Abstract
Over the last decades, liver transplantation (LT) has evolved into a life-saving procedure. Due to limited deceased donor activities in the eastern world, living donor liver transplantation (LDLT) had flourished tremendously in most Asian countries. Yet, these LDLT activities fall short of meeting the expected demands. Pakistan, a developing country, bears a major burden of liver diseases. Currently, only few centers offer LDLT services in the country. On the other hand, deceased donor liver transplantation (DDLT) activities have not started due to social, cultural, and religious beliefs. Various strategies can be adopted successfully to overcome the scarcity of live liver donors (LLDs) and to expand the donor pool, keeping in view donor safety and recipient outcome. These include consideration of LLDs with underlying clinical conditions like G6PD deficiency and Hepatitis B core positivity. Extended donor criteria can also be utilized and relaxation can be made in various donors' parameters including upper age and body mass index after approval from the multidisciplinary board. Also, left lobe grafts, grafts with various anatomical variations, and a low graft-to-recipient ratio can be considered in appropriate situations. ABO-incompatible LT and donor swapping at times may help in expanding the LLDs pool. Similarly, legislation is needed to allow live non-blood-related donors for organ donations. Finally, community education and awareness through various social media flat forms are needed to promote deceased organ donation.

Abstract
Although liver transplantation (LT) recipients are at high cardiovascular risk (CVR), the management of CVR factors (CVRF) after LT is far from optimal and needs to be improved. For this reason, we developed a multidisciplinary protocol to standardize the identification, risk stratification, management, and targets of therapy of CVRF during the first post-LT year. The grade of identification and control of CVRF 12 months after LT in the postintervention cohort (LT January 2018-January 2020, n = 150) were compared with a control cohort who underwent LT between July 2015 and December 2016 (n = 100). Before LT, the prevalence of metabolic-associated fatty liver disease as the indication of LT and the presence of obesity were significantly higher in the postintervention cohort, whereas the prevalence of other CVRF and renal dysfunction tended to be higher. Cyclosporine A was used less frequently in the postintervention cohort, whereas everolimus tended to increase. At 12 months after LT, the proportion of patients with measured blood pressure (88% vs. 56%), glycosilated hemoglobin (HbA1c; 96% vs. 72%), and high-density lipoprotein/low-density lipoprotein cholesterol (67% vs. 33%) was higher in the postintervention than in the control cohort (all p < 0.001). Blood pressure (64% vs. 36%, p = 0.02) and HbA1c (85% vs. 70%, p = 0.1) were within target in more individuals with hypertension and diabetes mellitus, respectively, in the postintervention cohort. Median total cholesterol levels were lower in the postintervention (184 mg/dl; interquartile range [IQR], 160-210 mg/dl) than in the control cohort (212 mg/dl; IQR, 186-240 mg/dl; p = 0.02). At 2 years after LT, the incidence of cardiovascular events was 14% in the control cohort and 6% in the postintervention cohort (p = 0.063). In conclusion, a multidisciplinary, multiprofessional strategy can achieve a higher grade of assessment and management of post-LT CVR despite a worsening metabolic profile of LT recipients.

Abstract
ZusammenfassungDie Lebertransplantation ist die einzige kurative Therapieoption einer chronischen Leberinsuffizienz im Endstadium. Daneben stellen onkologische Lebererkrankungen wie das HCC eine weitere
Indikation für die Lebertransplantation dar, ebenso wie das akute Leberversagen.Seit der ersten erfolgreichen Lebertransplantation durch Professor Thomas E. Starzl im Jahr 1967 haben sich nicht nur die chirurgischen, immunologischen und anästhesiologischen Techniken
und Möglichkeiten geändert, sondern auch die Indikationen und das Patientengut. Hinzu kommt, dass die Empfänger ein zunehmendes Lebensalter und damit einhergehend mehr Begleiterkrankungen
aufweisen.Die Zahl an Lebertransplantationen ist weltweit weiter ansteigend. Es benötigen aber mehr Menschen eine Lebertransplantation, als Organe zur Verfügung stehen. Dies liegt am zunehmenden
Bedarf an Spenderorganen bei gleichzeitig weiter rückläufiger Zahl postmortaler Organspenden.Diese Diskrepanz zwischen Spenderorganen und Empfängern kann nur zu einem kleinen Teil durch Split-Lebertransplantationen oder die Leberlebendspende kompensiert werden.Um den Spenderpool zu erweitern, werden zunehmend auch marginale Organe, die nur die erweiterten Spenderkriterien („extended donor criteria [EDC]“) erfüllen, allokiert. In manchen Ländern
zählen hierzu auch die sogenannten DCD-Organe (DCD: „donation after cardiac death“), d. h. Organe, die erst nach dem kardiozirkulatorischen Tod des Spenders entnommen werden.Es ist bekannt, dass marginale Spenderorgane mit einem erhöhten Risiko für ein schlechteres Transplantat- und Patientenüberleben nach Lebertransplantation einhergehen.Um die Qualität marginaler Spenderorgane zu verbessern, hat sich eine rasante Entwicklung der Techniken der Organkonservierung über die letzten Jahre gezeigt. Mit der maschinellen
Organperfusion besteht beispielsweise die Möglichkeit, die Organqualität deutlich zu verbessern. Insgesamt haben sich die Risikokonstellationen von Spenderorgan und Transplantatempfänger
deutlich geändert.Aus diesem Grunde ist es von großer Bedeutung, spezifische Prädiktoren für eine erfolgreiche Lebertransplantation sowie die entsprechenden Risikofaktoren für einen schlechten postoperativen
Verlauf zu kennen, um das bestmögliche Transplantat- und Patientenüberleben nach Lebertransplantation zu ermöglichen.Diese Einflussfaktoren, inklusive möglicher Risiko-Scores, sollen hier ebenso wie die neuen technischen Möglichkeiten in der Lebertransplantation beleuchtet werden.

Abstract
The quality and size of liver grafts are critical factors that influence living‐donor liver transplantation (LDLT) function and safety. However, the biomarkers used for predicting graft quality are lacking. In this study, we sought to identify unique graft quality markers, aside from donor age, by using the livers of non‐human primates. Hepatic gene microarray expression data from young and elderly cynomolgus macaques revealed a total of 271 genes with significantly increased expression in the elderly. These candidate genes were then narrowed down to six through bioinformatics analyses. The expression patterns of these candidate genes in human donor liver tissues were subsequently examined. Importantly, we found that grafts exhibiting up‐regulated expression of these six candidate genes were associated with an increased incidence of liver graft failure. Multivariable analysis further revealed that up‐regulated expression of LRRN2 (encoding leucine‐rich repeat protein, neuronal 2) in donor liver tissue served as an independent risk factor for graft failure (odds ratio 4.50, confidence interval 2.08–9.72). Stratification based on graft expression of LRRN2 and donor age was also significantly associated with 6‐month graft survival rates. Conclusion: Up‐regulated LRRN2 expression of liver graft is significantly correlated with graft failure in LDLT. In addition, combination of graft LRRN2 expression and donor age may represent a promising marker for predicting LDLT graft quality.

Abstract
Monitoring specific underlying causes of death in solid organ transplant (SOT) recipients is important in order to identify emerging trends and health challenges. This retrospective cohort study includes all SOT recipients transplanted at Rigshospitalet between January 1st, 2010 and December 31st, 2019. The underlying cause of death was determined using the newly developed Classification of Death Causes after Transplantation (CLASS) method. Cox regression analyses assessed risk factors for all-cause and cause-specific mortality. Of the 1774 SOT recipients included, 299 patients died during a total of 7511 person-years of follow-up (PYFU) with cancer (N = 57, 19%), graft rejection (N = 55, 18%) and infections (N = 52, 17%) being the most frequent causes of death. We observed a lower risk of all-cause death with increasing transplant calendar year (HR 0.91, 95% CI 0.86–0.96 per 1-year increase), alongside death from graft rejection (HR 0.84 per year, 95% CI 0.74–0.95) and death from infections (HR 0.86 per year, 95% CI 0.77–0.97). Further, there was a trend towards lower cumulative incidence of death from cardiovascular disease, graft failure and cancer in more recent years, while death from other organ specific and non-organ specific causes did not decrease. All-cause mortality among SOT recipients has decreased over the past decade, mainly due to a decrease in graft rejection- and infection-related deaths. Conversely, deaths from a broad range of other causes have remained unchanged, suggesting that cause of death among SOT recipients is increasingly diverse and warrants a multidisciplinary effort and attention in the future.

The New Age of Organ Donation-What Factors Have an Influence on the Attitude of Older People? An Attitudinal Survey in Southeastern Spain. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 19:ijerph19148524.

Abstract
Currently, more than half of all donors are aged over 65 years, and previous studies have shown that this group is less willing to support organ donation. Objective: to analyse the attitude of people aged over 65 years toward organ donation and transplantation (ODT) and to determine how their psychosocial profile affects their attitude. Study population: citizens residing in southeastern Spain older than 65 years of age. A representative sample was obtained, which was stratified by gender and geographical location (n = 420). A validated questionnaire about ODT was used. Statistical analysis: a bivariate analysis was performed using the X2 test and a multivariate analysis. The favourable attitude toward the donation of one’s own organs was 53%. The psychosocial variables affecting attitude were mainly: having discussed ODT with one’s family (p < 0.001) or friends (OR 2.223), acceptance of cremation (OR 2.508), and acceptance of an autopsy (OR 2.578). Citizens aged over 65 tend to have an unfavourable attitude toward the donation of their own organs. The lack of dialogue about ODT in social and family settings, and the attitude to the manipulation of one’s own body after death, are aspects of a respondent’s psychosocial profile, which influence this attitude.

Abstract
BACKGROUND Evidence for use of graft from older donors in living donor liver transplantation (LDLT) has been conflicting. This study aims to clarify the impact of donor age on recipient morbidity and mortality after adult LDLT. METHODS A total of 90 live liver donors and recipients who underwent primary adult-to-adult LDLT were divided into three groups according to donor age: donors in 20s (D-20s) group, donors in 30s and 40s (D-30s and 40s) group and donors in 50s & 60s (D-50s and 60s) group. Multivariate analyses were conducted to look for independent risk/prognostic factors. Donor age was analysed as a continuous variable to determine an optimal cut off. RESULTS Overall donor morbidity was 4/90 (4.44%), major donor morbidity was 1/90 (1.11%) and there was no donor mortality. Recipients in the D-20s group had better 1-, 3- and 5-year recipient survival than recipients in the D-50s and 60s group (96%, 91%, 91% versus 73%, 58%, 58%, respectively) (P = 0.020). Donor age was identified to be an independently significant risk factor for increased major complications (P = 0.007) and prognostic factor for reduced overall survival (P = 0.014). The optimal donor age cut off was determined to be 46.5 years old. CONCLUSION Older donors are associated with poorer recipient outcomes after adult-to-adult LDLT. Usage of liver grafts from older donors should be carefully considered when choosing liver grafts for patients undergoing LDLT.

Abstract
As the US population ages, more elderly patients may need liver transplantation. Our aim was to assess recent trends among elderly individuals requiring liver transplant in the United States. Scientific Registry of Transplant Recipients data (2002-2020) were used to select elderly (≥65 years) liver transplant candidates and assess on-list and posttransplant outcomes. During the study period, 31,209 liver transplant candidates ≥65 years were wait listed. Common etiologies included nonalcoholic steatohepatitis (NASH; 31%), hepatitis C (23%), and alcoholic liver disease (18%); 30% also had hepatocellular carcinoma (HCC). Over time, the proportion of patients ≥65 years among all adult liver transplant candidates increased from 9% (2002-2005) to 23% (2018-2020) (trend, p < 0.0001). The proportion of NASH among elderly candidates increased from 13% (2002-2005) to 39% (2018-2020). Of the elderly candidates, 54% eventually received transplants. In multivariate analysis, independent predictors of a higher chance of receiving a transplant for the elderly included more recent years of listing, male sex, higher Model for End-Stage Liver Disease (MELD) score, and HCC (all p < 0.01). Posttransplant mortality in elderly transplant recipients was higher than in younger patients but continued to decrease over time. In multivariate analysis, independent predictors of higher posttransplant mortality for elderly transplant recipients were earlier years of transplantation, older age, male sex, higher MELD score, history of diabetes, retransplantation, and having HCC (all p < 0.01). The proportion of elderly patients in need of liver transplantation in the United States is sharply increasing. NASH is the most common indication for liver transplantation among the elderly. The outcomes of these patients have been improving in the past 2 decades.

Abstract
BACKGROUND This study aimed to assess the differences between the United States and the United Kingdom in the characteristics and posttransplant survival of patients who received donation after circulatory death (DCD) liver allografts from donors aged >60 y. METHODS Data were collected from the UK Transplant Registry and the United Network for Organ Sharing databases. Cohorts were dichotomized into donor age subgroups (donor >60 y [D >60]; donor ≤60 y [D ≤60]). Study period: January 1, 2001, to December 31, 2015. RESULTS 1157 DCD LTs were performed in the United Kingdom versus 3394 in the United States. Only 13.8% of US DCD donors were aged >50 y, contrary to 44.3% in the United Kingdom. D >60 were 22.6% in the United Kingdom versus 2.4% in the United States. In the United Kingdom, 64.2% of D >60 clustered in 2 metropolitan centers. In the United States, there was marked inter-regional variation. A total of 78.3% of the US DCD allografts were used locally. One- and 5-y unadjusted DCD graft survival was higher in the United Kingdom versus the United States (87.3% versus 81.4%, and 78.0% versus 71.3%, respectively; P < 0.001). One- and 5-y D >60 graft survival was higher in the United Kingdom (87.3% versus 68.1%, and 77.9% versus 51.4%, United Kingdom versus United States, respectively; P < 0.001). In both groups, grafts from donors ≤30 y had the best survival. Survival was similar for donors aged 41 to 50 versus 51 to 60 in both cohorts. CONCLUSIONS Compared with the United Kingdom, older DCD LT utilization remained low in the United States, with worse D >60 survival. Nonetheless, present data indicate similar survivals for older donors aged ≤60, supporting an extension to the current US DCD age cutoff.

Abstract
The prognostic role of cardiac dysfunction in cirrhotic patients is increasingly recognised. We studied its impact on morbidity and mortality before and after liver transplantation (LT) including development of post-transplant cardiovascular disease (CVD). In this retrospective study, cirrhotic patients who underwent LT assessment from January 2010 to December 2020 were reviewed. Demographics, cardiac investigations and clinical course were analysed to identify prevalence of cardiac dysfunction and its role in LT outcomes. Survival analysis was performed using Cox proportional hazard regression modelling, with LT as a time-varying covariate and as an interaction variable with cardiac dysfunction. 308 patients (70% male) were studied. The median (interquartile range) age at LT assessment was 56 (12) years. Cardiac dysfunction was found in 178 (58%) patients (diastolic, 169; systolic, 26; both, 17) and was significantly associated with hepatorenal syndrome/acute kidney injury and peri- and post-transplant morbidity (adjusted odds ratio [aOR] 1.94, 95%CI 1.06-3.52, p < 0.001; aOR 2.01, 95%CI 1.06-3.82, p = 0.033; aOR 1.9, 95%CI 1.01-3.65, p = 0.023, respectively). Cardiac dysfunction was not associated with mortality before (adjusted hazard ratio [aHR] 1.01, 95% CI 0.99-1.01) or after LT (aHR 0.74, 95% CI 0.4-1.05. Post-transplant CVD (61% cardiac failure) occurred in 36 patients and there was no significant association with cardiac dysfunction (p = 0.11). Cardiac dysfunction was common in LT candidates and was significantly associated with morbidity before and after LT. Studies on the role of advanced echocardiographic parameters to improve diagnosis of cardiac dysfunction and optimise LT outcomes are needed. This article is protected by copyright.

Introduction of a standardized protocol for cardiac risk assessment in candidates for liver transplant - A retrospective cohort analysis. Ann Hepatol 2022; 27:100582. [PMID: 34808392 DOI: 10.1016/j.aohep.2021.100582] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/11/2021] [Revised: 09/27/2021] [Accepted: 10/11/2021] [Indexed: 02/08/2023]
Abstract
INTRODUCTION Recommendations on non-invasive imaging to assess pre-operative cardiac risk among liver transplant candidates vary amongst societal guidelines and individual institutional practices. In 2018, a standardized pre-transplant coronary evaluation protocol was established at Beth Israel Deaconess Medical Center, Boston MA, to ensure appropriate and consistent pre-operative testing was performed. METHODS All patients who underwent liver transplant evaluation between January 1st, 2016 and December 31st, 2019, were retrospectively analyzed and divided into three cohorts; before the introduction of the protocol (prior to 2018), initial protocol favoring invasive coronary angiography (ICA) (2018), and amended protocol favoring coronary computed tomography angiography (CCTA) (post-2018). We described clinical characteristics, candidacy for transplant, and cardiovascular complications during follow-up. As an unadjusted exploratory analysis, the Cochran-Armitage Exact Trend Test was used to examine univariate differences across time. RESULTS A total of 462 patients underwent liver transplant evaluation during the study period. Among these, 218 (47.2%) patients underwent stress test, 50 (10.8%) underwent CCTA, and 68 (14.8%) underwent ICA. Across the three time periods, there was an increase in the proportion of CCTAs performed (3%, 6.3%, and 26.3% respectively; p <0.001) and proportion of patients diagnosed with obstructive CAD using CCTA (0%, 30%, and 51.4% respectively; p = 0.04). There was no significant difference in post-transplant cardiac complications among patients evaluated before 2018, during 2018, and after 2018 (5.9% vs. 5.6 vs. 6.0%; p=1.0). CONCLUSION Our findings suggest it is reasonable to shift practice to a less invasive approach utilizing CCTA or nuclear stress testing when assessing liver transplant candidates at increased cardiovascular risk.

A Meta-Analysis and Systematic Review on the Global Prevalence, Risk Factors, and Outcomes of Coronary Artery Disease in Liver Transplantation Recipients. Liver Transpl 2022; 28:689-699. [PMID: 34626045 DOI: 10.1002/lt.26331] [Citation(s) in RCA: 8] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/09/2021] [Revised: 10/02/2021] [Accepted: 10/06/2021] [Indexed: 12/12/2022]
Abstract
The shift in the changing etiology of cirrhosis requiring liver transplantation (LT) has resulted in an increasing prevalence of coronary artery disease (CAD) that can potentially impact post-LT outcomes. This systematic review and meta-analysis evaluates the prevalence of CAD, risk factors, and outcomes of patients diagnosed with CAD before LT. MEDLINE and EMBASE were searched for articles describing CAD in pre-LT patients. Meta-analysis of proportions using the generalized linear mix model was conducted to analyze the pooled prevalence of CAD in pre-LT patients. Associated risk factors for CAD in pre-LT patients and outcomes were evaluated in conventional pairwise meta-analysis. A total of 39 studies were included. The pooled prevalence of patients diagnosed with CAD before LT was 15.9% (95% CI, 9.8%-24.7%). Age, male sex, diabetes mellitus, hypertension, hyperlipidemia, smoking, nonalcoholic steatohepatitis, hepatitis B virus, and hepatocellular carcinoma were significantly associated with CAD. Patients from high-income countries especially North America, Europe, and South America, with the associated risk factors were at increased risk for CAD before LT. CAD before LT was associated with an increased odds of overall mortality (odds ratio [OR], 1.4; 95% confidence interval [CI], 1.4-1.4; P = 0.01) and cardiac-related mortality (OR, 1.2; 95% CI, 1.1-1.3; P = 0.03). A total of 48.7% of included articles considered the presence of cardiovascular risk factors for CAD screening. However, 10.3% of the studies screened for CAD in pre-LT patients via invasive coronary angiography only, without stress testing or risk stratification. This study demonstrates the high prevalence of CAD in pre-LT patients, associated risk factors, and outcomes. There is heterogeneity among guidelines and practice in screening for pre-LT CAD, and more studies are needed to establish consensus.

Abstract
With long-term survival after liver transplantation becoming the rule, care for medical problems arising over time in liver-transplanted patients gained increasing importance. The most common causes of death occurring more than 1 year after liver transplantation are unrelated to liver diseases and facilitated by immunosuppressive treatments; examples are malignancies, renal failure, and cardiovascular, metabolic, and infectious diseases. Recipients receive life-long follow-up care at transplant centers, however, the increasing number of liver-transplanted patients is saturating the health care supply that transplant centers have to offer. Primary care physicians are increasingly exposed to liver-transplanted patients, even in the early periods after transplant, and an understanding of the most common risks and complications faced by these patients would enhance their care. This article reviews the long-term care of liver transplant recipients, emphasizing the key internal medicine-related issues that should be known by primary care physicians. A specific section is devoted to implementing strategies to involve these physicians in the long-term follow-up of liver-transplanted patients in close collaboration with transplant hepatologists.

Abstract
PURPOSE OF REVIEW As the population of the world is aging the number of geriatric patients undergoing liver transplantation (LT) is also increasing. They pose a unique challenge for the caregivers, as they have age-related physiological changes, multiple comorbidities and cirrhosis-related pathologies. RECENT FINDINGS Twenty-two percent of patients who undergo LT are older than 65 years. Many patients suffer from nonalcoholic steatohepatitis (NASH), hepatocellular carcinoma and hepatitis-C virus. Incidence of NASH tends to increase with age, obesity, diabetes and metabolic syndrome. Elderly patients require comprehensive cognitive, cardiac and pulmonary evaluation prior to LT. Cirrhotic cardiomyopathy, hepatopulmonary syndrome, portopulmonary hypertension and frailty are of specific concern. SUMMARY Proportion of elderly patients who are undergoing LT continues to increase. These patients require comprehensive cardiopulmonary and frailty evaluation. Consensus-based practice advisories need to be developed to standardize preoperative evaluation of geriatric patients awaiting LT.

Abstract
Liver transplantation (LT), the only cure for end-stage liver disease, is a lifesaving, costly, and limited resource. LT recipients (LTRs) are aging with an increasing burden of medical comorbidities. Patient and graft survival rates exceed 70% at 5 years; however, patient-centered health outcomes beyond survival have received relatively little attention. LTRs must have strong self-management skills to navigate health systems, adhere to clinical monitoring, and take complex, multidrug regimens. All of these tasks require formidable cognitive abilities for active learning and problem solving. Yet, LTRs are at higher risk for impaired cognition as a result of the high prevalence of pretransplant hepatic encephalopathy, multiple chronic conditions, alcohol use, physical frailty, sarcopenia, and older age. Cognitive impairment after transplant may persist and has been causally linked to poor self-management skills, worse physical function, and inferior health outcomes in other health care settings, yet its impact after LT is largely unknown. There is a need to study potentially modifiable, posttransplant targets including caregiver support, physical activity, sleep, and treatment adherence to inform future health system responses to promote the long-term health and well-being of LTRs. Prospective, longitudinal data collection that encompasses key sociodemographic, cognitive-behavioral, psychosocial, and medical factors is needed to improve risk prediction and better inform patient and caregiver expectations. Interventions with proactive monitoring, reducing medical complexity, and improved care coordination can be tailored to optimize posttransplant care. We propose a research agenda focused on understudied, potentially modifiable risk factors to improve the long-term health of LTRs. Our conceptual model accounts for cognitive function, caregiver and patient self-management skills, health behaviors, and patient-centered outcomes beyond mortality. We propose actionable health-system, patient, and caregiver-directed interventions to fill knowledge gaps and improve outcomes.

Abstract
BACKGROUND & AIMS The concept of benchmarking is established in the field of transplant surgery; however, benchmark values for donation after circulatory death (DCD) liver transplantation are not available. Thus, we aimed to identify the best possible outcomes in DCD liver transplantation and to propose outcome reference values. METHODS Based on 2,219 controlled DCD liver transplantations, collected from 17 centres in North America and Europe, we identified 1,012 low-risk, primary, adult liver transplantations with a laboratory MELD score of ≤20 points, receiving a DCD liver with a total donor warm ischemia time of ≤30 minutes and asystolic donor warm ischemia time of ≤15 minutes. Clinically relevant outcomes were selected and complications were reported according to the Clavien-Dindo-Grading and the comprehensive complication index (CCI). Corresponding benchmark cut-offs were based on median values of each centre, where the 75th-percentile was considered. RESULTS Benchmark cases represented between 19.7% and 75% of DCD transplantations in participating centres. The 1-year retransplant and mortality rates were 4.5% and 8.4% in the benchmark group, respectively. Within the first year of follow-up, 51.1% of recipients developed at least 1 major complication (≥Clavien-Dindo-Grade III). Benchmark cut-offs were ≤3 days and ≤16 days for ICU and hospital stay, ≤66% for severe recipient complications (≥Grade III), ≤16.8% for ischemic cholangiopathy, and ≤38.9 CCI points 1 year after transplant. Comparisons with higher risk groups showed more complications and impaired graft survival outside the benchmark cut-offs. Organ perfusion techniques reduced the complications to values below benchmark cut-offs, despite higher graft risk. CONCLUSIONS Despite excellent 1-year survival, morbidity in benchmark cases remains high. Benchmark cut-offs targeting morbidity parameters offer a valid tool to assess the protective value of new preservation technologies in higher risk groups and to provide a valid comparator cohort for future clinical trials. LAY SUMMARY The best possible outcomes after liver transplantation of grafts donated after circulatory death (DCD) were defined using the concept of benchmarking. These were based on 2,219 liver transplantations following controlled DCD donation in 17 centres worldwide. Donor and recipient combinations with higher risk had significantly worse outcomes. However, the use of novel organ perfusion technology helped high-risk patients achieve similar outcomes as the benchmark cohort.

The impact of older age on long term survival in living donor liver transplantation: A propensity score matching analysis. Asian J Surg 2021; 45:2239-2245.

Abstract
BACKGROUND Prevalence of the end-stage liver disease in the elderly patients indicating a liver transplantation (LT) has been increasing. There is no universally accepted upper age limit for LT candidates but the functional status of older patients is important in pre-LT evaluation. This study aimed to examine the impact of older age on survival after living donor liver transplantation (LDLT). METHOD A total of 171 LDLT recipients were assessed in two groups: age ≥65 and < 65. To eliminate selection bias propensity score matching (PSM) was performed, and 56 of 171 recipients were included in this study. RESULTS There were 20 recipients in the older group and 36 in the younger. The 1-, 3-, and 5-year survival rates were 65.0%, 60.0%, and 60.0% in group 1; 88.9%, 84.7%, and 71.4% in group 2, respectively. The 1-year survival was significantly lower in the older recipients; however, overall survival rates were similar between the groups. Of the 56 recipients, 15 (27%) deaths were observed in overall, and 11 (20%) in 1-year follow-up. The univariate regression analysis after PSM revealed that MELD score affected 1- year survival and the multivariate analysis revealed that age ≥65 years and MELD score were the predictors of 1-year survival. CONCLUSION At first sight, before PSM, survival appeared to be worse for older recipients. However, we have shown that there were confounding effects of clinical variables in the preliminary evaluation. After the elimination of this bias with PSM, This study highlights that older recipients have similar outcomes as youngers in LDLT for long-term survival.

Abstract
Elderly liver transplant (LTx) recipients at a lower risk of acute rejection compared to younger recipients due to immunosenescence. As such, they may benefit from reduced immunosuppression (IS) to minimize infectious and malignant complications. We aimed to evaluate outcomes in LTx recipients ≥60 years compared to a younger group of LTx recipients aged 18-59 years maintained on a similar level of IS. This was a single-center retrospective evaluation of adult LTx recipients from 2013 to 2018 who received methylprednisolone induction and were maintained on tacrolimus, mycophenolate mofetil (MMF), and a prednisone taper. A total of 143 LTx recipients were evaluated. Mean age in the older group was 65 ± 3.8 compared to 49 ± 10.4 years in the younger group (p < 0.0001). Mean tacrolimus levels and the duration of MMF and steroids were comparable. Both groups had a similar incidence of first rejection within 1 year (19.2% in the elderly group vs. 23.1% in the younger group, p = 0.57). There were no statistical difference in terms of infection, malignancy, or patient survival. In conclusion, our data suggests that elderly LTx recipients, when treated with a similar level of IS, had similar 1 year incidence of rejection, infection, malignancy, and patient survival as younger LTx recipients.

Abstract
Aging involves progressive physiological and metabolic reprogramming to adapt to gradual deterioration of organs and functions. This includes mechanisms of defense against pre-malignant transformations. Thus, certain tumors are more prone to appear in elderly patients. This is the case of the two most frequent types of primary liver cancer, i.e., hepatocellular carcinoma (HCC) and intrahepatic cholangiocarcinoma (iCCA). Accordingly, aging hallmarks, such as genomic instability, telomere attrition, epigenetic alterations, altered proteostasis, mitochondrial dysfunction, cellular senescence, exhaustion of stem cell niches, impaired intracellular communication, and deregulated nutrient sensing can play an important role in liver carcinogenesis in the elders. In addition, increased liver fragility determines a worse response to risk factors, which more frequently affect the aged population. This, together with the difficulty to carry out an early detection of HCC and iCCA, accounts for the late diagnosis of these tumors, which usually occurs in patients with approximately 60 and 70 years, respectively. Furthermore, there has been a considerable controversy on what treatment should be used in the management of HCC and iCCA in elderly patients. The consensus reached by numerous studies that have investigated the feasibility and safety of different curative and palliative therapeutic approaches in elders with liver tumors is that advanced age itself is not a contraindication for specific treatments, although the frequent presence of comorbidities in these individuals should be taken into consideration for their management.

Abstract
Telemedicine gained interest in liver transplant patients but focused until now on the early post‐operative period. This prospective cohort study assessed feasibility, safety, and clinical beneficial effects of a telemedicine based remote monitoring program (TRMP) for the chronic follow‐up of adult liver transplant recipients. Between November 2017 and August 2019, a total of 87 of the 115 selected patients (76%) started the TRMP. Over the 2 years study period, none of the patients switched to standard follow‐up: 39/87 (45%) continued to do this autonomously and 48/87 (55%) stopped to report their data personally but communicated their lab values to the nurse. The other 28/115 (11%) patients who did not accept the TRMP continued the standard follow‐up. There was no difference in educational level between the three groups. Remote monitoring did not result in an increase in liver graft rejection and need of hospitalization. TRMP was associated with a higher number of tacrolimus level determinations and tacrolimus blood level concentrations could be kept lower. In conclusion, our results show that in patients with a stable clinical condition there is a high willingness to participate in TRMP and that this approach is safe. Remote monitoring allowed a stringent follow‐up of tacrolimus levels.

Abstract
BACKGROUND There is an increasing demand for total joint arthroplasty in liver transplantation patients. However, significant heterogeneity in existing studies creates difficulty to draw conclusions on the risk profile of arthroplasty in this population. METHODS A systematic review of the literature dated from 1980 to 2020 describing the complication rates of liver transplantation patients receiving either total hip or knee arthroplasty was conducted. Multiple outcomes were extracted and a meta-analysis was performed. Four cohorts were created for analysis purposes: liver transplant patients undergoing THA and TKA (1), THA only (2), TKA only (3), and controls (4). RESULTS A total of 13 studies were included in this meta-analysis, accounting for 3024 liver transplantation patients. The rate of infection (odds ratio [OR] = 2.14, OR = 1.61, OR = 2.52), myocardial infarction (OR = 1.65, OR = 1.75, OR = 1.57), respiratory failure (OR = 2.19, OR = 2.50, OR = 1.96), acute kidney injury (OR = 5.71, OR = 5.40, OR = 4.35), sepsis (OR = 3.72, OR = 3.30, OR = 4.02), and blood transfusions (OR = 2.09, OR = 3.65, OR = 1.74) were all significantly higher in the 3 cohorts compared to the controls. Revision/reoperation rates were significantly higher in cohorts 1 and 3 (OR = 1.52 and OR = 1.62, respectively). Patient-reported outcomes saw improvements in Harris Hip Score, objective Knee Society Score, and functional Knee Society Score postoperatively (average improvement = 32.4, 37.2, and 15.3, respectively). CONCLUSION Liver transplantation patients functionally benefit from total hip and knee arthroplasty, but at the cost of increased risk of infection, revision/reoperation, and medically related complications compared to controls. Mortality may also be a short-term risk.

Abstract
Although liver transplantation is considered to be the best choice for patients with end-stage liver diseases, postoperative immune rejection still cannot be overlooked. Patients with liver transplantation have to take immunosuppressive drugs for a long time or even their entire lives, in which heavy economic burden and side effects caused by the drugs have become the major impediment for liver transplantation. There is a growing body of evidences indicating that mesenchymal stem cell (MSC) transplantation, a promising tool in regenerative medicine, can be used as an effective way to induce immune tolerance after liver transplantation based on their huge expansion potential and unique immunomodulatory properties. MSCs have been reported to inhibit innate immunity and adaptive immunity to induce a tolerogenic microenvironment. In in vitro studies, transplanted MSCs show plasticity in immune regulation by altering their viability, migration, differentiation, and secretion in the interactions with the surrounding host microenvironment. In this review, we aim to provide an overview of the current understanding of immunomodulatory properties of MSCs in liver transplantation, to elucidate the potential mechanisms behind MSCs regulating immune response, especially in vivo and the influence of the microenvironment, and ultimately to discuss the feasible strategies to improve the clinical prognosis of liver transplantation. Only after exhaustive understanding of potential mechanisms of the MSC immunomodulation can we improve the safety and effectiveness of MSC treatment and achieve better therapeutic effects.

Abstract
The impact of increasing recipient age on morbidity and mortality following living donor liver transplantation (LDLT) remains controversial. The study aims to analyze the impact of recipient age on outcomes following LDLT. Data on adult LDLTs performed between November 2009 and February 2020 were retrieved from a prospectively maintained database. Patients were stratified into 2 groups based on recipient age: 18 to 65 years (younger adults) and >65 years (older adults). Propensity score matching (PSM) using nearest-neighbor matching was used to match each older recipient with up to 2 younger adult recipients using multiple preoperative parameters. Outcomes evaluated were duration of ventilation, need for reintubation, tracheostomy, intensive care unit (ICU) readmission, length of ICU and hospital stays, postoperative complications, reoperation within 90 days, and patient survival. A total of 801 adult LDLT recipients were included in the study; 751 (93.7%) were younger adults, and 50 (6.3%) were older adults. Older recipients were more likely to be diabetic (60.0% versus 39.7%) and hypertensive (44.0% versus 20.4%) with preexisting cardiac disease (28.0% versus 11.2%). However, their pretransplant Model for End-Stage Liver Disease score was significantly lower (14.5 versus 17.7), and they were more likely to receive a transplant because of hepatocellular carcinoma (38.0% versus 17.7%). Older recipients had longer durations of ventilation after LT both before (3.7 versus 1.9 days) and after PSM (4.0 versus 1.5 days). After PSM, the 30-day (13.0% versus 2.4%), 90-day (15.2% and 2.4%), and overall mortality rates (21.7% versus 7.1%) were significantly higher for older recipients when compared with younger recipients. There was no difference between the younger and older recipients with respect to other postoperative outcomes. This propensity score-matched study shows that the older LDLT recipients have higher 30-day, 90-day, 1-year, and 5-year mortality rates when compared with matched younger counterparts.

Abstract
Although the utilization of donation after circulatory death donors (DCDs) for liver transplantation (LT) has increased steadily, much controversy remains, and no common acceptance criteria exist with regard to donor and recipient risk factors and prediction models. A consensus conference was organized by International Liver Transplantation Society on January 31, 2020, in Venice, Italy, to review the current clinical practice worldwide regarding DCD-LT and to develop internationally accepted guidelines. The format of the conference was based on the grade system. International experts in this field were allocated to 6 working groups and prepared evidence-based recommendations to answer-specific questions considering the currently available literature. Working group members and conference attendees served as jury to edit and confirm the final recommendations presented at the end of the conference by each working group separately. This report presents the final statements and recommendations provided by working group 2, covering the entire spectrum of donor and recipient risk factors and prediction models in DCD-LT.

The impact of recipient age on the effects of umbilical cord mesenchymal stem cells on HBV-related acute-on-chronic liver failure and liver cirrhosis. Stem Cell Res Ther 2021; 12:466. [PMID: 34416908 PMCID: PMC8379867 DOI: 10.1186/s13287-021-02544-x] [Citation(s) in RCA: 12] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/07/2021] [Accepted: 08/04/2021] [Indexed: 12/22/2022] Open
Abstract
Background The results of a previous study verified that umbilical cord mesenchymal stem cells (UCMSCs) have good therapeutic effects for the treatment of HBV-related acute-on-chronic liver failure (ACLF) and liver cirrhosis (LC). Nevertheless, it is still unknown whether the effects of UCMSCs are affected by recipient age. Methods Patients treated with UCMSCs who met the criteria of HBV-related ACLF and liver cirrhosis were identified in this retrospective observational study. Patients were divided into subgroups according to the World Health Organization (WHO) age criteria (< 45 vs. ≥ 45 years). Group A included young ACLF patients (< 45 y), and group B included older ACLF patients (≥ 45 y). Young LC patients (< 45 y) were assigned to group C, and group D included older LC patients (≥ 45 y). Patients’ clinical characteristics, demographics, biochemical factors, and model for end-stage liver disease (MELD) scores were compared for 24 weeks. Results Sixty-four ACLF patients and 59 LC patients were enrolled in this study. Compared with patients in groups B and C, patients in group A did not show significant superiority in terms of the levels of ALT, AST, TBIL, AFP, and PTA and MELD scores. However, the median decrease and cumulative decrease in the TBIL and ALT levels of patients in group C were larger than those of patients in group D after four weeks of UCMSC transfusions. For older patients (≥ 45 y), the cumulative decrease and the median decrease in the TBIL of ACLF patients were significantly greater than those of LC patients after UCMSC treatment. However, the median decrease in ALT levels of ACLF patients was significantly greater than that of LC patients during UCMSC treatment, and the cumulative decrease in ALT levels of ACLF patients was significantly greater than that of LC patients at all time points. Conclusion The therapeutic effects of UCMSCs for HBV-related acute-on-chronic liver failure and liver cirrhosis varied partly by patient age. Assessing patient age is necessary prior to UCMSC clinical use. Supplementary Information The online version contains supplementary material available at 10.1186/s13287-021-02544-x.

A notable proportion of liver transplant candidates with alcohol-related cirrhosis can be delisted because of clinical improvement. J Hepatol 2021; 75:275-283. [PMID: 33746085 DOI: 10.1016/j.jhep.2021.02.033] [Citation(s) in RCA: 23] [Impact Index Per Article: 7.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/22/2020] [Revised: 02/03/2021] [Accepted: 02/24/2021] [Indexed: 01/05/2023]
Abstract
BACKGROUND & AIMS To what extent patients with alcohol-related decompensated cirrhosis can improve until recovery from decompensation remains unclear. We aimed to investigate the probability of recovery and delisting due to improvement in patients with alcohol-related decompensated cirrhosis on the waiting list (WL) for liver transplantation (LT). METHODS We conducted a registry-based, multicenter, retrospective study including all patients admitted to the LT WL in Catalonia (Spain) with the indication of alcohol-, HCV-, cholestasis- or non-alcoholic steatohepatitis-related decompensated cirrhosis between January 2007 and December 2018. Competing-risk analysis was used to investigate variables associated with delisting due to improvement in patients with alcohol-related decompensated cirrhosis. Criteria for delisting after improvement were not predefined. Outcomes of patients after delisting were also studied. RESULTS One-thousand and one patients were included, 420 (37%) with alcohol-related decompensated cirrhosis. Thirty-six (8.6%) patients with alcohol-related decompensated cirrhosis were delisted after improvement at a median time of 29 months after WL admission. Lower model for end-stage liver disease (MELD) score, higher platelets and either female sex or lower height were independently associated with delisting due to improvement, while time of abstinence did not reach statistical significance in multivariate analysis (p = 0.055). Five years after delisting, the cumulative probability of remaining free from liver-related death or LT was 76%, similar to patients with HCV-related decompensated cirrhosis delisted after improvement. CONCLUSIONS A significant proportion of LT candidates with alcohol-related cirrhosis can be delisted due to improvement, which is predicted by low MELD score and higher platelet count at WL admission. Women also have a higher probability of being delisted after improvement, partially due to reduced early access to LT for height discrepancies. Early identification of patients with potential for improvement may avoid unnecessary transplants. LAY SUMMARY Patients with alcohol-related cirrhosis can improve until being delisted in approximately 9% of cases. Low model for end-stage liver disease score and high platelet levels at admission predict delisting after improvement, and women have higher probabilities of being delisted due to improvement. Long-term outcomes after delisting are generally favorable.

Abstract
Due to increasing demand for donor organs, "extended criteria" donors are increasingly considered for liver transplantation, including elderly donors and donors after cardiac death. The grafts of this subgroup of donors share a major risk to develop significant features of ischemia reperfusion injury, that may eventually lead to graft failure. Ex-situ machine perfusion technology has gained much interest in liver transplantation, because represents both a useful tool for improving graft quality before transplantation and a platform for the delivery of therapeutics directly to the organ. In this review, we survey ongoing clinical evidences supporting the use of elderly and DCD donors in liver transplantation, and the underlying mechanistic aspects of liver aging and ischemia reperfusion injury that influence graft quality and transplant outcome. Finally, we highlight evidences in the field of new therapeutics to test in MP in the context of recent findings of basic and translational research.

Abstract
The aging process is represented by the time-dependent decay in physiologic functions of living beings. Major interest has been focused in recent years on the determinants of this progressive condition due to its correlative relationship with the onset of diseases. Several hallmark features have been observed in aging, such as genetic alterations, mitochondrial impairment, and telomere shortening. At the cellular level, a senescent phenotype has been identified in response to aging that is characterized by a flat appearance, proliferative arrest, and production of specific molecules. The net effect of these cells in the course of diseases is an argument of debate. In fact, while the onset of a senescent phenotype may prevent tumor spreading, these cells appear to support pathological processes in some conditions. Several studies are now focused on clarifying the specific molecular pathways of aging/senescence in different cells, tissues, or organs. Biliary and vascular components, within the liver, have emerged as important determinants of some form of liver disease. In this review we summarize the most recent achievements on aging/senescence, focusing on the biliary and vascular liver system. Conclusion: Several findings, in both preclinical animal models and on human liver specimens, converge in supporting the presence of specific aging hallmarks in the diseases involving these hepatic compartments.

Abstract
BACKGROUND/AIMS To analyze the incidence and risk factors of outcomes after liver transplantation (LT) in the Korean population. METHODS This study analyzed data from the liver cohort of Korean Organ Transplantation Registry (KOTRY) who had LT between May 2014 and December 2017. Study measures included the incidence of post-LT outcomes in recipients of living donor LT (LDLT) and deceased donor LT (DDLT). Cox multivariate proportional hazards model was used to determine the potential risk factors predicting the outcomes. RESULTS A total of 2,563 adult recipients with LT (LDLT, n=1,956; DDLT, n=607) were included, with mean±standard deviation age of 53.9±8.9 years, and 72.2% were male. The post-LT outcomes observed in each LDLT and DDLT recipients were death (4.0% and 14.7%), graft loss (5.0% and 16.1%), rejection (7.0% and 12.0%), renal failure (2.7% and 13.8%), new onset of diabetes (12.5% and 15.4%), and hepatocellular carcinoma (HCC) recurrence (both 6.7%). In both LDLT and DDLT recipients, the most common post-LT complications were renal dysfunction (33.6% and 51.4%), infection (26.7% and 48.4%), and surgical complication (22.5% and 23.9%). Incidence of these outcomes were generally higher among recipients of DDLT than LDLT. Multivariate analysis indicated recipient age and DDLT as significant risk factors associated with death and graft loss. DDLT and ABO incompatible transplant were prognostic factors for rejection, and HCC beyond Milan criteria at pre-transplant was a strong predictor of HCC recurrence. CONCLUSION This study is a good indicator of the post-LT prognosis in the Korean population and suggests a significant burden of post-LT complications.

Abstract
In the changing landscape of liver transplantation (LT), we are now evaluating older and sicker patients with more cardiovascular comorbidities, and the spectrum of cardiovascular disease is uniquely physiologically impacted by end-stage liver disease. Cardiac complications are now the leading cause of morbidity and mortality in LT recipients, and the pretransplant risk is exacerbated immediately during the transplant operation and continues long term under the umbrella of immunosuppression. Accurate risk estimation of cardiac complications before LT is paramount to guide allocation of limited health care resources and to improve both short-term and long-term clinical outcomes for patients. Current screening and diagnostic testing are limited in their capacity to accurately identify early coronary disease and myocardial dysfunction in persons with end-stage liver disease physiology. Furthermore, a number of testing modalities have not been evaluated in patients with end-stage liver disease. As a result, there is wide variation in cardiac risk assessment practices across transplant centers. In this review, we propose a definition for defining cardiac events in LT, evaluate the current evidence for surgery-related, short-term and long-term cardiac risk assessment in LT candidates, propose an evidence-based testing algorithm, and highlight specific gaps in knowledge and current controversies, identifying areas for future research.

[PMID: 33189566 PMCID: PMC8110600 DOI: 10.1016/j.hpb.2020.10.002] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/09/2020] [Revised: 07/20/2020] [Accepted: 10/05/2020] [Indexed: 12/12/2022]
Abstract
BACKGROUND We assessed if the risk of post-liver transplant mortality within 24 h could be stratified at the time of listing using the liver transplant risk score (LTRS). Secondary aims were to assess if the LTRS could stratify the risk of 30-day, 1-year mortality, and survival beyond the first year. METHODS MELD, BMI, age, diabetes, and the need for dialysis were the five variables used to calculate the LTRS during patients' evaluation for liver transplantation. Mortality rates at 24 h, 30 days, and 1-year were compared among groups of patients with different LTRS. Patients with ABO-incompatibility, redo, multivisceral, partial graft and malignancies except for hepatocellular carcinoma were excluded. Data of 48,616 adult liver transplant recipients were extracted from the Scientific Registry of Transplant Recipients between 2002 and 2017. RESULTS 24-h mortality was 0.9%, 1.0%, 1.1%, 1.7%, 2.3%, 2.0% and 3.5% for patients with LTRS of 0,1,2,3,4, 5 and ≥ 6, respectively (P < 0.001). 30-day mortality was 3.5%, 4.2%, 4.9%, 6.2%, 7.6%, 7.2% and 10.1% respectively (P < 0.001). 1-year mortality was 8.6%, 10.8%, 12.9%, 13.9%, 18.5%, 20.3% and 28.6% respectively (P < 0.001). 10-year survival was 61%, 56%, 57%, 54%, 47%, and 31% for patients with 0, 1, 2, 3, 4, 5 and ≥ 6 points respectively (P < 0.001). CONCLUSION Perioperative mortality and long-term survival of patients undergoing LT can be accurately estimated at the time of listing by the LTRS.

Causes of Death and Survival in Alcoholic Cirrhosis Patients Undergoing Liver Transplantation: Influence of the Patient's Clinical Variables and Transplant Outcome Complications. Diagnostics (Basel) 2021; 11:diagnostics11060968. [PMID: 34072173 PMCID: PMC8227029 DOI: 10.3390/diagnostics11060968] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/18/2021] [Revised: 05/20/2021] [Accepted: 05/24/2021] [Indexed: 11/17/2022] Open
Abstract
Background. Clinical and molecular mechanisms involved in the cause and time of death of alcoholic cirrhosis (AC) patients undergoing liver transplantation (LT) are not entirely understood. In sudden death cases, judicial autopsy practice is mandatory for determining the cause and circumstances of death. The medico-legal autopsy data are essential for helping health authorities to guide future public health activities, assess the effectiveness of health systems, and adopt the necessary preventive measures to improve and adapt the treatments in order to increase these patients’ survival. Objective. Our study aimed to determine the different clinical and sociodemographic causes that influence the different causes of death and the short- and long-term survival of AC patients undergoing liver transplantation. Methods. A total of 122 deceased AC patients undergoing LT were analyzed at different times post-transplantation. The main pre- and post-transplant complications were analyzed in relation to the cause of death and the patient’s survival, as well as the causes and time at which the patient’s death occurred. Results. A total of 53.3% of non-sudden death was observed. A large number of the deaths of AC patients undergoing transplantation were due to non-sudden death, sepsis, and graft failure (GF), the main causes of death in the sample being similar in both sexes. In non-sudden deaths, there were no significant differences between the death rates either related or not related to the liver transplant. Sepsis was the main cause, with the highest percentage (21.3%) of mortality, followed by GF (18.9%) and multiorgan failure (15.6%) at ten years. Furthermore, our results showed how pre-transplant clinical complications, such as viral infections and encephalopathy, influence the age at which multiorgan failure occurs in the transplanted patient. Conclusion. Multiorgan failure is the leading cause of sudden death, with higher mortality during the first year after transplantation, followed by sepsis and GF. Our results show the vulnerability of AC patients, both in the hospital period after the transplant and outside.

Liver Transplant Recipient, Caregiver, and Provider Perceptions of Cardiovascular Disease and Related Risk Factors After Transplant. Liver Transpl 2021; 27:668-683.

Abstract
Liver transplant recipients (LTRs) are at high risk for cardiovascular disease (CVD). We sought to characterize LTR, informal caregiver, and health care provider perceptions about CVD care after liver transplantation (LT) to inform the design of solutions to improve care. Participants included adult LTRs, their caregivers, and multispecialty health care providers recruited from an urban tertiary care network who participated in 90-minute focus groups and completed a brief survey. Focus group transcripts were analyzed using thematic analysis, and survey data were analyzed using descriptive statistics. A total of 17 LTRs, 9 caregivers, and 22 providers participated in 7 separate focus groups. Most (93.3%) LTRs and caregivers were unaware of the risk of CVD after LT. Although 54.5% of providers were confident discussing CVD risk factors with LTRs, only 36.3% were confident managing CVD risk factors in LTRs, and only 13.6% felt that CVD risk factors in their LTR patients were well controlled. Barriers to CVD care for LTRs included (1) lack of awareness of CVD risk after LT, (2) lack of confidence in an ability to provide proper CVD care to LTRs, (3) reluctance to provide CVD care without transplant provider review, and (4) complexity of communication with the multidisciplinary LTR care team about CVD care. Participant recommendations included improved education for LTRs and caregivers about CVD risk factors, electronic health record alerts for providers, clearly defined CVD care provider roles, increased use of the transplant pharmacist, and multidisciplinary provider meetings to discuss care plans for LTRs. Multiple barriers to CVD care after LT were identified, and targeted recommendations were proposed by participants. Transplant centers should integrate participants' recommendations when designing interventions to optimize CVD care for LTRs.

Abstract
BACKGROUND Prolonged stay in an intensive/high care unit (ICU/HCU) after living donor liver transplantation (LDLT) is a significant event with possible mortality. METHODS Adult-to-adult LDLTs (n = 283) were included in this study. Univariate and multivariate analyses were performed for the factors attributed to the prolonged ICU/HCU stay after LDLT. RESULTS Recipients who stayed in the ICU/HCU 9 days or longer were defined as the prolonged group. The prolonged group was older (P = .0010), had a higher model for end-stage liver disease scores (P < .0001), and had higher proportions of patients with preoperative hospitalization (P < .0001). Delirium (P < .0001), pulmonary complications (P < .0001), sepsis (P < .0001), reintubation or tracheostomy (P < .0001), relaparotomy due to bleeding (P = .0015) or other causes (P < .0001), and graft dysfunction (P < .0001) were associated with prolonged ICU/HCU stay. Only sepsis (P = .015) and graft dysfunction (P = .019) were associated with in-hospital mortality among patients with prolonged ICU/HCU stay or graft loss within 9 days of surgery. Among these patients, grafts from donors aged <42 years and with a graft-to-recipient weight ratio of >0.76% had significantly higher graft survival than grafts from others (P = .0013 and P < .0001, respectively). CONCLUSION Prolonged ICU/HCU stay after LDLT was associated with worse short-term outcomes. The use of grafts of sufficient volume from younger donors might improve graft survival.

Abstract
Despite improvements in postliver transplant outcomes through refinements in perioperative management and surgical techniques, several changing trends in liver transplantation have presented challenges. Mortality on the waitlist remains high. In the United States, Europe, and the United Kingdom, there is an increasing need for liver transplantation, primarily as a result of increased incidence of nonalcoholic steatohepatitis-related cirrhosis and cancer indications. Meanwhile, donor suitability has decreased, as donors are often older and have more comorbidities. Despite a mismatch between organ need and availability, many organs are discarded. Notwithstanding this, many solutions have been developed to overcome these challenges. Innovative techniques in allograft preservation, viability assessment, and reconditioning have allowed the use of suboptimal organs with adequate results. Refinements in surgical procedures, including live donor liver transplantations, have increased the organ pool and are decreasing the time and mortality on the waitlist. Despite many challenges, a similar number of solutions and prospects are on the horizon. This review seeks to explore the changing trends and challenges in liver transplantation and highlight possible solutions and future directions.

Abstract
Medical-refractory severe alcoholic hepatitis (AH) has a high mortality. The national frequency, longer term outcomes and regional practices of AH liver transplantation (LT) in the United States are not well described, despite the increasing mortality from alcohol-associated liver disease. We analyzed the trends in frequency and outcomes of UNOS data on 39 455 adult patients who underwent LT from 2014 to 2019, including AH LT recipients. LTs for AH increased 5-fold, from 28 in 2014 to 138 in 2019, varying 8-fold between UNOS regions. Three transplant centers accounted for 50%-90% of AH LTs within each region. The number of transplant centers performing AH LTs increased from 14 in 2014 to 47 in 2019. AH patients were younger (mean = 39.4 years), had higher MELD scores (mean = 36.8), and were more often on dialysis (46.0%) and in ICU (38.4%), compared to other indications (all P < .05). One- and 5-year graft survivals for AH LT recipients were 91.7% and 81.9%, respectively. The frequency of AH LT is increasing rapidly, with excellent medium-term outcomes. An impact of AH recurrence on patient or graft survival is not apparent in this national analysis. There are marked geographic variations in practices, highlighting the lack of selection criteria standardization.

Early Allograft Dysfunction Increases Hospital Associated Costs After Liver Transplantation-A Propensity Score-Matched Analysis. Hepatol Commun 2021; 5:526-537.

Abstract
Concepts to ameliorate the continued mismatch between demand for liver allografts and supply include the acceptance of allografts that meet extended donor criteria (ECD). ECD grafts are generally associated with an increased rate of complications such as early allograft dysfunction (EAD). The costs of liver transplantation for the health care system with respect to specific risk factors remain unclear and are subject to change. We analyzed 317 liver transplant recipients from 2013 to 2018 for outcome after liver transplantation and hospital costs in a German transplant center. In our study period, 1-year survival after transplantation was 80.1% (95% confidence interval: 75.8%-84.6%) and median hospital stay was 33 days (interquartile rage: 24), with mean hospital costs of €115,924 (SD €113,347). There was a positive correlation between costs and laboratory Model for End-Stage Liver Disease score (rs = 0.48, P < 0.001), and the development of EAD increased hospital costs by €26,229. ECD grafts were not associated with a higher risk of EAD in our cohort. When adjusting for recipient-associated risk factors such as laboratory Model for End-Stage Liver Disease score, recipient age, and split liver transplantation with propensity score matching, only EAD and cold ischemia increased total costs. Conclusion: Our data show that EAD leads to significantly higher hospital costs for liver transplantation, which are primarily attributed to recipient health status. Strategies to reduce the incidence of EAD are needed to control costs in liver transplantation.

Abstract
BACKGROUND The number of patients awaiting liver transplantation (LT) in Spain has halved from 2015 to 2019 due to the reduction of candidates with hepatitis C and the successful implementation of nonheart beating donation programs across the country. The Spanish Society for Liver Transplantation has committed to take advantage of this situation by developing consensus around potential areas to expand the current indications for LT. The consensus group was composed of 6 coordinators and 23 expert delegates, each one representing an LT institution in Spain. METHODS A modified Delphi approach was used to identify areas to expand indications for LT and to build consensus around paramount aspects, such as inclusion criteria and waitlist prioritization within each area. The scientific evidence and strength of recommendations were assessed by the "Grading of Recommendations Assessment, Development, and Evaluation" system. RESULTS The consensus process resulted in the identification of 7 potential areas to expand criteria in LT: recipient's age, hepatocellular carcinoma, alcoholic hepatitis, acute-on-chronic liver failure, hilar and intrahepatic cholangiocarcinoma, and unresectable liver metastases of colorectal cancer. CONCLUSIONS We present the main recommendations issued for each topic, together with their core supporting evidence. These recommendations may allow for expanding criteria for LT homogenously in Spain and may provide a guidance to other countries/institutions facing a similar scenario.

Abstract
Patients experience a new life with different challenges after liver transplantation (LT). Identifying these challenges can facilitate the improvement of their quality of life. This study aimed to explore patients’ experiences of post-LT life challenges. This qualitative study was performed in 2019 through the content analysis approach. Participants were liver transplant recipients purposively recruited from a LT clinic. Semistructured interviews were conducted for data collection. Data were analyzed through Graneheim and Lundman’s conventional content analysis approach. Meaning units were identified and coded, and the codes were grouped into subcategories and categories according to their similarities. In total, 18 transplant recipients were interviewed. Their age mean was 51 years and their transplant age ranged from 4 months to 12 years. Their post-LT life challenges were categorized into 4 main categories, that is, self-care deficit, the need for seeking information, fears and concerns, and hope–despair duality. Nurses and members of LT team are recommended to assess transplant recipients’ life challenges and develop comprehensive plans for managing their challenges and problems and improving their quality of life.

Abstract
Background: There are limited data on outcomes of older patients with chronic diseases. Skeletal muscle loss of aging (primary sarcopenia) has been extensively studied but the impact of secondary sarcopenia of chronic disease is not as well evaluated. Older patients with chronic diseases have both primary and secondary sarcopenia that we term compound sarcopenia. We evaluated the clinical impact of compound sarcopenia in hospitalized patients with cirrhosis given the increasing number of patients and high prevalence of sarcopenia in these patients. Design: The Nationwide Inpatients Sample (NIS) database (years 2010–2014) was analyzed to study older patients with cirrhosis. Since there is no universal hospital diagnosis code for “muscle loss”, we used a comprehensive array of codes for “muscle loss phenotype” in the international classification of diseases-9 (ICD-9). A randomly selected 2% sample of hospitalized general medical population (GMP) and inpatients with cirrhosis were stratified into 3 age groups based on age-related changes in muscle mass. In-hospital mortality, length of stay (LoS), cost of hospitalization (CoH), comorbidities and discharge disposition were analyzed. Results. Of 517,605 hospitalizations for GMP and 106,835 hospitalizations for treatment of cirrhosis or a cirrhosis-related complication, 207,266 (40.4%) GMP and 29,018 (27.7%) patients with cirrhosis were >65 years old, respectively. Muscle loss phenotype in both GMP and inpatients with cirrhosis 51–65 years old and >65 years old was significantly (p < 0.001 for all) associated with higher mortality, LoS, and CoH compared to those ≤50 years old. Patients >65 years old with cirrhosis and muscle loss phenotype had higher mortality (adjusted OR: 1.06, 95% CI [1.04, 1.08] and CoH (adjusted odds ratio (OR): 1.10, 95% confidence interval (CI) [1.04, 1.08])) when compared to >65 years old GMP with muscle loss phenotype. Muscle loss in younger patients with cirrhosis (≤50 years old) was associated with worse outcomes compared to GMP >65 years old. Non-home discharges (nursing, skilled, long-term care) were more frequent with increasing age to a greater extent in patients with cirrhosis with muscle loss phenotype for each age stratum. Conclusion: Muscle loss is more frequent in older patients with cirrhosis than younger patients with cirrhosis and older GMP. Younger patients with cirrhosis had clinical outcomes similar to those of older GMP, suggesting an accelerated senescence in cirrhosis. Compound sarcopenia in older patients with cirrhosis is associated with higher inpatient mortality, increased LoS, and CoH compared to GMP with sarcopenia.

Abstract
Increased life expectancy and advances in the care of chronic liver disease has increased the number of elderly patients needing liver transplant. Organ donation policies prioritize transplant to the sickest. There is an ongoing debate with regard to balancing the principles of equity and utility. Several hospitals have adopted center-specific policies and there has been an increased trend of transplant in elderly patients since 2002. Appropriate patient selection and long-term outcomes in the setting of limited organ availability pose several challenges. This article reviews the data and discusses the pros and cons of transplants in the elderly.

Abstract
Equity in access is one of the core goals of the Organ Procurement and Transplant Network (OPTN). However, disparities in liver transplantation have been described since the passage of the National Organ Transplant Act, which established OPTN in the 1980s. During the past few decades, several efforts have been made by the United Network for Organ Sharing (UNOS) to address disparities in liver transplantation with notable improvements in many areas. Nonetheless, disparities have persisted across insurance type, sex, race/ethnicity, geographic area, and age. African Americans have lower rates of referral to transplant centers, females have lower rates of transplantation from the liver waiting list than males, and public insurance is associated with worse posttransplant outcomes than private insurance. In addition, pediatric candidates and older adults have a disadvantage on the liver transplant waiting list, and there are widespread regional disparities in transplantation. Given the large degree of inequity in liver transplantation, there is a tremendous need for studies to propose and model policy changes that may make the liver transplant system more just and equitable.

Abstract
Hepatocellular carcinoma (HCC) is a globally prevailing cancer with a low 5-year survival rate. Little is known about its intricate gene expression profile. Single-cell RNA sequencing is an indispensable tool to explore the genetic characteristics of HCC at a more detailed level. In this study, we profiled the gene expression of single cells from human HCC tumor and para-tumor tissues using the Smart-seq 2 sequencing method. Based on differentially expressed genes, we identified heterogeneous subclones in HCC tissues, including five HCC and two hepatocyte subclones. We then carried out hub-gene co-network and functional annotations analysis followed pseudo-time analysis with regulated transcriptional factor co-networks to determine HCC cellular trajectory. We found that MLX interacting protein like (MLXIPL) was commonly upregulated in the single cells and tissues and associated with a poor survival rate in HCC. Mechanistically, MLXIPL activation is crucial for promoting cell proliferation and inhibits cell apoptosis by accelerating cell glycolysis. Taken together, our work identifies the heterogeneity of HCC subclones, and suggests MLXIPL might be a promising therapeutic target for HCC.

Outcomes of transcatheter versus surgical aortic valve replacement among solid organ transplant recipients. Catheter Cardiovasc Interv 2021; 97:691-698. [PMID: 33400380 DOI: 10.1002/ccd.29426] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/22/2020] [Revised: 11/16/2020] [Accepted: 11/29/2020] [Indexed: 11/09/2022]
Abstract
BACKGROUND There is a paucity of data regarding the outcomes of transcatheter aortic valve replacement (TAVR) versus surgical aortic valve replacement (SAVR) among solid-organ transplant recipients. METHODS Temporal trends in hospitalizations for aortic valve replacement among solid-organ transplant recipients were determined using the National Inpatient Sample database years 2012-2017. Propensity matching was conducted to compare admissions who underwent TAVR versus SAVR. The primary outcome was in-hospital mortality. RESULTS The analysis included 1,730 hospitalizations for isolated AVR; 920 (53.2%) underwent TAVR and 810 (46.7%) underwent SAVR. TAVR was increasingly utilized for solid-organ transplant recipients (Ptrend = 0.01), while there was no change in the number of SAVR procedures (Ptrend = 0.20). The predictors of undergoing TAVR for solid-organ transplant recipients included older age, diabetes, and prior coronary artery bypass surgery, while TAVR was less likely utilized in small-sized hospitals. TAVR was associated with lower in-hospital mortality after matching (0.9 vs. 4.7%, odds ratio [OR] 0.19; 95% confidence interval [CI] 0.11-0.35, p < .001) and after multivariable adjustment (OR 0.07; 95% CI 0.03-0.21, p < .001). TAVR was associated with lower rate of acute kidney injury, acute stroke, postoperative bleeding, blood transfusion, vascular complications, discharge to nursing facilities, and shorter median length of hospital stay. There was no difference between both groups in the use of mechanical circulatory support, hemodialysis, arrhythmias, or pacemaker insertion. CONCLUSION This contemporary observational nationwide analysis showed that TAVR is increasingly performed among solid-organ transplant recipients. Compared with SAVR, TAVR was associated with lower in-hospital mortality, complications, and shorter length of stay.

Contrast-enhanced ultrasonography to evaluate risk factors for short-term and long-term outcomes after liver transplantation: A pilot prospective study. Eur J Radiol 2020; 135:109475. [PMID: 33373895 DOI: 10.1016/j.ejrad.2020.109475] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/13/2020] [Revised: 11/16/2020] [Accepted: 12/07/2020] [Indexed: 02/07/2023]
Abstract
PURPOSE To evaluate whether Doppler ultrasonography (DUS) and contrast-enhanced ultrasonography (CEUS) can identify liver donation after brain death (DBD) and cardiac death (DCD) with the risk of developing short-term primary graft dysfunction (PGD) or arterial and biliary complications within 1 year. MATERIALS AND METHODS Consecutive DBD and DCD donors who underwent DUS/CEUS examinations before surgical procurement from February 2016 to June 2018 at our institution were included. The US and CEUS images of each donor liver were analysed, and the parameters were recorded. RESULTS The mean time for US examination was 32 min (range, 20-59 min), and all donors tolerated the examination well. In terms of short-term outcomes, among the 52 eligible donor livers, 20 (38.5 %) of their recipients developed PGD. The multivariable analysis showed that decreased enhancement of donor livers on CEUS (OR = 15.976, 95 % CI: 1.652-154.628, P = 0.017) and high recipient model for end-stage liver disease (MELD) scores (OR = 1.050, 95 % CI: 1.004-1.099, P = 0.034) before liver transplantation (LT) were independent factors of PGD. In contrast, for long-term complications, among the 48 eligible donor livers, 16 (33.3 %) developed arterial or biliary complications within 1 year. The multivariable analysis did not show any independent factors of arterial or biliary complications within 1 year. CONCLUSIONS A decrease in enhancement on CEUS is an independent risk factor for poor short-term outcomes of LT. CEUS may be promising for predicting post-LT outcomes of critically ill donors effectively and safely by evaluating the haemodynamic changes in DBD and DCD donor livers.
