Collecting E. Coli Samples from Patients with Recurrent Urinary Tract Infections

Systematic Analysis of Bacterial Multidrug Tolerance in Longitudinal Isolates of Patients That Are Prone to Developing Urinary Tract Infections

Observational Université Catholique de Louvain · NCT05826067

This study is collecting samples of E. coli from patients with recurring urinary tract infections to see how these bacteria behave and why they might keep coming back.

What this trial studies

This observational study aims to collect clinical isolates of Escherichia coli from patients experiencing recurrent urinary tract infections. Samples will be gathered during routine medical procedures from patients with various conditions, including those with suprapubic or nephrostomy catheters. The study seeks to understand the persistence of E. coli strains in natural settings, which may contribute to chronic infections and antibiotic resistance. Detailed medical histories will be compiled to assess the impact of previous antibiotic treatments on infection recurrence.

Who should consider this trial

Good fit: Ideal candidates include hospitalized or ambulatory patients diagnosed with urinary tract infections caused by E. coli, particularly those with neurological disorders or requiring catheterization.

Not a fit: Patients who refuse treatment, are non-compliant with therapy, pregnant, or do not consent to participate may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved understanding and treatment strategies for recurrent urinary tract infections caused by E. coli.

How similar studies have performed: While studies on E. coli and urinary tract infections exist, this specific approach focusing on natural strains and persistence is relatively novel.
