Filter by: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.
Retrospective comparative study comparing group 1 (TSH level 0.1-1.99 mIU/L) and group 2 (TSH level 2.0-4 mIU/L). Each group was further subdivided into primigravidae and multipara. 1527 pregnant women were included.
This is an observational, retrospective and monocentric study, conducted at the university Hospital of Brest The primary objective is to assess the association between the occurrence of thyroid dysfunction in patients treated with Nivolumab® for a non-small cell lung cancer and prognosis and therapeutic response The second objective is to assess prognosis and therapeutic response according to severity and subtype of thyroid dysfunction
The aim of the study: To assess the influence of iontophoresis treatment with 2% potassium iodide on the level of thyroid hormones (TSH, FT3, FT4) The study group: conducting 10 iontophoresis treatments with Potassium iodide; The control group: conducting 10 placebo treatments with iontophoresis with destilled water; Intervention: 10 iontophoresis treatments with 2% potassium iodide in healthy individuals. Test the level of thyroid hormones before and after the 10 iontophoresis treatments; The study allows to assess the influence of iodine on the function of thuroid gland.
Coronary heart disease (CHD) and heart failure (HF) are the leading causes of mortality and morbidity, particularly with the current context of an aging population. Prospective cohort studies, as well as analyses of pooled individual participant data suggest up to a 60-90% increase in the risk of CHD or HF events among adults with severe SHypo. However, no large randomized controlled trials (RCT) have assessed the impact of thyroid replacement on cardiovascular (CV) imaging outcomes. The goals of this proposal are to address the impact of thyroid replacement on cardiac function. The investigators will conduct a RCT in 185 patients with subclinical hypothyroidism who will be randomly assigned to thyroxine or placebo with an average follow-up of 24 months from baseline. The main outcome will be CV imaging modalities measured by echocardiography at the close-out visit. Assessment of the impact of thyroid replacement on cardiac function and subclinical atherosclerosis within a trial will aid decisions and evidence-based guidelines development to treat a potential modifiable risk factor, such as SHypo.

The investigators will conduct a RCT in 185 patients with subclinical hypothyroidism who will be randomly assigned to thyroxine or placebo with an average follow-up of 24 months from baseline. The main outcome will be CV imaging modalities measured by carotid ultrasound at the close-out visit. Assessment of the impact of thyroid replacement on subclinical atherosclerosis within a trial will aid decisions and evidence-based guidelines development to treat a potential modifiable risk factor, such as SHypo.
Thyroid hormone is a key regulatory hormone for a range of physiological systems. An impaired function of the thyroid gland such as subclinical hypothyroidism (SCH) can affect quality of life. Older adults with subclinical hypothyroidism often report non-specific symptoms such as tiredness. In addition, muscle symptoms such as cramps, weakness and myalgia are more common in SCH than in healthy controls. At present, evidence is lacking about the benefits of thyroxine replacement in the elderly with SCH, as no large randomized clinical trials (RCT) on the full range of relevant clinical outcomes, including tiredness have been performed. Moreover, there is continued uncertainty about the long-term impact on health related quality of life of thyroxine treatment for SCH. The aim of the study is to examine, within a large RCT of elderly participants with subclinical hypothyroidism, the impact of thyroxine therapy on the association between subclinical thyroid disease (SCTD) and the level of physical and mental fatigue. The existing trial infrastructure (TRUST thyroid trial-Euresearch FP7; clinicaltrials.gov ID: NCT 01660126) will be utilized to collect information on the level of physical and mental fatigue by using the Pittsburgh Fatigability Scale at baseline and at 1 year from 220 participants with persistent subclinical hypothyroidism randomized to either thyroxine or placebo.
Thyroid hormone is a key regulatory hormone for a range of physiological systems, including the skeleton. Previous studies have suggested that subclinical thyroid dysfunction (SCTD) may be associated with deleterious skeletal effects. However, controversy persists on the clinical relevance of SCTD as well as on optimal thresholds for treatment. Available data have substantial limitations: 1) limited prospective data are available to assess the associations between SCTD and non-cardiovascular outcomes, such as fractures 2) lack of data from large RCTs to investigate the pathophysiological mechanisms of associations between thyroid hormone and bone loss. The aim of the study is to examine the relationship between subclinical hypothyroidism and thyroid hormone replacement in regard to skeletal fragility, bone mineral density (BMD), bone loss and metabolism, and the risk of fractures in elderly participants. The listed parameters will be assessed by dual energy X ray absorptiometry (DXA) and novel bone imaging techniques at baseline, at 1 year of follow-up. The study will be nested in the TRUST trial (clinicaltrials.gov ID: NCT01660126), and will make use of its study infrastructure to determine bone biomarkers from biospecimens at baseline, and at 1 year of follow-up from 145 Swiss participants with persistent subclinical hypothyroidism randomized to either thyroxine or placebo in Bern and Lausanne.
Specific Aim I: Determine absorption of iodine after oropharyngeal application of povidone-iodine 10% solution when used in head and neck surgery involving the upper aero-digestive tract. Specific Aim II: Measurement of iodine induced changes in thyroid function.
Overt hyperthyroidism and hypothyroidism are associated with inverted hemodynamic changes.Regional blood flow disturbances (including intrathyroidal) were also reported in these thyroid disorders. The purpose of this study is to investigate the thyroid vascularity and blood flow by Color Flow Doppler Sonography in patients with subclinical thyroid dysfunction
