NCT04121806

Brief Summary

The purpose of this study is to determine if a sustainable non-elemental diet can be used as a probiotic tool to alter the dysbiotic microbiome found in individuals with ulcerative colitis and thereby decrease disease activity.

Outcome Measures

Primary Outcomes (2)

  • Change in microbiome composition

    measured by 16S rDNA sequencing and comparing pretreatment diet and the treatment diet within an individual

    10 weeks

  • Change in microbiome function

    measured by shotgun sequencing and comparing difference in enriched functional pathways between pretreatment diet and the treatment diet within an individual

    10 weeks

Secondary Outcomes (2)

  • Decrease in endoscopic disease activity

    10 weeks

  • Decrease in clinical disease activity

    10 weeks

Study Arms (1)

Ulcerative colitis patients with mild to moderate activity

EXPERIMENTAL

Participants will be followed for 14 days on their traditional diet followed by an 8 week intervention with the specially designed and provided treatment diet.

Other: UC intervention diet

Interventions

The treatment diet has been designed based on the literature with the goal of influencing the biodiversity and density of the microbiome. All food through the duration of the 8 week dietary intervention period of the study will be provided to the treatment arm study participants.
