Prevalence and characterization of chronic rhinosinusitis in patients with non–cystic fibrosis bronc

In this retrospective cohort study, researchers identified the prevalence of chronic rhinosinusitis (CRS) among bronchiectasis patients affiliated with a US tertiary medical center. In addition, they determined which comorbid diseases were correlated with the presence of CRS in bronchiectasis patients. In 45% of patients with bronchiectasis, CRS was present. Majority of bronchiectasis patients, both with and without CRS, were women. Findings suggested an association of asthma, allergic rhinitis, gastroesophageal reflux disease, and antibody deficiency with the presence of CRS in bronchiectasis patients after controlling for demographic factors. Such results have medical implications for the diagnosis and future research of patients with bronchiectasis.
