Abstract
Allergens cause different sign and symptoms in patients with allergic disorders. In order to
determine the common allergens among patients with allergic disorders in Zahedan City, center of
Sistan-Blouchestan province, this study was performed.
Eight hundred and ninety-four patients who referred to Immunology and Allergy Medical Center
of Khatam Hospital during 36 months period (2000-2003) was studied. Skin-prick tests (SPTs) to
common allergens were performed in all of the patients.
Eight hundred and ninety-four patients (382 male and 512 female), aged 2-70 years, had allergic
disorders. The most frequent allergic disease was rhinitis, seen in 481 patients (53.8%). The other
common disorders were asthma in 215 patients (24.1%), and urticaria in 137 cases (15.3%).
Among the SPT-positive patients, a positive prick test reaction to the house dust mites (86.4%),
Feathers (75.5%), and Aspergillus (51.1%) was most common, followed by Cladosporium (39.8%),
Alternaria (37.9%), Trees (37.7%), Penicillium (36.6%), Weeds (34.9%), and Fruits (31.2%). Also,
23.8% of the subjects were sensitized to Grasses in the prick test, Hen's egg (21.8%), Walnut (16.7),
Cow's milk (14.4%), Beef meat (11.6%), and Hazel nut (8.6%) accounting for other positive
reactions.
The prevalence of common allergens especially mite allergen is high among patients with
allergic disorders in Zahedan.
