- Abstract
Two groups of children from 6 to 14 years old have been compared to explain correlation between haematic eosinophils and allergic respiratory diseases related with the environment where they live. First group was formed by 350 pupils of Sesto S. Giovanni, and industrialized town, the second group by 345 pupils of Cogliate, a country place. The screening was been preceded by a set of questions self-managed and it consisted in the determinations percentage of peripheral blood eosinophils. Patients whose eosinophils were more than 4% have been considered eosinophilia carrier. The results have been elaborated with statistical method "chi square". Results proved the greatest prevalence of allergic respiratory diseases in urban population with a greater eosinophilia spreading (33% in comparison with 26%; p less than 0.05). Eosinophilia appeared connected with recurrent rhinitis (p less than 0.001) relapsing bronchitis (p less than 0.001) relapsing bronchitis (p less than 0.001) asthmatic bronchitis (p less than 0.001) positive results of skin tests to 4 allergens (p less than 0.001) and in rural district also with male sex (p less than 0.05). In industrialized areas, in special way there is a closed relation between respiratory diseases and peripheral blood eosinophils increased. Eosinophilia will be find in relapsing respiratory pathology and it will apply to allergology controls. It could represent an unfavourable element of prognosis foresee the possibility that episodic bronchus-spasms will be frequent in patients with asthmatic syndrome.
