We found 12 case reports and four case series, with a total of 37 patients. We reviewed the original articles published on Pubmed, Embase and Cochrane Library before 15 September 2021, on the topic of contact allergy induced by mango and we synthesized the key data. The sensitising substances that have long been suspected are alk(en)yl catechols and/or alk(en)yl resorcinols. The most common clinical manifestation of mango allergy is contact dermatitis, which can be localized or systemic. Our data suggest that peach and mango contain the highest levels of important pan-allergens among the 15 common fruits tested, which agrees with epidemiological data. Papaya, melon, and tomato contained low but detectable levels of the three pan-allergens.Conclusion The allergenic protein levels in these extracts were determined by immuno-dot blotting using rabbit anti-rSola l 1, 3, and 4 polyclonal antibodies.ResultsAmong all 15 fruit extracts tested, peach and mango contained the highest levels of profilin, nsLTP, and PR-10. Extracts of the most popular fruits, including apple, banana, carrot, celery, dragon fruit, hami melon, jujube, kiwi, mango, melon, orange, papaya, peach, persimmon, and tomato, in Taiwan were prepared in PBS. This study aimed to determine LTP, profilin, and PR-10 in the 15 most popular fruits in Taiwan.MethodscDNA encoding profilin (Sola l 1), nonspecific lipid transfer protein (nsLTP, Sola l 3), and pathogenesis-related protein (PR-10, Sola l 4) were cloned into the pQE30, expressed in Escherichia coli, and purified. Identification of allergenic protein levels in food allows for more precise dietary advice. Many plant food allergens have been implicated in cross-reactivities and may cause repetitive pan-allergenic exposures, which increase the severity of patients’ allergic symptoms.
