Abstract
BACKGROUND The benefits of normothermic regional perfusion (NRP) in posttransplant outcomes after controlled donation after the determination of death by circulatory criteria (cDCD) has been shown in different international adult experiences. However, there is no information on the use of NRP in pediatric cDCD donors. METHODS This is a multicenter, retrospective, observational cohort study describing the pediatric (<18 y) cDCD procedures performed in Spain, using either abdominal NRP or thoracoabdominal NRP and the outcomes of recipients of the obtained organs. RESULTS Thirteen pediatric cDCD donors (age range, 2-17 y) subject to abdominal NRP or thoracoabdominal NRP were included. A total of 46 grafts (24 kidneys, 11 livers, 8 lungs, 2 hearts, and 1 pancreas) were finally transplanted (3.5 grafts per donor). The mean functional warm ischemic time was 15 min (SD 6 min)' and the median duration of NRP was 87 min (interquartile range, 69-101 min). One-year noncensored for death kidney graft survival was 91.3%. The incidence of delayed graft function was 13%. One-year' noncensored-for-death liver graft survival was 90.9%. All lung and pancreas recipients had an excellent evolution. One heart recipient died due to a septic shock. CONCLUSIONS This is the largest experience of pediatric cDCD using NRP as graft preservation method. Although our study has several limitations, such as its retrospective nature and the small sample size, its reveals that NRP may increase the utilization of cDCD pediatric organs and offer optimal recipients' outcomes.

Abstract
The number of children being listed for transplant continues to be greater than the number of available organs. In fact, over the past decade, rates of liver and kidney transplants in pediatric transplantation are essentially unchanged (Am J Transplant. 2020;20:193 and Am J Transplant. 2020;20:20). The use of DCD donors offers a potential solution to organ scarcity; however, the use of DCD organs in pediatric transplantation remains a rare event. Pediatric transplants done using carefully chosen DCD donor organs have shown to have outcomes similar to those seen with the use of donation after brain death (DBD) donors. Herein, we review the literature to examine the utilization of DCD livers and kidneys, outcomes of these allografts, and assess if DCD organs are a viable method to increase organ availability in pediatric transplantation.

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 NMP provides a superior strategy for the assessment and preservation of marginal donor livers and has demonstrated increased utilization and enhances organ quality when used in adult liver transplantation. We aimed to evaluate the interest of incorporating the use of NMP in pediatric liver transplantation. METHODS An anonymous online survey was distributed to pediatric transplant surgeons and hepatologists across the United States. Respondent demographic information, attitudes toward NMP in pediatric liver transplantation, and barriers to utilization were examined. RESULTS Thirty-two providers (18 transplant surgeons and 14 hepatologists) completed the survey, yielding a response rate of 64%. Half (50%) of respondents indicated prior exposure to NMP. Overall, 96% of respondents believed there was benefit to using NMP in pediatric liver transplantation. DCD (68%) and post-cross-clamp (75%) grafts were the greatest opportunity for NMP use. A role in splitting livers ex vivo (71%) was also seen as a potential major opportunity. Cost was perceived as a barrier to implementation (36%), followed by institutional factors (32%). Cost tolerance was significantly greater in respondents residing in OPTN regions with greater than median wait times (63% vs. 11% in OPTN regions with greater vs. shorter wait times, p = .010). CONCLUSIONS There is significant interest within the pediatric liver transplant community for NMP to expand the donor pool. Interest appears particularly strong in regions where wait times for suitable pediatric donors are prolonged.

Abstract
The wait list for organ transplant exceeds the rate of organ donation, especially in children. The solid-organ transplant rate has remained stable over time, despite increased demand. Although donation after cardiac death has helped to expand the donor organ pool for the adult population, this option remains scarce for children in need of transplant. Because long-term graft survival is more important in the pediatric group than in adults, we should reconsider the common notion that donation after cardiac death is inferior to donation after brain death. Herein, we review the literature to extract and analyze data regarding donation after cardiac death for solid-organ transplant in children.

Abstract
Waiting list mortality together, with limited availability of organs, are one of the major challenges in liver transplantation (LT). Especially in the paediatric population, another limiting factor is the scarcity of transplantable liver grafts due to additional concerns regarding graft size matching. In adults, donation after circulatory death (DCD) liver grafts have been used to expand the donor pool with satisfactory results. Although several studies suggest that DCD livers could also be used in paediatric recipients with good outcomes, their utilisation in children is still limited to a small number of reports. Novel organ perfusion strategies could be used to improve organ quality and help to increase the number of DCD grafts utilised for children. With the current manuscript, we present the available literature of LT using DCD grafts in paediatric recipients, discussing current challenges with the use of these livers in children and how machine perfusion technologies could be of impact in the future.

Abstract
Although the utilization of donation after circulatory death donors (DCDs) for liver transplantation (LT) has increased steadily, much controversy remains, and no common acceptance criteria exist with regard to donor and recipient risk factors and prediction models. A consensus conference was organized by International Liver Transplantation Society on January 31, 2020, in Venice, Italy, to review the current clinical practice worldwide regarding DCD-LT and to develop internationally accepted guidelines. The format of the conference was based on the grade system. International experts in this field were allocated to 6 working groups and prepared evidence-based recommendations to answer-specific questions considering the currently available literature. Working group members and conference attendees served as jury to edit and confirm the final recommendations presented at the end of the conference by each working group separately. This report presents the final statements and recommendations provided by working group 2, covering the entire spectrum of donor and recipient risk factors and prediction models in DCD-LT.

Abstract
In pediatrics, an increasing need for transplantable organs exists. This study aimed to describe the epidemiology of pediatric deceased donors in the United States. This retrospective observational study utilized data from the Organ Procurement and Transplantation Network (OPTN) from 2000 to 2015. Patients were stratified based on method of organ donation. Demographic variables and mechanism of death were then compared. A total of 14,481 deceased pediatric organ donors, donation after brain death (DBD) and donation after circulatory death (DCD), were included in the study, of which 8% were DCD donors. A significant difference (p<0.001) existed between the two donor groups with respect to ethnicity and mechanism of death. The annual trend of DCD and DBD donors showed an inverse relationship. During the 15-year study period the number of DBD donors decreased from 985 to 785 per year while DCD donors increased from 15 to 146 per year. As well, overall organs transplanted per year decreased from 3,475 to 3,117 over the 15-year study period. Significant differences exist between pediatric DBD donors and DCD donors, specifically with respect to ethnicity and mechanism of death. The number of pediatric DBD donors is decreasing while the number of pediatric DCD is slowly rising, making it increasingly important to be able to characterize these donors to better identify eligible DCD donors to optimize organ utilization.

Abstract
Pediatric organ donation represents only a low proportion of overall organ donation in many parts of world, unable to match the needs for pediatric organ transplantation. Pediatric organ donation after circulatory determination of death (DCD) is increasingly explored in pediatric transplantation, as it increases the availability of organ grafts. A 6-year-old Caucasian boy with a history of arteriovenous malformation presented with a catastrophic intracranial bleed, resulting in severe brainstem dysfunction despite maximal medical and surgical measures. He did not fulfill the criteria for brain death, which must be met for pediatric organ donation in Singapore. Due to parental request, his organs were donated after withdrawal of life support and determination of death by circulatory criteria. Pediatric organ DCD poses many challenges in the pediatric population, especially in the absence of a local practice guideline. We present the first case of a pediatric organ DCD that has occurred in Singapore. Further work is needed, particularly in establishing a national policy for pediatric organ DCD and increasing overall awareness and acceptance toward pediatric organ donations.

Abstract
Despite increased numbers of donation after circulatory death (DCD) donors, pediatric DCD livers are underused. To investigate possible reasons for this discrepancy, we conducted a retrospective cohort study using 2 data sets from the Organ Procurement and Transplantation Network for all deceased liver donors and for all recipients of DCD liver transplants from March 8, 1993, to June 30, 2018. Pediatric (0-12 years) and adolescent (13-17 years) DCD donors were compared with those aged 18-40 years. We found that pediatric DCD allografts are recovered at a significantly lower rate than from 18-to-40-year-old donors (27.3% versus 56.3%; P < 0.001). However, once recovered, these organs are transplanted at a similar rate to those from the 18-to-40-year-old donor cohort (74.7% versus 74.2%). Significantly more pediatric DCD livers (odds ratio [OR], 3.75; confidence interval [CI], 3.14-4.47) were not recovered compared with adult organs, which were most commonly not recovered due to organ quality (10.2% versus 7.1%; P < 0.001). The 10-year relative risks (RRs) for graft failure and patient death were similar between pediatric and adult DCD donors, with adolescent DCD livers demonstrating improved outcomes. DCD livers transplanted into pediatric donors were protective against graft failure (RR, 0.46; 95% confidence interval [CI], 0.21-0.99) and patient death (RR, 0.16; 95% CI, 0.04-0.69). In conclusion, despite lower rates of recovery, pediatric DCD livers represent a viable organ source for certain adults and children.

Abstract
The utilization of donation after circulatory death (DCD) livers has been growing over the last decade. In large-volume centers, survival outcomes have improved and are comparable to outcomes with brain death donor (DBD) liver transplantation (LT). The relatively concentrated success with DCD LT demonstrated by high-volume transplant centers has rekindled international enthusiasm. The combination of increasing expertise in DCD LT and ongoing shortage in transplantable organs has promoted expansion of the DCD donor pool with regards to donor age, body mass index and donor warm ischemia time. In this review, we focused on the practice patterns in DCD liver graft utilization in the last decade, along with the possibilities for further expansion of DCD liver graft utilization and new technologies, such as machine perfusion.

Abstract
Despite the high number of children listed for kidney transplantation and shortage of deceased organ donors, there is reluctance to utilize DCD kidneys in pediatric recipients. We examined outcomes in pediatric kidney transplant patients who received a DCD kidney allograft. UNOS database was queried to examine outcomes in all pediatric kidney transplant recipients from 1994 to 2017. Pediatric status was defined as <18 years at the time of transplantation. Recipients were divided by DBD or DCD allograft status. Donor and recipient demographic data were examined. Patient and allograft survival was calculated, and Kaplan-Meier survival curves were generated. A P-value of <0.05 was considered to be significant. A total of 286 pediatric kidney transplant recipients received a DCD allograft. The donors in the DCD group were significantly younger than those in the DBD group (21.7 vs 23.3 years), with a higher KDPI (26.5% vs 22.9%). In the DCD group, the average age at transplant was younger (11.6 vs 12.9 years), with no difference in cold ischemia time or length of stay between the two groups. Rates of delayed graft function were higher in the DCD group, but despite this, there were no significant differences in allograft or patient survival between the groups. There is no difference in allograft survival in pediatric kidney transplant recipients who receive a DCD kidney allograft. DCD kidney allografts are suitable for transplantation in pediatric patients and can greatly expand the donor pool.

Abstract
BACKGROUND Strategies to expand numbers of deceased donor kidneys suitable for pediatric recipients are urgently needed to prevent long-term dialysis-associated morbidity and mortality. Donors designated as increased risk of disease transmission (IRD) are infrequently used in pediatric recipients. We examined outcomes of these kidneys in pediatric patients and the potential to increase the donor pool. METHODS The United Network for Organ Sharing (UNOS) database records presence of IRD in all deceased donors since 2004. All pediatric kidney transplant recipients from 2004 to 2017 were identified and stratified by IRD status, and outcomes were examined. RESULTS Four hundred seventy-three pediatric kidney transplant recipients received an IRD allograft. IRD donors had lower kidney donor profile index (KDPI); were more likely to be younger, male, and Caucasian; and were more likely to have used drugs. IRD kidneys were more likely to have been biopsied and placed on pulsatile perfusion. Other than an older recipient age, demographic data were not different between groups. Allograft and patient survivals were similar, as were rejection and delayed graft function rates. Compared with adult recipients and adult IRD recipients, pediatric recipients were more likely to have a younger donor, receive a kidney with a lower creatinine, and were less likely to have delayed graft function (p < 0.05). There were no recorded disease transmissions in IRD group. CONCLUSIONS Patient and allograft survivals are similar in IRD and non-IRD kidneys. High-quality IRD organs used in adults represent a large number of donors with excellent outcomes. IRD allografts have a potential to increase transplant volume and should be considered for pediatric patients.
