Tacrolimus IPV Group Membership Does Not Consistently Track With Electronically Monitored or Self-reported Adherence in Adolescent and Young Adult Kidney Transplant Recipients. Transplant Direct 2025; 11:e1806. [PMID: 40371052 PMCID: PMC12074067 DOI: 10.1097/txd.0000000000001806] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/20/2025] [Revised: 03/11/2025] [Accepted: 03/25/2025] [Indexed: 05/16/2025] Open
Abstract
Background High intrapatient variability (IPV) of tacrolimus trough concentrations (SD ≥ 2, coefficient of variation (CV%) ≥ 30) is associated with rejection and graft loss and may indicate nonadherence. However, the association between tacrolimus IPV and electronically monitored or self-reported adherence is unknown. Methods This secondary analysis of the TAKE-IT (Teen Adherence in Kidney Transplant Effectiveness of Intervention Trial) compared electronically monitored and self-reported adherence between participants with high and low tacrolimus IPV among 103 adolescent and young adult kidney transplant recipients (mean age = 15.18 y, 59% male, 60% White, 65% >1-y posttransplant). Results Electronically monitored daily taking and timing adherence were not significantly associated with tacrolimus IPV group in binomial generalized linear mixed effects models: Participants with tacrolimus SD ≥ 2 or CV% ≥ 30 were no less likely to take each daily dose than those below these cutoffs (SD < versus ≥ 2: odds ratio [OR]; 0.84, 95% confidence interval [CI], 0.48-1.47; P = 0.54 and CV% < versus ≥ 30: OR, 0.72; 95% CI, 0.43-1.21; P = 0.22). Participants with tacrolimus SD ≥ 2 or CV% ≥ 30 were no less likely to take each daily dose on time than those below these cutoffs (SD < versus ≥ 2: OR, 0.70; 95% CI, 0.40-1.23; P = 0.21 and CV% < versus ≥ 30: OR, 0.68; 95% CI, 0.40-1.16; P = 0.15). Electronically monitored averages of doses taken, doses taken early/late, and differences from expected dose time were associated with tacrolimus IPV (P < 0.05) but were poor classifiers of IPV group membership (area under the curve < 0.70). Self-reported adherence was not associated with tacrolimus IPV. Conclusions Tacrolimus IPV group membership does not consistently track with behavioral adherence measures. Relying on tacrolimus IPV group membership may misidentify nonadherence in adolescent and young adult kidney transplant recipients.

Abstract
BACKGROUND Today, most children with end-stage renal disease and after kidney transplantation reach adulthood, even with complex underlying diseases. As a result, nephrologists in internal medicine are increasingly encountering patients with clinical pictures that used to play only a minor role in the past. RESEARCH QUESTION The aim of this article is to provide an overview of the transition currently taking place in German nephrology and to offer perspectives for improving the process. MATERIALS AND METHODS Based on current literature and transition initiatives in German nephrology, the current situation of transition in Germany is analyzed and compared with the requirements of the AWMF ("Arbeitsgemeinschaft der Wissenschaftlichen Medizinischen Fachgesellschaften") S3 guideline "Health care transition from pediatric to adult care". RESULTS The transition from pediatric to internal nephrology marks a vulnerable phase for patients, in which problems in therapy cooperation occur with above-average frequency. Based on the AWMF S3 guideline, the transition in nephrology is defined as an interdisciplinary challenge based on the special features of pediatric-nephrology patients, barriers are identified and options for action are presented. CONCLUSION In Germany, different local transition models are practiced in nephrology, not all of which meet the requirements of the guideline. A harmonization of the procedure is necessary. However, this requires appropriate funding for transition.

Abstract
The post-transplant course of pediatric kidney transplant recipients is marked by a myriad of challenges, encompassing medical complications, recurrent hospitalizations, physical and dietary restrictions, and mental health concerns such as depression, anxiety, and post-traumatic stress disorder. Moreover, pediatric recipients are at risk of neurodevelopmental impairment, which may result in neurocognitive deficits and pose significant psychosocial obstacles. Addressing these multifaceted demands necessitates a multidisciplinary approach to pediatric kidney transplant care. However, the existing literature on the effective implementation of such a model remains scarce. This review examines the psychosocial and neurodevelopmental challenges faced by pediatric kidney transplant recipients and their families, discussing their impact on long-term transplant outcomes. Furthermore, it provides insights into risk assessment strategies and potential interventions within a multidisciplinary framework, aiming to enhance patient care and optimize post-transplant outcomes.

Suh H. Identifying Risk Factors for Graft Failure due to Chronic Rejection < 15 Years Post-Transplant in Pediatric Kidney Transplants Using Random Forest Machine-Learning Techniques. Pediatr Transplant 2025; 29:e70043. [PMID: 39981772 PMCID: PMC11843590 DOI: 10.1111/petr.70043] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/30/2023] [Revised: 12/20/2024] [Accepted: 01/24/2025] [Indexed: 02/22/2025]
Abstract
BACKGROUND Chronic rejection forms the leading cause of late graft loss in pediatric kidney transplant recipients. Despite improvement in short-term graft outcomes, chronic rejection impedes comparable progress in long-term graft outcomes. METHODS Data from the national Standard Transplant Analysis and Research (STAR) quarterly file from 1987 to 2023, provided by the Organ Procurement and Transplantation Network (OPTN), and machine-learning techniques were leveraged to determine novel risk factors for graft failure due to chronic rejection in pediatric kidney transplants. A predictive model was developed in conjunction, based on the performances of six classification models, including logistic regression, k-Nearest Neighbors, Support Vector Machine, Decision Tree, Artificial Neural Network, and Random Forest. RESULTS The 19 pre-transplant and at-transplant factors identified include those substantiated in literature, such as living donor type, cold ischemic time, human leukocyte antigen (HLA) matching, recipient age, and recipient race. Other factors include one-haplotype matched transplants, recipient age being < 5 years, and the proximities of the most and least recent serum crossmatch tests to transplantation. The latter may correlate with recipient sensitization and socioeconomic disparities, but further research must be done to validate this hypothesis. The Random Forest model was selected based on its performance metrics (AUC 0.81). CONCLUSIONS This case-control study identifies key factors for chronic rejection-caused graft failure 15 years post-transplant in pediatric kidney transplants and develops a Random Forest predictive model based on these factors. Continued investigation is needed to better understand the variables contributing to pediatric chronic kidney rejection.

Abstract
BACKGROUND Kidney transplantation (KT) in children and adolescents with severe motor and intellectual disabilities (SMID) has been a topic of controversy. A multicenter study in Japan showed that KT was not contraindicated for children with multiple handicaps, but no consensus has been reached on KT for patients with SMID. This study aimed to determine whether KT is a viable treatment option for children and adolescents with SMID. METHODS A single-center, retrospective study was conducted on children and adolescents with SMID who underwent KT. SMID was defined based on Oshima's classification. Clinical information was collected through a review of medical records. RESULTS Of 453 children and adolescents who underwent KT between 1983 and 2023 in our institution, six (1.3%) patients with SMID were identified. One patient received KT twice. All patients underwent living KT. Five patients used medical devices, including gastrostomy and a ventriculoperitoneal shunt, prior to KT. Perioperative complications, including hemothorax related to central venous catheter insertion, ventilator-associated pneumonia, and common iliac artery thrombosis requiring graftectomy, occurred in three patients. One patient required vesicostomy owing to refractory urinary tract infection. There was no significant difference in the graft survival rate between patients with SMID and those without SMID. One patient developed graft failure and died after selecting conservative kidney management. CONCLUSION Our study showed a favorable graft survival in children and adolescents with SMID who underwent KT. Although careful perioperative management and continued medical care are required, KT may be a viable option for these patients.

Barriers and supports for Indigenous youth and young adults with childhood- onset chronic health conditions transitioning from pediatric to adult healthcare: a qualitative study. Int J Equity Health 2024; 23:268. [PMID: 39695686 DOI: 10.1186/s12939-024-02343-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/22/2024] [Accepted: 11/21/2024] [Indexed: 12/20/2024] Open
Abstract
BACKGROUND This study examined the experiences of Indigenous youth and young adults with pediatric onset chronic health conditions who had or were about to transition from pediatric to adult healthcare services. Transition is the process by which youth develop the knowledge and self-management skills needed to manage their health condition, ideally beginning around age 12-13 and continuing until the mid-20s. There is a growing body of literature on healthcare transition, but there is an absence of literature on Indigenous youth, who face additional barriers to accessing healthcare relative to non-Indigenous Canadians. The primary objective of this study was to identify the supports and barriers for Indigenous youth with childhood-onset chronic health conditions transitioning from pediatric to adult healthcare services. METHODS The research was done in the province of Alberta, Canada, in collaboration with a Community Advisory Committee comprised of Indigenous healthcare providers, Elders and Knowledge Keepers and guided by a community-based participatory research approach. Semi-structured qualitative interviews (n = 46) were conducted with Indigenous youth, caregivers, and healthcare providers. There were three Talking Circles, two for youth (9 participants) and one for caregivers (6 participants). Three research assistants coded the transcripts thematically using NVivo. The key findings were presented to the Community Advisory Committee for feedback to validate the interpretation of the qualitative data. RESULTS The thematic findings include: (1) systemic inequalities exacerbate gaps in healthcare; (2) intergenerational trauma created unique barriers for Indigenous youth; (3) long-term relationships with care providers as a protective factor; (4) the incorporation of Indigenous worldviews into healthcare services to aid transition; and (5) assuming new responsibilities as an adult. The participants provided recommendations to improve healthcare service delivery including the need for Indigenous transition supports in community and improving education for healthcare practitioners about transition and Indigenous worldviews. CONCLUSION This study demonstrates the complexity of the transition experience for Indigenous youth with pediatric onset chronic health conditions. The identified barriers to successful transition could be addressed through systems level changes and the development of Indigenous specific transition support services. Such approaches need to be Indigenous-led and incorporate Indigenous culture, language, and teachings.

Abstract
BACKGROUND Complications following kidney transplantation elevate the risks of readmission and mortality. The aim of this study was to assess the association between the age-adjusted Charlson Comorbidity Index (ACCI) and postoperative complications among kidney transplant (KT) recipients. METHODS Between January 2015 and March 2021, a study involving 886 kidney transplant recipients at the Third Affiliated Hospital of Sun Yat-sen University was conducted. Postoperative complications were defined by the Clavien-Dindo Classification of Surgical Complications. Target Maximum Likelihood Estimation (TMLE) was employed to assess the association between ACCI and postoperative complications. The odds ratio (OR) was computed to determine the relationship between ACCI and postoperative complications. Subsequent interaction and stratified analyses were performed to assess the robustness of the findings. RESULTS Out of 859 KT participants ultimately included in the study, 30.7% were documented to have encountered postoperative complications. Participants with an ACCI value exceeding 3 exhibited a notably increased risk of postoperative complications following multivariable adjustment [aOR = 1.64, 95% CI [1.21,2.21], p = 0.001]. Congestive heart failure (OR = 16.18, 95% CI [1.98-132.17], p < 0.001), peripheral vascular disease (OR = 2.32, 95% CI [1.48-3.78], p < 0.001), and chronic obstructive pulmonary disease (OR = 6.05, 95% CI [2.95-12.39], p < 0.001) emerged as the top three preoperative comorbidities significantly linked to postoperative complications in ACCI. CONCLUSION An ACCI value exceeding 3 preoperatively constituted a risk factor for postoperative complications among KT patients.

Pediatr Transplant 2024; 28:e14873. [PMID: 39431585 DOI: 10.1111/petr.14873] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/13/2024] [Revised: 09/16/2024] [Accepted: 09/30/2024] [Indexed: 10/22/2024]
Abstract
BACKGROUND Much is reported regarding the detrimental effect of transfer to adult services for adolescent and young adult (AYA) kidney transplant (KT) recipients. However, AYA recipient age independent of time post-KT, and not relating to transfer of care, is also a strong predictor of graft loss. We assessed KT graft survival if experiencing solely pediatric (PO) or adult services (AO) versus transfer from pediatric to adult services (PTA). METHODS A retrospective cohort analysis of all first kidney transplant recipients between birth-24 years of age, from 2000 to 2019 in New Zealand. Participant identification and data were obtained via the Australia and New Zealand Dialysis and Transplantation registry. Primary outcome was graft survival stratified by service type. Cox proportional hazard modeling assessed independent risk factors of graft loss. RESULTS Two hundred forty-four children and AYA with a median follow-up of 7.3 years were included. Graft survival stratified by service provision group was not different. The incidence rate of graft loss was 37, 34, and 45 per 1000 persons per year for PO, PTA, and AO respectively. Crude age-specific graft failure rates were highest for 22-24-year-olds with inferior outcomes starting from age 16, peaking at 24 years. CONCLUSIONS Older adolescence and young adulthood reflect a high-risk period for KT loss. Transfer to adult services was not associated with worse graft survival compared to those experiencing either AO or PO alone. Improved models of care are needed to improve graft survival in this vulnerable population within New Zealand.

Abstract
BACKGROUND Kidney transplantation is the optimal renal replacement therapy for children with end-stage renal disease; however, delayed graft function (DGF), a common post-operative complication, may negatively impact the long-term outcomes of both the graft and the pediatric recipient. However, there is limited research on DGF in pediatric kidney transplant recipients. This study aims to develop a predictive model for the risk of DGF occurrence after pediatric kidney transplantation by integrating donor and recipient characteristics and utilizing machine learning algorithms, ultimately providing guidance for clinical decision-making. METHODS This single-center retrospective cohort study includes all recipients under 18 years of age who underwent single-donor kidney transplantation at our hospital between 2016 and 2023, along with their corresponding donors. Demographic, clinical, and laboratory examination data were collected from both donors and recipients. Univariate logistic regression models and differential analysis were employed to identify features associated with DGF. Subsequently, a risk score for predicting DGF occurrence (DGF-RS) was constructed based on machine learning combinations. Model performance was evaluated using the receiver operating characteristic curves, decision curve analysis (DCA), and other methods. RESULTS The study included a total of 140 pediatric kidney transplant recipients, among whom 37 (26.4%) developed DGF. Univariate analysis revealed that high-density lipoprotein cholesterol (HDLC), donor after circulatory death (DCD), warm ischemia time (WIT), cold ischemia time (CIT), gender match, and donor creatinine were significantly associated with DGF (P < 0.05). Based on these six features, the random forest model (mtry = 5, 75%p) exhibited the best predictive performance among 97 machine learning models, with the area under the curve values reaching 0.983, 1, and 0.905 for the entire cohort, training set, and validation set, respectively. This model significantly outperformed single indicators. The DCA curve confirmed the clinical utility of this model. CONCLUSIONS In this study, we developed a machine learning-based predictive model for DGF following pediatric kidney transplantation, termed DGF-RS, which integrates both donor and recipient characteristics. The model demonstrated excellent predictive accuracy and provides essential guidance for clinical decision-making. These findings contribute to our understanding of the pathogenesis of DGF.

Detection of Subclinical Rejection in Pediatric Kidney Transplantation: Current and Future Practices. Pediatr Transplant 2024; 28:e14836.

Abstract
INTRODUCTION The successes in the field of pediatric kidney transplantation over the past 60 years have been extraordinary. Year over year, there have been significant improvements in short-term graft survival. However, improvements in longer-term outcomes have been much less apparent. One important contributor has been the phenomenon of low-level rejection in the absence of clinical manifestations-so-called subclinical rejection (SCR). METHODS Traditionally, rejection has been diagnosed by changes in clinical parameters, including but not limited to serum creatinine and proteinuria. This review examines the shortcomings of this approach, the effects of SCR on kidney allograft outcome, the benefits and drawbacks of surveillance biopsies to identify SCR, and new urine and blood biomarkers that define the presence or absence of SCR. RESULTS Serum creatinine is an unreliable index of SCR. Surveillance biopsies are the method most utilized to detect SCR. However, these have significant drawbacks. New biomarkers show promise. These biomarkers include blood gene expression profiles and donor derived-cell free DNA; urine gene expression profiles; urinary cytokines, chemokines, and metabolomics; and other promising blood and urine tests. CONCLUSION Specific emphasis is placed on studies carried out in pediatric kidney transplant recipients. TRIAL REGISTRATION ClinicalTrials.gov: NCT03719339.

Interventions to support young adults and families with the healthcare transition between paediatric and adult nephrology health services: A systematic scoping review. J Pediatr Nurs 2024; 78:e346-e363. [PMID: 39153916 DOI: 10.1016/j.pedn.2024.07.026] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/13/2024] [Revised: 07/23/2024] [Accepted: 07/24/2024] [Indexed: 08/19/2024]
Abstract
BACKGROUND Healthcare transition can be challenging for young people and families living with chronic kidney conditions, including those with rare renal disorders who often have multi-systemic conditions, those who have undergone kidney transplantation, and those who face intense treatments like dialysis. Comprehensive, holistic healthcare transition interventions are required, encompassing physical, psychosocial, sexual, educational and vocational support. AIM This manuscript presents a systematic scoping review synthesising the healthcare transition interventions to support youth and families within nephrology services. METHODS This review followed Arksey and O'Malley's five-stage framework, updated by Levac, Colquhoun and O'Brien and the Joanna Briggs Institute. Six databases were systematically searched: CINAHL Plus with Full Text, Embase, PsycINFO, Web of Science, PubMed, and the Applied Social Sciences Index and Abstracts (ASSIA), locating 12,662 records. Following a systematic screening process, 28 articles met the inclusion criteria. Results were analysed systematically and presented using the PAGER framework developed by Bradbury-Jones et al. (2022). RESULTS Various interventions were sourced. Three broad patterns emerged: 1. Contextual Factors, e.g. cultural differences between paediatric and adult services; 2. Major Intervention Components, e.g. parental/familial/peer-to-peer support, and 3. Personal factors, e.g., self-management ability. CONCLUSION Few interventions are available to support youth with rare renal disorders, specifically. Future research must be directed at this cohort. Healthcare transition timing remains hotly contested, with additional guidance required to support decision-making. Finally, limited interventions have been evaluated for practice. IMPLICATIONS This review has provided various considerations/recommendations that should be taken into account when designing, implementing or evaluating future healthcare transition supports.

J Pediatr Nurs 2024; 77:e487-e494.

Abstract
PURPOSE The objective of this study was to investigate the experience of first- and second- generation immigrant youth living with chronic health conditions in Canada, their parents or caregivers, and healthcare and service providers who care for immigrant youth, regarding the transition from pediatric to adult healthcare. DESIGN AND METHODS We conducted semi-structured individual interviews and focus groups. Youth were 1st or 2nd generation immigrants, aged 16-25, with pediatric-onset chronic health conditions. Parents or caregivers had raised youth children as described. Providers delivered healthcare or other services to immigrant populations. Thematic analysis was conducted of all transcripts. RESULTS Twenty youth, 14 parents/caregivers and five service providers participated. Most participants described healthcare transition as very difficult to navigate. Two major themes emerged across participant narratives: 1. Barriers to transition: lack of family experience in Canada, language, discrimination, financial strain, stigma, and long wait times. Some of these barriers are specific to newcomer families, but others are generalizable to the Canadian population. 2. Facilitators of transition: youth independence, youth acting as cultural bridges within their families, and cross-sector support between healthcare, education, social work and settlement services. CONCLUSIONS Immigrant youth and their families face a broad range of barriers to healthcare transition. The collaborative nature of cross-sector support effectively addressed some of the barriers faced by newcomer families. PRACTICE IMPLICATIONS Clinicians should provide immigrant youth and their families with accessible information about the health condition and how to navigate the adult healthcare system prior to transition, particularly when language barriers exist.

Abstract
BACKGROUND There have been over 51 000 pediatric solid organ transplants since 1988 in the United States alone, leading to a growing population of long-term survivors who face complications of childhood organ failure and long-term immunosuppression. AIMS This is an educational review of existing literature. RESULTS Pediatric solid organ transplant recipients are at increased risk for risk for cardiovascular and kidney disease, skin cancers, and growth problems, though the severity of impact may vary by organ type. Pediatric recipients often are able to complete schooling, maintain a job, and form family and social networks in adulthood, though at somewhat lower rates than the general population, but face additional challenges related to neurocognitive deficits, mental health disorders, and discrimination. CONCLUSIONS Transplant centers and research programs should expand their focus to include long-term well-being. Increased collaboration between pediatric and adult transplant specialists will be necessary to better understand and manage long-term complications.

Abstract
Transplantation remains the gold-standard treatment for pediatric end-stage kidney disease. While living donor transplant is the preferred option for most pediatric patients, it is not the right choice for all. For those who have the option to choose between deceased donor and living donor transplantation, or from among multiple potential living donors, the transplant clinician must weigh multiple dynamic factors to identify the most optimal donor. This review will cover the key considerations when choosing between potential living donors and will propose a decision-making algorithm.

Optimizing the approach to monitoring allograft inflammation using serial urinary CXCL10/creatinine testing in pediatric kidney transplant recipients. Pediatr Transplant 2024; 28:e14718.

Abstract
BACKGROUND Urinary CXCL10/creatinine (uCXCL10/Cr) is proposed as an effective biomarker of subclinical rejection in pediatric kidney transplant recipients. This study objective was to model implementation in the clinical setting. METHODS Banked urine samples at a single center were tested for uCXCL10/Cr to validate published thresholds for rejection diagnosis (>80% specificity). The positive predictive value (PPV) for rejection diagnosis for uCXCL10/Cr-indicated biopsy was modeled with first-positive versus two-test-positive approaches, with accounting for changes associated with urinary tract infection (UTI), BK and CMV viremia, and subsequent recovery. RESULTS Seventy patients aged 10.5 ± 5.6 years at transplant (60% male) had n = 726 urine samples with n = 236 associated biopsies (no rejection = 167, borderline = 51, and Banff 1A = 18). A threshold of 12 ng/mmol was validated for Banff 1A versus no-rejection diagnosis (AUC = 0.74, 95% CI = 0.57-0.92). The first-positive test approach (n = 69) did not resolve a clinical diagnosis in 38 cases (55%), whereas the two-test approach resolved a clinical diagnosis in the majority as BK (n = 17/60, 28%), CMV (n = 4/60, 7%), UTI (n = 8/60, 13%), clinical rejection (n = 5/60, 8%), and transient elevation (n = 18, 30%). In those without a resolved clinical diagnosis, PPV from biopsy for subclinical rejection is 24% and 71% (p = .017), for first-test versus two-test models, respectively. After rejection treatment, uCXCL10/Cr level changes were all concordant with change in it-score. Sustained uCXCL10/Cr after CMV and BK viremia resolution was associated with later acute rejection. CONCLUSIONS Urinary CXCL10/Cr reliably identifies kidney allograft inflammation. These data support a two-test approach to reliably exclude other clinically identifiable sources of inflammation, for kidney biopsy indication to rule out subclinical rejection.

Abstract
Kidney transplantation provides the best form of kidney replacement therapy with improvement in quality of life and longevity. However, disparity exists in its availability, utilisation and outcomes, not only due to donor availability or financial constraints but also arising from the influence of biological sex and its sociocultural attribute i.e., Gender. Women make up the majority of kidney donors but are less likely to be counselled regarding transpantation, be waitlisted or receive living/deceased donor kidney. Biological differences also contribute to differences in kidney transplantation among the sexes. Women are more likely to be sensitised owing to pregnancy, especially in multiparous individuals, complicating donor compatibility. A heightened immune system in women, evidenced by more autoimmune illnesses, increases the risk of allograft rejection and loss. Differences in the pharmacokinetics of transplant drugs owing to biological variances could also contribute to variability in outcomes. Transgender medicine is also increasingly becoming a relevant topic of study, providing greater challenges in the form of hormonal manipulations and anatomic changes. It is thus important to determine and study transplantation and its nuances in this backdrop to be able to provide relevant sex and gender-specific interventions and design better practices for optimum kidney transplant utilisation and outcomes.

Abstract
Already a challenging condition to define, adult congenital heart disease (ACHD) -associated heart failure (HF) often incorporates specific anatomies, including intracardiac and extracardiac shunts, which require rigorous diagnostic characterization and heighten the importance of clinicians proactively considering overall hemodynamic impacts of using specific therapies. The presence of elevated pulmonary vascular resistance dramatically increases the complexity of managing patients with ACHD-HF. Total circulatory management in patients with ACHD-HF requires input from multidisciplinary care teams and thoughtful and careful utilization of medical, interventional, and surgical approaches.

Abstract
BACKGROUND Little is known about the time-varying determinants of kidney graft failure in children. METHODS We performed a retrospective study of primary pediatric kidney transplant recipients (younger than 18 years) from the Eurotransplant registry (1990-2020). Piece-wise exponential additive mixed models were applied to analyze time-varying recipient, donor, and transplant risk factors. Primary outcome was death-censored graft failure. RESULTS We report on 4528 kidney transplantations, of which 68% with deceased and 32% with living donor. One thousand six hundred and thirty-eight recipients experienced graft failure, and 168 died with a functioning graft. Between 2011 and 2020, the 5-year graft failure risk was 10% for deceased donor and 4% for living donor kidney transplant recipients. Risk of graft failure decreased five-fold from 1990 to 2020. The association between living donor transplantation and the lower risk of graft failure was strongest in the first month post-transplant (adjusted hazard ratio, 0.58; 95% confidence interval, 0.46 to 0.73) and remained statistically significant until 12 years post-transplant. Risk factors for graft failure in the first 2 years were deceased donor younger than 12 years or older than 46 years, potentially recurrent kidney disease, and panel-reactive antibody >0%. Other determinants of graft failure included dialysis before transplantation (until 5 years post-transplant), human leukocyte antigen mismatch 2-4 (0-15 years post-transplant), human leukocyte antigen mismatch 5-6 (2-12 years post-transplant), and hemodialysis (8-14 years post-transplant). Recipients older than 11 years at transplantation had a higher risk of graft failure 1-8 years post-transplant compared with other age groups, whereas young recipients had a lower risk throughout follow-up. Analysis of the combined effect of post-transplant time and recipient age showed a higher rate of graft failure during the first 5 years post-transplant in adolescents compared with young transplant recipients. In contrast to deceased donor younger than 12 years, deceased donor older than 46 years was consistently associated with a higher graft failure risk. CONCLUSIONS We report a long-term inverse association between living donor kidney transplantation and the risk of graft failure. The determinants of graft failure varied with time. There was a significant cumulative effect of adolescence and time post-transplant. The ideal donor age window was dependent on time post-transplant.

Abstract
BACKGROUND Cardiac allograft vasculopathy (CAV) is an important cause of mortality after pediatric heart transplantation (HT) but there is a paucity of data regarding its incidence and impact on survival in pediatric recipients transitioned to adult care. METHODS We conducted a retrospective review of consecutive pediatric HT patients from 1989 to 2017 at the Hospital for Sick Children who transitioned to adult care at ≥18 years at Toronto General Hospital. We evaluated the incidence of International Society of Heart and Lung Transplantation CAV grade ≥1 using competing risk models. We assessed the association between all-cause mortality and CAV using Cox proportional hazards and used Kaplan Meier methods to evaluate all-cause mortality stratified by CAV and transplant era (1989-2001, 2002-2017). RESULTS Ninety-six patients were transitioned to adult care by January 2022, of which 53 underwent repeat coronary angiography as adults. CAV was newly diagnosed in 49% patients after transition to adult care. The overall incidence of CAV was 3.9 cases per 100 person-years. There was no difference in the adjusted incidence of CAV according to transplant era (subdistribution hazard ratios = 1.17, 95% confidence interval (CI) 0.54-2.66). CAV was associated with a higher risk of death in the early era (hazard ratio (HR) 10.29, 95% CI 2.16-49.96), but not in the recent era (HR 1.61, 95% 0.35-7.47). CONCLUSIONS There is a role for continued CAV surveillance after the transition to adult care. The implications of diagnosing CAV after the transition to adult care require further study, particularly because the risk of death in pediatric HT recipients diagnosed with CAV in the more recent era may be attenuated compared to the earlier HT era.

Dobbels F, Wray J. Medication adherence in pediatric kidney transplantation: How to build a bridge over troubled water. Pediatr Transplant 2024; 28:e14663. [PMID: 38012099 DOI: 10.1111/petr.14663] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/26/2023] [Revised: 10/13/2023] [Accepted: 11/16/2023] [Indexed: 11/29/2023]
Abstract
Adhering to the immunosuppressive regimen remains one of the biggest challenges for children and adolescents after kidney transplantation. The first paper on nonadherence, co-authored by Dr. Fine, appeared in Pubmed over 45 years ago. Since then, many clinicians and researchers tried to better understand nonadherence and are looking for effective ways to support young people in implementing the complex medication regimen in their daily lives. As a tribute to Dr. Fine, we conducted a comprehensive review providing an overview of adherence-enhancing interventions in the field of pediatric kidney transplantation, thereby focusing on strategies that not only are effective but can also be embedded in daily clinical practice successfully and sustainably. This overview is preceded by a discussion about how to find out who is in need of supportive interventions. We will also argue that interventions should already start before pediatric kidney transplantation and discuss how to decide whether or not a young patient with nonadherence-induced graft loss should undergo retransplantation. We hope this comprehensive overview will rekindle the hope that we can finally turn the tide and beat one of pediatric kidney transplantation's main enemies.

Trajectories of eGFR after kidney transplantation according to trajectories of eGFR prior to kidney replacement therapies in children with chronic kidney disease. Pediatr Nephrol 2023; 38:4157-4164. [PMID: 37353626 PMCID: PMC10591981 DOI: 10.1007/s00467-023-06056-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/10/2023] [Revised: 06/02/2023] [Accepted: 06/08/2023] [Indexed: 06/25/2023]
Abstract
BACKGROUND In children with chronic kidney disease (CKD), certain risk factors are associated with faster eGFR decline and earlier kidney failure. Whether these factors have lingering effects on post-transplant eGFR trajectory remains unclear. We characterized pre- and post-transplant eGFR trajectories in pediatric kidney transplant recipients by their pre-kidney replacement therapy (KRT) risk factors. METHODS We studied eGFR trajectories before KRT initiation and after transplantation among Chronic Kidney Disease in Children (CKiD) Study participants. We used mixed-effects models to compare pre-KRT versus post-transplant eGFR trajectories within individual participants by 7 pre-KRT risk factors: glomerular/non-glomerular etiology, race, preemptive transplant, proteinuria, albuminuria, and systolic/diastolic blood pressure (SBP/DBP). RESULTS We analyzed 1602 pre-KRT and 592 post-transplant eGFR measurements from 246 transplant recipients. Mean annual eGFR decline was decreased from 18.0% pre-KRT (95%CI, 16.1-19.8) to 5.0% post-transplant (95%CI, 3.3-6.7). All 7 pre-KRT risk factors showed strong associations with faster pre-KRT eGFR decline, but not with post-transplant eGFR decline; only albuminuria, high SBP, and high DBP reached statistical significance with notably attenuated associations. In our multivariable model of the pre-KRT risk factors, post-transplant eGFR decline was more rapid only when albuminuria and high SBP were both present. CONCLUSIONS eGFR decline substantially slows down after transplant even among children with rapidly progressing forms of CKD. Nonetheless, those who had albuminuria and high SBP before KRT might continue to show faster eGFR decline after transplant, specifically when both risk factors were present. This subgroup might benefit from intensive pre-transplant management for at least one of the two risk factors. A higher resolution version of the Graphical abstract is available as Supplementary information.

Abstract
BACKGROUND Chronic kidney disease (CKD) is a relatively rare childhood disease that is associated with a wide array of medical comorbidities. Roughly half of all pediatric patients acquire CKD due to congenital anomalies of the kidneys and urinary tract, and of those with congenital disease, 50% will progress to end-stage kidney disease (ESKD) necessitating a kidney transplantation. The medical sequelae of advanced CKD/ESKD improve dramatically following successful kidney transplantation; however, the impact of kidney transplantation on neurocognition in children is less clear. It is generally thought that cognition improves following kidney transplantation; however, our knowledge on this topic is limited by the sparsity of high-quality data in the context of the relative rarity of pediatric CKD/ESKD. METHOD We conducted a narrative review to gauge the scope of the literature, using the PubMed database and the following keywords: cognition, kidney, brain, pediatric, neurocognition, intelligence, executive function, transplant, immunosuppression, and neuroimaging. RESULTS There are few published longitudinal studies, and existing work often includes wide heterogeneity in age at transplant, variable dialysis exposure/duration prior to transplant, and unaccounted cofounders which persist following transplantation, including socio-economic status. Furthermore, the impact of long-term maintenance immunosuppression on the brain and cognitive function of pediatric kidney transplant (KT) recipients remains unknown. CONCLUSION In this educational review, we highlight what is known on the topic of neurocognition and neuroimaging in the pediatric KT population.

Validation of a prediction system for risk of kidney allograft failure in pediatric kidney transplant recipients: An international observational study. Am J Transplant 2023; 23:1561-1569.

Abstract
Predicting long-term kidney allograft failure is an unmet need for clinical care and clinical trial optimization in children. We aimed to validate a kidney allograft failure risk prediction system in a large international cohort of pediatric kidney transplant recipients. Patients from 20 centers in Europe and the United States, transplanted between 2004 and 2017, were included. Allograft assessment included estimated glomerular filtration rate, urine protein-to-creatinine ratio, circulating antihuman leukocyte antigen donor-specific antibody, and kidney allograft histology. Individual predictions of allograft failure were calculated using the integrative box (iBox) system. Prediction performances were assessed using discrimination and calibration. The allograft evaluations were performed in 706 kidney transplant recipients at a median time of 9.1 (interquartile range, 3.3-19.2) months posttransplant; mean estimated glomerular filtration rate was 68.7 ± 28.1 mL/min/1.73 m2, and median urine protein-to-creatinine ratio was 0.1 (0.0-0.4) g/g, and 134 (19.0%) patients had antihuman leukocyte antigen donor-specific antibodies. The iBox exhibited accurate calibration and discrimination for predicting the outcomes up to 10 years after evaluation, with a C-index of 0.81 (95% confidence interval, 0.75-0.87). This study confirms the generalizability of the iBox to predict long-term kidney allograft failure in children, with performances similar to those reported in adults. These results support the use of the iBox to improve patient monitoring and facilitate clinical trials in children.

Ther Drug Monit 2023; 45:591-598. [PMID: 36823705 DOI: 10.1097/ftd.0000000000001087] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/07/2022] [Accepted: 12/14/2022] [Indexed: 02/25/2023]
Abstract
BACKGROUND The Immunosuppressant Bayesian Dose Adjustment web site aids clinicians and pharmacologists involved in the care of transplant recipients; it proposes dose adjustments based on the estimated area under the concentration-time curve (AUCs). Three concentrations (T 20 min , T 1 h , and T 3 h ) are sufficient to estimate mycophenolic acid (MPA) AUC 0-12 h in pediatric kidney transplant recipients. This study investigates mycophenolate mofetil (MMF) doses and MPA AUC values in pediatric kidney transplant recipients, and target exposure attainment when the proposed doses were followed, through a large-scale analysis of the data set collated since the inception of the Immunosuppressant Bayesian Dose Adjustment web site. METHODS In this study, 4051 MMF dose adjustment requests, corresponding to 1051 patients aged 0-18 years, were retrospectively analyzed. AUC calculations were performed in the back office of the Immunosuppressant Bayesian Dose Adjustment using published Bayesian and population pharmacokinetic models. RESULTS The first AUC request was posted >12 months posttransplantation for 41% of patients. Overall, only 50% had the first MPA AUC 0-12 h within the recommended 30-60 mg.h/L range. When the proposed dose was not followed, the proportion of patients with an AUC in the therapeutic range for MMF with cyclosporine or tacrolimus at the subsequent request was lower (40% and 45%, respectively) than when it was followed (58% and 60%, respectively): P = 0.08 and 0.006, respectively. Furthermore, 3 months posttransplantation, the dispersion of AUC values was often lower at the second visit when the proposed doses were followed, namely, P = 0.03, 0.003, and 0.07 in the 4 months-1 year, and beyond 1 year with <6-month or >6-month periods between both visits, respectively. CONCLUSIONS Owing to extreme interindividual variability in MPA exposure, MMF dose adjustment is necessary; it is efficient at reducing such variability when based on MPA AUC.

Abstract
Health-care transition (HCT) from pediatric-centered to adult-oriented health-care setting is more than a simple transfer of care. It is a carefully planned movement specially tailored for the needs of adolescents and young adults (AYAs). Similar to other chronic diseases, the need for HCT for AYAs with kidney disease has been well established by the International Society of Nephrology (ISN) and the International Pediatric Nephrology Association (IPNA) consensus statements since 2011. However, successful HCT in India and other low- and middle-income countries (LMICs) has been limited. Undertaking the HCT program in India requires involvement of many stakeholders, that is, AYAs, parents/caregivers, health-care providers, and the health-care system. In this article, we discuss the need for HCT, the challenges faced during the transition, and the recommended models for HCT in kidney care. We focus on the unique challenges faced in India and conclude with practical suggestions to implement HCT in our setting.

Abstract
PURPOSE There is little evidence on whether smartphone technology influences transition readiness among adolescents with heart disease. Just TRAC it! is a method of using existing smartphone features (Notes, Calendar, Contacts, Camera) to manage personal health. We evaluated the impact of Just TRAC it! on self-management skills. METHODS Randomized clinical trial of 16-18 year-olds with heart disease. Participants were randomly allocated 1:1 to either usual care (education session) or intervention (education session including Just TRAC it!). The primary outcome was change in TRANSITION-Q score between baseline, 3 and 6 months. Secondary outcomes were frequency of use and perceived usefulness of Just TRAC it! Analysis was intention-to-treat. RESULTS We enrolled 68 patients (41% female, mean age 17.3 years), 68% having previous cardiac surgery and 26% had cardiac catheterization. TRANSITION-Q scores were similar at baseline and increased over time in both groups but were not significantly different between groups. Each additional point at the baseline score brought, on average, a 0.7-point increase in TRANSITION-Q score (95% CI 0.5-0.9) at each of 3 and 6 months. The Camera, Calendar and Notes apps were reported as most useful. All intervention participants would recommend Just TRAC it! to others. DISCUSSION A nurse-led transition teaching with versus without Just TRAC it! improved transition readiness, with no significant difference between groups. Higher baseline TRANSITION-Q scores were associated with greater increase in scores over time. Participants had a positive reception to Just TRAC it! and would recommend it to others. Smartphone technology may be useful in transition education.

Abstract
Kidney transplantation is the treatment of choice for all patients with end-stage kidney disease, including pediatric patients. Graft survival in pediatrics was lagging behind adults, but now is comparable with the adult cohort. Although many of the protocols have been adopted from adults, there are issues unique to pediatrics that one should be aware of to take care of this population. These issues include recipient size consideration, increased incidence of viral infections, problems related to growth, common occurrence of underlying urological issues, and psychosocial issues. This article addresses the similarities and differences in renal transplantation, from preparing a patient for transplant, the transplant process, to post-transplant complications.

Abstract
Kidney transplantation has been the optimal treatment for end-stage kidney disease for almost 70 years, with increasing frequency over this period. Despite the prevalence of the procedure, allograft rejection continues to impact transplant recipients, with consequences ranging from hospitalization to allograft failure. Rates of rejection have declined over time, which has been largely attributed to developments in immunosuppressive therapy, understanding of the immune system, and monitoring. Developments in these therapies, as well as an improved understanding of rejection risk and the epidemiology of rejection, are dependent on a foundational understanding of the pathophysiology of rejection. This review explains the interconnected mechanisms behind antibody-mediated and T-cell-mediated rejection and highlights how these processes contribute to outcomes and can inform future progress.

Abstract
Background Upper extremity vascularized composite allotransplantation is a life-enhancing reconstructive treatment option that aims to improve recipients' quality of life and maximize function. This study assessed upper extremity vascularized composite allotransplantation patient selection criteria perceptions among individuals with upper extremity limb loss. The perceptions of individuals with upper extremity limb loss on patient selection criteria may enable vascularized composite allotransplantation centers to improve criteria to avoid mismatched expectations about the posttransplant vascularized composite allotransplantation experience and outcomes. Realistic patient expectations may increase patient adherence, improve outcomes, and reduce vascularized composite allotransplantation graft loss. Methods We conducted in-depth interviews with civilian and military service members with upper extremity limb loss and upper extremity vascularized composite allotransplantation candidates, participants, and recipients from three US institutions. Interviews assessed perceptions of patient selection criteria for suitability as a candidate for upper extremity vascularized composite allotransplantation. Thematic analysis was used to analyze qualitative data. Results A total of 50 individuals participated (66% participation rate). Most participants were male (78%), White (72%), with a unilateral limb loss (84%), and a mean age of 45 years. Six themes emerged regarding upper extremity vascularized composite allotransplantation patient selection criteria, including support for candidates who: (1) are of younger age, (2) are in good physical health, (3) have mental stability, (4) are willing to "put in the work," (5) have specific amputation characteristics, and (6) have sufficient social support. Patients had preferences about selecting candidates with unilateral versus bilateral limb loss. Conclusions Our findings suggest that numerous factors, including medical, social, and psychological characteristics, inform patients' perceptions of patient selection criteria for upper extremity vascularized composite allotransplantation. Patient perceptions of patient selection criteria should inform the development of validated screening measures that optimize patient outcomes.

Transplantation 2023; 107:1206-1212. [PMID: 36476728 PMCID: PMC10125107 DOI: 10.1097/tp.0000000000004431] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/21/2021] [Revised: 04/01/2022] [Accepted: 04/07/2022] [Indexed: 12/12/2022]
Abstract
BACKGROUND The transition from pediatric to young adult care is a vulnerable period for the renal transplant patient. We aimed to identify medication nonadherence (noninitiation, nonimplementation, and nonpersistence) and graft loss rates among adolescents and young adults and elucidate the influence of the transition phase on transplant outcomes. METHODS A retrospective nationwide cohort analysis of all renal transplantations in Norway from 2000 to 2020 was performed. Data were retrieved from the Norwegian Renal Registry, and adherence data from hospital charts. Patients transplanted aged <50 y, with functioning graft at 6 mo, were included. Recipients transplanted aged <26 y were compared with recipients transplanted aged 26-50 y. Graft loss, acute rejection, and development of de novo donor-specific antibodies were assessed in relation to the transition phase, defined as 14-26 y. RESULTS Data from 1830 kidney recipients were included: 371 (20%) transplanted <26 y (64% male, 68% living donor) versus 1459 transplanted 26-50 y (63% male, 44% living donor). There were 298 graft losses, 78 (21%) in the <26-y group versus 220 (15%) in the 26- to 50-y group. During the transition phase, 36 grafts were lost, 29 (81%) after transfer to the adult service. Medication nonadherence was the reason for 58% (21 of 36) of the losses during the transition phase, versus 12% (27 of 220) in the 26- to 50-y group ( P < 0.001). The 5-y graft survival rate was 89% (95% confidence interval, 85%-92%) and 94% (92%-95%), respectively ( P = 0.01). CONCLUSIONS Nonadherence was verified as the main cause of kidney graft loss in the transition phase.

Transplant Rev (Orlando) 2023; 37:100760.

Abstract
BACKGROUND AND OBJECTIVES Adherence to medical treatment following a kidney transplant is particularly challenging during adolescence and young adulthood. There is increasing evidence of the benefits of the use of computer and mobile technology (labelled as eHealth hereafter) including serious gaming and gamification in many clinical areas. We aimed to conduct a systematic review of such interventions designed to improve self-management skills, treatment adherence and clinical outcomes in young kidney transplant recipients aged 16 to 30 years. METHOD The Cochrane Library, MEDLINE, EMBASE, PsychINFO, SCOPUS and CINAHL databases were searched for studies published between 01 January 1990 and 20 October 2020. Articles were short-listed by two independent reviewers based on pre-defined inclusion/exclusion criteria. Reference lists were screened and authors of published conference abstracts contacted. Two reviewers independently appraised selected articles, systematically extracted data and assessed the quality of individual studies (CASP and SORT). Thematic analysis was used for evidence synthesis; quantitative meta-analysis was not possible. RESULTS A total of 1098 unique records were identified. Short-listing identified four eligible studies, all randomized controlled trials (n = 266 participants). Trials mainly focused on mHealth applications or electronic pill dispensers (mostly for patients >18 years old). Most studies reported on clinical outcome measures. All showed improved adherence but there were no differences in the number of rejections. Study quality was low for all four studies. CONCLUSIONS The findings of this review suggest that eHealth interventions can improve treatment adherence and clinical outcomes for young kidney transplant patients. More robust and high-quality studies are now needed to validate these findings. Future studies should also extend beyond short-term outcomes, and consider cost of implementation. The review was registered with PROSPERO (CRD42017062469).

Differences in medication adherence by sex and organ type among adolescent and young adult solid organ transplant recipients. Pediatr Transplant 2023; 27:e14446.

Abstract
BACKGROUND Identification of differences in medication adherence by sex or organ type may help in planning interventions to optimize outcomes. We compared immunosuppressive medication adherence between males and females, and between kidney, liver and heart transplant recipients. METHODS This multicenter study of prevalent kidney, liver and heart transplant recipients 14-25 years assessed adherence 3 times (0, 3, 6 months post-enrollment) with the BAASIS self-report tool. At each visit, participants were classified as adherent if they missed no doses in the prior 4 weeks and non-adherent otherwise. Adherence was also assessed using the coefficient of variation (CV) of tacrolimus trough levels; CV < 30% was classified as adherent. We used multivariable mixed effects logistic regression models adjusted for potential confounders to compare adherence by sex and by organ. RESULTS Across all visits, males (n = 150, median age 20.4 years, IQR 17.2-23.3) had lower odds of self-reported adherence than females (n = 120, median age 19.8 years, IQR 17.1-22.7) (OR 0.41, 95% CI 0.21-0.80) but higher odds of adherence by tacrolimus CV (OR 2.50, 95% CI 1.30-4.82). No significant differences in adherence (by self-report or tacrolimus CV) were noted between the 184 kidney, 58 liver, and 28 heart recipients. CONCLUSION Females show better self-reported adherence than males but greater variability in tacrolimus levels. Social desirability bias, more common in females than males, may contribute to better self-reported adherence among females. Higher tacrolimus variability among females may reflect biologic differences in tacrolimus metabolism between males and females rather than sex differences in adherence. There were no significant differences in adherence by organ type.

Abstract
Renal transplantation is the gold-standard treatment for adolescents and young adults with end-stage renal disease. Despite enjoying excellent short-term outcomes, they suffer the worst rates of premature transplant function loss. Health behaviors: such as lack of adherence to immunosuppressive medications, are felt to be the major contributory factor. Understanding the educational needs of young renal transplant recipients allows healthcare practitioners to better support patients in managing their chronic disease. The aim of this scoping review was to understand what is known about their educational needs. A scoping review methodology was followed. Following an online search, study titles, and abstracts were screened for eligibility, followed by full-text assessment and data extraction. Data were qualitatively analyzed using thematic analysis. A total of 29 studies were included in the scoping review. In young people who struggled with self-management, three themes were identified (1) the Needs of the disrupted youth, (2) the Needs of the disorganized youth (3) the Needs of the distressed youth. There was a paucity of research to identify the protective factors that enable young recipients to successfully manage their health. This review outlines current knowledge of the patient education needs of young transplant recipients. It also highlights remaining research gaps that will need to be addressed with future research.

Abstract
INTRODUCTION Envarsus XR® (LCPT), a once daily dosage formulation of tacrolimus, is an FDA-approved medication in adult renal transplant recipients (RTRs). There are limited data on its pharmacokinetics (PK) in adolescent RTRs. We report here the PK profile of LCPT in adolescent RTRs. METHODS The dose of LCPT was determined using a dose conversion ratio targeting 0.7 relative to the total daily immediate-release tacrolimus (IR-Tac) dose. On day 7 after converting to LCPT, patients had an abbreviated PK assessment with sampling at: 0 h (pre-dose), 8-, and 12-h post-dose. The PK data analysis was performed using Bayesian estimators. Our results were compared to those of published adult PK data for LCPT and pediatric PK data for IR-Tac and extended release tacrolimus (ER-Tac) formulation (Advagraf). RESULTS PK data from three adolescent patients on LCPT were evaluated. The mean (±SD) area under the time-concentration curve (AUC) was 240 (±20.22) h*ng/mL. The mean Tmax was 9.01 ± 2.12 h, and the % fluctuation was 77.71 ± 3.96%. The AUC, Tmax , and % fluctuation were similar to reported results in adult patients taking LCPT. The AUC was higher and the Tmax was longer than what has been reported in pediatric patients taking IR-Tac and ER-Tac. In addition, the LCPT group showed a lower % fluctuation than patients receiving ER-Tac. CONCLUSION The PK evaluation of LCPT in adolescent RTRs showed similar results to adults. Adolescents taking LCPT had a higher AUC, a more attenuated Tmax , and a lower fluctuation than that seen with ER-Tac in pediatrics.

Abstract
Survival of pediatric kidney transplant recipients has improved over the past six decades. However, adolescents and young adults still have the highest graft failure rates of any age group. There is a growing need for well-designed transition programs to ensure the successful integration of young adults into adult society with eventual transfer of care and management in adult transplant centers. In this review, we discuss the risk factors contributing to the high risk of kidney graft failure observed between 17 and 24 years of age, including the role of transfer from pediatric to adult care. We also address the unique challenges of adolescents with kidney transplant: the impact of chronic kidney disease on neurocognition, age-related changes in immune activity, and suboptimal adherence during the transition process. We then describe strategies to mitigate these risks by designing developmentally appropriate transition programs, and review the evidence supporting the benefits of well-designed multidisciplinary transition programs.

Abstract
PURPOSE Teenagers experience high rates of rejection and organ failure after heart transplantation due to non-adherence to medications, poor transition into adult care, and difficulties communicating with adults including healthcare providers. This project aimed to creatively bridge this gap-including teenage patients, their parents, and healthcare providers in the development of a new resource meant to motivate teenage heart-transplant-patients to take interest and ownership of their long-term health. METHODS Four teenage heart-transplanted patients, four parents, and three healthcare providers provided insight into relevant content for an educational resource through semi-standardized questionnaires and interviews. Their input guided the style and substance of the resource developed under the supervision of Fine Arts professors and the pediatric heart transplant team. RESULTS Parents and healthcare providers were concerned about teenagers' health choices and lack of perspective while patients were more bothered by parental nagging and being careful about infections than worrying about post-transplant risks. The resource that was developed therefore used subtlety within a narrative medium: a graphic novel that involved mutant worms, secret plots, and daring escapes, to address identified medical concerns and encouragements without triggering teenage resistance to instruction. CONCLUSION The discrepancies between the priorities of healthcare providers, parents, and teenage heart-transplant-patients illustrate the significance of basing resource-development on input from the target population. We developed the first graphic novel written for teenage heart-transplant-patients with patient input and interdisciplinary cooperation, using the subtlety of a narrative medium as a model for integrating medical content within an appealing, motivational, patient-centered, and age-appropriate resource.

Abstract
BACKGROUND Pediatric kidney transplantation entails a well-timed transition from pediatric to adult medical care. We aimed to construct a structured transition protocol and evaluate its impact on transfer-related psychosocial problems in Slovenian patients with kidney transplants. METHODS Individual transition-related perceptions of our patients and their parents were first assessed, and the gathered information was used to establish a country-specific transition protocol. Eleven kidney transplant patients qualified for actual transfer and were considered for further analysis. Comprehension and attitude towards transfer, coping strategies, personality resilience, behavioral, and emotional problems were assessed using questionnaires and established psychological tools before and after the completed transfer. The results were compared and analyzed. RESULTS Ten of the eleven eligible patients were transferred to adult services between April 2020 and January 2021. The median age at enrollment was 19.7 years (range: 18.2-22.8 years). The most frequent concerns regarding upcoming health care were worse accessibility (50%), less supportive and less committed healthcare providers (40%), and deterioration of medical condition (10.0%). After the completed protocol-guided transfer, the patients declared to have no further concerns or worries. Before transfer, 28.9% of the patients' responses rated the amount and relevance of received information and counseling as "Adequate" or "Very adequate," whereas, after the transfer, the proportion of positive responses increased to 48.9%. Anxiety and withdrawn depressive symptoms were the predominant emotional problems before transfer. Their prevalence decreased after the completed transfer. CONCLUSIONS Our results suggest that transfer-related anxieties and concerns can be significantly reduced by applying a structured transition protocol in transplant patients.

Abstract
Successful outcomes in pediatric kidney transplantation require the involvement of the transplant team as well as recipients and their caregivers. Enhancing patient and family understanding of the disease and of post-transplant care can result in improved adherence and outcomes. Educational strategies should aim to be broad, understandable, innovative, and inclusive while maintaining a tailored approach to individualized care. Teaching should not be viewed as a one-time event but rather as an ongoing conversation throughout the duration of care, emphasizing different aspects throughout the patient's various developmental stages. The following review article discusses the content and methods of post-transplant education.

Abstract
RATIONALE & OBJECTIVE Nonadherence to medical regimens increases the risk of graft loss among adolescent and young adult recipients of kidney transplants. Interventions that improve adherence may decrease rejection rates, but their perceived costs are a barrier to clinical implementation. We developed a model to assess the cost-effectiveness of an adherence promotion strategy, the Medication Adherence Promotion System (MAPS). STUDY DESIGN Simulation-based. Data sources included published articles indexed in Medline or referenced in bibliographies of relevant English-language articles. Data on costs and outcomes were taken from a single clinical center. SETTING & POPULATION US adolescent patients after their first kidney transplant. INTERVENTION Usual posttransplant care versus usual care plus MAPS. OUTCOME Effectiveness measured in quality-adjusted life years (QALYs) and costs measured in 2020 US dollars. MODEL, PERSPECTIVE, & TIMEFRAME Markov state transition decision model. We used a health care system perspective with a lifelong time horizon. RESULTS In the base-case analysis, MAPS was more effective and less costly than usual care. MAPS cost $9,106 per patient less than usual care and resulted in a gain of 0.32 QALYs. In probabilistic sensitivity analyses, MAPS was cost saving 100% of the time. Extending results to a program level with 100 patients, any adherence promotion intervention similar in effectiveness to MAPS would cost less than $50,000/QALY if the start-up costs were <$2.5 million and annual costs <$188,000. Strategies with costs similar to MAPS that reduce the risk of rejection by as little as 3% would also have similar cost-effectiveness. LIMITATIONS Estimates of components and costs for MAPS were based on a single center. CONCLUSIONS Adherence promotion strategies with costs similar to MAPS can be cost-effective as long as they reduce rejection rates by at least 3%. This model can be applied to study the cost-effectiveness of adherence promotion strategies with varying costs and outcomes.

Sex differences in the likelihood of pre-emptive living donor kidney transplantation, and outcomes after kidney transplantation in children and adolescents. Pediatr Transplant 2022; 26:e14224. [PMID: 35014131 DOI: 10.1111/petr.14224] [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: 10/03/2021] [Revised: 12/16/2021] [Accepted: 12/26/2021] [Indexed: 10/19/2022]
Abstract
BACKGROUND Data on sex-based disparities in children with kidney failure and outcomes after kidney transplantation are relatively sparse. This study examined the association between sex differences and the odds of receiving a pre-emptive living donor kidney transplantation, and post-transplant outcomes in children and adolescents. METHODS We studied all patients (aged <20 years) who commenced kidney replacement therapy (KRT) between 2002 and 2017 using data from the ANZDATA Registry. Factors associated with graft loss and acute rejection after transplantation were assessed using multivariable Cox regression model. Differences in the odds of receiving a pre-emptive live donor transplant between sexes were assessed using adjusted logistic regression. RESULTS Of the 757 children transplanted during the study period, 497 (65.7%) received a live donor kidney (163, 21.5% pre-emptive). In total, 168 (22.2%) patients experienced graft loss and 213 (28.1%) patients experienced a first episode of acute rejection during the median follow-up period of 6.9 years (IQR 3.5-11.5 years). There were no differences in the rates of graft loss or acute rejection by sex. Compared with boys, the adjusted hazard ratios (aHR) (95% confidence interval) for graft loss and acute rejection in girls were 0.97 (0.71-1.33) and 1.09 (0.82-1.44), respectively. Among children who received living donor kidney transplants, there were no sex differences in the odds of receiving a pre-emptive transplant (adjusted odds ratio (aOR) 0.90 (95% CI 0.56-1.45)). CONCLUSIONS No sex differences were observed in the odds of receiving a pre-emptive living donor kidney transplant or outcomes after kidney transplantation.

Pediatr Transplant 2022; 26:e14280. [PMID: 35388604 DOI: 10.1111/petr.14280] [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: 05/24/2021] [Revised: 03/15/2022] [Accepted: 03/26/2022] [Indexed: 11/28/2022]
Abstract
BACKGROUND Adolescent and young adult (AYA) solid organ transplant recipients experience worsening medical outcomes during transition to adult healthcare. Current understanding and definitions of transition success emphasize first initiation of appointment attendance in adult healthcare; however, declines in attendance over time after transfer remain possible, particularly as AYAs are further removed from their pediatric provider and assume greater independence in their care. METHODS The current study assessed health-care utilization, medical outcomes, and transition success among 49 AYA heart, kidney, or liver recipients recently transferred to adult healthcare. Differences in outcomes were examined along two transition success criteria: (1) initial engagement in adult healthcare within 6 or 12 months of last pediatric appointment and (2) retention in adult healthcare over 3 years following last pediatric appointment. Growth curve modeling examined change in attendance over time. RESULTS Successful retention in adult healthcare was significantly related to more improved clinical outcomes, including decreased number and duration of hospitalizations and greater medication adherence, as compared to initial engagement. Significant declines in appointment attendance over 3 years were noted, and individual differences in declines were not accounted for by age at transfer or time since transplant. CONCLUSIONS Findings underscore support for AYAs after transfer, as significant declines in attendance were noted after initiating adult care. Clinical care teams should examine transition success longitudinally to address changes in health-care utilization and medical outcomes. Attention to interventions and administrative support aimed at maintaining or increasing attendance and identifying risk factors and intervention for unsuccessful transition is warranted.

Abstract
BACKGROUND Renal transplantation is considered the gold standard treatment for end-stage kidney disease. Adolescent and young adult kidney transplant recipients have the highest rate of graft loss amongst transplanted patients. It is largely accepted this is due to psychosocial and behavioural difficulties, which impact adherence to prescribed therapies. This phenomenon is not isolated to a particular healthcare system having been observed in multiple countries across different continents. It is a global issue of concern. We sought to review the psychosocial needs of these patients, and the interventions designed to meet these needs. METHODS A scoping review was conducted based on Arksey and O'Malley's six-stage framework. Eligibility criteria included primary studies of any type that investigated the psychosocial needs of adolescent and/or young adult renal transplant recipients or studies which examined interventions designed to address these needs. Search strategies were developed and conducted on PsycINFO, PubMed, Embase, and CINAHL. Articles meeting the inclusion criteria were critically reviewed using a descriptive-analytical narrative method. RESULTS Thirty-nine studies met our inclusion criteria, 30 of which related to psychosocial needs, and the remainder examined psychosocial interventions. Four main themes were derived from our analysis of psychosocial needs literature, as follows: the need for (1) emotional support, (2) acceptance, (3) direction, (4) equality in healthcare. 2 main themes emerged from analysis of psychosocial intervention literature, namely: psychosocial (1) capability, (2) assessment. Despite the evidence that graft health is strongly associated with psychosocial wellbeing, findings revealed a significant lack of literature investigating how best to meet psychosocial needs. Trends were observed amongst intervention studies, namely interventions of novel and non-evidenced based design, with the aim of improving medication adherence through organisational strategies and education. However, literature regarding psychosocial needs showed non-adherence to therapies was not simply a result of disorganisation or lack of understanding, but rather, was founded on a recipient's idiosyncratic relationship with their prescribed therapies e.g., psychological, social or financial reasons for non-adherence. CONCLUSIONS Future research should be directed at investigating the efficacy of evidence-based interventions that empower the individual patient to overcome their specific barrier to an optimal relationship with their therapies.

Abstract
BACKGROUND Sex differences in kidney graft loss rates were reported in the United States. Whether these differences are present in other countries is unknown. METHODS We estimated the association between recipient sex and death-censored graft loss in patients of all ages recorded in the Scientific Registry of Transplant Recipients, Australia and New Zealand Dialysis and Transplant Registry, and Collaborative Transplant Study registries who received a first deceased donor kidney transplant (1988-2019). We used multivariable Cox regression models, accounting for the modifying effects of donor sex and recipient age, in each registry separately; results were combined using individual patient data meta-analysis. RESULTS We analyzed 438 585 patients. Young female patients 13-24 y old had the highest crude graft loss rates (female donor: 5.66; male donor: 5.50 per 100 person-years). Among young recipients of male donors, females showed higher graft loss risks than males (0-12 y: adjusted hazard ratio [aHR] 1.42, (95% confidence interval [CI], 1.17-1.73); 13-24 y: 1.24 (1.17-1.32); 25-44 y: 1.09 (1.06-1.13)). When the donor was female, there were no significant differences by recipient sex among those of age <45 y; however, the aHR for females was 0.93 (0.89-0.98) in 45-59 y-old and 0.89 (0.86-0.93) in ≥ 60 y-old recipients. Findings were similar for all 3 registries in most age intervals; statistically significant heterogeneity was seen only among 13-24-y-old recipients of a female donor (I2 = 71.5%, P = 0.03). CONCLUSIONS There is an association between recipient sex and kidney transplantation survival that is modified by recipient age and donor sex.

Abstract
Adult nephrologists often look after patients who have been diagnosed with kidney disease in childhood. This does present unique challenges to the adult nephrologist, who may be unfamiliar with the underlying cause of kidney disease as well as the complications of chronic kidney disease (CKD) that may have accumulated during childhood. This review discusses common causes of childhood CKD, in particular congenital anomalies of the kidney and urinary tract (CAKUT), autosomal dominant tubulointerstitial kidney disease (ADTKD), polycystic kidney disease, hereditary stone disease, nephrotic syndrome and atypical haemolytic uraemic syndrome. The long-term consequences of childhood CKD, such as the cardiovascular consequences, cognition and education as well as bone health, nutrition and growth are also discussed.

Abstract
Kidney transplantation is the best health option for patients with end-stage kidney disease. Ideally, a kidney transplant would last for the lifetime of each recipient. However, depending on the age of the recipient and details of the kidney transplant, there may be a need for a second, third, fourth, or even more kidney transplants. In this overview, the outcome of multiple kidney transplants for an individual is presented. Key issues include surgical approach and immunologic concerns. Included in the surgical approach is an analysis of transplant nephrectomy, with indications, timing, and immunologic impact. Allograft thrombosis, whether related to donor or recipient factors merits investigation to prevent it from happening again. Other posttransplant events such as rejection, viral illness (polyomavirus hominis type I), recurrent disease (focal segmental glomerulosclerosis), and posttransplant lymphoproliferative disease may lead to the need for retransplantation. The pediatric recipient is especially likely to need a subsequent kidney transplant. Finally, noncompliance/nonadherence can affect both adults and children. Innovative approaches may reduce the need for retransplantation in the future.

Abstract
Sex and gender often are used interchangeably, but are two distinct entities, with sex being the biological attribute and gender including the social, psychological, and cultural aspects of one's identity. Kidney transplantation has been proven to be the best treatment for end-stage kidney disease, improving both quality of life and life-expectancy for most patients. However, gender disparities in access to and outcomes of kidney transplantation remain despite the plethora of evidence showing the advantages of kidney transplantation to our patients. Data have shown that women are less likely to be waitlisted for a kidney transplant and to receive a deceased donor or a living donor kidney. On the other hand, women are more likely than men to become living kidney donors. Although some state the latter is the result of the female gender to nurture and care for loved ones, others believe this observation is because women often are incompatible with their spouse or child because pregnancy is a strong sensitizing event, which stems from the biological rather than the social differences between the sexes. Influence of sex and gender is not limited to access to kidney transplantation, but rather exist in other areas of transplant medicine, such as the difference observed in transplant outcomes between the sexes, variability in immunosuppression metabolism, and even in more contemporary areas such as recent data showing sex-based differences in outcomes of kidney transplant recipients with coronavirus disease-2019, with males having an increased incidence of acute kidney injury and death.

Abstract
BACKGROUND Many centers accept a minimum body weight of 10 kg as threshold for kidney transplantation (Tx) in children. As solid evidence for clinical outcomes in multinational studies is lacking, we evaluated practices and outcomes in European children weighing below 10 kg at Tx. METHODS Data were obtained from the European Society of Paediatric Nephrology/European Renal Association and European Dialysis and Transplant Association Registry on all children who started kidney replacement therapy at <2.5 y of age and received a Tx between 2000 and 2016. Weight at Tx was categorized (<10 versus ≥10 kg) and Cox regression analysis was used to evaluate its association with graft survival. RESULTS One hundred of the 601 children received a Tx below a weight of 10 kg during the study period. Primary renal disease groups were equal, but Tx <10 kg patients had lower pre-Tx weight gain per year (0.2 versus 2.1 kg; P < 0.001) and had a higher preemptive Tx rate (23% versus 7%; P < 0.001). No differences were found for posttransplant estimated glomerular filtration rates trajectories (P = 0.23). The graft failure risk was higher in Tx <10 kg patients at 1 y (graft survival: 90% versus 95%; hazard ratio, 3.84; 95% confidence interval, 1.24-11.84), but not at 5 y (hazard ratio, 1.71; 95% confidence interval, 0.68-4.30). CONCLUSIONS Despite a lower 1-y graft survival rate, graft function, and survival at 5 y were identical in Tx <10 kg patients when compared with Tx ≥10 kg patients. Our results suggest that early transplantation should be offered to a carefully selected group of patients weighing <10 kg.
