Sensitivity to hymenoptera in adult males

The authors studied the sera of 86 selected adult male office workers for IgE antibodies to yellow jacket and honey bee venoms and to environmental inhalants and foods. Structured histories provide information about the experiences of these men with the Hymenoptera and other immunological information. Three men (3%) gave a history of a local or general reaction to the Hymenoptera but no antibodies were detected. Ten men (12%) had IgE antibodies to yellow jacket or honey bee venoms but none gave a history of a reaction. Nine of these men were atopic. The authors speculate that IgE antibodies to the Hymenoptera in atopic adult males may be more common than is currently recognized.
