The immune defensive mechanism in parasitic infection with eosinophilia

This study was attempted to assess the extent of stimulation of the immune system in some patients suffering from parasitic infection with eosinophilia. Eighty-eight cases were selected, they included 10 apparently healthy, 10 suffering from different atopic disorders associated with eosinophilia and free from parasitic infections and 68 patients suffering from different parasitic infections associated with marked eosinophilia. The results showed a highly significant increase in the absolute eosinophil count in the atopic group while the parasitized group showed a moderate increase. The IgE serum level was increased in both atopic and parasitized groups. The cellular immunity expressed by phagocytic power of neutrophils was more depressed in parasitized than atopic group.
