[Clinical and biological surveillance after the cessation of Hymenoptera venom desensitization]. / Surveillance clinique et biologique après arrêt de la désensibilisation aux venins d'hyménoptères.

107 patients have discontinued Hymenoptera venom immunotherapy between 1988 and 2000. 31 have been seen again with intradermal tests with IgEs, and 81 responded to a questionnaire. Intradermal reactions and IgEs decrease together significantly during immunotherapy and then persist at low level during three years. Beyond, the number of patients is insufficient. 32 patients were stung by the same Hymenoptera and not had any systemic reaction. However, five have beta blockers, three have IEC and half of the patients don't take precautions to avoid Hymenoptera.
