Objective To test the hypothesis that acute kidney injury (AKI) would be independently associated with increased morbidity and mortality. Study design A total of 96 consecutively cooled infants were ...reviewed retrospectively. Modified Acute Kidney Injury Network criteria were used to classify AKI based on absolute rise in serum creatinine (SCr) level from a previous trough (stage I, rise in SCr of 0.3 mg/dL or SCr 150-<200%; stage II, rise in SCr of 200-<300%; stage III, rise in SCr of ≥300%, SCr 2.5 mg/dL, or dialysis). Outcomes were mortality, duration of neonatal intensive care unit (NICU) stay, and duration of mechanical ventilation. Results AKI occurred in 36 of 96 infants (38%). Overall mortality was 7% and was higher for those with AKI, with the difference approaching statistical significance (14% vs 3% in those without AKI; P = .099). Patients with AKI stayed longer in the NICU (mean, 15.4 ± 9.3 days vs 11 ± 5.9 days; P = .014) and required prolonged mechanical ventilation (mean, 9.7 ± 5.9 days vs 4.8 ± 3.7 days; P < .001). On multivariate analysis, AKI remained predictive of prolonged duration of mechanical ventilation and prolonged NICU stay. Conclusion We used the Acute Kidney Injury Network definition for AKI in asphyxiated newborns undergoing therapeutic hypothermia to demonstrate that the incidence of AKI remains high, but lower than rates published before the advent of therapeutic hypothermia. We highlight the importance of recognizing AKI in asphyxiated newborns undergoing therapeutic hypothermia, along with the potential benefits of early recognition.
Background Data describing inpatient health care utilization in children with nephrotic syndrome and related severe complications are limited. Our goals were to describe the charges, length of stay ...(LOS), and number of hospitalizations among children, adolescents, and young adults with nephrotic syndrome. Study Design A cross-sectional analysis of the Kids' Inpatient Database (KID) database from the Healthcare Cost and Utilization Project (HCUP). The HCUP-KID is an all-payer database of hospital discharges for children, adolescents, and young adults in the United States compiled every 3 years by the Agency for Healthcare Research and Quality. Setting & Participants HCUP-KID data were obtained for the 2006 and 2009 cohort years. We identified patients by searching discharges for nephrotic syndrome International Classification of Diseases, Ninth Revision, Clinical Modification diagnosis codes. Predictor Patient demographics, disease complications in children, adolescents, and young adults hospitalized with nephrotic syndrome. Outcome Number of hospitalizations, mean charges, and LOS for children, adolescents, and young adults hospitalized with nephrotic syndrome. Results There were 6,308 hospitalization discharges in children, adolescents, and young adults with a primary or secondary diagnosis of nephrotic syndrome reported by 38 and 44 states in 2006 and 2009, respectively, representing an estimated 9,934 discharges nationally. Nephrotic syndrome resulted in an estimated 48,700 inpatient days and charges totaling $259 million. The mean charge per hospitalization was ∼$26,500 (SE, $1,100) and LOS was 5 days (SE, 0.1). 16% of discharges for nephrotic syndrome had a diagnosis code for at least one severe complication, including thromboembolism (3.6%), septicemia (3.8%), peritonitis (2.6%), pneumonia (5.4%), or diabetes (2.4%). Multivariable analysis showed age 15 years or older, race, higher socioeconomic status, acute renal failure, thromboembolic disease, hypertension, and infections predicted higher mean hospitalization charges. Limitations The HCUP-KID database collects data on a hospitalization level. Consequently, health care utilization on an individual patient level or in the outpatient environment is not possible. Conclusions We present a comprehensive description of inpatient health care utilization in children, adolescents, and young adults with nephrotic syndrome. The complications of nephrotic syndrome, including thromboembolism, infection, and hypertension, contribute significantly to these charges.
Objectives Fetuses continue to be exposed to renin angiotensin system (RAS) blockers despite their known teratogenicity and a black box warning. We hypothesized that fetopathy from in utero exposure ...to RAS blockers has a broader spectrum of clinical manifestations than described previously and that there are a variety of clinical scenarios leading to such exposures. Study design This was a retrospective study performed through the Midwest Pediatric Nephrology Consortium. Cases of RAS blocker fetopathy were identified, with determination of renal and extrarenal manifestations, timing of exposure, and the explanation for the fetal exposure. Results Twenty-four cases were identified. RAS blocker exposure after the first trimester was associated with more severe renal manifestations. Chronic dialysis or kidney transplantation was required in 8 of 17 (47%) patients with RAS blocker exposure after the first trimester and 0 of 7 patients with exposure restricted to the first trimester ( P = .05). Extrarenal manifestations, some not previously noted in the literature, included central nervous system anomalies (cystic encephalomalacia, cortical blindness, sensorineural hearing loss, arachnoid cysts) and pulmonary complications (pneumothorax, pneumomediastinum). RAS blocker exposure usually was secondary to absent or poor prenatal care or undiagnosed pregnancy. Conclusion RAS blocker fetopathy continues to be a cause of considerable morbidity, with more severe renal manifestations associated with exposure after the first trimester. A variety of significant extrarenal manifestations occur in these patients. Clinicians should emphasize the risk of fetopathy when prescribing RAS blockers to women of childbearing age.
Objective: The study objective was to determine if intraoperative peritoneal catheter placement is associated with improved outcomes in neonates undergoing high-risk cardiac surgery with ...cardiopulmonary bypass. Methods: This propensity score–matched retrospective study used data from 22 academic pediatric cardiac intensive care units. Consecutive neonates undergoing Society of Thoracic Surgeons–European Association for Cardio-Thoracic Surgery category 3 to 5 cardiac surgery with cardiopulmonary bypass at centers participating in the NEonatal and Pediatric Heart Renal Outcomes Network collaborative were studied to determine the association of the use of an intraoperative placed peritoneal catheter for dialysis or passive drainage with clinical outcomes, including the duration of mechanical ventilation. Results: Among 1490 eligible neonates in the NEonatal and Pediatric Heart Renal Outcomes Network dataset, a propensity-matched analysis was used to compare 395 patients with peritoneal catheter placement with 628 patients without peritoneal catheter placement. Time to extubation and most clinical outcomes were similar. Postoperative length of stay was 5 days longer in the peritoneal catheter placement cohort (17 vs 22 days, P = .001). There was a 50% higher incidence of moderate to severe acute kidney injury in the no-peritoneal catheter cohort (12% vs 18%, P = .02). Subgroup analyses between specific treatments and in highest risk patients yielded similar associations. Conclusions: This study does not demonstrate improved outcomes among neonates with placement of a peritoneal catheter during cardiac surgery. Outcomes were similar apart from longer hospital stay in the peritoneal catheter cohort. The no-peritoneal catheter cohort had a 50% higher incidence of moderate to severe acute kidney injury (12% vs 18%). This analysis does not support indiscriminate peritoneal catheter use, although it may support the utility for postoperative fluid removal among neonates at risk for acute kidney injury. A multicenter controlled trial may better elucidate peritoneal catheter effects.
Continuous renal replacement therapy (CRRT) is used for the symptomatic management of acute kidney injury (AKI) and fluid overload (FO). Contemporary reports on pediatric CRRT are small and single ...center in design. Large international studies evaluating CRRT practice and outcomes are lacking. Herein, we describe the design of a multinational collaborative.
The Worldwide Exploration of Renal Replacement Outcomes Collaborative in Kidney Disease (WE-ROCK) is an international collaborative of pediatric specialists whose mission is to improve short- and long-term outcomes of children treated with CRRT. The aims of this multicenter retrospective study are to describe the epidemiology, liberation patterns, association of fluid balance and timing of CRRT initiation, and CRRT prescription with outcomes.
We included children (n = 996, 0–25 years) admitted to an intensive care unit (ICU) and treated with CRRT for AKI or FO at 32 centers (in 7 countries) from 2018 to 2021. Demographics and clinical characteristics before CRRT initiation, during the first 7 days of both CRRT, and liberation were collected. Outcomes include the following: (i) major adverse kidney events at 90 days (mortality, dialysis dependence, and persistent kidney dysfunction), and (ii) functional outcomes (functional stats scale).
The retrospective WE-ROCK study represents the largest international registry of children receiving CRRT for AKI or FO. It will serve as a broad and invaluable resource for the field of pediatric critical care nephrology that will improve our understanding of practice heterogeneity and the association of CRRT with clinical and patient-centered outcomes. This will generate preliminary data for future interventional trials in this area.
