Background and Aims: Allergic disorders such as asthma, urticaria, eczema, and allergic rhinitis are common worldwide, and allergens are the most common etiology and exacerbating factors. So, This study aimed to find the allergens in these patients with skin prick tests.
Materials and Methods: All the allergic cases referred to an allergic clinic in the north of Iran were visited by an allergist and clinical immunologist. Based on patient history, physical examination, and diagnosis, we select food allergens and aeroallergens. A standard skin prick test was performed on all patients, and all data was then analyzed SPSS 20.
Results: Two thousand one hundred and twenty-eight cases entered the study with a mean age of 27.65 ± 15.52 years old. 1235 (58.04%) females and 893 males (41.96%) participated in this study. Prevalence of allergic rhinitis, asthma, urticaria, and eczema were 717 (33.7%), 611 (28.8%), 550 (25.8%), and 250 (11.7%), respectively. The most common aeroallergens were Dermatophagoides farinae (75.9%), Dermatophagoides pteronyssinus (65.4%), feather (56.1%), and Candida (51.1%), respectively, in all patients. The most common food allergens were egg white (31.1%), cacao (29.7%), and egg yolk (28.9%), respectively, in all cases.
Conclusion: Both aeroallergens and food allergens were the most common in all allergens by skin prick test. Therefore, it is important to find the relationship between sensitization and allergy.
