About

The kidneys of neonates are particularly susceptible to hypoperfusion because of the physiologic characteristics of neonatal kidneys, including high renal vascular resistance, high plasma renin activity, low glomerular filtration rate (GFR), decreased intracortical perfusion rate, and decreased reabsorption of sodium in proximal convoluted tubules in the first day of neonatal life (1) Acute kidney injury (AKI) occurs commonly in the neonatal intensive care unit (NICU) and is associated with increase morbidity and mortality. Furthermore, those who develop neonatal AKI may be at increased risk for the development of chronic kidney disease (CKD). With ongoing study, the definition of neonatal AKI has evolved and been standardized, improving our ability to quantify and describe the epidemiology and outcomes associated with neonatal AKI (2) Acute kidney injury (AKI) is defined as kidneys' inability to excrete nitrogenous waste products and maintain fluid and electrolyte homeostasis. It is fairly common in newborn population and is a major contributing factor of neonatal mortality and morbidity (3) Acute kidney injury (AKI), frequently involving patients admitted to the neonatal intensive care unit (NICU), is associated with poor outcomes and affects 18-70% of critically ill neonates. Although the real incidence of AKI in neonates is uncertain, with wide and various ranges, due to several definitions and diagnostic methods, more immature and ill neonates are characterized by the highest risk of AKI (4) Patients with congenital heart disease, perinatal asphyxia, premature birth or a low birth weight, and necrotizing enterocolitis, as well as neonates who receive nephrotoxic medications or require extracorporeal life support, represent high-risk populations. According to the Worldwide Acute Kidney Injury Epidemiology in Neonates (AWAKEN) data, one episode of AKI, related to an increased length of hospitalization and mortality rate, was observed in 30% of critically ill neonates (5) To apply personalized therapeutic approaches to AKI, an adequate and early diagnosis could reduce or avoid subclinical and precocious renal injuries and their related effects, requiring chronic follow-up, as suggested by the Clinical Practice Guidelines for Acute Kidney Injury (KDIGO), recommending a nephrological evaluation after three months, if an AKI event occurs (6)

The precocious diagnosis of AKI based on urinary output and serum creatinine (sCr) levels represents one of the hardest challenges in clinical practice. Several biomarkers and clinical scores were assessed to predict neonatal AKI, to identify the stage of injury and not the damage, to anticipate late rises in sCr values and to reveal an already compromised renal function (7)
