Abstract

Background The major birch pollen allergen Bet v 1 cross-reacts with homologous food allergens, resulting in IgE-mediated oral allergy syndromes (OASs). To avoid this food, allergy allergologists and guidebooks advise patients to consume birch pollen-related foods after heating.Objective We sought to evaluate whether cooked Bet v 1-related food allergens induce IgE- and T cell-mediated reactions in vitro and in vivo.Methods Recombinant Bet v 1, Mal d 1 (apple), Api g 1 (celery), and Dau c 1 (carrot) were incubated at increasing temperatures. Protein structures were determined by means of circular dichroism. Mediator release was tested in basophil activation assays. PBMCs and Bet v 1-specific T-cell lines with known epitope specificity were stimulated with native and cooked food allergens. Patients with birch pollen allergy who experienced OAS and the exacerbation of atopic dermatitis (AD) on ingestion of fresh apple, celery, or carrot were retested in double-blind, placebo-controlled food challenges with the respective foods in cooked form.Results In vitro, cooked food allergens lost the capacity to bind IgE and to induce mediator release but had the same potency to activate Bet v 1-specific T cells as native proteins. In vivo, ingestion of cooked birch pollen-related foods did not induce OAS but caused atopic eczema to worsen.Conclusion T-cell cross-reactivity between Bet v 1 and related food allergens occurs independently of IgE cross-reactivity in vitro and in vivo. In patients with AD, the resulting immune reaction can even manifest as late eczematous skin reactions. Therefore the view that cooked pollen-related foods can be consumed without allergologic consequences should be reconsidered.Clinical implications Symptom-free consumed pollen-related food allergens might cause T cell-mediated late-phase skin reactions in patients with pollen allergy and AD.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Some patients in that study manifested a late eczematous skin reaction, likely T-cell-mediated.

    “However, some patients did manifest a late eczematous skin reaction, which was likely T-cell–mediated (Table X.E-2).”

    From International Consensus Statement on Allergy and Rhinology: Allergic Rhinitis (2018) · cites this paper as [1922]

    Experimental — accuracy not yet measured
  • In one study, cooked apple, carrot, or celery did not cause oral allergy symptoms in patients with atopic dermatitis and birch pollen allergy who had oral allergy syndrome and dermatologic symptoms upon ingestion of the raw foods.

    “Cooked versions of the offending foods did not cause oral allergy symptoms.1922”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
