摘要
目的 探讨2型糖尿病患者血清胆红素与尿白蛋白水平之间的相关性.方法 选取2型糖尿病患者686例,根据尿白蛋白排泄率(UAER)水平将其分为正常白蛋白尿组(UAER<20 μg/min,329例)、微量白蛋白尿组(20 μg/min≤UAER< 200 μg/min,297例)和显性白蛋白尿组(UAER≥200 μg/min,60例),比较3组间血清胆红素水平的差异,采用Spearman相关分析和Stepwise多元逐步回归分析评价胆红素对UAER的影响.结果 显性白蛋白尿组患者的总胆红素(TBIL)、直接胆红素(DBIL)和间接胆红素(IBIL)水平[分别是(8.4±3.7)μmol/L、(2.3±1.2)μmol/L和(6.1±3.0) μmol/L]较微量白蛋白尿组[分别是(10.6±4.8) μmol/L、(3.1±1.7)μmol/L和(7.4±3.5) μmol/L]和正常白蛋白尿组[(11.3±6.3)μmol/L、(3.5±2.8) μmol/L和(7.8±4.3) μmol/L]显著降低(P<0.01或P<0.05).TBIL(r=-0.084,P=0.027)、DBIL(r=-0.110,P=0.005)与UAER呈显著负相关.结论胆红素可能是2型糖尿病肾病的保护性因素,应重视胆红素的抗氧化作用.
Objective To explore the relationship between serum bilirubin and urinary albumin in patients with type 2 diabetes. Methods 686 patients with type 2 diabetes were divided into three groups based on urine albumin excretion rate (UAER) levels. Serum bilirubin levels of each group were determined. Correlation between bilirubin and UAER was performed using Spearman' s rank correlation and stepwise multiple regression analysis. Results The total bilirubin ( TBIL), direct bilirubin (DBIL) and indirect bi|iruhin(IBIL) levels in macroalbuminuria group were (8.4 ± 3.7 ) μmol/L, (2.3 ± 1.2 ) μmol/L and( 6. l ± 3.0 )μmol/L ,which in microalbuminuria group were (10.6 ± 4.8 )μmol/L, (3.1 ±1.7 ) μmol/L and ( 7.4 ± 3.5 ) μmol/L, which in normal albuminuria group were ( 11.3 ± 6.3 ) μmol/L, ( 3.5 ± 2.8 ) μmol/L and ( 7.8 ± 4.3 ) μmol/L. There were significant differences among these three groups ( P 〈 0.01-0.05 ). TBIL ( r = - O. 084, P = 0. 027 ), DBIL ( r = - 0. 110, P = 0. 005 ) and UAER was a significant negative correlation. Conclusion Bilirubin may be a protective factor for type 2 diabetic nephropathy. The bilirubin antioxidant effects should be taken seriously.
