Background: Allergic disorders, particularly bronchial asthma, are one of the most common chronic childhood diseases. Bronchial asthma is more prevalent among children of the Eastern Province of Saudi Arabia compared with the other provinces. Environmental factors play major roles in the disease pathogenesis in genetically predisposed hosts. In this study, we characterize the pattern of allergenicity in asthmatic children in the Eastern Province of Saudi Arabia. Materials and Methods: This study is a retrospective, cross-sectional analysis of skin sensitization profiles of 100 Saudi asthmatic children living in Al-Khobar, Saudi Arabia. The group compromised 32 females and 68 males, aged 5–14 years with a mean age of 8.98 ± 2.93 years. Skin prick tests were performed in a regional tertiary center, in the period between January 2011 and December 2012, using a variety of indoor and outdoor allergens. Results: The most common indoor sensitizing allergens found were the house dust mite (54%), cat fur (53%) and the German cockroach (26%). Among outdoor allergens, Salsola kali was the most common (48%), followed by Timothy grass (23%) and Chenopodium album (23%). Among trees, Prosopis glandulosa was found to be the most prevalent sensitizer (19%). Among the molds, Alternaria and Aspergillus species were the most prevalent (21% each). Conclusion: A high rate of sensitization to aeroallergens was found in asthmatic children living in Al-Khobar city. The pattern of sensitization found in our study reflects the newly altered nature of an ancient humid desert that has been influenced by the recent artificial modernization of the region.
