Evaluate the Effect of Synbiotics in Irritable Bowel Syndrome

Irritable Bowel Syndrome (IBS) is a brain-gut-disorder characterized by a chronic relapsing-remitting nature of symptoms, including abdominal pain and altered bowel habits. Symptoms most likely result from complex interactions between several biological, psychological and social factors. Probiotic supplements are thought to improve IBS symptoms through manipulation of the gut microbiota. Some studies have suggested that different strains of probiotics may improve abdominal pain and reduce visceral hypersensitivity by modulation of expression of neurotransmitters and receptors involved in the modulation of pain, such as the opioid receptor or the cannabinoid receptor. In addition, probiotics have been shown to reduce intestinal cytokine secretion and improve epithelial barrier function in a mice model of intestinal inflammation. Bifidobacteria and Streptococci strains had previously demonstrated efficacy in achieving symptom improvement in IBS patients. Thus, there is potential for SMT04, a health supplement, to be an option for IBS patients.
