BACKGROUND Environmental exposure of infants to perchlorate, thiocyanate, nitrate, might interfere with thyroid function. U.S. women with higher background perchlorate exposure have higher thyroid-stimulating hormone (TSH) and lower thyroxine (T4). There are no studies with individual measures of thyroid function and these goitrogens available in infants. OBJECTIVE We examined the association...
BACKGROUND Thyroidectomized patients need variable doses of levothyroxine (LT4) to obtain target thyroid-stimulating hormone (TSH) levels. Individual feedback set-points have been hypothesized and the influence of several genes in the regulation of the pituitary-thyroid axis has been demonstrated. OBJECTIVES We hypothesized that genetic variants of the TRHR gene could be associated with a dif...
There have been many observations describing morphological and biochemical alterations in the thyroid after administration of thyroid-stimulating hormone. The hormone has been shown to increase oxygen consumption (l-3), incorporation of P32 into phospholipids (4), iodide uptake (5), the formation of iodotyrosines (6, 7), and glucose oxidation (8, 9) by thyroid tissue in vitro. There have recent...
Eight children with cystinosis (3 with renal transplants, 2 on maintenance haemodialysis, 2 with chronic renal failure, and one with normal renal function) were studied for evidence of hypothyroidism, and compared with a control group of children with chronic renal failure due to other causes. Abnormal thyroid function was present in all the cystinotic patients: thyroxine (T4) low in 1, free th...
BACKGROUND Hepcidin is a master regulator of iron metabolism that inhibits the transport of iron out of enterocytes and macrophages. Thalassemia major (TM) is associated with some of the endocrine disorders. However, studies have yet to be conducted on the correlation of hepcidin with hormone levels and insulin resistance (IR) in patients with TM. OBJECTIVES In the present study, the correlat...
Background: Although there is little information about the prevalence of thyroid disorders in young women, but they are common Iraq. Objective: To hormones test abnormality females at reproductive age attending al-batool maternity teaching hospital Patients and Methods: This study involved 1570 female ages patients Al-batool Maternity Hospital Diyala Province, Serum levels T3, T4, TSH were meas...
Folate receptor α (FRα) autoantibodies (FRAAs) are prevalent in autism spectrum disorder (ASD). FRAAs disrupt folate transport across the blood-brain barrier by binding to the FRα. Thyroid dysfunction is frequently found in children with ASD. We measured blocking and binding FRAAs and thyroid-stimulating hormone (TSH), free thyroxine (T4) (FT4), total triiodothyronine (T3) (TT3), reverse T3 (rT...
The plasma concentration of a pituitary hormone is determined by the rate of secretion, degradation, and the volume of distribution of that hormone. Using a radioimmunoassay for human thyrotropin (TSH) and human TSH-(131)I, we have estimated the rates of degradation and distribution of TSH in man and calculated the rate of secretion. Either 0.5 or 5 mug of TSH-(131)I with specific activities of...
We recently described the direct effects of thyroid-stimulating hormone (TSH) on bone and suggested that the bone loss in hyperthyroidism, hitherto attributed solely to elevated thyroid hormone levels, could at least in part arise from accompanying decrements in serum TSH. Recent studies on both mice and human subjects provide compelling evidence that thyroid hormones and TSH have the opposite ...
