Background: Pulmonary exacerbations (PEx) in cystic fibrosis (CF) patients decrease lung function, increase symptoms and reduce health-related quality of life (HRQoL). We evaluated associations between 8 symptom-based questions from the Cystic Fibrosis Respiratory Symptom Diary - Chronic Respiratory Infection Symptom Score (CFRSD-CRISS) and the 5-level EuroQOL-5 Dimensions (EQ-5D-5 L) summary score and hypothesized the CFRSD-CRISS would be well-correlated with quality-of-life measures among CF patients with PEx.
Methods: CF patients who had CFRSD-CRISS and EQ-5D-5L measurements on the day of the initial PEx, 7 days later, and at the end of intravenous antibiotic treatment were included.
Background: Chronic Pseudomonas aeruginosa (Pa) airways infection, exuberant local inflammation, and progressive lung function loss are hallmarks of cystic fibrosis (CF). KB001-A is an anti-PcrV PEGylated monoclonal antibody fragment to the Type III secretion system of Pa. This 16-week study evaluated KB001-A associated effect on time-to-need for antibiotics for worsening respiratory signs and symptoms, as well as safety, and treatment-associated changes in symptom scores, inflammatory markers, and spirometry.

Methods: We combined a survey of CF stakeholders with retrospective analyses of a recent observational study of CF PEx to design a multicenter, randomized, prospective study comparing the efficacy and safety of different durations of IV antibiotics for PEx to meet the needs of people with CF and their caregivers.
Background: While the emergence of chronic and mucoid Pseudomonas aeruginosa (Pa) infection are both associated with poorer outcomes among CF patients, their relationship is poorly understood. We examined the longitudinal relationship of incident, chronic and mucoid Pa in a contemporary, young CF cohort in the current era of Pa eradication therapy.
Methods: This retrospective cohort was comprised of patients in the U.
