Changes in the concentration of sIL-2R, IL-2 and ECP reflect increased T cell and eosinophil activity in relation to the level of severity of asthma in atopic and nonatopic children, thereby proving the presence of persistent inflammation despite the absence of disease symptoms.

CD4+CD25(high) T-cell proportion in the peripheral blood of total CD4+T cells is not reduced in children with allergic IgE-mediated asthma and does not differ between disease remission and exacerbation.
