Outcomes

Primary Outcome Measures

Severity of abdominal pain
Clinical endpoint: Average daily severity of abdominal pain on a 0-10 scale [ Time Frame: Week 0 to week 12 ] [ Designated as safety issue: No ] Days with urgency [ Time Frame: Week 0 to week 12 ] [ Designated as safety issue: No ] Mean stool consistency using Bristol Stool Form Score [ Time Frame: Week 0 to week 12 ] [ Designated as safety issue: No ] Global satisfaction with control of IBS symptoms as assessed from the answer to the question "Have you had satisfactory relief of your IBS symptoms this week? Yes / No. "

Secondary Outcome Measures

Mucosal byopsies
Effect of pentoxifylline treatment from mucosal byopsies on: epithelial morphology; mucosal immune cell subsets; changes of gene expression of genes related to intestinal epithelial barrier component( tight junctions)

5. Study Description

Brief Summary
The purpose of this study is to determine the therapeutics effectiveness of oral pentoxifylline treatment in patients with IBS.
Detailed Description
Disruption of the intestinal epithelial barrier is part of the pathophysiology of IBS favoring immune activation present in the mucosa of these patients and the development of symptoms in IBS. To evaluate the effect of treatment with pentoxifylline (PTX) in patients with IBS related to clinical response and modulation of the components of the epithelial barrier at the level of intestinal mucosa.
