Abstract

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.
