RESUMO
The aim of the study was to evaluate the relationship between h.d.m. allergy and incidence of respiratory tract infections in children with episodic, mild and moderate asthma. 32 children with bronchial asthma being followed up at the I. Department of Children Diseases P.A.I.P. CMUJ in Cracow were included into the study. The positive skin prick test (SPT) with H.D.M. allergens was confirmed in 18 children. The negative SPT allergens were observed in 14 patients. All patients were examinated by the retrospective inquiry which included the degree of asthma, severity of therapy schedule and incidence of acute respiratory tract infections during the last 6 months. The anthropometric measurement (length, weight, body mass index, thorax circumference) and spirometric parameters with physical examination challenge were introduced. The mean number of infections in group of patients sensitive to H.D.M. was 6.8; in non sensitive group-4.6. There was no significant difference in incidence of acute respiratory tract infections between both groups. It seems likely that small number of patients may influence the statistics. To verify the results, prospective observation of wider group of patients is planned in forthcoming winter.
