Binge Drinking Can Amplify Liver Damage

Emerging research suggests binge drinking can lead to changes in liver proteins that may result in cirrhosis and cancer.

University of Missouri researchers discovered binge drinking or over-consumption of alcohol is especially dangerous among those who already drink a lot.

“We know that chronic alcohol use is damaging to the liver, but binge drinking amplifies that damage,” said Shivendra Shukla, Ph.D., lead author of the study.

Excessive alcohol use is one of the most common causes of chronic liver failure. Long-term liver damage from alcohol use is irreversible.

Excessive alcohol use is also associated with high blood pressure, heart disease, stroke, cancer, and digestive problems.

Binge drinking is defined as a pattern of drinking that brings a person’s blood alcohol concentration to 0.08 grams percent or above. This typically happens when men consume five or more drinks or women consume four or more drinks over a two-hour period.

Binge drinking appears to cause genetic changes in tissues of the liver.

“Our latest research shows that epigenetic modifications in histone structures occur within the liver as a result of heavy binge drinking,” Shukla said.

“Epigenetic alterations are changes in genes that are not caused by changes in the DNA sequence or genetic code.”

Histones are proteins that act like a spool to compact and organize the thread-like DNA strands that wrap around them. Histones work to protect the DNA strand and help it function correctly.

Although histone modification does occur naturally, Shukla and his team found that binge drinking results in unnatural modifications to histones.

A modification of histones adversely affect how a person’s genetic code is interpreted and how it is regulated.

“Every response in the body is due to alterations in proteins,” Shukla said. “Binge drinking is an environmental trigger that negatively affects histones by altering the correct binding of DNA.

“The result is unnecessary replication in the copied structure. This initially causes inflammation and damage to the cells as they form, but it is also eventually the cause of more serious diseases such as cirrhosis and cancer.”

Researchers believe the discovery could lead to treatments for alcohol-related liver diseases.

The liver is the main metabolic site in the body and is therefore the first to be damaged by binge drinking. However, damage to the liver also harms other major organs such as the heart, kidney, blood vessels, and the brain.

“It is important to specify that binge drinking should not be associated only with liver damage,” Shukla said.

“Binge drinking can create an inflammatory response in the liver that is like a cluster bomb, sending out various damaging signals to other organ systems in the body. If those organs are working at a lower level of function, then a whole host of physiological processes are affected as a consequence of binge drinking.”

Shukla believes excessive alcohol consumption with a binge drinking pattern is an emerging public problem.

In the U.S., the Centers for Disease Control and Prevention report approximately one in six adults binge drinks about four times each month.

“This is not a problem that is going away,” said Shukla. “It is actually growing. More work is needed on the research we are doing, but findings such as these are very promising and may lead to future treatments for alcohol-related liver damage.”

The study was recently published in the journal Hepatology International.
