Plants and plant products play a vital role in our daily life. Because of their naturalness, plant-based goods are becoming increasingly popular in modern world. However, plant-based products can induce allergic contact dermatitis, the most common clinical manifestation of contact allergy. Skin patch testing should be done since allergic contact dermatitis is characterized by unspecific skin rashes. The goal of this research is to conduct a literature review on contact allergy to plants or plant materials, assess contact allergy frequency changes from 2015 to 2020 and determine demographic and clinical characteristics of the individuals. This study included 2007 patients, 1970 of them were examined with European baseline and 37 with plant series allergens. The incidence of at least one positive reaction to the baseline series was 55,22% (CI 53,02-57,42%). Plant induced allergic contact dermatitis prevalence increased from 9,13%, CI 5,22-13,04% in 2015, peaked in 2018 (14,21%, CI 10,6-17,82%), and then declined to 13,57%, CI 9,56-17,58% in 2020, but findings were statistically insignificant (p=0,5706). Sensitization to balsam of Peru was found in 7,05% of patients examined for suspected allergic contact dermatitis and was the most prevalent plant allergen in European baseline series. Sensitization to colophony was 4,56%, and sensitization to sesquiterpene lactone mix – 0,81%. Woman (p=0,001416) and atopic patients with allergy histories (p=0,000352) are more likely to develop contact allergy to plants. The incidence of contact allergy decreaced statistically significantly in the elderly groups (p=0,0001). Allergic contact dermatitis was mostly causing face skin rashes (p=0,012773). Because there is no specific etiological treatment, the main aim of controlling contact dermatitis is to identify allergens using skin patch testing and prevent them. |
