Product Information

Poltronieri et al. (2002) [ 725] used Sera from 5 SPT and challenge positive patients and from 1 other with a high RAST who was not tested further. The N-terminal sequence of the 2S albumin is VTXEEGXYSISDQSKVGE (Poltronieri et al. 2002 [ 725]). An internal sequence QXIRSPDREM was also reported. Note that the Swissprot entry makes these into one sequence. Poltronieri et al. (2002) [ 725] used 10-12% acrylamide (or 16% to resolve low molecular mass proteins) 1D gels for separation. Bargman et al. (1992) [734] used 10% acrylamide 1D gels for separation. Samples were reduced with beta-mercaptoethanol and heated for 5 minutes at 100 degrees C.

Bargman et al. (1992) [734] report found that 7/8 patients showed diverse IgE specificity and one (RAST ratio 2.1) did not bind the extract. Binding to a 45-50 kDa protein or group of proteins was frequent and binding to 70 kDa fell after blanching.

Effects of roasting, blanching, autoclaving, and microwave heating on antigenicity of almond (Prunus dulcis L.) proteins. Almond may be present as a “hidden allergen” in commercial food preparations; a case of almond-induced anaphylaxis due to the ingestion of curry is described. Due to possible cross-reactivity, almond-allergic patients should avoid other tree nuts, such as hazelnut and Brazil nuts, unless their good tolerance has been clearly proven by reliable tests. Poltronieri et al. (2002) [ 725] shows the Mr of the 2S albumin as 12 kDa but Sathe et al. (2001) [ 730] report approximately 16 kDa. Many studies report allergy to "tree nuts". Allergy to almond was the third most common of the tree nuts reported by Sicherer et al. (2001) [ 826] with 15% of the 1667 self-reported nut allergic registrants reporting almond allergy. In a later self-reported survey, Sicherer et al. (2003) [ 736] report that almond is the third most common tree nut to cause allergy in the USA after walnut and cashew with 32/82 responders reporting allergy. Social media is awash with posts urging parents of children with nut allergies not to use the Nivea Sun Kids protect and care skin protection, which has 'almond oil' listed as one of the ingredients.

Reactions to nuts and seeds can also occur as a consequence of hidden nut ingredients or traces of nuts and certain seeds introduced as a consequence of food handling or manufacturing. As a result tree nuts and seeds have been included in Annex IIIa of the EU food labelling directive. The following (including products thereof) must be declared on a label if they have been deliberately included in a food:Nature of main cross-reacting proteins: The almond 45 kDa allergen is a 7S cupin and the N-terminal sequence is closest to that of lupin.

Process, chemical, enzymatic: Not known but the disulphide linked alpha-helical structures of this protein family is likely to be very stable. Almond, hazelnut, Walnut, Cashew, Pecan nut, Brazil nut, Pistachio nut, Macadamia nut Queensland nut, Mustard and Sesame seeds Process, chemical, enzymatic: Venkatachalam et al. (2002) [ 726] show that binding to rabbit monoclonal antibodies and to human IgE partially survives roasting, blanching, autoclaving, and microwave heating. Binding to the 39 kDa to 66 kDa bands is more stable than to the lower Mr. bands.The alert from Allergy UK states: "We understand that products in the Nivea sun protection range for kids now include almond oil. We have received calls to our helpline and comments on social media. These patients react primarily to a heat-stable protein (LTP) present mainly in Rosaceae but also in most other plant-derived foods. LTP is a widely cross-reacting allergen. Most LTP-allergic subjects have a history of peach allergy (OAS and/or more severe reactions), and about 25% report reactions eating almonds. Allergy to other tree nuts is possible in these patients. LTP is heat-stable and resistant to digestion in the stomach; as a consequence allergic patients may potentially experience severe allergic reactions.

Sathe et al. (2001) [ 730] used 13% acrylamide 1D gels for separation. Samples were reduced with beta-mercaptoethanol and heated.Today, Friday, Allergy UK - the leading national patient charity for people living with all types of allergy - also issued an alert over the products following a number of calls to its helpline from concerned parents. Tree nuts are considered as one of the most frequent causes of food allergy, but almond allergy seems rather unusual. No good data for occurrence of almond allergy are available. In the United States and in the United Kingdom the frequency of tree nut allergy as a whole is estimated to range between 0.2% and 0.5% both in children and in adults. Tree nuts allergies appear early in childhood, but in Mediterranean countries sensitization to heat-resistant proteins may appear in adults. It is presently unknown whether allergic patients may become tolerant after some years of avoidance.
