Participants in this study will be patients diagnosed with or suspected to have a thyroid function disorder. These conditions may include: hypothyroidism, hyperthyroidism, thyroid hormone resistance, Graves' Dermopathy, and thyroid-stimulating hormone (TSH) secreting pituitary adenomas. The main purpose of this study is to further understand the natural history, clinical presentation, and genetics of thyroid function disorders. Many of the tests performed are in the context of standard medical care that is offered to all patients with thyroid function disorders. In addition, blood and tissue samples may be taken for research and genetic studies.

NCT04856488
The purpose of this study is to assess if preoperative treatment with Lugol's solution prior to thyroidectomy can reduce the surgical complications hypoparathyroidism and laryngeal nerve palsy
NCT05774535
The evaluation of carotid intima-media thickness (cIMT) has become a possible predictor of the future risk of cardiovascular diseases (CVD). Evidence to date shows that cIMT augmentation is correlated with the extent of atherosclerosis in the coronary arteries and with other risk factors for CVD. More recently, several studies have evaluated the association of cIMT with stroke, to determine whether this measure can also predict future cardiovascular events. Although the published evidence is scarce and fragmentary, the cIMT retains an increasingly interesting role as a marker of atherosclerotic pathology. The purpose of the study is to analyze cIMT in patients undergoing thyroidectomy to evaluate a possible correlation between the cIMT variation after the procedure and the cause of the thyroid disease, the levels of thyroid hormones, and the lipid or other markers of atherosclerosis levels. The primary endpoint will be the variation of the measure of the cIMT before and after surgery. Secondary endpoints will be: * major cardiovascular adverse events (death, major stroke, minor stroke, transient ischemic attack) in the short-term period (≤30 days after the procedure); * major cardiovascular adverse events (death, major stroke, minor stroke, transient ischemic attack) in the long-term period (\>30 days after the procedure); * the technical success of the procedure; * the rate of postoperative complications. To date, there are no data that differentiate patients based on the causes of thyroid disease. The results of the present study will allow for correlating the variation of the cIMT to the causes of thyroid disease, the levels of thyroid hormones, and the levels of lipid and other markers of atherosclerosis. Results from the present study may provide insights into possible areas of quality improvement. It may also influence the economic impact associated with carotid revascularization techniques, in terms of hospital charges and discharges to skilled nursing and rehabilitation facilities.

"Early paediatric Basedow disease is one of the rare endocrine diseases for which the Reference Centre for Rare Endocrine Growth Diseases, was approved by the Ministry of Health in 2005. In addition, the study will benefit from the expertise of public Health France (SFP). This study is therefore part of the missions of these partners (reference centre for endocrine growth diseases and Public Health France). For several years, our group has been interested in defining the evolutionary profile of these patients. A national study on short- and long-term patient follow-up has already been conducted, which has been the subject of two international publications29,30, as well as a study on a specific clinical form of the disease 24. This work was made possible thanks to the collaboration of paediatric clinical centres within the Reference Centre and Competence Centre for Rare Endocrine Diseases Network. The present study planned in France will make it possible to accurately characterize the care pathway and the frequency of complications associated with it at the national level.
NCT05385029
The thyroid gland has been shown to be a common target for COVID 19 virus. Babies born to mothers positive for COVID 19 infections were noticed to have elevated thyroid stimulating hormone ( TSH ) levels on screening. Thyroid function tests were monitored in these babies to determine presence of temporary or permanent thyroid disorders following COVID 19 infections during pregnancy.
NCT03823859
The aim of this study is to develop a metabolome signature of thyroid hormone status. The metabolome signature could be useful in diagnosis and treatment of thyroid dysfunction diseases, especially in cases where TSH cannot be reliably used.
NCT01945229
Background: Atrial fibrillation is a common heart rhythm disturbance affecting some 1-2% of the western population. It may cause symptoms such as irregular heartbeats, shortness of breath, and fatigue. It may also be asymptomatic (ie "silent atrial fibrillation). In some cases, atrial fibrillation is permanent whereas in others it is sporadic. Regardless of symptoms, there is an increased risk of stroke in some patients with this condition. Novel technologies are being developed to increase detection of silent atrial fibrillation, in order to find patients who might benefit from treatment with oral anticoagulants (blood-thinning medications) in order to reduce the risk of stroke. One of these technologies is thumb-ECG, a simple way for a patient to have his or her heart rhythm reliably analyzed at home. Hyperthyroidism (sometimes referred to as "toxic goiter") is defined as an excessive production of thyroid hormone. It is known that hyperthyroidism may cause atrial fibrillation in about 8% of cases. Objective: To provide thumb-ECG-monitors to hyperthyroid patients before and after treating their hormonal disturbance, in order to find episodes of silent atrial fibrillation. Design: Prospective observational study. Hypotheses: * Primary hypothesis: Silent atrial fibrillation is at least as common as overt atrial fibrillation in hyperthyroid patients. * Secondary hypothesis nr 1: Atrial fibrillation continues to be more prevalent compared to the normal population even after hyperthyroidism is treated. * Secondary hypothesis nr 2: The majority of patients with hyperthyroidism and atrial fibrillation are at increased risk of stroke and should be considered for treatment with oral anticoagulants.

NCT04304794
The proper synthesis of thyroid hormones is dependent on adequate iodine supply. The mean daily iodine intake recommended by World Health Organization is 150 mg. Iodinated contrast medium (ICM) typically contains 13 500 mg of free iodine and 15-60 g of bound iodine, an amount well above acceptable upper level. In a situation of excess iodine, thyroid discontinues the release of hormones (Wolff-Chaikoff effect), which is usually transient, although can persist causing hypothyroidism. Iodine-induced hyperthyroidism (IIH), known as the Jod-Basedow phenomenon is infrequent, but elderly patients and individuals with autonomously functioning nodular goiters are at higher risk of developing this dysfunction. According to recent studies the risk of ICM-induced hyperthyroidism appears to be low. The prevalence has not been well assessed and varies from 1 % to 10 %. Currently, there are no specific guidelines concerning the prophylactic therapy of IIH. American Thyroid Association (ATA) does not recommend routine administration of antithyroid drugs before iodinated contrast medium for all patients, however, advises to consider prophylaxis in patients at high risk of developing IIH or with cardiovascular comorbidities. ATA recommends avoidance of additional iodine and administration of b-blockers alone or with antithyroid drugs as a treatment of IIH, depending on the severity of hyperthyroidism. This study was performed to evaluate the influence of ICM on thyroid status and advantages of prophylactic therapy during ICM exposure in patients with euthyroid goiter and cardiovascular comorbidities. The association between the incidence of IIH and thyroid volume was also assessed.
NCT03379181
The overall objective of the HEAT study is to determine the acute effect of propranolol on energy expenditure in patients suffering from hyperthyroidism and to evaluate the consequences of the change of hyper- to euthyroidism on metabolism during the course of treatment, especially with regard to the reaction to cold ambient temperatures.
NCT03303053
Hyperthyroidism is the second most common endocrine disorder in the world with Graves' disease being the commonest. Anti thyroid drugs including methimazole, carbimazole, and propylthiouracil are effective treatments but take in most cases between 6 to 8 weeks to achieve euthyroidism. This study aim to assess the efficacy of cholestyramine and prednisolone as adjunctive treatment to standard treatment in patients with overt hyperthyroidism in 4 weeks.
NCT00946296
The purpose of this study is to determine whether a brief course of SSKI (saturated solution of potassium iodide) administered preoperatively provides any benefit in the surgical management of patients undergoing thyroidectomy as definitive management of their Graves Disease.
NCT00822289
Because of the high iodine uptake in the stomach, radioactive iodine treatment for thyroid diseases (cancer or hyperthyroidism) or radioactive iodine administered for thyroid scan may be able to eradicate H.pylori infection from the stomach of patients infected with H.pylori. Also to test the hypothesis that CagA virulent strains of H.pylori are more common in patients with thyroid cancer than with other thyroid diseases.
