[PMID: 38857316 DOI: 10.1097/lvt.0000000000000419] [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: 01/08/2024] [Accepted: 05/24/2024] [Indexed: 06/12/2024]
Abstract
Autoimmune liver diseases (AILDs) constitute the fourth most common indication for liver transplantation (LT) across the world. In general, the outcomes after LT are acceptable; however, disease recurrence after LT is common for all AILD, which can negatively affect graft and overall survival. Several questions persist, including the risk factors associated with recurrent disease, optimal antirejection medications, strategies to reduce the risk of recurrence, and how to best incorporate these strategies into clinical practice. For that reason, we assembled an international group of experts to review evidence to address these outstanding questions regarding LT for AILD. Survival rates after LT are ~90% and 70% at 1 and 5 years, and recurrent disease occurs in 10%-50% of patients with AILD. In patients with disease recurrence, graft survival decreased by 18% and 28% and overall survival by 8% and 12% at 5 and 10 years after LT, respectively. Recurrent autoimmune hepatitis is associated with high aminotransferases and immunoglobulin G (IgG) before LT, lymphoplasmacytic infiltrates in the explants, and may be associated with the absence of steroids after LT. However, the efficiency and safety of triple immunosuppressive maintenance therapy is still debatable. Younger age at diagnosis with primary biliary cholangitis or LT is associated with primary biliary cholangitis recurrence. Preventive use of ursodeoxycholic acid reduces the risk of recurrence and has a benefit in graft and patient survival. Episodes of systemic inflammation, including T-cell-mediated rejection, active ulcerative colitis, and episodes of cholangitis, are associated with recurrent PSC. Recurrent disease for AILD is associated with worse graft and patient survival. Patients with autoimmune hepatitis could be considered for long-term low-dose predniso(lo)ne, whereas patients with primary biliary cholangitis should be placed on preventive ursodeoxycholic acid after LT. There are no specific treatments for PSC recurrence; however, adequate control of inflammatory bowel disease and optimal immunosuppression to avoid T-cell-mediated rejection should be encouraged.

Liu D, Youssef MM, Grace JA, Sinclair M. Relative carcinogenicity of tacrolimus vs mycophenolate after solid organ transplantation and its implications for liver transplant care. World J Hepatol 2024; 16:650-660. [PMID: 38689747 PMCID: PMC11056899 DOI: 10.4254/wjh.v16.i4.650] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/16/2023] [Revised: 01/30/2024] [Accepted: 03/19/2024] [Indexed: 04/24/2024] Open
Abstract
BACKGROUND De novo malignancy is a leading cause of late morbidity and mortality in liver transplant recipients. Cumulative immunosuppression has been shown to contribute to post-transplant malignancy (PTM) risk. There is emerging evidence on the differential carcinogenic risk profile of individual immunosuppressive drugs, independent of the net effect of immunosuppression. Calcineurin inhibitors such as tacrolimus may promote tumourigenesis, whereas mycophenolic acid (MPA), the active metabolite of mycophenolate mofetil, may limit tumour progression. Liver transplantation (LT) is relatively unique among solid organ transplantation in that immunosuppression monotherapy with either tacrolimus or MPA is often achievable, which makes careful consideration of the risk-benefit profile of these immunosuppression agents particularly relevant for this cohort. However, there is limited clinical data on this subject in both LT and other solid organ transplant recipients. AIM To investigate the relative carcinogenicity of tacrolimus and MPA in solid organ transplantation. METHODS A literature search was conducted using MEDLINE and Embase databases using the key terms "solid organ transplantation", "tacrolimus", "mycophenolic acid", and "carcinogenicity", in order to identify relevant articles published in English between 1st January 2002 to 11th August 2022. Related terms, synonyms and explosion of MeSH terms, Boolean operators and truncations were also utilised in the search. Reference lists of retrieved articles were also reviewed to identify any additional articles. Excluding duplicates, abstracts from 1230 records were screened by a single reviewer, whereby 31 records were reviewed in detail. Full-text articles were assessed for eligibility based on pre-specified inclusion and exclusion criteria. RESULTS A total of 6 studies were included in this review. All studies were large population registries or cohort studies, which varied in transplant era, type of organ transplanted and immunosuppression protocol used. Overall, there was no clear difference demonstrated between tacrolimus and MPA in de novo PTM risk following solid organ transplantation. Furthermore, no study provided a direct comparison of carcinogenic risk between tacrolimus and MPA monotherapy in solid organ transplantation recipients. CONCLUSION The contrasting carcinogenic risk profiles of tacrolimus and MPA demonstrated in previous experimental studies, and its application in solid organ transplantation, is yet to be confirmed in clinical studies. Thus, the optimal choice of immunosuppression drug to use as maintenance monotherapy in LT recipients is not supported by a strong evidence base and remains unclear.

Abstract
The long-term (>5 y) outcomes following liver transplantation (LT) have not been extensively reported. The aim was to evaluate outcomes of LT recipients who have survived the first 5 years. A multicenter retrospective analysis of prospectively collected data from 3 high volume LT centers (Dallas-USA, Birmingham-UK, and Barcelona-Spain) was undertaken. All adult patients, who underwent LT since the inception of the program to December 31, 2010, and survived at least 5 years since their LT were included. Patient survival was the primary outcome. A total of 3682 patients who survived at least 5 years following LT (long-term survivors) were included. Overall, median age at LT was 52 years (IQR 44-58); 53.1% were males; and 84.6% were Caucasians. A total of 49.4% (n=1820) died during a follow-up period of 36,828 person-years (mean follow-up 10 y). A total of 80.2% (n=1460) of all deaths were premature deaths. Age-standardized all-cause mortality as compared to general population was 3 times higher for males and 5 times higher for females. On adjusted analysis, besides older recipients and older donors, predictors of long-term mortality were malignancy, cardiovascular disease, and dialysis. Implementation of strategies such as noninvasive cancer screening, minimizing immunosuppression, and intensive primary/secondary cardiovascular prevention could further improve survival.

Abstract
BACKGROUND Fas ligand (FasL) is one ligand that activates extrinsic apoptosis pathway. High expression in lymphocytes of FasL have been found in patients with acute rejection of liver transplantation (LT). No high blood concentrations of soluble FasL (sFasL) have been found in patients with acute LT rejection; however, the samples size of those studies was small.
AIM To determine whether patients with hepatocellular carcinoma (HCC) that dead during the first year of LT have higher blood sFasL concentrations previously to LT that those who that remain alive in a study of higher sample size.
METHODS Patients underwent LT due to HCC were included in this retrospective study. Serum sFasL levels prior to LT were measured and one-year LT mortality was registered.
RESULTS Non-surviving patients (n = 14) showed higher serum sFasL levels [477 (269-496) vs 85 (44-382) pg/mL; P < 0.001] than surviving patients (n = 113). Serum sFasL levels (pg/mL) were associated with mortality (OR = 1.006; 95%CI = 1.003-1.010; P = 0.001) independently of age of LT donor in the logistic regression analysis.
CONCLUSION We report for the first time that HCC patients who die within the first year of HT have higher blood sFasL concentrations prior to HT than those who remain alive.

Abstract
Carbapenem-resistant Acinetobacter baumannii bacteremia (CRAB-B) is a fatal infectious complication of liver transplantation (LT). This study investigated the incidence, effects, and risk factors associated with CRAB-B during the early post-LT period. Among 1051 eligible LT recipients, 29 patients experienced CRAB-B within 30 days of LT with a cumulative incidence of 2.7%. In the patients with CRAB-B (n = 29) and matched controls (n = 145) by nested-case control design, the cumulative incidence of death on days 5, 10, and 30 from the index date was 58.6%, 65.5%, and 65.5%, and 2.1%, 2.8%, and 4.2%, respectively (p < .001). Pre-transplant MELD (OR 1.11, 95% confidence interval [CI] 1.04-1.19, p = .002), severe encephalopathy (OR 4.62, 95% CI 1.24-18.61, p = .025), donor body mass index (OR .57, 95% CI .41-.75, p < .001), and reoperation (OR 6.40, 95% CI 1.19-36.82, p = .032) were independent risk factors for 30-day CRAB-B. CRAB-B showed extremely high mortality within 30 days after LT, especially within 5 days after its occurrence. Therefore, assessment of risk factors and early detection of CRAB, followed by proper treatment, are necessary to control CRAB-B after LT.

Abstract
Autoimmune liver diseases (AILDs) are a group of conditions where immune-mediated liver damage can lead to the need for transplantation. Collectively, they account for almost a quarter of all liver transplants. Outcomes in terms of graft and patient survival for all liver transplants have improved markedly over decades with improvements in patient selection, surgical techniques and longer-term care and this is also seen in patients with AILDs. The current five- and ten-year survival rates post-transplant in autoimmune disease are excellent, at 88% and 78%, respectively. A key factor in maintaining good outcomes post liver transplant for these autoimmune conditions is the immunosuppression strategy. These patients have increased the rates of rejection, and autoimmune conditions can all recur in the graft ranging from 12 to 60% depending on the population studied. Immunosuppressive regimens are centred on calcineurin inhibitors, often combined with low dose corticosteroids, with or without the addition of antimetabolite therapy. There is no clear evidence-based immunosuppressive regimen for these conditions, and a tailored approach balancing the individuals' immunological profile against the risks of immunosuppression is often used. There are disease-specific considerations to optimised graft function including the role of ursodeoxycholic acid in both primary biliary cholangitis and primary sclerosing cholangitis and the role and timing of colectomy in primary sclerosing cholangitis in inflammatory bowel disease patients. However, unmet needs still exist in the management of AILDs post liver transplantation particularly in building the evidence base for optimal immunosuppression as well as mitigating the risk of recurrent disease.

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

Abstract
BACKGROUND & AIMS Management of long-term immunosuppression following liver transplantation (LT) remains empirical. Surveillance liver biopsies in combination with transcriptional profiling could overcome this challenge by identifying recipients with active alloimmune-mediated liver damage despite normal liver tests, but this approach lacks applicability. Our aim was to investigate the utility of non-invasive tools for the stratification of stable long-term survivors of LT, according to their immunological risk and need for immunosuppression. METHODS We conducted a cross-sectional multicentre study of 190 adult LT recipients assessed to determine their eligibility to participate in an immunosuppression withdrawal trial. Patients had stable liver allograft function and had been transplanted for non-autoimmune non-replicative viral liver disease >3 years before inclusion. We performed histological, immunogenetic and serological studies and measured the intrahepatic transcript levels of an 11-gene classifier highly specific for T cell-mediated rejection (TCMR). RESULTS In this cohort, 35.8% of patients harboured clinically silent fibro-inflammatory liver lesions (13.7% had mild damage and 22.1% had moderate-to-severe damage). The severity of liver allograft damage was positively associated with TCMR-related transcripts, class II donor-specific antibodies (DSAs), ALT, AST, and liver stiffness measurement (LSM), and negatively correlated with serum creatinine and tacrolimus trough levels. Liver biopsies were stratified according to their TCMR transcript levels using a cut-off derived from biopsies with clinically significant TCMR. Two multivariable prediction models, integrating ALT+LSM or ALT+class II DSAs, had a high discriminative capacity for classifying patients with or without alloimmune damage. The latter model performed well in an independent cohort of 156 liver biopsies obtained from paediatric liver recipients with similar inclusion/exclusion criteria. CONCLUSION ALT, class II DSAs and LSM are valuable tools to non-invasively identify stable LT recipients without significant underlying alloimmunity who could benefit from minimisation of immunosuppression. LAY SUMMARY A large proportion of liver transplant patients with normal liver tests have inflammatory liver lesions, which in 17% of cases are molecularly indistinguishable from those seen at the time of rejection. ALT, class II donor-specific antibodies and liver stiffness are useful in identifying patients with this form of subclinical rejection. We propose these markers as a useful tool to help clinicians determine if the immunosuppression administered is adequate.

Abstract
BACKGROUND There is limited information concerning whether social determinants of health affect postliver transplant (LT) outcomes. This study aims to understand to what extent the health of LT recipients' counties of residence influence long-term LT outcomes. METHODS We used the United Network for Organ Sharing data to identify adult LT recipients transplanted between January 2010 and June 2018. Patient-level data were matched to county-level County Health Ranking (CHR) data using transplant recipient zip code, and nationwide CHRs were created. Mixed-effects Cox proportional hazards models were used to examine associations between CHRs and graft and patient survival post-LT. RESULTS Health outcomes rank was significantly associated with posttransplant graft and patient survival, with worst tertile counties showing a 13% increased hazard of both graft failure and patient mortality compared to the best tertile counties. CONCLUSIONS Although county health is associated with LT outcomes, it also appears that LT recipient selection is effective at mitigating major disparities based on county of residence and helps yield equitable outcomes in this respect.

Abstract
Previous studies have demonstrated cardiovascular causes to be among the leading causes of death after liver (LT) and kidney transplantation (KT). Although both recipient populations have unique pre-transplant cardiovascular burdens, they share similarities in post-transplant exposure to cardiovascular risk factors. The aim of this study was to compare cardiovascular mortality after LT and KT.We analyzed causes of death in 370 consecutive LT and 207 KT recipients from in-hospital records at a single tertiary transplant center. Cardiovascular causes of death were defined as cardiac arrest, heart failure, pulmonary embolism, or myocardial infarction.After a median follow-up of 36.5 months, infection was the most common cause of death in both cohorts, followed by cardiovascular causes in KT recipients and graft-related causes in LT recipients in whom cardiovascular causes were the third most common. Cumulative incidence curves for cardiovascular mortality computed with death from other causes as the competing risk were not significantly different (P = .36). While 1-year cumulative cardiovascular mortality was similar (1.6% after LT and 1.5% after KT), the estimated 4-year probability was higher post-KT (3.8% vs. 1.6%). Significant pre-transplant risk factors for overall mortality after KT in multivariable analysis were age at transplantation, left ventricular ejection fraction <50%, and diastolic dysfunction grade 2 or greater, while significant risk factors for cardiovascular mortality were peripheral artery disease and left ventricular ejection fraction <50%. In the LT group no variables remained significant in a multivariable model for either overall or cardiovascular mortality.The present study found no significant overall difference in cardiovascular mortality after LT and KT. While LT and KT recipients may have similar early cardiovascular mortality, long-term risk is potentially lower after LT. Differing characteristics of cardiovascular death between these two patient populations should be further investigated.

Abstract
The survival of liver transplantation (LT) recipients has been improved remarkably in short-term. The major causes of mortality in long-term include nonimmunological causes such as cardiovascular, de novo malignancy, chronic kidney disease, and recurrence of primary disease. Rejection-related mortality is rare in the long-term after LT. We discuss nonrejection causes of long-term morbidity/mortality, risk factors, and management strategies in LT recipients. In addition, we discuss osteoporosis, contraception, and pregnancy in LT recipients.

Abstract
Liver transplantation has led to great improvements in long-term survival in patients with decompensated liver disease and hepatocellular carcinoma. Cardiovascular disease is the leading cause of non-graft-related deaths and has increased prevalence in liver allograft recipients. This is partly secondary to higher post-transplant rates of metabolic risk factors-notably obesity, hypertension, dyslipidemia, and diabetes mellitus, which comprise metabolic syndrome. Post-transplantation metabolic syndrome is expected to be a growing factor in morbidity and mortality as transplant candidates trend older, the rates of metabolic risk factors in the general population increase, non-alcoholic steatohepatitis grows disproportionally as an indication for transplantation, and post-transplantation survival lengthens. This review discusses the incidence and contributory factors for post-transplant increases in metabolic disease, as well as the burden of cardiovascular disease in the liver allograft recipient. Patients with pre-transplant diabetes or obesity are at particularly high risk for post-transplant metabolic syndrome, and would likely benefit from closer surveillance and more aggressive medical management of risk factors. In metabolic disease resistant to initial medical therapies, tailoring of immunosuppressive regimens may further assist in minimizing long-term cardiovascular disease, although this must be done with caution to avoid worsening the risk of graft failure.

Abstract
GOALS We sought to compare posttransplant outcomes between autoimmune liver disease. BACKGROUND Autoimmune liver diseases, namely primary biliary cholangitis (PBC), primary sclerosing cholangitis (PSC), and autoimmune hepatitis (AIH) generally have favorable posttransplant outcomes. PSC is known to require more retransplantation compared with PBC, however, comparisons to AIH are lacking. We sought to compare graft survival and the need for retransplant in AIH compared with other autoimmune liver disease. STUDY We compared posttransplant graft survival among the 3 entities using Cox regression and competing for risk analyses using the United Network for Organ Sharing (UNOS) database. RESULTS We found AIH is associated with significantly decreased graft survival compared with PBC [hazard ratio: 0.86; 95% confidence interval (CI): 0.77-0.96] and PSC (hazard ratio: 0.89; 95% CI: 0.8-0.99) after controlling for potential confounders. This is mainly driven by posttransplant death. On competing for risk analysis, AIH was associated with higher risk of death compared with PBC [subdistribution hazard ratio (SHR): 0.79; 95% CI: 0.7-0.89] and PSC (SHR: 0.72; 95% CI: 0.64-0.82) and lower risk of retransplant compared with PSC (SHR: 1.48; 95% CI: 1.19-1.8). CONCLUSION As prior studies have shown the similar risk of disease recurrence in AIH and PSC, our study indicates at least part of the increased posttransplant mortality in AIH may be due lower retransplantation rate in this population.

Abstract
Background and Aims A 40% risk of disease recurrence post-liver transplantation (LT) for autoimmune hepatitis (AIH) has been previously reported. Risk factors for recurrence and its impact on long-term patient outcome are poorly defined. We aimed to assess prevalence, time to disease recurrence, as well as patient and graft survival in patients with recurrent AIH (rAIH) versus those without recurrence. Methods Single-center retrospective study of adult recipients who underwent LT for AIH between January 2007 and December 2017. Patients with AIH overlap syndromes were excluded. Results A total of 1436 LTs were performed during the study period, of whom 46 (3%) for AIH. Eight patients had AIH overlap syndromes and were excluded. Patients were followed up for 4.4 ± 3.4 years and mean age at LT was 46.8 years. Average transplant MELD (Model for End-Stage Liver Disease) score was 24.9. About 21% of patients (8 of 38) were transplanted for acute onset of AIH; 66% of patients (n = 25) received a deceased donor liver graft, and 34% a living donor organ. rAIH occurred in 7.8% (n = 3/38) of recipients. Time to recurrence was 1.6, 12.2 and 60.7 months. Patient and graft survival in patients without recurrence was 88.6% and 82.8% in 5 years, whereas in those with rAIH, it was 66.7%, respectively. Conclusion Although AIH recurs post-LT, our data indicate a lower recurrence rate when compared to the literature and excellent patient and graft survival.

Abstract
Objective: This scoping review aims at systematically mapping reported prognostic factors for spontaneous immunosuppression (IS) free allograft tolerance (operational tolerance, OT) in non-viral hepatitis and non-autoimmune disease liver transplant (LT) recipients who are undergoing immunosuppression withdrawal (ISW). The results may inform the subsequent conduct of a systematic review with a more specific review question. Background: LT is currently the most effective treatment for end-stage liver diseases. Whereas the short-term outcomes after LT have dramatically improved over the last decades, the long-term outcomes remain unsatisfactory, mainly because of side effects of lifelong IS, such as infections, cardiovascular diseases, malignancies, and nephrotoxicity. ISW studies have shown that OT can be achieved by a subset of LT recipients and recent research has identified biomarkers of OT in these patients. However, an evidence-based selection algorithm for patients that can predictably benefit from ISW is not available to date. The planned review will, therefore, map existing knowledge on prognostic clinical parameters and biomarkers for OT. Inclusion criteria: We will consider studies that record any clinical parameter or biomarker before the initiation of ISW in paediatric or adult non-viral hepatitis and non-autoimmune disease LT recipients and analyse their possible association with ISW outcomes (OT or non-tolerance). Studies addressing the effectiveness of OT-inducing treatments will be excluded. Methods: Embase, MEDLINE, and Cochrane Library will be searched for relevant articles or conference abstracts. Full-texts of selected abstracts will be independently screened for inclusion by two reviewers. References and citing articles of included records will be screened for additional relevant records. Clinical trial registries will be searched for ongoing studies, and their investigators contacted for the sharing of unpublished data. Data from included records will be independently extracted by two reviewers using a prespecified data extraction table and presented in both tabular and narrative form.

Abstract
Cardiovascular events are the second most prevalent cause of non-hepatic mortality in liver transplant recipients. The incidence of these events is projected to rise because of the growing prevalence of non-alcoholic steatohepatitis as a transplant indication and the ageing population of liver transplant recipients. Recipients with metabolic syndrome are up to four times more likely to have a cardiovascular event than recipients without, therefore prevention and optimal treatment of the components of metabolic syndrome are key in reducing the risk of these events. Although data on the treatment of metabolic comorbidities specifically in liver transplant recipients are scarce, there is detailed guidance from learned societies that mostly mirrors the guidance for patients at increased cardiovascular risk in the general population. In this Review, we discuss the management of the components of metabolic syndrome following liver transplantation and provide practical stepwise guidance. We also emphasise the need for adequately powered studies for the treatment of metabolic comorbidities in liver transplant recipients.

Abstract
Background: Higher liver caspase-3 activity has been found in patients with different liver diseases. However, there is no published data about circulating caspase-3 levels in patients with hepatocellular carcinoma (HCC) who underwent liver transplantation (LT). Therefore, our objective in this study was to determine whether an association between circulating caspase-3 levels in HCC patients prior to LT and one-year mortality after LT exists. Methods: In this observational and retrospective study, we included HCC patients who underwent LT. We measured serum levels of caspase-3 (as the main executor of apoptosis) and caspase-cleaved cytokeratin (CCCK)-18 (to estimate apoptosis degree) before LT. Results: One-year surviving LT patients (n = 129) showed lower serum levels of caspase-3 (p = 0.004) and CCCK-18 (p = 0.001) than non-surviving LT patients (n = 16). Logistic regression analysis showed that serum caspase-3 levels prior to LT were associated with one-year after LT mortality (Odds Ratio = 2.612; 95% CI = 1.519-4.493; p = 0.001). We found a positive association between serum levels of caspase-3 and CCCK-18 (rho = 0.26; p = 0.002). Conclusions: Our study is the first one reporting data of circulating caspase-3 levels prior to LT for HCC, and an association between high serum caspase-3 levels previously to LT and survival at first year after LT.

Abstract
Hepatocellular carcinoma (HCC) as an indication to liver transplant (LT) started as palliative treatment, then moved to potentially curative anti-cancer therapy and more recently entered the era of competition with non-cancer indications, consequent to the need of the society to target equal distribution of the limited resource of donated organs among different indications. Nowadays HCC is a leading indication to LT, currently representing up to 50% of the indications in most transplant Centers. The risk of post-transplant death and the causes of mortality significantly vary along the post-transplant follow-up. Overall, the main causes of death after LT are multiple organ failure and cerebrovascular, cardiovascular, pulmonary, and renal complications. However, after the first post-LT year, mortality for technical complications, infections and general complications significantly decrease, while recurrence of primary liver diseases (particularly malignancies) increase, turning to be the main causes of death. In studies with time-to-event or survival outcomes, a competing risk is an event whose occurrence precludes the occurrence of the primary event of interest. In the setting of LT for HCC, when the primary outcome of interest is death due to HCC recurrence, death due to causes different from this serves as a competing event because subjects who die from such different causes are no longer at risk of death due to HCC recurrence. The introduction of HCC-specific survival as a primary endpoint in studies assessing the outcomes of LT for HCC allows the identification of independent oncologic determinants of post-LT survival and their relative weight on patients' prognosis. In this view, a continuous model based on level of AFP, tumor size and tumor number that allows to determine the risk of death from HCC-related factors after liver transplantation ( www.hcc-olt-metroticket.org/ ) has been recently developed. Since the endpoint of HCC-specific survival is not influenced by the changes observed in short-term post-LT survival (thanks to advances in the clinical management) nor in long-term post-LT survival (thanks to the introduction of effective treatments achieving control of hepatitis B and C viruses), a model predicting HCC-specific survival will be an helpful prognostic tool in the context of the changing scenarios of LT for HCC.

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
Clinical indications for liver transplantation (LT) in patients with autoimmune hepatitis (AIH) are identical to those of patients with other chronic liver diseases that end in acute or semiacute liver failure, decompensated cirrhosis, or hepatocellular carcinoma. Recurrent disease after LT has been reported in 10%-50% of patients with AIH, and the frequency of detection is influenced in part by the use of protocol or clinically indicated liver biopsy. De novo AIH connotes the development of AIH in patients transplanted for liver diseases other than AIH, and it has been reported in 5%-10% of pediatric and 1%-2% of adult recipients. Recurrent disease can negatively impact on graft and patient survival, and retransplantation has been required in 8%-23%. De novo AIH is within the spectrum of graft dysfunction that includes plasma cell-rich rejection, and it can also progress to cirrhosis and graft failure. Treatment for recurrent or de novo disease is based on the conventional regimens for AIH, and corticosteroid therapy alone or combined with azathioprine is standard. Better control of disease activity prior to LT has been associated with less recurrence, and maintenance corticosteroid treatment after LT can reduce its frequency. In conclusion, recurrent AIH is far more frequent than de novo AIH. Both may have negative impacts on graft and patient survival, and early detection and treatment are key objectives. Future investigations must codify the diagnostic criteria for each graft dysfunction, seek diagnostic biomarkers, and evaluate treatments that improve outcomes without increasing the risk of pre- and post-LT infections.

Abstract
INTRODUCTION Although the revised cardiac risk index (RCRI) is a useful tool for estimating the risk of postoperative cardiac events, whether it improves the prediction of cardiac events in patients undergoing liver transplantation (LT) has not been sufficiently demonstrated. METHODS We retrospectively analyzed 1429 patients who underwent LT. Cardiac events were defined as myocardial infarction, death, or combined events within 30 days after surgery. The RCRI was defined as the number of independent predictors including high-risk surgery, ischemic heart disease, congestive heart failure, cerebrovascular disease, insulin treatment, and creatinine level >2 mg/dL. Multivariate logistic regression analysis was performed to identify factors independently associated with cardiac events. The additive predictability of RCRI for the Model for End-Stage Liver Disease (MELD) score was assessed using receiver operating characteristic curve analysis. RESULTS Forty-four (3.1%) cardiac events occurred within 30 days after surgery. Both the MELD score (adjusted odds ratio [aOR], 1.05; P = .005) and RCRI (aOR, 4.35; P < .001 for RCRI score 2; aOR, 6.27; P = .009 for RCRI score 3 compared with RCRI score 1) independently predicted postoperative 30-day cardiac events. The model with MELD score plus RCRI was significantly more predictive for postoperative 30-day cardiac events than the model with MELD score alone (C-statistics 0.800 vs 0.757; P = .030). CONCLUSIONS For preoperative risk stratification, RCRI showed additive value to MELD score in predicting postoperative 30-day cardiac events after LT.

Abstract
OBJECTIVES We investigated late mortality causes and risk factors in patients who were undergoing deceased-donor liver transplant. MATERIALS AND METHODS Patients who had deceased-donor liver transplant from February 1997 to June 2014 in the hepatopancreaticobiliary surgery and liver transplant unit at Dokuz Eylul University Hospital were analyzed. Inclusion criteria were patients over 18 years of age and who survived more than 1 year after liver transplant. Causes of mortality and related risk factors after the first year were analyzed. RESULTS Of the 157 included patients, 102 patients (72%) received transplant procedures for hepatitis B and C secondary to chronic liver disease. Mean follow-up was 89.85 months (range, 14.4-240 months). Of 157 patients, 20 patients (12.7%) died: 12 patients (60%) died during posttransplant years 2-5 and 8 patients (40%) died after 5 years. Causes of death included malignancy in 8 patients (40%), recurrent hepatitis C infection in 3 patients (15%), infection in 3 patients (15%), coronary artery disease in 2 patients (10%), graft rejection in 2 patients (10%), and biliary complications in 2 patients (10%). Univariate analyses showed that long-term survival was significantly lower in patients older than 50 years (P = .001), when there was presence of hepatocellular carcinoma (P = .011), and when donor age was higher than 38 years (P = .045). Multivariate analyses identified recipient age (P = .007) and presence of hepatocellular carcinoma (P = 0.033) as factors that reduced long-term survival. CONCLUSIONS The main causes of late mortality in liver transplant are malignancy, recurrence of hepatitis C, infection, coronary artery disease, graft rejection, and biliary complications. Advanced age and hepatocellular carcinoma are independent risk factors that increase late mortality.

Abstract
Cancer remains one of the most serious long-term complications after liver transplantation (LT). Data for all adult LT patients between 1982 and 2013 were extracted from the Nordic Liver Transplant Registry. Through linkage with respective national cancer-registry data, we calculated standardized incidence ratios (SIRs) based on country, sex, calendar time, and age-specific incidence rates. Altogether 461 cancers were observed in 424 individuals of the 4246 LT patients during a mean 6.6-year follow-up. The overall SIR was 2.22 (95% confidence interval [CI], 2.02-2.43). SIRs were especially increased for colorectal cancer in recipients with primary sclerosing cholangitis (4.04) and for lung cancer in recipients with alcoholic liver disease (4.96). A decrease in the SIR for cancers occurring within 10 years post-LT was observed from the 1980s: 4.53 (95%CI, 2.47-7.60), the 1990s: 3.17 (95%CI, 2.70-3.71), to the 2000s: 1.76 (95%CI, 1.51-2.05). This was observed across age- and indication-groups. The sequential decrease for the SIR of non-Hodgkin lymphoma was 25.0-12.9-7.53, and for nonmelanoma skin cancer 80.0-29.7-10.4. Cancer risk after LT was found to be decreasing over time, especially for those cancers that are strongly associated with immunosuppression. Whether immunosuppression minimization contributed to this decrease merits further study.

Abstract
AIM To validate intracellular cytokine production functional assay as means of cell-mediated immunity monitoring of post-transplant patients with opportunistic infection (OI).
METHODS Intracellular cytokine-producing CD4+ and CD8+ T-cell monitoring was carried out in 30 liver transplant (LTr) and 31 kidney transplant (KTr) recipients from 2010 to 2012. Patients were assessed in our Department of Immunology at the Clinical University ‘Hospital Virgen de la Arrixaca-IMIB’ in Murcia, Spain for one year following transplantation. FACS Canto II flow cytometer was employed to quantify the intracellular production of IL-17, IFNγ and IL-10 cytokines on stimulated CD4+CD69+ and CD8+CD69+ T cells and BD FACS DIVA v.6 software was used to analysed the data. Statistical analysis was carried out using SPSS 22.0.
RESULTS LTr with OI had significantly lower % of CD8+CD69+IFNγ+ T cells at 60 (7.95 ± 0.77 vs 26.25 ± 2.09, P < 0.001), 90 (7.47 ± 1.05 vs 30.34 ± 3.52, P < 0.001) and 180 (15.31 ± 3.24 vs 24.59 ± 3.28, P = 0.01) d post-transplantation. Higher % of CD4+CD69+IL-10+ as well as CD4+CD69+IL-17+ T cells were yet reported at 30 (14.06 ± 1.65 vs 6.09 ± 0.53, P = 0.0007 and 4.23 ± 0.56 vs 0.81 ± 0.14, P = 0.005; respectively), 60 (11.46 ± 1.42 vs 4.54 ± 0.91, P = 0.001 and 4.21 ± 0.59 vs 1.43 ± 0.42, P = 0.03; respectively) and 90 d (16.85 ± 1.60 vs 4.07 ± 0.63, P < 0.001 and 3.97 ± 0.43 vs 0.96 ± 0.17, P = 0.001). Yet, KTr with OI had significantly lower percentage of CD4+CD69+IFNγ+ at 30 (11.80 ± 1.59 vs 20.64 ± 3.26, P = 0.035), 60 (11.19 ± 1.35 vs 15.85 ± 1.58, P = 0.02), 90 (11.37 ± 1.42 vs 22.99 ± 4.12, P = 0.028) and 180 (13.63 ± 2.21 vs 21.93 ± 3.88, P = 0.008) d post-transplantation as opposed to CD4+CD69+IL-10+ and CD8+CD69+IL-10+ T cells which percentages were higher at 30 (25.21 ± 2.74 vs 8.54 ± 1.64, P < 0.001 and 22.37 ± 1.35 vs 17.18 ± 3.54, P = 0.032; respectively), 90 (16.85 ± 1.60 vs 4.07 ± 0.63, P < 0.001 and 23.06 ± 2.89 vs 10.19 ± 1.98, P = 0.002) and 180 (21.81 ± 1.72 vs 6.07 ± 0.98, P < 0.001 and 19.68 ± 2.27 vs 10.59 ± 3.17, P = 0.016) d post-transplantation. The auROC curve model determined the most accurate cut-off values to stratify LTr and KTr at high risk of OI and Cox Regression model confirmed these biomarkers as the most significant risk factors to opportunistic infection.
CONCLUSION Post-transplant percentages of T-cell subsets differed significantly amongst infected- and non-infected-LTr and -KTr and yet this imbalance was found to contribute towards a worst clinical outcome.

Abstract
The liver exhibits intrinsic immune tolerogenic properties that contribute to a unique propensity toward spontaneous acceptance when transplanted, both in animal models and in humans. Thus, in contrast to what happens after transplantation of other solid organs, several years following liver transplantation a significant subset of patients are capable of maintaining normal allograft function with histological integrity in the absence of immunosuppressive drug treatment. Significant efforts have been put into identifying sensitive and specific biomarkers of tolerance in order to stratify liver transplant recipients according to their need for immunosuppressive medication and their likelihood of being able to completely discontinue it. These biomarkers are currently being validated in prospective clinical trials of immunosuppression withdrawal both in Europe and in the United States. These studies have the potential to transform the clinical management of liver transplant recipients by mitigating, at least in part, the burden of lifelong immunosuppression.

Abstract
Liver transplantation (LT) is a unique surgical procedure that has major hemodynamic and cardiovascular implications. Recently, there has been significant interest focused on cardiovascular issues that affect LT patients in all phases of the perioperative period. The preoperative cardiac evaluation is a major step in the selection of LT candidates. LT candidates are aging in concordance with the general population; cardiovascular disease and their risk factors are highly associated with older age. Underlying cardiovascular disease has the potential to affect outcomes in LT patients and has a major impact on candidate selection. The prolonged hemodynamic and metabolic instability during LT may contribute to adverse outcomes, especially in patients with underlying cardiovascular disease. Cardiovascular events are not unusual during LT; transplant anesthesiologists must be prepared for these events. Advanced cardiovascular monitoring techniques and treatment modalities are now routinely used during LT. Postoperative cardiovascular complications are common in both the early and late posttransplant periods. The impact of cardiac complications on posttransplant mortality is well recognized. Emerging knowledge regarding cardiovascular disease in LT patients and its impact on posttransplant outcomes will have an important role in guiding the future perioperative management of LT patients.

High serum soluble CD40L levels previously to liver transplantation in patients with hepatocellular carcinoma are associated with mortality at one year. J Crit Care 2017; 43:316-320. [PMID: 29020665 DOI: 10.1016/j.jcrc.2017.09.032] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/25/2017] [Revised: 08/29/2017] [Accepted: 09/15/2017] [Indexed: 12/17/2022]
Abstract
PURPOSE CD40L and its soluble form (sCD40L) are proteins of the tumor necrosis factor superfamily (TNFSF) that exhibit prothrombotic and proinflammatory properties when binding to CD40, which is a cell surface receptor of the tumor necrosis factor receptor superfamily (TNFRSF). High circulating levels of sCD40L have been associated with poor prognosis in patients with hepatocellular carcinoma (HCC). However, it is unknown whether there is an association between circulating sCD40L levels and survival in patients with HCC underwent to liver transplantation (LT), and this was the objective of that study. METHODS Serum sCD40L levels were measured in a total of 139 patients before LT (124 survivors at 1year of LT and 15 non-survivors). The end-point study was 1year survival after liver LT. RESULTS We found that 1-year non-surviving patients showed higher serum sCD40L levels than survivor patients (p=0.02). We found in logistic regression analysis that serum sCD40L levels higher than 321pg/mL (Odds Ratio=6.86; 95% confidence interval=2.06-22.76; p=0.002) and age of LT deceased donor were associated with death at 1year. CONCLUSIONS The new finding of our study was that high serum sCD40L levels previously to LT in patients with HCC are associated with higher mortality at one year.

Abstract
INTRODUCTION Acute and chronic graft rejection continues to be an important problem after solid organ transplantation. With the introduction of potent immunosuppressive agents such as calcineurin inhibitors, the risk of rejection has been significantly reduced. However, the adverse effects of life-long immunosuppression remain a concern, and there exist a fine balance between over-immunosuppression and risk of rejection. Areas covered: In this review, the current standard of care in immunosuppressive therapy, including the use of steroids, calcineurin inhibitors, mycophenolate prodrugs and mammalian target of rapamycin inhibitors, will be discussed. Newer immunosuppressive agents showing promising early data after liver and kidney transplantation will also be explored. Expert Opinion: Currently, calcineurin inhibitors continue to be a vital component of immunosuppressive therapy after solid organ transplantation. Although minimization and avoidance strategies have been developed, the ultimate goal of inducing tolerance remains elusive. Newer emerging agents should have potent and specific immunosuppressive activity, with minimal associated side effects. An individualized approach should be adopted to tailor immunosuppression according to the different needs of recipients.

Practical Recommendations for Long-term Management of Modifiable Risks in Kidney and Liver Transplant Recipients: A Guidance Report and Clinical Checklist by the Consensus on Managing Modifiable Risk in Transplantation (COMMIT) Group. Transplantation 2017; 101:S1-S56. [PMID: 28328734 DOI: 10.1097/tp.0000000000001651] [Citation(s) in RCA: 181] [Impact Index Per Article: 25.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 12/16/2022]
Abstract
Short-term patient and graft outcomes continue to improve after kidney and liver transplantation, with 1-year survival rates over 80%; however, improving longer-term outcomes remains a challenge. Improving the function of grafts and health of recipients would not only enhance quality and length of life, but would also reduce the need for retransplantation, and thus increase the number of organs available for transplant. The clinical transplant community needs to identify and manage those patient modifiable factors, to decrease the risk of graft failure, and improve longer-term outcomes.COMMIT was formed in 2015 and is composed of 20 leading kidney and liver transplant specialists from 9 countries across Europe. The group's remit is to provide expert guidance for the long-term management of kidney and liver transplant patients, with the aim of improving outcomes by minimizing modifiable risks associated with poor graft and patient survival posttransplant.The objective of this supplement is to provide specific, practical recommendations, through the discussion of current evidence and best practice, for the management of modifiable risks in those kidney and liver transplant patients who have survived the first postoperative year. In addition, the provision of a checklist increases the clinical utility and accessibility of these recommendations, by offering a systematic and efficient way to implement screening and monitoring of modifiable risks in the clinical setting.

Abstract
BACKGROUND Long-term morbidity and mortality in liver transplant recipients is frequently secondary to immunosuppression toxicity. However, data are scarce regarding immunosuppression minimization in clinical practice. MATERIAL AND METHODS In this cross-sectional, multicenter study, we reviewed the indications of immunosuppression minimization (defined as tacrolimus levels below 5 ng/mL or cyclosporine levels below 50 ng/mL) among 661 liver transplant recipients, as well as associated factors and the effect on renal function. RESULTS Fifty-three percent of the patients received minimized immunosuppression. The median time from transplantation to minimization was 32 months. The most frequent indications were renal insufficiency (49%), cardiovascular risk (19%), de novo malignancy (8%), and cardiovascular disease (7%). The factors associated with minimization were older age at transplantation, longer post-transplant follow-up, pre-transplant diabetes mellitus and renal dysfunction, and the hospital where the patients were being followed. The patients who were minimized because of renal insufficiency had a significant improvement in renal function (decrease of the median serum creatinine level, from 1.50 to 1.34 mg/dL; P=0.004). Renal function significantly improved in patients minimized for other indications, too. In the long term, glomerular filtration rate significantly decreased in non-minimized patients and remained stable in minimized patients. CONCLUSIONS Immunosuppression minimization is frequently undertaken in long-term liver transplant recipients, mainly for renal insufficiency. Substantial variability exists regarding the use of IS minimization among centers.

Abstract
The introduction of anti-calcineurin-based therapies has led to an increase in the one-year survival as well as graft function rates in patients undergoing solid organ transplantation (SOT). Nonetheless, early cellular acute rejection (EAR) incidence still remains a major challenge that irrevocably heads to poor outcomes. The mechanisms underlying CD4 T cell activation in SOT are still under research. In this sense, CD28 co-stimulatory molecule plays a pivotal role triggering CD4 T cell activation as well as survival maintenance. Previous own studies stated the role that CD4+CD28+ circulating T lymphocytes plays before and during EAR episodes. We assessed the percentage as well as the absolute number of CD28 molecules on CD4+ T cells as predictive surrogate biomarker of EAR in a prospective cohort of liver and kidney transplant recipients. Quantitative analysis of CD28 was carried out on whole peripheral blood samples by flow cytometry. Decreased pre-transplant expression of CD28 was associated with EAR in both study groups. Furthermore, the expression of CD28 within the rejected group, experimented an up-regulation upon transplantation. These preliminary results suggest that patients undergoing liver or kidney transplant can be stratified at high risk of EAR according to their CD28 molecule expression on peripheral CD4+ T lymphocytes.

A novel immune function biomarker identifies patients at risk of clinical events early following liver transplantation. Liver Transpl 2017; 23:487-497.

Abstract
Balancing immunosuppression after liver transplant is difficult, with clinical events common. We investigate whether a novel immune biomarker based on a laboratory platform with widespread availability that measures interferon γ (IFNγ) after stimulation with a lyophilized ball containing an adaptive and innate immune stimulant can predict events following transplantation. A total of 75 adult transplant recipients were prospectively monitored in a blinded, observational study; 55/75 (73.3%) patients experienced a total of 89 clinical events. Most events occurred within the first month. Low week 1 results were significantly associated with risk of early infection (area under the receiver operating characteristic curve [AUROC], 0.74; P = 0.008). IFNγ ≤ 1.30 IU/mL (likelihood ratio positive, 1.93; sensitivity, 71.4%; specificity, 63.0%) was associated with the highest risk for infection with minimal rejection risk. Nearly half the cohort (27/60, 45.0%) expressed IFNγ ≤ 1.30 IU/mL. Moreover, an elevated week 1 result was significantly associated with the risk of rejection within the first month after transplant (AUROC, 0.77; P = 0.002), but no episodes of infection. On multivariate logistic regression, IFNγ ≥ 4.49 IU/mL (odds ratio, 4.75) may be an independent predictor of rejection (P = 0.05). In conclusion, low IFNγ suggesting oversuppression is associated with infections, whereas high IFNγ indicating undersuppression is associated with rejection. This assay offers the potential to allow individualization and optimization of immunosuppression that could fundamentally alter the way patients are managed following transplantation.

Abstract
BACKGROUND As more patients achieve long-term survival, it has become important to understand mortality in liver transplantation (LT) recipients. METHODS We conducted retrospective reviews of long-term outcome in two adult LT cohorts: 85 031 in the United Network for Organ Sharing (UNOS) database and 1458 transplanted at the University of Wisconsin (UW). RESULTS During median follow-up of 3.2 years (UNOS) and 6.6 years (UW), 35.1% of UNOS patients and 44.2% of UW patients died; 43.1% of all UNOS deaths occurred in year 1 compared to 25.1% in the UW cohort. Deaths due to infection (other than viral hepatitis) or cardiovascular (CV) causes were most frequent in year 1 in both cohorts and then persisted at lower rates. In contrast, death from malignancy increased after year 1 to peak in years 1-5. Deaths due to rejection, hepatitis, or graft failure were infrequent. In the UW cohort, de novo malignancy was more common than recurrent tumor and correlated with smoking history. CONCLUSIONS A coordinated holistic approach that focuses on limiting immunosuppression, infection, risky behaviors, and CV risks, while screening for cancer, is needed to extend the healthy lives of LT recipients.

Abstract
BACKGROUND Autoimmune liver diseases (AILD) constitute the third most common indication for liver transplantation (LT) worldwide. Outcomes post LT are generally good but recurrent disease is frequently observed. AIMS To describe the frequency and risk factors associated with recurrent AILD post-LT and provide recommendations to reduce the incidence of recurrence based on levels of evidence. METHODS A systematic review was performed for full-text papers published in English-language journals, using the keywords 'autoimmune hepatitis (AIH)', 'primary biliary cholangitis and/or cirrhosis (PBC)', 'primary sclerosing cholangitis (PSC)', 'liver transplantation' and 'recurrent disease'. Management strategies to reduce recurrence after LT were classified according to grade and level of evidence. RESULTS Survival rates post-LT are approximately 90% and 70% at 1 and 5 years and recurrent disease occurs in a range of 10-50% of patients with AILD. Recurrent AIH is associated with elevated liver enzymes and IgG before LT, lymphoplasmacytic infiltrates in the explants and lack of steroids after LT (Grade B). Tacrolimus use is associated with increased risk; use of ciclosporin and preventive ursodeoxycholic acid with reduced risk of PBC recurrence (all Grade B). Intact colon, active ulcerative colitis and early cholestasis are associated with recurrent PSC (Grade B). CONCLUSIONS Recommendations based on grade A level of evidence are lacking. The need for further study and management includes active immunosuppression before liver transplantation and steroid use after liver transplantation in autoimmune hepatitis; selective immunosuppression with ciclosporin and preventive ursodeoxycholic acid treatment for primary biliary cholangitis; and improved control of inflammatory bowel disease or even colectomy in primary sclerosing cholangitis.

Abstract
Long-term IS in transplant patients has significant morbidity, poorer quality of life, and substantial economic costs. TOL, defined as graft acceptance without functional impairment in the absence of IS, has been achieved in some pediatric LT recipients. Using mass cytometry, peripheral blood immunotyping was performed to characterize differences between tolerant patients and patients who are stable on single-agent IS. Single-cell mass cytometry was performed using blood samples from a single-center pediatric LT population of operationally tolerant patients to comprehensively characterize the immune cell populations in the tolerant state compared with patients on chronic low-dose IS. Specific T-cell populations of interest were confirmed by flow cytometry. This high-dimensional phenotypic analysis revealed distinct immunoprofiles between transplant populations as well as a CD4+ TOT (CD4+ CD5+ CD25+ CD38-/lo CD45RA) that correlates with tolerance in pediatric LT recipients. In TOL patients, the TOT was significantly increased as compared to patients stable on low levels of IS. This TOT cell was confirmed by flow cytometry and is distinct from classic Treg cells. These results demonstrate the power of mass cytometry to discover significant immune cell signatures that have diagnostic potential.

Prognostic Value of Serum Caspase-Cleaved Cytokeratin-18 Levels before Liver Transplantation for One-Year Survival of Patients with Hepatocellular Carcinoma. Int J Mol Sci 2016; 17:ijms17091524.

Abstract
Cytokeratin (CK)-18 is the major intermediate filament protein in the liver and during hepatocyte apoptosis is cleaved by the action of caspases; the resulting fragments are released into the blood as caspase-cleaved cytokeratin (CCCK)-18. Higher circulating levels of CCCK-18 have been found in patients with hepatocellular carcinoma (HCC) than in healthy controls and than in cirrhotic patients. However, it is unknown whether serum CCCK-18 levels before liver transplantation (LT) in patients with HCC could be used as a prognostic biomarker of one-year survival, and this was the objective of our study with 135 patients. At one year after LT, non-survivors showed higher serum CCCK-18 levels than survivors (p = 0.001). On binary logistic regression analysis, serum CCCK-18 levels >384 U/L were associated with death at one year (odds ratio = 19.801; 95% confidence interval = 5.301–73.972; p < 0.001) after controlling for deceased donor age. The area under the receiver operating characteristic (ROC) curve of serum CCCK-18 levels to predict death at one year was 77% (95% CI = 69%–84%; p < 0.001). The new finding of our study was that serum levels of CCCK-18 before LT in patients with HCC could be used as prognostic biomarker of survival.

Abstract
INTRODUCTION Long-term exposure to calcineurin inhibitor-based immunosuppressant (IS) therapy in liver transplant (LT) recipients is associated with renal complications. In the randomized trial H2304, everolimus + reduced-dose tacrolimus (EVR + rTAC) demonstrated equivalent efficacy and superior renal function compared to standard-dose tacrolimus. METHODS To evaluate the cost-effectiveness of EVR + rTAC vs TAC, in de novo LT patients, a Markov model simulating both liver and kidney function was developed and estimated the long-term outcomes of IS following LT. The analysis used the Italian healthcare payer perspective. RESULTS Patients treated with EVR + rTAC gained on average 1.92 years and 1.62 quality-adjusted life years (QALYs). The incremental cost-effectiveness ratios (ICER) were €35,851 and €42,567 for LY gained and QALY gained, respectively. For the hepatitis-c sub-population, the ICERs decreased to €22,519 and €30,658, respectively. CONCLUSION EVR + rTAC improves survival and quality-of-life and is a cost-effective alternative to calcineurin-inhibitor monotherapy for patients requiring LT.

Abstract
BACKGROUND The non-improvement in >1-year post-liver transplant (LT) survival and diminishing importance of hepatitis C (HCV) with modern antivirals justify identification of early factors predictive of long-term outcome post-LT in HCV-negative recipients. METHODS This nationwide study included all 631 HCV-negative adult patients transplanted in Finland 1982-2013 with at least 1-year graft survival (6311 person-year follow-up). We tested 37 variables, including immunosuppression, for their association with >1-year combined graft loss/mortality, late rejection, cancer, or infections. RESULTS Significant multivariate predictors of graft loss/mortality were male gender (HR 2.40, P = 0.001), pretransplant hepatocellular (HR 2.92, P = 0.001) or biliary cancer (HR 12.7, P < 0.001), glomerular filtration rate (HR 0.89, P = 0.002), hypertension (HR 0.44, P < 0.001), early posttransplant infections (HR 1.52-1.67, P = 0.007-0.03), and alkaline phosphatase (ALP) (HR 1.05, P < 0.001). Elevated ALP at 1 year, affecting 30% of patients, predicted both graft loss and rejection, independent of immunologic stability, etiology, and immunosuppression type. Area under the curve of ALP in predicting graft loss from rejection was 0.81 (95% CI 0.71-0.90) and 0.85 (95% CI 0.72-0.98, P = 0.001) among patients under 50. Among immunologically stable patients who underwent transplantation after 2000, antimetabolite use at 1 year was associated with improved survival (P = 0.04), specifically in the subgroup with native-liver hepatocellular or biliary cancer (P = 0.02). CONCLUSIONS Easily measurable, widely available, and noninvasive factors known at 1 year post-LT can help stratify patients according to their long-term risk of death or graft loss, and thus facilitate a personalization of long-term follow-up. ALP deserves routine monitoring, and the cause for an elevated ALP should be sought.

The predictors of post-transplant coronary events among liver transplant recipients. Hepatol Int 2016; 10:974-982.

Abstract
BACKGROUND/PURPOSE Cardiac morbidities can occur during the peri- and post-liver transplant (LT) period, affecting the long-term survival. The purpose of this study was to identify the potential factors that predict a coronary event post-transplantation. METHODS Medical records of patients who underwent liver transplantation at Johns Hopkins Hospital between 2009 and 2013 were retrospectively reviewed. We looked at pre-liver transplant cardiac risk factors and the diagnostic tests utilized for coronary artery disease screening. Patients with and without post-liver transplant coronary events were compared. RESULTS There were a total of 146 patients with a mean age at LT of 55.3 years. The prevalence of hypertension, tobacco use and diabetes within the patient population was 61.6 % (n = 90), 39 % (n = 57) and 37.6 % (n = 55), respectively. There were 29 deaths and 30 coronary events over a median follow-up period of 1.75 years. Age at the time of liver transplant was predictive of coronary event (OR 1.11, CI 1.01-1.20). The 1-year survival in patients with a coronary event was 47 versus 94 % in patients without a coronary event. The combined use of a dobutamine stress echocardiogram and coronary artery calcium score predicted a coronary event with a sensitivity of 62.5 % and specificity of 66.7 %. CONCLUSION In conclusion, LT recipients with cardiac events had limited survival as compared to the cohort without coronary events. Identification of such patients with noninvasive screening may provide a practical alternative to an invasive cardiac workup. Further improvement in screening strategies may minimize the liver transplant cardiac morbidity.

Hepatic Infiltrates in Operational Tolerant Patients After Liver Transplantation Show Enrichment of Regulatory T Cells Before Proinflammatory Genes Are Downregulated.

Abstract
Immunosuppression can be discontinued from selected and stable patients after liver transplantation resulting in spontaneous operational tolerance (SOT), although the underlying mechanisms remain elusive. Thus, we analyzed serial liver biopsy specimens from adult liver recipients enrolled in a prospective multicenter immunosuppression withdrawal trial that used immunophenotyping and transcriptional profiling. Liver specimens were collected before the initiation of weaning, at the time of rejection, or at 1 and 3 years after complete drug discontinuation. Unexpectedly, the tolerated grafts developed portal tract expansion with increased T cell infiltration after immunosuppression withdrawal. This was associated with transient and preferential accumulation of CD4(+) FOXP3(+) cells and a trend toward upregulation of immune activation and regulatory genes, without signs of rejection. At the same time, no markers of endothelial damage or activation were noted. Portal infiltrates persisted at 3 years but were characterized by decreased expression of genes associated with chronic immunological damage. Further, SOT was not associated with a progressive liver fibrosis up to 5 years. These data suggest that SOT involves several mechanisms: a long-lasting local immune cell persistence with a transient regulatory T cells accumulation followed by a downregulation of immune-activated genes over years. These results have important implications for designs and follow-up of weaning trials.

Abstract
Liver transplantation has been the treatment of choice for end-stage liver disease since 1983. Cancer has emerged as a major long-term cause of death for liver transplant recipients. Many retrospective studies that have explored standardized incidence ratio have reported increased rates of solid organ cancers post-liver transplantation; some have also studied risk factors. Liver transplantation results in a two to five-fold mean increase in the rate of solid organ cancers. Risk of head and neck, lung, esophageal, cervical cancers and Kaposi’s sarcoma is high, but risk of colorectal cancer is not clearly demonstrated. There appears to be no excess risk of developing breast or prostate cancer. Environmental risk factors such as viral infection and tobacco consumption, and personal risk factors such as obesity play a key role, but recent data also implicate the role of calcineurin inhibitors, whose cumulative and dose-dependent effects on cell metabolism might play a direct role in oncogenesis. In this paper, we review the results of studies assessing the incidence of non-skin solid tumors in order to understand the mechanisms underlying solid cancers in post-liver transplant patients and, ultimately, discuss how to prevent these cancers. Immunosuppressive protocol changes, including a calcineurin inhibitor-free regimen, combined with dietary guidelines and smoking cessation, are theoretically the best preventive measures.

New-onset diabetes after liver transplantation and its impact on complications and patient survival. J Diabetes 2015; 7:881-90.

Abstract
BACKGROUND The aim of the present study was to investigate the incidence and risk factors of new-onset diabetes after transplantation (NODAT) in liver transplant recipients and the influence of NODAT on complications and long-term patient survival. METHODS We examined 438 patients who underwent liver transplantation between April 2001 and December 2008 and were not diabetic before transplantation. RESULTS The mean (± SD) follow-up duration was 2.46 ± 1.62 years. The incidence of NODAT 3, 6, 9, 12, 36, and 60 months after transplantation was 44.24%, 25.59%, 23.08%, 25.17%, 17.86%, and 18.18%, respectively. Multifactor analysis indicated that preoperative fasting plasma glucose (FPG) levels and donor liver steatosis were independent risk factors for NODAT, whereas administration of an interleukin-2 receptor (IL-2R) antagonist reduced the risk of NODAT. Compared with the no NODAT group (N-NODAT), the NODAT group had a higher rate of sepsis and chronic renal insufficiency. Mean survival was significantly longer in the N-NODAT than NODAT group. Cox regression analysis showed that pre- and/or postoperative FPG levels, tumor recurrence or metastasis, and renal insufficiency after liver transplantation were independent risk factors of mortality. Pulmonary infection or multisystem failure were specific causes of death in the NODAT group, whereas patients in both groups died primarily from tumor relapse or metastasis. CONCLUSIONS Preoperative FPG levels and donor liver steatosis were independent risk factors for NODAT, whereas administration of an IL-2R antagonist reduced the risk of NODAT. Patients with NODAT had reduced survival and an increased incidence of sepsis and chronic renal insufficiency. Significant causes of death in the NODAT group were pulmonary infection and multisystem failure.
