Gut microbiota and therapeutic approaches for dysbiosis in irritable bowel syndrome: Recent developments and future perspectives.

Gut microbiota and therapeutic approaches for dysbiosis in irritable bowel syndrome: Recent developments and future perspectives. Turk J Med Sci. 2020 Mar 28;: Authors: Dale HF, Lied GA Abstract Increased knowledge regarding the implications of gut microbiota in irritable bowel syndrome (IBS), suggest that a disturbed intestinal microenvironment (dysbiosis) might promote the development and maintenance of IBS symptoms and effects several pathways in the pathology of this multifactorial disease. Accordingly, manipulation of the gut microbiota in order to improve IBS symptoms has the last decade evolved as a novel treatment strategy. Several different approaches have been investigated in order to improve the gut microbiota composition. Dietary modifications including supplementation with fibers, prebiotics and probiotics are shown to improve symptoms and composition of gut microbiota in IBS, however the exact probiotic mixture beneficial for each individual remains to be identified. The use of antibiotics still needs confirmation, although promising results have been reported with use of rifaximin. Fecal microbiota transplantation (FMT) has recently gained a lot of attention, and several placebo-controlled trials investigating FMT pose promising results regarding symptom reduction and gut microbiota manipulation in IBS. However, more data regarding long-term effects is needed before FMT can be integrated as a customised treatment for IBS in the clinical rou...

Rationale: Myelodysplastic syndrome (MDS) can be complicated with Crohn disease (CD). Irritable bowel disease (IBD) associated with MDS has already been reported in the past; however, hematopoietic stem cell transplantation (HSCT) is rarely performed. Herein, we report a case of CD with MDS for HSCT. Patient concerns: A 41-year-old man was hospitalized due to abdominal pain and intermittent fever for 40 days. Two years later, he was readmitted due to abdominal pain and diarrhea with fever for 10 days. Diagnosis: Symptoms, laboratory examinations, and imaging findings of the patient were indicative of CD complicated...

Abstract The human gut microbiota comprises of a complex and diverse array of microorganisms, and over the years the interaction between human diseases and the gut microbiota has become a subject of growing interest. Disturbed microbial milieu in the gastrointestinal tract is central to the pathogenesis of several diseases including antibiotic-associated diarrhea and Clostridioides difficile infection (CDI). Manipulation of this microbial milieu to restore balance by microbial replacement therapies has proven to be a safe and effective treatment for recurrent CDI. There is considerable heterogeneity in various asp...

Nature Reviews Gastroenterology &Hepatology, Published online: 27 February 2020; doi:10.1038/s41575-020-0282-zFaecal microbiota transplantation (FMT) aims to restore an altered microbiota and has been suggested as a potential treatment option for irritable bowel syndrome (IBS), among other diseases. A new study suggests that the use of a so-called superdonor is necessary to successfully treat patients with IBS using FMT.

Uroguanylin activates guanylate cyclase-C to regulate intestinal electrolyte and water transport. Aim. To quantify uroguanylin immunoreactive cells density in the duodenum of diarrhea-predominant IBS (IBS-D) patients compared to controls and to investigate the effect of fecal microbiota transplantation (FMT) on these cell densities. Method. Twelve patients with IBS-D according to Rome III criteria were included. The cause was identified a...

CONCLUSION: Of the biological agents, vedolizumab and infliximab were the most effective, suggesting that biological agents are still a better choice. Nevertheless, tofacitinib and FMT may be promising alternatives with high efficacies. However, more safety and maintenance studies need to be conducted in future for the acquisition of more accurate results.Abbreviations: FMT: Fecal microbiota transplantation; UC: Ulcerative colitis; RCTs: Randomized controlled trials; IBD: Inflammatory bowel disease; CD: Crohn's disease; IBS: Irritable bowel syndrome; CDI: Clostridium difficile infections; ITT: Intention-to-treat; RR: Relat...

Purpose of review To provide an overview of recent studies exploring the gut microbiota in pathogenesis and treatment of irritable bowel syndrome (IBS). Recent findings Primary bacterial gut disturbances have been linked to the development and severity of IBS. Dysbiosis, or alteration in the normal intestinal flora, modulates intestinal permeability, inflammation, gut motility and likely quality of life. These biomechanical changes are associated with enteric and central nervous system processing as well. When compared to healthy controls, IBS patients display poor quality of life measures and are at increased risk of...

Authors: Wang Y, Zheng F, Liu S, Luo H Abstract Irritable bowel syndrome is a functional disorder characterized by abdominal pain or discomfort associated with altered bowel habits. Due to the uncertainty of the pathogenesis of IBS and the diversity of its clinical manifestations, IBS cannot be completely cured. Increasing evidence suggests the key role of altered intestinal microbiota in the pathogenesis of IBS. Therefore, attention is being shifted to adjusting the changes in intestinal microbiota to control IBS symptoms. Fecal microbiota transplantation (FMT), antibiotics, probiotics, and synbiotics are currentl...
