Idiopathic collapsing glomerulopathy (ICG) is a clinically and pathologically distinct variant of focal segmental glomerulosclerosis, characterized clinically by rapid progression of renal insufficiency, a male and African-American racial predominance, and pathologically by segmental glomerular collapse, visceral epithelial cell hypertrophy and hyperplasia, and the absence of endothelial tubuloreticular inclusions. Pathologically similar lesions have been reported in adult and pediatric patients with human immunodeficiency virus (HIV) infection and/or intravenous (IV) drug abuse. Most patients with ICG who have been reported in the literature are adults. Six children with ICG were retrospectively identified (two from East Carolina University, four from University of North Carolina-Chapel Hill). Clinical data and renal biopsy findings were reviewed for all patients. All six patients were male; five African-American and one Hispanic. Ages ranged from 2 to 17 years (mean 12 years). Steroid-resistant nephrotic syndrome was the presenting clinical finding. Average 24-h urine protein excretion was 6.3 g (range 3.2-15 g). Five patients were serologically negative for HIV infection (one patient not tested) and none had a history of IV drug abuse or known HIV risk factors. Progression to end-stage renal insufficiency in two patients within 1 year of biopsy required renal transplantation, and within 1 month of biopsy one patient required dialysis. We report a series of pediatric patients with ICG, an aggressive variant of focal segmental glomerulosclerosis. ICG in children is similar clinically and pathologically to this disease in adult patients. |
