Abstract
Clostridioides difficile (formerly Clostridium difficile) has been regarded as an 'urgent threat' and a significant global health problem, as life-threatening diarrhoea and refractory recurrence are common in patients with C. difficile infection (CDI). Unfortunately, the available anti-CDI drugs are limited. Recent guidelines recommend fidaxomicin and vancomycin as first-line drugs to treat CDI, bezlotoxumab to prevent recurrence, and faecal microbiota transplantation for rescue treatment. Currently, researchers are investigating therapeutic antibacterial drugs (e.g. teicoplanin, ridinilazole, ibezapolstat, surotomycin, cadazolid, and LFF571), preventive medications against recurrence (e.g. Rebyota, Vowst, VP20621, VE303, RBX7455, and MET-2), primary prevention strategies (e.g. vaccine, ribaxamase, and DAV132) and other anti-CDI medications in the preclinical stage (e.g. Raja 42, Myxopyronin B, and bacteriophage). This narrative review summarises current medications, including newly marketed drugs and products in development against CDI, to help clinicians treat CDI appropriately and to call for more research on innovation.

Abstract
SUMMARYGiven the importance of gut microbial homeostasis in maintaining health, there has been considerable interest in developing innovative therapeutic strategies for restoring gut microbiota. One such approach, fecal microbiota transplantation (FMT), is the main "whole gut microbiome replacement" strategy and has been integrated into clinical practice guidelines for treating recurrent Clostridioides difficile infection (rCDI). Furthermore, the potential application of FMT in other indications such as inflammatory bowel disease (IBD), metabolic syndrome, and solid tumor malignancies is an area of intense interest and active research. However, the complex and variable nature of FMT makes it challenging to address its precise functionality and to assess clinical efficacy and safety in different disease contexts. In this review, we outline clinical applications, efficacy, durability, and safety of FMT and provide a comprehensive assessment of its procedural and administration aspects. The clinical applications of FMT in children and cancer immunotherapy are also described. We focus on data from human studies in IBD in contrast with rCDI to delineate the putative mechanisms of this treatment in IBD as a model, including colonization resistance and functional restoration through bacterial engraftment, modulating effects of virome/phageome, gut metabolome and host interactions, and immunoregulatory actions of FMT. Furthermore, we comprehensively review omics technologies, metagenomic approaches, and bioinformatics pipelines to characterize complex microbial communities and discuss their limitations. FMT regulatory challenges, ethical considerations, and pharmacomicrobiomics are also highlighted to shed light on future development of tailored microbiome-based therapeutics.

Abstract
BACKGROUND & AIMS Clostridioides difficile infection (CDI) is associated with high mortality. Fecal microbiota transplantation (FMT) is an established treatment for recurrent CDI, but its use for first or second CDI remains experimental. We aimed to investigate the effectiveness of FMT for first or second CDI in a real-world clinical setting. METHODS This multi-site Danish cohort study included patients with first or second CDI treated with FMT from June 2019 to February 2023. The primary outcome was cure of C. difficile-associated diarrhea (CDAD) 8 weeks after the last FMT treatment. Secondary outcomes included CDAD cure 1 and 8 weeks after the first FMT treatment and 90-day mortality following positive C. difficile test. RESULTS We included 467 patients, with 187 (40%) having their first CDI. The median patient age was 73 years (interquartile range [IQR], 58-82 years). Notably, 167 (36%) had antibiotic-refractory CDI, 262 (56%) had severe CDI, and 89 (19%) suffered from fulminant CDI. Following the first FMT treatment, cure of CDAD was achieved in 353 patients (76%; 95% confidence interval [CI], 71%-79%) at week 1. At week 8, 255 patients (55%; 95% CI, 50%-59%) maintained sustained effect. In patients without initial effect, repeated FMT treatments led to an overall cure of CDAD in 367 patients (79%; 95% CI, 75%-82%). The 90-day mortality was 10% (95% CI, 8%-14%). CONCLUSION Repeated FMT treatments demonstrate high effectiveness in managing patients with first or second CDI. Forwarding FMT in CDI treatment guidelines could improve patient survival.

Abstract
INTRODUCTION Fecal microbiota transfer (FMT) is a treatment to modulate the gastrointestinal microbiota. Its use in recurrent Clostridioides difficile infection (rCDI) is established throughout Europe and recommended in national and international guidelines. In Germany, the FMT is codeable in the hospital reimbursement system. A comprehensive survey on the frequency of use based on this coding is missing so far. MATERIAL AND METHODOLOGY Reports of the Institute for Hospital Remuneration (InEK), the Federal Statistical Office (DESTATIS), and hospital quality reports 2015-2021 were examined for FMT coding and evaluated in a structured expert consultation. RESULTS Between 2015 and 2021, 1,645 FMT procedures were coded by 175 hospitals. From 2016 to 2018, this was a median of 293 (274-313) FMT annually, followed by a steady decline in subsequent years to 119 FMT in 2021. Patients with FMT were 57.7% female, median age 74 years, and FMT was applied colonoscopically in 72.2%. CDI was the primary diagnosis in 86.8% of cases, followed by ulcerative colitis in 7.6%. DISCUSSION In Germany, FMT is used less frequently than in the European comparison. One application hurdle is the regulatory classification of FMT as a non-approved drug, which leads to significantly higher costs in manufacturing and administration and makes reimbursement difficult. The European Commission recently proposed a regulation to classify FMT as a transplant. This could prospectively change the regulatory situation of FMT in Germany and thus contribute to a nationwide offer of a therapeutic procedure recommended in guidelines.

Abstract
BACKGROUND Faecal microbiota transplantation (FMT) is effective for recurrent Clostridioides difficile infection (rCDI), but its effect varies inexplicably. AIMS To optimise the effectiveness of FMT for rCDI and validate determinants for effect METHODS: We conducted a cohort study, including all patients treated with FMT for rCDI between October 2018 and June 2020. Statistical process control was used to evaluate the impact of prospective quality improvement on the effect of single FMT treatments per 10-11 patients. Targeting an 80% effect, optimisations included changes to processing procedures, preparation and clinical application of FMT. The primary outcome was the resolution of Clostridioides difficile-associated diarrhoea at week 8. If CDI recurred, FMT was repeated. All patients were followed for 8 weeks after their latest FMT. RESULTS 183 patients with rCDI received 290 FMT treatments. A single FMT achieved resolution at week 8 in 127 (69%, 95% CI: 62%-76%), while repeated FMT cumulatively achieved resolution in 167/183 (91%, 95% CI: 86%-95%). The single FMT effect varied between 36% and 100% over time. In a mixed-effect model, patient age above 65 years, non-rCDI antibiotics at week 1 post-FMT, and donor were associated with effect. Neither increasing the dosages of faecal microbes nor standardising the processing improved outcomes. CONCLUSION FMT has a high cumulative effectiveness in patients with rCDI following multiple administrations, but the single FMT effect is variable and may be optimised using statistical process control. Optimising FMT by considering patient age, post-FMT antibiotics, donor and multiple administrations may improve the treatment outcomes. CLINICALTRIALS gov (Study identifier: NCT03712722).

Abstract
PURPOSE Clostridioides difficile infection (CDI) has a high mortality among older patients. Identification of older patients with CDI in increased mortality risk is important to target treatment and thereby reduce mortality. The aim of this study was to investigate mortality rates and compare frailty levels at discharge, measured by the record-based Multidimensional Prognostic Index (MPI), with age and severity of CDI as mortality predictors in patients with CDI diagnosed during hospitalisation. METHODS This was a population-based cohort study from Central Denmark Region, Denmark, including all patients ≥ 60 years with a positive CD toxin test without prior infection and diagnosed from 1 January to 31 December 2018. Frailty level, estimated from the electronic medical record, was defined as low, moderate, or severe frailty. CDI severity was graded according to international guidelines. Primary outcome was 90-day mortality. RESULTS We included 457 patients with median age 77 years (interquartile range 69-84) and females (49%). Overall, 90-day mortality was 28%, and this was associated with age (hazard ratio (HR): 2.71 (95% confidence interval 1.64-4.47)), CDI severity (HR 4.58 (3.04-6.88)) and frailty (HR 10.15 (4.06-25.36)). Frailty was a better predictor of 90-day mortality than both age (p < 0.001) and CDI severity (p = 0.04) with a receiver operating characteristic curve area of 77%. CONCLUSION The 90-day mortality among older patients with CDI in a Danish region is 28%. Frailty measured by record-based MPI at discharge outperforms age and disease severity markers in predicting mortality in older patients with CDI.

Abstract
Cardiometabolic diseases have become a leading cause of morbidity and mortality globally. They have been tightly linked to microbiome taxonomic and functional composition, with diet possibly mediating some of the associations described. Both the microbiome and diet are modifiable, which opens the way for novel therapeutic strategies. High-throughput omics techniques applied on microbiome samples (meta-omics) hold the unprecedented potential to shed light on the intricate links between diet, the microbiome, the metabolome and cardiometabolic health, with a top-down approach. However, effective integration of complementary meta-omic techniques is an open challenge and their application on large cohorts is still limited. Here we review meta-omics techniques and discuss their potential in this context, highlighting recent large-scale efforts and the novel insights they provided. Finally, we look to the next decade of meta-omics research and discuss various translational and clinical pathways to improving cardiometabolic health.

Abstract
OBJECTIVES The aim was to determine if Helicobacter pylori is transmitted from donors to recipients by faecal microbiota transplantation (FMT) via oral capsules. METHODS In a cohort of faeces donors not primarily screened for H. pylori, consecutive stool samples were retrospectively analysed by the H. pylori stool antigen test (SAT). Subsequently, we analysed recipient stool samples collected before and after receiving faeces donated by H. pylori SAT-positive donors, and we recorded recipient use of antibiotics and proton pump inhibitors. All stool samples were frozen upon collection and stored at -80°C until use. RESULTS Thirteen out of 40 faeces donors (33%; 95% CI, 20-48%) were H. pylori SAT-positive. Among those positive, five donors donated faeces for 28 capsule-based FMTs performed in 26 recipients with stool samples collected before and after FMT. At a median of 59 days (range, 7-84 days) after FMT, no recipients (0%; 95% CI, 0-11%) were H. pylori SAT-positive. DISCUSSION We found no occurrence of H. pylori transmission from healthy, asymptomatic donors to recipients by oral capsule-based FMT, although with a wide CI.

Abstract
Ulcerative colitis (UC) is a relapsing non-transmural chronic inflammatory disease of the colon characterized by bloody diarrhea. The etiology of UC is unknown. The goal is to reduce the inflammation and induce disease remission in UC patients with active disease. The aim of this study is to investigate the innovative treatment method used to promote disease remission in UC patients with active disease targeting gut dysbiosis. Immunosuppressants such as TNF-α blocker are used to promote disease remission in UC, but it is expensive and with side effects. Probiotic, prebiotic and diet are shown to be effective in maintaining disease remission. Fecal microbiota transplantation (FMT) might be the future therapy option to promote disease remission in UC patients with active disease. However, correct manufacturing and administration of the FMT are essential to achieve successful outcome. A few cohorts with FMT capsules show promising results in UC patients with active disease. However, randomized controlled clinical trials with long-term treatment and follow-up periods are necessary to show FMT capsules' efficacy to promote disease remission in UC patients.

Faecal microbiota transplantation for first or second Clostridioides difficile infection (EarlyFMT): a randomised, double-blind, placebo-controlled trial. Lancet Gastroenterol Hepatol 2022; 7:1083-1091. [PMID: 36152636 DOI: 10.1016/s2468-1253(22)00276-x] [Citation(s) in RCA: 30] [Impact Index Per Article: 15.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/25/2022] [Revised: 08/10/2022] [Accepted: 08/11/2022] [Indexed: 10/14/2022]
Abstract
BACKGROUND Clostridioides difficile infection is an urgent antibiotic-associated health threat with few treatment options. Microbiota restoration with faecal microbiota transplantation is an effective treatment option for patients with multiple recurring episodes of C difficile. We compared the efficacy and safety of faecal microbiota transplantation compared with placebo after vancomycin for first or second C difficile infection. METHODS We did a randomised, double-blind, placebo-controlled trial (EarlyFMT) at a university hospital in Aarhus, Denmark. Eligible patients were aged 18 years or older with first or second C difficile infection (defined as ≥3 watery stools [Bristol stool chart score 6-7] per day and a positive C difficile PCR test). Patients were randomly assigned (1:1) to faecal microbiota transplantation or placebo administered on day 1 and between day 3 and 7, after they had received 125 mg oral vancomycin four times daily for 10 days. Randomisation was done by investigators using a computer-generated randomisation list provided by independent staff. Patients and investigators were masked to the treatment group. The primary endpoint was resolution of C difficile-associated diarrhoea (CDAD) 8 weeks after treatment. We followed up patients for 8 weeks or until recurrence. We planned to enrol 84 patients with a prespecified interim analysis after 42 patients. The primary outcome and safety outcomes were analysed in the intention-to-treat population, which included all randomly assigned patients. The trial is registered with ClinicalTrials.gov, NCT04885946. FINDINGS Between June 21, 2021, and April 1, 2022, we consecutively screened 86 patients, of whom 42 were randomly assigned to faecal microbiota transplantation (n=21) or placebo (n=21). The trial was stopped after the interim analysis done on April 7, 2022 for ethical reasons because a significantly lower rate of resolution was identified in the placebo group compared with the faecal microbiota transplantation group (Haybittle-Peto boundary limit p<0·001). 19 (90%; 95% CI 70-99) of 21 patients in the faecal microbiota transplantation group and seven (33%, 95% CI 15-57) of 21 patients in the placebo group had resolution of CDAD at week 8 (p=0·0003). The absolute risk reduction was 57% (95% CI 33-81). Overall, 204 adverse events occurred, with one or more adverse events being reported in 20 of 21 patients in the faecal microbiota transplantation group and all 21 patients in the placebo group. Diarrhoea (n=23 in the faecal microbiota transplantation group; n=14 in the placebo group) and abdominal pain (n=14 in the faecal microbiota transplantation group; n=11 in the placebo group) were the most common adverse events. Three serious adverse events possibly related to study treatment occurred (n=1 in the faecal microbiota transplantation group; n=2 in the placebo group), but no deaths or colectomies during the 8-week follow-up. INTERPRETATION In patients with first or second C difficile infection, first-line faecal microbiota transplantation is highly effective and superior to the standard of care vancomycin alone in achieving sustained resolution from C difficile.

The Efficacy of Faecal Microbiota Transplant and Rectal Bacteriotherapy in Patients with Recurrent Clostridioides difficile Infection: A Retrospective Cohort Study. Cells 2022; 11:cells11203272. [PMID: 36291139 PMCID: PMC9600246 DOI: 10.3390/cells11203272] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/26/2022] [Revised: 09/29/2022] [Accepted: 10/12/2022] [Indexed: 11/18/2022] Open
Abstract
The most effective treatment for recurrent Clostridioides difficile infection (CDI) is faecal microbiota transplantation (FMT); however, the optimal route of administration is thus far unknown. This retrospective cohort study of 343 patients sought to evaluate the efficacy of treatment with FMT capsules, FMT enema, and rectal bacteriotherapy (RBT) during a five-year period. The primary endpoint was clinical resolution from CDI after eight weeks, and secondary endpoints were time to recurrence and death during the follow-up period. The proportion of patients with clinical resolution was 79.9% in the FMT capsule group, 53.3% in the FMT enema group, and 61.8% in the RBT group, corresponding to an adjusted odds ratio of 3.79 (CI: 1.82 to 8.26) in the FMT capsule group compared with FMT enema, and 2.92 (CI: 1.49 to 6.03) compared with RBT. The hazards ratio for recurrence within the first 12 months of follow-up was 0.24 (CI: 0.06 to 0.89) in the FMT capsule group compared with FMT enema, and 0.26 (CI: 0.08 to 0.91) compared with RBT. There was no difference in mortality. In conclusion, FMT capsules were more effective than both FMT enema and RBT as treatment of recurrent CDI and reduced the risk of further recurrences.

Abstract
Objective To systematically assess the current related methodological quality of guidelines for the diagnosis and treatment of Clostridioides difficile infection (CDI), revealing the heterogeneity and reasons for guideline recommendations for the diagnosis and treatment of CDI. Methods We searched electronic databases systematically between 2017 and 2021 to find the latest guidelines for the diagnosis and treatment of CDI. The Appraisal of Guidelines for Research and Evaluation (AGREE II) tool was used for quality assessment of the included guidelines. The main recommendations for the diagnosis and treatment of CDI in the guidelines were extracted and evaluated for consistency, and the level of evidence supporting these recommendations was further extracted and analysed. Results Fourteen guidelines for the diagnosis and treatment of CDI were finally included in this study. There were four guidelines, BSG and HIS, ASCRS, IDSA AND SHEA, and NICE, with an overall score of more than 60%, which is worthy of clinical recommendation. Further analysis of the consistency of the main recommendations for the diagnosis and treatment of CDI in the guidelines showed that the recommendations differed among guidelines. There are no unified classification criteria for the severity of CDI in current studies; some recommendations for the diagnosis and treatment of CDI do not provide evidence to support the recommendations, most recommendations cite low levels of evidence, and there is a lack of high-quality research evidence. Conclusion The quality of guidelines for the diagnosis and treatment of CDI is uneven. Recommendations on the diagnosis and treatment of CDI have also varied in the guidelines for the past 5 years. Improvements of the aforementioned factors associated with causing heterogeneity would be a rational approach by guideline developers to further update guidelines for the diagnosis and treatment of CDI.

Therap Adv Gastroenterol 2022; 15:17562848221078441. [PMID: 35463939 PMCID: PMC9019313 DOI: 10.1177/17562848221078441] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/20/2021] [Accepted: 01/19/2022] [Indexed: 02/04/2023] Open
Abstract
BACKGROUND The health-related quality of life (HrQoL) can be substantially affected in patients with recurrent Clostridioides difficile infection (rCDI) but the impact of effective treatment of the infection remains unclear. This study aimed to evaluate the HrQoL in patients with rCDI and estimate the gain in HrQoL associated with effective treatment of rCDI. METHODS Patients' HrQoL was estimated based on EuroQol 5-Dimensions 3-Levels (EQ-5D-3L) questionnaires obtained from a Danish randomised controlled trial (RCT). In the RCT, 64 patients with rCDI were randomised to receive either vancomycin (n = 16), fidaxomicin (n = 24) or faecal microbiota transplantation (FMT) preceded by vancomycin (n = 24). The primary outcome in the RCT was rCDI resolution. Patients were closely monitored during the RCT, and rescue FMT was offered to those who failed their primary treatment. Patients' HrQoL was measured at baseline and at 8- and 26-weeks follow-up. Linear regression analyses conditional on the differences between baseline and follow-up measurements were used to assess statistical significance (p < 0.05). RESULTS Within 26 weeks of follow-up, 13 (81%) patients treated with vancomycin, 12 (50%) patients treated with fidaxomicin, and 3 (13%) patients treated with FMT had a subsequent recurrence and received a rescue FMT. The average HrQoL for untreated patients with rCDI was 0.675. After receiving effective treatment, this value increased by 0.139 to 0.813 (p < 0.001) at week 8 and by 0.098 to 0.773 (p = 0.003) at week 26 of follow-up compared with baseline. CONCLUSION The HrQoL was adversely affected in patients with an active episode of rCDI but increased substantially after receiving an effective treatment algorithm in which rescue FMT was provided in case of a primary treatment failure. TRIAL REGISTRATION The RCT was preregistered at EudraCT (j.no. 2015-003004-24, https://www.clinicaltrialsregister.eu/ctr-search/trial/2015-003004-24/results) and at ClinicalTrials.gov (study identifier NCT02743234, https://clinicaltrials.gov/ct2/show/NCT02743234).

Long-Term Safety Following Faecal Microbiota Transplantation as a Treatment for Recurrent Clostridioides difficile Infection Compared with Patients Treated with a Fixed Bacterial Mixture: Results from a Retrospective Cohort Study. Cells 2022; 11:cells11030435. [PMID: 35159245 PMCID: PMC8834574 DOI: 10.3390/cells11030435] [Citation(s) in RCA: 11] [Impact Index Per Article: 5.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/19/2021] [Revised: 01/21/2022] [Accepted: 01/22/2022] [Indexed: 02/08/2023] Open
Abstract
Faecal microbiota transplantation (FMT) is the recommended treatment for recurrent C. difficile infection (rCDI) following a second recurrence. FMT is considered safe in the short term when procedures for the screening of donors and transferred material are followed. However, the long-term safety profile of FMT treatment is largely unknown. In a retrospective cohort study, we assessed the long-term safety of patients treated for rCDI with FMT or a fixed bacterial mixture, rectal bacteriotherapy (RBT). The overall survival, risk of hospital admission, onset of certain pre-specified diseases (cancer, diabetes mellitus, hypertension and inflammatory bowel disease) and risk of being diagnosed with a multidrug-resistant organism were assessed by undertaking a review of the treated patients’ medical records for up to five years following treatment. A total of 280 patients were treated for rCDI with FMT (n = 145) or RBT (n = 135) between 2016 and 2020. In the five years following treatment, there were no differences in survival (adjusted hazard ratio (aHR) 1.03; 95% CI 0.68–1.56), p = 0.89), risk of hospital admission ((aHR 0.92; 95% CI 0.72–1.18), p = 0.5) or onset of any of the analysed diseases. In conclusion, FMT was not associated with increased mortality, risk of hospital admission or onset of disease following treatment when compared with RBT.
