[Allergy to Hymenoptera venom. The value of allergen-specific IgG in therapy]

Between October, 1979 and December, 1982, Reless-hymenoptera venom was given to 70 patients to hyposensitize them. In 23 patients who during this treatment were subjected to a provocation test with a bee or wasp sting no systemic reaction occurred. At the time of the provocation test these patients had a wide scatter of antigen-specific IgG serum levels, between 34 and greater than 1000 U/ml. The IgG level was dose- and age-dependent. Demonstration of specific IgG levels alone does not make it possible to assess the success of the hyposensitization regimen.
