Resumo

Background: As Crohn's disease (CD) is associated with a high risk of thromboembolic events (TE), including patients with subclinical inflammation, we aim to evaluate the correlation between the impact of endoscopic activity (EA) in the coagulation profiling of CD patients while in clinical remission. Methods: From 164 consecutive CD patients included in clinical remission {[}Crohn's disease activity index (CDAI) < 150], 75 were in the EA group {[}Simplified Endoscopic Score for CD (SES-CD) > 7], 89 were in the endoscopic remission (ER) group (SES-CD <= 2), and 50 were included as healthy controls in the study. Blood samples were analyzed for tissue factor (TF), factor VIII (FVIII), thrombomodulin (TM), ADAMTS-13, von Willebrand factor (VWF), and endogenous thrombin potential (ETP), as well as collecting data regarding risk factors for TE and CD profile. Results: Mean plasma TF activity showed significantly higher levels in the EA group when compared with the ER and control groups (127 pMversus103 pMversus84 pM;p = 0.001), although the VWF:Ag (160%versus168%versus110%;p = 0.001), VWF/ADAMTS-13 (191versus219versus138;p = 0.003), FVIII (150%versus144%versus90%;p = 0.001) and TM (5.13 ng/mlversus4.91 ng/mLversus3.81 ng/ml;p < 0.001) were only increased in CD regardless of EA status when compared with controls. Lastly, ETP with and without TM remained the same in all three groups. Conclusions: CD patients in clinical remission with EA present endothelial lesion inducing TF exposure and subsequent coagulation cascade activation. Recommended thromboprophylaxis for EA outpatient subgroups will require additional investigation in order to be validated. (AU)
