Summary
Patients with ulcerative colitis (UC) show increased thrombin generation, indicated by thrombin-antithrombin III complexes (TAT), regardless of disease activity. These coagulation changes may influence UC
Area of Science:
- Gastroenterology and Hematology
- Inflammatory Bowel Disease Research
- Coagulation and Thrombosis Studies
Background:
- Ulcerative colitis (UC) can disrupt hemostasis due to altered coagulation factor synthesis and consumption.
- Inflammatory processes in the large bowel contribute to hemostatic imbalances in UC patients.
Purpose of the Study:
- To investigate coagulation system activation in patients diagnosed with ulcerative colitis (UC).
- To assess hemostatic parameter differences between active and inactive UC phases.
Main Methods:
- Studied 42 UC patients (21 active, 21 inactive) and 26 healthy controls.
- Measured thrombin-antithrombin III complexes (TAT), antithrombin III, prekallikrein, von Willebrand factor (vWf), fibrinogen, activated partial thromboplastin time (aPTT), prothrombin, and platelet count.
Main Results:
- UC patients exhibited higher TAT, fibrinogen, and platelet counts, with lower prekallikrein activity and shorter aPTT compared to controls.
- No significant differences in hemostatic parameters were observed between active and inactive UC phases.
- Limited rectal inflammation correlated with lower platelet counts and fibrinogen concentrations.
Conclusions:
- Increased in vivo thrombin generation (higher TAT) occurs in UC patients irrespective of disease activity or extension.
- Coagulation system disturbances in UC may impact the inflammatory bowel process and elevate thrombotic complication risk.
