A notable proportion of liver transplant candidates with alcohol-related cirrhosis can be delisted because of clinical improvement

Pharmacologic Treatment of Portal Hypertension

Portal hypertension is the key mechanism driving the transition from compensated to decompensated cirrhosis. In this review, the authors described the pathophysiology of portal hypertension in cirrhosis and the rationale of pharmacologic treatment of portal hypertension. We discussed both etiologic and nonetiologic treatment of portal hypertension and the specific clinical scenarios how nonselective beta-blocker can be used in patients with cirrhosis. Finally, the authors summarized the evidence for emerging alternatives for portal hypertension in patients with cirrhosis.

Evolving trends and outcomes on the US liver transplant waitlist of alcohol-associated hepatitis patients with very high MELD scores

Liver transplantation (LT) in patients with alcohol-associated hepatitis (AH) has rapidly increased following the coronavirus disease 2019 pandemic and the implementation of the Acuity Circle policy, raising questions of equity and utility. Waitlist mortality among high (≥37) Model for End-Stage Liver Disease LT candidates with AH and post-transplant survival were assessed with a semiparametric survival regression and a generalized linear mixed-effect model with LT centre- and listing date-level random intercepts. These models demonstrate a lower mortality for the candidates listed with AH (adjusted sub-hazard ratio .58_.72_.90 and odds ratio .44_.66_.99) when compared to other diagnoses (autoimmune hepatitis, metabolic dysfunction-associated fatty liver disease and primary biliary cholangitis). Post-LT survival was comparable. This study highlights the limitations of current tools in characterizing the risk of mortality, and thus need for the modifications in prioritizing LT candidates with AH. Policy revision may be needed to ensure equivalent access to LT regardless of diagnosis.

Advancing hepatic recompensation: Baveno VII criteria and therapeutic innovations in liver cirrhosis management

The Baveno VII criteria redefine the management of decompensated liver cirrhosis, introducing the concept of hepatic recompensation marking a significant departure from the conventional view of irreversible decline. Central to this concept is addressing the underlying cause of cirrhosis through tailored therapies, including antivirals and lifestyle modifications. Studies on alcohol, hepatitis C virus, and hepatitis B virus-related cirrhosis demonstrate the efficacy of these interventions in improving liver function and patient outcomes. Transjugular intrahepatic portosystemic shunt (TIPS) emerges as a promising intervention, effectively resolving complications of portal hypertension and facilitating recompensation. However, optimal timing and patient selection for TIPS remain unresolved. Despite challenges, TIPS offers renewed hope for hepatic recompensation, marking a significant advancement in cirrhosis management. Further research is needed to refine its implementation and maximize its benefits. In conclusion, TIPS stands as a promising avenue for improving hepatic function and patient outcomes in decompensated liver cirrhosis within the framework of the Baveno VII criteria.

Recompensation of cirrhosis in candidates of transplant: Tips and tricks for delisting

Liver transplantation (LT) is the most successful treatment for patients with decompensated cirrhosis. The availability of effective and safe etiological treatments has altered the natural history of decompensated cirrhosis. Recently, the concept of recompensation has been defined. Patients who achieve recompensation may be removed from the waiting list for LT. Therefore, achieving an etiological cure is the cornerstone in the treatment of patients with decompensated cirrhosis. However, most patients improve their liver function after an etiologic cure, and only a proportion of patients achieve true recompensation after an etiological cure. Some patients maintain a condition of "MELD purgatory," that is, an improvement in the Model for End-Stage Liver Disease score without relevant clinical improvement that prevents delisting and may be even detrimental because lower Model for End-Stage Liver Disease score delays LT. Herein, we review the available evidence regarding recompensation and the management of recompensated patients on the waiting list for LT.

[Control and care structures at transplant centers for patients with ethyltoxic cirrhosis while waiting for a liver transplant: A qualitative survey of practitioners.]

OBJECTIVE

The aim of this study was to record the current care and control structures in place for patients with ethyltoxic liver cirrhosis while being prepared for a liver transplant (LTX) at German transplant centers. In addition, it was also intended to analyze the associated barriers as well as the view of the practitioners on ways to improve care of this patient group.

METHODS

In an exploratory descriptive qualitative design, 11 interviews with practitioners from 10 of the 22 German LTX centers were conducted and analyzed using qualitative content analysis.

RESULTS

There were considerable differences in the care and control structures in place at the LTX centers. Addiction therapy counseling or treatment were not integrated into the treatment concept at all centers. Structural barriers arose from insufficient funding and staffing. Practitioners recommended expansion of treatment options as well as standardizing treatment concepts.

DISCUSSION

The results of our study point to a need for action both in the area of the structures of the individual LTX centers and overall at the system level. Taking into account current standards of addiction medicine, our results could serve as a basis for the development of treatment concepts and recommendations for optimizing standard care before LTX.

Evaluation of potential hepatic recompensation criteria in patients with PBC and decompensated cirrhosis

BACKGROUND

Aetiological therapy improves liver function and may enable hepatic recompensation in decompensated cirrhosis.

AIMS

We explored the potential for recompensation in patients with decompensated primary biliary cholangitis (PBC) - considering a biochemical response to ursodeoxycholic acid (UDCA) according to Paris-II criteria as a surrogate for successful aetiological treatment.

METHODS

Patients with PBC were retrospectively included at the time of first decompensation. Recompensation was defined as (i) resolution of ascites and hepatic encephalopathy (HE) despite discontinuation of diuretic/HE therapy, (ii) absence of variceal bleeding and (iii) sustained liver function improvement.

RESULTS

In total, 42 patients with PBC with decompensated cirrhosis (age: 63.5 [IQR: 51.9-69.2] years; 88.1% female; MELD-Na: 13.5 [IQR: 11.0-15.0]) were included and followed for 41.9 (IQR: 11.0-70.9) months after decompensation. Seven patients (16.7%) achieved recompensation. Lower MELD-Na (subdistribution hazard ratio [SHR]: 0.90; p = 0.047), bilirubin (SHR per mg/dL: 0.44; p = 0.005) and alkaline phosphatase (SHR per 10 U/L: 0.67; p = 0.001) at decompensation, as well as variceal bleeding as decompensating event (SHR: 4.37; p = 0.069), were linked to a higher probability of recompensation. Overall, 33 patients were treated with UDCA for ≥1 year and 12 (36%) achieved Paris-II response criteria. Recompensation occurred in 5/12 (41.7%) and in 2/21 (9.5%) patients with vs. without UDCA response at 1 year, respectively. Recompensation was linked to a numerically improved transplant-free survival (HR: 0.46; p = 0.335). Nonetheless, 4/7 recompensated patients presented with liver-related complications after developing hepatic malignancy and/or portal vein thrombosis and 2 eventually died.

CONCLUSIONS

Patients with PBC and decompensated cirrhosis may achieve hepatic recompensation under UDCA therapy. However, since liver-related complications still occur after recompensation, patients should remain under close follow-up.

Acute and non-acute decompensation of liver cirrhosis (47/130)

In the traditional view, the occurrence of cirrhosis-related complications, such as hepatic encephalopathy, formation of ascites or variceal haemorrhage, marks the transition to the decompensated stage of cirrhosis. Although the dichotomous stratification into a compensated and decompensated state reflects a prognostic water-shed moment and remains to hold its prognostic validity, it represents an oversimplification of clinical realities. A broadening understanding of pathophysiological mechanisms underpinning decompensation have led to the identification of distinct prognostic subgroups, associated with different clinical courses following decompensation. Data provided by the PREDICT study uncovered three distinct sub-phenotypes of acute decompensation (AD). Moreover, acute-on-chronic liver failure (ACLF) has been established as a distinct clinical entity for many years, which is associated with a high short-term mortality. Recently, non-acute decompensation (NAD) has been proposed as a distinct pathway of decompensation, complementing current concepts of the spectrum of decompensation. In contrast to AD, NAD is characterized by a slow and progressive development of complications, which are often presented at first decompensation and/or in patients in an earlier stage of chronic liver disease. Successful treatment of AD or NAD may lead to a clinical stabilization or even the concept of recompensation. This review aims to provide an overview on current concepts of decompensation and to delineate recent advances in our clinical and pathophysiological understanding.

Workup and management of liver transplantation in alcohol-related liver disease

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

Recompensation in cirrhosis: unravelling the evolving natural history of nonalcoholic fatty liver disease

Recompensation has gained increasing attention in the field of cirrhosis, particularly in chronic liver disease with a definite aetiology. The current global prevalence of obesity and nonalcoholic fatty liver disease (NAFLD) is increasing, but there is currently a lack of a clear definition for recompensation in NAFLD-related cirrhosis. Here, we provide an up-to-date perspective on the natural history of NAFLD, emphasizing the reversible nature of the disease, summarizing possible mechanisms underlying recompensation in NAFLD, discussing challenges that need to be addressed and outlining future research directions in the field. Recompensation is a promising goal in patients with NAFLD-related cirrhosis, and further studies are needed to explore its underlying mechanisms and uncover its clinical features.

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.

Prognostic models in alcohol-related liver disease and alcohol-related hepatitis

Alcohol-associated liver disease (ALD) and alcohol-associated hepatitis (AH) are dynamic disorders whose prognosis can be challenging to determine. A number of prognostic models have been developed to determine likelihood of death, when to refer for liver transplant (LT) and the role for glucocorticoids. Often these models were created with a specific application in mind but were found to have additional applications with further study. Those prognostic models that have stood the test of time are easy to use, have clear interpretations and employ objective parameters. These parameters most often include total bilirubin, INR and creatinine among other data points. Ideally, these models could be utilized at all phases of disease but in most, it is important for clinicians to consider drinking history and how it might alter the determined scores. Herein we provide a brief review of prognostic models in ALD and AH and provide practical tips and considerations to successfully make use of these tools in a clinical setting.

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.

Hepatic recompensation according to Baveno VII criteria is linked to a significant survival benefit in decompensated alcohol-related cirrhosis

BACKGROUND & AIMS

Removing the primary aetiological factor in decompensated cirrhosis may lead to a restoration of hepatic function. In this study, we investigated the clinical implications of recompensation and the subsequent survival in patients with decompensated alcohol-related cirrhosis.

METHODS

The rate of recompensation was evaluated in patients with decompensated alcohol-related cirrhosis and persistent alcohol abstinence undergoing a hepatic venous pressure gradient (HVPG) measurement. Recompensation was defined according to Baveno VII criteria as resolution of ascites and hepatic encephalopathy, absence of variceal bleeding and improvement in liver function.

RESULTS

Two hundred and four abstinent patients with decompensated alcohol-related cirrhosis (age: 57.2 [IQR:50.1-63.7] years; 75.0% male; median MELD: 15 [IQR:11-19]) and a median HVPG of 20 (IQR:18-24) mmHg were included. During a median follow-up of 24.4 (IQR:10.9-50.4) months, 37 patients (18.1%) achieved abstinence-induced recompensation. Lower baseline HVPG, lower Child-Pugh score, lower BMI, higher albumin and higher mean arterial pressure were linked to a higher probability of recompensation. After adjusting for age, disease severity, portal hypertension and systemic inflammation, achieving recompensation resulted in a significant and considerable reduction in liver-related mortality (adjusted HR: 0.091 [95% CI: 0.012-0.677]; p = .019). Only 13 patients (6.4%) developed hepatocellular carcinoma, with a tendency towards a lower risk upon recompensation (HR: 0.398 [95% CI: 0.084-1.878]; p = .245), yet this finding did not reach statistical significance and requires further investigation.

CONCLUSIONS

Alcohol abstinence led to recompensation in 18.1% of our cohort of HVPG-characterised patients with decompensated alcohol-related cirrhosis. Achieving hepatic recompensation resulted in a >90% risk reduction in liver-related mortality.

The dual role dilemma of liver transplantation health care professionals

BACKGROUND

Similar to many other countries, in Germany patients with alcohol-related liver disease are obliged to prove their abstinence before being accepted on a waitlist for liver transplantation. Health care professionals (HCPs) must both treat patients and ensure that patients have proven their abstinence. The aim of this exploratory study was to develop a deeper understanding of how HCPs deal with this dual role.

METHODS

The study used semi-structured interviews as the source of data. 11 healthcare professionals from ten of the 22 German transplant centers were interviewed. After transcription, a qualitative content analysis was performed.

RESULTS

We found that these HCPs faced an ethical dilemma, as they must balance the roles of being both a treatment provider (the therapist role) and an assessor (the monitoring role). To solve this dilemma, the strategy seems to be a tendency for the HCPs to take on one dominant role amongst these two roles. HCPs who prefer to take on the therapist role seem to feel burdened by the 6-month abstinence rule and the obligation to monitor their patients. HCPs who prefer to take on the monitoring role tend to have negative assumptions about the patients. HCPs also reported the impression that patients perceive HCPs as more involved in monitoring and less open to the therapeutic role. From this it can be deduced that current regulations and structures lead both to stress for HCPs and to suboptimal therapy for those affected.

CONCLUSIONS

The results showed that current transplantation guidelines can have a negative impact on both patient care and the burdens on the HCPs. From our point of view, there are various changes that could be made to the current clinical practice that would help solve this dilemma. For instance, integrating other assessment criteria that are more closely adapted to the health status trajectory and psychosocial background of the individual patient would be both possible and would lead to improvements in practice.

Development and validation of a nomogram to predict recompensation in HBV-related cirrhosis with ascites as the single first decompensating event

BACKGROUND AND OBJECTIVE

Little is known about the influencing factors for recompensation in HBV-related cirrhosis patients with ascites as the single first decompensating event and it's necessary to build a prediction model for these patients.

METHODS

Hepatitis B virus-related cirrhosis patients with ascites hospitalized for the first decompensation were included and they were divided into the training cohort (2010.03-2020.03) and the validation cohort (2020.04-2022.04). All patients received antiviral therapy within 3 months before admission or immediately after admission. Recompensation is defined as the patient's ascites disappeared without diuretics, which were maintained for more than 1 year and no other decompensated complications, hepatocellular carcinoma, or liver transplantation occurred. The nomogram was developed from a training cohort of 279 patients and validated in another cohort of 72 patients.

RESULTS

Totally, 42.7% of the decompensated patients achieved recompensation. According to the results of logistic regression and competing risk analysis, six independent factors associated with recompensation were found and these factors comprised the nomogram: age, alanine aminotransferase (ALT), albumin (ALB), serum sodium (Na), alpha-fetoprotein (AFP), and maintained virological response (MVR). Through external validation, the area under the receiver operating characteristic curve (AUC) of the nomogram was 0.848 (95% CI: 0.761, 0.936), which was significantly better than CTP, MELD, MELDNa, MELD 3.0, and ALBI grade.

CONCLUSIONS

Age, ALT, ALB, Na, AFP, and MVR are closely related to the recompensation. The nomogram developed based on these items can accurately predict the possibility of recompensation in hepatitis B cirrhosis patients with ascites as the single first decompensating event.

Early liver transplantation for severe acute alcohol-related hepatitis after more than a decade of experience

In patients with severe acute alcohol-related hepatitis not responding to medical therapy, early liver transplantation (LT) represents the only effective therapy and, when performed within strict and well-defined protocols, it is associated with a clear survival benefit and acceptable rates of return to alcohol use after transplantation. However, there is still high variability in access to LT for patients with severe alcohol-related hepatitis, mainly due to a persistent overemphasis in the pre-LT evaluation on duration of pre-transplant abstinence and the stigma that patients with alcohol-related liver disease often experience, leading to marked inequity of access to this potentially lifesaving procedure and negative health outcomes. Therefore, there is an increasing need for prospective multicentre studies focusing on pre-transplant selection practices and on better interventions to treat alcohol use disorder after LT.

Recompensation in Cirrhosis: Current Evidence and Future Directions

The natural history of cirrhosis has usually been conceptualized in the context of progression from compensated cirrhosis to subsequent stages of decompensation. While this unidirectional concept is the most common pathophysiological trajectory, there has been an emerging understanding of a subgroup of patients which undergo recompensation. While literature mostly based on transplant waitlist registries have indicated towards such a population who experience disease regression, the overall literature about this entity remains inexplicit. An effort to generate consensus on defining recompensation has been attempted which comes with its own nuances and limitations. We summarize the available literature on this emerging yet controversial concept of recompensation in cirrhosis and delve into future implications and impact on real-life practice.

The Baveno VII concept of cirrhosis recompensation

Traditionally, the progression from compensated to decompensated cirrhosis has been regarded as a point of no return in the natural history of the disease. However, this point of view is increasingly being challenged by new evidence on disease regression and hepatic recompensation upon suppression/cure of the underlying aetiology. In order to create a uniform definition of recompensated cirrhosis, standardised criteria have been set out by the Baveno VII consensus, which include the removal of the primary aetiological factor, the resolution of any decompensating events and a sustained improvement in hepatic function. Initial insights into the concept of hepatic recompensation come from previous studies, which have demonstrated that a cure/suppression of the underlying aetiology in patients with prior decompensation leads to significant clinical improvements and favourable outcomes and can even enable the delisting of transplant candidates. Nevertheless, future studies are required to shed light on the natural history of hepatic recompensation, assess modifying factors and potential non-invasive biomarkers of recompensation and explore the molecular mechanisms of disease regression.

Liver Transplantation in Alcohol-related Liver Disease and Alcohol-related Hepatitis

Alcohol-related liver disease (ARLD) remains one of the leading causes of chronic liver disease and the prevalence of alcohol-related cirrhosis is still increasing worldwide. Thus, ARLD is one of the leading indications for liver transplantation (LT) worldwide especially after the arrival of direct-acting antivirals for chronic hepatitis C infection. Despite the risk of alcohol relapse, the outcomes of LT for ARLD are as good as for other indications such as hepatocellular carcinoma (HCC), with 1-, 5-, and 10- year survival rates of 85%, 74%, and 59%, respectively. Despite these good results, certain questions concerning LT for ARLD remain unanswered, in particular because of persistent organ shortages. As a result, too many transplantation centers continue to require 6 months of abstinence from alcohol for patients with ARLD before LT to reduce the risk of alcohol relapse even though compelling data show the poor prognostic value of this criterion. A recent pilot study even observed a lower alcohol relapse rate in patients receiving LT after less than 6 months of abstinence as long as addictological follow-up is reinforced. Thus, the question should not be whether LT should be offered to patients with ARLD but how to select patients who will benefit from this treatment.

The potential role of machine learning in modelling advanced chronic liver disease

The use of artificial intelligence is rapidly increasing in medicine to support clinical decision making mostly through diagnostic and prediction models. Such models derive from huge databases (big data) including a large variety of health-related individual patient data (input) and the corresponding diagnosis and/or outcome (labels). Various types of algorithms (e.g. neural networks) based on powerful computational ability (machine), allow to detect the relationship between input and labels (learning). More complex algorithms, like recurrent neural network can learn from previous as well as actual input (deep learning) and are used for more complex tasks like imaging analysis and personalized (bespoke) medicine. The prompt availability of big data makes that artificial intelligence can provide rapid answers to questions that would require years of traditional clinical research. It may therefore be a key tool to overcome several major gaps in the model of advanced chronic liver disease, mostly transition from mild to clinically significant portal hypertension, the impact of acute decompensation and the role of further decompensation and treatment efficiency. However, several limitations of artificial intelligence should be overcome before its application in clinical practice. Assessment of the risk of bias, understandability of the black boxes developing the models and models' validation are the most important areas deserving clarification for artificial intelligence to be widely accepted from physicians and patients.

Natural History of Alcohol-Associated Liver Disease: Understanding the Changing Landscape of Pathophysiology and Patient Care

Alcohol use and consequent liver disease are major burdens that have worsened during the COVID-19 pandemic. There are several facets to the pathophysiology and clinical consequences of alcohol-use disorder (AUD) and progression to alcohol-associated liver disease (ALD) that require a concerted effort by clinicians and translational and basic science investigators. Several recent advances from bedside to bench and bench to bedside have been made in ALD. We focused this review on a case-based approach that provides a human context to these important advances across the spectrum of ALD.

Rising Trend in Waitlisting for Alcoholic Hepatitis With More Favorable Outcomes Than Other High Model for End-stage Liver Disease in the Current Era

BACKGROUND

In the appropriate candidate, liver transplantation (LT) is a viable treatment for alcoholic hepatitis (AH). We compared the waitlisting trends and outcomes of AH patients in the context of others with high Model for End-stage Liver Disease (MELD) score.

METHODS

LT listings for AH between January 1, 2008, and June 12, 2020 were identified in the United Network for Organ Sharing database. Temporal trends in listings for AH were assessed. Covariate adjusted competing risks models evaluated waitlist mortality and LT rates between AH candidates and others with listing native MELD ≥30.

RESULTS

Between 2008 and 2019, waitlist additions for AH increased 6.5-fold. Waiting time for AH candidates was short (median 10 d). Delisting for clinical improvement was infrequent in AH, albeit higher than MELD ≥30 patients (3.3% versus 0.8%; P < 0.001). Among 99 centers with ≥1 AH listing, AH patients accounted for 0.2%-18.2% of all alcohol-related listings and 0.6%-25.0% of those with native listing MELD ≥30. Overall listing volume was larger at these 99 centers than the 40 with no AH listings (P < 0.001). AH candidates in 2014-2020 experienced improved waitlist survival (adjusted subhazard ratio, 0.67; 95% confidence interval, 0.52-0.86; P = 0.002) and higher transplant rates (adjusted subhazard ratio, 1.14; 95% confidence interval, 1.04-1.25; P = 0.006) versus other MELD ≥30 candidates.

CONCLUSIONS

There has been a rising trend in waitlisting patients with AH and high MELD score. Liver disease causes influence waitlist outcomes and those of AH candidates are more favorable. Further research and allocation adjustments may be needed to ensure equitable organ allocation, based on liver disease cause, for those on the LT waitlist.

Direct Alcohol Biomarkers Prediction Capacity on Relapse and Mortality in Liver Transplantation Candidates: A Follow-Up Study

Liver transplantation is a complex procedure that requires multiple evaluations, including abstinence monitorization. While literature assessing the impact of different variables on relapse, survival, and graft loss exists, little is known about the predictive capacity of direct alcohol biomarkers. The primary aim of this study was to evaluate the prediction capacity of direct alcohol biomarkers regarding patient survival and clinical relapse. We hypothesized that patients screening positive for any of the experimental biomarkers would show an increased risk of clinical alcohol relapse and death. We conducted a retrospective data recollection from medical files of patients awaiting liver transplantation, who were at baseline screened with Peth, EtG in hair and urine, and EtS. We tested the prediction capacity of the biomarkers with two Cox-regression models. A total of 50 patients were included (84% men, mean age 59 years (SD = 6)). Biomarkers at baseline were positive in 18 patients. The mean follow-up time for this study was 26 months (SD = 10.4). Twelve patients died, liver transplantation was carried out in 12 patients, and clinical relapse was observed in eight patients. The only significant covariate in the Cox-regression models was age with clinical relapse, with younger patients being at greater risk of relapse. This study could not find a significant prediction capacity of direct alcohol biomarkers for mortality or clinical relapse during follow-up. Higher sample sizes might be needed to detect statistically significant differences. All in all, we believe that direct alcohol biomarkers should be widely used in liver transplantation settings due to their high sensitivity for the detection of recent drinking.
