摘要：The albumin–bilirubin (ALBI) score is calculated using only serum albumin and bilirubin levels, and was developed as a simple method to assess hepatic function. In this study, a total of 409 patients with primary biliary cholangitis (PBC) were enrolled between March 1990 and October 2018. The predictive performances of the ALBI score and other well-established prognostic scores were compared using time-dependent receiver operating characteristic (ROC) analysis. During the follow-up period, 60 patients died, 45 due to liver-related diseases and 15 due to non-liver-related diseases, and 16 patients underwent liver transplantation. Time-dependent ROC analysis showed that the ALBI score has higher the areas under the ROC curves (AUROCs) than the Child–Pugh (C–P) score at each time point; AUROCs at 3, 5, and 10 years after the start of follow-up were 0.94, 0.91, and 0.90 for the ALBI score, and 0.89, 0.88, and 0.82 for the C–P score, respectively. The ALBI score showed the highest AUROCs within 2 years after the start of observation; beyond 2 years, however, the Mayo score had better prognostic ability for mortality and liver transplantation. The ALBI score/grade, derived from objective blood tests, and the Mayo score were superior prognostic tools in PBC patients.
