The Evolution of IgE-Based Allergy Testing in Atopic Dermatitis: Where Do We Stand?
Bibliographic record
Abstract
The pathophysiology of atopic dermatitis (AD) involves cutaneous inflammation, predominantly mediated by innate immunity and T cells, in which IgE has a marginal role in most patients. Over previous decades, however, there has been an ongoing debate regarding the relevance of IgE-mediated allergy testing in patients with AD. Patients with AD have a defective skin barrier that facilitates a high inflammatory response to environmental antigens, placing them at greater risk for food allergies. Nevertheless, because these patients often produce high levels of IgE, the positive predictive value of skin prick tests and specific IgE measurements is low; such tests should be performed only when there is a concordant immediate hypersensitivity reaction (ie, urticaria or angioedema) rather than eczema. In recent years, numerous studies have emphasized the importance of maintaining oral exposure to foods to prevent the development or progression of food allergies in atopic patients. Although it is acknowledged that food allergens may contribute to AD in certain cases, it is critical that patients understand the risk of developing IgE-mediated food allergies if they exclude allergenic foods from the diet. Ultimately, controlling AD while retaining these foods in the diet should be the goal for all patients.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
