Fecal transplants as a microbiome-based therapeutic

Area of Science:

• Microbiology
• Gastroenterology
• Immunology

Background:

• Gut microbiome dysbiosis is linked to disease and infection susceptibility.
• Fecal microbiota transplantation (FMT) uses healthy donor feces to restore microbial balance.
• Understanding factors influencing FMT efficacy is crucial for optimizing treatment.

Purpose of the Study:

• To review current knowledge on factors affecting fecal transplant efficacy.
• To explore the impact of host factors (genetics, diet, medications) on FMT outcomes.
• To discuss the transition towards alternative microbiome-based therapies.

Main Methods:

• Literature review of studies on fecal transplant efficacy.
• Analysis of factors associated with successful FMT.
• Examination of emerging microbiome-modulating therapies.

Main Results:

• Microbiome diversity, short-chain fatty acid production, and bile acid conversion correlate with FMT success.
• Bacterial and fungal pathobionts can influence therapy outcomes.
• Host genetics, medications, and diet are recognized as significant, yet understudied, factors.

Conclusions:

• FMT efficacy is influenced by a complex interplay of microbial and host factors.
• Further research is needed to elucidate the role of host-specific elements in FMT success.
• Development of alternative and personalized microbiome therapies is an active area of investigation.
