ABSTRACT
BACKGROUND: Severe alcohol-associated hepatitis (AH) that is nonresponsive to corticosteroids is associated with high mortality, particularly with concomitant acute-on-chronic liver failure (ACLF). Most patients will not be candidates for liver transplantation (LT) and their outcomes are largely unknown. Our aim was to determine the outcomes of these declined candidates and to derive practical prediction models for transplant-free survival applicable at the time of the waitlist decision. METHODS: We analyzed a database of patients with severe AH who were hospitalized at a LT center from January 2012 to July 2021, using the National Death Index for those lacking follow-up. Clinical variables were analyzed based on the endpoints of mortality at 30, 60, 90, and 180 days. Logistic and Cox regression analyses were used for model derivation. RESULTS: Over 9.5 years, 206 patients with severe AH were declined for LT, mostly for unfavorable psychosocial profiles, with a mean MELD of 33 (±8), and 61% with ACLF. Over a median follow-up of 521 (17.5-1368) days, 58% (119/206) died at a median of 21 (9-124) days. Of 32 variables, only age added prognostic value to MELD and ACLF grade. CLIF-C ACLF score and 2 new models, MELD-Age and ACLF-Age, had similar predictability (AUROC: 0.73, 0.73, 0.72, respectively), outperforming Lille and Maddrey's (AUROC: 0.63, 0.62). In internal cross-validation, the average AUROC was 0.74. ACLF grade ≥2, MELD score >35, and age >45 years were useful cutoffs for predicting increased 90-day mortality from waitlist decision. Only two patients initially declined for LT for AH subsequently underwent LT (1%). CONCLUSIONS: Patients with severe AH declined for LT have high short-term mortality and rare rates of subsequent LT. Age added to MELD or ACLF grade enhances survival prediction at the time of waitlist decision in patients with severe AH declined for LT.

INTRODUCTION: During the treatment of alcohol use disorder, alcohol withdrawal syndrome (AWS) can occur. Benzodiazepines remain the "gold standard" for the pharmacological treatment of AWS. However, other drugs have been approved in some European Countries for the treatment of AWS: namely, clomethiazole in Spain and Germany and sodium oxybate in Italy and Austria. Acute alcohol-associated hepatitis (AAH) is a distinct clinical syndrome characterized by the recent onset of jaundice with or without other signs of liver decompensation in patients with ongoing alcohol consumption. RATIONALE: We report 4 paradigmatic clinical cases to analyze the efficacy, safety, and tolerability of the very short half-life (30-45 minutes) sodium oxybate (SO) in the management of AWS with moderate to severe AAH. Compared to SO, "as needed" short-acting benzodiazepines, currently prescribed to treat AWS in patients with AAH, have a much longer half-life (5-25 hours) which increases the risk of drug accumulation. The very short half-life of SO provides a fixed dose approach allowing for a more effective control of AWS than "as needed" therapy throughout the 24 hours. PATIENT CONCERNS: Patients reported anxiety, agitation, diffuse abdominal pain, loss of appetite, and nausea with elevation in serum bilirubin and 2 of them had abdomen distension due to ascites. DIAGNOSIS: Patients were affected by moderate or severe AWS and moderate or severe AAH on alcohol-related liver cirrhosis. INTERVENTIONS: In order to suppress AWS, all patients were treated with oral sodium oxybate at a dose of 25 mg/kg/day, progressively increased to 50 to 100 mg/kg/day, divided into 3 to 5 administrations. OUTCOMES: SO was efficient, safe and tolerable in suppressing AWS even in patients with severe AAH. All treated patients showed a rapid improvement of all symptom (via the Clinical Institute of Withdrawal Assessment for Alcohol Scale) and liver test scores (Model for End-Stage Liver Disease). CONCLUSION: Because of its short half-life, SO can be considered a safe and effective pharmacological option for the AWS in patients with moderate to severe AAH even in comparison to short-acting benzodiazepines, thus avoiding the risk of accumulation. Notably, SO guarantees a fixed approach to cover the possible onset of AWS throughout the 24 hours.

Nonalcoholic steatohepatitis (NASH) and alcoholic hepatitis (AH) affect a large part of the general population worldwide. Dysregulation of lipid metabolism and alcohol toxicity drive disease progression by the activation of hepatic stellate cells and the capillarization of liver sinusoidal endothelial cells. Collagen deposition, along with sinusoidal remodeling, alters sinusoid structure, resulting in hepatic inflammation, portal hypertension, liver failure, and other complications. Efforts were made to develop treatments for NASH and AH. However, the success of such treatments is limited and unpredictable. We report a strategy for NASH and AH treatment involving the induction of integrin αvß3-mediated cell apoptosis using a rationally designed protein (ProAgio). Integrin αvß3 is highly expressed in activated hepatic stellate cells (αHSCs), the angiogenic endothelium, and capillarized liver sinusoidal endothelial cells (caLSECs). ProAgio induces the apoptosis of these disease-driving cells, therefore decreasing collagen fibril, reversing sinusoid remodeling, and reducing immune cell infiltration. The reversal of sinusoid remodeling reduces the expression of leukocyte adhesion molecules on LSECs, thus decreasing leukocyte infiltration/activation in the diseased liver. Our studies present a novel and effective approach for NASH and AH treatment.

BACKGROUND: Alcohol-associated hepatitis (AH) is associated with significant mortality. Model for End-Stage Liver Disease (MELD) score is used to predict short-term mortality and aid in treatment decisions. MELD is frequently updated in the course of AH. However, once the most updated MELD is known, it is uncertain if previous ones still have prognostic value, which might be relevant for transplant allocation and trial design. We aimed to investigate the predictive performance of updated MELDs in a prospectively collected cohort of patients with AH by the InTeam consortium. METHODS: Three hundred seven patients (with 859 MELD values within 60 d of admission) fulfilled the inclusion criteria. The main endpoint was time to death or transplant up to 90 days. We used a joint model approach to assess the predictive value of updated MELDs. RESULTS: Updated MELD measurements had a strong prognostic value for death/transplant (HR: 1.20, 95% CI: 1.14-1.27) (p < 0.0001). Previous MELD values did not add predictive value to the most current MELD. We also showed that MELD at day 28 (MELD28) had a significant predictive value for subsequent mortality/transplant in a landmark analysis (HR: 1.18, 95% CI: 1.12-1.23). We show that the use of an ordinal scale including death, transplant, and MELD28 as a trial outcome could substantially reduce the sample size required to demonstrate short-term benefit of an intervention. CONCLUSION: We show that updated MELDs during the trajectory of AH predict subsequent mortality or the need for transplant. MELD28 inclusion in an ordinal outcome (together with death or transplant) could increase the efficiency of randomized controlled trials.

Severe Alcoholic Hepatitis (sAH) is an acute form of liver injury caused by chronic and heavy alcohol drinking. A one-month corticosteroids course is the only sAH reference treatment, and its interactions with the Gut Microbiota (GM), which is a key contributor to liver injury, remain unknown. To evaluate the evolution of the GM in sAH patients, we retrospectively investigated the composition of the GM of 27 sAH patients at the Amiens University Hospital before (D0) and after (D7) a 7-day corticotherapy course using fecal metagenomics sequencing. We also quantified fecal Short-Chain Fatty Acids (SCFA) and fecal and serum Bile Acids (BA), as well as serum Lipopolysaccharide-Binding Protein (LBP). Overall, the community and taxonomical analyses did not reveal any GM evolution between D0 and D7, nor did the SCFA profiles analysis. However, in serum but not fecal samples, the ratio of glyco-conjugated to tauro-conjugated BA was significantly reduced at D7, independently of the response to treatment, while two BA were enriched in non-responder patients. LBP concentration significantly diminished between D0 and D7, which may indicate an improvement of the gut barrier. The stability of the GM of sAH is interesting in the perspective of new treatments based on GM modulation.
There is a gap in the understanding of the effects of corticosteroids on the gut microbiota of severe alcoholic hepatitis patients.In this study, the composition of the Gut Microbiota of sAH patients treated with prednisolone remains unchanged after 7 days of prednisolone treatment.Short-Chain Fatty Acid profiles are not impacted by the treatment, while Bile Acids profiles change in serum but not in stool samples.Responders and non-responders show different lipopolysaccharide-binding protein serum concentration evolution across time, as well as distinct Bile Acid profiles.

BACKGROUND: Alcohol-associated hepatitis (AH) is plagued with high mortality and difficulty in identifying at-risk patients. The extracellular matrix undergoes significant remodeling during inflammatory liver injury and could potentially be used for mortality prediction. METHODS: EDTA plasma samples were collected from patients with AH (n = 62); Model for End-Stage Liver Disease score defined AH severity as moderate (12-20; n = 28) and severe (>20; n = 34). The peptidome data were collected by high resolution, high mass accuracy UPLC-MS. Univariate and multivariate analyses identified differentially abundant peptides, which were used for Gene Ontology, parent protein matrisomal composition, and protease involvement. Machine-learning methods were used to develop mortality predictors. RESULTS: Analysis of plasma peptides from patients with AH and healthy controls identified over 1600 significant peptide features corresponding to 130 proteins. These were enriched for extracellular matrix fragments in AH samples, likely related to the turnover of hepatic-derived proteins. Analysis of moderate versus severe AH peptidomes was dominated by changes in peptides from collagen 1A1 and fibrinogen A proteins. The dominant proteases for the AH peptidome spectrum appear to be CAPN1 and MMP12. Causal graphical modeling identified 3 peptides directly linked to 90-day mortality in >90% of the learned graphs. These peptides improved the accuracy of mortality prediction over the Model for End-Stage Liver Disease score and were used to create a clinically applicable mortality prediction assay. CONCLUSIONS: A signature based on plasma peptidome is a novel, noninvasive method for prognosis stratification in patients with AH. Our results could also lead to new mechanistic and/or surrogate biomarkers to identify new AH mechanisms.

BACKGROUND & AIMS: Severe alcohol-associated hepatitis (SAH) represents a lethal subset of alcohol-associated liver disease. Although corticosteroids are recommended by guidelines, their efficacy and safety remain questionable and so liver transplantation (LT) has been increasingly utilized. The timing and indication of corticosteroid use, specifically in patients being considered for LT requires further clarification. METHODS: A retrospective analysis was conducted on 256 patients with SAH between 2018 and 2022 at a single US center. RESULTS: Twenty of these patients underwent LT. Of the 256 patients, 38% had what we termed "catastrophic" SAH, defined as a MELD-Na ≥35 and/or discriminant function (DF) ≥100, which carried a mortality of 90% without LT. Compared with 100 matched controls, patients undergoing LT exhibited a one-year survival rate of 100% versus 35% (p < .0005). LT provided an absolute risk reduction of 65%, with a number needed to treat of 1.5. Steroid utilization in the entire cohort was 19% with 60% developing severe complications. Patients administered steroids were younger with lower MELD and DF scores. Only 10% of those prescribed steroids derived a favorable response. Sustained alcohol use post-LT was 20%. CONCLUSIONS: We propose ELFSAH: Expedited LT as First Line Therapy for SAH; challenging the current paradigm with recommendations to defer steroids in patients with "catastrophic" SAH (defined as: MELD-Na ≥35 and/or DF ≥100). Patients should be seen urgently by hepatology, transplant surgery, psychiatry and social work. Patients without an absolute contraindication should be referred for LT as first-line therapy during their index admission.

BACKGROUND: The recent increase in the incidence of alcohol-associated hepatitis (AH) coincides with the obesity epidemic in the United States. However, current mouse models do not fully replicate the combined insults of obesity, metabolic dysfunction-associated steatohepatitis, and alcohol. The aim of this study was to develop a new mouse model that recapitulates the robust inflammatory and fibrotic phenotype characteristic of human MetALD. METHODS: Eight- to 10-week-old male C57BL/6 mice were fed chow or high fat-cholesterol-sugar diet (metabolic dysfunction-associated steatohepatitis diet) and in each group, some received alcohol in drinking water (ad libitum) and weekly alcohol binges (EtOH) for 3 months. The liver was assessed for features of AH. RESULTS: MetALD mice displayed increased liver damage indicated by highly elevated ALT and bilirubin levels compared to all other groups. Liver steatosis was significantly greater in the MetALD mice compared to all other experimental groups. The inflammatory phenotype of MetALD was also recapitulated, including increased IL-6 and IL-1ß protein levels as well as increased CD68+ macrophages and Ly6G+ neutrophils in the liver. Sirius red staining and expression of collagen 1, alpha-smooth muscle actin indicated advanced fibrosis in the livers of MetALD mice. In addition, indicators of epithelial-to-mesenchymal transition markers were increased in MetALD mice compared to all other groups. Furthermore, we found increased ductular reaction, dysregulated hedgehog signaling, and decreased liver synthetic functions, consistent with severe AH. CONCLUSIONS: Alcohol administration in mice combined with metabolic dysfunction-associated steatohepatitis diet recapitulates key characteristics of human AH including liver damage, steatosis, robust systemic inflammation, and liver immune cell infiltration. This model results in advanced liver fibrosis, ductular reaction, decreased synthetic function, and hepatocyte dedifferentiation, suggesting a robust model of MetALD in mice.

BACKGROUND/AIMS: In alcohol-associated hepatitis (AH), the Lille score is used to assess futility of steroids. However, the ability of the Lille score to predict 30-day survival in AH is not well-defined. Our aim is to compare the utility of the Lille score in predicting 30-day survival in those with AH treated with steroids. METHODS: Retrospective chart review of 882 patients hospitalized with AH from January 1st, 2012 through December 30th, 2019 was performed. Of these, 201 patients with severe AH met the threshold to receive steroids. Those with data to calculate Lille score < 0.45 on day 4 (n = 29) or 7 (n = 89) who continued steroids were compared to 83 patients with Lille scores ≥ 0.45 on day 4 (n = 18) or 7 (n = 65) who stopped steroids. The primary outcome was 30-day survival. For comparison, a contemporaneous matched control group was also analyzed of 110 patients who were hospitalized with severe AH, but did not receive steroids. RESULTS: In patients with Lille score < 0.45, survival was higher at 30-day when compared to those with Lille score ≥ 0.45 (94.9% vs. 80.72%; p = 0.002). The sensitivity, specificity, positive predictive value and negative predictive value of Lille score (< 0.45) to predict 30-day survival was 95%, 19%, 63%, and 73%, respectively. CONCLUSIONS: In severe AH, those with Lille score < 0.45 at day 4 or 7 have improved 30-day survival compared to those with Lille score ≥ 0.45. In those receiving steroids, Lille score has excellent sensitivity to predict 30-day survival but poor specificity.

Neutrophil infiltration occurs in a variety of liver diseases, but it is unclear how neutrophils and hepatocytes interact. Neutrophils generally use granule proteases to digest phagocytosed bacteria and foreign substances or neutralize them in neutrophil extracellular traps. In certain pathological states, granule proteases play a destructive role against the host as well. More recently, nondestructive actions of neutrophil granule proteins have been reported, such as modulation of tissue remodeling and metabolism. Here, we report a completely different mechanism by which neutrophils act nondestructively, by inserting granules directly into hepatocytes. Specifically, elastase-containing granules were transferred to hepatocytes where elastase selectively degraded intracellular calcium channels to reduce cell proliferation without cytotoxicity. In response, hepatocytes increased expression of Serpin E2 and A3, which inhibited elastase activity. Elastase insertion was seen in patient specimens of alcohol-associated hepatitis, and the relationship between elastase-mediated ITPR2 degradation and reduced cell proliferation was confirmed in mouse models. Moreover, neutrophils from patients with alcohol-associated hepatitis were more prone to degranulation and more potent in reducing calcium channel expression than neutrophils from healthy individuals. This nondestructive and reversible action on hepatocytes defines a previously unrecognized role for neutrophils in the transient regulation of epithelial calcium signaling mechanisms.

Alcohol-associated hepatitis (AH) is an acute-on-chronic liver injury that occurs in patients with chronic alcohol-associated liver disease (ALD). Patients with severe AH have high short-term mortality and lack effective pharmacologic therapies. Inflammation is believed to be one of the key factors promoting AH progression and has been actively investigated as therapeutic targets over the last several decades, but no effective inflammatory targets have been identified so far. In this review, we discuss how inflammatory cells and the inflammatory mediators produced by these cells contribute to the development and progression of AH, with focus on neutrophils and macrophages. The crosstalk between inflammatory cells and liver nonparenchymal cells in the pathogenesis of AH is elaborated. We also deliberate the application of recent cutting-edge technologies in characterizing liver inflammation in AH. Finally, the potential therapeutic targets of inflammatory mediators for AH are briefly summarized.

INTRODUCTION: Alcoholic hepatitis (AH) is a serious complication of alcohol consumption with high morbidity and mortality, particularly in the United States where alcohol-related liver diseases rank as one of the leading causes of preventable death. Our study aims to analyze the morbidity and mortality of AH across racial groups and project hospitalization trends up to 2028, thereby informing public health initiatives. METHODS: We conducted a cross-sectional study utilizing data from the Nationwide Inpatient Sample (NIS) spanning 2012 to 2021. The study population comprised hospitalizations identified using specific ICD-9-CM and ICD-10-CM codes for AH. We assessed hospitalizations, in-hospital mortality rates, length of stay (LOS), and morbidities related to alcoholic hepatitis adjusting for sociodemographic factors and hospital characteristics. Statistical analyses were performed using Stata and R software, employing logistic and linear regression analyses, and SARIMA models for forecasting. RESULTS: Our results indicated a predominantly White cohort (68%), with a notable increase in AH hospitalizations among Hispanics (129.1% from 2012 to 2021). Racial disparities were observed in inpatient mortality, liver transplant accessibility, and the occurrence of in-hospital complications. The study forecasts a continued rise in hospitalizations across all racial groups, with Hispanics experiencing the sharpest increase. CONCLUSION: Our study reveals a disproportionate rise in the AH burden among Hispanics with projections indicating a persistent upward trend through 2028. These findings highlight the need for targeted public health strategies and improved healthcare access to mitigate the increasing AH burden and address disparities in care and outcomes.

While steroid therapy is the preferred treatment for severe alcohol-associated hepatitis, the role of effector regulatory T (eTreg) cells and their association with steroid response and clinical outcomes in these patients remains to be elucidated. We prospectively enrolled 47 consecutive patients with alcohol-associated hepatitis, consisting of severe alcohol-associated hepatitis treated with steroids (n=18; steroid-treated group) and mild alcohol-associated hepatitis (n=29; nontreated group). After isolating peripheral blood mononuclear cells from the patients at enrollment and again 7 days later, the frequency of eTreg cells was examined using flow cytometry. Single-cell RNA sequencing analysis was conducted using paired peripheral blood mononuclear cells. In vitro experiments were also performed to assess phenotype changes and the suppressive function of Treg cells following steroid treatment. The steroid-treated group exhibited significantly higher Model for End-Stage Liver Disease scores than the nontreated group ( p < 0.01). Within the steroid-treated group, the proportion of eTreg cells significantly expanded in the steroid responders (n=13; p = 0.01). Furthermore, a significant positive correlation was observed between the decrease in the Model for End-Stage Liver Disease score and the increase in eTreg cells ( p < 0.05). Single-cell RNA sequencing using paired peripheral blood mononuclear cells (pre-steroid and post-steroid therapy) from a steroid responder revealed gene expression changes in T cells and monocytes, suggesting enhancement of Treg cell function. In vitro results showed an elevation in the proportion of eTreg cells after steroid therapy. In conclusion, our findings suggest that the efficacy of steroid therapy in patients with severe alcohol-associated hepatitis is mediated by an increase in the number of eTreg cells.

BACKGROUND AND OBJECTIVES: Transfusion-related acute lung injury is an infrequent adverse reaction observed in patients receiving blood products. The lung injury can range in severity and can be associated with both mortality and mortality. All blood products except albumin have been linked to cases of transfusion-related acute lung injury. In fact, albumin may be used as a salvage modality in severe transfusion-related acute lung injury. We report an alcoholic patient who developed lung injury following treatment with albumin in the setting of hypoalbuminaemia. MATERIALS AND METHODS: A 41-year-old male with alcoholic liver disease was admitted for severe ascites and alcoholic hepatitis. Chest x-ray showed small pleural effusions at the lung bases with no overt pulmonary oedema. He received high doses of furosemide for lower extremity oedema. The patient received a total of two albumin infusions to augment the diuresis effect. RESULTS: He subsequently developed acute hypoxic respiratory failure with imaging showing interstitial and airspace abnormalities concerning for pulmonary oedema. He showed no additional signs of volume overload and was treated supportively until the condition improved. CONCLUSION: This is the first reported case of albumin-associated lung injury proximally related to albumin infusion. We aim to increase awareness of this possible sequelae among physicians.

Diagnostic challenges continue to impede development of effective therapies for successful management of alcohol-associated hepatitis (AH), creating an unmet need to identify noninvasive biomarkers for AH. In murine models, complement contributes to ethanol-induced liver injury. Therefore, we hypothesized that complement proteins could be rational diagnostic/prognostic biomarkers in AH. Here, we performed a comparative analysis of data derived from human hepatic and serum proteome to identify and characterize complement protein signatures in severe AH (sAH). The quantity of multiple complement proteins was perturbed in liver and serum proteome of patients with sAH. Multiple complement proteins differentiated patients with sAH from those with alcohol cirrhosis (AC) or alcohol use disorder (AUD) and healthy controls (HCs). Serum collectin 11 and C1q binding protein were strongly associated with sAH and exhibited good discriminatory performance among patients with sAH, AC, or AUD and HCs. Furthermore, complement component receptor 1-like protein was negatively associated with pro-inflammatory cytokines. Additionally, lower serum MBL associated serine protease 1 and coagulation factor II independently predicted 90-day mortality. In summary, meta-analysis of proteomic profiles from liver and circulation revealed complement protein signatures of sAH, highlighting a complex perturbation of complement and identifying potential diagnostic and prognostic biomarkers for patients with sAH.

ABSTRACT: Alcoholic hepatitis is a form of inflammation of the liver caused by alcohol use. Data on the best treatment are conflicting. Treatment guidelines include the use of prednisolone and supportive care, although this is controversial. This article reviews the guidelines for treating alcoholic hepatitis and current recommendations.

Alcohol-related liver disease (ALD) represents the most common indication for liver transplantation (LT) worldwide. Outcomes of LT for ALD are comparable with those of LT for other etiologies; however, ALD is still considered a controversial indication for LT, mainly because it is considered a self-inflicted disease with a high risk of return to alcohol use after LT. Pre-LT evaluation criteria have changed over time, with a progressive re-evaluation of the required pre-transplant duration of abstinence. Despite the fact that some transplant programs still require 6 months of abstinence in order to consider a patient suitable for LT, there is increasing evidence that a pre-transplant abstinence period of <6 months can be considered for well-selected patients. Early LT for severe alcohol-related hepatitis that has not responded to medical therapy has been shown to be an effective therapeutic option with high survival benefit when performed within strict and well-recognized criteria. However, high variability in LT access exists for these patients due to the presence of social and medical stigma. A psycho-social assessment, together with an evaluation by an addiction specialist, should be mandatory in patients with ALD who are potential candidates for LT in order to assess the risk of post-transplant return to alcohol use and to ensure good long-term outcomes. Finally, before LT, attention should be paid to the presence of other potential comorbidities (i.e., cardiovascular and neurological diseases), which could represent a potential contraindication to LT. Similarly, after LT, patients should be adequately monitored for the development of cardiovascular events and screened for "de novo" tumors, although standardized protocols for this monitoring do not exist at this time.
