Efficacy of Mesalamine in Diarrhea-predominant Irritable Bowel Syndrome (dIBS)
The purpose of this study is to find whether treating patients with diarrhea predominant Irritable Bowel Syndrome (IBS) with an anti-inflammatory drug called Mesalamine will help improve their symptoms of diarrhea, bloating and abdominal pain.
Irritable bowel syndrome (IBS) is a common gastrointestinal disorder affecting about 20% of the United States population and comprising almost 50% of referrals to gastroenterology practices. Although the pathophysiology of IBS is poorly understood, more recently, both inflammation and an increased intestinal permeability have been identified as potential factors in the etiology of diarrhea-predominant IBS patients(dIBS). Despite the potential of an inflammatory etiology for IBS, few studies have examined the efficacy of anti-inflammatory agents such as mesalamine in patients with IBS. The primary objective of our study is to determine the efficacy of Apriso™ (Salix Pharmaceuticals Inc), a long-acting mesalamine, in the treatment of patients with dIBS. Apriso™, is a mesalamine approved by the Food and Drug Administration (FDA) on October 31, 2008 for the maintenance of remission in patients with active, mild to moderate ulcerative colitis. The investigators will perform a randomized, double-blind, cross-over trial of mesalamine compared to placebo in patients with dIBS. This study will analyze both the objective and subjective measures of improvement in IBS symptoms. The subjective measures will include improvements in the overall symptom severity scores and the Global Improvement Scale (GIS) and the objective measures will include histological measures of inflammation as well as improvements in the intestinal membrane permeability of treated subjects. The investigators will demonstrate that during the 12 weeks treatment period with mesalamine, subjects will have improvements in their overall symptom scores, GIS scores, and will have a reduction in intestinal inflammation and also prohibit a likely improvement in Intestinal membrane permeability.

Medical and Biotech [MESH] Definitions
Colonic Diseases, Functional
Chronic or recurrent colonic disorders without an identifiable structural or biochemical explanation. The widely recognized IRRITABLE BOWEL SYNDROME falls into this category.
Irritable Bowel Syndrome
A disorder with chronic or recurrent colonic symptoms without a clearcut etiology. This condition is characterized by chronic or recurrent ABDOMINAL PAIN, bloating, MUCUS in FECES, and an erratic disturbance of DEFECATION.
A drug that is used in the management of inflammatory bowel diseases. Its activity is generally considered to lie in its metabolic breakdown product, 5-aminosalicylic acid (see MESALAMINE) released in the colon. (From Martindale, The Extra Pharmacopoeia, 30th ed, p907)
An anti-inflammatory agent, structurally related to the SALICYLATES, which is active in INFLAMMATORY BOWEL DISEASE. It is considered to be the active moiety of SULPHASALAZINE. (From Martindale, The Extra Pharmacopoeia, 30th ed)
Short Bowel Syndrome
A malabsorption syndrome resulting from extensive operative resection of the SMALL INTESTINE, the absorptive region of the GASTROINTESTINAL TRACT.
The primary purpose of this study is to evaluate the effects of BMS-562086 on small bowel and colonic transits in female subjects with diarrhea-predominant irritable bowel syndrome (D-IBS)

PURPOSE: To study the therapeutic effects of probiotic Escherichia coli Nissle 1917 (EcN) in irritable bowel syndrome (IBS) and identify subgroups benefiting most....
Evidence suggests that gut flora may play an important role in the pathophysiology of the irritable bowel syndrome (IBS). We evaluated rifaximin, a minimally absorbed antibiotic, as treatment for IBS.
Probiotic agents have received growing attention in recent years as an alternative therapeutic tool in the management of irritable bowel syndrome. In this article, we will discuss the rationale that s...
PURPOSE: The diagnosis of irritable bowel syndrome is symptom based, and colonoscopy is the most direct way to rule out organic colonic diseases. It is controversial on the necessity of colonoscopy fo...
