The characteristics of intestinal microbial communities may be affected by changes in the pathophysiology of patients with end-stage liver disease. Here, we focused on the characteristics of intestinal fecal microbial communities in post-liver transplantation (LT) patients in comparison with those in the same individuals pre-LT and in healthy individuals. The fecal microbial communities were analyzed via MiSeq-PE250 sequencing of the V4 region of 16S ribosomal RNA and were then compared between groups. We found that the gut microbiota of patients with severe liver disease who were awaiting LT was significantly different from that of healthy controls, as represented by the first principal component (p = 0...

BACKGROUND/AIMS: Dysbiosis is associated with various systemic disorders including irritable bowel syndrome (IBS). Fecal microbiota transplantation (FMT) might restore intestinal microbial balance. The study aimed to determine the safety and efficacy of FMT in IBS patients, as well as also positive predictors for FMT. METHODS: This was a single-arm, open-label study. Eligible patients were diagnosed based on Rome III Diagnostic Criteria. Fecal materials were administered to the patient via colonoscopy...

Therapeutic strategies in ulcerative colitis are evolving. A personalized and optimal use of available drugs and the integration of new drug classes are the cornerstones underpinning the new treatment paradigms. Areas covered: A structured literature search in Medline and PubMed, Cochrane meta-analyses, and abstracts of international congresses has been performed to review therapeutic approaches to ulcerative colitis. The primary therapeutic objective of therapy is to achieve clinical remission since persistence of active disease, even if mild, leads to a significant reduction in quality of life...

The history of fecal microbiota transplantation (FMT) dates back even to ancient China. Recently, scientific studies have been looking into FMT as a promising treatment of various diseases, while in the process teaching us about the interaction between the human host and its resident microbial communities. Current research focuses mainly on Clostridium difficile infections, however interest is rising in other areas such as inflammatory bowel disease (IBD) and the metabolic syndrome. With regard to the latter, the intestinal microbiota might be causally related to the progression of insulin resistance and diabetes...

Inflammatory bowel disease (IBD) is a complex set of diseases that lead to chronic inflammation in the gastrointestinal tract. Although the etiology of IBD is not fully understood, it is well-known that the intestinal microbiota is associated with the development and maintenance of IBD. Manipulation of the gut microbiota, therefore, may represent a target for IBD therapy. Fecal microbiota transplantation (FMT), where fecal microbiota from a healthy donor is transplanted into a patient's GI tract, is already a successful therapy for Clostridium difficile infection...

Fecal microbiota transplantation (FMT) is a remarkably efficacious therapy for recurrent or refractory Clostridium difficile infection (CDI), but not standardized. This work is to determine whether frozen FMT is as effective as fresh FMT. Meta-analysis showed that frozen FMT was as effective as fresh FMT, both pooled first effective rate (65.0% (95% CI 57.0-73.0%) vs. 65.0% (95% CI 57.0-73.0%), P=0.962) and pooled second effective rate (95.0% (95% CI 91.0-99.0%) vs. 95.0% (95% CI 92.0-99.0%), P=0.880). In conclusion, among patients with recurrent or refractory CDI, frozen FMT is as effective as fresh FMT...

Fecal microbiota transplantation (FMT) is a promising strategy that involves reconstruction of gut microbiota. Recently, it has been considered as a treatment of Crohn's disease (CD) and certain neurological diseases. Here, to the best of our knowledge, we report the first case that used FMT to achieve remission of intestinal and neurological symptoms in a girl with CD and a 17-year history of epilepsy. During the 20 mo of follow-up, FMT has proved its efficacy in preventing relapse of seizures after withdrawing the antiepileptic drugs...

Advances in microbial analysis have provided new insights into the complex interactions between the host and gut microbiota. An imbalance in the gut microbiota (dysbiosis) is associated with various disorders and their pathogenesis. Furthermore, in allogeneic stem cell transplantation, increasing evidence indicates that the gut microbiota is closely associated with acute graft-versus-host disease (GVHD) and transplant outcomes, suggesting that its manipulation could be a new treatment strategy for this acute condition...

Upon hospitalization, up to 15.5% of patients are already colonized with a toxigenic Clostridium difficile strain (TCD). The rate of asymptomatic colonization is 0-3% in healthy adults and up to 20-40% in hospitalized patients. The incidence and mortality of C. difficile infection (CDI) has significantly increased during recent years. Mortality lies between 3 and 14%. CDI is generally caused by intestinal dysbiosis, which can be triggered by various factors, including antibiotics or immune suppressants. If CDI occurs, ongoing antibiotic therapy should be discontinued...

Severe acute malnutrition is the world-leading cause of children under-five's death. Recent metagenomics studies have established a link between gut microbiota and severe acute malnutrition, describing an immaturity with a striking depletion in oxygen-sensitive prokaryotes. Amoxicillin and therapeutic diet cure most of the children with severe acute malnutrition but an irreversible disruption of the gut microbiota is suspected in the refractory and most severe cases. In these cases, therapeutic diet may be unable to reverse the microbiota alteration leading to persistent impaired development or death...

Recurrent hepatic encephalopathy (HE) is a leading cause of readmission despite standard of care (SOC) associated with microbial dysbiosis. Fecal microbiota transplantation (FMT) may improve dysbiosis; however, it has not been studied in HE. We aimed to define whether FMT using a rationally-derived stool donor is safe in recurrent HE compared to SOC alone. An open-label, randomized clinical trial with a 5 month follow-up in outpatient cirrhotic men with recurrent HE on SOC was conducted with 1:1 randomization...

Although allogeneic stem cell transplantation (allo-SCT) is a potentially curative treatment for various hematological diseases, acute graft-versus-host disease (GVHD) is a major cause of morbidity and mortality, and its management is clinically important. Advances in biological techniques have led to great progress in understanding the complex interactions between the host and the gut microbiota. The gut microbiota clearly modulates the immune response and is associated with the pathogenesis of various disorders...

We retrospectively analyzed a cohort of 109 subjects treated for rCDI with FMT at tertiary referral center between 2011 and 2014 to determine risk factors for FMT failure.. In a multivariate analysis, failure to use an oral vancomycin taper preceding FMT was associated with a significant risk of FMT failure (odds ratio [95% CI], 0.15 [0.007-0.40]).

Background: The availability of fresh stool samples is a prerequisite in most gut microbiota functional studies. Objective: Strategies for amplification and long-term gut microbiota preservation from fecal samples would favor sample sharing, help comparisons and reproducibility over time and between laboratories, and improve the safety and ethical issues surrounding fecal microbiota transplantations. Design: Taking advantage of in vitro gut-simulating systems, we amplified the microbial repertoire of a fresh fecal sample and assessed the viability and resuscitation of microbes after preservation with some common intracellular and extracellular acting cryoprotective agents (CPAs), alone and in different combinations...

Fecal microbiota transplant (FMT) has emerged as an effective and increasingly popular therapy for recurrent Clostridium difficile infections in patients that have failed standard antimicrobial treatment. Patient access to FMT is hampered by the logistics of manufacturing, storing, and delivering the inocula. An observational study describes the development and clinical efficacy of freeze-dried FMT capsules for oral administration. While awaiting the emergence of defined bacterial therapeutics for Clostridium difficile infections, this refinement of FMT is an encouraging step toward simplifying FMT treatment...

After acute infectious gastroenteritis, up to thirty percent of patients present prolonged gastrointestinal symptoms and a part of those affected patients can have the diagnostic criteria for postinfectious irritable bowel syndrome. Treatment is symptom directed rather than curative and includes agents prescribed for the treatment of irritable bowel syndrome in general. Prophylaxis or early treatment of acute bacterial diarrhea may reduce the risk of postinfectious irritable bowel syndrome development by reducing the occurrence, duration, and severity of the chronic inflammation and mucosal alterations (all these believed to play an important role in disease persistence)...

OBJECTIVE: Emerging pre-clinical evidence has shown that the bidirectional signaling between the gastrointestinal tract and the brain, the so-called gut-brain axis, plays an important role in both host metabolism and behavior. In this review, we will discuss the potential mechanisms of the brain-gut axis in relation to the pathophysiology of metabolic syndrome. METHODS: A selective literature review was conducted to evaluate gastrointestinal and brain interactions...
