Combined Nutritional Therapies for the Treatment of Ulcerative Colitis

Summary

Ulcerative colitis (UC) is an entity of complex etiology where environmental, genetic and intestinal microflora-related factors trigger and perpetuate a chronic inflammation of the gastrointestinal tract. It is suspected that an alteration in primary intestinal microbial colonization (dysbiosis) could trigger, or at least contribute to, said oversized immune response. The hypothesis is that the administration of a series of fibers, could improve the bacterial diversity and repair the dysbiosis that has been seen in patients affected by ulcerative colitis, improving the clinical evolution of it. The primary objective of the present study is to know the impact on the microbiota of patients with UC in remission derived from the administration of dietary fibers. The RETOS study is a pilot project in which a population of patients with UC is tested for the effect on the composition of the microbiota that would have the administration of various combinations of fibers, in addition to the tolerability and acceptance by the patient. The clinical applicability derived from this intervention would be to improve the diversity of intestinal flora of patients with ulcerative colitis.
