    Abstract:
    In Japan, an average of 37 fatalities per year related to bee or wasp stings were reported during the years 1979-1988. To confirm fatal anaphylaxis serologically, we measured bee or wasp venom specific IgE (sIgE) and IgG4 (sIgG4) antibodies in the sera of 22 patients who visited hospitals with either allergic or anaphylactic reactions after bee or wasp stings by using Enzyme-Linked Immunosorbent Assay. Specific IgE or IgG4 antibodies against Polistes apachus (Paper wasp) and/or a mixture of Polistes annularis, P. exceramans, P. fuscatus, and P. metricus venoms of Polistes genus were detected in 11 patients and the detection frequencies were the highest among positive antibodies against bee or wasp venoms. The severity of allergic reactions was graded from 0-4 according to Mueller. The detection frequencies of sIgE in Mueller grade 0-3 patients were in the range of 33% to 67%, and in grade 4 were 100%. Whereas, the detection frequency of sIgG4 was high (67-100%) in grade 2-4 patients. Especially high levels of sIgE and sIgG4 were detected in patients experiencing the most severe clinical reactions. The detection of venom specific IgE and IgG4 antibodies appears to be useful when determining bee or wasp stings as the cause of fatalities.
