Atopy Patch Test to <i>Dermatophagoides</i> Mix in a Self-selected Population in Beijing
Bibliographic record
Abstract
BACKGROUND: Dermatophagoides is one of the most common inhalant allergens in the pathogenesis of atopic dermatitis (AD). The prevalence of atopic patch test (APT) to it in the general population, however, is largely unknown. OBJECTIVES: The aim of this study was to detect the frequency of APT to Dermatophagoides in a self-selected population in Beijing. METHODS: Healthy university student volunteers were recruited and patch tested with a commercial Dermatophagoides (pteronyssinus/pharinae) mix. RESULTS: Of 201 students studied, 25.9% exhibited positive results. The positivity rate was not correlated to gender but increased with age. In volunteers without eczema, allergic rhinitis, or asthma, the positivity rate of APT was as high as 13.6% but is much lower than that of volunteers who had allergic rhinitis or asthma (56.1%, P < 0.05, χ2 test). One volunteer had AD and was tested positive, but only 27.3% of those who had other types of eczema but without allergic rhinitis or asthma were tested positive. CONCLUSIONS: This study confirmed that APT to Dermatophagoides mix is highly related not only to AD but also to respiratory allergy. The high positivity rate of APT in volunteers without eczema or respiratory allergy implied that a large number of positive APTs in patients with AD may be not relevant.

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.
