Eligibility
Inclusion criteria
Inclusion criteria: • Ulcerative colitis, histologically and endoscopically confirmed • Endoscopically moderate to severe disease with a eMayo score =2 • Start of medical treatment • >18 years of age
Exclusion criteria
Exclusion criteria: A potential subject who meets any of the following criteria will be excluded from participation in this study: • Proctitis only • Colonic stricture at baseline endoscopy • Imminent need of surgery • Sigmoidoscopy/colonoscopy older than eight weeks • Ongoing gastroenteritis • Cytomegalovirus (CMV) associated colitis • Obesity (BMI >35 kg/m²) • A normal bowel wall < 2mm at baseline ultrasonography
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The main endpoint of this study will be change in bowel wall width in millimetres within 0 to 26 weeks against the reference standard of endoscopy where response on endoscopy is defined as a decrease of at least 1 point in eMayo-score at follow-up endoscopy after 8 to 26 weeks. | — |
Secondary
| Measure | Time frame |
|---|---|
| • Change of other ultrasound parameters within 0 to 26 weeks against both eMayo and UCEIS at follow-up endoscopy between week 8 and 26 • Change of all ultrasound parameters within 0 to 26 weeks against clinical response according to clinical disease activity indices (Mayo, SCCAI) • Change of all ultrasound parameters within 0 to 26 weeks against biochemical parameters (blood and faecal parameters) • Ultrasound parameters at baseline, week 1, 2 and 6 predicting response to treatment according to response on follow-up endoscopy between week 8 and 26 (eMayo, UCEIS) • Ultrasound parameters at baseline, week 1, 2 and 6 predicting remission on follow-up endoscopy between week 8 and 26 (eMayo, UCEIS) • Ultrasound parameters at baseline, week 1, 2 and 6 predicting response to treatment according to response based on clinical disease activity indices (Mayo, Lichtiger score) • Ultrasound parameters at baseline, week 1, 2 and 6 predicting remission according to clinical disease activity indices (Mayo, SCCAI, Lichtiger score) • Ultrasound parameters at baseline, week 1, 2 and 6 predicting response to treatment according to response based on biochemical parameters (faecal calprotectin, CRP) • Ultrasound parameters at baseline predicting deterioration in acute severe ulcerative colitis according to Oxford criteria • Ultrasound parameters at baseline, week 1, 2 and 6 predicting colectomy within 0 to 26 weeks. • Ultrasound parameters at baseline, week 1, 2 and 6 predicting failing steroid treatment | — |
