To provide an update on the recent publications for the management and prognostication of critically ill cirrhotic patients before and after liver transplant.
The CLIF Acute-oN-ChrONicLIver Failure in Cirrhosis (CANONIC) study recently derived an evidence-based definition of acute-on-chronic liver failure (ACLF): hepatic decompensation; organ failure [predefined by the Chronic Liver Failure-Sequential Organ Failure Assessment (CLIF-SOFA)]; and high 28-day mortality rate. Although Sequential Organ Failure Assessment (SOFA) appears to be more accurate in predicting ICU and hospital mortality in ACLF patients, CLIF-SOFA has been derived specifically for critically ill cirrhotic patients, including those not receiving mechanical ventilation. Recent data suggest that a lower transfusion target in esophageal variceal bleeding (<7 g/l) is safe. Newly defined 'cirrhosis-associated acute kidney injury (AKI)' correlates with mortality, organ failure and length of hospital stay. Although the SOFA score appears to perform better than liver-specific scoring systems [Model for End-stage Liver Disease (MELD) and Child-Pugh scores], neither MELD nor SOFA appears to independently predict posttransplant survival; however, correlated with lengths of ICU and hospital stay. For patients declined for liver transplant, palliative care referral and appropriate goals of care are rarely achieved.
New definitions for ACLF, cirrhosis-associated AKI and the CLIF-SOFA may improve the discrimination between survivors and nonsurvivors with ACLF. Predicting futility postliver transplant based on preliver transplant severity of illness still poses significant challenges.
提供有关肝移植前后重症肝硬化患者管理与预后的近期出版物的最新信息。
肝硬化慢性-急性肝衰竭(CANONIC)研究最近得出了基于证据的急性-慢性肝衰竭(ACLF)定义:肝失代偿;器官衰竭[由慢性肝衰竭-序贯器官衰竭评估(CLIF-SOFA)预先定义];以及28天高死亡率。尽管序贯器官衰竭评估(SOFA)在预测ACLF患者的ICU和医院死亡率方面似乎更准确,但CLIF-SOFA是专门为重症肝硬化患者推导出来的,包括那些未接受机械通气的患者。最近的数据表明,食管静脉曲张出血时较低的输血目标(<7g/l)是安全的。新定义的“肝硬化相关性急性肾损伤(AKI)”与死亡率、器官衰竭和住院时间相关。尽管SOFA评分似乎比肝脏特异性评分系统[终末期肝病模型(MELD)和Child-Pugh评分]表现更好,但MELD和SOFA似乎都不能独立预测移植后生存率;然而,它们与ICU和医院住院时间相关。对于被拒绝肝移植的患者,姑息治疗转诊和适当的护理目标很少能实现。
ACLF、肝硬化相关性AKI和CLIF-SOFA的新定义可能会改善ACLF患者中幸存者与非幸存者之间的区分。基于肝移植前疾病严重程度预测肝移植后的无效性仍然面临重大挑战。
