Preterm neonates with respiratory distress syndrome (RDS) are at increased risk of acute kidney injury (AKI). Our study aimed at determining whether serum cystatin C (sCysC) on day 3 of life (D3) can early predict AKI in preterm neonates with RDS. This prospective study was conducted on 75 preterm neonates; 50 with RDS and 25 without RDS. On D3, sCysC, serum creatinine (sCr) and blood urea nitrogen (BUN) were measured and estimated glomerular filtration rate (eGFR) was calculated. sCr and BUN levels were measured again on days 5 and 7...

BACKGROUND: Extensive data have been accumulated for adults who have undergone ABO-incompatible (ABOi)-living kidney transplantation (LKT). In contrast, available published data on pediatric recipients who underwent ABOi-LKT from the early to middle 2000s is very limited. Thus, pediatric ABOi-LKT has remained relatively rare and there is a lack of large, multicenter data. METHODS: We analyzed data from the Japanese Kidney Transplant Registry to clarify the patient and graft outcomes of pediatric recipients who underwent ABOi-LKT from 2002 to 2015...

Renal agenesis occurs in pediatric population with the incidence 1:500- 2000 children. It is more often diagnosed in boys and on the left side of the body. Renal agenesis may be isolated or it may be a part of complex malformation syndrome. Megacalycosis is a very rare anomaly of urinary tract associated with abnormal structure of the kidney pyramids. AIM: The aim of the study was to present for the first time in the medical literature the case of a girl with unilateral renal agenesis and megacalycosis...

Although anomalies in the urinary tract are the leading cause of chronic kidney disease (CKD) in the pediatric population, there are few studies focusing on etiological discrepancies between younger and older children. AIM: The aim of the study was to perform a comparative analysis of etiology of CKD in children hospitalized in the Department of Pediatric Nephrology at the Wrocław Medical University, with reference to the patients' age and gender. MATERIALS AND METHODS: The retrospective analysis considered medical records of 174 patients aged 0-18 years, diagnosed with CKD, hospitalized in our Department in the years 2011-2017...

Obstruction of urine flow at the level of the pelvo-ureteric junction (UPJO) and subsequent development of hydronephrosis is one of the most common congenital renal malformations. UPJO is associated with development of salt-sensitive hypertension, which is set by the obstructed kidney, and with a stimulated renin-angiotensin-aldosterone system (RAAS) in rodent models. This study aimed at investigating the hypothesis that i) in pediatric patients with UPJO the RAAS is activated prior to surgical relief of the obstruction; ii) in rats with UPJO the RAAS activation is reflected by increased abundance of renal aldosterone-stimulated Na+ transporters; and iii) the injured UPJO kidney allows aberrant filtration of plasminogen leading to proteolytic activation of the epithelial sodium channel gamma subunit (γ-ENaC)...

The implementation of surveillance biopsies in pediatric kidney transplantation remains controversial. Surveillance biopsies detect subclinical injury prior to clinical dysfunction, which could allow for early interventions that prolong allograft survival. We conducted a single-center retrospective cohort study of 120 consecutive pediatric kidney recipients, of whom 103 had surveillance biopsies ≤ 6 months post-transplant. We tested the hypothesis that subclinical inflammation (borderline or T cell-mediated rejection without clinical dysfunction) is associated with a 5-year composite endpoint of acute rejection and allograft failure...

Objectives: We investigated the association of fluid overload and oxygenation in critically sick children, and their correlation with various outcomes (duration of ventilation, ICU stay, and mortality). We also assessed whether renal angina index (RAI) at admission can predict mortality or acute kidney injury (AKI) on day 3 after admission. Design and setting: Prospective study, pediatric intensive care in a tertiary hospital. Duration: June 2013-June 2014. Patients: Patients were included if they needed invasive mechanical ventilation for >24 h and had an indwelling arterial catheter...

Background: IL-38 is the most recently characterized cytokine of the IL-1 family. However, its role in sepsis remains unknown. Methods: Circulating IL-38 was measured in two cohorts of adult and pediatric patients with sepsis. Using two murine models of lipopolysaccharide (LPS)-induced endotoxinemia and cecal ligation and puncture (CLP)-induced sepsis, the effects of IL-38 on survival, inflammation, tissue injury, or bacterial clearance were assessed. Results: Serum IL-38 concentrations were significantly elevated in adult and pediatric patients with sepsis relative to corresponding healthy adult and pediatric controls, respectively...

BACKGROUND: Adenovirus infection is associated with graft dysfunction and graft loss in pediatric cardiac, lung, and liver transplants in prior retrospective studies, but data in pediatric kidney transplant recipients is limited. METHODS: We conducted a prospective single-center cohort study of 75 consecutive pediatric kidney transplant recipients who underwent monthly screening for adenovirus viremia and symptom assessment for 2 years posttransplant. RESULTS: Adenovirus viremia was detected in 11 (14...

As patients with chronic kidney disease (CKD) transition from pediatric nephrology care to adult care, their kidney function is clinically assessed by estimated glomerular filtration rate (eGFR) using both pediatric and adult equations, which may not be congruent. Here we evaluated commonly used eGFR equations and directly measured iohexol GFR (iGFR) among participants between ages 18 and 26 with a diagnosis of pediatric CKD in the Chronic Kidney Disease in Children (CKiD) cohort. The bedside serum creatinine (SCr)-only equation (CKiDSCr ), the SCr-only CKD-EPI (CKD-EPISCr ), the cystatin C (Cys)-only CKD-EPI (CKD-EPICys ) and the combined SCr and Cys CKD-EPI (CKD-EPISCr-Cys ) were compared with a) 279 measured iGFRs obtained from 187 participants and b) 548 eGFRs from the SCr and Cys-based CKiD equation (CKiDSCr-Cys ) obtained from 219 participants...

The OPTN monitors progress toward strategic goals such as increasing the number of transplants and improving waitlisted patient, living donor, and transplant recipient outcomes. However, a methodology for assessing system performance in providing equity in access to transplants was lacking. We present a novel approach for quantifying the degree of disparity in access to deceased donor kidney transplants among waitlisted patients and determine which factors are most associated with disparities. A Poisson rate regression model was built for each of 29 quarterly, period-prevalent cohorts (1/1/10-3/31/17; 5 years pre-KAS, 2 years post-KAS) of active kidney waiting list registrations...

OBJECTIVE: Voiding cystourethrography (VCUG) has been considered as the gold standard technique for the diagnosis of vesicoureteral reflux (VUR). But, it requires fluoroscopic guidance which expose children to radiation. Voiding urosonography (VUS) is technically analogous to VCUG and has the major advantage of zero radiation exposure. This study aims to determine the efficacy of contrast enhanced-VUS (ce-VUS) with respect to VCUG in diagnosing VUR. MATERIAL AND METHODS: This study involves 30 children over a period of 3 years...

Pediatric kidney transplantation is lifesaving, but long-term allograft survival is still limited by injury processes mediated by alloimmune inflammation that may otherwise be clinically silent. Chemokines associated with alloimmune inflammation may offer prognostic value early post-transplant by identifying patients at increased risk of poor graft outcomes. We conducted a single-center prospective cohort study of consecutive pediatric kidney transplant recipients (<19 years). Urinary CCL2 and CXCL10 measured at 6 months post-transplant were evaluated for association with long-term eGFR decline, allograft survival, and concomitant acute cellular rejection histology...

Background: Single-center studies suggest that neonatal acute kidney injury (AKI) is associated with poor outcomes. However, inferences regarding the association between AKI, mortality, and hospital length of stay are limited due to the small sample size of those studies. In order to determine whether neonatal AKI is independently associated with increased mortality and longer hospital stay, we analyzed the Assessment of Worldwide Acute Kidney Epidemiology in Neonates (AWAKEN) database...

En bloc kidney transplants (EBK) from very small pediatric donation after circulatory death (DCD) donors are infrequent owing to the perception that DCD adversely impacts outcomes. We retrospectively studied 130 EBKs from donors ≤10 kg (65 consecutive DCD vs. 65 donation after brain death [DBD] transplants; pair-matched for: donor weight and terminal creatinine; preservation time). For DCD vs. DBD, median donor weight was 5.0 vs. 5.0 kg; median recipient age 57 vs. 48 years (p=0.006). Graft losses from thrombosis (DCD, 5%; DBD, 7%) or primary nonfunction (DCD, 3%; DBD, 0%) were similar in both groups (p=0...
