The purpose of this study is to evaluate the effects of long acting mesalamine (Lialda) in patients with Post-Infective Irritable Bowel Syndrome (PI-IBS). The investigators will evaluate gastrointestinal symptoms, IBS specific quality of life (IBS-QOL), and plasma cytokines before and after treatment with Lialda.

Condition Intervention Phase
Irritable Bowel Syndrome Drug: Mesalamine Drug: Placebo Phase 3

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Triple (Participant, Care Provider, Investigator)
Primary Purpose: Treatment
Official Title: The Effect of Long-Acting Mesalamine on Post-Infective Irritable Bowel Syndrome- A Pilot Study

Primary Outcome Measures:
  • Change from baseline in gastrointestinal symptoms and IBS specific quality of life after an 8 week treatment period [ Time Frame: Baseline and 8 weeks ]

Estimated Enrollment: 68
Study Start Date: June 2010
Estimated Study Completion Date: December 2017
Estimated Primary Completion Date: December 2017 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Placebo
This arm will include those who are randomized to the placebo
Drug: Placebo
This is an inactive pill
Other Name: Inactive drug
Experimental: Mesalamine
This arm is for subjects randomized to the study drug, Mesalamine
Drug: Mesalamine
2 1.2g tablets once daily for 8 weeks. Patients randomized 50/50 to either Mesalamine or the Placebo
Other Name: Lialda

Detailed Description:

This study will test long acting mesalamine in the management of PI-IBS. It has the potential to improve QOL and perhaps gastrointestinal symptoms, in patients with PI-IBS. The results of this study, if positive, will provide preliminary data for a large scale clinical trial.

This study will also provide information about plasma cytokines in patients with PI-IBS and whether improvement in symptoms correlates with improvement in plasma cytokines.
