CDAI remission
Tidsramme: Week 12
|
Crohn's Disease Activity Index (CDAI) is a research tool used to quantify the symptoms of patients with Crohn's disease. It is based on: number of loose stools, abdominal pain, general well-being, extraintestinal complications, antidiarrheal agents used in the previous 7 days, abdominal mass felt on palpation, hematocrit and body weight |

Endoscopic response
Tidsramme: Week 12
|
Simple Endoscopic Score for Crohn's Disease (SES-CD) is based on the evaluation of five defined bowel segments (rectum, sigmoid + descending colon, transverse colon, ascending colon, and terminal ileum), and in these segments the presence and size of ulcerations and the extent of the inflammatory area and stenosis are assessed |
