Serum cystitis C and urinary transferrin and urinary α1 microglobulin combined detection in diagnosis of early diabetic kidney disease / 国际检验医学杂志

ABSTRACT

Objective To explore the diagnostic value of serum cystitis C(CysC),urinary transferrin (UTRF)and urinary α1 microglobulin(α1MG)in the diagnosis of early diabetic nephropathy(DKD).Methods Totally 165 patients with diabetic mellitus treated in the hospital from January 2016 to January 2017 were selected,and then assigned to diabetic mellitus group(DM group)and diabetic kidney disease group(DKD group)based on urinary albumin excretion rate(UAER).83 healthy people were enrolled and assigned to con-trol group.The level of serum CysC,serum creatinine(SCr)and blood urea nitrogen(BUN)were detected by automatic biochemical analyzer,the level of UTRF,α1MG and microalbuminuria(MALB)were detected by lmmunoturbidimetry and then compare the variance in each group.Results Compared with the control group and DM group,the level of serum CysC,UTRF,α1MG and MALB were significantly increased in DKD group (P<0.05);The level of SCr and BUN in DKD group were increased but had no statistical significance com-pared with DM group(P> 0.05).Meanwhile,the positive detection rate of serum CysC,UTRF and α1MG were significantly higher than SCr and BUN(P<0.05).Serum Cys C,UTRF and α1MG showed positive cor-relation with MALB,SCr and BUN,the level of serum Cys C also showed a positive correlation with α1MG. The sensitivity of serum Cys C,UTRF and α1MG combined detection was 92.9%,which significantly higher than single maker detection(P<0.05).Conclusion The combined detection of serum cystitis C,urinary trans-ferrin and urinary α1 microglobulin have important value in the diagnosis of early diabetic kidney disease.
