Title Dermatitis from common ivy (Hedera helix L. subsp. helix) in Europe: past, present and future
Bibliographic information Apr. 2010, Vol.62, No.4, p.201-209. Illus. 38 ref.
Abstract Common ivy (Hedera helix subsp. helix) is a well-known native and ornamental plant in Europe. Contact dermatitis from ivy has been regularly reported since 1899. Recently, it has been suggested that allergic contact dermatitis from the plant may be under-diagnosed, partly due to lack of commercial patch test allergens. This article presents the results of patch testing with the main common ivy allergen, falcarinol, during a 16-year period and reviews the newer literature. Cases published since 1987 were retrieved from the PubMed database. One hundred and twenty-seven Danish patients were tested with falcarinol and 10 (7.9%) tested positive. Seven were occupationally sensitized. Between 1994 and 2009, 28 new cases of contact dermatitis from ivy were reported, two of which were occupational. Only 11 of the 28 patients were tested with pure allergens. Falcarinol is not only widely distributed in the ivy family, but also in the closely related Apiaceae. Sensitization may occur in childhood or in adults pruning ivy plants or handling them in an occupational setting. In view of the ubiquity of falcarinol-containing plants and the relatively high prevalence of positive reactions in aimed patch testing, falcarinol should be considered as a priority plant allergen for commercial availability and inclusion in the plant series worldwide.
