Skin Prick Test Reactivity to Common Allergens among Allergic Rhinitis Patients in Kocaeli Province, Turkey

Abstract

Objective: The identification of the most common aeroallergens causing allergic rhinitis (AR) in a specific geographic area is important in the diagnosis and treatment of AR. This study evaluates the prevalence of sensitivity to aeroallergens among patients with AR who live in Kocaeli province, Turkey. Methods: This cross-sectional, descriptive study included a retrospective review of skin prick test (SPT) results from patients with suspected AR who were examined at a tertiary hospital rhinology clinic. Results: The SPT results of 85 patients with an AR diagnosis were included in this study. House dust mites (HDM) had the highest frequency of positive test responses (57.6%), followed by tree pollen (40.0%), grass pollen (36.5%), weed pollen (32.9%), cockroach (18.8%), animal dander (14.1%), and mold (11.8%). The majority of the AR patients were polysensitized (57.6%), and the most common allergens in polysensitized patients were tree pollen (61.2%), grass pollen (57.1%), and HDM (55.1%), respectively. The strongest single allergen in monosensitized subjects was HDM, with a rate of 61.1%. Conclusion: The most prevalent allergen was HDM among AR patients in the Kocaeli region, followed by tree pollen and grass pollen. Polisensitization occurs more frequently than monosensitization. These allergens should be prioritized in the diagnosis and treatment of allergic rhinitis in Kocaeli region patients.
