Outcomes in Adult Liver Transplant Recipients Using Pediatric Deceased Donor Liver Grafts. Transplant Direct 2022; 8:e1315. [PMID: 35415214 PMCID: PMC8989770 DOI: 10.1097/txd.0000000000001315] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/14/2021] [Revised: 02/04/2022] [Accepted: 02/17/2022] [Indexed: 11/27/2022] Open
Abstract
Background. The use of pediatric grafts for liver transplantation (LT) into adult recipients is rare, and reported outcomes are conflicting. The aim of this study is to evaluate the outcomes in adult recipients following LT with grafts from deceased pediatric donors. Methods. A retrospective study identifying adult LT between 2010 and 2020 using pediatric deceased donor liver grafts was conducted. Adults undergoing LT with deceased donor pediatric grafts (age ≤ 12) were identified and matched 1:2 with adults receiving adult grafts (age ≥ 18) based on recipient age (±10 y), model for end-stage liver disease (MELD) score at transplant (±5 points) and etiology of liver disease. To assess real liver size differences between the pediatric-donor and adult-donor groups, patients receiving a graft from a donor between 13 and 17 y were excluded from the main analysis and studied independently. Outcomes between the groups were compared. Complication rates were identified and graded using Clavien–Dindo classification. Graft and patient survival were assessed by Kaplan–Meier curves. Results. Twelve adult LT recipients with whole liver grafts from deceased pediatric donors were matched with 24 adult recipients of adult donors. Recipient age and MELD score were similar between groups. Recipients of pediatric grafts were more likely to be female (66.7% versus 16.7%, P = 0.007) and leaner (body mass index = 24.4 versus 29.9, P = 0.013). Alcohol-related cirrhosis was the most prevalent liver disease etiology in both groups (P = 0.96). There was no significant difference in length of stay, readmissions, early complications, or major complications between groups. Vascular and biliary complication rates were similar. Actuarial graft and patient survival at 1, 3, and 5 y were 100/100/100 versus 96/96/96 (P = 0.48). Conclusions. Excellent patient and graft survival is achievable with LT using young pediatric deceased donor grafts in smaller adult recipients. Outcomes are comparable with recipients of age and MELD-matched adult donors. Careful donor MELD-score recipient matching and close monitoring for potential biliary and vascular complications are crucial to achieve acceptable outcomes.

Outcome of the use of paediatric donor livers in adult recipients: A single Chinese centre experience. Clin Res Hepatol Gastroenterol 2019; 43:148-154. [PMID: 30318357 DOI: 10.1016/j.clinre.2018.08.018] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/30/2017] [Revised: 08/22/2018] [Accepted: 08/30/2018] [Indexed: 02/04/2023]
Abstract
BACKGROUND Paediatric liver allografts sometimes are allocated to adult recipients when there are no suitable paediatric recipients on the waiting list. However, debate exits regarding the reported outcomes of liver transplants using such small grafts. METHODS Records from adult patients undergoing liver transplantation between February 2010 and January 2016 who received whole grafts from paediatric (≤ 13 years) donors or ideal deceased adult (18-35 years) donors were reviewed. Patient and graft survival, post-transplant liver function, and complications between the two groups were compared. RESULTS The baseline characteristics were comparable, except that the paediatric donor allografts had smaller size. The 3-month, 1-year, and 3-year rates of patient survival were 91.3%, 85.2%, and 85.2% in the paediatric donor group and 93.4%, 88.9%, and 85.0% in the adult donor group (P = 0.947), respectively. One patient receiving a paediatric allograft developed small-for-size liver syndrome post-transplantation. There was no difference in primary non-function, early allograft dysfunction, biliary complications, vascular complications, or infection between the two groups. CONCLUSION Our study indicates that using paediatric donor livers in well-selected adult recipients is a safe procedure, considering there was no suitable paediatric recipient. However, the risk of portal hyperperfusion should be considered in clinical cases such as size-mismatched transplants.

Abstract
OBJECTIVES This study aimed to investigate the outcomes of adult liver transplant procedures using grafts from pediatric donors after circulatory death. MATERIALS AND METHODS We retrospectively analyzed the data of 19 pediatric-to-adult liver transplant procedures from July 2013 to May 2016 in our hospital. Nineteen adult liver transplant procedures were performed using livers from pediatric donors after circulatory death. RESULTS We performed 18 orthotopic and 1 piggyback liver transplant procedure. The median graft-to-recipient weight ratio was 1.26% (range, 0.86% to 2.46%). The median warm and cold ischemia times were 11 minutes (range, 8-20 min) and 638 minutes (range, 200-843 min), respectively. Complications after the operation included postoperative pulmonary infection (8 patients), fungal infection (1 patient), cytomegalovirus infection (1 patient), hepatic artery thrombosis and biliary stricture (1 patient), portal vein stenosis (1 patient), and graft failure (2 patients). For patients with graft failure, 1 patient received retransplant and 1 died. The patients were followed for 22.44 months (range, 9.63-44.07 mo) after transplant and showed normal liver function and good health. The 3-year survival rates of grafts and patients were 89.47% and 94.74%, respectively. CONCLUSIONS Appropriate evaluation of donors and recipients and accurate intraoperative and postoperative treatment can ensure successful application of livers from pediatric donors after circulatory death in adult recipients.

Abstract
BACKGROUND The impact of using liver allografts from donors who are younger than 14 years at the time of donation after cardiac death (DCD) liver transplantation in terms of early allograft dysfunction (EAD) and graft survival is undefined. To determine if adults undergoing DCD liver transplantation who receive a graft from a donor age younger than or equal to 13 years have similar outcomes to recipients of organs from older than 18-year-old donors. METHODS Records from adult patients undergoing DCD liver transplantation between March 2012 and December 2015 who received whole grafts from donors after cardiac death were reviewed. Patients with donors younger than or equal to 13 years (group 1) and older than 18 years (group 2) were compared for EAD rates, hepatic artery thrombosis (HAT), and graft survival. RESULTS Records of 60 DCD liver transplantation patients were analyzed. The 90-day and 1-year graft survival rate of both groups was 90% versus 96% (P = .427) and 80% versus 84% (P = .668), respectively. The EAD rates of groups 1 and 2 were 30% versus 34% (P = .806). The incidence of HAT was 20% in group 1 compared with 12% in group 2 (P = .610). Also, 0.7% < graft to recipient weight ratio (GRWR) <0.8% was also usable for pediatric donor to adult recipients. CONCLUSIONS Whole liver grafts from donors younger than or equal to 13 years can potentially be used in selected size-matched (GRWR >0.7%) DCD adult recipients.

Abstract
Extended-criteria donors (ECDs) have an impact on early allograft dysfunction (EAD), biliary complications, relapse of hepatitis C virus (HCV), and survivals. Early allograft dysfunction was frequently seen in grafts with moderate and severe steatosis. Donors after cardiac death (DCD) have been associated with higher rates of graft failure and biliary complications compared to donors after brain death. Extended warm ischemia, reperfusion injury and endothelial activation trigger a cascade, leading to microvascular thrombosis, resulting in biliary necrosis, cholangitis, and graft failure. The risk of HCV recurrence increased by donor age, and associated with using moderately and severely steatotic grafts. With the administration of protease inhibitors sustained virological response was achieved in majority of the patients. Donor risk index and EC donor scores (DS) are reported to be useful, to assess the outcome. The 1-year survival rates were 87% and 40% respectively, for donors with a DS of 0 and 3. Graft survival was excellent up to a DS of 2, however a DS >2 should be avoided in higher-risk recipients. The 1, 3 and 5-year survival of DCD recipients was comparable to optimal donors. However ECDs had minor survival means of 85%, 78.6%, and 72.3%. The graft survival of split liver transplantation (SLT) was comparable to that of whole liver orthotopic liver transplantation. SLT was not regarded as an ECD factor in the MELD era any more. Full-right-full-left split liver transplantation has a significant advantage to extend the high quality donor pool. Hypothermic oxygenated machine perfusion can be applied clinically in DCD liver grafts. Feasibility and safety were confirmed. Reperfusion injury was also rare in machine perfused DCD livers.

Abstract
In LT, the common policy is to allocate pediatric liver grafts to pediatric recipients. Pediatric organs are also offered to adults if there is no pediatric recipient. However, they are rarely accepted for adult recipients. So far, there is no information available reporting outcome of LT in adult recipients using pediatric livers from donors ≤ 6 yr. In this study, we included nine adult recipients (seven females and two males) who received grafts from children ≤ 6 yr from January 2008 to December 2013. We evaluated the graft quality, the GBWR and analyzed the recipients' perioperative course. Laboratory samples and graft perfusion were analyzed. Nine adults with a median age of 49 yr (range: 25-65) and a median weight of 60 kg (range: 48-64) underwent LT with a pediatric donor graft. Median donor age was five yr (range: 3-6). Median GBWR was 1.02 (range: 0.86-1.45). After a median follow-up of 3.9 yr (range: 11 months-6.6 yr), patient survival was 100%; graft survival was 89%. One patient needed re-transplantation on the second postoperative day due to PNF. Eight recipients were discharged from the ICU after 2-9 days with a regular graft function. Doppler scans revealed regular flow patterns at any time. Only if denied for pediatric recipients, the use of pediatric livers from donors ≤ 6 yr for adult recipients is a considerable option.

Abstract
Nowadays, most paediatric liver transplant recipients receive a split or other technical variant graft from adult deceased or live donors, because of a lack of available age- and size matched paediatric donors. Few data are available, especially for liver grafts obtained from very young children (<6 years). We analysed all paediatric liver transplantations between 1989 and 2009. Recipients were divided into five groups (1-5) depending on donor age (<1, ≥1 to <6, ≥6 to <16, ≥16 to <45, ≥45 years). Overall, 413 paediatric liver transplantations from deceased donors were performed; 1- and 5-year graft survival rates were 75%, 80%, 78%, 81%, 74% and 75%, 64%, 70%, 67%, 46%, and 1- and 5-year patient survival rates were 88%, 91%, 90%, 89%, 78% and 88%, 84%, 84%, 83%, 63% for groups 1-5, respectively, without significant difference. Eight children received organs from donors younger than 1 year and 45 children received organs from donors between 1 and 6 years of age. Overall, vascular complications occurred in 13.2% of patients receiving organs from donors younger than 6 years. Analysis of our data revealed that the usage of liver grafts from donors younger than 6 years is a safe procedure. The outcome was comparable with grafts from older donors with excellent graft and patient survival, even for donors younger than 1 year.
