Profile of Acute Kidney Injury in Hospitalized Children with Idiopathic Nephrotic Syndrome

Abstract

Objective

To determine the incidence, risk factors and outcome of acute kidney injury (AKI) in hospitalized children with nephrotic syndrome.

Methods

All consecutive hospitalized children (aged 1–14 years) with diagnosis of nephrotic syndrome between February 2016 and January 2017 were enrolled for the study. Children (aged 1–14 years) with features of nephritis, underlying secondary causes of nephrotic syndrome as well as children admitted for diagnostic renal biopsy and intravenous cyclophosphamide or rituximab infusion were excluded.

Results

A total of 73 children (81 admissions) were enrolled; incidence of AKI was 16% (95% CI, 9-23). On multivariate logistic regression analysis, furosemide infusion was observed as an independent risk factor for acute kidney injury (OR 23; 95% CI, 3-141; P<0.001). Out of 13 children with AKI, three died.

Conclusions

Acute kidney injury in hospitalized children with nephrotic syndrome has high risk of mortality. Children receiving furosemide infusion should be closely monitored for occurrence of acute kidney injury.
