[The influence of mononucleosis infection on atopic disease development in children].

The aim of the study was to determine whether infectious mononucleosis may trigger atopic symptoms or modulate their clinical course. Data from literature point out to such a relationship and attribute it to the influence of EBV on lymphocytes B and IL-4,IL-5,IL-10 and vIL-10 secretion stimulation. The authors examined 30 children who had suffered from symptomatic infectious mononucleosis 2-4 years previously, evaluating symptoms of allergic diseases and performing skin prick tests with selected inhalant and food allergens. The symptoms of atopic disease were found in 57 % in the mononucleosis group, a significantly higher percentage (p<0.0001) than in general population of children in Lódź (16%). The frequency of positive skin prick tests with common allergens was also significantly higher (60% vs 27%, respectively).
