[Fecal microbiota transplantation]

Area of Science:

• Microbiology
• Gastroenterology
• Immunology

Background:

• The human intestinal microbiome plays crucial roles in host metabolism, immunity, and pathogen defense.
• Factors like antibiotics, probiotics, diet, and fecal microbiota transplantation (FMT) significantly influence the gut microbiome.
• FMT involves transferring fecal matter from a healthy donor to a patient to restore a balanced microbiome.

Purpose of the Study:

• To explore the therapeutic potential of FMT in various diseases linked to microbial dysbiosis.
• To highlight FMT as a highly effective treatment for recurrent Clostridium difficile infections (CDI).
• To identify areas requiring further investigation, including optimal donor selection, dosage, and administration routes for FMT.

Main Methods:

• Fecal microbiota transplantation (FMT) procedure involving the transfer of fecal microorganisms.
• Clinical evaluation of FMT efficacy in patients with recurrent Clostridium difficile infections.
• Review of current and potential future therapeutic applications of FMT.

Main Results:

• FMT achieves approximately 85% success in treating recurrent Clostridium difficile infections, significantly outperforming conventional vancomycin treatment (around 30%).
• Potential therapeutic applications for FMT in chronic inflammatory and functional bowel diseases, insulin resistance, and morbid obesity require further clinical trials.
• Limited knowledge exists regarding optimal donor selection, dosage, and administration routes for FMT.

Conclusions:

• FMT is a highly effective treatment for recurrent Clostridium difficile infections.
• Further clinical trials are essential to validate FMT's efficacy for other conditions.
• Standardization of FMT protocols, including donor selection and administration, is crucial for its broader clinical implementation and long-term safety evaluation.
