To provide basic information on the normal functioning of the hypothalamus-pituitary-adrenal axis in relation to pubertal development, growth (weight and height), body composition, and gender and to obtain reference data for serum cortisol concentrations in children, we investigated the basal circadian rhythm of serum cortisol in a group of 235 healthy children (162 boys and 73 girls). The age ...

Liquid chromatography-tandem mass spectrometry (LC-MS/MS) was used to measure 6 metabolic compounds of the adrenocorticosteroid pathway simultaneously on residual specimens from patients who had previously been previously diagnosed, on the basis of immunoassays, as having congenital adrenal hyperplasia (CAH), 11 beta-hydroxylase deficiency, 21-hydroxylase deficiency, or Addison disease (adrenal...

The objective of this study was to evaluate the influence of low-dose combined oral contraception (COC) on basal and stimulated (1 microg ACTH test) levels of serum and salivary cortisol (F), cortisone and on basal serum cortisol binding globulin (CBG), adrenocorticotropic hormone (ACTH), dehydroepiadrosterone (DHEA) and calculated free cortisol in healthy young women. Three-month administratio...

Background Certain studies suggest that percutaneous absorption of topical steroids may cause suppression of hypothalamic-pituitary-adrenal axis (HPAA) in atopic dermatitis (AD) patients. This study aimed to investigate the basal serum cortisol, adrenocorticotropic hormone (ACTH), and IgE levels in patients with AD and their correlation with the disease severity. Methods Levels of basal serum...

Rationale: The aim was to prospectively examine adrenal function including cosyntropin stimulation and its prognostic value in patients with moderate CAP. Methods: 59 consecutive adult patients hospitalised at normal ward because of CAP were enrolled. A cosyntropin stimulation test was performed and serum concentrations of CRP, PCT, IL-6, TNFα, ACTH, cortisol, dehydroepiandrosterone (DHEA) and ...

The present exposition was designed to evaluate blood serum changes in tiger grouper, Epinephelus fuscoguttatus in response to changes in water temperature and salinity. Uniformly sized fingerlings were randomly distributed into different groups at fifteen fish per tank, in two replicates. Each group represented experimental fishes subjected to water temperatures of 18, 24, 28 and 30°C (control...

A micro-scale method is presented for measurement of cortisol. Serum or plasma, 2 microliter, is diluted with buffer and the solution heated at 60 degrees C in the presence of high-affinity antibody and [3H] cortisol. Corticosteroid-binding globulin in the serum is denatured, releasing cortisol and making it available to the antibody, which is stable during the incubation. After cooling, ammoni...

We compared results obtained by (a) chemical (spectrophotometric) and competitive protein-binding assays for serum corticosteroids, and (b) competitive protein-binding and radioimmunoassay, with and without CCI-4 extraction, for serum cortisol. The two corticosteroid methods gave identical results. Radioimmunoassay with and without a CCI-4 extraction step gave identical results for cortisol. Co...
