Autonomic nervous system abnormalities and asthma.
Autonomic nervous system function has been studied both in vitro and in vivo using a variety of methodologies. In asthmatic patients, beta-adrenergic hyporesponsiveness and alpha-adrenergic and cholinergic hyperresponsiveness can be frequently demonstrated. These observations have provided support for the beta blockade theory of asthma, advanced in the late 1960s by Andor Szentivanyi's experiments involving sensitized rodents. However, in addition to asthma, aberrations in autonomic nervous system function have been noted in other individuals including cystic fibrosis patients and their parents, patients with emphysema and bronchitis, and in patients (allergic rhinitis and atopic dermatitis) who have demonstrable IgE antibody responses to a variety of antigens. Thus, although these defects are not specific for asthma, it is noteworthy that these conditions share many clinical features; the ultimate phenotypic expression of these abnormalities may depend on both genetic and environmental factors that have yet to be defined.
