title: Focal glomerulosclerosis in children: correlation of histology with prognosis.
abstract: The clinical and pathologic data of 32 nephrotic children diagnosed as having focal glomerulosclerosis were retrospectively analyzed to determine what factors were responsible for progression to renal failure in 12 of these children. The patients were classified into three groups based on the histologic findings in their initial renal biopsies: Group I (n = 19) had a combination of global and segmental lesions; Group II (n = 8) had only globally sclerotic or obsolescent glomeruli; and Group III (n = 5) had only segmentally sclerosed glomeruli. Ten of the 12 patients with end-stage renal failure came from Group I and two from Group II. The median period from recognition of symptoms to renal failure was four years. Clinical features were of little prognostic value. However, comparison of the histopathologic data of the ten patients in Group I with renal failure (Group Ia) and Groups Ib, II, and III revealed that the risk of progressing to renal failure was significantly higher in patients having greater than 20% of their glomeruli involved by both global and segmental lesions (P = 0.005). Furthermore, patients in Group I and III had a lower probability of responding to treatment as compared to patients in Group II (P less than 0.025).
