Immunoprint pattern in patients with allergic bronchopulmonary aspergillosis in different stages.

Individual immunoprint patterns of sodium dodecylsulfate-polyacrylamide gel electrophoresis-separated Aspergillus fumigatus (Af) allergens/antigens were evaluated in 28 patients with allergic bronchopulmonary aspergillosis in stages II to V. It could be demonstrated that active disease (stage III) is characterized by a very strong IgE response against a variety of Af components, whereas the IgE antibody pattern in corticosteroid-treated patients who have demonstrated improvement is much weaker. In patients in remission (stage II), it is minimal. In contrast, many patients in stage V without corticosteroid treatment demonstrated a strong reactivity of IgE antibodies, indicating persisting active disease. The pattern of IgG antibodies with individual Af components resembles, in general, that of IgE antibodies; however, discrimination between different stages and between treated patients is much weaker. Our results indicate that a certain relationship between the different stages of allergic bronchopulmonary aspergillosis and Af immunoprint patterns exists.

Intolerance to tartrazine in aspirin-induced asthma: results of a multicenter study.

One hundred and fifty-six German, Italian and Polish patients with confirmed aspirin-induced asthma underwent open oral challenges with increasing doses of tartrazine up to 25 mg. All positive challenges were repeated under double-blind conditions. Only 4 of 156 patients (all Polish) had positive reactions in a double-blind test, as evidenced by a fall in FEV1 greater than 25% from baseline and corresponding clinical symptoms. Sixty-five patients who tolerated 25 mg tartrazine well received 50-3,000 mg tartrazine and none showed adverse reactions. Thus, intolerance to tartrazine appears to be rare among Central-European and South-European patients with aspirin-induced asthma, its frequency amounting to about 2.6%.

Pyrazolones and analgesic asthma syndrome.

Many peripherally acting analgesic and anti-inflammatory drugs, including pyrazolone derivatives, can precipitate idiosyncratic hypersensitivity reactions in intrinsic asthmatics. This contribution focuses on the symptomatology, diagnosis, and therapy ('desensitization') in childhood and adult analgesic asthma syndrome.

[Pollen and inanimate dust particles as cause of obstructive airway diseases].

A survey of pollen production, especially in anemophilous plants is first given, because pollen frequently causes respiratory symptoms. Afterwards the use of the Burkard apparatus for volumetric sampling is described, in which the amounts of pollen and fungal spores in a certain volume of air can be caught. It is recommended that, in the country under investigation, several places with different climates each should have an apparatus continuously in operation. then flowering calendars can be constructed to show the various seasons of flowering, and pollen and spore production, and how they vary throughout the country. Meteorological data may also be included in these graphs. G. BOEHM's 'Individual Pollen Collector' is then described. This device is very useful for 'problem patients' with hayfever. Dark stripes of varying intensity resulting from inanimate particles such as dust and soot can also be seen in the daily specimens of the Burkard device. In this case a semiquantitative measurement is possible with a pherogramme evaluator, which is available in every modern clinic. Finally information about the frequency of pollinosis in the population, especially children with asthma, hayfever etc. is given. The prognosis for these patients is discussed and it is noted that there should be more long-term investigations of patients suffering from pollinosis. It would then be better, to give better prognoses for these allergic illnesses.

IgE antibodies to house dust, mite, animal allergens and moulds in house dust hypersensitivity.

Fifty-three patients were investigated by intradermal tests and Phadebas RAST and, in most cases, the serum IgE level was determined. They were tested for sensitivity to house dust, Dermatophagoides pteronyssinus, cat, dog, horse and mould allergens. All cases with IgE antibodies to house dust were found to have specific IgE to other tested allergens as well. Eighty-nine per cent of the patients being RAST positive for house dust were also positive for D. pteronyssinus and in the majority of those cases IgE antibodies to other allergens were detected. The results reaffirm previous findings that the mite is not the only allergen in house dust and that extract of house dust is a mixture of several allergenic substances, which make it less suitable for differential testing. It is concluded that serum IgE determination is of value as a screening procedure in the diagnosis and that the use of a number of specific allergens in RAST is valuable in pinpointing the offending allergen in house dust hypersensitivity.
