PURPOSE OF REVIEW IgE-mediated allergy can be treated by subcutaneous allergen-specific immunotherapy (SCIT). However, the percentage of allergic patients undergoing SCIT is low, mainly due to the long duration of the therapy and the risk of severe systemic allergic reactions associated with the allergen administration. Typically, SCIT requires dozens of subcutaneous allergen injections that st...

Allergen-specific immunotherapy has been shown to be clinically effective in patients with seasonal allergic rhinitis and/or asthma. Patients who receive this therapy undergo a number of specific immunologic changes in response to the allergen being administered. These include a "blunting" of the seasonal rise of allergen-specific IgE as well as lowering baseline IgE levels, generation of an al...

We investigated whether exposure to ozone (O(3)) 24 hours after an allergen challenge test would increase airway eosinophilia induced by allergen in subjects with mild asthma with late airway response. Twelve subjects with mild atopic asthma participated in a randomized, single-blind study. Subjects underwent allergen challenge 24 hours before a 2 hour exposure to O(3) (0.27 ppm) or filtered ai...

Montelukast and desloratadine synergistically inhibit the allergen-induced early asthmatic response. Montelukast also suppresses the allergen-induced late asthmatic response, but there are no reports on the effect of desloratadine or the combination on the allergen-induced late asthmatic response. Atopic asthmatics (n = 10) completed a multicentric randomised double-blind crossover study compar...

We investigated the secretion of interleukin (IL)-13 into the airways in 10 mild allergic asthmatics by employing local allergen challenge, and compared the data both to IL-4 levels and eosinophil numbers obtained by bronchoalveolar lavage (BAL). Appropriate allergen or saline were endoscopically instilled into different airway segments, which were lavaged 10 min and 18 h after allergen or sham...

A cross-sectional study was conducted among 393 workers from 21 bakeries to study the relationship between wheat allergen exposure and wheat sensitization and work-related allergic symptoms. Exposure to wheat allergens was characterized by a recently developed and validated immunoassay. Specific IgE antibodies against wheat flour and common allergens were measured by immunoassays, and work-rela...

Background: There are many therapeutic methods for allergic conditions. CpG oli-gonucleotides play a critical role in immunity via the augmentation of Th1 and suppres-sion of Th2 responses. Objective: In the present study we aimed to estimate the effec-tiveness of intranasal administration of CpG ODN plus Chenopodium album allergen in allergic asthma compared with the administration of allergen...

BACKGROUND It has been hypothesized that asthma-related health problems are most severe among children in inner-city areas who are allergic to a specific allergen and also exposed to high levels of that allergen in bedroom dust. METHODS From November 1992 through October 1993, we recruited 476 children with asthma (age, four to nine years) from eight inner-city areas in the United States. Imm...

Background and aim: Eczema is a common inflammatory skin disease. Although history and physical examination are important in diagnosis of allergen, because of extent of environmental allergens, those are not simply recognized. The objective of this study was to determine allergens in patients with contact or atopic dermatitis referred to Razi hospital.Materials and Meth...

Ribosome releasing factor, product of the frr gene in Escherichia coli, is responsible for dissociation of ribosomes from mRNA after the termination of translation. It functions to "recycle" ribosomes and is renamed ribosome recycling factor in this paper. An E. coli strain was constructed (MC1061-2), which carried frame-shifted frr in the chromosome and wild-type frr on a temperature-sensitive...
