Abstract:
We have studied the recovery of the hypothalamic-pituitary-adrenal (HPA) axis from inhibition by short-term, intravenous high-dose, corticosteroid therapy (IVHDCT) without subsequent oral replacement therapy in 10 patients with relapsing-remitting or progressive multiple sclerosis (MS) using the human corticotrophin-releasing hormone (hCRH) test. There was significant HPA suppression with profoundly decreased basal and peak plasma ACTH and cortisol levels 24 h after cessation of therapy. However, at 48 h the pituitary response was greatly enhanced with peak ACTH concentrations rising by more than 100% over baseline values in 7 of 10 patients. Basal and stimulated ACTH concentrations returned to pre-treatment levels at 120 h. Basal and stimulated plasma cortisol levels remained subnormal in 6 patients 120 h after IVHDCT. We conclude that IVHDCT without oral replacement therapy in MS patients is endocrinologically safe.

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.
