BACKGROUND: Clinical care decisions to treat chronic kidney disease (CKD) in a growing child must often be made without the benefit of evidence from clinical trials. We used observational data from the Chronic Kidney Disease in Children cohort to estimate the effectiveness of renin-angiotensin II-aldosterone system blockade (RAAS) to delay renal replacement therapy (RRT) in children with CKD. METHODS: A total of 851 participants (median age: 11 years, median glomerular filtration rate [GFR]: 52 ml/min/1...

INTRODUCTION AND OBJECTIVES: Recurrent ureteropelvic junction obstruction (UPJO) in children is an operative challenge. Minimally invasive endourological treatment options for secondary UPJO have suboptimal success rates; hence, there is a re-emergence of interest about redo pyeloplasty. The present study presented experience with laparoscopic management of previously failed pyeloplasty compared with open redo pyeloplasty in children. STUDY DESIGN: Twenty-four children with recurrent UPJO who underwent transperitoneal dismembered laparoscopic pyeloplasty were studied...

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...

OBJECTIVE: To asses if cystatin c calculated GFR can reveal CKD not detected by creatinine-based calculations in a larger prospective cohort of children with MMC. Wheel chair bound meningomyelocele (MMC) patients frequently have low muscle mass, and assessing renal deterioration based on creatinine based glomerular filtration rate is imprecise. MMC patients are also at risk for end stage renal disease. METHODS: Prospectively enrolled patients with MMC underwent annual serum creatinine and cystatin c testing...

BACKGROUND: Renal artery revascularisation procedures are usually carried out on children with renal artery stenosis from varied causes, including Takayasu's arteritis. Reports on the outcome of such procedures in children usually refer to the improvement in blood pressure, with only minimal mention of effects on renal function. OBJECTIVE: Salvageability of renal function in children who underwent renal revascularisation for Takayasu's arteritis-induced renal artery stenosis (TARAS) was the focus of this study...

The association between nonalcoholic fatty liver disease (NAFLD) and chronic kidney disease has attracted interest and attention over recent years. However, no data are available in children. We determined whether children with NAFLD show signs of renal functional alterations, as determined by estimated glomerular filtration rate (eGFR) and urinary albumin excretion. We studied 596 children with overweight/obesity, 268 with NAFLD (hepatic fat fraction ≥5% on magnetic resonance imaging) and 328 without NAFLD, and 130 healthy normal-weight controls...

BACKGROUND: Significant practice variation exists in Canada with respect to timing of dialysis initiation in children. In the absence of evidence to guide practice, physicians' perceptions may significantly influence decision-making. OBJECTIVE: The objectives of this study are to (1) evaluate Canadian pediatric nephrologists' perceptions regarding dialysis initiation in children with chronic kidney disease (CKD) and (2) determine the factors guiding practice that may contribute to practice variation across Canada...

BACKGROUND: In children, estimated glomerular filtration rate (eGFR) methods are hampered by inaccuracy, hence there is an obvious need for safe, simplified, and accurate measured GFR (mGFR) methods. The aim of this study was to evaluate different formulas and determine the optimal sampling points for calculating mGFR based on iohexol clearance measurements on blood samples drawn at two time points (GFR2p). METHODS: The GFR of 96 children with different stages of chronic kidney disease (CKD) (median age 9...

OBJECTIVE: Most predictive models of kidney disease progression have not incorporated structural data. If structural variables have been used in models, they have generally been only semi-quantitative. METHODS: We examined the predictive utility of quantitative structural parameters measured on the digital images of baseline kidney biopsies from the NEPTUNE study of primary proteinuric glomerulopathies. These variables were included in longitudinal statistical models predicting the change in estimated glomerular filtration rate (eGFR) over up to 55 months of follow-up...

BACKGROUND: Assessing the glomerular filtration rate (GFR) of paediatric patients receiving nephrotoxic chemotherapy is a vital element of clinical practice. Isotopically measured GFR is the gold standard in terms of accuracy but requires injection of tracer followed by several hours of blood tests. Estimation of GFR using creatinine is widely used but inaccurate, and there is increasing concern regarding its usage for paediatric oncology patients. Cystatin C (CysC) based equations are increasingly used in other paediatric specialities to estimate GFR, and their usefulness in paediatric oncology practice is becoming evident...

Dyslipidemia in chronic kidney disease (CKD) is usually characterized by hypertriglyceridemia. Here we studied postprandial lipemia in children and young adults to determine whether an increasing degree of CKD results in a proportional increase in triglyceride and chylomicron concentration. Secondary goals were to determine whether subnephrotic proteinuria, apolipoprotein (apo)C-III and insulin resistance modify the CKD effect. Eighteen fasting participants (mean age of 15 years, mean glomerular filtration rate (GFR) of 50 ml/min/1...

Glomerular filtration rate (GFR) is the best index for kidney function in health and disease. Knowledge of the GFR is essential for the detection (diagnosis) and monitoring of renal function during disease progression and for ensuring correct medication doses. Inulin clearance (plasma or urine) is currently considered to be the gold standard for measuring GFR, but in clinical practice the measurement of other exogenous filtration markers from the plasma often replaces that of inulin clearance. Different protocols can be used to determine the area under the plasma disappearance curve, and an understanding of these methods is important...

BACKGROUND: Combined liver-kidney transplantation (CLKT) is the accepted treatment for patients with both liver failure and progressive renal insufficiency. Long-term outcome data for CLKT in children is sparse and controversy exists as to whether simultaneous CLKT with organs from the same donor confers immunologic and survival benefit to the kidney allograft. We report the long-term renal graft outcomes of 40 patients who had simultaneous CLKT. METHODS: A retrospective analysis of kidney graft survival (time from transplantation to death, return to dialysis or last follow-up event) in all pediatric patients (age < 18 years old) who underwent CLKT from March 1994 to January 2015...
