Common ivy (Hedera helix L.) is a ubiquitous plant in Europe whose major allergen falcarinol has moderate allergic potential. It is not related to poison ivy (Toxicodendron spp.). There are no cross reactions between the allergens of common ivy (falcarinol) and poison ivy (urushiol). Contact with common ivy or falcarinol may lead to sensitization and then a delayed hypersensitivity reaction. There are only few cases described in the literature. We report on a male hobby gardener with appropriate clinical history and positive patch test. The pathogenic mechanism is a type IV reaction following a sensitization exposure. Gardeners and landscape architects with frequent exposure to common ivy and thus a high risk of sensitization should wear appropriate protective clothing.
常春藤（洋常春藤）是欧洲一种常见的植物，其主要过敏原法卡林二醇具有中等过敏潜力。它与毒葛（漆树属）无关。常春藤（法卡林二醇）和毒葛（漆酚）的过敏原之间不存在交叉反应。接触常春藤或法卡林二醇可能会导致致敏，进而引发迟发型超敏反应。文献中描述的此类病例很少。我们报告了一名有相关临床病史且斑贴试验呈阳性的男性业余园艺爱好者。致病机制是致敏暴露后的IV型反应。经常接触常春藤因而致敏风险高的园艺工人和景观设计师应穿着适当的防护服。
