The objective was to detect Gram-negative bacilli and Gram-positive cocci isolated from the environmental microbiota of the Intensive Care Unit (ICU) departments of Neonatology, Pediatrics, and Transplants (kidney, liver, and general) in a Lima hospital and determine their antimicrobial sensitivity. Eighty samples were obtained from inanimate surfaces using a wet swab. A total of 61 bacterial strains were identified, including Staphylococcus epidermis (46.0%), Alcaligenes sp. (21.3%), Pseudomonas aeruginosa (16...

Since 2013, several stool banks have been developed following publications reporting on clinical success of "Fecal Microbiota Transplantation" (FMT) for recurrent Clostridium difficile infections (CDI). However, protocols for donor screening, fecal suspension preparation and transfer of the fecal suspension differ between various countries and institutions. Moreover, no European consensus exists regarding the legislative aspects of the fecal suspension product. Internationally standardized recommendations about the above mentioned aspects have not yet been established...

Roux-en-Y gastric bypass (RYGB) and duodenal jejunal bypass (DJB), two different forms of bariatric surgery, are associated with improved glucose tolerance, but it is not clear whether the gut microbiota contributes to this effect. Here we used fa/fa rats as a model of impaired glucose tolerance to investigate whether (i) the microbiota varies between fa/fa and nondiabetic fa/+ rats; (ii) the microbiota of fa/fa rats is affected by RYGB and/or DJB; and (iii) surgically induced microbiota alterations contribute to glucose metabolism...

Approximately one-third of patients with Crohn's disease do not respond to conventional treatments, and some experience significant adverse effects, such as serious infections and lymphoma, and many patients require surgery due to complications. Increasing evidence suggests that specific changes in the composition of gut microbiota, termed as dysbiosis, are a common feature in patients with inflammatory bowel disease (IBD). Dysbiosis can lead to activation of the mucosal immune system, resulting in chronic inflammation and the development of mucosal lesions...

Alcoholic hepatitis manifests as a clinical syndrome characterized by recent jaundice and liver function deterioration in an actively drinking patient. The principal cause of alcoholic hepatitis is alcoholic steatohepatitis defined histologically by the coexistence of steatosis, hepatocyte ballooning and satellitosis. While non-severe alcoholic hepatitis usually responds to alcohol abstinence, severe alcoholic hepatitis, identified by Maddrey scoring ≥ 32, has a bad prognosis and is traditionally treated by a 28-day course of prednisone therapy...

Severe alcoholic hepatitis is implicated as a costly, worldwide public health issue with high morbidity and mortality. The one-month survival for severe alcoholic hepatitis is low with mortality rates high as 30%-50%. Abstinence from alcohol is the recommended first-line treatment. Although corticosteroids remain as the current evidence based option for selected patients with discriminant function > 32, improvement of short-term survival rate may be the only benefit. Identification of individuals with risk factors for the development of severe alcoholic hepatitis may provide insight to the diverse clinical spectrum and prognosis of the disease...

BACKGROUND: Clostridium difficile infection (CDI) is a major infectious disease focus for which fecal microbiota transplantation (FMT) has been used with success in various patient populations. METHODS: We conducted a retrospective study of FMT in immunocompetent and immunocompromised patients to review outcomes at our center, with a focus on identifying risk factors for FMT failure in solid organ transplant (SOT) patients. FMT was conducted using universal banked frozen stool via naso-duodenal tube in patients with recurrent CDI of 3 or more episodes per our institutional protocol...

Gut microbiota is critical for maintaining body immune homeostasis and thus affects tumor growth and therapeutic efficiency. Here, we investigated the link between microbiota and tumorgenesis in a mice model of subcutaneous melanoma cell transplantation, and explored the underlying mechanism. We found disruption of gut microbiota by pretreating mice with antibiotics promote tumor growth and remodeling the immune compartment within the primary tumor. Indeed, gut microbial dysbiosis reduced the infiltrated mature antigen-presenting cells of tumor, together with lower levels of co-stimulators, such as CD80, CD86 and MHCII, as well as defective Th1 cytokines, including IFNγ, TNFα, IL12p40, and IL12p35...

BACKGROUND: Gut microbiota play a key role in maintaining homeostasis in the human gut. Alterations in the gut microbial ecosystem predispose to Clostridium difficile infection (CDI) and gut inflammatory disorders such as inflammatory bowel disease (IBD). Fecal microbiota transplantation (FMT) from a healthy donor can restore gut microbial diversity and pathogen colonization resistance; consequently, it is now being investigated for its ability to improve inflammatory gut conditions such as IBD...

The use of fecal microbiota transplantation in recurrent Clostridium difficile infection and coexistent inflammatory bowel disease remains unclear. A 61-year-old man with ulcerative pancolitis was diagnosed with a third recurrence of Clostridium difficile infection, previously treated with metronidazole, vancomycin and fidaxomicin. Fecal microbiota transplantation of an unrelated healthy donor was performed by the lower route. After a twelve month follow-up, the patient remains asymptomatic without Clostridium difficile infection relapses or inflammatory bowel disease flare-ups...

The optimal delivery of faecal microbiota transplant (FMT) is unknown. In this observational single-centre study, we analyzed the 2-week cure rates all patients who received FMT from 2013-2016 according to route of delivery. Overall, nasogastric delivery of FMT was less effective than lower endoscopy. However, when patients were stratified by illness severity, nasogastric delivery achieved similar cure rates in healthier individuals, whereas lower endoscopy was preferred for relatively ill individuals. Nasogastric delivery may be less effective than colonoscopy, however, when taking into account cost, preparation, and potential risk this difference may not be clinically significant for patients with mild disease...

Background: Clostridium difficile infection (CDI) is a frequent complication in recipients of allogeneic hematopoietic stem cell transplantation (allo-HSCT), who receive intensive treatments that significantly disrupt the intestinal microbiota. In this study, we examined the microbiota composition of allo-HSCT recipients to identify bacterial colonizers that confer protection against CDI after engraftment. Methods: Feces collected from adult recipients allo-HSCT at engraftment were analyzed; 16S ribosomal RNA genes were sequenced and analyzed from each sample...

Exposure to microgravity leads to alterations in multiple systems, but microgravity-related changes in the gastrointestinal tract and its clinical significance have not been well studied. We used the hindlimb unloading (HU) mouse model to simulate a microgravity condition and investigated the changes in intestinal microbiota and colonic epithelial cells. Compared with ground controls (Ctrls), HU affected fecal microbiota composition with a profile that was characterized by the expansion of Firmicutes and decrease of Bacteroidetes The colon epithelium of HU mice showed decreased goblet cell numbers, reduced epithelial cell turnover, and decreased expression of genes that are involved in defense and inflammatory responses...

Fecal microbiota transplantation (FMT) is a very effective treatment for recurrent Clostridium difficile infection (CDI). Less is known about the application of FMT as a curative treatment of severe or complicated CDI. In this review, we present and discuss evidence supporting the curative use of FMT in severe or complicated CDI. We performed a literature search in PubMed and Embase for studies on the curative use of FMT in severe or complicated CDI. In addition, we describe a patient with severe CDI not responding to initial antibiotic treatment, who was successfully treated with curative FMT...

BACKGROUND: Faecal microbiota transplantation (FMT) has been investigated as a potential treatment for inflammatory bowel disease (IBD). We thus performed a systematic review and meta-analysis assessing the effectiveness and safety of FMT in IBD. METHODS: A systematic review was conducted until Jan 2017. Studies were excluded if patients had co-infection or data was pooled across disease subtypes (ulcerative colitis (UC), Crohn's disease (CD), pouchitis). Clinical remission was established as the primary outcome...

Non-alcoholic steatohepatitis (NASH) is an epidemic metabolic disease with limited therapeutic strategies. Cumulative data support the pivotal role of gut microbiota in NASH. Here, we investigated the hypothesis regarding whether fecal microbiota transplantation (FMT) is effective in attenuating high-fat diet (HFD)-induced steatohepatitis in mice. Mice were randomized into control, HFD and HFD + FMT groups. After an 8-week HFD, FMT treatment was initiated and carried out for 8 weeks. The gut microbiota structure, butyrate concentrations of the cecal content, liver pathology and intrahepatic lipid and cytokines were examined...

BACKGROUND: Fecal microbiota transplantation (FMT) is an effective treatment for recurrent Clostridium difficile infection and shows promise for treating other medical conditions associated with intestinal dysbioses. However, we lack a sufficient understanding of which microbial populations successfully colonize the recipient gut, and the widely used approaches to study the microbial ecology of FMT experiments fail to provide enough resolution to identify populations that are likely responsible for FMT-derived benefits...
