Using integron tests to guide first-line antibiotics for non-severe UTI in adults

Official title: INterest of the Negative Predictive Value of Integrons in the reduCtion of Large Broad-spectrum anTibiotics Consumption for Urinary Tract infectionS: a Randomized Trial

Run by University Hospital, Limoges · NCT07675018 · Data updated 2026-11-12

This trial tests whether detecting integrons in urine can help doctors choose appropriate antibiotics for adults with non-severe urinary tract infections who had a resistant gram-negative infection in the past.

Is this trial a fit for you?

Likely a good fit

Adults (18+) with non-severe UTI requiring hospital or ED care, prior documentation of 3GC-resistant Gram-negative bacteria in the last 6 months, and need for empirical parenteral therapy.

Probably not a fit

Patients without prior 3GC-resistant infections or with integron results not influencing outcomes may see no benefit from the testing strategy.

What this trial studies

This multicenter prospective trial explores whether a molecular test for integrons can guide initial antibiotic therapy for adults with non-severe UTIs. In the experimental arm, positive integron detection leads clinicians to use broad-spectrum options; negative results lead to a narrower, cephalosporin-based approach. The study builds on prior data showing high negative predictive value of integrons for resistance, aiming to reduce unnecessary use of broad-spectrum antimicrobials. Eligible patients are adults with non-severe UTI, fever criteria, documented prior 3GC-resistant bacteria, and requiring parenteral therapy. Outcomes will compare empirical therapy choices and antibiotic exposure between the integron-guided and standard empiric therapy approaches.

Why it matters

Potential benefit: If successful, patients could receive effective first-line antibiotics with less broad-spectrum use, reducing resistance pressure and potential side effects.

How similar studies have gone: Earlier IRIS study showed high negative predictive value of integrons for 3GC resistance, supporting exploration in guiding therapy, though direct impact on empirical treatment in UTIs needs confirmation.
