RESUMO
Objective:To investigate the relationship of plasma cholinesterase (ChE) with triglyceride (TG) levels in newly diagnosed patients with type 2 diabetes (T2DM).Methods:Clinical data and biochemical parameters of 321 patients with newly diagnosed T2DM admitted to the Department of Endocrinology of People′s Hospital of Shanghai Putuo from January 2018 to June 2020 were retrospectively collected. The patients were classified into four groups based on the plasma ChE level: Q1group ( n=81, <6 915 U/L), Q2 group ( n=80, 6 916-8 268 U/L), Q3 group ( n=80, 8 269-9 578 U/L), and Q4 group ( n=80, ≥9 579 U/L). The correlation of plasma ChE with TG level was analyzed. Results:With the increased ChE level, TG level significantly increased ( P<0.001). Correlation analysis showed that ChE was positively correlated with body weight, body mass index (BMI), TG, total cholesterol (TC), low density lipoprotein cholesterol (LDL-C), uric acid (UA), alanine aminotransferase (ALT), aspartate aminotransferase (AST)( r=0.35, 0.39, 0.35, 0.31, 0.27, 0.24, 0.25, 0.11, P<0.05, P<0.01 or P<0.001)while negatively correlated with age, systolic blood pressure, blood urea nitrogen (BUN), creatinine, and glycated albumin (GA)( r=-0.46、-0.14、-0.20、-0.14、-0.21, P<0.05 or P<0.001). Multivariate stepwise regression analysis showed that ChE was an independent risk factor for TG ( β=0.270, P<0.001). Logistic Multivariate regression analysis showed that after adjustment for sex, age, body weight, hemoglobin, leukocytes, total protein, albumin, globulin, ALT, BUN, creatinine, uric acid, smoking history, drinking history, HbA 1C, GA, TC, and LDL-C, the risk of hypertriglyceridemia in Q4 was 6.024 folds higher than Q1 group ( P=0.011). With the TG (1.70 mmol/L) as cut-off value, the optimal cut-off point of the ChE was 7 801 U/L, as calculated by receiver operating characteristic(ROC) curve analysis of ChE and hypertriglyceridemia. Conclusions:ChE level is positively correlated with TG in newly diagnosed patients with T2DM.
RESUMO
Objective:To investigate the relationship between normal plasma fibrinogen(FIB)levels and disease duration in elderly patients with type 2 diabetes mellitus(T2DM).Methods:Clinical data and biochemical test results of 1 116 elderly subjects with T2DM admitted to the Department of Endocrinology of Shanghai Tianyou Hospital from January 2016 to October 2019 were retrospectively collected and analyzed.Subjects were classified into four groups based on the duration of DM: the Q1 group(n=276, < 2.0 years), the Q2 group(n=278, 2.0-7.9 years), the Q3 group(n=280, 8.0-13.9 years)and the Q4 group(n=282, ≥ 14.0 years). The correlation between FIB and the duration of DM was analyzed.Results:With the prolongation of DM duration, FIB levels increased significantly( P<0.05). Pearson correlation analysis showed that the duration of DM was positively correlated with FIB, age and serum creatinine( P<0.01). Multiple stepwise regression analysis showed that the duration of DM was an independent factor for FIB( β=0.104, P<0.01). Logistic multiple regression analysis showed that after adjusting for sex, age, body mass index, systolic pressure, diastolic pressure, total cholesterol, triglycerides, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, serum creatinine, alanine aminotransferase, fasting plasma glucose, glycosylated hemoglobin, smoking and drinking, the risk of hyperfibrinogenemia was 2.436 and 2.104 times higher, respectively, in Group Q4 and Group Q3 than in Group Q1(95% CI: 1.317-4.507, P<0.01; 95% CI: 1.144-3.871, P<0.05). With the third-quartile FIB(3.70 g/L)as the cut-off value, the optimal cut-off point of the DM course was 9.5 years as calculated by receiver operating characteristic(ROC)curve analysis of DM duration and hyperfibrinogenemia. Conclusions:The FIB level is positively correlated with DM duration in elderly patients with T2DM.
RESUMO
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.
