Condition: Vespid Venom Allergy · Sponsor: Medical University of Graz
Insect venom allergy is the major cause for severe allergic reactions in Europe. Wasps and honeybees are responsible for the majority of these allergic reactions. Symptoms range from generalized skin symptoms (wheals, swellings) to respiratory or cardiovascular problems such as asthma, dizziness, loss of consciousness, or cardiac arrest. The regular administration of insect venom ('venom immunotherapy') over up to 5 years is a well-established therapy, providing long-term protection from further systemic sting reactions in the majority of patients. However, there is no laboratory test which is able to identify patients who will still react to an insect sting. The only reliable method available is stinging patients with living insects ('sting challenges'). The key issue is that only few centers in Europe perform sting challenges and many patients have no access to these tests. Therefore, it is of utmost importance to find a method which is able to identify patients who are still at risk for future allergic sting reactions. The inhibition of the basophil activation test (BAT) could be a potential method to monitor the effectiveness of immunotherapy. Basophils are cells which are activated in acute allergic reactions. The basophil activation of blood donors with vespid venom allergy can be measured after adding sera from allergic patients undergoing immunotherapy. In a preliminary study we found that the activation of basophils could be inhibited in all patients treated with ve…
