Using fecal microbiota transplantation to prevent recurrent urinary tract infections

Faecal Microbiota Transplantation as Means of Preventing Recurrent Urinary Tract Infections

Phase2; Phase3 Interventional Helsinki University Central Hospital · NCT06050148

This study is testing if a treatment using gut bacteria from healthy donors can help women who often get urinary tract infections to have fewer of them.

What this trial studies

This study investigates the use of fecal microbiota transplantation (FMT) as a method to prevent recurrent urinary tract infections (UTIs) in female patients. Participants will receive either FMT or a placebo to assess the effectiveness of this intervention against UTIs caused by both sensitive and ESBL-producing E. coli. The study aims to determine if altering gut microbiota can reduce the frequency of UTIs in individuals with a history of recurrent infections. Eligible participants must have experienced multiple UTIs within a specified timeframe and provide informed consent to participate.

Who should consider this trial

Good fit: Ideal candidates for this study are women aged 18 and older with a history of recurrent urinary tract infections.

Not a fit: Patients with gastrointestinal diseases, pregnancy, or those on immunosuppressive therapy may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly reduce the incidence of recurrent urinary tract infections in women, improving their quality of life.

How similar studies have performed: Other studies have shown promise in using fecal microbiota transplantation for various conditions, but this specific application for recurrent UTIs is relatively novel.
