    (Oxford University Press, 2021-07-23) Song, Yi Nong; Yang, David Yi; Veldhuyzen van Zanten, Sander; Wong, Karen; McArthur, Eric; Zhao Song, Claire; Ianiro, Gianluca; Cammarota, Giovanni; Kelly, Colleen; Fischer, Monika; Russell, Lindsey; Kao, Dina; Medicine, School of Medicine
    Background: Severe or fulminant Clostridioides difficile infection (SFCDI) is associated with significant morbidity and mortality. Emerging evidence suggests fecal microbiota transplant (FMT) may be a promising therapy for SFCDI. Aim: This systematic review determines the safety and efficacy of FMT in medically refractory SFCDI. Methods: A systematic search of the literature was conducted using PubMed (1965 to 2020), Web of Science (1900 to 20), EMBASE (1974 to 2020), and Cochrane Review (1945 to 2020). Quality appraisal by NIH Study Quality Assessment tools, and data extraction were performed by two teams of independent researchers. The primary outcome was resolution of SFCDI 4 weeks after the final FMT. Pooled resolution rates were calculated using generalized linear mixed models estimates. Results: Two hundred and forty patients from 10 studies (8 case series, 1 case-control and 1 randomized study) were included with 209 individual patient-level data. FMT resulted in resolution of SFCDI within 4 weeks in 211/240 individuals for a pooled estimate of 88% (95% confidence interval [CI]: 0.83 to 0.91). The mean number of FMT required was 1.6 for severe and 2.0 for fulminant CDI resolution. The pooled proportional estimates for patients requiring CDI-directed antimicrobials after FMT was 50% (95% CI: 0.06 to 0.94) for severe CDI and 67.0% (95% CI: 0.30 to 0.91) for fulminant CDI. Serious adverse event rates were low. Conclusion: FMT appears effective in treating SFCDI patients with low adverse events, but requires multiple treatments with a significant proportion of patients requiring additional anti-CDI antibiotics to achieve resolution. The optimal route of FMT delivery remains unknown. The presence of pseudomembranous colitis may guide additional FMT or anti-CDI antibiotic treatment.

    Fecal Microbiota Transplantation Is Safe and Effective in Patients With Clostridioides difficile Infection and Cirrhosis
    (Elsevier, 2020) Cheng, Yao-Wen; Alhaffar, Dana; Saha, Srishti; Khanna, Sahil; Bohm, Matthew; Phelps, Emmalee; Ghabril, Marwan; Orman, Eric; Sashidhar, Sagi; Rogers, Nicholas; Xu, Huiping; Khoruts, Alexander; Vaughn, Byron; Kao, Dina; Wong, Karen; Cammarota, Giovanni; Ianiro, Gianluca; Dhere, Tanvi; Kraft, Colleen S.; Mehta, Nirja; Woodworth, Michael H.; Allegretti, Jessica R.; Nativ, Lotem; Marcus, Jenna; El-Nachef, Najwa; Fischer, Monika; Medicine, School of Medicine
    Background & Aims Clostridioides difficile infection (CDI) harms a large proportion of patients with cirrhosis. Fecal microbiota transplantation (FMT) is recommended for recurrent CDI, but its effects in patients with cirrhosis have not been established. We performed a multicenter observational study to evaluate the efficacy and safety of FMT for CDI in patients with cirrhosis. Methods We performed a retrospective study of 63 adults with cirrhosis (median model for end-stage liver disease score, 14.5; 24 patients with decompensated cirrhosis) who underwent FMT for CDI from January 2012 through November 2018 at 8 academic centers in the United States, Canada, and Italy. We collected data on patient demographics and characteristics of cirrhosis, CDI, and FMT from medical records and compared differences among patients with different severities of cirrhosis, and FMT successes vs failures at the 8-week follow-up evaluation. We also obtained data on adverse events (AEs) and severe AEs within 12 weeks of FMT. Results Patients underwent FMT for recurrent CDI (55 of 63; 87.3%), severe CDI (6 of 63; 9.5%), or fulminant CDI (2 of 63; 3.2%) primarily via colonoscopy (59 of 63; 93.7%) as outpatients (47 of 63; 76.8%). FMT success was achieved for 54 patients (85.7%). Among FMT failures, a higher proportion used non-CDI antibiotics at the time of FMT (44.4% vs 5.6%; P < .001), had Child–Pugh scores of B or C (100% vs 37.7%; P < .001), used probiotics (77.8% vs 24.1%; P = .003), had pseudomembranes (22.2% vs 0; P = .018), and underwent FMT as inpatients (45.5% vs 19%; P = .039), compared with FMT successes. In multivariable analysis, use of non-CDI antibiotics at the time of FMT (odds ratio, 17.43; 95% CI, 2.00–152.03; P = .01) and use of probiotics (odds ratio, 11.9; 95% CI, 1.81–78.3; P = .01) were associated with a greater risk of FMT failure. FMT-related AEs occurred in 33.3% of patients (21 of 63)—most were self-limited abdominal cramps or diarrhea. There were only 5 severe AEs that possibly were related to FMT; none involved infection or death. Conclusions In a retrospective study, we found FMT to be safe and effective for the treatment of CDI in patients with cirrhosis.

    Reorganisation of faecal microbiota transplant services during the COVID-19 pandemic
    (BMJ Publishing Group, 2020-07-03) Ianiro, Gianluca; Mullish, Benjamin H.; Kelly, Colleen R.; Kassam, Zain; Kuijper, Ed J.; Ng, Siew C.; Iqbal, Tariq H.; Allegretti, Jessica R.; Bibbò, Stefano; Sokol, Harry; Zhang, Faming; Fischer, Monika; Costello, Samuel Paul; Keller, Josbert J.; Masucci, Luca; Prehn, Joffrey van; Quaranta, Gianluca; Quraishi, Mohammed Nabil; Segal, Jonathan; Kao, Dina; Satokari, Reetta; Sanguinetti, Maurizio; Tilg, Herbert; Gasbarrini, Antonio; Cammarota, Giovanni; Medicine, School of Medicine
    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.
