Exhaled nitric oxide levels in patients with atopic cough and cough variant asthma.
BACKGROUND AND OBJECTIVE Atopic cough (AC) is an established clinical entity in Japan, in which patients present with a chronic persistent non-productive cough. Exhaled nitric oxide (NO) is a biomarker of eosinophilic airway inflammation. The present study examined whether exhaled NO levels were increased in AC in comparison with cough variant asthma (CVA) and bronchial asthma (BA). METHODS C...
متن کاملCough variant asthma and atopic cough
Chronic cough has been reported to be the fifth most common complaint seen by primary care physicians in the world, the third in Italy. Chronic cough in non-smoking, non-treated with ACE-inhibitor adults with normal chest radiogram could be a symptom of asthma and can be sub-classified into: cough-variant asthma, atopic cough, and eosinophilic bronchitis. This review discusses the differential ...
متن کاملComparison of atopic cough with cough variant asthma: is atopic cough a precursor of asthma?
BACKGROUND We have described a group of patients who present with isolated chronic bronchodilator resistant non-productive cough with an atopic constitution, eosinophilic tracheobronchitis, and airway cough receptor hypersensitivity without bronchial hyperresponsiveness, which we have termed "atopic cough". Although cough variant asthma (in which the cough responds to bronchodilators) is recogn...
متن کاملCough and Exhaled Nitric Oxide Levels: What Happens with Exercise?
Cough associated with exertion is often used as a surrogate marker of asthma. However, to date there are no studies that have objectively measured cough in association with exercise in children. Our primary aim was to examine whether children with a pre-existing cough have an increase in cough frequency during and post-exercise. We hypothesized that children with any coughing illness will have ...
متن کاملValidity of Spirometry for Diagnosis of Cough Variant Asthma
Background Cough variant asthma (CVA) is a chronic or recurrent cough without wheezing accompanied by bronchial hyper-responsiveness and eosinophilic inflammation of the airways. This study aimed to evaluate the validity of spirometry in the diagnosis of CVA, as well as determining the specificity and sensitivity of spirometry parameters in CVA. Materials and Methods This descriptive observat...
