Bronchial responsiveness to bakery‐derived allergens is strongly dependent on specific skin sensitivity

Background: Quantitative relationships between immunological reactivity, non‐specific bronchial responsiveness and bronchial responsiveness to allergens have scarcely been investigated in occupational asthma. Methods: We assessed the above relationships in 24 subjects with baker's asthma. The skin endpoint titration to bakery allergens as a measure of immunological reactivity, together with the methacholine PC 20 and allergen PC 20 during early...
