ABSTRAKMalondialdehida merupakan produk peroksidasi lipid yang diduga bertanggung jawab sebagai penyebab terjadinya nefropati diabetik. Penelitian ini menilai hubungan antara kadar malondialdehida serum dengan UACR dan laju filtrasi glomerulus sebagai parameter fungsi ginjal. Penelitian ini menggunakan 54 pasien diabetes melitus tipe 2 sebagai sampel (3 laki-laki dan 51 perempuan, rentang usia 42-74 tahun). Kadar malondialdehida serum diukur secara spektrofotometri menggunakan asam tiobarbiturat. Laju filtrasi glomerulus diperoleh dari nilai kreatinin serum. Kreatinin urin diukur dengan metode Jaffe dan albumin urin diukur dengan metode bromkresol hijau. Kadar malondialdehida pasien diabetes diperoleh sebesar 2,46 ± 2,58 nmol/mL; nilai UACR sebesar 42,32 ± 76,67; dan nilai laju filtrasi glomerulus sebesar 104,75 ± 46,16 (Cockroft-Gault); 89,52 ± 25,86 (MDRD study); dan 99,49 ± 46,11 (CKD-EPI). Hasil analisis hubungan antara malondialdehida dengan Cockroft-Gault (p = 0,491, r = -0,096); MDRD study (p = 0,618, r = -0,069); CKD-EPI (p = 0,611, r = -0,071); UACR (p = 0,583, r = 0,076). Ditemukan hubungan yang bermakna antara nilai UACR dengan laju filtrasi glomerulus Cockroft-Gault (p = 0,019, r = -0,318); MDRD study (p = 0,007, r = -0,361); CKD-EPI (p = 0,010, r = -0,348). Tidak ditemukan hubungan yang bermakna antara malondialdehida dengan laju filtrasi glomerulus dan UACR.
ABSTRACT, Malondialdehyde is a product of lipid peroxidation that is suspected as a cause ofdiabetic nephropathy. This study assessed the relation between malondialdehydelevel with UACR and glomerular filtration rate as renal function parameters. Thisstudy is using 54 patients type 2 diabetes mellitus as samples (3 men and 51women, age range 42-74 years). Malondialdehyde was measured byspectrophotometry using tiobarbiturat acid. Glomerular filtration rate wasobtained from serum creatinine value. Urine creatinine was measured based onJaffe method and urine albumin was measured with bromcressol green.Malondialdehyde level of diabetic patients was 2.46 ± 2.58 nmol/mL; UACR was42.32 ± 76.67; and glomerular filtration rate were 104.75 ± 46.16 (Cockroft-Gault); 89.52 ± 25.86 (MDRD study); and 99.49 ± 46.11 (CKD-EPI). Theanalysis result of the relationship between malondialdehyde and Cockroft-Gault (p= 0.491, r = -0.096); MDRD study (p = 0.618, r = -0.069); CKD-EPI (p = 0.611, r= -0.071); and UACR (p = 0.583, r = 0.076) . There were significant correlationbetween UACR and glomerular filtration rate Cockroft-Gault (p = 0.019, r = -0.318); MDRD study (p = 0.007, r = -0.361 ); CKD-EPI (p = 0.010, r = -0.348).There were no significant correlation between malondialdehyde level andglomerular filtration rate or UACR.]
