Background:
Faecal microbiota transplantation (FMT) is currently being established as a second-line treatment for recurrent Clostridium difficile infection. FMT is further being considered for other infectious and inflammatory conditions. Safe and reproducible methods for donor screening, laboratory processing and clinical application of FMT are warranted.
Methods:
Here, we describe the development of a complete clinical application framework for FMT. The framework has been developed to comply with the European Tissue Act, thus considering donor faeces for FMT comparable to a human tissue and not a drug.
Results:
Recruitment and screening of potential faeces donors took place in the public blood donor setting and consisted of questionnaires, blood sampling and faecal sample analysis. Once approved, and following their written informed consent, eligible donors were invited for voluntary faecal donation. Laboratory processing protocols describe the initial handling, cryopreservation and thawing for clinical application. The clinical FMT procedures took place in a gastroenterological setting using a nasojejunal tube or colonoscopy, and follow-ups were performed at 1, 8 and 26 weeks after FMT. Complete traceability of essential equipment, faecal samples and donor-recipient matching data will be maintained and secured for 30 years.
Conclusion:
A clinical FMT service should be consolidated by a complete documentation system that complies with the European Tissue Act. In this paper, we provide a description of such a framework.
