Clinical Profiling of Anti-inflammatory Fibre Supplements in Patients With Ulcerative Colitis: Towards Personalized Complementary Strategies.
The goal of this clinical trial is to determine the clinical effects of two different dietary fibre supplements, acacia gum (AG) and microcrystalline cellulose (MCC), in patients with ulcerative colitis. The main question it aims to answer is: Can the fibre supplements reduce gut inflammation (fecal calprotectin)? Researchers will compare AG and MCC to a placebo (a look-alike substance that contains no fibre) to see if the fibre supplements improve inflammation in ulcerative colitis. Participants will add their assigned fibre supplement or placebo to their usual diet daily for 6 weeks. They will visit the clinic at baseline, week 3, and week 6 to provide samples (stool, blood) and complete various questionnaires.
• Known diagnosis of ulcerative colitis.
• Measured fecal calprotectin of \>250 µg/g at screening.
• Mild disease: Partial Mayo Scoring Index Assessment for UC between 0-4 (adult patients).
• Mild disease: Pediatric UC Activity Index (PUCAI) between 0-34 (pediatric patients).
• Tanner stage 5 for pediatric patients.
• Weight \>50kg.
• No changes to IBD-related medications in three months prior to study onset (stable therapy, including use of 5-aminosalicylic acid, biologics, and immunosuppressive medications; some minor adjustments allowed, such as increasing dose for weight change, or change to a compatible/generic treatment).
• Men and women; the latter must be menstruating and using contraceptives.
