Background & Aims: Acute decompensation (AD) of cirrhosis may present without acute-on-chronic liver failure (ACLF) (AD-No ACLF), or with ACLF (AD-ACLF), defined by organ failure(s). Herein, we aimed to analyze and characterize the precipitants leading to both of these AD phenotypes., Methods: The multicenter, prospective, observational PREDICT study (NCT03056612) included 1,273 non-electively hospitalized patients with AD (No ACLF = 1,071; ACLF = 202). Medical history, clinical data and laboratory data were collected at enrolment and during 90-day follow-up, with particular attention given to the following characteristics of precipitants: induction of organ dysfunction or failure, systemic inflammation, chronology, intensity, and relationship to outcome., Results: Among various clinical events, 4 distinct events were precipitants consistently related to AD: proven bacterial infections, severe alcoholic hepatitis, gastrointestinal bleeding with shock and toxic encephalopathy. Among patients with precipitants in the AD-No ACLF cohort and the AD-ACLF cohort (38% and 71%, respectively), almost all (96% and 97%, respectively) showed proven bacterial infection and severe alcoholic hepatitis, either alone or in combination with other events. Survival was similar in patients with proven bacterial infections or severe alcoholic hepatitis in both AD phenotypes. The number of precipitants was associated with significantly increased 90-day mortality and was paralleled by increasing levels of surrogates for systemic inflammation. Importantly, adequate first-line antibiotic treatment of proven bacterial infections was associated with a lower ACLF development rate and lower 90-day mortality., Conclusions: This study identified precipitants that are significantly associated with a distinct clinical course and prognosis in patients with AD. Specific preventive and therapeutic strategies targeting these events may improve outcomes in patients with decompensated cirrhosis., Lay Summary: Acute decompensation (AD) of cirrhosis is characterized by a rapid deterioration in patient health. Herein, we aimed to analyze the precipitating events that cause AD in patients with cirrhosis. Proven bacterial infections and severe alcoholic hepatitis, either alone or in combination, accounted for almost all (96-97%) cases of AD and acute-on-chronic liver failure. Whilst the type of precipitant was not associated with mortality, the number of precipitant(s) was. This study identified precipitants that are significantly associated with a distinct clinical course and prognosis of patients with AD. Specific preventive and therapeutic strategies targeting these events may improve patient outcomes., Competing Interests: Conflict of interest None of the authors have conflicts of interest for the reported study.

Background & Aims: Acute decompensation (AD) of cirrhosis is defined as the acute development of ascites, gastrointestinal hemorrhage, hepatic encephalopathy, infection or any combination thereof, requiring hospitalization. The presence of organ failure(s) in patients with AD defines acute-on-chronic liver failure (ACLF). The PREDICT study is a European, prospective, observational study, designed to characterize the clinical course of AD and to identify predictors of ACLF., Methods: A total of 1,071 patients with AD were enrolled. We collected detailed pre-specified information on the 3-month period prior to enrollment, and clinical and laboratory data at enrollment. Patients were then closely followed up for 3 months. Outcomes (liver transplantation and death) at 1 year were also recorded., Results: Three groups of patients were identified. Pre-ACLF patients (n = 218) developed ACLF and had 3-month and 1-year mortality rates of 53.7% and 67.4%, respectively. Unstable decompensated cirrhosis (UDC) patients (n = 233) required ≥1 readmission but did not develop ACLF and had mortality rates of 21.0% and 35.6%, respectively. Stable decompensated cirrhosis (SDC) patients (n = 620) were not readmitted, did not develop ACLF and had a 1-year mortality rate of only 9.5%. The 3 groups differed significantly regarding the grade and course of systemic inflammation (high-grade at enrollment with aggravation during follow-up in pre-ACLF; low-grade at enrollment with subsequent steady-course in UDC; and low-grade at enrollment with subsequent improvement in SDC) and the prevalence of surrogates of severe portal hypertension throughout the study (high in UDC vs. low in pre-ACLF and SDC)., Conclusions: Acute decompensation without ACLF is a heterogeneous condition with 3 different clinical courses and 2 major pathophysiological mechanisms: systemic inflammation and portal hypertension. Predicting the development of ACLF remains a major future challenge. CLINICALTRIALS., Gov Number: NCT03056612., Lay Summary: Herein, we describe, for the first time, 3 different clinical courses of acute decompensation (AD) of cirrhosis after hospital admission. The first clinical course includes patients who develop acute-on-chronic liver failure (ACLF) and have a high short-term risk of death - termed pre-ACLF. The second clinical course (unstable decompensated cirrhosis) includes patients requiring frequent hospitalizations unrelated to ACLF and is associated with a lower mortality risk than pre-ACLF. Finally, the third clinical course (stable decompensated cirrhosis), includes two-thirds of all patients admitted to hospital with AD - patients in this group rarely require hospital admission and have a much lower 1-year mortality risk., Competing Interests: Conflict of interest None of the authors have conflicts of interest for the reported study.

The incidence of chronic liver disease has increased in Europe and can lead to Acute on Chronic Liver Failure (ACLF) which is associated with high levels of mortality due to multisystem organ failure. The characteristics of the ACLF patients can change very rapidly within a short period of time. Continuous assessment of their recovery status is critical for clinicians to adjust and deliver effective treatment. The aim of this paper is to validate the usefulness of a data preparation approach by combining different criteria to replace missing values, balance target-class variables, select useful patient characteristics and optimise hyperparameters of machine learning models for the prediction of ACLF associated mortality rates. A key step in the data preparation is a feature selection Mutual Information (MI) based multivariate approach to build smaller, and yet equally and in some cases more informative, subsets of patient characteristics than those frequently proposed for the prediction of mortality, from patients with ACLF in the CANONIC dataset. The usefulness of the data preparation approach proposed to predict mortality was evaluated by training the XGBoost and Logistic Regression models with the prepared data. Evaluations of the models trained using a test set provided evidence of an overall high accuracy in the prediction of the mortality rates of patients for days after their diagnosis, and in some cases even higher when reduced and more informative subsets of patient characteristics were found.

Systemic inflammation (SI) is involved in the pathogenesis of acute decompensation (AD) and acute-on-chronic liver failure (ACLF) in cirrhosis. In other diseases, SI activates tryptophan (Trp) degradation through the kynurenine pathway (KP), giving rise to metabolites that contribute to multiorgan/system damage and immunosuppression. In the current study, we aimed to characterize the KP in patients with cirrhosis, in whom this pathway is poorly known. The serum levels of Trp, key KP metabolites (kynurenine and kynurenic and quinolinic acids), and cytokines (SI markers) were measured at enrollment in 40 healthy subjects, 39 patients with compensated cirrhosis, 342 with AD (no ACLF) and 180 with ACLF, and repeated in 258 patients during the 28-day follow-up. Urine KP metabolites were measured in 50 patients with ACLF. Serum KP activity was normal in compensated cirrhosis, increased in AD and further increased in ACLF, in parallel with SI; it was remarkably higher in ACLF with kidney failure than in ACLF without kidney failure in the absence of differences in urine KP activity and fractional excretion of KP metabolites. The short-term course of AD and ACLF (worsening, improvement, stable) correlated closely with follow-up changes in serum KP activity. Among patients with AD at enrollment, those with the highest baseline KP activity developed ACLF during follow-up. Among patients who had ACLF at enrollment, those with immune suppression and the highest KP activity, both at baseline, developed nosocomial infections during follow-up. Finally, higher baseline KP activity independently predicted mortality in patients with AD and ACLF. Conclusion: Features of KP activation appear in patients with AD, culminate in patients with ACLF, and may be involved in the pathogenesis of ACLF, clinical course, and mortality., (© 2018 by the American Association for the Study of Liver Diseases.)

Background & Aims: Antibiotic resistance has been increasingly reported in patients with decompensated cirrhosis in single-center studies. Prospective investigations reporting broad epidemiological data are scarce. We aimed to analyze epidemiological changes in bacterial infections in patients with decompensated cirrhosis., Methods: This was a prospective evaluation of 2 series of patients hospitalized with decompensated cirrhosis. The Canonic series included 1,146 patients from Northern, Southern and Western Europe in 2011. Data on epidemiology, clinical characteristics of bacterial infections, microbiology and empirical antibiotic schedules were assessed. A second series of 883 patients from Eastern, Southern and Western Europe was investigated between 2017-2018., Results: A total of 455 patients developed 520 infections (39.7%) in the first series, with spontaneous bacterial peritonitis, urinary tract infections and pneumonia the most frequent infections. Nosocomial episodes predominated in this series. Nearly half of the infections were culture-positive, of which 29.2% were caused by multidrug-resistant organisms (MDROs). MDR strains were more frequently isolated in Northern and Western Europe. Extended-spectrum beta-lactamase-producing Enterobacteriaceae were the most frequent MDROs isolated in this series, although prevalence and type differed markedly among countries and centers. Antibiotic resistance was associated with poor prognosis and failure of antibiotic strategies, based on third-generation cephalosporins or quinolones. Nosocomial infection (odds ratio [OR] 2.74; p < 0.001), intensive care unit admission (OR 2.09; p = 0.02), and recent hospitalization (OR 1.93; p = 0.04) were identified as independent predictors of MDR infection. The prevalence of MDROs in the second series (392 infections/284 patients) was 23%; 38% in culture-positive infections. A mild increase in the rate of carbapenem-resistant Enterobacteriaceae was observed in this series., Conclusions: MDR bacterial infections constitute a prevalent, growing and complex healthcare problem in patients with decompensated cirrhosis and acute-on-chronic liver failure across Europe, negatively impacting on prognosis. Strategies aimed at preventing the spread of antibiotic resistance in cirrhosis should be urgently evaluated., Lay Summary: Infections caused by bacteria resistant to the main antibiotic families are prevalent in patients with cirrhosis. This study demonstrates that this healthcare problem is increasing and extends through all European regions. Infections caused by these difficult to treat bacteria resolve less frequently and often cause the death of the patient. The type of resistant bacteria varies markedly among different hospitals., (Copyright © 2018 European Association for the Study of the Liver. Published by Elsevier B.V. All rights reserved.)

Objectives: To evaluate the Chronic Liver Failure-Consortium Acute on Chronic Liver Failure score in acute on chronic liver failure patients admitted to ICUs from different global regions and compare discrimination ability with previously published scores., Design: Retrospective pooled analysis., Setting: Academic ICUs in Canada (Edmonton, Vancouver) and Europe (Paris, Barcelona, Chronic liver failure/Acute-on-Chronic Liver Failure in Cirrhosis [CANONIC] study)., Patients: Sample of analysis of 867 cirrhotic patients with acute on chronic liver failure admitted to ICU. Cumulative incidence functions of death were estimated by acute on chronic liver failure grade at admission and at day 3. Survival discrimination abilities of Chronic Liver Failure-Consortium Acute on Chronic Liver Failure, Model for End-Stage Liver Disease, Acute Physiology and Chronic Health Evaluation II, and Child-Turcotte-Pugh scores were compared., Interventions: ICU admission for organ support., Measurements and Main Results: At admission 169 subjects (19%) had acute on chronic liver failure 1, 302 (35%) acute on chronic liver failure 2, and 396 (46%) had acute on chronic liver failure 3 with 90-mortality rates of 33%, 40%, and 74%, respectively (p < 0.001). At admission, Chronic Liver Failure-Consortium Acute on Chronic Liver Failure demonstrated superior discrimination at 90 days compared with Acute Physiology and Chronic Health Evaluation II (n = 532; concordance index 0.67 vs 0.62; p = 0.0027) and Child-Turcotte-Pugh (n = 666; 0.68 vs 0.64; p = 0.0035), but not Model for End-Stage Liver Disease (n = 845; 0.68 vs 0.67; p = 0.3). A Chronic Liver Failure-Consortium Acute on Chronic Liver Failure score greater than 70 at admission or on day 3 was associated with 90-day mortality rates of approximately 90%. Ninety-day mortality in grade 3 acute on chronic liver failure patients at admission who demonstrated improvement by day 3 was 40% (vs 79% in patients who did not)., Conclusions: The Chronic Liver Failure-Consortium Acute on Chronic Liver Failure demonstrated better discrimination at day 28 and day 90 compared with Acute Physiology and Chronic Health Evaluation II and Child-Turcotte-Pugh. Patients who demonstrated clinical improvement post-ICU admission (e.g., acute on chronic liver failure 3 to 1 or 2) at day 3 had better outcomes than those who did not. In high-risk ICU patients (Chronic Liver Failure-Consortium Acute on Chronic Liver Failure > 70), decisions regarding transition to palliation should be explored between patient families and the ICU providers after a short trial of therapy.

Background & Aims: Type 1 hepatorenal syndrome (HRS) is the most high-risk type of renal failure in patients with cirrhosis. Terlipressin and albumin are effective treatments for type 1 HRS. However, the effects of acute on chronic liver failure (ACLF) grade on response to treatment are not clear. We aimed to identify factors associated with response to treatment with terlipressin and albumin in patients with type 1 HRS (reduction in serum level of creatinine to below 1.5 mg/dL at the end of treatment) and factors associated with death within 90 days of HRS diagnosis (90-day mortality)., Methods: We performed a retrospective analysis of 4 different cohorts of consecutive patients with HRS treated with terlipressin and albumin from February 2007 through January 2016 at medical centers in Europe (total, 298 patients). We analyzed demographic, clinical, and laboratory data collected before and during treatment; patients were followed until death, liver transplantation, or 90 days after HRS diagnosis., Results: Response to treatment was observed in 53% of patients. Of patients with grade 1 ACLF, 60% responded to treatment; among those with grade 2 ACLF, 48% responded, and among those with grade 3 ACLF, 29% responded (P < .001 for comparison between grades). In multivariate analysis, baseline serum level of creatinine (odds ratio, 0.23; P = .001) and ACLF grade (odds ratio, 0.63; P = .01) were independently associated with response to treatment. Patient age (hazard ratio [HR], 1.05; P < .001), white blood cell count (HR, 1.51; P = .006), ACLF grade (HR, 2.06; P < .001), and no response to treatment (HR, 0.41; P < .001) associated with 90-day mortality., Conclusion: In a retrospective analysis of data from 4 cohorts of patients treated for type 1 HRS, we found ACLF grade to be the largest determinant of response to terlipressin and albumin. ACLF grade affects survival independently of response to treatment. New therapeutic strategies should be developed for patients with type 1 HRS and extrarenal organ failure., (Copyright © 2018 AGA Institute. Published by Elsevier Inc. All rights reserved.)

Acute on chronic liver failure (ACLF) is the culmination of chronic liver disease and extrahepatic organ failures, which is associated with a high short-term mortality and immense health care expenditure. There are varying definitions for organ failures and ACLF in Europe, North America, and Asia. These differing definitions need to be reconciled to enhance progress in the field. The pathogenesis of ACLF is multifactorial and related to interactions between the immunoinflammatory system, microbiota, and the various precipitating factors. Individual organ failures related to the kidney, brain, lungs, and circulation have cumulative adverse effects on mortality and are often complicated or precipitated by infections. Strategies to prevent and rapidly treat these organ failures are paramount in improving survival. With the aging population and paucity of organs for liver transplant, the prognosis of ACLF patients is poor, highlighting the need for novel therapeutic strategies. The role of liver transplant in ACLF is evolving and needs further investigation across large consortia. A role for early palliative care and management of frailty as approaches to alleviate disease burden and improve patient-reported outcomes is being increasingly recognized., Conclusion: ACLF is a clinically relevant syndrome that is epidemic worldwide and requires a dedicated multinational approach focused on prognostication and management; investigations are underway worldwide to prepare ACLF for prime time.

Objective: Prognostic stratification of patients with cirrhosis is common clinical practice. This study compares the prognostic accuracy (28-day and 90-day transplant-free mortality) of the acute-on-chronic liver failure (ACLF) classification (no ACLF, ACLF grades 1, 2 and 3) with that of acute kidney injury (AKI) classification (no AKI, AKI stages 1, 2 and 3)., Design: The study was performed in 510 patients with an acute decompensation of cirrhosis previously included in the European Association for the Study of the Liver-Chronic Liver Failure consortium CANONIC study. ACLF was evaluated at enrollment and 48 h after enrollment, and AKI was evaluated at 48 h according to Acute Kidney Injury Network criteria., Results: 240 patients (47.1%) met the criteria of ACLF at enrollment, while 98 patients (19.2%) developed AKI. The presence of ACLF and AKI was strongly associated with mortality. 28-day transplant-free mortality and 90-day transplant-free mortality of patients with ACLF (32% and 49.8%, respectively) were significantly higher with respect to those of patients without ACLF (6.2% and 16.4%, respectively; both p<0.001). Corresponding values in patients with and without AKI were 46% and 59%, and 12% and 25.6%, respectively (p<0.0001 for both). ACLF classification was more accurate than AKI classification in predicting 90-day mortality (area under the receiving operating characteristic curve=0.72 vs 0.62; p<0.0001) in the whole series of patients. Moreover, assessment of ACLF classification at 48 h had significantly better prognostic accuracy compared with that of both AKI classification and ACLF classification at enrollment., Conclusions: ACLF stratification is more accurate than AKI stratification in the prediction of short-term mortality in patients with acute decompensation of cirrhosis., (Published by the BMJ Publishing Group Limited.

Unlabelled: Acute-on-chronic liver failure (ACLF) is characterized by acute decompensation (AD) of cirrhosis, organ failure(s), and high 28-day mortality. We investigated whether assessments of patients at specific time points predicted their need for liver transplantation (LT) or the potential futility of their care. We assessed clinical courses of 388 patients who had ACLF at enrollment, from February through September 2011, or during early (28-day) follow-up of the prospective multicenter European Chronic Liver Failure (CLIF) ACLF in Cirrhosis study. We assessed ACLF grades at different time points to define disease resolution, improvement, worsening, or steady or fluctuating course. ACLF resolved or improved in 49.2%, had a steady or fluctuating course in 30.4%, and worsened in 20.4%. The 28-day transplant-free mortality was low-to-moderate (6%-18%) in patients with nonsevere early course (final no ACLF or ACLF-1) and high-to-very high (42%-92%) in those with severe early course (final ACLF-2 or -3) independently of initial grades. Independent predictors of course severity were CLIF Consortium ACLF score (CLIF-C ACLFs) and presence of liver failure (total bilirubin ≥12 mg/dL) at ACLF diagnosis. Eighty-one percent had their final ACLF grade at 1 week, resulting in accurate prediction of short- (28-day) and mid-term (90-day) mortality by ACLF grade at 3-7 days. Among patients that underwent early LT, 75% survived for at least 1 year. Among patients with ≥4 organ failures, or CLIF-C ACLFs >64 at days 3-7 days, and did not undergo LT, mortality was 100% by 28 days., Conclusions: Assessment of ACLF patients at 3-7 days of the syndrome provides a tool to define the emergency of LT and a rational basis for intensive care discontinuation owing to futility., (© 2015 by the American Association for the Study of Liver Diseases.)

Patients hospitalized for an acute complication of cirrhosis who also have organ failure(s) are at high risk of short-term death. The term acute-on-chronic liver failure (ACLF) is used to characterize these patients. Until recently, there was no evidence-based definition of ACLF. The results of a large prospective observational European study called Chronic Liver Failure Consortium Acute-on-Chronic Liver Failure in Cirrhosis study were published in 2013 establishing diagnostic criteria for ACLF in a large series of hospitalized patients who had an acute complication of cirrhosis. In addition, this study described the natural history of ACLF. According to the Acute-on-Chronic Liver Failure in Cirrhosis study, ACLF is now considered a new clinical entity because it is distinct from traditional decompensated cirrhosis, based not only on the presence of organ failure(s) and high mortality rate but also on younger age, alcoholic etiology of cirrhosis, higher prevalence of some precipitating events (bacterial infections, active alcoholism), and higher level of systemic inflammation. ACLF is a new entity also because it cannot be explained entirely by severe sepsis or severe alcoholic hepatitis; a large proportion of cases are of unknown origin. ACLF should be considered as a whole that includes subcategories such as severe sepsis, severe alcoholic hepatitis, and others, which have yet to be defined. ACLF is a relatively common syndrome because it occurs in 31% of hospitalized patients with cirrhosis who have an acute complication of their liver disease. In these patients, ACLF is the most common cause of death., (Copyright © 2015 AGA Institute. Published by Elsevier Inc. All rights reserved.)

Background & Aims: Acute-on-chronic liver failure (ACLF) is a frequent syndrome (30% prevalence), characterized by acute decompensation of cirrhosis, organ failure(s) and high short-term mortality. This study develops and validates a specific prognostic score for ACLF patients., Methods: Data from 1349 patients included in the CANONIC study were used. First, a simplified organ function scoring system (CLIF Consortium Organ Failure score, CLIF-C OFs) was developed to diagnose ACLF using data from all patients. Subsequently, in 275 patients with ACLF, CLIF-C OFs and two other independent predictors of mortality (age and white blood cell count) were combined to develop a specific prognostic score for ACLF (CLIF Consortium ACLF score [CLIF-C ACLFs]). A concordance index (C-index) was used to compare the discrimination abilities of CLIF-C ACLF, MELD, MELD-sodium (MELD-Na), and Child-Pugh (CPs) scores. The CLIF-C ACLFs was validated in an external cohort and assessed for sequential use., Results: The CLIF-C ACLFs showed a significantly higher predictive accuracy than MELDs, MELD-Nas, and CPs, reducing (19-28%) the corresponding prediction error rates at all main time points after ACLF diagnosis (28, 90, 180, and 365 days) in both the CANONIC and the external validation cohort. CLIF-C ACLFs computed at 48 h, 3-7 days, and 8-15 days after ACLF diagnosis predicted the 28-day mortality significantly better than at diagnosis., Conclusions: The CLIF-C ACLFs at ACLF diagnosis is superior to the MELDs and MELD-Nas in predicting mortality. The CLIF-C ACLFs is a clinically relevant, validated scoring system that can be used sequentially to stratify the risk of mortality in ACLF patients., (Copyright © 2014 European Association for the Study of the Liver.

Background & Aims: There is no histologic classification system to determine prognoses of patients with alcoholic hepatitis (AH). We identified histologic features associated with disease severity and created a histologic scoring system to predict short-term (90-day) mortality., Methods: We analyzed data from 121 patients admitted to the Liver Unit (Hospital Clinic, Barcelona, Spain) from January 2000 to January 2008 with features of AH and developed a histologic scoring system to determine the risk of death using logistic regression. The system was tested and updated in a test set of 96 patients from 5 academic centers in the United States and Europe, and a semiquantitative scoring system called the Alcoholic Hepatitis Histologic Score (AHHS) was developed. The system was validated in an independent set of 109 patients. Interobserver agreement was evaluated by weighted κ statistical analysis., Results: The degree of fibrosis, degree of neutrophil infiltration, type of bilirubinostasis, and presence of megamitochondria were independently associated with 90-day mortality. We used these 4 parameters to develop the AHHS to identify patients with a low (0-3 points), moderate (4-5 points), or high (6-9 points) risk of death within 90 days (3%, 19%, and 51%, respectively; P < .0001). The AHHS estimated 90-day mortality in the training and test sets with an area under the receiver operating characteristic value of 0.77 (95% confidence interval, 0.71-0.83). Interrater agreement values were 0.65 for fibrosis, 0.86 for bilirubinostasis, 0.60 for neutrophil infiltration, and 0.46 for megamitochondria. Interestingly, the type of bilirubinostasis predicted the development of bacterial infections., Conclusions: We identified histologic features associated with the severity of AH and developed a patient classification system that might be used in clinical decision making., (Copyright © 2014 AGA Institute.

A questionnaire to assess the clinical choice of ascites treatment in cirrhosis was distributed to 1473 participants in an EASL meeting. The response rate (295, 20%) was considered satisfactory in view of the heterogeneity of the persons attending this event. Most participants (86.4%) in the survey were hepatologists and gastroenterologists. The following conclusions of the survey are noteworthy: (1) The objective of ascites therapy was to eliminate completely or almost completely the ascitic fluid for 49% of responders and to decrease ascites volume to an acceptable level of patient comfort for 48%; (2) The classical progressive therapeutic schedule of ascites is rarely used; (3) Following mobilisation of ascites, most (82%) maintain patients on diuretic therapy to avoid reaccumulation of ascites; (4) Only 5% of participants did not use paracentesis to manage ascites in cirrhosis. This was the therapeutic procedure most frequently used for patients with refractory ascites; (5) Although the most acceptable definition of refractory ascites was ascites which cannot be mobilized by maximal medical treatment, a significant proportion of participants also considered that intractable ascites due to diuretic-induced complications and recidivant ascites should be included in the definition; (6) The proportions of participants prescribing prophylactic therapy, mainly low sodium diet, to compensated patients with and without a past history of ascites were 68% and 16%, respectively.
