Clinical study of peanut and nut allergy in 62 consecutive patients: new features and associations. New York, NY, As a consequence of the general increase in allergic sensitization, the prevalence of hypersensitivity reactions to multiple foods that share homologous proteins has become a significant clinical problem. IgE from patients allergic to crustaceans, house dust mite or flies was evaluated for cross-recognition of proteins in house cricket Acheta domesticus (AD), desert locust Schistocerca gregaria (SG) and Yellow mealworm Tenebrio molitor (TM). A knowledge of cross-reactions between different allergens can facilitate the diagnosis of allergy. Anaphylaxis after initial ingestion of rambutan, a tropical fruit. Because of the frequency of severe reactions, there are no comprehensive studies on cross-reactivity to tree nuts. The risk is much lower, about 5%, for allergy to mare's milk (or donkey's milk) which is less cross-reactive with cow's milk. Plant-derived proteins responsible for allergy include various families of pathogenesis-related proteins, protease and α-amylase inhibitors, peroxidases, profilins, seed-storage proteins, thiol proteases, and lectins.
