Summary
Fecal microbiota transplantation (FMT) studies often lack crucial methodological details for replication and understanding efficacy. Key components of FMT interventions are poorly reported in published research.
Area of Science:
- Gastroenterology and Hepatology
- Microbiology
- Clinical Research Methodology
Background:
- Fecal microbiota transplantation (FMT) is a potential novel therapy for chronic diseases linked to gut dysbiosis.
- Research is exploring FMT's role beyond its established use in Clostridium difficile infection.
Purpose of the Study:
- To critically evaluate the methodology and reporting standards of clinical studies investigating fecal microbiota transplantation (FMT).
- To identify gaps in the reporting of essential FMT intervention components.
Main Methods:
- Systematic review of English-language human clinical studies on FMT safety or efficacy.
- Searches conducted across major databases (PubMed, EMBASE, Web of Science, Cochrane).
- Independent assessment of study characteristics and reporting of methodological elements by multiple reviewers.
Main Results:
- Most studies (84%) focused on Clostridium difficile infection or inflammatory bowel disease, predominantly using non-randomized designs (87%).
- Significant reporting deficiencies were noted in donor eligibility (47%), stool collection materials and timing (96%), stool conservation methods (76%), stool type/amount (not specified), and conservation duration (67%).
- Microbiota composition analysis was absent in 58% of studies.
Conclusions:
- A lack of consensus on critical FMT methodological components hinders study assessment and reproducibility.
- Poor reporting of key FMT intervention details compromises the ability to understand and replicate study findings on efficacy and safety.

01:50What is Monogastric Digestion?
The human body contains a monogastric digestive system. In a monogastric digestive system, the stomach only contains one chamber in which it digests food. Several other animal species also have monogastric digestive systems, including pigs, horses, dogs, and birds. This chapter, however, focuses on the human digestive system.
01:30Methods to Assess Microbial Populations
Assessing microbial populations is crucial for understanding microbial roles in health, ecology, and industry. Various complementary techniques—both culture-based and molecular—enable detailed analysis of microbial abundance, diversity, and function.Viable Plate CountThe viable plate count is a traditional culture-based method used to estimate the number of living microbes in a sample. After serial dilution, the sample is spread onto nutrient agar plates. Each viable cell forms a visible...
01:19Methods to Assess Microbial Communities
Microbial communities, comprising bacteria, archaea, and eukaryotic microorganisms, inhabit diverse ecosystems and play crucial roles in environmental and biological processes. Their diversity is defined by three main parameters: species richness (the number of distinct species), species abundance (the relative quantity of each species), and species evenness (how uniformly individual species are distributed in various locations). These factors together shape the structure and ecological balance...
01:18Dysbiosis of the Gut Microbiota
The human gut microbiome includes a diverse array of microbial species, including beneficial commensals and opportunistic pathogens, which interact to support host health. These microbes contribute to essential functions such as nutrient metabolism, immune system modulation, and maintenance of intestinal barrier integrity. However, disruptions to this equilibrium—referred to as dysbiosis—can have widespread physiological consequences.Dysbiosis is often characterized by reduced microbial...
01:21Microbiota Modulation by Antibiotics
Antibiotics have revolutionized modern medicine by saving countless lives from bacterial infections. However, their widespread use has inadvertently harmed the delicate balance of the human gut microbiota. The gut microbiota, a complex community of bacteria, archaea, viruses, and fungi, plays a vital role in regulating metabolism, immune responses, and maintaining intestinal health. Antibiotics, especially broad-spectrum types, disrupt this ecosystem by eradicating both harmful and beneficial...
