Abstract/Text In ongoing studies of the natural history of stinging-insect allergy, 133 patients with large local reactions have been evaluated over 8 yr; 79 patients returned for reevaluation. Based on RAST analysis with honeybee and vespid venoms, patients were divided into RAST-positive and RAST-negative groups. Sixty-six patients were RAST-negative with positive venom skin tests in 58%. Seventy-five testings in this group led to no systemic reactions and 74 large local reactions. At follow-up RASTs remained negative, and the incidence of positive skin tests was unchanged. Sixty-seven patients had detectable serum venom-specific IgE covering a wide range in antibody titers, indistinguishable from patients with systemic reactions. Twenty-four of 67 patients received venom immunotherapy (VIT). RAST titers decreased similarly in the VIT and untreated groups. There were 55 testings resulting in 40 recurrent large local reactions occurring in equal incidence in treated and untreated patients. One systemic reaction occurred in an untreated patient. In reviewing 118 patients with sting anaphylaxis, a previous large local reaction occurred in five. These results suggest that after repeat stings, patients with large local reactions tend to have subsequent large local reactions, regardless of the presence of venom-specific IgE or immunotherapy. There is small risk of anaphylaxis. Determination of serum venom-specific IgE by RAST or skin tests does not aid in treatment or in predicting prognosis. Thus skin tests are not necessary in patients who have had large local reactions, and venom immunotherapy is not indicated.
