The study found that there is no additional benefit when multiple antipseudomonal classes are used to treat pulmonary exacerbation in people with cystic fibrosis and Pseudomonas aeruginosa infection.
Background: Cystic fibrosis (CF) pulmonary exacerbation (PEx) treatment guidelines suggest that Pseu-domonas aeruginosa ( Pa ) airway infection be treated with two antipseudomonal agents.Methods: We retrospectively studied treatment responses for STOP2 PEx treatment trial (NCT02781610) participants with a history of Pa infection. Mean lung function and symptom changes from intravenous (IV) antimicrobial treatment start to Visit 2 (7 to 10 days later) were compared between those receiv-ing one, two, and three + antipseudomonal classes before Visit 2 by ANCOVA. Odds of PEx retreatment with IV antimicrobials within 30 days and future IV-treated PEx hazard were modeled by logistic and Cox proportional hazards regression, respectively. Sensitivity analyses limited to the most common one-, two-, and three-class regimens, to only IV/oral antipseudomonal treatments, and with more stringent Pa infection definitions were conducted.Results: Among 751 participants, 50 (6.7%) were treated with one antipseudomonal class before Visit 2, while 552 (73.5%) and 149 (19.8%) were treated with two and with three + classes, respectively. Females and participants with a negative Pa culture in the prior month were more likely to be treated with a single class. The most common single, double, and triple class regimens were beta-lactam (BL; n = 42), BL/aminoglycoside (AG; n = 459), and BL/AG/fluoroquinolone (FQ; n = 73). No lung function or symptom response, odds of retreatment, or future PEx hazard differences were observed by number of antipseu-domonal classes administered in primary or sensitivity analyses.Conclusions: We were unable to identify additional benefit when multiple antipseudomonal classes are used to treat PEx in people with CF and Pa .(c) 2022 European Cystic Fibrosis Society.
