Any Questions?21KESIMPULANSN 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..22Sindrom nefrotik relaps frekuen atau dependen steroidPrednison FD RemisiDiturunkan sampai dosis treshoid 0,1-0,5 mg/kgBB AD6-12 bulanPrednison AD + CPARelaps padaPrednison > 0,5 mg/kgBB ADLevamisol 2,5 mg/kgBB AD(4-12 bulan)Relaps pada prednison > 1 mg/kgBB ADatauEfek samping steroid meningkatCPA 2-3 mg/kgBB8-12 mingguRelaps prednison standarRelaps pada prednison > 0,5 mg/kgBB ADSiklosporin 5 mg/kgBB/hariselama 1 tahunGambar.

ACUTE POST STREPTOCOCCAL GLOMERULONEPHRITISBEBERAPA ISTILAHGlomerulonefritis Akut (GNA) : Suatu bentuk proses proliferasi dan inflamasi glomeruli yang didahului oleh suatu proses infeksi dan terjadi secara akut.( contoh : GNAPS )
Sindrom Nefritik Akut (SNA ) :Suatu kumpulan gejala-gejala klinik berupa proteinuria, hematuria azotemia, redblood cast( torak eritrosit ), oligouria dan hipertensi (PHAROH)
ISTILAH GNA dan SNAGNA lebih bersifat histologik ( proliferasi dan inflamasi sel-sel glomerulus)
* SNA lebih bersifat klinik ( PHAROH)
Salah satu bentuk SNA/GNA adalah GNAPS
Proliferasi dan inflamasi glomeruli Sekunder oleh mekanisme imunologik Antigen: streptokokus B hemolitikus grup A
GNAPS
1. Angka kejadian Lebih sering umur 6-7 thn, jarang < 3 thn Laki laki > perempuan (2:1) 10- 12 % kasus infeksi strept. hemolitikus grup A Kaplan: 50% kasus asimtomatik pd epidemi GNAPS didahului ISPA atau piodermi
2. Etiologi Streptokokus hemolitikus grup A (tipe M) NEFRITOGENIK Faringitis (serotipe tersering 12, lalu 1,3,4,6,25) Piodermi (serotipe tersering 49, lalu 2,53,55, 56,57,58,60

URIN:Hematuri, warna kemerah-merahan atau seperti air dagingProteinuri : kualitatif dan kuantitatif> 6 bulan proteinuri persisten biopsi ginjal

Diagnosis GNAPS
PENGOBATANANTIBIOTIK :Bila dijumpai tanda-tanda infeksi
PENGOBATAN SIMTOMATIK : - Diuretik : + oligouri + edema pulmonum - AntihipertensiKOMPLIKASI YANG TERJADI PADA GNAPS DAN SN:
