Maintenance venom immunotherapy administered at 6-month intervals to bee-venom allergic patients failed to provide protection from systemic reactions after sting challenges. These patients should continue their immunotherapy at 1-3 month intervals.

Primary Outcome Measures:
  • whether the administration of bee venom (BV)
  • maintenance dose (MD) at 6-month interval is safe and
  • efficacious.

Estimated Enrollment: 60
Study Start Date: June 2004
Estimated Study Completion Date: May 2006
Detailed Description:

Background: The intervals at which maintenance venom immunotherapy (MVIT) is administered have been progressively extended over the years.

Objective: To examine whether the administration of bee venom (BV) maintenance dose (MD) at 6-month interval is safe and efficacious.

Methods: The usual 3-month interval at which venom allergic patients were receiving their MVIT was gradually extended to 6 months. Systemic reactions (SRs) to immunotherapy injections or to field stings were regularly recorded. BV allergic patients were deliberately sting-challenged after reaching the 6-month interval.
