Maintenance Bee-Venom Immunotherapy Administered at 6-Month Intervals Does Not Protect Against re-Stings
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.

|Study Start Date:||June 2004|
|Estimated Study Completion Date:||May 2006|
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.
