Data were prospectively collected, and, in a subgroup of patients, COPD Assessment Test scores and human rhinovirus identification by polymerase chain reaction were available. Patients were also defined as having infrequent or frequent exacerbations (&amp;lt;2 or \u22652 exacerbations\/yr, respectively).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Measurements and Main Results<\/jats:title>\n                    <jats:p>At an aggregate of 4,368 visits, 209 patients with COPD were asked about their nasal symptoms. At 2,033 visits when the patients were stable, the odds ratio (OR) for nasal discharge increased by 1.32% per year (95% confidence interval [CI], 1.19\u20131.45; P\u2009&amp;lt;\u20090.001); the OR for sneezing increased by 1.16% (95% CI, 1.05\u20131.29; P\u2009=\u20090.005); the OR for postnasal drip increased by 1.18% (95% CI, 1.03\u20131.36; P\u2009=\u20090.016); and the OR for anosmia increased by 1.19% (95% CI, 1.03\u20131.37; P\u2009=\u20090.015). At visits when the patients were having exacerbations, nasal discharge was present for 7 days and blocked nose, sneezing, and postnasal drip increased for just 3 days. Anosmia did not change. Nasal discharge was more likely in patients with frequent exacerbations (OR, 1.96; 95% CI, 1.17\u20133.28; P\u2009=\u20090.011), and COPD Assessment Test scores were higher by 1.06 units (95% CI, 0.32\u20131.80; P\u2009=\u20090.005) when patients were stable and higher by 1.30 units (95% CI, 0.05\u20132.57; P\u2009=\u20090.042) during exacerbations.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Upper airway symptoms increase over time in patients with COPD and are related to the frequent exacerbation phenotype.
