    Notes: Wickman M, Nordvall SL, Pershagen G, Korsgaard J, Johansen N, Sundell J. Mite allergens during 18 months of intervention.In Stockholm, Sweden, 17 children with newly diagnosed sensitization to house-dust mites (HDM) and 11 children with previously diagnosed HDM-sensitization were included in a study of HDM-allergen avoidance. Mattress dust was collected on repeated occasions during 18 months and assayed for concentration of major HDM allergens. During the first 12 months, the parents of the intervention group were instructed to intensify cleaning and airing of the child's bedroom. During the last 6 months of the study, the mattresses and pillows of seven children in the intervention group and sibling controls were encased in semipermeable polyurethane covers. The homes exhibited a high absolute indoor humidity throughout the year, and even during the winter the mean levels exceeded 7 g/kg. No mite allergen reduction was seen in the intervention group during the first year. However, among the newly diagnosed HDM-sensitized children, there was a mean reduction of the mattress mite allergen concentration of 83% (P= 0.02), and this was most pronounced in the homes with low humidity. At the end of the mattress encasement period, an average difference of 98% (P〈 0.001) was found between the vacuumed amount of mite allergen on top of the covers and that underneath.

    Notes: To examine the association between environmental exposure during the first two years of life and development of atopic disease later in child-hood, 115 children sensitized to airborne allergens and 54 non allergic controls were investigated. Fifty-seven of the atopic children were skin prick test (SPT) positive to house dust mites (HDM). Information on exposure was obtained from questionnaires. Parental allergy was a more important risk factor for development of atopy than any of the environmental risk factors. Exposure during the 2 first yr of life to environmental tobacco smoke (ETS) and home dampness was more frequently found among the HDM-sensitized children than among the controls (OR = 2. 8, CI 1. 0-7. 3 and OR = 4. 6, CI 1. 4-15. 0 respectively). A combination of these two factors seemed to be particularly harmful (OR = 8. 7, CI 2. 3-33. 1). Similar but less pronounced effects were seen for children with other allergies. Later in life exposure both to dampness and ETS was of the same magnitude in the atopic children as in the controls. It appears that exposure to environmental factors during the first few years of life may trigger for development of atopic disease and that interactions may be of particular importance.

    Notes: One hundred and thirty-nine children (85 hoys) from a paediatric allergy clinic were included in a study which aimed to relate disease traits of fungal allergy to measured serum IgE antibodies to fungi. A structured case history was recorded and the children were subject to a panel of skin prick tests which included common inhalant allergens and two fungi, Cladosporium herbarum and Alternoria alternata. Serum IgE antibodies to 16 different fungi were assayed by RAST using the Pharmacia extended panel. Forty-seven of the children were positive to fungal RAST and many of them were positive to multiple fungi. C. herbarum gave the highest frequency of positive results. The best combination of three fungi for detecting fungal sensitization was C. Herbarum, Penicillium notatum and Mucor racemosus. Skin prick test (SPT) failed to uncover fungal sensitization in many children with broad RAST sensitivity. Children with RAST positivity to fungi generally had more severe asthma and more frequently recognised summer and autumn to be a difficult period compared with children without such positivity. In stepwise regression analysis, positive SPT for cat had the best explanatory value for asthma and positive C. herbarum RAST the second best. Children with fungal RAST positivities were not over-represented among cases with allergic rhino-conjunctivitis but there was a strong association to eczema. The latter is possibly explained by concomitant sensitization to fungi colonizing the human skin. It is suggested that the identification of fungal allergy in asthmatic children will help ensure that proper anti-inflammatory treatment is instituted during peak spore periods.

    Notes: The immune response to honey bee venom in thirty-seven bee keepers' sera was studied by several methods. Specific IgE antibody levels studied by RAST were generally low, whereas specific IgG antibody levels studied by a Sepharose protein A technique were high. Crossed radioimmunoelectrophoresis was applied for a detailed analysis of the antibody specificities towards the different components of venom in seventeen of the bee keepers' sera. Significant amounts of IgG antibodies were found towards most bee-venom components. The highest IgG response was directed towards phospholipase A. Hyaluronidase, acid phosphatase and two uncharacterized antigens also showed distinct IgG binding. The IgG binding to melittin was low. The IgE binding to the bee venom components was low and primarily directed to the phospholipase. IgE binding to hyaluronidase and acid phosphatase occurred, but was also in very small amounts. One bee-keeper serum caused heavy radiostaining to melittin but the others did not show IgE binding to this component.Thus a low IgE but a high IgG response was demonstrated in bee keepers. The major immunogen was phospholipase A. which is known to be the major allergen in bee venom. Generally, the strongest IgG responses were found to the components capable of inducing the strongest IgE responses.

    Notes: Serum IgE antibodies were detected with the radioallergosorbent test (RAST) to a panel of allergens which included Pityrosporum orbiculare, Candida albicans, Trichophyton rubrum, Cladosporium herbarum, Staphylococcus aureus, animal dander, deciduous tree pollens, grass pollens and foods in 81 consecutive patients with total IgE ≥ 3000 kU/1. Data on atopic and infectious disease characteristics were collected by a questionnaire. IgE antibody concentrations to P. orbiculare were significantly higher than to the other fungi and of the same magnitude as those to animal danders and pollens. High levels of P. orbiculare IgE antibodies were associated with current eczema, especially when it was the only atopic manifestation and demanding specialist care. IgE antibodies to P. orbiculare had the best explanatory value for current eczema in logistic regression analysis. Head-neck-face dermatitis was also associated with high levels of specific IgE to the yeast. IgE antibodies to S. aureus were detected in few patients and at low concentrations. Six patients had a history of systemic staphylococcal infections and presented a clinical picture, which was very similar to the hyperimmunoglobulinaemia E syndrome. Among the six were the two cases with the highest levels of IgE antibodies to S. aureus. The demonstration of high levels of IgE antibodies to P. orbiculare, which is a major part of human normal skin microflora, suggests that allergy to this yeast plays an important pathogenic role in eczema.

    Notes: The IgE antibody responses to timothy pollen allergens in one rat strain and five mouse strains were investigated by means of crossed radioimmunoelectrophoresis. The rodent strains were selected for their capacity to respond with IgE antibody production. When sensitized parenterally with the antigen mixed in alum, the animals produced IgE antibodies to essentially the same antigens in timothy pollen as timothy sensitive patients have been shown to do. Thus, the allergenicity of the complex mixture of antigens in a timothy extract is similarly expressed in animals immunized parenterally with alum as in patients sensitized by inhalation.

    Notes: A crossed radioimmunoelectrophoretic method was developed for detection of honey bee venom specific IgG antibodies in patient sera. At the serum concentration 1/200 the contrast between specific binding and background was the most favourable. The detection limit was fairly low, approximately 30 kU/1 (IgG RAST units). A reference system based on the reference kits in Phadebas IgG-RAST® was elaborated.
