CLIF-SOFA and CLIF-C scores for the prognostication of acute-on-chronic liver failure and acute decompensation of cirrhosis: A systematic review

Abstract

BACKGROUND Acute-on-chronic liver failure (ACLF) is a syndrome characterized by decompensation in individuals with chronic liver disease, generally secondary to one or more extra-hepatic organ failures, implying an elevated mortality rate. Acute decompensation (AD) is the term used for one or more significant consequences of liver disease in a short time and is the most common reason for hospital admission in cirrhotic patients. The European Association for the Study of Liver-Chronic-Liver Failure (EASL-CLIF) Group modified the intensive care Sequential Organ Failure Assessment score into CLIF-SOFA, which detects the presence of ACLF in patients with or without AD, classifying it into three grades . AIM To investigate the role of the EASL-CLIF definition for ACLF and the ability of CLIF-SOFA, CLIF-C ACLF, and CLIF-C AD scores for prognosticating ACLF or AD. METHODS This study is a literature review using a standardized search method, conducted using the steps following the guidelines for reporting systematic reviews set out by the PRISMA statement. For specific keywords, relevant articles were found by searching PubMed, ScienceDirect, and BioMed Central-BMC. The databases were searched using the search terms by one reviewer, and a list of potentially eligible studies was generated based on the titles and abstracts screened. The data were then extracted and assessed on the basis of the Reference Citation Analysis ( ). RESULTS Most of the included studies used the EASL-CLIF definition for ACLF to identify cirrhotic patients with a significant risk of short-term mortality. The primary outcome in all reviewed studies was mortality. Most of the study findings were based on an area under the receiver operating characteristic curve (AUROC) analysis, which revealed that CLIF-SOFA, CLIF-C ACLF, and CLIF-C AD scores were preferable to other models predicting 28-d mortality. Their AUROC scores were higher and able to predict all-cause mortality at 90, 180, and 365 d. A total of 50 articles were included in this study, which found that the CLIF-SOFA, CLIF-C ACLF and CLIF-C AD scores in more than half of the articles were able to predict short-term and long-term mortality in patients with either ACLF or AD. CONCLUSION CLIF-SOFA score surpasses other models in predicting mortality in ACLF patients, especially in the short-term. CLIF-SOFA, CLIF-C ACLF, and CLIF-C AD are accurate short-term and long-term mortality prognosticating scores.

Acute-on-chronic liver failure is independently associated with higher mortality for cirrhotic patients with acute esophageal variceal hemorrhage: Retrospective cohort study

“…This has been demonstrated in a few previous retrospective cohorts[ 73 , 77 - 81 ]. A recent systematic review investigated the ability of the CLIF-SOFA, CLIF-C ACLF, and CLIF-C AD scores for prognosticating acute-on-chronic liver failure and acute decompensation of cirrhosis and it was found that these scores are accurate as short-term and long-term mortality prognosticating scores, with CLIF-SOFA being the most effective in predicting mortality in ACLF patients, especially in the short-term[ 82 ].…”

Early Prediction of Acute-on-Chronic Liver Failure Development in patients with diverse chronic liver diseases

“…All these scores have good performance in ACLF prognosis assessment and disease severity, but the effect of early warning and accurate assessment of ACLF for patients with various acute and chronic liver diseases was unsatisfactory. [8][9][10][11][12] In a retrospective study of 75,922 patients with compensatory cirrhosis, Karen Y. et al 13 used multivariate logistic regression to develop predictive models (called voice-Penn) for the occurrence of ACLF at 3, 6, and 12 months. They found that albumin(ALB), international normalized ratio(INR), total bilirubin(TBiL), and creatinine(Cr) were signi cant predictors at each time point.…”
