For confirmation of asthma diagnosis, bronchial provocation
tests can be included in asthma prevalence protocols as the bronchial reversibility test might show false negative results particularly in subjects with intermittent symptoms.
and dilation test were not included in the protocol.
The results of this study indicate a higher frequency of bronchial hyperresponsiveness to bronchial provocation
by the exercise method (40%) than that by the hypertonic saline solution inhalation method (26.
Partial responder and nonresponder patients entered the next diagnostic phase: a methacholine bronchial provocation test (MPT) (7) and eosinophil count with induced sputum by hypertonic saline (3% NaCl).
If treatment succeeded at any step in our algorithm, we asked patients to stop taking medication--with the exception of those who had positive results on methacholine bronchial provocation test.
Elsewhere, oral or bronchial provocation
with different doses of aspirin is common.
Subsequently, all subjects were given a standard bronchial provocation
test, during which they inhaled five breaths of increasing concentrations of allergens.
Nasal provocation can be eschewed in favor of bronchial provocation
, but the upper airway test has several distinct advantages.
Subjects were randomised to receive either inhaled Pumactant or a placebo before receiving a standard bronchial provocation
test, inhaling five breaths of increasing concentrations of allergens.
