INTRODUCTION: A relationship between inflammatory response and coagulation is suggested by many observations. In particular, pro-inflammatory cytokines, such as TNFalpha, promote the activation of coagulation and reduce the production of anticoagulant molecules. It is known that inflammatory bowel diseases show a prothrombotic state and a condition of hypercoagulability. Aim of our study was to evaluate whether anti-TNFalpha therapy induces changes in the levels of coagulation activation markers in IBD patients. MATERIALS AND METHODS: We analyzed 48 plasma samples obtained before and 1 hour after 24 infliximab infusions (5 mg/kg) in 9 IBD patients (5 men and 4 women; mean age: 47.6+17.6 years; 4 Crohn's disease, 4 Ulcerative Colitis,1 Indeterminate Colitis). F1+2 and D-dymer levels were measured in each sample using ELISA methods.The data were statistically analyzed by means of Wilcoxon matched paired test. RESULTS: Median F1+2 levels were markdely reduced 1 hour after anti-TNFα infusion (median pre-infusion levels were 247.0 pmol/L and median post-infusion levels were 185.3 pmol/L) (p |
