Fecal Glucocorticoid Analysis: Non-invasive Adrenal Monitoring in Equids

Low plasma cortisol and hematologic abnormalities associated with essential fatty acid deficiency in man
Abstract:
A case of probable adrenal insufficiency (glucocorticoid only) with hematologic changes including eosinophilia, neutropenia, and red blood cell abnormalities developed in the course of prolonged, fat-free feeding. The coincident development of essential fatty acid deficiency was conformed by serum fatty acid profiles indicating the presence of abnormal amounts of eicosatrienoic acid, and a triene/tetraene ratio greater than 0.4; all these findings responded to fat repletion. The association of glucocorticoid deficiency, neutropenia, and eosinophilia with essential fatty acid deficiency has not been previously reported in humans.

Fat-soluble Vitamins
Fat-soluble vitamins, including vitamins A, D, E, and K, are required in minimal quantities, but their deficiencies can lead to severely abnormal physiological conditions. For example, vitamin A deficiency can cause night blindness, dry skin, delayed...
Hormones of the Adrenal Glands
The adrenal cortex, a powerhouse of hormone synthesis, generates over two dozen corticosteroid hormones. The zona glomerulosa produces mineralocorticoids, exemplified by aldosterone, influencing the electrolyte composition of body fluids. The synthesis of glucocorticoids such as cortisol and corticosterone...
Adrenal Gland Disorders
Adrenal insufficiency, characterized by insufficient cortisol and aldosterone production, leads to conditions like Addison's disease. This disorder, affecting the adrenal cortex, exhibits symptoms such as skin bronzing, dehydration, low blood pressure, fatigue, and weight loss. Congenital adrenal hyperplasia, a genetic ailment causing...
