Skin prick test reactivity to aeroallergens in Jordanian allergic rhinitis patients

Identification of the most common aeroallergens to which patients are sensitized in a specific area is important in the diagnosis and treatment of allergic rhinitis. The aim of this cross-sectional study was to investigate the pattern of skin prick test reactivity to various aeroallergens among allergic rhinitis patients attending outpatient clinics in Amman, Jordan. Skin prick test with 18 standardized allergen extracts was performed on 538 patients. Most allergic rhinitis patients in the study sample had polysensitization. Grasses mix (51.4% of patients), thistleweed (46.9%) and olive tree (45.3%) pollens were the most common allergens in this group of patients (all seasonal). Cat allergen was the most common perennial allergen (41.6%), followed by dust mite Dermatophagoides pteronyssinus (32.9%). These allergens should be given the highest priority when educating allergic rhinitis patients in Amman regarding allergen avoidance strategies.
