BACKGROUND Colophony (rosin) is a natural product obtained from coniferous trees. It is used in a diverse range of products such as adhesives, ink, paints and soldering fluxes. Some workers exposed to colophony during soldering can develop occupational asthma; at present, no specific IgE test is available to assess sensitization to colophony. METHODS Serum samples were obtained from exposed s...

toluene diisocyanate (tdi) is an imperative chemical substance used in the production of polyurethane foams, elastomers, paints and coatings that cause a variety of health problems in workers who are exposed in work places. this study aimed to determine the asthma symptoms and serum specific ige levels in tdi exposed workers and comparing the results with healthy control group.all the plants th...

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 ...

Anaphylaxis caused by allergen sensitization and vaccination is a serious health concern. The severity of anaphylaxis associated with the presence immunoglobulin E (IgE) antibodies that bind to allergens high affinity. Here, we report development unique Interleukin-13 (IL-13)-producing follicular helper T (TFH) cell subset, designated TFH2 cells, which tightly production high-affinity IgE antib...

BACKGROUND Sensitization to Anisakis spp. can produce allergic reactions after eating raw or undercooked parasitized fish. Specific IgE is detected long after the onset of symptoms, but the changes in specific IgE levels over a long follow-up period are unknown; furthermore, the influence of Anisakis spp. allergen exposure through consumption of fishery products is also unknown. OBJECTIVE To ...

Results In 16 patients (42.1%) with negative serum specific IgE tests for both fungi and HDM, total IgE ( 76.1 + 64.7 KU/L) was significantly lower than in 14(36.8%) patients with positive serum specific IgE tests for fungi (730.1 + 948.41 KU/L) and in 16 patients (42.1%). with positive serum specific IgE tests for HDM (783.5 + 854.1 KU/L), respectively. In patients with negative serum specific...

oral allergy syndrome (oas) is occasionally observed following consumption  of raw fruits  in  allergic adults. since this  phenomenon  was  commonly  reported  in  khorasan province of iran; we intended to check if common  diagnostic tests could be applied for differential diagnosis of oas to grapes. ige reactivity of 84 patients with oas to grape and 34 patients with oas to other fruits were ...
