Timothy Grass Pollen Sensitization in Asthmatic Egyptian Children

Abstract

This analytical cross sectional study was conducted on children with bronchial asthma following up at the Pediatric Allergy and Immunology Clinic, Children's Hospital, Ain Shams University in the period from September 2017 to March 2018. Our aim was to investigate sensitization to Timothy grass pollen (TGP) in a group of asthmatic Egyptian children in relation to other markers of disease expression. The study included 100 asthmatic patients. Their ages ranged from 72-144 months with a mean age of 105.36 ± 25.33 months. Boys comprised 66 children (66%) while females were 34 (34%). Patients with asthma alone represented 10 (10%), while patients with asthma with concomitant other allergies represented 90 (90%) of our population, 88 (88%) of them had concomitant allergic rhinitis, 30 (30%) had concomitant urticaria/angioedema, 2 (2%) had concomitant eczema. Patients with intermittent asthma in this study represented only 16 (16%) while patients with persistent asthma represented 84 (84%) of our population.
