Fecal Microbiota Transplantation (FMT)

The medical and surgical treatment of hidradenitis suppurativa (HS) remains difficult to date. The search for new therapies for HS is a major challenge. The pathophysiology of HS, the similarities with Crohn's disease and the data in the literature suggest a role for the digestive flora in HS. The role of the intestinal microbiota has now been clearly demonstrated in the pathophysiology of chronic inflammatory bowel disease (IBD), and is suspected in many other diseases. Fecal microbiota transplantation (FMT) is the gold-standard treatment for recurrent Clostridioides Difficile infection, and is being investigated in a wide range of conditions. Our hypothesis is that FMT would improve inflammatory lesions of HS by modifying patients' digestive microbiota. Translated with DeepL.com (free version)

This project is a prospective, multicenter, single-arm, phase II clinical study aimed at evaluating the efficacy and safety of fecal microbiota transplantation (FMT) in treating advanced tumor cachexia.

Chronic constipation is a common gastrointestinal disease with a global prevalence of about 15%, significantly affecting daily life and quality of life. Traditional treatments primarily rely on laxatives, which may lead to adverse effects with prolonged use, while surgical interventions have limited patient acceptance. Recent studies indicate that gut microbiota therapies-including probiotics, prebiotics, synbiotics, postbiotics, and fecal microbiota transplantation (FMT)-can effectively manage chronic constipation. This study aims to investigate the safety and efficacy of FMT combined with a prebiotic nutritional intervention (using a co-localization strategy) in the treatment of functional constipation. Additionally, the investigators will explore changes in fecal microbiota and metabolomic profiles following the treatment.

The goal of this clinical trial is to learn if fecal microbiota transplantation can treat in Gastrointestinal cancer patients with chemotherapy / targeted gastrointestinal symptoms. The main question it aims to answer is: To evaluate the effect of fecal microbiota transplantation (FMT) on gastrointestinal tract in patients with gastrointestinal tumors.

The STOP-CDI study is a multicenter, randomized, open-label, three-arm clinical trial comparing the efficacy of fecal microbiota transplantation (FMT) preceded by vancomycin, fidaxomicin monotherapy, and standard-of-care vancomycin in preventing recurrence of Clostridioides difficile infection (CDI) in high-risk adult patients. CDI is a common healthcare-associated infection with rising incidence and high recurrence rates, particularly in elderly and immunocompromised individuals. While current guidelines recommend fidaxomicin as first-line therapy, its availability and reimbursement remain limited in some healthcare systems. FMT, although effective, is not widely implemented as first-line treatment. This study addresses the need for comparative, real-world data to inform treatment decisions for patients at high risk of severe or recurrent CDI. Eligible participants include adults aged ≥65 years or younger patients with specific risk factors such as multiple comorbidities, prior CDI episodes, recent hospitalization, use of non-CDI antibiotics, or PPI therapy. Participants will be randomized in a 2:1:1 ratio to one of three treatment arms: (1) vancomycin plus FMT, (2) fidaxomicin, or (3) vancomycin alone. FMT is administered via capsules or, if necessary, alternative endoscopic routes. The primary endpoint is CDI recurrence within 12 weeks following the initial treatment. Secondary endpoints include clinical cure, safety, and global cure. Exploratory analyses will assess microbiome changes and potential genomic predictors of response. A total of 424 participants will be enrolled across 10 clinical sites in Poland. The study aims to provide robust, comparative evidence to support clinical guidelines and improve outcomes for patients with CDI, particularly in healthcare systems with limited access to novel therapies.

Autism Spectrum Disorders (ASD), affect approximately 1% of the general population and are characterized by impairments in social communication associated with repetitive/stereotyped behaviors. Approximately one-third of these patients display gastrointestinal (GI) symptoms, and a growing number of studies suggest abnormalities of gut microbiota in ASD. Gut microbiota and the brain interact through complex pathways. Preliminary evidence in adults with ASD suggests that modulation of the gut microbiota by probiotics and/or prebiotics and more recently by fecal microbiota transplantation could improve GI symptoms but also socio-communication deficit, with persistent improvement at year 2.
