Background: The prevalence of allergic diseases has risen in the last decades. The objective of this study was to determine the common allergens in children via the skin prick test.Methods: This cross-sectional study recruited 313 allergic children (4 months to 18 years old) referred to the Asthma and Allergy Clinic of Children’s Medical Center in Tehran. A questionnaire containing demographic ...

Since the discovery that Der p 1 is a cysteine protease, the role of proteolytic activity in allergic sensitization has been explored. There are many allergens with proteolytic activity; however, exposure from dust mites is not limited to allergens. In this paper, genomic, transcriptomic and proteomic data on Dermatophagoides pteronyssinus (DP) was mined for information regarding the complete d...

Background: Asthma and allergic rhinitis are among the most common diseases in the world. Objective: The aim of this study was to detect, by skin prick test, aeroallergens in allergic patients in Sari, Mazandaran in north of Iran. Methods: This is a prospective study of skin prick test of aeroallergens in asthma, allergic rhinitis and their combination with clinical diagnosis. Three hundred and...

Of 100 asthmatic patients prick tested for allergy to Dermatophagoides pteronyssinus, 88% were positive compared with only 14% of controls. A significantly greater proportion of dust samples from the houses of the asthmatics contained Dermatophagoides mites. The house-dust mite D. pteronyssinus, constituted 90% of the mites identified, other pyroglyphid mites, Cheyletus and Glycophagus making u...

OBJECTIVES This study aimed to investigate the profile of sensitization to silkworm moth (Bombyx mori) and other 9 common inhalant allergens among patients with allergic diseases in southern China. METHODS A total of 175 patients were tested for serum sIgE against silkworm moth in addition to combinations of other allergens: Dermatophagoides pteronyssinus, Dermatophagoides farinae, Blomia tro...

BACKGROUND Dermatophagoides pteronyssinus, Dermatophagoides siboney and Blomia tropicalis are the most important allergenic mites in Cuba. The aim of this study was to determine the degree of polysensitization and correlation of the skin prick test (SPT) reaction size to these mites in asthmatic patients. METHODS A total of 232 adult patients with asthmatic symptoms caused by house dust and p...

plants. The geographical and climatological condition of Querétaro city, and having a large industrial corridor are risk factors for development allergic problems. In Mexico there are no prevalence studies on food allergy and therefore the most common food allergens. The objectives of the study are to identify common allergen sensitization and to determine if there is crossreactivity between cy...

BACKGROUND AND OBJECTIVE Little is known about the role of molecular diagnosis in house dust mite (HDM) allergy. In this study, we investigated the association between the sensitization profile of adolescent and adult HDM-allergic patients and asthma in a region with high rates of exposure to HDM. METHODS We conducted a cross-sectional study of 384 HDM-allergic patients (38.5%, males; median ...
