Abstract

Background: Idiopathic steroid-resistant nephrotic syndrome (ISRNS) is rare and represents a significant therapeutic dilemma for paediatricians and paediatric nephrologists.
Aim: To analyze characteristics of the ISRNS in the child.
Methods: Retrospective study of 20 cases of ISRNS enrolled in paediatric department of nephrology in Sahloul hospital (Tunisia) between June 1993 and December 2007 (14 years period).
Results: There were eight girls and 12 boys (mean age: 5.8± 3.7 years) originating from the center or the south of Tunisia. Eight of them had a minimal-change disease (MCD), 11 a focal and segmental glomerulosclerosis (FSGS) and one a mesangioproliferative glomerulonephritis (MePGN). In this group, no family form could be identified. All patients were treated by cyclosporine associated with low dose of steroid. We noted a complete remission (CR) in nine cases, partial remission (PR) in three cases and no response to cyclosporine in eight cases. Among patients with CR, six presented MCD and three a FSGS. In this group, we observed relapse of nephrotic syndrome in six cases. End stage renal disease (ESRD) was noted in 10 patients of which five not responded to cyclosporine, two initially having presented a RC and three having since the beginning a PR. Among them, two only could be grafted; one relapses on transplant was observed with a single patient initially presenting a secondarily transformed MePGN in FSGS.
Conclusion: Our study confirms the clinical, histological and evolutive heterogeneity of idiopathic steroid-resistant nephrotic syndrome. Although there is any therapeutic consensus in this domain, cyclosporine remains indicated in first intention in sporadic forms of ISRNS. On the other hand, renal transplantation constitutes the only therapeutic alternate in genetic forms that constantly evolve at ESRD.
