Filter by:The aim of the study is to measure urinary milk iodine concentration (MIC), iodine concentration (UIC), thyroid hormones (TSH, FT4) and thyroperoxidase antibodies (TPOab) in breast-feeding women, and UIC in their nursing infants to determine if the levels are adequate, and to see how they can be influenced by 150 ug daily iodine supplementation in breast-feeding women. The hypothesis is that there is a relative iodine deficiency in this sub-population - lactating women and nursing children-, and that this can be influenced by iodine supplementation. Adequate thyroid hormone and iodine levels are very important for small children, when the plasticity of the brain is greatest. This is as a prospective, double-blind, placebo-controlled study of 221 mothers and their infants. In parallel, 90 age-matched healthy non-pregnant women are recruited. Mothers are randomized to 150 µg/day iodide supplementation or placebo. Pregnant women are asked for participation on a visit in pregnancy week 37, at the mother health care (MVC) at Mölnlycke and Skövde. The study will run for approximately 3 months for each individual and begins by sampling A (UIC, TSH, FT4, TPOab) at week 37 of the pregnancy, when mothers also get randomized to 150 µg iodine or placebo. New sampling B (UIC, TSH, FT4, MIC ) is collected when the baby is 3 months old. Thereafter the study is completed. In parallel, 90 healthy non-pregnant, non-lactating women in the same age range are recruited and followed with UIC, TSH, FT4, TPOab for 6 months as a control group. In each case a simple questionnaire is filled and blood is also frozen for future analyses.
The Personalized Discovery Process is the only program offering patients treatment recommendations based on an empirically constructed Drosophila "fly" model of their disease. Special committee selects one of the one of the few 2-3 FDA approved drug combinations or single agents that improved survival in the fly cancer model.
Thyroid eye disease (TED) is an autoimmune inflammation of the orbital tissues that develops in up to 50% of patients with Graves' disease. Although about 80% respond to IVGC initially, the relapse rate is high and about 75% require further surgery despite initial response. Although the natural history of TED is associated with spontaneous remissions after about 1 to 3 years, many irreversible serious ophthalmic and orbital complications can arise during this time. Therefore, there is a need for improved intervention strategies in the early active inflammatory phase of TED, to avoid progression to the cicatricial stage where disease manifestations can only be addressed in a rehabilitative fashion. The primary immunopathogenesis of Graves' disease is considered to be activation of B cells that then produce autoantibody against thyrotropin receptors in the thyroid (TRAb). Like in many autoimmune diseases, the inflammatory CD4+ T cell subset known as Th17 cells is also increased in blood of patients with active Graves' disease; the putative Th17 cytokine, IL-17, is also increased in serum and tears of TED patients. There is also an emerging pathogenic role for Th17 cells that co-express the chemokine receptor CXCR5 and drive autoantibody production. The contribution of Th17 cells to TED is not well defined. This study is an observational, longitudinal, prospective study of patients receiving treatment for thyroid eye disease.
The purpose of this study is to assess the efficacy and safety of High Intensity Focalized Ultrasound (HIFU) in the treatment for toxic Thyroids nodules
We assess the effectiveness of percutaneous ethanol ablation for the treatment of thyroid cancer.
Diindolylmethane (DIM), a dietary supplement, found naturally in cruciferous vegetables (such as cabbage, cauliflower, broccoli, & Brussels sprouts) has been studied extensively in recent years for its anti-cancer effects. DIM has been shown to exert control over cancer cell growth in breast, uterine, cervical, ovarian, and colon cancer. To date no human study has been published regarding the bioavailability of DIM in thyroid tissue or its effects in proliferative thyroid disease. Our previous study attempted to elucidate DIM's promotion of anti-proliferative estrogen metabolites in proliferative thyroid disease and ascertain its uptake in thyroid tissue. DIM has been shown to concentrate in the thyroid gland. Furthermore, thyroid volumes have been seen to decrease subjectively. This study would continue our attempt to elucidate DIM's promotion of anti-proliferative estrogen metabolites in proliferative thyroid disease.
The study is designed to evaluate the clinical efficacy, safety and tolerability of selumetinib with radioactive iodine therapy in patients with differentiated thyroid cancer.
Background: - Medullary thyroid cancer (MTC) represents 5% of thyroid cancers and presents as a hereditary (25% of cases) or sporadic (75% of cases) neuroendocrine malignancy. - MTC arises from the parafollicular C-cells of the thyroid. - Germline mutations in the rearranged during transfection (RET) proto-oncogene occur in virtually all of hereditary MTC cases, and somatic RET mutations occur in 50% of sporadic cases. - Drugs targeting RET kinase such as vandetanib and cabozantinib have shown efficacy in the treatment of advanced or metastatic MTC, however, more effective RET inhibitors are needed for previously untreated patients as well as patients who have become refractory to other molecular targeted therapeutics (MTTs). - Ponatinib, a drug that is Food and Drug Administration (FDA) approved as a therapy for chronic myelogenous leukemia (CML) and Philadelphia chromosome-positive acute lymphoblastic leukemia (Ph+ ALL), is a potent inhibitor of RET kinase. Primary Objective: -To determine the objective overall response rate (complete response [CR] + partial response [PR] by Response Evaluation Criteria in Solid Tumors (RECIST) to ponatinib in the treatment of patients with advanced or metastatic MTC previously treated with cabozantinib and vandetanib who: 1) have tumors with RET mutations and 2) have tumors without RET mutations. Eligibility: - Patients must have histologically confirmed, unresectable, locally advanced or metastatic MTC, with measurable disease by RECIST criteria. - Patients must have disease amenable to biopsy and be willing to undergo biopsy for molecular analysis, and also have adequate archival material from their thyroidectomy or from a tumor biopsy obtained prior to beginning any systemic therapy. - Patients must have failed or been intolerant to prior treatment with both cabozantinib and vandetanib. - The last dose of prior systemic therapy must be more than 28 days prior to the first dose of ponatinib - Radiation therapy is permitted if the last treatment was received more than 28 days prior to the first dose of ponatinib. Design: - Open label phase II trial with 2 treatment groups: - RET mutation positive MTC, previously treated with vandetanib and cabozantinib - RET mutation negative MTC, previously treated with vandetanib and cabozantinib - Patients will receive ponatinib 30 mg orally daily until disease progression or until the development of intolerable side effects. - Tumor response will be assessed by RECIST 1.1 criteria at 8 weeks and then every 12 weeks thereafter. After one year on study, tumor response will be assessed every 16 weeks. - Patients will have a biopsy of their MTC for molecular analysis prior to initiating treatment with ponatinib. Patients will also have a biopsy of their MTC at the time of tumor progression, should that occur.
Thyroid eye disease (TED) is an autoimmune disease that affects the eye area. The disease presents with a variety of physical findings, including bulging of the eyes (proptosis), upper and lower eyelid retraction, and swelling/inflammation of the eye itself. The disease passes through two phases: active and inactive. The active phase lasts between 18 and 24 months. During this phase, TED signs and symptoms generally worsen and then often improve. The inactive phase follows, during which the signs and symptoms of TED cease to improve and usually stabilize. Lid retraction is a cardinal sign of TED. In addition to potentially causing cornea damage due to improper lid closure, lid retraction is also very troublesome for patients due to its cosmetic appearance. The precise pathophysiology of lid retraction is poorly understood, but a leading hypothesis is that it occurs due to scarring and fibrosis in the muscles that lift the eyelid. Currently, the definitive treatment for lid retraction is surgery, which can be used to lengthen the lid itself or remove inflamed tissue from behind the eye, thus causing the eye to bulge less. In cases when patients first present to their physician with corneal ulceration or compression of the optic nerve, surgery may be performed immediately. However, in most instances, surgical procedures are delayed until the active stage of the disease has passed. Thus, most patients must endure the cosmetic and irritant symptoms of TED for up to two years. Hyaluronic Acid Gels (HAG) have been FDA approved for the treatment of facial rhytids (wrinkles). They are injected under the skin and work by increasing volume. Recently, some smaller retrospective research studies have shown that HAG is also effective in correcting upper and lower eyelid retraction in TED. Hence, HAG may be for patients with active stage TED. It is also thought that if employed early in active phase disease, HAG may also help to decrease the severity of associated symptoms and reduce the need for surgery. The purpose of the current investigation is to define the clinical utility of HAG correction of upper eyelid in active TED in terms of anatomic (lid position), quantitative (corneal dry eye signs) and qualitative effects (symptom severity and thyroid related quality of life).
Metastases of thyroid cancer with iodine uptake are treated with repeated activity of I-131 administered after thyroid hormone withdrawal. The goal of thyroid hormone withdrawal is to treat patients with elevated thyrotropin stimulated hormone (TSH), a hormone secreted by the pituitary, a gland just located under the brain. Another way to obtain elevated TSH levels is to perform intramuscular injection of recombinant human TSH, a hormone produced pharmaceutically. The goal of this study is to know whether the radioiodine uptake by the metastases is similar after rhTSH administration or after thyroid hormone withdrawal.
