Treatment of Postinfectious Irritable Bowel Syndrome and Noninfective Irritable Bowel Syndrome With Gelsectan

348/28-7-2021

Irritable Bowel Syndrome (IBS) is one of the most common conditions diagnosed in gastroenterology practice. Acute infectious gastroenteritis represents the strongest known risk factor for IBS development; a condition known as post-infection IBS (PI-IBS). PI-IBS patients are more likely than sporadic IBS patients to exhibit a diarrhea-predominant phenotype. The investigators plan to prospectively recruit two groups of patients: patients with diarrhea-predominant post-infectious IBSand patients with diarrhea predominant classical IBS (non PI-IBS) who will be used as controls. Patients included in the study will receive for 28 days a capsule containing Tamarind seed polysaccharide containing xyloglucan, combined with a pea protein reticulated with grape seed extractand a prebiotic, the xilooligosaccharide (Gelsectan, Devintec Sagl) twice daily.
