Effect of Fecal Microbiota Transplantation on Recurrence in Multiply Recurrent Clostridium difficile Infection: A Randomized Trial.

ABSTRACT:

Background

To date, evidence for the efficacy of fecal microbiota transplantation (FMT) in recurrent Clostridium difficile infection (CDI) has been limited to case series and open-label clinical trials.

Objective

To determine the efficacy and safety of FMT for treatment of recurrent CDI.

Design

Randomized, controlled, double-blind clinical trial. (ClinicalTrials.gov: NCT01703494).

Setting

Two academic medical centers.

Patients

46 patients who had 3 or more recurrences of CDI and received a full course of vancomycin for their most recent acute episode.

Intervention

Fecal microbiota transplantation with donor stool (heterologous) or patient's own stool (autologous) administered by colonoscopy.

Measurements

The primary end point was resolution of diarrhea without the need for further anti-CDI therapy during the 8-week follow-up. Safety data were compared between treatment groups via review of adverse events (AEs), serious AEs (SAEs), and new medical conditions for 6 months after FMT. Fecal microbiota analyses were performed on patients' stool before and after FMT and also on donors' stool.

Results

In the intention-to-treat analysis, 20 of 22 patients (90.9%) in the donor FMT group achieved clinical cure compared with 15 of 24 (62.5%) in the autologous FMT group (P = 0.042). Resolution after autologous FMT differed by site (9 of 10 vs. 6 of 14 [P = 0.033]). All 9 patients who developed recurrent CDI after autologous FMT were free of further CDI after subsequent donor FMT. There were no SAEs related to FMT. Donor FMT restored gut bacterial community diversity and composition to resemble that of healthy donors.

Limitation

The study included only patients who had 3 or more recurrences and excluded those who were immunocompromised and aged 75 years or older.

Conclusion

Donor stool administered via colonoscopy seemed safe and was more efficacious than autologous FMT in preventing further CDI episodes.

Project description:BackgroundFecal microbiota transplantation (FMT) is an effective treatment for recurrent Clostridium difficile infection (rCDI). The use of freeze-dried, encapsulated donor material for FMT (cap-FMT) allows for an easy route of administration and remains clinically effective in the majority of rCDI patients. We hypothesized that specific shifts in the microbiota in response to cap-FMT could predict clinical outcome. We further evaluated the degree of donor microbiota engraftment to determine the extent that donor transfer contributed to recovery.ResultsIn total, 89 patients were treated with 100 separate cap-FMTs, with a success rate (no rCDI 60 days post cap-FMT) of 80%. Among responders, the lower alpha diversity (ANOVA P < 0.05) observed among patient's pre-FMT samples was restored following cap-FMT. At 1 week post-FMT, community composition varied by clinical outcome (ANOSIM P < 0.001), with similar abundances among families (Lachnospiraceae, Ruminococcaceae, and Bacteroidaceae) in responder and donor samples. Families that showed differential abundances by outcome (response vs. recurrence) from samples collected 7 days following cap-FMT were used to construct a regression tree-based model to predict recurrence. Results showed a training accuracy of 100% to predict recurrence and the model was 97% accurate against a test data set of samples collected 8-20 days following cap-FMT. Evaluation of the extent of engraftment using the Bayesian algorithm SourceTracker revealed that approximately 50% of the post-FMT communities of responders were attributable to donor microbiota, while an additional 20-30% of the communities were similar to a composite healthy microbiota consisting of all donor samples.ConclusionsRegression tree-based analyses of microbial communities identified taxa significantly related to clinical response after 7 days, which can be targeted to improve microbial therapeutics. Furthermore, reinstatement of a healthy assemblage following cap-FMT was only partially attributable to explicit donor engraftment and continued to develop towards an overall healthy assemblage, independent of donor.

Project description:Clostridium difficile causes antibiotic-associated diarrhea and pseudomembraneous colitis and is responsible for a large and increasing fraction of hospital-acquired infections. Fecal microbiota transplantation (FMT) is an alternate treatment option for recurrent C. difficile infection (RCDI) refractory to antibiotic therapy. It has recently been discussed favorably in the clinical and scientific communities and is receiving increasing public attention. However, short- and long-term health consequences of FMT remain a concern, as the effects of the transplanted microbiota on the patient remain unknown. To shed light on microbial events associated with RCDI and treatment by FMT, we performed fecal microbiota analysis by 16S rRNA gene amplicon pyrosequencing of 14 pairs of healthy donors and RCDI patients treated successfully by FMT. Post-FMT patient and healthy donor samples collected up to one year after FMT were studied longitudinally, including one post-FMT patient with antibiotic-associated relapse three months after FMT. This analysis allowed us not only to confirm prior reports that RCDI is associated with reduced diversity and compositional changes in the fecal microbiota, but also to characterize previously undocumented post-FMT microbiota dynamics. Members of the Streptococcaceae, Enterococcaceae, or Enterobacteriaceae were significantly increased and putative butyrate producers, such as Lachnospiraceae and Ruminococcaceae were significantly reduced in samples from RCDI patients before FMT as compared to post-FMT patient and healthy donor samples. RCDI patient samples showed more case-specific variations than post-FMT patient and healthy donor samples. However, none of the bacterial groups were invariably associated with RCDI or successful treatment by FMT. Overall microbiota compositions in post-FMT patients, specifically abundances of the above-mentioned Firmicutes, continued to change for at least 16 weeks after FMT, suggesting that full microbiota recovery from RCDI may take much longer than expected based on the disappearance of diarrheal symptoms immediately after FMT.

Project description:Background & aimsA significant fraction of patients with recurrent Clostridium difficile infections (CDI) have inflammatory bowel disease (IBD). Fecal microbiota transplantation (FMT) can break the cycle of CDI recurrence and can be performed without evaluation of the colon. We evaluated the efficacy of colonoscopic FMT in patients with and without IBD, and whether we could identify IBD in patients during this procedure.MethodsWe collected clinical meta-data and colonoscopy results from 272 consecutive patients that underwent FMT for recurrent CDI at the University of Minnesota from 2008 through 2015. Patients had at least 2 spontaneous relapses of CDI following their initial episode and did not clear the infection after 1 extended antibiotic regimen. We collected random mucosal biopsies from patients' right colons to identify lymphocytic or collagenous colitis during the FMT procedure. Failure or success in clearing CDI was determined within or at 2 months after the FMT.ResultsOf patients undergoing FMT, 15% had established IBD and 2.6% were found to have IBD during the FMT procedure. A single colonoscopic FMT cleared CDI from 74.4% of patients with IBD and 92.1% of patients without IBD (P = .0018). Patients had similar responses to FMT regardless of immunosuppressive therapy. More than one-quarter of patients with IBD (25.6%) had a clinically significant flare of IBD after FMT. Lymphocytic colitis was documented in 7.4% of patients with endoscopically normal colon mucosa; only 3 of these patients (20%) required additional treatment for colitis after clearance of CDI.ConclusionsBased on an analysis of 272 patients, FMT is somewhat less effective in clearing recurrent CDI from patients with IBD, compared with patients without IBD, regardless of immunosuppressive therapy. More than 25% of patients with IBD have a disease flare following FMT. Lymphocytic colitis did not affect the outcome of FMT, but a small fraction of these patients required pharmacologic treatment after the procedure.
