Study Notes

Fecal Microbiota Transplantation (FMT)

  • FMT is the infusion of stool from a healthy individual to a recipient with a presumed gut microbiome imbalance.
  • It aims to restore normal gut function through the establishment of a new gut microbiota community.
  • Successfully used for recurrent Clostridium difficile infection (rCDI).
  • Potential applications in other gastrointestinal disorders, inflammatory bowel disease (IBD), autoimmune disorders, allergies, and metabolic conditions (e.g., obesity).
  • Short-term success in rCDI leads to investigation in other conditions.

Key Barriers

  • Determining characteristics of a healthy microbiome
  • Ensuring recipient safety and long-term outcomes
  • Adequate recipient monitoring of fecal material
  • Quality control
  • Maintaining reasonable costs
  • Establishing uniform protocols for stool preparation
  • Selecting best FMT administration modes
  • Maintaining large databases of donors and recipients
  • Ensuring oral ingestion equivalence to colonoscopic infusion

Indications

  • Recurrent Clostridium difficile infection (rCDI)
  • Inflammatory bowel disease (IBD)
  • Autoimmune disorders
  • Allergies
  • Metabolic disorders (e.g., obesity)
  • Irritable bowel syndrome (IBS)
  • Non-alcoholic steatohepatitis (NASH)
  • Hepatic encephalopathy

Recipient Considerations

  • Viral hepatitis, HIV, and syphilis screenings recommended pre-FMT.
  • Donor screenings are crucial to minimize infection or disease transmission risk (thorough history taking, serological and fecal tests).

Donor Selection

  • Rigorous screening process to minimize infection or disease transmission risk.
  • Exclusion criteria include age (<18 or >65), BMI (>30 kg/m²), metabolic syndrome, etc.

Procedure and Patient Management

  • Antibiotics often administered for at least 3 days before FMT.
  • Bowel preparation (enemas or omitted in severe ileus) recommended with colonoscopy.
  • Standardized protocols for stool and FMT preparation.
