Brief Summary

The diffusion of gastrointestinal (GI) chronic diseases is significantly increased during the last century in western countries. In the USA and Northern Europe, constipation is twofold the prevalence found in the East and Southern Europe. In Italy, constipation affects up to 15-17% of the whole adult population. Of them, more than half (about 10%) treats this disorder by assuming laxatives, while the remaining does not even assume drugs. A close relationship between intestinal environment and bacterial flora has been found. As a matter of fact changes in the intestinal physiology can modify the composition of bacterial flora as well as modifications in the intestinal microbiota can modify the physiology of the gut. The probiotic effects on the GI motility can be due to substances released by bacteria and/or products of their fermentation. Also, probiotic may indirectly act by the release of neuroendocrine factors and/or substances released by the immune system. Clinically, it has already been demonstrated that probiotics exert a positive effect on symptoms and intestinal habit in constipated IBS patients. In this framework, the idea to perform a long lasting intervention study in patients with functional constipation treated with probiotics sounds convincing. The present study is a randomized, double blind, placebo controlled, monocentric study, concerning the evaluation of efficacy of 3 months administration of Lactobacillus reuteri DSM 17938 in patients with functional constipation, as defined by the Rome criteria. Clinical, physiological, hematological and immunologic variables will be evaluated.

Outcome Measures

Primary Outcomes (1)

  • Improvement in gastrointestinal symptoms after 3 months of probiotic administration

    Validated and structured questionnaires to evaluate gastrointestinal symptoms, to confirm functional constipation diagnosis and to exclude IBS variant constipation. Score of gastrointestinal symptoms with Gastrointestinal Symptom Rating Score (GSRS); Constipation Symptom Score (CSS); Constipation QoL, Constipation Rome criteria, Diary for the symptoms and for intestinal behavior. These questionnaires will be administered at baseline, after 45 days of treatment, and at the end of treatment.

    Before the start of the study (Time 0) and after 90 days of treatment (Time 90)

Secondary Outcomes (2)

  • Changes in metabolic parameters after 3 months of probiotic administration

    Before the start of the study (time 0) and after 90 days of treatment (Time 90)

  • Changes in physiological parameters after 3 months of probiotic administration

    Before the start of the study (Time 0) and after 90 days of treatment (Time 90)
