Study of the Role of Pomegranate Juice Ellagitannins in the Modulation of Inflammation in Inflammatory Bowel Disease

The main purpose of the intervention trial is to assess the possible effect of pomegranate juice consumption on reducing fecal calprotectin (FC) levels in volunteers suffering from IBD with a high risk of clinical relapse. In detail, the objectives of this intervention are as follows: (i) assessing the changes in FC levels in the two groups (active treatment, control) from baseline to 12 weeks later (primary outcome); (ii) investigating the systemic and mucosal modifications of selected biochemical and molecular inflammatory response markers in the two groups after 12 weeks of the intervention compared with baseline (secondary outcomes); (iii) evaluating circulating and urinary ellagitannin-derived metabolites from regular pomegranate juice consumption in the two groups before and after the intervention. The detailed study protocol is published in the Trials journal.
