ABSTRACT
Purpose : This multicenter collaboratory study was conducted to see the therapeutic efficacy and side effect of cyclosporine A (Cipol-$N^{(R)}$, Chong Kun Dang) on children with idiopathic nephrotic syndrome who experienced frequently relapsing (FR), steroid dependent (SD), or steroid resistant (SR) pattern. Patients and methods : Thirty-nine children with SD/FR NS and 3 children with SR NS were enrolled in the study. After induction of remission (SD/FR NS) with steroid or after 4 weeks of steroid therapy (SR NS), cyclosporine A was started in a dose of 4-5 mg/Kg/day in two divided dose and steroid (prednisolone or equivalent dose of deflazacort) was tapered slowly. During 16 weeks of study period, monthly check up of physical examination and various laboratory tests including BUN, creatinine, Ccr and cyclosporine blood level were done.
Results : Out of 39 children with SD/FR NS, 35($89.7%$) maintained sustained remission and at 4 weeks after therapy, values of serum protein, albumin, cholesterol, and 24 hours urinary protein excretion showed normal values. Two out of 3 children with SR NS showed and sustained remission with cyclosporine A therapy. Side reaction to cyclosporine A therapy showed hypertrichosis in 8 cases and hyperuricemia in 5 cases. However, other laboratory tests including CBC, liver profile, BUN, creatinine and GFR (creatinine clearance utilizing 24 hour urine) did not show any abnormalities during the 16 weeks of study period.
Conclusion : Cyclosporine A (Cipoi-$N^{(R)}$ Chong Kun Dang) can be utilized quite effectively on children with SD/FR or SR NS and further trial of cyclosporine A on long-term basis (1-2 year period) is needed to determine it's efficacy and side effect (especially nephrotoxicity) of long-term administration of cyclosporine A.
