Influence of adrenal cortex on exocrine pancreatic function
Gastroenterology
|July 1, 1982
Summary
Chronic adrenocortical insufficiency impairs exocrine pancreatic function, significantly reducing digestive enzyme and bicarbonate secretion. Glucocorticoid therapy largely reverses these pancreatic deficits, highlighting the adrenal cortex's crucial role.
Area of Science:
- Endocrinology
- Gastroenterology
- Pancreatic Physiology
Background:
- Chronic adrenocortical insufficiency affects multiple organ systems.
- The exocrine pancreas plays a vital role in digestion.
- Potential links between adrenal function and pancreatic exocrine secretion are not fully understood.
Purpose of the Study:
- To investigate the exocrine pancreatic function in patients with chronic adrenocortical insufficiency.
- To compare pancreatic function between patients and healthy controls.
- To assess the impact of glucocorticoid replacement therapy on pancreatic function.
Main Methods:
- Studied 8 patients with chronic adrenocortical insufficiency and 12 healthy controls.
- Administered secretin and caerulein to stimulate pancreatic secretion.
- Measured bicarbonate, lipase, and chymotrypsin output.
Main Results:
- Patients showed significantly reduced secretion of bicarbonate (42% less), lipase (66% less), and chymotrypsin (53% less) compared to controls.
- Chronic glucocorticoid substitution therapy normalized pancreatic function.
- Adrenal cortex plays a critical role in maintaining exocrine pancreatic function.
Conclusions:
- Adrenal insufficiency severely impairs exocrine pancreatic secretion.
- Glucocorticoid therapy is effective in restoring pancreatic function.
- The adrenal cortex is essential for normal human exocrine pancreatic function.

01:17Anatomy of the Adrenal Glands
The adrenal or supra-renal glands, situated above the kidneys and aligned with the twelfth rib, are paired pyramid-shaped structures crucial for the body's stress response. During stress, these glands secrete hormones vital for adaptive physiological reactions.
These glands possess a distinctive yellow tinge due to the stored cholesterol and fatty acids required for hormone synthesis. They are encased in a fibrous capsule and cushioned by fat.

01:31Hormones of the Adrenal Glands
Adrenal hormones play a pivotal role in maintaining the body's electrolyte balance and orchestrating responses to stress, showcasing the intricate functions of the adrenal cortex and medulla.
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...

01:27Adrenal Gland Disorders
Adrenal gland disorders manifest when the production of adrenal hormones deviates from the norm, resulting in either excessive or insufficient concentrations.
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...

01:16Cells and Secretions of the Pancreas
The pancreas, a vital organ within the abdominal cavity, plays dual roles in the digestive and endocrine systems, collaborating with exocrine and endocrine cells to maintain optimal digestion and blood sugar levels.
Exocrine function is carried out by acinar cells, organized into clusters known as acini. These cells contribute to digestion by releasing substantial quantities of enzyme-rich, alkaline digestive juices.
Concurrently, the dispersed clusters of endocrine cells throughout the...

01:16Hormones Regulating Blood Glucose
Insulin is released by beta cells of the pancreas when blood glucose levels are high. It facilitates glucose absorption and utilization in insulin-dependent cells with insulin receptors on their plasma membranes. Insulin promotes glucose uptake by increasing the number of glucose transport proteins in the cell membrane, allowing glucose to enter the cell. As a result, glucose utilization and ATP production are enhanced.
In addition to accelerating glucose uptake and utilization, insulin has...

01:19Cushing Syndrome II: Pathophysiology
Cortisol production is normally governed by the hypothalamic–pituitary–adrenal (HPA) axis, which maintains hormonal balance through tightly regulated feedback mechanisms. Disruption of this regulatory system is central to the development of Cushing syndrome, whether the excess cortisol originates from external medications or internal pathology. Persistent cortisol elevation alters metabolism, immune function, and endocrine signaling, producing the characteristic clinical features of the...
