NCT ID: NCT01428167 Completed - Thyroid Cancer Clinical Trials

Hashimotos Thyroiditis and Thyroid Cancer

Thyroid Cancer
Start date: June 2011
Phase: N/A
Study type: Observational

Thyroid cancer (TC) is the most common endocrine malignancy. The association between inflammation and cancer is well established but the association between thyroiditis (inflammation of thyroid gland) especially Hashimoto's thyroiditis (HT) and thyroid cancer remains controversial. Chronic inflammation leads to a repeated cycle of cellular damage and subsequent healing which contributes to inappropriate cell proliferation and subsequent neoplastic transformation. One of the most common forms of Thyroiditis is Hashimoto's thyroiditis which is a chronic autoimmune inflammatory disease affects almost 5% of the population and is more common in women. For the first time, Dailey and Lindsay reported in 1955 an increased association between Hashimoto's Thyroiditis (HT) and thyroid cancer. They reported 35 thyroid cancers in 278 patients with Hashimoto's Thyroiditis, a prevalence of 17.7% which they considered higher than the general population . Since then, various studies have been done, some studies have reported an increased risk of malignancy in Hashimoto's thyroiditis; others have failed to find an association. Most of the studies that have been done to identify the association between Hashimoto's thyroiditis and thyroid cancer are retrospective. The purpose of this pilot case-control study is to identify the association of Hashimoto's thyroiditis and thyroid cancer, to determine if the presence of Hashimoto's thyroiditis has any affect on the complication of thyroidectomy and prognostic factors of thyroid cancer.

NCT ID: NCT01270425 Completed - Systemic Sclerosis Clinical Trials

Sonographic and Laboratory Evaluation of the Thyroid Gland in Patients With Systemic Sclerosis

Start date: January 2011
Phase: N/A
Study type: Observational

Systemic sclerosis (SSc) is a systemic disease that involves various organs such as the skin, kidneys, gastrointestinal tract and lungs. Dysfunction of the thyroid gland is prevalent in these patients and may be related to thyroid fibrosis or to thyroid autoimmune disease, i.e. hashimoto's thyroiditis. Thyroid nodules are prevalent in the general population, although some reports suggest they might be more frequent in patients with SSc. Hashimoto's thyroiditis, by itself, carries a higher risk for thyroid nodules and thyroid cancer. The aim of the study:To characterize sonographycally the thyroid gland of patients with SSc with and without Hashimoto's disease

NCT ID: NCT01227499 Completed - Graves Disease Clinical Trials

Differential Diagnosis of STA-PSV in Thyrotoxicosis

Start date: June 2010
Phase: N/A
Study type: Observational

Aim: Graves's disease and thyroiditis can both characterized with thyrotoxicosis, but their clinical outcome and therapy is quiet different. Measurement of iodine uptake is the gold standard to differential diagnosis the thyroiditis or Graves's disease. But the iodine uptake is limited for its availability in china and easily influenced by medicine or food contained iodine.The blood pattern of thyroid CFDS is useful for differentiate the cause of thyrotoxicosis.Most previous studies using the descriptive pattern of thyroid CFDS is easily varied by operator subjective judgement. This study is focus on the role of peak systolic velocity of thyroid superior artery in differential diagnosis of thyrotoxicosis. Methods: Patients with thyrotoxicosis symptoms without recent medicine history were enrolled in two clinical center. Its thyroid function, iodine uptake , CFDS of thyroid and peak systolic velocity of thyroid superior artery is detected. Thyrotoxicosis is defined as TSH level below the low value of normal range. Graves disease is defined as the typical symptoms of graves disease such as graves ophthalmopathy or increased iodine uptake. Thyroiditis is defined as lack of typical symptoms of graves disease or decreased iodine uptake.We use receiver operator curve(ROC) to evaluate its diagnosis value

NCT ID: NCT01129492 Completed - Clinical trials for Autoimmune Thyroiditis

Low-Level Laser Therapy in Chronic Autoimmune Thyroiditis

Start date: March 2006
Phase: Phase 2
Study type: Interventional

The purpose of this study is to evaluate whether low-level Laser therapy is effective in ameliorating the thyroid function of patients with hypothyroidism caused by chronic autoimmune thyroiditis.

NCT ID: NCT00552487 Completed - Clinical trials for Adrenal Insufficiency

Isolated ACTH Deficiency in Patients With Hashimoto Thyroiditis

Start date: October 2005
Phase: N/A
Study type: Interventional

The purpose of this study is to determine whether patients with Hashimoto thyroiditis and impaired well-being may have a partial secondary adrenocortical insufficiency.

NCT ID: NCT00271427 Completed - Clinical trials for Autoimmune Thyroiditis

Selenium Treatment in Autoimmune Thyroiditis (AIT)

Start date: December 2004
Phase: N/A
Study type: Interventional

Selenium suppresses autoimmune destruction of thyrocytes and decreases titers of serum TPOAb in AIT patients. Older 4 clinical trials approved the efficacy of the daily dose of 200micg. It's believed that Se saturates the deficient stores of GPX so GPX saves the thyrocytes against to oxidative stresses. Although less than 70 micg/d is sufficient to maximize GPX activity, none of the authors tested the doses less than 200 micg/d. Our hypothesis was that If 100 micg/d can not suppress the TPOAb titers,it means autoimmune destruction can not be blocked by saturation of deficient stores of GPX solely and the mechanism of action requires more than repletion of deficient stores. It's important not only to estimate the optimal dose but to understand the mechanism of action. High dose therapy may also suppress TPOAb levels in Se-non-deficient AIT patients, if it is so, Se therapy may becomes the solely treatment modality which can suppress the autoimmunity in more than 400 million AIT patients. Because there've been no way to suppress autoimmune war and replacement of LT4 had been the only treatment modality for palliation. An other independent part of the study is to test the effect of Se in adolescent AIT patients.
