Association of features of atopy and diagnostic parameters in hymenoptera venom allergy.
In a total of 525 patients with hypersensitivity reactions to hymenoptera stings diagnostic parameters of hymenoptera venom (HV) allergy (severity of reactions, skin test threshold and RAST for bee and vespid venoms) were investigated for their relationship to the following indicators of atopy: positive history of atopic diseases, elevated (less than or equal to 100 kU/l) total serum IgE and positive prick test reactions to common inhalant allergens (CIA) (grass pollen, cat epithelium, house dust mite). There was a conclusive history of atopic disease in 25%, a total serum IgE greater than or equal to 100 kU/l in 48%, and at least one positive reaction to CIA in 53%. Total IgE greater than or equal to 100 kU/l correlated with a higher frequency of RAST classes greater than or equal to 2 (P less than 0.01) and with less severe reactions to hymenoptera stings (P less than 0.05). In the presence of at least one positive reaction to CIA, there were more frequently skin test thresholds less than or equal to 10 micrograms/ml (P less than 0.05) and RAST classes greater than or equal to 2 (P less than 0.01) for HV than in CIA prick test negative individuals. There was no significant, relationship between the other pairs of parameters evaluated. Thus, reactivity to HV in diagnostic tests is increased in the presence of certain indicators of atopy. This has to be considered in the interpretation of skin test and RAST results obtained with HV.
