Human microbiome: From the bathroom to the bedside.

Area of Science:

• Microbiology
• Gastroenterology
• Immunology

Background:

• The human gut microbiome comprises trillions of bacteria, with major phyla including Bacteroidetes, Firmicutes, Actinobacteria, and Proteobacteria.
• Fecal microbial transplantation (FMT) is a long-established procedure that has recently undergone rigorous scientific evaluation.
• The gut microbiota plays a crucial role in maintaining host health and is implicated in various gastrointestinal disorders.

Purpose of the Study:

• To review the current evidence supporting the efficacy of FMT for specific gastrointestinal conditions.
• To assess the established and emerging indications for FMT.
• To identify areas requiring further research in FMT application and delivery.

Main Methods:

• A comprehensive review of existing scientific literature and clinical studies on FMT.
• Analysis of data pertaining to FMT's effectiveness in treating recurrent Clostridium difficile infection.
• Examination of preliminary evidence for FMT in irritable bowel syndrome and inflammatory bowel disease.

Main Results:

• FMT is an approved and effective treatment for recurrent Clostridium difficile infection.
• There is emerging evidence suggesting potential benefits of FMT for irritable bowel syndrome.
• Preliminary data indicates possible efficacy of FMT in managing inflammatory bowel disease, though further investigation is warranted.

Conclusions:

• Fecal microbial transplantation has demonstrated clear efficacy and is an approved therapy for recurrent Clostridium difficile infection.
• Further research is essential to fully elucidate the therapeutic potential of FMT for irritable bowel syndrome and inflammatory bowel disease.
• Defining optimal FMT protocols, including indications and administration methods, is a critical next step for clinical implementation.
