Active clinical trials for "Dysbiosis"

The investigators propose to use autologous fecal microbiota transplantation (AFMT) to acute myeloid leukemia (AML) patients treated with intensive chemotherapy and antibiotics in order to restore the balance of their intestinal microbiome and thereby eradicate treatment-induced multidrug resistant bacteria (MDRB), infection-related complications, as well as sequelae to the gastrointestinal tract. Therefore, the investigators propose to perform a single-arm multicentre prospective fecal microbiota transplantation (FMT) trial in AML patients receiving intensive chemotherapy, and who are usually heavily treated with broad-spectrum antibiotics during aplasia that generate a profound status of dysbiosis. For this purpose, at the time of admission and AML diagnosis, patients will be requested to donate stools that will be comprehensively screened, and if deemed appropriate according to protocol criteria, conditioned and stored frozen until future processing and transplantation after aplasia completion.

This study evaluates the relationship of endocannabinoids in saliva with inflammation and oral dysbacteriosis present in people with periodontal disease and prediabetes/type 2 diabetes

The double-blinded placebo-controlled study compares the effect of fecal microbiota transplantation vs. Anaerobically Cultivated Human Intestinal Microbiota (ACHIM) or placebo (own feces) on manipulating the gut microbiota in patients with diarrhea-predominant irritable bowel syndrome (IBS).

This study will investigate the link between the gut microbiota, the occurrence of the central adiposity phenotype, and the patients' fear to regain weight in anorexia nervosa.

The gut microbiome is a complex ecosystem with a wide range of functions, and it is thought that it can influence multiple processes in the human body. In turn, the composition and activity of the gut microbiome is affected by many factors as well. Antibiotics can be very effective in treating bacterial infections, but they are also associated with detrimental health effects. Previous studies have already shown that antibiotics disturb the human gut microbiome composition by destroying commensal bacteria. As it is well known that the microbiome influences host metabolism, perturbation of the healthy microbiome (dysbiosis) is thought to be disease causing. Prebiotics, on the other hand, are beneficial for the gut microbiome. These so-called indigestible fibers are naturally present in our foods, but cannot be metabolised by the human body. Many bacteria in the human gut are able to ferment these fibers and they subsequently produce beneficial products for the rest of the body. Besides this, fiber intake stimulates growth of commensal bacteria in the human gut. Although it has become increasingly clear that prebiotics have a beneficial effect on the gut microbiome and general health, it is still unclear to which extent the beneficial effects of prebiotics supplementation occur after the gut microbiome is disturbed by antibiotics. We hypothesize that prebiotic supplementation after antibiotics use will improve restoration of the gut microbiome to a healthy state compared to placebo.

This study is aimed to manipulate the composition of the intestinal flora of the infants born by caesarian section through the administration of the probiotic strain "Bifidobacterium bifidum PRL 2010", in order to evaluate its effects on gut dysbiosis during the first 6 month of life.

Prospective interventional study of the effect of PPI on the duodenal microbiome in healthy volunteers and functional dyspepsia patients

Single-site prospective interventional study aiming to demonstrate the effect of spore-forming probiotics on dyspeptic symptoms and blood, saliva and stool parameters in FD patients with and without acid suppression, compared to placebo.

A randomized, double-blind, placebo-controlled, cross-over trial performed at one centre in Italy to explore the ability of a multistrain probiotic mixture, to modulate markers of inflammation and intestinal barrier function and gastrointestinal symptoms in healthy volunteers with self-reported anxiety.

Vaginal dysbiosis is a common condition among women. Vaginal dysbiosis covers imbalances in the vaginal flora, caused by the composition of microbes, bacteria, viruses and fungi. Dysbiosis occurs in about 16% of all women in Denmark. A large proportion of women who have vaginal dysbiosis do not experience any symptoms. However, vaginal dysbiosis can present challenges in several contexts, including a higher tendency for bacterial infections in the female genitals, lower chances of pregnancy in women undergoing fertility treatment, just as it can predispose to premature birth. This project is aimed at women aged 18-40, who wants to participate in a study to investigate whether, by transplanting vaginal secretion from one woman with a normal vaginal bacterial flora to another woman with an imbalance in the vaginal bacterial flora (called vaginal dysbiosis), can establish a normal vaginal bacterial flora in the recipient of the transplant. The study will also explore weather genetic, immunological, hormonal, metabolic, health behaviors and clinical factors have significance on whether a normal vaginal flora is achieved after transplantation.
