Abstract:
Objective To analyze the relationship between the serum CysC,lipoprotein(a) [Lp(a)] and the urinary microalbumin/creatinine ratio in elderly type 2 dibetic (T2CM) patients.Methods A total of 102 elderly patients with T2CM who were treated in our hospital from December 2014 to December 2015 were selected.The patients were divided into diabetic nephropathy(DN) group(mALB≥20 μg/min,48 cases)and non-diabetic nephropathy(NDN) group (mALB<20 μg/min,54 cases) according the levels of urinary mALB,while 30 cases of healthy controls were selected from physical examination center.The biochemical indexes,CysC,Lp(a) and UACR were detected among all cases.The correlation between indexes and UACR was analyzed by Pearson correlation analysis,risk factors for UACR among DN patients were analyzed by Logistic regression analysis.Results There were significant differences in levels of low density lipoprotein cholesterol(LDL-C),Lp(a),urea,creatinine,fasting blood glucose(FBG),glycosylated hemoglobin(HbA1c),Cysc,and UACR among these groups (P<0.05).No correlation between CysC、Lp(a) and UACR was found in normal-control group and non-diabetic nephropathy group.In diabetic nephropathy group,there was a positive correlation between CysC,Lp(a) and UACR(r=0.658,P<0.01;r=0.525,P<0.05).The Logistic regression analysis showed that diabetes duration,CysC,Lp(a) were independent risk factors for UACR(P<0.05).Conclusion In patients with diabetic nephropathy,CysC,Lp(a) are positively correlated with UACR,and CysC is a sensitive index that reflect early renal damage in T2DM patients.Lp(a) level is one of the independent risk factors for UACR,which can reveal the kidney damage in DN patients.
