Quality of life of adolescents with end-stage renal disease and kidney transplant

Health-related quality of life for pediatric patients with end-stage kidney disease: A systematic review and meta-analysis of the Pediatric Quality of Life Inventory (PedsQL)

INTRODUCTION

Health-related quality of life (HRQoL) studies demonstrate the impact of end-stage renal disease (ESRD) on the physical and psychosocial development of children. While several instruments are used to measure HRQoL, few have standardized domains specific to pediatric ESRD. This review examines current evidence on self and proxy-reported HRQoL among pediatric patients with ESRD, based on the Pediatric Quality of Life Inventory (PedsQL) questionnaires.

METHODS

Following PRISMA guidelines, we conducted a systematic review and meta-analysis on HRQoL using the PedsQL 4.0 Generic Core Scale (GCS) and the PedsQL 3.0 ESRD Module among 5- to 18-year-old patients. We queried PubMed, Embase, Web of Science, CINAHL, and Cochrane databases. Retrospective, case-controlled, and cross-sectional studies using PedsQL were included.

FINDINGS

Of 435 identified studies, 14 met inclusion criteria administered in several countries. Meta-analysis demonstrated a significantly higher total HRQoL for healthy patients over those with ESRD (SMD:1.44 [95% CI: 0.78-2.09]) across all dimensional scores. In addition, kidney transplant patients reported a significantly higher HRQoL than those on dialysis (PedsQL GCS, SMD: 0.33 [95% CI: 0.14-0.53]) and (PedsQL ESRD, SMD: 0.65 [95% CI: 0.39-0.90]) concordant with parent-proxy reports.

DISCUSSION

Patients with ESRD reported lower HRQoL in physical and psychosocial domains compared with healthy controls, while transplant and peritoneal dialysis patients reported better HRQoL than those on hemodialysis. This analysis demonstrates the need to identify dimensions of impaired functioning and produce congruent clinical interventions. Further research on the impact of individual comorbidities in HRQoL is necessary for developing comprehensive, integrated, and holistic treatment programs.

Depression and health-related quality of life in adolescents and young adults with childhood-onset end-stage kidney disease: a multicenter study in Japan

BACKGROUND

Patient survival and physical outcomes among children with end-stage kidney disease (ESKD) have significantly improved, and recent research has focused on long-term depression symptoms and health-related quality of life (HRQOL). However, no studies have been conducted among adolescents and young adults with childhood-onset ESKD in Japan.

METHODS

This multicenter study included 45 adolescents and young adults aged 16-39 years who developed ESKD at age < 20 years. Depression symptoms were measured using the Beck Depression Inventory (BDI)-II. The Short Form-36 Health Survey (SF-36) was used to assess HRQOL. Factors associated with depression and HRQOL were analyzed.

RESULTS

Depression (BDI-II score ≥ 14) was observed in 13 (29%) patients. Patient's SF-36 physical component summary (PCS) and mental component summary (MCS) scores were comparable with those for the general population. Lower estimated glomerular filtration rate, higher BDI-II scores, and lower body mass index were associated with lower PCS scores. BDI-II scores were negatively correlated with MCS scores. We observed a trend that unemployment was associated with lower MCS scores.

CONCLUSIONS

Depression is frequently observed among adolescents and young adults with childhood-onset ESKD. Regular screening for psychosocial concerns, maintaining stable graft functions, and achieving optimal nutritional status may contribute to improved well-being among these patients.

Health-related quality of life in Egyptian children with nephrotic syndrome

PURPOSE

This research aimed to evaluate Quality of life (QoL) in Egyptian children with idiopathic Nephrotic syndrome (INS) in comparison to healthy children and children with chronic non-renal illnesses.

METHODS

In this questionnaire-based study, 300 children were included, 100 with INS and 2 matched control groups: healthy group, and chronic non-renal illness group. QoL was assessed using the Pediatric Quality of Life Inventory (PedsQL™ 4.0 Generic Core Scales) and the Generic Children's QoL Measure (GCQ).

RESULTS

All mean scores of PedsQL domains in INS group were significantly higher than chronic non-renal illness group and significantly lower than the healthy control group (p =  < 0.001) for all and similar results reported also regarding GCQ scores in INS compared to diseased (p = 0.02) and healthy controls (p = 0.006). Steroid-resistant NS group had lowest scores in all domains (p =  < 0.001) compared to other clinical phenotypes of NS group. The long duration of illness, higher number of relapses, high cumulative steroid dose, and high number of medications used were associated with lower PedsQL and GCQ scores (p < 0.001 for all) CONCLUSION: This is the first study to asses QoL in Egyptian children with INS and correlates QoL scores to clinical phenotypes and complications of the disease. Egyptian children with INS need strenuous efforts from pediatricians and psychiatrists to improve QoL. Both PedsQL™ 4.0 scale and GCQ are simple, convenient, and can be used in daily clinical practice to asses QoL in children with NS.

Assessment of Quality of Life among Children with End-Stage Renal Disease: A Cross-Sectional Study

Background

Measuring health-related quality of life is considered an important outcome indicator in evaluating health-care interventions and treatments and in understanding the burden of diseases.

Objectives

This study aimed at assessing quality of life among children with end-stage renal disease, either undergoing hemodialysis or had renal transplantation therapy and comparing it with healthy controls.

Methods

A cross-sectional study was conducted between December 2016 and May 2017 in Abo El-Reesh Pediatric Hospital using parent/child reports of generic module for QoL assessment: PedsQL^TM Inventory version 4 for both cases and controls. Disease-specific module: PedsQL^TM ESRD version 3 was used for ESRD cases. 55 ESRD cases and 86 controls were enrolled in the study.

Results

Statistically significant difference between ESRD cases and controls regarding all aspects of QoL was found; total QoL mean score was 58.4 ± 15.3 and 86.8 ± 10 among cases and controls, respectively. All individual QoL domains were significantly worse in ESRD cases. Transplantation group had better Spearman's correlation between child and parents' scores which showed significant positive moderate correlation.

Conclusions

ESRD and its treatment modalities are affecting negatively all aspects of quality of life; incorporating QoL assessment and management is highly recommended.

EQ-5D-Y for the assessment of health-related quality of life among Taiwanese youth with mild-to-moderate chronic kidney disease

Objective

To assess if health-related quality of life (HRQOL) of children with chronic kidney disease (CKD) and different comorbid conditions can be identified based on the EQ-5D child-friendly version (EQ-5D-Y).

Design

Prospective cross-sectional study.

Setting

A tertiary care medical center in Taiwan.

Study participants

All CKD patients aged 7-18 years treated at the center between May 2014 and December 2016.

Main Outcome Measures

HRQOL assessment was done using EQ-5D-Y. Spearman correlation tests were used for construct validity of the traditional Chinese version of EQ-5D-Y. Test-retest reliability was determined through Cohen's kappa values and intraclass correlation coefficients (ICC). Laboratory results and CKD-related morbid conditions were ascertained and assessed their associations with HRQOL score using multivariate linear regression.

Results

Of 68 participants, 53 of them completed two HRQOL assessments of HRQOL at least 6-month. Cross-sectional analysis revealed fair to moderate correlations between EQ visual analogue score and patient characteristics. Older children at assessment (P < 0.01), girls (P = 0.03) and presence of mineral bone disorders had a significantly negative impact on HRQOL. Children self-reported EQ-5D-Y dimensions were found to be fairly to highly reliable (kappa = 0.2 to 0.8), except for 'pain/discomfort' and 'anxiety/depression'.

Conclusions

The EQ-5D-Y discriminated among children with different level of CKD-related clinical burden, but the psychometric properties may be limited in some HRQOL dimensions. Further research will need to address factors that may threaten validity and reliability data provided by children and adolescents.

Bioengineering in renal transplantation: technological advances and novel options

End-stage kidney disease (ESKD) is one of the most prevalent diseases in the world with significant morbidity and mortality. Current modes of renal replacement therapy include dialysis and renal transplantation. Although dialysis is an acceptable mode of renal replacement therapy, it does have its shortcomings, which include poorer life expectancy compared with renal transplantation, risk of infections and vascular thrombosis, lack of vascular access and absence of biosynthetic functions of the kidney. Renal transplantation, in contrast, is the preferred option of renal replacement therapy, with improved morbidity and mortality rates and quality of life, compared with dialysis. Renal transplantation, however, may not be available to all patients with ESKD. Some of the key factors limiting the availability and efficiency of renal transplantation include shortage of donor organs and the constant risk of rejection with complications associated with over-immunosuppression respectively. This review focuses chiefly on the potential roles of bioengineering in overcoming limitations in renal transplantation via the development of cell-based bioartificial dialysis devices as bridging options before renal transplantation, and the development of new sources of organs utilizing cell and organ engineering.

Predicting Health Care Utilization and Charges Using a Risk Score for Poor Adherence in Pediatric Kidney Transplant Recipients

Pediatric kidney transplant recipients must follow a complicated regimen of timely adherence to immunosuppressant medication, routine blood work, and medical follow-up visits. Failure to adhere to the recommended regimen can result in medical complications and costly treatment. We developed a novel risk score to identify patients at risk for poor adherence behaviors and evaluated whether it would predict future health care utilization and charges. Our risk stratification score combined three simple pass/fail metrics of adherence derived directly from the electronic health record including standard deviation of immunosuppression drug levels, timely laboratory monitoring, and timely clinic visits as indicated by our clinical protocol. Risk for poor adherence was assessed over a three-month period. Linear regression was used to predict subsequent health care charges and utilization. Greater than 75% of patients had some degree of nonadherence risk during the study period, but there were no significant differences found on any outcomes for the overall score. However, when the individual components of the overall risk score were evaluated independently, patients with tacrolimus drug level standard deviation ≥2 (e.g., a marker of poor adherence) had greater health care utilization (e.g., hospitalizations) and increased total charges. Additionally, patients who did not follow up in clinic at least every 4 months had more ED visits and ED-related charges, but fewer hospitalizations. Regular clinic visits and minimizing drug level variation may deter future costly ED visits and hospitalizations.

Sociodemographic, Psychologic Health, and Lifestyle Outcomes in Young Adults on Renal Replacement Therapy

BACKGROUND AND OBJECTIVES

Young adults receiving RRT face additional challenges in life. The effect of established kidney failure on young adulthood is uncertain. We aimed to establish the psychosocial and lifestyle status of young adults receiving RRT.

DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS

Our study was a systematic review and meta-analysis of 16-30-year olds receiving RRT compared with the general population. We selected randomized, controlled trials; cohort studies; or cross-sectional studies without language restriction and extracted proportions of sociodemographic and lifestyle outcomes or validated psychologic health tests producing quality of life, wellbeing, and self-esteem scores. We undertook random effects meta-analysis.

RESULTS

There were 60 studies with a total of 15,575 participants. Studies were largely single-center cross-sectional studies of those transplanted in childhood. Compared with healthy peers, young adults on RRT had lower quality of life, which was worse for patients on dialysis (seven studies: standardized mean difference, -1.01; 95% confidence interval [95% CI], -1.32 to -0.70) compared with patients with transplants (nine studies: standardized mean difference, -0.42; 95% CI, -0.64 to -0.20). They were more likely to be unemployed (seven studies: relative risk, 1.89; 95% CI, 1.47 to 2.44) and live in the family home (two studies: relative risk, 1.84; 95% CI, 1.40 to 2.43). They were less likely to be married or have a partner (four studies: relative risk, 0.71; 95% CI, 0.53 to 0.95). Higher education (three studies: relative risk, 1.05; 95% CI, 0.73 to 1.51), alcohol abstinence (three studies: relative risk, 1.96; 95% CI, 0.84 to 4.67), and smoking status (two studies: relative risk, 0.72; 95% CI, 0.36 to 1.44) did not differ. Results were limited by high heterogeneity and a small evidence base, biased toward surviving patients.

CONCLUSIONS

Established kidney failure is associated with lower quality of life in young people and limited employment, independence, and relationships compared with healthy peers.

Assessment of physical and psychosocial status of children with ESRD under regular hemodialysis, a single centre experience

BACKGROUND AND OBJECTIVES

Children with end stage renal disease (ESRD) under regular hemodialysis suffer from various health problems that result either from the sequelae of disease itself or its various lines of therapy. The aim of this study is to clarify biodemographic characteristics, common complaints, and physical, and psychosocial status of children with ESRD under regular maintenance hemodialysis.

PATIENTS AND METHODS

This study was conducted on forty children (13 males, 17 females) aged 6-16 years with ESRD under regular hemodialysis, selected from the Pediatric Nephrology Unit at Tanta University Hospitals. Three structured questionnaires were used that measured the biodemographic data of children and their parents, common complaints before and after the onset of hemodialysis, and a physical and psychosocial status assessment sheet comprising of nutritional habits, sleeping patterns, daily physical activities, school achievement, the emotional, behavioral and social aspects of children, and different social relationships.

RESULTS

Most children with ESRD exhibited abnormal nutritional habits, disturbed sleep, decreased physical daily activities, impaired school achievement, and changing emotions and behaviors, and depressed social relationships.

CONCLUSION

Common adverse effects of ESRD and hemodialysis in our center are inadequate nutritional status, abnormal sleep patterns, decreased physical activity, low school achievement, and psychosocial deterioration.

RECOMMENDATIONS

Great efforts on the part of parents, pediatric nephrologists, nurses, psychologist, and school teachers are needed to improve the physical and psychosocial health of dialysis patients and thereby improve their quality of life.

Psychosocial aspects of children and families treated with hemodialysis

INTRODUCTION

The aim of this study was to analyze the selected psychosocial aspects of chronic kidney disease in children treated with hemodialysis (HD).

METHODS

The study included 25 children treated with HD aged 2 to 18 years and their parents. Data concerning the illness and socio-demographic parameters was collected. We used the Paediatric Quality of Life Inventory (PedsQL) for patients and for their parents the PedsQL-proxy version, General Health Questionnaire (GHQ-12), Berlin Social Support Scales (BSSS), and the Caregivers Burden Scale (CBS) to evaluate health-related quality of life (QoL) of HD children and their primary caregivers.

FINDINGS

In the PedsQL test, the QoL of HD children was lower than in healthy children. Children treated with HD assessed their QoL on the PedsQL questionnaire higher than the primary caregivers, on all subscales as well as an overall health-related QoL. Scoring below 2 on the GHQ-12 test was reported in 56% of mothers, which may indicate that psychological symptoms have intensified. There was no correlation between BSSS, CBS, and GHQ-12.

DISCUSSION

The assessment of QoL in pediatric patients would allow for the earliest possible identification of their nonsomatic problems and irregularities. This could, consequently, contribute to improving QoL in both children with chronic kidney disease and their families.

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.

Final Height and Associated Factors in Perinatally HIV-infected Asian Adolescents

We analyzed final height of 273 perinatally HIV-infected Asian adolescents older than 18 years at their last clinic visit. By the World Health Organization child growth reference, 30% were stunted, but by the Thai child growth reference, 19% were stunted. Half of those who were stunted at antiretroviral therapy initiation remained stunted over time. Being male and having a low baseline height-for-age Z score of less than -1.0 were associated with low final height Z score.

Gaining the Patient Reported Outcomes Measurement Information System (PROMIS) perspective in chronic kidney disease: a Midwest Pediatric Nephrology Consortium study

BACKGROUND AND OBJECTIVES

Chronic kidney disease is a persistent chronic health condition commonly seen in pediatric nephrology programs. Our study aims to evaluate the sensitivity of the Patient Reported Outcomes Measurement Information System (PROMIS) pediatric instrument to indicators of disease severity and activity in pediatric chronic kidney disease.

METHODS

This cross sectional study included 233 children 8-17 years old, with chronic kidney disease from 16 participating institutions in North America. Disease activity indicators, including hospitalization in the previous 6 months, edema, and number of medications consumed daily, as well as disease severity indicators of kidney function and coexisting medical conditions were captured. PROMIS domains, including depression, anxiety, social-peer relationships, pain interference, fatigue, mobility, and upper extremity function, were administered via web-based questionnaires. Absolute effect sizes (AES) were generated to demonstrate the impact of disease on domain scores. Four children were excluded because of missing glomerular filtration rate (GFR) estimations.

RESULTS

Of the 229 children included in the final analysis, 221 completed the entire PROMIS questionnaire. Unadjusted PROMIS domains were responsive to chronic kidney disease activity indicators and number of coexisting conditions. PROMIS domain scores were worse in the presence of recent hospitalizations (depression AES 0.33, anxiety AES 0.42, pain interference AES 0.46, fatigue AES 0.50, mobility AES 0.49), edema (depression AES 0.50, anxiety AES 0.60, pain interference AES 0.77, mobility AES 0.54) and coexisting medical conditions (social peer-relationships AES 0.66, fatigue AES 0.83, mobility AES 0.60, upper extremity function AES 0.48).

CONCLUSIONS

The PROMIS pediatric domains of depression, anxiety, social-peer relationships, pain interference, and mobility were sensitive to the clinical status of children with chronic kidney disease in this multi-center cross sectional study. We demonstrated that a number of important clinical characteristics including recent history of hospitalization and edema, affected patient perceptions of depression, anxiety, pain interference, fatigue and mobility. The PROMIS instruments provide a potentially valuable tool to study the impact of chronic kidney disease. Additional studies will be required to assess responsiveness in PROMIS score with changes in disease status over time.

Strategies for Measuring Quality of Life among Pediatric Solid-Organ Transplant Recipients

Objective

Quality of life (QoL) has become a mainstay in the outcome assessment of pediatric solid-organ transplant recipients. Yet, how QoL is operationalized and measured varies drastically. It may be very difficult for clinicians and researchers to determine which methods of QoL assessment best meet the needs of their patients or study. The purpose of this literature review is to describe and evaluate the current status of QoL measurement in studies of pediatric solid-organ transplant recipients.

Data Sources

Searches of PubMed and PsycINFO from January 1985 to February 2012.

Study Selection

English peer-reviewed publications that described a method for measuring QoL whether it was a standardized questionnaire, qualitative approach, or another way of operationalizing the construct.

Data Extraction

QoL measurement strategies were extracted from 43 studies that met inclusion criteria.

Data Synthesis

Each article was reviewed and summarized by 2 study team members.

Conclusions

Many different strategies were used for measurement, and some were not consistent with established conceptualizations of QoL. Overall recommendations for best practices are offered. Detailed information about specific measures is included, and measures that seem to capture the construct well are recommended. Additionally, our review highlighted the importance of using a “battery approach,” including child and parent report as well as considering other variables, such as patient's age, when selecting a QoL measurement strategy.

Children and adolescents on hemodialysis: attributes associated with quality of life


The aim of this study was to estimate the prevalence and factors associated with the occurrence of incidents related to medication, registered in the medical records of patients admitted to a Surgical Clinic, in 2010. This is a cross-sectional study, conducted at a university hospital, with a sample of 735 hospitalizations. Was performed the categorization of types of incidents, multivariate analysis of regression logistic and calculated the prevalence. The prevalence of drug-related incidents was estimated at 48.0% and were identified, as factors related to the occurrence of these incidents: length of hospitalization more than four days, prescribed three or more medications per day and realization of surgery intervention. It is expected to have contributed for the professionals and area managers can identify risky situations and rethink their actions.


Health-related quality of life of children and adolescents with CKD stages 4-5 and their caregivers

BACKGROUND

Renal replacement therapies may affect the quality of life of patients and their primary caregivers (PC).

METHODS

This study describes the perception of health-related quality of life (HRQoL) of children/adolescents with CKD stages 4-5, as well as of their PC (n = 64), in comparison to healthy peers and their PC (n = 129), respectively, based on the Peds QL™ 4.0 and Short Form-36 (SF-36) questionnaires and selected biomarkers.

RESULTS

Patients reported a deleterious impact on physical capacity and on social and school activities. A negative influence on emotional aspects was reported by older patients, but not by their PC. Hemodialysis, followed by peritoneal dialysis, had a more negative impact on patients' physical functioning domain. PC HRQol proxy reports differed from those of their children, especially in older patients. PC of both groups presented similar SF-36 scores. An association was demonstrated between the magnitude of treatment target inadequacies, lower specific dominion scores in the patients/PC proxy reports and PC SF-36 general health scores.

CONCLUSION

The HRQoL of patients with CKD stages 4-5 is negatively affected to different degrees depending on age and treatment modality. The results suggest an association between worsening HRQoL parameters and inadequate control of recognized therapeutic CKD treatment targets.

Factors affecting growth and final adult height after pediatric renal transplantation

BACKGROUND

Growth retardation is a common problem for children with chronic kidney disease. Although renal transplantation (RTx) resolves endocrine metabolic and uremic disturbances, growth continues to be suboptimal. This study aims to describe changes in height from diagnosis to final adult height (FAH) in Korean renal allograft recipients and determine factors associated with posttransplantation growth.

METHODS

We retrospectively reviewed 63 renal allograft recipients who underwent RTx at <15 years of age with regular follow-up for >3 years afterwards. Pre- and post-RTx growth was analyzed by height Z scores (Ht_Z) at RTx, 2 and 5 years follow-up, and at FAH.

RESULTS

Ht_Z decreased from diagnosis to dialysis by -0.8 (P = .009) and from dialysis to RTx by -0.46 (P < .001). The mean baseline Ht_Z at RTx was -1.62 ± 1.36. The change in Ht_Z at 2 and 5 years after transplantation was 0.68 ± 0.88 and 0.48 ± 0.86, respectively. Both variables were negatively correlated with baseline age at RTx. Mean FAH was -1.22 ± 1.11 and was positively correlated with baseline height at RTx. Height at start of dialysis and dialysis duration were significant determinants of baseline height at RTx (P < .001).

CONCLUSIONS

Although there is significant posttransplant catch-up growth among younger recipients and among those with greater baseline height deficit, catch-up growth is not sustained and greater FAH is attained in those who are taller at RTx. Achieving greater height before dialysis and decreasing dialysis duration leads to maximal height at RTx as well as greater FAH.

'It is life threatening but I don't mind'. A qualitative study using photo elicitation interviews to explore adolescents' experiences of renal replacement therapies

BACKGROUND

Renal replacement therapy (RRT) transforms the life prospects of young people with established renal failure. However, these treatments can have significant physiological and psychological implications for adolescents as they prepare to transition into adulthood. Health policies increasingly emphasize children and youth's active participation and consultation as users of health services, yet studies infrequently seek their experiences directly.

METHODS

  Adolescents receiving RRT in a large UK teaching hospital took photographs illustrating the impact of their condition and treatment on their lives. Qualitative photo elicitation interviews were conducted to explore the significance of the images and the young person's experiences. Interviews were analysed using descriptive thematic analysis.

RESULTS

Ten young people aged 13-17 years participated. Themes identified were: (1) understanding and acceptance of treatment; (2) living in a non-functioning body; (3) impact upon daily life; (4) sources of support. Young people found treatments challenging and experienced significant impact on relationships and daily routines. Yet, health was prioritized over body image and participants demonstrated great emotional resilience. Young people valued support from family and friends, although were wary of disclosing their condition in case it resulted in being highlighted as different. Young people reported hospital staff as being caring and professional, but their biggest virtue appeared to be their willingness to treat the young people as 'normal'.

CONCLUSIONS

  Young people engaged readily with the research, and frankly described the impact of RRT on their everyday lives. Service providers must ensure that adolescents' developmental needs are met as traditional tasks of adolescence may lose priority. However, it is also clear that young people's ability to cope with treatments should not be underestimated.

Assessment of identity and quality of life in diabetic and renal transplant adolescents in comparison to healthy adolescents

Identity development represents a central task of adolescence. Identity achievement is characterized by a coherent sense of who one is following a period of exploration and can help navigate the challenges of adulthood. This study examined identity within a quality of life (QOL) context in 85 adolescents with a renal transplant or with Type 1 diabetes in comparison to 90 healthy controls. Results revealed significant differences in ideological identity, with patients showing higher levels of diffusion and controls showing higher levels of foreclosure. No differences with respect to interpersonal identity, QOL, perceived control over the QOL domains, and perceived opportunities for growth and development were found. Future research should assess identity and QOL over a longer period of time to determine whether differences between chronically ill and healthy young adults can be detected.

Outcomes and predictive factors of pediatric kidney transplants: an analysis of the Thai Transplant Registry

As universal coverage for pediatric kidney transplantation (KT) was introduced in Thailand in 2008, the number of recipients has been increasing. We evaluated predictive factors for graft failure to understand how to improve clinical outcomes in these children. Using data obtained from the National Transplant registry, we assessed the risk of graft failure using the Kaplan-Meier method and Cox proportional hazards regression. Altogether, 201 recipients aged <21 yr at the time of KT were studied. Living donors (LD) were significantly older than deceased donor (DD). Mean cold ischemia time of DD was 17 h. The mean donor glomerular filtration rate (GFR) was 84.0 mL/min/1.73 m(2) . Induction immunosuppressive therapy was administered more frequently in DD than in LDKT. Delayed graft function (DGF) occurred in 36 transplants. Over 719 person years of follow-up, 42 graft failures occurred. Graft survival at one, three, and five yr post-transplant were 95%, 88% and 76%, respectively. Two factors independently predicted graft failure in multivariate analysis. The hazard ratios for graft failure in patients with DGF and in patients with donor GFR of ≤30 mL/min/1.73 m(2) were 2.5 and 9.7, respectively. Pediatric recipients should receive the first priority for allografts from young DD with a good GFR, and DGF should be meticulously prevented.

Health-related quality of life functioning over a 2-year period in children with end-stage renal disease

BACKGROUND

Optimal care of the pediatric chronic kidney disease/end stage renal disease (CKD/ESRD) patient must now incorporate health-related quality of life (HRQOL) assessment and management.

METHODS

This study reports the first data on longitudinal change in global (PedsQL(TM)4.0) and disease-specific (PedsQL(TM)3.0 ESRD Module) HRQOL pediatric ESRD patient and proxy ratings over four assessment periods spanning approximately a 2-year period. General linear mixed modeling was used to analyze associations between patient demographics, medical variables, and patient and proxy HRQOL scores.

RESULTS

Self-reported and/or proxy data were available for at least two time-points for 53 patients (age 2-18 years; 60 % male), of whom 27 were receiving in-center hemodialysis.

CONCLUSIONS

Patient ratings on global health and physical activity, emotional, and social and disease-specific worry and communication domains were higher (i.e., better) than parent-proxy ratings, confirming the importance of obtaining both sources of information. Patients on dialysis longer, particularly females, reported worse emotional functioning; females also reported more physical appearance concerns. Parents rated older children and those on dialysis longer as functioning worse on multiple global and disease-specific (e.g., fatigue, relationship) domains. Parents also rated children as functioning increasingly worse in school over time. Further, patient ESRD history (acute onset vs. medically managed) impacted how parents viewed the burden of ESRD on their child over time.

Health-related quality of life and functional outcomes from a randomized, controlled study of lisdexamfetamine dimesylate in children and adolescents with attention deficit hyperactivity disorder

BACKGROUND

Optimal management of attention deficit hyperactivity disorder (ADHD) aims not only to ameliorate patients' symptoms, but also to improve health-related quality of life (HRQL) and functioning. A pivotal, 7-week, randomized, double-blind, placebo-controlled, phase III study in children and adolescents in ten European countries demonstrated that the stimulant prodrug lisdexamfetamine dimesylate (LDX) is an effective and generally well-tolerated treatment for symptoms of ADHD.

OBJECTIVE

The aim of this study was to assess HRQL and functional impairment outcomes in this clinical trial, using the Child Health and Illness Profile-Child Edition: Parent Report Form (CHIP-CE:PRF) and the Weiss Functional Impairment Rating Scale-Parent Report (WFIRS-P), respectively.

METHODS

Patients (aged 6-17 years) with diagnosed ADHD and a baseline ADHD Rating Scale IV total score ≥28 were randomized (1:1:1) to 7 weeks of double-blind treatment with once-daily LDX, placebo or the reference treatment, osmotic-release oral system methylphenidate (OROS-MPH). Participants' parents (or legally authorized representatives) completed the CHIP-CE:PRF and WFIRS-P questionnaires at baseline, at weeks 4 and 7, and/or at early termination. Endpoint was defined as the last on-treatment visit with valid data (≤30 % missing items). The CHIP-CE:PRF Achievement domain was pre-specified as the primary HRQL outcome.

RESULTS

The full analysis set comprised 317 patients (LDX, n = 104; placebo, n = 106; OROS-MPH, n = 107), the majority of whom completed the study (LDX, n = 77; placebo, n = 42; OROS-MPH, n = 72). Baseline CHIP-CE:PRF T-scores in four of the five domains were ≥1 standard deviation below norms (US community samples). Compared with placebo, LDX was associated with statistically significantly improved T-scores from baseline to endpoint in these four domains, with effect sizes of 1.280 (p < 0.001) in Achievement, 1.079 (p < 0.001) in Risk Avoidance, 0.421 (p < 0.01) in Resilience and 0.365 (p < 0.05) in Satisfaction. In LDX-treated patients, placebo-adjusted improvements from baseline to endpoint in WFIRS-P scores were statistically significant (p < 0.001) for total score and four of the six domains, with effect sizes of 0.924 (total score), 1.249 (Learning and School), 0.730 (Family), 0.643 (Social Activities) and 0.640 (Risky Activities). OROS-MPH treatment showed similar patterns of improvement from baseline to endpoint in both CHIP-CE:PRF and WFIRS-P scores.

CONCLUSIONS

Baseline HRQL and functional impairment scores reflect the burden of untreated ADHD. The benefits of short-term stimulant treatment in children and adolescents with ADHD extend beyond symptomatic relief and impact positively on HRQL and daily functioning.

[Paediatric features in childhood renal transplantation: quality of life, school, adherence, transfer to adult nephrologists]

The quality of life of children having undergone renal transplantation is slightly lower than in the general population, whereas it is rather better in transplanted adolescents. The parent's quality of life is often affected. School attendance is affected by the disease and school performances lower as an outcome, however the level of unemployment at adulthood remains similar to the general population. Treatment compliance is high in young children, but low in adolescents, resulting in frequent rejection episodes and reduced graft survival. Multidisciplinary patient management is essential, possibly in a patient's therapeutic education unit. Implementation of special measures is recommended to reduce the risks associated with the transition from pediatric to adult unit.

Clinical features and outcomes of 98 children and adults with dense deposit disease

BACKGROUND

Dense deposit disease (DDD) is an ultra-rare renal disease.

METHODS

In the study reported here, 98 patients and their families participated in a descriptive patient-centered survey using an online research format. Reports were completed by patients (38%) or their parents (62%). Age at diagnosis ranged from 1.9 to 38.9 years (mean 14 years).

RESULTS

The majority of patients presented with proteinuria and hematuria; 50% had hypertension and edema. Steroids were commonly prescribed, although their use was not evidence-based. One-half of the patients with DDD for 10 years progressed to end-stage renal disease (ESRD), with young females having the greatest risk for renal failure. Of first allografts, 45% failed within 5 years, most frequently due to recurrent disease (70%). Type 1 diabetes (T1D) was present in over 16% of families, which represents a 116-fold increase in incidence compared with the general population (p < 0.001).

CONCLUSIONS

Based on these findings, we suggest that initiatives are needed to explore the high incidence of T1D in family members of DDD patients and the greater risk for progression to ESRD in young females with DDD. These efforts must be supported by sufficient numbers of patients to establish evidence-based practice guidelines for disease management. An international collaborative research survey should be implemented to encourage broad access and participation.

Health-related quality of life measurement in children and adolescents in Ibero-American countries, 2000 to 2010

OBJECTIVES

To analyze the characteristics of instruments designed to assess the health-related quality of life (HRQOL) in children, developed or adapted from 2000 to 2010 in Argentina, Chile, Mexico, Spain, and Uruguay.

METHODS

The protocol-led literature review included database searching (e.g., Medline, ISI Science Citation Index) and manual searching to retrieve studies focused on measures of HRQOL, health status, or well-being addressed to children and adolescents. Country-specific filters were applied to identify studies carried out in the participating countries. The characteristics of the instruments and type of studies were analyzed. Descriptive characteristics and psychometric properties were analyzed following the guidelines of the Scientific Advisory Committee of the Medical Outcomes Trust.

RESULTS

Ninety-nine documents were included. Thirty-one questionnaires were identified, 24 instruments were adapted, and the psychometric properties of 20 HRQOL instruments were reported in the study period. There was substantial variability in the number and characteristics of the dimensions included. Reliability was generally acceptable, and the majority of instruments provided data on internal consistency (n = 18) and, to a lesser extent, on test-retest reliability (n = 12). Nearly all studies reported construct validity, but only four analyzed sensitivity to change.

CONCLUSIONS

There is a scarcity of instruments to measure HRQOL of children and adolescents in the countries analyzed. Certain psychometric characteristics have been reasonably well tested, but others, most notably sensitivity to change, have not been tested in most instruments. Extension of this study to other Latin American countries would help to further identify gaps in this area and promote the use of HRQOL measurement in children and adolescents in Spanish-speaking cultures.

Does allograft failure impact school attendance in children? A NAPRTCS study

BACKGROUND

Studies show that adult dialysis patients with allograft failure have increased mortality and morbidity on dialysis compared to transplant naïve patients. We previously showed comparable mortality risk in pediatric dialysis patients after allograft failure compared to transplant naïve patients; the impact on morbidity is less clear. Specifically, the effect of allograft failure on school attendance in pediatric patients has not previously been studied.

METHODS

Using the North American Pediatric Renal Trials and Collaborative Studies database, we compared school attendance between transplant naïve and allograft failure patients from 1 January 1992 to 31 December 2007. School attendance was compared between the two groups at 6 and 12 months after dialysis initiation using a chi-square test. Factors which can potentially impact on school attendance data were evaluated using a multivariate logistic regression analysis.

RESULTS

There were 2783 patients who had a follow-up at least 6 months after dialysis initiation and were capable of attending school during the study period. Patients were categorized by transplant history: previous allograft failure (n=576) and transplant naïve (n=2207). At 6 months, full-time school attendance was 67.2% in the allograft failure group and 72.3% in the transplant naïve group (P=0.0164). At 12 months, attendance was 68.6% in the allograft failure group and 72.5% in the transplant naïve group (P=0.103). After covariate adjustment, transplant failure did not impact school attendance at either 6 or 12 months follow-up [hazard ratio (HR) 1.12, confidence interval (CI) 0.91-1.39; HR 0.99, CI 0.78-1.27, respectively].

CONCLUSIONS

Children with failed allografts who return to dialysis have comparable school attendance compared to their transplant naïve dialysis counterparts. These results suggest that transplant failure is not an adverse prognostic factor for quality of life as measured by full-time school attendance.

Self-reported quality of life in children and young people with chronic kidney disease

Chronic kidney disease (CKD) would be expected to impact upon the quality of life (QoL) of children and young people; therefore, it is important that they are given the means to express their opinions about how they perceive their own QoL. We used the Generic Children's Quality of Life Measure (GCQ) in 225 paediatric renal patients (118 male, mean age 13.6 years, range 6.2-18.9 years) from seven UK centres. Of these, 47 were on dialysis (23 on haemodialysis), 128 were post-transplant (47 pre-emptive) and 49 had advanced CKD. A comparison between the 124 renal patients (65 male, mean age 11.2 years) in the same age range as the general population (6-14 years) showed a higher GCQ QoL score for the renal patients (p = 0.02). Analysis of the whole group of renal patients (n = 225) revealed no significant difference between the mean GCQ scores of participants in various treatment modalities (p = 0.26) and no significant differences between gender (p = 0.90) and age group (p = 0.44). The results indicate that young people can perceive their QoL as good despite living with what others may perceive as severe limitations. This may seem counter-intuitive, but QoL is a subjective measure and thus may be difficult to predict from observable limitations (health status). The GCQ is an ideal measure for use in annual departmental audits of generic paediatric QoL and may help to individualise the work of psychosocial teams with each patient.

Preemptive transplantation and the transplant first initiative

PURPOSE OF REVIEW

Preemptive kidney transplant (PKT) is the focus of a new initiative, 'Transplant First'. This initiative focuses on increasing patient transition to transplantation prior to the need for dialysis. This review will evaluate the benefits of PKT and means to accomplish this goal.

RECENT FINDINGS

Outcomes data show PKT significantly improves long-term survival for the recipient and the allograft. In addition quality of life is improved. This also holds true for children and particularly for adolescents. In 2008, 5.7% of incident patients with end-stage renal disease were placed on the waiting list before beginning dialysis and 0.8% underwent preemptive living donor transplant before wait listing. If patients are evaluated before starting dialysis and are acceptable candidates, up to 40% will receive a preemptive transplant. Recent articles stress that patients want information from their physician; important impediments to PKT remain provider and patient education, insurance coverage and patient reluctance to ask for living donation.

SUMMARY

Preemptive transplant saves lives. Increased education focused on providers, patients and entire communities is key, as is an increase in living donation. Furthermore, to maximize the impact of transplant first, increased living donor protections and immunosuppression coverage for the life of the allograft are essential.

Quality of life in children with chronic kidney disease (with child and parent assessments)

Herein the results of a multicenter study from the Turkish Pediatric Kidney Transplantation Study Group are reported. The aims of this study were to compare the quality of life (QoL) scores of Turkish children who are dialysis patients (DP), renal transplant recipients (TR), and age-matched healthy controls and to compare child-self and parent-proxy scores. The Turkish versions of the Kinder Lebensqualität Fragebogen (KINDL(R)) questionnaires were used as a QoL measure. The study group consisted of 211 children and adolescents with chronic kidney disease (CKD) (139 TR and 72 DP aged between 4-18 years; 13.7 +/- 3.5 years) from 11 university hospitals, 129 parents of these patients, 232 age-matched healthy children and adolescents (aged between 4-18 years; 13.1+/-3.5 years) and 156 of their parents. Patients with CKD had lower scores in all subscales except for physical well-being than those in the control group. TR had higher scores in physical well-being, self-esteem, friends' subscales, and total scores than DP. Child-self scores were lower than parent-proxy scores, especially in CKD, DP, and control groups. Concordance between parent-proxy and child-self reports in the TR, DP, CKD, and control groups was only moderate for the majority of subscales (r = 0.41-0.61). It was concluded that parent-proxy scores on the QoL were not equivalent to child-self scores and that evaluating both children's and parents' perspectives were important. Additionally, psychosocial counseling is crucial not only for patients with CKD but also for their parents.

Kidney organ donation: developing family practice initiatives to reverse inertia

BACKGROUND

Kidney transplantation is associated with greater long term survival rates and improved quality of life compared with dialysis. Continuous growth in the number of patients with kidney failure has not been matched by an increase in the availability of kidneys for transplantation. This leads to long waiting lists, higher treatment costs and negative health outcomes.

DISCUSSION

Misunderstandings, public uncertainty and issues of trust in the medical system, that limit willingness to be registered as a potential donor, could be addressed by community dissemination of information and new family practice initiatives that respond to individuals' personal beliefs and concerns regarding organ donation and transplantation.

SUMMARY

Tackling both personal and public inertia on organ donation is important for any community oriented kidney donation campaign.

Approach to optimizing growth, rehabilitation, and neurodevelopmental outcomes in children after solid-organ transplantation

One of the most critical differences between the posttransplant care of children and adults is the requirement in children to maintain a state of health that supports normal physical and psychological growth and development. Most children with organ failure have some degree of growth failure and developmental delay, which is not quickly reversed after successful transplantation. The challenge for clinicians caring for these children is to use strategies that minimize these deficits before transplantation and provide maximal opportunity for recovery of normal developmental processes during posttransplant rehabilitation. The effect of chronic organ failure, frequently complicated by malnutrition, on growth potential and cognitive development is poorly understood. This review presents a summary of what is known regarding risk factors for suboptimal growth and development following solid-organ transplant and describe possible strategies to improve these outcomes.

Transition of care to adult services for pediatric solid-organ transplant recipients

The importance of transition to adult health care for young people with chronic conditions is increasingly recognized. Ensuring effective engagement with adult services for adolescents and young-adult solid-organ transplant recipients is as critical for immediate graft survival as it is for their future health and well-being. This article (1) examines the definitions of adolescence and emerging adulthood and some of the challenges of these phases of life, (2) discusses elements that may influence motivation and engagement and enhance communication and adherence for adolescents and young adults, (3) highlights important areas in education, vocational planning, and quality of life for transplant recipients, (4) reviews tasks and challenges during the transition, and (5) provides specific transition recommendations, for both transplant health care professionals and for primary care providers practicing outside transplant centers.
