The aim of this study is to test Eicosapentaenoic acid's effects on markers relevant to colorectal carcinogenesis, RNA and DNA profiles, and the possibility that Eicosapentaenoic Acid treatment might be associated with changes of the gut microbiota and metabolomic profiles in patients with long-standing ulcerative colitis.

  • Changes of membrane fatty acid composition from baseline [ Time Frame: baseline and 3 months ]
  • Changes of metabolomic profiles from baseline [ Time Frame: baseline and 3 months ]

Enrollment: 25
Study Start Date: January 2014
Primary Completion Date: August 2015 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Eicosapentaenoic Acid
Subjects with long-standing ulcerative colitis and meeting the inclusion criteria will receive 2 g/day of Eicosapentaenoic Acid as a supplement for 90 days
Dietary Supplement: Eicosapentaenoic Acid
Twenty patients with long-standing ulcerative colitis undergoing the usual colonoscopic surveillance + biopsy sampling will be recruited. At entry six extra biopsy samples will be collected from the colon. We will also collect blood (for serum, plasma and red cells isolation), urine and stools. Subjects will then receive 2 g/day of Eicosapentaenoic Acid (ALFA ™, SLA Pharma AG, Switzerland) as a supplement for 90 days. At the end of the study each subject will undergo sigmoidoscopy for the collection of 6 biopsies. Blood, urine and stools will be obtained prior to the procedure.
Other Name: ALFA ™
No Intervention: Normal controls
Five patients undergoing screening colonoscopy and polypectomy using biopsy forceps. Six biopsies of healthy mucosa will be collected at the time of colonoscopy. Faeces, urine and blood samples will be collected prior to performing colonoscopy. The samples will serve as healthy reference for the basic studies.


Ages Eligible for Study:   18 Years to 70 Years   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Arm: experimental

Inclusion Criteria:

  • Patients with ulcerative colitis (diagnosed based on clinical criteria, endoscopic and histological) lasting over 8 years, with no clinical activity (SCCAI = 0), and in stable treatment (without any change in treatment in the previous 3 months) with mesalamine, immunomodulators and / or biologics.
  • Baseline fecal calprotectin> 150 micrograms / g.
  • Signed informed consent.

Exclusion Criteria:

  • Patients receiving systemic steroids in the two months prior to study entry.
  • Patients taking concomitant warfarin or other blood thinners.
  • Known or suspected hypersensitivity to eicosapentaenoic acid/omega 3.
  • Women who are pregnant or of childbearing age who do not accept the use of contraceptive methods specified in the study (oral contraception, IUDs) and breastfeeding women.
  • Patients with severe medical conditions that, in the opinion of the investigator, contraindicate the patient's participation in the study.
  • Changes of treatments and / or use of experimental drugs within 3 months before inclusion in the study.
  • Use of Probiotics
