All of us have millions of bacteria living in our gut. These bacteria are very important to our health providing us with protection against infections of the gut, allowing us to gain extra nutritional value from food we eat and helping our immune system. Changes in the balance of these many bacteria can make us vulnerable to infections both from within and from outside the gut. Certain bacteria may also be directly associated with some diseases of the gut. Research by doctors and scientists into relationships between the bacteria normally found in our gut and certain diseases of the gut is helping to develop food supplements and other therapies to treat these diseases.

This study involves research into the usefulness and safety of two probiotic products in maintaining remission in Crohn's disease and ulcerative colitis. Approximately 360 patients with Crohn's disease and ulcerative colitis from Ireland, Finland and Spain will be involved in the study. The yoghurts used in this study contain either Lactobacillus salivarius subsp. salivarius or Bifidobacterium infantis.

Further study details as provided by University College Cork:

Primary Outcome Measures:
  • To determine whether ingestion of probiotic preparations (containing Lactobacillus salivarius subsp. salivarius UCC118 or Bifidobacterium infantis 35624) can help in the maintenance of remission of patients with Crohn's disease and ulcerative colitis [ Time Frame: One year ]

Secondary Outcome Measures:

Ages Eligible for Study:   up to 75 Years   (Child, Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria for Crohn's Disease:

  • Patients must be in clinical relapse with a CDAI score >150.
  • Probiotic consumption must start within 2 weeks of commencing steroid use.
  • To achieve remission, administration of steroids to the patients must follow the guidelines: Start dose of 40 mg per day, Taper daily dose by 5 mg per week every 1-2 weeks from 40 mg to 20 mg. Reduce thereafter from 20 mg - 0 mg ensuring the dosage is reduced to 0 mg by end of week 12.
  • Patients must be taking 5-ASA.

Inclusion Criteria for Ulcerative Colitis:

  • Patients must be within one month of entering remission following a documented episode of relapse (despite the use of 5-ASA).
  • Remission is defined as patients who experience <3 bowel movements (without frank/gross blood) per day on >3 days out of 7 and are off all steroids including topical steroids.
  • Patients may be receiving treatment involving 5-ASA or 5-ASP. However, this dose may not vary during the study.

Exclusion Criteria:

  • Age - patients over 75 years will be excluded.
  • Be pregnant, or have the desire to become pregnant during the study period.
  • Patients with clinically significant immunodeficiency (quantitative immunoglobulin levels will be performed before entry to trial).
  • Patients who are considered to be poor clinical attendees or be unlikely for any reason to be able to comply with the trial.
  • Concomitant Drug usage - Patients may not be receiving any treatment with 6-Mercaptopurine, Azothioprine or cyclosporin.
  • Patients may not be receiving treatment involving experimental drugs.
  • Patients who have been on antibiotics within the previous month or who are likely to require antibiotics during the trial period will be excluded.
  • Previous surgery - patients will be excluded if the have undergone resection of more than one (1) metre of bowel in the past. Patients who have undergone less extensive surgical resection of bowel will be eligible provided there is objective (endoscopic or radiological) evidence of recurrence.
  • Malignancy or any concomitant end-stage organ disease.
