Antimicrobial Therapy for Infections Due to Pseudomonas Aeruginosa With Difficult-to-treat Resistance: a Real-world, Prospective, Multicenter Cohort Study

What this Trial Is About

Researchers are evaluating different antimicrobial therapies for infections caused by difficult-to-treat Pseudomonas aeruginosa, a type of bacteria resistant to many common antibiotics. This study focuses on comparing new beta-lactam/beta-lactamase inhibitor combinations, cefiderocol, and older treatments like aminoglycosides and colistin to understand their effectiveness in real-life settings for patients facing these challenging infections. The study is a prospective, multicenter cohort involving patients who require intravenous antibiotic treatment for their P. aeruginosa infections. Participating patients will receive one of the available antimicrobial options, and their bacterial samples will be analyzed centrally to assess susceptibility and resistance mechanisms. The study collects clinical data throughout treatment and monitors outcomes such as cure rates, resistance development, adverse events, and mortality. Participants will be followed until hospital discharge and up to 28 days after treatment completion. Researchers will track clinical cures, microbiological eradication, adverse events, emergence of resistance, and acquisition of other multidrug-resistant bacteria. Data collection includes electronic case reports and laboratory testing on bacterial isolates. The total participation duration varies according to hospital stay and follow-up schedules, with rigorous monitoring of safety and treatment outcomes.
