a high-volume surgeon. Recent studies show improvement in quality-of-life after surgery in adolescents and young adults. Future medical treatment options for GD currently being studied include antigen-specific immunotherapy and monoclonal antibodies. SUMMARY: Although the future holds promising new therapeutic options for autoimmune diseases including GD, the current choices continue to be ATD, usually first-line, and definitive treatments including RAI and surgery. While all three offer the possibility of remission or cure, drug therapy and RAI have a possibility of relapse. Risks of each approach should be broached in detail with patients and their families, and the nuances of treating this disease specifically in children should be familiar to all treating providers.

Evaluation of the diagnostic performance of thyroid-stimulating immunoglobulin and thyrotropin receptor antibodies for Graves' disease.

OBJECTIVE: To evaluate thyroid-stimulating immunoglobulin (TSI) and thyrotropin receptor antibodies (TRAb) diagnostic performance for Graves' disease (GD) and determine clinical cut-off value for diagnosing GD. METHODS: Of 1369 retrospectively enrolled subjects, 1364 had a definitive diagnosis of untreated GD (GD-UT, n = 87); treated GD (GD-T, n = 206); autoimmune thyroid disease (AIT, n = 241); thyroid nodules (TN, n = 677); subacute thyroiditis (ST, n = 28); healthy subjects (HS, n = 125); other diseases with serological hyperthyroidism (n = 5) and were grouped into the following: UT-GD and control groups (AIT, TN, ST, and HS); and UT-GD and non-GD hyperthyroidism groups. Diagnostic performance of TSI and TRAb was evaluated using area under the curve (AUC) of receiver-operating characteristic (ROC) curve, and optimal clinical cut-off value was determined using maximization of Youden index. RESULTS: TRAb AUC and clinical cut-off value for diagnosing GD were 0.981 and 1.245 IU/L (sensitivity, 96.6%; specificity, 97.1%; positive predictive value [PPV], 71.8%; negative predictive value [NPV], 99.9%; positive likelihood ratio [PLR], 33.31; negative likelihood ratio [NLR, 0.035), respectively, for the GD-UT and control groups. Those for TSI were 0.992 and 0.467 IU/L (sensitivity 98.8%; specificity, 96.4%; PPV, 68.8%; NPV, 99.9%; PLR, 27.472; NLR, 0.011). Those for TRAb in GD-UT and non-GD hyperthyroidism groups were 0.923 and 1.78 IU/L (sensitivity, 92.0%; specificity, 89.1%; PPV, 93%; NPV, 87.5%; PLR, 8.44; NLR, 0.089), respectively. For TSI, these were 0.92 and 0.545 IU/L (sensitivity, 97.7%; specificity, 83.6%; PPV, 90.4%; NPV, 95.8%; PLR27.472, NLR, 0.011), respectively. CONCLUSION: TSI diagnostic performance for GD was excellent and had better sensitivity than TRAb.

The characteristics of Grave's disease in children and adolescent patients in Al-Madinah Al-Munawwarah: A retrospective chart review.

OBJECTIVES: To determine the characteristics of Graves' disease in children and adolescents in Medina, the Kingdom of Saudi Arabia, and compare them to those observed in other countries. METHODS: This is a retrospective chart review of children and adolescents diagnosed with Graves' disease between January 2010 and May 2021. RESULTS: Fifty-eight patients aged 12.02 ± 4.85 years were identified, of which 44 (75.9%) were females. Exophthalmos (63.8%), neck swelling (60.3%), palpitations (46.6%), and tremors (29.3%) were the most common manifestations. Vitiligo (1.72%) and alopecia (1.72%) were the only autoimmune diseases observed in our patients. The median (IQR) value was 0.01 (0.36) (ulU/mL) for thyroid-stimulating hormone (TSH) and 24.89 (29.50) (pmol/L) for FT4. In terms of treatment modalities, 55 (94.8%) received antithyroid medication, 6 (10.3%) underwent thyroidectomy and one patient (1.72%) was treated with radioactive iodine. CONCLUSION: In general, Graves' disease is more common in females. Neck swelling, palpitation, and tremors were the main manifestations. Compared with other countries, there was a higher frequency of exophthalmos and a lower frequency of associated autoimmune conditions. The primary treatment was antithyroid drugs; thyroidectomy and radioactive iodine were used less frequently.

Patient needs and care: moves toward person-centered care for Graves' disease in Sweden.

Patients with Graves' disease (GD) not only need appropriate medical care, but they also need to be cared for. The aim of this review is to examine the literature on GD patient needs, expectations, perceptions, and quality of life. We will also present methods for patient care, define gaps in knowledge, and suggest factors that can be introduced into the regular care of GD patients. Patient information, teamwork with thyroid/contact nurses, education of personnel and patients, quality of life measurements, and the formation of a rehabilitation program have enough evidence to be implemented into regular care. However, visualizing patient needs through person-centered care requires further evaluation in GD patients before being implemented in routine care. We conclude that considerable improvement in nursing can be achieved in relation to GD.

Hyperthyroidism: aetiology, pathogenesis, diagnosis, management, complications, and prognosis.

Hyperthyroidism is a common condition with a global prevalence of 0·2-1·3%. When clinical suspicion of hyperthyroidism arises, it should be confirmed by biochemical tests (eg, low TSH, high free thyroxine [FT4], or high free tri-iodothyonine [FT3]). If hyperthyroidism is confirmed by biochemical tests, a nosological diagnosis should be done to find out which disease is causing the hyperthyroidism. Helpful tools are TSH-receptor antibodies, thyroid peroxidase antibodies, thyroid ultrasonography, and scintigraphy. Hyperthyroidism is mostly caused by Graves' hyperthyroidism (70%) or toxic nodular goitre (16%). Hyperthyroidism can also be caused by subacute granulomatous thyroiditis (3%) and drugs (9%) such as amiodarone, tyrosine kinase inhibitors, and immune checkpoint inhibitors. Disease-specific recommendations are given. Currently, Graves' hyperthyroidism is preferably treated with antithyroid drugs. However, recurrence of hyperthyroidism after a 12-18 month course of antithyroid drugs occurs in approximately 50% of patients. Being younger than 40 years, having FT4 concentrations that are 40 pmol/L or higher, having TSH-binding inhibitory immunoglobulins that are higher than 6 U/L, and having a goitre size that is equivalent to or larger than WHO grade 2 before the start of treatment with antithyroid drugs increase risk of recurrence. Long-term treatment with antithyroid drugs (ie, 5-10 years of treatment) is feasible and associated with fewer recurrences (15%) than short-term treatment (ie, 12-18 months of treatment). Toxic nodular goitre is mostly treated with radioiodine (131I) or thyroidectomy and is rarely treated with radiofrequency ablation. Destructive thyrotoxicosis is usually mild and transient, requiring steroids only in severe cases. Specific attention is given to patients with hyperthyroidism who are pregnant, have COVID-19, or have other complications (eg, atrial fibrillation, thyrotoxic periodic paralysis, and thyroid storm). Hyperthyroidism is associated with increased mortality. Prognosis might be improved by rapid and sustained control of hyperthyroidism. Innovative new treatments are expected for Graves' disease, by targeting B cells or TSH receptors.

Graves' disease: moving forwards.

Graves' disease is a rare disorder that continues to present clinicians and families with a series of challenges. There are no new established treatments for children or adolescents, but the outcomes of recent clinical trials and meta-analyses have helped clinicians to prepare families for the road ahead. We have a more refined understanding of how to administer antithyroid drugs, which one to use and how long to treat the young person. We also have a greater insight into how best to reduce any risks associated with surgery and radioiodine. We understand more about long-term outcomes and their determinants and have greater awareness about the impact of the disease and its treatment on quality of life. A holistic approach to management is key to supporting and counselling young people and their families about the diagnosis and management options. In this review, we will discuss the recent literature and reflect on how this should be translated into clinical practice.

Antigen-specific immunotherapy to restore antigen-specific tolerance in Type 1 diabetes and Graves' disease.

Type 1 diabetes and Graves' disease are chronic autoimmune conditions, characterized by a dysregulated immune response. In Type 1 diabetes, there is beta cell destruction and subsequent insulin deficiency whereas in Graves' disease, there is unregulated excessive thyroid hormone production. Both diseases result in significant psychosocial, physiological, and emotional burden. There are associated risks of diabetic ketoacidosis and hypoglycaemia in Type 1 diabetes and risks of thyrotoxicosis and orbitopathy in Graves' disease. Advances in the understanding of the immunopathogenesis and response to immunotherapy in Type 1 diabetes and Graves' disease have facilitated the introduction of targeted therapies to induce self-tolerance, and subsequently, the potential to induce long-term remission if effective. We explore current research surrounding the use of antigen-specific immunotherapies, with a focus on human studies, in Type 1 diabetes and Graves' disease including protein-based, peptide-based, dendritic-cell-based, and nanoparticle-based immunotherapies, including discussion of factors to be considered when translating immunotherapies to clinical practice.

2021 Asia-Pacific Graves' Disease Consortium Survey of Clinical Practice Patterns in the Management of Graves' Disease.

AIM: Although Graves' disease (GD) is common in endocrine practices worldwide, global differences in diagnosis and management remain. We sought to assess the current practices for GD in countries across Asia and the Pacific (APAC), and to compare these with previously published surveys from North America and Europe. METHODS: A web-based survey on GD management was conducted on practicing clinicians. Responses from 542 clinicians were received and subsequently analysed and compared to outcomes from similar surveys from other regions. RESULTS: A total of 542 respondents participated in the survey, 515 (95%) of whom completed all sections. Of these, 86% were medical specialists, 11% surgeons, and 3% nuclear medicine physicians. In addition to serum thyroid-stimulating hormone (TSH) and free thyroxine assays, most respondents would request TSH-receptor autoantibody (TRAb) measurement (68%) during initial work-up. Thyroid ultrasound is requested by about half of respondents (53%), while the use of nuclear medicine scans is limited. The preferred first-line treatment is anti-thyroid drug (ATD) therapy (79%) with methimazole (MMI) or carbimazole (CBZ), followed by radioiodine (RAI; 19%) and surgery (2%). In case of surgery, one-third of respondents would opt for a subtotal rather than a total thyroidectomy. In case of mild Graves orbitopathy (GO), ATDs (67%) remains the preferred treatment, but a larger proportion of clinicians prefer surgery (20%). For a patient with intention to conceive, the preferred treatment pattern remained unchanged, although propylthiouracil (PTU) became the preferred ATD-agent during the first trimester. In comparison to European and American practices, marked differences were noted in the relatively infrequent usage of nuclear medicine scans and the overall higher use of a ATDs and ß-blockers and adjunctive ATD-treatment during RAI in the APAC-group. CONCLUSION: Although regional differences regarding the diagnosis and management of GD are apparent in this first pan-Asia-Pacific survey, this study reveals the overall approach to the management of this disease in Asia-Pacific generally tends to fall between the trends appreciated in the American and European cohorts.

Graves' disease, myxedema, and papillary thyroid carcinoma / Doença de Graves, mixedema e carcinoma papilífero de tireoide

Graves' disease (GD) is the leading cause of hyperthyroidism and diffuse toxic goiter in iodine-sufficient geographi-cal areas. GD is associated with classical manifestations such as ophthalmopathy and thyroid dermopathy, in addi-tion to diffuse goiter, which may be the site of carcinomas, as a complication. Case report: A 52-year-old woman presented with goiter and symptoms compatible with hyperthyroidism, such as heat intolerance, weight loss, fati-gue, increased sweat, tachycardia, fine tremors, increased intestinal transit, anxiety, emotional lability, insomnia, exophthalmos, and pretibial myxedema. A complementary investigation confirmed the diagnosis of hyperthyroidism (high free T4 and total T3 levels and low thyroid-stimulating hormone - TSH levels). Ultrasound images showed dif-fuse enlargement of the thyroid lobes by approximately 10 times and the presence of three thyroid nodules, one of which was larger than 2 cm with heterogeneous echogenicity and vascularization throughout the nodule; ultrasoun-d-guided fine needle aspiration revealed cytology compatible with Bethesda IV; scintigraphy revealed a low uptake area (cold nodule) amid a diffuse high-uptake goiter. A thyroidectomy was performed, and the anatomical specimen diagnosis revealed papillary thyroid carcinoma in the right lobe, with adjacent parenchyma compatible with GD. Histopathological examination of the skin showed the presence of myxedema compatible with Graves' dermopathy. The patient evolved with the normalization of TSH levels and a reduction of cutaneous manifestations. Conclusion:GD abnormalities may not be restricted to the classic clinical manifestations, and a careful investigation may reveal the coexistence of carcinomas. (AU)

A doença de Graves (DG) é a principal causa de hipertireoidismo e bócio difuso tóxico em áreas geográficas com iodo suficiente. DG está associada a manifestações clínicas clássicas como oftalmopatia e dermopatia da tireoide, além do bócio difuso, que pode ser sítio de carcinomas, como uma complicação. Relato de caso: Mulher de 52 anos apresentou bócio e sintomas compatíveis com hipertireoidismo como intolerância ao calor, emagrecimento, fadiga, sudorese aumentada, taquicardia, tremores finos, trânsito intestinal aumentado, ansiedade, labilidade emocional, insônia, exoftalmia e mixedema pré-tibial. A investigação complementar confirmou o diagnóstico de hipertireoidis-mo (níveis elevados de T4 livre e T3 total; níveis baixos de hormônio estimulante da tireoide - TSH). As imagens ultrassonográficas mostraram aumento difuso dos lobos tireoidianos em aproximadamente 10 vezes e a presença de três nódulos tireoidianos, um dos quais, maior que 2 cm, com ecogenicidade e vascularização heterogêneas em todo o nódulo, cuja punção aspirativa por agulha fina guiada por ultrassom revelou citologia compatível com Bethesda IV; e a cintilografia evidenciou uma área de baixa captação (nódulo frio) em meio a um bócio difuso de alta captação. Foi realizada tireoidectomia e o diagnóstico da peça anatômica revelou carcinoma papilífero de tir-eoide em lobo direito, com parênquima adjacente compatível com DG. O exame histopatológico da pele mostrou a presença de mixedema compatível com dermopatia de Graves. A paciente evoluiu com normalização dos níveis de TSH e redução das manifestações cutâneas. Conclusão: As anormalidades da DG podem não estar restritas às manifestações clínicas clássicas, e uma investigação criteriosa pode revelar a coexistência de carcinomas, (AU)

Evolution of Graves' Disease during Immune Reconstitution following Nonmyeloablative Haploidentical Peripheral Blood Stem Cell Transplantation in a Boy Carrying Germline SAMD9L and FLT3 Variants.

Graves' disease, characterized by hyperthyroidism resulting from loss of immune tolerance to thyroid autoantigens, may be attributable to both genetic and environmental factors. Allogeneic hematopoietic stem cell transplantation (HSCT) represents a means to induce immunotolerance via an artificial immune environment. We present a male patient with severe aplastic anemia arising from a germline SAMD9L missense mutation who successfully underwent HSCT from his HLA-haploidentical SAMD9L non-mutated father together with nonmyeloablative conditioning and post-transplant cyclophosphamide at 8 years of age. He did not suffer graft-versus-host disease, but Graves' disease evolved 10 months post-transplant when cyclosporine was discontinued for one month. Reconstitution of peripheral lymphocyte subsets was found to be transiently downregulated shortly after Graves' disease onset but recovered upon antithyroid treatment. Our investigation revealed the presence of genetic factors associated with Graves' disease, including HLA-B*46:01 and HLA-DRB1*09:01 haplotypes carried by the asymptomatic donor and germline FLT3 c.2500C>T mutation carried by both the patient and the donor. Given his current euthyroid state with normal hematopoiesis, the patient has returned to normal school life. This rare event of Graves' disease in a young boy arising from special HSCT circumstances indicates that both the genetic background and the HSCT environment can prompt the evolution of Graves' disease.

Four cases of Graves' disease following viral vector severe acute respiratory syndrome corona virus-2 (SARS-CoV-2) vaccine.

Mass immunization has led to a decrease in the transmission of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) worldwide. At the same time, awareness regarding possible adverse effects of newly developed vaccines is critical. The present study was undertaken to report the cases of Graves' disease occurring after administration of viral vector vaccine (ChAdox1nCoV-19) and describe the clinical profile, response to treatment, and effect of administration of a second dose in patients developing Graves' disease. Four cases of Graves' disease after administration of the vaccine were noted. Two of these had a mild thyroid eye disease. Three cases were female and had a family/self-history of autoimmune disease. All cases responded well to treatment and became euthyroid within two to four months. Two patients exhibited worsening thyrotoxicosis after receiving a second dose of the vaccine. We propose that the temporal relationship between administration of the vaccine and the onset of symptoms establishes Graves' disease as an adverse event after the SARS-CoV-2 viral vector vaccine. Close follow-up is advisable in individuals developing Graves' disease after SARS-CoV-2 vaccination.

Update on Pediatric Hyperthyroidism.

Typical symptoms which should lead to suspicion of hyperthyroidism are unintentional weight loss, tachycardia, and palpitations, heat intolerance, and hyperactivity. It is diagnosed by suppressed thyroid-stimulating hormone (TSH) with elevated thyroid hormone (TH) levels. Graves' disease (GD) due to antibodies stimulating the TSH receptor is the leading cause, and first-line treatment is with methimazole (MMI). Emerging data suggest MMI treatment, up to 8 years is effective and safe in improving the rate of remission. Radioactive iodine (RAI) and thyroidectomy offer definitive treatment and induce permanent hypothyroidism. Thyroid storm is a life-threatening condition with systemic decompensation and hyperpyrexia. Neonates of mothers with current or past GD are at risk for neonatal hyperthyroidism (NH). Appropriate identification and follow-up of at-risk neonates will reduce complications.

2022 Update on Clinical Management of Graves Disease and Thyroid Eye Disease.

The management of hyperthyroidism and extrathyroidal manifestations of Graves disease remains complex. Considerations that include patient preference, age, comorbidity, pregnancy, tobacco smoking, and social determinants of health must all be weaved into a cohesive management plan. A multidisciplinary team is required to manage all aspects of Graves disease, particularly thyroid eye disease, for which new therapeutic options are now available.

[Thyroiditis]. / Les thyroïdites.

A thyroiditis is an inflammatory disease of the thyroid whether autoimmune, infectious or drug-induced. Autoimmune thyroid diseases (including Hashimoto's thyroiditis and Graves' disease) are the most frequent of all autoimmune pathologies. The clinical presentation and history are often revealing of the pathology and its etiology. Complementary examinations allow to confirm the diagnosis and to follow the evolution of the disease. Sometimes the disease could have a mixed presentation associating two different causes (like a mixed autoimmunity for Graves and Hashimoto diseases). In these cases, the treatment options are not always straightforward and may need to be adapted with the clinical evolution.

: Les thyroïdites désignent, au sens large, toutes les pathologies inflammatoires de la thyroïde, qu'elles soient auto-immunes, infectieuses ou médicamenteuses. Dans les maladies auto-immunes, les thyroïdites auto-immunes, dont la maladie de Hashimoto et la maladie de Basedow, sont les plus communes. Le tableau clinique et l'anamnèse sont parfois très révélateurs de la pathologie et de son étiologie. Les examens complémentaires permettent de confirmer l'hypothèse diagnostique et de suivre l'évolution de la maladie. Parfois, le tableau est moins typique avec des formes mixtes associant deux entités (comme une maladie de Basedow et de Hashimoto). Le diagnostic est, dans ces cas, moins évident et la prise en charge thérapeutique peut nécessiter une adaptation dans le temps.
