Fecal Microbiota Transplantation: Indications, Methods, and Challenges

Area of Science:

• Microbiology
• Gastroenterology
• Immunology

Background:

• The gut microbiota's role in human health is increasingly recognized.
• Fecal microbiota transplantation (FMT) has a long history, evolving from ancient practices to modern medicine.
• FMT is a standard treatment for recurrent Clostridioides difficile infections due to its high efficacy.

Purpose of the Study:

• To review the mechanisms, clinical indications, methods, and challenges of current FMT.
• To explore the potential of FMT for diseases beyond C. difficile infections.
• To discuss alternative therapies addressing FMT challenges.

Main Methods:

• Review of existing literature on fecal microbiota transplantation.
• Analysis of historical and current clinical applications of FMT.
• Discussion of various FMT formulations and administration routes.

Main Results:

• FMT is highly effective for recurrent C. difficile infections.
• Preliminary results show promise for FMT in other diseases.
• Various FMT methods and delivery routes have been developed.

Conclusions:

• FMT is a valuable therapeutic option, particularly for C. difficile.
• Further research is needed to overcome challenges in donor screening, manufacturing, and understanding FMT components.
• Development of alternative therapies is crucial for advancing FMT applications.
