Since contact with them may cause or accelerate sympotoms in allergic patients. Our purpose of this study was to determine sensitivity to common allergens by skin prick test. Materials and Methods: Patients with allergic rhinitis, asthma and atopic dermatitis referred to Allergy Clinic of Valie Asr Hospital of Zanjan City, ۲۰۰۳-۲۰۰۵, were submitted to skin prick test with a series of indoor, outdoor and food allergens. Results: Two hundred patients (۱۱۱ females and ۸۹ males) ۴-۶۰ years of age were recruited. Eighty three percent of subjects showed at least one positive skin prick test. The skin prick tests were positive for grass (Rye grass ۴۱%), weed (pigweed ۲۷%, Herb ۲۱%), Tree (olive ۲۲%, Ash ۲۰%, Butirytis ۱۹.۵% ), Mites (D.P ۱۶%, D.F ۱۶%), Cockroach ۱۴.۵%, feather۱۱%, Mold (Aspergillus ۱۱.۵%, Alternaria ۷.۵%), Food (Wheat ۹%, Pepper۷.۵%, Egg ۶.۵%). Conclusion: According to the freguency of positive skin tests to pollens in our patients, it seems that avoiding contanct with these agents in related seasons, treatment ineluction, drug dose acceleration and desensitization procedures would be of great help in allergic patients.
