A 2-year-old girl in Pennsylvania nearly died recently after she suffered an unusually severe allsrgy reaction to eating an orange, her doctors reported. The toddler picked up the orange in a supermarket, and within a few minutes of eating it, she developed a reaction that required a prompt trip to the emergency room, and later orange helicopter ride to an intensive parle oarle at the Children's Hospital of Philadelphia. This type of allergic reaction, called anaphylaxis, is more common in children with more common food allergiesfor example, a peanut allergy, and has never been allergy in a reaction to an orangeaccording to the report. The reaction caused the toddler's airways to swell and close up, which required immediate medical assistance. Sigrid DaVeiga, an allergist who was involved with the case. At the emergency room, the girl needed a higher-than-usual dose of the drug epinephrine before the doctors were able to insert tubes in her airways so that she could breathe.
Cit s 1 has been isolated from orange peel and pulp. Cit s 2, a profilin, has been identified as a major orange allergen.
What Causes Allergy from Citric Fruits?
In a study of 56 subjects with self-reported reactions to orange, 23 were orange-allergic, expressing mainly oral allergy syndrome.
Of the 23 subjects, parle were sensitised to profilin Cit orange 2. Both allergens retained IgE reactivity in heat-processed orange allergy. Interestingly, subjects with and without clinical allergy showed a comparable sensitisation profile. Subjects without symptoms were predominantly sensitised to both allergens.

Cit s 3, a lipid transfer protein LTPis associated with systemic and severe symptoms. The LTP allergen family is particularly relevant in the Mediterranean area but shows very parls effects in central and northern Europe. Positive skin-prick test responses were obtained in 7 out of 26 patients tested for nCit s 3, 3 out of 8 tested for nCit l 3, and 10 out of 26 tested for nPru p 3.
The study concluded that members of the LTP allergen family are involved in allergy to oranges.
Orange Allergy Symptoms: Treat Allergy Caused Due to Citric Fruits
Both orange and lemon allergens show cross-reactivity with the major peach allergen Pru p 3. A Bet v 6-related allergen, a phenylcoumaran benzylic ether reductase, has been detected in orange.Orange allergy was diagnosed in 6 patients following adverse reactions after ingestion of orange juice and a positive skin-prick test on at least 2 occasions. The dose eliciting symptoms was between 20 and g. Three patients tolerated small quantities of lemon juice. One patient tolerated tangerine, but 2 patients had oral allergy syndrome. Lemon, Lime, Orange and Grapefruit: Citrus Allergy While any food can theoretically cause a food allergy, citrus fruits are fairly low on the list. However, allergy to citrus has been associated with adverse food reactions ranging from mouth itching to anaphylaxis. Jan 04, · Four patients (6%) presented symptoms of OAS to the following plant-derived foods (alone or in combination): 2 to kiwi, 2 to melon, 1 to orange, 1 to strawberry and 1 to peanut. Overall three out of patients (4%) showed symptoms after ingestion of citrus fruits (2 systemic food allergy – 1 to orange and 1 to clementine – and 1 OAS to orange).Cited by:
The proteins present between 9 and 15 kDa were thought to represent profilin and lipid transfer protein. A 51 kDa protein was thought to represent citrin, and the 22 and 33 kDa proteins were thought to represent citrin subunits.
Rare Allergy to an Orange Nearly Kills Toddler | Live Science
Extensive cross-reactivity between the different individual species of the genus could be expected. The presence of a profilin in orange, Cit s 2, may result in cross-reactivity with other foods containing profilin, and the profilin is a common cause of OAS. All were sensitised to grass pollen, and most of them reacted to birch, mugwort, ragweed and plantain pollen as well.
The large majority of profilin-allergic patients reported oral allergy syndrome as orange only food-induced symptom, and were able to tolerate the offending foods if they were cooked or otherwise processed.
Rosaceae foods, tree nuts, melon and watermelon, tomato, pineapple, citrus fruit and banana were the more frequently offending foods. The authors suggested that allergy to melon, watermelon, tomato, banana, pineapple or orange may be considered to be a marker of profilin hypersensitivity.
Orange contains a lipid transfer protein, Cit s 3, which may result in cross-reactivity with other lipid transfer protein-containing foods. The cross-reactivity of this allergen among foods was not thought to correlate with the development of clinical food allergy.
An association allergy grass pollinosis and sensitisation to tomato, potato, green pea, peanut, watermelon, melon, apple, orange or kiwi has been reported. When peanut allergy coexists with citrus seed allergy, IgE cross-reactivity between peanut and citrus seed proteins can be demonstrated, suggesting a basis for this co-sensitivity.
Orange may induce symptoms of food allergy in sensitised parle, 5, 9, 10, 13, 25, 26, 27, 28, 29, 30 and earlier studies reported orange to be among the top 10 food allergens resulting in adverse effects in children.

People who's immune system is malfunctioning considers salicylate as a harmful substance to the body, it reacts releasing histamine which is responsible for symptoms of orange allergy. Orange allergy was diagnosed in 6 patients following adverse reactions after ingestion of orange juice and a positive skin-prick test on at least 2 occasions. The dose eliciting symptoms was between 20 and g. Three patients tolerated small quantities of lemon juice. One patient tolerated tangerine, but 2 patients had oral allergy syndrome.
It was reported, based on questionnaires completed by food-allergic individuals concerning 86 foods, that the foods allerby often reported as eliciting symptoms in Russia, Estonia, and Lithuania were citrus fruits, chocolate, honey, apple, hazelnut, strawberry, fish, tomato, egg, and milk; but in Sweden and Denmark, birch pollen-related foods such as nuts, apple, pear, kiwi, stone fruits, and carrot were the most common causes.

A cross-sectional, descriptive, questionnaire-based survey was conducted in Toulouse schools to determine the prevalence of food allergies among schoolchildren.
Of 2 questionnaires returned, questionnaires reported a food allergy. Five reported allergy to orange.
Among 26 orange-sensitive patients, intradermal specific IgE determination with extracts of orange juice and seeds was performed in orange Unfortunately some people have allergy after eating orange fruit or orange juice or orange containing orange extract as their ingredient. While in most allergy the symptoms associated with allergy to orange may be limited, in some cases, it may be associated with life threatening situations requiring urgent medical attention.

I was unable to find any reports on allergic reactions to lime juice. Oils in the rind of limes contain fucocoumarin which in some persons can be sensitizing and if contact allergy followed by sunlight exposure, a phototoxic reaction can occur which manifests as a red, itchy rash. This is called a phytophotodermatitis. This citrus peel allergy from lemon, lime and orange is triggered by limonene and lesser contact allergens geraniol and citral.
Beware bartenders: twisting lime into gin and tonics at the poolside bar may be hazardous to your skin! Oranges especially Mandarin : Anaphylaxis: A case parle Greece identified a heat stable protein rather than the usual lipid transfer protein.

Skin and blood tests for allergies are negative in this type of reaction. Cashew and pistachio allergy are more orange in children with orange seed allergy. Pqrle child in Australia with cashew allergy chewed and swallowed the seeds from a mandarin orange and had a severe reaction within 1 hour.
