Long-term quality of life and social outcome of childhood end-stage renal disease

Prevalence and associated factors of impaired kidney functions among children and adolescents in India: insights from the Comprehensive National Nutrition Survey (CNNS) 2016-18

BACKGROUND

Chronic kidney disease (CKD) is a significant public health problem. The burden of CKD in children and adolescents in India is not well described. We used data from the recent Comprehensive National Nutrition Survey (CNNS) to estimate the prevalence of impaired kidney function (IKF) and its determinants in children and adolescents between the ages of 5 and 19.

METHODS

CNNS 2016-18 adopted a multi-stage sampling design using probability proportional to size sampling procedure after geographical stratification of urban and rural areas. Serum creatinine was tested once in 24,690 children and adolescents aged 5-19 years. The estimated glomerular filtration rate (eGFR) was derived using the revised Schwartz equation. The eGFR value below 60 ml/min/1.73 m2 is defined as IKF. Bivariate analysis was done to depict the weighted prevalence, and multivariable logistic regression examined the predictors of IKF.

RESULTS

The mean eGFR in the study population was 113.3 + 41.4 mL/min/1.73 m2. The overall prevalence of IKF was 4.9%. The prevalence in the 5-9, 10-14, and 15-19 year age groups was 5.6%, 3.4% and 5.2%, respectively. Regression analysis showed age, rural residence, non-reserved social caste, less educated mothers, Islam religion, children with severe stunting or being overweight/obese, and residence in Southern India to be predictors of IKF.

CONCLUSIONS

The prevalence of IKF among children and adolescents in India is high compared to available global estimates. In the absence of repeated eGFR-based estimates, these nationally representative estimates are intriguing and call for further assessment of socio-demographic disparities, genetics, and risk behaviours to have better clinical insights and public health preparedness.

Life outcomes after paediatric kidney transplantation: a qualitative, biographical study in long-term survivors

OBJECTIVE

The objective of this study was to analyse the narrative life stories of children with end-stage kidney disease (ESKD) and their families to determine how health professionals can effectively support these children to achieve better life outcomes.

DESIGN

Qualitative narrative biographic study.

SETTING

We invited every long-term survivor of paediatric kidney transplants and their families at the Medical University of Vienna between 2008 and 2013 to participate in this study.

PARTICIPANTS

Nineteen patients (women: n=8, 42%) and 34 family members (women: n=22, 65%) were interviewed. The patients had a mean age of 7.6 (SD±5.6) years at the time of transplantation and 22.2 (SD±5.4) at the time of interview.

MAIN OUTCOMES MEASURES

A qualitative narrative biographical analysis was combined with computational structured topic models using the Latent Dirichlet Allocation.

RESULTS

The overarching finding was the desire for normality in daily life in long-term survivors and their families but with different perceptions of what normality looks like and predominance of this aspect evolving. Different strategies were used by patients (focused on their advancement) and caregivers (normality for all family members). Siblings played a major role in supporting survivors' social inclusion.

CONCLUSIONS

The strong desire for normality confirms recent findings of the Standardised Outcomes in Nephrology Group initiative, which proposes survival and life participation as core outcomes in children with chronic kidney disease. Our study should be a starting point for an international effort to identify typologies and stratified interventions for children with ESKD and their families, particularly siblings.

Cost-Effectiveness of School Urinary Screening for Early Detection of IgA Nephropathy in Japan

Importance

The evidence for and against screening for chronic kidney disease in youths who are asymptomatic is inconsistent worldwide. Japan has been conducting urinary screening in students for 50 years, allowing for a full economic evaluation that includes the clinical benefits of early detection and intervention for chronic kidney disease.

Objectives

To evaluate the clinical effectiveness and cost-effectiveness of school urinary screening in Japan, with a focus on the benefits of the early detection and intervention for IgA nephropathy, and to explore key points in the model that are associated with the cost-effectiveness of the school urinary screening program.

Design, Setting, and Participants

This economic evaluation with a cost-effectiveness analysis used a computer-simulated Markov model from the health care payer's perspective among a hypothetical cohort of 1 000 000 youths aged 6 years in first grade in Japanese elementary schools, followed up through junior and high school. The time horizon was lifetime. Costs and clinical outcomes were discounted at a rate of 2% per year. Costs were calculated in Japanese yen and 2020 US dollars (¥107 = US $1).

Interventions

School urinary screening for IgA nephropathy was compared with no screening.

Main Outcomes and Measures

Outcomes were costs and quality-adjusted life-years (QALYs). Cost-effectiveness was determined by evaluating whether the incremental cost-effectiveness ratio (ICER) per QALY gained remained less than ¥7 500 000 (US $70 093).

Results

In the base case analysis, the ICER was ¥4 186 642 (US $39 127)/QALY, which was less than the threshold. There were 60.3 patients/1 000 000 patients in the no-screening strategy and 31.7 patients/1 000 000 patients in the screening strategy with an end-stage kidney disease. Cost-effectiveness improved as the number of screenings decreased (screening frequency <3 times: incremental cost, -¥75 [US $0.7]; incremental QALY, 0.00025; ICER, dominant), but the number of patients with end-stage kidney disease due to IgA nephropathy increased (40.9 patients/1 000 000 patients). Assuming the disutility due to false positives had a significant impact on the analysis; assuming a disutility of 0.01 or more, the population with no IgA nephropathy had an ICER greater than the threshold (¥8 304 093 [US $77 608]/QALY).

Conclusions and Relevance

This study found that Japanese school urinary screening was cost-effective, suggesting that it may be worthy of resource allocation. Key factors associated with cost-effectiveness were screening cost, the probability of incident detection outside of screening, and IgA nephropathy incidence, which may provide clues to decision-makers in other countries when evaluating the program in their own context.

Longitudinal changes of health-related quality of life in childhood chronic kidney disease

BACKGROUND

Few longitudinal studies have evaluated the impact of chronic kidney disease (CKD) duration on health-related quality of life (HRQOL). The study's aim was to determine how HRQOL changes over time in childhood CKD.

METHODS

Study participants were children in the chronic kidney disease in children (CKiD) cohort who completed the pediatric quality of life inventory (PedsQL) on three or more occasions over the course of two or more years. Generalized gamma (GG) mixed-effects models were applied to assess the effect of CKD duration on HRQOL while controlling for selected covariates.

RESULTS

A total of 692 children (median age = 11.2) with a median of 8.3 years duration of CKD were evaluated. All subjects had a GFR greater than 15 ml/min/1.73 m2. GG models with child self-report PedsQL data indicated that longer CKD duration was associated with improved total HRQOL and the 4 domains of HRQOL. GG models with parent-proxy PedsQL data indicated that longer duration was associated with better emotional but worse school HRQOL. Increasing trajectories of child self-report HRQOL were observed in the majority of subjects, while parents less frequently reported increasing trajectories of HRQOL. There was no significant relationship between total HRQOL and time-varying GFR.

CONCLUSIONS

Longer duration of the disease is associated with improved HRQOL on child self-report scales; however, parent-proxy results were less likely to demonstrate any significant change over time. This divergence could be due to greater optimism and accommodation of CKD in children. Clinicians can use these data to better understand the needs of pediatric CKD patients.

Understanding the impact of pediatric kidney transplantation on cognition: A review of the literature

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.

Validity and reliability of the Korean caregiver contribution to self-care chronic illness inventory

The contribution of caregivers to self-care for chronically ill patients is important for improving patient outcomes. The Caregiver Contribution to Self-Care Chronic Illness Inventory (CC-SC-CII) has been used to assess caregivers' contributions to three distinct aspects of self-care (maintenance, monitoring, and management) globally. This study aimed to examine the psychometrics of the Korean version of the CC-SC-CII with 230 family caregivers (mean age = 49.8 years, 70% women) of patients with chronic illness. We demonstrated that the CC-SC-CII-Korean has good reliability with acceptable internal consistency and construct validity for all three factors using confirmatory factor analysis. The CC-SC-CII-Korean is a reliable and valid instrument to measure the contributions of Korean caregivers to the self-care of patients with chronic illnesses.

Risk factors for severe acute kidney injury after pediatric hematopoietic cell transplantation

BACKGROUND

Acute kidney injury (AKI) is common after hematopoietic cell transplantation (HCT) and is associated with poorer outcomes. Risk factors for AKI after pediatric HCT are not fully understood. The study objective was to assess unique risk factors for AKI in the HCT population and evaluate post-HCT AKI patterns.

METHODS

We conducted a retrospective cohort study of patients < 21 years of age who underwent HCT at Seattle Children's Hospital/Fred Hutchinson Cancer Center from September 2008 to July 2017 (n = 484). We defined AKI using KDIGO criteria. We collected demographics, baseline HCT characteristics, post-HCT complications, and mortality. Multinomial logistic regression was used to estimate association between AKI and potential risk factors. We used adjusted Cox proportional hazard ratios to evaluate differences in mortality.

RESULTS

One hundred and eighty-six patients (38%) developed AKI. Seventy-nine (42%) had severe AKI and 27 (15%) required kidney replacement therapy. Fluid overload was common in all groups and 67% of those with severe AKI had > 10% fluid overload. Nephrology was consulted in less than 50% of those with severe AKI. In multivariable analysis, risk of severe AKI was lower in those taking a calcineurin inhibitor (CNI). Risk of death was higher in severe AKI compared to no AKI (RR 4.6, 95% CI 2.6-8.1).

CONCLUSIONS

AKI and fluid overload are common in pediatric patients after HCT. Severe AKI occurred less often with CNI use and was associated with higher mortality. Future interventions to reduce AKI and its associated complications such as fluid overload are approaches to reducing morbidity and mortality after HCT. A higher resolution version of the Graphical abstract is available as Supplementary information.

Safeguarding children and young people requiring kidney replacement therapy: challenges and potential opportunities

Kidney replacement therapy (KRT) makes considerable physical and psychological demands on children, young people and their families. The impact can be wide-ranging, affecting education, employment, mental health, finances and relationships for both child and caregiver. It is vitally important for those working with these families to recognise the psychosocial challenges they face and to know the range of interventions available. This article explores the psychosocial impact of KRT, considering opportunities to minimise risk and optimise outcomes for children, young people and their families.

The Use of Patient-Reported Outcome Measures in Daily Clinical Practice of a Pediatric Nephrology Department

(1) Background: Health-related quality of life (HRQoL) is lower in patients with chronic kidney disease (CKD) compared to the general population. In 2011, the KLIK PROM portal was implemented in the Emma Children’s Hospital to monitor and discuss HRQoL in daily care. This study describes and assesses the implementation and use of the KLIK PROM portal in the pediatric nephrology department. (2) Methods: CKD patients (self-report, if 8–18 years of age) and their parents (proxy-report, if 1–8 years) were invited to complete HRQoL patient-reported outcome measures (PROMs): TNO-AZL Preschool children Quality Of Life (TAPQOL) or Pediatric Quality of Life Inventory for Children (PedsQL). The PROMs were completed before and discussed during outpatient consultations. The adaptation rate—the proportion of patients/parents who were invited and completed at least one PROM—was calculated. Reported HRQoL scores of CKD patients were compared to the general population. (3) Results: In total, 142 patients (proxy- and self-report) were invited, 112 patients completed at least one PROM (adaptation rate 79%). Patients (n = 84 with informed consent for scientific use) with CKD reported lower HRQoL and HRQoL was more often impaired compared to the general Dutch population. (4) Conclusions: The implementation of KLIK was successful and its use is feasible for daily care. Using KLIK, HRQoL problems can be easily identified and monitored.

Long-term social outcome after pediatric kidney transplantation: a single-center experience

BACKGROUND

Patient and graft survival rates after pediatric kidney transplantation have improved recently. Therefore, the quality of life or social outcome after kidney transplantation has become important for patients and their families.

METHODS

Patients who underwent kidney transplantation at < 18 years old and were observed for > 10 years were included in this study. The median age at first kidney transplantation was 9.2 (interquartile range [IQR] = 5.6-13.0) years; there were 56 males and 50 females. The median age at last follow-up was 29.9 (IQR = 22.2-36.0) years. We evaluated the patients' renal function, growth, professional status, and marital status at the last follow-up.

RESULTS

The percentage of functioning grafts at the last follow-up was 81.1%; 73 patients (68.9%) had a first graft. The mean estimated GFR was 51.0 ± 20.5 mL/min/1.73 m². Twenty patients received dialysis for graft failure. The mean final heights of the males and females were 158.1 ± 9.2 cm (- 2.2 standard deviations) and 149.1 ± 6.4 cm (- 1.7 standard deviations), respectively. Excluding 23 students, 63 patients (75.9%) were employed. Office worker was the most common profession. Twelve patients (14.5%) were unemployed. Of patients > 20 years old, 14 (16.7%), three males and 11 females, were married. Five females had one child each.

CONCLUSIONS

The graft survival rate was favorable. The final height was short, particularly in male. The rate of employment was relatively high. The rate of marriage and having children were still low. Improving the social outcome is an important problem after pediatric kidney transplantation.

Caregiver burden in pediatric dialysis: application of the Paediatric Renal Caregiver Burden Scale

BACKGROUND

Caring for a child with kidney failure on dialysis profoundly impacts caregivers' lives, yet the depth of this burden is not well understood. The Paediatric Renal Caregiver Burden Scale (PR-CBS) is a recently validated instrument used to measure caregiver burden in this population.

METHODS

We performed a cross-sectional study of caregiver burden for caregivers of children with kidney failure receiving dialysis at three pediatric centers. Caregivers completed the PR-CBS instrument as part of a larger qualitative study of caregiver experience. We performed descriptive statistics. T-tests were used to examine differences between dialysis modality and within key demographics. Multivariate linear regression was utilized to assess associations between significant factors and total score.

RESULTS

Ten caregivers of children receiving peritoneal dialysis (PD) and 21 receiving hemodialysis (HD) participated. Total burden score and mean score for every domain was higher for caregivers of children on HD compared to PD. PR-CBS score was significantly associated with younger child age and married status in caregivers. In adjusted multivariate analysis, dialysis modality and married marital status were significantly associated with PR-CBS score.

CONCLUSIONS

This study found that dialysis caregivers experience significant caregiver burden and demonstrates the utility of the PR-CBS in an American population. We found higher burdens among HD caregivers, younger children, and married caregivers. While these findings must be replicated on a larger scale, they suggest possible areas for targeted interventions to improve the quality of life of children with kidney failure and their families.

Growth in children on kidney replacement therapy: a review of data from patient registries

Growth retardation is a major complication in children with chronic kidney disease (CKD) and on kidney replacement therapy (KRT). Conversely, better growth in childhood CKD is associated with an improvement in several hard morbidity-mortality endpoints. Data from pediatric international registries has demonstrated that improvements in the overall conservative management of CKD, the search for optimal dialysis, and advances in immunosuppression and kidney transplant techniques have led to a significant improvement of final height over time. Infancy still remains a critical period for adequate linear growth, and the loss of stature during the first years of life influences final height. Preliminary new original data from the European Society for Paediatric Nephrology/European Renal Association-European Dialysis and Transplant Association (ESPN/ERA-EDTA) Registry confirm an association between the final height and the height attained at 2 years in children on KRT.

Long-term psychosocial outcomes of adults transplanted in childhood: A social work perspective

While much research exists regarding medical outcomes for pediatric end stage renal disease (ESRD) populations and for adults receiving dialysis or kidney transplant, the understanding of long-term psychosocial outcomes for individuals diagnosed with ESRD or transplanted in childhood remains limited. A literature review was undertaken by two social work researchers to identify relationship, education, employment, and quality of life (QOL) outcomes for this population utilizing PUBMED and PsycInfo databases. Inconsistencies in the MeSH terms and keywords used across the relevant articles were noted. The impact of transplantation in childhood is significant across multiple facets of social development including but not limited to peer/intimate relationships, education and employment and QOL, and overall well-being. When compared to healthy peers, those with ESRD were delayed in all areas of social development. While improvements in psychosocial outcomes have occurred alongside improved graft and patient survival, more focused longitudinal and qualitative inquiry is needed. Partnerships are needed across disciplines and across those caring for different age cohorts in pediatric, adult nephrology, and transplant practices.

Perspectives on life participation by young adults with chronic kidney disease: an interview study

OBJECTIVE

To describe the perspectives on life participation by young adults with childhood-onset chronic kidney disease (CKD).

DESIGN

Semi-structured interviews; thematic analysis.

SETTING

Multiple centres across six countries (Australia, Canada, India, UK, USA and New Zealand).

PARTICIPANTS

Thirty young adults aged 18 to 35 years diagnosed with CKD during childhood.

RESULTS

We identified six themes: struggling with daily restrictions (debilitating symptoms and side effects, giving up valued activities, impossible to attend school and work, trapped in a medicalised life, overprotected by adults and cautious to avoid health risks); lagging and falling behind (delayed independence, failing to keep up with peers and socially inept); defeated and hopeless (incapacitated by worry, an uncertain and bleak future, unworthy of relationships and low self-esteem and shame); reorienting plans and goals (focussing on the day-to-day, planning parenthood and forward and flexible planning); immersing oneself in normal activities (refusing to miss out, finding enjoyment, determined to do what peers do and being present at social events); and striving to reach potential and seizing opportunities (encouragement from others, motivated by the illness, establishing new career goals and grateful for opportunities).

CONCLUSIONS

Young adults encounter lifestyle limitations and missed school and social opportunities as a consequence of developing CKD during childhood and as a consequence lack confidence and social skills, are uncertain of the future, and feel vulnerable. Some re-adjust their goals and become more determined to participate in 'normal' activities to avoid missing out. Strategies are needed to improve life participation in young adult 'graduates' of childhood CKD and thereby strengthen their mental and social well-being and enhance their overall health.

Developing Consensus-Based Outcome Domains for Trials in Children and Adolescents With CKD: An International Delphi Survey

RATIONALE & OBJECTIVE

The inconsistency in outcomes reported and lack of patient-reported outcomes across trials in children with chronic kidney disease (CKD) limits shared decision making. As part of the Standardized Outcomes in Nephrology (SONG)-Kids initiative, we aimed to generate a consensus-based prioritized list of critically important outcomes to be reported in all trials in children with CKD.

STUDY DESIGN

An online 2-round Delphi survey in English, French, and Hindi languages.

SETTINGS & PARTICIPANTS

Patients (aged 8-21 years), caregivers/family, and health care professionals (HCPs) rated the importance of outcomes using a 9-point Likert scale (7-9 indicating critical importance) and completed a Best-Worst Scale.

ANALYTICAL APPROACH

We assessed the absolute and relative importance of outcomes. Comments were analyzed thematically.

RESULTS

557 participants (72 [13%] patients, 132 [24%] caregivers, and 353 [63%] HCPs) from 48 countries completed round 1 and 312 (56%) participants (28 [40%] patients, 64 [46%] caregivers, and 220 [56%] HCPs) completed round 2. Five outcomes were common in the top 10 for each group: mortality, kidney function, life participation, blood pressure, and infection. Caregivers and HCPs rated cardiovascular disease higher than patients. Patients gave lower ratings to all outcomes compared with caregivers/HCPs except they rated life participation (round 2 mean difference, 0.1), academic performance (0.1), mobility (0.4), and ability to travel (0.4) higher than caregivers and rated ability to travel (0.4) higher than HCPs. We identified 3 themes: alleviating disease and treatment burden, focusing on the whole child, and resolving fluctuating and conflicting goals.

LIMITATIONS

Most participants completed the survey in English.

CONCLUSIONS

Mortality, life participation, kidney function, and blood pressure were consistently highly prioritized by patients, caregivers, and HCPs. Patients gave higher priority to some lifestyle-related outcomes compared with caregivers/HCPs. Establishing critically important outcomes for all trials in children with CKD may improve consistent reporting of survival, kidney health, and clinical and life impact outcomes that are meaningful for decision making.

Establishing core outcome domains in pediatric kidney disease: report of the Standardized Outcomes in Nephrology-Children and Adolescents (SONG-KIDS) consensus workshops

Trials in children with chronic kidney disease do not consistently report outcomes that are critically important to patients and caregivers. This can diminish the relevance and reliability of evidence for decision making, limiting the implementation of results into practice and policy. As part of the Standardized Outcomes in Nephrology-Children and Adolescents (SONG-Kids) initiative, we convened 2 consensus workshops in San Diego, California (7 patients, 24 caregivers, 43 health professionals) and Melbourne, Australia (7 patients, 23 caregivers, 49 health professionals). This report summarizes the discussions on the identification and implementation of the SONG-Kids core outcomes set. Four themes were identified; survival and life participation are common high priority goals, capturing the whole child and family, ensuring broad relevance across the patient journey, and requiring feasible and valid measures. Stakeholders supported the inclusion of mortality, infection, life participation, and kidney function as the core outcomes domains for children with chronic kidney disease.

A longitudinal examination of parent-reported emotional-behavioral functioning of children with mild to moderate chronic kidney disease

BACKGROUND

Children with mild to moderate chronic kidney disease (CKD) are at increased risk for deficits in neurocognition. Less is known about how CKD affects emotional-behavioral functioning in this population.

METHODS

Parent ratings of emotional-behavioral functioning at baseline and over time were examined for 845 children with mild to moderate CKD using the Behavior Assessment System for Children, Second Edition Parent Rating Scales (BASC-2 PRS). Associations with demographic and disease-related predictors were also examined.

RESULTS

Children with mild to moderate CKD had parent-reported emotional-behavioral functioning largely within normal limits, at baseline and over time. The proportion with T-scores at least 1 SD above the mean was 24% for Internalizing Problems and 28% for Attention Problems. A greater proportion of participants scored lower than expected (worse) on scales measuring adaptive skills (25%). Persistent hypertension predicted attention problems (β = 1.59, 95% CI = 0.24 to 2.94, p < 0.02) and suggested worse behavioral symptoms (β = 1.36, 95% CI = - 0.01 to 2.73, p = 0.05). Participants with proteinuria at baseline, but not at follow-up, had fewer attention problems than participants whose proteinuria had not resolved (β = - 3.48, CI = - 6.79 to - 0.17, p < 0.04). Glomerular diagnosis was related to fewer (β = - 2.68, 95% CI = - 4.93 to - 0.42, p < 0.02) internalizing problems.

CONCLUSIONS

Although children with CKD generally have average emotional-behavioral parent ratings, a notable percentage of the population may be at risk for problems with attention and adaptive behavior. Providers working with this population should facilitate psychosocial referrals when indicated.

Long-term consequences of renal insufficiency in children: lessons learned from the Dutch LERIC study

Few data exist on the prospects in adulthood for children on chronic renal replacement therapy (RRT). This article summarizes the results of a comprehensive Dutch long-term follow-up study performed in 2000 and 2010 of patients with RRT onset at age <15 years between 1972 and 1992. After a median of 25.5 RRT years, patients had stayed 23% of RRT time on dialysis. We observed a 30 times greater mortality risk compared with age-matched peers with cardiovascular disease (CVD) as the main cause of death during 1972-2000 and infections during 2000-10. The observed shift towards infections was associated with more RRT time with a graft and receiving a stricter CVD protective treatment. For patients >40 years of age, motor disabilities affecting routine activities, skin cancer and severe fatigue were the most disabling sequelae. After 30 years of transplantation, 41% of the survivors had developed cancer, a life-threatening form of squamous cell skin carcinoma being most prevalent. Important delays in autonomy development and educational attainment and a relatively high level of unemployment were observed. Transplanted patients reported a good mental and physical quality of life, but the latter tended to decrease over time. A long period of dialysis was associated with all adverse somatic and psychosocial outcomes. Paediatric nephrologists should aim for transplantation at the earliest possible time and focus on autonomy and educational attainment. Nephrologists should focus on strict CVD prevention, adjustment of immunosuppression to the lowest possible dose and surveillance of malignancy-associated viral infections in patients with childhood end-stage renal disease.

Children's experiences and expectations of kidney transplantation: A qualitative interview study

AIM

Kidney transplantation offers improved quality of life and life expectancy compared with dialysis for children. This study aims to understand the experiences and expectations of children during the kidney transplantation process to inform clinical care.

METHODS

Face-to-face, semi-structured interviews were conducted with 13 children and adolescents aged between 7 and 17 years in New Zealand who had received a kidney transplantation. Findings were conceptualized using thematic analysis with inductive coding.

RESULTS

Three major themes were identified: transplant as the goal (the only real treatment and escaping dialysis); dealing with negative emotions (coping with anxiety and fear, guilt for siblings and burden of parent as donor); and enhancing understanding and knowledge (individualised education and reassurance from peer support).

CONCLUSION

Children and adolescents view transplantation as freedom from dialysis and return to a more normal life. Children focus on the positive aspects of transplantation to reduce anxiety and be reassured in the face of uncertainty. Complex emotions arise when thinking about their donor. Children recognize transplantation is not a return to full health and actively seek out ways to self-manage their care, while remaining anxious about their future.

Protocol for psychosocial screening of adolescents and young adults with chronic illness

BACKGROUND

One in five adolescents and young adults (AYA) has a chronic health condition necessitating on-going engagement with healthcare systems. Despite increasing prevalence there remains limited understanding of the burden of illness they experience. Living with a chronic illness can challenge healthy adolescent development, with the unique health and developmental issues affecting AYA requiring different responses from the healthcare system.

AIMS

To examine and compare the burden of illness in this group across a large range of chronic health conditions.

METHODS

In a dedicated health service for AYA aged 15-25 years with chronic health conditions, (13-25 years for those with substance use issues) we detail a protocol where demographics, general health, disease-specific indicators and comprehensive psychosocial variables will be collected. The health conditions include chronic gastrointestinal disease, cystic fibrosis, chronic rheumatic disease, phenylketonuria, craniomaxillofacial deformities, renal transplant patients and problematic substance use. Results will be compared to AYA without chronic illness and AYA with diabetes.

RESULTS

This protocol outlines a comprehensive screening study for AYA with a large range of chronic health conditions, inclusive of medical, mental health, impairment and quality of life variables. It will inform service planning and provide a foundation upon which allied health service requirements (e.g. psychology) can be based. Whilst currently cross-sectional we anticipate further utility in broadening outcomes to include non-physical illness-related constructs.

CONCLUSIONS

The commonalities and differences between conditions will be examined to facilitate efficiencies of scale for systems and supports. Further iterations including quantifying access to allied health services will facilitate studying the impact of such interventions on treatment adherence and improving psychosocial functioning, quality of life and disease outcomes.

Mortality Risks among Various Primary Renal Diseases in Children and Adolescents on Chronic Dialysis

There is little information available on the association between primary renal disease (PRD) and long-term mortality in the pediatric dialysis population. The objective of this study was to explore mortality risks in children and adolescents on chronic dialysis, specifically focused on the risk of various PRDs. The study cohort included children and adolescents with end-stage renal disease (ESRD) (aged < 20 years) who had received dialysis for at least 90 days between 2000 and 2014 and were identified from Taiwan's National Health Insurance medical claims. A total of 530 children and adolescents were included in the study. The median age of the included patients was 13.6 years and 305 (57.5%) patients were males. One hundred and seven patients died during the follow-up period and the median survival time was 6.0 years. Mortality was highest in the youngest patients. For patients with the following PRDs, mortality was significantly higher than that in patients with primary glomerulonephritis: secondary glomerulonephritis (adjusted hazard ratio (aHR): 2.50; 95% confidence interval (CI): 1.03⁻6.08), urologic disorder (aHR: 4.77; 95% CI: 1.69⁻13.46), and metabolic diseases (aHR: 5.57; 95% CI: 1.84⁻16.85). Several kinds of PRDs appear to have high mortality risks in the pediatric dialysis population. These differences in mortality risk highlight the importance of the focused clinical management of these high-risk subgroups.

[Self-Management Experiences of the Adolescents with Chronic Kidney Disease]

PURPOSE

The aim of this study was to develop a substantive theory on self-management conducted by the adolescents with chronic kidney disease from their lived experience.

METHODS

Data was collected through in-depth interviews from May to December in 2015 with thirteen adolescents with chronic kidney disease. The data collected were analyzed on the basis of Strauss and Corbin's grounded theory.

RESULTS

The core of the category found in this study was "overcoming the unstable sense of self-control and integrating disease experience into their life". The causal conditions triggering the central phenomenon were "restriction in daily life" and "manifestation and aggravation of symptom". The central phenomenon in the experience of self-management within the adolescents with chronic kidney disease was "unstable sense of self control". The intervening condition for unstable self control were "micro system support" and "motivational resources". This study found that the adolescents with chronic kidney disease followed a series of strategies when they faced the central phenomenon, including; passive coping, reappraisal of illness, active coping, compliance with treatment, controlling physical activity, and adjusting school life. With these strategic approaches, the adolescents with chronic kidney disease could maintain their active lifestyles and achieve their health behaviors. The process of self-management by these adolescents passed through four phases; limited experience caused by diseases, effort for normalization, reorganizing their daily lives, and integration with daily lives and self-management.

CONCLUSION

This Study explored the process and experience of self-management of adolescents with chronic kidney disease. These findings can be used for basis for developing substantive theory and nursing intervention strategy for adolescents with chronic kidney diseases.

Children on dialysis as well as renal transplanted children report severely impaired health-related quality of life

Objectives

To assess health-related quality of life (HRQoL) across three renal replacement therapy modalities (preemptive transplant, non-preemptive transplant, and dialysis) in comparison with the healthy norm and other chronic health conditions, and to explore related patient factors.

Study design

All prevalent end-stage renal disease (ESRD) patients aged 8–18 years who spent at least 6 months on their current treatment modality in the Netherlands, Belgium, and part of Germany were approached to complete the Pediatric Quality of Life Inventory 4.0 (PedsQL™) questionnaire. We determined the differences between groups on PedsQL™ mean scores, the proportion of children with an impaired HRQoL (≥ 1 SD lower than the healthy norm), the proportion of problems on individual items of the PedsQL™, and the effect of time on current treatment. Linear regression models were used to explore determinants of HRQoL.

Results

192 out of 278 patients (20% preemptive transplant, 58% non-preemptive transplant, 22% dialysis) filled in the PedsQL™ (response rate 69%). Independent of treatment modality, patients had significantly lower mean scores and consequently higher proportions of impaired HRQoL on almost all domains compared to the healthy norm and other chronic health conditions. Patients with a preemptive transplant only reported higher scores on physical health compared to the other treatment modalities. Having comorbidities was the most important determinant associated with lower HRQoL scores.

Conclusion

Dialysis and renal transplantation both have a severe impact on the HRQoL of children with ESRD. Physicians should be aware of this continuous burden. Furthermore, to develop tailored interventions for children with ESRD, qualitative studies are needed to gain more insight in the determinants of HRQoL in the different treatment modalities.

Quality of life and duration of hemodialysis in patients with chronic kidney disease (CKD): a cross-sectional study

Abstract Introduction: Quality of life (QoL) of hemodialysis patients is a major evaluative marker currently measured, while treatment time is a clinical determinant associated with impaired QOL. Objective: To evaluate QOL in individuals undergoing hemodialysis (HD) considering treatment time and the presence of comorbidities. Methods: A cross-sectional study conducted in the hemodialysis unit of the Hospital das Clínicas da Universidade Federal de Pernambuco (HC-UFPE). We studied patients with Chronic Kidney Disease (CKD) of both genders over the age of 18 years, at any level of education and undergoing HD for at least 6 months. We evaluated the demographic/socioeconomic and clinical data, followed by application of the quality of life questionnaire (KDQOL-SF). Results: Participants were 47 patients with a mean age of 50.94 ± 13.33 years, 55.3% were male and average treatment time of 57.35 ± 61.46 months. Hypertension (59.6%) was the most frequent underlying disease. According to the responses obtained through the KDQOL-SF, the situation at work and physical limitation scored worse. Sexual function (85.83) and encouragement by the team had the best performance. There were no differences in dimensions of questionnaire and treatment time. Conclusion: The presence of comorbidities and HD duration were not found to be possible factors for changing QoL in this study. However, we suggest that future studies evaluate other factors such as laboratory, emotional and functional data to check for changes in QoL in these patients related to HD duration.

What has changed in the prevalence of hypertension in dialyzed children during the last decade?

BACKGROUND

Hypertension very often accompanies progression of chronic kidney disease (CKD) in children. A cross-sectional analysis of hypertension prevalence in dialyzed children in Poland was designed with a comparison with the data previously recorded 10 years earlier.

METHODS

Two cohorts of children were analyzed: 59 subjects dialyzed in 2013, and 134 children from the previous study performed in 2003 that were reevaluated according to the current methodology. The incidence of hypertension (defined by SDS of sBP or dBP >1.64), clinical data, medical history, dialysis modalities and selected biochemical parameters of dialysis adequacy were analyzed.

RESULTS

The prevalence of hypertension increased from 64% in 2003 to 78% in 2013. The efficacy of antihypertensive treatment remained unsatisfactory (61% proper BP control). Preservation of residual urine output and strict fluid balance may prevent development of hypertension in children on dialysis.

CONCLUSIONS

Despite the higher awareness of hypertension and its complications in dialyzed children, the incidence of this entity has increased during the last decade, with the percentage of undertreated patients comparable to that observed 10 years ago. Thus, more attention should be paid to therapy efficacy in this population to prevent further damage to the cardiovascular system and to decrease morbidity.

Health-related quality of life in patients with pediatric onset of end-stage renal disease: state of the art and recommendations for clinical practice

Health-related quality of life (HRQoL) is increasingly recognized as a key outcome in both clinical and research settings in the pediatric population with end-stage renal disease (ESRD). This review aims to: (1) summarize the current knowledge on HRQoL and socioprofessional outcomes and (2) provide strategies for incorporation of HRQoL assessment into clinical practice. Studies report that pediatric patients with ESRD have significantly lower HRQoL scores compared with children with other chronic diseases. Patients treated by dialysis are at particularly high risk for impaired HRQoL. Furthermore, patients more often have impaired neurocognitive functioning and lower academic achievement. Important determinants of impaired HRQoL include medical factors (i.e., receiving dialysis, disabling comorbidities, cosmetic side effects, stunted growth), sociodemographic factors (i.e., female gender, non-Western background) and psychosocial factors (i.e., noneffective coping strategies). Contrary to the situation in childhood, adult survivors of pediatric ESRD report a normal mental HRQoL. Despite this subjective feeling of well-being, these patients have on average experienced significantly more difficulties in completing their education, developing intimate relationships, and securing employment. Several medical and psychosocial strategies may potentially improve HRQoL in children with ESRD. Regular assessment of HRQoL and neurocognitive functioning in order to identify areas in which therapies and interventions may be required should be part of standard clinical care.

Disease control via intensified lipoprotein apheresis in three siblings with familial hypercholesterolemia

BACKGROUND

Familial hypercholesterolemia (FH), the prevalent monogenic form of hypercholesterolemia, carries the risk of premature coronary heart disease. Lipoprotein-apheresis is established in children with severe dyslipidemia. We present 3 siblings with a negative/negative residual low-density lipoprotein (LDL) receptor mutation (p.Trp577Arg), unresponsive to drug treatment.

OBJECTIVE

Intensified lipoprotein-apheresis is well tolerated and results in permanently low lipid values without harming the health-related quality of life in children.

METHODS

Three homozygous FH siblings, aged 7-13 years, had been treated with statins and ezetimibe for 12 months but still showed highly elevated low-density lipoprotein cholesterol (LDL-C) plasma concentrations. They were started on double-filtration plasmapheresis that was subsequently intensified according to plasma lipid levels.

RESULTS

Each lipoprotein apheresis session reduced LDL-C concentration by 66% to 70%. Treated plasma volume was doubled after 6 months due to a sustained rebound of LDL-C between sessions. However, the rebound remained unchanged. Only an increase in frequency of sessions to every 3 to 4 days resulted in acceptable pre-treatment LDL-C concentrations (Cmax). Neither cessation of statins nor reduction of plasma exchange volume to 1.5 fold in follow-up influenced Cmax. Intensified therapy did not harm health-related quality of life as assessed by PedsQL and was well tolerated.

CONCLUSIONS

In pediatric FH patients unresponsive to drug treatment, intensified lipoprotein apheresis can normalize plasma lipid levels. Apparently, treatment frequency rather than volume has greater influence on its efficacy. The potential burden of intensified therapy to daily life has to be regarded. Serum lipid levels in FH should be normalized to minimize cardiovascular risk.

Standardised Outcomes in Nephrology-Children and Adolescents (SONG-Kids): a protocol for establishing a core outcome set for children with chronic kidney disease

Background

Children with chronic kidney disease (CKD), requiring dialysis or kidney transplantation, have a mortality rate of up to 30-fold higher than the general aged-matched population, and severely impaired quality of life. Symptoms such as fatigue and pain are prevalent and debilitating. Children with CKD are at risk of cognitive impairment, and poorer educational, vocational, and psychosocial outcomes compared with their well peers, which have consequences through to adulthood. Treatment regimens for children with CKD are long-term, complex, and highly intrusive. While many trials have been conducted to improve outcomes in children with CKD, the outcomes measured and reported are often not relevant to patients and clinicians, and are highly variable. These problems can diminish the value of trials as a means to improve the lives of children with CKD. The Standardised Outcomes in Nephrology—Children and Adolescents (SONG-Kids) study aims to develop a core outcome set for trials in children and adolescents with any stage of CKD that is based on the shared priorities of all stakeholders.

Methods/Design

SONG-Kids involves five phases: a systematic review to identify outcomes (both domains and measures) that have been reported in randomised controlled trials involving children aged up to 21 years with CKD; focus groups (using nominal group technique) with adolescent patients and caregivers of paediatric patients (all ages) to identify outcomes that are relevant and important to patients and their family and the reasons for their choices; semistructured key informant interviews with health professionals involved in the care of children with CKD to ascertain their views on establishing core outcomes in paediatric nephrology; an international three-round online Delphi survey with patients, caregivers, clinicians, researchers, policy-makers, and members from industry to develop consensus on important outcome domains; and a stakeholder workshop to review and finalise the set of core outcome domains for trials in children with CKD (including nondialysis-dependent, dialysis, and kidney transplantation).

Discussion

Establishing a core outcome set to be reported in all trials conducted in children with any stage of CKD will enhance the relevance, transparency, and impact of research to improve the lives of children and adolescents with CKD.

Update on Ethical Issues in Pediatric Dialysis: Has Pediatric Dialysis Become Morally Obligatory?

Improvements in pediatric dialysis over the past 50 years have made the decision to proceed with dialysis straightforward for the majority of pediatric patients. For certain groups, however, such as children with multiple comorbid conditions, children and families with few social and economic resources, and neonates and infants, the decision of whether to proceed with dialysis remains much more controversial. In this review, we will examine the best available data regarding the outcomes of dialysis in these populations and analyze the important ethical considerations that should guide decisions regarding dialysis for these patients. We conclude that providers must continue to follow a nuanced and individualized approach in decision making for each child and to recognize that, regardless of the decision reached about dialysis, there is a continued duty to care for patients and families to maximize the remaining quality of their lives.

Impact of Renal Replacement Therapy in Childhood on Long-Term Socioprofessional Outcomes: A 30-year Follow-Up Study

OBJECTIVE

To evaluate socioprofessional outcomes after 30 years of renal replacement therapy (RRT) and explore predictors of these outcomes.

STUDY DESIGN

The cohort comprised all Dutch patients, born before 1979, who started RRT at age <15 years in 1972-1992. Outcomes including family life, educational attainment, and professional life were obtained in 2000 and 2010 in 80 out of 152 survivors. Participants also completed the Course of Life Questionnaire in 2000, which retrospectively assessed the achievement of developmental milestones while growing up. Socioprofessional outcomes in 2010 were compared with the age-matched general population and with outcomes obtained in 2000. Logistic regression analysis was performed to identify determinants of socioprofessional outcomes.

RESULTS

Mean age and time on RRT in 2010 were 40.6 years (range 32.1-52.4) and 28.9 years (range 18.1-39.7), respectively. Patients were less likely to be employed (62.5% vs 81.0%) and have children (28.8% vs 64.8%) compared with the age-matched general population. Comorbidities, dialysis, short stature, and fewer milestones on autonomy were associated with adverse outcomes. Compared with 2000, in 2010 more patients lived with a partner (68.8% vs 43.0%), and more patients had completed a high level educational degree (22.5% vs 13.9%). However, more patients were unable to work on medical grounds in 2010 (36.3% vs 16.3%).

CONCLUSIONS

Survivors of pediatric end-stage renal disease may gain social autonomy and optimal educational attainment at an older age compared with their general population counterparts. Awareness among health care professionals of the potential of these children and tailored psychosocial interventions might improve socioprofessional development.

Explaining the quality of life of organ transplant patients by using crisis theory

CONTEXT

Ubiquitous findings regarding the quality of life (QOL) of transplant patients have yet to be explained from a theoretical perspective.

OBJECTIVE

To investigate transplant patients' QOL by using the conceptual framework of crisis theory.

DESIGN

Cross-sectional study to explore differences in transplant patients' experiences of stress, coping, and QOL. Regression analysis was used to test crisis theory in relation to QOL, stress, and coping.

PARTICIPANTS

A total of 226 participants representing transplant candidates, transplant recipients, and nontransplant individuals participated via survey-based data collection.

RESULTS

Results showed that transplant candidates experience lower QOL than transplant recipients and nontransplant individuals. No significant differences were detected regarding stress levels or coping styles. Stress made a significant contribution to patients' QOL.

CONCLUSIONS

Current findings suggest important QOL benefits of organ transplant. Using a theoretical model is an effective way to investigate the QOL of people experiencing chronic illness such as end-stage organ failure. Further investigation is required to reach a conclusive understanding of the complex interaction between transplant patients' QOL, stress, and coping.
