Does beclomethasone dipropionate attenuate airways hyperresponsiveness to neurokinin A and histamine in asthma?
Airway responsiveness to histamine and NKA is reduced by BDP to the same extent. As a result of these findings, provocation with NKA is unlikely to provide additional useful information in the assessment of airway inflammation in asthma.
G4 patients in Belgium have the same SVR as G1 patients. It is lower than the SVR described in Arab countries, especially for Black G4 patients.
