    AbstractThe aim of this study was to investigate whether inhaled corticosteroid (ICS) use affects outcome in patients with chronic obstructive pulmonary disease (COPD) admitted with community-acquired pneumonia (CAP). This was a prospective, observational study of patients with spirometry-confirmed COPD presenting with a primary diagnosis of CAP in Lothian, UK. Outcome measures were compared between ICS users and non-ICS users. Of 490 patients included in the study, 76.7% were classified as ICS users. ICS users had higher Global Initiative for Chronic Obstructive Lung Disease (GOLD) stage compared with non-ICS users (mean ± sd 3.2 ± 0.8 versus 2.6 ± 0.9; p<0.0001). There were no significant differences in pneumonia severity (mean ± sd Pneumonia Severity Index (PSI) 4.2 ± 0.8 versus 4.3 ± 0.8 (p = 0.3); mean ± sd CURB-65 score 2.1 ± 1.3 versus 2.3 ± 1.3 (p = 0.07)) or markers of systemic inflammation (median C-reactive protein 148 (interquartile range 58-268) mg·L(-1) versus 183 (IQR 85-302) mg·L(-1); p = 0.08) between ICS users and non-ICS users. On multivariable analysis, after adjustment for COPD severity and PSI, ICS use was not independently associated with 30-day mortality (OR 1.71, 95% CI 0.75-3.90; p = 0.2), 6-month mortality (OR 1.62, 95% CI 0.82-3.16; p = 0.2), requirement for mechanical ventilation and/or inotropic support (OR 0.73, 95% CI 0.33-1.62; p = 0.4) or development of complicated pneumonia (OR 0.71, 95% CI 0.25-1.99; p = 0.5). Prior ICS use had no impact on outcome in patients with COPD admitted with CAP.
