Study summary

We aim to determine whether low FODMAP diet in patients with chronic pouchitis will improve symptoms and pouch inflammation.

Read the detailed description

Following recruitment for entry into the study, subjects be asked to complete symptom surveys and provide a fecal sample for calprotectin measurement. Shortly after their screening visit, patients will be randomized 1:1 to either the low FODMAP diet (experimental) or regular diet (control) group. Patients in the experimental group will schedule a telephone visit with a registered dietician. During this approximately hour-long session, patients in the low FODMAP cohort will be counseled regarding FODMAP containing foods. They will be asked to adhere to this diet over the next 6 weeks. At the end of the 6 week period, subjects will complete a 3-day food diary. Those in the regular diet group will be contacted by the dietician and given an educational handout at the beginning of the study period regarding best dietary practices. At the end of the 6 week study period, both groups will again be asked to complete another set of symptom surveys and provide a fecal sample for calprotectin measurement.

Interventions

  • BehavioralLow FODMAP Diet

    Patients in the low FODMAP group will schedule a telephone visit with a registered dietician. During this approximately hour-long session, patients in the low FODMAP cohort will be counselled regarding FODMAP containing foods and how to effectively remove them while maintaining a nutrition-rich diet.

  • BehavioralRegular Diet

    Patients in the regular diet group will receive an educational handout discussing low fiber diet, which is standard of care for those with pouchitis symptoms.

What researchers measure

Primary outcomes

  1. Mean Difference in Fecal Calprotectin

    Time frame: 6 weeks

Secondary outcomes

  1. Mean Difference in Composite Symptom Scores

    Composite symptom score will include both clinical portion of Pouchitis Disease Activity Index as well as Oresland score, with possible scores ranging from 0-21 (higher number indicates higher symptom burden)

    Time frame: 6 weeks

  2. Mean Difference in Cleveland Global Quality of Life Score

    Time frame: 6 weeks

  3. Rate of Normalization of Fecal Calprotectin

    Time frame: 6 weeks
