Summary The immunological response to individual bee‐venom allergens was studied in blood samples collected at frequent intervals from four bee‐venom allergic patients who had suffered systemic allergic reactions to injections of bee venom during immunotherapy. All had high IgE antibody levels, at the upper end of the range found in bee‐sting allergic patients, and all had antibodies to the minor allergens at the time of the reactions. These did not, however, provide a simple explanation for the reactions that occurred. We were able to observe two interesting phenomena — in one patient IgE antibodies to the individual venom antigens appeared to be ‘switched off’ sequentially. In another, IgE antibodies to hyaluronidase rose substantially after 4 years of therapy. We believe that these results provide evidence to support the view that the regulation of IgE antibodies is controlled by mechanisms that are both isotype‐ and antigen‐specific.
