Strategy using bacterial DNA detection to guide antibiotics in immunocompromised patients with ventilator-associated or hospital-acquired pneumonia
Official title: Impact of a Strategy Based on the PCR Testing System on Appropriate and Targeted Antimicrobial Treatment in Immunocompromised Patients With Suspected Ventilator-associated Pneumonia or Hospital-acquired Pneumonia Requiring Mechanical Ventilation : a Randomized Controlled Unblinded Trial
Run by University Hospital, Lille · NCT05405491 · Data updated 2026-11-12
This study tests whether using a PCR-based method to tailor antibiotics in immunocompromised ICU patients with suspected VAP or HAP on mechanical ventilation can improve the use of targeted antibiotics within 24 hours of diagnosis.

Is this trial a fit for you?
✓Likely a good fit
Adult ICU patients who are immunocompromised, on mechanical ventilation, and have suspected VAP or HAP.
✕Probably not a fit
Patients without immunodeficiency or those not on mechanical ventilation, or whose pneumonia is not suspected to be VAP/HAP, may not benefit.

What this trial studies
RESPIRE is a randomized, unblinded study in ICU patients who are immunocompromised and require mechanical ventilation for suspected ventilator-associated or hospital-acquired pneumonia. It compares a PCR-based strategy to standard culture-based care to see if earlier, more precise antibiotic targeting can be achieved. The primary goal is to increase the proportion of patients receiving targeted antimicrobial therapy within 24 hours after diagnosis. Outcomes will consider antibiotic appropriateness and timing, with implications for antimicrobial stewardship in vulnerable populations.
Why it matters
Potential benefit: If successful, patients may receive more appropriate antibiotics sooner, potentially reducing exposure to broad-spectrum therapy and improving outcomes.
How similar studies have gone: Prior approaches using rapid molecular testing for pneumonia management have shown promise, but this exact PCR-based strategy in immunocompromised, ventilated patients is novel or not yet widely established.
