Active clinical trials for "Thyroid Diseases"

The hypothesis is that the particular richness of ATC's microenvironment in TAMs creates a unique opportunity for using Tumor Necrosis Factor blockade during chemotherapy and radiotherapy in order to counteract tumor resistance to therapy.

Postprandial thermogenesis, or thermic effect of food are terms that describe the increase in utilization of energy by the human body following a meal. The mechanisms involved in this process are believed to differ according to the type of food consumed, whether fat, protein or carbohydrate. The bile acids (BAs), unique substances secreted by the gall bladder into the gut after a meal, play an important role in the absorption of fat and the management of cholesterol stores in the body. Recent studies suggest that BAs may also serve as regulators of energy expenditure (consumption) in the cells of our body by increasing the production of T3, an active form of thyroid hormone. T3 in turn is believed to increase the efficiency with which our bodies burn calories thereby generating heat. Although this process has been shown to be effective in rodents who demonstrated weight loss after treatment, the role of BAs in humans is poorly understood. Thus we do not know whether endogenous (produced by the body) or exogenous (taken as medication) BAs play a significant role in the maintenance of body weight. We hypothesize that, similarly to rodents, humans will respond to BAs by increasing energy expenditure via the production of the active form of thyroid hormone. This randomized, cross-over study will look at changes in thyroid hormones and energy consumption in response to stimuli of endogenous BA secretion including dietary content, and to the intake of pharmacological doses of bile acids. Following a two-day period of equilibration diet, 30 healthy volunteers will be randomly assigned to receive either a high-fat or high-carbohydrate isocaloric meal followed by a 6-hour metabolic chamber stay; the next day they will be crossed-over to the alternate intervention. During the following three days, the study subjects will again be randomized to receive either an intravenous injection of sincalide (the C-terminal octapeptide fragment of cholecystokinin) 0.04 mcg/kg or placebo and P.O. placebo, or I.V. placebo and 15 mg/kg of BA (ursodiol) with similar metabolic chamber stays and cross-over design. The data gathered from this study will provide greater insight into the physiological and molecular mechanism(s) regulating the relation between endogenous bile acid secretion and energy metabolism in response to meals, as well as the role of BAs per se on energy metabolism.

Graves thyrotoxicosis is a common autoimmune disease. Patients suffer at diagnosis from weight loss, increased heart rate and stress intolerance. Some patients have difficulties in regaining quality of life. Diagnosis is found through elevated thyroid hormones thyroxin, suppressed TSH (thyroid stimulating hormone) from the pituitary and elevated stimulatory antibodies, TRAb (thyrotropin receptor antibody) to the thyroid. Selenium is sparse in western Europe. This compound has important function in thyroid hormone metabolism and on the immune system. It is not known whether addition of selenium affects the well being of patients with Graves´thyrotoxicosis. The subject of this study is to investigate this

This study was conducted in patients with differentiated thyroid cancer who had undergone near-total thyroidectomy. After surgery patients were randomized to one of two methods of performing thyroid remnant ablation (use of radioiodine to remove any remaining thyroid tissue). One group of patients who took thyroid hormone medicine and were euthyroid [i.e. their thyroid stimulating hormone (TSH) levels are normal], and received injections of Thyrogen (0.9 mg daily on two consecutive days) followed by oral radioiodine. The second group of patients did not take thyroid hormone medicine so that they were hypothyroid (i.e. their TSH levels were high), and were given oral radioiodine. All patients received the same amount of radioactive iodine (100 mCi or 3.7 GBq of 131I). Approximately 8 months later, whole body scans were performed on all patients to learn whether the thyroid remnants had been successfully ablated. The safety profile of Thyrogen when used for radioiodine remnant ablation also was assessed. The Quality of Life, the radioiodine uptake and retention into the thyroid bed, as well as radiation exposure to the remainder of the body also were assessed in both groups of patients.

The purpose of this study is to determine the safety and toxicity of the combination of pazopanib and GSK1120212 in patients with solid tumors and identify the maximum tolerated dose (MTD) of this combination for phase II study.

In this study, we will test, using a randomized controlled trial design, whether the use of a computer-based decision aid (DA) may improve general knowledge and reduce personal decisional conflict in patients with early stage papillary thyroid cancer (PTC), when compared to usual care. Patients with early stage PTC will be required to have surgical pathologic criteria for which adjuvant RAI treatment may be considered optional.

The study investigates the impact on post-operative pain of the superficial cervical block with bupivacaine combined with subcutaneous infiltration of the incisional area in thyroid surgery under general anesthesia. In addition, cost savings using the cervical block are evaluated (due to reduced length of hospital stay). The study is prospective, randomized, double blind, and placebo-controlled. The study is performed at the Department of Surgery, Cantonal Hospital of St. Gallen.

The purpose of this study is to determine the use of 177Lu-PP-F11N for imaging and therapy of patients with advanced medullary thyroid carcinoma (MTC). 177Lu-PP-F11N is a gastrin analogon, binding to cholecystokinin-2 receptors. This receptors show an overexpression on more than 90 % of medullary thyroid carcinomas.

Objectives: The use of neuromuscular blocking agent may interfere with the function of intraoperative neuromonitoring (IONM) in thyroid surgery.

Thyroid gland surgery is one of the most commonly performed operations for either benign or malignant pathologies Pain related to thyroid surgery is of moderate intensity .which may be treated with NSAIDs or opioids. However, Opioids have many well-known undesirable effects, including postoperative nausea and vomiting, which are frequent after this type of procedure.
