Correlation of Serum Adropin and Cystatin C with Diabetic Nephropathy
Objective To investigate the relationship between serum Adropin level and cystatin C(CysC)level and DKD in patients with diabetic kidney disease(DKD),and to provide an effective basis for the clinical diagnosis and treatment of DKD.Methods The clinical data of 219 patients with type 2diabetes mellitus(T2DM)admitted to Zhengzhou Central Hospital of Zhengzhou University from September 2022 to June 2023 were retrospectively analyzed,they were divided into normal albuminuria group(n=109),microalbuminuria group(n=65),and massive albuminuria group(n=45)according to the urinary albumin/creatinine ratio(UACR).Another 120healthy subjects were selected as healthy control group.The clinical indexes of the four groups were analyzed and compared.Results The serum Adropin level in the healthy control group,normal albuminuria group,microalbuminuria group,and massive albuminuria group decreased in order,and the CysC level increased in order,and the differences between the groups were statistically significant(P＜0.05).Spearman correlation analysis showed that the level of serum Adropin was negatively correlated with age,duration of DM,systolic blood pressure(SBP),UACR,CysC,and β2-microglobulin(β2-MG);the level of CysC was positively correlated with age,duration of DM,SBP,UACR,and β2-MG;the levels of serum Adropin and CysC were negatively correlated with body mass index.The results of receiver operating characteristic curve analysis showed that serum Adropin and CysC had diagnostic value for DKD(P＜0.05).Conclusion The lower the serum Adropin level and the higher the CysC level in DKD patients,the disease is more serious.In predic-ting DKD,serum Adropin and CysC may become serological indicators for diagnosing DKD,providing more and more powerful evidence for the early diagnosis of DKD.
