Abstract
INTRODUCTION Initial allograft function determines the patient's immediate prognosis in pediatric liver transplantation. Ischemia-reperfusion injuries play a role in initial poor graft function (IPGF). In animal studies, preconditioning with inhaled anesthetic agents has demonstrated a protective effect on the liver. In humans, the few available studies are conflicting. This study assesses the association between the hypnotic agent used to maintain anesthesia during hepatectomy in living donors and the occurrence of IPGF after pediatric transplantation. METHODS We conducted a single-center retrospective analysis of children who received a living donor liver transplant (LDLT) between 2010 and 2019. We analyzed the incidence of EAD according to the hypnotic agent used to maintain general anesthesia during donor hepatectomy. RESULTS We included 183 pairs of patients (living donors-recipients). The anesthetics used in the donor were propofol (n = 85), sevoflurane (n = 69), or propofol with sevoflurane started 30 min before clamping (n = 29). Forty-two children (23%) developed IPGF. After multivariate logistic regression analysis, factors significantly associated with the occurrence of IPGF were the anesthesia maintenance agent used in the donor (p = 0.004), age of the donor (p = 0.03), duration of transplant surgery (p = 0.009), preoperative receiver neutrophil to lymphocyte ratio (p = 0.02), and albumin (p = 0.05). CONCLUSION Significantly fewer children who received a graft from a donor in whom only sevoflurane was used to maintain anesthesia developed IPGF. Although additional research is needed, this preconditioning strategy may provide an option to prevent IPGF after living liver donation.

Abstract
BACKGROUND Considering the importance of the inflammatory status of recipients on outcomes following liver transplantation (LT), we investigated the association between C-reactive protein-to-albumin ratio (CAR) and one-year mortality following LT and compared it with other parameters reflecting patients' underlying inflammatory status. METHODS A total of 3,614 consecutive adult LT recipients were retrospectively evaluated. Prognostic parameters were analyzed using area under the receiver operating characteristic curve (AUROC) analysis, and subsequent cutoffs were derived. For survival analysis, Cox proportional hazards and Kaplan-Meier analyses were performed. RESULTS The AUROC for CAR to predict one-year mortality after LT was 0.68 (0.65-0.72), which was the highest compared with other inflammatory parameters, with the best cutoff of 0.34. A CAR ≥ 0.34 was associated with a significantly higher one-year mortality rate (13.3% vs. 5.8 %, log-rank P < 0.001) and overall mortality rate (24.5% vs. 12.9%, log-rank P = 0.039). A CAR ≥ 0.34 was an independent predictor of one-year mortality (hazard ratio, 1.40 [1.03-1.90], P = 0.031) and overall mortality (hazard ratio 1.39 [1.13-1.71], P = 0.002) after multivariable adjustment. CONCLUSIONS Preoperative CAR (≥ 0.34) was independently associated with a higher risk of one-year and overall mortality after LT. This may suggest that CAR, a simple and readily available biomarker, maybe a practical index that may assist in the risk stratification of liver transplantation outcomes.

Abstract
BACKGROUND Maximizing patient and allograft survival after liver transplant (LT) is important from both a patient care and organ utilization perspective. Although individual studies have addressed the effects of short-term post-LT complications on a limited scale, there has not been a systematic review of the literature formally assessing the potential effects of early complications on long-term outcomes. OBJECTIVES To identify whether short-term complications after LT affect allograft and overall survival, to identify short-term complications of particular clinical interest and significance, and to provide recommendations to improve post-LT graft and patient survival. DATA SOURCES Ovid MEDLINE, Embase, Scopus, Google Scholar, and Cochrane Central. METHODS A systematic review following PRISMA guidelines and recommendations using the GRADE approach derived from an international expert panel. RESULTS The literature review and analysis provided show that short-term complications have a large impact on allograft and patient survival after LT. The complications with the strongest effect on survival are acute kidney injury (AKI), biliary complications, and early allograft dysfunction (EAD). CONCLUSION This panel recommends taking measures to reduce the risk and incidence of short-term complications post-LT. Clinicians should pay particular attention to preventing or ameliorating AKI, biliary complications, and EAD (Quality of evidence; Moderate | Grade of Recommendation; Strong).

Interleukin-27 in liver xenotransplantation: A rational target to mitigate ischemia reperfusion injury and increase xenograft survival. Transplant Rev (Orlando) 2021; 36:100674.

Abstract
Transplantation of xenogeneic organs is an attractive solution to the existing organ shortage dilemma, thus, securing a clinically acceptable prolongation of xenograft survival is an important goal. In preclinical transplantation models, recipients of liver, kidney, heart, or lung xenotransplants demonstrate significant graft damages through the release of pro-inflammatory molecules, including the C-reactive protein, cytokines, and histone-DNA complexes that all foster graft rejection. Recent studies have demonstrated that mitigation of ischemia reperfusion injury (IRI) greatly improves xenograft survival. Organ IRI develops primarily on a complex network of cytokines and chemokines responding to molecular cues from the graft milieu. Among these, interleukin 27 (IL-27) plays an immunomodulatory role in IRI onset due to graft environment-dependent pro- and anti- inflammatory activities. This review focuses on the impact of IL-27 on IRI of liver xenotransplants and provides insights on the function of IL-27 that could potentially guide genetic engineering strategies of donor pigs and/or conditioning of organs prior to transplantation.

Abstract
BACKGROUND AND AIMS Liver metastasis is a frequent occurrence in patients with colorectal cancer (CRC), with 15%-25% of CRC patients having liver metastases at the time of initial diagnosis. Specifically, some regional-stage patients with mild symptoms (stage 1 or 2) will also advance to liver metastases rapidly, even if the CRC lesion in situ is resected in time. Nevertheless, the precise mechanism of liver metastasis is still unclear. APPROACH AND RESULTS Fresh tumor tissues from patients with CRC, adjacent noncancerous tissues, and colorectal adenoma tissues were subjected to microarray analysis to identify differentially expressed microRNA. Exosomes from human serum and cell culture medium were separated, quantitated, and verified by transmission electronic microscopy and Zetasizer Nano. Luciferase reporter assay, real-time quantitative PCR, western blot, immunoprecipitation, chromatin and re-chromatin immunoprecipitation, migration and invasion assay, PDX mouse model, flow cytometry, immunohistochemistry, and immunofluorescence staining were employed to explore the regulation among CRC liver metastases, immunosuppression, and cell adhesion. In this study, we demonstrated that the hypoxic microenvironment in primary CRC lesions boosted exosome release, selectively initiated favorable premetastatic niche formation in the liver but not in other organs. Mechanistically, Kupffer cells (KCs) can phagocytose exosomes containing highly expressed miR-135a-5p from the blood circulation into the liver. Exosomal miR-135a-5p initiated the large tumor suppressor kinase 2-yes-associated protein-matrix metalloproteinase 7 axis to promote the occurrence of CRC liver metastasis, and cluster of differentiation 30-TNF receptor-associated factor 2-p65-mediated immunosuppression signaling also contributed to this process. CONCLUSIONS Hypoxia-induced exosomal miR-135a-5p correlates with the development, clinical severity, and prognosis of CRC liver metastases through the premetastatic niche; and our findings revealed that miR-135a-5p might be a promising target in halting CRC liver metastases.

Abstract
PURPOSE To evaluate the role of two-dimensional shear wave elastography (2D SWE) in assessing graft quality before liver transplantation and the relationship between donor liver stiffness (LS) and early allograft dysfunction (EAD) after transplantation. METHODS Eighty-three donors from January 2018 to December 2018 were involved in this prospective study. Liver stiffness measurements (LSMs) were performed using 2D SWE. The differences in LS values between discarded and transplanted grafts were analyzed. The relationship of donor LS with recipient EAD was also evaluated. RESULTS Our results suggest that the donor LS values were higher in discarded grafts than in transplanted grafts (24.0 ± 10.9 kPa vs 10.0 ± 2.6 kPa, p < 0.001). LSM failed in one donor. According to multivariate logistic regression analysis, the donor LS values ≥10.9 kPa (odds ratio [OR] 4.042, 95% confidence interval [CI] 1.133-14.421, p = 0.031), BMI (OR 1.287, 95% CI 1.025-1.616, p = 0.030) and INR (OR 6.703, 95% CI 1.338-33.589, p = 0.021) were independently associated with EAD. CONCLUSION Donor LSM conducted by 2D SWE might represent an effective quantitative method to evaluate graft quality. Donor LS might predict recipient EAD after liver transplantation.

Abstract
BACKGROUND Prediction of outcome after liver transplantation (LT) is limited by the lack of robust predictors of graft failure. In this prospective study, we aimed to define a serum glycomic signature in the first week after LT that is associated with graft loss at 3 mo after LT. METHODS Patients were included between January 1, 2011, and February 28, 2017. Glycomic analysis was performed using DNA sequencer-associated fluorophore-associated capillary electrophoresis on a serum sample 1 wk after LT. Making use of Lasso regression, an optimal glycomic signature was identified associated with 3-mo graft survival. RESULTS In this cohort of 131 patients, graft loss at 3 mo occurred in 14 patients (11.9%). The optimal mode, called the GlycoTransplantTest, yielded an area under the curve of 0.95 for association with graft loss at 3 mo. Using an optimized cutoff for this biomarker, sensitivity was 86% and specificity 89%. Negative predictive value was 98%. Odds ratio for graft loss at 3 mo was 70.211 (P < 0.001; 95% confidence interval, 10.876-453.231). CONCLUSIONS A serum glycomic signature is highly associated with graft loss at 3 mo. It could support decision making in early retransplantation.

Sci Rep 2019; 9:20096. [PMID: 31882790 PMCID: PMC6934543 DOI: 10.1038/s41598-019-56543-3] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/05/2019] [Accepted: 12/13/2019] [Indexed: 12/31/2022] Open
Abstract
Fluid overload (FO) has been shown to adversely affect multiple organs and survival in critically ill patients. Liver transplantation (LT) carries the risk of massive transfusion, which frequently results in FO. We investigated the association of postoperative weight gain with graft failure, early allograft dysfunction (EAD), and overall mortality in LT. 1833 living donor LT (LDLT) recipients were retrospectively analysed. Patients were divided into 2 groups according to postoperative weight gain (<3% group [n = 1391] and ≥3% group [n = 442]) by using maximally selected log-rank statistics for graft failure. Multivariate Cox and logistic regression analyses were performed. The ≥3% group was associated with graft failure (adjusted HR [aHR], 1.763; 95% CI, 1.248–2.490; P = 0.001). When postoperative weight change was used as a continuous variable, the aHR for each 1% increase in postoperative weight was 1.045 (95% CI, 1.009–1.082; P = 0.015). In addition, the ≥3% group was associated with EAD (adjusted OR [aOR], 1.553; 95% CI, 1.024–2.356; P = 0.038) and overall mortality (aHR, 1.731; 95% CI, 1.182–2.535; P = 0.005). In conclusion, postoperative weight gain may be independently associated with increased risk of graft failure, EAD, and mortality in LDLT recipients.

Abstract
The major extended donor criteria (maEDC; steatosis >40%, age >65 years, and cold ischemia time >14 h) influence graft and patient outcomes after liver transplantation. Despite organ shortages, maEDC organs are often considered unsuitable for transplantation. We investigated the outcomes of maEDC organ liver transplantation in patients with hepatocellular carcinoma (HCC). Two hundred and sixty-four HCC liver transplant patients were eligible for analysis. Risk factor analysis was performed for early allograft dysfunction; primary nonfunction; 30-day and 90-day graft failure; and 30-day, 90-day, and 1-year patient mortality. One-year graft survival was higher in recipients of no-maEDC grafts. One-year patient survival did not differ between the recipients of no-maEDC and maEDC organs. The univariate and multivariate analyses revealed no association between maEDC grafts and one-year patient mortality. Graft survival differed between the recipients of no-maEDC and maEDC organs after correcting for a laboratory model of end-stage liver disease (labMELD) score with a cut-off value of 20, but patient survival did not. Patient survival did not differ between recipients who did and did not meet the Milan criteria and who received grafts with and without maEDC. Instead of being discarded, maEDC grafts may expand the organ pool for patients with HCC without impairing patient survival or recurrence-free survival.

Abstract
BACKGROUND & AIMS Early allograft dysfunction (EAD) is predictive of poor graft and patient survival following living donor liver transplantation (LDLT). Considering the impact of the inflammatory response on graft injury extent following LDLT, we investigated the association between neutrophil-to-lymphocyte ratio (NLR) and EAD, 1-year graft failure, and mortality following LDLT, and compared it to C-reactive protein (CRP), procalcitonin, platelet-to-lymphocyte ratio and the Glasgow prognostic score. METHODS A total of 1960 consecutive adult LDLT recipients (1531/429 as development/validation cohort) were retrospectively evaluated. Cut-offs were derived using the area under the receiver operating characteristic curve (AUROC), and multivariable regression and Cox proportional hazard analyses were performed. RESULTS The risk of EAD increased proportionally with increasing NLR, and the NLR AUROC was 0.73, similar to CRP and procalcitonin and higher than the rest. NLR ≥ 2.85 (best cut-off) showed a significantly higher EAD occurrence (20.5% vs 5.8%, P < 0.001), higher 1-year graft failure (8.2% vs 4.9%, log-rank P = 0.009) and higher 1-year mortality (7% vs 4.5%, log-rank P = 0.039). NLR ≥ 2.85 was an independent predictor of EAD (odds ratio, 1.89 [1.26-2.84], P = 0.002) after multivariable adjustment, whereas CRP and procalcitonin were not. Increasing NLR was independently associated with higher 1-year graft failure and mortality (both P < 0.001). Consistent results in the validation cohort strengthened the prognostic value of NLR. CONCLUSIONS Preoperative NLR ≥ 2.85 predicted higher risk of EAD, 1-year graft failure and 1-year mortality following LDLT, and NLR was superior to other parameters, suggesting that preoperative NLR may be a practical index for predicting graft function following LDLT.

Evidence for the important role of inflammation in xenotransplantation. JOURNAL OF INFLAMMATION-LONDON 2019; 16:10. [PMID: 31148951 PMCID: PMC6537172 DOI: 10.1186/s12950-019-0213-3] [Citation(s) in RCA: 26] [Impact Index Per Article: 5.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 02/21/2019] [Accepted: 05/02/2019] [Indexed: 12/17/2022]
Abstract
There is increasing evidence of a sustained state of systemic inflammation after pig-to-nonhuman primate (NHP) xenotransplantation (that has been termed systemic inflammation in xenograft recipients [SIXR]). Increases in inflammatory markers, e.g., C-reactive protein, histones, serum amyloid A, D-dimer, cytokines, chemokines, and a decrease in free triiodothyronine, have been demonstrated in the recipient NHPs. The complex interactions between inflammation, coagulation, and the immune response are well-recognized, but the role of inflammation in xenograft recipients is not fully understood. The evidence suggests that inflammation can promote the activation of coagulation and the adaptive immune response, but the exact mechanisms remain uncertain. If prolonged xenograft survival is to be achieved, anti-inflammatory strategies (e.g., the administration of anti-inflammatory agents, and/or the generation of genetically-engineered organ-source pigs that are protected from the effect of inflammation) may be necessary to prevent, control, or negate the effect of the systemic inflammation that develops in xenograft recipients. This may allow for a reduction in the intensity of exogenous immunosuppressive therapy. If immunological tolerance to a xenograft is to be obtained, then control of inflammation may be essential.

Abstract
BACKGROUND There is well-documented systemic inflammatory response in xenograft recipients to the presence of a pig graft. Serum amyloid A (SAA) is an inflammatory marker that is elevated in various pathological states. The assay used to measure it is (i) simple, (ii) relatively inexpensive, and (iii) provides an answer within minutes. METHOD The levels of SAA (n = 11) and C-reactive protein (C-RP) (n = 8) were measured retrospectively in the serum of baboons with pig kidney transplants, who received therapy with an IL-6R inhibitor and a TNF-α antagonist. Immunohistochemistry (IHC) was used to identify amyloid A and C-RP expression in the native livers and deposition in the pig kidney grafts. RESULTS One kidney graft underwent hyperacute rejection, 6 (55%) underwent acute antibody-mediated rejection, 3 baboons (27%) were euthanized for serious systemic infections, and one was euthanized for acute gastric dilatation. The SAA increased temporarily after kidney transplantation, and increased again by the day of euthanasia, indicating moderate (n = 3) or significant (severe) (n = 8) inflammation. In contrast, as the baboons were receiving tocilizumab, C-RP did not increase. There was greater expression of amyloid A in baboon livers (by IHC) than of C-RP (mean OD 53 vs 1, p < 0.01), and greater deposition of amyloid A than C-RP in the pig kidney grafts (mean OD 24 vs 2, p < 0.001). Plasma fibrinogen negatively correlated with the expression of amyloid A in the liver (r = -0.72, p < 0.05). The results of the SAA assay correlated with amyloid A expression in the liver and deposition in the kidney grafts. CONCLUSIONS SAA is a sensitive, but non-specific, marker for inflammation in baboons with pig kidney grafts, and is not affected by therapy that suppresses the response of C-RP. The SAA assay is a rapid, reliable, and relatively inexpensive method of following the inflammatory state of baboons with pig xenografts.

Prevalence of Antiphospholipid Antibody Positivity and Association of Pretransplant Lupus Anticoagulant Positivity With Early Allograft Dysfunction in Liver Transplantation. Transplant Proc 2018; 50:1136-1141. [PMID: 29731081 DOI: 10.1016/j.transproceed.2018.02.034] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/20/2017] [Revised: 02/01/2018] [Accepted: 02/08/2018] [Indexed: 01/13/2023]
Abstract
BACKGROUND Antiphospholipid antibodies (aPL), including anticardiolipin (aCL), anti-β2-glycoprotein I (anti-β2GPI), and lupus anticoagulant (LA) antibodies, are frequently found in liver cirrhosis and associated with splanchnic vein thrombosis. Although the risk factors of early allograft dysfunction (EAD) are known, the association between EAD and aPL has been poorly investigated. We hypothesized that LA, potent aPL with thrombotic potential, may be associated with EAD development after living donor liver transplantation (LDLT). METHODS Data of 719 patients who underwent LDLT from February 2014 to June 2016 at our center were retrospectively collected and analyzed. Patients were divided into 2 groups according to the positivity of LA screening test (LA group [n = 148] vs no-LA group [n = 571]). Risk factors for EAD were investigated using multivariable regression analysis and inverse probability of treatment weighting (IPTW) of propensity scores. RESULTS The prevalence of LA screening positivity, confirmatory test positivity, and EAD was 20.6%, 1.1%, and 11.3%, respectively. aCL positivity rate was 7.5% and anti-β2GPI positivity rate was 7.0%. The EAD prevalence in LA and no-LA group was 25.7% and 7.5%, respectively. However, multivariable and IPTW analyses showed no association between EAD and LA screening positivity (P = .263 and P = .825, respectively), although a significant association was found in univariate analysis (odds ratio, 4.242; P < .001). Model for End-stage Liver Disease score, operation time, and C-reactive protein level remained significant after multivariable analysis. CONCLUSION A positive LA screening test result was associated with EAD only in the univariate analysis. Inflammation, based on C-reactive protein level, was more important for EAD development.

Abstract
INTRODUCTION Numerous extended donor criteria (EDC) have been identified in liver transplantation (LT), but different EDC have different impacts on graft and patient survival. This study aimed to identify major EDC (maEDC) that were best able to predict the outcome after LT and to examine the plausibility of an allocation algorithm based on these criteria. METHODS All consecutive LTs between 12/2006 and 03/2014 were included (n = 611). We analyzed the following EDC: donor age > 65 years, body mass index > 30, malignancy and drug abuse history, intensive care unit stay/ventilation > 7 days, aminotransferases > 3 times normal, serum bilirubin > 3 mg/dL, serum Na+ > 165 mmol/L, positive hepatitis serology, biopsy-proven macrovesicular steatosis (BPS) > 40%, and cold ischemia time (CIT) > 14 h. We analyzed hazard risk ratios of graft failure for each EDC and evaluated primary non-function (PNF). In addition, we analyzed 30-day, 90-day, 1-year, and 3-year graft survival. We established low- and high-risk graft (maEDC 0 vs. ≥ 1) and recipient (labMELD < 20 vs. ≥ 20) groups and compared the post-LT outcomes between these groups. RESULTS BPS > 40%, donor age > 65 years, and CIT > 14 h (all p < 0.05) were independent predictors of graft failure and patient mortality and increased PNF, 30-day, 90-day, 1-year, and 3-year graft failure rates. Three-year graft and patient survival decreased in recipients of ≥ 1 maEDC grafts (all p < 0.05) and LT of high-risk grafts into high-risk recipients yielded worse outcomes compared with other groups. CONCLUSION Donor age > 65 years, BPS > 40%, and CIT > 14 h are major EDC that decrease short and 3-year graft survival, and 3-year patient survival. An allocation algorithm based on maEDC and labMELD is therefore plausible.

Abstract
Early allograft dysfunction (EAD) is considered a precursor to graft loss in liver transplantation. To date, the use of preoperative serum cytokine profiles to predict EAD development has not been systematically investigated in living donor liver transplantation (LDLT). Here, we investigated the association between preoperative serum cytokine profiles and EAD development in LDLT patients.Serum cytokine profiles collected preoperatively and on postoperative day 7 were retrospectively reviewed. The specific serum cytokines analyzed included interleukin (IL)-2, IL-6, IL-10, IL-12, IL-17, interferon (IFN)-γ, and tumor necrosis factor (TNF)-α. The cytokine levels of patients with EAD were compared with those of patients without EAD and the impact of cytokine levels on the occurrence of EAD was evaluated.Preoperatively, the serum levels of IL-6, 10, 17, and TNF-α were significantly higher in the EAD group than in the non-EAD group. In univariate logistic analysis, the preoperative levels of IL-6, IL-10, IL-17, IFN-γ, and TNF-α were potentially associated with EAD development. After multivariate logistic analysis, higher preoperative serum levels of IL-6 and 17 were significantly associated with EAD development. In addition, the incidence of EAD increased as the preoperative serum levels of IL-6 and IL-17 increased.Preoperative serum levels of IL-6 and IL-17 were significantly associated with EAD development in LDLT.

Abstract
BACKGROUND Pig-to-nonhuman primate orthotopic liver xenotransplantation is often accompanied by thrombocytopenia and coagulation disorders. Furthermore, the release of cytokines can trigger cascade reactions of coagulation and immune attacks within transplant recipients. To better elucidate the process of inflammation in liver xenograft recipients, we utilized a modified heterotopic auxiliary liver xenotransplantation model for xeno-immunological research. We studied the cytokine profiles and the relationship between cytokine levels and xenograft function after liver xenotransplantation. METHODS Appropriate donor and recipient matches were screened using complement-dependent cytotoxicity assays. Donor liver grafts from α1,3-galactosyltransferase gene-knockout (GTKO) pigs or GTKO pigs additionally transgenic for human CD47 (GTKO/CD47) were transplanted into Tibetan macaques via two different heterotrophic auxiliary liver xenotransplantation procedures. The cytokine profiles, hepatic function, and coagulation parameters were monitored during the clinical course of xenotransplantation. RESULTS Xenograft blood flow was stable in recipients after heterotopic auxiliary transplantation. A Doppler examination indicated that the blood flow speed was faster in the hepatic artery (HA) and hepatic vein (HV) of xenografts subjected to the modified Sur II (HA-abdominal aorta+HV-inferior vena cava) procedure than in those subjected to our previously reported Sur I (HA-splenic artery+HV-left renal vein) procedure. Tibetan macaques receiving liver xenografts did not exhibit severe coagulation disorders or immune rejection. Although the recipients did suffer from a rapid loss of platelets, this loss was mild. In blood samples dynamically collected after xenotransplantation (post-Tx), dramatic increases in the levels of monocyte chemoattractant protein 1, interleukin (IL)-8, granulocyte-macrophage colony-stimulating factor, IL-6, and interferon gamma-induced protein 10 were observed at 1 hour post-Tx, even under immunosuppression. We further confirmed that the elevation in individual cytokine levels was correlated with the onset of graft damage. Finally, the release of cytokines might contribute to leukocyte infiltration in the xenografts. CONCLUSION Here, we established a modified auxiliary liver xenotransplantation model resulting in near-normal hepatic function. Inflammatory cytokines might contribute to early damage in liver xenografts. Controlling the systemic inflammatory response of recipients might prevent early post-Tx graft dysfunction.

Abstract
Although early allograft dysfunction (EAD) negatively impacts survival from the first months following liver transplantation (LT), direct-acting antiviral agents (DAAs) have revolutionized hepatitis C virus (HCV) therapy. We investigated the EAD definition best predicting 90-day graft loss and identified EAD risk factors in HCV-positive recipients. From November 2002 to June 2016, 603 HCV-positive patients (hepatocellular carcinoma, 53.4%) underwent a first LT with HCV-negative donors. The median recipient Model for End-Stage Liver Disease (MELD) score was 15, and the median donor age was 63 years. At LT, 77 (12.8%) patients were HCV RNA negative; negativization was achieved and maintained by pre-LT antiviral therapy (61 patients) or pre-LT plus a pre-emptive post-LT course (16 patients); 60 (77.9%) patients received DAAs and 17 (22.1%) interferon. We compared 3 different EAD definitions: (1) bilirubin ≥ 10 mg/dL or international normalized ratio ≥ 1.6 on day 7 after LT or aspartate aminotransferase or alanine aminotransferase > 2000 IU/L within 7 days of LT; (2) bilirubin > 10 mg/dL on days 2-7 after LT; and (3) MELD ≥ 19 on day 5 after LT. EAD defined by MELD ≥ 19 on day 5 after LT had the lowest negative (0.1) and the highest positive (1.9) likelihood ratio to predict 90-day graft loss. At 90 days after LT, 9.2% of recipients with EAD lost their graft as opposed to 0.7% of those without EAD (P < 0.001). At multivariate analysis, considering variables available at LT, MELD at LT of >25 (OR = 7.4) or 15-25 (OR = 3.2), graft macrovesicular steatosis ≥ 30% (OR = 6.7), HCV RNA positive at LT (OR = 2.7), donor age > 70 years (OR = 2.0), earlier LT era (OR = 1.8), and cold ischemia time ≥ 8 hours (OR = 1.8) were significant risk factors for EAD. In conclusion, in HCV-positive patients, MELD ≥ 19 on day 5 after LT best predicts 90-day graft loss. Preventing graft infection by pre-/peri-LT antiviral therapy reduces EAD incidence and could be most beneficial in high-MELD patients and recipients of suboptimal grafts.
