Acute kidney injury (AKI) is common in neonates admitted to the neonatal intensive care unit (NICU). AKI is associated with increased morbidity and mortality and a greater long-term risk of chronic kidney disease. ⋯ AKI occurred in more than half of all NICU admissions, was associated with an increased risk of mortality, and had a higher incidence among smaller and sicker infants. Therefore, close monitoring of renal function during hospitalization and after discharge is warranted in such infants.

This study aims to describe the cardiovascular manifestations in children with autosomal dominant polycystic kidney disease (ADPKD) and detect their relation with kidney disease and type of gene mutation. ⋯ High PWV and increased cIMT indicating arterial stiffness and hypertrophic vasculopathy may be present in children with ADPKD regardless BP status, and prior to GFR decline, suggesting that vascular disease precedes chronic kidney disease in ADPKD.

To define those children who develop acute kidney injury (AKI) within 48 h of admission from the emergency department (ED) and ascertain patient-related factors in the ED associated with AKI. ⋯ One in 10 children who had SCr measured and were admitted to a tertiary pediatric hospital had AKI on or within 48 h of presentation. Inherent characteristics, identifiable in the ED, are associated with an increased risk of AKI. Future research should focus on improving AKI recognition in the ED by the development of a risk stratification tool.

Hemolytic uremic syndrome (HUS) is a clinical syndrome characterized by hemolytic anemia, thrombocytopenia, and acute kidney injury. Atypical hemolytic uremic syndrome (aHUS) is a devastating disease with significant mortality and high risk of progression to end-stage kidney disease. It is mostly caused by dysregulation of the alternative complement pathway. Cobalamin C (Cbl C) defect is a genetic disorder of cobalamin metabolism and is a rare cause of HUS. ⋯ To the best of our knowledge, our patient is the first to have Cbl C defect-HUS accompanied by complement dysregulation, who responded well to eculizumab therapy.

We previously reported that children undergoing cardiac surgery are at high risk for long-term chronic kidney disease (CKD) and hypertension, although postoperative acute kidney injury (AKI) is not a risk factor for worse long-term kidney outcomes. We report here our evaluation of renal injury biomarkers 5 years after cardiac surgery to determine whether they are associated with postoperative AKI or long-term CKD and hypertension. ⋯ Postoperative pediatric AKI is not associated with urinary kidney injury biomarkers 5 years after surgery. This may represent a lack of chronic renal injury after AKI, imprecise estimation of the glomerular filtration rate, the need for longer follow-up to detect chronic renal damage, or that our studied biomarkers are inadequate for evaluating subclinical chronic renal injury.
