Abstract

Summary: Aim : To investigate the effects of a probiotic formulation, VSL#3, on gastrointestinal transit and symptoms of patients with Rome II irritable bowel syndrome with predominant diarrhoea. Methods : Twenty‐five patients with diarrhoea‐predominant irritable bowel syndrome were randomly assigned to receive VSL#3 powder (450 billion lyophilized bacteria/day) or matching placebo twice daily for 8 weeks after a 2‐week run‐in period. Pre‐ and post‐treatment gastrointestinal transit measurements were performed in all patients. Patients recorded their bowel function and symptoms daily in a diary during the 10‐week study, which was powered to detect a 50% change in the primary colonic transit end‐point. Results : There were no significant differences in mean gastrointestinal transit measurements, bowel function scores or satisfactory global symptom relief between the two treatment groups, pre‐ or post‐therapy. Differences in abdominal bloating scores between treatments were borderline significant (P = 0.09, analysis of covariance). Further analysis revealed that abdominal bloating was reduced (P = 0.046) with VSL#3 [mean post‐ minus pre‐treatment score, − 13.7; 95% confidence interval (CI), − 2.5 to − 24.9], but not with placebo (P = 0.54) (mean post‐ minus pre‐treatment score, − 1.7; 95% CI, 7.1 to − 10.4). With the exception of changes in abdominal bloating, VSL#3 had no effect on other individual symptoms: abdominal pain, gas and urgency. All patients tolerated VSL#3 well. Conclusion : VSL#3 appears to be promising in the relief of abdominal bloating in patients with diarrhoea‐predominant irritable bowel syndrome. This is unrelated to an alteration in gastrointestinal or colonic transit.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
