Chronic kidney disease (CKD) has become a significant public health concern, as it is associated with substantial morbidity. Prior research has evaluated multiple novel CKD biomarkers to supplement serum creatinine and proteinuria. The ultimate goal of this research is to find biomarkers that can be used to accurately predict CKD progression and to better time outpatient follow-up, and referral for transplant. Also, an optimal panel of biomarkers can augment the predictive value of proteinuria and serum creatinine by enriching patient enrollment in clinical trials...

The definition of congenital anomalies of the kidney and urinary tract (CAKUT) is the disease of structural malformations in the kidney and/or urinary tract containing vesicoureteral reflux (VUR). These anomalies can cause pediatric chronic kidney disease. However, the pathogenesis of CAKUT is not well understood, because identifying the genetic architecture of CAKUT is difficult due to the phenotypic heterogeneity and multifactorial genetic penetrance. We describe the current genetic basis and mechanisms of CAKUT including VUR via approaching the steps and signaling pathways of kidney developmental processes...

OBJECTIVES: Malnutrition and wasting predict clinical outcomes in children with severe chronic illness. Objectively calculated malnutrition in children with end-stage organ failure has not been well studied. This analysis compares children with kidney, liver or intestine failure to healthy controls to quantitate the disparity in muscle and fat stores. METHODS: Children younger than age 19 with end stage liver, kidney or intestine failure and with pre-transplant computed tomography (CT) imaging were selected from the transplant database...

Monitoring metabolic adaptation to chronic kidney disease (CKD) early in the time course of the disease is challenging. As a non-invasive technique, analysis of exhaled breath profiles is especially attractive in children. Up to now, no reports on breath profiles in this patient cohort are available. 116 pediatric subjects suffering from mild-to-moderate CKD (n = 48) or having a functional renal transplant KTx (n = 8) and healthy controls (n = 60) matched for age and sex were investigated. Non-invasive quantitative analysis of exhaled breath profiles by means of a highly sensitive online mass spectrometric technique (PTR-ToF) was used...

BACKGROUND: Growth impairment remains common in children with chronic kidney disease (CKD). Available literature indicates low level of recombinant human growth hormone (rhGH) utilization in short children with CKD. Despite efforts at consensus guidelines, lack of high-level evidence continues to complicate rhGH therapy decision-making and the level of practice variability in rhGH treatment by pediatric nephrologists is unknown. METHODS: Cross-sectional online survey electronically distributed to pediatric nephrologists through the Midwest Pediatric Nephrology Consortium and American Society of Pediatric Nephrology...

REVIEW
Stephen R Hooper
This mini review provides an overview of the issues and challenges inherent in autosomal recessive polycystic kidney disease (ARPKD), with a particular focus on the neurological factors and neurocognitive functioning of this population. ARPKD typically is discovered at the end of pregnancy or during the neonatal developmental period and occurs in approximately 1 in 20,000 live births. During the neonatal period, there is a relatively high risk of death, with many infants dying from respiratory failure. As the child ages, they experience progressive kidney disease and become increasingly vulnerable to liver disease, with many individuals eventually requiring dual organ transplants...

PURPOSE: Although primarily a mental health disorder, anorexia nervosa (AN) has many physical consequences. Among them, the consequences on kidney function are often underestimated. We evaluated renal function in adolescent AN inpatients and investigated the correlation between the GFR and intrinsic patient characteristics. METHODS: A single-center retrospective study was conducted on 51 patients hospitalized for the restrictive type of AN in 2013. Data were divided into: (1) medical history of AN; (2) growth parameters and vital signs upon admission; and (3) blood tests...

BACKGROUND: 2 valid and reliable estimated glomerular filtration rate (GFR) equations for the pediatric population have been developed from directly measured GFR data in the Chronic Kidney Disease in Children (CKiD) cohort: the full CKiD and bedside CKiD equations. Although adult GFR estimating equations replicate relationships of measured GFR with biomarkers, it is unclear whether similar patterns exist among children and adolescents with chronic kidney disease (CKD). STUDY DESIGN: Prospective cohort study in children and adolescents...

Hyperhomocysteinemia has attracted a lot of attention in renal patients, not only because of its close relationship with renal function but also because it has been implicated as an independent cardiovascular risk factor in these patients. An increased level of C-reactive protein (CRP) has been reported to be a strong predictor of cardiovascular mortality in hemodialysis (HD) patients. The aim of this study was to assess the association between homocysteine (Hcy) and highly sensitive CRP (hsCRP) in cardiovascular risk prediction in children with chronic kidney disease (CKD) on HD...

Loss of lean body mass is a relevant component of the cachexia, or protein energy wasting (PEW), syndrome. Reduced muscle mass seems to be the most solid criterion for the presence of cachexia/PEW in patients with chronic kidney disease (CKD), and those with greater muscle mass loss have a higher risk of death. Children with CKD have many risk factors for lean mass and muscle wasting, including poor appetite, inflammation, growth hormone resistance, and metabolic acidosis. Mortality risks in patients with CKD increases as body mass index (BMI) and weight decreases...

This study examined roles and experiences of fathers of children with chronic kidney disease (CKD). Based on interpretive description, semistructured interviews were conducted with 22 fathers of children receiving a range of treatments (transplant, peritoneal dialysis, hemodialysis, and CKD not requiring renal replacement therapy). Fathers described various experiences and means of adjusting to shifts associated with pediatric CKD. These included loss of personal control, a sense of personal isolation, and a stance of remaining strong amidst personal suffering...

AIMS: Many of the secondary effects of high levels of molybdenum (Mo) overlap with symptoms commonly seen in pediatric patients with chronic kidney disease (CKD). We measured plasma Mo levels and examined the relationship between Mo levels and kidney function. MATERIALS AND METHODS: The study was carried out at the London Health Sciences Centre in London, Ontario, Canada with 36 children and adolescents 4 - 18 years of age with CKD. There were 1 - 6 trace element measurements (Mo and copper (Cu)) per patient...

OBJECTIVES: Renal manifestations are the second most significant cause of morbidity and mortality in patients with tuberous sclerosis complex (TSC), and include renal cysts, angiomyolipomas, fat-poor lesions, and malignant tumors. These lesions begin in childhood and often lead to chronic kidney disease (CKD). Little is known on the incidence of early modifiable risk factors of CKD, such as proteinuria and hypertension, or subtle decreases in glomerular filtration rate that correspond to the early stages of CKD in children with TSC...

BACKGROUND: There is inadequate power to perform a valid clinical trial in pediatric heart transplantation (HT) using a conventional end-point, because the disease is rare and hard end-points, such as death or graft loss, are infrequent. We sought to develop and validate a surrogate end-point involving the cumulative burden of post-transplant complications to predict death/graft loss to power a randomized clinical trial of maintenance immunosuppression in pediatric HT. METHODS: Pediatric Heart Transplant Study (PHTS) data were used to identify all children who underwent an isolated orthotopic HT between 2005 and 2014 who survived to 6 months post-HT...

PURPOSE OF REVIEW: In this paper, we review the pathogenesis and treatment of chronic kidney disease-mineral and bone disorder (CKD-MBD), especially as it relates to pediatric CKD patients. RECENT FINDINGS: Disordered regulation of bone and mineral metabolism in CKD may result in fractures, skeletal deformities, and poor growth, which is especially relevant for pediatric CKD patients. Moreover, CKD-MBD may result in extra-skeletal calcification and cardiovascular morbidity...

The complex pathophysiology of progressive chronic kidney disease (CKD) and the development of mineral and bone disorder, abbreviated as CKD-MBD, is of vital importance to a pediatric patient. Paricalcitol, the 19 nor-1,25(OH)2D2 analogue was shown to be effective and safe in the treatment of secondary hyperparathyroidism (SHPT) in adults almost two decades ago. It also significantly improved survival in dialysis patients compared to the standard calcitriol. The successful treatment of CKD-MBD in children is essential if they are to grow and survive into adulthood...
