Liver transplantation in alcoholic patients: impact of an alcohol addiction unit within a liver transplant center.

ABSTRACT: BACKGROUND:Many concerns about liver transplantation in alcoholic patients are related to the risk of alcohol recidivism. Starting from 2002, an Alcohol Addiction Unit (AAU) was formed within the liver transplant center for the management of alcoholic patients affected by end-stage liver disease and included in the waiting list for transplantation. We evaluated retrospectively the impact of the AAU on alcohol recidivism after transplantation. The relationship between alcohol recidivism and the duration of alcohol abstinence before transplant was evaluated as well. METHODS:Between 1995 and 2010, 92 cirrhotic alcoholic patients underwent liver transplantation. Clinical evaluation and management of alcohol use in these patients was provided by psychiatrists with expertise in addiction medicine not affiliated to the liver transplant center before 2002 (n = 37; group A), or by the clinical staff of the AAU within the liver transplant center starting from 2002 (n = 55; group B). RESULTS:Group B, as compared with group A, showed a significantly lower prevalence of alcohol recidivism (16.4 vs. 35.1%; p = 0.038) and a significantly lower mortality (14.5 vs. 37.8%; p = 0.01). Furthermore, an analysis of group B patients with either ?6 or <6 months of alcohol abstinence before transplantation showed no difference in the rate of alcohol recidivism (21.1 vs. 15.4%; p = ns). CONCLUSIONS:The presence of an AAU within a liver transplant center reduces the risk of alcohol recidivism after transplantation. A pretransplant abstinence period <6 months might be considered, at least in selected patients managed by an AAU.

Project description:Background & aimsLittle is known about outcomes of liver transplantation for patients with non-alcoholic steatohepatitis (NASH). We aimed to determine the frequency and outcomes of liver transplantation for patients with NASH in Europe and identify prognostic factors.MethodsWe analysed data from patients transplanted for end-stage liver disease between January 2002 and December 2016 using the European Liver Transplant Registry database. We compared data between patients with NASH versus other aetiologies. The principle endpoints were patient and overall allograft survival.ResultsAmong 68,950 adults undergoing first liver transplantation, 4.0% were transplanted for NASH - an increase from 1.2% in 2002 to 8.4% in 2016. A greater proportion of patients transplanted for NASH (39.1%) had hepatocellular carcinoma (HCC) than non-NASH patients (28.9%, p <0.001). NASH was not significantly associated with survival of patients (hazard ratio [HR] 1.02, p = 0.713) or grafts (HR 0.99; p = 0.815) after accounting for available recipient and donor variables. Infection (24.0%) and cardio/cerebrovascular complications (5.3%) were the commonest causes of death in patients with NASH without HCC. Increasing recipient age (61-65 years: HR 2.07, p <0.001; >65: HR 1.72, p = 0.017), elevated model for end-stage liver disease score (>23: HR 1.48, p = 0.048) and low (<18.5 kg/m2: HR 4.29, p = 0.048) or high (>40 kg/m2: HR 1.96, p = 0.012) recipient body mass index independently predicted death in patients transplanted for NASH without HCC. Data must be interpreted in the context of absent recognised confounders, such as pre-morbid metabolic risk factors.ConclusionsThe number and proportion of liver transplants performed for NASH in Europe has increased from 2002 through 2016. HCC was more common in patients transplanted with NASH. Survival of patients and grafts in patients with NASH is comparable to that of other disease indications.Lay summaryThe prevalence of non-alcoholic fatty liver disease has increased dramatically in parallel with the worldwide increase in obesity and diabetes. Its progressive form, non-alcoholic steatohepatitis, is a growing indication for liver transplantation in Europe, with good overall outcomes reported. However, careful risk factor assessment is required to maintain favourable post-transplant outcomes in patients with non-alcoholic steatohepatitis.

Project description:Early liver transplant (LT) for alcohol-associated disease (i.e., without a specific sobriety period) is controversial but increasingly used. Using the multicenter American Consortium of Early Liver Transplantation for Alcoholic Hepatitis (ACCELERATE-AH) cohort, we aimed to develop a predictive tool to identify patients pretransplant with low risk for sustained alcohol use posttransplant to inform selection of candidates for early LT. We included consecutive ACCELERATE-AH LT recipients between 2012 and 2017. All had clinically diagnosed severe alcoholic hepatitis (AH), no prior diagnosis of liver disease or AH, and underwent LT without a specific sobriety period. Logistic and Cox regression, classification and regression trees (CARTs), and least absolute shrinkage and selection operator (LASSO) regression were used to identify variables associated with sustained alcohol use post-LT. Among 134 LT recipients for AH with median period of alcohol abstinence pre-LT of 54 days, 74% were abstinent, 16% had slips only, and 10% had sustained alcohol use after a median 1.6 (interquartile range [IQR]: 0.7-2.8) years follow-up post-LT. Four variables were associated with sustained use of alcohol post-LT, forming the Sustained Alcohol Use Post-LT (SALT) score (range: 0-11): >10 drinks per day at initial hospitalization (+4 points), multiple prior rehabilitation attempts (+4 points), prior alcohol-related legal issues (+2 points), and prior illicit substance abuse (+1 point). The C statistic was 0.76 (95% confidence interval [CI]: 0.68-0.83). A SALT score ?5 had a 25% positive predictive value (95% CI: 10%-47%) and a SALT score of <5 had a 95% negative predictive value (95% CI: 89%-98%) for sustained alcohol use post-LT. In internal cross-validation, the average C statistic was 0.74. Conclusion: A prognostic score, the SALT score, using four objective pretransplant variables identifies candidates with AH for early LT who are at low risk for sustained alcohol use posttransplant. This tool may assist in the selection of patients with AH for early LT or in guiding risk-based interventions post-LT.

Project description:Accidental or suicidal poisoning with yellow phosphorus or metal phosphides (YPMP) such as aluminum (AlP) zinc phosphide (Zn3P2) commonly cause acute liver failure (ALF) and cardiotoxicity. These are used as household, agricultural and industrial rodenticides and in production of ammunitions, firecrackers and fertilizers. In absence of a clinically available laboratory test for diagnosis or toxin measurement or an antidote, managing their poisoning is challenging even at a tertiary care center with a dedicated liver intensive care unit (LICU) and liver transplant facility. Patients with YPMP related ALF were monitored using standardized clinical, hemodynamic, biochemical, metabolic, neurological, electrocardiography (ECG) and SOFA score and managed using uniform intensive care, treatment and transplant protocols in LICU. Socio-demographic characteristics, clinical and biochemical parameters and scores were summarized and compared between 3 groups i.e. spontaneous survivors, transplanted patients and non-survivors. Predictors of spontaneous survival and the need for liver transplant are also evaluated. Nineteen patients with YPMP related ALF were about 32 years old (63.2% females) and presented to us at a median of 3 (0 - 10) days after poisoning. YPMP related cardiotoxicity was rapidly progressive and fatal whereas liver transplant was therapeutic for ALF. Spontaneous survivors had lower dose ingestion (<17.5 grams), absence of cardiotoxicity, < grade 3 HE, lactate < 5.8, SOFA score < 14.5, and increase in SOFA score by < 5.5. Patients with renal failure need for CVVHDF and KCC positivity on account of PT-INR > 6.5 had higher mortality risk. Patients undergoing liver transplant and with spontaneous recovery required longer ICU and hospital stay. At median follow-up of 3.4 (2.6 - 5.5) years, all spontaneous survivors and transplanted patients are well with normal liver function. Early transfer to a specialized center, pre-emptive close monitoring, and intensive care and organ support with ventilation, CVVHDF, plasmapheresis and others may maximize their chances of spontaneous recovery, allow accurate prognostication and a timely liver transplant.
