Elevated thyroid-stimulating hormone (TSH) levels often accompany impaired LV diastolic function and subtle systolic dysfunction in subclinical hypothyroidism (sHT). These cardiac dysfunctions are characterized by increases in mean aortic acceleration and pre-ejection/ejection time ratios. To explore the mechanism underlying these pathologies, we investigated the effects of TSH on sarcoplasmic ...
UNLABELLED Elevated thyroid-stimulating hormone (TSH) was discovered by routine neonatal screening in a newborn with no clinical symptoms. Thyroid function tests were repeated and confirmed a high TSH value but normal total thyroxine (T4) and triiodothyronine (T3). However, the mother also had elevated serum TSH with normal levels of T4 and T3. The results suggested a transmitted maternal inter...
We present the first case of iatrogenic hypothyroidism as a result of compounded thyroid hormone (T4/T3) therapy. The thyroid replacement was changed from 175 µg levothyroxine (LT4) to 57/13.5 µg compounded T4/T3 daily in order to improve the T3 level, despite normal thyroid-stimulating hormone (TSH). This resulted in clinical manifestations of hypothyroidism and high TSH level (150 µIU/mL). Si...
Objective This study analyzed the effectiveness of the thyroid-stimulating hormone (TSH) as a predictor of insulin resistance (IR) and its association with the clinical and metabolic parameters of women with polycystic ovary syndrome (PCOS) without overt hypothyroidism. Study Design A cross-sectional study was performed. Women with PCOS and without overt hypothyroidism (n = 168) were included. ...
We evaluated an immunoenzymatic assay (Abbott HTSH EIA) for thyrotropin (TSH) as a tool for detecting hyperthyroidism and for monitoring thyroid hormone suppressive therapy in patients with nodular goiter, thyroid carcinoma, and hypopituitarism. We also tested with thyroliberin (TRH), to determine the correlation between peak and basal TSH in suppressed patients. For comparison, we used a noneq...
BACKGROUND Accurate measurement of free thyroid hormones is important for managing thyroid disorders. Ultrafiltration liquid chromatography tandem mass spectrometry (LC-MS/MS) can reliably measure the concentrations of small molecules, including thyroid hormones. Our study was designed to compare free thyroid hormone measurements performed with immunoassay and LC-MS/MS. METHODS We studied the...
We encountered a case with hyperthyroidism at the age of 14 who had been diagnosed with congenital hypothyroidism (CH) and had received thyroid hormone replacement therapy. At the age of 16 d, the patient was referred to our hospital because of positive results at neonatal screening for CH. Serum level of TSH was 91.0 μU/ml and serum level of T4 was 6.9 μg/dl. The patient was diagnosed as havin...
The relationship between thyroid-stimulating hormone (TSH) and hyperlipidemia is still a topic of debate. We aimed to explore the impact of gender and age on the association between serum TSH and lipid profile in a large cohort of Chinese.This cross-sectional study enrolled 13,915 participants (8565 male, 5350 female), who self-reported as healthy without any known previous diseases. Clinical d...
Resistance to thyroid hormone is an uncommon condition. We report the clinical and laboratory findings of a case with both resistance to thyroid hormone and, a reduced capacity to produce and respond to thyroid hormone. RTH is a disorder characterized by elevated circulating thyroid hormones, state of non-suppressed pituitary TSH secretion and refractoriness to hormone action in peripheral tiss...
Studies were conducted to determine whether thyroid-stimulating hormone (TSH; thyrotropin), a hormone known to increase cytosol concentrations of cyclic AMP, also stimulates the formation of inositol phosphates in thyroid cells. TSH and noradrenaline both stimulated [3H]inositol phosphate formation in a concentration-dependent manner in the rat thyroid cell line, FRTL-5 cells, which had been pr...
