الوصف: Introduction Type-2 inflammation and bronchial epithelial injury play a pivotal role in the pathogenesis of allergic asthma (AA). Cytokines are crucial in orchestrating, perpetuating and amplifying the airway inflammatory response. Interleukin (IL)-4, IL-13 is deeply involved in immunoglobulin E synthesis, eosinophil activation, mucus secretion and airways remodelling, IL-25, IL-33, IL-8 appear to be sensitive to epithelial injury. There is a lack of data about these cytokines changes after contact with the inhaled allergen. Aim To investigate serum levels of cytokines IL-4, IL-8, IL-13, IL-25, IL-33 in acute AA. Methods We examined 16 patients: 8 steroid-free, stable, sensitized to Dermatophagoides pteronyssinus patients with AA and 8 healthy, non-atopic subjects (HS). Peripheral blood eosinophils were isolated using centrifugation and magnetic separation. Bronchial allergen challenge was performed using inhaled D. pteronyssinus (Diater, Spain) via a pressure dosimeter (ProvoX, Ganshorn, Germany). Cytokines levels in serum were measured by ELISA before allergen challenge (V1) and after 24 hours (V2). Results At the baseline (V1) patients from the AA group had significant higher eosinophil count (0.39±0.21 vs 0.17±0.10 x1012/l), serum levels of IL-4 (46.7±7.3 vs 11.3±2.2 pg/ml), IL-13 (889.1±177.5 vs 218.5±67.8 pg/ml) compared to HS (p<0.05). After allergen challenge test eosinophil count in AA significantly increased to 0.46±0.13 x1012/l; IL-4 - 62.8±7.3, IL-8 - 48.8±9.0, IL-13 - 1121.0±218.4, IL-25 - 63.5±13.1 pg/ml (p<0.05) without significant changes in HS.
