This randomized controlled trial examined bile acid composition in patients with recurrent Clostridioides difficile infection treated with fecal microbiota transplantation (FMT), a bacterial mixture, or vancomycin. The study found that FMT re-established a donor-like bile acid composition faster than vancomycin, with a notable shift in secondary bile acids observed in all treatment groups post-intervention.
Key findings
- FMT led to a faster re-establishment of secondary bile acids compared to vancomycin and bacterial mixture.
- A higher proportion of primary bile acids was found in patients than in healthy stool donors.
- The rise in secondary bile acids correlated with the detection of bile acid-transforming bacteria in about half of participants.
Why it matters
Understanding the role of bile acid composition in recurrent C. difficile infection treatment can inform therapeutic strategies. The faster normalization of bile acids with FMT may reduce the risk of recurrence, highlighting the importance of microbiota in gastrointestinal health.
