remains clear is the definitive treatment for ALD. Thomas Starzl, the father of modern transplantation, first de- scribed LT as a treatment modality for patients with cirrhosis due to alcohol in a series written in 1988. 13. It has been widely adopted since that time and remains a valuable therapy for those patients in need. DIAGNOSIS The diagnosis of ALD is based on a combination of features, in- cluding a history of significant alcohol intake, clinical evidence of liver disease, and supporting laboratory abnormalities. Unfor- tunately, the ability to detect these is constrained by patient and physician factors, as well as diagnostic laboratory shortcomings. Denial of alcohol abuse and underreporting of alcohol intake are common in this population, and physicians tend to underestimate alcohol-related issues and rarely make specific recommendations. Both the physical exam findings and laboratory evidence for ALD may be non-diagnostic, especially in patients with mild ALD or early cirrhosis, but the clinician must have a low threshold to raise the issue of possible ALD and stress the importance of abstinence from alcohol. The gold standard for diagnosis remains a liver bi- opsy, but is rarely needed given an appropriate history, imaging characteristics and elimination of other etiologies of end-stage liver disease. THE COMPLEXITY OF ALCOHOL More importantly, about one in five patients will return to harmful levels of drinking, and a third of those will progress to allograft cirrhosis. 17-18. Recurrent cirrhosis due to alcohol after liver trans- plant tends to eliminate patients from consideration for re-trans- plantation and outcomes are poor. 18. There are various risk scores and tools under investigation in an attempt to predict which pa- tients will return to harmful drinking after LT. TREATMENT ABSTINENCE At the Trager Transplant Center in Louisville, liver transplant re- ferral patients are evaluated by a multidisciplinary team includ- ing hepatologists, surgeons, nurse coordinators, dietitians, social workers, and psychologists. Patients are discussed weekly at a Pa- tient Selection Committee which ultimately decides on transplant candidacy. We do require six months of sobriety prior to listing for transplantation and patients undergo random drug and alco- hol screens to assure compliance with their sobriety. Patients are also encouraged to take part in either Alcoholics Anonymous or another intensive outpatient program (IOP), but this is not a re- quirement prior to transplant as long as they demonstrate a com- mitment to sobriety. Many of our patients have had excellent suc- cess with The Healing Place, a local, nationally recognized, long- term social model recovery program. After LT, we do not have any required drug screens or sobriety program involvement, but patients are intensively followed with regular outpatient visits,as are all post-LT patients. Abstinence is the most important therapeutic intervention for pa- tients with ALD. Abstinence has been shown to improve the out- come histological features of hepatic injury, decrease progression to cirrhosis, and to improve survival at all stages in patients with ALD. This can be relatively rapid, and in 66% of patients abstain- ing from alcohol, significant improvement was observed in three months. 14 There is a concern that a large number of patients with ALD are never referred for transplant evaluation and are essentially “ruled out” for their drinking history. Therefore the depths of the problem with ALD may be vastly under reported. Our center does not require six months of sobriety prior to evaluation and will work with patients on seeking appropriate addiction resources to reach the requisite sobriety point before listing. It is for that reason that most liver transplant programs in the United States have adopted a “six month rule,” which requires pa- tients with alcoholic cirrhosis to demonstrate six months of so- briety prior to undergoing transplantation. There are centers that will offer liver transplantation to selected patients with severe al- coholic hepatitis in the acute setting who are unlikely to survive to the six month mark. It should be noted that sobriety is not a requirement for listing or liver transplant by the United Network for Organ Sharing (UNOS); that decision is left to the discretion of the listing transplant center. ETHICS OUTCOMES AND RECIDIVISM Post-transplant outcomes for those patients with ALD are compa- rable to those who have undergone LT for other etiologies. Relapse to alcohol use and abuse after transplant is a unique challenge to this population. Between 10-90% of patients return to some form of alcohol use depending on how the researchers defined “use.” 16. The ethical debate surrounding LT for ALD remains a point of contention nationwide. Some argue that given the limited resourc- es surrounding organ availability, that use for ALD is not appro- priate. A potential drop in donations with greater publicity of ALD transplants is often suggested as an argument against transplant for this disease, but this has never been supported. STIGMA AND PERSONAL RESPONSIBILITY FOR HEALTH Transplantation for patients with ALD has generated widespread debate among the general public, health care professionals, pa- tients, living donors, and family members. A commonly expressed concern pertains to a patient’s personal responsibility for his or her own health. Specifically, opponents argue that, in ALD, liv- er damage is self-induced—alcoholism leading to end-stage liver (continued on page 22) OCTOBER 2019 21
