Summary
High-dose glucocorticoids (GCs) disrupt glucose and lipid metabolism, leading to liver triglyceride deposition. Understanding these effects is crucial for managing GC treatment side effects and improving patient outcomes.
Area of Science:
- Endocrinology
- Metabolic Research
- Hepatology
Background:
- Glucocorticoids (GCs) are widely used for various diseases, often at high doses for extended durations.
- GCs are known to cause significant metabolic side effects, including insulin resistance and hepatic lipid accumulation.
Purpose of the Study:
- To review the metabolic pathways of hepatic lipid deposition and removal affected by excess glucocorticoids.
- To examine the role of 11β-hydroxysteroid dehydrogenases in intracellular cortisol levels and their impact on metabolism.
- To discuss the influence of GC treatment on osteocalcin expression and insulin sensitivity.
Main Methods:
- Literature review of metabolic pathways involved in glucocorticoid-induced liver lipid deposition and removal.
- Analysis of the impact of glucocorticoids on appetite, gluconeogenesis, lipogenesis, and fatty acid metabolism.
- Examination of the role of specific enzymes (11β-HSD1/2) and hormones (osteocalcin) in mediating these effects.
Main Results:
- Excess glucocorticoids stimulate lipid deposition via increased caloric intake, gluconeogenesis, de novo lipogenesis, and enhanced free fatty acid uptake by the liver.
- Glucocorticoids inhibit fatty acid beta-oxidation and modestly stimulate VLDL synthesis, contributing to hepatic lipid accumulation.
- Intracellular cortisol levels, modulated by 11β-HSD1/2, and osteocalcin expression are key factors in GC-induced metabolic disturbances.
Conclusions:
- Glucocorticoid excess significantly alters hepatic lipid metabolism, promoting triglyceride deposition through multiple pathways.
- Understanding the dose-response and duration-dependent effects of GCs is vital for mitigating liver fat accumulation.
- Further research into the reversibility of GC-induced hepatic steatosis and the interplay with hormones like osteocalcin is warranted.

350
Glucocorticoids, a class of anti-inflammatory drugs, are pivotal in treating moderate to severe Crohn's disease by inducing remission. They exhibit their anti-inflammatory action by inhibiting the production of inflammatory cytokines such as tumor necrosis factor (TNF)-α, interleukin (IL)-1, and chemokines like IL-8. In addition, they reduce the expression of inflammatory cell adhesion molecules and inhibit gene transcription of nitric oxide synthase, phospholipase A2, cyclooxygenase-2...

744
Incretins include glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP), which stimulate insulin secretion post-meals. In type 2 diabetes, GIP's efficacy is reduced, making GLP-1 a viable drug target. GIP originates from preproGIP.
GLP-1, when administered in high doses intravenously, triggers insulin secretion, inhibits glucagon release, slows gastric emptying, reduces food intake, and restores normal insulin secretion. However, its rapid inactivation by...

01:15Hypoglycemia and Glucagon
718
Without prolonged fasting, healthy individuals maintain blood glucose levels above 3.5 mM due to a well-adapted neuroendocrine counterregulatory system that effectively prevents acute hypoglycemia, a potentially life-threatening condition. The primary clinical scenarios for hypoglycemia encompass diabetes treatment, inappropriate production of endogenous insulin or insulin-like substances by tumors, and the use of glucose-lowering agents in non-diabetic individuals. Notably, hypoglycemia in the...

01:24Chronic Pancreatitis I: Introduction
608
The pancreas, an elongated and flat gland situated behind the stomach, serves a vital function in digesting food and managing blood sugar levels.
Pancreatitis is the inflammation of the pancreas, which occurs when the immune system becomes active and causes swelling, pain, and disruptions in organ function. Pancreatitis can manifest as either an acute or chronic condition.
Acute pancreatitis arises suddenly and lasts for a brief duration, while chronic pancreatitis is a long-term affliction...

Lipids also are sources of energy that power cellular processes. Like carbohydrates, lipids are composed of carbon, hydrogen, and oxygen, but these atoms are arranged differently. Most lipids are nonpolar and hydrophobic. Major types include fats and oils, waxes, phospholipids, and steroids.
Fatty acids are catabolized in a process called beta-oxidation, which takes place in the matrix of the mitochondria and converts their fatty acid chains into two-carbon units of acetyl groups. The acetyl...

Carbohydrate metabolism is a fundamental biochemical process that ensures a constant supply of energy to living cells. The most important carbohydrate is glucose, which can be broken down via glycolysis to enter into the Krebs cycle and eventually lead to the production of ATP through oxidative phosphorylation.
