    Notes: Scratch tests (SCT) with powdered commercial spices were performed in 70 patients with positive skin tests to birch and/or mugwort pollens and celery. Positive SCT to aniseed, fennel, coriander and cumin - all from the same botanical family (Apiaceae) as celery -were observed in more than 24 patients. Spices from unrelated families (red pepper, white pepper, ginger, nutmeg, cinnamon) elicited positive immediate skin test reactions only in three of 11 patients. Specific serum IgE to spices (determined in 41 patients with positive RAST to celery) up to class 3 were seen especially in patients with celery-mugwort or celery-birch-mugwort association, and concerned various botanical families. Celery-birch association pattern was linked to positive reactions (RAST classes 1–2) to spices from the Apiaceae family only.CLINICAL ASPECTSAllergy to spices is often observed in celery-allergic patients. In cases with the mugwort-celery association pattern several high RAST values (up to class 3) were seen to various spices from Apiaceae as well as from unrelated botanical families (celery-mugwort-spices association). This sensitization can be of clinical importance, as anaphylactic reactions to spices in food are well documented. The birch-celery association pattern gave some positive RAST results of classes 1–2 to the spices from the Apiaceae family only - suggesting cross-reactivity between Apiaceae and Betulaceae, probably due to thermolabile allergens.

    Notes: We have developed monoclonal antibodies (MoAbs) to the storage mite Lepidoglyphus destructor (Ld). Employing these anti-Ld MoAbs (Ld-MoAbs) in ELISA and ELISA inhibition techniques we have analysed the reaction pattern of Ld-MoAbs to both non-pyroglyphid and pyroglyphid mites. The storage mite Glycyphagus domesticus (Gd) exhibited most efficient inhibition, followed by Acarus siro (As), Tyrophagus putrescentiae (Tp), Dermatophagoides pteronyssinus (Dpt) and Euroglyphus maynei (Em). Of the two pyroglyphid species, Dpt showed at least 1000 times less inhibition than Gd. Two of the MoAbs immunoprecipitated a band of 39 kD whereas the third reacted weakly, with a high-molecular band of approximately 110 kD. The Ld extract was also subjected to various reagents and conditions and the antigen was heat stable, it was not affected by low pH, or sensitive to dimethyl sulphoxide (DMSO) or paraformaldehyde. After exposure of the extract to various reagents, such as protease trypsin and periodate, we conclude that the epitopes recognized by Ld-MoAbs were of carbohydrate rather than of protein nature. It would thus seem that MoAbs recognize the carbohydrate part of a glycoprotein.

    Notes: Sera from forty-two children orally challenged with ovalbumin were analysed for the presence of IgG-ovalbumin immune complexes. The technique used is based on the adsorption of the IgG of the complex to immobilized protein-A and detection of the ovalbumin of the complex on the solid phase, using isotope-labelled, pepsin-digested antibodies to ovalbumin. Children with high serum levels of antibody to ovalbumin had significantly higher concentrations of IgG-ovalbumin complexes than children with low antibody levels. In both groups the appearance of the complexes in the serum was accompanied by a significant decrease of the complement factor C3 (P 〈 0.05). The duration of the decrease in C3 was correlated to the amount of IgG-ovalbumin complexes, suggesting a consumption of C3 by these immune complexes.

    Notes: The prevalence of storage mite allergy was investigated in an epidemiological study of respiratory symptoms in farmers on Gotland, an island in the Baltic Sea. A questionnaire concerning work-related and chronic symptoms from the airways and eyes was completed by 2578 farmers. A sample of 440 farmers subsequently underwent examination comprising skin-prick tests (animal danders, pollens, moulds and house dust mite), blood sampling for RAST against four storage mites (Acarus siro, Lepidoglyphus destructor. Tyrophagus putrescentiae and Glycyphagus domesticus) and total IgE analyses. Immediate onset hypersensitivity reactions in the airways and eyes were very common among active farmers on Gotland, the prevalence being as high as 40.0%. The prevalence of atopic allergy was 15.6%. Allergy to storage mites was diagnosed, from the case history and a positive RAST to at least one of the four storage mites, in fifty-two of 440 studied farmers (12%), corresponding to a calculated prevalence of storage mite allergy in the whole farming population of Gotland of 6.2%. The corresponding prevalence among farmers with hypersensitivity symptoms was 15.4%and among those with possibly IgE-mediated symptoms it was as high as 37.8%. The present study clearly demonstrates a high prevalence of allergy to storage mites among farmers with respiratory symptoms.

    Notes: The present study aimed to investigate to what extent glove powders of different origins and brands bind and release latex allergens. One mineral talc and five cornstarch powders were used. The allergenic material was sap of Hevea brasiliensis. The powders were incubated together with the natural rubber latex sap, and four series of experiments were performed. The talc showed the highest tendency to bind isotope-labeled proteins. When incubated with a latex allergen solution, it reduced free allergen from 100 to 2 units/ml compared to a reduction to 70–98 units/ml for the cornstarch powders. In contrast to the nonstable binding of allergen to cornstarch, the binding to talc was irreversible. The allergen bound to talc was allergenically intact and, when incubated with serum, reduced the concentration of free IgE antibody to latex to 10% of the initial level. Mineral talc had a high capacity to bind latex allergens firmly. In contrast, cornstarch captured the latex allergen, but the binding seemed less pronounced and was unstable. The replacement of talc by cornstarch as glove-donning powder has coincided with the rapid increase in latex allergy. Mineral talc is heavy and only transiently airborne. Could this difference between talc and cornstarch in latex-allergen-binding pattern and the tendency of the latter to be airborne play an important role in the bioavailability of latex allergen and thus in the epidemic of latex sensitization?
