Study Comparing Two Antibiotic Treatments for Early Pseudomonas Aeruginosa Infection in Adults With Bronchiectasis

What this Trial Is About

Researchers are studying adults with bronchiectasis who have a recent infection of Pseudomonas aeruginosa PA in their airways. This infection is linked to more frequent worsening of symptoms, lower quality of life, and a higher risk of death. The study compares two antibiotic treatment plans to find out if a simpler oral and inhaled antibiotic combination works as well as a more intensive treatment involving intravenous antibiotics. This research aims to provide clearer evidence to guide how these infections should be treated for better health and economic outcomes. The study tests two treatment approaches over a 3-month period. One group receives an oral fluoroquinolone antibiotic combined with inhaled colistimethate sodium, starting with 14 days of both followed by 2.5 months of inhaled antibiotic alone. The other group gets intravenous beta-lactam antibiotic plus the same oral and inhaled antibiotics in the initial 14 days, then continues inhaled treatment alone for 2.5 months. After treatment, participants are followed for 9 more months to monitor their health and infection status, totaling 12 months from the start of therapy. Participants will have regular check-ups during and after treatment to measure how well PA is eradicated and to track any return of infection or worsening symptoms. Questionnaires will assess quality of life and treatment burden at the start, 3 months, and 12 months. Researchers will also monitor antibiotic resistance, adverse events, and healthcare costs over one year. This comprehensive follow-up helps evaluate both the medical and economic impact of the two antibiotic regimens in managing early PA airway infection in bronchiectasis.
