NCT04922476

Brief Summary

The aim of this study is to evaluate the effect of supplementation with Bifidobacterium longum 35624® Alflorex® on frequency and severity of symptoms of abdominal pain using an adapted Irritable Bowel Symptom Severity Scoring System (IBS-SSS) to accurately reflect the pediatric population using the aid of the validated Numeric Pain Rating Scale (NRS-II) in children with Functional Gastrointestinal Disorders (FGIDs).

Outcome Measures

Primary Outcomes (2)

  • Change in IBS symptom severity assessed by an adapted Irritable Bowel Symptom Severity Scoring System (IBS-SSS)

    The IBS-SSS measures symptom severity in IBS patients and is a reliable and validated questionnaire taking into account the composite score of abdominal pain, number of days with abdominal pain, bloating/distention, satisfaction with bowel habits and IBS-related quality of life. For this study, an adapted version was used in conjunction with the NRS-11 pain scale for the purposes of accurately capturing the response of a pediatric population. The NRS-11 pain scale goes from 0-10 with 0 indicating "no pain" and 10 indicating "very severe pain."

    Change from baseline, assessed at 6 and 12 weeks of supplement intake

  • Change in abdominal pain assessed by the Numeric Rating Scale for pain

    The Numeric Rating Scale (NRS-11) is an 11-point scale for patient self-reporting of pain which goes from 0 (no pain) to 10 (worst pain)

    Change from baseline, assessed at 6 and 12 weeks of supplement intake

Secondary Outcomes (4)

  • Change in quality of life assessed by the Irritable Bowel Syndrome-Quality of Life questionnaire

    Change from baseline, assessed at 6 and 12 weeks of supplement intake

  • Change in stool consistency assessed using the Bristol Stool Form Scale

    Change from baseline, assessed at 6 and 12 weeks of supplement intake

  • Change in stool frequency

    Change from baseline, assessed at 6 and 12 weeks of supplement intake

  • Change in days absent from school

    Change from baseline, assessed at 6 and 12 weeks of supplement intake
