Idiopathic collapsing focal segmental glomerulosclerosis in pediatric patients.
The aim of this study was to evaluate the clinical outcome of our patients with idiopathic collapsing focal segmental glomerulosclerosis (FSGS) as compared to those with non-collapsing FSGS. The study included a total of 39 patients with idiopathic FSGS. Of these, 11 had collapsing FSGS and the remaining 28 were collectively grouped as non-collapsing FSGS. The mean ages, gender ratio (M:F), and percentage of African-American patients in collapsing versus non-collapsing FSGS groups were 12.7+/-3.1 and 8.9+/-5.1 years, 1.2:1 and 4.6:1, and 90.9 and 53.6%, respectively. After a mean followup period of 31.5+/-22.3 months, 8 patients (73%) with collapsing FSGS had chronic renal impairment as compared to 8 (29%) patients with non-collapsing FSGS group after a mean follow-up period of 18.7+/-12.9 months. However, the cumulated renal survival at 30 months did not reveal a significant difference. In comparison to non-collapsing FSGS, collapsing FSGS in our study was equally common in females as in males and occurred predominantly in African Americans. The outcome of our patients with collapsing FSGS at 30 months was better than in previous reports.
