Pitaya allergy: a case report of anaphylaxis in a patient without cross-reactive allergens
Bibliographic record
Abstract
BACKGROUND: Pitaya, commonly known as dragon fruit, is increasingly available and has allergenic potential. Pollens have been found to have cross-reactivity and thus induce allergies to several fruits, however, to our knowledge this is first report of pitaya anaphylaxis in a patient without co-sensitization to other fruit or environmental allergens. CASE PRESENTATION: A 26-year-old male presented to the emergency department with anaphylaxis after consumption of pitaya (dragon fruit). He had no prior history of atopy. Epicutaneous skin testing demonstrated positive to pitaya and negative to all other cross-reactive food and environmental allergens, suggesting his pitaya allergy did not derive from cross-sensitization. CONCLUSIONS: Our case is unique in demonstrating the potential for pitaya allergy to occur independent of other allergies and cross-sensitization. Future research is warranted into suspected allergenic proteins in pitaya and quantifying their structural similarity to other known allergens.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
