Prevalence and risk factors of chronic kidney diseases in hospitalized patients with type 2 diabetes mellitus

Abstract

Through retrospective analysis of the clinical and laboratory data of 1 466 inpatients with type 2 diabetes mellitus(T2DM),we investigated the prevalence of chronic kidney disease (CKD) and analyzed the risk factors.The prevalence of CKD in hospitalized patients with T2DM was 52.25％.In the patients with CKD,protein urine was present in 93.47％ of the cases,27.93％ of them had glomerular filtration rate(eGFR) ≤60 ml · min-1 · 1.73 m-2,damage of renal tubular function was present in 24.28％,and abnormal renal imaging in 14.88％.Logistic regression showed that age,body mass index(BMI),duration of diabetes,systolic blood pressure,serum uric acid,low density lipoprotein-cholesterol (LDL-C),and smoking were independently associated with patients of T2 DM and CKD.The prevalence of CKD was increased with aging,diabetic course,BMI,and LDL-C.CKD is a common chronic complication in patients with T2DM,especially in patients with prolonged course,advanced age,and obesity.Much attention should be paid to early detection of CKD in patients with diabetes.In addition to detecting urinary protein and eGFR,renal tubular function and morphological examination should also be included.
