TI  - Pollen sensitization among Egyptian patients with respiratory allergic diseases.
PG  - 1-11
AB  - Pollen is responsible for seasonal allergies, such as allergic 
      rhino-conjunctivitis (AR), and has become a growing public health concern. 
      Climate change affects the range of allergenic species as well as the timing and 
      length of the pollen season. In Egypt, data on pollinosis are scarce. This study 
      aimed to identify the most prevalent pollen causing allergies among Egyptian 
      patients with respiratory allergies. A total of 200 patients with respiratory 
      allergic diseases, allergic rhinitis and/or bronchial asthma (BA), were included. 
      Medical history taking and physical examinations were conducted on each patient. 
      Complete blood count (CBC), total immunoglobulin E (IgE) determination, 
      spirometry, specific IgE, and skin prick tests (SPTs) for common aeroallergens 
      and food were performed. Of the 200 patients, 106 (53%) were females. The age of 
      study subjects ranged 16-66 years (mean +/- SD, 34.42 +/- 13.0), and 65% were living 
      in urban areas. Grass pollen, mainly from Timothy grass and maize, were the most 
      prevalent allergens (28.5%). Timothy grass was the most common type of pollen in 
      patients with AR (28.3 %). Elder pollen was more prevalent among asthmatic 
      patients (P = 0.004). Bermuda grass was statistically more prevalent in rural 
      than in urban areas (P = 0.008). Maize was linked to uncontrolled BA, whereas 
      Timothy grass was the most prevalent among patients with moderate/severe AR. 
      Forty-three patients had oral allergy syndrome; oranges and tomatoes were the 
      most cross-reactive food allergies (12% and 11.5%, respectively). Exacerbation of 
      allergic symptoms was noted during January, December, March, and June. In 
      conclusion, pollen plays a substantial role in affecting patients with 
      respiratory allergies in Egypt. Grass pollen is the most prevalent type of 
      pollen, especially in urban areas.
