Abstract:
Objective To investigate the changes of serum immunoglobulin E(IgE)?T cell subgroups and cytokines in asthmatic children and to provide theoretical basis for the management of asthmatic children.Methods T cell subgroups were determined by indirect immuofluorence method mono clone antibody, the detection of IgE,interleukin(IL) 4,IL 6,IL 8,interferon ?(IFN ?) were done by ELISA method, and 20 normal children were served as control group.Results There were significant differences of CD3 +,CD4 +,CD4 +/CD8 + among the stages of exacerbation and convalescence of asthmatic children and control group.( P0.05).In the stage of convalescence the levels of IL 2,IFN ? were lower than control group( P0.05).Conclusions Allergic asthmatic patients between the exacerbation and convalescence stages still had immunologic imbalance,indicating increased number of CD4 +T cell(mainly Th2 cells)and hyperfunction;the insufficient number and(or) the inactivity of CD8 +T cell may induce immunological disturbance ,which is the major mechanism of asthmatic attacks. These findings suggest the patients in an abnormal immunological state should receive continuous anti allergic therapy.
