Abstract
Hepatic encephalopathy (HE) is a consequence of liver disease and often diagnosed via psychometric testing. With inpatients, the Montreal Cognitive Assessment (MoCA) may be used as part of cognitive screening for transplant candidacy. However, the MoCA was developed to detect mild cognitive impairment in aging populations and its psychometric properties in inpatients with liver disease have not been determined. Retrospective chart review identified inpatient liver transplant candidates who were administered a MoCA as part of their neuropsychological screening and had either no cognitive dysfunction or a diagnosis of HE made by a neuropsychologist (n = 57, mean age = 48.8 ± 12.6 years). Psychometric analyses were conducted and regression analysis was performed to determine the predictive value of different variables on total MoCA scores. Internal consistency of MoCA domain scores was good (α = 0.80). Significant inverse relationships were found with Trail Making Test, Parts A and B (r's = -0.43 and -0.71, respectively). A cutoff score of 24 or below had the best sensitivity (0.72) and specificity (0.77) for identifying those with a diagnosis of HE. Increasing age and the presence of altered mental status were the strongest predictors of lower MoCA scores (both p's < 0.05, ηp2 = 0.10-0.14). The MoCA is appropriate to use with inpatient liver transplant candidates, with a cutoff of 24 or below to detect abnormal cognition. In addition to the clinical interview and other neuropsychological tests (including, but not limited to, the Trail Making Test, Parts A and B), low MoCA scores can help determine the presence of HE.

Risk Factors for Hepatic Encephalopathy in Hepatocellular Carcinoma After Sorafenib or Lenvatinib Treatment: A Real-World Study. Drug Des Devel Ther 2022; 16:4429-4437. [PMID: 36597443 PMCID: PMC9805705 DOI: 10.2147/dddt.s386829] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/23/2022] [Accepted: 11/16/2022] [Indexed: 12/29/2022] Open
Abstract
Purpose This study aimed to investigate the incidence rate and risk factors for hepatic encephalopathy (HE) among unresectable hepatocellular carcinoma (uHCC) patients with liver cirrhosis who received sorafenib or lenvatinib treatment. Patients and Methods uHCC patients with cirrhosis who received first-line sorafenib or lenvatinib treatment between September 2014 and February 2021 were continually reviewed in our single-center retrospective study. The Hepatic Encephalopathy Scoring Algorithm was used to evaluate the occurrence and grade of HE during treatment, and logistic regression models were used to further explore the risk factors for HE. Results A total of 454 eligible patients were enrolled in our study, with 214 and 240 patients in the sorafenib and lenvatinib groups, respectively. At time of data cut-off (2021-12), the incidence of HE in sorafenib group (4.2%, 95% CI:2-7%) was significantly lower than that in lenvatinib group (11.3%,95% CI:7-15%) (p = 0.006), with alcoholic cirrhosis [OR: 5.857 (95% CI: 1.519-22.591)], Child-Pugh >7 [OR: 3.023 (95% CI: 1.135-8.053)], blood ammonia ≥38.65 μmol/L [OR: 4.693 (95% CI: 1.782-12.358)], total bile acid ≥29.5 μmol/L [OR: 11.047 (95% CI: 4.414-27.650)] and duration of treatment ≥5.6 months [OR: 4.350 (95% CI: 1.701-11.126)] to be risk factors for the occurrence of HE during first-line systemic therapy. Conclusion In our study, for off-label uHCC patients (Child-Pugh >7) with alcoholic cirrhosis, hyperammonemia, hypercholesterolemia, and estimated longer duration of treatment, the application of lenvatinib has to be cautious, which needs to be confirmed in future clinical trials.

Abstract
Patients with liver disease often have alteration of neurological status which requires admission to an intensive care unit. Patients with acute liver failure (ALF), acute-on-chronic liver failure (ACLF) and rarely cirrhosis are at risk of cerebral edema. These patients require prompt assessment of neurological status including assessment of intra-cranial pressure (ICP) and monitoring metabolic parameters like arterial/venous ammonia levels, serum creatinine and serum electrolytes so that timely specific therapy for raised ICP can be instituted to prevent permanent neurological dysfunction. The overall aims of neuromonitoring and sedation protocols in a liver intensive care unit are to identify the level of multifactorial metabolic encephalopathy, individualize sedation and analgesia requirements for patients on mechanical ventilation, institute specific therapy to correct the neurological insult in ALF and ACLF, provide clear physiological data for guided therapy of drugs like muscle relaxants, antiepileptics, and cerebral edema reducing agents, and assist with overall prognostication. In this review article we will outline the clinical scenarios related to liver disease requiring intensive care and neuromonitoring, current techniques of neurological assessment, sedation protocols and point of care tests which enable the treating physician and intensivist guide therapy for raised ICP.

Abstract
Hepatic encephalopathy (HE) is a very prevalent condition in patients with advanced liver disease and has a high recurrence rate. The pathophysiology has a multifactorial origin where hyperammonaemia and inflammation become particularly relevant. There are no HE-specific diagnostic tests, and diagnosis is usually made by taking into account the presence of suggestive and compatible clinical symptoms, the existence of a predisposing liver condition and ruling out other causes with similar clinical manifestations. Once the diagnosis of HE is established, it is essential to carry out an adequate classification based on the underlying liver disease, the intensity of clinical manifestations, the temporal course of the disease and the presence or absence of precipitating factors. Treatment should be aimed at decreasing the duration, intensity and consequences of episodes, preventing recurrence and limiting the impact of the disease in patients and their relatives.

Combined PEG3350 Plus Lactulose Results in Early Resolution of Hepatic Encephalopathy and Improved 28-Day Survival in Acute-on-Chronic Liver Failure. J Clin Gastroenterol 2022; 56:e11-e19. [PMID: 33060437 DOI: 10.1097/mcg.0000000000001450] [Citation(s) in RCA: 12] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/17/2020] [Accepted: 09/12/2020] [Indexed: 12/30/2022]
Abstract
BACKGROUND AND AIMS Acute-on-chronic liver failure (ACLF) is associated with high short-term mortality in those with hepatic encephalopathy (HE). Polyethylene glycol (PEG) 3350 electrolyte solution can ensure rapid gut catharsis, which may resolve HE more effectively than lactulose. In this open-label-randomized trial, we compared PEG+lactulose versus lactulose alone in ACLF with HE grade ≥2 for efficacy and outcome. PATIENTS AND METHODS Patients were randomized to receive PEG (2 L q12 h) followed by lactulose (30 mL q8 h) or standard medical treatment [SMT, lactulose (titrated 30 mL q8 h)]. Endpoints were HE grade improvement at 24 hours, 48 hours, and 7 days using hepatic encephalopathy scoring algorithm (HESA), ammonia reduction, HE resolution, and survival benefit. RESULTS Of 60 patients, 29 were randomized to PEG+lactulose arm and 31 to SMT. In the PEG arm, early reduction in HESA score was noted in more persons [18 (62.1%) vs. 10 (32.2%); P=0.021] with a shorter median time to HE resolution [4.5 (3 to 9) d vs. 9 (8 to 11) d; P=0.023]. On multivariate analysis, age [hazard ratio (HR),1.06 (1.00 to 1.13); P=0.03], HESA score [HR, 6.01 (1.27 to 28.5); P=0.024], and model for end-stage liver disease [HR, 1.26 (1.01 to 1.53); P=0.022] were predictors of mortality at 28 days. Ammonia level or reduction did not correlate with HE grades. Adverse events included excessive diarrhea (20.6% vs. 9.6%) in the PEG and SMT arms, albeit without dyselectrolytemia or worsened renal function. In the PEG versus SMT arm, survival at 28 days were 93.1% versus 67.7% (P=0.010) and at 90 days was 68.9% versus 48.3% (P=0.940), respectively, with fewer persons relapsing with HE in the PEG arm. CONCLUSIONS PEG resulted in early and sustained HE resolution with improved short-term survival making, it a suitable and safe drug in patients with acute HE in ACLF.

Abstract
Hepatic encephalopathy (HE) is a brain dysfunction caused by liver insufficiency and/or portosystemic shunting. HE manifests as a spectrum of neurological or psychiatric abnormalities. Diagnosis of overt HE (OHE) is based on the typical clinical manifestation, but covert HE (CHE) has only very subtle clinical signs and minimal HE (MHE) is detected only by specialized time-consuming psychometric tests, for which there is still no universally accepted gold standard. Significant progress has been made in artificial intelligence and its application to medicine. In this review, we introduce how artificial intelligence has been used to diagnose minimal hepatic encephalopathy thus far, and we discuss its further potential in analyzing speech and handwriting data, which are probably the most accessible data for evaluating the cognitive state of the patient.

Abstract
Hepatic encephalopathy (HE) is an important and potentially life threatening complication in alcoholic patients with decompensated liver function that develop even as they continue drinking. Delirium tremens, on the other hand, is an acute condition resulting from alcohol abstinence in a person dependent on alcohol, making it a life threatening diagnosis that requires intensive care and successful management of the withdrawal. Often in medical wards, these two conditions are mistaken and so is the management plan confused with each other. Making the right diagnosis early on during the hospital course is extremely important in these critical conditions so as to make an appropriate schedule for treatment and a better outcome for the same. A case series of patients who presented with a diagnostic dilemma is reported. Clinical examinations, diagnostic tools to measure the levels of ammonia and liver function tests and hemogram, West Haven criteria and Child-Pugh grading, and clinical scales of these patients are reported. Increased levels of ammonia were present in all the cases. The subtle similarities in the presentation of the two conditions often make it confusing for the clinician to distinguish between them. Using a simple test of measuring ammonia levels in the blood helps in such situations. The detection of raised levels of ammonia in cases of chronic liver disease helps in not just the diagnosis but also is an important prognostic indicator for development of HE.

Abstract
BACKGROUND AND AIMS The efficacy and safety of albumin infusion for treatment and prevention of overt hepatic encephalopathy (OHE) among cirrhosis patients remained controversial. We performed a systematic review and meta-analysis to evaluate the benefit of albumin infusion for the treatment and prevention of OHE. METHODS We performed a systematic search of 4 electronic databases up to 31st January 2021. The primary outcome was the resolution of OHE. Secondary outcomes were inpatient mortality and albumin-associated adverse events. We assessed the pooled odds' risk, pooled mean differences, 95% confidence interval and heterogeneity using Review Manager Version 5.3. RESULTS A total of 12 studies (2,087 subjects) were identified. Among cirrhosis patients with OHE, albumin infusion was associated with a lower pooled risk of OHE (OR=0.43, 95%CI: 0.27, 0.68; I2=0%). Among patients without baseline OHE, albumin infusion was associated with a lower pooled risk of developing OHE (OR=0.53, 95%CI: 0.32, 0.86; I2=62%). Albumin infusion was associated with a lower pooled risk of inpatient mortality (OR=0.36, 95%CI: 0.21, 0.60; I2=0%). CONCLUSION Well-powered randomized trials are required to confirm the benefits of albumin infusion for the prevention and treatment of overt hepatic encephalopathy among decompensated cirrhosis patients.

Abstract
Queries of electronic health record (EHR) data repositories allow for automated data collection. These techniques have not been used in hepatology due to the inability to capture hepatic encephalopathy (HE) grades, which are inputs for acute-on-chronic liver failure (ACLF) models. Here, we describe a methodology to use EHR data to calculate rolling ACLF scores. We examined 239 patient admissions with end-stage liver disease from July 2014 to June 2019. We mapped EHR flowsheet data to determine HE grades and calculated two longitudinally updated ACLF scores. We validated HE grades and ACLF diagnoses by chart review and calculated sensitivity, specificity, and Cohen's kappa. Of 239 patient admissions analyzed, 37% were women, 46% were non-Hispanic white, median age was 60 years, and the median Model for End-Stage Liver Disease-Na score at admission was 25. Of the 239, 7% were diagnosed with ACLF as defined by the North American Consortium for the Study of End-Stage Liver Disease (NACSELD) diagnostic criteria at admission, 27% during the hospitalization, and 9% at discharge. Forty percent were diagnosed with ACLF by the European Association for the Study of the Liver- Chronic Liver Failure Consortium (CLIF-C) diagnostic criteria at admission, 51% during the hospitalization, and 34% at discharge. From the chart review of 51 admissions, we found sensitivities and specificities for any HE (grades 1-4) were 92%-97% and 76%-95%, respectively; for severe HE (grades 3-4), sensitivities and specificities were 100% and 78%-98%, respectively. Cohen's kappa between flowsheet and chart review of HE grades ranged from 0.55 to 0.72. Sensitivities and specificities for NACSELD-ACLF diagnoses were 75%-100% and 96%-100%, respectively; for CLIF-C-ACLF diagnoses, these were 91%-100% and 96-100%, respectively. We generated approximately 28 unique ACLF scores per patient per admission day. Conclusion: We developed an informatics-based methodology to calculate longitudinally updated ACLF scores. This opens new analytic potentials, such as big data methods, to develop electronic phenotypes for patients with ACLF.

Abstract
Hepatic encephalopathy (HE) is a frequent and serious complication of both chronic liver disease and acute liver failure. HE manifests as a wide spectrum of neuropsychiatric abnormalities, from subclinical changes (mild cognitive impairment) to marked disorientation, confusion and coma. The clinical and economic burden of HE is considerable, and it contributes greatly to impaired quality of life, morbidity and mortality. This review will critically discuss the latest classification of HE, as well as the pathogenesis and pathophysiological pathways underlying the neurological decline in patients with end-stage liver disease. In addition, management strategies, diagnostic approaches, currently available therapeutic options and novel treatment strategies are discussed.

OBJECTIVE The most appropriate medication regimen to mitigate the consequences hepatic encephalopathy remains inconclusive. This review seeks to serve as a reference for clinicians to help guide therapy decisions with regard to hepatic encephalopathy. METHODS A comprehensive literature review between August 2018 and April 2019 was accomplished with the assistance of a medical librarian. Sources of literature review include PubMed, MEDLINE, SCOPUS, ProQuest Central, CINAHL, and ProQuest Dissertations. The authors selected randomized clinical and double-blind cross-over trials evaluating probiotics, zinc, polyethylene glycol, rifaximin, and flumazenil. Sixteen clinical trials are discussed in this review. Pertinent safety, efficacy, and statistical and clinical outcomes are summarized by the authors. CONCLUSIONS The most appropriate regimen to mitigate the consequences of hepatic encephalopathy remains elusive; however, the agents discussed within this review offer alternative options for patients unresponsive to or intolerant of traditional lactulose therapy. This review seeks to serve as a repository for relevant clinical trials, and as a reference for clinicians to help guide therapy decisions.

Abstract
INTRODUCTION AND AIM Hepatic encephalopathy (HE) is a frequent complication of cirrhosis, but the clinical and prognostic significance of the progression of mental status in hospitalised cirrhotics is unknown. We aimed to investigate the prognostic significance of serial evaluation of HE in patients hospitalised for acute decompensation (AD) of cirrhosis. MATERIALS AND METHODS Patients (n=293) were evaluated for HE (West-Haven criteria) at admission and at day-3 and classified in two groups: (1) Absent or improved HE: HE absent at admission and at day-3, or any improvement at day-3; (2) Unfavourable progression: Development of HE or HE present at admission and stable/worse at day-3. RESULTS Unfavourable progression of HE was observed in 31% of patients and it was independently associated with previous HE, Child-Pugh C and acute-on-chronic liver failure (ACLF). MELD score and unfavourable progression of HE were independently associated with 90-day mortality. The 90-day Kaplan-Meier survival probability was 91% in patients with MELD<18 and absent or improved HE and only 31% in subjects with both MELD≥18 and unfavourable progression of HE. Unfavourable progression of HE was also related to lower survival in patients with or without ACLF. Worsening of GCS at day-3 was observed in 11% of the sample and was related with significantly high mortality (69% vs. 27%, P<0.001). CONCLUSION Among cirrhotics hospitalised for AD, unfavourable progression of HE was associated with high short-term mortality and therefore can be used for prognostication and to individualise clinical care.

Abstract
PURPOSE OF REVIEW Liver transplantation (LT) remains the only way to cure patients with severe liver diseases. Important questions about neurological sequelae and quality of life after LT have emerged. In this review, we discuss the neurocognitive changes associated with LT and we conclude with recommendations in this regard for patients, caregivers, and physicians. RECENT FINDINGS Compared with other solid organ recipients, LT patients tend to have a higher incidence (up to 30%) of neurological complications post-LT. Even in absence of previous episodes of hepatic encephalopathy (HE), some patients display new onset of neurological symptoms post-LT, raising the concern about the role of other factors that may have a direct impact on cognitive function. SUMMARY Different mechanisms have been postulated to explain these postoperative neurological symptoms. They include sequelae of HE, persistent impairment of cognitive function due to cirrhosis, or postoperative decompensation of an unknown or undiagnosed neurodegenerative disorder.

Abstract
PURPOSE To investigate the role of early overt hepatic encephalopathy (OHE) as a clinical marker of prognosis in cirrhosis with a transjugular intrahepatic portosystemic shunt (TIPS) and to assess the relationship between recurrence of OHE and survival after TIPS. METHODS From January 2012 to December 2013, a retrospective study of consecutive patients with cirrhosis and a TIPS was performed at a single institution. A total of 304 patients (196 males; mean age, 52 years) were enrolled during the study period. The mean Model for End-Stage Liver Disease (MELD) score was 11.6. Time-dependent Cox regression was applied to estimate the predictive ability of early OHE (within 3 months after TIPS) and the effect of its frequency on survival. RESULTS During a median follow-up of 28.3 months, 115 patients experienced OHE after the TIPS procedure; of these, 54 had at least 2 OHE episodes. Long-term survival worsened in patients with early OHE (hazard ratio [HR] = 2.75; 95% confidence interval [CI]: 1.75-4.32; P < .001). When early OHE was further divided into early-recurrent and single OHE, death was more common in patients with early-recurrent OHE (P < .001) than in patients with early-single OHE (P = .24). After adjustment by MELD score, ascites, serum albumin, indication for TIPS, and age, patients with early-recurrent OHE had a lower probability of survival (HR = 2.91; 95% CI: 1.04-4.89; P < .001). Furthermore, landmark and propensity score analyses confirmed the predictive value of early-recurrent OHE. CONCLUSIONS Early recurrence of OHE was associated with an increased risk of mortality for patients with cirrhosis who underwent TIPS.

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
Cirrhotic patients with infection are prone to develop sepsis or even septic shock rendering poorer prognosis. However, few methods are available to predict the prognosis of cirrhotic patients with infection although there are some scoring systems can be used to predict general patients with cirrhosis. Therefore, we aimed to explore the predictive value of scoring systems in determining the outcome of critically ill cirrhotic patients with suspected infection.This was a retrospective cohort study based on a single-center database. The prognostic accuracy of the systemic inflammatory response syndrome (SIRS) criteria, quick Sequential Organ Failure Assessment (qSOFA), chronic liver failure (CLIF)-SOFA, quick CLIF-SOFA (qCLIF-SOFA), CLIF-consortium organ failure (CLIF-C OF), Model for End-Stage Liver Disease (MELD), and Simplified Acute Physiology Score (SAPS) II were compared by using area under the receiver operating characteristic (AUROC) curve and net benefit with decision curve analysis. The primary endpoint was in-hospital mortality while the secondary endpoints were duration of hospital and intensive care unit (ICU) stay and ICU mortality.A total of 1438 cirrhotic patients with suspected infection were included in the study. Nearly half the patients (50.2%) were admitted to the ICU due to hepatic encephalopathy and the overall in-hospital mortality was 32.0%. Hospital and ICU mortality increased as the score of each scoring system increased (P < .05 for all trends). The AUROC of CLIF-SOFA (AUROC, 0.742; 95% confidence interval, CI, 0.714-0.770), CLIF-C OF (AUROC, 0.741; 95% CI, 0.713-0.769), and SAPS II (AUROC, 0.759; 95% CI, 0.733-0.786) were significantly higher than SIRS criteria (AUROC, 0.618; 95% CI, 0.590-0.647), qSOFA (AUROC, 0.612; 95% CI, 0.584-0.640), MELD (AUROC, 0.632; 95% CI, 0.601-0.662), or qCLIF-SOFA (AUROC, 0.680; 95% CI, 0.650-0.710) (P < .05 for all). In the decision curve analysis, the net benefit of implementing CLIF-SOFA and CLIF-C OF to predict the prognosis of cirrhotic patients with suspected infection were higher compared with SIRS, qSOFA, MELD, or qCLIF-SOFA.CLIF-SOFA and CLIF-C OF scores, as well as SAPS II were better tools than SIRS, qSOFA, MELD, or qCLIF-SOFA to evaluate the prognosis of critically ill cirrhotic patients with suspected infection.

Abstract
BACKGROUND & AIMS Infections are life-threatening to patients with acute decompensation and acute-on-chronic liver failure (AD/ACLF). Patients with AD/ACLF have prostaglandin E2-mediated immune suppression, which can be reversed by administration of albumin; infusion of 20% human albumin solution (HAS) might improve outcomes of infections. We performed a feasibility study to determine optimal trial design, assess safety, and validate laboratory assessments of immune function to inform design of a phase 3 trial. METHODS We performed a prospective multicenter, single-arm, open-label trial of 79 patients with AD/ACLF and levels of albumin lower than 30 g/L, seen at 10 hospitals in the United Kingdom from May through December 2015. Patients were given daily infusions of 20% HAS, based on serum levels, for 14 days or until discharge from the hospital. Rates of infection, organ dysfunction, and in-hospital mortality were recorded. The primary end point was daily serum albumin level during the treatment period. Success would be demonstrated if 60% achieved and maintained serum albumin levels at or above 30 g/L on at least one third of days with recorded levels. RESULTS The patients' mean model for end-stage disease score was 20.9 ± 6.6. The primary end point (albumin ≥30 g/L on at least one third of days recorded) was achieved by 68 of the 79 patients; 75% of administrations were in accordance with suggested dosing regimen. Mean treatment duration was 10.3 days (104 ± 678 mL administered). There were 8 deaths and 13 serious adverse events, considered by the independent data-monitoring committee to be consistent with those expected. Twelve of 13 patients that developed either respiratory or cardiovascular dysfunction (based on ward-based clinical definitions) as their only organ dysfunction were alive at 30 days compared with 1 of 3 that developed renal dysfunction. Only 1 case of brain dysfunction was recorded. CONCLUSIONS In a feasibility trial, we found that administration of HAS increased serum levels of albumin in patients with AD/ACLF. The dosing regimen was acceptable at multiple sites and deemed safe by an independent data-monitoring committee. We also developed a robust system to record infections. The poor prognosis for patients with renal dysfunction was confirmed. However, patients with cardiovascular or respiratory dysfunction had good outcomes, which is counterintuitive. Severe encephalopathy appeared substantially under-reported, indicating that ward-based assessment of these parameters cannot be recorded with sufficient accuracy for use as a primary outcome in phase 3 trials. Trial registration no: EudraCT 2014-002300-24 and ISRCTN14174793.

Abstract
Over half a million Americans are affected by cirrhosis, the cause of end-stage liver disease (ESLD). Little is known about how symptom burden changes over time in adults with ESLD and their informal caregivers, which limits our ability to develop palliative care interventions that can optimize symptom management and quality of life in different patient-caregiver dyads. The purpose of this article is to describe the background and design of a prospective, longitudinal descriptive study, "Symptom Burden in End-Stage Liver Disease Patient-Caregiver Dyads," which is currently in progress. The study is designed to (i) identify trajectories of change in physical and psychological symptom burden in adults with ESLD; (ii) identify trajectories of change in physical and psychological symptom burden in caregivers of adults with ESLD; and (iii) determine predictors of types of patient-caregiver dyads that would benefit from tailored palliative care interventions. We aim for a final sample of 200 patients and 200 caregivers who will be followed over 12 months. Integrated multilevel and latent growth mixture modeling will be used to identify trajectories of change in symptom burden, linking those changes to clinical events, and quality of life outcomes and characterizing types of patient-caregiver dyads based on patient-, caregiver-, and dyad-level factors. Challenges we have encountered include unexpected attrition of study participants, participants not returning their baseline questionnaires, and hiring and training of research staff. The study will lay the foundation for future research and innovation in ESLD, end-of-life and palliative care, and caregiving.

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.

Polyethylene Glycol and Lactulose versus Lactulose Alone in the Treatment of Hepatic Encephalopathy in Patients with Cirrhosis: A Non-Inferiority Randomized Controlled Trial. Middle East J Dig Dis 2017; 9:12-19. [PMID: 28316761 PMCID: PMC5308129 DOI: 10.15171/mejdd.2016.46] [Citation(s) in RCA: 26] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Indexed: 12/11/2022] Open
Abstract
BACKGROUND In this clinical trial, polyethylene glycol (PEG) solution was compared with lactulose in the treatment of hepatic encephalopathy in patients with cirrhosis. METHODS This randomized controlled trial was performed on 40 patients in two groups. The patients in the lactulose group received either 20-30 grams of lactulose orally or by a nasogastric tube, or 200 grams of lactulose enema by a rectal tube. The patients in the PEG-lactulose group received the same amount of oral or rectal lactulose, plus 280 grams of PEG in 4 liters of water orally as a single dose in 30-120 minutes. Serial physical examinations, hepatic encephalopathy scoring algorithm (HESA), blood level of ammonia, and serum biochemical studies were used to evaluate the severity of hepatic encephalopathy. RESULTS In comparison with lactulose alone, PEG-lactulose could improve HESA score in 24 hours more effectively (p =0.04). Overall, PEG-lactulose regimen was associated with a decrease in length of hospital stay compared with lactulose treatment (p =0.03) but in subgroup analysis we found that PEG-lactulose regimen could only decrease the length of hospital stay in women significantly (p =0.01). CONCLUSION The use of PEG along with lactulose in comparison with lactulose alone is more effective in the treatment of hepatic encephalopathy in patients with cirrhosis and results in more rapid discharge from hospital.

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.

Abstract
BACKGROUND The practice of hospital medicine is complex, and the number of clinical publications each year continues to grow. To maintain best practice it is necessary for hospitalists to stay abreast of the literature, but difficult to accomplish due to time. The annual Society of Hospital Medicine meeting offers a plenary session on Updates in Hospital Medicine. This article is a summary of those papers presented at the meeting. METHODS We reviewed articles published between January 2014 and January 2015 in the leading medical journals, searching for papers with good methodological quality, the potential to change practice, and papers that are thought provoking. The authors collectively agreed on 14 articles. The findings, cautions, and implications are discussed for each paper. RESULTS Key findings include: a novel neprilysin inhibitor and angiotensin receptor blocker combination drug reduces mortality in patients with heart failure; the concern for acute kidney injury after venous contrast may be overstated; the Confusion Assessment Method Severity score is an important tool for prognostication in delirious patients; ramelteon shows promise for lowering incident delirium among elderly medical patients; polyethylene glycol appears effective in rapidly resolving hepatic encephalopathy; cirrhotic patients on a nonselective β-blocker have increased mortality after they develop spontaneous bacterial peritonitis; current guidelines regarding prophylaxis against venous thromboembolism (VTE) in medical inpatients likely result in non-beneficial use of medications; from a safety and efficacy perspective, direct oral anticoagulants perform quite well against conventional therapies in patients with VTE and atrial fibrillation, including in elderly populations; 2 new once-weekly antibiotics, dalbavancin and oritivancin, approved for skin and soft tissue infections, appear noninferior to vancomycin; offering family members of a patient undergoing cardiopulmonary resuscitation the opportunity to observe has durable impact on long-term psychological outcomes. CONCLUSIONS This update reviews key clinical articles published in 2014, selected by the authors for their methodological quality and potential for changing the practice of inpatient physicians. All of these articles add to the body of inpatient medical knowledge and contribute to the debate on best practices.

Abstract
BACKGROUND Recent evidence suggests that bispectral index may aid in the diagnosis of hepatic encephalopathy. We evaluated its utility to diagnose, grade and monitor clinical course of hepatic encephalopathy in patients with cirrhosis. METHODS 200 patients (70.5% males, mean age 39.5±9.1 years) with cirrhosis and 20 healthy controls were enrolled prospectively. Cirrhotic patients were divided into groups based on encephalopathy grades I-IV assessed by West Haven criteria; minimal encephalopathy was assessed by psychometric tests. Bispectral index was measured at baseline and after one week of lactulose therapy in patients with overt encephalopathy, and after 3 months in patients with minimal encephalopathy. RESULTS Bispectral index scores were significantly different in patients with different grades of encephalopathy; 79.5±4.2, 67.5±4.3, 56.4±3.5, 44.8±3.9 and 85.0±4.3 respectively for grade I, II, III, IV overt and minimal hepatic encephalopathy, but similar (92.6±3.7 vs 93.75±2.8) in cirrhotics without encephalopathy and healthy controls. Bispectral scores' cut off values for minimal and overt encephalopathy grade I, II, III, IV were 90.5 and 77.5, 70.5, 60.5, 50.5, respectively. Changes in bispectral index after treatment corresponded to cut-off scores for grades of overt and minimal hepatic encephalopathy. CONCLUSIONS Bispectral index was found to be useful in diagnosis, grading and monitoring of treatment response in cirrhotic patients with hepatic encephalopathy.

Abstract
In the intensive care unit (ICU), delirium is routinely measured with the widely-used, validated Confusion Assessment Method for the ICU (CAM-ICU), but CAM-ICU has not been studied in patients with cirrhosis. We studied a group of patients with cirrhosis to determine the relationship between delirium measured by CAM-ICU and clinical outcomes. Consecutive patients with cirrhosis admitted to the ICU from 2009 to 2012 were included in a retrospective cohort study. Patients were screened twice daily for coma and delirium during their ICU stay using the Richmond Agitation Sedation Scale (RASS) and CAM-ICU. The association between delirium/coma and mortality was determined using multiple logistic regression. RASS and CAM-ICU were also compared to a retrospective assessment of hepatic encephalopathy (HE). Of 91 patients with cirrhosis, 26 (28.6 %) developed delirium/coma. RASS/CAM-ICU had fair agreement with the HE assessment (κ 0.38). Patients with delirium/coma had numerically greater mortality in-hospital (23.1 vs. 7.7 %, p = 0.07) and at 90 days (30.8 vs. 18.5 %, p = 0.26), and they also had longer hospital length of stay (median 19.5 vs. 6 days, p < 0.001). Delirium/coma was associated with increased inpatient mortality, independent of disease severity (unadjusted OR 3.6; 95 % CI, 0.99-13.1; MELD-adjusted OR 5.4; 95 % CI, 1.3-23.8; acute physiology score-adjusted OR 2.2; 95 % CI, 0.53-8.9). Delirium/coma was also associated with longer length of stay after adjusting for disease severity. In critically ill patients with cirrhosis, delirium/coma as measured by the RASS and CAM-ICU is associated with increased mortality and hospital length of stay. For these patients, these measures provide valuable information and may be useful tools for clinical care. RASS and CAM-ICU need to be compared to HE-specific measures in future studies.

Abstract
Hepatic encephalopathy (HE) is associated with cerebral edema (CE), increased intracranial pressure (ICP), and subsequent neurologic complications; it is the most important cause of morbidity and mortality in fulminant hepatic failure. The goal of therapy should be early diagnosis and treatment of HE with measures to reduce CE. A combination of clinical examination and diagnostic modalities can aid in prompt diagnosis. ICP monitoring and transcranial Doppler help diagnose and monitor response to treatment. Transfer to a transplant center and intensive care unit admission with airway management and reduction of CE with hypertonic saline, mannitol, hypothermia, and sedation are recommended as a bridge to liver transplantation.

Abstract
Hepatic encephalopathy is a brain alteration associated to liver failure that produces cognitive impairments at long term. Neuroimaging are non-invasive methods for the study of the brain by means of spectroscopy and imaging techniques. These technologies give huge information about cerebral metabolism and water distribution to explore brain pathways involved in the pathogenesis of hepatic encephalopathy. Furthermore, new magnetic resonance implementations such as voxel-based morphometry or resting-state functional magnetic resonance imaging allow studying brain atrophy and neuronal connectivity of the cerebral network involved in the neurocognitive impairments observed in the patients. The development of magnetic resonance technology will generate handy tools for the brain study of liver failure to elucidate the time-course of the pathology and thus to obtain an early diagnosis of cerebral complications.

Abstract
Microemulsions with limited stability in mimetic gastrointestinal environments have previously demonstrated potential for the effective removal of ammonia from artificial colonic fluid. Specialized pH‑sensitive microemulsion‑based gels for the removal of colonic ammonia (MBG‑RCA), however, possess relative stability in the gastrointestinal (GI) tract of normal rats, indicating potential use in in vivo applications. An investigation of the effects of oral MBG‑RCA was conducted in order to evaluate the reduction of intestinal ammonia and the prevention of hepatic encephalopathy (HE) in rat models. Eighty rats were allocated into eight 4‑day treatment groups: The HE model (intraperitoneal injection of thioacetamide) group; the high‑, medium‑ and low‑dose MBG‑RCA therapeutic groups (15, 10 and 5 ml/kg MBG‑RCA, respectively); and the normal, blank, lactulose and acetic acid control groups, each of which received daily treatment administration. Oral MBG‑RCA effects were identified using behavioral monitoring observed by an infrared night vision supervisory control system, electroencephalograms, blood ammonia levels, intestinal ammonia levels, liver functionality and pathological observation. High‑ and medium‑dose oral administrations of MBG‑RCA significantly decreased the blood and intestinal ammonia levels (P<0.05), improved liver functionality and reduced the clinical manifestations of HE in rats. MBG‑RCA demonstrated high clearance of rat colonic ammonia while maintaining sufficient stability in the GI tract, indicating the potential for the development of new clinically relevant oral preparations for the prevention of HE. Additionally, such preparations are advantageous in that ammonia is eliminated without the production of potentially harmful metabolic byproducts.

Abstract
Little progress has been made in the pharmacological management of patients with hepatic encephalopathy, partly because it is difficult to perform clinical trials in this group of patients. A new clinical trial now suggests that polyethylene glycol is more effective than the current standard first-line therapy in these patients.

Abstract
IMPORTANCE Hepatic encephalopathy (HE) is a common cause of hospitalization in patients with cirrhosis. Pharmacologic treatment for acute (overt) HE has remained the same for decades. OBJECTIVE To compare polyethylene glycol 3350-electrolyte solution (PEG) and lactulose treatments in patients with cirrhosis admitted to the hospital for HE. We hypothesized that rapid catharsis of the gut using PEG may resolve HE more effectively than lactulose. DESIGN, SETTING, AND PARTICIPANTS The HELP (Hepatic Encephalopathy: Lactulose vs Polyethylene Glycol 3350-Electrolyte Solution) study is a randomized clinical trial in an academic tertiary hospital of 50 patients with cirrhosis (of 186 screened) admitted for HE. INTERVENTIONS Participants were block randomized to receive treatment with PEG, 4-L dose (n = 25), or standard-of-care lactulose (n = 25) during hospitalization. MAIN OUTCOMES AND MEASURES The primary end point was an improvement of 1 or more in HE grade at 24 hours, determined using the hepatic encephalopathy scoring algorithm (HESA), ranging from 0 (normal clinical and neuropsychological assessments) to 4 (coma). Secondary outcomes included time to HE resolution and overall length of stay. RESULTS A total of 25 patients were randomized to each treatment arm. Baseline clinical features at admission were similar in the groups. Thirteen of 25 patients in the standard therapy arm (52%) had an improvement of 1 or more in HESA score, thus meeting the primary outcome measure, compared with 21 of 23 evaluated patients receiving PEG (91%) (P < .01); 1 patient was discharged before final analysis and 1 refused participation. The mean (SD) HESA score at 24 hours for patients receiving standard therapy changed from 2.3 (0.9) to 1.6 (0.9) compared with a change from 2.3 (0.9) to 0.9 (1.0) for the PEG-treated groups (P = .002). The median time for HE resolution was 2 days for standard therapy and 1 day for PEG (P = .01). Adverse events were uncommon, and none was definitely study related. CONCLUSIONS AND RELEVANCE PEG led to more rapid HE resolution than standard therapy, suggesting that PEG may be superior to standard lactulose therapy in patients with cirrhosis hospitalized for acute HE. TRIAL REGISTRATION clinicaltrials.gov Identifier: NCT01283152.

Abstract
The term "hepatic encephalopathy" (HE) covers the neuropsychiatric syndrome associated with acute, chronic and acute-on-chronic liver disease (CLD). This paper deals with clinical features and diagnosis of HE in patients with liver cirrhosis and portal hypertension or porto-systemic shunts. The possible impact of concomitant disorders and the cirrhosis underlying liver disease upon brain function is described emphasizing the need of a detailed diagnostic work up of every individual case before diagnosing HE. Currently used methods for diagnosing minimal or covert hepatic encephalopathy are compared with regard to their sensitivity and specificity for diagnosing HE against the background of a multitude of concomitant disorders and diseases that could contribute to brain dysfunction.

Abstract
Hepatic encephalopathy (HE) is a serious complication of liver disease and portosystemic shunting that represents a continuum of neuropsychiatric changes and altered consciousness. It is classified as overt HE (OHE) when clinically apparent or as covert HE (CHE) in its mildest form. Progression of CHE to OHE and its impact of quality of life make its early diagnosis imperative. Several diagnostic techniques ranging from simple clinical scales to sophisticated computerized tests exist, yet diagnosis remains a challenge, due to the time, cost, and personnel involved. Psychometric tests appear promising due to their high sensitivity and low cost, but results are variable depending on age and education. The pros and cons of current diagnostic methods for OHE and CHE are reviewed, along with strategy for CHE testing.

Abstract
PURPOSE OF REVIEW Hepatic encephalopathy causes significant cognitive impairment and morbidity in patients with cirrhosis; however, hepatic encephalopathy is considered a reversible syndrome once recognized clinically. Although hepatic encephalopathy is not a single clinical entity, the pathophysiology resulting in brain dysfunction is not fully understood, although it is believed that ammonia production is an important contributing factor. The purpose of this review is to highlight studies used to test for hepatic encephalopathy and those utilizing specific new treatments. RECENT FINDINGS A 'STROOP' smartphone app has been developed to allow clinicians to test for covert hepatic encephalopathy (CHE). Lactulose therapy was effective for cirrhotic patients as primary prophylaxis to prevent overt hepatic encephalopathy (OHE) episodes. In patients without prior OHE, probiotics can be useful in preventing OHE. Lactulose, probiotics, L-ornithine-L-aspartate, and potassium-iron-phosphate-citrate have been studied in the treatment of CHE. Rifaximin was found to be safe and well tolerated in long-term maintenance of remission from OHE; however, compared to lactulose therapy in CHE, it is not cost-effective. SUMMARY Refinement in clinical management strategies for patients with cirrhosis and hepatic encephalopathy appears to continue to contribute to improved patient outcomes.

Abstract
The gut flora plays an important role in the pathogenesis of the complications of cirrhosis. Hepatic encephalopathy (HE) represents a broad continuum of neuropsychological dysfunction in patients with acute or chronic liver disease and/or porto-systemic shunting of blood flow and it manifests with progressive deterioration of the superior neurological functions. The pathophysiology of this disease is complex, as it involves overproduction and reduced metabolism of various neurotoxins, particularly ammonia. Management of HE is diversified and requires several steps: elimination of precipitating factors, removal of toxins, proper nutritional support, modulation of resident fecal flora and downregulation of systemic and gut-derived inflammation. This review will provide an overview of gut barrier function and the influence of gut-derived factors on HE, focusing on the role of gut microbiota in the pathogenesis of HE and the recent literature findings on its therapeutic manipulation.

Abstract
This purpose of this article is to promote comprehensive assessment, differential evaluation and provision of care which optimizes benefit while minimizing burden. Delirium is a debilitating neuropsychiatric complication that is highly prevalent in palliative care. It is multifactorial and may be related to infection, disease progression, metabolic state or medication toxicity. There are three proposed sub-types of delirium with the hypoactive/ hypoalert variant being most often underdiagnosed and undertreated. The inadequate management of all types of delirium is associated with increased personal and family distress, lengthier hospital stays, and escalating healthcare costs. This article reviews the assessment, diagnosis and treatment for delirium in general and hepatic encephalopathy in particular. A number of valid and reliable tools are discussed, as they assist in screening, symptom appraisal, diagnosis, and treatment planning. It is recognized that nurses are particularly well positioned to make bedside observations, to document changes over time, and to educate and support patients and their families. Searching for the etiology of delirium, developing individualized plans of care consistent with patient goals, and endorsing the benefit of consultation/referral are discussed as key roles for palliative care providers from all disciplines. New and novel therapies in the management of hepatic encephalopathy are discussed, as they expand treatment options for patients at all points along the trajectory of liver disease.

Abstract
Hepatic encephalopathy (HE) is the second most common major complication in cirrhotics and it significantly impacts quality of life. Therapeutic approaches for HE treatment and prevention mainly continue to rely on ammonia-lowering strategies and non-absorbable disaccharides are currently considered the cornerstone therapy. Non-absorbable antibiotics, such as neomycin and paramomycin, are effective in treatment of acute HE episodes but their prolonged use for recurrence prevention is hampered by possible side-effects. To overcome these limitations, rifaximin use has been proposed. Rifaximin has been shown to be not superior to non-absorbable disaccharides for either HE treatment or prevention, with a similar incidence of side-effects. Cirrhosis significantly increases rifaximin absorption and this could be a cause for concern. Following long-term rifaximin therapy, Clostridium difficile colitis has been observed and Candida albicans has been isolated from 20% of patients. In addition, selection of resistant mutants of both Gram-negative and -positive bacteria in the gastrointestinal tract cannot be definitely ruled out. Electrolyte alterations (sodium and potassium) have been reported during rifaximin therapy, a warning for its long-term use in cirrhotics. Moreover, a potential interference with vitamin K production should be considered which could further impair the already altered clotting status of these patients. The therapeutic cost of rifaximin is markedly higher than non-absorbable disaccharides. While waiting for further safety data, caution should be used to limit the use of rifaximin therapy for a very short-term period in selected HE cirrhotics not responding to non-absorbable disaccharides.

Abstract
Hepatic encephalopathy (HE) represents a continuum of transient and reversible neurologic and psychiatric dysfunction. It is a reversible state of impaired cognitive function or altered consciousness in patients with liver disease or portosystemic shunting. Over the last several years, high-quality studies have been conducted on various pharmacologic therapies for HE; as more data emerge, it is hoped that HE will become a more easily treated complication of decompensated liver disease. In the interim, it is important that physicians continue to screen for minimal HE and treat patients early in addition to continuing to provide current treatments of overt HE.

Abstract
BACKGROUND The subjectivity of the West-Haven criteria (WHC) hinders hepatic encephalopathy (HE) evaluation. The new HE classification has emphasised assessment of orientation. The modified-orientation log (MO-log, eight questions, scores 0-24; 24 normal) is adapted from a validated brain injury measure. AIM To validate MO-log for HE assessment in cirrhosis. METHODS Cirrhotics admitted with/without HE were administered MO-log. We collected cirrhosis/HE details, admission/daily MO-logs and WHC (performed by different examiners), time to reach normal mentation (MO-log ≥23) and MO-log/WHC change (Δ) over day 1. Outcomes were in-hospital mortality, duration to normal mentation and length-of-stay (LOS). Regressions were performed for each outcome. MO-log inter-rater reliability was measured. RESULTS Ninety-six HE (55 ± 8 years, MELD 21) and 20 non-HE (54 ± 5 years, MELD 19) in-patients were included. In HE patients, median admission WHC was 3 (range 1-4). Mean MO-log was 12 ± 8 (range 0-22). Their LOS was 6 ± 5 days and 13% died. Time to reach normal mentation was 2.4 ± 1.7 days. Concurrent validity: there was a significant negative correlation between admission MO-log and WHC (r = -0.79, P < 0.0001). Discriminant validity: admission MO-logs were significantly lower in those who died (7 vs. 12, P = 0.03) and higher in those admitted without HE (23.6 vs. 12, P < 0.0001). MO-log improved in 69% on day 1 (ΔMO-log 4 ± 8) which was associated with lower duration to normal mentation (2 vs. 3.5 days, P = 0.03) and mortality (3% vs.43%, P < 0.0001), not ΔWHC. Regression models for all outcomes included admission/ΔMO-log but not WHC as a predictor. Inter-rater reliability: ICC for MO-log inter-rater observations was 0.991. CONCLUSIONS Modified-orientation log is a valid tool for assessing severity and is better than West-Haven criteria in predicting outcomes in hospitalised hepatic encephalopathy patients.

Abstract
Hepatic encephalopathy (HE) represents the effects of liver dysfunction on the brain. When HE is clinically obvious (eg, confusion, poor judgment, personality change), it is termed overt HE. The severity of HE is measured by different methods. Assessing the severity of HE is important for determining patient prognosis and effectiveness of therapy. This article discusses the different methods for grading HE, including clinical rating scales, neuropsychological tests, and neurophysiologic measures.

Abstract
Hepatic encephalopathy (HE) is a potentially reversible state of impaired cognitive function or altered consciousness in patients with liver disease or portosystemic shunting. Overt HE is a particularly pressing problem. Given the many targets of treatment and lack of a clear singular cause of overt HE, there is no consensus on a single best treatment. Over the past several years, high-quality studies have been conducted on the various pharmacologic therapies for HE and, as more data emerge, hopefully HE will become a much more easily treated complication of decompensated liver disease.

Abstract
Hepatic encephalopathy (HE) is a neuropsychiatric disorder seen in patients with advanced liver disease or porto-systemic shunts. Based on etiology and severity of HE, the World Congress of Gastroenterology has divided HE into categories and sub-categories. Many user-friendly computer-based neuropsychiatric tests are being validated for diagnosing covert HE. Currently, emphasis is being given to view HE deficits as a continuous spectrum rather than distinct stages. Ammonia is believed to play crucial role in pathogenesis of HE via astrocyte swelling and cerebral edema. However, evidence has been building up which supports the synergistic role of oxidative stress, inflammation and neurosteroids in pathogenesis of HE. At present, treatment of HE aims at decreasing the production and intestinal absorption of ammonia. But as the role of new pathogenetic mechanisms becomes clear, many potential new treatment strategies may become available for clinician.

Abstract
Hepatic encephalopathy (HE) is a common complication of cirrhosis that requires careful appraisal of the clinical manifestations, evaluation of the underlying neurological disorders, and assessment of liver function and the portal-systemic circulation. This article reviews recent developments in the assessment of HE and discusses the controversy regarding the use of a categorical or a continuous approach in measuring the severity of this condition. New scales facilitate effective monitoring and assessment of episodic HE. Neuropsychological test batteries and neurophysiological tests are of value for evaluating cognitive function in outpatients and can establish the diagnosis of minimal HE, and the severity of low-grade HE. These tools allow better evaluation of the origin of cognitive complaints and help in estimating the risk of accidents. It is now possible to complete the evaluation with measurement of the effects of cognitive impairment on daily living. In difficult cases, imaging of the brain and portal-systemic circulation with magnetic resonance imaging is especially helpful. Based on these studies, neurological signs and symptoms can be attributed to HE in patients with mild liver disease and in those with complex neurological manifestations. The new methods presented are also valuable for investigating the neurological manifestations occurring after liver transplantation.

Abstract
BACKGROUND The clinical classification of hepatic encephalopathy is largely subjective, which has led to difficulties in designing trials in this field. AIMS To review the current classification of hepatic encephalopathy and to develop consensus guidelines on the design and conduct of future clinical trials. METHODS A round table was convened at the 14th International Society for Hepatic Encephalopathy and Nitrogen Metabolism (ISHEN) meeting. Key discussion points were the nomenclature of hepatic encephalopathy and the selection of patients, standards of care and end-points for assessing the treatment and secondary prevention of hepatic encephalopathy. RESULTS It was generally agreed that severity assessment of hepatic encephalopathy in patients with cirrhosis, whether made clinically or more objectively, should be continuous rather than categorical, and a system for assessing the SONIC (Spectrum of Neuro-cognitive Impairment in Cirrhosis) was proposed. Within this system, patients currently classified as having minimal hepatic encephalopathy and Grade I hepatic encephalopathy would be classified as having Covert hepatic encephalopathy, whereas those with apparent clinical abnormalities would continue to be classified as overt hepatic encephalopathy. Some aspects of the terminology require further debate. Consensus was also reached on the patient populations, standards of care and endpoints to assess clinical trial outcomes. However, some compromises had to be made as there is considerable inter- and intravariability in the availability of some of the more objective surrogate performance markers. CONCLUSIONS The objectives of the round table were met. Robust, defendable guidelines for the conduct of future studies into hepatic encephalopathy have been provided. Outstanding issues are few and will continue to be discussed.

Abstract
Background
Extracorporeal liver support (ELS) systems offer the potential to prolong survival in acute and acute-on-chronic liver failure. However, the literature has been unclear on their specific role and influence on mortality. This meta-analysis aimed to test the hypothesis that ELS improves survival in acute and acute-on-chronic liver failure.
Methods
Clinical trials citing MeSH terms ‘liver failure’ and ‘liver, artificial’ were identified by searching MEDLINE, Embase and the Cochrane registry of randomized controlled trials (RCTs) between January 1995 and January 2010. Only RCTs comparing ELS with standard medical therapy in acute or acute-on-chronic liver failure were included. A predefined data collection pro forma was used and study quality assessed according to Consolidated Standards of Reporting Trials (CONSORT) criteria. Risk ratio was used as the effect size measure according to a random-effects model.
Results
The search strategy revealed 74 clinical studies including 17 RCTs, five case–control studies and 52 cohort studies. Eight RCTs were suitable for inclusion, three addressing acute liver failure (198 participants) and five acute-on-chronic liver failure (157 participants). The mean CONSORT score was 14 (range 11–20). Overall ELS therapy significantly improved survival in acute liver failure (risk ratio 0·70; P = 0·05). The number needed to treat to prevent one death in acute liver failure was eight. No significant survival benefit was demonstrated in acute-on-chronic liver failure (risk ratio 0·87; P = 0·37).
Conclusion
ELS systems appear to improve survival in acute liver failure. There is, however, no evidence that they improve survival in acute-on-chronic liver failure.
