Insights
Deep vein thrombosis (DVT) is closely linked to inflammation and coagulation. Elevated levels of C-reactive protein (CRP), fibrinogen (Fg), and coagulation factors VIII (FVIII:C) and IX (FIX:C) are significant risk factors for DVT.
Area of Science:
- Biochemistry
- Hematology
- Immunology
Context:
- Deep vein thrombosis (DVT) is a significant health concern.
- The interplay between inflammation and coagulation in DVT pathogenesis requires further elucidation.
Purpose:
- To investigate the correlation between deep vein thrombosis (DVT) and key inflammatory and coagulation markers.
- To explore the role of inflammation and coagulation interactions in the mechanism of DVT.
Summary:
- This study compared plasma levels of C-reactive protein (CRP), fibrinogen (Fg), coagulation factor VIII (FVIII:C), and coagulation factor IX (FIX:C) in 59 DVT patients and 26 controls.
- Significantly higher levels of CRP, Fg, FVIII:C, and FIX:C were observed in the DVT group (p < 0.01).
- Plasma CRP levels strongly correlated with Fg, FVIII:C, and FIX:C (p < 0.01), suggesting a link between inflammation and coagulation.
Impact:
- Elevated plasma CRP may serve as a predictor for DVT.
- Increased plasma levels of Fg, FVIII:C, and FIX:C are identified as crucial risk factors for DVT.
- The interaction between inflammation and coagulation pathways is implicated as a significant factor in DVT development.
Abstract:
This study was purposed to investigate the correlation of deep vein thrombosis (DVT) with C-reactive protein (CRP), fibrinogen (Fg), coagulation factor VIII (FVIII:C), coagulation factor IX (FIX:C) and to explore the effect of inflammation and coagulation as well as their interaction in DVT and its mechanism. 59 patients with DVT undergoing selective venous ultrasonography and 26 healthy individuals as controls were enrolled in this study. The plasma level of CRP was detected by immunoturbidimetry, FVIII:C, FIX:C levels were determined by a one-stage assay and fibrinogen level was measured by full-automatic biochemical apparatus. The results showed that the mean levels of plasma CRP, Fg, FVIII:C and FIX:C were significantly higher in deep vein thrombosis group than that in controls [CRP (2.67 +/- 0.91) vs (0.14 +/- 0.08) mg/dl; Fg (4.73 +/- 1.36) vs (2.79 +/- 0.66)g/L; FVIII:C (126.71 +/- 28.10) vs (81.35 +/- 20.77)%; FIX:C (81.01 +/- 23.60) vs (70.71 +/- 11.3)%] (p < 0.01), and the level of plasma CRP was strongly correlated with Fg, FVIII:C and FIX:C (r(s) = 0.432, 0.571 and 0.544, p < 0.01). It is concluded that the DVT and inflammation are closely related, increased level of plasma CRP may be a predictor of DVT. Increased plasma levels of Fg, FVIII:C and FIX:C all are important risk factors to DVT. Interaction between inflammation and coagulation promote the incidence of DVT, which may be one of DVT pathogenesis.

Extrinsic and Intrinsic Pathways of Hemostasis
The Extrinsic Pathway
The extrinsic pathway of coagulation is typically initiated by tissue damage that exposes blood to tissue factor (TF), a protein released by the damaged tissue cells outside the blood vessels—this interaction with TF triggers biochemical reactions involving specific clotting factors. The key player here is Factor VII, which forms a...
