166421. Allergen concentration in natural rubber latex. (Abstract)

seven latex allergens, depending on source and/or preparation procedure. Allergen concentration was reflected in the abundance of mRNA transcripts. When used as the antigen, latex serum may bias the outcome of latex allergy diagnostic tests towards sensitization to Hev b 6. Tests that make use of latex serum may fail to detect latex-specific IgE reactivity in subjects who are sensitized only to allergens that are present at low concentrations.Latex allergy diagnostics and immunotherapy that use

basophil activation test (mBAT), and assess whether such an assay may help to distinguish between potentially relevant and irrelevant IgE reactivity towards 11S globulin proteins.Inhibition immunoblotting and chicken anti-rJug r 4 antibodies were used to determine the cross-reactivity of rSes i 6. Basophils from atopic donors were stripped of resident IgE before passive sensitization with food-allergic sera and challenged with protein extracts or recombinant protein. Basophil activation was measured (...) Ses i 6, the sesame 11S globulin, can activate basophils and shows cross-reactivity with walnut in vitro. Sesame allergy is increasingly being reported, and multi-sensitization to peanut and tree nuts has been described. The clinical relevance and cross-reactivity of many sesame proteins, such as Ses i 6, are unknown.The aims of this study were to perform a preliminary examination of the cross-reactivity of Ses i 6 in vitro, examine the ability of Ses i 6 to activate basophils in a modified

166424. Detection of mouse and rat urinary aeroallergens with an improved ELISA. (Abstract)

Detection of mouse and rat urinary aeroallergens with an improved ELISA. Risk analysis of laboratory animal work presupposes allergen monitoring with sensitive methods. Commercial ELISA kits have recently become available for the detection of mouse (Mus m 1) and rat (Rat n 1) urinary allergen from settled dust samples and air samples with high allergen levels.Our aims were to enhance the sensitivities of the commercial ELISA kits for low aeroallergen levels (less than 1 ng/m(3)) and to test (...) these methods with air samples collected from an animal facility.Personal and stationary air samples were collected from an animal facility during various tasks of laboratory animal work and from various premises of the animal facility.The sensitivities of the ELISA assays were improved with a careful choice of analysis parameters and reagents. The detection limits of 0.1 ng/m(3) for Mus m 1 and 0.8 ng/m(3) for Rat n 1 were established. The sensitized assays enabled detection of mouse and rat aeroallergens

alterations with patients who have aspirin-sensitive asthma.Seventy-four patients with CIU and a history of sensitivity to aspirin and NSAIDs underwent placebo-controlled oral aspirin challenge tests. Concentrations of urinary leukotriene E4 (uLTE4) were measured by ELISA and plasma stable prostaglandin D2 metabolite, 9alpha,11beta prostaglandin F(2) by GC/MS. All measurements were carried out at baseline and after aspirin dosing. Patients were genotyped for the leukotriene C4 synthase (LTC4S) promoter (...) Hypersensitivity to aspirin: common eicosanoid alterations in urticaria and asthma. Aspirin and other nonsteroidal anti-inflammatory drugs (NSAIDs) can precipitate adverse reactions in two apparently different clinical conditions: bronchial asthma and chronic idiopathic urticaria (CIU). Recent evidence indicates that the reactions are triggered by the drugs that inhibit cyclooxygenase-1 but not cyclooxygenase-2.To assess whether patients with CIU and aspirin sensitivity share common eicosanoid

166426. Influence of early life exposures on incidence and remission of asthma throughout life. (Abstract)

Influence of early life exposures on incidence and remission of asthma throughout life. Knowledge of the effects of early environmental and congenital factors on the natural history of asthma may provide important clues to the pathogenesis of asthma.We assessed associations between potential, early determinants and the incidence and remission of asthma throughout life, and tested whether the strength and direction of these associations varied in childhood, adolescence, and adulthood.The data (...) in childhood (HR, 0.62; 95% CI, 0.52-0.75) and positively in adulthood (HR, 2.01; 95% CI, 1.61-2.51). The pattern of associations was similar in sensitized (positive assay to specific IgE) and nonsensitized asthmatic patients.Genetic predisposition and exposure to infectious agents are major early determinants that influence a subsequent history of asthma. The length and type of exposure to infectious agents seem able either to promote or to suppress an anti-inflammatory process, unrelated to IgE, which

166427. Oral administration of a mite allergen expressed by zucchini yellow mosaic virus in cucurbit species downregulates allergen-induced airway inflammation and IgE synthesis. (Abstract)

intraperitoneally sensitized with Escherichia coli bacteria-expressed Der p 5 and orally treated with the virus-expressed Der p 5 (vDer p 5) extracted from the recombinant virus-infected squash plants. Der p 5-specific immunoglobulins were measured by ELISA, and bronchoalveolar lavage assays were used to measure airway inflammation.Infectivity assays and immunoblotting revealed that large quantities of free-form vDer p 5 are produced in the recombinant virus-infected squash plants. The recombinant virus carried (...) and expressed the Der p 5 allergen in squash plants for at least 1 year after numerous passages. In animal tests, squash extract containing vDer p 5 inhibited Der p 5-specific IgE synthesis and airway inflammation.Our results suggest that oral feeding with allergen produced by the plant viral vector provides a novel approach for the therapy of allergic asthma.

had a more severe reaction. CAP analysis revealed Gly m 4-specific IgE in 96% (21/22) of the patients. All patients had Bet v 1-specific IgE antibodies, and 23% (5/22) had positive Bet v 2 results. In IgE immunoblotting 25% (6/22) of the patients recognized soy profilin (Gly m 3), and 64% (14/22) recognized other soy proteins. IgE binding to soy was at least 80% inhibited by birch pollen and 60% inhibited by rGly m 4 in 9 of 11 sera tested. Seventy-one percent (67/94) of highly Bet v 1-sensitized (...) Soybean allergy in patients allergic to birch pollen: clinical investigation and molecular characterization of allergens. Allergic reactions to legumes are generally thought to be acquired by means of primary sensitization through the gastrointestinal tract. Recently, Gly m 4 (starvation-associated message 22), a Bet v 1-related pathogenesis-related protein 10 from soy, was suggested to be an allergen in patients with allergic reactions to a dietary product containing a soy protein isolate.We

166431. Manufacturing and standardizing fungal allergen products. (Abstract)

Manufacturing and standardizing fungal allergen products. The importance of fungal allergen products in the practice of clinical allergy is frequently underestimated. A wide variety of fungal species have been demonstrated to elicit allergic symptoms and to sensitize patients. The quality of fungal allergen preparations might have a significant effect on the specificity and sensitivity of diagnostic tests. Varying degrees of cross-reactivity have been shown among fungal genera, and the clinical

166432. Family history, dust mite exposure in early childhood, and risk for pediatric atopy and asthma. (Abstract)

Family history, dust mite exposure in early childhood, and risk for pediatric atopy and asthma. Dust mite allergen exposure is considered a major determinant of sensitization to these allergens during childhood and a risk factor for pediatric asthma.By using a birth cohort in a setting with a substantial burden of dust mite allergen, we evaluated exposure and risk for outcomes related to allergy and asthma.We collected dust from the bedrooms of 428 children born from 1987 to 1989 and measured (...) Der f 1 and Der p 1 (microg/g dust, combined). Follow-up at 6 to 7 years of age included clinical examination, skin prick testing, specific serum IgE measurement, and methacholine challenge.No overall association was evident for any outcome except bronchial hyperresponsiveness (adjusted odds ratio [OR], 0.62; 95% CI, 0.38-1.00; P <.050; and OR, 0.53; CI, 0.27-1.04; P <.065 for dust mite allergen levels > or =2 microg/g and >10 microg/g, respectively).

166433. How atopic is atopic dermatitis? (Abstract)

How atopic is atopic dermatitis? The extent to which the phenotype of atopic dermatitis (AD) is truly atopic has been the subject of much debate.We sought to systematically evaluate the evidence for the value of measurement of IgE antibodies in diagnosing AD and whether knowledge of IgE sensitization increases clinical diagnostic and predictive ability.We searched Medline from its inception until September 2003. Only studies that measured atopy as either skin prick test positivity or IgE (...) -antibody sensitization to environmental allergens were included within a descriptive analysis. Because the small number of studies of adequate quality did not allow a formal meta-analysis, we assigned strength of evidence according to predefined quality criteria and ranked studies accordingly.Inclusion of atopy as part of the diagnostic criteria for AD did not enhance the criteria's sensitivity and specificity in relation to the clinical phenotype of AD. The strength of association between atopy and AD

166434. In vitro assays for the diagnosis of IgE-mediated disorders. (Abstract)

and standardized. Current analytic methods for IgE antibodies provide more quantitative and reproducible measurements of IgE than ever before, although still with less sensitivity that traditional skin testing. The current challenge is to translate the quantitative IgE antibody results into a more accurate diagnosis of allergic disease. (...) measurements in the diagnosis of non-IgE-dependent disorders (eg, aspirin sensitivity), and modification of IgE antibody assays to measure food-specific IgG antibody for which there is no clinical indication. Basophil mediator release assays have evolved to include flow cytometric methods that can quantitatively detect the presence of cell surface-bound allergen-specific IgE antibodies. Assays for histamine and leukotriene C 4 released after in vitro basophil activation are now more accurate

166435. Viral infections in relation to age, atopy, and season of admission among children hospitalized for wheezing. (Abstract)

higher percentage of wheezing children compared with controls was sensitized to at least 1 of the inhaled allergens tested: 84% (36/43) compared with 33% (15/45; P <.001). The atopic characteristics of wheezing children who tested positive or negative for virus were similar.Viral infections were the dominant risk factor for wheezing among children hospitalized before 3 years of age. By comparison, a large majority of the wheezing children age 3 to 18 years had striking atopic characteristics that may (...) the results in relation to the patient's age, atopic characteristics, and season of admission.This was a case-control study of children (age 2 months to 18 years) admitted for wheezing to the University of Virginia Medical Center over a period of 12 months. Children without wheezing were enrolled as controls. Nasal secretions were evaluated for viral pathogens by using cultures, PCR tests, and antigen detection. Total IgE and specific IgE antibody to common aeroallergens was measured in serum.Seventy

166437. CD4+ T cells migrate from airway to bone marrow after antigen inhalation in rats. (Abstract)

CD4+ T cells migrate from airway to bone marrow after antigen inhalation in rats. IL-5-producing T lymphocytes increase in rat bone marrow after inhalational challenge with allergen.To test the hypothesis that T cells migrate from the airways to the marrow, we examined the trafficking of T cells in Brown Norway rats after sensitization and challenge with ovalbumin.Purified CD4+ T cells, harvested from cervical lymph nodes of naive and ovalbumin-sensitized donors, were labeled with carboxy (...) fluorescein diacetate succinimidyl ester; 20 x 10(6) cells were placed in the trachea of naive or sensitized recipients under anesthesia, and 18 hours later, animals were challenged with inhaled ovalbumin. Cells were harvested 24 hours later from the bone marrow, bronchoalveolar lavage fluid, lungs, the lung blood pool of cells, lung draining lymph nodes, peripheral blood, and spleen.The number of carboxy fluorescein diacetate succinimidyl ester-positive cells, measured by fluorescence-activated cell

166438. Associations between specific serum IgE response and 6 variants within the genes IL4, IL13, and IL4RA in German children: the German Multicenter Atopy Study. (Abstract)

, and therefore the true effect could be masked by other genes or environmental factors.We tested the relationship between these 6 SNPs and sensitization to food, mite, cat, and outdoor allergens in unrelated German children drawn from the Multicenter Atopy Study. Gene-gene and gene-environment interactions were also evaluated.Multiple logistic regression models were used for the analyses of 4 sensitization outcomes.The variant C-1055T was significantly associated with increased risk of sensitization to food (...) and outdoor allergens, with odds ratios of 3.49 (95% CI, 1.52-8.02) and 2.27 (95% CI, 1.04-4.94), respectively. The effects of the TT genotype on food sensitization appear to depend on variants in the IL4RA gene, in which marginally significant interaction terms were observed. Significant evidence supported an interaction between exposure to maternal smoking and variant Gln551Arg on risk of cat sensitization. In addition, we found that the effect of variant C-590T on sensitization to mite depended on Der

release from FcepsilonRI cells sensitized with IgE in vivo or in vitro before exposure to GE2, a critical feature for GE2 to be clinically applicable.GE2 was tested for its ability to inhibit Fel d 1-induced mediator release from human blood basophils from subjects with cat allergy, human lung-derived mast cells, human FcepsilonRIalpha transgenic mice sensitized with human cat allergic serum, and rhesus monkeys naturally allergic to the dust mite Dermatophagoides farinae.Basophils from subjects (...) Inhibition of allergen-specific IgE reactivity by a human Ig Fcgamma-Fcepsilon bifunctional fusion protein. Coaggregating FcepsilonRI with FcgammaRII receptors holds great potential for treatment of IgE-mediated disease by inhibiting FcepsilonRI signaling. We have previously shown that an Fcgamma-Fcepsilon fusion protein, human IgG-IgE Fc fusion protein (GE2), could inhibit FcepsilonRI-mediated mediator releases in vitro and in vivo.We sought to test whether GE2 was capable of blocking mediator

dermatitis, or both.Participants enrolled in the Prevention of Early Asthma in Kids study (n = 285) on the basis of a modified Asthma Predictive Index were characterized on the basis of allergy and asthma questionnaire responses and allergy skin puncture test results.The majority of the children (60.7%, n = 148) were sensitized to either food or aeroallergens. Male children were significantly more likely to be sensitized to aeroallergens ( P = .03) and to have a blood eosinophil level of 4% or greater (...) ( P = .03) and a total serum IgE level of greater than 100 IU/mL ( P = .0004). Additionally, eosinophilia and total serum IgE level had the strongest correlation with aeroallergen sensitization.The high prevalence of aeroallergen sensitization in this high-risk cohort suggests that aeroallergens might have an important role in the early development of asthma. As such, the Prevention of Early Asthma in Kids cohort appears to be an appropriate cohort in which to test whether early intervention
