Alcohol Research : Current Reviews
|April 19, 2021
Summary
Chronic alcohol use damages multiple organs, including the liver, heart, and pancreas. Abstinence can lead to significant functional recovery in many organs, especially the liver.
Area of Science:
- Toxicology
- Gastroenterology
- Cardiology
- Endocrinology
- Hepatology
Background:
- Chronic alcohol consumption, diagnosed as alcohol use disorder, leads to widespread organ damage.
- The liver is particularly vulnerable to alcohol-induced injury.
- Heavy drinking affects the gastrointestinal tract, pancreas, heart, and bone.
Purpose of the Study:
- To review the effects of chronic alcohol use on multiple organs.
- To explore the potential for organ recovery after alcohol cessation (abstinence).
- To discuss ethanol metabolism and its role in organ injury.
Main Methods:
- Review of human studies on heavy alcohol use.
- Analysis of animal models of chronic ethanol feeding.
- Examination of organ-specific ethanol metabolism and damage.
Main Results:
- Alcohol causes structural damage across various organs.
- The liver demonstrates significant regenerative capacity upon abstinence.
- Other organs also show potential for functional recovery after cessation.
- Ethanol metabolism influences the severity of organ injury.
Conclusions:
- Chronic alcohol consumption causes multi-organ damage.
- Abstinence is crucial for organ recovery, with varying degrees of success.
- The liver's regenerative potential is a key factor in recovery.
- Understanding ethanol metabolism aids in predicting and managing organ injury.

3.7K
The liver is an important organ in vertebrates that plays an essential role in metabolism. It is also responsible for storing and redistributing nutrients such as carbohydrates, fats, and vitamins in the body. Additionally, the liver releases bile salts which are critical for digesting food and eliminating toxic metabolites from the body.

The liver comprises four major types of cells— hepatocytes, stellate, Kupffer, and sinusoidal endothelial cells. The hepatocytes are...

01:23Drug Elimination: Non-Renal Routes
2.7K
The liver plays a pivotal role in eliminating drugs and their metabolites, primarily through a process known as biliary excretion. This process involves the hepatocytes, the primary cells in the liver that generate bile. A range of transporters actively expels polar drugs or hydrophilic drug metabolites into the bile, which transports the drugs and metabolites into the small intestine. From here, they are eventually expelled from the body through feces. In some instances, the original drug or a...

01:27CNS Depressants: Alcohol and Nicotine
632
Ethanol, a clear colorless alcohol, has been consumed by humans for millennia, but its effects on the body are far from benign. At lower doses, it induces decreased inhibitions and loquaciousness, leading to its social appeal. However, it can cause severe consequences at higher doses, such as coma and respiratory depression, due to its zero-order elimination kinetics. Chronic ethanol abuse wreaks havoc on multiple organ systems, particularly the CNS and the liver. Abrupt cessation of ethanol...

01:17Hepatic Drug Excretion: Enterohepatic Cycling
2.1K
Enterohepatic cycling involves the active secretion of drugs and their metabolites into the bile via transporters in the canalicular membrane of hepatocytes. This secretion is an integral part of the digestive process, releasing these substances into the gastrointestinal (GI) tract.
Post-release drugs and metabolites can be reabsorbed into the body from the intestine. For conjugated metabolites like glucuronides, reabsorption requires enzymatic hydrolysis by intestinal microflora. This...

01:18Metabolic States of the Body: The Postabsorptive State
873
The postabsorptive state usually starts about four hours after a meal and lasts until the next meal is eaten. During this time, the digestive system stops absorbing nutrients, and the body uses stored energy reserves to maintain stable blood glucose levels.
Initially, glycogen stored in the liver is broken down to release glucose into the bloodstream, while glycogen in the muscles is broken down to supply glucose for energy directly within the muscle cells. As glycogen stores diminish,...

01:10Drug Excretion: Miscellaneous Routes
184
Drug excretion involves various organs, including the liver, intestines, skin, and eyes. In the case of drugs or toxins, they can be actively secreted into bile by transporters in the hepatocyte's canalicular membrane. These substances enter the GI tract during digestion and may be reabsorbed into the body from the intestine. This process, known as enterohepatic recycling, can significantly prolong the presence and effects of a substance in the body. To interrupt this cycle, specific...
