Active clinical trials for "Hyperthyroidism"

Clustering of various metabolic parameters including abdominal obesity, hyperglycaemia, low high-density lipoprotein cholesterol, elevated triglycerides and hypertension have been used worldwide as metabolic syndrome to predict cardiometabolic risk. Thyroid dysfunction impacts on various levels of these components. Recent evidence from HepG2 cells indicates that betatrophin, also known as TD26/RIFL/lipasin/ANGPTL8/C19orf80, a secreted protein that regulates glucose, lipid metabolism, and energy homeostasis, is induced by T3. However, the role of betatrophin in hyperthyroid patients is unknown. The objective was to study serum betatrophin levels in hyperthyroid patients and the association of serum betatrophin levels with hyperthyroidism.

The half-life of the parathyroid hormone is about 4min, blood pth test is use in operation to confirm that parathyroid tumor is removed. but the blood pth test is time consuming and unpractical in most of hospital. this study will compare the application of rapid PTH test paper in operation of hyperparathyroidism.PTH test were measured in operation in different way. it will test at the time of preoperation, 15 minutes after surgery, 1 hour after surgery and 24 hours after surgery. thus evaluate the reliability and accuracy of PTH test paper in evaluating the Miami principles with the linear relation of blood PTH and the PTH test paper method.

Because of the high iodine uptake in the stomach, radioactive iodine treatment for thyroid diseases (cancer or hyperthyroidism) or radioactive iodine administered for thyroid scan may be able to eradicate H.pylori infection from the stomach of patients infected with H.pylori. Also to test the hypothesis that CagA virulent strains of H.pylori are more common in patients with thyroid cancer than with other thyroid diseases.

This study aims to verify the clinical value of thyroid ultrasound with microvascular flow imaging in thyrotoxic patients for differential diagnosis between hyperthyroidism and thyroiditis. We intend to use the RS85 Ultrasound device manufactured by Samsung Medison. Graves' disease and painless thyroiditis/subacute thyroiditis are the main cause of thyrotoxicosis. Precise discrimination between Graves' disease and painless thyroiditis/subacute thyroiditis is clinically very important in determining treatment methods, such as the prescription of antithyroid drugs. Primary endpoint was to verify the value of vascularity index, defined by Blood pixel in range of image / Total pixel in range of image .Seondary endpoint was to verify the superiority value of Microvascular flow imaging to discriminate thyrotoxicosis patients compared with Color doppler/ Power doppler ultrasound imaging and conventional ultrasound imaging.

Thyroxin a vital hormone for life lot of body functions depend on proper functioning on pituitary thyroid axis. it exists in two major forms Thyroxine (T4) and (T3) , each of them containing two iodine atoms on their inner (tyrosine) ring. Synthesis of reasonable quantities of thyroid hormones requires adequate iodine intake to allow sufficient thyroidal uptake. The World Health Organization (WHO) recommendation for daily intake of iodine is 150 μg for children ≥12 years and adults, and 250 μg for pregnant and lactating women. However as we know optimum amount of iodine is required for normal pituitary thyroid axis like wise excessive intake may cause over functioning of axis hence over production of hormone that can be manifested both clinically and biochemically. This study is designed to observe the frequency of over hyperthyroidism in patients taking iodinated salt.

The purpose of this study is to find out the capacity of standardized uptake value (SUV) using single-photo emission computed tomography and computed tomography (SPECT/CT) in diagnosing Grave's Disease (hyperthyroidism).

Hypothesis: What is the natural course after treatment with radioactive iodine in patients with hyperthyroidism? What are the determinants for the development of acute hypo- or hyperthyroidism after treatment with radioactive iodine without antithyroid drugs?
