ranged between 2 and 72 months (14AE14.1). Overall response to the second line of treatment was observed among majority of patients (91.7%). Renal biopsy was performed in 45.8% of patients. Concerning side effects of steroid sparing agents, electrolytes disturbances and hypertension were reported by two (8.3%) and one (4.2%) patients respectively. Duration of remission was significantly longer among patients treated with cyclosporine (48AE33.9 months) compared to other lines of treatment, p<0.001. On the other hand, hypertension was only reported among patients treated with cyclosporine, p=0.003. Conclusions: The overall response of children with SDNS and FRNS to the second line agents was significant, with favorable longer remission free period with Cyclosporine use with no major side effects. Our results affected by the retrospective design of the study, as well as the small sample size. Therefore larger scale study with prospective design is highly encouraged.
