Background: Faecal microbiota transplant (FMT) is a highly effective therapy for recurrent Clostridioides difficile infection (rCDI) with cure rates ranging between 85 and 92%. The FMT role for primary Clostridioides difficile infection (CDI) has yet to be settled because of limited data and small-sample studies presented in the current literature. Our study goals were to report the risk factors and the risk of recurrence after FMT for each CDI episode (first, second, and third) and to explore if there is a role of FMT in primary severe CDI. Methods: We conducted a retrospective study to analyze the clinical characteristics and the outcomes of 96 FMT patients with a prior 10 day course of antibiotic treatment in the medical records, of which 71 patients with recurrent CDI and 25 patients with a primary CDI. Results: The overall primary cure rate in our study was 88.5% and the primary cure rate for the severe forms was 85.7%. The data analysis revealed 5.25%, 15.15%, and 27.3% FMT recurrence rates for primary, secondary, and tertiary severe CDI. The risk of recurrence was significantly associated with FMT after the second and the third CDI severe episodes (p < 0.05), but not with FMT after the first severe CDI episode. Conclusions: This study brings new data in supporting the FMT role in CDI treatment, including the primary severe CDI, however, further prospective and controlled studies on larger cohorts should be performed in this respect.

Abstract Background There are limited options for Clostridioides difficile infection (CDI) refractory to conventional antibiotic therapy (metronidazole, vancomycin, or fidaxomicin). Fecal microbiota transplant (FMT) is considered a safe and effective treatment for recurrent CDI but has not been widely utilized for refractory CDI due to concerns about safety. Even when included in studies, refractory CDI has not been analyzed separately from recurrent CDI. We reviewed cases of FMT performed in the inpatient setting for CDI to evaluate its safety and efficacy for refractory CDI. Methods Patients who received FMT inpatient at University of Virginia Health System for recurrent or refractory CDI after Infectious Diseases and Gastroenterology consultation signed informed consent acknowledging that FMT was considered investigational use in CDI not responding to standard of care as per 2014 FDA guidance. Charts were reviewed as part of quality improvement efforts to evaluate safety and efficacy of FMT in inpatient setting. Results Starting in July 2014, 13 patients received FMT for CDI as inpatients. Six received FMT for recurrent CDI, with four having complete resolution, one had recurrent CDI, and one had persistent C. difficile-negative diarrhea, for cure rate of 83%, comparable to published studies. Seven patients received FMT for refractory CDI, with three resulting in complete resolution. One responded to FMT but refused further care, one died from multiorgan failure after initial response to FMT that was possibly related to CDI, strongyloides, and/or CMV. Two patients had ongoing diarrhea suggestive of post-infectious irritable bowel syndrome, one was C. difficile-negative and one was not tested. The cure rate was 57%, lower than that of the recurrent CDI, but without any clear evidence of microbiologic failure. Outcome of patients undergoing FMT for CDI in the inpatient setting at University of Virginia Health System Conclusion Cure rate for FMT for refractory CDI was lower than recurrent CDI, but review of the cases of treatment failures did not reveal any microbiologic evidence of failure. FMT should be considered an alternative option when treating refractory CDI. Disclosures All Authors: No reported disclosures

Fecal microbiota transplantation (FMT) is highly effective in recurrent Clostridioides difficile infection (CDI); increasing evidence supports FMT in severe or fulminant Clostridioides difficile infection (SFCDI). However, the multifactorial mechanisms that underpin the efficacy of FMT are not fully understood. Systems biology approaches using high-throughput technologies may help with mechanistic dissection of host-microbial interactions. Here, we have undertaken a deep phenomics study on four adults receiving sequential FMT for SFCDI, in which we performed a longitudinal, integrative analysis of multiple host factors and intestinal microbiome changes. Stool samples were profiled for changes in gut microbiota and metabolites and blood samples for alterations in targeted epigenomic, metabonomic, glycomic, immune proteomic, immunophenotyping, immune functional assays, and T-cell receptor (TCR) repertoires, respectively. We characterised temporal trajectories in gut microbial and host immunometabolic data sets in three responders and one non-responder to sequential FMT. A total of 562 features were used for analysis, of which 78 features were identified, which differed between the responders and the non-responder. The observed dynamic phenotypic changes may potentially suggest immunosenescent signals in the non-responder and may help to underpin the mechanisms accompanying successful FMT, although our study is limited by a small sample size and significant heterogeneity in patient baseline characteristics. Our multi-omics integrative longitudinal analytical approach extends the knowledge regarding mechanisms of efficacy of FMT and highlights preliminary novel signatures, which should be validated in larger studies.

Introduction: Fecal microbiota transplant (FMT) has been shown to be an effective treatment for recurrent Clostridioides difficile infection (CDI). Immunosuppression is one of the risk factors for CDI. However, most of the trials evaluating efficacy of FMT have excluded immunocompromised patients. Patients with hematological cancers represent a major class of immunocompromised patients. Hence, we performed a meta-analysis to evaluate the efficacy of FMT in patients with hematological cancer for the treatment of recurrent CDI. Methods: A systematic search of Medline, Embase, and Web of Science was performed from January 2000 up to December 2018. Articles included for meta-analysis were case series and case reports that assessed efficacy of FMT in hematological cancer patients were included. Study quality was assessed using the Newcastle-Ottawa scale. The main outcomes were pooled proportions of patients achieving cure after first FMT. The cure rate was defined as resolution of diarrhea without any recurrence. Results: 10 studies (5 case series and 5 case reports) were included in the analysis, making up 29 patients who underwent 38 total FMT procedures. The follow up period ranged from 1- 14 months. Of the included patients, 17 had leukemia, 10 had lymphoma and 2 patients had multiple myeloma and myelodysplastic syndrome each. 7 of these patients had undergone hematopoietic stem cell transplant. The pooled cure rate was 82% [confidence interval (CI) 67-94%] after 1 FMT with no heterogeneity (I2=0%). Minor publication bias was seen on visual inspection of funnel plot. FMT was generally well tolerated by these patients. No serious side effects were reported in any study. One of the studies reported death due to cardiac arrest 5 days after FMT which was thought to be unrelated to the procedure. Mild side effects including mild abdominal pain, transient diarrhea, fecal urgency, constipation and nausea were reported in 5 patients. Conclusion: Based on limited observational data, FMT seems to be an effective and safe modality for management of recurrent CDI in patients with hematological cancers. However, further prospective clinical trials are needed to establish its safety as a first line therapy for recurrent CDI in this population.

AbstractFecal microbiota transplantation (FMT) is the process of transplanting stool from a healthy donor into the gut of a diseased individual for therapeutic purposes. It has a clearly defined role in the treatment of recurrent Clostridium difficile (reclassified as “Clostridioides difficile”) infection (CDI), with cure rates over 90% and decreased rates of subsequent recurrence compared with anti-CDI antibiotics. There is emerging evidence that FMT is also effective in the treatment of severe and fulminant CDI, with associated decreases in mortality and colectomy rates compared with standard antibiotic therapy. FMT shows promise as salvage therapy for critically-ill CDI patients refractory to maximum medical therapy and not deemed to be surgical candidates. FMT should be considered early in the course of severe CDI and should be delivered immediately in patients with signs of refractory CDI. Expansion of FMT's use along the spectrum of CDI severity has potential to decrease associated rates of mortality and colectomy.

Clostridioides Difficile Infection

Clostridioides difficile infection (CDI) is the leading cause of antibiotic-associated diarrhea, especially in hospitalized elderly patients, representing a global public health concern. Clinical presentations vary from mild diarrhea to severe pseudomembranous colitis that may progress to toxic megacolon or intestinal perforation. Antibiotic therapy is recognized as a risk factor and exacerbates dysbiosis of the intestinal microbiota, whose role in CDI is increasingly acknowledged. A clinically challenging complication is the development of recurrent disease (rCDI). In this study, using amplicon metagenomics, we compared the fecal microbiota of CDI and rCDI patients (sampled at initial and recurrent episode) and of non-infected controls. We also investigated whether CDI severity relates to specific microbiota compositions. rCDI patients showed a significantly decreased bacterial diversity as compared to controls (p < 0.01). The taxonomic composition presented significant shifts: both CDI and rCDI patients displayed significantly increased frequencies of Firmicutes, Peptostreptococcaceae, Clostridium XI, Clostridium XVIII, and Enterococcaceae. Porphyromonadaceae and, within it, Parabacteroides displayed opposite behaviors in CDI and rCDI, appearing discriminant between the two. Finally, the second episode of rCDI was characterized by significant shifts of unclassified Clostridiales, Escherichia/Shigella and Veillonella. No peculiar taxa composition correlated with the severity of infection, likely reflecting the role of host-related factors in determining severity.
