Acerola and Latex Allergy
Raulf-Heimsoth et al present the case of a 37 year old man who developed anaphylaxis after drinking a glass of apple juice that has been supplemented with acerola (often added to increase vitamin C content of products such as juices).
Testing showed that the man experienced no reactions to apple juice. Further testing identifies acerola as the problem and the allergen for latex-acerola cross-reactivity was identified as 'Hev b 6.01'. They recommend that allergists include acerola on the list of latex-cross-reactive food allergens.
Anaphylactic reaction to apple juice containing acerola:
Cross-reactivity to latex due to prohevein.
