OBJECTIVES: We aimed to evaluate the effect of acute-on-chronic liver failure (ACLF) on patients' 1-year post-liver transplant (LT) survival. In addition, we evaluated the effect of ACLF on the development of post-LT chronic kidney disease (CKD) and early allograft dysfunction (EAD). PATIENTS AND METHODS: A retrospective cohort of patients who underwent transplantation from 2010 to 2016 was studied. EASL-CLIF's definition of ACLF was used. The risk of post-LT death, CKD, and EAD was estimated with regression models weighted by inverse probability weighting considering the recipients' characteristics. Donor's BMI and donor risk index were included in the models as well. RESULTS: A total of 185 patients were included: 125 (67.6%) without ACLF and 60 (32.4%) with ACLF. The 1-year post-LT survival rate was 91.2% [95% confidence interval (CI): 84.6-95.1%] in patients without ACLF versus 84.9% (95% CI: 73.1-91.9%) in patients with ACLF. Post-LT CKD occurred in 43 (38.7%) patients without ACLF versus 26 (52.0%) patients with ACLF. EAD occurred in 40 (32.3%) patients without ACLF versus 15 (28.8%) patients with ACLF. No effect of ACLF was found on survival (hazard ratio 1.75; 95% CI: 0.64-4.75, P = 0.272), CKD (odds ratio: 1.31; 95% CI: 0.60-2.86; P = 0.491), or EAD (odds ratio: 0.74; 95% CI: 0.38-1.66, P = 0.473). CONCLUSION: In this study, which included mainly patients with grade 1 ACLF at the time of LT, its presence had no impact on post-LT survival or on the occurrence of CKD or EAD.
