Fecal microbiota transplantation (FMT), which has been established as the standard treatment for recurrent <i>Clostroides</i> difficile infection, may also play a role in the management of other diseases associated with dysbiosis of the gut microbiota. To ensure efficacy and safety of FMT, an appropriate donor screening process is required. The main purpose of donor screening is to check for infectious diseases that could be transmitted to the recipient. The screening process involves a medical history questionnaire, and blood and stool testing. Several randomized clinical trials and large case series on FMT reported no, or few, adverse events related to infection by following this donor screening process. However, there is still concern over the transmission of antibiotic-resistant bacteria. In addition, a low donor acceptance rate due to rigorous screening makes donor recruitment difficult, and also imposes a significant cost burden. A consensus on the most crucial elements of donor screening is needed for wide application of FMT.

In this review, we discuss stool donor screening considerations to mitigate potential risks of pathogen transmission through fecal microbiota transplant (FMT) in solid organ transplant (SOT) recipients. SOT recipients have a higher risk for Clostridioides difficile infection (CDI) and are more likely to have severe CDI. FMT has been shown to be a valuable tool in the treatment of recurrent CDI (RCDI), however guidelines for screening for opportunistic infections transmitted through FMT are underdeveloped. We review reported adverse effects of FMT as they pertain to an immunocompromised population and discuss current understanding and recommendations for screening found in the literature while noting gaps in research. We conclude that while FMT is being performed in the SOT population, typically with positive results, there remain many unanswered questions which may have major safety implications and warrant further study.

Abstract Background Knowledge of the impact of the gut microbiome on conditions other than Clostridium difficile infection has been rapidly increasing, and the potential usefulness of fecal microbiota transplantation (FMT) in these indications is being explored. The need to exclude donors with an increased risk of these diseases has left uncertainties regarding the cost and feasibility of donor screening. The aim of this study was to compare our experience to other donor-screening programs and report the costs associated with establishing a donor-screening program, for the treatment of metabolic syndrome-related conditions. Methods Forty-six potential donors (PDs) had their medical histories and physical examinations undertaken by a physician. Blood, stool, and urine were screened for 31 viral, bacterial, fungal, and protozoan agents in addition to biochemical characteristics. The price of advertising, doctor’s visits and diagnostic tests were calculated to determine the cost of finding a donor. Results Of the PDs screened, 5 of 46 passed the history, examination, blood, stool, and urine tests. The most common reasons for exclusion included a body mass index &gt;25 or the detection of Blastocystis hominis, Dientamoeba fragilis, or Helicobacter pylori. Four of five eligible donors had subsequent travel or illness that contraindicated donation, so only 1 of 46 PDs was suitable. The total cost for finding a single suitable donor was $15190 US dollars. This screening was performed in Canada, and costs in the United States would be substantially higher. Conclusions New potential therapeutic uses for FMT have created a demand for stricter exclusion criteria for donors. This study illustrates that screening many individuals to find a donor and the subsequent associated costs may make central processing and shipment a more reasonable alternative.

Review question / Objective: Western pacific and South-east Asian region have its own lifestyle and dietary habits, for an example, the prevalence of parasites and the MDR pathogens are different compared to the European region where most consensus documents have been disseminated. Hence, current investigation is being carried out in view of appraising contemporary methods that have been used internationally and to propose rigorous donor screening methods appropriate for the regional requirement. Information sources: EMBASE and MEDLINE through PubMed and WEB of SCIENCE. Additionally, we have reviewed all international consensus documents and local guidelines published in English.

Objectives: Fecal microbiota transplantation (FMT) is a recommended therapy for recurrent Clostridioides difficile infection and is being investigated as a potential therapy for dozens of microbiome-mediated indications. Stool banks centralize FMT donor screening and FMT material preparation with the goal of improving the safety, quality, convenience, and accessibility of FMT material. Although there are published consensuses on donor screening guidelines, there are few reports about the implementation of those guidelines in functioning stool banks. Methods: To help inform consensus standards with data gathered from real-world settings and, in turn, to improve patient care, here we describe the general methodology used in 2018 by OpenBiome, a large stool bank, and its outputs in that year. Results: In 2018, the stool bank received 7,536 stool donations from 210 donors, a daily average of 20.6 donations, and processed 4,271 of those donations into FMT preparations. The median time a screened and enrolled stool donor actively donated stool was 5.8 months. The median time between the manufacture of an FMT preparation and its shipment to a hospital or physician was 8.9 months. Half of the stool bank's partner hospitals and physicians ordered an average of 0.75 or fewer FMT preparations per month. Conclusions: Further knowledge sharing should help inform refinements of stool banking guidelines and best practices.

ABSTRACTThe potential for transmission of SARS-CoV-2 shed in stool via fecal microbiota transplantation is not yet known, and the effectiveness of various testing strategies to prevent FMT-based transmission has also not yet been quantified. Here we use a mathematical model to simulate the utility of different testing strategies.

Despite high efficacy rates, significant costs and logistical challenges associated with procuring stool from healthy donors for fecal microbiota transplantation (FMT) have presented barriers to broader institutional adoption and limited the availability of this life-saving treatment. Published outcomes for donor screening programs report donor deferral rates between 90% and 96%. Due to the paucity of FMT donor screening data, a secondary analysis on a cohort of previously screened donors (n = 7,968) was conducted to provide a synopsis of the observed trends and rationales for prospective stool donor deferrals. Upon completion of the evaluation, 1.7% of prospective donors (n = 134) qualified for stool donation. Over 50% of donors who completed the online pre-screen were deferred, primarily for a body mass index of 30 kg/m2 or greater (n = 1,516, 37.0%), logistics (n = 841, 20.5%), and travel history (n = 638, 15.5%). Despite pre-screening, 569 donors (72.8%) who completed the in-person clinical assessment were ultimately deferred due primarily to potentially microbiome-mediated diseases (n = 187, 32.9%). A notably small portion of donors (n = 46, 25.6%) were deferred during the laboratory assessment process suggesting the clinical assessment was effective at deferring donors at higher risk for transmissible diseases. Donors lost to follow-up throughout the screening process presented a significant challenge and contributed to a notable (n = 3,117; 39.1%) portion of donor attrition. Findings were used to support recommendations for improving prospective stool donor screening programs and to provide suggestions for future research.
