Bee sting anaphylaxis in an urban population of South Australia.
The clinical manifestations and circumstances of bee sting anaphylaxis have been studied retrospectively in 98 subjects. Most reactions occurred in children but the most severe reactions were seen in adult males, of whom 7 lost consciousness and 2 required cardiopulmonary resuscitation. Most stings causing anaphylaxis occurred on the unprotected feet whilst the subject was on lawn in the afternoons in December, January and February when the maximum daily temperature was between 20 and 30 degrees C. This is the temperature range when bees are particularly active in gathering pollen. However, a significantly greater frequency of anaphylactic reactions occurred at higher temperatures when bees are less active, suggesting that high environmental temperature may predispose the individual to greater exposure to bees or possibly to anaphylactic reactions per se. The presence of atopy did not appear to predispose subjects to bee venom hypersensitivity. Considerable anxiety and lifestyle alteration were identified in some subjects. The alleviation of this anxiety is considered an appropriate indication for bee venom immunotherapy.
