- Abstract
In the last years, several scoring systems based on pre- and post-transplant parameters have been developed to predict early post-LT graft function. However, some of them showed poor diagnostic abilities. This study aims to evaluate the role of the comprehensive complication index (CCI) as a useful scoring system for accurately predicting 90-day and 1-year graft loss after liver transplantation. A training set (n = 1262) and a validation set (n = 520) were obtained. The study was registered at https://www.ClinicalTrials.gov (ID: NCT03723317). CCI exhibited the best diagnostic performance for 90 days in the training (AUC = 0.94; p < 0.001) and Validation Sets (AUC = 0.77; p < 0.001) when compared to the BAR, D-MELD, MELD, and EAD scores. The cut-off value of 47.3 (third quartile) showed a diagnostic odds ratio of 48.3 and 7.0 in the two sets, respectively. As for 1-year graft loss, CCI showed good performances in the training (AUC = 0.88; p < 0.001) and validation sets (AUC = 0.75; p < 0.001). The threshold of 47.3 showed a diagnostic odds ratio of 21.0 and 5.4 in the two sets, respectively. All the other tested scores always showed AUCs < 0.70 in both the sets. CCI showed a good stratification ability in terms of graft loss rates in both the sets (log-rank p < 0.001). In the patients exceeding the CCI ninth decile, 1-year graft survival rates were only 0.7% and 23.1% in training and validation sets, respectively. CCI shows a very good diagnostic power for 90-day and 1-year graft loss in different sets of patients, indicating better accuracy with respect to other pre- and post-LT scores.Clinical Trial Notification: NCT03723317.

- Abstract
Biliary tract complications (BTCs) still burden liver transplantation (LT). The wide reporting variability highlights the absence of systematic screening. From 2000 to 2009, simultaneous liver biopsy and direct biliary visualization were prospectively performed in 242 recipients at 3 and 6 months (n = 212, 87.6%) or earlier when indicated (n = 30, 12.4%). Median follow-up was 148 (107-182) months. Seven patients (2.9%) experienced postprocedural morbidity. BTCs were initially diagnosed in 76 (31.4%) patients; 32 (42.1%) had neither clinical nor biological abnormalities. Acute cellular rejection (ACR) was present in 27 (11.2%) patients and in 6 (22.2%) BTC patients. Nine (3.7%) patients with normal initial cholangiography developed BTCs after 60 (30-135) months post-LT. BTCs directly lead to 7 (2.9%) re-transplantations and 14 (5.8%) deaths resulting in 18 (7.4%) allograft losses. Bile duct proliferation at 12-month biopsy proved an independent risk factor for graft loss (P = 0.005). Systematic biliary tract and allograft evaluation allows the incidence and extent of biliary lesions to be documented more precisely and to avoid erroneous treatment of ACR. The combination 'abnormal biliary tract-canalicular proliferation' is an indicator of worse graft outcome. BTCs are responsible for important delayed allograft and patient losses. These results underline the importance of life-long follow-up and appropriate timing for re-transplantation., (© 2020 Steunstichting ESOT. Published by John Wiley & Sons Ltd.)

- Abstract
Background: During the last decades, deceased-donor liver transplantation (DDLT) has gained a place in the therapeutic algorithm of well-selected patients harbouring non-resectable secondary liver tumors. Living-donor LT (LDLT) might represent a valuable means to further expand this indication for LT., Methods: Between 1985 and 2016, twenty-two adults were transplanted because of neuroendocrine (n = 18, 82%) and colorectal metastases (n = 4, 18%); 50% received DDLT and 50% LDLT. In LDLT, 4 (36%) right and 7 (64%) left grafts were used; the median graft-to-recipient-weight ratios (GRWR) were 1.03% (IQR 0.86%-1.30%) and 0.59% (IQR 0.51%-0.91%), respectively. Median post-LT follow-up was 64 months (IQR 17-107) in the DDLT group and 40 months (IQR 35-116) in the LDLT group. DDLT and LDLT recipients were compared in terms of overall survival, graft survival, postoperative complications and recurrence., Results: The 1- and 5-year actuarial patient survivals were 82% and 55% after DDLT, 100% and 100% after LDLT, respectively (P < 0.01). One- and 5-year actuarial graft survivals were 73% and 36% after DDLT, 91% and 91% after LDLT (P < 0.01). The outcomes of right or left LDLT were comparable. Donor hepatectomy proved safe, and one donor experienced a Clavien IIIb complication. Bilirubin peak was significantly lower after left hepatectomy compared with that after right hepatectomy [1.3 (IQR 1.2-2.2) vs. 3.3 (IQR 2.3-5.2) mg/dL; P = 0.02]., Conclusions: The more recent LDLT series compared favorably to our DDLT series in the treatment of secondary liver malignancies. The absence of portal hypertension and the use of smaller left grafts make recipient and donor surgeries safe. The safety of the procedures and lack of interference with the scarce allograft pool are expected to lead to a more frequent use of LDLT in the field of transplant oncology., (Copyright © 2019 First Affiliated Hospital, Zhejiang University School of Medicine in China.

- Abstract
Objective: The aim of the study is to evaluate whether intra-operative induction with anti-lymphocytic serum (ALS) is superior to no induction in adult liver transplantation (LT)., Background: The efficacy of ALS induction remains inconclusive in LT, because of poorly designed trials., Methods: A randomized controlled trial was conducted, including 206 adults (>15 years) and comparing tacrolimus monotherapy (TAC, n = 109) and tacrolimus plus a single, intraoperative, high-dose (9 mg/kg), rabbit anti-T-lymphocyte globulins (ATLG; n = 97). All patients had similar follow-up, including Banff-scored biopsies. Rejection was considered clinically relevant and treated if pathologic and biochemical changes were concordant. The primary endpoint was immunosuppression minimization to monotherapy; secondary endpoints were biopsy-proven rejection, clinical rejection, patient (PS) and graft (GS) survival., Results: At 1 year, 79/81 (96.3%) ATLG and 101/102 (99.0%) TAC patients were steroid-free (P = 0.585); 28 (34.6%) ATLG, and 31 (30.4%) TAC patients were on double-drug immunosuppression (P = 0.633). One-year PS and GS of ATLG and TAC patients were 84% and 92% (P = 0.260) and 76% and 90% (P = 0.054).Despite significantly a fewer day-7 moderate-to-severe acute cellular rejections (ACR) in ATLG group (10.0% vs 24.0% in TAC group, P = 0.019), cumulative proportion of patients experiencing steroid-sensitive (11.3% ATLG vs 14.7% TAC, P = 0.539), steroid-resistant (2.1% ATLG vs 3.7% TAC, P = 0.686) and chronic rejection (1.0% ATLG vs 0.9% TAC, P = 1.000) were similar. ATLG administration brought about greater hemodynamic instability and blood products use (P = 0.001)., Conclusions: At 1 year from LT, ATLG induction did not significantly affect immunosuppressive load, treated rejection, patient, and graft survival. The observed adverse events justify a modification of dosing and timing of ATLG infusion. Long-term results are required to judge the ATLG possible benefits on immunosuppressive load and tolerance induction.
