Brief summary
A randomized, multicenter, placebo-controlled, double blind study in two parallel groups testing the efficacy of daily oral supplementation with the probiotic L.reuteri DSM17938 compared to placebo in increasing the number of spontaneous bowel movements in infants and children with functional constipation.
Detailed description
Functional constipation in infants up to 4 years of age is defined according to Rome III criteria (Hyman 2006). The diagnose must include 1 month of at least two of the following criteria: two or fewer defecations per week; at least 1 episode per week of incontinence after the acquisition of toilet skills; history of excessive stool retention; history of painful or hard bowel movements; presence of a large faecal mass in the rectum; history of large-diameter stools that may obstruct the toilet. Accompanying symptoms may include irritability, decreased appetite and/or early satiety. The accompanying symptoms disappear immediately following passage of a large stool. There is a growing interest for the use of probiotics in functional constipation as research suggests that probiotics could provide beneficial support in the traditional treatment arsenal although the mechanisms of actions are not completely understood. Wu et al have demonstrated that Lactobacillus reuteri DSM 17938 may have a region-specific intestinal effect on gut motility and therefore could be beneficial in treatment of constipation Lactobacillus reuteri DSM 17938 has shown significant favourable effects in adults (Ojetti 2014) and young children as described above (Coccorullo 2010, Olgac 2013). These studies require confirmation however. The present clinical study has been designed to strengthen the current available data that L. reuteri DSM 17938 has beneficial effects in infants and young children with functional constipation. We hypothesize that daily oral supplementation with the probiotic Lactobacillus reuteri DSM 17938 will effectively increase the number of spontaneous bowel movements in infants/children diagnosed with functional constipation according to Rome IV.
