Filter by:There are several studies performed to reveal the linkage between diet, fecal microbiota, and obesity. Human fecal microbiota transplantations in this asset are still scarce. Therefore, this pilot study of FMT from lean to obese people with dietary counseling will increase the knowledge, whether FMT could play a role in the treatment of obesity and NAFLD. Our primary outcome is the changes in glucose metabolism by HOMA-IR.
In the 21st century, the incidence of inflammatory bowel disease (IBD) globally increases. Higher incidence of IBD development may implicate that environmental factors played essential roles in IBD pathogenesis. One of the environmental factors is a westernized diet that contains a high amount of animal protein and a low amount of dietary fiber. This kind of diet can lead to gut microbial dysbiosis and increase susceptibility to IBD. A microbial dysbiosis pattern in IBD is a decrease in microbial diversity and the inversed ratio of local protective and pathologic bacteria. High animal protein was associated with an increased risk of IBD and increased risk of disease relapse meanwhile dietary fiber was associated with IBD risk reduction. A semi-vegetarian diet is a diet with high fiber and low red meat and processed food that may reduce inflammatory activity in IBD. The study in the semi-vegetarian diet in IBD activity is still limited. This study aimed to evaluate a semi-vegetarian diet's effect in maintaining IBD remission in disease quiescence patients.
Incidence of digestive neuroendocrine tumors are increasing. Analysis of individual microbiota is a way to explore new neoplastic mechanisms, tumor identification and therapeutic orientations. This prospective pilot study aims to describe fecal bacterial phylogeny of patients with digestive neuroendocrine tumor. Bacterial genomic signature will be recorded at initiation of Lanreotide treatment in naive patient with digestive neuroendocrine tumor (pancreas or small intestine), metastatic or locally advanced, as well as after one year follow up.
This is an open-label study evaluating the safety and efficacy of CP101 treatment in 1) Subjects in CDI-001 who had a CDI recurrence within 8 weeks of receiving CP101 or placebo; OR 2) adults with recurrent CDI who are eligible for direct study entry into CP101-CDI-E02. Subjects who are experiencing recurrent CDI will undergo screening procedures. Subjects who meet eligibility criteria will be eligible to be enrolled in he study and administered CP101. Approximately 200 subjects will receive CP101. The treatment duration will be 1 day. Subjects will be monitored for recurrence of CDI, safety, and tolerability for 24 weeks following receipt of CP101. The primary efficacy and safety endpoints will be evaluated at 8 weeks post treatment, and all subjects will continue to be followed for an additional 16 weeks for safety and recurrence of CDI.
Composition and diversity of intestinal microbiota that are subject to the influence of diet have a significant impact on health in the gut and whole body via complex interactions between food constituents, bacteria, and host. Polyphenols are poorly absorbed in the upper gastrointestinal tract and reach the colon, where they may have a reciprocal relationship with microbiota. Because how polyphenols mediate gut health and reduce risk for other pathogenesis remains to be elucidated, we propose to conduct a pilot controlled feeding study to examine the impact of polyphenols and other constituents in the free dried whole cranberry powder (FWCP) on composition and diversity of gut microbiota, as well as to substantiate bioavailability of cranberry polyphenols. The central hypothesis underlying the proposed research is that FWCP polyphenols will diminish the magnitude of a plant food free diet induced increase in Alistipes, Bilophila and Bacteroides and will increase Enterococcus, Bifidobacterium, Eggerthella lenta, and Blautia coccoides-Eubacterium rectale groups. The proposed research is novel as no study has examined the specific impact of FWCP polyphenols incorporated into a plant food free diet on gut microbiota. This proposed study is innovative because the positive results will demonstrate with a high degree of confidence that the impact of FWCP constituents on production of beneficial short chain fatty acids, carcinogenic bile acids, and atherogenic trimethylamine. The results generated from the study using a plant food free dietary regimen as the background diet will provide definite proof on microbial modulating actions of FWCP, inform mechanism of actions in urinary tract infection (UTI), and be used to formulate messages in consumer communications for gut health.
This clinical trial will evaluate the stool of infants fed one of two infant formulas, which contain different types of proteins, or breast milk to determine if different proteins have an effect on the type of bacteria that enters and lives in an infant's intestine early in life.
