It has been associated with acute exacerbations of chronic obstructive pulmonary disease (COPD); however, it has also been detected in the lower airway in the stable state, but the consequences of RSV in stable disease have not previously been determined. We therefore studied the consequences of RSV persistence in adults with COPD and its effect on airway inflammation and lung function decline.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>A total of 241 sputum samples from 74 patients with COPD (FEV1% predicted, 39.2%; interquartile range, 29.6\u201357.8%) were collected quarterly in the stable state over 2 yr. RSV was detected by polymerase chain reaction (PCR), quantitative microbiology was performed, and inflammatory cytokines were quantified by ELISA.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>RSV RNA was detected in 32.8% of sputum samples. Patients in whom RSV was more frequently detected (&amp;gt; 50% of samples RSV PCR-positive, n = 18) had higher airway inflammation and faster FEV1 decline over the study (101.4 ml\/yr [95% confidence interval, 57.1\u2013145.8]) compared with those with less frequent detection of RSV (n = 56; 51.2 ml\/yr [31.7\u201370.8]; p = 0.01). The observed relationship between RSV detection and accelerated lung function decline was independent of smoking status, exacerbation frequency, and lower airway bacterial load.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Persistent RSV detection in patients with COPD is associated with airway inflammation and accelerated decline in FEV1.
