(2022). Probiotics therapy for adults with diarrhea -predominant irritable bowel syndrome: a systematic review and meta-analysis of 10 RCTs. International Journal of Colorectal Disease, 37(11), 2263–2276. https://doi.org/10.1007/s00384-022-04261-0 Background Irritable bowel syndrome (IBS) is a common functional gastrointestinal disorder with over 23% prevalence worldwide. It is divided into four subtypes: constipation-predominant IBS (IBS-C), diarrhea -predominant IBS (IBS-D), mixed IBS (IBS-M), and unclassified IBS (IBS-U). IBS-D, the most common subtype, is characterized by frequent diarrhea accompanied by abdominal distension or abdominal pain. It accounts for about one-third of total IBS cases and significantly affects patients' quality of life and contributes to the economic burden. The etiology and pathogenesis of IBS-D are still unclear, but studies suggest it is associated with dysbiosis of the gut microbiota, visceral hypersensitivity, stress, genetics, diet, and psychosocial factors. Current treatments include alosetron hydrochloride, selective M3 receptor antagonists, loxiglumide , somatostatin, oxytocin, tachykinin, antispasmodics, antimotility drugs, and anti-depressants. Probiotics, which can prevent recurrent pouchitis and Clostridioides difficile diarrhea , have been shown to be beneficial for IBS patients.
