PG - 395-8 AB - The effect of kissing on allergen-induced skin wheal responses and plasma neurotrophin levels were studied in 30 normal subjects, 30 patients with allergic rhinitis (AR), and 30 patients with atopic dermatitis (AD). All of the patients with AR or AD are allergic to house dust mite (HDM) and Japanese cedar pollen (JCP). They are all Japanese and they do not kiss habitually. The subject kissed freely during 30 min with their lover or spouse alone in a room with closed doors while listening to soft music. Before and after kissing, skin prick tests were performed using commercial HDM allergen, JCP allergen, as well as histamine and control solution, and wheal responses were measured. Simultaneously, plasma levels of neurotrophin, including nerve growth factor (NGF), brain-derived neurotrophic factor (BDNF), neurotrophin-3 (NT-3) and -4 (NT-4) were measured. Kissing significantly reduced wheal responses induced by HDM and JCP, but not by histamine, and decreased plasma levels of NGF, BDNF, NT-3, and NT-4 in patients with AR or AD, while it failed to do so in normal subjects. These finding indicate that kissing have some implication in the study of neuroimmunology in allergic patients.
