Alcohol looms as the leading cause of liver transplantation in the United States.

Approximately 30% of heavy drinkers (>5 drinks per day for men; >4 drinks per day for women) will develop advanced alcohol-associated liver disease (ALD).

A spectrum of disorders that includes steatohepatitis, cirrhosis, alcoholic hepatitis, and progressive fibrosis, ALD increases the risk for the advance of end-stage liver disease, liver failure, and hepatocellular carcinoma.

The only treatment option offering the potential for cure for these severe conditions is liver transplantation.

However, liver transplantation for individuals with alcohol-induced liver disease has a long history of controversy, extending to a time when alcohol abuse was considered a vice rather than a chronic disease.

As a result, since the 1980s, a tradition in the transplant community precludes many patients with advanced liver disease from live transplantation until they have been abstinent for at least six months, an interim thought to increase the likelihood of successful outcome.

A reconsideration of the six-month rule

However, as Jonathan Dante Nahas, MD, explains, patients with alcohol-associated hepatitis have a six-month mortality of up to 70%, meaning only a minority live to the six-month metric for transplant eligibility.

At the Penn Transplant Institute and elsewhere, this stark finding has spurred a reconsideration of specified periods of sobriety, and led to the adoption of new protocols for patients with ALD seeking liver transplantation.

“About 15 years ago, there was a landmark publication that came out of the New England Journal that looked at transplant without a prespecified period of sobriety, and found that patients who were transplanted in this manner could do well over the long term with great rates of survival and relatively low relapse rates that were not all that different from patients who had been abstinent for 6 months,” Dr. Nahas explains. “So this was a revolution in the field of liver transplant for ALD. And it was adopted at other centers across the world—specifically in the U.S., and right here at Penn.”

Dr. Nahas’ discussion embraces the parameters for candidacy for liver transplantation for individuals with ALD, as well as the physical and psychosocial aspects involved, considerations contributing to successful outcomes, and much else.
