Mimosa: microbiota against inflammatory bowel disease

24 September 2019
Background
Inflammatory bowel disease (IBD) is a term to describe conditions that are characterized by chronic inflammation of the bowels, such as Crohn’s disease and ulcerative colitis. IBD occurs in about 8 out of each 1000 people and tends to start between 15 – 25 years of age. These conditions cannot yet be cured, and their treatment options and indirect costs are a substantial drain on the healthcare system.
Current treatments include medication, lifestyle changes, and – if no other solution provides relief – surgery. Roughly 10% of Belgium’s healthcare budget goes to IBD treatments. But only 30% of these treatment options proves efficient and many patients relapse. Recent research, however, has shown us a glimpse of the microbiome’s potential in remedying various gut-related conditions. Therefore, MIMOSA will explore microbiome-based strategies (fecal transplants, development of new probiotics and refinement of existing ones, and the repurposing of existing medication) for IBD treatment and relief.

Goals
The project aims to formulate microbiota modulating strategies in inflammatory bowel disease and includes
the set-up of a validation pipeline that starts in the lab and ends in the clinic. This pipeline streamlines the
translational trajectory of the four strategies pursued in parallel:
- fecal transplants
- developing new probiotics
- refining existing probiotics
- repurposing existing medication that may affect microbiome composition

Combining these different strategies increases the potential to achieve fast measurable results with a maximal impact on an important societal health issue.

Séverine Vermeire (UZ Leuven) explains the impact of IBD on patients’ lives: “These conditions have a major impact on the quality of life of the patients. Up to a quarter of people suffering from ulcerative colitis and over half of Crohn’s disease patients will have to undergo surgical removal of significant parts of their bowels.

Partners
The project combines the expertise of Jeroen Raes and Johan Thevelein (VIB-KU Leuven Center for Microbiology), Séverine Vermeire (UZ Leuven), and Peter Bossuyt (Imelda General Hospital Bonheiden).

Societal impact
Through this project, the researchers will spread awareness about the potential of microbiota-mediated
treatment options in treating IBD. The development of alternative treatment strategies for IBD will also decrease the healthcare burden of this group of conditions and the impact on patients’ personal lives.
