Fecal microbiota transplantation (FMT), also called stool transplantation, is a process during which stool from a wholesome donor is positioned into the intestine of a affected person in an effort to deal with a sure illness. FMT shouldn’t be a brand new idea, however within the final six years it has change into a standard-of-care remedy for the therapy of recurrent Clostridium difficile an infection (CDI).
Treating an infection with C. difficile
Clostridium difficile (C. diff) is a bacterium that’s ever-present in our surroundings.

The principle danger issue for CDI is taking antibiotics, which is why docs discourage pointless antibiotic use. Paradoxically, first-line therapy for CDI can also be antibiotics. About 20% of individuals handled with antibiotics will develop recurrent infections, and one of the simplest ways of clearing recurrent CDI is with FMT. That is supported by a number of pointers. The explanation why FMT works so effectively is essentially unknown, however typically talking it restores essential useful micro organism that assist defend towards CDI.
However whereas supported by pointers, FMT continues to be thought of investigational and isn’t presently FDA-approved. Nevertheless, FMT will be carried out for scientific care to deal with recurrent CDI (sometimes outlined as three or extra confirmed episodes), or CDI that doesn’t reply to different remedies. An FMT for every other indication can solely be carried out within the setting of a scientific trial.
How is FMT carried out?

The donor stool is screened for doubtlessly disease-causing organisms; the donor’s blood undergoes routine laboratory testing and is screened for infectious ailments; and the donor’s medical historical past is evaluated.
How effectively does FMT work?
FMT has a treatment fee of 80% to 90%, which means the overwhelming majority of sufferers will probably be cured of recurrent CDI with a single therapy. Nevertheless, there are some sufferers who will want a couple of FMT therapy.
The window of recurrence is usually eight weeks; if a affected person makes it to eight weeks post-FMT with none points or recurrence of diarrhea, we deem them cured. We don’t have a great way of predicting who may fail their first FMT. However we do know that antibiotics inside the first eight weeks post-procedure needs to be averted if potential.
General, FMT is a protected, effectively tolerated, and presumably lifesaving process for recurrent CDI. FMT shouldn’t be tried at house, however slightly ought to solely be carried out by a educated clinician utilizing totally screened materials.
