Analysis of relative risk factors for diabetic nephropathy / 心血管康复医学杂志

ABSTRACT

Objective: To study relative risk factors for diabetic nephropathy (DN). Methods: A total of 238 patients diagnosed as type 2 diabetes mellitus (DM) were enrolled in the study. According to urine microalbuminuria to urine creatinine ratio (UACR), patients were divided into pure DM group (group DM1, n=90), early diabetic nephropathy group (group DM2 , n=73) and clinical diabetic nephropathy group (group DM3 ,n=75). Clinic data of all patients were collected; Fasting blood glucose (FBG), 2h postprandial blood glucose (2hPB), blood lipids, uric acid (UA), fibrinogen (Fg) and glycosylated haemoglobin (HbA1c) were measured in all patients, and their correlations with DN were analyzed. Results: Compared with group DM1, the course of disease in DM [(7.25±6.29) years vs. (10.25±7.67) years vs. (13.53±7.82) years], levels of FBG [(8.46±2.52) mmol/L vs. (9.52±3.38) mmol/L vs. (10.82±3.30) mmol/L], 2hPB [(18.40±5.64) mmol/L vs. (20.27±5.94) mmol/L vs. (22.59±6.14) mmol/L], HbA1c [(7.96±1.65) % vs. (8.60±1.76) % vs. (9.55±2.09) %], triglyceride [TG, (1.72±0.86) mmol/L vs. (2.34±1.87) mmol/L vs. (3.16±1.85) mmol/L], Fg [(3.49±0.93) g/L vs. (3.88±1.21) g/L vs. (4.99±2.10) g/L] and UA [(295.42±52.34) μmol/L vs. (324.18±96.29) μmol/L vs. (351.23±56.88) μmol/L] significantly increased in group DM2 and group DM3 in order (P<0.01~0.001). Logistic gradual regression analysis indicated that course of DM, HbA1c, TG, Fg and UA were risk factors for DN (OR=1.008~1.910, P<0.01~0.001). Conclusion: The course of DM, blood glucose, blood lipid, uric acid and fibrinogen are risk factors of diabetic nephropathy; increased UACR reflects progress of patient’ condition in DM patients, its detection is used for diabetic prognosis and treatment.
