Abstract
BACKGROUND Kidney transplantation (KTx) from small donors is associated with inferior graft survival in registry studies, whereas single-center studies show favorable results. METHODS We compared 175 pediatric KTx from small donors ≤20 kg (SDKTx) with 170 age-matched recipients from adult donors (ADKTx) from 20 centers within the Cooperative European Paediatric Renal Transplant Initiative registry. Graft survival and estimated glomerular filtration rate (eGFR) were analyzed by Cox regression and mixed models. Detailed data on surgical and medical management were tested for association with graft survival. RESULTS One-year graft survival was lower after SDKTx compared with ADKTx (90.9% versus 96.5%; odds ratio of graft loss, 2.92; 95% confidence interval [CI], 1.10-7.80; P = 0.032), but 5-y graft survival was comparable (90.9% versus 92.7%; adjusted hazard ratio of graft loss 1.9; 95% CI, 0.85-4.25; P = 0.119). SDKTx recipients had an annual eGFR increase of 8.7 ± 6.2 mL/min/1.73 m² compared with a decrease of 6.9 ± 5.7 mL/min/1.73 m² in ADKTx recipients resulting in a superior 5-y eGFR (80.5 ± 25.5 in SDKTx versus 65.7 ± 23.1 mL/min/1.73 m² in ADKTx; P = 0.008). At 3 y posttransplant, eGFR after single SDKTx was lower than after en bloc SDKTx (86.6 ± 20.4 versus 104.6 ± 35.9; P = 0.043) but superior to ADKTx (68.1 ± 23.9 mL/min/1.73 m²). Single-kidney SDKTx recipients had a lower rate of hypertension at 3 y than ADKTx recipients (40.0% versus 64.7%; P = 0.008). CONCLUSIONS Compared with ADKTx, 5-y graft function is superior in SDKTx and graft survival is similar, even when performed as single KTx. Utilizing small donor organs, preferably as single kidneys in experienced centers, is a viable option to increase the donor pool for pediatric recipients.

Ogura T, Shiraishi C, Tamura Y, Urawa A. Comparison of Adverse Events Following Immunosuppressant Administration for Pediatric Patients With Renal Transplants Categorized by Two-Year Age Increments Using the U.S. Food and Drug Administration Adverse Event Reporting System. Cureus 2024; 16:e65300. [PMID: 39184624 PMCID: PMC11343616 DOI: 10.7759/cureus.65300] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 07/21/2024] [Indexed: 08/27/2024] Open
Abstract
Background Immunosuppressants are frequently administered to prevent transplant rejection in patients with renal transplants but cause various adverse events. The incidence of each adverse event may differ between pediatric and adult patients with renal transplants. Because the development of organs and bodies in pediatric patients varies greatly annually, the incidence of each adverse event following immunosuppressant administration may vary by age. Consequently, the age-specific incidence of each adverse event in pediatric patients represents invaluable information for clinical settings. To clarify trends in the occurrence of adverse events by age, a large sample size for each age is required. However, it is difficult to conduct clinical trials in pediatric patients with renal transplants with a large sample size for each age. One method to address this difficulty is to use a database. Objectives This study aimed to investigate the trends in the occurrence of each adverse event following immunosuppressant administration in pediatric patients with renal transplants, categorized by two-year age increments. Methods We extracted data on pediatric patients aged 0-17 years who received immunosuppressants after renal transplant between January 2004 and March 2024 from the U.S. Food and Drug Administration Adverse Event Reporting System. Because adverse events were greatly affected by age, the patients were divided into groups by two-year age increments. We analyzed the relationship between the groups and the reporting proportion of each adverse event by using the reporting regression coefficient (RRC) from univariate regression analysis and the adjusted RRC (aRRC), which controlled for differences in patient background. Results Renal tubular necrosis, renal impairment, chronic allograft nephropathy, and headache were the adverse events that required more attention with increasing age because RRC and aRRC were significantly > 0. By contrast, Epstein-Barr virus infection was the adverse event that required attention, especially in younger pediatric patients, because RRC and aRRC were significantly < 0. Additionally, there were various trends among other adverse events, including those that required careful monitoring across all ages 0-17 years. Conclusions This study demonstrated that the types of adverse events requiring attention in pediatric patients with renal transplants differ by age. These findings can help enhance treatment and care in pediatric clinical settings.

Long-term outcome of pediatric renal transplantation with donors younger than 6 years. Pediatr Transplant 2024; 28:e14761.

Abstract
BACKGROUND Renal transplantation is currently the best treatment option for patients with end-stage renal disease. However, the use of kidneys from donors under 6 years of age as a possibility to increase the organ pool in pediatric recipients remains a controversial matter. We aimed to investigate whether donor age is associated to the long-term functionality of the renal graft. Likewise, we analyzed the adaptation of the graft to the ascending functional requirements in the pediatric patient. METHODS Retrospective study of the results obtained in pediatric recipients transplanted with grafts from donors between 3 and 6 years of age, comparing them with those of grafts from donors older than 6 years. Among the variables compared are cumulative graft survival, renal size, need for antiproteinuric therapy, GFR, incidence of rejection, pyelonephritis, renal failure and surgical or tumor complications. RESULTS A total of 43 transplants were performed with donors aged 3-6 years, and 42 transplants with donors older than 6 years. Cumulative graft survival at 5 years was 81% for the younger donor group compared to 98% for the older donor group (p < .05). At 8 years, cumulative graft survival for donors <6 years was 74%. As for the mean estimated graft survival, it was 11.52 years for the younger donor group and 14.51 years for older donors. During follow-up, the younger donor group presented greater renal enlargement and need for antiproteinuric therapy. The older donors group had a higher GFR during the first year of follow-up, which then equalized in both groups. There were no statistically significant differences in the incidence of acute or chronic rejection, acute pyelonephritis, acute renal failure or surgical or tumor complications. CONCLUSIONS Renal transplants of grafts equal to or less than 6 years old have good short-term and acceptable long-term results in pediatric patients.

Abstract
BACKGROUND Kidney transplantation (KT) is the best therapy in children with end-stage renal disease (ESRD), however, improving long-term graft survival remains challenging. The aim of this study was to determine graft survival and potential risk factors in pediatric patients who undergo deceased donor KT with a steroid-based regimen. METHODS The medical records of children who underwent their first deceased donor KT in Srinagarind Hospital (Khon Kaen, Thailand) between 2001 and 2020 were reviewed. RESULTS Seventy-two patients were studied. Male adolescents were the predominant recipients and the majority of donors were young adult males. Non-glomerular disease, particularly hypoplastic/dysplastic kidney disease, was the major cause of ESRD (48.61%). The mean cold ischemic time (CIT) was 18.29 ± 5.29 h. Most of the recipients had more than 4 human leukocyte antigen (HLA) mismatched loci with positive HLA-DR mismatch (52.78%). Induction therapy was administered in 76.74% of recipients. Tacrolimus plus mycophenolate sodium and prednisolone was the most common immunosuppressive maintenance regimen (69.44%). Graft failure occurred in 18 patients, mostly due to graft rejection (50%). Graft survival at 1, 3, and 5 years after KT were 94.40%, 86.25%, and 74.92%, respectively. The only significant risk factor of graft failure in this study was delayed graft function (DGF) (adjusted HR = 3.55; 95%CI: 1.14, 11.12; p = .029). Patient survival at 1, 3, and 5 years was 100%, 98.48%, and 96.19%, respectively. CONCLUSION The short-term outcomes of pediatric KT from deceased donors were satisfactory; however, prevention of DGF would result in better outcomes.

Abstract
BACKGROUND A new Kidney Allocation System (KAS) was implemented in the United States in 2014 with the goal of improving equity and utility. METHODS In this study, we compare outcomes for kidney-alone candidates less than 18 years of age, at the time of listing, in the 5 years prior to and following policy implementation using Organ Procurement and Transplantation Network data. RESULTS While the pediatric deceased donor transplant rate increased under KAS, this increase was due solely to improved access for children aged 11-17 years; there was an 18.9% decrease in the deceased donor transplant rate among children 0-5 years old, from 117.94 to 95.8 transplants per 100 person-years (p = .001). The cumulative incidence of deceased donor transplantation by 1 year after listing decreased from 39.3% in the pre-KAS era to 35.5% in the post-KAS era (p = .004), a decline that was driven entirely by longer wait times for children 0-5 years old (p = .017). Candidates with a calculated panel reactive antibody of 98%-100% experienced a significant increase in transplant rate, but there was no change in transplant rate for Black or Hispanic candidates. CONCLUSION Overall, KAS increased transplantation access for teenaged and highly sensitized candidates but resulted in decreased access for the youngest children with no improvement in racial/ethnic equality.

Abstract
BACKGROUND Detection of donor-derived cell-free DNA (dd-cfDNA) reliably identifies allograft rejection in pediatric and adult kidney transplant (KT) recipients. Here, we evaluate the utility of dd-cfDNA for monitoring response to treatment among pediatric renal transplant recipients suffering graft rejection. METHODS 58 pediatric transplant recipients were enrolled between April 2018 and March 2020 and underwent initial dd-cfDNA testing to monitor for rejection. Allograft biopsy was performed for dd-cfDNA scores >1.0%. Patients with histologically proven rejection formed the study cohort and underwent appropriate treatment. Results of dd-cfDNA, serum creatinine (SCr), biopsy findings, and treatment outcomes were evaluated. Standard statistical analyses were applied. RESULTS Nineteen of 58 (31%) patients had dd-cfDNA score >1.0%, of which 18 (94.7%) had biopsy-proven rejection. Median dd-cfDNA value was 1.90% (interquartile range 1.43%-3.23%), and biopsy results showed 11 patients (61.1%) with antibody-mediated rejection (AMR), 2 patients (11.1%) with T-cell mediated rejection (TCMR), and 5 patients (27.7%) with mixed AMR/TCMR. SCr at time of biopsy was 1.28 ± 1.09 mg/dl. Following treatment, dd-cfDNA scores decreased for all types of rejection but still remained >1.0% in both AMR (1.50% [0.90%-3.10%]) and mixed (1.40% [0.95%-4.15%]) groups. Repeat dd-cfDNA values were <1.0% for patients with TCMR (0.20%-0.28%). SCr showed minimal change from pre-treatment levels regardless of rejection subtype. CONCLUSIONS Patients with TCMR may be reliably followed by dd-cfDNA; however, it remains unclear whether persistently elevated dd-cfDNA levels in AMR is a reflection of ongoing subclinical rejection or an inherent limitation of the assay's utility.

Abstract
Worldwide, over 1,300 pediatric kidney transplantations are performed every year. Since the first transplantation in 1959, healthcare has evolved dramatically. Pre-emptive transplantations with grafts from living donors have become more common. Despite a subsequent improvement in graft survival, there are still challenges to face. This study attempts to summarize how our understanding of pediatric kidney transplantation has developed and improved since its beginnings, whilst also highlighting those areas where future research should concentrate in order to help resolve as yet unanswered questions. Existing literature was compared to our own data of 411 single-center pediatric kidney transplantations between 1968 and 2020, in order to find discrepancies and allow identification of future challenges. Important issues for future care are innovations in immunosuppressive medication, improving medication adherence, careful donor selection with regard to characteristics of both donor and recipient, improvement of surgical techniques and increased attention for lower urinary tract dysfunction and voiding behavior in all patients.

Abstract
Background Alemtuzumab is a T cell depleting antibody agent used as induction immunosuppressant therapy in solid organ transplant recipients. In addition, it is being increasingly used to treat severe or glucocorticoid-resistant graft rejection. Despite the effectiveness of the treatment, severe adverse events have been reported related to alemtuzumab administration. We present a similar event illustrating the severity of this adverse drug reaction (ADR) and we highlight the structure causality assessment provides in approaching such a case. Case presentation We report a case of life-threatening respiratory failure after alemtuzumab administration in a 17 year old paediatric kidney transplant recipient. He developed near fatal severe respiratory and circulatory failure based on acute respiratory distress syndrome (ARDS) with diffuse alveolar oedema and haemoptysis hours after his second alemtuzumab administration. As it was questionable whether alemtuzumab could be regarded as the origin of his reaction and in order to assess the causality of this reaction as well as to structure clinical reasoning, we applied a widely used ADR probability scale to systematically review our case. Discussion and conclusions Our case shows a severe ADR after alemtuzumab administration. It illustrates the importance of proper causality assessment, the structure it provides and the benefit of a clinical pharmacology consultation when a severe reaction is suspected to be an ADR. By taking our case as an example, we demonstrate the added value of structured causality assessment to clinical reasoning and in generating differential diagnoses.

Abstract
Kidney transplantation increases life expectancy and improves quality of life for children with end-stage kidney disease, yet sequelae of transplantation and treatment make it difficult for transplant recipients to enjoy health and quality of life similar to their healthy peers. The NAPRTCS network was among the first to use multicenter data to inform improvements in care and outcomes for children with a kidney transplant through observational research. Now, with new technologies and unprecedented access to data, it is possible to create learning health systems as envisioned by the US National Academy of Sciences to seamlessly integrate research and continuous improvement of clinical care. In this review, we present two pre-eminent North American networks focused on using multicenter data to drive improved care and outcomes for children with a kidney transplant. Whereas, for the past 30 years NAPRTCS has focused on discovery of best practices through observational research and clinical trials, the Improving Renal Outcomes Collaborative, established in 2016, engages patients, families, clinicians, and researchers in redesigning the healthcare delivery system to enable practice change and continuous improvement of health outcomes. We discuss the history and past contributions of these networks, as well as current activities, barriers, and potential future solutions to more fully realize the vision of a true learning health system for pediatric kidney transplant recipients.

Abstract
Background Access to kidney transplantation by uremic children is very limited due to the lack of donors in many countries. We sought to explore small pediatric kidney donors as a strategy to provide transplant opportunities for uremic children. Methods A total of 56 cases of single pediatric kidney transplantation and 26 cases of en bloc kidney transplantation from pediatric donors with body weight (BW) less than 10 kg were performed in two transplant centers in China and the transplant outcomes were retrospectively analyzed. Results The 1-year and 2-year death-censored graft survival in the en bloc kidney transplantation (KTx) group was inferior to that in the single KTx group. Subgroup analysis of the single KTx group found that the 1-year and 2-year death-censored graft survival in the group where the donor BW was between 5 and 10 kg was 97.7 and 90.0%, respectively. However, graft survival was significantly decreased when donor BW was ≤5 kg (p < 0.01), mainly because of the higher rate of thrombosis (p = 0.035). In the single KTx group, the graft length was increased from 6.7 cm at day 7 to 10.5 cm at 36 months posttransplant. The estimated glomerular filtration rate increased up to 24 months posttransplant. Delayed graft function and urethral complications were more common in the group with BW was ≤5 kg. Conclusions Our study suggests that single kidney transplantation from donors weighing over 5 kg to pediatric recipients is a feasible option for children with poor access to transplantation.

Pediatr Transplant 2019; 23:e13597. [PMID: 31657095 DOI: 10.1111/petr.13597] [Citation(s) in RCA: 71] [Impact Index Per Article: 14.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/01/2019] [Revised: 08/25/2019] [Accepted: 09/16/2019] [Indexed: 11/28/2022]
Abstract
The NAPRTCS has collected clinical information on children undergoing renal transplantation since 1987 and now includes information on 12 920 renal transplants in 11 870 patients. Since the first data analysis in 1989, NAPRTCS reports have documented marked improvements in patient and allograft outcomes after pediatric renal transplantation in addition to identifying factors associated with both favorable and poor outcomes. The registry has served to document and influence practice patterns, clinical outcomes, and changing trends in renal transplantation and also provides historical perspective. This report highlights current practices in an era of major changes in DD kidney allocation and continuing steroid minimization. This report presents outcomes of the patients in the NAPRTCS transplant registry up to end of 2017. In particular, an increase in the cumulative incidence of late first AR has occurred in the most recent cohort, while all prior cohorts had a lower cumulative incidence of late first AR.

Abstract
BACKGROUND To provide recommendations for the care of infants with stage 5 chronic kidney disease (CKD5). SETTING European Paediatric Dialysis Working Group. DATA SOURCES Literature on clinical studies involving infants with CKD5 (end stage renal failure) and consensus discussions within the group. RECOMMENDATIONS There has been an important change in attitudes towards offering RRT (renal replacement therapy) to both newborns and infants as data have accumulated on their improved survival and long-term outcomes. The management of this challenging group of patients differs in a number of ways from that of older children. The authors have summarised the basic recommendations for treating infants with CKD5 in order to support the multidisciplinary teams who endeavour on this difficult task.
