Prevalence of common inhaled allergies in Erbil province, Kurdistan Region of Iraq

Nowadays, inhaled allergens are the main causes of allergic diseases, which are derived from different sources such as animal dander, grasses, tree, insects and fungi/molds. Identification and detection of allergens play a critical role in the diagnosis and treatment of many allergic diseases. Aims were to determine the prevalence of most common inhaled allergens in Erbil province and determination the intensity of allergic response among allergic patients against 35 identified inhaled allergens items. A total number of 170 patients suffering from suspected inhalant allergy were checked in the present study. The study was carried out for patients who visited the private clinical sectors between 2018-2020 in Erbil province, Kurdistan Region of Iraq. Determination of specific IgE (sIgE) antibodies was examined for suspected patients. The country-specific inhaled allergy profile “Euroline inhaled Iraq 1” (Catalog no: DP 313816011 E, IVD approved, and CE certified EUROLINE immunoblot), containing strip for 35 different inhalant allergens, has been used in this study. Positive specific IgE to inhaled allergens was detected in 22.35% of our suspected patients. Orchard grass (21.05%) was the most inhaled allergen in our 38 allergic patients, followed by the Meadow foxtail (15.78%), Cockroach German and Sweet vernal grass (13.15%). Based on the present study results, we conclude that the prevalence of inhaled allergy differed between men and women in different age groups. Our study reached that there were no associations between inhaled allergens and sex or age. DOI: http://dx.doi.org/10.5281/zenodo.4395149
