Filter by:This study is planned to reveal the microbiological agents and drug sensitivities to these agents in patients diagnosed with chronic suppurative otitis media who complain of ear discharge.
The microbiome acts as an antigen and can induce signaling through receptors like TLRs and NODs. Microbial metabolites can directly act on gut cells or reach other organs systemically. Studies show that the commensal, non-pathogenic microbiota plays an important role in regulating the immune system in various ways: - Promoting differentiation of Th17 cells and ILC3 signaling to regulate IL-17A production - Influencing iNKT cell generation early in life to prevent inflammatory activities - Facilitating CD4+ T cell differentiation and balancing Th1/Th2 responses - Inducing regulatory T cells (Tregs) that promote immune homeostasis - Tregs in Peyer's patches help maintain a microbiome that supports homeostasis The microbiome influences T cells, B cells and immune homeostasis. This has implications for transplantation, where modulating the microbiome could impact the graft's acceptance by affecting the recipient's immune cells that respond to the transplant. In summary, it highlights the microbiome's role in immune regulation and the potential for leveraging this interaction therapeutically, including in the context of transplantation.
The FEEDMe Study is a single-group, open label pilot study exploring how diverse, commercially available foods rich in arabinose influence the gut microbiome in adults from diverse populations.
The goal of this observational study is to classify patients that undergo pancreatic resection for presumed pancreatic or periampullary malignancy into high and low risk groups for postoperative complications based on longitudinal saliva, rectal/faecal, tumor, blood and/or bile microbiome profiles. To identify the dynamics of the microbiome, as well as the possibly related short-term and long-term complications, multiple samples at different timepoints are needed from the patients.
This study aims to determine whether a parent-to-child nasal microbiota transplant (NMT) can seed and engraft parental organisms into the neonatal microbiome and increase the neonatal microbiome diversity.
This study aims to develop a therapy for restoring the gut microbiome in infants born via CS. We will conduct a randomized, placebo-controlled feasibility trial to assess the ability of microbiome restoration by FMT and FVT in infants born by cesarean section.
In this clinical trial, our aim is to assess the effect of auto-FMT (Fecal microbiome transplantation) on the intestinal microbiota, after a course of antibiotics. 30 healthy adults are recruited. All are given a five day course of amoxicillin-clavulanate. The subjects are double blinded and randomized to two groups. Group A is given autologous FMT (auto-FMT) on day 7 (two days after the end of the course of antibiotics) and Group B is given auto-FMT on day 28 (23 days after the end of the course of antibiotics).
The goal of this clinical trial is to study if a oral maternal fecal transplant given to a premature infant born by cesarean section (CS) is safe. The investigators will also compare the gut microbiome of the infants to those born by CS and not received the transplant and to premature infants born vaginally.
ARO-DECAMP is a multi-centre, placebo-controlled, pilot and feasibility randomized controlled trial for the microbial consortium Microbial Ecosystem Therapeutic-2. Non-intensive care unit patients ≥ 18 years old diagnosed with a bloodstream infection and receiving treatment for an antibiotic resistant organism will be included. Participants will be randomized to receive either MET-2 or placebo for 10 days. Recruitment rate and study intervention adherence will be evaluated for feasibility. Participants will be followed for 180 days, and biological samples will be collected periodically for clinical, ecological, and biomarker outcomes.
The objective of this novel study is to establish proof of concept using a pilot randomized controlled trial to determine the effect of DHM compared to formula supplementation on the microbiome in full-term infants who are born via caesarean section and require supplementation. Secondarily, this study aims to compare the infant health outcomes of sleep and growth between groups to assess if these outcomes are mediated by infant feeding type or potential differences in microbial signatures. Finally, this study will compare maternal outcomes of depression, anger, breastfeeding self-efficacy and breastfeeding rates between groups. The infant gut microbiome plays a critical role in the developing immune, neurologic, and endocrine systems. Yet, most infants experience early life disruptions (ELDs) to their microbiome that have potential long-term health and development impacts. A major source of disruption is caesarean section (c-section) delivery because the infant is born surgically and is not exposed to important commensal bacteria required to establish the infant microbiome. Currently in Canada, over 28% of infants are born via c-section. Exclusive breastfeeding can improve gut microbiota composition in infants who are born via c-section. However, approximately 60% of infants born via c-section require formula supplementation in their first week of life. Evidence indicates that even one bottle of formula can further disrupt the gut microbiome. Donor human milk (DHM) is a superior alternative to formula when supplementation is required as its biotic properties minimize perturbations to the infant gut microbiome and may help to repair the microbiome in infants who experience ELDs. Yet, while DHM is well researched in preterm populations, evidence on the impact of DHM as a therapeutic intervention on the full-term infant gut microbiome is lacking. The hypothesis of this study is: that replacing formula with DHM supplementation will minimize gut microbiome dysbiosis and foster homeostasis following supplementation. In addition, it is hypothesized that improved homeostasis will promote improved sleep and growth outcomes in participant infants. Finally, mothers whose infants receive DHM will have lower depression and anger scores and higher breastfeeding self-efficacy and exclusive breastfeeding rates compared to mothers whose infants receive formula.
