  1. Allergic responses to pollen of ornamental plants : High incidence in the general atopic population and especially among flower growers.

    Article - En anglais

    Background 

    The incidence of allergy to pollen of ornamental plants has not been deeply investigated, and its extent has remained obscure.

    Most of such studies have concentrated only on pollen of ornamental plants from the Asteraceae family (Compositae).

    In this study an attempt was made to clarify whether various other ornamental plants may also cause skin responses and allergic symptoms among allergic urban dwellers and among rural flower growers.

    Methods 

    Two hundred ninety-two patients were referred for allergic evaluation by their primary physicians ; 75 flower growers and 44 university students were evaluated.

    For all participants, a detailed health record was obtained, and skin prick tests (SPTs) were performed.

    Extracts for SPTs included commercial common airborne allergens and autochthonous pollen extracts of It species of plants belonging to the Asteraceae, Ranunculaceae, Liliaceae, Scrophulariaceae, and Genetianaceae families.

    Results 

    Fifty-one of the 292 patients (17%) referred for allergic evaluation had positive SPT responses to pollen of various ornamental plants.

    A similar incidence was found among the students (23%). However, the incidence among flower growers was significantly higher, reaching 52%. Higher incidence (83%) of positive SPT responses to ornamental plants was found among flower growers also sensitive to the common allergens. (...)
