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., (Copyright © 2021 AGA Institute.

Background & Aims: Fecal microbiota transplantation (FMT) is recommended for recurrent Clostridioides difficile infection (CDI). FMT cures nearly 80% of patients with severe or fulminant CDI (SFCDI) when utilized in a sequential manner. We compared outcomes of hospitalized patients before and after implementation of an FMT program for SFCDI and investigated whether the changes could be directly attributed to the FMT program., Methods: We performed a retrospective analysis of characteristics and outcomes of patients hospitalized for SFCDI (430 hospitalizations) at a single center, from January 2009 through December 2016. We performed subgroup analyses of 199 patients with fulminant CDI and 110 patients with refractory SFCDI (no improvement after 5 or more days of maximal anti-CDI antibiotic therapy). We compared CDI-related mortality within 30 days of hospitalization, CDI-related colectomy, length of hospital stay, and readmission to the hospital within 30 days before (2009-2012) vs after (2013-2016) implementation of the inpatient FMT program., Results: CDI-related mortality and colectomy were lower after implementation of the FMT program. Overall, CDI-related mortality was 10.2% before the FMT program was implemented vs 4.4% after (P = .02). For patients with fulminant CDI, CDI-related mortality was 21.3% before the FMT program was implemented vs 9.1% after (P = .015). For patients with refractory SFCDI, CDI-related mortality was 43.2% before the FMT program vs 12.1% after (P < .001). The FMT program significantly reduced CDI-related colectomy in patients with SFCDI (6.8% before vs 2.7% after; P = .041), in patients with fulminant CDI (15.7% before vs 5.5% after; P = .017), and patients with refractory SFCDI (31.8% vs 7.6%; P = .001). The effect of FMT program implementation on CDI-related mortality remained significant for patients with refractory SFCDI after we accounted for the underlying secular trend (odds ratio, 0.09 for level change; P = .023)., Conclusions: An FMT program significantly decreased CDI-related mortality among patients hospitalized with refractory SFCDI., (Copyright © 2020 AGA Institute.

Fecal microbiota transplant (FMT) is recommended for Clostridium difficile infection (CDI) treatment; however, use in solid organ transplantation (SOT) patients has theoretical safety concerns. This multicenter, retrospective study evaluated FMT safety, effectiveness, and risk factors for failure in SOT patients. Primary cure and overall cure were defined as resolution of diarrhea or negative C difficile stool test after a single FMT or after subsequent FMT(s) ± anti-CDI antibiotics, respectively. Ninety-four SOT patients underwent FMT, 78% for recurrent CDI and 22% for severe or fulminant CDI. FMT-related adverse events (AE) occurred in 22.3% of cases, mainly comprising self-limiting conditions including nausea, abdominal pain, and FMT-related diarrhea. Severe AEs occurred in 3.2% of cases, with no FMT-related bacteremia. After FMT, 25% of patients with underlying inflammatory bowel disease had worsening disease activity, while 14% of cytomegalovirus-seropositive patients had reactivation. At 3 months, primary cure was 58.7%, while overall cure was 91.3%. Predictors of failing a single FMT included inpatient status, severe and fulminant CDI, presence of pseudomembranous colitis, and use of non-CDI antibiotics at the time of FMT. These data suggest FMT is safe in SOT patients. However, repeated FMT(s) or additional antibiotics may be needed to optimize rates of cure with FMT., (© 2018 The American Society of Transplantation and the American Society of Transplant Surgeons.)

Fecal microbiota transplantation (FMT) is an effective treatment for recurrent Clostridium difficile infection (rCDI), with cure rates higher than 80%. 1-3 FMT failure is defined as diarrhea and a positive stool laboratory test for C difficile at any point during the 8-week follow-up period after FMT. 4 ., (Copyright © 2018 AGA Institute.

Background: New treatments are needed as Clostridium difficile infection (CDI) is becoming increasingly formidable. Fecal microbiota transplantation (FMT) has a 90% success rate in the treatment of recurrent CDI. However, evidence regarding its safety, efficacy, and effect on disease activity in patients with inflammatory bowel disease (IBD) is lacking., Methods: This cohort study used data from 8 national and international academic centers. Patients with established IBD who underwent FMT for recurrent CDI were followed for a minimum of 3 months. The primary outcome was CDI recurrence at 3 months after FMT. The secondary outcomes were (1) IBD activity and severity at 3 months based on the judgment of the treating physician, endoscopic findings, and clinical disease activity scores; and (2) safety., Results: Sixty-seven patients were included in the analysis. Thirty-five (52%) had Crohn's disease, 31 (46%) ulcerative colitis, and one indeterminate colitis with 43 (64%) patients on an immunosuppressive agent at the time of FMT. The initial FMT was successful in 53 (79%) patients. After the FMT, IBD disease activity was reported as improved in 25 (37%), no change in 20 (30%), and worse in 9 (13%) patients. Serious adverse events included colectomy (1.4%), hospitalization for CDI (2.9%), hospitalization for IBD flare (2.9%), small bowel obstruction (1.4%), CMV colitis (1.4%), and pancreatitis (1.4%)., Discussion: The overall CDI cure rates were high, with a large percentage of patients experiencing clinical improvement of their IBD after FMT. A minority of patients developed an IBD flare. No severe adverse events directly attributable to FMT were found in this largest reported series of recurrent or refractory CDI patients with concurrent IBD.

Objectives: Fecal microbiota transplant (FMT) is a highly efficacious treatment for recurrent or refractory Clostridium difficile infection (CDI); however, 10-20% of patients fail to achieve cure after a single FMT. The aim of this study was to identify risk factors associated with FMT failure and to develop and validate a prediction model for FMT failure., Methods: Patient characteristics, CDI history, FMT characteristics, and outcomes data for patients treated between 2011 and 2015 at three academic tertiary referral centers were prospectively collected. Early FMT failure was defined as non-response or recurrence of diarrhea associated with positive stool C. difficile toxin or PCR within 1 month of FMT. Late FMT failure was defined as recurrence of diarrhea associated with positive stool C. difficile toxin or PCR between 1 and 3 months of the FMT. Patient data from two centers were used to determine independent predictors of FMT failure and to build a prediction model. A risk index was constructed based on coefficients of final predictors. The patient cohort from the third center was used to validate the prediction model., Results: Of 328 patients in the developmental cohort, 73.5% (N=241) were females with a mean age of 61.4±19.3 years; 19.2% (N=63) had inflammatory bowel disease (IBD), and 23.5% (N=77) were immunocompromised. The indication for FMT was recurrent CDI in 87.2% (N=286) and severe or severe-complicated in 12.8% (N=42). FMT was performed as an inpatient in 16.7% (N=54). The stool source was patient-directed donors in 40% (N=130) of cases. The early FMT failure rate was 18.6%, and the late failure rate was 2.7%. In the multivariable analysis, predictors of early FMT failure included severe or severe-complicated CDI (odds ratio (OR) 5.95, 95% confidence interval (CI): 2.26-15.62), inpatient status during FMT (OR 3.78, 95% CI: 1.55-9.24), and previous CDI-related hospitalization (OR 1.43, 95% CI: 1.18-1.75); with each additional hospitalization, the odds of failure increased by 43%. Risk scores ranged from 0 to 13, with 0 indicating low risk, 1-2 indicating moderate risk, and ≥3 indicating high risk. In the developmental cohort, early FMT failure rates were 5.6% for low risk, 12.7% for moderate risk, and 41% for high-risk patients. Of 134 patients in the validation cohort, 57% (N=77) were females with a mean age of 66±18.1 years; 9.7% (N=13) had IBD, and 17.9% (N=24) were immunocompromised. The early FMT failure rate at 1 month was 19.4%, with an additional 3% failing by 3 months. In the validation cohort, FMT failure rates were 2.1% for low risk, 16.1% for moderate risk, and 35.7% for high risk patients. The area under the receiver operating characteristic curve (AUROC) for FMT failure was 0.81 in the developmental cohort and 0.84 in the validation cohort., Conclusions: Severe and severe-complicated indication, inpatient status during FMT, and the number of previous CDI-related hospitalizations are strongly associated with early failure of a single FMT for CDI. The novel prediction model has good discriminative power at identifying individuals who are at high risk of failure after FMT therapy and may assist the treating physician in subsequent management plans.

Introduction: The risk of a new Clostridium difficile infection (CDI) after FMT is unknown if non-CDI antibiotics are required. It is uncertain if anti-CDI prophylaxis or probiotics would reduce risk. We therefore aimed to compare the risk of CDI with and without antibiotic exposure and the benefit of concomitant anti-CDI antibiotic or probiotic prophylaxis.Methods: This is a multicenter retrospective study carried out at three large FMT referral centers of patients who underwent FMT for recurrent CDI. Patients were assessed for antibiotic use, as well as concomitant use of prophylactic anti-CDI antibiotics or probiotics. Time to CDI recurrence after FMT was evaluated using the Kaplan-Meier method.Results: A total of 404 patients were included: 63% were females, with a mean age of 61.3 ± 18.8 years. Mean length of post-FMT follow-up was 18.1 ± 11.9 months (range 2.2-45.2). Among the entire cohort 8.1% (n = 33) experienced a CDI recurrence. Overall, 111 patients (27.4%) used a non-CDI antibiotic, of which 16.2% (n = 18) experienced a CDI recurrence. Patients who used non-CDI antibiotics were more likely to develop CDI (HR 8.44, 95% CI 4.21-16.93, p < 0.001). The risk of CDI recurrence was not different between patients who received anti-CDI antibiotic prophylaxis to those who did not (HR = 1.88, 95% CI 0.72-4.86, p = 0.2); however, probiotic prophylaxis was associated with a greater risk of CDI recurrence (HR = 2.65, 95% CI 1.02-6.86, p = 0.045).Conclusion: Non-CDI antibiotic use was not uncommon after successful FMT and significantly increased the risk of a new episode of CDI. In this study, we found that the prophylactic use of anti-CDI antibiotics or probiotics was not protective. [ABSTRACT FROM AUTHOR]

Importance: Fecal microbiota transplantation (FMT) is effective in preventing recurrent Clostridium difficile infection (RCDI). However, it is not known whether clinical efficacy differs by route of delivery.Objective: To determine whether FMT by oral capsule is noninferior to colonoscopy delivery in efficacy.Design, Setting, and Participants: Noninferiority, unblinded, randomized trial conducted in 3 academic centers in Alberta, Canada. A total of 116 adult patients with RCDI were enrolled between October 2014 and September 2016, with follow-up to December 2016. The noninferiority margin was 15%.Interventions: Participants were randomly assigned to FMT by capsule or by colonoscopy at a 1:1 ratio.Main Outcomes and Measures: The primary outcome was the proportion of patients without RCDI 12 weeks after FMT. Secondary outcomes included (1) serious and minor adverse events, (2) changes in quality of life by the 36-Item Short Form Survey on a scale of 0 (worst possible quality of life) to 100 (best quality of life), and (3) patient perception on a scale of 1 (not at all unpleasant) to 10 (extremely unpleasant) and satisfaction on a scale of 1 (best) to 10 (worst).Results: Among 116 patients randomized (mean [SD] age, 58 [19] years; 79 women [68%]), 105 (91%) completed the trial, with 57 patients randomized to the capsule group and 59 to the colonoscopy group. In per-protocol analysis, prevention of RCDI after a single treatment was achieved in 96.2% in both the capsule group (51/53) and the colonoscopy group (50/52) (difference, 0%; 1-sided 95% CI, -6.1% to infinity; P < .001), meeting the criterion for noninferiority. One patient in each group died of underlying cardiopulmonary illness unrelated to FMT. Rates of minor adverse events were 5.4% for the capsule group vs 12.5% for the colonoscopy group. There was no significant between-group difference in improvement in quality of life. A significantly greater proportion of participants receiving capsules rated their experience as "not at all unpleasant" (66% vs 44%; difference, 22% [95% CI, 3%-40%]; P = .01).Conclusions and Relevance: Among adults with RCDI, FMT via oral capsules was not inferior to delivery by colonoscopy for preventing recurrent infection over 12 weeks. Treatment with oral capsules may be an effective approach to treating RCDI.Trial Registration: clinicaltrials.gov Identifier: NCT02254811. [ABSTRACT FROM AUTHOR]
