    Notes: Knowledge of the taxonomic, physiologic, biologic, and ecologic characteristics of allergenic domestic mites contributes to the understanding of the causation of many cases of allergic asthma, and to the measures to be taken to control excessive mite occurrence in homes. Domestic mites, i.e., the combined group of storage mites living in the home environment and of pyroglyphid house-dust mites, belong to the subclass of the acari. This comprises also many other mites of medical and economic importance, together with thousands of free-living mites. Because of some species-specific properties of their allergenic products, it is important that the producing mite is always correctly identified. In spite of their small size (approx. 0.5 mm), domestic mites have well-developed and elaborate systems of respiration, digestion, and water balance, enabling them to live and survive in the various habitats of the home environment. Knowledge of the effects of the various and changing ecologic conditions in the home environment is helpful in developing strategies to prevent the establishment and growth of large populations of allergenic domestic mites.

    Notes: Using an in-vitro test, the presence of formaldehyde-specific IgE antibodies was investigated in sera from four groups of individuals exposed to formaldehyde by different routes and concentrations. Group (A) 28 subjects living or working in rooms or places where formaldehyde-containing construction materials were used: (B) 18 subjects occupationally exposed to relatively high concentrations of formaldehyde; (C) 12 paramedic employees working in a renal dialysis unit where formaldehyde-sterilized dialysers were being used; and (D) 28 subjects undergoing haemodialysis with these formatdehyde-sterilized dialysers. Formaldehyde-specific IgE antibodies could be detected in only one of the 86 serum samples. This particular sample was from a worker occupationally exposed to formaldehyde (group (B)), but who did not show any work-related symptoms. In two pools of control sera from unexposed subjects no specific IgE antibodies to formaldehyde were detected. It is concluded that exposure to formaldehyde, even in relatively high concentrations, rarely evokes the production of specific IgE antibodies. The presence of these specific antibodies is not necessarily attended by allergic symptoms. On the other hand, the symptoms supposed to be related to formaldehyde exposure and reported in this study by 24 out of 28 subjects in group (A), and some of the subjects in groups (B) and (C), cannot be attributed to an IgE-mediated sensitization to formaldehyde.

    Notes: This paper describes observations on the airborne pollen concentrations of four anemophilous weeds of very common occurrence in Western Europe, viz. Rumex spp. (sorrel and dock), Plantago spp. (plantain), Chenopodiaceae (goosefoot family) and Artemisia spp. (mugwort). Comparative results are recorded from London, Leiden, Brussels. Munich and Marseilles for the summers of 1976 and 1977 and this study is one of a series involving international collaboration between workers in cities of the European Economic Community. The literature on the clinical significance of summer weed pollen is reviewed and it is concluded that the pollen of Artemisia is likely to be of importance in areas where the weed is of common occurrence in late summer. The pollen of the other summer weeds is unlikely to be important, but may contribute to the problems of the pollen sensitive patient under exceptional circumstances.

    Evidence of grass-pollen allergenic activity in the smaller micronic atmospheric aerosol fraction (1990)

    Notes: In June 1988, during the grass-pollen season in Leiden, The Netherlands, outdoor airborne paniculate matter was collected and separated into fractions according to aerodynamic sizes (〈inlineGraphic alt="geqslant R: gt-or-equal, slanted" extraInfo="nonStandardEntity" href="urn:x-wiley:09547894:CEA273:ges" location="ges.gif"/〉 10μm, 4·9–10μm, 2·7–4·9μm, 1·3–2·7μm, 0·6–1·3μm, 〈inlineGraphic alt="leqslant R: less-than-or-eq, slant" extraInfo="nonStandardEntity" href="urn:x-wiley:09547894:CEA273:les" location="les.gif"/〉 0·6μm), with a cascade impactor mounted on top of a high volume sampler. The different fractions were tested for the presence of grass-pollen allergenic activity using a RAST-inhibition assay: specific IgE-antibody-containing patient serum was applied on the particle-loaded impaction strips, and the serum was recovered by descending elution for further analysis in the RAST. Simultaneously, continuous measurements were made of the airborne grass-pollen concentration using a volumetric pollen trap. Sampling observations lasting 7–9 hr during a period with relatively high airborne grass-pollen concentrations showed reliably detectable amounts of grass-pollen allergen, not only in the first impaction stage where intact pollen were collected, but also in the lower stages collecting the smaller, paucimicronic and submicron atmospheric aerosol fraction. It is evident that this result has serious implications for the understanding of the bronchial symptoms frequently seen in hay fever patients on days with high pollen concentrations in the air.

    Seasonal appearance of grass pollen allergen in natural, pauci-micronic aerosol of various size fractions. Relationship with airborne grass pollen concentration (1995)

    Notes: In a study during the 1993 grass pollen season at Leiden, the relationship between atmospheric pollen allergen carried by five size fractions of pauci-micronic (few microns) particles and the grass pollen count was investigated. Sampling was carried out on dry days, and atmospheric pollen allergen in the particle fractions was assessed by a RAST-inhibition assay while grass pollen quantities were measured with a volumetric pollen trap. It appears that the atmospheric presence of grass pollen allergen in all size fractions is restricted mainly to the period of presence of grass pollen grains. Before and after the grass pollen season atmospheric grass pollen allergen quantities are generally very low. It is concluded that a routinely performed grass pollen count is a reliable measurement for the estimation of the amount of atmospheric grass pollen allergen, also in the pauci-micronic particle fraction.

    Pollen-related allergy in Europe (1998)

    Notes: The increasing mobility of Europeans for business and leisure has led to a need for reliable information about exposure to seasonal airborne allergens during travel abroad. Over the last 10 years or so, aeropalynologic and allergologic studies have progressed to meet this need, and extensive international networks now provide regular pollen and hay-fever forecasts. Europe is a geographically complex continent with a widely diverse climate and a wide spectrum of vegetation. Consequently, pollen calendars differ from one area to another; however, on the whole, pollination starts in spring and ends in autumn. Grass pollen is by far the most frequent cause of pollinosis in Europe. In northern Europe, pollen from species of the family Betulaceae is a major cause of the disorder. In contrast, the mild winters and dry summers of Mediterranean areas favor the production of pollen types that are rarely found in central and northern areas of the continent (e.g., the genera Parietaria, Olea, and Cupressus). Clinical and aerobiologic studies show that the pollen map of Europe is changing also as a result of cultural factors (e.g., importation of plants for urban parklands) and greater international travel (e.g., the expansion of the ragweed genus Ambrosia in France, northern Italy, Austria, and Hungary). Studies on allergen-carrying paucimicronic or submicronic airborne particles, which penetrate deep into the lung, are having a relevant impact on our understanding of pollinosis and its distribution throughout Europe.

Evaluation of the prevalence of skin prick test positivity to Alternaria and Cladosporium in patients with suspected respiratory allergy. A European multicenter study promoted by the Subcommittee on Aerobiology and Environmental Aspects of Inhalant Allergens of the European Academy of Allergology and Clinical Immunology.This trial was undertaken to study, in several geographically spread European countries, the prevalence of skin prick test (SPT) positivity to Alternaria (A) and Cladosporium (C) in subjects with nasal and/or bronchial symptoms of suspected allergic cause. Each patient completed an anamnestic questionnaire and underwent SPT with a panel of common inhalant allergens and also A and C supplied by three different laboratories, to allow for manufacturer bias. Specific scrum IgE determination was carried out only in subjects with SPT positivity to A and/or C with an immunoassay system. In nine European allergology centers, a total of 877 subjects was enrolled in the trial; 83 of them showed SPT positivity to A and/or C; only nine patients showed monosensitization to A, and none to C The highest percentage of positive subjects was found in Spain (20%); the lowest in Portugal (3%). In the other seven centers, the variation was 7–10%. The age range of mold-positive subjects was 5–60 years. Rhinitis was by far the most common symptom, whether associated or not with asthma and/or conjunctivitis.
