Abstract
Abstract
Background and aim
Transplantation (Tx) of non-vascularized rectus fascia (NVRF) is a valid option in solid organ transplant recipients to avoid open abdomen after Tx. To extrapolate this technique for non-Tx patients, we investigated in a preclinical rabbit model the feasibility of transplanting NVRF in a syngeneic (Syn) versus allogeneic (Allo) strain without using immunosuppression (IS). Short-term outcome was evaluated after 4 weeks.
Material and methods
A validated rabbit model of NVRF Tx was used comparing 6 Syn New Zealand White (NZW) rabbits versus 6 Allo Mixed breed to NZW Tx without IS. Animals were macroscopically analyzed at harvesting after 4 weeks for graft integration, herniation, adhesions, seroma, hematoma, and surgical site infections. Histological and immunohistochemical analysis was performed to assess inflammatory cell reaction and neovascularization. Mechanical testing was performed to assess the thickness, stiffness and strength.
Results
Results showed similar sufficient macroscopic ingrowth of the NVRF in both groups. At the histological level, cell infiltration suggested a clearing reaction more than a rejection-based inflammation, which was more pronounced in the Allo group. No significant differences were seen concerning mechanical properties.
Conclusions
In a validated rabbit model of NVRF Tx, we showed that Tx was possible in an Allo strain without the need for IS, resulting in satisfying short term inflammatory and mechanical outcomes. Longer-term experiments are needed to evaluate the effect of graft integration and possible hernia development.

Abstract
Abstract
Objective
In the era of organ shortage, redo liver transplantation (reLT) is frequently discussed in terms of expected poor outcome, high cost and therefore wasteful resources. However, there is a lack of benchmark data to reliably assess outcomes after reLT. The aim of this study was to define the ideal reLT case, and to establish clinically relevant benchmark values for best achievable outcome in reLT.
Methods
We collected data on reLT between January 2010 and December 2018 from 22 high volume transplant centers on three continents. Benchmark cases were defined as recipients with model of end-stage liver disease score <=25, absence of portal vein thrombosis, no mechanical ventilation before surgery, receiving a graft from a donor after brain death. In addition, early reLT including those for primary non-function (PNF) were excluded. Clinically relevant endpoints covering intra- and postoperative course were selected and complications were graded by severity using the Clavien-Dindo classification and the comprehensive complication index (CCI). The benchmark cutoff for each outcome was derived from the 75th percentile of the median values of all benchmark centers, indicating the “best achievable” result. To assess the utility of the newly established benchmark values, we analyzed patients who received reLT for PNF (non-benchmark patients).
Results
Out of 1110 reLT 413 (37.2%) qualified as benchmark cases. Benchmark values included: Length of intensive care unit and hospital stay: <=6 and <=24 days, respectively; Clavien-Dindo grade >=3a complications and the CCI at 1 year: <=76% and <=72.2, respectively; in-hospital and 1-year mortality rates: <=14.0% and <=14.3%, respectively. The cutoffs for transplant-specific complications such as biliary complications at 1 year, outflow problems at 1 year and hepatic artery thrombosis at discharge were <=27.3%, <=2.5% and <=4.8%, respectively. Patients receiving a reLT for PNF showed mean outcome values all outside the reLT benchmark values. In-hospital mortality rate was 34.4% and the mean CCI at discharge 68.8.
Conclusion
ReLT remains associated with high morbidity and mortality. The availability of benchmark values for outcome parameters of reLT may serve for comparison in any future analyses of individuals, patient groups, or centers, but also in the evaluation of new therapeutic strategies and principles.

Abstract
BACKGROUND Transarterial chemoembolization (TACE) in patients with hepatocellular cancer (HCC) on the waiting list for liver transplantation may be associated with an increased risk for hepatic artery complications. The present study aims to assess the risk for, primarily, intraoperative technical hepatic artery problems and, secondarily, postoperative hepatic artery complications encountered in patients who received TACE before liver transplantation. METHODS Available data from HCC liver transplantation recipients across six European centres from January 2007 to December 2018 were analysed in a 1 : 1 propensity score-matched cohort (TACE versus no TACE). Incidences of intraoperative hepatic artery interventions and postoperative hepatic artery complications were compared. RESULTS Data on postoperative hepatic artery complications were available in all 876 patients (425 patients with TACE and 451 patients without TACE). Fifty-eight (6.6 per cent) patients experienced postoperative hepatic artery complications. In total 253 patients who had undergone TACE could be matched to controls. In the matched cohort TACE was not associated with a composite of hepatic artery complications (OR 1.73, 95 per cent c.i. 0.82 to 3.63, P = 0.149). Data on intraoperative hepatic artery interventions were available in 825 patients (422 patients with TACE and 403 without TACE). Intraoperative hepatic artery interventions were necessary in 69 (8.4 per cent) patients. In the matched cohort TACE was not associated with an increased incidence of intraoperative hepatic artery interventions (OR 0.94, 95 per cent c.i. 0.49 to 1.83, P = 0.870). CONCLUSION In otherwise matched patients with HCC intended for liver transplantation, TACE treatment before transplantation was not associated with higher risk of technical vascular issues or hepatic artery complications.

Abstract
Since January 2020, the Novel Coronavirus Disease 2019 (COVID-19) pandemic has dramatically impacted the world. In March 2020, the COVID-19 epidemic reached Belgium creating uncertainty towards all aspects of life. There has been an impressive capacity and solidarity of all healthcare professionals to acutely reconvert facilities to treat these patients. In the context of liver transplantation (LTx), concerns are raised about organ donation shortage and safety, the ethics of using limited healthcare resources for LTx, selection criteria for LTx during the epidemic and the risk of de novo COVID-19 infection on the waiting list and after LTx. BeLIAC makes several recommendations to try to mitigate the deleterious effect that this epidemic has/will have on donation and LTx, taking into account the available resources, and trying to maximize patients and healthcare professionals' safety.

Abstract
Abstract
Background
When the blood supply ceases in a deceased organ donor, ischaemic injury starts. Kidneys are cooled to reduce cellular metabolism and minimize ischaemic injury. This cooling is slow and kidneys are lukewarm during nephrectomy. Smaller single-centre studies have shown that prolonged donor nephrectomy time decreases early kidney transplant function, but the effect on long-term outcome has never been investigated in large multicentre cohort studies.
Methods
The relationship between donor nephrectomy time and death-censored graft survival was evaluated in recipients of single adult-to-adult, first-time deceased-donor kidneys transplanted in the Eurotransplant region between 2004 and 2013.
Results
A total of 13 914 recipients were included. Median donor nephrectomy time was 51 (i.q.r. 39–65) min. Kidneys donated after circulatory death had longer nephrectomy times than those from brain-dead donors: median 57 (43–78) versus 50 (39–64) min respectively (P < 0·001). Donor nephrectomy time was independently associated with graft loss when kidneys were donated after circulatory death: adjusted hazard ratio (HR) 1·05 (95 per cent c.i. 1·01 to 1·09) per 10-min increase (P = 0·026). The magnitude of this effect was comparable to the effect of each hour of additional cold ischaemia: HR 1·04 (1·01 to 1·07) per h (P = 0·004). For kidneys donated after brain death, there was no effect of nephrectomy time on graft survival: adjusted HR 1·01 (0·98 to 1·04) per 10 min (P = 0·464).
Conclusion
Prolonged donor nephrectomy time impairs graft outcome in kidneys donated after circulatory death. Keeping this short, together with efficient cooling during nephrectomy, might improve outcome.

Abstract
Acute graft-versus-host disease (GVHD) after liver transplant (LTx) is a rare complication with a high mortality rate. Recently, monoclonal antibody (mAb) treatment, specifically with anti-interleukin 2 receptor antibodies (IL2RAb) and anti-tumor necrosis factor-α antibodies (TNFAb), has gained increasing interest. However, evidence is mostly limited to case reports and the efficacy remains unclear. Here, we describe 5 patients with LTx-associated GVHD from our center and provide the results of our systematic literature review to evaluate the potential therapeutic benefit of IL2RAb/TNFAb treatment. Of the combined population of 155 patients (5 in our center and 150 through systematic search), 24 were given mAb (15.5%)-4 with TNFAb (2.6%) and 17 with IL2RAb (11%) ("mAb group")-and compared with patients who received other treatments (referred to as "no-mAb group"). Two-sided Fisher exact tests revealed a better survival when comparing treatment with mAb versus no-mAb (11/24 vs 27/131; P = .018), TNFAb versus no-mAb (3/4 vs 27/131; P = .034), and IL2RAb versus no-mAb (8/17 vs 27/131; P = .029). This systematic review suggests a beneficial effect of mAb treatment and a promising role for TNFAb and IL2RAb as a first-line strategy to treat LTx-associated acute GVHD.

Abstract
Circulatory death donor (DCD) kidney transplantations are steadily increasing. Consensus reports recommend limiting donor warm ischemia time (DWIT) in DCD donation, although an independent effect on graft outcome has not been demonstrated. We investigated death-censored graft survival in 18 065 recipients of deceased-donor kidney transplants in the Eurotransplant region: 1059 DCD and 17 006 brain-dead donor (DBD) kidney recipients. DWIT was defined as time from circulatory arrest until cold flush. DCD donation was an independent risk factor for graft failure (adjusted hazard ratio [HR] 1.28, 95% CI 1.10-1.46), due to an increased risk of primary nonfunction (62/1059 vs 560/17 006; P < .0001). With DWIT in the model, DCD donation was no longer a risk factor, demonstrating that DWIT explains the inferior graft survival of DCD kidneys. Indeed, DCD transplants with short DWIT have graft survival comparable to that of standard-criteria DBD transplants (P = .59). DWIT also associated with graft failure in DCDs (adjusted HR 1.20 per 10-minute increase, 95% CI 1.03-1.42). At 5 years after transplantation, graft failure occurred in 14 of 133 recipients (10.5%) with DWIT <10 minutes, 139 of 555 recipients (25.0%) with DWIT between 10 and 19 minutes, and 117 of 371 recipients (31.5%) with DWIT ≥20 minutes. These findings support the expert opinion-based guidelines to limit DWIT.

Abstract
BACKGROUND Ischaemia-reperfusion injury is inevitable during renal transplantation and can lead to delayed graft function and primary non-function. Preconditioning, reconditioning and postconditioning with argon and xenon protects against renal ischaemia-reperfusion injury in rodent models. The hypothesis that postconditioning with argon or xenon inhalation would improve graft function in a porcine renal autotransplant model was tested. METHODS Pigs (n = 6 per group) underwent left nephrectomy after 60 min of warm ischaemia (renal artery and vein clamping). The procured kidney was autotransplanted in a separate procedure after 18 h of cold storage, immediately after a right nephrectomy. Upon reperfusion, pigs were randomized to inhalation of control gas (70 per cent nitrogen and 30 per cent oxygen), argon (70 per cent and 30 per cent oxygen) or xenon (70 per cent and 30 per cent oxygen) for 2 h. The primary outcome parameter was peak plasma creatinine; secondary outcome parameters included further markers of graft function (creatinine course, urine output), graft injury (aspartate aminotransferase, heart-type fatty acid-binding protein, histology), apoptosis and autophagy (western blot, terminal deoxynucleotidyl transferase dUTP nick-end labelling (TUNEL) staining), inflammatory mediators and markers of cell survival/growth (mRNA and tissue protein quantification), and animal survival. Results are presented as median (i.q.r.). ANOVA and Kruskal-Wallis tests were used where indicated. RESULTS Peak plasma creatinine levels were similar between the groups: control 20·8 (16·4-23·1) mg/dl, argon 21·4 (17·1-24·9) mg/dl and xenon 19·4 (17·5-21·0) mg/dl (P = 0·607). Xenon was associated with an increase in autophagy and proapoptotic markers. Creatinine course, urine output, injury markers, histology, survival and inflammatory mediators were not affected by the intervention. CONCLUSION Postconditioning with argon or xenon did not improve kidney graft function in this experimental model. Surgical relevance Ischaemia-reperfusion injury is inevitable during renal transplantation and can lead to delayed graft function and primary non-function. Based on mainly small animal experiments, noble gases (argon and xenon) have been proposed to minimize this ischaemia-reperfusion injury and improve outcomes after transplantation. The hypothesis that postconditioning with argon or xenon inhalation would improve graft function was tested in a porcine kidney autotransplantation model. The peak plasma creatinine concentration was similar in the control, argon and xenon groups. No other secondary outcome parameters, including animal survival, were affected by the intervention. Xenon was associated with an increase in autophagy and proapoptotic markers. Despite promising results in small animal models, postconditioning with argon or xenon in a translational model of kidney autotransplantation was not beneficial. Clinical trials would require better results.

Abstract
Recent studies raised the concern that warm ischemia during completion of vascular anastomoses in kidney implantation harms the transplant, but its precise impact on outcome and its interaction with other risk factors remain to be established. We investigated the relationship between anastomosis time and graft survival at 5 years after transplantation in 13 964 recipients of deceased donor solitary kidney transplants in the Eurotransplant region. Anastomosis time was independently associated with graft loss after adjusting for other risk factors (adjusted hazard ratio [HR] 1.10 for every 10-min increase, 95% confidence interval [CI] 1.06-1.14; p < 0.0001), whereas it did not influence recipient survival (HR 1.00, 95% CI 0.97-1.02). Kidneys from donation after circulatory death (DCD) were less tolerant of prolonged anastomosis time than kidneys from donation after brain death (p = 0.02 for interaction). The additive effect of anastomosis time with donor warm ischemia time (WIT) explains this observation because DCD status was no longer associated with graft survival when adjusted for this summed WIT, and there was no interaction between DCD status and summed WIT. Time to create the vascular anastomoses in kidney transplantation is associated with inferior transplant outcome, especially in recipients of DCD kidneys.

Abstract
Intestinal transplantation (ITx) remains challenged by frequent/severe rejections and immunosuppression-related complications (infections/malignancies/drug toxicity). We developed the Leuven Immunomodulatory Protocol (LIP) in the lab and translated it to the clinics. LIP consists of experimentally proven maneuvers, destined to promote T-regulatory (Tregs)-dependent graft-protective mechanisms: donor-specific blood transfusion (DSBT); avoiding high-dose steroids/calcineurin-inhibitors; and minimizing reperfusion injury and endotoxin translocation. LIP was tested in 13 consecutive ITx from deceased donors (2000-2014) (observational cohort study). Recipient age was 37 years (2.8-57 years). Five-year graft/patient survival was 92%. One patient died at 9 months due to aspergillosis, another at 12 years due to nonsteroidal anti-inflammatory drug-induced enteropathy. Early acute rejection (AR) developed in two (15%); late AR in three (23%); all were reversible. No chronic rejection (CR) occurred. No malignancies developed and estimated glomerular filtration rate remained stable post-Tx. At last follow-up (3.5 years [0.5-12.5 years]), no donor-specific antibodies were detected and 11 survivors were total parenteral nutrition free with a Karnofsky score >90% in 8 recipients (follow-up >1 years). A high frequency of circulating CD4+ CD45RA- Foxp3hi memory Tregs was found (1.8% [1.39-2.21]), comparable to tolerant kidney transplant (KTx) recipients and superior to stable immunosuppression (IS)-KTx, KTx with CR, and healthy volunteers. In this ITx cohort we show that DSBT in a low-inflammatory/pro-regulatory environment activates Tregs at levels similar to tolerant-KTx, without causing sensitization. LIP limits rejection under reduced IS and thereby prolongs long-term survival to an extent not previously attained after ITx.

Abstract
UNLABELLED Bone loss and vascular calcification coincide in patients with end-stage renal disease, similar as to what is observed in the general population. In the present bone biopsy study, we provide further evidence that (micro-)inflammation may represent a common soil for both diseases. INTRODUCTION Vascular calcification is a common complication of end-stage renal disease (ESRD) and is predictive of subsequent cardiovascular disease and mortality. Mounting evidence linking bone disorders with vascular calcification has contributed to the development of the concept of the bone-vascular axis. Inflammation is involved in the pathogenesis of both disorders. The aim of the present study was to evaluate the relationship between aortic calcification, inflammation, and bone histomorphometry in patients with ESRD. METHODS Parameters of inflammation and mineral metabolism were assessed in 81 ESRD patients (55 ± 13 year, 68 % male) referred for renal transplantation. Static bone histomorphometry parameters were determined on transiliac bone biopsies performed during the transplant procedure. Aortic calcification was quantified on lateral lumbar X-rays using the Kauppila method. RESULTS Aortic calcification, low bone turnover, and low bone area were observed in 53, 37, and 21 % of patients respectively. Inflammatory markers were found to be independently associated with aortic calcification (hsIL-6) and low bone area (TNF-α). Low bone area associated with aortic calcification, independent of age, diabetes, and inflammation. CONCLUSIONS Low bone area and inflammation associates with aortic calcification, independent of each other and traditional risk factors. Our data emphasize the role of (micro-)inflammation in the bone-vascular axis in CKD.

Abstract
Epithelioid hemangioendothelioma (EHE) is a rare vascular tumor with variable biological and clinical behavior. There is increasing experience with liver transplantation (LiTx) for hepatic EHE, even in cases of extrahepatic disease localization. Until now, no cases of lung transplantation (LuTx) had been reported for pulmonary EHE. This report describes three cases of EHE with multifocal disease in patients who underwent either serial or combined LiTx and LuTx.

Abstract
Multivisceral transplantation (MvTx) for diffuse venous portomesenteric thrombosis is a surgically and anesthesiologically challenging procedure, partly because of the risk of massive bleeding during visceral exenteration. Preoperative visceral artery embolization might reduce this risk. In three consecutive MvTx, the celiac trunk (CT) and superior mesenteric artery (SMA) were embolized immediately pretransplant. We analyzed demographics, serum D-lactate, pH, base excess, hemoglobin, blood pressure, transfused packed cell (PC) units, intervention time and outcome. Results are reported as median (range). All recipients were male (43, 22, 47 years old). Portomesenteric thrombosis followed antiphospholipid syndrome, neuroendocrine tumor and liver cirrhosis. A peritransplant D-lactate peak of 6.1 (5.1-7.6) mmol/L, lowest pH of 7.24 (7.18-7.36) and lowest base excess level of -9.5 (-7.6 to -11.5) were observed. Values normalized within 3 h posttransplant. Embolization and exenteration times were 80 (70-90) min and 140 (130-165) min, respectively, during which blood pressure remained stable, lowest hemoglobin was 6.1 (6.1-7.6) g/dL and three (2-4) PC were administered. All procedures were uneventful. Follow-up was 7 (4-9) months. The first patient died 4 months post-MvTx after an intracranial bleeding; the other patients are doing well. Our experience suggests that preoperative embolization of CT and SMA facilitates native organ resection in MvTx.

Abstract
Whether warm ischemia during the time to complete the vascular anastomoses determines renal allograft function has not been investigated systematically. We investigated the effect of anastomosis time on allograft outcome in 669 first, single kidney transplantations from brain-dead donors. Anastomosis time independently increased the risk of delayed graft function (odds ratio per minute [OR] 1.05, 95% confidence interval [CI] 1.02-1.07, p < 0.001) and independently impaired allograft function after transplantation (p = 0.009, mixed-models repeated-measures analysis). In a subgroup of transplant recipients, protocol-specified biopsies at 3 months (n = 186), 1 year (n = 189), and 2 years (n = 153) were blindly reviewed. Prolonged anastomosis time independently increased the risk of interstitial fibrosis and tubular atrophy on these protocol-specified biopsies posttransplant (p < 0.001, generalized linear models). In conclusion, prolonged anastomosis time is not only detrimental for renal allograft outcome immediately after transplantation, also longer-term allograft function and histology are affected by the duration of this warm ischemia.

Abstract
UNLABELLED DIAMOND: multicenter, 24-week, randomized trial investigating the effect of different once-daily, prolonged-release tacrolimus dosing regimens on renal function after de novo liver transplantation. Arm 1: prolonged-release tacrolimus (initial dose 0.2mg/kg/day); Arm 2: prolonged-release tacrolimus (0.15-0.175mg/kg/day) plus basiliximab; Arm 3: prolonged-release tacrolimus (0.2mg/kg/day delayed until Day 5) plus basiliximab. All patients received MMF plus a bolus of corticosteroid (no maintenance steroids). PRIMARY ENDPOINT eGFR (MDRD4) at Week 24. Secondary endpoints: composite efficacy failure, BCAR and AEs. Baseline characteristics were comparable. Tacrolimus trough levels were readily achieved posttransplant; initially lower in Arm 2 versus 1 with delayed initiation in Arm 3. eGFR (MDRD4) was higher in Arms 2 and 3 versus 1 (p = 0.001, p = 0.047). Kaplan-Meier estimates of composite efficacy failure-free survival were 72.0%, 77.6%, 73.9% in Arms 1-3. BCAR incidence was significantly lower in Arm 2 versus 1 and 3 (p = 0.016, p = 0.039). AEs were comparable. Prolonged-release tacrolimus (0.15-0.175mg/kg/day) immediately posttransplant plus basiliximab and MMF (without maintenance corticosteroids) was associated with lower tacrolimus exposure, and significantly reduced renal function impairment and BCAR incidence versus prolonged-release tacrolimus (0.2mg/kg/day) administered immediately posttransplant. Delayed higher-dose prolonged-release tacrolimus initiation significantly reduced renal function impairment compared with immediate posttransplant administration, but BCAR incidence was comparable.

Abstract
BACKGROUND AND STUDY AIMS The Budd-Chiari syndrome is a rare disorder characterized by hepatic venous outflow obstruction. A step-wise management was recently proposed. The aim of this study is to reassess our treatment approach and long-term outcome. PATIENTS AND METHODS The data of 37 Budd-Chiari patients, seen in our unit, were critically analyzed and compared with the ENVIE (European Network For Vascular Disorders of the Liver) data. RESULTS Most patients had multiple prothrombotic conditions (41%), of which an underlying myeloproliferative neoplasm was the most frequent (59%). The JAK2V617F mutation was associated with more complete occlusion of all hepatic veins (JAK2 mutation +: 70% vs JAK2 mutation -: 23% and a higher severity score. The step-wise treatment algorithm used in our unit, in function of the severity of the liver impairment and the number and the extension of hepatic veins occluded, resulted in the following treatments: only anticoagulation (n = 7.21%), recanalization procedure (n = 4.21%), portosystemic shunts (n = 9.26%) and liver transplantation (n = 14.44%). This resulted in a 10 year survival rate of 90%. Treatment of the underlying hemostatic disorder offered a low recurrence rate. None of the 21 patients with a myeloproliferative neoplasm died in relation to the hematologic disorder. CONCLUSIONS An individualized treatment regimen consisting of anticoagulation and interventional radiology and/or transplantation when necessary and strict follow-up of the underlying hematologic disorder, provided an excellent long-term survival, which confirm the data of the ENVIE study.

Abstract
Efficacy and safety of protein kinase C inhibitor sotrastaurin (STN) with tacrolimus (TAC) was assessed in a 24-month, multicenter, phase II study in de novo liver transplant recipients. A total of 204 patients were randomized (1:1:1:1) to STN 200 mg b.i.d. + standard-exposure TAC (n = 50) or reduced-exposure TAC (n = 52), STN 300 mg b.i.d. + reduced-exposure TAC (n = 50), or mycophenolate mofetil (MMF) 1 g b.i.d. + standard-exposure TAC (control, n = 52); all with steroids. Owing to premature study termination, treatment comparisons were only conducted for Month 6. At Month 6, composite efficacy failure rates (treated biopsy-proven acute rejection episodes of Banff grade ≥1, graft loss, or death) were 25.0%, 16.5%, 20.9% and 15.9% for STN 200 mg + standard TAC, STN 200 mg + reduced TAC, STN 300 mg + reduced TAC and control groups, respectively. Median estimated glomerular filtration rates were 84.0, 83.3, 81.1 and 75.3 mL/min/1.73 m(2), respectively. Gastrointestinal events (constipation, diarrhea, and nausea), infection, and tachycardia were more frequent in STN groups. More patients in STN groups experienced serious adverse events compared with the control group (62.3-70.8% vs. 51.9%). STN-based regimens were associated with a higher efficacy failure rate and higher incidence of adverse events with no significant difference in renal function between the groups.

Abstract
Between 2003 and 2012, 42 869 first liver transplantations performed in Europe with the use of either University of Wisconsin solution (UW; N = 24 562), histidine-tryptophan-ketoglutarate(HTK; N = 8696), Celsior solution (CE; N = 7756) or Institute Georges Lopez preservation solution (IGL-1; N = 1855) preserved grafts. Alternative solutions to the UW were increasingly used during the last decade. Overall, 3-year graft survival was higher with UW, IGL-1 and CE (75%, 75% and 73%, respectively), compared to the HTK (69%) (p < 0.0001). The same trend was observed with a total ischemia time (TIT) >12 h or grafts used for patients with cancer (p < 0.0001). For partial grafts, 3-year graft survival was 89% for IGL-1, 67% for UW, 68% for CE and 64% for HTK (p = 0.009). Multivariate analysis identified HTK as an independent factor of graft loss, with recipient HIV (+), donor age ≥65 years, recipient HCV (+), main disease acute hepatic failure, use of a partial liver graft, recipient age ≥60 years, no identical ABO compatibility, recipient hepatitis B surface antigen (-), TIT ≥ 12 h, male recipient and main disease other than cirrhosis. HTK appears to be an independent risk factor of graft loss. Both UW and IGL-1, and CE to a lesser extent, provides similar results for full size grafts. For partial deceased donor liver grafts, IGL-1 tends to offer the best graft outcome.

Abstract
Isolated lung transplantation (LuTx) and liver transplantation are established treatments for irreversible lung and liver failure. Combined liver and lung transplantation (cLiLuTx) is a less common, but approved therapy of combined organ failure, mostly applied in patients suffering from progressive cystic fibrosis and advanced liver disease. We report a patient who was listed for LuTx due to end-stage chronic obstructive pulmonary disease and who developed drug-induced acute hepatic failure. The only therapeutic option was hyper-urgent cLiLuTx. To correct the poor coagulation in order to reduce the per-operative risk of bleeding, the liver was transplanted first. In anticipation of the longer lung preservation time, cold flushed lungs were preserved on a portable lung perfusion device for ex vivo normothermic perfusion for 11 h 15 min, transplanted sequentially off-pump, and reperfused after a total ex vivo time of 13 h 32 min and 16 h for the first and second lung, respectively. Ten months later, the patient is doing well and no rejection occurred. Normothermic ex vivo lung perfusion may help to prolong preservation time, facilitating long-distance transport and combined organ transplantation.

We describe the case of a 26-year-old man with acute liver failure secondary to ingestion of khat (Catha edulis) leaves. In fact, this is the first case of acute liver failure due to khat reported outside the United Kingdom. The combination of specific epidemiologic data (young man of East African origin) and clinical features (central nervous system stimulation, withdrawal reactions, toxic autoimmune-like hepatitis) led to the diagnosis. Mechanisms of action and potential side effects of khat are elaborated on.

Abstract
The enduring kidney graft shortage has led to the increasing use of expanded-criteria donors as well as kidneys donated after cardiac death, triggering the revival of machine perfusion preservation. Indeed, machine perfusion not only preserves these kidneys better than static cold storage, but also has the potential to evaluate them. The presence of certain biomarkers, among them aspartate aminotransferase (AST) and heart-type fatty acid binding protein (H-FABP), has been demonstrated in the perfusate of human kidneys, making them potentially useful as biomarkers of graft quality. Neutrophil gelatinase-associated lipocalin (NGAL) which is believed to be released upon renal tubular cell injury is another biomarker candidate. However, because it is also released from neutrophils, it is currently unclear whether NGAL is a direct or indirect, inflammatory-mediated marker of kidney injury. To resolve this issue we established a pilot experiment to study the concentrations of AST, H-FABP, and NGAL in the perfusates of 6 porcine kidneys that were exposed to incremental periods of warm ischemia before machine perfusion for 22 hours. An ex vivo porcine model was chosen because preclinical large animal work remains necessary to refine machine perfusion technology and because the presence of these markers in perfusates of porcine kidneys had not been shown previously. All 3 biomarkers were detectable in the cold acellular perfusate; their release seemed to be proportionate to the degree of warm injury, albeit that this must be confirmed in a larger sample. In conclusion, NGAL is directly released by ischemically damaged kidneys, independent of neutrophil activation. In addition to NGAL, the determination of AST and H-FABP in perfusates of machine-perfused porcine kidneys is also feasible. Determination of these markers may be added to the arsenal of research tools for preclinical preservation research.

Abstract
Reduced glutathione (GSH), an important radical scavenger, has been added to various organ preservation solutions. Because GSH oxidizes into oxidized glutathione (GSSG) and only GSH has scavenging capacity, only GSH in the solution at the time of clinical use is relevant. The concentrations of GSH (GSH(conc)) and GSSG(conc) were determined in 2 static preservation solutions--University of Wisconsin (UW) and Celsior--and in 1 machine preservation solution--Kidney Preservation Solution 1 (KPS-1). We determined the half-life (T(1/2)) of freshly added GSH. The GSH(conc) in UW and KPS-1 was 0.006 ± 0.0018 mmol/L and 0.13 ± 0.30 mmol/L, respectively. The GSH(conc) in Celsior was 2.7 ± 0.17 mmol/L. The manufacturers of these solutions reported 3 mmol/L GSH. GSSG(conc) in UW, KPS-1, and Celsior was 1.58 ± 0.61 mmol/L, 1.13 ± 0.16 mmol/L, and 0.24 ± 0.01 mmol/L, respectively. T(1/2) of GSH in UW, KPS-1, and Celsior was 18 days, 86 days, and 83 days, respectively. The actual GSH(conc) in UW and KPS-1 at the time of clinical use was substantially lower than reported by the manufacturer, owing to the relatively short T(1/2) of GSH. For Celsior, the GSH(conc) was maintained. Therefore, addition of fresh GSH to UW and KPS-1 before clinical use is recommended.

Abstract
Kidney transplantation is the treatment of choice for end-stage renal disease whereas indications for intestinal transplantation are currently restricted to patients with irreversible small bowel failure and severe complications of total parenteral nutrition (mostly shortage and infection of venous accesses, major electrolyte disturbances and liver failure). Enteric hyperoxaluria is secondary to certain intestinal diseases like intestinal resections, chronic inflammatory bowel disease and other malabsorption syndromes and can lead to end-stage renal disease requiring kidney transplantation. We report two patients suffering from renal failure due to enteric hyperoxaluria (secondary to extensive intestinal resection) in whom we elected to replace not only the kidney but also the intestine to prevent recurrence of hyperoxaluria in the transplanted kidney.

Abstract
BACKGROUND Wider utilization of liver grafts from donors ≥ 70 years old could substantially expand the organ pool, but their use remains limited by fear of poorer outcomes. We examined the results at our center of liver transplantation (OLT) using livers from donors ≥ 70 years old. METHODS From February 2003 to August 2010, we performed 450 OLT including 58 (13%) using donors ≥ 70 whose outcomes were compared with those using donors <70 years old. RESULTS Cerebrovascular causes of death predominated among donors ≥ 70 (85% vs 47% in donors <70; P < .001). In contrast, traumatic causes of death predominated among donors <70 (36% vs 14% in donors ≥ 70; P = .002). Unlike grafts from donors <70 years old, grafts from older individuals had no additional risk factors (steatosis, high sodium, or hemodynamic instability). Both groups were comparable for cold and warm ischemia times. No difference was noted in posttransplant peak transaminases, incidence of primary nonfunction, hepatic artery thrombosis, biliary strictures, or retransplantation rates between groups. The 1- and 5-year patient survivals were 88% and 82% in recipients of livers <70 versus 90% and 84% in those from ≥ 70 years old (P = .705). Recipients of older grafts, who were 6 years older than recipients of younger grafts (P < .001), tended to have a lower laboratory Model for End-Stage Liver Disease score (P = .074). CONCLUSIONS Short and mid-term survival following OLT using donors ≥ 70 yo can be excellent provided that there is adequate donor and recipient selection. Septuagenarians and octogenarians with cerebrovascular ischemic and bleeding accidents represent a large pool of potential donors whose wider use could substantially reduce mortality on the OLT waiting list.

Abstract
We present the case of a 30-year-old female suffering from a type five maturity onset diabetes of the young deficiency, resulting in type 1 diabetes and terminal renal insufficiency. She also had chronic and refractory pruritis due to primary sclerosing cholangitis-like fibrosis. She underwent combined en bloc liver and pancreas transplantation and kidney transplantation. The postoperative course was complicated by a gastric outlet obstruction due to compression of the native gastroduodenal junction by the donor aortic tube. This was treated by construction of a roux-en-Y gastrojejunostomy at posttransplant day 24. To our knowledge, compression of the gastroduodenal junction by a donor aortic tube after combined liver and pancreas (or multivisceral) transplantation has not been reported previously.

Abstract
Static cold storage (CS) is the most widely used organ preservation method for deceased donor kidney grafts but there is increasing evidence that hypothermic machine perfusion (MP) may result in better outcome after transplantation. We performed an economic evaluation of MP versus CS alongside a multicenter RCT investigating short- and long-term cost-effectiveness. Three hundred thirty-six consecutive kidney pairs were included, one of which was assigned to MP and one to CS. The economic evaluation combined the short-term results based on the empirical data from the study with a Markov model with a 10-year time horizon. Direct medical costs of hospital stay, dialysis treatment, and complications were included. Data regarding long-term survival, quality of life, and long-term costs were derived from literature. The short-term evaluation showed that MP reduced the risk of delayed graft function and graft failure at lower costs than CS. The Markov model revealed cost savings of $86,750 per life-year gained in favor of MP. The corresponding incremental cost-utility ratio was minus $496,223 per quality-adjusted life-year (QALY) gained. We conclude that life-years and QALYs can be gained while reducing costs at the same time, when kidneys are preserved by MP instead of CS.

Abstract
Vascular renal resistance (RR) during hypothermic machine perfusion (HMP) is frequently used in kidney graft quality assessment. However, the association between RR and outcome has never been prospectively validated. Prospectively collected RR values of 302 machine-perfused deceased donor kidneys of all types (standard and extended criteria donor kidneys and kidneys donated after cardiac death), transplanted without prior knowledge of these RR values, were studied. In this cohort, we determined the association between RR and delayed graft function (DGF) and 1-year graft survival. The RR (mmHg/mL/min) at the end of HMP was an independent risk factor for DGF (odds ratio 38.1 [1.56-934]; p = 0.026) [corrected] but the predictive value of RR was low, reflected by a c-statistic of the receiver operator characteristic curve of 0.58. The RR was also found to be an independent risk factor for 1-year graft failure (hazard ratio 12.33 [1.11-136.85]; p = 0.004). Determinants of transplant outcome are multifactorial in nature and this study identifies RR as an additional parameter to take into account when evaluating graft quality and estimating the likelihood of successful outcome. However, RR as a stand-alone quality assessment tool cannot be used to predict outcome with sufficient precision.

Abstract
The prevalence of obesity has grown dramatically over the last decades, with nonalcoholic steatohepatitis increasingly observed. Therapeutic options for morbid obesity include bariatric surgery. Fatal liver failure (LF) has been recorded after jejunoileal bypass (JIB) but is controversial after biliopancreatic diversion (BPD, Scopinaro operation). We performed a survey on the frequency of liver transplantation (LT) after bariatric surgery in Belgium. An enquiry was sent to all Belgian liver transplant centers to investigate the occurrence of subacute and chronic LF after bariatric surgery. After weight-reduction surgery, 10 patients in 3 Belgian transplant centers were listed for LT due to severe hepatocellular failure. Nine of them had undergone a Scopinaro operation and 1 a jejunoileal bypass. The median time to develop LF was 5 years. The patient with JIB developed chronic LF after 25 years. Seven patients were transplanted; two died awaiting a graft and one is still on the waiting list. After LT, 1 patient developed rapid reappearance of LF at 10 months, requiring retransplantation. Two recipients died after LT because of multiorgan failure shortly after transplantation. In another case, a de novo cancer was fatal at 6 years' follow-up. The remaining recipients were doing well. According to this survey, the BPD operation carries a potential risk of LF. However, because there were only 10 cases, we remain unaware of the actual incidence of Scopinaro operation-induced LF. We advise strict follow-up of liver function and timely dismantling of BPD.

Abstract
Ethylene oxide (EO) is widely used as a sterilization gas for heat-sensitive devices. In EO-sensitized patients, this type of sterilization can cause rare but major allergic reactions such as hives, rash, asthma, or anaphylactic shock. Hemodialysis patients in particular are at risk of developing hypersensitivity to EO. In these patients, surgical interventions should be planned far in advance allowing a thorough EO-free preparation of all equipment needed for the surgery as well as for the pre-, peri-, and postoperative care. In contrast to elective surgery, kidney transplantation with allografts from deceased donors cannot be planned; exact timing is unpredictable. Furthermore, transplantation may take place years after patients have been put on the waiting list. Listing of patients sensitive for EO is therefore a logistical and medical challenge for all health care professionals involved in the patient's care (eg, surgeons, nephrologists, anesthetists, nurses, pharmacists, and sterilization specialists). This case report describes a patient with chronic kidney disease stage V who developed EO allergy during hemodialysis while waiting for a kidney transplantation. Diagnosis was made based on clinical signs and confirmed biochemically (including a positive radioallergosorbent test). Because the only treatment is avoidance of contact with EO-sterilized materials, a strict EO-free protocol was developed to allow an uneventful transplantation thereafter. Subsequently, 4 newly diagnosed EO-sensitive patients on the active kidney transplantation waiting list were diagnosed, and 1 of these patients has been transplanted successfully. EO allergy in patients on the waiting list for kidney transplantation is a unique challenging situation which, to the best of our knowledge, has not been reported yet for kidney transplantation. This report further highlights the logistical preparation of a renal transplantation, including anesthesiologic, surgical, and postoperative care.

Abstract
Endotipsitis or primary infection of a TIPS-stent, is an uncommon but possible life- threatening condition by its potential evolution to sepsis and death. Diagnosis should be suspected in patients with a TIPS-stent presenting with stent-dysfunction associated with fever or relapsing episodes of bacteremia/sepsis without any other alternative focus. A certain diagnosis is made by post-factum histopathological and/or microbiological examination of the TIPS-stent which is only possible after liver transplantation or at autopsy, whereas it can be highly suspected in case of repetitive positive blood-cultures without any other focus in a patient with a TIPS-stent. The microorganisms responsible for endotipsitis are most frequently of Gram-negative enteric origin. The regimen and duration of the treatment should be individualized and depends on multiple factors like the antibiotic sensitivity of the organism and the patients condition. In case of a fungal infection, longer treatment is recommended.
