The correlation between Plasma Fibrinogen Levels and Glycemic Status in type 2 Diabetes Mellitus

Abstract Introduction/Objective Background: Fibrinogen is considered a well-known contributor to the progression of atherosclerotic lesions and a predictor of cardiovascular events. Patients with diabetes mellitus (DM) have higher levels of fibrinogen, which may raise their thromboembolic risk for cardiovascular disease (CVD). Plasma fibrinogen is an indicator of inflammation, and endothelial dysfunction has been described as an independent risk factor for cardiovascular morbidity in type-2 diabetes mellitus (T2DM) patients. Poor glycemic control has been reported to be associated with hyperfibrinogenemia. Aim This study aims to estimate the levels of fibrinogen in patients with type-2 diabetes mellitus and determine its correlation with glycated hemoglobin levels. Methods/Case Report Subjects and methods: It is a cross-sectional analytic study conducted in the Benghazi Diabetic Clinic, Libya. Patients who were diagnosed with type 2 diabetes mellitus, either newly detected or already on diet or treatments, were included in the study during the period between May 2022 to December 2022. A total of 231 adult subjects were selected, with ages ranging from 20-80 years. Random blood sugar levels were assessed. Plasma fibrinogen levels (mg/dl) were estimated by the "Clauss method" and glycosylated hemoglobin (%) by the "immunoturbidimetric method." Patients were categorized into three groups depending upon the HbA1c values, i.e., into <5.7% (good control), 5.7-6.5% (fair control), and >6.5% (poor control). Results (if a Case Study enter NA) Result: Out of 231 subjects, (40.6%) were males and (59.4%) were females, with a mean±SD of age was (47.03±15.54) years. There was a significant positive correlation between fibrinogen and HbA1c in the fair control group (r=0.424, p=0.003) and the poor control group (r=0.369, P=0.000). Moreover, the difference between fibrinogen and age in the good control group was significant (p>0.05), whereas no significance was recognized in other groups. Conclusions Plasma fibrinogen levels are elevated in type 2 DM, and this elevation was associated with poor glycemic control; increased HbA1c levels. The other parameters which correlated with plasma fibrinogen levels were age. Lowering plasma fibrinogen levels could be an integral approach to cardiovascular complications reduction in type-2 DM.
