Abstract
INTRODUCTION Allograft dysfunction within the first week posttransplant is an uncommon but known complication following liver transplantation. Seventh-Day Syndrome (7DS) is a rare complication of allograft dysfunction following liver transplantation characterized by the rapid clinical deterioration of a formerly well-functioning allograft within the first week posttransplant. The etiology of 7DS is unknown, and treatment options remain limited. While cases of graft survival have been reported, the risk of mortality remains exceedingly high without urgent retransplantation. METHODS Patient data was retrospectively analyzed and a literature review performed. RESULTS We present a unique case of split liver transplantation into two pediatric recipients in which one recipient developed rapidly progressive graft failure approximately 1 week postoperatively requiring urgent retransplantation while the other recipient had an unremarkable postoperative course. Upon clinical manifestation of progressive graft failure, the patient was treated with thymoglobulin, rituximab, intravenous immunoglobulin, and plasmapheresis. Despite this, the patient's clinical status continued to decline and she underwent retransplantation 11 days following her initial liver transplant. CONCLUSION Seventh-Day Syndrome is a rare complication following liver transplantation that is associated with a high risk of morbidity and mortality. Our case adds to the limited literature on 7DS in children and is the first to report a comparative posttransplant clinical course in two recipients who received split grafts from the same donor.

Abstract
BACKGROUND Technical variant liver transplantation (TVLT) is a strategy to mitigate persistent pediatric waitlist mortality in the United States, although its implementation remains stagnant. This study investigated the relationship between TVLT utilization, transplant center volume, and graft survival. METHODS Pediatric liver transplant recipients from 2010 to 2020 (n = 5208) were analyzed using the Scientific Registry of Transplant Recipients database. Transplant centers were categorized according to the average number of pediatric liver transplants performed per year (high-volume, ≥5; low-volume, <5). Graft survival rates were compared using Kaplan-Meier curves and log-rank tests. Cox proportional hazards models were used to identify predictors of graft failure. RESULTS High-volume centers demonstrated equivalent whole liver transplant and TVLT graft survival ( P = 0.057) and significantly improved TVLT graft survival compared with low-volume centers ( P < 0.001). Transplantation at a low-volume center was significantly associated with graft failure (adjusted hazard ratio, 1.6; 95% confidence interval, 1.14-2.24; P = 0.007 in patients <12 y old and 1.8; 95% confidence interval, 1.13-2.87; P = 0.013 in patients ≥12 y old). A subset of high-volume centers with a significantly higher rate of TVLT use demonstrated a 23% reduction in waitlist mortality. CONCLUSIONS Prompt transplantation with increased TVLT utilization at high-volume centers may reduce pediatric waitlist mortality without compromising graft survival.

Abstract
It is uncertain whether prior Kasai procedures negatively impact the outcomes of liver transplantation (LT). The prior meta-analysis did not distinguish between Kasai early failure (K-EF) and late failure (K-LF). Numerous studies have been recently published; therefore, we perform a systematic review and meta-analysis. We searched PubMed and Embase databases to identify studies comparing the outcomes of biliary atresia (BA) patients undergoing primary LT versus patients with prior Kasai procedures. Subgroup analysis was done at the time of Kasai failure (early vs. late). Twenty-five studies comprising 6,408 patients receiving LT were included in the analysis. We found a statistically significant increase in one-year graft survival in K-LF versus primary liver transplant (pLT) (P = 0.0003). One-year patient survival was also increased in K-LF, although not statistically significant (P = 0.09). No difference in the one- and five-year graft and patient survival, reoperation rate, infection, and biliary complication was seen in pLT vs overall prior Kasai (K-EF and K-LF). These results suggest that prior kasai procedure does not negatively impact the outcome of LT. In addition, BA patients with prior Kasai undergoing LT later in life tend to perform better than primary liver transplants.

Long-term outcomes of pediatric liver transplantation in acute liver failure vs end-stage chronic liver disease: A retrospective observational study. World J Transplant 2023; 13:96-106. [PMID: 36968135 PMCID: PMC10037232 DOI: 10.5500/wjt.v13.i3.96] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/02/2022] [Revised: 12/22/2022] [Accepted: 03/06/2023] [Indexed: 03/16/2023] Open
Abstract
BACKGROUND Children with acute liver failure (ALF) who meet the criteria are eligible for super-urgent transplantation, whereas children with end-stage chronic liver disease (ESCLD) are usually transplanted electively. Pediatric liver transplantation (PLT) in ALF and ESCLD settings has been well described in the literature, but there are no studies comparing the outcomes in these two groups.
AIM To determine if there is a difference in post-operative complications and survival outcomes between ALF and ESCLD in PLT.
METHODS This was a retrospective observational study of all primary PLTs performed at a single center between 2000 and 2019. ALF and ESCLD groups were compared for pretransplant recipient, donor and operative parameters, and post-operative outcomes including graft and patient survival.
RESULTS Over a 20-year study period, 232 primary PLTs were performed at our center; 195 were transplanted for ESCLD and 37 were transplanted for ALF. The ALF recipients were significantly older (median 8 years vs 5.4 years; P = 0.031) and heavier (31 kg vs 21 kg; P = 0.011). Living donor grafts were used more in the ESCLD group (34 vs 0; P = 0.006). There was no difference between the two groups concerning vascular complications and rejection, but there were more bile leaks in the ESCLD group. Post-transplant patient survival was significantly higher in the ESCLD group: 1-, 5-, and 10-year survival rates were 97.9%, 93.9%, and 89.4%, respectively, compared to 78.3%, 78.3%, and 78.3% in the ALF group (P = 0.007). However, there was no difference in 1-, 5-, and 10-year graft survival between the ESCLD and ALF groups (90.7%, 82.9%, 77.3% vs 75.6%, 72.4%, and 66.9%; P = 0.119).
CONCLUSION Patient survival is inferior in ALF compared to ESCLD recipients; the main reason is death in the 1st year post-PLT in ALF group. Once the ALF children overcome the 1st year after transplant, their survival stabilizes, and they have good long-term outcomes.

Abstract
BACKGROUND With improved survival among children after transplantation, our understanding of the risk for developing other comorbidities is improving, yet little is known about the long-term risk of cardiovascular events and mortality after solid organ transplantation. METHODS In a cohort study using health administrative data, we compared cardiovascular events in children (n = 615) with liver, lung, kidney, small bowel, or multi-organ transplant at the Hospital for Sick Children, Toronto, Canada, with asthmatic children (n = 481,697) between 1996 and 2014. Outcomes included non-fatal cardiovascular events, cardiovascular death, all-cause mortality, and a composite of non-fatal and fatal cardiovascular events. Time-stratified Cox proportional hazards models were used. RESULTS Among 615 children, 317 (52%) were recipients of kidneys, 253 (41%) of livers, and the remaining 45 (7%) had lung, small bowel, or multi-organ transplants. Median follow-up was 12.1 [7.2, 16.7] years. Non-fatal incident cardiovascular events were 34 times higher among solid organ transplant recipients than non-transplanted children (incidence rate ratio (IRR) 34.4, 95% CI: 25.5, 46.4). Among transplant recipients, the cumulative incidence of non-fatal and fatal cardiovascular events was 2.3% and 13.0%, 5 and 15 years after transplantation, respectively. CONCLUSIONS Increased rate of cardiovascular events in children after transplantation highlights the need for surveillance during transition into adulthood and beyond. A higher resolution version of the Graphical abstract is available as Supplementary information.

Abstract
BACKGROUND The present study aimed at investigating long-term mortality of patients who underwent solid organ transplantation during childhood and at identifying their causes of death. METHODS A cohort of 233 pediatric solid organ transplant recipients who had a kidney, liver, or heart transplantation between 1982 and 2015 in Finland were studied. Year of birth-, sex-, and hometown-matched controls (n = 1157) were identified using the Population Register Center registry. The Causes of Death Registry was utilized to identify the causes of death. RESULTS Among the transplant recipients, there were 60 (25.8%) deaths (median follow-up 18.0 years, interquartile range of 11.0-23.0 years). Transplant recipients' risk of death was nearly 130-fold higher than that of the controls (95% CI 51.9-1784.6). The 20-year survival rates for kidney, liver, and heart recipients were 86.1% (95% CI 79.9%-92.3%), 58.5% (95% CI 46.2%-74.1%), and 61.4% (95% CI 48.1%-78.4%), respectively. The most common causes of death were cardiovascular diseases (23%), infections (22%), and malignancies (17%). There were no significant differences in survival based on sex or transplantation era. CONCLUSION The late mortality is still significantly higher among pediatric solid organ recipients in comparison with controls. Cardiovascular complications, infections, and cancers are the main causes of late mortality for all studied transplant groups. These findings emphasize the cruciality of careful monitoring of pediatric transplant recipients in order to reduce long-term mortality.

Abstract
BACKGROUND The shortage of donors' livers for pediatric recipients inspired the search for alternatives including donation after cardiac death (DCD). METHODS Retrospective review of pediatric liver transplant (PLT) using DCD grafts. Patients were divided into either FLG or RLG recipients. Pre-transplant recipient parameters, donor parameters, operative parameters, post-transplant recipient parameters, and outcomes were compared. RESULTS Overall, 14 PLTs from DCD donors between 2005 and 2018 were identified; 9 FLG and 5 RLG. All donors were Maastricht category III. Cold ischemia time was significantly longer in RLG (8.2 h vs. 6.2 h; p = .038). Recipients of FLG were significantly older (180 months vs. 7 months; p = .012) and waited significantly longer (168 days vs. 22 days; p = .012). Recipients of RLG tended to be sicker in the immediate pre-transplant period and this was reflected by the need for respiratory or renal support. There was no significant difference between groups regarding long-term complications. Three patients in each group survived more than 5 year post-transplant. One child was re-transplanted in the RLG due to portal vein thrombosis but failed to survive after re-transplant. One child from FLG also died from a non-graft-related cause. CONCLUSIONS Selected DCD grafts are an untapped source to widen the donor pool, especially for sick recipients. In absence of agreed criteria, graft and recipient selection for DCD grafts should be undertaken with caution.

Abstract
BACKGROUND Post-liver transplant thrombocytopenia is common and associated with worse outcome in adults. In children, however, the prevalence, course, and significance of post-liver transplantation thrombocytopenia are not described. Therefore, we aimed to assess this phenomenon in children. METHODS A retrospective chart review of children who underwent liver transplantation at a single tertiary center between 2004 and 2021. RESULTS Overall, 130 pediatric liver transplantations were reviewed. During the first 28 POD, thrombocytopenia was evident in 116 (89%, 95% CI 83%-94%). The median nadir platelet count was 54 K/μl (IQR: 37-99). Nadir platelet count was reached in half the patients by the third POD (IQR: 1-6). In multivariate analysis, preoperative platelet count (p = .024), volume of intraoperative packed cell transfusion (p = .045), and hypersplenism (p = .007) were associated with lower postoperative platelet counts. Patients with platelet count lower than the 50th centile on the first POD suffered from a more complicated course leading to a longer PICU admission (p = .039). CONCLUSIONS Early post-liver transplant thrombocytopenia appears to be common in children and associated with preoperative thrombocytopenia, hypersplenism, and higher intraoperative blood transfusion volumes. A low first POD platelet count (<86 K/μl) was found to be independently associated with a more complicated postoperative course, suggesting the need for heightened surveillance.

[PMID: 34994042 DOI: 10.1111/petr.14222] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/14/2021] [Revised: 12/08/2021] [Accepted: 12/24/2021] [Indexed: 10/19/2022]
Abstract
BACKGROUND Whole liver transplantation in infants <10 kg is a rare procedure with moderate outcomes (67%-79% graft survival at 1 year) and high rates of vascular complications (hepatic artery thrombosis 5-26%). METHODS Retrospective single-center analysis of whole liver transplantation in infants <10 kg and systematic review of the literature focused on survival rates and surgical complications. RESULTS Between January 2005 and December 2020, 175 liver transplantations in 173 children were performed at our center. A total of 92 (53%) children weighed less than 10 kg; 19 (21%) of them underwent WLT and constitute the study population. Median age of the recipients was 10 months (21 days-24 months) and median body weight 6.5 (3.1-9.8) kg. Median age of the donors was 5 (1-84) months and median body weight 6.1 (4-21) kg. Median donor-to-recipient body weight ratio was 1.2 (range: 0.6-4.5). Postoperatively, neither hepatic artery nor portal vein thrombosis occurred. A biliary complication occurred in 4 cases: 1 bile leak (early), 3 anastomotic stenoses (1 delayed and 2 late), and 1 non-anastomotic stenosis (late). Patient survival rate at 1, 5, and 10 years was 100%, 92%, and 92%, respectively. Overall, death-censored graft survival after 1, 5, and 10 was 100%. CONCLUSION Our results are excellent in terms of complications and graft and patient survival. This involves not only high-end surgical performance but also close interdisciplinary perioperative cooperation based on strong standard operating procedures and mainly focused on fluid management, hemostasiology, and strict monitoring of vessel patency.

Abstract
BACKGROUND Pediatric liver transplant (PLT) activity has flourished over time although with limited expansion in the graft pool. The study aims to identify pre-transplant factors that predict post-transplant patient and graft survival in the PLT population. METHODS Retrospective review of PLTs at a single tertiary transplant unit from 2000 to 2019. Univariate and multivariate analyses of pre-transplant factors were performed to identify predictors of patient and graft survival. RESULTS Two hundred and seventy-six patients received 320 PLTs. The most common cause of graft loss was hepatic artery thrombosis (n = 13, 29.6%). The most common cause of mortality was sepsis (n = 11, 29.7%). Univariate analysis showed that the following variables had a significant (p < .05) impact on patient survival: recipient age, weight, height, graft type (technical variant graft), transplant category (acute liver failure), the era of transplant, and invasive ventilation. The following variables had a significant (p < .05) impact on graft survival: recipient age, weight, height, transplant category (acute liver failure), and the era of transplant. Multivariate analysis precluded the era of transplant as the only significant factor for patient survival; patients transplanted after 2005 had significantly higher patient survival. No independent factor predicting graft survival was identified. For children transplanted after 2005, the only factor that predicted patient survival was pre-transplant invasive ventilation. CONCLUSIONS Our study suggests that the learning curve and pre-transplant invasive ventilation in the recipient have a significant impact on patient survival. The traditional view of worse outcomes of smaller PLT candidates should be changed.

Abstract
BACKGROUND Diagnosis of invasive candidiasis (IC) relies on insensitive cultures; the relative utility of fungal biomarkers in children is unclear. METHODS This multinational observational cohort study enrolled patients aged >120 days and <18 years with concern for IC from 1 January 2015 to 26 September 2019 at 25 centers. Blood collected at onset of symptoms was tested using T2Candida, Fungitell (1→3)-β-D-glucan, Platelia Candida Antigen (Ag) Plus, and Platelia Candida Antibody (Ab) Plus assays. Operating characteristics were determined for each biomarker, and assays meeting a defined threshold considered in combination. Sterile site cultures were the reference standard. RESULTS Five hundred participants were enrolled at 22 centers in 3 countries, and IC was diagnosed in 13 (2.6%). Thirteen additional blood specimens were collected and successfully spiked with Candida species, to achieve a 5.0% event rate. Valid T2Candida, Fungitell, Platelia Candida Ag Plus, and Platelia Candida Ab Plus assay results were available for 438, 467, 473, and 473 specimens, respectively. Operating characteristics for T2Candida were most optimal for detecting IC due to any Candida species, with results as follows: sensitivity, 80.0% (95% confidence interval, 59.3%-93.2%), specificity 97.1% (95.0%-98.5%), positive predictive value, 62.5% (43.7%-78.9%), and negative predictive value, 98.8% (97.2%-99.6%). Only T2Candida and Platelia Candida Ag Plus assays met the threshold for combination testing. Positive result for either yielded the following results: sensitivity, 86.4% (95% confidence interval, 65.1%- 97.1%); specificity, 94.7% (92.0%-96.7%); positive predictive value, 47.5% (31.5%-63.9%); and negative predictive value, 99.2% (97.7%-99.8%). CONCLUSIONS T2Candida alone or in combination with Platelia Candida Ag Plus may be beneficial for rapid detection of Candida species in children with concern for IC.

Abstract
Nutritional status is known to strongly predict health outcomes in people with cystic fibrosis (CF), but the prevalence of and consequences for CF children with growth failure and underweight CF adults on the liver transplant (LT) waitlist has not been delineated. We utilized UNOS registry data from 2003 to 2017 to investigate the impact of growth failure and underweight on outcomes in liver transplant candidates with CF. Almost 1 in 3 children and adults with CF had growth failure or were underweight, respectively, at listing. Body mass index under-estimated growth failure compared to height and weight z-scores for children. In multivariate analysis of children, growth failure (HR 2.1, 95% CI 1.7-2.6), and CF (HR 2.7, 95% CI 1.6-4.6, vs. Non-CF) were independent risk factors for waitlist death among children; having both increased death risk almost fourfold (SHR 3.88, 95% CI 1.42-10.58). However, among children who did receive a LT, CF was not associated with death within 1-year post-LT. Underweight adult CF candidates were less likely to receive LT, again suggesting the importance of nutritional evaluation and early intervention in this at-risk cohort.

Abstract
BACKGROUND Follow-up after pediatric liver transplantation (LTX) is challenging and needs to be refined to extend graft survival as well as general functional health and patients´ quality of life. Strategies towards individual immunosuppressive therapy seem to play a key role. Our aim was to evaluate protocol liver biopsies (PLB) as a tool in personalized follow up after pediatric LTX. PATIENTS AND METHODS Our retrospective analysis evaluates 92 PLB in clinically asymptomatic pediatric patients after LTX between 2009 and 2019. Histological findings were characterized using the Desmet scoring system. In addition to PLB, other follow-up tools like laboratory parameters, ultrasound imaging and transient elastography were evaluated. Risk factors for development of fibrosis or inflammation were analyzed. RESULTS PLB revealed a high prevalence of graft fibrosis (67.4%) and graft inflammation (47.8%). Graft inflammation was significantly (P = 0.0353*) more frequent within the first 5 years after transplantation compared to later time points. Besides conventional ultrasound, the measurement of liver stiffness using transient elastography correlate with stage of fibrosis (r = 0.567, P = <0.0001***). Presence of donor-specific anti-human leukocyte antigen antibodies in blood correlates with grade of inflammation in PLB (r = 0.6040, P = 0.0018 **). None of the patients who underwent PLB suffered from intervention-related complications. Histopathological results had an impact on clinical decision making in one-third of all patients after PLB. CONCLUSION PLB are a safe and useful tool to detect silent immune-mediated allograft injuries in the context of normal liver parameters.

Abstract
BACKGROUND Liver transplantation (LT) is a standard-of-care therapeutic modality for selected patients with life-threatening liver disease, including children. In addition to specific clinical characteristics of pediatric LT recipients due to initial liver disease (and related comorbidities) and level of liver failure, early postoperative outcome may be dependent on the surgical technique used, related to the type of organ donor and graft. Therefore, the aims of the present retrospective study from a large single centre cohort were to identify the prognostic factors for both 1-year patient and graft survival. METHODS Between October 1990 and October 2010, 151 children underwent a first LT in our centre. RESULTS The mean age was 5.3 ± 7.4 years, and the main indication was biliary atresia (BA) (49.0%). Living donor liver transplantation (LDLT) was performed in 39 cases (25.8%). Cadaveric liver graft was a whole liver in 50 cases (33.1%) and a partial liver (reduced or split) in 62 cases (41.1%). One-year patient and graft survival rates were 88.7% and 86.1%, respectively. Multivariate analysis disclosed that initial liver disease, location at time of LT, donor/recipient (D/R) delta age, early post-transplant hemodialysis and initial immunosuppression (induction) were significantly associated with patient survival and that D/R delta age, primary non-function, early post-transplant hemodialysis and initial immunosuppression (induction) were significantly associated with graft survival. CONCLUSION The results of our single-centre experience of pediatric LT emphasize that early patient and graft survivals depend on pre-operative/operative factors such as initial liver disease, D/R delta age and immunosuppressive regimen. Awareness of these factors can help in the decision making for children requiring LT.

[PMID: 34438532 PMCID: PMC8393592 DOI: 10.3390/children8080641] [Citation(s) in RCA: 10] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 06/16/2021] [Revised: 07/19/2021] [Accepted: 07/22/2021] [Indexed: 12/19/2022]
Abstract
(1) Background and Aim: Despite excellent long-term results in pediatric liver transplantation (pLTx), mortality and graft loss still are to be diminished. We aim to describe time-dependent changes and long-term outcome of a large single-center pLTx cohort and to identify independent recipient-related risk factors impairing patient and graft survival. (2) Methods: This is a retrospective single-center study analyzing all pediatric liver transplants from 1983–2020. Risk factors for mortality and graft loss were identified by univariable and multi-linear regression analysis. (3) Results: We analyzed 858 liver transplantations in 705 pediatric patients. Five-year patient/graft survival increased from 60.9%/48.0% (1983–1992) to 97.5%/86.5% (OR = 12.5; p < 0.0001/OR = 6.5; p < 0.0001) (2014–2020). Indications changed significantly over time, with a higher proportion of patients being transplanted for malignancies and metabolic disease and indications of PFIC and α1AT-deficiency declining. The era of transplantation (log7.378/9.657; p < 0.0001) and indication of acute liver failure (log = 1.944/2.667; HR = 2.015/1.772; p = 0.0114/0.002) impairs patient/graft survival significantly in the multivariate analysis. Furthermore, patient survival is worsened by re-transplantation (log = 1.755; HR = 1.744; p = 0.0176) and prolonged waiting times in high-urgency status (log = 2.588; HR = 1.073; p = 0.0026), whereas the indication of biliary atresia improved outcome (log = 1.502; HR = 0.575; p = 0.0315). Graft survival was additionally impaired by pre-existing portal vein thrombosis (log = 1.482; HR = 2.016; p = 0.0330). (4) Conclusions: Despite more complex indications, patient and graft survival after pLTx continue to improve.. Acute liver failure remains the indication with poorest outcome, and listing for high urgency liver transplantation should be considered carefully and early to keep waiting time on HU list short. Furthermore, pre-transplant portal vein thrombosis should be prevented whenever possible to improve graft survival.

Variation in immunosuppression practices among pediatric liver transplant centers-Society of Pediatric Liver Transplantation survey results. Pediatr Transplant 2021; 25:e13873. [PMID: 33026158 DOI: 10.1111/petr.13873] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/07/2020] [Revised: 07/28/2020] [Accepted: 09/11/2020] [Indexed: 11/26/2022]
Abstract
BACKGROUND Variation in IS exists among pediatric liver transplant centers. While individual centers may publish their practice paradigms, current data on practices as a whole are lacking. This study sought to ascertain the IS protocols of pediatric liver transplant centers within the SPLIT to better understand variability and similarities among peer institutions. METHODS A 27-item questionnaire was developed within the SPLIT Quality Improvement and Clinical Care Committee. The survey collected data regarding center demographics, IS practices, and treatment of acute cellular rejection. RESULTS Twenty-eight (64%) SPLIT centers responded with 22 (79%) centers performing more than 10 transplants per year and 17 (61%) following more than 100 post-transplant recipients. All centers use a written protocol, and 25 (89%) have a dedicated transplant pharmacist/PharmD. Twenty-five (89%) centers use steroids for induction alone or in combination with thymoglobulin/interleukin-2 antibodies. All centers use tacrolimus for initial maintenance therapy. Most centers have specialized protocols for ABO-incompatible transplants, recipients with renal dysfunction, autoimmune liver diseases, and liver tumors. Treatment of rejection varied but was associated with escalation in IS. CONCLUSION IS practices among pediatric liver transplant centers are similar including the use of written protocols, pharmacy involvement, steroids for induction, tacrolimus as initial IS, tacrolimus reduction/delay for renal dysfunction, and escalation of IS with rejection severity. However, other IS practices show wide variability including treatment for ABO-incompatible grafts and presumed rejection. This study serves as a foundation to guide prospective research linking IS practice to outcomes to determine best practice.

[PMID: 32767649 PMCID: PMC7867666 DOI: 10.1111/ajt.16236] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/17/2020] [Revised: 07/20/2020] [Accepted: 07/20/2020] [Indexed: 02/06/2023]
Abstract
Liver transplantation (LT) in young patients is being performed with greater frequency. We hypothesized that objective analysis of pre-, intra-, and postoperative events would help understand contributors to successful outcomes and guide transplant decision processes. We queried SPLIT registry for pediatric transplants between 2011 and 2018. Outcomes were compared for age groups: 0-<3, 3-<6, 6-<12 months, and 1-<3 years (Groups A, B, C, D respectively) and by weight categories: <5, 5-10, >10 kg; 1033 patients were available for analysis. Cholestatic disease and fulminant failure were highest in group A and those <5 kg; and biliary atresia in group C (72.8%). Group A had significantly higher life support dependence (34.6%; P < .001), listing as United Network for Organ Sharing status 1a/1b (70.4%; P < .001), and shortest wait times (P < .001). The median (interquartile range) for international normalized ratio and bilirubin were highest in group A (3.0 [2.1-3.9] and 16.7 [6.8-29.7] mg/dL) and those <5 kg (2.6 [1.8-3.4] and 13.5 [3.0-28.4] mg/dL). A pediatric end -stage liver disease score ≥40, postoperative hospital stays, rejection, and nonanastomotic biliary strictures were highest in group A with lowest survival at 93.1%. Infants 0 to <3 months and those <5 kg need more intensive care with lower survival and higher complications. Importantly, potential LT before reaching status 1a/1b and aggressive postoperative management may positively influence their outcomes.

Abstract
Liver transplantation has become the standard of care for children with end-stage liver disease. In Australia and New Zealand, there are four paediatric liver transplant units, in Sydney, Melbourne, Brisbane and Auckland. Over the past 30 years, there have been significant changes to indications for transplant, as well as medical and surgical advances. In this paper, using retrospective data from the Australia and New Zealand Liver Transplant Registry, we review 977 children (less than 16 years of age) who underwent liver transplant from 1985 to 2018. The most common indication was biliary atresia (54%), although there has been an increase in other indications, including inborn errors of metabolism, fulminant hepatic failure and malignant liver tumours. Over the past 3 decades, areas of change and innovation include: the use of 'split grafts' to enable an adult and a child to receive the same donor liver, live donation, improvements in immunosuppressive regimens and infectious prophylaxis protocols and innovative surgical techniques allowing transplantation in smaller infants. The outcomes for children who undergo liver transplant in ANZ are excellent, with current 10-year patient survival rates of 95%, comparable to other larger centres around the world.

Abstract
The Pediatric End-Stage Liver Disease (PELD) score is intended to determine priority for children awaiting liver transplantation. This study examines the impact of PELD's incorporation of "growth failure" as a threshold variable, defined as having weight or height <2 standard deviations below the age and gender norm (z-score <2). First, we demonstrate the "growth failure gap" created by PELD's current calculation methods, in which children have z-scores <2 but do not meet PELD's growth failure criteria and thus lose 6-7 PELD points. Second, we utilized United Network for Organ Sharing (UNOS) data to investigate the impact of this "growth failure gap." Among 3291 pediatric liver transplant candidates, 26% met PELD-defined growth failure, and 17% fell in the growth failure gap. Children in the growth failure gap had a higher risk of waitlist mortality than those without growth failure (adjusted subhazard ratio [SHR] 1.78, 95% confidence interval [95% CI] 1.05-3.02, P = .03). They also had a higher risk of posttransplant mortality (adjusted HR 1.55, 95% CI 1.03-2.32, P = .03). For children without PELD exception points (n = 1291), waitlist mortality risk nearly tripled for those in the gap (SHR 2.89, 95% CI 1.39-6.01, P = .005). Current methods for determining growth failure in PELD disadvantage candidates arbitrarily and increase their waitlist mortality risk. PELD should be revised to correct this disparity.

Abstract
Neonatal cholestasis is a group of rare disorders of impaired bile flow characterized by conjugated hyperbilirubinaemia in the newborn and young infant. Neonatal cholestasis is never physiological but rather is a sign of hepatobiliary and/or metabolic disorders, some of which might be fatal if not identified and treated rapidly. A step-wise timely evaluation is essential to quickly identify those causes amenable to treatment and to offer accurate prognosis. The aetiology of neonatal cholestasis now includes an expanding group of molecularly defined entities with overlapping clinical presentations. In the past two decades, our understanding of the molecular basis of many of these cholestatic diseases has improved markedly. Simultaneous next-generation sequencing for multiple genes and whole-exome or whole-genome sequencing now enable rapid and affordable molecular diagnosis for many of these disorders that cannot be directly diagnosed from standard blood tests or liver biopsy. Unfortunately, despite these advances, the aetiology and optimal therapeutic approach of the most common of these disorders, biliary atresia, remain unclear. The goals of this Review are to discuss the aetiologies, algorithms for evaluation and current and emerging therapeutic options for neonatal cholestasis.

Abstract
Objectives: To identify predisposing factors, species distribution, antifungal susceptibility, and outcome. Methods: This study is a retrospective chart review that was conducted at a children’s hospital at King Fahad Medical City, Riyadh, Kingdom of Saudi Arabia. One hundred twenty-nine children with invasive candidiasis who were admitted between January 2010 and January 2015. Results: The statistical analysis results have revealed a group of risk factors; prematurity in 37 (28.7%) of patients, low birth weight in 42 (32.6%), central venous catheter in 59 (45.7%), malignancy in 21 (16.3%), immunotherapy in 20 (15.5%), and ventilator support in 60 (46.5%). More than 2-fold mortality rate in patients who had heart vegetation (odds ratio [OR]: 2.9) and patients who had Candida isolated from their blood were more than twice as likely to die as patients with Candida isolated from other sites (OR: 2.2). A total of 48.3% of patients on ventilator died versus 26.1% who were not on ventilator (p=0.009); and 43.8% of patients in the ICU died versus only 24.5% of patients who were not in the ICU (p=0.03). Candida parapsilosis exhibited the highest mortality rate (56.2%). Conclusion: Candida albicans is the most common isolate among all Candida species. Gender, low birth weight, prolonged ICU stay, presence of vegetation, positive blood culture, and mechanical ventilation as a strong predictive risk factors for death in children with invasive candidiasis, a finding that could be applied as prophylactic indicator in critically ill children especially neonates.

Abstract
Calcium (Ca2+) signaling controls secretion in many types of cells and tissues. In the liver, Ca2+ regulates secretion in both hepatocytes, which are responsible for primary formation of bile, and cholangiocytes, which line the biliary tree and further condition the bile before it is secreted. Cholestatic liver diseases, which are characterized by impaired bile secretion, may result from impaired Ca2+ signaling mechanisms in either hepatocytes or cholangiocytes. This review will discuss the Ca2+ signaling machinery and mechanisms responsible for regulation of secretion in both hepatocytes and cholangiocytes, and the pathophysiological changes in Ca2+ signaling that can occur in each of these cell types to result in cholestasis.

Abstract
Cardiovascular disease is a frequent cause of morbidity and mortality in pediatric patients following solid organ transplant. CKD is also common in pediatric patients after a solid organ transplant, and the link between CKD and cardiovascular morbidity is strong. In this review, we examine potential etiologies to explain the risk of cardiovascular morbidity and mortality in pediatric solid organ recipients and identify targets for improving outcomes.

Abstract
The different methods in differentiating biliary atresia (BA) from non-BA-related cholestasis were evaluated in order to provide a practical basis for a rapid, early and accurate differential diagnosis of the diseases. 396 infants with cholestatic jaundice were studied prospectively during the period of May 2007 to June 2011. The liver function in all subjects was tested. All cases underwent abdominal ultrasonography and duodenal fluid examination. Most cases were subjected to hepatobiliary scintigraphy, magnetic resonance cholangiopancreatography (MRCP) and a percutaneous liver biopsy. The diagnosis of BA was finally made by cholangiography or histopathologic examination. The accuracy, sensitivity, specificity and predictive values of these various methods were compared. 178 patients (108 males and 70 females with a mean age of 58±30 days) were diagnosed as having BA. 218 patients (136 males and 82 females with a mean age of 61 ±24 days) were diagnosed as having non-BA etiologies of cholestasis jaundice during the follow-up period in which jaundice faded after treatment with medical therapy. For diagnosis of BA, clinical evaluation, hepatomegaly, stool color, serum gamma-glutamyltranspeptidase (GGT), duodenal juice color, bile acid in duodenal juice, ultrasonography (gallbladder), ultrasonography (griangular cord or strip-apparent hyperechoic foci), hepatobiliary scintigraphy, MRCP, liver biopsy had an accuracy of 76.0%, 51.8%, 84.3%, 70.0%, 92.4%, 98.0%, 90.4%, 67.2%, 85.3%, 83.2% and 96.6%, a sensitivity of 83.1%, 87.6%, 96.1%, 73.7%, 90.4%, 100%, 92.7%, 27.5%, 100%, 89.0% and 97.4%, a specificity of 70.2%, 77.5%, 74.8%, 67.0%, 94.0%, 96.3%, 88.5%, 99.5%, 73.3%, 75.4% and 94.3%, a positive predictive value of 69.0%, 72.6%, 75.7%, 64.6%, 92.5%, 95.7%, 86.8%, 98.0%, 75.4%, 82.6% and 98.0%, and a negative predictive value of 83.6%, 8.5%, 95.9%, 75.7%, 92.3%, 100%, 84.2%, 93.7%, 100%, 84.0% and 92.6%, respectively. It was concluded that all the differential diagnosis methods are useful. The test for duodenal drainage and elements is fast and accurate. It is helpful in the differential diagnosis of BA and non-BA etiologies of cholestasis. It shows good practical value clinically.

Abstract
BACKGROUND Antibody drugs have been used to treat steroid-resistant rejection (SRR) after liver transplantation. Although anti-thymocyte globulin has been used for SRR after liver transplantation in place of muromonab-CD3 since 2011 in Japan, the effectiveness of anti-thymocyte globulin after pediatric living-donor liver transplantation (LDLT) has not yet been reported. The aim of this study was to evaluate the effectiveness of antibody drug treatment for SRR after pediatric LDLT in our single center. METHODS Between May 2001 and December 2013, 220 pediatric LDLTs were performed. Initial immunosuppression after LDLT included tacrolimus and methylprednisolone therapy. Acute rejection was diagnosed by use of a liver biopsy and the administration of steroid pulse treatment, and SRR was defined as acute rejection refractory to the steroid pulse treatment. RESULTS Acute rejection and SRR occurred in 74 (33.6%) and 16 patients (7.3%), respectively. The graft survival rates of non-SRR and SRR were 92.4% and 87.5%, respectively (P = .464). The median concentration of alanine aminotransferase before and after the administration of antibody drug was 193.5 mU/mL (range, 8-508) and 78 mU/mL (range, 9-655), respectively (P = .012). The median rejection activity index before and after the administration of antibody drugs was 5 (range, 2-9) and 1 (range, 0-9), respectively (P = .004). After antibody drug treatment, 12 patients had cytomegalovirus infections, 2 patients had Epstein-Barr virus infections, 3 patients had respiratory infections, and 1 patient had encephalitis. The cause of death in 1 patient with SRR was recurrence of infant fulminant hepatic failure. CONCLUSIONS Antibody drug treatment for SRR after pediatric LDLT is safe and effective.

Abstract
Intraoperative transfusions seem associated with patient death and graft failure after PLTx. A retrospective analysis of recipients' and donors' characteristics and transplantation data in a cohort of patients undergoing PLTx from 2002 to 2009 at the Bergamo General Hospital was performed. A two-stage hierarchical Cox proportional hazard regression with forward stepwise selection was used to identify the main risk factors for major complications. In addition, propensity score analysis was used to adjust risk estimates for possible selection biases in the use of blood products. Over the 12-year period, 232 pediatric cirrhotic patients underwent PLTx. One-year patient and graft survival rates were 92.3% and 83.7%, respectively. The Kaplan-Meier shows that the main decrease in both graft and patient survival occurs during the first months post-transplantation. At the same time, it appears that most of the complications occur during the first month post-transplantation. One-month and 1-year patient complication-free survival rates were 24.8% and 12.1%, respectively. Our study shows that intraoperative red blood cells and platelet transfusions are independent risk factors for developing one or more major complications in the first year after PLTx. Decreasing major complications will improve the health status and overall long-term patient survival after pediatric PLTx.

Abstract
BACKGROUND We evaluated liver transplantation waitlist and posttransplantation outcomes in those aged 18 to 24 years compared with both younger (0-17 years) and older (25-34 years) registrants and recipients. METHODS Using national data from the United Network for Organ Sharing, competing risk, Cox regression and Kaplan-Meier analyses were performed on first-time liver transplant registrants (n = 13 979) and recipients (n = 8718) ages 0 to 34 years between 2002 and 2015. RESULTS Nonstatus 1A registrants, registrants aged 0 to 17 and 25 to 34 years were less likely to experience dropout from the waiting list compared with those aged 18 to 24 years (adjusted hazard ratio, 0-5 years = 0.36; 6-11 = 0.29; 12-17 = 0.48; 18-24 = 1.00; 25-34 = 0.82). Although there was no difference in risk of graft failure across all age groups, both younger and older age groups had significantly lower risk of posttransplant mortality compared with those aged 18 to 24 years (adjusted hazard ratio, for 0-5 years = 0.53, 6-11 = 0.48, 12-17 = 0.70, 18-24 = 1.00, 25-34 = 0.77). This may be related to lower likelihood of retransplantation after graft failure in those aged 18 to 24 years. CONCLUSIONS This national registry study demonstrates for the first time poorer waitlist and postliver transplant outcomes in young adults ages 18 to 24 years at the time of listing and transplantation compared to older and younger age groups. Given the potential survival benefit in transplanting young adults and the shortage of solid organs for transplant, future studies are critical to identify and target modifiable risk factors to improve waitlist and long-term posttransplant outcomes in 18- to 24-year-old registrants and recipients.

Abstract
Biliary atresia (BA) is the most common indication for LT in children. We investigated whether this diagnosis per se, compared to other chronic liver diseases (OCLD), had an influence on patient survival. Data from 421 Scandinavian children, 194 with BA and 227 with OCLD, listed for LT between 1990 and 2010 were analyzed. The intention-to-treat survival and influencing risk factors were studied. Patients with BA had higher risk of death after listing than patients with OCLD. The youngest (<1 year) and smallest (<10 kg) children with the highest bilirubin (>510 μmol/L), highest INR (>1.6), and highest PELD score (>20) listed during 1990s had the worst outcome. Given the same PELD score, patients with BA had higher risk of death than patients with OCLD. For adolescents, low weight/BMI was the only prognostic marker. Impaired intention-to-treat survival in patients with BA was mainly explained by more advanced liver disease in younger ages and higher proportion of young children in the BA group rather than diagnosis per se. PELD score predicted death, but seemed to underestimate the severity of liver disease in patients with BA. Poor nutritional status and severe cholestasis had negative impact on survival, supporting the "sickest children first" allocation policy and correction of malnutrition before surgery.

Abstract
BACKGROUND Vascular complications following pediatric liver transplantation occur in 8-10% of cases, and no continuous, non-invasive monitoring for this problem exists. Near infrared spectroscopy (NIRS) allows non-invasive, continuous, transcutaneous assessment of hemoglobin oxygenation (StO2 ) 1-4 cm below the skin surface. AIMS We hypothesized that transcutaneous NIRS would be able to detect severe hepatic ischemia, and tested this in an animal model using 15-20 kg and 5-7 kg juvenile pigs. MATERIALS AND METHODS Direct liver surface and transcutaneous hepatic tissue hemoglobin oxygen saturation (StO2 ) were measured during occlusions of the hepatic artery and portal vein. Changes in hepatic delivery of oxygen (HepDO2 ) were calculated for each ischemic challenge and compared to changes in direct liver surface (DirHepStO2 ) and transcutaneous liver StO2 measurements (CutHepStO2 ). RESULTS In the 15-20 kg animals during complete occlusion, CutHepStO2 decreased by 6.0(±4.9)%, whilst DirHepStO2 decreased by 83.7(±7.2)%. In the 5-7 kg animals during complete occlusion, CutHepStO2 decreased by 27.4(±8.5)%, whilst DirHepStO2 decreased by 82.8(±4.6)%. CONCLUSION Transcutaneous hepatic StO2 monitoring cannot reliably detect severe hepatic ischemia in a juvenile porcine model, although a stronger and potentially useful signal is seen in 5-7 kg pigs. Trials of this technology should be currently restricted to situations where the organ is less than 1 cm from the skin surface, corresponding to infants of <10 kg.

Abstract
Drug-induced gingival overgrowth (GO) has been associated with phenytoin, cyclosporine, and calcium channel blocker therapies. This study reports the case of an 11-year-old girl who was referred for evaluation of GO, which had occurred over the last 6 months. Her medical history included a liver transplant due to biliary atresia 3 years ago, immunosuppressive therapy, and hypertension, which is why she was started on a daily intake of amlodipine. The intraoral examination showed generalized GO, and the treatment consisted of a gingivectomy. Subsequently, amlodipine was replaced with captopril and oral hygiene instructions. There was no recurrence of GO after 28 months of follow-up. Although GO may be related to the chronic use of amlodipine, such an association is uncommon in pediatrics, and the treatment consists of the replacement of medication combined with a surgical approach and plaque control.

Abstract
Liver transplantation (LT) is an important component in the therapeutic armamentarium of managing end-stage liver disease. In North American children, biliary atresia remains the most common indication for LT compared to hepatitis C in adults, while hepatoblastoma is the most common liver tumor requiring LT, versus Hepatocellular carcinoma in adults. Rejection, lymphoproliferative disease, renal insufficiency, metabolic syndrome, recurrent disease, 'de novo' autoimmune hepatitis and malignancy require careful surveillance and prompt action in adults and children after LT. In children, specific attention to EBV viremia, growth, development, adherence and transition to the adult services is also required. Antibody mediated rejection and screening for donor specific antibodies is becoming important in managing liver graft dysfunction. Biomarkers to identify and predict tolerance are being developed. Machine perfusion and stem cells (iPS) to synthesize organs are generating interest and are a focus for research.

Abstract
OBJECTIVE The objective of the present study was to report on the health-related quality of life (HRQOL) of infants with chronic liver disease using the PedsQL (Pediatric Quality of Life Inventory) Infant Scales. METHODS The 36-item (ages 1-12 months) and 45-item (ages 13-24 months) PedsQL Infant Scales (physical functioning, physical symptoms, emotional functioning, social functioning, cognitive functioning) were completed by 50 parents of infants with chronic liver disease. RESULTS Infants ages 1 to 12 months had significantly lower HRQOL scores compared with a matched healthy sample. Infants 13 to 24 months trended to lower physical HRQOL scores that did not reach statistical significance. Recent hospitalizations had an impact on the majority of HRQOL subscales, as did ascites, and failure to thrive. CONCLUSIONS Infants ages 1 to 12 months with chronic liver disease demonstrate lower HRQOL compared with healthy children with physical subscales being most severely affected. The PedsQL Infant Scales allow the definition of HRQOL during a critical period of an infants' development that has been heretofore difficult to measure.

Abstract
Pediatric patients present with differing underlying conditions and cytotoxic therapeutic protocols, so the differing epidemiology of invasive candidiasis in children versus adults is not surprising. Understanding the Candida species epidemiology is critical, as we often begin empiric therapy or therapy before antifungal susceptibilities are known. Reports with newer molecular diagnostic assays for invasive candidiasis are rare and require more study to develop firm pediatric-specific guidance. Antifungal treatment of pediatric candidiasis is reviewed in the context of larger epidemiologic studies and the few trials completed to date.

Abstract
This study analyzed how features of a liver graft and the technique of biliary reconstruction interact to affect biliary complications in pediatric liver transplantation. A retrospective analysis was performed of data collected from 2001 to 2011 in a single high-volume North American pediatric transplant center. The study cohort comprised 173 pediatric recipients, 75 living donor (LD) and 98 deceased donor (DD) recipients. The median follow-up was 70 months. Twenty-nine (16.7%) patients suffered a biliary complication. The majority of leaks (9/12, 75.0%) and the majority of strictures (18/22, 81.8%) were anastomotic. There was no difference in the rate of biliary complications associated with DD (18.4%) and LD (14.7%) grafts (P = 0.55). Roux-en-Y (RY) reconstruction was associated with a significantly lower rate of biliary complications compared to duct-to-duct reconstruction (13.3% versus 28.2%, respectively; P = 0.048). RY anastomosis was the only significant factor protecting from biliary complications in our population (hazard ratio, 0.30; 95% confidence interval, 0.1-0.85). The leaks were managed primarily by relaparotomy (10/12, 83.3%), and the majority of strictures were managed by percutaneous biliary intervention (14/22, 63.6%). Patients suffering biliary complications had inferior graft survival (P = 0.04) at 1, 5, and 10 years compared to patients without biliary complications. Our analysis demonstrates a lower incidence of biliary complications with RY biliary reconstruction, and patients with biliary complications have decreased graft survival.

Abstract
A prognostic index to predict survival after liver transplantation could address several clinical needs. Here, we devised a scoring system that predicts recipient survival after pediatric liver transplantation. We used univariate and multivariate analysis on 4565 pediatric liver transplant recipients data and identified independent recipient and donor risk factors for posttransplant mortality at 3 months. Multiple imputation was used to account for missing variables. We identified five factors as significant predictors of recipient mortality after pediatric liver transplantation: two previous transplants (OR 5.88, CI 2.88-12.01), one previous transplant (OR 2.54, CI 1.75-3.68), life support (OR 3.68, CI 2.39-5.67), renal insufficiency (OR 2.66, CI 1.84-3.84), recipient weight under 6 kilograms (OR 1.67, CI 1.12-2.36) and cadaveric technical variant allograft (OR 1.38, CI 1.03-1.83). The Survival Outcomes Following Pediatric Liver Transplant score assigns weighted risk points to each of these factors in a scoring system to predict 3-month recipient survival after liver transplantation with a C-statistic of 0.74. Although quite accurate when compared with other posttransplant survival models, we would not advocate individual clinical application of the index.

Abstract
An IL-2 receptor antagonist, basiliximab, decreases the frequency of ACR in liver transplant (LT) recipients as induction therapy. The aim of this study was to evaluate the effectiveness of basiliximab against SRR as rescue therapy in pediatric LT patients with ALF. Forty pediatric ALF patients underwent LT between November 2005 and July 2013. Among them, seven patients suffering from SRR were enrolled in this study. The median age at LT was 10 months (6-12 months). SRR was defined as the occurrence of refractory rejection after more than two courses of steroid pulse therapy. Basiliximab was administered to all patients. The withdrawal of steroids without deterioration of the liver function was achieved in six patients treated with basiliximab therapy without patient mortality, although one patient developed graft loss and required retransplantation for veno-occlusive disease. The pathological examinations of liver biopsies in the patients suffering from SRR revealed severe centrilobular injuries, particularly fibrosis within one month after LT. We demonstrated the effectiveness and safety of rescue therapy consisting of basiliximab for SRR in pediatric LT recipients with ALF.

Abstract
The rapid development of new diagnostic tests and improved therapy, especially the success of liver transplantation, has changed the outcome for children with liver disease, many of whom survive into adolescence without liver transplantation. The indications for transplantation in adolescence are similar to pediatric indications and reflect the medical advances made in this specialty that allow later transplantation. These young people need a different approach to management that involves consideration of their physical and psychological stage of development. A focused approach to their eventual transition to adult care is essential for long-term survival and quality of life.

Abstract
OBJECTIVES Living-related liver transplantation (LRLT) was developed to increase the donor pool of size-matched organs for children. In the UK only one centre performed LRLT between 1993 and 2008. This study reports the clinical and histological outcomes following adult-to-paediatric LRLT at our centre. METHODS Forty-six LRLTs were reviewed. Recipients had a mean age, weight and PELD score of 2.4years (range 0.5-11years), 11.0kg (3.7-32.3kg) and 11.7 (-20.3 to 49.1) respectively. The incidence of post-transplant paediatric morbidity, abnormal liver function tests and histological abnormalities was reviewed. RESULTS Patient and graft survival rates were 97.8%, 95.1% and 95.1%, and 97.8%, 92.1% and 71.7% at 1, 5 and 10years post-transplant respectively. Three children were re-transplanted at 44, 100 and 119months post-transplant. Nine children developed neuropsychological problems, 6 experienced educational difficulties, 5 developed post-transplant lymphoproliferative disorder and 5 suffered height or weight growth<2 centile. Normal LFTs were found in 41.7%, 50%, 68% and 64.7% of children at median follow-up of 6, 13, 61 and 85months respectively. Liver histology showed hepatitis, acute rejection, non-specific changes, biliary pathology, vascular pathology and chronic rejection in 32.9%, 29.5%, 13.4%, 10.1%, 6% and 2% of biopsies respectively. CONCLUSIONS The prevalence of paediatric morbidity and histological abnormalities emphasize the need for specialist and long-term follow-up following LRLT in children.

Abstract
Racial and socioeconomic disparities exist in liver transplantation (LT) outcomes among adults, but little research exists for pediatric LT populations. We examined racial differences in graft survival and mortality within a retrospective cohort of pediatric and young adult LT recipients at a large children's transplant center in the Southeast between 1998 and 2011. The association between race/ethnicity and rates of graft failure and mortality was examined with Cox proportional hazards models that were adjusted for demographic and clinical factors as well as individual-level and census tract-level socioeconomic status (SES). Among the 208 LT recipients, 51.0% were white, 34.6% were black, and 14.4% were other race/ethnicity. Graft survival and patient survival were higher for whites versus minorities 1, 3, 5, and 10 years after transplantation. The 10-year graft survival rates were 84% [95% confidence interval (CI) = 76%-91%] for white patients, 60% (95% CI = 46%-74%) for black patients, and 49% (95% CI = 23%-77%) for other race/ethnicity patients. The 10-year patient survival rates were 92% (95% CI = 84%-96%), 65% (95% CI = 52%-79%), and 76% (95% CI = 54%-97%) for the white, black, and other race/ethnicity groups, respectively. In analyses adjusted for demographic, clinical, and socioeconomic characteristics, the rates of graft failure [black: hazard ratio (HR) = 2.59, 95% CI = 1.29-5.45; other: HR = 3.01, 95% CI = 1.23-7.35] and mortality (black: HR = 4.24, 95% CI = 1.54-11.69; other: HR = 3.09, 95% CI = 0.78-12.19) were higher for minority groups versus whites. In conclusion, at a large pediatric transplant center in the Southeastern United States, racial/ethnic disparities exist in pediatric and young adult LT outcomes that are not fully explained by measured SES and clinical factors.

Abstract
The success of paediatric liver transplantation is attributed to improved surgical techniques and the advent of calcineurin inhibitor-based immunosuppression. Acute rejection (AR) rarely results in graft loss with calcineurin inhibitor immunosuppressive regimens, and the advent of newer agents like interleukin (IL)-2 receptor antibodies. The latter have the benefit of reducing the incidence of AR further and may be of use in patients who are susceptible to recurrent AR, were retransplanted for graft rejection or are in a steroid-sparing regimen. A total of 60 % of all paediatric liver transplants result in AR; however, there is a 75 % response rate to initial steroid therapy. Steroid therapy remains the mainstay of initial AR management, coupled with an increase in baseline immunosuppression. Steroid-resistant rejection (SRR), previously an immediate indication for potent anti-lymphocyte preparations, is now effectively treated with chimeric or humanised IL-2 receptor monoclonal antibodies. Recurrent AR can be treated by adding adjuvant immunosuppressive agents such as mycophenolate mofetil (MMF) or sirolimus. Studies have also demonstrated the efficacy of MMF as rescue therapy for SRR. Anti-lymphocyte preparations such as anti-thymocyte globulin (ATG) and OKT3 are rarely used in SRR but may be of use as rescue therapy for severe SRR. The challenges of the management of AR remain in the management of recurrent AR and SRR. We discuss the pathogenesis, diagnosis and management of AR, including prevention, and specific management of AR and SRR based on current evidence and our own experience at the King's College Paediatric Liver, Gastroenterology and Nutrition Centre in London.

Abstract
This prospective inception cohort study determines kindergarten-entry neurocognitive abilities and explores their predictors following liver transplantation at age <3 yr. Of 52 children transplanted (1999-2008), 33 (89.2%) of 37 eligible survivors had psychological assessment at age 54.7 (8.4) months: 21 with biliary atresia, seven chronic cholestasis, and five acute liver failure. Neurocognitive scores (mean [s.d.], 100 [15]) as tested by a pediatric-experienced psychologist did not differ in relation to age group at transplant (≤12 months and >12 months): FSIQ, 93.9 (17.1); verbal (VIQ), 95.3 (16.5); performance (PIQ), 94.3 (18.1); and VMI, 90.5 (15.9), with >70% having scores ≥85, average or above. Adverse predictors from the pretransplant, transplant, and post-transplant (30 days) periods using univariate linear regressions for FSIQ were post-transplant use of inotropes, p = 0.029; longer transplant warm ischemia time, p = 0.035; and post-transplant highest serum creatinine, (p = 0.04). For PIQ, they were pretransplant encephalopathy, p = 0.027; post-transplant highest serum creatinine, p = 0.034; and post-transplant inotrope use, p = 0.037. For VMI, they were number of post-transplant infections, p = 0.019; post-transplant highest serum creatinine, p = 0.025; and lower family socioeconomic index, p = 0.039. Changes in care addressing modifiable predictors, including reducing acute post-transplant illness, pretransplant encephalopathy, transplant warm ischemia times, and preserving renal function, may improve neurocognitive outcomes.

Abstract
Pediatric liver transplantation (LT) is one of the most successful solid organ transplants with long-term survival more than 80%. Many aspects have contributed to improve survival, especially advancements in pre-, peri- and post-transplant management. The development of new surgical techniques, such as split-LT and the introduction of living related LT, has extended LT to small infants. Progress in the last 30 years has also been characterized by the introduction of calcineurin inhibitors. One problem remains the lack of donors. Donation after cardiac death offers a new possibility to increase the pool of potential donors. In children with acute liver failure, increasing interest has centered on the possibility of providing temporary liver support based on extracorporeal devices or hepatocyte transplantation. Similarly, hepatocyte transplantation offers new perspective in children with metabolic failure. As long-term survival increases, attention has now focused on the quality of life achieved by children undergoing LT.

Abstract
BACKGROUND Liver transplantation is considered as the standard treatment for both children and adults with end-stage liver diseases. Using this method, children who have no chance for life can live a much longer life .Shiraz Transplant Center is the major pediatric liver transplant center in Iran. Therefore, determining patients' survival and its effective factors can help clinical programming for increasing such patients' survival after liver transplantation. OBJECTIVES The present study aimed to investigate the survival of patients below-18-years-old undergoing liver transplantation and the factors affecting their survival. PATIENTS AND METHODS The present historical cohort study was conducted on 392 patients below-18-year-sold who had undergone liver transplantation for the first time in the Namazi hospital liver transplant center, Shiraz, Iran between 2000 and 2011. In this study, 1-, 3-, 5-, and 10-year survival of the patients was assessed using Kaplan-Meier and life table methods. The effect of factors related to the recipients, donors, and the transplantation process on the patients' survival was also investigated. RESULTS According to the results, 1, 3, 5 and 10-year survival of patients was 73%, 67%, 66%, and 66%, respectively. Besides, 1 ,3, 5, and 10-year survival of the patients who survived 1 and 3 months after the transplantation was 84%, 78%, 77%, and 77% and 89%, 82%, 81%, and 81%, respectively. In the univariate analysis, age, patients' weight at transplantation, initial diagnosis, PELD/MELD score, existence of post-transplant complications, and year of transplantation were found to be effective factors on the patients' survival. In the multivariate analysis, only the type of graft, PELD/MELD score, and existence of post-transplant complications were the prognostic variables. CONCLUSIONS In this study, the patients' survival rate was 73%, which is quite low compared to the survival rate reported in other studies. Although we only have a 12-year experience with pediatric liver transplantation, the survival rate has increased in our center through the recent years (2008-2011). However, the survival rate of the patients who had survived 3 months after the transplantation was 89% which is comparable to other studies. Overall, cholestatic diseases (biliary atresia was the most prevalent), type of transplantation (split), PELD/MELD score > 20, and existence of post-transplant complications increased the risk of death after the transplantation.
