The presence of Clostridioides difficile in faeces before and after faecal microbiota transplantation and its relation with recurrent C. difficile infection and the gut microbiota in a Dutch cohort.

Objectives: To study the presence of Clostridioides difficile in faeces of patients with recurrent C. difficile infection (rCDI) before and after faecal microbiota transplantation (FMT) and to identify risk factors for faecal C. difficile and CDI recurrence.

Gut microbiota strain richness is species specific and affects engraftment.

Despite the fundamental role of bacterial strain variation in gut microbiota function, the number of unique strains of a species that can stably colonize the human intestine is still unknown for almost all species. Here we determine the strain richness (SR) of common gut species using thousands of sequenced bacterial isolates with paired metagenomes. We show that SR varies across species, is transferable by faecal microbiota transplantation, and is uniquely low in the gut compared with soil and lake environments.

Dynamics of Gut Microbiota after Fecal Microbiota Transplantation in Ulcerative Colitis: Success Linked to Control of Prevotellaceae.

Background: Fecal microbiota transplantation (FMT) is an experimental treatment for ulcerative colitis (UC). We aimed to study microbial families associated with FMT treatment success.

Methods: We analyzed stools from 24 UC patients treated with four FMTs weekly after randomization for pretreatment during three weeks with budesonide (n = 12) or placebo (n = 12).

Faecal Microbiota Transplantation Engraftment After Budesonide or Placebo in Patients With Active Ulcerative Colitis Using Pre-selected Donors: A Randomized Pilot Study.

Background: Faecal microbiota transplantation [FMT] shows some efficacy in treating patients with ulcerative colitis [UC], although variability has been observed among donors and treatment regimens. We investigated the effect of FMT using rationally selected donors after pretreatment with budesonide or placebo in active UC.

Methods: Patients ≥18 years old with mild to moderate active UC were randomly assigned to 3 weeks of budesonide [9 mg] or placebo followed by 4-weekly infusions of a donor faeces suspension.

Long-term beneficial effect of faecal microbiota transplantation on colonisation of multidrug-resistant bacteria and resistome abundance in patients with recurrent Clostridioides difficile infection.

Background: Multidrug-resistant (MDR) bacteria are a growing global threat, especially in healthcare facilities. Faecal microbiota transplantation (FMT) is an effective prevention strategy for recurrences of Clostridioides difficile infections and can also be useful for other microbiota-related diseases.

Methods: We study the effect of FMT in patients with multiple recurrent C.

Fecal microbiota transplantation for Parkinson's disease using levodopa - carbidopa intestinal gel percutaneous endoscopic gastro-jejeunal tube.

We report a patient with a 5-year diagnosis of akinetic-rigid Parkinson's disease under treatment with Levodopa-Carbidopa Intestinal Gel therapy through a PEG-J tube due to motor complications, in which, in the context of a clinical study, we successfully and safely administered fecal microbiota transplant through a PEG-J.

[100 years Peutz-Jeghers syndrome].

In 2021 it was 100 years since drPeutz published his case report titled: 'a very remarkable case of familial polyposis of mucous membranes of intestinal tract and nasopharynx accompanied by peculiar pigmentations of skin and mucous membrane'. This is the first description of the Peutz-Jeghers syndrome, which is named after him. Like Peutz already suggested a century ago, we know now that this is a genetic disorder (autosomal dominant) caused by mutations in the STK11 gene.

How to prepare stool banks for an appropriate response to the ongoing COVID-19 pandemic: Experiences in the Netherlands and a retrospective comparative cohort study for faecal microbiota transplantation.

Background: Faecal microbiota transplantation (FMT) is an efficacious treatment for patients with recurrent Clostridioides difficile infections (rCDI). Stool banks facilitate FMT by providing screened faecal suspensions from highly selected healthy donors. Due to the ongoing coronavirus disease 2019 (COVID-19) pandemic and the potential risk of SARS coronavirus-2 (SARS-CoV-2) transmission via FMT, many stool banks were forced to temporarily halt and adjust donor activities.

The use of Faecal Microbiota Transplantation (FMT) in Europe: A Europe-wide survey.

Background: Faecal microbiota transplantation (FMT) is an emerging treatment modality, but its current clinical use and organisation are unknown. We aimed to describe the clinical use, conduct, and potential for FMT in Europe.

Methods: We invited all hospital-based FMT centres within the European Council member states to answer a web-based questionnaire covering their clinical activities, organisation, and regulation of FMT in 2019.

Prognostic factors for severe and recurrent Clostridioides difficile infection: a systematic review.

Objectives: Clostridioides difficile infection (CDI), its subsequent recurrences (rCDIs), and severe CDI (sCDI) provide a significant burden for both patients and the healthcare system. Identifying patients diagnosed with initial CDI who are at increased risk of developing sCDI/rCDI could lead to more cost-effective therapeutic choices. In this systematic review we aimed to identify clinical prognostic factors associated with an increased risk of developing sCDI or rCDI.

Fecal Microbiota Transplantation Influences Procarcinogenic Escherichia coli in Recipient Recurrent Clostridioides difficile Patients.

Background & Aims: Patients with multiple recurrent Clostridioides difficile infection (rCDI) have a disturbed gut microbiota that can be restored by fecal microbiota transplantation (FMT). Despite extensive screening, healthy feces donors may carry bacteria in their intestinal tract that could have long-term health effects, such as potentially procarcinogenic polyketide synthase-positive (pks) Escherichia coli. Here, we aim to determine whether the pks abundance and persistence of pksE coli is influenced by pks status of the donor feces.

Periodic screening of donor faeces with a quarantine period to prevent transmission of multidrug-resistant organisms during faecal microbiota transplantation: a retrospective cohort study.

Background: On June 13, 2019, the US Food and Drug Administration issued a warning after transfer of faeces containing an extended-spectrum β-lactamase (ESBL)-producing Escherichia coli by faecal microbiota transplantation led to bacteraemia in two immunocompromised patients. Consequently, we evaluated the effectiveness of the faeces donor-screening protocol of the Netherlands Donor Faeces Bank, which consists of screening of donors for multidrug-resistant organisms every 3 months, combined with additional screening on indication (eg, after travelling abroad) and application of a quarantine period for all faecal suspensions delivered within those 3 months.

Methods: We did a retrospective cohort study of data collected between Jan 1, 2015, and Oct 14, 2019, on the multidrug-resistant organism testing results of donor faeces.

A standardised model for stool banking for faecal microbiota transplantation: a consensus report from a multidisciplinary UEG working group.

Background: Faecal microbiota transplantation is an emerging therapeutic option, particularly for the treatment of recurrent Clostridioides difficile infection. Stool banks that organise recruitment and screening of faeces donors are being embedded within the regulatory frameworks described in the European Union Tissue and Cells Directive and the technical guide to the quality and safety of tissue and cells for human application, published by the European Council.

Objective: Several European and international consensus statements concerning faecal microbiota transplantation have been issued.

Faecal microbiota transplantation for infection: Four years' experience of the Netherlands Donor Feces Bank.

Background: The Netherlands Donor Feces Bank provides standardized ready-to-use donor faecal suspensions for faecal microbiota transplantation treatment of patients with recurrent infection.

Objective: The purpose of this study was evaluation of safety, feasibility and outcome of faecal microbiota transplantation facilitated by a national stool bank.

Methods: The methods used included: observational cohort study of donors and recipients of faecal suspensions; assessment of donor screening and patient selection performed by an expert panel of medical microbiologists, gastroenterologists and infectious disease specialists; and patient outcome evaluated at different timepoints after faecal microbiota transplantation.

Reorganisation of faecal microbiota transplant services during the COVID-19 pandemic.

The COVID-19 pandemic has led to an exponential increase in SARS-CoV-2 infections and associated deaths, and represents a significant challenge to healthcare professionals and facilities. Individual countries have taken several prevention and containment actions to control the spread of infection, including measures to guarantee safety of both healthcare professionals and patients who are at increased risk of infection from COVID-19. Faecal microbiota transplantation (FMT) has a well-established role in the treatment of infection.

Fecal Microbiota Transplantation in Neurological Disorders.

Several studies suggested an important role of the gut microbiota in the pathophysiology of neurological disorders, implying that alteration of the gut microbiota might serve as a treatment strategy. Fecal microbiota transplantation (FMT) is currently the most effective gut microbiota intervention and an accepted treatment for recurrent infections. To evaluate indications of FMT for patients with neurological disorders, we summarized the available literature on FMT.

Human Transmission of Blastocystis by Fecal Microbiota Transplantation Without Development of Gastrointestinal Symptoms in Recipients.

Background: Patients with multiple recurrent Clostridioides difficile infections (rCDI) are treated with fecal microbiota transplantation (FMT), using feces provided by healthy donors. Blastocystis colonization of donors is considered an exclusion criterion, whereas its pathogenicity is still under debate.

Methods: The introduction of molecular screening for Blastocystis sp.

International consensus conference on stool banking for faecal microbiota transplantation in clinical practice.

Although faecal microbiota transplantation (FMT) has a well-established role in the treatment of recurrent infection (CDI), its widespread dissemination is limited by several obstacles, including lack of dedicated centres, difficulties with donor recruitment and complexities related to regulation and safety monitoring. Given the considerable burden of CDI on global healthcare systems, FMT should be widely available to most centres.Stool banks may guarantee reliable, timely and equitable access to FMT for patients and a traceable workflow that ensures safety and quality of procedures.

[Chronic diarrhoea in daily practice; article for education and training purposes].

Chronic diarrhoea occurs in patients of all ages and is a very common reason for patient visits to a general practitioner or medical specialist. The differential diagnosis of chronic diarrhoea is extensive and identification of the underlying cause can be challenging. In this article we answer 12 topical questions concerning the management of chronic diarrhoea in practice.

Complications, effectiveness, and long term follow-up of fecal microbiota transfer by nasoduodenal tube for treatment of recurrent infection.

Background: Fecal microbiota transfer (FMT) is an effective treatment for recurrent infection (CDI), but data on procedure-related complications and long-term outcome are scarce.

Methods: All patients treated with FMT for recurrent CDI at the Academic Medical Center between July 2010 and January 2016 were included. FMT was performed according to the FECAL trial protocol: administration of fresh donor feces (related or unrelated donor) through a duodenal tube after pre-treatment with vancomycin and bowel lavage.
