Active clinical trials for "Thyroid Diseases"

Patients admitted to the hospital with acute illness may have a wide spectrum of thyroid function abnormalities. It is largely unknown whether such aberrations are temporary or persist for a long time, and whether they impact prognosis of such patients.

To compare the effects and safety of Anlotinib with placebo in patients with Medullary Thyroid Carcinoma.

Papillary thyroid cancer (PTC) is the most common subtype of thyroid cancer. The most common site of PTC nodal metastases is the central neck, which has a reported rate of lymph node metastases as high as 50%~70%. Central neck dissection has important value to ensure accurate clinical staging and surgical planning. As a novel lymphatic tracer, carbon nanoparticles (CN) have been applied successfully in the detection of sentinel lymph nodes in breast and gastric cancers, while not been used as a lymphatic tracer for PTC. The goal of this study was to evaluate whether the use of CN facilitates the detection of lymph nodes, increases the number of metastatic lymph nodes removed, accurately reflects the metastatic condition of the central neck, and has the potential to protect the parathyroid glands.

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.

The overall objective is to investigate the efficacy, tolerability, and safety of teprotumumab (a fully human monoclonal antibody [mAb] inhibitor of the insulin-like growth factor-1 receptor [IGF-1R]) administered once every 3 weeks (q3W) for 21 weeks with a final assessment at Week 24, in comparison to placebo, in the treatment of participants with moderate-to-severe active thyroid eye disease (TED).

Background: Medullary thyroid cancer (MTC) is a tumor of the thyroid gland. Surgery is the only current treatment to cure it. The drug pembrolizumab (MK-3475) is a new type of cancer therapy. It works by allowing the immune system to detect and kill tumor cells. Objective: To test how pembrolizumab affects people with MTC and if it can offer them clinical benefit. Eligibility: People ages 18 and older with MTC Patients who have recurrent or metastatic MTC, for whom surgery is not a curative option Patients with some imaging evidence of MTC Patients with minimal symptoms related to MTC Design: Participants will be screened with: Medical history Physical exam Blood, urine, and heart tests Computed tomography (CT) scan or magnetic resonance imaging (MRI): They lie in a machine that takes pictures of the body. Bone scan Participants will be put in a group based on their treatment history: Group 1 if they have had an immune stimulating cancer vaccine Group 2 if they have had no vaccine Participants will receive the study drug as a 30-minute intravenous (IV) infusion every 3 weeks. Treatment will continue for up to 2 years as long as they tolerate it and their disease does not get worse. Participants will have physical exams and blood tests on the day of each infusion. They will have CT and bone scans every 3 months. Participants may save biopsies before treatment and after starting treatment. Participants will have a final visit 3-4 weeks after stopping treatment. This will include a physical exam and blood and heart tests. After this study, participants can join a long-term follow-up study.

The purpose of this study is to evaluate thyroid nodule's volume, structure and vascularisation changes following HIFU therapy assessed by ultrasonography

Phase I/II Clinical Trial of Dose-tolerance, Pharmacokinetics and Iodine Uptake Effects For Recombinant Human Thyroid Stimulating Hormone In Post-thyroidectomized Patients

Blood will be drawn 1 month before and 2 month after regular radioactive iodine treatment. Monocytes will be isolated. The three main outcomes are whole blood counts, cytokine production upon in vitro stimulation of monocytes and in vitro ROS production by monocytes. These results are compared between patients treated in adjuvant setting and patients treated for persistent structural disease, and between pre- and post-treatment status.

There is no scientific data on post-thermal ablation cytological aspects, but treated nodules that grow back significantly after a procedure justify a new cytology in order not to ignore a neoplastic process. The EU-TIRADS classification usually used to stratify the risk of cancer (and to justify a fine needle aspiration biopsy) of thyroid nodules is not validated for nodules treated by thermal ablation (TA) (post-RF nodules). However, these nodules often acquire ultrasound criteria of suspicion making it necessary to develop an ultrasound stratification of the risk of malignancy specific to nodules treated by TA. The objective of this work is to describe the ultrasound and cytological aspects of these treated nodules by performing a systematic assessment at 3 years after thermal ablation including systematic neck ultrasound and fine needle aspiration biopsy. Thus, an ultrasound and cytological atlas (Bethesda classification 2017) of nodules treated by thermal ablation will be constituted.
