Increased peripheral alpha-adrenoceptor response in allergic asthmatics

Allergy. 1988 Jan;43(1):49-52. doi: 10.1111/j.1398-9995.1988.tb02043.x.


The peripheral alpha-adrenoceptor reactivity, measured as dermal blanching response to iontophoretically administered phenylephrine, was studied in 28 allergic asthmatics, 13 patients with allergic rhinoconjunctivitis and 21 healthy controls. The blanching response, which has previously been demonstrated to be mediated via alpha 1-adrenoceptors, was found to be significantly increased in allergic asthmatics compared with controls. It is suggested that there is an increased peripheral alpha-adrenoceptor reactivity in allergic asthma.
