Abstract
Liver transplantation (LT) recipients have experienced a significant improvement in short-term survival during the past 3 decades attributed to advancements in surgical techniques, perioperative management, and effective immunosuppressive regimens. However, long-term survival is affected by a high incidence of metabolic disorders and their consequences, including cardiovascular disease (CVD) and malignancies. Pretransplant metabolic impairments especially in those with nonalcoholic steatohepatitis cirrhosis are aggravated by the addition of posttransplant weight gain, physical inactivity, and reversal from catabolic to anabolic state. Moreover, although immunosuppressants are vital to avoid graft rejection, long-term exposure to these medications is implicated in metabolic impairments after LT. In this review, we summarize the molecular pathogenesis of different metabolic disorders after LT, including diabetes mellitus, dyslipidemia, and nonalcoholic fatty liver disease. Furthermore, CVD, malignancies, and graft rejections were provided as significant complications of post-LT metabolic conditions threatening both the patient and graft survival. Ultimately, emerging preventive and treatment strategies for posttransplant diabetes mellitus are summarized. This review highlights the significant need for more clinical trials of antihyperglycemic agents in LT recipients. Also, translational studies will help us to better understand the molecular and genetic factors underlying these metabolic complications and could lead to more personalized management in this high-risk population.

Abstract
Life-long immunosuppression has always been considered the key in managing liver graft protection from recipient rejection. However, it is associated with severe adverse effects that lead to increased morbidity and mortality, including infections, cardiovascular diseases, kidney failure, metabolic disorders and de novo malignancies. This explains the great interest that has developed in the concept of tolerance in recent years. The liver, thanks to its marked tolerogenicity, is to be considered a privileged organ: up to 60% of selected patients undergoing liver transplantation could safely withdraw immunosuppression.

Abstract
Donor specific transfusions have been the basis of tolerance inducing protocols since Peter Medawar showed that it was experimentally feasible in the 1950s. Though trials of cellular therapies have become increasingly common in solid organ transplantation, they have not become standard practice. Additionally, whereas some protocols have focused on cellular therapies as a method for donor antigen delivery—thought to promote tolerance in and of itself in the correct immunologic context—other approaches have alternatively focused on the intrinsic immunosuppressive properties of the certain cell types with less emphasis on their origin, including mesenchymal stem cells, regulatory T cells, and regulatory dendritic cells. Regardless of intent, all cellular therapies must contend with the potential that introducing donor antigen in a new context will lead to sensitization. In this review, we focus on the variety of cellular therapies that have been applied in human trials and non-human primate models, describe their efficacy, highlight data regarding their potential for sensitization, and discuss opportunities for cellular therapies within our current understanding of the immune landscape.

Abstract
Although significant progress has been made to improve short-term survival of transplant patients, long-term acceptance of allografts in solid organ and hematopoietic stem cell (HSC) transplantation is still a significant challenge. Current therapeutics for preventing or treating allograft rejection rely on potent immunosuppressive drugs that primarily target T cells of the adaptive immune response. Promising advances in transplant immunology have highlighted the importance of innate immune responses in allograft acceptance and rejection. Recent studies have demonstrated that innate immune cells are capable of mediating memory-like responses during inflammation, a term known as trained innate immunity. In this process, innate immune cells, such as macrophages and monocytes, undergo metabolic and epigenetic changes in response to a primary stimulus with a pathogen or their products that result in faster and more robust responses to a secondary stimulus. There is also some evidence to suggest that innate immune cells or their progenitors may be more anti-inflammatory after initial stimulation with appropriate agents, such as helminth products. Although this phenomenon has primarily been studied in the context of infection, there is emerging evidence to suggest that it could play a vital role in transplantation rejection and tolerance. Mechanisms of training innate immune cells and their progenitors in the bone marrow are therefore attractive targets for mediating long-term solid organ and HSC transplant tolerance. In this review, we highlight the potential role of proinflammatory and anti-inflammatory mechanisms of trained innate immunity in solid organ and HSC transplantation.

Clin Transplant 2021; 35:e14433. [PMID: 34289179 DOI: 10.1111/ctr.14433] [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: 09/23/2020] [Revised: 07/08/2021] [Accepted: 07/11/2021] [Indexed: 11/30/2022]
Abstract
BACKGROUND Liver Transplantation has advanced over the past 3 decades, with 1-year survival rates improving 25%. Survival rates for those transplanted has increased to remarkable levels, but survival from the time of listing may not be as revolutionary. METHODS Kaplan-Meier with log-rank test as well as Cox regression analysis was used to retrospectively analyze 211 610 adults listed for LT and 116 299 adult transplant recipients from 1987 to 2016. Our primary endpoints were survival from time of listing to waitlist death or posttransplant death. RESULTS One-year survival following LT improved dramatically (68% in 1987-1988 vs. 93% in 2016, P < .001). There was no improvement in 1-year intent-to-treat survival: 78.4% for those listed in 1987 and 81.8% for those listed in 2016 (P = .1). Also observed were decreases in the percentage of transplanted candidates from 74.8% in 1987-1988 to 54.7% in 2016 (P < .001) and increased 1-year wait-list mortality from 12.5% in 1987-1988 to 22.6% in 2016 (P = .002). CONCLUSION As transplant rate has decreased while waitlist mortality has increased, no improvements have been made in intent-to-treat survival of patients listed for transplant over the past 3 decades. We speculate this observation to be resultant of a relative donor shortage outpaced by waitlist growth. SUMMARY Liver Transplantation has experienced vast increases in survival rates over the past 3 decades; however, due to an increased donor supply outpaced by waitlist growth, the rate of transplantation has decreased significantly while the waitlist mortality has increased, leading to no improvement in 1-year intent-to-treat survival rates.

Abstract
Background: Care and treatment adherence are important factors for given good liver transplantation outcomes. Objectives: Design and validate an instrument to appraise adherence to care and treatment in liver transplantation recipients. Methods: A mixed-methods sequential exploratory study was conducted in two phases from 2017 to 2019, in the Liver Transplantation Clinic Tehran, Iran. In the qualitative phase, the concept of care and treatment adherence in liver transplantation recipients extracted by a conventional content analysis was performed on semi-structural interviews that were conducted on 18 liver transplantation recipients that were recruited through purposive sampling technique. Also, two physicians, one nurse coordinator of the liver transplantation team, and two family members were interviewed. The scale was developed based on operational definitions extracted from the qualitative phase. The validity was assessed by face, content, construct validity, and confirmatory factor analysis. The reliability was also evaluated by calculating test-retest intraclass correlation coefficient and Cronbach's alpha. The exploratory factor analysis was carried out with 286 filled the questionnaire. Results: Four factors were extracted in factor analysis. These factors explained 45.622% of the variance. The final version of the scale consisted of 20 items. The Cronbach's alpha coefficient reported as 0.889 for the total scale and the intraclass correlation coefficient was reported as 0.912. The confirmatory factor analysis led to a fitting model. Chi-square indices were reported as CMIN/DF = 2.34, NFI = 0.94, CFI = 0.96, and RAMSEA = 0.067. Conclusions: With a four factors structure, validity and reliability of adherence to care and treatment scale are acceptable; therefore, it can be used for appraisal care and treatment adherence in liver transplant recipients.

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. [PMID: 34098075 DOI: 10.1016/j.ijsu.2021.105981] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/22/2021] [Revised: 04/28/2021] [Accepted: 05/25/2021] [Indexed: 01/05/2023]
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.

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
Pediatric kidney transplant recipients generally have good outcomes post-transplantation. However, the younger age and longer life span after transplantation in the pediatric population make understanding the multifactorial nature of long-term graft survival critical. This investigation analyzes factors associated with 10-year survival to identify areas for improvement in patient care. Kaplan-Meier with log-rank test and univariable and multivariable logistic regression methods were used to retrospectively analyze 7785 kidney transplant recipients under the age of 18 years from January 1, 1998, until March 9, 2008, using United Network for Organ Sharing (UNOS) data. Our end-point was death-censored 10-year graft survival after excluding recipients whose grafts failed within one year of transplant. Recipients aged 5-18 years had lower 10-year graft survival, which worsened as age increased: 5-9 years (OR: 0.66; CI: 0.52-0.83), 10-14 years (OR: 0.43; CI: 0.33-0.55), and 15-18 years (OR: 0.34; CI: 0.26-0.44). Recipient African American ethnicity (OR: 0.67; CI: 0.58-0.78) and Hispanic donor ethnicity (OR: 0.82; CI: 0.72-0.94) had worse outcomes than other donor and recipient ethnicities, as did patients on dialysis at the time of transplant (OR: 0.82; CI: 0.73-0.91). Recipient private insurance status (OR: 1.35; CI: 1.22-1.50) was protective for 10-year graft survival. By establishing the role of age, race, and insurance status on long-term graft survival, we hope to guide clinicians in identifying patients at high risk for graft failure. This study highlights the need for increased allocation of resources and medical care to reduce the disparity in outcomes for certain patient populations.

Abstract
BACKGROUND Details of perioperative outcomes and survival after gastric cancer surgery in prior transplant recipients have received minimal research attention. METHODS We performed an observational cohort study using the database of 20,147 gastric cancer patients who underwent gastrectomy at a single gastric cancer center in Korea. Forty-one solid organ recipients [kidney (n = 35), liver (n = 5), or heart (n = 1)] were matched with 205 controls using propensity score matching. RESULTS Operation time, blood loss, and postoperative pain were similar between groups. Short-term complication rates were similar between transplantation and control groups (22.0% vs. 20.1%, P = 0.777). Transplantation group patients with stage 1 gastric cancer experienced no recurrence, while those with stage 2/3 cancer had significantly higher recurrence risk compared to the controls (P = 0.049). For patients with stage 1 cancer, the transplantation group had a significantly higher rate of non-gastric cancer-related deaths compared to the controls (19.2% vs. 1.4%, P = 0.001). For those with stage 2/3 cancer, significantly lower proportion of the transplantation group received adjuvant chemotherapy compared to the control group (26.7% vs. 80.3%, P < 0.001). The transplantation group had a higher (albeit not statistically significant) rate of gastric cancer-related deaths compared to the controls (40.0% vs. 18.0%, P = 0.087). CONCLUSION Transplant recipients and non-transplant recipients exhibited similar perioperative and short-term outcomes after gastric cancer surgery. From long-term outcome analyses, we suggest active surveillance for non-gastric cancer-related deaths in patients with early gastric cancer, as well as strict oncologic care in patients with advanced cancer, as effective strategies for transplant recipients.

Abstract
Patients with nonresectable liver metastases from colorectal cancer have few therapeutic options and a dismal prognosis. Although liver transplantation for this indication has historically a poor reputation, recent advances in the field of chemotherapy and immunosuppression have paved the way to revisit the concept. New data have shown promising results that need to be validated in several ongoing clinical trials. Since liver grafts represent a scarce resource, several new tools are being explored to expand the donor pool for this indication. The purpose of this review is to present all current available data and perspectives about liver transplantation for nonresectable liver metastases from colorectal cancer.

Abstract
Background Liver transplantation (LT) is a life-saving treatment for patients with end-stage liver disease and acute liver failure. However, in-hospital death cannot be avoided. We designed this study to analyze patients' in-hospital mortality rate after LT and the factors correlated with in-hospital death. Methods The data of patients who received LT in our hospital between January 11, 2015, and November 19, 2019, were obtained from the China Liver Transplant Registry and medical records. The in-hospital mortality rate was calculated, and factors related to mortality, cause of death, and factors related to cause of death were analyzed by reviewing patients' data. Results A total of 529 patients who underwent cadaveric LT were enrolled in this study. Modified piggyback orthotopic LT was performed for all patients. Seventy patients died in the hospital after LT, and the in-hospital mortality rate was 13.2%. Factors including model for end-stage liver disease (MELD) score, Child-Pugh grading, intraoperative blood loss, and anhepatic phase were correlated with in-hospital death. MELD score and intraoperative blood loss were determined as the two independent risk factors of in-hospital death. The first two causes of death were infection (34.3%) and primary non-function (15.7%). Pulmonary fungal infection was the main cause of infectious death. MELD score was the independent risk factor for infectious death, and both body mass index of donors and cold ischemic time were independent risk factors of primary non-function. Conclusions In-hospital death poses a threat to certain patients undergoing LT. Our study suggests that the main cause of in-hospital death is an infection, followed by primary non-function.

Abstract
Liver transplant (LT) recipients require life-long immunosuppression (IS) therapy to preserve allograft function. The risks of chronic IS include an increased frequency of malignancy, infection, renal impairment, and other systemic toxicities. Despite advances in IS, long-term LT outcomes have not been improved over the past three decades. Standard-of-care (SoC) therapy can, in rare cases, lead to development of operational tolerance that permits safe withdrawal of maintenance IS. However, successful IS withdrawal cannot be reliably predicted and, in current prospective studies, is attempted several years after the transplant procedure, after considerable exposure to the cumulative burden of maintenance therapy. A recent pilot clinical trial in liver tolerance induction demonstrated that peri-transplant immunomodulation, using a regulatory T-cell (Treg) approach, can reduce donor-specific alloreactivity and allow early IS withdrawal. Herein we review protocols for active tolerance induction in liver transplantation, with a focus on identifying tolerogenic cell populations, as well as barriers to tolerance. In addition, we propose the use of novel IS agents to promote immunomodulatory mechanisms favoring tolerance. With numerous IS withdrawal trials underway, improved monitoring and use of novel immunomodulatory strategies will help provide the necessary knowledge to establish an active liver tolerance induction protocol for widespread use.

Abstract
Background Although the risk factors for chronic kidney disease progression after deceased donor liver transplantation have been widely reported, there are few reports describing the factors associated with kidney function changes in patients after living donor liver transplantation (LDLT). This study aims to further investigate these kidney function change factors. Material/Methods This retrospective study was performed using the data of patients who underwent LDLT at the Nagasaki University Hospital, Japan from August 2000 to November 2017. Factors contributing to post-transplantation estimated glomerular filtration rate (eGFR) changes were analyzed. Results A total of 191 cases were reviewed. The average age was 53.8 years, and 108 (56.5%) patients were male. Compared to pre-transplantation eGFR levels, eGFR 1 year after LDLT improved in 65 patients (34%) and deteriorated in 126 patients (66%). Multivariate regression analysis revealed that pre-transplant diuretics (P=0.04) and tacrolimus trough value 1 year after transplantation (P=0.04) were significantly associated with elevated eGFR changes. eGFR elevation 1 year after LDLT was more pronounced in patients with a low tacrolimus trough level 1 year after LDLT (P=0.01). Therefore, mycophenolate mofetil was added to tacrolimus in patients with poor renal function before LDLT. Conclusions Tacrolimus trough level was associated with eGFR changes 1 year after LDLT. The adjusted dose of tacrolimus and combined use of other immunosuppressants may be important to maintain renal function after LDLT.

Abstract
PURPOSE OF REVIEW Achieving operational tolerance remains a priority in liver transplantation. Although several biomarkers of tolerance and rejection have been identified, few have been reproducible and validated across centers, and therefore have yet to reach clinical practice. Here we summarize findings from prior seminal studies and review current developments in profiling the liver allograft. RECENT FINDINGS Substantial efforts and progress have been made in the recent years towards the discovery of reliable biomarkers that can predict and guide successful immunosuppression withdrawal. Recent studies have also investigated the transcriptomic signatures underlying not only acute rejection but also subclinical inflammation and chronic allograft injury. SUMMARY As new genomic and sequencing technologies continue to develop, clinical trials are underway to validate biomarkers of tolerance, as well as better understand the mechanisms of both acute and subclinical rejection, with the goal of maximizing allograft survival. Altogether, this will hopefully enable the implementation of immunosuppression withdrawal protocols into clinical practice and make operational tolerance reliably attainable in the near future.

Abstract
De novo gastric cancer after living donor liver transplantation. Distal gastrectomy after splenectomy. ICG is useful for evaluating the blood flow in gastrectomy after LDLT with splenectomy.
Introduction The incidence of de novo malignancies after organ transplantation is increasing. We herein report a patient who developed gastric cancer after living donor liver transplantation (LDLT) and splenectomy. Intraoperative indocyanine green (ICG) fluorescence angiography immediately after gastrectomy was useful for evaluating the blood supply into the remnant stomach in this patient. Presentation of case A 69-year-old woman underwent LDLT and splenectomy for end-stage liver disease. Gastric cancer was found by an endoscopic examination eight years after LDLT. Although total gastrectomy was considered due to previous splenectomy, we decided to intraoperatively evaluate the flow of the remnant stomach using ICG fluorescence. After ligation of the left gastric artery and transection of the stomach with a sufficient proximal margin from the tumor, intraoperative ICG fluorescence angiography showed abundant intramural blood flow of the remnant stomach. We were able to preserve the proximal stomach with confidence and she recovered smoothly after the operation without any signs of acute rejection. Conclusion Intraoperative ICG fluorescence angiography may be helpful for evaluating the blood flow in the remnant stomach during surgery for de novo gastric cancer after LDLT.

Abstract
INTRODUCTION The value of hepatocellular carcinoma (HCC) surveillance is defined by the balance of benefits, i.e., early tumor detection, and potential harms, related to false positive and indeterminate results. Although physical harms can be observed in 15%-20% of patients with cirrhosis undergoing HCC surveillance, previous cost-effectiveness analyses have not incorporated costs of harms. We aimed to evaluate the cost-effectiveness of HCC surveillance including both benefits and harms. DESIGN We constructed a Markov model to compare surveillance strategies of ultrasound (US) alone, US and alpha fetoprotein (AFP), and no surveillance in 1 million simulated patients with compensated cirrhosis. Harms included imaging and biopsy in patients undergoing surveillance for HCC. Model inputs were based on literature review, and costs were derived from the Medicare fee schedule, with all costs inflated to 2018 dollars. The primary outcome was the incremental cost-effectiveness ratio per incremental quality-adjusted life-year. RESULTS In the base case analysis, US with AFP was the dominant strategy over both US alone and no surveillance. In a probabilistic sensitivity analysis, US with AFP was the most cost-effective strategy in 80.1% of simulations at a willingness-to-pay threshold of $100,000 per quality-adjusted life-year. In our threshold analyses, an HCC incidence >0.4% per year and surveillance adherence >19.5% biannually were necessary for US with AFP to be cost-effective compared with no surveillance. DISCUSSION Accounting for both surveillance-related benefits and harms, US and AFP is more cost-effective for HCC surveillance than US alone or no surveillance in patients with compensated cirrhosis.

DSA Are Associated With More Graft Injury, More Fibrosis, and Upregulation of Rejection-associated Transcripts in Subclinical Rejection. Transplantation 2020; 104:551-561.

Abstract
BACKGROUND Subclinical T cell-mediated rejection (subTCMR) is commonly found after liver transplantation and has a good short-term prognosis, even when it is left untreated. Donor-specific antibodies (DSA) are putatively associated with a worse prognosis for recipient and graft after liver transplantation. METHODS To assess the immune regulation in subTCMR grafts, gene expression of 93 transcripts for graft injury, tolerance, and immune regulation was analyzed in 77 biopsies with "no histologic rejection" (NHR; n = 25), "clinical TCMR" (cTMCR; n = 16), and subTCMR (n = 36). In addition, all available subTCMR biopsies (n = 71) were tested for DSA with bead assays. RESULTS SubTCMR showed heterogeneous and intermediate expression profiles of transcripts that were upregulated in cTCMR. Graft gene expression suggested a lower activation of effector lymphocytes and a higher activation of regulatory T cells in grafts with subTCMR compared to cTCMR. DSA positivity in subTCMR was associated with histological evidence of more severe graft inflammation and fibrosis. This more severe DSA+ associated graft injury in subTCMR was converged with an upregulation of cTCMR-associated transcripts. In nonsupervised analysis, DSA positive subTCMR mostly clustered together with cTCMR, while DSA negative subTCMR clustered together with NHR. CONCLUSIONS T cell-mediated rejection seems to form a continuum of alloimmune activation. Although subTCMR exhibited less expression of TCMR-associated transcript, DSA positivity in subTCMR was associated with an upregulation of rejection-associated transcripts. The identification of DSA positive subclinical rejection might help to define patients with more inflammation in the graft and development of fibrosis.

Abstract
The majority of liver grafts exhibit abnormal histological findings late after transplantation, even when liver enzymes are normal. Such subclinical graft injuries were associated with rejection and fibrosis progression in recent studies. The identification of non-invasive biomarkers for subclinical graft injury might help to individualize immunosuppression. Therefore, graft injury was assessed in 133 liver biopsies with normal/near normal liver enzymes from a prospective liver biopsy program. Cytokeratin-18 cell death marker (M65) and donor specific anti-HLA antibodies (DSA) were measured as non-invasive markers in paired plasma samples in addition to routine parameters. M65 was associated with subclinical graft injury but this association was too weak for reasonable clinical application. DSA positivity was associated with more graft inflammation (OR = 5.4) and more fibrosis (OR = 4.2). Absence of DSA excluded fibrosis in 87–89%, while presence of DSA excluded histological criteria for immunosuppression minimization attempts in 92–97%. While CK18 cell death marker had no diagnostic value for the detection of subclinical liver graft injury, DSA testing can help to preselect patients for immunosuppression reduction in case of DSA negativity, while DSA positivity should prompt elastography or liver biopsy for the assessment of subclinical graft injury.

Abstract
BACKGROUND Although short-term outcomes for liver transplantation have improved, patient and graft survival are limited by infection, cancer, and other complications of immunosuppression. Rapid induction of tolerance after liver transplantation would decrease these complications, improving survival and quality of life. Tolerance to kidneys, but not thoracic organs or islets, has been achieved in nonhuman primates and humans through the induction of transient donor chimerism. Since the liver is considered to be tolerogenic, we tested the hypothesis that the renal transplant transient chimerism protocol would induce liver tolerance. METHODS Seven cynomolgus macaques received immune conditioning followed by simultaneous donor bone marrow and liver transplantation. The more extensive liver surgery required minor adaptations of the kidney protocol to decrease complications. All immunosuppression was discontinued on postoperative day (POD) 28. Peripheral blood chimerism, recipient immune reconstitution, liver function tests, and graft survival were determined. RESULTS The level and duration of chimerism in liver recipients were comparable to those previously reported in renal transplant recipients. However, unlike in the kidney model, the liver was rejected soon after immunosuppression withdrawal. Rejection was associated with proliferation of recipient CD8 T effector cells in the periphery and liver, increased serum interleukin (IL)-6 and IL-2, but peripheral regulatory T cell (Treg) numbers did not increase. Antidonor antibody was also detected. CONCLUSIONS These data show the transient chimerism protocol does not induce tolerance to livers, likely due to greater CD8 T cell responses than in the kidney model. Successful tolerance induction may depend on greater control or deletion of CD8 T cells in this model.

BACKGROUND Liver Transplantation (LT) is a life-saving treatment for end-stage liver disease, for which various outcomes are measured in randomized clinical trials (RCT). The aim of this methodological review is to evaluate and classify outcomes reported in RCT in LT. METHODS PubMed and ClinicalTrials.gov were searched in July 2018 for published and ongoing RCTs on LT in the last 5 years. Studies were eligible if focusing on first LT in adult patients, with interventions during the perioperative period. Data extracted concerned LT characteristics, type of intervention, methodological characteristics and outcomes assessed. RESULTS Of 2685 references, 55 were included with a median of 78 (40-120) patients for published trials and planned to include 117 (55-218) patients for ongoing trials. Morbidity was the most frequently used as primary outcome in 37 published (67%) and 13 ongoing trials (54%). We identified 10 different definitions for graft dysfunction, 9 for recovery outcomes and 12 different time-points for mortality. For published trials, among the 397 outcomes specified in the method section, results were reported for 283 (71%). CONCLUSION Outcomes reported in LT trials are very heterogeneous. A consensus approach to develop a core outcome set (COS) should be considered allowing for comparisons of results across trials. PROSPERO CRD42018108146.

Abstract
BACKGROUND Traditional methods for rejection control in transplanted patients are considered invasive, risky, and prone to sampling errors. Using molecular biomarkers as an alternative protocol to biopsies, for monitoring rejection may help to mitigate some of these problems, increasing the survival rates and well-being of patients. Recent advances in omics technologies provide an opportunity for screening new molecular biomarkers to identify those with clinical utility. OBJECTIVE This systematic literature review (SLR) aimed to summarize existing evidence derived from large-scale expression profiling regarding differentially expressed mRNA and miRNA in graft rejection, highlighting potential molecular biomarkers in transplantation. METHODS The study was conducted following PRISMA methodology and the BiSLR guide for performing SLR in bioinformatics. PubMed, ScienceDirect, and EMBASE were searched for publications from January 2001 to January 2018, and studies (i) aiming at the identification of transplant rejection biomarkers, (ii) including human subjects, and (iii) applying methodologies for differential expression analysis from large-scale expression profiling were considered eligible. Differential expression patterns reported for genes and miRNAs in rejection were summarized from both cross-organ and organ-specific perspectives, and pathways enrichment analysis was performed for candidate biomarkers to interrogate their functional role in transplant rejection. RESULTS A total of 821 references were collected, resulting in 604 studies after removal of duplicates. After application of inclusion and exclusion criteria, 33 studies were included in our analysis. Among the 1517 genes and 174 miRNAs identifed, CXCL9, CXCL10, STAT1, hsa-miR-142-3p, and hsa-miR-155 appeared to be particularly promising as biomarkers in transplantation, with an increased expression associated with transplant rejection in multiple organs. In addition, hsa-miR-28-5p was consistently decreased in samples taken from rejected organs. CONCLUSION Despite the need for further research to fill existing knowledge gaps, transcriptomic technologies have a relevant role in the discovery of accurate biomarkers for transplant rejection diagnostics. Studies have reported consistent evidence of differential expression associated with transplant rejection, although issues such as experimental heterogeneity hinder a more systematic characterization of observed molecular changes. Special attention has been giving to large-scale mRNA expression profiling in rejection, whereas there is still room for improvements in the characterization of miRnome in this condition.

Abstract
Background Sleep disturbance is a common problem in liver transplant recipients, but few studies have confirmed the psychosocial factors associated with sleep quality in patients after liver transplantation. This study aimed to identify the psychosocial factors related to sleep quality among liver transplant patients during outpatient follow-up. Material/Methods A retrospective cross-sectional study was performed in 124 liver transplant patients during outpatient follow-up. All participants completed a general demographic questionnaire, the Pittsburgh Sleep Quality Index (PSQI), the Generalized Anxiety Disorder-7 scale (GAD-7), the Patient Health Questionnaire-9 (PHQ-9), and the perceived social support scale (PSSS). Results The mean global PSQI score was 6.57 (SD, 4.28), which was significantly higher than the mean score for people with normal sleep quality; 50 (40.3%) recipients were classified as having poor sleep quality (PSQI >7). Among the self-reported sleep problems, 62 (50.0%) participants reported that they had to go to the bathroom at night, 58 (43.5%) woke up in the middle of the night or early morning, 84 (67.7%) reported depression symptoms, and 116 (93.5%) had low-level social support. The global PSQI score was positively correlated with anxiety and depression scores, while the global PSSS score was negatively correlated with anxiety and depression scores (p<0.01). Multiple linear regression analysis showed that the length of the post-liver transplant period, the type of residence, BMI, depressive symptoms, and anxiety symptoms were important factors affecting sleep quality among liver transplant patients (p<0.05). Conclusions Our findings showed high prevalence and incidence of poor sleep quality in liver transplant recipients in outpatient follow-up, with significant correlations with anxiety, depression, and social support, and it was affected by multiple factors. This indicates a need for further research on the follow-up results of sleep and the benefits of comprehensive interventions involving psychosocial factors in liver transplant recipients in China.

Physical Condition, Glycemia, Liver Function, and Quality of Life in Liver Transplant Recipients After a 12-Month Supervised Exercise Program. Transplant Proc 2019; 51:2952-2957. [PMID: 31607623 DOI: 10.1016/j.transproceed.2019.03.087] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/14/2019] [Accepted: 03/10/2019] [Indexed: 12/15/2022]
Abstract
BACKGROUND AND AIMS Despite the excellent long-term outcomes in liver transplant (LT) recipients, several medical complications related to lifestyle still represent an issue. This study examined the effects of a 12-month supervised aerobic and strength training program on the aerobic capacity, muscle strength, metabolic profile, liver function, and quality of life of a cohort of LT recipients. METHODS LT recipients with stable liver function were assigned to interventional exercise (group A) or usual care (group B). Aerobic capacity, muscle strength, metabolic profile, liver and kidney function, and health-related quality of life were assessed at baseline and after 6 and 12 months. Group A attended supervised training sessions 3 times per week for 12 months. Group B received general recommendations about home-based exercise. RESULTS Forty patients from 6 Italian LT centers were randomized. Twenty-nine (72.5%, men-to-women ratio 23:6, mean age, 52 ± 8 years) LT recipients completed the study. Baseline characteristics were similar between groups except for body mass index and time from LT. No episode of acute rejection nor increase of transaminases occurred. Maximum workload and body mass index increased in both groups over time, but fasting glucose significantly decreased in group A (94.0 ± 15.0 mg/dL vs 90.0 ± 17.0 mg/dL; P = .037) and increased in controls (95.0 ± 24.0 mg/dL vs 102.0 ± 34.0 mg/dL, P = .04). Upper limb muscle strength increased only in supervised LT recipients. Vitality and general and mental health domains significantly improved after physical exercise. CONCLUSIONS Supervised combined training was safe and effective in increasing aerobic capacity, muscle strength, and quality of life and in improving glucose metabolism in stable LT recipients.

Abstract
BACKGROUND Although MELD score is a reliable tool for estimating mortality in the waiting list, criteria for preoperative prediction of survival after liver transplantation (LT) are lacking. ALBI score was validated as a prognostic marker for hepatocellular carcinoma patients undergoing transarterial chemoembolization, hepatic resection, and sorafenib treatment but not for LT outcomes yet. This study aimed to evaluate ALBI score as a prognostic factor in LT. METHODS This is a single-center analysis of patients undergoing LT between October 2001 and June 2017. Primary endpoint was overall post-LT mortality. Secondary endpoint was 90-day mortality. RESULTS Of all 301 patients included in this study, 185 (61.5%) were males. The median age was 54.1 ± 11.3 years. Univariate and multivariate analysis revealed that ALBI grade 3 (HR 1.836, 95% CI 1.154-2.921, p = 0.010), low serum albumin (HR 0.628, 95% CI 0.441-0.893, p = 0.010), black race (HR 2.431, 95% CI 1.160-5.092, p = 0.019), and elevated body mass index (HR 1.061, 95% CI 1.022-1.102, p = 0.002) all were associated with decreased overall survival following LT. Patients with both ALBI grade 3 (n = 25) and calculated MELD score ≥ 25 had the lowest overall survival (p < 0.001). DISCUSSION ALBI grade 3 was related to lower post-LT survival and can be utilized as a tool for risk stratification in LT.

Abstract
The standard therapy for decompensated end-stage chronic liver disease of any etiology and acute fulminant hepatic failure is liver transplantation (LT). Advances in immunosuppressive therapy decreased the rates of acute and chronic rejections. Thus, graft and patient survivals have significantly improved. However, long-term adverse effects of prolonged use of immunosuppressive agents such as malignancies, opportunistic infections, metabolic disorders, and other organ toxicities have now become a major concern. Consequently, alternative approaches are needed to deescalate the customary drugs and their side effects. Therapy must be individualized and additional preventive measures should be taken by patients with particular risk factors or predisposed to certain adverse effects. Current opinion favors a combination of agents with different mechanism of actions and toxicity profiles. Corticosteroids are employed in immediate and early postoperative period. Although they have a pronounced side effect profile, calcineurin inhibitors (CNIs) are still the backbone of early and late phase immunosuppressive regimens because of their proved efficacy. Antimetabolites are frequent choices for steroid and/or CNI-sparing strategies. Studies also have established a role for mammalian target of rapamycin (mTOR) inhibitors in specific groups of recipients. Biologic agents are a hot topic of interest and made their way into current strategies for induction. Agents extrapolated from other transplantation or immunologic experience are being evaluated.

Abstract
OBJECTIVES To explore trends in liver transplantation (LT) and outcomes for older recipients for evaluation, counseling, and appropriate referral of this vulnerable group of older adults. DESIGN Prospective national cohort study. SETTING Scientific Registry of Transplant Recipients (January 1, 2003-December 31, 2016). PARTICIPANTS Older (aged ≥ 65) deceased donor liver-only transplant recipients (n=8,627). MEASUREMENTS We evaluated temporal changes in recipient, donor, and transplant characteristics and post-LT length of stay (LOS), acute rejection, graft loss, and mortality using logistic regression and Cox proportional hazards. RESULTS LT in older adults almost quadrupled, from 263 in 2003 (9.5% of total LTs that year) to 1,144 in 2016 (20.7% of total LTs). Recent recipients were more likely to be female and African American and have a higher body mass index and Model for End-Stage Liver Disease score. Hepatitis C, nonalcoholic steatohepatitis, and hepatocellular carcinoma were the most common indications for LT in recent recipients. Odds of LOS longer than 2 weeks decreased 34% from 2003-06 to 2013-16 (adjusted odds ratio (aOR)=0.66, 95% confidence interval (CI)=0.57-0.76, P < .001), 1-year acute rejection decreased 30% (aOR=0.70, 95% CI=0.56-0.88, P = .002), all-cause graft loss decreased 54% (adjusted hazard ratio (aHR)=0.46, 95% CI=0.40-0.52, P < .001), and mortality decreased 57% (aHR=0.43, 95% CI=0.38-0.49, P < .001). CONCLUSION Despite the substantial increase in the number of older adults undergoing LT and the severity of their condition, LOS, rejection, graft loss, and mortality have significantly decreased over time. These trends can help guide appropriate LT referral and counseling in older adults with end-stage liver disease. J Am Geriatr Soc 66:2321-2326, 2018.
