One of the described sunflower allergens, Hel a 3, is a lipid transfer protein. One suspected risk factor for this allergy has been the ownership of household pet birds, ie the handling of birdseed containing sunflower seeds . Significantly elevated levels of antigen specific IgE against sunflower allergens were found in the patients’ blood serum.17, The first case of anaphylaxis associated with sunflower LTP sensitization was described in 2010. RAST inhibition tests were positive in two patients.13, The case was different with the third patient, occupationally exposed to sunflower pollen. Sunflower allergens on the whole, however, still await precise and systematic description. In what follows, we wish to present the case of a 40-year-old man admitted to the Department of Allergology, Immunology, and Internal Medicine due to dyspnea, wheezing, and skin lesions in the form of red wheals, which appeared after he ingested sunflower seeds.

Three patients had an anaphylactic reaction and one patient had a bronchial asthma attack. Mugwort pollen is one of the main causes of allergic reactions in Europe. Usually, peach LTP is the primary sensitizing allergen, with the highest concentration of allergen in the peel of the fruit. The seeds, surrounded by a hard-shelled pericarp, ripen between September and October. The occurrence of a specific IgE directed against LTP may suggest cross-reactivity with a variety of vegetables and fruits, because LTP is a plant panallergen. A detailed medical interview revealed that in August the patient experienced allergic symptoms in the form of nasal obstruction and rhino-rhea. Speak with a health specialist today. We then estimated the protein concentration in the extracts and used the samples at a 1 mg/mL concentration, allowing for their total protein content.

In comparison to the control group, the patients suffered from rhinitis and conjunctivitis significantly more often.16, An unusual case of oral allergy syndrome caused by sunflower was described in 2005 by Palma-Carlos et al. investigated cross-reactive behaviors of Art v 1 and identified cross-reactive structures in sunflower pollen.7. The lesions were located on the upper limbs, lower limbs, and the chest. The 13 kDa protein closely matched LTPs from sunflower seeds.18. A native prick by prick test with sunflower seeds was strongly positive (8/5 mm).

The aim of this study is to present an unusual case of a patient who experienced an allergic reaction to sunflower seeds in the absence of occupational or bird-related allergies. The levels of IgE directed against other allergen components available in ImmunoCap ISAC were not elevated. FundingThis research received no specific grant from any funding agency in the public, commercial, or not-for-profit sectors. She was treated with steroids and adrenaline with a good therapeutic effect. It was noted, however, that among bird breeders positive skin tests with sunflower allergens were observed Specific IgE-mediated hypersensitivity to sunflower seed was demonstrated by history, prick skin tests, positive passive transfer skin test… Have a question?

Among them, only three tested positive in a RAST inhibition test with sunflower allergens. Sunflower Seed (k84) IgE. Hel a 3 – a lipid transfer protein (called non-specific lipid transfer protein type 1 [nsLTP1]), non-specific, 9 kDa, a food allergen.6. Characteristically for sunflowers, the flower head consists of 1000–2000 disc florets, and spreads up to 60 cm in diameter (30 cm on average). wanted to determine the frequency of sunflower seed allergy. Turnaround time is defined as the usual number of days from the date of pickup of a specimen for testing to when the result is … Bird breeders are among professions especially predisposed to sunflower allergy. Sunflower seed hypersensitivity is sensitivity to sunflower seeds or their subsidiaries which cause an immune system response when in contact or potentially ingested. Moreover, through a laryngological examination we found swelling of the hypopharynx with retention of saliva, and swelling of the floor of the mouth and tongue. Microarray ImmunoCap ISAC test was also performed to determine the level of the allergen specific IgE against a wide set of allergen components. In the inhibition test Art v 1, Art v 3, and Jug r 3 were inhibited by the protein present in the sunflower seed allergen extract. The relatively rare use of adrenaline in treating anaphylaxis may be caused by a lack of in-depth knowledge about this treatment among health professionals.21, Due to the lack of availability of a standardized allergen extract of the sunflower allergen we used fresh seeds for the diagnostic prick by prick tests. None found for this test Please visit our Clinical Education Center to stay informed on any future publications, webinars, or other education opportunities.

Seed allergies are fairly uncommon. Based on our results and the clinical pattern of the disease we confirmed that the patient is allergic to mugwort pollen and that he had an anaphylactic reaction as a result of ingesting sunflower seeds. Sunflower seeds are a rare source of allergy, but several cases of occupational allergies to sunflowers have been described.

Axelsson et al 1994 suggest that the route of sensitization was probably by inhalation of airborne sunflower seed allergens as all four patients had kept cage birds fed on sunflower seeds. Sunflower allergens have so far been described relatively poorly. The levels of IgE directed against Art v 1, the main allergen of mugwort pollen, was high.
