Abstract
BACKGROUND Patients with cirrhosis are susceptible to infections, especially by multidrug-resistant organisms (MDROs). There are limited data on the incidence of culture-positive infections and the validity of Sepsis 3-criteria in patients with cirrhosis admitted to the intensive care unit (ICU) in India, which we aimed to assess. METHODS In this prospective study, we included consecutive patients with cirrhosis admitted to the ICU between November 1, 2021, and April 30, 2022. The primary objective was to compare the outcomes of patients with microbiologically proven infections with those without proven infections. The secondary objective was to assess the predictors of infections and mortality and the impact of drug-resistant organisms. RESULTS A total of 298 patients (9.4% women) were included. The incidence of microbiologically proven infection was 34% (101/298; 95%CI=27.6-41.2). Most patients (61%) had healthcare-associated infections, Gram-negative organisms accounted for 75.3%, and bacteremia was the commonest site. Drug-resistant organisms accounted for 52.5% (53/101; 95%CI=39.3-68.7), of which 39.6% were multidrug-resistant (MDR) and 12.8% were extensively drug-resistant (XDR). Mortality was significantly higher in patients with proven infections than those without (61.4% vs. 44.2%; P=0.007). The sequential organ failure assessment (SOFA) score (OR=1.91; 95%CI=1.04-3.52; P<0.001) and presence of fever and/or positive quick SOFA (qSOFA; OR=1.91;1.04-3.52; P=0.03) were associated with an increased risk of infections. The SOFA score (OR=1.06;95%CI=1.002-1.12; P=0.04), MELD NA score (OR=1.08;95%CI=1.05-1.12; P<0.001), and presence of fever and/or positive qSOFA (OR=2.19; 95%CI=1.27-3.76; P=0.005) predicted mortality. CONCLUSIONS One-third of the patients with cirrhosis admitted to the ICU had microbiologically proven infection, and the mortality rate in such patients was high. SOFA, qSOFA, and fever can predict microbiologically proven infections and mortality in patients with cirrhosis.

Abstract
Prevalence rates of delirium amount to 22.0% within acute-care settings. In contrast, 30-40% of patients with liver cirrhosis may develop hepatic encephalopathy, a condition that has been classified as a syndrome of delirium, based on recent pathophysiology findings. However, the prevalence of delirium in gastroenterology and hepatology units is unknown.The aims of the study were (i) to identify delirium prevalence rates in inpatients of gastroenterology/hepatology wards, (ii) to analyze the delirium motor subtype, and (iii) to assess associations between delirium and patient characteristics.In this monocentric, cross-sectional, epidemiological study, point prevalence was assessed at six time points in three gastroenterology/hepatology units within a German university hospital. Delirium was assessed using the 4 'As' Test (4AT) and delirium subtype by the delirium motor subtype scale. Patient characteristics were collected from patient charts.The sample consisted of 188 patients, aged 18 to 98 years (mean age 64, n=110 male). Of them, 18.1% of patients showed delirium symptoms (61.8% hypoactive, 29.4% mixed, and 8.8% hyperactive). For the participants aged ≥65 years (n=96), prevalence of delirium amounted to 26.0%. Significant associations were observed between delirium and the following characteristics: age (p=0.001), length of hospital stay until assessment (p=0.043), cerebrovascular disease (p=0.002), dementia (p=0.010), diabetes mellitus with chronic complications (p=0.012), and gender (nonsignificant trend, p=0.050), while no association was detected between moderate or severe liver disease and delirium (p=0.414).In conclusion, overall prevalence rates of delirium were rather low and did not increase in patients with liver disease.

Neurofilament Light Chain Protein in Plasma and Extracellular Vesicles Is Associated with Minimal Hepatic Encephalopathy and Responses to Rifaximin Treatment in Cirrhotic Patients. Int J Mol Sci 2023; 24:14727. [PMID: 37834174 PMCID: PMC10572420 DOI: 10.3390/ijms241914727] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/04/2023] [Revised: 09/19/2023] [Accepted: 09/27/2023] [Indexed: 10/15/2023] Open
Abstract
Neurofilament light chain protein (NfL) levels reflect neuronal damage in several neurological diseases and have been proposed as a possible biomarker. Plasma extracellular vesicles (EVs) could play an important role as mediators of the inflammatory changes associated with inducing minimal hepatic encephalopathy (MHE) in cirrhotic patients. This study investigated the association of NfL levels in plasma and EVs with the presence of MHE in cirrhotic patients, and with responses to rifaximin treatment. The NfL levels in plasma and EVs were assessed in 71 patients with liver cirrhosis (40 with MHE and 31 without MHE) and 26 controls. A total of 31 patients with MHE received rifaximin treatment. We examined changes in NfL levels in plasma and EVs before and after 6 months of rifaximin treatment. The NfL measures were correlated with cognitive alterations and plasma inflammatory cytokines. MHE patients showed increased plasma levels of NfL, which were reverted after rifaximin treatment in patients who responded to treatment. The NfL content in EVs also showed a reversal pattern in MHE patients treated with rifaximin. In multivariable analyses, NfL levels were independently associated with the presence of MHE. We also showed that patients with high levels of both ammonia and fractalkine had significantly higher NfL levels than patients with low levels of least one of these parameters. Rifaximin treatment in MHE patients showed promising results in improving axonal damage, suggesting that rifaximin may have therapeutic benefits against disease progression in MHE.

Abstract
INTRODUCE The purpose of this study was to establish a comprehensive prognosis nomogram for patients with liver cirrhosis complicated with hepatic encephalopathy (HE) in the intensive care unit (ICU) and to evaluate the predictive value of the nomogram. METHOD This study analyzed 620 patients with liver cirrhosis complicated with HE from the Medical Information Mart for Intensive Care III(MIMIC-III) database. The patients were randomly divided into two groups in a 7-to-3 ratio to form a training cohort (n = 434) and a validation cohort (n = 176). Cox regression analyses were used to identify associated risk variables. Based on the multivariate Cox regression model results, a nomogram was established using associated risk predictor variables to predict the 90-day survival rate of patients with cirrhosis complicated with HE. The new model was compared with the Sequential organ failure assessment (SOFA) scoring model in terms of the concordance index (C-index), the area under the curve (AUC) of receiver operating characteristic (ROC) analysis, the net reclassification improvement (NRI), the integrated discrimination improvement (IDI), calibration curve, and decision curve analysis (DCA). RESULTS This study showed that older age, higher mean heart rate, lower mean arterial pressure, lower mean temperature, higher SOFA score, higher RDW, and the use of albumin were risk factors for the prognosis of patients with liver cirrhosis complicated with HE. The use of proton pump inhibitors (PPI) was a protective factor. The performance of the nomogram was evaluated using the C-index, AUC, IDI value, NRI value, and DCA curve, showing that the nomogram was superior to that of the SOFA model alone. Calibration curve results showed that the nomogram had excellent calibration capability. The decision curve analysis confirmed the good clinical application ability of the nomogram. CONCLUSION This study is the first study of the 90-day survival rate prediction of cirrhotic patients with HE in ICU through the data of the MIMIC-III database. It is confirmed that the eight-factor nomogram has good efficiency in predicting the 90-day survival rate of patients.

Abstract
Advanced chronic liver disease (ACLD) represents a complex and multifactorial clinical entity characterized by liver dysfunction and associated complications. In recent years, the significance of nutritional status in ACLD prognosis has gained considerable attention. This review article delves into the multifactorial pathogenesis of malnutrition in ACLD and its profound consequences for health outcomes. We explore the clinical implications of secondary sarcopenia in ACLD and highlight the critical relevance of frailty in both decompensated and compensated ACLD. A specific focus of this review revolves around branched-chain amino acids (BCAAs) and their pivotal role in managing liver disease. We dissect the intricate relationship between low Fischer's ratio and BCAA metabolism in ACLD, shedding light on the molecular mechanisms involved. Furthermore, we critically evaluate the existing evidence regarding the effects of BCAA supplementation on outcomes in ACLD patients, examining their potential to ameliorate the nutritional deficiencies and associated complications in this population.

Abstract
BACKGROUND Transjugular intrahepatic portosystemic shunt (TIPS) can be an effective treatment for cirrhotic patients who develop variceal bleeding and ascites. However, TIPS placement is associated with an increased risk of developing hepatic encephalopathy (HE). Recently, there have been efforts to use the typical medical therapies prophylactically in patients undergoing TIPS placement to prevent post-TIPS HE. METHODS We conducted literature searches in MEDLINE, Embase, CINAHL, Scopus, and Cochrane to examine studies that use prophylactic medical therapy for preventing post-TIPS HE. A narrative synthesis and grading of recommendations assessment assessment were done for all studies. Meta-analysis was performed for eligible studies using the Mantel-Haenszel method random-effects model. Nine hundred twenty-one articles were screened and 5 studies were included in the study after 2 levels of screening. The medications studied were rifaximin, lactulose, lactitol, L-Ornithine-L-aspartate (LOLA), albumin, and combination therapies. RESULTS Narrative results showed that lactulose, lactitol, LOLA and albumin prophylaxis were not associated with reduction in HE occurrence or mortality. A combination of rifaximin and lactulose was found to be associated with lower occurrence of HE, and the results were not different when LOLA was added. Meta-analysis (n = 3) showed that rifaximin treatment was not associated with changes in HE occurrences. CONCLUSION In conclusion, a vast majority of medications were not found to be effective post-TIPS HE prophylaxis when used alone. A rifaximin and lactulose combination therapy may be beneficial. Overall, there is significant limitation in the current data and more studies are needed to yield more robust meta-analysis results in the future.

An orally deliverable ornithine-based self-assembling polymer nanomedicine ameliorates hyperammonemia in acetaminophen-induced acute liver injury. Acta Biomater 2023; 168:515-528. [PMID: 37433359 DOI: 10.1016/j.actbio.2023.07.005] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/29/2023] [Revised: 06/20/2023] [Accepted: 07/06/2023] [Indexed: 07/13/2023]
Abstract
l-Ornithine (Orn) is a core amino acid responsible for ammonia detoxification in the body via the hepatic urea cycle. Clinical studies in Orn therapy have focused on interventions for hyperammonemia-associated diseases, such as hepatic encephalopathy (HE), a life-threatening neurological symptom affecting more than 80% of patients with liver cirrhosis. However, its low molecular weight (LMW) causes Orn to diffuse nonspecifically and be rapidly eliminated from the body after oral administration, resulting in unfavorable therapeutic efficacy. Hence, Orn is constantly supplied by intravenous infusion in many clinical settings; however, this treatment inevitably decreases patient compliance and limits its application in long-term management. To improve the performance of Orn, we designed self-assembling polyOrn-based nanoparticles for oral administration through ring-opening polymerization of Orn-N-carboxy anhydride initiated with amino-ended poly(ethylene glycol), followed by acylation of free amino groups in the main chain of the polyOrn segment. The obtained amphiphilic block copolymers, poly(ethylene glycol)-block-polyOrn(acyl) (PEG-block-POrn(acyl)), enabled the formation of stable nanoparticles (NanoOrn(acyl)) in aqueous media. We employed the isobutyryl (iBu) group for acyl derivatization in this study (NanoOrn(iBu)). In the healthy mice, daily oral administration of NanoOrn(iBu) for one week did not induce any abnormalities. In the mice exhibiting acetaminophen (APAP)-induced acute liver injury, oral pretreatment with NanoOrn(iBu) effectively reduced systemic ammonia and transaminases levels compared to the LMW Orn and untreated groups. The results suggest that the application of NanoOrn(iBu) is of significant clinical value with the feasibility of oral delivery and improvement in APAP-induced hepatic pathogenesis. STATEMENT OF SIGNIFICANCE: Liver injury is often accompanied by hyperammonemia, a life-threatening condition characterized by elevated blood ammonia levels. Current clinical treatments for reducing ammonia typically entail the invasive approach of intravenous infusion, involving the administration of l-ornithine (Orn) or a combination of Orn and L-aspartate. This method is employed due to the poor pharmacokinetics associated with these compounds. In our pursuit of enhancing therapy, we have developed an orally administrable nanomedicine based on Orn-based self-assembling nanoparticle (NanoOrn(iBu)), which provides sustained Orn supply to the injured liver. Oral administration of NanoOrn(iBu) to healthy mice did not cause any toxic effects. In a mouse model of acetaminophen-induced acute liver injury, oral administration of NanoOrn(iBu) surpassed Orn in reducing systemic ammonia levels and liver damage, thereby establishing NanoOrn(iBu) as a safe and effective therapeutic option.

Abstract
We aim to develop a nomogram to predict overt hepatic encephalopathy (OHE) after transjugular intrahepatic portosystemic shunt (TIPS) in patients with portal hypertension, according to demographic/clinical indicators such as age, creatinine, blood ammonia, indocyanine green retention rate at 15 min (ICG-R15) and percentage of Portal pressure gradient (PPG) decline. In this retrospective study, 296 patients with portal hypertension who received elective TIPS in Beijing Shijitan Hospital from June 2018 to June 2020 were included. These patients were randomly divided into a training cohort (n = 207) and a validation cohort (n = 89). According to the occurrence of OHE, patients were assigned to OHE group and non-OHE group. Both univariate and multivariate analyses were performed to determine independent variables for predicting OHE after TIPS. Accordingly, receiver operating characteristic (ROC) curve, calibration curve, and decision curve analysis (DCA) were used to compare the accuracy and superiority of a novel model with conventional Child-Pugh and MELD scoring model. Age (OR 1.036, 95% CI 1.002-1.070, p = 0.037), Creatinine (OR 1.011, 95% CI 1.003-1.019, p = 0.009), Blood ammonia (OR 1.025, 95% CI 1.006-1.044, p = 0.011), ICG-R15 (OR 1.030, 95% CI 1.009-1.052, p = 0.004) and Percentage decline in PPG (OR 1.068, 95% CI 1.029-1.109, p = 0.001) were independent risk factors for OHE after TIPS using multifactorial analysis. A nomogram was constructed using a well-fit calibration curve for each of these five covariates. When compared to Child-Pugh and MELD score, this new nomogram has a better predictive value (C-index = 0.828, 95% CI 0.761-0.896). Consistently, this finding was reproduceable in validation cohort and confirmed with DCA. A unique nomogram was developed to predict OHE after TIPS in patients with PHT, with a high prediction sensitivity and specificity performance than commonly applied scoring systems.

Do the stent blind insertion into the main portal vein (MPV) and stent diameter influence the surgical outcome of the transjugular intrahepatic portosystemic shunt (TIPS)? Comput Biol Med 2023; 164:107306. [PMID: 37542920 DOI: 10.1016/j.compbiomed.2023.107306] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/20/2023] [Revised: 06/24/2023] [Accepted: 07/28/2023] [Indexed: 08/07/2023]
Abstract
Transjugular intrahepatic portosystemic shunt (TIPS) surgery is a clinical intervention to treat portal hypertension (PH) by deploying a covered stent to establish a shunt path for the portal vein (PV) system, and proper surgical strategy is of great importance to balance the shunt effect and the risk of complications. To understand the clinical strategies of the stent blind insertion and stent selection in clinic, this study investigated the effects of varying stent insertion positions and diameters on the PV hemodynamics and the shunt effect by computational fluid dynamics (CFD) analysis of five post-TIPS subjects. The results showed that the successful TIPS surgeries of the five PH subjects were confirmed by quantifying their pressure drops. The stent insertion positions at the main portal vein (MPV) slightly affected the clinically concerned hemodynamic indexes (i.e., MPV pressure, stent-outlet velocity) and the shunt index (SI). This indicated that the position of the stent going into the MPV may not need to be deliberately selected. Moreover, the covered stents with 6 mm and 8 mm diameters slightly influenced the hemodynamics as well, but the large-diameter stent better improved the shunt effect compared to the small-diameter one. Despite this, the 6 mm stent was suggested thanks to the higher risk of the hepatic encephalopathy (HE) observed in clinic, which indicated the excessive shunt of the 8 mm stent. The current work revealed the effects of different TIPS strategies on the surgical outcome, and could be useful for potential clinical practices.

EncephalApp Stroop Test for covert hepatic encephalopathy screening in Tunisian cirrhotic patients. F1000Res 2023; 11:686.

Abstract
Background: Covert hepatic encephalopathy (CHE) is underdiagnosed and is difficult to detect. The EncephalApp Stroop test is validated for its screening. The aim of the study was to define Tunisian norms for the test based on healthy controls norms and to estimate the prevalence of CHE in cirrhotic Tunisian patients. Methods: A prospective, multicenter, cross-sectional study was conducted. Ambulatory or hospitalized cirrhotic patients aged 40 years and over were recruited at 11 centers. Healthy subjects aged 40 years and over were recruited at 8 centers. We used a translated Arabic version of the streamlined EncephalApp Stroop test. The task has two components: "Off" and "On" state depending on the discordance or concordance of the stimuli. Results: 142 patients were included. The mean age was 57.26 years [40-86]. 40 (28.17%) of cirrhotic patients who were included were diagnosed as having a minimal hepatic encephalopathy or CHE. Among the ineligible patients, 22 had overt hepatic encephalopathy. If we consider these patients, the overall prevalence rate of CHE was around 24.39% in cirrhotic patients. It was more frequent in women (34.21% vs 25.96%), and in patients whose level of school education is between 6 and 13 years. Its prevalence does not appear to be affected by gender, MELD score, etiology of cirrhosis and age group of patients, as these variables were independent with respective p according to the chi-square test 0.413; 0.736; 0.663 and 0.1. The stroop times (On / Off and On + Off) correlated significantly with each other, are associated significantly and positively with age (respective Pearson coefficients: 0.578; 0.567 and 0.6). The more the age increases, the more the stroop response times increases (p > 10 -3). Conclusions: EncephalApp Stroop test was an efficient screening tool for CHE in Tunisian cirrhotic patients.

Type 2 diabetes, hepatic decompensation, and hepatocellular carcinoma in patients with non-alcoholic fatty liver disease: an individual participant-level data meta-analysis. Lancet Gastroenterol Hepatol 2023; 8:829-836. [PMID: 37419133 PMCID: PMC10812844 DOI: 10.1016/s2468-1253(23)00157-7] [Citation(s) in RCA: 27] [Impact Index Per Article: 27.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/11/2023] [Revised: 05/16/2023] [Accepted: 05/17/2023] [Indexed: 07/09/2023]
Abstract
BACKGROUND Data are scarce regarding the development of hepatic decompensation in patients with non-alcoholic fatty liver disease (NAFLD) with and without type 2 diabetes. We aimed to assess the risk of hepatic decompensation in people with NAFLD with and without type 2 diabetes. METHODS We did a meta-analysis of individual participant-level data from six cohorts in the USA, Japan, and Turkey. Included participants had magnetic resonance elastography between Feb 27, 2007, and June 4, 2021. Eligible studies included those with liver fibrosis characterisation by magnetic resonance elastography, longitudinal assessment for hepatic decompensation and death, and included adult patients (aged ≥18 years) with NAFLD, for whom data were available regarding the presence of type 2 diabetes at baseline. The primary outcome was hepatic decompensation, defined as ascites, hepatic encephalopathy, or variceal bleeding. The secondary outcome was the development of hepatocellular carcinoma. We used competing risk regression using the Fine and Gray subdistribution hazard ratio (sHR) to compare the likelihood of hepatic decompensation in participants with and without type 2 diabetes. Death without hepatic decompensation was a competing event. FINDINGS Data for 2016 participants (736 with type 2 diabetes; 1280 without type 2 diabetes) from six cohorts were included in this analysis. 1074 (53%) of 2016 participants were female with a mean age of 57·8 years (SD 14·2) years and BMI of 31·3 kg/m2 (SD 7·4). Among 1737 participants (602 with type 2 diabetes and 1135 without type 2 diabetes) with available longitudinal data, 105 participants developed hepatic decompensation over a median follow-up time of 2·8 years (IQR 1·4-5·5). Participants with type 2 diabetes had a significantly higher risk of hepatic decompensation at 1 year (3·37% [95% CI 2·10-5·11] vs 1·07% [0·57-1·86]), 3 years (7·49% [5·36-10·08] vs 2·92% [1·92-4·25]), and 5 years (13·85% [10·43-17·75] vs 3·95% [2·67-5·60]) than participants without type 2 diabetes (p<0·0001). After adjustment for multiple confounders (age, BMI, and race), type 2 diabetes (sHR 2·15 [95% CI 1·39-3·34]; p=0·0006) and glycated haemoglobin (1·31 [95% CI 1·10-1·55]; p=0·0019) were independent predictors of hepatic decompensation. The association between type 2 diabetes and hepatic decompensation remained consistent after adjustment for baseline liver stiffness determined by magnetic resonance elastography. Over a median follow-up of 2·9 years (IQR 1·4-5·7), 22 of 1802 participants analysed (18 of 639 with type 2 diabetes and four of 1163 without type 2 diabetes) developed incident hepatocellular carcinoma. The risk of incident hepatocellular carcinoma was higher in those with type 2 diabetes at 1 year (1·34% [95% CI 0·64-2·54] vs 0·09% [0·01-0·50], 3 years (2·44% [1·36-4·05] vs 0·21% [0·04-0·73]), and 5 years (3·68% [2·18-5·77] vs 0·44% [0·11-1·33]) than in those without type 2 diabetes (p<0·0001). Type 2 diabetes was an independent predictor of hepatocellular carcinoma development (sHR 5·34 [1·67-17·09]; p=0·0048). INTERPRETATION Among people with NAFLD, the presence of type 2 diabetes is associated with a significantly higher risk of hepatic decompensation and hepatocellular carcinoma.

Abstract
Adverse drug events (ADEs) are responsible for a significant number of hospital admissions and fatalities. Machine learning models have been developed to assess the individual patient risk of having an ADE. In this article, we have reviewed studies addressing the prediction of ADEs in observational health data with machine learning. The field of individualised ADE prediction is rapidly emerging through the increasing availability of additional data modalities (e.g., genetic data, screening data, wearables data) and advanced deep learning models such as transformers. Consequently, personalised adverse drug event predictions are becoming more feasible and tangible.

MRI-AST (MAST) Score Accurately Predicts Major Adverse Liver Outcome, Hepatocellular Carcinoma, Liver Transplant, and Liver-Related Death. Clin Gastroenterol Hepatol 2023; 21:2570-2577.e1. [PMID: 36813013 DOI: 10.1016/j.cgh.2023.02.003] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/22/2022] [Revised: 01/17/2023] [Accepted: 02/03/2023] [Indexed: 02/24/2023]
Abstract
BACKGROUND & AIMS The MRI-AST (MAST) score accurately identifies patients with at-risk nonalcoholic steatohepatitis, defined as nonalcoholic steatohepatitis with nonalcoholic fatty liver disease activity score ≥4 and fibrosis stage ≥2 at highest risk for disease progression. It is important to determine the robustness of the MAST score in predicting major adverse liver outcomes (MALO), hepatocellular carcinoma (HCC), liver transplant, and death. METHODS This retrospective analysis included patients with nonalcoholic fatty liver disease from a tertiary care center who underwent magnetic resonance imaging proton density fat fraction, magnetic resonance elastography, and laboratory testing within 6 months from 2013 to 2022. Other causes of chronic liver disease were excluded. Hazard ratios between logit MAST and MALO (ascites, hepatic encephalopathy, or bleeding esophageal varices), liver transplant, HCC, or liver-related death were computed using a Cox proportional hazards regression model. We computed the hazard ratio of MALO or death associated with MAST scores 0.165-0.242 and 0.242-1.000, using MAST scores 0.000-0.165 as the reference group. RESULTS Among 346 total patients, average age was 58.8 years with 52.9% females and 34.4% with type 2 diabetes. Average alanine aminotransferase was 50.7 IU/L (24.3-60.0 IU/L), aspartate aminotransferase was 38.05 IU/L (22.00-41.00 IU/L), platelets were 242.9 × 109/L (193.8-290.0 × 109/L), proton density fat fraction was 12.90% (5.90%-18.22%), and liver stiffness on magnetic resonance elastography was 2.75 kPa (2.07-2.90 kPa). Median follow-up was 29.5 months. Fourteen had adverse outcomes, including 10 MALO, 1 HCC, 1 liver transplant, and 2 liver-related deaths. The Cox regression of MAST versus adverse event rate had a hazard ratio of 2.01 (95% confidence interval, 1.59-2.54; P < .0001) for each 1 logit unit increases in MAST. The corresponding Harrell concordance statistic (C statistic) was 0.919 (95% confidence interval, 0.865-0.953). The MAST score ranges of 0.165-0.242 and 0.242-1.0, respectively, had adverse event rate hazard ratio of 7.75 (1.40-42.9; P = .0189) and 22.11 (6.59-74.2; P < .0000) relative to MAST 0-0.165. CONCLUSIONS The MAST score noninvasively identifies at-risk nonalcoholic steatohepatitis and accurately predicts MALO, HCC, liver transplant, and liver-related death.

Abstract
Clinical trials have been a central driver of change and have provided the evidence base necessary to advance new therapies for liver diseases. This review provides a perspective on the status of trials in hepatology and a vantage point into the emerging capabilities and external forces that will shape the conduct of clinical trials in the future. The adaptations to clinical trial operations in response to the disruptions by the COVID-19 pandemic and opportunities for innovation in hepatology trials are emphasized. Future trials in hepatology will be driven by unmet therapeutic needs and fueled by technological advances incorporating digital capabilities with expanded participant-derived data collection, computing, and analytics. Their design will embrace innovative trial designs adapted to these advances and that emphasize broader and more inclusive participant engagement. Their conduct will be further shaped by evolving regulatory needs and the emergence of new stakeholders in the clinical trials ecosystem. The evolution of clinical trials will offer unique opportunities to advance new therapeutics that will ultimately improve the lives of patients with liver diseases.

Background and aims Limited data exist on strategies other than hepatic venous pressure gradient (HVPG) estimation to predict future events in patients with cirrhosis presenting with variceal bleed (VB) but are otherwise compensated. We assessed whether liver stiffness measurement (LSM) during VB episode could accurately predict this risk. Methods Consecutive patients with cirrhosis with VB as their index decompensation event underwent HVPG and LSM estimation during the VB episode in this prospective study. New onset further decompensation events (ascites, VB, encephalopathy) was assessed over follow-up. The performance characteristics of postbleed LSM were compared with model for end stage liver disease (MELD) score and HVPG to predict future decompensation and were cross-validated. Results Mean age of the cohort (n = 68) was 44.2 years and alcohol-related liver disease (55.9%) was the most common etiology. Over a median follow-up of 14 (9-18) months, 18(26.4%) patients developed further decompensation with ascites being the most common event. Patients with further decompensation had a higher median postbleed LSM [60.5 kPa (53-70) vs. 25 kPa (18-34), P < 0.001], HVPG [ 19 mm Hg vs. 16 mmHg, P = 0.005], and MELD score [ 12.5 (11-14.7) vs. 10 (8-12) P < 0.001]. The area under receiver-operator characteristics curve for postbleed LSM [0.928 (95%CI: 0.868-0.988)] was higher than both HVPG [0.733(0.601-0.865), P = 0.003] and MELD score [0.776(0.664-0.889), P = 0.019] to predict further decompensation. Optimism-corrected c-statistic using MELD and postbleed LSM was similar to a combination of HVPG, MELD, and postbleed LSM. Conclusion Postbleed LSM is comparable to HVPG estimation in predicting further decompensation events in patients with otherwise compensated cirrhosis presenting with VB.

Abstract
We report a case of portosystemic encephalopathy treated by retrograde transvenous obliteration (RTO) with an antecubital vein approach using a steerable triaxial system. A 77-year-old female was referred to our department complaining of dizziness and tremor. Laboratory data showed hyperammonemia. Contrast-enhanced CT and 3D-CT reconstruction images demonstrated an inferior mesenteric vein (IMV)-left common iliac vein shunt and a splenorenal shunt. The former was treated as a responsible shunt. The spleen volume was 212 mL, and the liver volume was 757 mL; giving a spleen/liver volume ratio of 0.3. Partial splenic artery embolization (PSE) was employed to control portal venous pressure. The hepatic venous pressure gradient (HVPG) changed from 13.2 to 9.6 mm Hg and the spleen/liver volume ratio improved from 0.3 to 0.2 by PSE. Two months after PSE, RTO with an antecubital vein approach using a steerable triaxial system was performed. HVPG changed to 12.5 mm Hg after RTO. Contrast-enhanced CT and 3D-CT reconstruction images 3 days after the procedure demonstrated the thrombus in the IMV-left common iliac vein shunt. We conclude that the antecubital vein approach using a steerable triaxial system is a feasible and minimally invasive technique in RTO for portosystemic shunts.

Abstract
The management of cirrhotic patient with encephalopathy and acute variceal bleeding (AVB) remains a clinical challenge with a high mortality. Early endoscopic therapies are frequently applied in patients with AVB. However, the application of general anesthesia in endoscopic surgery for patients with hepatic encephalopathy (HE) is pretty challenging. The present study aimed to evaluate the possible effect of general anesthesia with tracheal intubation on patient complicated with encephalopathy and AVB during endoscopic procedure. Thirty-six cirrhotic patients with encephalopathy and AVB were retrospectively studied, 14 patients underwent endoscopic treatment under general anesthesia with tracheal intubation, and 22 patients received pharmacological treatment, or and endoscopic therapy without general anesthesia served as the control group. Routine clinical and laboratory data were collected. The total mortality rate was 13.9% (5/36), 2 (14.3%) in the anesthesia group, 3 (13.6%) in the control group. The child-Pugh class of death cases were all grade C, 3 (60%) of them were in the stage IV of HE. The stage of HE was all improved in the 2 groups, 12 (85.8 %) patients were totally recovered from consciousness disturbance in the anesthesia group and 16 (72.7 %) in the control group respectively, the difference between the 2 groups was not significant (P>0.05). Except the death cases, there were still 3 patients in the control group had impaired consciousness at discharge. Child-Pugh score, Child-Pugh class and the stage of HE in the anesthesia group were significantly improved at discharge compared with those before operation. General anesthesia does not aggravate the severity of encephalopathy, and endoscopic treatment under general anesthesia with tracheal intubation is effective for HE patients complicated with AVB.

Abstract
Before the widespread use of the transjugular intrahepatic portosystemic shunt, portal hypertension was addressed by the creation of an operative distal splenorenal shunt (DSRS). DSRS was largely regarded as a safe and effective therapy, though it did have a risk of precipitating hyperammonaemia and hepatic encephalopathy.A woman suffered a gunshot wound to the abdomen. This trauma led to portal vein thrombosis, cavernous transformation of the vein and eventually bleeding oesophageal varices from portal hypertension. A DSRS was created to decrease portal hypertension. Years later, she had profound depression with psychomotor slowing in the setting of hyperammonaemia. To reduce hepatic encephalopathy as a contributor to her neuropsychiatric condition, her shunt was closed. The hyperammonaemia resolved and neuropsychiatric symptoms improved.This case highlights several interesting clinical features, including portal hypertension due to chronic portal vein occlusion, cavernous transformation, a surgical DSRS causing hyperammonaemia and hepatic encephalopathy manifesting as neuropsychiatric symptoms.

Hepatol Commun 2023; 7:e0215. [PMID: 37534941 PMCID: PMC10553020 DOI: 10.1097/hc9.0000000000000215] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/04/2023] [Accepted: 06/07/2023] [Indexed: 08/04/2023] Open
Abstract
BACKGROUND AND AIMS Hepatic encephalopathy (HE) is associated with significant morbidity and mortality for those with cirrhosis. Despite the known benefits of rifaximin use for HE, treatment retention remains low. This study aimed to evaluate the impact of out-of-pocket (OOP) rifaximin cost on treatment retention among commercially insured patients in the United States. METHODS Adult patients with cirrhosis and HE were identified from the IBM MarketScan claims database. Those who began rifaximin treatment between January 1, 2011, and December 1, 2021 were included. Regression models were used to analyze the relationship between patients' 30-day OOP rifaximin cost and rifaximin retention (≥80% eligible days with rifaximin supply) at 180, 360, and 540 days. Models were controlled for patient demographic and clinical characteristics including age, sex, comorbid conditions, Charlson comorbidity index (CCI), and lactulose use. RESULTS A total of 6839 adult patients were included. Most patients were between 55 and 64 years (57.1%), male (60.4%), and living in urban settings (84.6%). Treatment retention was low for all time periods; retention rates for rifaximin were 42%, 25%, and 16% at 180, 360, and 540 days, respectively. In multivariable analysis, 30-day OOP costs of ≥ $150 were associated with a decreased likelihood of rifaximin retention at 180, 360, and 540 days [relative risk (RR) = 0.67, RR = 0.62, and R = 0.60, respectively]. Younger age was associated with reduced treatment retention for all time periods. Metastatic cancer and depression were associated with reduced treatment retention at 180 days (RR = 0.70 and RR = 0.87, respectively). CONCLUSIONS Rates of rifaximin treatment retention are low despite the known benefits of rifaximin use for breakthrough HE. High 30-day OOP cost is associated with reduced rifaximin treatment retention.

Abstract
Acute-on-chronic liver failure (ACLF) is characterized by the presence of chronic liver disease and extrahepatic organ failure and is associated with a high rate of short-term mortality. International societies have sought to define the criteria for ACLF and differ on definitions. Encephalopathy is an important organ failure in ACLF cases and is included as a marker of ACLF across society definitions. Both brain failure and ACLF commonly occur in the presence of a triggering event and in the setting of the large amount of inflammation that ensues. The presence of encephalopathy as a part of ACLF not only increases the chances of mortality but also provides unique challenges in that the patient will be limited in conversations around major decisions such as need for advanced level of care, liver transplant, or even end-of-life decisions. Many decisions need to be made quickly and occur in parallel in the care of patients with encephalopathy and ACLF and include stabilizing the patient, identifying precipitants or alternative diagnoses, and medical management. Infections has emerged as a major trigger for both ACLF and encephalopathy, and special attention should be given to identifying and treating infections as they occur.

Individualized portal pressure gradient threshold based on liver function categories in preventing rebleeding after TIPS. Hepatol Int 2023; 17:967-978.

Abstract
BACKGROUND The evidence in Portal pressure gradient (PPG) < 12 mmHg after transjugular intrahepatic portosystemic shunt (TIPS) for preventing rebleeding mostly comes from observations in uncovered stents era. Moreover, association between Child-Pugh classes and post-TIPS hepatic encephalopathy (HE) has indicated that tolerance of PPG reduction depends on liver function. This study aimed to investigate the optimal PPG for covered TIPS and explore the optimal threshold tailored to the Child-Pugh classes to find individualized PPG to balance rebleeding and overt HE. METHODS This multicenter retrospective study analyzed rebleeding, OHE, and mortality of patients associated with post-TIPS PPGs (8, 10, 12, and 14 mmHg) in the entire cohort and among different Child-Pugh classes. Propensity score matching (PSM) and competing risk analyses were performed for sensitivity analyses. RESULTS We included 2100 consecutively screened patients undergoing TIPS. In all patients, PPG < 12 mmHg reduced rebleeding after TIPS (p = 0.022). In Child-Pugh class A, none of the PPG thresholds were discriminative of clinical outcomes. In Child-Pugh class B, 12 mmHg (p = 0.022) and 14 mmHg (p = 0.037) discriminated rebleeding, but 12 mmHg showed a higher net benefit. In Child-Pugh class C, PPG < 14 mmHg had a lower rebleeding incidence (p = 0.017), and exhibited more net benefit than 12 mmHg. CONCLUSION Different PPG standards may be required for patients with different liver function categories. A PPG threshold < 12 mmHg might be suitable for patients in Child-Pugh class B, while < 14 mmHg might be optimal for patients in Child-Pugh class C.

Abstract
BACKGROUND AND AIM Hepatic decompensation is a major complication of liver cirrhosis. We validated the predictive performance of the newly proposed CHESS-ALARM model to predict hepatic decompensation in patients with hepatitis B virus (HBV)-related cirrhosis and compared it with other transient elastography (TE)-based models such as liver stiffness-spleen size-to-platelet (LSPS), portal hypertension (PH), varices risk scores, albumin-bilirubin (ALBI), and albumin-bilirubin-fibrosis-4 (ALBI-FIB-4). METHODS Four hundred eighty-two patients with HBV-related liver cirrhosis between 2006 and 2014 were recruited. Liver cirrhosis was clinically or morphologically defined. The predictive performance of the models was assessed using a time-dependent area under the curve (tAUC). RESULTS During the study period, 48 patients (10.0%) developed hepatic decompensation (median 93 months). The 1-year predictive performance of the LSPS model (tAUC = 0.8405) was higher than those of the PH model (tAUC = 0.8255), ALBI-FIB-4 (tAUC = 0.8168), ALBI (tAUC = 0.8153), CHESS-ALARM (tAUC = 0.8090), and variceal risk score (tAUC = 0.7990). The 3-year predictive performance of the LSPS model (tAUC = 0.8673) was higher than those of the PH risk score (tAUC = 0.8670), CHESS-ALARM (tAUC = 0.8329), variceal risk score (tAUC = 0.8290), ALBI-FIB-4 (tAUC = 0.7730), and ALBI (tAUC = 0.7451). The 5-year predictive performance of the PH risk score (tAUC = 0.8521) was higher than those of the LSPS (tAUC = 0.8465), varices risk score (tAUC = 0.8261), CHESS-ALARM (tAUC = 0.7971), ALBI-FIB-4 (tAUC = 0.7743), and ALBI (tAUC = 0.7541). However, there was no significant difference in the predictive performance among all models at 1, 3, and 5 years (P > 0.05). CONCLUSIONS The CHESS-ALARM score was able to reliably predict hepatic decompensation in patients with HBV-related liver cirrhosis and showed similar performance to the LSPS, PH, varices risk scores, ALBI, and ALBI-FIB-4.

Abstract
Hepatic encephalopathy (HE) is a challenging complication of liver disease that is associated with substantial morbidity and mortality. Branched-chain amino acid (BCAA) supplementation in the management of HE is a debated topic. This narrative review aims to provide an up-to-date review of the topic and includes studies featuring patients with hepatocellular carcinoma. A review of the literature was performed using the online databases MEDLINE and EMBASE for studies between 2002 and December 2022. Keywords 'branched-chain amino acids', 'liver cirrhosis' and 'hepatic encephalopathy' were used. Studies were assessed for inclusion and exclusion criteria. Of 1045 citations, 8 studies met the inclusion criteria. The main outcomes reported for HE was changed in minimal HE (MHE) (n = 4) and/or incidence of overt HE (OHE) (n = 7). Two of the 4 studies reporting on MHE had improvement in psychometric testing in the BCAA group, but there was no change in the incidence of OHE in any of the 7 papers in the BCAA group. There were few adverse effects of BCAA supplementation. This review found weak evidence for BCAA supplementation for MHE, and no evidence for BCAAs for OHE. However, given the relative paucity and methodological heterogeneity of the current research, there is scope for future studies to examine the effects of varying timing, dosage, and frequency of BCAAs on outcomes such as HE. Importantly, research is also needed to examine BCAAs in conjunction with standard therapies for HE such as rifaximin and/or lactulose.

Abstract
BACKGROUND Additional therapies for hepatic encephalopathy (HE) treatment are warranted. There are data evaluating the use of zinc for HE; however, clinical outcomes, specifically in the United States, are unknown. OBJECTIVE To compare 30-day and 1-year all-cause readmission rates in patients with cirrhosis complicated by HE on lactulose and rifaximin to those on lactulose, rifaximin, and zinc. METHODS This retrospective study included patients admitted with documented cirrhosis and home medications of lactulose and rifaximin, with or without zinc. Patients were stratified into 2 groups: those receiving lactulose and rifaximin for HE (control) and those receiving lactulose, rifaximin, and zinc for HE (treatment). The primary outcomes were 30-day and 1-year all-cause readmission rates. RESULTS One-hundred fifty-seven patients were included (102 in control group, 55 in treatment group). Regarding 30-day and 1-year all-cause readmission rates, there was no difference between the control and treatment groups. CONCLUSION AND RELEVANCE This is the first study conducted in the United States evaluating zinc for HE treatment. Zinc did not impact 30-day or 1-year all-cause readmission rates. Further studies are warranted to evaluate the potential benefit of zinc for HE, possibly in correlation with Model for End-stage Liver Disease-Sodium (MELD-Na) scores.

Abstract
Acute-on-chronic liver failure (ACLF) is characterized by abrupt decompensation in a patient with chronic liver disease with extrahepatic organ dysfunction and is implicated in an increased risk of mortality. ACLF may be present in approximately 20% to 40% of hospitalized cirrhosis. There are several diagnostic scoring systems for ACLF; one defined by the North American Consortium for Study of End-stage Liver Disease is the presence of acutely decompensated cirrhosis complicated by failure of two or more organ systems: circulatory, renal, neurological, coagulopathy, and/or pulmonary.

Abstract
There are two distinct phases in the natural history of cirrhosis: compensated disease (corresponding to Child Pugh A and early Child Pugh B disease), where the patient may be largely asymptomatic, progressing with increasing portal hypertension and liver dysfunction to decompensated disease (corresponding to Child Pugh late B-C), characterised by the development of overt clinical signs, including jaundice, hepatic encephalopathy (HE), ascites, renal dysfunction and variceal bleeding. The transition from compensated cirrhosis to decompensated cirrhosis (DC) heralds a watershed in the nature and prognosis of the disease. DC is a systemic disease, characterised by multiorgan/system dysfunction, including haemodynamic and immune dysfunction. In this second part of our three-part series on the outpatient management of cirrhosis, we address outpatient management of DC, including management of varices, ascites, HE, nutrition, liver transplantation and palliative care. We also introduce an outpatient DC care bundle. For recommendations on screening for osteoporosis, hepatocellular carcinoma surveillance and vaccination see part one of the guidance. Part 3 of the guidance focusses on special circumstances encountered in patients with cirrhosis, including surgery, pregnancy, travel, management of bleeding risk for invasive procedures and portal vein thrombosis.

Abstract
Hepatic encephalopathy (HE) is a potentially reversible neuropsychiatric syndrome. Often, HE causes cognitive and motor dysfunctions due to an acute or chronic insufficiency of the liver or a shunting between the hepatic portal vein and systemic vasculature. Liver damage induces peripheral changes, such as in the metabolism and peripheral inflammatory responses that trigger exacerbated neuroinflammation. In experimental models, anti-inflammatory strategies have demonstrated neuroprotective effects, leading to a reduction in HE-related cognitive and motor impairments. In this scenario, a growing body of evidence has shown that peripheral and central nervous system inflammation are promising preclinical targets. In this review, we performed an overview of FDA-approved drugs and natural compounds which are used in the treatment of other neurological and nonneurological diseases that have played a neuroprotective role in experimental HE, at least in part, through anti-inflammatory mechanisms. Despite the exciting results from animal models, the available data should be critically interpreted, highlighting the importance of translating the findings for clinical essays.

Abstract
BACKGROUND Hepatic encephalopathy describes the spectrum of neuropsychiatric changes that may complicate the course of cirrhosis and detrimentally affect outcomes. Ammonia plays a key role in its development. Rifaximin is a non-absorbable antibiotic that inhibits urease-producing bacteria and reduces absorption of dietary and bacterial ammonia. OBJECTIVES To evaluate the beneficial and harmful effects of rifaximin versus placebo, no intervention, or non-absorbable disaccharides for: (i) the prevention of hepatic encephalopathy, and (ii) the treatment of minimal and overt hepatic encephalopathy, in people with cirrhosis, both when used alone and when combined with a non-absorbable disaccharide. SEARCH METHODS We searched the Cochrane Hepato-Biliary Group Clinical Trials Register, CENTRAL, MEDLINE, Embase, three other databases, the reference lists of identified papers, and relevant conference proceedings. We wrote to authors and pharmaceutical companies for information on other published, unpublished, or ongoing trials. Searches were performed to January 2023. SELECTION CRITERIA We included randomised clinical trials assessing prevention or treatment of hepatic encephalopathy with rifaximin alone, or with a non-absorbable disaccharide, versus placebo/no intervention, or a non-absorbable disaccharide alone. DATA COLLECTION AND ANALYSIS Six authors independently searched for studies, extracted data, and validated findings. We assessed the design, bias risk, and participant/intervention characteristics of the included studies. We assessed mortality, serious adverse events, health-related quality of life, hepatic encephalopathy, non-serious adverse events, blood ammonia, Number Connection Test-A, and length of hospital stay. MAIN RESULTS We included 41 trials involving 4545 people with, or at risk for, developing hepatic encephalopathy. We excluded 89 trials and identified 13 ongoing studies. Some trials involved participants with more than one type of hepatic encephalopathy or more than one treatment comparison. Hepatic encephalopathy was classed as acute (13 trials), chronic (7 trials), or minimal (8 trials), or else participants were considered at risk for its development (13 trials). The control groups received placebo (12 trials), no/standard treatment (1 trial), or a non-absorbable disaccharide (14 trials). Eighteen trials assessed rifaximin plus a non-absorbable disaccharide versus a non-absorbable disaccharide alone. We classified 11 trials as at high risk of overall bias for mortality and 28 for non-mortality outcomes, mainly due to lack of blinding, incomplete outcome data, and selective reporting. Compared to placebo/no intervention, rifaximin likely has no overall effect on mortality (risk ratio (RR) 0.83, 95% confidence interval (CI) 0.50 to 1.38; P = 48, I2 = 0%; 13 trials, 1007 participants; moderate-certainty evidence), and there may be no overall effect when compared to non-absorbable disaccharides (RR 0.99, 95% CI 0.49 to 1.97; P = 0.97, I2 = 0%; 10 trials, 786 participants; low-certainty evidence). However, there is likely a reduction in the overall risk of mortality when comparing rifaximin plus a non-absorbable disaccharide to a non-absorbable disaccharide alone (RR 0.69, 95% CI 0.55 to 0.86; number needed to treat for an additional beneficial outcome (NNTB) = 22; P = 0.001, I2 = 0%; 14 trials, 1946 participants; moderate-certainty evidence). There is likely no effect on the overall risk of serious adverse events when comparing rifaximin to placebo/no intervention (RR 1.05, 95% CI 0.83 to 1.32; P = 68, I2 = 0%; 9 trials, 801 participants; moderate-certainty evidence) and there may be no overall effect when compared to non-absorbable disaccharides (RR 0.97, 95% CI 0.66 to 1.40; P = 85, I2 = 0%; 8 trials, 681 participants; low-certainty evidence). However, there was very low-certainty evidence that use of rifaximin plus a non-absorbable disaccharide may be associated with a lower risk of serious adverse events than use of a non-absorbable disaccharide alone (RR 0.66, 95% CI 0.45 to 0.98; P = 0.04, I2 = 60%; 7 trials, 1076 participants). Rifaximin likely results in an overall effect on health-related quality of life when compared to placebo/no intervention (mean difference (MD) -1.43, 95% CI -2.87 to 0.02; P = 0.05, I2 = 81%; 4 trials, 214 participants; moderate-certainty evidence), and may benefit health-related quality of life in people with minimal hepatic encephalopathy (MD -2.07, 95% CI -2.79 to -1.35; P < 0.001, I2 = 0%; 3 trials, 176 participants). The overall effect on health-related quality of life when comparing rifaximin to non-absorbable disaccharides is very uncertain (MD -0.33, 95% CI -1.65 to 0.98; P = 0.62, I2 = 0%; 2 trials, 249 participants; very low-certainty evidence). None of the combined rifaximin/non-absorbable disaccharide trials reported on this outcome. There is likely an overall beneficial effect on hepatic encephalopathy when comparing rifaximin to placebo/no intervention (RR 0.56, 95% CI 0.42 to 0.77; NNTB = 5; P < 0.001, I2 = 68%; 13 trials, 1009 participants; moderate-certainty evidence). This effect may be more marked in people with minimal hepatic encephalopathy (RR 0.40, 95% CI 0.31 to 0.52; NNTB = 3; P < 0.001, I2 = 10%; 6 trials, 364 participants) and in prevention trials (RR 0.71, 95% CI 0.56 to 0.91; NNTB = 10; P = 0.007, I2 = 36%; 4 trials, 474 participants). There may be little overall effect on hepatic encephalopathy when comparing rifaximin to non-absorbable disaccharides (RR 0.85, 95% CI 0.69 to 1.05; P = 0.13, I2 = 0%; 13 trials, 921 participants; low-certainty evidence). However, there may be an overall beneficial effect on hepatic encephalopathy when comparing rifaximin plus a non-absorbable disaccharide to a non-absorbable disaccharide alone (RR 0.58, 95% CI 0.48 to 0.71; NNTB = 5; P < 0.001, I2 = 62%; 17 trials, 2332 participants; low-certainty evidence). AUTHORS' CONCLUSIONS Compared to placebo/no intervention, rifaximin likely improves health-related quality of life in people with minimal hepatic encephalopathy, and may improve hepatic encephalopathy, particularly in populations with minimal hepatic encephalopathy and when it is used for prevention. Rifaximin likely has no overall effect on mortality, serious adverse events, health-related quality of life, or hepatic encephalopathy compared to non-absorbable disaccharides. However, when used in combination with a non-absorbable disaccharide, it likely reduces overall mortality risk, the risk of serious adverse events, improves hepatic encephalopathy, reduces the length of hospital stay, and prevents the occurrence/recurrence of hepatic encephalopathy. The certainty of evidence for these outcomes is very low to moderate; further high-quality trials are needed.

Can J Gastroenterol Hepatol 2023; 2023:6164611. [PMID: 37469934 PMCID: PMC10352535 DOI: 10.1155/2023/6164611] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/16/2023] [Revised: 05/07/2023] [Accepted: 07/03/2023] [Indexed: 07/21/2023] Open
Abstract
Objectives The rapidly evolving organ failure and high short-run mortality of acute-on-chronic liver failure (ACLF) are inseparable from the role of systemic inflammatory response. S100A8 and S100A9 are associated with the excessive cytokine storm and play a decisive part within the process of inflammation. We aimed to clarify the role of them in predicting prognosis of hepatitis B virus-related ACLF (HBV-ACLF). Methods S100A8 and S100A9 levels were analyzed in plasma of 187 transplant-free HBV-ACLF patients, 28 healthy controls and 40 chronic hepatitis B (CHB) patients. S100A8 and S100A9 mRNAs were checked in liver samples from 32 HBV-ACLF patients with liver transplantation, 19 patients undergoing surgery for hepatic hemangioma and 10 CHB patients with needle biopsy. Results The plasma levels of the S100A8 and S100A9 were higher in HBV-ACLF patients than in CHB patients (S100A8 : P < 0.001 and S100A9 : P < 0.001) and healthy controls (S100A8 : P < 0.001 and S100A9 : P < 0.001), and similar results were obtained for mRNA expression. Moreover, both proteins were related to ACLF grade, different types of organ failure, and infection, and they correlated with other prognostic scoring systems. S100A8 and S100A9 can dependently predict 28/90-day mortality (28-day: S100A8: hazard ratio (HR): 1.027; 95% confidence interval (CI): 1.007-1.048; P=0.026, S100A9 : HR: 1.009; 95% CI: 1.001-1.017; P=0.007, 90-day: S100A8 : HR: 1.023; 95% CI: 1.011-1.035; P=0.004, S100A9 : HR: 1.008; 95% CI: 1.004-1.012; and P < 0.001). Among all of the scoring systems, the combined scoring model (S100A8 and S100A9 jointly with the Chronic Liver Failure-Consortium Organ Failure score (CLIF-C OFs)) displayed the highest area under the receiver operating curve (0.923 (95% CI, 0.887-0.961)) in the prediction of 90-day mortality. Conclusions S100A8 and S100A9 are promising biomarkers for the analysis of risk stratification and prognosis in ACLF patients. In addition, combining them with the CLIF-C OFs may better predict the prognosis of ACLF.

Abstract
BACKGROUND & AIMS Hospitalizations are a sentinel event in cirrhosis; however, the changing demographics in patients with cirrhosis require updated hospitalization prediction models. Periodontitis is a risk factor for liver disease and potentially progression. The aim of this study was to determine factors, including poor oral health, associated with 3-month hospitalizations in a multi-center cohort of outpatients with cirrhosis. METHODS North American Consortium for Study of End-stage Liver Disease (NACSELD-3), a new study cohort, recruits outpatients with cirrhosis. Cirrhosis details, demographics, minimal hepatic encephalopathy (MHE), frailty, and comorbid conditions including oral health were collected. All patients were followed for 3 months for nonelective hospitalizations. Multi-variable models were created for this outcome using demographics, cirrhosis details, oral health, MHE, frailty, and comorbid conditions with K-fold internal validation using 25%/75% split. RESULTS A total of 442 outpatients (70% men; 37% compensated; Model for End-stage Liver Disease-Sodium, 12; 42% ascites; and 33% prior HE) were included. MHE was found in 70%, frailty in 10%; and both in 8%. In terms of oral health, 15% were edentulous and 10% had prior periodontitis. Regarding 3-month hospitalizations, 14% were admitted for mostly liver-related reasons. These patients were more likely to be decompensated with higher cirrhosis complications, MHE, frailty and periodontitis history. Multi-variable analysis showed prior periodontitis (P = .026), composite MHE + frailty score (P = .0016), ascites (P = .004), prior HE (P = .008), and hydrothorax (P = .004) were associated with admissions using the training and validation subsets. CONCLUSIONS In a contemporaneous, prospective, multi-center cohort study in outpatients with cirrhosis, poor oral health is significantly associated with 3-month hospitalizations independent of portal hypertensive complications, MHE, and frailty. Potential strategies to reduce hospitalizations should consider oral evaluation in addition to MHE and frailty assessment in practice pathways.

Abstract
INTRODUCTION Hepatic encephalopathy (HE) is a neuropsychiatric syndrome, in patients with liver disease, which affects life quality and span. Current treatments are lactulose or rifaximin, acting on gut microbiota. Treatments aiming ammonia levels reduction have been tested with little success. AREAS COVERED Pre-clinical research shows that the process inducing HE involves sequentially: liver failure, altered microbiome, hyperammonemia, peripheral inflammation, changes in immunophenotype and extracellular vesicles and neuroinflammation, which alters neurotransmission impairing cognitive and motor function. HE may be reversed using drugs acting at any step: modulating microbiota with probiotics or fecal transplantation; reducing peripheral inflammation with anti-TNFα, autotaxin inhibitors or silymarin; reducing neuroinflammation with sulforaphane, p38 MAP kinase or phosphodiesteras 5 inhibitors, antagonists of sphingosine-1-phosphate receptor 2, enhancing meningeal lymphatic drainage or with extracellular vesicles from mesenchymal stem cells; reducing GABAergic neurotransmission with indomethacin or golexanolone. EXPERT OPINION A factor limiting the progress of HE treatment is the lack of translation of research advances into clinical trials. Only drugs acting on microbiota or ammonia reduction have been tested in patients. It is urgent to change the mentality on how to approach HE treatment to develop clinical trials to assess drugs acting on the immune system/peripheral inflammation, neuroinflammation or neurotransmission to improve HE.

Dutta N, Kc M, Wang Q, Lim N. Impact of Gastroenterology Consultation on the Clinical Outcomes of Patients Admitted With Hepatic Encephalopathy. Cureus 2023; 15:e41610. [PMID: 37565113 PMCID: PMC10409643 DOI: 10.7759/cureus.41610] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 07/07/2023] [Indexed: 08/12/2023] Open
Abstract
Introduction Hepatic encephalopathy (HE) is a common complication of cirrhosis and a common reason for hospital admission. We aimed to determine whether expert consultation from gastroenterology (GI) leads to better clinical outcomes for inpatients with HE. Methods A retrospective review was performed of all adult patients (age ≥ 18) admitted with HE to a tertiary care hospital between January 2013 and April 2018. Patients who received a GI consult were compared to patients who did not receive a GI consult (No consult group). The primary outcome was hospital length of stay (LOS); secondary outcomes were rates of 30-day hospital readmission and 90-day mortality. Multivariate analysis was conducted to adjust for known confounders. Results Four hundred and twenty-five patients (814 encounters) were included in the study; of these, 236 patients had received a GI consultation for HE. Patients in the GI consult group were younger (mean age 55 vs 58 years, p= 0.02) and had higher Model For End-Stage Liver Disease-sodium (MELD-Na) score (mean MELD-Na 23.5 vs 17.5, p<0.01) compared to patients who did not receive GI consultation. The precipitants of HE were significantly different between the groups: there was more spontaneous bacterial peritonitis (SBP) and GI bleeding (GIB) in the GI consult group and more lactulose non-adherence in the no consult group. There was no difference in the etiology of liver disease between the two groups. Median LOS for the GI consult group was six days vs three days in the no consult group (p<0.01); the incidence rate ratio was 1.79 (95%CI 1.59-2.02, p<0.01) on multivariate analysis. There was no difference in 30-day readmission or 90-day mortality between the two groups. Conclusion GI consultation for patients with HE admitted to a hospital medicine service may be associated with longer LOS. In selected patients admitted with HE, GI consultation may not be necessary to achieve good clinical outcomes.

Abstract
Background Hepatic encephalopathy (HE) in cirrhosis is an extremely challenging complication for patients and care partners. To identify potentially modifiable factors to enhance HE self-management strategies, we conducted a synthesis of quantitative and qualitative research about real-world HE behaviours, knowledge, and experiences. Methods Using the EPPI-Centre's mixed methods synthesis procedure, a systematic literature search in five databases was completed; methods of selected articles underwent critical appraisal followed by descriptive analysis and coded line-by-line of content. Through refutational translation, the findings from the quantitative and qualitative syntheses were juxtaposed to highlight congruencies, incongruencies, or gaps. These findings informed generation of cross-analytical themes that were transformed into action statements. Results The quantitative narrative review of synthesis (n = 17) generated four themes (patients had low awareness of HE and low treatment adherence rates, physicians had a non-uniform approach to non-pharmaceutical therapies). Meta-aggregation of qualitative data from six articles yielded three themes (patients and care partners had low levels of HE awareness, were unfamiliar with HE self-management, and were adherent to treatments). Comparison of findings revealed three congruencies, two gaps, and one incongruency. The combined synthesis yielded two self-management themes: universal patient-oriented cirrhosis HE education and ensuring each health care encounter systematically addresses HE to guarantee health care is continuously modified to meet their needs. Conclusions By drawing on elements of Bloom's Taxonomy and distributed knowledge networks, deliberate patient-oriented HE messaging at all health care encounters is greatly needed to improve health outcomes and reduce care burdens related to HE.

Abstract
Background/Objectives Bacterial infections (BIs) are well-recognized precipitants of hepatic encephalopathy (HE). Nevertheless, there is a paucity of data in patients with HE associated with BI. Our aim was to describe clinical characteristics, recurrence, and prognosis of HE in patients with BI. Methods A prospective study with inclusion of hospitalized cirrhotic patients with BI, followed until discharge, death, or liver transplantation. Results 172 patients (age 57 ± 13, model of end-stage liver disease [MELD]-sodium 22 ± 8) were included. Infections were more commonly due to spontaneous bacterial peritonitis and cellulitis (22% and 23%), non-nosocomial (70%), and associated with systemic inflammatory response syndrome and septic shock in 40% and 9%, respectively. HE was diagnosed in 66 patients (grade ≥2 in 58%). In multivariate analysis, MELD-sodium, albumin, and prior HE were associated with HE at diagnosis of BI. Recurrence of HE was diagnosed in 30 patients (median 13 [interquartile range 5-22] days), more commonly manifested as overt HE (90% vs. 60% at first episode, P = 0.012) and more frequently in patients with hyponatremia (54% vs. 27% for patients without, P < 0.001). In-hospital mortality was 34% and was more common for patients with HE (51% vs. 22%, P < 0.001), irrespective of grade, and for those with recurrence (63% vs. 42%, P < 0.001). In multivariate analysis, HE at diagnosis of infection and MELD-sodium were predictors of mortality. Conclusions HE is frequent in cirrhotic patients with BI and is associated with severity of liver disease, but not with infection. These patients are at increased risk of short-term HE recurrence, especially those with hyponatremia. The presence and recurrence of HE, independent of severity, are associated with in-hospital mortality.

Abstract
Mechanistically, the symptomatology and disease progression of non-alcoholic fatty liver disease (NAFLD) remain poorly understood, which makes therapeutic progress difficult. In this review, we focus on the potential importance of decreased urea cycle activity as a pathogenic mechanism. Urea synthesis is an exclusive hepatic function and is the body's only on-demand and definitive pathway to remove toxic ammonia. The compromised urea cycle activity in NAFLD is likely caused by epigenetic damage to urea cycle enzyme genes and increased hepatocyte senescence. When the urea cycle is dysfunctional, ammonia accumulates in liver tissue and blood, as has been demonstrated in both animal models and patients with NAFLD. The problem may be augmented by parallel changes in the glutamine/glutamate system. In the liver, the accumulation of ammonia leads to inflammation, stellate cell activation and fibrogenesis, which is partially reversible. This may be an important mechanism for the transition of bland steatosis to steatohepatitis and further to cirrhosis and hepatocellular carcinoma. Systemic hyperammonaemia has widespread negative effects on other organs. Best known are the cerebral consequences that manifest as cognitive disturbances, which are prevalent in patients with NAFLD. Furthermore, high ammonia levels induce a negative muscle protein balance leading to sarcopenia, compromised immune function and increased risk of liver cancer. There is currently no rational way to reverse reduced urea cycle activity but there are promising animal and human reports of ammonia-lowering strategies correcting several of the mentioned untoward aspects of NAFLD. In conclusion, the ability of ammonia-lowering strategies to control the symptoms and prevent the progression of NAFLD should be explored in clinical trials.

Abstract
Cirrhosis consists of 2 main stages: compensated and decompensated, the latter defined by the development/presence of ascites, variceal hemorrhage, and hepatic encephalopathy. The survival rate is entirely different, depending on the stage. Treatment with nonselective β-blockers prevents decompensation in patients with clinically significant portal hypertension, changing the previous paradigm based on the presence of varices. In patients with acute variceal hemorrhage at high risk of failure with standard treatment (defined as those with a Child-Pugh score of 10-13 or those with a Child-Pugh score of 8-9 with active bleeding at endoscopy), a pre-emptive transjugular intrahepatic portosystemic shunt (TIPS) improves the mortality rate and has become the standard of care in many centers. In patients with bleeding from gastrofundal varices, retrograde transvenous obliteration (in those with a gastrorenal shunt) and/or variceal cyanoacrylate injection have emerged as alternatives to TIPS. In patients with ascites, emerging evidence suggests that TIPS might be used earlier, before strict criteria for refractory ascites are met. Long-term albumin use is under assessment for improving the prognosis of patients with uncomplicated ascites and confirmatory studies are ongoing. Hepatorenal syndrome is the least common cause of acute kidney injury in cirrhosis, and first-line treatment is the combination of terlipressin and albumin. Hepatic encephalopathy has a profound impact on the quality of life of patients with cirrhosis. Lactulose and rifaximin are first- and second-line treatments for hepatic encephalopathy, respectively. Newer therapies such as L-ornithine L-aspartate and albumin require further assessment.

Abstract
Acute liver failure (ALF) is a rare, acute, potentially reversible condition resulting in severe liver impairment and rapid clinical deterioration in patients without preexisting liver disease. Due to the rarity of this condition, published studies are limited by the use of retrospective or prospective cohorts and lack of randomized controlled trials. Current guidelines represent the suggested approach to the identification, treatment, and management of ALF and represent the official practice recommendations of the American College of Gastroenterology. The scientific evidence was reviewed using the Grading of Recommendations, Assessment, Development and Evaluation process to develop recommendations. When no robust evidence was available, expert opinions were summarized using Key Concepts. Considering the variety of clinical presentations of ALF, individualization of care should be applied in specific clinical scenarios.

Abstract
Acute on chronic liver failure (ACLF) reflects the development of organ failure(s) in a patient with cirrhosis and is associated with high short-term mortality. Given that ACLF has many different 'phenotypes', medical management needs to take into account the relationship between precipitating insult, organ systems involved and underlying physiology of chronic liver disease/cirrhosis. The goals of intensive care management of patients suffering ACLF are to rapidly recognize and treat inciting events (e.g. infection, severe alcoholic hepatitis and bleeding) and to aggressively support failing organ systems to ensure that patients may successfully undergo liver transplantation or recovery. Management of these patients is complex since they are prone to develop new organ failures and infectious or bleeding complications. ICU therapy parallels that applied in the general ICU population in some complications but differs in others. Given that liver transplantation in ACLF is an emerging and evolving field, multidisciplinary teams with expertise in critical care and transplant medicine best accomplish management of the critically ill ACLF patient. The focus of this review is to identify the common complications of ACLF and to describe the proper management in critically ill patients awaiting liver transplantation in our centres, including organ support, prognostic assessment and how to assess when recovery is unlikely.

Abstract
Bile acids (BAs) are synthesized in liver tissue from cholesterol and are an important endocrine regulator and signaling molecule in the liver and intestine. It maintains BAs homeostasis, and the integrity of intestinal barrier function, and regulates enterohepatic circulation in vivo by modulating farnesoid X receptors (FXR) and membrane receptors. Cirrhosis and its associated complications can lead to changes in the composition of intestinal micro-ecosystem, resulting in dysbiosis of the intestinal microbiota. These changes may be related to the altered composition of BAs. The BAs transported to the intestinal cavity through the enterohepatic circulation are hydrolyzed and oxidized by intestinal microorganisms, resulting in changes in their physicochemical properties, which can also lead to dysbiosis of intestinal microbiota and overgrowth of pathogenic bacteria, induction of inflammation, and damage to the intestinal barrier, thus aggravating the progression of cirrhosis. In this paper, we review the discussion of BAs synthesis pathway and signal transduction, the bidirectional regulation of bile acids and intestinal microbiota, and further explore the role of reduced total bile acid concentration and dysregulated intestinal microbiota ratio in the development of cirrhosis, in order to provide a new theoretical basis for the clinical treatment of cirrhosis and its complications.

Abstract
Acute liver failure and chronic liver disease are associated with a wide spectrum of neurological changes, of which the best known is hepatic encephalopathy (HE). Historically, hyperammonemia, causing astrocyte swelling and cerebral oedema, was considered the main etiological factor in the pathogenesis of cerebral dysfunction in patients with acute and/or chronic liver disease. However, recent studies demonstrated a key role of neuroinflammation in the development of neurological complications in this setting. Neuroinflammation is characterized by activation of microglial cells and brain secretion of pro-inflammatory cytokines, such as tumor necrosis factor (TNF)-α, interleukin (IL)-1β, and IL-6, which alter neurotransmission, leading to cognitive and motor dysfunction. Changes in the gut microbiota resulting from liver disease play a crucial role in the pathogenesis of neuroinflammation. Dysbiosis and altered intestinal permeability, resulting in bacterial translocation and endotoxemia, are responsible for systemic inflammation, which can spread to brain tissue and trigger neuroinflammation. In addition, metabolites derived from the gut microbiota can act on the central nervous system and facilitate the development of neurological complications, exacerbating clinical manifestations. Thus, strategies aimed at modulating the gut microbiota may be effective therapeutic weapons. In this review, we summarize the current knowledge on the role of the gut-liver-brain axis in the pathogenesis of neurological dysfunction associated with liver disease, with a particular focus on neuroinflammation. In addition, we highlight emerging therapeutic approaches targeting the gut microbiota and inflammation in this clinical setting.

Abstract
Acute liver failure (ALF) may result in severe neurological complications caused by cerebral edema and elevated intracranial pressure (ICP). Multiple pathogenic mechanisms explain the elevated ICP, and newer hypotheses have been described. While invasive ICP monitoring (ICPM) may have a role in ALF management, these patients are typically coagulopathic and at risk for intracranial hemorrhage. ICPM is the subject of much debate, and significant heterogeneity exists in clinical practice regarding its use. Contemporary ICPM techniques and coagulopathy reversal strategies may be associated with a lower risk of hemorrhage; however, most of the evidence is limited by its retrospective nature and relatively small sample size.

Abstract
The gut microbiota is a pivotal actor in the maintenance of the balance in the complex interconnections of hepato-biliary-pancreatic system. It has both metabolic and immunologic functions, with an influence on the homeostasis of the whole organism and on the pathogenesis of a wide range of diseases, from non-neoplastic ones to tumorigenesis. The continuous bidirectional metabolic communication between gut and hepato-pancreatic district, through bile ducts and portal vein, leads to a continuous interaction with translocated bacteria and their products. Chronic liver disease and pancreatic disorders can lead to reduced intestinal motility, decreased bile acid synthesis and intestinal immune dysfunction, determining a compositional and functional imbalance in gut microbiota (dysbiosis), with potentially harmful consequences on the host's health. The modulation of the gut microbiota by antibiotics represents a pioneering challenge with striking future therapeutic opportunities, even in non-infectious diseases. In this setting, antibiotics are aimed at harmonizing gut microbial function and, sometimes, composition. A more targeted and specific approach should be the goal to pursue in the future, tailoring the treatment according to the type of microbiota modulation to be achieved and using combined strategies.

Integrative analysis of the gut microbiota and faecal and serum short-chain fatty acids and tryptophan metabolites in patients with cirrhosis and hepatic encephalopathy. J Transl Med 2023; 21:395. [PMID: 37330571 PMCID: PMC10276405 DOI: 10.1186/s12967-023-04262-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/25/2023] [Accepted: 06/09/2023] [Indexed: 06/19/2023] Open
Abstract
OBJECTIVE The purpose of this study was to describe the changes in the gut microbiome of patients with cirrhosis and hepatic encephalopathy (HE), as well as quantify the variations in short-chain fatty acid (SCFA) and tryptophan metabolite levels in serum and faeces. METHODS Fresh faeces and serum were collected from 20 healthy volunteers (NC group), 30 cirrhosis patients (Cir group), and 30 HE patients (HE group). Then, 16S rRNA sequencing and metabolite measurements were performed using the faeces. Gas chromatography‒mass spectrometry and ultrahigh-performance liquid chromatography-tandem mass spectrometry were used to measure SCFA and tryptophan levels, respectively. The results were analysed by SIMCA16.0.2 software. Differences in species were identified using MetaStat and t tests. The correlations among the levels of gut microbes and metabolites and clinical parameters were determined using Spearman correlation analysis. RESULTS Patients with cirrhosis and HE had lower microbial species richness and diversity in faeces than healthy volunteers; these patients also had altered β-diversity. Serum valeric acid levels were significantly higher in the HE group than in the Cir group. Serum SCFA levels did not differ between the Cir and NC groups. Serum melatonin and 5-HTOL levels were significantly higher in the HE group than in the Cir group. The Cir and NC groups had significant differences in the levels of eight serum tryptophan metabolites. Furthermore, the levels of faecal SCFAs did not differ between the HE and Cir groups. Faecal IAA-Ala levels were significantly lower in the HE group than in the Cir group. There were significant differences in the levels of 6 faecal SCFAs and 7 faecal tryptophan metabolites between the Cir and NC groups. Certain gut microbes were associated with serum and faecal metabolites, and some metabolites were associated with certain clinical parameters. CONCLUSION Reduced microbial species richness and diversity were observed in patients with HE and cirrhosis. In both serum and faeces, the levels of different SCFAs and tryptophan metabolites showed varying patterns of change. In HE patients, the levels of some serum tryptophan metabolites, and not SCFAs, were correlated with liver function and systemic inflammation. Systemic inflammation in patients with cirrhosis was correlated with faecal acetic acid levels. In summary, this study identified metabolites important for HE and cirrhosis.

Acute-on-chronic liver failure is independently associated with higher mortality for cirrhotic patients with acute esophageal variceal hemorrhage: Retrospective cohort study. World J Clin Cases 2023; 11:4003-4018. [PMID: 37388802 PMCID: PMC10303600 DOI: 10.12998/wjcc.v11.i17.4003] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/22/2023] [Revised: 04/15/2023] [Accepted: 05/11/2023] [Indexed: 06/12/2023] Open
Abstract
BACKGROUND Acute esophageal variceal hemorrhage (AEVH) is a common complication of cirrhosis and might precipitate multi-organ failure, causing acute-on-chronic liver failure (ACLF).
AIM To analyze if the presence and grading of ACLF as defined by European Society for the Study of the Liver-Chronic Liver Failure (EASL-CLIF) is able to predict mortality in cirrhotic patients presenting AEVH.
METHODS Retrospective cohort study executed in Hospital Geral de Caxias do Sul. Data from medical records from 2010 to 2016 were obtained by searching the hospital electronic database for patients who received terlipressin. Medical records were reviewed in order to determine the diagnosis of cirrhosis and AEVH, including 97 patients. Kaplan-Meier survival analysis was used for univariate analysis and a stepwise approach to the Cox regression for multivariate analysis.
RESULTS All- cause mortality for AEVH patients was 36%, 40.2% and 49.4% for 30-, 90- and 365-day, respectively. The prevalence of ACLF was 41.3%. Of these, 35% grade 1, 50% grade 2 and 15% grade 3. In multivariate analysis, the non-use of non-selective beta-blockers, presence and higher grading of ACLF and higher Model for End-Stage Liver Disease scores were independently associated with higher mortality for 30-day with the addition of higher Child-Pugh scores for 90-day period.
CONCLUSION Presence and grading of ACLF according to the EASL-CLIF criteria was independently associated with higher 30- and 90-day mortality in cirrhotic patients admitted due to AEVH.

Abstract
Cirrhosis transcends various progressive stages from compensation to decompensation driven by the severity of portal hypertension. The downstream effect of increasing portal hypertension severity leads to various pathophysiological pathways, which result in the cardinal complications of cirrhosis, including ascites, variceal hemorrhage, and hepatic encephalopathy. Additionally, the severity of portal hypertension is the central driver for further advanced complications of hyperdynamic circulation, hepatorenal syndrome, and cirrhotic cardiomyopathy. The management of these individual complications has specific nuances which have undergone significant developments. In contrast to the classical natural history of cirrhosis and its complications which follows an insidious trajectory, acute-on-chronic failure (ACLF) leads to a rapidly downhill course with high short-term mortality unless intervened at the early stages. The management of ACLF involves specific interventions, which have quickly evolved in recent years. In this review, we focus on complications of portal hypertension and delve into an approach toward ACLF.

Pre-transjugular-intrahepatic-portosystemic-shunt measurement of hepatic venous pressure gradient and its clinical application: A comparison study. World J Gastroenterol 2023; 29:3519-3533. [PMID: 37389231 PMCID: PMC10303515 DOI: 10.3748/wjg.v29.i22.3519] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/03/2023] [Revised: 03/15/2023] [Accepted: 05/17/2023] [Indexed: 06/06/2023] Open
Abstract
BACKGROUND It is controversial whether transjugular intrahepatic portosystemic shunt (TIPS) placement can improve long-term survival.
AIM To assess whether TIPS placement improves survival in patients with hepatic-venous-pressure-gradient (HVPG) ≥ 16 mmHg, based on HVPG-related risk stratification.
METHODS Consecutive variceal bleeding patients treated with endoscopic therapy + nonselective β-blockers (NSBBs) or covered TIPS placement were retrospectively enrolled between January 2013 and December 2019. HVPG measurements were performed before therapy. The primary outcome was transplant-free survival; secondary endpoints were rebleeding and overt hepatic encephalopathy (OHE).
RESULTS A total of 184 patients were analyzed (mean age, 55.27 years ± 13.86, 107 males; 102 in the EVL+NSBB group, 82 in the covered TIPS group). Based on the HVPG-guided risk stratification, 70 patients had HVPG < 16 mmHg, and 114 patients had HVPG ≥ 16 mmHg. The median follow-up time of the cohort was 49.5 mo. There was no significant difference in transplant-free survival between the two treatment groups overall (hazard ratio [HR], 0.61; 95% confidence interval [CI]: 0.35-1.05; P = 0.07). In the high-HVPG tier, transplant-free survival was higher in the TIPS group (HR, 0.44; 95%CI: 0.23-0.85; P = 0.004). In the low-HVPG tier, transplant-free survival after the two treatments was similar (HR, 0.86; 95%CI: 0.33-0.23; P = 0.74). Covered TIPS placement decreased the rate of rebleeding independent of the HVPG tier (P < 0.001). The difference in OHE between the two groups was not statistically significant (P = 0.09; P = 0.48).
CONCLUSION TIPS placement can effectively improve transplant-free survival when the HVPG is greater than 16 mmHg.

Abstract
Hepatic encephalopathy (HE) is a complex condition that arises as a complication of chronic liver disease and portosystemic shunting. Its pathophysiology involves several factors, including impaired ammonia metabolism, portosystemic shunting, sarcopenia, and systemic inflammation. The symptoms of HE can vary significantly, with manifestations ranging from subclinical signs to a comatose state. The West Haven classification system is most commonly used to grade the severity of HE. There is a broad differential for the presenting symptomatology of HE and other causes of altered mental status must be excluded during the workup. HE is a well-known complication of transjugular intrahepatic portosystemic shunt (TIPS) placement. Even though newer stent designs help reduce the risk of HE with smaller diameter shunts, it is essential that patients are counseled regarding this potential risk prior to the procedure. Once a diagnosis of HE has been confirmed, the mainstay of therapy is lactulose and rifaximin. In cases where a patient has received a TIPS placement and continues to experience refractory HE despite medical therapy, it may be necessary to consider shunt reduction or closure.

Assessment of Serum Zinc Levels in Patients With Decompensated Cirrhosis of the Liver and Its Association With Disease Severity and Hepatic Encephalopathy: A Prospective Observational Study From North India. Cureus 2023; 15:e41207.

Abstract
Background Zinc, an essential trace element, plays a vital role in cellular metabolism, and the liver is the main organ responsible for its metabolism. Because serum zinc levels are found to be lowered in chronic liver diseases, it has been hypothesized to be a precipitating factor for the development of hepatic encephalopathy. Methodology This prospective, observational study included patients with decompensated cirrhosis of the liver who were admitted to the medical intensive care unit of a tertiary care institute in northern India between September 2021 and April 2023. The diagnosis was based on history and detailed clinical examination. The serum zinc levels of patients were estimated using atomic absorption spectrometry at admission and compared to that of healthy controls. Serum zinc levels were correlated with the severity of liver disease and hepatic encephalopathy among the cases. Results A total of 100 cases of decompensated cirrhosis of the liver and 50 healthy controls were included. The mean serum zinc level of the cases was 40.5 ± 10.0 µg/dL which was significantly lower than the mean serum zinc level (104.0±9.1 µg/dL) of controls (p < 0.0001). Serum zinc level was significantly lower in patients with higher grades of hepatic encephalopathy (p = 0.000). Similarly, serum zinc level was significantly reduced among patients with higher Child-Pugh and Model for End-stage Liver Disease scores. Conclusions Serum zinc level is significantly reduced in patients with decompensated cirrhosis of the liver, and lower serum zinc level is associated with the increased severity of the disease and higher grades of hepatic encephalopathy. In patients with decompensated cirrhosis of the liver, maintenance of adequate serum zinc levels may prevent hepatic encephalopathy.
