ABSTRACT
BACKGROUND: Opioids are generally discouraged and used sparingly in liver transplant (LT) candidates prior to LT. This study examined the relationship between opioid use at the time of LT and graft and patient survival following transplantation. METHODS: A retrospective single center cohort study of LT recipients from June 2012 to December 2019 was performed. Primary outcomes were graft and patient survival, analyzed with the Kaplan-Meier method and Cox proportional hazards models; primary predictor was active opioid prescription at LT. RESULTS: 751 LT recipients were included; 16% had an opioid prescription at LT. Post-transplant death was significantly greater in opioid users (pvalue<0.001). In a multivariable Cox model examining predictors of death, opioid use remained associated with a significant increase in the risk of death (HR 2.4 CI 1.5-4.0, p < 0.001) even after controlling for other factors. CONCLUSION: Opioid use at LT is associated with a markedly increased risk of death following transplant.

BACKGROUND: The use of living donor liver transplantation (LDLT) for primary liver transplantation (LT) may quell concerns about allocating deceased donor organs if the need for retransplantation (re-LT) arises because the primary LT did not draw from the limited organ pool. However, outcomes of re-LT after LDLT are poorly studied. The purpose of this study was to analyze the Adult to Adult Living Donor Liver Transplantation Study (A2ALL) data to report outcomes of re-LT after LDLT, with a focus on long-term survival after re-LT. METHODS: A retrospective review of A2ALL data collected between 1998 and 2014 was performed. Patients were excluded if they received a deceased donor LT. Demographic data, postoperative outcomes and complications, graft and patient survival, and predictors of re-LT and patient survival were assessed. RESULTS: Of the 1065 patients who underwent LDLT during the study time period, 110 recipients (10.3%) required re-LT. In multivariable analyses, hepatitis C virus, longer length of stay at LDLT, hepatic artery thrombosis, biliary stricture, infection, and disease recurrence were associated with an increased risk of re-LT. Patient survival among re-LT patients was significantly inferior to those who underwent primary transplant only at 1 (86% versus 92%), 5 (64% versus 82%), and 10 years (44% versus 68%). CONCLUSIONS: Approximately 10% of A2ALL patients who underwent primary LDLT required re-LT. Compared with patients who underwent primary LT, survival among re-LT recipients was worse at 1, 5, and 10 years after LT, and re-LT was associated with a significantly increased risk of death in multivariable modeling (hazard ratios, 2.29; P < 0.001).
