Background and aims Allergic Rhinitis is a fairly common allergic disease among children that significantly affects quality of life as well as school performance. Frequently coexists with asthma.

The aim of our study was to assess the sensitisation to inhalant allergens among children with allergic rhinitis.

Methods We included in our study 205 children, 118 boys and 87 girls, followed at the outpatient clinic of our hospital and aged (MEAN ± SD) 6.03 ± 4.18 years. A questionnaire regarding asthma, allergic rhinitis and atopy was used, along with standard clinical and laboratory assessment. Radioallergosorbent assay test (RAST) was used to identify allergen – specific IgE for common aeroallergens (a concentration of specific IgE > 3.5 KU/L was considered positive). For the statistical analysis we applied SPSS 20.0 (IBM Corp.), chi-square and Fisher’s exact test.

Results Children with allergic rhinitis had more often positive RAST for Olive (p < 0.001), Altenaria (p < 0.001), and Dust Mites (p < 0.001). Additionally, children with allergic rhinitis also had more often asthma (p < 0.003).

Conclusions Often exposure to allergens such as olive, dust mites, Altenaria, that are common in the environment, is unavoidable. The positive identification of the aeroallergen that is responsible for allergic rhinitis symptoms is of great importance for choosing the right therapeutic approach.
