BACKGROUND: A sensation of abdominal swelling (bloating) and actual increase in girth (distension) are troublesome features of irritable bowel syndrome (IBS), which is more common in patients with constipation, especially those with delayed transit.
AIM: To establish whether a fermented dairy product containing Bifidobacterium lactis DN-173 010 reduces distension in association with acceleration of gastrointestinal transit and improvement of symptoms in IBS with constipation.
METHODS: A single centre, randomized, double-blind, controlled, parallel group study in which patients consumed the test product or control product for 4 weeks. Distension, orocaecal and colonic transit and IBS symptoms were assessed on an intention-to-treat population of 34 patients.
RESULTS: Compared with control product, the test product resulted in a significant reduction in the percentage change in maximal distension [median difference - 39%, 95% CI (-78, -5); P = 0.02]and a trend towards reduced mean distension during the day [-1.52 cm (-3.33, 0.39); P = 0.096]. An acceleration of orocaecal [-1.2 h (-2.3,0); P = 0.049]as well as colonic [-12.2 h (-22.8, -1.6); P = 0.026]transit was observed and overall symptom severity [-0.5 (-1.0, -0.05); P = 0.032]also improved.
CONCLUSIONS: This probiotic resulted in improvements in objectively measured abdominal girth and gastrointestinal transit, as well as reduced symptomatology. These data support the concept that accelerating transit is a useful strategy for treating distension.

OBJECTIVES: To evaluate the beneficial effects of Lactobacillus reuteri (DSM 17938) in infants with functional chronic constipation.
STUDY DESIGN: A double-blind, placebo-controlled, randomized study was conducted from January 2008 to December 2008 in 44 consecutive infants at least 6 months old (mean age+/-SD, 8.2+/-2.4 SD; male/female, 24/20) admitted to the Gastrointestinal Endoscopy and Motility Unit of the Department of Pediatrics, University "Federico II" of Naples, with a diagnosis of functional chronic constipation. The 44 infants with chronic constipation were randomly assigned to 2 groups: group A (n=22) received supplementation with the probiotic L reuteri (DSM 17938) and group B (n=22) received an identical placebo. Primary outcome measures were frequency of bowel movements per week, stool consistency, and presence of inconsolable crying episodes, recorded in a daily diary by parents.
RESULTS: Infants receiving L reuteri (DSM 17938) had a significantly higher frequency of bowel movements than infants receiving a placebo at week 2 (P=.042), week 4 (P=.008), and week 8 (P=.027) ofsupplementation. In the L reuteri group, the stool consistency was reported as hard in 19 infants (86.4%) at baseline, in 11 infants (50%) at week 2, and in 4 infants (18.2%) at weeks 4 and 8. However, there was no significant difference between L reuteri and placebo groups in the stool consistency at all weeks (P=.63, week 2; P=.38, week 4; P=.48, week 8). Similarly, there was no statistically difference in the 2 groups in the presence of inconsolable crying episodes. No adverse effects were reported.
CONCLUSIONS: The administration of L reuteri (DSM 17938) in infants with chronic constipation had a positive effect on bowel frequency, even when there was no improvement in stool consistency and episodes of inconsolable crying episodes. Because of their safety profile, probiotics may be an attractive option in the treatment of functional constipation.
