New Cutoffs for the Biochemical Diagnosis of Adrenal Insufficiency after ACTH Stimulation using Specific Cortisol Assays

open access: yesJournal of the Endocrine Society, 2021
Context The normal cortisol response 30 or 60 minutes after cosyntropin (ACTH[1–24]) is considered to be ≥18 μg/dL (500 nmol/L). This threshold is based on older serum cortisol assays.

Dynamics of ACTH and Cortisol Secretion and Implications for Disease

open access: yesEndocrine reviews, 2020
The past decade has seen several critical advances in our understanding of hypothalamic–pituitary–adrenal (HPA) axis regulation. Homeostatic physiological circuits need to integrate multiple internal and external stimuli and provide a dynamic output ...

ACTH more than 2000 pg/ml; is it immunoassay interference or another matter?

open access: yesJournal of Pathology of Nepal, 2023
Starting rifampicin in patients with Addison’s disease or adrenal tuberculosis may precipitate an adrenal crisis as a result of the induction of CYP 3A4 which in turn leads to increased breakdown of cortisol.

Arx expansion mutation perturbs cortical development by augmenting apoptosis without activating innate immunity in a mouse model of X-linked infantile spasms syndrome

open access: yesDisease Models & Mechanisms, 2020
X-linked infantile spasms syndrome (ISSX) is a clinically devastating developmental epileptic encephalopathy with life-long impact. Arx(GCG)10+7, a mouse model of the most common triplet-repeat expansion mutation of ARX, exhibits neonatal spasms ...

Repeated restraint stress induced neurobehavioral and sexual hormone disorders in male rats

open access: yesAIMS Neuroscience, 2022
Several studies have demonstrated that depression include disruptions not only for mental human disorders but also their healthy living. Rodent-based behavioral tests and models are widely used to understand the mechanisms by which stress triggers ...

Gel chromatographic characterization of immunoreactive adrenocorticotropin in patients with ACTH hypersecretion [PDF]

open access: yes, 1989
We investigated the molecular size of circulating immunoreactive ACTH by gel chromatography in patients with ACTH hypersecretion due to various disorders of the hypothalamic-pituitary-adrenal axis.

Does an Analysis of the Pulsatile Secretion Pattern of Adrenocorticotropin and Cortisol Predict the Result of Transsphenoidal Surgery in Cushing’s Disease. [PDF]

open access: yes, 1993
The endocrinological, surgical, and histological findings of patients with ACTH-dependent Cushing's disease were correlated with the pulsatile secretion pattern of ACTH and cortisol and the outcome after transsphenoidal pituitary surgery.

Assay-Specific Spurious ACTH Results Lead to Misdiagnosis, Unnecessary Testing, and Surgical Misadventure—A Case Series

open access: yesJournal of the Endocrine Society, 2019
The proper clinical evaluation of pituitary and adrenal disorders depends on the accurate measurement of plasma ACTH. The modern two-site sandwich ACTH immunoassay is a great improvement compared with older methods but still has the potential for ...
