Halkjær et al searched systematically nine articles including 48 patients, and concluded that fecal microbiota transplantation (FMT) can be an ideal treatment option for irritable bowel syndrome (IBS) subjects. Regardless of the few successes in current traditional therapies (change in diet, herbal medicine and antibiotics) in IBS, a sharp increase in interests in the FMT option has been reported in the current century. However, there is a long list of unclear issues concerning the application of FMT for the treatment of IBS...

Dysbiosis plays a major role in the etiology of inflammatory bowel disease (IBD). Fecal microbiota transplantation (FMT) is a new promising option for IBD treatment. We aimed to assess the effectiveness of a two-week FMT course in children with IBD. Ten patients, 10-17 years of age with moderate to severe IBD received a course of eight doses of freshly prepared FMT via a naso-duodenal tube or gastroscopy. All of the patients had pancolitis. There were eight cases of ulcerative colitis (UC) and two of Crohn's disease (CD)...

BACKGROUND: Malleolar fracture, which is present in 37-53% of human ankle osteoarthritis (OA), is the most common type of fracture in the ankle joint. In spite of this, no rat animal model has been developed for this type of injury to date. Here, we established a rat ankle post-traumatic OA (PTOA) model induced by malleolar fracture; this model will be useful in ankle OA research. METHODS: Two-month-old male Sprague Dawley (SD) rats were randomized into 2 groups (n = 19 per group): 1) malleolus articular fracture, dislocation, and immediate reduction on the right joints and 2) malleolus articular fracture on the right ankle...

Visual dysfunction is common in patients with Parkinson's disease (PD). The objective of this study was to investigate the perceived impact of visual dysfunction and especially color vision loss on PD patients, and to identify retinal and disease factors associated with color vision. Thirty PD patients and thirty-four healthy controls were included. Participants performed the Farnsworth-Munsell Hue-100 test (FMT). Patients answered the National Eye Institute Visual Function Questionnaire (NEI-VFQ), Unified Parkinson's Disease Rating Scale (UPDRS) assessment, and underwent optical coherence tomography with measurement of retinal nerve fiber layer, ganglion cell layer + inner plexiform layer (GCIPL), and outer nuclear and photoreceptor layer...

Fecal microbiota transplantation (FMT), also known as fecal bacteriotherapy or fecal infusion, consists of injection of a liquid filtrate of feces from a healthy donor into the gastrointestinal tract of a recipient individual. FMT has been proposed as a therapeutic approach for functional diseases of the gastrointestinal tract by reestablishment of a wide diversity of intestinal flora. Clostridium difficile infection (CDI) treatment guideline from American Gastroenterology Association (AGA) recommends that FMT can be used as the treatment protocols of relapse CDI...

The mucosal immune system and the microbiota in the intestinal tract have recently been shown to play a key role in the pathogenesis of inflammatory bowel disease (IBD). Both of these can be influenced by food. Thus, we propose dietary intervention as a therapeutic option for IBD. In this review, we discuss the interaction of the intestinal mucosal immune system and the intestinal microbiota in the context of IBD. In addition, we discuss the impact of food components on immune responses in IBD. Finally, we address the current evidence of how this interaction (i...

Mycobacterium tuberculosis is a major health threat, necessitating novel drug targets. Protein synthesis in bacteria uses initiator tRNAi charged with formylated methionine residue. Deletion of the formylase gene, tRNA(fMet)-formyl transferase (fmt), causes severe growth-retardation in E. coli and in S. pneumoniae, but not in P. aeruginosa or S. aureus. fmt was predicted to be essential in M. tuberculosis by transposon library analysis, but this was never formally tested in any mycobacteria. We performed a targeted deletion of fmt in M...

Patients with severe alcoholic hepatitis (SAH) have high mortality in the presence of steroid unresponsiveness in the absence of clear treatment recommendations. Liver transplantation is the curative option in such cases but is controversial in the wake of severe infections, post-transplant recidivism and long waiting on deceased donor listing. Animal and human studies have shed light on the beneficial effects of gut microbiota modulation in alcoholic liver disease. We present the first report of faecal microbiota transplantation (FMT) in a steroid non-responder in whom, clinical, biochemical and liver disease severity scores improved post-FMT and demonstrate distinct bacterial population changes pre-FMT and post-FMT...

Chickens of good and poor feed efficiency (FE) have been shown to differ in their intestinal microbiota composition. This study investigated differences in the fecal bacterial community of good and poor feed efficient chickens at 16 and 29 days post-hatch (dph) and evaluated whether a fecal microbiota transplant (FMT) from feed efficient donors early in life can affect the fecal microbiota in chickens at 16 and 29 dph, chicken's FE and nutrient retention at four weeks of age. One-hundred-ten chickens were inoculated with a FMT or a control transplant (CT) on 1, 6 and 9 dph and ranked according to residual feed intake (RFI; metric for FE) on 30 dph...

BACKGROUND: Irritable bowel syndrome (IBS) is a common condition characterised by abdominal pain, bloating, and poor quality of life. IBS might be caused by a gut dysbiosis. We aimed to compare faecal microbiota transplantation (FMT) with placebo in patients with IBS. METHODS: In this double-blind, randomised, placebo-controlled, parallel-group, single-centre study, we enrolled patients with IBS with diarrhoea or with diarrhoea and constipation (excluding dominating constipation) defined by the ROME III criteria, scored as moderate to severe according to the IBS severity scoring system (IBS-SSS; a score of ≥175)...

AIM: To investigate whether fecal microbiota transplantation (FMT) prevents hepatic encephalopathy (HE) in rats with carbon tetrachloride (CCl4)-induced acute hepatic dysfunction. METHODS: A rat model of HE was established with CCl4. Rat behaviors and spatial learning capability were observed, and hepatic necrosis, intestinal mucosal barrier, serum ammonia levels and intestinal permeability were determined in HE rats receiving FMT treatment. Furthermore, the expression of tight junction proteins (Claudin-1, Claudin-6 and Occludin), Toll-like receptor (TLR) 4/TLR9, interleukin (IL)-1β, IL-6 and tumor necrosis factor (TNF)-α was examined...

Immune checkpoint inhibitors (ICI) targeting the PD-1/PD-L1 axis induce sustained clinical responses in a sizeable minority of cancer patients. Here, we show that primary resistance to ICI can be due to abnormal gut microbiome composition. Antibiotics (ATB) inhibited the clinical benefit of ICI in patients with advanced cancer. Fecal microbiota transplantation (FMT) from cancer patients who responded to ICI (but not from non-responding patients) into germ-free or ATB-treated mice ameliorated the antitumor effects of PD-1 blockade...

Fecal microbiota transplantation (FMT) is effective in recurrent Clostridium difficile infection (rCDI). Knowledge of the safety and efficacy of FMT treatment in immune deficient patients is scarce. FMT has been suggested as a potential method for an increasing number of new indications besides rCDI. Among our FMT-treated rCDI patients, we reviewed those with major comorbidities: two human immunodeficiency virus patients, six haemodialysis patients, two kidney transplant patients, two liver transplant patients and a patient with chronic lymphatic leukaemia...

The purpose of this study is to propose a strategy for organ reconstruction in fluorescence molecular tomography (FMT) without prior information from other imaging modalities, and to overcome the high cost and ionizing radiation caused by the traditional structural prior strategy. The proposed strategy is designed as an iterative architecture to solve the inverse problem of FMT. In each iteration, a short time Fourier transform (STFT) based algorithm is used to extract the self-prior information in the space-frequency energy spectrum with the assumption that the regions with higher fluorescence concentration have larger energy intensity, then the cost function of the inverse problem is modified by the self-prior information, and lastly an iterative Laplacian regularization algorithm is conducted to solve the updated inverse problem and obtains the reconstruction results...

Clostridium difficile infection (CDI) is one of the most common nosocomial infections. Dysbiosis of the gut microbiota due to consumption of antibiotics is a major contributor to CDI. Recently, fecal microbiota transplantation (FMT) has been applied to treat CDI. However, FMT has important limitations including uncontrolled exposure to pathogens and standardization issues. Therefore, it is necessary to evaluate alternative treatment methods, such as bacteriotherapy, as well as the mechanism through which beneficial bacteria inhibit the growth of C...
