BACKGROUND AND OBJECTIVES: Prior studies suggested that women with CKD have higher risk for cardiovascular disease (CVD) and mortality than men, although putative mechanisms for this higher risk have not been identified. We assessed sex differences in (1) CVD risk factors and left ventricular hypertrophy (LVH), and (2) the relationship of left ventricular mass (LVM) with different measures of body size in children with CKD. DESIGN, SETTING, PARTICIPANTS, AND MEASUREMENTS: The study population comprised 681 children with CKD from the Chronic Kidney Disease in Children cohort, contributing 1330 visits...

BACKGROUND: Chronic kidney disease (CKD) is a global health burden, yet it is still underrepresented within public health agendas in many countries. Studies focusing on the natural history of CKD are challenging to design and conduct, because of the long time-course of disease progression, a wide variation in etiologies, and a large amount of clinical variability among individuals with CKD. With the difference in health-related behaviors, healthcare delivery, genetics, and environmental exposures, this variability is greater across countries than within one locale and may not be captured effectively in a single study...

BACKGROUND AND OBJECTIVES: Plasma fibroblast growth factor 23 (FGF23) concentrations increase early in the course of CKD in children. High FGF23 levels associate with progression of CKD in adults. Whether FGF23 predicts CKD progression in children is unknown. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: We tested the hypothesis that high plasma FGF23 is an independent risk factor for CKD progression in 419 children, aged 1-16 years, enrolled in the Chronic Kidney Disease in Children (CKiD) cohort study...

BACKGROUND: Previous studies have suggested that some children with autosomal recessive polycystic kidney disease (ARPKD) have growth impairment out of proportion to their degree of chronic kidney disease (CKD). The objective of this study was to systematically compare growth parameters in children with ARPKD to those with other congenital causes of CKD in the chronic kidney disease in Children (CKiD) prospective cohort study. METHODS: Height SD scores (z-scores), proportion of children with severe short stature (z-score < -1...

PURPOSE: Kidney stone disease has become increasingly common during childhood and adolescence; however, the rate of symptomatic kidney stone recurrence for pediatric patients is uncertain. MATERIALS AND METHODS: We performed a retrospective cohort study of patients aged 3-18 years without anatomic abnormalities or genetic causes of nephrolithiasis who presented with a first symptomatic kidney stone between 2008 and 2014. We determined recurrence rates of symptomatic nephrolithiasis, defined as a new kidney stone on ultrasound and/or CT associated with pain and/or vomiting...

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...

Pneumococcal vaccination rates among children receiving a kidney transplant remain suboptimal. Current practice guidelines in the United States recommend giving the PPSV23 after priming with the PCV13. We conducted a QI initiative to increase pneumococcal vaccine rates in our kidney transplant recipients by developing an age-based vaccine algorithm, obtaining vaccine records, and generating reminders for patients and clinicians. A monthly report from the EHR tracked outcomes. The process metric was missed vaccine opportunities, and the overall objective was to improve coverage with both the PCV13 and PPSV23...

BACKGROUND: Children with chronic kidney disease (CKD) and hypertension have increased blood pressure variability (BPV), which has been associated with lower neurocognitive test scores in adults. Children with CKD are at risk for decreased neurocognitive function. Our objective was to determine whether children with CKD and increased BPV had worse performance on neurocognitive testing compared with children with CKD and lower BPV. METHODS: This was a cross-sectional and longitudinal analysis of the relation between BPV and neurocognitive test performance in children ≥6 years enrolled in the Chronic Kidney Disease in Children (CKiD) study...

BACKGROUND: Individuals of African ancestry harboring two variant alleles within apolipoprotein L1 (APOL1) are classified with a high-risk (HR) genotype. Adults with an HR genotype have increased risk of focal segmental glomerulosclerosis and chronic kidney disease compared with those with a low-risk (LR) genotype (0 or 1 variants). The role of APOL1 risk genotypes in children with glomerular disease is less well known. METHODS: This study characterized 104 African-American children with a glomerular disease by APOL1 genotype in two cohorts: the Chronic Kidney Disease in Children (CKiD) and Nephrotic Syndrome Study Network (NEPTUNE)...

OBJECTIVE: The Fontan operation is a palliative procedure for congenital single ventricle heart disease. Long-term kidney function in this cohort is not well-known. Our aim was to evaluate renal function in long-term survivors post-Fontan palliation, and we hypothesize that this cohort will have a higher prevalence of chronic kidney disease (CKD) compared to controls. DESIGN: We performed a retrospective cohort study of 68 subjects evaluated through the Single Ventricle Survivorship Program at the Children's Hospital of Philadelphia between July 2010 and December 2014 compared to 70 healthy children similar in age and sex...

PURPOSE: Low renal parenchymal area, which is the gross area of the kidney in maximal longitudinal length minus the area of the collecting system, has been associated with increased risk of end stage renal disease during childhood in boys with posterior urethral valves. To our knowledge normal values do not exist. We aimed to increase the clinical usefulness of this measure by defining normal renal parenchymal area during infancy. MATERIALS AND METHODS: In a cross-sectional study of children with prenatally detected mild unilateral hydronephrosis who were evaluated between 2000 and 2012 we measured the renal parenchymal area of normal kidney(s) opposite the kidney with mild hydronephrosis...

BACKGROUND: After hematopoietic cell transplantation (HCT), polyoma-BK virus is associated with hemorrhagic cystitis and also with polyomavirus nephropathy (PVN). However, the true burden of post-HCT PVN is unknown because kidney biopsies are avoided due to their bleeding risk. The novel, noninvasive urinary PV-Haufen test detects PVN in kidney transplant recipients with greater than 95% positive/negative predictive values. We hypothesized that the detection of PV-Haufen in voided urine samples-a positive PV-Haufen test-was also clinically significant after HCT...

BACKGROUND: Children with chronic kidney disease (CKD) may have impaired caloric intake through a variety of mechanisms, with decreased appetite as a putative contributor. In adult CKD, decreased appetite has been associated with poor clinical outcomes. There is limited information about this relationship in pediatric CKD. METHODS: A total of 879 participants of the Chronic Kidney Disease in Children (CKiD) study were studied. Self-reported appetite was assessed annually and categorized as very good, good, fair, or poor/very poor...

BACKGROUND: Self-reported physical activity (PA) and screen time exposure in adolescents with chronic kidney disease (CKD) has not been evaluated. METHODS: We performed a cross-sectional analysis of PA and screen time in 224 adolescents at entry into the Chronic Kidney Disease in Children (CKiD) cohort. We compared proportions of CKiD vs. healthy 2012 National Health and Nutrition Examination Survey (NHANES) participants reporting the recommended 60 min of PA 7 days/week or ≤ 2 h/day of entertainment screen time (binomial probability test)...

Atlas-based automated anatomical labeling is a fundamental tool in medical image segmentation, as it defines regions of interest for subsequent analysis of structural and functional image data. The extensive investigation of multi-atlas warping and fusion techniques over the past 5 or more years has clearly demonstrated the advantages of consensus-based segmentation. However, the common approach is to use multiple atlases with a single registration method and parameter set, which is not necessarily optimal for every individual scan, anatomical region, and problem/data-type...
