BACKGROUND: To evaluate the relationship between lung parenchymal abnormalities on chest CT and health-related quality of life in adult cystic fibrosis (CF). METHODS: The chest CT scans of 101 consecutive CF adults (mean age 27.8±7.9, 64 males) were prospectively scored by two blinded radiologists in consensus using a modified Bhalla score. Health-related quality of life was assessed using the revised Quittner Cystic Fibrosis Questionnaire (CFQ-R). Multiple regressions were performed with each of the CFQ-R domains and all clinical and imaging findings to assess independent correlations. RESULTS: There were 18 inpatients and 83 outpatients. For the cohort of inpatients, CT abnormalities were significantly (P<0.005 for all) associated with Respiratory Symptoms (Air Trapping), and also with Social Functioning (Consolidation) and Role Functioning (Consolidation). For outpatients, CT abnormalities were significantly (P<0.005 for all) associated with Respiratory Symptoms (Consolidation) and also with Physical Functioning (Consolidation), Vitality (Consolidation, Severity of Bronchiectasis), Eating Problems (airway wall thickening), Treatment Burden (Total CT Score), Body Image (Severity of Bronchiectasis) and Role Functioning (Tree-in-bud nodules). Consolidation was the commonest independent CT predictor for both inpatients (predictor for 2 domains) and outpatients (predictor in 3 domains). Several chest CT abnormalities excluded traditional measures such as FEV1 and BMI from the majority of CFQ-R domains. CONCLUSIONS: Chest CT abnormalities are significantly associated with quality of life measures in adult CF, independent of clinical or spirometric measurements.
