Non-nutritive Sweeteners in Inflammatory Bowel Disease
The Effect of Non-Nutritive Food Sweeteners in Inflammatory Bowel Disease
This study will focus on the commonly used non-nutritive sweetener (NNS) sucralose (2 sachets/day resulting in daily dose: sucralose 2.5mg/kg) and its role in changing the gut microbiota in humans with IBD, compared to healthy non-IBD individuals. The investigators will focus on studying IBD patients affected with CD as a proof of principle that could be tested later in other IBD subtype (ulcerative colitis or others specific surgical conditions).

Detaljert beskrivelse
Participation in this study will last for a minimum of 35 days (Phase I: 14-days; baseline with removal of all NNS (eg saccharin, sucralose, steviosides, aspartame, acesulfame-k, erythritol) from the diet, Phase II: 21-days; sucralose intervention, and will involve one virtual visit (study visit 1) and two in-person study visits (study visit 2 and study visit 3).
Fecal & urine samples will be collected before/after each phase. Blood will also be collected.

Quantify the change in Crohn's Disease Activity Index. The Crohn's Disease Activity Index (CDAI) is a validated clinical instrument used to quantify Crohn's disease activity. It evaluates 8 components over a 7-day period: number of liquid or very soft stools, severity of abdominal pain, general well-being, extraintestinal complications, use of antidiarrheal medications, presence of an abdominal mass, hematocrit levels, and body weight deviation. Each component is multiplied by a specific weighting factor and summed to calculate a total score. Total scores range from 0 to approximately 600 points, where lower scores indicate lower disease activity. A score of <150 indicates clinical remission, while a score of >450 indicates severe disease. A negative change from baseline indicates clinical improvement. |
