Background Female sex has been reported as an independent predictor of severe post-liver transplantation (LT) chronic kidney disease. We performed a by sex post-hoc analysis of the SURF study, that investigated the prevalence of renal impairment following LT, aimed at exploring possible differences between sexes in the prevalence and course of post-LT renal damage. Methods All patients enrolled in the SURF study were considered evaluable for this sex-based analysis, whose primary objective was to evaluate by sex the proportion of patients with estimated Glomerular Filtration Rate (eGFR) 2 at inclusion and follow-up visit. Results Seven hundred thirty-eight patients were included in our analysis, 76% males. The proportion of patients with eGFR 2 was significantly higher in females at initial study visit (33.3 vs 22.8%; p = 0.005), but also before, at time of transplantation (22.9 vs 14.7%; p = 0.0159), as analyzed retrospectively. At follow-up, such proportion increased more in males than in females (33.9 vs 26.0%, p = 0.04). Mean eGFR values decreased over the study in both sexes, with no significant differences. Statistically significant M/F differences in patient distribution by O’Riordan eGFR levels were observed at time of transplant and study initial visit (p = 0.0005 and 0.0299 respectively), but not at follow-up. Conclusions Though the limitation of being performed post-hoc, this analysis suggests potential sex differences in the prevalence of renal impairment before and after LT, encouraging further clinical research to explore such differences more in depth.

Infections are a major complication of solid organ transplants (SOTs). This study aimed to describe recipients’ characteristics, and the frequency and etiology of infections and transplant outcome in liver and lung SOTs, and to investigate exposures associated to infection and death in liver transplant recipients. The study population included recipients of SOTs performed in Italy during a 1-year period in ten Italian lung transplant units and eight liver transplant units. Data on comorbidities, infections, retransplantation, and death were prospectively collected using a web-based system, with a 6-month follow-up. The cumulative incidence of infection was 31.7% and 47.8% in liver and lung transplants, respectively, with most infections occurring within the first month after transplantation. Gram-negatives, which were primarily multidrug-resistant, were the most frequent cause of infection. Death rates were 0.42 per 1000 recipient-days in liver transplants and 1.41 per 1000 recipient-days in lung transplants. Infection after SOT in adult liver recipients is associated to an increased risk of death (OR = 13.25; p-value < 0.001). Given the frequency of infection caused by multidrug-resistant microorganisms in SOT recipients in Italy and the heavy impact of infections on the transplant outcome, the reinforcement of surveillance and control activities to prevent the transmission of multidrug-resistant microorganisms in SOT recipients represents a priority. The implementation of the study protocol in liver and lung transplant units and the sharing of results have increased the awareness about the threat due to antimicrobial resistance in the country.

Background and aims Hepatitis C virus (HCV) reinfection following liver transplant (LT) is associated with reduced graft and patients survival. Before transplant, Sofosbuvir/Ribavirin (SOF/R) treatment prevents recurrent HCV in 96% of those patients achieving viral suppression for at least 4 weeks before transplant. We evaluated whether a bridging SOF-regimen from pre to post-transplant is safe and effective to prevent HCV recurrence in those patients with less than 4 week HCV-RNA undetectability at the time of transplant. Material and Methods From July 2014 SOF/R was given in 233 waitlisted HCV cirrhotics with/without hepatocellular carcinoma (HCC) within an Italian Compassionate Program. One-hundred were transplanted and 31 patients (31%) treated by SOF/R bridging therapy were studied Results LT indication in bridge subgroup was HCC in 22 and decompensated cirrhosis in 9. HCV-genotype was 1/4 in 18 patients. SOF 400 mg/day and R (median dosage 800 mg/day) were given for a median of 35 days before LT. At transplant time, 19 patients were still HCV-RNA positive (median HCV-RNA 58 IU/ml). One recipient had a virological breakthrough at week 4 post-transplant; one died, on treatment, 1-month post-transplant for sepsis and 29/31 achieved a 12-week sustained virological response (94%). Acute cellular rejection occurred in 4 recipients. On September 2016, 30 recipients (97%) are alive with a median follow-up of 18 months (range 13-25). Conclusions In patients with suboptimal virological response at LT a bridging SOF/R regimen helps avoiding post-transplant graft reinfection. This article is protected by copyright.

Donor-recipient match is a matter of debate in liver transplantation. D-MELD (donor age × recipient biochemical model for end-stage liver disease [MELD]) and other factors were analyzed on a national Italian database recording 5946 liver transplants. Primary endpoint was to determine factors predictive of 3-year patient survival. D-MELD cutoff predictive of 5-year patient survival 1628). At 3 years, the odds ratio (OR) for death was 2.03 (95% confidence interval [CI], 1.44-2.85) in D-MELD class C versus B. The OR was 0.40 (95% CI, 0.24-0.66) in class A versus class B. Other predictors were hepatitis C virus (HCV; OR = 1.42; 95% CI, 1.11-1.81), hepatitis B virus (HBV; OR = 0.69; 95% CI, 0.51-0.93), retransplant (OR = 1.82; 95% CI, 1.16-2.87) and low-volume center (OR = 1.48; 95% CI, 1.11-1.99). Cox regressions up to 90 months confirmed results. The hazard ratio was 1.97 (95% CI, 1.59-2.43) for D-MELD class C versus class B and 0.42 (95% CI, 0.29-0.60) for D-MELD class A versus class B. Recipient age, HCV, HBV and retransplant were also significant. The 5yrsPS

This open, randomized (1 : 1), multicenter, 3-month study compared a dual tacrolimus plus steroids (Tac / steroids) regimen with a steroid-free immunosuppressive regimen of tacrolimus following daclizumab induction therapy (Tac / Dac) in adult liver transplant recipients. The full analysis set comprised 347 patients in the Tac / steroids group and 351 in the Tac / Dac group. Mean tacrolimus dose during month 3 was 0.11 mg/kg/day in both groups; mean whole-blood trough levels during month 3 were 10.9 ng/mL (Tac / steroids) and 10.6 ng/mL (Tac / Dac). The incidence of biopsy-confirmed acute rejection that required treatment was similar in both groups: 26.5% in the Tac / steroids group and 25.4% in the Tac / Dac group (P = .727). However, the incidence of biopsy-confirmed corticosteroid-resistant acute rejection was higher in the Tac / steroids group than in the Tac / Dac group (6.3 vs. 2.8%; P = .027). Kaplan-Meier estimates of graft survival (92.2 vs. 90.5%) and patient survival (94.5 vs. 93.7%) were similar in both groups. While also the overall adverse event profiles were similar, the incidences of diabetes mellitus (15.3 vs. 5.7%, respectively; P < .001) and cytomegalovirus infection (11.5 vs. 5.1%, respectively; P = .002) were higher in the Tac / steroids group compared with the Tac / Dac group. Mean cholesterol levels increased by 16% in the Tac / steroids group, but were unchanged in the Tac / Dac group during the study. In conclusion, tacrolimus monotherapy following daclizumab induction is an effective and safe regimen, with an advantage over concomitant steroid-maintenance therapy in terms of a lower incidence of diabetes and viral infection, and a lower incidence of steroid-resistant acute rejection.

Background: Transcatheter arterial chemoembolisation (TACE) is the treatment of choice for intermediate stage hepatocellular carcinoma (HCC). Doxorubicin-loaded drug-eluting beads (DEB)-TACE is expected to improve the performance of conventional TACE (cTACE). The aim of this study was to compare DEB-TACE with cTACE in terms of time-to-tumour progression (TTP), adverse events (AEs), and 2-year survival. Methods: Patients were randomised one-to-one to undergo cTACE or DEB-TACE and followed-up for at least 2 years or until death. Transcatheter arterial chemoembolisation was repeated ‘on-demand'. Results: We enrolled 177 patients: 89 underwent DEB-TACE and 88 cTACE. The median number of procedures was 2 in each arm, and the in-hospital stay was 3 and 4 days, respectively (P=0.323). No differences were found in local and overall tumour response. The median TTP was 9 months in both arms. The AE incidence and severity did not differ between the arms, except for post-procedural pain, more frequent and severe after cTACE (P

Summary Background Mortality after liver transplantation depends on heterogeneous recipient and donor factors. Our aim was to assess risk of death and to develop models to help predict mortality after liver transplantation. Methods We analysed data from 34 664 first adult liver transplants from the European Liver Transplant Registry to identify factors associated with mortality at 3-months (n=21 605 in training dataset) and 12-months (n=18 852 in training dataset) after transplantation. We used multivariable logistic regression models to generate mortality scores for each individual, and assessed model discrimination and calibration on an independent validation dataset (n=9489 for 3-month model and n=8313 for 12-month model). Findings 2540 of 21 605 (12%) individuals in the 3-month training sample had died by 3 months. Compared with those transplanted in 2000–03, those transplanted earlier had a higher risk of death. Increased mortality at 3-months post-transplantation was associated with acute liver failure (adjusted odds ratio 1·61), donor age older than 60 years (1·16), compatible (1·22) or incompatible (2·07) donor–recipient blood group, older recipient age (1·12 per 5 years), split or reduced graft (1·96), total ischaemia time of longer than 13 h (1·38), and low United Network for Organ Sharing score (score 1: 2·43; score 2: 1·67). However, cirrhosis with hepatocellular carcinoma, alcohol cirrhosis, hepatitis C or primary biliary cirrhosis, donor age 40 years or younger, or less, hepatitis B, and larger size of transplant centre (⩾70 transplants per year) were associated with improved early outcomes. The 3-month mortality score discriminated well between those who did and did not die in the validation sample (C statistic=0·688). We noted similar findings for 12-month mortality, although deaths were generally underestimated at this timepoint. Interpretation The 3-month and 12-month mortality models can be effectively used to assess outcomes both within and between centres. Furthermore, the models provide a means of assessing the risk of post-transplantation mortality, giving clinicians important data on which to base strategic decisions about transplant policy in particular individuals or groups.

In patients with terminal Hepatitis B Virus-related liver diseases, liver transplantation carries a consistent risk of Hepatitis B Virus recrudescence in the graft. In the attempt to reduce the reinfection rate with antiviral therapy, we studied a total of 16 viraemic patients.Twelve patients received Ganciclovir, starting 4-67 days (mean 25 days) before transplantation and prolonged for 10 days after transplantation; four patients were treated with Lactosaminated Arabinoside-Monophosphate 6 hours before surgery and prolonged for 28 days after surgery. All received hepatitis B immunoglobulins.At transplantation, HBV-DNA had decreased to about 10(4) virus/ml (as assessed by the polymerase chain reaction assay) in 10 of the 12 patients treated with Ganciclovir. Of these patients, 4 died perioperatively from causes unrelated to Hepatitis B Virus reinfection. Of the eight survivors, only the patient who maintained a titre of 10(6) virus/ml at the time of transplantation developed viral recurrence 4 months after surgery. Before transplantation, 2 of the patients treated with Lactosaminated Arabinoside-Monophosphate had a viraemic load of 10(6) and 2 of 10(4) virus/ml. In all cases, viraemia became undetectable at the end of therapy. None died and Hepatitis B Virus recurred 2 months after transplantation in one. The overall rate of Hepatitis B Virus recurrence was 16.6%. The recurrence rate decreased to 9% in patients in whom the viraemic load decreased to around 10(4) virus/ml following treatment, compared to an overall recurrence rate of 50% in our historical series of patients transplanted for Hepatitis B Virus-related cirrhosis.Antiviral therapy was effective in decreasing the risk of Hepatitis B Virus reinfection of the liver graft by decreasing the viral load before surgery.

Posthepatectomy liver failure (PHLF) is the third most frequent complication and the major cause of postoperative mortality after resection of colorectal cancer liver metastases (CRLM). In case of synchronous resectable CRLM, it is still unclear if surgical strategy (simultaneous versus staged resection of colorectal cancer and hepatic metastases) influences the incidence and severity of PHLF. The aim of this study was to evaluate the impact of surgical strategy on PHLF and on the early and long-term outcome.Retrospective study on 106 consecutive patients undergoing hepatectomy for synchronous CRLM between 1997 and 2012.Of 106 patients, 46 underwent simultaneous resection and 60 had staged hepatectomy. The rate of PHLF was similar between groups (16.7% vs 15.2%; p=1) and subgroup analysis restricted to patients undergoing major hepatectomy confirmed this observation (31.8% vs 23.8%; p=0.56). Propensity-score analysis showed that preoperative total bilirubin level and the amount of intra-operative blood transfusion were independently associated with an increased risk of PHLF. Nevertheless, the risk of severe PHLF (grade B - C) was increased in patients who underwent simultaneous resection and major hepatectomy (OR: 4.82; p=0.035). No significant differences were observed in severe (Dindo - Clavien 3 - 4) postoperative morbidity (23.9% vs 20.0%; p=0.64) and survival (3 and 5-year survival: 55% and 34% vs 56% and 33%; p=0.83).The risk of PHLF is not associated with surgical strategy in the treatment of synchronous CRLM. Nevertheless, the risk of severe PHLF is increased in patients undergoing simultaneous resection and major hepatectomy.

Objectives A prospective cohort study was conducted in Italy in order to describe the microbiologic aspects of colonization/infection by carbapenemase-producing Enterobacteriaceae (CPE) in donors and recipients of lung and liver transplants and the possible CPE transmission from donors to recipients. Methods Between 15 January 2014 and 14 January 2015, all recipients of solid organ transplants (SOT) at ten lung and eight liver transplantation centres and the corresponding donors were enrolled. Screening cultures to detect CPE were performed in donors, and screening and clinical cultures in recipients with a 28-day microbiologic follow-up after receipt of SOT. Detection of carbapenemase genes by PCR, genotyping by multilocus sequence typing, and pulsed-field gel electrophoresis and whole-genome sequencing were performed. Results Of 588 screened donors, 3.4% were colonized with CPE. Of the liver first transplant recipients (n = 521), 2.5% were colonized before receipt of SOT and 5% acquired CPE during follow-up. CPE colonization was higher in lung first transplant recipients (n = 111, 2.7% before SOT and 14.4% after SOT). CPE infections occurred in 1.9% and 5.3% of liver or lung recipients, respectively. CPE isolates were mostly Klebsiella pneumoniae carbapenemase (KPC)-producing K. pneumoniae belonging to CG258. Three events of donor–recipient CPE transmission, confirmed by whole-genome sequencing and/or pulsed-field gel electrophoresis, occurred in lung recipients: two involving K. pneumoniae sequence type 512 and one Verona integron-encoded metallo-β-lactamase (VIM)-producing Enterobacter aerogenes. Conclusions This study showed a low risk of donor–recipient CPE transmission, indicating that donor CPE colonization does not necessarily represent a contraindication for donation unless colonization regards the organ to be transplanted. Donor and recipient screening remains essential to prevent CPE transmission and cross-infection in transplantation centres.

To implement split liver transplantation (SLT) a mandatory-split policy has been adopted in Italy since August 2015: donors aged 18-50years at standard risk are offered for SLT, resulting in a left-lateral segment (LLS) graft for children and an extended-right graft (ERG) for adults. We aim to analyze the impact of the new mandatory-split policy on liver transplantation (LT)-waiting list and SLT outcomes, compared to old allocation policy. Between August 2015 and December 2016 out of 413 potentially “splittable” donors, 252 (61%) were proposed for SLT, of whom 53 (21%) donors were accepted for SLT whereas 101 (40.1%) were excluded because of donor characteristics and 98 (38.9%) for absence of suitable pediatric recipients. The SLT rate augmented from 6% to 8.4%. Children undergoing SLT increased from 49.3% to 65.8% (P=.009) and the pediatric LT-waiting list time dropped (229 [10-2121] vs 80 [12-2503] days [P=.045]). The pediatric (4.5% vs 2.5% [P=.398]) and adult (9.7% to 5.2% [P20kg (HR=5.113, P=.048) in LLS, and ischemic time >8hours (HR=2.475, P=.048) in ERG were identified as predictors of graft failure. A national mandatory-split policy maximizes the SLT donor resources, whose selection criteria can be safely expanded, providing favorable impact on the pediatric LT-waiting list and priority for adult sick LT candidates.

Background: To generate a robust predictive model of Early (3 months) Graft Loss after liver transplantation, we used a Bayesian approach to combine evidence from a prospective European cohort (Liver-Match) and the United Network for Organ Sharing registry. Methods: Liver-Match included 1480 consecutive primary liver transplants performed from 2007 to 2009 and the United Network for Organ Sharing a time-matched series of 9740 transplants. There were 173 and 706 Early Graft Loss, respectively. Multivariate analysis identified as significant predictors of Early Graft Loss: donor age, donation after cardiac death, cold ischaemia time, donor body mass index and height, recipient creatinine, bilirubin, disease aetiology, prior upper abdominal surgery and portal thrombosis. Results: A Bayesian Cox model was fitted to Liver-Match data using the United Network for Organ Sharing findings as prior information, allowing to generate an Early Graft Loss-Donor Risk Index and an Early Graft Loss-Recipient Risk Index. A Donor-Recipient Allocation Model, obtained by adding Early Graft Loss-Donor Risk Index to Early Graft Loss-Recipient Risk Index, was then validated in a distinct United Network for Organ Sharing (year 2010) cohort including 2964 transplants. Donor-Recipient Allocation Model updating using the independent Turin Transplant Centre dataset, allowed to predict Early Graft Loss with good accuracy (c-statistic: 0.76). Conclusion: Donor-Recipient Allocation Model allows a reliable donor and recipient-based Early Graft Loss prediction. The Bayesian approach permits to adapt the original Donor-Recipient Allocation Model by incorporating evidence from other cohorts, resulting in significantly improved predictive capability. © 2013 Editrice Gastroenterologica Italiana S.r.l.

BACKGROUND: The Liver Match is an observational cohort study that prospectively enrolled liver transplantations performed at 20 out of 21 Italian Transplant Centres between June 2007 and May 2009. Aim of the study is to investigate the impact of donor/recipient matching on outcomes. In this report we describe the study methodology and provide a cross-sectional description of donor and recipient characteristics and of graft allocation. METHODS: Adult primary transplants performed with deceased heart-beating donors were included. Relevant information on donors and recipients, organ procurement and allocation were prospectively entered in an ad hoc database within the National Transplant Centre web-based Network. Data were blindly analysed by an independent Biostatistical Board. RESULTS: The study enrolled 1530 donor/recipient matches. Median donor age was 56 years. Female donors (n = 681, median 58, range 12-92 years) were older than males (n = 849, median 53, range 2-97 years, p < 0.0001). Donors older than 60 years were 42.2%, including 4.2% octogenarians. Brain death was due to non-traumatic causes in 1126 (73.6%) cases. Half of the donor population was overweight, 10.1% was obese and 7.6% diabetic. Hepatitis B core antibody (HBcAb) was present in 245 (16.0%) donors. The median Donor Risk Index (DRI) was 1.57 (>1.7 in 35.8%). The median cold ischaemia time was 7.3h (≥ 10 in 10.6%). Median age of recipients was 54 years, and 77.7% were males. Hepatocellular carcinoma (HCC) was the most frequent indication overall (44.4%), being a coindication in roughly 1/3 of cases, followed by viral cirrhosis without HCC (28.2%) and alcoholic cirrhosis without HCC (10.2%). Hepatitis C virus infection (with or without HCC) was the most frequent etiologic factor (45.9% of the whole population and 71.4% of viral-related cirrhosis), yet hepatitis B virus infection accounted for 28.6% of viral-related cirrhosis, and HBcAb positivity was found in 49.7% of recipients. The median Model for End Stage Liver Disease (MELD) at transplant was 12 in patients with HCC and 18 in those without. Multivariate analysis showed a slight but significant inverse association between DRI and MELD at transplant. CONCLUSIONS: The deceased donor population in Italy has a high-risk profile compared to other countries, mainly due to older donor age. Almost half of the grafts are transplanted in recipients with HCC. Higher risk donors tend to be preferentially allocated to recipients with HCC, who are usually less ill and older. No other relevant allocation strategy is currently adopted at national level.

Despite the worldwide acceptance of split liver transplantation (SLT) as a strategy to expand a limited donor pool, problems still exist in its widespread application.1 The technique of “conventional” SLT divides the liver of a heart-beating donor into an extended right graft (ERG) and a left lateral segment graft (LLS), including Couinaud segments I, IV–VIII, and segments II–III, respectively.2,3 Recent single-center series of either in situ or ex situ SLT reported results comparable to whole liver transplantation (WLT).3–16 The ideal split liver donor should be between 14 and 50 years of age, with good liver function, serum sodium level

BACKGROUND: Hepatitis C virus (HCV) recurrence in HCV+ liver transplant recipients is almost inevitable and may be promoted by immunosuppression. We compared the amount of liver damage with regard to usage of steroids and basiliximab. METHODS: A total of 140 HCV+ adult liver transplant recipients were randomly allocated to basiliximab + steroids or basiliximab + placebo (plus cyclosporine and azathioprine). Primary endpoint: hepatitis C histological recurrence (liver damage as for Ishak grading score >or=8 by biopsy at 12 months); secondary endpoints: treatment failure (death, graft loss, patient withdrawal), biopsy proven acute rejection (BPAR), treated acute rejection (tAR), allograft and patient survival rates at 12 months. RESULTS: Any significant difference has been observed in the 12-month hepatitis C histological recurrence rate (41.2% basiliximab + steroids, 37.5% basiliximab + placebo, P = 0.354). The treatment failure rate was significantly higher in basiliximab + steroids (28.8%) than in basiliximab + placebo (15.6%), P = 0.03; the combination test for the evaluation of the joint hypothesis resulted in a borderline nonsignificant overall result (P = 0.059). BPAR rate was significantly lower in the group treated with steroids (24.3% basiliximab + steroids, 39.4% basiliximab + placebo, P = 0.04), while the tAR rate was similar (29.7% basiliximab + steroids and 37.9% basiliximab + placebo). Any significant differences in 1-year graft and patient survival rates have been observed (72.9% and 84.8% basiliximab+steroids; 81.5% and 89.0% basiliximab + placebo). CONCLUSIONS: Results suggest that steroid-free therapy is associated with a significantly lower treatment failure rate, although histological recurrence rate of hepatitis C is similar in the two groups. This benefit is not offset by an evident increase in graft rejection rate requiring treatment.

Summary Background Indications for liver transplantation for hepatocellular carcinoma are evolving and so-called expanded criteria remain debated. Locoregional therapies are able to downstage hepatocellular carcinoma from beyond to within the Milan criteria. We aimed to investigate the efficacy of liver transplantation after successful hepatocellular carcinoma downstaging. Methods We did an open-label, multicentre, randomised, controlled trial designed in two phases, 2b and 3, at nine Italian tertiary care and transplantation centres. Patients aged 18–65 years with hepatocellular carcinoma beyond the Milan criteria, absence of macrovascular invasion or extrahepatic spread, 5-year estimated post-transplantation survival of at least 50%, and good liver function (Child-Pugh A-B7) were recruited and underwent tumour downstaging with locoregional, surgical, or systemic therapies according to multidisciplinary decision. After an observation period of 3 months, during which sorafenib was allowed, patients with partial or complete responses according to modified Response Evaluation Criteria in Solid Tumors were randomly assigned (1:1) by an interactive web-response system to liver transplantation or non-transplantation therapies (control group). A block randomisation (block size of 2), stratified by centre and compliance to sorafenib treatment, was applied. Liver transplantation was done with whole or split organs procured from brain-dead donors. The control group received sequences of locoregional and systemic treatment at the time of demonstrated tumour progression. The primary outcomes were 5-year tumour event-free survival for phase 2b and overall survival for phase 3. Analyses were by intention to treat. Organ allocation policy changed during the course of the study and restricted patient accrual to 4 years. This trial is registered with ClinicalTrials.gov , NCT01387503 . Findings Between March 1, 2011, and March 31, 2015, 74 patients were enrolled. Median duration of downstaging was 6 months (IQR 4–11). 29 patients dropped out before randomisation and 45 were randomly assigned: 23 to the transplantation group versus 22 to the control group. At data cutoff on July 31, 2019, median follow-up was 71 months (IQR 60–85). 5-year tumour event-free survival was 76·8% (95% CI 60·8–96·9) in the transplantation group versus 18·3% (7·1–47·0) in the control group (hazard ratio [HR] 0·20, 95% CI 0·07–0·57; p=0·003). 5-year overall survival was 77·5% (95% CI 61·9–97·1) in the transplantation group versus 31·2% (16·6–58·5) in the control group (HR 0·32, 95% CI 0·11–0·92; p=0·035). The most common registered grade 3–4 serious adverse events were hepatitis C virus recurrence (three [13%] of 23 patients) and acute transplant rejection (two [9%]) in the transplantation group, and post-embolisation syndrome (two [9%] of 22 patients) in the control group. Treatment-related deaths occurred in four patients: two (8%) of 23 patients in the transplantation group (myocardial infarction and multi-organ failure) versus two (9%) of 22 patients in the control group (liver decompensation). Interpretation Although results must be interpreted with caution owing to the early closing of the trial, after effective and sustained downstaging of eligible hepatocellular carcinomas beyond the Milan criteria, liver transplantation improved tumour event-free survival and overall survival compared with non-transplantation therapies Post-downstaging tumour response could contribute to the expansion of hepatocellular carcinoma transplantation criteria.

Background: The most appropriate endo-therapeutic approach to biliary anastomotic strictures is yet to be defined. Aim: To retrospectively report on the endo-therapy of duct-to-duct anastomotic strictures during 2013 in Italy. Methods: Data were collected from 16 Endoscopy Units at the Italian Liver Transplantation Centers (BASALT study group). Results: Complete endo-therapy and follow-up data are available for 181 patients: 101 treated with plastic multistenting, 26 with fully covered self-expandable metal stenting and 54 with single stenting. Radiological success was achieved for 145 patients (80%), that is, 88% of plastic multistenting, 88% of self-expandable metal stenting and 61% of single stenting (P

The purpose of this registry study was to provide an overview of trends and results of liver transplantation (LT) in Europe from 1968 to 2016. These data on LT were collected prospectively from 169 centers from 32 countries, in the European Liver Transplant Registry (ELTR) beginning in 1968. This overview provides epidemiological data, as well as information on evolution of techniques, and outcomes in LT in Europe over more than five decades; something that cannot be obtained from only a single center experience. ispartof: TRANSPLANT INTERNATIONAL vol:31 issue:12 pages:1293-1317 ispartof: location:Switzerland status: published

Early everolimus (EVR) introduction and tacrolimus (TAC) minimization after liver transplantation may represent a novel immunosuppressant approach. This phase 2, multicenter, randomized, open-label trial evaluated the safety and efficacy of early EVR initiation. Patients treated with corticosteroids, TAC, and basiliximab were randomized (2:1) to receive EVR (1.5 mg twice daily) on day 8 and to gradually minimize or withdraw TAC when EVR was stable at >5 ng/mL or to continue TAC at 6-12 ng/mL. The primary endpoint was the proportion of treated biopsy-proven acute rejection (tBPAR)–free patients at 3 months after transplant. As secondary endpoints, composite tBPAR plus graft/patient loss rate, renal function, TAC discontinuation rate, and adverse events were assessed. A total of 93 patients were treated with EVR, and 47 were controls. After 3 months from transplantation, 87.1% of patients with EVR and 95.7% of controls were tBPAR-free (P = 0.09); composite endpoint-free patients with EVR were 85% (versus 94%; P = 0.15). Also at 3 months, 37.6% patients were in monotherapy with EVR, and the tBPAR rate was 11.4%. Estimated glomerular filtration rate was significantly higher with EVR, as early as 2 weeks after randomization. In the study group, higher rates of dyslipidemia (15% versus 6.4%), wound complication (18.32% versus 0%), and incisional hernia (25.8% versus 6.4%) were observed, whereas neurological disorders were more frequent in the control group (13.9% versus 31.9%; P < 0.05). In conclusion, an early EVR introduction and TAC minimization may represent a suitable approach when immediate preservation of renal function is crucial.

Background: Long-term real-world data are relatively sparse regarding recurrence of chronic hepatitis B virus (HBV) infection after liver transplantation using hepatitis B immunoglobulin (HBIg) and nucleos(t)ide analogue (NUC) prophylaxis.MAterial/Methods: Data from 371 adults transplanted for HBV-related disease at 20 European centers and given HBIg for >= 12 months +/- NUC therapy were analyzed retrospectively.Results: HBIg comprised Hepatect (R) (iv HBIgB; n=299), subcutaneous Zutectra (R) (sc HBIg, n=236), and other HBIg preparations (n=130); 93.5% received NUC therapy. Mean follow-up was 6.8 +/- 3.5 years. The primary efficacy variable, freedom from HBV recurrence, occurred in 95.7% of patients (95% CI [93.1%, 97.5%]). The observed incidence of recurrence was 16/371 (4.3%) (annual rate 0.65%); 5/16 patients with recurrence had discontinued HBIg and 7/16 had anti-HBs Conclusions: These results support the long-term use of HBIg with NUC therapy as an effective management strategy to minimize risk of HBV recurrence and virus-related complications after liver transplantation.

Hepatocellular carcinoma (HCC) in childhood differs from adult HCC because it is often associated with inherited liver disease. It is, however, unclear whether liver transplantation (LT) for HCC in childhood with or without associated inherited disease has a comparable outcome to adult HCC. On the basis of data from the European Liver Transplant Registry (ELTR), we aimed to investigate if there are differences in patient and graft survival after LT for HCC between children and adults and between patients with underlying inherited versus noninherited liver disease, respectively. We included all 175 children who underwent LT for HCC and were enrolled in ELTR between 1985 and 2012. Of these, 38 had an associated inherited liver disease. Adult HCC patients with (n = 79) and without (n = 316, matched by age, sex, and LT date) inherited liver disease served as an adult comparison population. We used multivariable piecewise Cox regression models with shared frailty terms (for LT center) to compare patient and graft survival between the different HCC groups. Survival analyses demonstrated a superior longterm survival of children with inherited liver disease when compared with children with HCC without inherited liver disease (hazard ratio [HR], 0.29; 95% CI, 0.10-0.90; P = 0.03) and adults with HCC with inherited liver disease (HR, 0.27; 95% CI, 0.06-1.25; P = 0.09). There was no survival difference between adults with and without inherited disease (HR, 1.05; 95% CI, 0.66-1.66; P = 0.84). In conclusion, the potential survival advantage of children with an HCC based on inherited disease should be acknowledged when considering transplantation and prioritization for these patients. Further prospective studies accounting for tumor size and extension at LT are necessary to fully interpret our findings. Liver Transplantation 24 246-255 2018 AASLD.

Background Liver transplantation is the most extreme form of surgical management of patients with hepatic trauma, with very limited literature data supporting its use. The aim of this study was to assess the results of liver transplantation for hepatic trauma. Methods This retrospective analysis based on European Liver Transplant Registry comprised data of 73 recipients of liver transplantation for hepatic trauma performed in 37 centers in the period between 1987 and 2013. Mortality and graft loss rates at 90 days were set as primary and secondary outcome measures, respectively. Results Mortality and graft loss rates at 90 days were 42.5% and 46.6%, respectively. Regarding general variables, cross-clamping without extracorporeal veno-venous bypass was the only independent risk factor for both mortality (P = 0.031) and graft loss (P = 0.034). Regarding more detailed factors, grade of liver trauma exceeding IV increased the risk of mortality (P = 0.005) and graft loss (P = 0.018). Moreover, a tendency above the level of significance was observed for the negative impact of injury severity score (ISS) on mortality (P = 0.071). The optimal cut-off for ISS was 33, with sensitivity of 60.0%, specificity of 80.0%, positive predictive value of 75.0%, and negative predictive value of 66.7%. Conclusions Liver transplantation seems to be justified in selected patients with otherwise fatal severe liver injuries, particularly in whom cross-clamping without extracorporeal bypass can be omitted. The ISS cutoff less than 33 may be useful in the selection process.

Anastomotic leaks and fistulae are well-known complications of esophagogastric surgery that occur after 10% to 30% of such operations.1-4 Treatment of these complications is challenging, surgical repair may be ineffective, and the mortality rate may be as high as 60% whatever the mode of treatment.5,6 Several endoscopic methods have been proposed as alternative, noninvasive methods of fistula closure.7-9 Placement of expandable metal stents in the esophagus has become a major method of palliation for obstructing malignant lesions and fistulas.10-12 Placement of these stents, both covered and uncovered, has occasionally been described for the management of benign esophageal strictures and fistulae.13 A case is reported here of successful treatment of an anastomotic esophagomediastinal fistula, a complication of distal esophagectomy with total gastrectomy for adenocarcinoma of the cardia, by temporary placement of a new polyester, silicone-covered, expandable stent.

BACKGROUND & AIMS: HBV-related chronic liver disease is one of the most common indications for liver transplantation (LT) in Europe. The ELTR database was used to evaluate outcomes and evolution over 20 years (01/1988 and 12/2010). METHODS: HBV transplanted patients were analysed according to indication for LT: decompensated cirrhosis (HBVdec) or hepatocellular carcinoma (HBV/HCC). These groups were compared with co-infected patients HBV/HDV (HBDV), HBV/HCV (HBCV), HBV/HDV/HCV (HBDCV); n = 16,664 and with HCV patients (n = 2452) according to LT indication. RESULTS: 5912 patients were transplanted for HBV (78% HBVdec, 22% HBV/HCC), with HBV/HCC patients who increased from 15.8% in 1988-1995 to 29.6% in 2006-2010 (p < 0.001). In HBVdec patients, 1, 3, 5, and 10 year patient and graft survival was 83%, 78%, 75%, 68%, and 80%, 74%, 71%, 64%, respectively, significantly better than HBV/HCC (84%, 73%, 68%, 61%, and 81%, 70%, 65%, 58% respectively; p = 0.001 and p = 0.026). In 2006-2010 patient and graft survival significantly improved compared to 1988-1995, both for HBVdec and HBV/HCC (each p < 0.001). A better patient and graft survival was seen in HBV/HCC patients with HBV-DNA(-) compared to HBV-DNA(+) at the time of LT (p < 0.001). Disease recurrence, as cause of death/graft loss, was significantly reduced in recent years compared to the past: currently

Background & Aims: The appropriate allocation of grafts from HBcAb positive donors in liver transplantation is crucial, yet a consensus is still lacking. Methods: We evaluated this issue within Liver Match, a prospective observational Italian study. Data from 1437 consecutive, first transplants performed in 2007-2009 using grafts from deceased heart beating donors were analyzed (median follow-up: 1040 days). Of these, 219 (15.2%) were HBcAb positive. Sixty-six HBcAb positive grafts were allocated to HBsAg positive and 153 to HBsAg negative recipients. Results: 329 graft losses occurred (22.9%): 66 (30.1%) among 219 recipients of HBcAb positive grafts, and 263 (21.6%) among 1218 recipients of HBcAb negative grafts. Graft survival was lower in recipients of HBcAb positive compared to HBcAb negative donors, with unadjusted 3-year graft survival of 0.69 (s.e. 0.032) and 0.77 (0.013), respectively (log-rank, p = 0.0047). After stratifying for recipient HBsAg status, this difference was only observed among HBsAg negative recipients (log rank, p = 0.0007), 3-year graft survival being excellent (0.88, s.e. 0.020) among HBsAg positive recipients, regardless of the HBcAb donor status (log rank, p = 0.4478). Graft loss due to de novo HBV hepatitis occurred only in one patient. At Cox regression, hazard ratios for graft loss were: MELD (1.30 per 10 units, p = 0.0002), donor HBcAb positivity (1.56, p = 0.0015), recipient HBsAg positivity (0.43, p

Background and Aim: Hepatocellular carcinoma (HCC) is a multifactorial disease driven by both genetic and epigenetic factors. Infection, inflammation and the immune response against hepatitis B virus and hepatitis C virus have been shown to play an important role in increasing cancer risk and promoting tumor development. In order to investigate the genetic component influencing HCC development, we analyzed 50 single nucleotide polymorphisms (SNP) spanning 34 different genes in 230 Italian patients affected by HCC and 230 controls. Methods: Genes were selected on the basis of their known biological function and their possible involvement in the progression or in the susceptibility to HCC was considered. SNP genotyping was performed using allelic-specific fluorescent probes. Results: For most SNP, no differences were identified between HCC patients and controls, with the exception of rs2304052, localized on the secreted protein acidic and rich in cysteine (SPARC) gene, which was significantly associated to the disease. The C allele was significantly more frequent in the HCC patients than in the healthy controls (23% vs 10%, corrected P

Portopulmonary hypertension has been reported in 2% to 9% of candidates for liver transplantation (OLT). If it is moderate to severe, it represents a contraindication to the procedure until pulmonary vasodilatative therapy has been optimized. We report the case of a 43-year-old man, scheduled for OLT due to alcoholic cirrhosis with hemosiderosis. His Model for End-Stage Liver Disease was 25 at that time. The preoperative evaluation showed a severe alteration of diffusion (pO2 68 mm Hg), without hepatopulmonary syndrome or portopulmonary hypertension (PPH) upon basal and dobutamine stress echocardiography. At the beginning of the OLT the hemodynamic profile showed mean pulmonary artery pressure (mPAP) 38 mm Hg, wedge pressure (WP) 19 mm Hg, cardiac output (CO) 9.1 L/min, pulmonary vascular resistance (PVR) 166 dyne s/cm5, transpulmonary gradient (TPG) 19 mm Hg, which lead us to promptly initiate inhaled nitric oxide (iNO) and intravenous epoprostenol 2 to 5 ng/kg/min. Upon graft reperfusion the hemodynamic profile was: mPAP 47 mm Hg, WP 23 mm Hg, CO 14.2 L/min, PVR 135 dyne s/cm5, TPG 24 mm Hg, and at the end of surgery, mPAP 39 mm Hg, WP 20 mm Hg, CO 10.6 L/min, PVR 123 dyne s/cm5, TPG 19 mm Hg. On postoperative day (POD) 3, we observed severe worsening of PPH: mPAP 60 mm Hg, WP 10 mm Hg, CO 9.8 L/min, PVR 395 dyne s/cm5, TPG 50 mm Hg even with maximal pulmonary vasodilatatory therapy (ambrisentan 5 mg, intravenous sildenafil 20 mg × 3 and epoprostenol 22 ng/kg/min, iNO). Severe acute respiratory distress syndrome (ARDS) was presents. Therefore we decided to begin veno-venous extracorporeal membrane oxygenation (v-v ECMO) to correct the hypoxic vasoconstriction. Subsequent weaning from inotropic support with iNO and epoprostenol was possible on POD 7 due to mPAP 42 mm Hg, WP 15 mm Hg, CO 7.9 L/min, PVR 273 dyne s/cm5, and TPG 27 mm Hg. On POD 11 he was weaned from ECMO due to: mPAP 40 mm Hg, WP 16 mm Hg, CO 6.5 L/min, PVR 295 dyne s/cm5 and TPG 24 mm Hg. The patient was extubated on POD 17. The cardiac catheterization 1 month after OLT showed: mPAP 28 mm Hg, WP 13 mm Hg, CO 5.4 L/min, PVR 220 dyne s/cm5 and TPG 15 mm Hg. ECMO rescue therapy in this "extreme" case allowed us to correct hypoxemia responsible for worsening of pulmonary hypertension allowing time to reach the goal of vasodilatatory therapy. © 2013 by Elsevier Inc.

Twenty-seven carriers of the hepatitis B surface antigen who underwent liver transplantation in Italy and Belgium for terminal Hepatitis delta virus (HDV) cirrhosis were investigated. In 22 of the patients, HDV infection recurred. Two patients died of coexisting HDV and hepatitis B virus (HBV) reactivation. Four patients who died of unrelated causes were found to have HDV without signs of HBV reactivation. Five patients (18%) cleared both HBV and HDV after transplantation with no evidence of hepatitis (mean follow-up, 29 months). In many surviving patients, HDV infection recurred early without signs of HBV reactivation. Disease returned in the 11 HDV-infected patients in whom HBV also recurred. Histological hepatitis did not recur during an interim of 12-33 months in the 5 HDV-infected patients in whom HBV did not return. The overall medium-term survival in patients with HDV who underwent transplantation was 77.7%. Liver transplantation offers patients with HDV a hope of cure from disease despite a high risk of reinfection. In the transplantation setting, HDV can cause subclinical infections without any apparent assistance from HBV; these infections become symptomatic only if and when HBV reactivates. Thus, HDV may not be in itself pathogenic but requires cooperation from HBV to cause the appearance of the disease.
