RESUMEN
BACKGROUND & AIMS: Fecal microbiota-based therapies include conventional fecal microbiota transplant and US Food and Drug Administration-approved therapies, fecal microbiota live-jslm and fecal microbiota spores live-brpk. The American Gastroenterological Association (AGA) developed this guideline to provide recommendations on the use of fecal microbiota-based therapies in adults with recurrent Clostridioides difficile infection; severe to fulminant C difficile infection; inflammatory bowel diseases, including pouchitis; and irritable bowel syndrome. METHODS: The guideline was developed using the GRADE (Grading of Recommendations, Assessment, Development, and Evaluation) framework to prioritize clinical questions, identify patient-centered outcomes, and conduct an evidence synthesis. The guideline panel used the Evidence-to-Decision framework to develop recommendations for the use of fecal microbiota-based therapies in the specified gastrointestinal conditions and provided implementation considerations for clinical practice. RESULTS: The guideline panel made 7 recommendations. In immunocompetent adults with recurrent C difficile infection, the AGA suggests select use of fecal microbiota-based therapies on completion of standard of care antibiotics to prevent recurrence. In mildly or moderately immunocompromised adults with recurrent C difficile infection, the AGA suggests select use of conventional fecal microbiota transplant. In severely immunocompromised adults, the AGA suggests against the use of any fecal microbiota-based therapies to prevent recurrent C difficile. In adults hospitalized with severe or fulminant C difficile not responding to standard of care antibiotics, the AGA suggests select use of conventional fecal microbiota transplant. The AGA suggests against the use of conventional fecal microbiota transplant as treatment for inflammatory bowel diseases or irritable bowel syndrome, except in the context of clinical trials. CONCLUSIONS: Fecal microbiota-based therapies are effective therapy to prevent recurrent C difficile in select patients. Conventional fecal microbiota transplant is an adjuvant treatment for select adults hospitalized with severe or fulminant C difficile infection not responding to standard of care antibiotics. Fecal microbiota transplant cannot yet be recommended in other gastrointestinal conditions.

ABSTRACT: Fecal microbiota transplantation (FMT) prevents recurrent Clostridioides difficile infections (rCDI) in patients with inflammatory bowel disease. Bezlotoxumab is also indicated to prevent rCDI. We assess the impact of FMT in combination with bezlotoxumab in patients with inflammatory bowel disease and rCDI. We conducted a multicenter randomized placebo-controlled trial. All received a single colonoscopic FMT. Patients were randomized 1:1 to receive bezlotoxumab or placebo. Sixty-one patients were enrolled (30 received treatment and 31 received placebo). Overall, 5 participants (8%) experienced a CDI recurrence; 4 in the treatment arm, 1 in the placebo arm (13% vs 3%, P = 0.15). There was no clear benefit to the combination approach compared with FMT alone.

INTRODUCTION: Clostridioides difficile infection (CDI) remains a global health challenge. Bezlotoxumab (BEZ) is a monoclonal antibody against C. difficile toxin B. Two randomized controlled trials (RCTs), MODIFY I and II, confirmed BEZ efficacy in preventing recurrent Clostridioides difficile infection (rCDI). However, there are safety concerns about its use in patients with a history of congestive heart failure. Observational studies have since been conducted, and it is important to explore the consistency of BEZ efficacy, cost-effectiveness, and its safety utilizing these real-world data. METHODS: We performed a systematic review and meta-analysis to pool the rate of rCDI in patients receiving BEZ and explore its efficacy and safety in preventing rCDI compared with control. We searched PubMed, EMBASE, Cochrane Library, and Google Scholar from inception through April 2023 for relevant RCTs or observational studies assessing BEZ in preventing rCDI. Single-arm studies describing experience with BEZ in preventing rCDI were also included for proportion meta-analysis. A proportion meta-analysis with a random-effects model was used to pool the rCDI rate with its corresponding 95% CI. In a meta-analysis of efficacy, we generated the relative risk (RR) to compare BEZ versus control in preventing rCDI. RESULTS: Thirteen studies including 2 RCTs and 11 observational studies totaling 2337 patients, of which 1472 received BEZ, were included in the analysis. Of the constituent studies, 5 (1734 patients) compared BEZ versus standard-of-care (SOC). Pooled rate of rCDI in patients receiving BEZ was 15.8% (95% CI: 14%-17.8%), and was 28.9% (95% CI: 24%-34.4%) in the SOC. BEZ significantly reduced rCDI risk compared with SOC [RR=0.57 (95% CI: 0.45-0.72, I2 =16%)]. There was no difference in the overall mortality or heart failure risk. Of the 9 included cost-effectiveness analyses, 8 demonstrated BEZ+SOC cost-effectiveness compared with SOC alone. DISCUSSION: Our meta-analysis comprising real-world data revealed lower rCDI in patients receiving BEZ and supported its efficacy and safety when added to SOC therapy. The results were consistent across various subgroups. Available cost-effectiveness analyses mostly support BEZ+SOC cost-effectiveness compared with SOC alone.

Poverty-exposed children with cancer are more likely to experience adverse outcomes. Supplemental Nutrition Assistance Program (SNAP) benefits improve food insecurity and child health outcomes, and could be used to mitigate disparities. We conducted a secondary analysis of parent-reported data collected in a frontline pediatric leukemia trial (NCT03020030) to assess SNAP eligibility (proxied by other means-tested program participation) and participation. At diagnosis, 105/287 families (37%) were SNAP-eligible, of whom 53 (50%) were SNAP participants. At 6 months, 104/257 families (41%) were SNAP-eligible, and 59 (57%) were SNAP participants. Interventions to increase benefits participation during childhood cancer treatment represent an immediate opportunity to reduce disparities.
RESUMEN
INTRODUCTION: Disparities in relapse and survival from high-risk neuroblastoma (HRNBL) persist among children from historically marginalized groups even in highly standardized clinical trial settings. Research in other cancers has identified differential treatment toxicity as one potential underlying mechanism. Whether racial and ethnic disparities in treatment-associated toxicity exist in HRNBL is poorly understood. METHODS: This is a retrospective study utilizing a previously assembled merged cohort of children with HRNBL on Children's Oncology Group (COG) post-consolidation immunotherapy trials ANBL0032 and ANBL0931 at Pediatric Health Information System (PHIS) centers from 2005 to 2014. Race and ethnicity were categorized to reflect historically marginalized populations as Hispanic, non-Hispanic Black (NHB), non-Hispanic other (NHO), and non-Hispanic White (NHW). Associations between race-ethnicity and intensive care unit (ICU)-level care utilization as a proxy for treatment-associated toxicity were examined with log binomial regression and summarized as risk ratio (RR) and corresponding 95% confidence interval (CI). RESULTS: The analytic cohort included 370 children. Overall, 88 (23.8%) patients required ICU-level care for a median of 3.0 days (interquartile range [IQR]: 1.0-6.5 days). Hispanic children had nearly three times the risk of ICU-level care (RR 3.1, 95% CI: 2.1-4.5; fully adjusted RR [aRR] 2.5, 95% CI: 1.6-3.7) compared to NHW children and the highest percentage of children requiring cardiovascular-driven ICU-level care. CONCLUSION: Children of Hispanic ethnicity with HRNBL receiving clinical trial-delivered therapy were more likely to experience ICU-level care compared to NHW children. These data suggest that further investigation of treatment-related toxicity as a modifiable mechanism underlying outcome disparities is warranted.

Myosin and myosin-binding protein C are exquisitely organized into giant filamentous macromolecular complexes within cardiac muscle sarcomeres, yet these proteins must be continually replaced to maintain contractile fidelity. The overall hypothesis that myosin filament structure is dynamic and allows for the stochastic replacement of individual components was tested in vivo, using a combination of mass spectrometry- and fluorescence-based proteomic techniques. Adult mice were fed a diet that marked all newly synthesized proteins with a stable isotope-labeled amino acid. The abundance of unlabeled and labeled proteins was quantified by high-resolution mass spectrometry over an 8-week period. The rates of change in the abundance of these proteins were well described by analytical models in which protein synthesis defined stoichiometry and protein degradation was governed by the stochastic selection of individual molecules. To test whether the whole myosin filaments or the individual components were selected for replacement, cardiac muscle was chemically skinned to remove the cellular membrane and myosin filaments were solubilized with ionic solutions. The composition of the filamentous and soluble fractions was quantified by mass spectrometry, and filament depolymerization was visualized by real-time fluorescence microscopy. Myosin molecules were preferentially extracted from ends of the filaments in the presence of the ionic solutions, and there was only a slight bias in the abundance of unlabeled molecules toward the innermost region on the myosin filaments. These data demonstrate for the first time that the newly synthesized myosin and myosin-binding protein C molecules are randomly mixed into preexisting thick filaments in vivo and the rate of mixing may not be equivalent along the length of the thick filament. These data collectively support a new model of cardiac myosin filament structure, with the filaments being dynamic macromolecular assemblies that allow for replacement of their components, rather than rigid bodies.

RATIONALE: Cardiac muscle cells are terminally differentiated after birth and must beat continually throughout one's lifetime. This mechanical process is driven by the sliding of actin-based thin filaments along myosin-based thick filaments, organized within sarcomeres. Despite costly energetic demand, the half-life of the proteins that comprise the cardiac thick filaments is â¼10 days, with individual molecules being replaced stochastically, by unknown mechanisms. OBJECTIVES: To allow for the stochastic replacement of molecules, we hypothesized that the structure of thick filaments must be highly dynamic in vivo. METHODS AND RESULTS: To test this hypothesis in adult mouse hearts, we replaced a fraction of the endogenous myosin regulatory light chain (RLC), a component of thick filaments, with GFP-labeled RLC by adeno-associated viral (AAV) transduction. The RLC-GFP was properly localized to the heads of the myosin molecules within thick filaments in ex vivo heart preparations and had no effect on heart size or actin filament siding in vitro. However, the localization of the RLC-GFP molecules was highly mobile, changing its position within the sarcomere on the minute timescale, when quantified by fluorescence recovery after photobleaching (FRAP) using multiphoton microscopy. Interestingly, RLC-GFP mobility was restricted to within the boundaries of single sarcomeres. When cardiomyocytes were lysed, the RLC-GFP remained strongly bound to myosin heavy chain, and the intact myosin molecules adopted a folded, compact configuration, when disassociated from the filaments at physiological ionic conditions. CONCLUSIONS: These data demonstrate that the structure of the thick filament is highly dynamic in the intact heart, with a rate of molecular exchange into and out of thick filaments that is â¼1500 times faster than that required for the replacement of molecules through protein synthesis or degradation.

Research and innovation around Clostridium difficile infection (CDI) has been a multidisciplinary endeavor since discovery of the organism in 1978. The field of gastroenterology has contributed to our understanding of CDI as a disease caused by disruptions in the gut microbiome and led to advances in therapeutic manipulation of gut microbiota, including fecal microbiota transplantation. The high incidence of CDI in patients with inflammatory bowel disease and treatment of the infection in this population have been of particular interest to gastroenterologists. The emergence of standardized, approved live biotherapeutic products for treatment of recurrent CDI is an inflection point in our management of this difficult clinical problem, and real-world performance of these therapies will inform optimal treatment algorithms.

BACKGROUND & AIMS: Fecal microbiota transplantation (FMT) emerged as rescue treatment for multiply recurrent Clostridioides difficile infections (rCDIs) nonresponsive to standard therapy. However, estimation of FMT efficacy varies among different protocols and formulations, while placebo-controlled clinical trials have excluded most rCDI patients because of medical comorbidities. This study aimed to determine the safety and effectiveness of capsule FMT (cap-FMT) and colonoscopy FMT (colo-FMT) for rCDI using standardized products in a large, multicenter, prospective, real-world cohort. METHODS: Clinical outcomes and adverse events after FMT performed for rCDI at 6 sites were captured in a prospective registry. FMT was performed using 1 of 2 standardized formulations of microbiota manufactured by the University of Minnesota Microbiota Therapeutics Program, freeze-dried/encapsulated or frozen-thawed/liquid. The FMT administration route was determined by the treating physician. The rCDI cure rate was assessed at 1 and 2 months. Safety data were collected within the first 72 hours and at 1 and 2 months. Logistic regression was used to investigate factors associated with FMT failure. RESULTS: A total of 301 FMTs were performed in 269 unique patients. Two-thirds were cap-FMT. CDI cure rates were 86% (95% CI, 82%-90%) at 1 month and 81% (95% CI, 75%-86%) at 2 months. There was no difference in the 1-month or 2-month cure rate between cap-FMT and colo-FMT. Cap-FMT recipients were older and less likely to be immunosuppressed or have inflammatory bowel disease. Patient factors of older age and hemodialysis were associated with FMT failure by 2 months on multivariate logistic regression. In addition, post-FMT antibiotic use was associated with FMT failure at 2 months. One serious adverse event was related to colonoscopy (aspiration pneumonia), otherwise no new safety signals were identified. CONCLUSIONS: Cap-FMT using freeze-dried capsules has a similar safety and effectiveness profile compared with colo-FMT, without the procedural risks of colonoscopy. Although highly effective overall, patient selection is a key factor to optimizing FMT success.

BACKGROUND: With rising time constraints, health care professionals increasingly depend on technology to provide health advice and teach patients how to manage chronic disease. The effectiveness of video-based tools in improving knowledge, health behaviors, disease severity, and health care use for patients with major chronic illnesses is not well understood. OBJECTIVE: The aim of this study was to assess the current literature regarding the efficacy of video-based educational tools for patients in improving process and outcome measures across several chronic illnesses. METHODS: A systematic review was conducted using CINAHL and PubMed with predefined search terms. The search included studies published through October 2021. The eligible studies were intervention studies of video-based self-management patient education for an adult patient population with the following chronic health conditions: asthma, chronic kidney disease, chronic obstructive pulmonary disease, chronic pain syndromes, diabetes, heart failure, HIV infection, hypertension, inflammatory bowel disease, and rheumatologic disorders. The eligible papers underwent full extraction of study characteristics, study design, sample demographics, and results. Bias was assessed with the Cochrane risk-of-bias tools. Summary statistics were synthesized in Stata SE (StataCorp LLC). Data reporting was conducted per the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) checklist. RESULTS: Of the 112 studies fully extracted, 59 (52.7%) were deemed eligible for inclusion in this review. The majority of the included papers were superiority randomized controlled trials (RCTs; 39/59, 66%), with fewer pre-post studies (13/59, 22%) and noninferiority RCTs (7/59, 12%). The most represented conditions of interest were obstructive lung disease (18/59, 31%), diabetes (11/59, 19%), and heart failure (9/59, 15%). The plurality (28/59, 47%) of video-based interventions only occurred once and occurred alongside adjunct interventions that included printed materials, in-person counseling, and interactive modules. The most frequently studied outcomes were disease severity, health behavior, and patient knowledge. Video-based tools were the most effective in improving patient knowledge (30/40, 75%). Approximately half reported health behavior (21/38, 56%) and patient self-efficacy (12/23, 52%) outcomes were improved by video-based tools, and a minority of health care use (11/28, 39%) and disease severity (23/69, 33%) outcomes were improved by video-based tools. In total, 48% (22/46) of the superiority and noninferiority RCTs and 54% (7/13) of the pre-post trials had moderate or high risk of bias. CONCLUSIONS: There is robust evidence that video-based tools can improve patient knowledge across several chronic illnesses. These tools less consistently improve disease severity and health care use outcomes. Additional study is needed to identify features that maximize the efficacy of video-based interventions for patients across the spectrum of digital competencies to ensure optimized and equitable patient education and outcomes.

BACKGROUND AND AIMS: Fecal microbiota transplantation (FMT) is a commonly used therapy for multiply recurrent Clostridioides difficile (mrCDI). By altering the gut microbiota, there is the potential for FMT to impact the risk for cardiometabolic, intestinal or immune-mediated conditions. Likewise, the microbiota disturbance associated with mrCDI could potentially lead to these conditions. We aimed to assess the associations of mrCDI and FMT with cardiometabolic, immune-mediated diseases, and irritable bowel syndrome. METHODS: This retrospective cohort study using a United States commercial claims database included persons diagnosed with CDI or undergoing FMT. We created 2 pairwise comparisons: mrCDI vs non-mrCDI, and non-mrCDI or mrCDI treated with FMT vs mrCDI without FMT. RESULTS: We found no significant association between mrCDI (vs non-mrCDI) and inflammatory bowel disease (adjusted hazard ratio (aHR) = 1.65; 95% confidence interval, 0.67-4.04), rheumatoid arthritis (HR = 0.86; 0.47-1.56), psoriasis (HR = 0.72; 0.23-2.27), diabetes (aHR = 0.97; 0.67-1.40), hypertension (aHR = 1.05; 0.76-1.44), myocardial infarction (aHR = 0.82; 0.63-1.06), stroke (aHR = 0.83; 0.62-1.12), or irritable bowel syndrome (HR = 0.94; 0.61-1.45). Similarly, we found no association of CDI with FMT (vs mrCDI without FMT) and diabetes (aHR = 0.92; 0.27-3.11), hypertension (aHR = 1.41; 0.64-3.15), stroke (aHR = 1.27; 0.69-2.34) or inflammatory bowel syndrome (aHR = 0.80; 0.26-2.46). However, the incidence of myocardial infarction was increased following FMT (aHR = 1.68; 1.01-2.81). CONCLUSION: Relative to those with CDI, persons with mrCDI do not appear to be intrinsically at higher risk of cardiometabolic, immune-mediated diseases, or irritable bowel syndrome. However, those who underwent FMT for CDI had a higher incidence of myocardial infarction. Future studies should assess this association to assess reproducibility.

BACKGROUND & AIMS: Fecal microbiota transplantation (FMT) is used commonly for treatment of Clostridioides difficile infections (CDIs), although prospective safety data are limited and real-world FMT practice and outcomes are not well described. The FMT National Registry was designed to assess FMT methods and both safety and effectiveness outcomes from North American FMT providers. METHODS: Patients undergoing FMT in clinical practices across North America were eligible. Participating investigators enter de-identified data into an online platform, including FMT protocol, baseline patient characteristics, CDI cure and recurrence, and short and long-term safety outcomes. RESULTS: Of the first 259 participants enrolled at 20 sites, 222 had completed short-term follow-up at 1 month and 123 had follow-up to 6 months; 171 (66%) were female. All FMTs were done for CDI and 249 (96%) used an unknown donor (eg, stool bank). One-month cure occurred in 200 patients (90%); of these, 197 (98%) received only 1 FMT. Among 112 patients with initial cure who were followed to 6 months, 4 (4%) had CDI recurrence. Severe symptoms reported within 1-month of FMT included diarrhea (n = 5 [2%]) and abdominal pain (n = 4 [2%]); 3 patients (1%) had hospitalizations possibly related to FMT. At 6 months, new diagnoses of irritable bowel syndrome were made in 2 patients (1%) and inflammatory bowel disease in 2 patients (1%). CONCLUSIONS: This prospective real-world study demonstrated high effectiveness of FMT for CDI with a good safety profile. Assessment of new conditions at long-term follow-up is planned as this registry grows and will be important for determining the full safety profile of FMT.

OBJECTIVE: Prior to the Continuous Monitoring and Control of Hypoglycaemia (COACH) study described herein, no study had been powered to evaluate the impact of non-adjunctive RT-CGM use on the rate of debilitating moderate or severe hypoglycaemic events. RESEARCH DESIGN AND METHODS: In this 12-month observational study, adults with insulin-requiring diabetes who were new to RT-CGM participated in a 6-month control phase where insulin dosing decisions were based on self monitoring of blood glucose values, followed by a 6-month phase where decisions were based on RT-CGM data (i.e. non-adjunctive RT-CGM use); recommendations for RT-CGM use were made according to sites' usual care. The primary outcome was change in debilitating moderate (requiring second-party assistance) and severe (resulting in seizures or loss of consciousness) hypoglycaemic event frequency. Secondary outcomes included changes in HbA1c and diabetic ketoacidosis (DKA) frequency. RESULTS: A total of 519 participants with mean (SD) age 50.3 (16.1) years and baseline HbA1c 8.0% (1.4%) completed the study, of whom 32.8% had impaired hypoglycaemia awareness and 33.5% had type 2 diabetes (T2D). The mean (SE) per-patient frequency of hypoglycaemic events decreased by 63% from 0.08 (0.016) during the SMBG phase to 0.03 (0.010) during the RT-CGM phase (p = 0.005). HbA1c decreased during the RT-CGM phase both for participants with type 1 diabetes (T1D) and T2D and there was a trend towards larger reductions among individuals with higher baseline HbA1c. CONCLUSIONS: Among adults with insulin-requiring diabetes, non-adjunctive use of RT-CGM data is safe, resulting in significantly fewer debilitating hypoglycaemic events than management using SMBG.

Clostridioides difficile infection occurs when the bacterium produces toxin that causes diarrhea and inflammation of the colon. These guidelines indicate the preferred approach to the management of adults with C. difficile infection and represent the official practice recommendations of the American College of Gastroenterology. The scientific evidence for these guidelines was evaluated using the Grading of Recommendations Assessment, Development, and Evaluation process. In instances where the evidence was not appropriate for Grading of Recommendations Assessment, Development, and Evaluation but there was consensus of significant clinical merit, key concept statements were developed using expert consensus. These guidelines are meant to be broadly applicable and should be viewed as the preferred, but not the only, approach to clinical scenarios.

BACKGROUND: Many childhood cancersurvivors experience at least one late effect of treatment, and both late effects and persistent cancer-related worry can negatively impact quality of life in survivorship. Little is known about the prevalence or impact of parental worry about late effects early in treatment. This study evaluated parental perceived likelihood, impact, and worry about late effects of childhood cancer. PROCEDURE: We surveyed 96 parents of pediatric cancer patients at Dana-Farber/Boston Children's Cancer and Blood Disorders Center within a year of diagnosis. Parents were asked about their experiences with late effects communication, general worry about late effects, and specific late effect worries. RESULTS: Most (96%) parents valued information about late effects, and 93% considered late effects in their treatment decision-making. Yet, 24% could not recall receiving any information about late effects, and only 51% felt well prepared for potential late effects. Though only 20% of parents considered their child at high risk of experiencing late effects, 61% were extremely/very worried about late effects. Those who felt their child was at high risk of experiencing late effects were more likely to worry (OR = 4.7, P = 0.02). CONCLUSIONS: Many parents feel inadequately informed about late effects of cancer treatment, and only one-fifth of parents consider late effects to be likely for their child. However, a majority of parents worry about late effects, including ones they think their child is unlikely to experience. Although some worry is anticipated, disproportionate worry may be mitigated by addressing both educational shortfalls and emotional concerns.

BACKGROUND AND AIM: Fulminant Clostridioides difficile infections (FCDI) account for 8% of cases and substantial healthcare burden. Fecal microbiota transplantation is recommended for recurrent CDI, but emerging data support use for FCDI. We aimed to assess the cost-effectiveness of a sequential fecal microbiota transplantation (sFMT) protocol for FCDI compared with current standard therapy. METHODS: A Markov model simulated patients with FCDI in a 1-year time horizon. The treatment algorithm for up to three sFMTs, clinical probabilities, and direct costs were used from published sources. Outcomes were quality-adjusted life years (QALYs) and costs. The healthcare sector perspective was used with a willingness-to-pay threshold of $100 000 per QALY. RESULTS: Sequential fecal microbiota transplantation (FMT) for FCDI was associated with lower overall cost ($28 309 vs $33 980) and higher QALY (0.765 vs 0.686) compared with standard therapy. sFMT is cost-effective in 100% of iterations. sFMT remained cost-effective at cure rates > 44.8% for the first FMT and at stool preparation cost < $6944 per instillation. We find a wide range of efficacies for the first versus second FMT at which sFMT is still preferred. Value of information analysis estimates the expected value of perfect information to be low at $1.89 per person, quantified with net monetary benefit. CONCLUSIONS: An sFMT strategy strongly dominates standard therapy, with lower cost and higher QALY. Sensitivity analysis demonstrates benefit even if FMT cure rates are lower than expected and when multiple FMTs are required. FMT material in 2020 was priced at $1695 per treatment but remains cost-effective at a much higher cost.

BACKGROUND: Fecal microbiota transplantation (FMT) is a highly effective therapy for recurrent Clostridioides difficile infection (CDI); however, a small percentage of patients fail to achieve cure even after two FMTs. This high-risk cohort remains poorly understood. METHODS: We performed a multicenter, multinational retrospective review of patients that underwent at least one FMT for a CDI indication at four academic FMT referrals. Patients' data including CDI, FMT, and FMT variables were assessed. The primary outcome was FMT failure after a second FMT defined as persistent diarrhea and positive laboratory test for C. difficile (PCR or toxin) despite a second FMT within 8 weeks of the first FMT. A multivariable logistic regression model was performed to determine predictors of second FMT failure. RESULTS: A total of 540 patients received at least one FMT during the study period, of which 432 patients had success following the first FMT, 108 had documented failure (25%). Among those who failed the first FMT, 63 patients received a second FMT, of which 36 achieved cure, and 24 had documented failure after the second FMT. Patients that failed the first FMT but did not receive a second FMT and those lost to follow-up were excluded leaving 492 patients included in the analysis. The second FMT failure rate was 4.8% (24/492). Risk factors for second FMT failure identified by multivariable logistic regression included: inpatient status (OR 7.01, 95% CI: 2.37-20.78), the presence of pseudomembranes (OR 3.53, 95% CI: 1.1-11.33), and immunocompromised state (OR 3.56, 95% CI: 1.45-8.72) at the time of first FMT. CONCLUSION: This study identifies clinically relevant risk factors predictive of failing a second FMT. Clinicians can use these variables to help identify high-risk patients and provide a better-informed consent regarding the possibility of needing multiple FMTs.

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 Clostridioides difficile infection. In the time of the pandemic, FMT centres and stool banks are required to adopt a workflow that continues to ensure reliable patient access to FMT while maintaining safety and quality of procedures. In this position paper, based on the best available evidence, worldwide FMT experts provide guidance on issues relating to the impact of COVID-19 on FMT, including patient selection, donor recruitment and selection, stool manufacturing, FMT procedures, patient follow-up and research activities.

OBJECTIVE: Faecal microbiota transplantation (FMT) has proved to be an extremely effective treatment for recurrent Clostridioides difficile infection, and there is interest in its potential application in other gastrointestinal and systemic diseases. However, the recent death and episode of septicaemia following FMT highlights the need for further appraisal and guidelines on donor evaluation, production standards, treatment facilities and acceptable clinical indications. DESIGN: For these consensus statements, a 24-member multidisciplinary working group voted online and then convened in-person, using a modified Delphi approach to formulate and refine a series of recommendations based on best evidence and expert opinion. Invitations to participate were directed to Australian experts, with an international delegate assisting the development. The following issues regarding the use of FMT in clinical practice were addressed: donor selection and screening, clinical indications, requirements of FMT centres and future directions. Evidence was rated using the GRADE (Grading of Recommendations Assessment, Development and Evaluation) system. RESULTS: Consensus was reached on 27 statements to provide guidance on best practice in FMT. These include: (1) minimum standards for donor screening with recommended clinical selection criteria, blood and stool testing; (2) accepted routes of administration; (3) clinical indications; (4) minimum standards for FMT production and requirements for treatment facilities acknowledging distinction between single-site centres (eg, hospital-based) and stool banks; and (5) recommendations on future research and product development. CONCLUSIONS: These FMT consensus statements provide comprehensive recommendations around the production and use of FMT in clinical practice with relevance to clinicians, researchers and policy makers.
