Risk factors for diabetic kidney diseases in inpatients with type 2 diabetes

Objective To analyze risk factors for diabetic kidney disease(DKD)in inpatients with type 2 diabetes. Methods A total of 930 inpatients with type 2 diabetes were enrolled in the study and grouped according to different levels of estimated glomerular filtration rate(eGFR), albuminuria, and diabetic retinopathy. Logistic regression analysis was adopted to explore the risk factors for DKD in inpatients with type 2 diabetes. Results (1)The prevalence of albuminuria in patients with type 2 diabetes mellitus was increased with declining eGFR(P<0.05). (2)The prevalences of DKD and non-diabetic renal disease(NDRD)in patients with type 2 diabetes mellitus were 22.26% and 8.92%, respectively. Compared with patients with NDRD, patients with DKD had longer diabetic duration, higher levels of systolic blood pressure, serum creatinine, and urinary albumin excretion, and lower levels of hemoglobin[(125.40±21.95 vs 138.18±19.67)g/L], serum albumin[(37.45±5.54 vs 40.55±3.55)g/L], and eGFR[(89.66(59.10-108.25)vs 103.15(85.39-114.88)ml·min-1·(1.73 m2)-1, all P<0.05]. (3)Logistic regression analysis showed that age, diabetic duration, systolic blood pressure, serum uric acid, diabetic retinopathy, and hypertension are the independent risk factors for diabetic kidney disease in inpatients with type 2 diabetes, while serum albumin was the protective factor(all P<0.01). Conclusions A variety of clinic risk factors were associated with DKD. Better control of blood pressure, serum uric acid, and hypoalbuminemia should be performed to delay the progress of DKD.
