The coronavirus disease-2019 (COVID-19) pandemic has had a large impact on patients with chronic liver disease (CLD) and liver transplantation (LT) recipients. Patients with advanced CLD are at a significantly increased risk of poor outcomes in the setting of severe acute respiratory syndrome coronavirus 2 infection. The pandemic has also considerably altered the management and care that is provided to patients with CLD, pre-LT patients, and LT recipients. Vaccination against COVID-19 protects patients with CLD and LT recipients from adverse outcomes and is safe in these patients; however, vaccine efficacy may be reduced in LT recipients and other immunosuppressed patients.

Early liver transplantation (LT) for alcohol-associated hepatitis (AH) is the fastest growing indication for LT, but prediction of harmful alcohol use post-LT remains limited. Among 10 ACCELERATE-AH centers, we examined psychosocial evaluations from consecutive LT recipients for AH from 2006 to 2017. A multidisciplinary panel used content analysis to develop a maximal list of psychosocial variables. We developed an artificial intelligence model to predict post-LT harmful alcohol use. The cohort included training (N = 91 among 8 centers) and external validation (N = 25 among 2 centers) sets, with median follow-up of 4.4 (IQR 3.0-6.0) years post-LT. In the training set, AUC was 0.930 (95%CI 0.862-0.998) with positive predictive value of 0.891 (95%CI 0.620-1.000), internally validated through fivefold cross-validation. In the external validation set, AUC was 0.692 (95%CI 0.666-0.718) with positive predictive value of 0.82 (95%CI 0.625-1.000). The model identified specific variables related to social support and substance use as highly important to predict post-LT harmful alcohol use. We retrospectively developed and validated a model that identified psychosocial profiles at LT predicting harmful alcohol use post-LT for AH. This preliminary model may inform selection and post-LT management for AH and warrants prospective evaluation in larger studies among all alcohol-associated liver disease being considered for early LT.

Despite the likely benefits of palliative care (PC) for patients with cirrhosis, physician experiences and perspectives about best practices are variable. We aimed to assess PC experience and gaps in training among transplant hepatology fellows. We conducted a national survey of all transplant hepatology fellows enrolled in accredited fellowship programs during the 2020-2021 academic year. We assessed the frequency of PC provision and comfort with physical and psychological symptom management, psychosocial care, communication skills, advance care planning, and end-of-life care. A total of 45 of 56 (79%) of transplant hepatology fellows responded to the survey; 50% (n=22) were female. Most trained at centers performing over 100 transplants per year (67%, n=29) distributed evenly across geographic regions. Most fellows (69%, n=31) had a PC or hospice care rotation during residency, and 42% (n=19) of fellows received education in PC during transplant hepatology fellowship. Fellows reported feeling moderately to very comfortable with communication skills such as breaking bad news (93%, n=41) and leading family meetings (75%, n=33), but nearly one-third (30%, n=13) reported feeling not very or not at all comfortable assessing and managing anxiety and depression (30%, n=13) and spiritual distress (34%, n=15). Nearly one-quarter (22%, n=10) had never discussed or documented advance care plans during fellowship. Fellows wished to receive future instruction on the assessment and management of physical symptoms (68%, n=30) and anxiety and depression (64%, n=28). Conclusion: Our survey highlights gaps in PC experience and education during transplant hepatology fellowship, lack of comfort in managing psychological distress and advance care planning, and desire to improve skills, particularly in symptom management. Future studies should investigate how to enhance transplant hepatology competencies in these PC domains and whether this impacts clinical care, advance care planning, or patient experience.

Alcohol-associated liver disease (ALD) can be coded in United Network for Organ Sharing (UNOS) as either alcoholic cirrhosis or alcoholic hepatitis (AH), without having specific criteria to assign either diagnosis. In this multicenter American Consortium of Early Liver Transplantation for Alcoholic Hepatitis (ACCELERATE-AH) study, we sought to assess the concordance of the clinician diagnosis of AH at liver transplantation (LT) listing versus UNOS data entry of AH as listing diagnosis. In a prior study, consecutive early LT recipients transplanted for AH between 2012 and 2017 were identified by chart review at 10 ACCELERATE-AH sites. In this current study, these same LT recipients were identified in the UNOS database. The primary UNOS diagnostic code was evaluated for concordance with the chart-review assignment of AH. In cases where the primary listing diagnosis in UNOS was not AH, we determined the reason for alternate classification. Among 124 ACCELERATE-AH LT recipients with a chart-review diagnosis of AH, only 43/124 (35%) had AH as listing diagnosis in UNOS; 80 (64%) were listed as alcoholic cirrhosis, and 1 (1%) as fulminant hepatic necrosis. Of the 81 patients missing AH as a UNOS listing diagnosis code, the reasons for alternate classification were 44 (54%) due to a lack of awareness of a separate diagnosis code for AH; 13 (16%) due to concomitant clinical diagnosis of AH and alcoholic cirrhosis in the chart; 12 (15%) due to clinical uncertainty regarding the diagnosis of AH versus acute decompensated alcoholic cirrhosis; and 12 (15%) due to a data entry error. In conclusion, in a large cohort of LT recipients with AH, only 35% were documented as such in UNOS. Increased education and awareness for those performing UNOS data entry, the establishment of specific criteria to define AH in the UNOS database, and the ability to document dates of alcohol use would allow future research on ALD to be more informative.

Introduction and aim: Real-world epidemiologic data to guide hepatitis C virus (HCV)-related public health initiatives are lacking. The aim of this study was to describe the prevalence and epidemiological characteristics of a large cohort of patients with an HCV diagnosis evaluated in one of the largest health systems in the United States. Materials and methods: De-identified demographic and clinical data were extracted from the electronic health record for patients actively followed within the Providence Health & Services health care system. Rates of HCV prevalence and co-morbid illnesses among HCV-infected patients were determined. Results: Among 2,735,511 active patients, 23,492 (0.86%) were found to have evidence of HCV infection, the majority of which were Caucasian (78.2%) and born between the years 1945 and 1965 (68.3%). In comparison to Caucasians, higher rates of HCV infection were found among Native Americans (2.5% vs. 0.95%, p

The severe acute respiratory syndrome coronavirus 2 pandemic has drastically altered all facets of clinical care and research. Clinical research in hepatology has had a rich tradition in several domains, including the discovery and therapeutic development for diseases such as hepatitis B and C and studying the natural history of many forms of chronic liver disease. National Institutes of Health, foundation, and industry funding have provided important opportunities to advance the academic careers of young investigators while they strived to make contributions to the field. Instantaneously, however, all nonessential research activities were halted when the pandemic started, forcing those involved in clinical research to rethink their research strategy, including a shift to coronavirus disease 2019 research while endeavoring to maintain their preexisting agenda. Strategies to maintain the integrity of ongoing studies, including patient follow-up, safety assessments, and continuation of investigational products, have included a shift to telemedicine, remote safety laboratory monitoring, and shipping of investigational products to study subjects. As a revamp of research is being planned, unique issues that face the research community include maintenance of infrastructure, funding, completion of studies in the predetermined time frame, and the need to reprogram career path timelines. Real-world databases, biomarker and long-term follow up studies, and research involving special groups (children, the homeless, and other marginalized populations) are likely to face unique challenges. The implementation of telemedicine has been dramatically accelerated and will serve as a backbone for the future of clinical research. As we move forward, innovation in clinical trial design will be essential for conducting optimized clinical research.

Background & Aims Early liver transplantation (LT) for alcoholic hepatitis (AH) is lifesaving but concerns regarding return to harmful alcohol use remain. We sought to identify distinct patterns of alcohol use post-LT to inform pre-LT candidate selection and post-LT addiction care. Methods Detailed post-LT alcohol use data was gathered retrospectively from consecutive patients with severe AH at 11 ACCELERATE-AH sites from 2006–2018. Latent class analysis identified longitudinal patterns of alcohol use post-LT. Logistic and Cox regression evaluated associations between patterns of alcohol use with pre-LT variables and post-LT survival. A microsimulation model estimated the effect of selection criteria on overall outcomes. Results Of 153 LT recipients, 1-, 3-, and 5-year survival were 95%, 88% and 82%. Of 146 LT recipients surviving to home discharge, 4 distinct longitudinal patterns of post-LT alcohol use were identified: Pattern 1 [abstinent](n = 103; 71%), pattern 2 [late/non-heavy](n = 9; 6.2%), pattern 3 [early/non-heavy](n = 22; 15%), pattern 4 [early/heavy](n = 12; 8.2%). One-year survival was similar among the 4 patterns (100%), but patients with early post-LT alcohol use had lower 5-year survival (62% and 53%) compared to abstinent and late/non-heavy patterns (95% and 100%). Early alcohol use patterns were associated with younger age, multiple prior rehabilitation attempts, and overt encephalopathy. In simulation models, the pattern of post-LT alcohol use changed the average life-expectancy after early LT for AH. Conclusions A significant majority of LT recipients for AH maintain longer-term abstinence, but there are distinct patterns of alcohol use associated with higher risk of 3- and 5-year mortality. Pre-LT characteristics are associated with post-LT alcohol use patterns and may inform candidate selection and post-LT addiction care.

Background and aims Coronavirus disease 2019 (COVID-19), the illness caused by the SARS-CoV-2 virus, is rapidly spreading throughout the world. Hospitals and healthcare providers are preparing for the anticipated surge in critically ill patients, but few are wholly equipped to manage this new disease. The goals of this document are to provide data on what is currently known about COVID-19, and how it may impact hepatologists and liver transplant providers and their patients. Our aim is to provide a template for the development of clinical recommendations and policies to mitigate the impact of the COVID-19 pandemic on liver patients and healthcare providers. Approach and results This article discusses what is known about COVID-19 with a focus on its impact on hepatologists, liver transplant providers, patients with liver disease, and liver transplant recipients. We provide clinicians with guidance for how to minimize the impact of the COVID-19 pandemic on their patients' care. Conclusions The situation is evolving rapidly, and these recommendations will need to evolve as well. As we learn more about how the COVID-19 pandemic impacts the care of patients with liver disease, we will update the online document available at https://www.aasld.org/about-aasld/covid-19-and-liver.

Background and aims Liver disease is prevalent in the United States, and as the population ages, an increasing number of patients are anticipated to present for care. The state of the current hepatology workforce and future demand for hepatology providers is not known. The aim of this study was to model future projections for hepatology workforce demand. Approach and results A workforce study of hepatology providers in the United States was completed using primary and secondary data sources. An integrated workforce framework model was used that combined socioeconomic factors that drive economic demand, epidemiological factors that drive need, and utilization rates of health care services. Supply and demand projections were calculated for adult and pediatric hepatology professionals. Sensitivity analyses were conducted to cover the feasible range of these assumptions. An electronic survey of American Association for the Study of Liver Diseases (AASLD) members whose practice included 50% or more hepatology was conducted. In 2018, the adult and pediatric workforce included 7,296 and 824 hepatology providers, respectively, composed of hepatologists, gastroenterologists, and advanced practice providers whose practice was ≥50% hepatology. The modeling analysis projects that in 2023, 2028, and 2033, there will be shortages of 10%, 23%, and 35% adult hepatology providers, respectively, and 19%, 20%, and 16% pediatric hepatology providers, respectively. In sensitivity analyses, a shortage of hepatology providers is predicted even under optimistic assumptions. Among the respondents to the survey, the median age was higher among gastroenterologists and general hepatologists compared with transplant hepatologists. The most common category treated by transplant hepatologists was general hepatology. Conclusions There is an impending critical shortage of adult and pediatric hepatology providers. Strategies are needed to encourage clinicians to pursue hepatology, especially in areas outside of transplant centers.

Background & Aims Direct-acting antivirals (DAAs) are effective against hepatitis C virus and sustained virologic response is associated with reduced incidence of hepatocellular carcinoma (HCC). However, there is controversy over the use of DAAs in patients with active or treated HCC and uncertainty about optimal management of these patients. We aimed to characterize attitudes and practice patterns of hepatology practitioners in the United States regarding the use of DAAs in patients with HCC. Methods We conducted a survey of hepatology providers at 47 tertiary care centers in 25 states. Surveys were sent to 476 providers and we received 279 responses (58.6%). Results Provider beliefs about risk of HCC recurrence after DAA therapy varied: 48% responded that DAAs reduce risk, 36% responded that DAAs do not change risk, and 16% responded that DAAs increase risk of HCC recurrence. However, most providers believed DAAs to be beneficial to and reduce mortality of patients with complete response to HCC treatment. Accordingly, nearly all providers (94.9%) reported recommending DAA therapy to patients with early-stage HCC who received curative treatment. However, fewer providers recommended DAA therapy for patients with intermediate (72.9%) or advanced (57.5%) HCC undergoing palliative therapies. Timing of DAA initiation varied among providers based on HCC treatment modality: 49.1% of providers reported they would initiate DAA therapy within 3 months of surgical resection whereas 45.9% and 5.0% would delay DAA initiation for 3–12 months and >1 year post-surgery, respectively. For patients undergoing transarterial chemoembolization (TACE), 42.0% of providers would provide DAAs within 3 months of the procedure, 46.7% would delay DAAs until 3–12 months afterward, and 11.3% would delay DAAs more than 1 year after TACE. Conclusions Based on a survey sent to hepatology providers, there is variation in provider attitudes and practice patterns regarding use and timing of DAAs for patients with HCC. Further studies are needed to characterize the risks and benefits of DAA therapy in this patient population.

Background & aimsEarly liver transplantation (without requiring a minimum period of sobriety) for severe alcohol-associated hepatitis (AH) is controversial: many centers delay eligibility until a specific period of sobriety (such as 6 months) has been achieved. To inform ongoing debate and policy, we modeled long-term outcomes of early vs delayed liver transplantation for patients with AH.MethodsWe developed a mathematical model to simulate early vs delayed liver transplantation for patients with severe AH and different amounts of alcohol use after transplantation: abstinence, slip (alcohol use followed by sobriety), or sustained use. Mortality of patients before transplantation was determined by joint-effect model (based on Model for End-Stage Liver Disease [MELD] and Lille scores). We estimated life expectancies of patients receiving early vs delayed transplantation (6-month wait before placement on the waitlist) and life years lost attributable to alcohol use after receiving the liver transplant.ResultsPatients offered early liver transplantation were estimated to have an average life expectancy of 6.55 life years, compared with an average life expectancy of 1.46 life years for patients offered delayed liver transplantation (4.49-fold increase). The net increase in life expectancy from offering early transplantation was highest for patients with Lille scores of 0.50-0.82 and MELD scores of 32 or more. Patients who were offered early transplantation and had no alcohol use afterward were predicted to survive 10.85 years compared with 3.62 years for patients with sustained alcohol use after transplantation (7.23life years lost). Compared with delayed transplantation, early liver transplantation increased survival times in all simulated scenarios and combinations of Lille and MELD scores.ConclusionsIn a modeling study of assumed carefullyselected patients with AH, early vs delayed liver transplantation (6months of abstinence from alcohol before transplantation) increased survival times of patients, regardless of estimated risk of sustained alcohol use after transplantation. These findings support early liver transplantation for patients with severe AH. The net increasein life expectancy was maintained in all simulated extreme scenarios but should be confirmed in prospective studies. Sustained alcohol use after transplantation significantly reduced but did not eliminate thebenefits of early transplantation. Strategies are needed toprevent and treat posttransplantation use of alcohol.

Risk of recurrent hepatocellular carcinoma (rHCC) after liver transplantation (LT) depends on the pre-LT HCC burden, tumor behavior, and response to locoregional therapy (LRT). In December 2017, LT priority for HCC was expanded to select patients outside the Milan criteria who respond to LRT. Our aims were to develop a novel objective measure of pre-LT HCC burden (model of recurrent hepatocellular carcinoma-initial, maximum, last [RH-IML]), incorporating tumor behavior over time, and to apply RH-IML to model post-LT rHCC. Using United Network for Organ Sharing data from between 2002-2014 (development) and 2015-2017 (validation), we identified adult LT recipients with HCC and assessed pre-LT HCC tumor behavior and post-LT rHCC. For each patient, HCC burden was measured at 3 points on the waiting list: initial (I), maximum (M) total tumor diameter, and last (L) exception petition. HCC burden at these 3 points were classified as (A) Milan, (B) Milan, (C)Milan to University of California, San Francisco (UCSF), and (D)UCSF, resulting in each patient having a 3-letter RH-IML designation. Of 16,558 recipients with HCC, 1233 (7%) had any post-LT rHCC. rHCC rates were highest in RH-IML group CCC (15%) and DDD (18%). When M and L tumor burdens did not exceed Milan (class B or A), rHCC was low (≤10%) as in AAA, ABA, ABB, BBA, BBB; rHCC was also low (≤10%) with successful downstaging when L was A (Milan) and M tumor burden did not exceed I, as in BBA, CCA, and DDA. In conclusion, the RH-IML classification system is a simple summative measure of HCC burden that incorporates tumor behavior over time. RH-IML also estimates post-LT rHCC risk and is a useful tool for evaluating risk for rHCC post-LT.

Background & aimsThe American Consortium of Early Liver Transplantation for Alcoholic Hepatitis comprises 12 centers from 8 United Network for Organ Sharing regions studying early liver transplantation (LT) (without mandated period of sobriety) for patients with severe alcoholic hepatitis (AH). We analyzed the outcomes of these patients.MethodsWe performed a retrospective study of consecutive patients with a diagnosis of severe AH and no prior diagnosis of liver disease or episodes of AH, who underwent LT before 6 months of abstinence from 2006 through 2017 at 12 centers. We collected data on baseline characteristics, psychosocial profiles, level of alcohol consumption before LT, disease course and treatment, and outcomes of LT. The interval of alcohol abstinence was defined as the time between last drink and the date of LT. The primary outcomes were survival and alcohol use after LT, defined as slip or sustained.ResultsAmong 147 patients with AH who received liver transplants, the median duration of abstinence before LT was 55 days; 54% received corticosteroids for AH and the patients had a median Lille score of 0.82 and a median Sodium Model for End-Stage Liver Disease score of 39. Cumulative patient survival percentages after LT were 94% at 1 year (95% confidence interval [CI], 89%-97%) and 84% at 3 years (95% CI, 75%-90%). Following hospital discharge after LT, 72% were abstinent, 18% had slips, and 11% had sustained alcohol use. The cumulative incidence of any alcohol use was 25% at 1 year (95% CI, 18%-34%) and 34% at 3 years (95% CI, 25%-44%) after LT. The cumulative incidence of sustained alcohol use was 10% at 1 year (95% CI, 6%-18%) and 17% at 3 years (95% CI, 10%-27%) after LT. In multivariable analysis, only younger age was associated with alcohol following LT (P= .01). Sustained alcohol use after LT was associated with increased risk of death (hazard ratio, 4.59; P= .01).ConclusionsIn a retrospective analysis of 147 patients who underwent early LT (before 6 months of abstinence) for severe AH, we found that most patients survive for 1year (94%) and 3 years (84%), similar to patients receiving livertransplants for other indications. Sustained alcohol use after LT was infrequent but associated with increased mortality. Our findings support the selective use of LT as a treatment for severe AH. Prospective studies are needed to optimize selection criteria, management of patients after LT, and long-term outcomes.

Immunotactoid deposits are defined by their ultrastructural appearance and are characterized by microtubular or cylindrical structures typically measuring greater than 30 nm in diameter. Although a rare entity, immunotactoid deposition most often manifests as immunotactoid glomerulopathy and is associated with underlying lymphoplasmacytic disorders. Corneal immunotactoid deposition known as immunotactoid keratopathy has also been reported in patients with paraproteinemia. Here, we describe the first reported case of immunotactoid deposition in the stomach. The deposits were composed solely of kappa immunoglobulin light chains without significant lambda light chain or immunoglobulin heavy chain components. The patient displayed no renal signs or symptoms, and additional thorough clinical examination failed to detect any evidence of a paraproteinemia or plasma cell dyscrasia. Thus, the gastric immunotactoid deposits in this case appear to be an isolated finding of light chain deposition, of which the significance and etiology are unclear.

To determine if intracranial pressure monitor placement in patients with acute liver failure is associated with significant clinical outcomes.Retrospective multicenter cohort study.Academic liver transplant centers comprising the U.S. Acute Liver Failure Study Group.Adult critically ill patients with acute liver failure presenting with grade III/IV hepatic encephalopathy (n = 629) prospectively enrolled between March 2004 and August 2011.Intracranial pressure monitored (n = 140) versus nonmonitored controls (n = 489).Intracranial pressure monitored patients were younger than controls (35 vs 43 yr, p0.001) and more likely to be on renal replacement therapy (52% vs 38%, p = 0.003). Of 87 intracranial pressure monitored patients with detailed information, 44 (51%) had evidence of intracranial hypertension (intracranial pressure25 mm Hg) and overall 21-day mortality was higher in patients with intracranial hypertension (43% vs 23%, p = 0.05). During the first 7 days, intracranial pressure monitored patients received more intracranial hypertension-directed therapies (mannitol, 56% vs 21%; hypertonic saline, 14% vs 7%; hypothermia, 24% vs 10%; p0.03 for each). Forty-one percent of intracranial pressure monitored patients received liver transplant (vs 18% controls; p0.001). Overall 21-day mortality was similar (intracranial pressure monitored 33% vs controls 38%, p = 0.24). Where data were available, hemorrhagic complications were rare in intracranial pressure monitored patients (4 of 56 [7%]; three died). When stratifying by acetaminophen status and adjusting for confounders, intracranial pressure monitor placement did not impact 21-day mortality in acetaminophen patients (p = 0.89). However, intracranial pressure monitor was associated with increased 21-day mortality in nonacetaminophen patients (odds ratio, ~ 3.04; p = 0.014).In intracranial pressure monitored patients with acute liver failure, intracranial hypertension is commonly observed. The use of intracranial pressure monitor in acetaminophen acute liver failure did not confer a significant 21-day mortality benefit, whereas in nonacetaminophen acute liver failure, it may be associated with worse outcomes. Hemorrhagic complications from intracranial pressure monitor placement were uncommon and cannot account for mortality trends. Although our results cannot conclusively confirm or refute the utility of intracranial pressure monitoring in patients with acute liver failure, patient selection and ancillary assessments of cerebral blood flow likely have a significant role. Prospective studies would be required to conclusively account for confounding by illness severity and transplant.

Objective We describe a young woman with previously undiagnosed thyrotoxicosis who presented with acute liver failure (ALF). Methods We present a case report and review the relevant literature. Results An extensive evaluation excluded possible causes of ALF other than thyrotoxicosis. The management of thyrotoxicosis posed several unique challenges in the setting of ALF, particularly because we did not want to use potentially hepatotoxic thionamides. The patient was treated with prednisone and propranolol and was started on potassium iodide when she was listed for liver transplantation. She underwent an uncomplicated liver transplant and subsequent thyroidectomy and is doing well. Conclusion This well-characterized case describes thyrotoxicosis as a possible cause of ALF after thoroughly excluding other possible causes and illustrates the challenges of simultaneously managing both disorders. To our knowledge, this is the first report of ALF possibly resulting from untreated thyrotoxicosis that was successfully treated with liver transplantation. (Endocr Pract. 2013;19:e57-e60)

Acute liver failure (ALF) is classically defined by coagulopathy and hepatic encephalopathy (HE); however, acute liver injury (ALI), i.e., severe acute hepatocyte necrosis without HE, has not been carefully defined nor studied. Our aim is to describe the clinical course of specifically defined ALI, including the risk and clinical predictors of poor outcomes, namely progression to ALF, the need for liver transplantation (LT) and death.386 subjects prospectively enrolled in the Acute Liver Failure Study Group registry between 1 September 2008 through 25 October 2013, met criteria for ALI: International Normalized Ratio (INR)≥2.0 and alanine aminotransferase (ALT)≥10 × elevated (irrespective of bilirubin level) for acetaminophen (N-acetyl-p-aminophenol, APAP) ALI, or INR≥2.0, ALT≥10x elevated, and bilirubin≥3.0 mg/dl for non-APAP ALI, both groups without any discernible HE. Subjects who progressed to poor outcomes (ALF, death, LT) were compared, by univariate analysis, with those who recovered. A model to predict poor outcome was developed using the random forest (RF) procedure.Progression to a poor outcome occurred in 90/386 (23%), primarily in non-APAP (71/179, 40%) vs. only 14/194 (7.2%) in APAP patients comprising 52% of all cases (13 cases did not have an etiology assigned; 5 of whom had a poor outcome). Of 82 variables entered into the RF procedure: etiology, bilirubin, INR, APAP level and duration of jaundice were the most predictive of progression to ALF, LT, or death.A majority of ALI cases are due to APAP, 93% of whom will improve rapidly and fully recover, while non-APAP patients have a far greater risk of poor outcome and should be targeted for early referral to a liver transplant center.

A rapid and reliable point-of-care assay to detect acetaminophen protein adducts in the serum of patients with acute liver injury could improve diagnosis and management. AcetaSTAT is a competitive immunoassay used to measure acetaminophen protein adducts formed by toxic metabolites in serum samples from patients. We compared the accuracy of AcetaSTAT vs high-pressure liquid chromatography with electrochemical detection (HPLC-EC; a sensitive and specific quantitative analytic assay) to detect acetaminophen protein adducts.We collected serum samples from 19 healthy individuals (no liver injury, no recent acetaminophen use), 29 patients without acetaminophen-associated acute liver injury, and 33 patients with acetaminophen-associated acute liver injury participating in the Acute Liver Failure Study Group registry. Each serum sample was analyzed by AcetaSTAT (reported as test band amplitude) and HPLC-EC (the reference standard). We also collected data on patient age, sex, weight, level of alanine aminotransferase on test day and peak values, concentration of acetaminophen, diagnoses (by site investigator and causality review committee), and outcome after 21 days. Differences between groups were analyzed using the Fisher exact test for categoric variables and the Kruskal-Wallis test or rank-sum test for continuous variables.AcetaSTAT discriminated between patients with and without acetaminophen-associated acute liver injury; the median AcetaSTAT test band amplitude for patients with acetaminophen-associated acute liver injury was 584 (range, 222-1027) vs 3678 (range, 394-8289) for those without (P .001). AcetaSTAT identified patients with acetaminophen-associated acute liver injury with 100% sensitivity, 86.2% specificity, a positive predictive value of 89.2%, and a negative predictive value of 100%. Results from AcetaSTAT were positive in 4 subjects who received a causality review committee diagnosis of non-acetaminophen-associated acute liver injury; HPLC-EC and biochemical profiles were consistent with acetaminophen-associated acute liver injury in 3 of these cases.The competitive immunoassay AcetaSTAT shows a high degree of concordance with HPLC-EC results in identifying patients with acetaminophen-associated acute liver injury. This rapid and simple assay could increase early detection of this disorder and aid clinical management.

Numerous donor and recipient risk factors interact to influence the probability of survival after liver transplantation. We developed a statistic, D-MELD, the product of donor age and preoperative MELD, calculated from laboratory values. Using the UNOS STAR national transplant data base, we analyzed survival for first liver transplant recipients with chronic liver failure from deceased after brain death donors. Preoperative D-MELD score effectively stratified posttransplant survival. Using a cutoff D-MELD score of 1600, we defined a subgroup of donor-recipient matches with significantly poorer short- and long-term outcomes as measured by survival and length of stay (LOS). Avoidance of D-MELD scores above 1600 improved results for subgroups of high-risk patients with donor age >/=60 and those with preoperative MELD >/=30. D-MELD >/=1600 accurately predicted worse outcome in recipients with and without hepatitis C. There is significant regional variation in average D-MELD scores at transplant, however, regions with larger numbers of high D-MELD matches do not have higher survival rates. D-MELD is a simple, highly predictive tool for estimating outcomes after liver transplantation. This statistic could assist surgeons and their patients in making organ acceptance decisions. Applying D-MELD to liver allocation could eliminate many donor/recipient matches likely to have inferior outcome.

The recurrence of hepatocellular carcinoma (HCC) is a major cause of mortality for patients transplanted with HCC. There currently exists no standard method for identifying those patients with a high risk for recurrence. Identification of factors leading to recurrence is necessary to develop an efficient surveillance protocol and address new potential adjuvant therapies. We conducted a retrospective review of 834 consecutive liver transplants from 1/1/1996 to 12/31/2005 (mean follow-up 1303 ± 1069 days) at one institution and 352 consecutive transplants from 1/2/2002 to 12/31/2005 (mean follow-up 836 ± 402 days) at a second institution. The test cohort comprised patients identified with HCC in their explanted livers from 1/1/2001 to 12/31/2005 at the first institution. Explant pathology and donor and recipient characteristics were reviewed to determine factors associated with HCC recurrence. These predictors were validated in the remaining liver transplant recipients. The test cohort had 116 patients with findings of HCC in their explanted livers. Twelve patients developed recurrent HCC. Stepwise logistic regression identified 4 independent significant explant factors predictive of recurrence. Size of one tumor (>4.5 cm), macroinvasion, and bilobar tumor were positive predictors of recurrence, whereas the presence of only well-differentiated HCC was a negative predictor. Designating each significant factor with points in relation to its odds ratio, a Predicting Cancer Recurrence Score (PCRS) with results ranging from −3 to 6 was developed that accurately determined risk of recurrence. These findings were then applied to the two validation cohorts, which confirmed the high predictive value of this model. In conclusion, patients transplanted for HCC with a PCRS of ≤0 have a low risk of recurrence. Patients with a PCRS of 1 or 2 have a moderate risk of recurrence, and those with a PCRS of ≥3 have a high risk for recurrence. Liver Transpl 14:956–965, 2008. © 2008 AASLD.

Background & Aims Published estimates of survival associated with mushroom (amatoxin)-induced acute liver failure (ALF) and injury (ALI) with and without liver transplant (LT) are highly variable. We aimed to determine the 21-day survival associated with amatoxin-induced ALI (A-ALI) and ALF (A-ALF) and review use of targeted therapies. Methods Cohort study of all A-ALI/A-ALF patients enrolled in the US ALFSG registry between 01/1998 and 12/2014. Results Of the 2224 subjects in the registry, 18 (0.8%) had A-ALF (n = 13) or A-ALI (n = 5). At admission, ALF patients had higher lactate levels (5.2 vs. 2.2 mm, P = 0.06) compared to ALI patients, but INR (2.8 vs. 2.2), bilirubin (87 vs. 26 μm) and MELD scores (28 vs. 24) were similar (P > 0.2 for all). Of the 13 patients with ALF, six survived without LT (46%), five survived with LT (39%) and two died without LT (15%). Of the five patients with ALI, four (80%) recovered and one (20%) survived post-LT. Comparing those who died/received LT (non-spontaneous survivors [NSS]) with spontaneous survivors (SS), N-acetylcysteine was used in nearly all patients (NSS 88% vs. SS 80%); whereas, silibinin (25% vs. 50%), penicillin (50% vs. 25%) and nasobiliary drainage (0 vs. 10%) were used less frequently (P > 0.15 for all therapies). Conclusion Patients with mushroom poisoning with ALI have favourable survival, while around half of those presenting with ALF may eventually require LT. Further study is needed to define optimal management (including the use of targeted therapies) to improve survival, particularly in the absence of LT.

Purpose of review To review and highlight recent literature regarding the medical management of adult patients undergoing liver transplantation. Recent findings The addition of serum sodium concentration to the model for end-stage liver disease (MELD) score more accurately predicts 90-day waitlist mortality. Predictors of waitlist mortality and posttransplant survival include lower albumin and the presence of ascites, varices, and encephalopathy, as well as more nontraditional predictors such as older age, obesity, frailty, and sarcopenia. Indications for liver transplantation are evolving with the advent of effective therapy for hepatitis C and the increased prevalence of nonalcoholic steatohepatitis. Disparities persist in the current allocation system, including geographic variation and MELD inflation for hepatocellular carcinoma. Share 35 allows for broader regional sharing of organs for patients with the highest need, without detrimental effects on waitlist mortality or survival. Everolimus is a recently approved option for posttransplant immunosuppression that spares renal function. Summary The MELD score has enabled the liver transplant community to equitably allocate organs. Recent literature has focused on the limitations of the MELD score and the disparities inherent in the current system. The next steps for liver transplantation will be to develop strategies to further optimize waitlist prioritization and organ allocation.

Background: Noninvasive markers of hepatic fibrosis hold great promise to stage liver fibrosis and to monitor disease progression. To date, few studies have assessed the performance of the currently available markers of hepatic fibrosis in HIV-infected cohorts. The aim of the current study was to compare the diagnostic performance and characteristics of a number of noninvasive markers of hepatic fibrosis in populations of hepatitis C virus (HCV)-infected patients with and without HIV infection. Methods: A sample of 97 subjects (40 HCV/HIV-coinfected, 57 HCV-infected) undergoing liver biopsy as part of an ongoing prospective cohort study was evaluated. Liver biopsies were assessed by a single hepatopathologist and scored according to Ishak criteria. Noninvasive markers of fibrosis studied included international normalized ratio, platelet count, aspartate aminotransferase (AST)/alanine aminotransferase ratio, AST platelet ratio index (APRI), Forns index, procollagen III N peptide, hyaluronic acid, and YKL-40. Results: The correlations between fibrosis markers with the stage of fibrosis and the diagnostic performance of each of the tests were similar in the groups with and without HIV infection. Although a trend to improved diagnostic performance in the HCV/HIV-coinfected group was observed, this may be related to the small sample size. Conclusions: The diagnostic performance of the evaluated noninvasive markers of liver fibrosis is equivalent in HCV/HIV-coinfected and HCV-infected subjects. These tests may be of value for the clinical evaluation of HCV/HIV-coinfected patients and warrant further study.

There have been few reports of acute liver failure (ALF), with encephalopathy and coagulopathy, caused by infiltration of the liver by malignant cells. We describe a case series of 27 patients with ALF caused by malignancy. We examined a large, multicenter ALF registry (1910 patients; mean age, 47.1 ± 13.9 y) and found only 27 cases (1.4%) of ALF attributed to malignancy. Twenty cases (74%) presented with abdominal pain and 11 presented with ascites. The most common malignancies included lymphoma or leukemia (33%), breast cancer, (30%), and colon cancer (7%); 90% of the patients with lymphoma or leukemia had no history of cancer, compared with 25% of patients with breast cancer. Overall, 44% of the patients had evidence of liver masses on imaging. Diagnosis was confirmed by biopsy in 15 cases (55%) and by autopsy for 6 cases. Twenty-four patients (89%) died within 3 weeks of ALF.

UnlabelledWe report on the long-term intention-to-treat (ITT) outcome of 118 patients with hepatocellular carcinoma (HCC) undergoing downstaging to within Milan/United Network for Organ Sharing T2 criteria before liver transplantation (LT) since 2002 and compare the results with 488 patients listed for LT with HCC meeting T2 criteria at listing in the same period. The downstaging subgroups include 1 lesion >5 and ≤8 cm (n = 43), 2 or 3 lesions at least one >3 and ≤5 cm with total tumor diameter ≤8 cm (n = 61), or 4-5 lesions each ≤3 cm with total tumor diameter ≤8 cm (n = 14). In the downstaging group, 64 patients (54.2%) had received LT and 5 (7.5%) developed HCC recurrence. Two of the five patients with HCC recurrence had 4-5 tumors at presentation. The 1- and 2-year cumulative probabilities for dropout (competing risk) were 24.1% and 34.2% in the downstaging group versus 20.3% and 25.6% in the T2 group (P = 0.04). Kaplan-Meier's 5-year post-transplant survival and recurrence-free probabilities were 77.8% and 90.8%, respectively, in the downstaging group versus 81% and 88%, respectively, in the T2 group (P = 0.69 and P = 0.66, respectively). The 5-year ITT survival was 56.1% in the downstaging group versus 63.3% in the T2 group (P = 0.29). Factors predicting dropout in the downstaging group included pretreatment alpha-fetoprotein ≥1,000 ng/mL (multivariate hazard ratio [HR]: 2.42; P = 0.02) and Child's B versus Child's A cirrhosis (multivariate HR: 2.19; P = 0.04).ConclusionSuccessful downstaging of HCC to within T2 criteria was associated with a low rate of HCC recurrence and excellent post-transplant survival, comparable to those meeting T2 criteria without downstaging. Owing to the small number of patients with 4-5 tumors, further investigations are needed to confirm the efficacy of downstaging in this subgroup.

Transplant candidate caregivers (TCCs) are an under-utilized but potentially devoted pool of advocates who themselves may be recruited to register for deceased organ donation.The purpose of this study was to assess and compare recruitment barriers to deceased donor registration efforts in TCCs and health fair attendees (HFAs).A 42-item questionnaire assessing willingness to register as an organ donor and perceptions and knowledge about organ donation was administered to 452 participants (174 in Denver, 278 in San Francisco). Logistic regression, stratified by study site, was used to assess associations between explanatory variables and willingness to register as an organ donor.In Denver, 83 % of TCCs versus 68 % of HFAs indicated a willingness to register (p = 0.03). Controlling for study group (TCC vs HFA), predictors of willingness to register were female gender [odds ratio (OR) 2.4], Caucasian race (OR 2.3), college graduate (OR 11.1), married (OR 2.4) and higher positive perception of organ donation (OR 1.2), each p0.05. In San Francisco, 58 % of TCCs versus 70 % of HFAs indicated a willingness to register (p = 0.03). Controlling for study group (TCC vs HFA), predictors of willingness to register were Caucasian race (OR 3.5), college graduate (OR 2.2), married (OR 1.9), higher knowledge (OR 1.6) and higher positive perception of organ donation (OR 1.2), each p0.05. In both locales, Caucasians were more likely to have positive perceptions about organ donation and were more willing to register.Demographic characteristics, not personal connection to a transplant candidate, explain willingness to register as an organ donor.

Introduction Acute liver failure (ALF) is an ideal condition for use of a checklist. Our aims were to develop a checklist for the management of ALF in the intensive care unit (ICU) and assess the usability of the checklist among multiple providers. Methods The initial checklist was developed from published guidelines and expert opinion. The checklist underwent pilot testing at 11 academic liver transplant centers in the US and Canada. An anonymous, written survey was used to assess the usability and quality of the checklist. Written comments were used to improve the checklist following the pilot testing period. Results We received 81 surveys involving the management of 116 patients during the pilot testing period. The overall quality of the checklist was judged to be above average to excellent by 94% of users. On a 5-point Likert scale, the majority of survey respondents agreed or agreed strongly with the following checklist characteristics: the checklist was easy to read (99% agreed/agreed strongly), easy to use (97%), items are categorized logically (98%), time to complete the checklist did not interfere with delivery of appropriate and safe patient care (94%) and was not excessively burdensome (92%), the checklist allowed the user the freedom to use his or her clinical judgment (80%), it is a useful tool in the management of acute liver failure (98%). Web-based and mobile apps were developed for use of the checklist at the point of care. Conclusion The checklist for the management of ALF in the ICU was shown in this pilot study to be easy to use, helpful and accepted by a wide variety of practitioners at multiple sites in the US and Canada.

The development of pulmonary arterial hypertension in the setting of portal hypertension is known as portopulmonary hypertension. Portal hypertension is thought to predispose patients to disturbances in the homeostatic regulation of numerous neurohumoral and vasoactive mediators that induce the development of pulmonary arterial hypertension. Portopulmonary hypertension is pathologically indistinguishable from idiopathic pulmonary arterial hypertension and is characterized by the development of vasoconstriction, vascular remodeling, and thrombosis within the pulmonary vasculature. Although described in patients with both cirrhotic and noncirrhotic portal hypertension, portopulmonary hypertension is most prevalent among patients with end-stage liver disease, and its severity seems to be independent of the etiology or severity of liver disease. All liver transplant candidates must be screened for the presence of portopulmonary hypertension because of the high perioperative mortality risk of liver transplantation associated with this condition. Primary screening for portopulmonary hypertension consists of Doppler-estimated pulmonary artery systolic pressure measurement during echocardiography. However, the diagnosis of portopulmonary hypertension is based on unique hemodynamic criteria as determined by right heart catheterization. Untreated portopulmonary hypertension portends a poor prognosis, and the efficacy of current treatment modalities is limited. At present, the primary goals of therapy are to provide symptomatic relief, prolong survival, and improve pulmonary hemodynamics to facilitate safe and successful liver transplantation.

Introduction: Cavernous hemangiomas represent the most common benign primary hepatic neoplasm, often being incidentally detected. Although the majority of hepatic hemangiomas remain asymptomatic, symptomatic hepatic hemangiomas can present with abdominal pain, hemorrhage, biliary compression, or a consumptive coagulopathy. The optimal surgical management of symptomatic hepatic hemangiomas remains controversial, with resection, enucleation, and both deceased donor and living donor liver transplantation having been reported. Case Report: We report the case of a patient found to have a unique syndrome of multiorgan cavernous hemangiomatosis involving the liver, lung, omentum, and spleen without cutaneous involvement. Sixteen years following her initial diagnosis, the patient suffered from intra-abdominal hemorrhage due to her giant cavernous hepatic hemangioma. Evidence of continued bleeding, in the setting of Kasabach-Merritt Syndrome and worsening abdominal compartment syndrome, prompted MELD exemption listing. The patient subsequently underwent emergent liver transplantation without complication. Conclusion: Although cavernous hemangiomas represent the most common benign primary hepatic neoplasm, hepatic hemangioma rupture remains a rare presentation in these patients. Management at a center with expertise in liver transplantation is warranted for those patients presenting with worsening DIC or hemorrhage, given the potential for rapid clinical decompensation. © 2010 The Author(s).

Background The effect of patient education on bowel preparation for colonoscopy has not been well studied. An improvement in patient understanding of the rationale for bowel preparation before colonoscopy might enhance adherence to the prescribed bowel regimen and improve bowel preparation quality. Objective To measure the effect of a simple educational intervention on the quality of bowel preparation during colonoscopy. Design Prospective, single-center, endoscopist-blinded, randomized, controlled trial. Setting Tertiary-care center. Patients This study involved outpatients directly referred for screening colonoscopy. Intervention Inclusion of a visual aid depicting both clean and dirty colons in addition to standard written colonoscopy instructions. Main Outcome Measurements The primary outcome was the quality of the bowel preparation according to the Boston Bowel Preparation Scale (BBPS). Secondary outcomes included the need for repeat colonoscopy because of inadequate bowel preparation, insertion and withdrawal time, polyps detected, and patient tolerance of bowel preparation and colonoscopy. Results We analyzed 492 patients given a visual aid and 477 controls. The percentage of colonoscopies with a BBPS score ≥5 was similar in both groups (91% visual aid vs 89% control, P = .43). The odds ratio for having a BBPS ≥5 in the visual aid group was 1.24 (95% CI, 0.83-1.87) compared with controls. Other secondary outcomes were similar between groups. Limitations Single-center study. Conclusion A simple card with photographs and text explaining the rationale for bowel preparation did not change the quality of bowel preparation in patients directly referred for screening colonoscopy. Future educational studies may need to include more interactive or intensive methods. (Clinical trial registration number: NCT00643682.)

Noninvasive markers of liver fibrosis correlate with the stage of liver fibrosis, but have not been widely applied to predict liver-related mortality.We assessed the ability of two indices of liver fibrosis, aspartate aminotransferase (AST)-to-platelet ratio index (APRI) and Fib-4, and two markers of extracellular matrix metabolism, hyaluronic acid (HA) and YKL40, to predict liver mortality in a prospective cohort of hepatitis C virus (HCV)-infected individuals with and without HIV coinfection. These were compared with two established prognostic scores, the Child-Pugh-Turcotte (CPT) and model of end-stage liver disease (MELD) scores.A total of 303 subjects, of whom 207 were HIV positive at study entry, were followed up for a mean period of 3.1 years. There were 33 deaths due to liver disease. The ability of each test and score to predict 3-year liver mortality was expressed as the area under the receiver operator curve. The area under the receiver operator curve 95% confidence intervals were: HA 0.92 (0.86-0.96), CPT 0.91 (0.79-0.96), APRI 0.88 (0.80-0.93), Fib-4 0.87 (0.77-0.92), MELD 0.84 (71-0.91). In multivariate analyses HA, APRI, and fib-4 were independent predictors of mortality when included in models with MELD or CPT.Noninvasive markers of liver fibrosis are highly predictive of liver outcome in HCV-infected individuals with and without HIV coinfection. These markers seem to have a prognostic value independent of CPT and MELD.

Few bowel-preparation rating scales have been validated. Most scales were intended for comparing oral purgatives and fail to account for washing and/or suctioning by the endoscopist. This limits their utility in studies of colonoscopy outcomes, such as polyp-detection rates.To develop a valid and reliable scale for use in colonoscopy outcomes research.Academic medical center.We developed the Boston bowel preparation scale (BBPS), a 10-point scale that assesses bowel preparation after all cleansing maneuvers are completed by the endoscopist. We assessed interobserver and intraobserver reliability by using video footage of colonoscopies viewed on 2 separate occasions by 22 clinicians. We then applied the BBPS prospectively during screening colonoscopies and compared BBPS scores with clinically meaningful outcomes, including polyp-detection rates and procedure times.The intraclass correlation coefficient (a measure of interobserver reliability) for BBPS scores was 0.74. The weighted kappa (a measure of intraobserver reliability) for scores was 0.77 (95% CI, 0.66-0.87). During 633 screening colonoscopies, the mean (SD) BBPS score was 6.0 +/- 1.6. Higher BBPS scores (or =5 vs5) were associated with a higher polyp-detection rate (40% vs 24%, P.02). BBPS scores were inversely correlated with colonoscope insertion (r = -0.16, P.003) and withdrawal (r = -0.23, P.001) times.Single-center study.The BBPS is a valid and reliable measure of bowel preparation. It may be well suited to colonoscopy outcomes research because it reflects the colon's cleanliness during the inspection phase of the procedure.

The development of coagulopathy in acute liver failure (ALF) is universal. The severity of the coagulopathy is often assessed by determination of the prothrombin time and International Normalized Ratio (INR). In more than 1,000 ALF cases, the severity of the coagulopathy was moderate in 81% (INR 1.5–5.0), severe in 14% (INR 5.0–10.0), and very severe in 5% (INR > 10.0). Certain etiologies were associated with more severe coagulopathy, whereas ALF caused by fatty liver of pregnancy had the least severe coagulopathy. Management consisted of transfusions of FFP in 92%. Overall, FFP administered during the first week of admission amounted to 13.7 ± 15 units. Patients who received an ICP monitor had significantly more FFP transfused than those managed without ICP monitor (22.7 ± 2.4 vs. 12.3 ± 0.8 units FFP; P

Moderate to severe portopulmonary hypertension (PPHTN) increases the risks of orthotopic liver transplantation (OLT). Epoprostenol is an effective treatment of PPHTN, but long-term effects on pulmonary hemodynamics or liver function in PPHTN are poorly defined. We sought to describe the long-term effects of treatment with or without epoprostenol on pulmonary hemodynamics, liver biochemistries, and survival in patients with moderate to severe PPHTN at a single center. A large retrospective cohort was identified with moderate to severe PPHTN diagnosed before OLT. Baseline and follow-up pulmonary hemodynamics and liver biochemistries were compared and outcomes assessed. Nineteen patients were treated with epoprostenol and 17 were not treated with epoprostenol. There were significant improvements in mean pulmonary artery pressure (MPAP, 48.4-36.1 mm Hg; P < 0.0001), pulmonary vascular resistance (PVR, 632-282 dynes . s . cm(-5); P < 0.0001), and cardiac output (5.7 to 7.7 L/min; P = 0.0009) with epoprostenol after a median of 15.4 months. Liver biochemistries did not change significantly, and survival did not seem to differ between the 2 groups (hazard ratio, 0.85; P = 0.77). In the epoprostenol group, patients who survived had greater absolute changes in MPAP, transpulmonary gradient, and PVR than those who died. Two patients in the epoprostenol group successfully underwent OLT. Long-term epoprostenol therapy greatly improves pulmonary hemodynamics in patients with PPHTN. Liver biochemistries are not greatly changed. Survival seemed not to differ between treatment groups. A minority of patients treated with epoprostenol will improve sufficiently to undergo OLT.

Background Because acute liver failure (ALF) patients share many clinical features with severe sepsis and septic shock, identifying bacterial infection clinically in ALF patients is challenging. Procalcitonin (PCT) has proven to be a useful marker in detecting bacterial infection. We sought to determine whether PCT discriminated between presence and absence of infection in patients with ALF. Method Retrospective analysis of data and samples of 115 ALF patients from the United States Acute Liver Failure Study Group randomly selected from 1863 patients were classified for disease severity and ALF etiology. Twenty uninfected chronic liver disease (CLD) subjects served as controls. Results Procalcitonin concentrations in most samples were elevated, with median values for all ALF groups near or above a 2.0 ng/mL cut-off that generally indicates severe sepsis. While PCT concentrations increased somewhat with apparent liver injury severity, there were no differences in PCT levels between the pre-defined severity groups–non-SIRS and SIRS groups with no documented infections and Severe Sepsis and Septic Shock groups with documented infections, (p = 0.169). PCT values from CLD patients differed from all ALF groups (median CLD PCT value 0.104 ng/mL, (p ≤0.001)). Subjects with acetaminophen (APAP) toxicity, many without evidence of infection, demonstrated median PCT >2.0 ng/mL, regardless of SIRS features, while some culture positive subjects had PCT values

Liver transplantation (LT) candidates today are increasingly older, have greater medical acuity, and have more cardiovascular comorbidities than ever before. Steadily rising model for end-stage liver disease (MELD) scores at the time of transplant, resulting from high organ demand, reflect the escalating risk profiles of LT candidates. In addition to advanced age and the presence of comorbidities, there are specific cardiovascular responses in cirrhosis that can be detrimental to the LT candidate. Patients with cirrhosis requiring LT usually demonstrate increased cardiac output and a compromised ventricular response to stress, a condition termed cirrhotic cardiomyopathy. These cardiac disturbances are likely mediated by decreased beta-agonist transduction, increased circulating inflammatory mediators with cardiodepressant properties, and repolarization changes. Low systemic vascular resistance and bradycardia are also commonly seen in cirrhosis and can be aggravated by beta-blocker use. These physiologic changes all contribute to the potential for cardiovascular complications, particularly with the altered hemodynamic stresses that LT patients face in the immediate post-operative period. Post-transplant reperfusion may result in cardiac death due to a multitude of causes, including arrhythmia, acute heart failure, and myocardial infarction. Recognizing the hemodynamic challenges encountered by LT patients in the perioperative period and how these responses can be exacerbated by underlying cardiac pathology is critical in developing recommendations for the pre-operative risk assessment and management of these patients. The following provides a review of the cardiovascular challenges in LT candidates, as well as evidence-based recommendations for their evaluation and management.
