Brief Summary:
The Study
1. Prospective trial of the Niv score validating score against known activity indices - see addendum A for Niv score
2. Known Crohn's disease patients undergoing capsule endoscopy are identified - see addendum B for inclusion/exclusion criteria
3. Prior to capsule exam, temperature is taken, height and weight measured, bloods are drawn for albumin, ESR, HCT, CRP
4. Prior to capsule exam, symptom/exam questionnaire is completed - see addendum C for questionnaire
5. Capsule exam is performed
6. CD of de-identified is made at the study site.
7. Landmarks are confirmed and the small bowel transit time is divided into 2 and labeled on thumbnails
8. CDs are copied
9. CDs of study patients are provided to blinded readers
Detailed Description:
The Niv score was devised to measure mucosal disease activity in Crohn's disease using capsule endoscopy. This scoring index is based on inflammatory score parameters: Erythema, hyperemia, edema, denudation, nodularity, apthae, erosion, ulcer, bleeding), extent score: Focal, patchy, diffuse, and stricture score: single-passed, multiple-passed, obstruction. The higher the score, the more involvement is observed. The advantage of this index is that it actually measures disease activity and not symptoms in an easy non-invasive manner. For assessing Crohn's disease, mucosal healing can be directly seen and if there is no mucosal disease there can be no symptoms secondary to inflammatory bowel disease. The subjective nature of disease activity indices is avoided, as is the problem of disease without symptoms. It is envisioned that the Niv score could diagnose Crohn's disease (excluding normally occurring mucosal breaks), identify NSAID damage, measure disease activity / severity, measure drug response for clinical trials and in practice, and guide medical management for the patient's with small bowel Crohn's disease.
This study will measure the Niv score against CDAI. Since capsule endoscopy assesses mucosal disease and not symptoms it is not envisioned that the Niv score will perfectly correlate with the Harvey-Bradshaw score. It is envisioned that the Niv score will have the same direction. Both of these indices will be determined as part of a multicenter trial. The trial design is outlined below.
