Original article



Information on long-term renal outcome of pediatric glomerulonephritis associated with crescent formation is limited. A single center retrospective study was conducted to assess long-term renal survival and to determine whether the 2010 classification for antineutrophil cytoplasmic antibody (ANCA)-associated glomerulonephritis can predict renal outcome in pediatric glomerulonephritis associated with crescent formation.


Biopsy and clinical data of children, aged ≤ 18 years with ≥ 10 glomeruli and ≥ 10% crescentic glomeruli during January 1998 to December 2015, were reviewed. Biopsies were classified according to the 2010 classification into focal, crescentic, mixed, and sclerotic classes. The clinical endpoint was end-stage renal disease (ESRD).


Of 72 children, 14 patients (19.4%) had positive ANCA. The biopsy indication was rapidly progressive glomerulonephritis in 38 patients (52.8%) and 22 patients (30.6%) required dialysis at onset. Lupus nephritis was the most common diagnosis (43.1%), followed by IgA nephropathy/Henoch–Schoenlein purpura (HSP) (22.2%). ESRD occurred in 18 patients (25%) and the risk of ESRD differed among the histological classifications (p < 0.001). Dialysis at onset and sclerotic class was independent predictors of ESRD in an adjusted model. The risk of ESRD was four-fold higher in patients requiring dialysis at onset and 7.7-fold higher in sclerotic patients than in crescentic patients.


The probability of ESRD was substantial in pediatric glomerulonephritis associated with crescent formation. The 2010 classification is useful for establishing long-term renal prognosis. Future research is required to validate whether histological classification could be a determinant in therapeutic guideline modification, since long-term renal prognosis is different in each class.
