Abstract:
Objective To investigate the diagnostic value of combined detection of serum secreted frizzled-related protein 5(SFRP5),fibroblast growth factor-21(FGF-21)and kidney injury molecule-1(KIM-1)in di-abetic nephropathy(DN).Methods Patients with DN(n=53)who were treated in Jingnan Medical District,General Hospital of the People's Liberation Army from December 2021 to December 2023 were selected as the study group,and patients with simple diabetes(n=53)were selected as the control group.The levels of ser-um SFRP5,FGF-21 and KIM-1 were detected by enzyme-linked immunosorbent assay.Multivariate Logistic regression analysis was used to analyze the factors affecting the occurrence of DN.The receiver operating char-acteristic(ROC)curve was drawn to analyze the efficacy of serum SFRP5,FGF-21 and KIM-1 levels in the di-agnosis of occurrence of DN.Results Compared with the control group,the levels of fasting blood glucose,u-rine albumin/urine creatinine,urine microalbumin,FGF-21 and KIM-1 in the study group were significantly increased(P<0.05),while the levels of glomerular filtration rate and SFRP5 were significantly decreased(P<0.05).The area under the curve(AUC)of serum SFRP5,FGF-21 and KIM-1 in the diagnosis of occur-rence of DN was 0.977,which was larger than that of each index alone(Zthree combination-SFRP5=2.759,P=0.006,Zthree combination-FGF-21=2.936,P=0.003,Zthree combination-KIM-1=3.104,P=0.002).The sensitivity of combined diagno-sis was 96.23%,the specificity was 88.68%,and the Youden index was 0.849.SFRP5,FGF-21,KIM-1,fast-ing blood glucose,glomerular filtration rate,urine albumin/urine creatinine,urine microalbumin were the in-fluencing factors of occurrence of DN(P<0.05).Conclusion The serum SFRP5 level is decreased and FGF-21 and KIM-1 levels are increased in DN patients.The combination of the three has the best diagnostic effi-ciency for occurrence of DN.
