不同分期糖尿病肾病患者血清IL-18、CRP水平的变化及意义

目的探讨不同分期糖尿病肾病（DN）患者血清IL-18、C反应蛋白（CRP）水平的变化及意义。方法选择97例2型糖尿病患者,根据尿白蛋白排泄率（UAER）分为3组：正常白蛋白尿组35例、微量白蛋白尿组30例和大量白蛋白尿组32例,另选健康体检者35例作为对照组。采用ELISA法检测各组患者血清IL-18、CRP水平,并对其影响因素进行分析。结果 2型糖尿病患者血清IL-18、CRP水平明显高于对照组（P均〈0.05）,且随着UAER的增加,IL-18水平逐渐增高（P均〈0.01）。Pearson相关分析显示,血清CRP、IL-18均与病程、收缩压、糖化血红蛋白、空腹血糖、TG、TC、LDL-C、尿素氮、血肌酐、UAER呈正相关（rIL-18分别为0.766、0.628、0.568、0.388、0.375、0.400、0.512、0.516、0.698、0.792;rCRP分别为0.777、0.701、0.416、0.327、0.308、0.307、0.449、0.611、0.817、0.893,P均〈0.01）,与HDL-C呈负相关（rIL-18=-0.652、rCRP=-0.546,P均〈0.01）,且两者互呈正相关（r=0.890,P〈0.01）。结论血清IL-18、CRP与DN的发生、发展有关,两者联合检测有助于DN的早期诊断。

Changes and significances of serum IL-18,CRP level in diabetic nephropathies patients in different stages

Objective To study the serum IL-18,C-reactive protein(CRP) level changes and their significances in diabetic nephropathies patients in different stages.Methods Ninety-seven cases of type 2 diabetes were chosed,and they were divided into three groups,namely normal albuminuria group(n=35),microalbuminuria group(n=30) and proteinuria group(n=32),according to urinary albumin excretion rate(UAER).Thirty-five healthy individuals were selected as the control group.The levels of serum IL-18 and CRP were detected by...
