[PMID: 38155743 PMCID: PMC10753978 DOI: 10.2147/dddt.s443462] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/06/2023] [Accepted: 12/13/2023] [Indexed: 12/30/2023] Open
Abstract
Dysregulation of the gut microbial ecosystem (GME) (eg, alterations in the gut microbiota, gut-derived metabolites, and gut barrier) may contribute to the onset and progression of extra-intestinal diseases. Previous studies have found that Traditional Chinese Medicine herbs (TCMs) play an important role in manipulating the GME, but a prominent obstacle in current TCM research is the causal relationship between GME and disease amelioration. Encouragingly, co-housing and fecal microbiota transplantation (FMT) provide evidence-based support for TCMs to treat extra-intestinal diseases by targeting GME. In this review, we documented the principles, operational procedures, applications and limitations of the key technologies (ie, co-housing and FMT); furthermore, we provided evidence that TCM works through the GME, especially the gut microbiota (eg, SCFA- and BSH-producing bacteria), the gut-derived metabolites (eg, IS, pCS, and SCFAs), and intestinal barrier to alleviate extra-intestinal diseases. This will be beneficial in constructing microecological pathways for TCM treatment of extra-intestinal diseases in the future.

Abstract
Dysregulated immune system with a failure to recognize self from non-self-antigens is one of the common pathogeneses seen in autoimmune diseases. The complex interplay of genetic and environmental factors is important for the occurrence and development of the disease. Among the environmental factors, disturbed gut microbiota (gut dysbiosis) has recently attracted particular attention, especially with advancement in human microbiome research. Although the alterations in microbiota have been seen in various autoimmune diseases, including those of nervous system, there is paucity of information on neuromuscular system diseases. Myasthenia gravis (MG) is one such rare autoimmune disease of neuromuscular junction, and is caused by generation of pathogenic autoantibodies to components of the postsynaptic muscle endplate. In the recent years, accumulating evidences have endorsed the key role of host microbiota, particularly those of gut, in the pathogenesis of MG. Differential microbiota composition, characterized by increased abundance of Fusobacteria, Bacteroidetes, and Proteobacteria, and decreased abundance of Actinobacteria and Firmicutes, has been seen in MG patients in comparison to healthy subjects. Disturbance of microbiota composition, particularly reduced ratio of Firmicutes/Bacteroidetes, alter the gut permeability, subsequently triggering the immunological response. Resultant reduction in levels of short chain fatty acids (SCFAs) is another factor contributing to the immunological response in MG patients. Modulation of gut microbiota via intervention of probiotics, prebiotics, synbiotics, postbiotics (metabiotics), and fecal microbiota transplantation (FMT) is considered to be the futuristic approach for the management of MG. This review summarizes the role of gut microbiota and their metabolites (postbiotics) in the progression of MG. Also, various bacteriotherapeutic approaches involving gut microbiota are discussed for the prevention of MG progression.

Abstract
Fecal microbiota transplantation (FMT), also known as fecal bacterial therapy, is a treatment option that can quickly reconstruct the normal composition of intestinal microbes, and it has a good therapeutic effect on Clostridium difficile infection, as well as on other microecological disorders. However, the causal mechanism of FMT efficacy remains to be clarified, its safety is a major problem, and the standardization and acceptability of FMT need to be improved. This review summarizes its current research status and potential research areas that need to be strengthened, and proposes to clarify the safety of FMT and the causal relationship between FMT and therapeutic effectiveness based on germ-free animals. Meanwhile, the research system is combined with multiomics technology to screen the effective bacteria in FMT, and develop standard, safe, effective and controllable flora of FMT.

Abstract
Universal stool banks rely on, but face difficulties recruiting, community volunteers to donate stool for faecal microbiota transplantation (FMT) to effectively treat recurrent Clostridioides difficile. This study sought to identify determinants of community members' willingness to donate stool to guide donor recruitment. 397 Australian residents (52% male, 47% 21-30 years, 63% university educated) completed a survey to gauge willingness to donate stool, bowel habits, information needs, attitudes, barriers, and motives for donation. Most reported regular bowel movements (BMs; 90%), morning BMs (63%), BMs ≤5 minutes duration (67%), and some discomfort doing BMs in public restrooms (69%). Less than half were willing to donate stool in-centre (45% willing) or at home (48%). Important information needs identified by >80% were convenience and travel requirements associated with donation. Main barriers were logistics, capabilities to donate, disgust (e.g., donation process), and discomfort (e.g., privacy). The main motivator was altruism, with compensation secondary. Linear regression models identified less discomfort doing BMs in public restrooms (β = -0.15), understanding benefits to patients (β = 0.15), placing less importance on understanding the donation process (β = -0.13), and positive attitudes (β = 0.56) as determinants of willingness to donate in-centre. Understanding benefits to self (β = 0.11) and patients (β = 0.24), placing less importance on understanding the donation purpose (β = -0.19), and positive attitudes (β = 0.50) determined willingness to donate at home. Stool banks should consider donor's bowel habits, comfort donating in-centre, and information needs early in recruitment; and implement flexible logistics for potential donors who face time constraints and limited access to stool banks.

Hyde MK, Masser BM. Eligible blood donors' decisions about donating stool for fecal microbiota transplantation: Does ambivalence play a role? Transfusion 2020; 61:474-483. [PMID: 33006187 DOI: 10.1111/trf.16109] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/29/2020] [Revised: 09/11/2020] [Accepted: 09/11/2020] [Indexed: 12/22/2022]
Abstract
Blood collection agencies (BCAs) are expanding core business by inviting blood donors to donate stool for fecal microbiota transplantation (FMT). However, whether blood donors also want to donate stool is unclear since, despite its benefits, stool donation is viewed by many as unpleasant. This study examined the prevalence, contributors to, and role of these mixed feelings (ambivalence) in stool donation intentions. STUDY DESIGN AND METHODS This cross-sectional study surveyed Australian residents aged 18 years or more who believed themselves eligible to donate blood and met broad criteria for prescreening as a stool donor (eg, healthy, not taking medication). Survey questions assessed attitude, norms, self-efficacy, motives, disgust, ambivalence, and intentions to donate stool. RESULTS A total of 382 eligible blood donors aged not more than 50 years (mean, 28.71 years; 48% female, 62% "healthy" body mass index) participated. Six percent indicated no ambivalence about donating stool. In regression, significant determinants of ambivalence were less awareness of FMT, lower self-efficacy, motivated by ensuring that stool is available for loved ones, and more disgust about stool donation. Higher ambivalence contributed to decreased donation intention. Self-efficacy and disgust differentiated participants with moderate ambivalence, a group likely responsive to intervention, from those with low or high ambivalence. CONCLUSION Ambivalence about donating stool was common among eligible blood donors. BCAs should raise awareness about stool donation and FMT before requesting donation. BCAs may increase cost savings and donor retention by giving clear guidance about donation requirements and implementing processes that build confidence. Early screening of potential donors for ambivalence and disgust will enable BCAs to provide decision support.

Abstract
The rapid development of metagenomics, metabolomics, and metatranscriptomics provides novel insights into the intestinal microbiota factors linked to inflammatory bowel disease (IBD). Multiple microorganisms play a role in intestinal health; these include bacteria, fungi, and viruses that exist in a dynamic balance to maintain mucosal homeostasis. Perturbations in the intestinal microbiota disrupt mucosal homeostasis and are closely related to IBD in humans and colitis in mice. Therefore, preventing or correcting the imbalance of microbiota may serve as a novel prevention or treatment strategy for IBD. We review the most recent evidence for direct or indirect interventions targeting intestinal microbiota for treatment of IBD in order to overcome the current limitations of IBD therapies and shed light on personalized treatment options.

Abstract
Worldwide, there is a rising demand for thoroughly screened, high-quality fecal microbiota transplantation (FMT) products that can be obtained at a reasonable cost. In the light of this evolving therapeutic area of the intestinal microbiota, both private and public stool banks have emerged. However, some of the larger difficulties when establishing stool banks are caused by the absence of or international disagreement on regulation and legislative formalities. In this context, the establishment of a stool bank within a nonprofit blood and tissue transplant service has several advantages. Especially, this setting can ensure that every step of the donation process, laboratory handling, and donor-traceability is in agreement with the current expert guidelines and meets the requirements of the European Union's regulative directives on human cells and tissues. Although safety and documentation are the top priority of the stool bank setup presented here, cost-effectiveness of the production is possible due to a high donor screening success rate and the knowhow, infrastructure, facilities, personnel, and laboratory- and quality-management systems that were already in place. Overall, our experience is that a centralized, nonprofit, blood and tissue transplant service is an ideal and safe facility to run a stool bank of high quality FMT products that are based on stool donations from volunteer, unpaid, healthy, blood donors.

Abstract
BACKGROUND Fecal microbiota transplantation (FMT) has become an emergent method in the therapy of several intestinal diseases, mainly in Clostridium difficile recurrence. The training of FMT in medical schools is at its beginning and in countries where FMT is only occasionally carried out, it is important to know the perception of medical students on FMT. METHODS We undertook a survey of 3rd year medical students not exposed to official academic information on FMT in order to find out their knowledge, beliefs and attitude toward FMT. A number of 80 students were asked to fill a dedicated online questionnaire. RESULTS 52 out of 80 third year medical students anonymously filled the questionnaire (65% response rate). 34% of respondents reported to have at least a medium level of knowledge regarding FMT. The top indication for FMT identified by 76.9% was C. difficile infection; however, 60% believed FMT to be a promising therapy for a high number of conditions and while almost all respondents (98.1%) would recommend it, 88.4% would explore other options first. Colonoscopy was considered the optimal method of delivery by 42.3%. Only 39% of participants believed that patients would accept FMT, however 71% considered that a more socially acceptable name for the procedure and anonymous donors would increase acceptance rate. The risk of transmitting a disease undetected by donor stool screening procedures to the recipient was the most worrying side effect considered by 75% of respondents. 54% believed that more research is required for FMT to enter clinical practice and 55.7% of respondents would enroll patients in controlled clinical trials. CONCLUSIONS Medical students not exposed to educational information on FMT seem to be somewhat well informed about this method and would recommend it to their patients. Students, however, need to know more on the indications of FMT.
