OBJECTIVE Patients who appear to have both stimulating and blocking TSHR autoantibodies in their sera have been described, but the two activities have not been separated and analysed. We now describe the isolation and detailed characterization of a blocking type TSHR monoclonal autoantibody and a stimulating type TSHR monoclonal autoantibody from a single sample of peripheral blood lymphocytes....

Differential display (DD) PCR (Liang and Pardee, 1992) is a recently described technique to identify genes whose expression has changed during a biological process. We used this method to detect genes thyroid stimulating hormone-dependently regulated in a rat thyroid cell line, because thyroid stimulating hormone (TSH) is the most important hormone for cell proliferation and differentiation inc...

OBJECTIVE The objective of this study is to evaluate the link between excess iodine intake as evidenced by increased urinary iodine excretion (UIE) and autoimmune thyroiditis in children and to assess the correlation between UIE and thyroid microsomal antibody (thyroid peroxidase [TPO]) titers in children. MATERIALS AND METHODS All children with goiter between age group 6 and 12 years, were s...

On the basis of strong research evidence, hyperthyroidism is a rare but potentially serious disorder in childhood that, if uncontrolled, can lead to a wide range of complications, including effects on growth and development. • On the basis of strong research evidence, Graves' disease is the most common cause of hyperthyroidism in children, accounting for greater than 95% of cases. It is caused ...

Abstract Neonatal thyrotoxicosis is mostly caused by the transplacental passage of maternal thyroid stimulating hormone (TSH) receptor antibodies (TRAb) to fetus. Although rare and transient, this condition may be associated with significant morbidity mortality if not diagnosed treated in an appropriate timely manner. Anti-thyroid drugs are main therapy. Here, we report a preterm newborn that p...

Hashimoto’s patients have in some cases both stimulating and blocking antibodies [2, 3]. It stands to reason that if the patient is hypothyroid, then blocking antibody avidity and/ or titer would dominate irrespective of the presence of stimulating antibodies. There is a growing list of publications that show the prevalence of TSHR stimulating autoantibodies in HT patients using bioassays. Wall...

Graves’ Disease (GD) is the most common form of hyperthyroidism. It affects 3% female patients and 0.5% male usually between age 30-60. cause 80% hyperthyroid cases in USA. The pathogenesis disease complex autoimmunity plays a key role. antibodies stimulating thyrotropin receptor (TRAb) lead to uncontrolled Thyroid-stimulating Hormone (TSH) overproduction thyroid hormones from overactive gland....

Indices of thyroid function were measured in 97 preterm infants at birth and at 5, 10, and 15 days of age. Triiodothyronine uptake, free thyroxine index, thyroxine, free thyroxine, triiodothyronine, reverse triiodothyronine, and thyroxine binding globulin values at birth correlated with gestational age, whereas thyroid stimulating hormone values did not. Treatment with steroids prenatally had n...

Osteoporosis is increasingly found in the elderly and senile, maintaining its enormous medical social significance. The effect of hormones on bone metabolism beyond doubt. However, currently data sex tissue prevails. As for other hormones, sometimes, there are conflicting opinions. aim study: Based published data, to study contribution endocrine system development osteoporosis elderly. Material...
