Objective: To determine the serum levels of eotaxin, IL-13 and total IgE (TIgE) in asthmatic children during the acute and clinical remission periods, as well as the changes in pulmonary function to determine their roles, relationships and clinical significance during asthma exacerbation.
Methods: A total of 30 asthmatic children and 22 healthy children were enrolled in the study. The serum eotaxin and IL-13 levels were detected using an enzyme-linked immunosorbent assay and the TIgE level was detected using a fluorescent enzyme-linked immunosorbent assay. The asthmatic children were subjected to pulmonary function tests.
Findings: The serum eotaxin, IL-13 and TIgE levels of the asthmatic children during the acute period significantly differed from those during clinical remission. The serum eotaxin, IL-13 and TIgE levels of the asthmatic children during both periods significantly differed from those of healthy children (P<0.001). The serum eotaxin levels during the acute and clinical remission periods were positively correlated with serum IL-13 and with TIgE, and serum IL-13 was correlated with serum TIgE. The pulmonary function indices of asthmatic children during the acute period significantly differed from those during clinical remission (P<0.001). The serum eotaxin and IL-13 levels in the asthmatic children were positively correlated with the forced expiratory volume in 1 second (FEV1) and the peak expiratory flow (PEF) during the acute and clinical remission periods (P<0.05). However, the serum TIgE levels in asthmatic children were not significantly correlated with the FEV1 and PEF during both periods (P>0.05).
Conclusion: Serum TIgE, IL-13 and eotaxin influence each other during exacerbation of bronchial asthma and influence the corresponding pathophysiologic changes. Serum IL-13 and eotaxin could be used as markers for evaluating the severity of bronchial asthma.
