Seasonal variation in non-specific bronchial reactivity: a study of wheat workers with a history of wheat associated asthma.
To investigate seasonal variation in non-specific bronchial reactivity in wheat workers, we carried out histamine inhalation tests in 29 workers (28 of them men) from a small farming community with symptoms of wheat associated asthma before, during and after the 1983-4 Australian wheat harvest season. Four were cigarette smokers, and the age range was 12-54 (mean (SD) 30 (10)) years. Twenty eig...
متن کاملEffect of inhaled budesonide on bronchial reactivity to histamine, exercise, and eucapnic dry air hyperventilation in patients with asthma.
BACKGROUND It has been suggested that inhaled corticosteroids may provide greater protection against constrictor stimuli that act indirectly such as exercise than those that act directly such as histamine. METHODS The effects of six weeks treatment with inhaled budesonide (800 micrograms twice daily) on bronchial reactivity to histamine, exercise, and eucapnic voluntary hyperventilation of dr...
متن کاملEffect of salbutamol and ipratropium bromide on airway calibre and bronchial reactivity in asthma and chronic bronchitis.
Bronchial reactivity to agonists such as histamine is seen in both chronic bronchitis and asthma, two conditions with different pathological changes in the airways. Salbutamol, when given acutely, reduces bronchial reactivity in patients with asthma, but the mechanism has not been clarified. To determine whether the effect of salbutamol depends on the pathological changes underlying the increas...
متن کاملEstimation and repeatability of the response to inhaled histamine in a community survey.
Epidemiological problems arising from the absence of an agreed definition of asthma have led to the use of bronchial reactivity tests in community surveys of asthma prevalence. Since only a minority of the general population will develop bronchoconstriction in response to the dose of histamine considered acceptable for use in the community it is important to make maximum use of the data availab...
متن کاملPrevalence of asthma, atopy, and bronchial hyperreactivity in bronchiectasis: a controlled study.
The prevalence of atopic diseases and bronchial reactivity to histamine and methacholine was determined in 36 patients with bronchiectasis and in 36 control patients matched for age, sex, and smoking history. There was no difference in the prevalence of asthma, other atopic diseases, family history of atopic diseases, or positive responses to skinprick tests (nine versus five) in the two groups...
