- Abstract
Liver is the most common organ affected by alcohol misuse. The spectrum of alcohol-associated liver disease (ALD) ranges from simple steatosis to cirrhosis and its complications. The unique clinical phenotype of alcohol-associated hepatitis has a risk for high short-term mortality. Several gaps exist with respect to epidemiology, noninvasive testing, prognostication, and treatment of ALD. Most studies focus on short-term survival as the ideal endpoint and ignore other aspects of alcohol-use disorder and ALD. In this review, the authors discuss the existing knowledge gaps, enumerate ongoing clinical trials, and highlight the research priorities and future landscape of clinical trials., Competing Interests: Disclosure None., (Copyright © 2024 Elsevier Inc.

- Abstract
Background: Outcomes in alcohol-associated liver disease (ALD) are influenced by several race and ethnic factors, yet its natural history across the continuum of patients in different stages of the disease is unknown., Methods: We conducted a retrospective cohort study of U.S. adults from 2011 to 2018, using three nationally representative databases to examine potential disparities in relevant outcomes among racial and ethnic groups. Our analysis included logistic and linear regressions, along with competing risk analysis., Results: Black individuals had the highest daily alcohol consumption (12.6 g/day) while Hispanic participants had the largest prevalence of heavy episodic drinking (33.5%). In a multivariable-adjusted model, Hispanic and Asian participants were independently associated with a higher ALD prevalence compared to Non-Hispanic White interviewees (OR: 1.4, 95% CI: 1.1-1.8 and OR: 1.5 95% CI:1.1-2.0, respectively), while Blacks participants had a lower ALD prevalence (OR: .7 95% CI: .6-.9), and a lower risk of mortality during hospitalization due to ALD (OR: .83 95% CI: .73-.94). Finally, a multivariate competing-risk analysis showed that Hispanic ethnicity had a decreased probability of liver transplantation if waitlisted for ALD (SHR: .7, 95% CI: .6-.8) along with female Asian population (HR: .40, 95% CI: .26-.62)., Conclusions: After accounting for key social and biological health determinants, the Hispanic population showed an increased risk of ALD prevalence, even with lower alcohol consumption. Additionally, Hispanic and Asian female patients had reduced access to liver transplantation compared to other enlisted patients., (© 2024 The Author(s).

- Abstract
Background and Aims: Myokines are the muscle-derived hormones orchestrating muscle and systemic health. Their role in the progression of alcohol-associated liver disease (ALD) remains elusive., Methods: Three-hundred-one patients across the spectrum of ALD including fatty liver (FL, N = 13), compensated cirrhosis (CC, N = 17), non-acute decompensation (NAD, N = 95), acute decompensation (AD, N = 51) and acute-on-chronic liver failure (ACLF, N = 125) were recruited between 2021 and 2023. Plasma myostatin, decorin levels, nutritional status, handgrip strength (HGS), systemic inflammation, infection, ammonia, disease course and 30-day mortality were recorded., Results: Patients aged 48 years (IQR: 38-52) and 97.7% of males were enrolled. Myostatin was elevated while decorin was reduced in cirrhosis compared to without cirrhosis, and further in DC compared to CC (p < 0.001). A step-wise increase in myostatin and reduction in decorin was observed transitioning from NAD to AD to ACLF (p < 0.001). Myostatin was further increased and decorin was reduced along with the grades and organ failures in AD and ACLF (p < 0.001, each). Baseline decorin (AUC: 0.797) and its combination with MELD (AUC: 0.814) predicted disease resolution in AD and ACLF. Although, both myostatin (aOR: 18.96) and decorin (aOR: 0.02) could predict mortality, decorin was independent (aOR: 0.04) and additive to MELD (AUC of MELD+
log Decorin +log TLC + HE-grade:0.815); p < 0.05 each. Myostatin increased and decorin reduced with inflammation, hyperammonaemia, malnutrition and HGS in AD and ACLF (p < 0.05, each)., Conclusion: Myokines are linked with malnutrition, fibrosis, systemic inflammation, organ failures, disease course and mortality in ALD. Decorin enhances the risk estimation of mortality of MELD in AD and ACLF. Therapeutic modulation of myokines is a potentially disease-modifying target in ALD., (© 2024 John Wiley & Sons Ltd.)- Published

- Abstract
Most patients with alcohol-associated liver disease (ALD) engage in heavy drinking defined as 4 or more drinks per day (56 g) or 8 (112 g) or more drinks per week for women and 5 or more drinks per day (70 g) or 15 (210 g) or more drinks per week for men. Although abstinence from alcohol after diagnosis of ALD improves life expectancy and reduces the risk of decompensation of liver disease, few studies have evaluated whether treatment of alcohol use disorders will reduce progression of liver disease and improve liver-related outcomes. In November 2021, the National Institute of Alcohol Abuse and Alcoholism commissioned a task force that included hepatologists, addiction medicine specialists, statisticians, clinical trialists and members of regulatory agencies to develop recommendations for the design and conduct of clinical trials to evaluate the effect of alcohol use, particularly treatment to reduce or eliminate alcohol use in patients with ALD. The task force conducted extensive reviews of relevant literature on alcohol use disorders and ALD. Findings were presented at one in-person meeting and discussed over the next 16 months to develop the final recommendations. As few clinical trials directly address this topic, the 28 recommendations approved by all members of the task force represent a consensus of expert opinions., (© 2024. Springer Nature Limited.)

- Abstract
Alcohol use is the most important determinant of the development of alcohol-associated liver disease (ALD) and of predicting long-term outcomes in those with established liver disease. Worldwide, the amount, type, and pattern of use of alcohol vary. Alcohol use and consequent liver disease have been increasing in certain ethnic groups especially Hispanics and Native Americans, likely due to variations in genetics, cultural background, socio-economic status, and access to health care. Furthermore, the magnitude and burden of ALD have been increasing especially in the last few years among females and young adults who are at the prime of their productivity. It is critical to recognize the problem and care for these patients integrating cultural aspects in liver clinics. At the federal level, a societal approach is needed with the implementation of public health policies aiming to reduce alcohol consumption in the community. By addressing these challenges and promoting awareness, we can strive to reduce the burden of ALD, especially in high-risk demographic groups to improve their long-term health outcomes. Finally, we need studies and quality research examining these changing landscapes of demographics in ALD as a basis for developing therapeutic targets and interventions to reduce harmful drinking behaviours in these high-risk demographic groups., (© 2024 John Wiley & Sons A/S.

- Abstract
Background & Aims: The long-term impact of alcohol-related public health policies (PHPs) on disease burden is unclear. We aimed to assess the association between alcohol-related PHPs and alcohol-related health consequences., Methods: We conducted an ecological multi-national study including 169 countries. We collected data on alcohol-related PHPs from the WHO Global Information System of Alcohol and Health 2010. Data on alcohol-related health consequences between 2010-2019 were obtained from the Global Burden of Disease database. We classified PHPs into five items, including criteria for low, moderate, and strong PHP establishment. We estimated an alcohol preparedness index (API) using multiple correspondence analysis (0 lowest and 100 highest establishment). We estimated an incidence rate ratio (IRR) for outcomes according to API using adjusted multilevel generalized linear models with a Poisson family distribution., Results: The median API in the 169 countries was 54 [IQR 34.9-76.8]. The API was inversely associated with alcohol use disorder (AUD) prevalence (IRR 0.13; 95% CI 0.03-0.60; p = 0.010), alcohol-associated liver disease (ALD) mortality (IRR 0.14; 95% CI 0.03-0.79; p = 0.025), mortality due to neoplasms (IRR 0.09; 95% CI 0.02-0.40; p = 0.002), alcohol-attributable hepatocellular carcinoma (HCC) (IRR 0.13; 95% CI 0.02-0.65; p = 0.014), and cardiovascular diseases (IRR 0.09; 95% CI 0.02-0.41; p = 0.002). The highest associations were observed in the Americas, Africa, and Europe. These associations became stronger over time, and AUD prevalence was significantly lower after 2 years, while ALD mortality and alcohol-attributable HCC incidence decreased after 4 and 8 years from baseline API assessment, respectively (p <0.05)., Conclusions: The API is a valuable instrument to quantify the robustness of alcohol-related PHP establishment. Lower AUD prevalence and lower mortality related to ALD, neoplasms, alcohol-attributable HCC, and cardiovascular diseases were observed in countries with a higher API. Our results encourage the development and strengthening of alcohol-related policies worldwide., Impact and Implications: We first developed an alcohol preparedness index, an instrument to assess the existence of alcohol-related public policies for each country. We then evaluated the long-term association of the country's alcohol preparedness index in 2010 with the burden of chronic liver disease, hepatocellular carcinoma, other neoplasms, and cardiovascular disease. The strengthening of alcohol-related public health policies could impact long-term mortality rates from cardiovascular disease, neoplasms, and liver disease. These conditions are the main contributors to the global burden of disease related to alcohol use. Over time, this association has not only persisted but also grown stronger. Our results expand the preliminary evidence regarding the importance of public health policies in controlling alcohol-related health consequences., (Copyright © 2023 The Author(s).

- Abstract
Alcohol-associated liver disease (ALD) has emerged as the leading indication for liver transplantation (LT) worldwide, with 40% of LTs in the United States performed for ALD in 2019. The ALD-related health care burden accelerated during the COVID-19 pandemic, especially in young individuals. Alcohol use disorder (AUD), which focuses on the negative effects of alcohol on psychosocial, physical, and mental health, is present in the majority of patients with ALD, with moderate to severe AUD in 75%-80%. During the last decade, early liver transplantation (eLT) has emerged as a lifesaving treatment for selected patients with alcohol-associated hepatitis; these patients may have a higher risk of using alcohol after LT. The risk of alcohol use recurrence may be reduced during the pretransplant or post-transplant period with AUD treatment using behavioral and/or pharmacological therapies and with regular monitoring for alcohol use (self-reported and complemented with biomarkers like phosphatidylethanol). However, AUD treatment in patients with ALD is challenging due to patient, clinician, and system barriers. An integrated model to provide AUD and ALD care by hepatologists and addiction experts in a colocated clinic starting from LT evaluation and selection to monitoring listed candidates and then to following up on recipients of LT should be promoted. However, the integration of addiction and hepatology teams in an LT program in the real world is often present only during evaluation and candidate selection for LT. Data are emerging to show that a multidisciplinary integrated AUD treatment within an LT program reduces recurrent alcohol use after LT. If we want to continue using early liver transplantation for patients with severe alcohol-associated hepatitis, LT programs should focus on building integrated multidisciplinary care teams for the integrated treatment of both AUD and ALD., (Copyright © 2023 American Association for the Study of Liver Diseases.)

- Abstract
Abstract: Alcohol-associated liver disease (ALD) is the most common cause of advanced hepatic disease and frequent indication for liver transplantation worldwide. With harmful alcohol use as the primary risk factor, increasing alcohol use over the past decade has resulted in rapid growth of the ALD-related healthcare burden. The spectrum of ALD ranges from early asymptomatic liver injury to advanced disease with decompensation and portal hypertension. Compared with those with other etiologies of liver disease, patients with ALD progress faster and more often present at an advanced stage. A unique phenotype of advanced disease is alcohol-associated hepatitis (AH) presenting with rapid onset or worsening of jaundice, and acute on chronic liver failure in severe forms conveying a 1-month mortality risk of 20%-50%. The model for end stage disease score is the most accurate score to stratify AH severity (>20 defined as severe disease). Corticosteroids are currently the only available therapeutic with proven efficacy for patients with severe AH, providing survival benefit at 1 month in 50%-60% of patients. Abstinence of alcohol use, a crucial determinant of long-term outcomes, is challenging to achieve in ALD patients with concurrent alcohol use disorder (AUD). As patients with ALD are rarely treated for AUD, strategies are needed to overcome barriers to AUD treatment in patients with ALD and to promote a multidisciplinary integrated care model with hepatology, addiction medicine providers, and social workers to comprehensively manage the dual pathologies of liver disease and of AUD. Liver transplantation, a definitive treatment option in patients with advanced cirrhosis, should be considered in selected patients with AH, who are unresponsive to medical therapy and have a low risk of relapse to posttransplant alcohol use. Level of evidence and strength of recommendations were evaluated using the Grading of Recommendations, Assessment, Development, and Evaluations system. This guideline was developed under the American College of Gastroenterology Practice Parameters Committee., (Copyright © 2024 by The American College of Gastroenterology.)

- Abstract
Alcoholic hepatitis (AH) is a unique clinical syndrome on the spectrum of alcohol-associated liver disease (ALD). It constitutes a rising epidemic with increasing incidence and major public health implications. In severe AH, 30-day mortality approaches 30%, yet therapeutic options remain limited. Survival benefit from corticosteroids, the mainstay of medical treatment, is short-lived. Among corticosteroid nonresponders, the use of early liver transplantation is heterogeneous across centers and remains limited by significant barriers. Long-term prognosis is largely dictated by abstinence; however, comorbid alcohol use disorder remains undertreated. Efforts to address these challenges are required to curb the AH epidemic., (Copyright © 2022 Elsevier Inc. All rights reserved.)

- Abstract
Alcohol-associated liver disease is a leading cause of mortality and morbidity worldwide. Patients with alcohol-associated liver disease are often diagnosed at advanced stage and disease spectrum including alcoholic hepatitis, a severe manifestation with a high short-term mortality. Corticosteroid, recommended first-line treatment for patients with alcoholic hepatitis, is a very suboptimal treatment. Although the use of early liver transplantation has increased with consistent benefit in select patients with alcoholic hepatitis, its use remains heterogeneous worldwide due to lack of uniform selection criteria. Over the last decade, several therapeutic targets have evolved of promise with ongoing clinical trials in patients with cirrhosis and alcoholic hepatitis. Even with availability of effective medical therapies for alcohol-associated liver disease, long-term outcome depends on abstinence from alcohol use in any spectrum of alcohol-associated liver disease. However, alcohol use disorder treatment remains underutilized due to several barriers even in patients with advanced disease. There is an urgent unmet need to implement and promote integrated multidisciplinary care model with hepatologists and addiction experts to provide comprehensive management for these patients. In this review, we will discuss newer therapies targeting liver disease and therapies targeting alcohol use disorder in patients with alcohol-associated liver disease., Competing Interests: Disclosure The authors report no conflicts of interest in this work., (Thieme.

- Abstract
The COVID-19 pandemic is having substantial impacts on the health status of individuals with alcohol use disorder (AUD) and alcohol-associated liver disease (ALD). AUD and ALD have both been impacted throughout the pandemic, with increases in alcohol use during the early stages of the pandemic, reduced access to treatment during the mid-pandemic, and challenges in managing the downstream effects in the post-COVID era. This review will focus on how the COVID-19 pandemic has impacted AUD and ALD epidemiology and access to treatment, and will discuss to address this rising AUD and ALD disease burden., Competing Interests: Conflict of interest SDL is supported in part by NIH grant T32 DK007634.

- Abstract
Alcohol-associated liver disease (ALD) is emerging worldwide as the leading cause of liver-related morbidity, mortality, and indication for liver transplantation. The ALD Special Interest Group and the Clinical Research Committee at the digital American Association for the Study of Liver Diseases meeting in November 2020 held the scientific sessions to identify clinical unmet needs in ALD, and addressing these needs using clinical research methodologies. Of several research methodologies, the sessions were focused on (a) studying disease burden of ALD using large administrative databases, (b) developing biomarkers for noninvasive diagnosis of alcohol-associated hepatitis (AH) and estimation of disease prognosis, (c) identifying therapeutic targets for ALD and AH, (d) deriving accurate models to predict prognosis or posttransplant alcohol relapse as a basis for developing treatment algorithm and a uniform protocol on patient-selection criteria for liver transplantation, and (e) examining qualitative research methodologies in studying the barriers to implementation of multidisciplinary integrated care model by hepatology and addiction teams for the management of dual pathology of liver disease and of alcohol use disorder. Prospective multicenter studies are required to address many of these clinical unmet needs. Further, multidisciplinary care models are needed to improve long-term outcomes in patients with ALD., (© 2021 American Association for the Study of Liver Diseases.)

- Abstract
Despite its increased recognition as a major public health issue, alcohol use disorder is mostly underdiagnosed and undertreated. The undertreatment and underdiagnosis of alcohol use disorder is most concerning in the management of patients with alcohol-associated liver disease, which is one of the main medical consequences of chronic and excessive alcohol use. Dual pathology (alcohol use disorder and alcohol-associated liver disease) requires multidisciplinary care involving hepatologists and addiction specialists. Such integrated care models are widely accepted as optimal care for treating comorbid medical and mental health conditions. However, the implementation of such models in clinical practice is challenging and often represents the exception, rather than the rule, in managing patients with alcohol use disorder and alcohol-associated liver disease. Barriers at the patient, clinician, and system levels are encountered in treating patients with alcohol use disorder and alcohol-associated liver disease. In this Viewpoint, we synthesise the emerging literature on the potential barriers encountered in caring for patients with alcohol-associated liver disease and alcohol use disorder and focus on how integrated models of care could overcome these barriers. We provide our perspective on why these barriers exist and propose strategies to overcome them., Competing Interests: Declaration of interests LL reports honoraria from the UK Medical Council on Alcoholism (Editor-in-Chief for Alcohol and Alcoholism); receives book royalties from Routledge; funding from the Intramural Research Program of the National Institute on Drug Abuse and the National Institute on Alcohol Abuse and Alcoholism (ZIA-DA000635 and ZIA-AA000218); and employment by the National Institutes of Health.

- Abstract
Background and Aims: Alcohol-associated liver disease (ALD) is the leading cause of liver-related mortality in Latin America, yet the impact of public health policies (PHP) on liver disease is unknown. We aimed to assess the association between alcohol PHP and deaths due to ALD in Latin American countries., Approach and Results: We performed an ecological multinational study including 20 countries in Latin America (628,466,088 inhabitants). We obtained country-level sociodemographic information from the World Bank Open Data source. Alcohol-related PHP data for countries were obtained from the World Health Organization Global Information System of Alcohol and Health. We constructed generalized linear models to assess the association between the number of PHP (in 2010) and health outcomes (in 2016). In Latin America, the prevalence of obesity was 27% and 26.1% among male and female populations, respectively. The estimated alcohol per capita consumption among the population at 15 years old or older was 6.8 L of pure alcohol (5.6 recorded and 1.2 unrecorded). The overall prevalence of alcohol use disorders (AUD) was 4.9%. ALD was the main cause of cirrhosis in 64.7% of male and 40.0% of female populations. A total of 19 (95%) countries have at least one alcohol-related PHP on alcohol. The most frequent PHP were limiting drinking age (95%), tax regulations (90%), drunk-driving policies and countermeasures (90%), and government monitoring systems and community support (90%). A higher number of PHP was associated with a lower ALD mortality (PR, 0.76; 95% CI, 0.61-0.93; P = 0.009), lower AUD prevalence (PR, 0.80; 95% CI, 0.65-0.99; P = 0.045), and lower alcohol-attributable road traffic deaths (PR, 0.81; 95% CI, 0.65-1.00; P = 0.051)., Conclusions: Our study indicates that in Latin America, countries with higher number of PHP have lower mortality due to ALD, lower prevalence of AUD, and lower alcohol-attributable road traffic mortality., (© 2021 by the American Association for the Study of Liver Diseases.)

Background: Alcohol use and alcohol-associated liver disease (ALD) burden are increasing in young individuals., Aim: To assess host factors associated with this burden., Methods: National Health and Nutrition Examination Survey (NHANES), National Inpatient Sample (NIS), and United Network for Organ Sharing (UNOS) databases (2006-2016) were used to identify individuals with harmful alcohol use, ALD-related admissions, and ALD-related LT listings respectively., Results: Of 15 981 subjects in NHANES database, weighted prevalence of harmful alcohol use was 17.7%, 29.3% in <35 years (G1) versus 16.9% in 35-64 years (G2) versus 5.1% in ≥65 years (G3). Alcohol use was about 11 and 4.7 folds higher in G1 and G2 versus G3, respectively. Male gender and Hispanic race associated with harmful alcohol use. Of 593 600 ALD admissions (5%, 77%, and 18% in G1-G3 respectively), acute on chronic liver failure (ACLF) occurred in 7.2%, (7.2 in G2 vs 6.7% in G1 and G3, P < 0.001). After controlling for other variables, ACLF development among ALD hospitalizations was higher by 14% and 10% in G1 and G2 versus G3, respectively. Female gender and Hispanic race were associated with increased ACLF risk by 8% and 17% respectively. Of 20,245 ALD LT listings (3.4%, 84.4%, and 12.2% in G1-G3 respectively), ACLF occurred in 28% candidates. Risk of severe (grade 2 or 3) ACLF was higher by about 1.7 fold in G1, 1.5 fold in females and 20% in Hispanics., Conclusion: Young age, female gender, and Hispanic race are independently associated with ALD-related burden and ACLF in the United States. If these findings are validated in prospective studies, strategies will be needed to reduce alcohol use in high risk individuals to reduce burden from ALD., (© 2021 John Wiley & Sons Ltd.)

- Abstract
Alcohol-associated hepatitis (AH) is a unique clinical syndrome in patients with excessive and prolonged alcohol consumption, and negatively impacts the patient outcomes. Among patients with asymptomatic alcohol-associated liver disease with elevated liver enzymes and/or steatosis, liver biopsy is required to diagnose AH. Noninvasive assessment should be performed in these patients to determine risk of advanced fibrosis. In symptomatic patients with jaundice, liver biopsy is required when the clinical diagnosis is uncertain. Liver biopsy is not recommended to determine prognosis of patients with AH. Noninvasive biomarkers are emerging for diagnosis of and determining prognosis of patients with AH., (Copyright © 2021 Elsevier Inc. All rights reserved.)

- Abstract
Importance: Alcohol-associated liver disease results in cirrhosis in approximately 10% to 20% of patients. In 2017, more than 2 million people had alcohol-associated cirrhosis in the US. Alcohol-associated liver disease is the primary cause of liver-related mortality and the leading indication for liver transplant, representing 40% to 50% of all liver transplant in high-income countries., Observations: Steatosis, alcoholic hepatitis, and fibrosis are the 3 pathologic findings that are associated with progression to cirrhosis, with highest risk in patients with alcoholic hepatitis. The amount and duration of alcohol consumption, female sex, obesity, and specific genetic polymorphisms such as patatin-like phospholipase domain protein 3, membrane bound O-acyltransferase, and transmembrane 6 superfamily member 2 genes are risk factors for alcohol-associated liver disease progression. Ten-year survival of patients with alcohol-associated liver disease is 88% among those who are abstinent and 73% for those who relapse to alcohol consumption. Symptomatic alcoholic hepatitis is characterized by rapid onset of jaundice and a 30% risk of mortality 1 year after diagnosis. Severe alcoholic hepatitis, defined as a modified discriminant function score greater than or equal to 32 or Model for End-Stage Liver Disease score (starts at 6 and capped at 40; worst = 40) greater than 20, is associated with the development of acute-on-chronic liver failure and multiorgan failure. Corticosteroid therapy is associated with improved 1-month survival from 65% in untreated patients to 80% in treated patients. Early liver transplant may be appropriate in highly select patients with severe alcoholic hepatitis who do not respond to medical therapy. In patients with decompensated cirrhosis, liver transplant should be considered if the Model for End-Stage Liver Disease score remains greater than 17 after 3 months of alcohol abstinence. Between 2014 and 2019, the proportion of patients waiting for liver transplantation who had alcohol-associated liver disease increased from 22% to 40%. Alcohol-associated cirrhosis accounted for approximately 27% of 1.32 million deaths worldwide related to cirrhosis in 2017., Conclusions and Relevance: Alcohol-associated liver disease is among the most common liver diseases and more than 2 million people in the US in 2017 had alcohol-associated cirrhosis. Corticosteroid therapy improves survival in select patients with severe alcoholic hepatitis. Liver transplantation is the most effective therapy in patients with decompensated liver disease.

- Abstract
Objectives: Alcoholic liver disease (ALD) prevalence, particularly the subset with advanced liver disease, is not well defined. Herein, we aim to provide a comprehensive assessment of ALD epidemiology across the spectrum of disease severity and across different settings using 3 unique US databases., Methods: We performed a retrospective, observational study of US adults with ALD using 2001-2016 National Health and Nutrition Examination Survey (NHANES), 2007-2014 Nationwide Inpatient Sample (NIS), and 2007-2017 United Network for Organ Sharing (UNOS) registry. ALD in the NHANES was defined using clinical laboratory data and self-reported alcohol use, among which fibrosis-4 score of >2.67 defined stage ≥3 fibrosis. Alcoholic cirrhosis (AC) in the NIS was identified using International Classification of Diseases, Ninth Revision codes. ALD in the UNOS was identified using UNOS coding., Results: From 2001-2002 to 2015-2016, the overall weighted ALD prevalence was stable from 8.8% to 8.1% (P = 0.102), whereas the proportion of ALD with stage ≥3 fibrosis increased from 2.2% (95% CI: 0.4-4.0) to 6.6% (95% CI: 2.0-9.9; P = 0.007) (NHANES). From 2007 to 2014, the number of hospitalizations among patients with AC per 1,000 increased by 32.8%, and the proportion of hospitalizations among the patients with AC with ≥3 cirrhosis complications increased from 11.6% in 2007 to 25.8% in 2014 (Ptrend < 0.0001) (NIS). From 2007 to 2017, the total number of adults with ALD listed for liver transplant increased by 63.4% and the proportion with concurrent hepatocellular carcinoma increased by 178% (UNOS)., Discussion: Among these 3 US databases, consistent observations of increasing ALD severity emphasize the urgent need for greater awareness about the consequences of unhealthy alcohol use and interventions aimed specifically at addressing alcohol use disorders.

- Abstract
Alcohol abuse is a major determinant of public health outcomes. Worldwide data from 2016 indicate that alcohol is the seventh leading risk factor in terms of disability-adjusted life years, an increase of more than 25% from 1990 to 2016. Understanding the epidemiology of alcoholic liver disease, including the regional variations in consumption and public policy, is an area of active research. In countries where the per capita consumption of alcohol decreases, there appears to be an associated decrease in disease burden. Given alcohol's health burden, an increased focus on alcohol control policies is needed., (Copyright © 2018 Elsevier Inc. All rights reserved.)

- Abstract
Alcohol-associated liver disease (AALD) is the third most common preventable cause for disease burden and mortality in the US. AALD, including alcoholic hepatitis (AH), contributes to half of admissions from decompensated liver disease and 20% of all liver transplants in the US. Peripheral blood cells contribute to systemic inflammation, oxidative stress, mitochondrial dysfunction, and fibrosis in AALD and AH. Alcohol dysregulates function of lymphocytes, neutrophils, monocytes, and tissue macrophages of the innate immune system. These alterations in turn can modulate adaptive immune responses. In this review, we describe these disruptive effects of alcohol on cells of the innate and adaptive immune system and focus on cellular-based emerging biomarkers on diagnosis and prognosis of patients with AALD and AH.

- Abstract
Alcoholic liver disease (ALD) comprises a clinical-histologic spectrum including fatty liver, alcoholic hepatitis (AH), and cirrhosis with its complications. Most patients are diagnosed at advanced stages and data on the prevalence and profile of patients with early disease are limited. Diagnosis of ALD requires documentation of chronic heavy alcohol use and exclusion of other causes of liver disease. Prolonged abstinence is the most effective strategy to prevent disease progression. AH presents with rapid onset or worsening of jaundice, and in severe cases may transition to acute on chronic liver failure when the risk for mortality, depending on the number of extra-hepatic organ failures, may be as high as 20-50% at 1 month. Corticosteroids provide short-term survival benefit in about half of treated patients with severe AH and long-term mortality is related to severity of underlying liver disease and is dependent on abstinence from alcohol. General measures in patients hospitalized with ALD include inpatient management of liver disease complications, management of alcohol withdrawal syndrome, surveillance for infections and early effective antibiotic therapy, nutritional supplementation, and treatment of the underlying alcohol-use disorder. Liver transplantation, a definitive treatment option in patients with advanced alcoholic cirrhosis, may also be considered in selected patients with AH cases, who do not respond to medical therapy. There is a clinical unmet need to develop more effective and safer therapies for patients with ALD.

- Abstract
Alcoholic cirrhosis remains the second most common indication for liver transplantation. A comprehensive medical and psychosocial evaluation is needed when making a decision to place such patients on the transplant list. Most transplant centers worldwide need a minimum of 6 mo of alcohol abstinence for listing these patients. Patients with alcohol dependence are at high risk for relapse to alcohol use after transplantation (recidivism). These patients need to be identified and require alcohol rehabilitation treatment before transplantation. Recidivism to the level of harmful drinking is reported in about 15%-20% cases. Although, recurrent cirrhosis and graft loss from recidivism is rare, occurring in less than 5% of all alcoholic cirrhosis-related transplants, harmful drinking in the post-transplant period does impact the long-term outcome. The development of metabolic syndrome with cardiovascular events and de novo malignancy are important contributors to non liver-related mortality amongst transplants for alcoholic liver disease. Surveillance protocols for earlier detection of de novo malignancy are needed to improve the long-term outcome. The need for a minimum of 6 mo of abstinence before listing makes transplant a nonviable option for patients with severe alcoholic hepatitis who do not respond to corticosteroids. Emerging data from retrospective and prospective studies has challenged the 6 mo rule, and beneficial effects of liver transplantation have been reported in select patients with a first episode of severe alcoholic hepatitis who are unresponsive to steroids.

- Abstract
The liver plays an important role in the metabolism, synthesis, storage, and absorption of nutrients. Patients with cirrhosis are prone to nutritional deficiencies and malnutrition, with a higher prevalence among patients with decompensated disease. Mechanisms of nutritional deficiencies in patients with liver disease are not completely understood and probably multifactorial. Malnutrition among patients with cirrhosis or alcoholic liver disease correlates with poor quality of life, increased risk of infections, frequent hospitalizations, complications, mortality, poor graft and patient survival after liver transplantation, and economic burden. Physicians, including gastroenterologists and hepatologists, should be conversant with assessment and management of malnutrition and nutritional supplementation., (Copyright © 2012 Elsevier Inc.

- Abstract
Oxidative stress is commonly associated with a number of liver diseases and is thought to play a role in the pathogenesis of chronic hepatitis C, alcoholic liver disease, non-alcoholic steatohepatitis (NASH), haemochromatosis and Wilson's disease. Antioxidant therapy has thus been considered to have the possibility of beneficial effects in the management of these liver diseases. Despite this promise, antioxidants have produced mixed results in a number of clinical trials of efficacy. This review summarizes the results of clinical trials of antioxidants as sole or adjuvant therapy of chronic hepatitis C, alcoholic liver disease and non-alcoholic steatohepatitis (NASH). Overall, the most promising results to date are for vitamin E therapy of NASH but some encouraging results have been obtained with antioxidant therapy of acute alcoholic hepatitis as well. Despite evidence for small reductions of serum alanine aminotransferase, there is as yet no convincing evidence that antioxidant therapy itself is beneficial to patients with chronic hepatitis C. Problems such as small sample size, short follow up duration, inadequate endpoints, failure to demonstrate tissue delivery and antioxidant efficacy, and heterogeneous nature of the 'antioxidant' compounds used have complicated interpretation of results of the clinical studies. These limitations and their implications for future trial design are discussed., (© 2011 John Wiley & Sons A/S.)
