Relationship between Serum Sialic Acid and Hemostatic Markers in Patients with Type 2 Diabetes Mellitus by Nengneng Zheng, Xinping Shi, Xiongwei Chen, Ying Zheng

Background: Serum sialic acid (SA) is an acute phase response marker. Additionally, it is an independent risk factor for atherosclerotic disease and is higher in patients with type 2 diabetes mellitus (T2DM). The objective of this study was to determine the association of SA with blood coagulation and fibrinolysis in T2DM patients.
Methods: The levels of serum SA and blood coagulation and fibrinolysis markers were measured in patients with T2DM. The associations of SA with hemostatic markers and other variables were assessed.
Results: There were significant correlations between SA and fibrinogen, D-dimer, factor (F) IX, and platelet (PLT) that were independent of smoking, body mass index (BMI), waist-to-hip ratio, hemoglobin A1c (HbA1c), fasting plasma glucose (FPG), triglycerides (TG), total cholesterol (TC) to high-density lipoprotein cholesterol (HDL-C) ratio, and antithrombotic therapy history. Based on logistic regression analyses, the highest tertile groups of fibrinogen, D-dimer, F VIII, F IX, and PLT showed a significantly increased risk of high SA compared with the lowest tertiles after adjusting for age, gender, and antithrombotic therapy history. SA also significantly correlated with duration of diabetes, BMI, FPG, TG, low-density lipoprotein cholesterol (LDL-c), TC-to-HDL-C ratio, and albumin-to-creatinine ratio (ACR).
Conclusions: Elevated serum SA levels are associated with increased coagulability and higher risk of thrombus formation in T2DM patients.
