    Abstract
    Background: Steroid-resistant nephrotic syndrome (SRNS) patients tend to progress to end-stage renal disease (ESRD). The MIF high producer -173 C allele has been associated with alterations in balance between MIF and glucocorticoids; resulting in NS patients resistant to steroid therapy. In vitro studies demonstrate cytokine MIF is regulated by angiotensin II. Induction of MIF by angiotensin II affects the development of hypertension. Aim: Relationship MIF gene -173 C allele with the presence of serum MIF and plasma angiotensin II regulation for the individual SRNS is unknown. Methods: A cross-sectional study was conducted with 120 consecutive children consisting of three groups (steroid-resistant, steroid-sensitive, and well children) between November 2011 and September 2012. Data were collected consist of physical examinations, blood pressure, urinary albumin-creatinine ratio, allele of -173 gene MIF, serum MIF and plasma angiotensin II. Results: The C allele was three times more frequent in SRNS than SSNS and well children (OR 2.79 95% CI 1.13 to 6.89). Group SRNS had significantly higher serum MIF (median 31.9 (14.3 to 117.2) ng/mL) compared to the levels in other groups (p=0.04). Marked increases in median plasma angiotensin II was observed in group SRNS (median 22.7 (3.1 to 153.4) pg/mL) compared with other groups (p=0.01). Plasma angiotensin II concentrations were very weak positive correlated with serum MIF (rho= 0.27; p=0.003). Although multivariate analysis found that the C allele, systolic and diastolic hypertension,as significant variables on the risk of SRNS, but variable levels plasma angiotensin II and serum MIF significantly affect variable hypertension, if not incorporated into this models. Conclusions: C allele polymorphism of the -173 MIF gene, plasma angiotensin II and serum MIF concentrations, are higher in SRNS. The C allele, systolic and diastolic hypertension, levels of plasma angiotensin II and serum MIF are the best fit model for steroid-resistant analysis models.
     
    Latar belakang: Penderita sindroma nefrotik resisten steroid (SNRS) cenderung berlanjut ke penyakit ginjal tahap akhir. Alel C -173 gen MIF (macrophage migration inhibitory factor) berkaitan dengan gangguan keseimbangan sitokin MIF dengan glukokortikoid, sehingga penderita SN resisten terhadap terapi steroid. Studi in vitro menunjukkan sitokin MIF diatur oleh angiotensin II. Induksi regulasi MIF oleh angiotensin II memengaruhi perkembangan hipertensi. Tujuan: Hubungan alel C -173 gen MIF dengan keberadaan MIF serum dan pengaturan oleh angiotensin II plasma pada individu SNRS belum diketahui. Metode: Studi sekat lintang dilakukan pada 120 anak (steroid resisten, steroid sensitif dan anak sehat) sejak November 2011 hingga September 2012. Data yang dikumpulkan meliputi pemeriksaan fisis, tekanan darah, rasio albumin kreatinin urin, alel G atau C -173 gen MIF, MIF serum, dan angiotensin II plasma. Hasil: Frekuensi alel C tiga kali lebih tinggi pada SNRS dibandingkan dengan SNSS dan anak sehat (OR 2,79;IK 95% 1,13 sampai 6,89). Kadar MIF serum lebih tinggi pada SNRS (median 31,9 kisaran 14,3 sampai 117,2 ng/mL) dibandingkan dengan kedua grup lain (p=0,04). Kelompok SNRS menunjukkan kadar angiotensin II plasma (median 22,7 kisaran 3,1 sampai 153,4 pg/mL) lebih tinggi dibandingkan dengan grup lain (p=0,01). Korelasi angiotensin II plasma dengan MIF serum adalah korelasi positif yang sangat lemah (rho = 0,27; p=0.003). Pada analisis multivariat ditemukan bahwa alel C, hipertensi sistolik, dan diastolik sebagai variabel yang bermakna terhadap risiko SNRS. Variabel angiotensin II plasma dan MIF serum memengaruhi secara nyata terhadap variabel hipertensi, apabila tidak dimasukkan ke dalam model, sehingga tetap dipakai sebagai model terbaik. Simpulan: Frekuensi alel C, kadar angiotensin II plasma, dan MIF serum lebih tinggi pada SNRS. Alel C, hipertensi sistolik, hipertensi diastolik, kadar angiotensin II plasma dan MIF serum merupakan model terbaik untuk analisis model keberadaan resisten steroid.
