Allergy to venom from bee or wasp: the relation between clinical and immunological reactions to insect stings

Sixty-three patients, applying to the casualty ward after a bee or wasp sting, were tested. On the day of admission, and 4 weeks later, blood was sampled to measure specific IgE and IgG against bee and wasp venom and total IgE. Four weeks after the insect sting, all patients were examined with skin-prick test (1, 10 and 100 micrograms/ml), and intracutaneous test (0.05 ml of extract 1.0 microgram/ml). The amount of venom-specific IgE and IgG increased significantly during the 4-week period, venom-specific IgE was most pronounced in patients experiencing the most severe clinical reactions. However, no significant correlations were found between the results of the immunological tests carried out 4 weeks after the insect sting and the clinical reaction upon the insect sting.
