NCT04566679

Brief Summary

We will perform a randomized, double-blind, placebo-controlled trial to establish whether calcium butyrate relieves symptoms in children with irritable bowel syndrome (IBS). The direct effects of butyrate on inflammation and GI symptoms will be studied in children with IBS. The design used to study the effects of calcium butyrate will be a double blind randomized placebo-controlled parallel design.

Outcome Measures

Primary Outcomes (2)

  • butyrate on GI symptoms

    To assess the severity of pain, a combination of the self-reported visual analog scale (VAS) and the Faces Pain Scale (FPS) will be used. The 0- to 10-mm VAS scale (0, no pain; 10, worst possible pain) include a horizontal color gradient (green to red) plus a rating.

    daily for 14 weeks

  • butyrate on GI symptoms

    Gastrointestinal Symptom Rating Scale (GSRS)

    every two weeks for 14 weeks

Secondary Outcomes (1)

  • butyrate on inflammation

    14 weeks
