[Spontaneous IgE production in asthmatic children].
In this study, we demonstrated spontaneous IgE production by peripheral blood mononuclear cells of asthmatic children. In 26 asthmatic children, the level of spontaneous IgE ranged 0.1-15.0 IU/ml and in 5 healthy normal children showed under 0.051 IU/ml. In 5 of asthmatic children, specific antibody of Dermatophagoides farinae was detected from PBMC by CAP RAST. In healthy normal children, specific antibody of Df was not detected. Spontaneous IgE production by PBMC and serum IgE level showed well correlation (gamma = 0.835, p < 0.001). Spontaneous IgE production and specific antibody of Df by PBMC also showed well correlation (gamma = 0.717, p < 0.001) IgE production of asthmatic children was inhibited by IFN-gamma.
