Many Germans are aware of the poison of wasps or bees, but few have systemic reactions. That's what Munich allergists have discovered.

MUNICH. Based on the KORA study, allergists led by Simon Blank of Munich's Allergy and Environmental Center had an idea of ​​the sensitization and generalized allergic reactions to the venom of Hymenoptera in the 25 to 75 age group. in Germany (Allergo J Int 2019, online). January 9).

The analysis is based on serum IgE antibody levels against bees and wasps measured in the initial S4 study (1999-2000, n = 4261). On the other hand, it is based on questionnaires in which participants in S4 and in the F4 follow-up study (2006-2008, n = 3074) provided information on local and systemic reactions to bites bees and wasps.

Double awareness at 13.7%

When the limit for specific IgE antibodies (IgE) was set at 0.35 kUA / l, 23.1% of participants were sensitized to bees and 31.7% to wasp venom. 13.7% had dual awareness. Men were more sensitized than women (for example, 29.5% versus 16.9% against bee venom).

4.8% (S4) and 4.4% (F4) of respondents reported only local responses to bee stings and / or wasps. Systemic reactions (ranging from mild general symptoms to shock) have been reported at 2.3% and 2.6%. Women were slightly more affected than men. The wasps and bees were almost tied with the triggers.

Of the people sensitized to bee venom or wasp, 2.8% presented a reaction to the puncture that went beyond a local response.

Surprisingly, there was also a discrepancy between the clinic and the laboratory: among the participants who, according to their own information, had shock symptoms after a bee sting or wasp sting, 49 or 34% had levels of IgE <0.35 kUA / l. (B)
