Drinking behavior and motivation for treatment among alcohol-dependent liver transplant candidates

Clinical Utility and Impact of Phosphatidylethanol Testing in Liver Transplantation Evaluations

BACKGROUND

Phosphatidylethanol (PEth) is a serum biomarker that can detect alcohol use within the last 28 days with excellent sensitivity and specificity. Urinary ethyl glucuronide (uEtG) is commonly used in transplant settings to screen for alcohol use; however, it has several limitations relevant to liver transplantation. Transplant centers are beginning to regularly utilize PEth as part of the screening process for high-risk liver transplantation candidates although the clinical utility of uniform pre-transplant PEth testing is unclear.

METHODS

This was a retrospective chart review of all patients evaluated for liver transplantation from December 1, 2019, through May 31, 2022, at a large academic tertiary referral center utilizing uniform serum PEth and uEtG screening. Information regarding the patients' transplantation status, age, sex, race, Model for End-Stage Liver Disease score, and PEth levels was obtained. In those with a positive PEth, we examined if the result would have been detected with uEtG, identified a discrepancy from the documented patient report of last use, led to a change in the Psychosocial Assessment of Candidate for Transplantation score, or influenced the transplant selection committee's decision.

RESULTS

Our sample included 865 individuals (mean age = 55.20, 61.27% male and 82.54% white) with calculated Model for End-Stage Liver Disease-Sodium scores ranging from 6.43 to 50.65 (mean: 18.09; median: 16.46). Forty-eight patients were found to have a positive PEth (PEth range 20-1833); 75% of the sample had alcohol-associated liver disease. In 23 of 48 (47.91%) cases, the positive PEth identified alcohol use missed by a concomitant uEtG screen. A positive PEth test identified a discrepancy from patients' self-report in 29 (60.42%) cases and influenced the selection committee's decision in 28 cases (58.33%).

CONCLUSION

Uniform pretransplant PEth screening of liver transplant candidates at the time of initial evaluation identified alcohol use that would have been missed by uEtG testing, identified discrepancies from the patient's self-report, and influenced clinical decision-making in a significant number of cases. These findings support the use of uniform PEth screening in liver transplantation evaluations.

Treating Alcohol Use Disorder in Patients with Alcohol-Associated Liver Disease: Controversies in Pharmacological Therapy

Alcohol use disorder (AUD) is one of the main causes of global death and disability. The liver represents the main target of alcohol damage, and alcohol-associated liver disease (ALD) represents the first cause of liver cirrhosis in Western countries. Alcohol abstinence is the main goal of treatment in AUD patients with ALD, as treatments for ALD are less effective when drinking continues. Moreover, the persistence of alcohol consumption is associated with higher mortality, increased need for liver transplantation, and graft loss. The most effective treatment for AUD is the combination of psychosocial interventions, pharmacological therapy, and medical management. However, the effectiveness of these treatments in patients with ALD is doubtful even because AUD patients with ALD are usually excluded from pharmacological trials due to concerns on liver safety. This narrative review will discuss the treatment options for AUD-ALD patients focusing on controversies in pharmacological therapy.

Alcohol and other substance use after liver transplant

In this article we tackle the controversial subject of alcohol and other substance use following liver transplantation (LT). Most of the literature on and importance of this topic pertains not to recreational use of alcohol or substances but to patients who have alcohol or substance use disorders (AUDs/SUDs). To understand these behaviors after such a lifesaving and resource-intensive procedure as LT necessitates an understanding of these disorders as chronic medical diseases. It also requires an awareness that management of these disorders begins before transplant, so we will briefly touch on considerations to prepare patients for the transplantation. Additionally, we review not only the rates of alcohol and substance use post-LT but strategies clinicians could adopt to identify and manage these events post-LT. Thus, we will summarize approaches for monitoring use and a range of therapeutic treatment options, including pharmacotherapy, to employ once use is discovered. While clinical gastroenterologists may be the primary clinicians responsible for the care of LT recipients, we emphasize a multidisciplinary team approach which, especially for the behavioral health components of the treatment, is likely to be the most successful. This article concludes with a summary of recommendations for clinicians working with these patients and possible future directions for both clinical care and research. While the bulk of the literature is on LT in the context of AUD, we review the smaller body of literature available on non-alcohol substance use.

Alcohol use disorder and liver transplant: new perspectives and critical issues

Alcoholic liver disease is a consolidated indication for liver transplantation, but many unsolved issues can be highlighted. Patients with alcohol use disorder develop peculiar comorbidities that can become contraindications for transplantation. Moreover, a number of social and psychological patterns should be evaluated to select candidates with a low risk of alcohol relapse and adequate post-transplant adherence. In this context, the 6-month rule is too rigid to be widely applied. A short period of abstinence (1 to 3 months) is useful to estimate recovery of liver function and, possibly to avoid transplant. Cardiovascular disorders and extra-hepatic malignancies represent the main clinical issues after transplant. Patients transplanted due to alcoholic disease are a major risk for other liver diseases. Severe corticosteroid-resistant alcoholic acute hepatitis is a debated indication for transplant. However, available data indicate that well-selected patients have excellent post-transplant outcomes. Behavioral therapy, continued psychological support and a multidisciplinary team are essential to achieve and maintain complete alcohol abstinence during the transplant process. Alcoholic liver disease is an excellent indication for a liver transplant but patients with alcohol use disorder deserve a personalized approach and dedicated resources.

Systematic Review: Treatment for Addictive Disorder in Transplant Patients

BACKGROUND AND OBJECTIVES

The number of patients with substance use disorders in need for organ transplantation is expected to increase. Patients with addictive disorders are considered a higher risk of negative outcomes after organ transplantation due to the impact of substance use upon medical status and adherence with treatment. The goal of this systematic review was to assess the current literature on treatment for addiction transplant candidates and recipients.

METHODS

We conducted a literature search within four databases PubMed, MEDLINE, EMBASE, and PsycINFO for publications dated 1/1/1988 to 12/31/2018.

RESULTS

Out of 3108 articles identified through database screening, 39 were included in the qualitative synthesis. Sixteen studies described addiction treatment in groups over five patients. All the articles included liver transplant patients, with only two studies including patients who needed a kidney or a heart transplant. Nine articles described treatment of alcohol use disorder exclusively, five focused on treatment of opioid use disorders. Although 9 of 16 studies were prospective, the variability of the treatment intervention, outcome measures, and control group when applicable prohibited a meaningful meta-analysis of the results. Eight articles that described the case reports are analyzed separately.

DISCUSSION AND CONCLUSIONS

Promising treatment options for alcohol use disorder have been reported but more studies are needed to confirm their effectiveness and their feasibility. Methadone appears effective for opioid disorder in transplant patients.

SCIENTIFIC SIGNIFICANCE

To the best of our knowledge, this is the first systematic review on the treatment of addictive disorders in transplant patients. (Am J Addict 2020;29:445-462).

Diagnosis and Management of Alcohol Use Disorder in Patients with Liver Disease: Lights and Shadows

Alcohol use disorder is the most common cause of advanced liver disease in the Western world. Diagnosis of alcohol use disorder can be difficult because patients with liver disease tend to deny alcohol intake for the fear of being excluded from treatment and because available biomarkers of alcohol intake have poor specificity in these patients. Alcohol abstinence is the cornerstone of the therapy in these patients. However, pharmacological treatments for alcohol use disorders have not been formally tested in patients with advanced liver disease, except for baclofen. Psychosocial intervention became crucial in these patients considering the limited pharmacological choice. However, psychosocial approach and an appropriate team to manage these patients are not still well defined. In this review, we critically discuss the diagnosis and the management of alcohol use disorder in patients with liver disease.

A review of behavioral alcohol interventions for transplant candidates and recipients with alcohol-related liver disease

Alcohol-related liver disease (ALD) is a common indication for liver transplantation. Reflecting growing consensus that early transplant (ie, prior to sustained abstinence) can be a viable option for acute alcoholic hepatitis, access to liver transplantation for ALD patients has increased. Prevention of alcohol relapse is critical to pretransplant stabilization and posttransplant survival. Behavioral interventions are a fundamental component of alcohol use disorder treatment, but have rarely been studied in the transplant context. This scoping review summarizes published reports of behavioral and psychosocial alcohol interventions conducted with ALD patients who were liver transplant candidates and/or recipients. A structured review identified 11 eligible reports (3 original research studies, 8 descriptive papers). Intervention characteristics and clinical outcomes were summarized. Interventions varied significantly in orientation, content, delivery format, and timing/duration. Observational findings illustrate the importance of situating alcohol interventions within a multidisciplinary treatment context, and suggest the potential efficacy of cognitive-behavioral and motivational enhancement interventions. However, given extremely limited research evaluating behavioral alcohol interventions among ALD patients, the efficacy of behavioral interventions for pre- and posttransplant alcohol relapse remains to be established.

Diagnosis and Treatment of Alcohol Use Disorder in Patients With End-Stage Alcoholic Liver Disease

Between 14%-30% of the world's population is affected by alcohol use disorder (AUD), and excessive alcohol consumption represents the most common cause of liver disease in the western world. The clinical picture of alcoholic end-stage liver disease is rendered extremely complex, as manifestations such as alcohol withdrawal syndrome, craving and physical dependence, as well as extrahepatic alcohol-related diseases merge with the complications of advanced cirrhosis. This makes AUD recognition and assessment difficult and its management arduous as many drugs commonly used to treat complications such as alcohol withdrawal syndrome are often contraindicated by the presence of hepatic encephalopathy or hepatorenal syndrome. Reaching and maintaining abstinence represents the mainstay of managing patients with AUD and end-stage liver disease. Psychosocial interventions are an essential component of treatment to reach these goals. However, these interventions alone often prove insufficient in AUD patients and even more frequently in those with end-stage liver disease because of inadequate adherence due to poor functional and physical status. Pharmacological treatments need to be associated, but the available options are greatly limited in end-stage liver disease because many GABA-Ergic drugs can favor the development of hepatic encephalopathy, whereas drugs undergoing extensive liver metabolism should be avoided or used with the greatest caution. Because of these limitations, the management of end-stage AUD is extremely challenging and requires an integrated multidisciplinary approach.

Text Messaging to Reduce Alcohol Relapse in Prelisting Liver Transplant Candidates: A Pilot Feasibility Study

BACKGROUND

Many liver transplantation programs require documented alcohol sobriety prior to United Network for Organ Sharing (UNOS) listing. This pilot study examined the feasibility of the first mobile, alcohol relapse prevention intervention for liver transplant patients with alcoholic liver disease (ALD).

METHODS

This was a randomized 8-week pilot feasibility trial of a text message-based alcohol intervention. In-treatment assessment was conducted at 4 weeks (4W), and immediate posttreatment assessment was conducted at 8W. Participants were liver transplant candidates (N = 15) diagnosed with ALD who reported at least 1 drinking episode in the past year. Primary feasibility outcomes were percent of messages responded to and posttreatment intervention satisfaction ratings. Preliminary clinical efficacy outcomes were any biologically confirmed alcohol consumption, stress, abstinence self-efficacy, and alcohol craving.

RESULTS

On feasibility outcomes, participants responded to 81% of messages received and reported high rates of intervention satisfaction, looked forward to receiving the messages, and found it easy to complete the intervention. On preliminary efficacy outcomes, zero participants in the text message (TM) had positive urine alcohol tests at 8W. Two of the 6 participants in standard care (SC) tested positive at 8W. No effects were seen on craving. For stress, a condition × time interaction emerged. TM participants had less stress at 4W and 8W compared with SC at baseline. They maintained their stress level during the intervention. For self-efficacy, a trend for condition effect emerged. TM participants had higher self-efficacy than SC participants.

CONCLUSIONS

Participants reported high satisfaction with the intervention, looked forward to the messages, and found it easy to complete. Participants who received the intervention had better treatment outcomes than those who received standard care. They maintained higher levels of self-efficacy and lower stress. Mobile alcohol interventions may hold significant promise to help ALD liver transplant patients maintain sobriety.

Implementation of the High-Risk Alcoholism Relapse Scale in a Liver Transplant Clinic

Because of the high prevalence of alcohol relapse after liver transplantation, transplant programs are challenged to evaluate alcoholism among liver transplant patients. Relapse after liver transplantation can have detrimental outcomes such as organ rejection, medical and social resource exhaustion, financial burden to the family and society, and negative public perception of organ transplantation. The purpose of this project was to improve post-liver transplant assessment for the risk of relapse to heavy alcohol use by implementing a protocol using the High-Risk Alcoholism Relapse (HRAR) scale (DiMartini et al., 2000; Yates et al., 1993). The project was conducted in an urban organ transplant center's outpatient post liver transplant clinic. Chart reviews assessed the process of patients identified as being at high risk and the transplant providers' completion of the HRAR scale. Eleven percent of patients assessed were identified as being at high risk for relapse of heavy alcohol use and 85% of providers used the HRAR scale in their clinic interviews. This project demonstrates that further refinements in techniques of predicting the risks of relapse are necessary, and nurses are in ideal positions to screen patients for alcohol use.

Reluctance to Accept Alcohol Treatment by Alcoholic Liver Disease Transplant Patients: A Qualitative Study

BACKGROUND

Liver transplantation (LT) is the optimum treatment for patients with end-stage alcoholic liver disease (ALD). However, despite a recognized risk of relapse to harmful drinking, ALD transplant patients are reluctant to use speciality alcohol treatment to support their abstinence, even when offered within the LT context. This study aimed to understand and identify factors contributing to alcohol treatment reluctance by ALD patients undergoing transplantation.

METHODS

We conducted an in-depth qualitative study of ALD transplant patients. Minimally structured face-to-face interviews explored participants' alcohol-related experiences and their reasons for not using alcohol treatment during the course of their transplantation. Thematic analysis was used to analyze and interpret interview data to understand treatment reluctance based on participants' experiences.

RESULTS

Five major themes were identified among 3 subgroups of patients (pretransplant and posttransplant abstainers and posttransplant relapsers): (i) the "contract" of mandatory abstinence, (ii) the "gap in the program" involving the lack of candour between patient and staff about alcohol-related matters and the lack of addiction services, (iii) a preference by participants to self-manage their alcohol use disorder, (iv) social support as a facilitator of abstinence and the risk of relapse when social support is diminished, and (v) the fear of stigmatization. Each of these factors were dynamically interrelated and differed slightly for each subgroup.

CONCLUSIONS

The LT services may benefit from the inclusion of integrated specialist addiction services in their model of care. Such an approach may enhance the acceptability of alcohol treatment and reduce the risk of relapse among ALD transplant participants, especially for those whose social supports have diminished.

Liver transplantation for alcoholic liver disease

Alcoholic liver disease (ALD) is the major cause of life-threatening liver disease in Western countries. Abstinence from alcohol is the foundation of all treatment programmes for patients with ALD. Liver transplantation is a valuable option for patients with life-threatening ALD. Although the role of liver transplantation in the treatment of alcoholic hepatitis that is unresponsive to medical therapy is controversial, the latest prospective studies support this approach. No single measure gives a reliable estimate of the risk of drinking relapses before or after liver transplantation, but careful evaluation by an addiction specialist with a particular interest in transplant medicine is the best available approach. Survival, both on the waiting list and after the operation, is better in patients with ALD than in patients with HCV infection. Alcohol relapse may lead to liver damage and increased mortality, albeit usually after many years of renewed drinking. After liver transplantation, patients with ALD have increased rates of mortality and morbidity that are attributable to cardiovascular disease and new-onset cancers of the aerodigestive tract. The latter are probably linked to the high prevalence of smoking in this population. Cessation of smoking is thus an important goal in the care of patients with ALD after they have undergone liver transplantation.

Management of alcohol dependence in patients with liver disease

Alcohol dependence represents a chronic and relapsing disease affecting nearly 10 % of the general population both in the USA and in Europe, with a widespread burden of morbidity and mortality. Alcohol dependence represents the most common cause of liver damage in the Western world. Although alcoholic liver disease is associated primarily with heavy drinking, continued alcohol consumption, even in low doses after the onset of liver disease, increases the risk of severe consequences, including mortality. Consequently, the ideal treatment of patients affected by alcohol dependence and alcoholic liver disease should aim at achieving long-term total alcohol abstinence and preventing relapse. The aim of the present review is to provide an update on the management of alcohol dependence in patients with alcoholic liver disease. Increasing evidence suggests the usefulness of psychosocial interventions and medications combined in order to reduce alcohol intake, promote abstinence and prevent relapse in alcohol-dependent patients. Disulfiram, naltrexone and acamprosate have been approved for this indication; gamma-hydroxybutyric acid (GHB) is approved in Italy and Austria. However, these drugs have not been tested in patients with advanced liver disease. Amongst other emerging pharmacotherapies for alcoholism, topiramate, ondansetron, and baclofen seem the most promising ones. Both topiramate and ondansetron have a safe profile in alcoholic patients; however, none of them has been tested in alcoholic patients with advanced liver disease. To date, baclofen represents the only anti-craving medication formally tested in a randomized clinical trial in alcoholic patients affected by liver cirrhosis, although additional confirmatory studies are warranted.

Alcohol and substance use in liver transplant patients

In this article the epidemiology of substance use and substance disorders in the United States and their association with liver disease are reviewed. The relevance of tobacco use and issues of candidacy as it pertains to substance use are discussed. The use of alcohol while on the waitlist and short sobriety are also addressed. The merits of monitoring of patients are discussed, and the outcomes of these patients after liver transplantation are examined. The article concludes with a summary of recommendations for clinicians working with these patients and possible future directions for both clinical care and research.

Liver transplantation for patients with alcoholic liver disease: an open question

End-stage alcoholic liver disease is a recognised indication for liver transplantation but some questions on the matter remain open. It is difficult to quantify alcohol consumption, and a single definition of post-transplant relapse is lacking. Moreover, there are no internationally accepted criteria for the selection of candidates for liver transplantation and the eligibility parameters for these patients are controversial. Additional clinical and psychological evaluations are necessary in this setting, especially to establish the risk of alcohol relapse. Nevertheless, patient and graft survival rates after liver transplantation in alcoholic liver disease are comparable to those after transplant for other aetiologies, alcohol consumption relapse being one of the most important problems in the post-transplant phase. In conclusion, alcohol-related liver disease is a good indication for liver transplantation. The main future goals are to formulate a well-defined pre-transplant approach and a single definition of alcohol relapse and to improve prevention strategies.

Liver transplantation in patients with alcoholic liver disease

Although alcoholic liver disease (ALD) is one of the most common indications for liver transplantation (LT), there are still unresolved controversies about the goals of treatment, the referral, evaluation, and selection of patients with ALD for LT, and their care after LT. It is uncertain whether there is a large unmet need for LT among patients with ALD because of the unmeasured effects of recent drinking, relapse, and recovery with abstinence in this population. A careful assessment of the extrahepatic effects of alcohol-related end-organ damage is needed for ALD patients who are referred for an LT evaluation. Although there clearly is a relationship between the length of sobriety and future abstinence, the present methods for predicting future drinking are inexact. The survival of ALD patients after LT is as good as the survival of non-ALD patients, although patients with coincident ALD and hepatitis C virus have higher mortality and morbidity rates. After LT, ALD patients have an increased risk of developing malignancies and cardiovascular disease. These risks appear to be linked to cigarette smoking. Covert drinking occurs both before and after transplantation, and approximately 20% of patients return to harmful drinking after LT. Harmful drinking after LT (instead of slips) causes liver damage and reduces survival. Better therapies for controlling addictions to alcohol and nicotine are needed for ALD patients both before and after LT.

A randomized, controlled study of treatment for alcohol dependence in patients awaiting liver transplantation

Alcohol is the second most common cause of cirrhosis necessitating liver transplantation in the United States, yet rates of posttransplant drinking approach 50% and no controlled clinical trials of alcoholism treatment exist in this population. Eligible patients were randomly assigned to receive Motivational Enhancement Therapy (MET), or referral to local treatment sources ("treatment as usual" [TAU]). Addictive behavior, mood states, and general health were compared. Candor concerning alcohol use was encouraged by keeping drinking questionnaires in confidence, except in medical emergencies. Ninety-one subjects were studied; 46 received MET, 45 received TAU, 29 proceeded to transplantation (MET, n = 13; TAU, n = 16). A total of 69 subjects completed 24 weeks of observation, and 25 subjects were assessed at 96 weeks. No difference in study attendance was observed, but significantly more MET subjects attended 1 or more treatment sessions. Twenty-three subjects (25% of sample) drank after randomization but before transplant. Excluding an extreme outlier, MET drinkers had significantly fewer drinks per drinking days than TAU drinkers. Neither treatment plan resulted in significant variances in measures of psychosocial health. In conclusion, although MET afforded no significant benefit over TAU for mood or general health outcomes, this study provides some degree of support for MET to limit the quantity and frequency of pretransplant alcohol consumption among liver transplant candidates with alcohol dependence. However, because of the limited number of study subjects, these data must be interpreted cautiously. Further research to validate our findings or to identify better methods to identify and intervene with patients at risk of pretransplant and posttransplant drinking should continue.

Management of alcoholic liver disease

Understanding alcohol addiction and abstinence is key to treating alcoholic liver disease, since abstinence leads to improvement in all forms of alcoholic liver damage. Although pharmacotherapy for alcoholism, using agents such as naltrexone, acamprosate, topiramate, and baclofen, is an exciting field, few studies have included patients with liver disease or cirrhosis. To treat alcoholic liver injury, corticosteroids have become the standard of care in patients with severe alcoholic hepatitis. In contrast, the role of pharmacotherapy to treat alcoholic fibrosis is unclear, with failure to observe a benefit in randomized, placebo-controlled clinical trials of colchicine, S-adenosylmethionine (SAMe), or phosphatidylcholine. Liver transplantation remains an option in selected patients with life-threatening alcoholic liver disease.

Alcohol consumption by cirrhotic subjects: patterns of use and effects on liver function

OBJECTIVE

We investigated patterns of use of alcohol and its clinical effects among cirrhotic subjects who participated in a randomized clinical trial comparing the efficacy of transjugular intravenous portosystemic shunt and distal splenorenal shunt.

METHODS

There were 132 cirrhotic subjects, 78 with alcoholic liver disease (ALD), who were followed for a median of 49 months (range 2-93 months). Alcohol use was assessed by patient questionnaire, with corroboration by family members.

RESULTS

Twenty-eight subjects (21%) were drinking at study entry and 60 subjects (45%) drank during follow-up. Heavy drinking (>4 drinks/day) was recorded in 25 ALD subjects, but in no non-ALD subjects (P < 0.0001). Drinking by ALD subjects was associated with a 153% increase in gamma-glutamyl transpeptidase (GGT) (P < 0.0001). The frequencies of death (46%vs 30%), ascites (33%vs 20%), encephalopathy (56%vs 42%), and variceal bleeding (11%vs 3%) were greater in the ALD group. In a Cox proportional hazards model only "ever heavy drinking" was associated with death (P= 0.0099), while recent heavy drinking increased the hazard of variceal hemorrhage dramatically (odds ratio 10.85).

CONCLUSIONS

Whereas most cirrhotic subjects, alcoholic or not, did not drink during 5 yr of observation, heavy alcohol use occurred exclusively in ALD patients. Alcohol use by ALD subjects was associated with elevations in GGT and was linked to death and with rebleeding from shunt dysfunction.

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.

Treatment of addictive behaviors in liver transplant patients

Very little addiction treatment research has been done concerning smoking cessation, illicit drugs, or even alcohol abuse in liver transplant patients. Our data suggest that a surprising number of patients who are awaiting a liver transplant for alcohol-related end-stage liver disease will return to drinking before transplantation. We found that motivational enhancement therapy afforded no marked benefit over treatment as usual for drinking, smoking, mood, or general health outcomes in alcoholics awaiting liver transplantation. Stably abstinent methadone-maintained opiate-dependent patients should not be tapered off methadone; are generally good candidates for liver transplant; show low relapse rates into illicit use of opiates; and may be at risk for more medical complications than their counterparts. Pre- and posttransplantation smoking rates are high and cause marked morbidity and mortality. Transplant teams should encourage smoking cessation treatments.Marijuana use in liver transplant recipients is not uncommon, and apart from the risk of developing aspergillosis, additional health risks have not yet been identified.

Liver transplantation for alcoholic liver disease

Alcoholism is a disease of remission and relapse. A lapse in abstinence tends to be viewed as a failure to commit to abstinence, and an acknowledged relapse may lead to the patient's removal from the liver transplant list; however, such a relapse may actually offer insight into alcoholism. Liver transplant physicians should consider recognizing lapses in abstinence as slips that indicate a need for treatment of alcoholism. Further research should address which alcoholic liver patients suffer relapses and how alcohol relapse affects the ability to maintain abstinence before or after transplantation.

[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.

Ein manualisiertes Gruppentherapiekonzept für alkoholabhängige Patienten vor der Lebertransplantation/ Manualised group therapy concept for patients with alcoholic cirrhosis awaiting liver transplantation

OBJECTIVES

Patient compliance after transplantation is of key importance since even moderate deviations from the prescribed therapy regime may cause organ rejection. Patients with alcoholic liver cirrhosis require special therapeutic preparation before the liver transplantation.

METHODS

A manualised group therapy with the aim of maintaining alcohol abstinence, increasing coping skills and therapy adherence is presented and illustrated with a case history. The manual is based on the elements of psychoeducation and problem-solving training. In a second article the results of the clinical evaluation are described.

Xerophthalmia secondary to alcohol-induced malnutrition

BACKGROUND

Xerophthalmia refers to the ocular manifestations associated with vitamin A deficiency. Vitamin A deficiency can be caused by numerous disorders, including alcohol-induced malnutrition. The ocular manifestations of xerophthalmia include conjunctival and corneal xerosis (drying), keratomalacia (corneal necrosis/ulceration), nyctalopia (night blindness), and Bitot's spots (conjunctival lesions).

CASE REPORT

A 47-year-old white male with complaints of dryness and difficulty seeing at night presented to our clinic for consultation from general medicine to rule out xerophthalmia. Laboratory testing and general medicine, psychiatry, and nutrition evaluations confirmed the systemic diagnosis of alcohol-induced malnutrition. He admits that his alcoholism was induced by depression. Confirmed associated disorders compounding the malnutrition include alcoholic cirrhosis, protein deficiency, and megaloblastic anemia. The patient had xerophthalmia diagnosed in the optometry clinic as a result of symptoms, slit lamp examination signs, and the associated disorders. The associated disorders were treated with systemic medications and vitamins. Ophthalmic treatment consisted of carboxymethylcellulose-based artificial tears.

CONCLUSIONS

Although xerophthalmia and vitamin A deficiency are more common in underdeveloped countries, their presentation in the United States may be induced by conditions such as liver cirrhosis, malnutrition, and alcoholism. This report summarizes ocular manifestations of alcoholism and presents a case of xerophthalmia secondary to alcohol-induced malnutrition and the role of optometry in its treatment and management.

Liver transplantation in alcoholic patients

Alcoholic liver disease is one of the most common causes of cirrhosis and indications for orthotopic liver transplantation in Europe and North America. The reluctance to transplant alcoholics stems in part from the view that alcoholics bear responsibility for their illness. There is also the perception that the alcoholic person is likely to relapse into alcohol use after transplantation and thereby damage the allograft. In this review, we considered the evaluation for and outcome of liver transplantation in alcoholics with special attention to the specific risks of alcohol relapse, to show that alcoholism should be considered like other co-morbid states rather than as a moral flaw.

Psychosocial profiling: a holistic management tool for non-compliance*

We introduce a new concept of psychosocial profiling as a tool that provides the transplant team with a psychosocial framework for identification, intervention and management of non-compliance. This will also increase our understanding of emotional problems experienced by patients before transplant, as a result of living with the uncertainty and medical side effects of chronic illness. Psychosocial profiling is adaptable throughout the transplant process and gives every patient an opportunity of psychosocial support to help him or her into a position of emotional stability and compliance with their medications and postoperative care. Implementation of this strategy will move health care professionals from being gatekeepers to managers and facilitators of holistic care in recipients of transplants.

Pretransplant psychiatric and medical comorbidity of alcoholic liver disease patients who received liver transplant

The authors examined the pretransplant prevalence of comorbid physical and psychological disorders in 112 alcoholic liver disease patients who received liver transplant. Fifty-six percent of the patients had comorbid hepatitis C or hepatitis B virus, 40% had used other substances in addition to alcohol, 25% met the criteria for a lifetime DSM-IV nonalcohol substance use disorder, 36% for a lifetime depressive disorder, and 12% for a lifetime anxiety disorder. The findings suggest the need for pretransplant psychiatric evaluation of alcoholic liver disease patients to identify nonalcohol substance use disorders and other psychiatric disorders that may require treatment.

Liver Disease in Heavy Drinkers With and Without Alcohol Withdrawal Syndrome

BACKGROUND

Withdrawal syndrome is a hallmark of alcohol dependence. The characteristics of alcohol consumption, closely related to dependence, could influence the development of alcoholic liver disease. The study aimed to investigate if patients with severe alcohol withdrawal syndrome have a peculiar profile of liver disease.

METHODS

The study included 256 heavy drinkers (aged 19-75 years, 70.3% males) admitted to an Internal Medicine Department. Patients admitted for complications of liver disease were not included. Severe alcohol withdrawal syndrome (seizures, disordered perceptions, or delirium) developed in 150 patients (58.6%). Alcohol consumption (daily quantity, duration, and pattern [regular or irregular]) was assessed by questionnaire. Liver biopsy was performed in all cases.

RESULTS

Patients with alcohol withdrawal syndrome showed a lower prevalence of liver cirrhosis and a higher prevalence of alcoholic hepatitis than patients without it. The negative association of alcohol withdrawal syndrome with liver cirrhosis persisted after we adjusted for sex, daily intake, duration, and pattern of alcohol consumption. Alcoholic hepatitis was independently associated with the irregular pattern of alcohol consumption, which was closely associated with severe alcohol withdrawal syndrome.

CONCLUSIONS

The profile of liver injury is different in heavy drinkers who develop and who do not develop a severe alcohol withdrawal syndrome when admitted to the hospital.

A prospective analysis of oxidative stress and liver transplantation

BACKGROUND

Oxidative stress (OS) is a potential mechanism of injury in many deleterious complications of orthotopic liver transplantation (OLT). Therefore, we evaluated OS prospectively in a cohort of 50 adult patients before, during, and after OLT.

METHODS

Urine, collected preoperatively, perioperatively, and at intervals for the first postoperative year, was analyzed for dinor-dihydro-isoprostane F2alpha-III (dinor-dihydro iPF2alpha-III), a well-characterized in vivo indicator of OS. Clinical events were extracted from the clinical records.

RESULTS

One-year patient and graft survival were 86% and 80%, respectively. There were nine episodes of acute cellular rejection (ACR). Twenty patients each experienced at least one adverse event. Pretransplantation urinary dinor-dihydro iPF2alpha-III levels were elevated, compared to healthy volunteers, and rose significantly following reperfusion of the grafted liver. Levels fell sharply following OLT but never reached those of control subjects. Urinary dinor-dihydro iPF2alpha-III levels steadily increased thereafter, reaching preoperative levels within 12 months of transplantation. There was no significant difference in dinor-dihydro iPF2alpha-III excretion, with respect to hepatitis C virus (HCV) status, the development of ACR, or the presence or absence of a composite of predesignated adverse events.

CONCLUSIONS

OLT recipients exhibit enhanced lipid peroxidation in vivo, which is augmented during intra-operative liver reperfusion. Although OS declines following OLT, it redevelops gradually, albeit without association with clinical events such as acute cellular rejection, organ failure, or infection of the allograft by HCV. We conclude that OS increases in the first year after liver transplantation, in a time-dependent fashion, but independent of clinical events affecting the allograft.

Alcoholism treatment after liver transplantation: lessons learned from a clinical trial that failed

Alcoholic liver disease is the second most common indication for liver transplantation in the United States. The lack of alcoholism treatment studies led us to study motivational enhancement therapy (MET) plus naltrexone after transplant. The authors could not complete this study. Sixty alcoholic patients were to receive MET plus naltrexone or placebo for 6 months. Fifty men and 5 women were screened. Nine died and 15 were not approached. Of 31 approached, 20 were ineligible, 11 refused, and 5 entered but dropped out before completion. Barriers to posttransplant alcoholism included infirmity, intensive medical management, and denial for alcoholism treatment. Because 30%-50% of alcoholic patients drink after transplant, the authors suggest using MET alone pretransplant.
