The existence of specific immunoglobulin E (IgE) allows us to determine the allergens that cause the allergic disease. For the purposes of allergen avoidance and immunotherapy, the measurement of specific IgE is widely applied in clinical laboratories. However, if IgE from the serum of an allergic patient exhibits reactivity to multiple allergens, it would cause a problem. The present study ana...

allergy to prosopis juliflora (mesquite) pollen is one of the common causes of respiratory allergy in tropical countries. mesquite is widely used as street trees in towns and ornamental shade trees in parks and gardens throughout arid and semiarid regions of iran. the inhalation of mesquite pollen and several species of amaranthus/chenopodiaceae family is the most important cause of allergic re...

BACKGROUND Lepisma saccharina (silverfish) is a common insect which is often found in human dwellings. Our aim was to determine the IgE antibody pattern to this arthropod in children with allergic respiratory symptoms. METHODS The individual sera and a pool of selected sera of 45 children with asthma and/or rhinitis were used for an immunoblotting test with an extract of Lepisma saccharina; a...

The IgE-binding proteins in beer were examined by immunoblotting analysis with sera of patients sensitive to beer. Several proteins were immunoblotted with the sera, and among these, 18-kDa proteins were identified as new IgE-binding proteins in beer. Perhaps they originated from barley as a raw material.

BACKGROUND Barnacles are a type of seafood with worldwide distribution and abundant along the shores of temperate seas. They are particularly appreciated and regularly consumed in Portugal as well as in Spain, France and South America, but barnacle allergy is a rare condition of which there is only one reference in the indexed literature. The molecular allergens and possible cross-reactivity ph...

BACKGROUND Pollinosis from Amaranthus retroflexus pollen is a common cause of respiratory allergy in Iran with a high positive rate (68.8%) among Iranian allergic patients. The aim of the present study was to evaluate the allergenicity of the A. retroflexus pollen profilin. METHODS Using sera from twelve patients allergic to A. retroflexus pollen, IgE-binding proteins from the A. retroflexus ...

BACKGROUND Patients with atopic dermatitis may experience exacerbations of eczema triggered by various inflammatory stimuli. One mechanism may be IgE-mediated reactions to dermatophytes since these patients are more likely to acquire skin infections with dermatophytes and may become sensitized. OBJECTIVE This study investigates IgE-sensitization to fungi in patients with atopic dermatitis and...

BACKGROUND Allergic reactions after ingestion of fermented soybeans have rarely been reported. Fermented soybeans were recently reported to be a causative food of IgE-mediated, late-onset anaphylaxis without early phase responses. The objectives of our study are to clarify the clinical and laboratory features and to characterize the allergens in allergy due to fermented soybeans. METHODS Seve...

background: anaphylactic reactions, such as urticaria, edema, respiratory symptoms, and anaphylactic shock often complicate the course of cystic echinococcosis (ce). methods: to investigate the role of the ige immunoreactive antigen 5 (ag 5) in the sero-positive patients with ce, we determined n-terminal of 57 kda subunit of ag5 responsible for ige and c-terminal of this active antigen related ...

BACKGROUND At present, data about the cross-reactivity of Blomia spp. comes from studies made among different genera of mites, and no results have been published involving different species of the genus Blomia. OBJECTIVE The aim of this study was to find out the level of cross-reactivity between the two main species of Blomia causing allergy, and its implication in the diagnosis of Blomia sen...
