Alcohol use following liver transplantation for alcoholic cirrhosis

Alcohol relapse and its predictors after liver transplantation for alcoholic liver disease: a systematic review and meta-analysis

BACKGROUND

Alcoholic liver disease (ALD) is the leading cause of liver transplantation (LT). The magnitude and risk factors of post-LT alcohol relapse are not well described. We conducted a meta-analysis to evaluate alcohol relapse rate and its predictors after LT.

METHODS

Searches of MEDLINE and SCOPUS identified eligible published studies of alcohol relapse after LT published up to 31 March 2018. Alcohol relapse was defined as any alcohol consumption post-LT, and heavy alcohol relapse was defined as a relapse of alcohol consumption that was associated with a significant harm. Data for the proportion of alcohol relapse was pooled using a meta-analysis for pooling proportion. An odds ratio (OR) of the predictor of alcohol relapse was extracted and pooled using meta-analysis for the pooling risk factor. Data were analyzed using a random effect model if heterogeneity was presented; otherwise, a fixed effect model was applied. The study was registered at PROSPERO (CRD42017052659).

RESULTS

Ninety-two studies with over 8000 cases were recruited for pooling proportion of alcohol relapse. The alcohol relapse rate and heavy alcohol relapse rate after LT during the mean follow-up time of 48.4 ± 24.7 months were 22% (95% confidence interval (CI): 19-25%) and 14% (95%CI: 12-16%). Psychiatric comorbidities (odds ratio (OR) 3.46, 95%CI: 1.87-6.39), pre-transplant abstinence of less than 6 months (OR 2.76, 95%CI: 2.10-3.61), unmarried status (OR 1.84, 95%CI: 1.39-2.43), and smoking (OR 1.72, 95%CI: 1.21-2.46) were associated with alcohol relapse after LT. However, we noticed publication bias of unpublished negative studies and high heterogeneity of results.

CONCLUSIONS

Post-transplant alcohol relapse occurred in about one-fifth of patients who underwent alcohol-related LT. Psychiatric comorbidities represented the strongest predictor of alcohol relapse. Psychiatric comorbidities monitoring and pre-LT alcohol abstinence for at least 6 months may decrease alcohol relapse after LT.

Alcohol or Not: A Review Comparing Initial Mechanisms, Contributing Factors, and Liver Transplantation Outcomes Between Alcoholic and Nonalcoholic Steatohepatitis

Chronic liver diseases take many forms; alcohol-related liver disease (ALD) and nonalcoholic fatty liver disease (NAFLD) are two common illnesses that potentially lead to cirrhosis, liver failure, and liver cancer. It is estimated that a quarter of heavy drinkers develop ALD and the same portion of people without heavy drinking habits have NAFLD. Alcohol intake is regularly used to differentiate NAFLD from ALD; however, diagnosis based on the discrimination threshold may be suboptimal when facing an obese patient with a high level of alcohol exposure. Therefore, understanding the common and/or different mechanism(s) driving each disease is extremely important. The ‘two-hit’ or ‘multi-hit’ hypothesis is used to explain the pathogenesis of both diseases. The ‘first hit’ refers to developing steatosis, the accumulation of fat components in the liver, and the ‘second hits’ are factors leading to oxidative stress, inflammation, and fibrosis, such as metabolic syndromes (e.g., morbid obesity, hyperglycaemia, hyperlipidaemia, disturbed circadian cycles, and altered intestinal microbiota) and environmental toxins (e.g., cigarette smoke and pollutants). Heritable factors also affect the probability and disease progression of both ALD and NAFLD. Whereas PNPLA3 and TM6SF2 variants are influential genetic risk factors for the diseases, epigenetic factors, such as DNA methylation, post-translational histone modifications, and small non-coding RNA, are of paramount importance. Moreover, considering that both ALD and NAFLD patients may eventually develop end-stage liver disease and require liver transplantation, the authors extensively investigated the worldwide outcomes from original literature for these two aetiologies, and the results showed no obvious differences in post-transplantation survival between them. Precise percentage determination of these two aetiologies contributing to steatohepatitis and its secondary injuries in the future would allow for better strategies for therapeutic and preventive intervention.

Self-Management in Liver Transplant Recipients

Introduction:

Although self-management is essential for liver transplant recipients, there is no review that has synthesized findings related to self-management in this population.

Objective:

This narrative review aimed to synthesize the current findings and identify the gaps in knowledge about self-management in liver recipients.

Methods:

A search of PubMed, CINAHL Plus, PsychINFO, ProQuest, and Web of Science was conducted using the following terms: [Self-care OR Self-management OR Health behavior] AND [Liver transplantation]. Peer-reviewed published research articles focusing on self-management of adult recipients were selected. A total of 23 articles were included for review. Two reviewers independently reviewed the full text of selected articles and extracted the data about definitions, measurements, and findings regarding self-management.

Results:

Three areas of self-management were identified, including medication nonadherence (n = 11), alcohol recidivism (n = 11), and health maintenance (n = 5). Reported rates of medication nonadherence ranged from 8% to 66%. Medication nonadherence was related to recipients’ demographic (eg, age or sex), transplant-related (eg, time since transplant), and pretransplant variables (eg, history of substance/alcohol abuse). Reported alcohol recidivism rates ranged from 3% to 95%. Age, pretransplant variables (eg, abstinent time before transplant), and personality disorder were identified to be related to alcohol recidivism after transplant. The health maintenance studies discussed behaviors such as smoking, clinic appointment attendance, or vaccination/health screening behaviors of recipients.

Discussion:

Self-management studies in liver recipients have been narrowly focused on medication nonadherence and alcohol recidivism. To improve self-management in recipients, self-management beyond medication nonadherence and alcohol recidivism should be comprehensively examined.

Late liver function test abnormalities post-adult liver transplantation: a review of the etiology, investigation, and management

Approximately 24,000 liver transplants are performed annually worldwide, almost 7000 of which are performed in the USA. Survival is excellent and continues to improve, with 1-year survival currently exceeding 85 %, but effective management of patients after liver transplantation is critical to achieve optimal results. A plethora of diseases can affect the transplanted allograft, ranging from recurrence of the original disease to de novo liver pathology, and diagnosis can be complicated by nonclassical presentation, de novo disease, or inconclusive histology. Patients can remain asymptomatic despite significant damage to the transplanted liver, so prompt identification and treatment of liver disease after transplantation is crucial to preserve allograft function. Liver function tests are routinely taken throughout the postoperative period to monitor the graft. Although nonspecific, they are inexpensive, noninvasive, and sensitive for allograft disease and can quickly alert physicians to the presence of asymptomatic pathology. This review will outline possible causes of liver function test abnormalities in the late posttransplant period and provide guidance for investigation, diagnosis, and management.

Ethical considerations regarding early liver transplantation in patients with severe alcoholic hepatitis not responding to medical therapy

A recent study proposed that liver transplantation may represent life-saving treatment in patients with severe alcoholic hepatitis not responding to medical therapy. In this pilot experience, stringent patient selection resulted in major improvement of short-term survival with low rates of post-transplant alcohol relapse. In the context of organ shortage, which imposes a need for strict selection of transplant candidates, these results raise major ethical questions. Reluctance to perform liver transplantation in alcoholics is based on the fact that alcoholism is frequently considered to be self-inflicted and on fears of harmful post-transplant alcoholism recurrence. A minimal interval of sobriety lasting at least 6 months is a widely adopted criterion for the selection of patients with alcoholic liver disease for liver transplantation. In severe alcoholic hepatitis, the disastrous short-term prognosis in patients not responding to medical therapy does not allow one to reasonably impose an arbitrary period of 6-months of abstinence. This means that these patients must be either systematically excluded from transplantation or selected according to other criteria. Without significant pre-transplant abstinence, it might be argued that these patients do not merit a graft as they have not demonstrated their ability to gain control over their disease through durable modification of their behaviour. Consequently, this procedure could have a negative impact in the public, affecting organ donation and confidence in the fairness of transplant programs. In contrast, ethical principles recommend active treatment of patients, without discrimination, according to the best scientific knowledge. At this stage, we propose that there are no major ethical barriers for further evaluation of this new therapeutic option. The next steps should include transparent communication with the public and further studies to reproduce these results and identify the selection criteria that provide the best long-term outcomes.

Management of alcoholic hepatitis: Current concepts

Alcoholic hepatitis is a devastating form of acute liver injury seen in chronic alcohol abusers with significant morbidity and mortality. It is a multisystem disease that is precipitated by ingesting large quantities of alcohol with genetic and environmental factors playing a role. Prognostic criteria have been developed to predict disease severity and these criteria can serve as indicators to initiate medical therapy. Primary therapy remains abstinence and supportive care, as continued alcohol abuse is the most important risk factor for disease progression. The cornerstone of supportive care remains aggressive nutritional support, and although acute alcoholic hepatitis has been extensively studied, few specific medical therapies have been successful. Corticosteroids remain the most effective medical therapy available in improving short term survival in a select group of patients with alcoholic hepatitis; however, the long-term outcome of drug therapies is still not entirely clear and further clinical investigation is necessary. While liver transplantation for acute alcoholic hepatitis have demonstrated promising results, this practice remains controversial and has not been advocated universally, with most transplant centers requiring a prolonged period of abstinence before considering transplantation. Extracorporeal liver support devices, although still experimental, have been developed as a form of liver support to give additional time for liver regeneration. These have the potential for a significant therapeutic option in the future for this unfortunately dreadful disease.

Assessing family members' motivational readiness and decision making for consenting to cadaveric organ donation

This study assessed the applicability of two important components of the transtheoretical model of behavior change (TTM) to family consent for cadaveric organ donation. Men and women (N = 169), who consented or refused to donate the organs of a family member, completed a telephone survey reflecting the stage of change and decisional balance constructs. Psychometric analyses resulted in a two-factor decisional balance scale: a seven-item scale representing negative perceptions of consent (cons), and a seven-item scale representing positive perceptions of consent (pros). The pros and cons were significantly associated with stage of readiness for donation consent and with the family consent decision. Research utilizing this measure has the potential to enhance intervention programs to increase donation consent rates.

Pathogenesis and management of alcoholic liver cirrhosis: a review

Little is known about how alcohol causes liver disease and cirrhosis. The strongest evidence of the causality between alcohol and liver disease stems from epidemiological observations. Factors contributing to alcohol-induced fibrosis and cirrhosis include cytokines, oxidative stress, and toxic metabolites of ethanol. Patients with alcoholic cirrhosis generally have complications at diagnosis, and cirrhotic complications should be actively assessed because they are closely associated with subsequent morbidity as well as mortality. Abstinence is strictly required to prevent disease progression and is critical for eventual liver transplantation. In addition, nutritional therapy remains the mainstay of managing alcoholic cirrhosis.

Controversies in the management of alcoholic liver disease

Alcohol is a risk factor for chronic disease burden in developed countries. Alcoholic liver disease affects 1% of the North American population and is the second most frequent indication for liver transplantation in the United States. It is a spectrum that ranges from simple hepatic steatosis to alcoholic hepatitis to steatohepatitis and eventually cirrhosis. The clinical spectrum of alcoholic hepatitis is wide and ranges from the asymptomatic patient to overt liver failure and death. Liver biopsy as a means of prognostication in alcoholic hepatitis has mostly been replaced with less invasive scoring systems. The management of alcoholic liver disease is challenging. Abstinence is the cornerstone of therapy and should include rehabilitation with a multidisciplinary approach. No specific treatment is required in mild to moderate alcoholic hepatitis. In patients with severe hepatitis, there appears to be a moderate survival benefit from the use of either corticosteroids or pentoxifylline in the absence of contraindications to their use. Nonresponders should have steroid therapy withdrawn by day 7, as persistence with therapy is not beneficial. Orthotopic liver transplantation remains the definitive therapy for decompensated alcoholic cirrhosis despite alcohol abstinence. More studies are needed to define the optimal timing of orthotopic liver transplantation and patients at risk of alcohol relapse post-transplant. Mt Sinai J Med 76:484-498, 2009.

Liver transplantation for hepatitis C and alcoholic liver disease

End-stage liver disease due to hepatitis C (HCV) and cirrhosis from alcohol (ALD) are the commonest indications for liver transplantation in the western countries. Up to one third of HCV-infected transplant candidates have a history of significant alcohol intake prior to transplantation. However, there are few data available about the possible interaction between alcohol and HCV in the post-transplant setting. Patients with both HCV and alcohol are more likely to die on the waiting list than those with ALD and HCV alone. However, after transplantation, non-risk adjusted graft and patient survival of patients with HCV + ALD are comparable to those of patients with HCV cirrhosis or ALD cirrhosis alone. In the short and medium term HCV recurrence after transplant in patients with HCV + ALD cirrhosis does not seem more aggressive than that in patients with HCV cirrhosis alone. A relapse in alcohol consumption in patients with HCV + ALD cirrhosis does not have a major impact on graft survival. The evidence shows that, as is currently practiced, HCV + ALD as an appropriate indication for liver transplantation. However, these data are based on retrospective analyses with relatively short follow-up so the conclusions must be treated with caution.

Liver transplantation for alcoholic liver disease

Alcoholic liver disease (ALD) is the second commonest indication for liver transplantation after viral hepatitis in the United States and Europe. Controversies surround the indications and allocation of scarce and expensive resource for this so called self inflicted disease. Controversies stem from the apprehension that alcoholic recipients are likely to relapse and cause damage to the graft. There is a need to select those candidates with lower risk for relapse with the available predictive factors and scores. Substance abuse specialist and psychiatrists are mandatory in the pre-transplant evaluation and in the post-transplant follow-up. There is conflicting evidence to support a fixed period of pretransplant abstinence, although most units do follow this. Alcoholic hepatitis (AH) continues to be a contraindication for transplantation, however there is a need for further research in this field as a subset of patients with AH who do not respond to medical treatment, have high early mortality and could benefit from transplantation. One year, 3-year, and 5-year survival post-transplant is similar for both ALD and non-ALD recipients. The incidence of post-transplant rejection and retransplantation is also similar to other recipients. ALD with viral hepatitis especially hepatitis C virus leads to a more aggressive liver disease with early presentation for transplantation. ALD patients are more prone to develop de-novo malignancy; this is attributed to the long term effect of alcohol, tobacco combined with immunosuppression. Post-transplant surveillance is important to detect early relapse to alcoholism, presence of de-novo malignancy and treat the same adequately.

A critical review of candidacy for orthotopic liver transplantation in alcoholic liver disease

The majority of candidates with end-stage alcoholic liver disease (ESALD) in the United States who are eligible for referral for liver transplantation (LT) are not being referred. There is a lack of firm consensus for the duration of abstinence from alcohol as well as what constitutes good psychosocial criteria for listing for LT. Evidence shows that the general public and the practicing physicians outside the transplant community perceive that patients with a history of alcohol abuse will make poor transplant candidates. However, physicians in the transplant community perceive selected patients with ESALD as good candidates. When considering patients for listing for LT, 3 months of alcohol abstinence may be more ideal than 6 months. Patients with a lack of social support, active smoking, psychotic or personality disorders, or a pattern of nonadherence should be listed only with reservation. Those who have a diagnosis of alcohol abuse as opposed to alcohol dependence may make better transplant candidates. Patients who have regular appointments with a psychiatrist or psychologist in addictions treatment training also seem to do more favorably.

When good organs go to bad people

A number of philosophers have argued that alcoholics should receive lower priority for liver transplantations because they are morally responsible for their medical conditions. In this paper, I argue that this conclusion is false. Moral responsibility should not be used as a criterion for the allocation of medical resources. The reason I advance goes further than the technical problem of assessing moral responsibility. The deeper problem is that using moral responsibility as an allocation criterion undermines the functioning of medicine.

Recidiva da ingesta alcoólica em pacientes candidatos a transplante hepático: análise de fatores de risco

RACIONAL: A recidiva do consumo do álcool após transplante representa grande preocupação nos centros transplantadores e é objeto de debate e controvérsia. OBJETIVO: Avaliar a recidiva da ingesta alcoólica e eventuais fatores a ela relacionados, em pacientes cirróticos, referidos para transplante hepático. MÉTODOS: Estudo retrospectivo de julho de 1995 a setembro de 2005 incluindo 90 pacientes adultos com cirrose hepática, listados para transplante. Os critérios de exclusão eram: ausência de 6 meses de abstinência, não liberação da equipe de psicologia. O diagnóstico da recidiva (ingesta de qualquer quantidade de bebida alcoólica) era feito com base nas informações contidas nos prontuários e fornecidas por contato telefônico. RESULTADOS: A recidiva encontrada foi de 18,9%, que correspondeu a 14,6% do número total de homens e 62,5% do número total das mulheres. A raça, média das idades, classificação de disfunção hepática, tempo de etilismo, quantidade da ingesta alcoólica e realização ou não de transplante, não mostraram correlação significativa com a recidiva da ingesta alcoólica. A comparação tempo de abstinência e recidiva guardou relação inversamente proporcional. CONCLUSÃO: A recidiva da ingesta alcoólica é baixa. Sexo feminino e tempo de abstinência inferior a 1 ano têm influência sobre a recidiva da ingesta alcoólica.

Negative impact of de novo malignancies rather than alcohol relapse on survival after liver transplantation for alcoholic cirrhosis: a retrospective analysis of 305 patients in a single center

OBJECTIVES

Alcoholic liver disease is a leading indication for liver transplantation (LT). The aim of this study was to evaluate long-term results and survival prognostic factors of LT in this indication from a large cohort of patients.

METHODS

From October 1990 to October 2005, 305 consecutive patients with alcoholic cirrhosis (from 594 patients presenting with cirrhosis, i.e., 51.3%) underwent LT in our center. There were 229 men and 76 women, with a median age of 50 yr (range 30-68). Clinical and biological variables with possible prognostic value were analyzed.

RESULTS

Global survival rate was 92.6% at 1 yr, 88.5% at 3 yr, 84.3% at 5 yr, and 73.4% at 10 yr, and was similar (P=0.78, log-rank test) to that of patients transplanted for other cirrhosis (88.8% at 1 yr, 84.1% at 3 yr, 80.6% at 5 yr, and 74.7% at 10 yr). Recurrence of alcohol consumption was observed in 37 patients (12.1%). De novo cancer occurred in 35 patients after LT (11.5%). Univariate analysis disclosed that male gender, history of smoking, and de novo carcinoma were significant survival prognostic factors (P<0.05, log-rank test).

CONCLUSIONS

Our results strongly confirm that alcoholic liver disease is an excellent indication for LT, but long-term survival is reduced because of other target-organ damage of both alcohol and tobacco, especially aero-digestive malignancies, which are greater causes of morbidity and mortality than is recurrent alcohol liver disease.

[Stabilisation of abstinence by means of psychoeducation for patients with alcoholic liver disease awaiting liver transplantation]

BACKGROUND

A manualised six-month psychoeducational intervention was conducted in patients with alcoholic liver disease and abstinence problems who were waiting for a transplantation.

OBJECTIVES

In a naturalistic design it was investigated whether the intervention could improve patients' alcohol abstinence.

METHODS

Between January 2002 and November 2003, 72 patients were enrolled in the therapeutic intervention, 48 of whom participated in group therapy. Health-related quality of life (SF-12), anxiety and depression (HADS-D), symptom strain (BSI) and social support (F-SOZU) were measured. Alcohol abstinence was examined in each group session by measuring the alcohol concentration in breath.

RESULTS

At the beginning and end of the group therapy patients showed subsyndromal measures of anxiety and depression and minor symptoms of psychopathology. Physical quality of life was reduced (t = -8.694; df = 44; p < .001). Mental quality of life was in the range of the normative sample and was correlated with depression (r = -0.400; p = .009). Patients perceived high social support (t = 8.213; df = 45; p < .001). During the course of therapy four patients had relapses but the remaining patients stayed abstinent. Physical quality of life improved (t = -2.275; df = 27; p = .031), mental quality of life and symptom strain remained stable.

CONCLUSIONS

The therapy presented here facilitated a stabilisation of mental well-being in patients with alcoholic liver disease who were waiting for organ transplantation. The relapse rate measured by alcohol concentration in breath remained low.

The impact of pathologist experience on liver transplant biopsy interpretation

We studied the impact of pathologist experience on liver transplant biopsy interpretation for cases designated 'nonspecific' by pathologists at a nontransplant center. Among 102 consecutive liver transplant biopsies from 92 patients performed at the Foothills Medical Center, 30 liver biopsies from 23 patients were designated 'nonspecific' by the local pathologist. These biopsy slides were independently reviewed by an expert in liver transplant pathology at a major US transplant center. The expert pathologist was given only the information on the original requisition. In seven biopsies from five patients, there was full agreement between the external expert and the local pathologist. In 10 biopsies from six patients, the expert concurred with the initial assessment but emphasized critical negatives such as 'no evidence of rejection or recurrent hepatitis'. A discrepant diagnosis was found in 13 biopsies from 12 patients. In five biopsies from four patients, the revised diagnoses were inaccurate due to insufficient or misleading clinical information on the requisition. In eight biopsies from eight patients, the revised diagnoses were proven to be correct by clinicopathologic correlation. Our study shows that pathology expertise helped to clarify the diagnosis in about 27% of cases, which justifies the cost of obtaining a second opinion in difficult biopsies. Misinterpretation by the expert pathologist in up to 17% of biopsies highlights the importance of direct communication between hepatologist and pathologist in order to achieve a correct diagnosis. Familiarity with those cases with relatively uncommon histology, a diligent search for subtle morphologic changes, and use of standard terminology could improve the quality of liver transplant biopsy interpretation in a nontransplant center.

Liver transplantation for alcoholic liver disease: a systematic review of psychosocial selection criteria

AIMS

To examine the evidence base for psychosocial selection criteria for liver transplant candidates with alcoholic liver disease.

METHOD

Systematic review using three electronic databases supplemented by hand searches.

RESULTS

Out of 96 published studies, 22 were included. All but one were cohort design, most were retrospective, single centre, and small sample. Methodology varied considerably, such that meta-analysis was not feasible.

CONCLUSIONS

Social stability, no close relatives with an alcohol problem, older age, no repeated alcohol-treatment failures, good compliance with medical care, no current polydrug misuse, and no co-existing severe mental disorder have all been associated with future abstinence in more studies than not, in those that examined these variables. Duration of preoperative abstinence was a poor predictor. We recommend that, if predicting future abstinence is considered necessary by transplant teams, a standardized approach is agreed and deployed amongst transplant units, then audited and reviewed.

Are preoperative patterns of alcohol consumption predictive of relapse after liver transplantation for alcoholic liver disease?

Predictive factors for alcoholic relapse after liver transplantation (LT) performed for alcoholic liver disease (ALD) have been assessed in numerous studies, often with contradictory results. The aim of the study was to assess pretransplantation alcohol consumption characteristics on alcoholic relapse after LT. Patients transplanted for ALD for at least 6 months were included. An anonymous questionnaire assessed socio-demographic characteristics, medical history, and alcohol consumption before and after LT. Relapse was defined as any alcohol use after LT. Severe relapse was defined by heavy drinking: more than 21 units/week for males and 14 units/week for females. A total of 61 patients were studied. The mean follow up after LT was 49 +/- 34 months. Alcoholic relapse occurred in 32 of 61 patients (52%) and severe relapse in eight of 61 patients (13%). Risk factors for severe relapse were: length of abstinence before LT (P = 0.0001), more than one alcohol withdrawal before LT (P = 0.001), alcohol dependence (P = 0.05), alcohol abuse in first relatives (P = 0.05), and younger age (P = 0.05). Information on previous alcohol consumption (dependence, number of withdrawals, family history) helps to predict severe relapse after LT in patients with ALD, allowing early awareness and specific postoperative care.

Evaluation for liver transplantation: adherence to AASLD referral guidelines in a large Veterans Affairs center

Access of patients to liver transplantation involves three levels: referral for evaluation for transplantation, placement on a waiting list for transplantation, and receipt of a liver transplant. No study has formally evaluated access to liver transplantation at the referral level. Therefore, we sought to estimate the magnitude and determinants of consideration of liver transplantation in patients at a single, large Veterans Affairs medical center. Patients with liver disease were identified between October 2002 and September 2003, and their entire medical records were examined for encounters involving potential indications for liver transplantation according to American Association for the Study of Liver Diseases (AASLD) guidelines, mention of liver transplantation, and potential contraindications. Liver transplantation was mentioned in only 59 (20%) of 300 encounters, constituting 41 (21%) of 199 patients satisfying AASLD guidelines for referral. The significant negative independent determinants of mention of liver transplantation were older age (adjusted odds ratio [OR]: 0.31; 95% confidence interval [CI]: 0.13-0.77, P = 0.01), alcoholic liver disease (adjusted OR: 0.10; 95% CI: 0.02-0.57, P = 0.01), and black race (OR: 0.15; 95% CI: 0.02-0.96, P = 0.045). Most patients had potential contraindications that were inferred (but not documented) as reasons for not being evaluated for transplantation; however, a small but significant proportion (7%) had no recorded evidence of contraindications. In conclusion, we found a low rate of mention of liver transplantation in patients who satisfied AASLD guidelines for referral, particularly among patients with alcoholic liver disease and blacks. Deficiencies at the referral level may lead to disparities at further levels of access to liver transplantation.

Alcohol recidivism impairs long-term patient survival after orthotopic liver transplantation for alcoholic liver disease

The aim of this study was to evaluate the rate of alcohol recidivism after orthotopic liver transplantation (OLT) for alcoholic liver disease (ALD) and its influence on the allograft and patient survival, as well as the development of comorbidities and de novo cancers. The study was performed on 54 subjects previously analyzed and transplanted in our center for ALD, whose follow-up was prolonged to a mean of 99.2 (SD 31.7) months (range, 14-155). Medical records were reviewed, and data on alcohol consumption, therapeutic compliance, graft evolution, rejection, infections, comorbidities, rates of de novo malignancies and other clinical events, and survival were collected. Comparisons between groups were performed by the Fisher's exact test, and survival was assessed by the Kaplan-Meier method. Survival curves were compared using the Mantel-Cox statistic. The risk of death resulting from alcohol recidivism was analyzed with a Cox proportional hazards model. Fourteen patients who underwent transplantation for ALD (25.9%) returned to alcohol use between 5.0 and 86.9 months after OLT (median, 47.5). There was no significant association between the presence or absence of alcohol recidivism and the occurrence of graft rejection, infections, associated comorbidities after OLT, or compliance. The 5- and 10-year survival rates for patients with alcohol recidivism were 92.9% and 45.1%, respectively, compared with 92.4% and 85.5%, respectively, for patients without alcohol recidivism. These figures show significantly lower survival rates in recidivistic patients after 10 years (P < 0.01, Mantel-Cox). The fact that patients who resumed alcohol consumption have a worse 10-year survival rate might be attributed to a higher frequency of deaths, primarily from cancer and cardiovascular events.

Liver transplantation for alcoholic liver disease

Patients with end-stage alcoholic liver disease should be considered for liver transplantation. A careful pretransplant evaluation must be undertaken to assess for both medical and psychiatric factors that will continue to require attention following transplantation. Although most programs require at least 6 months of ethanol abstinence before consideration of liver transplantation, there is little evidence that this conclusively predicts a reduction in recidivism. Most programs continue to exclude those with alcoholic hepatitis. Postoperatively, attention to psychiatric issues, recidivism, compliance, and assessment for tumors, especially squamous cell carcinomas, should be undertaken.

Transplantation hépatique chez l’adulte

Liver transplantation allows to treat patients with end-stage cirrhosis as well as some liver malignancies (small size hepatocellular carcinoma) with a life expectancy exceeding 70 and 60 % at 5 years, respectively. Current immunosuppressive agents make it possible to prevent chronic rejection in more than 90 % of the patients and to preserve an excellent quality of life in most cases. The principal limiting factor for liver transplantation is represented by the scarcity of brain-dead donors. Indeed, despite the selection of those candidates who have the best chance of surviving after transplantation, several months are usually necessary for obtaining a graft and the mortality on the waiting list may reach 10 to 15 %. Organ shortage incited to develop alternatives to conventional transplantation, the most important of which are living donor transplantation and split liver transplantation. Living donor transplantation can be applied to about 20 to 30 % of candidates. Thought initially smaller, the partial graft regenerates and its volume is restored within a few weeks. The results of living donor transplantation in terms of survival are comparable to those of cadaveric transplantation. The risk for the donor has to be lower than 1 % which makes that selection must be especially cautious. Donors must be direct relatives or spouses. Split liver transplantation technique, based on the separation of a cadaveric graft into two functional parts transplanted in two distinct recipients, although attractive, is applicable to less than 25 % of the donors. Education for organ donation in the general population still remains a priority.

Pretransplant screening of sobriety with carbohydrate-deficient transferrin in patients suffering from alcoholic cirrhosis

Sufficient assessment of potential candidates for orthotopic liver transplantation (OLT) is the most important factor for a low alcohol relapse rate after transplantation in patients suffering from alcoholic cirrhosis. In the current study the efficiency of pretransplant screening with carbohydrate-deficient transferrin (CDT) was analysed in patients on the waiting list for OLT. A prospective study was performed in 44 patients who had undergone OLT for alcoholic cirrhosis. All patients had had pretransplant assessment by a specialist psychologist and were found to have no problems with alcohol. Pre- and post-transplant CDT monitoring was performed. Overall, 790 CDT values were measured in the study population. The median observation period was 2.1 months before and 41.2 months after transplantation, respectively. In 35 patients (80%) pretransplant CDT values were found to be above the reference value, but only one patient suffered an alcohol relapse after transplantation. Of the nine patients (20%) who demonstrated normal CDT before transplantation, two suffered an alcohol relapse after transplantation. CDT is a very useful marker for the monitoring of an alcohol relapse in patients following OLT for alcoholic cirrhosis, as has been previously indicated. However, CDT does not appear to be useful as a pretransplant screening marker for selection of potential transplant candidates suffering from alcoholic cirrhosis.

Liver transplantation for alcoholic liver disease: current concepts and length of sobriety

1. The 1-year and 5-year actuarial survival rates following liver transplantation for patients with alcoholic liver disease are 82% and 68%, respectively, in the United States and 85% and 70%, respectively, in Europe. These survival rates are similar to the outcomes of patients who undergo transplantation for other types of chronic liver disease. 2. Posttransplant improvements in health-related quality of life are similar in patients who undergo transplantation for alcoholic liver disease compared to those who undergo transplantation for other causes of end-stage liver disease. 3. Approximately 20% of patients who undergo transplantation for alcoholic liver disease use alcohol posttransplant, with one-third of these individuals exhibiting repetitive or heavy drinking. Surprisingly, little evidence exists to document a significant detrimental effect on graft or patient survival associated with resumption of drinking. 4. There are few reliable predictors of relapse in alcoholic patients after liver transplantation. Although not supported by all studies, abstinence of fewer than 6 months prior to transplantation may be a reasonable predictor of recidivism and is widely employed as a criterion for listing for liver transplantation. There are no good data to determine if some patients with sobriety fewer than 6 months might benefit from liver transplantation.

Societal reintegration after liver transplantation: findings in alcohol-related and non-alcohol-related transplant recipients

OBJECTIVE

To compare the degree of societal reintegration between alcohol-related and non-alcohol-related liver transplant recipients.

SUMMARY BACKGROUND DATA

Orthotopic liver transplantation (OLTX) is the treatment of choice for end-stage liver disease of various etiologies. Returning patients to society to lead active and productive lives is a key goal of OLTX.

METHODS

A questionnaire assessing societal reintegration was administered by phone to 84 alcoholic liver disease (ALD) OLTX recipients (ALDs) and 68 non-ALD OLTX recipients having undergone OLTX at a single-center urban not-for-profit teaching hospital. Sixty-eight non-ALD OLTX recipients, serving as the control group (Controls), were matched to the ALDs by age, sex, and length of follow-up. Participation levels were assessed in the following areas: employment, homemaking, academic study, support of others through financial and/or care-giving efforts, and involvement in social or community groups and activities.

RESULTS

Seventy-nine percent of ALDs and 81% of Controls were male. Median age was 53 years for ALDs and 54 years for Controls. Median length of follow-up for both groups separately was 52 months. No significant differences were noted between ALDs and Controls in the proportion of employed individuals, homemakers, students, and supporters of others. Controls were significantly more likely than ALDs to be involved in structured social activities and routine volunteer work.

CONCLUSIONS

Alcohol-related and non-alcohol-related OLTX recipients appear to return to society to lead similarly active and productive lives. ALD OLTX recipients appear less likely to be involved in structured social activities and routine volunteer work than non-ALD OLTX recipients.

Alcohol relapse after liver transplantation for alcoholic liver disease: does it matter?

BACKGROUND/AIMS

The aim of this study was to distinguish the types of alcohol consumption after liver transplantation (LT) for alcoholic cirrhosis and to assess the consequences of heavy drinking.

METHODS

Patients transplanted for alcoholic cirrhosis were studied. Alcoholic relapse diagnosis was based upon patient's and family members' reports, liver enzyme tests, graft biopsy, and use of urine alcohol test.

RESULTS

One hundred twenty-eight patients were studied, with a mean follow-up of 53.8 months. After LT, 69% of patients were abstinent, 10% were occasional drinkers, and 21% were heavy drinkers. Actuarial survival rates were not different, but three of the seven deaths observed among heavy drinkers were directly related to alcohol relapse. Although there was no difference between the three groups concerning the rejection rates, all rejection episodes observed in the group of heavy drinkers were related to poor compliance with immunosuppressive drugs. One heavy drinker developed alcoholic cirrhosis.

CONCLUSIONS

The present study indicates that patients can resume heavy alcohol consumption after LT for alcoholic liver disease (ALD) and their grafts can be injured because of poor compliance with immunosuppressive drugs and alcohol-related liver injury. Although patient survival was not influenced by alcohol relapse, heavy alcohol consumption can be responsible for patients' death.

[Outcome of liver transplantation in patients with alcoholic liver disease]

BACKGROUND

Liver transplantation is accepted as effective therapeutic option for end-stage liver disease, including alcoholic liver disease

AIM

To evaluate the outcome of liver transplantation for alcoholic liver disease in the Liver Transplantation Program at "Hospital de Clínicas" of the Federal University of Paraná, Curitiba, PR, Brazil.

PATIENTS AND METHODS

It was performed a retrospective study of the patients who underwent liver transplantation for alcoholic end-stage liver disease between September 1991 and January 2001. The minimum abstinence period required was 6 months before liver transplantation. Identification of alcohol consumption after liver transplantation was determinated by information provided by patient or family and biochemical or histological anormalities.

RESULTS

Twenty patients underwent liver transplantation for alcoholic liver disease in the study period, 95% (19/20) were men and the median age was 50 years (29-61 years). Seventy-five percent of the patients (15/20) had severe liver disfunction (Child C class) in the pre-transplant period. In six of them (30%) there was association with viral hepatitis and in one, with hepatocarcinoma. Median abstinence period before liver transplantation was 24 months, varying from 9 to 120 months. One-year and 3-year survival rate were 75% and 50%, respectively. The main complications were: acute cellular rejection (40%), chronic rejection (5%), hepatic artery thrombosis (15%), biliary complications (15%), bacterial or fungal infections (45%), cytomegalovirus infection (20%). Three patients returned to alcohol use after liver transplantation

CONCLUSION

The survival of patients who received liver transplant for alcoholic cirrhosis are satisfactory. In the present study there was a small index of alcohol use after liver transplantation.

Indication of liver transplantation in severe alcoholic liver cirrhosis: quantitative evaluation and optimal timing

BACKGROUND/AIMS

The aim of our study was to evaluate the proportion of patients with severe alcoholic cirrhosis who would need orthotopic liver transplantation (OLT) and to determine the optimal delay to evaluate an abstinent patient for transplantation.

METHODS

Survival without OLT, improvement in liver function and need for OLT were studied in all patients admitted in 1997 for a first episode of Child-Pugh C alcoholic cirrhosis.

RESULTS

Twenty-six percent (19/74) of patients died during the initial hospitalization. The cumulative survival rates after 6 months and 1, 2 and 3 years were 56, 36, 35 and 24%, respectively. One liver transplantation (1.3%, 95% confidence interval 0.0-3.9) was performed for persisting liver failure despite abstinence. Improvement of the Child-Pugh score was observed within 3 months in 66% of the abstinent patients. OLT was indicated in four patients without liver improvement despite abstinence, but was contraindicated in three.

CONCLUSIONS

Only a few patients with severe alcoholic cirrhosis undergo OLT, since most of them do not stop drinking and/or die soon, and those becoming abstinent often improve their liver function. OLT should be considered when improvement in liver function is lacking after 3 months of abstinence.

Liver transplantation for alcoholic liver disease

Although increasing numbers of alcoholic patients are being referred to liver transplant centres, liver transplantation for alcoholic liver disease still remains controversial, essentially because we are in an era of organ shortage. In fact, the main issue is the likelihood of relapse and its influence on outcome, because it is the possibility of returning to alcohol use that separates patients with alcoholic liver disease from those with other forms of chronic liver disease. In all proposed clinical guidelines of indications for referral and assessment for liver transplantation for alcoholic liver disease, the authors emphasize the risk of alcoholism recurrence and, thus, a multidisciplinary approach is required to select patients who are likely to comply with follow-up and not return to a damaging pattern of alcohol consumption after transplantation. It emerges from all clinical studies that when we take into account the usual criteria of success for liver transplantation, i.e. patient and graft survival, rejection rate and infection rate, alcoholic liver disease is a good indication for liver transplantation. Predictive factors for alcoholic relapse after liver transplantation have been assessed in numerous studies, often with contradictory results making these difficult to analyse and compare. Several predictive factors for alcoholic relapse have been studied: length of abstinence before transplantation, associated psychiatric problems, social conditions, associated drug addiction, age. Abstinence after transplantation is the goal, but the necessary treatment for alcoholic disease can result in considerable improvement, even when complete abstinence is not achieved. Finally, the good results obtained with liver transplantation for alcoholic liver disease should help us to educate the general population about alcoholic disease.

Risk factors for failure to meet listing requirements in liver transplant candidates with alcoholic cirrhosis

BACKGROUND

The majority of liver transplant centers require a 6-month abstinence period before listing candidates for liver transplantation with alcoholic cirrhosis and a persistent sobriety thereafter. We attempted to identify risk factors for failure to comply with these requirements.

METHODS

Ninety-nine consecutive patients with alcoholic cirrhosis were referred for liver transplant evaluation between September 1996 and May 1998. The mean age was 49 years, 74% were male, and 54% were hepatitis C virus positive. To be listed, patients had to meet the following requirements. All patients received extensive psychosocial evaluations and were frequently monitored with random urine and blood alcohol tests; patients found positive were excluded or removed from the liver transplant waiting list. Detailed patient information was entered into a computerized database, and 36 discreet variables were analyzed in relation to success (patient listed and remained on the list) or failure (not listed or removed from the list based on noncompliance).

RESULTS

Forty-nine patients were successfully listed. Nineteen received a transplant, with a 95% 1-year patient and graft survival rate and 21% alcohol relapse rate after transplantation. Twenty-two patients had either medical contraindication and/or died before transplant listing. Twenty-four patients were never listed and four were removed from the list due to recurrent alcoholism, for a total of 28 failures. Our statistical analysis identified five significant risk factors for failure: (I) living arrangement (alone/family versus community/friend), P=0.006; (II) history of suicide ideation, P=0.03; (III) history of previous alcohol-related hospitalization, P=0.01; (IV) lack of previous alcoholic rehabilitation before transplant evaluation, P=0.001; and (V) failure to accept further alcoholic rehabilitation before orthotopic liver transplantation, P=0.01.

CONCLUSIONS

Our experience confirms that transplantation can be extremely successful in properly selected patients with alcoholic cirrhosis. We identified several predictive psychosocial factors of early alcoholic recidivism in transplant candidates.

Histological features after liver transplantation in alcoholic cirrhotics

BACKGROUND/AIMS

Though alcoholic cirrhosis is a common indication for liver transplantation, it carries the risk of alcohol recidivism and consequent graft failure. This study aims to evaluate the effect of alcohol recidivism on survival rates and histological parameters in patients transplanted for alcoholic cirrhosis, with and without hepatitis C virus (HCV) infection.

METHODS

Fifty-one out of 189 consecutive transplanted patients underwent psychosocial evaluation and liver biopsy at 6 and 12 months, then yearly after transplantation.

RESULTS

The cumulative 84 month survival rate was identical in patients transplanted for alcoholic (51%) and non-alcoholic cirrhosis (52%). No difference emerged between anti-HCV negative vs. positive alcoholic cirrhosis patients. Psycho-social evaluation revealed alcohol recidivism in 11/34 long-term survivors, but this did not affect overall survival rate in patients with or without HCV. In anti-HCV negative cases, fatty changes and pericellular fibrosis were significantly more common in heavy drinkers than in occasional drinkers and abstainers. When HCV status was considered regardless of alcohol intake, fibrosis was significantly more frequent in patients with HCV.

CONCLUSION

Alcohol recidivism after transplantation in alcoholic cirrhosis patients does not affect survival, irrespective of HCV status. Fatty changes and pericellular fibrosis are the most relevant histological signs of heavy alcohol intake.

Orthotopic liver transplantation for alcoholic liver disease: a retrospective analysis of survival, recidivism, and risk factors predisposing to recidivism

The aim of this study performed at the Liver Unit at the Queen Elizabeth Hospital, Birmingham, UK, is to assess posttransplantation alcohol consumption and identify risk factors associated with recidivism. This retrospective case-control study used a self-report questionnaire to assess pretransplantation and posttransplantation drinking, and a retrospective cohort study used patient notes to analyze risk factors for recidivism. Of 64 patients who underwent transplantation for alcoholic liver disease (ALD) between May 1996 and November 1999, a total of 49 surviving patients (40 men, 9 women) were available for study. The comparison group consisted of 49 patients matched for age, sex, and date of transplantation who underwent transplantation for non-alcohol-induced chronic liver disease. Two-year patient survival rates were 82% in both study groups. The questionnaire response rate was 69.3% and 75.5% in patients with and without ALD, respectively. Data on recidivism (defined as any alcohol consumption after transplantation) were available in 46 of the 49 patients with ALD. Of these, 45.6% were drinking; 21.7% reported only occasionally drinking; 17.3%, moderate drinking; and 6.5%, heavy drinking. Information on alcohol consumption was available from 41 of the 49 controls. Of these, 52.5% consumed alcohol; 22.0% reported drinking only on special occasions; 24.4%, moderate drinking; and 4.9%, a return to heavy drinking. However, these differences were not statistically significant, and log-rank analysis found no significant difference in time to resumption of drinking. In the ALD cohort, no significant risk factors were identified to predict recidivism. No pretransplantation risk factors (including period of abstinence before transplantation) correlated with recidivism. Survival after transplantation for ALD is similar to that in other forms of chronic liver disease. Recidivism rates for patients with ALD are high, but patients with ALD do not drink more than their control counterparts posttransplantation. In most instances, alcohol consumption posttransplantation is minimal to moderate (<20 units/wk) and seems to be controlled.

Employment and alcohol use after liver transplantation for alcoholic and nonalcoholic liver disease: a systematic review

The purpose of the study is to evaluate patterns of employment and alcohol use among liver transplant recipients with alcoholic (ALD) and nonalcoholic liver disease (non-ALD). MEDLINE, EMBASE, and bibliographic searches identified 5,505 potentially relevant articles published between January 1966 and October 1998. Eighty-two studies reporting data on 5,020 transplant recipients met our inclusion criteria. Pre-orthotopic liver transplantation (OLT), 29% of transplant recipients with ALD and 59% of those with non-ALD worked versus 33% and 80% at 3 years for transplant recipients with ALD and non-ALD, respectively (P <.00001 for each interval). We found no difference in the proportion of transplant recipients with ALD and non-ALD reporting early alcohol use post-OLT: 4% versus 5% at 6 months and 17% versus 16% at 12 months. However, among post-OLT drinkers, transplant recipients with non-ALD were more likely to drink moderately and those with ALD to drink excessively. At 7 years post-OLT, 32% of the patients with ALD reported using alcohol. The odds ratio for alcohol use among patients who maintained abstinence for fewer than 6 months pre-OLT versus those who maintained abstinence for greater than 6 months was 7.8 (95% confidence interval, 4.0 to 15.3). Before OLT and at long-term follow-up, substantially more transplant recipients with non-ALD than ALD were employed. The proportions of transplant recipients with ALD and non-ALD reporting alcohol use did not differ, although those with ALD tended to consume greater quantities.

Quality of life after liver transplantation for alcoholic liver disease

There are few data on predictive factors for alcohol relapse or long-term functional outcome after liver transplantation for alcoholic liver disease (ALD). In all 56 surviving UK patients (47 men, 9 women; mean age: 51 years; range: 33 to 69 years) who underwent transplantation for ALD at King's College Hospital over a 10-year period, alcohol relapse and outcome were assessed by outpatient and case-note review and by postal questionnaire containing (1) the Nottingham Health Profile (NHP), (2) the Short-Form-36 (SF-36) Health Survey, and (3) a drug and alcohol questionnaire. At a median of 2.5 years (range: 0.5 to 10 years), 13 of the 47 respondents (28%) and 2 of the 9 nonrespondents (22%) had evidence of potentially harmful drinking (>3 units daily) at some time posttransplantation. An additional 13 patients admitted to drinking some alcohol at least once, corresponding to an overall relapse rate of 50%. The patients with harmful drinking (1) had started drinking regularly at a younger age (18 v 25 years; P =.01), (2) began drinking heavily at a younger age (30 v 40 years; P =.01), (3) had shorter pretransplantation abstinence periods (10 v 23 months; P =.02), and (4) had a longer time since transplantation (median, 5.7 v 1.5 years; P =.0004) than those with no or mild alcohol relapse. They were also more likely to report sleep disturbance (NHP sleep problem score, 45 v 16; P =.01) and use benzodiazepines regularly (7 of 13 v 3 of 34 patients; P =.002). Despite these differences, health dimension scores in the SF-36 and NHP posttransplantation were similar between the groups and to those of UK community controls. In the long term, at least 50% of the patients will drink again at some time posttransplantation, although at lower levels of alcohol intake than previously. Those patients with multiple predictive factors for alcohol relapse may be at greatest risk for harmful drinking and be the group that would benefit most from professional counseling. Overall, the quality of life after liver transplantation for ALD is high and broadly similar to the levels expected in the normal population.

Interpreting the significance of drinking by alcohol-dependent liver transplant patients: fostering candor is the key to recovery

Few studies have examined the value of treating alcohol addiction either before or after liver transplantation. Nevertheless, most liver transplant programs and many insurance companies require 6 months to 1 year of abstinence from alcohol as a condition of eligibility for liver transplantation (the 6-month rule). We believe there are potentially harsh clinical consequences to the implementation of this rule. For example, the natural history of alcohol use disorders often involves brief fallbacks to drinking ("slips"), but when alcoholic liver transplant candidates slip, most are removed from consideration for transplantation or are required to accrue another 6 months of sobriety. Because there is no alternative treatment to liver transplantation for most patients with end-stage liver disease, the 6-month rule could be lethal in some circumstances. In this review, we survey the literature concerning the ability of the 6-month rule to predict drinking by alcoholic patients who undergo liver transplantation and examine its impact on the health consequences of drinking before and after liver transplantation. We believe that fostering candor between the alcoholic patient and the transplant team is the key to recovery from alcoholism. We conclude that it is unethical to force alcoholic liver patients who have resumed alcohol use while waiting for or after transplantation to choose between hiding their drinking to remain suitable candidates for transplantation or risk death by asking for treatment of alcoholism. Consequently, we advocate a flexible approach to clinical decision making for the transplant professional caring for an alcoholic patient who has resumed drinking and provide specific guidelines for patient management.

Noncompliance in organ transplant recipients: a literature review

The consequences of failing to comply to doctor's instructions can be damaging and devastating for the individual patient and their family. Noncompliance also leads to waste, as it reduces the potential benefits of therapy, and to the extra cost of treating avoidable consequent morbidity. Life-long immunosuppression is a prerequisite for good graft function, and noncompliance is often associated with late acute rejection episodes, graft loss, and death. It might be assumed that transplant patients constitute a highly motivated group, and that compliance would be high. Unfortunately, this is not the case: overall noncompliance rates vary from 20 to 50%. This overview includes literature on heart, liver, and kidney transplants in adult and pediatric transplant patients. Compliance behavior after transplantation, noncompliance and its relationship to organ loss and death, retransplantation outcome after graft loss due to noncompliance, and reasons for postoperative noncompliance will be addressed.

Comparing quality of life following liver transplantation for Laennec's versus non-Laennec's patients

The overall success of orthotopic liver transplantation (OLTX) includes not only survival, but quality of life (QOL) as well. We studied one controversial group of OLTX recipients, patients transplanted for alcoholic liver disease (Laennec's), to determine if their post-OLTX QOL was similar to that of patients transplanted for non-alcoholic liver disease (non-Laennec's). Over a 10-yr period, patients undergoing OLTX at our institution were asked to complete a QOL questionnaire addressing a wide range of topics from demographics and employment to symptom distress/frequency, activities of daily living, and effect of loss of health on daily life. Twenty-four Laennec's and 100 non-Laennec's OLTX recipients completed the questionnaire at both their 2- and 5-yr follow-up visits at our institution. Both groups were well-matched in age, race, and patient location status at the time of OLTX. No significant differences could be detected between Laennec's and non-Laennec's scores regarding overall QOL, including one's ability to function, health perception, and self-perception at 2 and 5 years post-OLTX, and between 2 and 5 years post-OLTX. Although not between groups, a significant difference was noted regarding patients' satisfaction with life, with less satisfaction reported at the 5-yr versus the 2-yr time point post-OLTX. Rates of current/recent employment between both groups were also similar at 2 years post-OLTX, and again at 5 years post-OLTX. We conclude that overall QOL and employment levels appear similar between patients transplanted for alcoholic and non-alcoholic liver disease. This similarity appears to extend to 5 years post-OLTX.

Late-onset renal failure after liver transplantation: role of posttransplant alcohol use

BACKGROUND

Late-onset renal failure is being increasingly recognized as a complication in patients undergoing liver transplantation for hepatitis C virus (HCV). However, its precise incidence, predisposing risk factors, and impact on outcome after liver transplantation, have not been defined.

METHODS

The development of late-onset renal failure (defined as serum creatinine persistently >2.0 mg/dl, occurring more than 6 months posttransplant) was assessed in 120 consecutive liver transplant recipients who survived at least 6 months after transplantation. Fifty-seven percent (68/120) of the patients had undergone transplantation for liver disease due to HCV. The median follow-up was 5 years.

RESULTS

Late-onset renal failure developed in 28% (33/120)of the patients. Posttransplant alcohol use (P=0.0001), posttransplant diabetes (P=0.0042), and recurrent HCV hepatitis (P=0.019) were significantly associated with late onset renal failure. In multivariate analysis, alcohol use (O.R. 10.7, 95%; CI 2.4-35.9, P=0.001) and diabetes (O.R. 2.1, 95%; CI 1.1-9.9, P=.03) were independently significant predictors of late onset renal failure. When only patients transplanted for HCV were analyzed, posttransplant alcohol use (P=0.004) was the only significant independent predictor of late-onset renal failure. HCV genotype 1b, as compared with other HCV genotypes, was associated with a higher rate of late-onset renal failure in patients with HCV; 70% of the patients with genotype 1b versus 32% of those with 1a and 33% of those with 2b, developed late onset renal failure (P=0.03). At a median follow up of 5 years, mortality in patients with HCV with late-onset renal failure was 52% as compared with 2% in those without renal failure (P=.0001).

CONCLUSION

Late-onset renal failure in patients with HCV portended a grave outcome. Alcohol use was an independent predictor of late-onset renal failure in patients with HCV and represents a potentially modifiable risk factor for late-onset renal failure in these patients.

Allocating livers to substance and alcohol misusers

The success of liver transplantation for the treatment of patients with end-stage liver disease has resulted in a widening gap between the number of potential recipients and the numbers of grafts available. Allocation of these scarce resources to people who have developed liver failure as a consequence of their own and often illegal behaviour has attracted much controversy. For patients with alcoholic liver disease, there is relatively little evidence that many patients return to a damaging pattern of alcohol consumption and, at least in the short term, the outcome is no different compared with patients grafted for other causes of cirrhosis. There are well-validated markers which predict abstinence. For abusers of other substances, there is relatively little experience. Of concern is the variation between the priority-setting by the medical profession and the general public. The latter, who, in the UK, can be considered as providers of the donated organs and pay for the costs of the procedure, tend to rate patients with alcoholic liver disease and who have drug or substance abuse at a lower priority than those who develop liver failure from other causes. These differences need further debate and resolution.

Rapidly progressive liver injury and fatal alcoholic hepatitis occurring after liver transplantation in alcoholic patients

Alcohol-related liver disease (ALD) is a common indication for orthotopic liver transplantation (OLT) in adults. Although return to 'heavy drinking' post-OLT is believed to be uncommon, the prevalence and severity of alcohol-related liver injury in such patients is not well characterized. We retrospectively reviewed the records of 68 adult patients who underwent OLT for ALD to determine the incidence of return to heavy drinking and to assess their clinical outcome. Follow-up ranged from 8-99 months (mean 42) post-OLT; 54 patients were followed for > or = 12 months. Ten patients (15%) had evidence of coexisting viral hepatitis (hepatitis C in 9 and hepatitis B in 1) before OLT. Six of 68 patients (8%) returned to heavy drinking post-OLT, and three of those died of alcoholic hepatitis at nine months, 2.5 and 3.5 years after OLT. In two of these three patients, premortem liver biopsy showed histologic features of alcoholic hepatitis in addition to bridging fibrosis or cirrhosis. None of the three patients who died of ALD had coexisting viral hepatitis. Of the 57 patients surviving for > or = 3 months post-OLT, 4 of 8 patients (50%) with steatosis and Mallory bodies in their native livers returned to heavy drinking compared to only 2/49 (4%) without these histologic findings (P<0.05). In conclusion, the incidence of heavy drinking post-OLT was uncommon, however, it was associated with fatal alcoholic hepatitis in 50% of patients. Rapidly progressive alcohol-related liver injury was seen even in the absence of coexisting viral hepatitis. The presence of steatosis and Mallory bodies in the native liver, which suggests recent or ongoing alcohol-related liver injury, predicted a return to heavy drinking post-OLT.
