Abstract:
Objective To investigate the relationship between serum levels of growth differentiation factor-11(GDF-11)and S100 calcium binding protein A4(S100A4)and the severity and disease outcome in diabetic nephropathy(DN)patients.Methods A total of 95 DN patients admitted to the hospital from May 2021 to January 2023 were selected as the study group,and 110 healthy people were selected as the healthy group.The DN patients were divided into mild group(n=66)and severe group(n=29)according to the severity of the disease.The patients were followed up for half a year after discharge,and were divided into good prognosis group(n=64)and poor prognosis group(n=31)according to the prognosis.Serum GDF-11 and S100A4 lev-els were detected by enzyme-linked immunosorbent assay.Spearman rank correlation analysis was used to ex-plore the relationship between serum GDF-11,S100A4 levels and the severity of the disease.Receiver operat-ing characteristic(ROC)curve was used to evaluate the predictive value of serum GDF-11 and S100A4 for dis-ease outcome in DN patients,and multivariate Logistic regression was used to analyze the influencing factors of disease outcome in DN patients.Results The levels of serum GDF-11 and S100A4 in mild group and severe group were higher than those in healthy group,and those in severe group were higher than those in mild group(P＜0.05).Serum GDF-11 and S100A4 levels were positively correlated with the severity of DN patients(P＜0.05).The good prognosis group had significantly lower serum levels of GDF-11 and S100A4 than the poor prognosis group(P＜0.05).The area under the curve(AUC)of serum GDF-11 and S100A4 in predicting the outcome of DN patients was 0.785 and 0.839,respectively,and the AUC of combined prediction was 0.902.The proportion of type 2 diabetes(T2DM)duration,glomerular grade Ⅲ-Ⅳ,interstitial inflammation score 2,interstitial fibrosis and tubular atrophy(IFTA)score 2-3 points,estimate glomerular filtration rate＜60 mL/(min·1.73 m2)and the levels of total cholesterol,triglyceride,low-density lipoprotein choles-terol,24 h urinary protein,glycosylated hemoglobin,C-peptide,hematocrit,and erythrocyte sedimentation rate in the good prognosis group were higher than those in the good prognosis group(P＜0.05).Multivariate Lo-gistic regression analysis showed that the duration of T2DM ≥12.0 years,IFTA score ≥2 points,GDF-11≥700.82 ng/mL,S100A4 ≥ 211.53 ng/L were risk factors for poor prognosis in DN patients(P＜0.05).Conclusion The levels of serum S100A4 and GDF-11 are highly expressed in patients with diabetes mellitus,and are related to the severity and outcome of the disease,which are expected to be potential markers for eval-uating the condition and prognosis of diabetes mellitus.
