Abstract:
Objective:To analyze the relationship between plasma fibrinogen(FIB) within normal range and microalbuminuria in elderly patients with type 2 diabetes mellitus.Methods:A total of 869 elderly subjects with type 2 diabetes mellitus admitted to the Department of Endocrinology of Shanghai Fifth People′s Hospital from October 2012 to October 2014 were included in the study. The patients were divided into four groups based on the quartile level of FIB: Q1 group(<2.42 g/L), Q2 group(2.42-2.89 g/L), Q3 group(2.90-3.61 g/L), and Q4 group(≥3.62 g/L). The relationship between FIB and urinary albumin/creatinine ratio(UACR) was analyzed.Results:With the increasing of FIB, the level of UACR was significantly elevated( P<0.05). Pearson correlation analysis showed that FIB was positively associated with age, duration of diabetes, creatinine(Cr) and UACR in men and women( P<0.01). Multiple regression analysis showed that FIB was an independent factor of UACR( P<0.01). Logistic regression analysis showed that the risks of microalbuminuria and macroalbuminuria were respectively 4.536 folds(95% CI 2.516-8.175, P<0.01) and 13.314 folds(95% CI 2.925-60.612, P<0.01) in Q4 group, and 2.177 folds(95% CI 1.273-3.724, P<0.01) and 4.098 folds(95% CI 1.101-19.226, P<0.05) in Q3 group as compared with Q1 group after adjused by following factors: gender, age, duration of diabetes, body mass index(BMI), systolic blood pressure(SBP), diastolic blood pressure(DBP), fasting plasma glucose(FPG), HbA 1C, total cholesterol(TC), triglyceride(TG), low density lipoprotein-cholesterol(LDL-C), Cr, alanine aminotransferase(ALT), as well as smoking and drinking behavior. Based on the cut off values to UACR 30 mg/g and 300 mg/g, the receiver operating characteristic curve(ROC) was used to evaluate the value of FIB for UACR. The optimal cut-off value of FIB was 3.18 g/L and 3.22 g/L respectively. Conclusions:Plasma FIB was closely associated with microalbuminuria in elderly patients with type 2 diabetes mellitus, which may be considered as one of the predictors for diabetic nephropathy.
