1/7. Rush immunotherapy in a dog with severe ragweed and grass pollen allergy.

    BACKGROUND: Forty years of study of naturally occurring IgE-mediated allergy in animals is briefly reviewed. These studies provided models for study of bioactive mediators and innovative pharmacologic therapies for IgE-mediated asthma. Objective: Based on our experience with canine allergy we evaluated and treated a dog with severe grass and ragweed allergy whose allergic dermatitis was uncontrolled by H1 blockers and topical corticosteroids. The dog was miserable during the chicago grass and ragweed pollen seasons. methods: Rush immunotherapy was initiated during the ragweed season of 1997. RESULTS: Dramatic improvement was seen which persisted through the grass and ragweed seasons of 1998 after maintenance immunotherapy. CONCLUSION: The case is presented not as a model for canine immunotherapy but as an example of how animal research can be of value to both animals and humans.

2/7. Familial human short-term sensitizing (IgG S-TS) antibody.

    skin tests on a middle-aged English housewife (the initial case) with a history of seasonal grass pollen rhinitis and asthma showed strong immediate and late reactions to grass pollens. Early in the grass pollen season, 1976, RAST showed normal levels of IgE antibodies in the serum. Passive transfer in Rhesus monkey skin was also negative for heat-labile IgE but gave a very vigorous reaction for short-term sensitizing heat-stable IgG antibody (IgG S-TS Ab). skin tests and studies on sera from other members of the family showed that another five also formed IgG S-TS Ab, and indicated that the ability to form this antibody was familial. One member of the family had only an immediate reaction on skin testing, and much IgE to grass pollen. Towards the end of the grass pollen season the IgE titre in the initial case had been tripled and the IgG S-TS Ab had disappeared. By September the specific IgE titre had risen even further.

3/7. Is house dust allergen a possible causal factor for relapses in lipoid nephrosis?

    In three cases of minimal change nephrotic syndrome (lipoid nephrosis), an allergen sensitivity to house dust, cat hair and grass pollen was demonstrated by clinical and biological data. An increase in proteinuria after specific allergen contact and a decrease after withdrawal of the allergens, suggested that the cause was allergenic. Such cases demonstrate the necessity of an etiological investigation of particularly the atopic features in lipoid nephrosis. Results of these investigations can lead to specific therapy in selected cases.

4/7. Buckwheat flour hypersensitivity: an occupational asthma in a noodle maker.

    BACKGROUND: There have been very few reports of occupational allergies caused by inhalation of buckwheat flour. In this paper, we present a case of occupational asthma and rhinitis caused by buckwheat flour inhalation. methods AND RESULTS: The patient had strong positive responses to grass and ragweed pollens as well. The bronchoprovocation test showed early asthmatic response to buckwheat flour extracts. serum specific IgE antibody to buckwheat flour was detected by enzyme-linked immunosorbent assay (ELISA). In order to further identify the allergenic component of the extracts, sodium dodecyl sulphate-polyacrylamide gel electrophoresis (SDS-PAGE) and electroblotting studies were performed. Eight IgE binding components (9-55 kDa) were detected within the buckwheat flour extracts. CONCLUSION: These results suggest that inhalation of buckwheat flour can caused IgE mediated bronchoconstriction.

5/7. hypersensitivity to carrot associated with specific IgE to grass and tree pollens.

    This study deals with a 34-year-old female cook with no previous history of atopy, who was studied because of allergic rhinoconjunctivitis and contact urticaria in both hands associated with severe itching when she handled raw carrot. The patient had had anaphylactic episodes after accidental ingestion of raw carrots, but she tolerated cooked carrots. Skin prick tests with carrot, celery, and olive, and birch, grass, and mugwort pollens were positive. Total IgE was 411 UI/ml. Specific IgE to olive, grass, and weed pollens were 10.92, 6.17, and 2.4 AU/ml, respectively. The histamine release test was positive for carrot, celery, celeriac, and olive pollen up to a dilution of 1/10(6). Immunoblot of raw carrot showed a single IgE-binding 18-kDa band. IgE reactivity for raw carrot immunoblot was completely inhibited by carrot and by celery, but not by olive or grass pollens. Specific IgE to olive pollen was not inhibited by carrot. The existence of monosensitization to an 18-kDa protein in carrot and specific IgE to olive pollen has not been reported in the celery-carrot-mugwort-spice syndrome.

6/7. Inhalative occupational and ingestive immediate-type allergy caused by chicory (Cichorium intybus).

    We report a first case of occupational allergy to chicory (Cichorium intybus) in a vegetable wholesaler. Symptoms occurred after oral, cutaneous or inhalatory exposure. The patient also reported reactions after ingestion of botanically related endive (Cichorium endivia) and lettuce (Lactuca sativa). We identified the responsible allergen by SDS-PAGE and immunoblot to be a 48-kDa protein, confined to the non-illuminated parts of the plants. No cross-reactivity was found with mugwort (artemisia vulgaris), ryegrass (lolium perenne), and birch (betula verrucosa) pollen, which suggests that the vegetable is the primary allergenic material.

7/7. Oral allergy syndrome to a jackfruit (artocarpus integrifolia).

    A 30-year-old man from the philippines with pollen allergy noted the appearance of oral allergy syndrome (OAS) after eating raw apple, raw peach, raw celery, and recently, jackfruit (artocarpus integrifolia), a tropical fruit which belongs to the moraceae family (mulberry) and to the genus artocarpus (breadfruit tree). Despite the patient's multiple sensitization in skin prick tests and in the Pharmacia CAP System to birch, grass, mugwort pollen, related fruits and vegetables, and jackfruit, in RAST-inhibition studies neither rBet v 1 nor rBet v 2 (profilin), the well-known cross-reacting allergenic components in OAS, could inhibit the specific IgE response to jackfruit. Whether the reaction to jackfruit is specific or whether other pollen-related, cross-reacting allergenic components exist should be investigated further.
