Lactobacillus reuteri DSM 17938 for the Management of Functional Abdominal Pain in Childhood: A Randomized, Double-Blind, Placebo-Controlled Trial

Abstract

To determine whether administration of Lactobacillus reuteri DSM 17938 is beneficial in functional abdominal pain (FAP) of childhood. A total of 101 children, aged 6-15years, who fulfilled the Rome III criteria for FAP were enrolled in a randomized double-blind, placebo-controlled trial, and were randomly assigned to receive either L reuteri DSM 17938 or placebo for 4weeks, with further follow-up of additional 4weeks. Response to therapy was based on a self-reported daily questionnaire monitoring frequency and intensity of abdominal pain, using the faces scoring system by Hicks. L reuteri (n=47) was significantly superior to placebo (n=46) in relieving frequency (1.9±0.8 vs 3.6±1.7 episodes/wk, P<.02) and intensity (4.3±2.2 vs 7.2±3.1 Hicks score/wk, P<.01) of abdominal pain following 4weeks of supplementation. There was no difference in school absenteeism rate or other gastrointestinal symptoms, except for a lower incidence of perceived abdominal distention and bloating, favoring L reuteri. L reuteri DSM 17938, compared with placebo, significantly reduced the frequency and intensity of FAP in children. ClicalTrials.gov: NCT01180556.
