Abstract
Acute-on-chronic liver failure (AoCLF) represents a newly defined entity in patients with liver disease leading to multiple organ failures and increased mortality. To date, no universally accepted definition exists, and different academic societies developed guidelines on the early diagnosis and classification of AoCLF. Recently published trials focused on factors associated with a poor outcome and on the development of severity scores aimed to identify patients who may benefit for advanced monitoring and treatment. No specific therapies are demonstrated to improve survival, and liver transplantation (LT) remains the only treatment associated with improved outcome. Our review focuses on current evidence for early diagnosis and prognostication of disease in patients with AoCLF, as well of criteria for intensive care unit admission, indication, and futility markers of LT, as well as bridging therapy and optimal timing of surgery.

Abstract
The frequency of acquired liver injury and failure in critical illness has been significantly increasing over recent decades. Currently, liver injury and failure are observed in up to 20% of patients in intensive care units and are associated with significantly increased morbidity and mortality. Secondary forms of liver injury in critical illness are divided primarily into cholestatic, hypoxic, or mixed forms. Therefore, sufficient knowledge of underlying alterations (e.g., hemodynamic, inflammatory, or drug induced) is key to a better understanding of clinical manifestations, prognostic implications, as well as diagnostic and therapeutic options of acquired liver injury and failure. This review provides a structured approach for the evaluation and treatment of acquired liver injury and failure in critically ill patients.

Abstract
PURPOSE Acute liver failure (ALF) and acute on chronic liver failure (ACLF) are associated with significant mortality and morbidity. Extracorporeal liver support (ECLS) devices have been used as a bridge to liver transplant; however, the efficacy and safety of ECLS are unclear. We conducted a systematic review and meta-analysis of randomized controlled trials (RCTs) to examine the efficacy and safety of ECLS in liver failure. METHODS We searched MEDLINE, EMBASE and Cochrane Central Register of Controlled Trials from inception through March 13, 2019. RCTs comparing ECLS to usual care in ALF or ACLF were included. We used the Grading of Recommendations Assessment, Development and Evaluation approach to assess the certainty of the evidence. RESULTS We identified 25 RCTs (1796 patients). ECLS use was associated with reduction in mortality (RR 0.84; 95% CI 0.74, 0.96, moderate certainty) and improvement in hepatic encephalopathy (HE) (RR 0.71; 95% CI 0.60, 0.84, low certainty) in patients with ALF or ACLF. The effect of ECLS on hypotension (RR 1.46; 95% CI 0.98, 2.2, low certainty), bleeding (RR 1.21; 95% CI 0.88, 1.66, moderate certainty), thrombocytopenia (RR 1.62; 95% CI 1.0, 2.64, very low certainty) and line infection (RR 1.92; 95% CI 0.11, 33.44, low certainty) was uncertain. CONCLUSIONS ECLS may reduce mortality and improve HE in patients with ALF and ACLF. The effect on other outcomes is uncertain. However, the evidence is limited by risk of bias and imprecision, and larger trials are needed to better determine the effect of ECLS on patient-important outcomes.

Abstract
BACKGROUND Acute-on-chronic liver failure (ACLF) is a common complication of cirrhosis characterized by single or multiple organ failures and high short-term mortality. Treatment of ACLF consists of standard medical care (SMC) and organ(s) support. Whether the efficacy of artificial liver support (ALS) depends on the severity of ACLF or on the intensity of this treatment, or both, is unclear. This study aimed to further assess these issues. METHODS We performed an individual patient data meta-analysis assessing the efficacy of Molecular Adsorbent Recirculating System (MARS) in ACLF patients enrolled in prior randomized control trials (RCTs). The meta-analysis was designed to assess the effect of patient severity (ACLF grade) and treatment intensity [low-intensity therapy (LIT), SMC alone or SMC plus ⩽ 4 MARS sessions, high-intensity therapy (HIT), SMC plus > 4 MARS sessions] on mortality. RESULTS Three RCTs suitable for the meta-analysis (n = 285, ACLF patients = 165) were identified in a systematic review. SMC plus MARS (irrespective of the number of sessions) did not improve survival compared with SMC alone, neither in the complete population nor in the ACLF patients. Survival, however, was significantly improved in the subgroup of patients receiving HIT both in the entire cohort (10-day survival: 98.6% versus 82.8%, p = 0.001; 30-day survival: 73.9% versus 64.3%, p = 0.032) and within the ACLF patients (10-day survival: 97.8% versus 78.6%, p = 0.001; 30-day survival: 73.3% versus 58.5%, p = 0.041). Remarkably, HIT increased survival independently of ACLF grade. Independent predictors of survival were age, Model for End-Stage Liver Disease (MELD), ACLF grade, number of MARS sessions received, and intensity of MARS therapy. CONCLUSION HIT with albumin dialysis may improve survival in patients with ACLF. Appropriate treatment schedules should be determined in future clinical trials.

Abstract
Background Extracorporeal liver support therapies (ELS) are technical options (for bridge-to-recovery as well as bridge-to-transplant) in patients with acute liver dysfunction (e.g. acute liver failure (ALF), acute-on chronic liver failure (AoCLF) or decompensated chronic liver disease (decomp. CLD)) to reduce effects of failing hepatic detoxification functions. The present study investigates the real-life utilization of ELS (annual incidences), mortality rates as well as data regarding specific populations of liver transplantation in Germany. Methods Data on patient cases receiving extracorporeal liver support therapy were identified in a nationwide data set from the Federal statistical Office of Germany from 1 January 2007 through 31 December 2015 and analyzed regarding in-hospital mortality, age- and sex-specific distribution and use of ELS in the context of liver transplantation. Mortality rates in patients with primary acute liver dysfunction and secondary acute liver dysfunction (in the context of cardiothoracic surgery) were evaluated. Results Annual incidences of ELS use remained stable between 0.39/100.000 in 2007 and 0.47/100.000 ELS in 2015. In-hospital mortality rate was 51.49% in the 2886 evaluated patient cases. Mortality was higher in men (56.04%) than in women (43.70) in the observed time period between 2007 and 2015. ELS utilization and case-related liver transplantation rates were low (12.47%). Since 2012, the annual numbers for ELS therapy in cardiosurgical patients exceeded the frequency of ELS utilization in cases of primary liver dysfunction (mortality rates: 68.39% versus 40.63%). Conclusions ELS utilization remained stable between 2007 and 2015. Mortality rates are high in this patient population of acute liver dysfunction, especially in combination with case-related cardiothoracic surgery. ELS is rarely used in the setting of liver transplantation. In 2015, more than 50% of all ELS cases in Germany were performed in the context of cardiothoracic surgery.

Abstract
The first consensus report of the working party of the Asian Pacific Association for the Study of the Liver (APASL) set up in 2004 on acute-on-chronic liver failure (ACLF) was published in 2009. With international groups volunteering to join, the "APASL ACLF Research Consortium (AARC)" was formed in 2012, which continued to collect prospective ACLF patient data. Based on the prospective data analysis of nearly 1400 patients, the AARC consensus was published in 2014. In the past nearly four-and-a-half years, the AARC database has been enriched to about 5200 cases by major hepatology centers across Asia. The data published during the interim period were carefully analyzed and areas of contention and new developments in the field of ACLF were prioritized in a systematic manner. The AARC database was also approached for answering some of the issues where published data were limited, such as liver failure grading, its impact on the 'Golden Therapeutic Window', extrahepatic organ dysfunction and failure, development of sepsis, distinctive features of acute decompensation from ACLF and pediatric ACLF and the issues were analyzed. These initiatives concluded in a two-day meeting in October 2018 at New Delhi with finalization of the new AARC consensus. Only those statements, which were based on evidence using the Grade System and were unanimously recommended, were accepted. Finalized statements were again circulated to all the experts and subsequently presented at the AARC investigators meeting at the AASLD in November 2018. The suggestions from the experts were used to revise and finalize the consensus. After detailed deliberations and data analysis, the original definition of ACLF was found to withstand the test of time and be able to identify a homogenous group of patients presenting with liver failure. New management options including the algorithms for the management of coagulation disorders, renal replacement therapy, sepsis, variceal bleed, antivirals and criteria for liver transplantation for ACLF patients were proposed. The final consensus statements along with the relevant background information and areas requiring future studies are presented here.

Artru F, Samuel D. Approaches for patients with very high MELD scores. JHEP Rep 2019; 1:53-65. [PMID: 32039352 PMCID: PMC7001538 DOI: 10.1016/j.jhepr.2019.02.008] [Citation(s) in RCA: 17] [Impact Index Per Article: 3.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/20/2018] [Revised: 01/31/2019] [Accepted: 02/04/2019] [Indexed: 02/08/2023] Open
Abstract
In the era of the "sickest first" policy, patients with very high model for end-stage liver disease (MELD) scores have been increasingly admitted to the intensive care unit with the expectation that they will receive a liver transplant (LT) in the absence of improvement on supportive therapies. Such patients are often admitted in a context of acute-on-chronic liver failure with extrahepatic failures. Sequential assessment of scores or classification based on organ failures within the first days after admission help to stratify the risk of mortality in this population. Although the prognosis of severely ill cirrhotic patients has recently improved, transplant-free mortality remains high. LT is still the only curative treatment in this population. Yet, the increased relative scarcity of graft resource must be considered alongside the increased risk of losing a graft in the initial postoperative period when performing LT in "too sick to transplant" patients. Variables associated with poor immediate post-LT outcomes have been identified in large studies. Despite this, the performance of scores based on these variables is still insufficient. Consideration of a patient's comorbidities and frailty is an appealing predictive approach in this population that has proven of great value in many other diseases. So far, local expertise remains the last safeguard to LT. Using this expertise, data are accumulating on favourable post-LT outcomes in very high MELD populations, particularly when LT is performed in a situation of stabilization/improvement of organ failures in selected candidates. The absence of "definitive" contraindications and the control of "dynamic" contraindications allow a "transplantation window" to be defined. This window must be identified swiftly after admission given the poor short-term survival of patients with very high MELD scores. In the absence of any prospect of LT, withdrawal of care could be discussed to ensure respect of patient life, dignity and wishes.

Abstract
Extracorporeal liver support (ECLS) emerged from the need stabilize high-acuity liver failure patients with the highest risk of death. The goal is to optimize the hemodynamic, neurologic, and biochemical parameters in preparation for transplantation or to facilitate spontaneous recovery. Patients with acute liver failure and acute-on-chronic liver failure stand to benefit from these devices, especially because they have lost many of the primary functions of the liver, including detoxifying the blood of various endogenous and exogenous substances, manufacturing circulating proteins, secreting bile, and storing energy. Existing ECLS devices are designed to mimic some of these functions.

Abstract
Hepatic encephalopathy (HE) is a serious complication of liver disease. To establish a model for predicting 3-month mortality in patients with HE in China. This retrospective study included 609 patients with HE admitted to the Peoples' Hospital, Liaocheng City, China (August 2006 to January 2016). Patients were allocated to a modeling (n = 409) or validation (n = 200) group. Demographic/clinical characteristics, laboratory test results, Model for End Stage Liver Disease (MELD) score and Child-Turcotte-Pugh (CTP) score were extracted from medical records. A model for predicting death within 3 months after admission was established using logistic regression analysis (modeling group). Model validity (validation group) was assessed using receiver operating characteristic (ROC) curve analysis. 270/409(66.0%) patients died in the modeling group and 142/203(70.0%) died in the validation group. Compared with survivors, patients who died had more severe HE, and higher MELD score, CTP score, incidence of complications including hepatorenal syndrome (HRS) and upper gastrointestinal bleeding, and values for laboratory parameters including red blood cell count(RBC) and total bilirubin(TBIL)(P < 0.05). Regression analysis revealed RBC, TBIL, HE stage, HRS and upper gastrointestinal bleeding as independent factors associated with death (P < 0.05). The area under the ROC curve (AUC) for the model was 0.931.The model had a higher Youden index than MELD or CTP scores and predicted death in the validation group with a sensitivity of 83.1% and specificity of 93.4%. The established model has superior performance to MELD and CTP scores for predicting mortality in patients with HE.

Abstract
This chapter describes the general treatment and immune principles and internal management for AECHB and HBV ACLF, including ICU monitoring, general supportive medications/nutrition/nursing, immune therapy, artificial liver supportive systems, hepatocyte/stem cell, and liver transplant, management for special populations, frequently clinical complications and the utilization of Chinese traditional medicines.Early clinical indicators of severe hepatitis B include acratia, gastrointestinal symptoms, a daily increase in serum bilirubin >1 mg/dL, toxic intestinal paralysis, bleeding tendency and mild mind anomaly or character change, and the presence of other diseases inducing severe hepatitis. Laboratory indicators include T-Bil, PTA, cholinesterase, pre-albumin and albumin. The roles of immune indicators (such as IL-6, TNF-α, and fgl2), gene polymorphisms, HBV genotypes, and gene mutations as early clinical indicators. Intensive Care Unit monitor patients with severe hepatitis include intracranial pressure, infection, blood dynamics, respiratory function, renal function, blood coagulation function, nutritional status and blood purification process. Nursing care should not only include routine care, but psychological and special care (complications). Nutrition support and nursing care should be maintained throughout treatment for severe hepatitis. Common methods of evaluating nutritional status include direct human body measurement, creatinine height index (CHI) and subject global assessment of nutrition (SGA). Malnourished patients should receive enteral or parenteral nutrition support. Immune therapies for severe hepatitis include promoting hepatocyte regeneration (e.g. with glucagon, hepatocyte growth factor and prostaglandin E1), glucocorticoid suppressive therapy, and targeting molecular blocking. Corticosteroid treatment should be early and sufficient, and adverse drug reactions monitored. Treatments currently being investigated are those targeting Toll-like receptors, NK cell/NK cell receptors, macrophage/immune coagulation system, CTLA-4/PD-1 and stem cell transplantation. In addition to conventional drugs and radioiodine, corticosteroids and artificial liver treatment can also be considered for severe hepatitis patients with hyperthyreosis. Patients with gestational severe hepatitis require preventive therapy for fetal growth restriction, and it is necessary to choose the timing and method of fetal delivery. For patients with both diabetes and severe hepatitis, insulin is preferred to oral antidiabetic agents to control blood glucose concentration. Liver toxicity of corticosteroids and immune suppressors should be monitored during treatment for severe hepatitis in patients with connective tissue diseases including SLE, RA and sicca syndrome. Patient with connective tissue diseases should preferably be started after the antiviral treatment with nucleos(t)ide analogues. An artificial liver can improve patients’ liver function; remove endotoxins, blood ammonia and other toxins; correct amino acid metabolism and coagulation disorders; and reverse internal environment imbalances. Non-bioartificial livers are suitable for patients with early and middle stage severe hepatitis; for late-stage patients waiting for liver transplantation; and for transplanted patients with rejection reaction or transplant failure. The type of artificial liver should be determined by each patient’s condition and previous treatment purpose, and patients should be closely monitored for adverse reactions and complications. Bio- and hybrid artificial livers are still under development. MELD score is the international standard for choosing liver transplantation. Surgical methods mainly include the in situ classic type and the piggyback type; transplantation includes no liver prophase, no liver phase or new liver phase. Preoperative preparation, management of intraoperative and postoperative complications and postoperative long-term treatment are keys to success. Severe hepatitis belongs to the categories of “acute jaundice”, “scourge jaundice”, and “hot liver” in traditional Chinese medicine. Treatment methods include Chinese traditional medicines, acupuncture and acupoint injection, external application of drugs, umbilical compress therapy, drip, blow nose therapy, earpins, and clysis. Dietary care is also an important part of traditional Chinese medicine treatment.

Abstract
INTRODUCTION The mortality rate in patients with severe liver dysfunction with no option of transplantation is unacceptably high. The main aim of this study was to evaluate the usefulness of applying extracorporeal liver support (ECLS) techniques in this group of patients. MATERIAL AND METHODS Data from hospital admissions of 101 patients with severe liver dysfunction who were admitted to the department of Anaesthesiology and intensive therapy between 2006 and 2015 were retrospectively analysed. The study group was divided into two subgroups. Standard Medical therapy (SMT) was a subgroup of patients receiving standard Medical therapy, and SMT + ECLS was a subgroup containing patients receiving standard medical therapy complemented by at least one extracorporeal liver support procedure. RESULTS Significantly lower intensive care unit (ICU) mortality and 30-day mortality rates were found in the SMT + ECLS subgroup (p = 0.0138 and p = 0.0238 respectively). No difference in 3-month mortality was identified between the two groups. In a multivariate model, independent risk factors for ICU mortality proved to be the SOFA score and prothrombin time. The highest discriminatory power for ICU mortality was demonstrated for the SOFA score, followed by APACHE II, SAPS II, MELD UNOS and GCS scores. For 30-day mortality, however, the best discriminatory power was shown for the SAPS II score, followed by SOFA, APACHE II, MELD UNOS and GCS scores. CONCLUSIONS Further studies are needed to assess the contribution of non-biological extracorporeal liver support procedures to a decrease in mortality rates in the population of patients with severe liver dysfunction.

Abstract
Hyperammonemia plays a key role in the pathophysiology of hepatic encephalopathy (HE) and most HE treatments are ammonia-lowering drugs. However, the usefulness of measuring ammonemia in routine practice remains controversial and not recommended systematically even when neurological symptoms are present. First, ammonemia measurement should be carefully performed in order to avoid a falsely elevated result. When performed, a normal ammonemia in a cirrhotic patient with neurological symptoms should lead to reconsider the diagnosis of HE. Indeed, literature data show that most cirrhotic patients with HE have an elevated ammonemia, which is however individually poorly correlated with the severity of symptoms. Nevertheless, elevated ammonemia seems to be a factor of bad prognosis in cirrhosis. A decrease in ammonemia after treatments is well proven but it is not determined whether it is associated with clinical efficacy. Repeated measurements could be useful in this context, especially in non-responders, to help differentiating other causes of encephalopathy, such as drug induced. In acute liver failure, the prognostic value of hyperammonemia is well described and could help an early recognition the most severe forms of this disease. We will also discuss how integrating ammonemia into the diagnostic work-up of liver failure and/or encephalopathy. Ammonemia is also essential to diagnose urea cycle disorders or drug toxicity that both need specific interventions.

Abstract
Hepatic encephalopathy is a brain dysfunction caused by liver insufficiency and/or portal-systemic shunt; it manifests as a wide spectrum of neurological or psychiatric abnormalities ranging from subclinical alterations to coma. It should be differentiated from other neurological/psychiatric disorders that can occur in patients with liver disease. Its classification needs to take into account the underlying condition, severity, course, precipitating factors, and-possibly-sensitivity to ammonia-lowering agents.

Abstract
Acute fatty liver of pregnancy (AFLP) continues to raise special concerns since its first post-mortem description by Sheehan in 1940. While early diagnosis and expedite delivery are the cornerstone of management, this condition remains fatal for both mother and fetus. Acute fulminant liver failure is the most serious and life-threatening AFLP-related complication and can require liver transplant despite aggressive supportive management. In lieu of transplant, therapeutic plasma exchange (PE) has emerged as a life-saving alternative and has, in few reports, demonstrated efficacy for the reversal of this dangerous condition. Here we present a case report of a patient diagnosed with fulminant liver failure complicating an AFLP and progressed to severe hepatic encephalopathy who was successfully treated with five rounds of plasma exchange.

Abstract
UNLABELLED 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.

Abstract
Acute liver failure (ALF) is a rare condition with fatal outcome. Characteristic is rapid onset of liver damage without preexisting liver diseases, including hepatic encephalopathy and coagulopathy. Early and correct diagnosis is essential for further management of patients, since diagnosis impacts therapy choice. Survival of patients with ALF has improved dramatically due to advances in critical care medicine and the use of liver transplantation.

Abstract
OBJECTIVES Standard intensive care treatment is inadequate to keep children with liver failure alive without catastrophic complications to ensure successful transplant, as accumulation of endogenous protein-bound toxins often lead to hepatic encephalopathy, hepatorenal syndrome, cardiovascular instability, and multiple organ failure. Given paucity of proven treatment modalities for liver failure, blood purification using different extracorporeal treatments as a bridge to transplantation is used, but studies evaluating the safety and efficacy of combination of these therapies, especially in pediatric liver failure, are lacking. We describe our experience at a major tertiary children's hospital, where a unique hybrid extracorporeal treatment protocol has been instituted and followed for acute liver failure or acute-on-chronic liver failure as a bridge to transplantation. This protocol combines high-flux continuous renal replacement therapy for hyperammonemia, therapeutic plasma exchange for coagulopathy, and albumin-assisted dialysis (molecular adsorbent recirculating system) for hepatic encephalopathy. DESIGN Retrospective observational study. SETTING Freestanding tertiary children's hospital and liver transplant referral center. PATIENTS All patients with acute liver failure/acute-on-chronic liver failure receiving hybrid extracorporeal therapy over 24 months. INTERVENTION Hybdrid extracorporeal therapy. MEASUREMENTS AND MAIN RESULTS Fifteen children (age 3 yr [0.7-9 yr]; 73% male) with acute liver failure/acute-on-chronic liver failure who were either listed or actively considered for listing and met our protocol criteria were treated with hybrid extracorporeal therapy; 93% were ventilated, and 80% were on vasoactive support. Of these, two patients recovered spontaneously, four died prior to transplant, and nine were successfully transplanted; 90-day survival post orthotopic liver transplant was 100%. Overall survival to hospital discharge was 73%. CONCLUSIONS Hybrid extracorporeal therapies can be effectively implemented in pediatric liver failure as a bridge to transplantation. Overall complexity and heavy resource utilization need to be carefully considered in instituting these therapies in suitable candidates.

Abstract
Hepatic encephalopathy (HE) is a major cause of morbidity in cirrhosis. However, its severity assessment is often subjective, which needs to be studied systematically. The aim was to determine how accurately trainee and nontrainee practitioners grade and manage HE patients throughout its severity. We performed a survey study using standardized simulated patient videos at 4 US and 3 Canadian centers. Participants were trainees (gastroenterology/hepatology fellows) and nontrainees (faculty, nurse practitioners, physician assistants). We determined the accuracy of HE severity identification and management options between grades <2 or ≥2 HE and trainees/nontrainees. In total, 108 respondents (62 trainees, 46 nontrainees) were included. For patients with grades <2 versus ≥2 HE, a higher percentage of respondents were better at correctly diagnosing grades ≥2 compared with grades <2 (91% versus 64%; P < 0.001). Specialized cognitive testing was checked significantly more often in grades <2, whereas more aggressive investigation for precipitating factors was ordered in HE grades >2. Serum ammonia levels were ordered in almost a third of grade ≥2 patients. For trainees and nontrainees, HE grades were identified similarly between groups. Trainees were less likely to order serum ammonia and low-protein diets, more likely to order rifaximin, and more likely to perform a more thorough workup for precipitating factors compared with nontrainee respondents. There was excellent concordance in the classification of grade ≥2 HE between nontrainees versus trainees, but lower grades showed discordance. Important differences were seen regarding blood ammonia, specialized testing, and nutritional management between trainees and nontrainees. These results have important implications at the patient level, interpreting multicenter clinical trials, and in the education of practitioners. Liver Transplantation 24 587-594 2018 AASLD.

Abstract
Hepatic encephalopathy (HE) is a common complication of liver dysfunction, including acute liver failure and liver cirrhosis. HE presents as a spectrum of neuropsychiatric symptoms ranging from subtle fluctuating cognitive impairment to coma. It is a significant contributor of morbidity in patients with liver disease. HE is observed in acute liver failure, liver bypass procedures, for example, shunt surgry and transjugular intrahepatic portosystemic shunt, and cirrhosis. These are classified as Type A, B and C HE, respectively. HE can also be classified according to whether its presence is overt or covert. The pathogenesis is linked with ammonia and glutamine production, and treatment is based on mechanisms to reduce the formation and/or removal of these compounds. There is no specific diagnostic test for HE, and diagnosis is based on clinical suspicion, excluding other causes and use of clinical tests that may support its diagnosis. Many tests are used in trials and experimentally, but have not yet gained universal acceptance. This review focuses on the definitions, pathogenesis and treatment of HE. Consideration will be given to existing treatment, including avoidance of precipitating factors and novel therapies such as prebiotics, probiotics, antibiotics, laxatives, branched-chain amino acids, shunt embolization and the importance of considering liver transplant in appropriate cases.

Abstract
We report a case of a 26-year-old man with no significant medical history, who presented with fatigue, pruritus, jaundice, dark urine and clay colored stool for one month. He had been taking methyl-1-etiochoenolol-epietiocholanolone, an androgenic anabolic steroid (AAS). He was initially found to have a total bilirubin (Tbili) of 6 mg/dL. He discontinued the AAS but the patients’ symptoms worsened and Tbili increased to 36 mg/d. This prompted inpatient management of his drug-induced liver injury (DILI). Molecular adsorbent recirculating system (MARS) is an extracorporeal liver support system that replaces the detoxification function of the liver. The patient was initiated on a 4-day trial of MARS therapy. Over the course of his therapy, he clinically improved and his Tbili decreased to 20.7 mg/dL. At follow-up, his symptoms resolved and Tbili was 3.3 mg/dl. This case demonstrates the efficacy of MARS in treating severe cholestatic DILI refractory to standard medical therapy.

Abstract
Patients with cirrhosis who are awaiting liver transplantation (LT) are at high risk for developing critical illnesses. Current liver allocation policies that dictate a "sickest first" approach coupled with a mismatch between need and availability of organs result in longer wait times, and thus, patients are becoming increasingly ill while awaiting organ transplantation. Even patients with well-compensated cirrhosis may suffer acute deterioration; the syndrome of acute-on-chronic liver failure (ACLF) results in multisystem organ dysfunction and a marked increase in associated short-term morbidity and mortality. For patients on transplant waiting lists, the development of multisystem organ failure may eliminate candidacy for transplant by virtue of being "too sick" to safely undergo transplantation surgery. The goals of intensive care management of patients suffering ACLF are to rapidly recognize and treat inciting events (eg, infection and bleeding) and to aggressively support failing organ systems to ensure that patients may successfully undergo LT. Management of the critically ill ACLF patient awaiting transplantation is best accomplished by multidisciplinary teams with expertise in critical care and transplant medicine. Such teams are well suited to address the needs of this unique patient population and to identify patients who may be too ill to proceed to transplantation surgery. The focus of this review is to identify the common complications of ACLF and to describe our approach management in critically ill patients awaiting LT in our centers.

Abstract
Supplemental Digital Content is available in the text. Objectives: Acute-on-chronic liver failure is associated with numerous consecutive organ failures and a high short-term mortality rate. Molecular adsorbent recirculating system therapy has demonstrated beneficial effects on the distinct symptoms, but the associated mortality data remain controversial. Design: Retrospective analysis of acute-on-chronic liver failure patients receiving either standard medical treatment or standard medical treatment and molecular adsorbent recirculating system. Secondary analysis of data from the prospective randomized Recompensation of Exacerbated Liver Insufficiency with Hyperbilirubinemia and/or Encephalopathy and/or Renal Failure trial by applying the recently introduced Chronic Liver Failure-criteria. Setting: Medical Departments of University Hospital Muenster (Germany). Patients: This analysis was conducted in two parts. First, 101 patients with acute-on-chronic liver failure grades 1–3 and Chronic Liver Failure-C-Organ Failure liver subscore equals to 3 but stable pulmonary function were identified and received either standard medical treatment (standard medical treatment, n = 54) or standard medical treatment and molecular adsorbent recirculating system (n = 47) at the University Hospital Muenster. Second, the results of this retrospective analysis were tested against the Recompensation of Exacerbated Liver Insufficiency with Hyperbilirubinemia and/or Encephalopathy and/or Renal Failure trial. Interventions: Standard medical treatment and molecular adsorbent recirculating system. Measurements and Main Results: Additionally to improved laboratory variables (bilirubin and creatinine), the short-term mortality (up to day 14) of the molecular adsorbent recirculating system group was significantly reduced compared with standard medical treatment. A reduced 14-day mortality rate was observed in the molecular adsorbent recirculating system group (9.5% vs 50.0% with standard medical treatment; p = 0.004), especially in patients with multiple organ failure (acute-on-chronic liver failure grade 2–3). Concerning the affected organ system, this effect of molecular adsorbent recirculating system on mortality was particularly evident among patients with increased kidney, brain, or coagulation Chronic Liver Failure-C-Organ Failure subscores. Subsequent reanalysis of the Recompensation of Exacerbated Liver Insufficiency with Hyperbilirubinemia and/or Encephalopathy and/or Renal Failure dataset with adoption of the Chronic Liver Failure-classification resulted in similar findings. Conclusions: Molecular adsorbent recirculating system treatment was associated with an improved short-term survival of patients with acute-on-chronic liver failure and multiple organ failure. Among these high-risk patients, molecular adsorbent recirculating system treatment might bridge to liver recovery or liver transplantation.

Abstract
Some patients with veno-occlusive disease (VOD) have multiorgan dysfunction, and multiple teams are involved in their daily care in the pediatric intensive care unit. Cardiorespiratory dysfunction is critical in these patients, requiring immediate action. The decision of whether to use a noninvasive or an invasive ventilation strategy may be difficult in the setting of mucositis or other comorbidities in patients with VOD. Similarly, monitoring of organ functions may be very challenging in these patients, who may have fulminant hepatic failure with or without hepatic encephalopathy complicated by delirium and/or infections. In this final guideline of our series on supportive care in patients with VOD, we address some of these questions and provide evidence-based recommendations on behalf of the Pediatric Acute Lung Injury and Sepsis Investigators and Pediatric Blood and Marrow Transplantation Consortium Joint Working Committees.

Abstract
Hepatic encephalopathy (HE) is a serious neuropsychiatric complication of cirrhosis and/or porto-systemic shunting. The clinical symptoms are widely variable, extending from subtle impairment in mental state to coma. The utility of categorizing the severity of HE accurately and efficiently serves not only to provide practical functional information about the current clinical status of the patient but also gives valuable prognostic information. In the past 20–30 years, there has been rapid progress in understanding the pathophysiological basis of HE; however, the lack of direct correlation between pathogenic factors and the severity of HE make it difficult to select appropriate therapy for HE patients. In this review, we will discuss the classification system and its limitations, the neuropsychometric assessments and their challenges, as well as the present knowledge on the pathophysiological mechanisms. Despite the many prevalent hypotheses around the pathogenesis of the disease, most treatments focus on targeting and lowering the accumulation of ammonia as well as inflammation. However, treatment of minimal HE remains a huge unmet need and a big concerted effort is needed to better define this condition to allow the development of new therapies. We review the currently available therapies and future approaches to treat HE as well as the scientific and clinical data that support their effectiveness.

Abstract
Hepatic encephalopathy is a spectrum of reversible neuropsychiatric abnormalities, seen in patients with liver dysfunction and/or portosystemic shunting. One of the most debilitating complications of cirrhosis, encephalopathy affects 30-45% of cirrhotics. In addition to significantly affecting the lives of patients and their caregivers, it is also associated with increased morbidity and mortality as well as significant utilization of health care resources. In this paper, we provide an overview on the pathophysiology, diagnosis, management and newer therapies of hepatic encephalopathy.

Abstract
Artificial (nonbiological) extracorporeal liver support devices aim to remove albumin-bound and water-soluble toxins to restore and preserve hepatic function and mitigate or limit the progression of multiorgan failure while hepatic recovery or liver transplant occurs. The following beneficial effects have been documented: improvement of jaundice, amelioration of hemodynamic instability, reduction of portal hypertension, and improvement of hepatic encephalopathy. The only randomized prospective multicenter controlled trial to show an improvement in transplant-free survival was for high-volume plasmapheresis. Biological (cell-based) extracorporeal liver support systems aim to support the failing liver through detoxification and synthetic function and warrant further study for safety and benefit.

Abstract
Extracorporeal liver support systems (ELSS), encompassing artificial and bioartificial devices, have been used for decades, with the aim of supporting patients with acute liver failure and acute-on chronic liver failure, as a bridge to recovery (acute liver failure only) or liver transplantation, in an era of organ donation shortage. Although biochemical efficacy has been consistently demonstrated by these devices, translation into clinical and survival benefits has been unclear, due to study limitations and lack of reliable prognostic scoring in liver failure. Consequently, extracorporeal devices are not widely accepted as routine therapy in adult liver failure. Recent large multicentre trials using artificial liver systems have not revealed beneficial outcomes associated with albumin dialysis but plasma exchange practices have shown some potential. In paediatric liver failure, data on extracorporeal systems is scarce, comprising few reports on albumin dialysis (namely, Molecular Adsorbent Recirculating System; MARS) and plasma exchange. When extrapolating data from adult studies differences in disease presentation, aetiology, prognosis and the suitability, and safety of such devices in children must be considered. The aim of this review is to critically appraise current practices of extracorporeal liver support systems to help determine efficacy in paediatric liver failure.

Abstract
BACKGROUND Hepatic encephalopathy (HE) is associated with poor prognosis and treatment of HE is primarily directed at the reduction of the blood ammonia levels. The study evaluated the efficacy and safety of albumin plus lactulose versus lactulose alone for treatment of overt HE. METHODS In prospective randomized controlled trial, 120 patients with overt HE were randomized in two groups: group A lactulose plus albumin (n = 60) and group B lactulose alone (n = 60). Primary end point was complete reversal of HE, and secondary end points were mortality and hospital stay. RESULTS A total of 120 patients (mean age 40.4 ± 9.3 years) were included in this study. Thirty-six (30%) patients were in Child-Turcotte-Pugh (CTP) class B, and 84 (70%) were in CTP Class C. Mean CTP score was 9.8 ± 2.1, and model for end-stage liver disease score was 26.1 ± 5.3. Twenty seven (22.5%) had grade 2, 57 (47.5%) had grade 3, and 36 (30%) had grade 4 HE at the time of admission. Forty-five (75%) patients in group A compared with 32 (53.3%) patients in group B had complete reversal of HE (P = 0.03). Mortality was significantly lower in lactulose plus albumin group (11[18.3%]) versus lactulose alone (19 [31.6%], [P < 0.05]). There was significant decrease in levels of arterial ammonia, interleukin-6, interleukin-18, tumor necrosis factor-alpha, and endotoxins after treatment in both groups; however, the delta decrease was significantly higher in group A compared with group B. Hospital stay was shorter in group A. CONCLUSIONS Combination of lactulose plus albumin is more effective than lactulose alone in treatment of overt HE.

Molecular adsorbent recirculating system (MARS) in acute liver injury and graft dysfunction: Results from a case-control study. PLoS One 2017; 12:e0175529. [PMID: 28403210 PMCID: PMC5389829 DOI: 10.1371/journal.pone.0175529] [Citation(s) in RCA: 25] [Impact Index Per Article: 3.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/08/2017] [Accepted: 03/27/2017] [Indexed: 12/24/2022] Open
Abstract
Background The primary therapeutic goals in the treatment of liver injury are to support liver regeneration or bridge the gap to liver transplantation (LT). Molecular adsorbent recirculating system (MARS) therapy has shown beneficial effects for specific symptoms of liver failure; however, general survival advantages have not yet been demonstrated. Aim We studied the effects of MARS therapy compared to standard medical treatment (SMT) in two patient cohorts: in patients with an acute liver injury and in those with graft dysfunction (GD). Methods We report on our experience over a 6.5-year period with 73 patients treated with SMT or with SMT and MARS (MARS group). In total, 53 patients suffered from acute liver injury in their native liver without a preexisting liver disease (SMT: n = 31, MARS: n = 22), and 20 patients showed a severe GD after LT (SMT: n = 10, MARS: n = 10). Results The entire cohort was predominantly characterized by hemodynamically and respiratorily stable patients with a low hepatic encephalopathy (HE) grade and a model of end-stage liver disease (MELD) score of 20.57 (MARS) or 22.51 (SMT, p = 0.555). Within the MARS group, the median number of extracorporeal therapy sessions was four (range = 3–5 sessions). Independent of the underlying etiology, MARS improved the patients’ bilirubin values in the short term compared to SMT alone. In patients with acute liver injury, this response was sustained even after the end of MARS therapy. By contrast, the majority of patients with GD and an initial response to MARS therapy experienced worsened hyperbilirubinemia. No differences in 28-day mortality were observed with respect to acute liver injury (MARS 5.3% (95% CI: 0–15.3); SMT 3.3% (95% CI: 0–9.8), p = 0.754) or GD (MARS 20.0% (95% CI: 0–44.7), SMT 11.1% (95% CI: 0–31.7), p = 0.478). Conclusions Although it did not improve 28-day mortality, MARS therapy improved the short-term response in patients with acute liver injury as well as in those with GD. In cases of acute hepatic injury, the use of MARS therapy resulted in the sustained stabilization of liver function and improved liver regeneration. A short-term response to MARS may predict the future course of the disease.

Abstract
BACKGROUND & AIMS Although survival times have increased for patients with cirrhosis, hepatic encephalopathy (HE) remains a major complication and its relative contribution toward mortality in North America is unclear. We investigated whether HE is associated with mortality independent of extrahepatic organ failures (EHOFs). METHODS We collected data from the North American Consortium for Study of End-stage Liver Disease database of hospitalized patients with cirrhosis at tertiary-care centers. EHOFs were defined as need for ventilation (respiratory failure), dialysis (renal failure), or shock (circulatory failure). We analyzed in-hospital and 30-day mortality for patients with varying HE grades and EHOF using adjusted models. RESULTS We analyzed data from 1560 patients, 516 with HE (371 grade 1-2 and 145 grade 3-4). Patients with maximum HE grade 3-4 HE during hospitalization had a higher median model for end-stage liver disease (MELD) score (22) than patients with HE grade 1-2 (MELD score, 19) or no HE (MELD score, 18) (P < .0001). Thirty-day mortality for patients with HE grade 3-4 was significantly higher (38%) than for patients with HE grade 1-2 (8%) or no HE (7%). A total of 107 patients had 2 or more EHOFs, with or without HE; 151 had 1 EHOF and 1302 had no organ failure. Unadjusted mortality was highest for patients with HE of grade 3-4 with 2 EHOFs (n = 44). On regression analysis, HE severity was significantly associated with in-hospital and 30-day mortality, independent of any EHOF, white blood cell count, systemic inflammatory response syndrome, or MELD score (odds ratio, 3.3; P < .0001). CONCLUSIONS In an analysis of more than 1500 patients hospitalized for cirrhosis, HE of grade 3 or 4 was associated with higher in-hospital and 30-day mortality, independently of failure of other organs.

Abstract
Albumin, a negatively charged globular protein encoded on chromosome 4, is one of the most abundant proteins in the plasma and accounts for approximately 75% of plasma oncotic pressure. The role of albumin in the management of various disease states has shown to be beneficial historically. Low serum albumin is a predictor of mortality and poor outcomes. In cirrhotics undergoing paracentesis, albumin infusion prevents rapid re-accumulation of ascitic fluid while simultaneously decreasing the risk of post-paracentesis related circulatory dysfunction. Additionally, albumin is utilized in patients with hepatorenal syndrome (HRS) and spontaneous bacterial peritonitis (SBP). Overall, albumin appears to be an effective pharmacological agent in the management of cirrhosis and its complications.

Abstract
Acute-on-chronic liver failure (ACLF) is a syndrome characterised by acute decompensation of chronic liver disease associated with organ failures and high short-term mortality. Alcohol and chronic viral hepatitis are the most common underlying liver diseases. Up to 40%-50% of the cases of ACLF have no identifiable trigger; in the remaining patients, sepsis, active alcoholism and relapse of chronic viral hepatitis are the most common reported precipitating factors. An excessive systemic inflammatory response seems to play a crucial role in the development of ACLF. Using a liver-adapted sequential organ assessment failure score, it is possible to triage and prognosticate the outcome of patients with ACLF. The course of ACLF is dynamic and changes over the course of hospital admission. Most of the patients will have a clear prognosis between day 3 and 7 of hospital admission and clinical decisions such as evaluation for liver transplant or discussion over goals of care could be tailored using clinical scores. Bioartificial liver support systems, granulocyte-colony stimulating factors or stem-cell transplant are in the horizon of medical care of this patient population; however, data are too premature to implement them as standard of care.

Abstract
BACKGROUND Liver failure (LF) is associated with prolonged hospital stay, increased cost and substantial mortality. Due to the limited number of donor organs, extracorporeal liver support is suggested as an appealing concept to "bridge to transplant" or to avoid transplant in case of recovery. ADVanced Organ Support (ADVOS) is a new type of albumin dialysis, that provides rapid regeneration of toxin-binding albumin by two purification circuits altering the binding capacities of albumin by biochemical (changing of pH) and physical (changing of temperature) modulation of the dialysate. It was the aim of this study to evaluate feasibility, efficacy and safety of ADVOS in the first 14 patients ever treated with this procedure. METHODS Patients included suffered from acute on chronic LF (n = 9) or "secondary" LF (n = 5) which resulted from non-hepatic diseases such as sepsis. The primary endpoint was the change of serum bilirubin, creatinine and serum BUN levels before and after the first treatment with ADVOS. The Wilcoxon Signed Rank test for paired samples was used to analyze the data. RESULTS A total of 239 treatments (1 up to 101 per patient) were performed in 14 patients (6 female, 8 male). Mean age 54 ± 13; MELD-score 34 ± 7; CLIF-SOFA 15 ± 3. Serum bilirubin levels were significantly decreased by 32% during the first session (26.0 ± 15.4 vs. 17.7 ± 10.5 mg/dl; p = 0.001). Similarly, serum creatinine (2.2 ± 0.8 vs. 1.6 ± 0.7 mg/dl; p = 0.005) and serum BUN (49.4 ± 23.3 vs. 31.1 ± 19.7 mg/dl; p = 0.003), were significantly lowered by 27% and 37%, respectively. None of the treatment sessions had to be interrupted due to side effects related to the procedure. CONCLUSION ADVOS efficiently eliminates water- and protein-bound toxins in humans with LF. ADVOS is feasible in patients with advanced LF which is emphasized by a total number of more than 100 treatment sessions in one single patient.

Abstract
Das akut-auf-chronische Leberversagen („acute-on-chronic liver failure“, ACLF) ist ein emergentes Krankheitssyndrom, das durch einen oder mehrere akute Trigger bei vorgeschädigter Leber ausgelöst wird und vom progressiven hepatalen und nichthepatalen Organversagen, einem gravierenden Risiko infektiöser Komplikationen sowie hoher kurzfristiger Letalität gekennzeichnet ist. Wenngleich pathophysiologisch noch weitgehend unverstanden erfordert das ACLF frühzeitige diagnostische und therapeutische Maßnahmen, die sich auf zugrunde liegende Ursachen sowie das Verhindern von Komplikationen richten, um die Prognose betroffener Patienten zu verbessern.

Abstract
A clinical science workshop was held at the ISHEN meeting in London on Friday 11th September 2014 with the aim of thrashing out how we might translate what we know about the central role of the gut-liver-brain axis into targets which we can use in the treatment of hepatic encephalopathy (HE). This review summarises the integral role that inter-organ ammonia metabolism plays in the pathogenesis of HE with specific discussion of the roles that the small and large intestine, liver, brain, kidney and muscle assume in ammonia and glutamine metabolism. Most recently, the salivary and gut microbiome have been shown to underpin the pathophysiological changes which culminate in HE and patients with advanced cirrhosis present with enteric dysbiosis with small bowel bacterial overgrowth and translocation of bacteria and their products across a leaky gut epithelial barrier. Resident macrophages within the liver are able to sense bacterial degradation products initiating a pro-inflammatory response within the hepatic parenchyma and release of cytokines such as tumour necrosis factor alpha (TNF-α) and interleukin-8 into the systemic circulation. The endotoxemia and systemic inflammatory response that are generated predispose both to the development of infection as well as the manifestation of covert and overt HE. Co-morbidities such as diabetes and insulin resistance, which commonly accompany cirrhosis, may promote slow gut transit, promote bacterial overgrowth and increase glutaminase activity and may need to be acknowledged in HE risk stratification assessments and therapeutic regimens. Therapies are discussed which target ammonia production, utilisation or excretion at an individual organ level, or which reduce systemic inflammation and endotoxemia which are known to exacerbate the cerebral effects of ammonia in HE. The ideal therapeutic strategy would be to use an agent that can reduce hyperammonemia and reduce systemic inflammation or perhaps to adopt a combination of therapies that can address both.

At the recent ISHEN ('International Symposium of Hepatic Encephalopathy & Nitrogen Metabolism') conference in London, a whole session was dedicated to our increasing awareness of the importance of inflammation in the brain - termed 'neuroinflammation', in the development of Hepatic Encephalopathy (HE) - the neurological manifestations of advanced liver disease. In this review our ISHEN speakers further discuss the content of their sessional presentations and more broadly we discuss our understanding of the role of neuroinflammation in HE pathogenesis.

Abstract
BACKGROUND In children acute liver failure is a rare but life-threatening condition from which two-thirds do not recover with supportive therapy. Treatment is limited by the availability of liver transplants. Molecular adsorbent recirculating system (MARS) dialysis is a bridge to transplantation that enhances the chances of survival during the waiting period for a transplant, although it cannot improve survival. Open albumin dialysis (OPAL) is a new mode of albumin dialysis developed to further improve dialysis efficiency. CASE DIAGNOSIS/TREATMENT We report a paediatric case of acute-on-chronic liver failure and compare the two modes of albumin dialysis, namely, the MARS and OPAL, used to treat this patient's cholestatic pruritus. Removal of total and direct bilirubin, ammonia and bile acids were measured by serial blood tests. There was an increased removal of bile acids with the OPAL mode, whereas the removal of total and direct bilirubin and ammonia was similar in both modes. The patient reported better improvement in pruritus following OPAL compared to dialysis with the MARS. CONCLUSION OPAL may offer a better solution than the MARS in the treatment of refractory pruritus in liver failure.

Overt hepatic encephalopathy: development of a novel clinician reported outcome tool and electronic caregiver diary. Metab Brain Dis 2016; 31:1081-93.

Abstract
Clinical management and clinical trials of patients with overt hepatic encephalopathy (OHE) are compromised by lack of standardized and reproducible tools for its clinical diagnosis or for caregiver (CG) identification of OHE manifestations which merit medical evaluation. Using an iterative Delphi method, Steering Committee and international hepatologist panel, the West Haven (WH) scale was modified to develop and operationalize a clinician tool for OHE identification and grading (HE Grading Instrument, HEGI™). Major diagnostic criteria included disorientation to time, place, and person, asterixis, lethargy, and coma. Minimum HEGI requirements for OHE diagnosis included: (1) disorientation, or (2) presence of both lethargy and asterixis, or (3) coma. Inter- and intra-rater HEGI reproducibility were 97 % and 98 %, respectively. When applied to a phase II clinical trial population of 178 patients with 388 OHE episodes, HEGI demonstrated excellent concordance with investigator judgement. Additionally, a multi-stage study was conducted to develop a daily CG e-diary, based on OHE manifestations recognizable by CG including speech difficulties, unusual behavior, forgetfulness, confusion, disorientation and level of consciousness. The e-diary was designed for use on smart phone, laptop or desktop, utilized branching logic and skip patterns, incorporated automatic daily completion reminders and real time alerts to clinical sites to facilitate daily standardized CG input and was found to be user friendly and understandable. The HEGI and e-diary, which were developed using methodology accepted by regulatory authorities, are designed to facilitate the design and interpretation of clinical trials for OHE and improve outcomes for OHE patients in clinical practice.
