Zhang J, Zhang A. Association between serum 25-hydroxyvitamin D3 level and cognitive impairment in older chronic kidney disease patients. Sci Rep 2024; 14:12403. [PMID: 38811765 PMCID: PMC11137016 DOI: 10.1038/s41598-024-63350-y] [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: 09/11/2023] [Accepted: 05/28/2024] [Indexed: 05/31/2024] Open
Abstract
This study aims to examine whether hypovitaminosis D was associated with cognitive impairment among chronic kidney patients with different level of albuminuria. This population-based cross-sectional study was conducted on elderly (over 60 years old) with urine albumin to creatinine ratio (UACR) ≥ 30 mg/g from 2011 to 2014 in the US National Health and Nutrition Examination Survey (NHANES). Cognitive function was assessed by the Consortium to Establish a Registry for Alzheimer's Disease Word List Learning (CERAD). Subjects were divided into 2 groups according to the absence or presence of cognitive impairment and a propensity score matching (PSM) was further conducted. The association was assessed with Spearman correlation and logistic regression analysis. The positive association of 25-hydroxyvitamin D3 (25(OH)D3) and cognitive score was presented. PSM analysis revealed that a higher level of 25(OH)D3 correlated to a better cognitive function in CKD patients with albuminuria, especially in patients with 30 mg/g ≤ UACR < 300 mg/g. This study indicated that a low 25(OH)D3 level was associated with poor cognitive performance, especially in patients with microalbuminuria. Thus, early diagnosis of vitamin D insufficiency and an effective intervention might be a useful therapeutic strategy to prevent cognitive decline in patients with the progression of renal dysfunction.

Transition of care: lessons from the Standardizing Care to Improve Outcomes in Pediatric End Stage Renal Disease (SCOPE) dialysis collaborative. Pediatr Nephrol 2024; 39:1551-1557. [PMID: 38085355 DOI: 10.1007/s00467-023-06244-x] [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: 09/14/2023] [Revised: 11/23/2023] [Accepted: 11/24/2023] [Indexed: 03/16/2024]
Abstract
BACKGROUND Acknowledging the importance of preparing the pediatric dialysis patient for successful transfer to adult providers, centers from the Standardizing Care to Improve Outcomes in Pediatric End Stage Renal Disease (SCOPE) Dialysis Collaborative developed transition tools and performed iterative implementation of a transition of care (TOC) program to gain real-life insight into drivers and barriers towards implementation of a transition program for patients receiving dialysis. METHODS A TOC innovation workgroup was developed in 2019 from within SCOPE Collaborative that developed nine educational modules, along with introductory letter and assessment tool to be utilized by SCOPE centers. A 4-month pilot implementation study among six centers of varying patient population (age ≥ 11 years) was performed. TOC tools were further refined, and broader implementation within the collaborative was performed. Interim assessment of TOC tool utilization and implementation success was performed among 11 centers, as a foundation towards broader discussion regarding process, barriers, and success towards TOC implementation among 26 centers. RESULTS Transition champion was a key driver of successful implementation, and lack of institutional support and collaboration with adult dialysis centers were important barriers towards sustainability. COVID pandemic and increased staff turnover affected longer term implementation of TOC program. CONCLUSIONS Successful transition and transfer of adolescents/young adults with kidney failure on dialysis remains a challenge. This study represents the experience of the largest cohort of pediatric dialysis centers, with diversity in population size and geography, towards development and implementation of a TOC program. This adds to the resources available to assist centers towards transition and transfer, with particular focus on transitioning patients on dialysis.

[PMID: 38707834 PMCID: PMC11068961 DOI: 10.1016/j.ekir.2024.01.042] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/02/2023] [Revised: 12/12/2023] [Accepted: 01/22/2024] [Indexed: 05/07/2024] Open
Abstract
Children and adolescents in families of lower socioeconomic position (SEP) experience an inequitable burden of reduced access to healthcare and poorer health. For children living with chronic kidney disease (CKD), disadvantaged SEP may exacerbate their considerable disease burden. Across the life-course, CKD may also compromise the SEP of families and young people, leading to accumulating health and socioeconomic disadvantage. This narrative review summarizes the current evidence on relationships of SEP with kidney care and health among children and adolescents with CKD from a life-course approach, including impacts of family SEP on kidney care and health, and bidirectional impacts of CKD on SEP. It highlights relevant conceptual models from social epidemiology, current evidence, clinical and policy implications, and provides directions for future research. Reflecting the balance of available evidence, we focus primarily on high-income countries (HICs), with an overview of key issues in low- and middle-income countries (LMICs). Overall, a growing body of evidence indicates sobering socioeconomic inequities in health and kidney care among children and adolescents with CKD, and adverse socioeconomic impacts of CKD. Dedicated efforts to tackle inequities are critical to ensuring that all young people with CKD have the opportunity to live long and flourishing lives. To prevent accumulating disadvantage, the global nephrology community must advocate for local government action on upstream social determinants of health; and adopt a life-course approach to kidney care that proactively identifies and addresses unmet social needs, targets intervening factors between SEP and health, and minimizes adverse socioeconomic outcomes across financial, educational and vocational domains.

Abstract
Recombinant human growth hormone therapy, which was introduced in the 1980s, is now routine for children with advanced chronic kidney disease (CKD) who are exhibiting growth impairment. Growth hormone usage remains variable across different centers, with some showing low uptake. Much of the focus on growth hormone supplementation has been on increasing height because of social and psychological effects of short stature. There are, however, numerous other changes that occur in CKD that have not received as much attention but are biologically important for pediatric growth and development. This article reviews the current knowledge about the multisystem effects of growth hormone therapy in pediatric patients with CKD and highlights areas where additional clinical research is needed. We also included clinical data on children and adults who had received growth hormone for other indications apart from CKD. Ultimately, having robust clinical studies which examine these effects will allow children and their families to make more informed decisions about this therapy.

[Formula: see text] The multifaceted role of neuropsychology in pediatric solid organ transplant: preliminary guidelines and strategies for clinical practice. Child Neuropsychol 2024; 30:503-537. [PMID: 37291962 DOI: 10.1080/09297049.2023.2221759] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/23/2022] [Accepted: 05/31/2023] [Indexed: 06/10/2023]
Abstract
The incidence of pediatric solid organ transplantation (SOT) has increased in recent decades due to medical and surgical advances as well as improvements in organ procurement. Survival rates for pediatric kidney, liver, and heart transplantation are above 85% but patients continue to experience complex healthcare needs over their lifetime. Long-term developmental and neuropsychological sequelae are becoming increasingly recognized in this population, although preliminary work is limited and deserves further attention. Neuropsychological weaknesses are often present prior to transplantation and may be related to underlying congenital conditions as well as downstream impact of the indicating organ dysfunction on the central nervous system. Neuropsychological difficulties pose risk for functional complications, including disruption to adaptive skill development, social-emotional functioning, quality of life, and transition to adulthood. The impact of cognitive dysfunction on health management activities (e.g., medication adherence, medical decision-making) is also an important consideration given these patients' lifelong medical needs. The primary aim of this paper is to provide preliminary guidelines and clinical strategies for assessment of neuropsychological outcomes across SOT populations for pediatric neuropsychologists and the multidisciplinary medical team, including detailing unique and shared etiologies and risk factors for impairment across organ types, and functional implications. Recommendations for clinical neuropsychological monitoring as well as multidisciplinary collaboration within pediatric SOT teams are also provided.

Abstract
The mental health of youth with chronic kidney disease (CKD) has been increasingly recognized as an area of clinical need. The development of mental health concerns is influenced by a range of physiological, psychological, and environmental factors. Some of these factors are common across child development, but some are more unique to youth with CKD. Mental health concerns are associated with increased risk for a range of poor medical outcomes (e.g., adherence, risk of transplant rejection) and quality of life concerns. In this educational review, we discuss the current evidence base regarding the development of mental health concerns in youth with CKD. The review covers multiple domains including mood and anxiety disorders, traumatic stress, and neurodevelopmental disorders. Estimated prevalence and hypothesized risk factors are outlined, and the potential impact of mental health on medical care and functional outcomes are reviewed. Finally, we introduce options for intervention to support positive mental health and offer recommendations for building access to mental health care and improving the mental health education/training of medical professionals.

Abstract
BACKGROUND Within the pediatric population, a positive self-concept is associated with better academic achievement. Children with chronic kidney disease (CKD) are at risk for lower quality of life and academic underachievement. Little is known about self-concept among children with CKD and how self-concept influences academic achievement. The objectives of the present study were to (1) describe patient-reported self-concept among children with CKD and (2) evaluate the relationship between self-concept and academic performance. METHODS This cross-sectional study included 23 children, aged 6-16 years, with mild to moderate CKD (cause of disease due to congenital anomalies of the kidney and urinary tract) and 26 age-matched comparators. Participants completed the Self-Description Questionnaire (SDQ) and the Wide Range Achievement Test (WRAT-4). Linear regression models were used to evaluate self-concept as a predictor of academic achievement in the CKD cohort. RESULTS Self-concept ratings were comparable between children with CKD and non-CKD comparators; however, academic achievement trended lower for the CKD patients on measures of arithmetic (estimate = - 0.278, 95% confidence interval (CI) [- 0.530: - 0.026], t(45) = - 1.99, p = 0.053). All of the SDQ domains predicted WRAT-4 arithmetic performance, such that higher scores on the SDQ were associated with higher scores in mathematics. Kidney function did not have an effect on the relationship between self-concept and academic achievement. CONCLUSIONS Despite the presence of a chronic disease, children with CKD endorse a positive self-concept. Positive self-concept may predict academic success in this population.

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.

Associations of exposure to bisphenol A and its substitutes with neurodevelopmental outcomes among infants at 12 months of age: A cross-sectional study. CHEMOSPHERE 2023; 341:139973.

Abstract
BACKGROUND Bisphenol A (BPA) exposure has been linked to adverse childhood neurodevelopment, but little is known about whether BPA substitutes exposures are also related to childhood neurodevelopment. OBJECTIVES To investigate the associations of exposure to BPA and its substitutes with infant neurodevelopment at 12 months. METHODS A total of 420 infants at 12 months were included from the Laizhou Wan (Bay) Birth Cohort in Shandong, China. Urinary concentrations of BPA and its substitutes including bisphenol S (BPS), bisphenol B (BPB), bisphenol AF (BPAF), bisphenol AP (BPAP), bisphenol P (BPP) and bisphenol Z (BPZ) were measured. Developmental quotient (DQ) scores based on the Gesell Development Schedules (GDS) were used to evaluate infant neurodevelopment. The multivariable linear regression and weighted quantile sum (WQS) regression were applied to estimate the associations of exposure to individual bisphenols and their mixtures with DQ scores, respectively. Sex-stratified analyses were also performed. RESULTS BPA was detected in most infants (89.05%) and had the highest median concentration (0.709 ng/mL) among all bisphenols. BPA substitutes except BPZ were ubiquitous in infants' urine samples (>70%), and BPS showed the highest median concentration (0.064 ng/mL) followed by BPAP (0.036 ng/mL), BPAF (0.028 ng/mL), BPP (0.015 ng/mL) and BPB (0.013 ng/mL). In multivariable linear regression, only BPAF exposure was inversely associated with social DQ scores among all infants (β = -0.334; 95% CI: -0.650, -0.019). After sex stratification, this inverse association was significant in girls (β = -0.605; 95% CI: -1.030, -0.180). Besides, BPA exposure was negatively related to gross motor DQ scores in boys (β = -1.061; 95% CI: -2.078, -0.045). WQS analyses confirmed these results. CONCLUSIONS Our study suggests that bisphenol exposure during infancy may be associated with poor infant neurodevelopment, and BPAF as a commonly used BPA substitute contributing the most to this adverse association deserves more attention.

Abstract
Key Points This study evaluates educational and employment outcomes in patients with pediatric kidney disease and assesses predictors of educational attainment and employment in young adulthood. Despite high rates of high school graduation, nearly 20% of patients with CKD are unemployed or receiving disability at long-term follow-up. Background Pediatric patients with CKD are at risk for neurocognitive deficits and academic underachievement. This population may be at risk for lower educational attainment and higher rates of unemployment; however, published data have focused on patients with advanced CKD and exist in isolation from assessment of neurocognition and kidney function. Methods Data from the CKD in Children (CKiD) cohort study were used to characterize educational attainment and employment status in young adults with CKD. We used ratings of executive function as a predictor of future educational attainment and employment status. Linear regression models predicted the highest grade level completed. Logistic regression models predicted unemployment. Results A total of 296 CKiD participants aged 18 years or older had available educational data. In total, 220 of 296 had employment data. By age 22 years, 97% had completed high school and 48% completed 2+ years of college. Among those reporting employment status, 58% were part-time or full-time employed, 22% were nonworking students, and 20% were unemployed and/or receiving disability. In adjusted models, lower kidney function (P = 0.02), worse executive function (P = 0.02), and poor performance on achievement testing (P = 0.004) predicted lower grade level completed relative to expectation for age. Conclusions CKiD study patients appear to have a better high school graduation rates (97%) than the adjusted national high school graduation rate (86%). Conversely, roughly 20% of participants were unemployed or receiving disability at study follow-up. Tailored interventions may benefit patients with CKD with lower kidney function and/or executive function deficits to optimize educational/employment outcomes in adulthood.

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.

Pediatr Transplant 2023; 27:e14505.

Abstract
BACKGROUND Pediatric chronic kidney disease (CKD) patients are at risk for cognitive deficits with worsening disease progression. Limited, existing cross-sectional studies suggest that cognitive deficits may improve following kidney transplantation. We sought to assess cognitive performance in relationship to kidney transplantation and kidney-specific medical variables in a sample of pediatric kidney transplant patients who provided cross-sectional and longitudinal observations. METHODS A retrospective chart review was conducted in patients who completed pre- and/or post-transplant neurocognitive testing at the University of Iowa from 2015-2021. Cognitive outcomes were investigated with developmentally appropriate, standardized measures. Mixed linear models estimated the impact of transplant status on cognitive function (z-scores). Subsequent post-hoc t-tests on change scores were limited to patients who had provided pre- and post-transplant assessments. RESULTS Thirty eight patients underwent cognitive assessments: 10 had both pre- and post-transplant cognitive assessments, 11 had pre-transplant assessments only, and 17 had post-transplant data only. Post-transplant status was associated with significantly lower full-scale IQ and slower processing speed compared to pre-transplant status (estimate = -0.32, 95% confidence interval [CI] = -0.52: -0.12; estimate = -0.86, CI = -1.17: -0.55, respectively). Post-hoc analyses confirmed results from the mixed models (FSIQ change score = -0.34, 95% CI = -0.56: -0.12; processing speed change score = -0.98, CI = -1.28: -0.68). Finally, being ≥80 months old at transplant was associated with substantially lower FSIQ compared to being <80 months (estimate = -1.25, 95% CI = -1.94: -0.56). CONCLUSIONS Our results highlight the importance of monitoring cognitive function following pediatric kidney transplant and identify older transplant age as a risk factor for cognitive deficits.

Abstract
BACKGROUND Children with chronic kidney disease (CKD) are at risk for cognitive dysfunction. The aim of this study was to investigate associations between executive functions (EF), anemia, and iron deficiency. METHODS A total of 688 children > 6 years of age enrolled in the Chronic Kidney Disease in Children (CKiD) study who underwent evaluation for EF were included. Hemoglobin (Hgb) was characterized as low (1st-5th percentile) or very low (< 1st percentile) compared to normative values for age, sex, and race irrespective of erythropoiesis-stimulating agent (ESA) usage. Longitudinal analysis was conducted using consecutive visit pairs, with anemia status defined as new onset, resolved, or persistent. Linear mixed models with random intercept were used and adjusted for key covariates. RESULTS Anemia was present in 41% of children, and median Hgb was 11.8 gm/dl. New onset anemia was associated with lower digit span total score (- 0.75, 95% CI - 1.36, - 0.15, p = 0.01). Persistent anemia was associated with lower scores on color-word inhibition/switching (β = - 0.98; 95% CI - 1.78, - 0.18, p = 0.02). Errors of omission were significantly higher (worse) in those with persistent anemia (β = 2.67, 95% CI 0.18, 5.17, p = 0.04). Very low Hgb levels were significantly associated with lower color-word inhibition/switching scores (β = - 1.33, 95% CI - 2.16, - 0.51; p = 0.002). Anemia and low GFR were associated with lower category fluency scores compared to non-anemic subjects with higher GFR (β = - 1.09, 95% CI - 2.09, - 0.10, p = 0.03). CONCLUSIONS The presence of anemia, in addition to its severity and duration in children with CKD, is associated with poorer scores on select measures of EF.

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
BACKGROUND The objectives of this study were to use electronic health record data from a US national multicenter pediatric network to identify a large cohort of children with CKD, evaluate CKD progression, and examine clinical risk factors for kidney function decline. METHODS This retrospective cohort study identified children seen between January 1, 2009, to February 28, 2022. Data were from six pediatric health systems in PEDSnet. We identified children aged 18 months to 18 years who met criteria for CKD: two eGFR values <90 and ≥15 ml/min per 1.73 m2 separated by ≥90 days without an intervening value ≥90. CKD progression was defined as a composite outcome: eGFR <15 ml/min per 1.73 m2, ≥50% eGFR decline, long-term dialysis, or kidney transplant. Subcohorts were defined based on CKD etiology: glomerular, nonglomerular, or malignancy. We assessed the association of hypertension (≥2 visits with hypertension diagnosis code) and proteinuria (≥1 urinalysis with ≥1+ protein) within 2 years of cohort entrance on the composite outcome. RESULTS Among 7,148,875 children, we identified 11,240 (15.7 per 10,000) with CKD (median age 11 years, 50% female). The median follow-up was 5.1 (interquartile range 2.8-8.3) years, the median initial eGFR was 75.3 (interquartile range 61-83) ml/min per 1.73 m2, 37% had proteinuria, and 35% had hypertension. The following were associated with CKD progression: lower eGFR category (adjusted hazard ratio [aHR] 1.44 [95% confidence interval (95% CI), 1.23 to 1.69], aHR 2.38 [95% CI, 2.02 to 2.79], aHR 5.75 [95% CI, 5.05 to 6.55] for eGFR 45-59 ml/min per 1.73 m2, 30-44 ml/min per 1.73 m2, 15-29 ml/min per 1.73 m2 at cohort entrance, respectively, when compared with eGFR 60-89 ml/min per 1.73 m2), glomerular disease (aHR 2.01 [95% CI, 1.78 to 2.28]), malignancy (aHR 1.79 [95% CI, 1.52 to 2.11]), proteinuria (aHR 2.23 [95% CI, 1.89 to 2.62]), hypertension (aHR 1.49 [95% CI, 1.22 to 1.82]), proteinuria and hypertension together (aHR 3.98 [95% CI, 3.40 to 4.68]), count of complex chronic comorbidities (aHR 1.07 [95% CI, 1.05 to 1.10] per additional comorbid body system), male sex (aHR 1.16 [95% CI, 1.05 to 1.28]), and younger age at cohort entrance (aHR 0.95 [95% CI, 0.94 to 0.96] per year older). CONCLUSIONS In large-scale real-world data for children with CKD, disease etiology, albuminuria, hypertension, age, male sex, lower eGFR, and greater medical complexity at start of follow-up were associated with more rapid decline in kidney function.

Abstract
BACKGROUND The landscape of available psychosocial services within pediatric nephrology care is poorly characterized. However, the effects of kidney disease on emotional health and health-related quality of life are well documented, as is the impact of social determinants of health on kidney disease outcomes. The objectives of this study were to assess pediatric nephrologists' perceptions of available psychosocial services and to elucidate inequities in access to psychosocial care. METHODS A web-based survey was distributed to members of the Pediatric Nephrology Research Consortium (PNRC). Quantitative analyses were performed. RESULTS We received responses from 49 of the 90 PNRC centers. With regards to dedicated services, social work was most commonly available (45.5-100%), followed by pediatric psychology (0-57.1%) and neuropsychology (0-14.3%), with no centers having embedded psychiatry. Availability of psychosocial providers was positively associated with nephrology division size, such that as center size increased, access to various psychosocial providers increased. Notably, the majority of respondents indicated that perceived need for psychosocial support exceeds that which is currently available, even at centers with higher levels of current support. CONCLUSIONS Within the US, there is wide variability in the availability of psychosocial services within pediatric nephrology centers despite a well-documented necessity for the provision of holistic care. Much work remains to better understand the variation in funding for psychosocial services and in utilization of psychosocial professionals in the pediatric nephrology clinic, and to inform key best practices for addressing the psychosocial needs of patients with kidney disease.

Abstract
BACKGROUND The United States organ allocation policies prioritize kidney-pancreas and other multiorgan candidates above pediatric kidney-alone candidates, but the effects of these policies are unclear. METHODS We used OPTN data to describe trends in multiorgan and kidney-pancreas transplantation and identify 377 next-sequential pediatric kidney-alone candidates between 4/1/2015 and 10/31/2019 for individual-level analysis. RESULTS Eleven percent of all kidneys were allocated as part of a multiorgan or kidney-pancreas transplant and 6% of pediatric kidney candidates were impacted. Pediatric next-sequential candidates accrued a median of 118 days (IQR 97-135 days) of additional wait time, and this was significantly longer for children who were Hispanic (p = .02), blood type B or O (p = .01), or had a cPRA ≥20% (p < .01). Eight pediatric next-sequential candidates (2%) were removed from the waitlist due to death or "too sick to transplant." 63% were transplanted with a kidney with a higher KDPI than the original multiorgan match (p < .01). Donor service areas with higher volumes of kidney-pancreas transplants had significantly longer additional wait times for pediatric next-sequential candidates (p = .01). CONCLUSIONS Current allocation policy results in longer waiting times and higher KDPI kidneys for pediatric kidney candidates. As multiorgan transplant volume is increasing, further consideration of allocation policy is necessary to maximize equality and utility.

Abstract
Chronic kidney disease (CKD) in children occurs mostly due to congenital anomalies of kidney and urinary tract and hereditary diseases. For advanced cases, a multidisciplinary team is needed to manage nutritional requirements and complications such as hypertension, hyperphosphatemia, proteinuria, and anemia. Neurocognitive assessment and psychosocial support are essential. Maintenance dialysis in children with end-stage renal failure has become the standard of care in many parts of the world. Children younger than 12 years have 95% survival after 3 years of dialysis initiation, whereas the survival rate for children aged 4 years or younger is about 82% at one year."

Abstract
BACKGROUND Children with chronic kidney disease (CKD) are at risk for neurocognitive deficits while simultaneously being at risk for chronic school absenteeism (≥ 18 school days per school year). Chronic school absenteeism compounds the negative impacts of CKD on academic achievement. In this study, we examined patient- and caregiver-reported factors associated with school absenteeism in children with non-dialysis- or transplant-dependent CKD in order to help identify which factors could be modifiable and ultimately improve school attendance. METHODS We utilized a combination of chart review and questionnaires distributed in person to patients and caregivers at a pediatric nephrology clinic between November 2018 and August 2019 to gather data. We used descriptive statistics to illustrate clinical characteristics of the children included in the study, caregiver characteristics, and examined reported reasons for missing school. RESULTS Twenty-one percent of participants (10/48) missed 18 full days of school or more, categorizing them as chronically absent. The top three reasons for missing school were doctor appointments, feeling sick, and being bullied. More specific sequelae of CKD were not highly reported as reasons for missing school. CONCLUSIONS Chronic absenteeism is a highly reported phenomenon among children with pediatric CKD. Given that missing school for doctor appointments was a top reason for absenteeism, this data suggests alternative appointment hours and virtual appointments may reduce chronic school absenteeism in children, and by extension improve their health, behavioral, and academic outcomes.

Abstract
Objective To compare specific attention functions for school-age children with chronic kidney disease (CKD) to those of a typically developing control group. Methods A cross-sectional study examined attention dimensions for children and adolescents with CKD (n = 30) in comparison to a typically developing control group (n = 41). The CKD group consisted of those receiving maintenance dialysis (n = 15) and those with mild/moderate CKD treated conservatively (n = 15). Measures aligning with Mirsky’s conceptual multidimensional model of attention were selected to compare groups across five dimensions of attention: Focus/Execute, Sustain, Stability, Shift, and Encode. Results Significant group differences were revealed, with the CKD group performing worse than controls on the Focus/Execute, Sustain, and Encode dimensions. The CKD group also had a larger proportion of children with scores one standard deviation or more below the mean on the Shift and Encode domains, suggesting an at-risk level of functioning in these dimensions. Secondary analyses showed disease severity to be correlated with worse attention functions for children with CKD. Conclusion Children with CKD may be vulnerable to subtle, specific deficits in numerous attention dimensions relative to their typically developing peers, particularly for those with more severe disease.

Associations between neurofilament light-chain protein, brain structure, and chronic kidney disease. Pediatr Res 2022; 91:1735-1740. [PMID: 34274959 PMCID: PMC8761779 DOI: 10.1038/s41390-021-01649-6] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/20/2021] [Revised: 06/24/2021] [Accepted: 06/30/2021] [Indexed: 12/12/2022]
Abstract
BACKGROUND Neurofilament light-chain (NfL) protein is a blood-based marker of neuroaxonal injury. We sought to (1) compare plasma NfL levels in children with chronic kidney disease (CKD) and healthy peers, (2) characterize the relationship between NfL level and kidney function, and (3) evaluate NfL as a predictor of abnormal brain structure in CKD. METHODS Sixteen children with CKD due to congenital kidney anomalies and 23 typically developing peers were included. Plasma NfL was quantified using single-molecule array immunoassay. Participants underwent structural magnetic resonance imaging. Multiple linear regression models were used to evaluate the association between plasma NfL levels, kidney function, and brain structure. RESULTS An age × group interaction was identified whereby NfL levels increased with age in the CKD group only (estimate = 0.65; confidence interval (CI) = 0.08-1.22; p = 0.026). Decreased kidney function was associated with higher NfL levels (estimate = -0.10; CI = -0.16 to -0.04; p = 0.003). Lower cerebellar gray matter volume predicted increased plasma NfL levels (estimate = -0.00024; CI = -0.00039 to 0.00009; p = 0.004) within the CKD group. CONCLUSIONS Children with CKD show accelerated age-related increases in NfL levels. NfL level is associated with lower kidney function and abnormal brain structure in CKD. IMPACT NfL is a component of the neuronal cytoskeleton providing structural axonal support. Elevated NfL has been described in relation to gray and white matter brain volume loss. We have previously described the abnormal cerebellar gray matter in CKD. We explored the relationship between NfL, CKD, and brain volume. There is an accelerated, age-related increase in NfL level in CKD. Within the CKD sample, NfL level is associated with abnormal kidney function and brain structure. Decreased kidney function may be linked to abnormal neuronal integrity in pediatric CKD.

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
Health care transition (HCT) from pediatric to adult-focused services is a longitudinal process driven by the collaboration and interactions of adolescent/young adult patients, their families, providers, health care agencies, and environment. Health care providers in both pediatric and adult-focused settings must collaborate, as patients' health self-management skills are acquired in the mid-20s, after they have transferred to adult-focused care. Our manuscript discusses the individual and family support systems as they relate to adolescents and young adults with chronic or end-stage kidney disease. In the individual domain, we discuss demographic/socioeconomic characteristics, disease complexity/course, cognitive capabilities, and self-management/self-advocacy. In the family domain, we discuss family composition/culture factors, family function, parenting style, and family unit factors. We provide a section dedicated to patients with cognitive and developmental disability. Furthermore, we discuss barriers for HCT preparation and offer solutions as well as activities for HCT preparation.

The association of neurodevelopmental abnormalities, congenital heart and renal defects in a tuberous sclerosis complex patient cohort. BMC Med 2022; 20:123.

Abstract
BACKGROUND Tuberous sclerosis complex (TSC) is a rare multi-system genetic disorder characterised by the presence of benign tumours throughout multiple organs including the brain, kidneys, heart, liver, eyes, lungs and skin, in addition to neurological and neuropsychiatric complications. Intracardiac tumour (rhabdomyoma), neurodevelopmental disorders (NDDs) and kidney disorders (KD) are common manifestations of TSC and have been linked with TSC1 and TSC2 loss-of-function mutations independently, but the dynamic relationship between these organ manifestations remains unexplored. Therefore, this study aims to characterise the nature of the relationship specifically between these three organs' manifestations in TSC1 and TSC2 mutation patients. METHODS Clinical data gathered from TSC patients across South Wales registered with Cardiff and Vale University Health Board (CAV UHB) between 1990 and 2020 were analysed retrospectively to evaluate abnormalities in the heart, brain and kidney development. TSC-related abnormalities such as tumour prevalence, location and size were analysed for each organ in addition to neuropsychiatric involvement and were compared between TSC1 and TSC2 mutant genotypes. Lastly, statistical co-occurrence between organ manifestations co-morbidity was quantified, and trajectories of disease progression throughout organs were modelled. RESULTS This study found a significantly greater mutational frequency at the TSC2 locus in the cohort in comparison to TSC1. An equal proportion of male and female patients were observed in this group and by meta-analysis of previous studies. No significant difference in characterisation of heart involvement was observed between TSC1 and TSC2 patients. Brain involvement was seen with increased severity in TSC2 patients, characterised by a greater prevalence of cortical tubers and communication disorders. Renal pathology was further enhanced in TSC2 patients, marked by increased bilateral angiomyolipoma prevalence. Furthermore, co-occurrence of NDDs and KDs was the most positively correlated out of investigated manifestations, regardless of genotype. Analysis of disease trajectories revealed a more diverse clinical outcome for TSC2 patients: however, a chronological association of rhabdomyoma, NDD and KD was most frequently observed for TSC1 patients. CONCLUSIONS This study marks the first empirical investigation of the co-morbidity between congenital heart defects (CHD), NDDs, and KDs in TSC1 and TSC2 patients. This remains a unique first step towards the characterisation of the dynamic role between genetics, heart function, brain function and kidney function during the early development in the context of TSC.

Abstract
This study aimed to explore the mechanism of fucoidan in chronic kidney disease (CKD)-triggered cognitive dysfunction. The adenine-induced ICR strain CKD mice model was applied, and RNA-Seq was performed for differential gene analysis between aged-CKD and normal mice. As a result, fucoidan (100 and 200 mg kg-1) significantly reversed adenine-induced high expression of urea, uric acid in urine, and creatinine in serum, as well as the novel object recognition memory and spatial memory deficits. RNA sequencing analysis indicated that oxidative and inflammatory signaling were involved in adenine-induced kidney injury and cognitive dysfunction; furthermore, fucoidan inhibited oxidative stress via GSK3β-Nrf2-HO-1 signaling and ameliorated inflammatory response through regulation of microglia/macrophage polarization in the kidney and hippocampus of CKD mice. Additionally, we clarified six hallmarks in the hippocampus and four in the kidney, which were correlated with CKD-triggered cognitive dysfunction. This study provides a theoretical basis for the application of fucoidan in the treatment of CKD-triggered memory deficits.

Abstract
The Chronic Kidney Disease in Children (CKiD) prospective cohort study was designed to address the neurocognitive, growth, cardiovascular, and disease progression of children and adolescents with mild to moderate CKD. The study has had continuous funding from NIDDK for 17 years and has contributed significant advances in pediatric CKD. The goals of this educational review are threefold: (1) to provide an overview of the neurocognitive and psychosocial studies from CKiD to date; (2) to provide best practice recommendations for those working with the neurocognitive and psychosocial aspects of pediatric CKD based on CKiD findings; and (3) to help chart future goals and directives for both research and clinical practice. This collection of 22 empirical studies has produced a number of key findings for children and adolescents with mild to moderate CKD. While various studies suggest a relatively positive presentation for this population as a whole, without evidence of significant impairment or deterioration, findings do indicate the presence of neurocognitive dysfunction, emotional-behavioral difficulties, and lower quality of life for many children with CKD. These findings support the promotion of best practices that are accompanied by additional future clinical and research initiatives with this patient population.

Abstract
Rationale & Objective Children with chronic kidney disease (CKD) are subject to physical and psychosocial challenges, which may confer greater risk of developing psychiatric disorders. We sought to examine key psychiatric diagnoses in children with CKD compared with those in the general pediatric population and assess the correlation between parent-reported diagnosis and self-reported symptoms of depression. Study Design Cross-sectional. Setting & Participants Children ages 2-17 years receiving current medical care who participated in the Chronic Kidney Disease in Children Study (CKiD) or the National Survey of Children’s Health. Exposure CKD. Outcomes Parent-reported diagnoses of depression, anxiety, or attention-deficit and hyperactivity disorder (ADHD). Analytical Approach Using Poisson regression, we determined the age, sex, and race-adjusted prevalence ratio comparing diagnoses between children with CKD and those in the general population overall and within subgroups of sex, race, maternal education status, and CKD stage. Secondarily, we examined the correlation between depression status using standardized self-reported screening instrument scores and parent-reported diagnosis. Results Eight hundred seventy-five children with CKD and 72,699 children in the general population were included. Those with CKD had an adjusted prevalence ratio of 1.32 (95% CI, 1.01-1.73) for depression, 0.72 (95% CI, 0.52-0.99) for anxiety, and 1.03 (95% CI, 0.86-1.25) for ADHD. The results were similar across subgroups of CKD stage, sex, race, or maternal education. The correlation between parent-reported diagnosis and instrument-detected depression was weak, r = 0.13 (95% CI, 0.03-0.23). Limitations Retrospective parent- or self-reported data were used. Conclusions Children with CKD had a higher prevalence of parent-reported depression, equivalent prevalence of attention-deficit and hyperactivity disorder, and lower prevalence of anxiety diagnoses compared to other children. These findings are inconsistent with results of prior studies and suggest that baseline assessments used in CKiD may have limited utility in describing psychiatric disorders among children with CKD. Improved mental health assessment approaches in pediatric nephrology are needed.

Abstract
OBJECTIVE To investigate the associations between neurocognition and white matter integrity in children with chronic kidney disease (CKD). STUDY DESIGN This cross-sectional study included 17 boys (age 6-16 years) with a diagnosis of mild to moderate (stages 1-3, nondialysis/nontransplant) CKD because of congenital anomalies of the kidney and urinary tract and 20 typically developing community controls. Participants underwent 3T neuroimaging and diffusion-weighted magnetic resonance imaging to assess white matter fractional anisotropy. Multivariable linear regression models were used to evaluate the impact of each group (controls vs CKD) on white matter fractional anisotropy, adjusting for age. Associations between white matter fractional anisotropy and neurocognitive abilities within the CKD group were also evaluated using regression models that were adjusted for age. The false discovery rate was used to account for multiple comparisons; wherein false discovery values <0.10 were considered significant. RESULTS Global white matter fractional anisotropy was reduced in patients with CKD relative to controls (standardized estimate = -0.38, 95% CI -0.69:-0.07), driven by reductions within the body of the corpus callosum (standardized estimate = -0.44, 95% CI -0.75:-0.13), cerebral peduncle (SE = -0.37, 95% CI -0.67:-0.07), cingulum (hippocampus) (standardized estimate = -0.45, 95% CI -0.75:-0.14), and posterior limb of the internal capsule (standardized estimate = -0.46, 95% CI -0.76:-0.15). Medical variables and neurocognitive abilities were not significantly associated with white matter fractional anisotropy. CONCLUSIONS White matter development is vulnerable in children with CKD because of congenital causes, even prior to the need for dialysis or transplantation.

Abstract
Chronic kidney disease (CKD) affects more than 37 million American adults. Adult-onset CKD is typically attributed to acquired comorbidities such as aging, type II diabetes, and cardiovascular disease. Conversely, congenital abnormalities of the kidney and urinary tract are the most common cause of CKD in children. Both adult and pediatric patients with CKD are at risk for neurocognitive dysfunction, particularly in the domain of executive function. The exact mechanism for neurocognitive dysfunction in CKD is not known; however, it is conceivable that the multisystemic effects of CKD—including hypertension, acidosis, anemia, proteinuria, and uremic milieu—exert a detrimental effect on the brain. Quantitative neuroimaging modalities, such as magnetic resonance imaging (MRI), provide a non-invasive way to understand the neurobiological underpinnings of cognitive dysfunction in CKD. Adult patients with CKD show differences in brain structure; however, much less is known about the impact of CKD on neurodevelopment in pediatric patients. Herein, this review will summarize current evidence of the impact of CKD on brain structure and function and will identify the critical areas for future research that are needed to better understand the modifiable risk factors for abnormal brain structure and function across both pediatric and adult CKD populations.

Abstract
Pediatric kidney transplant recipients are distinguished from adult recipients by the need for many decades of graft function, the potential effect of CKD on neurodevelopment, and the changing immune environment of a developing human. The entire life of an individual who receives a transplant as a child is colored by their status as a transplant recipient. Not only must these young recipients negotiate all of the usual challenges of emerging adulthood (transition from school to work, romantic relationships, achieving independence from parents), but they must learn to manage a life-threatening medical condition independently. Regardless of the age at transplantation, graft failure rates are higher during adolescence and young adulthood than at any other age. All pediatric transplant recipients must pass through this high-risk period. Factors contributing to the high graft failure rates in this period include poor adherence to treatment, potentially exacerbated by the transfer of care from pediatric- to adult-oriented care providers, and perhaps an increased potency of the immune response. We describe the characteristics of pediatric kidney transplant recipients, particularly those factors that may influence their care throughout their lives. We also discuss the risks associated with the transition from pediatric- to adult-oriented care and provide some suggestions to optimize the transition to adult-oriented transplant care and long-term outcomes.

Abstract
Pediatric chronic kidney disease (CKD) appears to be a heterogeneous group of conditions, but this heterogeneity has not been explored with respect to its impact on neurocognitive functioning. This study investigated the neurocognitive functioning of those with glomerular (G) vs. non-glomerular (NG) diagnoses. Data from the North American CKiD Study were employed and the current study included 1,003 children and adolescents with mild to moderate CKD. The G Group included 260 participants (median age = 14.7 years) and the NG Group included 743 individuals (median age = 9.0 years). Neurocognitive measures assessed IQ, inhibitory control, attention regulation, problem solving, working memory, and overall executive functioning. Data from all visits were included in the linear mixed model analyses. After adjusting for sociodemographic and CKD-related covariates, results indicated no differences between the diagnostic groups on measures of IQ, problem solving, working memory, and attention regulation. There was a trend for the G group to receive better parent ratings on their overall executive functions (p < 0.07), with a small effect size being present. Additionally, there was a significant G group X hypertension interaction (p < 0.003) for inhibitory control, indicating that those with both a G diagnosis and hypertension performed more poorly than the NG group with hypertension. These findings suggest that the separation of G vs. NG CKD produced minimal, but specific group differences were observed. Ongoing examination of the heterogeneity of pediatric CKD on neurocognition, perhaps at a different time point in disease progression or using a different model, appears warranted.

Abstract
BACKGROUND Chronic kidney disease (CKD) is associated with cognitive dysfunction. Cognitive function in children with CKD residing in developing countries has not been previously reported. METHODS This cross-sectional study included children aged 6-18 years with CKD stages 2-5D and kidney transplant. Cognitive function was assessed by WISC-V for children from 6-16 years of age. In adolescents 17-18 years of age, WAIS-III was used. Factors associated with cognitive dysfunction were identified using multivariable regression analysis. RESULTS Thirty-seven children with median age 13.9 (11.3-15.7) years were recruited. The median full-scale intelligence quotient (FSIQ) was 83.0 (71.0-95.0). Below-average cognitive function (FSIQ <90) was identified in 24 children (64.8%), 24.3% of whom had cognitive impairment (FSIQ <70). Most children (94.6%) scored lower than average on at least 1 cognitive domain. Kidney replacement therapy (p = 0.03) and low family income (p = 0.02) were associated with below-average cognitive function in multivariable logistic regression analysis. Children who left school and low family income were significantly associated with cognitive function. The FSIQ of children who had left school was 12.94 points lower than the educated group (p = 0.046). In addition, every 10,000 Thai Baht (approximately 330 United States dollars) increase in family income correlated with 1.58 increase in FSIQ (p = 0.047). CONCLUSION Cognitive dysfunction was commonly found in children with CKD. Socioeconomic factors, particularly school attendance and family income, were associated with cognitive dysfunction. Cognitive evaluation is suggested for children with CKD who have socioeconomic risk factors. "A higher resolution version of the Graphical abstract is available as Supplementary information."

Abstract
BACKGROUND Few data exist on the cognitive and academic functioning of children with chronic kidney disease (CKD) over the trajectory of their illness. We aimed to determine the association between CKD stages and cognitive and academic performance in children over time. METHODS We included 53 participants (aged 6-18 years) with CKD stages 1-5 (n = 37), on dialysis (n = 3), or with functioning kidney transplant (n = 22) from three units in Australia from 2015 to 2019. Participants undertook a series of psychometric tests and were invited for repeated assessments annually. We used linear regression and linear mixed models to investigate the effect of CKD stage, adjusted for socioeconomic status. RESULTS At baseline, full-scale intelligence quotient (FSIQ) (95%CI) of children on kidney replacement therapy (KRT) was in the low average range (87: 78, 96) and average (101: 95, 108) for children with CKD 1-5. Mean (95%CI) FSIQ, word reading, numerical operations, and spelling scores for children on KRT were 14.3 (- 25.3, - 3.3), 11 (- 18.5, - 3.6), 8.5 (- 17.6, 0.76), and 10 (- 18.6, - 1.3) points lower than children with CKD Stages 1-5. Spelling and numerical operations scores declined by 0.7 (- 1.4, - 0.1) and 1.0 (- 2.0, 0.2) units per year increase in age, regardless of CKD stage. CONCLUSIONS Children treated with KRT have low average cognitive abilities and lower academic performance for numeracy and literacy compared to both children with CKD 1-5 and to the general population. However, the rate of decline in academic performance over time is similar for children across the full spectrum of CKD.

Abstract
Inequity, racism, and health care disparities negatively impact the well-being of children with kidney disease. This review defines social determinants of health and describes how they impact pediatric nephrology care; outlines the specific impact of systemic biases and racism on chronic kidney disease care and transplant outcomes; characterizes and critiques the diversity of the current pediatric nephrology workforce; and aims to provide strategies to acknowledge and dismantle bias, address barriers to care, improve diversity in recruitment, and strengthen the pediatric nephrology community. By recognizing historical and current realities and limitations, we can move forward with strategies to address racism and bias in our field and clinical practices, thereby cultivating inclusive training and practice environments.

Abstract
We investigated the effects of high- vs. standard-dose vitamin D supplementation on kidney function and bone metabolism in children with chronic kidney disease (CKD). Children were randomized to receive one of two formulations: 75 participants received 2,000 IU/D of oral supplementation of vitamin D, while 75 participants received 400 IU/d for a minimum of 4 months. We investigated the effects of vitamin D supplementation on kidney-related indicators and bone metabolism-related indicators at different doses. A total of 158 participants were screened, among whom 150 met the inclusion criteria. The indicators of chronic kidney disease such as eGFR and serum uric acid were negatively correlated with the 25(OH)D level and BMD. Serum 25(OH)D and osteocalcin levels were positively correlated with spine BMD. The standard dose of vitamin D can improve the serum uric acid level, but high doses of vitamin D supplementation had no significant effect on the serum uric acid level. High doses of vitamin D supplementation can also improve the alkaline phosphatase level. When comparing the results of different doses of vitamin D supplementation, it was found that high-dose vitamin D supplementation did not improve bone density in the spine and femur neck relative to the standard dose of vitamin D but improved hypocalcemia and N-terminal propeptide of the human procollagen type I (PINP) level. Among the children with clinical kidney disease, high-dose vitamin D treatment for 4 months resulted in statistically significant improvement in kidney function but no significant difference in bone metabolism compared with the standard-dose vitamin D treatment.

Abstract
This cross-sectional study provides preliminary findings from one of the first functional brain imaging studies in children with chronic kidney disease (CKD). The sample included 21 children with CKD (ages, 14.4 ± 3.0 y) and 11 healthy controls (ages, 14.5 ± 3.4 y). Using functional magnetic resonance imaging during a visual-spatial working memory task, findings showed that the CKD group and healthy controls invoked similar brain regions for encoding and retrieval phases of the task, but significant group differences were noted in the activation patterns for both components of the task. For the encoding phase, the CKD group showed lower activation in the posterior cingulate, anterior cingulate, precuneus, and middle occipital gyrus than the control group, but more activation in the superior temporal gyrus, middle frontal gyrus, middle temporal gyrus, and the insula. For the retrieval phase, the CKD group showed underactivation for brain systems involving the posterior cingulate, medial frontal gyrus, occipital lobe, and middle temporal gyrus, and greater activation than the healthy controls in the postcentral gyrus. Few group differences were noted with respect to disease severity. These preliminary findings support evidence showing a neurologic basis to the cognitive difficulties evident in pediatric CKD, and lay the foundation for future studies to explore the neural underpinnings for neurocognitive (dys)function in this population.

Abstract
An increasing amount of literature has indicated that chronic kidney disease (CKD) is associated with cognitive deficits that increase with worsening disease severity. Although abnormalities in brain structure have been widely documented, few studies to date have examined the functioning of brain areas associated with the specific cognitive domains affected by CKD (namely, attention and executive functions). Furthermore, few studies have examined functional connectivity among CKD youth who are relatively early in the course of the disease. The present study used functional magnetic resonance imaging to examine the resting state connectivity in 67 youth with CKD (mean age, 17 y) and 58 age-matched healthy controls. Using seed-based multiple regression, decreased connectivity was observed within the anterior cingulate portion of the default mode network. In addition, decreased connectivity within the dorsolateral prefrontal cortex, paracingulate gyrus, and frontal pole were correlated significantly with disease severity. These data indicate that connectivity deficits in circuits implementing attentional processes may represent an early marker for cognitive decline in CKD.

Abstract
Pediatric chronic kidney disease (CKD) is associated with deficits in neurocognitive functioning, ranging from mild to severe, and correlated with the severity of kidney disease. Clinical variables that are associated with neurocognitive deficits include lower kidney function, hypertension, proteinuria, and metabolic acidosis. Commonly reported neurocognitive difficulties include academic underachievement and deficits in attention regulation and executive function as well as somewhat lower intellectual abilities compared with peer and normative data. Although often mild, these neurocognitive deficits may have broad implications for quality of life and likely contribute to both poorer high school graduation rates and long-term underemployment in the adult CKD population. The presence of neurocognitive deficits in predialytic CKD has been well characterized, but further longitudinal research is warranted to describe cognitive changes as children progress from early stage CKD to kidney replacement therapy. Such studies should include both cognitive and neuroimaging evaluations to better inform the impact of CKD progression on neurocognitive outcomes.

Abstract
BACKGROUND Chronic kidney disease (CKD) has a negative impact on growth and development in children and is a risk factor for neurocognitive impairment; however, there is limited research on the cognitive function of children and adolescents with CKD. This study therefore aimed to investigate the mean intelligence and risk factors for low intelligence in children and adolescents with CKD. METHODS Eighty-one patients with CKD under 18 years old were included in the KoreaN cohort study for Outcomes in patients With Pediatric Chronic Kidney Disease (KNOW-Ped CKD). Participants completed either the Wechsler Intelligence Scale for Children (6-16 years), or Wechsler Adult Intelligence Scale (> 16 years). RESULTS The mean full-scale intelligence quotient (IQ) was 91 ± 19; 24.7% of participants scored a full-scale IQ below 80. Participants with a short stature (height Z scores < -1.88), failure to thrive (weight Z scores < -1.65), more severe CKD stage (≥ IIIb), longer duration of CKD (≥ 5 years), and those who were Medicare or Medicaid beneficiaries, had significantly lower mean full-scale IQs. CONCLUSION On linear regression analysis, the association between the full-scale IQ, and longer duration of CKD and growth failure, remained significant after controlling for demographic and clinical variables. It is therefore necessary to investigate cognitive impairment in pediatric patients with CKD who exhibit growth failure or for a longer postmorbid period. It is believed that early interventions, such as kidney transplantation, will have a positive effect on IQ in children with CKD, as the disease negatively affects IQ due to poor glomerular filtration rate over time.

Abstract
Children suffering from chronic kidney disease (CKD) have the apparent highest risk for the development of cardiovascular disease (CVD) at a young age. While symptoms of CVD are characteristically absent in childhood and adolescence, remodelling of the myocardium, medium and large-sized arteries and of the microcirculation is clinically significant and can be assessed with non-invasive technology. Kidney disease and its progression are the driver of CVD, mediated by an unparalleled accumulation of risk factors converging on several comorbid conditions including hypertension, anaemia, dyslipidaemia, disturbed mineral metabolism and chronic persistent inflammation. Large prospective paediatric cohorts studies have provided valuable insights into the pathogenesis and the progression of CKD-induced cardiovascular comorbidity and have characterised the cardiovascular phenotype in young patients. They have also provided the rationale for close monitoring of risk factors and have defined therapeutic targets. Recently discovered new biomarkers could help identify the individual risk for CVD. Prevention of CVD by aggressive therapy of modifiable risk factors is essential to enable long-term survival of young patients with CKD.

Kidney Outcomes and Hypertension in Survivors of Wilms Tumor: A Prospective Cohort Study. J Pediatr 2021; 230:215-220.e1. [PMID: 33290810 PMCID: PMC7914174 DOI: 10.1016/j.jpeds.2020.12.005] [Citation(s) in RCA: 10] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/24/2020] [Revised: 11/23/2020] [Accepted: 12/02/2020] [Indexed: 10/22/2022]
Abstract
OBJECTIVE To assess the prevalence of therapy-related kidney outcomes in survivors of Wilms tumor (WT). STUDY DESIGN This prospective cohort study included survivors of WT who were ≥5 years old and ≥1 year from completing therapy, excluding those with preexisting hypertension, prior dialysis, or kidney transplant. Participants completed 24-hour ambulatory blood pressure monitoring (ABPM). Abnormal blood pressure (BP) was defined as ≥90th percentile. Masked hypertension was defined as having normal office BP and abnormal ABPM findings. Urine was analyzed for kidney injury molecule-1, interleukin-18, epidermal growth factor, albumin, and creatinine. The estimated glomerular filtration rate (eGFR) was calculated using the bedside chronic kidney disease in children equation. Recent kidney ultrasound examinations and echocardiograms were reviewed for contralateral kidney size and left ventricular hypertrophy, respectively. Clinical follow-up data were collected for approximately 2 years after study enrollment. RESULTS Thirty-two participants (median age, 13.6 years [IQR, 10.5-16.3 years]; 75% stage 3 or higher WT) were evaluated at a median of 8.7 years (IQR, 6.5-10.8 years) after therapy; 29 participants underwent unilateral radical nephrectomy, 2 bilateral partial nephrectomy, and 1 radical and contralateral partial nephrectomy. In this cohort, 72% received kidney radiotherapy and 75% received doxorubicin. Recent median eGFR was 95.6 mL/min/1.73 m2 (IQR, 84.6-114.0; 11 [34%] had an eGFR of <90 mL/min/1.73 m2). Abnormal ABPM results were found in 22 of 29 participants (76%), masked hypertension in 10 of 29 (34%), and microalbuminuria in 2 of 32 (6%). Of the 32 participants, 22 (69%) had abnormal epidermal growth factor; few had abnormal kidney injury molecule-1 or interleukin-18. Seven participants with previous unilateral nephrectomy lacked compensatory contralateral kidney hypertrophy. None had left ventricular hypertrophy. CONCLUSIONS In survivors of WT, adverse kidney outcomes were common and should be closely monitored.

Early pediatric chronic kidney disease is associated with brain volumetric gray matter abnormalities. Pediatr Res 2021; 89:526-532. [PMID: 33069166 PMCID: PMC7981243 DOI: 10.1038/s41390-020-01203-w] [Citation(s) in RCA: 10] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/27/2020] [Revised: 09/03/2020] [Accepted: 09/10/2020] [Indexed: 11/09/2022]
Abstract
BACKGROUND The impact of pediatric chronic kidney disease (pCKD) on the brain remains poorly defined. The objective of this study was to compare brain morphometry between children with early-stage pCKD and typically developing peers using structural magnetic resonance imaging (MRI). METHODS The sample age range was 6-16 years. A total of 18 children with a diagnosis of pCKD (CKD stages 1-3) due to congenital anomalies of the kidney and urinary tract and 24 typically developing peers were included. Volumetric data from MRI and neurocognitive testing were compared using linear models including pCKD status, age, maternal education level, and socioeconomic status. RESULTS Cerebellar gray matter volume was significantly smaller in pCKD, t(38) = -2.71, p = 0.01. In contrast, cerebral gray matter volume was increased in pCKD, t(38) = 2.08, p = 0.04. Reduced cerebellum gray matter volume was associated with disease severity, operationalized as estimated glomerular filtration rate (eGFR), t(14) = 2.21, p = 0.04 and predicted lower verbal fluency scores in the pCKD sample. Enlarged cerebral gray matter in the pCKD sample predicted lower scores on mathematics assessment. CONCLUSIONS This study provides preliminary evidence for a morphometric underpinning to the cognitive deficits observed in pCKD. IMPACT The impact of pediatric chronic kidney disease (CKD) on the brain remains poorly defined, with no data linking brain morphometry and observed cognitive deficits noted in this population. We explored the relationship between brain morphometry (using structural magnetic resonance imaging), cognition, and markers of CKD. Cerebellar and cerebral gray matter volumes are different in early CKD. Volumetric decreases in cerebellar gray matter are predicted by lower eGFR, suggesting a link between disease and brain morphometry. Reduced cerebellar gray matter predicted lower verbal fluency for those with pCKD. Enlarged cerebral gray matter in the pCKD sample predicted lower mathematics performance.

Chronic kidney disease impacts health-related quality of life of children in Uganda, East Africa. Pediatr Nephrol 2021; 36:323-331.

Abstract
BACKGROUND Limited data exist about causes of chronic kidney disease (CKD) and impact on health-related quality of life (HRQoL) in African children. We evaluated types of kidney disease in Ugandan children 0-18 years and compared HRQoL in children with CKD or with benign or resolving kidney disease (non-CKD) to assess predictors of HRQoL. METHODS Demographic, socioeconomic, and clinical data were obtained for this cross-sectional study. Pediatric Quality of Life Core Scale™ (PedsQL) was used to survey 4 domains and overall HRQoL. CKD and non-CKD scores were compared using unpaired t test. HRQoL predictors were evaluated using linear and logistic regression analyses. RESULTS One hundred forty-nine children (71 CKD, 78 non-CKD; median age 9 years; male 63%) had the following primary diseases: nephrotic syndrome (56%), congenital anomalies of the urinary tract (CAKUT) (19%), glomerulonephritis (17%), and other (8%). CAKUT was the predominant etiology (39%) for CKD; 63% had advanced stages 3b-5. Overall HRQoL scores were significantly lower for CKD (57 vs. 86 by child report, p < 0.001; 63 vs. 86 by parent proxy report, p < 0.001). Predictors of lower HRQoL were advanced CKD stages 3b-5, primary caregiver non-parent, vitamin D deficiency, and anemia. CONCLUSION Like other parts of the world, CAKUT was the main cause of CKD. Most CKD children presented at late CKD stages 3b-5. Compared with non-CKD, HRQoL in CKD was much lower; only two-thirds attended school. Vitamin D deficiency and anemia were potentially modifiable predictors of low HRQoL. Interventions with vitamin D, iron, and erythropoietin-stimulating agents might lead to improved HRQoL.

Abstract
Neurodevelopmental impairments have been recognised as a major association of paediatric kidney disease and bladder dysfunction, presenting challenges to clinicians and families to provide reasonable adjustments in order to allow access to investigations and treatments. Autism spectrum disorder (ASD) is a common neurodevelopmental disorder characterised by impairments in social interaction/communication and repetitive sensory-motor behaviours. Mental health, learning and physical co-morbidities are common. There is emerging evidence that ASD and kidney disease have some overlaps with genetic copy number variants and environmental factors contributing to shared pathogenesis. Prevalence rates of ASD in kidney disease are currently not known. A high index of suspicion of underlying ASD is required when a young person presents with communication difficulties, anxiety or behaviour that challenges, which should then trigger referral for a neurodevelopmental and behavioural assessment. We discuss practical approaches for providing care, which include understanding methods of communication and sensory, behavioural and environmental adaptations.

Abstract
BACKGROUND Primary nephrogenic diabetes insipidus (NDI) is a rare disorder and little is known about treatment practices and long-term outcome. METHODS Paediatric and adult nephrologists contacted through European professional organizations entered data in an online form. RESULTS Data were collected on 315 patients (22 countries, male 84%, adults 35%). Mutation testing had been performed in 270 (86%); pathogenic variants were identified in 258 (96%). The median (range) age at diagnosis was 0.6 (0.0-60) years and at last follow-up 14.0 (0.1-70) years. In adults, height was normal with a mean (standard deviation) score of -0.39 (±1.0), yet there was increased prevalence of obesity (body mass index >30 kg/m2; 41% versus 16% European average; P < 0.001). There was also increased prevalence of chronic kidney disease (CKD) Stage ≥2 in children (32%) and adults (48%). Evidence of flow uropathy was present in 38%. A higher proportion of children than adults (85% versus 54%; P < 0.001) received medications to reduce urine output. Patients ≥25 years were less likely to have a university degree than the European average (21% versus 35%; P = 0.003) but full-time employment was similar. Mental health problems, predominantly attention-deficit hyperactivity disorder (16%), were reported in 36% of patients. CONCLUSION This large NDI cohort shows an overall favourable outcome with normal adult height and only mild to moderate CKD in most. Yet, while full-time employment was similar to the European average, educational achievement was lower, and more than half had urological and/or mental health problems.

Abstract
Brain growth and development occur at peak rates in early childhood through adolescence, and for some children, this must happen in conjunction with chronic kidney disease (CKD), associated medical conditions, and their treatment(s). This review provides an overview of key findings to date on the topic of the brain in pediatric CKD. Here, we specifically address the topics of neuroimaging and cognition in pediatric CKD with consideration to biomarkers of disease progression that may impact cognition. Current cognitive data suggest that most children with mild to moderate CKD do not exhibit significant cognitive impairments, but, rather, the presence of somewhat lower intellectual abilities and subtle deficits in selected executive functions. Although promising, modern neuroimaging data remain inconclusive in linking cognitive findings to neuroimaging correlates in the pediatric CKD population. Certainly, it is important to note that even subtle cognitive concerns can present barriers to learning, social functioning, and overall quality of life if not appropriately recognized or addressed. Further longitudinal research utilizing concurrent and targeted cognitive and neuroimaging evaluations is warranted to better understand the impact of CKD progression on brain development and associated neurocognitive outcomes.

Abstract
PURPOSE To investigate cerebral amplitude of low-frequency fluctuations (ALFF) changes during a single hemodialysis (HD) in end-stage renal disease (ESRD) patients who need maintenance HD. MATERIALS AND METHODS A total of 24 patients and 27 healthy subjects were included. The patients underwent neuropsychological tests and took twice resting-state fMRI (rs-fMRI) (before and after HD). Healthy group had one rs-fMRI. The zALFF based on rs-fMRI was calculated. Paired t and independent t test was applied to compare zALFF among groups. The associations between zALFF and duration of HD, ultrafiltration volume, and neuropsychological tests was calculated by partial correlation. RESULTS Compared to healthy group, patients before HD showed significant worse performances on digit symbol test (DST) and serial dotting test (SDT). Patients after HD performed DST better than before HD. The patients after HD showed higher zALFF in left putamen than before HD. Multiple regions of both HD groups showed significant lower zALFF than healthy group. The zALFF of left putamen of patients after HD was significant negative correlated with the ultrafiltration volume (R = -0.679). The zALFF in patients before HD exhibited significantly positive or negative correlations with DST and SDT in multiple regions. The zALFF of patients after HD significantly negative correlated with DST in right temporal, positive and negative correlated with ultrafiltration volume in right frontal, left putamen respectively. CONCLUSION ESRD patients showed changed spontaneous brain activity and cognitive impairments. After a single HD session, patients performed better in neuropsychological test, and spontaneous brain activity changed in left putamen. Ultrafiltration volume might be associated with activity of left putamen.

Pediatr Nephrol 2020; 35:1315-1321. [PMID: 32095895 PMCID: PMC8979491 DOI: 10.1007/s00467-020-04503-9] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/04/2019] [Revised: 01/18/2020] [Accepted: 02/10/2020] [Indexed: 01/07/2023]
Abstract
BACKGROUND This study aimed to determine stroke incidence and assess the association between stroke and neurocognitive functioning in children with chronic kidney disease (CKD). METHODS Data was derived from the Chronic Kidney Disease in Children (CKiD) cohort study. Stroke incidence was calculated after confirming self-reports of stroke occurrence by chart review. Each participant with stroke was matched with three stroke-free participants and performance on selected neurocognitive measures was compared. Wilcoxon rank-sum tests were used to compare neurocognitive test scores. Effect size (ES) was estimated using a modified version of Cohen's U3 metric that measures the excess percentage of the stroke group worse than the median of the control group. RESULTS Of 891 subjects, five (0.56%) had a confirmed stroke prior to study entry. Median time at risk was 15.7 years [interquartile range, 12.5-18.4]. Estimated incidence rate of history of stroke was 36.8 per 100,000 children per year (95% confidence interval 15.3, 88.5). Controls and subjects with stroke were similar in age, CKD duration, race, and maternal education. ES for many of the neurocognitive comparisons was moderate to large. Subjects in the CKID cohort with a history of stroke had lower scores on spatial span reverse, spatial span forward, and design fluency, and worse parent ratings on BRIEF Metacognition Index compared to a matched sample of children with CKD without stroke. CONCLUSIONS Children with CKD have an increased incidence of prior ischemic stroke compared to the general pediatric population. A stroke history was associated with poorer performance on neurocognitive measures. Graphical abstract.
