BACKGROUND Cough in the patients with cough variant asthma is triggered by bronchoconstriction, which responds to bronchodilator therapy. Following airway narrowing induced by inhaled methacholine, deep inspiration (DI) causes dilation of the airways in both asthmatic and non-asthmatic subjects. The aim of the present study was to investigate the relationship between bronchodilator effect of DI...
I read with interest the valuable article by Pratter et al (November 1999),1 regarding the role of sinus imaging in the management of chronic cough. Figure 2 in this article contains a useful algorithm for investigation and treatment of chronic cough. Unfortunately, one potentially important cause of cough will be missed by following this algorithm. Eosinophilic bronchitis is a recently describ...
Enhanced cough response has been frequently observed in chronic cough. Recently, extrathoracic airway constriction to inhaled histamine was demonstrated in some chronic cough patients. However, relation between extrathoracic airway hyperresponsiveness (EAHR) and cough sensitivity determined by capsaicin inhalation is unclear in each etiological entity of chronic cough. Seventy-seven patients, w...
BACKGROUND Substance P (SP) is involved in the pathogenesis of cough in animal models. However, few studies in humans have been reported and the roles of SP in clinical cough remain obscure. OBJECTIVES To clarify the relevance of plasma levels of SP in patients with persistent cough. METHODS We studied 82 patients with cough persisting for at least 3 weeks and 15 healthy controls. Patients ...
BACKGROUND Cough is one of the most common reasons for visiting a clinic. The causes of cough differ according to the duration of cough. Infectious disease is commonly observed in acute cough while noninfectious disease is commonly observed in chronic cough. On the other hand, cough is frequently observed in patients with asthma/cough variant asthma (CVA). OBJECTIVE In this study, we investig...
