NCT03000101

Brief Summary

The aim of this research is to study the effects of a pomegranate juice on calprotectin levels in patients suffering of inflammatory bowel disease (IBD) in clinical remission. Fecal calprotectin levels, surrogate marker of mucosal inflammation, will be measured from baseline to 12 weeks later (end of intervention). Systemic and mucosal changes of biochemical and molecular inflammatory response markers will be also assessed.

You may qualify if:

  • Patients with Ulcerative Colitis (diagnosed on the base of clinic, endoscopic, and histologic criteria) in clinical remission (SCCAI = 0) from at least three months and in stable therapy (without therapeutic modifications in the three previous months) with mesalazine, immunomodulators and/or biologics.
  • Patients affected by Crohn's Disease, particularly involving sigmoid colon and rectum (diagnosed on the base of clinic, endoscopic, and histologic criteria) in clinical remission (CDAI \< 150) from at least three months and in stable therapy (without therapeutic modifications in the three previous months) with mesalazine A, immunomodulators and/or biologics.
  • Fecal calprotectin at baseline ≥ 100 microg/g.
  • Signed informed consent.

You may not qualify if:

  • Patients affected by Ulcerative Colitis and Crohn's Disease with severe endoscopic disease activity (Ulcerative Colitis: Mayo Endoscopic Score = 3; Crohn's Disease: Simple Endoscopic Score SES-CD \> 15).
  • Patients on steroid therapy in the two previous months.
