Any Questions?
KESIMPULANSN pada anak bersifat idiopatik dan umumnya sensitif kortikosteroid. Pengobatan SN pada anak sebaiknya dimulai dengan prednison/ prednisolon yang setelah mencapai remisi, prednison / prednisolon dilanjutkan sampai mencapai dosis threshold selama 6 12 bulan.Bila terjadi relaps, apakah itu bersifat resistent atau dependen steroid maka dapat diberikan obat-obat immunosupresif lain, yang diberikan secara bersama-sama dengan steroid atau sebagai single tratment.Selain pemberian obat maka pada penatalaksanaan SN harus diperhatikan terapi penunjang..
