Detailed Description:
Determine the safety and efficacy of different doses of VSL#3 in the treatment of children with irritable bowel syndrome: Children will be recruited from the pediatric gastroenterology clinic at The Children's Medical Center in Dayton, Ohio. Eighty four children will be enrolled in this controlled, double-blinded, randomized study. All children will have had a prior evaluation by a pediatric gastroenterologist who has diagnosed these patients with irritable bowel syndrome and excluded organic disease as a cause of the child's abdominal pain.

Ages Eligible for Study:   13 Years to 18 Years
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • All children should fulfill Rome ll criteria for IBS.
  • Organic disease has been excluded.
  • Age 13-18 years.
  • Have active symptoms for at least 2 weeks prior to randomization. A minimum of 4.0 on the 7-point Likert scale for the two weeks prior to randomization on the GSRS-IBS composite pain score will be required.
  • Diarrhea predominant IBS: Diarrhea is defined as increased stool frequency more than 3 times daily or change in form to loose or watery stools.

Exclusion Criteria:

  • Children not fulfilling the inclusion criteria.
  • Children receiving medication for the treatment of irritable bowel syndrome within 2 weeks of randomization.
  • Children receiving antibiotic therapy or other probiotic agents within 4 weeks of randomization.
  • Children receiving other medication known to cause abdominal pain.
  • Children diagnosed with any of the following GI disorders: IBD (Crohn's disease or UC), Celiac disease, Gastroparesis, abdominal adhesions, Gastrointestinal perforation, Gastrointestinal obstruction and/or stricture, chronic or recurrent pancreatitis.
  • Children who had undergone previous abdominal surgery (with the exception of uncomplicated appendectomy or cholecystectomy greater than or equal to 6 months prior to enrollment).
  • Children with a history of any disease that may affect bowel motility such as diabetes mellitus, or poorly controlled hypo/hyperthyroidism.
  • Children with immune deficiency, on immune-suppressants, or have active psychiatric, neurological, metabolic, renal, hepatic, infectious, hematological, cardiovascular or pulmonary disease.
  • Children with a history of malignancy.
