Clinical Trial Summary

The purpose of this study is to evaluate the efficacy of a treatment with Lactobacillus casei DG in the reduction of the painful symptoms in patients affected by irritable bowel syndrome. After that, the secondary object is to evaluate if the reduction of painful symptoms is related to a relevant reduction of trypsin and tryptase in colonic mucosa.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Intensity of painful symptoms	The efficacy of the treatment will be evaluated recording the intensity of the painful symptoms associated with irritable bowel syndrome for the duration of the study. The intensity of abdominal pain will be recorded daily by the patient in a diary using a semi-quantitative scale (Likert) to 6 points, from 0 (absent) to 5 (very severe).	4 weeks	No
Secondary	Level of trypsin and tryptase in colonic mucosa	Will evaluate the reduction in the levels of trypsin and tryptase in the colonic mucosa by collecting biopsies from the sigmoid colon and samples colonic lavage fluid and subsequent histological and molecular examination with extraction of m-RNA and proteins.	4 weeks	No
