Abstract
AIMS: Recent data have demonstrated greater than 80% one-year survival probability after liver transplantation (LT) for patients with severe acute on chronic liver failure (ACLF). However, long term outcomes and complications are still unknown for this population. Our aim was to compare long-term patient and graft survival among patients transplanted across all grades of ACLF. METHODS: We analyzed the UNOS database, years 2004-2017. Patients with ACLF were identified using the EASL-CLIF criteria. Kaplan-Meier and Cox regression methods were used to determine patient and graft survival and associated predictors of mortality in adjusted models. RESULTS: A total of 75,844 patients were transplanted of which 48,854 (64.4%) had no ACLF, 9,337 (12.3%) had ACLF-1, 9,386 (12.4%) had ACLF-2 and 8,267 (10.9%) had ACLF-3. Patients transplanted without ACLF had a greater proportion of hepatocellular carcinoma within (23.8%) and outside (12.7%) Milan criteria. Five-year patient survival after LT was lower in the ACLF-3 patients compared with the other groups (67.7%, p<0.001), although after year 1, the percentage decrease in survival was similar among all groups. Infection was the primary cause of death among all patient groups in the first year. After the first year, infection was the main cause of death in patients transplanted with ACLF-1 (31.1%), ACLF-2 (33.3%) and ACLF-3 (36.7%), whereas malignancy was the predominant cause of death in those transplanted with no ACLF (38.5%). Graft survival probability at 5 years was above 90% among all patient groups. CONCLUSION: Patients transplanted with ACLF-3 have lower 5-year survival as compared to ACLF 0-2 but mortality rates were not significantly different after the first year following LT. Graft survival was excellent across all ACLF groups.
