Integrated Care of Alcohol-Related Liver Disease

Management of alcohol use disorder: a gastroenterology and hepatology-focused perspective

Alcohol use disorder is a prevalent and major but preventable cause of morbidity and mortality worldwide, causing several important health consequences, including chronic liver disease. Despite its substantial effects, most clinicians do not adequately assess alcohol intake in clinical practice, and there are several barriers to providing integrated management to patients with alcohol use disorder. Standardised questionnaires, such as the Alcohol Use Identification Test (AUDIT), can facilitate the identification of individuals at risk of alcohol use disorder, and alcohol biomarkers such as phosphatidylethanol aid in quantifying levels of alcohol consumption. Non-pharmacological interventions-including brief interventions, twelve-step facilitation, motivational enhancement therapy, contingency management, and cognitive behavioural therapy-are effective for patients with alcohol use disorder, regardless of the presence of advanced liver disease. Pharmacological treatments should be considered according to the severity of liver disease and other comorbidities, safety profile, and local availability. The management of patients with alcohol use disorder and associated liver disease should ideally be performed in the setting of integrated multidisciplinary teams.

Substance Use Disorders and Interprofessional Management in the Pre and Post Liver Transplant Settings

Substance use disorders (SUDs) are rising in the general population and also in the transplant population. Alcohol use disorder leading to alcohol-associated liver disease is the most common of all SUDs in the liver transplantation setting. Uncontrolled SUDs and relapse after transplant can lead to graft loss and mortality, as well as reduce quality of life and patient functioning. SUDs can be treated effectively through integrated, interprofessional management by addiction and medical/surgical professional members of the transplant team. Teams should be aware of pitfalls in interprofessional teamwork and communication so that corrective steps could be implemented for improved efficiency.

Liver Transplant Provider Perspectives on Posttransplant Management of Alcohol Use Disorder

Background

Liver transplantation (LT) is the standard treatment for liver failure secondary to alcohol-associated liver disease, but limited literature and best practices exist for post-LT treatment of alcohol use disorder (AUD). This study explores current AUD management practices and providers' perceived barriers to effective post-LT AUD management.

Methods

A 45-item survey on post-LT AUD treatment practices was distributed to members of the American Society of Transplant Surgeons, the Association of Consult/Liaison Psychiatry Transplant Special Interest Group, and both the American Society of Transplantation's Liver and Intestine Community of Practice and Psychosocial and Ethics Community of Practice discussion boards, between December 2021 and April 2022. Univariate analysis of categorical variables was performed using the chi-square test. Data were analyzed using center volume tertiles, country region, and provider professional activity.

Results

Two hundred thirty-two respondents from 70 LT centers across all 11 United Network for Organ Sharing regions completed the survey. Half of the them were attending physicians and 16.4% were nurse coordinators. Most centers (84%) aimed for alcohol abstinence for all post-LT patients. Perceived barriers to AUD treatment efficacy included ongoing desire to drink (18%), denial about alcohol misuse (14.9%), and lack of posttransplant support (14%). Additionally, 62.1% of centers had no policy for prescribing medication-assisted therapy to treat AUD, and 32.7% of centers reported no center-level changes in AUD care. Providers identified primary needs as hiring additional mental health professionals (30.8%), dedicating specific staff to AUD care (24.7%), and standardizing psychiatric/psychological care in transplant clinics (17.2%).

Conclusions

Despite the increasing volume of LT for alcohol-associated liver disease, significant perceived barriers to effective AUD treatment remain.

Contingency management to promote treatment engagement in comorbid alcohol use disorder and alcohol-related liver disease: Findings from a pilot randomized controlled trial

BACKGROUND

Alcohol-related liver disease (ARLD) is a leading cause of preventable death and health inequalities. Evidence-based interventions for comorbid alcohol use disorder (AUD) and ARLD remain limited, and only a small proportion of this clinical population engages with treatment. There is a need to improve patient outcomes by bridging this gap through novel, person-centred interventions. Contingency management (CM) is a psychosocial intervention that involves gradual, increasing incentives upon the completion of treatment-related goals, such as treatment attendance. This single-centre, randomized pilot trial of voucher-based CM was conducted to promote treatment engagement in comorbid AUD and ARLD.

METHODS

Thirty service users were recruited from an inpatient setting, offered integrated liver care (ILC) and allocated to ILC only or ILC + CM. Primary outcomes included feasibility criteria (recruitment, study retention post-randomization, completeness of data and protocol fidelity). Secondary outcome data on engagement, alcohol intake, and liver function were also collected. Data were gathered at baseline, post-ILC, and 12 weeks post-ILC and analyzed through descriptive statistics.

RESULTS

The feasibility of the research was subject to challenges inherent to conducting applied health research in a real-world clinical setting. The recruitment and retention rates were 73.20% and 36.70%, respectively. All participants received CM per protocol. An increasing trend in engagement was observed in the ILC + CM compared to ILC only (67% vs. 33%). A trending 76% reduction in alcohol intake and an overall improvement in liver outcomes were observed among participants engaging with the trial, with no significant differences between control and treatment groups.

CONCLUSION

Overall, the CM intervention was feasible to deliver and appears promising in improving outcomes in individuals with comorbid AUD and ARLD. Aspects related to recruitment, study retention post-randomization, and protocol fidelity need to be further adapted before proceeding with a definitive trial.

Global Burden of Major Chronic Liver Diseases in 2021

BACKGROUND

This study utilised the Global Burden of Disease data (2010-2021) to analyse the rates and trends in point prevalence, annual incidence and years lived with disability (YLDs) for major chronic liver diseases, such as hepatitis B, hepatitis C, metabolic dysfunction-associated liver disease, cirrhosis and other chronic liver diseases.

METHODS

Age-standardised rates per 100,000 population for prevalence, annual incidence and YLDs were compared across regions and countries, as well as the socio-demographic index (SDI). Trends were expressed as percentage changes (PC) and estimates were reported with uncertainty intervals (UI).

RESULTS

Globally, in 2021, the age-standardised rates per 100,000 population for the prevalence of hepatitis B, hepatitis C, MASLD and cirrhosis and other chronic liver diseases were 3583.6 (95%UI 3293.6-3887.7), 1717.8 (1385.5-2075.3), 15018.1 (13756.5-16361.4) and 20302.6 (18845.2-21791.9) respectively. From 2010 to 2021, the PC in age-standardised prevalence rates were-20.4% for hepatitis B, -5.1% for hepatitis C, +11.2% for MASLD and + 2.6% for cirrhosis and other chronic liver diseases. Over the same period, the PC in age-standardized incidence rates were -24.7%, -6.8%, +3.2%, and +3.0%, respectively. Generally, negative associations, but with fluctuations, were found between age-standardised prevalence rates for hepatitis B, hepatitis C, cirrhosis and other chronic liver diseases and the SDI at a global level. However, MASLD prevalence peaked at moderate SDI levels.

CONCLUSIONS

The global burden of chronic liver diseases remains substantial. Hepatitis B and C have decreased in prevalence and incidence in the last decade, while MASLD, cirrhosis and other chronic liver diseases have increased, necessitating targeted public health strategies and resource allocation.

The impact of integrated care on clinical outcomes in patients with alcohol-associated liver disease: Early outcomes from a multidisciplinary clinic

BACKGROUND

We analyzed early outcomes regarding the impact of our integrated alcohol-associated liver disease (ALD) clinic on patients with ALD and alcohol use.

METHODS

We conducted a retrospective study of patients with ALD who were evaluated in our integrated clinic from May 1, 2022, to December 31, 2023. Primary outcomes included differences in baseline clinical/demographic data between patients who accepted versus declined an appointment and changes in the severity of ALD, alcohol consumption, functional status, hospital utilization, and remission in alcohol use disorder for evaluated patients.

RESULTS

Patients who declined appointments (n=66) had higher median no-show rates (15.0 [8.0,30.0] vs. 8.5 [3.25,15.0], p<0.001), social vulnerability index (0.53 [0.26,0.79] vs. 0.38 [0.17,0.63], p=0.033), and proportions of cirrhosis (78.8% vs. 59.8%, p=0.017) versus evaluated patients. Comparison of baseline to first follow-up visit for evaluated patients (n=102) demonstrated significant reductions in median AST (59.5 [41.75, 89] vs. 44.5 [33.5, 56.25], p<0.001), alanine-aminotransferase (33.5 [20,45.25] vs. 26.5 [18.75,33.0], p=0.017), total bilirubin (1.6 [0.7,3.3] vs. 1 [0.5,1.9], p=0.001), phosphatidylethanol (263 [35, 784] vs. 0 [0, 163], p<0.001), MELD-3.0 and Sodium scores for patients with alcohol-associated hepatitis and cirrhosis (16 [11, 18.75] vs. 12 [9, 14], p<0.001), 14 [9.25, 17.75] vs. 11 [8.5, 14], p<0.001), and Child-Turcotte-Pugh scores for patients with cirrhosis (9 [6, 10.5] vs. 7 [6, 9], p<0.001). The proportion of patients with active-severe alcohol use disorder significantly decreased (85.2% vs. 51.9%, p<0.001). Additionally, patients had significant reductions in emergency department utilization (incidence rate ratio of 0.64 emergency department visits/month (p=0.002) and 0.71 hospital admissions/month (p=0.025). However, after considering the false discovery rate, the reduction in hospitalization admissions/month was not statistically significant (False Discovery Rate adjusted p=0.056).

CONCLUSIONS

Our integrated approach led to reductions in liver injury, degree of liver decompensation, alcohol use, and ED utilization, and remission in AUD in a population of both non-transplant ALD and post-transplant patients.

Insights into ALD and AUD diagnosis and prognosis: Exploring AI and multimodal data streams

The rapid evolution of artificial intelligence and the widespread embrace of digital technologies have ushered in a new era of clinical research and practice in hepatology. Although its potential is far from realization, these significant strides have generated new opportunities to address existing gaps in the delivery of care for patients with liver disease. In this review, we discuss how artificial intelligence and opportunities for multimodal data integration can improve the diagnosis, prognosis, and management of alcohol-associated liver disease. An emphasis is made on how these approaches will also benefit the detection and management of alcohol use disorder. Our discussion encompasses challenges and limitations, concluding with a glimpse into the promising future of these advancements.

Liver transplantation for alcohol-associated liver disease

Alcohol-associated liver disease (ALD) is a major cause of morbidity and mortality worldwide, and a leading indication for liver transplantation (LT) in many countries, including the United States. However, LT for ALD is a complex and evolving field with ethical, social, and medical challenges. Thus, it requires a multidisciplinary approach and individualized decision-making. Short-term and long-term patient and graft survival of patients undergoing LT for ALD are comparable to other indications, but there is a continued need to develop better tools to identify patients who may benefit from LT, improve the pretransplant and posttransplant management of ALD, and evaluate the impact of LT for ALD on the organ donation and transplantation systems. In this review, we summarize the current evidence on LT for ALD, from alcohol-associated hepatitis to decompensated alcohol-associated cirrhosis. We discuss the indications, criteria, outcomes, and controversies of LT for these conditions and highlight the knowledge gaps and research priorities in this field.

Integrated and collaborative care across the spectrum of alcohol-associated liver disease and alcohol use disorder

The public health impact of alcohol-associated liver disease (ALD), a serious consequence of problematic alcohol use, and alcohol use disorder (AUD) is growing, with ALD becoming a major cause of alcohol-associated death overall and the leading indication for liver transplantation in the United States. Comprehensive care for ALD often requires treatment of AUD. Although there is a growing body of evidence showing that AUD treatment is associated with reductions in liver-related morbidity and mortality, only a minority of patients with ALD and AUD receive this care. Integrated and collaborative models that streamline both ALD and AUD care for patients with ALD and AUD are promising approaches to bridge this treatment gap and rely on multidisciplinary and interprofessional teams and partnerships. Here, we review the role of AUD care in ALD treatment, the effects of AUD treatment on liver-related outcomes, the impact of comorbid conditions such as other substance use disorders, obesity, and metabolic syndrome, and the current landscape of integrated and collaborative care for ALD and AUD in various treatment settings. We further review knowledge gaps and unmet needs that remain, including the role of precision medicine, the application of harm reduction approaches, the impact of health disparities, and the need for additional AUD treatment options, as well as further efforts to support implementation and dissemination.

The prognostic impact of psychiatric intervention on alcohol-associated liver disease: The UK Biobank cohort study

BACKGROUND/AIMS

Alcohol-associated liver disease (ALD) is a public health concern. ALD patients often have psychiatric comorbidities, but the effects of psychiatric interventions on ALD are not well-established. This study explores the prognostic impact of psychiatric intervention on ALD within UK Biobank cohort.

METHODS

This population-based study included 2,417 ALD patients from the UK Biobank cohort. Psychiatric intervention was defined by a consultation with psychiatrists during hospitalization or a history of medication related to alcohol use disorder and psychiatric comorbidities. Survival analysis was conducted, incorporating propensity score matching (PSM), to precisely assess the impact of psychiatric intervention.

RESULTS

Among 2,417 ALD patients, those with F10 (mental disorders due to alcohol) codes had poorer survival outcomes. Psychiatric intervention significantly improved the outcomes of both all-cause and liver-related mortality and reduced the incidence of liver cirrhosis. In subgroup or 2-year landmark analyses, psychiatric intervention consistently showed a survival benefit in ALD patients. In the multivariate analysis, psychiatric intervention was identified as a favorable prognostic factor (hazard ratio, 0.780; P=0.002 after PSM).

CONCLUSION

This study demonstrates the favorable effect of psychiatric intervention in ALD patients with psychiatric comorbidities. These findings emphasize the importance of integrated management for ALD patients to address both their medical and psychiatric aspects. Therefore, we suggest the potential benefits of early psychiatric interventions in improving survival outcomes in ALD.

Designing clinical trials to address alcohol use and alcohol-associated liver disease: an expert panel Consensus Statement

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.

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.

Reexamining "psychosocial clearance": A procedural framework for psychosocial evaluation in liver transplantation

Psychosocial and "nonmedical" phenomena are commonly encountered in liver transplantation (LT) evaluations. They are simultaneously crucial decision-making factors and some of the most difficult and controversial clinical matters clinicians confront. Epidemiology, societal trends, and the preponderance of psychological and behavioral factors underpinning common end-stage liver diseases ensure that LT teams will continue to encounter highly complex psychosocial patient presentations. Psychosocial policies, practices, and opinions vary widely among clinicians and LT centers. Liver clinicians already report insufficient psychosocial expertise, which creates a large gap between the stark need for psychosocial expansion, improvement, and innovation in LT and the lack of accompanying guidance on how to achieve it. While the clinical domains of an LT psychosocial evaluation have been well-described, few articles analyze the procedures by which teams determine candidates' "psychosocial clearance" and no conceptual frameworks exist. This article proposes a framework of core domains of psychosocial evaluation procedures, common pitfalls, and practical improvement strategies.

Treatment of alcohol use disorder in patients with alcohol-associated liver disease: Innovative approaches and a call to action

Alcohol-associated liver disease is currently the leading cause of liver transplantation and liver deaths both in Europe and the United States. Efficacious treatments exist for alcohol use disorder, but they are seldomly prescribed for patients who need them. Besides, the presence of liver cirrhosis can complicate pharmacological treatment choices. In this review, we discuss established and innovative treatment strategies to treat unhealthy alcohol use in patients with alcohol-associated liver disease. We also describe the experience of our own institutions, Hospital Universitari Germans Trias i Pujol in Badalona (Spain) and Yale-New Haven Health and Yale Medicine (Connecticut. United States of America).

Problematic alcohol use and its impact on liver disease quality of life in a multicenter study of patients with cirrhosis

BACKGROUND

Management of cirrhosis is challenging and has been complicated by the COVID-19 pandemic due to decreased access to care, increased psychological distress, and alcohol misuse. Recently, The National Institute on Alcohol Abuse and Alcoholism has broadened the definition of recovery from alcohol use disorder to include quality of life (QoL) as an indicator of recovery. This study examined the associations of alcohol-associated cirrhosis etiology and problematic drinking with liver disease QoL (LDQoL).

METHODS

Patients with cirrhosis (N=329) were recruited from 3 sites (63% from 2 Veterans Affairs Health Care Systems and 37% from 1 safety net hospital) serving populations that are economically or socially marginalized. Cirrhosis etiology was ascertained by chart review of medical records. Problematic drinking was defined by ≥8 on the Alcohol Use Disorders Identification Test. Multivariable general linear modeling adjusting for age, sex, race/ethnicity, site, pandemic-related stress, and history of anxiety/depressive disorder were conducted. Sensitivity analyses further adjusted for indicators of liver disease severity.

RESULTS

Participants were on average 64.6 years old, 17% female, 58% non-White, 44% with alcohol-associated cirrhosis, and 17% with problematic drinking. Problematic drinking was significantly associated with worse LDQoL scores in the overall scale and in the memory/concentration and health distress subscales. These associations remained significant after adjusting for indicators of liver disease severity, including Model for End-Stage Liver Disease-Sodium score and decompensated cirrhosis status.

CONCLUSIONS

Among patients with cirrhosis, problematic drinking was associated with worse LDQoL, especially in the domains of memory/concentration and health distress. Assessment and awareness of cognitive deficits and negative emotionality within the context of cirrhosis and problematic drinking may help clinicians provide better integrated care for this population.

Understanding Alcohol Relapse in Liver Transplant Patients With Alcohol-Related Liver Disease: A Comprehensive Review

Alcohol-related liver disease (ALD) presents a significant global health concern, with liver transplantation being a crucial intervention for patients in the advanced stages of the disease. However, the persistent risk of alcohol relapse in transplant recipients with ALD remains a formidable challenge. This comprehensive review explores the multifaceted nature of alcohol relapse, from its underlying factors to strategies for prevention. It highlights the importance of rigorous pre-transplant assessments, effective post-transplant interventions, and the role of multidisciplinary care teams in mitigating the risk of relapse. Furthermore, the review underscores the significance of adopting a holistic approach to ALD and transplantation, acknowledging the interconnectedness of medical, psychosocial, and psychological factors. With this holistic approach, we aim to enhance patient outcomes, reduce relapse rates, and ultimately improve the overall quality of life for individuals affected by ALD.

Alcohol use disorder in alcohol-associated liver disease: Two sides of the same coin

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.

"But I didn't drink!": What to do with discordant phosphatidylethanol results

Liver transplantation (LT) teams must be adept at detecting, evaluating, and treating patients' alcohol use, given its prominence among psychological and behavioral phenomena which cause and contribute to liver diseases. Phosphatidylethanol (PEth) is a highly useful alcohol biomarker increasingly recommended for routine use in hepatology and LT. PEth is unique among alcohol biomarkers because of its wide detection window, high sensitivity and specificity, and the correlation of its numerical value with different patterns of alcohol use. Alongside myriad clinical opportunities in hepatology and LT, PEth also confers numerous challenges: little guidance exists about its clinical use; fearing loss of LT access and the reactions of their clinicians and families, candidates and recipients are incentivized to conceal their alcohol use; and liver clinicians report lack of expertise diagnosing and treating substance-related challenges. Discordance between patient self-reported alcohol use and toxicology is yet another common and particularly difficult circumstance. This article discusses the general toxicological properties of PEth; explores possible scenarios of concordance and discordance among PEth results, patient history, and self-reported drinking; and provides detailed clinical communication strategies to explore discordance with liver patients, a key aspect of its use.

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.

Quality standards for the management of alcohol-related liver disease: consensus recommendations from the British Association for the Study of the Liver and British Society of Gastroenterology ARLD special interest group

OBJECTIVE

Alcohol-related liver disease (ALD) is the most common cause of liver-related ill health and liver-related deaths in the UK, and deaths from ALD have doubled in the last decade. The management of ALD requires treatment of both liver disease and alcohol use; this necessitates effective and constructive multidisciplinary working. To support this, we have developed quality standard recommendations for the management of ALD, based on evidence and consensus expert opinion, with the aim of improving patient care.

DESIGN

A multidisciplinary group of experts from the British Association for the Study of the Liver and British Society of Gastroenterology ALD Special Interest Group developed the quality standards, with input from the British Liver Trust and patient representatives.

RESULTS

The standards cover three broad themes: the recognition and diagnosis of people with ALD in primary care and the liver outpatient clinic; the management of acutely decompensated ALD including acute alcohol-related hepatitis and the posthospital care of people with advanced liver disease due to ALD. Draft quality standards were initially developed by smaller working groups and then an anonymous modified Delphi voting process was conducted by the entire group to assess the level of agreement with each statement. Statements were included when agreement was 85% or greater. Twenty-four quality standards were produced from this process which support best practice. From the final list of statements, a smaller number of auditable key performance indicators were selected to allow services to benchmark their practice and an audit tool provided.

CONCLUSION

It is hoped that services will review their practice against these recommendations and key performance indicators and institute service development where needed to improve the care of patients with ALD.

Improving alcohol treatment engagement using integrated behavioral interventions in alcohol-associated liver disease: A randomized pilot trial

INTRODUCTION

Alcohol cessation improves mortality in alcohol-associated liver disease (ALD), but few ALD patients will engage in treatment. We aimed to demonstrate the feasibility and acceptability of a mobile health intervention to increase alcohol use disorder (AUD) treatment among ALD patients.

METHODS

We conducted a pilot randomized controlled trial (September 2020 to June 2022) at a single tertiary care center in adults with any stage of ALD, past 6-month drinking, and no past-month AUD treatment. Sixty participants were randomized 1:1 to a mobile health application designed to increase AUD treatment engagement through preference elicitation and matching to treatment and misconception correction. Controls received enhanced usual care. The primary outcomes were feasibility (recruitment and retention rates) and acceptability. Exploratory outcomes were AUD treatment engagement and alcohol use, measured by Timeline Followback. Outcomes were measured at 3 and 6 months.

RESULTS

Baseline characteristics were balanced. The recruitment rate was 46%. Retention was 65% at 6 months. The intervention was highly acceptable to participants (91% were mostly/very satisfied; 95% felt that the intervention matched them well to AUD treatment). Secondary outcomes showed increased AUD treatment at 6 months in the intervention group (intent-to-treat: 27.3% vs. 13.3%, OR 2.3, 95% CI, 0.61-8.76). There was a trend toward a 1-level or greater reduction in World Health Organization (WHO) drinking risk levels in the intervention group (OR 2.25, 95% CI, 0.51-9.97).

CONCLUSIONS

A mobile health intervention for AUD treatment engagement was highly feasible, acceptable, and produced promising early outcomes, with improved AUD treatment engagement and alcohol reduction in ALD patients.

Progress of research on the role of active ingredients of Citri Reticulatae Pericarpium in liver injury

BACKGROUND

Liver is a vital organ responsible for metabolizing and detoxifying both endogenous and exogenous substances in the body. However, it is susceptible to damage from chemical and natural toxins. The high incidence and mortality rates of liver disease and its associated complications impose a significant economic burden and survival pressure on patients and their families. Various liver diseases exist, including cholestasis, viral and non-viral hepatitis, fatty liver disease, drug-induced liver injury, alcoholic liver injury, and severe end-stage liver diseases such as cirrhosis, hepatocellular carcinoma (HCC), and cholangiocellular carcinoma (CCA). Recent research has shown that flavonoids found in Citri Reticulatae Pericarpium (CRP) have the potential to normalize blood glucose, cholesterol levels, and liver lipid levels. Additionally, these flavonoids exhibit anti-inflammatory properties, prevent oxidation and lipid peroxidation, and reduce liver toxicity, thereby preventing liver injury. Given these promising findings, it is essential to explore the potential of active components in CRP for developing new drugs to treat liver diseases.

OBJECTIVE

Recent studies have revealed that flavonoids, including hesperidin (HD), hesperetin (HT), naringenin (NIN), nobiletin (NOB), naringin (NRG), tangerine (TN), and erodcyol (ED), are the primary bioactive components in CRP. These flavonoids exhibit various therapeutic effects on liver injury, including anti-oxidative stress, anti-cytotoxicity, anti-inflammatory, anti-fibrosis, and anti-tumor mechanisms. In this review, we have summarized the research progress on the hepatoprotective effects of HD, HT, NIN, NOB, NRG, TN, ED and limonene (LIM), highlighting their underlying molecular mechanisms. Despite their promising effects, the current clinical application of these active ingredients in CRP has some limitations. Therefore, further studies are needed to explore the full potential of these flavonoids and develop new therapeutic strategies for liver diseases.

METHODS

For this review, we conducted a systematic search of three databases (ScienceNet, PubMed, and Science Direct) up to July 2022, using the search terms "CRP active ingredient," "liver injury," and "flavonoids." The search data followed the PRISMA standard.

RESULTS

Our findings indicate that flavonoids found in CRP can effectively reduce drug-induced liver injury, alcoholic liver injury, and non-alcoholic liver injury. These therapeutic effects are mainly attributed to the ability of flavonoids to improve liver resistance to oxidative stress and inflammation while normalizing cholesterol and liver lipid levels by exhibiting anti-free radical and anti-lipid peroxidation properties.

CONCLUSION

Our review provides new insights into the potential of active components in CRP for preventing and treating liver injury by regulating various molecular targets within different cell signaling pathways. This information can aid in the development of novel therapeutic strategies for liver disease.

Management of alcohol use disorder in patients with chronic liver disease

Alcohol use disorder (AUD) rates have risen dramatically in the United States, resulting in increasing rates of alcohol-associated liver disease (ALD), but many patients struggle to access alcohol use treatment. AUD treatment improves outcomes, including mortality, and represents the most urgent means by which care can be improved for those with liver disease (including ALD and others) and AUD. AUD care for those with liver disease involves 3 steps: detecting alcohol use, diagnosing AUD, and directing patients to alcohol treatment. Detecting alcohol use can involve questioning during the clinical interview, the use of standardized alcohol use surveys, and alcohol biomarkers. Identifying and diagnosing AUD are interview-based processes that should ideally be performed by a trained addiction professional, but nonaddiction clinicians can use surveys to determine the severity of hazardous drinking. Referral to formal AUD treatment should be made, especially where more severe AUD is suspected or identified. Therapeutic modalities are numerous and include different forms of one-on-one psychotherapy, such as motivational enhancement therapy or cognitive behavior therapy, group therapy, community mutual aid societies (such as Alcoholics Anonymous), inpatient addiction treatment, and relapse prevention medications. Finally, integrated care approaches that build strong relationships between addiction professionals and hepatologists or medical providers caring for those with liver disease are crucial to improving care for this population.

Alcohol use disorder in community management of chronic liver diseases

Rising rates of alcohol use disorder (AUD) combined with increases in alcohol-related liver disease (ALD) and other liver disease have resulted in the need to develop alcohol management strategies at all levels of patient care. For those with pre-existing liver disease, whether ALD or others, attention to alcohol use treatment and abstinence becomes critical to avoiding worsening liver-related consequences. Modalities to help patients reduce or stop alcohol include screening/brief intervention/referral to treatment, various therapeutic modalities including cognitive behavioral therapy, motivational enhancement therapy and 12-step facilitation, and alcohol relapse prevention medications. Harm reduction approaches versus total abstinence may be considered, but for those with existing ALD, particularly advanced ALD (cirrhosis or acute alcoholic hepatitis), total abstinence from alcohol is the recommendation, given clear data that ongoing alcohol use worsens mortality and liver-related morbidity. For certain populations, alcohol cessation is even more critically important. For those with hepatitis C or NAFLD, alcohol use accelerates negative liver-related outcomes. In women, alcohol use accelerates liver damage and results in worsened liver-related mortality. Efforts to integrate AUD and liver disease care are urgently needed and can occur at several levels, with establishment of multidisciplinary ALD clinics for fully integrated co-management as an important goal.

Therapeutic targets in alcohol-associated liver disease: progress and challenges

Alcohol-associated liver disease (ALD) is a complex disease with rapidly increasing prevalence. Although there are promising therapeutic targets on the horizon, none of the newer targets is currently close to an Food and Drug Administration approval. Strategies are needed to overcome challenges in study designs and conducting clinical trials and provide impetus to the field of drug development in the landscape of ALD and alcoholic hepatitis. Management of ALD is complex and should include therapies to achieve and maintain alcohol abstinence, preferably delivered by a multidisciplinary team. Although associated with clear mortality benefit in select patients, the use of early liver transplantation still requires refinement to create uniformity in selection protocols across transplant centers. There is also a need for reliable noninvasive biomarkers for prognostication. Last but not the least, strategies are urgently needed to implement integrated multidisciplinary care models for treating the dual pathology of alcohol use disorder and of liver disease for improving the long-term outcomes of patients with ALD.

Substance use disorders in organ transplantation: perennial challenges and interprofessional opportunities

PURPOSE OF REVIEW

The current article examines recent publications regarding ongoing clinical and ethical challenges and opportunities related to substance use disorders (SUD) in solid organ transplantation (SOT) utilizing a lens of interprofessional clinical models and care delivery.

RECENT FINDINGS

Innovative interprofessional clinician skillsets and care models are increasingly emphasized in the SOT literature as the standard of care for common, complex psychosocial problems like substance use and SUD. Cannabinoids are common among candidates and recipients and present several unique quandaries to SOT teams. Opioid use disorder treatment can often be definitively treated with medications that SOT teams may find unfamiliar, controversial, or aversive. Arguably the quintessential example of SUD in SOT, early liver transplantation for patients with alcohol-related liver disease and short periods of sobriety has become increasingly common and accepted in recent years requiring liver teams to rapidly acquire significant interprofessional psychiatric awareness and expertise. The question of retransplantation in patients who have experienced recurrent SUD remains unsettled.

SUMMARY

Regardless of substances used or organs transplanted, interprofessional care continues to emerge as a foundational aspect of clinical care and research in SOT.
