Abstract/OtherAbstract:
BACKGROUND: Extension of the intervals at which maintenance venom immunotherapy (MVIT) is administered has been attempted for many years. However, published evidence on its effect, especially in intervals of longer than 3 months, is sparse. OBJECTIVE: To examine whether the administration of a bee venom (BV) maintenance dose at 6-month intervals is safe and efficacious. METHODS: The 3-month intervals at which venom-allergic patients were receiving their MVIT were gradually extended to 6 months. Systemic reactions (SRs) to immunotherapy injections or to field stings were regularly recorded. Patients who were allergic to BV alone or also to other venoms were deliberately sting challenged by a honeybee after reaching the 6-month interval. RESULTS: The 3-month intervals were extended in 47 patients. A single patient (2%) developed an SR after receiving the injection at an interval of 4 months. Two field stings in 2 patients resulted in a mild SR in 1 patient. Of 14 sting-challenged patients, 3 (21%) developed an SR after the challenge. The 3 SRs occurred only among the 8 patients (38%) who were allergic to BV alone. The 3 patients with the SR to the challenge continued to receive the regular maintenance dose at monthly intervals 3 to 5 more times. Repeated sting challenges were then well tolerated in all 3 patients. CONCLUSION: The administration of MVIT at 6-month intervals does not provide suitable protection in BV-allergic patients, and they should continue MVIT at the accepted 1- to 3-month intervals.
