AIM: To investigate the levels of D-dimer(DD) and vonWillebrand factor(vWF) and the relationship between DDand vWF in ulcerative colitis(UC) patients.METHODS: A total of 29 plasma specimens were obtainedfrom patients with ulcerative colitis (male 13, female 16),aged 21-47 years (33 + 11). Disease activity was assessed byTruelove-Writeria. Patients with a score of above 5 wereregarded as having active colitis. Twenty healthy people(male 12, female 8),aged 19-53 years(31 + 14), ssrved asnormal controls. Blood samples were taken from anantecubital vein puncture. Blood(1.8 mL) was injected intothe tubes containing sodium citrate (0. 13 mmol/L). Theplasma was obtained by centrifugation at 3000 r@ min-1 for 10min, and stored at -80 ℃ until assayed by ELISA.RESULTS: The mean plasma levels of DD and vWF in activeUC patients were significantly higher than those of thecontrols(0.69+0.41 vs0.27+0.11, P＜0.01;143+46 vs103 + 35, P ＜ 0.01 ). The mean plasma levels of DD in thepatients with active disease were higher than those withinactive disease(0. 69 + 0. 41 vs 0.48+0.29, P＜0.05). Thelevls of v WF were not different between active and inactivepatients. DD levels were positively related to vWF levels( r =0.574, P ＜ 0. 01 ). There was no significant differencebetween levels of DD and vWF and the scope of disease cndsex of the patients.CONCLUSION: vWF is an important feature and a goodmarker of UC; intravascular thrombus and endothelial celldysfunction were found in UC patients; and the combinedtest of DD and vWF is helpful to distinguish the activity ofthe UC patients.

METHODS: A total of 29 plasma specimens were obtained from patients with ulcerative colitis (male 13, female 16) aged 21-47 years (33+/-11). Disease activity was assessed by Truelove-Writeria. Patients with a score of above 5 were regarded as having active colitis. Twenty healthy people(male 12, female 8) aged 19-53 years(31+/-14) served as normal controls. Blood samples were taken from an antecubital vein puncture. Blood(1.8 mL) was injected into the tubes containing sodium citrate (0.13 mmol/L). The plasma was obtained by centrifugation at 3000 r.min(-1) for 10 min, and stored at -80 degrees until assayed by ELISA. RESULTS: The mean plasma levels of DD and vWF in active UC patients were significantly higher than those of the controls (0.69+/-0.41 vs 0.27+/-0.11, P<0.01 143+/-46 vs 103+/-35, P<0.01). The mean plasma levels of DD in the patients with active disease were higher than those with inactive disease(0.69+/-0.41 vs 0.48+/-0.29 P<0.05). The levels of vWF were not different between active and inactive patients. DD levels were positively related to vWF levels( r =0.574, P<0.01). There was no significant difference between levels of DD and vWF and the scope of disease and sex of the patients. CONCLUSION: vWF is an important feature and a good marker of UC intravascular thrombus and endothelial cell dysfunction were found in UC patients and the combined test of DD and vWF is helpful to distinguish the activity of the UC patients.
