Yu L, Wei W, Wang L, Huang Y, Shi C, Lü H, Qiu Z. Upper-airway cough syndrome with latent eosinophilic bronchitis. Lung 2009; 188:71-6. [PMID: 19862573 DOI: 10.1007/s00408-009-9192-0] [Citation(s) in RCA: 16] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/15/2009] [Accepted: 09/29/2009] [Indexed: 12/15/2022]
Abstract
Upper-airway cough syndrome often coexists with other diseases that elicit chronic cough. However, the concomitant conditions are not always relevant to chronic cough, which complicates the cause diagnosis of chronic cough. The objective of this study was to explore the diagnosis and clinical implication of upper-airway cough syndrome with latent eosinophilic bronchitis. Eleven patients with upper-airway cough syndrome and latent eosinophilic bronchitis were retrospectively analyzed for their clinical manifestations, changes of eosinophilia in induced sputum, and cough threshold with capsaicin defined as capsaicin concentration that elicits two or more coughs (C2) and five or more coughs (C5) between pretreatment and post-treatment. All patients reported a history of allergic rhinitis, showed persistent dry cough or small amounts of viscid sputum with a time course of 2-60 months (median = 7 months), and presented with symptoms and signs of rhinitis, normal lung function, and airway responsiveness. Initial eosinophil percentage in induced sputum was 3.5-8.0%. Cough disappeared after 2-5 (3 +/- 1) weeks of only oral antihistamine. With successful treatment, cough threshold C2 increased from 1.73 +/- 1.45 to 4.43 +/- 4.50 micromol/L (t = 2.64, P = 0.025) and C5 increased from 2.79 +/- 2.16 to 10.10 +/- 8.22 micromol/L (t = 3.10, P = 0.011). However, there was no significant change of eosinophil percentage in induced sputum (4.8 +/- 1.5% vs. 4.4 +/- 1.4%, t = 0.84, P = 0.427). Upper-airway cough syndrome with latent eosinophilic bronchitis is a unique condition. The recognition of the entity may avoid unnecessary use of corticosteroids.

Abstract
Cough is a major cause of disability and distress worldwide. In June 2007, the First American Cough Conference was held in New York City and covered a spectrum of topics of interest to the basic scientist as well as the clinician. The conference was organized by Dr. Peter Dicpinigaitis and its proceedings are published in the February Supplement of LUNG. This supplement consists of a series of articles that provide a valuable overview of recent advances in our understanding of mechanism, etiology, and treatment of cough and constitute an adjunct to the guidelines recently published by the American College of Chest Physicians, the British Thorax Society, the European Respiratory Society, and the Japanese Respiratory Society.
