Abstract
Liver transplantation indications continue to evolve in North America. Several recent changes have occurred in the field with changes in the allocation system, new performance metrics, expansion of transplant oncology, and utilization of ex vivo perfusion devices and techniques. Deceased donor liver transplantation continues to be the primary modality of liver transplantation in North America, with an ongoing focus on advancing the use of living donor liver transplantation, especially in those patients who may not have favorable access to deceased donor allografts.

Abstract
BACKGROUND The shortage of liver grafts and subsequent waitlist mortality led us to expand the donor pool using liver grafts from older donors. AIM To determine the incidence, outcomes, and risk factors for biliary complications (BC) in liver transplantation (LT) using liver grafts from donors aged > 70 years. METHODS Between January 1994 and December 31, 2019, 297 LTs were performed using donors older than 70 years. After excluding 47 LT for several reasons, we divided 250 LTs into two groups, namely post-LT BC (n = 21) and without BC (n = 229). This retrospective case-control study compared both groups. RESULTS Choledocho-choledochostomy without T-tube was the most frequent technique (76.2% in the BC group vs 92.6% in the non-BC group). Twenty-one patients (8.4%) developed BC (13 anastomotic strictures, 7 biliary leakages, and 1 non-anastomotic biliary stricture). Nine patients underwent percutaneous balloon dilation and nine required a Roux-en-Y hepaticojejunostomy because of dilation failure. The incidence of post-LT complications (graft dysfunction, rejection, renal failure, and non-BC reoperations) was similar in both groups. There were no significant differences in the patient and graft survival between the groups. Moreover, only three deaths were attributed to BC. While female donors were protective factors for BC, donor cardiac arrest was a risk factor. CONCLUSION The incidence of BC was relatively low on using liver grafts > 70 years. It could be managed in most cases by percutaneous dilation or Roux-en-Y hepaticojejunostomy, without significant differences in the patient or graft survival between the groups.

Abstract
BACKGROUND AND AIMS Liver transplantation (LT) is the treatment of end-stage non-alcoholic liver disease (NAFLD), that is decompensated cirrhosis and/or complicated by hepatocellular carcinoma (HCC). Few data on long-term outcome are available. The aim of this study was to evaluate overall patient and graft survivals and associated predictive factors. METHOD This retrospective multicentre study included adult transplant patients for NAFLD cirrhosis between 2000 and 2019 in participating French-speaking centres. RESULTS A total of 361 patients (69.8% of male) were included in 20 centres. The median age at LT was 62.3 years [57.4-65.9] and the median MELD score was 13.9 [9.1-21.3]; 51.8% of patients had HCC on liver explant. Between 2004 and 2018, the number of LT for NAFLD cirrhosis increased by 720%. A quarter of the patients had cardiovascular history before LT. Median follow-up after LT was 39.1 months [15.8-72.3]. Patient survival at 1, 5 and 10 years after LT was 89.3%, 79.8% and 68.1% respectively. The main causes of death were sepsis (37.5%), malignancies (29.2%) and cardiovascular events (22.2%). In multivariate analysis, three risk factors for overall mortality after LT were recipient pre-LT BMI < 32 kg/m2 at LT time (OR: 2.272; p = .012), pre-LT angioplasty during CV check-up (OR: 2.916; p = .016), a combined donor and recipient age over 135 years (OR: 2.020; 95%CI: p = .035). CONCLUSION Survival after LT for NAFLD cirrhosis is good at 5 years. Donor and recipient age, and cardiovascular history, are major prognostic factors to consider.

Abstract
INTRODUCTION Hepatitis C virus (HCV) may recur after liver transplantation (LT) in the severe form of fibrosing cholestatic hepatitis (FCH). The prognosis dramatically improved by the use of direct acting antivirals (DAAs). The aim of the present study was to describe the change in histological features of FCH after virological eradication. METHODS From the ANRS CUPILT cohort we included 17 patients who presented FCH and at least two graft biopsies, one before DAA-treatment and one after. A single expert pathologist, blinded for clinical outcome, retrospectively confirmed the diagnosis of FCH and progression of fibrosis. RESULTS Diagnosis of FCH was made after a median [IQR] 6.0 [3.1-11.8] months after LT, and the median interval between diagnosis and onset of treatment was 1.2 [0.7-6.1] months. The rate of viral eradication was 94.1%. The median delay between the pre-treatment and the treatment biopsies was 12.5 [11.1-20.0] months. Between the end of treatment and the second biopsy, the delay was 5.3 [0.6-7.4] months. Fibrosis stage worsened in 10 patients (58.8%); 6 patients had cirrhosis (35.3%). Chronic rejection appeared in 4 (23.5%) patients. CONCLUSION Our results suggest that, despite viral eradication in patients presenting FCH after LT, fibrosis progression was observed in half of patients. This should encourage monitoring fibrosis progression despite HCV cure.

Utilization of elderly donors in liver transplantation for patients with hepatocellular carcinoma: A national retrospective cohort study of China. Int J Surg 2022; 105:106839. [PMID: 35987333 DOI: 10.1016/j.ijsu.2022.106839] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/15/2022] [Revised: 08/07/2022] [Accepted: 08/11/2022] [Indexed: 11/22/2022]
Abstract
BACKGROUND Profound organ shortages worldwide have led to the increased utilization of marginal organs from older individuals. However, the effectiveness of liver transplantation (LT) with organs from elderly donors for patients with hepatocellular carcinoma (HCC) remains controversial. The objective of the current study was to assess the overall survival (OS) and disease-free survival (DFS) of patients with HCC following LT using grafts from deceased donors over 60 years old. MATERIAL AND METHODS Patients with HCC who underwent LT between 2015 and 2018 were identified in the China Liver Transplant Registry database. The overall survival and disease-free survival of older liver donors (OLDs) were compared with those of younger liver donors (YLDs) after propensity score matching. RESULTS From January 2015 to December 2018, a total of 4971 HCC patients were enrolled in the study according to the screening criteria. The absolute and relative utilization of liver grafts from elderly patients over 60 years for HCC patients increased every year, from 65 (9.3%) in 2015 to 268 (14.5%) in 2018. Disease-free survival (DFS) was significantly lower in HCC patients with elderly donors (both P < 0.05) after propensity score matching. The OLD group had worse DFS than YLD group if patients had tumors beyond the Milan criteria (P < 0.05). CONCLUSIONS The use of older donors for LT has been growing quickly in the last few years in China. Grafts from older donors can be safely used in HCC recipients with similar OS and comparable perioperative complications. However, further investigation into whether older donor has an impact on recurrence is warranted, especially among those with tumors beyond the Milan criteria.

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 correct timing of use of direct acting agents (DAAs) among transplanted patients remains unknown. The aim of this paperwork is to evaluate the impact of DAAs treatment in pre- or peri-operative period in liver transplantation when grafts ≥ 70 years are used. This is a retrospective analysis comparing adult liver transplant performed for HCV-related cirrhosis and/or hepatocarcinoma using a graft ≥ 70 in the period 2015-2018 (Group DAA-HCV-OLD, study group) to three different groups: (a) anti-HCV-Ab-negative patients receiving graft ≥ 70 (no-HCV-OLD), (b) anti-HCV-Ab-negative patients receiving a graft aged 18-69 years (no-HCV-YOUNG), and (c) anti-HCV-Ab-positive patients receiving a donor graft ≥ 70 in the period 2007-2011 (no-DAA-HCV-OLD). Totally, 528 liver transplants were considered: 164 in DAA-HCV-OLD, 143 in no-HCV-OLD, 120 in no-HCV-YOUNG and 101 in no-DAA-HCV-OLD Group. Graft survival rates at 1 and 3 years were 88% and 81% in DAA-HCV-OLD Group, 82% and 68% in no-DAA-HCV-OLD (p = 0.007), 89% and 84% in no-HCV-OLD (p = 0.76), and 94% and 92% in no-HCV-YOUNG (p = 0.02). No differences were observed among groups in the incidence of primary non-function, primary dysfunction, vascular or biliary complications. DAAs were able to zero HCV-related graft loss, with a 3-year graft survival > 80%. The outcomes of older graft recipients became equal irrespectively of their HCV serological status.

Safe use of livers from deceased donors older than 70 years in recipients with HCV cirrhosis treated with direct-action antivirals. Retrospective cohort study. Int J Surg 2021; 91:105981.

Abstract
INTRODUCTION There is controversy regarding the use of older grafts for liver transplantation (LT) in HCV-infected patients, but the introduction of direct-acting antivirals (DAA) can radically change that debate. METHODS The aim of this retrospective cohort study was to evaluate outcomes of the use of liver grafts from donors older than 70 years in recipients with HCV infection who underwent pre- or post-LT treatment with DAA. We compared two groups of patients who underwent LT using livers >70 years; the groups were defined according to antiviral therapy: non-DAA therapy group (n = 62; LT between May 1996 and December 2013), and DAA therapy group (n = 31; LT between January 2014 and December 2019). RESULTS Thirty (96.8%) patients of DAA therapy and nine (14.5%) of non-DAA therapy (21 patients underwent complete therapy with interferon-ribavirin) achieved sustained viral response (SVR). One, 3-, and 5-year patient survival were 83.9%, 67.7%, and 56.5% in the non-DAA group vs 93.5%, 88.4%, and 88.4% in the DAA group (P = 0.04); the 1-, 3-, and 5-year graft survival were 77.4%, 62.9%, and 51.6% in the non-DAA group vs. 88.6%, 83.7%, and 83.7% in the DAA group (P = 0.03). Multivariate analysis demonstrated donor female sex and DAA therapy as protective factors of graft survival. CONCLUSIONS Pre- or post-LT therapy with DAA in HCV-infected patients has achieved an almost overall SVR. The use of liver grafts >70 years in these patients treated with DAA was associated with significantly higher 5-year patient and graft survival in DAA group compared to non-DAA group. Thus, the introduction of DAA therapy has allowed the safe use of livers >70 years in HCV-positive recipients.

HPB (Oxford) 2021; 23:927-936. [PMID: 33189566 PMCID: PMC8110600 DOI: 10.1016/j.hpb.2020.10.002] [Citation(s) in RCA: 0] [Impact Index Per Article: 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.

Abstract
OBJECTIVES We investigated clinical characteristics and demographics of brain death in patients from a single center in Korea to identify possible changes in organ procurement by comparing early and late periods. MATERIALS AND METHODS Potential donors diagnosed as brain dead and who had provided organ donation consent from May 2000 to May 2020 were considered. Donors were divided into 2 categories: early period (2000-2010) and late period (2011-2020).Demographic data, clinicalrisk factors, cause of death, use ofinotropic and vasoconstrictor agents, laboratory findings, intensive care unit stay data, loss of donors, and number of donated organs were analyzed. RESULTS Mean age of donors significantly increased in the late period (36.0 ± 12.0 vs 46.0 ± 15.1 years), but there were no significant differences in the proportion of females and the number of pediatric donors (<18 years). The number of donors who smoked decreased (61% vs 41%), but hypertension rate increased significantly in the late period (17.4% vs 31.0%). In the late period, fewer brain dead donors were lost (19.0% vs 7.59%) and use of vasoconstrictor agents was more frequent (25.3% vs 64.5%) than use of inotropic agents (73.1% vs 49.3%). In the late period, heart(19.0% vs 37.3%) and lung (0% vs 18.3%) procurement rates increased and the number of transplanted organs per donorincreased (2.58 ± 1.6 vs 3.14 ± 1.50; P = .016). Causes of death were primarily from head traumas (34.4%), cerebral aneurysms (21.7%), spontaneous intracerebral hemorrhage (21.3%), and asphyxia/hanging (16.3%). Head trauma decreased in the late period (46% vs 29.7%; P = .021) but still constituted the most common cause of death. CONCLUSIONS We found no definite demographic changes in brain dead donors. Donors with cerebrovascular disease increased annually, but trauma was still the most common cause of brain death, with suicides being highly frequent.

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
The success of direct-acting antiviral (DAA) therapy has led to near-universal cure for patients chronically infected with hepatitis C virus (HCV) and improved post-liver transplant (LT) outcomes. We investigated the trends and outcomes of retransplantation in HCV and non-HCV patients before and after the introduction of DAA. Adult patients who underwent re-LT were identified in the Organ Procurement and Transplantation Network/United Network for Organ Sharing database. Multiorgan transplants and patients with >2 total LTs were excluded. Two eras were defined: pre-DAA (2009-2012) and post-DAA (2014-2017). A total of 2112 re-LT patients were eligible (HCV: n = 499 pre-DAA and n = 322 post-DAA; non-HCV: n = 547 pre-DAA and n = 744 post-DAA). HCV patients had both improved graft and patient survival after re-LT in the post-DAA era. One-year graft survival was 69.8% pre-DAA and 83.8% post-DAA (P < .001). One-year patient survival was 73.1% pre-DAA and 86.2% post-DAA (P < .001). Graft and patient survival was similar between eras for non-HCV patients. When adjusted, the post-DAA era represented an independent positive predictive factor for graft and patient survival (hazard ratio [HR]: 0.67; P = .005, and HR: 0.65; P = .004) only in HCV patients. The positive post-DAA era effect was observed only in HCV patients with first graft loss due to disease recurrence (HR: 0.31; P = .002, HR 0.32; P = .003, respectively). Among HCV patients, receiving a re-LT in the post-DAA era was associated with improved patient and graft survival.

Abstract
BACKGROUND The liver transplant risk score (LTRS) was developed to stratify 90-day mortality of patients referred for liver transplantation (LT). We aimed to validate the LTRS using a new cohort of patients. METHODS The LTRS stratifies the risk of 90-day mortality of LT recipients based on their age, body mass index, diabetes, model for end-stage liver disease (MELD) score, and need for dialysis. We assessed the performance of the LTRS using a new cohort of patients transplanted in the United States between July 2013 and June 2017. Exclusion criteria were age <18 years, ABO incompatibility, redo or multivisceral transplants, partial grafts, malignancies other than hepatocellular carcinoma and fulminant hepatitis. RESULTS We found a linear correlation between the number of points of the LTRS and 90-day mortality. Among 18 635 recipients, 90-day mortality was 2.7%, 3.8%, 5.2%, 4.8%, 6.7%, and 9.3% for recipients with 0, 1, 2, 3, 4, and ≥5 points (P < 0.001). The LTRS also stratified 1-year mortality that was 5.5%, 7.7%, 9.9%, 9.3%, 10.8%, and 15.4% for 0, 1, 2, 3, 4, and ≥5 points (P < 0.001). An inverse correlation was found between the LTRS and 4-year survival that was 82%, 79%, 78%, 82%, 78%, and 66% for patients with 0, 1, 2, 3, 4, and ≥5 points (P < 0.001). The LTRS remained an independent predictor after accounting for recipient sex, ethnicity, cause of liver disease, donor age, cold ischemia time, and waiting time. CONCLUSIONS The LTRS can stratify the short- and long-term outcomes of LT recipients at the time of their evaluations irrespective of their gender, ethnicity, and primary cause of liver disease.

Abstract
Despite record-breaking numbers of liver transplants (LTs) performed in the United States in each of the last 7 years, many patients remain on the wait list as the demand for LT continues to exceed the supply of available donors. The emergence of highly effective and well-tolerated direct-acting antiviral therapy has transformed the clinical course and management of hepatitis C virus (HCV) in both the pretransplant and posttransplant setting. Historically, donor livers infected with HCV were either transplanted into patients already infected with HCV or discarded.

An observational study on the effect of hypercholesterolemia developed after living donor liver transplantation on cardiac event and graft failure. Sci Rep 2021; 11:959.

Abstract
This study sought to evaluate the association between newly-developed significant hypercholesterolemia within one year following living donor liver transplantation (LDLT) and long term outcomes in light of cardiovascular events and graft failure. From October 2003 to July 2017, 877 LDLT recipients were stratified according to development of significant hypercholesterolemia within one year following LDLT. The primary outcome was occurrence of a major adverse cardiac event (MACE), defined as a composite of cardiac death, myocardial infarction, and coronary revascularization after LDLT. The incidence of graft failure, defined as all-cause death or retransplantation, was also compared. A total of 113 (12.9%) recipients developed significant hypercholesterolemia within one year. The differences in incidences of cardiac related events and graft related events began emerging significantly higher in the hypercholesterolemia group after 24 months and 60 months since the LDLT, respectively. After adjustment using the inverse probability of weighting, the hazard ratio (HR) for MACE was 2.77 (95% confidence interval (CI) 1.16–6.61; p = 0.02), while that for graft failure was 3.76 (95% CI 1.97–7.17, p < 0.001). A significant hypercholesterolemia after LDLT may be associated with cardiac and graft-related outcome; therefore, a further study and close monitoring of cholesterol level after LDLT is needed.

Abstract
BACKGROUND Despite steadily increasing donor age, there are no general guidelines for the use of organs from elderly donors in liver transplantation. This study focuses on identifying the recipients who are less affected from an old-donor organ graft and conversely in whom a rather unfavorable outcome is expected because of high donor age. METHODS Forty-eight thousand two hundred sixty-one adult liver transplantations, performed between 2000 and 2017 and reported to the Collaborative Transplant Study, were analyzed. RESULTS The proportion of ≥65-year-old donors has risen to >33% in recent years. The donor age has an approximately linear influence on graft survival. On average, each year's rise in the donor age was associated with a 0.9% increase in the risk of graft loss (hazard ratio [HR], 1.009; P < 0.001). The impact of donor age was strong in patients with hepatitis C-related cirrhosis (HR, 1.013; P < 0.001), substantial in patients with alcoholic cirrhosis (HR, 1.007; P < 0.001) and rather weak in patients with hepatocellular carcinoma (HR, 1.003; P = 0.038). The increase in the risk of graft loss per year rise in donor age was 1.4% for 18 to 49 year olds, 1.0% for middle-aged, and only 0.4% for ≥60-year-old recipients (all P < 0.001). CONCLUSIONS Consequently, older recipients and especially patients with hepatocellular carcinoma seem to be less affected by an increased donor age, whereas the donor age is an important factor in all other patient groups.

Increased Surgical Complications but Improved Overall Survival with Adult Living Donor Compared to Deceased Donor Liver Transplantation: A Systematic Review and Meta-Analysis. BIOMED RESEARCH INTERNATIONAL 2020; 2020:1320830.

Abstract
Background Living donor liver transplantation (LDLT) provides an alternative to deceased donor liver transplantation (DDLT) for patients with end-stage liver disease in the circumstance of scarcity of deceased grafts. However, the outcomes of LDLT remain controversial. Method A systematic review and meta-analysis were performed to compare the outcomes of LDLT with DDLT. Twelve outcomes were assessed. Results Thirty-nine studies involving 38563 patients were included. LDLT was comparable in red blood cell transfusion, perioperative mortality, length of hospital stay, retransplantation rate, hepatitis C virus recurrence rate, and hepatocellular carcinoma recurrence rate with DDLT. Cold ischemia time was shorter and duration of recipient operation was longer in LDLT. Postoperative intra-abdominal bleeding rate occurred less frequently in LDLT recipients (odds ratio (OR) = 0.64, 95%confidence interval (CI) = 0.46 − 0.88, P = 0.006), but this did not decrease the perioperative mortality. LDLT was associated with significantly higher biliary (OR = 2.23, 95%CI = 1.59 − 3.13, P < 0.00001) and vascular (OR = 2.00, 95%CI = 1.31 − 3.07, P = 0.001) complication rates and better overall survival (OS) (1 year: OR = 1.32, 95%CI = 1.01 − 1.72, P = 0.04; 3 years: OR = 1.39, 95%CI = 1.14 − 1.69, P = 0.0010; and 5 years: OR = 1.33, 95%CI = 1.04 − 1.70, P = 0.02). According to subgroup analysis, biliary complication rate and OS improved dramatically as experience increased, while vascular complication rate could not be improved because it was mainly caused by the difference of the donor type itself. Conclusions LDLT remains a valuable option for patients in need of liver transplantation for it provides an excellent alternative to DDLT without compromising recipient outcomes. Further refinement in biliary and vascular reconstruction techniques and the accumulation of liver transplantation centers' experience are the key factors in expanding the application of LDLT.

Abstract
The aging process causes detrimental changes in a variety of organ systems. These changes include: lesser ability to cope with stress, impaired repair mechanisms and decreased cellular functional reserve capacity. Not surprisingly, aging has been associated with increased susceptibility of donor heart and kidneys grafts to ischemia reperfusion injury (IRI). In the context of liver transplantation, however, the effect of donor age seems to be less influential in predisposing the graft to IRI. In fact, a widely comprehensive understanding of IRI in the aged liver has yet to be agreed upon in the literature. Nevertheless, there have been many reported implications of increased liver donor age with poor clinical outcomes besides IRI. These other poor outcomes include: earlier HCV recurrence, increased rates of acute rejection and greater resistance to tolerance induction. While these other correlations have been identified, it is important to re-emphasize the fact that a unified consensus in regard to liver donor age and IRI has not yet been reached among researchers in this field. Many researchers have even demonstrated that the extent of IRI in aged livers can be ameliorated by careful donor selection, strict allocation or novel therapeutic modalities to decrease IRI. Thus, the goals of this review paper are twofold: 1) To delineate and summarize the conflicting data in regard to liver donor age and IRI. 2) Suggest that careful donor selection, appropriate allocation and strategic effort to minimize IRI can reduce the frequency of a variety of poor outcomes with aged liver donations.

Abstract
BACKGROUND AND AIM Body composition has emerged as a prognostic factor for end-stage liver disease. We therefore investigated muscle mass, body fat and other clinical-pathological variables as predictors of posttransplant survival. METHODS A total of 368 patients, who underwent orthotopic liver transplantation (OLT) at our institution, were assessed prior to OLT and followed for a median of 9.0 years (range 2.0-10.0 years) after OLT. Psoas, erector spinae and the combined paraspinal muscle area, as well as the corresponding indices normalized by body-height squared, were quantified by a lumbar (L3) cross-sectional computed tomography. In addition, absolute body fat and bone density were estimated by the same computed tomography approach. RESULTS Paraspinal muscle index (PSMI) (hazard ratio 0.955, P = 0.039) and hepatitis C (hazard rati 1.498, P = 0.038) were independently associated with post-OLT mortality. In contrast, body fat and bone density did not significantly affect post-OLT outcome (P > 0.05). The PSMI also predicted one-year posttransplant mortality with a receiver operating characteristics-area under the curve of 0.671 [95% confidence interval (CI) 0.589-0.753, P < 0.001) in male patients and outperformed individual psoas and erector spinae muscle group assessments in this regard. In male patients, a defined PSMI cutoff (<18.41 cm/m) was identified as suitable determinant for sarcopenia and posttransplant one-year mortality. In female OLT-recipients, however, sarcopenia was not predictive for patient survival und a women-specific cutoff could not be derived from this study. CONCLUSIONS Taken together this analysis provides evidence, which PSMI is a relevant marker for muscle mass and that sarcopenia is an independent predictor of early post-OLT survival in male patients.

Abstract
Liver transplantation is the main curative therapy for end-stage liver disease. The number of transplanted organs is increasing globally. However, the number of available organs in the pool is insufficient, considering the excessive number of patients on the waiting list, which is a major concern for transplant programs. Hepatitis C infection (HCV) is a common indication for liver transplantation, and in recent years, a major progress has been made in its treatment with direct-acting antiviral (DAA) agents. HCV-positive livers have been transplanted to HCV-positive recipients for a long time. The high rate of sustained virologic response through DAA has brought new treatment options for the patients during the pre- and post-transplantation periods. Recently, there have been few reports of transplanting the available HCV-positive organs to HCV noninfected recipients. However, there is not yet an agreement on the optimal selection of patients who would benefit from such transplantation, and this has become a current topic of interest. Thus, we aim to review the current literature on this evolving topic.

Abstract
OBJECTIVE To investigate trends in long-term graft and patient outcomes following liver transplantation using grafts from donors ≥60 years old. SUMMARY BACKGROUND DATA The scarcity of donor livers has led to increased utilization of organs from donors ≥60 years old. However, few studies have examined how long-term transplant outcomes from older donors have evolved over time. METHODS The OPTN/UNOS database was queried for all first-time isolated adult liver transplants. We identified 14,796 adult liver transplant using donors ≧60-year-old suitable for analysis from 1990 to 2014. Cohorts were then developed based on 5-year intervals of transplant date. Kaplan-Meier analysis was used to compare graft and patient survival for recipients from older donor across each 5-year era. RESULTS Utilization of donor grafts ≥60 years old increased steadily for the first 15 years of the study, but has leveled off over the last 10 years. Comparison of the earliest and latest eras in the study was notable for an increase in median recipient age (51 vs. 59, P < 0.001) and reduction in median cold ischemic time (10 vs. 6 h, P = 0.001). Unadjusted 5-year graft and patient survival has improved significantly over time (P < 0.0001). More importantly, the discrepancy in survival between older and younger grafts has narrowed substantially over time (P < 0.0001). CONCLUSIONS This study demonstrates significant improvement in transplant outcomes with donor grafts ≥60-years old and supports increased but judicious use of extended criteria donors liver grafts. Improved patient selection and reduction in cold ischemia time appear to be contributing factors.

Abstract
OBJECTIVE To evaluate the use of elderly donors in liver transplantation (LT) and identify risk factors associated with a worse outcome. SUMMARY BACKGROUND DATA Use of livers from very old donors could expand the donor pool but is not universally implemented. METHODS This is a retrospective, single-center medical record review. From January 2001 to December 2014, 1354 LTs were performed. After exclusion of donors <18 years, ABO-incompatible LT, re-LT and UNOS 1 status patients, LT recipients were stratified into 2 groups based on donor age: 18-69 (n=692) vs. ≥70 years (n=515) then matched using a propensity score approach. Two groups were finally matched (young group = 448 cases; old group = 515 cases). RESULTS The median (interquartile range [IQR]) follow-up was 5.0 (2.0-8.4) years. Comparing the 2 identified groups, no differences were observed regarding early retransplants (1.8 vs. 2.9; P = 0.3), HCV-related death (7.6 vs. 8.7%; P = 0.6), vascular (5.8 vs. 5.0%; P = 0.7), and biliary complications (16.5 vs. 18.6%; P = 0.4). On multivariate analysis, independent risk factors for graft loss were: HCV-positive recipient (HR = 2.1; 95% CI = 1.6-2.7; P < 0.001), donor age (HR = 1.0; 95% CI = 1.0-1.0; P < 0.001), cold ischemia time (HR = 1.0; 95% CI = 1.0-1.0; P = 0.042), and donor history of diabetes mellitus (HR = 1.48; 95% CI = 1.03-2.13; P = 0.036). CONCLUSIONS Use of elderly donors is not associated per se with an increased risk of vascular and biliary complications. In the presence of cold ischemia time and diabetes mellitus, appropriate donor-to-recipient matching is warranted.

Impact of Donor Age on Recipient Survival in Adult-to-Adult Living-donor Liver Transplantation. Ann Surg 2019; 267:1126-1133.

Abstract
OBJECTIVE To investigate the influence of donor age on recipient outcome after living-donor partial liver transplantation (LDLT). BACKGROUND Donor age is a well-known prognostic factor in deceased donor liver transplantation; however, its role in LDLT remains unclear. METHODS We retrospectively analyzed 315 consecutive cases of primary adult-to-adult LDLT in our center between April 2006 and March 2014. Recipients were divided into 5 groups according to the donor age: D-20s (n = 60); D-30s (n = 72); D-40s (n = 57); D-50s (n = 94); and D-60s (n = 32). The recipient survival and the association with various clinical factors were investigated. RESULTS Recipient survival proportions were significantly higher in D-20s compared with all the other groups (P = 0.008, < 0.001, < 0.001, and = 0.006, vs D-30s, -40s, -50s, and -60s, respectively), whereas there was no association between recipient survival and their own age. There are 3 typical relationships between donors and recipients in adult-to-adult LDLT: from child-to-parent, between spouses/siblings, and from parent-to-child. The overall survival in child-to-parent was significantly higher than in spouses/siblings (P = 0.002) and in parent-to-child (P = 0.005), despite significantly higher recipient age in child-to-parent [59 (42-69) years, P < 0.001]. Contrastingly, parent-to-child exhibited the lowest survival, despite the youngest recipient age [26 (20-43) years, P < 0.001]. In addition, younger donor age exhibited significantly better recipient survival both in hepatitis C virus-related and in non-hepatitis C virus diseases. Univariate and multivariate analyses both demonstrated that donor age and graft-type (right-sided livers) are independent prognostic factors for recipient survival. CONCLUSIONS Donor age is an independent, strong prognostic factor in adult-to-adult LDLT.

Abstract
BACKGROUND Immune response failure against hepatitis C virus (HCV) has been associated with an increased regulatory T cell (Treg) activity. After liver transplantation (LT), 80% of patients experience an accelerated progression of hepatitis C recurrence. The aim of this work was to assess the involvement of Tregs, T helper (Th) 1, 2 and 17 cells in recurrent hepatitis C. METHODS Peripheral blood cells obtained before and one month after LT from 22 recipients were analysed. Forty-four key molecules related to Treg, Th1, 2 and 17 responses, were evaluated using qRT-PCR. Liver recipients were classified in two groups according to graft fibrosis evaluated by the METAVIR score on the biopsy performed one year after LT (mild: F ≤ 1, n = 13; severe: F > 1, n = 9). Patients developing a severe recurrence were compared with patients with a mild recurrence. RESULTS mRNA levels of Treg markers obtained one month after LT were significantly increased in patients with a severe disease course when compared to patients with a mild recurrence. Markers of the Th1 response were elevated in the same group. No differences in the markers determined before LT were observed. CONCLUSION These findings suggest that Treg, induced by a multifactorial process, which could include a strong Th1 response itself, may play a role in suppressing the early antiviral response, leading to a severe recurrence of hepatitis C.

Abstract
The average age of liver transplant donors and recipients has increased over the years. Independent of the cause of liver disease, older candidates have more comorbidities, higher waitlist mortality and higher post-transplant mortality than younger patients. However, transplant benefit may be similar in older and younger recipients, provided older recipients are carefully selected. The cohort of elderly patients transplanted decades ago is also increasingly raising issues concerning long-term exposure to immunosuppression and aging of the transplanted liver. Excellent results can be achieved with elderly donors and there is virtually no upper age limit for donors after brain death liver transplantation. The issue is how to optimise selection, procurement and matching to ensure good results with elderly donors. The impact of old donor age is more pronounced in younger recipients and patients with a high model for end-stage liver disease score. Age matching between the donor and the recipient should be incorporated into allocation policies with a multistep approach. However, age matching may vary depending on the objectives of different allocation policies. In addition, age matching must be revisited in the era of direct-acting antivirals. More restrictive limits have been adopted in donation after circulatory death. Perfusion machines which are currently under investigation may help expand these limits. In living donor liver transplantation, donor age limit is essentially guided by morbidity related to procurement. In this review we summarise changing trends in recipient and donor age. We discuss the implications of older age donors and recipients. We also consider different options for age matching in liver transplantation that could improve outcomes.

Abstract
BACKGROUND & AIMS Guidelines do not recommend transplanting hepatitis C virus (HCV)-infected livers into HCV-uninfected recipients. Direct-acting antivirals (DAAs) can be used to treat donor-derived HCV infection. However, the added cost of DAA therapy is a barrier. We evaluated the cost effectiveness of transplanting HCV-positive livers into HCV-negative patients with preemptive DAA therapy. METHODS A previously validated Markov-based mathematical model was adapted to simulate a virtual trial of HCV-negative patients on the liver transplant waitlist. The model compared long-term clinical and economic outcomes in patients willing to accept only HCV-negative livers vs those willing to accept any liver (HCV negative or HCV positive). Recipients of HCV-positive livers received 12 weeks of preemptive DAA therapy. The model incorporated data from the United Network for Organ Sharing and published sources. RESULTS For patients with a model for end-stage liver disease (MELD) score ≥ 22, accepting any liver vs waiting for only HCV-negative livers was cost effective, with incremental cost-effectiveness ratios ranging from $56,100 to $91,700/quality-adjusted life-year. For patients with a MELD score of 28 (the median MELD score of patients undergoing transplantation in the United States), accepting any liver was cost effective at an incremental cost-effectiveness ratio of $62,600/quality-adjusted life year. In patients with low MELD scores, which may not accurately reflect disease severity, accepting any liver was cost effective, irrespective of MELD score. CONCLUSIONS Using a Markov-based mathematical model, we found transplanting HCV-positive livers into HCV-negative patients with preemptive DAA therapy to be a cost-effective strategy that could improve health outcomes.

World J Gastroenterol 2018; 24:5525-5536.

Abstract
BACKGROUND Given the shortage of suitable liver grafts for liver transplantation, proper use of hepatitis B core antibody-positive livers might be a possible way to enlarge the donor pool and to save patients with end-stage liver diseases. However, the safety of hepatitis B virus core antibody positive (HBcAb+) donors has been controversial. Initial studies were mainly conducted overseas with relatively small numbers of HBcAb+ liver recipients, and there are few relevant reports in the population of mainland China. We hypothesized that the safety of HBcAb+ liver grafts is not suboptimal.
AIM To evaluate the safety of using hepatitis B virus (HBV) core antibody-positive donors for liver transplantation in Chinese patients.
METHODS We conducted a retrospective study enrolling 1071 patients who underwent liver transplantation consecutively from 2005 to 2016 at West China Hospital Liver Transplantation Center. Given the imbalance in several baseline variables, propensity score matching was used, and the outcomes of all recipients were reviewed in this study.
RESULTS In the whole population, 230 patients received HBcAb+ and 841 patients received HBcAb negative (HBcAb-) liver grafts. The 1-, 3- and 5-year survival rates in patients and grafts between the two groups were similar (patient survival: 85.8% vs 87.2%, 77.4% vs 81.1%, 72.4% vs 76.7%, log-rank test, P = 0.16; graft survival: 83.2% vs 83.6%, 73.8% vs 75.9%, 70.8% vs 74.4%, log-rank test, P = 0.19). After propensity score matching, 210 pairs of patients were generated. The corresponding 1-, 3- and 5-year patient and graft survival rates showed no significant differences. Further studies illustrated that the post-transplant major complication rates and liver function recovery after surgery were also similar. In addition, multivariate regression analysis in the original cohort and propensity score-matched Cox analysis demonstrated that receiving HBcAb+ liver grafts was not a significant risk factor for long-term survival. These findings were consistent in both HBV surface antigen-positive (HBsAg+) and HBsAg negative (HBsAg-) patients.
Newly diagnosed HBV infection had a relatively higher incidence in HBsAg- patients with HBcAb+ liver grafts (13.23%), in which HBV naive recipients suffered most (31.82%), although this difference did not affect patient and graft survival (P = 0.50 and P = 0.49, respectively). Recipients with a high HBV surface antibody (anti-HBs) titer (more than 100 IU/L) before transplantation and antiviral prophylaxis with nucleos(t)ide antiviral agents post-operation, such as nucleos(t)ide antiviral agents, had lower de novo HBV infection risks.
CONCLUSION HBcAb+ liver grafts do not affect the long-term outcome of the recipients. Combined with proper postoperative antiviral prophylaxis, utilization of HBcAb+ grafts is rational and feasible.

Abstract
AIM Recently, elbasvir/grazoprevir combination therapy (EBR/GZR) was reported to have excellent antiviral effects for chronic genotype 1 hepatitis C virus (HCV) infection. However, it has not been recommended for patients with post-liver transplant (LT) HCV re-infections because of a lack of evidence for effectiveness and drug-drug interactions. METHODS We report the usage of EBR/GZR in five post-LT HCV re-infected patients with the kinetics of renal function and tacrolimus trough levels during and after therapy. Furthermore, to evaluate the antiviral effects, we examined the HCV kinetics during and after therapy and compared this with other interferon-free therapy in post-LT patients (n = 19). RESULTS All patients treated with EBR/GZR therapy obtained rapid virologic response and sustained at 12 weeks post-treatment. There was no evidence of worsening estimated glomerular filtration rates. Three patients were given tacrolimus as immunosuppressive therapy and its trough levels were controllable with dosage adjustments. One patient developed grade 1 diarrhea 3 days after therapy induction. To evaluate the antiviral effects of EBR/GZR therapy for these patients, we compared them to the effects of daclatasvir/asunaprevir combination therapy (n = 8) and sofosbuvir/ledipasvir combination therapy (n = 11). The EBR/GZR combination was not inferior to other therapies in its early phase and late-phase antiviral effects. CONCLUSIONS Although further studies with a larger number of patients are required, we suggest that EBR/GZR therapy is an alternative therapy for patients with post-LT genotype 1 HCV re-infection.

Abstract
Several risk factors for ischaemic-type biliary lesions (ITBL) after liver transplantation (LT) have been identified, but the role of portal vein perfusion at graft procurement is still unclear. This was a prospective study on double aortic and portal perfusion (DP) of liver grafts stratified by donor's decade (<60 yo; 60-69 yo; 70-79 yo and ≥80 yo) versus similar historical cohorts of primary, adult grafts procured with single aortic perfusion (SP) only. The primary study aim was to assess the role of DP on the incidence of ITBL. There was no difference in the incidence of overall biliary complications according to procurement technique for recipients of grafts <80 years. A higher incidence of ITBL was observed for patients receiving grafts ≥80 years and perfused through the aorta only (1.9 vs. 13.4%; P = 0.008). When analysing octogenarian grafts, donor male gender (HR = 6.4; P = 0.001), haemodynamic instability (HR = 4.9; P = 0.008), and type-2 diabetes mellitus (DM2) (HR = 3.0; P = 0.03) were all independent risk factors for ITBL, while double perfusion at procurement (HR = 0.1; P = 0.04) and longer donor intensive care unit (ICU) stay (HR = 0.7; P = 0.04) were protective factors. Dual aortic and portal perfusion has the potential to reduce post-transplant ITBL incidence for recipients of octogenarian donor grafts. Larger series are needed to confirm this preliminary experience.

Abstract
Antiviral therapy to eradicate hepatitis C virus (HCV) infection improves outcomes in patients undergoing liver transplantation (LT) for advanced chronic HCV with or without hepatocellular carcinoma. Traditionally, antiviral therapy focused on the use of interferon (IFN)-based regimens, with antiviral treatment initiated in the posttransplant period once recurrent HCV disease with fibrosis in the allograft was identified. The use of IFN-based therapy was limited in pretransplant patients with advanced liver disease. Earlier intervention, either before transplantation or early after LT, is now feasible with the advent of second-generation direct-acting antiviral agents (DAAs) with superior tolerability and efficacy to IFN-based therapy. These agents have the potential to reduce the number of patients developing HCV-related complications requiring LT and retransplantation, as well as reducing the demand for donor organs. We discuss the pros and cons of pretransplant, peritransplant, and posttransplant therapy with current DAAs, citing available data from clinical trials and real-world experience.

Orthotopic Liver Transplantation With Elderly Donors (Over 80 Years of Age): A Prospective Evaluation. Transplant Proc 2018; 50:3594-3600. [PMID: 30577243 DOI: 10.1016/j.transproceed.2018.08.005] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/04/2018] [Revised: 07/19/2018] [Accepted: 08/03/2018] [Indexed: 12/16/2022]
Abstract
BACKGROUND Our main objective was to assess the clinical outcomes obtained in a single orthotopic liver transplant (OLT) hospital with donors ≥80 years of age compared to a control group of patients subjected to OLT during the same period of time with donors who were under 65 years of age. METHODS A prospective analysis was carried out on all the OLTs performed using liver grafts from donors in a state of brain death and with an age of ≥80 years (study group) between April 2007 and January 2015. The results of the study group (n = 36) were compared with those of a control group of patients less than 65 years of age receiving transplants with grafts. RESULTS A total of 51 potential donors ≥80 years were assessed, with a total of 36 liver transplants being carried out and their results were compared with a control group of 283 patients receiving transplants. The median follow-up time of the patients in the series was 36 months (range: 24-120 months). Graft survival at 1, 2, and 3 years was 77%, 72%, and 62%, respectively, among the patients in the study group and 79%, 73%, and 65% among the patients in the control group, and there were no statistically significant differences. Patient survival at 1, 2, and 3 years was 86%, 82%, and 75%, respectively, among the patients in the study group and 82%, 76%, and 72% among the patients in the control group, also without there being any statistically significant differences. CONCLUSIONS There is no age limit for liver transplant donors. The use of octogenarian donors makes it possible to increase the pool of donors while providing enough safety for the recipient.

Abstract
Using our prospectively collected database all adult hepatitis C virus (HCV)-positive patients receiving an adult-to-adult LDLT between October 2000 and May 2014 were identified. Outcome of LDLT with grafts from younger (<50 years=128) vs older donors (≥50 years=31) was compared. Post-transplant graft function, postoperative complications and incidence of HCV recurrence were evaluated. Long-term graft and patient survival was calculated. No difference in graft function was observed between younger and older grafts. Overall complications were similar between both groups. The severity of complications determined by the Dindo-Clavien score was similar. Graft loss from HCV recurrence was significantly less frequent in younger grafts (18% vs 62%, P = 0.001). Young vs older livers had a trend toward improved 1-, 5-, and 10-year graft survival (89% vs 87%, 77% vs 69%, 70% vs 55%, P = 0.096), while patient survival was comparable between both groups (91% vs 90%, 78% vs 69%, 71% vs 60%, P = 0.25). In conclusion, LDLT with older vs younger grafts are more frequently associated with long-term graft loss due to HCV recurrence. Differences in graft survival might be more prominent with prolonged (≥5-year) follow-up. Living donor-recipient matching is particularly important for younger HCV-positive recipients.

Development of Duodenal Ulcers due to the Discontinuation of Proton Pump Inhibitors After the Induction of Sofosbuvir Plus Ledipasvir Therapy: A Report of Two Cases. Transplant Proc 2018; 50:222-225. [PMID: 29407313 DOI: 10.1016/j.transproceed.2017.12.012] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/13/2017] [Revised: 10/17/2017] [Accepted: 12/05/2017] [Indexed: 12/13/2022]
Abstract
Sofosbuvir plus ledipasvir (SOF-LDV) combination therapy is a promising therapy for post-transplant hepatitis C virus (HCV) reinfection. It is known that gastric pH elevation induces lower absorption of ledipasvir; therefore, the use of proton pump inhibitors (PPIs) should be considered regarding dose reduction after SOF-LDV therapy induction. Here, we report two patients who developed duodenal ulcers due to the discontinuation of PPIs after the induction of SOF-LDV therapy for post-transplant HCV reinfection. The first patient was a 71-year-old man who had undergone living donor liver transplantation due to HCV-related liver cirrhosis. Lansoprazole, 30 mg daily, was discontinued upon SOF-LDV therapy induction. Seven days after SOF-LDV therapy induction, gastrointestinal endoscopy revealed the presence of a duodenal ulcer. The second patient was a 54-year-old man who had undergone living donor liver transplantation due to HCV-related end-stage liver disease. Similar to the first patient, rabeprazole sodium was discontinued upon the induction of SOF-LDV therapy. Eighteen days after SOF-LDV therapy induction, gastrointestinal endoscopy revealed the presence of a duodenal ulcer. In both cases, these duodenal ulcers improved after the resumption of the administration of PPIs, and a sustained virologic response at 12 weeks was achieved by SOF-LDV therapy with PPI use. Thus, PPI use should be continued consistently during SOF-LDV therapy for post-transplant HCV reinfection.

Transplanting hepatitis C virus-positive livers into hepatitis C virus-negative patients with preemptive antiviral treatment: A modeling study. Hepatology 2018; 67:2085-2095. [PMID: 29222916 PMCID: PMC5991982 DOI: 10.1002/hep.29723] [Citation(s) in RCA: 47] [Impact Index Per Article: 7.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/03/2017] [Revised: 10/30/2017] [Accepted: 12/07/2017] [Indexed: 12/11/2022]
Abstract
UNLABELLED Under current guidelines, hepatitis C virus (HCV)-positive livers are not transplanted into HCV-negative recipients because of adverse posttransplant outcomes associated with allograft HCV infection. However, HCV can now be cured post-LT (liver transplant) using direct-acting antivirals (DAAs) with >90% success; therefore, HCV-negative patients on the LT waiting list may benefit from accepting HCV-positive organs with preemptive treatment. Our objective was to evaluate whether and in which HCV-negative patients the potential benefit of accepting an HCV-positive (i.e., viremic) organ outweighed the risks associated with HCV allograft infection. We developed a Markov-based mathematical model that simulated a virtual trial of HCV-negative patients on the LT waiting list to compare long-term outcomes in patients: (1) willing to accept any (HCV-negative or HCV-positive) liver versus (2) those willing to accept only HCV-negative livers. Patients receiving HCV-positive livers were treated preemptively with 12 weeks of DAA therapy and had a higher risk of graft failure than those receiving HCV-negative livers. The model incorporated data from published studies and the United Network for Organ Sharing (UNOS). We found that accepting any liver regardless of HCV status versus accepting only HCV-negative livers resulted in an increase in life expectancy when Model for End-Stage Liver Disease (MELD) was ≥20, and the benefit was highest at MELD 28 (0.172 additional life-years). The magnitude of clinical benefit was greater in UNOS regions with higher HCV-positive donor organ rates, that is, Regions 1, 2, 3, 10, and 11. Sensitivity analysis demonstrated that model outcomes were robust. CONCLUSION Transplanting HCV-positive livers into HCV-negative patients with preemptive DAA therapy could improve patient survival on the LT waiting list. Our analysis can help inform clinical trials and minimize patient harm. (Hepatology 2018;67:2085-2095).

Severe Hepatitis C Recurrence as a Risk Factor for Opportunistic Infections in Liver Transplant Recipients. Transplant Proc 2018; 50:1437-1443.

Abstract
OBJECTIVE The aim of the study was to determine the clinical characteristics, frequency of opportunistic infections (OI), and the outcomes for liver transplant recipients with severe hepatitis C virus (HCV) recurrence. In addition, the objective was to evaluate HCV recurrence as a risk factor for developing an OI. METHODS We conducted a retrospective observational study recording all liver transplant recipients from July 1, 2003, to December 31, 2012. Patients with liver disease due to HCV were selected. Active surveillance of infections was conducted periodically, and patients were classified according to presence of severe HCV recurrence. RESULTS Three hundred seventy patients underwent liver transplantation because of chronic HCV. One hundred forty-seven patients presented severe recurrence (SR) (49%) and 50 (17%) of them had post-liver transplant cholestatic hepatitis C. Patients with SR presented OI, especially cytomegalovirus (CMV) infections and invasive fungal infections, more frequently than patients without SR (33% vs 13%; P < .001). From the diagnosis of SR to the presentation of OI, the median number of days was 169 (6-2083). Acute allograft rejection (OR 1.8 95% confidence interval [CI] 1.1-3.3) donor age ≥60 years (OR 2.9 95% CI 1.3-6.8), and SR (OR 2.8, 95% CI 1.6-5.1) were independently associated with the development of OI in liver transplant recipients. CONCLUSION A high index of suspicion of opportunistic infections must be maintained when faced with severe HCV recurrence in liver transplant recipients. Moreover, active surveillance against CMV infection and other prophylactic strategies against opportunistic infections should be considered.

Abstract
BACKGROUND & AIMS Oral direct-acting antivirals (DAAs) for hepatitis C virus (HCV) treatment offer new hope to both pre- and post-liver transplant (LT) patients. However, whether to treat HCV patients before vs after LT is not clear because treatment can improve liver function but could reduce the chance of receiving an LT while on the waiting list. Our objective was to evaluate the cost effectiveness of pre-LT vs post-LT HCV treatment with oral DAAs in decompensated cirrhotic patients on the LT waiting list. METHODS We used a validated mathematical model that simulated a virtual trial comparing long-term clinical and cost outcomes of pre-LT vs post-LT HCV treatment with oral DAAs. Model parameters were estimated from United Network for Organ Sharing data, SOLAR-1 and 2 trials, and published studies. For each strategy, we estimated the quality-adjusted life-year, life expectancy, cost, and the incremental cost-effectiveness ratio. RESULTS For lower MELD scores, quality-adjusted life-years were higher with pre-LT HCV treatment compared with post-LT treatment. Pre-LT HCV treatment was cost saving in patients with MELD scores of 15 or less, and cost effective in patients with MELD scores of 16 to 21. In contrast, post-LT HCV treatment was cost effective in patients with MELD scores of 22 to 29 and cost saving if MELD scores were 30 or higher. Results varied by drug prices and by United Network for Organ Sharing regions. CONCLUSIONS For cirrhotic patients awaiting LT, pre-LT HCV treatment with DAAs is cost effective/saving in patients with MELD scores of 21 or lower, whereas post-LT HCV treatment is cost effective/saving in patients with MELD scores of 22 or higher.

Abstract
INTRODUCTION Due to the current organ shortage, nearly 20% of patients die waiting for a liver transplant (LT). The average donor age is on the rise, and grafts from elderly donors are offered as extended criteria grafts. METHODS This is a meta-analysis comparing the outcome differences of adult patients undergoing LT using grafts from <70-year-old donors vs >70-year-old donors. The primary end-points were graft and patient survival. Secondary outcomes were biliary and vascular complications as well as graft function. The odds ratio (OR) is a summary statistic with the corresponding 95% confidence interval; P < .05 was considered to be statistically significant. RESULTS Eight nonrandomized comparative studies with 4376 LT recipients were included. About 79.9% and 20.1% of the grafts were from <70-year-old and >70-year-old donors, respectively. Graft survival at 1 year was similar between the two groups (P = .11), but there was better 3-year and 5-year graft survival in the >70-year-old group (P = .006 and P < .0001, respectively). Patient survival was also similar between the groups at 1 year (P = .54), but with better survival at 3-year and 5-year follow-ups (P = .007 and P < .0001, respectively) in the >70-year-old group. There were no statistically significant differences in the incidence of biliary, vascular, and graft functional-related complications. CONCLUSION Liver grafts from selected >70-year-old donors do not pose added organ-specific risks and thus have comparable transplantation outcomes.

Abstract
AIM This study aimed to clarify the efficacy and safety of interferon-free therapy using asunaprevir and daclatasvir, or sofosbuvir and ledipasvir for post living donor liver transplantation (LDLT) recipients with hepatitis C virus (HCV). METHODS A retrospective cohort study of LDLT recipients with HCV genotype 1b treated with asunaprevir (100 mg twice daily) and daclatasvir (60 mg once daily), or sofosbuvir (400 mg/day) and ledipasvir (90 mg/day) was carried out. RESULTS Ten patients without mutations in the area of L31 and Y93 completed the treatment with asunaprevir and daclatasvir. Five of them had end-stage chronic kidney disease, including three hemodialysis patients. Of the 10 patients, nine completed the protocol of 24 weeks; one stopped the treatment due to the development of aortic valve stenosis. All nine patients who completed the 24-week treatment protocol achieved end of treatment response. Nineteen patients received treatment with sofosbuvir and ledipasvir. Of the 19 patients, 18 completed the protocol of 12 weeks; one stopped treatment due to severe interstitial pneumonia. All 18 patients who completed the 12-week treatment protocol achieved end of treatment response. All patients in both treatment groups who completed the regimen and reached 3 months after the end of treatment achieved sustained virological response at 12 weeks after treatment. Liver functions were significantly improved at the end of treatment, and no adverse events were observed. CONCLUSIONS Interferon-free therapy using asunaprevir and daclatasvir, or sofosbuvir and ledipasvir, is highly effective for post-LDLT recipients with HCV genotype 1b.

Abstract
In 2006, derivation of the donor risk index (DRI) highlighted the importance of donor factors for successful liver transplantation. Over the last decade, the DRI has served as a useful metric of donor quality and has enhanced our understanding of donor factors and their impact upon recipients with hepatitis C virus, those with low Model for End-Stage Liver Disease (MELD) score, and individuals undergoing retransplantation. DRI has provided the transplant community with a common language for describing donor organ characteristics and has served as the foundation for several tools for organ risk assessment. It is a useful tool in assessing the interactions of donor factors with recipient factors and their impact on posttransplant outcomes. However, limitations of statistical modeling, choice of donor factors, exclusion of unaccounted donor and geographic factors, and the changing face of the liver transplant recipient have tempered its widespread use. In addition, the DRI was derived from data before the MELD era but is currently being applied to expand the donor pool while concurrently meeting the demands of a dynamic allocation system. A decade after its introduction, DRI remains relevant but may benefit from being updated to provide guidance in the use of extended criteria donors by accounting for the impact of geography and unmeasured donor characteristics. DRI could be better adapted for recipients with nonalcoholic fatty liver disease by examining and including recipient factors unique to this population. Liver Transplantation 23 1216-1225 2017 AASLD.

Abstract
Background Recurrent hepatitis C virus (HCV) infection after liver transplantation (LT) has been a frequent and relevant problem in the past two decades. This analysis evaluated the efficacy and safety of new interferon (IFN)-free direct-acting antiviral (DAA) therapies in a large real-world cohort of HCV patients after LT. Methods We retrospectively analyzed a cohort of 157 patients infected with HCV who underwent deceased donor LT between 1997 and 2014. Patient survival, outcome, and side effects of antiviral therapy were assessed. Results Survival with recurrent HCV genotype 1 (GT1) infection was inferior to other HCV GTs (P=0.01). The overall sustained virological response (SVR) rate with new DAA therapy was 94.6% (n=37). Patients with both GT1 and other GTs reached SVR rates >90%. We noticed a few side effects, mainly caused by ribavirin, and only one discontinuation in DAA-treated patients. Conclusion DAA therapy was effective and safe in previous hard-to-treat patients after LT in this real-world cohort.

Abstract
OBJECTIVE To evaluate the whole experience of liver transplantation (LT) with donors ≥70 years in a single center not applying specific donor/recipient matching criteria. BACKGROUND LT with very old donors has historically been associated with poorer outcomes. With the increasing average donor age and the advent of Model for End-stage Liver Diseases (MELD) score-based allocation criteria, an optimal donor/recipient matching is often unsuitable. METHODS Outcomes of all types of LTs were compared according to 4 study groups: patients transplanted between 1998 and 2003 with donors <70 (group 1, n = 396) or ≥70 years (group 2, n = 88); patients transplanted between 2004 and 2010 with donors <70 (group 3, n = 409), or ≥70 years (group 4, n = 190). From 2003, graft histology was routinely available before cross-clamping, and MELD-driven allocation was adopted. RESULTS Groups 1 and 2 were similar for main donor and recipient variables, and surgical details. Group 4 had shorter donor ICU stay, lower rate of moderate-to-severe graft macrosteatosis (2.3% vs 8%), and higher recipient MELD score (22 vs 19) versus group 3. After 2003, median donor age, recipient age, and MELD score significantly increased, whereas moderate-to-severe macrosteatosis and ischemia time decreased. Five-year graft survival was 63.6% in group 1 versus 59.1% in group 2 (P = 0.252) and 70.9% in group 3 versus 67.6% in group 4 (P = 0.129). Transplants performed between 1998 and 2003, recipient HCV infection, balance of risk score >18, and pre-LT renal replacement treatments were independently associated with worse graft survival. CONCLUSIONS Even without specific donor/recipient matching criteria, the outcomes of LT with donors ≥70 and <70 years are comparable with appropriate donor management.

Abstract
BACKGROUND Older liver grafts have been considered in the past decade due to organ shortage. The aim was to compare outcomes after liver transplantation with either younger or older donors. METHODS Patients transplanted in our center between 2004 and 2014 with younger donors (younger than 60 years; n = 253) were compared with older donors (older than 75 years; n = 157). Multiorgan transplantations, split grafts, or non-heart-beating donors were not included. RESULTS Donors in the older group were mostly women deceased from stroke, and only 3 patients had experienced cardiac arrest. Liver tests were significantly better in the older group than in the younger group. There was no difference regarding cold ischemia time, model for end-stage liver disease score, and steatosis. There was no significant difference regarding primary nonfunction and dysfunction, hepatic artery and biliary complications, and retransplantation rates. Graft survival was not different (65% and 64% in the older and younger groups, P = 0.692). Within the older group, hepatitis C infection, retransplantation, and emergency transplantation were associated with poor graft survival. CONCLUSIONS Provided normal liver tests and the absence of cardiac arrest in donors, older liver grafts (>75 years) may be safely attributed to non-hepatitis C-infected recipients in the setting of a first and nonurgent transplantation.

Abstract
Posttransplant hepatitis C virus (HCV) recurrence is universal in chronic hepatitis C recipients. Antiviral therapy is suggested after liver transplant to halt disease progression. Pegylated interferon plus ribavirin therapy remains the standard of care in many areas where direct antiviral agents are poorly accessible. This study aimed to assess the treatment efficacy and safety of the regimen for Taiwanese patients with post-transplant HCV recurrence. Nine patients with HCV recurrence postliver transplantation were allocated. Patients received either pegylated interferon α-2a 180 μg/wk or pegylated interferon α-2b 1.5 mg/kg/wk plus ribavirin for 24-48 weeks. The primary endpoint was the achievement of sustained virological response (SVR), defined as undetectable HCV RNA throughout 6 months of follow-up after the end of treatment. The safety profiles were also documented. The rates of rapid virological response, early virological response, end-of-treatment virological response, and SVR were 33%, 63%, 75%, and 56% respectively. Of the four patients who failed antiviral treatment, the treatment responses were nonresponse (n = 1), loss of follow-up (n = 1), and relapse (n = 2). Three patients terminated therapy early due to severe adverse events, including severe anemia, intra-abdomen infection, and hepatocellular carcinoma recurrence. One of the three patients who terminated treatment early at Week 6 experienced rapid virological response followed by SVR. Pegylated interferon/ribavirin combination allowed a chance for cure with a fair SVR rate in Taiwanese chronic hepatitis C patients postliver transplantation. Early identification of side effects and careful monitoring during therapy might enhance the treatment efficacy.

Future of liver disease in the era of direct acting antivirals for the treatment of hepatitis C. World J Hepatol 2017; 9:352-367.

Abstract
Hepatitis C virus (HCV) infection has been a global health problem for decades, due to the high number of infected people and to the lack of effective and well-tolerated therapies. In the last 3 years, the approval of new direct acting antivirals characterized by high rates of virological clearance and excellent tolerability has dramatically improved HCV infection curability, especially for patients with advanced liver disease and for liver transplant recipients. Long-term data about the impact of the new direct acting antivirals on liver fibrosis and liver disease-related outcomes are not yet available, due to their recent introduction. However, previously published data deriving from the use of pegylated-interferon and ribavirin lead to hypothesizing that we are going to observe, in the future, a reduction in mortality and in the incidence of hepatocellular carcinoma, as well as a regression of fibrosis for people previously affected by hepatitis C. In the liver transplant setting, clinical improvement has already been described after treatment with the new direct acting antivirals, which has often led to patients delisting. In the future, this may hopefully reduce the gap between liver organ request and availability, probably expanding liver transplant indications to other clinical conditions. Therefore, these new drugs are going to change the natural history of HCV-related liver disease and the epidemiology of HCV infection worldwide. However, the global consequences will depend on treatment accessibility and on the number of countries that could afford the use of the new direct acting antivirals.

Abstract
The availability of oral direct-acting antivirals has altered the hepatitis C virus (HCV) treatment paradigm for both pre-liver transplant (LT) and post-LT patients. There is a perceived trade-off between pre-LT versus post-LT treatment of HCV-treatment may improve liver function but potentially decrease the likelihood of a necessary LT. Our objective was to identify LT-eligible patients with decompensated cirrhosis who would benefit (and not benefit) from pre-LT treatment based on their Model for End-Stage Liver Disease (MELD) scores. We simulated a virtual trial comparing long-term outcomes of pre-LT versus post-LT HCV treatment with oral direct-acting antivirals for patients with MELD scores between 10 and 40. We developed a Markov-based microsimulation model, which simulated the life course of patients on the transplant waiting list and after LT. Simulation of LT integrated data from recent trials of oral direct-acting antivirals (SOLAR 1 and 2), the United Network for Organ Sharing (UNOS), and other studies. The outcomes of the model included life expectancy, 1-year and 5-year patient survival, and mortality. Model-predicted patient survival was validated with UNOS data. We found that, at the national level, treating HCV before LT increased life expectancy if MELD was ≤27 but could decrease life expectancy at higher MELD scores. Depending on the UNOS region, the threshold MELD score to treat HCV pre-LT varied between 23 and 27 and was lower for UNOS regions 3, 10, and 11 and higher for regions 1, 2, 4, 5, 8, and 9. Sensitivity analysis showed that the thresholds were stable. CONCLUSION Our findings suggest that the optimal MELD threshold below which decompensated cirrhosis patients should receive HCV treatment while awaiting LT is between 23 and 27, depending on the UNOS region.
