Plasma levels of thrombin activatable fibrinolysis inhibitor antigen in active and inactive inflammatory bowel disease.
BACKGROUND
The clinical course of patients with inflammatory bowel disease (IBD) is frequently complicated by thromboembolic events and may involve the arterial and venous systems. Although not uniformly documented, several studies document substantial alterations in markers of coagulation and fibrinolysis in patients with IBD.


METHODS
45 patients with IBD (31 UC,14 CD) were included in the study. Age and sex matched 16 volunteers were used as a control group. TAFI antigen was determined using an ELISA kit VisuLiseTM for quantitative measurement.


RESULTS
Inflammatory parameters such as white blood cell, platelet levels, erythrocyte sedimentation rate, C-reactive protein were found to be significantly higher in active disease group compared to inactive patients. Coagulation parameters of prothrombin time, activated partial thromboplastin time and d-dimer levels showed no significant difference between active and inactive IBD. Fibrinogen levels were significantly higher in clinically active IBD patients. Plasma TAFI levels demonstrated no significant difference between active and control, inactive and control as well as active and inactive groups. We observed no significant changes in levels of β-TG and PF-4 between active and inactive disease group.


CONCLUSIONS
We studied plasma TAFI levels in IBD. In conclusion, plasma TAFI levels does not appear to represent to be a marker of activation in IBD in contrast to literature. So further studies covering more patients with different clinic and disease activity status might improve the perspective on this issue.
