[PMID: 38216782 PMCID: PMC11199301 DOI: 10.1007/s00467-023-06232-1] [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: 05/28/2023] [Revised: 11/06/2023] [Accepted: 11/07/2023] [Indexed: 01/14/2024]
Abstract
BACKGROUND Over one thousand pediatric kidney transplant candidates are added to the waitlist annually, yet the prospective time spent waiting is unknown for many. Our study fills this gap by identifying variables that impact waitlist time and by creating an index to predict the likelihood of a pediatric candidate receiving a transplant within 1 year of listing. This index could be used to guide patient management by giving clinicians a potential timeline for each candidate's listing based on a unique combination of risk factors. METHODS A retrospective analysis of 3757 pediatric kidney transplant candidates from the 2014 to 2020 OPTN/UNOS database was performed. The data was randomly divided into a training set, comprising two-thirds of the data, and a testing set, comprising one-third of the data. From the training set, univariable and multivariable logistic regressions were used to identify significant predictive factors affecting wait times. A predictive index was created using variables significant in the multivariable analysis. The index's ability to predict likelihood of transplantation within 1 year of listing was validated using ROC analysis on the training set. Validation of the index using ROC analysis was repeated on the testing set. RESULTS A total of 10 variables were found to be significant. The five most significant variables include the following: blood group, B (OR 0.65); dialysis status (OR 3.67); kidney disease etiology, SLE (OR 0.38); and OPTN region, 5 (OR 0.54) and 6 (OR 0.46). ROC analysis of the index on the training set yielded a c-statistic of 0.71. ROC analysis of the index on the testing set yielded a c-statistic of 0.68. CONCLUSIONS This index is a modest prognostic model to assess time to pediatric kidney transplantation. It is intended as a supplementary tool to guide patient management by providing clinicians with an individualized prospective timeline for each candidate. Early identification of candidates with potential for prolonged waiting times may help encourage more living donation including paired donation chains.

Abstract
Transition to adult health care has become a mainstream focus in pediatric health care as a higher percentage of patients are surviving into adulthood. This study investigated the success of a structured educational transition program in improving pediatric heart transplant patients' overall medical knowledge, medication adherence, readiness to transition, as well as parental perceptions of their child's readiness to transition to aid in the successful transition to an adult heart transplant program. Patients underwent a structured transition program over 2 years that included a total of seven 2-hour educational sessions hosted quarterly. This study comprised of a retrospective review of 12 heart transplant patients between the ages of 16-22 years. Test results indicated a statistically significant increase in overall medical knowledge scores from presession assessment compared to post-session assessment. Participants remained confident in their ability to transition throughout the program. Further, a statistically significant decrease in participant non-adherence was observed, as percentage of calcineurin inhibitor levels determined to be out of range decreased over the course of the program. Results suggest that a structured transition program is effective in improving overall patient medical knowledge in relation to their heart transplant and enhancing patient medication adherence. To effectively facilitate transition, pediatric providers, caregivers, and patients must communicate to provide a purposeful planned transition experience from pediatric to adult health care.

Patient Prefer Adherence 2019; 13:705-719.

Abstract
Background: Medication adherence is a major concern in public health. It is fully established that immunosuppressive therapy (IT) and concomitant medications affect transplant outcomes in the pediatric population, showing interest in adherence to this therapy. The aim of the present review was to report on medication adherence in pediatric population post-transplantation. This will enable us to know the situation in this particular population. Methods: A literature search was performed using the MEDLINE database. Studies that were published from January 1999 to January 2016 in English language and which investigated medication adherence in pediatric transplantation were included. The type of organ and the methods used to assess medication adherence were studied. Results: A total of 281 records were identified, from which 34 studies were selected: 38% (n=13) on kidney transplantation, 32% (n=11) on liver transplantation, and 23% (n=10) on the transplantation of other organs. Medication adherence was found to be lower than 80% in two-thirds of the studies (64%), and varied from 22% to 97%. This wide range was explained in part by the important heterogeneity of assessment methods among studies. The methods used were objective, non-objective, or combined both types. Most studies did not fully describe the data collected: the time since transplantation, the period over which adherence was assessed, the population, the medications, and the threshold discriminating adherence and non-adherence. Conclusion: The present study found poor medication adherence in the pediatric population post-transplantation. There was a wide range of medication adherence, explained largely by the heterogeneity of assessment methods. Future studies must consider the characteristics of each methodology, but also the threshold defining adherence should be chosen on the basis of clinical outcomes, and describe all data collected to gain precision. To improve adherence in this population, it is essential to identify factors influencing medication (IT and concomitant medications) adherence.

Graft Growth and Podocyte Dedifferentiation in Donor-Recipient Size Mismatch Kidney Transplants. Transplant Direct 2017; 3:e210.

Abstract
Background Kidney transplantation is the treatment choice for patients with end-stage renal diseases. Because of good long-term outcome, pediatric kidney grafts are also accepted for transplantation in adult recipients despite a significant mismatch in body size and age between donor and recipient. These grafts show a remarkable ability of adaptation to the recipient body and increase in size in a very short period, presumably as an adaptation to hyperfiltration. Methods We investigated renal graft growth as well as glomerular proliferation and differentiation markers Kiel-67, paired box gene 2 and Wilms tumor protein (WT1) expression in control biopsies from different transplant constellations: infant donor for infant recipient, infant donor for child recipient, infant donor for adult recipient, child donor for child recipient, child donor for adult recipient, and adult donor for an adult recipient. Results We detected a significant increase in kidney graft size after transplantation in all conditions with a body size mismatch, which was most prominent when an infant donated for a child. Podocyte WT1 expression was comparable in different transplant conditions, whereas a significant increase in WT1 expression could be detected in parietal epithelial cells, when a kidney graft from a child was transplanted into an adult. In kidney grafts that were relatively small for the recipients, we could detect reexpression of podocyte paired box gene 2. Moreover, the proliferation marker Kiel-67 was expressed in glomerular cells in grafts that increased in size after transplantation. Conclusions Kidney grafts rapidly adapt to the recipient size after transplantation if they are transplanted in a body size mismatch constellation. The increase in transplant size is accompanied by an upregulation of proliferation and dedifferentiation markers in podocytes. The different examined conditions exclude hormonal factors as the key trigger for this growth so that most likely hyperfiltration is the key trigger inducing the rapid growth response.

Abstract
This study evaluated multidimensional QoL after renal transplant to find the physical, psychosocial, and economic issues after pediatric transplant. Sixty-two patients under the age of 18 at the time of assessment were asked to complete WHOQOL questionnaires. Assessment of behavioral, emotional status of child, problems of parents, and SEC of family were also performed. The beneficial effect of transplantation was observed across all domains of QoL (physical, psychological, social, environmental, and overall QoL). The greatest change was observed in QoL domains that dealt with overall satisfaction (81.28±15.76 vs 45.32±10.98; P<.0001). The domain dealing with environmental factors showed the least variation after transplantation (65.58±17.45 vs 51.34±17.81; P<.0001). Feelings of happiness and peer group socialization were reported in 81% and 69% of patients, respectively. There was no marital disharmony in 52% of families. However, SEC deteriorated in 16% of families and 59% of the families availed financial assistance. Sixty-nine percent of children had not attended school after one year of transplantation, but return to school after transplant was reduced to 8% at 5 years. Pre- and post-transplant social and psychological support may help these patients and their families adjust in society and have a positive outlook for their future.

Abstract
The transfer of renal transplant patients from pediatric to adult care is a crucial step with a high risk of subsequent graft loss. Therefore, the transition should be a thoroughly planned, well-designed and multidisciplinary process focused on the individual patient. Our pediatric nephrology department introduced a structured step-by-step transition program supported by a multidisciplinary team of health professionals. The purpose of our study was to determine the effects of the transition program on eGFR and number of ARs in comparison to a group without a transition program at one and three yr after transfer. We conducted a single-center retrospective cohort study of renal transplant patients prior to and after the introduction of the transition program. Multiple regression analysis revealed a significantly lower decline of eGFR in the group with transition program (-11.3 ± 44 mL/min/1.73 m(2) ) compared to the group without transition program (-28.4 ± 33 mL/min/1.73 m(2) ) at three yr after transfer. The number of AR episodes significantly decreased from 34.6% in the group without transition program to 9.1% in the group with transition program. The standardized multilevel transition program seems to have significant positive effects on eGFR and number of AR episodes in renal transplant patients.

Abstract
RTx is best treatment for children with ESRD. Data scarcity on DDRTx outcome in children prompted us to review our experience. This study was undertaken to evaluate patient/graft survival, function vis-a-vis SCr, rejection episodes, and mortality in DDRTx performed in 37 children between 1998 and 2011. The most common recipient diseases leading to ESRD were congenital anomalies of kidney and urinary tract (48.6%) and chronic glomerulonephritis (18.9%). Mean recipient age was 13.8 ± 3.1 yr; 67.5% (n = 25) were men. Mean donor age was 38.8 ± 18.6 yr; 48.5% (n = 18) were men. Mean dialysis duration pre-transplantation was 15.5 ± 3.5 months. All recipients received r-ATG, and triple immunosuppression. Over a mean follow-up of 3.93 ± 3.5 yr, patient and graft survival rates were 72.9% (n = 27) and 83.7% (n = 31), respectively, with a mean SCr of 1.1 mg/dL; 21.6% (n = 8) of patients had acute rejection episodes; 24.3% (n = 9) of patients had DGF. A total of 27% (n = 10) patients died, mainly owing to infections (n = 6) and cardiovascular disease (n = 3). DDRTx is a viable option for children and achieves acceptable graft function with patient/graft survival over long-term follow-up, encouraging use of this approach.

Abstract
Nurse practitioners are a critical part of the transplant team, enhancing the quality of patient care with their knowledge and skill with respect to disease-specific populations of patients. Adolescent transplant recipients are a vulnerable population and require specific considerations. Nurse practitioners can successfully tailor care to the adolescent developmental stages in order to promote quality of life, adherence to the medical regimen, and successful transition to adult transplant centers and to minimize risk-taking behaviors. Teamwork between the patient's family and the entire transplant team is important to optimize not only the patient's health but also to ensure quality of life after transplant. Adolescents can be especially challenging after transplant, given their complex and evolving psychosocial and cognitive development. Nurse practitioners are in a unique position to be central in adolescents' successful adaptation to their medical condition. Facilitating identification and management of medication-related side effects, awareness of emotional health and quality of life, adherence to the medical regimen, and eventual transition to adult caregivers all remain critically important steps in care that are ideally suited for advance practice leadership.

Abstract
Pediatric solid-organ transplantation is an increasingly successful treatment for solid-organ failure. With dramatic improvements in patient survival rates over the last several decades, there has been a corresponding emergence of complications attributable to pretransplant factors, transplantation itself, and the management of transplantation with effective immunosuppression. The predominant solid-organ transplantation sequelae are medical and psychosocial. These sequelae have a substantial effect on transition to adult care; as such, hurdles to successful transition of care arise from the patients, their families, and pediatric and adult health care providers. Crucial to successful transitioning is the ongoing development of a sense of autonomy and responsibility for one's own care. In this article we address the barriers to transitioning that occur with long-term survival in pediatric solid-organ transplantation. Although a particular transitioning model is not promoted, practical tools and strategies that contribute to successful transitioning of pediatric patients who have received a transplant are suggested.

Abstract
LaR Pediatric solid-organ transplantation is an increasingly successful treatment for organ failure. Five- and 10-yr patient survival rates have dramatically improved over the last couple of decades, and currently, over 80% of pediatric patients survive into adolescence and young adulthood. Waiting list mortality has been a concern for liver, heart, and intestinal transplantation, illustrating the importance of transplant as a life-saving therapy. Unfortunately, the success of pediatric transplantation comes at the cost of long-term or late complications that arise as a result of allograft rejection or injury, immunosuppression-related morbidity, or both. As transplant recipients enter adolescence treatment, non-adherence becomes a significant issue, and the medical and psychosocial impacts transition to adulthood not only with regard to healthcare but also in terms of functional outcomes, economic potential, and overall QoL. This review addresses the clinical and psychosocial challenges encountered by pediatric transplant recipients in the current era. A better understanding of pediatric transplant outcomes and adult morbidity and mortality requires further ongoing assessment.

Abstract
As most prior reviews on NA focus on adult transplant patients, there is a need for a comprehensive overview on adherence to the immunosuppressive regimen in pediatric kidney transplant patients. This systematic review searched for English-language papers (1990-2008) addressing the prevalence of NA to the immunosuppressive regimen, its consequences, determinants, and interventions in pediatric kidney transplant patients (< age 21 yr). We found 36 papers, showing a prevalence of NA (weighted mean) of 31.8% with adolescents being more at risk compared to younger patients. About 44% of all graft losses and 23% of late acute rejection episodes are associated with NA. Most studies investigated socio-economic, condition-related or treatment-related determinants. Only one educational intervention has been tested but yielded inconclusive results. NA to the immunosuppressive regimen is prevalent with serious clinical consequences in pediatric kidney transplant patients, but the economic consequences have not yet been explored. More studies on determinants of NA are needed. The literature currently lacks fully powered RCTs testing adherence-enhancing interventions. The results of this systematic review identify the gaps in the present evidence-based information regarding NA and can be used as a tool to pursue future adherence research in pediatric populations.

Abstract
Long-term survival after pediatric solid organ transplantation is now the rule rather than the exception for increasing numbers of children with end-stage organ diseases. While transplantation restores organ function it does not necessarily return one to a normal life. Therefore, it is prudent to focus on assessment of not only traditional biologic outcomes but also the quality life for these children and their families. This article gives a brief overview of current definitions, conceptualizations, approaches to measurement of, and unique considerations in the evaluation of quality of life in children who have undergone solid organ transplant. Current understanding of quality of life in children who have undergone solid organ transplantation is reviewed, followed by limitations of current knowledge. Clinical implications are discussed and future research directions suggested.

Abstract
OBJECTIVES To examine medication adherence trajectories posttransplantation and the association between adherence trajectories and self-reported internalizing symptoms in a pediatric population. METHODS Multilevel modeling was used to examine internalizing symptoms and longitudinal medication adherence, as assessed by electronic monitoring, among 55 children and adolescents who received liver or kidney transplantation. RESULTS Medication adherence generally declined over the study assessment window, and higher levels of anxiety were associated with higher and more stable patterns of medication adherence. CONCLUSIONS Anxiety may be an important factor to consider when assessing and intervening with posttransplantation medication adherence. Future research should consider the potential reactivity effects of adherence monitoring, as well as individual and family behaviors associated with anxiety that may influence adherence.

Abstract
Kidney transplantation is an optimal therapy for pediatric patients with end-stage kidney disease. This pilot study sought to examine multidimensional QOL outcomes after kidney transplant using VAQOL and General Health, the PedsQL 4.0, PedsQL End Stage Renal Disease Module, and Impact on Family Module. Sample included 12 adolescents aged 13-18 yr and their parent; three children aged eight to 12 yr and their parent; and six parents of children aged two to seven yr. All were 73 months post transplant. The median age at transplant was 9.3 yr and median time since transplant was 3.2 yr. VAQOL mean was 7.7/10 (child report) and 7.3/10 (parent report); the mean general health was 7.4/10. High levels of fatigue (> or =5/10) were reported in 43%. PedsQL subscale mean values were lower than healthy reference scores. PedsQL Renal Module demonstrated great concern with physical appearance and physical symptoms (thirst and headaches), difficulty with peer and family interaction, and school disruption. Low scores on parental emotional function depict the negative impact of transplant on family functioning. Discordance exists between child and parental reports of QOL. Prospective studies are needed to explore multidimensional QOL to improve long-term outcomes after pediatric kidney transplant.

Abstract
BACKGROUND Adherence to the medical regimen after pediatric organ transplantation is important for maximizing good clinical outcomes. However, the literature provides inconsistent evidence regarding prevalence and risk factors for nonadherence posttransplant. METHODS A total of 61 studies (30 kidney, 18 liver, 8 heart, 2 lung/heart-lung, and 3 with mixed recipient samples) were included in a meta-analysis. Average rates of nonadherence to six areas of the regimen, and correlations of potential risk factors with nonadherence, were calculated. RESULTS Across all types of transplantation, nonadherence to clinic appointments and tests was most prevalent, at 12.9 cases per 100 patients per year (PPY). The immunosuppression nonadherence rate was six cases per 100 PPY. Nonadherence to substance use restrictions, diet, exercise, and other healthcare requirements ranged from 0.6 to 8 cases per 100 PPY. Only the rate of nonadherence to clinic appointments and tests varied by transplant type: heart recipients had the lowest rate (4.6 cases per 100 PPY vs. 12.7-18.8 cases per 100 PPY in other recipients). Older age of the child, family functioning (greater parental distress and lower family cohesion), and the child's psychological status (poorer behavioral functioning and greater distress) were among the psychosocial characteristics significantly correlated with poorer adherence. These correlations were small to modest in size (r=0.12-0.18). CONCLUSIONS These nonadherence rates provide benchmarks for clinicians to use to estimate patient risk. The identified psychosocial correlates of nonadherence are potential targets for intervention. Future studies should focus on improving the prediction of nonadherence risk and on testing interventions to reduce risk.

Abstract
Medication adherence is essential for the survival of kidney grafts, however, the complexity of the medication-taking regimen makes adherence difficult. Little is known about barriers to medication-taking and strategies to foster medication-taking. This cross-sectional study involved semi-structured interviews with 82 kidney transplant recipients approximately 2 months post-transplant on medication-related adherence, barriers to medication-taking, and strategies to foster medication-taking. Although self-reported adherence was high (88%), qualitative analysis revealed that half of the patients (49%) reported experiencing at least one barrier to medication-taking. The most common barriers were: not remembering to refill prescriptions (13%), changes to medication prescriptions or dosages (13%), being busy (10%), forgetting to bring medicines with them (10%), and being away from home (10%). The most common strategies to foster medication-taking were: maintaining a schedule of medication-taking (60%), organizing pills using pillboxes, baggies, cups (42%), bringing medicines with them (34%), organizing pills according to routine times (32%), and relying on other people to remind them (26%). Understanding the range of barriers to adherence and strategies kidney recipients devised to promote medication-taking may help transplant clinicians to better educate transplant recipients about appropriate medication-taking, mitigate the risk of medication nonadherence-related rejection, and may help inform patient-centered interventions to improve medication adherence.

Abstract
Steroid withdrawal (SW) after paediatric renal transplantation (RTPL) is controversial. Selective late SW has been performed in our unit since 1995. The safety and effects of SW were analysed retrospectively in 47 patients undergoing RTPL between 1995 and 2004. Initial immunosuppression consisted of cyclosporine A, azathioprine or mycophenolate mofetil and steroids. Criteria for SW were: (1) stable renal function, (2) time interval after RTPL > or = 1 year, (3) no rejection or time interval after last rejection > or = 1 year and (4) good compliance. SW was performed in 30 patients at an age of 13.5 years (range 4.5-18.5) and 2.2 years (range 1-6.6) after RTPL. After SW, one patient experienced a steroid-sensitive rejection. Follow-up after SW (1.3 year; range 0.25-7.5) showed maintained renal function: glomerular filtration rate at SW and currently was 82 (65-128) and 82 (42-115) ml/min per 1.73 m(2), respectively. The number of patients on antihypertensive treatment did not significantly change (at SW: n = 15; currently: n = 11). Height and body mass index (BMI) remained stable: Median standard deviation score (SDS) for height/BMI at SW and currently was -1.1/0.2 and -0.8/0.1, respectively. Selective late SW was safe regarding renal function and had no significant effect on blood pressure and growth.

Abstract
This study investigated the advantages and challenges of using Medication Electronic Monitoring System (MEMS) technology to examine adherence among pediatric kidney transplant patients. Twenty-nine patients participated in the study, with a mean age of 14.03 yr (SD = 3.34, range 8-19 yr). Patients were given a MEMS bottle and cap to be used with their primary immunosuppressant medication over a three-month period. Issues related to study eligibility, recruitment, and participant maintenance were recorded. Patients completed the Debriefing Form regarding their experiences with the MEMS. Many younger patients were on liquid medications affecting the feasibility of this technology across ages. Acceptance of this technology proved difficult, as many patients either declined upfront or dropped out because they did not want to use the MEMS. Of the final sample, 41% found transferring medication into the MEMS bottle difficult and 27.2% reported that the MEMS was a burden and/or difficult to transport. Another 22% of the patients reported that using the MEMS changed their routine, and 10.2% worried about missing their medications. Pediatric transplant centers should be cautious about solely relying on MEMS to examine adherence until more research is conducted on the feasibility, acceptance, and utility of this technology.

Abstract
Renal transplantation is a therapeutic goal for children with advanced chronic kidney disease. There are many causes of renal dysfunction in children with allografts--the transplanted kidney can develop a variety of morphologic alterations leading to dysfunction. Evaluation of the kidney biopsy is one of the best methods of determining the cause of graft dysfunction. Rejection is a major cause of renal allograft failure in children. The morphologic hallmarks of acute antibody-mediated and cell-mediated rejection and chronic allograft nephropathy have been codified in classification strategies that are useful in adults and children. Viral infection and Epstein-Barr virus-driven posttransplant lymphoproliferative disease also occur in the pediatric transplanted kidney. Drug toxicity from immunosuppressive agents also causes characteristic morphologic alterations in the renal allograft. As the survival of pediatric heart and liver transplant patients improves, the incidence of immunosuppression therapy-related disease in the native kidney in these patients will likely become more important clinically. In addition to renal lesions related to the allograft state, glomerular disease can recur or occur de novo in renal allografts. Here, we describe the pathology of the more common morphologic lesions in kidneys of children with a renal allograft.

Abstract
BACKGROUND Renal transplantation is the most optimal way to manage children with end-stage renal disease. Despite its benefits, pediatric renal transplantation is a challenge for several transplantation centers in terms of achieving a satisfactory outcome. We sought to compare the long-term outcome of pediatric versus adult recipients who underwent renal transplantation. METHOD We examined, 2631 recipients of a first kidney from a living donor between 1982 and 2002. The two groups were matched for immunosuppressive therapy and number of HLA mismatches. The patients were divided into a pediatric (n=301; age <or= 18 years) and an adult group (n=2330; age > 18 years) to compare 5-year patient and graft survivals. RESULTS The mean ages of the pediatric and adult groups were 40 +/- 13 and 14 +/- 13 years, respectively. The 5-year graft survival was lower among the pediatric versus the adult group (56% vs 68%; P=.015) with no difference in patient survival (88% vs 86%; P>.05). CONCLUSION The poorer graft survival in pediatric transplantation may be due to the nature of pediatric transplantation, in terms of inconsistent adherence to medication regimens, worse side effects of medications, higher rate of graft rejection due to recurrent disease, and more intense immunoreactivity of children.

Abstract
BACKGROUND Despite the impact of medical regimen nonadherence on health outcomes after organ transplantation, there is mixed and conflicting evidence regarding the prevalence and predictors of posttransplant nonadherence. Clinicians require precise information on nonadherence rates in order to evaluate patients' risks for this problem. METHODS A total of 147 studies of kidney, heart, liver, pancreas/kidney-pancreas, or lung/heart-lung recipients published between 1981 and 2005 were included in a meta-analysis. Average nonadherence rates were calculated for 10 areas of the medical regimen. Correlations between nonadherence and patient psychosocial risk factors were examined. RESULTS Across all types of transplantation, average nonadherence rates ranged from 1 to 4 cases per 100 patients per year (PPY) for substance use (tobacco, alcohol, illicit drugs), to 19 to 25 cases per 100 PPY for nonadherence to immunosuppressants, diet, exercise, and other healthcare requirements. Rates varied significantly by transplant type in two areas: immunosuppressant nonadherence was highest in kidney recipients (36 cases per 100 PPY vs. 7 to 15 cases in other recipients). Failure to exercise was highest in heart recipients (34 cases per 100 PPY vs. 9 to 22 cases in other recipients). Demographics, social support, and perceived health showed little correlation with nonadherence. Pretransplant substance use predicted posttransplant use. CONCLUSIONS The estimated nonadherence rates, overall and by transplant type, allow clinicians to gauge patient risk and target resources accordingly. Nonadherence rates in some areas--including immunosuppressant use--appear unacceptably high. Weak correlations of most patient psychosocial factors with nonadherence suggest that attention should focus on other classes of variables (e.g., provider-related and systems-level factors), which may be more influential.

Abstract
Given the rise in chronic kidney disease (CKD) in both children and adults, CKD has recently been targeted as a public health priority. Childhood onset kidney disease is generally a noncurable and progressive condition that leads to kidney failure by early adulthood. Fortunately, improved identification of kidney problems allows for early intervention, which is thought to slow progression toward end-stage renal disease. In addition, medical interventions for pediatric end-stage renal disease have also improved, allowing children to take advantage of lifesaving renal replacement treatments such as dialysis and kidney transplantation. In spite of improvements in identification and treatment, CKD causes both direct and indirect insults to a variety of organ systems. This paper reviews recently published studies pertaining to the neurocognitive and psychosocial impact of CKD on children of various ages and at various stages of kidney failure. Specific attention is focused on summarizing peer reviewed research that describes associations between kidney functioning and cognitive functioning, language acquisition, visual spatial abilities, memory, and executive functioning. In addition, peer reviewed research describing psychosocial outcomes associated with CKD related to academic achievement, social-behavioral functioning, and quality of life are summarized. The authors also identified disease-specific factors that likely mediate neurocognitive outcomes (e.g., anemia, hypertension, cardiovascular) and endorse the importance of continued interdisciplinary research collaborations that will provide a better understanding of the mechanisms responsible for improved neurocognitive functioning after transplantation. The authors conclude this review by describing a multicenter, prospective, longitudinal, National Institutes of Health funded study that is currently examining the developmental outcomes of children with mild to moderate CKD. The authors speculate that the Chronic Kidney Disease in Children Prospective Cohort Study (CKiD) findings will provide additional evidence-based guidance for clinicians and researchers working with children and adolescents with deteriorating kidney function to improve medical and developmental outcomes.
