Over the last decades, the incidence of allergic rhinitis (AR) has revealed a constantly increasing tendency worldwide. In Japan, Japanese cedar pollinosis (JCP) and perennial allergic rhinitis (PAR) mostly due to mite allergens are the predominant types of seasonal and nonseasonal ARs, respectively. We previously reported a relationship between low levels of secretory immunoglobulin A (sIgA) in saliva and clinical AR manifestations in adult patients with JCP. To confirm and extend our previous study, we conducted a cross-sectional study, in which salivary sIgA levels in adolescent and adult patients with symptomatic JCP and PAR were compared with levels in age- and gender-matched non-allergic control individuals during the Japanese cedar pollen dispersing season. The results showing the significantly lower salivary sIgA levels in JCP and PAR patients compared to control individuals led us to the conclusion that there is a negative correlation between salivary sIgA levels and clinical occurrence of AR in adolescents and adults. Moreover, it was also found that age and gender have no significant effect on salivary sIgA levels.
