Background: Pseudomonas aeruginosa ( Pa) is the predominant pulmonary pathogen in patients with cystic fibrosis (CF). Tobramycin nebulization is used for the eradication of Pa infection. Nowadays, tobramycin dry powder inhalation (DPI) is available as well. This study reports the results of eradicating Pa with tobramycin DPI versus nebulization. Methods: Adult CF patients with a Pa isolation between September 2010 and September 2017 from the University Medical Centre Groningen (UMCG), the Netherlands, were included in this retrospective study. Results: In total 27 Pa isolations were recorded. In 13 of these, eradication was attempted with tobramycin, 7 with DPI and 6 with nebulization. DPI eradicated Pa successfully in six isolations (85.7%). Of these, one patient received additional oral ciprofloxacin and one received intravenous ceftazidime. Nebulization eradicated three Pa isolations (50.0%), in two of these, additional oral ciprofloxacin was given. Conclusion: Eradication rates of DPI tobramycin are comparable with those for nebulized tobramycin reported in the literature. This study suggests that DPI tobramycin is an alternative to nebulized tobramycin for eradication of Pa. Trial registration: The Medical Ethics Committee of the UMCG granted a waiver (METC2017-349), as they concluded that this study was not subject to the Medical Research Involving Human Subjects Act.

Abstract Background Multidrug-resistant (MDR) Pseudomonas aeruginosa is a challenging pathogen to treat. Ceftolozane/tazobactam (C/T) is a combination cephalosporin and β-lactamase inhibitor that has demonstrated activity against MDR P. aeruginosa, including carbapenem-resistant isolates. The objective of this study was to evaluate multidrug resistance in P. aeruginosa isolates obtained from patients treated with C/T across the Veterans Affairs (VA) Healthcare System nationally. Methods Hospitalized patients who received at least 1 dose of CT between January 2015 and April 2018 and had a positive P. aeruginosa culture were included in this retrospective study. Culture source and antimicrobial susceptibility reports were assessed for each P. aeruginosa isolate. Isolates were categorized as multidrug-resistant based on the Centers for Disease Control (CDC) definition. Resistance rates were categorized by source of culture. Results We identified 174 positive P. aeruginosa cultures among 154 patients who received at least one dose of C/T during the study period. The most common sources of isolates were lung (40% of patients), urine (21%), skin and soft tissue (15%), blood (14%), and bone/joint (14%). Most patients (98.1%) had isolates that were MDR, with high rates of carbapenem (84.4%), extended-spectrum cephalosporin (82.5%), and fluoroquinolone (79.9%) resistance. In this cohort, 50.6% of patients received at least one antibiotic prior to initiating C/T to which their clinical culture was not susceptible. Conclusion Antibiotic resistance was high in this cohort of patients with P. aeruginosa, and as a result, use of non-susceptible antibiotics occurred in 50.6% of patients before C/T was started. The high carbapenem resistance rates are of great clinical concern, but highlight an area of utilization for C/T given its activity against carbapenem-resistant P. aeruginosa.

Resistance Patterns

Since 2014, several global and national guidelines have been introduced to address the problem of antimicrobial resistance. We conducted a campaign in a tertiary hospital to promote appropriate quinolone use through educational lectures in 2018. The aim of this retrospective study was to evaluate the changes in the following: prescription characteristics, trend of oral quinolone use, and antibiotic susceptibility of bacteria from 2013 to 2020. Antimicrobial use was assessed as days of therapy per 1000 patient-days. We found a significant reduction in unnecessary antibiotic prescriptions between December 2013 and December 2020. Significant negative trends were detected in the use of quinolones over 8 years (outpatients, coefficient = −0.15655, p < 0.001; inpatients, coefficient = −0.004825, p = 0.0016). In particular, the monthly mean use of quinolones among outpatients significantly decreased by 11% from 2013 to 2014 (p < 0.05) and reduced further by 31% from 2017 to 2020 (p < 0.001). A significant positive trend was observed in the susceptibility of Pseudomonas aeruginosa to levofloxacin (p < 0.001). These results demonstrate that the use of oral quinolones was further reduced following educational intervention and the bacterial susceptibility improved with optimal quinolone usage compared to that in 2013.
