Hospital admissions for chronic liver diseases: a temporal study in the South Region of Brazil.

OBJECTIVE: The aim of the study was to compare the epidemiology and clinical profiles of hospital admissions in a single Brazilian Hepatology Unit from the period 2014-2017 to 2019-2022. METHODS: A retrospective analysis of hospital database from the abovementioned periods was done. The study included patients over the age of 18 years who were hospitalized due to complications of diseases such as viral hepatitis, alcoholic disease, nonalcoholic fatty liver disease, and autoimmune liver and drug-induced hepatitis. RESULTS: In both study periods, middle-aged males were predominant and were younger than females. In the first period (2014-2017), hepatitis C (33.5%) was the most prevalent cause of admission, followed by alcoholic liver disease (31.7%). In the second period (2019-2022), nonalcoholic fatty liver disease (38%) and alcoholic liver disease (27.6%) were the most frequent causes of admission. No changes were observed in the proportion of alcoholic liver disease or drug-induced hepatitis in both study periods. The prevalence of viral hepatitis decreased in both genders, with hepatitis C decreasing from 32.4 to 9.7% for males and 35.4 to 10.8% for females, and OR=0.2; 95%CI 0.1-0.3 for both males and females. Similarly, the prevalence of hepatitis B decreased from 19.1 to 8.1% and OR=0.3; 95%CI 0.2-0.5 for males and 8.2 to 3.7% and OR=0.4; 95%CI 0.1-0.9 for females. The prevalence of autoimmune liver diseases increased only in males, from 2.1 to 5.9% and OR=2.9; 95%CI 1.2-6.6. CONCLUSION: Over the past 4 years, there has been a shift in hospital admission profile at a Brazilian Hepatology Unit, with a decrease in viral hepatitis and an increase in autoimmune diseases and nonalcoholic fatty liver disease. Males were more affected at younger ages than females. Furthermore, ascites was the most prevalent cause of complications in both periods analyzed.

Is There a Safe Alcohol Consumption Limit for the General Population and in Patients with Liver Disease?

Excessive alcohol consumption represents an important burden for health systems worldwide and is a major cause of liver- and cancer-related deaths. Alcohol consumption is mostly assessed by self-report that often underestimates the amount of drinking. While alcohol use disorders identification test - version C is the most widely used test for alcohol use screening, in patients with liver disease the use of alcohol biomarker could help an objective assessment. The amount of alcohol that leads to significant liver disease depends on gender, genetic background, and coexistence of comorbidities (i.e., metabolic syndrome factors). All patients with alcohol-associated liver disease are recommended to follow complete abstinence and they should be treated within multidisciplinary teams. Abstinence slows down and even reverses the progression of liver fibrosis and can help recompensate patients with complicated cirrhosis. Whether there is a safe amount of alcohol in the general population is a matter of intense debate. Large epidemiological studies showed that the safe amount of alcohol to avoid overall health-related risks is lower than expected even in the general population. Even one drink per day can increase cancer-related death. In patients with any kind of chronic liver disease, especially in those with metabolic-associated steatotic liver disease, no alcohol intake is recommended. This review article discusses the current evidence supporting the deleterious effects of small-to-moderate amounts of alcohol in the general population and in patients with underlying chronic liver disease.

Proactive case finding of alcohol-related liver disease in high-risk populations: A systematic review.

BACKGROUND: Alcohol-related liver disease (ARLD) is often diagnosed at a late stage when mortality is unacceptably high. Earlier identification of ARLD may lead to reduced alcohol intake, participation in hepatocellular carcinoma surveillance and reduction in liver-related morbidity and mortality. People with alcohol use disorder (AUD) are at highest risk of ARLD. The aim of this systematic review was to understand the yield of proactive screening for ARLD amongst high-risk groups. METHODS: Embase, Medline, Scopus and grey literature were searched for studies describing proactive assessment for alcohol-related liver disease in people with a history of alcohol excess or diagnosed AUD. Outcomes of interest were fibrosis and cirrhosis detection rates, clinical outcomes, portal hypertension evaluation, attendance at follow-up and cost-effectiveness. RESULTS: Fifteen studies were identified for inclusion from 1115 returned by the search. Four key settings for patient engagement were identified as inpatient addiction services, outpatient addiction services, general acute hospital admissions and community outreach. Of these, acute hospital admissions were the highest yield for cirrhosis at 10.8%-29.6% and community outreach the lowest was 1.2%-2.3%. CONCLUSIONS: Targeted fibrosis assessment of high-risk populations for ARLD is feasible to conduct and identifies a proportion of patients at risk of advanced liver disease. The highest yield is amongst inpatients admitted with AUD. Prospective work is needed to establish which are the most effective and acceptable screening methods and the impact on long-term outcomes.

Racial and ethnic disparities in alcohol-associated liver disease in the United States: A systematic review and meta-analysis.

BACKGROUND: Alcohol-associated liver disease (ALD), encompassing alcohol-associated hepatitis and alcohol-associated cirrhosis, is rising in the United States. Racial and ethnic disparities are evident within ALD; however, the precise nature of these disparities is poorly defined. METHODS: We conducted a search of the PubMed/MEDLINE and EMBASE databases to identify studies published from inception through September 2023 that reported ALD incidence, prevalence, and mortality within the United States, stratified by race and ethnicity. We calculated pooled prevalence and incidence by race and ethnicity, including risk ratios and ORs for ALD pooled prevalence and alcohol-associated hepatitis/alcohol-associated cirrhosis pooled proportions, and OR for ALD mortality using the DerSimonian and Laird method for random-effect models. RESULTS: We identified 25 relevant studies (16 for quantitative meta-analysis), comprising 76,867,544 patients. ALD prevalence was highest in Hispanic (4.5%), followed by White (3.1%) and Black (1.4%) individuals. Pooled risk ratios of ALD prevalence were 1.64 (95% CI: 1.12-2.39) for Hispanic and 0.59 (95% CI: 0.35-0.87) for Black compared to White individuals. Mortality among those with ALD did not significantly differ between White and Hispanic (OR: 1.54, 95% CI: 0.9-2.5; I2=0%), Black (OR: 1.2, 95% CI: 0.8-1.6; I2=0%), or Native American (OR: 2.41, 95% CI: 0.9-2.9) individuals, while there was a significant difference between White and Asian (OR: 0.1; 95% CI: 0.03-0.5) individuals. Most data were cross-sectional and assessed to be of poor or fair quality. CONCLUSIONS: Differences were observed in ALD epidemiology, including higher prevalence among Hispanic and lower prevalence among Black individuals, although there were smaller differences in ALD mortality. Differences in ALD prevalence and prognosis remain poorly defined based on existing data, highlighting a need for higher-quality epidemiological studies in this area.

[Epidemiological characteristics of inpatients with liver failure at the Beijing You'an Hospital from 2012 to 2021].

Objective: To elucidate the epidemiological characteristics and changing trends of liver failure in order to provide evidence-based strategies for prevention and treatment. Methods: The epidemiological information of inpatients with liver failure admitted and treated at Beijing You'an Hospital from 2012 to 2021 was retrospectively collected. The trend test was used to analyze age, gender, as well as the year-by-year changes in the underlying acute and chronic etiology of acute liver failure (ALF), sub-acute liver failure (SALF), acute-on-chronic liver failure (ACLF), and chronic liver failure (CLF). Results: During the study period, information on a total of 8512 inpatients, aged 51.3±13.5 years and mainly male (71.9%) with liver failure, was collected. The highest to lowest proportions of liver failure types were ACLF 4 023 (47.3%), CLF 3 571(42.0%), SALF 670 (7.9%), and ALF 248 (2.9%). The top five causes of liver failure in the overall population, accounting for 87.6% of the total, were hepatitis B 3 199 (37.58%), alcoholic liver disease 2 237 (26.28%), cryptogenic liver disease 906(10.61%), hepatitis B + alcoholic liver disease 603 (7.08%), drugs 488 (5.73%), The top three etiologies of patients with different types of liver failure were acute etiologies for acute liver failure (ALF), followed by drugs 107 (43.1%), hepatitis B 47(19.0%), and unknown etiology 36 (14.5%); sub-acute liver failure (SALF), followed by drugs 381(56.9%), unknown etiology 106 (15.8%), and sepsis 56 (8.4%); and acute-on-chronic liver failure (ACLF), followed by drugs 2 092(52.0%), alcoholic liver disease 813(20.2%), and cryptogenic liver disease 398(9.9%); and chronic etiologies for chronic liver failure (CLF), followed by alcoholic liver disease 1 410(39.5%), hepatitis B 1 028(28.8%), and cryptogenic liver disease 364(10.2%). Longitudinal analysis showed that the average age of patients with liver failure increased year by year, but the sex ratio trend did not change significantly, with male patients predominating throughout. The proportion of drug-induced liver failure in patients with ALF and SALF increased year by year, and the difference in the trend test was statistically significant (P < 0.05). The proportion of patients with chronic etiologies of ACLF and CLF decreased year by year among hepatitis B, while the proportion of alcoholic liver disease, autoimmune liver disease, and cryptogenic liver disease increased year by year (the difference was statistically significant, P < 0.05). Conclusion: The etiological spectrum of liver failure is changing in our country. Although hepatitis B is still the main cause of liver failure, its proportion shows a decreasing trend year by year, with the exception of ACLF, which is no longer the primary etiology of other types of liver failure, while drug-induced liver disease, alcoholic liver disease, autoimmune liver disease, and cryptogenic liver disease are increasing year by year and will become the focus of liver disease prevention and treatment in the future.

Misclassified Alcohol-related Liver Disease is Common in Presumed Metabolic Dysfunction-associated Steatotic Liver Disease and Highly Increases Risk for Future Cirrhosis.

BACKGROUND & AIMS: Alcohol overconsumption is a risk factor for disease progression in patients with presumed metabolic dysfunction-associated steatotic liver disease (MASLD). How commonly this occurs and how it affects progression to major adverse liver outcomes (MALOs) is not well known. METHODS: We did a register-based cohort study, including all patients with a diagnosis of MASLD in Sweden between 1987 and 2020. Patients were stratified on co-occurrence of diagnoses of alcohol-related liver disease (ALD) or alcohol use disorder (AUD) prior to MASLD diagnosis. Incident MALOs were derived from national registers. Cox regression was used to calculate hazard ratios (HRs) for incident MALO. RESULTS: A total of 15,107 patients with MASLD were identified. The median age was 55 years, and 52% were female. Of the patients, 1843 (12%) had a prior diagnosis of ALD or AUD. During follow-up, a further 787 patients (5.2%) received a diagnosis of ALD or AUD. Patients with previous ALD or AUD diagnoses at or before baseline had considerably higher rates of MALOs compared with patients without (19.5% vs 7.8%; adjusted HR, 3.12; 95% confidence interval, 2.74-3.55). Acquiring an ALD or AUD diagnosis after MASLD diagnosis was associated with higher rates of MALOs (adjusted HR, 5.81; 95% confidence interval, 4.90-6.88). CONCLUSIONS: ALD or AUD is commonly diagnosed prior to or after MASLD diagnosis. Such patients have considerably higher rates of progression to MALOs. Correctly separating between MASLD and ALD is vital to assess prognosis.

Imaging of Alcohol-Associated Liver Disease.

Alcohol-associated liver disease (ALD) continues to be a global health concern, responsible for a significant number of deaths worldwide. Although most individuals who consume alcohol do not develop ALD, heavy drinkers and binge drinkers are at increased risk. Unfortunately, ALD is often undetected until it reaches advanced stages, frequently associated with portal hypertension and hepatocellular carcinoma (HCC). ALD is now the leading indication for liver transplant. The incidence of alcohol-associated hepatitis (AH) surged during the COVID-19 pandemic. Early diagnosis of ALD is therefore important in patient management and determination of prognosis, as abstinence can halt disease progression. The spectrum of ALD includes steatosis, steatohepatitis, and cirrhosis, with steatosis the most common manifestation. Diagnostic techniques including ultrasound, CT, and MRI provide useful information for identifying ALD and excluding other causes of liver dysfunction. Heterogeneous steatosis and transient perfusion changes on CT and MRI in the clinical setting of alcohol-use disorder are diagnostic of severe AH. Elastography techniques are useful for assessing fibrosis and monitoring treatment response. These various imaging modalities are also useful in HCC surveillance and diagnosis. This review discusses the imaging modalities currently used in the evaluation of ALD, highlighting their strengths, limitations, and clinical applications.

The Rising Costs of Alcohol-Associated Liver Disease in the United States.

INTRODUCTION: Alcohol-associated liver disease (ALD) is rising in the United States because of an increase in high-risk drinking, but population-level ALD cost is unknown. Our aim was to project the direct and indirect costs associated with ALD in the US population through 2040. METHODS: We used a previously validated microsimulation model of alcohol consumption and ALD with model parameters estimated from publicly available data sources, including the National Epidemiologic Survey Alcohol and Related Conditions-III, the Center for Disease Control and Prevention Wide-ranging Online Data for Epidemiologic Research, the Bureau of Labor Statistics, and published studies informing the impact of alcohol consumption on ALD severity in the United States resident population. The simulated scenario included current and projected ALD-associated costs. RESULTS: From 2022 to 2040, the ALD is projected to cost $880 billion, $355 billion in direct healthcare-related costs, and $525 billion in lost labor and economic consumption. The annual cost of ALD is projected to increase from $31 billion in 2022 to $66 billion (118% increase) in 2040. Although the female population makes up 29% of these costs in 2022, by 2040 on a per annum basis, female costs would be 43% of the total annual expenditure. DISCUSSION: Increased consumption of alcohol in the US population, especially in females, will cause a steep rise in the economic burden of ALD in the United States. These findings highlight the need for planners and policymakers to plan for the increased impact of liver disease in the United States.

Alcohol-associated liver disease: Epidemiology and management.

Alcohol is the leading cause of preventable liver morbidity and mortality worldwide, as it is also the most frequent cause of advanced liver disease. Alcohol-associated liver disease (ALD) covers different phenotypes ranging from steatosis to the development of inflammation (steatohepatitis), fibrosis and ultimately, in a proportion of patients, the development of liver cirrhosis and its associated complications. ALD has a complex pathogenesis that includes the interplay of both genetic and environmental factors, yet the precise mechanisms are largely unknown. Alcohol-associated hepatitis (AH) is a severe clinical presentation of ALD, which is characterized by abrupt jaundice and clinical decompensations of liver disease. AH occurs in a percentage of patients with underlying ALD and active alcohol consumption. Currently, there are no approved targeted therapies able to interfere in the pathogenesis of ALD and halt the progression of the disease, therefore alcohol abstinence is the most effective measure to improve prognosis in this patient population. In this regard, alcohol cessation remains the first-line treatment in all stages of alcohol disease. In patients with advanced ALD nonresponding to medical therapy, liver transplantation is the only approach that improves prognosis, and it should be considered in patients with decompensated cirrhosis. In the last years, AH has emerged as a new indication of early liver transplantation in non-responders to medical therapy, with promising results in highly selected patients. In this review, we provide an update on the epidemiology, risk factors, natural history, diagnosis, pathogenesis, and current treatments for ALD, taking into account the importance of assessing and managing alcohol consumption as the etiological factor and the main driver of prognosis in patients with ALD.

Dual alcohol and metabolic-related liver disease: Results from a population of liver transplant patients.

BACKGROUND & AIMS: If alcohol-related liver disease (ALD) and nonalcoholic fatty liver disease (NAFLD) are now the two main indications for liver transplantation (LT), it has been recognized that both conditions can coexist in varying degrees and the concept of dual-aetiology fatty liver disease (DAFLD) has been proposed. This retrospective study aimed to evaluate, in a cohort of patients transplanted for ALD and NAFLD, the prevalence of DAFLD before LT and the impact on liver graft outcome. METHODS: From 1990 to 2010, all patients who underwent LT for the so-called ALD or NAFLD in our centre were included. Before LT, DAFLD was defined as patients with a history of excessive alcohol consumption and obesity associated with either diabetes or hypertension. Before LT, patients were separated into three groups: DAFLD, ALD, and NAFLD. Fatty liver graft disease was classified according to the FLIP algorithm. RESULTS: Out of 907, adult LT recipients were identified: 33 DAFLD patients, 333 ALD patients, and 24 NAFLD patients. After LT, ALD patients experienced significantly more alcohol relapse than DAFLD patients, who had twice more post-LT metabolic syndrome. Out of 926, post-LT biopsies, DAFLD patients had significantly more fatty liver graft disease due to metabolic syndrome features than ALD patients. CONCLUSION: Our results support that DAFLD recently emerged as an indication of LT. In the future, this particular population needs to be identified as a specific entity since post-LT outcome on the graft is different from ALD and more similar to NAFLD patients.

Between-hospital care referrals for severe alcohol-related liver disease during the COVID-19 pandemic, 2020 to 2022.

Increased alcohol consumption during the coronavirus disease 2019 pandemic is projected to impact alcohol-related liver disease (ALD) morbidity and mortality. Inter-hospital escalation-of-care referral requests to our tertiary-care hepatology unit were analyzed from January 2020 through December 2022. Most requests to our center were for ALD with an increase in requests from intermediate care units, suggestive of higher acuity illness.

From Shadows to Spotlight: Exploring the Escalating Burden of Alcohol-Associated Liver Disease and Alcohol Use Disorder in Young Women.

INTRODUCTION: The burden of alcohol-related complications is considerable, particularly alcohol-associated liver disease and alcohol use disorder (AUD). However, there are deficiencies in comprehensive epidemiological research focusing on these issues, especially among young women who display higher susceptibility to such complications compared with their male counterparts. We thus aimed to determine the global burden of these conditions in this vulnerable group. METHODS: Leveraging data from the Global Burden of Disease Study 2019, we analyzed the prevalence, mortality, and disability-adjusted life years of alcohol-associated cirrhosis (AC), liver cancer from alcohol, and AUD in young women. The findings were categorized by region, nation, and sociodemographic index. RESULTS: The highest age-standardized prevalence rates were observed in AUD (895.96 [95% uncertainty interval (UI) 722.6-1,103.58]), followed by AC (65.33 [95% UI 48.37-86.49]) and liver cancer from alcohol (0.13 [95% UI 0.09-0.19]) per 100,000 people. The highest age-standardized mortality rates were observed in AC (0.75 [95% UI 0.55-0.97]), followed by AUD (0.48 [95% UI 0.43-0.53]) and liver cancer from alcohol (0.06 [95% UI 0.04-0.09]). The highest burdens of AC and AUD were observed in Central Europe, whereas the high-income Asia Pacific had the highest burden of liver cancer from alcohol. DISCUSSION: Throughout the past decade, the trend of AUD varied among regions while the impact of alcohol-associated liver disease has increased, requiring urgent public health strategy to mitigate these complications, particularly in female patients in Europe and the Asia-Pacific region.

The changing epidemiology of adult liver transplantation in the United States in 2013-2022: The dominance of metabolic dysfunction-associated steatotic liver disease and alcohol-associated liver disease.

BACKGROUND: The high prevalence of obesity in the United States drives the burden of NASH, recently renamed as metabolic dysfunction-associated steatohepatitis (MASH). We assessed the most recent trends in liver transplantation in the United States. METHODS: The Scientific Registry of Transplant Recipients (SRTR 2013-2022) was used to select adult (18 years or above) candidates who underwent liver transplant. RESULTS: There were 116,292 candidates who underwent liver transplant with known etiology of chronic liver disease. In candidates without HCC, the most common etiology was alcohol-associated liver disease (ALD), increasing from 23% (2013) to 48% (2022), followed by NASH/MASH, which increased from 19% to 27%; the rates of viral hepatitis decreased (chronic hepatitis C: 28%-4%; chronic hepatitis B: 1.8%-1.1%) (all trend p<0.01). The proportion of HCC decreased from 25% (2013-2016) to 17% (2021-2022). Among HCC cohort, the proportion of chronic hepatitis C decreased from 60% (2013) to 27% (2022), NASH/MASH increased from 10% to 31%, alcohol-associated liver disease increased from 9% to 24% (trend p<0.0001), and chronic hepatitis B remained stable between 5% and 7% (trend p=0.62). The rapid increase in the proportion of NASH/MASH in HCC continued during the most recent study years [20% (2018), 28% (2020), 31% (2022)]; the trend remained significant after adjustment for age, sex, ethnicity, obesity, and type 2 diabetes. CONCLUSIONS: Liver transplant etiologies in the United States have changed over the last decade. Alcohol-associated liver disease and NASH/MASH remain the 2 most common indications for transplantation among those without HCC, and NASH/MASH is the most common in patients with HCC.

Advances in the understanding and management of alcohol-related liver disease.

Alcohol-related liver disease (ALD) is a major cause of liver-related morbidity and mortality. Epidemiological trends indicate recent and predicted increases in the burden of disease. Disease progression is driven by continued alcohol exposure on a background of genetic predisposition together with environmental cofactors. Most individuals present with advanced disease despite a long history of excessive alcohol consumption and multiple missed opportunities to intervene. Increasing evidence supports the use of non-invasive tests to screen for and identify disease at earlier stages. There is a definite role for public health measures to reduce the overall burden of disease. At an individual level, however, the ability to influence subsequent disease course by modifying alcohol consumption or the underlying pathogenic mechanisms remains limited due to a comparative lack of effective, disease-modifying medical interventions. Abstinence from alcohol is the key determinant of outcome in established ALD and the cornerstone of clinical management. In those with decompensated ALD, liver transplant has a clear role. There is consensus that abstinence from alcohol for an arbitrary period should not be the sole determinant in a decision to transplant. An increasing understanding of the mechanisms by which alcohol causes liver disease in susceptible individuals offers the prospect of new therapeutic targets for disease-modifying drugs. Successful translation will require significant public and private investment in a disease area which has traditionally been underfunded when compared to its overall prevalence.

Multidisciplinary Care of Alcohol-related Liver Disease and Alcohol Use Disorder: A Narrative Review for Hepatology and Addiction Clinicians.

PURPOSE: Models of integrated, multidisciplinary care are optimal in the setting of complex, chronic diseases and in the overlap of medical and mental health disease, both of which apply to alcohol-related liver disease (ALD). Alcohol use disorder (AUD) drives nearly all cases of ALD, and coexisting mental health disease is common. ALD is a complex condition with severe clinical manifestations and high mortality that can occasionally lead to liver transplantation. As a result, integrated care for ALD is an attractive proposition. The aim of this narrative review was to: (1) review the overlapping and concerning trends in the epidemiology of AUD and ALD; (2) use a theoretical framework for integrated care known as the "five-component model" as a basis to highlight the need for integrated care and the overlapping clinical manifestations and management of the 2 conditions; and (3) review the existing applications of integrated care in this area. METHODS: We performed a narrative review of epidemiology, clinical manifestations, and management strategies in AUD and ALD, with a particular focus on areas of overlap that are pertinent to clinicians who manage each disease. Previously published models were reviewed for integrating care in AUD and ALD, both in the general ALD population and in the setting of liver transplantation. FINDINGS: The incidences of AUD and ALD are rising, with a pronounced acceleration driven by the Coronavirus Disease 2019 pandemic. Hepatologists are underprepared to diagnose and treat AUD despite its high prevalence in patients with liver disease. A patient who presents with overlapping clinical manifestations of both AUD and ALD may not fit neatly into typical treatment paradigms for each individual disease but rather will require new management strategies that are appropriately adapted. As a result, the dimensions of integrated care, including collective ownership of shared goals, interdependence among providers, flexibility of roles, and newly created professional activities, are highly pertinent to the holistic management of both diseases. IMPLICATIONS: Integrated care models have proliferated as recognition grows of the dual pathology of AUD and ALD. Ongoing coordination across disciplines and research in the fields of hepatology and addiction medicine are needed to further elucidate optimal mechanisms for collaboration and improved quality of care.

Intersection of Coronavirus Disease 2019 and Alcohol-associated Liver Disease: A Review of Emerging Trends and Implications.

PURPOSE: This review will provide an overview of alcohol use and alcohol associated liver disease (ALD) prior to the coronavirus disease 2019 (COVID-19) pandemic and the impact of the pandemic on alcohol use and ALD. Furthermore, this review will explore strategies to mitigate the growing disease burden of AUD and ALD. METHODS: A search using PubMed was performed for articles on topics related to alcohol use, ALD, and COVID-19. The literature was reviewed and pertinent sources were used for this narrative review. FINDINGS: In the United States (US), excessive alcohol use is the third leading cause of preventable death. Prior to the COVID-19 pandemic, the increasing prevalence of alcohol use disorder (AUD) and ALD in the US had already constituted a public health crisis given the association between alcohol misuse, AUD, and ALD with significant medical, economic, and societal burdens. The COVID-19 pandemic led to increased alcohol consumption and downstream consequences, including increased prevalence of AUD, ALD, ALD-related hospitalization and death, and liver transplantation for ALD. IMPLICATIONS: There is a critical need for additional, multi-pronged interventions to mitigate the mortality and morbidity linked to ALD.

Alcohol-Associated Liver Disease: Evolving Concepts and Treatments.

Alcohol is a prominent cause of liver disease worldwide with higher prevalence in developed nations. The spectrum of alcohol-associated liver disease (ALD) encompasses a diverse range of clinical entities, from asymptomatic isolated steatosis to decompensated cirrhosis, and in some cases, acute or chronic liver failure. Consequently, it is important for healthcare practitioners to maintain awareness and systematically screen for ALD. The optimal evaluation and management of ALD necessitates a collaborative approach, incorporating a multidisciplinary team and accounting for concurrent medical conditions. A repertoire of therapeutic interventions exists to support patients in achieving alcohol cessation and sustaining remission, with complete abstinence being the ultimate objective. This review explores the existing therapeutic options for ALD acknowledging geographical discrepancies in accessibility. Recent innovations, including the inclusion of alcohol consumption biomarkers into clinical protocols and the expansion of liver transplantation eligibility to encompass severe alcohol-associated hepatitis, are explored.

The global burden of alcoholic liver disease: a systematic analysis of the global burden of disease study 2019.

Alcohol use is a major risk factor for the burden of mortality and morbidity. Alcoholic cirrhosis (AC) and alcoholic liver cancer (ALC) are most important and severe liver disease outcomes caused by alcohol use. The objectives of the current study were to investigate the global prevalence and burden of disease in disability-adjusted life years (DALYs) for AC and ALC, based on data from the Global Burden of Disease (GBD). Incidence, prevalence, death, and DALYs for GBDs in different locations, years, sex, and age groups were estimated using DisMod-MR 2.1 and a generic Cause of Death Ensemble Modeling approach. The correlations between the age-standardized incidence rate or age-standardized death rate and gender, sociodemographic index (SDI), and alcohol usage were conducted by Generalized Linear Models. Globally, the changes of age-standardized rates of indicators were not much significant over the 30-year period. However, the changes varied widely across regions. Central Asia and East Europe contributed the highest age-standardized incidence, prevalence, death, and DALYs and increased sharply by past 30 years. Generalized Linear Models (GLMs) showed male gender as a risk factor of AC, with the relative risk of incidence of 1.521 and relative risk of death of 1.503. Globally, there were improvements in overall health with regard to GBDs over the 30 years. However, the prevention of AC and ALC should be promoted in middle and middle-high SDI regions, especially Central Asia and East Europe, whereas more medical resources should be provided to improve treatment levels in low SDI region.

Concept and risk factors of alcohol relapse in liver transplant recipients with alcohol-related aetiologies: A scoping review.

Alcohol relapse in those who received liver transplantation (LT) for alcohol-related liver disease can lead to poor graft function, low medication adherence rates and decreased chances of survival. Numerous studies have evaluated on this topic; however, discrepancies in the meaning and measurement of 'alcohol relapse' lead to heterogeneous results. This scoping review aimed to explore the conceptual and operational definitions of alcohol relapse in LT recipients with alcohol-related aetiologies and to examine newly reported risk factors of alcohol relapse. Following the Arksey and O'Malley scoping review method and PRISMA guidelines, structured searches for articles published from 2012 to 2022 were conducted in PubMed, CINAHL, Embase, Cochrane and PsycINFO. Twenty-eight studies were included in the final review. Alcohol relapse was either defined as 'any alcohol consumption' or 'a certain degree of alcohol drinking' after transplantation. Discrepancies in the incidence rates persisted even within studies that shared the same conceptual definition. Commonly reported risk factors for alcohol relapse were younger age, social isolation and shorter abstinence periods before LT. Self-efficacy and post-transplant complications were newly identified risk factors in recent studies; whereas environmental factors such as external stressors were rarely included. The variance in the definition of alcohol relapse and inconsistent identification methods make it difficult to organize a structured interventional study. A standardized stratification of post-LT alcohol relapse behaviour is needed to prior to implementing interventions that employ a harm minimization approach. Cost-effective interventions promoting self-efficacy could enable the prevention and management of alcohol relapse after LT.
