Clinicopathological characteristics and renal outcomes of childhood-onset lupus nephritis with acute kidney injury: A multicenter study
2018
AbstractObjectives: Acute kidney injury (AKI) at onset of adult systemic lupus erythematosus (SLE) is a risk factor for end stage kidney disease (ESKD). However, data on childhood-onset lupus nephritis (LN) with AKI are scarce.Methods: We retrospectively reviewed the complete files of pediatric SLE patients from 1995 to 2010. All patients underwent kidney biopsy promptly after diagnosis.Results: Thirty-six patients (10 males and 26 females) were enrolled. Mean age at diagnosis and observation period were 11.6 ± 2.4 and 8.1 ± 4.4 years, respectively. Seven patients had AKI at onset of SLE. Compared with those without AKI, patients with AKI had significantly higher proportions of pathologically proliferative LN. Only one patient with AKI progressed to ESKD without complete recovery of renal function. Overall and renal survival rates were 100and 97.2%, respectively. There was no significant difference in estimated glomerular filtration rate at the final visit (85ml/min/1.73 m2 in the AKI group vs. 103.2 ml/m...
