Pattern of Allergen Sensitivity among Patients with Allergic Rhinosinusitis in North-East India

Abstract

Abstract Introduction: The distribution of allergens varies among various geographical areas of India and the knowledge of allergen sensitivity pattern in North-East India is limited. These data can provide clinically useful information and better understanding of common allergies prevalent in this area. Aim: The aim of the study was to study the pattern of allergen sensitivity among patients with allergic rhinosinusitis. Materials and Methods: In this retrospective study, patients diagnosed with allergic rhinitis who underwent skin prick testing were included in the study. Patients who had taken drugs that could affect the test results, within 1 week before testing were excluded. Furthermore, patients on long-acting oral antihistamines within 4 weeks of testing and pregnant women were excluded. A total of 42 antigens were used which included three types of dusts, 14 types of pollens, 7 types of fungi, 2 types of animal dander, and 16 types of food items. Skin prick testing was done as per standard protocol. Results: Out of 100 patients, 53 (53%) were males and 47 (47%) were females. Overall, the highest percentage of skin prick test positivity was found for Dermatophagoides pteronyssinus dust mite (63%), Hen’s Egg (43%), Aspergillus fumigatus mold (32%), and Ragweed pollen (27%), in that order. Conclusion: Our study will be useful in providing information on the pattern of allergen sensitization in North East India.
