ObjectivesTo determine the incidence, etiology, short term outcome and predictors of mortality in hospitalized children aged 1 mo to 13 y with Acute Kidney Injury (AKI).MethodsThis prospective observational study was conducted in the pediatric wards and the pediatric intensive care unit (PICU) of a tertiary hospital in southern India, to study the clinico-etiological profile of AKI (defined according to the Acute Kidney Injury Network criteria). From June 2010 through March 2011, 2376 children were included in the study.ResultsThe incidence of AKI was 5.2 % in the pediatric wards and 25.1 % in the PICU. AKI occurred in association with infections (55.4 %), acute glomerulonephritis (16.9 %), cardiac disease (4.8 %), envenomations (4.2 %) and hemolytic uremic syndrome (3.6 %). Pneumonia constituted 26.1 % of the infections. Tropical febrile illnesses (dengue, scrub typhus, enteric fever, cholera, tuberculosis, malaria and leptospirosis) constituted 15.6 % of children with AKI. Dialysis was required in 14.5 % of patients; mortality was 17.5 %. A significant proportion of children (17.5 % of survivors) had partial renal recovery at discharge. On multivariate logistic regression, dysnatremia and meningoencephalitis were independent predictors of mortality in AKI.ConclusionsThe incidence of AKI is high in the patient population, including the non-critically ill children. AKI continues to be associated with adverse outcomes. Presence of dysnatremia and meningoencephalitis are poor predictors of outcome in AKI.
