Alcoholic liver disease (ALD) is the second most common indication for liver transplants in the U.S. and Europe. Although reported survival rates after transplantation were similar between alcoholics and non-alcoholics (up to 60 percent at 7 years following transplant), concerns about alcohol relapse post-transplant have made the practice somewhat controversial, especially in light of the shortage of donor organs. To offset this risk, it is common practice to establish a 6 month period of abstinence from alcohol before listing a patient for liver transplant. Not only may improvement in liver function result, but higher rates of relapse have been reported in patients who have abstained for less than 6 months before undergoing transplantation. Although several previous studies analyzed the rate of alcohol relapse after liver transplantation and its influence on patient survival and transplant success, researchers had previously not studied patients for a longer follow-up period.
