A 78-year-old Japanese man showed suppression of the hypothalamic-pituitary-adrenal axis during maximum androgen blockade (MAB) therapy including chlormadinone acetate (CMA) for prostate cancer. After stopping the MAB therapy, both the basal ACTH level and the response to CRH recovered. While no reports have indicated that CMA suppresses the hypothalamic-pituitary-adrenal axis in patients with ...

Inflammation-related dysregulation of the hypothalamic-pituitary-adrenal (HPA) axis is central to the course of systemic inflammatory response syndrome or sepsis. The underlying mechanisms, however, are not well understood. Initial activation of adrenocortical hormone production during early sepsis depends on the stimulation of hypothalamus and pituitary mediated by cytokines; in late sepsis, t...

Adrenal Insufficiency (AI) is defined as deficient production or action of glucocorticoids resulting from either a structural damage of adrenal glands, namely ‘‘primary adrenal insufficiency’’, or an impairment of the hypothalamic-pituitary axis or ‘‘secondary adrenal disease’’ [1]. Primary AI is rare in general population, with an annual incidence of approximately 6/million adults/year and pre...

The association between cortisol and adult attachment style, an important indicator of social relationships, has been relatively unexplored. Previous research has examined adult attachment and acute cortisol responses to stress in the laboratory, but less is known about cortisol levels in everyday life. The present study examined adult romantic attachment style and cortisol responses across the...

A pulsatile pattern of secretion is a characteristic of many hormonal systems, including the glucocorticoid-producing hypothalamic–pituitary–adrenal (HPA) axis. Despite recent evidence supporting its importance for behavioral, neuroendocrine and transcriptional effects of glucocorticoids, there has been a paucity of information regarding the origin of glucocorticoid pulsatility. In this review ...

The influences of age (4 to 12 wk), sexual maturity status, and sex on hypothalamic-pituitary-adrenal (HPA) axis responsiveness were investigated by measuring changes in peripheral basal levels of corticosterone (B) and responses to 10 min of physical restraint in a crush cage or injection of 1-24 adrenocorticotropic hormone (ACTH) in 2 genotypes of Japanese quail divergently selected for long ...

THE STRESS RESPONSE SYSTEM (SRS) has a central role in orchestrating physical and psychosocial development of both humans and nonhuman species (Ellis, Jackson, & Boyce, 2006; Korte, Koolhaas, Wingfield, & McEwen, 2005). For many organisms, the SRS contributes crucially to responding flexibly to environmental opportunities and challenges. One of the most remarkable features of the SRS is the wid...

Context. Transient secondary adrenal insufficiency (SAI) is an expected complication following successful adenomectomy of ACTH-secreting pituitary adenomas or unilateral adrenalectomy for cortisol-secreting adrenal adenomas. To date, no pharmacological therapy has been shown to hasten recovery of the hypothalamic-pituitary-adrenal (HPA) axis in this clinical scenario. Case Description. A 33-yea...
