Case series of successful treatment with fecal microbiota transplant (FMT) oral capsules mixed from multiple donors even in patients previously treated with FMT enemas for recurrent Clostridium difficile infection

RATIONALE: Studies have shown that fecal microbiota transplantation (FMT) is a safe and highly efficient treatment for recurrent Clostridium difficile infection (rCDI). However, it is still unknown if one versus multiple donors or enemas versus capsule FMT are most efficient. PATIENT CONCERNS: 10 patients with at least 3 previous episodes of CDI were offered treatment with FMT capsules. 9 patients decided to participate. DIAGNOSES: In this study, we treated 9 patients (25–86 years) with rCDI. INTERVENTIONS: From October to November 2016, a total of 9 patients with recurrent CDI were treated with oral fecal microbiota capsules, with mixed donor feces from 4 donors with high microbiota diversity. All patients received treatment with vancomycin prior to the capsule regime. OUTCOME: Patients had previous recurrences ranging from 2 to 10 recurrences. All 9 patients were successfully treated without recurrence after 180 days follow-up, even 2 patients previously treated with FMT enemas. LESSONS: FMT capsules based on multiple donors are highly efficient in patients with rCDI.
