Psoriasis is a chronic relapsing disorder that involves the skin, nails and joints. With regard to the role of the immune system in psoriasis, the current study compared serum IgE concentration in patients with psoriasis with control group. Current case-control study was conducted in Dermatology clinic of Razi hospital, Tehran University of medical sciences, Tehran, Iran in 2012. Fifty-eight pa...

BACKGROUND AND METHODS The role of immunoglobulin (Ig) E in immunity against influenza A H1N1 has not been studied. Total serum IgE and specific IgE and IgG anti-H1N1 virus responses were studied in children and adults (n = 2) who received influenza virus vaccination (Flumist(®) or Fluzone(®) ) in autumn 2008 and 2009, and then subsequently became infected with the H1N1 virus in spring 2009. Tw...

BACKGROUND In recent years, increased serum immunoglobulin E (IgE) concentration in patients with cardiovascular diseases has been generating more and more interest. It is as yet unknown, however, if the increased IgE level is a marker of future coronary incidents and whether it may be regarded as an ischemic heart disease risk factor, or if it is indicative of the participation of antibodies i...

BackgroundIgE causes anaphylaxis in type I hypersensitivity diseases by activating degranulation of effector cells such as mast and basophils. The mechanisms that control IgE activity prevent under normal conditions are still enigmatic.ObjectiveWe aimed to unravel how anti-IgE autoantibodies induced we understand their role regulating serum level allergic anaphylaxis.MethodsWe immunized mice wi...

Specific IgE to gliadin was proposed as a marker for wheat dependent exercise induced anaphylaxis, while Tri a 14 was found to induce IgE response in baker's asthma. We evaluated whether these components could be used for discriminating phenotypes of wheat allergy. Twenty-nine patients who were wheat-induced anaphylaxis and/or urticaria (n=21, group I) and baker's asthma (n=8, group II) were en...

The serum levels of IgE and the soluble cleavage product of CD23 (sCD23) were prospectively monitored for up to 1 year after transplantation in 34 patients who underwent autologous (n = 33) or syngeneic (n = 1) bone marrow transplantation (BMT). In 25 patients (74%), a transient IgE peak (two- to 2,750-fold increase) appeared in the serum 3 to 4 weeks after BMT. In 18 patients (51%), a two- to ...

BACKGROUND The anti-IgE monoclonal antibody, omalizumab, is approved in the US as add-on therapy for patients ≥12 years of age with moderate-to-severe persistent allergic asthma. Omalizumab is administered according to the US Food and Drug Administration approved dosing table included in the prescribing information. The dosing table was developed using Genentech's free IgE assay and is designed...

Elevated serum immunoglobulin (Ig)E is the hallmark of atopy, and contributes to asthma and bronchial hyperresponsiveness in atopic individuals. In contrast, the significance of IgE in nonallergic subjects is less clear. The aim of the present study is to clarify a potential association of IgE and asthma in absence of clinical allergy. To this purpose 1,219 consecutive patients of a pulmonary p...
