Long-term outcomes of liver transplantation for alcohol-related liver disease.

BACKGROUND

Liver transplantation (LT) is being increasingly performed for alcohol-related liver disease (ALD). It is unclear whether the increasing frequency of LTs in ALD patients has a negative impact on deceased-donor (DDLT) allocation and whether the current policy of 6 months of abstinence before transplantation effectively prevents recidivism after transplantation or improves long-term outcomes.

METHODS

A total of 506 adult LT recipients, including 97 ALD patients, were enrolled. The outcomes of ALD patients were compared with those of non-ALD patients. The 97 ALD patients were further divided into group A (6-month abstinence) and group N (nonabstinence) based on the pretransplant alcohol withdrawal period. The incidence of relapsed drinking and the long-term outcomes were compared between the two groups.

RESULTS

The prevalence of LT for ALD significantly increased after 2016 (27.0% vs 14.0%; p < 0.01), but the frequency of DDLT for ALD remained unchanged (22.6% vs 34.1%, p = 0.210). After a median follow-up of 56.9 months, patient survival was comparable between the ALD and non-ALD patients (1, 3, and 5 years posttransplant: 87.6%, 84.3%, and 79.5% vs 82.8%, 76.6%, and 72.2%, respectively; p = 0.396). The results were consistent irrespective of the transplant type and disease severity. In ALD patients, 22 of the 70 (31.4%) patients reported relapsed drinking after transplantation, and the prevalence in group A had a higher tendency than that in group N (38.3% vs 17.4%, p = 0.077). Six months of abstinence or nonabstinence did not result in a survival difference, and de novo malignancies were the leading cause of late patient death in ALD patients.

CONCLUSION

LT achieves favorable outcomes for ALD patients. Six months of abstinence pretransplant did not predict the risk of recidivism after transplantation. The high incidence of de novo malignancies in these patients warrants a more comprehensive physical evaluation and better lifestyle modifications to improve long-term outcomes.
