[Diagnosis of allergy in bee-keepers. A 1-year prospective study].
Thirty-six Danish bee-keepers were clinically investigated by means of a questionnaire before and after the bee season 1990. Their serum was assayed for IgE and IgG antibody reacting with bee venom, and skin prick tests were performed prior to the season. Thirty-six percent had previously reacted abnormally, either with a systemic reaction (SR) (25%) or a large local reaction (LLR) (11%). Retrospectively, eight of the nine bee-keepers with SR had upon re-exposure developed a normal reaction, in spite of the fact that seven of them had specific IgE and/or a positive prick test at subsequent examination. At follow up 38% of the persons who had previously had a SR reacted with a SR or a LLR on the first sting in the season. Two of eight with previous SR reacted with SR during the observation period in spite of a negative prick test and no specific IgE. Of the bee-keepers who had previously only reacted normally there were no systemic of large localised reactions during the observed period, although six showed signs of IgE-sensitization. The results confirm the problems of identifying patients where immunotherapy is superfluous in the group with previous SR and IgE sensitization.
