Eleven patients with a history of anaphylaxis, positive reactions to skin tests, and specific IgE antibody to wasp venom underwent hyposensitisation in a six hour procedure. No general reactions occurred. Complement activation and proteinuria could not be shown. The patterns of specific IgE, IgG1, and IgG4 were as described in other procedures--namely, IgE increased sharply and then decreased; IgG1 and IgG4 increased steadily and then decreased--but increase and decrease came earlier. Challenge by a stinging insect at least four weeks after treatment proved complete protection. The skin reactivity two years later showed an unpredictable pattern.
