Fecal Bacteriotherapy, also called fecal microbiota transplantation (FMT) involves the infusion of intestinal microorganisms via transfer of stool from a healthy individual into a diseased individual, with the intent of restoring normal intestinal flora. Fecal transplant is proposed for the treatment of treatment-refractory Clostridioides (previously Clostridium) difficile infection (CDI).
The US Food and Drug Administration (FDA) has classified human stool as a biological agent and determined that its use in fecal microbiota transplantation (FMT) therapy and other research should be regulated to ensure patient safety.
Fecal transplantation is usually performed by colonoscopy and less commonly by nasoduodenal tube. During colonoscopy the colonoscope is advanced through the entire colon. As the colonoscope is withdrawn, the donor stool is delivered through the colonoscopy into the colon.
Current guidelines state that the preferred route of administration of FMT is colonoscopy due to risk for aspiration and long-term bacterial overgrowth in the small intestine following NG or enteroscopy administration.
The goal of FMT is to replace damaged and/or disordered native microbiota with a stable community of donor microorganisms. The treatment is based on the premise that an imbalance in the community of microorganisms residing in the gastrointestinal tract (i.e., dysbiosis) is associated with specific disease states, including susceptibility to infection.
OpenBiome has collaborated with Finch Therapeutics to develop CP101, a freeze-dried oral FMT capsule.
Food and Drug Administration (FDA)
In July 2013, the U.S. Food and Drug Administration (FDA) issued guidance regarding investigational new drug requirements for use of fecal microbiota transplant to treat CDI not responsive to medication therapy. The document states that FDA is continuing to consider how to regulate fecal microbiota transplant and that, during this interim period, the agency will use enforcement discretion regarding use of fecal transplant to treat treatment-resistant CDI infections. FDA requires that physicians obtain adequate informed consent from patients or their legal representative before performing the intervention. The FDA is allowing clinicians to treat these patients without completing an Investigational New Drug application (IND). Clinicians must file an IND in order to perform FMT for any other purpose.
Guidelines and Position Statements
The American College of Gastroenterology
The American College of Gastroenterology recommends that FMT should be considered second-line therapy for a third recurrence of CDI.
American Gastroenterological Association (AGA)
AGA Clinical Practice Guidelines on the Management of Mild-to-Moderate Ulcerative Colitis
In patients with mild–moderate ulcerative colitis (UC) without Clostridium difficile infection, the AGA recommends fecal microbiota transplantation be performed only in the context of a clinical trial.
Infectious Diseases Society of America (IDSA) and Society for Healthcare Epidemiology of America (SHEA)
In 2018, IDSA and SHEA updated the 2010 clinical practice guidelines for the diagnosis and treatment of clostridium difficile infection in adults and children. The Societies recommended pharmacotherapy using vancomycin, fidaxomicin, and/or metronidazole depending on the episode and the severity of the C difficile.
The guidelines strongly recommended fecal microbiota transplantation (FMT) as a treatment option for adults following an initial treatment of CDI and two recurrences (i.e. after three treated CDI episodes) that have been non-responsive to at least two regimens of antibiotics (i.e., various combinations of vancomycin, fidaxomicin, and/or metronidazole). Similar recommendations are made for children but the strength of the recommendations is low and the quality of evidence is low for pharmacotherapy and very low for FMT.
The Societies recommendations for the treatment of C. difficile included the following:
- Initial episodes, non-severe: oral vancomycin (VAN) 125 mg four times a day for ten days; OR oral fidaxomicin (FDX) 200 mg twice a day for ten days; OR if neither VAN or FDX are available, oral metronidazole 500 mg three times a day for ten days.
- Initial episode, severe: oral VAN 125 mg, four time a day for ten days; OR FDX 200 mg twice a day for ten days
- Initial episode, fulminant; 500 mg VAN oral or via NG tube four times a day. If ileus is present consider rectal instillation of VAN. Intravenous metronidazole, 500 mg every eight hours, with VAN if ileus is present.
- First recurrence: VAN 125 mg four times a day for ten days if metronidazole was used for initial episode; OR prolonged tapered and pulsed VAN regimen if a standard VAN regimen was used initially; OR FDX 200 mg twice a day for ten days if VAN was used for the initial episode.
- Second or subsequent recurrence: VAN in tapered and pulsed regimen; OR oral VAN 125 mg four times a day for ten days followed by rifaximin 400 mg three times a day for 20 days; OR FDX 200mg twice a day for 10 days; OR fecal microbiota transplantation (IDSA, 2018).
While the previous guidelines recommended metronidazole as the first-line therapy for initial cases of mild-to-moderate CDI and vancomycin for more severe cases, the new guidelines recommend either vancomycin or fidaxomicin (FDX) as the drug of choice for all initial episodes.
Currently, the use of fecal capsules (oral administration) has been shown to be inferior to upper or lower gastrointestinal infusion (e.g., endoscopy, nasogastric tube, enema, colonoscopy).
Fecal microbiota transplantation/fecal bacteriotherapy may be considered medically necessary in patients >/= 18 years of age when ALL of the following have been met:
- Infection confirmed by a positive stool test for Clostridioides (previously Clostridium) difficile infection
- Treatmet is administered by upper or lower gastrointestinal infusion
- There have been at least 3 episodes of recurrent Clostridioides difficile infection and associated diarrhea refractory to antibiotic therapy including at least one of the following regimens:
- tapered and pulsed vancomycin (VAN) or
- vancomycin (VAN) 125mg four times a day for 10 days followed by rifaximin 400 mg three times a day for 20 days or
- fidaxomicin (FDX) 200mg twice a day for 10 days
- Patient is not immunocompromised, including:
- Patients on major immunosuppressive agents including high-dose corticosteroids, calcineurin inhibitors, mammalian target of rapamycin (mTOR) inhibitors, lymphocyte-depleting biological agents, anti-tumor necrosis factor agents, and others; chemotherapeutic antineoplastic agents.
- Patients with decompensated liver cirrhosis, advanced HIV/acquired immune deficiency syndrome, recent bone marrow transplant, or other cause of severe immunodeficiency
The current studies fail to address and show success with repeated fecal transplants. Therefore, the use of repeat fecal transplant for any indication is considered not medically necessary.
Fecal bacteriotherapy is considered not medically necessary for the first or second episode of clostridium difficile.
Fecal microbiota transplantation/fecal bacteriotherapy is considered investigational for, but not limited to, the following conditions:
- Alopecia Areata
- Crohn’s disease
- Colon Cancer
- D-lactic acidosis
- Diarrhea not associated with Clostridioides difficil
- Graft versus Host Disease or prevention of graft vs host disease
- Insulin resistance
- Irritable Bowel Syndrome
- Inflammatory Bowel Disease
- Mental Health Disorders (e.g. anziety, OCD, autism)
- Metabolic Syndrome
- Multiple Sclerosis
- Neurologic disorders
- Other Autoimmunie Disorders
- Ulcerative Colitis
Recurrent Clostridioides (formerly Clostridium) difficile infection (CDI) is defined by complete abatement of CDI symptoms while on appropriate therapy, followed by reappearance of symptoms within two to eight weeks after treatment has been stopped.
