Methods of testing nonspecific bronchial hyperresponsiveness.
Many methods of testing nonspecific bronchial responsiveness have been devised, since Curry first demonstrated the heightened bronchial responsiveness of asthmatics to histamine. The preferred rou1e of administration of bronchoconstrictors at the presem Lime is by inhalation, rather than systemically, in order to minimize unacceptable side effects. The agents inhaled have included irritants, ch...
متن کاملLevomepromazine (Nozinan) reduces nonspecific bronchial hyperreactivity in asthmatics.
Ten patients with bronchial asthma were challenged with histamine before and after receiving saline and active drug (levomepromazine or antazoline) (a total of six challenges). The antihistaminic effect of levomepromazine (25 mg) was found to be comparable to that of antazoline (100 mg), evaluated from skin prick tests. Prechallenge forced expiratory volume in one second (FEV1) was found to be ...
متن کاملPredictive value of nonspecific bronchial responsiveness in occupational asthma.
BACKGROUND The diagnosis of occupational asthma (OA) can be challenging and needs a stepwise approach. However, the predictive value of the methacholine challenge has never been addressed specifically in this context. OBJECTIVE We sought to evaluate the sensitivity, specificity, and positive and negative predictive values of the methacholine challenge in OA. METHODS A Canadian database was ...
متن کاملDistribution of bronchial nonspecific reactivity in the general population.
We investigated 654 subjects of a small Lombardy (Italy) town between 15 and 64 years of age who were representative of the general population. By clinical examination, the sample included 535 normal subjects (164 normal smokers, 341 normal nonsmokers, 30 normal subjects with acute upper respiratory illness within 30 days before the challenge), 50 with chronic bronchitis, 26 with asthma, and 43...
