What this trial studies

This study investigates the impact of the probiotic ASTARTE™, which contains specific strains of Lactobacillus, on the microbiome composition in women aged 18-40 years who experience recurrent urinary tract infections (rUTIs). Over a 6-month period, participants will receive either the probiotic or a placebo in a randomized, double-blind, placebo-controlled design. The primary outcome will be the incidence of symptomatic UTIs, aiming to determine if the probiotic can effectively reduce the risk factors associated with rUTIs. The study seeks to provide insights into the potential benefits of dietary supplements in managing recurrent infections.

Why it matters

Potential benefit: If successful, this study could provide a non-antibiotic approach to reducing the incidence of recurrent urinary tract infections in women.

How similar studies have gone: Previous studies have suggested that probiotics can effectively reduce the risk of infections, indicating potential success for this approach.
