BACKGROUND: In neonates, the validation of urinary biomarkers to diagnose acute kidney injury is a rapidly evolving field. The neonatal population poses unique challenges when assessing the collection, storage, and processing of urinary samples for biomarker analysis. Given this, establishing optimal and consistent sample processing in this population for meaningful use in ongoing clinical trials is important. METHODS: Urine from a cohort of 19 hospitalized neonatal intensive care unit patients enrolled in the Preterm Erythropoietin Neuroprotection Trial (Clinical Trial NCT01378273) was collected for biomarker analysis by indirect techniques using Fisher-brand cotton balls placed in the diapers...

Neonatal kidney injury is a frequent pathology, especially among premature infants. The search for effective nephroprotection requires the creation of adequate experimental models of nephropathy in newborns. In this study, we explored the development of acute kidney injury (AKI) in neonatal rats during hypoxia or administration of endotoxin. We found that 2-h hypoxia (8% O2 ) and the intraperitoneal injection of 4 mg·kg(-1) lipopolysaccharide (LPS) causes the appearance of AKI markers, such as kidney injury molecule-1 (КIM-1) and neutrophil gelatinase-associated lipocalin (NGAL) in the rat urine after 24 and 72 h of exposure...

Preterm birth occurs in approximately 10% of all births worldwide. Preterm infants have reduced nephron numbers at birth in proportion to gestational age, and are at increased risk of neonatal acute kidney injury as well as higher blood pressure, proteinuria, and chronic kidney disease later in life. Rapid catch-up growth in preterm infants, especially if resulting in obesity, is a risk factor for end-stage kidney disease among children with proteinuric renal disease. Preterm birth, however, is a risk factor not only for the infant because mothers who deliver preterm have an increased risk of having subsequent preterm deliveries as well as hypertension, cardiovascular disease, and renal disease later in life...

BACKGROUND: The definition of acute kidney injury (AKI) has evolved over the years, and three definitions have been adapted including pediatric risk injury failure, loss of kidney function (pRIFLE), Acute Kidney Injury Network (AKIN), and Neonatal Modified Kidney Disease Improving Global Outcomes (KDIGO). We sought to report the prevalence and outcome of (AKI) according to the three existing definitions in extremely low birth weight (ELBW) infants. METHODS: In a retrospective cohort study, medical records of all ELBW infants (<1000 g) admitted to our neonatal intensive care unit (NICU) between Jan 2002 and Dec 2011 were reviewed...

Normal developmental changes during postnatal life hinder the development of an AKI definition and advancement of neonatal AKI research. This report summarizes the expert discussion at a National Institute of Diabetes and Digestive and Kidney Diseases sponsored neonatal AKI workshop, on knowledge gaps in defining neonatal AKI. The most important knowledge gaps and neonatal AKI definition research recommendations were agreed upon and defined. Several challenges were identified in defining neonatal AKI using serum creatinine (SCr) and urine output criteria applied in adults and children...

OBJECTIVE: Acute kidney injury (AKI) is a frequent complication after cardiopulmonary bypass (CBP) for cardiac surgery in neonates. It is unclear if exposure to computed tomography angiography (CTA) in the preoperative period increases the risk of AKI. We hypothesized a short interval between CTA and CPB surgery would be associated with higher rates of AKI in infants. DESIGN: In this single center retrospective review of patients between 2012 and 2015, neonates less than one month old were analyzed if they had CTA prior to cardiac surgery with CPB...

BACKGROUND: Neonatal acute kidney injury (AKI) is common and is associated with poor outcomes. New criteria for the diagnosis of AKI were introduced based on the increase in serum creatinine (SCr) levels and/or reduction of urine output (UOP). Yet, there is no generally accepted opinion so far, which criteria (whether SCr, UOP, or their combination) are the most appropriate to diagnose neonatal AKI. METHODS: The retrospective study included 195 prematurely born neonates who fulfilled all inclusion criteria (with at least two SCr measurements)...

Atypical hemolytic uremic syndrome (aHUS) is a rare syndrome characterized by microangiopathic hemolytic anemia, thrombocytopenia, and acute kidney injury that is usually caused by complement dysregulation. Complement factor H (CFH) is a regulator of the complement system produced in the liver, and CFH gene mutations are the most frequent causes of aHUS. To date, the therapeutic options for aHUS with CFH mutations have consisted of plasma infusions, plasma exchange, kidney transplantation, isolated liver transplantation, or combined liver and kidney transplantation...

Treating acute kidney injury (AKI) in newborns is often challenging due to the functional immaturity of the neonatal kidney. Because of this physiological limitation, renal replacement therapy (RRT) in this particular patient population is difficult to execute and may lead to unwanted complications. Although fluid overload and electrolyte abnormalities, as seen in neonatal AKI, are indications for RRT initiation, there is limited evidence that RRT initiated in the first year of life improves long-term outcome...

A prospective national cohort study was undertaken to collect data on all cases of pediatric (under 18 yrs of age) acute kidney injury (AKI) identified by a biochemistry-based electronic alert using the Welsh National electronic AKI reporting system. Herein we describe the utility and limitation of using this modification of the KDIGO creatinine-based system data set to characterize pediatric AKI. Of 1,343 incident episodes over a 30-month period, 34.5% occurred in neonates of which 83.8% were AKI stage 1. Neonatal 30-day mortality was 4...

BACKGROUND: Early surgical correction of congenital heart malformations in neonates and small infants may be complicated by acute kidney injury (AKI), which is associated with higher morbidity and mortality rates, especially in patients who require dialysis. Glomerular filtration rate (GFR) is considered the best measurement of renal function which, in neonates and infants, is highly dependent on heart function. OBJECTIVES: To determine whether measurements of creatinine clearance after open heart surgery in neonates and young infants can serve as an early indicator of surgical success or AKI...

OBJECTIVES: Acute kidney injury (AKI) is defined as a decrease in glomerular filtration rate with an increase in serum creatinine (sCr). Perinatal asphyxia (PNA) may be etiological factor for AKI with oxidative stress also implicated. Paraoxonase 1 (PON1) activity has been reported to be decreased in renal disease. The aim of our study was to evaluate paraoxonase 1 (PON1) activity and oxidative stress during the first hours and first days of life and to determine if these parameters could discriminate neonates having AKI from those who do not...

Treatment options for adenovirus infection in immunocompromised children are limited. Nephrotoxicity has been associated with cidofovir use, but the rate of cidofovir-associated nephrotoxicity in pediatric patients is unclear. In a retrospective review of patients with adenovirus infection treated with cidofovir, neonates (n = 5) had higher viral loads and shorter times to renal insufficiency than older children (n = 24). Higher weekly doses of cidofovir were associated with greater increases in creatinine levels...
