Characteristics and predictors of short-term mortality in decompensated cirrhotic patients with acute-on-chronic liver failure.

ABSTRACT:

Aim of the study

We aimed to investigate the characteristics of acute-on-chronic liver failure (ACLF) and factors associated with 28-day mortality in patients with ACLF.

Material and methods

This prospective study included ACLF patients based on the European Association for the Study of the Liver-Chronic Liver Failure (EASL-CLIF) Consortium criteria, admitted between March 2021 and February 2022. We examined variables associated with 28-day mortality using multivariate Cox regression analysis.

Results

Of 326 patients admitted with acute decompensation (AD) of cirrhosis, 109 (33.44%) patients were diagnosed with ACLF (mean age 63.61 ±11.15 years, 65.14% males). Of these, 26.61%, 35.78%, and 37.61% of patients were in ACLF grades 1, 2, and 3 respectively. HCV (80.73%) was the main aetiology of cirrhosis. Upper gastrointestinal bleeding (25.69%) was the most common trigger. Kidney failure (73.39%) was the most common organ failure. The 28-day mortality rate was 66.97%. Cox regression analysis revealed that the existence of 2 (HR = 6.99, 95% CI: 2.68-18.25, p < 0.0001) or ≥ 3 (HR = 9.34, 95% CI: 3.6-24.74, p < 0.0001) organ failures, hepatic encephalopathy (HR = 2.96, 95% CI: 1.27-6.94, p = 0.01), and elevated serum bilirubin (HR = 1.03, 95% CI: 1.00-1.06, p = 0.04) were independent predictors for 28-day mortality, while shifting blood pH to the normal range was associated with a decrease in the HR of ACLF mortality (HR = 0.03, 95% CI: 0.002-0.44, p = 0.01).

Conclusions

ACLF has a very high 28-day mortality, which is associated with the existence of 2 or more organ failures, hepatic encephalopathy, elevated serum bilirubin, and low blood pH.

Project description:To validate prognostic scores for acute decompensation of cirrhosis and acute-on-chronic liver failure in Brazilian patients.This is a prospective cohort study designed to assess the prognostic performance of the chronic liver failure-consortium (CLIF-C) acute decompensation score (CLIF-C AD) and CLIF-C acute-on-chronic liver failure score (CLIF-C ACLF), regarding 28-d and 90-d mortality, as well as to compare them to other prognostic models, such as Model for End-Stage Liver Disease (MELD), MELD Sodium (MELD-Na), Child-Pugh (CP) score, and the CLIF-C Organ Failure score (CLIF-C OF). All participants were adults with acute decompensation of cirrhosis admitted to the Emergency Department of a tertiary hospital in southern Brazil. Prognostic performances were evaluated by means of the receiver operating characteristic (ROC) curves, area under the curves (AUC) and 95%CI.One hundred and thirteen cirrhotic patients were included. At admission, 18 patients had acute-on-chronic liver failure (ACLF) and 95 individuals had acute decompensation (AD) without ACLF, of which 24 eventually developed ACLF during the course of hospitalization (AD evolving to ACLF group). The AD group had significantly lower 28-d (9.0%) and 90-d (18.3%) mortality as compared to the AD evolving to ACLF group and to the ACLF group (both P < 0.001). On the other hand, 28-d and 90-d mortalities were not significantly different between AD evolving to ACLF group and ACLF group (P = 0.542 and P = 0.708, respectively). Among patients with ACLF, at 28 d from the diagnosis, CLIF-C ACLF was the only score able to predict mortality significantly better than the reference line, with an AUC (95%CI) of 0.71 (95%CI: 0.54-0.88, P = 0.021). Among patients with AD, all prognostic scores performed significantly better than the reference line regarding 28-d mortality, presenting with similar AUCs: CLIF-C AD score 0.75 (95%CI: 0.63-0.88), CP score 0.72 (95%CI: 0.59-0.85), MELD score 0.75 (95%CI: 0.61-0.90), MELD-Na score 0.76 (95%CI: 0.61-0.90), and CLIF-C OF score 0.74 (95%CI: 0.60-0.88). The same occurred concerning AUCs for 90-d mortality: CLIF-C AD score 0.70 (95%CI: 0.57-0.82), CP score 0.73 (95%CI: 0.62-0.84), MELD score 0.71 (95%CI: 0.59-0.83), MELD-Na score 0.73 (95%CI: 0.62-0.84), and CLIF-C OF score 0.65 (95%CI: 0.52-0.78).This study demonstrated that CLIF-C ACLF is the best available score for the prediction of 28-d mortality among patients with ACLF. CLIF-C AD score is also useful for the prediction of mortality among cirrhotic patients with AD not fulfilling diagnostic criteria for ACLF, but it was not superior to other well-established prognostic scores.

Project description:Background & aimsBody composition is sex dependent and associated with an increased mortality risk in patients with cirrhosis. We evaluated whether it was also associated with short-term mortality in patients critically ill with acute-on-chronic liver failure (ACLF).Patients and methodsWe retrospectively included all patients with cirrhosis and ACLF hospitalised in the intensive care unit (ICU) of Lausanne University Hospital between 2010 and 2019 for whom an abdominal computed tomography (CT) scan performed ±7 days from admission was available. Patients from the ICU of Paul Brousse University Hospital admitted between 2017 and 2020 served as an external cohort. All body composition parameters at the third lumbar vertebral level (L3) were quantified using a deep learning-based method.ResultsIn total, 192 patients from Lausanne were included. Median age was 62 years and 28-day survival rate was 58.2%. In males, variables independently associated with 28-day mortality on days 1 and 3 were Chronic Liver Failure Consortium (CLIF-C) ACLF-lactate and sarcopenia. In females, CLIF-C ACLF-lactate on days 1 and 3 was the only predictor of 28-day survival. We derived two scores combining sarcopenia and the CLIF-C ACLF-lactate score on days 1 and 3, with area under the receiver operating characteristic outperforming the CLIF-C ACLF-lactate score alone in male but not in female patients. Comparable results were found in the external cohort of 58 patients and supported the sex specificity of the performance of the model. Patients with sarcopenia had increased risks of invasive fungal infection and renal replacement therapy.ConclusionSarcopenia was associated with 28-day mortality in male but not in female patients critically ill with ACLF. Although screening for sarcopenia could impact the management of male patients, further studies are needed in female cohorts to investigate whether other body composition parameters are associated with outcomes.Impact and implicationsBody composition, easily assessed by CT, is altered in patients with cirrhosis and associated with outcome; it has never been investigated in patients critically ill with ACLF. The results of the present study, underlining the benefit of sarcopenia evaluation to improve prognosis prediction in males critically ill with ACLF, are of importance for physicians managing such patients to optimise the decision-making process toward continued treatment, liver transplantation, or limitation of care. In a wider sense, besides the number and course of organ failures, the results recall the weight of the general condition of males with ACLF at admission to ICU. In females critically ill with ACLF, in analyses limited by the sample size, none of the body composition parameters was associated with short-term mortality independently of organ failures; this suggests that the number and course of organ failures are the main determinant of mortality in these patients.

Project description:Background & aimsAcute-on-chronic liver failure (ACLF) carries a high short-term mortality for patients with cirrhosis. Prior literature suggests that statin exposure may reduce the likelihood of ACLF events. However, it is unclear if statin exposure is associated with ACLF-related mortality. This study sought to determine the association between statin use and short-term mortality among patients hospitalised with ACLF.MethodsThis was a retrospective cohort study of Veterans Health Administration (VHA) patients diagnosed with cirrhosis between 2008 and 2021 and hospitalised with high-grade (2 or 3) ACLF. Patients were stratified into those with and without continuous statin exposure for at least 90 days prior to hospitalisation. Multivariable logistic regression models were created to determine the adjusted association between statin exposure and 28-day and 90-day mortality. Categorical statin dose exposure, converted to simvastatin equivalents, was also explored.ResultsA total of 11,731 patients with cirrhosis hospitalised with Grade 2 or 3 ACLF were included in the analytic cohort, 26% of whom had statin exposure. In adjusted logistic regression models, statin use was associated with 18% lower odds of ACLF-related 28-day mortality (odds ratio [OR] 0.82, 95% CI 0.73-0.93, p = 0.001) and 24% lower odds of 90-day mortality (OR 0.76, 95% CI 0.68-0.86, p <0.001). Increasing statin dose exposure was also associated with further reductions in 90-day mortality (e.g. OR 0.81, 95% CI 0.70-0.93 for 10-40 mg vs. 0 mg and OR 0.72, 95% CI 0.60-0.87 for 80 mg vs. 0 mg, p <0.001).ConclusionsIn this large, retrospective cohort study, statin exposure before high-grade ACLF hospitalisation was associated with reduced odds of 28-day and 90-day mortality in patients with cirrhosis. A statin dose-dependent reduction in 90-day ACLF-related mortality was also observed.Impact and implicationsStatins have been identified as a class of medications with potential beneficial effects for patients with cirrhosis. In this large, retrospective cohort study of patients with cirrhosis who seek care at the Veterans Health Administration, statin use was associated with a decrease in short term (28-day and 90-day) mortality as a result of acute-on-chronic liver failure. Future prospective studies are needed to further clarify the relative safety and efficacy of statin therapy in reducing morbidity and mortality associated with acute-on-chronic liver failure in patients with cirrhosis.

Project description:BackgroundAcute-on-chronic liver failure (ACLF) is a life-threatening hepatic syndrome. Therefore, this study aimed to develop a comprehensive model combining extracellular liver volume derived from spectral CT (ECVIC-liver) and sarcopenia, for the early prediction of short-term (90-day) disease progression in ACLF.Materials and methodsA retrospective cohort of 126 ACLF patients who underwent hepatic spectral CT scans was included. According to the Asia-Pacific Association for the Study of the Liver (APASL) criteria, patients were divided into the progression group (n = 70) and the stable group (n = 56). ECVIC-liver was measured on the equilibrium period (EP) images of spectral CT, and L3-SMI was measured on unenhanced CT images, with sarcopenia assessed. A comprehensive model was developed by combining independent predictors. Model performance was evaluated using receiver operating characteristic (ROC) curve analysis, calibration curves, and decision curve analysis (DCA).ResultsIn the univariate analysis, BMI, WBC, PLT, PTA, L3-SMI, IC-EP, Z-EP, K140-EP, NIC-EP, ECVIC-liver, and Sarcopenia demonstrated associations with disease progression status at 90 days in ACLF patients. In multivariate logistic regression, white blood cell count (WBC) (OR = 1.19, 95% CI: 1.02-1.40; P = 0.026), ECVIC-liver (OR = 1.27, 95% CI: 1.15-1.40; P < 0.001), sarcopenia (OR = 4.15, 95% CI: 1.43-12.01; P = 0.009), MELD-Na score (OR = 1.06, 95%CI: 1.01-1.13;P = 0.042), and CLIF-SOFA score (OR = 1.37, 95%CI:1.15-1.64; P<0.001) emerged as independent risk factors for ACLF progression. The combined model exhibited superior predictive performance (AUCs = 0.910, sensitivity = 80.4%, specificity = 90.0%, PPV = 0.865, NPV = 0.851) compared to CLIF-SOFA, MELD-Na, MELD and CTP scores(both P < 0.001). Calibration curves and DCA confirmed the high clinical utility of the combined model.ConclusionsPatients without sarcopenia and/or with a lower ECVIC-liver have a better prognosis, and the integration of WBC, ECVIC-liver, Sarcopenia, CLIF-SOFA and MELD-Na scores in a composite model offers a concise and effective tool for predicting disease progression in ACLF patients.Trial registrationNot Applicable.
