Abdominal Pain Dietary Supplement: L. reuteri protectis Dietary Supplement: Placebo tablet Phase 4

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Crossover Assignment

Further study details as provided by BioGaia AB:

Primary Outcome Measures:
  • Primary endpoint [ Time Frame: 4 weeks ]
    Pain frequency measured by a subject diary, in the L. reuteri Protectis group and the placebo group, expressed as area under the pain-frequency curve and comparing L. reuteri Protectis vs. placebo over the 4-week supplementation period.

Secondary Outcome Measures:
  • Secondary endpoint [ Time Frame: 56 days ]
    Pain frequency measured by subject diary and expressed as area under the curve, comparing L. reuteri protectis vs. placebo over the initial 2 weeks of the supplementation period. Pain severity measured by the face score system by Wong-Baker at day 14, 28 and 56 (follow up) vs baseline, and area under the curve for weeks 1-4 and 1-2. Treatment success, defined as ≥ 50% reduction in pain frequency in weeks 1-4. Reduction in days of absence from school. Parents' absence from work. Need of rescue medication.

Enrollment: 9
Study Start Date: December 2011
Study Completion Date: April 2013
Primary Completion Date: April 2013 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: L. reuteri protectis tablets
one tablet a day for 4 weeks
Dietary Supplement: L. reuteri protectis
1 tablet once daily for 4 weeks
Placebo Comparator: Placebo tablet
one tablet a day for 4 weeks
Dietary Supplement: Placebo tablet
1 tablet once daily for 4 weeks
Other Name: Placebo

Detailed Description:
Subject will be asked to consume a tablet every day for 4 weeks. Supplementation will be stopped after 4 weeks, and the subjects will be followed up for an additional 4 weeks. The subjects will complete a diary to record frequency and intensity of pain, use of medication, deviation from the usual diet, physical activities, and absence from school and other activities. Gastrointestinal symptoms are assessed.
