Background: Aspirin-exacerbated respiratory disease (AERD) is a clinical syndrome associated with chronic inflammation in the airways coincident with chronic rhinitis, sinusitis, recurrent polyposis and asthma. Eosinophils are the key inflammatory cells in the development of AERD. AERD has been attributed to abnormalities of the arachidonic acid me...

We present the cases of 5 patients with a positive clinical history of cutaneous symptoms due to contact with latex products. A latex allergological assessment was made through skin prick tests (SPTs) both with commercial latex extracts and extemporaneous glove extracts, and serum-specific IgE to latex and glove-use tests. In addition, serum-specif...

Background: Cannabinoid (CB) 2 is expressed on immune and inflammatory cells. Identification of 2-arachidonyl glycerol (2-AG) and anandamide as endogenous CB2 ligands has allowed investigations of the roles of CB2 and its endogenous ligand system in inflammatory cells. However, the roles of this receptor-ligand system in inflammatory and allergic i...

Background: Whether breast milk (BM) can protect against allergy has been studied extensively, with conflicting results. Variations in mothers’ BM composition may explain some of the conflicting results. Our aim was to assess the impact of maternal allergy and probiotic intervention on BM food antibodies, transforming growth factor (TGF)-β2 and int...

Background: Patients with nonallergic rhinitis with eosinophilia syndrome (NARES) show typical symptoms of persistent allergic rhinitis (PAR). The aim of the present study was to compare nasal cytokine patterns between NARES and PAR. Methods: Nasal secretions of 31 patients suffering from NARES, 20 patients with PAR to house dust mite and 21 health...

Background: Phl p 5 is a major allergen of Timothy grass (Phleum pratense). A recombinant native Phl p 5 has already been used in clinical trials of allergen-specific immunotherapy as a component of a cocktail of allergens. Recombinant hypoallergenic allergens should further improve the treatment by reducing the risk of anaphylactic reactions at an...

Background: Histamine as an inflammatory mediator plays an important role in chronic allergic and asthmatic conditions. However, the role of genetic polymorphisms of the histamine receptor HRH4 (histamine receptor H4) gene in asthma susceptibility and endophenotypes has not been studied yet. Our aim was to investigate the possible association betwe...

Background: The existence of IgE binding to dog dander extract without IgE antibodies against the described dog allergens (Can f 1, 2, 3 and 4) implies the presence of other dog allergens yet to be identified. Recently, an IgE-binding protein was isolated from dog urine and identified as prostatic kallikrein; it has been named Can f 5. Cross-reacti...

Background: Nitrosative and acid stress play an important role in the pathogenesis of asthma. The aim of this study was to evaluate whether, in asthmatics, a link exists between the concentrations of nitrite/nitrate, ammonia and pH values in exhaled breath condensate (EBC) and asthma severity, lung function, exhaled nitric oxide (FENO), total IgE, ...
