Hypothalamo-pituitary-adrenal axis activity after intracranial catastrophies: what is enough?
This commentary on a paper by Bendel and colleagues in the previous issue of Critical Care describes the difficulty in assessing the sufficiency of adrenal responses to endogenous, stress-induced adrenocorticotropic hormone (ACTH) release by the pituitary or to exogenous ACTH administration in the critically ill patient in general, and after subarachnoid hemorrhage in particular. It is argued t...
متن کاملSpinal and supraspinal analgesic effects of Nimodipine : The role of Hypothalamo-Pituitary-Adrenal(HPA) axis .
Nimodipine, an L-type calcium channel blocker, can induce analgesia. However, it is not clear that this analgesic effect is at the level of spinal or supraspinal pain pathway. In addition, it has been reported that the analgesic effect of nifedipine, another L-type calcium channel blocker is related to the HPA axis, but there is no report indicating the role of this axis in the analgesic eff...
متن کاملHypothalamo-pituitary-adrenal axis and adrenal function before and after ovariectomy in premenopausal women.
The hypothalamo-pituitary-adrenal (HPA) axis is modulated by sex hormones. Few data exist on the relation between acute estrogen deficit and HPA axis response to corticotropin-releasing hormone (CRH). The effects of a sudden drop in estradiol levels on basal and CRH-stimulated levels of ACTH, cortisol, testosterone, androstenedione and 17-hydroxyprogesterone (17-OHP) were assessed in nine preme...
متن کاملStudy of hypothalamo pituitary adrenal axis in frail elderly subjects.
BACKGROUND Frail elderly people are at increased risk of death and disability from minor environmental stresses such as infection because they do not have the reserves to respond and maintain adequate homeostasis Studies have shown that elderly patients had a significantly smaller response to ACTH stimulation test. Due to paucity of data regarding HPA axis functioning in frail elderly in Indian...
متن کاملIntroduction to the Hypothalamo- Pituitary-adrenal (hpa) Axis
OBJECTIVES: • Identify appropriate hypothalamic factors that control the secretion of each of the anterior pituitary hormones, and describe their route of transport from the hypothalamus to the anterior pituitary. • Contrast the anterior and posterior pituitary lobes with respect to cell types, vascular supply, development, and innervation (hypothalamic). • Diagram the short-loop and long-loop ...
