Le transfert de microbiote fécal lors d'infections récidivantes à Clostridium difficile. Cadre et aspects pharmacotechniques

The fecal microbiota transplantation consists in introducing a preparation constituted by a dilution of stools of a healthy donor in the digestive tract of a patient recipient, to restore his intestinal physiological balance. This therapeutic approach was the subject of numerous studies showing its efficiency in the treatment of the recurrent infections with Clostridium difficile. The fecal microbiota transplantation has now a high level of clinical evidence, which explains that it appears in various international recommendations. In France, the fecal microbiota transplantation responds to the definition of a medication and can be executed as a pharmaceutical preparation or as an experimental drug for clinical trials under the responsibility of a hospital pharmacy. The objective of this paper is to propose a definition of a framework and to describe the methods of preparation of the fecal microbiota transplantation in the treatment of the recurrent infections with C. difficile and the interactions to consider for hospital pharmacies that do not have technical means to operate this technique.
