Abstract: Objective To investigate the predictive values of serum cystatin C(Cys-C),urinary β2-microglobulin(β2-MG),and urinary transferrin(UTRF)in diabetic nephropathy.Methods Forty-eight patients with diabetic nephropathy(DN)admitted to the Department of Endocrinology and Metabolic Diseases of the First Hospital of China Medical University from February to May 2021 were selected as the DN group,while 50 patients with diabetes mellitus(DM)alone were selected as the DM group. Their clinical data,which included serum triglycerides(TG),serum total cholesterol(TC),serum high-density lipoprotein cholesterol(HDL-C),serum low-density lipoprotein cholesterol(LDL-C),serum apolipoprotein A-1(ApoA-1),serum apolipoprotein B(ApoB),serum lipoprotein a[ LP(a) ], cystatin C(Cys-C), serum uric acid(UA),plasma glycosylated hemoglobin(HbA1c),urinary β2-MG,and UTRF were collected and compared. Multi-factor logistic regression was used to analyze the factors influencing DN. The predictive values of Cys-C, β2-MG,and UTRF on DN were analyzed using receiver operating characteristic(ROC)curves.Results The differences in Cys-C, β2-MG,and UTRF levels and the positivity rates between the two groups were statistically significant(all P < 0.05). Multi-factor logistic regression analysis showed that Cys-C and UTRF levels were independent risk factors for DN(all P < 0.05). The results of the ROC curve analysis showed that Cys-C, β2-MG,and UTRF had high diagnostic values for DN,with combined Cys-C and UTRF having the highest diagnostic value(area under curve = 0.909,95% CI:0.850-0.967,sensitivity=0.917,specificity= 0.760). Conclusion Cys-C, β2-MG,and UTRF can reflect the severity of kidney damage in patients with DM. Cys-C and UTRF are independent risk factors for DN. Cys-C, β2-MG,and UTRF levels,all have predictive values for DN,with combined Cys-C and UTRF having the greatest diagnostic significance.
